Description

Description: TECHNICAL FIELD The present invention relates to a device for vibrating a sieve, a net, or the like to sort articles, or a device for vibrating a film body to convey articles, and other articles. It can also be applied to a device for mixing, filling, dehydrating, demudging, removing adhered substances, etc.

(Prior Art) In many conventional sieve screen vibrating devices, the rotary motion of a motor or the like is converted into vibration by a mechanism such as a crank or an eccentric cam to vibrate the entire screen. Further, the conventional sieve mesh vibrating device has a complicated structure, and many of them can only vibrate in a single cycle.

Therefore, in the conventional sieve mesh vibrating device, the occurrence of clogging in a specific portion of the sieve mesh is reduced. Further, since the vibration condition is only a single vibration, the work efficiency is not so good, and it is impossible to finely change the vibration condition according to the article to be handled.

Further, in the conventional screen-mesh vibrating device, since the vibrating part of the screen and the like and the part of the motor that gives vibration are mechanically connected to each other, noises and vibrations exerted on the surroundings during the work are not small.

Further, a vibration generator for rotating a magnet to periodically attract and repel is disclosed in JP-A-48-84621 and JP-B-38-15738. However,
It is excited by the force of a magnet, but the point of action of that force is fixed, and the vibration of the vibrating body was simple and one-dimensional. It is a film or net that cannot generate two-dimensional or three-dimensional vibration in which the vibration and amplitude change freely in a two-dimensional manner by giving an exciting force with a different cycle and amplitude depending on the location. there were.
