Definitions

  • the invention relates to a device for cutting stacked sheet-like material made of paper or film material, with a table surface, a working area, above which there is a cutting knife and a press beam, behind an input field for receiving the material to be cut and an output field in front of it Includes recording of the cut good, with a side stop for aligning the good to be cut and with a feed device for the good to be cut.
  • Such a cutting device is known from EP-A-56 874.
  • the person skilled in the art knows that the cuts are made more precisely the better the stacked material to be cut is oriented in the transverse direction, that is to say at the side stop, and in the longitudinal direction, that is to say at the feed device.
  • This alignment is usually done by an operator by hand performed with the help of an angular pressure element.
  • this is tedious and time consuming, especially if you want to re-align before each cut.
  • DE-A-31 11 256 describes a device for the color division of plate-shaped materials, in which a sawing system has a table surface with a work area, on the front edge of which a press beam is provided, which presses the plate-shaped workpieces onto the table, while a circular saw blade along a cutting line is used to cut the plate into strips or pieces. Behind the work area there is an entrance area for receiving the goods to be cut and in front of it an exit area for receiving the cut goods. A side stop for aligning the good to be cut, a feed device for the good to be cut and a pressure slide movable in the direction of the cutting line for pressing the good to be cut against the side stop are provided.
  • the feed device is adjustable so that it can grip only one of a series of plate strips arranged in parallel on the input field and advance it perpendicular to the cutting line.
  • FR-A-23 36 217 describes a conveyor device for a mechanical saw, in which strip-shaped plates are advanced in the direction of a movable saw blade. The stack of plates must already be aligned be. A side stop is not provided.
  • the device has a slide which is divided into two in the transverse direction and has two slide elements, the effective width of each slide element being able to be set individually by raising or lowering slide fingers which are each assigned to a plate strip. However, the overall width of the slide should be kept constant.
  • US-A-2 589 033 describes a paper cutting machine using a frame-shaped punch knife.
  • the paper stack to be cut can be aligned in its intended place with the aid of stops or holders.
  • Each holder has a resilient stop surface which can be moved slightly outwards when the punch knife is lowered into the paper stack and can be inclined outwards when the punch knife is lowered.
  • FR-A-11 50 136 shows machine shears in which a closable opening is provided in the exit field.
  • the opening can be opened to receive pieces of waste during an intermediate cut. Simultaneously with the opening of the opening by lowering a flap, devices are moved out of the plane of the exit field which prevent the paper waste from reaching the exit field.
  • the invention has for its object to provide a cutting device of the type described above with improved alignment options.
  • This object is achieved in that a pressure slide that is automatically movable in the direction of the cutting line is provided for pressing the material to be cut against the side stop and that the effective width of the feed device is smaller than the distance between the side stop and pressure slide.
  • the pressure slide can remain approximately 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 up to the subsequent cut can also be kept small. Overall, there is a transverse alignment with a minimum of time. It is therefore not difficult to carry out this alignment before each cut.
  • Interchangeable feed devices of different widths can be provided to adapt to different widths of the material to be cut. However, it is much cheaper if the feed device is divided into individual segments in the direction of the cutting line, the feed function of which can be rendered ineffective at least over part of the cutting knife width. By making the feed function effective for a more or less large number of segments, the effective width of the feed device can be adapted to the particular circumstances.
  • the segments can be moved from an operating position in which they take the material to be cut into an ineffective position.
  • the segments In the inactive position, the segments are lifted off the table surface of the cutting device and therefore do not collide with the pressure slide.
  • the segments can be pivoted up and back about a horizontal axis located behind them in the working position.
  • there are also other ways of rendering the feed function ineffective for example by uncoupling the ineffective segments from the feed drive.
  • the segments In the case of a cutting device in which the feed device has teeth which engage in the foremost position in grooves of the press beam, it is recommended that the segments have a pitch corresponding to the tooth pitch.
  • the segments can then be designed identically to one another.
  • the respective effective width range of the feed device interacts with the press beam in the same way as was previously the case for the entire feed device.
  • the pressure slide is expediently located above the working area behind the pressure beam effective level. In this position, it is located close to the cutting line so that the alignment takes place in the cutting area.
  • the pressure slide can be moved first under the pressure beam and then in the pressure direction when the pressure beam is raised. In this way, the pressure slide can be brought even closer to the cutting line.
  • a feed path for the material to be cut which runs transverse to the feed direction. The material can therefore be fed in without colliding with the pressure slide.
  • the input field can be formed by a transport plate which can be moved transversely to the feed direction.
  • the stacked goods to be cut can already be transported on this transport plate with a certain pre-alignment. It can also be brought up to the side stop with the help of the transport plate, resulting in a certain basic orientation.
  • the feeding of the material in the transverse direction and the reduced effective width of the feed device have the further advantage that not all of the material to be cut, which is located on the input field, has to be cut, but that - if this material is present, for example, in block strips arranged next to one another - One or a few block strips can be advanced and cut.
  • a holding-down device extending in the feed direction is expediently provided behind the pressure slide. This then holds the adjacent block strips in place when the block strips are advanced. With this hold-down device there is also no risk of a collision with the feed device.
  • the feed device can be lifted overall and can be returned to the rear in the raised state.
  • new goods can already be brought to the side stop via the feed path, while the feed device is returned to the starting position, because the feed device can be moved over the new goods.
  • the side stop can expediently be raised for the passage of the transport plate. This makes it possible to move the transport plate under the side stop as far as is necessary for the delivery of the entire stacked goods.
  • a filler of the side stop in the area of the cutter bar a filler of the side stop can be moved downward with the cutter bar and can be lowered to below the table surface during the feed movement.
  • the filler of the side stop is available Available if the goods are aligned transversely using the pressure slide. Since the filler piece sinks below the table surface, the stacks of the cut goods are not obstructed when they are removed from the work area to the front. Especially with smaller labels u. The like. The stack shape is preserved better than before.
  • a ruler running in the direction of the cutting line and arranged on the starting field can be provided, which has a limited stroke counter to the feed direction in order to press the material to be cut against the feed device.
  • the ruler Since the ruler is on the starting area, it can be placed at a distance from the working area. It is therefore possible to carry out the longitudinal alignment after the feed device has pushed the material to be cut into the position intended for the cut. The longitudinal alignment, like the transverse alignment, can therefore be carried out immediately before each cut.
  • the arrangement of the ruler on the starting field can also be used for further advantageous purposes.
  • the ruler can be tilted about a lower horizontal axis to support the stack of the cut material during cutting and then to straighten it up again. Relatively high stacks of small labels or the like can therefore be handled safely.
  • Hold-down elements can also be attached to the ruler, which lie resiliently on the material to be cut. This is of advantage, for example, if the sheet-like material is somewhat brittle and therefore tends to jump off when cutting.
  • a transverse channel leading to a further processing point on the exit field is recommended, which is formed by a first ruler mounted on the exit field and a second ruler behind it, which after opening the gap in his working position is feasible, and an ejector that is movable along the transverse channel.
  • the stack or stacks in particular also those with a relatively small sheet size, can be passed on, for example, to a punching device or an automatic bundling machine.
  • the second ruler can be provided with a squeegee and controlled so that it wipes along the knife bar when it moves upwards. This removes paper residues.
  • the squeegee be slid in the working position towards the inclined surface of the cutter bar. This sliding movement allows stripping to take place over the entire sloping surface.
  • the segments of the feed device and / or the side stop and / or the pressure slide have vertically movable sliding fingers seated on the table surface. This ensures that, despite the various movements of the parts mentioned, there is always contact with the table surface, so that the goods are gripped down to the bottom sheet of the stack.
  • the use of the cutting device as a second cutting device of a system in which a first cutting device is designed for the production of block strips by parallel cuts is particularly advantageous, in the second cutting device only a partial number of the effective segments of a number of block strips arranged next to one another in the direction of the cutting line the feed device can be taken along.
  • the use of two cutting devices, each of which is designed for one function, namely longitudinal cutting for producing the block strips, and cross cutting of these block strips, results in very efficient production.
  • the second cutting device works practically fully automatically and therefore very quickly.
  • the transverse cutting of the block strips can thus take place in approximately the same time as the manual longitudinal cutting of these block strips in the first cutting device. This does not exclude that the block strips are also supplied to the second cutting device by a plurality of first cutting devices, or conversely the block strips of a first cutting device are supplied to more than one second cutting device.
  • FIG. 1 shows a first cutting device 1 in the form of a face cutting machine with an indicated cutting line 2.
  • block strips 4 are separated from stacks 3 of large-area sheet material, the stacks 3 being aligned in the usual way on a side stop 5 and being advanced step by step by a feed device 6.
  • the loaded transport plate 8 arrives at a transfer station 11.
  • This has a buffer shelf 12 with a plurality of levels 13 arranged one above the other (FIG. 5), which can each be raised to the working height with the aid of a lifting device 14.
  • Each floor has at least two guide rails 15 and 16 and, if appropriate, further support means, such as rollers.
  • the transfer station 11 is formed by the level 13 located at the working height.
  • the transfer station 11 connects directly to a second cutting device 17, the cutting line 18 of which is again indicated by dash-dotted lines in FIG. 1.
  • This cutting device has a table surface 19, which consists of an input field 20, a working field 21 and an output field 22.
  • the input field 20, which roughly comprises the area B1 is formed by a transport plate 8 in each case.
  • the work area 21, which comprises approximately the area B2, is located below a cutting knife (cutter bar) 23, a press bar 24 (FIG. 7) and a pressure slide 25.
  • the exit area 22, which is located above can extend the area B3, serves to receive the finished cut stacks.
  • On one side of the exit field 22 there is an automatic bundling machine 27 for packaging the finished stacks and on the other hand an automatic punching machine 28 for further processing of the stacks. These machines can be used optionally.
  • the cutting device 17 has a feed device 29 which is composed of individual segments 30. These segments 30 each sit on a lever arm 31 which is pivotable about a rear axis 32. They can therefore be shifted from an effective position (fully extended in Fig. 2), in which they sit on the table surface 19, to an ineffective position (dash-dotted lines in Fig. 2), in which they are out of engagement with the table surface and the one located thereon Are stacked.
  • the pivoting is done by hand, but can also be carried out automatically by suitable drive means, for example servomotors.
  • Each segment 30 can have a sliding finger 33 which is guided vertically in the segment and is in contact with the table surface 19 due to its weight.

  • the cutting device 17 is provided with a side stop 51, to which a proximity initiator 52 is assigned.
