2. Description of the Related Art As one type of a bottomed composite insulating tube, a bottomed metal tube and a cylindrical inner peripheral insulating coating formed of a sheet-like insulating material and located along the inner periphery of the metal tube. Components,
A flat inner bottom insulating coating member formed of a sheet-like insulating material and positioned along the inner bottom of the metal tube; and a tube formed of a sheet-like insulating material and positioned along the outer circumference of the metal tube There is a bottomed composite insulating tube composed of an outer peripheral insulating coating member having a flat shape and a flat outer insulating coating member formed of a sheet-like insulating material and located along the outer bottom portion of the metal tube.

[0003] A composite insulating tube of this type is used, for example, as a container for accommodating a sodium-sulfur battery. In a container containing a sodium-sulfur battery, aluminum or aluminum alloy tubes having high corrosion resistance to sodium polysulfide are adopted as metal tubes, and sheet-like insulating materials constituting each insulating coating member are Mica sheets are adopted.

As shown in FIG. 17, a composite insulating tube is assembled by winding a sheet-like insulating material such as a mica sheet around a metal tube 1 made of aluminum or the like a predetermined number of times and bonding the end thereof to a cylindrical tube.

This is performed by inserting the bottom insulating cover member 4 and the inner circumferential insulating cover member 5 formed into a tubular shape by winding a sheet-like insulating material into the metal tube 1 and sticking them together. The tube 6 is assembled.

[0005]

However, since the assembly of the composite insulating tube 6 is all performed manually, it takes much time and effort. In particular, for forming the inner peripheral insulating covering member 5, a sheet-shaped insulating material is wound in advance and formed into a cylindrical shape with a curl, and then inserted into the metal tube 1 to be formed inside the metal tube 1. In addition to the troublesome manual work of pushing and spreading, the inner circumferential insulating covering member 5 is not easily adapted to the inner circumferential surface of the metal tube 1 only by the spreading work, and the sheet-like insulating material has a considerable rigidity such as a mica sheet. When using a certain insulating material, it is difficult to form a winding habit even when wound, and it is easy to damage the insulating material if the winding is performed manually. There is a problem that it is easy to break even in the work of spreading. Further, it is also difficult to wind the sheet-shaped insulating material with high dimensional accuracy to form the inner peripheral insulating covering member 5.

Therefore, in assembling the composite insulating tube 6, it is preferable to solve the above-mentioned problems by mechanically forming the inner circumferential insulating coating member 5 without troublesome manual work. An object of the present invention is to provide an assembling method and an assembling apparatus that can solve each of these problems in assembling the composite insulating tube.

The intermediate portion of the mica sheet 12a that gradually comes in contact with the outer periphery of the
1a1, the end of the mica sheet 12a is adsorbed to the outer periphery of the winding jig 31 by the negative pressure action from the group of the mica sheet 12a. By adsorbing on the outer periphery, the adsorbed state of all these parts can be maintained. Therefore, according to the winding jig 31,
The rigid mica sheet 12a can be accurately wound and held in a cylindrical shape around the outer periphery of the winding jig 31. In particular, the leading end portion and the terminal portion of the wound mica sheet 12a are formed around the outer periphery of the winding jig 31. It does not come off or break.
