High-efficiency cold storage equipment with automated loading and unloading

Abstract

This utility model discloses a highly efficient cold storage device for automated loading and unloading, including a frame with an inlet / outlet on one side and temporary storage racks at the inlet / outlet. Multiple storage racks are arranged in layers inside the frame. A lifting mechanism is located inside the frame and outside the storage racks, maintaining lifting and lowering. A linear movement mechanism is mounted on the lifting mechanism and passes through the gaps between the temporary storage racks for both lifting and linear movement. This cold storage device, by incorporating the lifting and linear movement mechanisms within the frame, facilitates the automatic loading and unloading of fruit and vegetable crates from the temporary storage racks to each storage rack. The temporary storage racks also allow for easy docking with an external automated conveyor system, enabling automated loading and unloading of the fruit and vegetable crates.

Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable storage and preservation technology, specifically to a high-efficiency preservation warehouse device with automated loading and unloading. Background Technology

[0002] In the fruit and vegetable supply chain, preservation and storage are crucial for maintaining the quality of fruits and vegetables. Low-temperature cold storage is widely used because it can effectively inhibit the respiration of fruits and vegetables and slow down their metabolism. To improve the space utilization of cold storage and ensure uniform air circulation, fruits and vegetables are usually placed in crates and then stored in layers on shelves. Cooling is achieved through the flow of cold air between the shelves.

[0003] However, the current placement box access operation still has significant technical shortcomings:

[0004] Firstly, the storage and retrieval process relies on a combination of manual labor and traditional handling equipment, which is inefficient and labor-intensive. Specifically, operators must first move the crates filled with fruits and vegetables to a forklift or lift trolley, manually drive the equipment to the target shelf location, and then manually move the crates onto the shelf support plate; retrieving them requires repeating the above process in reverse. In this process, the handling of the crates, the positioning of the equipment, and the alignment with the shelf all depend on manual operation, which is not only time-consuming and labor-intensive, but also inconvenient for quickly storing and retrieving fruits and vegetables on higher shelves, posing significant safety hazards.

[0005] Secondly, frequent manual entry and exit disrupts the temperature control stability of cold storage facilities. Cold storage facilities need to maintain a specific low-temperature environment, but each time operators enter and exit, they bring in external heat, causing temperature fluctuations inside the storage facility. Especially in scenarios with high-frequency storage and retrieval, the temperature fluctuations are significant, disrupting the optimal low-temperature conditions for fruit and vegetable storage, accelerating dehydration, mold growth, and other quality deterioration, and seriously affecting storage quality. Utility Model Content

[0006] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides an efficient cold storage device for automated loading and unloading. The cold storage device has a reasonable arrangement of placement racks, lifting mechanisms and linear movement mechanisms in the frame to facilitate the automatic transportation of fruit and vegetable placement boxes to the corresponding placement racks for storage and retrieval. At the same time, the frame is equipped with inlets and outlets and temporary storage racks to facilitate docking with external conveying equipment and realize the automatic picking and placing of fruit and vegetable placement boxes.

[0007] This utility model is implemented as follows: a high-efficiency cold storage device for automated loading and unloading is constructed, including a frame, an inlet and outlet on one side and a temporary storage rack set at the inlet and outlet, and multiple storage racks arranged in layers inside the frame.

[0008] The lifting mechanism is located inside the frame and outside the placement frame to maintain lifting.

[0009] A linear motion mechanism is installed on the lifting mechanism and moves vertically and linearly through the gaps between the temporary storage racks.

[0010] Preferably, the placement frame includes two opposing placement plates with an L-shaped cross-section. Limiting plates and material inlets are respectively provided on the supporting parts of the placement plates. One end of the placement plate is fixed to the frame to maintain cantilever support. Reinforcing ribs that are fixed to the frame are also provided on the outer side of the placement plate.

[0011] Preferably, the lifting mechanism includes a first transmission belt that is vertically distributed and rotates at the inner end of the frame body. The first transmission belt drives the lifting frame to lift and lower through a drive motor and transmission mechanism located at the bottom of the frame body. A first roller is provided on the side of the lifting frame to keep in contact with and roll the uprights of the frame body. The linear movement mechanism is located on the top of the lifting frame and moves linearly along the length of the lifting frame.

[0012] Preferably, a second transmission belt and a third transmission belt are also provided inside the lifting frame. The third transmission belt is arranged along the length of the lifting frame and keeps rotating. The second transmission belt is driven by a drive motor and a transmission mechanism to keep the third transmission belt rotating. The linear movement mechanism is driven by the third transmission belt to perform linear movement.

[0013] Preferably, the linear motion mechanism includes a base plate and second rollers disposed at the four corners of the base plate. The second rollers contact the lifting frame and roll. The base plate is connected to a third transmission belt. A support frame is disposed on the base plate. Material receiving clamps passing through the material receiving port are disposed on the two opposite sides of the support frame. Limiting clamps are disposed on the other two sides of the support frame.

[0014] Preferably, a conveyor is also provided on the temporary storage rack.

[0015] Preferably, it also includes a control device, which controls the forward and reverse rotation and stopping of the first transmission belt, the second transmission belt, and the conveyor.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This cold storage facility utilizes a tiered arrangement of placement racks and temporary storage racks within its structure. Through the coordinated operation of lifting and linear motion mechanisms with the frame, it achieves fully automated transport of placement frames from temporary storage racks to the target placement racks, eliminating the need for manual handling or operating forklifts / trolleys. This effectively improves the turnover efficiency of fruit and vegetable storage while completely solving the problem of high-intensity manual labor.

[0018] By reducing the frequency of manual entry and exit from the cold storage, the handover of the placement frames is completed only by connecting the external equipment with the temporary storage rack. This reduces the temperature fluctuation range inside the storage, avoids problems such as increased respiration and dehydration of fruits and vegetables caused by sudden temperature rises, and significantly improves the stability of storage quality.

[0019] It also reduces the number of workers in low-temperature environments, reduces the health impact of long-term low-temperature work, and reduces the occurrence of damage to fruit and vegetable placement frames and other situations caused by human error, thereby reducing management costs and material losses.
