  • the invention is based on the object of providing a device and a method which improve the process reliability when removing a workpiece part from a remaining workpiece.
  • a device of the type mentioned at the outset having a sensor device which is designed, based on the first and second contact elements, to completely separate the workpiece part from the remaining workpiece in a first test state and to fix the workpiece in a second test state To check the workpiece part on the holding device in the fixed state.
  • the sensor device of the device enables, in a first test state, a test to determine whether the workpiece part has been completely separated from the remaining workpiece or whether it is still in contact with the remaining workpiece.
  • a test to determine whether the workpiece part has been completely separated from the remaining workpiece or whether it is still in contact with the remaining workpiece.
  • the contact elements can be used to check whether or not there is an electrical connection between the workpiece part and the remaining workpiece. The check as to whether the workpiece part has been completely separated from the remaining workpiece is typically carried out when the workpiece part has been moved in a removal movement in the removal direction out of the workpiece plane so far that it is above the surface of the remaining workpiece.
  • the second test state of the sensor device is typically used when the workpiece part has been moved out of the workpiece plane in a removal movement in the removal direction and the separation from the remaining workpiece has been tested.
  • it can be checked whether the at least one first and the at least one second contact element are electrically connected to one another via the workpiece part.
  • the sensor device is designed, in the first test state, an electrical resistance between the at least one first and / or to determine the at least one second contact element on the one hand and a reference potential on the other hand.

If the workpiece part is still in contact with the remaining workpiece, a closed circuit is created when a voltage is applied between the contact elements on the one hand and the ground potential on the other, and a very low electrical resistance is measured between the contact elements and the ground potential.

If a plurality of first and second contact elements are present, an electrical resistance is determined between the plurality of electrically conductively interconnected first contact elements on the one hand and the plurality of electrically conductively interconnected second contact elements on the other hand.
  • At least one first contact element contacts the workpiece part at a first contact point and at least one second contact element contacts the workpiece part at a second contact point, so that the first and second contact elements are connected in an electrically conductive manner via the workpiece part.
  • a lower electrical resistance is measured between the first and second contact elements than in the event that the workpiece part is no longer fixed on the holding device. In the latter case there is no electrical contact between the first and second contact elements and the electrical resistance is practically infinite.
  • the first and second contact points or the corresponding first and second contact elements should not be arranged too far apart from one another on the holding device.
  • the holding device has a plurality of holding elements for fixing the workpiece part, the holding elements being switchable between a fixing state for fixing the workpiece part and a release state for releasing the workpiece part.
  • the holding elements are spaced apart from one another on the holding device, typically in a regular arrangement, for example in a grid arrangement.
  • the holding elements are designed as suction grippers.
  • the fixing state is achieved by applying a vacuum or by a negative pressure by which the workpiece part is held on the suction gripper.
  • the detection of whether the workpiece part is fixed to the suction gripper is not possible via the vacuum or via a negative pressure generator, since with such suction grippers the flow valves also close if the workpiece part is not fixed to the suction gripper .
  • the at least one first contact element and / or the at least one second contact element are formed on the holding elements.
  • individual or all of the holding elements for example in the form of suction grippers, are made of an electrically conductive material, at least on one side that is brought into contact with the workpiece part or the remaining workpiece.
  • folded suction cups of the suction grippers which are used to contact the workpiece part or the remaining workpiece, can be formed from an electrically conductive plastic.
  • the first and second contact points coincide with the fixing points of the holding elements. In this case, however, there is the problem that the two tests described above are not possible on workpieces or sheets with foil or rust, since the foil or rust layer applied to the surface is generally not electrically conductive.
  • first contact element (s) and / or the second contact element (s) are / are arranged between the holding elements.
  • the first or the second contact elements can also be arranged in a regular arrangement or in a grid on the holding device. Since holding elements in the form of suction grippers have an essentially circular geometry, at least on the inlet side on which the fixation or suction takes place, there is usually enough space between the suction grippers to arrange contact elements between the suction grippers.
  • first contact elements alternate with second ones in at least one direction perpendicular to the removal direction Contact elements.
  • the holding device or the holding elements are typically integrated in a substantially plate-shaped housing which extends in a plane perpendicular to the removal direction.
  • the first and second contact elements alternate in at least one direction in this plane. If the holding elements are arranged in a grid, a respective holding element can be arranged in one or in both directions of the grid between a first contact element and a second contact element.
  • the contact elements do not necessarily have to alternate in more than one direction in order to carry out the tests described above. However, the distance between the first and second contact elements or between the first and second contact points should not be too large so that the tests described above can also be carried out on small workpiece parts.
  • the first contact elements and / or the second contact elements have resilient contact pins for contacting the workpiece part or the remaining workpiece.
  • the holding device has a rigid abutment, for example in the form of a flat contact surface, in which bores are made for receiving the holding elements, for example in the form of suction grippers, as cited in the introduction DE 10 2014 209 811 A1 is described
  • the contact pins of the first and the second contact elements typically protrude with their free end over the flat contact surface and are pressed in when the workpiece part or the remaining workpiece presses against the flat contact surface, the electrical contact being established.
  • the use of resilient contact pins if dimensioned appropriately, makes it possible, in the case of foiled or rust-bearing sheets, to slightly scratch the sheet or rust layer and in this way to establish electrical contact with the sheet below.
  • first contact elements and the second contact elements are each connected to one another in an electrically conductive manner via conductor tracks on the same circuit board. It goes without saying that the conductor tracks which connect the first contact elements to one another in an electrically conductive manner and the conductor tracks which connect the second contact elements to one another in an electrically conductive manner are not in an electrically conductive connection to one another.
  • the contact elements are in this case attached to the circuit board and can be arranged at a comparatively small distance from one another.
  • first contact element (s) are attached or fastened to a first electrically conductive component and the second contact element (s) to a second electrically conductive component offset in the removal direction to the first .
  • the first and the second electrically conductive component are electrically isolated from one another.
  • the two components can be designed, for example, as electrically conductive perforated plates into which the contact element or elements are screwed.
  • second contact elements, which are fastened to the second perforated plate can be guided through the first perforated plate via an electrically insulating spacer (electrically insulated).
  • the device comprises at least one lifting device which can be moved in the removal direction to remove the workpiece part from the remaining workpiece, the workpiece part being held between the at least one lifting device and the holding device during at least part of the removal.
  • the lifting device engages the workpiece part on the side opposite the holding device and serves to support or support the workpiece part.
  • the holding device serves as a counter-holder and enables the workpiece part to be stored during movement in the removal direction between the lifting device and the holding device perpendicular to the workpiece plane, so that it does not get caught on the remaining workpiece during removal.
  • the lifting devices can be designed, for example, in the form of lifting pins which can be actuated in a controlled manner independently of one another. The lifting devices are actuated in such a way that the workpiece part is aligned parallel to the workpiece plane when it is moved in the removal direction.
  • Another aspect of the invention relates to a processing machine for the separating processing of plate-like electrically conductive workpieces, in particular sheet metal, by means of a processing tool, for example a laser cutting device or a punching tool, further comprising: a Device as described above for removing a workpiece part that has been separated from the remaining workpiece during separating machining.
  • a workpiece support which serves to support the workpiece during the separating machining, can also form a workpiece support of the device for removing workpiece parts from the remaining workpiece.
  • a workpiece transfer device can be arranged in the processing machine, by means of which the remaining workpiece can be moved together with the separated workpiece part from a processing position of the processing machine for the cutting processing of the workpiece to an unloading position of the device for removing the workpiece part.
  • Another aspect of the invention relates to a method for removing a workpiece part from a remaining workpiece, in particular by means of a device as described above, comprising: contacting the workpiece part at at least one first contact point by means of at least one first contact element, and contacting the workpiece part at at least one second contact point by means of at least one second contact element, wherein the first and second contact elements are formed on a holding device and connected to a sensor device, moving the workpiece part in a removal direction, transferring the holding device to a fixing state for fixing the workpiece part on the holding device, and checking the complete Separation of the workpiece part from the remaining workpiece in a first test state of the sensor device and testing of the fixation of the workpiece part on the holding device in a second test state of the sensor device.
  • the workpiece part is first moved in the removal direction and then the holding device is transferred into the fixing state, or vice versa.
  • the workpiece part can be moved in the removal direction by means of the holding device, by means of a lifting device or by means of a combination of holding and lifting device. It is also irrelevant in which order the complete separation of the workpiece part from the remaining workpiece and the fixation of the workpiece part on the holding device are checked. Both tests can also be carried out alternately several times in a row.
  • an electrical voltage is typically applied between the at least one first and / or the at least one second contact element on the one hand and a reference potential on the other hand, and an electrical resistance between the at least one first and / or the at least one second contact element Contact element and the reference potential determined.
  • an electrical resistance between the first contact element and the second contact element is measured.
  • a plurality of first or second contact elements that are conductively connected to one another can alternatively be used.
  • a resistance measurement between the first and / or second contact elements on the one hand and a reference potential, typically ground potential, on the other hand can be used to determine whether the workpiece part has been completely separated from the remaining workpiece or not.
  • the workpiece part can be fixed to the holding device before or after the workpiece part is moved in the removal direction. If the workpiece part is moved in the removal direction, for example with the aid of one or more lifting devices, the workpiece part is not fixed to the holding device until after the removal movement. If, on the other hand, the holding device is also used to move the workpiece in the removal direction, the workpiece is fixed before the removal movement and the fixed workpiece is lifted by the holding device. To check the fixation, a voltage is applied between the first and the second contact element or between a first and second plurality of contact elements in the second test state.
  • a lower resistance is measured during the resistance measurement in the second test state than in the event that the first and second contact elements are not electrically connected to one another via the workpiece part Are connected so that the resistance measurement can be used to check whether the workpiece part is attached to the Holding device is fixed.

  • a first switch S1 is connected in parallel to the second resistance measuring device W2, and a second switch S2 is in series connected to the first resistance measuring device W1 and to the first and second contact elements 41, 43, respectively.
  • the first contact element 41 and the second contact elements 43 have resilient contact pins 41a, 43a, the free ends of which bear against a first contact point K1 and second contact points K2 on the workpiece part 14, respectively.
  • the sensor device 45 enables a check to be made as to whether the workpiece part 14 has been completely separated from the remaining workpiece 15 or whether there is still an electrically conductive connection between the workpiece part 14 and the remaining workpiece 15.
  • the sensor device 45 is in an in Fig. 3a first test state P1 shown, in which the first switch S1 is closed, so that the first contact element 41 and the second contact elements 43 are connected to one another in an electrically conductive manner.
  • the second switch S2 is also closed, so that the electrical resistance R1 between the first and second contact elements 41, 43 on the one hand and the reference potential M on the other hand can be measured via the first resistance measuring device W1.
  • the reference potential M corresponds to im
  • the example shown shows the potential of the remaining workpiece 15, which is connected to the ground potential of the processing machine 1 via the clamping claws 13 or via the workpiece support 17.
  • the lifting process can be repeated or an error signal can be output.
  • the removal of the workpiece part 14 can be continued.

  • the sensor device 45 is operated in a second test state P2, in which the first switch S1 and the second switch S2 are open, as shown in FIG Figure 3b is shown.
  • the second resistance measuring device W2 determines the resistance R2 between the first contact element 41 and the second contact elements 43, which at the corresponding first contact point K1 and the second contact points K2 with the workpiece part 14 are in contact, provided that this is fixed on the holding device 24.
  • the electrical resistance R2 is that of the second Resistance measuring device W2 is measured, very small. If, on the other hand, the workpiece part 14 is not fixed to the holding device 24, the first contact element 41 is electrically isolated from the second contact elements 43, so that the electrical resistance R2, which is measured by the second resistance measuring device W2, is very high or practically approaches infinity . If it is recognized during the check that the workpiece part 14 is not fixed on the holding device 24, an attempt can be made again, for example, to fix the workpiece part 14 on the holding device 24. Alternatively, an error signal can be output.

  • the removal device 16 is used to automate such a flying optics machine, this is also possible without an additional lifting device.
  • the holding device 24 is in this case first placed on the surface of the workpiece part 14 and then the vacuum generator of the holding device 24 is switched on. The holding device 24 is thereby transferred from the released state to the fixing state in which the workpiece part 14 is fixed or fixed on the holding device 24.
  • the holding elements 39 can be used, for example, as Active suction devices can be designed, the opening state of which can be changed by means of a controller.
  • the holding device 24 can be adapted to the shape of the workpiece parts 14 to be removed such that holding elements 39 are arranged only in the region of the workpiece part 14.
  • a contact plate 37 is not necessary in this example.
  • FIG. 11 shows a plan view of the underside of an alternative holding device 24 with suction grippers 39.
  • the first contact elements 41 and the second contact elements 43 are fastened on a common printed circuit board 54.
  • the first contact elements 41 are connected to one another in an electrically conductive manner via first conductor tracks 51, while the second contact elements 43 are electrically conductively connected to one another via second conductor tracks 53, which are electrically isolated from the first conductor tracks 51, as shown in FIG Fig. 4 is shown by way of example only for two rows of contact elements 41, 43.
  • the first contact elements 41 alternate with the second contact elements 43 only in the X direction, but not in the Y direction.
  • the fastening of the first and second contact elements 41, 43 on a common printed circuit board 54 makes it possible to position the first and second contact elements 41, 43 at a smaller distance from one another than in the case of the one in FIG Fig. 3a, b shown example.
  • the suction grippers 39 themselves can be designed as (first or second) contact elements.
  • the nipple sleeves 40 are typically made from an electrically conductive material, for example from an electrically conductive plastic.
  • the suction grippers 39 can be divided into two groups, which are each connected to one another in an electrically conductive manner in order to form the first and second contact elements 41, 43. It goes without saying that only the first contact elements 41 can be formed on the suction grippers 39, while the second contact elements 43 are arranged between the suction grippers 39, or vice versa.
