Definitions

  • the present invention relates to a method for zigzag folding in loops of a continuously fed flexible band, in particular textile band, the incoming band being drawn in with a laying device which can be moved back and forth perpendicular to the direction of entry and being folded at the exit. Furthermore, the invention relates to a device for this.
  • Such a method and a corresponding device are already known from DE-PS 1 802 889.
  • the incoming tape is placed in loops around two parallel winding pins arranged at a distance from one another by means of the laying device.
  • These Winding pins are each retracted in the axial direction from the region of the movement path when the laying device is moved outward on them, and after the laying device has passed the winding pin, the winding pins return to their winding position during the outward movement.
  • there is still a relative movement perpendicular to the to-and-fro movement between the winding pins and the laying device so that the winding pins each hold the last loop and continue to press the loops previously laid.
  • a disadvantage of this known device are the winding pins on the left and right side, since their lowering must be precisely controlled so that the tape guide can describe an 8. This requires complex mechanics that are subject to considerable wear.
  • the laying device when the bandwidth is changed, the laying device must be replaced to adapt to the new bandwidth.
  • this known device is not well suited for laying inelastic tapes, since these tend to fly out of the device. As a result, the laying process must often be interrupted, and the strips can be damaged by the pins when the strip flies out.
  • the laying quality is not optimal with regard to the regularity of the loop laying.
  • the present invention is based on the object of avoiding the above disadvantages and to improve a method and a device of the type described in the introduction in such a way that a uniform laying quality is achieved while avoiding complex and susceptible control means and that in addition an adaptation to different bandwidths is possible without changing the laying device.
  • this is achieved in that the belt is drawn in between the laying device consisting of two co-rotating rollers, bearing against one of the rollers, and the rollers change their direction of rotation in each of the two opposite reversal points of the reciprocating movement in such a way that after a displacement movement on the right, turn the rollers to the left, and to the left with a shifting movement to the left, and the tape is ejected from the rear roller in the direction of displacement for folding.
  • the previously known winding pins can be dispensed with entirely, and it is no longer necessary for the tape guide to have to describe an 8 in its movement sequence, but only a reciprocating movement in one plane, so that expensive control means are hereby used can be completely eliminated.
  • the band is braked at the top and bottom before folding. This measure improves the uniformity of the wrinkling.
  • a tape laying machine 10 consists of a table top 11, which serves as a support.
  • the table top 11 is attached to a stand or frame 12.
  • a laying carriage 13 Above the table top 11, a laying carriage 13 is arranged so that it can be moved back and forth perpendicular to the direction of entry X of a belt 9, see FIGS. 2 and 3, see arrows Y in FIG its intended displaceability. The shift occurs only in one direction of the feed of the volume 9 vertical plane.
  • the guide linkage 14 is fastened with its two ends in jacks 15 which can be raised and lowered. These trestles 15 each stand on a plate 7 with threaded bores 8 through which adjusting spindles 16 run.
  • adjusting spindles 16 are rotatably supported in bearing plates 6 which are fastened to the frame 12.
  • the adjusting spindles 16 each have a drive wheel at the lower end, in the example shown a sprocket 17, which are driven together via a chain 18. This enables a uniform adjustment of the adjusting spindles 16.
  • the drive of the chain wheels 17 takes place in such a way that the plates 8 and the blocks 15 can be raised or lowered continuously with the rotation of the spindles 16 caused thereby.
  • the chain 18 can be driven by motor or by hand, for which purpose a hand knob 5 is then attached to the upper end of one of the spindles 16.
  • the laying carriage 13 has two parallel rollers 4 which are rotatably mounted about a vertical axis. Between the two peripheral surfaces of the rollers 4 there is a vertical guide gap for the band 9 to be laid, see FIGS. 2 and 3, in which the band runs in the direction of the arrow X.
  • the band 9 is in vertical, i.e. H. upright position.
  • the gap between the circumferential surfaces of the rollers 4 is dimensioned in such a way that the belt 9 is frictionally carried by the circumferential surface of one of the two rollers 4, see also FIG. 5.
  • the two rollers are driven in the same direction, the direction of rotation being dependent on the Direction of movement of the carriage 13.
  • FIGS. 2 and 3 This dependence is shown in FIGS. 2 and 3, according to which when the carriage is shifted to the left, see solid arrow Y, the rollers 4 turn clockwise, in accordance with the solid arrow W, and in the case of a shift to the right, in accordance with the dashed arrow Y, turn the rollers to the left, according to the dashed arrow W.
  • the belt 9 is drawn in by the rear roller 4 against which it rests and transported, ie pushed out. Due to the drive described above and the displacement of the roller 4, the tape 9 is laid in regular loops 9a, as is illustrated in FIGS. 2 and 3.
  • the change in the direction of rotation W of the rollers 4 takes place at the reversal point of the sliding movement of the carriage 13.
  • an absolutely uniform loop formation is achieved with only slight deviations in the loop length and width, so that the loop reversal points are practically on the same straight line parallel to the middle of the loop.
  • friction strips 44 with friction surfaces are arranged above and below the rollers over the entire length of the displacement path, which act as a brake on the belt ejection, so that, as shown in FIG. 5, the belt 9 is somewhat raised after passing through the roller gap.
  • the upper friction bar 44 is formed on the underside of a pressure bar 43.
  • an assignment of the roller circumferential surfaces to the friction surfaces of the friction strips 44 is such that the front edge of the friction strips tangentially touches the roller circumference.
  • the roles are preferably sufficient to the center line of the friction strips.
  • the width of the friction surfaces of the friction strips is preferably 10 to 12 mm.
  • the rollers 4 are designed to be variable in the width of their peripheral surface. This is useful for adapting to different bandwidths.
  • the rollers 4 are designed as so-called rod rollers. These consist of a lower fixed disc 30, on the circumference of which is displaced somewhat inwards at a uniform mutual distance, preferably five vertical rods 31 are fixedly arranged. The center points of the circular cross-section bars on a concentric circular disk '30. Above the fixed plate 30 are two equal disks 28, 29 arranged on the rods 31st Of these discs, the central disc 29 is slidably mounted on the rods 31 up and down. The three disks 28, 29, 30 are thus arranged coaxially to one another.
  • the disks 28, 29 cannot be changed in their mutual spacing, and a rod 32 runs through the center thereof, which is fastened to the middle disk 29 and runs through a bore in the disk 28.
  • the rod 32 is fastened at its upper end to a guide body 3 of the laying carriage 13, the guide body 3 being displaceable on the guide linkage 14 by z. B. has bushings through which the guide rod 14 extends. Since, as described at the beginning, the adjusting spindles 16 move the guide linkage downwards or upwards, this is done simultaneously by the rigid connection extension of the guide rod 14 with the disk 29 via the rod 32, a raising or lowering of the disk 29 with respect to the disk 30.
  • the peripheral surfaces of the disks 29, 30 represent the contact or driving surfaces for the belt 9, see FIG. 2, so that an adaptation of the effective driving surfaces to the respective bandwidth is possible, for both rollers 4 at the same time.
  • a limiting plate 35 which closes the gap between the two rollers 4 upwards and prevents the tape from migrating out.
  • This limiting plate 35 is adjustable in height together with the disks 29, for which purpose it is attached to a vertical rod 33 at its lower end which is connected at its upper end to the guide body 3, so that the limiting plate 35 has the same up and down movement performs like the disks 29.
  • two parallel, vertical guide rods 34 are arranged, between which the band 9 is inserted into the roller gap. The guide rods 34 run through the limiting plate 35, which is thus arranged displaceably on the rods 34.
  • the boundary plate 35 is concave on its sides corresponding to the circular path described by the rods 31 during the rotation of the rollers 4 and is dimensioned somewhat longer than the radius of the rollers 4, so that the outward corresponding to the circumferential surface of the rollers 4 widening roller gap is covered more than half of its length from above.
  • the upper pressure bar 43 is toothed.
  • the number of teeth depends on the number of bars on the bar rollers and their peripheral speed.
  • the teeth of the pressure bar 43 protrude approximately to just before the center of the roller and are preferably rounded at their edges and taper towards the tip on their underside.
  • the teeth are designed such that the rod rollers run with play in them. Since the pressure bar 43 is fastened with its ends to the plates 7, the pressure bar 43 rises and falls together with the disks 29. As can be seen from FIGS. 1 and 4, the pressure bar 43 is arranged directly above the disks 29.
  • the drive of the laying carriage 13 for its back and forth movement perpendicular to the feed direction X of the belt 9 takes place with a chain drive made of chain wheels 23, 24 and a chain 25.
  • the chain wheels 23, 24 are driven by a belt drive from pulleys 21, 22 and a V-belt 20 driven.
  • the pulley 21 is seated on the drive shaft of a motor 19, and the pulley 22 is connected to the chain wheel 23 via a shaft, see FIGS. 1 and 4.
  • a driver 26 is non-positively connected via a driver bolt attached to the chain 25 42 connected.
  • This driver pin 42 is guided to and fro in a guide groove 41 formed on the underside of the driver 26.
  • the driver 26 is oriented perpendicular to the two strands of the chain 25 and the guide groove 41 has a length which corresponds to the distance between the outer edges of the two strands.
  • the driver 26 consists of a U-profile, which is completed by a plate 36 above. On the underside of the plate 36 26 pairs of wheels 38 are arranged in front of and behind the driver, which are guided in a guide rail 37. This guide rail 37 runs below the plate 11 parallel to the guide linkage 14 and is connected at the end to the frame 12. As can be seen from FIG. 4, the guide rail 37 is surrounded by the driver 26 in the center. In the plate 36 axes 2 are rotatably mounted, at the upper end of the rollers 4 and the lower discs 30 are attached. The plate 11 has a slot 45 through which the axes 2 run in order to enable the back and forth movement of the laying carriage 13. The guide rods 34 are also fastened on the plate 36 and run through a second slot 46 in the plate 11 parallel to the slot 45. The driver 26, the plate 36 with the wheels 38 together form the lower part 27 of the laying carriage 13.
