Definitions

  • the invention relates to a device for stacking flat objects provided with two positioning holes, preferably bags made of plastic film, consisting of a stacking section of endless, intermittently driven traction means running over deflecting wheels or rollers, the stacking pins arranged in pairs and attached to support plates, the stacking pins of which Distance from one another is changeable, are provided.
  • Such stacking devices are usually used in conjunction with so-called Wicketer trays, which are arranged behind a plastic bag or the like from a plastic tube or semi-tubular film welding cross-welding device and take over the plastic bags provided with positioning holes or the like with their radial arms and after rotation through about 180 ° needle onto the stacking pins for the purpose of stacking them, the traction means being moved intermittently by such a distance after forming a stack of a predetermined number of pieces that a new pair of stacking pins comes into its stacking position. Since bags of different formats with different spacing of the positioning holes are often to be stacked, there is a need to change the spacing of the stacking pins of each pair of stacking pins to adapt to different formats.
  • the traction means consist of an endless chain, the links of which are connected to the support plates for the stacking pin pairs.
  • Each stacking pin is provided with a foot plate, which is provided for its guidance in the longitudinal direction on its underside with a flank projecting over the support plate and on its top with two pins which are guided in the longitudinal groove of a clamping rail which is supported on the foot plates and can be clamped to the support plate by screws.
  • positioning arms which are pivoted and adjustable to the desired distance are arranged to the side and above the stacking distance and position the tips of the stacking pins inserted in their free ends in their pivoted-out state that the clamping rails can be tightened after appropriate alignment of the stacking pins.
  • the object of the invention is therefore to provide a device of the type specified in the introduction, in which the stacking pin pairs can be set up more easily and quickly to changed formats.
  • the traction means consist of two parallel belts or belts, alternately a belt or belt is connected to a support plate, each carrying only one stacking pin, and that the belts or belts in their position relative to one another can be set and locked in advance or lag.
  • the device according to the invention in order to set a changed spacing of all pairs of stacking pins, it is only necessary to adjust the bands or belts relative to one another to the desired spacing of the pairs of stacking pins. With a single adjustment process, all pairs of stacking pins are set to the desired distance, so that quick and easy format variability is achieved.
  • the belts or straps running parallel and close to each other carry the aligned support plates, which cover both belts or belts, so that the belts or belts with the support plates alternately carried by them offer a uniform image.
  • the stacking pins can be fastened anywhere on the support plates and are preferably located on their outer sides.
  • the belts expediently consist of toothed belts which are held in a form-fitting manner by the toothed wheels which form the deflection wheels, so that no slip which changes the spacing of the stacking pins can occur.
  • the toothed belts rotate over pairs of gears located at the beginning and end of the stacking section, each of which is arranged on a common shaft or axis, that the gears of one pair are freely rotatable relative to one another and the gears of the other pair in theirs Phases are mutually adjustable and lockable. To adjust the distance between the stacking pins of each pair of stacking pins, it is only necessary to change the phase position of the adjustable gears accordingly.
  • the phase pair which can be adjusted in its phase position, expediently consists of a first gear wheel provided with a hub, on which the second gear wheel is mounted, this second gear wheel being provided on its side with at least one elongated hole which is concentric with the common axis of the gear wheels and through which one enters a Threaded hole in the side of the first gear grips the clamping screw.
  • the clamp is required to set the desired phase position of the two gears screw just loosened and tightened again after adjustment.
  • the first gear is provided in connection with the hub with an annular shoulder, which overlaps an outer annular, axially projecting edge of the second gear at a radial distance, that the shoulder with an external toothing and Edge are provided with an internal toothing and that with these teeth meshes a pinion arranged in the annular space formed by the shoulder and the overlapping edge, which is connected to a shaft mounted in the first gear, which passes through it in an axial bore and ends with a is located on the outside of the first gear coupling piece for a wrench or the like.
  • the phase position of the gearwheels and thus the desired spacing of the stacking pins of each pair of stacking pins can therefore be set continuously.
  • the shaft must be supported with sufficient friction in the first gear so that no undesired automatic adjustment can occur.
  • the shaft 3 of the winding device which is provided with a drive, is mounted, the arms 4 of which are fastened in pairs on the shaft 3 and provided with suction devices or other gripping devices, which in a cross-welding device, not shown, of a plastic tube or semi-tube sheet Take over the welded-on bag and, with its ends projecting from one arm 4 of the winder and provided with two positioning holes, needle onto the stacking pins 5, 6 until a stack with a predetermined number of plastic bags is reached. As soon as a stack is formed, the stacking belt is set in motion intermittently until the next pair of stacking pins 5 ', 6' is in the stacking position.
  • the stacking section 7 consists of a carrier 8 which is fastened between the front side parts 1 and the rear side parts 9 of the machine frame 2.
  • an axis 14 is held on the supports 8 between laterally attached bearing pieces 10, 11, on which two gear wheels 15, 16 are freely rotatably supported by means of roller bearings.
  • the shaft 17 is freely rotatably supported via roller bearings, onto which the gearwheel 18 provided with the hub 19 is keyed.
  • the second gear wheel 20 is mounted on the step formed by the hub 19. This is provided with two oblong holes 21 offset by 180 ° and concentric with the axis of the shaft 17, the shape of which can be seen in FIG. 5.
  • the first gear 18 is provided with a step formed by an annular collar 24. This step is overlapped at a radial distance from an edge 25 of the second gear 20 which projects in the axial direction.
  • the edge is provided with an internal toothing 27, wherein in the annular space formed between the step and the internal toothing 27 there is arranged a pinion 28 which meshes with it and which is arranged at the end of a shaft 29 which is jagged in an axial bore 30 of the first gear wheel 18 is.
  • the shaft 29 is provided on the outside of the gear 18 with a coupling piece 31 for a wrench or the like.
  • the screw bolts 22 are loosened and the desired adjustment is made by rotating the pinion 28 with a wrench or the like. As soon as this is reached, the clamping screws 22 are tightened again.
  • the carrier 8 is supported on the shaft 17 by means of end fork pieces 33, 34 which are mounted on the shaft 17 via roller bearings.
  • the shaft 17 is provided with an intermittent drive, not shown, which is advanced by one stack spacing after the formation of a stack.
  • the toothed belts 35, 36 run parallel to one another via the toothed wheels 15, 16 and 18, 20.
  • the carrier 8 is provided on its upper side with a polished plate 37 on which the teeth of the straps 35, 36 slide in the upper run.
  • Carrier plates 38 which are aligned with one another in the conveying direction are glued onto the belts 35, 36 in alternation.
  • the support plate 38 shown above in FIG. 2 is glued to the left toothed belt 35, while the next support plate is glued to the right toothed belt 36.
  • a support plate 38 glued to the right toothed belt 36 can be seen in FIG. 2 in the lower strand.
  • Cover plates 39 are screwed onto the support plates 38, with which the stacking pins 5, 6 are connected.
  • the support plates 38 which have only a small width in the conveying direction so as not to hinder the circulation via the gear wheels, have shoulders on their lateral edges, into which screws are screwed onto the lateral guide plates 40, 41 in the region of the lower run and these towards the inside outstanding support strips 42, 43 grip.
