Description

  The present invention relates to a tableware cleaning method and a tableware cleaning apparatus in a situation where a relatively large amount of tableware to be cleaned such as dishes, bowls, trays, etc. is used, particularly in school, hospital, etc.

  Conventionally, with regard to a tableware cleaning device that is an object to be cleaned, the tableware and the storage device (tableware bowl) are separated and placed on a conveyor for cleaning, or the tableware is stored in the storage device and cleaned in the cleaning device. There is something to do. In recent years, in order to save labor, facilitate handling, and reduce the size of the cleaning device and tableware storage device, products that have been cleaned in the cleaning device while storing the tableware in the storage device have been developed. It has been known.

  As described in Japanese Patent Application Laid-Open No. H10-228561, there is a type in which tableware is stored by giving a certain interval between dishes, and washing water is supplied at a certain interval provided between the dishes to wash the tableware. In order to provide a fixed interval between a plurality of tableware, a plurality of bent metal bars for supporting the vicinity of the central portion of the tableware are provided in the longitudinal direction of the rectangular tableware storage basket.

  Moreover, as described in Patent Document 2, a tableware container capable of freely expanding and reducing the interval between adjacent tableware can be separated, and the interval between adjacent tableware can be separated during cleaning, while being conveyed. When it is desired to have a small volume, such as when storing or storing, there is a tableware container that can narrow the interval between adjacent tableware.

  In the said patent document 2, in order to expand and contract the space | interval of adjacent tableware freely, it is comprised as follows. A plurality of U-shaped frames that are juxtaposed to each other to form a tableware storage space for storing a plurality of tableware, and are connected to each side of the U-shaped frame so that adjacent U-shaped frames can be separated and approached. A pair of link members to be connected, a receiving frame extending between the pair of link members, and a pair of projections provided at the upper end of the U-shaped frame and projecting toward the tableware storage space, In a state in which the shape frame approaches, the pitch between the protrusions is set to be substantially the same as the pitch between the outer edges of the plurality of tableware to be stored, and the outer surface of the tableware stored in the tableware storage space is adjacent to the receptacle By engaging the edge of the plate, the protrusion engages with the outer edge of the tableware, and the edge of the tableware engages with the side of the main body of the receiving plate located in front of the tableware. When they are separated from each other, Accommodating space accommodating ware are spaced apart from each other, when the U-shaped frame to each other is brought close are those dishes contained in tableware housing space was made to approach each other.

  Moreover, as described in Patent Document 3, a plurality of support bars arranged along the stacking direction of the tableware around the tableware storage unit, and a plurality of each of these support bars to hold the peripheral edge of the tableware. A holding member having a locking portion that is movably mounted one by one is provided, the inner surfaces of a plurality of tableware corresponding to the number of holding members are directed upward, and a holding member is interposed between each tableware There is a tableware bowl that is configured to allow room for tableware to move together with the holding member by a predetermined distance according to the shape and size of the tableware above the tableware at the top when stored in the tableware storage unit in a state. .

In Patent Document 3, a plurality of tableware are stored in a tableware storage section of the tableware table with a holding member interposed between the tableware, and the inner surface of the tableware is directed in the traveling direction. By moving through the cleaning device equipped with the cleaning water jet nozzle in a posture and sequentially applying cleaning water from the top tableware, the tableware is moved forward in the direction of movement of the tableware together with the holding member by the energy of the cleaning water. This is a tableware cleaning method in which cleaning is performed sequentially with cleaning water while moving and creating an interval necessary for cleaning between adjacent tableware. The thing described in the said patent document 3 has the characteristics which can make a tableware container small and lightweight also at the time of washing | cleaning other than the time of washing | cleaning compared with what was described in patent document 2. FIG.
JP-A-8-72872 Japanese Patent Laid-Open No. 2000-201879 JP-A-10-137172

  However, what was described in the said patent document 1 is set so that the tableware which is a to-be-cleaned object may mutually be located at predetermined intervals. Therefore, the volume occupied by the container becomes larger than when the tableware is simply transported in a stacked state, and a longer space is required in the cleaning device to provide a fixed interval between the plurality of tableware. There is a limit to downsizing. Furthermore, a relatively large space is required in the process of transporting the container containing the tableware, and it is necessary to set the tableware one by one in the tableware bowl, which is problematic in terms of labor saving. In addition, since the tableware is fixed in the vertical direction, and cleaning is performed with a certain interval between the tableware in advance, the wash water easily passes without contacting the entire surface of the tableware and the back surface, and the cleaning effect is not sufficiently exhibited. is there.

  Moreover, although what was described in the said patent document 2 can miniaturize a container except at the time of washing | cleaning, it is the several tableware which is a to-be-washed object similarly to what was described in patent document 1 at the time of washing | cleaning. Since a certain interval is provided between them, a longer space is required in the cleaning device, and there is a limit to downsizing the cleaning device. Further, it takes time and labor to expand and contract the tableware container, and the configuration becomes complicated, resulting in an increase in weight and cost. In addition, since the tableware is fixed in the vertical direction and a predetermined interval is provided between the tableware, there is a problem that the cleaning water easily passes without contacting the entire surface of the tableware and the back surface, and the cleaning effect is not sufficiently exhibited. . Furthermore, since it is necessary to support each of the plurality of tableware, the pair of protrusions provided at the upper end of the U-shaped frame of the tableware container are arranged so that the protrusions It is necessary to set the pitch substantially equal to the pitch between the outer edges of the plurality of tableware that should accommodate the pitch. However, solids such as leftovers and meat pieces tend to remain on the surface of the tableware after eating, and the pitch between the outer edges of the tableware tends to vary depending on the presence or absence of these. If left outside the center, the stacked tableware will tilt. Therefore, the pitch between the outer edges of the plurality of tableware does not match the pitch between the projections, and there is a possibility that the tableware cannot be stored in the tableware container.

  Furthermore, especially in the case of tableware (porcelain tableware) produced by the baking method, there is a large variation in the height and radial outer edge size of each tableware, and the pitch and protrusions between the outer edges of the plurality of tableware due to the accumulated size variation of the plurality of tableware. There is a risk that it cannot be stored in the tableware container because the pitch does not match. Moreover, depending on the tableware used for eating, the table | surface where the pitch of the outer edges of tableware is small and close is included. In this case, it is difficult to form protrusions for holding each tableware, and the strength is remarkably lowered and easily damaged. Furthermore, the tableware stored in the tableware container must be limited or sorted, and is not versatile. Moreover, since the configuration of the tableware container is complicated, there is a problem that it is difficult for the washing water to hit the tableware sufficiently and it takes time to clean the tableware container itself together with the tableware. In addition, since the tableware is fixed in the vertical direction, and cleaning is performed with a certain interval between the tableware in advance, the wash water easily passes without contacting the entire surface of the tableware and the back surface, and the cleaning effect is not sufficiently exhibited. is there.

  Moreover, since what was described in above-mentioned patent document 3 needs to support each of the several tableware which is a to-be-cleaned object, the several support rod arrange | positioned along the stacking direction of tableware, and tableware In order to hold the peripheral edge, a holding member having a locking portion movably mounted on each of these support rods is provided. However, like what was described in Patent Document 2, solids such as leftovers and pieces of meat are likely to remain on the surface of the tableware after eating, and when these tableware are stacked, the pitch between the outer edges of a plurality of tableware And the pitch of the holding members do not match and there is a possibility that they cannot be stored in the tableware container. In particular, in the case of tableware by the baking method, the height and radial outer edge size variation of each tableware is large, and due to the cumulative size variation of the plurality of tableware, the pitch between the outer edges of the plurality of tableware and the pitch between the holding members. There is a risk that it will not fit in the tableware.

  Moreover, depending on the tableware used for eating, the table | surface where the pitch of the outer edges of tableware is small and close is included. In this case, it is difficult to form a holding member for holding each tableware, and the strength is remarkably lowered and easily damaged. Furthermore, the tableware stored in the tableware container must be limited or sorted, and is not versatile. In addition, there is a possibility that the holding member having the locking portion cannot be freely moved with respect to the support bar due to the presence of foreign matter, etc., thereby causing the problem that the tableware cannot be separated and the cleaning performance is adversely affected. Furthermore, there is a problem that the configuration is complicated and the cost is increased. Further, since the tableware is fixed in the vertical direction, the posture of the tableware does not change, so that the cleaning water easily passes without contacting the entire surface of the tableware and the back surface, and the cleaning effect is not sufficiently exhibited.

  The present invention solves the above-mentioned conventional problems, and aims to reliably and efficiently remove stains on tableware stored in a storage device in a compact manner without requiring individual support of a plurality of tableware. is there.

In order to solve the above-mentioned conventional problems, the tableware cleaning method of the present invention supports the peripheral ends of a plurality of tableware in which the front side and the back side are overlapped in the horizontal direction by a plurality of supports along the overlapping direction. The position regulating member regulates the position of the front surface side of the tableware located at the front and the back side of the tableware located at the end of the plurality of tableware, and the movement and posture change of the plurality of tableware along the stacking direction. , A storage device that moves the storage device in the stacking direction, and a plurality of positions in the transport direction of the storage device that is moved by the transport device. A plurality of cleaning zones having nozzles for spraying cleaning water on the peripheral edge of the tableware stored in the storage device, and the adjacent tableware is brought into contact with each other for each cleaning zone by movement of the storage device by the transport means. In the vertical plane The peripheral edge portion of tableware housed in the storage equipment at a predetermined angle inclined posture, and sequentially injected in a direction overlapping the washing water from the nozzle, the washing water injected from the nozzle of the washing zone of said each contact The adjacent dishes are separated and separated, and a plurality of dishes are sequentially washed by the flow of the wash water flowing into the separated intervals, and the washing water flow trajectory within the separated intervals in the plurality of wash zones. Has a different cleaning zone from the others.

Further, the tableware cleaning apparatus of the present invention supports the peripheral ends of a plurality of tableware in which the front side and the back side are overlapped in the horizontal direction by a plurality of supports along the overlapping direction, and the inside of the plurality of tablewares The position restricting member regulates the position of the front side of the tableware located at the front and the back side of the tableware located at the end so that movement and change of posture along the stacking direction can be freely performed within a predetermined range. The storage tool stored as described above, the transport tool for moving the storage tool in the stacking direction of a plurality of tableware, and the storage tool stored in a plurality of positions in the transport direction of the storage tool moved by the transport means. The cleaning water is sprayed on the peripheral edge of the tableware in a direction intersecting with each other, and includes a plurality of cleaning zones having a plurality of nozzles arranged in a direction perpendicular to the stacking direction of the tableware. Per cleaning zone The peripheral edge portion of tableware housed in the storage equipment at a predetermined angle inclined position with respect to the vertical plane by contacting the tableware adjacent to each other, are sequentially injected in a direction overlapping the washing water from the nozzle, the cleaning zone of the respective The cleaning water sprayed from the nozzles of the nozzles separates and separates the adjacent tableware, and sequentially cleans the plurality of dishes by the flow of the cleaning water that flows into the spaced apart space, and The position of the intersection of the cleaning water from the plurality of nozzles is changed, and the flow path of the cleaning water within the spaced intervals has a different cleaning zone.

  According to the tableware cleaning method and the tableware cleaning apparatus of the present invention, it is possible to reliably and efficiently remove the stains of the tableware stored in the storage device in a compact manner without the need for individual support of a plurality of tableware.

1st invention supports the peripheral edge part of the some tableware which piled up the surface side and the back surface side in the horizontal direction with a some support body along a pile direction, and is located in the head among the said tableware The position regulating member regulates the position of the tableware on the front side and the backside of the tableware, and stores a plurality of tableware so that movement and change in posture along the stacking direction can be freely performed within a predetermined range. Storage means, transport means for moving the storage tool in the stacking direction of a plurality of tableware, and peripheral edges of tableware stored in the storage tool at a plurality of positions in the transport direction of the storage tool moved by the transport means A plurality of cleaning zones each having a nozzle for injecting cleaning water, and the tableware adjacent to each other is brought into contact with each other for each cleaning zone by the movement of the storage device by the transport means, and is inclined at a predetermined angle with respect to the vertical plane. Store in storage The peripheral edge portion of the dishes, and sequentially injected in a direction overlapping the washing water from the nozzle, the washing water injected from the nozzle of the washing zone of said each is spaced away dishes adjacent contact with one another, spaced intervals A plurality of dishes are sequentially washed by the flow of the wash water that has flowed into the plurality of wash zones, and the plurality of wash zones have a wash zone in which the flow path of the wash water within the spaced intervals is different from the others. This is a tableware washing method.

Instead of supporting and restraining the peripheral edge of each tableware as in the conventional example, it can be stored in a predetermined range with freedom of movement and posture change in the overlapping direction, and sequentially injected along the overlapping direction to this peripheral edge. To do. As a result, the individual dishes move and swing immediately following the flow of the washing water, and the adjacent dishes are separated while sequentially repeating the contact state and the non-contact state. Thereby reliably removed dirt flows through the interval in which the wash water is separated, that Ki out to hold the form of spaced-apart intervals.

A handle 24 is provided on the frame 17, and the handle 24 is configured to be rotatable by a rotating member 25.

  As shown in FIGS. 5 and 6, the dishes 37 that are unwashed dishes after eating are stacked in a vertical direction (longitudinal direction) by a predetermined number (for example, 20 to 40) with the surface 37 a of the dishes 37 facing up. With this as a unit, the holder 26 of the storage tool 14 in the vertical posture is stored in the storage unit 15 in an open state. The yarn bottom 37d of the back surface 37b of the lowermost plate 37 is placed on the base plate 16, and is pushed in and stored until the peripheral end portion 37c of the plate 37 contacts the supports 22 and 23. Thereafter, the holding portion 26 is turned to a closed state. At this time, the peripheral end portion 37c of the dish 37 is in contact with or close to the supports 33 and 34. As a result, a predetermined number of plates 37 stacked in the vertical direction are supported by the support bodies 22, 23, 33, 34 at a plurality of locations on the peripheral end portion 37 c.

  Further, the total length (L1) of the surface 37a side of the plate 37 positioned at the top (top) of the stacked plates 37 and the back surface 37b side (including the yarn bottom 37d) of the plate 37 positioned at the end (bottom). On the other hand, the plate 37 stacked on the storage tool 14 is stored so as to have a predetermined space (L2) between the surface 37a of the plate 37 positioned at the top (top) and the inner surfaces of the frames 17 and 28. Therefore, the total length (L3) of the inner surfaces of the base plates 16, 27 and the inner surfaces of the frames 17, 28 of the storage tool 14 is (L1) plus (L2). The predetermined space (L2) is set to 10 to 20 millimeters, for example. (S1) indicates the interval between the peripheral end portions 37c of the plates 37 adjacent to each other.

  The plates 37 are stacked in the vertical direction and stored as a unit in the storage device 14 in the vertical orientation, but the storage device 14 is placed in the horizontal (lateral) orientation with the storage portion 15 facing down. The stacked plates 37 can also be stored.

  After the plurality of dishes 37 are stored in the storage device 14, the storage device 14 is placed in a horizontal (lateral) position with the storage portion 15 facing down and is loaded onto the conveyor 2 in the cleaning space 7. FIG. 7 shows the posture state of the plurality of dishes 37 when the storage tool 14 is changed from the vertical direction to the horizontal direction.

  Further, when the storage device 14 is set in the horizontal direction with the storage portion 15 facing down, the lower part on the surface 37a side of the top plate 37 is in contact with the frame 17 (position restricting member) and positioned at the end. A part on the back surface 37b side of the plate 37 is in contact with the base plate 27 (position regulating member), and the positions of both ends are regulated. In a predetermined range corresponding to a predetermined space (L2) between the front surface 37a of the plate 37 and the inner surfaces of the frames 17 and 28 when the storage device 14 is stored in the vertical direction and the plurality of plates 37 are stored. A peripheral end portion 37c of the plate 37 is supported so as to be freely slidable on the support bodies 22, 23, 33, and 34 along the overlapping direction.

  Further, unlike the above-described prior art, each of the dishes 37 is not supported and fixed by the support member, and the peripheral end portions 37c of the plurality of dishes 37 freely slide the support bodies 22, 23, 33, and 34 in the overlapping direction. A base which is a position restricting member and supports only the peripheral end portion 37c of the entire plurality of dishes 37 and the front surface 37a side of the top dish 37 and the back surface 37b side of the last dish 37. The position is regulated by being supported by the plates 16 and 27 and the frames 17 and 28. Thus, within a predetermined range corresponding to the predetermined space (L2), a plurality of dishes 37 in which the front surface 37a side and the back surface 37b side are overlapped in the horizontal direction are moved along the overlap direction, and the vertical direction (longitudinal direction) and the horizontal direction. (Horizontal direction) posture change is stored so as to be freely within a predetermined range.

  When the storage device 14 is placed in the horizontal direction with the storage unit 15 facing down, the center of gravity of the dish 37 is positioned on the back surface 37b side of the dish 37, so that the plurality of dishes 37 are rotated around the back surface 37b side of the dish 37. The end 37c slides on the supports 22, 23, 33, and 34, and the plurality of dishes 37 are in contact with each other, and are inclined at a predetermined angle (θ3) in the same direction so as to overlap. . In addition, the inclination angle of the dish 37 is different between the dish 37 positioned at the head and the dish 37 positioned at the tail, and the dish 37 positioned at the tail is set to have the maximum tilt angle (θ3) of the dish 37 positioned at the head. The inclination angle gradually becomes smaller in the lateral direction.

  Further, the lower peripheral end portion 37c of the plurality of inclined dishes 37 is in contact with the support bodies 22 and 23, and the inclination angle (θ3) of the dish 37 positioned at the top is maximized, and the dish 37 positioned at the rearmost position. Since the angle of inclination gradually decreases in the lateral direction, the height of the peripheral end portion 37c on the upper side of the plurality of dishes 37 starts from the peripheral end part 37c of the dish 37 located at the rearmost position. It is in the state which becomes low gradually toward the peripheral edge part 37c of the plate | plate 37 located in this. In this state, the upper peripheral end portions 37 c of the plurality of dishes 37 are not in contact with the supports 33 and 34 and are separated. The inclination angle of the plurality of dishes 37 varies depending on the diameter of the dish 37 when the predetermined space (L2) is constant, and the inclination angle (θ3) becomes smaller when the diameter of the dish 37 is larger. . Moreover, the space | interval (S2) of the lower side peripheral edge part 37c of the mutually adjacent dishes 37 will be in the state wider than the space | interval (S3) of the upper side peripheral edge part 37c.

  The height of the peripheral end 37c on the upper side of the plurality of dishes 37 gradually decreases from the peripheral end 37c of the dish 37 located at the rear end to the peripheral end 37c of the dish 37 located at the top. Yes. As a result, as shown in FIG. 8, a step (S5) is formed in the height direction of the peripheral end portion 37c of the plates 37 adjacent to each other, and the plates 37 adjacent to each other are part of the front surface 37a side and the back surface 37b side. By contacting (for example, the yarn bottom 37d), an interval (S3) is formed between the peripheral end portions 37c. Further, since the plurality of dishes 37 are folded so as to be inclined at a predetermined angle (θ3) in the same direction, the peripheral end portion 37c on the upper side of the dish 37 located at the head and the frame 17 of the storage tool 14 are arranged. (S4) is formed between the two. Further, as shown in FIG. 8, when a part (for example, a thread bottom 37 d) of the back surface 37 b side of the plate 37 positioned at the tail is in contact with the base plates 16, 27, the upper side of the plate 37 positioned at the tail. An interval (S6) is formed between the peripheral end portion 37c of the base plate 16 and the base plates 16 and 27.

  Further, in this embodiment, the rod-like supports 22, 23, 33, 34 having a circular cross section and the peripheral end portion 37c of the plate 37 are almost in point contact, and slip resistance can be reduced. The supports 22, 23 and 33, 34 are preferably processed surfaces having good smoothness, or at least the surface thereof is preferably a resin or the like. In this case, the supports 22, 23, 33, 34 and the peripheral edge 37c of the dish 37 are used. And the movement of the plate 37 can be made smooth, and the separating operation and the posture change of the plates 37 adjacent to each other during cleaning can be more reliably performed.

  In addition, it is necessary to consider the storage tool after storing tableware so that it can be easily carried and the loading and unloading operations into the cleaning device can be easily performed. For this reason, although it changes with kinds, shapes, masses, etc. of tableware, especially the number of the dishes 37 accommodated in the storage tool 14 from the surface of total mass is preferable about 20-40 pieces.

  Further, the number, the cross-sectional shape, the arrangement position, etc. of the supports 22, 23 and 33, 34 of the storage device 14 are not limited to the embodiment, but the shape, size, mass, material of the tableware (dish 37) The optimum conditions may be set in consideration of the inclination posture of the tableware during washing and the stability of the movement from the inclination posture in the vertical direction. In the embodiment, since the cleaning is performed with the storage unit 15 facing down and the storage tool 14 in a horizontal (lateral) position, the mass of the plurality of dishes (dish 37) is used to support the support members 22 and 23 of the storage unit 15. Will receive and support. Therefore, the number of the supports 22 and 23 of the storage unit 15 may be larger than the number of the supports 33 and 34 of the holding unit 26, and in this case, the stability can be further improved.

  As described above, the storage device 14 according to the present invention has the peripheral ends 37c of the plurality of dishes 37 that freely slide the support bodies 22, 23, 33, and 34, and move along the overlapping direction. The positions of only the front surface 37a side of the plate 37 and the rear surface 37b side of the plate 37 positioned at the rear are regulated by the base plates 16 and 27 and the frames 17 and 28 as position regulating members, and the front surface 37a side and the back surface are regulated. A plurality of dishes 37 with the 37b side overlapped in the horizontal direction are stored so that movement along the stacking direction and change in posture in the vertical direction can be freely performed within a predetermined range.

  As a result, there is no need to support the peripheral end portions 37c of the individual dishes 37 as in the prior art, and the dishes 37 having a variation in dimensions, the dishes 37 close to each other (outer edge) between the peripheral end portions 37c, and the eating The dishes 37 to which the solid matter such as the remaining left rice and meat pieces are adhered can be stacked and inserted into the storage device as they are. In addition, it is not necessary to check the degree of fitting of the plurality of dishes 37, and the storage and take-out of the plurality of dishes 37 can be made extremely easy and the storage property can be improved.

  Furthermore, conventionally, since the peripheral end portion 37c of each plate 37 is supported, stress may be applied to the plate 37 by the support member, and there is a risk that the tableware may be damaged during storage, removal, carrying, transportation by a vehicle, and the like. there were. On the other hand, since the storage device of the present invention does not need to support the peripheral ends of the individual dishes 37, the above-described damage does not occur.

  Further, only a predetermined space may be provided and stored with respect to the total length of the stacked dishes 37, and the plurality of dishes 37 can be stored in a compact manner, so that the storage tool itself can be reduced in size and weight. Furthermore, due to the simplification of the structure, there are few components that obstruct the flow of the cleaning water sprayed to the plurality of dishes 37 stored in the storage tool, and the plurality of dishes 37 can be reliably cleaned. In addition, the storage device itself can be reliably cleaned, and the dirt component of the plurality of dishes 37 is caught and does not remain in the storage device. Thus, the structure of the storage tool can be simplified and the storage performance of the dish 37 can be improved.

  When the storage device 14 is placed in a horizontal (lateral) position with the storage unit 15 down, the center of gravity of the plate 37 is positioned on the back surface 37b side of the plate 37, so that the plurality of plates 37 are on the back surface 37b side. The peripheral end portion 37c slides on the support 22, 23, 33, 34 with the lower side facing downward, and the plurality of dishes 37 are inclined at a predetermined angle (θ3) in the same direction so that a part of them is in contact with each other and folded. It will be. Thus, it is not necessary to support the individual dishes 37 and operate the support mechanism to incline the plurality of dishes 37, and the plurality of dishes 37 are inclined only by placing the storage device 14 in the horizontal direction. The operation work at the time of cleaning can be simplified. Further, the plurality of dishes 37 can be charged and transported to the cleaning device in a stabilized state.

  Further, the plurality of dishes 37 are accommodated such that the interval between the lower peripheral end portions 37c of the adjacent dishes 37 is larger than the interval between the upper peripheral end portions 37c. As a result, the plurality of dishes 37 can be loaded and transported to the cleaning device in a more stabilized state. Moreover, when storing after washing | cleaning, the washing water adhering to the surface 37a side and the back surface 37b side of the dish 37 tends to flow out, and can dry more quickly.

  Next, based on FIGS. 9 to 12, basic washing operation, action, and dish separation and posture state change in washing will be described. In the figure, W indicates the flow of the jetted cleaning water.

  FIG. 9A shows a cleaning state of the surface 37a of the dish 37 stored in the storage tool 14 located at the head in the moving direction. The washing water is sprayed from the nozzles 10 and 11 to the interval (S4) in a direction crossing each other. As a result, the washing water from the nozzles 10 and 11 becomes a collision flow on the surface 37a of the dish 37 and diffuses to remove dirt. In particular, the cleaning water splashes between the surface 37a portion of the dish 37 and the frames 17 and 28 and strikes the surface 37a portion to reliably remove the dirt.

  In the state of FIG. 9A, the plurality of dishes 37 are inclined at a predetermined angle, but the washing water from the nozzles 10 and 11 gives dynamic pressure to the surface 37 a of the dish 37, As the washing water flows from above to below the space between the surface 37a and the frames 17, 28, the lower portion of the surface 37a of the dish 37 is separated from the frames 17, 28 as shown in FIG. 9B. Then, the plurality of dishes 37 positioned from the head to the tail changes from a posture inclined at a predetermined angle to a substantially vertical posture. Further, the washing water flows from the upper side to the lower side of the space between the surface 37a portion of the plate 37 and the frames 17 and 28, thereby removing dirt on the surface 37a of the plate 37.

  FIG. 10A shows the peripheral edge 37c of the dish 37 in which the storage tool 14 is moved by the conveyor 2 with respect to the nozzles 10 and 11 fixedly arranged from the state of FIG. Indicates the state of hitting. The washing water sprayed from the nozzles 10 and 11 has a predetermined width, and the washing water has a velocity distribution in which the flow velocity at the central portion is faster than the flow velocity at the outer peripheral portion. Furthermore, the thickness (width) of the peripheral end portion 37c is small and has a structure having a predetermined curvature. As a result, the washing water is diverted to both sides of the peripheral end portion 37 c when it hits the peripheral end portion 37 c of the dish 37, and the proportion of the flow rate changes in a very short time due to the movement of the storage tool 14. The width in the moving direction of the storage device 14 for the cleaning water sprayed from the nozzles 10 and 11 does not need to be narrowed, and may be, for example, about the pitch dimension of the peripheral end portions 37c of the plates 37 adjacent to each other.

  Therefore, the amount of the diversion component of the washing water from the peripheral edge 37c of the tray 37 positioned at the head to the frames 17 and 28 due to the movement of the storage tool 14 is adjacent to the peripheral edge 37c of the tray 37 positioned at the head. When the amount of the diversion component of the washing water to the second dish 37 side is larger, the surface 37a portion of the dish 37 and the frames 17, 28 are in a separated state as shown in FIG. 9B.

  Furthermore, the amount of the diversion component of the washing water from the peripheral end portion 37c of the dish 37 positioned at the head to the adjacent second dish 37 side by the movement of the storage tool 14 is the peripheral edge portion 37c of the dish 37 positioned at the head. If the amount of the diversion component of the washing water from the frame 17 to the frame 17 or 28 becomes larger, the dynamic pressure and static pressure of the washing water that has entered the interval (S3) between the upper peripheral end portions 37c are located at the top. 10 acts on the back surface 37b of the second plate 37 and the front surface 37a of the second plate 37 to spread them, and the plate 37 located at the head as shown in FIG. , 33 and 34, the peripheral end 37c slides and contacts the frames 17 and 28. At the same time, the plate 37 located at the head and the second plate 37 adjacent to each other are separated from each other.

  Washing water flows from the upper part to the lower part and from the upper part to the lateral part in the spaced intervals, and the dirt on the back surface 37b of the tableware 37 located at the top and the surface 37a of the second tableware 37 is removed and washed. is there. When the cleaning water flows in the spaced intervals, the dirt on the front surface 37a and the back surface 37b of the tableware 37 can be surely removed and the formation of the spaced intervals can be maintained.

  As described above, since the ratio of the partial flow rate changes in a very short time due to the movement of the storage tool 14, the transition from the state shown in FIG. 10 (a) to FIG. 10 (b) is performed almost instantaneously. The plurality of dishes 37 stored in 14 are maintained in a substantially vertical posture. In the state shown in FIG. 10B, dirt on the surface 37a of the second dish 37 adjacent to the back surface 37b of the dish 37 positioned at the head is removed by the flow of the washing water.

  In the state shown in FIGS. 10A and 10B, the plurality of dishes 37 stored in the storage device 14 is maintained in a substantially vertical posture, and is stored at a predetermined angle (θ3). The interval (S3) between the upper peripheral end portions 37c is substantially the same as the interval (S1) between the peripheral end portions 37c when the plates 37 are stacked in the vertical direction and stored in the storage tool 14. As a result, the interval between the peripheral end portions 37c on the upper side of the plates 37 adjacent to each other is widened, and the cleaning water is more likely to enter the interval between the peripheral end portions 37c of the plates 37 adjacent to each other.

FIG. 11A shows the peripheral edge of the dish 37 in which the storage tool 14 is moved by the conveyor 2 with respect to the nozzles 10 and 11 fixedly arranged from the state of FIG. The state which hits 37c is shown. Similar to the state change in FIGS. 10 (a) and 10 (b),
The amount of the diversion component of the wash water from the peripheral end portion 37c of the second dish 37 to the first dish 37 side by the movement of the storage tool 14 is changed from the second to the third dish 37 side adjacent to the second dish 37. When it is larger than the amount of the diversion component of the washing water, the back surface 37b of the dish 37 located at the head and the surface 37a of the dish 37 located second are in a separated state as shown in FIG.

  Furthermore, the amount of the diversion component of the washing water from the peripheral end portion 37c of the second dish 37 to the adjacent third dish 37 side by the movement of the storage tool 14 is the peripheral edge of the second dish 37. When the amount of the diversion component of the washing water from the portion 37c to the top plate 37 is increased, the second plate 37 is supported to the top plate 37 as shown in FIG. The body 22, 23, 33, 34 is slid and moved to contact the top plate 37, and at the same time, the second plate 37 and the adjacent third plate 37 are separated from the contacted state. .

  As described above, since the ratio of the partial flow rate changes in a very short time due to the movement of the storage device 14, the state transition from FIG. 11 (a) to FIG. 11 (b) is performed almost instantaneously. The plurality of dishes 37 stored in 14 are maintained in a substantially vertical posture. In the state shown in FIG. 11B, dirt on the surface 37a of the third dish 37 adjacent to the back surface 37b of the second dish 37 is removed by the flow of the washing water. Thereafter, the same operation and action as described above are repeated by moving the storage tool 14, and the tableware 37 stored in the storage tool 14 is sequentially washed.

  FIG. 12A shows a cleaning state when the cleaning water from the nozzles 10 and 11 is moved to the position of the rear surface 37b of the dish 37 located at the end by the movement of the storage tool 14. The cleaning water of the nozzles 10 and 11 enters the space (S6) between the back surface 37b of the plate 37 located at the tail and the base plates 16 and 27, and is located at the surface and the tail of the base plates 16 and 27 of the storage device 14. The rear surface 37b of the plate 37 located at the rear end is removed and cleaned by repeatedly colliding with the back surface 37b of the plate 37. The plurality of dishes 37 stored in the storage device 14 is in a substantially vertical orientation when the back surface 37b of the dish 37 located at the rearmost end is pushed by the cleaning water.

  In general, the back surface of the tableware is less dirty than the surface of the tableware, but the above operation reliably removes the stain on the back surface 37b of the plate 37 located at the tail. In the cleaning state shown in FIGS. 9 to 12, the container 14 itself is also cleaned by the flow of the cleaning water sprayed from the nozzles 10 and 11 and the cleaning water from the dish 37.

  FIG. 12B shows the cleaning when the cleaning water from the nozzles 10 and 11 is moved to a position away from the base plates 16 and 27 of the storage tool 14 by the movement of the storage tool 14 from the state of FIG. Indicates the state. At this time, since the washing water from the nozzles 10 and 11 does not hit the plurality of dishes 37, the plurality of dishes 37 return to a state inclined at a predetermined angle (θ3) as in the case of storage as shown in FIG. Become.

  As described above, the cleaning operation shown in FIGS. 9 to 12 is performed in each of the rough cleaning zone 7a, the intermediate cleaning zones 7b and 7c, and the finishing cleaning zone 7d, and the cleaning of the dish 37 stored together with the storage tool 14 is completed. . The dish 37 that has been cleaned is stored in the storage tool 14 by being dried, sterilized, or the like in the next step. In one cleaning zone, the cleaning operation shown in FIGS. 9 to 12 may be performed a plurality of times by moving the storage device 14 in one direction, and the cleaning operation is selected as necessary.

  As described above, in the basic cleaning method of the present invention, the peripheral end portion 37c of the plate 37, which is a plurality of tableware in which the front surface 37a side and the back surface 37b side are stacked in the horizontal direction, is formed in a plurality of supports along the stacking direction. 22, 23, 33, and 34, and among the plurality of dishes 37, the position on the front surface 37 a side of the dish 37 positioned at the top and the position of the back surface 37 b side of the dish 37 positioned at the rearmost is a position regulating member. The base plates 16 and 27 and the frames 17 and 28 are regulated so that the plurality of dishes 37 are stored in the storage tool 14 so that movement and posture change along the stacking direction can be freely performed within a predetermined range. 14, the cleaning water is sequentially sprayed from the nozzles 10 and 11 along the overlapping direction to the peripheral ends of the plurality of dishes 37 stored in 14, and the adjacent dishes 37 in contact with each other by the cleaning water sprayed from the nozzles 10 and 11. To separate, The flow of the washing water flowing between the intervals in which successively to clean the plurality of disc 37.

As described above, the peripheral end portion 37c is supported and restrained for each individual plate 37, and the movement and change in posture in the stacking direction are freely stored within a predetermined range without being restricted, and the stacking direction is accommodated in the peripheral end portion 37c. It injects sequentially along. As a result, the individual dishes 37 immediately follow the flow of the washing water and swing, and the adjacent dishes 37 are separated while sequentially repeating the contact state and the non-contact state. When flowing in the interval in which the wash water is separated, that Ki out to hold the form of spaced intervals with reliably remove dirt.

  In addition, the plates 37 move and swing along the plurality of supports 22, 23, 33, 34 while sequentially repeating the contact state and the non-contact state in which the plates 37 are separated from each other, and the plates 37 that are adjacent to each other. Will contact each other at a high speed. By this movement and recoil at the time of contact, dirt attached to the dish 37 can be removed, and peeling of the residue can be promoted to improve the cleaning performance. Furthermore, the movement of the peripheral end portion 37c of the dish 37 can surely remove the contamination of the peripheral end portion 37c portion and the storage device 14 itself.

  In this manner, the support of the peripheral end portion 37c of each dish 37 is not required, and the plurality of dishes 37 are stored in the storage device 14 with a predetermined space necessary for the washing water to flow between the dishes 37 adjacent to each other. The storage tool 14 can be reduced in size. As a result, a larger number of storage devices 14 can be put into the cleaning device at the same time for cleaning. Further, as described above, the plates 37 adjacent to each other can be instantaneously separated and the dirt can be reliably removed. Therefore, it is possible to reliably and efficiently remove the dirt on the dish 37 stored compactly in the storage tool.

  Further, in the present embodiment, the wash dishes sprayed from the nozzles 10 and 11 change the plurality of dishes 37 stored in a posture inclined at a predetermined angle into a substantially vertical posture and separate the adjacent plates 37 that are in contact with each other. They are separated. When the individual dishes 37 are supported in a vertical posture as in the prior art, and cleaning water is sprayed between the dishes 37 for cleaning, the cleaning water does not sufficiently contact the front surface 37a and the back surface 37b of the dish 37. Since it flows, there is a possibility that dirt cannot be removed reliably. On the other hand, it is changed to a substantially vertical posture by the flow of the cleaning water sprayed from the nozzles 10 and 11, and the dishes 37 adjacent to each other are reliably separated from each other, and the cleaning water is supplied to the surface 37 a of the dish 37. In addition, the fluid flows in contact with the back surface 37b, and by adopting a substantially vertical posture, it is possible to promote the fall of the dirt component and remove the dirt reliably.

  Further, by spraying the cleaning water from the plurality of nozzles 10 and 11 to the peripheral end portion 37c of the dish 37 along the overlapping direction, the dish 37 is separated in a stable state and sufficient washing water is separated. The dirt can be surely removed by entering the gap. Further, by injecting the cleaning water from the plurality of nozzles 10 and 11 in the direction intersecting with each other at the interval between the peripheral end portions 37c of the plate 37, the cleaning water from the plurality of nozzles 10 and 11 is separated from the collision flow within the interval. Thus, a high-speed washing water flow that diffuses and discharges outward from the peripheral end portion 37c side where no washing water is jetted can be formed, and dirt can be reliably removed.

  The dimension of the predetermined space (L2) may be set to an optimum condition in consideration of an inclination angle (θ3) with respect to the vertical surface of the plurality of dishes 37 and a necessary separation distance when cleaning the dishes 37 adjacent to each other. If the inclination angle (θ3) is too large, the posture of the dish 37 varies and becomes unstable. The separation distance may be a dimension in which the cleaning water flows over the entire surface 37a and back surface 37b of the plates 37 adjacent to each other, and does not require a large distance. Although depending on the type, shape, size, mass, and the like of the plate 37, the inclination angle (θ3) is set to 5 to 10 degrees, for example, and the separation distance is set to 10 to 20 millimeters, for example. Therefore, the dish 37 can be stored compactly in the storage tool 14 and can be washed in this state.

  Further, the moving speed of the storage device 14 correlates with the amount and speed of washing water jetting and the time during which the washing water flows while the adjacent dishes 37 are separated from each other. If the speed is made slower and if there is little dirt, the moving speed should be made faster and set according to the situation. The moving speed of the normal storage tool 14 is set to 0.5 to 1 meter per minute, for example.

  In the above-described cleaning state, the plurality of dishes 37 were changed from the posture inclined at a predetermined angle by the cleaning water to the substantially vertical posture, but the posture inclined at the predetermined angle (θ3) was slightly changed to the vertical direction to incline the posture. Alternatively, the plates 37 adjacent to each other may be separated from the contact state to the non-contact state, and the cleaning water may be flowed to perform cleaning. In this case, the distance between the upper sides of the plates 37 adjacent to each other in a non-contact state is as narrow as, for example, 10 millimeters or less. It can be washed by flowing into the space 37c and further flowing downward from the dish 37.

  The angle of change of the posture of the dish 37 from the posture inclined at a predetermined angle (θ3) to the vertical direction is, for example, the amount of washing water from the nozzles 10, 11, the jetting speed, and the movement of the container 14 within the washing space 7. Can be adjusted by speed etc. By adjusting at least one of reducing the amount of cleaning water from the nozzles 10 and 11, reducing the spraying speed, and increasing the moving speed of the storage tool 14 in the cleaning space 7. The change angle of the posture in the vertical direction tends to be small, and the spacing between the upper sides of the adjacent tableware is also narrowed. What is necessary is just to set this to optimal conditions with the shape of a tableware, mass, and the grade of dirt.

  Further, when the washing water is jetted while being inclined while reducing the change angle of the posture in the vertical direction from the posture inclined by the predetermined angle (θ3) of the plate 37, as shown in FIGS. 7 and 8, they are adjacent to each other. A step (S5) is formed in the height direction of the peripheral end portion 37c of the plate 37, and the nozzles 10 and 11 are provided with a predetermined angle (θ1) with respect to the vertical plane, whereby the nozzle 10 The washing water sprayed from 11 and 11 is caught by hitting the step (S5) portion, and easily enters the interval between the peripheral end portions 37c on the upper side of the plate 37.

  Due to the action of trapping the washing water by the step (S5) described above, the plurality of dishes 37 can be sequentially separated and washed in the inclined posture. In this case, the plurality of dishes 37 stored in the storage tool 14 are also inclined.

  Although not shown, the container 14 is moved back and forth by a driving means from one direction to clean the dish 37, or the container 14 is fixed and the nozzles 10 and 11 are moved back and forth by the driving means. By washing the dish 37, it is possible to reduce the size of the washing apparatus and save space. This is particularly suitable when the number of dishes 37 to be cleaned is relatively small.

  Although there is a bowl as a round tableware, the storage tool and the cleaning method have the same configuration, cleaning operation, action, and effect as the dish 37.

  The basic configuration and the cleaning operation are as described above, but the cleaning water sprayed from the plurality of nozzles shown in FIGS. 13 to 18 toward the dish 37 with respect to means for generating different flow trajectories at intervals separated in each cleaning zone. A description will be given based on the state diagram.

  FIGS. 13A to 13D are state diagrams of the cleaning water sprayed from the plurality of nozzles 10 and 11 toward the dish 37. C1 to C4 in the figure indicate the positions of intersections of the cleaning water sprayed from the plurality of nozzles 10 and 11 toward the dish 37 in the direction intersecting each other, and T1 to T4 are sprayed from the plurality of nozzles 10 and 11. The position of the contact portion where the washed water first reaches the dish 37 is shown. Θ2a to θ2d indicate angles between the cleaning water sprayed from the nozzles 10 and 11, respectively. The nozzles 10 and 11 have a quadrangular (rectangular) cross section for spraying the cleaning water, the long side is in a direction perpendicular to the stacking direction of the dishes 37 stored in the storage device 14, and the short side is along the stacking direction of the dishes 37. Is arranged. From the nozzles 10 and 11, for example, cleaning water is sprayed in a square shape (rectangle) of 3.0 mm × 50 mm, and the narrow 3 mm side is sprayed in a direction along the stacking direction of the dishes 37. Accordingly, in FIGS. 13A to 13D, the wash water having a width of 50 millimeters is sprayed from the nozzles 10 and 11 so as to cross each other, and the center portion of the wash water is described as a flow line. . The shapes and dimensions of the nozzles 10 and 11 and the cleaning water are merely examples, and are not limited thereto, and may be arbitrarily set so as to satisfy the optimum conditions.

  As shown in FIGS. 13A to 13D, the distances between the nozzles 10 and 11 are substantially the same, and the angles θ2a to θ2d between the cleaning water sprayed from the nozzles 10 and 11 are set. In order. As a result, the positions of the intersections C1 to C4 of the washing water sprayed from the plurality of nozzles 10 and 11 in a direction intersecting each other are sequentially moved to the lower side (side facing the nozzles 10 and 11) of the dish 37 serving as tableware. At the same time, the position of the contact portion (T1 to T4) where the cleaning water sprayed from the plurality of nozzles 10 and 11 first reaches the plate 37 sequentially moves to the outside (in the direction away) of the plate 37.

  By moving the positions of the intersections C1 to C4 of the washing water and the positions of the contact portions (T1 to T4) where the washing water first reaches the dish 37, the plates 37 adjacent to each other are separated and separated. The wash water flowing into the interval will produce different flow trajectories.

  In the states of FIGS. 13A and 13B, the washing water colliding at the intersection C1 diffuses and spreads in the space spaced apart from the intersection C1 below the dish 37 and in the lateral direction (horizontal direction). Cleaning is performed by removing dirt on the front surface and the back surface of the plates 37 adjacent to each other. Further, the cleaning water sprayed from the nozzles 10 and 11 flows from the contact portion (T1) to the intersection point C1, and cleaning is performed by removing dirt on the front and back surfaces of the plates 37 adjacent to each other.

In the state of FIGS. 13C and 13D, the cleaning water sprayed from the nozzles 10 and 11 travels substantially straight from the contact portion (T1) to the intersection C1 while gradually diffusing in the separated interval. It also flows while maintaining a high-speed (for example, 10 m / sec) injection speed. This removes dirt on the front and back surfaces of the plates 37 adjacent to each other to perform cleaning. Note that the positions of the intersections C1 to C4 of the cleaning water and the positions of the contact portions (T1 to T4) where the cleaning water first reaches the dish 37 are examples, and are not limited thereto .

  Each of the states shown in FIGS. 13 (a) to 13 (d) may be performed in each of the cleaning zones 7a to 7d described above, or may be performed centering on the state shown in FIG. 13 (b), for example. You may make it implement the state shown in FIG.13 (d) in one washing | cleaning zone.

  FIGS. 14A to 14D are state diagrams of cleaning water sprayed from the plurality of nozzles 10 and 11 toward the dish 37. C1 to C4 in the figure indicate the positions of intersections of the cleaning water sprayed from the plurality of nozzles 10 and 11 toward the dish 37 in the direction intersecting each other, and T1 to T4 are sprayed from the plurality of nozzles 10 and 11. The position of the contact portion where the washed water first reaches the dish 37 is shown. Θ2a to θ2d indicate angles between the cleaning water sprayed from the nozzles 10 and 11, respectively.

  13A to 13D, the contact portions T1 to T4 are substantially the same, and the angles θ2a to θ2d between the cleaning water sprayed from the nozzles 10 and 11 are sequentially reduced. The distances between the positions of the nozzles 10 and 11 are respectively set so as to decrease in order. As a result, the positions of the intersections C1 to C4 of the washing water sprayed from the plurality of nozzles 10 and 11 in a direction intersecting each other are sequentially moved to the lower side (side facing the nozzles 10 and 11) of the dish 37 serving as tableware.

  Basically, it is almost the same as the flow trajectory of the cleaning water that has flowed into the spaced intervals described with reference to FIGS. 13A to 13D, and thus description of each state is omitted. Each of the states shown in FIGS. 14 (a) to (d) may be performed in each of the cleaning zones 7a to 7d described above, or may be performed centering on the state shown in FIG. 14 (b), for example. You may make it implement the state shown in FIG.14 (d) in one washing | cleaning zone.

  FIGS. 15A to 15D are state diagrams of the cleaning water sprayed from the plurality of nozzles 10 and 11 toward the dish 37. C1 to C4 in the figure indicate the positions of intersections of the cleaning water sprayed from the plurality of nozzles 10 and 11 toward the dish 37 in the direction intersecting each other, and T1 to T4 are sprayed from the plurality of nozzles 10 and 11. The position of the contact portion where the washed water first reaches the dish 37 is shown. Θ2a to θ2d indicate angles between the cleaning water sprayed from the nozzles 10 and 11, respectively.

  13 (a) to (d) are different from each other in that the angles θ2a to θ2d between the cleaning water sprayed from the nozzles 10 and 11 are substantially the same, the distance between the positions of the nozzles 10 and 11 and the contact portions T1 to T1. In T4, the distance between the contact portions is increased in order. As a result, the positions of the intersections C1 to C4 of the cleaning water sprayed from the plurality of nozzles 10 and 11 in a direction crossing each other are sequentially moved to the lower side of the dish 37 (the side facing the nozzles 10 and 11).

  Basically, it is almost the same as the flow trajectory of the cleaning water that has flowed into the spaced intervals described with reference to FIGS. 13A to 13D, and thus description of each state is omitted. Each of the states shown in FIGS. 15 (a) to 15 (d) may be performed in each of the cleaning zones 7a to 7d described above, or may be performed centering on the state shown in FIG. 15 (b), for example. You may make it implement the state shown in FIG.15 (d) in one washing | cleaning zone.

  13 to 15, the nozzles 10 and 11 are configured as two nozzles. However, the present invention is not limited to this, and as shown in FIG. The position may be changed. Moreover, you may implement the structure which added the nozzle 10n to a part of basic structure shown to FIGS. 13-15, In these cases, the peripheral edge part 37c of the plate | plate 37 accommodated in the storage tool 14 in the some washing | cleaning zone. Thus, the number of the plurality of nozzles for spraying the cleaning water on the nozzles has a different cleaning zone. As a result, the flow trajectory of the wash water that has flowed into the spaced intervals can be made different.

  Moreover, in FIGS. 13-15, the position of the intersection part C1-C4 of the wash water sprayed in the direction which mutually cross | intersects from the some nozzles 10 and 11 is the lower side of the plate | plate 37 which is tableware sequentially (opposite the nozzles 10 and 11). 17 (a) to (d), in addition to the lower side of the plate 37 (the side facing the nozzles 10 and 11), in addition to the horizontal direction (horizontal) of the plate 37, as shown in FIGS. (Direction), the positions of the intersections C1 to C4 may be moved. As a result, the flow trajectory of the wash water that has flowed into the spaced intervals can be made different.

  In addition, in FIGS. 13 to 15, cleaning water having substantially the same injection speed and injection amount is injected from the plurality of nozzles 10 and 11, but as shown in FIG. By making the nozzle 10 side faster than the nozzle 11 or increasing the injection amount on the nozzle 10 side more than the nozzle 11, particularly after colliding at each intersection, the cleaning water is separated within the interval of separation. It becomes easy to diffuse to the area (A1) offset to the side.

  Further, as shown in FIG. 18 (b), by increasing the injection speed on the nozzle 11 side faster than the nozzle 10 or by increasing the injection amount on the nozzle 11 side than the nozzle 10, After the collision, the cleaning water easily diffuses into the region (A2) that is offset toward the nozzle 10 in the separated interval. In these cases, the cleaning water injection speed and / or the injection amount differ between the plurality of nozzles that inject the cleaning water into the plurality of cleaning zones and the peripheral end portion 37c of the dish 37 stored in the storage tool 14. Will have a wash zone. As a result, the flow trajectory of the wash water that has flowed into the spaced intervals can be made different. Further, in FIGS. 13 to 18, the cleaning water having a width of 50 millimeters is sprayed from the nozzles 10 and 11 so as to cross each other, but the cleaning water having this width flows in the spaced interval. Moreover, since it collides and diffuses, the washing water is more likely to flow in all the regions of the front surface 37a and the rear surface 37b of the separated dishes.

  As described above, the cleaning operation of the plurality of dishes 37 stored in the storage device 14 including the cleaning water having different flow trajectories at the spaced intervals is repeated a plurality of times, so that all of the front surface 37a and the back surface 37b of the separated plates The washing water easily flows in the area. Therefore, the dirt adhering to the dish 37 can be reliably removed.

  Further, in this embodiment, a plurality of cleaning zones are provided, and the adjacent dishes 37 that are in contact with each other are separated from each other by the cleaning water sprayed from the nozzle for each of the plurality of cleaning zones, and flows into the spaced intervals. In addition to the cleaning operation for sequentially cleaning the dishes 37 stored in the storage device 14 by the flow of cleaning water, the plurality of cleaning zones have cleaning zones in which the flow trajectory of the cleaning water is different from the others. is there.

  Accordingly, it is possible to arbitrarily configure the number of cleaning zones in which the total number of cleaning zones and the flow trajectory of the cleaning water within the spaced intervals included therein are different from others. Accordingly, not only the specific dish 37 but also various dishes having different shapes and sizes, and the state of dirt attached thereto, the total number of cleaning zones and cleaning water within the spaced intervals included therein are included. It becomes easy to configure a cleaning apparatus that selects the number of cleaning zones with different flow trajectories from each other and sets the optimal cleaning conditions.

  Furthermore, in each of the cleaning zones and in the cleaning zone in which the flow trajectory of the cleaning water is different from the others, as described in FIGS. They can be used in combination. Accordingly, it becomes easy to configure a cleaning device having more optimal cleaning conditions corresponding to various dishes having different shapes, sizes, and the like and the attached state of dirt.

  Next, a basic cleaning method for a rectangular tray serving as tableware will be described with reference to FIGS. The cleaning device is the same as that shown in FIGS. 1 and 2 except for the storage device storing the tray. In addition, although square dishes have a partition plate, the washing method is almost the same as that of the tray.

  19 is an overview perspective view of the tray storage device, FIG. 20 is a top view of the storage device of FIG. 19, FIG. 21 is an overview diagram showing a state in which a plurality of trays are stacked in the vertical direction (vertical direction), and FIG. 23 is a front view showing a state in which the trays stacked in the direction are stored in the storage device, FIG. 23 is a view showing the posture of the tray in a state where the storage device is tilted from the vertical direction to the horizontal direction (lateral direction), and FIG. FIG. 25 to FIG. 28 are diagrams showing the separation of the tray and the change in the posture state during cleaning.

  As shown in the schematic perspective view of the storage tool 38 of the tray 51 in FIG. 19 and the top view of the storage tool 38 in FIG. 20, the storage tool 38 constitutes a storage part 39. The storage unit 39 includes a base plate 40 and a frame 41, and the base plate 40 and the frame 41 are integrated by support columns 42, 43, 44, 45 having a predetermined length. Further, rod-like supports 46, 47, 48, and 49 having a circular cross section are fixed between the base plate 40 and the frame 41.

  As shown in FIGS. 21 and 22, trays 51 that are unwashed tableware after eating are stacked in a vertical direction (vertical direction) by a predetermined number (for example, 20 to 40) with the surface 51 a of the tray 51 facing upward. This is stored as a unit in the storage part 39 of the storage tool 38 in a vertical posture. The back surface 51b of the lowermost tray 51 is placed on the base plate 40, and is pushed in from the insertion port 50 until the peripheral end 51c of the tray 51 contacts the supports 48 and 49. A predetermined number of trays 51 stacked vertically are supported by a plurality of support portions 46, 47, 48, 49 at a plurality of peripheral end portions 51 c and stored therein. Further, when the stacked trays 51 are stored in the storage tool 38, the uppermost tray 51 and the frame 41 are set to have a predetermined space (L5) with respect to the height (L4) of the stacked trays 51. It is what. (S7) indicates the interval between the peripheral end portions 51c of the adjacent trays 51. The predetermined space (L5) is set to 10 to 20 millimeters, for example.

  The trays 51 are stacked in the vertical direction, and the trays 51 are stored in the storage tool 38 in the vertical position as a unit. However, the stacked trays 51 can be stored in the storage tool 38 in the horizontal position. .

  The storage tool 38 can be moved by holding the columns 42 and 43 by hand, but a handle (not shown) may be provided. Further, although a support for preventing the stored tray 51 from coming off from the storage tool 38 is not provided, a holding part (not shown) that opens and closes like the storage tool 14 may be provided and held from the entire circumference.

  After the plurality of trays 51 are stored in the storage tool 38, the storage tool 38 is placed in a horizontal posture and placed on the conveyor 2 in the cleaning space 7. FIG. 23 shows the posture state of the plurality of trays 51 when the storage tool 38 is changed from the vertical direction to the horizontal direction.

  As described above, when the stacked trays 51 are stored in the vertical storage tool 38, a predetermined space (L5) is formed between the uppermost tray 51 and the frame 41 with respect to the height (L4) of the stacked trays 51. ). The lower part on the front surface 51a side of the first tray 51 is in contact with the frame 41 (position regulating member), and the upper peripheral end 51c on the rear surface 51b side of the rearmost tray 51 or a part of the tray 51 is the base plate 40 (position). The position of both ends is regulated in contact with the regulating member. Thus, the plurality of trays 51 stacked in the horizontal direction are accommodated so that movement along the stacking direction and change in posture in the vertical direction can be freely performed within a predetermined range.

  When the storage tool 38 is set in the horizontal direction, the center of gravity of the tray 51 is positioned on the back surface 51b side of the tray 51, so that the plurality of trays 51 have the back end 51b side of the tray 51 facing down and the peripheral end portion 51c is the support 46. , 47, 48, and 49, and a part of them are in contact with each other and folded so as to be folded in the same direction at a predetermined angle (θ4). In addition, the inclination angle of the tray 51 is different between the tray 51 located at the head and the tray 51 located at the tail, and the tray 51 located at the tail is located on the side of the tray 51 located at the tail. The inclination angle gradually decreases with the direction.

  Further, the lower peripheral end portion 51c of the plurality of inclined trays 51 is in contact with the supports 48, 49, and the tray 51 positioned at the rearmost position has the maximum inclination angle (θ4) of the tray 51 positioned at the head. Since the inclination angle gradually decreases in the lateral direction, the height of the peripheral end portion 51c on the upper side of the plurality of trays 51 is first from the peripheral end portion 51c of the tray 51 located at the end. It is in a state of gradually lowering toward the peripheral end portion 51c of the tray 51 located in the position.

  24, a plurality of trays 51 are stored in the storage tool 38, and the tray 51 positioned at the upper peripheral end 51c and the rearmost portion of the tray 51 positioned at the top when the storage tool 38 is set in the horizontal direction. The partially enlarged view of the peripheral edge part 51c of the upper side of is shown.

  The height of the peripheral end 51c on the upper side of the plurality of trays 51 is gradually lowered from the peripheral end 51c of the tray 51 located at the end to the peripheral end 51c of the tray 51 located at the top. Yes. As a result, as shown in FIG. 24, a step (S10) is formed in the height direction of the peripheral end portion 51c of the adjacent trays 51, and the adjacent trays 51 are part of the front surface 51a side and the back surface 51b side. Makes a gap (S7) between the peripheral ends 51c.

  Further, since the plurality of trays 51 are folded so as to be inclined at a predetermined angle (θ4) in the same direction, the upper peripheral end portion 51c of the tray 51 located at the head and the frame of the storage tool 38 are arranged. An interval (S9) is formed between the terminal 41 and the terminal 41. Further, as shown in FIG. 24, when a part of the rear surface 51b side of the tray 51 located at the rearmost part contacts the base plate 40, the peripheral end 51c on the upper side of the tray 51 located at the rearmost side and the base A space (S11) is formed between the plate 40 and the plate 40.

  Hereinafter, based on FIGS. 25 to 28, the cleaning operation, the action, and the separation of the tray 51 and the change in the posture state in the cleaning will be described. The cleaning apparatus has the same basic configuration as that shown in FIGS. 1 and 2, and differs only in that the storage tool 38 storing the tray 51 is inserted to perform cleaning. In the figure, W indicates the flow of the jetted cleaning water.

  FIG. 25A shows a cleaning state of the surface 51a of the tray 51 stored in the storage tool 38 positioned at the head in the moving direction. Wash water is sprayed from the nozzles 10 and 11 to the interval (S9) in a direction crossing each other. As a result, the cleaning water from the nozzles 10 and 11 becomes a collision flow on the surface 51a of the tray 51 and diffuses to remove dirt. In particular, the cleaning water splashes between the surface 51a of the tray 51 and the frame 41 and strikes the surface 51a while repelling, so that the dirt is surely removed.

  In the state of FIG. 25A, the plurality of trays 51 are inclined at a predetermined angle, but the washing water from the nozzles 10 and 11 applies dynamic pressure to the surface 51 a of the tray 51, and the surface of the tray 51 As the washing water flows from above to below the space between the frame 51a and the frame 41, as shown in FIG. 25 (b), the lower part of the surface 51a of the tray 51 is separated from the frame 41, and from the head to the tail. The plurality of trays 51 positioned in the position change from a posture inclined at a predetermined angle to a substantially vertical posture. Further, the cleaning water flows from the upper side to the lower side of the space between the surface 51a of the tray 51 and the frame 41, and the dirt on the surface 51a of the tray 51 is removed.

  FIG. 26A shows the peripheral end 51c of the tray 51 in which the storage tool 38 is moved by the conveyor 2 with respect to the nozzles 10 and 11 fixedly arranged from the state of FIG. Indicates the state of hitting. The washing water sprayed from the nozzles 10 and 11 has a predetermined width, and the washing water has a velocity distribution in which the flow velocity at the central portion is faster than the flow velocity at the outer peripheral portion. Further, the thickness (width) of the peripheral end portion 51c is small and has a structure having a predetermined curvature. As a result, when the washing water hits the peripheral end portion 51c of the tray 51, it is diverted to both sides of the peripheral end portion 51c, and the proportion of the flow rate changes in a very short time due to the movement of the storage tool 38.

  Accordingly, the amount of the diversion component of the washing water from the peripheral end 51c of the tray 51 positioned at the head to the frame 41 side by the movement of the storage tool 38 is the second adjacent from the peripheral end 51c of the tray 51 positioned at the head. When the amount of the diversion component of the washing water to the tray 51 side is larger, the surface 51a of the tray 51 and the frame 41 are in a separated state as shown in FIG.

  The amount of the diversion component of the washing water from the peripheral end portion 51c of the tray 51 positioned at the head by the movement of the container 38 to the adjacent second tray 51 side is changed from the peripheral end portion 51c of the tray 51 positioned at the head to the frame. When the amount of the diversion component of the wash water to the 41 side becomes larger, the dynamic pressure and static pressure of the wash water entering the interval (S7) of the peripheral end 51c are positioned at the head as shown in FIG. Acting on the back surface 51b of the tray 51 and the front surface 51a of the second tray 51 to spread them, and the tray 51 located at the top has the supports 46, 47, 48, 49 on the side of the frame 41 and the peripheral end 51c. It slides and moves to contact the frame 41, and at the same time, the tray 51 located at the head and the adjacent second tray 51 are separated from the contacted state.

Wash water flows from the upper part to the lower direction and from the upper part to the lateral direction in the spaced intervals, and the dirt on the back surface 51b of the tray 51 located at the head and the surface 51a of the second tray 51 is removed and washed. is there. Together reliably removing dirt when flowing in the wash water is separated intervals, that Ki out to hold the form of spaced-apart intervals.

  As described above, since the ratio of the partial flow rate changes in a very short time due to the movement of the storage tool 38, the state transition from FIG. 26 (a) to FIG. 26 (b) takes place almost instantaneously. The plurality of trays 51 housed in 38 are maintained in a substantially vertical posture. In the state shown in FIG. 26 (b), dirt on the front surface 51a of the second tray 51 adjacent to the back surface 51b of the tray 51 located at the head is removed by the flow of cleaning water.

  FIG. 27A shows the peripheral end of the tray 51 where the storage device 38 is moved by the conveyor 2 relative to the nozzles 10 and 11 fixedly arranged from the state of FIG. A state of hitting 51c is shown. Similarly to the state change in FIGS. 26 (a) and 26 (b), the washing water from the peripheral end portion 51c of the tray 51 positioned second by the movement of the storage tool 38 to the tray 51 side positioned at the head is provided. When the amount of the diversion component is larger than the amount of the diversion component of the washing water from the second to the adjacent third tray 51, the rear surface 51b of the tray 51 located at the head and the tray 51 located second. The surface 51a is in a separated state as shown in FIG.

  Furthermore, the amount of the diversion component of the washing water from the peripheral end portion 51c of the second tray 51 positioned next to the adjacent third tray 51 by the movement of the storage tool 38 is the peripheral end of the second tray 51. When the amount of the diversion component of the washing water from the portion 51c to the head tray 51 side becomes larger, the second tray 51 moves to the head tray 51 side as shown in FIG. Then, the first tray 51 is contacted, and at the same time, the second tray 51 and the adjacent third tray 51 are separated from the contact state.

  As described above, since the ratio of the divided flow rate changes in a very short time due to the movement of the storage tool 38, the transition from the state shown in FIG. 27 (a) to FIG. 27 (b) is performed almost instantaneously. The plurality of trays 51 housed in 38 are maintained in a substantially vertical posture. In the state shown in FIG. 27B, the dirt on the front surface 51a of the third tray 51 adjacent to the back surface 51b of the second tray 51 is removed by the flow of the washing water. Thereafter, the same operation and action as described above are repeated by the movement of the storage tool 38, and the tray 51 stored in the storage tool 38 is sequentially washed.

  FIG. 28A shows a cleaning state when the cleaning water from the nozzles 10 and 11 is moved to the position of the back surface 51b of the tray 51 located at the end by the movement of the storage tool 38. FIG. The cleaning water of the nozzles 10 and 11 enters the space (S11) between the back surface 51b of the tray 51 located at the tail and the base plate 40, and the tray 51 located at the tail and the surface of the base plate 40 of the storage tool 38. The collision with the back surface 51b is repeated, and the back surface 51b of the tray 51 located at the tail is removed and cleaned. The plurality of trays 51 stored in the storage tool 38 are in the vertical direction when the back surface 51b of the tray 51 located at the tail is pushed by the cleaning water.

  In general, the back surface is less dirty than the front surface of the tray 51, but the above-described action reliably removes the stain on the back surface 51b of the tray 51 located at the end. 25 to 28, the container 38 itself is also cleaned by the flow of the cleaning water sprayed from the nozzles 10 and 11 and the cleaning water from the tray 51.

  FIG. 28B shows a cleaning state when the cleaning water from the nozzles 10 and 11 is moved to a position away from the base plate 40 of the storage tool 38 by the movement of the storage tool 38 from the state of FIG. Show. At this time, since the washing water from the nozzles 10 and 11 does not hit the plurality of trays 51, as shown in FIG. 23, the plurality of trays 51 return to the state inclined at a predetermined angle (θ4) as in the storage. Become.

  As described above, the cleaning operation shown in FIGS. 25 to 28 is performed in the rough cleaning zone 7a, the intermediate cleaning zones 7b and 7c, and the finishing cleaning zone 7d, and the cleaning of the tray 51 stored together with the storage tool 38 is completed. The tray 51 that has been cleaned is stored in the storage tool 38 by being dried, sterilized, or the like in the next step while being stored. In one cleaning zone, the cleaning operation shown in FIGS. 25 to 28 may be performed a plurality of times by one-way movement of the storage tool 38, and is selected as necessary.

  The storage device 38 of the tray 51 and this cleaning method can obtain the same operations and effects as the example described using the round-shaped dish 37 described above as an example of tableware.

  The basic configuration and the cleaning operation are as described above, but the means for generating different flow trajectories at intervals separated in each cleaning zone is sprayed from a plurality of nozzles toward the dish 37 as shown in FIGS. This can be carried out in the same manner as that shown in the state diagram of the washing water, and will not be described.

(Example 2)
A second embodiment of the present invention will be described below with reference to FIGS. FIG. 29 is a front configuration diagram showing a basic configuration of a cleaning apparatus for performing a dish cleaning method that is a tableware of Embodiment 2 of the present invention, FIG. 30 is a side sectional view taken along line BB of FIG. 29, and FIGS. FIG. 6 is a diagram illustrating the separation of the dishes and the change in posture state during cleaning. A solid line arrow in FIG. 29 indicates a moving direction (conveying direction) of the storage tool 14.

  In the first embodiment, the nozzles 10 and 11 for injecting the cleaning water are arranged from the upper half of the dish 37 to perform cleaning. However, in the second embodiment of the present invention, the lower half of the dish 37 is used. The nozzles 52 and 53 for injecting the cleaning water and the nozzles 54 and 55 for injecting the cleaning water from the upper half are arranged for cleaning. In addition, as the tableware which is a to-be-cleaned object, it is set as the plate | plate 37 demonstrated in Example 1, and this storage tool 14 is demonstrated as common. The same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  As shown in FIGS. 29 and 30, the nozzles 52 and 53 are arranged with a predetermined angle (θ5) across the vertical center in a direction (radial direction of the plate 37) orthogonal to the stacking direction of the plate 37, The washing water is sprayed from the lower half side of 37 toward the substantially central portion of the dish 37. The nozzles 52 and 53 are arranged with a predetermined angle (θ6) with respect to the vertical plane. The nozzles 54 and 55 have a predetermined angle (θ7) across the vertical center, and are arranged at positions where the washing water is jetted from the upper half side of the dish 37 toward the substantially central part of the tableware 37 in the substantially vertical direction. is doing. Further, the distance between each of the nozzles 52, 53, 54, and 55 and the dish 37 is set as close to the peripheral edge of the dish 37 as possible with the largest dish 37 as a base in order to correspond to a plurality of sizes of the dish 37. It is arranged.

  Further, the amount of cleaning water sprayed from the nozzles 52 and 53 from the lower half side of the dish 37 to the peripheral end portion 37c of the dish 37 is set to be the amount of cleaning water sprayed from the nozzles 54 and 55 from the upper half side of the dish 37. Set more than the amount of water. Further, the spraying speed of the cleaning water sprayed from the lower half side of the dish 37 is set faster than the spraying speed of the cleaning water sprayed from the upper half side of the dish 37. It is not necessary to narrow the width in the moving direction of the storage device 14 for the cleaning water sprayed from the nozzles 52 and 53, and it may be, for example, about the pitch size of the peripheral end portions 37 of the plates 37 adjacent to each other. Furthermore, the width in the moving direction (the stacking direction of the dishes 37) of the cleaning water container 14 sprayed from the nozzles 54 and 55 is wider than the width of the cleaning water sprayed from the nozzles 52 and 53 (for example, about 2 to 3 times). It is to be jetted.

  Next, based on FIGS. 31-34, the washing | cleaning operation | movement, an effect | action, and the separation | separation of the dish 37 in washing | cleaning and a posture state change are demonstrated. In the figure, W indicates the flow of the jetted cleaning water. FIG. 31 shows a cleaning state of the dish 37 positioned at the head with respect to the moving direction of the storage tool 14. Washing water is sprayed from the nozzles 54 and 55 to the surface 37a of the dish 37 located at the head, and the dirt on the surface is removed. At this time, since the nozzles 54 and 55 are arranged at a predetermined angle (θ7), the cleaning water is sprayed in a direction intersecting with each other from the upper half side of the plate 37.

  As a result, the washing water from the nozzles 54 and 55 diffuses as a collision flow on the surface 37a of the dish 37, and the dirt is reliably removed. In this state, the pressing force of the washing water acts on the surface 37a of the dish 37 located at the head, so that the plurality of dishes 37 remain inclined at a predetermined angle. At this time, the cleaning water sprayed from the nozzles 52 and 53 from the lower half side of the dish 37 does not reach the lower part of the dish 37 located at the head.

  FIG. 32 shows the lower end of the second plate 37 adjacent to the plate 37 positioned at the head of the storage device 14 moved by the conveyor 2 with respect to the fixedly arranged nozzles 52, 53, 54, 55. The cleaning water from the nozzles 52 and 53 enters the interval (S2) between the nozzles 52 and 53, and the cleaning from the nozzles 54 and 55 increases at the interval between the upper peripheral end portion 37c widened by the entrance of the cleaning water from the nozzles 52 and 53. A state in which water enters and the rear surface 37b of the top plate 37 and the front surface 37a of the second plate 37 are cleaned is shown.

  In FIG. 32, the washing water from the nozzles 52 and 53 passes through the lower peripheral end portion 37 c of the top plate 37 and moves adjacent to the top plate 37 due to the movement of the storage tool 14. It moves to the position of the interval (S2) between the peripheral end portions 37c on the lower side of the second dish 37. At this time, in the interval (S2) between the lower end 37c of the dish 37 located at the head and the second dish 37 adjacent thereto, the direction intersecting each other from the lower half side of the tableware 37 from the nozzles 52 and 53. As the washing water sprayed on enters the upward flow of the washing water, the second and later dishes 37 and the dish 37 located at the head start to change from a tilted posture to a vertical posture.

  Thereby, the space | interval (S3) of the upper side peripheral edge part 37c also becomes wide, and the washing water injected in the direction which mutually cross | intersects from the upper half part side of the plate 37 enters from the nozzles 54 and 55. As a result, as shown in FIG. 32, the pan 37 located at the head makes contact with the frames 17, 28 by sliding the support members 22, 23, 33, 34 to the sides of the frames 17, 28 with the peripheral end 37c sliding. The plate 37 located at the head and the second plate 37 adjacent to each other are separated from the contact state.

  In addition to the amount of washing water and the jetting speed being different between the plurality of nozzles 52, 53 and the nozzles 54, 55, the nozzles 52, 53 are at a predetermined angle (θ6) with respect to the vertical plane as shown in FIG. Since the second tableware 37 is disposed so as to be inclined, it collides with the peripheral end portion 37c on the lower side of the second tableware 37 and the surface 37a of the plate 37 in the vicinity thereof, and the speed energy acts on the second tableware 37. Thus, the second and subsequent plurality of dishes 37 are instantaneously moved from the inclined posture to the vertical posture. Further, a reaction force acts on the back surface 37b of the top plate 37 due to the splash of washing water from the front surface 37a of the second plate 37 on the back surface 37b of the top plate 37. The dish 37 to be changed also changes instantaneously from the tilted posture to the vertical posture.

  When the cleaning water from the nozzles 52 and 53 passes the peripheral end portion 37c on the lower side of the dish 37 located at the head, the transition of the state shown in FIG. 31 to FIG. 32 takes place almost instantaneously and is stored in the storage tool 14. The plurality of dishes 37 are maintained in a substantially vertical posture.

  In addition, by sequentially injecting the cleaning water from the plurality of nozzles 52, 53, 54, 55 to the substantially central portion of the plate 37 at the interval between the peripheral end portions 37c of the plate 37, sufficient cleaning water enters the interval and is adjacent. The plates 37 are sequentially and reliably separated from each other, and the wash water from the plurality of nozzles 52, 53, 54, 55 is diffused as a collision flow at the interval between the front surface 37a and the back surface 37b of the plate 37, and there is no jet of wash water. A high-speed washing water flow discharged outward from the peripheral end portion 37c side can be formed, and the dirt can be reliably removed.

  FIG. 33A shows a state in which the storage tool 14 is moved by the conveyor 2 with respect to the nozzles 52 and 53 from the state of FIG. 32 and the washing water is hitting the peripheral end portion 37c of the dish 37 positioned second. . The amount of the diversion component of the wash water from the peripheral end portion 37c of the second dish 37 to the first dish 37 side by the movement of the storage tool 14 is changed from the second to the third dish 37 side adjacent to the second dish 37. When it is larger than the amount of the diversion component of the washing water, the rear surface 37b of the dish 37 located at the head and the surface 37a of the dish 37 located second are in a separated state as shown in FIG.

  Furthermore, the amount of the diversion component of the washing water from the peripheral end portion 37c of the second dish 37 to the adjacent third dish 37 side by the movement of the storage tool 14 is the peripheral edge of the second dish 37. When the amount of the diversion component of the washing water from the portion 37c to the top plate 37 is increased, the second plate 37 moves to the top plate 37 as shown in FIG. 33 (b). Then, the plate 37 is in contact with the top plate 37, and at the same time, the second plate 37 and the adjacent third plate 37 are separated from the contacted state.

  As described above, since the ratio of the divided flow rate changes in a very short time due to the movement of the storage tool 14, the state transition from FIG. 33 (a) to FIG. 33 (b) is performed almost instantaneously. The plurality of dishes 37 stored in 14 are maintained in a substantially vertical posture. In the state shown in FIG. 33 (b), the dirt on the surface 37a of the third plate 37 adjacent to the back surface 37b of the second plate 37 is removed by the flow of the washing water. Thereafter, the same operation and action as described above are repeated by the movement of the storage tool 14, and the dishes 37 stored in the storage tool 14 are sequentially washed.

  FIG. 34A shows a cleaning state when the cleaning water from the nozzles 52, 53, 54, 55 is moved to the position of the back surface 37 b of the dish 37 located at the end by the movement of the storage tool 14. The washing water from the nozzles 52 and 53 enters the space (S6) between the back surface 37b of the plate 37 located at the tail and the base plates 16 and 27, and is applied to the surfaces of the base plates 16 and 27 of the storage device 14 and the tail. The collision is repeated between the rear surface 37b of the dish 37 and the dirt on the rear surface 37b of the dish 37 located at the end is removed and washed. The plurality of dishes 37 stored in the storage device 14 are in a vertical posture by pressing the back surface 37b of the dish 37 located at the rearmost end by the washing water.

  In general, there is less dirt on the back side of the dish 37 than on the front side of the dish 37, but the above-described action reliably removes dirt on the back surface 37b of the dish 37 located at the tail. In the cleaning operation shown in FIGS. 31 to 34, the container 14 itself is also cleaned by the flow of the cleaning water sprayed from the nozzles 52, 53, 54, and 55 and the cleaning water from the dish 37.

  In FIG. 34 (b), the cleaning water from the nozzles 52, 53, 54, and 55 is moved to a position where it is removed from the base plates 16 and 27 of the storage tool 14 by the movement of the storage tool 14 from the state of FIG. 34 (a). The cleaning state is shown. At this time, since the washing water from the nozzles 52 and 53 does not hit the plurality of dishes 37, as shown in FIG. 7, the plurality of dishes 37 return to a state inclined at a predetermined angle (θ3) as in the storage. Become.

  As described above, the cleaning operation shown in FIGS. 31 to 34 is performed in the rough cleaning zone 7a, the intermediate cleaning zones 7b and 7c, and the finishing cleaning zone 7d, and the cleaning of the dish 37 stored together with the storage device 14 is completed. The dish 37 that has been cleaned is stored in the storage tool 14 by being dried, sterilized, or the like in the next step. In one cleaning zone, the cleaning operation shown in FIGS. 31 to 34 may be performed a plurality of times by moving the container 14 in one direction, and the cleaning operation is selected as necessary. The tray 51 described in the first embodiment can be cleaned in the same manner.

  In the cleaning operation shown in FIGS. 31 to 34, the cleaning water is sprayed from the nozzles 52 and 53 in the direction crossing each other from the lower half side of the dish 37, and further the upper half of the dish 37 from the nozzles 54 and 55. The cleaning water is jetted in a direction that intersects with each other from the side, but washing is performed by jetting the washing water in the direction intersecting with each other from the lower half side of the dish 37 only from the nozzles 52 and 53. You may do it. In this case, the wash water from the nozzles 52 and 53 enters the space between the peripheral end portions 37 c on the lower side of the dish 37, the adjacent dishes 37 are separated from each other, and the wash water is drained to the upper side of the dish 37. It can be washed by flowing. In order to clean the front surface 37a of the dish 37 located at the head, openings (not shown) are provided in the frames 17 and 28 of the container 14, and the cleaning water from the nozzles 52 and 53 is passed through the openings. What is necessary is just to inject on the surface 37a of the dish 37.

  Further, the dishes 37 adjacent to each other are separated from each other by the washing water from the nozzles 52 and 53, the front surface 37 a and the back surface 37 b of the dish 37 are washed by the flow of washing water, and shower-like washing water is discharged from the nozzles 54 and 55. You may make it inject from the upper side of the plate | plate 37. FIG. In this case, it is possible to prevent the dirt from reattaching to the cleaned dish 37.

  Further, in the above-described cleaning state, the plurality of dishes 37 are changed from the posture inclined at a predetermined angle by the cleaning water to the substantially vertical posture, but the posture inclined at the predetermined angle (θ3) is slightly changed in the vertical direction to be inclined. Alternatively, the plates 37 adjacent to each other may be separated from the contact state to the non-contact state, and the cleaning water may be flowed to perform cleaning. Even in this state, the cleaning water from the nozzles 52 and 53 can be made to flow into the interval between the peripheral end portions 37 c on the lower side of the dish 37 and further to flow upward to the upper side of the dish 37 for cleaning.

  The change angle of the posture of the dish 37 from the posture inclined at a predetermined angle (θ3) to the vertical direction is, for example, the amount of cleaning water from the nozzles 52, 53, the jetting speed, and the movement of the container 14 in the cleaning space 7. Can be adjusted by speed etc. By adjusting at least one of reducing the amount of washing water from the nozzles 52 and 53, slowing the jetting speed, and speeding up the moving speed of the storage tool 14 in the washing space 7 The change angle of the posture in the vertical direction tends to be small, and the spacing between the upper sides of the adjacent tableware is also narrowed. What is necessary is just to set this to optimal conditions with the shape of a tableware, mass, and the grade of dirt.

  The basic cleaning method in the second embodiment can obtain the same operations and effects as those in the first embodiment.

  The basic configuration and the cleaning operation are as described above. As for means for generating different flow trajectories at intervals separated in each cleaning zone, cleaning is performed by spraying from a plurality of nozzles shown in FIGS. What is shown in the water state diagram can be implemented in the same manner particularly for the cleaning water sprayed from the nozzles 52 and 53, and the description thereof will be omitted.

  As described above, according to the tableware cleaning method and the tableware cleaning apparatus of the present invention, it is possible to reliably and efficiently remove the stains of the tableware stored in the storage device in a compact manner without the need for individual support of a plurality of tableware. be able to.

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