Abstract

PURPOSE:To reduce the number of workers and improve the productivity by providing lifting means which comprises a hydraulic or electric motor mechanism and which elevates a raw sheet roll to a predetermined height position in the proximity of a roll frame which acts to unwind a heat insulating sheet from the raw sheet roll. CONSTITUTION:A raw sheet roll 49 placed in the rear of a slope table 50 is allowed to roll forward and mounted on the mounting table of a lifter 46 being descended to the lowermost position by a hydraulic or electric motor mechanism, wherein a roll shaft 61 is passed through a paper core pipe. Subsequently, the lifter 46 is permitted to ascend to the position in which the roll shaft is in approximately the same height as the support rail 44 of an unwind roll 49 and, following this, the raw sheet roll 49 is made to roll forward. The raw sheet roll to be used is moved to the position of a bearing part in the front end part of the support rail 44. The bearing part is made up of a rotating disc body and, moreover, since the top position of the roll is in approximately the same as the support rail 44, the small diameter part of the roll shaft 61 moves readily smoothly over the rotating disc and thus it can be stabilized between the rotating discs.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-bonding or laminate of a laminate composed of a metal plate such as a steel plate and a heat insulating sheet member (especially long and wide member) such as foamed plastic material or glass fiber material. The present invention relates to a laminating device for manufacturing with an adhesive.

[0002]

2. Description of the Related Art Conventionally, as a laminating apparatus of this type, for example, as described in Japanese Patent Publication No. 58-40492.
A method is known in which a heat insulating sheet body (heat insulating sheet body) made of a foamed plastic material or the like fed from a roll is automatically adhered to a steel plate or the like (raw plate). The steel plate is run from the carry-in port to the carry-out port of the body (drying oven), the steel plate carried out from the carry-out port and the heat insulating sheet body are laminated between the pressure bonding rolls, and the laminated heat insulating sheet body is formed into an appropriate shape. After cutting and removing, the steel plate laminated with the heat insulating sheet is cut.

In this case, the original roll is usually formed by mounting a long and wide heat insulating sheet body and has a considerable load weight. Therefore, the original roll is arranged at an upper position of the apparatus through an appropriate roll mount mechanism. On the other hand, of course, since the length of the heat insulating sheet body mounted is limited, it is necessary to replace it with another original roll when all of it is unwound.

As the roll mount mechanism, there is one which is attached to the top of the columnar body as described in the above publication, but with such a structure, the replacement work of the original roll is extremely troublesome, and the worker also needs a considerable amount of physical strength. Multiple people are required.

FIGS. 7 and 8 show an example of the structure of a conventionally known roll mount mechanism in order to solve the problem of the workability. The elevated deck 8 has a substantially horizontal upper surface.
0 is provided with an unwinding pedestal 81, and the front end side (unwinding side of the heat insulating sheet body 90 shown by the arrow Q) on each of a pair of substantially parallel support rail portions 82 forming the unwinding pedestal 81, A pair of block-shaped ribs 83 are provided, and both ends of the original roll 84 in use in the axial direction of the roll shaft 85 are respectively mounted between the ribs 83 so that the roll shaft 85 can be positioned. Has become.

A new original fabric roll 86 is placed on the rear side of the original fabric roll 84, and a spare is formed on the rear end side of the unwinding stand 81 on the elevated deck 80. The original roll 87 is placed. In addition, the roll shaft 85 is the original roll 84.
Core tube (see reference numeral 88 of the rear original roll 87 on the rear side), and both ends in the axial direction thereof are slightly projected in the same direction to the side end side of the original roll. ..

With such a structure, when the unwinding of the raw fabric roll 84 in use is completed, a new raw fabric roll 86 located immediately behind is rolled at both ends of the roll shaft 85 on the support rail portion 82. After moving it forward,
An operator slightly lifts both ends of the roll shaft 85 to attach the both ends between the ribs 83. After that, the roll shaft is inserted through the core tube 88 of the spare original roll 87, and both ends of the roll shaft are lifted by the workers and placed on the support rail portion 82 at the rear vacant position.

[0008]

However, in the above-mentioned configuration of the prior art, at least two workers are required particularly when the preliminary original roll 87 is lifted onto the support rail portion 82, and the novel original fabric is used. When the roll 86 is moved to attach both ends of the roll shaft 89 to the ribs 83, it is necessary for a plurality of workers to lift the ribs by the height H (for example, about 50 mm) of the ribs again, resulting in poor production efficiency. There is.

Furthermore, since the end of the roll shaft 85 is sandwiched between the block-shaped ribs 83 during the unwinding of the raw roll 84 in use, the rolling resistance is large. In particular, at the moment when the tip end side of the heat insulating sheet body 90 fed from the raw roll 84 is laminated between the pressure rolls on the steel plate which is a metal plate running, the fed heat insulating sheet body is moved to the raw roll side. There is a problem in that the portion to be pulled is subjected to the tension to be pulled back and the portion concerned becomes a defective product.

Further, since the roll shaft 85 is merely inserted through the core tube, for example, when the raw fabric roll 84 in use is rotated, it is moved in the axial direction and fed out in the sheet width direction of the heat insulating sheet body. There is a problem that the position of is shifted (see arrow N in FIG. 8).

The present invention has been made to solve the above-mentioned problems of the prior art. It is easy to mount the original roll on the roll mount, and the rotational resistance when the heat insulating sheet is unwound is small, and It is an object of the present invention to provide a stacking device that does not cause a positional deviation of the heat insulating sheet body in the sheet width direction.

[0012]

In order to achieve the above object, the invention of claim 1 comprises a raw roll formed by winding a heat insulating sheet on a core tube, and a roll shaft inserted through the core tube. And a roll mount having substantially horizontal rails, both ends of which are supported in the axial direction, and the heat insulating sheet is unwound from the original roll on the roll mount, and the wound heat insulating sheet is run. In a laminating device of a heat insulating sheet body and a metal plate configured to be laminated on a metal plate to
Lifting means for moving up and down the original roll to a predetermined height position, which is composed of a hydraulic mechanism or an electric mechanism, is provided near the roll mount.

According to a second aspect of the present invention, in the first aspect of the present invention, the rail portion is disposed substantially flush with the upper surface of the rail portion, and the roll shaft is disposed between at least two rotating disc-shaped bodies. It is characterized in that it is provided with a bearing portion supported by.

According to a third aspect of the invention, in the invention of the first or second aspect, the roll shaft has a step portion having a large diameter toward the central portion side of the axial length, and the step portion. Touches the inside of the rotating disk-shaped body.

[0015]

[Operation] When the unwinding of the original roll in use is completed,
The new original roll located immediately behind is moved forward so that both ends of the roll shaft roll on the support rails on the roll mount, and then the roll shaft is directly attached to the bearing formed of the rotary disk. Support both ends of. Then, the roll shaft is inserted through the core tube of the spare original roll, and the spare original roll on the roll mount is placed on the lift means lowered to the lowest position. The lift means is raised to a position where the roll shaft of the spare original roll is substantially level with the rail portion.
Then, the spare original roll is moved forward while rolling the roll shaft on the support rail. A step portion is formed at both ends in the axial direction of the roll shaft, and the end surface of the step portion abuts on the inner disk surface of the rotating disk-shaped body forming the bearing portion. Of the heat insulating sheet is restricted, and the movement of the heat insulating sheet body fed from the original roll in the sheet width direction is restricted.
