Description

Technical Field

[0001] The present invention relates to the technical field related to the distribution of warehouse goods, and in particular to a method for allocating goods storage locations and a system for allocating goods storage locations. Background Art

[0002] An automated stereoscopic warehouse is a high-rise warehouse system for storing goods in multiple layers. It mainly consists of high-rise shelves, aisles (tracks), aisle stackers, in-out conveying equipment, and an automatic control and management system. The stacker and the in-out equipment can automatically complete the in-out operations of goods, automatically manage the goods under computer management, and be connected to the enterprise management system to achieve modern management, which is an important component for an enterprise to achieve modern management.

[0003] Currently, when multiple shuttle cars transport the same goods from different positions to the goods storage locations in the same goods placement area, the goods are strictly stored according to the specified target goods storage locations. During the inbound process, the following may occur: when a shuttle car enters the shelf aisle and transports the goods to the entrance on one side of the specified goods storage location, it may block other shuttle cars from passing. Refer to the attached drawings Figure 1 、 Figure 4 As shown, for example, goods B1 are to be stored in goods storage location A1, and goods B2 are to be stored in goods storage location A2. Goods B1 and goods B2 are of the same type. The shuttle car transporting goods B1 receives the task first and departs first. However, the distance between goods B1 and the corresponding goods storage location A1 is farther than the distance between goods B2 and the corresponding goods storage location A2. As a result, the shuttle car transporting goods B2 enters the goods aisle first for inbound and blocks the shuttle car transporting goods B1 from passing and entering the entrance of the corresponding goods storage location A1. This requires the shuttle car transporting goods B1 to wait outside the shelf aisle and enter after the shuttle car transporting goods B2 leaves the shelf aisle. This will cause the inbound speed of the goods to be slower and affect the inbound efficiency of the goods. In addition, during the transportation of the goods, the following situation may exist. Refer to the attached drawings Figure 1 、 Figure 2 As shown, the first aisle where the shuttle car transporting goods B1 walks before entering the shelf aisle is perpendicular to the shelf aisle, and the second aisle where the shuttle car transporting goods B2 walks before entering the shelf aisle is in the same straight line as the shelf aisle. When there is a collision situation between the shuttle car transporting goods B1 and the shuttle car transporting goods B2 at the entrance of the shelf aisle, the WCS controls the shuttle car transporting goods B2 to decelerate or stop, and first allows the shuttle car transporting goods B1 to enter the shelf aisle, and then the shuttle car transporting goods B2 enters the goods aisle to avoid the shuttle car transporting goods B2 entering the shelf aisle first and blocking the shuttle car transporting goods B1 from passing and entering the entrance of the corresponding goods storage location A1. Although this avoids the occurrence of blocking situations, the shuttle car transporting goods B2 decelerating or stopping in advance will delay a certain inbound time and also affect the inbound efficiency. Summary of the Invention

[0004] In order to overcome the existing technical defects and solve the technical problems that multiple shuttles store the same goods on the storage locations in the same goods placement area and the storage efficiency is relatively slow, the purpose of the present invention is to provide a method for allocating goods storage locations to solve the above technical problems.

[0005] The technical solution adopted by the present invention to solve the technical problems is as follows:

[0006] According to one aspect of the present invention, a method for allocating goods storage locations is designed, including:

[0007] Establish a shelf, on which there are at least two storage entrances, as well as a connected first roadway, a second roadway and a shelf roadway;

[0008] Obtain information of several goods to be stored;

[0009] Allocate corresponding goods storage locations based on the information of several goods to be stored;

[0010] According to the current position of the goods to be stored and the position of the allocated goods storage location, confirm the corresponding goods transportation path;

[0011] The shuttle transports the goods according to the corresponding goods transportation path;

[0012] If the corresponding storage locations of two identical goods B1 and B2 in the same goods placement area are storage location A1 and storage location A2 of goods,

[0013] When the shuttle transporting goods B1 and the shuttle transporting goods B2 enter the shelf roadway successively without obstruction, they are respectively stored normally;

[0014] When the shuttle transporting goods B2 enters the shelf roadway before the shuttle transporting goods B1 and blocks the shuttle transporting goods B1, the WCS reallocates the storage locations of goods B1 and B2, changes the corresponding storage location A2 of goods B2 to storage location A1, and the corresponding storage location A1 of goods B1 to storage location A2. The shuttle transporting goods B2 transports goods B2 to the entrance of storage location A1 for storage, and the shuttle transporting goods B1 transports goods B1 to the entrance of storage location A2 for storage.

[0015] By adopting the above technical solution, when the shuttle transporting goods B2 enters the shelf roadway before the shuttle transporting goods B1 and blocks the shuttle transporting goods B1, the WCS reallocates the storage locations of goods B1 and B2, solves the blocking problem, thereby improving the goods storage speed and efficiency, and at the same time ensuring that the same goods on the two shuttles are transported to the same goods placement area for storage.

[0016] To better solve the above technical defects, the present invention also has a better technical solution:

[0017] In some embodiments, the first lane is perpendicular to the shelf lane, and the second lane is in the same straight line as the shelf lane. When there is a collision situation between the shuttle for transporting goods B1 and the shuttle for transporting goods B2 at the entrance of the shelf lane, the WCS controls the shuttle for transporting goods B1 to decelerate or stop, and first allows the shuttle for transporting goods B2 to enter the shelf lane, and then the shuttle for transporting goods B1 enters the goods lane.

[0018] When the shuttle for transporting goods B2 and the shuttle for transporting goods B1 enter the shelf lane successively without obstruction, they are respectively normally stored in the warehouse.

[0019] When the shuttle for transporting goods B2 enters the shelf lane and blocks the shuttle for transporting goods B1, the WCS reallocates the storage locations of goods B1 and goods B2, changes the storage location A2 corresponding to goods B2 to storage location A1, and the storage location A1 corresponding to goods B1 to storage location A2. The shuttle for transporting goods B2 transports goods B2 to the entrance of storage location A1 for warehousing, and the shuttle for transporting goods B1 transports goods B1 to the entrance of storage location A2 for warehousing. Thus, when there is a collision situation between the shuttle for transporting goods B1 and the shuttle for transporting goods B2 at the entrance of the shelf lane, the WCS controls the shuttle for transporting goods B1 to decelerate or stop, first allows the shuttle for transporting goods B2 to enter the shelf lane, eliminates the reduction or parking waiting of the shuttles on the same straight line as the shelf lane, improves the passing efficiency and the warehousing efficiency, and then the WCS reallocates the storage locations of goods B1 and goods B2 to solve the blocking problem, improves the warehousing speed of goods, improves the warehousing efficiency, and at the same time ensures that the same goods on the two shuttles are transported to the same goods placement area for storage.

[0020] In some embodiments, the storage location A1 and the storage location A2 are adjacent storage locations.

[0021] In some embodiments, the storage location A1 and the storage location A2 are non - adjacent storage locations.

[0022] According to another aspect of the present invention, a storage location allocation system for goods is designed, including: a shelf, shuttles, and a WCS. The shelf is provided with at least two warehousing entrances, as well as a first lane, a second lane, and a shelf lane that are connected and allow the shuttles to run. There are multiple shuttles, and the wireless transmission module on each shuttle performs two - way data communication with the wireless transmission module on the WCS, and the WCS controls the operation of the shuttles.

[0032] ReferenceFigures 1 to 6 As shown, a method for allocating cargo storage locations provided by the present invention includes:

[0033] A shelf 1 is established. The shelf 1 is provided with two or three or four or more inbound ports 10, as well as a first roadway 11, a second roadway 12 and a shelf roadway 13 that are connected and for the shuttle vehicle to run. The first roadway 11 is perpendicular to the shelf roadway 13, and the second roadway 12 is in the same straight line as the shelf roadway 13;

[0034] The WCS obtains information on a number of goods to be warehoused;

[0035] The WCS allocates corresponding cargo storage locations based on the information on a number of goods to be warehoused;

[0036] The WCS determines the corresponding cargo transportation path according to the current position of the inbound goods and the position of the allocated cargo storage location; the current position is known as the position of the inbound port.

[0037] The WCS controls multiple shuttle vehicles to transport goods according to the corresponding cargo transportation path; among them, the wireless transmission modules on the shuttle vehicles are in two-way data communication with the wireless transmission module on the WCS. The operation of the shuttle vehicles is controlled by the WCS. The shuttle vehicles are provided with positioning modules, which feedback the position information to the WCS in real time, and the real-time position of the shuttle vehicles is monitored through the WCS;

[0038] If the corresponding storage locations for two identical goods B1 and B2 in the same cargo placement area are cargo storage location A1 and cargo storage location A2; among them, cargo storage location A1 and cargo storage location A2 are adjacent storage locations, or they can also be non-adjacent storage locations. In this embodiment, it is preferred that cargo storage location A1 and cargo storage location A2 are adjacent storage locations;

[0039] Reference Figures 1 to 3 As shown, when the shuttle vehicle transporting goods B1 and the shuttle vehicle transporting goods B2 enter the shelf roadway 13 successively without obstruction, that is, the shuttle vehicle transporting goods B1 departs first and enters the shelf roadway 13 first, and the shuttle vehicle transporting goods B2 enters the shelf roadway 13 later, then they are warehoused normally. The shuttle vehicle transporting goods B1 transports goods B1 to the entrance 131 of cargo storage location A1 for the roadway stacker to pick up and warehouse, and the shuttle vehicle transporting goods B2 transports goods B2 to the entrance 132 of cargo storage location A2 for the roadway stacker to pick up and warehouse;

[0040] Reference Figure 1 、 Figure 4 、 Figure 5As shown in the figure, when the shuttle vehicle for transporting goods B2 enters the shelf aisle 13 ahead of the shuttle vehicle for transporting goods B1 and blocks the shuttle vehicle for transporting goods B1, that is, the shuttle vehicle for transporting goods B1 departs first. Due to the long distance, the shuttle vehicle for transporting goods B2 enters the shelf aisle 13 earlier than the shuttle vehicle for transporting goods B1, resulting in the shuttle vehicle for transporting goods B2 blocking the shuttle vehicle for transporting goods B1. The WCS reallocates the storage locations of goods B1 and goods B2, changing the storage location A2 corresponding to goods B2 to storage location A1, and the storage location A1 corresponding to goods B1 to storage location A2. Then, the WCS controls the shuttle vehicle for transporting goods B2 to transport goods B2 to the entrance 131 of storage location A1 for the aisle stacker to pick up and store in the warehouse, and the shuttle vehicle for transporting goods B1 transports goods B1 to the entrance 132 of storage location A2 for the aisle stacker to pick up and store in the warehouse;

[0041] When there is a risk of collision between the shuttle vehicle for transporting goods B1 and the shuttle vehicle for transporting goods B2 at the entrance of the shelf aisle 13, the WCS controls the shuttle vehicle for transporting goods B1 to decelerate or stop, allowing the shuttle vehicle for transporting goods B2 to enter the shelf aisle 13 first and then the shuttle vehicle for transporting goods B1 to enter the goods aisle 13;

[0042] When the shuttle vehicle for transporting goods B2 and the shuttle vehicle for transporting goods B1 enter the shelf aisle 13 successively without obstruction, refer to Figure 6 shown, then they are stored in the warehouse normally respectively;

[0043] When the shuttle vehicle for transporting goods B2 enters the shelf aisle 13 and blocks the shuttle vehicle for transporting goods B1, refer to Figure 4 、 Figure 5 shown, the WCS reallocates the storage locations of goods B1 and goods B2, changing the storage location A2 corresponding to goods B2 to storage location A1, and the storage location A1 corresponding to goods B1 to storage location A2. The shuttle vehicle for transporting goods B2 transports goods B2 to the entrance 131 of storage location A1 for the aisle stacker to pick up and store in the warehouse, and the shuttle vehicle for transporting goods B1 transports goods B1 to the entrance 132 of storage location A2 for the aisle stacker to pick up and store in the warehouse.
