Definitions

  • the invention relates to a device for stacking flat objects, preferably provided with positioning holes, preferably bags which are looped away from a plastic tube or semi-tube web and which are preferably transferred from a so-called Vicketer with transport arms rotating in pairs, arranged in pairs, consisting of a stacking section Endless, intermittently driven traction means running over deflection wheels or rollers, which are provided with upstanding stacking pins or needles attached to support plates.
  • the object of the invention is to provide a device of the type specified at the outset which, with simple adaptation to different formats and changing conditions, allows different types of processing on the stacks in a simple manner.
  • this object is achieved in that two stacking sections are provided and in that different tools for processing the intermittently conveyed stacking are optionally interchangeable and arranged in a frame-fixed manner between the stacking sections.
  • the arrangement of two stacking sections makes it possible to selectively arrange processing tools fixed to the frame between them, which can interact in any way, since it is no longer necessary to include the stacking plates which are moved intermittently as a counter-tool.
  • the two stacking sections can be designed correspondingly lighter because they only serve for stacking and no longer have to take on the function of counter tools.
  • the tools can consist of an abutment fixed to the frame in the region of the conveying plane, the length of which corresponds to the length of the stack in the conveying direction, and a heated, raised and lowered cutting knife of corresponding length, which is mounted in frame parts fixed to the frame.
  • a heated, raised and lowered cutting knife of corresponding length which is mounted in frame parts fixed to the frame.
  • double bags stacked on the stacking sections can be separated in the middle, the heated cutting knife simultaneously blocking the separated stacks on the cut surfaces.
  • the cutting knife and the abutment can be exchanged or completely removed as required.
  • the tools consist of an abutment plate fixed to the frame and of punching or holding punches and / or perforating knives which can be lowered thereon.
  • an abutment plate preferably provided with holding stamps, offers the advantage that it can be provided with cutouts, so that processing tools can also be arranged below the abutment plate, which pass through the cutouts for processing the stack. For example, a heated cutting knife can thus pass through the abutment plate from below for severing the stacks.
  • each stacking section which preferably consist of toothed belts, can also be provided with only one needle or a pin, so that after the stacks are separated by a longitudinal cut, the stack halves, which hang laterally over the stacking sections, rotate when the needle or the pin is arranged laterally, ie eccentrically. This rotation can be advantageous in order to move the cut surfaces away from the heated cutting knife.
  • the longitudinal beams of the two stacking sections are in the end frame a transverse axis mounted non-rotatably about its horizontal axis and supported in its central or front area by a stamp or the like on a support connecting the end frame to the wicket frame, which is rigidly connected to the end frame and is guided with its front end on a transverse axis of the wicket frame , the end frame being guided displaceably or displaceably on floor-fixed guides in the transverse direction and a device for moving the end frame in the transverse direction is provided.
  • both stacking sections are moved against each other.
  • both stacking sections are moved laterally together, to the extent that the stacking sections enclose the winding arms on one side between them.
  • the tool set does not need to be removed to operate the device with only one side stack, since it does not impair the stacking.
  • the longitudinal members of the stacking sections are mounted on the transverse axis of the end frame via slide bushes connected in a rotationally fixed manner, and both longitudinal members are provided with threaded nuts with opposing threads into which a common transverse spindle axis is screwed for adjusting the distance between the stacking sections , and that the longitudinal beams of the stacking sections are supported on a slide plate carried by the stamp or the like.
  • This configuration makes it possible to change the spacing of the stacking sections in a simple manner only by actuating the spindle in order to adapt to different formats.
  • a shaft 4 is provided which is provided with a drive (not shown) and which carries the transport arms 5 arranged in pairs and provided with suction devices or gripping devices.
  • a cross-welding separating device Arranged in front of the winder frame 3 is a cross-welding separating device, not shown, for welding bags off a plastic tube or semi-tube web, from which the rotating transport arms 5 take over the finished bags or double bags and needle them onto the stacking pins b, 7 of the stacking sections 8, 9.
  • the endless toothed belts carrying the stacking pins are moved intermittently by such a distance that a set of new stacking pins or needles is brought into the position in which the bags are removed from the transport arms.
  • the side parts 11, 12 of the end frame 10 are connected to one another by a front cross member 13.
  • a longitudinal member 14 is rigidly connected, which is provided at its front end with a bush 15, which on the a pipe or round steel existing transverse axis 16 of the wicket frame is guided to be displaceable.
  • the transverse axis 16 is connected to the side parts 1, 2 of the winder frame 3 by holding pieces 17, 18.
  • the end frame 10 has two rollers 19 in the region of its side parts 11, 12, which are guided in transverse floor-fixed guides.
  • the side parts 11, 12 of the end frame 10 are also stiffened in their rear region by a cross member 20, which carries on its underside a transverse rack 21 with which the pinion 22 of the gear motor 23 fixed to the ground meshes.
  • the end frame By actuating the geared motor 23, the end frame can be moved in the transverse direction on the rollers 19, the longitudinal member 14 being carried along and sliding over its front bush 15 on the transverse axis 16 of the winder frame 3 in accordance with the transverse displacement.
  • the longitudinal beams 24 of the two stacking sections 8, 9 are fixedly connected in the region of the end frame 10 to transverse bushings 25, preferably ball bushings, which are displaceably guided on a transverse axis consisting of a tube 26 or the like, which is held in the side parts 11, 12 are.
  • transverse bushings 25 preferably ball bushings, which are displaceably guided on a transverse axis consisting of a tube 26 or the like, which is held in the side parts 11, 12 are.
  • the side members 24 of the two stacking sections 8, 9 are supported on a slide plate 28 which is carried by a stamp 29 which is fastened on the side member 14.
  • the longitudinal beams 24 of the stack sections 8, 9 are provided at their front ends in a fork shape with bearing pieces 3U, between which the deflection wheels 31 are freely rotatable.
  • the rear ends of the carrier 24 are also fork-shaped with bearing pieces 32, between which the drive wheels 33 are mounted.
  • the longitudinal beams 24 of the two stacking sections are also provided with transverse threaded nuts 34 into which the opposite thread provided spindle 35 is screwed, which is rotatably mounted in the side parts 11, 12 of the end frame.
  • the spindle 35 passes through the side part 12 and is provided with a handwheel 36, by means of which the distance between the stack sections 8, 9 can be adjusted.
  • the freely projecting supports 24 of the two stacking sections slide on the plate 28 provided with a sliding coating.
  • the lower longitudinal member 14, which connects the winder frame 1 to the end frame 10, is provided with lateral base frame parts 41, 42 which are connected to the latter via flanges 40 and which carry side parts 43, 44. These side parts arranged to the side of the stack sections 8, 9 serve to hold tools that process the stack.
  • an abutment 45 is screwed onto the lower longitudinal member 14 and is provided with the bottom flanges 46, 47 receiving the screws.
  • the top of the abutment 45 is provided with a sufficiently heat-resistant plastic strip 48 for padding.
  • the top of this strip 48 lies in the region of the conveying plane of the stacking pins 50 carried by plates 49.
  • the plates 49 carrying the stacking pins 50 are alternately connected to toothed belts 51, 52 which run in parallel and in pairs.
  • the heated cutting knife 53 can be raised and lowered and cuts the stacks between the stacking pins 50.
  • an abutment plate 55 fixed to the frame is provided, which is provided with a central recess 50.
  • abutment plate 55 On the side parts 43, 44 lowerable holding punch 57 and perforating knife 58 are arranged.
  • a heatable cutting knife 59 Arranged below the abutment plate is a heatable cutting knife 59 which can be raised and lowered and which extends through the recess 55. After the holding punches 57 have been lowered, a stack lying on the abutment plate 50 can thus be severed by lifting the lower knife 59.
  • needles bl are fastened on the plates fastened to the toothed belt, onto which the bags can be needled by the support arms 5 without prior positioning holes.
