Definitions

  • the invention relates to a device for cutting stacked, sheet-like material, with a table surface, which has a working area, above which there is a cutting knife and a press beam, an input field for receiving the material to be cut and an output field for receiving the cut material , with a feed device for the material to be cut, which has teeth in its foremost position in the grooves of the press beam, and with a side stop for aligning the material to be cut by means of a pressure slide movable in the area of the working area in the direction of the cutting line.
  • Such a device is known from EP 0 242 763 A2.
  • an automatically movable pressure slide is provided for pressing the material to be cut against the side stop, the effective width of the feed device being smaller than the distance between the side stop and pressure slide. Since the effective width of the feed device is shortened compared to the normal machine width, the pressure slide can remain in place without colliding with the feed device. The working distances of the pressure slide and its operating time are correspondingly short. Since it is actuated automatically, the time interval until the subsequent cut can also be kept small. Overall, this configuration results in a transverse alignment with a minimum of time, and it is also not difficult to carry out the alignment before each cut. It is also known from this document to arrange the pressure slide above the working area behind the pressure beam effective plane. In addition, it is proposed that the pressure slide can be moved first under this and then in the pressure direction when the pressure beam is raised, so that the pressure slide can be brought as close as possible to the cutting line.
  • a disadvantage of the known device that the feed device must be converted or replaced to adapt to different widths of the material to be cut, which is due to the required smaller effective width of the feed device compared to the distance between the side stop and pressure slide.
  • the device can therefore only be used economically if constant batch formats have to be cut in large numbers.
  • the feed device extends essentially over the entire width of the table surface and the pressure slide is only effective in the area of the working field formed between the cutting plane and the foremost position of the feed device.
  • the inventive design of the device initially enables any stack formats to be cut without changing or replacing the feed device.
  • the device can be designed universally in the area of the feed device and can have, for example, the usual spindle-operated feed saddles known from face cutting machines.
  • the pressure slide is only effective in the area of the work area that cannot be reached by the feed device, which means that the pressure slide is relatively narrow.
  • the pressure slide in the immediate vicinity of the cutting plane can be of any narrow use, be it use that extends across the entire width of the table or use in the form of block strips exactly aligned with the side stop.
  • the pressure slide should be able to move essentially over the entire width of the table, at least up to the vicinity of the side stop.
  • a special embodiment of the invention provides that the pressure slide is connected to a push rod arranged above the table surface and parallel to the cutting plane in the direction of the cutting line.
  • the push rod can be formed by the piston rod of an actuating cylinder, in particular a pneumatically actuated actuating cylinder, which is arranged outside the working area.
  • the positioning cylinder is advantageously attached to the side of the table or to a portal frame of the device which receives the knife and the press beam.
  • the push rod is also the possibility of designing the push rod as a toothed rack with which a toothed wheel of a power means arranged outside the working field, for example an electric servomotor, interacts.
  • the pressure slide can, for example, be arranged parallel to the side stop and rigidly connected to the end of the push rod facing the side stop. Since the pressure slide, in order to fulfill its function, stands above the stack to be cut, this rigid arrangement of the pressure slide means that it has to be moved out of its effective area before the pressure beam is lowered.
  • the push rod is arranged directly adjacent to the table surface and the pressure slide is pivotally connected about a horizontal axis to the end of the push rod facing the side stop.
  • the pressure slide removed in a simple manner from the effective area of the press beam by pivoting it under the upper boundary surface after the stack to be cut has been aligned, with which it can remain in the immediate vicinity of the stack to be cut.
  • an adjusting means is provided for pivoting the pressure slide between the vertical working position and in particular an essentially horizontal rest position.
  • the adjusting means should be designed as a rod which can be actuated by means of a force and which acts on the pressure slide at a distance from the pivot axis thereof. In order to ensure a defined position of the pressure slide in its working position, it is considered advantageous if it is supported in this position via a bearing surface on a corresponding bearing surface of the push rod.
  • the height of the pressure slide should be based on the maximum height of the material to be cut that can be processed in the device. In this sense it is provided that the pressure slide extends in its working position essentially from the table surface to slightly below the raised press beam.
  • the push rod is advantageously arranged between the cutting plane and a pull rod for the press beam. Despite the small space between the cutting plane, that is, the cutting knife and the feed device and the mechanism for actuating the pressure beam, there is therefore sufficient space for the defined movement of the pressure slide.
  • the invention is illustrated, for example, on the basis of a basic embodiment with two partial variants, without being restricted to this embodiment.
  • a table 1 with a table surface 2 is shown for the face cutting machine, which is divided into an input field 2a, a working field 2b and an output field 2c.
  • the input field 2a serves to receive the material to be cut, above the working field 2b there is a press beam 3 received by a portal frame of the cutting machine (not shown) and a cutting knife 4 only shown in broken lines.
  • Reference number 4a is the cutting plane of the cutting knife 4 clarifies.
  • the output field 2c serves to receive the cut material.
  • a feed device in the form of a feed saddle 5 is mounted so that it can be moved in the feed direction C.
  • the width of the feed saddle 5 is only insignificantly smaller than the narrow edges 6 of the table 1 which define the width of the table 1.
  • the feed saddle On the side facing the press beam, the feed saddle is comb-shaped in plan view and thus has a large number of equally spaced teeth 7 (see also Figure 2).
  • the press beam 3 is provided on its side facing the feed saddle 5 with grooves 8 in which the teeth 7 can engage.
  • the maximum advanced position of the feed saddle 5 is shown, that is, the closest position that the feed saddle 5 can assume with respect to the cutting plane 4a. In this, the teeth 7 of the feed saddle 5 fully engage in the grooves 8 of the press beam 3, so that a space remains below the groove-free area 3a of the press beam 3.
  • a pressure slide which is movable in the direction of the cutting line — likewise illustrated by reference number 4 a in the plan view according to the representation of FIGS. 1 and 2 — is movable against the material 9 to be cut 10 provided.
  • the pressure slide 10 is connected to a push rod 11 which is arranged above the table surface 2 and can also be moved parallel to the cutting plane 4a in the direction of the cutting line.
  • the push rod is designed as a toothed rack, with which a toothed wheel (not shown in detail) of a servomotor 12 arranged outside the working field 2b interacts. This and thus also the push rod 11 are arranged between one of the two tie rods 13 for pulling down the press beam 3 and the cutting plane 4a.
  • the push rod 11 is rigidly connected to the pressure slide 10 in the region of the center thereof.
  • FIGS. 2 and 3 illustrate the conditions for the last cut of five block strips 9a to 9e which takes place in the immediate vicinity of the cutting knife 4.
  • the pressure slide 10 is moved out of the working area 2b, the block strips are advanced to the cutting plane 4a by means of the feed saddle 5.
  • the push rod 11 is extended with the pressure slide 10 until it lies against the outside of the block strip 9a and the good 9 to be cut presses against the side ruler 14 and aligns it laterally. This position is also illustrated in the front view of Figure 3.
  • FIG. 6 illustrates an alternative arrangement of the expression slide 10 on the push rod 11.
  • the representation of the actuating means for the press beam 3 has been omitted.
  • the push rod 11 is arranged there directly adjacent to the table surface 2 and the pressure slide 10 can be pivoted about a horizontal axis 15 connected to the end of the push rod 11 facing the side stop 14.
  • a further rod 16 is guided, with which the pressure slide can be pivoted counterclockwise by a maximum of 90 °, thus into a horizontal position.
  • the rod 16 acts on a shoulder 17 of the pressure slide 10 at a distance from the pivot axis 15.
