BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for supplying humidified compressed air, and more particularly, to a device for supplying chip-shaped circuit components which are taken out in a line and supplied in bulk in a component container. The present invention relates to a device suitable for supplying compressed air for conveying circuit components to a (bulk feeder).

2. Description of the Related Art Conventionally, a chip-shaped circuit component supply apparatus is of a so-called sliding hopper type in which a hopper-shaped component container slides up and down. That is, a slope surface having a funnel-like slope is formed on the bottom surface of the parts container, and the upper end of the parts discharge pipe whose tip is opened obliquely is inserted from a through hole opened at the lowest central part of the slope surface. ing. In this state, the component container reciprocates up and down, whereby the component container slides up and down with respect to the component discharge pipe, and the upper end of the component discharge pipe reciprocates up and down relatively within the component container. As a result, the chip-shaped circuit components in the component container are broken down and enter the component discharge pipe one by one. In this way, the chip-shaped circuit components a that have entered the component discharge pipe are sequentially sent downward in a line.

However, such a conventional chip-like circuit component supply device requires a power for reciprocating the component container up and down with respect to the component discharge pipe and a mechanism for transmitting the power to the component container. The configuration becomes complicated as a whole. In addition, the control system of the device is complicated, and the driving operation is troublesome. Therefore, the manufacturing of the device is expensive and the operation is complicated.

In order to solve this drawback, an air-type chip-type circuit component supply device has been developed in which chip-type circuit components are aligned and sent out by blowing air into a component container. This air type chip-shaped circuit component supply device
The compressed air is jetted to the lower side of the component container, and the chip-shaped circuit components are sent to the component discharge path in a vertical line while stirring the chip-shaped circuit components with the compressed air. The chip-shaped circuit components sent to the component discharge path are escaped one by one into a pipe-shaped component transport path by escapement, and transported to a predetermined location through the component transport path.

Conventionally, air used in factories has been used as compressed air sent to such a chip-shaped circuit component supply device. The pressure of the compressed air used in this factory or the like is a relatively high pressure of ³ to 8 kgf / cm ² .

[0006]

The pressure of the compressed air sent to the chip-like circuit component supply device is 0.7 kg.
The pressure is relatively low at about f / cm ² . For this reason, the compressed air having a high pressure used in the factory cannot be used as it is, and the pressure is reduced through a regulator or the like and then sent to the chip-shaped circuit component supply device.

However, when the pressure of the high-pressure compressed air is reduced and sent to the chip-shaped circuit component supply device, the compressed air is injected into the component container of the chip-shaped circuit component supply device, and the humidity of the reduced-pressure air becomes extremely low. For this reason, the humidity of the entire component container is reduced, and the chip-shaped circuit components are attracted to each other by static electricity in the component container. Therefore, the chip-shaped circuit components are solidified without being separated from each other, and the chip-shaped circuit components cannot be smoothly discharged from the component container. In addition, when static electricity is discharged from the chip-shaped circuit component, electricity flows to the internal electrodes through the external electrodes, which may cause dielectric breakdown between the internal electrodes.

Accordingly, the present invention has been made in view of the aforementioned conventional problems,
It is an object of the present invention to provide a compressed air supply device that does not cause static electricity damage due to dry air.

[0009]

Means for Solving the Problems That is, in the present invention,
In order to achieve the above object, in a compressed air supply device for pressurizing and sending out air, a compressor 16 for pressurizing air, an air conditioning room 12 formed around an air inlet 24 of the compressor 16, And a humidifier 14 for humidifying the air in the air-conditioning chamber 12. Note that, in addition to the humidifier 14 for humidifying the air in the air-conditioned room 12, a humidifier 15 for humidifying the air in the air-conditioned room 12 may be provided.

[0010]

In the above-mentioned compressed air supply device, the compressor 16 for pressurizing the air takes in the air from the air-conditioned room 12, and the air in the air-conditioned room 12 is humidified by the humidifier 14 in advance. Therefore, when the compressor 16 pressurizes the air from the atmospheric pressure to a relatively low pressure of about 1 kgf / cm ² , no extreme decrease in humidity occurs. Therefore, when this is sent to the component container or the like of the chip-like circuit component supply device, the inside of the component container does not become in an extremely low humidity state, and charging of the chip-like circuit component or the like can be prevented. The air conditioning room 1
In addition to the humidifier 14 for humidifying the air in the
When a humidifier 15 for humidifying the air inside the humidifier is provided, the excess humidity in the air-conditioning room 12 is swiftly humidified when the dehumidification occurs due to excessive humidification, so that the humidity becomes normal. It is possible to maintain the air-conditioned room 12.

[0011]

Next, an embodiment of the present invention will be described in detail with reference to FIG. FIG. 1 is a schematic view of a compressed air supply device according to an embodiment of the present invention. As shown in FIG. 1, the housing 11 is divided into three sections, and one section is provided with a compressor 16 for pressurizing air from atmospheric pressure to a relatively low pressure of about 1 kgf / cm ² .
The compressed air pressurized by the compressor 16 is sent through a compressed air supply pipe 21 to, for example, a component container of a chip-shaped circuit component supply device described later.

The other section of the housing 11 is an air-conditioning room 12, which is provided with an air intake 13 for taking in air from outside the housing 11, and the air of the compressor 16. Entrance 24
Is inserted. Therefore, as shown by the rightward arrow in FIG.
The air-conditioning chamber 12 passes through the air-conditioning chamber 12, is introduced into the compressor 16 from the air-conditioning chamber 12, is pressurized, and is sent to a predetermined position through a compressed air supply pipe 21. A sensor head 17 of a humidity sensor 18 is introduced into the air-conditioned room 12 so that the humidity in the room 12 is measured.

A humidifier 14 and a humidifier 15 are installed in another section of the housing. The humidifier 14
The water sent from the water supply unit 22 side through the valve 23 is vaporized and sent to the air conditioning room 12 to humidify the air conditioning room 12. The humidifier 15 removes moisture from the air in the air-conditioning chamber 15 and humidifies the air to dry the air. The operation of the humidifier 14 and the humidifier 15 is controlled by a controller 19, which controls the value of the humidity (relative humidity) in the air-conditioned room 12 measured by the humidity sensor 18. Feedback control is performed. That is, when the humidity value measured by the humidity sensor 18 is lower than the predetermined set value, the humidifier 14 operates to humidify the air in the air conditioning room 12. On the other hand, when the humidity value measured by the humidity sensor 18 is higher than a predetermined set value, the dehumidifier 15 operates to gradually dehumidify the air in the air conditioning room 12. Thereby, the humidity of the air in the air-conditioning room 12 is maintained at a state substantially equal to the set value.

The humidity of the air-conditioning room 12 measured by the humidity sensor 18 is also input to the drive controller 20 of the compressor 16, and the operation of the compressor 16 is stopped in the event of trouble such as abnormal decrease or increase in humidity. I do.
As described above, in the compressor 16, air is introduced from the air conditioning room 12, and the air is pressurized and sent to a predetermined position through the compressed air supply pipe 21, so that the air conditioning room 12 is maintained at an appropriate humidity. By doing so, compressed air having appropriate humidity can be sent from the compressor 16. In the above embodiment, the compressor 16, the air conditioning room 12, the humidifier 14, and the humidifier 1
5 is integrated by the housing 11, but such a layout can be changed as appropriate.

FIG. 2 and FIG. 3 show a chip-shaped circuit component supply device for sending compressed air from the compressed air supply device according to the embodiment. In this chip-shaped circuit component supply device,
A partition 42 is provided in the component container 1, a component discharge chamber 6 is formed below the partition 42, and the chip-shaped circuit components a, a,. The chip-shaped circuit components a, a ...
Enters the parts discharge chamber 6 from a partly opened portion of the partition 42. Compressed air is injected into the component discharge chamber 6 through an air supply pipe 4 connected to a compressed air supply pipe 21 of the compressor 16 via a regulator or the like. Then, due to the pressure of the air, the pressure inside the component discharge chamber 6 becomes higher than the other portion of the component container 1. For this reason, the chip-shaped circuit component a outside the partition 42 is pushed by this pressure, and the component discharge chamber 6
Is prevented from entering. Since the injected air circulates in the component discharge chamber 6, the chip-shaped circuit components a, a,... In the component discharge chamber 6 are carried by the air and disturbed in the component discharge chamber 6. While circulating. While the chip-shaped circuit component a circulates in the component discharge chamber 6 in this way, a part thereof reaches the upper end of the component discharge path 48. The air sent from the air supply pipe 4 to the parts container 1 is mainly discharged through the parts discharge path 6 through the parts discharge path 48, so that the chip-shaped circuit component a enters the parts discharge path 48 by this flow of air. From there, they are sent vertically down in a row.

The chip-shaped circuit component a entering the component discharge path 48 enters a component storage hole 64 for accommodating only one chip-shaped circuit component a of the slider 54, and the slider 54 reciprocates right and left in FIG. Thereby, the components are alternately discharged one by one into the two pipe-shaped component transport paths 10 and 10. Then, it is transported to a predetermined location through the component transport path 10. Since compressed air whose humidity has been adjusted is sent from the compressed air supply device to the component container 1 of the chip-shaped circuit component supply device, the chip-shaped circuit components a, a ... in the component container 1 are charged. Hard to do.

[0017]

As described above, according to the present invention, since the air in the air-conditioning room 12 humidified by the humidifier 14 is pressurized by the compressor 16 and supplied, the extreme humidity of the supply destination side is reduced. Drop can be prevented. Therefore, when this is sent to the component container or the like of the chip-like circuit component supply device, the inside of the component container does not become in an extremely low humidity state, and charging of the chip-like circuit component or the like can be prevented. Further, in the case where the humidifier 15 for gradually humidifying the air in the air-conditioning room 12 is provided, when the humidity in the air-conditioning room 12 becomes particularly high, the excessive humidity is swiftly humidified, and the normal humidity It is possible to maintain the air-conditioning room 12 at the same time. For this reason, it is possible to quickly respond to a change in humidity due to disturbance or the like, and it is possible to reliably maintain an appropriate humidity.
