Description

Multi-interface cargo transferring device and freight storage system comprising same Technical Field The invention relates to the technical field of logistics transportation equipment, in particular to a multi-interface cargo transferring device and a cargo storage system formed by the same. Background In order to improve the logistics transportation efficiency, the mobile robot has a multi-layer temporary storage form, but the goods taking and placing form is mainly one by one. In order to improve greater cargo transportation efficiency, the mobile robot is matched with the cargo transferring device, so that the purpose of taking and placing cargoes by the multi-layer temporary storage layer plates of the mobile robot can be achieved. However, some existing cargo transferring devices (multi-comb-tooth equidifference lifting transferring device, hooking transferring device and side equidistant lifting transferring device) have the defects of low cargo transferring efficiency, low space utilization rate, high cost and the like due to a series of reasons that only one side can be in butt joint with a mobile robot, the structure is complex and the like. The three-dimensional warehouse system and the freight warehouse method thereof with the application number of CN113859840A comprise a freight robot and a three-dimensional goods shelf, wherein the freight robot comprises an automatic guide vehicle and a goods shelf climbing machine, a loading device is arranged on the automatic guide vehicle, the automatic guide vehicle carries the goods shelf climbing machine through the loading device, the three-dimensional goods shelf comprises a warehouse frame unit, a rail unit and a docking station, the rail unit is arranged on one side of the warehouse frame unit, the docking station is arranged below the rail unit, and after the goods shelf climbing machine carried by the automatic guide vehicle enters the docking station, the goods shelf climbing machine enters the rail unit to be separated from the loading device, and returns to the loading device through the rail unit after moving to a goods storage area of the warehouse frame unit to take the goods to be docked. The scheme is that the goods are transferred through the three-dimensional goods shelves and the freight robot, but the goods taking and placing mode is mainly one by one in the scheme. Due to a series of reasons of only one side being capable of being in butt joint with the mobile robot, the structure is complex, and the like, the defects of low cargo carrying efficiency, low space utilization rate, high cost and the like exist. Disclosure of Invention Aiming at the problems of low carrying efficiency, low space utilization rate and the like in the prior art mentioned in the background art, the invention provides a multi-interface cargo transferring device and a cargo storage system formed by the same, wherein the cargo height is controlled by a lifting type cargo conveying mechanism, and cargo handling actions are carried out by utilizing a plurality of cargo interfaces matched with cargo conveying units, so that the effective utilization of the circumferential space of the multi-interface cargo conveying device is realized, the carrying efficiency is obviously improved, and the market competitiveness is increased. In order to achieve the above purpose, the present invention adopts the following technical scheme: The multi-interface cargo transferring device comprises a rack, wherein a lifting cargo conveying mechanism is arranged on the rack and comprises a plurality of layers of lifting modules which are distributed along the longitudinal distance; The lifting module is provided with a cargo carrying and conveying unit at the edge; the lifting type cargo conveying mechanism comprises a driving device arranged on the frame, and the driving device drives the lifting module to move in a lifting mode. The lifting type cargo conveying mechanism utilizes the driving mechanism to control the lifting module to perform up-and-down motion so as to lift and lower the cargo, and the cargo conveying unit is used for supporting the cargo and controlling the cargo to enter and exit the lifting module from the cargo interface, so that the lifting type cargo conveying mechanism can bear cargo transferring work. Further, the cargo carrying unit can move forward or backward along the length direction, and the cargo carrying unit is provided with a cargo positioning module. The cargo carrying unit is used as an actuating mechanism at the cargo interface to respectively control the in-out motion of the cargo through forward and reverse motions, and meanwhile, the cargo positioning module is used for ensuring that the cargo is fed and then moves to the middle part of the lifting module so as to ensure the balance of the gravity center, and the phenomenon that the bearing is uneven is avoided to be toppled over or damaged locally. Preferably, the transferring roller lines are
