The elevating body 54 is slidably fitted to guide rails 55 a, 56 a, 57 a, 58 a vertically arranged on four columns 55, 56, 57, 58. The box body 43 is fixed above and below each of the four columns 55, 56, 57, and 58 of the columns 55, 56 on the loading / unloading side of the mounting table 21.

The elevating means 51 includes a wire 60 fixed to the elevating body 54, a plurality of pulleys 61 around which the wire 60 is wound, and a drive motor 62 for rotationally driving one of the pulleys 61. Consists of.

As a result, the receiving table 50 has a loading position for receiving the loaded loading table 21, a standby position for separating the loading table 21 from the bobbin 20 when the wire rod of the bobbin 20 is wound, and a loading table 21. Can be switched to the carry-out position for sending out.

Further, the receiving table 50 is provided with an expanding / contracting mechanism 63 that is expandable / contractible in a direction orthogonal to the carrying-out direction of the mounting table 21 and slides the feeding position of the mounting table 21 by the drive roller 52.

As shown in FIGS. 6 and 7, the telescopic mechanism 63 includes a first sliding body 64 slidably fitted in the central opening 54 a of the lifting body 54, and a central opening 64 a of the first sliding body 64. A second slide body 65 slidably fitted to the support frame 53 and holding the support frame 53; and an extension / contraction drive means 66 for moving the first and second slide bodies 64, 65 in a direction orthogonal to the unloading direction of the mounting table 21. Become.

A plurality of guide rollers 70 for smoothly sliding the first sliding body 64 are attached to the central opening 54 a of the elevating body 54.

The outer side of the first sliding body 64 contacts the guide roller 70 of the elevating body 54, and the inner side of the first sliding body 64 contacts a plurality of guide rollers 71 attached to the side wall of the second sliding body 65.

The second sliding body 65 is provided with a stopper 72 for stopping the mounting table 21 fed from the mounting table moving means 23 to the receiving table 50 at a fixed position on the drive roller 52.

As a result, the receiving table 50 can be switched from the contracted state as shown in FIG. 5 to the extended state as shown in FIG. 6, and the mounting table 21 on which the bobbin 20 after winding the wire rod is mounted. It can be sent from three locations. At this time, it is desirable to dispose the mounting table moving means 23 on the lower side at positions where the mounting table 21 is sent out.

The drive motor 35 for loading and unloading the mounting table 21, the drive motor 62 for raising and lowering the receiving table 50, the drive motor for the drive roller 52, and the wire rod winding machine 22 are controlled by a controller to a predetermined moving body. Driven according to the sequence.

In the above-mentioned configuration, the empty wire rod winding bobbin 20 is placed on the placing table 21, and the flange 26 is inserted into the inserting groove 28 between the outer positioning piece 30 and the inner positioning piece 31 to be positioned. Make a decision. When this mounting table 21 is mounted on the roller portion 32 of the upper mounting table moving means 23 and the drive motor of the drive roller 52 and the upper drive motor 35 are driven to move the chain 33 in a circular motion, the small roller 41 is moved. Rolls on the guide rail 36, and the large roller 40 rotates accordingly.

The rotation of the large roller 40 moves the mounting table 21 in the direction of the wire winding machine 22 and guides it onto the rotationally driven drive roller 52 of the receiving table 50 at the loading position. When the mounting table 21 comes into contact with the stopper 72, the drive motor of the drive roller 52 and the upper drive motor 35 stop, and the mounting table 21 stops at a fixed position.

Here, the pivot is inserted into the central hole 26a of the bobbin 20 to hold the bobbin 20, and the receiving table 50 is lowered to the standby position to separate the mounting table 21 from the bobbin 20. When the bobbin 20 rotates due to the rotation of the pivot, the wire rod is wound around the winding drum 25 of the bobbin 20.

After the winding is completed, the receiving table 50 is raised again to mount the bobbin 20 on the mounting table 21, the pivot is removed from the central hole 26 a, and the bobbin 20 is positioned on the mounting table 21. The pedestal 50 is lowered to the carry-out position, the lower drive motor 35 is driven, and the driving table 52 sends the mounting table 21 onto the roller section 32 of the lower mounting table moving means 23, and the roller section. 32 is carried out in the opposite direction as at the time of carrying in.

In this way, the bobbin 20 can be positioned simply by placing the wire rod winding bobbin 20 on the mounting table 21, and the bobbin 20 can be carried in and out by moving the mounting table 21. be able to. Therefore, it suffices to provide a simple mechanism for moving the mounting table 21, the conventional engaging body can be eliminated, and the manufacturing cost can be reduced. Further, since it is not necessary to perform the positioning work between the central hole of the bobbin and the shaft portion of the engaging body as in the conventional case, and the number of the bobbins 20 that can be loaded and unloaded is not limited, the working efficiency is improved.

Further, when the bobbin 20 after winding the wire rod is carried out, the bobbin 20 is positioned on the mounting table 21, so that the wound wire rod collapses as compared with the case where the bobbin is rolled and carried out. There is no problem, and stable unloading is possible.

The present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

For example, the mounting table moving means 23 may be only one of the upper side and the lower side. Further, a pair of left and right fitting grooves may be formed on the upper surface of the mounting table 21 at positions corresponding to the flanges 26, and the side walls of the fitting grooves may serve as the restricting body.

[0045]

[Effect of device]

 As is clear from the above description, according to claims 1 and 2 of the present invention, the bobbin can be positioned only by placing the wire rod winding bobbin on the mounting table, and the bobbin can be moved by moving the mounting table. It can be loaded or unloaded. Therefore, the conventional engaging body can be eliminated, and the manufacturing cost can be reduced with a simple mechanism.

Further, unlike the conventional case, there is no need for positioning work for the central hole of the bobbin and the shaft portion of the engaging body, and the number of bobbins that can be carried in or carried out is not limited, so that work efficiency is improved. .

Further, when the bobbin after winding the wire rod is carried out, compared with the case where the bobbin is rolled out and carried out, there is an excellent effect that the wound wire rod is not collapsed and stable carrying out is possible. .
