[0033] Combined with Figure 1-2As shown in Figure 7, a non-contact intelligent storage cold storage with multiple stackers running on a single track includes: a cold storage shell 1, shelves 3, tracks 4, two stackers 5 and a control center 9. A freezing chamber 2 is opened in the cold storage shell 1, and the shelves 3 and tracks 4 are both arranged in the freezing chamber 2. Specifically, the track 4 is arranged in the middle of the bottom of the freezing chamber 2, and the shelves 3 are arranged on both sides of the track 4 in the freezing chamber 2. The two stackers 5 are both arranged on the track 4, and the two stackers 5 are driven and connected to the track 4. The stackers 5 are provided with encoders 30. Two entrances and exits 6 are opened on the cold storage shell 1. Two entry and exit platforms 7 are respectively arranged in the freezing chamber 2 near the two entrances and exits 6. When they are respectively located at both ends of the track 4, the positions of the two stackers 5 correspond to the two entrances and exits 6 respectively, and the two entry and exit platforms 7 are respectively located between the two entrances and exits 6 and the corresponding stackers 5. The two entrances and exits 6 are respectively provided with electric side sliding doors 8 corresponding to the two entrances and exits 6. The electric side sliding doors 8 are used to control the blocking of the corresponding entrances and exits 6. Preferably, the electric side sliding door 8 includes a side sliding door guide rail, a side sliding door driving mechanism and a side sliding door. The side sliding door guide rail and the side sliding door driving mechanism are arranged on the cold storage shell 1 and are located on the side of the corresponding entrance and exit 6. The side sliding door is slidably connected to the side sliding door guide rail. The size of the side sliding door corresponds to the entrance and exit 6. The side sliding door driving mechanism and the side sliding door driving mechanism are connected to the side sliding door driving mechanism. The connection is used to drive the side sliding door to move on the side sliding door guide rail so as to achieve the purpose of controlling the blocking of the corresponding entrance and exit 6 by the side sliding door. The control center 9 is arranged on the cold storage shell 1.

Preferably, the control center 9 includes an operation panel and a control processing module, wherein the control panel can be one or two. The operation panel is electrically connected to the control processing module. The control processing module is electrically connected to the two electric side sliding doors 8, the two stackers 5 and the encoders 30 located on the two stackers 5 respectively. The track 4 is provided with limit switches 31 at both ends and the middle position. Since the position of the shelf 3 is determined during installation, the positions of different storage places on the shelf 3 are determined, the length of the track 4 is determined, and the positions of the two stackers at the two ends of the track 4 are determined at the beginning, the corresponding relationship between different positions on the shelf 3 and the stacker 5 is set through the operation panel, so that the stacker 5 can be deployed according to the position of the taken items, and the working stroke of the electric sliding door 8 to cooperate with the stacker 5 to store and retrieve items is set. Since the encoder 30 is set, the encoder 30 can monitor the stroke of the corresponding stacker 5.

The control center 9 obtains the corresponding position information of the two stackers 5 so as to accurately determine the distance between the two stackers and the limit switch 31 so as to perform interference monitoring. When the stacker 5 approaches the limit switch 31, the stacker 5 starts to decelerate. When the stacker 5 touches the limit switch 31, the stacker 5 stops. Since the limit switch 31 is set, the travel of the stacker 5 is limited to avoid the collision of the two stackers 5. At the same time, according to the position information, the control center 9 can be used for trimming and optimization to make the subsequent movement more accurate and smooth.

While picking up item one, the other stacker 5 picks up item two. Since item one on the shelf 3 is already in a state of being picked up by the stacker 5, at this time item two is closest to the other stacker 5, and the other stacker 5 picks up item two Move to another access platform 7, and when item 1 is placed on the corresponding access platform 7, the corresponding electric side sliding door 8 releases the blockage of the corresponding access platform 7, so that the staff can take out the items on the access platform 7, and when item 2 is placed on another corresponding access platform 7, the corresponding electric side sliding door 8 releases the blockage of the corresponding access platform 7, so that the staff can take out the items on the access platform 7, and after the item 1 is taken out, the electric side sliding door 8 blocks the corresponding entrance and exit 6, and after the item 2 is taken out, the electric side sliding door 8 blocks the corresponding entrance and exit 6, when inventory is being carried out, taking two items as an example, the two items are placed on two access platforms 7 respectively, and the corresponding stackers 5 place the two items at the selected positions on the shelf 3 respectively, and then the two stackers 5 move to the end of the track 4.

By setting the first drive motor 18, the first drive motor 18 can drive the first movable seat 20 to move through the first screw 19 under the action of the threaded connection, and drive the first movable seat 20 to move toward the direction close to the two ends of the first strip slot seat 16. Similarly, by setting the second drive motor 23, the second drive motor 23 can drive the second movable seat 25 to move toward the direction close to the two ends of the second strip slot seat 21 through the second screw 24 under the action of the threaded connection. Since the first movable seat 20 and the second movable seat 25 can both move, the mounting plate 26 can be inserted into the shelves 3 on both sides of the track 4, so as to achieve the purpose of the stacker 5 being able to access the items on the shelves 3 on both sides of the track 4.

[0047] Combined with Figure 3As shown, a clamping cylinder 27 is provided on the mounting plate 26, and a clamping push rod 28 is connected to the output end of the clamping cylinder 27, and a clamping plate 29 is provided on the clamping push rod 28. The processor 12 is electrically connected to the clamping cylinder 27. By providing the clamping cylinder 27, the clamping plate 29 can be driven to move, and as the clamping plate 29 moves, the object can be clamped.

[0048] Combined with Figure 2 , 8 As shown, the encoder 30 is arranged on the opposite side of the two stacker base plates 11, and the encoder 30 is electrically connected to the processor 12. Since the encoder 30 is electrically connected to the processor 12, the encoder 30 can obtain the working information of the driving linear motor 10, so as to assist the control center 9 in setting the stroke of the stacker 5. Preferably, the processor 12 has a built-in alarm braking module. When the encoder 30 detects that the distance between the two stackers 5 is too close, the encoder 30 transmits information to the alarm braking module, and the alarm braking module issues an alarm and brakes the movement of the corresponding stacker 5.

[0049] Combined with Figure 7 As shown in FIG8 , the cold storage housing 1 also includes equipment to ensure the normal operation of the cold storage, including a refrigerator and a dehumidifier, etc. The refrigerator and the dehumidifier can also be adjusted by the control center 9 .

[0050] Working principle: During use, when it is necessary to take items on the shelf 3, with the help of the control center 9, the stacker 5 is moved to the corresponding item position on the shelf 3, and the items are taken and moved, and the items are placed on the entry and exit platform 7 corresponding to the stacker 5, and the electric side sliding door 8 corresponding to the entrance and exit 6 of the corresponding entry and exit platform 7 unblocks the entrance and exit 6, and the staff takes out the items on the entry and exit platform 7 through the entrance and exit 6, and then the electric side sliding door 8 blocks the entrance and exit 6. When inventory is being carried out, with the help of the control center 9, the electric side sliding door 8 unblocks the corresponding entrance and exit 6, and the staff places the items on the entry and exit platform 7, and then the corresponding stacker 5 takes the items and moves them to the selected vacant position on the shelf 3.
