Abstract
The present invention refers to means for package sealing. In particular, it refers to a system of machines for package filling and sealing that comprises a pair of oscillating arms opposed and facing each other, simultaneously activated by a main cog through rods. The facing faces of the oscillating arms unite mid-point to them so, in other coordinated operation, to press, cut and seal the sleeve forming the bag in process, which displaces itself through that mid-point. The invention also involves means for pre-piling up in the feeding of the packages, as soon as means for compressing the packages by vibration and compressing the bale formed by the whole of the packages.
Description
- A characteristic of package sealing systems of the prior technique is the complexity of its functioning and of the elements comprising them, where generally linear or gyratory mechanisms are used that require in one or the other case a multiplicity of pieces that operate repetitively to enter and exit a determined cycle of the process. On the other hand, such diversity of pieces require bearings, bars and rotation or pivoting points that it is necessary to lubricate and therefore susceptible of accumulating residue of products that in some way or independently from the material being processed, may result abrasive or at least, to form a kind of paste with the lubricant, preventing the action this last one.
- The present invention appears to solve the aforementioned problems with a simple mechanism and a minimum of pieces,
-
- where besides its movements are limited and of a short run.
- The characteristics and details that define the invention are graphically represented in the annexed illustrative figures, very schematized but expressive of the movement and operation of the whole, wherein the basic operations executed by the system are shown. It is worth observing that in lieu of simplicity only the mechanism of the sealing system and its connected mechanisms are shown, obviating other components such as the bag dragging mechanisms, relays, run limiters, electronic synchronization devices and others used in the specialty, being they of the conventional type. Likewise, each one of
FIGS. 1-4 that follow, show a plain and a connected view tri-dimensionally represented for a better understanding of the several elements and their location. In such cases there only shall be made reference in description to the plain views, through the usual identifying numbering of the elements. -
FIG. 1 , is a view that shows the system at a stage that corresponds to the position of a bag already filled and sealed at its bottom and waiting for the upper seal and where the oscillating arms are at the most distant position between them. -
FIG. 2 , is a view where the main cog has made a descending movement, transmitting the corresponding movement to the oscillating arms through the rods, determining the imprisonment of the bag's sleeve. -
FIG. 3 , is a view that shows the sealing and cutting of the portion of the imprisoned sleeve. -
FIG. 4 , is a view that shows the return movement of the main cog to its initial position of theFIG. 1 (prior to the descent of the sleeve), where the bag being processed has already been sealed and freed. -
FIG. 5 is a partial, schematic view, in projection, of the pre-piling mechanism. -
FIG. 6 is a partial, schematic view, in projection, of the compressing whole of the packages. -
FIGS. 7 a and 7 b show a sequence of compression of the bale formed. - FIGS. 1 to 4 correspond, in a general way, with the sealing stages of the bag, whereas the other FIGS. 5 to 7 b correspond with connected operations of the system.
- From the aforementioned figures and in particular from
FIG. 1 , it can be noted that the system possesses acog 8 foreseen to operate in an alternative way, limited to a part of rotation of same, which is connected mechanically torods 7, in their turn connected, the first one to anoscillating arm 4A further and the second one, to oscillatingarm 4B closer. Oscillatingarms counter-clamps 2, respectively and in the space interposed between said clamps andcounter-clamps 2, there can be found asealing element 5 with an intermediate concavity in oscillatingarm 4A and acounter-sealing element 6, with a cutting knife in oscillatingarm 4B. - A descending
sleeve 3, generally formed by a plastic film, is foreseen to descend at synchronized intervals by a dragging mechanism (not shown) through the mid-space formed by the clamps andcounter-clamps 2, when they are in the position shown inFIG. 1 . - The system condition, shown in
FIG. 1 , is that which corresponds to a “frozen” stage (since the process is continuous) wherein a part of the bag (formed from the sleeve) has already been filled and sealed at its bottom extreme and is waiting for the sealing and upper cut and therefore, set within the space formed between the clamps-counter-clamps 2 and as a consequence of the elevated position of thealternative movement cog 8, which keeps contractedrods 7 and oscillatingarms 4A/4B. -
FIG. 2 shows the moment immediately after the one pointed out forFIG. 1 , wherecog 8 has made a movement of partial rotation downwards, which movement causes that the clamps/counter-clamps 2 should displace themselves to meet at a central intermediate point, imprisoning at said point the previously arranged part of thesleeve 3/bag 1 (FIG. 1 ). In this guise, of imprisonment of the sleeve/bag, which corresponds to the upper part of saidbag 1, take part the elements of sealing 5 and counter-sealing 6 (seeFIG. 3 ), lineally propped and in opposite directions (mechanism not shown, movement indicate by a horizontal arrow) towards the center, wheresuch elements 5 thermally “saw” the plastic film ofsleeve 3 in two parallel areas upper and lower (determined by the two projections in the guise of “C” of element 5), leaning on thecountersealing element 6. This action determines the obtaining of the sealing of the bag's bottom that is going to be formed (upper sealing element) and at the same time defines the upper sealing ofbag 1 already formed (lower sealing element). Thecounter-sealing element 6 possesses a cutting knife that inserts itself during the sealing in the cavity formed by the sealingelements 5, defining now the separation ofbag 1 lower already formed, from the upper bag in the process of formation. However, both parts of the plastic film ofsleeve 3 and ofbag 1 are kept in position by the subjecting effect ofclamps 2. - The later and last stage, before beginning a new cycle, may be seen in
FIG. 4 , where the movement ofcog 8 has again ascended provoking the separation of oscillating bodies4A/4B and therefore of clamps andcounter-clamps 2, wherefore now thebag 1 is freed and drops because of gravity. - An important and novel characteristic of the system, is the movement that oscillating
bodies 4A-4B make and which, of course, is transmitted to clamps andcounter-clamps 2 which imprison the sleeve maker of the bag. It may be seen that this movement is not linear but moreover of a progressive sealing, making a little angular “sweep” of the clamps-counter-clamps that rotate on an imaginary lower apex arranged lower than said clamps. - This particularity determines a uniform sealing, non aggressive, on the sleeve's lamina and therefore a better sealing.
-
FIG. 5 shows the way the packages which are going to be packed or baled pile up, where atransporting belt 9 drivespackages 10 towards afixed platform 12 in a controlled way, so as to form a certain number of packages lined up (two packages in the alluded figure) onplatform 12. This counting of the number of packages is done by a mobile plate 11 connected to a sensor (not shown), in such a way that when a certain number of packages (two in this case) pass, athrust plate 13 is activated, of a movement perpendicular to that of thetransporting belt 9, that will push said packages on a “lung” or mobile box 14, that will go down automatically, in a coordinated manner, as it receivespackages 10, that later and as it has been explained before are sacked inbag 1. - Once the
packages 10 are placed in thebag 1, which has already its bottom formed, the whole ofbag 1 andpackages 10 is subjected to lateral vibrations byplates 15, in such a way thatpackages 10 should get perfectly compressed inside thebag 1, as is shown inFIG. 6 . -
FIG. 7 a is a front schematic view of the bag formed an filled with the packages, already pressed over alower pusher 16, where still there is an upper space vacant, which inFIG. 7 b is eliminated by the thrust upwards ofpusher 16. - It may be seen from all that has been previously expounded, the simplicity and plainness of the mechanisms used, which shall determine the ease of operation and efficiency in production.
