Definitions

  • the present invention relates to a device for cutting metal sheets and for stacking the separated metal sheet sections.
  • the device has sheet metal scissors with a sheet metal feed table, on the rear edge of which a fixed lower knife is arranged, which cooperates with an upper knife pivotably mounted between two side stands.
  • a support device which is displaceable in its plane perpendicular to the cutting members is arranged behind the cutting point, and a height-adjustable lifting table is arranged beneath it, which takes up the separated sheet metal sections after the support device has been withdrawn.
  • a stop is provided against which the edge of the sheet to be cut rests so as to determine the width of the sheet section. After the cut, the severed sheet metal strip lies on the support device and then, after retracting it, falls down onto a stacking surface, so that a stack of sheet metal sections is gradually formed.
  • this stack is stacked evenly and orderly in order to avoid subsequent, time-consuming and tedious manual sorting of the stack. This can be achieved by keeping the falling distance of the sheet metal section as small as possible.
  • the height-adjustable lift table serves this purpose.
  • a pallet can be used as a stacking surface, which is arranged on the lifting table.
  • the lifting table is located directly behind the lower knife and is moved into an upper end position at the start of work, so that the surface of the pallet lies below the plane of the sheet feeding table by a certain small amount, depending on the thickness of the sheets to be cut.
  • the lifting table is lowered somewhat in order to bring the surface of the stack formed in this way back some distance below the level of the feed table. This process is repeated until the lifting table has reached its lower end position or the stack has reached its intended height.
  • the lowering of the lifting table can be done either manually or automatically, for example with the help of a light barrier, step by step or continuously. This ensures that the separated sheet metal sections always cover only a small distance in free fall, so that a clean, even stack is formed.
  • this device is characterized in that the lifting table is stationary and longer than the lower knife and extends from the one side stand of the scissors along the cutting point through a recess of the other side stand, which recess is the lifting and lowering of the lifting table allowed, and a stacking and transporting element which can be moved transversely to the sheet metal feed for forming several sheet metal stacks is provided on the lifting table.
  • the surface of the lifting table can be provided with a roller conveyor and a conventional pallet can be placed on this roller conveyor.
  • a pair of guillotine shears is shown, which is provided with a sheet metal feed table 1, on the rear edge of which a fixed lower knife 2 is attached. These parts are stored in a machine frame 3 which is delimited on both sides by side walls 4 and 5.
  • a hold-down device 6 ensures that a metal sheet to be cut cannot move during the cut.
  • the fixed lower knife 2 works together with an upper knife 7 which is mounted in a knife bar 9 which can be pivoted about an axis 8.
  • a displaceable support device 10 is arranged, which is also provided with displaceable stops 11.
  • the support device can consist of a number of parallel rods, which extend away from the lower knife 2 extend. The function of the support device and the stops will be discussed in more detail below.
  • One side wall 5, in FIGS. 2 and 3, is perforated, so that a free passage 12 is formed behind the lower knife 2.
  • the height of the passage 12 corresponds approximately to the height of the feed table 1.
  • a lifting table 13 is arranged behind the cutting point, the design of which is not discussed in detail here. As can be seen from FIGS. 2 and 3, it extends from the continuous side wall 4 across the width of the guillotine shears and through the passage 12 somewhat beyond the shears.
  • On its upper side it is provided with a number of rollers 14 which are rotatable about axes running perpendicular to the lower knife 2.
  • a pallet 15 placed on the roller conveyor thus formed can thus be displaced parallel to the lower knife 2, specifically within the scissors along the knife 2 and out of the scissors, through the passage 12. The pallet 15 is used to hold stacks 16 of separated sheet metal sections.
  • the device works as follows:
  • the lifting table 13 with the pallet 15 attached is raised to an upper end position in which the surface of the pallet 15 lies just below the cutting point or below the support device 10. Then the sheet of metal to be cut is inserted until its edge lies against the preset stop 11.
  • the sheet metal section to be separated is supported by the support device 10. After pressing the hold-down device 6 the cut with the help of the two knives 2 and 7, so that the separated sheet metal section 17 a lies on the support device 10. After the cut, the support device 10 is pulled backwards, the stop 11 remaining in place. As a result, the sheet metal section 17a falls down onto the pallet 15, whereby it only has to cover a short distance in free fall because the pallet 15 has been brought almost to the height of the knife 2 by the lifting table 13. The support device 10 is then brought forward again into its starting position, so that the next sheet metal section can be supported and separated in a corresponding manner.
  • each cut sheet section 17a only has to cover an optimally short distance in free fall, so that a neatly stacked, orderly stack 16 is produced.
  • the second stack 16a is now piled up until it has reached its intended height. Since the lifting table 13 is then again in its lower position, the pallet 15 can again be laterally displaced by the width of the stack 16a plus the thickness of the side wall 5 in order to enable the lifting table 13 to be raised again.
  • several stacks 16 can be stacked next to one another on the pallet 15, whereby it is always ensured that the sheet metal sections cover only a short distance in free fall, so that neat, cleanly layered stacks 16 are created. This ensures optimal use of space on the pallet 15. As soon as the pallet 15 is full, it is pulled out of the guillotine shears on the roller conveyor and can e.g. taken over by a forklift and fed to further processing.
  • Fig. 4 A separated sheet metal section lies on the support device 10 and touches the stop 11 with its rear edge.
  • the pallet 15 is still empty.
  • the support device 10 is now moved backwards in the direction of the arrow, the stop 11 remaining in place.
  • Fig. 5 The support device 10 is in its rear end position and the sheet metal section 17b has fallen onto the pallet 15.
  • Fig. 6 The support device 10 has been moved forward again and the next sheet metal section 17c has been separated. It lies against the stop 11 and rests on the support device 10. This is now moved together with the stop 11 in the direction of the arrow to the rear.
  • Fig. 7 The sheet metal section 17c is now over a free location on the pallet 15, immediately behind the section 17b. The stop 11 is stopped, but the support device 10 is moved further in the direction of the arrow.
  • Fig. 8 The support device 10 has been moved completely to the rear and the section 17c has fallen onto the pallet 15, where it rests behind the section 17b.
  • Fig. 9 support device and stop have been returned to their starting position and the next, separated sheet metal section 17d lies on the support device 10. This is moved together with the stop 11 in the direction of the arrow towards the rear.
  • Fig. 10 As soon as a free place on the pallet 15 is reached, the stop 11 is stopped, but the support device is moved further back.
  • Fig. 11 The support device 10 is in its rear end position and the section 17d has fallen onto the pallet 15, where it lies behind the section 17c.
  • Fig. 12 The support device 10 together with the stop 11 has been brought back to the starting position. The next, separated sheet metal section 17e lies on the support device.
  • Fig. 13 The support device 10 together with the stop 11 has been moved backwards until the section 17e has reached the last position on the pallet 15 that is still free in this stack row. The stop 11 is now stopped.
  • Fig. 14 The support device 10 has been moved further back with the stop 11 stationary and the section 17e has fallen onto the pallet 15, where it rests behind the section 17d.
  • the whole cycle begins anew by placing the next sheet metal section on sheet section 17b already lying on pallet 15, the following sheet metal section on section 17c and so on.
  • the four stacks 16 gradually grow, and the pallet 15, which is placed on the roller conveyor of the lifting table 13, is lowered somewhat.
  • the pallet 15 can be moved laterally out of the guillotine shears, as has already been described above, and the next stack row can be set up in a corresponding manner.
  • This procedure allows an optimal use of the space available on the pallet 15, whereby it is always ensured that cleanly stacked stacks 16 are formed, since the sheet metal sections only have to cover a short distance in free fall.
  • the movements of the support device 10 and stop 11 can be controlled automatically, e.g. under the influence of an electronic NC control unit. If necessary, this can also be used to control the lifting and lowering movement of the lifting table 13.
  • the proposed device not only allows optimum use of space on the pallet 15 with simultaneous, orderly stacking, but also enables fast, safe work, since the subsequent manual rearrangement and straightening of the stack 16 can be completely dispensed with.
