The present invention has been made to solve the above problems, and an object of the present invention is to obtain a roll device that can easily lead a lead wire to the outside.

[Means for solving problems]

A roll device according to the present invention includes a base that supports one end of a fixed shaft that extends through the cylindrical body connected to the roller and that extends to the outside, and that prevents the fixed shaft from rotating. A lead wire that forms a pair of flat portions that extend in the axial direction and is parallel to the vertical direction at one end of one side of the shaft, and that excites an electromagnetic coil that is led to the outside along the surface of the pair of flat portions. Is provided.

[Action]

In the roll device according to the present invention, the lead wire for exciting the electromagnetic coil can be led out to the outside along the surface of the pair of flat portions of the one end of the fixed shaft.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In each of these figures, (1) is a roller,
(2) is a cylinder, (5) is an electromagnetic coil, (6) is an iron core,
(7) is a bearing mechanism, (7a) is a bearing, (7b) is a bearing stand, and (14) is a fixed shaft, around which an electromagnetic coil (5) is wound via an iron core (6). (14a) is one end of the fixed shaft (14), and extends through the cylindrical body (2) to the outside. Reference numeral (14) is a pair of flat portions which are formed such that the one-side shaft end portions (14a) extend in the axial direction and are parallel to the vertical direction. (15) is a base for supporting one end of the fixed shaft (14) extending through the cylindrical body (2) to the outside and for preventing rotation of the fixed shaft (14) , (16) are electromagnetic coils (5) that are led out to the outside along the surface of the one-side shaft end (14a) of the fixed shaft (14) and connected to a power supply (not shown).
Is a lead wire that excites.

Next, the operation will be described. Turn on the power and turn the lead wire (1
The roller (1) is induction-heated by exciting the electromagnetic coil (5) through 6). One end (14a) of the fixed shaft (14) in the roller (1) extends through the inside of the tubular body (2) with a gap between the tubular body (2) and the outside. ,
It is supported by the base (15) and is prevented from rotating. The lead wire (16) for exciting the electromagnetic coil (5) is a pair of flat portions (14b) on one end of the fixed shaft (14) (14a).
It is led out along the surface. The fixed shaft (14) has one side shaft end (14a) and the tubular body (2) with a sufficient gap, and the lead wire (16) has one side shaft end of the fixed shaft (14). It is along the surfaces of the pair of flat portions (14b) of the portion (14a), and does not hinder the rotation of the roller (1) and the tubular body (2). Therefore, it is not necessary to form the central hole (12) along the axial direction inside the one side shaft end portion (4a) of the fixed shaft (4) as in the conventional case, and simplification can be achieved. Further, the lead wire (16) is connected to the fixed shaft (14) at one end of the shaft (14).
It only needs to go along the surface of a), maintenance can be performed easily, and workability is improved.

Further, as shown in FIGS. 3 and 4, the lead wire (1) is provided on the one side shaft end portion (14a) of the fixed shaft (14) with an appropriate interval.
By winding a holding body (17), which is made of, for example, a metal wire, a vinyl wire, or a string, which holds 6), the stability or workability of leading out the lead wire (16) is further improved.

In the above embodiment, the case where the support structure for the roller (1) and the support structure for the one side shaft end (14a) of the fixed shaft (14) are different structures has been described. It is needless to say that the present invention can be applied to the case where the bearing base (7b) of the bearing mechanism (7) is formed of the same structure.

〔The invention's effect〕

As described above, according to the present invention, the one end of the fixed shaft that extends through the cylindrical body connected to the rollers and extends to the outside is supported by the base, and the rotation of the fixed shaft is prevented. Since the lead wire for exciting the electromagnetic coil is led out to the outside along the surface of the pair of flat portions parallel to the vertical direction formed by extending in the axial direction at the one end of the fixed shaft. The lead wire can be easily led out to the outside, and the maintenance becomes easy.
