The present invention relates to a filter device configured to remove foreign matter therein.

[Conventional technology]

The paint booth is equipped with a paint supply pipe that supplies paint from the paint tank to the paint machine.The paint supply pipes are connected to paint paint outlets at approximately 50 locations around the paint supply pipe at predetermined intervals. Is being supplied.

When using an air atomization type coating machine, a compressed air supply pipe is installed in addition to the paint supply pipe, and the coating machine is connected to the air outlet provided in this compressed air supply pipe to compress the air. Air is being supplied.

However, if paint dregs are mixed in the paint supplied through the paint supply pipe, or if foreign matter such as dust or dirt is mixed in the compressed air supplied through the compressed air supply pipe, it may occur during painting. When it is sprayed from the coating machine onto the object to be coated, it causes a coating defect called "butsu".

Therefore, conventionally, a filter device is provided at the paint outlet and the air outlet to prevent coating failure due to foreign matter.

By the way, since the filter device becomes clogged when it is used for a long time, it has to be replaced once a week.

In automobile painting, etc., piping for 50 to 70 colors is usually used in the painting booth, and there are around 50 paint outlets for each, so 2500 to 3500 filter devices can be installed by simple calculation. Even if this is replaced by 5 to 7 workers, 500 per person
You also have to replace the pieces.

[Problems to be solved by the device]

However, conventionally, the lid of the case accommodating the filter is screwed with a plurality of bolts provided at equal intervals along the outer edge of the case, so that a plurality of bolts can be used when replacing one filter. It is necessary to remove and attach the lid, and further, when the lid is screwed, it is necessary to tighten it with an even force in order to prevent the liquid of the paint from leaking. Therefore, the attaching and detaching work is very troublesome and takes time.

In particular, since the replacement work of the filter must be performed in a short time while the painting line is stopped, there is a problem that if the attachment and detachment of each filter device takes time, the replacement work cannot be completed in time.

Therefore, if the replacement work does not meet the operation start time of the coating line, the coating time has to be shortened, and the operation time of the coating line has to be shortened, which hinders the production plan. If the coating line is operated without finishing the work, there is an unsolved problem that the filter is clogged, and the paint dust that has hardened in the filter portion is discharged from the coating machine, resulting in coating failure.

Therefore, it is an object of the present invention to make it possible to quickly and easily perform a filter replacement work, and to quickly perform this replacement work even if the number of filters to be replaced is large. .

[Means for achieving the task]
