After a prescribed time passes, the rotation of the first motor 11 is stopped and a second motor 12 is rotated clockwise to wind up a winding up chain 27 and under this condition, liquid dropping is carried out.

Description

Detailed Description of the Invention [Industrial Field of Application] The present application relates to a method and apparatus for dipping an object such as a core metal of a rubber baked part with an adhesive, etc. Regarding things that have improved and made work more efficient.

[Conventional technology] In the conventional adhesive application process using dipping, a basket containing objects to be processed is lowered with a chain or the like from above the adhesive liquid tank, immersed in the adhesive liquid, and then swung in the liquid to prevent dipping. After that, the sauce was removed and dried by pulling it out of the liquid and standing still.

Also, the baskets get clogged by the adhesive during dipping, so after several turns of the adhesive application process, each time the baskets become clogged, remove the baskets and stack them up. They were then immersed in a solvent and cleaned manually.

[Problems to be Solved by the Invention] However, in the above method, since the basket is manually swung during dipping, the objects to be processed cannot be sufficiently stirred inside the basket, and the objects to be processed remain on top of each other. There are cases,
In such cases, the adhesive may not be applied in some areas, resulting in uneven coating. Further, even during drying, the coating film thickness may become uneven due to the objects to be treated adhering to each other, or drying with sagging and solidifying in a partially raised state. Moreover, such manual work has problems such as uneven work and is time consuming, so it has been desired to improve work efficiency.

Furthermore, the above-mentioned cleaning method is uneconomical in that it requires a large number of baskets, is inefficient in that it has to be attached and detached each time it is cleaned, and it is difficult to clean the baskets after leaving them for a relatively long time. Therefore, the adhesive adheres strongly and is difficult to clean, which may affect the quality of subsequent dipping. Moreover, manual cleaning has tended to be avoided by workers who are forced to come into contact with solvents.

Therefore, the main purpose of the dipping treatment method according to the present application is to enable uniform coating film formation and to improve work efficiency.

In addition, it is an object of the present invention to continuously and efficiently perform the washing process of the cage.

In addition, the main purpose of the dipping device according to the present application is to provide a device that enables the above-mentioned advantageous dipping method, and also to simplify the structure and make the operation simple and efficient. The purpose is to provide a device that can

[Means for Solving the Problems] In order to solve the above problems, the dipping processing method according to the present application involves spinning a basket containing objects to be processed in advance (with a part of the basket immersed in a processing liquid) using power. After that, the basket is taken out of the processing solution and the rotation is stopped to remove the excess processing solution. It is characterized by performing rotary drying to dry the processing liquid applied to the surface of the object to be processed.

In this case, the rotating surface of the cage can be tilted during rotational dipping. Furthermore, the basket can be tilted when cutting sauce, and the tilted basket can also be continuously swung. Further, the rotating surface of the basket can be held substantially vertically during rotary drying, and at the same time, air can be blown toward the basket, and the surface of the processing liquid can be covered while the air is being blown.

After rotary drying, the basket can also be cleaned by immersing the emptied basket in a solvent and rotating it while still attached to the rotating shaft. At this time, the basket cleaning step can be performed continuously and regularly with the regular step by interposing the basket cleaning step between repeating the regular steps of rotational dipping, sauce cutting, and rotary drying multiple times. Further, the dipping treatment liquid can be an adhesive. However, dipping in the present application also includes chemical conversion treatment and the like.

The dipping processing apparatus according to the present application includes a basket capable of accommodating objects to be processed, a rotary shaft with which the basket is removably cantilevered at its distal end, and a support member that swingably supports the proximal end of the rotary shaft. , a rotary drive means for rotating the rotary shaft;
The apparatus is equipped with an oscillating drive means for causing the tip side of the rotating shaft to oscillate from approximately horizontal to approximately vertically downward, so that a small portion (at least a portion of the cage) can freely move in and out of the liquid tank. At this time, the inner wall surface of the liquid tank may be made into an inclined surface.Also, the frame member of the basket may be made into a round bar shape.Furthermore, the duct that blows air to the basket during rotary drying may be connected to the support member. It is also possible to provide one.

A horizontal drive means is provided to horizontally move the support member itself together with the cage, and the cage can be selectively moved horizontally to a position above or not above a liquid tank previously arranged along the movement line of the cage. can. In this case, the supporting member can be moved in the horizontal direction, the rotating shaft can be rotated, and the neck can be vibrated while the car is still attached.

Further, if the liquid tank is composed of a processing liquid and a cleaning liquid, dipping and washing of the cage can be performed continuously by selectively moving the support member above one of the liquid tanks. Furthermore, a brush can also be provided in the cleaning tank.

The movement of the support member, the rotation of the rotating shaft, and the vibration operation of the neck in these dipping steps and the basket cleaning step can be continuously and automatically controlled by an automatic control means.

[Operations and Effects of the Invention] In claim 1, when the basket is powered and rotated through a rotating shaft during dipping and drying, the contents of the processed material are sufficiently stirred inside the cage, so that the processed material is are difficult to overlap each other. Therefore, in rotary dipping, the treatment liquid is uniformly applied to the surface of each object to be treated, and in rotary drying, the coating is quickly dried while maintaining a uniform coating. Also,
By removing the sauce prior to rotational drying, it is possible to prevent the processing liquid from scattering during rotation and to speed up the drying. Moreover, since it is a powered rotation, there is less unevenness in work (
And since it can be done in a short time, it can improve work efficiency.

In claim 2, when the rotating surface of the basket is tilted during rotational dipping, the objects to be treated are stirred in a three-dimensional and complex manner inside the basket, so that mutual overlap between the objects to be treated is further reduced. In addition, the treatment liquid can be applied more evenly and uniformly.

In the third aspect, when the basket is taken out of the processing solution and stopped rotating after rotational dipping, the excess processing solution remaining in the basket drips quickly, so that the sauce can be removed quickly.

In claim 4, when the basket is continuously swung and its inclination angle is changed during the sauce removal, the sauce removal can be further facilitated.

In claim 5, when the rotating surface of the cage is made substantially vertical, the objects to be processed inside the cage are stirred in an orderly manner so as to behave two-dimensionally along the rotating surface in the substantially vertical direction, so that the objects to be processed are mutually agitated. There is less overlap (and the thickness of the coating film is less likely to be uneven during the drying process), making it easier to form a uniform coating film (and drying quickly).

In claim 6, when air is blown toward the rotating basket, -layer drying becomes faster.

In claim 7, if the surface of the processing liquid is covered with a lid or the like during air blowing, scattering of the processing liquid can be prevented.

According to an eighth aspect of the present invention, after the contents of the basket are emptied after rotational drying, the contents of the basket are emptied and placed in a solvent solution and the basket is rotated again, whereby the basket is rotated and cleaned to remove clogging. Therefore, the cleaning work can be made easier, and since it can be washed immediately after the dipping process, the deposits can be removed better in a short time (thus, the cleaning time can be shortened. Moreover, the amount of deposits that are not removed by cleaning can be reduced). Since the amount of these deposits mixed into the processing solution is small, the quality of the day rubbing process can be stabilized.

In claim 9, if the cleaning process is inserted between repeating the regular process a plurality of times, the regular process of dipping and washing the basket can be performed regularly as a series of continuous operations, and the cleaning process can be specially performed. Since the cleaning can be done more frequently without having to do it in a separate location, clogging of the basket can be prevented at all times. Therefore, work efficiency can be further improved,
At the same time, it is possible to improve the quality of dipping.

In claim 10, in the case of adhesive dipping treatment, the basket is likely to become clogged due to the viscosity of the adhesive;
By performing such dipping followed by washing, clogging can be prevented.

In an eleventh aspect of the present invention, the rotating shaft supported in a cantilever manner on the distal end side can be rotated and vibrated by the rotational driving means and the oscillating driving means. Therefore, only the tip end of the rotary shaft can be moved up and down between the horizontal and downward states using the swinging drive means, and the tip end of the rotary shaft can be tilted downward to move the car a little (and partially into the liquid tank). When the contents are placed in the basket and rotated by the rotary drive means, rotational dipping is performed if the contents are processing liquid, and washing of the basket is performed if the contents are a solvent.At this time, the tilt of the rotation axis can be adjusted arbitrarily by the swing drive means. In addition, the cage can be rotated with its rotating surface tilted, making it suitable for rotational dipping.

After rotational dipping, the rotary shaft is moved upward by the oscillating drive means to tilt the basket with it above the processing liquid, and the rotary shaft is held in a stopped state to perform dripping. It is also easily possible to swing the rotating shaft so that the inclination of the rotating shaft changes continuously during this sapping process. After cutting off the sag, the rotary shaft is made substantially horizontal by the swing drive means and rotated by the rotary drive means to perform rotary drying. Therefore, the rotation, vertical movement, and tilting of the car can be easily performed on one axis, and the structure of the device is simplified.

In claim 12, when the basket is tilted during dipping, if the wall surface of the liquid tank is made sloped to correspond to this, the internal capacity can be reduced accordingly, which is economical, and the replacement cycle of processing liquid etc. can be made faster ( quality can be maintained at a constant level.

In claim 13, by forming the frame member of the basket in the shape of a round bar, dripping of excess processing liquid can be facilitated, so that dripping can be done more quickly.

In claim 14, the ventilation duct is integrated with the support member, so that even if the support member moves, the positional relationship between the basket and the duct can be maintained constant at all times.

In claim 15, when the support member is horizontally moved by the horizontal movement drive means, the car is also horizontally moved together,
In addition to being able to move up and down due to the vibration motion of the rotating shaft, the cage can also be moved in the perpendicular horizontal direction.The cage can be selectively moved onto a liquid tank that has been placed in advance along the movement line of the cage to perform rotational dipping. It is possible to carry out processing such as cutting and rotary drying.

By selectively moving it to a position other than above the liquid tank, the material to be processed can be loaded or taken out.

Moreover, if a plurality of liquid tanks are provided along the moving line of the cage, dipping can be performed continuously several times by sequentially moving the support member for each liquid tank. Therefore, by rotating and changing the inclination of the basket while it is attached to the same rotating shaft, each processing operation such as rotary dipping, sauce cutting, and rotary drying can be performed, and there is no need to attach or detach the basket. , work efficiency is good.

In claim 16, after the dipping step, after the contents are emptied with the basket still attached to the rotating shaft, the support member is selectively moved onto the washing tank by the horizontal drive means, and the basket is moved by the swing drive means. If the basket is placed in a solvent solution and the basket is rotated again, the basket can be rotated and cleaned while remaining attached to the same rotating shaft. Therefore, there is no need to attach or detach the basket during cleaning. Moreover, it can be washed immediately after the dipping step. Further, since cleaning is performed by power rotation of the rotating shaft, there is no need for the operator to come into contact with the solvent.

In claim 17, when the basket is rotated in the cleaning tank,
Since the brush comes into contact with the surrounding area of the basket, cleaning efficiency is higher.

In claim 18, if the movement of the support member, the vibration motion of the rotary shaft, and its rotation are automatically controlled by the automatic control means, each process can be automated and work efficiency can be improved.

[Example] Hereinafter, embodiments will be described based on FIGS. 1 to 9.

Figure 1 of Dipping is a conceptual diagram showing the entire adhesive dipping and basket cleaning process. Consists of (P.4). Of these, (P・1), (P・2), (P・3)

In addition, in the figure, the front view of the car 1 is shown in the upper row, and the side view of the car 1 is shown in the lower row for each sub-step. First, the basket 1 is moved onto the processing liquid tank 4, and the rotating shaft 5 is positioned approximately horizontally (P.2.1). Next, by swinging the rotating shaft 5, the cage mounting side is tilted downward, the cage 1 is flattened into the processing liquid tank 4, and rotational dipping is performed by rotating it together with the rotating shaft 5 (P.2. 2). After a predetermined period of time, the rotation of the rotating shaft 5 is stopped, and the car 1 is returned to a substantially horizontal position.
is removed from the processing liquid tank 4, and the excess processing liquid is drained off while the rotating shaft 5 is stationary (P.2.3). Thereafter, the rotary shaft 5 is rotated and hot or cold air is blown from the duct 6 to dry the product by rotation (P.2.4).

At this time, the processing liquid tank 4 is covered with a lid 7.

Depping FIG. 2 is a diagram schematically showing the entire processing apparatus. Two guide rails 9.9 are provided on the wall inside the booth 8 and extend vertically parallel to each other in the depth direction, and the slider 10 is supported on these. has been done. The slider 10 is a specific example of a support member in the present application, and supports the basket 1 in a detachable manner and can be guided and moved by the guide rails 9.9. Also,
A first motor 11 for rotating the car 1 and a second motor 12 for causing the rotating shaft 5 to vibrate in order to tilt the car 1 are provided. The car 1 is engaged with a screw shaft 13 provided between guide rails 9 and 9 in parallel with the guide rails 9 and 9, and is moved according to the amount of rotation of a step motor 14 provided at one end of the screw shaft 13. ing. Further, although shown by imaginary lines in the figure, the duct 6 is mounted on the slider 10 so as to be located around the car 1. 1st motor 1
1, the second motor 12 and the step motor 14 respectively constitute a rotational drive means, an oscillation drive means, and a horizontal direction drive means in the present application, and the controller 1 consisting of a sequencer
5.

The controller 15 includes a step motor 14 and a first motor 1.
It is electrically connected to each of the first and second motors 12 and the ventilation duct 6, and sequentially controls the operation of each at every predetermined processing time. It goes without saying that the set time for each operation can be set arbitrarily by the operator. However, the controller 15 can be a microcomputer, in which case more detailed control can be performed.

Below the guide rail 9.9, along the moving direction of the basket 1, there are one or more liquid tanks, namely the processing liquid tank 4 and the cleaning tank 1.
6 is placed. The number of processing liquid tanks 4 is increased or decreased as appropriate so that the number corresponds to the processing contents. The processing liquid tank 4 of this embodiment is
It is configured for two-liquid processing, consisting of two tanks: a first adhesive tank (A) and a second adhesive tank (B). Hereinafter, (A) or (B) will be added to the reference numeral 4 only when it is necessary to distinguish between processing liquid tanks. Each tank 4.16 is movable on casters, and a lid 7.17 is provided on each tank so that it can be opened and closed automatically or manually. In this embodiment, the slider 10 is configured to selectively move sequentially to the processing liquid tanks 4(A), 4(B), and the cleaning tank 16, but conversely, the slider 10 is stopped and these processing steps are performed. Liquid tank 4 (A), 4 (B
) and the cleaning tank 16 side can also be moved below the slider 10 manually or automatically. An exhaust duct 18 is provided at the bottom of the innermost part of the booth 8, and preferably the outlet of the duct 6 is directed toward the exhaust duct 18.

3 shows the detailed structure of the slider 10 on the front side, and FIG. 4 shows the detailed structure on the side side. A rectangular cylindrical sprocket case 20 is connected to the slider 1o so as to be rotatable in a direction around the axis via a horizontal shaft 21 parallel to the guide rail 9.9. A driven sprocket 22 is housed in the sprocket case 20 and is rotatably attached to the end of the rotating shaft 5 .

The driven sprocket 22 is connected to a driving sprocket 24 of the first motor 11 via a chain 23. 1st
The motor 11 is connected to the sprocket case 2 by the stay 25.
Fixed above 0. Furthermore, as is clear from FIG. 4, the drive sprocket 26 of the second motor 12, which is attached to the slider 10 in a direction perpendicular to the first motor 11, is engaged with the hoisting chain 27, and one end of the hoisting chain 27 is engaged with the hoisting chain 27. is attached to a stay 28 projecting from the sprocket case 20.

When the hoisting chain 27 is hoisted up by the normal rotation of the second motor 12 (the hoisting side is called normal rotation, hereinafter the same), the driven sprocket 22 becomes in the horizontal state shown in the figure, and when the second motor 12 reverses, the hoisting chain 27 is hoisted up. When 27 is extended, the leading end of the driven sprocket 22 tilts downward to approximately 45° about the horizontal axis 21, thereby performing a swinging motion. However, the tilting angle θ (FIG. 6) during swinging can be arbitrarily set within the range of 0° to 90° with respect to the horizontal.

In this way, according to the present embodiment, since the rotary shaft 5 is vibrated in the vertical direction, there is no need to vertically move the slider 10 or the entire rotary shaft 5 (the device can be made compact and simple in structure). However, unlike the neck vibration motion, it is also possible to have a structure in which the rotary shaft 5 is extended and contracted in the vertical direction, or a joint is provided in the middle of the rotary shaft 5 and the distal end is moved up and down by the joint motion. .

The rotating shaft 5 is rotatably supported by a holder 29 protruding from the sprocket case 20 via a bearing member 29a'r.
A flange 30 is provided at its tip. A mounting seat 31 of the basket 1 is detachably attached to this flange 30 with bolts 31a.

On the side of the slider 10 facing the guide rail 9.9,
Rail engaging blocks 32 are provided above and below corresponding to each guide rail 9.9, and a slide nut 33 that engages with the screw shaft 13 is installed between the upper and lower blocks 32.32. The screw shaft 13 passes through the slide nut 33 and extends in the vertical direction of the paper. Therefore, screw shaft 1
Since the slide nut 33 receives a force in the forward and backward direction due to the normal rotation (rotation to advance the slider 10) or reverse rotation of the slider 3, the slider 10 is guided by the guide rail 9.9 and moves forward and backward. In addition, in this application, booth 8 shown in FIG.
The movement in the depth direction is considered to be progress, and the movement in the opposite direction is considered to be backward.

According to the apparatus of this embodiment, the basket 1 can be moved up and down by the neck vibration motion of the rotary shaft 5, so that all processing operations such as rotary dipping, sauce cutting, and rotary drying can be performed by moving the basket 1 to the rotary shaft 5. This can be done with the unit still attached. In addition, rotation and vertical movement can be handled by a single axis, simplifying the structure of the device. Further, by swinging the rotary shaft 5, the tilting of the basket 1 is facilitated during rotational dipping and sauce cutting, and the tilt angle can be freely changed.

In addition, since the slider 10 is movable in the horizontal direction,
The step motor 14 selectively moves the basket 1 between loading, dipping, and unloading steps, as well as between the plurality of processing liquid tanks 4 during dipping, and furthermore, moves it onto the cleaning tank 16. can be done. Therefore, continuous work can be performed with the car 1 attached to the rotating shaft 5, resulting in good work efficiency. Moreover, slider 10
Since the horizontal movement of the rotating shaft 5 and the vibration of the head of the rotary shaft 5 are continuously controlled by the controller 15, the quality of the dipping process can be stabilized, and the work efficiency can be further improved through automation. Moreover, by using the controller 15 as a sequencer, the restraining part can be manufactured at low cost. However, if a microcomputer is used, changes in the strength of rotation, continuous changes in the angle of inclination, etc. can be realized more precisely.

In addition, the duct 6 is attached to the slider 10 (and
Even if the slider 10 moves, the duct 6 can always be moved together, so the positional relationship between the car 1 and the duct 6 can be kept constant.
Convenient for blowing air.

FIG. 5 shows the detailed structure of the car 1. The car 1 has a generally cylindrical shape as a whole, and is composed of a round bar-shaped frame member 34 and a stainless wire mesh 35. A mouth portion 36 is provided on a part of the circumferential side surface.
is formed with an opening and can be opened and closed by the lid 2. Lid 2
is rotatably connected to a frame member around the opening 36 on the base end side by a hinge 37, and a hook 38 is provided on the other end side. This hook 38 can be engaged with and detached from a buckle 39 provided at a corresponding portion around the opening 36. Further, the above-mentioned mounting seat 31 (FIG. 4) is provided at the center of the negative side.

Figure 6 shows the cross-sectional structure of the processing liquid tank 4 (cross-section taken along line C-C in Figure 2).
It is shown. As is clear from this, processing liquid tank 4
At the upper inside of the frame 40 is a processing liquid storage section 4 having a substantially V-shaped cross section.
1 is provided. Of the two inclined wall surfaces forming the processing liquid storage section 41, the angle θ2 between the inner inclined wall surface 42 and the horizontal is approximately 45°, which is approximately equal to the inclination angle θ1 of the rotation center axis of the car 1 during dipping. On the other hand, the outer inclined wall surface 43 on the opposite side has a gentler inclination than this, and its angle θ with the horizontal is slightly smaller than θ2. By making the slope of the outer inclined wall surface 43 gentle, escape can be ensured when the car 1 vibrates. In addition, the reference numeral 44 in the figure is a liquid draining valve, and 45 is a processing liquid. Processing liquid storage section 4
When the inner wall of the basket 1 is made into an inclined surface, when the basket 1 performs rotational dipping while swinging diagonally downward, it can substantially follow the outer shape of the basket 1, and the capacity of the processing liquid 45 can be made as necessary and sufficient. Furthermore, it is economical because the content of the processing liquid 45 can be reduced, and the replacement cycle can be shortened to maintain constant performance.

A similar cross-section of the cleaning tank 16 is shown in FIG. The cleaning tank 16 has almost the same structure as the processing liquid tank 4,
The solvent storage portion 46 is formed into a V-shaped cross section by an inner inclined surface 47 and an outer inclined surface 48, and has respective inclination angles θ2 and θ.
, is the same as the processing liquid tank 4, and a solvent 49 which is a cleaning liquid is stored inside. A brush 50 is also provided on each inclined surface 47, 48 so that when the cage 1 is immersed in the solvent 49, the brush 50 can be contacted around the cage 1. The advantage of having the solvent storage section 46 having a substantially square cross section is the same as that of the processing liquid tank 4.

Next, each sub-step of the dipping process (P.2.1)~
(P.2.4) will be explained in detail.

(P.2.1) In the loading process for the car moving car 1 (P.1, Fig. 1), the slider 10 is located at the left end of the guide rail 9.9 (second
figure). When the charging is completed, the slider 10 moves above the processing liquid tank 4(A) on the guide rail 9.9 by rotation of the screw shaft 13 according to a command from the controller 15 and stops. At this time, the rotating shaft 5 is held substantially horizontally. Moreover, the lid 7 (FIG. 2) can be opened manually or automatically.

(P.2.2) Rotational dipping FIG. 6 shows the dipping state. Following the previous process, the second motor 12 is reversed by the controller 15 and the hoisting chain 27 is extended, so that the sprocket case 20 swings downward with its tip side centered on the horizontal shaft 21, and the rotating shaft 5 is horizontal. Since the cage 1 is tilted by θ (445°) with respect to the rotating shaft 5, approximately half of the cage 1 attached to the tip side of the rotating shaft 5 is submerged into the processing liquid (adhesive) in the processing liquid tank 4.

At this time, the rotational axis of car L is also equal to the inclination angle θ,
Approximately 45 @ What's going on.

Next, the controller 15 controls the sprocket case 2.
When the first motor 11, which rotates together with the car 1, is driven, the drive sprocket 24 rotates and transmits rotational force to the driven sprocket 22 via the chain 23, so the rotating shaft 5 rotates, and at the same time the car 1 rotates. rotates while partially immersed in liquid.

Since this rotation is performed around the tilted axis of rotation with an inclination angle θ1, the rotating surface of the cage 1 is tilted, and the workpieces 3 inside are kept well separated from each other due to complex three-dimensional behavior. Since the material to be processed 3 is sufficiently stirred in the basket 1,
The processing liquid is applied uniformly to the entire surface without the particles coming into close contact with each other.

At this time, by making the processing liquid storage part 41 have a substantially ■-shaped cross section, the amount of the processing liquid 45 that is the content can be reduced, and the replacement cycle of the processing liquid 45 becomes faster, so the quality of the processing liquid 45 can be improved. It can be stabilized and replaced easily, making it economical.

(P.2.3) After the predetermined time has elapsed, the rotation of the first motor 11 is stopped by the controller 15, and the second motor 12 is rotated in the forward direction to wind up the hoisting chain 27.
The seventh sprocket case 20 of the rotating shaft 5 is integrated with the sprocket case 20 of the rotating shaft 5.
As shown in the figure, it rotates upward about the horizontal axis 21, and in this state, the sauce is cut. At this time, the basket 1 is placed in the processing liquid tank 4 (
A), and its axis rises above the liquid level, and its axis is at an angle of inclination θ.
It is tilted by 4 (θ4 × θ1).

By stopping the rotation of the car 1 and the rotating shaft 5 in the second state and holding the rotation for a predetermined period of time, the excess processing liquid in the car 1 is quickly collected into the processing liquid tank 4. Therefore, since the sagging is sufficiently removed, the processing liquid will not be scattered around during subsequent rotary drying, and an uneven coating film will not be formed on the surface of the object 3 with partial sagging. (This makes it possible to stabilize the quality of the dipping process.Moreover, the inclination angle θ4 is controlled by the second motor 12 on the rotating shaft 5.
The degree of freedom is great because it can be set arbitrarily by simply adjusting the swing angle. Moreover, since the frame member 34 of the car 1 is made into a round bar shape, the amount of adhesion to the frame member 34 is reduced, and the dripping process is further accelerated.

Furthermore, by slowly rotating the second motor 12 in the forward and reverse directions, the rotary shaft 5 can be continuously oscillated during the sagging process or part of the time to change the tilt of the car 1.
Since it swings above the liquid level of the processing liquid 45, it is possible to further promote the removal of sauce.

(P.2.4) Rotational drying When a predetermined period of time has elapsed in this state, the controller 15 causes the second motor to rotate in the normal direction, making the rotating shaft 5 horizontal, and the first motor 11 is driven again, causing the rotating shaft 5 to rotate in the normal direction. The car 1 is rotated through the car, and at the same time hot or cold air is blown from a duct 6 provided along the side of the car, thereby performing rotary drying as shown in FIG. At this time, the top of the processing liquid tank 4 is closed with a lid 7 to prevent the processing liquid from scattering under the blowing air. Due to this rotation, the rotation surface of the car 1 becomes approximately vertical, so the workpiece 3 inside is stirred in an orderly manner so that it behaves two-dimensionally almost along the rotation surface of the car 1, and the workpiece 3 is This reduces the chance of the surfaces sticking to each other or tilting (as a result of partially solidifying and sagging), and the coating film of the processing liquid applied to the surface dries with a uniform thickness.Moreover, Since air is blown from the duct 6 in addition to rotation, drying becomes faster.Also, by directing the blowing direction of the duct 6 toward the exhaust duct 18, the amount of processing liquid splashed outside the booth 8 can be reduced. .

After driving for a predetermined time, the controller 15 sets the first mork 1.
1 is stopped to complete the drying process. Thereafter, the controller 15 rotates the step motor 14 in the forward direction to move the slider 10 onto the next processing liquid tank 4 (B), and repeats the same dipping process again with a different processing liquid. Thereafter, by reversing the screw shaft 13 and retracting the slider IQ, the removal process begins.

In this embodiment, the dipping process and the cleaning of the cage can be performed while the cage 1 remains attached to the same rotating shaft 5, so there is no need to attach and detach the cage 1 from the rotating shaft 5 each time. In addition, since the basket 1 is powered and rotated, there is little unevenness in the work (and work can be done in a short time. Therefore, work efficiency is high and the quality of the dipping process is improved. Moreover, by using rotary dipping and rotary drying, Since overlapping of the objects 3 can be avoided, the coating film can be made uniform.

Eki 2 n summer beans 1 Next, the cleaning process will be explained in detail.

In FIG. 1, when a predetermined turn of the regular process consisting of (P.1) to (P.3) is completed, the lid 2 of the car 1 is closed in an empty state, and the process moves to the cleaning step (P.4). first,
In FIG. 2, the controller 15 causes the hoisting chain 27 to be hoisted by the second motor 12, causing the rotating shaft 5 to swing upward, thereby making the rotating axis of the car 1 substantially horizontal. Next, the screw shaft 13 is driven by the step motor 14.
rotates in the normal direction, the slider 10 moves toward the guide rail 9.
．． 9 onto the cleaning tank 16. At this time, the lid 17 is opened manually or automatically.

Furthermore, when the first moke 11 is reversed by the controller 15, as shown in FIG.
7 is extended, the sprocket case 20 is tilted downward about the horizontal axis 21, and the rotating shaft 5 also swings at an angle of inclination θ with respect to the horizontal. Approximately half of the car 1 is submerged in the solvent 49 in the cleaning tank 16. This state is substantially the same as that during dipping shown in FIG. Next, controller 1
When the first motor 11 is driven by the rotary shaft 5, the car 1 rotates with a portion thereof immersed in the liquid. Due to the intense contact with the solvent 49 due to this rotation and the contact of the brush 50 with the surroundings of the rotating car 1, the car 1
Adhesives that have adhered to the surface can be efficiently cleaned. Moreover,
Washing is carried out continuously immediately after dipping, so
The processing liquid that adheres to the surface is not hardened as much and is quickly and more completely removed.

After a predetermined period of time has elapsed, the controller 15 stops the rotation of the first motor 11, and the second motor 12 is rotated forward to wind up the hoisting chain 27.
The sprocket case 20 moves upward around the horizontal shaft 21, and the car 1 escapes from the solvent 49 in the cleaning tank 16. Therefore, the rotating shaft 5 is stopped with the rotating axis slightly tilted or horizontal, and the solvent is removed. After a predetermined period of time, the first motor 11 is driven and rotated again by the controller 15, thereby rotating the car 1 via the rotating shaft 5, and at the same time blowing hot or cold air from the duct 6 provided along the side of the car 1. is sprayed. At this time, the top of the cleaning tank 16 is closed with a lid 17 to prevent the solvent 49 from scattering. After this cleaning, controller 1 is
The slider 10 is retreated out of the booth 8 via the screw shaft 13 rotated by the step motor 14 which is driven in reverse by the command No. 5. As a result, the basket 1 is transferred to a new loading process (
Moving to P-1), the regular process of dipping treatment is started again.

According to this cleaning process, cleaning can be carried out regularly in succession with the dipping treatment process, and there is no need to attach or detach the cage 1, so that work efficiency is significantly improved. In particular, since adhesives are easily clogged, cleaning must be done more frequently, so work efficiency can be significantly improved. Furthermore, since the cleaning is automatically performed using the same equipment as the adhesive application, the work can be done without the operator coming into contact with the solvent solution. Moreover, it is economical because there is no need to prepare a large number of baskets. Furthermore, since it is possible to remove the deposits more completely, there is less risk that the deposits peeled off during dipping will mix into the processing liquid 45 or adhere to the surface of the object to be processed 3, improving the quality during dipping. It can be stabilized.

Note that although the above embodiments relate to adhesive dipping treatment, the present application is not limited thereto;
It can be applied to various dipping treatments such as chemical conversion treatment.
