物を置かないようにしている。(Problems to be Solved by the Invention) Generally, in this type of equipment, if a work is left in a washing tank or an electrodeposition tank at the time of a break in the daytime or at the end of work, rust occurs or paint is applied. At the time of a break or at the end of work, no work is placed on the pre-treatment coating line from the place where defective products are made by passing.

も30分前には加工物を前処理塗装装置に入れないように
しており、例えば１日の装置の稼働時間を８時間とする
と、そのうちの１時間は装置が空動きすることになり、
稼働率が低下している。By the way, in the above-mentioned conventional equipment, it takes about 30 minutes for the workpiece to pass through the pretreatment coating apparatus, but the transport conveyor has a first transfer position on the starting point side and a second transfer position on the front side of the drying furnace. There is no space between the transfer position and the fixed number of carrier bars with hangers returned from the end point, and as soon as the first transfer operation of the carrier bars is completed, the hooks are connected to the drying furnace outlet side. The work is not put into the pre-treatment coating equipment at least 30 minutes before a break or at the end of the work because it is sent to the transfer position of No.2. If the time is 8 hours, the device will idle for 1 hour,
Occupancy rate is decreasing.
そこで、この発明は塗装設備における加工物の搬送装

しうるようにしたことを特徴とするものである。(Means for Solving the Problems) In order to achieve the above object, an elevating bar consisting of a plurality of pretreatment tanks and an electrodeposition tank in series and comprising a guide rod and a slide rod along the longitudinal direction is provided at an upper portion thereof. A pre-treatment coating device and a drying furnace are provided in two stages, and a first coating is provided at the front of the entrance of the pre-treatment coating device and at the front of the exit of the drying furnace.
Alternatively, a second transfer trolley is provided, a transport conveyor is stretched around the periphery between the pretreatment coating device and the drying furnace, and a workpiece is provided in front of the entrance of the pretreatment coating device along the transport conveyor. A first transfer position and a first transfer position are provided, and a second transfer position is provided in front of the outlet of the drying furnace. In the first transfer position, the carrier bar with the workpiece before painting is placed in the first transfer position. As a transfer device of the coating equipment in which the carrier bar with the coated and dried workpiece is transferred to the transfer conveyor at the second transfer position at the second transfer position. Conveyor No. 1
Between the transfer position and the second transfer position, there is provided a bypass storage portion having a length capable of accommodating at least the same number of carrier bars as the carrier bars arranged in parallel with the pretreatment coating device, and a part of the frame is rotated. A driving device capable of switching directions is provided, and the driving device can reverse the transport conveyor when required.

先頭のものを終点まで戻す。(Operation) When the switch is pressed at the time of pausing or termination of the work and the stop and the removal of the work from the carrier bar are stopped, the first transfer trolley stops, and the carrier bar with the work is sent to the pretreatment coating apparatus. As a result, empty space is created in the device, where no workpieces exist.In the detour storage section of the transport conveyor, a carrier bar with empty hangers returning from the end point is accommodated, while painted and dried workpieces are installed. The carrier bar goes past the end point to the starting point side. When there is no more work in the pre-treatment coating equipment, the equipment temporarily stops, and after a short period of time, the transport conveyor is reversed by the drive device, and the leading one of the painted and dried work bar with work that has advanced to the starting point side is removed. Return to the end point.

ージ部13aを通って第２移し替え位置C2に移動する。With the above configuration, during normal work, the transport conveyor 13 is driven in the direction indicated by the solid arrow in the same manner as described above, and the starting point s and the empty bar h are hung by the hook f together with the carrier bar g.
At the starting point s, the workpiece w (for example, the body or cover of the air cleaner) is hung on the hanger h, and the carrier bar g with the workpiece before painting is moved to the first transfer position.
It is sent to a C 1. The first sorting position C 1 have been bogie 12 and transferred on call, by operating the cylinder member 12a, receives a carrier bar g with the workpiece from the hook f by receiving fixture 12b as in the second figure, the first Is moved immediately before the pre-treatment coating apparatus A. However, the hook f so far without immediately moves to the second sorting position C 2 as moved position to the C 2 second sorting through the detour storage unit 13a.
