Definitions

  • the invention relates to a device for stacking sheet-shaped objects provided with a frame, with a conveyor belt arranged at least substantially horizontally in the frame and with a stacking table arranged vertically adjustable in the frame, whereby means have been provided to transport a sheet-shaped object, suspended at the bottom side of the lower part of the conveyor belt by means of sucking action, and to release the sucking action when the sheet-shaped object has arrived at the stacking table.
  • the invention aims to obtain a device of the above kind, whereby the sucking action can be released at the desired moment in a simple way and at the same time the very light object can be delivered positively to the stacking table.
  • the conveyor belt is formed by several adjacent air permeable belts, the lower parts of which extend under a bottom wall, provided with openings to let air pass, of a case in which a vacuum is to be generated, whilst between the belts up-and-down movable push off elements are movable, which are coupled with closing elements in the case for closing the air passage openings in the bottom wall of the case.
  • the sucking action can be released at the desired moment by closing the air passage openings in the case, while at the same time, with the aid of the push off elements the sheet-shaped object will be released from the conveyor belt, so that there will be no risk of the sheet-shaped object remaining stuck to the conveyor belt, in spite of the sucking action having been released, and thus not being delivered to the stacking table correctly.
  • the device shown in fig. 1 comprises a frame 1 in which a pair of stacking tables 2 and 3 are accommodated movable up-and-down.
  • Each conveyor has been constructed from a number of endless belts 6, extending parallel to each other, and horizontally and perpendicularly to the plane of fig. 1 and further guided around rolls 7 rotatable around horizontal axes of rotation.
  • each stacking table is constructed from a number of laths 8 extending parallel to each other, all this in such a way, that in the lowest position of stacking table 2 and 3 resp., said laths 8 will be situated under the upper parts of belts 6 of conveyor 4 resp. 5 for delivering the objects lying on the stacking table to the relevant conveyor 4 or 5, so that next these objects can be transported perpendicularly to the plane of drawing 1.
  • a case 9 has been arranged in the frame, in which, with the aid of means not further shown, a vacuum can be generated.
  • a closing plate 15 made of elastic material such as rubber has been provided, which is joined to a support plate 16. Fixed to support plate 16 are upwardly extending rods 17, which are mutually coupled by a cross-rod 18. Cross-rod 18 is coupled to piston - rod 20 of an adjusting cilinder 21 with the aid of an arm 19, in such a way that closing plate 15, from the position shown in fig. 2, in which said closing plate closes openings 14 in the bottom of the vacuum case, can be moved upwardly for exposing said openings.
  • plate-shaped push off elements 22 are coupled with the support plate 16, said plate-shaped elements 22 extending vertically and being movable up-and-down between belts 11 forming conveyor 10 between the position, in which said plate-shaped elements, as shown in fig. 2, extend with their lower most ends at some distance below the belts 11 and a position, in which the lower most edges of the plate-shaped elements are situated above the bottom sides of the belts 11.
  • the device is provided with a supply conveyor 23 near an end of the frame.
  • sheet-shaped objects 24 While in operation sheet-shaped objects 24 will be supplied in the direction according to arrow B with the aid of the supply conveyor. The movement of said sheet-shaped objects as well as the number of sheet-shaped objects can be controlled with the aid of sensors not further shown.
  • a sheet-shaped object supplied with the aid of conveyor 23 will be sucked against the bottom side of conveyor 10, because vacuum has been generated in vacuum case 9 and openings 14 in the bottom of the vacuum case have all been exposed.
  • stacking table 2 When a sufficient number of sheet-shaped objects has been delivered to stacking table 2, the closing plate which is situated over stacking table 2 will no longer be moved downward but kept in its raised position, so that the sheet-shaped object can move further on into the direction of stacking table 3. As soon as a sheet-shaped object has arrived at stacking table 3, it will be delivered to stacking table 3 in-a similar way as described above. During said loading of stacking table 3 stacking table 2 can be moved further downward for delivering the sheet-shaped objects to conveyor 4 and, after discharging of the sheet-shaped objects with the aid of conveyor 4 the table 2 can be brought back to its starting position.
  • stacking table 3 After a sufficient number of sheet-shaped objects has been placed on stacking table 3 the delivering of sheet-shaped objects to stacking table 2 will be resumed again, while in the meantime stacking table 3 will move further downward to deliver the objects to conveyor 5. After said objects have been discharged, with the aid of conveyor 5, stacking table 3 can be brought back into its starting position, after which the cycle described above can repeat itself again.
