本発明は、部品を振動により移送することが可能な部品供給装置に関する。   The present invention relates to a component supply apparatus capable of transferring components by vibration.

従来、部品に対して振動を与えることにより、部品を整列させるとともに、部品の供給を行う部品供給装置の一つとしてパーツフィーダ等(部品搬送装置)がよく知られている。このパーツフィーダは、部品に振動を与えることにより部品の姿勢を整え、次工程に供給することができる。   2. Description of the Related Art Conventionally, a parts feeder or the like (part transporting apparatus) is well known as one of parts supplying apparatuses that align parts by supplying vibration to the parts and supply the parts. This parts feeder can adjust the posture of the part by applying vibration to the part and supply it to the next process.

特許文献1には、振動式部品搬送装置の加振機構の設置個数を減らして、かつ、部品の搬送速度や搬送方向の設定の自由度を高めることができる振動式部品搬送装置について開示されている。   Patent Document 1 discloses a vibratory component transport device that can reduce the number of vibration mechanisms installed in the vibration component transport device and can increase the degree of freedom in setting the transport speed and transport direction of the component. Yes.

この特許文献1記載の振動式部品搬送装置においては、搬送路を設けた振動体を、直進フィーダの上部振動体に、上部振動体の振動方向に対して水平面内で平行な方向に向けて、垂直面内で等しい傾斜角度を持たせて配列した2枚の板ばねで支持することにより、上部振動体から板ばねを介して伝搬される振動を利用して、自身の加振機構を設けることなく、部品の搬送速度や搬送方向の設定に自由度を持たせて、振動体に設けた搬送路に沿って部品を搬送できるようにしている。   In the vibration type component conveying apparatus described in Patent Document 1, the vibrating body provided with the conveying path is directed to the upper vibrating body of the linear feeder in a direction parallel to the vibration direction of the upper vibrating body in a horizontal plane. Supporting with two leaf springs arranged at equal inclination angles in the vertical plane, providing its own excitation mechanism using the vibration propagated from the upper vibrator through the leaf spring In addition, the degree of freedom in setting the conveying speed and conveying direction of the parts is given, and the parts can be conveyed along the conveying path provided in the vibrating body.

この特許文献2記載のリターンシュート付直進フィーダにおいては、従来の直進フィーダの駆動部取付ベースに固定された側板が前進運動用板バネにより発生する運動カウンターを利用し後進用板バネを動かす事により一台の直進フィーダで整送される部品が一つの駆動部で前後方向同時に送ることができるものである。
特開2005−35790号公報 実開平6−53534号公報
In the rectilinear feeder with a return chute described in Patent Document 2, the side plate fixed to the drive unit mounting base of the conventional rectilinear feeder uses a motion counter generated by the forward motion leaf spring to move the backward leaf spring. Parts that are fed by one linear feeder can be fed simultaneously in the front-rear direction by one drive unit.

しかしながら、特許文献1記載の振動式部品搬送装置および特許文献2記載のリターンシュート付直進フィーダのいずれにおいても、支持板ばねを傾斜させる必要があるため、トラフが前後方向に揺れるピッチング現象を生じた場合、搬送物が不安定となる。また、鉛直方向の振幅が、振動数・ばね強度・トラフ重量・重量バランス等により容易に変化し、任意の振幅を得ることは困難である。   However, in both the vibratory component conveying device described in Patent Document 1 and the linear feeder with return chute described in Patent Document 2, it is necessary to incline the support plate spring, which causes a pitching phenomenon in which the trough swings in the front-rear direction. In this case, the conveyed product becomes unstable. Further, the amplitude in the vertical direction easily changes depending on the frequency, spring strength, trough weight, weight balance, etc., and it is difficult to obtain an arbitrary amplitude.

本発明の目的は、容易に任意の振幅を得ることができるとともに、安定した部品の搬送を実現することができる部品供給装置を提供することである。   The objective of this invention is providing the components supply apparatus which can implement | achieve arbitrary amplitude easily and can implement | achieve the stable conveyance of components.

Further, a horizontal upward force F360a is applied from the horizontal transmission member 360a to the microcomponent 800 at the position of the microcomponent 800a via the third transport member 350. The micro component 800 at the position of the micro component 800a is transferred to the position of the micro component 800b by applying the resultant force of the forces F360a and F360b, that is, the force F800.

同様に、微小部品800bの位置にある微小部品800には、鉛直方向伝達部材360bから第3の搬送部材350を介して鉛直方向の力F361bが与えられる。また、微小部品800bの位置にある微小部品800には、水平方向伝達部材360aから第3の搬送部材350を介して水平上方向の力F361aが与えられる。微小部品800bの位置にある微小部品800は、力F361aおよびF361bの合力、すなわち、力F801が加えられ、微小部品800cの位置に搬送される。   Similarly, a vertical force F361b is applied from the vertical transmission member 360b to the microcomponent 800 at the position of the microcomponent 800b via the third conveying member 350. In addition, a horizontal upward force F361a is applied from the horizontal transmission member 360a to the microcomponent 800 at the position of the microcomponent 800b via the third transport member 350. The micro component 800 at the position of the micro component 800b is applied with the resultant force of the forces F361a and F361b, that is, the force F801, and is conveyed to the position of the micro component 800c.

以上のように、第3搬送部材350における微小部品800は、微小部品800aの位置から微小部品800bの位置に移送され、微小部品800bの位置から微小部品800cの位置に移送される。   As described above, the micro component 800 in the third conveying member 350 is transferred from the position of the micro component 800a to the position of the micro component 800b, and is transferred from the position of the micro component 800b to the position of the micro component 800c.

以上の構成により、第3搬送部材350に対して水平方向伝達部材360aから水平方向の振動(力F360a)、鉛直方向伝達部材360bから鉛直方向の振動(力F360b)が安定して供給されるので、第3搬送部材350を安定して振動させることができる。すなわち、リニア型パーツフィーダ300において、ピッチング現象が発生した場合でも、微小部品800を安定して搬送することができる。さらに、振動数、ばね定数等を容易に変更することができ、任意の振幅を得ることが容易となる。   With the above configuration, horizontal vibration (force F360a) is stably supplied from the horizontal transmission member 360a to the third transport member 350, and vertical vibration (force F360b) is stably supplied from the vertical transmission member 360b. The third conveying member 350 can be stably vibrated. That is, even when a pitching phenomenon occurs in the linear part feeder 300, the micropart 800 can be stably conveyed. Furthermore, it is possible to easily change the vibration frequency, the spring constant, etc., and to easily obtain an arbitrary amplitude.

さらに、水平方向伝達部材360aを介して圧電式振動部303から第3搬送部材350に水平方向の振動(力F360a)を確実に与えることができ、鉛直方向伝達部材360bを介して錘部302から第3搬送部材350に鉛直方向の振動(力F360b)を確実に与えることができる。   Furthermore, the horizontal vibration (force F360a) can be reliably applied to the third transport member 350 from the piezoelectric vibrating portion 303 via the horizontal transmission member 360a, and from the weight portion 302 via the vertical transmission member 360b. The vibration (force F360b) in the vertical direction can be reliably applied to the third transport member 350.
