JP 2004-43162 A

上記のように部品に気体を吹き付けて部品を整列させる機構を有する振動式部品供給装置の一例を、図4乃至図6に示す。この部品供給装置は、図4および図5に示すように、整列供給用トラフ51と、リターン用トラフ52と、各トラフ51、52と連結される振動体53と、振動体53と床Fとの間に介装される防振ゴム54とにより主要部が構成されたリターン式フィーダで、一端部が小径のゴム製筒状部品P(図6参照)を、振動体53の振動によって搬送しながら、整列供給用トラフ51の搬送路55途中に設けた部品整列部56で所定の姿勢に揃えて次工程に供給するものである。   An example of a vibrating component supply apparatus having a mechanism for aligning components by blowing gas onto the components as described above is shown in FIGS. As shown in FIGS. 4 and 5, this component supply apparatus includes an alignment supply trough 51, a return trough 52, a vibrating body 53 connected to each trough 51, 52, a vibrating body 53 and a floor F. A rubber-type cylindrical part P (see FIG. 6) having a small diameter at one end is conveyed by the vibration of the vibrating body 53. However, the parts are arranged in a predetermined posture and supplied to the next process by the parts alignment unit 56 provided in the middle of the conveying path 55 of the alignment supply trough 51.

ここで、図6に基づいて前記部品整列部56における部品Pの流れを詳述すると、整列供給用トラフ51の上流側から搬送されてきた部品Pは、まず、搬送路55の床に設けられた開口57から一端部を下向きにした姿勢で落下し、そのうちの多くが、搬送路55の下流側を構成するシュート58の搬送溝58aに嵌まり込んでシュート58排出端へ搬送されていく。そして、搬送溝58aに嵌まり込まなかった一部の部品Pは、シュート58上面に乗った状態で搬送される途中で、シュート58側方のノズル59から吹き付けられるエアによりシュート58から排除される。これにより、一端部が下向きの姿勢に整列された部品Pのみが次工程に供給される。また、シュート58から排除された部品Pは、整列供給用トラフ51の受板60またはリターン用トラフ52の戻し搬送路61に落下し、再び整列供給用トラフ51に供給される(図5参照)。   Here, the flow of the component P in the component alignment unit 56 will be described in detail with reference to FIG. 6. The component P conveyed from the upstream side of the alignment supply trough 51 is first provided on the floor of the conveyance path 55. From the opening 57, it falls in a posture in which one end portion is directed downward, most of which is fitted into the conveyance groove 58 a of the chute 58 that constitutes the downstream side of the conveyance path 55 and is conveyed to the discharge end of the chute 58. Then, some of the parts P that have not been fitted into the conveying groove 58a are removed from the chute 58 by the air blown from the nozzle 59 on the side of the chute 58 while being conveyed on the upper surface of the chute 58. . As a result, only the part P with one end aligned in a downward posture is supplied to the next process. Further, the part P removed from the chute 58 falls to the receiving plate 60 of the alignment supply trough 51 or the return conveyance path 61 of the return trough 52 and is supplied again to the alignment supply trough 51 (see FIG. 5). .

ところで、部品Pの材質が反発力の強いものである場合には、前記部品整列部56でエアによって吹き飛ばされた部品Pが、受板60または戻し搬送路61の床面に落下したときに大きく跳ね返る。そこで、受板60や戻し搬送路61の床面から跳ね返った部品Pがリターン用トラフ52の側壁を超えて装置外へ飛び出さないように、側壁を超えようとする部品Pを跳ね返すカバー62をリターン用トラフ52に取り付けている。   By the way, when the material of the component P has a strong repulsive force, the component P blown off by the air in the component aligning portion 56 is large when it falls on the floor surface of the receiving plate 60 or the return conveyance path 61. rebound. Therefore, a cover 62 that rebounds the part P that attempts to exceed the side wall is prevented so that the part P that rebounds from the floor surface of the receiving plate 60 and the return conveyance path 61 does not jump out of the apparatus beyond the side wall of the return trough 52. It is attached to the return trough 52.

しかしながら、前記カバー62は通常鉄や硬質の合成樹脂で形成されているので、カバー62に衝突した部品Pが再び大きく跳ね返り、シュート58を超えて装置外へ飛び出してしまうことがある。また、このカバー62は、受板60や戻し搬送路61の床面から不規則な方向に跳ね返ってくる部品Pの装置外への飛び出しを確実に阻止する必要があるので、サイズの大きいものになってしまうという難点があり、この例では、リターン用トラフ52のほぼ全長にわたって部品整列部56の上端位置よりもかなり高い位置まで設けられている(図4、図5参照)。なお、カバー62の設置位置をノズル59に近づけ、エアによって吹き飛ばされた部品Pが直接カバー62に衝突するようにすれば、カバー62の部品Pとの衝突領域が狭くなるので、カバー62を小型化することはできる。しかし、その場合には、部品Pがカバー62と衝突したときの衝撃が大きくなるため、部品Pのカバー62からの跳ね返りが大きくなり、多くの部品Pがシュート58を超えて装置外へ飛び出してしまうおそれがある。   However, since the cover 62 is usually formed of iron or hard synthetic resin, the part P that has collided with the cover 62 may bounce back again and jump out of the apparatus beyond the chute 58. Further, the cover 62 needs to surely prevent the part P that bounces off the floor surface of the receiving plate 60 and the return conveyance path 61 in an irregular direction from protruding out of the apparatus. In this example, the return trough 52 is provided over a substantially entire length up to a position considerably higher than the upper end position of the component alignment portion 56 (see FIGS. 4 and 5). If the installation position of the cover 62 is brought close to the nozzle 59 so that the component P blown off by the air directly collides with the cover 62, the collision area of the cover 62 with the component P becomes narrow. Can be However, in that case, since the impact when the component P collides with the cover 62 increases, the rebound of the component P from the cover 62 increases, and many components P jump out of the apparatus beyond the chute 58. There is a risk that.

本発明の課題は、部品に気体を吹き付けて部品を整列させる機構を備えた振動式部品供給装置において、気体を吹き付けられた部品の装置外への飛び出しを確実に防止できるようにすることである。   SUMMARY OF THE INVENTION An object of the present invention is to make it possible to reliably prevent a component sprayed with gas from jumping out of the device in a vibration-type component supply device having a mechanism for spraying gas onto components and aligning the components. .

上記の課題を解決するため、本発明は、部品搬送路の途中に、部品に気体を吹き付けて部品を整列させる機構を備えた部品整列部を設け、この部品整列部で姿勢を揃えた部品を次工程に供給する振動式部品供給装置において、前記搬送路を挟んで前記気体を吹き出すノズルの吹出口と対向する位置に、衝撃吸収性を有する材料で形成されたカバーを設けて、前記気体により搬送路から吹き飛ばされてカバーに衝突した部品の跳ね返りを抑えるようにした構成を採用した。   In order to solve the above-described problems, the present invention provides a component alignment unit having a mechanism for aligning components by blowing gas on the components in the middle of the component conveyance path. In the vibration type component supply apparatus to be supplied to the next process, a cover formed of a material having shock absorption is provided at a position facing a nozzle outlet that blows out the gas across the conveyance path. A configuration was adopted in which rebound of parts blown off from the conveyance path and colliding with the cover was suppressed.

すなわち、部品に吹き付けられる気体の吹出口と対向する位置に、衝撃吸収性を有する材料で形成されたカバーを設けることにより、気体によって吹き飛ばされた部品がカバーに衝突したときの衝撃がカバーで吸収されるようにして、部品のカバーからの跳ね返りを抑え、カバーから跳ね返った部品が装置外へ飛び出さないようにしたのである。   In other words, by providing a cover made of a material that absorbs shock at a position opposite to the gas outlet that is blown onto the component, the cover absorbs the shock when the component blown off by the gas collides with the cover. Thus, the bounce of the parts from the cover is suppressed, and the parts bounced off the cover are prevented from jumping out of the apparatus.

前記カバーを形成する材料としては、軟質のポリ塩化ビニルを採用することができる。   As a material for forming the cover, soft polyvinyl chloride can be used.

また、前記カバーに、部品が通過できない幅のスリットを複数設けることにより、カバーがさらに衝撃を吸収しやすくなり、部品の装置外への飛び出しをより確実に防止することができる。   Further, by providing a plurality of slits with a width through which parts cannot pass through the cover, the cover can more easily absorb the impact, and the parts can be more reliably prevented from jumping out of the apparatus.

本発明の振動式部品供給装置は、上述したように、部品に吹き付けられる気体の吹出口と対向する位置に、衝撃吸収性を有する材料で形成されたカバーを設けて、気体により搬送路から吹き飛ばされてカバーに衝突した部品の跳ね返りを抑えるようにしたものであるから、部品の装置外への飛び出しを確実に防止できるし、カバーを従来よりも気体の吹出口に近い位置に設置してカバーのコンパクト化を図ることができる。   As described above, the vibration type component supply device of the present invention is provided with a cover formed of a material having shock absorption at a position facing a gas outlet that is blown onto the component, and blows off the conveyance path with gas. This prevents the parts that have collided with the cover from bouncing off, so that the parts can be reliably prevented from jumping out of the device, and the cover can be installed closer to the gas outlet than before. Can be made compact.

以下、図1乃至図3に基づき、本発明の実施形態を説明する。この振動式部品供給装置の基本的な構成は、前述した従来の装置と同じである。すなわち、この部品供給装置は、図1および図2に示すように、整列供給用トラフ1と、リターン用トラフ2と、各トラフ1、2と連結される振動体3と、振動体3と床Fとの間に介装される防振ゴム4とにより主要部が構成されたリターン式フィーダで、一端部が小径のゴム製筒状部品P(図3参照)を、振動体3の振動によって搬送しながら、整列供給用トラフ1の搬送路5途中に設けた部品整列部6で所定の姿勢に揃えて次工程に供給するものである。また、装置内側で部品整列部6と対向する位置に、部品整列部6で搬送路5から排除された部品Pの装置外への飛び出しを防止するためのカバー7が設けられている。   Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3. The basic configuration of the vibratory component supply device is the same as the conventional device described above. That is, as shown in FIGS. 1 and 2, the component supply apparatus includes an alignment supply trough 1, a return trough 2, a vibrating body 3 connected to the troughs 1 and 2, a vibrating body 3 and a floor. A rubber-type cylindrical part P (see FIG. 3) whose one end is a small diameter is returned by vibration of the vibrating body 3. While transporting, the parts aligning section 6 provided in the middle of the transport path 5 of the alignment supply trough 1 is supplied to the next process in a predetermined posture. In addition, a cover 7 is provided at a position facing the component alignment unit 6 inside the device to prevent the component P removed from the conveyance path 5 by the component alignment unit 6 from jumping out of the device.

前記整列供給用トラフ1は、部品Pを搬送路5に沿って図面左方向へ搬送し、その排出端から次工程に供給するもので、上流部分が緩やかな上り勾配の傾斜部8となっており、その下流側に部品整列部6が設けられている。その搬送路5の一側には、搬送路5から排除された部品Pを受けてリターン用トラフ2に送る受板9が取り付けられている。   The alignment supply trough 1 conveys the component P in the left direction of the drawing along the conveyance path 5 and supplies it to the next process from its discharge end. The component alignment portion 6 is provided on the downstream side. A receiving plate 9 is attached to one side of the conveyance path 5 to receive the component P removed from the conveyance path 5 and send it to the return trough 2.

また、前記リターン用トラフ2は、受板9排出端の側方から搬送路5供給端の側方まで延びる上り勾配の戻し搬送路10を有しており、この戻し搬送路10で整列供給用トラフ1の受板9から受け取った部品Pを図面右方向へ搬送し、再び整列供給用トラフ1に供給するものである。   The return trough 2 has an upwardly inclined return conveyance path 10 extending from the side of the discharge end of the receiving plate 9 to the side of the conveyance path 5 supply end. The component P received from the receiving plate 9 of the trough 1 is conveyed rightward in the drawing and is supplied again to the alignment supply trough 1.

前記整列供給用トラフ1の部品整列部6は、図3に示すように、その上流側の傾斜部8から搬送されてきた部品Pを、搬送路5の床に設けた開口11から一端部が下向きの姿勢で落下させて、搬送路5の下流側を構成するシュート12の搬送溝12aに嵌め込んだ状態でシュート12排出端へ搬送していくものである。そして、搬送溝12aに嵌まり込まなかった一部の部品Pは、シュート12上面に乗った状態で搬送される途中で、シュート12側方のノズル13から吹き付けられるエアによりシュート12から排除され、一端部が下向きの姿勢に整列された部品Pのみが次工程に供給される。   As shown in FIG. 3, the component aligning section 6 of the alignment supply trough 1 is configured such that one end portion of the component P conveyed from the upstream inclined portion 8 is opened from the opening 11 provided on the floor of the conveying path 5. It is dropped in a downward posture and conveyed to the discharge end of the chute 12 in a state where it is fitted in the conveyance groove 12a of the chute 12 constituting the downstream side of the conveyance path 5. And some parts P which did not fit in the conveyance groove 12a are excluded from the chute 12 by the air blown from the nozzle 13 on the side of the chute 12 while being conveyed while being on the upper surface of the chute 12. Only the component P having one end aligned in a downward posture is supplied to the next process.

前記カバー7は、床Fから立ち上がる支柱14の上端部に固定された天板15から、受板9の内側端部の床面近傍まで垂下するように配設されており、シュート12を挟んでノズル13の吹出口と対向して、エアによりシュート12から吹き飛ばされた部品Pを跳ね返すようになっている。このカバー7は、衝撃吸収性に優れた軟質のポリ塩化ビニルで形成されているうえ、さらに衝撃を吸収しやすくなるように、その下端から上方に切れ込むスリット7aが部品Pを通過させない幅で複数設けられている(図1参照)。   The cover 7 is disposed so as to hang down from the top plate 15 fixed to the upper end of the column 14 rising from the floor F to the vicinity of the floor surface of the inner end of the receiving plate 9. The part P blown off from the chute 12 by air is rebounded so as to face the air outlet of the nozzle 13. The cover 7 is made of soft polyvinyl chloride excellent in shock absorption, and a plurality of slits 7a cut upward from the lower end of the cover 7 so as not to allow the component P to pass therethrough so that the shock can be easily absorbed. Provided (see FIG. 1).

なお、カバー7の材質はポリ塩化ビニルに限らず、例えばゴム、シリコーン等、衝撃吸収性を有するものであればよい。また、カバー7の色は透明でも有色でもよいが、この例では、部品整列部6での部品Pの搬送状態が目視確認しやすいように透明としている。また、カバー7の厚さは、整列供給の対象となる部品Pの大きさや材質等に基づいて適切に設計すればよい。   The material of the cover 7 is not limited to polyvinyl chloride, and may be any material having shock absorption, such as rubber or silicone. The color of the cover 7 may be transparent or colored, but in this example, the cover 7 is transparent so that the conveying state of the component P in the component aligning unit 6 can be easily visually confirmed. Further, the thickness of the cover 7 may be appropriately designed based on the size, material, etc. of the parts P to be aligned and supplied.

この部品供給装置は、上記の構成であり、図3に示したように、部品整列部6ではエアで吹き飛ばされた部品Pが直接カバー7に衝突するが、その衝撃がカバー7で吸収されるため、カバー7に衝突した部品Pは大きく跳ね返ることなくカバー7のほぼ直下の受板9床面に落下し、装置外へ飛び出すおそれがない。しかも、カバー7をノズル13に近い位置、すなわちエアで吹き飛ばされた部品Pが直接衝突する位置に設置できるので、カバー7全体を非常にコンパクトなものとすることができる。   This component supply apparatus has the above-described configuration. As shown in FIG. 3, the component P blown by air directly collides with the cover 7 in the component aligning unit 6, but the impact is absorbed by the cover 7. Therefore, the part P that has collided with the cover 7 does not largely bounce off and falls to the floor surface of the receiving plate 9 almost directly below the cover 7, so that there is no possibility of jumping out of the apparatus. Moreover, since the cover 7 can be installed at a position close to the nozzle 13, that is, a position where the component P blown off with air directly collides, the entire cover 7 can be made very compact.

なお、上述した実施形態では、部品整列部の1箇所で部品に気体を吹き付ける場合について説明したが、複数個所で部品に気体を吹き付ける場合は、各箇所の気体吹出口と対向するカバーを別々に設けてもよいし、一体に設けるようにしてもよい。   In the above-described embodiment, the case where the gas is blown onto the component at one location of the component aligning portion has been described. However, when the gas is blown onto the component at a plurality of locations, the cover facing the gas outlet at each location is separately provided. It may be provided or may be provided integrally.

また、本発明は、実施形態のように所定の姿勢でない部品を気体で搬送路から排除する機構を備えた装置に限らず、部品に気体を吹き付けて部品を整列させる装置に広く適用することができる。例えば、互いに張り付いた部品に搬送路床面に設けたノズルから気体を吹き上げ、部品を天板に衝突させて部品の貼り付きを解除する機構を備えた装置では、解除機構側面部を実施形態のカバーと同様に衝撃吸収性を有する材料で形成することにより、天板に衝突した部品が搬送路と天板との間の隙間から装置外へ飛び出さないようにすることができる。   In addition, the present invention is not limited to an apparatus having a mechanism for excluding a part that is not in a predetermined posture from the conveyance path with gas as in the embodiment, and can be widely applied to an apparatus that aligns parts by blowing gas onto the parts. it can. For example, in an apparatus equipped with a mechanism that releases gas from nozzles provided on the conveyance path floor surface to parts stuck to each other and causes the parts to collide with the top plate to release the sticking of the parts, the release mechanism side part is an embodiment. By forming the shock absorbing material in the same manner as the cover, it is possible to prevent components that collide with the top plate from jumping out of the apparatus through the gap between the transport path and the top plate.
