DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disinfectant dissolving apparatus used for disinfecting a processing solution in a photosensitive material processing tank.

[0002]

2. Description of the Related Art Conventionally, a liquid germicide is supplied into a processing tank in order to sterilize a processing solution in each processing tank of a developing device, particularly, a washing water. However, liquid disinfectants have poor storage properties and require a separate container for disinfectants, which increases costs and causes environmental problems during disposal of the containers.

[0003] In addition, disinfectants in the form of solid tablets are dissolved and stored in a liquid, and the disinfectant which has been dissolved is poured into a treatment tank when necessary. Although a means for inputting after the shape is adopted, the operation on the user side is complicated.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a disinfectant dissolving apparatus which can easily handle and inject a disinfectant into a treatment tank in consideration of the above facts.

[0005]

According to a first aspect of the present invention, there is provided a disinfectant dissolving apparatus for disinfecting a processing solution provided in a replenishment tank for supplying a processing solution to a photosensitive material development processing tank. Holds the disinfectant in the vertical middle of the refill tank
A germicide holding part is provided, and the germicidal material processing tank has a predetermined capacity with the maximum capacity from the highest liquid level.

Exposed to supply replenishing tank outside is a fungicide loading portion, a tubing that is the sterilizing agent holding portion lower end is inserted into the replenisher for the processing solution supply replenisher tank, near the lower end of the tube member provided, it is characterized by having a small opening that is circulated to the sterilizing agent holding portion replenisher of the processing solution supply replenisher tank.

[0008]

[0009]

According to the first aspect of the present invention, the disinfectant in a solid state is gradually dissolved by the treatment liquid when disposed in the disinfectant holding portion. The processing liquid in the processing liquid supply replenishing tank is replenished to the processing tank as the development processing in the processing tank progresses, so that the liquid level decreases. Here, the disinfectant holding part
Is the maximum capacity of the photosensitive material processing tank due to the maximum liquid level.
A state in which the liquid level has dropped due to operation only for the time required for the disinfectant to melt.
Since the liquid level is lower than the liquid level in the state, the disinfectant in the disinfectant holding part has already been dissolved when the liquid level decreases to the disinfectant holding part.

According to the second aspect of the present invention, when the processing liquid in the processing liquid supply replenishment tank is replenished to the photosensitive material development processing tank, the liquid level drops below a predetermined replenishment height, and a warning means is provided. Issues a warning prompting the operator to replenish the processing liquid into the processing liquid supply replenishment tank. However, the disinfectant holding part is located at the position described in claim 1 and
The disinfectant has already been completely dissolved at this warning stage because it is located higher than the required refill height .

According to the third aspect of the present invention, the sterilizing agent in a solid state is supplied from a disinfecting agent input portion at an upper end portion of the tube material exposed to the outside of the processing tank. The disinfectant falls under its own weight in the tube material and is disposed in the disinfectant holding portion at the lower end. Since the disinfectant holding part is in the treatment liquid, that is, the replenisher, the treatment liquid flows through the small opening to the solid disinfectant, and the dissolved disinfectant is dispersed in the treatment tank.

[0012]

[0013] Therefore, the user only needs to put the bactericide in the form of a tablet into the tube material, no preparation is required, and the putting operation is easy.

The disinfectant holding section is preferably disposed at an intermediate portion in the processing tank. If the disinfectant is located near the upper end, the disinfectant is exposed early due to a decrease in the liquid level due to the replenishment of the processing solution to the developing device. In addition, disinfecting of the bactericide becomes insufficient. In addition, if it is near the bottom of the processing tank, the processing liquid in which the disinfectant is dissolved is not sufficiently stirred, only the concentrated liquid precipitates at the bottom of the replenishing tank, and the sufficiently stirred replenishing liquid is not supplied to the processing tank. Will be.

[0015]

1 to 3 show a refill tank 10 for a washing tank to which the present invention is applied. This refill tank 10
Is formed in a hollow box shape having a substantially rectangular horizontal cross-sectional shape, and a rectangular opening 12 is formed in the top surface 10A to supply replenishing washing water. An opening lid 14 is attached to the opening 12 so as to be openable.

The refill tank 10 has a bottom surface 10B.
A drain pipe 16 is communicated with the valve and can be opened by a valve 18. Also, the bottom surface 10B of the refill tank 10
A float switch 22, which is a type of liquid level detecting means, is attached to the bottom surface 10C at a high position from above, and the float 24 moves up and down according to the liquid level, and detects the amount of replenisher below a certain level to detect the amount. A signal is transmitted to a control device (not shown) via the wiring 26, and a warning means such as a display or an alarm for prompting the replenishing tank 10 to replenish the washing water is activated. A pipe 28 communicates with an inclined surface 10D between the bottom surface 10B and the bottom surface 10C, and communicates with a pump that sends the replenisher in the replenishment tank 10 to a photosensitive material washing tank of a developing device (not shown).

A pipe 32 extends through the top surface 10A. The upper end of the pipe 32 is fixed to the top surface 10A via a sleeve 34, whereby the upper end of the pipe 32 is exposed to the outside of the refill tank 10 for washing. The pipe 32 has a vertical axis, a lower end formed with a screw 36 on the outer periphery as shown in FIG. 4, and a nut 38 screwed from the lower end. This nut 38 is
The filter 42 is sandwiched between the lower end of the pipe 32 and the filter 42 and the lower end of the pipe 32 is closed. The filter 42 has a small opening through which the solid germicide 44 or fragments thereof cannot flow, and this small opening is large enough for the replenisher in the replenishment tank 10 to flow. This opening may be single or plural. Instead of the filter 42, the nut 38 may be a cap nut, and a small opening may be formed directly in the cap nut.

Accordingly, when disinfectant 44 is introduced into pipe 32, it is retained by filter 42, and is gradually dissolved by the replenisher flowing and diffused into the replenisher in replenisher tank 10 for washing.

The arrangement of the portion holding the germicide 44 is as follows.
It is preferable that it is located in the middle of the refill tank 10 in the upper and lower portions. That is, if the disinfectant 44 is too close to the upper position of the replenishment tank 10, the disinfectant 44 is exposed on the replenisher as the replenisher in the replenisher tank 10 is supplied to the developing device, and is not sufficiently dissolved. If the disinfectant 44 is located near the bottom surface in the replenishing tank 10 for washing, the dissolved concentrated liquid stays near the bottom surface, and the disinfectant is not sufficiently diffused over the entire area of the replenisher. Further, the pipe 32 is separated from the side wall of the replenishing tank 10 by a predetermined amount so that the disinfectant can be uniformly diffused.

More specifically, the upper and lower positions of the germicide 44 are preferably below the level of the replenisher which decreases from the maximum liquid level while the germicide 44 is completely dissolved. This decreasing replenishing liquid amount indicates the liquid amount when the developing tank of the developing device is operated at the maximum capacity. The maximum liquid level is generally in a so-called full state, which is a position slightly lower than the upper end of the replenishing tank 10, but may be at the upper end of the replenishing tank 10, If there is a maximum liquid level determined by the above, it refers to that height.

Specifically, the dissolution time of the germicide 44 is set to 60
Assuming that the capacity of the replenishing tank 10 for washing is 10 liters, the replenishing rate of the replenishing solution to the washing tank is 180 ml / m ² , and the processing capacity of the photosensitive material of the developing device is 2.5 m / min, the replenishing solution for 60 minutes Is supplied to the washing tank as follows: 2.5 m / min × 60 minutes × 0.152 m × 180 ml / m ² = 4104 ml (1) Therefore, the value obtained by dividing the supplied amount by the cross-sectional area of the replenishing tank 10 is the maximum holding height of the disinfectant. For example, if the cross-sectional area of the replenishing tank 10 is 200 cm ² , Decrease height is 21cm
So, the disinfectant holding position is 21cm from the maximum liquid level
Only at a lower position.

If a warning such as a flush water replenishment alarm is issued immediately after the float switch 22 is actuated,
The position of the disinfectant 44 is higher than the height of the float switch 22, that is, the required refilling height. Further, when a replenishment warning of the washing water is issued after a predetermined time has elapsed after the float switch 22 is operated, the liquid level of the washing water at the time when the replenishment warning is issued, that is, higher than the required replenishment height. A disinfectant 44 is placed at the location.

When this replenishment warning is issued, fresh water may be replenished to the maximum liquid level, and a disinfectant 44 may be supplied from the upper end of the pipe 32.

In FIG. 2, a bleach-fixing replenisher tank 52 and a developing replenisher tank 54 having the same shape are disposed adjacent to the replenishing tank 10 for washing and a bleach-fixing tank of a developing device, respectively. A replenisher is supplied to the developing tank.

Next, FIG. 5 shows a disinfectant holding section according to a second embodiment of the present invention. In this embodiment, the pipe 32
A through hole 64 is formed in a side surface of a nut 62 screwed to a lower end of the pipe 62, and a cylindrical filter 66 is sandwiched between the nut 62 and a lower end of the pipe 32. Thus, in this embodiment, the replenisher is supplied to the filter 66 from the horizontal direction.
Through the germicide 44, so that even when the filter 66 has a large opening, the germicide 44 can be held until completely dissolved.

FIG. 6 shows a refill tank according to a third embodiment of the present invention. In this refill tank, the top 1
0A, a large-diameter cylindrical body 82 is integrally connected with its axis being vertical, and a large number of through holes 8 are formed on the bottom surface of the large-diameter cylindrical body 82.
4 are drilled. A lid 86 is placed over the upper end of the large-diameter cylindrical body 82.

Therefore, by removing the lid 86, replenishing washing water can be supplied into the large-diameter cylinder 82, and the sterilizing agent 44 is supplied into the large-diameter cylinder 82 when supplying the replenishing water or separately. It is possible. In this case, the through hole 84 may have a small opening of the same size as the filter 42 in the first embodiment. In addition, in order to facilitate the passage of the replenishing water, the side of the large diameter cylindrical body 82 has a larger diameter. May be formed in advance.

FIG. 7 shows a refill tank according to a fourth embodiment of the present invention. In this replenishment tank, a protrusion 92 projecting inward is formed at an intermediate portion in the vertical direction, and a perforated plate 94 is placed on the protrusion 92. This perforated plate 9
4 have a large number of through holes 96 formed therein.

Therefore, in this embodiment, similarly to the third embodiment, the replenishing washing water and the disinfectant 44
Can be input.

In the second embodiment to the fourth embodiment shown in FIGS.
This is the same as the embodiment.

It is to be noted that the germicide used in the present invention also includes a sterilizing agent, and the replenishment tank to which the present invention is applied is a series of developing tanks and bleaching tanks of a photosensitive material development processing apparatus for films, photographic paper and the like. It can be applied to any processing tank such as a fixing tank and a washing tank. Further, the filter may be made of any material such as metal or ceramic, and may have another shape such as a wire mesh or a bag. The upper end of the pipe 32 is open. If necessary, a lid for preventing evaporation can be provided at the upper end. In addition, the pipe 32 may be arranged with the axis not inclined but inclined, and the pipe 32 may be formed of a porous material or a mesh material.

The guide means for guiding the germicide from the outside of the replenishing tank to the holding means by its own weight may be in the form of a pipe, but a gutter, rail, or groove sufficient to allow the germicide to fall by its own weight. And so on.

The disinfectant holding part of the present invention is not limited to the porous plate and the filter described in the above embodiment, but is a support that can transmit a treatment liquid and can appropriately hold a solid disinfectant. If so, various materials can be applied.
