Oscillating Satellite Roller Feeding Device for Packaging Machines

The patent extracts and eliminates the connecting rod mechanism and counterweight from the system. Instead of using mechanical linkages to achieve cyclic oscillation of the satellite roller, the invention uses a motor directly mounted on the drive roller axis that can be programmed to oscillate the satellite roller cyclically. This extraction of the complex mechanical linkage resolves the contradiction by maintaining the oscillation function while dramatically reducing device complexity.

The patent replaces the mechanical linkage system (connecting rod and counterweight) with an electrical control system. A motor with programmable control replaces the mechanical oscillation mechanism, allowing the satellite roller to oscillate cyclically without the complexity of mechanical linkages. This substitution resolves the contradiction by maintaining the desired oscillation motion while eliminating the complex mechanical structure.

The patent removes the counterweight and connecting rod mechanism from the system. By eliminating these heavy components, the overall inertia of the feed station assembly is significantly reduced. The satellite roller is controlled directly by a motor mounted on the drive roller axis, which provides control functionality without adding the excessive inertia associated with counterweights and mechanical linkages.

The patent replaces the heavy mechanical control system (counterweight and connecting rods) with a lightweight electrical control system. A motor with programmable control replaces the mechanical oscillation mechanism, providing the same control functionality for the satellite roller while dramatically reducing the weight and inertia of the moving parts. This substitution resolves the contradiction between control capability and inertia.

The patent replaces the multi-component mechanical oscillation system with a direct motor-driven system. The motor is mounted on the drive roller axis and directly controls the satellite roller oscillation, eliminating intermediate mechanical connections. This reduction in mechanical interfaces minimizes cumulative alignment errors and register losses, thereby improving the longitudinal and lateral registration precision between the feed station and the subsequent chopping unit.

The patent extracts and removes the connecting rod and counterweight mechanisms that introduce multiple mechanical interfaces. By eliminating these intermediate components, the system reduces the number of potential sources of misalignment and register loss. The direct motor-to-satellite-roller control path maintains oscillation functionality while improving registration precision.

The patent replaces the complex mechanical linkage system with an electrical control system. A motor with programmable control directly actuates the satellite roller, eliminating the connecting rod, counterweight, and other intermediate mechanical components. This substitution dramatically reduces wear and failure points, as electrical motors have fewer moving parts subject to mechanical wear. The cyclic control functionality is maintained through programmable motor control, improving reliability while preserving the desired oscillation motion.

The patent removes the connecting rod mechanism and counterweight from the system. By extracting these mechanical linkage components, the system eliminates the sources of mechanical wear and potential media jams. The satellite roller oscillation is achieved through direct motor control, which has no mechanical linkages to wear out or fail. This extraction of problematic mechanical components resolves the contradiction between cyclic control capability and component durability.
