Definitions

  • This invention refers to an automatic stacking device for automatically forming piles of sheets by overlaying layers pre-formed by one or more groups of sheets, which groups are placed side by side, said stacking device being apt to be inserted downstream of a preparatory unit of layers of groups of sheets.
  • the apparatus generally described at points 1) and 2 show the different method of support and ejection of the material to be stacked since on avails itself of a plane which slides away transversally, whereas the other uses two planes, one opposed to the other, which transversally slide out.
  • the above mentioned apparatus differentiate one from the other also in the way through which they perform levelling, since the first was developped for the purpose of stacking a plurality of types of materials and therefore avails itself of a semiautomatic levelling where also the manual intervention of the operator is necessary in order to improve such operation; the second apparatus was devised specifically for corrugated cardboard and avails itself of an automatic levelling, only however on the single group of sheets and when suspended above said planes.
  • the device according to this invention improves and adds the following characteristics:
  • the stacking device is mainly formed by four groups, and precisely:
  • the stacking device comprises a horizontal table or plane 1 provided with motor driven rollers to receive the layer of groups of sheets and convey it against a vertical rigid fixed wall 2, in order to improve the front levelling; said motor driven roller plane is movable transversally to the direction (arrow F in figure 2) of travel of the layer and is provided with a device (not shown), which, by means of an electric limit switch (not shown) allows its exact positioning with respect to a movable wall 4.
  • the wall 4 besides assuming two distinct positions by means of the mechanism controlled by pneumatic cylinder 7 (figure 4), is capable of moving to any whatsoever area which the program of the operating cycle instructs it to, ' since it is mounted on a frame 5 slidable on guides 11 along which it is moved through an arrangement 12 with rack and pinion geared motor and is positioned at a pre-set measure by means of an electronic coder device (not shown).
  • a fixed wall 10 is mounted, in coincidence of which there is another arm 9, which is like the arm 6 and is movable (by not shown driving means) horizontally and parallelly with respect to wall 10 (on guide 9') and pivoted so as to rotate by 90° on a horizontal plane through the action of a pneumatic cylinder 9"; through such rotation it can move away from the fixed wall 10.
  • a motor driven roller plane 8 is mounted below the table 1; said plane 8 can move vertically like a lifting device, in order to receive the layers, descend from time to time only according to the thickness of the individual layer, for the number of programmed layers, and once said number is reached it continues its descent till it reaches an electric limit switch (not shown) where it stops and causes the motor of its rollers to start for effecting the ejection of the pile.
  • a motor driven roller plane 16 apt to receive the pile, which plane, depending on the requirements, may be mounted in a fixed way, i.e. resting on the floor (figure 3, B), or may be a lifting plane in order to bring the pile at optimal heights again (figure 3, A).
  • the cycle begins at the arrival from upstream apparatus, at intervals of time greater than the total time of the cycle of the stacking device, of a complete layer, formed by one or more groups of sheets.
  • a complete layer formed by one or more groups of sheets.
  • Such a layer upon entering the stacking device, darkens a photodiode (not shown) placed at the input, which controls the starting of the motor driven rollers of the table 1.
  • the layer enters completely the stacking device and, being pushed by the motor driven rollers of the table 1, collides and therefore levels against wall 2, where a photodiode (not shown) controls the stopping of the rollers; then the movable wall 4.is moved (by cylinder 7) towards the layer and a photocell (not shown), placed on the wall 4, when it sees the initial part of the layer, controls the sliding out of table 1; in this way the layer rests on the wall 3, and wall 4 ends its travel, stopping at the pre-set measure, which is equivalent to the length of the layer.
  • wall 3 (by cylinder 13) moves back into the position where it is aligned with wall 10, while the movable arms 6 and 9 are shifted at the rear wall of the layer, reading the exactness of the stopping position through a direct reflexion photocell (not shown) and stop, and then through rotation by 90° (by means of 6" and 9", respectively) they level the layer pushing it towards the fixed wall 2; at the same time the wall 4, by means of its pneumatic cylinder 7, pushes the layer towards walls 3 and 10.
  • the wall 4 and the arms 6 and 9 move away from the layer and the lifting plane 8 descends vertically only by the thickness of the individual layer; in fact, said photocell placed to sight in underneath the table 1, as soon as returned in light, controls the stopping of the lifting plane 8 and the simultaneous return motion of table 1, which goes to stop into the position of beginning of the cycle, ready to receive a new layer.
  • the above mentioned cycle repeats for the programmed number of times, which correspond to the number of layers which are to be overlaid on the lifting plane 8, in order to reach the height of pile which it is intended to obtain; once the last layer has been unloaded, the lifting device 8 continues its descent till it stops at an electric limit switch (not shown) placed so as to cause a mating of the level of the roller plane 8 with the level of the roller plane 16.
