Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used as a heat insulating member for covering the outer peripheral portion of a heat-insulated pipe such as a heat medium feeding pipe for air conditioning, and a slit portion is formed in the pipe length direction. The present invention relates to a method for producing a coated heat insulating tubular body with a skin sheet and an apparatus therefor.

[0002]

2. Description of the Related Art A coated heat insulating tubular body of this type is formed into a C-shaped cross section having a slit portion in the tube length direction of a thick tubular body made of foamed resin, and is attached to the outer surface of the thick tubular body. A fin-shaped portion is formed along one of the slits at one end of a skin sheet made of the resin film. Therefore, since the tubular body can be expanded and contracted in its diameter, it is possible to easily insert the heat-insulated tubes of various sizes through the slit portion if the diameter of the heat-insulated tube is within a predetermined range. Also, if the separator of the fin-shaped part is peeled off and the exposed adhesive coating surface is overlaid on the back surface of the facing skin sheet, the slit part will be covered automatically, and the heat-insulated tube and the insulation insulation will be covered. It can be easily integrated with the tubular body.

Conventionally, this type of manufacturing method for a coated heat-insulating tubular body is generally carried out by a typical manual work, and specifically, as shown in FIG. 7, each is rotatable and parallel. Three
One (first to third) roll A, B, C is provided, and two (second and third) rolls B, C of them are arranged on a predetermined work surface, while the remaining one is A book (first) roll A is provided movably in the direction of arrow p.

In this state, the first worker
8 in a state in which the roll A of FIG.
As shown in FIG. 4, a skin sheet D cut into a predetermined width and a predetermined length is prepared, and then the second worker except the separator remaining portion Ea corresponding to the fin portion Db in the sheet width direction of the separator E. The portion Eb (peeling portion) is peeled off to expose the adhesive application portion Da. After that, the other end of the skin sheet D in the sheet width direction, that is, the sheet end of the exposed adhesive-coated portion Da opposite to the fin-shaped portion Db is positioned on the first roll A. Put on.

Then, between the two rolls B and C, a cylindrical tubular body F made of foamed resin and having a predetermined pipe length is placed so that the pipe length direction is along the roll length direction of both rolls B and C.

Then, the first roll A is brought closer to the second and third rolls B and C, and the second roll B is rotated while the roll surface of the cylindrical tubular body F is in contact. .. As a result, the cylindrical tubular body F sandwiched between the rolls A, B, and C is rotated together, and the adhesive exposed portion Da of the skin sheet D is attached to the outer surface of the tubular body F. The adhesive exposed portion D
When all the sticking of a is completed, the first roll A is moved to take out the coated heat-insulating tubular body which is the product having the outer skin sheet D stuck on the outer periphery thereof.

[0007]

However, according to the above-mentioned conventional methods, the manual work is dominant over all, and at least two skilled workers are required to increase productivity. In addition to the heavy physical labor, the length of the product is used for roll A,
Since the lengths of B and C are restricted, it is impossible to manufacture a roll having a length exceeding at least the roll length of each roll A, B, and C.

Also, the skin sheet 9 is attached to the outer peripheral surface. The curved and deformed sheet body 7B is abutted at both end portions in the sheet width direction, and one of the both end portions is heated by the seal blade 28. The heated end portion is heat-sealed to the opposite end portion, so that the heat insulating sheet body 7 becomes a primary semi-finished product pipe body 16 which is a cylindrical pipe body.

A slit portion 7a is formed in the pipe body 16 in the pipe length direction along the base of the fin-shaped portion 9b by the dividing mechanism 29 to obtain a secondary semi-finished product pipe body 17. The subsequent cutting and packaging steps are the same as those in the first embodiment.
