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

  The first mold member 30a and the second mold member 30b can be moved up and down with the position in contact with the fourth conveyor C4 as a descending end, and the first mold member 30a located at the rear of the cooked rice conveyance direction is lowered. The second mold member 30b is movable at the lower end in a direction perpendicular to the cooked rice conveyance direction. Further, the third mold member 30c can be moved up and down with a position at a predetermined distance from the fourth conveyor C4 as a descending end. In addition, the 1st type | mold member 30a located in front of the cooked rice conveyance direction can move only in the direction orthogonal to the cooked rice conveyance direction at the descending end, and cannot move in the cooked rice conveyance direction.

Then, the molding position is adjusted so that the position immediately above the cooked rice throwing area T1 of the container T positioned in the cooked rice throwing portion M4 into which the cooked rice R is put in the next process is on the transport path of the shaped cooked rice R.

  In this way, if the cooked rice R is formed into a shape corresponding to the shape of the cooked rice input region T1 formed in the container T and the forming position of the cooked rice R is adjusted as described above, the cooked rice R in the cooked rice input unit M4. The cooked rice R is positioned just above the cooked rice throwing area T1 simply by adjusting the conveyance stop position. Therefore, if the cooked rice R is dropped from there, the cooked rice R will be neatly stored in the cooked rice input region T1 of the container T.

  In the present invention, it is sufficient that the mold 30 can press the cooked rice R in the horizontal direction on the fourth conveyor C4. Therefore, the mold member constituting the mold 30 and its movement are not limited to the present embodiment, and the third mold member 30c that presses the cooked rice R from above may not be provided.

  Moreover, the shape of the molding surface 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 curved in the horizontal direction, the cooked rice R can be molded into a round shape or an elliptical shape. Moreover, if the forming surface is inclined in the horizontal direction, the cooked rice R can be formed into a triangle or the like.

  Furthermore, forming the cooked rice R into a shape corresponding to the shape of the cooked rice input region T1 of the container T is not limited to forming the cooked rice R into a shape having the same size as the shape of the cooked rice input region T1. That is, it is sufficient that the cooked rice R has a shape that does not protrude from the cooked rice throwing region T1 when the cooked rice R is put into the cooked rice throwing region T1.

  In the cooked rice loading unit M4 provided downstream of the molded unit M3 in the direction of conveying the cooked rice, the cooked rice R (that is, the molded unit M3) conveyed from the molded unit M3 to the cooked rice feeding region T1 of the container T supplied from the container supply unit M2. , The shape corresponding to the shape of the cooked rice input area T1 formed in the container T, and the transfer path of the cooked rice R is directly above the cooked rice input area T1 of the container T installed in the cooked rice input section M4. The cooked rice R) whose position has been adjusted is introduced.

  Here, the cooked rice input unit M4 is provided with a container installation unit 42 in which the container T supplied from the container supply unit M2 is installed. Further, a shutter plate (opening / closing portion) 40 is provided above the installed container T, and further, positioning for positioning the cooked rice R formed as described above in the forming portion M3 on the shutter plate 40 in the closed position. A member 41a is provided.

  The positioning member 41a is positioned in front of the cooked rice conveyance direction and regulates the tip position of the cooked rice R. Moreover, the transfer member 41b which moves the cooked rice R shape | molded by the shaping | molding part M3 from the shaping | molding part M3 along a cooked rice conveyance direction and contact | abuts to the positioning member 41a is provided in the cooked rice conveyance direction back of the positioning member 41a. ing.

  Therefore, the cooked rice R moved by the transfer member 41b comes into contact with the positioning member 41a, so that the cooked rice R is positioned immediately above the cooked rice input region T1.

  Thereby, in the cooked rice throwing-in part M4, after positioning the cooked rice R in the positioning part 41 just above the cooked rice throwing-in area | region T1, the cooked rice R on the shutter board 40 is moved by moving the shutter board | plate 40 from a closed position to an open position. It is dropped into the cooked rice throwing area T1 formed in the container T.

  A fifth conveyor C5 provided with a load cell (not shown) is disposed in the total weight measuring unit M5 provided downstream of the cooked rice input unit M4 in the cooked rice conveyance direction. Therefore, when the container T sent from the cooked rice throwing portion M4 is conveyed by the fifth conveyor C5, the weight of the container T charged with the cooked rice R, that is, the total weight is measured. And a measurement result is sent to the following container distribution part M6.

  A container sorting unit M6 provided downstream of the total weight measuring unit M5 in the direction of transporting cooked rice sorts the containers T in two directions based on the measurement results obtained by the total weight measuring unit M5. That is, a cooked rice smoothing section M7 is provided downstream of the container sorting section M6 in one cooked rice conveyance direction, and a container discharge section M8 is provided downstream of the other cooked rice conveyance direction. And when the total weight of the container T which is a measurement result in the total weight measuring unit M5 is within a predetermined range, it is distributed to the cooked rice leveling unit M7 in the container distribution unit M6, and the total weight of the container T Is outside the predetermined range, it is distributed to the container discharge section M8 in the container distribution section M6.

  Here, a sixth conveyor C6 is provided in front of the container sorting unit M6. Further, the container allocating portion M6 is provided with a allocating member 60 including a protruding plate 61 having a width equal to or larger than the width of the container T and capable of appearing and retracting in a direction crossing the sixth conveyor C6. A leveling member 70 constituting a cooked rice leveling unit M7 is installed above the downstream side of the sixth conveyor C6 with respect to the container sorting unit M6. The leveling member 70 has a leveling plate 71 that can be moved up and down with a position at a predetermined distance from the sixth conveyor C6 as a descending end. Further, a discharge conveyor 80 constituting the container discharge unit M8 is installed on the opposite side of the distribution member 60 across the sixth conveyor C6. The discharge conveyor 80 is formed by a plurality of rotatable rollers, and is inclined downward from the position facing the sorting member 60 as a starting point.

  The container T (the container T charged with the rice R) conveyed from the total weight measuring unit M5 is processed as follows by the container distributing unit M6, the cooked rice smoothing unit M7, and the container discharging unit M8. .

  That is, when the total weight of the container T is within a predetermined range, the protruding plate 61 of the sorting member 60 constituting the container sorting unit M6 does not project. Therefore, the container T is conveyed to the sixth conveyor C6 and reaches the cooked rice leveling part M7. And the leveling board 71 of the leveling member 70 which comprises the cooked rice leveling part M7 descend | falls, and the cooked rice R thrown into the container T is leveled. After that, side dishes are placed on the container T by the operator.

  Further, when the total weight of the container T is out of the predetermined range, the protruding plate 61 of the sorting member 60 protrudes, and the container T moves from the sixth conveyor C6 to the discharge conveyor 80 constituting the container discharge portion M8. It is guided. Thereby, the container T slides on the roller which forms the discharge conveyor 80, and is discharged | emitted out of an apparatus.

  Next, the operation of the cooked rice throwing apparatus having the above configuration will be described.

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

  When the start button is pressed, in the cooked rice metering unit M1, the cooked rice R sent from the hopper 93 is volume-measured in the main metering unit 10, and the main metered cooked rice RM is acquired. The obtained main weighed cooked rice RM is weighed by the load cell while being conveyed on the second conveyor C2, and the auxiliary weighing unit 14 is supplemented with the auxiliary weighed cooked rice RS of the weight difference between the set weight value and the measured weight value. The cooked rice R targeted for the set weight value is acquired.

  At this time, the weight of the main weighed cooked rice RM (symbol A) being transported on the third conveyor C3 is already measured by the load cell when it is transported on the second conveyor C2. Therefore, in the first replenishment unit 14a provided in the auxiliary weighing unit 14, the auxiliary weighing which is the cooked rice of the weight difference between the set weight value of the cooked rice R and the measured weight value of the main measured cooked rice RM (symbol A) in the load cell. The cooked rice RS (symbol A ′) is measured and acquired by the auxiliary measurement cooked rice acquisition unit 14 a-6, and waits for the timing when the main weighed cooked rice RM (symbol A) reaches directly below.

  On the other hand, the weight of the main weighed cooked rice RM (symbol B) conveyed on the second conveyor C2 is measured by a load cell provided on the second conveyor C2.

  When shifting from the state shown in FIG. 5 to the state shown in FIG. 6 and the main weighing rice RM (symbol A) conveyed on the third conveyor C3 reaches directly below the auxiliary weighing rice acquisition unit 14a-6, the shutter is moved. 14a-8 opens. Then, the auxiliary measurement cooked rice RS (reference A ′) in the auxiliary measurement cooked rice acquisition unit 14 a-6 falls and is guided by the lower guide 14-7 to be replenished to the main measurement cooked rice RM (reference A). Thereby, the cooked rice R targeted for the set weight value is acquired.

  On the other hand, in the second replenishing unit 14b provided in the auxiliary weighing unit 14 corresponding to the main weighing rice RM (reference B) being conveyed on the third conveyor C3 through the second conveyor C2, The auxiliary weighed cooked rice RS (symbol B ′), which is the difference in weight between the set weight value of R and the measured weight value of the main weighed cooked rice RM (symbol B) in the load cell of the second conveyor C2, is the auxiliary weighed cooked rice acquisition unit. It is obtained by measuring at 14b-6. And it waits for the timing when main measurement cooked rice RM (code | symbol B) arrives directly under.

  Further, the main weighed cooked rice RM (reference A) being transported on the second conveyor C2 is measured by the load cell.

  When shifting from the state shown in FIG. 6 to the state shown in FIG. 7, the main weighing rice RM (symbol B) conveyed on the third conveyor C <b> 3 has now reached directly below the auxiliary weighing rice acquisition unit 14 b-6. Sometimes the shutter 14b-8 opens. Then, the auxiliary weighed cooked rice RS (symbol B ′) in the auxiliary weighed cooked rice acquisition unit 14 b-6 is guided by the lower guide 14-7 and supplemented to the main weighed cooked rice RM (symbol B), and the set weight value is targeted. Cooked rice R is acquired.

  On the other hand, in the 1st replenishment part 14a provided in the auxiliary weighing part 14 corresponding to the main measurement rice RM (code | symbol B) currently conveyed by the 3rd conveyor C3 through the 2nd conveyor C2, the cooked rice Auxiliary weighed cooked rice RS (symbol A ′), which is a difference in weight between the set weight value of R and the measured weight value of main weighed cooked rice RM (symbol A) at the load cell of the second conveyor C2, is an auxiliary weighed cooked rice acquisition unit. It is measured and acquired at 14a-6. And it waits for the timing when the main measurement cooked rice RM (symbol A) reaches directly below.

  Furthermore, the weight is measured with the load cell about the main measurement rice RM (code | symbol B) currently conveyed by the 2nd conveyor C2.

  Thereafter, the mode shown in FIG. 6 and the mode shown in FIG. 7 are alternately repeated.

  As described above, in the present embodiment, the first and second supplementary units 14a and 14b constituting the auxiliary weighing unit 14 alternately measure and acquire the auxiliary measured cooked rice RS with respect to the main measured cooked rice RM. This is replenished to the corresponding main weighing rice. Therefore, it is possible to sufficiently ensure the weighing time of the auxiliary weighing rice RS (specifically, the weighing time of the auxiliary weighing rice RS by the load cell, which is a measuring means built in the weighing drive unit 14-9), and the processing speed. It is possible to auxiliary measure rice with high accuracy without dropping the rice.

  Thereby, the dispersion | variation with respect to the setting weight value of the cooked rice R obtained by supplementing the auxiliary measured cooked rice RS to the main measured cooked rice RM is suppressed.

  While the cooked rice weighing unit M1 obtains the cooked rice R, in the container supply unit M2, the lowermost container T accommodated in the stock unit 21 is taken out by the container take-out unit 22 and conveyed to the container carrying conveyor 20. It is set in the container installation part 42 of the cooked rice input part M4.

  Now, the cooked rice R acquired by the cooked rice weighing unit M1 is sent to the molding unit 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. Molded with the mold 30. When the formation 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, so that the cooked rice R is placed on the transport path of the cooked rice R. The cooked rice R is positioned so that the position just above the cooked rice input region T1 of the container T positioned at M4 is located. The molding and positioning may be performed at the same time.

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

  In the cooked rice input unit M4, the container T sent from the container supply unit M2 is installed in the container installation unit 42 as described above. The cooked rice R from the molding part M3 is pushed along the cooked rice conveying direction by the rear positioning member 41b and brought into contact with the front positioning member 41a, so that the cooked rice R is put into the container T on the shutter plate 40. It is positioned immediately above the region T1. When the shutter plate 40 moves to the open position, the cooked rice R on the shutter plate 40 is automatically dropped into the cooked rice throwing area T1 formed in the container T.

  The container T into which the cooked rice R has been fed by the cooked rice throwing unit M4 is weighed in the total weight measuring unit M5. It is distributed to the leveling part M7. And the cooked rice R thrown into the container T in the cooked rice smoothing section M7 is smoothed and sent to the next process (for example, a side dish serving process). If the total weight of the container T is out of the predetermined range, the container sorting unit M6 sends the container T to the container discharge unit M8 and discharges it from the discharge conveyor 80 to the outside of the apparatus.

  As described above, in the cooked rice throwing apparatus according to the present embodiment, the cooked rice throwing area T1 formed in the container T has a shape corresponding to the shape, and the position immediately above the cooked rice throwing area T1 is on the transfer path of the cooked rice R. The rice R is shaped by adjusting the position. Then, the cooked rice R is transported along the transport direction, positioned right above the cooked rice throwing area T1, and dropped into the cooked rice throwing area T1 of the container T.
