Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted.

  As shown in FIG. 1, the cooked rice splitting device (dough splitting device) M <b> 1 according to the present embodiment has a transport conveyor (transport means) 3, a first weighing conveyor (first scale) on a pedestal 2 that can be moved by a caster 1. 1 weighing and conveying means) 4 and a second weighing conveyor (second weighing and conveying means) 5 are arranged along the conveying direction from the upstream side to the downstream side. In addition, on the upper rear end side of the conveyor 3, a sending unit (sending means) 6 that forms cooked rice (dough) into a sheet shape and sends it out is disposed.

  On the rear side of the pedestal 2 (on the right side in FIG. 1), a lifter 9 is provided for moving the rice container 8 up and down along a pair of vertical rails 7 extending in the vertical direction. The lifter 9 lifts the cooked rice container 8 to the position of the hopper 10 installed at the top, and the flipper 23 provided at the upper end of the lifter 9 is turned upside down toward the hopper 10, thereby Cooked rice is put into the hopper 10.

  The hopper 10 is provided with a first unrolling roller 11 for unloading the cooked rice. The first unrolling roller 11 is unrolled below the first unrolling roller 11.

Then, the cooked rice that has been unwound by the second unrolling roller 22 is put into the delivery unit 6 described above.

  In the delivery unit 6, a first roller pair 13 having a total of two pairs of left and right pairs is arranged in the vertical direction. In the first roller pair 13, the interval between the first roller pair 13 b located at the lower stage is narrower than the interval between the first roller pair 13 a located at the upper stage. Therefore, the cooked rice is compressed and formed into a sheet shape by being sent downward from above by the first roller pair 13a, 13b.

  A pair of left and right second rollers 14 is disposed below the first roller pair 13b located in the lower stage. The second roller pair 14 can be moved toward and away from each other, and the thickness of the continuous cooked rice fed from the first roller pair 13 is adjusted according to the distance between the second roller pair 14. Then, it is sent out downward and placed on the conveyor 3. Then, it is conveyed from the conveyor 3 to the first weighing conveyor 4.

  Between the transport conveyor 3 and the first weighing conveyor 4, the sheet-shaped cooked rice thus transported from the transport conveyor 3 to the first weighing conveyor 4 intersects the transport direction (here, A cutter (dividing means) 15 for dividing in a direction substantially perpendicular to the conveying direction) is arranged. Therefore, the cooked rice in a sheet form is divided by the cutter 15 while being conveyed from the conveyor 3 to the first weighing conveyor 4, and the divided cooked rice conveyed from the first weighing conveyor 4 is the second It is conveyed to the weighing conveyor 5. The details of the timing of dividing the cooked rice by the cutter 15 will be described later.

  The first weighing conveyor 4 is provided with a load cell 4a for measuring the weight of continuous sheet-shaped cooked rice sent from the conveyor 3 over time. Further, the second weighing conveyor 5 is provided with a load cell 5a for measuring the weight of the divided cooked rice conveyed from the first weighing conveyor 4. Accordingly, the first weighing conveyor 4 conveys the weight of cooked rice conveyed from the conveying conveyor 3 over time, and the second weighing conveyor 5 divides the rice that has been conveyed from the first weighing conveyor 4.

  In the cooked rice dividing apparatus (dough dividing apparatus) M1 of the present embodiment, the size of the divided cooked rice is 110 mm long, 65 mm wide, and 15 mm high (thickness), and about 3000 per hour. It has the ability to manufacture sheets.

  A forming apparatus M2 for forming the divided cooked rice into a predetermined shape (for example, forming a triangular rice ball shape) is disposed on the downstream side in the conveying direction of the cooked rice dividing apparatus M1. Then, the divided cooked rice conveyed on the second weighing conveyor 5 is transferred from the cooked rice dividing apparatus M1 by the transfer arm 16.

  The molding apparatus M2 includes a first molding table 18 in which a plurality of molding holes (not shown) into which the cooked rice transferred by the transfer arm 16 is pushed are formed at predetermined intervals and intermittently rotated in the lateral direction.

A second molding table 19 that is formed and rotated intermittently in the vertical direction, and the second molding table 19 (from the first molding table 18 (molding hole)) while folding the rice on which the ingredients are placed is folded. And a discharge conveyor 21 for discharging the finished rice ball formed by the second forming table 19 to the outside of the machine.

  Next, a control system of the cooked rice splitting apparatus M1 having the above-described configuration will be described with reference to FIG.

  In FIG. 2, the operation of the cooked rice dividing apparatus M <b> 1 is controlled by a control unit (control means) 30. Specifically, the control unit 30 controls the speed of the circular movement of the first weighing conveyor 4 and the second weighing conveyor 5 and is based on the weight of the cooked rice R measured by these conveyors 4 and 5. The cutter 15 is operated via the cutter driving unit 31 at a predetermined timing, and the continuous sheet-shaped cooked rice R is divided. The control unit 30 controls the driving of the first roller pair 13 via a first roller pair driving unit (driving means) 33 that is a motor, and the second roller pair moving unit 34 controls the second. The distance between the roller pairs 14 is controlled. The drive control of the first roller pair 13 is executed by controlling the speed or torque of the first roller pair drive unit 33 that drives the first roller pair 13. Further, the control unit 30 functions as a length measuring unit (length measuring means) that measures the length of the divided cooked rice R from the conveyance speed of the cooked rice R by the first weighing conveyor 4 and the division timing by the cutter 15. have.

  Next, the process of dividing the cooked rice R by the control unit 30 in the cooked rice splitting apparatus M1 of the present embodiment will be described.

  In the dividing process of cooked rice R, the control system shown in FIG. 3 is used. Therefore, the dividing operation of the cooked rice R will be specifically described using the flowchart of FIG. 4 with reference to the control system shown in FIG.

  The cooked rice R is put into the hopper 10, the second roller pair 14 is set at a predetermined interval, the first roller pair 13 starts rotating, the conveyor 3 starts rotating, and the control unit 30 When the first weighing conveyor 4 and the second weighing conveyor 5 controlled in the same manner start rotating in the same manner, the continuous cooked rice R molded into a sheet shape is sent out from the sending section 6 and placed on the conveying conveyor 3. The transport is started.

  Then, the control unit 30 controls the first weighing conveyor 4 to the first speed (for example, 1,081 mm / sec), whereby the cooked rice R starts to be fed at the first speed (step S1). .

  When the supply of the cooked rice R is started in this way, the continuous weighing of the continuous sheet-shaped cooked rice R sent from the conveyor 3 is started by the first weighing conveyor 4 (step S2). Here, the weight of the portion of the cooked rice R placed on the first weighing conveyor 4 is measured, but at the first speed, the transfer rate of the cooked rice R is too fast, so the reaction speed of the load cell 4a cannot catch up, and the cooked rice. Only a rough weight of R can be measured. In the present embodiment, the first speed is a speed at which only a rough weight of the cooked rice R can be measured, but may be a speed at which an accurate weight can be measured. However, it is desirable that the first speed be as high as possible.

  Now, while measuring the cooked rice R at the first speed, it is determined whether the measured weight value at the load cell 4a has reached N% (for example, 80%) of the target weight value (for example, 100 g) of the cooked rice R (step). S3). As will be described later, since the second speed is slower than the first speed, it is desirable that the amount of cooked rice R conveyed at the first speed is as large as possible in order to perform rapid processing. In FIG. 3, the portion indicated by the symbol Wm is a portion corresponding to N% of the cooked rice R.

  In addition, including the numerical values in the case described below, such as 100 g of the target weight value, 80% as N% with respect to the target weight value, or specific numerical values of the first speed and the second speed described later, The present invention is not limited to the numerical values exemplified in the embodiments.

  When the weight of the cooked rice R reaches N% of the target weight value, the first weighing conveyor 4 is decelerated to a second speed (for example, 65 mm / sec) that is slower than the first speed. The supply of cooked rice R is continued (step S4). The second speed is set to a speed that allows the reaction speed of the load cell 4a to follow the transport speed of the cooked rice R. Therefore, at the second speed, the exact weight of the cooked rice R is measured.

  In the present embodiment, the rough weight of the cooked rice R is measured by the load cell 4a in step S3, and when it reaches a predetermined ratio (N%) with respect to the target weight value, the process proceeds to step S4. Although it is supposed to decelerate to the 2nd speed, for example, cooked rice R introduced into the 1st measurement conveyor 4 by control part 30 based on the conveyance speed and conveyance time of cooked rice R in the 1st measurement conveyor 4 If it is determined in step S3 that the estimated weight has reached a preset weight, the process may proceed to step S4. That is, the weight of the cooked rice R introduced into the first weighing conveyor 4 is measured or estimated by some method, and it is determined in step S3 that the weight has reached a predetermined ratio (N%) with respect to the target weight value. Then, what is necessary is just to make it transfer to step S4.

  Here, the weight of the portion of the cooked rice R that is not placed on the first weighing conveyor 4, that is, the weight of the portion between the transfer conveyor and the weighing conveyor (hereinafter referred to as “crossover portion”) is not measured. Therefore, when the cooked rice R is divided by the cutter 15 at the transfer portion, the weight of the divided cooked rice R is the weight measured on the first weighing conveyor 4 and the portion that is not measured by the first weighing conveyor 4 at the time of division ( That is, the weight is the weight of the transition portion (the portion indicated by the symbol Wx in FIG. 3).

  Accordingly, the sum of the measured weight value (first measured weight value) of the cooked rice R in step S4 and the predicted transition portion weight value (predicted weight value) set in advance as the weight of the transition portion described above is the target weight. It is determined whether or not the value (100 g in this embodiment) has been reached (step S5). In FIG. 3, the combined portion of the portion indicated by reference sign Ws and the portion indicated by reference sign Wm is the portion of cooked rice R on which the weight is measured.

  When the sum of the measured weight value of the cooked rice R and the predicted weight of the transition portion reaches the target weight value, the cutter driving unit 31 is driven and the cooked rice R is divided by the cutter 15 (step S6). That is, if the predicted weight value of the transition part is set to 10 g, for example, when the measured weight value of the cooked rice R reaches 90 g in step S5, the sum of both has reached the target weight value of 100 g. In step S6, the cooked rice R is divided by the cutter 15 at the arrival timing.

  In the present embodiment, steps S1 to S6 correspond to the first control.

  Subsequently, the cooked rice division length control process is performed so that the length of the divided sheet-shaped cooked rice R becomes a predetermined length (step S7). However, the control process is not essential, and therefore, when step S6 is completed, the process may immediately proceed to the next step S8. Details of step S7 will be described later.

  When the cooked rice division length control process is finished, the divided cooked rice R is weighed by the second weighing conveyor 5 (step S8).

  Then, it is determined whether or not the measured weight value (second measured weight value) of the cooked rice R by the second weighing conveyor 5 matches the target weight value (step S9). These series of operations are repeated for the quantity of sheet-like cooked rice R.

  If the measured weight value of the cooked rice R by the second weighing conveyor 5 does not match the target weight value in step S9, the transition portion predicted weight value is changed so that both values match (step S10). Then, the process returns to step S1, and a series of operations is repeated for the required quantity of cooked rice R.

  In the present embodiment, steps S8 to S10 correspond to the second control.

  Here, a case where the measured weight value of the cooked rice R is 95 g and the target weight value is 100 g is considered as an example of the case where the values do not match in step S9.

  As described above, since the measured weight value of the cooked rice R in step S6 is 90 g, if the measured weight value of the cooked rice R in step S9 is 95 g, the actual weight of the transition portion is 5 g. Therefore, in step S10, the predicted transition weight value is changed to 5g.

  Then, at the time of the next cooked rice division, when the measured weight value of the cooked rice R reaches 95 g in step S5, the sum of the measured weight value of the cooked rice R (95 g) and the predicted weight of the transition portion (5 g) is the target. Since the weight value (100 g) is reached, the cooked rice R is divided by the cutter 15 at the arrival timing in step S6. Thereby, the measured weight value of the cooked rice R in step S9 becomes 100 g, and the cooked rice R divided into the target weight is obtained.

  Thus, according to the cooked rice dividing apparatus M1 of the present embodiment, the cooked rice R is measured at the second speed after being transported at the first speed by the first weighing conveyor 4 while being decelerated to the second speed. The cooked rice R is obtained by dividing the cooked rice R when the weight value is obtained and the sum of the weight value and the predicted weight value of the transition portion reaches the target weight value, and the divided cooked rice R is measured by the second weighing conveyor 5. The predicted weight value of the transition part is changed based on the difference between the measured weight value and the target weight value.

  Accordingly, the cooked rice R can be quickly conveyed by the first weighing conveyor 4 at the first speed and can be quickly divided, and the second weighing conveyor 5 Since the value of the predicted weight value of the transition portion is changed based on the difference between the measured weight value of the measured cooked rice R and the target weight value, the sheet-shaped cooked rice R can be accurately divided by the target weight. Become.

  Next, the cooked rice division length control process (step S7) by the control unit 30 in the cooked rice dividing apparatus M1 of the present embodiment will be described.

  As described above, when the cooked rice R divided into a predetermined length is folded and formed into a shape such as a rice ball shape, for example, even if the weight of the cooked rice R is appropriate, the cooked rice R is longer than the specified length. If it is insufficient, a short portion of the cooked rice R will occur when folded, and it will not be formed into the desired shape, and the ingredients will be exposed without being wrapped. Further, if the cooked rice R is longer than the specified length, an excess portion of the cooked rice R is generated when it is folded, the cooked rice R becomes excessive locally, and similarly, it cannot be formed into a desired shape.

  The process for eliminating such inconvenience is the cooked rice division length control process in step S7.

  In the cooked rice division length control process, the control system shown in FIG. 5 is used. Therefore, the division length control of the cooked rice R will be specifically described with reference to the control system shown in FIG. 5 and the flowchart of FIG.

  In this process, first, the length of the divided cooked rice R (the portion indicated by the symbol L in FIG. 5) is measured (step S11). In the present embodiment, as described above, the length of the cooked rice R divided by the control unit 30 as a length measuring unit from the conveyance speed of the cooked rice R by the first weighing conveyor 4 and the division timing by the cutter 15. Is measured. The length may be measured using a separate sensor.

  Next, it is determined whether or not the length of the divided cooked rice R measured by the length measuring unit matches the target length of the divided cooked rice R (step S12). And the process proceeds to step S8 shown in FIG.

  On the other hand, if the lengths do not match, the length of the cooked rice R is adjusted to the target length by adjusting the thickness of the cooked rice R delivered from the delivery unit 6 based on the difference in length between the two. After that, the process proceeds to step S8 shown in FIG.

  That is, the fact that the length of the divided cooked rice R is short means that the thickness has increased, and therefore the thickness of the cooked rice R is adjusted to be thin. In addition, the fact that the length of the divided cooked rice R is long means that the thickness of the cooked rice R is thin, and therefore the thickness of the cooked rice R is adjusted to be thick.

  Here, the thickness of the cooked rice R can be adjusted specifically as follows.

  That is, the delivery unit 6 includes the first roller pair 13 that feeds the cooked rice R while compressing the cooked rice R downward from above, and the second roller pair 14 that adjusts the thickness of the cooked rice R. Therefore, the first roller The drive control of the pair 13 is performed, or the interval control of the second roller pair 14 is performed. Alternatively, both controls are performed.

  The drive control of the first roller pair 13 is executed by controlling the speed or torque of the first roller pair drive unit 33 that drives the first roller pair 13. If the speed of the torque or the torque is controlled so that the rice R is fed out quickly, the thickness becomes thick, and if it is slowly fed, the thickness becomes thin.

  Further, the interval control of the second roller pair 14 is executed by controlling the interval of the second roller pair 14 via the second roller pair moving unit 34. And if the space | interval of a roller is expanded, the thickness of the cooked rice R will become thick, and if it makes it narrow, thickness will become thin.

  The drive control of the first roller pair 13 and the interval control of the second roller pair 14 are performed according to data calculated in advance.

  In the present embodiment, steps S11 to S13 correspond to the fourth control.

  Thus, according to the cooked rice dividing apparatus M1 of the present embodiment, the length of cooked rice R is adjusted by adjusting the thickness of cooked rice R based on the difference between the actual length of the divided cooked rice R and the target length. Therefore, when the divided sheet-shaped cooked rice R is folded, there is no excess or deficiency in the length, and the desired shape can be formed.

  And the division | segmentation control and length control of the above-mentioned cooked rice R are performed simultaneously, and the molding (for example, rice ball) of appropriate weight and a shape can be obtained.

  In the above description, in the cooked rice split, the control unit 30 executes the first control and the second control described above, but the third control using the moving average instead of the second control. You may make it perform control.

  That is, the third control refers to the average value and the target weight value of the measured weight value (second measured weight value) of the most recent predetermined number of times (for example, three times) by the second weighing conveyor 5 of the divided cooked rice R. It is control which changes the value of a transition part prediction weight value based on a difference with.

  For example, if the last three measured weight values are 95 g, 96 g, and 97 g, respectively, the predicted value of the transition portion weight value is calculated based on the difference between the average value of 96 g and the target weight value (for example, 100 g). Change (in this case, change to 4g).

  If the first control and the third control are executed, the division control based on the average value is performed for each process, so the division control based on the average value calculated after the plurality of processes is performed. Compared with the case where it performs, the control responsiveness becomes favorable.

  Similarly, in the length adjustment of the divided cooked rice R, the control unit 30 executes the above-described fourth control, but instead of the fourth control, performs the fifth control using the moving average. You may make it perform.

  That is, the fifth control is a sending unit based on the difference between the average value of the most recent predetermined number of times (for example, three times) measured by the length measuring unit of the divided cooked rice R and the target length of the divided cooked rice R. 6 is a control for adjusting the thickness of the cooked rice R sent out from No. 6.

  If the fourth control is executed, the length control based on the average value is performed for each process, so when performing the length control based on the average value calculated after a plurality of processes. Compared to the control response, the control response is improved.
