Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive for cleaning the surface of a member by adhering and removing dirt and dust adhering to the surface of various members such as cloth, paper, plastic material, glass, and metal plate. The present invention relates to a roll, and more particularly to an antistatic dust removal adhesive roll for removing static electricity generated during removal through a human body.

[0002]

2. Description of the Related Art A pressure-sensitive adhesive roll is a roll formed by winding a pressure-sensitive adhesive sheet in multiple layers, while rolling the roll in contact with a floor or a wall surface to adsorb and remove dirt and dust adhering to these surfaces. . Also, unlike a vacuum cleaner that exhausts at the same time as suctioning, the adhesive roll can remove dust and the like without causing dust and the like to fly up in the room, so that semiconductor production lines that dislike dust and the like can be removed. Widely used for cleaning clean rooms.

[0003]

Since the adhesive roll requires a support shaft for supporting the adhesive roll and a gripping member for operation, friction occurs between the roll of the adhesive roll and the support shaft, and static electricity is generated. As long as the static electricity does not flow out from the gripping member side, the static electricity accumulates on the adhesive roll side. The accumulated static electricity causes a spark discharge toward the electronic device in the clean room, which easily causes problems such as a drop in the power of the electronic device and a change in the conditions set in the electronic device.
On the other hand, when the adhesive roll and the support shaft are charged, dirt and dust are attracted to and adhere to them, but the attached dirt and dust easily fall off when the adhesive sheet of the adhesive roll is replaced, and the fallen dirt. There is a problem that dust and dust fly to the electronic device side.

[0004] There are various types of adhesive rolls in consideration of antistatic properties, for example, see, for example, JP-A-7-2412.
No. 69 and JP-A-8-24207. Japanese Unexamined Patent Publication No. 7-241269 discloses an "adhesive neutralizing dust removing roll and a ground electrode material", in which conductive fibers are juxtaposed at a position where a slight gap is provided from the outer periphery of the roll body, and the conductive fibers and the roll body are disposed. Is connected to the ground to prevent charging of the roll body. This allows
Adhesion of dust and dirt is removed and static electricity of the roll body is prevented from being charged. However, since the pressure-sensitive adhesive roll is formed by winding the pressure-sensitive adhesive sheet in multiple layers, the distance between the outer periphery of the roll body and the conductive fibers increases as the pressure-sensitive adhesive sheet is peeled off, and the static electricity removing effect is reduced. There is a problem.

On the other hand, the "adhesive roller" disclosed in Japanese Patent Application Laid-Open No. H8-24207 has a structure in which a supporting portion for supporting a roller portion and a handle connected to the supporting portion are electrically connected and the handle is connected to the ground. With this structure, the static electricity generated between the roller portion and the support portion is grounded, but there is no means for removing the static electricity on the surface of the roller portion, and the above-described problem occurs.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, so that static electricity is not charged to each part of the adhesive roll, dust and dirt are not charged, and troubles do not occur in electronic equipment.

The conductive pressure-sensitive adhesive roll 2 is formed of a cylindrical body as shown in FIGS. 1 and 2, and is formed by winding a pressure-sensitive adhesive sheet in multiple layers. Therefore, the conductive adhesive roll is shown in FIGS.
As shown in (2), the pressure-sensitive adhesive sheet to which dirt, dust, and the like are adhered is peeled off, and the outer diameter is gradually reduced to a small diameter. The conductive pressure-sensitive adhesive roll 2 is made of a pressure-sensitive resin composition using a rubber compound mainly composed of butyl rubber having adhesion and conductivity.

As shown in FIGS. 1 and 2, the support shaft 3 is formed of a rod bent in a U-shape, and one end of the support shaft 3 becomes a central axis of the conductive adhesive roll 2 to pivotally support the conductive adhesive roll 2. I do. Further, the other end side is a cylindrical body 1 of a handle member 7 described later.
4 is fixed to the outer periphery. Note that the support shaft 3 is formed from a conductive material such as stainless steel.

As shown in FIGS. 1, 2, 8, 9, etc., the conductive fiber 4 is disposed so as to cover substantially the upper half of the outer periphery of the conductive adhesive roll 2. It is arranged with a slight gap. The conductive fibers 4 are made of, for example, carbon fibers arranged in multiple layers.

The ground electrode material 5 is shown in FIGS. 1, 2, 8, and 9.
As shown in FIG. 3, the conductive adhesive roll 2 is fixed to the base end of the conductive fiber 4 and covers the outer periphery of the conductive adhesive roll 2 together with the conductive fiber 4.

In this embodiment, the moving shaft 6 includes a receiving shaft 9, a presser shaft 10, and a spring 11 which is one of urging means provided between both shafts, as shown in FIG. Become. Bearing shaft 9
Is disposed with the lower end thereof connected to the ground electrode material 5.
6 and 7, the receiving shaft 9 and the holding shaft 10
Is formed by enclosing a resin material 12 with an earth material 13 made of stainless steel or the like. The handle member 7 includes a cylindrical body 14 and a lever 15 in the present embodiment. The moving shaft 6 is housed in the cylindrical body 14 as shown in FIG.
Further, as shown in FIG. 3 and the like, the lever 15 is fixed to the holding shaft 10, and is made of, for example, a conductive material such as stainless steel. The cylindrical body 14 is also made of a conductive material.
A groove 16 is formed as shown in FIG. This groove 1
Reference numeral 6 denotes a vertical groove 16a for guiding the lever 15 along the axial direction of the cylindrical body 14, and a bent groove 16b which is bent in an L-shape from the vertical groove 16a. When the antistatic dust removing adhesive roll 1 is used, the lever 15 is pushed down along the vertical groove 16a and held in a state of being engaged with the bending groove 16b. That is,
In use, the lever 15 is engaged with the bending groove 16b and locked. Since the lever 15 is fixed to the holding shaft 10 as described above, when the lever 15 is engaged with the bending groove 16b, the spring 11 is pressed, and this pressing force acts on the receiving shaft 9.
Since the receiving shaft 9 is connected to the ground electrode material 5, this pressing force acts on the ground electrode material 5 and is transmitted to the conductive fiber 4 fixed to the ground electrode material 5. As shown in FIGS. 4 and 5, a copper plate 17 is fixed to the lever 15,
The copper plate 18 is also fixed inside the cylindrical body 14. As shown in FIG. 5, the copper plates 17 and 18 are arranged so that they come into contact with each other in a state where the lever 15 is fixed at the lock position. Therefore, in this state, the lever 15 and the tubular body 14 conduct electricity.

As shown in FIGS. 8 and 9, the conductive rubber tire 8 is made of, for example, a rubber material to which metal powder or the like is added and mixed. It consists of a shape member. The conductive rubber tire 8 is pivotally supported by a frame 19, and the frame 19 is fixed to the ground electrode material 5 on the base end side. With the above structure, the conductive rubber tire 8 communicates with the ground electrode material 5. Further, as described above, since the ground electrode material 5 is pressed by the spring 11 of the moving shaft 6, the conductive rubber tire 8 always contacts the outer periphery of the conductive adhesive roller 2.

Next, the static elimination action of the antistatic dust removing adhesive roll 1 of the present invention will be described. By rolling the antistatic dust removing adhesive roll 1 along the surface of the floor or wall, dust or dust adheres to the surface of the antistatic dust removing adhesive roll 1 and the floor or wall is cleaned. With this rolling operation, static electricity is generated on the outer peripheral surface of the conductive pressure-sensitive adhesive roll 2 and the contact surface between the conductive pressure-sensitive adhesive roll 2 and the support shaft 3. First, the static electricity generated on the surface of the conductive pressure-sensitive adhesive roll 2 ionizes air and is transmitted to the conductive fiber 4 disposed near the conductive pressure-sensitive adhesive roll 2, and then transmitted to the ground electrode material 5. A receiving shaft 10 is connected to the earth electrode material 5, and the receiving shaft 10 is
1 and connected to the presser shaft 9. On the other hand, since the lever 15 is connected to the presser shaft 9, the above-mentioned static electricity is discharged from the lever 1.
5 and flows out through the human body holding the lever 15. Therefore, static electricity generated on the outer peripheral surface of the conductive adhesive roll 2 is eliminated.

On the other hand, a conductive rubber tire 8 comes into contact with the outer peripheral surface of the conductive adhesive roll 2, and the conductive rubber tire 8 is connected to the ground electrode material 5 via a frame 19. Therefore, static electricity generated on the outer peripheral surface of the conductive adhesive roll 2 is also eliminated by the conductive rubber tire 8. Therefore, static electricity of the conductive adhesive roll 2 is reliably eliminated.

Further, static electricity generated between the conductive adhesive roll 2 and the support shaft 3 is transferred from the conductive support shaft 3 to the handle member 7.
To the cylindrical body 14. The tubular body 14 may be directly grasped by a human body, and is transmitted directly from the tubular body 14 to the human body to eliminate static electricity. Further, since the cylindrical body 14 is electrically connected to the lever 15 at the lock position by the copper plates 18 and 17, the cylindrical body 14 flows toward the human body via the lever 15 and is discharged. As described above, static electricity between the conductive adhesive roll 2 and the support shaft is also reliably eliminated.

As described above, the outer circumference of the conductive pressure-sensitive adhesive roll 2 is reduced in diameter by continuing use. 10 and 11
Shows the conductive adhesive roll 2 in that state. When the lever 15 is in the lock position, the spring 11 presses the receiving shaft 10 toward the ground electrode material 5. Therefore, even if the diameter of the conductive adhesive roll 2 is reduced, the pressing force of the receiving shaft 10 causes the ground electrode material 5 and the conductive fiber 4 to be applied to the conductive adhesive roll 2.
Side, and the conductive rubber tire 8 is always in contact with the conductive adhesive roll 2. Therefore, the gap between the outer periphery of the conductive pressure-sensitive adhesive roll 2 and the conductive fiber 4 is kept constant regardless of the diameter of the conductive pressure-sensitive adhesive roll 2. As described above, even if the pressure-sensitive adhesive sheet of the conductive pressure-sensitive adhesive roll 2 is almost exhausted, static electricity is removed, and spark discharge during cleaning can be prevented.
