Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a sorting and packaging device for sorting and packaging eggs such as chicken eggs.

(Conventional technology) Chicken eggs are classified into SS (40g) according to the trade standards of the Ministry of Agriculture, Forestry and Fisheries.
or more and less than 46g), S (46g and less than 5211), M
S (52g to less than 58g), M (58g to less than 64g)
, L (64 g to less than 70 g), 2 L (70 g to less than 76 g), and non-standard (76 g or more) are packaged and sold in plastic containers, for example, in units of 10. In such packaging, the weight of the eggs to be packaged,
That is, the egg weight is measured, the egg weight is used to sort out which of the weight categories the eggs belong to, and based on the sorting results, the eggs are put into containers, for example, every 10 eggs, corresponding to the 1i weight category. A sorting and packaging device is used for packaging. Also-
A sorting and packaging device that presets upper and lower limits of egg weight of eggs to be selected for packaging, and sorts and packs eggs within these upper and lower limits without being restricted by the weight category. has also been proposed.

(Problems to be Solved by the Invention) By the way, in the latter sorting and packaging apparatus, - When sorting eggs for packaging from a plurality of eggs, the weight of the previously selected egg and the weight of the newly selected egg are determined. It is checked whether the total weight with the weight of the previously selected egg is within the weight range set in relation to the weight of the previously selected egg, and if it is outside the weight range, the egg to be newly selected is is removed from the selection and the eggs from the pond are selected as the newly selected eggs to perform the above inspection, but in such a sorting and packaging device,
A relatively large number of eggs are excluded from selection, making it difficult to obtain a sufficiently high production rate of packaged products.

The present invention has been made in view of the above points, and it is possible to select eggs without being restricted by weight categories within preset upper and lower limits so that the total weight of one package is a constant value. To provide a sorting and packaging device that can reduce the number of eggs excluded from selection and improve the production rate of packaged products when packaging eggs.

(Means for Solving Problems) According to the present invention, the object is to provide a means for weighing eggs to be supplied, a means for storing a plurality of egg weights weighed by the weighing means, and a means for storing a plurality of egg weights weighed by the weighing means. a program that determines whether to store eggs corresponding to the egg weight stored in a packaging line or a standby line by a means that performs a calculation, a program that calculates to obtain a set weight of one packaging unit, and a program that performs a calculation and a program that performs the calculation. control means for controlling said eggs between a packaging line and a waiting line on the basis of the results; and a replenisher provided for replenishing a container with eggs that have already been determined as one egg of a package according to instructions of said control means. This is achieved by an egg sorting and packaging apparatus comprising means and, if necessary, a discharge means for taking out eggs stored in containers on the packaging line.

(Specific Example) Next, the present invention will be explained based on a preferred specific example shown in the drawings.

FIG. 1 is a schematic diagram of a preferred embodiment of the present invention, FIGS. 2 and 3 are partial detailed views of the embodiment shown in FIG. 1, and FIG. 4 is an electrical block diagram of the embodiment shown in FIG. 1121. , FIG. 5 is an explanatory diagram of the bad memory condition of the storage device shown in FIG. 1.

At the mouth, the scale 1 sequentially measures the weight of eggs 2 fed from the input direction by a conveying device or manually. In this specific example, the scale 1 measures the weight of eggs 2 fed in parallel in six rows. Although six eggs are provided for weighing, the present invention is not limited to this, and in the case of eggs supplied in one row, only one egg is required. Grip part 4 of W3
are held in sequence and conveyed in a single line in the B direction. Measuring instrument 1
The respective weights of the eggs 2, that is, the egg weights, are stored in the storage device 6 in the same order as the order in which the eggs 2 were transported under the control of the control device 5 comprising a microcomputer or the like. Here, the same order is not limited to the physically same order, but the point is that it is sufficient to obtain a correspondence between the stored egg weight and the position of the egg in the transport device 3 indicating this egg weight. is an illustration of the memory shape.

The storage position P of the egg weight W stored in the storage device 6 in the order of transportation is shifted by one each time the egg weight is sequentially input to 21).
-L, and at the same time the mark marked on each egg weight also shifts. This mark is determined by the execution result of a program to be described later, and based on this mark, the control device 5 performs control to sort the eggs. The conveying device 3 includes, for example, the above-mentioned gripping section 4 and an endless chain 7 to which the gripping section 4 is attached and which moves the gripping section 4 in the direction B.
The motor 8 is connected to an encoder 9 that detects the amount of travel of the endless chain 7, in other words, the amount of travel of the grip portion 4. The amount of travel to be done is
It is supplied to the control device 5. The control device 5 executes a program to be described later, and controls the packaging line 10 based on the execution result.
The opening mechanisms 19 to 27 and the drive mechanisms 28 to 36 provided corresponding to 18 are activated, respectively, and the egg weight from the weighing device 1 and the normal and abnormal egg signals from the egg checker (not shown) are transmitted. Then, it instructs the storage device 6 to store the egg weight, etc. ! Each of the release mechanisms 19 to 27 releases the egg 2 that has arrived on the packaging line corresponding to the release mechanism from the gripping section 4 in response to a release command from the control device 5. The released egg 2 is on the packaging line &! 2S37, which is a plastic container that can hold 10 pieces. Each of the driving machines 41128 to 36 moves each belt conveyor of the packaging lines 10 to 18 a half step or a full step in response to a half step or full step command from the control unit 5. System (1 load, half step forward command from 2f5 completes loading eggs on the 1st row side of container 2237,
Container 37 is used to charge eggs to the other row side.
Approximately half of the movement is carried out by a belt conveyor,
In the full step command, the belt conveyor moves approximately between the two containers in order to complete the loading of eggs into the two rows of containers 37 and to begin loading eggs into the primary container. In this specific example, containers 37 capable of packaging a total of 10 eggs, 5 in each row, are used, but the present invention is not limited to this.In the packaging line 10, eggs are packaged for weight class SS. In the packaging line 11, the eggs are packaged for the ffi quantity classification S, and in the packaging line 12, eggs that are within a predetermined range are successively packaged in 10 eggs, among the eggs that are conveyed in the order of weighing.
When the total weight of successive eggs satisfies the 3q constant angle or the set overlapping range, the eggs are stored in the container 2-37 placed on the packaging line 12 at the packaging position. In the packaging line 15, the eggs are packaged for 2L gL quantity category, in the packaging line 16, the eggs are packaged in the weight category, and in the packaging line 17, eggs are packaged in 1 weight category M.

In the packaging line 18, packaging is performed for each weight class MS, and in the packaging line 13, packaging according to the present invention is performed.

Line 14 is a standby line in which rabbits excluded from the three choices are kept on standby as required. The standby line 14 is within a predetermined overlapping range and il! It has a continuous container 38 in which eggs excluded from selection are regularly and sequentially conveyed. Therefore, the container 38
When moving, the rainbow driving mechanism 32 of the timing line 14 advances the waiting line 14 by a half step in response to a half step from the control device 5. By the way, the storage seat of the container 38 placed on the waiting line 14 is It is in a grid pattern, with an X.

The location can be easily specified by assigning the Y coordinate. Further, an exchange area 39 is set as an area from which the eggs housed in the container 38 can be taken out. 9. At the top of the packaging line 12. There is a pallet 40 for blushing the parched eggs, which pallet 40 is grid-shaped with receiving seats of the same size as the containers 38, and the containers 37 placed on the mixing packaging line 13.
The containers 38, the containers 37 on the mixing packaging line 13 and the pallets 40 have X, Y coordinates. ), each part of one matrix. Then, on a line parallel to the X axis and on both sides of the mixing packaging line 13, between the waiting line 14 and the container 38 on the waiting line 14, the eggs stored in the containers 38 on the waiting line 14 are taken out, and the containers on the mixing packaging line 13 are A replenishment arm equipment 41 for replenishing the 2S37 takes out the eggs in the container 37 placed on the mixing packaging line 13' between the packaging line 12 and the pallet 40.
An ejector arm device 42 is provided for receiving the ejector. As mentioned above, the replenishment arm device 41 and the 1JF arm device W 42 t-1;'-c-, the line is X, Y1'MW

The eggs attracted to the suction cups 44 provided at the tips of the arms 43 are transported by rotation, expansion and contraction of the arms 43 of the replenishment arm device 41 and the discharge arm device 42. A schematic side view of the replenishment arm device 41 and the IJi output arm device 42 is shown in No. 3I71. The position determination of the replenishment arm device 4] and the ejection arm device 42 is disclosed in Japanese Patent Application Laid-Open No. 61-78476 and Japanese Patent Application Laid-open No. 6]78477, and the operation based on the control is disclosed in Japanese Patent Application No. 59-1.
50169 and Japanese Patent Application No. 120573 of 1983, and since known devices can be used, the details will be omitted. Anyway, the said supplementary arm W/11. ．． and I.J.
The first arm device 42 is operated by a command from the control device 5 based on the calculation results of an exchange program to be described later.

Replenishes and discharges eggs.

Based on a specific example consisting of five or more LIJ colors, eggs within a predetermined range, in this example, egg weights from 32g to less than 76g, are sequentially transferred to the needle M.
After counting i in the container 1, 10 eggs are determined as mixed packaging eggs in the order of conveyance, and after being stored in the container 37 on the mixing packaging line 13, the eggs are replaced with the eggs stored in the container 38 on the standby line 14. This embodiment discloses the case of obtaining mixed packaging with a set weight or within a set weight range.This embodiment is a case in which eggs are replaced once, and will be explained based on the drawings. FIG. 6 is a plan view showing the outline of this embodiment,
FIG. 7 is an explanatory diagram of the memory condition of the storage area E where the egg weights stored in the storage positions P in the order of conveyance are sequentially examined on the weighing pan after the needle Jl, and FIG. This is the flow of the selection program, and FIG. 8 is the flow of the exchange program.

The operation of the egg sorting and packaging apparatus 50 in this embodiment will be explained with reference to a flowchart. First, in step 51, the control device 5 sends an opening command to the opening mechanisms 19 to 27;
Sending a half step command or a full step command to the drive mechanisms 28 to 36, sending an operation command to the replenishment arm device 41 and the discharge arm device 42, reading one egg weight from the scale 1,
Then, the read egg weight is stored in the storage device 6, information on whether the egg is normal or not is read from the egg incubator, and the traveling distance is read from the encoder 9. In step 52, as a result of reading the traveling distance from the encoder 9, it is checked whether the gripping parts 4 have traveled one unit distance, that is, the distance M between the gripping parts 4, and if they have not advanced by the distance l, Returning to step 51, when the distance l has progressed, in step 53, the weight of the eggs that have been weighed sequentially is once
It is input into the judgment area E in the storage device 6. In step 54, it is determined whether the egg weight input into the judgment area E is less than 52 tr to 76 g, which falls within a predetermined range as condition 1. If condition 1 is satisfied, the egg is shifted to selection area E1 to EIO El, and if condition 1 is not satisfied, the egg is marked to be put into a packaging line corresponding to the egg weight in step 55. By the way, judgment area E
By shifting the egg weight from Elo to the selection area El, the egg weight stored in this Elo pushed out from Elo has already been transferred to the exchange area E (1) in the storage device 6 at this stage.
, 1) to E(6,5), or shifted to calculation areas Ell to E20, or eggs to be packaged in a separate packaging line 12, or in a subsequent grade packaging line. It has been determined which eggs are to be packaged. Thereafter, the process returns to step 51 to read the next egg weight. In step 56, the egg weights sequentially shifted from the judgment area E are input into all of the selection areas E1 to EIO, and the egg weight of 10 eggs is determined in the 8 selection areas where it is judged whether the number of eggs reaches 10 pieces as one packaging unit. If loaded, 0 condition 2 determines whether the total value of the 10 egg weights input in the selection areas E1 to EIO in step 57 satisfies the set weight or set weight range as condition 2. If the above is satisfied, in step 58, the 10 egg weights input in the selection areas E1 to EXO are marked as eggs as one packaging unit, and the eggs corresponding to this egg weight are separately provided as mixed packaging eggs. i! on packaging line 12. ! It is put into the container 37 placed there. Naturally, the total egg weight of the eggs contained in this container 37 satisfies the set weight or set weight range. Selection area E] ~ E Once the egg weight in 10 is determined and marked as one packaging unit of mixed packaged eggs, in step 5, the egg weight Loft in the selection area is set! i
All t are paid out by shift, and E1 to E1-
Empty the memory of the 0 selection area. Then, the process returns to step 51 to read the next egg weight. If condition 2 is not satisfied in step 57, it is determined in the next step 60 whether egg weights have been input for all 130 ring ffs in exchange areas E(1,1) to E(6,5). . If all 30 eggs are not stored, the egg weights are input from E to El by shift in step 61, and the egg weights stored in EIO are input sequentially from column 1 to row by row in the exchange area. go.

Then, the process returns to step 51 to input the next egg weight. When it is found in step 60 that all egg weights are stored in the exchange area, that is, exchange area 3 on the standby line.
When it is determined that eggs are contained in all three containers 38, in step 62, eggs are shifted to calculation areas Ell to E20 in order to obtain one packaged unit of eggs, and sequentially stored. Egg weights that exceed the shift from E20 are processed based on the calculation results. Then, in step 63, it is determined whether the weight of eggs in calculation areas Ell to E20 has reached 10. If the egg weight is not yet 10, the process returns to step 51 to input the next egg weight.

When 10 eggs are input into the calculation area, in step 64, the egg weights stored in the three containers 38 of the exchange area of the standby line 14, that is, the exchange areas E(1,1) to E(6,
5) Select one egg by calculation from the egg weight stored in step 5) and replace it with the egg in the container 37 waiting on the mixing packaging line 13, and mix packaging as one packaging unit that satisfies the set weight or within the set weight range. Make it into eggs. Then, in order to determine the next packaging unit, the egg weights in calculation areas Ell to E20 are shifted and the memory is emptied.

By the way, the storage location P in the storage device 6 is a judgment area E for determining the egg weight stored in the storage location P;
Continuing selection areas E1 to EIO1 calculation area E
ll~E20, exchange area E(1,1)~E(6,5>
The sorted and marked egg weights are discharged from each area, and the type of mark is stored in the mark position in the storage position P, and based on this memory, the control device 5 controls the replenishment arm device. 41 and the ejection arm device 42. In addition, the control device 5 can control other devices by the method disclosed in Japanese Patent Application No. 61-47777.

Next, the calculation process of the exchange program executed in step 64 will be explained. First, in step 65, the calculation area Ell
- Add up the egg weights input in E20.

In other words, the egg weight input into Ell~E20 is n(1),
When n(2) and -n(10), the egg weight scale is n(1
)+n(2)+・・・・・・+1(1-0)=Σn(i
> becomes.

(However, i-1,..., 10) Then, in step 66, the difference between the total egg weight Σn(i) and the set weight is 52g to 76i, which is within the predetermined range of this embodiment.
Determine whether the difference in egg weight is less than r, within ±24 g.

That is, −24<(Σn(i) −M )<24
(where M is the set weight).

If −24<(Σn(i) M)<24 is not satisfied, in this example, the number of exchanges is set to one in order to process faster, and one exchange, that is, exchange of one egg weight, Assuming that the set weight cannot be obtained, the E20 egg weight is marked for input into the grade packaging line in step 67. Then, in step 51, jump to read the next egg weight. -24 (Σn(i) -M) < 24, in step 68 each egg weight n(1) to n(10) of E11 to E20 is replaced with an egg weight of 8 to obtain the set weight. It is calculated for each of n(1) to n(10) whether the following is satisfied.

That is, -max n(i)-(Σn(i)-M)=f
It can be expressed as (i>(i-1,..., 10).

Next, in step 6, when the set weight range is a to b, the formula for calculating what range of egg weights n(1) can be exchanged with is the most suitable formula % formula % ))) and the minimum value (n(i) −(Σn(i) −−)
l as gl(i) maximum value 1n(i>-(Σn(i)-bN
By dividing g2(i) and a IA, we get (i>-(Σn(i)-a)=gl(i)n(i
>-<Σn(i)-b)=g2(i).

Then, the egg weight E (L, h) in the exchange area L row, h column
satisfies the replacement egg weight f(1) corresponding to each n(i) calculated based on the egg weight of Ell to E20, or the egg weight of the replacement egg weight range gHi) to g2 (i). In order to make a decision, first in step 70 E (
Determine whether t, h) = f(i). In other words, the egg weight E (t, h) in the exchange area, row, h column.
and ``(i), and if they do not match, then in step 74, it is determined whether gl (i) to g2(i) are satisfied.In step 70 and step 711, if the respective conditions are satisfied, In step 71, the egg weight E (t, h) in the exchange area is registered as an exchange egg, and in step 72, the egg weight of the egg that is removed when stored in the container is registered as a discharged egg.Then, the next packaging unit is To determine, shift the egg weight in the calculation area and
~Empty E20's memory.

By the way, if step 70 or step 74 cannot be satisfied, step 75 checks whether all E(t, h) have been tested. In other words, the exchange area to be tested is E(1, 1) in the first row and first column. 1st row, 2nd column E(1
, 2), 3rd column E (1°3) in the 1st row... 1 in the 2nd row
Column E (2, 1), ... 5th column E (6, 5) in the 6th row
If not, in step 76 the position of E(t,h) is advanced by one in the above order, and in step 70 it is jumped. E(1
, 1) to E(6, 5), but if a satisfactory egg weight cannot be obtained, in the next step 77, the waiting line 1
4 can be walked half a mile. That is, E(1,1) to E(1,5
> egg weight is pushed out from the exchange area, and E(2,1)~
E(2,5> goes from E(1,1) to E(1,5>...E
(6,1)~E(6,5) is E(5,1)~E(5,5)
), and the memories of E(6,1) to E(6,5) become empty. Regarding the container 38 on the standby line 14, by moving forward by half a step, it moves 1 out of the exchange area 39.
The row runs out, and one row can be crossed to add a new egg.

Execute the above calculation steps to extract the exchange program.

The above program operates as shown in FIG. That is, when one of the ten consecutive egg weights within a predetermined range is registered as an exchange egg as a result of the calculation of the exchange program, the control device 5 registers the egg weight within the exchange area as an exchange egg. The replenishment arm device 41 is operated and the position of the replacement egg is designated by Zarin. Then, the arm 43 of the replenishment arm device 41 is moved and the replacement eggs are taken out by the suction cup 44. In addition, the discharge arm device 42 moves the eggs marked as discharged eggs among the eggs accommodated in the container 37 to the discharge arm device 41. The replacement eggs are positioned by the arm 43 of the device 42, sucked and taken out by the suction cup 44, and the replacement eggs sucked by the suction cup 44 of the replenishment arm device 41 are stored in the empty storage seat of the container 37.

By the way, in this embodiment, the eggs that are sequentially transported are put into the container 38 on the standby line 14 and used as replacement eggs, but the eggs that are sequentially transported and are removed from the mixed packaging are grade-packed. Alternatively, replacement eggs may be placed in the container 38 on the standby line 14 so that replacement eggs can be selected and the weight of the eggs varies.

"LIL" - As another embodiment, only the replenishment arm device 41 is operated;
There is an egg sorting and packaging device that satisfies a set weight or a set weight range by replenishing eggs.

That is, in the progelanoum of the embodiment disclosed in Japanese Patent Application No. 61-47777, in order to obtain a set weight or a set weight range, calculations for combinations are performed in advance of 11 eggs, and the egg weight is selected. However, this is 1
If you go back one or more eggs to select the weight, for example, 30 eggs in advance, the eggs may have already been stored in one of the packaging lines or have already passed the combination line. Met. However, by providing the replenishment arm device 41, it has become possible to select the weight of 30 eggs first. 9th
As shown in the plan view showing the outline of this embodiment, the container 37 is placed in a container 37 placed on the mixing packaging line 13, and is housed in an open state. The programs executed at this time are the programs shown in FIGS. 10-a and 10-b that select up to 30 methods from the 11 methods. As a result of running this program, container 3
The eggs to be stored in the empty storage seat No. 7 are already stored in the container 38 on the waiting line 14, and the replenishment arm device 41 replaces the eggs that have been determined as mixed packaged eggs that have already been placed in the container 38. In this embodiment, only the replenishment arm device 41 is operated,
Control of the replenishment arm device 41 is performed in the same manner as in the first embodiment. In this case, as in the first embodiment, three exchange areas are provided on the standby line 14, and the replenishment arm device 4
When taking out the eggs in step 1, the waiting line 14 carries them half a step forward, and the eggs are taken out from the side closest to the place that would protrude from the three exchange areas.

In this embodiment, after determining a predetermined number of eggs as mixed packaging eggs, the selection range of insufficient eggs for one packaging unit is newly calculated, and the replenishment arm device 41 is operated to replenish the eggs. This is an egg sorting and packaging device that attempts to satisfy a set weight or a set weight range.

To explain this embodiment based on the drawings, Fig. 11 is a plan view showing the outline of this embodiment, Fig. 12-a is a selection program of this embodiment, and Fig. 1211Z-b is an exchange program. As shown in Figure 6, the mixing packaging line 13
9 as a predetermined number in the container 37 placed on the
When it is determined based on the program shown in FIG. 12-a that the number of eggs to be accommodated is determined, the selection range of one egg to be replenished is calculated by the program shown in FIG. When the eggs stored in the containers 38 are searched within the three exchange areas and the exchange eggs are determined, an operation command is output from the control device 5 to the replenishment arm device 41, and based on this command, The empty storage seat of the container 37 is replenished by rotation, movement, suction, etc. of the arm 43 and suction cup 44 of the replenishment arm device 41 in the same manner as in the method disclosed in the first embodiment.

By the way, the programs shown in FIGS. 12-a and 12-b operate by almost the same steps as the programs 812I-a and 812I-a in the first embodiment and FIG. 8-8. That is, in step 123 in the selection program of FIG. 12-a, in the first embodiment, the calculation areas Ell to
It is determined whether the egg weight in E20 is 10, but in this example, the predetermined number is 9.
We are determining whether or not it is an individual. If the number is 9, proceed to the exchange program shown in FIG. 12-b.

These nine pieces are stored in a container 37 placed on the mixing packaging line 13.
These are mixed packaged eggs that are put into the market. Then, in order to calculate the selection range of the missing number of 1 egg for 10 eggs as one packaging unit, and determine the replacement egg, the weights of 9 eggs are totaled in step 125, and the missing type iF for the set weight M is calculated. do.

That is, n(1)+n(2)+...+n(9)=
Σn(i)M−Σn(i>=F (where i=1..,9) In step 126, the predetermined weight range of 52g to 7
t”I determines whether there is a deficient itF within less than 6g.
I! I? If 52≦F and 76 are not satisfied,
The furthest egg weight pushed out by the shift is marked as a grade egg, and the process returns to step 111.

When 52≦F (76) is satisfied, in step 128, the selection ranges 61 to G2 of replacement eggs are calculated from the set weight ranges a to b.

That is, b-Σn(i)=G1 a-Σn(i)=G2 In steps 129 and 132, the egg weight E(h
, h) are equal to the missing type iF, and whether there is E(t, h) that satisfies the interpretation range G1 to G2.

If there is, proceed to step 1130 and step 131, select one egg from among the eggs accommodated in the container 38 of the waiting line 14, and collect this egg with the replenishment arm device 41.
It is registered to be placed in the empty storage seat of the container 37 on the mixing packaging line 13.

From this point on, processing is performed in the same manner as the exchange program in the first embodiment.

(Effects of the Invention) As mentioned above: - a replenishment arm device provided for replenishing the container with eggs determined as one egg of the package and, if necessary, eggs contained in the container on the mixed packaging line; With the egg sorting and packaging apparatus of the present invention, which is equipped with a discharge arm device for taking out eggs, it is possible, for example, to replace eggs that have been accommodated in one packaging unit with new eggs, or to replenish eggs to make one packaging unit. This makes it possible to obtain mixed packaging that satisfies the set weight or set weight range in one packaging unit, and as a result, mix-packed eggs can be selected again from the eggs that were excluded from selection, and the eggs that were excluded from selection can be reselected. By reducing
To improve the production rate of mixed packaging, and to select mixed packaging eggs for replenishment from newly placed eggs,
It was possible to improve the production rate of mixed packaging.

That is, the BF double weight of ffl'B4 210-day-old eggs is within a predetermined range from 52 g to less than 76 g,
The number of eggs as one packaging unit is 10, and the set weight or set weight range is 600g and 595g to 6
