Description

[Detailed Description of the Invention] The present invention relates to a rotation device for rotating a storage container for surface treatment, which is sequentially transferred and surface treatment is applied to the objects to be surface treated, at an appropriate position and at a predetermined angle. .

In the surface treatment apparatus, the storage container is sequentially transported to a storage position for the object to be surface treated, a position for immersing the object in a liquid tank, a position for taking out the object to be surface treated, and the like. In this transfer process, for example, the entrance of the storage container may be placed on the right side to facilitate storage of the surface-treated objects, the entrance may be placed upward to prevent the surface-treated objects from falling, or It may be advantageous to locate the inlet above or to the left in relation to the removal position.

The purpose of the present invention is to provide a rotating device that is optimal for changing the angular position of such a storage container, and in which a plurality of locking pins are attached outwardly to two corresponding sides of the storage container for surface-treated objects. The upper opening hooks on which the pins are placed are rotatably supported in the same number and in the same corresponding positions on a support plate that protrudes and rotates around a support shaft that projects horizontally from the lifting device. A rotating gear is fixed to the rotating shaft of the hook, and a fixed gear is fixed to the lifting device at a position concentric with the support shaft of the support plate, and the rotating gear and the fixed gear are connected via an intermediate gear. When the storage container with the locking pin mounted on the hook rotates as the support plate rotates, the hook rotates in the opposite direction at a constant angular velocity.

Rectangular substrates 15, 15 are attached to the lifting devices 14, 14, and support shafts 16, 16 are horizontally protruded inward from the center thereof.

In Figures 3 and 4, 20 is the lifting device 1 on both sides.
4 and 14, the two plates 21 and 21 are connected with a gap between them to form a support plate 22, and the support shaft 16 is inserted approximately through the center of the support plate 22. The support shaft 16 can be rotated around the support shaft 16. In the gap between the support plates 22, there is a support shaft 1.
A fixed gear 23 is provided externally and fixed to the support shaft 16, and rotary shafts 24 and 25 are inserted through the support plate 22 at separate positions on both sides of the support shaft 16, with their ends slightly protruding from the inner surface of the support plate 22. , rotary gears 26 and 27 are externally fitted and fixed to the respective rotary shafts 24 and 25 within the gaps. As a result, the fixed gear 23 is fixed to the lifting device 14 side, and the rotating shafts 24 and 25 are fixed to the support plate 22.
It is rotatably supported. In addition, the support shaft 16

As shown in FIG. 5, 42 is a rectangular parallelepiped-shaped storage container for surfaces to be treated, which has an opening 43 on one side and a shelf 45 inside. The length of the hook 3 is slightly smaller than that of the hook 3.
Locking pins 44, 4 at the same corresponding positions as 8, 38
Achieve 4. The locking pins 44, 44 are supported by bearings and can freely rotate.

The operation of the above embodiment will be explained.

As shown in FIG. 6, the storage container 42 is mounted on a pedestal 50 with the opening 43 positioned on the right side, for example.
Move the carrier 7 above the lifting motor 10.
by driving the rotation devices 20, 20 to the hanging columns 11, 1.
1 to position A, and then move forward slightly to position B, positioning the hooks 38, 38 directly below the locking pins 44, 44. When this is raised, the locking pins 44, 44 are mounted on the hooks 38, 38, as shown in FIG.

After this, the carrier 7 is advanced by the traveling motor 9, and at the next position, for example, in the case where the surface treatment object 46 is to be removed from above from the viewpoint of efficient use of the installation space of the various devices, the rotating cylinder 33 is rotated to move the opening 43 upward at that position.
Change the air supply direction of the cylinder rod 3.
3, and rotates outward around the fixed gear 23, causing the shaft 30 to rotate counterclockwise about the support shaft 16, with the support plate 22 rotating in response. When the support plate 22 rotates 90 degrees, this is detected by a limit switch or the like, and the air supply to the rotary cylinder is stopped, causing the rotation to stop, as shown by the chain line in FIG. 3. As the support plate 22 rotates 90 degrees, the storage container 42 placed on the hooks 38, 38 is driven, and its opening 43 is positioned upward, enabling the surface treatment object 46 to be removed (FIG. 8).
At this time, the rotary gear 26 rotates in the direction of the intermediate gear 29.
The rotating gear 27 is engaged with the fixed gear 23 via the gear 27 and rotates at the same angular velocity as the rotation of the support plate 22 about the support shaft 16 in the opposite direction.
The hooks 38, 38 supporting the locking pins 44, 44 are engaged with the fixed gear 23 through the intermediate gear 31, and rotate at the same angular velocity as the rotation of the support plate 22 about the support shaft 16, but in the opposite direction.
Since the support plate 38 rotates in the opposite direction to the support plate 22 at the same angular velocity, the open portion is always located at the upper position, and the support of the locking pins 44, 44 is constantly maintained.
At this time, the locking pins 44, 44 are freely rotatable, so that the locking pins 44, 44 are engaged with the hooks 38,
The hooks 38, 38 and the locking pins 44, 44 rotate smoothly relative to each other.

Although the rotation device 20 is used in the case where the object to be surface treated 46 is supplied from the right side and taken out from above, it can be applied to various other cases where it is necessary to change the angle. Moreover, the rotation of the support plate 22 is
This does not necessarily have to be done by rotating the intermediate gear 31; for example, by making the support shaft 16 freely rotatable with respect to the lifting device 14 and the fixed gear 23, and by solidifying the support shaft 16 and the support plate 22, the support shaft 16 is rotated. 16 may be rotated by a motor fixed to the lifting device 14 side. Furthermore, the rotation angle of the support plate 22 can be set arbitrarily.

As shown by the chain line in FIG.
Support plates 60, 6 are placed inside the processing liquid tank 2 from the inside of 4.
0 hangs down, a support shaft 16a protrudes inward from the support plate, and rotation devices 20a, 20a are provided thereon, thereby suspending the lifting columns 11, 11 of the lifting devices 14, 14.
The storage container 42 can also be immersed in the processing liquid tank 2 as it is lowered using the guide. In this case, by driving the rotating devices 20a, 20a to rotate reciprocally several times on the liquid tank 2, it can also be used as a liquid draining device for dropping the processing liquid in the storage container 42.

The rotating device 20 may be provided separately from the carrier 7, and the transport and reversal of the storage container 42 may be performed by separate mechanisms.

As clarified from the above description, the present invention includes a plurality of locking pins 44 protruding outward from two corresponding sides of the storage container 42, and a lifting device 22.
The upper opening hooks 38 on which the pins 44 are placed can be rotated in the same number and in the same corresponding positions on support plates 22 and 22 that rotate around support shafts 16 that are horizontally protruding from 0 and 20. The locking pin 4
4 to the hook 38, the storage container 42 is removably supported by the rotation devices 20, 20 from both sides thereof, and when the storage container 42 rotates as the support plates 22, 22 rotate, Since the hook 38 is configured to rotate in the opposite direction at a constant angular velocity, the storage container 42 can be rotated to any angle at any desired position without falling off the hook 38 during the transfer process of the object to be surface treated 46. Therefore, it is not necessary to install the various devices in a line, and for example, the surface-treated material 46 can be supplied from the horizontal direction and taken out from the vertical direction, which can correspond to the processing process and harmonize with the installation environment. It is possible to have an optimal layout of various devices, and furthermore, there are excellent effects such as the ability to invert the storage container 42 and to drain and swing the container 42 using the same device.
