Rolling Drum Blister Feeder
The Rolling Drum Feeder functions as a specialized derivative of the vibratory feeding system. It incorporates a synchronously rotating drum positioned directly beneath the vibratory chute. During operation, solid doses first enter the machined pockets of the drum, travel along its rotation, and are subsequently released into the formed blister cavities.
Motion Profile & Structural Design:
● Continuous-Motion Integration: In continuous-motion blister packaging machines, the rolling drum rotates in constant synchrony with the continuous web index, retaining the product in the drum pocket until the exact point of release.
● Intermittent-Motion Adaptation: In intermittent machines, the rapid step-by-step indexing of the web can outpace the settling rate of standard feeding plates, potentially causing tablets to misalign or sustain damage. To resolve this, the drum system is specifically modified for intermittent dynamics.
● Dual-Speed Execution: For intermittent operation, the drum’s pockets are divided into discrete groups distributed at specific angles around the circumference. The roller operates on a dual-speed control system. This variable speed allows the feeding plate to guide capsules or tablets smoothly into the drum at an adapted rate, before accelerating to synchronize with the web index for the dispensing phase. The feeding system runs in continuous cycles based on this logic.
