  • the invention relates to a device for picking up, transporting and precisely depositing flat workpieces, in particular fabric parts, from at least a first depositing point to a second depositing point, consisting of a moving or rotating platform bridging the depositing points and equipped with at least one lifting device, in which the lifting device working according to the adhesive principle of action also includes in the form of an adhesive tape pickup arrangement, in which the adhesive tape pickup arrangement also consists of an adhesive tape winding device which is longitudinally displaceable on a frame in a guided holder and has tape deflection rollers which are provided on the side of the frame base and which represent adhesive rolls and the frame base through suitable openings for the passage of the adhesive tape in the area of the tape deflection rollers in the receiving sliding position of the adhesive tape winding device is designed to form a scraper plate and in which the up / down control of the sliding position de r tape winding device in the holder depending on the movement of the lifting device, taking into account the gradual further transport of the adhesive tape, is made such that the tape winding device when
  • the invention is based on the object of specifying a further solution for an adhesive tape pickup arrangement for a device of the type described in the introduction, which, with relatively little technical effort, has a high degree of flexibility in adapting to flat workpieces of virtually any shape with high operational reliability.
  • the invention is based on the essential finding that a high degree of flexibility in adapting the pick-up arrangement to the shape of the workpieces to be picked up can be brought about in an extremely advantageous manner in that the pick-up arrangement is subdivided into a plurality of tubular pick-ups each representing an independent functional unit, which because of their independent functional properties a printing plate representing a common base plate can be fixed in practically any arrangement and can hardly be hindered by the finger shape with regard to their mutual arrangement, that is to say they can always be optimally aligned in their overall arrangement on the printing plate to the shape of a flat workpiece to be picked up.
  • a first depositing point preferably in the form of a magazine stacking the workpieces to be processed, is provided on both sides of the feed line representing the second depositing point.
  • the running platform bridging the three storage locations has, on a slide that can be moved along the running platform, two lifting devices which are arranged one behind the other in the running direction and at a distance from the second storage location from a first storage location and are synchronously controlled in their movement sequence. In this way, it is achieved that a workpiece can be placed on the second depositing point with each movement of the slide, while at the same time a picking-up process can also take place at each of the first two depositing points.
  • first storage locations are stack of workpieces that hold magazines accessible from above, the lateral boundaries of which are realized by brush elements with bristles oriented sideways and slightly downwards, and these brush elements adapt to the outer contour of a stack of workpieces on a base plate made of ferrous metal, for example a steel plate, can be fixed at a freely selectable location by means of holding magnets attached to the brush elements.
  • the adhesive tape transducers in one of the outer shaping of the workpieces to be accommodated according to arrangement and number on the printing plate are outstandingly suitable for a clean separation of the workpieces stored in a stack when brush magazines are given in the specified one Dimensioning is used.
  • One of the reasons for this is that not only the number and arrangement of the adhesive tape receivers, but also the brush elements that together form a brush magazine, are optimally adaptable according to the number and position of the outer contour and the area size of the workpieces combined in a stack.
  • the guided holder of the adhesive tape winding device is connected to the piston rod of a small compressed air cylinder accommodated on the side of the pressure plate in the tubular housing, which is connected via electrically controllable air valves and air hoses to a compressed air distributor arranged on the pressure plate.
  • the compressed air cylinder is controlled in the desired correspondence with the movement of the lifting device.
  • the use of a compressed air cylinder as a displacement drive for the adhesive tape winding device has the advantage of particularly simple assembly in the production of such sensors.
  • Such a compressed air cylinder enables a pressure of the adhesive tape on the flat workpiece to be lifted which can be set within wide limits, so that the required adhesion can be set as required for the most diverse materials of such workpieces.
  • Such a compressed air cylinder also allows the stroke to be set within relatively wide limits.
