Description

Coating equipment feeding system}

The present invention relates to a feeding system for coating equipment in painting equipment, and more specifically, the structure has been improved so that the movement/stop operation of the cart can be independently controlled by the operation of the docking member, so that a variety of products can be transported in large quantities using a single conveyor chain line. This relates to an object feeding system for painting equipment that enables production (painting) and, in particular, can improve painting quality by operating the brakes at the point when the bogie stops and accurately positioning the product at the designated position.

Typically, painting is a process of applying pigments to a surface to reproduce various colors, thereby improving marketability, and at the same time improving the performance of various painted materials by mixing functional materials such as antifouling and rust prevention into pigments.

In particular, as the lifespan of the object to be painted is shortened due to exposure to various contaminants and corrosion-causing substances, painting is used to increase the lifespan and at the same time improve the appearance with the color expressed in the pigment, thereby increasing the willingness to purchase. Because it relies on manual work, productivity is reduced, and because the pigment is sprayed in the form of fine particles, it seriously harms the health of workers.

Accordingly, in the previously disclosed registered patent No. 10-1894806, in the hanger transfer device for painting the underside of an automobile body that performs undersealing and undercoat processes for painting the underside of an automobile body, a hanger provided before and after the USB hanger carrying the car body High-speed power & free conveyor tracks that move trolleys at high speeds for undersealing; A low-speed chain conveyor track that is installed at the end of the high-speed power & free conveyor track and moves at low speed when the hanger trolley of the USB hanger loaded with the car body is moved from the high-speed power & free conveyor track to perform operator processing and undercoat processing; An inertia relief device that is installed at the entrance of the low-speed chain conveyor track and absorbs the inertial force of the hanger trolley of the USB hanger that has been moved quickly on the high-speed power & free conveyor track, reducing the entry speed of the USB hanger and preventing collisions with the car body; A technology consisting of has been previously presented.

However, in the prior art, when the USB hanger carrying the car body enters the low-speed chain conveyor from the high-speed power & free conveyor track, the speed is relaxed to prevent the car body from colliding with the car body, but the moving speed of the USB hanger is reduced. Because the high-speed power & free conveyor track and the low-speed chain conveyor are placed separately for control, collisions due to speed differences occur. In particular, the movement and stopping operation of the USB hanger is controlled by the speed of the conveyor, so the cycle time is reduced on a single conveyor track. This resulted in the problem that multiple different step-by-step coating processes could not be performed in a complex manner.
