Description

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

In recent years, along with the development of the restaurant industry, the automation of kitchen equipment is progressing (see Patent Document 1, for example).

Japanese Patent No. 5744778 Japanese Patent No. 5437461

The washing equipment for washing tableware consists of a batch-type washing equipment in which containers loaded with dishes are put into the washing tank and the washing process is executed, and the washing process of the dishes set in the inlet is performed sequentially. There are continuous cleaning systems that run. Here, for example, in a store that handles a large number of specific dishes, such as a conveyor belt sushi restaurant where dishes with various food and drinks circulate on a conveyor, it is necessary to streamline the washing process of a large number of dishes. , continuous dishwashing equipment specialized for washing specific dishware is utilized. Such a dish washing apparatus can wash a specific dish plate at high speed, but cannot wash dishes other than the specific dish plate. Also, it is necessary to properly set the particular dish in the dish intake.

Therefore, for example, as disclosed in Patent Document 1, the conveying path of the conveyor for carrying out the dishes from the water tank is formed along the wall surface of the water tank, and the dishes placed on the conveyor in an unregulated posture has proposed a device for stacking dish plates in a prescribed posture by dropping them into the water tank. However, in such an apparatus, in order to place the dishes in the tank on the conveyor, it is necessary to move the dishes in the tank to the starting point of the conveying path formed by the conveyor.

Here, for example, when the tank is square or circular in top view, and the size of the tank is approximately the same in the front-back direction and the left-right direction, a circulating flow is generated so that the dish plate rotates inside the tank. It is possible to move the tableware plate to the starting point of the conveying path simply by However, for example, when the size of the tank is different between the front-rear direction and the left-right direction because the tank is rectangular when viewed from above, even if a circulating flow is generated so that the dish plate rotates inside the tank, Since the water flow is stagnant at the ends of the tub in the longitudinal direction, there is a possibility that the movement of the dish plate will be stagnated within the tub. Therefore, in such a water tank, it is difficult for the dishes in the water tank to be placed on the conveyer drawn out from under the water surface of the water tank.

Therefore, the object of the present application is to provide a technique capable of smoothly placing dish plates on the conveyor in the tank when the dish plates are placed on the conveyor drawn out from under the water surface of the water tank and conveyed.

In order to solve the above problems, in the present invention, in addition to a first water flow generating means for discharging water in a first direction in a tank of a water tank, a water flow generating means for discharging water in a second direction different from the first direction is provided. A second water flow generating means for discharging water is provided.

More specifically, the present invention is a dish arrangement device for arranging dishes, which includes a water tank into which dishes are thrown or flowed, and a conveyor that forms a conveying path along the wall surface of the water tank and feeds out from under the water surface of the water tank. a conveyer device for conveying the dish plates placed on the plate in the tank to a predetermined position; Rotating means for rotating a circular rotating disk forming a bottom surface, a first water flow generating means for discharging water in a first direction in the tank, and a direction different from the first direction in the tank and a second water flow generating means for discharging water in a second direction.

Here, the predetermined position is the position where the plate arrangement device places the dishes. The position where the class is placed. Further, "along the wall surface of the water tank" is not limited to "along the entire wall surface of the water tank". . Also, the starting point of the conveyor means the starting point of the conveying path along which the conveyor conveys the dishes, and does not mean the position of the end rollers that support the conveyor.

With such a dish arrangement device, water currents flowing in at least two directions are generated in the tank of the water tank. Therefore, even if the size of the inside of the tank is different in the front-rear direction and the left-right direction, even if the water tank has a configuration in which a single water flow generating means cannot be expected to generate a circulating flow that circulates inside the tank, The water currents flowing in two or more directions can suppress the stagnation of the water currents in the tank, and can minimize the possibility that the movement of the dish plate is stagnant in the tank.

The water tank has different sizes in the front-rear direction and the left-right direction. , the first water flow generating means discharges water from the other end side in the longitudinal direction of the tank toward one end side, and the second water flow generating means conveys water from the one end side in the lateral direction of the tank. It may be one that discharges water toward the starting point of the path. If such a water flow generating means is provided, it becomes possible to move the dishes in the tank toward the starting point of the transport path.

In addition, the inside of the tank is formed to be horizontally long, and the conveyor device forms the transfer route so that the starting point of the transfer route is on the right side of the tank, and the transfer route is drawn so as to draw a substantially circular circumference that rotates clockwise when viewed from the top. The first water flow generating means may discharge water toward the right side of the water tank, and the second water flow generating means may discharge water toward the front side of the water tank. If such a water flow generating means is provided, it becomes possible to move the dishes in the tank to the right side where the starting point of the transport path is located.

Further, the dish flow means may increase the amount of water discharged by the first water flow generating means and the second water flow generating means when detecting an increase in the load applied to the rotating disk. If such control is carried out, it is possible to prevent overloading of the rotating means, and to automatically move the dishes piled up on the turntable toward the starting point of the conveying route by breaking them down with the water flow. can be moved flexibly.

The present invention can also be viewed in terms of dishwashing systems. For example, the present invention may be a dish washing system comprising the above-described dish organizing apparatus and a dish washing apparatus in which a dish inlet for taking in dishes to be washed is arranged at a predetermined position. With the dish washing system configured in this manner, the dishes that are thrown into or flowed into the water tank are automatically washed, so that when a large number of specific dishes are handled, the washing process for the dishes can be streamlined. It is possible.

With the dish arrangement apparatus and the dish washing system according to the present invention, when the dishes are placed on the conveyor drawn out from under the water surface of the water tank and conveyed, the dishes can be smoothly placed on the conveyor in the tank.

Each of the embodiments and modifications described below is suitable for, for example, restaurants serving various food and drink such as sushi, beverages, rice bowls such as soba and udon, fried chicken and tempura.

FIG. 1 is an external view of a dish washing system 100 according to an embodiment of the present invention. A dish washing system 100 is a system for automatically washing dishes 3 on which food and drink are placed, and includes a dish arrangement device 1 and a dish washing device 2 . The dish arrangement device 1 carries out the dish plates 3 to be put into the water tank 10 from the inside of the water tank 10 by the conveyor device 20, and the plate intake port of the dish washing device 2 adjacent to the dish arrangement device 1 (referred to as "predetermined 210, which is an example of "position". The dish washing device 2 is provided with an optical sensor for detecting whether or not the dish plates 3 stacked in the dish intake port 210 have reached a predetermined height. When it is detected by the optical sensor that the predetermined height has been reached, the tableware plates 3 piled up in the plate intake port 210 are automatically washed and delivered to the plate delivery port 220.例文帳に追加

The water level of the water tank 10 is kept above a specified water level by an electromagnetic valve that automatically supplies water by opening and closing in response to a signal from a water level sensor that detects a drop in the water level. The electromagnetic valve may be periodically opened and closed regardless of the signal from the water level sensor, so that water can be exchanged according to the sanitary conditions required for the dish arrangement device 1 . The water supply from the water tank 10 also functions to clean the sprockets and conveyor guides provided in the conveyor device 20, and water supply nozzles from which water is blown out are provided at appropriate locations (for example, four locations) within the conveyor device 20. At the time of water supply, detergent may be automatically supplied in conjunction with 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 water supply in a mixer provided in the middle of the water supply pipe. may

Further, the depth of the dish cleaning device 1 is substantially the same as the depth of the dish cleaning device 2, and as shown in FIG. The dishwashing system 100 can be configured to locate.

FIG. 2 is a perspective view showing a main part of the plate arrangement device 1. As shown in FIG. The dish arrangement device 1 forms a conveying path along a water tank 10 into which the dish plates 3 are put and a wall surface 11 of the water tank 10, and places the dish plates 3 on a conveyer 21 drawn out from under the water surface of the water tank 10 to take in the dishes. and a conveyor device 20 for conveying toward the mouth 210 . The plate arrangement device 1 also includes water outlets 31 and 32 for causing the dish plates 3 in the water tank 10 to flow to the starting point S of the conveyor 21 in the water tank 10, and a rotating disk 12. As shown in FIG. Further, the dish arrangement device 1 includes a detergent supply port 34 for supplying detergent into the water tank 10 on the wall surface inside the water tank 10 . The plate arrangement device 1 also has a plate reversing 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 surroundings of the end point E of the conveyor 21 .

The water tank 10 is a water tank whose upper side is open and a laterally long tank interior is formed by a 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 it. A rod-shaped plate pressing member 13 is provided on the surface of the rotating disk 12 . The plate pressing member 13 extends toward the periphery of the rotary disc 12 from a position slightly away from the center of rotation of the rotary disc 12 . Therefore, the dish plate 3 pushed by the plate pushing member 13 is pushed not only in the tangential direction of the rotary disc 12 but also slightly in the centrifugal direction rather than in the tangential direction when the rotary disc 12 rotates. Therefore, even when the tableware plate 3 is loaded in the water tank 10, the loaded tableware plate 3 can be spread out in the centrifugal direction and can be efficiently dismantled. 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 again into the water tank 10 from the discharge ports 31 and 32 . Therefore, the dish plate 3 floating in the water tank 10 is swept away by the water currents flowing out from the outlets 31 and 32 .

The conveyor device 20 forms a conveying path that circulates inside the water tank 10 along the wall surface 11 of the water tank 10, and includes a conveyor 21 that feeds out from under the water surface of the water tank 10, and a conveyor driving mechanism 22 that drives the conveyor 21. A conveyor driving mechanism 22 drives the conveyor 21 to let out the conveyor 21 from under the water surface of the water tank 10, and the dish 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, a dish guide mechanism is provided for guiding the dishes 3 placed on the conveyor 21 to the dish inlet 210 of the dish washing apparatus 2 and stacking them on the dish inlet 210. As shown in FIG.

Conveyor 21 has an upper guide 24U that guides the feeding portion from start point S to end point E so that it moves along a curved line or a straight line, and a return portion from end point E to S on the lower side of the conveying path. and lower guides 24L that guide the return portion to move along curves and straight lines.

In the plate arrangement device 1, the three protruding members 14 contacting the dish plates 3 placed on the conveyor 21 are arranged on the wall surface 11 of the water tank 10 at a portion located in the middle of the ascending slope of the conveying path formed by the conveyor 21. is provided in a state of protruding from the wall surface of the Further, the plate arrangement device 1 is provided with a contact member 15 at a location positioned behind the projecting member 14 in the conveying path formed by the conveyor 21 . The contact member 15 is a member with which the dish plate 3 further stacked on the dish plate 3 placed on the conveyor 21 contacts.

FIG. 3 is a top view showing a main part of the plate arrangement device 1. FIG. The starting point S of the conveyor 21 is submerged under the surface of the water indicated by shading in FIG. A water suction port 33 covered with a resin plate formed like a punching metal with 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 pushes the tableware plate 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 circulator, and the discharge ports 31 and 32 are pressed again. is discharged from

FIG. 4 is a front view showing a main part of the plate arrangement device 1. FIG. The arrows shown near the conveyor 21 in FIG. 4 indicate the direction of movement when the conveyor 21 is rotating forward. In FIG. 4, part of the conveyor 21 is indicated by a chain double-dashed line for convenience of illustration.

As shown in FIG. 4, the conveyor 21 extends from under the water surface of the water tank 10 to form a conveying path with an upward slope, and conveys the dishes 3 in the water tank 10 from the starting point S toward the end point E. . Then, the conveyor 21 turns back at the end point E, travels in the opposite direction along the lower side of the conveying route, and traces the route back 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 tension is applied. The upper guide 24U and the lower guide 24L, which guide the movement of the conveyor 21, are made of resin that has a surface friction coefficient smaller than that of stainless steel and that allows the conveyor 21 to easily slide.

For example, when the conveyor 21 automatically detects an increase in the load applied to the conveyor 21 due to the contact of the dish plate 3 with the contact member 15, the conveying direction is temporarily changed by reversing the rotation direction of the conveyor drive mechanism 22. can be reversed to Even if the dish plate 3 contacts the contact member 15, by temporarily reversing the conveying direction of the conveyor 21, the posture of the dish plate 3 in contact with the contact member 15 is corrected. In some cases, the dish plate 3 can be made to pass through the contact member 15 . If the dish plate 3 in contact with the contact member 15 can automatically pass through the contact member 15, the burden on the operator handling the plate arrangement device 1 can be reduced.

As shown in FIG. 4, the plate arrangement apparatus 1 is provided with a rotating disk driving device 40 for rotating the rotating disk 12 below the water tank 10, and a shaft seal device provided below the water tank 10. The rotary shaft of the rotary disc 12 is rotated by the rotational power transmitted through the rotary shaft of the rotary disc 12 that is inserted through.

In addition, as shown in FIG. 4, stoppers 23 on which the dish plates 3 can be hooked are discretely fixed at predetermined intervals on the conveying surface of the conveyor 21 . The space between the stoppers 23 is such that only one tableware plate 3 can be fitted. Here, the interval at which only one tableware plate 3 is fitted means an interval that is approximately the same as the diameter of the circle forming the outer edge of the tableware plate 3 or a space that is slightly wider than the diameter. Therefore, when the tableware plates 3 are fitted between the stoppers 23, the tableware plates 3 are arranged at regular intervals on the conveying surface of the conveyor 21.例文帳に追加

FIG. 5 is a diagram showing an example of movement of the dish plate 3 in the water tank 10. As shown in FIG. Thick arrows shown in FIG.

The discharge port 31 is provided on the left side (the left side in the paper surface of FIG. 5) which is one end side in the longitudinal direction in the oblong tank, and discharges water toward the right side. In addition, the discharge port 32 is provided on the inner side (upper side in the paper surface of FIG. 5) which is one end side in the lateral direction in the horizontally long tank, and the water is directed toward the front side where the start point S of the conveyor 21 is located. Dispense. Therefore, the water flow flowing out from the discharge port 31 flows toward the right side. Also, the water flow flowing out from the discharge port 32 flows toward the near 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 dishes 3 are thrown into the water tank 10 and piled up on the rotating disk 12, the submerged dishes 3 flow out from the rotating force of the rotating disk 12 and the outlets 31 and 32. receive the force of the current. Therefore, as shown in FIG. 5(A), the dish plates 3 initially piled up in the water tank 10 receive the rotational force of the rotating disk 12 and the force of the water flow flowing out from the outlets 31 and 32. move gradually. Further, the water flow flowing out from the discharge port 31 shakes the dish plates 3 which are complicatedly overlapped at the starting point S and its periphery, thereby eliminating the overlapping state of the dish plates 3.例文帳に追加Then, the tableware plate 3 gradually approaches the start point S of the conveyor 21 as shown in FIG. 5(B). When the tableware plate 3 reaches the starting point S of the conveyor 21, it is placed on the conveying surface of the conveyor 21 and conveyed along the conveying path of the conveyor 21 as shown in FIG. 5(C). Then, the dish plate 3 placed on the conveying surface of the conveyor 21 moves from the start point S toward the end point E as shown in FIG. 5(D).

The rotation of the turntable 12 and the flow of water flowing out of the outlets 31 and 32 are appropriately controlled according to the rotational torque detected by the turntable driving device 40 that rotates the turntable 12 . For example, when the rotating disk driving device 40 that rotates the rotating disk 12 detects a rotational torque of about 60% of the rated torque, the rotating disk driving device 40 is temporarily stopped, and the discharge port 31 and the discharge port 32 are discharged. Increases outflow of water. Since such an operation is automatically realized by the control device, even if a large amount of dishes 3 are thrown into the water tank 10, they pile up on the turntable 12 without overloading the turntable driving device 40. The dish plate 3 that has been placed is collapsed by the water flow and moves toward the starting point S.

By the way, as described above, the projecting member 14 is provided in the middle of the conveying path formed by the conveyor 21 . Therefore, the dish plate 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 plate 3 at the location where the protruding member 14 is provided. In the plate arrangement device 1 shown in the lower part of FIG. 6, the state of the dish plate 3 at the location indicated by the circled letter "A", that is, the location where the protruding member 14 is not provided is indicated by the upper left encircling line in FIG. It is illustrated in the column indicated. Also, in the plate arrangement device 1 shown in the lower part of FIG. It is shown in the column indicated by the 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 angle of inclination is such that the tableware plate 3 placed on the conveying surface of the conveyor 21 is inclined toward the wall surface 11, and is, for example, within the range of 1 to 45 degrees, more preferably within the range of 5 to 20 degrees with respect to the horizontal plane. is within. This inclination may be formed over the entire area from the start point S to the end point E of the conveyor 21, or may be formed in a specific area. Since the conveying surface of the conveyor 21 is inclined toward the wall surface 11, the dish plate 3 moves on the conveying route while approaching and contacting the wall surface 11 while the conveyor 21 conveys the dish plate 3.例文帳に追加Therefore, when the tableware plate 3 passes through the place where the protruding member 14 is provided, it contacts the protruding member 14 as illustrated in the column indicated by the upper right encircling line in FIG. 6 . Therefore, in the dish arrangement device 1, for example, the dish plate 3 may move as follows.

FIG. 7 is a diagram showing an example of movement of the dish plate 3 in contact with the projecting member 14. As shown in FIG. Of the tableware plates 3 placed on the conveying surface of the conveyor 21, the tableware plates 3 placed with the front surface facing upward are indicated by reference numeral 3S, and the tableware plates 3 placed with the back surface facing upward are indicated by reference numeral 3S, and the inverted tableware plates 3 (back plates) are placed on the conveyor surface. 3U, and the dish plate 3 further stacked on the other dish plate 3 is indicated by the reference numeral 3K.

As shown in FIG. 7, the dish plate 3 placed on the conveying surface of the conveyor 21 is conveyed in a state of being caught by a stopper 23 fixed to the conveying surface of the conveyor 21. As shown in FIG. However, depending on the state of placing on the conveying surface of the conveyor 21 at the starting point S, the plate 3K may be stacked on the plate 3S as shown in FIG. 7A, for example. However, in the dish arrangement apparatus 1 of this embodiment, the dish plates 3 being conveyed on the conveyor 21 come into contact with the protruding members 14 during transportation, so that the dish plates 3K stacked on the dish plate 3S are also moved by the protruding members 14. agitated by the contact of The dish plate 3K rocked by contact with the protruding member 14 is
Due to the inclination of the conveying surface of the conveyor 21, as shown in FIG. 7B, it slides on the dish plate 3S while touching the wall surface of the wall surface 11. As shown in FIG. Then, as shown in FIG. 7(C), the plate 3K is hooked on a stopper 23 fixed to the conveying surface of the conveyor 21 at an appropriate position, and placed on the conveying surface of the conveyor 21 in a stable state. FIG. 7(C) shows a state in which the tableware plate 3K is placed on the conveying surface with the back surface facing upward, so the reference numeral 3U is added to the reference numeral of the tableware plate 3K. The dish plates 3K and 3S caught by the stoppers 23 are sandwiched and fixed between the stoppers 23 due to the bending of the chain that constitutes the conveyor 21 at the curved portion between the start point S and the end point E. , and is conveyed in a stable state even on an inclination.

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

FIG. 8 is a diagram showing movement of the dish plate 3 at the location where the contact member 15 is provided. The contact member 15 has a gap larger than the thickness of one dish plate 3 and smaller than the thickness of two dish plates 3 between the conveying surface of the conveyor 21 and the lower end of the contact member 15.例文帳に追加It is fixed on the conveying surface in the state. Therefore, the dish plates 3 can pass one by one at the place where the contact member 15 is provided, and the dish plates 3K stacked on the dish plate 3S and the dish plate 3U contact the contact member 15 and pass. Can not do it. Therefore, for example, when the dish plate 3K overlaps the dish plate 3S as shown in FIG. 8(A), the dish plate 3K comes into contact with the contact member 15 as shown in FIG. 8(B). do. The dish plate 3K in contact with the contact member 15 slides on the dish plate 3S due to the inclination of the conveying surface of the conveyor 21, as shown in FIG. 8(B). Then, as shown in FIG. 8(C), the dish plate 3K is caught by a stopper 23 fixed to the conveying surface of the conveyor 21 at an appropriate position, and placed on the conveying surface of the conveyor 21 in a stable state. FIG. 8(C) shows a state in which the tableware plate 3K is placed on the conveying surface with the back surface facing upward, so the reference numeral 3U is added to the reference numeral of the tableware plate 3K.

The conveyor 21 reverses the direction of rotation of the conveyor driving mechanism 22, for example, when an increase in the load applied to the conveyor 21 due to contact of the dish plate 3 with the contact member 15 is automatically detected. Therefore, for example, even if two or more dish plates 3 are piled up and 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 plate 3 are separated from each other. The tableware plate 3 sandwiched between the conveyor 21 and the conveyor 21 descends on the upward slope. Then, the tableware plate 3 in an unstable posture moves on the conveying surface and is stopped by being caught by a stopper 23 at an appropriate position on the conveying surface. Therefore, even if the plate 3 is caught between the contact member 15 and the conveyor 21, the plate arrangement device 1 does not bother the operator handling the plate arrangement device 1.例文帳に追加

9A and 9B are diagrams showing the effects of the projecting member 14 and the contact member 15. FIG. Since the protruding member 14 and the contact member 15 are provided in the middle of the conveying path formed by the conveyor 21, even if there is a dish plate 3K stacked on another dish plate 3, the dish plate 3K is The dish plate 3K moves on the conveying surface of the conveyor 21 while sliding on the dish plates 3S, 3U stably placed on the conveying surface of the conveyor 21 without falling under the water surface of the water tank 10.例文帳に追加Therefore, for example, as shown in FIG. 9, when there are several empty spaces between the adjacent stoppers 23 to which the dish plate 3 is fitted, the dish plate 3K moved by the protruding member 14 or the contact member 15 can be removed. fits into the empty space. That is, as shown in FIG. 9(A), when there are several empty spaces between the adjacent stoppers 23 in which the dish plate 3 is fitted, the dish plate 3K comes into contact with 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 plate 3K is caught by the stopper 23 next to the empty space, as shown in FIG.
fits. Therefore, with the dish arrangement device 1 of the present embodiment, the transfer efficiency is higher than when the protruding member 14 and the contact member 15 are omitted. Since the plate arrangement device 1 of the present embodiment is provided with the plate reversing device 90, not only the dish plate 3S with the front surface facing upward but also the dish plate with the back surface facing upward are placed on the conveying surface of the conveyor 21. Even if a large number of 3U are placed, all of these dish plates 3 can be piled up in the plate inlet 210 of the plate washing device 2 with their surfaces facing upward.

Here, the plate reversing device 90 will be described. FIG. 10 is an example of an enlarged view of the plate reversing device 90. As shown in FIG. A plate reversing device 90 is provided at the end point E of the conveyor 21 . As shown in FIG. 10, the plate reversing device 90 includes a course changing section 91 and a plate reversing section 94, and reverses the front and back of the dish plate 3 with the back surface facing upward. The course changing section 91 brings the upside-down tableware plate 3 conveyed to the conveyor 21 into contact with two course changing members 92 on both sides of the conveyor 21, and moves it from behind by the stoppers 23 fixed to the conveying surface of the conveyor 21. The course of the tableware plate 3 that is kept being pushed is changed obliquely upward. In addition, the plate reversing portion 94 is changed in course obliquely upward by the course changing portion 91, and the tableware plate 3 continues to be pushed from behind by the stopper 23 that moves together with the conveyor 21. Two supporting members support the front portion of the tableware plate 3U. Place it on 95 and turn it upside down.

If the dish plate 3 entering the dish reversing device 90 is, for example, a dish plate 3S whose surface faces upward, the dish plate 3S changes course as shown in FIGS. Do not touch portion 91 . Therefore, the dish plate 3S passes through the plate reversing device 90 as it is.

FIG. 11 is a diagram showing how the dish plate 3S with its surface facing upward passes through the plate reversing device 90. As shown in FIG. As shown in FIG. 11(A), when the dish plate 3S enters the plate reversing device 90, the dish plate 3S approaches the course changing section 91. As shown in FIG. However, the course-changing member 92 of the course-changing part 91 does not contact the edge of the tableware plate 3S whose surface faces upward. Therefore, as shown in FIG. 11(B), the tableware plate 3S passes beside the course changing portion 91 as it is. Then, the dish plate 3S slides down toward the dish washing device 2 on a dish guide rail (not shown) inclined toward the dish washing device 2 side without changing its posture in the plate reversing device 90. - 特許庁As a result, the dish plate 3 is moved to the plate inlet 210 of the plate washing device 2 and stacked on the plate inlet 210 with its surface facing upward.

FIG. 12 is a diagram showing how the dish plate 3U with its back surface facing upward passes through the plate reversing device 90. As shown in FIG. As shown in FIG. 12(A), when the dish plate 3U enters the plate reversing device 90, the dish plate 3U approaches the course changing section 91. As shown in FIG. Then, the edge of the tableware plate 3U comes into contact with the course changing member 92 of the course changing portion 91, and the course is changed diagonally upward as shown in FIG. 12(B). Since the plate 3U continues to be pushed from behind by the stopper 23 fixed to the conveying surface of the conveyor 21 even after coming into contact with the course changing member 92, it moves while sliding on the course changing surface 93. - 特許庁Then, as shown in FIG. 12(C), the front portion of the tableware plate 3U starts to be placed on the support member 95 in the process of passing the course change surface 93 . Then, after the tableware plate 3U passes through the course change surface 93, the front portion of the tableware plate 3U is supported by the support member 95 from below. Since the diverting surface 93 has been passed, the support of the diverting member 92 is lost. The plate 3U continues to be pushed from behind by the stopper 23 even after passing through the course change surface 93, while the support member 95 remains in the same position. A front portion of the plate 3U rides on the support member 95. - 特許庁The tableware plate 3U whose front part has climbed onto the support member 95 continues to be pushed by the stopper 23, and eventually a force in the direction to reverse the positional relationship between the front and rear parts of the tableware plate 3U is applied to the tableware plate 3U. As shown in FIG. 12(F), the tableware plate 3U is turned upside down. The dish plate 3U, which has been turned upside down in the plate reversing device 90, is placed on a dish guide rail (not shown) inclined toward the dish washing device 2 and slides down toward the dish washing device 2 after the surface faces upward. . As a result, the dishes 3U are moved to the dish inlet 210 of the dish washing apparatus 2 and stacked on the dish inlet 210 with the surface facing upward.

If the dish cleaning device 1 having such a dish reversing device 90 is combined with the dish washing device 2 to configure the dish washing system 100, the direction of the dish plate 3 is made uniform, and the dish inlet 210 of the dish washing device 2 is arranged. Only by throwing the dish plates 3 into the water tank 10, the dish plates 3 can be automatically stacked in a dish intake port 210 of the dish washing device 2 with the surfaces thereof facing upward without stacking them on top of each other. . Therefore, the man-hour required for stacking the dish plates 3 can be reduced.

In addition, in the dish arrangement device 1, since the conveying surface of the conveyor 21 is inclined toward the wall surface 11, the dish plates 3 conveyed by the conveyer 21 are less likely to fall below the water surface of the water tank 10. Therefore, even if the tableware plate 3 is placed on the conveying surface of the conveyor 21 in an unstable posture, it is less likely to fall below the water surface of the water tank 10. - 特許庁Therefore, compared with the conventional machine in which the conveying surface of the conveyor 21 is not inclined toward the wall surface 11, the operating efficiency of the conveyor 21 is high.

In addition, as for the dish plates 3 conveyed to the conveyor 21 in a state in which a plurality of plates are piled up, the conveyor 21 leaves an empty space between the stoppers 23 in the middle of the conveying route of the conveyor 21 because it fits in the empty space. The probability of moving while in this state is low. Therefore, with the dish washing system 100 using the above-described dish arrangement device 1, the dishes 3 thrown into the water tank 10 can be piled up in the dish inlet 210 very efficiently.

Further, in the dish arrangement device 1 described above, the dish plates 3 are gathered at the starting point S of the conveyor 21 by the two outlets 31 and 32 and the rotating disk 12 . For example, if the inside of the water tank 10 has a substantially circular shape when viewed from above, and the size of the inside of the water tank 10 is approximately the same in the front-rear direction and the left-right direction, the discharge port 31 and the Even if only one of the discharge ports 32 is provided, it is possible to generate a circulation flow in which the dish plate 3 circulates in the tank of the water tank 10 and move the dish plate 3 to the start point S of the conveyor 21. - 特許庁However, when the inside of the tank 10 is horizontally long as in the dish arrangement device 1, if one of the discharge port 31 and the discharge port 32 is omitted, the inside of the tank of the water tank 10 may be changed. Since the water flow is stagnant on the right and left end sides, the dish plate 3 is difficult to move around in the tank. In this regard, since the dish arrangement device 1 is provided with both the discharge port 31 and the discharge port 32, the dish plate 3 is positioned at the start point S of the conveyor 21 even though the tank 10 is horizontally long. Stop by. Therefore, it is possible to efficiently place the dish plate 3 in the tank of the water tank 10 on the conveying surface of the conveyor 21 . Therefore, in the dish arrangement device 1 described above, if one of the ejection port 31 and the ejection port 32 is omitted, the form that is difficult to realize, that is, the depth of the dish arrangement device 1 is reduced to a dish washing device with a small depth. 2, it is possible to configure the dish washing system 100 so that the front surface of the dish arrangement apparatus 1 and the front surface of the dish washing apparatus 2 are flush with each other.

In addition, in the dish arrangement device 1, the space below the conveying path formed by the conveyor 21 is also designed to accommodate the dish plates 3 in the tank of the water tank 10, so that more space is available in the tank of the water tank 10. It is possible to throw in the tableware plate 3. In such a structure, tension is applied to the conveyor 21 and the conveyor 21 is supported by the upper guide 24U and the lower guide 24L, so that the return portion of the conveyor 21 from the end point E to the start point S reaches the water surface in the tank. It is feasible because it has a structure that does not loosen and fall.

It should be noted that the dish arrangement device 1 is not limited to the mode of use in which the dish plates 3 are stacked on the plate inlet 210 of the dish washing device 2 . The dish arrangement device 1 may, for example, stack the dish plates 3 on a carrier for carrying the dish plates 3 . Further, the plate arrangement device 1 is not limited to a mode of use in which the tableware plates 3 are stacked. For example, the plate arrangement device 1 may place the plate 3 carried out from the water tank 10 on a conveyor for carrying the washed plate 3 on which the sushi prepared by the sushi chef is placed.

Further, the water tank of the dish arrangement device 1 is not limited to a shape in which the inside of the tank is horizontally long. The water tank of the dish arrangement device 1 may have, for example, a cylinder, a rectangular parallelepiped, a cube, a polyhedron, or any other shape. In this case, the conveyer of the plate arrangement device 1 may appropriately form a conveying route corresponding to such various shapes of water tanks.

Moreover, the water tank of the dish arrangement device 1 is not limited to the one into which the dish plate 3 is put. The water tank of the dish arrangement device 1 forms, for example, a part of a circulating water channel for conveying tableware by water circulating at 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 dishes flowing into the water tank from flowing out to the downstream side of the water tank so that the dishes flowing into the water tank gather at the starting point of the conveyor.

In the plate arrangement device 1, the conveying path is basically formed so that the conveyor 21 draws a substantially circular circumference that rotates clockwise when viewed from above. may have been
