Vibrating parts feeder

Abstract

A vibration part feeding apparatus is provided to easily generate vibration suitable for feeding parts by effectively preventing generation of vertical vibration resulting from horizontal vibration. A middle vibration body is connected to an upper vibration body for assembling a groove (a part feeding component) by means of a second plate spring (an elastic component for vertical vibration) facing towards a horizontal direction. The middle vibration body is connected to a base by means of a first plate spring (an elastic component for horizontal vibration) facing towards a vertical direction. When the groove is made to vibration with a natural vibration frequency Fh of the horizontal direction, the amplitude Vv of vertical vibration generated by the groove is over 6dB smaller than the amplitude Vh of the horizontal vibration generated by the groove. Accordingly, the amplitude of vertical vibration resulting from the horizontal vibration of the groove can be reduced, and the desired vibration suitable for parts moving can be easily achieved.

Description

technical field [0001] The present invention relates to a vibrating type component conveying device which vibrates a component conveying member by driving a vibrating mechanism to convey components. Background technique [0002] In the vibrating parts conveying device, there is one that can adjust the vibration in the horizontal direction and the vibration in the vertical direction of the parts conveying member for the purpose of applying the vibration most suitable for parts conveying to the parts conveying member. Structured compound vibration type parts conveying device (for example, refer to Patent Document 1.). [0003] As a component conveying device of the composite vibration type as described above, there is a component conveying device having the following structure: for example, as an embodiment of the present invention, figure 1 as well as figure 2 As shown in the linear feeder (feeder), a rectangular frame-shaped intermediate vibrating body 4 is arranged aroun...

[0010] However, in such a compound vibrating disk feeding device, if the natural frequency F of the disk in the horizontal rotation direction h Vibration amplitude V in the horizontal direction of vibration h , and the vibration amplitude V in the vertical direction v The difference is only about 1dB to 2dB, then it is the same as the case of the above-mentioned linear feeding device, when the frequency F which is the natural vibration frequency of the horizontal rotation direction of the disk h When the first vibrating mechanism is driven at a frequency close to it, the disk will generate a vertical vibration with a large amplitude. It becomes difficult to adjust the direction of vibration, and it is often impossible to apply the vibration most suitable for parts transportation to the disk.
