Description

TECHNICAL FIELD

[0001] The present application relates to the field of logistics and warehousing, in particular to an intelligent finished product warehouse system with bidirectional warehouse-in and warehouse-out buffer. BACKGROUND

[0002] With the rapid development of intelligent manufacturing and logistics industry, intelligent finished product warehouse, also known as automated vertical warehouse, has become the core of modern enterprise warehousing. Intelligent finished product warehouse can realize high-density storage and automated warehouse-in and warehouse-out of goods through automatic equipment such as stacker, conveying line, automatic loading machine, etc., significantly improving space utilization and operation efficiency.

[0003] However, in actual operation, such systems often have low work efficiency. For example, the system is forced to directly issue goods to the automatic loading buffer line due to insufficient buffer space before determining whether the incoming vehicle can be automatically loaded. Once the vehicle is not suitable for automatic loading, such as vehicle model mismatch or improper parking, the goods will block the loading line, causing subsequent operation to be interrupted. Moreover, intelligent finished product warehouse is generally designed to prioritize automatic loading and supplement manual loading. When the automatic loading machine malfunctions, switching to manual mode usually requires manual task resetting, goods handling and data entry, which is time-consuming and inefficient.

[0032] In addition, in the description of the present application, the term "multiple" means two or more, unless specifically defined otherwise.

[0033] In some embodiments, Figure 1 and Figure 2For example, a kind of intelligent finished product warehouse system with two-way warehousing and outbound buffer provided by the application is described and introduced.The intelligent finished product warehouse system with two-way warehousing and outbound buffer provided by the application includes warehousing conveying line 200, outbound conveying line 300, finished product storage rack 100, automatic loading area 500, manual loading area 600 and outbound buffer area 400.The finished product storage rack 100 is arranged between the downstream of the warehousing conveying line 200 and the upstream of the outbound conveying line 300, for storing finished product goods, and the automatic loading area 500 is arranged at the outbound end of the outbound conveying line 300.The intelligent finished product warehouse system further includes a separate outbound buffer area 400, the inlet end of the outbound buffer area 400 is connected with the outbound end of the outbound conveying line 300, and the outlet end is provided with the manual loading area 600.The outbound buffer area 400 is arranged along a straight line and is composed of a plurality of conveying sections, and the total effective buffer capacity of the conveying sections is pre-configured to be not less than the amount of goods of a standard loading unit, usually the amount of goods of a whole vehicle.

[0034] The above scheme enables the goods taken out from the finished product storage rack 100 to be temporarily stored in the huge outbound buffer area 400 first instead of being directly sent to the loading area full of uncertainties, so that the intelligent finished product warehouse system can obtain sufficient buffer time and wait for the final vehicle information confirmation, such as learning whether the vehicle meets the automatic loading conditions, and then transfer the finished product goods to the automatic loading area 500 or the manual loading area 600.The setting of the outbound buffer area 400 also enables the intelligent finished product warehouse system to handle the front-end exceptions more calmly and completely avoid systematic congestion caused by insufficient buffer.

[0035] In some embodiments, the outlet end of the outbound buffer area 400 is provided with a path control mechanism (not shown in the figure), which can realize the direction of goods transmission by motor forward and reverse rotation, or electric switch, push rod type flow divider or other path switching devices known in the art.It can receive the loading information instructions from the upper warehouse management system, such as license plate recognition results, vehicle models or manual switching commands, and dynamically guide the goods in the outbound buffer area 400 to the automatic loading area 500 or the manual loading area 600, which can be understood as the core executive component for flexible and rapid switching between automatic and manual loading modes.

[0036] In some embodiments, please refer to Figure 1 To realize huge buffer capacity in limited straight line length, at least part of the plurality of conveying sections of the outbound buffer area 400 is configured as a reinforced conveying section 401.The reinforced conveying section 401 is designed to simultaneously accommodate and convey multiple goods units, such as two 1-ton pallets.

[0037] In some embodiments, the standard loading unit is configured to carry 33-35 tons of goods, preferably 34 tons, which is the capacity of one truck. The outbound buffer area 400 can be configured by 18 conveyor segments connected in series, as shown in Figure 1 The number of conveyor segments is a preferred embodiment that has been calculated and verified to balance the buffer requirements and the site constraints. Optionally, each conveyor segment can be about 4 meters long, which is not limited here.

[0038] In some embodiments, the weight of a goods unit is 1 ton, and all 18 conveyor segments of the outbound buffer area 400 are configured as the reinforced conveyor segment 401 described above, each of which can simultaneously accommodate and transport two goods units. To achieve this function, the drive motor 402 of the reinforced conveyor segment 401, the frequency converter for its power supply and control, and the electrical control box containing the two, need to be upgraded, as shown in Figure 2 The power and specifications are configured to be able to drive at least two tons of load, i.e., the load of at least two goods units.

[0039] In some embodiments, the reinforced conveyor segment 401 is preferably a chain conveyor, which has the characteristics of strong carrying capacity and stable and reliable operation, and is particularly suitable for conveying heavy ton bags.

[0040] In some embodiments, as shown in Figure 2 At least one conveyor segment of the outbound buffer area 400 is additionally provided with a photoelectric sensor 403 for detecting the state and position of the goods. One specific embodiment is that the number of photoelectric sensors 403 is two, and the two photoelectric sensors 403 can be located on the left and right of the reinforced conveyor segment 401. Specifically, each photoelectric sensor 403 can be configured as a transmissive photoelectric sensor, including a transmitter and a receiver, as shown in Figure 2 Since in some embodiments, the reinforced conveyor segment 401 can carry two goods units, the addition of two photoelectric sensors 403 can determine the relative position and presence of the two goods units (such as two ton bags or pallets) on the conveyor segment, which is the basis for the automatic operation of the system.

[0041] In some embodiments, please refer to Figure 1 The inbound conveying line 200 is configured as a bidirectional inbound conveying line. It includes a first inbound line 210 and a second inbound line 220 that can operate independently at the same time. The inbound end of the first inbound line 210 is connected to the first side 100a of the finished product storage rack 100, and the inbound end of the second inbound line 220 is connected to the second side 100b of the finished product storage rack 100. This layout allows incoming materials to be received from two different directions of the warehouse at the same time, greatly improving the inbound throughput capacity and operational flexibility of the system.

[0042] In some embodiments, please continue to refer to Figure 1The finished product storage rack 100 comprises a high-position storage area 110 and a low-position storage area 120 arranged in parallel. The high-position storage area 110 refers to a high-bay warehouse accessed by a rack stacker, used for high-density long-term storage of goods; the low-position storage area 120 refers to a rack area with a lower height, accessed quickly by a shuttle or AGV, used for quick turnover and buffering of goods. The high-position storage area 110 and the low-position storage area 120 both extend along the direction from the first side 100a to the second side 100b, which can be understood as the depth direction of the warehouse. The extension direction of the outbound buffer area 400 can be consistent with the extension direction of the high-position storage area 110. The outbound buffer area 400 can be adjacent to the storage area with higher frequency of use in the high-position storage area 110 and the low-position storage area 120, that is, if the high-position storage area 110 is used more frequently, the outbound buffer area 400 can be arranged on the side of the high-position storage area 110 away from the low-position storage area 120; if the low-position storage area 120 is used more frequently, the outbound buffer area 400 can be arranged on the side of the low-position storage area 120 away from the high-position storage area 110. Such a layout structure is more compact, the logistics path is smooth, and the overall system layout is reasonable, further improving the space utilization rate.

[0043] In some embodiments, please continue to refer to Figure 1 The first warehouse-in line 210 or the second warehouse-in line 220 can be sequentially provided with a palletizing station 201, a weighing station 202, a paperboard feeding station 203, at least one rocker arm type film wrapping machine 204, and an outline detection station 205, 206, respectively. Before entering the warehouse, the goods can sequentially complete a series of automatic processing procedures such as palletizing, weighing, paperboard padding, film wrapping and fixing, outline visual detection, and information code scanning and binding, to ensure that only qualified goods can enter the rack storage.

[0044] As a summary, the intelligent finished product warehouse system with bidirectional warehouse-in and outbound buffer proposed in the present application has at least the following technical effects: 1. By providing a large-capacity linear outbound buffer area, the system provides a key buffer space, fundamentally avoiding system congestion caused by uncertainty at the loading end, and improving the stability and reliability of the outbound process. 2. By the path control mechanism, automatic and manual loading modes are switched without disturbance, the exception handling process is greatly simplified, and the overall loading efficiency is significantly improved. 3. By the bidirectional warehouse-in design, the warehouse-in capacity and flexibility of the system are improved, making it better adapt to the incoming material pressure during peak periods. 4. By the cooperation of the high-position storage area and the low-position storage area, and the reasonable layout of the outbound buffer area, an intelligent warehouse system with clear levels and efficient cooperation is constructed, and the overall operation efficiency is greatly improved.

[0045] Obviously, the above embodiments of the present application are merely examples for clear illustration of the present application, and are not intended to limit the implementation modes of the present application. Based on the above description, other different forms of changes or variations can also be made by those skilled in the art. Here, all the implementation modes are not required or can not be exhausted. Any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
