JPS59190392A - Introducing device of air into dip treating material - Google Patents

Abstract

PURPOSE:To eliminate the need for the operation of setting and resetting with each dip treating material and the device for moving a conduit by introducing air into the recess of the dip treating material from below by an air supplying pipe provided on the bottom of a treating vessel in the outlet part thereof, thereby preventing the deformation of the treating material. CONSTITUTION:When a cabin 1 is dipped via a suspension means 4 by a conveyor 3 into the electrodepositing liquid 6 in an electrodepositing vessel 2, the liquid 6 is filled in the recess 1b of the cabin 1. When the front side of the cabin 1 is lifted and is taken from the surface of the liquid 6 in the outlet part 7 of the vessel 2, a negative pressure is generated in the recess 1b but the kicker 15 of the means 4 turns on the 1st switch 16, then a control device 14 drives a pump 13 to eject air from the ejecting holes 10c of an air supplying pipe 10 and to introduce the air into the recess 1b, thereby restoring the atm. pressure in the recess 1b and preventing the deformation. The cabin 1 is further lifted and when the atm. air enters the recess through a window opening 1d, etc., the kicker 15 thrns on the 2nd switch 17 to stop the ejection of the air from the holes 10c.
