Abstract

PURPOSE:To reduce the manufacture cost by providing piping of only one system to the washing tank or supplementary water tank of the developing machine as feed water piping directly from a stopcock of city water. CONSTITUTION:The supplementary water tank 80A is provided nearby above the washing tank 30 and city water is injected into the tank from the stopcock through a pipe 4, a filter 5, a pipe 6, a solenoid valve 7, and a pipe 8. The water reserved in the supplementary water tank 80A is injected into the adjacent washing tank 30 whose overflow water level H1 is lower than H2. Then a pipe 82A projects from the bottom part of the supplementary water tank 80A to inject supplementary water into a developing tank 10 through a pump 83A and a pipe 84A, also inject supplementary water into a fixing tank 20 through the pipe 82A, a pipe 85A, a pump 86A, and a pipe 87A, and further inject supplementary water into the humidifying water tank 51 of the humidifying device through the pipe 82A, a pipe 88A, a pump 89A, and a pipe 91A. Consequently, the efficient water feeding method which reduces the manufacture cost of the automatic developing machine is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a method for supplying water to an automatic developing machine for photosensitive materials.

[Conventional technology]

Conventionally, the automatic developing machine 1 has a supply stage 2. Developer tank lo.

Fixing tank 20. Washing tank 30. Dry ff140. As a means for supplying replenisher to the sonohumidifying device 1150° recovery unit 3 and multi-tank, a developing stock solution replenishment tank 60. It has a fixing stock solution replenishment tank 70° and a replenishment water tank 80 for density adjustment water.

And the water from the tap is pipe 4. Filter 5. Vibro, solenoid valve7. It is injected into the washing tank 3° via the pipe 8. Further, from the vibro, a vibro A is branched off, connected to a solenoid valve 9, and further injected into a replenishment water tank 80 through a pipe 9A. The washing tank 30 is provided with an overflow port to appropriately replace the washing water.

The developer stock solution replenishment tank 60 supplies the vibro 2.0 to the developer tank IO. Pump 63. A developing solution is injected by the vibro 4 and is supplied from a replenishment water tank 80 to a pipe 82. pump 83,
Replenishment water is injected through a pipe 84.

Similarly, a pipe 72. Pump 73. A fixing stock solution is injected through a pipe 74, and is transferred from a replenishment water tank 80 to a pipe 85. Bonda 86
．． Replenishment water is injected through a pipe 87.

Further, the humidifier 150 of the drying section 40 includes a replenishment water tank 8.
0 to pipe 88. Pump 89. Replenishment water is injected through a pipe 91.

The above is based on one type of developer and constant tank liquid, but depending on the photosensitive material, the developer and fixer may be A or B, respectively.
Some require the use of two liquids. In that case, the number of processing tanks will be doubled, and the replenishment tanks for each replenisher, their piping, and pumps will also be doubled.

FIG. 12 shows another example of a conventional method for supplying water to a humidifying water tank. Water supplied from tap water is filtered5. After passing through the flowmeter 5A, the water is branched into the machine water supply and the humidifying water tank water supply, and the humidifying water tank water supply is connected to the solenoid valve 9A, the deionizer 35. Water is supplied to the humidifying water tank 51 through the constant flow valve 9C and through the ball tap 53 (or solenoid valve).

The water in the humidifying water tank is atomized by the ultrasonic vibrator 54 and humidified.

The water purifier 35 prevents ionic components contained in tap water from turning into white powder and adhering to the inside of the drying section or onto a film or the like.

The constant flow valve is set so that the water supply flow rate is higher than the maximum flow rate of the humidifier and lower than the allowable overflow amount from the overflow roller 52 of the humidifying water tank 51,
This prevents water from overflowing from the humidifying water tank when the pole tag 53 or solenoid valve loses its liquid level control function.

[Problem to be solved by the invention]

In the automatic developing machine configured as described above, the replenishment water tank is arranged side by side with the replenishment tank for each processing stock solution, so the water supply piping of the water pipe is done in two systems, the washing tank and the replenishment water tank, which increases the number of piping steps.

That is, a solenoid valve must be provided in each piping system to separately control the water supply to the washing tank and the replenishment water tank. For this purpose, the replenishment water tank must be equipped with a liquid level detection switch and an overflow device in the same way as the washing tank, which makes the device complicated. Furthermore, if the replenishment water tank does not have an overflow device and the solenoid valve malfunctions, accidents such as water leakage and other difficult handling may occur.

Furthermore, if there are two systems of water supply piping from the water faucet, it becomes difficult to move the replenishment liquid tank and pump set around the replenishment water tank, and maintenance and inspection work becomes difficult. This is true whether the tanks for replenishment water and replenishment stock solution are built into the automatic processor or provided externally.

Further, as shown in FIG. 12, when a humidifying device for the drying section and its water supply piping are added to the automatic developing machine, the number of water supply piping is further increased.

An object of the present invention is to solve these problems and provide an efficient water supply method for an automatic processor.

A replenishment water tank is provided between the tank and the water supply pipe, and an outlet of the replenishment water tank is located at a position that prevents the water in the washing tank from flowing back into the replenishment water tank with respect to the overflow water level of the washing tank. Automatic development characterized by having a structure in which water in the replenishment water tank is injected into the washing tank, so that water is replenished from the replenishment water tank to each of the processing tanks and the humidification water tank as necessary. How to supply water to the machine.

(2) An automatic developing machine having a built-in or connected water replenishing device for at least one of the processing liquid tanks for development, bleaching, and fixing and the humidifying water tank of the drying section, and a separation processing device for each of the processing liquids, and washing with water. Water is supplied directly to the washing tank, and water is replenished to the developing tank, each processing tank for bleaching and fixing, and the humidifying water tank in the drying section by draining the washing water from the washing tank and adding an ion exchange agent and adsorbent in the middle of the piping. 1. A water supply method for an automatic developing machine, characterized in that the water supply method is carried out by providing at least one of a filler and a pure water device including at least one of the following.

〔Example〕

The embodiment of the method of the first invention is shown in the general view in FIG. 1, in FIG.
FIG. 8 is a connection diagram of the washing tank and the replenishment water tank in FIGS. 3, 4, 5, 6, and 7.

This will be explained with reference to the connection diagrams of the humidifying water tank and water supply shown in FIG. 9 and FIG. 1O. In these figures, members having the same functions as those of the conventional example are indicated by the same numbers. Furthermore, the method of the present invention is not limited to this example.

As shown in FIG. 1, an automatic processor IA using the method of the first invention includes an exposed film supply stand 2. Developer tank 10. Fixing tank 20. Washing tank 30. Drying section 40. The humidifier R50
A developer stock solution replenishment tank 60 and a fixing stock solution replenishment tank 70 are provided as replenisher tanks for the first collection unit 3 and various types. The developer tank 10 is supplied with a vibro 2. Pump 63. The developer stock solution is injected via the vibro 4, and the fixing tank 20 is similarly connected to a pipe 72. Pump 73.
The fixing stock solution is injected through the pipe 74.

The replenishment water tank 80A is provided close to the upper part of the washing tank 30, and is connected to a water tap, a pipe 4, a filter 5. Vibro, solenoid valve7. Tap water is injected via pipe 8.

The water stored in the replenishment water tank 80^ is lower than its overflow water level H1, and the overflow water level provided adjacent to it is H! It is intended to be injected into the wash tank 30 which has a lower Hl. Therefore, there is no backflow from the washing tank to the replenishment water tank. A pipe 82A comes out from the bottom of the replenishment water tank 80A, and a pump 83^ and a pipe 84
This allows replenishment water to be injected into the developer tank 1G via A. Also, from the middle of pipe 82^, pipes 85A and 88
A is branched. And pipe 82^, pipe 85A
Similarly, replenishment water can be injected into the fixing tank 20 through the pump 86A and the pipe 87A, and the replenishment water can be injected into the humidifying water tank 51 of the humidifying device 50 of the drying section 40 through the pipe 82A, the pipe 88A, the pump 89A, and the pipe 91. It is possible to do so.

As shown in FIG. 2, a replenishment water tank 80A is provided in the washing tank 30 so that oats (-fluoro 32) is formed and the water level of the nuclide 30 is maintained at H, and the water level is set at Hl higher than Hl. As described above, the pipe 82A comes out from the bottom of the replenishment water tank 80^, and replenishment water can be injected into each processing tank or humidifier through each pump.

At the same time, a drainage pipe 92 may be provided from the bottom of the replenishment water tank 80A, if necessary, and a valve 93 may be provided in the pipe. The valve may be manual or electrically operated.

The water in the replenishment water tank may be drained continuously without installing the valve. In this case, it is preferable that the amount of water supplied to the replenishment water tank is at least twice the amount of water discharged from the replenishment water tank. By providing the replenishment water tank with a drainage mechanism, it is possible to prevent the replenishment water tank from becoming contaminated with water stains.

In addition, as shown in FIGS. 3, 4, 5, and 6, water is poured into the washing tank 30 of the replenishment water tank 80A from the overflow surface H1, and at the same time, water is poured into the bottom or side of the replenishment water tank 80A. It is also possible to make a water injection hole through which the water can be poured into the washing tank via a pipe or directly.

This makes it possible to return the wastewater from the replenishment water tank to the flush tank, thereby eliminating wasteful draining from the replenishment water tank.

Since the overflow water level H3 of the replenishment water tank is higher than the overflow water level H5 of the replenishment water tank, the injection hole of the replenishment water tank to the washing tank is connected to the overflow water level H1 of the washing tank.
It is desirable that it be slightly above. Apart from that, it is desirable that the amount of washing water from the washing tank is at least twice or more, preferably five times or more, the amount of water supplied to the developing tank, fixing tank, and humidifying water tank.

Also, as shown in FIG. 7, the replenishment water tank 80A is placed in the washing tank 30 with the upper surface of the tank 80A higher than the overflow surface H8 of the $130, and the tank 80A is placed there.
An inlet from a water tap may be provided to the tank 80A, and a drain port may also be provided at the bottom of the tank 80A.

Then, the overflowing water is removed from the overflow port 3.
2 to maintain the water level H in the washing tank 30.

Further, as shown in FIG. 8, replenishment water from the replenishment water tank 80A is supplied to the humidification water tank 51 of the humidifier 50 through a pipe 91.
Water is transported through the Then, the liquid level is controlled by the ball tap 53 (or solenoid valve). Furthermore, by setting the liquid level of the humidifying water tank at a lower level than the liquid level of the replenishing water tank, water supply means such as a pump for the humidifying water tank becomes unnecessary.

Furthermore, if the flow rate from the replenishment water tank is set to be smaller than the allowable overflow rate, a constant flow valve that maintains a constant flow rate regardless of the water pressure is not required, which is a good idea. Also, of course, water piping to the humidifying water tank 5 becomes unnecessary. In this way, the ultrasonic vibrator 54 provided at the bottom of the humidifying water tank 5 can stably humidify the drying section 40.

In addition, as shown in the tJgo diagram, an overflow roller 52 having a height of over 7o is set at the position of the control liquid level of the humidifying water tank 51, and the amount of replenishment water injected is larger than the maximum atomization amount of the humidifier 5o. Furthermore, if the allowable overflow amount is made larger than that, water supply adjustment means such as a ball tap or a liquid level sensor and a solenoid valve as shown in Fig. 8 become unnecessary.

Of course, a method of replenishing water using a pump as shown in FIG. 10 is also possible.

8th~IOI! In method 1, a water purifier or the like may be inserted in the middle of the water supply piping to the humidifying water tank in order to prevent white powder from forming in the drying section.

Next, an embodiment of the second invention will be described using FIG. 11.

This is done by removing the replenishment water tank 80A from the overall diagram of the first invention shown in FIG. Purifier 35 using exchangeable resin, adsorbent, filter, etc.
and pumps 83A and 86A similar to those shown in FIG. 1 to each treatment tank and humidification water tank.

This is the method of connecting 89A. As a result, the washing tank 3
Clean water from which fixing and developing solution components mixed with the washing water and impurities contained in tap water in some cases have been removed is supplied as replenishment water, and good water replenishment can be stably obtained.

〔Effect of the invention〕

With the present invention, the direct water supply piping from the water faucet can be completed with only one line of piping to the washing tank of the developing machine or the replenishment tank installed close to the washing tank, instead of two or more lines as in the past. It is no longer necessary to move the developing machine 1°, and it becomes easier to move the developing machine. Additionally, the number of solenoid valves has been reduced, simplifying flow control, lowering production costs, and making operation easier.
