The working principle of this embodiment is as follows:
When refrigerated products are put in storage, the refrigerated products are placed in the material barrels 3, then the material barrels 3 with the refrigerated products placed are placed on the forks 4-1 of the self-running trolley 4, the material barrels 3 with the refrigerated products placed are conveyed to the turntables 2-1 in the refrigeration house 1 by the self-running trolley 4, then the lifting assembly drives the forks 4-1 to descend, the material barrels 3 on the turntables 2-1 are placed on the turntables 2-1, each material barrel 3 is input on the turntables 2-1, and the turntables 2-1 rotate by a certain angle, so that the positions of different refrigerated products on the turntables 2-1 can be conveniently and rapidly found; when refrigerated products are taken out of the refrigerator, the refrigerated products to be taken out of the refrigerator are selected, the power assembly drives the rotary table 2-1 to rotate so as to enable the storage barrel 3 where the refrigerated products to be taken out of the refrigerator are located to be close to the guide rail 5, then the storage barrel 3 is moved to the position of the storage barrel 3 by the self-running trolley 4, meanwhile, the fork 4-1 of the self-running trolley 4 is located at the bottom of the storage barrel 3, then the lifting assembly drives the fork 4-1 to lift so as to separate the storage barrel 3 on the storage barrel from the rotary table 2-1, and then the storage barrel 3 is transferred to the outside of the refrigerator 1 by the self-running trolley 4.
Although the above design can realize automatic entry and exit of refrigerated products into and from the refrigeration house 1, the space utilization rate of the refrigeration house 1 is not ideal, and the specific analysis is as follows:
As a general knowledge in the art, the first choice of the bucket 3 is generally circular, when the circular bucket 3 is placed on the turntable 2-1 together, as shown in fig. 10, a larger gap exists between two adjacent buckets, which results in lower space utilization rate of the refrigerator 1, and in order to more firmly clamp the bucket 3 when clamping the bucket 3, a person skilled in the art may think that the bucket 3 is arranged in a hexagonal shape, but the bucket 3 is designed to be far insufficient, under the concept that the shortest stroke of the bucket 3 in and out of the refrigerator 1 is needed by the self-running trolley 4, the position of the guide rail 5 is generally designed to be parallel to the running direction of the self-running trolley 4, so that the shortest stroke of the self-running trolley 4 in and out of the refrigerator 1 is realized, and the two clamping arms 6-1 on the two clamping arms are also necessarily clamped on two outer sides of the bucket 3, which are symmetrical to each other, so that the bucket 3 on the fork 4-1 is also necessarily provided with two outer sides and the bucket 3 are also necessarily opposite to each other, namely, the two adjacent buckets 2-1 are also opposite to each other, which is also seen in a relatively large gap is formed between the two adjacent buckets 2-1 and the turntable 2-1, which is also is opposite to the situation that the two adjacent buckets 2 are not necessarily shown in the opposite directions of moving the two adjacent buckets 2-1, as shown in the aspect.
Example 2
Example 2 differs from example 1 in that: as shown in fig. 1 and 3, the cross section of the charging basket 3 is hexagonal, the upper surface of the rotating disc 2-1 is divided into six storage areas 2-11 for placing the charging basket 3 at equal intervals along the circumferential direction, one end of the guide rail 5, which is positioned in the cold storage 1, is provided with a storage station, when the self-running trolley 4 reaches the storage station along the guide rail 5, the fork 4-1 on the self-running trolley 4 is positioned in one storage area 2-11, which is closest to the inlet and outlet of the cold storage 1, on the rotating disc 2-1, the position of the guide rail 5 relative to the rotating disc 2-1 is set so that the innermost outer side surface of the charging basket 3 on the self-running trolley 4 faces the center of the rotating disc 2-1 when the self-running trolley 4 moves to the storage station, and the hexagonal charging basket 6 can facilitate the clamping of the manipulator 6.
As shown in fig. 3, each storage area 2-11 on the turntable 2-1 is provided with a cushion block 2-12 for placing the charging bucket 3, and the charging bucket 3 on the turntable 2-1 is lifted by adopting the cushion block 2-12, so that a certain gap is formed between the bottom of the charging bucket 3 and the turntable 2-1, and a pallet fork 4-1 on the self-running trolley 4 when the self-running trolley approaches the turntable 2-1 can be inserted into the bottom of the charging bucket 3 from the gap.
The inlet and outlet of the refrigeration house 1 are eccentrically arranged relative to the rotary disc 2-1, and the guide rail 5 extends along the linear direction.
Preferably, the cross section of the barrel 3 is regular hexagonal.
In the embodiment, the storage barrels 3 stored with the refrigerated products are conveyed to the storage stations in the refrigeration house 1 one by one through the self-running trolley 4 and are arranged in a manner that the outer side faces of the two adjacent storage barrels 3 on the rotary table 2-1 are opposite to each other with the storage areas 2-11 in which the storage barrels 3 are placed on the rotary table 2-1 one by one, the storage barrels 3 on the rotary table 2-1 are in a ring shape, and obviously, the gaps between the two adjacent storage barrels 3 are smaller, so that the optimization of the space utilization of the refrigeration house 1 is achieved.
