The present invention relates to an inhibitor solution supplying device for a battery for injecting an electrolyte solution into a battery including a plurality of cells.

When the electrolyte is first injected into the battery when the battery is conventionally charged and the electrolyte is not injected, the electrolyte is not required at all thereafter, i.e., each cell of the dry discharge lead oxide battery has a specified amount of electrolyte. As a device for injecting a battery, a monoblock electrolyte container in which an electrolyte for one storage battery (total cells) is collected and filled into one container is used (Japanese Utility Model Publication No. 35-8021). In the container, since each cell is sequentially injected by visual measurement, there is an unreasonable reason that excessive or insufficient amount of the pouring amount of each cell is caused and the readjustment work is accompanied. In addition, since an electrolyte container is transferred from one cell to another, a considerable amount of effort and time are required for pouring, and there is a drawback in that the electrolyte flows over the upper surface of the battery.

Therefore, in order to eliminate such a fault, as shown in FIG. 22, the body part 2 'having the liquid injection container 3' at the end is connected in the same number of times as the number of cells, and the electrolytic solution for each cell unit in each body part 2 '. (5 ') has been proposed (Japanese Patent Laid-Open No. 60-74343). However, in this electrolyte container, the tip of the electrolyte container has to be cut with scissors or a nipper. Besides. Not only the cut-off portion scatters at the time of cutting by scissors or a nipper, but the electrolyte 5 'accumulated in the removed portion may scatter depending on the scattering.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electrolyte supply device which is not cumbersome and can inject an accurate amount of electrolyte into each cell of a storage battery in a short time, and can reliably inject without using scissors or a nipper.

In order to achieve the above object, the first to sixth inventions of the present application connect the body parts in which the electrolyte solution of each cell unit of the storage battery is injected and sealed several times the same as the number of cells to form an electrolyte solution container, A battery electrolyte supply device in which a cylinder is provided and the spacing between the liquid reservoirs is matched with the spacing of the battery parts so that the liquid container can be freely fitted to the liquid injection part. Each body part is sealed, and this thin film part is made to open, and each body part is opened.

In the second invention of the present application, in order to prevent breakage of the thin film portion due to an impact during transportation of the container, in addition to the configuration of the first invention, a sealing plug for a battery can be useful as a protective stopper for a container.

According to the third invention of the present application, in addition to the configuration of the first invention, the electrolyte solution can be freely fitted into the inner circumference of the liquid container of the electrolyte container so that the electrolyte can be reliably poured without leaking or clogging, and the liquid container can be opened freely. An injection-molding sleeve having a shape protruding upward is formed in the injection portion of the storage battery, and an air groove for supplying air to the electrolyte container is formed on the outer circumferential surface of the sleeve.

In the fourth invention of the present application, in addition to the configuration of the first invention, the electrolyte solution can be freely fitted to the inner circumferential surface of the electrolyte container so that the electrolyte solution can be reliably injected without leaking or clogging, and the liquid container can be opened freely. A liquid injection sleeve having an upwardly protruding shape is formed, and an air groove for supplying air to the electrolyte container is formed on the inner circumferential surface of the liquid container.

In order to improve durability and corrosion resistance of the thin film portion, the invention of FIG. 5 forms a polyester resin layer having heat resistance on both sides of the aluminum sheet as the thin film portion body in addition to the configuration of the first invention. The polyethylene resin layer for thermocompression bonding of the same material as the container is formed on the innermost side of the substrate.

In the sixth invention of the present application, in order to reliably prevent the improvement of the opening performance of the thin film portion and the clogging of the air groove during pouring, the cut portion is formed at the top end of the sleeve in addition to the configuration of the third invention. An air groove is formed at a position circumferentially displaced from the uppermost end, and ribs protruding radially outward are formed on the outer circumferential surface of the sleeve corresponding to the lower end portion of the air groove.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described with reference to an accompanying drawing.

Example 1

In FIG. 1 which shows the electrolyte supply apparatus to which the 1st invention of this application was applied, the electrolyte solution container 1 consists of polyethylene (polyolefin type) synthetic resins, and the body part 2 of six substantially rectangular parallelepipeds connected in succession is shown. Have The body parts 2 are integrally formed with each other, and a cylindrical liquid injection tube 3 is formed integrally with the front end part (the upper end part of FIG. 1) of each body part 2. The inside of the fuselage part 2 is a cavity isolate | separated by each fuselage part 2, and each fuselage part 2 has the electrolyte solution of each cell unit of a dry discharge lead oxide storage battery (it mentions later). (5) is stored. In addition, the electrolyte solution 5 is first injected into the fuselage 2 to be sealed, but part 5a of the electrolyte solution 5 flows into the injection container 3 due to vibration during transportation or the like, and is directly injected by surface tension. It is often preserved in the cylinder 3.

A thin film part (tape row seal part) 6 is provided at the tip of each liquid container 3, and the upper end part of each liquid container 3 is sealed by the said thin film part 6. The thin film part 6 consists of an aluminum sheet layer and a polyethylene-type (polyolefin type) resin layer, and the polyethylene-type resin layer melt | dissolves by heat in the pouring tank 3 of the electrolyte container 1 by heat.

In FIG. 4 showing an example of a dry discharge lead oxide storage battery in which the electrolyte container 1 is used, the dry discharge lead oxide storage battery 10 includes a container 13 and an upper container lid 14. In the container 13, for example, the cell walls 12 are partitioned into six cell chambers 12, and coupling elements (pole plates, separators, etc.) are inserted into each cell chamber 12. As shown in FIG.

In the lid 14 corresponding to each cell chamber 12, as shown in FIG. 2, a concave injection portion 17 is integrally formed with the lid 14. In the bottom portion, a pouring hole 18 communicating with the cell chamber 12 below is formed. In the portion of the pouring hole 18, a cylindrical sleeve (projection portion) 20 extending upward is formed integrally with the lid 14, and the upper edge of the sleeve 20 is cut at an angle and is sharp. It is supposed to be plump. In addition, an air hole 21 is formed in the side wall of the pouring part 17, and the air hole 21 communicates with the cell chamber 12 and the inside of the pouring part 17. A cylindrical projection 25 is also formed in the pouring hole 18 below, and the flow rate (injection speed) is regulated by the passage in the projection 25.

Moreover, the aluminum foil 23 which coated the synthetic resin on the lid 14 side is fixed to the upper surface of the lid 14 before electrolyte injection, and the injection part 17 is sealed by the aluminum foil 23, As a result, the charged electrode plates in the cell chamber 12 are prevented from contacting the air. The above-mentioned price D of the adjacent liquid tanks 3 of FIG. 1 coincides with the interval of the adjacent liquid pouring parts 17 of FIG. 2, and therefore, the entire liquid bottles 3 of FIG. It is possible to fit in each pouring part 17.

Next, the usage method is demonstrated.

In order to start the use of the dry discharge lead oxide battery, it is necessary to inject the electrolyte into the battery, and the electrolyte container 1 shown in FIG. 1 is used. First, the aluminum foil 23 of FIG. 2 is peeled off from the lid 14 to expose the pouring portion 17.

Next, the electrolyte container 1 is turned upside down, and the respective injection barrels 3 are inserted and pushed into the respective injection portions 17, so that the thin film portion 6 is drilled by the sleeve 20 as shown in FIG. The liquid container 3 is covered with the sleeve 20.

Then, in the state as shown in FIG. 4, when the air hole is drilled into the bottom of the body portion 2 of the electrolyte container 1 by a pin or the like, the electrolyte solution 5 is injected into each cell chamber 12 at a predetermined pouring speed. . Air in the cell chamber 12 is discharged from the air hole 21 in FIG.

When the pouring is completed, the container 1 is removed from the pouring portion 17, and a sealing plug (not shown) is fitted to the pouring portion 17 to seal the pouring hole 18. As the sealing plug, for example, a number of plug bodies corresponding to the number of the pouring parts 17 (in this case, six) is integrally connected to each other via the flexible part.

In addition, when the sleeve 20 of the shape which protrudes upward is formed in each liquid injection part 17 of a storage battery like 2nd, the thin film part is made by the sleeve 20 only by inserting the injection liquid container 3. (6) can be opened and opened, and at the same time, the pouring container 3 can be connected to the pouring part 17 and the pouring operation can be performed in that state, which is very practical.

Example 2

5 is an example in which the passage 27 for restricting the flow rate is formed in the pouring container 3. If the pouring speed is too high, the electrolyte solution will not flow from the battery or the predetermined battery performance will not be exhibited, so 0.5 to 2.0 cc / sec is preferable.

Example 3

6 to 9 show an electrolytic solution supply apparatus to which the present application is applied, according to the second invention. The structure of the electrolytic solution container 1 is the same as that of the above-described FIG. 1, and the same parts are assigned the same numbers.

Then, the bottomed cylindrical sealing cap 30 for a battery is fitted to the outer circumference of each pouring container 3. Each sealing stopper 30 is integrally connected by the flexible connection part 31 as shown in FIG.

As the storage battery, a storage battery having the same structure as that shown in FIGS. 4 and 2 is used. In FIG. 8, the same components as those in FIG.

In FIG. 7, the intervals D of the sealing plugs 30 adjacent to each other coincide with the intervals of the pouring parts 17 adjacent to each other in FIG. 8, so that each sealing stopper 30 is simultaneously dispensed in each of FIG. It can fit in the part 17.

Next, the usage method is demonstrated.

When the electrolyte container is stored or transported, the sealing stopper 30 is fitted into the pouring container 3 of the electrolyte container 1 as shown in FIG. 6, so that the thin film portion 6 is not penetrated by an impact or the like.

When the electrolyte is injected into the battery to start the use of the dry discharge lead oxide storage battery, the sealing plug 30 is removed from the electrolyte container 1 and then executed. The actual injection operation is the same as the method described in FIGS. 2 and 3 described above.

When the pouring is completed, the container 1 is removed from the pouring portion 17 and the sealing hole 30 is sealed by fitting the sealing stopper 30 to each pouring portion 17 as shown in FIG.

Example 4

10 to 14 show an electrolyte supply apparatus to which the third invention of the present application is applied, wherein the outer diameter of the injection sleeve 20 is inscribed inside the injection tank 3 of the electrolyte container 1. Size. In practice, however, there is a diameter difference of about 0.2 to 0.5 mm. The inner diameter of the liquid injection sleeve 20 is made small, for example, in order to adjust the injection speed. If the pouring speed is too high, the electrolyte solution will not flow out of the battery or the battery performance of the battery will not be exhibited, so 0.5 to 2.0 cc / sec is preferable.

In order to make the instrument which penetrates the thin film part 6 of the electrolyte container 1 in the upper end surface of the liquid injection sleeve 20, the synchronization 22 of the shape which protruded upwards is formed. On the outer circumferential surface of the liquid injection sleeve 20, four air grooves 19 extending upwardly are formed as shown in Figs. 12 and 13, and during the liquid injection through the air groove 19, Four air grooves 19 are formed, and the air grooves 19 allow air to be introduced into the electrolyte container 1 at the time of pouring.

The structure of the other electrolyte container and the structure of the storage battery are substantially the same as those in the above-described first embodiment, and the same components are assigned the same numbers. The tip end of the pouring bottle 3 has an enlarged diameter as the pouring sleeve introduction part 3a.

The method of use is the same as that of the first embodiment, but as shown in FIG. 11, the pouring container 3 is securely fitted to the sleeve 20 in the pouring solution, and the electrolyte 5 in the container 1 is air in the pouring solution. It is replaced by the air flowing into the vessel 1 in the groove 19 and supplied into the cell chamber 12. Therefore, it is possible to easily supply the electrolyte solution even if air holes are not drilled in the bottom of the electrolyte container 1. In addition, the air in the cell chamber 12 is discharged from the air hole 21.

In FIG. 13 and the like, four air grooves 19 are formed, but only one air groove 19 may be formed.

Example 5

15 to 18 show an electrolyte supply device to which the fourth invention of the present application is applied, and has an air groove 29 formed on the inner circumferential surface of the container 1 of the container 1. As shown in FIG. 16, three air grooves 29 are formed, for example. The upper edge of the sleeve 20 on the battery side of FIG. 17 is cut obliquely and sharply. The outer diameter of the injection liquid sleeve 20 is the size which inscribes inward of the injection container 3 of the electrolyte container 1.

However, there is actually a diameter difference of about 0.2 ~ 0.5mm. The structure of the other containers and the storage battery is the same as in the above-described first embodiment, and the same components are assigned the same numbers.

Also in this structure, the method of use is the same as that of the first embodiment, but as shown in FIG. 18, the pouring container 3 is reliably fitted to the sleeve 20 in the pouring solution, and in the pouring solution, the electrolyte solution in the container 1 ( 5) is replaced by the air flowing into the vessel 1 from the air groove 29 and supplied into the cell chamber 12. Therefore, even if an air hole is not drilled in the bottom of the electrolyte container 1, electrolyte solution can be supplied easily.

In addition, one or two air grooves 29 may be provided.

Example 6

19 is an enlarged longitudinal sectional view of the thin film portion 6 to which the fifth invention of the present application is applied. However, in order to show the positional relationship of each layer clearly, the thickness is exaggeratedly expressed. The thin film portion 6 is formed on both sides of the aluminum sheet body layer 40, for example, a polyester resin layer 41 having a heat resistance of 220 ° C. or higher, and on the innermost side of the container, The ethylene resin layer 42 is formed. The melting temperature of this polyethylene resin layer 42 is 140-200 degreeC.

In the case of thermocompression bonding the thin film portion 6 to the liquid injection tank 3 of the container 1, thermocompression bonding is performed at a temperature within a melting range of polyethylene. Therefore, even if a hole etc. arise in the polyethylene resin layer 42 at the time of thermocompression bonding, since the aluminum sheet main body layer 40 is protected from the exterior by the polyester resin layer 41, it is made of dilute sulfuric acid electrolyte etc. There is no fear of corrosion and puncture.

Moreover, of course, the thin film part 6 of the structure of FIG. 19 is provided in the same electrolyte container as the case of 1st Embodiment mentioned above.

Example 7

20 and 21 show an electrolytic solution supply apparatus according to the sixth invention of the present application, wherein the sleeve 20 on the battery side is cut off at an oblique top edge, whereby the top end 20a is sharp. ), A cutting portion 48 for forming the thin film portion 6 is easily formed at the uppermost end 20a. The air groove 19 is formed on the outer circumferential surface of the sleeve at a position circumferentially away from the top end portion 20a. In addition, ribs 47 protruding radially outwardly are integrally formed on the outer circumferential surface of the sleeve 20 in a portion corresponding to the lower end of the air groove 19 as shown in FIG. . That is, the portion of the air groove 19 passing through the rib 47 is deep.

The method of use is the same as that of Example 1 mentioned above, but when the injection container 3 of the container 1 is fitted to the sleeve 20, the cutting part 48 is provided in the outermost part 20a lightly, The thin film portion 6 can be easily penetrated by simply pushing the container 1. In other words, the breaking strength can be reduced. By providing the cutting portion 48, since the fragments of the cut holes of the perforated thin film portion 6 become circular, it is difficult to penetrate into the air groove 19.

Moreover, when the liquid container 3 is fully fitted to the sleeve 20, even if the fragments of the cut hole of the thin film part 6 which were drilled try to intrude into the air groove 19, the protrusion of the rib 47 will protrude. The debris is biased to one side to prevent the intrusion, and even if the debris intrudes into the air groove 19, the air groove 19 is deep so that the air groove 19 is not blocked.

As described above, in the electrolyte solution supplying device according to the first to sixth inventions of the present application, (A) the thin film portion 6 is formed at the tip of the pouring container 3 of the container 1 and the thin film portion 6 Since the electrolyte solution of the fuselage part 2 is sealed by this, even if it does not use scissors, a nipper, etc., it can open even if it cuts through the thin film part 6 only by protrusion shape, for example, and it becomes easy to inject liquid. .

In other words, tools for cutting such as scissors and nippers are not necessary, and scattering of the electrolyte solution or scattering of the cut portions in the case of cutting with scissors or nippers or the like is also eliminated.

(B) Since the electrolyte solution 5 of each cell unit is injected and sealed in each fuselage | body part 2, an accurate amount of electrolyte solution can be injected into each cell of a storage battery in a short time.

Moreover, according to 2nd-6th invention of this application, there exist also the following advantages, respectively.

That is, in the second invention of the present application, (a) Since the sealing plug 30 for the battery is fitted to the outer circumference of the pouring container 3, there is no need to provide a storage place for the sealing plug for the battery, in particular. It is convenient to store.

(B) Since the sealing cap 30 for the battery is fitted to the outer circumference of the liquid container 3 to protect the thin film portion 6, even if the protective cap for the special container is not provided, it may be subjected to impacts such as during transportation of the container. The damage of the thin film part 6 by this can be prevented.

In the third and fourth inventions of the present application, (a) Since the injection sleeve 20 of the shape which protrudes upward is formed in the injection hole part for every cell, the injection container 3 of the electrolyte container 1 is opened. By fitting the injection sleeve 20 into the injection sleeve from above, the injection cylinder 3 can be broken and opened in the injection sleeve 20 and the injection cylinder 3 can be connected to the injection sleeve 20. In that state, we can start pouring in soon.

(B) Air grooves 19 (or 29) are formed on the outer circumferential surface of the liquid injection sleeve 20 or the inner circumferential surface of the liquid injection cylinder 3, and by the air grooves 19, 29, Since the electrolyte in the electrolyte container 1 is replaced with air, it is not necessary to drill an air hole in the bottom of the electrolyte container 1, and the pouring operation becomes easier.

In the fifth invention of the present application, as the thin film portion 6, heat-resistant polyester resin layers 41 for protecting the aluminum sheet body layer are formed on both sides of the aluminum sheet body layer 40, and the innermost surface of the container is provided. Since the polyethylene resin layer 42 for thermocompression bonding is formed in the case, when the thin film portion 6 is thermocompression-bonded to the pour bottle 3 of the container, for example, a hole or the like in the polyethylene resin layer 42 is used. Even if this occurs, the aluminum sheath main body layer 40 is protected from the outside by the polyester resin layer 41 and is not corroded by a dilute sulfuric acid electrolyte solution or the like, so that holes or the like are not formed. That is, the aluminum sheet main body layer 40 can be effectively protected from corrosion and the like.

In the sixth invention of the present application, (a) Since the cutting portion 48 is formed at the top end 20a of the sleeve 20 so as to easily penetrate the thin film portion 6, only the container 1 is pushed lightly. Also, the thin film portion 6 can be easily penetrated. In other words, the breaking strength can be reduced. In addition, by providing the cutting part 48, since the fragment of the cut hole of the perforated thin film part 6 turns into a circular shape, it becomes difficult to penetrate into the air groove 19. FIG.

(B) The air groove 19 is formed on the outer circumferential surface of the sleeve at a position circumferentially deviated from the uppermost end 20a, and the lower end of the air groove 19 on the outer circumferential surface of the sleeve 20. Since the rib 47 is integrally formed in the portion corresponding to the cross section, the debris of the thin film portion 6 does not enter the air groove 19 when the instrument is first made to penetrate the thin film portion 6. Moreover, when the liquid container 3 is fully fitted to the sleeve 20, the rib 47 protrudes even if, for example, debris of the cut hole of the thin film portion 6 that is opened attempts to enter the air groove 19. The debris is biased to one side to prevent the intrusion, and even if the debris enters the air groove 19, the air groove 19 is not deeply blocked by the deep air groove 19.
