DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for a cylindrical work, and more particularly, to a cleaning device for cleaning an outer peripheral surface of a cylindrical work such as a cylindrical substrate for an electrophotographic photosensitive member, comprising a cleaning brush. The present invention relates to a cleaning device for a cylindrical work, the cleaning effect of which is improved by the improvement of the above.

[0002]

2. Description of the Related Art For example, in a process of manufacturing an electrophotographic photosensitive member, when a photosensitive material is applied to an outer peripheral surface of a cylindrical aluminum substrate, the outer peripheral surface of the cylindrical substrate is pre-processed. Is washed. In this cleaning step, the cylindrical substrate is held up and down in the axial direction while being held by the chuck device from the inner surface side, and its outer peripheral surface is cleaned with a cleaning liquid using a cleaning brush. As the cleaning brush, a bar-shaped brush which is slidably in contact with a part of the peripheral surface of the cylindrical substrate and is driven to rotate is generally used.

[0003]

Since the bar-shaped brush comes into sliding contact with a part of the peripheral surface of the cylindrical substrate, it is necessary to clean the entire surface of the cylindrical substrate by cleaning the cylindrical substrate. It needs to be driven to rotate in the circumferential direction. For this reason, the conventional cleaning apparatus has a problem that the structure is complicated including the rotation drive mechanism of the cylindrical base. In addition, this bar-shaped brush cannot exhibit a sufficient cleaning function when the flocking density is low. However, when the flocking density is increased, there is a problem that the washed dust easily accumulates in the brush, and the cleaning function is rather deteriorated in a long term.

[0004] The present invention has been made in view of such circumstances, and an object of the present invention is to improve the self-cleaning function of a cleaning brush to maintain a high cleaning function for a long period of time. An object of the present invention is to provide a cleaning device for a cylindrical work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in the cross-sectional view of FIG. 1, a cleaning device for a cylindrical work includes a cylindrical work (1) which is a base of an electrophotographic photosensitive member.
A ring brush (2) is provided as a cleaning brush for cleaning the outer peripheral surface of the cylindrical work (1) in sliding contact with the outer peripheral surface of the cylindrical work (1) from all directions. An injection nozzle (3) is provided above the ring-shaped brush (2) and injects a cleaning liquid onto the outer peripheral surface of the cylindrical work (1).

[0010] The ring-shaped brush (2) is obtained by implanting a brush (2b) on the inner peripheral surface of a base ring (2a). The brush (2b) is made of, for example, nylon in consideration of wear resistance, chemical resistance, and the like, but has a predetermined thickness, length, and length so as not to damage the outer peripheral surface of the cylindrical work (1). It is set to hardness. In addition, the flocking density of the brush (2b) is set to a predetermined low density so as to enhance the self-cleaning function and easily remove even if dust or the like is caught. The brush (2b) may be planted on the entire circumference along the inner peripheral surface of the base ring (2a).
Hairs are intermittently implanted along the inner peripheral surface of a).

In the ring-shaped brush (2), a base ring (2a) is integrated with an inner peripheral side of a ring-shaped gear (4). The ring gear (4) is rotatably supported via a bearing (7) on a support ring (6) fixed to the upper inner surface of a bottomed cylindrical housing (5). Thereby, the ring-shaped brush (2) is rotatable around the axis of the housing (5) together with the ring-shaped gear (4).

The ring gear (4) includes a housing (5).
It is designed to be rotationally driven by a drive motor (8) installed outside via a drive gear (9) and a timing belt (10). The housing (5) has
An opening (5a) through which the timing belt (10) can pass is formed. The rotation speed of the ring gear (4) is set to a predetermined low speed, for example, about 10 to 300 rpm. This is because when the ring-shaped brush (2) rotates at a high speed together with the ring-shaped gear (4), the sliding force of the brush (2b) against the cylindrical work (1) is reduced by centrifugal force, and the cleaning function is reduced. This is to avoid such a situation.

On the other hand, the injection nozzle (3) is constituted by a conduit to a pressure feed pump of a cleaning liquid injection device (not shown) via an opening / closing valve or the like. A funnel-shaped partition plate (11) is provided on the upper inner peripheral surface of the housing (5) so as to partition between the injection nozzle (3) and the ring-shaped gear (4).
Has been fixed.

The cylindrical work (1) is suspended substantially vertically by a transport and suspension device (12) as shown in FIG. That is, the cylindrical work (1) is held from the inner surface side by the chuck device (13) of the transport and suspension device (12) and suspended substantially vertically. The cylindrical work (1) is placed in the housing (5) by the gantry (14) equipped with each chuck device (13) being moved up and down along the column (16) by the elevating device (15). It slides up and down with respect to the ring-shaped brush (2).

Next, the operation of the apparatus for cleaning a cylindrical workpiece according to one embodiment having the above-described structure will be described. In the apparatus for cleaning a cylindrical work, the drive gear (9) and the timing belt (10) are driven by the rotation of the drive motor (8).
The ring-shaped gear (4) is driven to rotate via the ring gear, and the ring-shaped brush (2) integral therewith rotates at a low speed around the axis of the housing (5). By opening an open / close valve (not shown), the cleaning liquid from the pressure pump is injected from the injection nozzle (3).

Therefore, the cylindrical work (1) suspended substantially vertically by the chuck device (13) of the transport suspension device (12) is lowered by the lifting device (15) and set in the housing (5). Into the ring-shaped brush (2). The rotation speed of the ring-shaped brush (2) is set so that the brush (2b) of the ring-shaped brush (2) slides substantially uniformly over the entire outer periphery of the cylindrical work (1). A predetermined low speed is set in relation to the above.

As the cylindrical work (1) passes through the ring-shaped brush (2), the spray nozzle (3) sprays the cleaning liquid on the outer peripheral surface of the cylindrical work (1). The brush (2b) of the ring-shaped brush (2) rotates in the circumferential direction and relatively moves in the axial direction (up-down direction) on the outer peripheral surface of the cylindrical work (1) wet by spraying the cleaning liquid. Touching. Thereby, the outer peripheral surface of the cylindrical work (1) is cleaned over the entire surface.

Here, with cleaning of the cylindrical work (1), dust and the like may be caught in the brush (2b) of the ring-shaped brush (2). However, the brush (2b) has a flocking density set to a predetermined low density, and has a base ring (2b).
Since the bristles are intermittently implanted along the inner peripheral surface of a), dust and the like that are caught are easily removed and do not stay for a long time. That is, the ring-shaped brush (2) has an extremely high self-cleaning function, and thereby maintains a high cleaning function for a long time.

The apparatus for cleaning a cylindrical work according to the present invention is not limited to the above-described embodiment. For example, the cylindrical work (1) may be rotationally driven around an axis by the chuck device (13). In this case, the ring-shaped brush (2) need only be fixed, for example, concentrically to the housing (5), and the drive motor (8), the drive gear (9), the timing belt (10), and the ring-shaped gear (4). ), Etc., the rotary drive mechanism of the ring-shaped brush (2) can be omitted.

Further, the cleaning liquid may be filled in the housing (5) so that the ring-shaped brush (2) is immersed. In this case, make sure that the bearing (7) does not get wet with the cleaning liquid.
The mounting position of the ring-shaped brush (2) on the ring-shaped gear (4) is preferably set below the bearing (7). When the housing (5) is filled with the cleaning liquid, the dirt floating on the surface of the cleaning liquid when the cylindrical work (1) is pulled up from the cleaning liquid is removed from the cylindrical work (1).
May adhere again to the outer peripheral surface of the substrate. Therefore, in this case, it is preferable that the cleaning liquid is sprayed from the spray nozzle (3) to wash off dirt attached to the outer peripheral surface of the cylindrical work (1).

[0021]

As described above, according to the present invention, the ring-shaped brush slidingly contacting the outer peripheral surface of the cylindrical work from all directions rotates relative to the cylindrical work in the circumferential direction,
In addition, with the relative movement in the axial direction, the entire outer peripheral surface of the cylindrical work is uniformly cleaned. For this reason, the ring-shaped brush as a cleaning brush exerts a sufficient cleaning function even if the flocking density is low. Accordingly, the self-cleaning function can be improved by lowering the flocking density of the cleaning brush, and a high cleaning function can be maintained for a long time.

In terms of structure, it is only necessary to provide one of the rotary drive mechanisms for the ring-shaped brush and the cylindrical work, and the other rotary drive mechanism can be omitted, so that the structure can be simplified.
