Description of the Related Art The first problem associated with the above-described conventional piezoelectric drive type transfer device is that the transfer speed of the transfer component 8 is not high enough to meet the customer's request. In other words, a transport speed of about several hundreds / minute has been sufficient in the past, but with a significant increase in the assembling capacity of electronic equipment assembly lines in recent years, a transport speed of more than 1000 pieces / minute is required for a piezoelectric drive type transport device. Although it was reached, it is not possible to respond to this. The second problem is that the transport speed fluctuates greatly due to changes in the weight of the transport body including the transport component 8 with time. That is, it is necessary to adjust the power supply to the vibrating body 1 because a constant transport speed cannot always be obtained regardless of the weight of the transport body including the transport component 8.

面に対し５５゜〜７５°とすることである。The base 6 supports the carrier 5 via the vibrator 1 and the connecting member 4, and one end of the vibrator 1 is fixed to the base 6. However, in the present invention, the above-mentioned fixing is performed by inclining and standing the vibrating body 1 with an inclination angle of 55 ° to 75 ° with respect to the plane of the base 6. Conventionally, the tilt angle of the vibrator 1 is 45 ° or 3
It was 0 ° or less, and it was judged that it is difficult to solve the problems of the conventional technique under such an inclination angle, no matter how the other elements are changed. Therefore, in the present invention, one of the conditions for pursuing the possibility of solving the above-mentioned problem is added by changing the inclination angle of the vibrating body in the opposite direction to a very large direction and combining with elements other than the inclination angle of the vibrating body. The tilt angle of the vibrating body 1 is set to 55 ° to 75 ° with respect to the plane of the base 6.

一つである。The other end of the vibrating body 1 is fixed to one end of the connecting member. Here, the fixing of the other end of the vibrating body 1 and one end of the connecting member 4 has heretofore been made to be on the same straight line as the longitudinal direction of the vibrating body 1. However, in the present invention, the fixing is performed not on the same straight line but on the non-straight line in the longitudinal direction of the vibrating body 1. The non-linear fixation is one of the essential components of the present invention, and one of the important conditions for solving the problems of the prior art.

Here, the connecting member 4 used in the present invention is made thicker than the conventional one to increase the bending rigidity in order to narrow the change of the transfer speed due to the weight change of the transfer body 5 including the transfer component 8. That is. As an example, outer diameter 150
In the bowl feeder of mm, the thickness of the connecting member 4 is 1.2 times or more thicker than the conventional one, and the bending rigidity is 1.5 times or more higher.

５ｍｍ／ｓｅｃ以上を得ている。The other end of the connecting member 4 is fixed to the lower surface of the carrier. However, the fixing is performed by adjusting the inclination angle to the lower surface of the carrier 5 to be vertical or nearly vertical, which is one of the essential components of the present invention. Here, the angle of inclination close to vertical means an angle within 10 ° with respect to a vertical line from the lower surface of the carrier 5. The reason why the connection member 4 is fixed to the lower surface of the carrier 5 is to change the amplitude ratio in the vertical and horizontal directions of the vibration amplitude of the carrier 5 obliquely upward. That is, the ratio of the vibration amplitude in the vertical direction to that in the horizontal direction is conventionally 1: 4 or in the vicinity thereof, but no matter how the combination with other elements is changed, the ratio greatly increases the conveyance speed of the bottom conveyance component 8. Experiments have shown that this is difficult. Therefore, in the present invention, the vibration amplitude in the lateral direction of the carrier 5, which is an important factor of the transportation speed, is increased, that is, the vibration amplitude of the longitudinal vibration is
The problem was solved by increasing the ratio of the vibration amplitude in the lateral direction to a level higher than that of the conventional one, while keeping the size of the levitation in the air for a certain period of time. Specifically, the vibration amplitude ratio in the vertical and horizontal directions is appropriately increased within the range of 1: 5.5 to 7.8 depending on the weight of the carrier 5, and the thickness of the connecting member 4 is also increased. Due to the increase in the resonant frequency of the carrier itself, which is a side effect, the carrier speed is 2.2 times or more that of the conventional one.
5 mm / sec or more is obtained.

て搬送部品８の搬送をもたらすのである。When an AC voltage is applied to the piezoelectric element 2 which is one component of the vibrating body 1, the vibrating body 1 having a bimorph structure causes bending vibration as the piezoelectric element 2 expands and contracts. That is, when the AC voltage is applied, the piezoelectric element 2 expands in a positive half cycle and contracts in a negative half cycle, so that the attachment of the piezoelectric element 2 to the elastic plate 3 is expanded on one side and contracted on the other side. With such a configuration, the vibrating body 1 causes bending vibration having a cycle corresponding to the frequency of the AC voltage applied. This bending vibration is caused by positive inversion depending on the polarity of the applied AC voltage. If the vibrating body 1 is installed upright, the flexural vibration of the vibrating body 1 will be applied to the carrier body 5 to cause vibration in an obliquely upward direction so that the carrier component 8 is placed on the carrier body 5. If, for example, a pressing force is applied diagonally upward to the component 8, the transport component 8 is momentarily levitated in the air, and the transport body 5 slightly displaced at that moment is returned to its original position to transport the transport component 8. Will bring.

結果として搬送部品８は一方向のみに搬送される。The diagonal upward vibration of the carrier 5 is a combined vector of vibrations that are displaced in both the horizontal and vertical directions, and a habit force generated by the vibration acceleration on the carrier component 8 placed on the carrier 5. Relative slip and jump phenomena are brought about by the combined action with frictional force. The reason why vibration is required in the vertical direction of the carrier 5 is that the frictional force of the contact surface between the carrier 5 and the carrier component 8 is asymmetric. A vertical force (hereinafter, referred to as a normal force) acting on the conveying component 8 due to the vertical vibration changes with time, and the conveying component 8 becomes apparently heavy or light. By the way, since the frictional force is obtained by multiplying the normal force of the surface of the carrier 5 by the friction coefficient, if the vibration direction and phase of the carrier 5 are appropriately selected, the friction of different magnitudes in the forward and return paths of the vibration is generated. Is obtained, and as a result, the conveying component 8 is conveyed in only one direction.
