Definitions

  • the invention relates to a method and a device for compensating for the different speeds during the unwinding and feeding of packaging tape, which is unwound from a supply roll relatively slowly at long intervals and, after having passed through a compensating memory, is fed to a packaging machine at higher speeds at shorter intervals.
  • DE-PS 22 62 148 From DE-PS 22 62 148 a method and a device for storing steel strip in a roll are known. Large lengths of the tape are stored there in a large number of turns. If the winding serves as compensation by feeding and removing the tape at different speeds, the heavy winding must be rotated. Here, driven rollers serve as auxiliary drives. The method and the device described in DE-PS 22 62 148 are unsuitable if the tape has to be removed from the roll very quickly for short periods. Large inertia forces arise when the support table is jerked in rotation.
  • the strip is curved in a very narrow radius at the reversal points of the loops. If the packaging machine e.g. B. is not used for half an hour, so the sharp curvatures in the packaging tape. The appropriate piece of packaging tape must then be cut and discarded and the packaging machine memory must be filled with new meandering loops for reuse.
  • the invention is based on the objective 'to eliminate the disadvantages of recordings described and to create a storage that stores the packing tape without sharp bends and when the packing tape can be removed quickly and intermittently from the memory.
  • the packaging tape is stored during normal operation, with the exception of the initial state, in a winding, the roughly circular turns of which are loosely wrapped around one another with gaps, the supply at the innermost turn and the removal of the packaging tape the outermost turn is set at the latest when a calculated average value of the space to the adjacent turn, measured at 3 measuring points of a turn offset by 120 °, is less than the thickness of the packaging tape.
  • the packaging machine pulls off the packaging tape in jerks, only the few turns of the winding turn, which overall have a smaller diameter than before after the removal. Only packaging tape for one to five strapping is stored in the wrap. While the packaging tape is withdrawn from the store in jerks for only a very short time, the supply, on the other hand, takes place much more slowly and in a longer period of time. As is well known, this has the advantage that the heavy supply roll only has to rotate slowly, which is important because of the risk of accidents.
  • the packaging tape runs into the winding without stalling and without warping, it is advantageous that the packaging tape is fed to the innermost turn of the winding in an area which lies on a circular ring, the center of which coincides with the center of an outer ring falls and its largest and smallest radius Have 95% and 70% of the value that the radius of a limiting outer ring has, or that has the largest possible outer turn if the outer ring is missing.
  • the packaging tape is guided through a channel or other guide means up to the inner turn and is guided approximately tangentially into the innermost turn without guide means.
  • This eccentric arrangement of the windings of the winding also has the advantage that the packaging tape fed to the store does not have to be sharply curved.
  • a relatively large radius of curvature arises for the packaging tape when it is fed to the roll with the roll upright, somewhat above the lowest point of the roll, approximately parallel to the tangent to the lowest point of the roll. Due to the fact that the wrap rests at the lowest point due to the weight, the wrap has a certain stability there and also the only point where friction occurs. It is an advantage if the packaging tape is also pulled off at this point, because then the through The forces arising from friction cannot propagate up to the inner windings of the winding.
  • a device for carrying out the method consists of a storage device interposed between the supply roll and the packaging machine, which has a narrow, ring-shaped storage space that is slightly wider than the winding of packaging tape to be stored therein, and to which a guideway for feeding is attached is, which in the area of a circular ring opens approximately tangentially to the innermost turn formed in the operating state and in which the largest and smallest radius of this circular ring is between 95% and 70% of the radius that the bounding outer ring has or the largest in the absence of an outer ring has possible winding of the winding and that the center of this annulus coincides with the center of the outer ring or the outermost winding and in which at least one switch provided with a scanner of the windings of the winding is installed, which drives the packaging tape to the memory z ujoden transport device (pair of rollers) is connected, and the scanner is set so that the switch is in the on position of the drive when a preselected diameter of the innermost turn is reached and the switch is in the
  • the turns of the storage can be used very quickly for storing or releasing the packaging tape because only the small masses of the turns themselves have to be accelerated and almost no frictional forces occur.
  • the spring force of the packaging tape and the number of turns and the radius of the turns are coordinated so that the turns on most of their circumference do not touch and a free space remains.
  • a largely self-supporting winding is obtained especially when the windings of the winding lie in a vertical plane and are closer together in the vicinity of the lowest point of the winding than in the vicinity of the uppermost point.
  • the packaging tape 11 is usually pulled off a large supply roll 12 with the aid of the pair of rolls 13 driven by a motor. Behind the pair of rollers 13, the packaging tape 11 is pushed through the straight guide channel 14 and the curved guide path 15 into the store 16. Because of the pushing movement in the guide channel 14 and the guideway 15, only very low frictional forces may occur there. With stronger frictional forces, the packaging tape 11 would form and jam even in the straight guide channel 14.
  • the large radius of the guideway 15 ensures only low friction.
  • the packaging tape 11 is transported from the innermost turn 17 in a spiral, the center of which is shifted, to the outermost turn 19 of the winding 18.
  • the outermost turn 19 only bears against the outer ring 20 during the first filling process.
  • the outer ring 20 is closed in a ring shape when the reservoir 16 is filled for the first time and is rotatably mounted on the rollers or bearings 21 and 22.
  • the outer ring 20 rotates once for each stored turn. If there is a sufficient number of turns in the store 16 during the first filling, the outer ring 20 is opened at its lowest point at point 23, the ends being bent apart somewhat elastically and locked or hooked in the open position.
  • the beginning of the packaging belt 11 is guided on the way 24 and 25 to the driven roller pair 26 by the operator.
  • the additional packaging tape 11 is automatically removed from the memory 16 if required.
  • the pair of rollers 26 guides the packaging tape in a known manner through the strapping channel 28 around the package 27 to be strapped until the beginning reaches the closure head 29.
  • the drive of the pair of rollers 26 is controlled by the Versdalußkopf.
  • the pair of rollers 26 very quickly pulls the packaging tape 11 required for each strapping from the store 16. Then there is a pause until the next strapping.
  • the lower speed compared to the pair of rollers 26 is compensated for by the drive 13 running for a longer period of time. It is advantageous that the drive 13 runs only slowly because it has to set the large mass of the supply roll 12 in motion. With the exception of the first initial filling, an air gap is left between the outer ring 20 and the outermost turn 19 of the winding 18 during refilling during normal operation, so that no friction can occur between these parts. It is important that the removal of packaging tape 11 from the storage 16 can be done with relatively little force because the rollers 26 press against the packaging tape with little force.
  • This setting with low contact pressure of the rollers 26 is therefore chosen so that the rollers 26 on the packaging tape 11 can slide after the front edge of the packaging tape 11 has reached a stop in the closure head and the packaging tape 11 is suddenly braked.
  • the rollers 26 and their drive cannot be braked so suddenly, they still make a few revolutions to a standstill.
  • the drive 13 for the tape feed is controlled by the switch 30.
  • the switch 30 contains a scanner 32 designed as a lever, which is pressed laterally against the end faces of the windings with a slight spring force.
  • the winding 18 is shown in the switched-on position 38 and the switched-off position 37.
  • the switched-on position 38 the winding 18 presses the scanner 32, into the position 34 shown in broken lines, in which the switch-on contact 35 for the Drive of the rollers 13 is closed.
  • the scanner 32 is then in the position 33.
  • the scanner 32 is provided with a bevel 36, so that a smooth transition from the two extreme positions 34 and 38 is achieved.
  • the switch contact 35 is already closed when the innermost turn 17 touches the first third of the slope 36.
  • the diameter of the windings then continues to decrease despite the drive of the rollers 13 being switched on because the packaging tape 11 is pulled off more quickly by the rollers 26.
  • the winding 18 can therefore reach position 38.
  • a pause when e.g. B. a new package is introduced into the strapping machine only the drive of the rollers 13 acts, so that the off position 37 of the winding 18 is reached before the next strapping.
  • the scanner 32 can be replaced by a light beam which runs according to the slope 36 and when interrupted a photoelectric cell and a connected relay turn on the drive to the rollers 13.
  • a second monitoring switch 31 is also necessary, which then switches off when the front end of the packaging belt 11 has missed a stop by which the drive of the rollers 26 is switched off. It would be in one In such a case, the rollers 26 pull as much packaging tape 11 from the store 16 until the diameter of the winding 18 has become very small and all the turns lie firmly on one another and are practically jammed, so that the store 16 can no longer be refilled.
  • the switch 31 which is constructed like the switch 30, monitors with its sensing scanner a circular area within the winding 18, the diameter of which is even smaller than the diameter of the smallest turn that normally occurs during operation.
  • This switch 31 switches off the drive to the rollers 26 or the entire packaging machine when its scanner is pushed up by one turn.
  • the beginning of the packaging tape 11 can be bent by hand into a ring, the beginning of z. B. is fixed by adhesive tape.
  • Such a limiting ring is limited in diameter by at least three expedient to 120 0 slight offset rotatable rollers or bearings, said rollers or bearings for the rotation at the first filling care.
  • the described device for plastic packaging tape can also be used advantageously with steel tape packaging tape.
  • the axis of the winding can also be in a position other than horizontal z. B. also stand vertically.
