Description

The present invention relates to a laminating device and a method of laminating building materials using the same.

Conventionally, when laminating interior materials and exterior materials used for building materials and infrastructure equipment, a technique of applying a liquid adhesive between the adherend and the interior materials and exterior materials and adhering them has been used. Such liquid adhesives include, for example, a one-component adhesive whose reaction is started by moisture in the air and a two-component adhesive whose reaction is started by mixing a main agent and a curing agent.

On the other hand, when a liquid adhesive is used, there is a problem that liquid drips, a problem that it is difficult to apply uniformly, and a problem that the thickness becomes uneven after bonding due to variations in coating pressure. .. Further, when a two-component adhesive is used, there is a problem that it is necessary to mix the main agent and the curing agent, which is troublesome for the user. Therefore, instead of the liquid adhesive, a technique using double-sided tape has been proposed, for example, as in Patent Documents 1 and 2.

Hereinafter, the laminating apparatus of the present invention will be described.

1. 1. First Pressing Part The first pressing part in the present invention is a member capable of attaching the first tape to the adherend.

The first pressing portion in the present invention is a member that attaches the unwound first tape to the adherend. Therefore, the first pressing portion is preferably a member that presses the first tape to the extent that it sufficiently adheres to the adherend. Here, the degree to which the first tape sufficiently adheres to the adherend is, for example, the degree to which air or the like does not enter between the first tape and the adherend and the first tape is not cut. It is not defined by a specific pressure or the like because it is appropriately adjusted according to the type of the first tape and the adherend.

The first pressing portion in the present invention has a shape to which the first tape can be attached, and examples of the shape include a roll shape and a spatula shape. In the present invention, the roll shape is preferable as shown in FIGS. 1 and 2. When the first pressing portion has a roll shape, the rotation of the first pressing portion causes the first tape to be attached to the adherend. Since the first pressing portion is not normally interlocked with other members, the rotation of the first pressing portion is not controlled by other members or the like and operates independently.

When the first pressing portion in the present invention has a roll shape, it is preferable that a predetermined friction occurs on the contact surface between the first pressing portion and the first tape. Here, the first pressing portion and the contact surface with the first tape, for example, points to the space R _m surrounded by a dotted line in FIG. 4, the first tape 1a is first separator 1a "and the first When it has the adhesive layer 1a', it refers to the contact surface between the first pressing portion 2a and the first separator 1a ". In the present invention, a predetermined friction is generated on the contact surface between the first pressing portion and the first separator, so that the first separator can be easily peeled off from the first adhesive layer.

As a method of generating friction on the contact surface between the first pressing portion and the first separator, for example, a predetermined material is formed on the surface of the first pressing portion, that is, the surface of the first pressing portion that comes into contact with the first separator. There is a method using. As the material used for the surface of the first pressing portion, for example, an inorganic material such as coated diamond or coated CBN (cubic boron nitride) is suitable. Further, as another material used for the surface of the first pressing portion, for example, a material in which particles are dispersed and embedded in a resin material can be mentioned. As the resin material, for example, urethane rubber, nitrile rubber, chloroprene rubber, ethylene rubber, propylene rubber, silicone rubber, butyl rubber, styrene rubber, hyperon rubber, fluororubber and the like can be used. Further, for the particles, for example, copper, nickel, silver, titanium, white alumina, crushed alumina, pink alumina, green silicon carbide, black silicon carbide and the like can be used.

The size of the first pressing portion can be appropriately adjusted according to the width of the first tape used and the like, and is not particularly limited. The first pressing portion in the present invention preferably has a size such that the first tape can be satisfactorily attached to the adherend by the first pressing portion.

2. 2. Second Pressing Part The second pressing part in the present invention is a member capable of attaching the second tape to the surface of the first tape attached to the adherend.

The second pressing portion in the present invention is a member for sticking the unwound second tape so as to be overlapped with the above-mentioned first tape. Therefore, the second pressing portion is preferably a member that presses the second tape to such an extent that it sufficiently adheres to the first tape. Here, the degree to which the second tape sufficiently adheres to the first tape means that, for example, air or the like does not enter between the first tape and the second tape, and the second tape is cut. It is not defined by a specific pressure or the like because it is appropriately adjusted according to the type of the second tape and the type of the first tape.

The second pressing portion in the present invention has a shape to which a second tape can be attached, and examples of the shape include a roll shape and a spatula shape. In the present invention, the roll shape is preferable as shown in FIGS. 1 to 4. When the second pressing portion has a roll shape, the rotation of the second pressing portion causes the second tape to be attached to the adherend. Since the second pressing portion is not interlocked with other members, the rotation of the second pressing portion is not controlled by the other members or the like and operates independently.

In the present invention, the second tape is attached so as to overlap with the first tape by the second pressing portion. Therefore, in the second pressing portion, when the laminating device is moved along the surface of the adherend, the second tape is superposed on the first tape attached by the first pressing portion. It is preferably arranged in. Here, "superimposing" means that when the laminating device of the present invention is moved along the surface of the adherend and the first tape and the second tape are attached, the second tape is attached. It refers to overlapping in a part of the area of the first tape, or overlapping so as to cover the entire area of the first tape. In the present invention, the latter is preferable. This is because the first tape can be overlapped with the second tape in a wider area. The overlap of the first tape and the second tape can be confirmed, for example, by observing from the Y direction of FIG.

It should be noted that when the laminating device is moved along the surface of the adherend, the second tape is arranged so as to be superposed on the first tape attached by the first pressing portion. In other words, when the stacking device is moved along the surface of the adherend, the first tape is attached by the first pressing portion and the second tape is attached by the second pressing portion. The direction of attachment is the same, and it means that the first pressing portion and the second pressing portion are arranged along the direction in which the first tape and the second tape are attached.

Here, the fact that the first tape and the second tape are arranged along the direction in which the first tape is attached means that, for example, the first pressing portion 2a and the second pressing portion 2b shown in FIG. 4 are observed from the Y direction. At that time, as shown in FIG. 5, it means that the first pressing portion 2a and the second pressing portion 2b are arranged along the traveling direction indicated by the arrow. In FIG. 5, the width _{W 2a} of the first pressing portion 2a, a width _{W 2b} of the second pressing portion 2b are the same, the first pressing portion 2a and the second pressing portion 2b, along the traveling direction This is an example in which they are all arranged so as to overlap.

Since the other explanations for the second pressing portion can be the same as those described in the above-mentioned "1. First pressing portion", the description here is omitted.

3. 3. First mounting portion and second mounting portion In the present invention, the first mounting portion capable of holding the wound first tape and unwinding the first tape to the first pressing portion. It is preferable that the second pressing portion holds the wound second tape and has a second mounting portion capable of unwinding the second tape.

Both the first mounting portion and the second mounting portion are members capable of holding the first tape or the second tape, and the first mounting portion further transfers the first tape to the first pressing portion. The second mounting portion can unwind the second tape to the second pressing portion.

The first mounting portion and the second mounting portion in the present invention are preferably in a roll shape, for example, as in the first mounting portion 4a and the second mounting portion 4b shown in FIG. This is because the first tape and the second tape can be unwound satisfactorily.

When the first mounting portion and the second mounting portion are in a roll shape, the first mounting portion and the second mounting portion preferably have gears as shown in FIG. The laminating apparatus of the present invention has a first winding portion for winding the first separator and a second winding portion for winding the second separator, and also has a first winding portion and a second winding portion. When the portion has a gear, the gear of the first mounting portion rotates the gear of the first winding portion, and the gear of the second mounting portion rotates the gear of the second winding portion, the following For such a reason, it is possible to satisfactorily attach the first tape and the second tape. That is, the first tape wound in a roll shape is held by the first mounting portion so that the gear and the shaft center in the first mounting portion are the same, and the gear and the shaft center in the second mounting portion are held. By holding the second tape wound in a roll shape on the second attachment portion so as to be the same, the first tape and the second tape are wound from the first attachment portion and the second attachment portion. Unwinding and winding of the first separator and the second separator by the first winding portion and the second winding portion can be performed in conjunction with each other. For this reason, it is possible to satisfactorily attach the first tape and the second tape. The winding of the first separator and the second separator here is a roll held so that the axis is the same as the gear of the first winding portion, and the gear and shaft of the second winding portion. It can be done by a roll held so that the minds are the same.

When the first mounting portion and the second mounting portion are in a roll shape and the first mounting portion and the second mounting portion have gears as described above, the axes of the gears in the first mounting portion are the same. As described above, the first tape wound in a roll shape is held by the first mounting portion, and the second tape wound in a roll shape is wound so that the gear and the axis in the second mounting portion are the same. When the tape is held by the second mounting portion, the size of the gears of the first mounting portion and the second mounting portion, specifically, the radius of the gears of the first mounting portion and the second mounting portion is the first. It can be appropriately adjusted according to the unwinding amount of the first tape and the second tape. For example, when the laminating device of the present invention has a first winding portion and a second winding portion, the unwinding amount of the first tape and the second tape and the first separator and the second separator It is preferable that the winding amount is always constant. Therefore, when the laminating device of the present invention has a first winding portion and a second winding portion, the radius of the first mounting portion and the second mounting portion is the gear and the first winding portion of the first winding portion. 2 It is preferable to adjust appropriately according to the radius of the gear included in the winding portion. When the radius of the gear of the first winding part and the radius of the gear of the second winding part are larger than the radius of the gear of the first mounting part and the radius of the gear of the second mounting part, the first The sticking of the tape and the second tape becomes lighter, and the operation of the laminating device can be lightened.

A first winding portion and a second winding portion capable of winding the second separator from the second tape attached to the surface of the first tape by the second pressing portion. It is preferable to have.

The first winding portion and the second winding portion in the present invention have gears like the first winding portion 3a and the second winding portion 3b shown in FIG. 1, and have the same axis as the gear. It is preferable that the roll is held so as to be. Since it can be synchronized with the first mounting portion and the second mounting portion, the unwinding of the first tape and the second tape and the winding of the first separator and the second separator are interlocked with each other, and the first This is because the tape and the second tape can be satisfactorily laminated.

When the first take-up part and the second take-up part have gears and the roll is held so that the axis is the same as the gears, the gears of the first take-up part and the second take-up part have. The size of the gear, specifically the radius of the gears of the first and second take-ups, is the first separator and the first separator that is taken up by the roll held so that the axis is the same as the gear. It can be appropriately adjusted according to the winding amount of the second separator. For example, in the laminating apparatus of the present invention, it is preferable that the unwinding amount of the first tape and the second tape and the winding amount of the first separator and the second separator are always constant. Therefore, it is preferable that the radii of the gears of the first take-up portion and the second take-up portion in the laminating apparatus of the present invention are appropriately adjusted according to the radii of the gears of the first attachment portion and the second attachment portion. .. If the radius of the gears of the first winding part and the second winding part is larger than the radius of the gears of the first mounting part and the second mounting part, the first tape and the second tape will be attached. It becomes lighter, and the operation of the laminating device can be lightened.
