Vibrating Conveyor

Abstract

The vibrating conveying device provided by the present invention can easily adjust the conveying state along the conveying path; the vibrating conveying device of the present invention has: a conveying body provided with a conveying path; a pair of driving leaf springs (11), (12) , which support the conveying body at the front and rear positions of the conveying direction (F) of the conveying path; The leaf spring is connected with the conveying body; a pair of piezoelectric driving bodies (D1), (D2) are respectively arranged at the front and rear positions of the conveying direction, and one end of the pair of piezoelectric driving bodies is respectively connected with a pair of connecting bodies; Components (Cn), (Cw) that connect the other ends of a pair of piezoelectric actuators to each other; a pair of plate springs (17) and (18) for anti-vibration that are front and rear in the conveying direction on the installation surface A pair of connecting bodies are respectively supported at the positions; and a spring angle adjustment mechanism (20) is configured to be able to adjust the inclination angle of the anti-vibration leaf spring on at least any one side of the front and rear of the conveying direction.

Description

technical field [0001] The present invention relates to a vibrating conveying device, in particular to a mechanism for adjusting the conveying state of conveyed objects. Background technique [0002] Conventionally, there is known a vibrating conveying device for supplying electronic components and the like to an inspection device and the like while being aligned on a conveying path in a manufacturing facility. In this case, since the processing speed of the conveyed object such as the inspection device arranged on the downstream side of the conveying path is constant, at the supply end of the conveying path of the vibrating conveying device, it is necessary to adjust the speed with the downstream side. The conveyed material is supplied at a speed corresponding to the processing speed of the supply target device. [0003] Here, if the supply speed of the conveyed object is lower than the processing speed of the supply target device, the processing efficiency of the entire m...

Problems solved by technology

Therefore, there is a problem that the conveying speed of the conveyed object cannot be adjusted sufficiently without changing the inclination angle of the anti-vibration leaf spring to a certain extent, but when the above-mentioned inclination angle is greatly changed, the vibration pattern becomes unstable

[0014] In addition, in this method, since the support form of the driving vibration system composed of the conveying body and the weight connected via the driving plate spring changes greatly in the conveying direction, it is necessary to properly set the conveyance of the entire conveying body. When balancing the state, such as the uniformity of the conveying speed on the entire conveying path or the variation of the conveying speed in the conveying direction, the balance of the front and rear anti-vibration leaf springs must be considered, so the actual adjustment work is difficult in most cases.

[0015] In addition, in the method of adjusting the inclination angle of the plate spring for anti-vibration as described above, although the posture or height of the transport body can be kept almost constant, it is unavoidable that the posture or height will be changed due to the installation or removal of bolts or screws. Minor deviations occur. Therefore, in order to cope with the situation that the accuracy required for the posture or height of the conveyed body has gradually increased with the miniaturization of the conveyed objects in recent years, it is impossible to omit the readjustment of the posture or height in the same way as the above method. complex work
