2. Description of the Related Art As one type of bottomed composite insulation pipe, a bottomed metal pipe and a cylindrical inner peripheral insulating coating formed of a sheet-shaped insulating material and located along the inner periphery of the metal pipe. Members,
A flat plate-shaped inner bottom insulating covering member formed of a sheet-shaped insulating material and located along the inner bottom portion of the metal pipe, and a tube formed of a sheet-shaped insulating material and located along the outer periphery of the metal pipe. There is a bottomed composite insulation pipe made of a sheet-shaped outer insulation coating member and a flat outer insulation coating member formed of a sheet-shaped insulation material and located along the outer bottom portion of the metal pipe.

Composite insulation tubes of this type are used, for example, as containers for containing sodium-sulfur batteries. In a container containing a sodium-sulfur battery, a tube made of aluminum or an aluminum alloy having high corrosion resistance to sodium polysulfide is adopted as a metal tube, and as a sheet-shaped insulating material constituting each insulating coating member, Mica sheet is adopted.

In the assembly of the composite insulating tube, as shown in FIG. 17, a sheet-shaped insulating material such as a mica sheet is wound a predetermined number of times around the outer circumference of a metal tube 1 such as aluminum, and its ends are adhered to form a tubular shape. The outer peripheral insulation coating member 2 is formed, and a flat plate-shaped outer bottom insulation coating member 3 made of a sheet-shaped insulation material is attached to the outer bottom portion of the metal tube 1, while a flat plate-shaped inner insulation material is formed. It is performed by inserting the bottom insulating cover member 4 and the inner peripheral insulating cover member 5 formed into a tubular shape by winding a sheet-like insulating material into the metal tube 1 and adhering the same to the composite insulation by dust. The tube 6 is assembled.

[0005]

By the way, since the assembly of the composite insulating tube 6 is carried out by hand, it is very troublesome. In particular, in order to form the inner peripheral insulating coating member 5, after the sheet-shaped insulating material is wound in advance and formed into a tubular shape with a curl, it is inserted into the metal tube 1 and then inside the metal tube 1. In addition to the troublesome manual work of expanding, the inner peripheral insulating coating member 5 is difficult to fit on the inner peripheral surface of the metal tube 1 by simply expanding it, and the sheet-shaped insulating material has considerable rigidity such as mica sheet. When using a certain insulating material, it is difficult to have a winding tendency even if it is wound, and if the winding is done manually, the insulating material is likely to be damaged. There is a problem that it is easy to damage even when pushing out. It is also difficult to wind the sheet-shaped insulating material with high dimensional accuracy to form the inner peripheral insulating coating member 5.

Therefore, in assembling the composite insulating tube 6, it is preferable to solve the above problems by mechanically forming the inner peripheral insulating covering member 5 without any manual work. An object of the present invention is to provide an assembling method and an assembling apparatus capable of solving each of these problems in assembling the composite insulating tube.

Insulate the inner surface. Moreover, the inner bottom insulating coating 13 is
Since the inner diameter of the aluminum tube 11 is substantially the same as the inner diameter of the aluminum tube 11,
It is sandwiched between the inner bottom surface and one end edge portion of the inner peripheral insulating coating member 12b, and is held without being separated from the inner bottom surface.

In the transfer device 50, after the inner peripheral insulating coating 12b and the inner bottom insulating coating 13 are separated from the winding jig 31, the drive motor 52 is driven to move to the original position and return. Further, in the gripping device 60, the lifting cylinder 63 is driven to raise the tube pressing tool 62 to open the aluminum tube 11. The opened aluminum tube 11 is transferred to the winding device 73 in the fourth step (IV) shown in FIG. 2 by the transfer mechanism 64 for the aluminum tube 11.

In the fourth step (IV), the mica sheet 14a for forming the outer peripheral insulating coating member 14b is supplied from the mica sheet supplying device 71 onto the conveying path 70, and the tip portion of the mica sheet 14a and The double-sided adhesive tape 14c supplied from the tape supply device 72 is attached to the terminal portion.
14d is bonded and conveyed to the winding device 73. In the winding device 73, the mica sheet 14a is wound around the outer periphery of the aluminum pipe 11 conveyed by the conveying mechanism 64, and the mica sheet 14a is covered with the double-sided adhesive tapes 14c, 14c.

The mica disk 13 is adsorbed and held at the opening edge of the one end opening of the formed inner peripheral insulating covering member 12b, and the inner peripheral insulating covering member 12b and the mica disk 13 are wound by the winding jig 31.
Together with this, it is inserted into the aluminum tube 11. The inner peripheral insulating coating member 12b and the mica disk 13 on the winding jig 31 are released from the winding jig 31 by the action of the reaction force by eliminating the suction force of the winding jig 31, and the aluminum pipe 11 is removed. The pipe 11 is brought into contact with the inner peripheral surface and the inner bottom surface.
The inner peripheral surface and the inner bottom surface of the are coated with insulation.

Therefore, according to the assembling method and the assembling apparatus, the mica sheet 12a is preliminarily wound to form a tubular insulating coating member, and the tubular insulating coating member is placed inside the aluminum pipe 11. Does not require a troublesome manual work such as a manual work for inserting the inner peripheral insulation coating member 12b into the inside thereof and arranging the inner peripheral insulation coating member 12b along the inner peripheral surface of the aluminum pipe 11. At the same time, the inner peripheral insulating covering member 12b can be formed with high dimensional accuracy, and the inner peripheral insulating covering member 1 can be formed at the time of forming the inner peripheral insulating covering member 12b and arranging it on the inner peripheral surface of the aluminum pipe 11.
There is no risk of damaging 2b.

Further, if the winding jig 31 of this embodiment is adopted, when the mica sheet 12a is wound around the winding jig 31, the tip of the mica sheet 12a is first fed with a small number of negative pressure supply ports. Winding jig 31 by negative pressure from the group 31e2
Of the mica sheet 12a which is sucked onto the outer periphery of the mica sheet 12a and is gradually abutted by the rotation of the winding jig 31.
1e1 is sucked onto the outer circumference of the winding jig 31 by the negative pressure action, and finally the terminal portion of the mica sheet 12a is sucked by the negative pressure action from the group of a small number of negative pressure supply ports 31e3. By adsorbing to 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 in a tubular shape around the outer circumference of the winding jig 31 and held, and especially the tip end and the end of the wound mica sheet 12a are the outer circumference of the winding jig 31. It does not come off or get damaged.
