  • the charging device 13 may comprise two or more bearing means 7.
  • This bearing means 7 is arranged in this preferred embodiment on a machine bed 11 of a processing device, not shown. This clarifies in particular that different Processing device with the invention
  • Feeding device 13 can be equipped.
  • the bearing means 7 serves as a workpiece memory (a) for workpiece blank 6 and (b) for finished workpiece 12.
  • Finished workpiece 12 in this context does not mean that essentially no further processing steps are to be performed, but that on the processing device, which of the loading device according to the invention is loaded, no further processing steps are more necessary.
  • workpiece blank 6 does not mean that they have not yet undergone processing, but that no processing has been carried out on the processing device which is fed by the feeding device according to the invention.
  • Work piece raw parts can be stored in the storage means 7 at a first position 14 and finished workpieces 12 can be stored in the storage means 7 at a second position 15. These different positions allow independent access to them, meaning that access to both of these stored workpiece types is possible independently.
  • stops 1 are also provided on the machine bed 11. This allows a straightforward alignment against these attacks. Thus, a user can move the bearing means 7 as far as the stop against the stop 1. This saves working time and increases the positioning accuracy. Furthermore, a plurality of brackets 2 is provided between the machine bed 11 and the bearing means 7. These consoles thus accommodate the storage means 7 and can be height adjustable. In this illustrated embodiment of the invention
  • the bearing means 7 is formed as a storage box with at least one side wall.
  • the exact design of this storage box which may be a box, for example, is arbitrary to choose, to minimize costs can be used, for example, to a standard size, which is large enough to accommodate workpieces at various positions and deep enough to accommodate a suitable number of workpieces. It may also be advantageous to select the combination of console 2 and bearing means 7 so as to enable the bearing means 7 to be lifted by means of a suitable transport means such as a forklift.
  • the storage means 7 can be removed for any lot size. This is particularly dependent on the size of the workpiece blank 6 used or the finished workpieces 12 and a total number of workpieces to be machined.
  • the storage means is in particular also able to be removed for a lot size 1.
  • a height of the side wall of the bearing means 7 may be selected such that a lifting operation of a workpiece blank 6 at the first position 13 causes the gap between a lower edge of the raised workpiece and the upper edge of the bearing means 7 to be smaller than a thickness of the workpiece.
  • the workpiece raw parts 6 accommodated in addition to a first workpiece raw part 6 are thus stripped off in a further method, that is to say in the case of a further lateral movement of the gripping device 10.
  • This stripping is done here by a retention of the additional workpiece raw parts 6 through the edge of the bearing means. 7 It is also possible to carry out the bearing means 7 in two parts, wherein the first position 14 and the second position 15 are distributed.

  • the loading device further comprises a gripping device 10.
  • This gripping device has the task of moving workpieces between the bearing means 7 and a processing device, not shown.
  • the gripping device 10 comprises a suction gripping unit 8, which can suck in workpieces and subsequently move them. The process of suction thus provides a process which establishes a connection between the suction gripping unit 8 and the workpiece.
  • the gripping device 10 also has a positioning ⁇ device 9. This positioning device 9 establishes a relative movement between the bearing means 7 and the suction gripping unit 8. Since, in turn, the workpiece can be sucked in on the suction gripping unit 8, a relative movement is thus produced between the bearing means 7 and the workpiece, and a loading of the processing device is made possible.
  • the positioning device 9 provides in this embodiment, a change in the position of the suction gripping unit 8 in three independent spatial directions. Shown in Fig. 1 are the orthogonal axes Z and X, in which case the Z-axis is a direction along the direction of gravity. Thus, the Sauggreifaggregat can first lift a workpiece in the Z-axis, and then initiate a movement on the XY plane to process the workpiece as needed.
  • the charging device 13 thus enables a method for automatic loading of a plate-shaped workpiece, which is preferably at least partially formed of wood, wood material, plastic or the like.
  • This method has the step that a workpiece raw part 6 is received by the gripping device 10.
  • This receiving process may begin with the suction gripping unit 8 being positioned directly above such a workpiece blank 6 without a workpiece picked up thereon.
  • the to be taken workpiece blank 6 is, in the case that several Maschinen simplifyrohmaschine are arranged one above the other, the top of this Maschinen simplifyrohmaschine.
  • the positioning is done according to this embodiment in the XY plane.
  • the suction gripping unit 8 has a sufficiently large overlap with the Maschinen thoroughlyrohteil 6 that this can be taken.
  • the Sauggreifaggregat 8 is lowered over the Maschinen sparohteil 6 in the Z-axis. This happens until a connection between the suction gripping unit 8 and the workpiece blank 6 is produced.
  • This step of lowering can either be monitored by sensors, in particular distance sensors, in real time, stopped manually or predefined.
  • the suction gripping unit 8 preferably begins with the suction of the workpiece blank 6.
  • This suction can be implemented in such a way that air is extracted from suction cups, thus producing a negative pressure or almost a vacuum.
  • a frictional connection between the suction gripping unit 8 and the Maschinen Swissrohteil 6 is produced.
  • the suction gripping unit 8 and the Maschinen Swissrohteil 6 can be transported together.
  • Fig. 1 such a transport state is shown with the workpiece 5.
  • the workpiece 5 is lifted together with the Sauggreifaggregat 8, that is moved in the Z direction.
