Definitions

  • the device finds particular use in a planing machine for cutting paper, cardboard, foils or the like.
  • a stack to be cut which rests on a horizontally arranged table surface of a table of the cutting machine, advanced by means of a feed device under a press bar and a cutting blade.
  • the stack is clamped by means of the press beam and the knife is moved in a vertical plane in pulling section through the stack.
  • a stack also referred to as a benefit stack
  • Such a cutting device is for example in the DE 31 01 911 C2 described.
  • This shape of the stack after cutting may be due not only to the wedge shape of the knife, but also to the fact that the knife is held in a knife holder and this knife holder when lowering in the direction of the table surface shifts the upper sheet layers of the stack away from the cutting plane , thus contributes to the transfer of the stack in the shape with parallelogram-like cross-section.
  • a so-called benefit angle is used.
  • This is used manually and has a base plate for resting on the table and connected to the bottom plate and arranged at an acute angle to this ruler plate.
  • the angle that the ruler plate has with the table surface includes on this resting bottom plate substantially corresponds to the angle, which includes the parallelogram similar stack shifted on its side facing the utility angle with this.
  • the benefit angle when applied to the bottom of the stack prior to severing the stack, may support the stack in its parallell-like shape during cutting and thus transfer.
  • DE 44 22 194 C1 illustrates a benefit angle in which the bottom plate and the ruler plate at right angles to each other.
  • This benefit angle is used exclusively for aligning the stack, which is in a shape with parallelogram-like cross-section, in a cuboid shape.
  • the object of the invention is to provide a device of the type mentioned in such a way that a stack with a large height-width ratio is prevented in its transfer to a shape with parallelogram cross-section on tilting and a simple orientation of the stack of this shape in a cuboid shape is possible.
  • the device of the type mentioned is characterized by a comb-like support member with comb slots and with a flat support surface which is disposed at an acute angle to the horizontal and at an acute angle to the vertical, and by a sliding part with parallel projections, the free ends of which are arranged in a vertical plane which forms an alignment plane, wherein upon horizontal displacement of the sliding part perpendicular to the alignment plane for aligning the stack, the projections pass through the comb slots.
  • horizontal and vertical refer to the fact that in a cutting machine, in the context of the device according to the invention is used, the cutting plane of the cutting machine for receiving the stack to be cut is arranged horizontally and the cutting plane of Knife is arranged vertically. Accordingly, the leaves that make up the stack are arranged horizontally and lie against each other.
  • the device according to the invention has two functional components, wherein the one functional component is the comb-like support member, which serves to support the cut of the total stack separated stack due to the formation of the flat support surface, which in the cut in the shape parallelogram-like cross section is transferred.
  • the other functional component is the sliding part, which can be moved relative to the support part, wherein in moving the sliding part, the free ends of the projections of the sliding part, which form a vertical plane, increasingly pass through the comb slits and come into contact with the stack and with increasing displacement the sliding part is aligned in the direction of the stack of this on the alignment plane of the sliding part and thus converted into the cuboid shape.
  • the support member With respect to the support member retracted sliding part, the support member is applied in its lower portion to the entire stack, so that when cut the cut stack, which is in this case converted into the shape with parallelogram-like cross-section, is supported by the flat support surface of the support member. This prevents tilting of this stack, even if it has a large height-width ratio, in particular the center of gravity of the stack in the shape with parallelogram-like cross-section is outside the base of the stack. If, after the cut, the cutting blade has been raised again, by advancing the sliding part in the direction of the cutting plane, the stack can be aligned with the remaining stack left on the other side of the cutting plane, specifically with the vertical plane facing the cutting plane, thus converting the cut stack into a parallelepipedal shape becomes. Such an alignment of the stack can alternatively take place on a vertical ruler to be arranged on the side of the stack facing away from the device. Such is for example in the DE 31 01 911 C2 is described.
  • the sliding part can be moved manually or mechanically. With manual displacement of the sliding part, it is considered advantageous if this is provided on its side facing away from the alignment plane with a handle.
  • mechanically displaceable design of the sliding part adjusting means are provided for moving the sliding part in the direction of the cutting plane and away from it.
  • the acute angle included by the planar support surface of the comb-like support member relative to the vertical substantially corresponds to the wedge angle of the cutting blade of the planing machine or the wedge angle of a knife holder for the cutting blade of the planing machine.
  • the side of the cut stack facing the device is thus arranged essentially parallel to the flat support surface of the comb-like support part.
  • a parallelogram-like cross-section is understood to mean one which is not strictly parallelogram-shaped. This is to be seen against the background that when cutting the stack, acceleration forces act as the blade passes through the stack onto the blades, which are different. As a rule, therefore, there is no exact cross section representing a parallelogram.
  • the support member is designed when it is designed as a plate having the comb slots.
  • the support member and a bottom part which is designed in particular as a bottom plate, form a structural unit.
  • the bottom plate is arranged horizontally and the support member is arranged at an acute angle to the bottom plate.
  • the structural unit mentioned can be a constructive or else a functional structural unit.
  • the sliding part and a vertically arranged bearing plate form a structural unit.
  • the bearing plate is on the alignment plane of the sliding part opposite side of the projections connected to these.
  • unit may be a structural or functional unit.
  • the projections of the sliding part are formed in particular as vertically arranged, mutually parallel plates. This results in a structurally particularly simple design of the sliding part.
  • the sliding part preferably has a handle connected to the bearing plate.
  • the projections of the sliding part are in particular on the bottom plate.
  • the extent of the bearing plate and the support part viewed in the alignment plane and in the width extension of the comb slits, is the same, at least substantially the same. This results in a defined working width of the device due to the dimensions of the bearing plate and the support member, thus indirectly by sliding part and support member.
  • a receptacle with plate-shaped bottom and perpendicular to the bottom and mutually parallel side walls, for receiving the support member and the sliding part, in particular of the support member having assembly and the sliding part having assembly between the sidewalls.
  • the receptacle thus forms a spatial region of the device which interacts with the support part and sliding part and serves to receive the cut stack or a plurality of juxtaposed or even several stacks arranged next to one another and in front of one another. These multiple stacked stacks are created in multiple cuts. It Thus, it is not necessary to remove the cut pile or stacks immediately after a cut, but further cuts can be made before the stacks produced are removed. After each cut or after several cuts, the alignment of the stacks produced can be done by means of the device.
  • the extension of the bearing plate and the support member is particularly chosen so that it, in the alignment plane and in width extension of the comb slots, is slightly smaller than the distance between the two side walls. As a result, the bearing plate and the support member is guided in a direction perpendicular to the cutting plane through the two side walls of the recording.
  • the upper surface of the plate-shaped bottom forms a plane with a horizontal table surface of the cutting machine below the cutting blade of the cutting machine. Accordingly, by means of a feed device of the cutting machine, the material to be cut can be advanced to the plate-shaped bottom, which forms with its upper surface the plane with the horizontal table surface of the cutting machine.
  • the device consists in particular of plastic.
  • the principle in the Fig. 1 and 2 illustrated inventive device 1 comprises a support member 2 and a bottom part 3, which form a structural unit, further comprising a sliding part 4 and a bearing plate 5, which also form a structural unit.

  • the support member 2 is formed comb-like with comb slots 6 and it has the support member 2 has a flat support surface 7. This is arranged at an acute angle to the horizontal and at an acute angle to the vertical.
  • the sliding part 4 is provided with parallel projections 8, the free ends 9 are arranged in a vertical plane which forms an alignment plane 10. During horizontal displacement of the sliding part 4 perpendicular to the alignment plane 10, the projections 8 pass through the comb slots 6.
  • the support member 2 is formed as a plate having the comb slots 6.
  • the bottom part 3 is formed as a bottom plate.
  • the bottom part 3 is arranged horizontally and it is the support member 2 at an acute angle to the bottom part 3 is arranged.
  • the bearing plate 5 is connected to the aligning plane 10 of the sliding part 4 opposite side of the projections 8 with these.
  • the projections 8 are formed as vertically arranged, mutually parallel plates.
  • the sliding part 4 is provided on the side facing away from the alignment plane 10 with a handle 11 which is connected to the bearing plate 5.
  • the extension of the bearing plate 5 and the support part 2 is, in the alignment plane 10 and in widthwise extension of the comb slots 6 equal, at least substantially equal.
  • the device has a receptacle 12 with a plate-shaped bottom 13 and perpendicular to the bottom 13 and mutually parallel side walls 14, for receiving the two units, which have the support member 2 and the sliding part 4.
  • the two units are in this case added between the side walls 14.
  • the extension of the bearing plate 5 and support member 2, seen in the alignment plane 10 and in width extension of the comb slots 6, is slightly smaller than the distance between the two side walls 14.
  • the connected to the support part 2 bottom part 3 rests on the floor 13 and it is the Projections 8 on the bottom part 3.
  • the receptacle 12 may be made of plastic, or metal. When using metal, the advantage can be seen that the receptacle 12 may have a smaller wall thickness, in particular in the region of the bottom 13.
  • the device according to the invention finds use in connection with the in the Fig. 3 to 7 illustrated plan cutting machine 15.
  • This has a table 16 with horizontally arranged table surface 17.
  • the table 16 is used in the area of the table surface 17 of the recording of stacked Sheet material of paper, cardboard, foil and the like.
  • the stack or stacks are cut into partial stacks, which are also referred to as stack for the sake of simplicity.
  • the planing machine 15 is provided with a cutting blade 18, a knife holder 19, a pressing beam 20 and a feed saddle 21.
  • a feed saddle 21 By means of a feed saddle 21, a stack to be cut 22 is advanced under the cutting blade 18 and clamped by means of the press beam 20 between this and the table 16.
  • Adjacent to the pressing beam 20, the cutting blade 18 is arranged, which at the decline of the knife holder 19 and thus of the cutting blade 18 a partial stack - stack 23 - separates, so that a residual stack 24, which then forms the subsequently to be cut stack remains.

  • the wedge shape of the cutting blade 18 and knife holder 19 causes the separation of the stack 23 of this is moved in and thus, as the representation of Fig. 6 can be seen, is converted into a shape that has a parallelogram-like cross-section. In this figure, the cross section is shown exactly as a parallelogram.
  • the device 1 finds particular use in the case where by means of the plan cutting machine 15 stacks 25 are generated which have a large height-width ratio.
  • the height of the stack 23 is thus greater by a multiple than the extension of the stack in the feed direction X of the feed saddle 21. This is associated with the risk that the Stack 23 tilts, in particular because its center of gravity is outside the contact surface of the stack 23 with its base. In the figures, for reasons of better illustration, no large height-width ratio of the stack 23 is illustrated.
  • the table 16 is formed in two parts and has, based on the feed saddle 21, on the side facing away from the cutting plane 25 side arranged table part 27 which is lowered in parallel.

  • the stack 22 is advanced by means of the feed saddle 21, to beyond the cutting plane 25 out, in reality, the stack 22 is pushed over a much smaller distance than shown on the cutting plane 25 to the said large height-width To achieve ratio of the stack to be cut off. It is then, in the arrangement of the device 1 as shown in FIG Fig. 1 the device 1 is positioned on the stack to be cut 22 so that the sliding part 4 rests with its projections 8 on the stack 22. Then the cut takes place.
  • the press beam 20 is lowered onto the stack 22 and the cutting blade 18 is lowered, thus producing the stack 23 which is in the shape of a parallelogram-like cross section due to the wedge shape of the cutting blade 18 and knife holder 19.
