Definitions

  • the present invention relates to a safety device in the delivery of a sheet-processing machine, in particular a printing press, which comprises a conveyor system connected to a drive, which stacks sheets in a stacking space accessible for carrying out operating actions via access areas.
  • the sheets processed in printing presses are transported from a conveyor system which is part of a delivery arm to a stacking space which extends below the conveyor system and are deposited in stacks.
  • the conveyor system is usually designed as a chain conveyor system.
  • a stack carrier is used to hold the stacks in the stacking space, which is gradually lowered during production, so that the height of fall of the sheets after release by the gripper systems is approximately the same for each sheet.
  • the operator must also carry out operations on the delivery arm that require reaching into the stacking space, which is also associated with a risk of injury.
  • EP 1 059 257 A2 it is known to arrange a detector in the delivery of a sheet processing machine at a predetermined distance below the sheet conveyor from the side of the stack.
  • the detector recognizes whether the stack is opposite it at its level and thus detects an increase in the vertical extent of the free space below the sheet conveyor beyond a predetermined value as a result of the lowering of the stack.
  • the signal given by the detector when the predetermined value of the extension is exceeded is processed by the drive control in the sense of stopping a drive which is operatively connected to the sheet conveyor or in the sense of retracting a room divider.
  • a device for handling a stack formed by means of a sheet on a printing press which has a stacking space with an opening through which the respective stack can pass while displacing it horizontally.
  • the A shield is assigned to the opening, which is formed by means of a radiation curtain, the radiation curtain generating a stop signal when it intervenes. This is used to stop one of the lifting drives used for vertical displacement of the stack or to shut down the printing press. The operator is thus protected against injury from the gripper systems.
  • the possibilities for performing operating actions on the stacking space, such as setting stacking wedges or stacking correction, are limited in that they are associated with an undesired shutdown of the printing press.
  • the invention has for its object to provide a safety device that reduces the risk of injury to the operators working on the boom of a sheet-processing machine while maintaining the accessibility of the stacking space for performing operations.
  • the security device comprises an input device and detectors assigned to the access areas, which respond to the intrusion of an operator and is operatively connected to the drive in such a way that when an intrusion is detected, the drive is stopped, with inputs being able to be made by the operator on the input device
  • Individual access areas can be determined for the execution of an upcoming operating action and the operative connection between the safety device and the drive is deactivated in a predetermined time interval after entry for entry into those access areas which are determined by the respective entry. This ensures that the stacking space is shielded from the intrusion of an operator, which is not related to an operator action, even in the areas in which it is freely accessible for operator actions.
  • an input possibility representing the operating action is provided on the input device for each typical operating action to be carried out while penetrating into the stacking space.
  • Each operator action is assigned a selection of access areas depending on the type of operator action and the design of the boom.
  • Individual switches can be provided as input options, which are preferably arranged on the side of the boom on which the intervention in the stacking space is to take place. After actuating such a switch, the safety device automatically deactivates the operative connection for penetration into the access area assigned to the operating action. This reduces the risk of incorrect entries. Knowledge of the arrangement of the detectors is not necessary.
  • the specified time interval can be the same for all operating actions and can be dimensioned according to the operating action that regularly takes the longest time.
  • the operating actions are each assigned a time interval.
  • the time interval is dimensioned in such a way that the operator has sufficient time after making the respective entry to reach and carry out the location at which the operating action is to be carried out.
  • the active connection remains deactivated only for a small time interval measured on the production time, which is preferably a maximum of 20 seconds.
  • the automatic reactivation of the active connection is an essential safety element that prevents improper restriction of the safety of the operator by accidental or deliberate permanent deactivation. If the time interval is not sufficient to perform an operating action, the operator must make an appropriate entry again.
  • At least one detector is assigned to each access area, light barriers preferably being provided as detectors.
  • the number and arrangement of the detectors which are assigned to an access area depends on its spatial extent. The arrangement is such that when an operator enters an access area, at least one of the detectors responds.
  • the selection of access areas intended for setting stacking wedges or for stack correction extends immediately below the conveyor system along the sides of the layers that are not facing the sheet-processing machine.
  • the selection of access areas for taking the sample sheet extends immediately below the conveyor system along one side of the delivery arm to which a sample sheet removal device is assigned.
  • a selection of access areas provided for the removal of a stack extends over the height of the stacking space along one of the sides of the boom and a selection provided for inserting stack carriers extends immediately above the installation level of the boom along one of the sides of the boom.
  • a selection of access areas can also be assigned to any other operating action on the boom.
  • a single access area can thus be determined for the execution of different operating actions and can therefore also be part of more than one selection.
  • this keeps the drive stopped until a switch enclosed by the safety device is actuated.
  • This embodiment of the invention prevents the boom from being put into operation again while an operator is in the stacking space.
  • the safety device comprises a signal generator which indicates that the operative connection has been deactivated for the operator by emitting acoustic or optical signals.
  • the signals can be used to represent the extent of the deactivation that has taken place and / or the total time interval available for performing an operating action or the remaining time interval.
  • the drive connected to the conveyor system is designed as a single drive or is part of a main drive driving the sheet-processing machine, from which it can be uncoupled.
  • FIG. 1 shows the schematic representation of a boom of a sheet-processing machine
  • FIG. 2 shows the boom with a selection of access areas for setting stacking wedges or for stack correction on one side of the boom
  • FIG. 3 shows the boom with a selection of access areas for removing a sheet stacker.

  • the chain conveyor system is formed from gripper-carrying gripper carriages, which are connected to revolving chains, which revolve over sprockets arranged in pairs.
  • the gripper carriages take over the processed sheets from the last printing unit or coating unit of the printing press and convey them to a stacking space which extends below the conveyor system on the side of the delivery 1 facing away from the printing press. There, the sheets are released by the grippers of the gripper carriages and deposited into sheet stacks 4.
  • a stack carrier 3 carried by stacking lifting chains 2 is provided for receiving the printed sheets.
  • the stack carrier 3 loaded with the sheet stack 4 is lowered from the stacking lifting chains 2 to the level of the boom 1 and is conveyed laterally out of the boom 1 and thus out of the stacking space by means of transport, not shown.
