Description

  The present invention is suitably used in the field of building curing. In particular, the present invention relates to a jig that can make an adhesive tape sticking operation convenient for curing a design-like building member that has been subjected to uneven processing.

Conventionally, as the adhesive tape for curing used in the coating of buildings and the components constituting it, sealing for joints, etc., paper, cloth, resin film, non-woven fabric is generally used as the support. Yes. In recent years, many designable members whose surface has been processed into irregularities are used, and it is difficult for the curing tape to adhere to them. Due to poor adhesion to the uneven surface, there are current situations that cause problems such as tape dropping, deterioration of the finish due to penetration of the coating agent, and tearing of the support during peeling of the tape due to penetration of the coating agent.

Design irregularities are often found mainly on the outer walls of ordinary houses, and well-known paint surfaces such as lysine, stucco, skin, and ripples. Various design properties can be imparted by painting techniques such as brush, spray, roller, and iron coating. In addition, paints resembling natural stone such as ceramics, sandstone, and stone have recently been seen. Apart from these coating materials, siding boards, bricks, tiles, and the like are well known as wall materials to which pre-formed members are combined and attached at the construction site.

Efforts have been made to make the adhesive tape support thinner, more flexible, or increase the thickness of the adhesive layer in order to better follow the surface of such a design uneven member. There is a problem that it takes labor to get used and to bond. In order to improve the crimping workability to the uneven surface, the back of the curing tape is rubbed and pressed with a jig in the shape of bamboo bunches, but a support body with low impact resistance such as paper was used. In the case of a tape, there is a problem that the support is damaged and torn when it is peeled off, or the finish of the coating becomes poor.
Further, a pressure roller for pressure bonding an adhesive tape or the like is also known (Patent Document 1). Here, a pressure-bonding roller having a structure capable of removing remaining air by a needle-like member protruding from the outer peripheral surface of the roller when a pressure-bonding operation is performed is disclosed.

INDUSTRIAL APPLICABILITY The present invention is capable of efficiently pressure-bonding an adhesive tape even on a flat surface including an uneven surface, and is particularly suitable for use in affixing a building curing tape, and particularly a designable member that has been provided with an uneven shape. The purpose is to provide an adhesive tape crimping roller with a simple structure that can simplify the work of pressing by hand when applying tape to the tape and clean the finish of painting and sealing after curing. It is.

In the present invention, an elastic rubber layer is provided on the outer periphery of the pressing roller to immediately follow the curing tape to the uneven member, and the surface layer is processed into an uneven shape to dramatically improve the pressure bonding efficiency to the uneven member. I let you.
That is, the present invention relates to a core portion, a rotating body whose outer periphery is covered with an elastic body made of an elastic material, a rotating body support portion having a support shaft that supports the rotating body, and a grip connected to the support shaft. A pressure-sensitive adhesive tape pressing roller comprising a portion having a hardness of 5 to 70 as measured by a type A durometer based on JIS-K-6253, and the surface of the elastic body covered on the outer periphery of the rotating body is The pressure-sensitive adhesive tape pressing roller is characterized by having an uneven shape.
Further, in the present invention, grooves having a depth of 2 to 10 mm are provided at regular intervals of 1 to 5 mm in the rotational direction and the width direction of the outer periphery of the rotating body, and the area ratio of the land portion to the outer peripheral surface area is 10 to 90%. it can.
Furthermore, in the present invention, the outer diameter φ of the rotating body can be 30 to 60 mm, the width 20 to 50 mm, and the thickness of the elastic material coating layer 5 to 25 mm.
In the present invention, the elastic material coated on the outer periphery is selected from urethane, butadiene, styrene butadiene, chlorosulfonated polyethylene, acrylonitrile butadiene, hydrogenated styrene, ethylene vinyl acetate, natural rubber, and silicon rubber. Or it can be set as two or more types of rubber materials.
Furthermore, according to the present invention, the shape of the rotating body can be tapered.

The pressure roller of the present invention can be manufactured at a low cost with a simple structure, and by providing an elastic rubber layer on the outer periphery and further processing the outer peripheral surface into an uneven shape, without damaging the base material of the adhesive tape, The tape can quickly follow any uneven surface and can be crimped.

A typical example of the tape pressing roller of the present invention is shown in FIG.
The core portion 1 is hollow at the center, and the outer periphery of the core portion is covered with an elastic body 4 made of an elastic material, forming a rotating body in which the core portion 1 and the elastic body 4 are integrated, and supporting the rotating body. The rotating body support part 3 having the supporting shaft 2 and the gripping part 6 connected to the rotating body support part. The support shaft 2 is rotatable with respect to the rotating body support part 3. The support shaft 2 and the rotating body support 3 may be supported by a bearing or the like.
The outer peripheral surface 5 of the elastic body forms an uneven shape.
Here, examples of the elastic material used for the outer periphery of the tape pressing roller of the present invention include a rubber material, a sponge material, and a composite material. The hardness of the elastic material is measured by a type A durometer based on JIS-K-6253. A value in the range of 5 to 70, preferably 30 to 50 is suitable. If the hardness is too low, wear deterioration becomes remarkable, and if the hardness is too high, the effect of following unevenness declines. When the surface of the elastic body is flat, it is possible to follow the uneven surface to some extent by reducing the hardness, but there is a limit to the followability when the surface of the member is severely undulated. Therefore, by making the surface shape of the outer periphery of the elastic body into a concavo-convex shape, it becomes possible to press into the recessed portion that has entered deeply, and the followability of the tape is dramatically improved.

The size of the pressure roller is preferably a size that can be grasped lightly with one hand, and a roller having a size in which the outer diameter φ of the rotating body is 30 to 60 mm, the width is 20 to 50 mm, and the thickness of the elastic material coating layer is 5 to 25 mm. Assuming the uneven undulation situation of the outer wall material that is widely marketed, grooves with a depth of 2 to 10 mm are provided at regular intervals of 1 to 5 mm in the longitudinal direction and the width direction of the roller outer periphery, and the area ratio of the land portion to the outer peripheral surface area is Those in the range of 10 to 90% are suitable. If the concave and convex size provided on the outer peripheral surface of the rotating body is too small and the groove is too deep, the repulsive force of the rubber is lost, the concave and convex size is too large, and if the groove is too shallow or the land density is too small, the depression in the recess is insufficient. Become. Therefore, it is necessary to adjust the hardness of the elastic body according to the uneven size and the depth of the groove. However, it is preferable to set the hardness high if the uneven size is small and the groove is deep, and low if the size is large and the groove is shallow. .
FIG. 2 shows a sectional view of the concavo-convex shape.
7 represents the groove interval, 8 represents the land portion, and 9 represents the depth of the groove.

The elastic material used in the present invention is a natural rubber known as a general rubber material, synthetic isoprene, styrene-isoprene copolymer, styrene-butadiene copolymer, ethylene-vinyl acetate copolymer, acrylic acid. Examples include ester copolymers, chlorosulfonated polyethylene, organopolysiloxane series, urethane series, ethylene propylene series, polyether series, and hydrogenated styrene series. In order to satisfy the application of the present invention, the material having high wear resistance is selected from urethane, butadiene, styrene butadiene, chlorosulfonated polyethylene, acrylonitrile butadiene, hydrogenated styrene, ethylene vinyl acetate, natural rubber, and silicon rubber. One or two types of mixed rubber materials are particularly preferable. Assuming that many cases are used outdoors, a material having higher light stability is preferable. Further, if necessary, a coloring pigment, an ultraviolet absorber, an anti-aging agent, a plasticizer, and the like can be appropriately contained within a range not impairing the effects of the present invention. Carbon black, inorganic colloidal silica, fillers such as clay, talc, and calcium carbonate, surface treated products, and the like can be appropriately used for the purpose of reinforcing the elastic material, improving grip properties, and increasing the amount. The rubber agent may be foamed as long as the wear resistance is not affected.

In the actual construction site, when a tape is applied to the corner of the entrance, there is a problem that the hand gripping the roller hits the wall side and the force is difficult to enter and the workability is deteriorated. In this case, the roller can be tapered so that it can be crimped to the corner. Therefore, it is necessary to select the shape of the roller according to the situation at the site, and the roller portion may be configured to be removable.
FIG. 4 shows a schematic diagram of the corner-only roller in FIG. 3.
