Definitions

  • the invention relates to a method and a device for separating strands attached to eyelets on mounting rails are lined up in a stack.
  • EP 0 448 957 describes a device of the type mentioned known, in which the strands suspended on mounting rails laterally from a plane formed by the mounting rails deflected in one area and deformed elastically become. Then this is laterally deflected Area, in a direction inclined to the named plane, moved along a path from the stack until this path into the called plane penetrates and the lateral deformation of the Strand is lifted again. Because by the movement of the Area along the above-mentioned path, the strand also from her own, e.g. partially defined by the eyelets is deflected, further areas of the strand follow with a delay to. For example, the eyelets on the Guideways from the stack later than the laterally deflected Area.
  • EP 0 646 668 A1 is identical to this constructed device. With this device can a separation process is carried out in which in each case the foremost strand of a stack is separated and closed a transport unit - for example one with Locating pins for the endless belt provided - moved becomes. The first step is to separate the strands from the stack the foremost strand deflected. Then will the strand over the entire transport route to the endless belt thereby moving in the direction of transport that one or more Means of transport in the area between the two eyes of the Strand against the latter in one - with respect to one to the Support rails - press in an inclined direction.
  • the invention as characterized in the claims is now to solve the task, one method and one To create device that the strands when disconnecting and Handle subsequent transport away from the stack carefully and use as little as possible, especially for friction.
  • the device according to the invention can therefore be a Separating knife designed to separate the foremost ones Strand from the stack, a stack pusher to push back of the stack and a separating finger, for separating the Have strand from the stack over a large part of its length. Furthermore, it can have a transport member which in Areas of the eyelets of the strands is arranged. It is here preferred if the transport member also to support the Carrier rails are designed against gravity.
  • the advantages achieved by the invention are particular to see that all types of strands are reliable can be separated without being damaged and scratched. This is achieved by the strand being separated makes no movement relative to the cutting knife.
  • the drive of the separating knife and the stacking press can be set control so that only one common drive can be provided for both elements, what corresponding Cost savings as well as a less expensive device guaranteed. As little friction as possible between the Strands and the separation device occurs, the wear remains Small even for a long time.
  • the inventive Device is also suitable, at least standing next to each other twice, for at least two Stack to be run. You can do different movements run in a coordinated manner and accordingly also common Drives are provided.
  • Fig. 1 shows part of a drawing device for warp threads in strands and especially that part that is severing the strands from a pile.
  • Two stacks 5, 6 of Stranded wires are next to one another with their upper and lower eyelets 7, 8 and essentially vertically on two mounting rails each 1 2, 3, 4 lined up.
  • Each stack 5, 6 is in one Areas 11 along the strands near the bottom Eyes 8 assigned a separation device 9, 10.
  • this area is exemplified by the position of the separation device 10 and the separating device 10 ', which only another possible position for the disconnector 10 marked, indicated. It can also be seen that a transport element for each stack 5, 6 in the area of the eyelets 8 12, 13 is arranged.
  • Such transport organs are everyone DIN rail 1, 2, 3, 4 - and thus also the upper eyelets 7 - assigned. Because the structure of the individual transport organs can preferably always be identical, are only in Fig. 1 the transport members 12, 13 of the lower mounting rails 2, 4 shown. In front of the stack 5, 6 there is also a double here executed separating finger 14 is provided, which is in Fig. 1st between the foremost strand 15, 16 and the one already disconnected Strand 17, 18 is located.
  • Fig. 2 shows the same elements as Fig. 1. A difference however, is that the strands already separated 17, 18 in the direction of transport or movement of the strands are located behind the transport member 12, 13. The transport or direction of movement of the strands is in this figure an arrow 19 indicated, which is parallel to the longitudinal extent the mounting rails run.
  • a transport member 12, 13 is shown enlarged, the line of sight of this representation versus the direction arrow 19 and in the direction of one of the two Support rails 2, 4 runs.
  • the transport member 12, 13 has two rotating bodies 20, 21, each about an axis of rotation 22, 23 are stationary.
  • the rotating bodies 20, 21 are each with a gear 24, 25 provided which are in engagement with each other stand.
  • the rotating body 21 has above and below the Support rail 2, 4 arranged support body 26, 27 while the rotating body 20 is provided with a driver 28 which is next to the mounting rail 2, 4.
  • Fig. 4 shows a transport member 12, 13 from above in a first Position.
  • the support body 26, 27 guide the mounting rail 2, 4 via a nose 29 and form a with a surface 30 Stop for a severed strand 31.
  • the driver 28 clears a passage for the strand 31.
  • FIG. 5 shows the transport member 12, 13 according to FIG. 4 in the same position, but with the strand 31 in an intermediate position at the stop on the surface 30 in front of the transport member 12, 13.
  • FIG. 6 shows the transport member 12, 13 according to FIG. 4 in one another position in which the driver 28 and the Support body 26, 27 are rotated by 90 °.
  • the strand 31 is in another position - with regard to their direction of transport - Arranged behind the transport member 12, 13.
  • Fig. 7 shows schematically the most important parts of the separation device 9, 10, namely the cutting knife 32, which in the direction of arrow 33 movably supported and also driven and the stacker 34, which is on a fixed axis 35 is rotatably mounted.
  • a guide 36 can also be seen for a stack 37, a spring-loaded control pin 45 and a backdrop 42. The position shown is the starting or Rest position in which the stack is in a recess 38 rests on the cutting knife 32.
  • Fig. 8 shows another position with partially extended Cutting knife 32, and one through the recess 38, in or parallel to a plane 62, deflected foremost strand 39 of the stack 37.
  • a fixedly arranged on the separating knife 32 Bolt 40 is located on a backdrop 41 on the stack presser 34th
  • Fig. 9 shows another position with extended Cutting knife 32, the bolt 40 continues on the backdrop 41 advanced and the stack 37 by a few millimeters is pushed back against the force of a spring 43. Thereby there is now a nose 44 of the stack presser 34 between the stack 37 and the partially separated strand 39th
  • Fig. 10 shows another position in which the cutting knife 32 is already on the way back and the batch pusher 34 via the extended control pin 45 through the backdrop 42 is recorded.
  • the backdrop 41 is no longer on the bolt 40 on.
  • the separating knife 32 has in particular the bolt 40, the recess 38 for the strands and the backdrop 42.
  • the backdrop 42 is inclined Run-up surface 42a, essentially to the cutting knife vertical side surface 42b and an end surface 42c.
  • Fig. 13 shows a section through the control pin 45, the is attached to the staple presser 34 so that it with the Backdrop 42 can cooperate on the cutting knife 32.
  • the Control pin 45 consists essentially of a crest 45a, a spring 45b arranged in the tip 45a and one Pen 45c.
  • FIG. 14 shows a drive for a separating finger 14, 14 ' with a rodless pneumatic cylinder 47, one Carriage 48 for the separating fingers 14, 14 'and a shock absorber 49.
  • the separating fingers 14, 14 ' are on the carriage 48 rotatably supported about axes 63, 63 '.
  • rollers 50, 50' are mounted on one stationary backdrop 51, 51 '. In the representation of 14, the lower end position 52 is shown.
  • the foremost strand in the stack can first, laterally, ie essentially, in an area 11 of the strand (see FIG. 1) that is adjacent to the eyelet 8, seen in the longitudinal direction of the strand horizontal and transverse to the mounting rails, touched, deflected and removed from the stack 5.
  • the foremost strand thus occupies an intermediate position in front of the stack, as can be seen for example from FIG. 11 for the strand 39.
  • the eyelet adjacent to the deflected area is also shifted on its mounting rail into a similar advanced intermediate position.
  • the strand 39 is essentially deflected in a plane 62 - which is oriented approximately vertically to the mounting rails (cf. FIG.
  • the above processes in connection with the device will be described in more detail below:
  • the strands are lined up on their rails on mounting rails 1, 2, 3, 4 to stacks 5, 6.
  • the stacks are each acted upon from behind by a spring 43 (FIG. 9) in the direction of transport of the strands and are ready for separation.
  • the separator 9, 10 comes into action.
  • the separating knife 32 has the position shown in FIG. 7, the stack 37 being in contact with the separating knife 32 in the recess 38.
  • the stack can rest against a separating finger 14 (FIG. 1) which is in its upper end position 54 (FIG. 14).
  • the separating knife 32 begins to deflect the foremost strand 39 in the stack laterally in its plane 62 and the bolt 40 slides along the pusher 34 on the link 41. If the bolt 40 has reached a more inclined part of the link 41, the stack pusher 34 swivels faster against the stack 37 and pushes it back by a few millimeters. As the stack presser 34 pushes back the stack 37, the pin 45c (FIG. 13) of the control pin 45 runs on the inclined part 42a of the link 42, compresses in the process and springs out again beyond the vertical part 42b when the stack presser 34 pushes the in 10 has reached the position shown. The stack 37 is thus retained. This can also be seen from FIG. 9.
  • the separating finger 14 was also moved into its lower end position 52 and swung in through the link 51. Then the cutting knife 32 begins its backward movement.
  • the control pin initially remains behind the part 42b of the link 42 and thus also holds the pusher 34 in this position, although the pin 40 no longer rests on the link 41.
  • the stack pusher 34 can move the strand 39 into the intermediate position shown in FIG. 11 under the force of a spring 46 (FIG. 10). If the separating finger 14 now returns to its upper end position 54, it also passes through its intermediate position 53, in which the separating finger 14 is again pivoted out completely.
  • the separating finger 14 engages in the areas 11 behind the strand 39 and also brings those areas of the strand into the intermediate position which may still lie on the stack. Only then has the heddle reached the entire length of the intermediate position shown in FIG. 1 for the heddles 17, 18, from which it is conveyed further by the transport members 12, 13.
  • This now means that the strand 31 according to FIG. 5 is carried along by the rotating bodies 20, 21 rotating in opposite directions, the mounting rail 2, 4 also always being guided and supported.
  • the strand 31 is first moved forward by the driver 28 and then also by sections 57 of the supporting bodies 26, 27.
  • the sections 58, then the sections 57 and 58 and finally only the sections 57 support the mounting rails 2, 4 upwards and downwards against gravity. Laterally, the support rails 2, 4 are mostly guided through the outer circumference 63 of the driver 28 and through a body 59 between the support bodies 26, 27.
  • a recess 60 (FIG. 6) is provided in the body 59 and in the support bodies 26, 27, in which the eyelet finds a passage. If the recess 60 is rotated against the mounting rail, the mounting rail is not laterally guided for a short time. However, the rotating bodies 20, 21 are rotated further via the position shown in FIG. 6 until a complete revolution has taken place and the position according to FIG. 4 is reached again. As a result, the stranded wire 31 is also moved further on the mounting rail by the section 57. Then the processes described begin again for another strand.
  • a controller a device according to the invention three simple movements coordinated with each other. It is the movement of the cutting knife 32, the movement of the carriage 48 and the Movement of the transport members 12, 13. Has the cutting knife 32 completed its movement, the movement of the Slide from its lower to its upper end position 54. Then the transport members 12, 13 perform a movement, which consists of a 360 ° rotation.
  • the drives can too be carried out very simply since the separating knife 32 and the carriage 48 a linear movement and the rotating body 20, 21 perform a rotary movement.
  • all parts the device is executed twice when the drive is common and arranged so that two stacks 5 and 6 also can be treated at the same time.
  • a common carriage 48 is also possible. It is also conceivable, the device just for one single batch to run.
