Definitions

  • the invention relates to a method for removing at least one cut workpiece part from a plate-shaped workpiece and to a device for carrying out the method.
  • a device for separating two workpiece parts from each other comprises a workpiece storage. Above the workpiece storage a removal console with gripping elements is provided. Below the workpiece support a push-out console with push-out pins is provided. To separate the cut workpiece part from the plate-shaped workpiece, the gripping element is placed above the cut workpiece part and the Ejection pins are positioned underneath the cut workpiece part. Both are then fed onto the workpiece part. The ejection pins then lift the workpiece part upwards relative to the support plane and the workpiece part is gripped and transported away by the gripping elements, in particular vacuum suction cups.
  • the lifting of the workpiece parts upwards from the plate-shaped workpiece takes place adjacent to a processing machine which separates at least one workpiece part from the plate-shaped workpiece by cutting.
  • a processing machine for separating workpiece parts from a plate-shaped workpiece is known from DE 10 2018 215 738 A1.
  • a cutting head is moved above a plate-shaped workpiece in order to direct a cutting beam onto the plate-shaped workpiece and to separate the workpiece part from the plate-shaped workpiece.
  • an ejection unit with a punch fixed to the cutting head is positioned towards the cut workpiece part so that this workpiece part is pressed downwards within the processing space of the cutting head for the separating processing by the punch.
  • the invention is based on the object of proposing a method and a device for removing at least one cut workpiece part from a plate-shaped workpiece, thereby enabling process-reliable automation and a high cycle time.
  • a method for removing at least one cut workpiece part from a plate-shaped workpiece in which the plate-shaped workpiece with the at least one cut workpiece part is placed on a workpiece support, preferably in a device for removing workpieces, wherein an ejection device on an ejection console above the workpiece and a counterholder with a pressing plate on a removal console below the workpiece is positioned and brought into contact with the workpiece part to be pressed out and cut, and then a joint lowering movement of the pressing device and the counterholder relative to the workpiece support plane is controlled until the workpiece part is positioned below the plane of the workpiece support and then the pressure plate of the counterholder is moved from a horizontal orientation for pressing out the workpiece part into an inclined position for removing the pressed workpiece part.
  • the ejection device and the counterholder are moved into an ejection position which lies within a workpiece support surface or is adjacent to it and that the plate-shaped workpiece with the workpiece part to be ejected is moved into the ejection position by the clamping device between the ejection device and the counterholder and the ejection position can be outside, preferably laterally outside, the workpiece support. This allows both large and small workpiece parts extending across the surface to be ejected safely. By transferring the workpiece part for ejection into the ejection position outside the workpiece support surface or adjacent to it, a free design of the workpiece support can be made possible.
  • a conveyor belt which preferably extends along the workpiece support, or at least a receiving container is positioned below the ejection position and preferably adjacent to the workpiece support and the workpiece parts are transported away or collected. This enables an optimized process chain to be made possible depending on the subsequent further processing.
  • the pressure plate of the counterholder which can be tilted or folded down from a horizontal position, allows the pressed-out workpiece part to be easily transferred to the conveyor belt or the receiving container by gravity.
  • a workpiece support which is formed from several parallel support webs, each with a free space or gap between them, the plate-shaped workpiece with the at least one cut workpiece part, one extension direction of which is smaller than the free space or the distance between two support webs, is positioned on the workpiece support in such a way that the at least one workpiece part rests at least partially on the one support web and that, in order to press out the cut workpiece part, a displacement movement of the plate-shaped workpiece is controlled by moving the workpiece support and/or the clamping device, so that the cut workpiece part to be pressed out is positioned above the free space between the support webs.
  • the pressing device is moved along the pressing console and the counterholder is moved along the removal console into the pressing position to the workpiece part, the workpiece part is pushed through the free space between the Support webs of the workpiece support are pressed downwards and the pressure plate of the counterholder is tilted and the workpiece part is transferred to a conveyor belt of the removal console, which preferably transfers the pressed workpiece part into the receiving container or the conveyor belt.
  • This can also increase the process reliability for removing workpiece parts from the plate-shaped workpiece.
  • the workpiece parts are completely cut free from the plate-shaped workpiece. Due to the positioning of the workpiece part during pressing between the pressing device and the pressure plate on the counterholder, preferably in a clamped manner, a process-reliable removal is possible.
  • the at least one cut workpiece part is connected to the plate-shaped workpiece by at least one connecting web.
  • This connecting web can be formed, for example, by a welded connection, by an adhesive connection or by a so-called micro or nanojoint.
  • a joint is understood to mean that the plate-shaped material is connected in one piece to the workpiece via the remaining web.
  • the thickness of the web can correspond to the thickness of the plate-shaped material.
  • the thickness of the connecting web is advantageously less than the thickness of the plate-shaped material. This can be controlled, for example, by the burning or cutting process.
  • the object underlying the invention is further achieved by a mechanical manufacturing process in which the at least one workpiece is at least partially or completely separated from the plate-shaped workpiece in a processing machine, but remains within the workpiece part, in which the plate-shaped workpiece with the at least one workpiece part is led out of the processing machine and fed to a pallet changer, wherein the plate-shaped workpiece with the at least one workpiece part is fed from a pallet changer into a device for carrying out the method according to one of the embodiments described above.
  • the pallet changer By transferring the plate-shaped workpiece with the at least one workpiece part into a separate device, in particular a removal device, which is separate from the pallet changer and the processing machine, the pallet changer can load and unload the processing machine with plate-shaped workpieces and the processing time in the processing machine is not interrupted by a removal process. This makes it possible to achieve a high cycle time when processing the plate-shaped material in the processing machine.
  • this removal process can be separated from the separation process in the processing machine and the loading and unloading process by means of the pallet changer.
  • the object underlying the invention is further achieved by a device for removing at least one cut workpiece part from a plate-shaped workpiece, in which an ejection device on an ejection console and a counterholder with a pressure plate on a removal console can be positioned adjacent to the workpiece part to be ejected and a joint lowering movement of the ejection device and the counterholder relative to the workpiece support plane can be controlled and the ejection plate of the counterholder can be transferred from a horizontal position to an inclined position after the workpiece part has been lowered below the workpiece support plane.
  • the counterholder can be moved along the removal console and the ejection device can be moved along the ejection console. This allows any position to be assumed relative to the workpiece support in order to cause the cut workpiece part to be ejected. Depending on the design of the workpiece support, this can take place inside the workpiece support as well as outside the workpiece support or adjacent to the workpiece support.
  • the counterholder can be moved up to a front end of the removal console and the ejection device can be moved up to a front end of the ejection device into an ejection position, and this ejection position is outside the workpiece support or adjacent to it and by assuming the inclined position of the pressure plate, the ejected workpiece part can be transferred from the counterholder into a conveyor device assigned to the front end of the removal console or at least into a receiving container. This can enable simple and secure disposal of parts.
  • the removal console along which the counterholder can be moved, has a conveyor belt, by which the workpiece part that has been pressed out and removed by the pressure plate can be picked up and transferred into the conveyor device or the at least one receiving container.
  • This arrangement makes it possible for workpiece parts that have at least a width that is smaller than a distance between support webs of a workpiece support to be pushed out downwards within the workpiece support and transported away.
  • the workpiece support is positioned in a receiving position within a base frame and can be moved into a pallet changer and back again and/or into a storage area arranged adjacent to the base frame and back again.
  • a stacking pallet can be arranged below the workpiece support. This makes it possible, for example, after the at least one workpiece part or all workpiece parts have been pressed out of the plate-shaped workpiece, which forms a so-called residual grid, to hold the plate-shaped workpiece part or the residual grid by a clamping device and move the workpiece support outside the base frame so that the residual grid can then be placed on the stacking pallet.
  • the object underlying the invention is further achieved by a mechanical arrangement which carries out a processing machine for separating at least one workpiece part from a plate-shaped workpiece at least partially or completely, wherein the at least one workpiece part remains in the plate-shaped workpiece and in which the plate-shaped workpiece with the at least one workpiece part can be led out of the processing machine and fed to a pallet changer, wherein the plate-shaped workpiece with the at least one workpiece part can be fed from the pallet changer to a device according to one of the above embodiments.
