Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fluid injection method and a fluid injection device for injecting a fluid into a plurality of containers.

[0002]

BACKGROUND OF THE INVENTION Many laboratories, factories, industrial facilities and shops require fluids, usually waste liquids, that are discharged from equipment or equipment that uses the fluids and collected systematically for reuse. And

For example, in the photographic processing industry, a processing apparatus for developing a film and printing the developed negative is used. Often such devices are called minilabs or microlabs. These minilabs require many chemical solutions, including developers, bleach, bleach-fix, and the like. The chemical solution supplied to the processing apparatus is discharged as a process overflow.

[0004] Conventional equipment for collecting process overflows from minilabs or microlabs requires frequent operator attention to ensure that the collection means is sufficient and that the overflow does not overflow.

Therefore, there is a need to reduce the number of operators who manage the daily operation of equipment that must be patrolled daily for maintenance (removing full collection means, eg containers, replacing with empty collection means). Have been.

The above requirements require, for example, that only full waste collection containers provided by waste collection (ie, those containing chemical waste discharged from an operating processing unit) be removed. Become. The operator treats partially full containers as well as fully filled containers, but partially filled containers should not be replaced. If this can be done, the ability to collect effluents discharged during the day is guaranteed.

[0007]

First of all, a method which can solve the above-mentioned problem and can be easily conceived to perform the above-mentioned operation will be described, and its problems will be described.

For example, if an operator collects an average of 18 liters of process waste per day (process overflow) from a processing unit having a maximum capacity of less than 24 liters, at least three standard 10 liter containers are required. Distinguish the above three containers from A, B, C,
Placing them at different heights from the ground, filling the container with the lowest height from the ground first, filling the second lowest container second, and filling the highest container last is simple. Means.

As described below, in the above arrangement, if only the filled container is removed and replaced with an empty container, the ability to collect waste liquid discharged daily from the processing apparatus is secured every day. Can not do.

In the following example, the waste liquid discarded from the apparatus is 1
It is assumed that the operation of replacing the full container with an empty container is performed once a day, at the beginning of the day, at the end of the day, or at a fixed time of the day.

[0011]

[Table 1]

At the end of the fourth day, it can be seen from the above example that the system causes a 2 liter overflow. If such an overflow occurs when there is no operator in the processing unit, it will damage the inside of the processing unit and the surrounding area.

[0013] It is an object of the present invention to provide a method and apparatus for automatically injecting fluid into a container that first fills a partially filled container to prevent overflow from occurring. That is.

[0014]

According to a first aspect of the present invention, there is provided a fluid injection device for automatically and repeatedly injecting fluid into a plurality of containers, wherein the fluid is injected before the fluid is injected into an empty container. Provide means for injecting fluid preferentially until the container fills the partially filled container.

It is preferable that each of the containers can be vertically displaced within a range in which the containers can be freely installed.

In one embodiment, each container is interdependent on its vertical arrangement. In the above embodiment, the injection device according to the present invention is provided with a container platform that freely pivots around a pivot point provided in the center, and is mounted at a distance from the center of the container platform so as to be detachable from the container platform. And a fluid link from each container to a central common fluid inlet that follows the movement of the container platform when the container platform turns.

Means are provided to facilitate tilting the platform in a known direction, by gravity,
When the platform is tilted in any downward direction, all containers are individually vertically displaced. Such means may be a plurality of legs extending below the platform and / or weights mounted on the platform.

Preferably, the legs are adjustable in expansion and contraction, and the weight is adjustably mounted. In addition, by attaching at least one of the leg and the weight separately to the platform, the vertically displaced container is inclined to one side, and another container is displaced on a vertically continuous slope. The container may be effectively tilted so that it is positioned in a staggered manner.

In accordance with another aspect of the present invention, there is provided an injection device including a container removably mounted on a biasing means for vertically displacing the container when the container is empty. Is done.

The bias means is preferably a plurality of springs or pivot balances.

When a plurality of springs are used, the springs are of different length and different strength so that when all containers are empty, the detachably mounted containers are transposed separately vertically. At least one must be retained. Further, the partially filled container is positioned vertically below the empty container, and the full container is positioned vertically below the partially filled container. It is necessary to provide appropriate flexibility and length to provide appropriate mobility.

When a pivot balance is used, the pivot balance may include a disposition frame for attaching a detachably mounted container at one end and a weight at the opposite end. When the container is empty, the weight is sufficient to balance the weight of the container, so the empty container is positioned highest in the vertical direction, but when the container is full or partially filled with fluid, the weight Is not well balanced with the weight of the container, the full container and the partially filled container being positioned vertically lowest.

In the injection device according to the present invention, a fluid link from each container to the central common fluid introduction portion, which is separately transposed vertically in accordance with each container,
It may be provided.

[0024] The central common fluid inlet may be installed on a slope configuration for a plurality of containers. By doing so, the relative transposition of each fluid link connecting portion to the introduction portion in the vertical direction is continuously reduced along the slope applied to the introduction portion.

If necessary, a means for regulating the flow of the fluid to be injected into the container may be provided so that the fluid is preferentially injected into the partially filled container prior to the injection into the empty container. May be. Further, means may be provided for adjusting the total volume of fluid that can be injected into the container.

According to another aspect of the invention, when the containers are empty, the containers are each separately vertically displaced relatively.

The fluid preferably used in the injection device according to the present invention is a liquid. For example, the fluid is waste liquid from a photographic processing device.

The container which is preferably used in the injection device according to the invention is a cuboid shaped container of moderate volume, for example the Eurostacker ^™ class. It goes without saying that "Jerry Cans" or the like may be used as a modified example. Usually, the containers are stackable, but may be formed from a general bottle type (which may or may not be stackable). The container preferably has a volume of 5 to 20 liters so that the containers can be individually lifted.

According to yet another aspect of the present invention, there is provided a fluid injection method for continuously and automatically injecting fluid into a plurality of containers along an injection sequence, the method comprising: A preferential infusion of fluid is provided until the container is partially filled with fluid.

It is preferable that the containers can be individually transposed in the vertical direction as long as the containers can be freely installed.

In the fluid injection method according to the present invention, the injection sequence includes the step of filling the first container partially filled with the empty or fluid displaced at the lowest position with respect to another empty container. Injecting fluid into the first container until it is full and filling the second container until the second container displaced lower than another container that is empty is filled or at least partially filled with fluid. Need to inject fluid.

If the second container is full of fluid and no fluid is consumed, the above fluid sequence is repeated and fills or partially fills an empty container that has been displaced vertically lower than another container. Until the fluid is filled, the fluid is injected into the container.

By the above method, the container filled with fluid is removed without interrupting the injection sequence,
Can be replaced with an empty container.

The injection sequence preferably lasts indefinitely.

The container may be interdependent on its vertical transposition.

By means of a fluid link to the first container, which is positioned vertically lower than another empty container, until the first partially filled or empty container is filled with fluid, By releasing the fluid through the central common fluid inlet, the above infusion sequence is achieved, forcing the fluid from the central common fluid inlet to stagnate, and another empty container via the second fluid link. The second is positioned relatively lower in the vertical direction than
May be poured into empty containers.

If the second container is full of fluid and is not consumed, the injection sequence is repeated, forcing the fluid from the central common fluid inlet to stagnate and in a more vertical direction than another container. Fluid is injected into the third container until the relatively lower third container is full or partially full.

When one or more containers are full, it is possible to remove the full containers from the infusion sequence and replace them with empty containers without interrupting the infusion sequence. Also, the partially filled container is preferably not removed.

The fluid used in the fluid injection method according to the present invention is preferably a liquid.

The container preferably used in the injection method according to the present invention is a cuboid with a moderate volume, for example a container of the Eurostacker ^™ class. It goes without saying that "Jerry Cans" or the like may be used as a modified example. Usually, the containers are stackable, but may be formed from a general bottle type (which may or may not be stackable). The container preferably has a volume of 5 to 20 liters so that the containers can be individually lifted.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
An injection device and an injection method according to the present invention will be described.

Referring to FIG. 1, an injection device 2 according to the present invention will be described. The injection device 2 includes a base plate 10 having a pivot arrangement 32 (not shown in FIG. 1) in the center of the back. The container platform 4 is provided on the pivot arrangement 32, and can freely rotate around the pivot arrangement 32 installed at the center.

The container platform 4 is preferably designed to maintain at least one axis of symmetry to facilitate the operation of the tilt mechanism and consequently the operation of the injection sequence.

In the embodiment of the invention shown in FIG. 1, the legs 5, 6 provided at the edge of the container platform 4 serve as pivot points. Each leg includes a bracket assembly 5A, 6A,
B, 6B and feet 5C, 6C. One leg 5 is provided at the center of the longitudinal edge of the container platform 4, and the other leg 6 is provided at the container platform 4.
At the end of each longitudinal edge. During the injection sequence, the legs 5, 6 facilitate tilting the container platform 4.

As a variant, a weight (not shown) may be provided on the container platform 4 to facilitate tilting the container platform 4 during the injection sequence.

Further, containers 12A, 12B, 12C
A mounting frame 7 is provided on the container platform 4 so as to be detachable. FIG. 1 schematically shows that the containers 12A, 12B, and 12C can be removed and replaced from the container platform 4.
Shown in Also, each container 12A, 12B, 12C
Preferably, it holds a seal 14 with a fluid link 16, an air discharge tube 18, and a handle 25 to facilitate removal and replacement of the containers 12A, 12B, 12C.

The above three containers 12A, 12B, 12
C is a container platform 4 with three lines of symmetry
Are removably attached to three arrangement frames 7 provided at the same position.

It should be noted that the infusion device according to the present invention is suitable for four, five, six or more containers equipped with a suitable rectangular, pentagonal or hexagonal or more polygonal container platform. Also included.

The injection device according to the present invention also includes a container platform (ie, seesaw type) that pivots around a pivot point provided in the center.
One that can be used for only one container may be used.

As a modification of the present embodiment, the pivot arrangement 32 may be installed on the container platform 4 without using the base plate 10. In this way, the platform 4 is free to pivot with respect to the base plate or the ground, which is not part of the injection device.

The container platform 4 of the injection device 2 has a support 30 for supporting the fixed mounting 20 parallel to the container platform 4, a swivel holding arm 22,
A pivot 24 and a fluid introduction assembly 8 are mounted. Further, the fluid introduction assembly 8 includes a distribution unit 19 to which the fluid is supplied from the common fluid introduction portion 28 to the center. The distribution unit 19 provides three equal flows from the center via the fluid link 16 and the fluid link connector 17, and furthermore, the fluid link 16 is connected to each container 12 A, 12 B along the surface of the fixed mounting 20. , 12C.

Further, the holding arm 22 is pivoted in the direction of the arrow 26 via the pivot 24 so that the containers 12A, 1
2B and 12C can be removed and replaced. When the containers 12A, 12B, and 12C are positioned on the placement frame 7, the handles 25 of the containers 12A, 12B, and 12C are locked by the holding arms 22, and the containers 12A, 12B, and 12C are locked.
A, 12B and 12C are fixed to the frame 7.

The holding arms 22 are used for the containers 12A, 12
The holding arm 22 is preferably designed such that the fluid link 16 and the air discharge tube 18 can pass through the holding arm 22 when the handle 25 of B, 12C is fixed.

The arrangement of the injection device 2 shown in FIG.
(1) a container 12A, preferably a fluid,
If 12B is full and container 12C is partially filled (hereinafter referred to as partially full) or empty, (2) container 12A is full and container 12B is empty Or (3) the container 12A is partially full and the containers 12B and 12C are empty and the container 12A is initially filled with fluid. Indicates that the container is

In the above cases (1) to (3), the container 12
A is the container located lowest by the gravity of the fluid held inside. In this case, container 1
2A tilts the container platform 4 and is further facilitated by the legs 4,5 so that the edge of the container platform 4 contacts the contact points 34 of the base plate 10. By this operation, the other containers 12B and 12C are relatively separately transposed at the same time in the vertical direction. Thus, in the above example, the container 12B is positioned lower than the container 12C with respect to the base plate 10 (the container 12A is positioned lower than the container 12B with respect to the base plate 10).

It can be seen from FIG. 1 that the fluid, which is preferably a liquid, is directed to the injection device 2 via the fluid injection assembly 8. The fluid injection assembly 8 directs flow in the direction of arrow 31 to the distribution unit 19 via a common central fluid injection 28. From the distribution unit 19, the fluid is guided through one of the fluid link connectors 17 to one of the fluid rings 16 connected to the containers 12A, 12B, 12C via the seal portion 14.

On the other hand, the containers 12A, 12B, 12
Depending on the relative vertical transposition of C, by gravity, the fluid causes the lowest containers 12A, 12B,
12C (in the present embodiment, container 12A)
Will be injected into.

During the injection sequence, containers 12A, 12A
B, while the fluid is being injected into 12C, the fluid
Container 12A via a fluid link 16 passing through
It is injected into 12B and 12C. Fluid is container 12A,
By being filled with 12B, 12C, air is exhausted from the containers 12A, 12B, 12C and discharged to the atmosphere via the air discharge tube 18. Needless to say, in order to prevent a fluid leak, the air discharge tube 18 must be evacuated at least at a position higher than the highest container.

Each container 12A,
Since the fluid links 16 of 12B and 12C are guided to the liquid level required when the fluid is full, a predetermined amount of fluid is injected into each of the containers 12A, 12B and 12C. As described above, since the capacity of each container 12A, 12B, 12C can be adjusted, the volume of the fluid to be injected can be changed.

Normally, since the air discharge tube 18 penetrates the seal portion 14 and is at the same height as the fluid link 16,
Air can escape, once the container 12A,
When the fluid volume of 12B, 12C reaches a desired amount, the fluid seals the air discharge tube 18.

As described above, since the air discharge tube 18 allows the air to escape above the injection device 2 and exhausts the air, the occurrence of a fluid leak through the air exhaust means is prevented.

The use of another means of insertion (not shown) into the seal 14 allows the operator of the injection device 2 to confirm that one or more containers are full, remove the containers and replace the empty container with an empty container. You can let them know that you need to exchange. Therefore, it is preferable that the seal portion 14 is permanently provided to the injection device 2.

As a modified example, by forming the air discharge tube 18 from a transparent material, it is possible to confirm a fluid that is preferably liquid in the air discharge tube 18 above the seal 14. In this way, the operator can be notified of a container that needs to be replaced with an empty container. Further, the containers 12A, 12B, 12
Clearly, forming C itself from a transparent material can facilitate identification of the full container.

In order to replace the container, the container 12A,
When removing the seal part 14 from 12B, 12C, it is preferable that the injection device 2 is provided with the liquid dripping prevention means. An example of such an anti-dripping seal is disclosed in British Patent Application No. 9616619.3, filed August 8, 1996, Kodak Company.

Next, reference will be made to FIG. 2, which is a plan view of the injection device 2 as seen from the direction of arrow II in FIG. In the above drawings, the containers 12A, 12B, and 12C together with the fluid link 16, the seal portion 14, and the air discharge tube 18
Omitted.

FIG. 2 shows a weight 4A, which is an optional component disposed on the edge or upper surface of the platform 4. The weight 4 </ b> A assists the legs 5, 6 or is an alternative to the legs 5, 6. When the weight 4A is provided as shown in FIG. 2, the leg 6 closest to the arrangement frame 7 is optional.

A leg 5 which is slightly longer than the leg 6 is preferably located at the center of each longitudinal edge of the platform 4. By arranging the legs 5, the inclination of the container platform 4 is promoted to the maximum.

The injection device 2 viewed from the direction of arrow III in FIG.
FIG. 3 which is a side view of FIG. In the figure, the inclination of the container platform 4 is exaggerated, and furthermore the upper part of the injection device 2 and the containers 12A, 12A
B and 12C are omitted.

It can be seen that the container platform 4 is free to pivot about a pivot arrangement 32 provided in the center. The pivot arrangement 32 may be arranged at the center of the back surface 4C of the container platform 4. Also, regardless of the presence or absence of the base plate 10,
Instead of the pivot arrangement 32, a simple spike may be directly attached to the back surface 4C of the container platform 4.

Referring to FIGS. 4 (a), 4 (b) and 4 (c) which are schematic views of the injection device 2 according to FIG. The above schematic diagram shows an injection sequence according to the embodiment of the present invention. 4A to 4C, solid-line hatching indicates a filled container, broken-line hatching indicates a partially filled container, and no hatching indicates an empty container.

With the containers 12A, 12B, 12C removably attached to the container platform 4, the normal unbalance condition promoted by the legs 5, 6 allows one container 12A to be separated from the other two containers 12B, It is positioned lower than 12C. The leg 6 closest to the container 12A further increases the inclination of the container platform 4, and the edge of the container platform 4 opposite the container 12A contacts the base plate 10 at the contact point. This causes the containers 12B and 12C to be separately transposed vertically in relation to each other, and the container 12B is
, But neither container 12B nor container 12C will be lower than container 12A.

Subsequently, reference will be made to FIG. When the fluid, which is preferably a liquid, is injected into the injection device 2 via the fluid introduction assembly 8 when the container 12A is the lowest container, the fluid is preferentially moved in the direction of the solid arrow by gravity. The flow is injected into the container 12A. When the container 12A is full (indicated by solid hatching), excess fluid (assuming the fluid is not depleted) is forced to stagnate, flows along the injection sequence in the direction of the dashed arrow, and becomes the second lowest. The located container 12B is filled until it is partially filled (indicated by dashed hatching).

In a typical filling sequence, the full container 12A is removed and replaced with an empty container. With this replacement, the new heavy container 12B
Is selected, the balance of the container platform 4 is shifted, and the edge of the container platform 4 opposite to the container 12B is contact point 3
At 6, it contacts the base plate 10. Accordingly, the container platform 4 necessarily rotates around the pivot point 32, and shifts the second container 12B to be subsequently filled with the fluid to the lowest position (that is, the position that can be preferentially filled).

By removing the full container 12A shown in FIG. 4A during the injection sequence and replacing it with an empty container, the fluid flows preferentially in the direction of the solid arrow in FIG. 4B, and FIG. At this point, the container 12B is partially filled, and the filling device 2 is further filled. Thus, the container 12B is partially filled (FIG. 4).
(A) is indicated by the dashed line hatching) to the full state (FIG. 4).
(Shown by solid-line hatching in (b)).

When the container 12B is full, the excess fluid (which shall not be consumed) is forcibly stagnated, before the container platform 4 rotates and the leg 6 closest to the container 12B. As a result, the inclination of the platform 4 is promoted, so that the fluid is newly injected into the lowest container 12C.

During a typical injection sequence, container 12B is removed and replaced with an empty container.
This exchange again shifts the balance of the container platform 4 and the weight of the new heaviest partially filled container 12C causes the edge of the container platform 4 opposite the container 12C to contact point 3
At 8, it contacts the base plate 10. Thus, the container platform 4 necessarily rotates around the pivot point 32, and shifts the next container 12C to be filled to the lowest position (that is, the position that can be preferentially filled).

Next, during the injection sequence, by removing the full container 12B of FIG. 4B and replacing it with an empty container, the fluid flows preferentially in the direction of the solid arrow in FIG. At the time of (b), it is injected into the partially filled container 12C and further injected into the injection device 2. In this way, the container 12B changes from a partially filled state (shown by a hatched line in FIG. 4B) to a filled state (shown by a solid line hatched in FIG. 4C).

When the container 12C is full, the excess fluid (assuming the fluid is not consumed) is forcibly stagnated, the container platform 4 is rotated in advance, and the platform 6 is moved by the legs 6 closest to the container 12C. The incline of 4 is facilitated so that the container 12A, which is newly lowest and has been replaced previously with a full container, is free to receive fluid and is empty, is filled.

During the above sequence, the container platform 4 is rotated substantially around the pivot point 32 and the sequence is repeated until the fluid is exhausted or the injection sequence is completed (schematically in the diagram). 4 (a) → FIG. 4 (b) → FIG. 4 (c) → FIG.
(A). . . Like this).

Injecting the fluid into the injection sequence may be continuous or intermittent.

Referring to FIG. 5, the characteristics of the leg 5 capable of adjusting the expansion and contraction will be described. Note that FIG. 5 is similarly applied to the description of the legs 6 and the legs 5 and 6 arranged around the container platform 4.

In a variant, the extension of the leg 5 during operation is slightly longer than the extension of the leg 6. This facilitates the operation of tilting the container platform 4 when removing the full container (and replacing it with a new container).

According to the embodiment described with reference to FIGS.
It can be seen that the injection sequence continues indefinitely.

The arrangement shown in FIGS. 1 to 5 is inconvenient depending on the shape of the space in which the injection device 2 can be installed.
A variant (not shown) in which the containers can be aligned in a row, if necessary, in accordance with the principles of the present invention is to removably mount the container on the biasing means instead of tilting the container platform. is required. When the container is empty, the biasing means relatively displaces the container in the vertical direction.

The foregoing variations of the above embodiment also include containers which are preferably mounted on a plurality of springs or pivot balances.

When using springs, the plurality of springs have different lengths and different strengths so that when all containers are empty, the detachably mounted containers are transposed separately vertically. At least one of them must be retained. In addition, the spring must have adequate flexibility and length to provide adequate mobility to the container. In this way, the partially full container is positioned lower than the empty container in the vertical direction, and the full container is positioned lower than the partially full container in the vertical direction.

If a pivot balance is used, the pivot balance must include a mounting frame for providing a detachably mounted container at one end and a weight at the opposite end. When the container is empty, the weights are sufficient to balance the weight of the container, so the empty container is positioned highest in the vertical direction, while when the container is full or partially full, The full and partially full containers are positioned lowest in the vertical direction because the weight is insufficient to balance the weight of the container.

The above variant preferably includes fluid links that can be individually transposed vertically from each container to a common central fluid inlet and to follow each container.

The central common fluid introduction part may be arranged in a slope form for a plurality of containers, and the relative displacement of each fluid link connection part to the introduction part in the vertical direction along the slope serving as the introduction part. Can be lowered continuously.

[0092] The above variant of the injection device requires a means for regulating the flow of fluid in the container so as to preferentially inject a partially filled container before injecting the fluid into an empty container.

The above-described injection sequence is achieved by discharging the fluid passing through the common central fluid introduction portion by the fluid link. The lowermost open link is connected to the container to which the fluid is preferentially injected. (I.e., each fluid link is vertically displaced separately so as to connect to (i.e., an empty container at the beginning of the infusion sequence, but which will be partially full during the infusion sequence). preferable.

[0092] Due to the weight of the container into which the fluid is injected on the biasing means until the partially or empty container is filled with the fluid, the container into which the fluid is injected at the low or lowest position during the injection sequence is: , Gradually or quickly transposed in the vertical direction (eg forming a biasing means, depending on a spring or pivot balance).

Thereafter, the fluid from the central common fluid inlet stagnates and the fluid is injected via the second fluid link into the empty second container until the second container is partially or completely filled. You. The fluid link of the second container is open and has been displaced vertically higher than the fluid link of the previously filled container and lower than the fluid link of another empty container.

If the second container is full of fluid and the fluid is not depleted, the injection sequence is repeated and fluid from the central common inlet is transferred to another container via a separate fluid link to another container. Is partially or fully filled. The fluid link is vertically higher than the fluid link of the previously filled container and is transposed lower than the fluid link of another container.

If one or more containers are full, the full containers can be removed and replaced with empty containers without interrupting the injection sequence.
It is preferable that the partially filled container is not removed.

If the biasing means is a spring, the container will be filled with fluid during the filling sequence and a partially filled container will be filled, or an empty container will be partially filled or filled, and the spring will be partially or fully filled. Until it is retracted, the spring to which the container is attached is gradually displaced vertically, even in a low configuration, by the elasticity of the flexible spring.

When the tilting means is of a pivot balance, fluid is injected into an empty container to make it partially full or full, and to maintain it at the lowest position of the container platform or the pivot balance, or when it is partially full. When the container was filled with fluid and kept at the lowest position, by injecting the fluid into the container during the filling sequence, the pivot balance to which the container was attached immediately Displaced to the lowest position.

By removing the full container from the injection sequence and replacing it with an empty container, the biasing means reduces the container weight and allows it to return to its initial state. This allows the injection sequence to be continued indefinitely without interruption.

[0099]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS By using the injection apparatus and the injection method according to the present invention described above, the problems of the prior art described in the above-mentioned "Problems to be solved by the invention" are solved as follows.

As explained above, if an operator collects an average of 18 liters of process effluent (overflow) daily from a processor having a maximum capacity of less than 24 liters, at least three standard 10 liter containers are required. .

Using the injection device according to the present invention shown in FIG. 1, three 10-liter containers 12A, 12A
B, 12C are removably attached to the container platform 4 to distinguish them from A, B, C, respectively. As with the prior art illustration described above, the fluid discharge from the processing apparatus used in the embodiment according to the present invention is a constant 18 l / l.
day (equivalent to the amount introduced into the injection device 2 in FIG. 1). When the above-described injection sequence is started, the fluid is first injected into the container A, and then into the container B. The state of fluid injection of the container at the end of the first day is the same as that of the above-mentioned conventional surgery as shown below.

[0102]

[Table 2]

However, on the second day, if the full container A (ie, the heaviest and lowest container) is removed, the container B becomes the heaviest and is subsequently transposed to become the lowest container. Continue to Container B
, And when full, inject fluid into the new lowest container (ie, container C). The injection sequence is as follows.

[0104]

[Table 3]

Thus, after the fifth day, the injection sequence is repeated without reaching the volume limit (ie, without causing overflow).

It will of course be understood that the invention has been described only by way of example and that modifications can be made without departing from the scope of the invention as defined in the claims.

[0107]

According to the filling apparatus and the filling method according to the present invention, the full container, the partially full container and the empty container are vertically displaced, and if the other container is empty due to the weight of the full container. By preferentially positioning the partially-filled container at the lowest position, the partially-filled container can be first filled and filled with fluid, and the container can be automatically filled with fluid.

The present invention can be effectively used for collecting waste liquid, especially photochemical waste liquid. By using the present invention, photochemical waste liquid can be collected directly into a container equipped with an automatic switching system that requires an operator to perform minimum processing. It is only required to change the filling container daily. By removing the container, the fluid is accurately injected and filled,
Extra waste management costs can be reduced (i.e. partially filled containers are fully filled as well as removed containers). On the other hand, the operator need not perform the operation of injecting the fluid.

Since the mechanical properties of the present invention are dependent on the gravitational force that operates the system, it avoids the problems associated with electrical switching systems that may be unreliable and can be manufactured inexpensively. It is possible to sell.
