Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a rotation for accommodating an object to be treated in a container-shaped barrel and performing a predetermined treatment such as dipping and liquid-drying while rotating the barrel. Regarding the barrel device.

(Prior Art) This type of rotary barrel device has conventionally been used for dipping treatment of an object to be treated (hereinafter referred to as a work), for example, by dipping adhesive on the surface of the work, applying a paint, or degreasing the work. It is widely used for dipping and degreasing cleaning, or for draining and drying a dip-treated work.

FIG. 3 shows an example of a rotary barrel device of this type that has been conventionally generally used. As shown in the figure, this barrel device is provided with a barrel 100 having a hexagonal tubular shape, and while the work is accommodated in the barrel 100, a part of the work is immersed in the liquid agent 102 and rotated, thereby rotating the work surface. The liquid agent 102 is applied to or is degreased and washed.

In this barrel device, one surface of the outer peripheral surface around the axis of the barrel 100 having a hexagonal tubular shape has an opening shape, and the opening shape portion is opened and closed by the lid 104,
After opening the lid 104, the work is put into the barrel through the opening, and the processed work is taken out.

However, in the case of this barrel device, since the operator manually opens and closes the lid 104, there is a problem that it is difficult to automate the processing process by the barrel.

(Means for Solving the Problem) The device of the present invention has been devised to solve such a problem, and its gist is: (a) a tubular shape whose both axial ends are open. A barrel, (b) a support for supporting the barrel in a lying state, (c) a lid for closing an opening shape portion on one end side of the barrel, and (d) provided on the support, A lid opening / closing mechanism for holding the lid and moving the lid between a position for closing the open shape part and a position for opening the open shape part; and (e) provided on the support body to move the barrel around its axis. A rotary drive means for rotationally driving,
(F) An opening that is opened / closed by the lid, with the support, the barrel and the lid opening / closing mechanism supported by the support, the rotation driving means, and the axial center of the barrel tilted at a predetermined angle with respect to the horizontal direction. Inclination means for inclining the shaped portion in the direction of being on the lower side.

(Operation and Effect of the Invention) In the apparatus of the present invention, the barrel is preliminarily tilted together with the support, and the workpiece to be treated is loaded into the barrel from one open end of the barrel which is upward to some extent. can do. Thus, after the work is loaded, the barrel drive is rotated by the rotary drive device while maintaining the tilted state, whereby the work in the barrel can be subjected to the dipping process and other processes. At this time, since the downward open end of the barrel can be kept closed by the lid, the work inside the barrel does not fall from the downward open end. At this time, one open end is still open, but since this open end faces upward, the work inside the barrel does not come out from there.

Now, when the barrel is rotated in an inclined state and the processing on the work is finished, the lid is then opened by the opening / closing mechanism,
Since the barrel is inclined, the internal work is dropped and discharged to the outside from the opened downward end of the work.

As described above, in the apparatus of the present invention, the lid body is not provided on the barrel itself, the lid body is separately arranged, and the lid opening / closing mechanism moves the lid body to close the open end of the barrel. It was done.

Therefore, it is not necessary for an operator to open and close the lid for loading or unloading the work into the barrel, and therefore, the processing of the work by the barrel can be automated.

Further, since the barrel is rotated in a tilted state, it is not necessary to separately close another open end portion where the lid body is not arranged, and the structure of the barrel device is simplified accordingly. Further, when the barrel is rotated and the processing for the work is finished, the work inside the barrel can be discharged simply by opening the lid, so that the work can be performed efficiently without waste of movement.

(Example) Next, the Example of this invention is described in detail based on drawing.

In FIGS. 1 and 2, reference numeral 10 denotes a barrel, which has a cylindrical shape with both ends open as a whole. The barrel 10 has a form in which ring-shaped frames 12 at both ends are connected by a plurality of tie bars 14, and a pair of ring-shaped rails 16 are fixedly mounted on the tie bars 14 at predetermined intervals. These rails 16 are rotatably supported from below by the support rollers in a state of being fitted into the grooves of the plurality of support rollers 18.

As shown in FIG. 1, each support roller 18 is connected to a motor 23 via a sprocket 20 and a chain 22, and is rotated by the motor 23. That is, the barrel 10 is rotationally driven via the rail 16 by the rotation of the motor 23.

The support roller 18 and the motor 23 are supported by a support body 24 arranged below the barrel 10. An arm 26 stands up from one end of the support 24, and at the upper end thereof,
A shooter 28 having a U-shaped cross section for loading a work into the barrel 10 is provided.

Another arm 30 extends upward from the other end of the support 24, and an opening / closing cylinder 34 of a lid 32 that closes an open end of the barrel 10 is attached to the arm 30.

The lid body 32 is held by a holding body 36, and the upper end portion of the holding body 36 is rotatable about a shaft 38.
An arm 40 integrally extends from the shaft 38, and the arm 40 is connected to the cylinder 34. Therefore, when the cylinder 34 operates in the contracting direction, the arm 40 is rotated in the clockwise direction, and the shaft 38 is rotated in the same direction, and the holding body 36 and the lid body 32 are both in the clockwise direction, that is, the open end of the barrel 10. It can be rotated in the direction to open the part. Conversely, when the cylinder 34 operates in the extension direction, the arm 40, the shaft 38, the holding body 36, and the lid body 32 are rotated counterclockwise, and the barrel
10 open ends are closed.

The support 24 is rotatably supported by a base 46 arranged below the support 24 via a bracket 42 and a shaft 44. Further, the support body 24 has a cylinder 48 for inclining the support body 24, which is connected via a bracket 50.
The actuation of 48 causes the entire barrel 10 to be tilted with the support 24 and also returned horizontally.

The base 46 is horizontally movable by the rollers 52 and the guide rails 54.

56 is a tray for receiving the liquid adhering to the work.

Next, the operation of this device will be described.

As described above, when the cylinder 48 operates in the contracting direction, the barrel 10 is rotated in the counterclockwise direction in FIG.
In this state, a work to be subjected to a predetermined process is loaded from the bucket 58 into the barrel 10 through the shooter 28.
At this time, the lid 32 is in a closed state.

When the motor 23 operates in this state, the rotation of the support roller 18 causes the barrel 10 to rotate while maintaining the inclined state,
The work housed inside is subjected to a predetermined treatment (here, a drying treatment of the liquid used for the dip treatment in the previous step) while being rolled and stirred inside the barrel.

After a lapse of a predetermined time, the cylinder 34 closes the lid.
32 is opened, and the work inside the barrel 10 is dropped and discharged here.

As described above, according to the apparatus of this example, the lid can be automatically opened and closed, so that the worker can insert the work into the barrel 10 and discharge it from the barrel 10 by the operator. It is not necessary to open and close the body.

Further, in the case of the barrel device of this example, since one opening of the barrel 10 is held in an open state, it is not necessary to open the lid body when loading a work piece, and in addition, when the work piece is discharged, simply opening the lid body piece does not change the shape. Since the work inside the barrel is dropped and discharged to the outside due to its own weight, there is no waste in operation, and work can be performed smoothly and efficiently.

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