As shown in fig. 1, the stereoscopic warehouse includes a stacker 2 and a plurality of warehousing units, and one or more warehousing units may be provided according to the warehousing capacity requirement. The plurality of stocker units may be arranged in a rectangular array or other arrangement.
The storage unit comprises four rows of shelves 1 arranged along a first direction X, each row of shelves 1 extends along a second direction Y, and the second direction Y is perpendicular to the first direction X in a horizontal plane. Two rows of middle goods shelves 1 set up at interval and form tunnel 3, and tunnel 3 extends along second direction Y, and stacker 2 is located the tunnel 3 of the storage unit who waits to carry out the warehouse entry task. Two rows of goods shelves 1 that are located the same side of tunnel 3 can adjacent contact setting, also can the interval setting. The goods shelf 1 is used for storing materials, and the materials can be finished cigarettes, cigarettes or tobacco raw materials and the like.

The first cargo space 11 and the second cargo space 12 of the two rows of racks 1 can be aligned front to back, the first cargo space 11 being located on the outside and the second cargo space 12 being located on the inside with respect to the roadway 3.
For the shelves 1 arranged in the form of a rectangular array, in the vertical plane of the shelves 1, the cargo spaces arranged in the second direction Y are called rows, the cargo spaces arranged in the third direction Z are called columns, and the cargo spaces at a certain height in the third direction Z are called floors.
Based on the stereoscopic warehouse, in some embodiments, the present disclosure provides a stereoscopic warehouse entry and exit method, as shown in fig. 2, including:
and 160, preferentially executing the ex-warehouse tasks for each goods position in the goods position set according to the preset ex-warehouse priority order.
Wherein, steps 120, 140 and 160 are performed sequentially and can be performed by the controller. In step 120, after receiving the ex-warehouse task, determining the earliest warehousing time Tmin of all the materials meeting the ex-warehouse conditions in the four rows of shelves 1 on the two sides of the roadway 3 in the warehousing unit, which may be from year, month, day to hour, or may also be from minute to second. In step 140, the preset time period T may be calculated according to hours or days, and all the cargo spaces whose warehousing time is within the range of [ Tmin, Tmin + T ] are considered to be in the earliest warehousing time period, which meets the earliest warehousing condition. In step 160, the goods in the goods space set are preferentially delivered, the whole meets the first-in first-out principle, and because a plurality of goods spaces meeting the earliest delivery condition exist, the plurality of goods spaces in the goods space set execute the delivery task according to the preset delivery priority order.
In the warehouse-out process in the prior art, the actual warehouse-in time of goods in each goods space is compared to determine the materials which are warehoused first, for example, the warehouse-in time is compared in units of seconds. When the stacker leaves the warehouse, no matter whether two goods spaces in the same row, the same column and the same layer store the same materials, the warehousing time of the second goods space is earlier than that of the first goods space, and unless the first goods space is a free goods space, the materials of the second goods space can be discharged after the materials of the first goods space are forcibly transferred to other goods spaces, so that the stacker needs to frequently execute the forced transferring task of the first goods space, and the warehouse leaving efficiency of the materials is seriously influenced.
In the stereoscopic warehouse entry and exit method disclosed by the embodiment of the disclosure, the goods positions meeting the exit conditions within the range of the entry time [ Tmin, Tmin + T ] are all considered as the goods positions meeting the earliest entry conditions, and the exit tasks are executed for the goods positions in the goods position sets according to the preset exit priority sequence, which is equivalent to prolonging the time interval for judging the goods positions meeting the earliest entry time. The method can not only meet the first-in first-out warehouse-out principle on the whole, but also reduce the probability of the stacker executing the forced warehouse-moving task of the first goods space, and improve the warehouse-out efficiency of the stacker.
For example, although the actual warehousing time of the second cargo space in the same row and column at the same height is earlier than that of the first cargo space, if the actual warehousing time difference between the two cargo spaces does not exceed T, the two cargo spaces are still considered to belong to the earliest cargo space, so that the first cargo space can be used for performing the ex-warehouse task, and then the second cargo space can be used for performing the ex-warehouse task.
