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.

hAlso there is boundary in little this respect, but owing to making its increase this respect not have boundary, therefore can be easy to adjust.
And expectation will be coiled the eigentone F of 21 horizontal rotatio direction
h, and the eigentone F of vertical direction
vBe adjusted to, constituting mutually between the value of the integral multiple below 5 separately is the relation of prime number.Because the integral multiple of eigentone becomes the eigentone with mode of vibration different with this eigentone, therefore if the horizontal rotatio direction of dish 21 and the eigentone F of vertical direction
h, F
vIntegral multiple become identical or close value, the amplitude of the vibration of the vertical direction that then causes because of the vibration of horizontal rotatio direction can increase.Here, the reason that the multiple value of this integral multiple is set at below 5 is, if this multiple value is not limited, then is difficult to set eigentone F separately
h, F
v, and if than eigentone F
h, F
v5 times big, then the vibration amplitude under this mode of vibration diminishes, and then diminishes to coiling 21 influence.
In addition, though it is more little good more to be preferably the vibration amplitude of the vertical direction that causes because of the vibration of coiling 21 horizontal rotatio direction, if this and will coil the eigentone F of 21 vertical direction
vSet too muchly, the rigidity that then has a vertical direction improves and makes the possibility that can't be caused the vibration of vertical direction by second exciting agency 28.Because the vibration amplitude of the vertical direction of expectation is about tens of μ m, therefore can be with the eigentone F of vertical direction
vBe adjusted to, make the amplitude of vibration of the vertical direction that vibration because of water article hand of rotation causes for several μ m～tens μ m about.
And; Since in this second embodiment with whirling vibration with leaf spring 25 be fixed in the same horizon that coils 21 vertical direction line of centers O quadrature on fixed position, 2 place; Therefore whirling vibration can not influence the displacement of vertical direction with the distortion of the horizontal rotatio direction of leaf spring 25, can suppress the vibration of the vertical direction that the vibration because of horizontal rotatio direction produces more effectively.
As stated; Because also the oscillatory type straightaway feedway with first embodiment is identical for the oscillatory type disc type feedway of this second embodiment; Can suppress the vibration of the vertical direction that the vibration because of horizontal rotatio direction produces effectively; Therefore when the vibration of the vibration of adjusting horizontal rotatio direction respectively and vertical direction; Can be adjusted to the vibration that makes horizontal rotatio direction influences the vibration of vertical direction hardly, can be easy to apply the vibration that is suitable for the expectation that parts carry to coiling 21.
Though in above-mentioned each embodiment; First leaf spring of vibrating mass in the middle of linking and pedestal is used elastomeric element with elastomeric element, second leaf spring that will link top vibrating mass and middle vibrating mass as vertical shake as horizontal vibration; But also can be in contrast, constituting first leaf spring becomes vertical shake and becomes horizontal vibration with elastomeric element, second leaf spring and use elastomeric element.And, though dispose a leaf spring throughout respectively, also can be with 2 overlapping uses of above leaf spring.And,, also can constitute and be arranged on more than 2 places though the leaf spring that leaf spring that horizontal vibration is used and vertical shake are used is separately positioned on 4 places.
And then, though in each embodiment, leaf spring is used elastomeric element as horizontal vibration with elastomeric element and vertical shake, also can use the elastomeric element beyond the leaf spring certainly.And, though will be used as each exciting agency, be not limited thereto by the mechanism that electromagnet and movable core constitute, get final product so long as can produce the actuator of same disturbance force.
