<P>PROBLEM TO BE SOLVED: To enhance stability of conveyance and to suppress propagation of vibration to an external part, in a vibration type linear motion feeder linearly conveying a material to be conveyed. <P>SOLUTION: A vibration adding mechanism 5, in which an electromagnet 10 and a movable iron core 11 are opposed to each other in the vertical direction, is formed between an upper vibration body 2 to which a trough 1 is attached and a weight 9 connected to the upper vibration body 2 by a second leaf spring 12. A mass of an upper vibration system comprising the trough 1, the upper vibration body 2 and the movable iron core 11 is made smaller than the mass of a lower vibration system comprising the weight 9 and the electromagnet 10, and thus an amplitude amount of the trough 1 is made large and also a material to be conveyed having light weight can be stably conveyed. The upper vibration body 2 is supported by first leaf springs 4a and 4b having rigidity lower than that of the second leaf spring 12 and a coil spring 6 to form a two step vibration control structure, and thus propagation of vibration to an external part can be suppressed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
