Abstract

PROBLEM TO BE SOLVED: To enable operators to easily recognize the quality related to a deviation from a target value of the weight or number of products which are sorted by weight ranks and added up in a batch.SOLUTION: At least one of the total values of the weight and number of products 14, the weight rank of which has been identified, is determined whether or not it has reached at least one of respective target values for the total weight and total number of the products set by an input part 11, and also the deviation degree of the total value from the target value is determined based on a permissible value to notify operators using an LED in a notification part 15. Thus, the operators can recognize whether or not the weight or number of products sorted into a sorting position of a sorting device 5 and added up in a batch has reached the target value, and also recognize how much the weight or number of products added up in the batch is deviated from the target value on the basis of the permissible value.

Description

  The present invention relates to a weight sorter that sorts a weighed article for each predetermined weight rank, and more particularly to a quality display of articles sorted and aggregated for each weight rank.

  For example, goods of the same type such as agricultural and fishery products are sorted into a plurality of weight ranks, and the total weight of the sorted articles of each weight rank is counted and packed in a box. There is a case where traded goods are traded as a product unit.

  In such a case, a weight sorter is used, and the weight sorter sequentially measures the weight of the article, and determines which weight rank belongs to a plurality of preset weight ranks. To do. Each article whose weight rank is determined is sorted at a plurality of sorting positions predetermined for each weight rank, and is stored in a container of each weight rank arranged at each sorting position.

  Then, when the total weight of the articles of the weight rank distributed to the storage container reaches a predetermined target weight, the fact that the counting has been completed is displayed on the display unit or the like, and the operator knows that the counting has been completed. The storage container in which the article is stored is replaced with a new container (see, for example, Patent Documents 1 and 2).

Japanese Patent No. 4112074 Japanese Patent Publication No. 8-18013

  As described above, in each container, the total weight of articles of each weight rank is so-called batch-counted every time a predetermined target weight is reached. Even so, due to the bias in the weight of the goods from time to time, and the delay in taking out the aggregated goods, the deviation between the total weight of the batch-aggregated articles and the predetermined target weight is increased, May cause a difference in the number of articles to be batched.

  In the conventional example such as Patent Document 1 described above, the total weight of the articles of a certain weight rank has reached a predetermined target weight, and only the notification that the aggregation has been completed is provided. The total weight and the quality of the total number, such as how far from a predetermined target weight, or the number of articles, is not notified at all.

  For this reason, for example, when determining the quality related to the deviation from the target value such as the total weight of the articles collected in batches in the storage container and packing the boxes for each quality rank, the operator determines the quality. There is a problem that the work is troublesome and the quality judgment varies.

  The present invention has been made in view of the above points, and enables an operator to easily grasp the quality of the weight and the number of articles selected for each weight rank and batch-counted. For the purpose.

  In order to achieve the above object, the present invention is configured as follows.

(1) The weight sorter of the present invention measures an article, determines which of the plurality of weight ranks the article belongs to, and corresponds to the determined weight rank among the plurality of distribution positions. A weight sorter that sorts the article into a sorting position,
A target value of at least one of the total weight and the total number of the articles according to the weight rank distributed to each distribution position is set, and at least one of the total weight and the total number of the set target values A setting unit in which an allowable value is set, and
A totaling unit that counts at least one of the weight and the number of the articles for which the weight rank is determined;
Of the target values set by the setting unit, based on the target value of at least one of the total weight and the total number of the articles, and the total value calculated by the total unit corresponding to the target value A determination unit that determines whether or not the total value has reached the target value, and that determines a degree of deviation of the total value from the target value based on the allowable value set by the setting unit; ,
A notifying unit for notifying a determination result of whether or not the target value determined by the determining unit has been reached, and notifying a determination result of the degree of deviation for each weight rank;

  For the target value, the setting unit may set only the target value of the total weight, or may set only the target value of the total number, or the target value of the total weight And the total number of target values may be set together.

  When the setting unit is to set only the target value of the total weight as described above, it is sufficient to set an allowable value for the target value, and only the target value of the total number is set. In this case, it suffices to set an allowable value for the target value. When the target value for the total weight and the target value for the total number are set together, at least one of the target values is set. What is necessary is just to set an allowable value for the target value. The allowable value for the target value is not limited to one and may be plural.

  The determination unit determines whether or not the total value has reached the target value, but this determination is not necessarily performed for all target values set by the setting unit. That is, when both the total weight and the total number of target values are set by the setting unit, the determination unit may determine only whether or not the total weight value has reached the total weight target value. However, it may be determined only whether the total value of the number has reached the target value of the total number, or both the total value of the weight and the number are respectively set to the target value of the total weight and the total number. It may be determined whether it has been reached.

  It is preferable to determine whether or not the degree of deviation determined by the determination unit is a degree of deviation compared to an allowable value, for example, whether the deviation is within an allowable range based on the allowable value. Further, the deviation means at least one of a deviation in the plus (positive) direction and a deviation in the minus (negative) direction of the total value with respect to the target value.

  The notification unit only needs to be able to notify the determination result of whether or not the target value has been reached and the determination result of the degree of deviation. For example, the notification unit may notify by the lighting state of the indicator lamp or the display of the display unit, You may notify by printing, and you may make it alert | report combining them.

  The notification unit may separately notify the determination result whether the target value has been reached and the determination result of the degree of deviation, but may notify the determination result whether the target value has been reached. For example, if the determination result of the degree of deviation is notified on the condition that the target value has been reached, the degree of deviation may be notified. By doing so, it can be notified that the target value has been reached indirectly.

  According to the weight sorter of the present invention, the total value of at least one of the weight and the number of articles whose weight rank is determined has reached the target value of at least one of the set total weight and total number of articles. And determining and reporting the degree of deviation of the total value with respect to the target value based on the allowable value, so that the operator can distribute the batches of articles that are distributed to each distribution position. It is possible to grasp whether the weight and number have reached the target value, and to know how much the weight and number of articles to be batched deviate from the target value based on the allowable value. For example, batch counting Assuming that the aggregate value of the weights of the selected articles has reached the target value of the total weight, it is possible to grasp the completion of batch aggregation, and the deviation of the aggregate value from the target value is allowed based on the allowable value. Can grasp that such whether the range. That is, it is possible to grasp the quality related to the deviation from the target value for the weight and the number of articles according to weight rank that are distributed to the respective distribution positions and batch-collected. Therefore, it becomes easy to classify the articles according to the weight ranks that have reached the target value and are tabulated and classified according to quality.

  (2) In a preferred embodiment of the weight sorter according to the present invention, both the total weight and the total number of target values are set in the setting unit, and the totaling unit is configured to determine the weight of the article by weight rank. And the determination unit is set by the setting unit and a total value of at least one of the total values of the weight and the number of the articles by weight rank, which are respectively totaled by the total unit. Based on at least one target value of the two target values, it is determined whether or not one of the total values has reached one of the target values.

  The allowable value may be set only for the target value of the total weight, may be set only for the target value of the total number, or may be set for both target values of the total weight and the total number. .

  When it is determined that either one of the aggregate values of the weight and number of articles to be aggregated in the aggregation section has reached one of the corresponding target values, the required quantity of articles is placed in the distribution position. Batch aggregation may be completed after distribution, and when it is determined that both the aggregate values have reached both target values, the required amount of articles is allocated to the allocation position and batch aggregation is completed. Also good.

  According to this embodiment, at least one of the total values of the weight and the number of the articles whose weight rank is determined is at least one of the set target values of the total weight and the total number of the articles. It is determined whether or not the target value has been reached, and the degree of deviation of the total value with respect to the target value is determined and notified based on an allowable value, so that the worker is distributed to each distribution position and batch Based on whether or not the aggregate value of at least one of the weight and number of articles to be aggregated has reached the corresponding target value, it is possible to grasp whether or not batch aggregation has been completed, and based on the allowable value It is possible to grasp how much the aggregate value deviates from the target value, and to easily grasp the quality related to the deviation from the target value for the weight and number of articles collected in batch. It can become.

  (3) In the embodiment of (2), the determination unit outputs the determination result of the degree of deviation for the determined weight and the determination result of the degree of deviation for the number to the notification unit, respectively. The notification unit may notify each determination result of the degree of deviation of the weight and the number of pieces.

 According to this embodiment, the operator can individually grasp the quality related to the deviation from the target value for the weight of the articles collected in batches and the quality related to the deviation from the target value for the number of pieces. It is possible to judge the quality as a whole with emphasis or to judge the quality as a whole with emphasis on the number.

  (4) In the embodiment of the above (2), the determination unit determines that the article distributed to the distribution position in advance when any one of the total values reaches the one target value, It is determined which of the plurality of quality ranks determined according to the degree of deviation belongs to the quality rank, and the notification unit is configured to determine the plurality of quality based on the determination result of the degree of deviation of the determination unit. You may make it alert | report according to which weight rank it corresponds to which quality rank of a rank.

  According to this embodiment, when the total value of at least one of the total values of the weight and the number reaches the target value of at least one of the total values of the total weight and the total number, it is distributed to the distribution position. In addition, since it is informed which quality rank of the plurality of quality ranks determined in advance according to the degree of deviation, the worker is assigned to each sorting position and batched The quality rank can be immediately grasped.

  (5) In a preferred embodiment of the weight sorter according to the present invention, the notification unit includes a plurality of display units respectively arranged corresponding to the distribution positions.

  According to this embodiment, each display unit arranged at each distribution position visually checks the quality related to the deviation from the target value for the weight and number of articles by weight rank that are distributed to each distribution position and tabulated. It can be easily grasped.

  According to the present invention, it is possible to easily grasp the quality related to the deviation from the target value for the weight and number of articles according to the weight rank distributed to each distribution position and totaled in batches. It becomes easy to classify articles by weight rank according to quality and pack them.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram of a weight sorter according to an embodiment of the present invention.

  The weight sorter according to this embodiment includes a feeding conveyor 1 to which articles 14 are sequentially supplied, a weighing conveyor 2 for weighing the articles 14 fed from the feeding conveyor 1 while being weighed, and a weighing conveyor 2. The delivery conveyor 4 which conveys the articles | goods 14 and the distribution apparatus 5 which distributes the articles | goods 14 in each distribution position corresponding to a some weight rank are provided.

The weighing conveyor 2 is supported by a load detector 3 such as a load cell. Between the metering conveyor 2 and preceding infeed conveyor 1, an article detecting photosensor PH ₁ is provided for, distributed to device 5 also, a plurality of photosensors PH ₂₁ so as to correspond to the distribution position , PH ₂₂ ,... PH _2n are provided.

  This weight sorter includes an amplifier 6 that amplifies an analog load signal from the load detector 3, an A / D converter 7 that converts the analog load signal into a digital load signal, and an input / output circuit (I / O) 8; In addition to controlling each part, the weight rank is determined based on the measured value of the article 14, the weight and the number are counted for each weight rank, and a control program and a plurality of weight ranks are defined for determination processing described later. A storage unit 10 such as a ROM or a RAM for storing set values such as boundary values to be stored or temporarily storing data during calculation, an input unit 11 such as a keyboard, and a display device 20 such as a liquid crystal display. Yes.

  The input unit 11 as a setting unit can set and input information necessary for operation and operation of the weight sorter, for example, information such as boundary values that define a plurality of weight ranks. It is possible to set and input the total weight of the articles to be processed, the target value of the total number, and the like. The display device 20 can display a set value, a weight value of the article 14, total data, and the like.

In the weight sorter of this embodiment, the article 14 supplied to the infeed conveyor 1 shields the photosensor PH ₁ at a position immediately before the weighing conveyor 2. At this time, the output pulse of the photosensor PH ₁ is input to the CPU 9 via the input / output circuit 8. Then, when the article 14 is transferred onto the weighing conveyor 2, the load detector 3 outputs an analog load signal corresponding to the article 14. This analog load signal is amplified by the amplifier 6 and converted into a digital load signal by the A / D converter 7. Then, when a predetermined stabilization time has elapsed since the output pulse of the photosensor PH ₁ is input to the CPU 9, the CPU 9 obtains the measurement value of the article 14, and to which weight rank of the plurality of weight ranks the measurement value is. It is determined whether it belongs, and the determination result is sent to the distribution device 5 as a distribution signal.

  The article 14 having been weighed is conveyed to the sorting device 5 through the weighing conveyor 2 and the delivery conveyor 4. The sorting device 5 drives an actuator (not shown) to incline a reject conveyor (not shown) when the sent article 14 shields the photosensor corresponding to the weight rank of the article 14, and this weight The ranked article 14 is discharged out of the conveyance path at the sorting position corresponding to the weight rank. A storage container (not shown) for storing the discharged article 14 is disposed at each distribution position, and the article 14 discharged to the outside of the conveyance path is stored in the storage container.

The distribution device 5 includes a plurality of photosensors PH ₂₁ , PH ₂₂ ,... PH _2n corresponding to the weight rank, and a plurality of tiltable reject conveyors so as to face the discharge end of each reject conveyor. In addition, a plurality of storage containers for storing the article 14 are arranged.

  The distribution device 5 is controlled by the CPU 9 and distributes the articles 14 whose weight rank is determined to the storage containers corresponding to the determined weight rank.

The weight sorter also provides a plurality of notifications for notifying that the total weight or total number of articles 14 by weight rank stored in each storage container has reached a preset target value, as will be described later. Parts 15 ₁ to 15 _n are provided.

The plurality of notification units 15 ₁ to 15 _n are installed in close proximity to the corresponding storage containers. As shown in FIG. 2, each of the notification units 15 ₁ to 15 _n turns off the four different color LEDs 21 to 24 and all the LEDs 21 to 24 and resets the counting process and the like. 25. In this example, a green LED 21 and a blue LED 22 for displaying the total number of articles 14 stored in the storage container are provided, and a yellow LED 23 and a red LED 24 for displaying the total weight of the articles 14 stored in the storage container 14 are provided. It has. The notification units 15 ₁ to 15 _n are controlled by the CPU 9 via the input / output circuit 8.

  In this embodiment, the total weight and the total number of articles by weight rank distributed to each distribution position and stored in each storage container are notified that the target value has been reached, and the total weight with respect to the target value. In order to notify how much the total number is deviated, it is configured as follows.

  That is, in the input unit 11 as a setting unit, the target value of the total weight and the total number of articles stored in the storage container is set for each weight rank, and an allowable value for at least one target value of each target value is set. Further, a setting for selecting any one of a plurality of determination patterns such as a quality determination condition registered in advance is performed.

  The CPU 9 weighs the articles 14 to determine the weight rank, controls the distribution device 5, and distributes the articles 14 to the respective storage containers at distribution positions corresponding to the weight ranks. Further, the CPU 9 sums up the weight and the number of the articles 14 for which the weight rank is determined for each weight rank, and is stored in each storage container based on the target value and the allowable value set by the input unit 11. The quality of the weight and the number of the articles 14 is determined, and the determination result is notified by each notification unit 15.

  In this embodiment, a plurality of first to fourth specifications are registered in advance in the storage unit 10 as the plurality of determination patterns, and any one of the specifications is selected by operating the input unit 11.

  Hereinafter, processing when each specification is selected will be described.

<First specification>
A case where the first specification is selected will be described.

  FIG. 3 is a process common to each specification. First, when the article 14 is transferred onto the weighing conveyor 2, the load detector 3 outputs an analog load signal, is converted into a digital load signal by the A / D converter 7, and is input to the CPU 9 (step S11). ). The digital load signal input to the CPU 9 is converted into an article weight value Wx (step S12).

  The article weight value Wx is compared with boundary values of a plurality of weight ranks to determine which weight rank it belongs to (step S13), the distribution device 5 is controlled, and the distribution position corresponding to the determined weight rank The articles 14 are sorted by

  Next, the number Ci of the articles 14 having the determined weight rank is incremented. That is, the number of articles 14 having the determined weight rank is tabulated (step S14).

  Further, the article weight value Wx is added to the total weight value ΣWi of the determined weight rank to obtain a new total weight value. That is, the weight values of the determined weight rank are totaled (step S15).

  Next, the process proceeds to a process corresponding to the selected specification (step S16). Here, since the first specification is selected, the process proceeds to the process of the flowchart of FIG.

  Table 1 corresponds to the processing of the flowchart of FIG. 4, and shows the state of the total number of articles Px and the total weight Wtx, and the lighting state of the green and yellow LEDs 21 and 23 of the notification unit 15. Is shown.

この表１及び図４において、Ｐｏ及びＷｔｏは、入力部１１で設定される合計個数及び合計重量の各目標値である。αは、入力部１１で設定される目標値Ｗｔｏについての許容値であり、この許容値αは、例えば、１未満の任意の値であり、本例では、例えば、α＝０．０１とする。

In Table 1 and FIG. 4, Po and Wto are target values of the total number and total weight set by the input unit 11. α is an allowable value for the target value Wto set by the input unit 11, and the allowable value α is, for example, an arbitrary value less than 1, and in this example, for example, α = 0.01. .

  As shown in Table 1, the first specification prescribes the quality ranks A to D with priority on the total number Px, and prioritizes that the total number Px matches the target value Po of the total number. To do.

  As shown in FIG. 4, for the weight rank determined in step S13, it is determined whether or not the total number Px is smaller than the target value Po of the number set in the input unit 11 (step S21). When the total number Px is smaller than the target value Po, the process ends and the totaling is continued.

  When the total number Px is not smaller than the target value Po in S21, the process proceeds to step S22, and it is determined whether or not the total number Px = the target value Po. When the total number Px = the target value Po, the process proceeds to step S23, and the green LED 21 for displaying the total number of the notification unit 15 corresponding to the weight rank is turned on.

  When the total number Px is not equal to the target value Po in S22, the total number Px> the target value Po, the process proceeds to step S24, and the green LED 21 is flashed.

  In S25, it is determined whether or not the total weight Wtx is greater than or equal to the weight target value Wto set by the input unit 11. When the total weight Wtx is not equal to or greater than the target value Wto, the process ends and the counting is continued.

  When the total weight Wtx is greater than or equal to the target value Wto in S25, the process proceeds to step S26, where the total weight Wtx is within an allowable range in which an upper limit is defined by the weight allowable value α set by the input unit 11 (Wto ≦ It is determined whether or not Wtx ≦ (1 + α) · Wto).

  When the total weight Wtx is within the allowable range in S26 (Wto ≦ Wtx ≦ (1 + α) · Wto), the process proceeds to step S27, and the yellow LED 23 for displaying the total weight of the notification unit 15 corresponding to the weight rank is turned on. finish.

  If the total weight Wtx is not within the allowable range in S26 (Wtx> (1 + α) · Wto), the process proceeds to step S28, and the yellow LED 23 is flashed and the process ends.

  By the above processing, when both the LEDs 21 and 23 of the green LED 21 for displaying the total number of the notification unit 15 and the yellow LED 23 for displaying the total weight are in a lighting state of lighting or flashing lighting, the totaling is performed. Since both the number and the weight have reached the target value, the worker can store the article 14 of the weight rank, assuming that the batch counting is completed when both the LEDs 21 and 23 are turned on. Replace the stored container with a new one.

  When the batch counting is completed, the operator can count the total number of articles 14 stored in the storage container as shown in Table 1 when the green LED 21 for displaying the total number is continuously lit not flashing. It can be understood that Px matches the target value Po, and when the green LED 21 is flashed, it can be understood that the total number Px exceeds the target value Po. .

  Further, when the batch counting is completed, the operator can sum up the articles 14 stored in the storage container as shown in Table 1 when the yellow LED 23 for displaying the total weight is continuously lit not flashing. It is possible to grasp that the weight Wtx is within an allowable range (Wto ≦ Wtx ≦ (1 + α) · Wto) equal to or greater than the target value Wto, and when the yellow LED 23 is flashed, the total summed up It can be understood that the weight Wtx exceeds the allowable range (Wtx> (1 + α) · Wto).

  In this way, the operator can grasp that the batch counting has been completed based on the lighting state of the green LED 21 for displaying the total number and the yellow LED 23 for displaying the total weight, and also the batch total storage container. It is possible to grasp which quality rank of the article 14 is A, B, C, or D shown in Table 1. Thus, the worker can easily sort the storage containers in which the articles 14 are stored into the quality ranks A, B, C, and D, and can pack them for each quality rank.

  The quality rank D in which the total number Px exceeds the target value Po and the total weight Wtx exceeds the allowable range, for example, allows the operator to change the container even though the batch total has been completed. This includes cases where batch counting is continued after a delay.

  After the batch counting is completed, the operator grasps the quality rank and replaces the storage container, the operator operates the reset button 25 of the notification unit 15 to reset the batch counting, and thereby the weight rank is While starting a new batch count, the LEDs 21 and 23 are turned off.

  It should be noted that a label or the like indicating the relationship between the quality ranks A to D and the lighting states of the LEDs 21 and 23 may be attached to the notification unit 15 so that the operator can easily confirm the label, or the notification unit 15 You may display by providing a display part. Alternatively, as described later, an LED for each quality rank may be provided, and the corresponding quality rank LED may be turned on to directly display the quality rank.

  Moreover, you may make it perform the replacement | exchange of the container which batch collection was completed automatically.

<Second specification>
Next, a case where the second specification is selected will be described.

  FIG. 5 is a flowchart showing the process of the second specification, and Table 2 shows the status of the total number Px and the total weight Wtx corresponding to the process of FIG. 23 shows a lighting state and the like.

この第２の仕様は、表２に示すように、集計される合計重量Ｗｔｘを優先して品質ランクＡ〜Ｄを規定するものであり、合計重量Ｗｔｘが、目標値Ｗｔｏ以上の許容範囲内（Ｗｔｏ≦Ｗｔｘ≦（１＋α）・Ｗｔｏ）にあることを優先するものである。

As shown in Table 2, this second specification prescribes the quality ranks A to D in preference to the total weight Wtx that is tabulated, and the total weight Wtx is within an allowable range equal to or greater than the target value Wto ( (Wto ≦ Wtx ≦ (1 + α) · Wto).

  In the second specification, as shown in FIG. 5, it is first determined whether or not the total weight Wtx to be totalized is smaller than the target value Wto of the total weight (step S41). Continue.

  If the total weight Wtx is not smaller than the target value Wto in S41, the process proceeds to step S42, where the total weight Wtx is within an allowable range in which an upper limit is defined by the allowable value α of weight (Wto ≦ Wtx ≦ (1 + α) · Wto ) Or not. When the total weight Wtx is within the allowable range, the process proceeds to step S43, the yellow LED 23 is turned on, and the process proceeds to step S45.

  When the total weight Wtx is not within the allowable range in S42 (Wtx> (1 + α) · Wto), the process proceeds to step S44, the yellow LED 23 is flashed and the process proceeds to step S46.

  In step S45, it is determined whether or not the total number Px is equal to or greater than the target value Po of the number. If the total number Px is not equal to or greater than the target value Po, the process is terminated and the total is continued.

  When the total number Px is equal to or larger than the target value Po in S45, the process proceeds to step S47, and whether the total number Px is within the allowable range in which the upper limit is defined by the allowable value α (Po ≦ Px ≦ (1 + α) · Po). Judge whether or not. In this example, the allowable value α is the same as the above-described allowable value α of the weight value. Different allowable values may be used for the total weight value and the total number. When the total number Px is within the allowable range, the process proceeds to step S50, the green LED 21 is turned on, and the process ends.

  In S47, when the total number Px is not within the allowable range of the number (Px> (1 + α) · Po), the process proceeds to Step S49, the green LED 21 is flashed and the process ends.

  In step S46, it is determined whether or not the total number Px is equal to or greater than the target value Po of the number. If the total number Px is not equal to or greater than the target value Po, the process ends and the total is continued.

  When the total number Px is equal to or larger than the target value Po in S46, the process proceeds to step S48, and it is determined whether or not the total number Px is within the allowable range of the number (Po ≦ Px ≦ (1 + α) · Po). When the total number Px is within the allowable range, the process proceeds to step S50, the green LED 21 is turned on, and the process ends.

  In S48, when the total number Px is not within the allowable range of the number (Px> (1 + α) · Po), the process proceeds to step S49, the green LED 21 is flashed, and the process ends.

  With the above processing, when both the LEDs 23 and 21 of the total weight display yellow LED 23 and the total number display green LED 21 are turned on or flashing, both the total weight and the number are displayed. In any case, the target value is reached, and the worker replaces the storage container in which the article 14 is stored with a new storage container, assuming that the batch counting is completed.

  When the batch counting is completed, the operator counts the articles 14 stored in the storage container as shown in Table 2 when the yellow LED 23 for displaying the total weight is continuously lit not flashing. It is possible to grasp that the total weight Wtx is within an allowable range (Wto ≦ Wtx ≦ (1 + α) · Wto) equal to or greater than the target value Wto, and when the yellow LED 23 is flashing, the total weight Wtx is counted. It can be understood that the total weight Wtx exceeds the allowable range (Wtx> (1 + α) · Wto).

  Further, when the batch counting is completed, the operator can count the total number of articles 14 stored in the storage container, as shown in Table 2, when the total number display green LED 21 is continuously lit instead of flashing. It can be determined that Px is within an allowable range (Po ≦ Px ≦ (1 + α) · Po) that is equal to or greater than the target value Po, and when the green LED 21 is flashing, the total number Px is allowable. It can be understood that the range is exceeded (Px> (1 + α) · Po).

  In this way, the operator can grasp that the batch counting has been completed based on the lighting state of the yellow LED 23 for displaying the total weight and the green LED 21 for displaying the total number, and the storage containers that have been batch-counted. It is possible to grasp which quality rank of the article 14 is A, B, C, or D shown in Table 2. Thus, the worker can easily sort the storage containers in which the articles 14 are stored into the quality ranks A, B, C, and D, and can pack them for each quality rank.

<Third specification>
Next, a case where the third specification is selected will be described.

  FIG. 6 is a flowchart showing the process of the third specification, and Table 3 shows the status of the total number Px and the total weight Wtx corresponding to the process of FIG. It shows the lighting state of the LEDs 21, 23, 24.

この第３の仕様は、集計個数Ｐｘが、目標値Ｐｏに達すると、合計重量Ｗｔｘの如何に拘らず、バッチ集計を完了するものであり、表３に示すように、合計重量Ｗｔｘが、目標値Ｗｔｏを下回る品質ランクＣ，Ｄ，Ｇ，Ｈが存在する。

In the third specification, when the total number Px reaches the target value Po, batch totaling is completed regardless of the total weight Wtx. As shown in Table 3, the total weight Wtx is equal to the target weight Po. There are quality ranks C, D, G and H below the value Wto.

  In the third specification, as shown in FIG. 6, first, it is determined whether or not the total number Px is equal to or greater than the target value Po of the number (step S61), and when the total number Px is not equal to or greater than the target value Po, the process ends. And continue counting.

  When the total number Px is greater than or equal to the target value Po in S61, the process proceeds to step S62, and it is determined whether or not the total number Px = the target value Po. When the total number Px = target value Po, the process proceeds to step S63, the green LED 21 is turned on, and the process proceeds to step S65.

  If the total number Px is not the target value Po in S62, the total number Px> the target value Po, the process proceeds to step S64, the green LED 21 is flashed, and the process proceeds to step S65.

  In S65, it is determined whether or not the total weight Wtx is greater than or equal to the weight target value Wto. When the total weight Wtx is equal to or greater than the target value Wto, the process proceeds to step S66, and it is determined whether or not the total weight Wtx is within the allowable weight range (Wto ≦ Wtx ≦ (1 + α) · Wto).

  When the total weight Wtx is within the allowable range in S66, the process proceeds to step S68, the yellow LED 23 is turned on, and the process proceeds to step S72. When the total weight Wtx is not within the allowable range in S66 (Wtx> (1 + α) · Wto), the process proceeds to step S69, the yellow LED 23 is flashed and the process proceeds to step S72. In S72, the red LED 24 is turned off and the process ends.

  In S65, when the total weight Wtx is not equal to or greater than the target value Wto (Wtx <Wto), the process proceeds to step S67, and it is determined whether or not the total weight Wtx is within an allowable range ((1-α) · Wto ≦ Wtx <Wto). To do. In this case, it is determined whether or not the target value Wto is within an allowable range in the minus direction.

  When the total weight Wtx is within the allowable range in S67, the process proceeds to step S70, the red LED 24 is turned on, and the process proceeds to step S73. When the total weight Wtx is not within the allowable range in S67 (Wtx <(1-α) · Wto), the process proceeds to step S71, the red LED 24 is flashed and the process proceeds to step S73. In S73, the yellow LED 23 is turned off and the process ends.

  In the third specification, as described above, when the total number Px reaches the target value Po, the batch total is completed regardless of the total weight Wtx that has been totalized. The green LED 21 is lit or flashed. When the green LED 21 is continuously lit instead of flashing, as shown in Table 3, it can be determined that the total number Px matches the target value Po, and the green LED 21 When the flashing is on, it can be grasped that the total number Px exceeds the target value Po.

  Note that the case where the total number Px exceeds the target value Po is, for example, the case where the batch total is continued due to the delay in replacement of the storage container by the operator despite the completion of the batch total. Can be assumed.

  When the batch total is completed, if the total weight Wtx is within the allowable range equal to or greater than the target value Wto (Wto ≦ Wtx ≦ (1 + α) · Wto), as shown in Table 3, the total weight is displayed. When the yellow LED 23 is lit and exceeds the allowable range (Wtx> (1 + α) · Wto), the yellow LED 23 is flashed. In any case, as shown in Table 3, the red LED 24 for displaying the total weight is turned off.

  Further, when the batch totaling is completed, when the total weight Wtx is within an allowable range lower than the target value Wto ((1-α) · Wto ≦ Wtx <Wto), as shown in Table 3, When the total weight display red LED 24 is turned on and is below the allowable range (Wtx <(1-α) · Wto), the red LED 24 is flashed. In either case, the yellow LED 23 is turned off as shown in Table 3.

  Based on the lighting state of the green LED 21 for displaying the total number, and the lighting or extinguishing state of the yellow and red LEDs 23, 24 for displaying the total weight, the operator can determine that the batch 14 has been collected. It is possible to grasp which quality rank is A, B, C, D, E, F, G, or H shown in Table 3. As a result, the worker can easily sort the storage containers in which the articles 14 are stored into the quality ranks A, B, C, D, E, F, G, and H, and pack the containers for each quality rank. Is possible.

  In Table 3, priority is given to the coincidence of the target values Po of the total number Px, and the quality rank is evaluated in order from A to H in the proper order of the total weight Wtx, but the evaluation of the quality rank is limited to this. Yes. For example, the suitability of the total weight Wtx is evaluated low, the quality ranks A and B are the first quality rank, the quality ranks C and D are the second quality rank, the quality ranks E and F are the third quality rank, and the quality ranks G and H May be classified into four quality ranks as the fourth quality rank. Alternatively, focusing on the fact that the total weight Wtx is equal to or greater than the target weight Wto, the quality ranks A and B are the first quality rank, the quality ranks E and F are the second quality rank, and the quality ranks C and D are the third quality rank. The quality ranks G and H may be classified into four quality ranks as the fourth quality rank.

<Fourth specification>
Next, a case where the fourth specification is selected will be described.

  FIG. 7 is a flowchart showing the process of the fourth specification, and Table 4 shows the status of the total number Px and the total weight Wtx corresponding to the process of FIG. The lighting states of the LEDs 21, 22, and 23 are shown.

この第４の仕様は、合計重量Ｗｔｘが、目標値Ｗｔｏに達すると、集計個数Ｐｘの如何に拘らず、バッチ集計を完了するものであり、表４に示すように、集計個数Ｐｘが、目標値Ｐｏを下回る品質ランクＣ，Ｄ，Ｇ，Ｈが存在する。

In the fourth specification, when the total weight Wtx reaches the target value Wto, the batch counting is completed regardless of the total number Px. As shown in Table 4, the total number Px is equal to the target number Wto. There are quality ranks C, D, G, H below the value Po.

  In the fourth specification, as shown in FIG. 7, first, it is determined whether or not the total weight Wtx is equal to or greater than the target weight value Wto (step S81). If the total weight Wtx is not equal to or greater than the target value Wto, the process ends. And continue counting.

  If the total weight Wtx is greater than or equal to the target value Wto in S81, the process proceeds to step S82, and it is determined whether or not the total weight Wtx is within the allowable weight range (Wto ≦ Wtx ≦ (1 + α) · Wto). When the total weight Wtx is within the allowable range, the process proceeds to step S83, the yellow LED 23 is turned on, and the process proceeds to step S85.

  When the total weight Wtx is not within the allowable range in S82 (Wtx> (1 + α) · Wto), the process proceeds to step S84, the yellow LED 23 is flashed and the process proceeds to step S85.

  In S85, it is determined whether or not the total number Px is equal to or greater than the target value Po of the number. When the total number Px is equal to or greater than the target value Po, the process proceeds to step S86, and it is determined whether or not the total number Px is within the allowable number range (Po ≦ Px ≦ (1 + α) · Po). When the total number Px is within the allowable range, the process proceeds to step S88, the green LED 21 is turned on, and the process proceeds to step S92. When the total number Px is not within the allowable range in S86 (Px> (1 + α) · Po), the process proceeds to step S89, the green LED 21 is flashed and the process proceeds to step S92. In step S92, the blue LED 22 is turned off and the process ends.

  When the total number Px is not equal to or greater than the target value Po in S85 (Px <Po), the process proceeds to step S87, where it is determined whether the total number Px is within the allowable range of the number ((1-α) · Po ≦ Px <Po). To do. In this case, it is determined whether the target value Po is within the allowable range in the minus direction.

  When the total number Px is within the allowable range in S87, the process proceeds to step S90, the blue LED 22 is turned on, and the process proceeds to step S93. When the total number Px is not within the allowable range in S87 (Px <(1-α) · Po), the process proceeds to step S91, the blue LED 22 is flashed and the process proceeds to step S93. In step S93, the green LED 21 is turned off and the process ends.

  In the fourth specification, when the total weight Wtx reaches the target value Wto, the batch total is completed regardless of the total number Px. As shown in Table 4, the total weight is displayed. The yellow LED 23 for lighting is in a lighting state of either lighting or flashing lighting. When the yellow LED 23 is continuously lit instead of flashing, as shown in Table 4, the aggregated total weight Wtx is within an allowable range equal to or more than the target value Wto, and the yellow LED 23 is flashing lit. Sometimes, the total weight Wtx exceeds the allowable range.

  When the batch count is completed, if the total count Px is within the allowable range equal to or greater than the target value Po (Po ≦ Px ≦ (1 + α) · Po), as shown in Table 4, the total count display When the green LED 21 is turned on and exceeds the allowable range (Px> (1 + α) · Px), the green LED 21 is flashed. In either case, as shown in Table 4, the blue LED 22 for displaying the total number is turned off.

  Further, when batch counting is completed, when the total number Px is within an allowable range lower than the target value Po ((1-α) · Po ≦ Px <Po), the totaling is performed as shown in Table 4. When the blue LED 22 for displaying the number is turned on and is below the allowable range (Px <(1−α) · Po), the blue LED 22 is flashed. In any case, as shown in Table 4, the green LED 21 for displaying the total number is turned off.

  In the fourth specification, when the yellow LED 23 for displaying the total weight is in the lighting state of either lighting or flashing lighting, the worker assumes that the batch counting has been completed, and that the article 14 is contained. Replace the container with a new container.

  When this batch counting is completed, the operator performs batch counting based on the lighting state of the yellow LED 23 for displaying the total weight and the lighting or extinguishing state of the green and blue LEDs 21 and 22 for displaying the total number. It can be ascertained whether the quality of the article 14 in the container is A, B, C, D, E, F, G, or H shown in Table 4. As a result, the worker can easily sort the storage containers in which the articles 14 are stored into the quality ranks A, B, C, D, E, F, G, and H, and a box for each quality rank. It becomes possible to clog.

  In Table 4, priority is given to the total weight Wtx being equal to the target value Wto, and the quality rank is evaluated in order from the A to H in the proper order of the total number Px. It is not limited to. For example, the appropriateness of the total number Px is evaluated low, the quality ranks A and B are the first quality rank, the quality ranks C and D are the second quality rank, the quality ranks E and F are the third quality rank, and the quality ranks G and H May be classified into four quality ranks as the fourth quality rank. Alternatively, focusing on the fact that the total number Px is equal to or greater than the target value Po, the quality ranks A and B are the first quality rank, the quality ranks E and F are the second quality rank, and the quality ranks C and D are the third quality rank. The quality ranks G and H may be classified into four quality ranks as the fourth quality rank.

A lamp is provided, and each of the LEDs 21 to 24 directly displays the quality A, B, C, and D, and is applied only to the first specification described above.

  As shown in FIG. 8, first, it is determined whether or not the total number Px is smaller than the target value Po of the number (step S101). When the total number Px is smaller than the target value Po, the process ends and the totaling is continued.

  When the total number Px is not smaller than the target value Po in S101, the process proceeds to step S102, and it is determined whether or not the total number Px = the target value Po. When the total number Px = target value Po, the process proceeds to step S103, the number flag is set to “1”, and the process proceeds to step S105. When the total number Px = target value Po is not satisfied at S102, the number flag is set to “0”. Reset and go to step S105.

  In step S105, it is determined whether or not the total weight Wtx is equal to or greater than the weight target value Wto. When the total weight Wtx is not equal to or greater than the target value Wto, the process ends and the counting is continued.

  When the total weight Wtx is equal to or larger than the target value Wto in S105, the process proceeds to step 106, and it is determined whether or not the total weight Wtx is within the allowable weight range (Wto ≦ Wtx ≦ (1 + α) · Wto).

  When the total weight Wtx is within the allowable range in S106, the process proceeds to Step S107, and it is determined whether or not the number flag is “1”. In S107, when the number flag is “1”, the green LED 21 corresponding to the quality rank A is turned on and the process ends (step S109). When the number flag is not “1”, the yellow corresponding to the quality rank C is displayed. The LED 23 is turned on and the process ends (step S110).

When the total number Px = target value Po, the process proceeds to step S203, the number flag is set to “1”, and the process proceeds to step S205.

  If the total number Px is not the target value Po in S202, the total number Px> the target value Po, the process proceeds to step S204, the number flag is reset to “1”, and the process proceeds to step S205.

  In S205, it is determined whether or not the total weight Wtx is greater than or equal to the weight target value Wto. When the total weight Wtx is equal to or greater than the target value Wto, the process proceeds to step S206, and it is determined whether or not the total weight Wtx is within the allowable weight range (Wto ≦ Wtx ≦ (1 + α) · Wto).

  When the total weight Wtx is within the allowable range in S206, the process proceeds to step S209, where it is determined whether or not the number flag is “1”, and when the number flag is “1”, the LED 21 of quality rank A is turned on. When the number flag is not “1”, the LED 25 of the quality rank E is turned on and the process ends (step S215).

  When the total weight Wtx is not within the allowable range in S206, the process proceeds to step S208, where it is determined whether or not the number flag is “1”. When the number flag is “1”, the LED 22 of quality rank B is turned on. When the number flag is not “1”, the LED 26 of the quality rank F is turned on and the process ends (step S213).

  In S205, when the total weight Wtx is not equal to or greater than the target value Wto (Wtx <Wto), the process proceeds to step S207, and it is determined whether or not the total weight Wtx is within an allowable range ((1-α) · Wto ≦ Wtx <Wto). To do. In this case, it is determined whether or not the target value Wto is within an allowable range in the minus direction.

When the number flag is not “1”, the LED 27 of the quality rank G is turned on and the process ends (step S216).

  If the total weight Wtx is not within the allowable range in S207 (Wtx <(1-α) · Wto), the process proceeds to step S211 to determine whether the number flag is “1” and the number flag is “1”. If it is, the LED 24 of the quality rank D is turned on and the process ends (step S219). If the number flag is not “1”, the LED 28 of the quality rank H is turned on and the process is ended (step S218).

  In addition to the notification by lighting the lamp, the quality may be displayed by characters on the liquid crystal display device, the notification may be made by voice, or the display and the voice may be combined. In the case of the notification by characters or the notification by voice by the liquid crystal display device, it is not necessary to provide for each storage container, for example, it may be installed at one place.
