Definitions

  • the mechanical parts of the stacking device must work at very high speeds. To the speeds reasonably within tolerable limits hold, two stacks are formed one above the other by temporary supports are separated. Thereby is gained time to get a finished stack out of the To be able to remove the stacking device.
  • the temporary support means to bring it into the stacking shaft quickly enough without the risk of colliding with those at high speed incoming products.
  • the probability of a collision to reduce is in the known machine Rake that forms the temporary support means.
  • the rake can move its teeth through the slots of the protrude downstream stop to in the To form a stacking shaft of temporary support means.
  • the rake must perform a vertical movement in the shaft and it becomes at the bottom of the stacking shaft pulled out, outside the stacking shaft into the upper one Position returned to above the margin of the Products to be fed into the stacking shaft. thereupon it is in the stacking shaft in direct current with the in Chute dropping products moving down. Also there is no danger when the lowering speed is low the collision with incoming products because of the rake happens very quickly in the area where the products are over the take-off rollers are shot.
  • the known machine has a type of cross slide with two linear axes running at right angles to each other.
  • This arrangement is driven by two endless ones Belts that are connected to the support beam on which the Prongs of the rake are attached.
  • the drive takes place via a toothed belt that runs around fixed rollers.
  • the belt space curve must be designed so that the stroke of the rake in the direction of transport is sufficient, thus the teeth of the rake even for the largest products can be withdrawn behind the relevant stop. This is the way for very small products an extremely long idle stroke that takes up unnecessary time and also at very high speeds for small products forces. In particular, therefore, the folding machine can with small products not at higher speed work, although smaller products allow this easily would.
  • the temporary supports in the form of arithmetic are also used in the known machine to to hold down the stack of folding box tubes and depressed it in an output conveyor convict.
  • the rake In this area, the rake must run parallel to the exit route be led and is therefore over a longer period Time period not available for recording trimmings. To bridge this time, in which the rake for Stacking is not available, on the other hand the lifting table but can also not be used, there will be more Support means used in the form of fingers that way long carry the stack of incoming products until the Lift table has become free from the previous stack and in the stack height can be raised.
  • the first edition means are fingers or similar elements that are in the Clearance profile of the stacking shaft in front of or out of this can be moved back without making a vertical movement perform.
  • the second temporary supports act as hold-downs, around the finished stack formed on the lift table hold together and into the exit conveyor threading. To accomplish this task, the Carry out two movements with the second temporary support means. You have to move vertically through the stacking chute and they have to leave the clearance profile on top of that of the stacking shaft.
  • the tines move the second temporary support means not parallel to the axis of the stacking shaft, but along an arc with a large radius.
  • a swivel axis is provided for this purpose, which are perpendicular to the direction of transport and horizontal runs so that the bow movement occurs, which makes another linear axis superfluous. It is sufficient, in the solution according to the invention, if the second temporary support means only during the retraction movement from the stacking shaft and the feed movement in the stacking shaft move along a linear axis. The movement from top to bottom through the stacking shaft and outside the stacking shaft from bottom to top is not straight Move.
  • the upstream stop is designed as a vibrator. This also enables one Subsequent adjustment of the folding box hoses when the Seam is glued and the adhesive has not yet cooled completely is.
  • the finished stacks can be reliably removed can be achieved if the output transport device several parallel conveyor belts includes. Moving the stack away from the lifting table is improved, if it is also fan-shaped, and at least one of the conveyor belts into a gap between the prongs of the lifting table.
  • Additional conveyor belts can be found next to the lifting table run and up to its upstream Edge.
  • the upper folding box hoses are also re-pressed achieved by placing the finished stack in a hold-down device is pinched.
  • This is also expedient equipped with endless conveyor belts on the Work on top of the stack. The working dream of this Conveyor belts run parallel to the area that contains the working strand of the conveyor belts are formed on which the stacks rest.
  • FIG. 1 shows a device 1 for forming stacks 2 from flat products 3 for example folding carton blanks or folding box hoses.

  • You need small ones Folding box hoses 3 do not have the same stroke go through as with large blanks. In this way the folding machine that cuts the folding box 3 generated, run much faster with small blanks than with large blanks, so even though the cycle time is determined by the structure of the folding straps higher throughput occurs.
  • the upper yoke 9 or the lower frame 11 are lowered somewhat, whereby a greater depth of the stacking shaft is reached becomes. Accordingly, there is another one on the pillars 5 Set of fingers 25 'provided below the Fingers 25 lie, namely by the amount of the additional Stacking shaft depth.
  • a device for stacking folding box hoses has a height-adjustable lift table.
  • the first temporary support means are located above the lifting table, which are pulled out of the stacking shaft or into these can be advanced.
  • Another set of temporary support means can be both from the stacking shaft be pulled out as down in the stacking shaft be moved.
  • the second support means serve simultaneously to do this, press a finished stack together around it between a transport device of a hold-down device to be able to thread. While the lift table is together with the second support device with the removal of the Stapels is busy, the first temporary support means for the fact that in the Stacking shaft can be stacked.
