Description
本発明はU字状に形成され、一方の舌片にネジ嵌通孔を備えたスピードナットを供給するスピードナットの供給組付装置に関するものである。 The present invention relates to a speed nut supply and assembly device that supplies speed nuts that are U-shaped and have a screw-insertion hole on one of the tongues.
従来この種の装置は、特許文献１に記載されているように、ワークに挿着するスピードナットを握持するスピードナット握持手段と、その開放により前記スピードナットの取込みを自在とし、前記ワークを挟持自在なワーク挟持手段と、前記ワーク挟持手段が前記ワークを挟持した状態で、前記ワークと前記スピードナット握持手段で握持した前記スピードナットとの相対移動を行い、前記ワークに対して前記スピードナットの押し込みを行う移動手段を具備し、前記スピードナット握持手段は前記移動手段に軸支されており、軸支しているレバーの一端にスピードナット握持手段を前記レバーの他端に相対移動用のレバーを有するようになっていた。 As described in Patent Document 1, this type of device conventionally includes a speed nut gripping means for gripping a speed nut to be inserted into a workpiece, a workpiece clamping means for freely gripping the workpiece by opening the gripping means to allow the speed nut to be freely taken in, and a moving means for moving the workpiece and the speed nut gripped by the speed nut gripping means relative to each other while the workpiece clamping means is clamping the workpiece, and for pushing the speed nut into the workpiece. The speed nut gripping means is journaled on the moving means, and the journaled lever has the speed nut gripping means at one end and a lever for relative movement at the other end of the lever.
特許文献１記載のスピードナット自動供給組付装置は、ワークに挿着するスピードナットを握持するスピードナット握持手段と、その開放により前記スピードナットの取込みを自在とし、前記ワークを挟持自在なワーク挟持手段と、前記ワーク挟持手段が前記ワークを挟持した状態で、前記ワークと前記スピードナット握持手段で握持した前記スピードナットとの相対移動を行い、前記ワークに対して前記スピードナットの押し込みを行う移動手段を具備し、前記スピードナット握持手段は前記移動手段に軸支されており、軸支しているレバーの一端にスピードナット握持手段を前記レバーの他端に相対移動用のレバーを有するようになっていたので、スピードナット握持手段で握持したスピードナットをワーク側に移動させようとしたとき、レバーの中央付近が軸支されているために、握持したスピードナットの移動できる範囲が著しく狭い範囲に限られ、スピードナットはワークに対して極浅くしか挿着できないという課題があった。 The speed nut automatic supply and assembly device described in Patent Document 1 is equipped with a speed nut gripping means for gripping a speed nut to be inserted into a workpiece, a workpiece clamping means for freely gripping the workpiece by opening the gripping means to freely take in the speed nut, and a moving means for relatively moving the workpiece and the speed nut gripped by the speed nut gripping means while the workpiece clamping means is clamping the workpiece, and for pushing the speed nut into the workpiece. The speed nut gripping means is pivotally supported by the moving means, and one end of the pivotally supported lever has the speed nut gripping means, and the other end of the lever has a lever for relative movement. Therefore, when an attempt is made to move the speed nut gripped by the speed nut gripping means toward the workpiece, the lever is pivotally supported near the center, so that the range over which the gripped speed nut can move is extremely narrow, and the speed nut can only be inserted very shallowly into the workpiece.

図１～図６を用いて本発明を適用した第一実施形態のスピードナット自動供給組付装置について説明する。図１は本発明第一実施例のスピードナット自動供給組付装置のピッキング部とピッキング駆動部の動作状態を示す側面図、図２は本発明第一実施例のスピードナット自動供給組付装置およびワーク供給部の側面図、図３（Ａ）、（Ｂ）、（Ｃ）はそれぞれスピードナットの平面図、スピードナットの側面図、スピードナットの本発明第一実施例のスピードナット自動供給組付装置の検知器での検知位置を示す図、図４は本発明第一実施例のスピードナット自動供給組付装置の整列供給されたスピードナットをピッキングするピッキング部を拡大した斜視図、図５は本発明第一実施例のスピードナット自動供給組付装置のピッキング部の斜視図で、図６は本発明第一実施例のスピードナット自動供給組付装置のピッキング部の断面図である。 The speed nut automatic supply and assembly device of the first embodiment to which the present invention is applied will be described with reference to Figures 1 to 6. Figure 1 is a side view showing the operation state of the picking section and picking drive section of the speed nut automatic supply and assembly device of the first embodiment of the present invention. Figure 2 is a side view of the speed nut automatic supply and assembly device and the work supply section of the first embodiment of the present invention. Figures 3(A), (B), and (C) are respectively a plan view of a speed nut, a side view of a speed nut, and a view showing the detection position of the speed nut by the detector of the speed nut automatic supply and assembly device of the first embodiment of the present invention. Figure 4 is an enlarged perspective view of the picking section that picks the speed nuts that are aligned and supplied by the speed nut automatic supply and assembly device of the first embodiment of the present invention. Figure 5 is a perspective view of the picking section of the speed nut automatic supply and assembly device of the first embodiment of the present invention. Figure 6 is a cross-sectional view of the picking section of the speed nut automatic supply and assembly device of the first embodiment of the present invention.
図１及び図６に示すように本発明第一実施例のスピードナット自動供給組付装置のピッキング部１はバネで連結された２枚の板で構成され、ピッキング部を前後及び回転方向に駆動可能にするようにピッキング駆動部６に接続されている。なお、図１ではピッキング駆動部の一部を示し、駆動源は図示していない。 As shown in Figures 1 and 6, the picking section 1 of the speed nut automatic supply and assembly device of the first embodiment of the present invention is composed of two plates connected by a spring, and is connected to a picking drive section 6 so that the picking section can be driven forward and backward and in a rotational direction. Note that Figure 1 shows only a part of the picking drive section, and does not show the drive source.
また、本発明第一実施例のスピードナットのピッキング部の２枚の板は、一方の板がピッキング駆動部と反対端に切り欠き部を有し、他方の板には前記切り欠き部と重なる位置に孔を有し、ピッキング部の２枚の板のピッキング駆動部と反対側端の断面間隔はＵ字状のスピードナットの断面の最大間隔より狭いようになっている。 In addition, one of the two plates of the picking section of the speed nut in the first embodiment of the present invention has a notch at the end opposite the picking drive section, and the other plate has a hole at a position overlapping with the notch, so that the cross-sectional distance between the ends of the two plates of the picking section opposite the picking drive section is narrower than the maximum cross-sectional distance of the U-shaped speed nut.
更にこのピッキング部の板の穴位置にピッキング部内に挿入された物体となるスピードナットの存在を検知できる検知器２０を設けている。検知器２０は光を利用した光電センサやレーザーセンサ、あるいは磁性体を検知できる電磁センサを用いることができ、特に電磁センサを用いるときはピッキング部１を構成する２枚の板は非磁性材料であることが望ましい。 Furthermore, a detector 20 is provided at the hole position of the plate of the picking section, which can detect the presence of a speed nut, which is an object inserted into the picking section. The detector 20 can be a photoelectric sensor or laser sensor that uses light, or an electromagnetic sensor that can detect magnetic materials, and when using an electromagnetic sensor in particular, it is desirable that the two plates that make up the picking section 1 are made of a non-magnetic material.
図２に示す本発明第一実施例のスピードナット自動供給組付装置８およびワーク供給台１１の側面図のように、スピードナット自動供給組付装置８はスピードナットをハンドリングするピッキング部１およびピッキング部１を前後及び回転方向に駆動可能にするピッキング駆動部６およびスピードナット整列供給部となるパーツフィーダー９からなる。 As shown in FIG. 2, which is a side view of the speed nut automatic supply and assembly device 8 and work supply table 11 of the first embodiment of the present invention, the speed nut automatic supply and assembly device 8 is composed of a picking unit 1 that handles the speed nuts, a picking drive unit 6 that enables the picking unit 1 to be driven in the forward/backward and rotational directions, and a parts feeder 9 that serves as the speed nut alignment and supply unit.
図３（Ａ）および（Ｂ）に示すように、Ｕ字状に形成され、一方の舌片にネジ篏通穴を備えているスピードナットＷ１を図４で図示しないスピードナット供給部およびパーツフィーダーで図４に示すように整列供給する。 As shown in Figures 3(A) and (B), the speed nut W1 is U-shaped and has a screw hole in one of its tongues. It is aligned and supplied as shown in Figure 4 by a speed nut supply unit and a parts feeder (not shown in Figure 4).
本発明第一実施例のスピードナット自動供給組付装置は、ピッキング駆動部６を動作させることにより、ピッキング部１の２枚の板の開口部をパーツフィーダーから整列供給されてきたスピードナットの方向に向け、接近させる。ピッキング部１を構成する２枚の板のスピードナット側端は概Ｖ字形状面になっており、このＶ字状面に沿ってピッキング部１はスムーズにスピードナットＷ１に接するまで移動する。ピッキング部１にはスピードナットＷ1の落下止部１３が設けられており、ピッキング部１をどのような方向に傾けても内部に握持したスピードナットが自然落下しないようになっているので、ピッキング部１がスピードナットに接した後、更にスピードナット方向に近づこうとすると、ピッキング部１の断面に設けられたスピードナット断面形状に倣った型枠に沿ってスピードナットがピッキング部１に握持され、ピッキング部１に設けられた検知部２０が図３（Ｃ）に示すようなスピードナットの存在を確認し、確実に握持されたことがわかる。 In the speed nut automatic supply and assembly device according to the first embodiment of the present invention, the picking drive unit 6 is operated to orient the openings of the two plates of the picking unit 1 toward the speed nut that has been aligned and supplied from the parts feeder and bring them closer. The speed nut side ends of the two plates that make up the picking unit 1 are roughly V-shaped, and the picking unit 1 moves smoothly along this V-shaped surface until it comes into contact with the speed nut W1. The picking unit 1 is provided with a speed nut W1 drop prevention unit 13, so that the speed nut held inside will not fall naturally no matter what direction the picking unit 1 is tilted in. Therefore, after the picking unit 1 comes into contact with the speed nut, when it tries to move further toward the speed nut, the speed nut is held by the picking unit 1 along a mold that imitates the cross-sectional shape of the speed nut provided on the cross section of the picking unit 1, and the detection unit 20 provided on the picking unit 1 confirms the presence of the speed nut as shown in FIG. 3(C), indicating that it has been securely held.
図１にはピッキング部１がスピードナットを装着するワークＷ２方向に装着位置まで伸びて装着する様子が２点鎖線で表されている。ワークＷ２は図２に示すようにワーク供給台１１上に供給され、ワーク供給台１１に設置されているワーク検出センサ21で位置検査されて静止し、ピッキング駆動部６を作動させることによりピッキング部１がワークＷ２方向に伸びていく。 In Figure 1, the two-dot chain line shows how the picking unit 1 extends in the direction of the workpiece W2 to which the speed nut is to be attached, to the attachment position, and then attaches it. As shown in Figure 2, the workpiece W2 is supplied onto the workpiece supply table 11, its position is inspected by the workpiece detection sensor 21 installed on the workpiece supply table 11, and it stops. The picking drive unit 6 is then operated, causing the picking unit 1 to extend in the direction of the workpiece W2.
ピッキング部１を構成する２枚の板のワーク側端は概Ｖ字形状面になっており、このＶ字状面に沿ってピッキング部１はスムーズにワークＷ２に接するまで移動する。ピッキング部１にはスピードナットＷ２の落下止部１３が設けられており、ピッキング部１をどのような方向に傾けても内部に握持したスピードナットが自然落下しないようになっている。 The work side ends of the two plates that make up the picking unit 1 form a roughly V-shaped surface, and the picking unit 1 moves smoothly along this V-shaped surface until it comes into contact with the work W2. The picking unit 1 is provided with a drop prevention section 13 for the speed nut W2, so that the speed nut held inside will not fall naturally, regardless of the direction in which the picking unit 1 is tilted.
ピッキング部１の落下止部１３に接したワークＷ２はピッキング部１が更に圧入してくることにより、可動可能なピッキング部１の２枚の板を押し開け、ピッキング部１内のスピードナットＷ１に圧入され、ワークＷ２にスピードナットＷ１が握持される。 When the workpiece W2 comes into contact with the drop prevention portion 13 of the picking unit 1, the picking unit 1 presses in further, pushing open the two movable plates of the picking unit 1 and pressing the workpiece W2 into the speed nut W1 inside the picking unit 1, so that the speed nut W1 is gripped by the workpiece W2.
ピッキング駆動部６を動作させ、ピッキング部１内でスピードナットＷ１を握持したワークＷ２から、ピッキング部１を離すことにより、ワークＷ２にスピードナットＷ１を装着完了させる。このとき、検知器２０はピッキング部１内にスピードナットＷ１が残存していないことを確認している。 The picking drive unit 6 is operated to separate the picking unit 1 from the workpiece W2 that has the speed nut W1 gripped within the picking unit 1, thereby completing the attachment of the speed nut W1 to the workpiece W2. At this time, the detector 20 confirms that no speed nut W1 remains within the picking unit 1.
以上（００１６）から（００２１）を繰り返すことにより、ワークに順にスピードナットを装着できる。 By repeating steps (0016) to (0021), the speed nuts can be attached to the workpiece in sequence.
