Abstract
A bowl having a spiral track on its own inner circumference is fixed fast on a vibrating plate. To this vibrating plate is given the obliquely rotational vibration composed of the horizontal rotation and the up-and-down motion, and the elliptical vibration as well, with the use of a driving mechanism driven by a motor jointly with an up-and-down mechanism. These vibrations may be made now linear now non-linear dependingly on the form of the cam attached to the shaft of the motor.
Claims5
A vibratory bowl feeder, comprising:
- a base;
- a bowl for holding articles to be fed;
- a vibratory plate fastened to the bowl;
- first means for securing the vibratory plate to the base in a manner that the bowl is rotatable and will move up and down with respect to the base when rotated;
- a rotatable shaft;
- an eccentric plate secured to the shaft;
- motor means for rotating the shaft;
- and
- second means for converting rotational motion of the shaft to oscillatory rotation of the bowl, said second means including a link arm of adjustable length, one end of the link arm being pivotally secured to the eccentric plate and another end of the link arm being pivotally secured to the vibratory plate.
