Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cleaning a photographic light-sensitive material processing machine, and more particularly to a method for cleaning a dry belt-shaped photographic material conveying path in a photographic light-sensitive material processing machine. The present invention relates to a method for cleaning a negative film transport path in a negative mask unit.

[0002]

2. Description of the Related Art The presence of dust and dirt adhering to various members constituting a negative film transporting path in a specific example of an auto negative mask unit, such as a guide plate, a guide roller, and a perforation detection hole provided with a glass plate. Causes damage to the film traveling on the path or causes malfunction of detection of various data held by the film. Conventionally, dust, dirt, and the like adhering to the members forming the film transport path of this type of equipment have been cleaned by a maintenance work centered on manual work using a blower brush, waste cloth, and the like.

[0003]

In the conventional manual work-based maintenance using blower brushes, waste cloths, etc., there is a large difference in the removal state of dust and dirt depending on the skill level of the worker. Due to the difference, it was difficult to expect the uniformity. In addition, these maintenance operations require considerable knowledge of machine technology such as disassembly of equipment and subsequent assembly, and this is often subject to great human constraints.

Further, since the film insertion opening and the like provided in the film conveying path in the auto negative mask unit are relatively small in size, a series of maintenance work requires more labor and time than expected. Was. further,
A twin check label for comparison with the DP bag is attached to the film surface of the negative film inserted into the film conveyance path near the tip, and this label-adhering glue constitutes a part of the film conveyance path. ， If it adheres to the guide plate, it is difficult to completely remove it with a simple blower brush. Especially, if this adhesive material adheres to the glass surface laid in the screen detection hole, a negative film is retained. It becomes difficult to detect accurate data.

The present invention solves these various problems by first of all, without being largely influenced by the skill of the operator, by a relatively simple means for cleaning the transfer path of the strip-shaped photographic material in the photographic light-sensitive material processor. The purpose is to propose.

[0006]

In order to achieve the above object, the cleaning method for a photographic light-sensitive material processing machine according to the present invention employs the following construction. That is, the leading side portion of a strip-shaped sheet having high water content and flexibility and having a tough waist is impregnated with a cleaning liquid, and the strip-shaped sheet is supplied from the leading side portion to a conveyance route of the strip-shaped photographic material. It is characterized by being busy. The strip-shaped sheet is made of a non-woven fabric, the wet zone impregnated with the cleaning liquid has a length of about 100 mm, and the subsequent dry zone has a length about 4 times that of the wet zone. As the cleaning liquid, alcohol liquid, water or the like can be used.

[0007]

In the leading end portion of the non-woven strip-shaped sheet substantially corresponding to the width of the strip-shaped photographic material, a sufficient alcohol liquid or water is impregnated by positively utilizing the surface tension of the uneven portion of the non-woven fabric surface. The leading portion of the belt-shaped sheet is supplied into the conveyance path of the belt-shaped photographic material, and the belt-shaped sheet comes into contact with the guide plate, the roller, and the leading edge wet zone of the belt-shaped sheet that make up the conveyance path during the traveling process. , Dust, dirt, etc. adhering to the guide plate, rollers, etc. are sucked up and cleaned, and then the wet residual portion is wiped off using the uneven surface of the subsequent drying zone of the strip-shaped sheet. This operation is repeated at least twice with a single strip sheet. During the second cleaning operation, when the cleaning liquid at the tip leading end is already dry, supply the cleaning liquid and, if necessary, reverse the front and back surfaces of the strip-shaped sheet and repeat the work. Yes. The time required for one cleaning operation at this time is 15 to 30 seconds.

[0008]

Next, more specific embodiments of the cleaning method for a photographic light-sensitive material processing machine according to the present invention will be described with reference to the drawings. The belt-shaped sheet (1) as a cleaning leader for carrying out the present invention has a tough waist portion which is excellent in water content and flexibility, and is especially suitable for folding when the sheet is impregnated with a cleaning liquid. A sheet capable of sustaining no rigidity, for example, a synthetic resin nonwoven fabric, more specifically, a model H-125 polyester fiber nonwoven fabric manufactured by Japan Vilene Co., Ltd., satisfies these requirements. Has a width substantially the same as that of a strip-shaped photographic material, for example, a negative film. As a more specific example, the width is 35 mm and the total length is 50 mm.
The strip-shaped sheet (1) has a length of about 0 mm, and the leading portion of the strip-shaped sheet (1) is sufficiently impregnated with a cleaning liquid such as alcohol liquid or water to form a wetting zone (2) having a length of about 100 mm. A subsequent drying zone (3) of 400 mm in length is formed in the remaining part of the. In addition, the cleaning liquid for this folding is sufficiently impregnated into the fibers of the non-woven strip-shaped sheet, and the surface of the non-woven fabric is also subjected to strong surface tension by using its uneven surface to retain a large amount of liquid and sufficiently. Even when the liquid is impregnated with the liquid, the shape-retaining shape is maintained in the portion.

By using the strip-shaped sheet (1) having the above-mentioned structure, a film conveying path (7) of an auto negative mask unit (6) which is a negative film information detecting device as a specific device of a photographic light-sensitive material processing machine is formed. The cleaning method will be described. The film transport path (7) in the auto negative mask unit (6) is a film insertion opening (8), a strip-shaped guide plate (9) laid along the entire length of the film transport path, and a top surface position of the guide plate (9). A pair of upper and lower guide rollers (10) (10) contacted with each other, a glass plate (11) for perforation detection holes of a film embedded in the guide plate (9) flush with the guide plate, and a guide. A glass plate (12) for screen detection holes of each frame of the film, which is also embedded flush with the plate (9), and a pair of upper and lower guide rollers (13) (13) installed in the inner part of the film transport path. ) And the like, and the total length of the film transport path (7) is 300 to 1000 mm although it depends on the model of the auto negative mask unit.

Using the wet zone (2) impregnated with the cleaning liquid for the strip-shaped sheet (1) as a leading portion, the strip-shaped sheet (1) is inserted through the film insertion opening (8), and the guide rollers (10) and (10). The various members constituting the film transport path (7) are cleaned in the wet zone (2) of the belt-like sheet (1) by the driving of the above, and then the subsequent drying zone (3) is wiped. By repeating a plurality of times, extremely quick and simple cleaning maintenance can be realized in the film transport path.

[0011]

Industrial Applicability The present invention uses a very simple means for feeding and running a cleaning belt-like sheet (cleaning leader) on the ordinary conveyance path of a belt-shaped photographic material. It is possible to expect a uniform cleaning at all times without a large individual difference among workers, and it is not necessary to disassemble and assemble the machine for cleaning and maintenance, which greatly contributes to the improvement of a series of work efficiency. Also, the cleaning of the belt-shaped photographic material conveying path, which is small in location and has many difficulties in its cleaning work, can be performed relatively easily and quickly.
