Definitions

  • the present invention relates to angled shears with a feed table and associated longitudinal and transverse shears. There are also longitudinal and transverse feeds, as well as guide devices, together with a rotating device arranged above the feed table.
  • Angled scissors with an L-shaped table are already known, which angular scissors have a longitudinal knife and a transverse knife, as well as feed means arranged between them in the longitudinal and transverse directions.
  • the purpose of such angled scissors is to quickly and reliably dismantle metal sheets into individual blanks.
  • Such a device according to the preamble of claim 1 is known for example from GB-A-2001272.
  • an angle shear which allows the automatic cutting of metal sheets from stacks and can be used universally for large panels cut precisely at right angles, as well as for strips and smaller boards.
  • a high cutting accuracy should be guaranteed.
  • the cutting of boards should be possible in one pass.
  • the angle scissors of the type mentioned at the outset which are suitable for this purpose are defined by the features listed in claim 1.
  • a stacking device can expediently be provided both behind the longitudinal shears and behind the cross shears be, wherein at least one stacking device consists of a forward and backward movable conveyor belt which can be lowered and raised with the scissors movement.
  • the longitudinal direction is designated with the Y direction and the transverse direction with the X direction.
  • the angular shear has a longitudinal shear 1 extending in the Y direction and a transverse shear perpendicular to it, the longitudinal shear having a longitudinal knife 3 and the transverse shear having a transverse knife 4.
  • the longitudinal shear 1 and the cross shear 2 have a common hydraulic control 5 and are equipped with a scrap box 6 and 7, respectively.
  • the longitudinal scissors 1 and the cross scissors 2 are jointly provided with a feed table 8, on which, at the end remote from the longitudinal scissors 1, there is a lifting platform 9. Above the lift a suction head 11 can be raised and lowered and rotated on a suction head carriage 10.
  • the suction head carriage is slidably arranged on a cross member 34 above the feed table 8.
  • the parts 10, 11 and 34 together form a feeder for the metal sheet, which is directed in the stack by side and front stops, are arranged on the lifting platform 9.
  • the lifting platform 9 is designed in a known manner in such a way that it automatically goes up so far that the uppermost plate comes to lie on the level of the feed table 8.
  • the lowerable and rotatable suction head 11 grips the uppermost sheet metal plate on one side, bends the sheet metal slightly and lifts, after which the suction head slide 10 moves forward in the Y direction and pulls the sheet metal onto the feed table 8.
  • the feed table 8 is equipped with ball rollers (not shown).
  • the table 8 is provided with continuous grooves 12 which extend in the Y direction and in which Y-pliers 13 are arranged so that they can be lowered and raised. These can be used to grasp the edge of a sheet of metal. However, it is also possible for these Y pliers to jointly form a stop if the metal sheet is aligned in the X direction. Below the table 8 there is a crossbar 14 on which the Y-tongs are fastened and lowered. The crossbar 14 is arranged to be displaceable in the Y direction and forms the Y feed for the Y pliers 13. The entire control is carried out from a control panel 15.
  • X pliers 16 are provided above the table surface opposite the cross shear, which are also arranged on a common longitudinal beam 17 so as to be displaceable and positionable in the X direction.
  • the pliers 16 are located above the table surface 8 and can be raised and lowered accordingly to grip the sheet metal piece.
  • the longitudinal bar 17 is displaced along a guide bar 18 on which corresponding slide rails are arranged.
  • a conveyor belt 19 which runs in the Y direction and is guided over deflection shafts 20, 21.
  • the conveyor belt 19 is also connected to the pivotable housing 22 of the longitudinal knife 3.
  • the housing 22 pivots around the shaft 23, the arrangement being such that during the cutting movement, ie when pivoting counterclockwise, the conveyor belt 19 is also pivoted in the same sense and is thereby sunk under the table surface.
  • the upper run of the conveyor belt 19 is at the same height as the upper table surface of the feed table 8.
  • the conveyor belt 19 is pivoted downward with its end facing the longitudinal knife 3 in the manner described.
  • a stacker 24 At the other end of the conveyor belt is a stacker 24 with transverse conveyor rollers, the axes of which extend in the Y direction (not shown).
  • a conveyor belt 25 is also located behind the transverse knife 4 of the transverse shear 2, the upper run of which is sunk relative to the table surface.
  • An adjustable, known stop device 26 is provided in the table surface. Behind the conveyor belt 25 there is in turn a lifting platform 27 which is equipped with a roller conveyor 28. Above the runway 28 there is a stop 29 which can be adjusted with the aid of a guide 30 on a guide rod 31 which extends in the X direction.
  • Retractable side stops 32 and 33 are also arranged on the surface of the feed table 8.
  • the side stops 32, 33 are aligned and distributed within a surface in the longitudinal and transverse feed directions X and Y, which surface is delimited by the longitudinal scissors 1, cross scissors 2 and by the Y pliers 13 and the X pliers 16.
  • the side stops can be raised from the lowered position to the position of use, each have a roller against which the edge of the metal sheet to be guided comes into contact during use, the roller being preceded by a further swiveling pressure roller and a counter-holder arranged underneath. This pressure roller and the counter bracket form a clamping device for the metal sheet. In the one position of the pressure roller, the sheet metal plate can be moved between it and the counter-holder and in the second position the metal plate is clamped between the counter-holder and the pressure roller.
  • the row-by-side arrangement of the side stops ensures that the metal sheets can be guided along different side stops depending on their size and intended use, so that the formation of several stacks of sheet metal sections next to one another is made possible.
  • the sheet metal sections can thus be stored separately in several stacks and manipulation with the sheet metal sheets is also facilitated.
  • the turning device which can be moved lengthways and crossways above the work table and is equipped with the suction head, further facilitates manipulation.
  • the angle shear described has a sheet metal feed system which, as described, consists of a feed slide equipped with tongs in the X and Y directions.
  • the pliers are actuated hydraulically in a known manner and the pliers for the Y feed can be lowered below the table surface, while the pliers for the XV feed can be lifted up, so that the pliers can cross without collision in the lowered or raised position . If the table has to be rotated by the suction head, the pliers are in the lowered or raised position during this rotation, so that the table can be rotated freely.
  • the sheet of metal with the suction head 11 is placed on the feed table 8 with the aid of the suction head carriage 10.
  • the Y-tongs 13 then grip the corresponding sheet metal edge and push the sheet under the longitudinal knife 3 in the direction of the conveyor belt 19 until the strip width to be cut between the knife base and the tongs base is reached.
  • This is followed by longitudinal cutting, whereupon the cut strip is returned along the raised side stops 22, 23 with the aid of the conveyor belt, which is now operated in the opposite direction.
  • the X-tongs are used and grasp the strip, whereupon the cross-shear feeds in the X-direction.
  • the side stops 22, 23 in turn form a correct guide.
  • the boards are then cut and ejected onto the stacking station.
  • the Y-tongs move forward again, grasp the rest of the sheet, which is fed to the Y-tongs by the reverse conveyor belt.
  • the side stops 32 grip and guide on both sides right and left, while the side stops 33 guide or grip only on one side.
  • Boards are also cut in one pass, with the cut strip being shifted from the Y feed into one of the three liftable side guides 32, 33 after the longitudinal cut.
  • the side guide heads are equipped with guide rollers and pneumatic pinch rollers, which are used to advance the strip Guide the strip in the direction of the transverse shear and press it against the side guide rollers so that exactly right-angled cuts are made.
  • the Y-pliers are loosened and lowered under the table surface, while the strip is gripped by the X-pliers required according to the strip width and pushed through the cross-cutters to make the board cuts.
  • the side guides are arranged at three different distances perpendicular to the longitudinal shears and allow the ejection of boards at three different locations that can be selected by the control system, so that depending on the board format it is possible to create up to three stacks side by side.
  • the conveyor belt behind the longitudinal scissors also serves as a stacking device and conveys the cut strips to the rear, or the rest of the table to the front. Since the conveyor belt is automatically lowered when cutting, space is created for the descending top knife and the sheet metal sections conveyed to the rear for stacking are stacked on the lift equipped with the runway. The height of the lift can be adjusted automatically, whereby after reaching the permissible stack height, the lift is automatically lowered and the stack is extended.
  • the stacking device of the cross shear also consists of the height-adjustable conveyor belt with sheet metal supports that can be raised from it, as well as the downstream stacker with roller conveyor and height-adjustable stacking platform.
  • the stacking platform can be lifted from a carriage that can be lifted in the vertical direction there are a number of forks that collect the sheet metal sections behind the conveyor belt according to a minimum fall height.
  • the forks are automatically adjusted as the stack grows. If the stack height is reached, the forks are lowered between the rollers of the runway, so that the stack can then be extended either directly or on a pallet.
