The reversing position of the traversing carriage 23 is an example, and any position may be used as long as it does not come into contact with other components. Thereafter, the other axle end Sa is moved to the wheel holding device R side, and the other wheel W is depressurized by the depressurizing device U by the above-described operation. The depressurizing operation and the transfer and unloading of the depressed wheel W are the same as the depressurizing, transferring, and unloading operations described above, and thus the detailed description is omitted.

Since the discarded wheels W pulled out by the wheel set depressurizing device M in this manner are carried out in a state of being set up on the wheel rack 14, the labor and time required for carrying out the discarded wheels W are greatly reduced. Can be reduced.

As described above, the axle holding device T is configured to be reversible, and the wheel holding device R and the device for carrying out the wheel W are provided on one side thereof. Can be depressurized and carried out, so that the apparatus configuration can be simplified and the apparatus can be downsized, so that the installation space can be reduced.

FIG. 10 is a front view of a wheel axle press-in device showing a second embodiment of the present invention. In this example, the first
In the embodiment, the depressurizing device U provided in the device frame 4 is changed to a press-fitting device Y to constitute a wheel axle press-fitting device N. In this case, the new wheels W are transferred by the reverse flow of the flow transferred from the wheel holding device R to the wheel lifting device E via the wheel transfer device P and stored in the wheel rack 14. A cylinder 43 with a speed adjusting mechanism or the like is used as the press-fitting device Y, and the wheel W is press-fitted through a press-fitting block 44 having a return spring 44a provided in the wheel holding device R. At a predetermined position of the other device frame 4, a receiving block 45 for supporting the axle end when the wheel is press-fitted is provided. Since other configurations are the same as those of the above-described wheel axle depressurizing device M, the same configurations are denoted by the same reference numerals, and detailed description thereof will be omitted.

According to the wheel axle press-in device N, new wheels W stored in the wheel rack 14 shown in FIG. 2 are supported by the rod 31 provided on the manipulator 19 of the wheel elevating device E, and are transferred upward. By closing the wheel receiving rail 15 at a predetermined position, the wheel W is held at a predetermined position of the lifting device E. In this state, the rod 31 of the manipulator 19 is stored, and as shown in FIG.
Is transferred from the wheel receiving rail 15 onto the transfer rail 12 by the rod 42 of the transfer arm 40 provided on the transfer arm 40, and is transferred to a predetermined position on the transfer rail 12. This position is a predetermined position of the wheel holding device R and a press-fit position of the wheel W.

The wheels W held in this state move to the axle holding device side together with the wheel holding device R in a state where the traversing carriage 23 traverses to the wheel holding device side and the axle end contacts the receiving block 45. The pressing is performed by a press-in block 44 pressed by a cylinder 43 of the press-in device Y. At this time, the dimension of press-fitting the wheel from the end of the axle is controlled by a sensor (not shown).

When the wheel W is pressed into one end of the axle in this way, the wheel holding device R moves backward, and the traversing carriage 23 moves to the predetermined position of the traveling carriage 3 (for example, "traveling position").
To the horizontal reversing mechanism H provided on the
As a result, the axle S is turned (reversed) by 180 ° (FIG. 4). Then, the wheel holding device R is moved to the other axle end Sa.
Move, and the wheel W is press-fitted by the press-fitting device Y.

The new wheel W supplied to such a wheel axle press-in device N is processed into a size corresponding to the axle diameter after the abandoned wheel W has been removed by the above-described wheel axle depressurizing device M, and is carried in. For this reason, by storing it in a state of being set up on the wheel rack 14 after being processed by the middle grinding machine, the labor and time required for carrying in the new wheel W can be greatly reduced.

In the above-described first and second embodiments, the wheel axle press-off device M and the wheel axle press-in device N have been described. However, the wheel axle press-in device M is provided upstream of the rail 2 and the wheel axle press-in device is provided downstream. If N is provided, the axle S to which the wheel W to be replaced is attached is held by the axle holding device T and moved along the rail 2 so that the wheel axle depressing device M depresses the waste wheel W. Then, it is possible to configure a wheel axle attaching / detaching device in which a new wheel W is press-fitted by the wheel axle press-fitting device N to the axle S which is transferred in a state where only the axle S is provided.

Furthermore, if a control device (not shown) for controlling such a flow is provided, it is also possible to automatically control from depressurization to press-fitting of the wheel W, and it is also possible to constitute an automatic wheel set attaching / detaching device. it can. This control device can be constituted by a device having a microcomputer or the like.

As described above, both the wheels W can be depressurized or press-fitted by one measurement of the axle holding device T for transporting the axle S, so that the device can be downsized and the entire equipment can be saved. Space can be achieved.

Further, since the state of unloading the wheels W, unloading the discarded wheels at the time of press-fitting, and loading new wheels is "vertical", the operation of transferring the wheels W is not wasted, and the efficiency of the operation is reduced. Good work can be done.

The above-described embodiment is one embodiment, and various changes can be made without departing from the gist of the present invention, and the present invention is not limited to the above-described embodiment.

[0053]

The present invention is embodied in the form described above and has the following effects.

By making the axle holding device reversible in the horizontal direction, it is possible to perform the depressurizing or press-fitting operation of both wheels from the same direction. Alternatively, a press-fitting operation can be performed, and the wheel-shaft depressurizing device or the wheel-shaft press-fitting device can be reduced in size. Thereby, it can be manufactured at low cost.

Further, since the wheels are kept in a vertical position when the wheels are carried out or carried in, the time and labor required for transferring the wheels can be greatly reduced.
