  The present invention relates to a sheet material cutting apparatus and a cutting method for cutting various sheet materials such as carbon fiber, prepreg, CFRP, nylon sheet, and woven fabric.

  2. Description of the Related Art Conventionally, a sheet material cutting device that cuts a sheet material such as a laminated fabric material into a predesigned shape is known (for example, Patent Document 1).

  The sheet material cutting apparatus includes: a cutting table on which a bristle bed with air permeability is laid; a Y beam suspended on the cutting table so as to be movable along the X direction; and a Y direction along the Y beam. And a cutter head provided on the cutter head and capable of rotating and moving up and down.

  The sheet material sucked and held on the cutting table is cut by driving the Y beam, the cutter head, and the cutter according to shape data designed in advance by CAD or the like.

  By the way, among various sheet materials, carbon fiber related sheet materials (carbon fiber alone, prepreg, CFRP) are lightweight and high in strength, and are used in various industrial fields such as automobiles, wind turbines, and aircraft. Widely used. In particular, members used for aircraft have many long members, and accordingly, demands for cutting long carbon fiber-related sheet materials are increasing. In addition to carbon fiber-related sheet materials, there is an increasing demand for cutting sheet materials such as nylon and resin used for long applications.

  However, as described above, in the conventional sheet material cutting apparatus, when the Y beam is driven in the X direction, the power supplied to the cutting table main body is supplied to the Y beam by a plurality of cables. In order to cut a long carbon fiber-related sheet material, it is necessary to lengthen the cutting table and to increase the length of the cable. Further, in the cutter head and the cutter, many cables for sending control data are used for delicate cutting, and these cables are also laid down to the Y beam along the cutting table.

  However, when the cable is lengthened, there are problems that a plurality of cables bundled when the Y beam is moved are rubbed or a bending force is applied, so that the cable is disconnected or damaged. In addition, when the cable is lengthened, the weight of the cable also increases, and there is a problem that it becomes difficult to assemble the apparatus or carry it into the factory. In addition, when the cable is disconnected or damaged, there is a problem that it is difficult to specify a trouble location. Furthermore, it is necessary to move the Y beam at a high speed in order to improve the cutting speed, and it is difficult to move the Y beam at a high speed due to the influence of the weight of the cable and the friction with each part accompanying the movement of the cable. It was.

  In addition, when the sheet material cutting device is lengthened, it is necessary to enlarge the suction chamber of the cutting table, which is also an obstacle to the assembly of the device and the carrying into the factory. In addition, since the suction chamber must be enlarged as a whole (that is, the cutting table), the sheet material cutting apparatus once introduced into the factory can be used with another long sheet material. When applying to cutting, it was necessary to introduce another long device. On the other hand, when an apparatus used in a long length is to be applied to another short sheet material, it is necessary to introduce a new short apparatus.

  In addition, when the sheet material cutting device is lengthened, there are a wide range of parts for cutting the sheet material, so the operation part (for example, the installation part of the main body control computer) and the part that performs the cutting operation (the Y beam is positioned) In some cases, the distance between them is a considerable distance.

  Next, the connection structure of the table block 43 will be described with reference to FIGS. 5 (a), 5 (b) and FIG.

  5A and 5B are enlarged views of a part of the connection portion 44 of the table block 43 (note that the suction sheet 4 is not laid). As shown in FIG. 5A, the two table blocks 43 </ b> L and 43 </ b> R are configured to be separable at the connection portion 44. Support frames 30L and 30R having a substantially L-shaped cross section are provided on both sides of the table blocks 43L and 43R along the X direction in a separable manner. One end of the support frame 30R is formed so as to partially protrude from the table block 43R, and one end of the support frame 30L is formed to be recessed from the connection portion of the other table block 43L. When the table block 43 is the end of the cutting table 2, the support frame 30 </ b> R may be flat and end with an uneven shape.

  A fixing hole 30c is provided at the tip of the uneven portions of the support frames 30L and 30R. Further, the energization members 33 laid on the support frames 30L and 30R are formed to be separable from each other at the connection portion 44. Moreover, the notch part 30a is provided in the position corresponding to the electricity supply member 33 in the connection part 44 of the support frames 30L and 30R, respectively. In addition, fixing holes 30b are provided around the connection portions of the support frames 30L and 30R. The table frames 39 and 39 of the table blocks 43L and 43R are individually provided to form an independent suction chamber 40.

  Next, as shown in FIG. 5B, the table blocks 43L and 43R are brought into contact with each other. At this time, the convex portion of the support frame 30R is inserted into the concave portion of the support frame 30L, and the support frame 30L and the support frame 30R come into contact with each other.

  After the support frame 30L and the support frame 30R come into contact, the connection plate 45 is fastened with appropriate bolts or the like using the fixing holes 30b of the support frames 30L and 30R so as to support the side surfaces of the current-carrying member 33. The uneven portions of the support frames 30L and 30R are also fastened to the support frame 37 with appropriate bolts or the like using the respective fixing holes 30c.

  Next, the connection state of the energizing member 33 will be described with reference to FIG. FIG. 6 is a cross-sectional view of the connecting portion of the energizing member 33 as viewed from the front side. The energizing member 33 has two conductive rails covered with an insulating member 33a, and the insulating member 33a has an opening at a position corresponding to the notch 30a on the back surface side. The conductive block 46 having conductivity through the notches 30a and the openings comes into contact with the current-carrying members 33 and 33 so that the current-carrying member 33 of the connection portion 44 is conducted.

  Next, a second embodiment will be described with reference to FIG. 7 as a modification of the first embodiment. FIG. 7 is an enlarged view of a main part in which one end portion of the cutting table 2 is enlarged.

  When a current-carrying rail is used as the current-carrying member 33 and, for example, a conductive brush is used as the current collecting member 25 as in the first embodiment, shavings are generated because the conductive brush slides on the current-carrying rail. Since the shavings are also conductive, if too much shavings accumulate on the current-carrying rails, there is a possibility that the two current-carrying rails are connected and short-circuited. Therefore, in the second embodiment, a dust collection box 49 that collects shavings is provided at the end of the energization member 33 and a dust collection brush 50 is provided in the vicinity of the current collection member 25.

  The current collecting member 25 and the dust collecting brush 50 are integrally mounted on the same support frame 14b, whereby the energizing member 33 can be cleaned as the Y beam 3 moves. Note that when the energizing member 33 is provided downward, the dust collection box 49 is not necessary.

  Next, a third embodiment in which an induction wire 55 is used as a current-carrying member and power is received using an induction coil 56 will be described with reference to FIGS. 8 and 9 (in FIG. 8 and FIG. The same reference numerals are used for portions common to the embodiment).

  As shown in FIGS. 8 and 9, two guide wires 55 as current-carrying members are laid along the X direction of the support frame 30 on the support frame 30 provided on one side surface of the cutting table 2. The induction wire 55 is supplied with a high-frequency current from an inverter power supply 58 provided in the vicinity of the sheet material cutting device 1.

  Further, similarly to the first embodiment, a moving frame 14b that is movable integrally with the Y beam 3 is provided, and a power receiving unit 57 as a current collecting member is fixed to the moving frame 14b. The power receiving unit 57 has a built-in induction coil 56 that is movable in a non-contact state along the induction wire 55. When the induction coil 56 travels in a non-contact manner on the induction wire 55 in which a high-frequency current flows, the induction coil 56 receives an induced electromotive force from the magnetic flux generated around the induction wire 55 and receives power. Accordingly, the driving power of the Y beam 3 can be received in a non-contact manner as the Y beam 3 travels. Note that, similarly to the first embodiment, the driving power of the cutter head 5 and the driving power of the cutter 6 may be received without contact. Further, the power of the control device 34 for the Y beam 3 can also be received from the power receiving unit 52.

  The above is the embodiment of the present invention, but the present invention is not limited to the above-described embodiment, and appropriate modifications are possible within the scope of the invention.
