Abstract

The invention relates to a workpiece stop, a signal output device for outputting a signal directly perceivable to an operator of a workpiece processing machine from his/her working position, an imaging device for generating at least one image of the interior of a workpiece processing machine, a device for monitoring a processing position of a workpiece, a work-piece processing machine, a use of a device for monitoring a processing position of a work-piece, a use of a workpiece processing machine and a method for processing a workpiece in a workpiece processing machine. These devices and method promote safe and efficient operation of a workpiece processing machine.

First claim

The invention claimed is:

1. A workpiece stop for a workpiece processing machine, comprising,
at least one finger stop having at least one contact surface for a workpiece; and
at least one sensor,
wherein the at least one finger stop can be at least partially aligned for monitoring a contact of the workpiece with the workpiece stop and a correct processing position of the workpiece in the workpiece processing machine, the at least one finger stop having an alignability when docking the workpiece, and
wherein the at least one finger stop is associated with in each case at least one of the sensors and the sensor is designed such that it contacts the workpiece with the finger stop and determines an orientation of the finger stop corresponding to the correct processing position of the workpiece.

2. The workpiece stop according to claim 1 , wherein the at least one finger stop is at least partially movably and/or rotatably seated in an end position corresponding to the correct processing position of the workpiece.

3. The workpiece stop according to claim 1 , wherein the sensor includes a switch and is designed so as to determine the contact of the finger stop with the switch in the correct processing position of the finger stop.

4. The workpiece stop according to claim 2 , including at least one element selected from
at least one blocking element, wherein the at least one finger stop is associated with in each case at least one of the blocking elements and the blocking element is designed and/or positionable such that it blocks a movement and/or rotation of the finger stop in the end position; and
at least one preload element, wherein the at least one finger stop is associated with in each case at least one of the preload elements and the preload element is designed and/or positioned such that it provides a restoring force acting on the finger stop in the end position thereof.

5. The workpiece stop according to claim 1 , wherein the at least one finger stop has a lower part and an upper part and a central part arranged therebetween, and the upper part and/or the lower part are seated movably and/or rotatably relative to the central part.

6. The workpiece stop according to claim 5 ,
wherein the central part is immovable.

7. A device for monitoring a processing position of a workpiece in a workpiece processing machine, selected from a bending press and press brake, including:
a workpiece stop according to claim 1 .

8. The device of claim 7 , further including;
an imaging device for generating at least one image of an interior of a workpiece processing machine, in particular a workpiece processing machine with an interior which is not or is only incompletely visible for an operator from his/her working position, the imaging device including:
an image capturing unit adapted to receive at least one image of the interior of the machine or a part of the interior; and
an image display unit configured to display the at least one image;
wherein at least one of the image capturing unit and the image display unit is configured to present the image corresponding to a virtual operator perspective of the interior of the machine from his/her working position,
wherein the image capturing unit includes at least one mirror, in particular an adjustable mirror, for mirroring the interior of the machine and at least one camera for capturing at least one image of the mirrored interior.

9. The device according to claim 8 , the imaging device for generating at least one image of the interior of a workpiece processing machine further including:
a unit for detecting the working position of the operator; and/or
a projection unit configured to project a mark of a correct processing position of a workpiece to be processed into the interior of the workpiece processing machine.

10. The device according to claim 8 , wherein
the mirror is adjustably formed at a height and/or inclination, the inclination being relative to a vertical, for detecting the at least one image of the mirrored interior corresponding to the virtual perspective of the operator in the interior of the machine from his/her working position, wherein the image display unit includes or is or can be connected to a computing unit for converting the at least one image of the mirrored interior according to the virtual perspective of the operator to the interior of the workpiece processing machine from his/her working position.

11. The device according to claim 7 , further including a signal output device for outputting a signal directly perceptible to an operator of a workpiece processing machine from his/her working position, having a vibration generating unit for generating and transmitting a vibration to an operating element of the workpiece processing machine as the signal.

12. The device of claim 11 , wherein in the signal output device the vibration generating unit is designed such that it can be coupled in a vibration-transmitting manner to the operating element; and/or
wherein the vibration generating unit includes a mechanical and/or acoustic vibration generator; and/or
wherein the operating element includes one or more elements selected from a foot pedal, a floor mat, a handle, a remote control, a glove, a shoe, a watch, a mobile phone, a pair of headphones, a pair of glasses, a control panel, and any combination thereof; and/or
wherein the signal output device is designed for wired or wireless reception of a vibration-triggering control command.

13. A workpiece processing machine, in particular a workpiece processing machine with an interior which is not or is only incompletely visible to an operator from his/her working position, in particular a bending press and/or press brake, including:
a workpiece stop according to claim 1 .

14. The workpiece processing machine of claim 13 , further including:
an imaging device for generating at least one image of the interior of a workpiece processing machine, in particular a workpiece processing machine with an interior which is not or is only incompletely visible for an operator from his/her working position, the imaging device including,
an image capturing unit adapted to receive at least one image of the Interior of the machine or a part of the interior; and
an image display unit configured to display the at least one image;
wherein at least one of the image capturing unit and the image display unit is configured to present the image corresponding to a virtual operator perspective of the interior of the machine from his/her working position,
wherein the image capturing unit includes at least one mirror, in particular an adjustable mirror, for mirroring the interior of the machine and at least one camera for capturing at least one image of the mirrored interior.

15. The workpiece processing machine according to claim 14 , the imaging device for generating at least one image of the interior of a workpiece processing machine further including:
a unit for detecting the working position of the operator; and/or
a projection unit configured to project a mark of a correct processing position of a workpiece to be processed into the of the workpiece processing machine.

16. The workpiece processing machine according to claim 14 , wherein the mirror is adjustably formed at a height and/or inclination, the inclination being relative to a vertical, for detecting the at least one image of the mirrored interior corresponding to the virtual perspective of the operator in the interior of the machine from his/her working position, wherein the image display unit includes or is or can be connected to a c
