1 is an illustration of a coating booth of a powder coating equipment according to the prior art.
2 and 3 illustrate the configuration of a variable powder coating booth capable of producing a small amount of various types according to an embodiment of the present invention.

Hereinafter, embodiments of the present invention having the above-described features will be described in more detail with reference to the accompanying drawings.

Referring to FIGS. 2 and 3, a variable powder coating booth capable of producing a small amount of various kinds according to an embodiment of the present invention will be described in detail as follows.

First, the transfer rail 110 is a pretreatment line for degreasing by degreasing by spraying a degreasing liquid (not shown) and removing foreign substances and grease from the conductor 200 by spraying washing water, and a hot air dryer (not shown). A drying line that removes water from the conductor 200, a powder coating line that performs powder coating on the conductor 200, and the powder coated in a hot air dryer (not shown) are cured on the conductor 200. It is a hardening line that is fixed to the ceiling of the installation space to sequentially transfer the conductor 200.

Next, the hook 120 is configured to be conductive, and is formed in a hook shape coupled to the lower end of the transfer rail 110 through a roller 121.

Here, it is electrically connected to the hook 120 through the transfer rail 110 or a separate wiring line.

Next, the hanger 130 is made of a conductor bent in an S shape on which the hook 120 is mounted at one end and the conductor 200 is mounted at the other end, and a hanger body electrically connected to the hook 120 and a hook The upper current conducting member detachably coupled to the exterior according to the shape of one end of the hanger body mounted on 120, and the lower conducting member detachably coupled to the exterior corresponding to the shape of the other end of the hanger body on which the conductor 200 is mounted. And, it is composed of an insulating member coupled to the exterior of the straight hanger body except for the upper conductive member and the lower conductive member forming region.

Here, the hook 120, the upper energizing member, the hanger body, the lower energizing member, and the conductor 200 may be electrically connected in this order.

Thus, when coating the conductor 200 in the powder coating line, the hanger body, the upper energizing member and the lower energizing member are in electrical contact, and the powder paint is not attached to the insulating member, and the powder paint is applied only to the conductor 200. It is attached, and if necessary, the upper and lower conductive members can be easily removed from the hanger body and replaced, or they can be reused repeatedly after washing.

In addition, by minimizing the attachment of the powder paint to the hanger 130 by the insulating member on which the conductor 200 is mounted, power failure due to repeated use can be prevented, thereby minimizing coating defects.

Here, an insulating coating is formed on the outer surface of the straight hanger body, an insulating tape is formed, or an insulating tube is formed to have insulation.

Next, the booth forms a sealed space of the conductor 200 entering the powder coating line and sprays the powder coating to powder coating.

Specifically, the booth includes a base 141 formed on the bottom of the first rail 141a disposed in a direction perpendicular to the transfer direction of the hanger 130 by the transfer rail 110, and the first rail of the base 141 A pair of opposing first moving members 142 sliding back and forth along (141a), and a second moving member formed on the first moving member 142 to face each other in the same direction as the direction of the first rail 141a ( 143), and a powder coating spray gun 144 for spraying the powder coating onto the conductor 200, and a plurality of powder coating spray guns 144 formed on the second moving member 143 and opposed to the inside. The vertically arranged spray gun guider 145 and a second rail formed in a vertical direction inside the spray gun guider 145 so that the powder paint spray gun 144 moves up and down according to the length of the conductor 200. Si) and, the case 146 formed in a vertical direction from both ends of the second moving member 143, and the center of the case 146 is opened to transfer the hook 120 through the transfer slide groove 147a, The first moving member 142 adjusts the distance between the interior space of the painting according to the front and rear sliding of the first moving member 142, but is folded in multiple stages at the top of the case 146 to seal the upper end of the case 146 according to the separation distance adjustment, the upper blocking member 147 ), and the inner space of the painting according to the sliding back and forth of the first moving member 142, but folded in multiple stages inside the second moving member 143 to seal the bottom of the case 146 according to the separation distance adjustment , Consisting of a lower blocking member 148.

For example, as shown in FIGS. 2 and 3, when the conductor 200 is a medium-large conductor (see FIG. 2) or a small conductor (see FIG. 3), depending on the internal space of the case 146, The upper blocking member 147 and the lower blocking member 148 are separated from each other toward the conductor 200 in the horizontal direction, but in order to block the outflow of the powder paint sprayed by the powder paint spray gun 144 , The upper blocking member 147 is folded in two stages while sealing the transfer slide groove 147a, so that the upper and lower widths of the case 146 are expanded and extended or contracted to decrease.

That is, according to the size and shape of the conductor 200, the size of the inner space of the case 146 is adjusted while adjusting the separation distance of the injection gun guider 145, and according to the size and shape of the conductor 200 , By adjusting the spray height of the powder paint spray gun 144, it is possible to change the booth to enable small quantity production of multi-species.

On the other hand, the case 146, the top blocking member 147 and the bottom blocking member 148 are made of an uninterruptible acrylic or PVC non-conductor, so that the powder coating is not applied to areas other than the conductor 200.

Although not shown, the injection gun guider 145 includes a distance sensor (not shown) and a length sensor (not shown) for sensing the distance from the conductor 200 and the length of the conductor 200, respectively, A first driving unit (not shown) for sliding the first moving member 142 back and forth on the first rail 141a according to the sensed separation distance, and a powder coating spray gun 144 on the second rail according to the sensed length. It may include a second driving unit (not shown) for lifting and sliding.

For example, a wheel (not shown) formed at the lower end of the first moving member 142 and guided by the first rail 141a, a driving motor (not shown) for driving the wheel, and detected by a distance sensor Consisting of a control unit (not shown) that drives a driving motor according to the separation distance, or a cylinder rod (not shown) that slides the first moving member 142 back and forth along the first rail (141a), and drives the cylinder rod. Consisting of a hydraulic/pneumatic cylinder (not shown) and a control unit (not shown) that drives the cylinder according to the separation distance sensed by the distance sensor, the conductor is transported by the hanger 130 without manual manipulation of the operator. It is also possible to automatically perform the optimized powder coating of the conductor 200 by detecting the size and shape of the 200.

Alternatively, according to the length sensed by the slider (not shown) fixedly formed by sliding the powder paint spray gun 144 along the second rail, the hydraulic/pneumatic cylinder (not shown) for raising and lowering the slider, and a length sensor Including a control unit (not shown) that controls the lifting height of the slider by driving the cylinder, by detecting the length of the conductor 200 transported by the hanger 130, the optimized powder coating of the conductor 200 is performed. It can be done automatically.

Alternatively, if necessary or in case of an abnormality in automatic powder coating, the separation distance of the first moving member 142 is manually operated by the first rail (141a) and the wheel, or the height of the slider is manually operated by a manual control unit (not shown). It can also be adjusted manually by

On the other hand, although not shown, at the bottom of the case 146, after being sprayed by the powder coating gun 144, a vacuum module (not shown) that absorbs the remaining powder paint dropped on the bottom surface is configured to The powder paint remaining in the inner space of the case 146 by falling without being attached to the 200 may be recovered and recycled.

In addition, in response to the size and shape of the conductor detected by the distance detection sensor and the length detection sensor, the controller recognizes the conductor 200 and adjusts the injection amount sprayed to the powder coating spray gun 144, It is also possible to perform the powder coating of 200 uniformly and quickly, and to achieve the optimum amount of powder coating sprayed from the powder coating spray gun 144.

Therefore, by the configuration of the variable powder coating booth capable of producing a small amount of various kinds as described above, the movement of the powder coating gun and the internal space of the booth can be varied according to the shape and size of the conductor during powder coating work. In addition, it is possible to paint a small amount of various kinds and to efficiently operate a large amount of dedicated line.
