As shown in fig. 2 and 3, in one embodiment, a one-way box pushing mechanism 13 is used as the pushing mechanism. The overlook visual angle is the structure that the quasi-circulation cooling bin body 12 extends to be the rectangle, the four sides of the circulation cooling bin body 12 are all provided with one-way box pushing mechanisms 13, the extending direction of each one-way box pushing mechanism 13 is all parallel to the side of the circulation cooling bin body 12 where the box pushing mechanisms are located, and the pushing directions of the four one-way box pushing mechanisms 13 are sequentially combined to be the clockwise conveying direction so as to drive the fish basket 14 to move clockwise in the circulation cooling bin body 12.

As shown in fig. 4, the unidirectional box pushing mechanism 13 includes a cabin top support 13d installed on the outer wall of the circulating cooling cabin body 12, and a linear driving assembly 13a installed on the cabin top support 13d, a telescopic rod 13b is connected to the cabin top support 13d in a sliding manner, one end of the telescopic rod 13b is connected to the output end of the linear driving assembly 13a, a box pushing block 13c is sleeved on the telescopic rod 13b, and the box pushing block 13c extends into the inner cavity of the circulating cooling cabin body 12 and is used for horizontally pushing the fish basket 14 in the circulating cooling cabin body 12.

The first lifting mechanism 2, the first lateral movement conveying belt 4, the second lateral movement conveying belt 7, the second lifting mechanism 10 and the pushing mechanism of the circulating cooling bin body 12 are electrically connected with the controller and act under the control of the controller.

As shown in fig. 1 and 6, a camera 8 with a shooting direction facing to the upper surface of the transfer conveyor 6 is arranged above the transfer conveyor 6, and an RFID card reader 5 is arranged on the warehousing frame 1 higher than the second side-shifting conveyor belt 7; the camera 8 and the RFID reader 5 are both connected to a controller, which is configured to:

shooting the fish basket 14 on the transfer conveyor 6 according to the camera 8, and identifying the type and specification of the fish in the fish basket 14 according to the shot picture (a conventional image identification method can be adopted); reading the RFID electronic tags 15 of the fish baskets 14 after the fish baskets 14 are moved from the transfer conveyor 6 to the second side-shifting conveyor belt 7, and binding the information of the RFID electronic tags 15 with the identified types and specifications;

the minimum residence time of the fish basket 14 in the circulating cooling bin body 12 is determined according to the type and specification of fish in the fish basket 14, and the residence time of the fish basket 14 in the circulating cooling bin body 12 is adjusted by controlling the pushing speed of the pushing mechanism. The cooling time varies among different species of fish of different sizes, and the larger the fish, the longer the cooling time is required so that the inside of the fish is also rapidly cooled to a target temperature, and the viscera of the fish contain a large amount of microorganisms, which if cooled slowly, cause the proliferation of the microorganisms.

After the fish basket 14 moves for one circle in the circulating cooling bin 12 and the minimum residence time is met, the second lifting mechanism 10 is controlled to lift the fish basket 14, so that the fish basket 14 leaves the circulating cooling bin 12, the position of the fish basket 14 is continuously detected after the fish basket 14 leaves the circulating cooling bin, and the control system performs further actions after the fish basket 14 is moved to the circulating support table 16 by a carrying person.

The fish in each basket 14 are of different sizes, with some baskets being significantly larger than others. In this case, if a certain fish basket 14 moves one turn in the circulating cooling bin 12 and the staying time in the circulating cooling bin 12 does not satisfy the minimum staying time of the fish basket 14, the controller controls the pushing mechanism to push the fish basket 14 to move one turn, jump over the fish basket 14 and take out other fish baskets 14.

To accomplish this, the controller needs to know the position of each basket 14 in the recirculating cooling cartridge 12. In this embodiment, the internal cross-sectional shape of the circulating cooling bin 12 is matched with the fish baskets 14, and the fish baskets 14 are arranged in the circulating cooling bin 12 in sequence; the controller judges the position of each fish basket 14 in the circulating cooling bin body 12 according to the internal shape of the circulating cooling bin body 12, the size of the fish basket 14 and the pushing distance of the pushing mechanism.

In this embodiment, the controller may be implemented by using an industrial personal computer having a GPU. The fish can be rapidly frozen to a preset temperature through the circulating cooling bin body 12 so as to be preserved at a low temperature later.

As shown in fig. 1, 2 and 5, the warehousing component and the transfer component are both located at the inner side of the circulating cooling cabin 12, and the circulation support platform 16 is located at the outer side of the circulating cooling cabin 12 and extends outward.

As shown in fig. 1 to 6, the working process of the system of the present embodiment includes the following steps:

(1) the warehousing part lifts the fish frame 14 with the catches to the height which is flush with the transfer conveying frame 6; in the process, the controller reads the RFID tag of the fish basket 14 through the RFID card reader 5 to obtain the serial number of the fish basket 14;

(2) the first side moving conveyor belt 4 moves the fish basket 14 with the fish catches to the transfer conveyor frame 6, meanwhile, the controller shoots pictures of the fish in the fish basket 14 through the camera 8, identifies the types and the specifications of the fish, and binds the types and the specifications with the serial number of the fish basket 14; the recognition algorithm of the image can be secondarily developed on the basis of open source frameworks such as Yolo v3 and the like;

(3) the second sidetrack conveyor 7 of the transfer conveyor 6 transports the fish basket 14 to the second lift seat 11; then the second lifting seat 11 sinks down and sinks into the circulating cooling bin body 12;

(4) the pushing mechanism pushes the fish basket 14 in the cooling bin body 12 to move; after the next cooled fish basket 14 in the cooling bin 12 is pushed onto the second lifting seat 11, lifting the second lifting seat 11 to lift the fish basket 14 to a height level with the transfer conveyor 6; the carrier drags the fish basket 14 to the transfer conveyor 6 and then carries it away. In this embodiment, the last link is controlled by the carrier, and only after the lifted fish basket 14 is carried away, the controller controls the system to perform subsequent operations, so that the problem that the existing automatic production line carrier needs to work strictly according to the rhythm of the machine can be avoided, and the marine bumpy environment can be effectively adapted.

While the preferred embodiments of the present invention have been described, those skilled in the art will appreciate that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
