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 material processing machine, and more particularly to a method for cleaning a dry belt-like photographic material transporting path in a photographic 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 attached to various members constituting a transport path of a negative film in an auto-negative mask unit as a specific example, for example, a guide plate, a guide roller, a perforation detection hole in which a glass plate is laid, and the like. This may cause damage to the film running on the route or cause malfunction of detection of various data held by the film. Conventionally, dust, dirt, and the like adhering to members constituting a film transport path of this type of equipment have been cleaned by a maintenance work mainly using a blower brush, a waste cloth, and the like.

[0003]

In the conventional manual-based maintenance using a blower brush, a rag, etc., there is a great difference in the state of removal of dust and dirt depending on the skill of the worker, and the maintenance state is also individual of the worker. Due to the difference, it was difficult to expect its uniformity. In addition, these maintenance operations require considerable knowledge of mechanical technology, such as disassembly and subsequent assembly of the equipment, and in this respect, there are often large human constraints.

In addition, since a film insertion opening and the like, which also serve as a working port provided in a film transport path in an auto-negative mask unit, are relatively small, a series of maintenance operations require more trouble and time than expected. Was. further,
A twin check label for comparison with the DP bag is affixed to the film surface near the leading end of the negative film inserted into the film transport path, and the label sticking glue forms a part of the film transport path. , If it adheres to a guide plate, it is difficult to completely remove it with a mere blower brush. In particular, if this adhesive material adheres to the glass surface laid in the screen detection hole, a negative film is retained. It is difficult to detect accurate data.

SUMMARY OF THE INVENTION The present invention solves these various problems by, first of all, a method for cleaning a transport path of a belt-like photographic material in a photographic material processing machine by relatively simple means without being largely influenced by the skill of an operator. The purpose is to propose.

[0006]

In order to achieve the above object, a cleaning method for a photographic material processing machine according to the present invention employs the following constitution. That is, a cleaning liquid is impregnated into a leading side portion of a band-shaped sheet having high water retentivity, flexibility, and tough waist, and the band-shaped sheet is supplied from the leading side portion to a transport path of the band-shaped photographic material. It is characterized by the following. The belt-shaped sheet is made of a nonwoven fabric, the wet zone impregnated with the cleaning liquid has a length of about 100 mm, the subsequent drying zone has a length about four times the wet zone, As the cleaning liquid, an alcohol liquid, water, or the like can be used.

[0007]

The leading end of the nonwoven fabric strip substantially corresponding to the width of the strip photographic material is impregnated with a sufficient amount of alcohol solution or water by positively utilizing the surface tension of the irregularities on the nonwoven fabric surface. The leading portion of the band-shaped sheet is supplied into the conveyance path of the band-shaped photographic material, and in the traveling process, the guide plate and the rollers constituting the conveyance path come into contact with the leading end wet zone of the band-shaped sheet. Then, dust and dirt adhering to a guide plate, a roller, etc. are sucked and cleaned, and then the wet remaining portion is wiped using the uneven surface of the subsequent drying zone of the belt-shaped sheet. This operation is repeated at least twice using a single strip. During the second cleaning operation, if the cleaning liquid at the leading end is already dry, supply the cleaning liquid, and if necessary, turn over the front and back of the belt-shaped sheet and repeat the operation. Es The time required for one cleaning operation in this fold requires 15 to 30 seconds.

[0008]

Next, a more specific embodiment of the method of cleaning a photographic material processing machine according to the present invention will be described with reference to the drawings. The strip-shaped sheet (1) as a cleaning leader for carrying out the present invention has excellent water-containing properties, flexibility and a strong waist, and is particularly suitable for folding a sheet impregnated with a cleaning liquid. For example, a nonwoven fabric made of synthetic resin, more specifically, a nonwoven fabric made of Nippon Vilene Co., Ltd., model H-125 polyester fiber satisfies these requirements. Is about the same width as a strip-shaped photographic material, for example, a negative film. As a more specific example, the width is 35 mm, and the overall length is 50.
The leading edge of the strip-shaped sheet (1) is sufficiently impregnated with a cleaning liquid, for example, an alcohol solution or water, to form a wet zone (2) having a length of about 100 mm. Is formed with a moisture wiping drying zone (3) having a length of 400 mm. In addition, the liquid for cleaning in this fold is sufficiently impregnated into the fibers of the nonwoven fabric band-like sheet, and a strong surface tension is applied to the surface of the nonwoven fabric by using the uneven surface thereof, so that a large amount of liquid is retained and sufficient. Even when the liquid is impregnated, the shape is maintained without breaking.

Using the belt-shaped sheet (1) having the above structure, a film transport path (7) of an auto-negative mask unit (6) as a negative film information detecting device as a specific device of a photographic material processing machine. The cleaning method will be described. The film transport path (7) in the auto-negative mask unit (6) is a film insertion port (8), a strip-shaped guide plate (9) laid over 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) and (10), which are configured in contact with each other, a glass plate (11) for a perforation detection hole of a film buried flush with the guide plate on the guide plate (9); A glass plate (12) for a screen detection hole of each frame of the film, which is also buried flush with the plate (9), and a pair of upper and lower guide rollers (13) (13) installed at the back of the film transport path. ), And the total length of the film transport path (7) is 300 to 1000 mm depending on the type of the auto negative mask unit.

With 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 from the film insertion opening (8), and the guide rollers (10) and (10) are inserted. 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 belt, and then wiped in the subsequent drying zone (3). By being repeated a plurality of times, extremely quick and simple cleaning maintenance can be realized on the film transport path.

[0011]

According to the present invention, dust, dirt and the like adhered to various members constituting the conveying path by a very simple means for feeding and running a cleaning belt-shaped sheet (cleaning leader) to the conveying path of the ordinary band-shaped photographic material. Can be expected to perform uniform cleaning at all times without significant individual differences between workers, and there is no need to disassemble and assemble the machine for cleaning and maintenance, which greatly contributes to the improvement of a series of work efficiency. In addition, the cleaning of the belt-like photographic material transporting path, which is narrow in space and has many difficulties in the cleaning operation, can be performed relatively easily and quickly.
