Description

  The present invention relates to an electrostatic static eliminator that uses a fan motor suitable for free layout, and can be easily adapted to a small area or a wide area according to the shape and position of an object to be eliminated.

  An electrostatic static eliminator, a so-called ionizer, is a device that neutralizes static electricity that causes troubles such as electrostatic breakdown and malfunction of equipment with ions, and performs static elimination. The ionizer is divided into an AC system and a DC system depending on the method of generating ions. In the AC system, an AC voltage is applied to the discharge needle to alternately generate + and − ions. In the DC system, a DC voltage is applied to the discharge needle. Apply and generate only + or-ions.

  Conventionally, as this type of electrostatic static eliminator (ionizer), a bar-type electrostatic static eliminator 100 (FIG. 3), which requires an air pipe 101 using a compressor, as in Cited Document 1 (Japanese Patent Laid-Open No. 2009-16096), In addition, as in Cited Document 2 (Japanese Patent Laid-Open No. 2005-347270), a small box-type electrostatic static eliminator 110 (FIG. 4) using a fan motor 111 for neutralizing an object to be neutralized having a small static eliminating area, or cited document. 3 (Japanese Patent Laid-Open No. 2009-43580), there is a connection type static eliminator (FIG. 5) in which the static eliminator 120 is connected by a connection connector 121.

  However, in such a conventional static eliminator, the bar-type static eliminator 100 of Patent Document 1 is a type that uses a compressor and uses an air pipe 101, and has a large air volume and wind pressure. Although it has a high capacity and can deal with a wide range of objects to be neutralized, there is a limit to the place where the static electricity neutralizer is installed because the air pipe 101 is required.

  Furthermore, since the ion injection unit is fixed, there is a problem in that it is necessary to use the rotation of the injection nozzle 102 or an ion transport tube depending on the shape of the object to be neutralized.

  In the static eliminator 110 of Patent Document 2, a discharge needle 112 is disposed behind a fan motor 111 through which an airflow flows, and a finger guard 113 and a rectifying plate 114 are disposed in front of the fan motor 111.

  As in Patent Document 2, in a small box type electrostatic static eliminator 110 using a fan motor 111 for neutralizing an object to be neutralized having a small area to be neutralized, it can be flexibly installed on the object to be neutralized. However, since the static electricity elimination device 110 is limited to one static electricity removal point, the area of the object to be neutralized is wide, or the static electricity removal area can be used to eliminate multiple points. Since it is necessary to prepare a plurality of static eliminators 110 so as to be able to do so, there is a problem that the cost is high and a large space is required for the static eliminator 110.

  5 (a) and 5 (b), the static electricity eliminator 120 that connects the static electricity eliminator 120 with the connection connector 121. By connecting the static electricity eliminator 120 with the connection connector 121, the object to be neutralized. Although there is a degree of freedom corresponding to the size of the area, as in Patent Document 1, air piping is required using a compressor, and the ion injection nozzles 122 of each static eliminator 120 are fixed. Depending on the shape of the object to be discharged, there is a problem that an adjustment mechanism for the injection nozzle 122 must be provided (see Patent Document 3).

  The present invention has been made paying attention to such a conventional problem, and constitutes one ion generation unit provided with a fan motor and a discharge needle for generating ions, and one high voltage generation device. In addition, an arbitrary number of the ion generating units can be connected directly or using a flexible pipe, and a plurality of static elimination points can be taken in accordance with the target to be eliminated, and the air volume is not reduced, and the distance can be reduced. It is an object of the present invention to provide an electrostatic static eliminator using a fan motor that can be neutralized up to the point.

The plurality of ion generation units connected to each other are connected to the ion generation power source of the high voltage generation device via an ion generation power cable, and the high voltage generation device is connected to the high voltage generation device via a fan motor driving power cable. It is connected to the power supply for driving the fan motor.
The present invention is also characterized in that a flexible pipe is used for a connecting portion for connecting the ion generating units to each other.
Furthermore, the present invention resides in that a connecting pipe as the connecting portion is provided on the side wall surface of the ion generating unit, and the connecting pipes are connected to each other.

According to the first aspect, the number of static elimination points can be easily changed in accordance with the change of the static elimination target object, and the ability to adapt to the usage conditions of the electrostatic static eliminator is increased. Furthermore, since one high voltage generating part can be provided, it is advantageous in terms of cost and space.

For example, if ion removal was performed with two ion generation units, but the object to be removed became larger, and it was desired to double the charge removal points, add two ion generation units 2 ₁ , 2 ₂ , 2 _3. Four is sufficient. In addition, since the neutralization capability of the ion generation units 2 ₁ , 2 ₂ , and 2 ₃ does not change depending on the number used, mutual interference between the ion generation units 2 ₁ , 2 ₂ , and 2 ₃ when the number is changed from 2 to 4 If I is ignored, the static elimination capability is simply doubled.
