Description

The present invention relates to a dish organizing device and a dish cleaning system.

In recent years, with the development of the restaurant industry, automation of kitchen equipment has been advanced (for example, refer to Patent Document 1-2).

Japanese Patent No. 5744778 Japanese Patent No. 5437461

The washing device for washing dishes is a batch-type washing device that puts a container loaded with dishes into the washing tank to perform the washing process, and a washing process for the dishes set in the intake port sequentially. There is a continuous cleaning device that performs. Here, for example, in a store that handles a large number of specific dish dishes, such as a revolving sushi restaurant where dish dishes with various foods and drinks circulate on a conveyor, in order to rationalize the cleaning process of a large number of dish dishes. , A continuous dish-washing device specialized for washing specific dishes is used. Such a dish washing apparatus can wash the specific dish dish at high speed, but cannot wash dish types other than the particular dish dish. Further, it is necessary to correctly set the particular tableware plate in the plate intake.

Therefore, for example, as disclosed in Patent Document 1, regarding a tableware plate in which a conveyor transporting path for carrying out dishware from a water tank is formed along the wall surface of the water tank and placed on the conveyor in a non-regular posture Has proposed a device for stacking dish dishes in a prescribed posture by dropping them in the water tank. However, when the dishware is placed in an unstable state on the conveyor that carries out the dishware from the water tank, the dishware may drop from the conveyor to the water tank while being conveyed along the wall surface of the water tank. Therefore, for example, even if it is placed on the conveyor in a specified posture, or even if it is placed outside the specified posture in a state in which it can be corrected by a mechanism that corrects it, the conveyor is unstable. A large number of dishes and plates that fall from the conveyor on the way because they are placed in a state may occur. When there are many dish dishes placed on the conveyor in such an unstable state, the operation efficiency of the device for stacking dish dishes in a prescribed posture is reduced.

Then, this application makes it a subject to provide the technique which can convey a plate dish efficiently from a water tank by a conveyor.

In order to solve the above problems, in the present invention, while the conveyor surface of the conveyor forming a conveyor path along the wall surface of the tank is unrolled from the aquarium containing the tableware is inclined to the wall surface side, and the dish plate is in the middle of the conveyor path. We decided to provide a protruding part that contacts.

Specifically, it is a dish organizing device for organizing tableware dishes, and a tank placed on a conveyor that forms a conveyance path along the wall of the aquarium and a water tank into which the dish dishes are put or flows, and feeds from below the water surface of the aquarium. A conveyor device that conveys the dishware to a predetermined position, a support portion that supports the conveyor so that the conveyor surface is inclined toward the wall surface, and a portion that is located in the middle of the conveyance path and protrudes from the wall surface. And a protruding portion with which the tableware placed on the table comes into contact.

Here, the predetermined position is a position at which the dish organizing device places the dishes, for example, a dish intake of the dish cleaning device adjacent to the dish organizing device, a carrying tool or a conveyor for carrying the dishes. This is the position where the class is placed. In addition, "along the wall surface of the water tank" is not limited to that along all the wall surfaces of the water tank, and for example, a part or all of the convey path of the conveyor may be along a part of the wall surface of the water tank. .. Further, the starting point of the conveyor means the starting point of the conveying path through which the conveyor conveys the dishes and dishes, and does not mean the position of the roller at the end supporting the conveyor.

In such a dish organizing apparatus, since the convey surface of the conveyor is inclined toward the wall surface, it is difficult for the dishware being conveyed to the conveyor to fall below the water surface of the aquarium. Even if a dish plate is placed on the conveyor surface in an unstable posture, the dish plate comes into contact with the protrusion and is shaken. A stable position can be achieved at an appropriate point on the surface. Therefore, with such a dish organizing apparatus, the transport efficiency when transporting dish dishes from the water tank by the conveyor is improved. Therefore, for example, when the dish reversing mechanism for reversing the inside and outside of the dishware in the upside-down state is combined, it is possible to efficiently align the front and back of the dishware.

It should be noted that stoppers that stop the slide of the dish on the conveyor are discretely fixed to the conveyor surface of the conveyor, and the projecting portion may project from the wall surface at an uphill portion in the transportation path. With such a dish organizing device, the dishware that has been shaken by the contact with the protrusion is caught by the stopper, so that the dishware that was in an unstable state should be placed in a stable position at an appropriate point on the transport surface. You can

The dish organizing device is further provided at a position located on the rear side of the projecting portion in the transport path, and further includes a contact portion for contacting the further stacked dish dishes on the dish dishes placed on the conveyor. It may be one. If such a contact portion is provided, it is possible to prevent the dishes and dishes from being conveyed to a predetermined position in a stacked state.

Further, the above-mentioned dish organizing device is a back tray which is in contact with the back tray in the state of being turned over among the tableware trays conveyed to the conveyor on both sides of the conveyor and is continuously pushed from the rear by the stoppers fixed to the conveyor conveyance surface. The course changing means for changing the course of the tray diagonally upward, and the course of the course changed diagonally upward by the course changing means, and the back tray that is continuously pushed from the rear by the stopper that moves with the conveyor, becomes a support member that supports the front side portion of the back tray. It may further be provided with a dish reversing mechanism having a dish reversing means for riding on and reversing the front and back. If such a dish inverting mechanism is provided, the dish dish in the upside-down state is inverted by the dish inverting means, so that the front and back sides of the dish dish can be efficiently aligned.

The present invention can also be viewed from the side of the dish washing system. For example, the present invention may be a dish cleaning system including the dish organizing device described above and a dish cleaning device in which a dish inlet for taking in dish dishes to be cleaned is arranged at a predetermined position. With the dish washing system configured in this way, dish dishes that are put in or flowing into the water tank are automatically washed. Therefore, when a large number of specific dish dishes are handled, the dish dish washing process is rationalized. It is possible.

With the dish organizing apparatus and the dish washing system according to the present invention, tableware dishes can be efficiently conveyed from the water tank by the conveyor.

Hereinafter, embodiments of the present invention will be described. The embodiment described below is one aspect of the present invention and does not limit the technical scope of the present invention. The following embodiments and modifications are suitable, for example, for restaurants that provide various foods and drinks such as sushi and beverages, soba and udon, and fried chicken and tempura.

FIG. 1 is an external view of a dish washing system 100 according to the embodiment of the present invention. The dish washing system 100 is a system for automatically washing dish dishes 3 on which food and drink is placed, and includes a dish organizing device 1 and a dish washing device 2. The dish organizing device 1 carries out the tableware dishes 3 to be put into the water tank 10 from the water tank 10 by the conveyor device 20, and the dish intake port of the dish cleaning device 2 adjacent to the dish organizing device 1 (referred to as “predetermined in the present application”. 210) (which is an example of a position). The dish washing device 2 is provided with an optical sensor for detecting whether or not the dish dishes 3 stacked in the dish intake port 210 have reached a predetermined height. When the optical sensor detects that the plate has reached a predetermined height, it automatically cleans the dishes 3 stacked on the plate intake 210 and pays them out to the plate outlet 220.

The water level of the water tank 10 is maintained at a specified water level or higher by a solenoid valve that automatically opens and closes by receiving a signal from a water level sensor that detects a decrease in the water level. The solenoid valve may be opened and closed regularly regardless of the signal from the water level sensor to exchange water according to the hygiene condition required for the dish arrangement device 1. The water supply to the water tank 10 also has a function of cleaning the sprockets provided on the conveyor device 20 and the guides of the conveyor, and water supply nozzles from which the water supply blows are provided at appropriate places (for example, four places) inside the conveyor device 20. At the time of water supply, the detergent may be automatically supplied in conjunction with the water supply. The detergent may be supplied in the form of flowing down from a detergent supply nozzle provided in the water tank 10, or may be supplied in the form of mixing the detergent with the supply water by a mixer provided in the middle of the water supply pipe. May be.

Further, the depth of the dish organizing apparatus 1 is substantially the same as the depth of the dish cleaning apparatus 2, and as shown in FIG. 1, the front surface of the dish organizing apparatus 1 is flush with the front surface of the dish cleaning apparatus 2. The dishwashing system 100 can be configured to be located.

FIG. 2 is a perspective view showing a main part of the dish organizing apparatus 1. The dish organizing device 1 forms a transport path along the wall 10 of the water tank 10 into which the dish tray 3 is loaded, and the dish tray 3 is placed on the conveyor 21 that is fed from below the water surface of the water tank 10. The conveyor device 20 that conveys toward the mouth 210. Further, the dish organizing apparatus 1 includes water discharge ports 31 and 32 for flowing the dish dishes 3 of the water tank 10 to the starting point S of the conveyor 21 in the water tank 10, and the turntable 12. Further, the dish organizing device 1 includes a detergent supply port 34 for supplying a detergent into the water tank 10 on the wall surface in the water tank 10. Further, the plate arranging device 1 includes a plate inverting device 90 near the end point E of the conveyor 21. The vicinity of the end point E of the conveyor 21 is a concept including not only the end point E of the conveyor 21 but also the periphery of the end point E of the conveyor 21.

The water tank 10 is an water tank whose upper side is open and in which a horizontally long tank interior is formed by the wall surface 11. Further, the bottom surface of the water tank 10 is formed by a circular rotating disk 12 and a flat plate around the disk. A bar-shaped dish pushing member 13 is provided on the surface of the turntable 12. The plate pushing member 13 extends toward the peripheral edge of the rotary disc 12 from a position slightly away from the center of rotation of the rotary disc 12. Therefore, when the turntable 12 rotates, the tableware dish 3 pushed by the dish pushing member 13 is pushed not in the tangential direction of the turntable 12 but in the centrifugal direction rather than the tangential direction. Therefore, even when the dishware 3 is placed in the water tank 10, it is possible to spread the loaded dishware 3 in the centrifugal direction and efficiently disassemble it. Further, the water tank 10 is provided with a suction port for flowing the water in the tank to the water circulation device. Then, the water in the water tank 10 sucked from the suction port is pressurized by the water circulation device and flows into the water tank 10 again from the discharge ports 31 and 32. Therefore, the dishware 3 floating in the water tank 10 is swept away by the water flow flowing out from the discharge ports 31 and 32.

The conveyor device 20 forms a conveyance path that circulates in the water tank 10 along the wall surface 11 of the water tank 10, and includes a conveyor 21 that extends from below the water surface of the water tank 10, and a conveyor drive mechanism 22 that drives the conveyor 21. By driving the conveyor 21 by the conveyor drive mechanism 22, the conveyor 21 is paid out from under the water surface of the water tank 10, and the plate 3 of the water tank 10 placed on the conveyor 21 is conveyed from the start point S to the end point E. At the end point E of the conveyor 21, there is provided a plate guide mechanism that guides the tableware dishes 3 placed on the conveyor 21 to the plate intake port 210 of the dish cleaning device 2 and stacks them on the plate intake port 210.

The conveyor 21 has an upper guide 24U that guides the feed portion from the start point S to the end point E so as to move along a curve or a straight line, and a return portion from the end point E to S on the lower side of the transport path. Is supported by a lower guide 24L that guides the return portion so as to move along a curved line or a straight line.

Then, in the dish organizing device 1, the three projecting members 14 that come into contact with the tableware dishes 3 placed on the conveyor 21 are located at the midpoint of the upslope of the transport path formed by the conveyor 21 at the wall surface 11 of the water tank 10. It is provided so as to project from the wall surface of the. Further, in the plate organizing apparatus 1, a contact member 15 is provided at a position located on the rear side of the projecting member 14 in the transport path formed by the conveyor 21. The contact member 15 is a member with which the tableware dishes 3 further stacked on the tableware dishes 3 placed on the conveyor 21 come into contact.

FIG. 3 is a top view showing a main part of the dish organizing apparatus 1. The starting point S of the conveyor 21 is sunk below the water surface indicated by the shaded area in FIG. Further, the water suction port 33 covered with a resin plate material formed into a punching metal shape by a plurality of holes is provided near the starting point S of the conveyor 21, as shown in FIG. Therefore, the water discharged from the discharge ports 31 and 32 flows through the dishware 3 toward the starting point S side of the conveyor 21, and then is sucked into the suction port 33 and pressurized by the water circulation device, and the discharge ports 31 and 32 are again discharged. Is discharged from.

FIG. 4 is a front view showing a main part of the dish organizing apparatus 1. The arrow shown in the vicinity of the conveyor 21 in FIG. 4 indicates the operation direction when the conveyor 21 is rotating normally. In FIG. 4, for convenience of illustration, a part of the conveyor 21 is shown by a chain double-dashed line.

As shown in FIG. 4, the conveyor 21 is fed from below the water surface of the water tank 10 to form an ascending conveyance path, and conveys the plate 3 in the water tank 10 from the start point S to the end point E. . Then, the conveyor 21 turns back at the end point E, travels in the opposite direction on the lower side of the transport path, and follows the route that returns to the start point S again. That is, the conveyor 21 is a conveyor in which an endless chain circulates, is moved by sprockets provided at the start point S and the end point E, and is appropriately moved by a tensioner provided at an intermediate point between the start point S and the end point E. Tension is applied. The upper guide 24U and the lower guide 24L that guide the movement of the conveyor 21 have a smaller surface friction coefficient than stainless steel, and are formed of resin that allows the conveyor 21 to slide easily.

Then, the conveyor 21 temporarily reverses the conveyance direction by reversing the rotation direction of the conveyor drive mechanism 22 when, for example, the increase in the load applied to the conveyor 21 due to the contact of the dish plate 3 with the contact member 15 is automatically detected. It is possible to reverse. Even when the dish plate 3 contacts the contact member 15, if the conveying direction of the conveyor 21 is temporarily reversed, the attitude of the dish plate 3 contacting the contact member 15 is corrected, and the like. In some cases, the dish plate 3 can be made to pass through the contact member 15. If the dishware 3 in contact with the contact member 15 is automatically allowed to pass through the contact member 15, the burden on the operator who handles the dish organizing apparatus 1 can be reduced.

As shown in FIG. 4, the dish organizing device 1 is provided with a rotary disc drive device 40 for rotating the rotary disc 12 below the water tank 10, and a shaft sealing device provided below the water tank 10. The rotary shaft of the rotary disk 12 is rotated by the rotational power transmitted via the rotary shaft of the rotary disk 12 inserted into the.

Further, as shown in FIG. 4, stoppers 23 capable of hooking the plate 3 are discretely fixed at predetermined intervals on the conveying surface of the conveyor 21. Between the stoppers 23, there is an interval in which only one plate 3 is fitted. Here, the interval in which only one plate 3 is fitted refers to an interval that is approximately the same as the diameter of the circle that forms the outer edge of the plate 3 or that is slightly wider than the diameter. Therefore, when the tableware dishes 3 are fitted between the stoppers 23, the tableware dishes 3 are arranged at equal intervals on the transport surface of the conveyor 21.

FIG. 5 is a diagram showing an example of the movement of the plate 3 in the water tank 10. The thick arrow shown in FIG. 5 indicates the direction of the water flow flowing from the discharge port 31 and the discharge port 32.

The discharge port 31 is provided on the left side (the left side on the paper surface of FIG. 5) which is one end side in the longitudinal direction in the horizontally long tank, and discharges water toward the right side. Further, the discharge port 32 is provided on the back side (upper side in the plane of FIG. 5) which is one end side in the lateral direction in the horizontally long tank, and water is directed toward the front side where the starting point S of the conveyor 21 is located. Discharge. Therefore, the water flow flowing out from the discharge port 31 flows toward the right side. Further, the water flow flowing out from the discharge port 32 flows toward the front side. That is, the discharge port 32 discharges water in a direction different from the direction of the water flow flowing out from the discharge port 31.

When the tableware dishes 3 are put into such a water tank 10 and the tableware dishes 3 are stacked on the turntable 12, the submerged dishware 3 flow out from the rotating force of the turntable 12 and the discharge port 31 and the discharge port 32. Receive the force of water flow. Therefore, as shown in FIG. 5(A), the tableware dishes 3 initially stacked in the water tank 10 receive the rotational force of the turntable 12 and the force of the water flow flowing out from the discharge port 31 and the discharge port 32. Move gradually. Further, the water flow flowing out from the discharge port 31 shakes the dish plates 3 which are overlapped intricately at the start point S and its periphery, thereby eliminating the stacking state of the overlapped dish plates 3. Then, the plate 3 gradually approaches the starting point S of the conveyor 21, as shown in FIG. 5(B). Then, when the dish plate 3 reaches the starting point S of the conveyor 21, it is placed on the conveyor surface of the conveyor 21 as shown in FIG. 5C and is conveyed along the conveyance path of the conveyor 21. Then, the dishware 3 placed on the transport surface of the conveyor 21 moves from the starting point S toward the ending point E, as shown in FIG.

The rotation of the turntable 12 and the water flow flowing from the discharge port 31 and the discharge port 32 are appropriately controlled according to the rotation torque detected by the turntable driving device 40 that rotates the turntable 12. For example, when the rotary disk drive device 40 that rotates the rotary disk 12 detects a rotational torque of about 60% of the rated value, the rotary disk drive device 40 is temporarily stopped, and the discharge port 31 and the discharge port 32 are used. Increase the flow of water flowing. Since such an operation is automatically realized by the control device, even if a large amount of tableware 3 is put into the water tank 10, the turntable driving device 40 is not overloaded and is piled up on the turntable 12. The dish plate 3 collapses due to the water flow and moves toward the starting point S.

By the way, as described above, the protruding member 14 is provided in the middle of the conveying path formed by the conveyor 21. Therefore, the tableware 3 placed on the conveyor 21 moves as follows while being conveyed to the conveyor 21.

FIG. 6 is a diagram showing the movement of the dish tray 3 at the location where the protruding member 14 is provided. In the plate organizing apparatus 1 shown on the lower side of FIG. 6, the state of the tableware plate 3 at the portion indicated by the round letter “A”, that is, the portion where the protruding member 14 is not provided is indicated by the upper left enclosure line in FIG. 6. It is illustrated in the column shown. Further, in the dish organizing apparatus 1 shown on the lower side of FIG. 6, the state of the dish tray 3 at the portion indicated by the circled letter “B”, that is, the portion where the protruding member 14 is provided, is shown in the upper right of FIG. It is illustrated in the column indicated by a line.

As can be seen from FIG. 6, the conveyor 21 is supported by the upper guide 24U so that the conveying surface is inclined toward the wall surface 11 side. The inclination angle is such an angle that the dishware 3 placed on the conveying surface of the conveyor 21 is closer to the wall surface 11 side, for example, in the range of 1 to 45 degrees with respect to the horizontal plane, and more preferably in the range of 5 to 20 degrees. Within. This inclination may be formed in the entire area of the conveyor 21 from the starting point S to the ending point E, or may be formed in a specific area. Since the conveying surface of the conveyor 21 is inclined to the wall surface 11 side, while the conveyor 21 conveys the dish plate 3, the dish plate 3 moves along the conveying path while approaching and contacting the wall face 11. Therefore, when passing through the place where the projecting member 14 is provided, the dish plate 3 contacts the projecting member 14 as illustrated in the column indicated by the encircling line in the upper right of FIG. 6. Therefore, in the dish organizing apparatus 1, for example, the dish tray 3 may move as follows.

FIG. 7 is a diagram showing an example of the movement of the dishware 3 in contact with the protruding member 14. Of the tableware dishes 3 placed on the conveying surface of the conveyer 21, the tableware dish 3 having the front surface facing upward is denoted by reference numeral 3S, and the dishware plate 3 (back tray) having the back surface facing upward is denoted by reference numeral 3S. 3U, and the plate 3 further stacked on the other plate 3 is indicated by reference numeral 3K.

As shown in FIG. 7, the dishware 3 placed on the conveyor surface of the conveyor 21 is conveyed while being caught by the stopper 23 fixed to the conveyor surface of the conveyor 21. However, depending on the state in which it is placed on the transport surface of the conveyor 21 at the start point S, for example, as shown in FIG. 7A, the dish dishes 3K may be stacked on the dish dish 3S. However, in the dish organizing apparatus 1 of the present embodiment, since the tableware dishes 3 being conveyed to the conveyor 21 come into contact with the projecting members 14 during the course of conveyance, the dishware plates 3K stacked on the tableware dishes 3S are also projecting members 14. Swayed by the touch of. The tableware plate 3K swayed by the contact with the projecting member 14 slides on the tableware plate 3S while touching the wall surface of the wall surface 11 as shown in FIG. 7B due to the inclination of the conveying surface of the conveyor 21. Moving. Then, as shown in FIG. 7C, the tableware plate 3K is caught by the stoppers 23 at appropriate places fixed to the conveyor surface of the conveyor 21 and stably rests on the conveyor surface of the conveyor 21. In FIG. 7C, the tableware plate 3K is illustrated with the back side facing upward and placed on the transport surface, and therefore the code 3U is also added to the code of the tableware plate 3K. The tableware dishes 3K and 3S caught on the stopper 23 are fixed by being sandwiched between the stoppers 23 due to the bending of the chain forming the conveyor 21 at the curved portion in the middle from the start point S to the end point E. Therefore, it is conveyed in a stable state even on the slope.

Further, as described above, the contact member 15 is provided behind the projecting member 14 in the middle of the conveying path formed by the conveyor 21. Therefore, the tableware 3 placed on the conveyor 21 moves as follows while being conveyed to the conveyor 21.

FIG. 8 is a diagram showing the movement of the dish tray 3 at the location where the contact member 15 is provided. The contact member 15 has a gap between the conveying surface of the conveyor 21 and the lower end of the contact member 15 that is larger than the thickness of one plate 3 and smaller than the thickness of two plate 3. It is fixed on the transport surface in the state. Therefore, in the place where the contact member 15 is provided, the plate dishes 3 can pass through one by one, and the plate dishes 3K stacked on the plate 3S and the plate 3U come into contact with the contact member 15 and pass through. Can not do it. Therefore, for example, when the dish plate 3K overlaps the dish plate 3S as shown in FIG. 8A, the dish plate 3K contacts the contact member 15 as shown in FIG. 8B. To do. The dish plate 3K contacting the contact member 15 moves on the dish plate 3S while sliding on the dish plate 3S as shown in FIG. 8B due to the inclination of the conveying surface of the conveyor 21. Then, as shown in FIG. 8C, the dish plate 3K is caught by the stoppers 23 at appropriate positions fixed to the conveyor surface of the conveyor 21, and is stably placed on the conveyor surface of the conveyor 21. In FIG. 8(C), the tableware plate 3K is illustrated with the back side facing upward and placed on the transport surface, and therefore the code 3U is also added to the code of the tableware plate 3K.

The conveyor 21 reverses the rotation direction of the conveyor drive mechanism 22 when, for example, the increase in the load applied to the conveyor 21 due to the contact of the tableware 3 with the contact member 15 is automatically detected. Therefore, for example, even when two or more tableware dishes 3 are sandwiched between the contact member 15 and the conveyor 21, the conveying direction of the conveyor 21 is temporarily reversed, so that the contact member 15 and The dishware 3 sandwiched between the conveyor 21 and the conveyor 21 descends on an inclined slope. Then, the dishware 3 having an unstable posture moves on the transport surface and is caught by the stopper 23 at an appropriate position on the transport surface to stop. Therefore, the dish organizing device 1 does not bother a worker who handles the dish organizing device 1 even if the dishware 3 is sandwiched between the contact member 15 and the conveyor 21.

FIG. 9 is a diagram showing the effect of the protruding member 14 and the contact member 15. Since the protruding member 14 and the contact member 15 are provided in the middle of the conveyance path formed by the conveyor 21, even if there is a tableware plate 3K stacked on another tableware plate 3, the tableware plate 3K is The tableware plate 3K moves on the conveyor surface of the conveyor 21 while sliding on the tableware plates 3S and 3U stably placed on the conveyor surface of the conveyor 21 without dropping below the water surface of the aquarium 10. Therefore, for example, as shown in FIG. 9, when there are some empty spaces in which the dish 3 fits between the adjacent stoppers 23, the dish 3K moved by the projecting member 14 or the contact member 15 Fits in the empty space. That is, as shown in FIG. 9(A), when there are some empty spaces in which the dish 3 fits between the adjacent stoppers 23, the dish 3K contacts the protruding member 14 and the contact member 15. Then, as shown in FIG. 9B, the dish plate 3K moves toward the empty space. Therefore, when the tableware plate 3K is caught by the stopper 23 beside the empty space, the tableware plate 3K fits in the empty space as shown in FIG. 9C. Therefore, in the dish organizing apparatus 1 of the present embodiment, the transport efficiency is higher than that in the case where the protruding member 14 and the contact member 15 are omitted. Since the plate arranging device 1 of the present embodiment is provided with the plate reversing device 90, not only the tableware plate 3S having the front surface facing upward, but also the tableware plate having the back surface facing upward is provided on the conveying surface of the conveyor 21. Even if a large number of 3Us are mounted, these dish dishes 3 can be stacked in the dish intake port 210 of the dish cleaning device 2 with all surfaces facing upward.

Here, the plate reversing device 90 will be described. FIG. 10 is an example of an enlarged view of the dish reversing device 90. The plate reversing device 90 is provided at the end point E of the conveyor 21. Then, as shown in FIG. 10, the dish reversing device 90 includes a course changing section 91 and a dish reversing section 94, and reverses the front and back sides of the dish plate 3 with the back side facing upward. The path changing unit 91 brings the dishware 3 in an inverted state being conveyed to the conveyor 21 into contact with the two path changing members 92 on both sides of the conveyor 21, and the stopper 23 fixed to the conveying surface of the conveyor 21 from the rear side. The course of the tableware plate 3 which is continuously pressed is changed obliquely upward. Further, the dish reversing unit 94 has two supporting members for supporting the front side portion of the dish plate 3U with respect to the dish plate 3 whose course is changed obliquely upward by the route changing unit 91 and which is continuously pushed from behind by the stopper 23 that moves together with the conveyor 21. Get on 95 and flip the inside out.

If the dish plate 3 that enters the dish reversing device 90 is, for example, a dish plate 3S with its surface facing upward, the course of the dish plate 3S is changed as shown in FIGS. 10(B) and 10(C). Does not contact the part 91. Therefore, the plate 3S passes through the plate reversing device 90 as it is.

FIG. 11 is a diagram showing a state in which the dishware 3S with its surface facing upward passes through the dish inverting device 90. As shown in FIG. 11A, when the plate 3S enters the plate reversing device 90, the plate 3S approaches the course changing unit 91. However, the path changing member 92 of the path changing unit 91 does not contact the edge of the dish plate 3S whose surface is facing upward. Therefore, the dish plate 3S passes by the side of the course changing unit 91 as it is, as shown in FIG. Then, the tableware dish 3S is slid down toward the dish washing device 2 on the dish guiding rail (not shown) that is inclined toward the dish washing device 2 side without changing the posture in the dish reversing device 90. As a result, the dish dishes 3 move to the dish intake port 210 of the dish cleaning device 2 and are stacked on the dish intake port 210 with the surface thereof facing upward.

FIG. 12 is a diagram showing a state in which the dish plate 3U having the back surface facing upward passes through the plate reversing device 90. As shown in FIG. 12A, when the plate 3U enters the plate reversing device 90, the plate 3U approaches the course changing unit 91. Then, the edge of the dish plate 3U contacts the course changing member 92 of the course changing section 91, and the course is changed obliquely upward as shown in FIG. 12(B). Even after contacting the course changing member 92, the dish plate 3U continues to be pushed from the rear by the stopper 23 fixed to the conveying surface of the conveyor 21, and thus moves while sliding on the course changing surface 93. Then, as shown in FIG. 12C, the front side portion of the dish plate 3U starts to be placed on the support member 95 in the process of passing the course changing surface 93, as shown in FIG. 12C. After passing through the course changing surface 93, the tableware plate 3U is in a state in which the front side portion of the tableware plate 3U is supported by the support member 95 from the lower side, but as shown in FIG. The support for the course changing member 92 is lost because it has passed through the changing surface 93. Then, the tableware plate 3U continues to be pushed from the rear by the stopper 23 even after passing through the course changing surface 93, while the support member 95 remains at the same position, so as shown in FIG. The front portion of the dish 3U rides on the support member 95. The tableware plate 3U whose front portion has climbed up on the support member 95 is continuously pushed by the stopper 23, so that a force in a direction for reversing the positional relationship between the front part and the rear part of the tableware plate 3U is applied to the tableware plate 3U. As a result, as shown in FIG. 12(F), the front and back of the plate 3U are inverted. In the dish inverting device 90, the front and back sides of the dish dish 3U are turned upside down, and then the dish dish 3U is slid down toward the dish washing device 2 on a dish guide rail (not shown) that is inclined toward the dish washing device 2 side. .. As a result, the dish dishes 3U are moved to the dish intake port 210 of the dish cleaning device 2 and are stacked on the dish intake port 210 with the surface thereof facing upward.

If the dish cleaning system 100 is configured by combining the dish organizing device 1 having such a dish reversing device 90 with the dish cleaning device 2, the dish intake port 210 of the dish cleaning device 2 is made uniform in the direction of the dishes 3. Even if the dish dishes 3 are not stacked, the dish dishes 3 can be automatically stacked in the dish intake port 210 of the dish cleaning device 2 with the surface of the dish dish 3 facing upward. . Therefore, the number of steps required to stack the dishes 3 can be reduced.

In addition, in the dish organizing apparatus 1 described above, since the conveyor 21 has the conveying surface inclined toward the wall surface 11 side, it is difficult for the dishware 3 conveyed by the conveyor 21 to fall below the water surface of the water tank 10. Therefore, even if the dishware 3 placed on the transport surface of the conveyor 21 in an unstable posture is generated, it is unlikely to drop below the water surface of the water tank 10. Therefore, the operation efficiency of the conveyor 21 is higher than that of the conventional machine in which the conveying surface of the conveyor 21 is not inclined to the wall surface 11 side.

Further, with respect to the dishware 3 conveyed to the conveyor 21 in a state where a plurality of sheets are overlapped with each other, the empty space is left in the conveyor 21 because it fits in the empty space between the stoppers 23 in the middle of the transportation path of the conveyor 21. The probability of moving in the state is low. Therefore, with the dish cleaning system 100 using the dish organizing apparatus 1 described above, it is possible to stack the dish dishes 3 placed in the water tank 10 in the dish intake port 210 very efficiently.

In addition, in the above dish organizing apparatus 1, the tableware dishes 3 are gathered at the starting point S of the conveyor 21 by the two discharge ports 31 and 32 and the turntable 12. For example, when the size of the inside of the water tank 10 is substantially the same in the front-back direction and the left-right direction because the inside of the water tank 10 has a substantially circular shape in a top view, Even if only one of the outlets 32 is provided, it is possible to generate a circulating flow such that the dishware 3 goes around the inside of the water tank 10 and bring the dishware 3 to the starting point S of the conveyor 21. However, when the inside of the water tank 10 is horizontally long as in the dish organizing apparatus 1 described above, if either one of the discharge port 31 and the discharge port 32 is omitted, the inside of the tank of the water tank 10 will be omitted. Since the water flow is stagnant at the left and right ends, it is difficult for the dish plate 3 to rotate in the tank. In this respect, since the above-mentioned dish organizing apparatus 1 is provided with both the discharge port 31 and the discharge port 32, the dish plate 3 becomes the starting point S of the conveyor 21 even though the tank is a horizontally long water tank 10. Stop by. Therefore, the dishware 3 in the tank of the water tank 10 can be efficiently placed on the conveying surface of the conveyor 21. Therefore, in the dish organizing apparatus 1 described above, it is difficult to realize the case where any one of the ejection port 31 and the ejection port 32 is omitted. By making it substantially the same as the depth of 2, it is possible to configure the dish cleaning system 100 in such a form that the front surface of the dish organizing apparatus 1 is located on the same plane as the front surface of the dish cleaning apparatus 2.

In addition, in the above dish organizing apparatus 1, since the tableware dish 3 in the tank of the water tank 10 can be accommodated in the space below the transport path formed by the conveyor 21, more space is provided in the tank of the water tank 10. It is possible to put the tableware 3 of. Such a structure applies tension to the conveyor 21 and supports the conveyor 21 with the upper guide 24U and the lower guide 24L, so that the returning portion of the conveyor 21 from the end point E to the start point S is directed to the water surface in the tank. It is feasible because it has a structure that does not sag.

The dish organizing device 1 is not limited to the usage mode in which the dish dishes 3 are stacked on the dish intake port 210 of the dish cleaning device 2. The dish organizing apparatus 1 may stack the dish dishes 3 on, for example, a transportation tool for carrying the dish dishes 3. Further, the dish organizing device 1 is not limited to the usage mode in which the dish dishes 3 are stacked. For example, the dish organizing apparatus 1 may place the dish dishes 3 taken out of the water tank 10 on a conveyor for transporting the washed dish dishes 3 on which the sushi chef holds the sushi.

Further, the water tank of the dish organizing apparatus 1 is not limited to the horizontally long shape. The water tank of the dish organizing apparatus 1 may have any shape such as a cylinder, a rectangular parallelepiped, a cube, a polyhedron, or the like. In this case, the conveyor of the dish organizing apparatus 1 may appropriately form a transport path according to such various types of water tanks.

Further, the water tank of the dish organizing device 1 is not limited to the one in which the dish tray 3 is placed. The water tank of the dish organizing apparatus 1 forms, for example, a part of a circulation water channel for transporting tableware by water circulating through each table in the restaurant, and the tableware may flow into the water tank. In this case, a collecting member or the like may be provided to prevent the tableware flowing into the water tank from flowing out to the downstream side of the water tank so that the tableware flowing into the water tank gathers at the starting point of the conveyor.

Further, in the plate organizing device 1, the conveyor 21 basically forms the conveying path so as to draw a substantially circumferential direction of the right rotation in a top view, but the respective parts constituting the plate organizing device 1 are configured so that the left and right sides are reversed. It may have been done.
