Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to a centrifuge after being separated by a centrifuge after being locked by a hand of a carrier and loaded into a rotary tank of a centrifuge from above. The present invention relates to the structure of the cage that is again locked by the hand and carried out from the centrifuge.

2. Description of the Related Art Conventionally, electronic parts and mechanical parts are
Since dirt such as oil adheres during the manufacturing process, the manufacturing plant is provided with a cleaning device for removing dirt such as oil from the manufactured product. This type of cleaning device is configured to clean parts with a cleaning liquid in a cleaning tank and then rinse them.
Since these parts are generally small in size, they are placed in a cleaning basket (see FIG. 5) in which wires are assembled in a grid pattern so that a plurality of parts can be cleaned and rinsed at once. Handles 100 and 101 are provided at two positions facing each other in this washing basket.

Since the cleaning liquid and the rinsing liquid adhere to the cleaned parts, a drying device for removing the cleaning liquid and the rinsing liquid is provided. As a drying device of this type, a centrifugal drying machine is known, such as a dehydrator of a washing machine, which centrifuges a cleaning liquid and a rinsing liquid from a part as an object to be cleaned. Also in the centrifugal dryer, the rotating tank of the centrifugal dryer contains a cleaning basket and is configured to rotate the cleaning basket inside thereof so as to separate the cleaning liquid and the rinsing liquid from a plurality of parts at once. There is. This centrifugal separator / dryer has a simple structure capable of simply switching between rotation and stop of the rotary tub, like the dehydration tub of a general washing machine.

[0004]

However, since the cleaning basket contains parts and is heavy, it is difficult to move the cleaning basket into and out of the cleaning tank and the rotating tank, and to move the cleaning basket from the cleaning tank to the rotating tank. This is a very burdensome work for the operator. Therefore, in order to save the labor of the work, it is supposed to provide a transfer device having a robot hand.
Further, this type of robot hand is configured to lock the handles 100 and 101 with respect to the cleaning basket in a predetermined azimuth position around the axis of rotation of the rotary tank. .

However, the conventional centrifugal dryer does not control the stop angle of the rotary tank as described above, and the azimuth position of the cleaning basket may change every time the rotary tank is stopped.
Therefore, depending on the stop angle of the rotary tank, if the cleaning basket is in an orientation position different from the predetermined orientation position, the robot hand may not be able to lock the handle and the cleaning basket may not be taken out from the rotation tank.

For that case, the conventional centrifuge dryer is modified to control the rotation angle when stopped, and the conventional robot hand is modified to lock the washing basket in any orientation. This is troublesome and causes a rise in the cost of these devices. In addition, there is a problem that manually fixing the cleaning basket in the rotary tank so as to face a predetermined azimuth position reduces work efficiency and hinders automation.

The present invention has been made to solve the above-mentioned problems, and a centrifuge using a hand of a transfer device is used regardless of the azimuth position of the cage centering on the axis of rotation of the rotary tank. The purpose of the present invention is to provide a basket that can be reliably transported from the container.

[0008]

In order to achieve this object, the structure of the basket carried by the carrying device of the present invention is
A basket main body that stores parts to which liquids to be separated are attached, and is provided above the basket main body, has a circular shape centering on the rotation axis of the rotary tank of the centrifuge, and is locked by a hand. It is composed of a locked portion.

[0009]

In the structure of the basket transported by the transport device of the present invention configured as described above, the locked portion is not affected regardless of the azimuth position of the cage around the axis of rotation of the rotary tank. ,
It is provided above the basket main body so that it can be locked by the hand of the transfer device.
