Precision equipment, plastic products, and other conveyed items are constantly vibrated while being conveyed and fed by falling, so static electricity is generated due to friction, and adjacent parts may stick to each other, making it impossible to drop and feed them one by one. . When conveyed articles adhere in this way, there is a drawback that the supply speed decreases, resulting in a supply shortage and the efficiency of the production line decreases. Electronic parts, precision instruments, plastic products, etc. are often worked in clean rooms to avoid fine dust.However, clean rooms have low humidity and are kept constant, so static electricity is easily generated, and conventionally There were many accidents. Conventionally, such a situation has been dealt with by mechanically taking it out using a pickup device or by adding a supply device such as a parts feeder.
しかし、かかる対処の仕方はいずれも機械を増設しなけ

ある。FIG. 1 shows an embodiment of a humidifier for preventing the generation of static electricity, which is used directly in carrying out the method for preventing the generation of static electricity according to the present invention, in which external air is mixed with humidified air. This embodiment is applied when the supply pressure of the air pump is low or when it is necessary to adjust the humidity of humidified air. The humidifier 1 for preventing static electricity generation includes a box-shaped main body case 2,
A water tank 3 for storing water stored in the main body case 2, a porous bubble generator 4 provided in the water tank 3, and a fan 5 for blowing air provided at the upper part of the main body case 2. Be prepared. The water tank 3 has a box shape smaller than the main case 2, and a humidifying chamber 6 is formed in the upper part, that is, between the water surface and the ceiling of the main case 2. The humidifying chamber 6 is connected by a duct 7 to a conveyance space 9 of a supply device 8 such as a parts feeder. The articles (conveyed articles) conveyed by the feeder 8 include electronic parts, precision equipment, plastic products, etc. The 1 L air distribution bubble generator 4 is made of a sintered body of metal such as stainless steel, brass, or ceramics. It is connected to an air pump 11 through a pipe 10 to supply air bubbles into the water. The fan 5 is installed to blow outside air, and its installation position itself is arbitrary as long as it can blow air into the humidifying chamber 6. The duct 7 is connected between the ceiling of the humidification chamber 6 and the ceiling of the conveyance space 9, and conducts humidified air produced in the humidification chamber 6 to the conveyance space 9. The air pump 1 does not have to be a dedicated one, and may also be used for other machines. In the figure, 12 is a handle for taking in and out of the water tank 3, 13 is a water meter for adjusting the amount of water stored in the water tank 3, 14 is a controller for controlling the humidifier 1 for preventing static electricity generation, and 15 is a handle for taking in and out of the water tank 3. The cover 16 of the transport space 9 is a chute for dropping the material from the transport space 9 into a container (not shown) or the like. The operation of the first embodiment having the above configuration will be explained. When the air pump 11 is operated and air is bubbled into the water from the bubble generator 4, the humidity of the air in the humidifying chamber 6 gradually increases. On the other hand, since external air is supplied from the fan 5 into the humidifying chamber 6, the humidity of the humidifying air is adjusted appropriately, and the humidity is adjusted inside the conveying space 9 via the duct 7 by the wind pressure of the fan 5. humidified air is flowed in. Therefore, although the humidity in the work room is maintained at a predetermined level, only the humidity in the transport space 9, that is, the humidity around the transported articles is locally increased. Therefore, generation of static electricity is prevented, and transported articles do not stick to each other. Therefore, the conveyed articles are dropped and fed one by one from the chute 16, and the feeding speed of the feeder 8 is maintained at a predetermined speed. In addition, the humidified air flowing into the conveying space 9 is prevented from becoming saturated because external air is appropriately introduced by the fan 5, so that dew condensation is prevented. This results in
Even if the conveyed article is made of metal, rusting is prevented, so it can also be applied to electronic parts, precision equipment, etc. The humidity of the humidified air in the humidifying chamber 6 is regulated by measuring the humidity in the conveying space 9 with a hygrometer (not shown) and adjusting the air volume and air pressure of the fan 5 as appropriate based on the results. The humidifier for preventing static electricity generation according to the present invention is not limited to the above embodiments. For example, a configuration as shown in FIG. 2 may be used. That is, a bubble generator 4 is installed below, and a humidifying chamber 6 is installed in the E section.
The water tank 3 in which the water tank 3 is formed is connected to an air jet body 18 via an air filter 17 and a hose 7a. The air blowing body 18 is provided with a nozzle 18a for supplying air to the chute 16. In this case, the space inside the shoe [6 is the conveying space 9. In this case, since humidified air is supplied through the air filter 17, dew-condensed moisture in the air can be removed by the air filter 17, thereby preventing rusting of the transported articles. In this embodiment, the air supply from the air pump 11 is applied to dogs. In the figure, parts having the same functions as those in the embodiment of FIG. 1 are given the same reference numerals for convenience. Effects of the Invention As described above, according to the method for preventing the generation of static electricity and the humidifier for preventing the generation of static electricity according to the present invention, it is possible to prevent the generation of static electricity that occurs in conveyed articles. This has the effect of making it possible to maintain speed.
