Definitions

  • the invention relates to a method for banding goods, in which a section of a banding strip is pulled off a bobbin, held at its free end and pushed onto a loop by strip material conveyed by the bobbin, and in which the goods are then pushed into the open loop , then the loop around the goods is pulled tight to the banderole and connected at the ends and separated from the bobbin, and a device for carrying out this method.
  • the object of the invention is to design a method and a device of the type mentioned at the outset such that softer banding strip material can also be used in the interest of saving costs without fear of undesired collapse of the loop.
  • the stripping band provided is assigned a molding unit for embossing at least one longitudinal embossing or reinforcing fold in the banding strips.
  • the invention incorporates an additional dimensional stability into the strip shortly before the formation of the loop through the stiffening. This dimensional stability makes it possible to use less rigid strip material by nature than when using strip material without such stiffening.
  • the stiffening is preferably in the form of one or more longitudinal folds or preferably in the form of one or more longitudinal embossments. It has been shown that a noticeable additional stiffening can be achieved, even if such a longitudinal fold is unfolded again after folding. The subsequent unfolding makes it easier for the stiffened banding strip to be pushed onto the desired loop as easily as the unembossed banding strip and can also be pulled back tight.
  • the invention can be implemented by using banding strips which are wound from the outset with the stiffening onto the bobbin, from which they are then pulled off.
  • this requires appropriate precautions when manufacturing the bobbin.
  • the invention can also be implemented using bobbins, the banding strips of which are not stiffened.
  • the stiffener is then embossed after the banding strip has been pulled off the bobbin or while it is being pulled off.
  • a corresponding development of the inventive method is characterized in that for advancing of the banding strip is conveyed into the loop between two conveyor rollers so that the stiffening is molded directly upstream of these conveyor rollers or through these conveyor rollers.
  • the banding strip Since the banding strip has to be pulled tight around the goods inserted into the loop, it is first advanced in the feed direction when the loop is pushed open and then withdrawn in the retraction direction to pull the loop together.
  • the bobbin strip can be subjected to the stiffening again. Instead, however, it is advisable to stiffen the bobbin strip only when feeding and not also when pulling the bobbin strip back. How this can be implemented very easily in terms of the device is explained with reference to the attached drawing and is the subject of a further development.
  • a single reinforcement fold or longitudinal embossing is sufficient for stiffening, but it is also possible to provide several reinforcement folds or longitudinal embossments next to one another, with alternating or the same orientation.
  • Embossing is preferred as stiffening because it can be incorporated with a simply equipped molding unit and leads to a stiffened banding strip that is particularly easy to process.
  • a corresponding further development which is characterized by a simple design, is characterized in that the molding unit has two rollers arranged axially parallel to one another on both sides of the banding strip, opposite one another and rotatable in the feed direction of the banding strip, one of which is designed as an embossing roller and one or more are in one Has circumferential extending projecting hard embossing ribs and the other is designed as a counter-roller and an elastically resilient man tel and that preferably the two rollers are loaded by an elastic force indirectly roll on each other.
  • the two rollers of this molding unit can rotate freely with the solid banding strip. But they can also be driven.
  • This embodiment is preferred because it saves an additional pair of driving rollers or a pair of driving rollers can be replaced by the driven embossing roller and counter-roller.
  • This embodiment also has the advantage that it can easily be ensured that the banding strip stiffened by embossing is pushed on directly to the loop after the embossing has been carried out, that is to say is no longer wedged in, so that the embossed embossing remains undamaged until the loop is formed .
  • 1 denotes a rotatably mounted bobbin on which a flat banding strip 2 is wound.
  • the banding strip 2 is pulled off and pushed on to form a loop 3 drawn in solid lines.
  • the loop 3 extends over a table top 4 on which a product 5 to be banded is provided.
  • a turning bracket 8 can be pivoted about an axis perpendicular to the drawing plane of FIG. 1 by 180 ° and is displaceable in the drawing plane, each driven by a drive element 9.
  • the outermost free end of the banding strip 2 projects into a combination unit 10 driven by the drive element 20, which also includes a holding device for the banding strip, not shown in detail, a cutting knife for cutting off the banding strip and a welding device for connecting the free ends 26, 27 of the banding strip which has been pulled tight around the goods 5.
  • 11 and 13 denote two loose, rotatable, stationary guide rollers in the path of the banding strip 2, which are rotatably mounted about axes perpendicular to the drawing plane of FIG.
  • 12 and 14 two drive rollers are designated, which are movable and rotatable in the direction of the double arrow 15, each driven by the drive elements 16 and 17.
  • the drive roller 14 is brought into the position shown in which it the banding strip presses against the guide roller 13 and drives in the feed direction coinciding with the longitudinal direction of the banding strip 2 according to arrow 18.
  • the drive roller 14 or the drive element 17 is equipped with a braking unit, so that the banding strip can also be held stationary between the two rollers 13 and 14.
  • the banding device works as follows. First, the banding strip 2 is held at its free end by the turning clip 8 and pushed onto the loop 3 drawn in solid lines and then further to the loop 21 shown in broken lines so far that the ready-made goods 5 fit into the loop and can be inserted. The free end of the banding strip 2 is held in the combination unit 10. Then the turning clamp 8 releases the banding strip and swivels downward about 180 ° about an axis perpendicular to the plane of the drawing into the position shown in FIG. 2. Then the loop is pulled tight by the drive roller 12 and the resulting overhang of banding strips is wound onto the bobbin 1, which is coupled to a drive element 22 for this purpose. Now the turning clamp 8 again grips the banding strip in the position shown in FIG. 2 with an overhang at the free end of the new banding. Now, the combination unit 10 is used to weld and cut the banding 23, which is taut around the goods 5. The parts are now in the functional position shown in Figure 2.
  • the banded goods are removed and the turning clamp 8 moves back into the position shown in FIG. 1, rotating in the direction of arrow 24 by 180 °, so that a small loop is formed, which then advances to a new loop by advancing the drive roller 14 the loop 3 or 21 is pushed on.
  • a molding unit 25 is additionally provided, which is arranged between the guide rollers 11 and 13 on the path of the banding strip 2.
  • This molding unit forms a longitudinal stiffening of the banding strip when it is fed in the direction of arrow 18. The described stiffening does not impede the described function for forming the loop and for pulling the loop together, but the self-supporting loop 3 or 21 is prevented from collapsing.
  • the molding unit 25 When the loop is pulled together, a short section of the banding strip passes the molding unit 25 in the direction opposite the arrow direction 18 and then runs again for the new loop through the molding unit 25 again in the arrow direction 18.
  • the molding unit 25 is designed such that it can be passed through in both directions by the banding strip.
  • the molding unit 25 is stationary and immobile. Instead, an adjustable or movable molding unit can be provided which is cleared out of the way or has no function is made when an already folded banding strip passes.
  • FIG. 3 shows a modification of the exemplary embodiment according to FIGS. 1 and 2, in which the molding unit 35 corresponding to the molding unit 25 is arranged at a point at which the banding strip only passes in the feed direction according to arrow 36.
  • a guide roller corresponding to the guide roller 11 is designated, a drive roller corresponding to the drive roller 12 is not provided.
  • a guide roller corresponding to the guide roller 13 and with 41 the drive roller 14 corresponding drive roller is designated.
  • this drive roller 41 can be driven by the drive member 42 in both directions and cannot be lifted off.
  • a pair of terminals 38 that can be controlled by a drive element 40 is provided.
  • the banding tape is fed in exactly the same way as explained in the text for FIGS. 1 and 2 with the clamp 38 open, specifically under the feed drive of the drive roller 41.
  • the banding strip 43 is not rewound onto the bobbin 52 when pulled tight, but stored in a storage loop 53.
  • the clamp 38 is closed when withdrawn.
  • the clamp 38 only opens again when the loop 53 is pulled open during the feed. In this way it is ensured that the banding strip is only drawn in the direction of arrow 36 coinciding with the longitudinal direction and not in the opposite direction through the molding unit 35, since this is arranged upstream of the clamp 38.
  • Shaping units which are designed as folding units and one or more are explained with reference to FIGS. 4 and 5 Emboss longitudinal folds in the banding strips as shown in Figures 6 to 9.
  • the folding units according to FIGS. 4 and 5 can be used for the forming units 25 and 35 according to FIGS. 1 to 3.
  • stationary sliding surfaces 60, 61, 62, 63 are provided, of which the sliding surfaces 60, 61 are arranged below the banding strip 2 and the sliding surfaces 62, 63 above the banding strip.
  • the banding strip is pulled between the sliding surfaces.
  • the sliding surfaces have the shape of the banding strip 2 which is led to a simple folding, namely the sliding surfaces 60 and 62 in relation to the feed direction 18 and the sliding surfaces 61 and 63 in relation to the opposite direction.
  • the banding strip, which passes the folding unit in the feed direction 18, is thus folded between the sliding surfaces 60 and 62 to form a crease, which then opens again between the sliding surfaces 61 and 63.
  • the sliding surfaces are mirror-symmetrical to the mirror-symmetry plane 65, so that the folding of the banding strip, which runs in the opposite direction to the arrow 18, takes place or is repeated accordingly.
  • this can also be designed such that it impresses several folds 82, 83, 84, 88, 89, as can be seen, for example, from FIGS. 7 and 8.
  • 75 denotes a metal bracket which forms an elongated eyelet 73.
  • the free ends of the metal bracket 75 are attached to a round rod 77.
  • the round rod 77 is longitudinally displaceably mounted in a holder 79 in the direction of the double arrow 78 and can be fixed in the set height position by an external grub screw 80.
  • the length of the eyelet protruding from the holder 79 can therefore be adjusted by adjusting the round rod 77. It is set so that it corresponds to the width 81 of the folded banding strip 74 with a small tolerance allowance.
  • the banding strip 74 is inserted in a "V" shape into the eyelet 73 and folded in the process, and the folded edge is pressed in the eyelet.
  • two rolls are designated, which are arranged axially parallel to each other opposite to both sides of the web of the folded banding strip, like rolls 66 and 67, and roll on the folding edge 87 when the banding strip 74 is moved.
  • the folding edge 87 is pressed sharply.
  • the folding unit from FIG. 9, generally designated 90 can have sliding surfaces corresponding to sliding surfaces 60-63 from FIG. 4 or other sliding surfaces with a similar function be upstream or downstream. In this case, however, the sliding surfaces are oriented with respect to FIG. 4 with the underside uppermost, because according to FIG. 9 the folding edge 87, in contrast to FIG.
  • the exemplary embodiments according to FIG. 4 and FIG. 9 can be modified in the sense that in FIG. 4 the sliding surfaces can also be turned over so that the folded edge points upwards, and according to FIG. 9 the arrangement can also be modified so that the folded edge points downward points. In such a case, the rollers 85, 86 may have to be displaced so that they roll again on the folded edge.
  • the embossing unit has two rollers 102, 103 arranged opposite one another, axially parallel to one another, on both sides of the web of the banding strip 100. These rollers can be rotated in the feed direction 101 which coincides with the longitudinal direction of the banding strip 100.
  • One roller is designed as an embossing roller 102 and has a plurality of hard embossing ribs 104 to 106 which extend in the circumferential direction and, moreover, has a casing 107 made of hard material.
  • the embossing ribs are closed rings that extend around the entire circumference and protrude from the jacket 107.
  • the other roller is designed as a counter roller 103 and has an elastically resilient jacket 108.
  • the rotary bearings 109, 110 of the embossing roller 102 are stationary during the embossing operation.
  • the rotary bearings 111, 114 of the counter-roller 103 are pressed in the direction of the embossing roller 102 during the stamping operation under spring loading by the springs 112, 113.
  • the banding strip 100 moves in the direction of arrow 101 or when the loop is pulled together a short section in the opposite direction between the rollers 102, 103 and, as can be seen from FIG. 12, is provided with longitudinal embossments 115 to 117, which result in the desired stiffening of the banding strip.
  • the embossing begins along the dash-dotted line 118, so that an embossing is shown corresponding to the feed direction 101 only to the right of the dash-dotted line 118, but not to the left thereof, because an unembossed banding strip is fed to the embossing unit.
  • the two rollers 102, 103 can rotate loosely while the banding strip, pulled by the drive rollers 12 or 14 from FIG. 1, is pulled through the embossing device formed by the rollers.
  • one of these rollers preferably the embossing roller 102 or both rollers 102, 103, can also be driven in a rotating manner by a corresponding drive element 120, 121.
  • the drive elements 120, 121 are controlled synchronously with the drive elements 16 and 17 . The same applies correspondingly to the use of the embossing unit from FIGS. 10 and 11 in connection with the device according to FIG. 3.
  • embossing unit according to FIGS. 10 and 11 equipped with at least one driven roller instead of the drive roller 14 and the guide roller 13 from FIG.
  • the embossing roller 102 then additionally assumes the function of the drive roller 14 and is lifted in the direction of the arrow 15 and lowered into the functional position, while the counter roller 103 assumes the function of the guide roller 13.
  • a special molding unit 25 is then unnecessary because its function is performed by the rollers 102 and 103.
  • This configuration has the particular advantage that one saves gear elements and that once embossed banding strip is pushed onto the loop immediately after the embossing unit, so that once the stiffening is embossed, it is no longer reduced, as is the case when the embossing device is followed by a pair of drive rollers.
  • an embossing unit from FIGS. 10 and 11 equipped with at least one driven roller can also be used for the rollers 41 and 39 from FIG. The molding unit 35 is then no longer required. In this case too, transmission elements are saved.
  • the banding strip can consist of plastic film, paper or metal foil. It can consist of weldable material or be coated with a weldable or adhesive layer. It is essential for the invention that the stiffness of the banding strip required for the stability of the open loop, due to the stiffening, can be achieved with much thinner strip material and therefore with material savings.
