DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an induction heating roller device.

[0002]

2. Description of the Related Art In an induction heating roller device, an induction heating mechanism is installed inside a hollow roller, both ends of the roller are closed by flanges, and a drive shaft integral with the flange is rotatably supported on a machine base. Further, a configuration in which both sides of the induction heating mechanism are supported by support rods, the support rods are inserted into the inside of the drive shaft, and a bearing is interposed between the two is already well known.

FIG. 8 shows the configuration, wherein 1 is a roller, 2
A and 2B are flanges for closing both ends of the roller 1 and are fixed to the roller 1 by bolts 3A and 3B. 4A, 4
B is a drive shaft integral with each of the flanges 2A and 2B, and is rotatably supported by the machine base via bearings (not shown) installed on the outer periphery thereof.

[0004] Reference numeral 5 denotes an induction heating mechanism, which comprises an iron core 6 and an induction coil 7 wound therearound. 8
Is a lead wire connected to the induction coil 7, which is led out and connected to an AC power supply. 9A and 9B are support rods connected to both ends of the induction heating mechanism 5 and supporting the same. The support rods are inserted through the drive shafts 4A and 4B, and the bearings 10A and 1
OB intervenes. Thereby, the support rods 9A, 9
B, that is, the drive shafts 4A and 4B are rotatable in a state where the induction heating mechanism 5 is stationary.

[0005] Incidentally, this type of apparatus is sometimes used for processing for forming a pattern on a sheet such as paper, nonwoven fabric, or iron plate. For this purpose, the outer periphery of the roller 1 is engraved with a pattern as necessary. However, when processing a different pattern, another roller having the engraved pattern must be used. For that purpose, the roller 1 needs to be replaced.

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

Next, a bolt 3B is attached to the right drive shaft 4B.
Then, the connection between the flange 2B and the roller 1 is released, the inner retaining ring 12 is removed, and the flange 2B and the drive shaft 4B are moved to the right side of the roller 1 to be separated from the roller 1. Thereafter, the induction heating mechanism 5 is connected to the support rods 9A, 9A.
Pull out from roller 1 together with B. FIG. 9 shows the state at this time. Reference numeral 13 denotes an outer retaining ring.

As a result, the roller 1 is separated from the other components. The roller 1 is replaced with another roller 1 prepared separately, and the components are assembled in the reverse procedure of the separation.

However, according to such a separating procedure, since the flanges 2A and 2B are closely fitted to the roller 1, it is not easy to remove each flange from the roller 1 and each drive shaft 4A. , 4B to bearings 10A, 10B
At the same time, when the bearings 10A, 10B separate 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. Since the roller 1 may fall on the inner surface of the roller 1, it must be carefully operated.

When assembling after replacing the roller 1, the induction heating mechanism 5 is inserted into the roller 1 together with the support rods 9A and 9B, and the support rods 9A and 9B are inserted.
Is fitted to the bearings 10A, 10B in the drive shafts 4A, 4B, but the fitting is not easy, and the flanges 2A, 2B are then attached to the roller 1 in this fitted state. The work is extremely cumbersome as it must be done.

That is, the work of attaching and detaching the roller and the flange is performed by the following three steps: the tight fitting of the roller and the flange; and the driving 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 complicates these tasks.

[0012]

SUMMARY OF THE INVENTION The present invention relates to an induction heating roller device provided with a roller, a driving shaft integral with a flange and a support rod integral with an induction heating mechanism. For the purpose of facilitating the work.

[0013]

According to the present invention, a roller and a flange are fastened by taper fitting, and a drive shaft and a support rod are temporarily fastened integrally when the roller and the flange are detached. Means, a support means for supporting one drive shaft, and a transport in which one of the drive shafts is supported by the support means and a roller whose fastening with a flange is released is mounted and transported along the other drive shaft side Means are provided.

[0014]

Since the roller and the flange are fastened by taper fitting, if the fastening is released, the flange can be separated from the roller by a slight movement, and the flange and the roller can be slightly separated during assembly. If they are fitted, the two will be closely fitted by the fastening.

When the roller and the flange are detached from each other, the drive shaft and the support rod are integrally fastened. Therefore, the drive shaft integral with the flange and the support rod integral with the induction heating mechanism are integrated with each other. It is possible to pull out and insert from the roller without breaking the positional relationship. Therefore, the work for attaching and detaching to and from the roller becomes extremely easy.

The drive shaft, flange, support rod, and induction heating mechanism are integrally supported by the support mechanism in a cantilever manner. Therefore, the roller whose fastening with the flange is released can be easily carried in and out while being mounted on the transport mechanism.
