Description

TECHNICAL FIELD

[0001] The utility model relates to the field of logistics conveying technology, especially to a can accumulate and control package conveying line. BACKGROUND

[0002] In modern industrial production, automatic stacking machines and automatic loading machines are widely used in the handling and loading of various products, greatly improving production efficiency and reducing labor costs. However, the efficient operation of these devices is highly dependent on uniform material feeding. In actual production, material supply is often difficult to stabilize and balance, with continuous multiple packages appearing at times and no material supply for a long time. This instability of material supply poses many challenges to the normal operation of automatic stacking machines and automatic loading machines.

[0003] When the material feeding is uneven, the automatic stacking machine may not be able to process the excessive material that has poured in for a short time, leading to equipment failure, affecting production progress, and possibly causing damage to the equipment, increasing maintenance costs. On the other hand, long-term material shortages can cause the stacking machine to be idle and waiting, wasting equipment resources and severely restricting the improvement of production efficiency.

[0004] To solve the problem of uneven material feeding, existing control package mechanisms mainly use two control methods: multi-section belt type and gate type. The multi-section belt type control package mechanism controls the conveying frequency of material packages by frequently starting and stopping each section of the belt. However, this method has obvious limitations. First, the number of controlled packages is limited, usually one section of the belt can only accommodate one material package, which not only increases the cost of the equipment, but also frequently starts and stops the operation, causing a large impact on the key components of the equipment such as the motor and the belt, accelerating the wear and tear of the components, significantly reducing the service life of the equipment, and increasing the maintenance and replacement costs of the equipment.

[0005] The gate type control package mechanism controls the passage of material packages by moving the gate up and down. However, the time required for the gate to move up and down is relatively long, and for production equipment with short package spacing and high efficiency requirements, this method cannot meet the actual needs. In addition, the gate type control package mechanism cannot effectively control the situation of multiple packages, which can easily cause material accumulation or poor conveying, affecting the smooth progress of the entire production process.

[0006] In summary, the existing control package mechanism has many shortcomings in dealing with uneven material feeding, and cannot meet the requirements of industrial production for efficient and stable material conveying. Therefore, it is of great practical significance and application value to develop a new type of control package conveying line that can accumulate and control packages to solve the problems existing in the prior art.
