Abstract

PROBLEM TO BE SOLVED: To improve weighing accuracy and weighing fastness of an adhesive or sticky article by selecting the weight value to be within a specified weight range by the combination of each weight value corresponding to each cup included in the first number to the specified number. SOLUTION: The number A of cups corresponding to the weight value partaking in combination is made ten, for instance, and when the selected number of the selected cups are four, that is, the fourth, sixth, eighth and tenth, the distance up to the arrival of the tenth cup at a stand-by position 42 becomes L4. But in the case of the selected number B being three and the cup to be stored with an article of the selected weight value being the tenth cup, the distance up to the arrival of the cup at the stand-by position 42 becomes L3, and L3 is longer than L4, so that conveyance time becomes longer compared with the case of the selected number being four. Accordingly, in the case of the selected number B being three which is less than four, the tenth cup is not used for combination. Even in the case of the selected number being two or one, the increase of conveyance time is thereby prevented to improve processing fastness.

2. Description of the Related Art A conventional combination weigher is provided with a conical dispersion table 1 as shown in a partially omitted sectional view of FIG. 11, and when the articles 2 to be weighed are supplied onto the dispersion table 1. The articles 2 can be moved and dispersed to the outer peripheral side by the centrifugal force of the dispersion table 1 or the like. Then, the articles 2 sent out from the outer peripheral edge of the dispersion table 1 are supplied to a plurality of straight advance feeders 3 provided along the outer peripheral edge of the dispersion table 1, and are gradually moved outward by the straight advance feeders 3. Be transported. These straight feeders 3
The articles 2 discharged from the leading end of the feeding hopper 4 are fed into the feeding hopper 4 provided below the leading end of the straight feeder 3, and the articles fed into the feeding hopper 4 are placed below the feeding hoppers 4. It is supplied to the existing weighing hopper 5. The articles 2 supplied to the weighing hopper 5 are
The weight 2 is weighed by the weight detector 6 that supports, and the weighed article 2 is supplied to the memory hopper 8 provided below the gate 7 inside the weighing hopper 5. When the weighing hopper 5 becomes empty, articles are supplied to the weighing hopper 5 and the weight of the articles is weighed in the same manner as described above. The respective weighing values of the weighed articles stored in the respective weighing hoppers 5 and the respective weighing values of the weighed articles stored in the respective memory hoppers 8 are combined and calculated and are equal to or closest to a predetermined weight. Is selected, and the article corresponding to the selected weighing value is discharged from the weighing hopper 5 and the memory hopper 8. Then, the discharged articles 2 are supplied to the collecting hopper 11 through the dividing chute 9 and the collecting chute 10, and are supplied from the collecting hopper 11 to the packaging machine 12.

[0003]

In the conventional combination weigher shown in FIG. 11, at least 10 to 14 weighing hoppers 5 are generally required, depending on the weighing accuracy. As a result, for example, these 10 to 14 weighing hoppers 5 are
When arranged on the circumference along the tips of the ~ 14 linear feeders 3, the diameter D of the circle (see FIG. 11) becomes a relatively large dimension. Further, in order to supply the selected articles for the combination to the packaging machine 12, the selected articles are packed in the packaging machine 1.
Since it is necessary to collect at one place on the two, it is supplied to one collecting hopper 11. Therefore, in the conventional combination weigher, as shown in FIG. 11, since the diameter D is relatively long, the length R of the path 13 from the weighing hopper 5 to the collecting hopper 11 is also relatively long.

However, when the length R of the path 13 is relatively long, the articles adhere to the inner wall surfaces of the dividing chutes 9 and the collecting chutes 10 forming the path 13 when the articles are adhesive or sticky. However, there is a problem in that the accuracy of combined weighing is reduced.

In the combination weigher shown in FIG. 11, since the memory hopper 8 is provided, the number of weighed articles that can participate in the combination can be increased, thereby improving the weighing accuracy of the combination weighing. I am allowed to do it. However, since it is necessary to supply the weighed articles 2 in the weighing hopper 5 to the memory hopper 8, when the articles have adhesiveness or adhesiveness, the amount of the articles attached to the weighing hopper 5 or the memory hopper 8 is small. There is a problem that the measurement accuracy increases in combination measurement due to the increase in the number. Therefore, in the case of an article having adhesiveness, the memory hopper 8 may not be provided in order to maintain a predetermined weighing accuracy.

Therefore, in order to maintain a predetermined weighing accuracy without providing the memory hopper 8, it is conceivable to increase the number of the weighing hoppers 5. However, when the number of the weighing hoppers 5 is increased, it is shown in FIG. Path 1 with increased diameter D
Since the problem that the length R of 3 becomes long occurs, there is a certain limit in increasing the number of the weighing hoppers 5. Further, if the number of the weighing hoppers 5 is increased, the cost of the device increases and the bulk of the device also increases.

In the combination weigher shown in FIG. 11, articles contained in a certain weighing hopper 5 or articles contained in a memory hopper 8 provided below the weighing hopper 5 are combined. If the item is selected, the article in the weighing hopper 5 is discharged and becomes empty, so that the article can be newly supplied to the empty weighing hopper 5 and the weight of the article can be weighed. Therefore, while the articles stored in the weighing hopper 5 or the articles stored in the memory hopper 8 provided below the weighing hopper 5 are not selected as a combination and are not discharged, the weighing hopper 5 is Since the weighing by is stopped, it is impossible to weigh a new article. Since there are a plurality of weighing hoppers 5 in which weighing is stopped at all times during operation of the combination weigher, there is a problem that the operating efficiency of the entire weighing hoppers 5 provided is low. .

Furthermore, in the combination weigher shown in FIG. 11, the articles selected for the combination are the weighing hopper 5 or the memory hopper 8.
Is discharged from the split chute 9 and the collecting chute 10
Since it is supplied to the packaging machine 12 through the inner wall surface of the product, it takes a long time to move through the path 13 for the adhesive or sticky article, whereby the weighed article is packaged by the packaging machine 12. There is a problem that it takes a long time to reach.

The present invention provides a high-speed processing method of a combination weigher and a combination weigher with a high-speed processing function, which can improve the weighing accuracy and weighing speed of the combination weighing of adhesive or tacky articles. To aim.

The rear end of the conveyor 64 is connected to the discharging device 65. Then, as shown in FIG. 3, the stopper 41 is provided at the rear end of the conveyor 64.
Is provided. This stopper 41 is a conveyor 64
The cup 20 conveyed to the rear end portion of the cup 20 is locked and stopped, and the standby position 4 at which the cup 20 stops
2 is the standby position according to claims 1 to 3. And
The transfer conveyor 64 is the standby transfer means described in claims 2 and 3. Further, according to the transport conveyor 64, the cup 20 sent from the staying conveyor 63 can be transported to the standby position 42 at a constant speed.

Next, the discharge device 65 will be described. The discharging device 65 is the discharging conveying means according to claims 2 and 3, and includes an inclined conveyor 91 and a sending conveyor 92, as shown in FIGS. 3 and 9. The delivery conveyor 92 is a plastic chain conveyor equivalent to the retention conveyor 63. The inclined conveyor 91 is a chain conveyor having a large number of cup holders 14 arranged in four rows on the conveying surface. This inclined conveyor 91 is connected to the conveyor 64 and is selected as a combination from the first to the first.
The cups 20 extruded by any of the tenth pushers 84-1 to 84-10 can be received by the four cup holding portions 14 one by one. However, when the number of the cups 20 selected for the combination is, for example, 3, 2, or 1, the cups 2, 3, or 1 of the cups 2 are selected.
0 can be received in order from the cup holding portion 14 near the stopper 41. The cups 20 received in the cup holding portions 14 are sequentially conveyed in an upward direction in a state where, for example, four cups are arranged in one horizontal row, and are inverted at the rising end to come off the respective cup holding portions 14 and the positioning cylindrical portion 15 It falls inside and stops at a predetermined discharge position 88. At the discharge position 88, the articles 21 accommodated inside are discharged from the cup 20 due to the fact that the cup 20 is reversed and the impact caused by the drop of the cup 20, and the funnel-shaped portion provided under the cup receiving plate 93. It is loaded into the packaging machine 89 through 16 and the loading port 94. And the four empty cups 20
The positioning cylinder portion 15 driven by the air cylinder 17 conveys the sheet to the delivery conveyor 92 side (direction of arrow 95 in FIG. 3). The four empty cups 20 are cup receiving plates 93
It is conveyed to the delivery conveyor 92 through the discharge port (not shown) provided in the above and the chute 18, is conveyed by this delivery conveyor 92, and is inverted by 180 ° by the cup reversing device 96, and the opening of the cup 20 is moved upward. It is sent out to the transfer conveyor 66 in the facing state. Then, the transfer conveyor 66 transfers the empty cup 20 to the transfer conveyor 6.
The empty cup pusher 70 is extended when the central processing unit outputs a predetermined supply signal as described above. Working, this empty cup pusher 70
The pad 71 provided at the tip of the above can send the four empty cups 20 on the terminal end 69 to the inlet on the loading stage 61. In this way, the cup 20 can be circulated to successively and sequentially perform the combined weighing of the articles.

It should be noted that the four, three, two, or one cups 20 containing the articles 21 forming each set selected as the combination are sequentially conveyed to the discharge position 88 shown in FIG. Then, the articles 21 in the cup 20 are sequentially loaded into the packaging machine 89. The packaging machine 89 reads from the storage means how many cups 20 accommodate the articles constituting one set, and reads 1 The articles that make up one set can be packaged in one pack.

Next, the combination calculating means takes out various combinations of the weights of the weighed articles 21 and calculates the combination, and the cup 20 containing the articles 21 selected for the combination is taken out from the stay conveyor 63. Transport conveyor 6
4 will be described. The procedure of moving the sheet 4 to the standby position 42 and then to the discharge device 65 will be described.

Although not shown in the figure, the combination calculation means is a calculation control unit (not shown) composed of a central processing unit (CPU) and a storage unit (not shown) connected to this calculation control unit. ) Is a means for performing a predetermined combination calculation. That is, each of the weighing devices 62-1, 62-2, 62-3, 6
When the weight of the article 21 put in the cup 20 is measured by the 2-4, the retention conveyor 63 shown in FIG.
Of a maximum of 12 cups 20 staying on the top, a predetermined number of tenths is preset from the first one (the predetermined tenth is the predetermined number Ath in claims 1, 2, and 3). The weight values of the weighed articles 21 contained in the respective cups 20 up to.) Are variously combined, and the number of the weight values constituting the set is 4 or less, and the total weight value is It is possible to select a weight value that constitutes a group within a predetermined weight range that satisfies a predetermined condition, for example, a group that is equal to or closest to the target weight value.

However, the combination calculating means, when the selection number B of the weight values selected for the combination is less than a preset predetermined number 4 (the predetermined number 4 is C in claim 1), The subtraction value (4-1 obtained by subtracting the selection number 1, 2, or 3 (= B) from the predetermined number 4 (= C) counting from the predetermined number 10th (= Ath) toward the head side = 3),
(4-2 = 2) or (4-3 = 1) th [= (C-
From the various combinations of weight values corresponding to the other cups 20 except the cups up to the B) th item, the number of weight values constituting the set is 4 or less, and the total weight value is predetermined. The weight values constituting the set within the predetermined weight range are selected.

Next, the operation procedure of the combination calculation means will be described with reference to the flow chart shown in FIG. First, when each of the four weighing devices 62-1, 62-2, 62-3, and 62-4 weighs the weight of the article 21 placed in each cup 21, the respective weight values are obtained (S200). ), Each weight of the articles 21 accommodated in each of the first to the predetermined tenth (= Ath) cups 20 among the cups 20 retained on the retention conveyor 63 shown in FIG. The values are variously combined, and among these combinations, the number of weight values constituting the set is 4 or less, the total weight value is within a predetermined weight range set in advance, and is equal to the target weight value, or Select the weight value that constitutes the closest group (S20)
2). However, when less than 10, for example, 9 cups 21 are retained on the retention conveyor 63, the above combination calculation is performed based on the weight values of the articles 21 accommodated in the 9 cups 20. Perform and select a predetermined combination.
Then, it is determined whether or not there is a selected combination in the combination (S204), and the selected combination exists in the combination, and YES.
When it is determined that it is determined whether the selection number B of the weight values forming the set selected in the combination, that is, the selection number B of the cup 20 is a predetermined number 4 (= C) ( S20
8). When the number B of the weight values that make up the selected group is four and YES is determined, as shown in FIG. 1A, the weight values corresponding to the four weight values are, for example, the first from the beginning. The fourth, sixth, eighth, and tenth four cups 20 are sent out from the staying conveyor 63 onto the transfer conveyor 64, and the four transferred cups 20 are transferred to the standby position 42 at the end of the transfer conveyor 64. Transport. At this standby position 42, the four cups 20 stand by in a row in a state of being pressed and pushed, and each of these cups 20 is ejected by the discharging device 6 as described above.
And the article 20 is discharged (S21).
0). It should be noted that, as shown in FIG. 1A, the tenth cup 20 moves to the standby position 42 and the transport conveyor 64.
The distance moved up is L ₄ . That is, L ₄ is the case where the number of selections B is 4 and the cup 20 moves to the standby position 42 on the conveyor 64 with the longest movement distance. Even if the number of selections B is 3, 2 or 1, this combination scale is subjected to the following processing so that the moving distance on the transport conveyor 64 for moving each cup 20 to the standby position 42 is L ₄ or less. The processing time of combination weighing is shortened.

That is, in step 208, if the number B of combinations selected is not 4 (C) but NO, it is determined whether the number B of combinations selected is 3 (S2).
12) If there are three and YES is determined, it is determined whether or not the tenth cup 20 is included in the three cups 20 corresponding to the selected three weight values ( S214). The tenth cup 20 is designated as this determination criterion is that the subtraction value 1 is obtained by calculating 4 (= C) -3 (= B) = 1, and the predetermined number 10th (= Ath)
This is because the first subtracted cup 20 (that is, the tenth cup 20) is not selected.
Therefore, the tenth cup 20 is not included, and NO
If it is determined that, as shown in FIG. 1B, the three cups 20 corresponding to the three weight values, for example, the fifth, seventh, and ninth cups 20 from the beginning are conveyed from the retention conveyor 63. The sheet is sent onto the conveyor 64 and is conveyed to the standby position 42 at the end of the conveyor 64. The articles 20 are discharged from the respective cups 20 standing by at the standby position 42 by the discharging device 65 (S210). In addition, the moving distance on the transport conveyor 64 by which the ninth cup 20 moves to the standby position 42 is L ₄ as shown in FIG. 1B. Since the movement distance L _{4 of} the ninth cup 20 is the maximum movement distance when the selection number B is 3, the movement distance when the selection number B is 3 is the maximum movement distance when the selection number B is 4. It is possible to prevent it from becoming longer than the maximum movement distance L ₄ .

However, when the number of selections B is three, the tenth cup 20 is included in the three cups 20 corresponding to the selected three weight values, and Y is selected in step 214.
When it is determined to be ES, a combination calculation is performed based on the nine weight values corresponding to the first to ninth cups 20 (S
216), and returns to step 204 to perform the same processing as above. That is, when the number of selections B is 3, the first of the three cups 20 corresponding to the selected three weight values is first.
When the three cups 20 are sent to the side of the conveyor 64 when the 0th cup 20 is included, the movement distance of the tenth cup 20 on the conveyor 64 is as shown in FIG.
As shown in (b), it becomes L ₃ , which is longer than L ₄ by L _0. Therefore, in order to avoid this, other than the weight value corresponding to the 10th cup 20, the 1st to 9th cups are excluded. The combination calculation is performed based on the nine weight values corresponding to the cup 20 of FIG.

Similarly, in step 218, it is determined that the combination selection number B is 2, the selection number B is 2, and Y
When it is determined to be ES, it is determined whether or not the ninth and tenth cups 20 are included in the two cups 20 corresponding to the selected two weight values (S220).
If the ninth and tenth cups 20 are not included and it is determined to be NO, as shown in FIG. 1C, for example, the sixth and eighth from the beginning corresponding to these two weight values. The two cups 20 from the retention conveyor 63 onto the conveyor 6
4 and conveys the articles 20 to the standby position 42 at the end of the conveyor 64, and ejects the article 20 from each cup 20 by the ejection device 65 (S210). The eighth conveyer cup 64 moves the cup 20 to the standby position 42.
The moving distance above is L ₄ , as shown in FIG.
It is possible to prevent it from becoming longer than the maximum moving distance L ₄ when the number of selections B is four.

However, when the selection number B is two, the two cups 20 corresponding to the selected two weight values include the ninth or tenth cup 20, and at step 220. If YES is determined, a combination calculation is performed based on the eight weight values corresponding to the first to eighth cups 20 (S222), and the process returns to step 204 to perform the same process as above. As a result, when the selection number B is two, the movement distance of the cup 20 on the transport conveyor 64 is shown in FIG.
As shown in (c), it can be set to L ₄ or less.

Similarly, when it is determined in step 218 that the number B of combinations to be selected is 1 instead of 2, one cup 20 corresponding to the selected one weight value corresponds to the eighth and ninth cups. , The tenth cup 20 is determined (S224). 8th, 9th, 1st
When it is determined to be NO instead of any of the 0th cups 20, as shown in FIG. 1D, for example, the 7th cup 20 from the top corresponding to this one weight value is placed on the stay conveyor 63. From the transfer conveyor 64 to the standby position 42 at the end of the transfer conveyor 64, and the discharging device 65 discharges the article 20 from the cup 20 (S210). The moving distance on the conveyor 64 for moving the seventh cup 20 to the standby position 42 is L ₄ as shown in FIG. 1D, and the maximum moving distance when the number of selections B is four. It can be no longer than L ₄ .

However, when the selection number B is one, one cup 20 corresponding to the selected one weight value is one of the eighth, ninth and tenth cups 20. Yes, if YES is determined in step 224, the first
~ A combination calculation is performed based on the seven weight values corresponding to the seventh cup 20 (S226), and the process returns to step 204 to perform the same process as above. As a result, the number of selections B
When the number of cups is 1, the moving distance of the cup 20 on the conveyor 64 can be set to L ₄ or less as shown in FIG.

However, in step 204, when the number of the weight values constituting the set is 4 or less and the total weight value does not exist within the predetermined weight range and there is no combination, it is determined as NO in FIG. 1 to 1 on the conveyor 64 shown in FIG.
12 cups in total, 0th, 11th and 12th
A combination calculation is performed using the weight values of the articles 21 stored in 0 (S206), and there is a combination in which the number of weight values forming the set is 4 or less and the total weight value is within the predetermined weight range. It is determined whether or not to perform (S204), and the same processing as above is performed. . When the weight value corresponding to the eleventh or twelfth cup 20 is selected as the combination,
First, the cups 20 selected as a combination among the first to tenth cups 20 are sent out to the conveyor 64 side,
Then, when the eleventh or twelfth cup 20 is conveyed by the staying conveyor 63 and moves to the front of the pusher 84 and stops, the eleventh or twelfth cup 20 is sent to the conveying conveyor 64 side. .

Thus, the selection number B is the predetermined number 4 (= C).
When it is smaller, the transport distance (transport time) on the transport conveyor 64 that transports the cup 20 to the standby position 42 is the transport distance L ₄ (transport time) when the selected number B is the predetermined number 4 (= C). It is possible to prevent it from becoming longer than that, and as a result, it is possible to prevent a decrease in the weighing processing speed of the combination weigher. As described above, since it is possible to prevent a decrease in the weighing processing speed of the combination weigher, it is possible to achieve a higher weighing processing speed of the combination weigher.

However, although 10 pushers 84-1 to 84-10 are provided along the retention conveyor 63, the number may be other than 10. For example, 12 pushers 8
When 4-1 to 84-12 are provided, the retention conveyor 63
The number 12 of the weight values of the articles put in each of the 12 cups 20 arranged in one row above is the predetermined number A. Therefore, in the combination calculation of step 202, the weight of these 12 (predetermined number A) is A combination operation is performed based on the value. Then, when the predetermined number A is 12, it is determined in step 214 whether or not the weight value corresponding to the twelfth cup 20 is included in the selected combination, and in step 216, the first to eleventh values are determined. The combination calculation is performed based on the weight value corresponding to the cup 20 of FIG. And step 22
At 0, it is determined whether or not the weight values corresponding to the eleventh and twelfth cups 20 are included in the selected combination, and at step 222, the first to tenth cups 2
A combination calculation is performed based on the weight value corresponding to 0. Further, it is determined whether or not the cup 20 corresponding to the weight value selected for the combination in step 224 is any of the tenth, eleventh and twelfth cups 20, and in step 226, the first to the first A combination calculation is performed based on the weight value corresponding to the ninth cup 20. As a result, similarly to the above-described embodiment, it is possible to achieve a high weighing processing speed of the combination weigher.

Although the maximum number C of the weight values selected for the combination is set to 4, it may be set to a number other than this. When the maximum number C is, for example, three, and when the combination selection number B is three, any one of the first to tenth cups 20 can be sent to the transport conveyor 64 side. , And when the number B of combination selections is 2, any one of the cups 20 of the first to ninth cups 2
0 is sent to the conveyor 64 side, and when the number of combinations B selected is one, one of the first to eighth cups 20 is sent to the conveyor 64 side.

Next, the start of the combination calculation of the combination calculation means will be described. The combination calculation by the combination calculation means is
The operation is started when the operator operates the setting display unit 87 and the preset number of combination calculation start memories reaches K. The combination calculation start memory number is a condition for the combination calculation means to start the combination calculation, and this condition is the number of cups 20 stopped on the stay conveyor 63 (the weighing stored in the storage unit). It is assumed that the number of weight values of finished articles) is, for example, K = 9 or more. In other words, if the number of weight values stored in the storage unit is less than 9, even if the combination calculation is performed, it is unlikely that a combination whose total weight falls within the predetermined weight range is selected. When the number of values becomes 9 or more and the possibility of selecting a combination becomes high, the combination calculation is performed. However, this combination calculation start memory number K can be set by the operator by operating the setting display section 87 according to the weighing accuracy of the combination weighing and the weighing speed. Then, when the number of the cups 20 stopped on the staying conveyor 63 becomes less than 9, the weigher 62 stores the weighed articles until the number of the cups 20 on the staying conveyor 63 becomes 9 or more. 4 cups 20
They are delivered individually. When the number of the cups 20 on the staying conveyor 63 becomes 9 or more, the weighing device 6
The transport from 2 stops automatically.

Next, as a predetermined combination of articles (weight values) by the combination calculation means, for example, as shown in FIG.
Taking out the cup 20 will be described by taking as an example the case where the twenty-first article 21, the fifth article 21, the eighth article 21 and the tenth article 21 are selected. As shown in the figure, the second, fifth, eighth, and tenth pushers 8
4-2, 84-5, 84-8, 84-10 are driven to extend, so that the cups 20 for accommodating the second, fifth, eighth, and tenth articles 21 are placed on the retention conveyor 63. Push it out to get over the upper surface 81 of the holding frame 79,
It can be moved to a transfer conveyor 64 provided adjacent to the staying conveyor 63. Then, the second, fifth, eighth, and tenth pushers 84-2, 84-
As shown in FIG. 4, the pads 85 provided on the pushers 85, 84-8, and 84-10 are driven to extend.
-2, 85-5, 85-8, and 85-10, the respective locking plates 86, respectively, to the succeeding cups 20 of the respective second, fifth, eighth, and tenth cups 20 taken out. Can be locked. As a result, the second, fifth, eighth, and
And tenth pushers 84-2, 84-5, 84-
8, 84-10 when each pad 85-
2, 85-5, 85-8, 85-10 can smoothly return to the original position shown in FIG. 3 without hooking the subsequent cups 20.

Then, the second, fifth, eighth, and tenth four cups 20 moved onto the conveyor 64.
Are transported by the transport conveyor 64 and discharged from the discharge device 6
5. The second conveyed to the discharge device 65,
Each of the fifth, eighth, and tenth cups 20 includes the article 2
1 is taken out, and the taken-out article 21 is packed by the packing machine 89. On the other hand, the second, fifth, eighth, and tenth
Pushers 84-2, 84-5, 84-8, 84-1
When 0 is shortened, the first, third, and
The six cups 20 for accommodating the fourth, sixth, seventh, and ninth articles 21 and the subsequent two cups 20 are conveyed by the stay conveyor 63 and moved forward. Also, 4
The four cups 20 containing the weighed articles are sequentially supplied to the staying conveyor 63 from the weighing machine 62 of the table. These four
The individual cups 20 and the eight cups 20 on the staying conveyor 63, that is, a total of twelve cups 20 containing the weighed articles, are conveyed to the top cup 2 as described above.
0 is locked by the stopper 73, and the top cup 2
0 and the subsequent cups 20 are stopped in a row on the retention conveyor 63 in a state of being pressed against each other. After that, the following combination calculation is performed.

However, when the number of articles (weight value) 21 selected by the combination calculation is 4, only eight cups 20 remain on the staying conveyor 63, so the combination calculation start memory number K = 9. Less than one, and therefore the cup 2 into which the next weighed item has been loaded from the four weighing devices 62
The following combination calculation is not performed until 0 is discharged to the staying conveyor 63. However, for example, assuming that 12 cups are staying on the staying conveyor 63,
The number of articles (weight value) 21 selected by the combination calculation is 3
When the number is less than or equal to 9, since nine cups 20 remain on the staying conveyor 63, the number of combination calculation start memories K = 9.
Therefore, the cup 20 in which the next weighed article is loaded is not supplied from the weighing device 62 to the staying conveyor 63. As a result, a combination calculation can be performed before the next cup 20 is supplied from the measuring device 62 to the staying conveyor 63. As described above, the reason why it is not necessary to wait for the arrival of the cup 20 in which the next weighed article 21 is stored is 11 from the top on the retention conveyor 63 shown in FIG.
The second cup and the twelfth cup 20 are waiting,
This is because the weight values of the articles accommodated in the two cups 20 can participate in the next combination calculation.

Next, with reference to FIG. 10, a procedure for storing the weighed weight of the article will be described. First, the weighing of the cup 20 into which the article is put is completed by the weighing device 62 (S
100), the weight value of this weighed article is stored in the storage unit (S102, 104). For example, the first, second, ...
The weight value obtained by measuring the N-th is the first, second, ...
., Store in Nth memory. Then, it is determined whether or not the number of stored weight values is K, for example, 9 or more (S106), and when it is determined that the number is less than 9, the combination calculation is not performed, and 9 or more is performed. When it is determined that there is,
A combination calculation is performed (S108). Then, the s weight values (M _l , M _m , _... ) Selected for the combination by the combination calculation.
The cup 20 containing the articles of M _n ) is pushed out to the conveyor 64 (S110).

However, since the articles left on the staying conveyor 63 without being selected are sequentially advanced and the order of the articles is changed, it is necessary to change the order of the weight values stored in the memory. Therefore, M _{n + 1} , M _{n + 2} , ..., M
_The weight value stored _{in the n + (in)} th memory is M _n ,
_{M n + 1, ····, M} n + (in) respectively were transferred replacing the _-1st memory (S112). And M _{m + 1} , M _{m + 2} , ...
The weight value stored in the M _{m + (im)} th memory is transferred to the M _m , M _{m + 1} , ..., M _{m + (im) -1} th memory (S114). Also, M _{l + 1} ,
The weight value stored in the M _{l + 2} , ..., M _{l + (il)} th memory is M _l , M _{l + 1} , ..., M _{l + (il) -1.}
The data is transferred to the second memory (S116). In addition, 1
.Ltoreq.l <m <... <n.ltoreq.i, where i is the maximum numeric value of the stored memory numbers.

Then, s is subtracted from the original number i of weight values stored in the memory to calculate the number i of weight values currently stored (S118). In this way, it is possible to store the weight value obtained by newly weighing the articles in sequence, and to store in each memory in accordance with the change of the order of the articles remaining on the stay conveyor 63 without being selected. The order of the stored weight values can be sequentially changed. Thereby, each weight value of the article stopped on the stay conveyor 63 can be stored in association with each article.

According to the combination weigher of the above-described embodiment, as shown in FIG. 3, after the article 21 to be weighed is put into the cup 20 on the input stage 61, it is selected by the combination calculation and used for the packaging of the packaging machine 89. The same cup 20 holds the article until it is put into the bag. Therefore, the sticky or tacky article does not stick to the inside of the split chute 9 or the collecting chute 10 as in the conventional combination weigher shown in FIG. It is possible to improve the weighing accuracy and the weighing speed of the combined weighing of articles such as cut vegetables, pickles, or streaks having the above.

Then, a large number of cups 20 into which weighed articles have been put can be stored on the staying conveyor 63, and a large number of articles put into these many cups 20 to stay can participate in the combination. Since this is a configuration that can be performed, the weighing accuracy of the combination weighing can be improved also by this. In addition, in the case of increasing the number of articles that can participate in the combination, it is possible to increase the length of the staying conveyor 63 and the conveying conveyor 64 and increase the number of pushers 84.
Unlike the combination weigher shown in (1), it is economical because it is not necessary to increase the number of sets of the linear feeder 3, the weighing hopper 5, and the memory hopper 8 in order to increase the weight value of the article by one.

Moreover, since a large number of weighed articles can be stored without transferring the articles put in the cup 20 to another hopper or the like, it is possible to transfer the articles to another hopper or the like. Since there is no change in weight due to the adhesion caused by the above, the weighing accuracy and the weighing speed of the combined weighing of articles having adhesiveness can be improved more than ever before. Since the cups 20 containing a large number of weighed articles can be stored on the staying conveyor 63, the weighed cups 20 can be sequentially discharged from the weighing device 62, whereby It is possible to continuously carry out the weighing by the measuring device 62, and as a result, it is possible to improve the operation efficiency of the measuring device 62 as compared with the conventional case.

However, in the above embodiment, when the weight of the empty cup 20 is unknown, or when the weight of the empty cup 20 varies widely, a separate weighing machine is provided in front of the loading stage 61 and the weighing machine is used. The weight of the empty cup 20 may be preliminarily measured, and the weight of the corresponding cup 20 may be subtracted from the total weight of the cup 20 and the article 21 obtained by weighing with the weighing machine 62 in the subsequent stage to obtain the weight of the article 21. Good.

When the weight of each empty cup 20 is uniform, the total weight of the cup 20 and the article may be variously combined to perform the combination calculation. In this case, the target weight value is the weight value of the weight of the article 21 plus the weight of the cup 20.

Although the cup 20 has a short cylindrical shape having a bottom, it may have a shape other than this, for example, a polygonal cylinder having a bottom.

Further, the staying conveyor 63 of the above embodiment,
Although each of the transport conveyors 64 and the transport conveyor 64 has two annular plastic chains, it may have, for example, one annular plastic chain. In short, the retention conveyor 63 and the transfer conveyor 6
Each of the conveyors 4 can convey the cup 20 in a predetermined direction, and when the leading cup 20 is stopped and stopped while the conveyor surface of the conveyor is moving (during driving). Any structure may be used as long as the succeeding cup 20 can be pressed and stopped on the conveying surface of the conveyor.

[0060]

According to each of the first to third aspects of the invention, from the time the article to be weighed is loaded into the article holding means at the loading stage until it is selected by the combination calculation and conveyed to the discharge position and discharged. The article is held by the same article holding means. Therefore, in the conventional combination weigher shown in FIG. 11, when weighing an adhesive or adhesive article, the article may adhere to the inside of the split chute 9 or the collecting chute 10, but according to the present invention, Since it is not necessary to provide the dividing chute 9 or the collecting chute 10 in the combination weigher, such adhesion can be completely eliminated, and as a result, the weighing accuracy and weighing of the combination weighing of the adhesive or sticky articles can be achieved. There is an effect that the speed can be improved more than before.

Moreover, since the article holding means is conveyed to the article discharging position without moving the article loaded in the article holding means to another hopper or the like, the article is moved to another hopper or the like. There is no weight fluctuation due to the adhesion caused by this. This also has the effect that the weighing accuracy and the weighing speed of the combination weighing of articles having adhesiveness can be improved more than ever.

According to the present invention, when the selection number B of the weight values selected for the combination is less than the predetermined number C, the predetermined number A from the top of the article holding means on the staying means is counted from the top. Toward the subtraction value (C−B) th obtained by subtracting the selection number B from the predetermined number C when counting toward various article holding means other than the respective article holding means. The combination calculation means selects the weight values that form a set of which the total weight value falls within a predetermined weight range from among the combinations. As a result, the selected number B is the predetermined number C
When the number is smaller, the conveying distance (conveying time) for conveying the article holding means to the standby position can be prevented from being longer than the conveying distance (conveying time) when the selected number B is the predetermined number C. As a result, it is possible to prevent a decrease in the weighing processing speed of the combination scale when the selected number B is less than the predetermined number C. In addition, since it is possible to prevent the reduction of the weighing processing speed of the combination weigher as described above, it is possible to achieve a higher weighing processing speed of the combination weigher.

Further, the article holding means for containing the weighed articles weighed by the weighing means is sequentially sent out from the weighing means, and the article holding means for accommodating a new article to be weighed is sequentially conveyed to the weighing means. It is a configuration. As a result, the weighing means can continuously weigh the weight of the article holding means that accommodates the articles to be weighed, without interruption, and as a result, the operating efficiency of the weighing means (the time during which the combination weigher is in operation). It is possible to improve the ratio of the time during which the measuring means performs the measurement) to that of the conventional method.
