Definitions

  • the invention relates to a device for stacking any flat object and more particularly a stacking device which stores in horizontal stacks flat objects conveyed in a unitary and vertical fashion by a belt conveyor for example.
  • Document FR-A-2 489 798 discloses a device for stacking thin and flexible objects driven by a conveyor, of the type stated in the preamble of claim 1.
  • This device comprises a fixed body and a rotating drum pierced with openings mounted around the fixed body.
  • the fixed body has a plurality of chambers open towards the drum, which are distributed so as to be between the reception zone on the drum of the objects driven by the conveyor and the substantially opposite zone on the stacking drum and holding the pile. These chambers are successively put under vacuum or pressure through individual valves on the connecting pipes to the suitable source.
  • the arrival of objects near the drum is detected and puts successive chambers under vacuum as the objects advance, for their guidance to the top of the stack in formation.
  • the chambers are successively pressurized to detach their rear part from the drum.
  • the receptable is a tray receiving the battery, the position of which is controlled as the battery is built up.
  • plies to be stacked on a stacking carriage are directed between the stack being formed and a stacking drum, through a slot, and the driving of the stacking carriage is controlled by a probe which reacts to the pressure of the stack.
  • the stack is formed on a bottom plate and is held by an adjustable rear edge.
  • the folds are detached from the drum by sets of belts with separating elements which drive the front part of the folds to the lateral edge by applying it against the pile, their rear part is pressed against the pile by air jets.
  • FIG. 1 shows, top view, a horizontal section of the stacking device of the invention.
  • flat objects 1 are approached on edge by a belt conveyor 2.
  • a drum 3 rotating on itself in the direction of the arrow F1 is mounted coaxially on a cylindrical body 4 fixed and having a hollow recess 5.
  • the axis of rotation of this drum is orthogonal to the direction of arrival of the objects 1 according to arrow F2 and is substantially parallel to the surface of these flat objects.
  • the drum 3 has a plurality of openings 6 regularly distributed around its periphery. These openings 6 establish a communication for the passage of air between the outer 7 and inner 8 faces of the drum 3.
  • a pedal 20, articulated on an axis 21 parallel to the axis of the drum, comprises a pad 22 flush with the package 23 of flat objects 1 stacked in the receptacle 10.
  • a handle 24 of the pedal 20, located on the same side of the pad 22 relative to the axis 21, comes to request a detector 25.
  • This pedal 20 is held in the equilibrium position by a return spring 26.
  • the detector 25 can be of an electromechanical type.
  • the electrical signals produced by the detectors 25, 27 and 28 are directed on a control circuit 29, for example of an electronic type.
  • the control circuit 29 controls the commissioning of motors from a set of motors 30. These motors, not shown, in particular control the rotation of the plug 18 as well as the advancement of the means of transport of the receptacle 10.
  • the conveyor 2 is arranged on the side of the drum 3. Its outlet is oriented in an oblique direction relative to the surface of the objects already stacked in the receptacle. He directs the object 1 to be stacked to insert it between the package of objects 23 and the drum 3. On leaving the conveyor 2 the object 1 obscures the photoelectric cell of the detector 27 and this detector 27 sends a pulse to the circuit pilot 29. After a time delay corresponding to the time necessary for the go before the object 1 comes to be inserted between the package 23 and the drum 3, the pilot circuit 29 sends an order to the tilting motors of the plug 18 This plug 18 then turns in the direction of arrow F5, from a closed position to the open position shown in FIG. 1. Under these conditions, the suction source connected to the recess 5 sucks the rear face of the front front of the flat object to be stacked. This face is said to be posterior with respect to the direction of advance it will have in the receptacle 10.
  • the orifice 9 has a development on the periphery of the body 4 limited on the order of two to three times the width of the step distribution of the openings 6 on the drum 3. As soon as the openings 6 of the drum 3 having participated in the aspiration of the object to be stacked have exceeded the limit of the orifice 9 they are no longer in connection with the source of aspiration. The front edge of the object 1 which was then pressed into a rolling contact on these active openings of the drum comes off naturally.
  • the drum continues its action until the front edge of the object to be stacked abuts on the jogging edge 11.
  • the duration of this elementary action is limited by a time delay taking into account the speed of rotation of the drum 3 and of the distance separating the jogging edge 11 and the diameter of this drum parallel to this jogging edge.
  • This time delay is a function of the time taken by the front edge of the object to be stacked to cross the distance separating the orifice 9 from the jogging edge 11.
  • This circuit actuates the motor of cam 31 so that it performs a revolution on itself.
  • the speed and instant of passage of this cam 31 are calculated so that its end is erased in front of the front front of the stacking object which arrives, and so that in a continuous rotating movement it comes to press the rear front of the object just stacked on package 23.
