Abstract
A bending machine, in particular a swivel bending machine, is provided that defines a safety-relevant work area in which an operator of the bending machine is present during its operation, loading, unloading or the like, having a safety module comprising a safety barrier which provides a variable-size shield for the safety-relevant work area such that a shut-off state and an access state can be generated, wherein in the shut-off state access to the safety-relevant work area is at least partially restricted and wherein in the access state access to the safety-relevant work area is at least partially granted. A method is provided for processing a workpiece by means of a bending machine.
Claims21
1-28. (canceled)
A bending machine which defines a safety-relevant work area in which an operator of the bending machine is present during its operation, loading, unloading or the like, wherein the safety-relevant work area is the area in front of the bending machine which at least uninvolved and/or unauthorized and/or non-instructed persons must not enter during a bending process for safety reasons, having a safety module, the bending machine comprising:
- a safety barrier which is at least one selected from the group consisting of (i) planar and (ii) plate-shaped, which is retractable and extendable, and which provides a variable-size lateral shield for the safety-related work area such that a shut-off state and an access state can be generated, wherein in the shut-off state access to the safety-relevant work area is at least partially restricted and wherein in the access state access to the safety-relevant work area is at least partially granted.
A method for processing a workpiece by means of a bending machine, wherein the bending machine defines a safety-relevant work area in which an operator of the bending machine is present during its operation, loading, unloading or the like, wherein the safety-relevant work area is the area in front of the bending machine which at least uninvolved and/or unauthorized and/or non-instructed persons must not enter during a bending process for safety reasons, wherein the bending machine comprises a safety barrier which is configured in the form of a surface and/or plate, which is retractable and extendable, and which helps to provide a variable-size lateral shield for the safety-related work area, the method comprising:
- moving the safety barrier to create an access state in which access to the safety-relevant work area is at least partially granted;
- loading the bending machine with a workpiece;
- moving the safety barrier to create a shut-off state in which access to the safety-relevant work area is at least partially restricted;
- and
- processing the workpiece.
