Technical Field

The invention belongs to the technical field of shuttle scheduling of warehousing systems, and particularly relates to an avoidance structure, an avoidance-type goods shelf and an avoidance method of a shuttle running in the same direction under a dense warehousing condition.

Background

Under the intensive warehouse condition, efficient cargo warehouse-in and warehouse-out operation scheduling is needed, but under the condition of a plurality of shuttling vehicles, the shuttling vehicles run in the same direction so as to greatly restrict efficient warehouse-in and warehouse-out operation. A large number of scheduling algorithms have been developed at present to solve the problems of shuttle scheduling and cargo handling efficiency improvement under the intensive storage condition, but the shuttle scheduling effect is poor when a plurality of shuttles exist in the intensive storage space. How to solve the problem of the efficiency of goods in and out of storage under the existing intensive storage condition through avoiding the shuttle car is one of the important challenges currently faced.

The difficulty in solving the above problems is that: in existing storage racks, the shuttle travel rail (main rail) is typically located between two rows of racks. The shuttle can not avoid in the vertical and track directions, if the shuttle is avoided downwards, the space at the bottom of the goods shelf is narrow, and when the shuttle enters the bottom of the goods shelf to avoid, great difficulty exists.

Detailed Description

The present invention will be described in further detail with reference to fig. 1 to 12. The original structure of the goods shelf is shown in fig. 1, and the shuttle 4 can only travel in a straight line in a fixed track, if the shuttle 4 on the same track is encountered, the shuttle cannot avoid.

In order to enable two shuttles 4 on the same track to avoid, the invention discloses an avoidance structure, an avoidance type goods shelf and an avoidance method of the shuttles 4 running in the same direction, wherein the structure part comprises a main track 2 arranged on the goods shelf 1, the shuttles 4 moving along the main track 2, an avoidance track 3 arranged on the goods shelf 1 and an avoidance mechanism 5 moving along the avoidance track 3.

The avoidance rail 3 is arranged right below the main rail 2 and is used for the movement of the carrier 53 of the avoidance mechanism 5; the shuttle 4 is provided with wheels 41 movable on the main track 2, the wheels 41 of the shuttle 4 being capable of effecting a track change by moving along the spline. Fig. 4 is a wheel track of the shuttle 4 when traveling with normal cargo, and fig. 5 is a wheel track of the shuttle 4 when performing the avoidance function.

The avoiding mechanism 5 comprises a carrier 53 arranged on the avoiding track 3, a lifting mechanism 52 arranged on the carrier 53 and a supporting plate 51 arranged on the lifting mechanism 52; the bearing vehicle 53 moves along the avoidance rail 3 and is responsible for conveying the avoidance mechanism 5 to the lower part of the position where the shuttle vehicle 4 needs to avoid; the lifting mechanism 52 is responsible for driving the supporting plate 51 to lift; the pallet 51 is responsible for supporting the shuttle 4.

The avoidance method in the invention is as follows:

1. As shown in fig. 6, the shuttle 4 runs along the main track 2, when the system recognizes the position of the shuttle 4 to be avoided, the avoiding mechanism 5 moves under the shuttle 4 under the driving of the carrier 53 (the shuttle 4 runs along the avoiding track 3 under the main track 2);

2. as shown in fig. 7, the lifting mechanism 52 drives the pallet 51 to rise to the height of the shuttle 4;

3. As shown in fig. 8, the wheel track of the wheels 41 of the adjusting shuttle 4 is shortened and the wheels are brought into contact with the ascending pallet 51, i.e., the whole shuttle 4 is transferred onto the pallet 51;

4. as shown in fig. 9, the lifting mechanism 52 drives the supporting plate 51 and the shuttle 4 to integrally descend, so that the main track 2 is free, and the function of avoiding the shuttle 4 is realized;

After the shuttle 4 is avoided, the invention also performs the following functions:

1. As shown in fig. 10, the shuttle 4 and the pallet 51 are driven by the lifting mechanism 52 to rise to the height of the main rail 2;

2. as shown in fig. 11, the tread of the shuttle 4 increases, so that the wheels 41 contact the main rail 2, i.e., the shuttle 4 returns to the main rail 2;

3. As shown in fig. 12, the pallet 51 is lowered and separated from the shuttle 4, and the shuttle 4 continues to travel on the main rail 2, and the avoidance mechanism 5 stands by for the next avoidance.

The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
