Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • Such known devices consist of two movement groups.
  • the first is called the friction assembly and consists of the friction conveyor belts or wheels and fixed or slowly counter rotating wheels, which together form a product lock, i.e. a blank separate from the product stack and the second movement group, to promote the so-called conveyor assembly.
  • This conveyor assembly normally consists of a pair of shafts with conveyor rollers or conveyor belts. The conveyor speed this conveyor assembly is usually larger than that of the friction assembly.
  • the conveyor assembly ensures that the products within the friction assembly be separated from the product stack, faster than promoted in the pre-promotion and thus clean of the following product. Both the culvert the product lock and the distance between the pair of shafts in the conveyor assembly must be on the product, in particular its thickness.
  • the friction assembly and the conveyor assembly are made by driven a common drive.
  • To keep up To reach the shafts of the conveyor assembly are the shaft pairs usually connected with two spur gears. Out of it it follows that the distance between the shafts of the conveyor assembly can only be varied in a small range. This area is due to the flow of force between the spur gears limited. Stronger products can then be no longer support reliably.
  • the invention is based on the object of a device to create according to the preamble of claim 1 reliable products in a large thick range, i.e. in particular also reliably cut thicker blanks and promotes.
  • the common drive preferably an electric motor, drives the endless double-sided toothed belt in the invention on the corresponding drive pulleys the different shafts, depending on how the direction of rotation is desired.
  • the conveyor rollers or belts which receive the blanks emerging from the product lock, working co-operatively is a corresponding wrap required with the double-sided toothed belt.
  • the one Tooth washer is through the teeth on one side of the Timing belt and the other pulley through the teeth driven on the other side.
  • the distances of the straps or Wheels can be adjusted in a large area too to change thick products.
  • a clamping device (claim 2) ensures that the timing belt is always properly tensioned is over for an exact positive drive and circulation to care.
  • the device is advantageously designed in this way as indicated in claims 3 to 5.
  • the separating device shown in the drawing of paper, cardboard blanks or the like. different Thickness, designated 11, consists of two movement groups, namely a friction assembly and one Conveyor assembly.
  • the friction assembly is replaced by friction conveyor belts or wheels 2 and cooperating with them stationary or slowly counter-rotating wheels 4 are formed, which together form a product lock.
  • the downstream Conveyor assembly is supported by a pair of shafts Conveyor rollers or belts 3a, 3b are formed.
  • the waves of this Conveyor assemblies are driven at higher speeds so that those separated within the friction assembly Cuttings are conveyed faster than in pre-funding and thus be separated cleanly from the subsequent product.
  • the distance between the funding of the individual modules is adjustable. This is by double arrows 7 and 8 indicated. As a result, the adaptation to different takes place thick products.
  • the common drive 1 drives a double-sided toothed belt, i.e. a timing belt that has teeth on both sides has, so that it also on both sides for a corresponding can provide positive power transmission.
  • This timing belt wraps around the toothed disks as shown in FIG. 2 of the waves to be driven.
  • FIG. 2 the waves of the friction conveyor belts or -Wheels 2 and the conveyor rollers or -wheels 3a and 3b the downstream conveyor assembly.
  • a tensioning device 6 which is shown schematically in Fig. 2, ensures that the double-sided toothed belt 5 always the desired tension has, depending on how the adjustment is made at 8. It can be seen that to drive in the desired direction sometimes the one and the other toothed side of the timing belt 5 takes effect.
  • the slowly rotating counterclockwise wheels 4 are clocked via a freewheel, the arm 7 with a Eccentric 10 on the shaft of the conveyor rollers or wheels 3a is trained.
  • the shaft is supported in a second freewheel, which only rotates the shaft in the switching direction of the Allows lever arm.
  • When returning the lever is the Rotation of the shaft blocked by the second freewheel, so that a reciprocating movement of the arm 9 a one-way The shaft and thus the wheels 4 are forced to move.
