Definitions

  • the invention refers to a procedure for cutting pieces of material from a band of material, as is stated in claim 1 of the patent.
  • the cutting line of the pattern it is necessary for the cutting line of the pattern to be cut to be established as an uninterrupted line, free of crosses, and that this line be explored by a tracing device, to be able to cut to order automatically and continuously, by means of the cutting tool, the different pieces of cloth, according to the explored cutting line.
  • the cutting head on the cutting tool itself is a costly mechanism to manufacture, which requires a tool carrier which is housed and works with an up-down movement for housing the blade, a foirst drive for the generating of the up and down movement and a second drive for the rotation of the tool carrier, as well as a third drive for the raising of the complete cutting head during its movement along the X and Y direction regarding the cutting table, as well as gears for the transmission of all of these movements. See publication DE 26 14 347.
  • the mission of this invention is to remedy this problem by using a new drive system for the cutting part and thus create a new pro- , cedure for automatically cutting pieces of material to order from a band of material, that is to say, to establish considerably simpler procedures than those which have been used to date.
  • the cutting movement frequency is much greater than in known systems.
  • the height of the fibers on the brush surface can thus be considerably reduced regarding the presently-known systems, which provides for considerable savings.
  • the moveable carriers coordinated with the area for cutting to order are controlable by means of a data-control processor NC, in such a way - in the X and Y direction - that the cutting head can reach any designated point on thersurface of the band of material.
  • the controlling signal for the direct current motors that move the carriers are generated in the so-called cutting line generators, thus making the directions of the movements and the accelerations and speeds controllable within ample limits.
  • NC control such as: fabric, paper, cardboard, plastic and similar materials, material in the shape of bands in individual layers or also in multiple layers for the purpose of which the material to be cut can be processed from a roll or as a flat sheet.
  • FIG. 1 a machine for automatically cutting to order, for example with NC controls, which is defined along general lines with reference number 20, is represented.
  • a material (24) to be cut is on the cutting surface (26), also defined as the cutting table.
  • the cutting surface is comprised of a type of brush surface (28) ( Figures 4 and 5) of synthetic fibers, approximately 0.5 mm thick and 5 mm in length, which is air-permeable, which covers the entire cutting surface and upon which the vacuum acts, which is generated by means of a generator (40)( Figure 2).
  • a carrier (49) has been designed, which is fundamentally moveable in the X direction and a carrier (62), moveable in the Y direction.
  • the X carrier (49) slides along rails (64), which are arranged in parallel to one another in the cutting area (26), while carrier Y's movement is crosswise and that of carrier X is lengthwise. Given that the movement in both directions takes place according to the same principle, only the movement in direction X is described here.
  • the drive of the carrier in direction x is comprised of a direct current motor (66), located at the front part of the cutting area, a tachometer (68) and a position regulator (70), which is controlled by a position servoregulator, not shown here.
  • a direct current motor 66
  • a tachometer 68
  • a position regulator 70
  • the motor 66
  • the axle 76
  • a nonstop conveyor belt is guided, which supports the brush surface (28).
  • toothed pulleys At the free ends of the axle, there are toothed pulleys (78,80), by means of which the toothed belts (82,84) are guided, nonstop, which are kept taut by means of the toothed pulleys (86,88).
  • the X carrier (49) is screwed to the toothed pulleys (84), through which it is synchronized in movement with the belts (82,84).
  • carrier X there is a direct current motor (90), a tachometer (92), a position regulator (94), a gear (96,98) with drive pulleys (100), a toothed belt (102) and a tensing roller (104), which serve to drive carrier Y (62).
  • the movements in direction Y are controlled in the same way that it is done in direction X, by means of a coordinated regulation of the position, for which purpose the habilitation signals for the X and Y regulation coils, in addition to the cutting tool (106) for the movement, rotation, around axle Z located perpendicularly to the cutting surface (26) are generated in a control apparatus (18).
  • the cutting tool (106) has one edge (108) which is oriented exactly in the direction of axle Z, perpendicular to the cutting s face (26), around which the cutting-tool (106) rotates.
  • the length of the edge of the blade (108) only has to be longer by a short safety distance, - reference number 112,- measuring approximately 2 - 3 mm longer than the pile (24a) of material to be cut. In this way, it is assured that, along the full length, the blade does not penetrate the cutting surface (26).
  • a cutting tool (116) designed in a different way, principally, when few layers of cloth are to be cut.
  • This cutting tool (116) is shown in Figure 5 and has one edge (118), which is located under a slight cutting angle ( ⁇ ) regarding the cutting surface (26). This angle is smaller than the right angle, which is formed by the edge (108) in Figure 4, regarding the cutting surface (26). This arrangement makes the cutting easier and enhances the movement of the tool.
  • the drive in the form of a transducer (30) (emitter) is the same, see Figure 7.
  • the cutting tool is started vibrating f-rom 20 to 40 Khz, with amplitudes of from a few hundreths to a few tenths of a millimeter, with higher or lower intensities, depending upon the material and the height of the cut, utilizing for this process the general principles of an ultrasonic procedure, as is, in itself, already known.
  • an ultrasonic generator (31) (Figure 1) is provided for, not shown in greater detail, which generates a sequence of electrical signals, which are transmitted by means of a cable (32) ( Figures 6 and 7) and a so-called convertor (34) of the transducer, which icon- vert the electrical signals into mechanical vibrations, which are transmitted to a booster (36), which has the special shape as seen in Figure 7.
  • a booster of this type is a mechanical amplifier.
  • the transducer (30) also includes a "Sonotrode” (38), on which the cutting tool is mounted.
  • Sonic energy is used.
  • One part of this is represented by the blade.
  • the geometric forms can also vary regarding the shape shown, depending upon the cut- tipg tool, to thus achieve an ideal adaptation, the booster and the Sonotrode thus form a coupling element.
  • FIGs 6 and 7 other details of the cutting head are shown.
  • a motor (60) which serves to adjust the blade around axle Z.
  • the motor (60) drives the cutting group defined in conjunction with 73 by means of cogwheels (63 and 65), See Figure 7.
  • cogwheels (63 and 65) For this purpose, the cogwheel (65) used as a pulley is joined to a hollow axle (67), rotating in a housing on the ball bearings (69 and 71), which, in turn, are located on the crossbar (66) of the unit (73).
  • the crossbar (66) is joined to the Y carrier (62). Also see Figure 3.
  • the cutting head (81) is thus moveable in the X or Y direction by means of carriers X and Y, described in relation to Figure 3; and in direction Z, fundamental. ly only the cutting tool, by means of carrier Z (75), previously described in relation to Figure 7, while the rotation of the cutting tool around axle Z takes place by means of the motor (60)
  • the control in the control apparatus (18) must be set in such a way that the rotation around axle Z is not over 360o or 2 x 360Q, for the purpose of avoiding a crossing of the cables and feeder lines; to the contrary, rotating joints would have to be used.
  • the cutting head has to be able to mvoe within these limits and with a free-run movement - for this purpose, without any cutting movements - to adopt the 0o position.
  • sliprings as couplers for the cables and feeder lines.
  • the cutting ehad also has a presser bar (79), by means of which the material to be cut, for example a cloth, is pressed down slightly,by the action of a spring (83),against the cutting surface (26).
  • a presser bar (79) by means of which the material to be cut, for example a cloth, is pressed down slightly,by the action of a spring (83),against the cutting surface (26).
  • the pressure bar is mounted on the hollow axle (67). in the area of the passing blade (106).
  • the spring (83) is supported by a base (89), also mounted on the hollow axle.
