Description

[Detailed Description of the Invention] (Objective of the Invention) [Industrial Field of Application] The present invention is useful for plating small items, anodizing, painting, preparing phosphate coatings, pre-rust removal for electrical discharge machining, etc. The present invention relates to a shaking and taking out device that can be suitably used for purposes such as degreasing, deoiling, washing and processing of granular food materials.

“Jubei technology” (1) Background When surface treatment is applied to metal (including some plastics) materials or molded products such as plating, anodizing, painting, chemical modification with phosphate film, or painting. requires rust removal and degreasing as pre-treatment, which requires a series of steps: pickling → neutralization → alkaline cleaning → water washing. Automatic cleaning equipment for this purpose uses acid solution, alkaline solution, etc. The most commonly used method is to hang the item to be treated on a mobile hacker and move it up and down in an independent tank containing fresh water, etc. In this case, the item is hung up after finishing treatment in the first tank. The hacker rises, descends again at the top of the second tank, performs a vertical movement, then rises, descends above the subsequent tank, and moves up and down again, which is repeated in sequence.For small items, A basket containing the target item is used instead of the hacker, but it is basically the same as the former.

(2) Problems with the prior art However, the above-mentioned known device not only requires a mobile hacker, so it is not only large-scale in terms of equipment, but also suffers from corrosion because the liquid it handles is a strong acid or strong alkali. It is difficult to avoid. In particular, it is virtually impossible to completely make rails for travel, hydraulic or pneumatic cylinders or chains for vertical movement resistant to acids and alkalis.

[Problems to be Solved by the Invention] Therefore, the main problem to be solved by the present invention is to provide a new washing device that does not require vertical movement or running of article hanging means in known continuous washing devices. is 6
A further object of the present invention is to provide a shaking and dispensing device which can be used alone for cleaning and other purposes.

[Structure of the Invention] [Means for Solving the Problems] (1) Overview In order to achieve the above-mentioned problems and objects, the shaking and take-out device according to the present invention has a structure in which the tank is mounted on the top of a tank with an open top surface. a basket having an opening surface not larger than the opening surface of the tub and swingable along the vertical cross section of the bath, the basket pivoting outwardly as necessary to remove the contents in the bath get. 6. Below, the main elements related to the structure of the invention will be explained in sections.

{Two tanks The structure of the tank itself in the present invention is basically the same as a conventional cleaning tank, etc., and a tank with an open top is used, but corrosion-resistant materials are used depending on the properties of the chemical solution to be applied. It goes without saying that the material should be coated, lined with a corrosion-resistant material, painted, etc. Generally, stainless steel tanks, enameled tanks, etc. are used, but aluminum, wood, etc. can also be used in some cases.

A liquid supply pipe, a liquid drain pipe, etc. are attached as necessary.

(3) Basket The basket, which is an important element of the present invention, is made of a corrosion-resistant material, has an opening surface not larger than the opening surface of the Japanese cypress, can swing along the vertical cross section of the tank, and also has a It has the function of being able to rotate outward, preferably by 180 degrees, depending on the tank, and is installed so that its opening surface in its steady state is approximately parallel to the opening surface of the tank. It is preferable to provide a crosspiece in the direction perpendicular to the swinging surface in order to prevent the contents from shifting and at the same time to prevent the contents from falling prematurely.In addition, when this crosspiece is attached, the contents In order to completely drain the
Preferably, it can rotate by 80 degrees.

(Space below) A) Basket swinging and rotating mechanism The swinging and rotating mechanism of the basket is a design issue, but it is generally driven by a deceleration motor via a timing belt and toothed boot. It is easy to create a structure that In reality, the number of oscillations is sufficient within IO times/min.
It is possible to apply extremely large torque to the swing shaft considering the size of the prime mover. Therefore, a small motor is sufficient even considering the weight of the basket, the water flow resistance it receives, and the weight of the articles to be processed.

The oscillation is performed, for example, by the reciprocating movement of the motor by a first timer switch, and when this reciprocating movement reaches a predetermined number of times according to the integration circuit, the timer circuit shuts off and
The motor is directly rotated by the parallel shunt circuit, and when the basket rotates in the ejection direction and finishes discharging the contents, its upper edge (lower edge in the upside down state) collides with the limit switch and at the same time This is done by setting the motor circuit to be connected in the reverse direction by the second timer switch, thereby rotating in the reverse direction again to the original position, and then returning to the control of the first timer switch.

It is sufficient to provide one set of these control devices common to all tanks.

The above is an example of individual control, but instead of individual control, overall control using perforated tape or magnetic tape is useful for simplifying the structure of the control device.

In addition, in order to avoid shocks that may occur when changing the direction of swing and rotating, each swing (rotation) shaft should be equipped with a sliding mechanism against excessive torque, or a mechanism such as an electromagnetic clutch should be installed between it and the drive shaft of the motor. It is desirable to have a relay means.

(5) Accessory equipment Although not essential for the purpose of the invention, it is preferable to add means for supplying and receiving the treated material at the beginning and fif& (in the case of a single tank, before and after the tank), respectively, of a continuous row of tanks. .

[Function] According to the present invention, the basket in each tank swings to uniformly perform treatments such as cleaning and neutralization on the objects to be treated, and at the same time,
By rotating the basket, the items that have been processed can be automatically transferred to the next tank one after another, and then discharged and transferred out of the system in a chronological manner, eliminating the need for hackers to lift and lower the objects or for any traveling equipment. Therefore, installation costs, maintenance, lifespan, etc. of the equipment can be significantly improved.

Although the standard method of using the device of the present invention is to connect multiple tanks in series, a single tank can also be used for various purposes such as washing, dyeing, bleaching, swelling, impregnation, and extraction. Can be used for any purpose.
