Abstract

PURPOSE:To remove a surplus treatment liquid in a recessed part of a treatment substance efficiently and exactly, by constituting so that a centrifugal treatment case can be inclined by about 45 degrees from its vertical attitude, and also it can be rotated slowly. CONSTITUTION:A treatment substance in a centrifugal treatment case 29 whose contained treatment liquid is removed centrigugally by quickly rotating after immersion treatment takes a moving attitude in the case 29 since the case 29 is inclined upward by operating a tilted cylinder in the following surplus liquid removal promoting stage. Subsequently, the case 29 is set to an inclined attitude, and when it is rotated slowly, the treatment substance always tends to drop in the lower direction and also is raised in the upper direction of the inclination, therefore, the attitude and the contact are varied remarkably by its free stirring operation, and as a result, the surplus treatment liquid is removed naturally and gradually from the recessed part, etc. Then, the case is returned to its vertical attitude while rotating slowly, and is subjected to the final quick centrifugal rotation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for removing excess processing liquid adhering to immersed objects, and in particular, 2) lifts the immersed objects by immersing them in a predetermined O treatment solution and simply centrifuging them. It is an object of the present invention to provide an apparatus designed to not only remove excess processing liquid by removing the excess processing liquid, but also extremely efficiently and reliably remove excess processing liquid that cannot be removed by itself, for example, in the recess of the processing object. It is something.

For example, the surface of mechanical parts such as bimetals and bag nuts is treated with various coatings (depending on the dipping method), and the stone is
In this case, when the immersion is finished, the immersion case is used as the tf' centrifugal processing case, and the processing liquid □ remaining inside the case is centrifugally removed to provide a uniform and high-quality product with less unevenness. That's it.

However, the methods to date only use the above-mentioned centrifugal treatment as the final process. It would be better if the recesses were oriented in the outer diameter direction of the centrifugal processing case, i.e. in the direction in which centrifugal force acts, but if the recesses are oriented in the opposite direction or orientation, excess processing liquid remaining in the recesses will not be able to be centrifuged. ``As a result, more processing liquid than necessary solidified in the recesses, resulting in remaining defective parts.'' This phenomenon occurs, for example, in processing cases. The conventional device ice:
This means that it could not be completely removed.

This invention was made with attention to these facts.
Therefore, the feature here is that a processing frame serving as a fixed frame supports a case rotating head that is movable in both horizontal and vertical directions.

A centrifugal processing case that can accommodate processed materials with or without a recess is rotatably supported on a case rotating head in a vertical axis position, while a immersed cypress containing a desired processing solution is placed in a fixed position. In the device for removing excess processing liquid adhering to the immersed object, the pre-delivery core processing case is capable of reciprocating between the vertical axis attitude and a desired tilted attitude, and the case The means for applying rotation to the rotor is more advanced than that for setting even slow rotation.

The present invention will be described below with reference to illustrated embodiments.

This traveling trolley (7) can move forward and backward in the forward and backward direction.
At the same time, an elevating guide frame (8) and an elevating drive screw shaft (9) hang from the same dolly (7) in parallel and are fixed. In this case, the elevating guide frame (8) ) is a pair of left and right rectangular cylindrical lifting rails αi and a lower frame 0 that connects and integrates their lower ends, and is 1 kb, and in consideration of balance, power is distributed to the − scraper of the trolley (7). The elevating drive screw (9) is disposed at the center of the front side thereof, and is configured to be rotated reciprocally by the elevating drive portion (2) at the top.

The lifting guide frame (8) has left and right lifting rail bodies (2).
An elevating arm (toward) that is raised and lowered along the front is installed in a forward-extruding manner. This elevating arm (2) has a pair of left and right arm bodies (to) that protrude forward on both sides of an arm base frame (to) equipped with an elevating guide roller α4, and a space between the two bodies α. It is formed as a frame body with a bottom plate (B) integrally welded to the arm base frame (To), and the screw nut (To) fixed to the front and center of the arm base frame (To) is screwed into the lifting drive screw shaft (9) to provide lifting force. The lifting stroke is set within the range shown by the imaginary line of the lifting guide roller trout in FIG.

On the other hand, a pair of left and right pivot bearings Q are fixed to the front end of this lifting arm (to), and when the pivot (2) is set on these, the vertical case rotating head It is a pivot point.

This head (2) has a hydraulic motor shaft and a gearbox (2) at its upper end, and is well supported halfway down the lower part.This head is tilted approximately 45 degrees forward from the vertical position shown in the figure. It is equipped with a tilt cylinder (Incorporated) to enable tilting. 1 In the normal vertical position, the return stopper (to) k, which is hung in an L shape from the bottom bracket (2) of the lifting arm (to), The shoe pad (2) at the bottom of the head (2) is fitted in a tapered shape to provide a stable and reliable vertical position.

A vertically oriented centrifugal rotating shaft (to) is supported on this head, and its lower end protrudes below the outside of the head (2).

At the lower end of this centrifugal rotating shaft (2), a vertical shaft type centrifugal processing case holder is attached with bolts as shown in the first figure.

This processing case is of a small capacity (small diameter) type in Figure 1, but in order to make its structural special purpose easier to read, it has a large capacity (small diameter) type.
Large diameter)! l! This will be explained using the processing case (to).

Figures 2 and 5 show its structure, and roughly speaking, it has an inner case plow on the innermost periphery and an outer case plow on the outer periphery. A prevention tube (2) is assembled.

That is, the structure of the outer case (■) integrates an outer bottom plate (top), which has a bottom inner ring (top) and a bottom outer ring (bottom 7) concentrically, and an outer cylindrical body (top) above the bottom plate. Along with the outer bottom plate (to)
The truncated cone-shaped outer core body (2) is greatly bulged and integrated at the upper center of the body, while the vertical reinforcing plates (2) are arranged radially equiangularly around the outer periphery of the outer body body (2). These vertical reinforcing plates are arranged integrally and are provided with an upper attachment 7 langes at their upper ends, and horizontal reinforcing plates are fixed and integrated in the middle.

In this case, the outer bottom plate (to) and the outer cylinder body (to) have an opening degree of 30 with a large number of round or elongated second exclusion ports (2).
% punched metal.

The one-way case has an inner core body, an inner bottom plate, and a cylindrical body in the same manner as the present case, and the entire body is made of mesh as shown in FIG. 4, and has a first exclusion row.

This inner case (to) has a hole in the center with respect to the outer case (2) K.
When the ring rods are fixed in place and ring rods are interposed at various places between the inside and outside, flow-promoting gaps shown in FIGS.

In addition, as shown in the conventional example shown in Fig. 6, the wind prevention tube (2) has a vertical reinforcing plate (to) which generates considerable wind noise due to rapid centrifugal rotation. In order to improve the soundproofing effect, it is made of punched metal with a long hole (or round hole) shaped third exclusion port as shown in Figure 5. The centrifugal rotating shaft (2) side is attached to the upper mounting 7 by bolting the detachable rotating base on the centrifugal rotating shaft (2) side.

The centrifugal treatment case holder and its operating system are constructed in this manner, and the immersion treatment tank and other means for carrying in and out thereof are constructed as follows.

First, the structure of the treatment tank m (small size) K' is shown in Figures 7 to 10. In other words, the ring is filled with demersal fish, and the treatment tank main body, which has an inverted side surface, is connected to the ring through its outer periphery. It is being

The main body (■) has a cylindrical vertical body part and an oblique body part which is integrated with the upper part of the body in a manner to communicate with the sides. Removable and detachable:・″・・Ill,
II The structure is as follows: 1. Here, the ring is a stirring door that can be opened and closed at the top of one side of the vertical body part, and as shown by the broken line in the first figure, the processing liquid, which is paint, is stored up to a level corresponding to K9 slightly below the door. do. Also, - is a hanging piece.

This processing tank is equipped with the following lifting/lowering closing device to completely prevent scattering (during centrifugation, which will be described later).

The main parts of the apparatus are shown in FIG. 9 (front view) and FIG. 10 (plan view). That is, the trunk is an adjustment window recessed in a U-shape on the upper end side circumference of the vertical trunk, and adjustment rails T4- are loosely installed on the outer wall of the vertical trunk to correspond to both sides of this window. A guide groove (■) is formed. IN) is a joining plate, which integrates an arc plate-shaped inner blocking plate fixed to the inside and an outer blocking plate of the same shape, separated from each other inside and out, which constitutes an opening/closing response plate. At the same time, the inner blocking plate is attached to the inner periphery, and the outer blocking plate branch moves up and down along the guide groove 2 as shown in Fig. 9, and when it moves downward, it is released against the return spring tRk, and the same spring tRk is released. (It will return automatically).

As will be described later, this is a relationship in which the L-shaped return stopper moves up and down as the bath is immersed.

On the other hand, the diagonal body ring is formed of a U-shaped frame 610 with the opening facing upward, and its diagonal bottom wall allows the processing case handle to be tilted as will be described later, and also allows the processing liquid to be removed and dripped to be removed from the vertical body. The water is returned to the Shonai.

The immersion treatment tank is constructed in this manner and is kept on standby at a predetermined position, but since there is another waiting time in the loading/unloading means, this will be explained below.

That is, FIG. 1, FIG. 7, and FIG. 8 are explanatory diagrams thereof, and v) is the first
This is a processing tank installation stand, and as shown in Figure 8, it is installed in pairs on the left and right, and a large number of floating loaf branches are arranged on each side in the form of a horizontal axis.

On the other hand, one is a treatment tank transport trolley with caster and steering handles.
Q is provided, and the same pair of left and right second treatment tank installation stands (2) and idle rollers (2) are placed on the base plate.

In this case, the first centering stopper (c) for both processing cypress installation stands V) (to) is installed so that it protrudes from each roller ■, and this stopper (2) always protrudes. On the other hand, the second alignment stopper (c)... is.

411 A pair of first processing tanks are installed on the front side of the trolley.A pair of first treatment tanks are installed on the front side of the architrave (a pair of supporting cylinders are installed on the front side of the architrave and are lower than each roller as shown in Fig. 7). It is a turtle that is removably fitted to the 17G.

Here, there are two types (multiple types) of centrifugal processing cases, large and small. As shown in Figure 7, the 9m reeds are configured in such a way that they are installed in completely concentric positions with common @1 and 2nd alignment stoppers (to), regardless of their size. be. That is, with the large processing tank as the largest reference, the first and second centering stoppers (c) are arranged according to its diameter (4).

For small processing tanks, the diameter of the body (because the peaks are too small to fit) is attached with an auxiliary adjustment board (c), and the processing tank is set as a set piece (c) on the board (c). ...I was able to standardize the stopper (c) by fitting it in.

(to) is a forward stop frame that is erected on the intermediate frame (to) installed horizontally between the front fireflies of the base frame (2), and when viewed from the front, it has a gate shape and its upper end is on the rear side. The front surface of the lower end of the elevating guide frame (8) during forward movement comes into contact with a pair of rubber pads equipped with an INK to stop the elevating guide frame (8). In addition, η is a stand that is erected left and right on the base frame (2) and serves as a lifting guide frame (8) when stopped.
Fix with clamp cylinder ■ from left and right.

Therefore, the operation status of the immersion treatment equipment constructed in this way will be explained as follows.

First, prior to the dipping treatment process, a dipping treatment tank is selected according to the size of the centrifugal treatment case, and a hanging/hanging piece ■ is hooked on the running lane (not shown). A treatment tank is installed on a treatment tank transport trolley located outside the figure. In this case, the first and second centering stoppers (2) t◆ perform the centering function and stabilize it. In this way, the transport cart -
・8 As shown in the figure, dock the first treatment tank concentrically at the front end of the installation stage. If you remove all the second centering stoppers ◆ from this point, the space between the front and back of the first centering stopper t71 (c) becomes free, and the processing tank 11□ is moved through the free rollers. 11 Carry it in until it hits the first alignment stopper (c) k on the first treatment tank installation stand i, and then insert the second alignment stopper shaft again to complete the setting at the desired center position. can always be matched to a defined center. Exporting will be carried out in the reverse manner.

On the other hand, in this kind of immersion treatment equipment, a reversing drum (not shown) is installed perpendicularly to both sides of the rear side, and the material to be treated is inverted and introduced into this equipment from one side, and the centrifugal treatment case is held by a ball roller so as to receive it. (not shown), an appropriate amount is received by waiting thereon, and the processed materials described below are transferred to the next processing step by the other reversing drum (not shown) K.

In this way, the received processing object 1, for example, a flat screw with a recess for a screwdriver in the head plate as shown in FIG. 12, is placed in the centrifugal processing case (2) to the extent shown in FIG. ) is inserted, and by lowering the attachment/detachment rotating base by the elevating drive screw shaft (9), the case frame is connected and the standby state as shown in the first figure is obtained.

First, in the immersion treatment process, the processing case is once raised high through the raising process shown in Figure 1 (■), and the forward movement step 14 is carried out. ) K makes contact and the forward movement is stopped, and the clamp cylinder @ is used to clamp from both sides to stabilize the centrifugal operation, etc. At this point, the processing case handle has already been aligned above the processing liquid member.

Next, as shown in step θ, the lowering starts, and the voice stops (it continues to lower and return to normal), and the next lowering step is OK.

Here, the processing case handle is immersed for about 273 degrees in the processing solution (1), and the paint is immersed into the processing material contained therein.

In this case, by opening the stirring door ring in advance, the processing liquid is sufficiently stirred by a special stirrer (not shown), but the mold speed stirring may also be carried out by the processing case itself, as shown in X in the first diagram. .

In such a case, in the descending process of O, the return stopper (to) is pressed down on the opening/closing response plate -, so that the opening/closing response plate -, which responds downward, is allowed to immerse freely, while the ascending line IIK of When the temperature rises, the following first centrifugal removal step 1 ctip @3111 from the processing case
It prevents the external scattering of 1Ef+ls and has a rating of 415.

After the immersion treatment is completed in the above step (2), the liquid (3) is centrifugally removed by rapid rotation in the X and Y directions.

However, according to the processing up to this step, the processing driving wheel inside the processing case handle is as shown in Fig. 12 (with its concave part (■) facing the center of the case), or its threaded part and the mating threaded part (
Alternatively, since the liquid is centrifugally rotated while being in constant contact with the inner surface of the case, the process ends in 1 without sufficient liquid being removed by centrifugation. Therefore, the next step was to promote the removal of excess liquid.

In this process, the processing case holder is tilted upward by the tilt cylinder HiC, and the object to be processed (2) is set in the first stage to be moved as shown in FIG.

After taking the tilted position shown in FIG. 11, it is slowly rotated in the X direction (the direction is not particularly limited).

Along with this, the processed material ■ always falls in a lower direction as shown in Fig. 11 6! While trying to move, it is lifted upward on the slope, so its free stirring action makes it suitable for that position.

The contact point changes greatly from before, and as shown in Figure 12 (the concave part ■ changes to the direction in which centrifugal action works), the contact point changes. The processing liquid is naturally removed and recovered through the slanted bottom wall, and the surplus is removed to become the processed material.

Next, a step of slowly rotating the processing case handle and returning it to the vertical position is carried out.

This aims at a more sufficient removal action, and also serves to change the internal process material, which has been accumulated on one side due to tilting and rotation, to an even distribution around the circumference that is optimal for centrifugal removal. The processing wheels that have been distributed through this step (1) are returned vertically and subjected to rapid centrifugal rotation in the X-Y direction.As a result, excess liquid that is about to leak out due to tilting rotation and liquid that is still accumulated can be removed. Finally, completely remove it.

'1:.

In this way, the steps of immersion, fs1 centrifugal removal, removal promotion, and second centrifugal removal are explained, but in this case, one more important effect is that which depends on the processing case (to) K of a special structure.

Todoroki 17 In other words, the inner case (to) not only has an inner core trunk ring in the center and has the function of predistributing the processing driving wheels to the outside.
Since the inner case ■ itself is made of knitted mesh, the degree of contact with the processing material ■ is slight compared to a book whose inner case is a simple punching metal k, and this makes the removal of excess liquid extremely effective throughout the entire process. As a result, it is possible to provide a structure that is inexpensive, bulky, and easy to install.

At the same time, the wind noise prevention tube (2) on the outer periphery contributes to preventing the wind noise caused by rapid rotation as described above, ensures smooth rotation without rotational resistance, and can be reinforced as a structural member.

The present invention is as described above, and therefore, according to the present invention, an object that has been immersed in a predetermined treatment liquid is elevated, and the excess treatment liquid is removed simply by centrifugal rotation. For example, it has become possible to remove excess processing liquid in the recess of the processing object extremely efficiently and reliably, even if it cannot be removed by this method alone. In particular, this device is excellent in that it can be made into a device 618 with extremely high removal effects by simply adding a very simple configuration to the previous device.

The helmet may be rotated slowly in the step θ, in which case further removal is expected. In addition, the processing driving wheels include all those with recesses, and not only large ones that centrifugally rotate a single unit, but also four types including those without recesses, and those with recesses. The recess has a very wide meaning and includes, for example, a circumferential groove-shaped book, and the processing liquid can also cover a wide range of areas (for example, not only paint).
This term includes rust preventives, electrolytes, oils, etc.
