Description

Technical Field

[0001] This utility model relates to the field of automatic packaging technology for rolled materials, specifically an automatic material feeding and dispensing device for roll packaging. Background Technology

[0002] In automated production lines for rolled materials, the buffering, sorting, and feeding of completed rolls are key processes affecting the overall line cycle time and yield. Existing technologies mainly suffer from the following shortcomings: 1. Manual handling and forklift changing are still the mainstream methods. There is a lack of automated interface between the multi-layer coil material rack and the machine, resulting in frequent manual material changing, high labor intensity, and easy damage to the coil edges or surface contamination due to bumps and knocks.

[0003] Multi-layer material racks have large differences in layer height and roll diameter, which traditional three-axis or four-axis robots cannot directly grasp. They often need to be set up with a buffer station next to the machine for secondary positioning, resulting in large equipment footprint and slow cycle time.

[0004] The transfer path of the coil material from the material rack to the sorting station is long, and it is mostly unidirectional and single-roll conveying. When changing rolls, the machine must be stopped and waited, which reduces the overall line utilization rate.

[0005] After the material rack moves on the ground, it is difficult to accurately reset. The manual visual alignment error is large, and the "top deviation" phenomenon often occurs after lifting, which causes the center of the roll material to be inconsistent with the center of the machine, affecting the accuracy of subsequent automatic tape threading or adhesive application.

[0006] Therefore, the market urgently needs a compact device that can achieve "multi-layer material rack one-time buffer, automatic precision positioning, automatic material distribution, and automatic material feeding" to solve the above pain points. Summary of the Invention
