In a rotating barrel device for subjecting an object to be processed to predetermined treatments such as dipping, draining, and drying, a rotating shaft body that rotates integrally with the barrel from each end face in the axial direction of the barrel is provided. While extending respectively, the rotation shaft is rotatably supported from below by rollers on both sides in the axial direction of the barrel,
In addition, one end of the rotary shaft body and one of the rotary drive members for rotationally driving the rotary shaft body are provided with an engagement groove, and the other is provided with an engagement projection portion so that they can be detachably engaged in a state of integrally rotating them. Thus, the end portion of the one rotating shaft body and the rotation driving member are connected to each other.

(Operation and Effect of the Invention) According to the present invention as described above, the rotation shaft body extended from the barrel is rotatably supported from the lower side, and the end portion of the rotation shaft body is detachable from the rotation drive member. According to the present invention, therefore, the connection between the rotary shaft and the rotary drive member can be easily released and the barrel can be easily removed alone.

Therefore, in the device of the present invention, when the barrel becomes dirty, it can be easily cleaned by removing it, and by replacing it with a new barrel, the operation of the barrel device is not stopped during the cleaning period. In addition, productivity can be improved.

 Next, the operation of this device will be described.

In this device, at the position (a) in FIG. 9 (work loading station), the barrel 10 has the partition plate 16 in a substantially vertical direction and the open shape portion 14 as shown in FIG. 8 (A).
Is held at an angle so as to face upward, and in this state, a predetermined work W is loaded into the barrel 10 from the open shape portion 14. When the work W is loaded into the barrel 10, the barrel 10 is horizontally moved from the position (a) in FIG. 9 to the position (dip station) in (b). The operation at this time is as follows. That is, the motor 36 shown in FIG. 6 is actuated to rotate and move the chain 28, so that the support body 18 connected to the chain 28 via the bracket 26 is horizontally guided under the guide of the guide rail 24 and the fitting portion 22. Slide to. At this time, the barrel 10 is moved in the horizontal direction together with the support main body 18. At this time, the pair of bevel gears 56, 58 for transmitting the rotational driving force from the motor 72 are maintained in mesh with each other. Horizontally moved with 18 and barrel 10. Because the first bevel gear 58 is a guide rail.
24 is slidably fitted along a spline shaft 62 extending in a direction parallel to 24, and the first bevel gear 58 and the second bevel gear 56 are integrally supported by the support bracket 40 in a state of maintaining a relative positional relationship. Because.

Now, when the barrel 10 moving together with the support body 18 reaches the dip station shown in FIG. 9B, the dip tank 82 is then raised by a lifting device (not shown),
The lower part of the barrel 10 is immersed in the dip solution. At the same time, the barrel 10 is rotated in the clockwise direction (forward direction) as shown in FIG. 8 (B), and the work W in the barrel is subjected to a dipping process. Specifically, the driving force from the motor 72 is generated by the spline shaft 62, the first and second bevel gears 58, 5
6, transmitted to the rotary shaft body 12 of the barrel 10 via the transmission shaft 44, whereby the barrel 10 is rotated in the clockwise direction (hereinafter referred to as the positive direction). Then, as shown in (C), the partition plate 16 hits the work W accumulated in the lower portion inside the barrel 10 at a certain position, and the partition plate 16 is blocked. After that, when the barrel 10 is further rotated, the work W is rotated (revolved) around the rotary shaft body 12 together with the partition plate 16, and when the partition plate 16 is rotated beyond the substantially horizontal position, the partition plate 16 is rotated. The work W placed on the plate 16 slides off the partition plate 16 as the barrel 10 rotates further (see (D)). At this time, the inner surface of the outer peripheral portion of the barrel is located. Accepted on top. When the barrel 10 is further rotated in the forward direction from this state, the work W is blocked by the rotating partition plate 16 and starts to rotate (revolve) together, and thereafter the same operation as described above is repeated.

As described above, the work W is subjected to the stirring action while repeating the revolution movement and the rotation movement around the rotary shaft 12 as the barrel 10 rotates, and the dip liquid is applied to the outer surface thereof. Alternatively, when the dipping solution is a cleaning solution, the surface is cleaned with such a cleaning solution.

In this way, the work W at the station (b)
When the dipping process is completed, the dip tank 82 is lowered, and then the barrel 10 is horizontally moved again from the position (b) to the draining and drying station (c). The operation at that time is similar to that described above.

When the barrel 10 reaches the station (c), hot air is blown from here, and the work W in the rotating barrel 10 is dried. Work W at this station (C)
When the drying of is completed, the barrel 10 is moved horizontally to the take-out station of (d), where the barrel 10 is in the opposite direction from the previous time, that is, as shown in (F) in FIG. Can be rotated in the direction. When this rotation causes the open shape portion 14 of the barrel 10 to face downward, the work W in the barrel 10 is dropped and discharged from the open shape portion 14 to the outside.

As described above, in the apparatus of this example, it is not necessary to open and close the lid when the work W is loaded into the barrel 10 and taken out of the barrel 10. Therefore, there is no need for an operator to open and close the lid, and the work can be automatically inserted and ejected. In addition, the equipment is different from the barrel device that automatically opens and closes the lid. The cost can be kept low.

Further, since the lid is not opened and closed, there is no problem of biting the work when the lid is closed. In addition, in the case of the barrel device of the present example, the work is revolved largely in the barrel while revolving in the barrel, so that the stirring effect on the work is also high.

In the device of this example, the barrel 10 (specifically, the rotary shaft body 12) is rotatably supported from below by a roller 42, and the barrel 10 has its rotation drive member (transmission shaft 4
Since it is detachably connected to 4), if the barrel 10 becomes dirty, it can be easily replaced with a new one. Therefore, the barrel 10 can be easily cleaned, and it is not necessary to stop the operation of the apparatus during the cleaning period.

Further, in the apparatus of this example, since the structure of the barrel 10 can be simplified, the barrel 10 can be independently slid horizontally in the horizontal direction by the slide moving means. It is possible to perform a plurality of processes such as cutting and drying, and this has the advantages that the working efficiency is improved and the equipment cost is low.

Although the embodiment of the present invention has been described in detail above, this is merely an example, and the present invention can be configured with various modifications based on the knowledge of those skilled in the art without departing from the spirit of the present invention. .
