Description

Among the methods for removing static electricity charged to the human body and other than the human body, the present invention eliminates static electricity that neutralizes the charge of the charged object by creating a charge of a different polarity from the charged object with Teflon (registered trademark) or silicone. The present invention relates to a method and a static eliminator.

In daily life, when a human body moves such as walking, static electricity is generated due to friction of clothes. In addition, carpets are provided on the hotel floor, and when you walk on the carpet, your body is charged with static electricity, and the static electricity is not discharged naturally but increases. When touching a door handle or metal furniture, the static electricity charged on the clothes will rapidly discharge and give a strong impact.
Also, on the industrial side, when paper, resin film, cloth made of chemical fibers, etc. move in the air in the manufacturing process, they are charged by friction with air, which causes obstacles on the work surface, and fine dust. There is also a problem in terms of quality such as adhesion, and various removal devices are used for that.

In general, in the case of a human body, it is known that when charged to 3 KV or more, a sag or electric shock due to electrostatic discharge is felt. Therefore, as a method of removing static electricity disturbance, a method of extending the discharge time of static electricity using a high resistance body, a static eliminator that aims to prevent galling and electric shock by gradually discharging by corona discharge,
(For example, Patent Document 1)
Some discharge the charged electric charge, and some discharge it with a conductive fiber, a discharge tube, etc. and use an LED to confirm the discharge.
(For example, Patent Document 2)
Moreover, the thing which discharges static electricity with clothes, a bracelet, etc. using an electroconductive member is raised as a prior art.
(For example, Patent Document 3)
In the manufacturing process, the problem is solved mainly by generating and neutralizing negative ions at a high voltage.
(For example, Patent Document 4)

Further, as a state-of-the-art static eliminator, a removal method that does not require grounding using a varistor or the like after static electricity is once stored between conductors by electrostatic induction is also cited as a prior art.
(For example, Patent Document 5)
However, even in the above prior art, the charge charged to the human body can be removed without grounding. However, against the charge of the person himself / herself, the charged charge can be obtained by grounding with a high resistance, discharge tube or the like. There are various types of removal tools to be removed. However, there is no removal tool for removing static electricity from a person other than the person himself / herself.

Japanese Patent Laid-Open No. 10-316321 Japanese Patent Laid-Open No. 2001-35684 Japanese Patent Laid-Open No. 01-251598 JP 2009-170230 A Patent No. 4024214

The conventional ones are mainly used to discharge the charged charges to the ground, and are discharged with a discharge tube, high resistance, conductive fiber, etc., and the LED is used to check the discharge. However, some static electricity exceeds 10 KV, so there are many failures, and there are many failures in terms of reliability. Particularly recently, popular LEDs are vulnerable to high voltages and may fail due to high voltage static electricity. In addition, the method of using a conductive member, conductive fiber, and the like and removing it by discharge is not effective for all because the discharge itself varies depending on the atmosphere. In addition, those caused by discharge in the air cannot be used everywhere in the presence of volatile flammables, such as gas stations, because there is a danger of ignition. Antistatic sprays are also known, but there is an annoyance that must be sprayed for each ex-post response, and there is a method and remover that can always remove static electricity charged on the human body or clothes. It was desired. The above-mentioned static eliminator of Patent Document 5 seems to be perfect for the person's own static eliminator holding the static eliminator. In addition to removing static electricity from the person himself, There is a need for a removal tool that can simultaneously remove the charge of an object.

The first technical means of the present invention for solving the above problems is in the hollow part of a pipe made of fluororesin such as Teflon (registered trademark) or in the hollow part of a tube made of silicone rubber. In addition, a monopolar discharge tube such as a neon tube or a green tube, or a static eliminator is inserted, and a state in which air blocked from outside air is held in the hollow portion of the pipe or in the hollow portion of the tube is formed. Thus, the problem is solved by a static eliminator that seals both end portions with a conductive member and removes static electricity charged on a charged object contacting the pipe, tube, or conductive member.

The second technical means of the present invention for solving the above-mentioned problem is that a hollow portion of a pipe made of a fluororesin such as Teflon (registered trademark), a monopolar discharge tube such as a neon tube or a green tube, or In addition, the static electricity removing body is inserted, and both ends are sealed with metal fittings so as to form a state in which the outside air is blocked from the outside air in the hollow portion of the pipe. The problem is solved by a static eliminator that is configured to remove static electricity that is connected to the human body and other charged objects away from the human body through high resistance.

The third technical means of the present invention for solving the above-mentioned problems is that a hollow portion of a flexible tube made of silicone rubber is provided with a monopolar discharge tube such as a neon tube or a green tube, or a static eliminator. Inserting and forming an endless tube that can be contacted with the human body in a state where the air in the hollow portion of the tube is blocked from the outside air, and the neck part of the human body, the arm wrist part, the finger part, or The problem is solved by a static eliminator that is configured to remove static electricity charged on the human body by an endless tube that is detachably attached to a desired site such as an ankle periphery.

The fourth technical means of the present invention for solving the above problems is in the hollow part of a pipe made of a fluororesin such as Teflon (registered trademark) or in the hollow part of a tube made of silicone rubber. Unipolar discharge tubes such as neon tubes and green tubes, or both ends so as to form a state in which static air is removed from the outside of the pipe or tube while inserting a static eliminator. This is solved by a static electricity removing method characterized in that the static electricity charged to the charged material contacting the pipe or tube or the conductive member is removed.

  As described above, unlike the conventional discharge method, it is possible to remove charged objects other than the person himself / herself, and the person himself / herself can remove the static electricity simply by touching the main body without grounding. When using a Teflon (registered trademark) pipe, it can be attached to the inside of the pipe when a charged object or charged person touches the pipe, or by rubbing the outer surface of the Teflon (registered trademark) pipe. Since the green tube emits light, it can be used as a slight illumination near the hands at night. When silicone rubber is used, static electricity can be removed at any time without touching the static eliminator by attaching it to the wrist or the like.

  The present invention was created based on a completely new concept in order to solve the above-mentioned problems, and the intent is to prevent the generation of static electricity itself, but to suppress the generation of electric charges, Teflon (registered trademark) is considered to have a method of suppressing the charge, storing the charge quickly without discharging it, and neutralizing the charge of the charged object by creating a charge different from the charge of the charged object. Alternatively, a method of neutralizing the charge of a charged material by creating with silicone rubber was devised.

There is a charged column as a measure of the polarity of the electrostatic charge. It was difficult to determine the polarity because there were various combinations of materials that were rubbed together and arranged in order from those that were easily charged positively. The inventors investigated various substances and investigated and experimented with Teflon (registered trademark) and silicone rubber over a long period of time. As a result, they found out the following.

First, Teflon (registered trademark) and silicone rubber almost have a negative charge from zero, and even if they rub against other substances, they always have a negative charge. {Friction between Teflon (registered trademark) and silicone rubber In this case, the silicone rubber may be slightly positively charged. It was found that the charge is maintained from zero to negative in both low humidity and wet conditions, as shown in FIG. In addition, it has been found that the charging potential changes greatly depending on the shape, and the charging time also changes.In particular, the pipe-shaped one is formed in a loop shape while holding the air blocked from the outside air inside, The same change can be achieved by significantly increasing the charge amount and charging time, and by applying physical stress such as touching or rubbing the human body to both Teflon (registered trademark) and silicone rubber. Than produce it.

In a normal state, the surface of the silicone rubber maintains a negative voltage of about 0.3 KV to 3 KV. However, in a state where a human body is in contact with a hollow portion and air inside, the surface is 3 KV to 10 KV. Negative voltage rises to the order.
From these things, Teflon (registered trademark) and silicone rubber can be used as the standard for negative charge as the charging potential is almost always minus, and based on this, the second technique for solving the problem described above. As a means, it has become possible to devise a method of neutralizing the charge charged on the human body and removing static electricity by using a discharge tube or a static electricity removing body inserted into the hollow portion of the pipe.

The basic technical means of the present invention is that a fluororesin such as Teflon (registered trademark), a pipe made of silicone rubber, or a tube, or a tube that holds air blocked from outside air in a hollow portion, The fact that a negative charge can be obtained for a long time on the surface of the silicone rubber is utilized.
In addition, when water is put into the hollow portion, the surface of the silicone rubber tube has a charge of about 0V.

It is also confirmed that if air is held in the hollow part, dust in the air collects and adheres to the surface of the silicone rubber, that is, a negative charge is held because it becomes a kind of dust collector it can.

2, 3, and 4 show the state of charging and discharging, but in FIG. 2, when a static eliminator is not used, the charge charged to the clothes passes through the palm and the contacted conductor is charged by electrostatic induction. It discharges between the electric charges of different polarities and causes an impact. When the human body is charged to (+) or (−), it is discharged and subjected to an impact between a charge opposite to the human body due to electrostatic induction.
FIG. 3 shows a discharge state when the static eliminator of the present invention is attached to the wrist.
In the case of a low voltage, the positive charge charged on the clothes is removed by neutralizing with the negative charge charged on the silicone rubber tube.

In the case of a high voltage, recently, clothes such as acrylic fibers may generate a negative charge close to 10 KV. In this case, the static rubber formed in the discharge tube and the connection part of the hollow part of the silicone rubber tube. Neutralized and removed by an electric removal tool. The same effect can be obtained by holding a Teflon (registered trademark) pipe in hand.

What can be removed by neutralization is from Teflon (registered trademark), the negatively charged 5 to 10 KV of silicone rubber, and the rest must depend on discharge or the like. Therefore, in order to cope with even a high voltage exceeding 5 KV, it is configured to be removed by a static eliminator inserted in a hollow portion of a Teflon (registered trademark) pipe or a silicone rubber tube. Generally, a person is shocked by a voltage of 3 KV or more, and if it is 1 KV or less, the person does not feel the shock. Depending on the situation of use, the static eliminator is one that discharges between 18 V and 250 V, and the discharge tube is between 80 V and 2.5 KV.

The static eliminator of the present invention uses neutralization, a discharge tube, a static eliminator, etc. when removing static electricity. Unlike discharge in air by an ionizer, conductive member, etc., volatile gas It can be used safely even in an atmosphere of

A green tube 6 and a resistor 7 of 15 MΩ are provided inside the Teflon (registered trademark) pipe 1. It is inserted. Static electricity of about 2 KV or less is neutralized with a negative charge charged on the Teflon (registered trademark) pipe, and when it is about 2 KV or more, it is removed by discharging the green tube.
The metal part of the pipe sealed at both ends is a contact terminal used for removing static electricity charged on charged objects other than the person himself / herself. By bringing the metal part into contact with the charged object, the static electricity of the charged object is removed. At that time, the human body only needs to touch the Teflon (registered trademark) pipe, and the metal parts at both ends are connected to each other with a high resistance of 15 MΩ. This resistance value can be used in the range of 1 to 20 MΩ.
To charge yourself, touch the Teflon (R) pipe body other than the metal part or one of the metal parts. It can be removed by neutralization or by a green tube in the hollow part of the pipe.
The green tube 6 has a monopolar structure and is inserted into the hollow portion of the pipe in an electrically unconnected state. Light is generated by the electric charge charged in the pipe. Also, by rubbing the outer surface of a Teflon (registered trademark) pipe, the green tube generates light and can be used as a lighting fixture near the hand at night. The discharge voltage of the green tube is about 2 KV.

FIG. 8 shows the static electricity removing tool according to claim 3, wherein the flexible tube 11 made of silicone rubber is formed in a loop shape in a state of keeping air blocked from outside air, and can be attached to and detached from the wrist portion of the human body. It is an endless tube that can be attached to the tube. The static eliminator 13 is used as a joined body sealed at both ends for forming a loop. In addition, a charge collecting body 12 made of a plurality of magnetic materials is idled on the outer periphery of the silicone rubber tube 11 so as to collect charges that charge the human body. The current collector need not be used.

FIG. 9 is a schematic view of the inside of the electrostatic removal body 13. The cylindrical varistor 8 discharges and absorbs the electric charge stored between the conductor 14 and the conductor 15. These are fixed by fixing screws 16. The conductor 14 is made of a conductive pipe, and a part of the outer periphery of the pipe is in electrical contact with the internal electrode of the cylindrical varistor 8, and the conductor 14 uses the outer periphery to make the silicone rubber tube endless. It also plays the role of a joined body for forming into a tube. FIG. 10 shows the structure of the cylindrical varistor 8, and the cylindrical varistor is composed of the external electrode 9 and the internal electrode 10, and the discharge voltage of the cylindrical varistor is 80V. You can choose anything up to the rank.

FIG. 11 shows the static eliminator shown in FIG. 6 miniaturized and attached to a part of the necklace. The necklace is a metal chain 20. The chain 20 may be other as long as it is conductive, but metal is the best. Static electricity around the chain and near the removal tool is always removed, and even if the hand touches the chain and the removal tool, the touched hand is removed by static electricity and there is no impact.

FIG. 12 is a schematic process diagram of a process of cutting the raw material of the polyester fabric for curtain into a certain size. Usually, the raw material 22 wound around the roll is cut by the guide rolls 23, 24, 25. Although the material is transported to the air up to 26, the original fabric is charged by friction with air, and the stacked fabric 27 after cutting stores a charge of a voltage close to 40 KV. The worker was wearing gloves and removing electricity using a metal rod.
