Definitions

  • the invention relates to a method and a device for cutting cut parts for clothing.
  • the document US 4,266,112 discloses a method for cutting cut parts for clothing, in which a fabric web is continuously conveyed in a plane in its longitudinal direction and in which, during the continuous conveying, the same cut parts are simultaneously cut in a program-controlled manner on two cutting regions of the fabric web.
  • the known method does not disclose a supply roll from which the fabric web is unwound, no different cuts of the two cutting heads, and no mechanical or pneumatic removal of the cut parts.
  • the known device contains no supply roll, no waste roll, no removal device and no control unit for controlling the cutting devices on the basis of cutting programs.
  • no control functions are disclosed to the effect that the movement path of a removal device is controlled with respect to the conveying speed of the conveyor belt and that the cutting areas of adjacent cutting devices are kept separate from one another by a programmed safety area.
  • the known device is inflexible, it merely duplicates the cutting and facilitates the production of larger series.
  • the invention has for its object to provide a method and an apparatus for cutting cut parts for clothing, with which even small batch sizes of cut parts can be produced quickly and accurately with little manufacturing effort per cut part.
  • the cutting areas are expediently kept permanently separated from one another in a program-controlled manner by a safety area.
  • the device With the method according to the invention and the device according to the invention, even small batch sizes of cut parts can be produced quickly and accurately with little manufacturing effort per cut part.
  • the device is highly flexible. For example, it enables several different cut parts to be manufactured in succession, which means that even small orders can be fulfilled economically. Furthermore, the exact position of each individual cut part is known and can be automatically deposited by the removal device in an assigned storage place. This enables the simultaneous production of cut parts from several orders.
  • the device expediently has a scanner for checking the fabric web, with which errors as well as patterns and repetitions in the fabric web can be recognized.
  • the conveyor belt preferably consists of a brush fleece. If necessary, pressing the fabric onto the conveyor belt can also be achieved with the aid of a suction channel arranged under the perforated conveyor belt.
  • the device for cutting cut parts for clothing has a cutting table 10 with a horizontal upper contact surface 12.
  • An endless conveyor belt 14 made of brush fleece extends along the support surface 12 and is guided by two upper deflection rollers 16 rotatably mounted near the end faces of the support surface 12 and two deflection rollers 18, 19 rotatably mounted in the lower region of the cutting table 10.
  • the conveyor belt 14 is continuously driven by the lower deflection roller 18 on the left in the figure, which in turn is driven by a belt drive motor 22.
  • a tension roller 20 above it In the vicinity of the lower right deflection roller 19 there is a tension roller 20 above it, which presses against the conveyor belt 14, whereby a desired tension in the conveyor belt 14 is achieved.
  • the conveying direction of the conveyor belt 14 is shown in the drawing by the arrow F.
  • the conveying plane is then formed by the upper horizontal run of the conveyor belt 14.
  • Each cutting device 34 consists of a U-shaped portal 26, which extends transversely across the conveying plane of the conveyor belt, the two legs 27 of which extend downward and are guided in the respective guide rails 24.
  • a longitudinal drive 28 is attached to one of the legs 27, with which the portal 26 can be moved on the guide rails 24 in the longitudinal direction of the cutting table 10.
  • a cross support 32 is guided on a traverse 30 located above the conveying plane and connecting the two legs 27 of the portal 26 and can be moved transversely to the conveying plane by means of a transverse drive 33.
  • a cutting head 37 is attached to the transverse support 32 and has a cutting knife 36 which is driven by a cutting drive 35.
  • the longitudinal drive 28, the transverse drive 33 and the cutting drive 35 are connected via lines 38 to a control device 40 attached to a stand 42 spanning the cutting table 10 transversely.
  • a front support frame 44 is arranged in front of the cutting table 10, in which a supply roll 46 of the fabric web 48 is rotatably and insertably mounted.
  • the axis of rotation of the supply roll 46 extends transversely to the cutting table 10.
  • a steam device 50 is arranged between the supply roll 46 and the cutting table 10, the upper side of which is essentially at the level of the conveying plane.
  • a rear support frame 52 In the conveying direction of the conveyor belt 14 behind the cutting device 10 is a rear support frame 52 is arranged, in which a waste roll 54 is rotatably and insertably mounted.
  • the axis of rotation of the waste roll 54 also extends transversely to the cutting table 10.
  • the waste roll 54 is connected to a drive, not shown, which rotates the waste roll 54 synchronously with the speed of the conveyor belt 14.
  • a suction lifter 56 is arranged above the conveying plane of the conveyor belt 14, the drive (not shown) of which, like the belt drive 22 and the drives 28, 33, 35 of the cutting devices, is connected to the control device 40.
  • the trajectories of the cutting device 34 for a plurality of sectional images are stored in programs in which the transport speeds of the conveyor belt 14 and the safety areas are also maintained.
  • the device for cutting cut pieces for clothing works as follows: Before the device is started up, the fabric web 48 is unwound from the supply roll 46, pulled over the conveying plane of the conveyor belt 14 and connected to the waste roll 54. The program for the cut image or for the cut images to be cut is then called up and the device is started. The desired sectional images are cut out of the material web 48 conveyed by the conveyor belt 14 in accordance with the programmed movement paths. The trajectories of the cutting devices 34 are stored in the control device 40 for a standing material web. Now to the to obtain the desired sectional images, the control device 40 subtracts the conveying speed of the conveyor belt 14 from the stored longitudinal speed of the respective portal 26.
  • the data of the conveying speed of the conveyor belt 14 are transferred to the control device 40 by the belt drive 22.
  • the exact position and type of each cut part is known to the control device 40 from the data of the sectional images stored in the control device 40 and the data of the conveying speed.
  • This enables the suction lifter 56, which is also controlled by the control device 40, to remove the cut sections from the fabric web 48 and to place them in assigned places in accordance with their type.
  • the rest of the fabric web 48 is wound up by the waste winder 54 which rotates in accordance with the conveying speed of the conveyor belt 14.
  • the movement of the cutting heads is controlled so that there can be no collision.
