EXAMPLES The present invention will be described in detail below with reference to examples. 1 to 4 are views showing an example of a slide lid of the coating apparatus of the present invention, and FIG. 1 is shown in the plan view of FIG.
It is a figure which shows the state in which the slide lid of the collection tank which collected the individual tanks was opened. That is, this drawing is a cross-sectional view of the collecting tank shown in FIG. 7 taken along the line AA of FIG. 7. FIG. 2 is a diagram showing a closed state corresponding to the open state shown in FIG. 3 and 4 are detailed cross-sectional views showing the relationship between the individual lid and the seal portion of the individual tank. FIG. 3 shows an open state and FIG. 4 shows a closed state.

A collective tank 11 composed of twelve individual tanks 1 is provided with a fixed lid 2 which is integrated with an outer wall 13 of the collective tank, and the fixed lid 2 is provided above the individual tank 1. An opening having the same shape as the opening is provided in parallel with the opening at a location corresponding to the opening of the individual tank. Then, the opening of the fixed lid 2 is sealed by an individual lid 4 attached to the main body 3 of the slide lid which is movable by the slide rail 9. Further, the body 3 of the slide lid is lifted by the air cylinder 10 which moves up and down, whereby the individual lid 4 is opened. In this case, the slide lid is raised and lowered (opened and closed) by switching the compressed air to the air cylinder 10 mounted on the side wall 13 of the collecting tank with a valve. The slide cylinder 12 has a role of moving the slide lid from above the tank group when there is no tank.

The individual lid 4 is suspended from the slide lid main body 3 by a suspension bolt 8. A spring 7 is inserted between the individual lid and the slide lid main body so that the individual lid does not tilt, and the individual lid is always kept parallel to the slide lid main body. Further, the spring 7 transmits the weight of the slide lid main body to the individual lid when the individual lid 4 closes the tank. Therefore, even if the individual lid is light, the individual tank can be pressurized and sealed. Since the contact surfaces of the fixed lid 2 and the individual lid 4 are not completely flat, it cannot be said that the openings on the fixed lid are all on the same plane, but the heights of the openings are slightly different. Also, since the individual lid is hung on the slide lid body,
The peripheral edge of the individual lid and the peripheral edge of the opening are always in close contact with each other to form a closed state. In other words, the head of the suspension bolt 8 can be projected above the slide lid body 3 (FIG. 4).

The seal portion of the individual lid 4 is preferably formed so as to have the lower protrusion 14 at the peripheral edge portion so as to well include the rubber packing 6, and correspondingly, the opening portion of the fixed lid 2 described above. It is preferable to provide an upward protruding fixing ring 5 at the peripheral edge. If the rubber packing 6 is installed along the outer periphery of the fixing ring 5, the opening can be sufficiently sealed by the weight of the individual lid 4. This situation is shown in FIG. In addition, the fixing ring contains a rubber packing, and when the content of the individual tank contains an organic solvent, the vapor of the solvent contains a rubber packing component formed by contact with the rubber packing. It also has the role of preventing liquid from entering the tank.

As described in detail above, the slide lid of the coating apparatus according to the present invention includes an individual tank between the fixed lid and the individual tank group.
Formed by the space X (see Fig. 1 and Fig. 2) that straddles the group
The individual tank groups that share the vapor phase part
Although it is automatically sealed, it is also preferably used for individual tank groups that do not share the vapor phase portion (Fig. 6). In this case, the lid opening / closing method and lid sealing status are the same as above. . It should be noted that a plurality of reference characters X attached to FIGS.
In each of the figures, it is confirmed that they are continuous spaces.
It is shown. As described above, FIG. 1 and FIG. 6 correspond to each other, and show a state in which the slide lid is opened when the vapor phase portion is shared and when it is not shared. 2 and 5 show a state where the slide lid is closed when the vapor phase portion is shared,
The former shows that of the present invention and the latter shows that of the conventional product. 8 and 9 are side views corresponding to FIG. 7.

The moving mechanism for moving the main body 3 of the slide lid from the upper part of the collecting tank 11 to the other is exactly the same as the moving mechanism in the conventional slide lid as described above, and the movement explained in FIG. It is a mechanism. This mechanism will be outlined below. The individual tank group with the lid closed shown in FIG. 2 pressurizes compressed air in the ascending direction of the air cylinder 10 to raise the body 3 of the slide lid, and in this state, the slide cylinder 12 is operated to move the slide rail 9 to the slide rail 9. Then, the upper space in which the individual tank group is present is released (the state of FIG. 7). Perform the work in the tank in this state, after the work in the tank is completed, operate the slide cylinder again, return the slide lid to the original position (the upper space of the individual tank group) along the slide rail, and then lower the air cylinder. The compressed air is switched by the valve in the direction to bring the individual tank into a closed state (state of FIG. 2).

The slide lid of the coating apparatus of the present invention is shown in FIG.
As can be seen from FIG. 4, since the individual lids are hung with the hanging bolts, all individual tanks can be well sealed even in a collective tank in which the distances between the individual lids and the individual tanks are not uniform. Although this method is preferable as a method of using the slide lid of the coating apparatus of the present invention, the method of using the slide lid of the coating apparatus of the present invention is not limited to this method, and individual lids can be used. It may be fixed to the slide lid. For example, when screwing an individual lid to a slide lid with a bolt having a long threaded portion, the length between the individual lid and the slide lid is adjusted so that the length between the individual lid and the corresponding seal portion of the individual tank is the same. By adjusting the length, it is possible to seal the individual tanks corresponding to all the individual lids under the slide lids. In this case, if the slide lid or fixed lid is deformed by multiple uses and the distance between the individual lid and the seal part of the individual tank changes, adjust the above-mentioned mounting bolt to adjust the length between the individual lid and the individual tank. It should be the same again. Further, even if the individual lid and the slide lid main body are completely fixed, the slide lid of the coating apparatus of the present invention can be used, and the slide lid of the coating apparatus of the present invention can be used. Since the warping of the lid portion that is seen in the conventional slide lid does not occur, the slide lid of the present invention is superior to the conventional product also in this case.

In the slide lid of the coating apparatus of the present invention, the individual lid is sucked under reduced pressure to be sucked and held by the slide lid main body, and the individual lid is set on the individual tank and then returned to normal pressure to seal the individual tank. It can also be used in such a manner that it is tightly attached to, and air pressure is applied to tightly seal. When using such a method, it is necessary to use a device for vacuum-adsorbing the individual lid or applying air pressure to the individual lid, and it is desirable that the individual lid is made of a light and strong material such as fiber reinforced resin. . On the other hand, in the method of increasing the pressure adhesion by the lid weight, the weight of the individual lid is added to the weight of the individual lid in addition to the weight of the slide lid body to close the individual tank. It is not necessary to increase the size, but it is desirable to manufacture it with a tough material, and metal or fiber-reinforced resin may be used as the material.

The slide lid main body of the coating apparatus of the present invention and the individual lids forming the slide lid main body are not limited in shape as long as the corresponding individual tanks can be hermetically sealed without any problem, and the individual tanks having a circular opening have a rectangular shape. You may use a separate lid. Further, the shape of the slide lid body can be any shape depending on the arrangement of the individual lids. If one slide lid is used to seal a large number of individual tanks as described above, accurate placement of the individual lids in the locations where the individual tanks exist, strength of the slide lid body and moving mechanism, slide lid storage location, etc. It is desirable to limit the number of individual tanks that can be supported by one slide lid, because it is often negative in various points. Since this number varies depending on the size of the individual tank, etc., it may be appropriately determined in consideration of the size of the individual tank and its arrangement condition, etc., but generally 4 to 64, preferably 8
~ 16 pieces. It should be noted that it is not necessary to open and close 64 or more individual tanks with one slide lid even from the actual surface of the photoreceptor coating process of the photoreceptor drum where it is preferable to use the slide lid, and other aspects such as dipped coating.

[0018]

Since the slide lid of the coating apparatus according to the first aspect of the present invention seals the individual tank with the individual lid, the slide lid main body can be sealed sufficiently without warping, and the slide lid can be sealed. Since the lid is moved from the top of the tank to another, it does not hinder the work inside the tank that uses the space above the tank. Further, since the slide lid is opened and closed slowly up and down, it is possible to prevent troubles due to changes in the liquid composition in the tank and leakage of gas contained in the tank due to opening and closing. The slide lid of the coating device according to claim 2 is
Since the length between the individual lid and the slide lid body can be freely adjusted, the adhesion between the individual lid and the corresponding individual tank is further increased, which may cause leakage of the content vapor from the individual tank. Trouble can be prevented more completely. The slide lid of the coating device according to claim 3 is an individual lid.
Hangs with a hanging bolt on the slide lid via the spring
Since it is peeled off, there is no tilt of the individual lid and the individual tank
It can be sealed under pressure.
