Description

Technical Field

[0001] The utility model relates to the technical field of batching systems, and particularly relates to a transition pushing and positioning mechanism of an automatic batching system. Background Art

[0002] In multiple industries such as pharmaceuticals, chemicals, and military industries, it is often necessary to batch multiple different types of granular materials or powder materials. After various materials are metered and proportioned, they are loaded into the same bucket for use in the production line. After several production processes, the batched materials can be made into the required intermediate raw materials or products.

[0003] Conventional methods for batching multiple materials usually adopt manual batching or a manual batching assistance method mainly based on semi-automatic batching by machines. The equipment used for batching is a metering feeder, and each type of material is equipped with a corresponding metering feeder. During batching, a measuring cup is grabbed by a human or a manipulator and placed on the metering feeder for material metering and feeding. After each material is fed, it is then poured into a bucket with a bag to form a mixed material containing multiple materials. The batched mixed material is then sent to the production line later to be made into the required intermediate raw materials or products.

[0004] The deficiencies of the above methods of manual or semi-automatic batching are low production efficiency; in addition, for some pharmaceutical or chemical materials, manual batching or manual-assisted batching will have an adverse impact on the health of the batching operators. Moreover, manual batching or manual-assisted batching also increases the labor cost.

[0005] To this end, our company has newly developed a multi-material automatic batching system that can achieve fully automatic batching to address the above deficiencies. The multi-material automatic batching system mainly includes a bucket automatic conveying line, a feeding and metering conveying line, and multiple feeding devices; after the combination of the bucket automatic conveying line and the feeding and metering conveying line, a closed bucket automatic circulation conveying system is formed. The feeding and metering conveying line adopts a chain-type conveying mechanism, on which there are successively arranged an empty bucket weighing station, multiple batching stations, and a full bucket weighing station at intervals, and a lifting weighing mechanism is arranged below the empty bucket weighing station, multiple batching stations, and the full bucket weighing station, and feeding devices are respectively configured above the positions of each batching station. In addition, a bucket bag placing station and a bucket bag taking station are also provided on the bucket automatic conveying line, which are respectively used for placing bags for empty buckets and taking bags after batching. During operation, the bucket conveys the bucket with an empty bag from the front of the bucket automatic conveying line to the empty bucket weighing station on the feeding and metering conveying line. The lifting weighing mechanism at this station first weighs and measures the empty bucket, and then it is successively sent to the subsequent batching stations to respectively perform batching of different types of materials. After completing the batching of several types of materials in sequence, the bucket is moved to the full bucket weighing station, and the lifting weighing mechanism at this station weighs and measures and reviews the total weight of the bucket after batching; after the weighing and metering review of the bucket is completed, it is conveyed from the feeding and metering conveying line to the rear of the bucket automatic conveying line, and successively reaches the bucket bag taking station and the bucket bag placing station of the bucket automatic conveying line; at the bucket bag taking station, the bucket bag taking manipulator takes away the bag filled with batching in the bucket; the bucket after taking away the bag is moved to the bucket bag placing station of the bucket automatic conveying line, and the bucket bag placing manipulator places an empty bag into the bucket. Subsequently, the bucket with the empty bag returns to the front of the bucket automatic conveying line, and then is conveyed to the empty bucket weighing station on the feeding and metering conveying line again. In this way, the automatic circulation batching of multiple materials is realized.

[0006] A key problem that the above multi-material automatic batching system needs to solve is that when the bucket is conveyed from the front of the bucket automatic conveying line to the empty bucket weighing station on the feeding and metering conveying line by relying on its moving inertia, due to possible changes in the inertial force of the bucket, it may cause the bucket to fail to be accurately positioned at the batching station, thereby reducing the reliability of the operation of the multi-material automatic batching system. Utility Model Content
