Abstract

PURPOSE: To provide a basket rotating device for a surface treating device which is capable of supporting both sides of a barrel by means of bearings and eliminates the possibility of jumping of the basket out of the inside of this barrel even when the barrel is rotated. CONSTITUTION: A basket housing section 7 to be inserted with the basket 9 from a direction perpendicular to the revolving shaft of the rotated barrel 1 is formed in this barrel. The basket 9 in which works are housed is set in the basket housing section 7 and is rotated together with the barrel 1, by which the works are subjected to a surface treatment. The aperture 8 of the basket housing part 7 is provided with a main stopper 10 for preventing the jumping out of the basket 9 and an auxiliary stopper 20 for locking the main stopper 10 to prevent the jumping out of the basket 9 under rotation.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basket rotating device in a surface treatment device.

[0002]

2. Description of the Related Art A basket containing a relatively small work is set in a cylindrical barrel which is rotated in a tank, and a surface treatment such as cleaning or chemical conversion treatment is carried out. The rotating device is conventionally known, for example, from Japanese Utility Model Publication No. 1-28863. In such a conventional basket rotating device, since the basket is inserted from the end surface of the cylindrical barrel in the direction of the rotation axis, when the barrel is rotated around the horizontal rotation axis, the basket is gravitationally moved by gravity. There is no danger of jumping out of. However, in such a conventional basket rotating device, since the basket is taken in and out from the end surface of the barrel, it is not possible to support both sides of the barrel by bearings, and it is special that the outer peripheral surface of the barrel is supported by a plurality of rollers. There was a problem that we had to take a structure.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art and allows both sides of the barrel to be supported by bearings, and there is no risk of the basket popping out even when the barrel is rotated. The purpose is to provide a basket rotating device in a surface treatment device.

[0004]

A basket rotating device in a surface treatment apparatus of the present invention made to solve the above-mentioned problems is provided in a barrel rotated in a surface treatment tank, with respect to its rotation axis. A basket storage part for inserting the basket from the vertical direction is formed, and a main stopper for preventing the basket stored in the basket storage part from popping out is locked in the opening of the basket storage part and the movement of the main stopper is locked. It is characterized in that an auxiliary stopper is attached.

[0005]

According to a preferred embodiment of the invention, the barrel is supported on both sides by bearings and is rotated about a horizontal axis of rotation. Then, the basket in which the work is stored is inserted into the basket storage portion inside the barrel through the opening in the direction perpendicular to the rotation axis of the barrel. The main stopper provided at the opening of the basket storage unit prevents the basket from popping out, and the auxiliary stopper locks the movement of the main stopper. For this reason, even if the opening of the basket storage section faces downward while the barrel is rotated around the horizontal rotation axis, the main stopper will not come off due to the gravity of the basket, and the basket will be reliably prevented from popping out. can do. If the main stopper and the auxiliary stopper can be opened and closed from the outside by an air cylinder or the like, the whole movement can be automated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the illustrated embodiments. In FIG. 1, reference numeral 1 is a cylindrical barrel that is rotated in a surface treatment tank, and both sides thereof have vertical arms 2
Is rotatably supported by a bearing 3 at the lower end of the. A spur gear 4 is provided on the outer peripheral portion of the barrel 1, and the spur gear 4 is driven by a drive gear 6 via an intermediate gear 5.
The barrel 1 can be rotated around a horizontal axis of rotation that connects the bearings 3,3.

As shown in FIG. 1, a basket storage portion 7 is formed inside the barrel 1. In this basket storage portion 7, a basket 9 can be inserted through an opening 8 provided in a direction perpendicular to the rotation axis of the barrel 1. The basket 9 is a basket-like body with a lid that can store small workpieces.
At the same time, the structure allows the surface treatment liquid to pass freely.

The opening 8 of the basket storage portion 7 is provided with a main stopper 10 and an auxiliary stopper 20 as shown enlarged in FIGS. The main stopper 10 is an L-shaped hook 12 rotatably and pivotally mounted on a bearing 11 provided on the barrel 1. The main stopper 10 is provided with an opening / closing lever 13 at one end, and by pressing the opening / closing lever 13 with an air cylinder or the like as will be described later, L
The structure is such that the character-shaped hook 12 can be opened to the outside.

The auxiliary stopper 20 is provided outside the main stopper 10, and has a stopper piece 21 that locks the outward opening of the L-shaped hook 12. Stopper piece 21
Is equipped with a slide shaft 22, and a spring seat is mounted on the slide shaft 22.
23 are fixed. The stopper piece 21 is moved to the position shown in FIG. 2 by the spring 25 provided between the fixing tool 24 and the spring receiving seat 23.
It has repulsed to the position of (the position where the main stopper 10 can be locked).

In the basket rotating device described above, a basket 9 accommodating a small work is inserted into the basket accommodating portion 7 inside the barrel 1, the whole is immersed in the surface treatment tank, and the barrel 1 is rotated by the drive gear 6. Then, the surface treatment is performed. During this rotation, the opening 8 of the basket storage portion 7 may face downward, but the main stopper 10 prevents the basket 9 from popping out, and this main stopper
Since the opening of 10 is also locked by the stopper piece 21 of the auxiliary stopper 20, the basket 9 does not fall off.

When the basket 9 is put in or taken out of the basket storage portion 7 before and after the surface treatment, first, the stopper piece 21 of the auxiliary stopper 20 is moved rightward in FIG. 4 by the auxiliary stopper cylinder 30 as shown in FIG. Press. Then, as shown in FIG. 5, the stopper piece 21 is attached to the L-shaped hook 12 of the main stopper 10.
After moving to a position where the lock can be released, the opening / closing lever 13 of the main stopper 10 is pressed rightward in the drawing by the main stopper cylinder 31. This makes the L-shaped hook 12
Opens to the outside, and the basket 9 can be freely put in and taken out of the basket storage portion 7.

[0012]

As described above, the basket rotating device in the surface treating apparatus of the present invention has the basket storing portion for inserting the basket from the direction perpendicular to the rotation axis of the barrel. Both sides of the barrel may be supported by bearings. Moreover, since the main stopper that prevents the basket stored in the basket storage portion from popping out and the auxiliary stopper that locks the movement of the main stopper are attached to the opening of the basket storage portion, the basket can be rotated even when the barrel is rotated. There is an advantage that it can be surely prevented from jumping out by its own weight.
