Definitions

  • the invention relates to a fabric laying machine with a laying table and a laying carriage that can be moved over it.
  • Fabric laying machines are known in various designs.
  • the laying trolley places one or more panels on the laying table, which are then further processed as a stack, in particular cut.
  • tearing devices for thread-appropriate separation of sections of one or more panels. These tearing devices are usually independent units.
  • the object of the invention is to equip a fabric laying machine with a tearing device, the tearing device not intended to disrupt the mechanics of the fabric laying machine and in particular also to be able to be subsequently integrated into a fabric laying machine.
  • the laying table has a cutout, that in the cutout a tearing device for thread-appropriate separation of sections of the fabric web laid on the laying table is arranged and that the tearing device has a carriage which can be moved telescopically beyond the cutout.
  • the ripper is preferably below the table level swiveling.
  • the tearing device can in particular have a carriage which is known per se and is guided on rails and which, as an abutment for tearing open the fabric webs and for guiding the fabric edges separated from one another, carries two double-tapered rollers arranged next to one another. Holding devices which hold the fabric web when tearing are expediently arranged on both sides of the slide and on the tearing device.
  • a preferred embodiment of the invention is characterized in that the rails of the tearing device are connected at their ends to a frame by means of cross members and that the frame in the tearing device is displaceable in the longitudinal direction of the rails, the cross members forming stops for the slide. Then the length of the ripping device can be smaller than the width of the laying table or the length of the cutout in the laying table, and the slide of the ripping device can still be moved beyond the broad sides of the laying table. Accordingly, webs of fabric can be torn that extend across the full width of the table or that stretch when torn. On the other hand, the tearing device can be kept so compact and small that it is the wheels of the laying carriage and the mechanics of the table, especially in the side area the table is arranged, does not interfere.
  • the tearing device is expediently connected to at least one swivel arm mounted on the frame and is articulated on a lifting cylinder mounted on the frame.
  • the one or more swivel arms can be easily stored below the table.
  • the ripping device can be swung under the level of the laying table, so that it does not hinder the laying of the fabric on the laying table.
  • the carriage on the swiveling tearing device is expediently carried out in that the carriage is connected in an articulated manner to one end of a rocker, the other end of which is guided in a backdrop and that Swing arm is connected to a drivable chain or cable hoist guided over frame-fixed pulleys.
  • the link guide should preferably be designed such that the rocker is oriented substantially perpendicular to the slide track in the starting position of the tearing device and essentially parallel to the slide track in the end position of the tearing device.
  • the carriage can also be driven by means of a chain or cable pull from a drive motor fixed to the frame.
  • the drawing shows the laying table 1 of a fabric laying machine, which also includes a laying carriage (not shown) that can be moved over the laying table 1.
  • the laying table 1 is mounted on a frame 2.
  • the laying table 1 has a cutout 3 which ends in front of the table edges on which the wheels of the laying carriage run.
  • a tearing device 4 for thread-appropriate separation of sections of the fabric web 5 laid on a laying table is arranged such that the separated ends of the fabric webs 5 can fall into a chute 6 belonging to the section 3 (FIG. 5).
  • the tearing device 4 includes two supports 7, 8 arranged next to one another, which extend at a mutual distance in the direction of the cutout 3 and which are connected to one another at their ends.
  • the carrier 7 is attached to two swivel arms 9, which are mounted below the table 1 in fixed swivel bearings 10.
  • the other support 8 is supported in an articulated manner on a lifting cylinder 11, the other end of which is fixed and articulated at 12. By actuating the lifting cylinder 11, the tearing device 4 can be pivoted overall into the operating position shown in solid lines in FIG. 5 and also into an inactive position below the table 1.
  • a plurality of rollers 13 with a circumferential groove 14 are mounted at a distance from one another, and rails 15 engage in the circumferential grooves 14 and, in the embodiment shown, consist of rods with a circular cross section.
  • the axes of the rollers 13 are directed perpendicular to the plane of the table 1.
  • the two rails 15 are connected at their ends via cross members 16 to form a frame which is displaceable in the guidance of the rollers 13 such that the frame can be displaced beyond the width of the laying table 1 on at least one side.
  • a slide 17 is also guided on the rails 15, on the underside of which rollers 18 are supported with circumferential grooves 19, and in the embodiment shown, two rollers 18 engage on the inside of each of the rails 15, so that the slide 17 is guided in a stable manner.
  • the carriage 17 can be moved along the rails 15 and, if it hits one of the cross members 16, also together with the rails 15 connected in a frame-like manner.
  • two double tapered rollers 20 are arranged side by side, which form the actual tear device.
  • a holding device comprising a tab 21 which extends above and parallel to the top of the carrier 7 and 8 and one with the underside of the tab 21 cooperating and an opening in the support 7 or 8 through the lifting cylinder 22 is provided.
  • a cutting device (not shown) is located between the two double rollers 20.
  • a rocker 23 is used to drive the carriage 17 along the rail guide, one end of which engages the carriage 17 in an articulated manner and the other end of which is guided by a roller 24 in a link 25 (FIG. 1).
  • the rocker 23 is shown in the starting position of the carriage 17 with solid lines.
  • the rocker 23 extends essentially in the vertical direction.
  • the end position of the rocker 23 after the tearing process is also shown on the left side with dashed lines.
  • the rocker 23 is essentially in the horizontal position.
  • the backdrop 25 is designed such that the rocker, the upper end of which is articulated to the carriage 17, can perform a corresponding movement.
  • the end of the rocker 23 connected to the slide 17 extends with the slide 17 outside of the table 1 because the carriage 17 encountered the corresponding cross member 16 during its movement and took the frame made of rails 15 and cross members 16 with it during its movement.
  • the tearing device 4 it is now possible to design the tearing device 4 so that its length is less than the width of the laying table 1. Nevertheless, it is possible to move the slide 17 and in particular the double tapered rollers 20 beyond the table width in order to separate webs of material which cover the entire width of the laying table 1. Any mechanics of the fabric laying machine that may be arranged in the side area of the laying table are not disturbed by the tearing device. When placing fabric panels on the laying table 1, the tearing device can be swiveled under the laying table 1.
  • the ripping device 4 is therefore universally suitable for all conceivable designs of fabric laying machines. It can also be combined with a fabric laying machine.
