GRAPHICAL ANALYSIS OF PERFORMANCE OF A VIBRATORY BOWL FEEDER FOR FEEDING BUTTONS

A brief review of previous work on the mechanics of vibratory conveying is presented followed by a new theoretical analysis of vibratory feeding on a track which vibrates with simple harmonic motion and where a phase difference may exist between the parallel and normal components of the track motion. For a wide range of practical conditions, the theoretical predictions are found to agree closely with the results of experimental tests. These show that certain fundamental limitations exist in the performance of conventional feeder drives where the two components of track motion are in-phase. From further theoretical and experimental work, it is shown that under conditions where the appropriate phase difference exists between the two components of track motion, many practical advantages over conventional vibratory feeding are obtained. With a new design of vibratory bowl feeder drive based on the results of the work, significantly higher conveying velocities may be obtained under stable feeding conditions and, further, these high conveying velocities are virtually independent of the coefficient of friction between the component and the track. The results of the present work apply equally to the design of spiral elevators and in-line vibratory feeders.

Abstract The design and implementation of vibratory bowl feeders involves the analysis of the behavior of the parts as they are conveyed up the bowl track. This paper presents the results obtained in a series of experiments which study the effect of the vibration amplitude in the feeder on the dynamic orientations of a family of parts. The objective of the study is to investigate how complex parts behave in a vibratory bowl feeder and try to establish a relationship between the orientation of the parts and the vibration amplitude of the bowl feeder. The study consisted of experimenting with four types of connectors that were similar in shape but differ in proportions. By experimenting with a part family, we intend to establish and generalize in the near future a relationship between the tendency of the parts to fall in certain orientations, the amplitude of vibration in the feeder, and geometric features or mass properties. The acquired knowledge could then be incorporated in computer aided design programs, together with existing theory on feeder design, to specify orientation devices and operating parameters in the vibratory bowl feeder.
