Definitions

  • the invention relates to a device for cutting paper, cardboard or the like.
  • the material to be cut is advanced on a table by a feed unit by a desired amount, and an intermediate cut is provided in the edge cuts, as well as following one or more main cutting processes are.
  • the width of the paper strips resulting from paper waste is kept as small as possible when inserting edge cuts and intermediate cuts.
  • paper strips are produced when inserting edge or intermediate cuts, the width of which is approximately 1.5 to 2 mm.
  • the paper strips created by the edge cuts can be removed by machine, the paper strips created by the intermediate cuts must be removed by hand. This usually happens after the complete separation of the collecting sheet into the individual partial sheets with the paper waste located between the partial sheets. The partial sheets have to be moved apart, the paper waste has to be removed and then the partial sheets have to be put together again. On the one hand, this is very cumbersome, on the other hand, it cannot be prevented that the partial sheets move against one another when they are moved apart and reassembled, which complicates the subsequent workflow.
  • a device for cutting paper, cardboard or the like in which the material to be cut is shifted by a desired amount on a table by a feed unit, and in the edge cuts, and subsequently an intermediate cut is provided for one or more cutting operations.
  • the table consists of a front part that receives the cut material and a rear part for receiving the material to be cut. So that the paper waste from the edge cuts no longer has to be removed manually, the device in the feed direction of the material to be cut has a flap designed as a paper support behind the cutting knife, which can be lowered downwards, creating a gap in the table through which the Paper waste can be conveyed down from the cutting area.
  • a lock arranged in the front part of the table on the side facing the gap is additionally folded up, as a result of which paper waste thrown against the lock bounces off the lock during the cutting process and be promoted through the gap.
  • a device for separating rolling stock in which the rolling stock is moved along a roller table consisting of several sections. A gap is formed between two sections of the roller table to remove the top ends of the rolling stock, and the separation process then takes place. The severed, heavy top ends fall through the gap, after the top ends have been removed, the sections are moved towards each other again, thus closing the gap.
  • the object of the invention is to provide a device of the type mentioned, in which, in addition to the main cutting processes, edge and intermediate cuts can also be carried out, but in which manual work can be omitted following these cuts or cutting processes.
  • the table according to the invention By dividing the table according to the invention into a front table and a rear table and the arrangement of a ruler, which is in its rest position below the front table and which can be moved into a working position in which it rests on the rear edge of the front table over the entire length of the separating surface and perpendicular to its paper support, it is ensured that both the paper waste resulting from the edge cuts and the intermediate cuts can be removed directly through the gap formed between the front and rear table without manual interference.
  • the arrangement of the ruler in its working position prevents brittle material from being thrown by the cutting knife onto the front table, regardless of whether it is an edge or intermediate cut.
  • the ruler enables the rear edge of a stack of cut material that was cut last to be pushed completely onto the front table when it is moved into the working position, and thus no material to be cut is pinched when the gap is subsequently closed.
  • the worker can also straighten the cut material stack, which is shifted due to the design of the knife, again with the aid of a utility angle, this straightening process also being able to be carried out automatically.
  • the possibility of being able to raise the end of the surface of the support of the front table facing the rear table relative to the surface of the rear table serves to detach the last cut part stack or parts from the cutting bar, on which, depending on the material, the condition of the material to be cut, the knife setting with respect to the cutting bar at the bottom dead center of the cutting cycle and the sharpness of the knife edge with the bottom bends.
  • control means are provided which control the device in such a way that the front table or support and rear table are pushed apart in time before the edge or intermediate cut. It is furthermore advantageous if the thickness of the gap which results when the front table or support and back table are pushed apart is a multiple of the width of the paper strips resulting from the edge or intermediate cut. This ensures that the paper strips can fall down unhindered through the gap.
  • the front table or the support can be displaced from the rear table perpendicular to the cutting plane.
  • the shift can be accomplished mechanically, hydraulically or pneumatically.
  • Control means are expediently provided which control the device in such a way that the displacement of the front table or the support is adapted to the sequence of the cutting program. In the ideal case, the device works fully automatically, so that the operating personnel do not have to carry out any additional operations and thus largely perform monitoring functions.
  • a container with a baffle located between the container and the gap for collecting the paper waste is arranged in the area of the separating surface from the front table or support to the rear table.
  • the guide plate should have a foldable part arranged in the region of the front edge of the rear table for aligning the material to be cut lying on the rear table. Alignment of the material to be cut is expedient because the material can be pulled more or less away from the front surface of the feed unit determining the format by the preceding pressing and cutting process - in particular in the area of the press beam - according to its material properties.
  • the lower arches of the material to be cut would lie against the front surface of the feed unit during the movement of the feed unit, but the upper arches would be spaced from the front surface. This would result in the creation of non-dimensional labels the next time the cut was made.
  • the arrangement of a foldable part in the region of the front edge of the rear table ensures that the material to be cut is pressed against the feed unit over its entire front surface during the folding process. It is advantageous if the folding process is tapped several times in quick succession in order to loosen up and align the individual layers of material, particularly in the case of material with a rough surface.
  • the alignment process should take place after the front table or the support and the rear table have been pushed apart and the ruler has moved into the working position and the paper strips obtained during edge trimming or intermediate cutting have been conveyed into the gap by a forward movement of the feed unit.
  • the control of the alignment process should also take place automatically in accordance with the control of the cutting processes.
  • the device according to the invention consists of a displaceable front table 1 and a non-displaceable rear table 2.
  • the rear table 2 receives a paper stack 3 to be cut.
  • the knife holder 7 comes into contact with the press bar 5 grips the knife 4 and thus ensures exact guidance during the cut.
  • a paper stripping device 8 is arranged in the area of the front of the knife, which stripes the paper strips stuck to the knife as a result of the static charge.
  • the stripping device 8 is expediently designed as a felt or broom which, due to the relative movement of the knife 4 returning after the cutting process to the stripping device 8, strips the paper strips which may be hanging on the knife 4.
  • a ruler 9 is arranged under the front table 1 in the area of the separating surface between the front table 1 and the rear table 2, this ruler 9 opening the gap 10 from the rest position shown in dashed lines according to FIG. 1 with the gap closed and into a working position shown in solid lines in FIG. 1 is movable, in which it rests over the entire length of the separating surface between the two tables 1, 2 on the rear edge 11 of the front table 1 and is perpendicular to its paper support surface 12.
  • the ruler 9 is pivoted by mechanical aids, not shown, due to the movement of the front table 1 to open the gap 10.
  • a guide plate 14 is arranged on the front edge 13 of the rear table 2 over the entire length of the separating surface between the two tables 1 and 2. Via this guide plate 14, paper waste falling through the gap 10 can fall directly into a waste container 15 during the edge or intermediate cut to be described.
  • This container 15 is expediently arranged for collecting the paper waste in the area of the separating surface from the front table 1 to the rear table 2.
  • the container 15 has a suction device 16.
  • this suction device can also by a transport device, for. B. a conveyor belt or a screw conveyor can be replaced.
  • the corresponding devices can be controlled via a clock which only switches on when the gap 10 between the front table 1 and the rear table 2 is open.
  • the advantage of this control is to be seen in the fact that people working on the device are not unnecessarily disturbed by the noise generated, for example, by suction or by drafts.
  • a paper stack 3 to be cut for example in the form of collecting sheets, is cut, it is necessary to trim the edges of the paper stack 3. This is shown for example in Fig. 1.
  • the paper stack 3, which is received by the rear table 2, is shifted by a feed device, not shown, by the amount of the edge strip 17 to be cut on the rear table 2.
  • the front table 1 is moved at the same time, the gap 10 is open in this position, and the ruler 9 is also in the solid position shown in FIGS. 1 and 2.
  • the pressure beam 5 is pressed down onto the paper stack 3 to be cut, then the knife 4 separates the edge strip 17 from the paper stack 3 when the edge strip 17 is pressed, the cutting edge 18 of the knife 4 touches the cutting bar 19 arranged in the rear table 2 during the cutting process, the vertical ruler 9 prevents the cut material from becoming brittle during cutting by the knife on the paper support surface 12 of the front derdisch is thrown.
  • the cut off edge strip 17 can only fall through the gap 10 via the guide plate 14 into the waste container 15. Should paper strips 17 stick to the knife 4, these are, as already described, removed from the knife 4 by the paper stripping device 8.
  • the cutting bar 19 is not located directly on the front edge 13 of the rear table 2, but is arranged parallel to the front edge 13, which is necessary due to the forces occurring during cutting.
  • the result of this is that the edge strip 17 formed during cutting can get caught on the front edge 13 of the rear table 2 and thus does not get into the waste container 15. 2, therefore, after the edge strip 17 has been separated off, an intermediate feed of the paper stack 3 to be cut is inserted. This takes place as follows: after the edge strip 17 has been separated in accordance with FIG. Fig. 1, the knife 14 and the press beam 5 is transferred to the rest position, not shown.
  • the cutting plane of the knife 4 corresponds to the dash-dotted line in accordance with. Fig. 2.
  • the paper stack 3 to be cut is in a position in which its cutting plane coincides with the dash-dotted line.
  • an intermediate advance of the paper stack to be cut 3 carried out.
  • the paper stack 3 to be cut assumes the position shown in FIG. 2, in which it would have pushed an edge strip 17 possibly remaining in the area of the cutting zone over the front edge 13 of the rear table 3.
  • the other edges of the paper stack 3 to be cut are trimmed.
  • the stack 3 must be rotated into the corresponding position by the operating personnel. This is facilitated by an air cushion located between the paper stack 3 and the front table 1, which is generated by air nozzles (not shown) located in the front table 1, which can also be arranged in the rear table 2.
  • FIG. 3 The further cutting course with the corresponding intermediate cuts can best be seen from FIG. 3.
  • the front table 1 is moved in the direction of the rear table 2. It swivels the ruler 9 from the vertically illustrated working position into its rest position below the front table 1 until finally the rear edge 11 of the front table 1 abuts the rear table 2.
  • the gap 10 previously formed between the front table 1 and the rear table 2 is thus closed.
  • the feed device moves the paper stack 3 to be cut up to the width to be cut in the direction of the front table 1.
  • a customary cutting process then takes place, as described in the explanations for FIG. 1 when the edge strip 17 is cut off, a first cut paper stack 20 being produced.
  • the bottom sheet of the paper stack 20 is due to the described arrangement of the cutting plane not only on the front table 1, but slightly covers the surface 6 of the back table 2. Due to the wedge-shaped shape of the knife, the individual sheets of the cut paper stack 20 are after the end of Separation process in such a way that the paper stack 20 has a parallelogram-shaped cross section as seen in the cutting plane.
  • the front table 1 is moved from the rear table 2.
  • the shift can be accomplished mechanically, hydraulically or pneumatically.
  • the ruler 9 is transferred from the rest position to the working position.
  • the ruler 9 assumes a position in the working position in which it rests on the rear edge 11 of the front table 1 and is perpendicular to the paper support surface 12.
  • the ruler 9 completely pushes the cut stack 20 above the front table 1 onto the front table 1. It is therefore not possible for the cut stack 20 to close in the further workflow to be described Gap 10 is pinched.
  • the ruler 9 remains in the vertical position. There it also serves as a contact surface for correcting the stack 20 in the form of a parallelogram. For example, by bringing the utility angle 21 towards the stack 20, it is possible to align it with the ruler located in the vertical position.
  • the paper stack 3 to be cut is advanced by the amount of the paper strip to be cut off during the intermediate cut.
  • This is followed by the workflow already described when separating the edge strip 17.
