In one possible embodiment, the access system further comprises a control unit in signal connection with the cargo lifting unit 20 and the shuttle unit 30, respectively; the control unit is used to control the shuttle unit 30 and the lifting platform 21 to move simultaneously so that the lifting platform 21 is aligned with the shuttle unit 30 when the shuttle unit 30 moves to the goods delivery location 13.

Specifically, referring to fig. 4 and 5, respectively, in this embodiment, the movement of the shuttle unit along the roadway and the lifting of the lifting platform along the second direction are controlled by the control unit; and when the goods are put in and taken out of the warehouse, the control unit simultaneously dispatches the shuttle vehicle unit and the lifting platform, namely the control unit controls the shuttle vehicle unit and the lifting platform to move simultaneously, so that when the shuttle vehicle unit moves to the goods transfer position, the lifting platform is aligned with the shuttle vehicle unit simultaneously, and then the goods can be transferred immediately.

Conveniently understand, this embodiment is on the basis of omitting the buffer position, dispatches shuttle unit and elevating platform simultaneously through the control unit, can make and carry out the transportation of goods immediately when elevating platform and shuttle unit align to solved because the lower problem of warehouse entry and exit operating efficiency that leads to of existence of buffer position, reduced the activity duration of warehouse entry and exit operation, improved the operating efficiency.

Specifically, a case where the control unit can improve the efficiency of cargo loading and unloading work by simultaneously scheduling the shuttle unit and the elevating platform on the basis of omitting the buffer space will be described in detail below.

Referring first to fig. 1 to 3, fig. 1 to 3 show the position of a buffer position 15 in the prior art, that is, the buffer position is disposed at one end of a sub-shelf close to a goods lifting unit. In the prior art, due to the existence of the buffer position, the shuttle unit can be used for temporarily placing the goods, and the shuttle unit does not have direct contact with the goods lifting unit, for example, the shuttle unit places the goods at the buffer position, then the lifting platform takes the goods away from the buffer position, or vice versa, the lifting platform places the goods at the buffer position, then the shuttle unit takes the goods away from the buffer position; therefore, in the prior art, the control unit does not make a request for the shuttle unit and the lifting platform to reach the buffer position at the same time, that is, the shuttle unit and the lifting platform can reach the buffer position one by one according to respective moving efficiency, at this time, please refer to fig. 6 and 7, and fig. 6 and 7 respectively show the warehousing and ex-warehouse operation flows of goods in the prior art.

Secondly, as can be conveniently understood from fig. 6 and 7, the overall efficiency of the cargo warehousing operation is mainly determined by the shuttle unit and the cargo lifting unit, and can be divided into three cases, one of which is that the efficiency of the shuttle unit is smaller than that of the cargo lifting unit, for example, the number of the shuttle units is smaller or the speed is lower, the overall efficiency is determined by the shuttle unit, the other one is that the efficiency of the shuttle unit is greater than that of the cargo lifting unit, for example, the number of the shuttle units is greater or the speed is higher, the overall efficiency is determined by the cargo lifting unit, the third one is that the efficiency of the shuttle unit is equal to that of the cargo lifting unit, and the overall efficiency is determined by the shuttle unit or the cargo lifting unit.

The total time for the shipment and storage under the above three conditions will be analyzed.

(1) The efficiency of the shuttle unit is equal to the efficiency of the cargo lifting unit, at this time please refer to table 1 below:

for warehousing operation, the total time is T (in 1) ═ T11+ T21+ T31+ T41;

for ex-warehouse operation, the total time is T (out 1) ═ T12+ T21+ T32+ T41;

table 1 when the efficiency of the shuttle unit is equal to that of the goods lifting unit, the flow of goods out of and into the warehouse and the time spent

(2) The efficiency of the shuttle unit is less than the efficiency of the cargo lifting unit, and at this time, please refer to table 2 below:

for warehousing operation, the total time is T (in 2) ═ T11+ T21+ Tw1+ T31+ T41;

that is, when there is a buffer bit, after T21, the cargo lift unit can perform the next task, but since the efficiency of the shuttle unit is less than that of the cargo lift unit, the cargo lift unit needs to wait for the shuttle unit to complete the previous job;

for ex-warehouse operation, the total time is T (out 2) ═ T (out 1) ═ T12+ T21+ T32+ T41;

that is, for the warehouse-out operation, since the efficiency of the cargo lifting unit is higher than that of the shuttle unit, the cargo lifting unit does not need to wait at this time;

table 2 when the efficiency of the shuttle unit is less than that of the goods lifting unit, the flow of goods out of and into the warehouse and the time spent

(3) The efficiency of the shuttle unit is greater than the efficiency of the cargo lifting unit, and at this time, please refer to table 3 below:

for warehousing operation, the total time is T (in 3) ═ T (in 1) ═ T11+ T21+ T31+ T41;

that is, for warehousing operations, since the efficiency of the shuttle unit is higher than that of the cargo lifting unit, the shuttle unit does not need to wait at this time;

for ex-warehouse operation, the total time is T (out 3) ═ T12+ T21+ Tw2+ T32+ T41;

that is, when there is a buffer bit, after T41, the shuttle unit may perform the next task, but since the efficiency of the cargo lifting unit is less than the efficiency of the shuttle unit, the shuttle unit needs to wait for the cargo lifting unit to complete the previous job;

table 3 when the efficiency of the shuttle unit is greater than that of the goods lifting unit, the flow of goods out of and into the warehouse and the time spent

In any case, the existence of the cache bit does not improve the overall efficiency, but also increases the system cost and reduces the storage density.

In this embodiment, on the basis of omitting the buffer location, the control unit simultaneously schedules the shuttle unit and the lifting platform, so that the cargo can be immediately transported when the cargo lifting unit is aligned with the shuttle unit, at this time, please refer to fig. 8 and 9, where fig. 8 and 9 respectively show the cargo warehousing and warehousing operation flow of this embodiment, and refer to the following table 4 specifically:

for warehousing operation, the total time is T (in 0) ═ T11+ T61+ T41;

for ex-warehouse operation, the total time is T (out 0) ═ T51+ T21+ T12;

table 4 this embodiment saves the time and the process of warehousing and warehousing goods when the buffer bit is saved

Because the control unit dispatches the shuttle unit and the lifting platform to arrive at the same time, namely T61 is smaller than T21+ T31, and T51 is smaller than T32+ T41, the operation time can be saved and the operation efficiency can be improved compared with the buffer position.
