Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • a winding device of the type mentioned in the preamble in which the fastener strip with fasteners lying between two parallel, rigidly connected plates is fed to the winding device.
  • Axial grooves in the winding mandrel serve to hold the first roll against which the fastener strip is pressed by tangential guide jaws.
  • fastener strips are now usually manufactured, the fasteners of which have different lengths.
  • the known winding device now does not allow the parts guiding and holding the fastener strip to be adapted to the different lengths of the fasteners.
  • the longitudinal grooves of the winding mandrel do not ensure that the fastener strip is held firmly, so that faults can occur during winding.
  • the object of the present invention is therefore to provide a winding device for fastener strips which can be adapted to the different lengths of the fasteners by simple means.
  • the shaft arranged under the guide rails together with a movable guide rail makes it easy to process fasteners of various lengths hanging vertically on their heads.
  • the vertical arrangement of the fasteners then expediently results in the arrangement of the winding mandrel with an essentially vertical axis at the exit of the shaft.
  • a further adjustment of the device results from a support bar in the shaft, which is also arranged in a height-adjustable manner together with a rotatable support disk of the winding mandrel.
  • the winding mandrel is pivotally mounted on a bracket relative to the shaft in such a way that the fastener strip coming from the shaft meets the continuously increasing winding substantially tangentially.
  • the arrangement of two winding mandrels makes it possible to place the wound fastener roll on a conveyor belt while the next strip is being wound up. This results in a continuous winding process with high performance.
  • the holding device designed as a clamping lever, the fastener strip to be rolled is securely held on the winding mandrel, so that trouble-free winding is ensured.
  • the winding device 3 has a base frame 7, on which 8 parallel guide rails 9 and 10 are arranged on supports.
  • the guide rail 9 is firmly connected to the base frame 7, while the guide rail 10 is fastened to a hinge 11 which is connected to a rear wall 12 of the base frame 7.
  • a compressed air cylinder 13 is pivotally attached to the support 8, the piston rod 14 of which is connected to the guide rail 10 via a bracket 15.
  • Tab 15 is pressed in the drawn position in FIG. 2 against an adjustable stop screw 16.
  • the guide rails 9 and 10 which are provided with guide strips 17, form a gap 18 in which the fastener strip 4 on the heads 19 of the fasteners 5 hanging, slidably mounted.
  • a front wall 20 is arranged opposite the rear wall 12, which has a funnel-shaped bevel 21 in the direction of the guide rails 9, 10 and which, together with the rear wall 12, forms a shaft 22 which is closed at the bottom by a support strip 23.
  • This support bar 23 rests on screw pins 24, for the screw threads 25 of which are provided in the rear wall 12 in the height of mutually offset threaded holes 26 are. By screwing the screw pin 24 into one of the threaded bores 26, the support bar 23 can be adjusted in height so that it can be adapted to fasteners 5 of different lengths.
  • the support bar 23 is provided at its end facing the collator with a support element 27 which is mounted on the support bar 23 against the force of a leg spring 28 so as to be pivotable about a vertical axis.
  • a light barrier 29 is arranged in the vicinity of the inlet-side end of the guide rail 9 and an inductive proximity switch 30 is arranged on the rear wall 12 at the height of the shaft 22 (FIGS. 1 and 4).
  • FIG. 1 and 3 also show a conveyor member 31 for the fastener strip 4, the motor 32 of which is attached to a fork 33 connected to the base frame 7 so as to be pivotable about an axis 34-34.
  • the motor 32 is also articulated to a link 35 with a guide rail 10.
  • a brush wheel 36 which can be driven by motor 32 engages in a cutout 37 of guide rail 9 in such a way that the brush wheel can exert a feed force on the fastener strips 4 hanging in gap 18.
  • 1, 4 and 6 show a rocker arm 39 which is tiltably mounted on the base frame 7 about a horizontal axis 38-38 and to which the piston rod 40 of an air cylinder 41 pivotally mounted on the base frame 7 is articulated.
  • a support 42 is fastened to the base frame 7 and is provided with two adjusting screws 43 which cooperate with a bracket 44 connected to rocker arm 39 (FIG. 4).
  • a cam 45 is also connected to rocker arm 39, which cooperates with a switch 46 arranged on the base frame 7 (FIG. 6).
  • a pivot shaft 47 is mounted, which forms an axis 48-48 (see also Fig. 5).
  • swivel shaft 47 is connected to a swivel drive 49 operated by compressed air, which is provided with two compressed air cylinders 50 located opposite one another.
  • a pressure switch 51 is assigned to each compressed air cylinder 50.
  • the pivot shaft 47 carries a pivot lever 52 which has two bearing arms 53 directed in opposite directions.
  • the two winding mandrels 54 and 55 are arranged on these, which correspond completely in their construction, but are directed opposite one another with respect to their vertical orientation.
  • the winding mandrel 54 pointing to the left in FIG. 4 is therefore described in detail below; this description also applies analogously to the winding mandrel 55 pointing to the right.
  • a bracket 56 with a fork 57 is pivotally mounted on the bearing arm 53 about an axis 58-58.
  • a leg spring 59 is provided concentric to axis 58-58, which exerts a clockwise force on bracket 56 and presses it against a stop (not shown) (FIG. 5).
  • a friction wheel 61 which has a friction ring 62 and is fixedly connected to a pulley 63, is freely rotatably mounted on a pin 60 concentrically to axis 58-58.
  • FIG. 4 shows a bearing sleeve 64 connected to the bracket 56, in which the hollow shaft 65 is freely rotatable about an axis 66-66. At its lower end, shaft 65 is connected to a further pulley 67, which is coupled to pulley 63 via V-belts 68.
  • shaft 65 is connected to a winding cylinder 69, on which a support disk 70 is arranged so as to be vertically displaceable. It is clamped at the desired height by a clamping screw 71 on the winding cylinder 69, depending on the length of the fasteners.
  • the two end positions are drawn out in FIG. 4 and shown in dash-dot lines.
  • the support disk 70 is provided on its bearing surface with radial and circular grooves 72 which serve to hold the tips of the fasteners 5.
  • a clamping lever 73 is also provided (FIGS. 4 and 5), which on the winding cylinder 69 by one axis; 74-74 is pivotally mounted.
  • a claw 75 presses on the head 19 of a fastener 5.
  • a pinion 76 is fixedly connected to the clamping lever 73 and cooperates with a toothing 77. This toothing 77 is attached to the end of a shift rod 78 which is mounted in the hollow shaft 65 so as to be longitudinally displaceable.
  • switching rod 78 is connected to a coupling sleeve 79, in which the coupling pin 80 of a piston rod 81 engages in such a way that the switching rod 78 is carried along by the piston rod 81 in the axial direction, but the coupling sleeve 79 is freely rotatably mounted on the coupling pin 80.
  • Piston rod 81 can be actuated by a compressed air cylinder 82 which is fixedly connected to the console 56.
  • FIG. 1 Another holding device for the fastener strip 4 during the winding process is formed by a holding finger 83, which partially surrounds the winding cylinder 69 and is pivotally mounted on the bracket 56 by means of a bearing rod 84 about an axis 85-85 parallel to the axis 66-66.
  • a leg spring 86 acts on the bearing rod 84 and exerts a force on the holding finger 83 in the direction of the winding cylinder 69.
  • An actuating cam 87 is fastened to the end of the bearing rod 84 opposite the holding finger 83, the piston rod 88 acts on a compressed air cylinder 39, which is also on the 56 is attached.
  • a cam 96 is provided at the end of the shaft 65, which cooperates with a proximity switch 97 attached to the bracket 56.
  • a motor 98 arranged on the base frame 7 is used to drive the winding cylinder 69 and is formed by a rotating field magnet in the present exemplary embodiment.
  • an angle lever 99 is pivotally mounted on the base frame 7, on the free end of which a pulley 100 and a mating wheel 101 connected to the friction wheel 61 are freely rotatable.
  • Pulley 100 is connected to the pulley 103 of motor 98 via a V-belt 102.
  • a compression spring 104 which is supported against the base frame 7, exerts a clockwise force on the angle lever 99 (FIG. 5).
  • a conveyor belt 105 can be provided according to FIG. 1, which takes over the completely wound fastener strip rolls 106 from the winding mandrel 55 and feeds them to a packaging station.
  • the fastener strip 4 manufactured in the collator and already cut to the desired length is guided in the output rail 1 and pushed through the conveyor chain 2 into the gap 18 between the guide rails 9 and 10 of the winding device 3.
  • the light barrier 29 is influenced by the fastener strip 4 and the conveyor 31 is thus switched on.
  • the brush wheel 36 of the conveyor 31 takes over the promotion of the fastener strip 4 until its end passes the light barrier 29, the conveyor 31 being switched off.
  • the displacement of the fastener strip 4 by the conveyor member 31 is accelerated compared to the displacement movement of the conveyor chain 2.
  • the light barrier 29 actuates the compressed air cylinder 13, which folds the guide rail 10 away from the gap 18 in such a way that the fastener strip 4 falls into the shaft 22 over its entire length and stands on the support bar 23 with its tips.
  • a delay device not shown, causes the guide rail 10 to be folded back into its holding position, the time gained by the acceleration of the fastener strip 4 by the conveying member 31 allowing the guide rail 10 to be opened without affecting the continuous output of the collator.
  • the fastener strip 4 arriving in the shaft 22 influences an inductive proximity switch 30, which causes rocker arm 39 to be pivoted into the extended winding position by compressed air cylinder 41 from the unloading position shown in broken lines in FIG. From Fig. 5 it can be seen that the support disk 70 of the mandrel 54 is pushed under the beginning of the fastener strip 4 and thereby the support element 27 swings away from fastener strip 4. By means of the rear adjusting screw 43 (FIG. 6), the winding mandrel 54 is pivoted so far that the first fastener 5 of the fastener strip 4 lies against the winding cylinder 69.
  • the holding finger 83 is actuated by the compressed air cylinder 89 via the bearing rod 84 and adapts with pre-tension to the increasing diameter of the fastener strip roll.
  • the winding mandrel 54 is arranged on the bearing arm 53 so as to be pivotable about the axis 58-58 against the action of the leg spring 49 and is pivoted counterclockwise during the winding-up process by the compressed air actuated lever 90 (FIG. 5).
  • the completion of the winding process is indicated by the proximity switch 30, which has passed the end of fastener strips 4. He controls cylinder 41 so that rocker arm 39 and thus the mandrels 54 and 55 are tilted into the unloading position. The friction wheel 61 moves away from the counter wheel 101 and the rotation of the winding mandrel 54 is ended. At the same time, the swivel drive 49 is actuated so that it swivels the swivel lever 52 through the swivel shaft 47 by 180 °.
  • the winding mandrel 54 thus comes into the position of the winding mandrel 55, in which the fastener strip roller 106 is held on the support disk 70 with the tips of the fasteners 5 upward by the clamping lever 73 and the holding finger 83.
  • the clamping lever 73 is pivoted in the winding mandrel 55 into the position shown in broken lines, so that the fastener roller 106 can fall down onto the conveyor belt 105.
  • control is advantageously carried out in a combined electrical-pneumatic manner.
  • the fastener strips 4 to be processed trigger the individual functions; the pivoting of the pivoting lever 52 is triggered by a pneumatic counting circuit.
  • the height of the support bar 23 can be adjusted by screwing the threaded pin 24 into corresponding threaded holes 26 in the rear wall 12.
  • the support surface of the support bar 23 can then be adapted to the support surface of the support disk 70 by moving it on the winding cylinder 69 to the desired height and clamping it by means of a clamping screw 71.
