However, the first lateral regulating portion 13-1 does not have to be a roller 13-1a, and may be a plate-shaped member 13-1b. That is, the first side regulation unit 13-1 has a configuration of only the roller 13-1a, a configuration of only the plate-shaped member 13-1b, a configuration of the roller 13-1a and the plate-shaped member 13-1b, and the like. Can be adopted. Further, even when the roller 13-1a is provided, the roller 13-1a does not have to have a plurality of stages in the vertical direction (two stages in the present embodiment), and may be one stage. .. Further, the plate-shaped member 13-1b does not have to have a plurality of grooves 13-1bs extending in the entire length in the vertical direction. When the rollers 13-1a are provided in a plurality of stages in the vertical direction, if the distance between the pair of rollers 13-1a located in the lower stage is narrower than the distance between the pair of rollers 13-1a located in the upper stage, the cooked rice R can be obtained. It can be sent downward while being compressed while maintaining a constant density.

As shown in FIG. 5, the pair of second side regulation units 13-2 are each composed of panels 13-2a. The panel 13-2a was installed so that the rollers 13-1a constituting the first lateral regulating portion 13-1 penetrated in the axial direction, separated into two in the lateral direction, and shifted from each other.

In the present embodiment, the panel 13-2aa and the panel 13-2ab can be moved independently in the axial direction of the roller 13-1a, and for example, only the distance between the opposing panels 13-2aa is narrowed. Can be done.

By the way, the supply unit 13 and the measuring basin 11 are also controlled by the control unit S described above. That is, as shown in FIG. 7, the control unit S includes a first position adjusting motor B1 that causes a pair of first side regulation units 13-1 to approach and separate from each other, and a pair of second side regulation units 13-1. A second position adjusting motor B2 that moves 13-2 closer to and away from each other, a split shutter drive motor B3 that moves the split shutter 11b in the horizontal direction, and a measure adjustment plate drive motor that moves the measure adjustment plate 11c in the vertical direction. It controls the operations of B4, the frame body drive motor B5 that moves the frame body portion 11a in the horizontal direction, and the roller drive motor B6 that rotates the rollers 13-1a when the rice R is sent downward.

As a result, when the set weight value of the cooked rice input by the operator is sent from the input unit 94 to the control unit S, the control unit S passes through the first position adjusting motor B1 according to the set weight value of the cooked rice. The distance between the pair of first side regulation units 13-1 and the distance between the pair of second side regulation units 13-2 via the second position adjustment motor B2 are set by the amount adjustment plate drive motor B4. The height of the scale adjusting plate 11c is adjusted via the above.

That is, the cross-sectional area of the cooked rice R sent from the supply unit 13 to the measuring basin 11 is defined by the first side regulation unit 13-1 and the second side regulation unit 13-2, and is sent to the measuring basin 11. Since the height of the cooked rice R is defined by the distance (height) between the split shutter 11b and the amount adjustment plate 11c, the volume of cooked rice R in the measuring basin 11 is obtained from this cross-sectional area and height. Be done. Therefore, the control unit S has the first side regulation unit 13-1, the second side regulation unit 13-2, and the amount adjustment plate 11c so that the volume of the cooked rice R corresponds to the set weight value. Is to adjust.

Further, the above-mentioned auxiliary weighing unit 14 is arranged directly above the third conveyor C3 arranged downstream of the second conveyor C2 in the rice transport direction.

A part of the cooked rice in the hopper 93 described above is supplied to the auxiliary measuring unit 14 via the auxiliary conveyor 15, and further, the cooked rice R measured by the load cell of the second conveyor C2. Weight data is to be transmitted. Then, in the auxiliary weighing unit 14, the excess or deficiency weight of the actual cooked rice R with respect to the set weight value is calculated from the weight value (set weight value) set by the operator and the measured value in the load cell, and the cooked rice R corresponding to the deficient weight is calculated. Is generated and supplied to the cooked rice R being conveyed on the third conveyor C3.

As a result, the cooked rice R targeting the set weight value is sent from the cooked rice generation unit M1 to the molding unit M3.

In the present embodiment, the auxiliary weighing is performed in this way to improve the accuracy of the amount of cooked rice R, but the auxiliary weighing does not necessarily have to be performed.

Then, the operator operates the operation panel 94a to input a desired set weight of cooked rice R (for example, an arbitrary weight within the range of 150 g to 300 g).

The container supply unit M2 for supplying the container T into which the cooked rice R is charged includes a tower-type stock unit (container storage unit) 21 for stacking and accommodating the containers T. Further, the container supply section M2 is provided with the above-mentioned container transfer conveyor 20 extending from directly below the stock section 21 to the cooked rice charging section M4. At the lower part of the stock part 21, a container take-out part 22 is installed which sucks and takes out the lowermost container T housed and drops it on the container transport conveyor 20. Further, a pushing portion 23 is provided which pushes the container T to which the container transport conveyor 20 is conveyed and pushes it into a predetermined position of the cooked rice charging portion M4.

The container T housed in the stock section 21 by such a container supply section M2 is attracted one by one by the container take-out section 22 in order from the bottom and placed on the container transfer conveyor 20, and is placed on the container transfer conveyor 20. After being conveyed, it is set in the rice container M4 by the pushing unit 23.

In the molded portion M3 located downstream in the cooked rice transport direction of the cooked rice generating section M1, the cooked rice R generated by the cooked rice generating section M1 is molded into a shape (for example, a quadrangle) corresponding to the cooked rice input region T1 formed in the container T. To do. Further, the position (molding position) of the cooked rice R is adjusted so that the transport path of the molded cooked rice R is directly above the cooked rice charging region T1 of the container T supplied to the cooked rice feeding unit M4.

A pair of second mold members 30b that are arranged to face each other and press the cooked rice R in a direction orthogonal to the transport direction, and a third mold member 30c that presses the cooked rice R from above to level the upper surface. It is configured.

The first mold member 30a and the second mold member 30b can be raised and lowered with the position of contact with the fourth conveyor C4 as the lowering end, and the first mold member 30a located rearward in the rice transport direction is lowered. The second mold member 30b is movable at the end in the front-rear direction in the cooked rice transport direction and in a direction orthogonal to the front-back direction, and the second mold member 30b is movable in a direction orthogonal to the cooked rice transport direction at the descending end. Further, the third mold member 30c can be moved up and down with the lowering end at a position separated from the fourth conveyor C4 by a predetermined distance. The first mold member 30a located in front of the cooked rice transport direction can move only in the direction orthogonal to the cooked rice transport direction at the descending end, and cannot move in the cooked rice transport direction.

In the present application, "pressing the cooked rice R in the direction along the transport direction (rice rice transport direction)" means pressing the cooked rice R along the transport line. Therefore, not only the cooked rice R is pressed in the cooked rice transport direction, but also the first mold member 30a located in front of the cooked rice transport direction can be moved in the front-back direction in the cooked rice transport direction, which is opposite to the cooked rice transport direction. The cooked rice R may be pressed in the direction, or the cooked rice R may be pressed from two directions, the cooked rice transporting direction and the direction opposite to the cooked rice transporting direction.

In such a molding portion M3, the fourth conveyor C4 is temporarily stopped, and the first mold members 30a, 30a, the second mold members 30b, 30b, and the third mold member 30c are positioned at appropriate positions. The cooked rice R on the fourth conveyor C4 is formed into a shape corresponding to the shape of the cooked rice input region T1 formed in the container T.

Further, at the time of molding, the positions of the cooked rice R to be molded on the fourth conveyor C4 are adjusted by the first mold members 30a and 30a, the second mold members 30b and 30b and the third mold member 30c. Then, the molding position is adjusted so that the position directly above the cooked rice charging region T1 of the container T positioned at the cooked rice feeding portion M4 into which the cooked rice R is charged in the next step is on the transport path of the molded cooked rice R.

If the cooked rice R is molded into a shape corresponding to the shape of the cooked rice charging region T1 formed in the container T in this way, and the molding position of the cooked rice R is adjusted as described above, the cooked rice R is formed in the cooked rice filling section M4. The cooked rice R is positioned directly above the cooked rice charging region T1 simply by adjusting the transport stop position of the cooked rice R. Therefore, if the cooked rice R is dropped from there, the cooked rice R will be neatly contained in the cooked rice input region T1 of the container T.

In the present invention, it suffices for the molding die 30 to be able to press the cooked rice R horizontally on the fourth conveyor C4. Therefore, the mold member forming the molding mold 30 and its movement are not limited to the present embodiment, and the third mold member 30c for pressing the cooked rice R from above may not be provided.

Further, the shapes of the molded surfaces of the first mold members 30a and 30a and the second mold members 30b and 30b can be freely set. For example, if the molding surface is shaped to be curved in the horizontal direction, cooked rice R can be molded into a round shape or an elliptical shape. Further, if the molding surface is inclined in the horizontal direction, the cooked rice R can be molded into a triangle or the like.

Further, molding the cooked rice R into a shape corresponding to the shape of the cooked rice charging region T1 of the container T is not limited to molding the cooked rice R into a shape having the same size as the cooked rice feeding region T1. That is, when the cooked rice R is charged into the cooked rice input region T1, the cooked rice R may have a shape that does not protrude from the cooked rice input region T1.

A leveling member 70 constituting the cooked rice leveling section M7 is installed above the container sorting section M6 of the sixth conveyor C6 on the downstream side in the cooked rice transport direction. The leveling member 70 has a leveling plate 71 that can be raised and lowered with a lowering end at a position separated from the sixth conveyor C6 by a predetermined distance. Further, a discharge conveyor 80 constituting the container discharge portion M8 is installed on the opposite side of the distribution member 60 with the sixth conveyor C6 in between. The discharge conveyor 80 is formed of a plurality of rotatable rollers, and is inclined downward starting from a position facing the distribution member 60.

The container T (container T into which the cooked rice R is charged) conveyed from the gross weight measuring unit M5 is processed by the container sorting unit M6, the cooked rice leveling unit M7, and the container discharging unit M8 as follows. ..

That is, when the total weight of the container T is within a predetermined range, the protruding plate 61 of the distribution member 60 constituting the container distribution portion M6 does not project. Therefore, the container T is conveyed to the sixth conveyor C6 and reaches the cooked rice leveling portion M7. Then, the leveling plate 71 of the leveling member 70 constituting the cooked rice leveling portion M7 is lowered, and the cooked rice R charged into the container T is leveled. After that, the worker arranges the side dishes in the container T.

When the total weight of the container T is out of the predetermined range, the projecting plate 61 of the distribution member 60 projects, and the container T moves from the sixth conveyor C6 to the discharge conveyor 80 constituting the container discharge unit M8. Is guided. As a result, the container T slides on the rollers forming the discharge conveyor 80 and is discharged to the outside of the device.

Next, the operation of the cooked rice feeding device having the above configuration will be described.

When cooked rice is put in the hopper 93 and the container T into which the cooked rice R is put is accommodated in the container supply unit M2, the operator operates the input unit 94 to set the set weight of the cooked rice R, the type of the container T, and the production. Enter the quantity etc. and press the start button. In the present embodiment, a plurality of types of the container T are registered in advance, and the container T housed in the container supply unit M2 is formed in the container T only by selecting from the registered containers T. The shape and position of the cooked rice input region T1 are set. Therefore, in the molding unit M3, the cooked rice R corresponding to the shape and position of the set cooked rice input region T1 is molded.

When the start button is pressed, the cooked rice R sent from the hopper 93 is volumetrically weighed by the main measuring unit 10 in the rice generating unit M1 as described above, and the cooked rice R corresponding to the set weight is generated. As described above, in the supply unit 13 constituting the main measuring unit 10, the pair of first side regulation units 13-1 and the pair of second side regulation units 13-2 approach and separate from each other. It is provided as possible. Therefore, the amount of cooked rice introduced into the frame body portion 11a by appropriately adjusting the interval between the pair of first side regulating portions 13-1 and the pair of second side regulating portions 13-2. Is easily adjusted.

If the weight of the produced cooked rice R is insufficient with respect to the set weight value, the auxiliary weighing unit 14 compensates for the shortage, and finally the cooked rice R with the set weight value as the target is generated.

In this way, the cooked rice R is generated in the cooked rice generation section M1, while in the container supply section M2, the lowermost container T housed in the stock section 21 is taken out by the container take-out section 22 and placed on the container transport conveyor 20. It is transported and set in the container installation section 42 of the cooked rice charging section M4.

By the way, the cooked rice R generated by the cooked rice generating section M1 is sent to the molding section M3 so as to have a shape and position corresponding to the cooked rice input region T1 of the container T on the temporarily stopped fourth conveyor C4. It is molded by the molding die 30. When the molding of the cooked rice R is completed, the first mold members 30a, 30a and the second mold members 30b, 30b are integrally moved in the horizontal direction, and the cooked rice charging portion is placed on the transport path of the cooked rice R.

Adjust the spacing between the pair of first lateral regulating portions 13-1 and the spacing between the pair of second lateral regulating portions 13-2 so that the cross-sectional shape in the horizontal direction corresponds to the cross-sectional shape in the horizontal direction. You may do so. By doing so, the degree of the shape change of the cooked rice R at the time of molding in the molding portion M3 is alleviated, so that the variation in the density of the cooked rice R after molding is suppressed.

In particular, in the present embodiment, as described above, since the panel 13-2aa and the panel 13-2ab can move independently in the axial direction of the roller 13-1a, the cross-sectional shape of the cooked rice R Can be shaped not only as a quadrangle but also as a triangle or trapezoid.

Here, in FIGS. 8A to 8C, the cross-sectional shape of the cooked rice R in the main measuring section 10 is on the left side of the arrow, and the cross-sectional shape of the cooked rice R molded in the molding section M3 is on the right side of the arrow. Shown in.

As shown in FIG. 8A, when the main measuring unit 10 has a square cross section, the molding shape is preferably square or round. Further, as shown in FIG. 8B, when the main measuring portion 10 has a rectangular cross section, a rectangular or elliptical molding shape is suitable. Further, as shown in FIG. 8C, when the main measuring portion 10 has a trapezoidal cross section, a triangular shape or the like is suitable as the molding shape. However, the shape pattern of FIG. 8 is merely an example, and is not limited to this combination, and other shapes may be adopted.

The cooked rice R that has been molded in the molding section M3 in this way is conveyed to the cooked rice charging section M4.

As described above, the container T sent from the container supply unit M2 is installed in the container installation unit 42 in the cooked rice charging unit M4. The cooked rice R from the molding portion M3 is pushed by the rear positioning member 41b along the rice transport direction and comes into contact with the front positioning member 41a, so that the cooked rice R is put into the cooked rice in the container T on the shutter plate 40. It is positioned directly above the region T1. Then, when the shutter plate 40 moves to the open position, the cooked rice R on the shutter plate 40 is automatically dropped and thrown into the cooked rice charging region T1 formed in the container T.

The container T into which the cooked rice R is charged in the cooked rice charging section M4 is weighed by the total weight measuring section M5, and when the total weight of the container T is within a predetermined range, the cooked rice is sorted by the container sorting section M6. It is distributed to the leveling section M7. Then, the cooked rice R put into the container T is leveled by the cooked rice leveling unit M7 and sent to the next step (for example, a side dish serving step). When the total weight of the container T is out of the predetermined range, the container T is sent to the container discharge unit M8 by the container distribution unit M6, and is discharged from the discharge conveyor 80 to the outside of the device.

As described above, in the cooked rice charging device of the present embodiment, the cooked rice filling region T1 formed in the container T has a corresponding shape, and the position directly above the cooked rice feeding region T1 is on the transport path of the cooked rice R.
