Definitions

  • the invention relates to an arrangement for superimposing two and more flat workpieces stacked in magazine stations designed as lifting tables in a predetermined mutual position on the laying table of a depositing station with the aid of a device for separating stacked workpieces and of traversing means for successively removing the workpieces from the Magazine stations and for positioned storage on the laying table of the storage station.
  • the invention has for its object to provide a further solution for an arrangement for the automatic folding of flat workpieces of the type described in the introduction, which manages during transition from one batch of workpieces to another batch of workpieces of different sizes and shapes with extremely short changeover times and thus the use of such arrangements, particularly in the manufacture of ready-made clothing, is significantly increased in their efficiency.
  • the invention is based on the essential finding that when a workpiece is separated from the workpiece stack, it is entirely sufficient to lift the workpiece to be separated on one side, in order then to use this opening gap to pull this workpiece by means of a film-like carrier with a slidable surface texture, for example a Teflon film, which may be tensioned between the workpiece to be separated and the workpiece stack from the workpiece stack sort of peel it off.
  • a film-like carrier with a slidable surface texture for example a Teflon film
  • separating devices such as are described, for example, in the cited reference DE 33364226 A1
  • a workpiece is separated from the workpiece stack by completely lifting this workpiece with the aid of a larger number of workpiece grippers, which grip the workpiece evenly on the circumference and in the central region of this workpiece.
  • most of the workpiece grippers usually have to be realigned with regard to the contour surface now available, which is time-consuming .
  • the simple reciprocating movement of the carrier between the magazine stations and the depositing station enables a depositing process to be carried out much more quickly than is possible with a conventional lifting device attached to a carriage.
  • the single figure shown in the drawing shows a perspective view of a preferred embodiment of the arrangement according to the invention with two magazine stations and a storage station, which are arranged in a row one behind the other.
  • a and B represent two magazine stations and C the storage station.
  • Each of the magazine stations A and B has a lifting table 1 with a spindle gear 2 for height adjustment, on each of which there is a workpiece stack 3 with three partial stacks 31, 32 and 33.
  • the partial stacks 31, 32 and 33 are each arranged one above the other in terms of their size such that the smallest partial stack 33 is the uppermost partial stack.
  • the magazine stations A and B have a separating device above the lifting table 1 and above the workpiece stacks 3 placed thereon.
  • This separating device 4 consists of a lifting plate 6 which is adjustable in the vertical direction on a lifting cylinder 5 and on the underside of which finger-shaped workpiece grippers 61, 62 and 63 are arranged.
  • the workpiece grippers 61, 62 and 63 are arranged on the lifting plate 6 so that they are aligned along the edge of the workpieces of the workpiece stack 3 on the side of the storage station C.
  • the spindle drive 2 of the magazine stations A and B is controlled in each case by a light switch 7 so that the uppermost workpiece of the workpiece stack 3 is always in a predetermined removal level regardless of the height of the workpiece stack.
  • two blowing nozzles 8 are also provided on the rear of the lifting table 1 of the magazine stations A and B, the air flow of which supports the separation process when carrying out a separation of a workpiece from the workpiece stack 3.
  • the partial stacks 31, 32 and 33 are stacked one above the other in such a way that they each abut together with a contour edge on the stop 9 in the form of a strip at the rear edge of the lifting table 1.
  • the workpiece gripper 63 which is furthest away from this stop 9, is adjustably arranged on the lifting plate 6 via a drive 63a.
  • a light sensor 63b is additionally assigned to the workpiece gripper 63 for controlling the drive 63a net, which causes a shift of the workpiece gripper 63 forward when changing from one partial stack to the next until its light beam directed downward onto the workpiece stack 3 is reflected.
  • each of the partial stacks 31, 32 and 33 is covered from above with a template 31a or 32a which is adapted to the contour surface of the workpieces of this partial stack and which has a light-reflecting partial surface 30 in on its top side below the adjustable workpiece gripper 63 Has the shape of a glued reflective film.
  • the uppermost partial stack 33 which has already been partially processed, understandably does not show the template originally covering this partial stack 33.
  • the storage station C has a conveyor belt 10 as a storage table, which is oriented perpendicular to the row of stations in its conveying direction.
  • a sliding frame 12 is fastened in the vertical direction on a mounting frame, not shown, to the lifting cylinders 11 above the conveyor belt 10.
  • three light sensors 13 are fixedly mounted in a suitable mutual arrangement on this mounting frame for controlling the positioning of the workpieces to be placed on the conveyor belt, the light beam of which is oriented downward onto the laying table.
  • the sliding frame 12 also has drives 14 and 15 controlled by the light sensors 13 for its sliding movement in the direction of the row of stations arranged one behind the other and in the direction perpendicular thereto.
  • an endless drive belt 17 guided over deflection rollers 16 is provided on each side. Both drive belts 17 are moved together by a drive 19 via a shaft 18 connecting the deflection rollers 16. Between these two drive belts 17, brackets 20 of the carrier 21 span the entire width of the stations, specifically in the removal plane in the area of the magazine sta tion A and B fixing height. In this way, the film-like carrier 21 can be moved between the different stations. It has the light-reflecting partial surfaces 21a, 21b and 21c required for the control of the drives 14 and 15 of the sliding frame 12 by the light sensors 13, which are in their travel position above the conveyor belt 10 in the region of the light beams of these light sensors 13.
  • the workpiece stack 3 on the magazine station A consists of jacket outer fabric parts which have been cut in the usual way so that the same fabric sides lie on top of one another in the case of successive workpieces in the stack.
  • the same is said to apply to the workpiece stack 3 on the magazine station B, which consists of inserts corresponding to the outer material parts on the magazine station A.
  • the template covering the uppermost partial stack 33, on the light-reflecting partial surface of which the light scanner 63b of the workpiece gripper 63 has been oriented for controlling the setting of this workpiece gripper, has already been removed on both magazine stations A and B.
  • the now uppermost workpiece on the partial stack 33 lies on the magazine station A with its outside of the fabric facing downward and on the magazine station B with its side having the adhesive dot grid facing upward.
  • the carrier 21 is now moved over the magazine station B to the magazine station A.
  • the uppermost workpiece is gripped and lowered on the workpiece stack 3 by lowering the lifting plate 6 with its workpiece grippers 61, 62 and 63 gripped edge with simultaneous activation of the blowing nozzles 8 by re-raising the lifting plate 6, an opening slot is created between this workpiece and the workpiece stack for the carrier 21.
  • the carrier 21 moves into this opening slot up to its end position above the magazine station A and thereby peels off this workpiece from the workpiece stack.
  • the lifting plate 6 with the workpiece grippers 61, 62 and 63 moves down again.
  • the workpiece grippers 61, 62 and 63 are released from the workpiece under pressure on the peeled workpiece on the carrier 21.
  • the lifting plate 6 then moves upward again with the workpiece grippers 61, 62 and 63.
  • the carrier 21 then moves with the workpiece separated from the workpiece stack 3 into its end position on the right-hand side above the conveyor belt 10 of the storage station C.
  • the sliding frame 12 lowers onto the workpiece and depending on the control of the light scanners 13, in cooperation with the light-reflecting partial surfaces 21a, 21b and 21c, it moves into the predetermined position.
  • the lifting plate 6 of the magazine station B lowers with its workpiece grippers 61, 62 and 63 onto the workpiece stack 3 which represents the insert parts and then lifts the uppermost workpiece on the side of the storage station C with simultaneous action of the blowing air of the blowing nozzles 8.
  • the carrier 21 By moving the carrier 21 towards the magazine station B again, the workpiece held on the underside of the sliding frame is stripped from the carrier 21 and placed on the conveyor belt 10 in the held position.
  • the sliding frame 12 then moves back into its raised starting position.
  • the carrier 21 in turn moves into the slot opening between the raised workpiece and the rest of the workpiece stack 3 and now peels off this workpiece, which represents an insert part, from the workpiece stack 3.
  • the carrier 21 moves the workpiece again over the conveyor belt 10 of the storage station C and play with the sliding frame 12 begins anew.
  • the insert 21 is then used to first pick up an insert part from the workpiece stack 3 of the magazine station B and finally a workpiece from the magazine station A and in the predetermined position in each case is deposited exactly over the workpiece underneath.
  • the sandwich that has been folded in this way is now, while the carrier 21 is again traveling to the magazine station A, to bring the first workpiece for the folding of another sandwich, via the conveyor belt 10 to the next processing station, which can be a hand station, for example, for further laying work to make this sandwich.
  • the adjustable workpiece gripper 33 orients itself on the template 32a in connection with the light-reflecting partial surface 30 on the new partial stack 32 in such a way that it is displaced in the forward direction as long until the light scanner receives its own reflected light.
  • the templates are then removed in the same way as the workpieces, placed on top of each other on the conveyor belt and then removed at the next work station.
  • the finger-shaped workpiece grippers 61, 62 and 63 are expediently designed as adhesive tape pickups, as are described in detail in the literature reference DE 3336426 A1.
  • the film-like carrier 21 can be designed quite differently.
  • a stretched film for example a Teflon film, it can also consist of a thin steel sheet or a thin elastic single or multi-layer plastic plate.
  • the conveyor belt 10 is aligned perpendicular to the direction of travel of the film-like carrier 21.
  • the arrangement of the conveyor belt can also be carried out so that its conveying direction is in the direction of travel of the carrier 21.
  • the arrangement according to the invention can advantageously be used wherever flat in the course of manufacture Workpieces are to be stored automatically one above the other and when processing batches of different sizes and shapes in small numbers, particularly short machine changeover times are important for the efficient use of such arrangements.
  • the preferred area of application is the production of men's and women's outer clothing.
