Definitions

  • the invention relates to a plate processing plant according to the preamble of claim 1.
  • the plate-shaped workpieces are fed by a first transport device, namely a program pusher with existing collets on this, from a feed table arranged in or below a machine table saw.
  • a discharge table is present, on which an operator stands, the manually machined, so split workpiece from the machine table to the unloading table.
  • a first transport device namely a program pusher with existing collets on this
  • a feed table arranged in or below a machine table saw.
  • a discharge table is present, on which an operator stands, the manually machined, so split workpiece from the machine table to the unloading table.
  • An example of this is the DE 10 2010 010 746 A1 .
  • a known from the market program slider includes a Ausschubvorraum that is activated when pushing the last workpiece on the unloading table. Furthermore, there is usually a waste flap in the area of the discharge table of an automatic plant. Also known for example from the DE 10 2005 020 979 A1 to use a lower finger of a collet to push off a workpiece. Finally, the reveals EP 2 422 944 A1 a largely automatic panel sizing unit.
  • the present invention has an object to provide a plate processing plant, which works very efficiently and in which the safety of the operator is particularly high.
  • the plate processing installation has a second transport device, which is separate from the first transport device and can transport a workpiece lying on the machine table at least in regions from the machine table in a direction away from the feed table by means of an engagement section.
  • “separate” means, for example, that the second transport device is structurally independent of the first transport device and insofar can preferably be operated completely independently of this.
  • the second transport device has a rest position, in which the engaging portion is arranged below the top of the feed table and the machine table. Furthermore, it has an operating position in which the engaging portion is arranged at least partially above the top of the feed table and the machine table.
  • the plate processing system according to the invention has the advantage that even narrow strips that lie on the machine table, no longer have to be manually pulled away by an operator from the machine table, but automatically be moved away from the second transport from the machine table in the direction of the unloading table. As a result, it is no longer necessary for the first transport device to move such a workpiece from the machine table in the direction of the removal table.
  • the first transport device can already drive back again and grab a new workpiece and transport it to the machine table, while the second transport device moves the workpiece lying on the machine table, for example, in the direction of the removal table.
  • the second transport device moves the workpiece lying on the machine table, for example, in the direction of the removal table.
  • the second transport device comprise at least one base section which is movable in and counter to the transport direction and at least one slide section which is at least indirectly fixed and vertically movable and which belongs to or forms the engagement section.
  • Such a second transport device is structurally simple and works very reliable.
  • An engaging portion formed as a slider portion is basically the simplest configuration because, for example, no clamping mechanism or the like is required.
  • the slide portion has at least one recess through which, when the second transport device is in the rest position, a support element of the machine table or the feed table can pass.
  • a support element of the machine table or the feed table can remain unchanged, so that the second transport device can also be retrofitted, for example, to existing plate processing systems.
  • a support element is understood to mean, for example, an air outlet nozzle of an air cushion table or a roller of a roller table.
  • the slider portion comprises a support arm which is pivotally mounted on the base portion and kinematically coupled to a stationary control portion such that it is moved upward in a transport direction of the base portion and downward in a direction of movement of the base portion ,
  • a support arm which is pivotally mounted on the base portion and kinematically coupled to a stationary control portion such that it is moved upward in a transport direction of the base portion and downward in a direction of movement of the base portion .
  • the stationary tax area comprises a backdrop.
  • a backdrop is inexpensive and very robust.
  • the base section is connected to a flexible drive element, in particular a belt or a chain, which is driven by a drive, in particular an electric motor. Again, this is an inexpensive and extremely robust type of drive for the movement of the base section.
  • the second transport device has at least two partial transport devices arranged side by side in the transport direction and operated in the same direction, each having a movable base section and a respective pivotable holding arm.
  • the possible area at which the second transport device acts on the workpiece is increased, whereby the force which, during transport of the workpiece by the second transport means on this Piece is applied, is reduced.
  • this embodiment makes the transport of the workpiece by the second conveyor more reliable.
  • one of the sub-transport means comprises a drive which is coupled by means of a coupling means with another of the sub-transport means so that it also drives the other sub-transport means.
  • At least two partial transport devices have a common slide portion with two holding arms, by means of which the slide portion is pivotally attached to the base portions of the partial transport means.
  • Such a slide portion is therefore basically linear in shape and thus allows a distributed over a larger area of a rear edge of the workpiece attacking the slide portion, whereby damage to the workpiece can be avoided.
  • the second transport device has at least one stop portion, on which a workpiece moved by the first transport device in the transport direction can be applied, which in the rest position of Transport device is arranged below the top of the feed table and the machine table, and which is arranged in the operating position of the transport device at least partially above the top of the feed table and the machine table.
  • the second transport device is assigned an additional function: It also serves as a stop for aligning a plate-shaped workpiece, which is transported by the first transport device from the feed in the direction of the machine table.
  • the plate-shaped workpiece is aligned with its front edge seen in the transport direction exactly parallel to a cutting line when it rests against the abutment portion of the second transport device.
  • the collets a program slider of the first transport device reliably approach the rear edge of the workpiece viewed in the transport direction and can grab this.
  • the stop section is arranged on the holding arm or on the holding arms. This is particularly simple and inexpensive to implement.
  • the stop section is formed by a vertical edge formed on the holding arm and vertical in the operating position of the second transport device. This is maximally inexpensive and very robust.
  • the second transport device has at least one lifting element with which an at least partially located in a kerf remaining workpiece can be lifted out of the kerf.
  • the reliability of the panel splitter is further improved because even very narrow residual workpieces that can get into an unfavorable case partially into the kerf, and therefore can not be easily detected and removed by the attacking section, are first raised from the shegeschlitz, so that They can then be reliably transported away.
  • the lifting element comprises a lifting section having an inclined upper side, which is received in the operating position of the second transport device in a groove running in the transport direction in the machine table.
  • This is a very easy to implement variant of a lifting element.
  • the collet grooves which are present anyway in a conventional machine table, can be used to receive the lifting section.
  • the lifting element can be arranged on an underside of the engaging portion at its projecting edge.
  • a plate processing plant as a whole carries the reference numeral 10. It comprises a machine table 12 which is elevated by means of feet 14 on a floor. In FIG. 1 To the right of the machine table 12 is a feed table 16 which is formed by a plurality of rollers 18.
  • To the plate processing system 10 also includes a left of the machine table 12 existing unloading table 20, which may be as well as the machine table 12, for example, designed as an air cushion table. It is understood that in FIG. 1 only part of the feed table 16 and only part of the unloading table 20 are shown in the drawing. Above the machine table 12 is a Pressure bar available, which is not shown in the drawing. This can be moved vertically and clamp a lying on the machine table 12 workpiece against this, whereby it is securely fixed during processing.
  • a panel saw In the panel processing system 10 is in the present case a panel saw. It therefore comprises a sawing device 22, which in the present case is designed as a under-counter circular saw with a vertical saw blade 24 and a horizontal axis of rotation 26 of the saw blade 24. Through a slot 28, the saw blade 24 can be moved upwardly over an upper surface 30 of the machine table 12, so that it can machine a lying on the machine table 12 workpiece.
  • the tops of the machine table 12, feed table 16 and unloading table 20 are present all on the same level. This is in FIG. 1 indicated by a dashed line 30.
  • the plate processing system 10 includes a first transport device 32, which can transport a workpiece 34 from the feed table 16 in the direction of the machine table 12 (transport direction 36).
  • This first transport device 32 comprises a program pusher 38 which is perpendicular to the plane of the drawing FIG. 1 extends and which can be moved by a motor drive, not shown, both in the transport direction 36 and in the opposite direction.
  • a program pusher 38 On the program pusher 38 a plurality of collets 40 is fixed, which jaws (without reference numerals) have, between which a rear edge 42 of the workpiece 34 can be clamped.
  • FIG. 1 is drawn by the second transport device 44 only designed as a slide portion engaging portion 46 and a support arm 48 which the slider portion 46 with a in FIG. 1 not subscribed base section connects.
  • the slide portion 46 is rigidly connected to the holding arm 48, the holding arm 48 relative to the base portion, however, pivotally connected.
  • FIG. 1 the second transport device 44 is shown in a rest position, in which the slide portion 46 is disposed below the top 30 of the feed table 16 and the machine table 12.
  • the workpiece 34 and the first transport device 32 are both located in a relatively right region of the feed table 16.
  • the second transport device 44 is no longer in the rest position but in a first operating position, in which the slide portion 46 above the top 30 of the feed table 16 and the machine table 12 is arranged. How out FIG. 3 it can be seen, the second transport device 44 was there moved by motor in the transport direction 36, so that the slider portion 46 came into contact with the rear edge 42 of the workpiece 34, and then the workpiece 34 has been pushed from the machine table 12 to the unloading table 20. The slider portion 46 and the entire second conveyor 44 are located in FIG. 3 Thus, in a second operating position, in which the slide portion 46 is also disposed above the top 30 of the feed table 16 and the machine table 12, but was additionally moved in the transport direction 36 for pushing out of the workpiece 34 on the unloading table 20.
  • the function of the second transport device 44 is particularly helpful, for example, in a so-called scratch cut at a rear edge 42 of the workpiece 34.
  • a scratch cut the workpiece is positioned relative to the saw blade 24 such that a material width at the rear edge 42 is removed by the sawing process, which is smaller than the thickness of the saw blade 24.
  • the rear edge 42 is processed. This is only possible if after fixing the workpiece by the pressure bar and before machining the collets 40 have released the rear edge 42, the workpiece 34 is thus no longer held by the program pusher 38 during processing by the saw 22.
  • the machined workpiece 34 can be moved by the second transport device 44 in the direction of the removal table 20, while the first transport device 32 already moves backwards against the transport direction 36 is to get another workpiece and to move towards the machine table 12 out.
  • the operator who is usually standing in the area of the removal table 20, no longer has to move into the area of the machine table 12 to pull the workpiece 34 from there onto the removal table 20.
  • the reliability of the operator is improved.
  • "Unmanned" Plattenetzteilanlagen which are set up for an at least largely or even completely automatic operation, considerable time is saved.
  • the slide portion 46 as elongated and perpendicular to the plane of the Figures 1-3 extending beam is formed, which has approximately the cross section of a downwardly open C-profile.
