Description

  The present invention relates to a battery can cleaning device for cleaning a battery can formed in a bag shape.

The battery can that forms the outer shell of the battery is formed into a bag shape by pressing. The battery can is cleaned in order to remove oil and dirt adhering to the surface. In cleaning, many battery cans are put together in a barrel container made of perforated plate or wire mesh. Each container is immersed in order and dried with hot air in a drying box (see, for example, Patent Document 1). The barrel container is rotated in each tank and drying box.
Japanese Patent Laid-Open No. 9-111485 (paragraphs 0010-0019, FIG. 1)

    However, since many battery cans are washed in a state where they are put together in a barrel container, they may collide with each other during the washing and may be damaged. In addition, since the battery cans are irregularly accommodated in the barrel container that has been pulled up, there are cases in which cleaning liquid, rust preventive agent, or flush water has accumulated in the battery can formed in a bag shape. In order to minimize the amount of the cleaning liquid, the rust inhibitor, or the washing water brought into the next tank, it is conceivable that the barrel container is rotated and discharged. When the barrel container is rotated, the piles of the battery cans that overlap each other collapse, and the battery cans may be further damaged or deformed by the weight of the liquid accumulated in the battery cans.

  When the outer surface of the battery can is scratched, the strength as a container is lowered. In addition, if the opening of the battery can is scratched or deformed, a problem may occur when the opening is sealed.

  Then, an object of this invention is to provide the battery can washing | cleaning apparatus which can wash | clean a battery can, without making it collide with each other.

  The battery can cleaning device according to the present invention includes a cleaning tank that stores a cleaning liquid that allows a battery can formed in a bag shape having an opening, and a finish cleaning section that sprays the cleaning liquid on the battery can that is immersed in the cleaning tank. And a drying unit that removes the cleaning liquid sprayed by the finish cleaning unit, and a transport mechanism that allows the cleaning tank, the finish cleaning unit, and the drying unit to pass through with the battery cans separated from each other.

  Alternatively, the battery can cleaning device according to the present invention stores a primary cleaning tank that stores a cleaning liquid that hides a battery can formed in a bag shape having an opening, and a primary cleaning tank that stores cleaning liquid supplied to the primary cleaning tank. A secondary cleaning tank that immerses the battery can that has passed through the tank; a regenerator that distills and regenerates the cleaning liquid in the primary cleaning tank; A drying unit that removes the cleaning liquid sprayed by the finishing cleaning unit, and a transport mechanism that allows the primary cleaning tank, the secondary cleaning tank, the finishing cleaning unit, and the drying unit to pass through the battery cans separately. .

  In addition, in order to transport the battery cans separately, the transport device includes a case for storing the battery cans in a state of being separated from each other and an endless chain in which a large number of cases are attached and circulates. Further, in order to facilitate the linkage with the pre-process or the post-process of the battery can cleaning device, the battery can is inserted into and discharged from the case with the opening directed in a direction crossing the direction of gravity. Moreover, in order to simplify an apparatus, the battery can after drying is discharged | emitted from a case with air.

  According to the battery can cleaning device of the present invention, the battery cans are cleaned without colliding with each other because they pass through the cleaning tank, the finish cleaning unit, and the drying unit with the battery cans separated from each other. be able to. Furthermore, since washing and drying are performed individually one by one, individual washing spots are less likely to occur as compared to a case where many barrel containers are washed together. As a result, when all the battery cans in the barrel container are cleaned to a certain degree or more when cleaning them in a barrel container, the cleaning can be completed in a shorter time than the time required for cleaning. Can be shortened.

  Moreover, according to the battery can cleaning device provided with a transport mechanism in which a large number of cases are attached to a circulating endless chain, the battery can can be continuously cleaned. Also, a battery can cleaning device that inserts the battery can into the case with the opening facing in the direction crossing the gravity direction, or a battery that carries the battery can out of the case with the opening facing in the direction crossing the gravity direction According to the can cleaning apparatus, handling can be performed with a simple structure, and it is easy to link with the automation apparatus in the previous process or the subsequent process.

  A battery can cleaning device 1 according to an embodiment of the present invention will be described with reference to FIGS. A battery can cleaning apparatus 1 shown in FIG. 1 includes a primary cleaning tank 2, a secondary cleaning tank 3, a finish cleaning unit 4, a drying unit 5, a transport mechanism 6, an insertion unit 7, and a discharge unit 8. The battery can cleaning apparatus 1 cleans and dries the battery can 51 formed into a box shape having an opening 51a by press molding while it is transported from the insertion section 7 to the discharge section 8.

  In the primary cleaning tank 2 and the secondary cleaning tank 3, the cleaning liquid W that hides the battery can 51 is stored in order to separate and remove the press oil adhering to the press molding and dust adhering during the transfer from the battery can 51. Has been. As shown in FIG. 2, a plurality of shower nozzles 9 are provided above the primary cleaning tank 2. Before the battery can 51 is immersed in the primary cleaning tank 2 by the shower nozzle 9, the cleaning liquid W pumped from the primary cleaning tank 2 is sprayed evenly on the outer surface and the inner surface.

  As shown in FIG. 1, the liquid level 2 a of the primary cleaning tank 2 is set lower than the liquid level 3 a of the secondary cleaning tank 3. The cleaning liquid W in the primary cleaning tank 2 is recovered and distilled by the distillation regenerator R, so that impurities such as press oil and dust mixed in the cleaning liquid W are removed. The distilled and regenerated cleaning liquid W is sent to the finish cleaning unit 4.

  As shown in FIG. 3, immediately before entering the primary cleaning tank 2, the battery can 51 is in a state of being slightly inclined so that the opening 51a is higher than the bag-closed side. By doing in this way, when the battery can 51 is immersed, air is prevented from being caught therein.

  A plurality of nozzles 10 are attached between the secondary cleaning tank 3 and the primary cleaning tank 2, and the cleaning liquid W in the secondary cleaning tank 3 uses a drop to the liquid level 2 a of the primary cleaning tank 2. The battery can 51 that has left the primary cleaning tank 2 is sprinkled. As shown in FIG. 4, the finish cleaning unit 4 has an injection nozzle 11 that sprays the cleaning liquid W that has been regenerated by distillation onto the battery can 51 that has passed through the secondary cleaning tank 3. The sprayed cleaning liquid W is dripped as it is and stored in the secondary cleaning tank 3. As described above, the cleaning liquid W is temporarily stored in the secondary cleaning tank 3 after being used in the finish cleaning unit 4, and further supplied from the secondary cleaning tank 3 to the primary cleaning tank 2. Then, the cleaning liquid W contaminated with press oil or dust is removed from the impurities by the distillation regenerator R and is again sprayed from the spray nozzle 11 of the finish cleaning section 4.

  The drying unit 5 includes an air nozzle that blows dry air onto the battery can 51. The drying unit 5 is disposed next to the secondary cleaning tank 3, and removes the cleaning liquid W adhering to the battery can 51 that has passed through the finishing cleaning unit 4 while the battery can 51 passes.

  The transport mechanism 6 includes a large number of cases 12 and a chain 13 connected endlessly. As shown in FIG. 5, the case 12 has an open end 12 a large enough to allow the battery can 51 to be inserted, and the other part has the cleaning liquid W in the battery can 51 inserted therein. The battery can 51 is opened to such an extent that the battery can 51 is sufficiently removed. The case 12 is attached to the chain 13 at an angle at which the battery can 51 can be inserted and discharged at the insertion portion 7 and the discharge portion 8 in a state where the opening 51a is directed in a direction crossing the direction of gravity. A number of cases 12 are attached to the chain 13 at equal intervals. In addition, in FIG. 1, the case 12 is drawn less than the number actually attached. The case 12 is made of a material that does not damage the battery can 51 and has excellent corrosion resistance against the cleaning liquid W.

  The chain 13 meanders in the vertical direction so that the case 12 with the battery can 51 placed in the insertion portion 7 is sequentially hidden in the primary cleaning tank 2 and the secondary cleaning tank 3 and then passes through the drying section 5. It circulates from the discharge unit 8 to the insertion unit 7 through the primary cleaning tank 2, the secondary cleaning tank 3, and the drying unit 5. A sprocket 14 is disposed at each turn-back position of the chain 13. A servo motor for driving that circulates the chain 13 is attached to one or a plurality of sprockets 14. The chain 13 is controlled so that each case 12 is temporarily stopped at the insertion portion 7 and the discharge portion 8 by a servo motor and a sensor.

  In the section in which the open end 12a of the case 12 faces sideways by the transport mechanism 6, the section in which the open end 12a faces upward in the primary cleaning tank 2 and the secondary cleaning tank 3, the battery can 51 is attached to the case 12. In order to prevent protrusion from the open end 12a, the band 15 is disposed across the open end 12a of the case 12.

  As illustrated in FIG. 5, the insertion unit 7 pushes the battery can 51 on the conveyor 16 into the case 12 and the guide 17 that stops the battery can 51 that has been conveyed from the previous process on the conveyor 16 in front of the case 12. A cylinder 18 is provided. The transport mechanism 6, the cylinder 18 and the conveyor 16 are synchronized with each other. The cylinder 18 pushes the battery can 51 toward the case 12 after the case 12 stops. The conveyor 16 stops before the cylinder 18 pushes out the battery can 51, and starts moving when the cylinder 18 returns to the original position. The battery can 51 may be inserted by a belt with fins that is disposed above the conveyor 16 and scrapes the battery can 51 toward the open end 12a of the case 12.

  As shown in FIG. 6, the discharge unit 8 includes a discharge nozzle 19 provided with a jet port 19 a toward the case 12. On the open end 12a side of the case 12, a conveyor 20 that conveys the battery can 51 discharged from the case 12 to the next step is disposed. The discharge nozzle 19 blows out air with sufficient momentum to discharge the battery can 51 to a position where it can be conveyed by the conveyor 20. The air may be constantly jetted, or may be jetted when the case 12 stops at a position aligned with the conveyor 20 in synchronization with the transport mechanism 6.

  Next, the operation of cleaning and drying the battery can 51 by the battery can cleaning device 1 configured as described above will be described. The battery can cleaning apparatus 1 inserts the battery cans 51 conveyed from the press machine into the case 12 one by one with the cylinder 18 with the opening 51a facing forward as shown in FIG. As the chain 13 is turned back by the first sprocket 14, the battery can 51 inserted into the case 12 is inverted while the opening 51 a faces downward, and descends toward the primary cleaning tank 2. As shown in FIG. 2, the battery can 51 is applied to the inner and outer surfaces of the battery can 51 by the shower nozzle 9 as shown in FIG.

  As shown in FIG. 3, the battery can 51 is immersed in the cleaning liquid W in a slightly inclined state so as to start to sink from the closed side. As the chain 13 is inverted upward by the sprocket 14 disposed in the primary cleaning tank 2, the chain is inverted with the opening 51a facing downward. As the battery can 51 pulled up from the primary cleaning tank 2 moves upward, the inner surface and the outer surface are rinsed with the cleaning liquid W guided from the secondary cleaning tank 3 and flowing out from the nozzle 10. A sprocket 14 disposed above the primary cleaning tank 2 and facing the chain 13 sideways, and a sprocket 14 disposed above the secondary cleaning tank 3 and turning the chain 13 downward toward the secondary cleaning tank 3 In the meantime, the battery can 51 is conveyed in a state where the opening 51a is erected downward. Thereby, the battery can 51 is discharged so that the cleaning liquid W of the primary cleaning tank 2 does not remain inside.

  Similarly to the case where the battery can 51 is submerged in the primary cleaning tank 2, the battery can 51 is submerged in the secondary cleaning tank 3, and the chain 13 is folded back by the sprocket 14 disposed in the secondary cleaning tank 3. The secondary cleaning tank 3 is pulled up. As shown in FIG. 4, the battery can 51 pulled up from the secondary cleaning tank 3 is washed away with the cleaning liquid W after distillation regeneration sprayed from the spray nozzle 11 on the inner and outer surfaces. A sprocket 14 disposed above the secondary cleaning tank 3 and traversing the chain 13 toward the drying unit 5, and a sprocket 14 disposed above the drying unit 5 and descending the chain 13 toward the drying unit 5. In the meantime, the battery can 51 is conveyed again in an upright state with the opening 51a facing downward. Thereby, the cleaning liquid W remaining inside the battery can 51 is discharged.

  The battery can 51 is inverted while the opening portion 51a faces downward as the chain 13 is folded back by the sprocket 14 provided in the drying unit 5. While the battery can 51 passes through the drying unit 5, dry air is blown by an air nozzle to remove the cleaning liquid W remaining on the inner surface and the outer surface. The dry air can be removed by volatilizing (evaporating) the cleaning liquid W more quickly when heated by a heater. As the chain 13 is folded back by the sprocket 14 disposed above the drying unit 5, the battery can 51 that has passed through the drying unit 5 is inverted.

  And as shown in FIG. 6, the battery can 51 is discharged | emitted on the conveyor 20 arrange | positioned toward the next process with the air injected from the discharge nozzle 19. As shown in FIG. The case 12 after the battery can 51 is discharged passes under the drying unit 5, the secondary cleaning tank 3, and the primary cleaning tank 2 and returns to the insertion unit 7.

  As described above, since the battery can cleaning device 1 puts the battery cans 51 into the case 12 one by one and cleans and dries them while being transported, the battery cans 51 can be prevented from colliding with each other and being damaged. . In addition, since the battery can cleaning device 1 is cleaned and dried individually, cleaning spots hardly occur in each battery can 51. Furthermore, since the battery cans 51 are continuously washed one by one, it is easy to link the previous process and the subsequent process. Therefore, this battery can cleaning device 1 is suitable for incorporation in a production line that is operated unattended. Moreover, since the battery can cleaning apparatus 1 includes the distillation regenerator R and circulates and uses the cleaning liquid W, the amount of the cleaning liquid W to be newly replenished can be reduced.

  The battery can cleaning device according to the present invention can be used as a cleaning device that can individually clean a scratched processed product that requires cleaning by replacing it with a case having a suitable shape. .
