電式パーツフィーダについて記載している。The piezoelectric element 2 expands in a positive half cycle and contracts in a negative half cycle by application of an AC voltage. Therefore, in the bimorph 4 to which the piezoelectric element 2 is attached, the piezoelectric element 2 is applied to each piezoelectric element 2. When the applied voltage is shifted by half a cycle, the cantilever type bimorph structure converts the expansion and contraction movement into a bending movement. That is, the carrier 6 is vibrated. Further, Japanese Patent Laid-Open No.
Japanese Patent Publication No. 214511 discloses that an elastic plate is horizontally arranged on a lower surface of a base having an opening, an end of the elastic plate is fixed, and a free end of one end of the elastic plate is fixed to the opening provided in the base. The portion of the connecting body connected to one end of the driving piece is inserted into the opening provided in the base, and the upper end of the connecting body is fixed to an appropriate position of the carrier provided above the base, and the position of the carrier is adjusted. A piezoelectric parts feeder characterized in that it is set as low as possible is described.

を高めることを本願考案の第二の課題とする。The piezoelectric parts feeder of the invention described in Japanese Patent Application Laid-Open No. 1-214511, which has been conventionally known, is suitable for lowering the position of the carrier as low as possible. Although, the elastic plate to which the piezoelectric element is attached is suitable for the elastic plate to vibrate vertically because the elastic plate is oriented in the horizontal direction,
A disadvantage arises in that vibration in the front-rear direction is difficult, and vibration of the portion of the connecting member connected to the elastic plate is not efficient. Resolving this is the first problem of the present invention. In addition, the inclination of the elastic plate to which the piezoelectric element is attached and the inclination of the connecting member connected to the elastic plate are appropriately changed, and at the same time, the connecting portion is changed by the length of the driving plate 13.
The flexural vibration of the reference vibration can be
Causing movement, thus increases the amplitude of the carrier body 16
And, as a result, the transport speed of the transported article 18
A second object of the present invention to be increased.

And the upper end of the connecting member 15 with the elastic plate is fixed to the downward projection on the back side of the carrier 16 and the upper end of the connecting member 15 connected to the elastic plate is
So as to slightly inclined rearward with respect to the moving direction, before
Β degree is formed based on the vertical line that is dropped from the carrier 16.
Having formed, with to the inclination of the connecting member 15 and the inclination of the drive plate 13 to the lower position as possible the position of the carrier taking advantage complexly, with inclination of the elastic plate to which the piezoelectric element is mounted that By appropriately changing the inclination of the connecting member 15 connected to the elastic plate, there is an effect that the transport body can be operated as efficiently as possible. Further, when an AC voltage generated from an AC power supply 19 is applied to the piezoelectric drive type transfer apparatus 11 of the present invention, the drive plate 1
By making the length of the connecting member 15 longer than the length of 3,
As a result, a bending vibration, which is a non-reference vibration, occurs, whereby the amplitude of the carrier 16 can be increased.
As a result, there is an effect that the conveying speed of the conveyed article 18 can be increased . Further, the piezoelectric drive type transfer device 11 of the present invention is based on
Bimorph 14 and connecting member between table 17 and carrier 16
15 is not set up in a straight line,
To reduce the distance between the base 17 and the carrier 16 by providing, when reducing the size of the conveying device 11 together
The center of gravity of the conveyed object 18 laden piezoelectric drive transfer device 11 has an effect that it is possible to increase the stability of the piezoelectric driven conveying device 11 for lowered downward.
