Abstract

PURPOSE:To improve the probability of obtaining an excellent combination causing little increase, by changing appropriately the range of weight for each combination balance line for distributing articles to each of the lines in a plurality in accordance with a calculated rate of difficulty. CONSTITUTION:Each combined balance provided for each of combination balance lines 14 and 15 for large chicks and small chicks inputs a weighed value to an average value calculating means 17, a fraction rate calculating means 18 and a scattering rate calculating means 19 every time when a prescribed number of chicken pieces are weighed. A numerical value obtained by each of the calculating means 17 to 19 is outputted to a difficulty rate calculating means 11 and a rate of difficulty is calculated. The rate of difficulty is a numerical value showing the possibility that no combination within a predetermined range of an allowable amount exists in combinations of weighed values of a plurality of articles when combined weighing is executed. Based on the rate of difficulty calculated at each prescribed period, a weight range selecting means 10 selects a weight range for mixing and a weight range for removal and updates data set in a weight selector 13. According to this constitution, the combined balance on each of the lines 14 and 15 can select and determine an allowable range of weight in high probability.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for distributing articles to a combination weighing line that distributes articles such as breast meat and leg meat of a broiler to a plurality of combination weighing lines.

[0002]

2. Description of the Related Art The measurement and shipping system for the above-mentioned broiler meat breast meat and thigh meat (hereinafter, the breast meat and thigh meat are collectively referred to as the regular meat) is shipped by separately packing each breast meat and thigh meat as 2 kg. is doing. The weight of the regular meat (piece weight) is 180-250g for the breast meat and 200-for the leg meat.
Since it is about 330g, 7 to 11 pieces of meat per package
It is about one piece. Before the combination weigher was adopted in the weighing and shipping system, it was difficult to weigh 2 kg because it was manually weighed using a platform scale such that one packaging unit weighs 2 kg. It takes a lot of manpower and time, and the increase is 2kg (a little more than the weight of one packaging unit is less than 2kg).
However, there is a problem in that the yield is poor.

Therefore, a combination scale is adopted, and the average increase is 0.1 to 0.2% with respect to 2 kg by automatic quantitative measurement.
However, compared to the case of manual work, the number has decreased remarkably. However, as a recent trend, automatic dismantling machines have been adopted for some of the dismantling work of broilers due to automation of weighing.

Since this automatic dismantling machine has a limited range of broiler sizes, it is difficult to disassemble all sizes of the broiler. Therefore, the broiler must be preliminarily subjected to a weight sorter (the weight and shape of the broiler are large). ) And small broilers (the weight and shape of the broiler are small), and the large wing is dismantled by the automatic dismantling machine for large wing, and the small wing is dismantled by the automatic dismantling machine for small wing. That is, a conventional weighing and shipping system that employs an automatic dismantling machine calculates the average weight of broilers by weighing a predetermined number of broilers transported by a truck on a truck, as shown in FIG. A boundary weight value for selecting a broiler into large and small ones is calculated (step 100). Then, disassembly pretreatment is performed (step 102). Next, the objects are weighed one by one by a multi-stage weight sorter, and sorted into large, small, and other external products based on the boundary weight value (step 10).
4). Then, the large obana is supplied to an automatic dismantling machine for the large and is subjected to the large disintegration process (step 106), and then the small disintegration process is manually performed to prepare large-sized thigh meat and breast meat, chicken wings, by-products ( (Built-in, etc.) (step 108). These thigh meat, breast meat, etc. are automatically weighed separately by a combination weigher to a predetermined weight (for example, 2 kg), collected into one packaging unit, and conveyed to the subsequent packaging and shipping line (steps 110, 112, 114, 11
6), wrapped (step 118). Similarly, the small dislocation processing by the automatic dismantling machine for small dislocations (step 120) and the small disassembly processing by hand (step 12).
2) Then, combination weighing is performed by the combination weighing machine (steps 124, 126, 114, 116), and is conveyed to the packaging and shipping line and packaged (step 118). However, an extremely small size is processed in the non-standard product line (step 128).

[0005]

However, the combination scale is
The larger the standard deviation of the weight of the pieces of meat, the higher the probability of obtaining a good combination with little increase in weight. That is, when the large and small pieces are sorted and combined and weighed separately by the combination weigher (when the standard deviation is small), when the large and small pieces are mixed and weighed by the combined weigher As compared with (when the standard deviation is large), there is a problem that the probability of obtaining a good combination with a small increase in the number becomes lower.

In some cases, the combination within the allowable weight range is not obtained, and the re-combination weighing is performed (the re-combination weighing is an empty weighing when the combination within the allowable weight range is not obtained. When the articles are put into the hopper and the combination weighing is performed again.) When the re-weighing is performed, the processing capacity of the combination weighing (the number / time of selecting the combination within the allowable weight range) is reduced. Occurs.

[0007] Furthermore, at first, the size of the meat pieces was divided into large and small in order to match the ability of the automatic demolition machine, but the size division of large and small is required to improve the quality of products. However, there is a problem that it is not possible to indiscriminately mix large and small dwarfs and perform combined weighing. It is an object of the present invention to provide an article distribution device for a combination weighing line that solves the above problems.

[0008]

SUMMARY OF THE INVENTION The first to eighth inventions are, as shown in FIG. 1, a weight range (weight range) for each line for a weight sorter 1 to sort articles into a plurality of combination weighing lines 2, 3, and 4. The range selecting means 5) can be appropriately changed according to the difficulty level calculated by the difficulty level calculating means 6. The difficulty level is a numerical value indicating the possibility of the absence of a combination within a predetermined permissible weight range among combinations of measured values of a plurality of articles when combination weighing is performed by a combination scale. That is, the higher the difficulty level, the lower the probability of combinations within the allowable weight range. In other words, when the difficulty level is high, the width of the weight range for each line is widened according to the difficulty level to increase the variation in the weight of the articles within the weight range, which allows the combination weighing by the combination scale. In the above, the possibility of selecting a set of articles within the allowable weight range is increased. Furthermore, since the degree of increasing the variation in the weight range is determined according to the degree of difficulty, the variation in weight of the articles distributed to each combination weighing line does not indiscriminately increase, that is, The possibility that a set of articles within the allowable weight range is selected is increased to a predetermined rate, taking into consideration that the variation does not exceed a predetermined size. However,
The difficulty rate can be calculated by simulating with a combination scale based on the measurement data of pre-weighed goods or based on the measurement data obtained by measuring with the combination scale, and can also be obtained by the calculation formula described later. You can

According to a second aspect of the invention, a plurality of weight ranges are automatically set in the weight sorter based on, for example, the weight of articles obtained by weighing in advance. Then, when the degree of difficulty of the article is large, the plurality of weight ranges are assigned to each line and set in the weight sorter so that the variation in the weight of the article distributed to each combination weighing line becomes large. The weight sorter is characterized in that the weighed articles are sorted based on the weight range assigned to each line.

According to a third aspect of the invention, the weight classification is made to correspond to each weight rank (rank corresponding to the weight range of the articles distributed to each combination line) based on the weight of the articles obtained by weighing in advance. Set automatically. Then, when the difficulty level is high, the weight range is changed so that the weight variation of the articles distributed to each combination line becomes large according to the degree of the difficulty level. That is, one weight section is associated with one weight rank,
A predetermined weight range in the weight category is determined as a removal weight range to be removed from the weight rank, and a predetermined weight range included in another weight category other than the weight category is mixed as the mixing weight range. I have decided. However, each weight range of the removal weight range and the mixed weight range is determined for each value of the difficulty level, and the wider the weight range is, the larger the difficulty level is. It is set so that the weight variation of the articles distributed to the ranks becomes large. However,
The difficulty level is calculated based on the average value calculated by the average value calculating means, the fraction rate calculated by the fraction rate calculating means, and the variation rate calculated by the variation rate calculating means, which will be described in detail in the embodiments.

A fourth invention is such that an operator can manually set a plurality of weight ranges in the second invention on the weight sorter. A fifth aspect of the invention is such that an operator can manually set a weight range assigned to each line in the second aspect of the weight sorter. That is, with reference to the difficulty level output by the selected weight output means, and the set of weight ranges corresponding to this difficulty rate, the operator corrects the set of this weight range,
The corrected data can be set in the weight sorter. A sixth invention is such that an operator can manually set a plurality of weight sections in the third invention on the weight sorter.

In the seventh invention, the operator can manually set the mixing weight range included in each weight rank and the removal weight range to be removed from each weight rank in the weight sorter in the third invention. It was done. That is, the operator corrects and corrects the mixed weight range and the removed weight range with reference to the difficulty rate output by the selected weight output means and the mixed weight range and the removed weight range corresponding to the difficulty rate. The data can be set in the weight sorter. An eighth invention is the first to seventh inventions.
In the invention described above, when the difficulty level is equal to or higher than a predetermined value, an alarm is output.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to the drawings. In this embodiment, the difficulty rate calculating means calculates the weight range of each line for distributing the carcasses of the broiler to the large line, the small line and the non-external product line in the weight sorter shown in FIG. It can be appropriately changed according to the difficulty level. In other words, if the number of broilers and the carcass weight value are in the relationship shown in FIG. 3, the carcass having the weight in the A zone should be used as the extra product line and the carcasses having the weights in the B and D zones should be small. The carcasses having the weights of the C zone and the E zone are distributed to the large work lines. However,
Depending on the magnitude of the difficulty level, the width of the weight range of the C zone and the D zone is set wider as the difficulty level increases.

FIG. 2 is an electrical block diagram of the apparatus used in this embodiment. In FIG. 2, 7 is a track scale, which outputs the measured value to the weight classification determining means 8 (calculation starting unit). The weight classification determining means 8 determines the boundary weight value based on the measured value and the data input by the keyboard 9, and outputs it to the weight range selecting means 10. The weight range selection means 10 selects, based on the difficulty rate calculated by the difficulty rate calculation means 11, a predetermined mixed weight range and a removal weight range corresponding to the difficulty rate from the data stored in the storage means 12, The selected data and the boundary weight value are output to the weight sorter 13 to set the weight ranges corresponding to the large scale combination weigher line 14, the small scale combination weigher line 15 and the external product line 16. . The weight sorter 13 sorts the weighed articles (carcasses of broilers) into respective weight ranks for each combination weighing line corresponding to the carcass weight and each extraneous product line. And each combination scale provided in the combination scale line for large and small scales, each time the weight of a predetermined number of meat pieces is weighed,
The respective measured values are output to the average value calculation means 17, the fraction rate calculation means 18, and the variation rate calculation means 19. Then, each of these calculation means outputs the calculated numerical value to the difficulty rate calculation means 11. The difficulty level calculation means 11 calculates the difficulty level based on these numerical values. That is, the weight range selection means 10
The mixed weight range and the removed weight range are selected based on the difficulty rate calculated by the difficulty rate calculation means 11 for each certain period, and the selected data is changed to the data set in the weight sorter 13 last time. This allows the combination weigher to select a combination in the allowable weight range with a sufficiently high probability, and the carcasses to be distributed to the small line 15 as much as possible are not distributed to the large line 14 as much as possible. In this way, the carcasses to be distributed to the large line 14 are prevented from being distributed to the small line 15 as much as possible. However, the combination weighing line for small items, the combination weighing line for small items, and the external product line are the same as those described with reference to FIG. 11 of the conventional example, and thus detailed description thereof will be omitted.

These processing functions will be described in detail below. The truck scale 7 weighs the broilers that have been fed by a truck from a poultry farm by a predetermined number of birds and carried by the truck, and weighs the broiler, and outputs the weighed value to the weight classification determining means 8.

The keyboard 9 is used for inputting the weight of empty trucks, the weight of baskets, the number of baskets placed on the trucks, and the number of broilers in one basket to the weight classification determining means 8. Is.

The weight classification determining means 8 determines the boundary weight value for sorting the received broiler into large and small by the weight sorter 13. For example, the average weight value of the received broilers is calculated based on the total weight value from the truck scale 7 and the data from the keyboard 9, and this average weight value is used as the boundary weight value. That is, the boundary weight value shown in FIG. 3 is determined. Then, basically, a broiler having a weight heavier than the boundary weight value is distributed to a large use line, and a broiler having a light weight is distributed to a small use line through the weight range selecting means 10 so that the weight sorter is selected. It is set to 13. The keyboard 9 and the weight classification determining means 8 are provided in the device of the track scale 7.

The difficulty rate calculation means 11 is an average value calculation means 1.
7. Based on the numerical values calculated by the respective calculation means of the fraction rate calculation means 18 and the variation rate calculation means 19, there is no combination within the predetermined allowable weight range among the combinations of the weights of the pieces of meat measured by the combination scale. The difficulty rate representing the possibility of is calculated.
Each combination weigher provided on the large and small lines measures the weight of the supplied meat pieces, combines the measured values of these meat pieces in various ways, and calculates the total weight from each of these combinations. Has a combination calculation means for selecting a combination within a predetermined allowable weight range.

The average value calculating means 17 calculates an average value (average number of selected pieces) of the number of meat pieces selected each time when the combination is selected a predetermined number of times by the combination calculating means. Usually, when the weight per pack is 2 kg and the number of meat pieces selected for the combination is 6 to 7, the number of combinations that fits exactly within the allowable weight range is small, and therefore the allowable weight range is It can be said that there is a high possibility that the combination within does not exist. And, when the number of meat pieces selected for the combination is about 11 to 12 pieces, there are a large number of combinations which are just within the allowable weight range, and therefore,
It can be said that there is a low possibility that there will be no combination within the allowable weight range. In consideration of the above, (11-average number of selections) = variable coefficient is used as a parameter for calculating the difficulty level, and is set to 0 when the average value is larger than 11.

The fraction rate calculation means 18 is the average value calculation means 1
The fraction below the decimal point generated in the average selected number calculated by 7 is divided by this average selected number to calculate the fraction rate. In addition,
If the fraction exceeds 0.5, 1 is added to the original average selection number.
Is added and the original fraction is a, 1-a is the fraction of the average selection number obtained by adding 1. That is, the fraction is 0.
The closer to 5, the greater the fractional ratio, and the greater the fractional ratio, the smaller the number of combinations. That is, for example, if the average number of selections is 13.5,
It indicates that there is a combination between the selected discharge numbers 13 and 14 that exactly fits within the allowable weight range. Therefore, in this case, it can be said that the smaller the number of suitable combinations, and thus the larger the fractional ratio, the higher the possibility of the absence of combinations within the allowable weight range. However, even if the fractional ratio is 0, the average selected number that is the basis of the calculation of the fractional ratio is only an average value. Therefore, in the actual individual combination weighing, there is no combination within the allowable weight range. It cannot be said that there is no possibility at all, that is, there is not always a combination within the allowable weight range, so (fractional rate +1) is set as a parameter for calculating the difficulty level.

The variation rate calculation means 19 calculates the standard deviation of the weight of a predetermined number of pieces of meat weighed by the combination weigher,
The standard deviation is divided by the average value of the weight of the predetermined number of pieces of meat to calculate the variation rate. That is, variation rate = (standard deviation σ of meat piece / average weight value of meat piece)
・ It is defined as 100 [%]. The variation rate is about 14% when the broilers are not classified into large and small. In this case, a good combination (there are many combinations within the allowable weight range) is selected regardless of the fractional ratio and the variable coefficient. Therefore, (14−variation rate) is set as a parameter for calculating the difficulty rate, and is set to 0 when the variation rate is larger than 14. That is, the difficulty rate calculation means 11 calculates the difficulty rate = (fractional rate + 1) * (14-variation rate) * (1
1-average selection number) to calculate the difficulty level.

The storage means 12 stores the correspondence shown in FIG. That is, the weight width of the C zone and the weight width of the D zone shown in FIG. 3 are set to be equal. And the difficulty rate α
<In the case of threshold value a, the weight width is set to 50 g, and in the case of threshold value a ≦ difficulty rate α ≦ threshold value b, the weight width is set to 100 g
When threshold value b <difficulty rate α, the weight width is 150
The data of g is stored. Although the broilers in the B and D zones are distributed to the weight rank of the small pet line, this D zone is referred to as a mixed weight range with respect to the weight rank of the small pet line. And, the weight range removed from the weight rank of the small pet line is the C zone,
This C zone is referred to as a removal weight range with respect to the weight rank of the small service line. Further, the broilers in the C and E zones are distributed to the weight rank of the extensive service line, and this C zone is called a mixed weight range with respect to the weight rank of the extensive service line. The weight range removed from the weight rank of the extensive service line is the D zone, and this D zone is referred to as the removed weight range with respect to the weight rank of the extensive service line. However, the weight widths of the C and D zones are the lower limit values for the automatic dismantling machine for large objects shown in Fig. 3 (the lower limit weight value that can be dismantled by the large dismantling machine for small objects) and the upper limit value for automatic dismantling machines for small objects (dismantling small objects for small objects). The upper limit weight value that can be dismantled by the machine) is set so that it does not mix articles with a weight range less than the lower limit value for automatic dismantling machines into the large dismantling line and for small machines. This is for preventing articles having a weight range of the automatic dismantling machine upper limit or more from being mixed with the small line.
In addition, the fraction rate calculation means 18, the variation rate calculation means 19,
Average value calculation means 17, difficulty level calculation means 11, storage means 1
2 is provided in the control device of the combination weigher.

The weight range selecting means 10 stores the weight width corresponding to the difficulty rate calculated by the difficulty rate calculating means 11 in the storing means 12.
Is selected from the data (shown in FIG. 7) stored in, and the selected weight width is set in the weight sorter 13. The weight range selecting means 10 is provided in the weight sorter 13.

The weight sorter 13 weighs the broilers that have undergone disassembly pretreatment one by one, and the weight of the carcass obtained by weighing the broilers is set by the weight range selecting means 10.
Determine which zone it belongs to. Then, it is determined which weight rank of the large service line, the small service line, or the external product line to which the zone obtained by this determination belongs, and the weighed broilers are distributed to the determined line.

The large scale combination weighing line (large scale line), the small scale combination scale line (small scale line) and the external product line are steps 106 to 128 shown in FIG.
This corresponds to (excluding step 118). However, each of the combination scales provided on the large line and the small line measures the measured value of each piece of meat every time a predetermined number of pieces of meat are weighed, the average value calculation means 17, the fraction ratio calculation means 18, and the variation. The output to the rate calculation means 19 is different from the conventional one.

Next, the operation of the article distributing device for the combination weighing line of this embodiment will be described with reference to the respective flowcharts. First, the procedure for transmitting the boundary weight value from the track scale 7 side to the multi-stage weight sorter 13 will be described with reference to the flowchart shown in FIG. First, enter the truck that loads the broiler in the basket (step 200),
The total weight of the truck is measured by the truck scale 7 (step 202). At this time, the empty truck weight, one basket weight, the number of baskets, and the number of broilers in one basket are input to the weight classification determining means 8 by operating the keyboard 9 (step 2).
04), the weight classification determining means 8 calculates the average weight of the broiler, that is, FIG.
Is calculated (step 206), and this boundary weight value is transmitted to the multi-stage weight sorter 13 (step 21).
0). The boundary weight value is displayed on a display unit (not shown) such as a cathode ray tube and printed by a printer (step 208).

A procedure for the combination scale to transmit the mixing width (mixing weight range, removal weight range) corresponding to the difficulty rate to the multi-stage weight sorter 13 will be described with reference to the flowchart shown in FIG. First, the broiler meat pieces and the like that have been subjected to the small disintegration process are weighed (step 300), and based on the measured values, the fraction ratio calculation means 18, the variation ratio calculation means 19, and the average value calculation means 17 (fraction ratio + 1), (14-variation rate),
(11-average number of selections) is calculated (step 302,
304, 306). Then, the difficulty rate calculation means 11 causes the difficulty rate = (fractional rate + 1) * (14-variation rate) * (11-
The average selected number) is calculated (step 308). However, the difficulty level should be calculated for each combination scale of the big and small lines, and the larger of the two calculated difficulty levels shall be adopted as the final difficulty rate. The average value of the two difficulty levels may be adopted as the final difficulty rate. Next, the weight range selecting means 10 selects the corresponding mixing width from the figure showing the correspondence relationship stored in the storage means 12 based on the calculated difficulty level (step 310), and makes this selection. The mixed width is transmitted to the multi-stage weight sorter 13 (step 312).

The flow chart of FIG. 6 shows a procedure in which the multi-stage weight sorter 13 weighs meat pieces and distributes the measured meat pieces to a predetermined line. First, the operator sets the upper limit value of the zone A shown in FIG. 3, which corresponds to the weight rank of the external product line, that is, the external product weight value, to the weight sorter 13 (step 400). Then, when the boundary weight value is input from the track scale 7 side (weight classification determining means 8) (step 402) and the mixing width is input from the combination scale (step 404), the weight regions of zones A to E shown in FIG. 3 are input. It is determined (step 406). Then, when the broilers subjected to the disassembly pretreatment are sequentially supplied to the weight sorter 13, the carcass weight is measured (step 408) and the carcass weight belongs to any of the zones A to E. It is determined (steps 410 to 416). Then, the broilers whose carcass weight belongs to the A zone are distributed to the extra-product line (step 418), and the broilers belonging to the B zone and the D zone are distributed to the small line (step 42).
0), and the broilers belonging to the C zone and the E zone are allotted to extensive lines (step 422). In addition,
When the weight sorter 13 weighs the carcass and distributes the broilers to a predetermined line, the difficulty rate calculation means 11
A new difficulty rate is transmitted from the weight range selecting means 10 to the weight range selecting means 10, and a new weight range is set in the weight sorter 13 based on this new difficulty rate. Based on this, the broilers are assigned to the corresponding lines. In other words, when the unit weight of the meat pieces measured by the combination scale fluctuates and, for example, the difficulty rate increases due to this fluctuation, a mixing width corresponding to the magnitude of the difficulty rate is newly selected, and the selected mixing width is selected. The width is set on the weight sorter 13. As a result, even if the unit weight of the meat pieces supplied to the combination scale fluctuates, the ratio of the number of times of recombination measurement by the combination scale (the number of times of recombination measurement / the number of times of combination measurement) is set to a predetermined level corresponding to the difficulty rate. The ratio can be set to be not more than the ratio, and the variation in weight of the meat pieces packaged in the pack can be kept within a predetermined weight range corresponding to the difficulty rate.

A second embodiment will be described with reference to the electrical block diagram shown in FIG. In the second embodiment, a weight range determining means (not shown) is provided instead of the weight classification determining means 8, and the weight range selecting means 10 and the storage means 12 are the first.
It differs from that of the embodiment. However, other parts are first
The description is omitted because it is the same as the embodiment.

The weight range determining means is the track scale 7.
The boundary weight value (average weight) of the broiler is calculated on the basis of the input weight value and the data input from the keyboard 9, and the boundary weight value is used as a reference for the minus side and the plus side as shown in FIG. Six C-H zones with a weight width of, for example, 50 g are determined. Then, the weight ranges of the six C to H zones and the B and I zones are selected as the weight range selecting means 10.
Call. The threshold value for determining the A zone (the weight value of the non-isolated product) is set in the weight sorter 13 by the operator as in the first embodiment.

The storage means 12 stores the correspondence shown in FIG. That is, when the difficulty rate α <the threshold value a,
The B, C, D, and F zones are associated with the small work lines, and the I, E, G, and H zones are stored with the large work lines. In the case of threshold value a ≦ difficulty rate α ≦ threshold value b, the small work line is associated with the B, C, F, and G zones, and the large work line is associated with the I, D, E, and H zones. I remember. If the threshold value b <difficulty rate α, the B, F, G, and H zones are associated with the minor line, and the I, C, D, and E zones are associated with the major line, and stored. . However, the C to H zones of the mixing weight range are set between the large automatic dismantling machine lower limit value and the small automatic dismantling machine upper limit value shown in FIG. 9 as in the first embodiment.

The weight range selection means 10 stores the set of zones corresponding to the difficulty rate calculated by the difficulty rate calculation means 11 in the storage means 12 for each weight rank of each line (data shown in FIG. 10). ), A weight sorter 1
Set to 3. Therefore, each time the weight sorter 13 sequentially measures the carcass weight of the broiler, it can determine the zone to which the weight belongs and distribute the weighed broiler to the corresponding line. Then, if the difficulty level is updated corresponding to the change in the measured value, the combination of zones corresponding to the difficulty level is set for each weight rank of the small usage line and the large usage line as in the first embodiment. , Is selected from the data of the storage means 12 and set in the weight sorter 13.

However, in the first embodiment, as shown in FIG. 7, the difficulty rate is divided into three stages, and the mixing width of three stages is determined and stored in the storage means 12 corresponding to each stage. As shown in, the difficulty level may be divided into five levels, and the mixing width of five levels may be determined corresponding to each level and stored in the storage unit 12. It should be noted that with reference to FIG.
It is divided into 5 stages by d, and a predetermined mixing width is stored in association with the difficulty level of each stage. The allowable width of the dismantling machine shown in the figure is a weight width between the lower limit value (upper limit value) and the boundary weight value of the large dismantling (small dismantling) dismantling machine shown in FIG. When the difficulty rate α is less than or equal to the threshold value b, no alarm is output to the memory portion called the manual mixing instruction warning, and the difficulty rate α
The information that the alarm is output when the value exceeds the threshold value b is stored. When the difficulty level α exceeds the threshold value a, the difficulty level is high in the memorized portion of the manual mixing rate, so that 20% of the broilers distributed to the small-sized line (or large-sized line) are stored. Information is stored that a numerical value of 20% is displayed on the display unit so as to manually adjust the number of pieces of meat to be mixed with a weight (or weight) of the pieces that are heavier (or lighter) than the boundary weight value. And
When threshold value b ≦ difficulty rate α ≦ threshold value a, information is stored that the numerical value of 10% is displayed on the display unit so that 10% of the meat pieces are mixed in the same manner as described above. Further, when the difficulty rate α is equal to or less than the threshold value b, the difficulty rate is small at this time, so that it is not necessary to manually adjust the mixing number, and information indicating that 0 is displayed on the display unit is stored. There is.

Of course, in the second embodiment, as shown in FIG. 10, the difficulty rate is divided into three stages, and the mixing zone of three stages is determined corresponding to each stage and stored in the storage means 12. Similar to the one shown in, the difficulty rate is divided into 5 levels, and 5 levels of mixing zones corresponding to each level, manual mixing warnings and manual mixing rates are set for each small and large line. It may be decided and stored in the storage means 12.

In the first and second embodiments, in the distribution device for distributing the articles to the large line and the small line, the articles having the weight within the predetermined weight range are mixed with each other according to the degree of difficulty. However, in addition to this, for example, in a distribution device that distributes articles to a large line, a medium line, and a small line, depending on the degree of difficulty, an item with a weight in a predetermined weight range is It is possible to mix the work line and the medium work line with each other, and to mix articles having a weight in a predetermined weight range other than the predetermined weight range with the middle work line and the small work line.

In the first embodiment, the weight classification determining means 8
Instead of calculating the average weight of the broiler, that is, the boundary weight value, the two weight categories divided by the boundary weight value are determined in correspondence with the weight ranks of large and small, for example, on the display unit. A weight classification output means for displaying is provided on the side of the track scale 7, and a weight classification setting means for allowing an operator to set the outputted weight classification for each weight rank of big and small in the weight sorter 13.

EFFECTS OF THE INVENTION According to the present invention, the weight variation of each article distributed to each combination weighing line is increased or decreased according to the degree of the difficulty rate calculated by the difficulty rate calculation means. If the difficulty level is high, it is possible to reduce the difficulty level by increasing the variation in the weight of each article distributed to each combination weighing line, and it is possible to select a combination within the allowable weight range. Can be higher. Therefore, the number of times of re-combination weighing can be reduced, so that there is an effect that it is possible to prevent a decrease in the processing capacity of the combination weighing. Moreover, since it is possible to achieve the purpose of minimizing the variation of the weight of the articles selected for the combination without excessively increasing the variation, the size of the meat piece can be set to be large or small as shown in the examples. By sizing, there is an effect that the combination weigher can be operated at a predetermined processing speed while maintaining the quality added to the product to some extent.

On the other hand, when the difficulty level is small, the articles are selected from a narrow weight range while maintaining the advantage that the articles of the combination within the allowable weight range can be selected with a high probability. There is an effect that the variation in the weight of the selected articles can be maintained in a narrow state. That is, when the difficulty level is low, while maintaining the quality of the size-separated products more than when the difficulty level is high,
There is an effect that the combination scale can be operated at a predetermined processing speed.
