スタートとして必要とされるものである。(Problems to be Solved by the Invention) This electrodeposition coating is generally performed under the conditions of a paint concentration of about 20%, a paint temperature of about 25°C, a direct current pressure of 250 to 500V%, and a 280V duty. K to form a thick coating film on the surface of the object to be painted is, for example, about 180 seconds at a charging voltage of 280V. Needed. The first 10 seconds of the total energization time is required as a so-called soft start, which is a stage in which the charging voltage is increased to a predetermined voltage in order to prevent roughening of the painted surface.

In this case, the operation time of the drop lifter 21, such as horizontal travel and lifting and lowering, is added to the total energization time mentioned above, resulting in a long tact time of approximately 260 seconds (from the start of processing of one workpiece to the start of processing of the next workpiece).

できる。In this case, first, the first object to be painted 10 is placed in the paint tank 28!
! ffi and completely immersed, electricity is started to perform electrodeposition coating, and then, just before the next article 10 to be coated is placed in the tank, the electricity is cut off, and the next article 10 to be coated is completely submerged in the paint tank 28. After the energization is finished, the electricity is turned on again and the electrodeposition coating is continued until the predetermined coating thickness is reached (total energization time of 180 seconds/280V), and the coated object 10 is transferred to the conveyor. It is automatically and continuously carried out of the tank and transferred to the next process. By the way, in the example shown in Figure 10, the takt time was 120 seconds, but by shortening the hanger pitch (conveyor pitch) between the item to be coated and the next item to be coated, the takt time could be further reduced. It can also be shortened.
すなわち、スリッパ−ディップ式電着塗装装置は、タク
トタイムが著しく短く処理効率が大変高く、この点にお
いてバッチ式のものより有利なものであった。That is, the slipper-dip type electrodeposition coating apparatus has an extremely short takt time and a very high processing efficiency, and is more advantageous than the batch type in this respect.
しかし、パッチ式電着塗装装置は、小型の塗料槽で充分
足りるため、設置スペースが小さくかつ設備コストが安

式電着塗装装置は、設置スペース等の点においてスリッ
パ−ディップ式のものより有利なものであった。However, patch-type electrodeposition coating equipment requires only a small paint tank, so the installation space is small and equipment costs are low, whereas slipper-dip type electrodeposition coating equipment requires a very long paint tank. Therefore, a very large installation space and high equipment cost are required. Therefore, the batch type electrodeposition coating apparatus is more advantageous than the slipper-dip type in terms of installation space and the like.
本発明は、上記の実状を考慮してなされたもので、タク
トタイムがスリッパ−ディップ式のものと同程度に短く
できしかも設置スペースがバッチ式のもの並みに小さく
て済む全く新規な電着塗装装置を提供するものである。The present invention was made in consideration of the above-mentioned circumstances, and is a completely new electrodeposition coating that has a takt time as short as that of the slipper-dip type and requires less installation space than the batch type. It provides equipment.

特徴とするものである。That is, the apparatus of the present invention includes: an electrodeposition paint bath consisting of three sections: an entry area, a fully energized area, and an exit area; electrodes provided inside the bath in each of the areas; and each of the areas. A first power supply connected to the electrode and power supply in the tank entry area, a first power supply connected to the electrode and power supply in the fully immersed area, and an electrode and power supply in the exit area, respectively. A second power supply is connected to the tank, the lifter can be moved up and down, and the lifter can be moved horizontally, and the collector can be connected to the power supply. It is characterized by having a transfer mechanism which transports the liquid from the tank entry area to the fully energized area, from the fully immersed energized area to the tank outlet area, and then from the outlet area to the outside of the tank. be.

槽域に亘って一連として行なわれる。(Function) In the electrodeposition coating apparatus of the present invention, by operating the transfer mechanism, the article to be coated first enters the entry area of the paint tank from outside the tank, is then transported to the fully energized area, and then exits the tank. When in each of these areas, electricity is passed between the electrode, the object to be coated, the current collector, and the power supply to perform electrodeposition coating, and then the object is lifted out of the tank and transported to the next process. Electrodeposition coating in this case is energized separately from the two power sources, but as in the case of the slipper-dip method, it is performed in series over the tank entry area, fully energized area, and tank exit area. It will be done.

At the same time, the workpiece A to be painted is transferred to the outlet area of the paint tank, and the workpiece B to be painted is transported to the fully energized area of the paint tank, and then the workpiece Af
By repeating the operation procedure of lifting the product out of the f tank, two objects to be coated can be treated at the same time. Further, by making it possible to accommodate two or more objects to be coated in the fully energized area, three or more objects to be coated can be processed at the same time. Therefore, compared to patch type electrodeposition coating equipment,
Takt time can be significantly reduced.

By operating the transfer mechanism including
is carried from the previous process to above the entry area of the electrocoating paint tank 1 (position ■), then lowered and immersed in the paint tank 1 (position ■), and then passed through the first power source 4. Start energizing. Next, in Figure 1, after activating the DC interrupter 8 on the left side and connecting the power supply 3 in the tank entry area and the power supply 3 in the fully energized area to the same voltage, the article 10 to be coated is completely When the transfer is completed, the DC interrupter 8 is deactivated and the connection between the power supply devices 3 and 3 is cut off. During this time, the second power supply 5 is connected to the power supply 3 in the fully energized area.
energization is continued at a charging voltage of 300V via the At the same time, 1. When the article 10 to be coated is in the fully energized area, the next article 10 to be coated is carried above the entry area of the paint tank 10 (position ■), and then penetrated into the paint tank 1 (position @). Power supply via the first power source 4 is started. After that, both DC interrupters 8 are activated to connect all the power feeders 3 in each area to the same voltage, and while continuing to energize the article 10 to be coated, the area is changed from the fully energized area to the area where the tank comes out. At the same time as the work is transferred (position@), the next workpiece 10 to be coated is moved from the tank entry area to the fully energized area■),
After that, the operation of both DC interrupters 8 is stopped, and the article 10 to be coated is pulled up from the tank exit area to the outside of the tank (position ■).
, and then carried away to the next process. Furthermore, when the next object to be painted IQ is located in the fully energized region, the third object to be painted 10 is carried above the tank entry area of paint N1 (position ■) and then lowered to enter the tank 1 at medium pressure ( position ■) and start energizing.

Continue as in the case of painted article 10. Thereafter, the next article to be coated 10 is lifted out of the tank (position ■) and carried away to the next process. On the other hand, the arrival of the fourth article 10 to be coated is awaited. Thereafter, repeat the above steps.

することができる。(Effects of the Invention) As described above, the electrodeposition coating apparatus of the present invention has a structure in which a plurality of objects to be coated can be coated at the same time by applying electricity from two power sources in a paint tank consisting of three zones. Above all, takt time can be significantly shortened.
Therefore, it is possible to obtain coating processing efficiency comparable to that of the slipper-dip type apparatus, and to make the installation space and equipment cost very small and low as in the case of the batch type apparatus.
