Definitions

  • the present invention concerns a method for stacking thin objects, in particular envelopes, whereby the objects are fed in an overlapping manner with a preceding object lying partially on top of a following object, and are pushed one under the other against a stop, such that the stack is formed from bottom to top.
  • Such methods are applied to form a small stack under the suction part of the supply of a printing press with a continuous load for printing envelopes.
  • the envelopes are fed at a more limited speed but partially overlapping one another, and they are stacked into a small stack at the input of the press, under the suction part. While the stack is being formed from beneath, the suction part always picks the top envelope from the stack to provide it in the press.
  • the invention aims a method for stacking thin objects which avoids the above-mentioned disadvantages and allows for a flawless stacking from bottom to top, in particular of envelopes being fed to a printing press.
  • This aim is reached according to the invention in that, at a distance from the stop which is smaller than the distance between successive overlapping objects, an air line is created from under the stack being formed, such that the bottommost object is blown upward to make a following object go underneath it up against the stop.
  • the air line is preferably blown through a table which is erected between the stop and for example an endless conveying device which feeds the objects.
  • the stack can be formed under the suction part of the supply of the printing press.
  • envelopes can be fed and stacked.
  • the air flow can be adjusted as a function of the weight of the objects.
  • the invention also aims a device which is particularly appropriate for applying the method according to any of the preceding embodiments, and which, in a simple manner, provides for a flawless stacking without any risk of wrong creases or breakdowns during the further processing, in particular the printing in a printing press.
  • the invention also concerns a device for stacking thin objects, particularly envelopes, which are fed in an overlapping manner with a preceding object lying partially on top of a following object, against a stop, characterised in that it contains means to create a vertical air line near the stop.
  • These means for creating an air line preferably contain a blowing room which is provided with an air slot in its top wall and means for supplying air under pressure to the blowing room.
  • the top wall of the blowing room is preferably inclined upward towards the stop.
  • the distance between the stop and the air slot is for example about 1 cm.
  • the device can be part of the supply of a printing press, whereby the stop or a part thereof can be part of said printing press.
  • the blowing room can have an upward directed edge which is connected to a stop of the printing press.
  • the blowing room can then be erected between the printing press and an endless feeding conveyor device.
  • the device for stacking envelopes 1 from underneath represented in figures 1 and 2 is part of the supply of a continuously fed sheet-fed machine 2, of which is only represented a part by means of a chain line in figure 2, and is erected under the suction part 3 of this printing press 2.
  • This suction part 3 is provided with moveable suction cups in a known manner.
  • the device itself mainly consists of a stop 4 and a blowing room 5 erected against it whose top wall 6 is provided with an air slot 7 for creating a vertical air line.
  • the two standing end walls 8 of the blowing room 5 are fixed to the two standing walls 9 of a conveying system. Of the latter is only represented a cylinder 10 which is erected between the standing walls 9 such that it can rotate and over which are moved a number of belts 11 upon which the envelopes 1 are supplied.
  • This cylinder 10 is situated at a distance from the blowing room 5.
  • the top wall 6 of this blowing room 5 is inclined in a descending manner towards the cylinder 10, and the protruding edge of this top wall 6 is situated lower than the top side of the belts 11.
  • the air slot 7, however, is situated higher, at a distance from the stop 4 which is smaller than the distance between the successive overlapping envelopes 1 and which is for example about 1 cm.
  • a plate On the side of the printing press 2, a plate is fixed to the blowing room 5 which protrudes over the top wall 6 and which forms a protruding edge 12 which is part of the stop 4.
  • This edge 12 is connected to a stop lath 13 which is fixed to a support 14 of the printing press 2 and which forms the stop 4 above the edge 12.
  • the working of the stacking device is as follows.
  • the overlapping envelopes 1 to be stacked are fed, such that a following envelope 1 is situated with its front part under the rear part of the preceding envelope 1.
  • the envelopes 1 overlap one another with a part which is significantly larger than the distance between the air slot 7 and the stop 4, and they are normally situated with their flaps on the front side and with their sides to be printed on the top side.
  • Air is continuously blown through the blowing device 17 via the air line 16 into the blowing room 5, where this air flows upward as an air line via the air slot 7.
  • the top envelope 1 is each time picked up by the suction cups of the suction part 3 and provided in the sheet-fed machine 2, so that the height of the stack remains practically constant.
  • the above-described stacking device can be combined in an interesting manner with a device for the overlapping feeding of thin objects from a stack to a conveying device, whereby use is made of a vacuum.
  • Figure 3 schematically represents such a combination.
  • the latter device for the overlapping feeding of envelopes 1 contains a rotor 18 which is provided with openings 19 and which can rotate around a stator 20 which is provided with a room 21 which opens into its outer perimeter via a slot 22 opposite the stack of envelopes 1 which is erected on top of the rotor 18.
  • the room 21 is connected to the suction side of the blowing device 17 via a line 23, which thus also forms a vacuum pump.
  • the rotor 18 is driven via belts by means of a cylinder 24 situated next to it, driven by a motor which is not represented, which is also part of an endless conveyor device 25 with belts 26, which are connected to a reversing device 27 with belts 28 which take over the envelopes 1 upside down and which are connected to the conveyor device with the cylinder 10 and the belts 11.
  • one envelope 1 is placed on top of another one, after the reversal by the reversing device 27, the envelope 1 will be situated under the other one.
  • the envelopes 1 are thus fed to the blowing room 5 and are stacked in the above-described manner.
  • the feeding of the blow air to the blowing room 5 and the extraction of the suction air from the room 21 can be carried out by two different compressors.
