Abstract

The cushioning product includes an elongated paper tube which is crumpled around a periphery to obtain a predetermined resiliency that is greater than the resiliency of the paper tube in an uncrumpled state.

Description

The invention relates to a cushion made of paper, as well as a method and an apparatus for producing the same.

For filling cavities in Packaging of objects are made from paper web by crumpling Upholstery, and methods and devices for their manufacture known in manifold ways. They are based on the edges be wrapped in a paper web and then crumpled. Of This continuously produced band then becomes individual cushion sections in desired Cut off length.

The object of the present invention is to create a cushion of paper that improves Has cushioning properties and is cheaper. With improved Upholstery properties means that the product has a higher elasticity, in other words based on the amount of paper used objects cushioned better. A product is cheaper if it is used to fill out a certain volume less paper is required, for example due to the shape of the upholstery.

Such a product is according to the invention characterized in that the cushion is a paper tube crumpled lengthways is. A paper tube is compressed in the expanded state and crumpled up by it. Compared to previous products, there is more air inside this crumpled Hose "enclosed". The cross section circular Arrangement of the paper leads for improved cushioning and cushioning properties packaged items.

These properties are still there improves that it is preferably provided that at the same time - that is in addition to the wrinkle (Compression) in the axial direction also in the radial direction To provide compression.

The upholstery properties continue thereby improved when the paper tube with a strip in the longitudinal direction is made of paper or adhesive. This is expediently done in that this strip and / or this adhesive layer are formed if one from a paper web by wrapping the edges and joining the same produces a paper tube.

The use is particularly advantageous of kraft paper that is inherently particularly stable.

To manufacture such Upholstery it is advisable to do so beforehand to "configure" a paper tube, that is, to prepare it, in that one or more paper webs along their edges can be connected to one another, for example by direct adhesive overlapping Areas or by sticking strips. These paper tube sheets are then further to the cushions in the appropriate devices or upholstery sections processed.

Such a prepared merged Paper tube web can thus be made smaller, that is to say narrower, that along the two outer sides of the Paper tube insertion folds are provided. With that you can Make more paper available in a small space and put it in the right place transport the paper tube web.

The paper tube web is preferably at prepared standardized intervals with predetermined tear points Mistake. These are places that are exercised as a result of the train they brought about material weakening tear. In other words: if tension is exerted on the paper tube web, it will tear the places where it should "tear" as intended. These are, for example, by perforation and / or by certain cut-outs or recesses are formed.

The process of making the Upholstery and the suitable device are designed such that the paper tube is pulled onto a core that runs along its Has circumferentially distributed rollers (inner rollers) that with outside of the core arranged at least partially driven rollers (outer rollers) interact and pull the paper tube between them pull through and crumble. This is preferably caused by two in the longitudinal direction spaced groups of roles are provided are driven at different peripheral speeds between the two groups of roles of the paper material of the paper tube web that arises when it is pulled through is crumpled up by the second group of roles.

This can still be improved that within the second group of roles mentioned further Rollers are provided, which are arranged on a smaller radius are so that the already crumpled Paper tube also pushed together in the radial direction and at Going through the latter roles is crumpled again.

A device for producing a cushion of paper consists in that means are provided for the paper tube web, which they push onto a core, and that crumpling means, which by the Push onto the core of the expanded paper tube. The conveying means are formed by rollers arranged in a first plane transverse to the conveying direction, which are provided both on the core ("inner rollers") and outside the core in the device ("outer rollers"), which first of all hold the paper tube, once it has been inserted, expand continuously and slide it onto the core. Further groups of rollers are arranged in further planes running perpendicularly to the transport direction of the paper tube web. They then, as already described, bring about the crimping in that a crimp occurs first and then by crimping this crimp as it is passed through the outer rollers and inner rollers.

1 shows a crumpled upholstery or a crumpled upholstery section 1 with the length (when crumpled) a = approx. 28 cm, the inner diameter b = approx. 7 cm and the outer diameter c = approx. 14 cm. It goes without saying that these figures are only for illustration and are not to be understood as restrictive. The upholstery section 1 is created by crumpling a pre-made (configured) paper tube 2 , namely in the form of a compression in the longitudinal direction (axial direction) and subsequent compression. Such a paper tube 2 is in perspective in slightly opened form 2 shown according to the cross section 3 (a) , It is a paper web 6 , which is folded in the manner shown, i.e. with two side folds 2 ' , The folded paper web has a section 3 where the two edges meet 4 ' . 4 '' overlap and using an adhesive layer 7 are glued together. Other possible cross sections of the paper tube 2 are in the 3 (b) . (C) . (D) and (E) shown, wherein in 3 (c) . (D) . (E) strip 5 are provided with which the edges of the folded paper web 6 or two parallel paper webs 6 ' . 6 '' be connected or glued. In this prepared form one also speaks of a configured paper web or paper tube web 8th ,

The paper is preferably so-called "kraft paper", ie very strong brown wrapping paper made from unbleached sulfate pulp, usually using very long fibers and therefore particularly tear-resistant. Of course, this information is also only to be understood as an example. As already mentioned, the sheets are glued together. The adhesive layers which are strip-shaped in the longitudinal direction of the cushion section 7 form; if necessary with the strip 5 , an additional stiffening of the upholstery, which increases the upholstery properties.

4 shows a basic design of a paper processing unit 35 to create a cushion 1 , On a wave 10 sits a role 11 , It is configured by a wound paper tube web 8th educated. This hose is on a core 15 by two pairs of driven rollers 16 raised and upgraded. A pair of roles 16 is clear; another pair sits vertically in front of and behind the plane of the 4 in the same vertical plane. On the roles 16 follow roles 17 , which are driven at a slightly lower speed, so that a folding between the two 8th' due to compression that occurs during the passage of the paper tube web 8th between the roles 17 and the core 15 undergoes crumpling. Two more roles 17 are arranged in the same vertical plane, in 4 in front of and behind the core 15 , with their axes perpendicular to those of the roles shown 17 , To the core 15 are free running pairs of roles 20 . 21 . 22 . 23 . 24 arranged, which serve the low-friction running along the paper tube on the outside of the core. The roles dive 16 , as in 4a shown by an amount h (immersion depth) between the rollers 20 . 21 one so they're the core 15 Secure in a defined position against axial displacement.

One possibility is to separate individual upholstery sections from the continuously produced band 5 out. Here is also a paper tube web in plan view 8th shown, the perforation lines at intervals of, for example, 80 cm as a "predetermined breaking point" 12 having. Along these lines are diamond-shaped cutouts, for example half a width apart from the paper tube web 13 intended. If you hold the reels in predetermined time periods that correspond to the processing of a certain length segment 16 and leaves the roles 17 keep turning, then along the perforated line 12 then between the roles 16 and 17 lies, a cushion section 1 tore off. The tearing off can also be carried out by other means arranged in the transport direction T before or after the device shown. A separation of the upholstery sections by a cutting device or other separating devices is of course also possible.

A simple construction of a frame with a paper processing unit 35 to produce such a cushion section is in 6 shown.

The frame for the various components consists of a base plate 30 and a scaffold 31 , the rolling 32 and 33 on which configured paper tube webs 8th are wound up. The top roll 32 is the one of which is just a paper tube web 8th deducted and processed. role 33 is stock roll. At the top of the scaffold 31 is by rail 37 , Slot 36 and locking screw 39 the processing unit is adjustable in height 35 arranged. By rolling 38 the device can be moved. The inclusion of the two roles 32 and 33 is axleless on other roles (not shown).

The 7 to 12 show in detail an embodiment of an apparatus for producing a cushion section 1 ,

Out 7 is a rack 40 can be seen on the right side two roles 41 and 42 are provided, on which a roller without an axle 11 a paper tube web 8th is arranged.

How best to look 8th can be seen outside the core 15 and therefore also referred to below as "outer rollers", four upper rollers 43 . 44 . 45 . 46 and paired lower roles 43 ' . 44 ' . 45 ' . 46 ' to see. At right angles to this, but with axes in the same vertical plane, are also pairs of rollers, which are also opposite one another 61 . 61 ' . 62 . 62 ' . 63 . 63 ' . 64 . 64 ' provided (see also 11 ). These pairs of roles work on the core 15 arranged freely rotating rollers together, namely the pair of rollers 51 . 51 ' the couple 52 . 52 ' , the two pairs of roles 53 . 53 ' and 54 . 54 ' , the couple 55 . 55 ' , There are also further pairs of the "inner rollers", which, however, are arranged with their axes perpendicular to the axes of the rollers mentioned in the same vertical plane (in the exemplary embodiment), so the pairs of rollers 71 . 71 ' . 72 . 72 ' . 73 . 73 ' . 74 . 74 ' . 75 . 75 ' (compare also 9 . 12 . 14 .)

The interaction of only one of the outer roller pairs, namely the outer roller pairs 45 . 45 ' and 63 . 63 ' with the two at the core 15 spaced roller pairs 53 . 53 ' and 54 . 54 ' secures the core 15 against axial displacement despite its free storage; compare the explanations above 4a , Since the outer rollers are driven and engaged with the inner rollers, the paper tube web becomes so 8th pulled between the outer and inner rollers and thereby unfolded between them due to different driving speeds of the outer rollers and then crumpled.

The paper tube web is drawn in through the two opposite pairs of rollers 61 . 61 ' and 43 . 43 ' , during the exit of the compressed roll through the pairs of rolls 64 . 64 ' and 46 . 46 ' he follows.

A central electric drive motor is used to drive the "outer rollers" 80 provided to which a gearbox 81 is flanged to reduce the speed of rotation. The output shaft 82 is with the gear 83 connected, the first, deflected by 90 °, the shaft 84 , and secondly the wave 85 drives, which in turn, in the transmission 83 ' deflected by 90 °, the shaft 99 drives. On the wave 84 the gears sit 90 and 91 , Over a chain 220 drives the gear 90 the gear 92 on the wave 93 and over chain 221 the gear 94 on the wave 95 , The wave 95 extends into the transmission from above 96 into it, which, deflected by 90 °, the shaft 97 drives itself into the gearbox 98 stretched in, the, deflected by 90 °, the shaft 86 and thus roles 62 ' drives. On the wave 95 also sits a gear 100 that over a chain 222 the gear 101 drives and thus the shaft 102 on which the role 64 sitting. The wave drives equally 99 a gear 103 (see 8a ) that over a chain 223 the gear 107 and with it the wave 108 and thus the role 61 ' drives. Some of the vertically arranged rollers run freely. The role 44 on well 109 ' is via a bevel gear connection 109 to the wave 86 coupled. It goes without saying that toothed belts can also be used instead of chains. In this way you can manage with just one motor.

Through different translations from the shaft 82 on wave 85 on the one hand (gear 82 ) and wave 84 on the other hand on wave 95 (Gears 91 . 94 ) is achieved that in the vicinity of the catchment area, that is to the right in 8th , lying roles 61 . 61 ' . 62 . 62 ' run a little faster than the downstream rollers in the direction of transport 63 . 63 ' . 64 . 64 ' so that the above unfolding 8th' can arise.

Groups of roles are addressed in the claims. In the embodiment according to the 1 to 5 the first group is formed by those roles whose axes in the vertical planes A and B (based on the embodiment according to 8th to 12 , i.e. perpendicular to the transport direction T of the paper tube) (compare 12 ). The second group of roles is formed by those roles that lie in the vertical plane C. The third group consists of the roles in level D.

The two inner rollers (e.g. 53 / 54 ) that have an external role (e.g. 51 ) and assigned to each other by the symbol "/" have to the in 12 Plotted C a certain distance, which is not important in the present context. They work together with a third role and serve the core 15 to fix in the axial direction (see the explanations above 4a ).

The rollers of the first group run at a "first" peripheral speed, the rollers of the second group at a "second" peripheral speed which is less than the first peripheral speed. This creates a unfolding (compare 8th' in 4 ), which is also crumpled when passing through the second group.

As it passes through the rollers of the third group of level D, crumpling takes place again, due to the smaller diameter of the core 15 at this point also in the radial direction. This radial reduction in diameter occurs when the paper tube passes from section 200 to section 201 (see 13 ). Diameter is not to be understood strictly here, but refers to the approximate radius around the plates 130 . 131 . 150 . 151 at the respective point. So there is a total crimping (compression) of the paper tube in the axial direction and one in the radial (compression) direction, the latter with / after reducing the diameter of the core and thus of the paper tube.

In the 13 to 15 is the structure of the core 15 shown in more detail.

How out 13 and 14 to see is the gist 15 of two parts, namely a front part in the direction of transport 120 and a rear part in the transport direction 121 built up. With 120 ' is the dividing line. Both parts are connected to each other, in the specific case by the front part connecting element 125 has, on the one hand by means of the screw 126 with the front part 120 , on the other hand by means of the screw 127 with the back part 121 connected is.

If one looks at the two parts in their assembled state as a whole (cf. 14 ), it turns out that the core 15 essentially from an upper plate 130 and a lower plate 131 consists of spacers 140 . 141 . 142 , which are arranged between them, by means of screws 145 are interconnected. The rollers are then between the plates 71 ' to 75 ' (and behind it, therefore not visible, the roles 71 to 75 ) arranged.

On the top plate 130 and on the bottom plate 131 are each, continuous (but in two parts according to the front part 120 and the back part 121 ) two to the plates 130 . 131 vertical parallel parallel plates 150 . 151 arranged to store the rolls 51 to 54 , or on the bottom 51 ' to 55 ' , serve.

16 shows a modular design, another embodiment in which all roles within a box-shaped frame 230 are arranged, which consists of two rectangularly curved frame sections 231 and 232 consists of the elbows 233 are screwed together. Out of the frame 230 the wave sticks out below 234 out. It corresponds to the wave 84 to 8th and 8a and is connected to a drive motor that is in 16 is not shown connected. Within the module, the core is also fixed between the rollers in the axial direction. A guide plate is adjustable on the frame by means of screws 236 arranged over the guide surface 237 the paper tube web 8th can be supplied. The paper tube web is over the mushroom-shaped inlet head 238 pulled, expanded and pulled between the rollers.

Like from the 20 and 23 the wave carries 234 the outer role 241 and drives over the two bevel gears 301 and 302 the wave 303 and with it the role 251 , The wave 303 then drives over the bevel gears 304 . 305 the wave 306 and with it the role 241 ' , The wave 234 also drives via the bevel gear 307 and the bevel gear 308 the wave 309 on which the role 251 ' sitting. The roles 241 . 241 ' . 251 . 251 ' work on the inner tube 310 , the part of the core 235 is, freely rotatable rollers 261 . 261 ' . 262 . 262 ' . 271 . 271 ' . 272 . 272 ' so together that when driving the shaft 234 a paper tube sheet 8th is pulled between the outside rollers and the inside rollers. The roles 261 . 261 ' . 271 . 271 ' sit perpendicular to the plane of the 20 just before the roles 262 . 262 ' . 271 . 271 ' (see 19 . 26 ). The two in pairs in front of and behind the level 20 Arranged "inner rollers" interact with the "outer rollers" to axially fix the core.

On the wave 303 ( 20 ) sits on one side (right) of the roll 251 the gear 311 , the gear on the other side 312 ,

The gear 311 drives the gear via chain or toothed belt (not shown) 313 on the wave 314 (please refer 21 ). The wave 314 carries the bevel gears 315 and 316 that over the bevel gears 317 and 318 the waves 319 and 320 drive. This way the roles sitting on it 240 . 240 ' . 250 . 250 ' driven which in turn with the rollers 260 . 260 ' . 270 . 270 ' cooperate in such a way that a paper tube web between them 8th can be drawn in and pulled through.

The gear 312 ( 20 ) drives the gear via a chain or a toothed belt (not shown) 325 on (see 22 ) on which the wave 326 who sits the role 252 wearing. The wave 306 drives over the bevel gears 327 . 328 . 329 . 330 the waves 331 and 331 ' and with it the roles sitting on it 242 and 242 ' , At the bottom of the wave 331 sits a bevel gear 332 which is a bevel gear 333 drives. This drives the wave 234 and therefore the role 252 ,

In this embodiment, the roles 242 . 242 ' . 252 . 252 ' ("Outer rollers") no corresponding and interacting rollers on the core or on the inner tube 310 assigned. To the crumpling of the between these rollers on the one hand and the inner tube 310 on the other hand, the rollers have the effect of improving and improving the already crumpled and now radially compressed hose and at the same time supporting its conveyance in the transport direction T. 242 . 242 ' . 252 . 252 ' pens regularly distributed along its circumference 335 on.

The shafts are each in bearings 359 the in strips 350 to 357 (please refer 17 ) are provided. The strips are the frame sections 231 and 233 screwed, for example by the screws 358 (please refer 16 ).

A paper web hose 8th is thus manually in the transport direction T at the beginning of the process on the core 235 wound between the roles 250 . 250 ' . 240 . 240 ' (Outer rollers) and the rollers 260 . 260 ' . 270 . 270 ' (Inner rollers) inserted and, as soon as they grasp it, are then continuously drawn in between them and pulled between them as a result of the fact that the outer rollers are driven in the manner described. Then they are between the roles 251 . 251 ' . 241 . 241 ' (Outer rollers) and the rollers 261 . 261 ' . 262 . 262 ' . 271 . 271 ' . 272 . 272 ' (Inner rollers) pulled through, but at a lower speed. So there is a folding between these two groups of roles, which is not shown in these figures, but compare 4 (there 8a ). The first group consists of the outer roles 240 . 240 ' . 250 . 250 ' and the inner rollers 260 . 260 ' . 270 . 270 ' , The second group consists of the outer roles 241 . 241 ' . 251 . 251 ' and the inner rollers 261 . 261 ' . 262 . 262 ' . 271 . 271 ' . 272 . 272 ' , In order for the unfolding to take place, however, the diameter of the paper web tube must be correspondingly larger than that of the core.

The different speed of the first and the second group of rollers results from the fact that the gear ratio of the gear 311 ( 20 ) on the gear 313 is designed accordingly.

A further bulge then takes place when the radial distance is reduced (in relation to the center line of the inner tube 310 ) the paper web tube when transported from this second group of rolls to the third group of rolls formed by the rolls 242 . 242 ' . 252 . 252 ' , These are "outside roles". This embodiment does not have “inner rollers”. Nonetheless, further crumpling takes place. The rotational speed of this third group of rollers is determined by the gear ratio 312 ( 20 ) to gear 325 ( 22 ).

In addition, it should be mentioned that the inner rollers on the inner tube 310 are stored in such a way that on the inner tube corresponding U-shaped bearing bracket 360 are screwed on ( 20 . 21 ).

For braking outer rollers of the first group of rollers, that is, more precisely, the driven outer rollers 240 . 240 ' . 250 . 250 ' (see 21 ) at the "predetermined tear points" 9 / 9 ' (please refer 5 ) It is intended to tear off the paper web tube: On the shaft 320 ( 21 ) is a brake wheel 361 , by a spring 362 in a groove 363 fixed, arranged. The brake wheel 361 can, like from 24 visible through a brake band 365 be brought to a standstill when the electromagnet 366 is excited. Then the anchor 367 on which the holding rod 368 with the brake band 365 are attached, pulled in about 2 millimeters in the direction of the arrow. The brake band 365 excited and the movement of the shaft 320 stopped. This stop then leads to a corresponding stop in in consequence of the transmission connection via bevel gears and shafts 21 shown external roles 240 . 240 ' . 250 . 250 ' ,

So despite the stop mentioned, the driven rollers 241 . 241 ' . 251 . 251 ' ( 20 ) is the gear 313 ( 21 ) by Welle 303 about the gear 311 and toothed belt is driven on the shaft 314 , by means of a slip clutch 370 stored in 25 is shown in more detail. This slipping clutch enables the second group of rollers to continue rotating while the first group is stopped. Then the paper web hose breaks.

The slip clutch works like this: the roller 250 is on the wave 314 in the groove 369 by means of the spring 370 stored. The gear 313 is on the side of the role 250 but is not firmly connected to it. Inside the gear 313 is another gear 371 arranged whose left shoulder 371 ' on an assigned shoulder surface 313 ' of the gear 313 sitting. The gear 371 is with the wave 314 through the also with the groove 369 engaging spring 372 coupled in the direction of rotation and is (in 25 ) from right to left to contact the gear 313 pressed. In one with an internal thread 373 ' provided recess 373 of the gear 371 is a set screw 374 screwed. She squeezes with her outer shoulder 374 ' on the disc spring 375 , which in turn with its outer leg bent inwards 375 ' on the gear 313 Exerts pressure. The set screw 373 is fixed in the axial direction by being on an external thread of the tube 376 is screwed on the shaft 374 using a pen 377 is firmly arranged. So the stronger the set screw 374 is turned (to the left in 25 ), the more the diaphragm spring presses 375 with her thigh 375 on the face of the gear 303 , This is the wave 314 with the gear 313 frictionally coupled. However, the coupling is dimensioned such that when - as described - the shaft 314 is stopped, overcoming this friction the gear 313 can continue to rotate. The set screw 374 can be adjusted from the outside by engaging a corresponding pin in one of the cross holes 378 ,

The braking device, consisting of electromagnets 366 and brake band 365 is with a support plate 380 connected to the frame section 232 (see 26 ) is screwed.
