Definitions

  • the invention relates to a method for transferring sheets from a feeder of a sheet-processing machine to a transport system of the sheet-processing machine according to claim 1.
  • a respective gripper carriage has a gripper bridge, to which grippers are fixed, which grasp the arches at a front end.
  • a gripper carriage further has lateral carriages, which are connected to endless chains of the transport system and whereby the gripper carriage to be moved by the machine.
  • Such a flat bed punch is for example from the DE 30 44 083 A1 known.
  • the two tables are equipped with cutting and scoring tools or corresponding counter tools with which out of the cyclically guided between the table surface arches punched out the benefits and at the same time pressed the necessary for clean folding grooves. In the subsequent breakout the waste is removed by machine tools. Depending on the equipment of the machine finally the punched benefits can be separated in a designatedWhentrenn arthritis.
  • a sheet is transported from the feeder into the grippers of the sheet transport system.
  • the transport is done for example by a belt table.
  • the gripper Upon arrival of the bow, the gripper is in a stop position.
  • the alignment of the sheet is done by mechanical front marks, also referred to as front marks, and side pull marks.
  • a disadvantage of this principle is that only a small limited time window is available for the alignment of the sheet.
  • the grippers of the transport system are attached to gripper carriages, which are moved synchronously and in the machine cycle by the sheet-processing machine. In all processing stations as well as in the docking station results in a rest time of uniform duration. This represents the available alignment time, in which the sheet must first rest against all leading brands and only then can be aligned laterally. Due to the small time window available, the sheet must not show large position deviations when entering the grippers, ie. H. high demands are placed on the accuracy of belt table and feeder.
  • a disadvantage of this second principle is the need for the additional module, as this additionally causes costs, requires space and requires a clock processing with the sheet processing machine.
  • the additional acceleration and the additional braking of the sheet are disadvantageous, as this can lead to deformations of the sheet at high production rates and thus high transport speeds.
  • the object of the present invention is therefore to describe a method for transferring sheets which overcomes or at least mitigates the disadvantages of the previously described principles.
  • the method according to the invention advantageously makes possible a precise and exact alignment of a respective sheet. Due to the orientation of the sheet outside the transport system is advantageously sufficient for accurate alignment time window available. It is also advantageous that can be dispensed with additional facilities such as beam system or pre-gripper or swing gripper.
  • the gripper carriage 8 of the sheet transport system 7 are moved on a movement path 70.
  • the gripper carriage 8 are driven by linear motors 71, wherein in Fig. 1b only a linear motor 71 is indicated by way of example.
  • According to the gripper carriage 8 are moved to take over sheet 6 from the feeder 1 on its trajectory 70 to shortly after the transfer point Ü and stopped there.
  • a gripper carriage 8.1 in this reversing position is in Fig. 1b indicated by dash-dotted lines.
  • the reversal position is only a few millimeters behind the transfer point Ü and is in Fig. 1b only shown for greater visibility with a greater distance from the transfer point Ü.
  • the gripper carriage 8 is now a short distance against the Sheet transport direction B moves backwards in accordance with arrow R.
  • the gripper of the gripper carriage 8 are opened.
  • a rotational movement d is introduced about an axis of rotation 80 of the gripper carriage 8 and thereby lowered the gripper carriage.
  • the bearing surface of the gripper is thus below the bottom edge of the sheet, the gripper tip comes to rest above the top of the sheet.
  • the so moved backwards and lowered gripper carriage with open grippers is in Fig. 1b denoted by 8.2.
  • the front marks 17 can now be lowered by a movement a and the sheet 6 can be released for the transfer.
  • Forward movement in the sheet transport direction B, backward movement R and stopping of the gripper carriage 8 are effected by appropriate control of the linear motors 71.
  • the control of the linear motors 71 takes place here by the machine control 15 of the sheet punching and embossing machine 100.
  • a respective gripper carriage 8 is assigned a desired position on its trajectory at one time.
  • the movement profile includes forward movement in the sheet transport direction B, stopping and backward movement R.
