Is a lead wire connected to the induction coil 7, which is led to the outside and connected to an AC power supply. Reference numerals 9A and 9B are support rods that are connected to both ends of the induction heating mechanism 5 and support the induction heating mechanism 5. The support rods are inserted into the drive shafts 4A and 4B, and the bearings 10A, 1
0B intervenes. As a result, the support rods 9A, 9
B, therefore, the drive shafts 4A and 4B are rotatable while the induction heating mechanism 5 is stationary.

By the way, in this kind of apparatus, it is sometimes used for processing for forming a pattern on a sheet such as paper, non-woven fabric, and iron plate. For that purpose, the outer periphery of the roller 1 is engraved with a pattern as required, but when processing a different pattern, another roller engraved with the pattern must be used. For that purpose, it is necessary to replace the roller 1.

In order to replace it, the roller 1 is placed on a suitable base, and first the bolt 3A is attached to the left drive shaft 4A.
To remove the connection between the flange 2A and the roller 1,
And retaining ring 11 are removed, and flange 2A and drive shaft 4A
Is moved to the left of the roller 1 and separated from the roller 1.

Next, the bolt 3B is attached to the right drive shaft 4B.
The flange 2B and the roller 1 are disengaged, the inner retaining ring 12 is removed, and the flange 2B and the drive shaft 4B are moved to the right of the roller 1 and separated from the roller 1. After that, the induction heating mechanism 5 is attached to the support rods 9A and 9A.
Pull out from roller 1 together with B. FIG. 9 shows the state at this time. Note that 13 is an outer retaining ring.

As a result, the roller 1 is separated from the other constituent parts. Here, the roller 1 is replaced with another separately prepared roller, and the constituent parts are assembled in the reverse order of the separation.

However, according to such a separation procedure, since the flanges 2A and 2B are closely fitted to the roller 1, it is not easy to detach each flange from the roller 1, and each drive shaft 4A is not easily removed. , 4B bearing 10A, 10B
At the same time, when the bearings 10A, 10B are separated from the support rods 9A, 9B when they are separated from the support rods 9A, 9B, there is no support for the support rods 9A, 9B, so the support rods 9A, 9B are inclined, Since it may drop on the inner surface of the roller 1, its operation must be performed carefully.

When assembling the roller 1 after the replacement, the induction heating mechanism 5 is inserted into the roller 1 together with the supporting rods 9A and 9B, and the supporting rods 9A and 9B are inserted.
The tip of the is fitted to the bearings 10A and 10B in the drive shafts 4A and 4B, but the fitting is not easy, and then the flanges 2A and 2B are fitted to the roller 1 in this fitted state. The work is extremely cumbersome as it has to be installed.

That is, the work of attaching and detaching the roller and the flange is carried out by closely fitting the roller and the flange, and by using the drive shaft integral with the roller and the flange and the support rod integral with the induction heating mechanism. The fact that the components are separated separately makes these tasks cumbersome.
