Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an apparatus for transporting a basket containing workpieces and applying vibration to the basket as necessary, and is particularly suitable for a plating process. The present invention relates to a vibration conveyance device.

(Prior art) Conventionally, when plating small workpieces (workpieces), one of the processing methods is to store a large number of workpieces in a basket, transport the workpieces in that state, and immerse them in a processing solution. method has been adopted.

(Problems to be Solved by the Invention) However, in such a method, it is necessary to remove the processing liquid adhering to the basket or work each time one processing is completed. However, with conventional devices, there are problems in that it is difficult to drain the liquid sufficiently and it takes time to drain the liquid.

(Example) In order to solve the above-mentioned problems, the present invention provides a moving cart mechanism that moves horizontally above a plurality of processing tanks, attaches an elevating slider to the moving cart mechanism, attaches a movable base mechanism to the elevating slider, A vertical drive mechanism connects a holder that holds a basket containing a workpiece to the movable base, and causes the movable base to vibrate the holder up and down; and a rotational drive mechanism that causes the holder to vibrate in a rotational direction about a vertical axis at a predetermined angle. It is characterized by having the following.

(Function) According to the above configuration, the basket containing the work is held by the holder attached to the movable base, and when the movable trolley mechanism travels in this state, the basket is transported in the horizontal direction together with the elevating slider and the movable base. Further, when the elevating slider moves up and down, the basket is moved up and down together with the movable base.

On the other hand, when the vertical drive mechanism is activated, the basket or workpiece vibrates up and down, and when the rotational drive mechanism is activated, the basket or workpiece vibrates about the vertical axis.

(Example) Fig. 1 is a schematic vertical cross-sectional view of an embodiment of the present invention, Fig. 2 is a schematic view taken in the - arrow direction of Fig. 1, Fig. 3 is a - arrow view of Fig. 1, and Fig. 4 is a schematic view taken in the - arrow direction of Fig. 1. FIG.

In FIG. 2, reference numeral 1 denotes a basket made of a perforated plate with an open upper end, and although not shown, a large number of small works are housed inside. This basket 1 is transported by a transport device 2 and placed in various processing tanks 3 (only one is shown).

The conveyance device 2 includes a pair of horizontal rails 6 fixed to a frame 5 and a cart 8 that runs on the rails 6 by rollers 7. Rail 6 on trolley 8
A pair of rails 9 are provided which are orthogonal to each other, and another truck 10 of the transport device 2 runs on the rails 9. In order to make the carts 8 and 10 travel, a drive mechanism (not shown) consisting of a motor, a chain, etc. is connected to them. Further, the conveying device 2 is provided with a slider 11 that moves up and down with respect to the cart 10, a movable base 12 connected to the slider 11, a holder 13 attached to the movable base 12, and the like, and the holder 13 holds the basket 1. I'm starting to do that.

As shown in FIG. 3, the slider 11 is driven up and down by a chain mechanism 15. The upper end of a vertical column 17 for guiding the rollers 16 of the slider 11 is fixed to the truck 10, and a motor 18 for driving the chain mechanism 15 is mounted. The base end of a horizontal arm 20 is fixed to the slider 11,
The movable base 12 is connected to the tip of the arm 20 as follows.

As shown in FIG. 1, the lower end of a vertical air cylinder 21 is fixed to the arm 20, and a piston rod 2 protrudes downward from the air cylinder 21.
A movable base 12 is fixed to 2. A vertical shaft 2 is connected to the center of the movable base 12 via a bearing 25.
6 is rotatably supported, and the upper end of an air cylinder 31 perpendicular to the cover 30 of the holder 13 is fixed to the lower end of the shaft 26.

A piston rod 32 of the air cylinder 31 projects downward from the main body of the air cylinder 31, and its lower end is connected to a lever mechanism 33. The lever mechanism 33 is equipped with one or more hooks 35 at the lower end, and when the piston rod 32 is in the protruding state as shown by the solid line, the hooks 35 are inserted into the basket 1 and attached to the opening periphery 36 at the upper end of the basket 1. It can be engaged from below, and when the piston rod 32 is inserted, the hook 35 can be removed from the opening periphery 36 and moved above the basket 1, as shown by the two-dot chain line. ing.

The cover 30 extends to the vicinity of the hook 35, and when the hook 35 is engaged with the lower surface of the opening periphery 36, the lower end of the cover 30 touches the opening periphery 36.
It is designed to support the upper surface of 6. The cover 30 also supports the upper end of the lever mechanism 33 via a pin 37.

A movable base 1 is attached to the outer peripheral bracket of the shaft 26.
A piston rod 41 of an air cylinder 40 attached to 2 is connected. As shown in FIG. 4, which is a partial cross-sectional view of FIG. .

Next, the operation of the apparatus of the embodiment will be explained. By operating the air cylinder 40 and reciprocating the piston rod 41, the shaft 26 vibrates in the rotational direction at a constant angle, and the holder 13 and the basket 1 also vibrate in the rotational direction. Furthermore, by operating the air cylinder 21 and reciprocating the piston rod 22, the movable base 12 vibrates up and down, and the holder 13 and the basket 1 also vibrate up and down.

On the other hand, by operating the motor 18 shown in FIG. 3, the slider 11 is raised and lowered, and the movable base 12 and the basket 1 are raised and lowered accordingly. Also second
By running the carts 8 and 10 shown in the figure,
The basket 1 is transported horizontally.

By combining the above operations, a series of plating processes is performed, for example, as follows.

In FIG. 1, the processing tank 3 is
When the basket 1 is delivered to the vicinity of the basket 1, the holder 13 holds the basket 1 as described above and pulls it upward. Subsequently, the basket 1 is conveyed to above the processing tank 3, and then lowered and immersed in the processing liquid in the processing tank 3. When the processing in the processing tank 3 is completed, the basket 1 is pulled up, and in the pulled up state, the basket 1 is subjected to rotational and vertical vibrations as described above. As a result, the processing liquid adhering to the basket 1 and the workpiece falls, and the liquid draining is completed. Next, the basket 1 is transported horizontally and then immersed in the next processing solution. Thereafter, similar operations are repeated to complete a series of processes.

(Effects of the Invention) As described above, according to the present invention, it is possible to apply vertical and rotational vibrations to the workpiece, so that liquid can be drained sufficiently. Furthermore, since the air cylinder 21 (vertical direction drive mechanism) and air cylinder 40 (rotation direction drive mechanism) are attached to the movable base 12 attached to the slider 11, the structure can be made more compact.
