Description

Description Adhesive removal equipment Technical field

The present invention relates to an apparatus for removing and removing an adhesive substance efficiently attached to an automobile body or the like. Background art

Conventionally, a car body of an automobile is attached with a sticking force or various interior / exterior materials with an adhesive such as an adhesive.

These stitches and interior / exterior materials are hindered when repairing or repainting the car body, so they are peeled off or removed from the car body. There is a problem in that removing the objects manually requires a lot of time and labor, and the work rate is very poor.

In order to solve such a problem, for example, Japanese Utility Model Publication No. Hei 9-143 proposes a rotary roll for peeling an adhesive which peels off and removes a step force or the like attached to a vehicle body or the like. The pressure-sensitive adhesive peeling roll described in the above publication is configured such that a roll-shaped main body having elasticity and abrasion resistance on its surface is rotated by an electric grinder / air grinder and pressed against a surface to be peeled, so that the surface to be peeled is The adhesive is softened by frictional heat and peeled off. W

However, since the pressure-sensitive adhesive rotating roll disclosed in the above publication has a solid structure in which the roll-shaped main body is formed of rubber or synthetic resin, when the main body is pressed against the surface to be peeled, the friction between the main body and the surface to be peeled is reduced. As a result, the main body is worn and a large amount of wear powder is generated.

Since this abrasion powder is a fine powder, it scatters around as the roll-shaped main body rotates, thereby deteriorating the work environment, thereby causing a reduction in work efficiency. It enters the body through the eyes, nose, and mouth of the human body, causing problems such as impairing the health of workers.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide an apparatus for peeling and removing an adhesive substance in which fine abrasion powder does not fly around. Disclosure of the invention

The present invention provides an adhesive peeling / removing apparatus for peeling and removing an adhesive adhered to a vehicle body or the like, a mounting shaft mounted on a rotation driving means, a tape mounting member provided on the mounting shaft, and a tape mounting member. Since a peeling member consisting of an attached adhesive tape and pressure means for fixing the peeling member to the tape mounting member by pressing the tape mounting member in the axial direction were used, an electric drill or air By rotating the mounting shaft by means of a rotary drive such as a drill, the outer peripheral surface of the peeling member is pressed against the sticking force to be peeled off or the sticking material adhered to the vehicle body. The frictional heat is generated in between and softens the adhesive or sticky material with the adhesive force, and at the same time, the adhesive surface of the adhesive tape is combined with the adhesive or sticky material by frictional force, Since it can be peeled off from the body, it is possible to efficiently remove the sticking force sticking to the car body and the sticky substance adhered to the car body.

In addition, the peeling force and sticky substance are removed together with the scraps of the tape, and fall off, which is different from the conventional peeling method using a roller made of rubber or resin. It does not scatter, thereby deteriorating the work environment due to the deterioration of the work environment, and the scattered abrasion powder enters the body through the eyes, nose and mouth of the worker and impairs the health of the worker, etc. The conventional problem of the above can be solved.

Further, in the present invention, a pressing plate in which a pressing means is in contact with both end surfaces of the tape mounting member, and a screw portion formed on the mounting shaft are screwed, and the pressing plate is pressed in the axial direction of the tape mounting member. Since it is composed of a nut, the peeling member can be securely fixed to the tape mounting member simply by tightening the nut, so that the peeling member runs idle during work and the peeling work cannot be performed, and the work efficiency is reduced. There is no danger of lowering and the like, and the work of replacing the worn peeling member with a new peeling member can be easily performed in a short time.

Also, since a plurality of projections are protruded on the surface of the pressing plate that abuts against the end surface of the tape mounting member, the protrusions protruding from the pressing plate bite into the end surface of the tape mounting member when the pressing means is tightened. There is no slippage between the pressure plate and the tape mounting member, and a chamfered surface is formed at both corners of the tape mounting member, and a plurality of concave grooves are formed in the outer peripheral surface in the axial direction. From the above, the tape mounting member 3 is easily expanded in the radial direction when pressure is applied to the tape mounting member 3. Since the contact surface pressure between the outer peripheral surface of the tape attaching member and the inner peripheral surface of the core of the peeling member increases, the peeling member is less likely to come off from the tape attaching member, so that safety during operation is improved.

Further, according to the present invention, the tape attaching member is formed of two members having a tapered shape, and is attached to the attaching shaft such that the small-diameter portions face each other, and the core of the peeling member is held by the tapered surface of the tape attaching member. Since the peeling member can be attached to the tape attaching member even if the inner diameter of the core material changes, it is possible to cope with various peeling members having different inner diameters.

In addition, since a heat-resistant masking tape, cloth tape, or the like is used as the peeling member, the peeling member, which is a consumable product, can be obtained at low cost. BRIEF DESCRIPTION OF THE FIGURES

FIG. 4 is a cross-sectional view showing a modified example of the sticky substance removing apparatus of the present invention. FIG. 5 is an exploded perspective view showing a modified example of the sticky substance removing apparatus of the present invention. It is the same sectional view. BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the present invention will be described in detail with reference to the drawings.

The main body 1 of the adhesive removing apparatus shown in FIGS. 1 and 2 has a mounting shaft 2 and It comprises a cylindrical tape mounting member 3 made of an elastic body and provided on one end side of the mounting shaft 2 and means 4 for pressing the tape mounting member 3. A screw portion 2a is formed at one end of the mounting shaft 2, and the center of a tape mounting member 3 formed of rubber or synthetic resin into a cylindrical shape is fitted into the screw portion 2a. A pair of pressing plates 4 a formed by washers having substantially the same diameter as the outer diameter of the tape mounting member 3 are in contact with both end surfaces of the mounting member 3.

The pressurizing means 4a is composed of the pressing plate 4a and a pair of nuts 4b screwed to the screw portion 2a of the mounting shaft 2. By tightening the nuts 4b, a pair of pressing By pressing the end face of the tape mounting member 3 in the axial direction of the mounting shaft 2 by the means 4 ab, the outer peripheral surface of the tape mounting member 3 can be expanded in the radial direction.

The nut 4b should not be loosened during the work, or the screw 2a of the mounting shaft 2 should be screwed in the direction opposite to the direction of rotation of the rotating drive means, so that the nut 4b rotates with the rotation of the mounting shaft 2. May be tightened.

The peeling member 5 that peels off the sticking force adhered to the vehicle body and the adhesive remaining on the vehicle body after the interior and exterior materials are removed from the vehicle body are the cylindrical core 5a and the outside of the core 5a. It consists of an adhesive tape 5b wound around a roll.

The core 5a has an inner diameter slightly larger than the outer diameter of the tape mounting member 3 so that the tape mounting member 3 can be easily inserted into the core 5a, and the pressing means 4 When the outer peripheral surface of the mounting member 3 is expanded in the radial direction by pressing the tape mounting member 3 from the axial direction, the inner surface of the core 5a is attached with the tape. The peeling member 5 is in close contact with the outer peripheral surface of the tape attaching member 3 so that the peeling member 5 does not idle with respect to the tape attaching member 3 due to the frictional force between them.

For the adhesive tape 5b, masking tape used for baking paint on the vehicle body or an equivalent is used.

The masking tape is formed by applying a heat-resistant acryl-based adhesive to at least one side of a tape material made of Japanese paper to form an adhesive tape 5b so that it can withstand the high temperature during baking coating. It can withstand temperatures as high as 100 ° C or more.

In addition, the width of the ready-made masking tape is standardized to, for example, 6 mm, 15 mm, 24 mm, and 3 O mm, and the mounting member 3 for attaching the peeling member 5 in accordance with these standards. Lengths of approximately 6 mm, 15 mm, 24 mm, and 30 mm are prepared in advance.

Next, the operation of the above-structured adhesive removing apparatus will be described.

The sticking force and seal attached to the car body are firmly adhered to the car body with a synthetic resin adhesive so that they cannot be easily peeled off.The interior material attached inside the car body and the outside material attached to the car body Exterior materials such as moldings and side visors are firmly adhered to the vehicle body with a synthetic resin adhesive.

For this reason, it is not easy to peel off the sticking force or seal when repairing the car body, etc., and if you try to forcibly peel it, it may damage the car body and paint, and it will adhere to the car body. Even if the interior and exterior materials are removed, the adhesive remains on the vehicle body as an adhesive, so it is necessary to remove this adhesive, but the adhesive is already It cannot be easily removed because it has hardened.

To remove these sticky substances, first use a rotary drive that can be held by hand, such as an electric drill or air drill, and attach it to the chuck (not shown) of the rotary drive using the mounting shaft 2 of the main unit 1. Attach the stripping member 5 of the width selected according to the work to the tape mounting member 3 provided on the mounting shaft 2. At this time, the winding direction of the tape of the peeling member 5 is the rotation of the tape mounting member 3. Attach it in the opposite direction.

In other words, when the tape attaching member 3 rotates clockwise, the tape is wound so that the peeling direction of the tape of the peeling member 5 is leftward, and the friction applied to the outer peripheral surface of the peeling member 5 when the adhesive is peeled off. The adhesive tape 5b is tightened by force. Then, each nut 4b of the pressing means 4 is tightened up, and the tape attaching member 3 is pressed from the axial direction by the pressing plate 4a, thereby expanding the outer peripheral surface of the tape attaching member 3 in the radial direction. The peeling member 5 is firmly attached to the attaching member 3.

Next, in this state, the mounting shaft 2 is rotated by the rotation driving means, and the outer peripheral surface of the peeling member 5 is pressed against a sticking force to be peeled or an adhesive adhered to the vehicle body. Along with this, frictional heat is generated between the peeling member 5 and the stick force or the sticky substance, and the adhesive or sticky substance with the stick force is softened.

At the same time, the tape portion of the adhesive tape 5b becomes shavings due to frictional force and falls off from the adhesive tape 5b, and the remaining adhesive surface is combined with the softened adhesive or sticky material of the stepping force and peels off from the vehicle body. The peeling force and adhesive are removed with the scraps from the tape. Since both are agglomerated and fall off, unlike a conventional case of peeling off with a roller made of rubber or resin, fine abrasion powder does not scatter around.

As a result, the working environment is not degraded, and there is no concern that the worker's health is impaired because the worker does not have to worry about inhaling the wear powder.

The adhesive tape 5b wears out and the outer diameter decreases as the peeling force and the removal of the adhesive material progress, so when the adhesive tape 5b is almost exhausted, the operation is temporarily stopped and the adhesive tape 5b is removed. By replacing the new adhesive tape 5b with the new one, the work can be continued.Therefore, it is possible to efficiently remove and remove the sticking force applied to a wide area of the vehicle body and the adhesive substance remaining on a wide area of the vehicle body. become able to.

Then, when the adhesive force or the shavings of the adhesive tape remains on the vehicle body when the removing of the sticking force or the adhesive is completed, the waste cloth may be wiped with a volatile liquid such as silicon off.

If there is a concern that the nut 4b screwed to the tip of the mounting shaft 2 may damage the vehicle body due to the contents of the work, etc., the nut 4b may be peeled off as shown in the usage example shown in Fig. 3. The work may be performed by attaching the adhesive tape 5b to the tape attaching member 3 having a length shorter than the width of the adhesive tape 5b in advance so that the adhesive tape 5b does not protrude from the end face.

On the other hand, FIG. 4 shows a modified example of the tape attaching member 3. In this modified example, the tape attaching member 3 is formed of two tapered members 3a and 3b, and the small diameter side ends face each other. Thus, the taper surface 3c of each of the tape mounting members 3a and 3b supports the end of the core 5a of the peeling member 5. The method of removing the sticky substance by the sticky substance peeling device according to the modified example is the same as that of the above-described embodiment, and thus the description is omitted. However, by adjusting the interval between the tape mounting members 3a and 3b, the core material is adjusted. It is possible to cope with the peeling member 5 having a different inner diameter 5a. 5 and 6 show another modified example of the adhesive removing device. In this modified example, the adhesive member comes into contact with the inner surface of the pressing plate 4a of the pressing means 4, that is, the end surface of the tape attaching member 3. A plurality of projections 4c are provided on the surface so that these projections 4c bite into the end face of the tape attaching member 3 when the nut 4b is tightened.

Further, the corners of both end surfaces of the tape attaching member 3 are chamfered to form a chamfered surface 3d, and a plurality of concave grooves 3 are formed on the outer peripheral surface of the tape attaching member 3 in an axial direction parallel to the attaching shaft 2. e is formed at intervals in the circumferential direction.

The method of removing the adhesive using the adhesive removing device according to the modified example is the same as that of the above-described embodiment, and therefore the description is omitted.However, when the nut 4b of the pressurizing means 4 is tightened, the pressure plate 4a protrudes from the pressing plate 4a. Since the projections 4c provided cut into the end surface of the tape mounting member 3, no slippage occurs between the pressing plate 4a and the tape mounting member 3.

Further, by forming chamfered surfaces 3 d on both ends of the tape mounting member 3 and forming a plurality of concave grooves 3 e on the outer peripheral surface, when the tape mounting member 3 is pressed by the pressing means 4, Since the tape mounting member 3 easily expands in the radial direction, the contact surface pressure between the outer peripheral surface of the tape mounting member 3 and the inner peripheral surface of the core member 5 of the peeling member 5 increases, and the peeling member is separated from the tape mounting member 3. Since it is difficult to remove the tape, the safety at the time of work is improved, and when the nut 4b is loosened to replace the peeling member 5, the tape mounting member 3 instantaneously contracts to the original diameter, Work to replace peeling member 5 ,

10 can be performed efficiently in a short time.

Furthermore, the plurality of grooves 3 e formed in the outer peripheral surface of the tape mounting member 3 in the axial direction reduces the contact area between the outer peripheral surface of the tape mounting member 3 and the core 5 a of the peeling member 5, and air enters. Therefore, even if the peeling member 5 is set on the tape attaching member 3 for a long time, the peeling member 5 cannot be removed from the tape attaching member 3.

In the above-described embodiment and modified examples, the example in which the adhesive tape 5b made of paper tape is used as the peeling member 5, but if heat resistance is provided, cloth tape ゃ nonwoven fabric tape, resin tape, cork, leather, etc. May be used in the form of a tape. Industrial applicability

As described in detail above, the adhesive peeling and removing apparatus of the present invention includes a tape mounting member provided on a mounting shaft, a peeling member made of an adhesive tape, and a rotating shaft such as an electric drill or an air drill. While rotating the peeling member, the outer peripheral surface of the peeling member is pressed against the sticking force to be peeled off or the sticky substance adhered to the car body. The adhesive surface of the adhesive tape can be combined with the adhesive or adhesive material and peeled off from the vehicle body by softening the adhesive or the adhesive material with the frictional force at the same time. The peeled adhesive can be efficiently peeled off.

In addition, the peeling force and sticky material are separated together with the scraps of the tape and fall off, which is different from the conventional peeling method using a roller made of rubber or resin. The fine abrasion powder does not scatter around, deteriorating the work environment, and the scattered abrasion powder enters the body through the eyes, nose and mouth of the worker, and the health of the worker Can be solved.
