  • the drilling and milling machine which has been generally indicated by the reference number 1, comprises a supporting device, designed for supporting one or more panels or workpieces to be processed, said supporting device comprising roller assemblies 2 including a plurality of idle rollers 3, coupled to a supporting framework 4.
  • the supporting device is adapted to support a workpiece, not shown, which typically comprises a panel to which metal elements or fixtures must be applied by an operating head 5 which can be displaced on a cross guide 6 traversing the top of the supporting device.
  • the operating head 5 comprises, in a per se known manner, a tool exchanging device 7, a screwing on and off device 8, an insert supplying device 9 for supplying insert elements, not specifically shown, to be applied to the workpiece.
  • the subject machine On a working bench 10, in a working position of the operating head 5, the subject machine further comprises a clamping device 11 for clamping the workpiece to be processed.
  • Said clamping device 11 comprises an aligning element, arranged in front of the bench 10, on the other side of the workpiece supporting device, and comprises moreover a plate 12 including a plurality of transversally movable vertical axis rollers 13, which can be driven in the longitudinal direction of the supporting device 2, so as to clamp the workpiece in its working position, as counterurged by guiding rollers 14 and 15 of a translating device 16.
  • the translating or deriving device 16 is designed for driving the workpiece on the roller assemblies, or transport device 2, and comprises a longitudinally extending guide 17 which extends along a side of the transport device and comprises guide rollers, respectively 14 having a vertical axis and 15 having a horizontal axis, adapted to respectively engage the outer edge and bottom edge of the workpiece.
  • the longitudinal guide 17 slidably supports a floating suction cup device 18, designed for sliding along the guide 17 and for clamping the workpiece to drive it, along the roller assemblies, to a set working position, and being furthermore designed for unloading said workpiece.
  • the floating suction cup device 18 which is shown in a more detailed manner in figures 3-6, comprises a suction cup assembly 19, supported by a slide 20 which can be slidably driven along the mentioned longitudinal guide 17.
  • the driving of the slide 20 and, accordingly, of the suction cup assembly 19 along the guide 17 is controlled by a motor-reducing unit 21, driving a belt coupled to said slide 20.
  • the suction cup assembly 19 is supported by said slide 20 through a guide carriage 23, so as to be vertically displaced with respect to said slide, as controlled by a pneumatic piston 22.
  • the vertical displacement of the suction cup assembly 19 allows the suction cups included therein to be moved toward the bottom surface of the piece.
  • the suction cup assembly is coupled to the vertical guide carriage 23 through a horizontal guide 24 designed for allowing the suction cup assembly to be horizontally and transversely driven with respect to the workpiece longitudinal driving direction.
  • the suction cup assembly is centered by a pair of spring urged pusher elements 25, which essentially comprise a small plunger operating against a coaxial coil spring, said pusher elements being adapted to hold at a centered position said suction cup assembly, while allowing, owing to the elastic properties of the spring, a slight cross displacement, in both directions with respect to the middle longitudinal line, in order to compensate for possible workpiece unevennesses, due, for example, to a non perfectly rectilinear edge thereof.
  • the suction cup assembly 19 comprises, in this embodiment, two suction cups 26, but, as it should be apparent to one skilled in the art, it could be also comprise a single suction cup or three or more suction cups, depending on requirements.
  • the suction cup assembly 19 comprises a double tray construction 27, designed for defining two recesses and comprising an edge 32 including a gasket 28 made of rubber or any other suitable resilient materials.
  • a ball shutter element 29 is provided, said ball shutter element comprising a ball 30 adapted to obstruct a hole, as said ball is urged by an urging spring 31.
  • the shutter element 29, as shown, is coupled to a suction source, or vacuum source through suitable ducts 33 thereby, as a panel is contacted by the suction cup assembly, the lower surface of said panel will be caused to bear on said gasket 28, thereby deforming it so as to contact the ball 30 which will be downward driven, thereby partially freeing the hole and providing a negative pressure in the cavity of the suction cup 26.
  • said workpiece or panel Upon having processed the workpiece and having removed it from the working station, said workpiece or panel will be disengaged by lowering the suction cup assembly 19, by a control piston 22.
  • the suction cup assembly 19 is adapted to engage a workpiece and drive it, along the roller assemblies, to the working or processing bench.
  • the suction cup assembly will drive the workpiece rightward with reference to figure 1, to the following unloading position thereof.
  • said suction cup assembly 19 comprises a double chamber, so as to allow the individual suction cups 26 thereof to be supplied in a mutual independent manner.
  • the operating speed and accelerations, as the workpiece is driven, are suitable adjusted to allow an accurate locating of the workpiece to a set working position, and in order to prevent the workpiece from being damaged.
  • the workpiece driving adjusting is performed by a driving control system, comprises a cam assembly or set 34, controlling three microswitches.
  • a first microswitch reduces the workpiece feeding speed
  • a second microswitch controls the assembly so as to be properly located at a starting position thereof
  • a third microswitch operates as a safety control element, i.e. a limit switch, operating to stop the assembly in the case in which limit positions would be exceeded.
  • the driving control system comprises moreover a pair of wheel pusher elements 35, designed for operating on the top surface of the work piece to hold it in its working position, in cooperation with a second pair of pusher wheel elements 36 of the plate aligner 12.
  • Each said pusher element 35 comprises a pair of photocells 37 and 38 provided for respectively detecting the inlet and outlet of the workpiece edge, in order to control the operation of the pusher elements.
  • the workpiece typically a wood or other material panel used for making furniture articles
  • the workpiece is caused to slide along said roller assemblies from a supplying or feeding position, at the left with reference to figure 1, to a working position at the operating head 5, by operating the suction cup assembly 19.
  • the latter affects only the bottom surface of the panel while leaving the side edges and top edge of the panel free.
  • the suction cup assembly 19 is raised and brought to contact the panel bottom surface, thereby automatically providing a negative pressure, through the above disclosed ball shutter elements.
  • the panel is brought to its working position, where on the panel are performed all the necessary processing operations, which are performed by the mentioned operating head.
  • the panel is driven by the suction cup assembly along the roller assembly, rightward with reference to figure 1, to an unloading position or a following processing station.
  • the machine according to the present invention provides, owing to the provision of the disclosed suction cup assembly, great advantages, since the perimetrical edges of the panel are left fully free, thereby preventing the panel from hindering further processing operations.
  • a further advantage of the machine according to the invention is that, owing to the specifically designed suction cup assembly, it is possible to accurately drive the panel without damaging it, owing to the self-centering characteristics and self-adjusting properties of the assembly during the driving thereof.
  • the subject drilling and milling machine allows to easily apply metal elements and fixtures to the panels for forming the furniture pieces, in a manner which does not damage the panels or obstruct the processing steps.
  • the used materials as well as the contigent size and shapes, can be any, depending on requirements and the status of the art.
