automatic mail access system

Abstract

The invention provides an automatic storage and retrieval system for a letter. The automatic storage and retrieval system comprises a storage rack, a presorting mechanism and a delivery mechanism; oneside of the storage rack is provided with a plurality of storage tanks for storing letters, and the other side of the storage rack is provided with grooves communicating with the storage tanks; eachstorage tank correspond to the groove, and the length of the grooves is smaller than the length of the storage tank; and the presorting mechanism comprises first pushing components used for extendinginto the grooves to push out a part of or all target letters from the storage tanks, and the delivery mechanism is used for acquiring the letters pushed out from the storage tanks by the presorting mechanism. According to the system, the letters can be taken out from the storage rack and delivered to those who fetch the letters, and letters of those who store the letters are stored in the storagerack; through setting a part of or all storage spaces of the storage rack for specially storing thinner articles, such as letters, the space utilization rate of the storage rack is improved; meanwhile, the letters are stored and delivered through a robot or a conveyor belt according to the conditions, and the presorting mechanism is controlled to locate the target letters; the function of full-automatic storage and retrieval is achieved, and the storage and retrieval efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of logistics transportation, in particular to an automatic access system for letters. Background technique [0002] Goods storage refers to the general term for the temporary storage and storage of goods in order to ensure the normal production and consumption of goods in the process of circulation, and it is also an important work link of logistics. A common way to store goods is to sort the goods by category and store them on the corresponding storage racks. However, in the current cargo storage and retrieval system, there is no sorting by category according to the thickness of the goods, nor is there any thickness for the thickness of the goods. Set up a special storage shelf for thinner goods or set up a special storage area in the storage shelf, so when there are a lot of items such as envelopes in the stored goods, an envelope will occupy a large storage space grid, reducing space utilization.
