  Hereinafter, an embodiment as an example of the present invention will be described in detail with reference to the drawings. 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 fixed-quantity cooked rice production apparatus (quantitative material lump production apparatus) M of the present embodiment has a first weighing conveyor (metering and conveying unit) 3 on a pedestal 2 that can be moved by a caster 1. A second weighing conveyor (metering and conveying unit) 4 and a payout conveyor 5 are arranged from the upstream side in the conveying direction to the downstream side.

  In addition, above the first weighing conveyor 3 and above the second weighing conveyor 4, sending sections 6, 7 for forming cooked rice (material) into a sheet shape and feeding them onto the weighing conveyors 3, 4 are arranged, respectively. ing.

  Furthermore, between the sending part 6 and the 1st weighing conveyor 3, the direction which cross | intersects the conveyance direction with the cooked rice R (FIG. 2) sent out from the sending part 6 (here, the direction substantially orthogonal to the conveyance direction). A cutter (dividing unit) 8 for generating a main weighing rice Rm (main material lump) having a predetermined length is arranged. The main weighing rice Rm divided and generated by the cutter 8 is placed on the first weighing conveyor 3.

  On the other hand, between the sending unit 7 and the second weighing conveyor 4, the cooked rice R fed from the sending unit 7 is divided in a direction intersecting the transport direction (here, a direction substantially orthogonal to the transport direction). A cutter (split unit) 9 for generating a predetermined length of cooked rice (hereinafter, the cooked rice sent from the feed unit 7 and divided by the cutter 9 is referred to as “supplemented weighed rice Rs (supplemented material lump)”) is disposed. ing. Then, the supplementary weighed rice Rs divided and generated by the cutter 9 is placed on the second weighing conveyor 4.

  The first weighing conveyor 3 and the second weighing conveyor 4 are provided with load cells 3a and 4a for weighing the weight of the cooked rice placed on the weighing conveyors 3 and 4, respectively.

  The first weighing conveyor 3, the load cell 3a, the delivery unit 6 and the cutter 8 constitute a first processing unit M1 (first processing means). The second weighing conveyor 4, the load cell 4a, the delivery unit 7 and the cutter 9 constitute a second processing unit M2 (second processing means).

  By such a fixed quantity cooked rice production apparatus M, the main cooked rice Rm is generated by dividing the continuous cooked rice R sent out from the feed section 6 by the cutter 8 and placed on the first weighing conveyor 3. . Then, the weight is transported while being weighed by the first weighing conveyor 3, and transferred to the second weighing conveyor 4.

  On the other hand, the continuous cooked rice R sent out from the delivery unit 7 is also divided by the cutter 9 so that the supplementary weighed rice Rs is generated, and the top of the main cooked rice Rm conveyed by the second weighing conveyor 4. It is put on. Then, the apparatus is moved from the second weighing conveyor 4 to the dispensing conveyor 5 to execute the next process (for example, for shaping the weighed cooked rice into a predetermined shape (for example, forming a triangular rice ball shape)). To the molding equipment).

  On the side of the pedestal 2 (on the right side in FIG. 1), there is provided a lifter 12 that raises and lowers the cooked rice container 11 along a pair of vertical rails 10 extending in the vertical direction. The lifter 12 lifts the cooked rice container 11 to the position of the hopper 13 installed at the top, and the flipper 14 provided at the upper end of the lifter 12 is turned upside down toward the hopper 13, thereby The cooked rice R is put into the hopper 13.

  The hopper 13 is provided so as to correspond to the sending unit 6 and the sending unit 7 described above. In the hopper 13, a first unrolling roller for unraveling the introduced cooked rice R, a conveying roller for conveying the uncooked rice R unrolled by the first unrolling roller to the sending unit 6 and the sending unit 7, A second unrolling roller (none of which is shown) is provided to further unwind the cooked rice R that has been conveyed to the conveying roller. Further, a branch plate 22 for branching the cooked rice R in the hopper 13 into the sending unit 6 and the sending unit 7 is installed at a boundary portion between the hopper 13 and the sending unit 6 and the sending unit 7. Therefore, the cooked rice R which has been unwound by the second unrolling roller is branched to the branch plate 22 and is introduced into the feeding section 6 and the feeding section 7 described above.

  An introduction roller 21 for introducing the cooked rice R from the hopper 13 is provided in the delivery unit 6. Further, below the introduction roller 21, a first roller pair 15 having a total of two pairs of left and right pairs is arranged in the vertical direction. In the first roller pair 15, the interval between the first roller pair 15b positioned at the lower stage is narrower than the interval between the first roller pair 15a positioned at the upper stage. Therefore, the cooked rice R is compressed and formed into a sheet shape by being sent downward from above by the first roller pair 15a, 15b.

  Further, below the first roller pair 15, a second roller pair 16 having a total of two stages in the left and right pair is arranged in the vertical direction. Here, the interval between the second roller pair 16 positioned below the interval between the first roller pair 15 is narrower. The second roller pair 16 can be moved closer to and away from each other.

  Therefore, the cooked rice R is fed while being compressed from above to below by the first roller pair 15. Then, by being sent to the second roller pair 16, it is further compressed and formed into a sheet shape. Since the second roller pair 16 can approach and separate from each other, the sheet-like continuous cooked rice R sent from the first roller pair 15 corresponds to the interval between the second roller pair 16. The thickness is adjusted to send out.

  In addition, a first roller pair 17 that is paired on the left and right is disposed in the delivery unit 7. Below the first roller pair 17, a second roller pair 18, which is a total of two stages in the left and right pair, is arranged in the vertical direction. Here, as in the delivery unit 6, the interval between the second roller pair 18 positioned below the interval between the first roller pair 17 is narrower. The second roller pair 18 can be moved closer to and away from each other.

  Therefore, the cooked rice R is sent while being compressed downward from above by the first roller pair 17 and is further compressed by being sent to the second roller pair 18 to be formed into a sheet shape. Then, the sheet-like continuous cooked rice R sent from the first roller pair 17 is sent out after the thickness is adjusted according to the distance between the second roller pair 18.

  On the side of the hopper 13 (on the left side in FIG. 1), the final target weight value T of the cooked rice, the set weight value Tm of the main weighed rice Rm, the allowable weight value of the main weighed rice Rm and the supplementary weighed rice Rs, etc. And an operation switch 20 for driving and stopping the fixed-quantity cooked rice production apparatus M are provided. Therefore, the operator measures the cooked rice by the quantitative cooked rice production apparatus M by appropriately operating the operation panel 19 and the operation switch 20.

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

  In FIG. 2, the operation | movement of the fixed-quantity cooked rice manufacturing apparatus M is controlled by the 1st control part 31 (control means) and the 2nd control part 32 (control means). A first weight detector 33 is connected to the first controller 31, and the weight of the main weighed rice Rm measured by the load cell 3 a and detected by the first weight detector 33 is input. In addition, a first weight detector 33 and a second weight detector 34 are connected to the second control unit 32, and the main weight measured by the load cell 3 a and detected by the first weight detector 33. The weight of the rice Rm and the total weight W of the main weighed rice Rm and the supplementary weighed rice Rs measured by the load cell 4a and detected by the second weight detector 34 are input. In the present embodiment, the first control unit 31 and the second control unit 32 are separated, but the control units 31 and 32 may be integrated.

  In the first processing unit M1, the main weighing rice Rm is generated by using the operation panel 19 described above, with the set weight value Tm set to a weight smaller than the final target weight value T of the rice to be weighed. Is set. And the 1st control part 31 produces | generates the main measurement rice Rm which correct | amended the weight difference of the weight of the actual main measurement rice Rm measured by the load cell 3a of the 1st process part M1, and the setting weight value Tm. In this manner, the first processing unit M1 is controlled (first control / feedback control).

  In addition, the second control unit 32 replenishes the replenishment weight value Ts, which is a weight difference between the weight of the main weighed rice Rm measured by the load cell 3a of the first processing unit M1 and the final target weight value T, as a target. The second processing unit M2 is controlled so as to generate the weighing rice Rs (second control / feedforward control).

  Furthermore, the second control unit 32 corrects the weight difference between the weight of the supplementary weighing rice Rs obtained from the weight measured by the load cell 4a of the second processing unit M2 and the supplementary weight value Ts, and the supplementary weighing rice Rs. The second processing unit M2 is controlled so as to generate (third control / feedback control).

  In the present embodiment, the first control unit 31 obtains a deviation between the weight of the main weighed rice Rm measured by the load cell 3a of the first processing unit M1 and the set weight value Tm, and the deviation is determined in advance. The first control is executed when the set allowable range is not reached. Further, the second control unit 32 obtains a deviation between the weight of the supplementary weighing rice Rs and the supplementary weight value Ts from the weight measured by the load cell 4a of the second processing unit M2, and the deviation is set in advance. When it is out of range, the third control is executed.

  Here, the first control unit 31 and the second control unit 32 control the drive of the first roller pair 16, 18, the distance control of the second roller pair 16, 18, and the operation timing of the cutters 8, 9. Control is in progress. Then, the weight of the main weighing rice Rm or the supplementary weighing rice Rs in the first control, the second control, and the third control is adjusted by executing any or all of these controls. The drive control of the first roller pair 16, 18 is executed by controlling the speed or torque of a motor (not shown) that drives the first roller pair 16, 18.

  However, the control units 31 and 32 do not necessarily need to perform these three types of control, and may perform at least any one control. Moreover, you may adjust the weight of the main measurement rice Rm and the supplementary measurement rice Rs by other than these control.

  Next, weight control by the first control unit 31 and the second control unit 32 of the quantitative cooked rice production apparatus M of the present embodiment will be specifically described with reference to the flowcharts of FIGS.

  The cooked rice R is put into the hopper 13, the second roller pair 16 of the delivery unit 6 is set at a predetermined interval, and the first roller pair 15 starts rotating, and the first weighing conveyor 3 and the second weighing machine 3 are turned on. The conveyor 4 starts moving around. In FIG. 3, the first control unit 31 sends out the continuous cooked rice R molded into a sheet form from the delivery unit 6, and the main cooked rice Rm is generated by being divided by the cutter 8 (step S <b> 1). .

  Here, when the final target weight value T is set to 100 g, for example, in step S1, the main weighed rice Rm is generated so as to target a weight (for example, 95 g) smaller than 100 g which is the final target weight value T. A set weight value Tm is set. This setting is performed on the operation panel 19 described above.

  The generated main weighing rice Rm is placed on the first weighing conveyor 3, and the weight Wm of the main weighing rice Rm is weighed (step S2) and conveyed by the load cell 3a. The measurement result is sent to the first control unit 31 and the second control unit 32. The measurement result here is 90 g, for example.

  Next, in response to the measurement result, the second control unit 32 calculates a replenishment weight value Ts (= T−Wm) (step S3). That is, since the final target weight value T is 100 g and the weight Wm of the generated main weighed rice Rm is 90 g, 10 g is calculated as the supplementary weight value Ts here.

  When the supplementary weight value Ts is calculated in this way, the supplementary weighed rice Rs targeting the weight value Ts is generated by the second control unit 32 (step S4). That is, the second roller pair 18 of the delivery unit 7 is set at a predetermined interval, and the first roller pair 17 starts to rotate. Then, the cooked rice R is delivered from the delivery unit 7 and divided by the cutter 9 to generate a supplementary weighed rice Rs targeting 10 g which is the supplementary weight value Ts. The generated supplementary weighing rice Rs is supplemented on the main weighing rice Rm flowing from the first weighing conveyor 3 to the second weighing conveyor 4.

  The total weight W of the main weighing rice Rm on the second weighing conveyor 4 supplemented with the supplementary weighing rice Rs is weighed by the load cell 4a (step S5). The measurement result is sent to the second control unit 32.

  And in step S6, when operation | movement of the fixed-quantity cooked rice manufacturing apparatus M stops, it complete | finishes as it is, and when not stopping, it transfers to the following step.

  In the present embodiment, steps S2 to S4 correspond to the second control.

  When the operation of the fixed-quantity cooked rice production apparatus M does not stop in step S6, the main weighing correction amount determination process (step S7) and the supplementary weighing correction amount determination process (step S8) are executed, and then the main metering process described above is performed. The process returns to the generation of the weighing rice Rm (step S1).

  The main metric correction amount determination process (step S7) will be described with reference to FIG.

  In the process, first measurement deviation Sm (= Wm−Tm) is first calculated in the first control unit 31 (step S71). That is, the main weighing deviation Sm is calculated by subtracting the set weight value Tm from the weight Wm of the main weighing rice Rm weighed immediately before. Since the weight Wm here is 90 g and the set weight value Tm is 95 g, the main weighing deviation Sm is −5 g.

  In addition, in the present embodiment, processing is performed using deviations, including processing for determining the supplemental weighing correction amount described below. However, the average value of weights Wm and Ws measured multiple times and the set weight value Tm, You may process using the difference with the replenishment weight value Ts.

Now, if the main measurement deviation Sm is calculated in step S71, it is determined whether or not the main measurement deviation Sm is within a preset allowable range. Prior to the determination, the main weighing weight plus side allowable value Dm ⁺ and the main weighing weight minus side tolerance value Dm ⁻ are set. This setting is also performed on the operation panel 19 described above. Here, main metering weight plus side tolerance Dm ^+, for example + 3 g, main metering weight minus side allowable value Dm ^- and it is set to, for example, 3 g.

Now, the process proceeds to step S72, the main metering deviation Sm whether main metering weight plus side tolerance Dm ⁺ or is determined, main metering weight plus side tolerance Dm ⁺ the processing proceeds to step S73 if so The negative correction is performed so that the main weighing correction amount determination process is completed.

In the case of the present embodiment, the main weighing deviation Sm is −5 g in step S72, and the main weighing deviation Sm is not greater than the main weighing weight plus side allowable value Dm ^+. Therefore, the process does not proceed to step S73 but step S74. proceeds to the main metering deviation Sm is main metering weight minus side allowable value Dm ^- whether the following is determined. Here, since the main weighing deviation Sm is −5 g and the main weighing weight minus side allowable value Dm ⁻ is −3 g, the routine proceeds to step S75 so that the main weighing weight minus side allowable value Dm ^{− is} within the main weighing weight minus side allowable value Dm ⁻ . The positive correction is made and the determination processing of the main metric correction amount ends. In this embodiment, including the above-described minus correction, the weight is corrected to be the set weight value Tm. However, it is sufficient if the weight value is within the allowable range.

The main metering deviation Sm in step S74 is main metering weight minus side allowable value Dm ^- if not even more, the determination process in the main metering correction amount without being corrected by the migration is completed to step S76.

  The main metric correction amount determination process corresponds to the first control.

  Next, the replenishment weighing correction amount determination process (step S8) will be described with reference to FIG.

  In this process, the second control unit 32 first calculates the weight Ws (= W−Wm) of the supplementary weighed rice Rs (step S81). As described above, since the weighing result of the weight Wm of the main weighing rice Rm in step S2 and the weighing result of the total weight W in step S5 are sent to the second control unit 32, in the second control unit 32, The weight Wm of the supplementary weighed rice Rs is calculated by subtracting the weight Wm of the main weighed rice Rm from the total weight W. Here, assuming that the total weight W is, for example, 101 g, the weight Wm of the main weighed rice Rm is 90 g as described above, so the weight Ws of the supplementary weighed rice Rs is 11 g.

  Next, the replenishment weighing deviation Ss (= Ws−Ts) is calculated from the weight Ws of the replenishment weighing rice Rs thus calculated (step S82). That is, the replenishment weighing deviation Ss is calculated by subtracting the replenishment weight value Ts calculated in step S3 from the weight Ws of the replenishment weighing rice Rs. Here, since the weight Ws of the replenished weighed rice Rs is 11 g and the replenished weight value Ts is 10 g, the replenished weighing deviation Ss is +1 g.

If the replenishment weighing deviation Ss is calculated in step S82, it is determined whether or not the replenishment weighing deviation Ss is within a preset allowable range. Prior to the determination, a supplementary weighing weight plus side allowable value Ds ⁺ and a supplementary weighing weight minus side tolerance value Ds ⁻ are set. This setting is also performed on the operation panel 19 described above. Here, supplemented weighed weight plus side tolerance Ds ^+, for example + 1 g, replenishing the weighing weight minus side allowable value Ds ^- and is set to, for example -1g.

Now, the process proceeds to step S83, the replenishment weighing deviation Ss whether supplementation weighing weight plus side tolerance Ds ⁺ or is determined, supplemented weighed weight plus side tolerance Ds ⁺ the processing proceeds to step S84 if so Thus, the supplementary weighing correction amount determination process is completed.

In the present embodiment, the replenishment weighing deviation Ss is +1 g in step S83 and the replenishment weighing deviation Ss is equal to or greater than the replenishment weighing weight plus allowable value Ds ^+. The negative correction is made so as to be within the permissible value Ds ⁺ , and the process for determining the supplemental weighing correction amount is completed.

  In addition, in this embodiment, including the case of plus correction described later, correction is made so that the replenishment weight value Ts is obtained. However, it is sufficient if the weight value is within the allowable range.

Here, when replenishing the weighing deviation Ss is not supplemented weighing weight plus side tolerance Ds ⁺ or higher at step S83, the proceeds to step S85, the replenishment weighing deviation Ss is supplemented weighing weight minus side allowable value Ds ^- whether following To be judged. If the replenishment weighing deviation Ss is equal to or smaller than the replenishment weighing weight minus allowable value Ds ⁻ , the process proceeds to step S86 and is positively corrected so as to be within the replenishment weighing weight minus allowable value Ds ⁻ . The determination process ends.

Furthermore, refill the weighing deviation Ss in step S85 is supplemented weighing weight minus side allowable value Ds ^- if not even more, the determination process of replenishing the weighing correction amount without being corrected by the migration is completed to step S87.

  The process for determining the supplemental weighing correction amount corresponds to the third control.

  Thus, according to the fixed-quantity cooked rice manufacturing apparatus M of this Embodiment, the main measurement which correct | amended the weight difference of the weight of the actual main measurement rice Rm measured by the 1st process part M1 and the setting weight value Tm. The first control as the feedback control for generating the rice Rm, and the replenishment weight value Ts that is the weight difference between the weight of the main measurement rice Rm measured by the first processing unit M1 and the final target weight value T is set as a target. The second control as feed-forward control for generating the replenished weighed rice Rs is executed, and the replenished weighed rice Rs is replenished to the main weighed rice Rm. It becomes possible to measure.

  Further, a third control as feedback control for generating the supplementary weighed rice Rs in which the weight difference between the weight of the supplementary weighed rice Rs obtained from the weight weighed by the second processing unit M2 and the supplementary weight value Ts is corrected. Therefore, it is possible to measure a mass of material such as cooked rice with a target weight with higher accuracy.

  In the present invention, the third control executed in the above description is not essential. And in the fixed-quantity cooked rice manufacturing apparatus M in which the third control is not executed, the load cell 4a of the second processing unit M2, the second weight detector 34, and the second weight detector 34 to the second There may be no feedback control system reaching the control unit 32. Therefore, instead of the second weighing conveyor 4 as the weighing and conveying unit, a conveyor as a conveying unit that conveys the main weighing rice Rm sent from the first weighing conveyor 3 and supplemented with the supplemented weighing rice Rs. Used.

  Further, the shapes of the main weighing rice Rm and the supplementary weighing rice Rs can be freely set, and are not limited to the sheet shape.
