[0002]

2. Description of the Related Art In an automatic sorting and packaging apparatus for eggs such as hen's eggs, generally, eggs are loaded on a conveyor and conveyed while being subjected to predetermined processes such as egg washing, drying, egg inspection, weighing, and the like. Is stored in a packaging container and shipped. The weighed eggs are usually transported in a single row on a single-row conveyor (first conveyor), and stored in a packaging container that is transported by a container conveyor arranged orthogonal to the single-row conveyor. A plurality of container conveyors (this constitutes a sorting station in the prior art) are provided. Eggs selected based on the weight value of the eggs measured by the weighing device are used to select one of the eggs based on the sorting result. Packaged at the station.

[0003] The problems in the prior art as described above are as follows.
This is the case where the packaging containers conveyed by the container conveyor are exchanged. There are various types of packaging containers according to the demands of the shipping destination.
There are as many as 36, and there are various types of packaging containers having the same number but different shapes. In order to replace the packaging container with another one, it is necessary to stop the container conveyor, so it is necessary to stop the single-row conveyor, etc. Therefore, the entire egg processing equipment must be stopped, and the entire equipment operates Efficiency was low to reduce the rate.

[0004] As a prior art which has solved the above problems, there is a chicken egg sorting and packaging apparatus (hereinafter referred to as prior art) disclosed in Japanese Patent Application Laid-Open No. 8-11826. This is a container
(Corresponding to the second conveyor of the present application) is provided for conveying the loaded (corresponding to the filling container of the present application) state. In this way, instead of directly discharging the eggs from the single-row conveyor to the packaging container, the eggs are once delivered to the filling container, and the egg is transferred from the storage container to the packaging container by the transfer device. A plurality of transfer devices are provided in a state orthogonal to the single-row conveyor, and constitute a sorting station.

[0005]

In the above prior art, when a predetermined number (ten) of containers containing eggs are collected in the transport device, the transfer device is operated to transfer the eggs from the container to the packaging container. It is designed to be relocated.

However, if the operation timing of the transfer device is set as described above, the following problems occur. Even after a predetermined number of containers are collected in each transport device, some containers can be charged (stored), and the number of containers that can be charged depends on the position at which the eggs are released into the containers and the number of eggs. It is determined by the distance relationship with the position taken out by the transfer device, and the number of charges in the storage container naturally has an upper limit. Therefore, when transferring eggs, it is necessary to check the number of charges in the storage container, and if only a predetermined number of storage containers are checked as in the prior art, the transfer device However, the charge function of the hen cannot be sufficiently exhibited, and the efficiency of the egg transfer operation cannot be said to be high.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an automatic egg sorting and packaging apparatus for effectively exerting a charge function of a transport device (second conveyor) and improving the efficiency of egg transfer. .

[0008]

To achieve the above object, an automatic egg sorting and packaging apparatus according to the present invention comprises: a weighing device for measuring a weight value of a conveyed egg; A controller for sorting eggs, a first conveyor for transporting the weighed eggs, a filling container for storing the eggs discharged from the first conveyor, and a large number of the filling containers along the circulation path. A second conveyor that is driven in circulation, and an egg transfer unit that takes out the eggs stored in the filling container and transfers the eggs to a container conveyor on which a packaging container in which the eggs are packaged is transported. The circulation path in the two-conveyor is provided with a take-out area where the eggs can be taken out by the egg transfer means, and a storage area located on the upstream side of the take-out area, and the charging area stored in the storage area is provided. Is characterized in that based on the number of the container by actuating the egg transfer unit performs sorting eggs.

The control device sorts eggs based on the measured weight value. For example, if sorting based on agriculture and forestry standards is performed, M class (58.0-63.9 g), L class (6
4.0 to 69.9 g). When the weighing by the weighing device is completed, the eggs are conveyed on the first conveyor, for example, in a single row. Next, the eggs are released from a predetermined location on the first conveyor based on the sorting result, and are once conveyed on the second conveyor before being packaged in a packaging container. The position discharged from the first conveyor is
It is determined based on the result of the selection.

The reason why the eggs are not directly discharged from the first conveyor to the packaging container of the container conveyor but the second conveyor is interposed is as follows. That is, the container conveyor must be stopped when the packaging container is changed on the container conveyor or when trouble occurs on the container conveyor. At this time, eggs are being conveyed one after another to the first conveyor, but if the configuration is such that the eggs are directly discharged from the first conveyor to the packaging container, if the container conveyor is stopped, automatic sorting including the first conveyor is performed. The entire packaging device must be stopped, which greatly reduces the efficiency of the packaging operation. However, if a configuration in which the eggs are discharged from the first conveyor to the second conveyor is adopted, the eggs discharged from the first conveyor can be stored (charged) in the second conveyor, so that the container conveyor must be stopped. Even if a necessary situation arises, it is not necessary to stop other device parts such as the first conveyor, so that the work efficiency does not need to be reduced.

The egg transfer means is operated to transfer eggs based on the number of the filling containers stored in the storage area. For example, the largest number of fillings are stored in the storage area. It is possible to perform control such that eggs are transferred to the one in which a container exists. As a result, the storage space in the storage area of the second conveyor can be reliably ensured, and the charging function of the second conveyor can be effectively exhibited to improve the efficiency of egg transfer work.

According to this configuration, the filling container is charged starting from the first stopper, and when a predetermined number is charged, the second stopper prevents the further filling container from entering the take-out area. can do. After taking out the egg from the filling container in the take-out area, the first stopper is released and the empty filling container is sent out, and the second stopper is also released, and the filling container in the storage area is sent into the take-out area. . By separating the take-out area and the storage area by the first stopper and the second stopper, the number of filling containers in each area can be reliably grasped.

As another preferred embodiment of the present invention, a plurality of the second conveyors are provided, and the container conveyor includes a first container conveyor capable of transporting a first packaging container and a second packaging container. A first storage unit that stores at least two transportable second container conveyors, and further stores processing data of the second conveyor that can transfer eggs to the first container conveyor; and the second container conveyor. And a second storage unit for storing processing data of the second conveyor capable of transferring eggs to the second conveyor.

Here, the processing data includes data relating to the number of filled containers stored in the storage area. By providing the first storage unit for the first container conveyor and the second storage unit for the second container conveyor separately as in the above configuration, it is possible to efficiently operate the plurality of container conveyors while checking the operation status. Egg transfer processing can be performed.

For example, the first container conveyor and the second container conveyor
A determination means for determining whether or not the operation of the container conveyor is possible is provided, and the operation of the egg transfer means is performed based on the determination result of the determination means. If the first container conveyor is stopped due to a trouble or the like, the transfer and packaging of the eggs can be performed with priority given to the second container conveyor. I was able to plan.

Further, when it is determined by the determining means that both the first container conveyor and the second container conveyor can be operated, the most filled containers are stored in the storage area. It is preferable to perform the transfer of the eggs of the second conveyor described above.

As described above, by transferring eggs from a large number of filling containers charged in the storage area, a storage space in the storage area of the second conveyor can be reliably secured. The charging function of the two conveyors can be effectively exhibited.

Another automatic egg sorting and packaging apparatus according to the present invention comprises: a weighing apparatus for measuring a weight value of a transported egg;
A control device for sorting eggs based on the measured weight value,

And the container conveyor, a first container conveyor capable of transporting a first packaging container,
It is provided with at least two second container conveyors capable of transporting the second packaging container, and is provided with a judging means for judging whether or not the first container conveyor and the second container conveyor can be operated. The operation of the egg transfer means is performed based on the determination result of the means.

By providing such a judging means,
For example, if it is determined that the first container conveyor is stopped due to a trouble or the like, the transfer and packaging of eggs can be performed with priority given to the second container conveyor.

If the judging means judges that both the first container conveyor and the second container conveyor are operable, the largest number of the filled containers are stored in the storage area. It can also be said that the transfer of the eggs of the second conveyor is performed. in this way,
By performing transfer of eggs from a large number of filling containers charged in the storage area, a storage space in the storage area of the second conveyor can be reliably secured,

<Structure of Storage Unit> Next, the structure of the storage unit is shown in FIG.
3 is shown. FIG. 14 is a schematic diagram of an automatic egg sorting and packaging apparatus corresponding to the contents stored in the storage unit. In FIG. 14, the first station (1s
t) to the sixth station (6st) are shown, of which the first station (1st) to the third station (3st) are used for sorting and packing into packs 60, and the fourth station (4st) to the sixth station (6st). It is assumed that the station (6st) is set as sorting / packing on the tray 61. As the packaging station 6, two pack conveyors 62 and a tray conveyor 63 are set. In FIG. 14, the charger 21 is indicated by a thick horizontal line for simplification of the drawing.

FIG. 13A shows the storage contents of the storage area count data in the state shown in FIG. Here, the number of chargers 21 charged in the storage area R2 is stored. For example, the number is 5 for 3st and 4 for 5st.

FIGS. 13B and 13C show a pack FIFO buffer (first storage unit) and a tray FIFO buffer, respectively.
Indicates a buffer (second storage unit), for example, a pack FI
The FO buffer stores 3rd processing data and 1st processing data. The arrangement of the data is in the order of increasing number of charges, and for the 2st, there is no charger 21 in the storage area R2 yet, so that there is no data in the buffer.

<Description of Operation of Automatic Sorting and Packaging Apparatus> Next, the operation of the automatic sorting and packaging apparatus for eggs according to the present embodiment will be described step by step. FIG. 15 shows an outline of the processing steps of the egg 1. First, the eggs 1 introduced from the chicken house or the like are transported in a state of six rows, and are washed and dried. Next, after performing directional alignment (orientation) for aligning the directions of the blunt end portion and the sharp end portion of the chicken egg 1, the automatic inspection device 10 performs egg inspection. Then, after weighing the egg 1 with the weighing device 11,
Transfer 6 to single row conveyor 14 by transfer device 17
Change from one row to one row. The eggs 1 transported by the single-row conveyor 14 are discharged to the charger 21 based on the sorting result. Then, the chicken eggs 1 stored in the charger 21 are transferred and packaged in a packaging container by the chicken egg adsorption device 70, and a series of processing is completed.

FIG. 16 is a flowchart for explaining the sorting operation. First, chicken egg 1 is weighed (# 1
0), the chicken egg 1 determined to be a defective egg by the automatic inspection device 10 is selected as a defective egg without performing normal sorting (# 11, # 12), and collected at the defective egg collection station 4. You. Also in this case, the number of pulses up to the defective egg collection station 4 is set in the same manner as in the case of a normal egg described later.

The non-defective eggs 1 are sorted as normal eggs (# 12), but are first sorted using the weight range table of rank 1 (# 13). 8 to 10
According to the example of the sorting station NO. 6 is “2-M”. Since this is 57.0 to 63.9 g according to FIG.
If the weight value of chicken egg 1 is in this range, it is sorted. If it is not in this range, sorting is performed using the rank 2 weight range table (# 14). As shown in FIG. 5 “4-L” and station No. 7, these ranges are from 63.0 to 70.9 g for “4-L” from FIG.
-M "is 58.0 to 63.9 g, and if it falls in any of these ranges, it is sorted. Then, in the case where the sorting is also out of the sorting by the rank 2, the sorting by the lowest rank is performed (# 15). This means that the sorting is performed at the station in which the column of "rank" is blank in FIG.

By the sorting of the eggs 1, the sorting station 5 to which the eggs 1 are to be transported is determined, and the number of pulses corresponding to the distance to the discharge position where the eggs 1 are discharged to the charger 21 of the filling conveyor 20 constituting the sorting station 5 Is set in the memory in the control device 7 (# 16). Chicken egg 1
When the pulse is conveyed in a single row by the single-row conveyor 14 (# 17), the set pulse number is subtracted and counted every time a pulse signal is generated from the encoder 16 linked to the single-row conveyor 14, and the time when the pulse number becomes 0 The kick device 18 is operated to release the eggs 1 (# 18, # 19).

<Description of Operation of Filling Conveyor> Next, the operation of the filling conveyor 20 in the sorting station 5 will be described with reference to FIG.
7 will be described with reference to FIGS. The release of the eggs 1 from the single-row conveyor 14 to the charger 21 is performed one by one by the kick device 18. When six eggs 1 are released to the charger 21 in one horizontal row (# 3
0), the third cylinder 44 is operated to release the third stopper 43 (# 31). As a result, the restraint of the charger 21 in which the eggs 1 are stored is released, and the eggs 1 are transported by the endless chain 30 in the direction of arrow D. By the third sensor 45,
When it is detected that only one charger 21 has passed (# 32), the third cylinder 44 is operated again, the third stopper 43 is inserted on the transport path, and the next charger 2
1 is positioned at the receiving position P2 (# 33).

The discharged charger 21 is charged in the take-out area R1 in order from the charge head position P1 if the second stopper 46 is not inserted. When the second stopper 46 is in the inserted state, the storage area R2 is charged in order. The control device 7 detects the number of actuations of the third cylinder 44 or the number of chargers 21 that have passed through the second sensor 48,
Charger 21 charged in take-out area R1
When the number becomes 10 (this number varies depending on the packaging pattern) (# 34), the chicken egg suction device 70 is operated to charge the charger 2 to the suction unit 70a.
And take out the egg 1 stored in the container 1 by vacuum suction (#
35).

When the removal of the eggs 1 is completed, the first cylinder 41 is operated to retract the first stopper 40 from the transport path and release it (# 36). As a result, the empty charger 21 is transported by the endless chain 30 again. When the first sensor 42 detects that ten chargers 21 have passed (# 37), the first cylinder 41 is operated again to insert the first stopper 40 on the transport path (# 38). At this time, if the second stopper 46 is in the inserted state, it is released, and the intrusion of the charger 21 into the take-out area R1 is permitted. Thus, charging of the charger 21 is started again. As described above, since the charger 21 can be charged, even if it is necessary to stop the pack conveyor 62 or the tray conveyor 63, it is not necessary to stop other parts, and the sorting operation is continued. Can be performed without lowering work efficiency.

When the empty charger 21 moves from the upper transport path to the lower transport path, the first guide groove M1
Guided by In the upper transport path, the charger 21
Roller 30a of the endless chain 30
However, when the charger 21 passes through the first guide groove M1, the endless chain 30
Is cut off. As shown in FIG. 2, the first guide groove M1
And the endless chain 30 intersect on the way,
As shown in FIG. 2, the width of the pair of endless chains 30 is widened so that they do not interfere with the charger 21. Note that the charger 21 slides down the first guide groove M1 by its own weight and descends, so that a special power source is not required. When the charger 21 slides down the first guide groove M1, the width of the pair of endless chains 30 returns to the original, and the lower end of the charger 21 in the lower conveyance path.
The upper contact surface 21d of the roller 30a of the endless chain 30
It is conveyed while being mounted on. Therefore, the charger 21 is in the upside down state in the lower transport path but does not fall. When sliding down, the engaging portion 21b of the charger 21 is guided while being held in the first guide groove M1.

After passing the end of the lower transport path, the second
It is lifted to the upper conveyance path along the guide groove M2. At the end of the lower transport path, the charger 21 is engaged by the engagement lever 35 (an engagement mechanism is omitted).
By rotating the third guide body 34a counterclockwise in FIG. 2, the charger 21 is forcibly lifted along the second guide groove M2. Also in this case, since the width of the endless chain 30 is widened, the endless chain 30 does not interfere with the charger 21 even though the endless chain 30 and the second guide groove M2 intersect. . When the charger 21 is lifted along the second guide groove M2, the engagement lever 35 automatically releases the engagement state with the charger 21 by its own weight, and the lower contact surface 21c of the charger 21 is again moved to the endless chain 30. Is brought into contact with the roller 30a.

<Description of Packaging Operation> Next, the operation relating to the packaging operation of the eggs 1 will be described with reference to the flowcharts of FIGS. FIG. 19 shows the case of packaging in a pack 60, but the same applies to the case of packaging in a tray 61. In FIG. 18, the judgment means 97 of the control device 7 is
It is checked whether or not the operation of 0 is possible (# 5)
0). If the operation is possible, it is checked whether or not there is data to be processed in the pack FIFO buffer or the tray FIFO buffer (# 51). If there is data only in the pack FIFO buffer, the first processing data (3st processing data in the example of FIG. 13A) at the beginning is read out (# 54). Egg suction device 7 based on this data
0 starts the operation (# 56), and when the operation is completed (# 5)
7) Return to step # 51.

In step # 51, the tray FIF
If there is data only in the O-buffer, the one-time data at the beginning is read out (# 55), and the process proceeds to step # 56 and subsequent steps. If it is determined in step # 51 that there is data in both the tray FIFO buffer and the pack FIFO buffer, then the pack line (packing station constituted by the pack conveyor 62) and the tray line (tray (A packaging station including the conveyor 63) is operable or not (# 5).
2). If only the pack line is operable, the process proceeds to step # 54. If only the tray line is operable, the process proceeds to step # 55. In this way, even if one of the lines is inoperable, the packaging operation can be performed on the other line, so that the efficiency of the packaging operation does not decrease.

If it is determined in step # 52 that both the pack line and the tray line are in a operable state, the process proceeds to step # 53 to determine which station the maximum value of the storage area count data is. , And the station determines whether it is for a pack or a tray. For example, in the example shown in FIG. 13A, the maximum value is obtained for the 3rd pack sorting station. In step # 53, if it is determined that it is for a pack, the process proceeds to step # 54, and if it is determined that it is for a tray, the process proceeds to step # 55. If there are a plurality of stations having the maximum value, the setting is made so that the smaller the station number, the higher the priority.

Next, the flowchart of FIG. 19 will be described. The chicken egg suction device 70 in a state where the chicken egg 1 is sucked is moved along the guide rail 71 and is moved to the packing conveyor 62 where the sucked chicken egg 1 is to be packed. 6 × 10 = 60 chicken eggs 1 are sucked. on the other hand,
Since the packs 60 are packed with 6 × 2 = 12 pieces, five packs can be packed at a time. Conveyor for pack 62
The packs 60 are conveyed side by side at predetermined intervals.
The interval between the zero suction portions 70a can also be changed by a pantograph mechanism (not shown) (description of the mechanism is omitted). In this way, the chicken egg 1
To complete the packaging (# 40).

Next, the suction cylinder 66 is operated (# 4).
1) Supply only one pack 60 stored in the storage chamber 64a of the pack supply device 64 onto the pack conveyor 62 (# 42). Then, the pack conveyor 62 is driven to convey the pack 60 by a predetermined distance (# 43). By supplying five packs 60, preparation for the next packaging operation is completed (# 44).

Next, the operation at the time of switching the packaging container will be briefly described. For example, in the case of switching from the first pack 60 to the second pack 600 in the pack supply device 64, first, when the planned number of packaged products to be produced by the first pack 60 is produced, the control device 7 sends the product to the suction cylinder 67. Then, a command is issued to supply the second pack 600 to the pack conveyor 62. As described above, since the pack conveyor 62 does not need to be stopped when switching the packaging containers, the efficiency of the sorting operation does not decrease even if the setting is changed.

Since the weighing device 11 for the egg 1 and the packaging station 6 are located at a distance from each other, a signal from the control device 7 to replace the packaging container is sent from the controller 7 to the weighing device 1.
This signal is output when the sheet is conveyed to a predetermined position after passing through No. 1.

<Another Embodiment> Next, some other embodiments will be described. In the present embodiment, chicken eggs are sorted, but eggs other than chicken eggs can be sorted. In the present embodiment, the eggs 1 are transported in six rows by the egg feeding conveyor 12, but two egg feeding conveyors 12 are provided to
The conveyors may be transported in two rows, and two or more single-row conveyors 14 may be provided correspondingly.

As the sorting station, a station for constant weight packing can be provided. Here, the fixed weight packing is a packaging method performed by designating the number of packages and the total weight, and refers to a method of irrespective of the weight value of each individual egg. As the control device 7 of the present embodiment, one that controls the entire automatic sorting and packaging device for eggs is shown, but a control portion that controls the operation of the station portion and a control portion that performs other controls are included. You may comprise separately. It is preferable that the size of the take-out region R1 and the storage region R2 be made variable by changing the position of the second stopper 46.
