Description

Detailed Description of the Invention (Industrial Application Field) The present invention sequentially weighs eggs, temporarily puts the weighed eggs on hold for each weight category, and determines the number of eggs to be packaged based on the number of eggs on standby. This invention relates to a sorting and packaging device.

(Conventional technology) Chicken eggs are classified into six grades, SS, S-MS, M, L, and 2L, based on trade standards of the Ministry of Agriculture, Forestry and Fisheries, and most of the eggs are sold according to these grades. It is sold in. For this reason, the sorting and packaging equipment used in the egg industry packs each grade on its own packaging line, so it requires as many packaging machines for each grade.

However, as is generally known, there are variations in eggs, and some packaging lines are always in operation, while others are in operation only occasionally, and it would be wasteful to set up all the packaging lines at the same time. It was known that In response to this, in order to reduce the number of packaging lines and packaging equipment required by the number of grade types, each egg is housed in an individual transport container, and each grade is placed on standby in a standby device. A sorting and packaging device has been proposed that transfers each packaging unit on a packaging line and wraps it in a packaging device.

(Problems to be Solved by the Invention) The present invention was devised to improve the above-mentioned sorting and packaging device, and instead of being particular about the conventional grades, standby devices are provided for each of the more finely divided weight categories. Depending on the number of eggs on standby in this standby device, a pre-stored pattern is selected, and combinations exceeding grades or packaging of grade eggs are performed, and in addition, packaging of grade eggs and combination eggs is performed. In order to process eggs using the same packaging device, a display device is provided to clearly indicate whether the flock of chicken eggs currently being processed is a grade egg or a combination egg.

(Means for solving the separation point) Therefore, the present invention is a weighing system that weighs each egg that is sequentially conveyed, and outputs the weight of the weighed egg to a control unit as an egg weight signal to a weighing layer. The device is located between a supply conveyor for supplying chicken eggs and a conveying device for sequentially conveying eggs that are weighed one by one and stored one by one in a conveying container. A first detection device is provided at the beginning of the conveyance device to monitor the conveyance container being conveyed on the conveyance device, and outputs a first detection signal to the control unit. , and the driving means of the conveying device includes:
A rotation detection device is provided that outputs a position detection signal synchronized with the speed of the transport device to the control unit. Then, a waiting device for waiting the eggs housed in the transport container is provided in the required number of rows along the transport direction of the transport device for each predetermined weight category of egg weight, and When the conveyance container to be conveyed reaches a push-out position at the entrance of the standby device corresponding to the egg weight of the eggs stored in the container,
A push-out device is provided that receives a push-out signal output from a control section and pushes out the transport container to the standby device.

Further, the standby device is provided with a gate at the downstream end of the standby device for releasing the transport container, which is an entrance to the standby device, in response to an opening/closing command output from a control unit, and the control unit , a pattern corresponding to the number of eggs waiting in the standby device is selected from release patterns stored in a storage unit, and an opening/closing command according to the release pattern is output to the gate. Then, the gate operates according to the opening/closing command. Also, adjacent to the gate, a second
A detection device is provided, which detects the conveyance container being discharged from the standby device to the next packaging line, and
It functions to output to the control unit as a detection signal. Further, a packaging line is provided along each of the standby devices, and conveys the eggs discharged from the standby device and housed in the conveyance container to a subsequent packaging device where the eggs are housed in packaging containers and packaged. Then, in the vicinity of the packaging machine, until the eggs stored in the transport container on the packaging line are packaged in the packaging container by the packaging machine, the egg weight of each egg group and the classification of grade eggs or combination eggs are stored. A display device is provided to display the information. By the way, each of the above devices is controlled by a control section, and the control section receives the egg weight signal, the first detection signal, the position detection signal, and the second detection signal, and stores the eggs in the storage section. In addition to outputting a heavy signal, it also outputs a push-out command to the push-out device, an opening/closing command to the gate, and a display command to the display device. This is also achieved by configuring the sorting and packaging device in such a manner that the storage section stores the egg weights of the eggs that have been weighed sequentially and the discharge pattern for discharging the eggs that have been on standby in the standby device. It is something.

(Example) An embodiment of the present invention will be described based on the drawings.

Between a supply conveyor (not shown) that supplies eggs 1 in a single row or multiple rows and a transport conveyor 3 that is a transport device that transports transport containers 5 containing weighed eggs 1 to each standby device 2. A weighing device 4 is provided which weighs each egg 1 and outputs an egg weight signal a to the weighing layer sequentially to the control section 15 after weighing. There are two methods for weighing chicken eggs: first, weighing only the chicken eggs and then storing them in the transport container 5, and first weighing the empty transport container 5, then weighing the egg 1 containing it, and then weighing it. There are cases where the weight of each chicken egg is calculated by calculating the value, but in any case, it is publicly known, and the weighing method is not limited in this example. A conveyor 3 is provided following the weighing device 4, and the eggs 1 are accommodated in each conveyance container 5 and conveyed respectively. When being transported, a first phototube 6 as a first detection device is attached in order to ascertain whether the weight of each egg 1 matches the weight already weighed and stored in the storage unit 15. It detects the conveyance container 5 being conveyed, and outputs a first detection signal to the control section 14. Further, a rotation detection device 7 is attached to a motor 8 which is a driving means of the conveyor 3, and when the conveyor 3 starts to be driven, based on the rotation of the motor 8,
The rotation detection device 7 outputs a clock pulse signal C as a position signal to the control section 14.

The first detection signal outputted from the first phototube 6 is synchronized with the clock pulse signal C outputted from the rotation detection device 7, so that the weight of the detected chicken egg 1 should be pushed out at which position. The clock pulse signal C is counted along with the movement of the transport conveyor 3, that is, the transport of the transport container 5, and the position is always grasped by the Ill11 section 14. Then, standby devices 2 are provided in the direction perpendicular to the flow of the conveyor 3 in the number of weight categories finely divided by grade, and the standby devices 2 are provided in parallel on the same side of the conveyor 3. On the other side, the same number of extrusion devices 9 are provided across the conveyor 3, on the same line as the standby device 2, and facing the entrance of the standby device 2. 10 is pushed out by the pushing signal d from the control unit 14, the transport container 5 is pushed out without any force.

By the way, the extrusion device 9 is driven by a linear motor, and the pusher 10 is reciprocated.

A gate 11 is provided at the downstream end of the standby device 2, and a motor (not shown) is installed based on an opening/closing command C from a control unit 14.
The operation of the gate 11 rotates the gate 11 to open and close it. In addition, a second phototube 12 as a second detection device is attached to the other downstream end, and the phototube 12 monitors the standby device 2 so as to cross the standby device 2 at right angles to the traveling direction of the standby device 2. ing. Then, the number of times the transport container 5 is released from the standby device 2 is counted, and the second
The detection signal f is outputted to the control section 14. A packaging line 13 faces the downstream end of each standby device 2, and serves to transport the conveyed containers 5 as a group of packaging units and lead them to a packaging device (not shown).

The metering device 4, the first phototube 6, the extrusion device 9, the rotation detection device 7, the second phototube 12, and the gate 11 are controlled by the control unit 14.
A display device 16 is installed near the packaging device (not shown), and displays information in response to a display command 8 from the control section 14. In other words, the weight of eggs not weighed by the weighing device W4 is controlled by the control unit 14.

When the detection signal from the phototube 6 that detects the conveyance container 5 containing weighed eggs is detected, the control section always sends a clock pulse signal C from the rotation detection device W7 attached to the motor 8 which is the driving means of the conveyor 3. It has been sent on 14,
The first detection signal from the first phototube 6 causes the storage unit 1 to
When the eggs 1 are conveyed to the entrance of the standby device 2 where they are to be kept, the pushing device 9 facing the standby device 2
In order to push out the bushing 10, the conveyance distance up to that point is constantly calculated using the clock pulse signal C. When the pusher 10 of the extrusion device 9 operates, the conveyance containers 5 that have arrived there are sent to the standby device 2, and at the same time, the storage unit 15 updates the number of conveyance containers 5 waiting in the standby device 2. Therefore, 1 is added. The eggs 1 stored in the transport containers 5 waiting in each standby device 2 are stored in the storage unit 15 for the order of standby, the number of eggs 1, and the egg weight of each egg 1, and which It is possible to check at any time whether the standby device 2 is in a saturated state or is becoming saturated. In other words, a standby device that satisfies this by setting the number of eggs on standby! The pattern of the selected standby device 2 is compared with the pattern previously stored in the storage unit 15, and the matched emission pattern is notified to the control unit 14, and the control unit 14 An opening command e is issued to each gate 11. 1. When the transport container 5 is released from each standby device 2 based on a matched pattern.

A second phototube 12 counts the number of emitted particles.

The number of pieces to be released is monitored at the same time as the waiting number stored in the storage unit 15 is subtracted, and when a predetermined number of pieces are released, the gate 11 is closed. Furthermore, the control unit 14 displays on the display device 16 the weight of each egg 1 in the order of conveyance, and at the same time, if the egg group is a grade egg, the size thereof is displayed, If it is a combination egg, the total weight is displayed. 0 The weight of each individual egg is displayed when the egg 1 is broken during sorting and transportation after breeding, and it is picked out on the packaging line 13 or on the packaging machine. In this case, it is possible to know how many grams of eggs 1, that is, which waiting device 2 should be replenished with eggs 1.

The specific operation of the sorting and packaging apparatus of this embodiment configured as described above will be described below. First, the weight of the weighed eggs 1 is sequentially stored in the storage unit 15 as an egg weight signal a, and the transport container 5 containing the weighed eggs 1 placed on the transport conveyor 3 is transported in the direction of arrow E. be done. At that time, the transfer container 5 is detected by the first phototube 6 and outputs the first detection signal C, and at the same time, in synchronization with the clock pulse signal C output from the rotation detection device 7, the transfer container 5 is to store in the storage unit 15 whether the computer should be put on standby;
When the transport container 5 reaches the extrusion position of the extrusion device 9 facing the standby device 2, the extrusion command d is output from the control section 14 to the corresponding extrusion device 9. The control unit 14 always calculates and controls when the extrusion position is reached based on the number of clock pulses stored in the storage unit 15, such as how many pulses are needed to determine which position. When the push-out command d is output from the control unit 14, the pusher 10 of the push-out device 9 is activated to push out the transport container 5 to the stand-by device 2. The number of eggs 1 waiting in the waiting device 2 is added by the number of pushing operations of the pushing device t9, and is stored in the storage unit 15 for each waiting device 2 along with the weight of the waiting eggs.

(Less than 64g), (C) (56 to less than 58g), (E) (
60 to less than 62 g) and ()) (64 to less than 66 g) are selected, and a pattern that matches this pattern is searched from among the release patterns stored in the storage unit 15, and the release pattern of the pattern is selected. According to the number of pieces, in this case, 3 pieces of 59.1g, 59.2g, and 59.0g from (d), 3 pieces of 62.5g, 626g, and 62.7g from (f), and 57.4g from (c), 2 pieces of 56゜9g, 1 piece of 61.5g from (E), 1g of 65.7H from (G)
is released. That is, the control unit 14 outputs an opening/closing command e according to the pattern to each target gate 11. At this time, the gates 11 are opened in order from the gate 11 in the transport direction D of the packaging line 13. By the way, the standby device 2 is a belt conveyor, and the stocked transport containers 5 are transported in the direction of arrow B. Gate 11
The packaging line 13 is also made of a belt conveyor and conveys the containers 5 in the direction of the arrow. When the transport containers 5 corresponding to the stored patterns are released, the gates 11 are respectively closed.

The released eggs 1 in the transport container 5 are transported to a packaging device by a packaging line 13. At this time, a display command g is output from the control unit 14 to the display device 16, and the eggs 1 are conveyed in the order of 65.7 g, 62.5 g, 62°6 g, 62.7 g, 6
1.5g, 59.1g, 59°2g, 59.0+r, 5
