Description

振動式部品搬送装置Vibrating parts conveyor

　本発明は、加振機構が発生させる加振力により、トラフ等の部品搬送部材を振動させて部品を直線的に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 conveys a component linearly by vibrating a component conveying member such as a trough by an excitation force generated by an excitation mechanism.

　振動式部品搬送装置は、各種の機器の製造工程等において部品を整列搬送して後工程へ供給する手段としてよく用いられる。その一般的な構造は、基台とその上方に配置される上部振動体とを傾斜した姿勢の板ばねで連結し、直線状の部品搬送路を有する整列供給用トラフ（部品搬送部材）を上部振動体に取り付け、加振機構が発生させる加振力により、上部振動体および整列供給用トラフを部品搬送方向および鉛直方向に振動させて、部品を直線的にほぼ水平に搬送しながら整列させるものが多い。 The vibration-type component conveying device is often used as a means for aligning and conveying components and supplying them to subsequent processes in the manufacturing process of various devices. The general structure is that the base and the upper vibrator arranged above it are connected by an inclined leaf spring, and an alignment supply trough (part transport member) having a straight part transport path is placed on the top. Attached to the vibrating body, the upper vibrating body and the alignment trough are vibrated in the parts transport direction and the vertical direction by the vibration force generated by the vibration mechanism, and the parts are aligned while being linearly transported almost horizontally. There are many.

　ところが、このような振動式部品搬送装置では、上部振動体の振動の反力によって基台にも振動が発生し、その振動が床面（床の基台設置面）へ伝搬して、同じ床面上に設置されている他の機器の動作に影響を及ぼす場合がある。 However, in such a vibration type component conveying device, vibration is also generated in the base due to the reaction force of the vibration of the upper vibration body, and the vibration propagates to the floor (floor base installation surface), and the same floor May affect the operation of other equipment installed on the surface.

　これに対し、前述の一般的な構造に加えて、上部振動体と並列に配置したカウンタ振動体にリターン用トラフ（部品返送部材）を取り付けた振動式部品搬送装置では、通常、そのカウンタ振動体を上部振動体用の板ばねと逆向きに傾斜する板ばねで基台に連結して、加振機構で上部振動体と逆位相で振動させることにより、リターン用トラフで部品を整列供給用トラフと逆方向に搬送するとともに、上部振動体の振動によって基台が受ける水平方向の反力とカウンタ振動体の振動によって基台が受ける水平方向の反力とを相殺して（打ち消し合わせて）、床面への振動の伝搬を抑えるようにしている（例えば、下記特許文献１参照。）。しかし、このようにした場合、各振動体の振動によって基台が受ける鉛直方向の反力は加算されるので、基台から床面への鉛直方向振動の伝搬は増大することになる。 On the other hand, in addition to the general structure described above, in a vibration type component transport apparatus in which a return trough (component return member) is attached to a counter vibration body arranged in parallel with the upper vibration body, the counter vibration body is usually used. Are connected to the base with a leaf spring inclined in the opposite direction to the leaf spring for the upper vibration body, and the vibration is caused to vibrate in the opposite phase to the upper vibration body by the vibration mechanism, so that the parts can be arranged with the return trough. And counteract the horizontal reaction force received by the base due to the vibration of the upper vibrating body and the horizontal reaction force received by the base due to the vibration of the counter vibration body (cancelled) The propagation of vibration to the floor surface is suppressed (see, for example, Patent Document 1 below). However, in this case, since the vertical reaction force received by the base due to the vibration of each vibrating body is added, the propagation of the vertical vibration from the base to the floor surface increases.

　一方、上記と同じようにリターン用トラフで部品を整列供給用トラフと逆方向に搬送するようにした振動式部品搬送装置のうちでも、上部振動体と基台を連結する板ばねと同じ向きに傾斜させた板ばねで、リターン用トラフを上部振動体に連結したもの（下記特許文献２参照。）では、水平方向にも鉛直方向にも基台が受ける反力を相殺する構造とはなっていないため、その両方向の振動が基台から床面へ伝搬することになる。 On the other hand, in the same manner as described above, even in the vibration type component conveying device in which the component is conveyed in the reverse direction by the return trough by the return trough, it is in the same direction as the leaf spring connecting the upper vibrating body and the base. An inclined leaf spring in which the return trough is connected to the upper vibrating body (see Patent Document 2 below) has a structure that cancels the reaction force received by the base both in the horizontal direction and in the vertical direction. Therefore, the vibrations in both directions propagate from the base to the floor surface.

　このため、通常は、どのようなタイプの振動式部品搬送装置でも、基台の質量を大きくしたり、基台と床面との間に防振ばねを設けたりしているが、基台の振動を十分に小さくしたり吸収したりすることができず、基台の振動が床面へ少なからず伝搬してしまうおそれがある。 For this reason, in general, any type of vibratory component conveying device has a large base mass or a vibration-proof spring provided between the base and the floor surface. The vibration cannot be sufficiently reduced or absorbed, and the vibration of the base may propagate to the floor surface.

　そこで、本発明は、部品を直線的に搬送する振動式部品搬送装置において、基台が設置される床面への水平方向振動および鉛直方向振動の伝搬を効果的に抑制することを課題とする。 Therefore, an object of the present invention is to effectively suppress the propagation of horizontal vibration and vertical vibration to a floor surface on which a base is installed in a vibration type component conveying apparatus that conveys components linearly. .

　上記の課題を解決するため、本発明は、直線状の部品搬送路を有する部品搬送部材と、前記部品搬送部材が取り付けられる上部振動体と、前記上部振動体に並設されるカウンタ振動体と、床上に設置される基台と、前記上部振動体と基台とを連結する第１の弾性部材と、前記カウンタ振動体と基台とを連結する第２の弾性部材と、前記上部振動体とカウンタ振動体に互いに逆位相の振動を付与する加振機構とを備えた振動式部品搬送装置において、前記第１の弾性部材と第２の弾性部材を同じ向きに傾斜した状態で配置した構成を採用した。 In order to solve the above-described problems, the present invention provides a component conveying member having a linear component conveying path, an upper vibrating body to which the component conveying member is attached, and a counter vibrating body provided in parallel with the upper vibrating body. A base installed on the floor, a first elastic member that connects the upper vibrator and the base, a second elastic member that connects the counter vibrator and the base, and the upper vibrator And a vibration-type component conveying device provided with vibration mechanisms for applying counter-phase vibrations to the counter vibrating body, wherein the first elastic member and the second elastic member are arranged in a state of being inclined in the same direction. It was adopted.

　すなわち、部品搬送部材が取り付けられる上部振動体と、上部振動体に並設されるカウンタ振動体を、同じ向きに傾斜した第１の弾性部材と第２の弾性部材によってそれぞれ基台に連結して互いに逆位相で振動させることにより、各振動体の振動によって基台が受ける水平方向の反力と鉛直方向の反力がいずれも相殺されて、基台の水平方向振動および鉛直方向振動が小さくなり、基台から床面への水平方向振動および鉛直方向振動の伝搬を効果的に抑えられるようにしたのである。 That is, the upper vibrating body to which the component conveying member is attached and the counter vibrating body arranged in parallel with the upper vibrating body are connected to the base by the first elastic member and the second elastic member inclined in the same direction, respectively. By oscillating in opposite phases, the horizontal reaction force and vertical reaction force received by the base due to the vibration of each vibrating body are canceled out, and the horizontal vibration and vertical vibration of the base are reduced. The propagation of horizontal vibration and vertical vibration from the base to the floor surface can be effectively suppressed.

　上記の構成においては、前記カウンタ振動体と直線状の部品返送路を有する部品返送部材とを、前記第１の弾性部材および第２の弾性部材と同じ向きに傾斜させた第３の弾性部材で連結することにより、部品返送部材に鉛直方向の振動の向きがカウンタ振動体と逆向きの振動を発生させて、その部品返送路上の部品を部品搬送部材と逆方向に搬送させることができる。 In the above configuration, the counter vibrating body and the component return member having a linear component return path are made of a third elastic member that is inclined in the same direction as the first elastic member and the second elastic member. By connecting, it is possible to cause the component return member to vibrate in the direction opposite to the counter vibrating body in the vertical direction, and to convey the component on the component return path in the direction opposite to the component conveying member.

　また、前記加振機構を、前記上部振動体とカウンタ振動体のうちの一方の振動体に取り付けられる電磁石と、他方の振動体に取り付けられる磁性体との間で加振力を発生させるものとすれば、各振動体に付与する加振力が同じ大きさになるので、より確実に基台が受ける反力を相殺でき、床面への振動の伝搬を一層効果的に抑制することができる。 And the vibration generating mechanism generates a vibration force between an electromagnet attached to one of the upper vibrator and the counter vibrator and a magnetic body attached to the other vibrator. As a result, the excitation force applied to each vibrating body has the same magnitude, so the reaction force received by the base can be more reliably offset, and the propagation of vibration to the floor surface can be more effectively suppressed. .

　本発明の振動式部品搬送装置は、上述したように、部品搬送部材が取り付けられる上部振動体と、上部振動体に並設されるカウンタ振動体を、同じ向きに傾斜した第１の弾性部材と第２の弾性部材によってそれぞれ基台に連結して互いに逆位相で振動させるようにしたものであるから、各振動体の振動によって基台が受ける水平方向の反力と鉛直方向の反力をいずれも相殺して、基台から床面への水平方向振動および鉛直方向振動の伝搬を効果的に抑えることができる。したがって、従来よりも周囲の機器への影響を抑えるための制約が少なく、部品搬送部材の振動の振幅を大きくしたり周波数を高くしたりして部品搬送の高速化を実現することができる。 As described above, the vibration type component conveying apparatus of the present invention includes the upper vibrating body to which the component conveying member is attached, and the first elastic member in which the counter vibrating body provided in parallel with the upper vibrating body is inclined in the same direction. Since each of the second elastic members is connected to the base and vibrates in the opposite phase, the horizontal reaction force and the vertical reaction force received by the base due to the vibration of each vibrating body are Can be canceled out, and propagation of horizontal vibration and vertical vibration from the base to the floor can be effectively suppressed. Therefore, there are fewer restrictions for suppressing the influence on surrounding devices than in the past, and it is possible to increase the speed of component conveyance by increasing the amplitude of the vibration of the component conveyance member or increasing the frequency.

　以下、図面に基づき、本発明の実施形態を説明する。図１および図２は第１の実施形態を示す。この振動式部品搬送装置は、直線状の部品搬送路１ａが形成された整列供給用トラフ（部品搬送部材）１と、整列供給用トラフ１が取り付けられる上部振動体２と、上部振動体２を囲む（接触はしない）ように配置される矩形枠状のカウンタ振動体３と、床上に設置される基台４と、上部振動体２と基台４とを連結する前後一対の第１の板ばね（第１の弾性部材）５と、第１の板ばね５を幅方向で挟む位置でカウンタ振動体３と基台４とを連結する前後二対の第２の板ばね（第２の弾性部材）６と、上部振動体２とカウンタ振動体３の間に設置される加振機構７とを備えている。なお、基台４は、直接床面（または床上の設置台）に固定してもよいし、防振ゴムや防振ばねのような防振部材を介して床面に固定してもよい。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 show a first embodiment. The vibration type component conveying apparatus includes an alignment supply trough (component conveyance member) 1 in which a linear component conveyance path 1a is formed, an upper vibration body 2 to which the alignment supply trough 1 is attached, and an upper vibration body 2. A rectangular frame-shaped counter vibrating body 3 arranged so as to surround (not contact), a base 4 installed on the floor, and a pair of front and rear first plates for connecting the upper vibrating body 2 and the base 4 Two pairs of front and rear second leaf springs (second elasticity) connecting the counter vibrating body 3 and the base 4 at a position sandwiching the spring (first elastic member) 5 and the first leaf spring 5 in the width direction. Member) 6 and a vibration mechanism 7 installed between the upper vibration body 2 and the counter vibration body 3. The base 4 may be directly fixed to the floor surface (or the installation base on the floor), or may be fixed to the floor surface via a vibration-proof member such as a vibration-proof rubber or a vibration-proof spring.

　前記第１の板ばね５は、部品搬送方向（Ｘ方向）の後方（図１、図２の左側）へ傾斜した状態で、上端部を上部振動体２に下端部を基台４にそれぞれ固定されている。そして、前記第２の板ばね６は、第１の板ばね５と同じ向きに傾斜した状態で、上端部をカウンタ振動体３に下端部を基台４にそれぞれ固定されている。 The first leaf spring 5 is fixed to the upper vibrator 2 and the lower end to the base 4 with the upper end inclined to the rear (left side in FIGS. 1 and 2) in the component conveying direction (X direction). Has been. The second leaf spring 6 is fixed to the counter vibrating body 3 at its upper end and to the base 4 at its lower end, while being inclined in the same direction as the first leaf spring 5.

　前記加振機構７は、上部振動体２の下面側に取り付けられる電磁石８と、カウンタ振動体３の下面側に取り付けられる磁性体としての可動鉄芯９とを、Ｘ方向で所定の間隔をおいて対向するように配置し、電磁石８に通電して吸引力を作用させることにより、電磁石８と可動鉄芯９との間で加振力を発生させるものである。なお、この実施形態と逆に、電磁石８をカウンタ振動体３に取り付け、可動鉄芯９を上部振動体２に取り付けるようにしてもよい。また、可動鉄芯９に代わる他の磁性体を用いることもできる。 The vibration mechanism 7 has an electromagnet 8 attached to the lower surface side of the upper vibrator 2 and a movable iron core 9 as a magnetic body attached to the lower surface side of the counter vibrator 3 with a predetermined interval in the X direction. Thus, an exciting force is generated between the electromagnet 8 and the movable iron core 9 by energizing the electromagnet 8 and applying an attractive force thereto. In contrast to this embodiment, the electromagnet 8 may be attached to the counter vibrator 3 and the movable iron core 9 may be attached to the upper vibrator 2. In addition, other magnetic bodies in place of the movable iron core 9 can be used.

　そして、この加振機構７の電磁石８に通電して加振力を発生させると、Ｘ方向および鉛直方向（Ｚ方向）の振動が上部振動体２とカウンタ振動体３に互いに逆位相で付与され、上部振動体２と一体に振動する整列供給用トラフ１の部品搬送路１ａ上の部品がＸ方向の前方に搬送される。 When the electromagnet 8 of the vibration mechanism 7 is energized to generate a vibration force, vibrations in the X direction and the vertical direction (Z direction) are applied to the upper vibration body 2 and the counter vibration body 3 in opposite phases. The parts on the part transport path 1a of the alignment supply trough 1 that vibrate integrally with the upper vibrator 2 are transported forward in the X direction.

　ここで、図示は省略するが、上部振動体２と一体に振動する上部振動系（整列供給用トラフ１と電磁石８を含む）の重心と、カウンタ振動体３と一体に振動するカウンタ振動系（可動鉄芯９を含む）の重心とは、Ｘ方向およびＺ方向と直交する方向をＹ方向とするとき、Ｙ方向とＺ方向で形成される１つのＹＺ平面Ｐに対して対称となるように配置されている。そして、各部材の素材を適切に選定して上部振動系とカウンタ振動系の質量をほぼ同一に調整するとともに、両振動系の固有振動数を一致させて周波数特性を同じにすることにより、両振動系のＸ方向およびＺ方向の振動波形を逆位相で振動の大きさがほぼ同じになるようにしている。これにより、上部振動体２とカウンタ振動体３の振動によって基台４が受ける水平方向の反力と鉛直方向の反力はいずれも確実に相殺されることになる。 Here, although not shown, the center of gravity of the upper vibration system (including the alignment supply trough 1 and the electromagnet 8) that vibrates integrally with the upper vibration body 2 and the counter vibration system (vibrating integrally with the counter vibration body 3). The center of gravity (including the movable iron core 9) is symmetric with respect to one YZ plane P formed in the Y direction and the Z direction when the direction perpendicular to the X direction and the Z direction is the Y direction. Has been placed. By appropriately selecting the material of each member and adjusting the masses of the upper vibration system and the counter vibration system to be approximately the same, the frequency characteristics are made the same by matching the natural frequencies of both vibration systems. The vibration waveforms in the X direction and the Z direction of the vibration system are made in opposite phases and the magnitude of vibration is made substantially the same. Thereby, both the horizontal reaction force and the vertical reaction force received by the base 4 due to the vibrations of the upper vibration body 2 and the counter vibration body 3 are surely offset.

　この振動式部品搬送装置は、上述したように、上部振動体２とカウンタ振動体３を、同じ向きに傾斜した第１の板ばね５と第２の板ばね６によってそれぞれ基台４に連結して、互いに逆位相でかつ同じ大きさの振幅で振動させることにより、基台４が受ける水平方向の反力と鉛直方向の反力がいずれも相殺されるようにしたので、基台４には水平方向の振動も鉛直方向の振動も生じにくく、基台４から床面へはほとんど振動が伝搬しない。したがって、周囲の機器への影響をほとんど考慮することなく、整列供給用トラフ１の振動の振幅を大きくしたり周波数を高くしたりして、高速で部品搬送を行うことができる。 As described above, the vibration type component conveying apparatus connects the upper vibrating body 2 and the counter vibrating body 3 to the base 4 by the first leaf spring 5 and the second leaf spring 6 that are inclined in the same direction. Thus, the horizontal and vertical reaction forces received by the base 4 are canceled out by oscillating with the same magnitude and amplitude opposite to each other. Both horizontal and vertical vibrations are unlikely to occur, and vibration hardly propagates from the base 4 to the floor surface. Therefore, it is possible to carry parts at a high speed by increasing the amplitude of the vibration of the alignment supply trough 1 or increasing the frequency without considering the influence on the surrounding equipment.

　しかも、上部振動系の重心とカウンタ振動系の重心を１つのＹＺ平面Ｐに対して対称に配置して、基台４が受ける反力が同一のＸＺ平面上で打ち消し合うようにしたので、基台４の重心を通る鉛直軸（Ｚ軸）の回りのモーメントが発生せず、ヨーイング運動を起こすことなく安定した部品搬送を行うことができる。なお、この実施形態では、上部振動系の重心とカウンタ振動系の重心を異なる位置としたが、同一の位置にあればもちろんこれと同様の効果が得られる。 In addition, since the center of gravity of the upper vibration system and the center of gravity of the counter vibration system are arranged symmetrically with respect to one YZ plane P, the reaction forces received by the base 4 cancel each other on the same XZ plane. A moment around a vertical axis (Z axis) passing through the center of gravity of the table 4 is not generated, and stable component conveyance can be performed without causing a yawing motion. In this embodiment, the center of gravity of the upper vibration system and the center of gravity of the counter vibration system are set at different positions. However, the same effect can be obtained as long as they are at the same position.

　また、加振機構は、一般に実施されているように、基台に電磁石を設置し、上部振動体とカウンタ振動体のそれぞれに磁性体を取り付ける（加振機構を２つにする）ことも考えられるが、実施形態のように加振機構を１つにした方が、確実に基台が受ける反力を相殺できるので好ましい。 In addition, as is generally practiced, the vibration mechanism may have an electromagnet installed on the base, and a magnetic body is attached to each of the upper vibration body and the counter vibration body (two vibration mechanisms are used). However, it is preferable to use one vibration mechanism as in the embodiment because the reaction force received by the base can be surely offset.

　次に、上述した第１実施形態をベースとして、整列供給用トラフ１で姿勢不良となった部品を整列供給用トラフ１と逆方向に搬送できるようにした例（第２、第３の実施形態）について説明する。なお、第１実施形態と同じ機能を有する部材については、同じ符号を付けて説明を省略する。 Next, on the basis of the first embodiment described above, an example in which a component whose posture is poor in the alignment supply trough 1 can be conveyed in the direction opposite to that of the alignment supply trough 1 (second and third embodiments). ). In addition, about the member which has the same function as 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

　図３および図４は第２の実施形態を示す。この実施形態では、カウンタ振動体３に取り付けた連結部材１０と、直線状の部品返送路１１ａを有するリターン用トラフ（部品返送部材）１１とを、第１の板ばね５および第２の板ばね６と同じ向きに傾斜させた前後一対の第３の板ばね１２で連結して、部品返送路１１ａ上の部品を整列供給用トラフ１と逆方向に搬送できるようにしている。そして、整列供給用トラフ１に、姿勢不良の部品を部品搬送路１ａから排除する選別部１３と、選別部１３で排除された部品をリターン用トラフ１１の部品返送路１１ａへ向けて排出する排出部１４を設けている。これにより、整列供給用トラフ１の部品搬送路１ａから排除された部品が、リターン用トラフ１１へ送られて整列供給用トラフ１と逆方向に搬送され、整列供給用トラフ１の上流側に接続されているボウルフィーダ等（図示省略）に戻されるようになっている。 3 and 4 show a second embodiment. In this embodiment, the connecting member 10 attached to the counter vibrating body 3 and the return trough (part return member) 11 having the linear part return path 11a are connected to the first leaf spring 5 and the second leaf spring. 6 are connected by a pair of front and rear third leaf springs 12 inclined in the same direction as 6, so that the components on the component return path 11 a can be conveyed in the opposite direction to the alignment supply trough 1. Then, a sorting unit 13 that removes components with poor posture from the component transport path 1 a and a discharge that ejects the components removed by the sorting unit 13 toward the component return path 11 a of the return trough 11. A portion 14 is provided. As a result, the parts removed from the parts conveying path 1 a of the alignment supply trough 1 are sent to the return trough 11 and conveyed in the opposite direction to the alignment supply trough 1, and connected to the upstream side of the alignment supply trough 1. It is returned to a bowl feeder or the like (not shown).

　図５および図６に示す第３の実施形態は、第２実施形態のリターン用トラフ１１に、その部品返送路１１ａの下流端から整列供給用トラフ１の部品搬送路１ａの上流端に部品を送る送出部１５を設けて、リターン用トラフ１１で整列供給用トラフ１と逆方向に搬送された部品を、前記ボウルフィーダ等を介さずに直接整列供給用トラフ１に戻して再び整列搬送するようにしたものである。 In the third embodiment shown in FIG. 5 and FIG. 6, the return trough 11 of the second embodiment is arranged with components from the downstream end of the component return path 11a to the upstream end of the component transport path 1a of the alignment supply trough 1. A sending-out section 15 is provided, and the parts conveyed in the direction opposite to the alignment supply trough 1 by the return trough 11 are directly returned to the alignment supply trough 1 without passing through the bowl feeder or the like, and are again aligned and conveyed. It is a thing.

　そして、図７および図８は、第３実施形態のカウンタ振動体３のリターン用トラフ１１が設けられていない方の長辺部に、カウンタ振動系の重心のＹ方向位置を調整するための錘１６を設けた変形例である。この変形例では、図３および図４に示した第２実施形態や図５および図６に示した例に比べて、容易にカウンタ振動系の重心をＹＺ平面Ｐに対して上部振動系の重心と対称となるように配置することができ、ヨーイング運動を効果的に防止できる。 7 and 8 show weights for adjusting the Y-direction position of the center of gravity of the counter vibration system on the long side portion of the counter vibration body 3 of the third embodiment where the return trough 11 is not provided. 16 is a modified example. In this modification, the center of gravity of the counter vibration system can be easily set to the center of gravity of the upper vibration system with respect to the YZ plane P as compared to the second embodiment shown in FIGS. 3 and 4 and the examples shown in FIGS. It can arrange | position so that it may become symmetrical, and a yawing motion can be prevented effectively.

　上述した各実施形態では、上部振動体を囲むように矩形枠状のカウンタ振動体を配置した例を示したが、本発明は、種々の形態で上部振動体とカウンタ振動体を並設した振動式部品搬送装置に広く適用することができる。 In each of the embodiments described above, an example in which a rectangular frame-shaped counter vibrating body is disposed so as to surround the upper vibrating body has been described. However, the present invention is a vibration in which the upper vibrating body and the counter vibrating body are arranged in parallel in various forms. The present invention can be widely applied to a type parts conveying apparatus.
