Oscillatory type part supplying device

Abstract

The invention provides an oscillatory type part supplying device with an oscillation feeder, which can enhance the part supplying capacity without increasing the number of exciting mechanisms. The device is provided with part conveying mechanisms (3) which make part conveying components (9) supported by leaf springs (8) equipped on the peripheral wall of oscillating discs (4) and the discharge ends of the oscillating discs (4) connected. The part conveying mechanisms further make the part conveying components (9) oscillated by exciting mechanisms of the oscillation feeder (2) so as to convey the parts (P) along the same direction as the oscillation feeder (2) conveys and at a greater speed than the speed of the oscillation feeder (2). Therefore, the part conveying mechanisms (3) achieve conveying the parts (P) arranged in layers to a subsequent process at a greater conveying speed than the speed of the oscillation feeder (2). The oscillatory type part supplying device is then enabled to have a larger part supplying capacity than a current oscillation feeder without adding any exciting mechanism.

Description

technical field [0001] The present invention relates to a vibration-type parts supply device provided with a vibration feeder. Background technique [0002] A general vibrating feeder used in a vibrating parts supply device includes: a vibrating plate with a spiral conveying path; an upper vibrating body on which the vibrating plate is installed; a lower part connected to the upper vibrating body by a plurality of inclined leaf springs vibrating body; and a vibrating mechanism that vibrates the two vibrating bodies, and the vibrating feeder imparts vibration to the vibrating plate through the upper vibrating body from the vibrating mechanism, so that the parts dropped into the vibrating plate are transported along the conveying path (for example , refer to Patent Document 1). [0003] The above-mentioned vibrating feeder usually has only one vibration mechanism, and the conveying direction is determined by the installation direction of the leaf spring connecting the upper v...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned vibrating feeder usually has only one vibration mechanism, and the conveying direction is determined by the installation direction of the leaf spring connecting the upper vibrating body and the lower vibrating body, so the conveying speed of parts cannot be changed at a part of the conveying path or feed parts in the opposite direction

Therefore, there is a problem that the degree of freedom of the transportation method is low, and it is not possible to efficiently supply parts according to conditions such as the type and arrangement posture of the parts put into the vibrating plate.

[0004] For example, since the maximum conveying speed is determined, it is not possible to increase the conveying speed according to conditions to achieve an increase in parts supply capacity

Moreover, since the conveying speed is constant throughout the conveying path, parts tend to stagnate on the conveying path, and in the case of distinguishing parts using sensors, etc., the parts are in a state of contact with each other in the distinguishing section on the conveying path. is transported, so the discrimination accuracy tends to drop

In addition, the conveying direction is fixed, so the parts discharged from the conveying path in the division, etc. are returned to the bottom of the vibrating plate, or have to be returned to the conveying path on the upstream side of more than one turn from the discharge position. Ability to supply parts is suppressed

Furthermore, there is a problem as follows: in the case where a chute (hereinafter referred to as a self-weight chute) is provided to allow the parts discharged from the discharge end of the vibrating plate to slide down by its own weight and be sent to the next process (hereinafter referred to as a self-weight chute), the Parts sometimes stagnate on the way, and if the chute connected to the discharge end of the vibrating plate is vibrated by a vibration mechanism different from that of the vibrating feeder, although the problem of stagnation of parts in the chute disappears, the parts supply device The overall structure becomes complicated, which leads to a substantial increase in cost
