Definitions

  • the invention relates to a cutting machine for flat material, in particular a fabric cutting machine, with a support for the flat material, a carriage which is displaceably guided along the support by means of at least one running rail and which has a cantilever arm which extends over the support and can be pivoted relative to the latter about an at least approximately vertical first pivot axis carries, which has at least two arms which are connected to each other via a joint with a second pivot axis parallel to the first pivot axis and whose outer one carries a cutting device which is pivotable relative to the outer extension arm about a third pivot axis parallel to the first pivot axis and in operation with one foot rests on the edition.
  • Such a cutting machine is known from DE-OS 27 03 066; with it, the carriage guided on two rails is firmly connected to an upstanding column on which the first pivot axis for the boom is attached.
  • the trolley, column and boom are extremely stable because they are intended to hold the cutting device designed as a butt knife machine above the table-shaped support in such a way that the foot of the butt knife machine just touches the support.
  • This goal is also served by a spring-mounted suspension of the straight knife machine on the boom in a height-adjustable bearing.
  • the invention was based on the object of developing an inexpensive cutting machine of the type mentioned above, the inventor starting from the idea that the first thing that matters with such a cutting machine is always to keep the cutting element of the cutting device perpendicular to the support, in order to do so Processing a stack of flat material layers to avoid oblique cuts and thus cut pieces of different sizes.
  • "Vertical" is intended only to mean in a butt knife machine that the plane defined by the butt knife and the feed direction is perpendicular to the plane defined by the surface of the support, although such a construction is preferred in which the front cutting edge of the butt knife is always at least approximately runs perpendicular to the edition.
  • this object can be achieved in that the cutting device can be pivoted relative to the support about a tilting axis parallel to the support and is supported with its foot on the support.
  • the tilting axis can be provided somewhere between the support and the cutting device; for example, two could drive the car leading rails can be mounted on a support which is pivotable about the tilt axis relative to the support, or the outer extension arm could consist of two parts connected via the tilt axis.
  • a counterweight designed in the form of a cantilever can be attached to the tiltable area of the column, opposite the cantilever.
  • FIG. 1 shows a table top serving as a support 10, which is supported by a frame 12 which is only partially shown.
  • a running rail 14 formed by a square profile tube is fixedly attached, which extends in the longitudinal direction of the support 10 and on which a carriage 16 of a cutting machine is displaceably guided.
  • It has two support rollers 20, one behind the other, as shown in FIG. 1, provided with wheel flanges 18, of which FIG. 1 shows only the support roller facing the viewer and which roll on the top of the running rail 14, and at least one support roller 22 which is on the underside of the Track 14 rolls.
  • a column 24 is fixedly attached to the carriage 16, on which a boom designated as a whole by 26 is rotatably mounted by means of a first pivot bearing 28; the latter defines a first pivot axis 30 which, when the cutting machine is in operation, runs at least approximately perpendicular to the surface formed by the support 10.
  • the extension arm 26 extends over the support 10 and comprises an inner and an outer extension arm 32 and 34 as well as a second pivot bearing 36 with a pivot axis 40 running perpendicular to the support 10, via which the two extension arms are articulated to one another.
  • the cantilever arm 34 is provided with a third pivot bearing 44, the pivot axis of which also extends perpendicular to the support 10 and in which a conventional electric ram knife machine 48, as described in DE-OS 27 03 066, is suspended and rotatably mounted . It has a guide handle 50, a support 54 designed as a guide for the thrust knife 52 which oscillates in the vertical direction, and a footplate 56 fastened to the lower end of the latter, with which the cutting machine is supported on the support 10.
  • a rigid arm 60 is attached to the column 24, wherein “rigid” is only intended to mean that the arm 60 should not be pivotable about a vertical axis. It also extends over the support 10 and, in the preferred embodiment, can be adapted to the width of the support 10 due to its telescopic design. With the help of the boom 60, the carriage 16 can be operated by an operator standing on the right side of the support 10 according to FIG. drive back and forth along the support.
  • the carriage 16, the column 24 and the arm 26 can be tilted to a limited extent around the running rail 14, as will now be explained with reference to FIG. 2.
  • the idler rollers 20 have a ball-shaped tread 20a on one side, which forms two circular arcs in axial section, the center of curvature of which has been designated 20b and the radius of which has been designated R.
  • the support roller 22 is laterally offset from the center of curvature 20 b, which makes it possible to tilt the carriage 16 and the column 24 counterclockwise by a limited angle from the position shown in FIG. 1 despite the use of a rectangular square profile ( see the tilted position shown in broken lines in FIG. 2).
  • a preferably adjustable stop 64 is also attached to the column 24, which in particular can have the form of a screw with a lock nut and, after dismantling the push knife machine, is intended to prevent the boom 26 from moving in the direction to edition 10 tilts down. In the normal operating state, however, the stop 64 should be at a short distance from the support 10 or the frame 12. Another advantage of the stop 64 is that the boom 26 and the thrust knife machine 48 do not tip far down when the thrust knife machine once extends beyond the support 10.
  • the embodiment according to FIG. 3 differs only in the type of guidance of a carriage 16 'from the embodiment according to FIGS. 1 and 2. In the cutting machine according to FIG.
  • a running rail 14' with a circular cross section on a frame 12 'for a support 10'
  • the carriage has two support rollers 20 'with a circular arc-shaped running surface 20a', the curvature of which is adapted to the outer radius of the running rail 14 '.
  • the carriage 16 ' has at least one support roller 22' centrally below the support rollers 20 ', so that the carriage can tilt about the longitudinal central axis of the running rail 14'. It is particularly advantageous in this embodiment that the tilt axis 66 'is only very slightly below the surface of the support 10'.
  • an upper and a lower running rail 104 or 106 for a carriage 108 are mounted on a frame 102 carrying a support 100, which carriage has two carrying rollers 110 for the running rail 104 and two supporting rollers 112 for the running rail 106.
  • a rack 116 is fastened to the frame 102 below the running rail 104 and engages with a pinion 120 which can be driven by an electric gear motor 118.
  • the geared motor 118 can be switched on and off via an electrical switch 122 and switched in its direction of rotation, this switch being fitted above the push knife machine 48.
  • FIG. 4 shows a possibility for relieving the weight of the support 54: on the side of the column 130 opposite the extension 26, a support arm 200 is attached to the latter, along which a counterweight 202 can be displaced.
  • a locking screw 204 serves to fix the counterweight 202 in a position in which the base plate 56 only rests on the support 100 with a slight force.
  • the support arm 200 can be kept relatively short.
  • first pivot bearing e.g. the pivot bearing 28 in the embodiment according to FIG. 1 could also be provided between the carriage and the column, although such an embodiment is not preferred because it would then no longer be possible to use the rigid arm 60 to move the carriage along the support move.
  • the tilting bearing 132 could also be somewhat higher or the column 130 could extend down to below the support 100, so that the column would consist of two parts pivotally connected to one another via the tilting bearing.
  • All embodiments are particularly advantageous in which the approximately horizontally extending tilt axis about which the boom carrying the cutting device can be pivoted is approximately at the level of the support for the flat material or slightly above or below it. Manufacturing tolerances with regard to the height of the tilt axis then play the least role.
  • Are there upper and lower guides for the carriage e.g. If the elements 20 and 22 in the embodiment according to FIGS. 1 and 2 or the elements 104 and 106 or 110 and 112 in the embodiment according to FIG. 4 are provided, it is advisable to arrange the tilting axis approximately at the level of the upper carriage guide .
  • the carriage carrying the boom can be tilted together with the boom, the carriage can be made much simpler and lighter, and it no longer has to be held on its guides as stably and precisely as is the case with the known cutting machines of the type in question here is.
