Definitions

  • the invention relates to a system for processing workpieces made of wood, plastic, aluminum and the like according to the preamble of claim 1 and a method for transferring workpieces between a first and a second clamping device according to the preamble of claim 10.
  • Known systems have a loading area and a processing area for the workpieces to be processed, which are advantageous stabför-shaped parts and are transported benefits with clamping table feeds through the system.
  • the charging and loading areas are at the same point within the system, so that loading and unloading cannot be carried out at the same time.
  • CONFIRMATION COPY and have a high positioning accuracy, which makes the system complex and expensive.
  • the invention is based on the object of designing the generic system and the generic method in such a way that the workpieces to be processed can be processed with a high degree of accuracy with a simple structure of the system.
  • the system according to the invention has the first clamping device, which has the at least one counter-stop for the workpiece that can be adjusted in the y-direction.
  • the workpiece In the loading area, the workpiece can be pushed and clamped against the counter stop in the y-direction without high positional accuracy.
  • the workpiece can be twisted to a certain extent or clamped at an angle on the clamping device.
  • the second clamping device which is located in the machining area of the system, has the at least one stop for the workpiece that can be positioned in the y-direction. As soon as the workpiece has been moved from the loading area into the machining area by means of the first clamping device, the workpiece can be pushed against the stop of the second clamping device positioned in the y-direction after releasing the clamping device of the first clamping table device.
  • the two clamping devices have very precise support levels on which the workpieces rest.
  • the substructure and the guide for the clamping devices have a very high level of precision and rigidity, because the workpieces in the machining area of the system must be machined with high precision.
  • the workpiece can be aligned in the y-direction after the clamping device of the first clamping device has been released. Since the supports or lower clamping jaws of the two clamping devices are very precisely aligned with one another, in particular have exactly the same height position, and both clamping devices of the clamping devices are released or opened, the workpiece can rest on the supports without tension Workpiece has been clamped at an angle or twisted in the clamping device of the first clamping device during the loading process, the workpiece, since it is exposed, is now moved against the impact of the second clamping device in the y-direction and is precisely positioned by means of the clamping device. The precisely aligned workpiece is then clamped in place with the clamping device of the first clamping device.
  • the workpiece is aligned in such a way that its long sides protrude so far beyond the clamping jaws of the clamping devices in the y-direction that the long sides can be provided with the desired profile.
  • the workpieces are advantageously aligned in such a way that they do not have to change their position when changing from the first to the second clamping device - or vice versa.
  • the second clamping device can also be moved back in the y direction for the second machining in order to generate a free space for machining tools. This process is time-neutral, because the second clamping device must be moved back in the y-direction for the transfer of the finished workpieces.
  • the second clamping device can be moved away from the first clamping device in an advantageous embodiment by means of the drive in the y-direction, so that the workpiece clamped in the first clamping device can now be machined with one or more tools.
  • This y-axis of the second clamping device is also used when the workpiece is to be transferred from the first clamping device to the second clamping device for further processing and is to be clamped by it. Then the second clamping device is moved so far towards the first clamping device in the y-direction that the workpiece can be transferred.
  • the y-axis which is required anyway, saves one axis in the loading area. This is all the more advantageous as the Liche stop extend over a large length and a corresponding effort must be made to ensure accuracy over the entire length of the stop.
  • the first clamping device can advantageously be moved along a guide that extends in the x direction.
  • the first clamping device can therefore be moved reliably from the loading area into the processing area of the system.
  • a simple structure of the system contributes in an advantageous manner if the second clamping device is arranged in the x-direction unadjustable in the processing area.
  • the second tensioning device is advantageously adjustable in the y direction along a guide. If the second tensioning device is to be adjusted in the direction of the first tensioning device or away from it, the guide ensures that the second tensioning device can be moved reliably.
  • the lower clamping jaw of the second clamping device is advantageously adjustable in the z-direction. This means that the lower clamping jaw can, for example, when transferring the workpiece from the first to the second Clamping device can be lowered slightly so that the workpiece cannot get stuck during transfer.
  • a structurally simple design of the system results in an advantageous manner if the clamping jaws of the second clamping device extend over the length of the second clamping device in the x-direction.
  • the entire second clamping device extends almost over the length of the machining area in the x direction.
  • the system is advantageously provided with at least one receiving unit for depositing the workpieces after processing, which can be moved in the x direction from the processing area into the loading area. If the receiving unit is in the processing area, the workpieces can be placed on the receiving unit after they have been finished. With it, the workpieces are moved in the x-direction to the loading area and there removed from the system by means of a suitable transport device. During this delivery process, the clamping devices can transport the workpieces in the system regardless of the position of the receiving unit.
  • the workpiece to be machined is initially picked up and clamped in the loading area by the first clamping device without precise positioning with respect to this clamping device. It is not important here whether the workpiece is twisted or clamped at an angle in the clamping device of the clamping device.
  • the first clamping device With the first clamping device, the workpiece is moved next to the second clamping device, the clamping device of which is open, so that the workpiece clamped in the first clamping device can be inserted between the clamping jaws of the clamping device of the second clamping device without problems.
  • the lower clamping jaws or supports of the two clamping devices are exactly aligned with one another in the vertical direction (z-direction), ie they are exactly aligned with one another.
  • the corresponding positioning axes must be used for a high quality Machining anyway have a high positioning accuracy.
  • the lower clamping jaws are exactly aligned with one another at the same height. This is necessary if the workpieces have a flat support side.
  • the supplied workpieces can, for example, already be provided with a fold, ie the workpieces are provided with an open-edged depression or groove, the so-called fold. This fold is limited in the vertical direction (z-direction) by a surface parallel to the support surface of the workpiece, with which the workpiece rests against the corresponding clamping jaw.
  • the clamping jaws of the two clamping devices are aligned with a height offset, but nevertheless exactly to one another, which corresponds to the dimension of the recess in the z-direction.
  • the clamping of the workpiece in the first clamping device is released.
  • the workpiece can then be aligned or positioned transversely to the x-direction in the y-direction by means of horizontally opposite stops. As a result, the workpiece is positioned exactly, even if it was previously clamped at an angle or rotated in the first clamping device.
  • the workpiece is then clamped in one of the two clamping devices and then processed.
  • the workpiece is positioned in such a way that in the clamped position it protrudes in the y direction over the clamping device.
  • the protruding workpiece area can then be machined with the appropriate tools.
  • the exact positioning of the workpiece is advantageously achieved in that, before being clamped in one of the two clamping devices, it rests against a counter-stop of the first clamping device and a stop of the second clamping device.
  • the second clamping device is retracted so far in the y-direction after the workpiece has been clamped that one side of the workpiece can be processed.
  • This side can overlap the corresponding long side Workpiece area as well as the top and / or bottom of the workpiece.
  • the exposed longitudinal side of the workpiece can be machined, in particular profiled, while bores, grooves and the like can be made in the upper / lower side of the workpiece.
  • the partially processed workpiece is advantageously transferred to the second clamping device within the processing area. With the clamping device open, it is shifted in the y-direction in the direction of the first clamping device.
  • the workpiece is always clamped so that the workpiece does not change its position during the transfer process. This contributes to a very high processing quality.
  • the clamping device of the first clamping device is advantageously only opened when the clamping device of the second clamping device has clamped the workpiece.
  • the workpiece is clamped in such a way that the still unprocessed area of the workpiece protrudes in the y-direction over the clamping device of the second clamping device, so that the required processing is carried out on the exposed longitudinal side and / or the top and / or bottom of the workpiece can be made.
  • the second clamping device can be moved back in the y-direction for this further processing so that the corresponding tools can reach the unprocessed workpiece area.
  • the first clamping device can be moved back to the loading area in order to pick up the next workpiece to be processed there. As soon as the workpiece has been finished in the second clamping device, it is transferred to a receiving unit with which the finished workpiece can be transported from the machining area back into the loading area.
