Description

振動式部品搬送装置Vibrating parts conveyor
 本発明は、直線状の搬送路を有する部品搬送部材を振動させて、その搬送路上の部品を搬送する振動式部品搬送装置に関する。 The present invention relates to a vibration type component conveying apparatus that vibrates a component conveying member having a linear conveying path and conveys components on the conveying path.
 電子チップ部品等の部品を振動により搬送しながら整列させて(部品の姿勢を揃えて)次工程に供給する装置として、部品を直線状の搬送路に沿って搬送するシュートを有し、部品供給スピードを調整しやすい振動式直進フィーダの上流側に、螺旋状の搬送路が形成されたボウルを有し、部品を多く貯蔵できる振動式ボウルフィーダを接続した振動式部品搬送装置がよく使用される。 As a device that aligns parts such as electronic chip parts while conveying them by vibration (aligns the posture of the parts) and supplies them to the next process, it has a chute that conveys the parts along a straight conveyance path, and supplies parts A vibratory parts conveying device that has a bowl with a spiral conveying path on the upstream side of a vibratory linear feeder that is easy to adjust the speed and is connected to a vibratory bowl feeder that can store many parts is often used. .
 上記のようにボウルフィーダと直進フィーダを接続した振動式部品搬送装置では、一般に、両フィーダの振動方向、振動周波数および振幅が異なるため、ボウルフィーダの搬送路から直進フィーダの搬送路への部品受け渡し部で搬送路間に隙間を設ける必要があり、この隙間で部品の詰まりや引っ掛かりが発生しやすい。そこで、通常は、部品受け渡し部でボウルフィーダの搬送路よりも直進フィーダの搬送路を低くして、部品がスムーズに乗り移るようにしている。しかし、このように部品受け渡し部の搬送路間に落差を設けた場合は、ボウルフィーダで部品を整列させていても、部品が直進フィーダに乗り移ったときの衝撃で姿勢を変えたり、部品どうしが重なりあったりすることがある。 As described above, in a vibratory component conveying device in which a bowl feeder and a straight feeder are connected, the vibration direction, vibration frequency and amplitude of both feeders are generally different, so parts are transferred from the conveying path of the bowl feeder to the conveying path of the straight feeder. It is necessary to provide a gap between the conveying paths at the part, and the clogging and catching of parts are likely to occur in this gap. In view of this, normally, the parts transfer section is set so that the conveying path of the linear feeder is lower than the conveying path of the bowl feeder so that the parts can be transferred smoothly. However, when a drop is provided between the conveyance paths of the parts delivery section in this way, even if the parts are aligned by the bowl feeder, the posture is changed by the impact when the parts move to the linear feeder, or the parts are There may be overlap.
 これに対して、下記特許文献1では、振動式直進フィーダの搬送路の入口部をR溝とすることにより、部品の挙動の自由度を大きくして、重なりあったり二列に並んだりした状態の部品を一列一層に整列しやすくすることが提案されている。 On the other hand, in Patent Document 1 described below, the entrance portion of the conveying path of the vibration type linear feeder is an R groove, which increases the degree of freedom of the behavior of the parts, and is overlapped or arranged in two rows. It has been proposed to make it easier to align the parts in a row.

 ところで、一般的な振動式直進フィーダでは、そのシュート等の部品搬送部材の搬送路の途中に、上流側から搬送されてきた部品を搬送しながら、部品の姿勢を矯正したり姿勢不良の部品を排除したりする整列搬送部が設けられていることが多い。その場合、搬送路の入口から整列搬送部までの部分を上記特許文献1に記載されているようにR溝として、部品を一列一層に整列させやすくしていても、図4(a)~(c)および図5(a)~(d)に基づいて以下に説明するように、R溝と整列搬送部の入口形状が異なることにより、その段差で部品が姿勢を変えたり重なりあったりしてしまうおそれがある。 By the way, in a general vibration type linear feeder, the posture of a component is corrected or the posture is poor while the component conveyed from the upstream side is conveyed in the middle of the conveyance path of a component conveying member such as a chute. In many cases, an aligning / conveying section that is excluded is provided. In that case, even if the part from the entrance of the transport path to the aligning and transporting portion is an R groove as described in Patent Document 1, the parts can be easily aligned in a single row, as shown in FIGS. As described below based on c) and FIGS. 5 (a) to (d), the shape of the inlet of the R-groove and the alignment transport unit is different, so that the parts may change posture or overlap at the step. There is a risk that.
 図4(a)~(c)および図5(a)は、直方体状の部品Pの整列搬送を行う振動式直進フィーダにおいて、シュート51の直線状の搬送路52の入口(図示省略)から整列搬送部53までの部分をR溝54とした例の要部を示す。その搬送路52の整列搬送部53は、長手方向が搬送方向に向く姿勢(以下、この姿勢を「良姿勢」と称する。)の部品Pだけを通過させ、姿勢不良(長手方向が搬送路幅方向に向く姿勢と長手方向が上を向いた姿勢)の部品Pは回収部55に落下させて搬送路52から排除するようになっている。一方、R溝54は、その底部(幅方向中央部)が整列搬送部53の送路面53aよりもわずかに高く形成されている。 4 (a) to 4 (c) and FIG. 5 (a) show the alignment from the entrance (not shown) of the linear conveying path 52 of the chute 51 in the vibration type linear feeder for aligning and conveying the rectangular parallelepiped parts P. The main part of the example which made the part to the conveyance part 53 the R groove | channel 54 is shown. The alignment conveyance unit 53 of the conveyance path 52 passes only parts P in a posture in which the longitudinal direction is in the conveyance direction (hereinafter, this posture is referred to as “good posture”), and the posture is poor (the longitudinal direction is the conveyance path width). The component P in a posture facing the direction and a posture in which the longitudinal direction faces upward is dropped on the collection unit 55 and removed from the conveyance path 52. On the other hand, the bottom of the R groove 54 (the center in the width direction) is formed slightly higher than the feeding path surface 53 a of the alignment transport unit 53.
 このシュート51のR溝54上の多くの部品Pは、R溝54の半円状の断面形状の作用により良姿勢で搬送され、その底部から整列搬送部53に乗り移るが、一部の部品Pは、R溝54の途中で姿勢を変えて良姿勢となったときに搬送路52の幅方向にふらつき、R溝54の底部よりも高い両側の斜面のうちのいずれか一方の斜面から整列搬送部53に乗り移る場合もある。 Many parts P on the R groove 54 of the chute 51 are conveyed in a good posture by the action of the semicircular cross-sectional shape of the R groove 54, and are transferred from the bottom part to the alignment conveyance part 53. Is shifted in the width direction of the transport path 52 when the posture is changed in the middle of the R-groove 54, and is aligned and transported from one of the slopes on both sides higher than the bottom of the R-groove 54. In some cases, the vehicle is transferred to the section 53.
 そして、R溝54の底部から整列搬送部53に乗り移った部品Pは、図5(b)に示すように、乗り移る際の落差が小さいため、良姿勢のまま搬送されていく。一方、R溝54の斜面から整列搬送部53に乗り移った部品Pは、乗り移る際の落差が大きいため、図5(c)に示すように、整列搬送部53の側壁53bに沿って立った姿勢になったり、図5(d)に示すように、長手方向が搬送路幅方向に向くように回転して姿勢不良となったりする。また、図示は省略するが、先行の部品Pの上に後続の部品Pが載ってしまうこともある。このように整列搬送部53に乗り移る際に姿勢を変えたり重なりあったりした部品Pは、回収部55に落下して排除されたり、さらに下流側の図示省略した部分で排除されたりして、直進フィーダの部品供給能力の低下を招く。 And, as shown in FIG. 5 (b), the component P that has been transferred from the bottom of the R groove 54 to the alignment transfer unit 53 is transferred in a good posture because of a small drop when changing. On the other hand, the part P that has been transferred from the inclined surface of the R groove 54 to the alignment conveyance unit 53 has a large drop at the time of transfer, and therefore, as shown in FIG. 5C, the posture standing along the side wall 53b of the alignment conveyance unit 53 Or, as shown in FIG. 5D, the posture may be poor due to rotation so that the longitudinal direction is directed to the conveyance path width direction. Although illustration is omitted, the succeeding part P may be placed on the preceding part P. The parts P that have changed their postures or overlapped when moving to the aligning / conveying section 53 in this manner are dropped into the collecting section 55 and removed, or further removed at a portion that is not shown on the downstream side. The feeder parts supply capacity will be reduced.
 そこで、本発明は、部品を直線的に搬送する部品搬送部材の搬送路の上流側にR溝を設けた振動式部品搬送装置において、部品供給能力の向上を図ることを課題とする。 Therefore, an object of the present invention is to improve the component supply capability in a vibration type component conveying apparatus in which an R groove is provided on the upstream side of a conveying path of a component conveying member that conveys components linearly.
 上記の課題を解決するため、本発明は、部品を直線状の搬送路に沿って搬送する部品搬送部材を備え、前記部品搬送部材の搬送路の上流側にR溝を設け、下流側にR溝と異なる断面形状の整列搬送部を設けた振動式部品搬送装置において、前記搬送路のR溝の出口から整列搬送部の入口までの部分を、部品搬送方向に沿って断面形状が前記R溝の形状から前記整列搬送部の入口形状に滑らかに変化する形状移行部とした。この構成によれば、搬送路のR溝の出口と整列搬送部の入口との間での急激な落差がなくなり、R溝で良姿勢となった部品が整列搬送部に乗り移るときに姿勢変化を生じにくくなるので、R溝の出口を整列搬送部の入口に直接接続した場合に比べて部品供給能力を向上させることができる。 In order to solve the above problems, the present invention includes a component conveying member that conveys a component along a linear conveying path, and an R groove is provided on the upstream side of the conveying path of the component conveying member, and the R is provided on the downstream side. In the vibration-type component conveying apparatus provided with the aligning and conveying unit having a different cross-sectional shape from the groove, the cross-sectional shape of the portion from the R-groove outlet of the conveying path to the inlet of the aligning and conveying unit along the component conveying direction The shape transition portion smoothly changes from the shape of the shape to the shape of the inlet of the alignment conveyance portion. According to this configuration, there is no sudden drop between the exit of the R-groove of the transport path and the entrance of the alignment transport unit, and the posture changes when a component in a good posture in the R-groove moves to the aligning transport unit. Since it becomes difficult to occur, the parts supply capability can be improved as compared with the case where the outlet of the R groove is directly connected to the inlet of the aligning and conveying unit.
 上記の構成において、前記搬送路の形状移行部の長さを、前記部品の長手方向寸法の5倍以上としたり、前記搬送路の形状移行部を、前記R溝の出口から整列搬送部の入口に向かって下向きに傾斜させたりすることにより、部品が形状移行部をスムーズに通過できるようになる。前記搬送路の形状移行部を傾斜させる場合の傾斜角度は2~5°とすることが好ましい。 In the above configuration, the length of the shape transition portion of the transport path is set to be five times or more the longitudinal dimension of the component, or the shape transition portion of the transport path is changed from the exit of the R groove to the entrance of the alignment transport portion. By tilting downward toward the center, the part can smoothly pass through the shape transition portion. The inclination angle when the shape transition portion of the conveyance path is inclined is preferably 2 to 5 °.
 また、前記搬送路のR溝と形状移行部とのつなぎ目を面取りすれば、R溝から形状移行部への部品の乗り移りもスムーズになる。 Also, if the joint between the R groove of the conveyance path and the shape transition portion is chamfered, the parts can be smoothly transferred from the R groove to the shape transition portion.
 本発明の振動式部品搬送装置は、上述したように、直線状の搬送路の上流側のR溝と下流側の整列搬送部との間に、部品搬送方向に沿って断面形状がR溝の形状から整列搬送部の入口形状に滑らかに変化する形状移行部を設けて、R溝の出口と整列搬送部の入口との間での急激な落差をなくしたものであるから、R溝で良姿勢となった部品が整列搬送部に乗り移るときに姿勢変化を生じにくく、部品供給能力の向上を図ることができる。 As described above, the vibration type component conveying apparatus of the present invention has an R groove having a cross-sectional shape along the component conveying direction between the upstream R groove and the downstream aligned conveying portion of the linear conveying path. Since a shape transition portion that smoothly changes from the shape to the inlet shape of the alignment conveyance portion is provided, and a sharp drop between the outlet of the R groove and the inlet of the alignment conveyance portion is eliminated, the R groove can be used. When the components in the posture are transferred to the aligning and conveying unit, the posture is hardly changed, and the component supply capability can be improved.

This vibrating component conveying apparatus performs aligned conveying of rectangular parallelepiped components P, and as shown in FIG. 1, includes a vibrating bowl feeder 1 and a vibrating linear feeder 11 connected to the downstream side thereof. ing. Then, by vibrating the bowl 2 of the bowl feeder 1, the component P put into the bottom of the bowl 2 is conveyed by the spiral conveying path 3, and the chute (component conveying member) 12 of the linear feeder 11 is discharged from the outlet. By delivering the part P to the entrance of the linear conveyance path 13 and vibrating the chute 12 of the linear feeder 11, the part P on the conveyance path 13 of the chute 12 is conveyed linearly and supplied to the next process. ing.
 前記ボウルフィーダ1は、公知の構成のものであり、部品Pを螺旋状の搬送路3で搬送しながら、一列一層となるように整列させてシュート12の搬送路13に供給している。一方、直進フィーダ11は、シュート12の搬送路13の入口部分にR溝14が設けられ、下流側に整列搬送部15が設けられている。 The bowl feeder 1 is of a known configuration, and the parts P are arranged in a single line while being fed by the spiral conveyance path 3 and supplied to the conveyance path 13 of the chute 12. On the other hand, the rectilinear feeder 11 is provided with an R groove 14 at the entrance portion of the conveyance path 13 of the chute 12 and an alignment conveyance unit 15 at the downstream side.
 そして、図2(a)~(c)および図3(a)に示すように、前記直進フィーダ11のシュート12の搬送路13は、R溝14の出口から整列搬送部15の入口までの部分が、部品搬送方向に沿って断面形状がR溝14の形状から整列搬送部15の入口形状に滑らかに変化する形状移行部16となっている。 2 (a) to 2 (c) and FIG. 3 (a), the conveyance path 13 of the chute 12 of the linear feeder 11 is a portion from the outlet of the R groove 14 to the inlet of the alignment conveyance section 15. However, the shape transition portion 16 whose cross-sectional shape smoothly changes from the shape of the R groove 14 to the inlet shape of the alignment conveyance portion 15 along the component conveyance direction.
 前記R溝14および整列搬送部15の構成は、前述の従来のものと同じである。すなわち、整列搬送部15は、送路面15aが15~20°上向きに傾いたL字形に形成されるとともに、良姿勢でL字形断面のコーナ部に沿って搬送される部品Pだけを通過させる狭幅部を有し、姿勢不良(長手方向が搬送路幅方向に向く姿勢と長手方向が上を向いた姿勢)の部品Pは回収部17に落下させて搬送路13から排除するようになっている。一方、R溝14は、その底部(幅方向中央部)が整列搬送部15の送路面15aよりもわずかに高く形成されている。 The configurations of the R groove 14 and the alignment transport unit 15 are the same as the conventional ones described above. In other words, the aligning / conveying section 15 is formed in an L shape in which the feeding path surface 15a is inclined upward by 15 to 20 °, and is narrow so as to allow only the parts P conveyed along the corner portion of the L-shaped cross section in a good posture. A part P having a width portion and having a poor posture (a posture in which the longitudinal direction faces the width direction of the conveyance path and a posture in which the longitudinal direction faces the top) is dropped on the collection unit 17 and removed from the conveyance path 13. Yes. On the other hand, the bottom of the R groove 14 (the center in the width direction) is formed slightly higher than the feeding path surface 15 a of the alignment transport unit 15.
 前記形状移行部16は、R溝14の出口から整列搬送部15の入口に向かって下向きに傾斜しており、その傾斜角度は2~5°に設定されている。また、形状移行部16の長さは、部品Pの長手方向寸法の5倍以上に設定されている(図2(a)~(c)および図3(a)~(d)では、説明上、実際よりも短く描いている)。そして、この形状移行部16とR溝14とのつなぎ目は、面取り加工が施されている。面取り加工方法としては、例えば、ラッピングフィルム研磨やショットピーニング等がある。 The shape transition portion 16 is inclined downward from the outlet of the R-groove 14 toward the inlet of the alignment conveyance portion 15, and the inclination angle is set to 2 to 5 °. The length of the shape transition portion 16 is set to be five times or more the longitudinal dimension of the component P (in FIGS. 2 (a) to (c) and FIGS. 3 (a) to 3 (d)) , Drawing shorter than actual). The joint between the shape transition portion 16 and the R groove 14 is chamfered. Examples of the chamfering method include lapping film polishing and shot peening.
 なお、実際にシュート12を製作する際には、R溝14および形状移行部16の部分と整列搬送部15の部分を別々の部品で形成して一体に接続することができる。その場合、上流側の部品は、搬送方向全長にR溝14を加工した後、下流側の部品を加工するのと同じ切削工具で下流側端からR溝14を削り取るように加工して、形状移行部16を形成するとよい。もちろん、上流側部品の上流側から切削加工して形状移行部16を形成することもできる。また、必ずしもこのようにシュート12を分割する必要はなく、1個の部材を加工して、R溝14、形状移行部16および整列搬送部15をそれぞれ形成するようにしてもよい。 It should be noted that when actually manufacturing the chute 12, the R groove 14 and the shape transition portion 16 and the alignment transport portion 15 can be formed by separate parts and connected together. In that case, after processing the R groove 14 in the entire length in the conveying direction, the upstream part is processed so that the R groove 14 is cut off from the downstream end with the same cutting tool that processes the downstream part. The transition part 16 may be formed. Of course, the shape transition part 16 can also be formed by cutting from the upstream side of the upstream part. In addition, the chute 12 does not necessarily need to be divided in this manner, and one member may be processed to form the R groove 14, the shape transition portion 16, and the alignment conveyance portion 15, respectively.
 次に、この振動式部品搬送装置での部品Pの流れについて説明する。ボウルフィーダ1のボウル2の底部に投入された部品Pは、螺旋状の搬送路3を搬送されていき、その出口から直進フィーダ11のシュート12の搬送路13入口部分に設けられたR溝14に乗り移る。シュート12のR溝14に乗り移った部品Pは、乗り移る際に一旦姿勢を変えたり重なりあったりしても、R溝14の半円状の断面形状の作用により再び一列一層で良姿勢となって搬送されていき、形状移行部16を通って整列搬送部15に送られる。 Next, the flow of the component P in this vibration type component conveying apparatus will be described. The part P thrown into the bottom of the bowl 2 of the bowl feeder 1 is transported through the spiral transport path 3, and an R groove 14 provided at the entrance of the transport path 13 of the chute 12 of the linear feeder 11 from its outlet. Change to. Even if the parts P that have been transferred to the R groove 14 of the chute 12 are once changed in posture or overlapped with each other, they are again in a good posture in one row due to the action of the semicircular cross-sectional shape of the R groove 14. It is conveyed and sent to the alignment conveyance unit 15 through the shape transition unit 16.
 このとき、多くの部品Pは、図3(a)~(d)に示すように、R溝14の底部から形状移行部16に入り、良姿勢のまま整列搬送部15の側壁15bに近づいていってスムーズに整列搬送部15に乗り移る。また、形状移行部16はその断面形状がR溝14から整列搬送部15まで滑らかに変化しているため、図示は省略するが、R溝14の底部よりも高い斜面から形状移行部16に入る部品Pも、ほとんどが姿勢を変えることなくスムーズに整列搬送部15に乗り移る。 At this time, as shown in FIGS. 3A to 3D, many parts P enter the shape transition portion 16 from the bottom of the R groove 14 and approach the side wall 15b of the alignment transport portion 15 while maintaining a good posture. Smoothly transfer to the alignment transport unit 15. Further, since the cross-sectional shape of the shape transition portion 16 smoothly changes from the R groove 14 to the alignment conveyance portion 15, illustration is omitted, but the shape transition portion 16 enters the shape transition portion 16 from a slope higher than the bottom of the R groove 14. Most of the parts P smoothly transfer to the alignment conveyance unit 15 without changing the posture.
 そして、良姿勢のまま整列搬送部15に乗り移った部品Pは、整列搬送部15のL字形断面のコーナ部に沿って狭幅部を通過して下流側へ搬送されていき、シュート12の搬送路13の出口から次工程へ供給される。なお、整列搬送部15に乗り移ったときに姿勢不良となる部品Pは少ないが、その姿勢不良の部品Pは回収部17に落下してボウルフィーダ1のボウル2に戻される。 Then, the parts P transferred to the aligning and conveying unit 15 in a good posture pass through the narrow portion along the corner portion of the L-shaped cross section of the aligning and conveying unit 15 and are conveyed downstream to convey the chute 12. It is supplied to the next process from the exit of the path 13. In addition, although there are few parts P which become a posture defect when it transfers to the alignment conveyance part 15, the parts P with the attitude defect fall to the collection | recovery part 17, and are returned to the bowl 2 of the bowl feeder 1. FIG.
 この振動式部品搬送装置は、上述したように、直進フィーダ11のシュート12の搬送路13入口部分に設けたR溝14で、ボウルフィーダ1から受け取った部品Pを一列一層で良姿勢となるように整列させ、R溝14で整列させた部品を形状移行部16を介して良姿勢のまま整列搬送部15へ送り込めるようにしたので、R溝の出口を整列搬送部の入口に直接接続した場合に比べて、整列搬送部15で排除される部品Pが少なく、部品供給能力の向上が図れる。 As described above, the vibration type component conveying apparatus is configured so that the components P received from the bowl feeder 1 are in a good posture in a single row with the R groove 14 provided in the inlet portion of the conveying path 13 of the chute 12 of the linear feeder 11. Since the parts aligned in the R groove 14 can be sent to the alignment conveyance unit 15 in a good posture via the shape transition unit 16, the outlet of the R groove is directly connected to the inlet of the alignment conveyance unit. Compared to the case, the number of parts P excluded by the aligning and conveying unit 15 is small, and the parts supply capability can be improved.
 また、シュート12の搬送路13のR溝14と形状移行部16とのつなぎ目に面取り加工を施すとともに、形状移行部16を下流側に向かって2~5°の傾斜角度で下向きに傾斜させ、その長さを部品Pの長手方向寸法の5倍以上としたので、搬送速度が速い場合でも、部品PがスムーズにR溝14から形状移行部16へ乗り移って形状移行部16を通過していくことができ、部品詰まり等のトラブルも生じにくくなっている。 Further, chamfering is performed at the joint between the R groove 14 of the conveyance path 13 of the chute 12 and the shape transition portion 16, and the shape transition portion 16 is inclined downward at an inclination angle of 2 to 5 ° toward the downstream side. Since the length is 5 times or more the longitudinal dimension of the component P, the component P smoothly transfers from the R groove 14 to the shape transition portion 16 and passes through the shape transition portion 16 even when the conveyance speed is high. And troubles such as clogging of parts are less likely to occur.
 なお、本発明は、実施形態のようにボウルフィーダの下流側に直進フィーダを接続したものに限らず、部品を直線状の搬送路に沿って搬送する部品搬送部材を備え、その搬送路の上流側にR溝を設け、下流側に整列搬送部を設けた振動式部品搬送装置に広く適用することができる。 The present invention is not limited to a linear feeder connected to the downstream side of the bowl feeder as in the embodiment, but includes a component conveying member that conveys a component along a linear conveyance path, and is upstream of the conveyance path. The present invention can be widely applied to a vibration type component conveying apparatus in which an R groove is provided on the side and an alignment conveying unit is provided on the downstream side.
