Definitions

  • the invention relates to a method and a device for automatically feeding individual loose stacks of sheets from a printing machine into an adhesive binding machine, wherein the stacks of sheets from the printing press are staggered on a stack
  • the present invention is therefore based on the object to provide a method and an apparatus with which originating from a printing press stack of sheets, which are staggered on a pile stacked on each other, automatically a perfect binding machine can be fed individually for binding.
  • the top sheet stack is arranged at a defined height and close to a horizontal conveyor. This can be done in such a way that the stack is arranged on the front side or also laterally of the transport device, which is usually designed in the form of a conveyor belt. It is advantageous to arrange the stack with the sheet stacks thereon on the end face of the transport device so as to facilitate the feed in the transport direction. In order to arrange the upper stack of sheets defined, the entire stack with the loose sheet stacks thereon in height and, if necessary, can also be positioned laterally so that the simplest possible transfer of the upper stack of sheets to the transport device is possible.
  • the upper and lower stacks are gripped on the protrusion projecting from the stack by the offset by means of a first and second ply gripper to grip the following feature C in partially peeling off the upper sheet pile Sheet stack of the stack by means of the upper sheet stack holding sheet gripper to prevent slipping of the sheet stack located under the upper sheet stack.
  • a peel-off gripper which preferably securely grips the sheet stack in two places and pulls down the stack of sheets from the stack and according to feature E the stack of sheets on the horizontal transport means with a defined distance to the leaves the previous stack of sheets.
  • the peel-off gripper transports the stack of sheets at the same speed of the conveyor. This ensures that the loose stack of sheets does not slip when placed on the transport device.
  • the peel-off gripper is ready to take over another stack of sheets already partially pulled down from the stack and is moved back towards the stack. At the same time lying on the conveyor belt stack of sheets are fed to the perfect binding machine.
  • the next stack of sheets which is now the upper sheet stack, is again positioned at a defined height and near the transport device.
  • the process proceeds in the same way, with the difference that the offset of the now upper stack of sheets to the now next lower sheet stack is 180 degrees from the previous cycle. This applies both to the offset in a plane direction and in two plane directions (x, y).
  • the next stack of sheets underneath is gripped by means of the free layer gripper according to feature B so that both sets of sheets are held laterally before being pulled off. Subsequently, the features C to F are repeated.
  • the free bearing gripper now moves down when gripping back to grasp the now second upper layer.
  • the sheet gripper which still grips the upper sheet stack, is moved upwards with the stack for positioning the stack in a defined height. This improves the speed of destacking.
  • the intervention in the intermediate space can take place by means of a thin lift or similar suitable means in conjunction with a correspondingly formed gripping device.
  • the upper sheet stack can be gripped and at least partially withdrawn from the stack with the gripping device becoming active in this case.
  • the offset of the individual stacked loose stack of sheets usually takes place only in one direction, so that the supernatants of the stacks of sheets are always arranged at 180 degrees to each other.
  • the trigger may be made either transversely or longitudinally to the offset.
  • the stacks of sheets will have a simple offset, ie, in only one planar direction.
  • the stack with the individual sheet stacks has a defined contact edge in the direction of the horizontal transport device.
  • the stacks of sheets are drawn off from one another transversely to the offset of the stacks of sheets.
  • the defined contact edge and the trigger transverse to the offset also slightly in the direction opposite to the contact edge direction variable formats.
  • the method thus running thus enables the desired continuous operation at high cycle speed and without slippage of the individual sheets of a sheet stack.
  • the sheet stacks are placed on the transport direction of variable bands of the horizontal transport device, which serve as memory to achieve a same Anreihungsabstandes the sheet stack.
  • a delay occurs, which can occur, for example, when either a new stack of loose sheet stacks introduced and the stacking process is therefore interrupted, or if according to a further advantageous embodiment of the stack is filled from below.
  • This process can also lead to a brief interruption of the stacking process, because the top sheet stack must be accurately positioned again.
  • this interruption can be absorbed, so that the sheet stack is fed continuously to the perfect binder.
  • the upper sheet stack is positioned with the lower edge at the level of the transport device or with an offset to the height of the transport device of a maximum of +0.5 mm in order to minimize the height difference.
  • the stack is already positioned for the next top sheet stack as soon as the previous stack of sheets has been pulled from the stack.
  • the features A to C with the subsequent sheet stacks are advantageously executed simultaneously with feature F for the preceding sheet stack. The means that a gripping of the sheet stacks is already performed when the previous sheet stack is still fed to the transport device.
  • the thickness of the sheet stacks and / or the gap between the sheet stacks and the sheet stacking edges of the two upper sheet stacks are detected in the region of the offset in order to control the exact positions for the depression and / or engagement in the gap ,
  • the holding down and the gripping takes place pneumatically and the devices required for this purpose are actuated by means of servomotors in the horizontal and vertical directions.
  • the device according to the invention for automatically feeding individual loose stacks of sheets from a printing machine into an adhesive binding machine has a vertically movable stack carrier on the front side of a horizontal transport device for receiving a stack of individual loose stacks of sheets, Detecting means for detecting the edges of the two upper stack of sheets in the region of the offset, Detecting means for detecting the thickness or the gap between the stacks of sheets, Detecting means for positioning the upper sheet stack in a defined position to the front side of the transport device, right and left hold-down in the region of the edge opposite the projection of the respective sheet stack, horizontally and vertically movable right and left gripping means for gripping the two upper sheet stacks on the projection and moving the sheet stack in the direction of transport means, and a pull-off gripper movable in parallel with the transport device for gripping the stack of sheets separating from the stack by means of the gripping device and depositing the stack of sheets on the transport device on.
