Abstract

PROBLEM TO BE SOLVED: To enable a static electricity to be discharged, dispensing with a separate member by employing a rubber with a discharging action at least, on one of rubber rolls for allowing a wall paper to pass through a predetermined passageway between the rolls arranged at an upper and a lower position. SOLUTION: A measuring roll 1 and a feed roll 2 are coated with a discharging rubber. This discharging rubber is internally mixed with an appropriate rate of fiber 4 generating a corona discharge. Consequently, if a static electricity is generated on the measuring roll 1 and the feed roll 2 by a friction between these rolls and a wall paper 3, a counter charge is induced at the tip of the fiber 4 in the rubber using the energy of the generated static electricity. Further, the counter charge is collected to the tip of the fiber 4 and is transferred to the static electricity from the tip to generate a neutralization phenomenon. This phenomenon leads to the linkage of a positive and a negative charge and their subsequent neutralization, so that the static electricity is completely removed. Thus it is possible to prevent an electric spark or a faulty operation from occurring without grounding or the use of extra spare parts.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper sizing machine. More specifically, the present invention relates to a wallpaper gluing machine, which effectively eliminates static electricity generated when a cloth such as wallpaper is disentangled from an original fabric of a roll, friction caused by a stay or a roll on the way, and the like. Is.

[0002]

2. Description of the Related Art Conventionally, various proposals have been made for wallpaper sizing machines and improvements have been made. In this wallpaper sizing machine, wallpaper cloth drawn from a cloth roll is driven by gears or the like. It has a structure in which it is fed to a sizing roll by a feeding roll and a measuring roll, and after sizing, the sizing cloth is sent out through a leveling roll and a slicing machine. The feeding roll, the measuring roll, and the like are rotatably supported by a metal of self-lubricating resin (polyacetal resin or the like) or a bush, and attached to the frame of the gluing machine.

[0003]

In the pasting machine, it has been practiced to provide a power supply ground terminal, but the rubber used for the rubber rolls such as the feeding roll and the measuring roll is the usual insulating rubber. Since the bearing for supporting the roll is also attached to the main body of the gluing machine by the insulating resin, it is electrically insulated from the main body of the gluing machine. For this reason, the site climate (humidity) during gluing work
Depending on the type of cloth used, the working conditions, and other factors, the static electricity generated when the cloth such as wallpaper is disentangled from the original roll, or due to friction with the stay or roll in the middle, gradually charges the rubber roll. , The charge level is rising. When the amount of charge reached the limit, a discharge phenomenon in which a pale spark flew to the metal part of the gluing machine near the shaft center of the roll sometimes occurred. In particular, in a cloth or the like that has been subjected to antistatic treatment, the generated static electricity is hardly charged on the cloth and remains on the roll, so that the amount of charge on the roll is larger than that of a general cloth, and there is a tendency that the cloth is easily discharged.

This discharge causes a pulse-shaped surge voltage and current in the control device of the gluing machine through the metal part of the gluing device, causing a length measurement error in the control device of the gluing device, or stopping the operation. Occasionally, there was a malfunction that occurred.

Further, even if a malfunction does not occur, a worker may feel anxiety because a pale spark flies from the vicinity of the axis of the rubber roll to the frame of the gluing machine.

[0006] As a means for improving this phenomenon,
No. 80799 has been proposed. However, the actual Kaihei 5-8
No. 0799 discloses only a connecting means (grounding) for electrically conducting to a metal part as an antistatic means, and a member for electrically conducting to a rotating roll is required. Has a structure in which static electricity is accumulated from rolls to the entire gluing machine. Regarding grounding, the wallpaper sizing machine is a portable mechanical device that can be brought to a construction site for use, and it may be difficult to connect the ground wire depending on the site. there were. An object of the present invention is to eliminate static electricity or prevent charging without the need for a separate member.

[0007]

In order to solve the above-mentioned problems, the present invention provides a wallpaper sizing machine for pasting a wallpaper between rubber rolls arranged above and below, passing through a predetermined path, and sizing with a sizing roll. Provided is a wallpaper gluing machine (claim 1), characterized in that at least one of the above-mentioned rubber rolls is made of a rubber having a static eliminating action.

[0008] Further, as the rubber having a static eliminating effect in the above-mentioned wallpaper sizing machine, fibers are mixed in a predetermined ratio inside the rubber, and an electric charge opposite to static electricity is induced in the fibers to neutralize the electric charges. A wallpaper sizing machine (claim 2) for removing is also provided.

Furthermore, in a wallpaper sizing machine in which a wallpaper is sandwiched between rubber rolls arranged above and below and a predetermined route is passed, and a sizing roll is used for sizing, at least one of the rubber rolls is provided with an antistatic rubber. A wallpaper gluing machine characterized by being used (claim 3) is also provided.

EXAMPLE FIG. 1 is an example of an example of the present invention whose structure is basically the same as that of a conventional sizing machine, in which a measuring roll (1) and a feeding roll (2) are coated with an antistatic rubber. I am giving it. This rubber (for example, a conductive rubber) has fibers (4) that generate corona discharge mixed therein at an appropriate ratio.

FIG. 2 is a diagram showing the action of removing static electricity.
When static electricity is generated on the measuring roll (1) and the feeding roll (2) due to friction with the wallpaper (3), the generated electrostatic energy is used to charge the opposite ends of the fibers (4) in the rubber. Is induced, and its charge is collected at the tip of the fiber (4) and moves toward static electricity away from the tip (corona discharge) to cause a neutralization phenomenon. As a result, the positive and negative charges are combined and neutralized, and the static electricity is completely removed.

By repeating the above phenomenon instantaneously, static electricity can be removed from the entire surface of the fiber (4).

Rubber having a static eliminating action is a measuring roll (1),
It may be used for at least one of the feeding rolls (2). Further, rubber having an antistatic effect may be adopted.
