Adaptable design of a flexible vibratory bowel-feeder

摘要

A novel vibratory bowel-feeder with decoupled mechanical structure and digital coupled controller was investigated, utilizing decoupled principles and product platform concepts. To realize the independent controlling and synthesizing of rotate vibration and rectilinear vibration, the uncoupled mechanical structure was designed and working principles of the vibration platform was analyzed. The dynamics model was set up, analyzed and calculated using analytic and numeric simulation software respectively. The work space of the ellipse vibration with relation to vibratory angle was put forward. A prototype vibratory bowel feeder for magnetic pieces was built based on the vibration platform. The results show that composite motion of the feeding parts is working in line by the fact that two control systems for both the magnitude and phase can be changed independently. The feeder can meet the request to high speed, low wom-out, low noise part feeding, as well as adaptation the best out demand of feeding series parts and parts with different material.
