Abstract
The invention relates to a crumpled paper tube for use as a cushion in packing items, and to a method and apparatus for producing the same.
Description
- The invention relates to a cushion of paper, and to a method and an apparatus for producing it.
- In packing various items, many kinds of cushions for filling voids are known, which are produced from paper web by crumpling. They are based on folding or rolling the edges of a paper web inwardly and then crumpling the folded or rolled paper web. From this continuously created web, individual cushion portions are then cut off to a desired length.
- The object of the present invention is to create a paper cushion which has improved cushioning properties and is less expensive. Improved cushioning properties means that the product has higher resiliency and/or elasticity, or in other words provides better cushioning of items packed, in proportion to the quantity of paper used. A cushioning product is less expensive if less paper is required to fill a given volume, for example on the basis of the way in which the cushioning product is shaped.
- One such product is characterized according to the invention in that the cushion is a crumpled paper tube. A paper tube, in the opened-out state, is upset and thereby crumpled. In comparison with previous products, more air is “trapped” inside this crumpled tube. The circular cross-section disposition of the paper leads to improved properties in cushioning and padding packed items.
- These properties are improved still further by preferably providing that the paper tube is crumpled in the longitudinal direction and in the radial direction.
- The cushioning properties are furthermore improved if the paper tube is provided in the longitudinal direction with a strip of paper or adhesive. This is expediently effected by providing that this strip and/or this adhesive is formed when a paper tube is produced from a paper web by folding or rolling in the edges and joining them together.
- It is especially advantageous to use kraft paper, which is already intrinsically especially stable.
- For producing such a cushion, it is expedient beforehand to “configure” a paper tube, that is, to prepare it, specifically by providing that one or more paper webs are joined together along their edges, for instance by directly adhesively bonding overlapping regions or by gluing strips on. These paper tube webs are then processed further to form the cushions or cushion portions in the apparatuses suitable for that purpose.
- A paper tube web prepared and put together in this way can as a result be made smaller, or in other words narrower, by providing that along the two outer sides of the paper tube, in the flatly put-together state, indented folds are provided. Thus in a small space, more paper can be furnished and transported to the places where the paper tube web is processed further.
- The paper tube web is preferably provided with intended tearing points at prepared, standardized intervals. These are points which tear when tension is exerted, as a consequence of the weakening of the material brought about by them. In other words, if tension is exerted on the paper tube web, it tears at the points where it is “supposed to” tear as intended. These points are preferably formed by a perforation and/or by certain notches or recesses.
- The method for producing the cushion and the apparatus suitable for it are embodied such that the paper tube is slipped onto a core, which distributed over its circumference has rollers (inner rollers) that cooperate with rollers disposed outside the core (outer rollers), at least some of which are driven, and that thus draw in the paper tube, pass it between them, and crumple it. This is preferably accomplished by providing that two groups of rollers, spaced apart from one another in the longitudinal direction, are provided, which are driven at different circumferential speeds, so that between the two groups of rollers, crumpling by way of creasing of the paper material comprising the paper tube web occurs, and this creasing is crumpled further upon the passage through the second group of rollers.
- This can be improved still further by providing that within the second-named group of rollers, further rollers are provided, which are disposed on a smaller boundary circle, so that the already-crumpled paper tube is also pushed together in the radial direction and crumpled anew on passing through the last-named rollers.
- An apparatus for producing a cushion of paper comprises the provision of feeder means for the paper tube web that slip it onto a core and the provision of crumpling means, which crumple the paper tube web that has been opened out by being slipped onto the core. The feeder means are formed by rollers disposed in a first plane transverse to the feeding direction, which are provided both on the core (“inner rollers”) and outside the core (“outer rollers”) in the apparatus; all of these rollers initially continuously open out the paper tube once it has been inserted and then slip it onto the core. In further planes extending perpendicular to the transport direction of the paper tube web, further groups of rollers can be provided. They then, as already described, accomplish the crumpling in that first a circumferential creasing occurs by virtue of longitudinal compression, and then a radial compacting occurs by virtue of radial compression ensues.

- FIG. 1 shows a crumpled cushion, or a crumpled cushion portion1, having the length (in the crumpled state) a=approximately 28 cm, the inside diameter b=approximately 7 cm, and the outer diameter c=approximately 14 cm. It is understood that these figures are intended solely for purposes of illustration and are not to be understood as limiting. The cushion portion 1 is created by crumpling a prefabricated (configured)
paper tube 2, specifically in the form of upsetting in the longitudinal direction (axial direction) with ensuing compression. Onesuch paper tube 2 is shown in perspective in slightly opened form in FIG. 2, in terms of the cross section of FIG. 3(a). It involves a paper web 6, which is folded as shown, that is, with two lateralindented folds 2′. The folded paper web has aportion 3, at which the twoedges 4′, 4″ overlap and are glued to one another by means of anadhesive layer 7. Other possible cross sections of thepaper tube 2 are shown in FIGS. 3(b), (c), (d), and (e), and in FIG. 3(c), (d), (e), strips 5 are shown with which the edges of the folded paper web 6, or of two parallel paper webs 6′, 6″ are joined or glued together. In this prepared form, the term used is also a configured paper web, or apaper tube web 8. FIG. 3(f) illustrates another possible cross section ofpaper tube 2 wherein two parallel paper webs 6′, 6″ are joined or glued together viaadhesive layers - The paper is preferably so-called “kraft paper”, that is, very firm, brown packing paper made of unbleached sulfate cellulose, usually using very long fibers, which is therefore especially tear-resistant. It is understood that this statement should again be understood only as an example. The webs are glued together, as already mentioned. The
adhesive layers 7 that are striplike in the longitudinal direction of the cushion portion form, optionally together with the strip 5, an additional reinforcement of the cushion, which enhances the cushioning properties. - FIG. 4 shows one basic embodiment of a
paper processing unit 35 for creating a cushion 1. Aroll 11 is seated on a shaft 10. The roll is formed by a configured, wound-uppaper tube web 8. This tube is drawn onto a core 15 by two pairs of drivenrollers 16 and kept on hand there. One pair ofrollers 16 can be seen; a further pair is located perpendicularly before and behind the plane of FIG. 4, in the same vertical plane. Therollers 16 are followed byrollers 17, which are driven at a somewhat lower speed, so that between the two creasing 8′ ensues from upsetting, and upon passage through thepaper tube web 8 between therollers 17 and the core, this creasing undergoes crumpling. Twofurther rollers 17 are disposed in the same vertical plane, in FIG. 4 in front of and behind thecore 15, with their axes perpendicular to those of therollers 17 shown. Pairs ofrollers core 15 and serve to provide for low-friction travel along the paper tube on the outside of the core. As shown in FIG. 4a, therollers 16 plunge by an amount h (plunging depth) between therollers 20, 21, so that they secure thecore 15, in a defined position, against axial displacement. - One possibility for cutting off individual cushion portions from the continuously manufactured band is seen in FIG. 5. Once again, a
paper tube web 8 is shown in plan view that hasperforation lines 12, or tearing points or lines of separation, at intervals of 80 cm, for instance. Along these lines, for instance at the spacing of half the width of the paper tube web,rhomboid cutouts 13 are provided. If therollers 16 are now stopped at predetermined time intervals, which correspond to the processing of a particular longitudinal portion, and therollers 17 are allowed to continue to rotate, then along the perforated line that is then located between therollers - One simple design of a stand with a
paper processing unit 35 for producing such a cushion portion is shown in FIG. 6. - The stand for the various components comprises a bottom plate and
scaffold 31, which has rolls 32 and 33 onto which configuredpaper tube webs 8 are wound. Theupper roll 32 is the one from which apaper tube web 8 is just now being drawn off and processed.Roll 33 is a reserve roll. On the upper end of thescaffold 31, by means ofrail 37,slot 36 and lockingscrew 39, theprocessing unit 35 is disposed so as to be adjustable in height. The equipment can move from place to place by means ofrollers 38. The mounting of the tworolls - FIGS.7-12 show one exemplary embodiment of an apparatus for producing a cushion portion 1 in more detail.
- In FIG. 7, a
stand 40 can be seen, on the right-hand side of which tworollers roll 11 of apaper tube web 8 is disposed without a shaft. - As best seen from FIG. 8, outside the
core 15 and therefore hereinafter also known as “outer rollers”, fourupper rolls lower rollers 43′, 44′, 45′, 46′ can be seen. Transversely to this, but with axes in the same vertical plane and also facing one another in pairs, further pairs ofrollers core 15, namely the pair ofrollers pair rollers pair rollers - The cooperation of only one of the outer pairs of rollers, namely of the outer pairs of
rollers rollers core 15, secures the core 15 against an axial displacement, despite its being freely supported; in this respect, see also the explanation above for FIG. 4a. Since the outer rollers are driven and are in engagement with the inner rollers, thepaper tube web 8 is thus drawn through between the outer and inner rollers and, as a consequence of different drive speeds of the outer rollers, is folded between them and then crumpled. - The drawing in of the paper tube web is effected by the two pairs of
rollers rollers - For driving the “outer roller”, a central
electrical drive motor 80 is provided, to which agear 81 for stepping down the rotary speed is flanged. Thepower takeoff shaft 82 is connected to thegear 83, which in turn first drives theshaft 84, deflected by 90°, and second drives theshaft 85, which in turn, deflected by 90° in thegear 83′, drives theshaft 99. Thegear wheels shaft 84. Thegear wheel 90 drives thegear wheel 92 on theshaft 93 via achain 220 andgear wheel 91 and drives thegear wheel 94 on theshaft 95 viachain 221. Theshaft 95 extends from the top inward into thegear 96, which deflected by 90° drives theshaft 97, which extends into thegear 98, which deflected by 90° drives theshaft 86 and thus theroller 63′. Also seated on theshaft 95 is agear wheel 100, which via achain 222 drives thegear wheel 101 and thus theshaft 102, on which theroller 64 is seated. Theshaft 99 likewise drives a gear wheel 103 (see FIG. 8a), which via a chain 223 drives thegear wheel 107 and thus theshaft 108 and thus also theroller 61′. The rollers disposed perpendicularly move freely in part. Theroller 44 onshaft 109′ is coupled to theshaft 84 via abevel gear connection 109. It is understood that pulleys may be used instead of the chains. In this way, it is possible to make do with only one motor. - By means of different gear ratios from the
shaft 82 to theshaft 85 on the one hand (gear 83) andshaft 84 toshaft 95 on the other (gear wheels 91, 94), it is attained that therollers rollers aforementioned creasing 8′ can occur. - Groups of rollers are described herein. In the exemplary embodiment of FIGS.1-5, the first group is formed by those rollers whose axes are located (see FIG. 12) in the vertical planes A and B (in terms of the exemplary embodiment of FIGS. 8-12, that is, perpendicular to the transport direction T of the paper tube). The second group of rollers is formed by those rollers that are located in the vertical planes C. The third group forms the rollers in the plane D.
On the apparatus On the core 15: outside the core 15: Group Vertical Plane “Inner Rollers” “Outer Rollers” First A 51, 75, 51′, 75′ 43, 61, 43′, 61′ B 52, 74, 52′, 74′ 44, 62, 44′, 62′ Second C 53/54, 72/73, 45, 63, 45′, 63′ 53′/54′, 72′/73′ Third D 55, 71, 55′, 71′ 46, 64, 46′, 64′ - Each two inner rollers (such as53/54) that are associated with an outer roller (such as 51) and are associated with one another by the symbol “/” have a certain spacing from the plane C shown in FIG. 12, but this spacing is not critical in the present situation. They cooperate with a third roller and serve to fix the core 15 in the axial direction (see the explanation above for FIG. 4a).
- The rollers of the first group travel at a “first” circumferential speed, and the rollers of the second group travel at a “second” circumferential speed that is less than the first circumferential speed. The result is a crease (see8′ in FIG. 4), which upon passage through the second group is also crumpled.
- Upon passage through the rollers of the third group in plane D, crumpling occurs again, specifically as a consequence of the lesser diameter of the core15 at this point, including in the radial direction. This radial decrease in diameter takes place at the transition of the paper tube from the
portion 200 to the portion 201 (see FIG. 13). The term “diameter” is not meant to be understood strictly here but instead pertains to the approximate outline around theplates - In FIGS.13-15, the construction of the core 15 in detail.
- As seen in FIG. 13 and FIG. 14, the
core 15 is constructed of two parts, namely afront part 120 in terms of the transport direction and arear part 121 in terms of the transport direction. The dividing line is marked 120′. The two parts are joined together, in this specific case in that the front part has a connecting element 125, which is connected on the one hand to thefront part 120 by means of thescrew 126 and on the other to therear part 121 by means of thescrew 127. - If the two parts are viewed together in the assembled state (see FIG. 14), it can be seen that the core15 substantially comprises an
upper plate 130 and alower plate 131, which are joined to one another, viaspacers screws 145. Therollers 71′-75′ (and behind them and therefore not visible, the rollers 71-75) are then disposed between the plates. - Both on the
upper plate 130 and on thelower plate 131, twofurther plates front part 120 and the rear part 121), these further plates being parallel and perpendicular to theplates underside 51′-55′. - FIG. 16 shows a further exemplary embodiment of modular construction, in which all the rollers are disposed inside a
boxlike frame 230, which comprises twoframe portions angle brackets 233. Theshaft 234 protrudes from theframe 230 at the bottom. It corresponds to theshaft 84 in FIG. 8 and FIG. 8a and is connected to a drive motor, not shown in FIG. 16. Within the module, the core is also fixed in the axial direction between the rollers. Aguide baffle 236 that is adjustable by means of screws is disposed on the frame, and thepaper tube web 8 can be delivered via itsguide face 237. The paper tube web is drawn across the mushroom-shapedinlet head 238 and opened out in the process and pulled through between the rollers. - As seen from FIGS. 20 and 23, the
shaft 234 carries theouter roller 241 and, via the twobevel gears shaft 303 and thus also theroller 251. Theshaft 303, via the bevel gears 304, 305, then drives theshaft 306 and thus also theroller 241′. Theshaft 234 moreover, via thebevel gear 307 and thebevel gear 308, drives theshaft 309, on which theroller 251 is seated. Therollers rollers internal tube 310, which is part of thecore 235, that when theshaft 234 is driven, apaper tube web 8 is pulled through, between the outer rollers and the inner rollers. Therollers rollers - Seated on the shaft303 (FIG. 20) on one side (to the right) of the
roller 251 is thegear wheel 311, and on the other is thegear wheel 312. - The
gear wheel 311, via a chain or pulley (not shown), drives thegear wheel 313 on the shaft 314 (see FIG. 21). Theshaft 314 carries thebevel gears bevel gears shafts rollers rollers paper tube web 8 can be drawn in and pulled through. - The gear wheel312 (FIG. 20), via a chain or a pulley (not shown), drives the gear wheel 325 (see FIG. 22), on which the
shaft 326 that carries theroller 252 is seated. Via the bevel gears 327, 328, 329, 330, theshaft 326 drives theshafts rollers shaft 331 is abevel gear 332, which drives abevel gear 333. The latter drives theshaft 334 and thus theroller 252′. - In this exemplary embodiment, the
rollers internal tube 310. To bring about the crumpling of the tube passing between these rollers on the one hand and theinternal tube 310 on the other and already crumpled and now radially compressed, and to improve this crumpling and at the same time to reinforce the feeding of the tube in the transport direction T, therollers pins 335 distributed at regular intervals along their circumference. - The shafts are each in
bearings 359 that are provided in gibs 350-357 (see FIG. 17). The gibs are screwed to theframe portions - Thus a
paper web tube 8 is drawn manually onto thecore 235 in the transport direction T at the beginning of the procedure, placed between therollers rollers rollers rollers outer rollers inner rollers outer rollers inner rollers - The different speeds of the first and second groups of rollers is due to the fact that the gear ratio of the gear wheel311 (FIG. 20) to the
gear wheel 313 is designed accordingly. - A further crumpling then takes place upon the reduction in the radial spacing (relative to the center line of the internal tube310) of the paper web tube as it is transported from this second group of rollers to the third group of rollers, formed by the
rollers outer rollers - It should furthermore be noted that the inner rollers are supported on the
internal tube 310 because suitablyU-shaped bearing brackets 360 are screwed onto the internal tube (FIGS. 20, 21). - To brake outer rollers of the first group of rollers, or —more precisely—the driven
outer rollers brake wheel 361, fixed in a groove 363 by atongue 362, is disposed on the shaft 320 (FIG. 21). Thebrake wheel 361 can, as seen from FIG. 24, be brought to a standstill by abrake belt 365, when theelectric motor 366 is excited. Then thearmature 367, on which the retainingrod 368 is secured with thebrake belt 365, is drawn inward by approximately 2 mm in the direction of the arrow. This tenses thebrake belt 365 and stops the motion of theshaft 320. As a consequence of the geared connection via bevel gears and shafts, this stop then causes a corresponding stop of theouter rollers - So that despite the aforementioned stop, the driven
rollers shaft 303 via thegear wheel 311 and pulleys, is supported on theshaft 314 by means of aslip coupling 370, which is shown in further detail in FIG. 25. This slip coupling makes it possible for the second group of rollers to continue rotating while the first group is stopped. The paper web tube then tears. - The slip coupling functions as follows: The
roller 250 is supported on theshaft 314 in thegroove 369 by means of thetongue 369′. Thegear wheel 313 rests laterally on theroller 250 but is not solidly connected to it. Inside thegear wheel 313, there is afurther gear wheel 371, whose left-hand shoulder 371′ is seated on an associatedshoulder face 313′ of thegear wheel 313. Thegear wheel 371 is coupled in the direction of rotation to theshaft 314 by thetongue 372 also engaging thegroove 369 and is pressed from right to left (in FIG. 25) into contact against thegear wheel 313. An adjustingscrew 374 is screwed into arecess 373, provided with afemale thread 373′, in thegear wheel 371. The adjusting screw, with itsouter shoulder 374′, presses against thecup spring 375, which in turn, with itsouter leg 375′ bent over inward, exerts pressure on thegear wheel 313. The adjustingscrew 373 is fixed in the axial direction because it is screwed onto a male thread of thetubule 376, which is disposed fixedly on theshaft 374 by means of a pin 377. In other words, the farther the adjustingscrew 374 is screwed inward (to the left in FIG. 25), the harder thecup spring 375 with itsleg 375 presses on the end face of thegear wheel 313. As a result, theshaft 314 is coupled frictionally to thegear wheel 313. However, the coupling is dimensioned such that whenever—as described—theshaft 314 is brought to a stop, thegear wheel 313, overcoming this friction, can rotate further. The adjustingscrew 374 can be adjusted from outside by the engagement of a suitable pin with one of the transverse bores 378. - The braking device, comprising
electromagnet 366 andbrake belt 365, is connected to asupport plate 380, which is screwed to the frame portion 232 (see FIG. 26).
