Description

  The present invention relates to a static eliminating device for an automatic wallpaper pasting machine. More specifically, the present invention relates to an automatic wallpaper pasting machine that discharges static electricity generated by a slitter installed in the automatic wallpaper pasting machine to a commercial power source.

  Conventionally, in an automatic wallpaper pasting machine, static electricity is generated due to friction between the wallpaper and the roller when the wallpaper is conveyed by a roller, and the amount of static electricity generated depends on the material of the wallpaper, the material of the roller, the speed at which the wallpaper is discharged, It varies depending on the length of the wallpaper to be discharged, and also depends on the environmental conditions (temperature and humidity) at the time of work. Regarding wallpaper material, paper wallpaper generates relatively little static electricity, but vinyl wallpaper and inorganic wallpaper generate particularly much static electricity.

  Also, rubber rollers, stainless steel rollers, aluminum rollers, carbon rollers, etc. are used as rollers for wallpaper pasting machines. Static electricity is generated by any roller, but in the case of rubber rollers, static electricity is particularly generated. .

  On the other hand, the roller bearings of automatic wallpaper pasting machines use resin bearings because they want to use cheap and easy-to-slip materials. In automatic wallpaper pasting machines using such resin bearings, When transporting wallpaper with a roller, static electricity is generated due to friction between the wallpaper and the roller, and the roller is charged. In the wallpaper pasting machine, the distance between the metal part (shaft) of the roller and the metal frame of the wallpaper pasting machine is generally from several millimeters to several tens of millimeters, so that the roller is from several kV to several tens of kV or several tens of kV. When electrified, discharge to the metal frame of the wallpaper pasting machine occurs, but this becomes electromagnetic noise, causing electronic components of the control unit that controls the automatic wallpaper pasting machine, such as a microcomputer, to malfunction. Sparks fly, make a bang, and the operator often feels terrified.

  In order to prevent such troubles due to the occurrence of static electricity, in the present applicant, static electricity generated on each roller including a measuring roller, a pressing roller, and a high tension roller installed in the wallpaper transport path of the automatic wallpaper pasting machine. As a means to release the air to the conductive frame, the roller bearing member is made of conductive resin, the roller shaft and the conductive frame are connected by a conductive spring, and the conductive frame and the commercial power source are connected by a surge absorbing element. Thus, there has been proposed a static eliminator for an automatic wallpaper pasting machine that allows the static electricity generated inside the automatic wallpaper pasting machine to be discharged to a commercial power source when the static electricity is charged to a predetermined voltage or higher.

Japanese Patent No. 4590622

  Static electricity generated in the main body of the automatic wallpaper pasting machine can be removed by the solution described in the prior art. However, the slitter attached to the automatic wallpaper pasting machine is lighter and lower in cost. Because the left and right frames are made of resin material for the purpose, static electricity generated by friction between the tension bar provided on the slitter and the wallpaper accumulates in the tension bar, and discharges to the worker when the worker touches the tension bar. There is a danger. In addition to the tension bar, the slitter generates static electricity due to friction with the wallpaper on the upper blade, the lower blade, the guide roller provided between the upper blades, and the cross guide provided on the lower blade mounting stay. There was a problem that the work had to be done while paying sufficient attention to this part.

The present invention solves the above-described problems, and absorbs surge generated by friction between the roller provided on the main body of the automatic wallpaper pasting machine and the wallpaper from the conductive frame of the main body of the wallpaper pasting machine to the commercial power source. An automatic wallpaper pasting machine provided with a slitter having an upper blade, a lower blade, and a tension bar, which is detachably provided on the wallpaper sending side end face of the wallpaper pasting machine main body provided with an element. A static electricity removing device, wherein a charge transfer member is provided on the end face of the wallpaper sending side of the wallpaper pasting machine main body, and an upper blade and a lower blade are provided on the synthetic resin frame of the slitter. a blade and the lower blade mounting stay on that attached to the slitter frame, the conductive fixing member for fixing the upper blade and the stay and the tension bar end mounting the lower blade to each of the slitter frame, the wall The slitter side charge transfer member provided at a position facing the charge transfer member provided in the gluing machine main body and the conductive fixing member communicate with each other, and the end portion is fixed by the slitter side charge transfer member. Conductor of the main body is installed through the charge transfer member provided on the main frame of the automatic wallpaper gluing machine from the conductive fixing member, the lead wire and the slitter side charge transfer member. The charge is transferred from the frame to the commercial power supply.

  The automatic wallpaper pasting machine of the present invention is provided with a charge transfer member on the frame end surface on the wallpaper sending side of the wallpaper pasting machine body, and the slitter is attached with upper and lower cutters to which the upper and lower blades of the slitter are attached. A conductive fixing member that fixes the stay and the tension bar end to the synthetic resin slitter frame, and a slitter side charge transfer member provided at a position facing the charge transfer member provided in the wallpaper pasting machine body; The conductive fixing member is communicated, a conductive wire whose end is fixed by the slitter side charge transfer member is provided, and static electricity generated by the slitter is provided from the slitter side charge transfer member to the wallpaper pasting machine body. Since the charge is transferred from the main body frame to the commercial power supply via the charge transfer member, static electricity generated by the slitter's tension bar and cross guide As the charge moves to the slitter side charge transfer member via the lead wire and escapes from the wallpaper paste machine body frame to the commercial power supply, even if the slitter's left and right frames are made of lightweight and inexpensive synthetic resin, they are generated in the slitter Since static electricity does not accumulate in the slitter, the worker can be provided with an automatic wallpaper pasting machine that is free from fear of discharge and can work with peace of mind.

  In addition, the wallpaper pasting machine main body has a path for discharging the static electricity generated by each roller to the conductive frame, and by setting each roller and the conductive frame to the same potential, the gap between each roller and the conductive frame is obtained. In addition, even if the operator cannot connect the ground wire due to the circumstances of the site, if the rollers and the conductive frame become more than a certain fixed potential due to the generated static electricity, they will accumulate. Therefore, it is possible to provide an automatic wallpaper pasting machine in which the operator does not feel a fear due to the discharge of static electricity and the malfunction of the control unit does not occur.
