Vibratory conveying apparatus

Abstract

The invention provides a vibratory conveying apparatus. Via a simple structure, acting force imposed on an arranging face can be reduced and high frequency of vibration or high speed of transportation can be achieved. The vibratory conveying apparatus (10) is provided with a pair of anti-vibration springs (13a, 13b), a standard quality body (11), an upper-side quality body (12A), a lower-side quality body (12B), a pair of plate-shaped upper-side vibration springs (14a, 14b), a pair of plate-shaped lower-side vibration springs (15a, 15b) and in-phase vibration excitation mechanisms (16a, 16b). The standard quality body is supported by the anti-vibration springs in the front and back positions in the delivery direction (D). The upper-side quality body (12A) is arranged on the standard quality body. The lower-side quality body (12B) is arranged under the standard quality body. The plate-shaped upper-side vibration springs elastically connect the standard quality body and the upper-side quality body in the front and back positions in the delivery direction. The lower-side vibration springs elastically connect the standard quality body and the lower-side quality body in the front and back positions in the delivery direction. The in-phase vibration excitation mechanisms impose vibration excitation force between the standard quality body and the upper-side quality body, and between the standard quality body and the lower-side quality body, thereby generating in-phase vibration in the delivery direction. Via the in-phase vibration excitation mechanisms, the upper-side quality body and the lower-side quality body are allowed to vibrate in the vibration directions (BVs, BVt) which incline in upper and lower opposite sides.

Description

technical field [0001] The present invention relates to a vibrating conveying device, and more particularly to a conveying mechanism suitable for a conveying device that conveys components linearly. Background technique [0002] Usually, the vibrating conveying device is configured as follows: the conveying body is elastically supported on the pedestal via a leaf spring, and the conveying body is excited by an excitation mechanism such as an electromagnetic driver or a piezoelectric driver, so that the conveying body is directed obliquely upward. Vibration, thereby conveying objects such as parts along the conveying path formed on the conveying body. In recent years, more and more tiny electronic devices are used as transport objects. In addition, the demand for high-speed supply of such tiny transport objects is increasing. It is a device that transports objects at high speed while arranging them neatly.

Problems solved by technology

[0012] However, in the above-mentioned existing vibrating conveying device provided with the reaction counterweight, there is the following problem, that is, in order to make the center of gravity of the conveying body and the center of gravity of the reaction counterweight close to, or arrange on the same straight line, the structure changes. Complicated, which leads to an increase in the size of the device or an increase in manufacturing costs, and since the position of the center of gravity must be set extremely precisely, it is difficult to obtain sufficient effects at a manufacturing site where the type of conveyed object or the conveying speed is constantly changing

In particular, when the driving frequency is increased to enable high-speed transportation, even if there is only a slight deviation in the position of the center of gravity, the pitching motion or up-and-down motion will become severe, and an appropriate conveying state cannot be obtained, so it is difficult to achieve high frequency or high speed. delivery
