Description

【０００１】
【発明の属する技術分野】
本発明は、例えばシャープペンシル本体先端部の雄ねじに雌ねじが形成された先部材を螺合するようにした仮締め装置に関する。
【０００２】
【従来の技術】
従来、シャープペンシルの先部材を供給ユニットより仮締めユニットに切り出し、バキュームにより保持し、順次間歇移送されるシャープペンシルに本体の先端に形成された雄ねじに螺合する場合、仮締めユニットを回転して前記先部材をシャープペンシルの本体と同軸に位置させ、次いで、回転させながら仮締めユニットを前進させ螺合していた。
【０００３】
【発明が解決しようとする課題】
上記従来技術は、先部材の雌ねじや本体先端部の雄ねじにバラツキがあったり、ねじの切り方にバラツキがあった場合でもバキュームにより保持したまゝ前進・回転するのでねじ山がくずれたり、又は螺合できないことがあった。
【０００４】
【課題を解決するための手段】
本発明は上記問題点を解決することを目的とし、一方のねじ部材を一定位置に固定し、他方のねじ部材を仮締めユニットにバキュームにより保持し、該仮締めユニットを前進させ螺合直前で前記バキュームを止めブローに切り換え、前記他方のねじ部材を先方に飛ばす手段を有することを特徴とする。
【０００５】
【発明の実施の形態】
本発明の実施の形態を図示した一実施例に基づいて詳細に説明する。
図１乃至図５は本発明の第１実施例である。１は一定間隔でシャープペンシル本体を配設し、間歇前進するワーク搬送装置である。３は先部材４の供給ユニット、６は先部材４をバキュームにより吸着する仮締めユニットで、回転テーブル５上に配設され、カムロッド１８により前進するようになっている。８は仮締めユニット６に固定されたギヤーで、所定位置でモータ７で駆動されるギヤー９と噛合するようになっている。１０はインデックスである。
【０００６】
次に作用について説明する。
図１の状態で回転テーブル５停止中、先部材供給ユニット３より先部材４が上方位置にある第１の仮締めユニット６に吸着されており、右側の水平位置にある第２の仮締めユニット６はワーク２と同一軸に沿って位置している。この状態でインデックス１０を作動して回転テーブル５を１／４右回転させる。第２の仮締めユニット６はカム駆動により前進し、この途中で仮締めユニット６のギヤー８がモータ７のギヤー９と噛合し、前進し乍ら回転を行う。先部材４先端がワーク２に螺合が開始される直前で真空による吸着を止め、同じ空気孔を利用してエアーブローを行い先部材４を吹き飛ばす。吹き飛ばされた先部材４は径方向に自由になっているので回転し乍らワーク２に対して自動調芯を行い円滑に螺合が行われ、噛み込むことがない。
なお、シャープペンシル本体に先部材を螺合する代りに、他の雄ねじに雌ねじを螺合する場合にも適用できる。
【０００７】
図６は本発明の第２実施例である。１１は容器のキャップ螺合部で、搬送装置１２の上に一列に載置され間歇移送される。１３はモータで、モータ軸１４先端に当接したキャップ１５は吸着具１６により吸着され、モータ１３で回転している。１７は１軸ロボットである。
【０００８】
次に作用について説明する。
容器のキャップ締めの際、回転し乍ら吸着されたキャップ１５を１軸ロボット１７によって下降させ、容器のキャップ螺合部１１とキャップ１５の螺合が始まる寸前にエアーブローし、吹き飛ばされたキャップは自ら回転し乍ら容器のキャップ螺合部１１に合致するよう自動調芯をし、円滑に螺合を行い仮締めする。
【０００９】
【発明の効果】
本発明は、一方のねじ部材を一定位置に固定し、他方のねじ部材を仮締めユニットにバキュームにより保持し、該仮締めユニットを前進させ螺合直前で前記バキュームを止めブローに切り換え、前記他方のねじ部材を先方に飛ばす手段を有してあるので、部品のバラツキ、２つのねじ部材の取り付け誤差があっても、先部材は径方向自由に動き得るようになっているので、自動調芯が行われ、かじることなく螺合を正確に行い仮締めすることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a temporary fastening device in which, for example, a tip member in which a female screw is formed is screwed to a male screw at a tip of a mechanical pencil body.
[0002]
[Prior art]
Conventionally, when the mechanical pencil tip member is cut out from the supply unit into the temporary fastening unit, held by vacuum, and then mechanically transferred to the mechanical pencil, the temporary fastening unit is rotated. The tip member is positioned coaxially with the main body of the mechanical pencil, and then the temporary fastening unit is advanced and screwed while rotating.
[0003]
[Problems to be solved by the invention]
In the above prior art, even if there is a variation in the internal thread of the tip member or the external thread of the main body, or even if there is a variation in the cutting method of the screw, the screw thread is broken because it advances and rotates while being held by the vacuum, or Sometimes it could not be screwed.
[0004]
[Means for Solving the Problems]
An object of the present invention is to solve the above-described problems. One screw member is fixed at a fixed position, the other screw member is held in a temporary fastening unit by a vacuum, and the temporary fastening unit is advanced and immediately before screwing. The vacuum is stopped and switched to blow, and the other screw member is moved forward.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described in detail based on an illustrated example.
1 to 5 show a first embodiment of the present invention. Reference numeral 1 denotes a workpiece transfer device in which mechanical pencil main bodies are arranged at regular intervals and move forward intermittently. Reference numeral 3 denotes a supply unit for the tip member 4, and reference numeral 6 denotes a temporary fastening unit that sucks the tip member 4 by vacuum. A gear 8 is fixed to the temporary fastening unit 6 and meshes with a gear 9 driven by a motor 7 at a predetermined position. 10 is an index.
[0006]
Next, the operation will be described.
When the rotary table 5 is stopped in the state of FIG. 1, the tip member 4 is attracted to the first temporary fastening unit 6 located at the upper position from the leading member supply unit 3, and the second temporary fastening unit located at the right horizontal position. 6 is located along the same axis as the workpiece 2. In this state, the index 10 is operated to rotate the turntable 5 by 1/4 right. The second temporary fastening unit 6 moves forward by cam drive, and the gear 8 of the temporary fastening unit 6 meshes with the gear 9 of the motor 7 in the middle, and rotates while moving forward. Immediately before the tip of the front member 4 starts to be screwed onto the work 2, suction by vacuum is stopped, and air blow is performed using the same air hole to blow off the front member 4. Since the blown-off tip member 4 is free in the radial direction, it automatically rotates with respect to the work 2 while rotating, and is smoothly screwed and does not bite.
In addition, instead of screwing the tip member into the mechanical pencil body, the present invention can be applied to a case where a female screw is screwed into another male screw.
[0007]
FIG. 6 shows a second embodiment of the present invention. Reference numeral 11 denotes a cap screwing portion of the container, which is placed in a row on the transport device 12 and is intermittently transferred. Reference numeral 13 denotes a motor, and a cap 15 that is in contact with the tip of the motor shaft 14 is adsorbed by an adsorber 16 and is rotated by the motor 13. Reference numeral 17 denotes a single-axis robot.
[0008]
Next, the operation will be described.
When the container cap is tightened, the cap 15 sucked while rotating is lowered by the single-axis robot 17, and air blow is performed just before the cap screwing portion 11 of the container and the cap 15 start to be screwed, and the cap blown off. is a self-aligning to conform to the threaded portion 11 of its own rotation乍Ra vessel is temporarily tightened smoothly it has rows screwing.
[0009]
【The invention's effect】
According to the present invention, one screw member is fixed at a fixed position, the other screw member is held in a temporary fastening unit by vacuum, the temporary fastening unit is advanced, and the vacuum is stopped and blown immediately before screwing, Since there is a means to skip the screw member forward, the tip member can move freely in the radial direction even if there is a variation in parts or an error in mounting the two screw members. been conducted, it is possible to temporarily tighten had accurately line the screwing without gnawing.
