Description

Technical Field

[0001] The present invention relates to the technical field of intelligent automatic batching workshops, and in particular to a workshop batching management system and method. Background Art

[0002] The technical bottleneck of the traditional batching system. There are two typical operation modes in the traditional batching room: Manual batching relies on manual comparison with paper lists, and ingredient data needs to be recorded manually, making electronic archiving and traceability difficult. This leads to high human error rates and inefficient data management. Although traditional automated batching equipment uses pneumatic valves or electric valves to achieve precise control of valve opening and closing through wired control system signals to meet process-level batching ratio requirements, it is limited by the physical constraints of wired connections and cannot obtain real-time remaining material demand data from the weighing module on the wireless mobile batching vehicle. As a result, the system can only be adapted to a single rail-type batching vehicle, resulting in common industry pain points such as high equipment cost, low production efficiency, bulky equipment and high maintenance complexity. Summary of the Invention

[0003] The invention discloses a workshop batching management system to solve technical problems such as low efficiency and low precision.

[0004] In order to solve the above technical problems, the present invention proposes the following optimization technical solutions: A workshop batching management system, comprising: A server, comprising a recipe management system and an unmanned batching vehicle scheduling system.

Several unmanned batching vehicles, each comprising an AGV, a weighing module, a beamforming module, a PLC, and an industrial control system. The industrial control system is used to obtain the recipe order. The AGV cooperates with the unmanned batching vehicle scheduling system to direct the unmanned batching vehicle to the wireless communication valve to obtain raw materials. The beamforming module is used to send signals to control the opening and closing of the wireless communication valve. The weighing module is used to weigh the weight in the barrel of the unmanned batching vehicle. The PLC is used to control the beamforming module to send signals based on the weight of the weighing module.

[0008] Furthermore, the radiation transmitting module includes a large valve radiation transmitting module and a small valve radiation transmitting module, the radiation receiving module includes a large valve radiation receiving module and a small valve radiation receiving module, and the opening and closing module includes a large valve and a small valve; When the unmanned batching vehicle moves to the bottom of the wireless communication valve, the large valve radiation transmitting module sends a signal, the large valve radiation receiving module receives the signal, and the PLC controls the large valve to open; When the weight in the weighing bucket of the weighing module is close to the required weight of the raw materials, the signal of the large valve transmitting module is disconnected, the PLC controls the large valve to close, the small valve transmitting module sends a signal, the small valve receiving module receives the signal, and the PLC controls the small valve to open; When the weight in the weighing bucket of the weighing module is equal to the required weight of the raw materials, the signal of the small valve to the transmitting module is disconnected, and the PLC controls the small valve to close.

[0009] Furthermore, the said beam transmitting module further comprises an anti-missing hopper beam transmitting module, the said beam receiving module further comprises an anti-missing hopper beam receiving module, and the said opening and closing module further comprises an anti-missing hopper; When the weight in the weighing bucket of the weighing module is equal to the required raw material weight, the anti-missing hopper shooting transmitting module sends a signal, the anti-missing hopper shooting receiving module receives the signal, and the PLC controls the anti-missing hopper to move below the valve body outlet.

[0010] Furthermore, the radiation transmitting module and the radiation receiving module are infrared radiation photoelectric switches or laser radiation photoelectric switches.

[0011] The present invention provides another technical solution: a workshop batching method, comprising the following steps: S1. Select or create a recipe order from the recipe management system of the server. The industrial control system of the unmanned batching vehicle obtains the recipe order from the server. The recipe order contains at least one raw material. S2.

[0013] Furthermore, it also includes S4: after all the raw materials in the recipe order are prepared, the server controls the unmanned batching vehicle to move to an initial position.
