  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a side view showing a slit coil handling apparatus according to an embodiment of the present invention, and FIG. 2 is a perspective view showing an essential part thereof. The slit coil handling apparatus 100 is connected to a crane body (not shown), and has a function of lifting and transporting the slit coils and separating the slit coils into individual strips. The main body 4 of the handling apparatus 100 has a U-shape including an upper frame 4a extending in a substantially horizontal direction, a side frame 4b extending in a substantially vertical direction, and a lower frame 4c extending in a substantially horizontal direction (C hook). . And the base member 5 is attached on the lower frame 4c, This base member 5 is the center of the slit coil 1 on the mounting base 2 when the handling apparatus 100 moves to a horizontal direction by the action | operation of a crane main body. It is inserted into the space 1s. In addition, 3 in FIG. 1 is a connection part with a crane main body, 11 is a balance weight.

  As shown in FIG. 2, guide rails 6 are provided on the upper surface of the base member 5 along the longitudinal direction (insertion direction). Six support sliders (support members) 7 a, 7 b, 7 c, 7 d, 7 e, 7 f are provided so as to be slidable along the longitudinal direction of the base member 5. The support sliders 7a to 7f are connected to each other by a wire 8, and the support sliders 7a to 7f are constrained to each other by the wire 8 when the adjacent sliders are separated by a predetermined length. . As shown in the drawing, the wire 8 is in a slack state in an initial state in which the support sliders 7a to 7f are integrally disposed and are not separated from each other. The upper surfaces of the support sliders 7a to 7f are curved according to the curvature of the central space 1s of the slit coil 1.

  A ball screw 9 extending in the horizontal direction is screwed to the support slider 7a provided at the tip. A motor 10 for rotating the ball screw 9 is attached to the base member 5. The other support slider is formed with a hole into which the ball screw 9 can be inserted when the support slider 7a is driven by the motor 10 and moved in the distal direction.

  As shown in FIG. 3 (a), the support sliders 7b to 7f (only 7b to 7d are shown) are filled with the filling members 12b to 12f so as to be accommodated in the support sliders 7a to 7e, respectively. As shown in FIG. 3 (b), the filling members 12b to 12f are filled with the support sliders 7b to 7f to support the slit coil 1 when the support sliders 7b to 7f are separated from each other. The slit coil 1 is prevented from rolling when separated into pieces.

  Next, the operation of the slit coil separating apparatus 100 configured as described above will be described with reference to the flowchart of FIG. 4 and the operation explanatory diagrams of FIGS.

  (Step 1) First, as shown in FIG. 5, the slit coil 1 with a vertical band (here, slit into six coil pieces 1 a to 1 f) is placed at a predetermined position on the mounting table 2. Put.

  (Step 2) Next, as shown in FIG. 6, the handling device 100 is moved in the horizontal direction by the operation of the crane body, thereby inserting the base member 5 into the central space 1 s of the slit coil 1.

  (Step 3) Next, as shown in FIG. 7, the handling device 100 is moved upward by the operation of the crane body, so that the slit coil 1 is supported by the support sliders 7a to 7f.

  (Step 4) From this state, as shown in FIG. 8, the support sliders 7a to 7f are separated from each other, and the slit coil 1 is separated into coil pieces a, b, c, d, e, and f accordingly.

  The procedure at this time will be described in detail with reference to FIG. In FIG. 9, it is assumed that the slit coil 1 is slit into five coil pieces 1a to 1e. First, the ball screw 9 is rotated by the motor 10, and the leading support slider 7 a is moved along the guide rail 6. Along with this, among the slit coils 1, the leading coil piece 1a, which is mainly on the support slider 7a, moves with the movement of the support slider 7a and is separated from the adjacent coil pieces 1b (FIG. 9). (A)). When the support slider 7a further moves and is separated from the support slider 7b by a predetermined length, the lighter 8 between the support sliders 7a and 7b is stretched, and the support slider 7b also starts to move. In this way, the sliders 7c, 7d, 7e, and 7f move sequentially in the same manner, and the other coil pieces 1b, 1c, 1d, and 1e are mainly weighted among the support sliders 7c, 7d, 7e, and 7f. 9b, and moves through the state shown in FIG. 9B, and is separated into five coil pieces 1a, 1b, 1c, 1d, and 1e as shown in FIG. 9C.

  (Step 5) After the slit coil 1 is separated into the respective strips of the coil pieces 1a to 1f, the coil pieces are bound and bound by performing horizontal banding. In this case, it is preferable to use a device for automatically winding and binding a band (wire or the like), but it may be performed manually by the operator.

  According to the present embodiment, as described above, by moving the support sliders 7a to 7f, the slit coil 1 can be separated without intervention of an operator, and it is safe and the support slider 7a located at the tip is driven. However, the other support sliders 7b to 7f are sequentially moved at a predetermined distance, and the coil pieces 1a to 1f of the slit coil 1 are separated accordingly, so that the slit coil 1 can be separated efficiently and quickly. Can do. Further, since the slit coil 1 can be separated only by driving the support slider 7a, a large-scale mechanism is unnecessary and a compact configuration can be achieved. Furthermore, since the slit coil 1 can be separated in a state in which the slit coil 1 is lifted and transported, the transport work between processes can be omitted, and the work process can be shortened.

  The present invention can be variously modified without being limited to the above embodiment. For example, as a restraining mechanism for restraining adjacent ones of support sliders that are support members in a state where they are separated from each other, a wire connecting adjacent support sliders is used, but not limited thereto, a chain or other thread-like element is used. May be used. Further, as shown in FIG. 10, the connecting portions 13 are provided so as to protrude from the support sliders 7 b to 7 f, respectively, and the hollow portions 14 into which the connecting portions 13 are inserted into the support sliders 7 a to 7 e and the connecting portions 13, respectively. When the support sliders 7a to 7f are integrally provided without being separated from each other, as shown in FIG. 10A, the connecting portion 13 is a hollow portion. 14, when one of the adjacent support sliders is separated by a predetermined length as shown in FIG. 10B, the tip of the corresponding connecting portion 13 is locked to the locking portion 15. Also good. In this case, the connecting part 13 can also function as the above-described filling part. Further, as shown in FIG. 11, the support sliders 7b to 7f are provided with cutout portions 16, and when the adjacent support sliders are separated by a predetermined length, the engaging portions 17a at both ends of the connecting pin 17 that connects them are provided. You may make it latch on each notch part 16 of these support slurders which adjoin each other.

  In the above embodiment, the ball screw mechanism is used as the mechanism for driving the support slider. However, the present invention is not limited to this, and other drive mechanisms such as a belt drive mechanism and a chain drive mechanism may be used. The tip of the supporting slider to be driven is used. However, the present invention is not limited to this, and at least one supporting slider may be driven.

  Further, in FIG. 9, when all the coil pieces of the slit coil are separated, the support slider is also separated, but the presence / absence of the support slider and the separation distance are influenced by how the slit coil is mounted. For example, as shown in FIG. 12, when the coil pieces are evenly riding on the two support sliders, the two support sliders may not be opened (the support sliders 7c and 7d and the coil piece 1c). In some cases, the support sliders adjacent to each other may not be completely separated from each other.

  Further, as shown in FIG. 13, by attaching a connecting hook 18 and a locking tool 19 to each of the support sliders 7a to 7f, and appropriately hanging the connecting hook 18 on the locking tool 19 of the adjacent support slider, the support sliders are attached. You may enable it not to leave a gap. Thus, when separating the wide coil pieces, only the necessary support sliders can be separated and separated into the respective coil pieces, and the working time can be shortened.

  Furthermore, in the above embodiment, the support slider that slides on the guide rail is used as the support member. However, as long as the support slider can move in the separation direction of the slit coil, not only the slider but also other movement modes that run on wheels or the like are used. It may be.
