Mechanism and method for transferring cargo frame for refrigeration system

Abstract

The invention discloses a cargo frame transfer mechanism and method for a refrigeration system, comprising a transfer platform, a driving module and a control module. The carrier is used to transfer the cargo frame to or from the target rack. The transfer table is also connected to a detection module for detecting the position of the transfer table. The detection module feeds back the position detection signal to the control module, which is controlled by the control module. The moving platform moves, and the position coordinates of the target cargo frame are set as (x n ,y n ,z n ), the initial coordinate in the Z direction of the transfer stage is z n0 '=z n +μ 0 , the Z-direction end point coordinate of the transfer stage is z nn '=z n0 '‑μ 1 , by μ 0 and μ 1 The setting of these two safe moving distances ensures that the cargo frame can be safely transferred and transported. For the initialization method of the transfer platform, the control module implements different initializations according to whether the Y-direction in-position detection mechanism detects the position detection signal of the transfer platform. scheme to ensure the safety of the cargo box.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a cargo frame transfer mechanism and method for a refrigeration system. Background technique [0002] Because medical institutions such as blood stations and plasma collection stations do not conduct experiments in time after blood sample collection, they need to be refrigerated for storage. In the past, medical refrigerators were usually used for storage. There are many problems. For example, the storage capacity of refrigerators is limited. , The placement of the internal shelves is limited and messy. In the limited space, multiple refrigerators are often needed for storage, which wastes the space of the venue. [0003] In order to solve this problem, it is usually considered to use an automated refrigerated storage warehouse with a large storage space, set up shelves in the storage warehouse, set up blood boxes on the shelves to store blood bags, and realize the cold sto...

Problems solved by technology

[0002] Because medical institutions such as blood banks and plasma collection stations do not conduct experiments in time after the blood samples are collected, they need to be refrigerated. In the past, medical refrigerators were usually used for storage, and there were many problems. For example, the storage capacity of refrigerators is limited. , the placement of internal shelves is limited and messy, and multiple refrigerators are often required for storage in a limited space, wasting space on the site

[0003] In order to solve this problem, it is usually considered to use an automated refrigerated storage room with a large storage space. Shelves are set up in the storage room, and blood boxes are set on the shelves to store blood bags, and the transfer manipulator is used to realize the storage of blood in the cold storage room in a low-temperature environment. The blood samples stored on the shelves are freely transferred to and from the warehouse. In the prior art, a blood frame tray is usually set up immediately in front of the shelf, and the blood frame is first transferred to the tray in front of the shelf by the transfer manipulator, and then transferred by the transfer manipulator. Grab and transfer, through the setting of the blood frame tray, it is ensured that the blood frame will not fall in the air during normal transfer or power failure during the transfer process. However, the blood frame tray of this solution occupies a large area and the space utilization rate Low, in order to improve the utilization rate of the cold storage space, it is necessary to consider removing the blood frame tray next to the shelf to make full use of its occupied space, and to set up multiple rows of shelves in the cold storage. Therefore, it is necessary to design a The blood frame transfer mechanism between the shelves, at the same time, can ensure that the blood frame transfer mechanism can be safely initialized after any abnormal power failure and power on again
