Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a paint dryer that serializes the cleaning process, painting process, and drying process, making it possible to paint and dry in a short time. .

(Prior Art) Conventionally, a cleaning process for cleaning parts to be painted and a process for painting and drying have been performed using independent and separate equipment. For this reason, painted parts are heated to 60° to 70°C during cleaning, and then painted after being completely cooled, then heated again and dried.

(Problem that the invention aims to solve) In this way, the painted parts are completely cooled before the painting process, so even if you try to heat them with a heater after painting and dry them, drying is not possible due to the short cycle time required for
In the next process, there were problems such as adhesion of the paint to the outside and peeling of the paint from the areas where the paint was applied.

In order to prevent such problems from occurring, it is necessary to reduce the amount of time required to move the parts from the parts station in the washer after cleaning to the painting spot in the sprayer, and from the painting spot to the drying spot in the dryer. It is best to shorten the time as much as possible. The present invention was developed in view of this point.

(Means for Solving the Problems) The present invention, as a means for solving the above problems, provides a coating apparatus having a washing machine, a coating machine, and a dryer. In the apparatus, between the parts station 2 of the washing machine 1 and the coating spot 3 of the coating machine, and between the coating spot 3 and the drying spot 1 of the dryer,
0, there are provided first and second reversing chutes 7, 12 each forming a U-shape and having forks 7a, 12a formed at one end, the first and second reversing chutes 7, 12 A part thereof is supported by horizontal fixed shafts 8 and 13 in a freely reversible manner.

(Function) With this configuration, parts can be removed between the parts station 2 of the washing machine 1 and the coating spot 3 of the coating machine, and between the coating spot 3 and the drying spot 10 of the dryer. 6 can be quickly and reliably moved by reversing the first and second reversing chute 7, 13, and by forming it into a U-shape, the movement of 60 to Part 6, whose temperature has risen to 70°C, is painted and dried before it cools down, so the part temperature rises even for a short period of time during the drying process, allowing for sufficient drying. .

(Example) Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a parts chute 4 directly connects a parts station 2 at the end of cleaning of a washing machine 1 in a cleaning process to a painting spot 3 in the next painting process. A coating nozzle 5a of a coating machine 5 is located close to the coating spot 3, and paint is sprayed from the coating nozzle 5a onto the lower part of the component 6 above the coating spot 3. In the painting spot 3, the part 6 is then placed in the first part in the shape of a rectangular shape with a concave portion at the top.
Fork 7a provided at the tip of the reversing chute 7
is inserted into. The first reversing chute 7 rotates around a horizontal fixed shaft 8 that supports a part of it, and reaches a position indicated by an imaginary line 7', and a small chute 9 is located at that position. is directly connected to the drying spot 10 in the next drying process. Paint spot 3 and dry spot 1
0 are connected by a first inverted chute 7 and a small chute 9. In addition, in the drying spot 10, a heater 11 is installed to heat the part (part 6' shown in the imaginary line).
, and the part 6 on the drying spot 10 is
It also has a bent-back shape, and is fitted into a fork 12a provided at the tip of the second reversing chute 12, which has a recess at the top. The second reversing chute 12 is supported by a horizontal fixed shaft 13,
It is designed to rotate to a position indicated by an imaginary line 12'.

When the painted parts 6 reach the parts station 2 at the end of cleaning of the cleaning machine 1, the cleaning process has been completed, so they are immediately placed on the parts chute 4, transported to the painting spot 3, and then transferred to the first painting spot 3. It is inserted into the fork 7a of the reversing chute 7 (see FIG. 2). When the part 6 reaches the paint spot 3,
A detection device (not shown) is activated, and the coating machine 5 starts operating, and paint is sprayed from the coating nozzle 5a toward the component. The sprayer 5 stops spraying using a timer, and the first rotary chute 7 rotates in response to a signal to stop spraying. The part 6 rotates while being inserted into the fork 7a and reaches the small chute 9, where it moves on the small chute 9 and reaches the drying spot 10. In the drying spot 10 the part 6' is transferred to the second reversing chute 1, as in the case of the painting spot 3.
The second fork 12a is inserted into the second fork 12a. If such a condition occurs, a detection device (not shown) will operate, the heater 11 will start, drying will begin, and after the drying time set by the timer has elapsed, the second reversing chute 12 will rotate to move the parts to the next one. Send it to the process.

In this case, the parts are washed in washing machine 1.
Heated to 60°-70°C. Therefore, it is transported to the next chute 4 at that temperature, painted, and then transferred to the first chute 4.
It is transported to a drying spot by a reversing chute 7 and a small chute 9. Due to the rapid reversing operation of the first reversing chute 7, it takes only a few seconds for the parts 6 to move from the time they leave the washer to the drying spot, so that the parts reach the drying spot with little cooling. Therefore, if the paint is heated by the heater 11 for about ten seconds, the temperature will rise and the paint will be sufficiently dried, and the paint will not stick to the outside or peel off.

(Effects of the invention) The present invention has the above-mentioned configuration, and by operating the first and second reversing chute that reliably grips the parts and quickly reverses them, the painted parts can be dried in a short time. Once the process is complete, painting can be done in a short cycle time, which improves productivity. Furthermore, since drying is insufficient at the end of painting, the paint will not adhere to other surfaces or peel off in the next process. Furthermore, since the drying time is shortened, many effects such as energy saving are expected.
