。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gripping device for a cylindrical body. Specifically, the present invention provides a method for gripping a cylindrical body and immersing it in a liquid.
The present invention relates to a gripping device that can grip a cylindrical body without contacting the outer surface of the cylindrical body and prevents liquid from wetting the inner surface of the cylindrical body. In particular, the present invention relates to a drum gripping device suitable for applying a photoreceptor layer to the outer surface of a photoreceptor drum during the production of an electrophotographic photoreceptor.

にするのが好捷しい。One method for applying a photoreceptor layer to a drum is to suspend and immerse the drum in a photoreceptor solution. In this method, a coating film is not formed at the gripping point of the drum, that is, the contact area between the drum and the gripping device, so if the drum is not gripped at a point other than the outer surface on which the photoreceptor layer is to be formed, the drum will be exposed when immersed. Preferably, the solution does not come into contact with the inner surface of the tube.

される液膜の均一性を阻害するので好ましくない。As a device that satisfies such requirements, the present inventors have previously proposed (al) rod (b+ mechanism for suspending and supporting the rod (cl) a fluid-tight bag attached to the lower end of the rod and capable of expanding and contracting. A gripping mechanism Fdl having a portion is equipped with a fluid discharger mechanism that introduces and discharges fluid into the bag portion to inflate and deflate it, and the bag portion of the gripping mechanism proposed a device characterized by being able to tightly grip the inner wall of a cylindrical body and at the same time block the flow of gas inside the cylindrical body (June 1981). (Refer to Patent Application No. 190, "Cylinder gripping device") This device grips (chucks) the drum inside, and when the drum is gripped and vertically immersed in liquid, the side wall of the drum and the gripping device The inner surface of the drum is superior in that its lower end is only slightly in contact with the liquid, since the air in the space formed by the drum prevents liquid from entering this space. When the drum is gripped by the device, dipped vertically into the liquid, and then pulled vertically out of the liquid, the air trapped inside the drum becomes bubbles just before the drum leaves the liquid surface. The bubbles may be ejected from the lower end of the drum and adhere to the outer surface of the drum.This adhesion of air bubbles to the outer surface of the drum is undesirable because it impairs the uniformity of the liquid film formed on the outer surface.
この気泡の放出は、ドラムが液体中に浸漬されている間
に液体が蒸発して、ドラムの内側の空間のガス量が増加
したことによるものと推定される。すなわち、ドラムの
内側の空間にはもともと大気圧の空気が存在しているが

ドラムを引上げて行くと液体の圧力が減少し、ついには

力が犬となら、ドラムの内側の空間部から外部に気泡が
放出されるに至るものと思われる。It is presumed that this release of air bubbles is due to the liquid evaporating while the drum was immersed in the liquid, increasing the amount of gas in the space inside the drum. That is, although air at atmospheric pressure originally exists in the space inside the drum, the amount of gas in the space inside the drum increases because the vapor generated from the liquid during the dipping operation is added to this air. While the drum is immersed to a sufficient depth in the liquid, the gas is confined in the space because the pressure of the liquid is greater than the pressure of the gas in the space containing the generated vapor. However, as the drum is pulled up, the pressure of the liquid decreases, and eventually the pressure of the gas in the space containing the generated vapor exceeds the pressure of the liquid, and bubbles are released from the space inside the drum to the outside. It is thought that this will lead to
本発明はドラムの内側の空間部の圧力を制御することを
可能とする把持装置を提供するものである。The present invention provides a gripping device that makes it possible to control the pressure in the space inside the drum.

特徴とするものである。That is, the present invention is a gripping device for a cylindrical body for gripping a cylindrical body and immersing it in a liquid so that only the outer surface of the cylindrical body comes into contact with the liquid. A mechanism for suspending and supporting (cl
A gripping mechanism (dl) is attached to the lower end portion of the rod and has a fluid-tight bag portion that can be inflated and deflated.
A discharger mechanism (θ) for the fluid to be contracted is equipped with a pressure adjustment mechanism having a hole passing through the gripping mechanism up and down, and the bag portion of the gripping mechanism has a cylindrical shape when inflated inside the cylindrical body. It is characterized by being able to tightly grip the inner wall of the body and to prevent the flow of gas inside the cylindrical body through parts other than the pressure adjustment mechanism.
本発明についてさらに詳細に説明すれば、本発明は筒状

側から把持する装置である。To explain the present invention in more detail, the present invention is an apparatus for gripping a cylindrical body from the inside using a gripping mechanism that engages with the inner wall of the cylindrical body by frictional force.

放出を防止できる。Therefore, when a cylindrical body is gripped and suspended in the liquid using the apparatus according to the present invention, since the gripping mechanism does not contact the outer surface of the cylindrical body, the entire outer surface can be brought into contact with the liquid. In addition, in the inner space of the cylindrical body below the gripping mechanism,
Due to the pressure of the gas trapped in this part, almost no liquid enters, so neither the inner wall of the cylindrical body nor the gripping mechanism itself comes into contact with the liquid. Furthermore, since the pressure in the inner space of the lower cylindrical body can be adjusted from the gripping mechanism,
Air bubbles can be prevented from being released from the inner space when the cylindrical body is pulled up from the liquid.
本発明を図面に基づいて具体的に説明すれば、第1図は

ている)。In the figure, (11 is a rod, and the inside is hollow. (2) is the bottom plate of the cylinder (3). The cylinder (3) has almost the same shape as the inner surface of the cylindrical body (7). , can be freely inserted into the cylindrical body (7). (4) is an annular groove provided on the outer surface of the cylinder (3), and (5) is an annular rubber bag accommodated in this groove. Yes. (6) is a rod (1) and a rubber bag (5)
This is the supply and exhaust pipe that connects the (8) is a hole penetrating the bottom plate (2). (9) is a pipe communicating with the hole (8), and (lO) is a valve provided in the middle of the pipe (note that the means for controlling the opening and closing of the valve is omitted in the figure. ).

ず、結果的に外表面だけが液体と接触する。To explain how to use this device, with the rubber bag (5) deflated and the valve (10) closed, the cylinder (31
vertically inserted halfway into the cylindrical body (7). Next, when air is forced into the rubber bag (5) through the rod (1), the rubber bag (5) expands and comes into close contact with the groove (4) and the inner wall of the cylindrical body (7), thereby forming a contact with the cylinder (3). The flow of air between the tubular body (7) is blocked. When the air pressure inside the rubber bag (5) is raised sufficiently, the cylindrical body can be suspended by the rod (1) due to the frictional force between the rubber bag (5) and the inner wall of the cylindrical body. In this state, the cylindrical body is suspended and vertically immersed in the liquid. Since air is confined in the space (marked) at the bottom of the cylindrical body, almost no liquid can enter this space, and as a result, only the outer surface comes into contact with the liquid.
次いで、この状態から筒状体を垂直に引」二げてゆくと

にすぎない。この状態で筒状体の引上げを続行すると、
空間部分(11)から気泡が放出されることなく、筒状
体を液面上に引−Fげることができる。Next, when the cylindrical body is vertically pulled out from this state, the pressure in the space (11) gradually decreases, so that
The liquid level that has entered the inside of the cylindrical body against the air pressure in the space part (marked) gradually decreases. Just before this liquid level reaches the bottom end of the cylindrical body, the valve (10) is opened and the space part ( 11) is communicated with the outside to equalize both pressures.At this point, the cylindrical body is only slightly immersed in the liquid, so even if the valve is opened, the liquid will not flow inside the cylindrical body. It only penetrates slightly.If you continue to pull up the cylindrical body in this state,
The cylindrical body can be pulled above the liquid surface without air bubbles being released from the space (11).
上記の方法においては、弁(10)の開放時期の選択が
重要であり、早過ぎると液体が多量に筒状体の内側に侵
入して、内壁に接触する。逆にこれが遅すぎると、気泡
の放出がおこる可能性がある。通常は、筒状体の浸漬深
さが所定の値に達したときに弁を開放するようにする。In the above method, the selection of the opening timing of the valve (10) is important; if it is too early, a large amount of liquid will enter the inside of the cylindrical body and come into contact with the inner wall. Conversely, if this is too slow, bubble release may occur. Normally, the valve is opened when the immersion depth of the tubular body reaches a predetermined value.
この値は浸漬時間および液体の蒸気圧により決定すれば
よいが、通常は10@m以下である。好ましい操作方法
の一つは、筒状体を一定速度で引上げ(゛または、ロッ
ドを固定して液体を入れた容器を一定速度で降下させ)
、引上げ速度から計算して浸漬深さが所定の値に達する
時点で弁(10)を開放するように自動制御手段を設け
ることである。This value may be determined by the immersion time and the vapor pressure of the liquid, but is usually 10@m or less. One of the preferred operating methods is to pull up the cylindrical body at a constant speed (or, fix the rod and lower the container containing the liquid at a constant speed).
, an automatic control means is provided to open the valve (10) when the immersion depth reaches a predetermined value calculated from the pulling speed.

ことができる。Another method of using the device shown in Figure 1 is to connect the tube (9) with pressure-reducing means so that when the cylindrical body is immersed in a liquid, a space is removed from the pressure source depending on its depth. Air is forced into the space (11), and when the cylindrical body is pulled up from the liquid, the tube (9) is connected to a decompression source, and the space (11) is
1) Exclude the air so that the liquid level is always slightly inside the lower end of the cylindrical body. According to this method, it is possible to limit the contact of the liquid to the inside of the cylindrical body only in the very vicinity of the lower end.

とはない。Another way to use the device shown in Figure 1 is to suspend the cylindrical body with the valve (10) open, lower it vertically, and close the valve 00) just before the cylindrical body contacts the liquid level. This is the way to close it. According to this method, the air in the space of the cylindrical body (marked) is replaced one after another during its descent at the liquid level, and finally has almost the same composition as the air near the liquid surface. -7S
As described in O'l/, if the side wall of the container extends from the liquid surface to one side and the air near the liquid surface is saturated with liquid air, this method Since the air in the space (marked) contains a considerable amount of liquid vapor when it reaches the liquid surface, the vapor generated from the liquid during immersion is suppressed from accumulating in the space.This suppression Depending on the extent of this, air bubbles will not be released from the space (11) even if the valve (10) is not opened when the cylindrical body is pulled up from the liquid.

小さくするのが好ましい。In the device shown in Fig. 1, annular rubber bags (5) are housed in the upper and lower grooves of the cylinder (3), but instead of the rubber bags, the openings of the grooves may be airtightly covered with a rubber membrane. It has a similar effect. In addition, in order to hold the cylindrical body vertically in this device, it is preferable to make the distance between the cylinder () and the cylindrical body (7) as small as possible.

12) is attached. Of course, a disk-shaped hollow body (16) having a rubber membrane (15) and a side wall formed of a comb membrane (I2) is provided, and an attitude control member (16) is provided above it.
3). This member has a layer shape on the outer surface of the lid that fits into the cylindrical body, and has a layer shape on the outer surface. When inserting the holding mechanism into the cylindrical body and gripping the cylindrical body, the shoulder portion contacts the two ends of the cylindrical body, and the portion reaching the shoulder serves as a guide, and the cylindrical body and the rod are coaxial. (18) is a through hole for ventilation provided in the attitude control member.

Further, since the relative relationship between the rod and the cylindrical body is controlled by both the hollow body and its ten attitude control members, the cylindrical body can be gripped vertically. In addition,
