  However, since the thing described in the said patent document 1 immerses all the bowls (storage implements) which stored the tableware in the immersion tank, immersion tank itself becomes large and it is necessary to store a lot of washing water here In addition, there is a need to remove soil components from the stored washing water, or to replace them with clean washing water. In addition, there are many components such as a dipping tank itself, a lift mechanism that moves up and down a bowl that contains tableware, and a jet cleaning part that is taken out of the dipping tank and washed with water from the nozzle, which makes the entire cleaning apparatus large and complicated. . Furthermore, it is necessary to immerse the ridge in the immersion tank for a predetermined time, and there is a problem that the time required for the entire cleaning becomes long.

  In addition, the structure described in Patent Document 2 has a complicated structure because the cleaning tub is rotated by the spraying power of the cleaning water sprayed from the nozzle to the cylindrical cleaning tub in which the object is to be cleaned. Noise caused by rotation is large. Furthermore, since the object to be cleaned is put in and out of the cylindrical cleaning rod each time, there are problems such as complicated handling and unsuitable for continuous cleaning.

  An object of the present invention is to solve the above-described conventional problems, and to efficiently clean an object to be cleaned, and to reduce the size of the cleaning device and simplify the configuration.

  In order to solve the above-described conventional problems, the cleaning method of the present invention includes a storage tool for storing objects to be cleaned adjacent to each other, a transport means for transporting the storage tool, and a transport direction of the storage tool. And a plurality of nozzles that spray a plurality of arranged cleaning water at predetermined intervals, and each of the plurality of arranged nozzles sequentially sprays the cleaning water from the upper side of the container to be transported, and the sprayed cleaning water In this case, the water is drained outside the storage tool while storing a predetermined amount of water in the storage tool so that substantially all of the objects to be cleaned are immersed, and the cleaning water sprayed from the nozzle in the stored cleaning water is adjacent to each other. The stored cleaning water within the interval between the objects is removed, and the cleaning water sprayed from the nozzle is made to flow along the front and back surfaces of the object to be cleaned, so that the object to be cleaned is transported to the storage device. Along the direction We are performed sequentially Te.

  According to the tableware cleaning method of the present invention, the object to be cleaned can be efficiently cleaned, and the size and configuration of the cleaning device can be reduced.

  In the first invention, a plurality of storage devices that store the objects to be cleaned apart from each other, a transport unit that transports the storage device, and a predetermined interval along the transport direction of the storage device are arranged. A nozzle for injecting cleaning water, and for each of the plurality of arranged nozzles, the cleaning water is sequentially injected from the upper side of the container to be transported, and substantially all of the plurality of objects to be cleaned are injected with the injected cleaning water. While storing a predetermined amount of water in the storage device so as to be immersed, the water was drained outside the storage device, and the stored cleaning water sprayed from the nozzles stored water within the interval between objects to be cleaned adjacent to each other. The cleaning water is eliminated, and the cleaning water sprayed from the nozzle is caused to flow along the front and back surfaces of the object to be cleaned, so that the cleaning of the object to be cleaned is sequentially performed along the transport direction of the storage tool. Cleaning method One in which the.

In the cleaning method of the present invention, the immersion cleaning action in the storage tool by storing water so that substantially the entire object to be cleaned is immersed in the storage tool that stores the cleaning object, and the cleaning water in the storage tool in order. Intense fluidization of the entire cleaning device by spraying and draining while storing water , and direct injection of cleaning water to the object to be cleaned by sequentially injecting cleaning water from the upper side of the storage device Due to the contact abutment action and the sequentially sprayed cleaning water, the stored cleaning water within the distance between adjacent objects to be cleaned is removed, the replacement action and the front and back surfaces of the cleaned cleaning water sprayed objects. A high-speed fluidizing action along the line can be generated in combination.

  Furthermore, the composite action can be generated a plurality of times at the position of the nozzle for injecting a plurality of cleaning waters arranged at a predetermined interval along the conveying direction of the storage tool. As a result, dirt on the object to be cleaned can be reliably removed and cleaning can be performed efficiently.

  Furthermore, when a separate immersion cleaning tank is provided as in the prior art and the storage tool is sequentially immersed in the cleaning water, dirt components increase in the cleaning water in the immersion cleaning tank and the cleaning action decreases. become. For this reason, it is necessary to periodically replace the cleaning water in the immersion cleaning tank. On the other hand, in the cleaning method of the present invention, clean cleaning water is sprayed from the upper side of the storage tool and drained out of the storage tool together with the dirt component while storing water in the storage tool. Clean water is always stored inside. As a result, dirt on the object to be cleaned can be reliably removed and cleaning can be performed efficiently.

  In addition, an immersion cleaning tank is separately provided for a predetermined time (for example, 10 to 20 minutes) by the immersion cleaning action by storing water so that substantially the entire object to be cleaned is immersed in the storage device for storing the object to be cleaned. The process of immersing the storage device storing the cleaning object is not necessary. Therefore, also from this point, the object to be cleaned can be efficiently cleaned.

  As described above, it is not necessary to provide a separately fixed immersion cleaning tank, that there is no need for a mechanism for putting the storage tool in and out of the immersion cleaning tank, and that it is only necessary to transport the storage tool in the horizontal direction. The entire cleaning apparatus can be reduced in size and the configuration can be simplified.

  A second aspect of the invention is the cleaning method according to the first aspect of the invention, wherein the cleaning water sprayed from the nozzle is drained out of the storage tool as an overflow at the lower side of the water storage and at the level of water stored while storing a predetermined amount of water. It is what.

  Thereby, the cleaning water can be fluidized in multiple directions in the storage device to efficiently clean the object to be cleaned. In addition, relatively heavy components can be discharged from the lower side of the stored water, and light components can be quickly discharged out of the storage device together with overflowing water, so that the stored cleaning water can be kept clean. Furthermore, after washing, the water can be quickly drained from the lower side of the stored water to the outside of the storage tool. Accordingly, sterilization and drying, which are steps after washing, can be performed efficiently, and the complexity of handling the storage tool can be eliminated.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the cleaning tool includes a cleaning step in which the water level for storing the cleaning water sprayed from the nozzle in the storage tool is lowered to expose the object to be cleaned on the stored water level. The cleaning method is characterized in that it is included in the transport direction.

As a result, the direct contact action of the jet cleaning water to the parts to be cleaned exposed above the water storage level is strengthened, and the peeling of dirt components from the objects to be cleaned is promoted, so that the cleaning apparatus as a whole can be cleaned. It can be done more efficiently. Means for lowering the water level to the water, the injection quantity of the washing water from the nozzle can be adjusted easily be to the amount and balance to drain out of the accommodation tool from the lower side of the reservoir.

  A fourth invention is a cleaning method according to any one of the first to third inventions, wherein the object to be cleaned is tableware.

  Thus, dishes, bowls, bowls, spoons, forks, rice scoops, and dishes such as tongs that grab food can be reliably and efficiently washed.

The predetermined angle (θ1) of the nozzles 10 and 11 is set to, for example, approximately 10 degrees with respect to the vertical plane.

  In the cleaning space 7, a plurality of storage tools 14 storing balls 28 along the moving direction of the storage tool 14 are positioned on the conveyor 2. The cleaning space 7 is divided into a rough cleaning zone 7a, intermediate cleaning zones 7b and 7c, and a final cleaning zone 7d from the entrance side of the storage tool 14. Each cleaning zone is provided with at least one tank 8 for storing cleaning water, a pump 9 and nozzles 10 and 11 as one unit. The classification and number of cleaning zones, and the number of tanks 8, pumps 9, and nozzles 10 and 11 disposed in each cleaning zone are merely examples, and the present invention is not limited to this.

  The shape of the nozzles 10 and 11 for injecting the cleaning water shown in FIGS. 3A and 3B has a rectangular opening cross section, and the short side (t1) is along the moving direction of the container 14 and is long. The side (t2) is arranged in a direction substantially orthogonal to the moving direction of the storage tool 14.

  4 (a) and 4 (b) are configuration diagrams of the ladle 28, FIG. 4 (a) is a plan view when the bowl-shaped portion 28a that crawls food is up, and FIG. 4 (b) is a bowl-shaped portion 28a. It is a top view when the handle | pattern part 28b is made into the perpendicular direction. The ladle 28 is mainly composed of a bowl-shaped portion 28a and a handle portion 28b for food, and an elongated hole 28c for hanging the ladle 28 is formed at the end of the handle portion 28b. Further, end surfaces when the front surface 28f of the hook-shaped portion 28a and the handle portion 28b and the back surface 28g are in the vertical direction are shown as 28d and 28e, respectively.

  The structure of the container 14 for the ladle 28 that is the object to be cleaned and the method for housing the ladle 28 will be described with reference to FIGS.

  The storage tool 14 mainly includes a storage portion 15 and a lid portion 23. The storage portion 15 has vertical walls 16a, 16b, 16c, and 16d, and a bottom plate 17 is fixed to the inside surrounded by the vertical walls 16a, 16b, 16c, and 16d.

  Further, as shown in FIGS. 6 and 8, the bottom plate 17 is positioned on the lower side in the height direction of the vertical walls 16a, 16b, 16c, and 16d, and an opening 18 for washing water outflows on the vertical walls 16b and 16d side. , 19 are formed. A handle 20 is rotatably fixed to the vertical wall 16d by a fixing bracket 21. The vertical wall 16c has a hook member 22 for fixing the lid portion 23 so as to be freely opened and closed.

  The lid portion 23 has a frame 24 made of a wire rod on the outside, and a plurality of wire rods 25 fixed to the frame 24. The lid portion 23 and the storage portion 15 are held by a plurality of rotating members 27, and the lid portion 23 is configured to be openable and closable with respect to the storage portion 15.

  Further, a plurality of holding members 26a and 26b made of a wire rod are fixed to protrude from the upper surface of the bottom plate 17. As shown in FIGS. 5 and 7, a ball 28 is inserted between the plurality of holding members 26a, 26b to hold the front surface 28f and the back surface 28g in a vertical posture, and the plurality of balls 28 are adjacent to each other in advance. The mating front surface 28f and back surface 28g are stored apart. Further, the front surface 28f side of the ladle 28 located at the top is stored away from the vertical wall 16c, and the back surface 28g side of the ladle 28 located at the rearmost is stored away from the vertical wall 16a. The bowl-shaped portion 28a and the handle portion 28b of the ladle 28 are aligned in the same direction.

  Further, the front surface 28f and the back surface 28g of the plurality of balls 28 are held in a vertical posture, but the interval between the holding members 26a and 26b is larger than the dimension between the front surface 28f and the back surface 28g. Is on the back surface 28g side, the plurality of balls 28 are inclined at a predetermined angle with the front surface 28f facing up. Thereby, the postures of the plurality of balls 28 can be stabilized. In addition, although the lower end surface 28e of the hook-shaped portion 28a is in contact with the bottom plate 17, the lower end surface 28e of the handle portion 28b is in contact with a holding member provided on the bottom plate 17, so that a plurality of The longitudinal direction of the ladle 28 is held substantially horizontal (not shown).

  The space between the upper surface of the bottom plate 17 and the wire 25 of the lid portion 23 is set to be larger by a predetermined dimension than between the upper and lower end surfaces 28d of the ladle 28. After the plurality of balls 28 are stored in the storage portion 15 on the bottom plate 17, the lid portion 23 is rotated and fixed to the storage portion 15 by the hook member 22.

  The ladle 28 is stored so that the end side of the handle portion 28b in the longitudinal direction of the ladle 28 and the hook-like portion 28a are located on the side of the openings 18 and 19, respectively. Furthermore, the space | interval of the vertical walls 16b and 16d is made longer than the dimension between the both ends of the longitudinal direction of the ladle 28, and it accommodates and it accommodates.

The storage tool 14 is moved in the cleaning space 7 so that the longitudinal direction of the stored ball 28 is substantially orthogonal to the moving direction of the storage tool 14 and the front surface 28f of the ball 28 is at the head. Further, since the short sides (t1) of the nozzles 10 and 11 are arranged along the moving direction of the storage tool 14, cleaning water having a narrower width is sequentially ejected along the overlapping direction of the ladle 28.

  Next, the state at the time of washing | cleaning of the ball | bowl 28 is demonstrated based on FIGS. In the figure, W indicates the flow of the injected cleaning water, and indicates the flow of the cleaning water injected into the storage device 14 and the outflow path to the outside of the storage device 14 by solid arrows and Fa and Fb.

  10 (a), 10 (b), and 11 show that the cleaning water from the nozzles 10 and 11 reaches the front part in the transport direction of the storage unit 15 by the movement of the storage device 14, and the cleaning water is poured into the storage unit 15. The cleaning state when spraying is shown.

  Washing water (w) having a predetermined spray speed from the nozzles 10 and 11 hits the surface 28 f side of the ladle 28 positioned at the head and the bottom plate 17. The washing water sprayed into the storage unit 15 is stored in the storage unit 15 and flows as indicated by the solid line arrows shown in FIGS. 10B and 11, and the vertical walls 16 a, 16 b, 16 c of the storage unit 15. It flows out as overflow (Fa) from the upper end of 16d.

  Further, as shown in FIG. 11, the water is stored in the storage unit 15 and flows downward from the openings 18 and 19.

  As shown in FIG. 10B, the washing water flows between the vertical wall 16a and the surface 28f of the ladle 28 and flows downward from the openings 18 and 19 (Fb). At this time, the dirt on the surface 28f of the ladle 28 is removed, and the removed dirt component is discharged from the openings 18 and 19 by the flowing washing water.

  In this state, the dirt on the front surface 28f of the ladle 28 located at the head is washed with flowing washing water. The back surface 28g of the ladle 28 located at the front and each of the ladle 28 located after the second are stored in the storage portion. 15 is immersed in the cleaning water stored in the water.

  In the state immersed in the stored washing water, the dirt adhering to the ladle 28 absorbs moisture and softens, creating a situation in which it easily peels off from the surface, and adheres to the ladle 28 by the washing water flowing in the storage portion 15. Some dirt can be removed and removed.

The amount of washing water from the nozzles 10 and 11 is set to flow out as overflow (Fa) from the upper ends of the vertical walls 16a, 16b, 16c and 16d at the same time as it flows downward from the openings 18 and 19. When cleaning water is sprayed from the nozzles 10 and 11 into the storage unit 15, the water is always stored in the storage unit 15. This sets the areas of the openings 18 and 19 so as to flow out as overflow (Fa) from the upper ends of the vertical walls 16a, 16b, 16c and 16d with respect to the amount of cleaning water sprayed from the nozzles 10 and 11 into the storage unit 15. do it.

  12 (a) and 12 (b) show the position after the container 14 is moved by the conveyor 2 from the state of FIG. 10 and the cleaning water hits the end portions 28d and 28e of the ladle 28 positioned at the head, and then the head is positioned at the head. A state is shown in which cleaning water enters a gap between the end portions 28d and 28e of the ladle 28 and the end portions 28d and 28e of the second ball 28 adjacent thereto.

  The cleaning water flows at high speed along the back surface 28g of the ball 28 and the front surface 28f of the second ball 28 where the cleaning water is located at the head in the separated interval, and the dirt is reliably removed for cleaning. In addition, the flow of the stored water and the washing water in the storage unit 15 at this time is the same as the state shown in FIG. Thereafter, this operation is sequentially repeated as the storage tool 14 moves.

  FIGS. 13A and 13B show a cleaning state when the cleaning water from the nozzles 10 and 11 is moved to the position on the back surface 28 g side of the ladle 28 located at the end by the movement of the storage tool 14. . The washing water of the nozzles 10 and 11 flows in contact with the back surface 28g of the ladle 28 located at the tail, removes dirt, and is washed. At this time, the flow of the stored water and the washing water in the storage unit 15 is the same as the state shown in FIG.

  As described above, the cleaning operation shown in FIGS. 10 to 13 is repeated for each of the plurality of arranged nozzles 10 and 11 to complete the cleaning of the ladle 28 stored together with the storage tool 14. The ladle 28 that has been cleaned is stored in the storage tool 14 by, for example, drying and sterilizing in the next step.

  Although not shown, the storage tool 14 is moved back and forth from one direction by the driving means to clean the balls 28, or the storage tool 14 is fixed and the driving means is used to move the nozzles 10 and 11 back and forth. By cleaning the ladle 28, it is possible to reduce the size of the cleaning device and to save space.

FIG. 14 shows a configuration in which the bottom plate 17 is formed with an opening 19 for washing water outflow only on the vertical wall 16b side. As a result, the wash water stored in the storage unit 15 flows out as overflow (Fa) from the upper ends of the vertical walls 16a, 16b, 16c, and 16d of the storage unit 15, and further downward from the opening 19 along the longitudinal direction of the ladle 28. (Fb). In the configuration shown in FIG. 14, the gas flows toward the bowl-shaped portion 28 a along the longitudinal direction of the plurality of balls 28, and flows downward from the opening 19.

  When a plurality of objects to be cleaned are used as the ladle 28, the bowl-shaped portion 28a for receiving food is stored in the storage portion 15 with the opening 19 side. Accordingly, the bowl-shaped portion 28a to which more dirt is attached is located on the opening 19 side, and the removed dirt quickly flows out from the opening 19 together with the washing water stored in water, so that the entire washing water stored in the storage portion 15 is discharged. As a result, the diffusion of the dirt component into the water is reduced, and the cleanliness of the washing water stored in the storage unit 15 can be further increased.

  FIG. 15 shows a configuration in which the bottom plate 17 in the configuration of FIG. 14 is inclined so that the bowl-shaped portion 28a side of the ladle 28 is sequentially inclined downward. Thereby, the washing water stored in the storage unit 15 can be quickly drained after washing, and the water can be removed more efficiently in the next process such as drying and sterilization.

  In the embodiment, the object to be cleaned has been described as the ladle 28, but a plurality of types of tableware such as ladle, rice paddle, and spoon can be stored in the storage tool and simultaneously cleaned. What is necessary is just to comprise this, and the shape and arrangement | positioning of holding member 26a, 26b match | combine with multiple types of tableware. In addition, although the to-be-cleaned object was set as tableware, it is not limited to this, It can apply to other various to-be-cleaned objects.

  As described above, in the cleaning method of the present invention, the immersion cleaning action in the storage tool by storing water so that substantially the entire target object is immersed in the storage tool that stores the target object, The washing water is sprayed in sequence and drained while storing water, and the washing water is intensively fluidized throughout the storage tool, and the cleaning water is jetted from the upper side of the storage tool to the object to be cleaned. The direct contact action of the cleaning water itself and the cleaning water sprayed sequentially eliminates the stored cleaning water within the interval between the cleaning objects adjacent to each other, the replacement action and the cleaning target sprayed water A high-speed fluidizing action along the front and back surfaces of the film can be produced in combination.

  Further, the combined action can be generated a plurality of times at the position of the nozzle for injecting a plurality of cleaning waters arranged at predetermined intervals along the conveying direction of the storage tool. As a result, dirt on the object to be cleaned can be reliably removed and cleaning can be performed efficiently.

  Furthermore, when a separate immersion cleaning tank is provided as in the prior art and the storage tool is sequentially immersed in the cleaning water, dirt components increase in the cleaning water in the immersion cleaning tank and the cleaning action decreases. become. For this reason, it is necessary to periodically replace the cleaning water in the immersion cleaning tank. On the other hand, in the cleaning method of the present invention, clean cleaning water is sprayed from the upper side of the storage tool and drained out of the storage tool together with the dirt component while storing water in the storage tool. Clean water is always stored inside. As a result, dirt on the object to be cleaned can be reliably removed and cleaning can be performed efficiently.

  In addition, a separate immersion cleaning tank is provided for a predetermined time (for example, about 10 minutes) by the immersion cleaning action by storing water so that substantially the entire object to be cleaned is immersed in the storage device for storing the object to be cleaned. The process of immersing the storage device storing the object becomes unnecessary. Therefore, also from this point, the object to be cleaned can be efficiently cleaned.

  As described above, it is not necessary to provide a separately fixed immersion cleaning tank, that there is no need for a mechanism for putting the storage tool in and out of the immersion cleaning tank, and that it is only necessary to transport the storage tool in the horizontal direction. The entire cleaning apparatus can be reduced in size and the configuration can be simplified.

Further, while storing a predetermined amount of the washing water sprayed from the nozzle, the water is drained out of the storage tool as overflow at the lower side of the water storage and at the water level to be stored. This makes it possible to efficiently wash the object to be cleaned by fluidizing the wash water in multiple directions in the storage device. Further, it is possible to keep the contamination of heavier components from the lower side of the reservoir, also to discharge the dirt lighter components out quickly storing tool with flooding, always clean wash water you savings water. Furthermore, after washing, the water can be quickly drained from the lower side of the stored water to the outside of the storage tool. Accordingly, sterilization and drying, which are steps after washing, can be performed efficiently, and the complexity of handling the storage tool can be eliminated.

In addition, the water level of the stored water is reduced by lowering the water level in which the cleaning water sprayed from the nozzle is stored in the storage tool and exposing the object to be cleaned on the stored water level in the transport direction of the storage tool. Strengthen the direct contact action of the spray cleaning water to the part to be cleaned exposed above, and promote the peeling of dirt components from the object to be cleaned, so that the cleaning apparatus as a whole can be cleaned more efficiently. be able to. The cleaning process in which the water level stored in the storage device is lowered is performed, for example, in either the intermediate cleaning zone 7c or the finishing cleaning zone 7d shown in FIG. The stored water level is such that the water level is lowered to such an extent that half or two thirds of the object to be cleaned is exposed above the stored water level.

  The means for lowering the stored water level can be easily adjusted by balancing the amount of washing water sprayed from the nozzle with the amount of water discharged from the lower side of the stored water to the outside of the storage device. This decreases the injection amount of the cleaning water from the nozzles 10 and 11 or decreases the opening area of the nozzles 10 and 11 to decrease the injection amount of the cleaning water and increase the injection speed. When the spraying speed is further increased, the direct contact action of the spray cleaning water to the object to be cleaned can be strengthened, and the peeling of the dirt component from the object to be cleaned can be further promoted.

  The present invention is not limited to tableware, and can also be applied to cleaning objects to be cleaned such as machined parts.
