Abstract

PURPOSE:To attach quickly and surely a heat exchanging pipe to a mounting plate in the stage of fixing the zigzag heat exchanging pipe on the mounting plate by means of an adhesive sheet consisting of Al foil by using a device having cutting blades for the Al foil and a pressing member. CONSTITUTION:A back plate 2 for attaching a condensing pipe 1 is placed on a support 4 in the stage of attaching a condensing pipe as a zigzag heat exchanging pipe on the rear of a refrigerator. A zigzag pipe 1 as a condensing pipe for heat exchanging is placed thereon and further Al foil 3 with the surface coated thereon with an adhesive agent faced downward is placed thereon. A base body 5 provided with many cutters 7 conforming to the space between the pipe 1 and having a pressing member 6 consisting of a cushion material is lowered in this state. After the cutters 7 cut the foil 3 by conforming with the space between pipe 1, the cutters are retracted into the recesses 9 in the body 5 and the pipe 1 and the foil 3 are pressed by the member 6 to fix the pipe 1 by the foil 3 to the plate 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a heat exchange pipe mounting device in which a meandering heat exchange pipe is fixed to a mounting plate (1) using an adhesive sheet.

[Technical background of the invention]

Conventionally, for example, when installing and fixing a condensation pipe, which is a heat exchange pipe that forms a meandering shape on the inner surface of a back plate that is a mounting plate of a refrigerator, the condensation pipe was placed on the back plate and an adhesive was applied to the back surface. With the aluminum foil as an adhesive sheet placed almost entirely on the condensing pipe, the aluminum foil is manually cut between each pipe section of the condensing pipe with a cutter, and a presser is fitted between each pipe. The aluminum foil was pressed and bonded from the condensation pipe to the back plate using a jig.

[Problems with background technology]

However, with the conventional method described in (H), the aluminum foil must be cut at each meandering interval of the condensing pipe, and the aluminum foil must also be subsequently bonded at each meandering pitch. There is a problem in that it takes a lot of time to install the condensing pipe, and if there are variations in the meandering pitch of the condensing pipe, there is a risk that the above-mentioned presser jig may not be able to reliably press the aluminum foil onto the condensing pipe and the back plate. There was also a concern that the adhesion would be unreliable.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and an object thereof is to provide a heat exchange pipe attachment device that can quickly and reliably attach a heat exchange pipe to a mounting plate.

[Summary of the invention]

The present invention provides a support for supporting a mounting plate, a heat exchange pipe, and an adhesive sheet, and a base provided so as to descend and rise with respect to the support, and a cushioning material provided on the support side of the base. a pressing member that is provided on the base body so as to be retractable through the pressing member at substantially the same pitch as the meandering interval of the heat exchange pipe, and normally protruded from the pressing member by an elastic body; The present invention is characterized in that it is equipped with a cutter, thereby making it possible to cut and bond the adhesive sheet in one step.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

First, Fig. 1 shows a condensing pipe for a refrigerator as a heat exchange pipe. A back plate 2 as a mounting plate and an aluminum foil 3 as an adhesive sheet are shown, and the condensing pipe 1 is formed in a meandering shape with a predetermined meandering pitch P. is coated with adhesive. Now, FIG. 2 shows the entire installation device for the condensing pipe 1. back plate 2
and aluminum foil 6. In FIG. 2, reference numeral 4 denotes a support whose upper surface is flat. Reference numeral 5 denotes a base body, which is provided above the support body 4 so as to be lowered and raised by a lifting device (not shown) relative to the support body 4. 6 is a pressing member made of cushioning material;
This is attached to the support 4 side of the base body 5. Reference numeral 7 denotes a cutter, which is provided so as to be able to protrude and retract from the base body 5 through a pressing member 6, and which cuts, for example, 6 cutters at approximately the same pitch as the meandering interval P'+ (see FIG. 1) of the condensing pipe 2. It is located. Reference numeral 8 denotes a spring, which is an elastic body, and is disposed in a recess 9 formed in the base body 5, so that the cutter 7 is normally projected from the pressing member 6 by the spring 8.

Next, the case where the condensing pipe 1 is attached and fixed to the back plate 2 will be described. First, the back plate 2 is placed on the support 4, and the condensing pipe 1 is placed on the back plate 2, and the condensing pipe 1 is placed on the condensing pipe 1 as shown at two points e3X +M in FIG. Place the aluminum foil 3 on the pipe 1 so that it covers almost the entire pipe 1 with its adhesive surface facing downward (see Fig. 2). In this case, the sections between each pipe section (meandering interval section) of the condensing pipe 1 are located below the cutter 7. Then this second
The base body 5 is lowered toward the support body 4 from the state shown in the figure. Then, as shown in FIG. 3, the aluminum foil 3 is cut between the pipe parts of the condensation pipe 1 by the cutter 7, and from above the aluminum foil 3, as shown in FIG. 4, condenses with elastic deformation. By pressing the pipe 1 and pressing the back plate 2, the aluminum foil 3 is adhered from the outer peripheral surface of each pipe part of the nuclear condensation pipe 1 to the back plate 2, as shown in FIG. A condensing pipe 1 is attached to the back plate 2 by means of a foil 5.

Note that when transitioning from the state shown in FIG. 3 to the state shown in FIG. 4, the tip of the cutter 7 hits the back plate 2, but as the base 5 descends, the cutter 7 relatively enters the recess 9 side of the base 5. Pressing by the pressing member 6 can be performed without any problem.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings; for example, the attachment of the condensing pipe 1 to the back plate 2 of a refrigerator is not limited to being fixed, and the attachment plate may have a meandering shape for heat exchange. It can be applied to anything used when installing or fixing pipes, and the adhesive sheet can be pulled even if it is made of something other than aluminum foil 3, and the elastic body that biases the cutter 7 can also be made of something other than spring 8. It may be implemented with appropriate changes within the scope without departing from the gist.

〔Effect of the invention〕

As explained above, the present invention enables cutting and gluing of the adhesive sheet for attaching and fixing the meandering heat exchange pipe to the mounting plate in one step. Unlike the conventional method of cutting and gluing each piece using a holding jig, it is possible to quickly attach the heat exchange pipe to the mounting plate.Furthermore, since the pressing member is made of cushioning material, the heat exchange pipe can be easily attached to the mounting plate. Even if there is slight variation in meandering pitch, the adhesive sheet can be reliably bonded from the heat exchange pipe to the mounting plate due to the elastic deformation of the pressing member according to the heat exchange speed, and there is no risk of tearing the adhesive sheet. 6. Automatic mechanization of work, etc. can be eliminated. We can provide a heat exchange pipe installation device that has many excellent effects such as
