Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sticker or a sticker with an adhesive applied to a glass surface, a painted surface of an automobile, or the like.
Also, the present invention relates to a peeling disk such as a sticker which is used by being attached to a rotary driving tool such as a hand grinder in order to remove an adhesive or the like remaining after peeling an adherend adhered via a double-sided tape.

[0002]

2. Description of the Related Art Conventionally, a rotary roll for peeling an adhesive has been used to remove an adhesive seal or an adhesive bonded to a glass surface, a painted surface of an automobile, or the like.
No. 143.

[0003] In the peeling rotary roll, a contact surface of a roll-shaped main body pressed against a surface to be peeled is formed of rubber or synthetic resin having elasticity and abrasion resistance. By attaching to the apparatus and pressing the outer circular contact surface against the surface to be peeled while rotating, the adhesive on the surface to be peeled is softened by frictional heat and peeled. In addition, a method is employed in which the rotating roll is rotated at a low speed by artificially decelerating the rotation driving device, and the object to be peeled is peeled off relatively slowly.

[0004]

However, with the above-mentioned conventional rotating rolls, many workers are dissatisfied with the low-speed peeling operation, and there are those who use the rotating rolls more than the allowable rotation speed. As a result, excessive frictional heat is generated between the contact surface of the rotating roll and the object to be peeled, causing serious damage to the painted surface of the automobile, which is the base of the object to be peeled, and the high heat generated from the roll body. There was a problem that an unpleasant and harmful odor was generated, which could harm the health of workers. Therefore, the development of a disc for peeling an object to be peeled, which suppresses the generation of harmful frictional heat, satisfies the peeling operation of the object to be peeled, and has a high efficiency of the peeling operation, is currently desired by those skilled in the art.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the above-mentioned prior art rotary roller for peeling an adhesive, and according to claim 1, a disk made of a soft synthetic resin or rubber is provided. On the outer periphery of the main body, a plurality of plate-shaped projecting portions are radially projected at regular intervals in the circumferential direction, and a concave groove portion is provided between each of the plate-shaped projecting portions, so that each plate-shaped projecting portion is formed. When the tip of the protruding part is used by pressing against the object to be peeled, the temperature rise of the object to be peeled is limited by the effect of suppressing the generation of frictional heat and the heat radiation effect, and the tip of the plate-shaped projecting part with centrifugal force It is an object of the present invention to improve the peeling efficiency by the interaction between the striking force and the frictional force exerted on the object to be peeled by the part.

Further, according to the present invention, the plurality of plate-like projecting portions are divided into a plurality of layers in the thickness direction of the disk main body, so that the tips of the plurality of plate-like projecting portions are separated from each other. It is an object of the present invention to make it possible to efficiently come into contact with undulations, concave portions, groove portions, and the like so as to be efficiently peeled off.

According to the third aspect of the present invention, each plate-like projecting portion of each layer is opposed to a concave groove portion between each plate-like projecting portion of an adjacent layer. It is another object of the present invention to reduce the vibration generated when the contact surface intermittently comes into contact with the surface to be separated.

According to the fourth aspect, the tips of the adjacent plate-shaped projections are connected alternately on the side surfaces, so that the bases of the respective plate-shaped projections can be sufficiently prevented from being partially broken. It is an object of the present invention to achieve a high strength and avoid falling off.

[0009]

In order to achieve the above object, according to the present invention, a rotary shaft or a shaft hole for mounting to a rotary driving tool is provided at the center, so that abrasion and elasticity are reduced. By protruding a plurality of plate-shaped protrusions that press against the surface to be peeled at regular intervals in the circumferential direction on the outer periphery of a circular disk body made of soft synthetic resin or rubber having
A plurality of grooves for suppressing generation of frictional heat, radiating heat, and cooling are formed between the projecting portions.

According to a second aspect of the present invention, the plurality of plate-like projecting portions are divided into a plurality of layers by a plurality of slits provided at regular intervals in the width direction thereof. I do.

According to a third aspect of the present invention, each of the plate-shaped projecting portions of each of the divided layers is disposed so as to face a concave groove between the plate-like projecting portions of an adjacent layer. I do.

According to a fourth aspect of the present invention, the tips of the adjacent plate-shaped protruding portions are alternately connected by connecting plates on the side surfaces.

[0013]

According to the present invention, the peeling disc is rotated around the rotating shaft or the shaft hole by fixing the shaft to the rotating shaft or the chuck of the rotary driving tool with the shaft hole or the rotating shaft. The tip of the plate-like projection with the centrifugal force generated by the rotational movement by pressing the tip of the projecting part against the object to be peeled (sticker, seal, etc.) causes the repulsion between the beating force and the frictional force exerted on the object to be peeled. By the action, the object to be separated is separated into small pieces.

With respect to the object to be peeled once, fragments having an appropriate size fall off independently, and small fragments or adhesives are taken in by the abraded shavings at the tips of the respective plate-like projections. By dropping, it is removed from the surface to be peeled.

Since the contact surface of the plate-shaped projecting portion pressed against the object to be peeled is always kept fresh by the wear of the tip of the plate-shaped projecting portion, the frictional force provided for the peeling action is small. It will always be kept constant. Also, since small pieces such as stickers and stickers that have been peeled off do not re-attach to the contact surface at the tip of the plate-shaped protrusion, the small pieces do not rub against the painted surface of an automobile or the like. Will not hurt.

Since the tip of each plate-shaped protruding portion makes intermittent contact with the surface to be peeled, the contact time per one rotation of the disk is shorter than that of a circular rubber roll that makes continuous contact. In addition to the generation of frictional heat and the storage of the same heat on the surface to be peeled, there is basically little, and due to the abrasion property of the disc material, a part of the frictional energy is consumed for abrasion, and the corresponding frictional heat generation At the same time, the contact surface of the plate-shaped protruding portion, whose temperature has risen slightly, also becomes a shavings due to abrasion of a part thereof and falls off, so that the heat storage effect on the disk is also suppressed. In response to the increase in the pressing force, the elasticity of the disc material causes the plate-shaped protruding portion to warp rearward in the rotational direction, and the pressing force actually applied to the surface to be peeled is buffered, so that it becomes more positive. Suppresses the generation of frictional heat.

Further, the air existing in the concave grooves between the respective plate-shaped projecting portions repeatedly moves while being in contact with the surface to be peeled by the rotational movement of the disk. become. As a result, when the disc is used, the disc has an effect of suppressing the generation of a series of frictional heat and an effect of radiating and cooling the heat, so that the object to be peeled and the substrate thereof are heated to a temperature at which damage is caused. Therefore, the object to be peeled can be peeled without the restriction of using the rotary drive tool at a reduced speed.
