Abstract

The present invention relates to an apparatus for moving coating spray guns, in which coating modules on which spray guns are mounted coat an object while being moving forward and backward on an internal transfer slide in a coating booth. More specifically, upper and lower coating modules on which spray guns are mounted are installed on upper and lower sides of a single transfer slide, and coating is performed while the upper and lower coating modules are moving forward and backward from opposite sides of the transfer slide in opposite directions to intersect each other, and thus the apparatus for moving coating spray guns has a simple integrated structure, thereby providing improved utilization of an installation space. Furthermore, a coating fault is prevented from occurring on an object to be coated, and thus the apparatus for moving coating spray guns provides more desirable efficiency and productivity of coating than a conventional apparatus.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a spray gun,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating spray gun reciprocating apparatus for performing coating of a coating material while a coating module having a spray gun mounted thereon is reciprocated along an inner transfer table in a coating booth, The present invention relates to a spray gun reciprocating apparatus for performing a coating operation by installing upper and lower coating modules equipped with spray guns and carrying out coating while the upper and lower coating modules are reciprocally moved so as to cross each other at opposite sides of the transfer table.

In general, the coating of an object such as a vehicle interior material or various electronic product cases is carried out by a paint sprayed by a spray gun inside a painting booth while conveying the object by a conveyor or the like.

It is very important to prevent such coating defects because the coating of the substrate is uniformly applied to the outer surface of the substrate as a whole.

For this purpose, conventionally, a spray gun is fixedly installed, a coating is applied while the substrate is rotated by a spindle, and a coating method is performed by reciprocating only the spray gun.

The spray gun is reciprocally moved by a coating module. The coating module is provided with a spray gun mounted on a conveyance belt installed in a width direction inside the coating booth. The coating module is conveyed and supplied by a conveyor while reciprocating along the conveyor The paint is uniformly sprayed on the substrate to perform the coating.

At this time, the paint module is not provided with a single spray gun but a plurality of at least two or more spray guns are sprayed in a plurality of directions, so that the paint is evenly coated.

However, in the above-described conventional method, since a single painting module reciprocates on the conveying table, the painting is performed in a range where the paint sprayed by the spray gun does not reach, that is, there was.

That is, since the painting module is reciprocally moved in the width direction by the conveying belt, and the object is forwardly conveyed by the conveyor, the injection position of the paint by the spray gun is sprayed into the waveform shape, . In order to prevent such problems, when the conveyance speed of the substrate is reduced, the coating process takes a long time and the productivity is lowered.

In addition, as a plurality of conveyors for conveying and supplying the substrate are provided in parallel to each other, the longer the distance the reciprocating motion of the paint module is, the greater the range in which the paint sprayed by the spray gun does not reach, As a result, it is difficult to paint a plurality of objects at the same time.
