Definitions

  • the invention relates to a plate processing system according to the preamble of claim 1.
  • Such a plate processing system is from DE 10 2017 120 471 A1 known.
  • This contains a processing station for processing a plate-shaped workpiece and a support and transport device through which a plate-shaped workpiece can be moved in a path-controlled or regulated manner relative to the processing station in the direction of a first linear axis (X axis).
  • the support and transport device has two spaced-apart support and transport units for displacing the plate-shaped workpiece across a gap between the support and transport units.
  • the processing station contains two identically constructed processing units arranged in the gap, each of which has a cross member that can be moved in a second linear axis (Y-axis) and a third linear axis (Z-axis).
  • a processing unit that can be rotated about at least two axes of rotation is arranged at the freely projecting ends of the two separately movable cross beams. Especially when machining particularly wide workpieces, it can happen that the cross members arranged on two vertical supports cantilever out relatively far, which can affect the stability and manufacturing accuracy.
  • the object of the invention is to create a plate processing system of the type mentioned at the beginning, which enables effective 6-sided processing of plate-shaped workpieces over their entire length, even without turning or folding the workpieces, in a particularly stable design with high accuracy.
  • the plate processing system contains a processing station for processing a plate-shaped workpiece and a support and positioning device for supporting and controlled displacement of the plate-shaped workpiece relative to the plate-shaped workpiece Processing station in a horizontal transport plane in the direction of a first linear axis.
  • the support and positioning device has two spaced support and positioning units for displacing the plate-shaped workpiece across a gap between the two support and positioning units.
  • the processing station contains a portal-like frame with an upper cross member arranged above the transport level and a lower cross member arranged below the transport level, with at least one processing unit movable in several axes on the upper and lower cross members of the portal-like frame with a motor-driven spindle for receiving a rotating tool is arranged.
  • the plate-shaped workpieces are accessible both from below and from above via the space between the two transport units.
  • the plate-shaped workpiece can be machined simultaneously with high precision along its entire length and also across its entire width from two opposite sides. This means that even large-format panels can be processed particularly effectively on all six sides with great precision.
  • the portal-like frame with the upper and lower cross members has a high level of rigidity, so that all-round processing can be carried out with great precision by the processing units arranged on it. Both the trimming work on a raw board and all internal processing can be carried out with high dimensional accuracy.
  • the two support and positioning units arranged before and after the gap, viewed in the transport direction of the workpiece each have at least one circulating transport chain with support plates arranged on the outside for supporting the workpiece.
  • the two support and positioning units can also contain two or more mutually parallel rotating transport chains with support plates arranged on the outside for supporting the workpiece. This means that a particularly precise and stable support and positioning device can be achieved.
  • each support and positioning unit are expediently guided on a frame-shaped support via front and rear deflections and can be driven in rotation by a motor.
  • the frame-shaped supports of the support and positioning units can preferably be moved horizontally by drives in the direction of the first linear axis.
  • the space between the support and positioning units can be changed or the distance between the support and positioning units can be optimally adjusted and adapted to the respective processing task.
  • the distance between the support and positioning units can be set between 600 mm and 1900 mm.
  • the transport chains can be guided by inner and outer lateral guide rollers and inner guide rollers arranged on the inside on horizontal inner guide rails and outer guide rails parallel to them.
  • the horizontal inner and outer guide rails are expediently arranged on the top of the frame-shaped support in such a way that a transport chain is guided with its inner and outer side guide rollers on the top sides of the horizontal inner and outer guide rails and with its inner guide rollers between the inner and outer guide rails.
  • horizontal support rollers lying transversely to the feed direction of the workpiece can be arranged at the ends of the frame-shaped supports facing the gap to support the workpieces at the gap.
  • a pressure unit with height-adjustable pressure elements for pressing the workpiece onto the support plates of the transport chains can be arranged on each of the two support and positioning units.
  • the pressure units can contain a stationary part with a fixed first frame and a movable part with a second frame arranged on the carrier and adjustable with this in the direction of the first linear axis.
  • First pressure elements and second pressure elements designed as pressure rollers and adjustable in height can be arranged on the first frame and the second frame.
  • the processing unit arranged on the upper cross member can be moved via an upper cross slide in a second linear axis perpendicular to the first linear axis and a third linear axis perpendicular to the first and second linear axes and can be rotated about two axes of rotation.
  • the processing unit arranged on the lower cross member can be moved via a lower cross slide in a second linear axis perpendicular to the first linear axis and a third linear axis perpendicular to the first and second linear axes.
  • Other or additional processing units or processing units can also be arranged on the lower cross member.
  • the panel processing system shown in a front view, a side view and a top view is designed to finish processing large-format panel-shaped wooden components from all 6 sides without turning or folding the components. Such a panel processing system can be used, for example, to produce fully processed wall, roof or ceiling elements for timber construction.
  • the plate processing system shown contains a processing station 1 and a support and Positioning device 2, through which a plate-shaped workpiece 3 can be moved in a path-controlled or controlled manner relative to the processing station 1 in a horizontal transport plane 4 in the direction of a first linear axis 5 (X axis).
  • the support and positioning device 2 consists of two support and positioning units 7 and 8 spaced apart from one another over a gap 6, through which the plate-shaped workpiece 3 can be moved across the gap 6.
  • the processing station 1 has a portal-like frame 9 with a horizontal upper cross member 10 arranged above the transport level 4 and a horizontal lower cross member 11 arranged below the transport level 4.
  • An upper processing unit 12, designed here as a multi-axis unit, is arranged on the upper horizontal cross member 10, which is arranged at right angles to the first linear axis 5 and spans the workpiece 3, and a first lower processing unit 13, also designed as a multi-axis unit, is arranged on the lower cross member 11.
  • the upper processing unit 12 arranged on the upper cross member 10 contains an upper cross slide with an upper horizontal slide 16 which is guided in a horizontally displaceable manner on a side surface of the cross member 10 via horizontal upper guide rails 14 in a second linear axis 15 (Y axis) perpendicular to the first linear axis 5 and an upper vertical slide 18 which is vertically displaceable on the horizontal slide 16 in a third linear axis 17 (Z axis) perpendicular to the first and second linear axes 5 and 15.
  • On the upper vertical slide 18 there is a downwardly projecting, fork-shaped support 19 about a vertical first axis of rotation 20 arranged rotatably.
  • the processing unit 21 has a housing 23 with a spindle 24 which is rotatable and rotationally driven within a housing 23 about a longitudinal axis of the housing 23 and for receiving a milling cutter, drill or other rotating tool.
  • the processing unit 21 therefore has a directly driven spindle 24 with an integrated tool interface.
  • the first lower processing unit 13 which is designed here as a 3-axis unit, is arranged on a side surface of the lower horizontal cross member 11 which is perpendicular to the first linear axis 5 and which faces the gap 6.
  • the first one below Processing unit 13 contains a lower cross slide with a lower horizontal slide 26 which is horizontally displaceably guided on a side surface of the lower cross member 11 via horizontal lower guide rails 25 in a second linear axis 15 (Y axis) perpendicular to the first linear axis 5 and one on the horizontal slide 26 in one the first and second linear axes 5 and 15 right-angled third linear axis 17 (Z axis) vertically displaceable lower vertical slide 27.
  • a processing unit 28 also designed as a motor spindle, with a rotationally driven and upwardly open spindle 29 for receiving a milling cutter , drill or other rotating tool.
  • a second lower processing unit 30 designed as a sawing unit is also guided in a displaceable manner in the direction of the second linear axis 15 via the guide rails 25. Further processing units can also be arranged on the lower cross member 11. Deep hole drilling units 32 can also optionally be attached to a further lower cross member 31 that is offset parallel to the lower cross member 11.
  • Two tool changers 33 and 34 are arranged on the two side walls of the portal-like frame for automatic tool changing.
  • the first tool changer 33 is designed for smaller tools, while the second tool changer 34 is designed for large tools.
  • Various tools can be exchanged using the pick-up principle via the respective processing units 12, 13 and 30.
  • the lower processing units 13 and 30 are arranged in a pit 35, while the portal-like frame 9 of the processing station 1 and the two support and positioning units 7 and 8 of the support and positioning device 2 can be arranged on a hall floor 36.
  • the portal-like frame 9 of the processing station 1 and the two support and positioning units 7 and 8 of the support and positioning device 2 can also be arranged on bases 37 and 38 made of concrete or the like, as shown in Figure 4 is shown.
  • the individual chain links 43 of the transport chains 39 have on their outside a support plate 44 that can be replaced if necessary for supporting the plate-shaped workpiece 3.
  • the support plates 44 can consist of a dimensionally stable and wear-resistant plastic with correspondingly high friction.
  • Each of the transport chains 39 is guided by inner and outer lateral guide rollers 45 and 46 and inner guide rollers 47 arranged on the inside on a horizontal inner guide rail 48 and a parallel outer guide rail 49 on the top of the frame-shaped support 40.
  • the guide rails 48 and 49 are arranged on the top of the frame-shaped support 40 in such a way that a transport chain 39 with its inner and outer lateral guide rollers 45 and 46 on the top of the inner guide rail 48 and the outer guide rail 49 parallel to it and with the other inside guide rollers 47 is guided between the two guide rails 48 and 49.
  • the transport plane 4 for the displacement of the workpiece 3 in the direction of the X axis is defined by the upper support plates 44 on the upper run of the transport chains 39.
  • the frame-shaped supports 40 of both support and positioning units 7 and 8 are arranged to support the workpiece 3 at the gap 6.
  • the diameter of the support rollers 50 is exactly adapted to the height of the upper support plates 44 on the upper run of the transport chains 39, so that the workpiece 3 is still supported but not lifted by the support rollers 50 when it is transported from one support and positioning unit 7 and 8 to the other .
  • the frame-shaped supports 40 of the support and positioning units 7 and 8 are adjustable in the X direction, so that the distance between the two support and positioning units 7 and 8 can be changed and adjusted if necessary.
  • measuring devices 51 for detecting the feed movement of the workpiece 3 are arranged. These instruct you a belt or a chain guided over deflection rollers on a carrier, a pressure device which moves with the belt or chain for pressing the belt or chain against the underside of the workpiece 3 and a sensor for detecting the movement of the belt or chain. By moving the pressure elements, the belt or chain can be pressed against the workpiece 3 to achieve a slip-free connection, without sliding friction occurring between the pressure element and the belt or chain. Details of the measuring device are in the DE 10 2013 104 241 A1 described in detail. Reference is expressly made to this publication with regard to the features of the measuring device.
  • FIG. 6 On the two essentially identically constructed support and positioning units 7 and 8 are in Figure 6 particularly clearly visible pressure units 52 with pressure elements 53 and 54 arranged in a height-adjustable manner above the transport chains 39 for pressing a workpiece 3 onto the support plates 44 of the transport chains 39.
  • the pressure units 52 are constructed in two parts and have a stationary part with a fixed first frame 55 and a traveling part with a second frame 56 arranged on the carrier 40 and displaceable together with it in the direction of the X-axis.
  • On the stationary first frame 55 several first pressure elements 53 designed as pressure rollers are arranged to be adjustable in height via first drives 57.
  • second pressure elements 54 which are also designed as pressure rollers, are arranged to be adjustable in height via second drives 58.
  • the frame-shaped supports 40 of the two support and positioning units 7 and 8 are over in Figure 1 shown third drives 59 can be moved horizontally in the direction of the first linear axis 5. This allows the distance between the two support and positioning units 7 and 8 to be adjusted to adapt to the respective processing tasks and to ensure that the support is positioned as close as possible to the tool.
  • Lateral supports 60 designed as roller conveyors can be arranged on the two long sides of the frame-shaped support 40.
  • the horizontal supports 60 are not absolutely necessary since the workpiece 3 rests on the upper support plates 44 of the transport chains 39 and the rotatable rollers of the supports 60, which are designed as roller conveyors, are slightly offset downwards relative to the support plates 44 and thus primarily serve as security.
  • both the trimming work on a raw plate and all internal processing can be carried out with high precision, even without complex turning or folding of the plate-shaped workpieces.
