Description

Storage goods extractor for an automatic storage system

The invention relates to a storage product extractor for an automatic storage system, also an extractor arrangement and an automatic storage system with such a storage product extractor and a method for storage and retrieval of stored goods. Automatic storage systems are, for example, paternoster systems or storage lifts. Such systems are often used, especially in small parts stores.

Storage goods extractors are commonly used to transfer stored goods from the storage system storage facilities to a conveyor or from the conveyor to the storage facility. The bearings are usually arranged one above the other in storage levels of shelf columns. Often the stored goods are stored on mounting rails. Also in the horizontal direction juxtaposed bearings are known.

The conveyor is usually driven horizontally and / or vertically movable in storage systems to approach the bearings and to move the stored goods for storage and retrieval between the bearings and a removal / feed opening of the storage system back and forth. The stored product extractor is often attached to the conveyor.

At the unloading / loading opening, the stored goods can be removed from the storage system or stored in the storage system. For the transfer of the stored goods between conveyor and unloading / loading opening or between two connected storage systems also stored goods extractors can be used.

For stored goods belong in stored goods carriers and directly, without load-carrier, stored items. For example, trays, containers, but also devices in which articles can be hung are used as load-carriers. Directly stored stored goods, for example products packed in boxes, are often stored directly on the carrier rails of size-adapted shelf columns.

Different types of storage product extractors are known from the prior art. For example, US Pat. No. 3,750,804 shows telescopic arms for transferring stored goods from the bearings to a central conveyor or vice versa. The arms have a complex mechanism and require a complex control system.

The US 4,358,239 shows in pairs, each guided on two parallel chain drives driver, each in a throat on the conveyor side facing the end of a storage product container retract and pull the container onto the conveyor. The disadvantage of this solution is that the containers must be equipped with a matching the drivers throat. The direct storage of stored goods without load-carrier is therefore not possible. The same problem arises in the solutions of EP 1 473 254 B1, WO 01/56905 A1 and DE 4 233 260 A1, which also have driven drivers.

In the extractor of EP 0 192 259 B1 telescopic arms are extended, the movable jaws are pressed laterally against the stored goods and pull it on the conveyor. This solution appears due to a two-stage conveying movement constructive and control engineering consuming.

The object of the invention, in view of the known solutions, to provide a storage product extractor, which is simple in construction and does not require complex control. The stored goods extractor should also be light to allow high accelerations.

This object is achieved by a storage product extractor of the type mentioned, with at least one movable in a horizontal conveying direction between two end positions storage sled, which has an upwardly facing support surface for stored goods, and with at least one linear drive, through which the at least one storage sled straight is guided, is provided, wherein the storage product carriage is at least partially adjacent to the linear drive in its two end positions.

For the method mentioned in the introduction, the object is achieved in that after starting a bearing a stored goods extractor with a storage sled performs the following steps: straight-line method of storage sled with the stored thereon stored goods in a horizontal conveying direction from or to the bearing point, straight-line method the storage product carriage in the horizontal conveying direction directly under the storage goods stored in the storage facility, wherein the storage product carriage is held and driven laterally next to the stored goods.

This solution initially has the advantage that stored items can be handled by the stored goods extractor without load-carrier. The stored material simply rests on the support surface of the storage sled and requires only a stable floor surface, which in most cases is also present. The geometry of the stored material does not have to be adapted to the stored goods extractor. Thus, the throats are eliminated, which are necessary in Lagergut extractors with drivers. The control and the mechanical structure can be designed simply in the solution according to the invention due to the simple kinematics of the linear drive. Thus, the vertical movement of the stored goods extractor can be generated in particular at storage lifts from the conveyor, which carries the stored goods extractor. The drive power of the conveyor is designed anyway for rapid acceleration even with heavy stored goods. For the storage product extractor, the linear drive is sufficient. This makes it very easy to build the storage product extractor.

The embodiment of the invention has the further advantage that the stored material rests on removal and storage on the support carriage and does not have to be moved along the support rails. This reduces the wear on the stored goods and, because of the lower friction during removal and storage, the energy expenditure.

Finally, in the solution according to the invention, a structurally complex, telescopic design can be dispensed with, because in the end positions the linear drive driving the storage product carriage is located next to the storage product carriage. As a result, the storage product slide is guided laterally over the entire stroke and supported. Consequently, only minor leverage occurs in the end positions.

Overall, this results in a lightweight and simply constructed storage product extractor, which allows high accelerations and still be able to accommodate heavy stored goods.

The solution according to the invention can be further improved by the following, in each case advantageous and arbitrarily combinable embodiments.

Thus, the at least one linear drive according to a first advantageous embodiment, a traction drive, such as a belt, in particular toothed belt, a chain or a cable drive comprise. These embodiments are inexpensive to implement. In the end positions, the storage product carriage can be approached by deflecting members of the traction mechanism drive, such as, for example, deflection and / or drive rollers. Instead of a traction drive can also be used a linear motor.

The storage product carriage may have a transport position, which is located in the horizontal conveying direction preferably centrally between the two end positions. Preferably, the transport position does not overlap with the end positions. Such an embodiment is particularly suitable for storage systems in which the storage locations with respect to a storage shaft, in which the conveyor moves with the storage product extractor, opposite each other. In the transport position, the storage product sled, but in particular the entire storage product extractor, can be located outside the cubature of the storage locations. This makes it possible to move the storage product sled or the stored goods extractor past the storage locations, so that the stored goods can be transported by the conveyor through the storage shaft. The transport position can also be characterized in that the stored goods extractor has at least in the horizontal direction smaller dimensions than in the end positions, preferably the smallest dimensions also in comparison to all intermediate positions.

When used in a storage system is according to a further advantageous embodiment of the storage product slide in at least one of, preferably in both, end positions at least partially within the cubature of the bearing points of a rack column. In such an end position, the storage product carriage preferably overlaps completely in the vertical direction with the storage goods located above it. The storage product carriage can therefore safely lift or store the stored goods in the final position.

According to a further advantageous embodiment, two storage product carriages can be provided, one of which is connected to a linear drive assigned to it. The storage product carriages may be located laterally, transversely to the horizontal conveying direction, opposite each other and spaced from each other. Such a spacing allows a tilt-safe resting of the stored material on the support surfaces. The volume located between the storage slides is advantageously unobstructed in order to keep the weight of the stored goods extractor low. The storage sled can be driven together, for example via a common drive shaft.

The stored product extractor can also form a horizontally conveying direction continuously extending, preferably unobstructed extractor shaft. Through such an extractor shaft, stored goods can be transported in the horizontal conveying direction to the two opposite ends of the stored goods extractor, where they are then delivered or picked up by further conveying devices or by operating personnel.

The extractor shaft can be bounded laterally by two, in particular, panel-shaped side cheeks. The side cheeks can extend in an elongated horizontal conveying direction. On at least one of the side cheeks, preferably on both side cheeks, one or respectively one linear drive can be held. The side cheeks may be part of the load-bearing extractor supporting structure. Preferably, they are made of a sheet metal material. In a central region of the extractor, between the end positions, there may be a support frame via which the stored product extractor may be connected to the conveyor. The support frame may be formed portal-shaped. The extractor shaft may extend through the support frame.

The stored product extractor is adapted with its dimensions to the predetermined and predetermined dimensions of the shelf column and / or the usually standardized dimensions of the stored goods. A standard for the dimensions of the stored goods, for example, the standard VDA 4500, which sets the dimensions for EUROFIX containers.

The stored goods extractor can have at least one end located in the horizontal conveying direction, two legs projecting in the horizontal conveying direction, on each of which at least one linear drive can be held at least in sections. The legs are in particular stationary relative to the storage sled and therefore preferably do not move with the slack. They are preferably used as holders for the linear drives. The legs may be formed by the side cheeks described above. At the lying in the horizontal conveying direction ends of the legs may be pulleys of the linear drive, so that the storage product carriage can be driven almost to the end of the legs.

The legs with the parts of the linear drive mounted thereon may be part of a lateral boundary of the extractor shaft.

A lateral distance between the legs is preferably greater than the standardized and / or predetermined width of the stored material, so that stored material fits between the legs therethrough.

The legs can also be further apart than the predetermined or predetermined width of a shelf column. In this embodiment, the stored goods extractor preferably laterally encompass the shelf column with its legs. The overlap makes it possible to move the at least one storage product carriage from the side outside the shelf column far to the front. In particular, the storage product carriage can always be spaced equidistant from an attachment point over its entire travel distance lying between the end positions, as the storage product carriage is connected to the linear drive. In this embodiment, the storage product carriage is supported equally well over its entire travel, so that even with heavy stored goods, the storage product extractor can be lightweight. The fastening point may in particular comprise a metal sheet angle, which connects the storage product carriage simultaneously with the linear drive and the guide rail, if the latter is present.

The support surface may protrude or rest in the horizontal conveying direction of the attachment point at least on one side. By the projection, it is possible to move the support surface in the horizontal conveying direction behind the attachment of the support rail to the shelf column. The stored material can thus be supported over a large depth.

The storage sled is preferably made of a sheet material by forming. The support surface of a storage sled is preferably elongated in the horizontal conveying direction. The length of the support surface in the horizontal conveying direction is preferably a multiple of its width. The distance between two storage product carriages is preferably greater than the length of the storage product carriages in the horizontal conveying direction.

The positions of the at least one storage product sled preferably overlap in the two end positions and, if a transport position is present between the end positions, also the transport position, do not overlap one another. The two end positions can be at least one length of the support surface in the horizontal conveying direction spaced from each other.

It is furthermore advantageous if the storage product carriage has at least one groove-shaped carrier rail pocket extending in the horizontal conveying direction, which is open at at least one end located in the horizontal conveying direction and has a bottom which lies below the supporting surface. When retracting the storage sled into the rack column travels in this embodiment, the support rail of the shelf column. The mounting rail pocket is open at the top.

Further, the, preferably each, linear drive according to a further advantageous embodiment, at least one extending in the horizontal conveying direction guide rail. On the guide rail, the storage product carriage can be held linearly displaceable. The guide rails may be attached to the legs or side cheeks described above. Like the linear drive assigned to it, a guide rail can extend up to the side of the mounting rails of a bearing column. For this purpose, the clear width between two mutually opposite mounting rails is preferred as the width of the shelf column.

The guide rails can be located above or below the linear drive and / or the associated support surface. The stored product extractor in one of the above embodiments may be part of an extractor arrangement with which, for example, an existing storage system can be retrofitted. The extractor assembly may further comprise at least a pair of mounting rails for storing stored goods. The mounting rails are usually mounted in the shelf columns. Advantageously, the mounting rails on a provided with fastening means and a cantilevered end. The cantilevered end can be provided without fasteners, such as openings for receiving screws or rivets. The height of the mounting rail can decrease with fasteners provided to cantilever end decrease.

The freely projecting at one end support rails allow a particularly deep retraction of the support surface in the cubature of the shelf column in the horizontal conveying direction with compact dimensions of the stored product extractor. As a result of the projection, it is possible for the linear drive assigned to the storage product carriage to move laterally outside the shelf column next to the support slide if this is already located between the mounting rails.

A storage system provided with a storage product extractor in any of the above embodiments may include a plurality of laterally spaced, cantilevered support rail pairs on which stored goods can be stored at a vertical distance from each other. The mounting rails may in particular be clamped substantially on one side, in which they are connected at only one end with at least one post, for example, a shelf column in which a plurality of bearings are arranged in superimposed bearings.

In order to allow a deep retraction of the at least one receiving carriage, the freely projecting in the horizontal conveying direction length is preferably at least one third, more preferably at least half of the total length of the support rails in the horizontal conveying direction.

If two storage product carriages are present, their greatest common width is preferably smaller than a clear width between the carrier rails so that the storage product carriages can enter between the carrier rails. In the case of only one storage product carriage, its width is preferably smaller than the clear width between the carrier rails.

The stored goods extractor can, as already described above, embrace the mounting rails or shelf column on the outside laterally or on three adjoining sides. In particular, the linear drive and / or the guide rail are at least partially laterally outside next to the mounting rails or the shelf column. The total width of the stored goods extractor is preferably at most as large as a width of the support rails supporting the shelf column including side posts. In this embodiment, a plurality of shelf columns can be operated side by side, each with an outsize them embracing, only vertically traversing stored goods extractor. In the horizontal direction, the load-carrier preferably extends to just before laterally projecting posts.

In at least one end position, the support surface may be moved between the support rails, wherein preferably the support surface is located in at least one end position completely in the cubature of the shelf column or the bearing points. This makes it possible to use most of the or the entire bearing surface the storage of stored goods.

Furthermore, in at least one end position, the carrier rails can be retracted into the carrier rail pockets of the storage product carriages. When resting on the support rails stored goods the retracted support rails are preferably spaced vertically from a bottom of the support rail pocket according to a further embodiment. As a result, the storage product carriages can be lifted when the carrier rails are retracted relative to the carrier rails. The distance in the vertical direction between the bottom of the receptacle and the mounting rails is preferably greater than the distance between the bearing surfaces of the stored goods. Thus, the bearing surface can approach the stored goods and lift off from the mounting rails without the mounting rails colliding with the storage sled.

The invention is explained in more detail below with reference to the accompanying drawings with the aid of a schematically illustrated embodiment. The combination of features described below can be changed in accordance with the above statements within the solution according to the invention, it should not depend on the advantages associated with individual features in individual applications.

For simplicity, the same reference numerals are used in the drawings for elements that correspond to each other in function and / or structure.

First, the construction of a storage product extractor 1 according to the invention will be described with reference to FIG. Figure 1 shows the stored goods extractor 1 for the sake of clarity without storage system. The stored goods extractor 1 is characterized by a simple and lightweight construction.

The stored product extractor 1 has at least one storage product carriage 4 which is movable in a horizontal conveying direction 2 and on which stored goods 6 can be deposited for conveying purposes.

The stored product extractor 1 is used, for example, to move the stored goods 6 from or into a storage location (not shown) of a storage system (also not shown) and thus to load or unload the stored goods. For storage, the stored material 6 is moved from the storage material extractor 1 in the bearing. For removal, the stored material 6 is removed from the storage site. The stored material 6 can be handled directly by the storage product extractor 1, for example in a box or box form, or on load-carriers such as trays or containers or hanging devices.

In the stored goods extractor of Figure 1, a pair of opposite in a width direction 8 stored goods slide 4 is present, of which only one can be seen. In the following, reference is made only to a storage product carriage 4. Preferably, both storage sled 4 are constructed identically.

The stored material 6 rests on the storage product carriage 4 on a bearing surface 10. The support surface 10 is elongated in the horizontal conveying direction 2. It is located on the top of support strips 1 1, which can be made of angled sheet metal material. A length 12 of the support surface 10 in the horizontal conveying direction 2 is a multiple of its width 14 in the width direction 8. The support surface 10 biases a support plane 16, on which a bottom 17 of the stored material 6 comes to rest.

The support surface 10 does not have to be continuous, but can be distributed over a plurality of punctiform support points.

The stored product extractor 1 is provided with at least one linear drive 18. Preferably, each storage product slide 4 is assigned a linear drive 18. It contains a traction drive 19 - Figure 1 shows an example of a toothed belt drive - designed and generates a translational, preferably linear drive movement of the support carriage 4. As a drive, the storage product extractor 1 has a motor 20. Preferably, the linear drives 18 are coupled to each other, so that the motor drives all storage goods slide 4 together. For this purpose, for example, a common drive shaft 21 may be provided.

The linear drive can have a guide rail 22 for each storage product carriage 4, through which the storage product carriage is guided linearly in the horizontal conveying direction 2. The guide rail 22 preferably receives the weight of the stored material 6, so that only the propulsion in the horizontal conveying direction 2 is to be supplied by the linear drive 18.

As FIG. 1 shows, an attachment point 24, via which the storage product carriage 4 is connected to the linear drive 18 and / or the guide rail 22, can be formed from a simple sheet-metal angle. The support surface 12 or the entire storage sled may also be formed from a simple formed sheet metal, which is continuous in a development and extend integrally to the attachment point 24 and may also include this. The bearing surfaces 10 project in the horizontal conveying direction 2 on at least one side opposite the fastening point 24, so that they project in the horizontal conveying direction 2.

The stored goods extractor is provided with a continuous in the horizontal conveying direction 2, unobstructed extractor shaft 26, through which the stored material 6 can be transported using the Lagergutschlitten to the two located in the horizontal conveying direction 2 ends 28 of the stored product extractor. At the ends of the stored goods can be delivered. A clear width 27 of the extractor shaft 26, which may be bounded laterally by the linear drive 18 and / or the guide rails 22, is preferably larger than a generally standardized width 31 of the stored goods 6.

The side cheek 32 can, as shown in FIG. 1, delimit the extractor shaft 26 laterally at the two sides of the stored product extractor 1 situated in the width direction 8. The side wall can in particular be designed panel-shaped and made of sheet metal material.

As can also be seen, the side cheek 32 can serve for fastening the linear drive 18 and / or guide rail 22. The side wall 32 takes on the weight of the stored material 6 and passes it to a support frame 36 in a central region 34 of the storage product extractor. The support frame 36 is connected to a conveyor of the storage system, of which in Fig. 1 only by way of example attached to the support frame 36 traction means 38 can be seen.

The support frame 36 may be configured portal-shaped by the extractor shaft 26 extends through it and is surrounded on three sides by the support frame. At an upper cross member 40 of the support frame, which is located above the extractor 26, an attachment point 40 for the conveyor, not shown, or the cable 38 may be provided.

Lateral vertical members 44 of the support frame are preferably laterally au ßerhalb the side cheeks 32. They may have guide members 46, for example in the form of rolling or sliding bearings on which the stored product extractor 1 is guided in the vertical direction 48.

The stored product extractor 1 extends away from the center region 34 in the horizontal conveying direction 2 substantially fork-shaped. It has for this purpose at least one in the horizontal conveying direction 2 located end 28, 30, preferably at both ends 28, 30 two projecting legs 50, 52, which span between them a receiving volume 54, which may be in particular a component or one end of the extractor 26.

The at least one guide rail 22 and / or the at least one linear drive 18 preferably extends as far as or at least close to the end 28, 30 of each leg 50, 52 so that the storage product carriage 4 reaches close to the end 28, 30 located in the horizontal conveying direction 2 of the stored product extractor can be driven. The motor 20 is preferably located below, the guide rail 22 preferably above the support surfaces 10 and the support plane. The legs 50, 52 and side cheeks 32 are stationary relative to the storage sled 4, so do not move with this.

Below the extractor shaft 26 and the bearing surfaces 10, a bottom part 56, the side cheeks 32 connect together. For stiffening it can be provided with running in the width direction beads or folds.

FIG. 2 shows the storage product extractor 1, wherein the two storage product carriages 4 are located in an end position 58 located in the horizontal conveying direction 2. In the end position 58, the stroke of the linear drive 8 in the horizontal conveying direction 2 is exhausted. As can be seen, the bearing surfaces 10 protrude in the end position 58 in the horizontal conveying direction 2 via the end 28 of the storage product extractor in the transport position (Figure 1) or the end of the legs 50, 52 and side cheeks 32 addition. A part of the support surfaces 10 is still in the receiving volume 54 between the side walls 32 and legs 50, 52nd

The Lagergutschlitten 4 form a groove-shaped support rail pocket 60 which is open at least on one side in the horizontal conveying direction 2, namely to the end position 58, and upwards. A bottom 62 of the support rail pocket 60 is below the support surface 10 and the support plane 16. The support rail pocket 60 is located in the width direction 8, ie laterally outside the support surfaces 10th

The length 12 of the support surfaces 10 otherwise corresponds to at least about a depth 64 of the stored goods. The stored material is preferably stored transversely, so that the smaller dimension in the horizontal conveying direction 2 has.

At the other end 30 located in the horizontal conveying direction 2, a further end position 66 of the storage product carriages 4 may be present, as FIG. 3 shows. The end position 66 differs from the end position 58 due to the symmetrical structure of the stored goods. Extractor 1 in the horizontal conveying direction 2 only by a reversal of direction, so that the sake of brevity refer to the comments on the end position 58 in Figure 2.

With reference to FIGS. 4 to 10, the function of the stored product extractor 1 in a storage system 70 will be explained below by way of example, of which only a shelf column 72 and a storage shaft 74 are shown for the sake of clarity. A second, with respect to the storage shaft 74 of the shelf column 72 opposite shelf column is omitted for ease of illustration.

In a rack column 72 are located one above the other several storage locations 76, in which stored goods 6 can be stored. The shelf column 72 consists of at least one pair of opposite in the width direction 8 posts 78 to which support rails 80 are attached. The support rails 80 may have an L-shaped cross section in the horizontal conveying direction 2. On them the stored material 6 is in a storage level 81. Their position determines the situation of the situation levels 76.

In the storage shaft 74 of the stored goods carrier 1 in the vertical direction 48 by the conveyor, not shown, movable so that the bearing surfaces 10 of the storage sled 4 and its support plane 16 (see FIG. 1) can be moved to each bearing 76 and storage level 81 ,

The support arms 80 are preferably formed projecting, as Figure 4 shows. They have a free end 82 and a clamped end 84. The length 86 in the horizontal conveying direction 2 of the projecting end 82 is preferably at least one third, more preferably at least half of the entire length 88 of the support rail 80.

As can be seen, fasteners 90, with which a support rail 80 can be attached to the post 78, are present only at one, the clamped end 84 of a support rail 80. The clamped end 84 is located at the end remote from the storage product extractor 1 end of the support rail 80th

The stored goods extractor 1 laterally surrounds the bearing points 76 so that it can only travel vertically along the shelf column 72 in the illustrated embodiment. The stored product extractor 1 extends in particular next to the free ends 82 and extends in horizontal conveying direction 2 up to the post 78 zoom. In Figure 4, the stored product extractor 1 is empty and moved up to a bearing 76 for removal. The bearing surfaces 10 and bearing planes 16 are located slightly below the bearing 76, so that the Lagergutschlitten 4 can retract in the horizontal conveying direction 2 below the bearing 76 in the cubature of the shelf column 72 until the end position shown in Figure 3 or 4 58, 66 is reached ,

The stored material 6 is, as Figure 5 shows, arranged in the bearings 76 in the vertical direction 48 at a distance 92 from each other. The distance 92 is greater than a height 94 of lying in the horizontal conveying direction 2 in front of the bearings 76 section of the storage sled 4. Thus, it is possible that the storage sled 4 with below the storage level plane lying support surfaces 10 between two superimposed bearings 76 can retract. For this purpose, an outer overall width 96 of the storage sled 4 is smaller than the clear width 98 between the pair of support rails 80, as can be seen in Fig. 6.

In FIGS. 6 and 7, the storage product carriage 4 has arrived in the end position 58. The storage product 6 completely overlaps the support surface 10 in the vertical direction 48.

The support rail 80 is retracted into the support rail pocket 60 of the support carriage 4. It lies in the region of the projecting part between the support surface 10 and the linear drive 18. In the vertical direction 48, the support rail from the bottom 62 of the support rail pocket 60 is further spaced than the support surface 10 of the bottom 17 of the stored product. 6

Next, the stored product extractor 1 is moved upwards by the conveying device (not shown) in the vertical direction 48, so that the support surfaces 10 of the storage product carriages 4 are moved from below within the carrier rails to the stored goods 6 and in the further vertical movement the stored goods 6 from the Lift support rails 80. This state is shown in FIG. 8.

Subsequently, the storage product carriages 4 are moved back to the transport position 5 with the storage goods 6 resting thereon, so that the storage product carriages 4 and the storage goods lying on them no longer overlap with the cubature of the shelf column 72 (FIG. 9). In this position, the stored product extractor 1 can then be moved together with the stored goods 6 in the vertical direction, as Figure 10 shows.

For storing stored goods 6 in a storage location 76, the steps illustrated with reference to FIGS. 4 to 10 are simply carried out in the reverse order. Since the end positions 58, 66 are present on both sides of the stored goods extractor, removal and storage of stored goods are possible on both sides of the stored goods extractor located in the horizontal conveying direction 2.
