Description

 本発明は、送り装置に係り、特に移動方向とは直角の方向に長い移動体におけるヨーイング運動を簡単な機構で規制する送り装置に関する。 The present invention relates to a feeder, and more particularly, to a feeder that regulates yawing motion of a moving body that is long in a direction perpendicular to the moving direction with a simple mechanism.

 従来の送り装置としては、例えば特開平5−92376号公報に開示されたものがある。このものは、図15に示すように、基台100上に、X軸方向へ平行に配設された1対のX軸ガイド114a,114bと、X軸方向と直角な方向へ平行に配設された1対のY軸ガイド126a,126bと、X軸方向へ配設されると共に1対のY軸ガイド126a,126b間に跨がって配設されY軸ガイド126a,126bに沿ってY軸方向へ移動可能なX軸スライダガイド130と、X軸ガイド114b,114b間に跨がって配設されX軸ガイド114a,114bに沿ってX軸方向へ移動可能なY軸スライダガイド118と、X軸スライダガイド130とY軸スライダガイド118上をX−Y方向へ移動可能なスライダ142と、スライダ142をX−Y方向へ移動させるための駆動機構134,136,138,140と、X軸スライダガイド130のX軸方向に対する傾きを規制するためのX軸規制手段およびY軸スライダガイド118のY軸方向に対する傾きを規制するためのY軸規制手段とを備えた2次元運動機構である。 As a conventional feeder, for example, there is one disclosed in Japanese Patent Application Laid-Open No. 5-92376. As shown in FIG. 15, a pair of X-axis guides 114a and 114b are provided on a base 100 in parallel with the X-axis direction, and are provided in parallel with a direction perpendicular to the X-axis direction. The pair of Y-axis guides 126a and 126b are arranged in the X-axis direction, and are arranged so as to extend between the pair of Y-axis guides 126a and 126b. An X-axis slider guide 130 movable in the axial direction; a Y-axis slider guide 118 disposed across the X-axis guides 114b and 114b and movable in the X-axis direction along the X-axis guides 114a and 114b. A slider 142 movable on the X-axis slider guide 130 and the Y-axis slider guide 118 in the XY directions, driving mechanisms 134, 136, 138, 140 for moving the slider 142 in the XY directions; Is a two-dimensional movement mechanism that includes a Y-axis regulating means for regulating the inclination with respect to the Y-axis direction of the X-axis regulating means and Y-axis slider guide 118 for regulating an inclination with respect to the X-axis direction of the slider guide 130.

 X軸規制手段は、X軸ラック112a,112b、Y軸ロッド120、そのロッド両端に取り付けたピニオンギア122a,122bを組み合わせて構成し、Y軸規制手段は、Y軸ラック124a,124b、X軸ロッド132、そのロッド両端に取り付けたピニオンギア133a,133bを組み合わせて構成して、スライダ142がX軸ロッド132およびY軸ロッド120に案内されてX−Y方向へ移動する際のヨーイング方向の回動変位を規制している。 The X-axis restricting means is configured by combining the X-axis racks 112a and 112b, the Y-axis rod 120, and the pinion gears 122a and 122b attached to both ends of the rod, and the Y-axis restricting means is the Y-axis racks 124a and 124b and the X-axis. A combination of a rod 132 and pinion gears 133a, 133b attached to both ends of the rod, the rotation in the yawing direction when the slider 142 is guided by the X-axis rod 132 and the Y-axis rod 120 and moves in the XY direction. It regulates dynamic displacement.

 しかしながら、上記従来の送り装置である2次元運動機構には、次のような問題点がある。
(1)Y軸規制手段を構成するY軸ロッド120およびX軸規制手段を構成するX軸ロッド132に重量のある部材を用いているため、それらのイナーシャが駆動機構にとって余分な負荷となる。
(2)機構が複雑で部品点数が多く、高価になる。
(3)Y軸規制手段のY軸ロッド120およびX軸規制手段のX軸ロッド132のヨーイング方向の回動変位を規制する手段としてラック・ピニオン又はタイミングベルトの代わりに平ベルトやワイヤなどを採用した場合は、Y軸ロッド120,X軸ロッド132にすべりが発生してしまい、確実に駆動動力が伝達されない。
 そこで、本発明はこのような従来の問題点に着目してなされたものであり、簡単な機構で移動体のヨーイング方向の回動を規制することが可能な送り装置を提供することを目的とする。
However, the two-dimensional motion mechanism which is the above-mentioned conventional feeder has the following problems.
(1) Since heavy members are used for the Y-axis rod 120 constituting the Y-axis regulating means and the X-axis rod 132 constituting the X-axis regulating means, their inertia becomes an extra load on the drive mechanism.
(2) The mechanism is complicated, the number of parts is large, and the cost is high.
(3) A flat belt or a wire is used instead of a rack and pinion or a timing belt as means for restricting the rotational displacement of the Y-axis rod 120 of the Y-axis restriction means and the X-axis rod 132 of the X-axis restriction means in the yawing direction. In this case, slippage occurs in the Y-axis rod 120 and the X-axis rod 132, and the driving power is not reliably transmitted.
Therefore, the present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a feeder capable of restricting rotation of a moving body in a yawing direction by a simple mechanism. I do.

A linear drive device for moving the movable body along the linear guide device, and a posture regulating means for regulating yawing motion during the movement of the moving body on a base; And four locking points disposed at both ends of the base or the moving body at intervals in the longitudinal direction of the moving body so as to lock the ends of the rope bodies; At least two direction changing mechanisms arranged on the base or the moving body at intervals in the longitudinal direction of the body, and one of the cords is provided at the locking point on one end side of the base or the moving body.

After passing through the mechanism in the opposite direction and changing direction, it is connected to and suspended from one of the locking points at the point symmetrical position, and the yawing motion of the moving body is regulated by the tension of the cords. It is assumed that.

 また、本発明の請求項2の送り装置は、X軸方向へ移動するX軸方向移動体と、該X軸方向移動体に直交してY軸方向へ移動するY軸方向移動体とを有するX−Y送り装置であって、前記各移動体の移動方向に平行に配設されて当該移動体をそれぞれ移動方向に案内する直線案内装置と、各移動体を移動方向に駆動する駆動装置と、各移動体の移動時のヨーイング運動を規制する姿勢規制手段とを備え、該姿勢規制手段は、少なくとも1本の索体と、該索体を係止するべく前記移動体の長手方向に間隔をおいて前記基台または移動体の両端部に配置した少なくとも2か所の係止点と、前記移動体の長手方向又は長手方向と直角方向に間隔をおいて前記基台または移動体に配置した少なくとも2個の方向変換機構とを有し、前記の索体は、前記係止点の一方に係止すると共に前記方向変換機構を通し方向転換させた後に他方の係止点に係止して懸け渡し、更に一方の係止点に係止すると共に前記方向変換機構を前記とは逆方向に通して方向転換させた後に他方の係止点に係止して懸け渡してあり、前記索体の張力で前記移動体のヨーイング運動を規制する構成としたことを特徴とするものである。 Further, the feeder according to claim 2 of the present invention has an X-axis direction moving body that moves in the X-axis direction, and a Y-axis direction moving body that moves in the Y-axis direction orthogonal to the X-axis direction moving body.

Is what you do.

 直線駆動装置の駆動で、移動方向と直角方向に長い移動体に推進力を加えると、移動体に加速度が生じて移動体重心には推進力に対し反対方向の慣性力が作用する。この推進力と慣性力とが一直線上にない場合、推進力と慣性力によって偶力が発生し、移動体全体が移動方向に対し水平方向に回動(ヨーイング)しようとする。このヨーイングの回動を姿勢規制手段に張設した索体が阻止して移動体の姿勢変化を規制する。 駆 動 When driving force is applied to a moving body that is long in a direction perpendicular to the moving direction by driving the linear drive device, acceleration is generated in the moving body, and an inertial force in a direction opposite to the propelling force acts on the moving body weight center. When the propulsion force and the inertia force are not on a straight line, a couple is generated by the propulsion force and the inertia force, and the entire moving body tends to rotate (yaw) in the horizontal direction with respect to the movement direction. The rope body stretched on the posture restricting means prevents the rotation of the yawing, thereby restricting the posture change of the moving body.

 以下、この発明の実施例を図面を参照して説明する。

 以上が本実施例の送り装置における移動体の送り構造である。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view showing an outline of a first embodiment of the present invention. Parallel to the base 1 are linear guide devices 2 and 3 which are a pair of linear guide mechanisms. Further, a ball screw device 4 as a single linear drive device is arranged in parallel with the linear guide devices 2 and 3. Each of the linear guide devices 2 and 3 has a slider 6 that is guided by a guide rail 5 fixed to the base 1 and that can move smoothly in the axial direction. The moving body 7 which is long in the right angle direction is mounted. Both ends of the ball screw device 4 are rotatably supported by support portions 8 and 9, and a nut 11 is screwed through a number of balls (not shown) to a screw shaft 10 attached to the base 1. The end of the moving body 7 is locked. By rotating the screw shaft in the forward and reverse directions by a motor 12 attached to one end of the screw shaft 10, the nut 11 and thus the moving body 7 move back and forth along the guide rail 5 of the linear guide device.
The above is the feed structure of the moving body in the feed device of the present embodiment.

 次に、移動体の姿勢規制手段について説明する。
 この実施例の姿勢規制手段は、2本の索体(例えばワイヤ)15,16と4個の方向変換機構17A,17B,17C,17Dを備えている。各方向変換機構17A〜17Dはいずれも同一構造で、図2に示すように基台1に立設した固定軸18にボールベアリングなどの軸受19を介して滑車20が取り付けてある。この実施例の場合、4個ともガイドレール5の端部近くにおいて基台1上に設置しほぼ点対称に配置している。
Next, the posture regulating means of the moving body will be described.
The posture restricting means of this embodiment includes two cords (for example, wires) 15, 16 and four direction changing mechanisms 17A, 17B, 17C, 17D. Each of the direction changing mechanisms 17A to 17D has the same structure, and a pulley 20 is mounted on a fixed shaft 18 erected on the base 1 via a bearing 19 such as a ball bearing as shown in FIG. In the case of this embodiment, all four are installed on the base 1 near the end of the guide rail 5 and are arranged almost point-symmetrically.

 また、移動体7の端部には、ワイヤ15,16の端部を固定する4個所の係止点22A,22B,22C,22Dが点対称に配設されている。そのうちの2箇所の係止点22C,22Dには張力調整機構23が設置してある。
 前記張力調整機構23は、図3に示すように、移動体7にボルトで固定されるL形金具24の上端部に貫通孔25を設けてボルト26を通し、L形金具24を挟むようにしてこのボルト26に螺合した2個のナット27a,27bを調整してボルト26を進退させ、又ボルト26の先端部に取り付けたワイヤ固定板28を挟むようにしてボルト26に螺合した2個のナット29a,29bを調整してワイヤ固定板28を進退させるように構成して、ワイヤ固定板28に固定したワイヤ15(16)の張力を調整するものである。
At the end of the moving body 7, four locking points 22A, 22B, 22C, 22D for fixing the ends of the wires 15, 16 are arranged point-symmetrically. A tension adjusting mechanism 23 is installed at two of the locking points 22C and 22D.
As shown in FIG. 3, the tension adjusting mechanism 23 is provided with a through-hole 25 at the upper end of an L-shaped bracket 24 fixed to the moving body 7 with bolts, passes a bolt 26, and sandwiches the L-shaped bracket 24. The two nuts 27a and 27b screwed to the bolt 26 are adjusted to move the bolt 26 forward and backward, and the two nuts 29a screwed to the bolt 26 so as to sandwich the wire fixing plate 28 attached to the tip of the bolt 26. , 29b are adjusted to move the wire fixing plate 28 forward and backward, and the tension of the wire 15 (16) fixed to the wire fixing plate 28 is adjusted.

 ワイヤ15は一端を係止点22Aに固定し、他端はまず方向変換機構17Aの滑車20に通して方向転換させた後に、移動体7の反対側に位置する方向変換機構17Bの滑車20に通して再度方向転換させ、その後に前記係止点22Aとほぼ点対称の位置にある係止点22Cに設置してある張力調整機構23に連結してZ型に懸け渡してある。
 ワイヤ16は一端を係止点22Bに固定し、他端は方向変換機構17Dの滑車20に通して方向転換させた後に、移動体7の反対側に位置する方向変換機構17Cの滑車20に通して再度方向転換させ、その後に前記係止点22Bと点対称の位置にある係止点22Dに設置してある張力調整機構23に連結して逆Z型に懸け渡してある。
One end of the wire 15 is fixed to the locking point 22A, and the other end is first turned through the pulley 20 of the direction changing mechanism 17A, and then turned to the pulley 20 of the direction changing mechanism 17B located on the opposite side of the moving body 7. After that, the direction is changed again, and after that, it is connected to a tension adjusting mechanism 23 installed at a locking point 22C substantially symmetrical with the locking point 22A, and is suspended in a Z-shape.
One end of the wire 16 is fixed to the locking point 22B, and the other end is passed through the pulley 20 of the direction changing mechanism 17D to change the direction, and then passed through the pulley 20 of the direction changing mechanism 17C located on the opposite side of the moving body 7. After that, the direction is changed again, and thereafter, it is connected to the tension adjusting mechanism 23 installed at the locking point 22D which is located symmetrically with respect to the locking point 22B, and is suspended in an inverted Z-shape.

 このように、ワイヤ15,16を方向変換機構17A〜17Dに懸け渡すときは、滑車20に巻きつけずに通すだけで方向転換させてよいが、図2に示すように1回以上滑車20に巻付けた後ワイヤ15,16の方向を転換させてもよい。
 上記の送り装置の作用を説明する。
 モータ12を一方向に駆動してボールねじ装置4のねじ軸10を回転させ、ナット11を介して移動体7に力Fを加えることにより、移動体7を矢符号Y方向に移動させる。このとき図1に示すように、ナット11と一体の移動体7(合計質量m)には加速度αが生じて重心点Gに慣性力mαが作用する。この慣性力mαと力Fとが偶力となって移動体7が図1で時計回りに回動(ヨーイング運動)しようとする。しかし、係止点22Bと係止点22Dとの間に方向変換機構17C,17Dを介して張設したワイヤ16の張力で、その時計回りのヨーイング運動は規制される。
As described above, when the wires 15 and 16 are hung over the direction change mechanisms 17A to 17D, the direction may be changed simply by passing the wires 15 and 16 without winding them around the pulley 20, but as shown in FIG. After the winding, the directions of the wires 15 and 16 may be changed.
The operation of the above-described feeding device will be described.
The motor 12 is driven in one direction to rotate the screw shaft 10 of the ball screw device 4, and a force F is applied to the moving body 7 via the nut 11, thereby moving the moving body 7 in the arrow Y direction. At this time, as shown in FIG. 1, an acceleration α is generated in the moving body 7 (total mass m) integrated with the nut 11, and an inertia force mα acts on the center of gravity G. The inertia force mα and the force F become a couple, and the moving body 7 tends to rotate clockwise in FIG. 1 (yawing movement). However, the clockwise yawing motion is restricted by the tension of the wire 16 stretched between the locking point 22B and the locking point 22D via the direction changing mechanisms 17C and 17D.

 モータ12を逆方向に回転駆動して、移動体7に力F’を加え矢符号Y’方向に移動させる場合は、ナット11と一体の移動体7(合計質量m)に加速度α’が生じて重心点Gに慣性力mα’が作用する。この慣性力mα’により移動体7が図1で反時計回りに回動しようとする。しかし、係止点22Aと係止点22CDとの間に方向変換機構17A,17Bを介して張設したワイヤ15の張力で、その反時計回りのヨーイング運動は規制される。 When the motor 12 is rotationally driven in the reverse direction to apply a force F 'to the moving body 7 and move the moving body 7 in the direction of the arrow Y', an acceleration α 'is generated in the moving body 7 (total mass m) integral with the nut 11. The inertia force mα ′ acts on the center of gravity G. The inertial force m [alpha] 'causes the moving body 7 to rotate counterclockwise in FIG. However, the counterclockwise yawing motion is restricted by the tension of the wire 15 stretched between the locking point 22A and the locking point 22CD via the direction changing mechanisms 17A and 17B.

 方向変換機構17A〜17Dに懸け渡したワイヤ15,16はいずれも両端を移動体7に固定して張設されているから、方向変換機構17A〜17Dの滑車20に巻きつけずに通しただけでも滑りを生じるおそれはなく、ヨーイング運動による移動体7の姿勢変動を確実に規制することができる。しかも、図2に示すようにワイヤ15,16を1回以上滑車20に巻付けて張設した場合には、滑りが発生しないだけでなく、移動体7が急加減速したときにはワイヤ15,16が締まり、最も近い方向変換機構17A〜17Dによって拘束されるためワイヤ剛性が高まり、移動体7のこじりが小さくなる。ためにワイヤ15,16の耐久性が大きくなる。 Since the wires 15 and 16 suspended from the direction changing mechanisms 17A to 17D are both stretched with both ends fixed to the moving body 7, the wires 15 and 16 only pass through the pulleys 20 of the direction changing mechanisms 17A to 17D without being wound. However, there is no risk of slippage, and it is possible to reliably restrict the posture change of the moving body 7 due to the yawing motion. Further, as shown in FIG. 2, when the wires 15 and 16 are wound around the pulley 20 at least once and stretched, not only does the slippage not occur, but also when the moving body 7 suddenly accelerates and decelerates. Are tightened and restrained by the closest direction change mechanisms 17A to 17D, so that the wire rigidity is increased and the twisting of the moving body 7 is reduced. Therefore, the durability of the wires 15 and 16 increases.

 この送り装置では、従来例の重いロッドなどのように移動体7の負荷イナーシャを大きく増加させるものがないから、駆動モータ12の負担が小さい。また、機構が簡単であり、安価にできる。
 図4に本発明の第2の実施例を示す。
 なお、第1の実施例と同一の構成部分には第1の実施例と同一の符号を付し、重複する説明は省略する(以下、その他の実施例においても同様である)。
In this feeder, since there is nothing to greatly increase the load inertia of the moving body 7 unlike a conventional heavy rod or the like, the load on the drive motor 12 is small. In addition, the mechanism is simple and can be made inexpensive.
FIG. 4 shows a second embodiment of the present invention.
The same components as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and duplicate description will be omitted (the same applies to other embodiments).

One end of the wire 15 is fixed to the locking point 22A, and the other end is first passed through one pulley 20 of the double direction change mechanism 30A to change the direction, and then the double type is positioned on the opposite side of the moving body 7. The direction is changed again through one of the pulleys 20 of the direction changing mechanism 30B, and is connected to a tension adjusting mechanism 23 installed at the locking point 22C and is hung in a Z-shape.

 この実施例は第1の実施例の方向変換機構の17Aと17Cとを一個所にまとめて二連式方向変換機構30Aとし、また、第1の実施例の方向変換機構の17Bと17Dとを一個所にまとめて二連式方向変換機構30Bとしたのであり、作用・効果は第1実施例と同じである。
 図5に本発明の第3の実施例を示す。
 この実施例の姿勢規制手段は、2本のワイヤ15,16と、基台1の4コーナ部に配設した4個の方向変換機構17A,17B,17C,17Dを備えている点は図1のものと同様であるが、更に移動体7上に長手方向に間隔をおいて配設した2個の方向変換機構17E,17Fを備えている点が異なる。
In this embodiment, the direction changing mechanisms 17A and 17C of the first embodiment are combined into a single location to form a dual direction changing mechanism 30A, and the direction changing mechanisms 17B and 17D of the first embodiment are combined with each other. The double direction changing mechanism 30B is integrated into one place, and the operation and effect are the same as those of the first embodiment.
FIG. 5 shows a third embodiment of the present invention.
The position regulating means of this embodiment is provided with two wires 15 and 16 and four direction changing mechanisms 17A, 17B, 17C and 17D provided at four corners of the base 1 in FIG. , Except that two direction changing mechanisms 17E and 17F are further provided on the moving body 7 at intervals in the longitudinal direction.

 ワイヤ15は一端を係止点22Aに固定し、他端はまず方向変換機構17Aを通して反対方向に180度方向変換した後に、移動体7上にある方向変換機構17Eに通して横方向に方向転換させ、移動体7上を経て他の方向変換機構17Fに通して下方向に方向転換させ、そのご方向変換機構17Bに通して更に180度方向変換した後に、係止点22Cに設置してある張力調整機構23に連結して懸け渡してある。 One end of the wire 15 is fixed to the locking point 22A, and the other end is first turned 180 degrees in the opposite direction through the direction changing mechanism 17A, and then turned laterally through the direction changing mechanism 17E on the moving body 7. Then, after passing through the moving body 7 and passing through another direction changing mechanism 17F, the direction is changed downward, and the direction is further changed by 180 degrees through the direction changing mechanism 17B. It is connected to the tension adjusting mechanism 23 and suspended.

 ワイヤ16は一端を係止点22Bに固定し、他端はまず方向変換機構17Dを通して反対方向に180度方向変換した後に、移動体7上にある方向変換機構17Eに通して横方向に方向転換させ、移動体7上を経て他の方向変換機構17Fに通して上方向に方向転換させ、その後方向変換機構17Cに通して更に180度方向変換した後に、係止点22Dに設置してある張力調整機構23に連結して懸け渡してある。 One end of the wire 16 is fixed to the locking point 22B, and the other end is first turned 180 degrees in the opposite direction through the direction changing mechanism 17D, and then turned laterally through the direction changing mechanism 17E on the moving body 7. After passing through the moving body 7 and passing through the other direction changing mechanism 17F to change the direction upward, and then passing through the direction changing mechanism 17C to further change the direction by 180 degrees, the tension set at the locking point 22D is set. It is connected to the adjusting mechanism 23 and suspended.

 この場合、移動体7上に設置してある方向変換機構17E,17Fの滑車は例えば図2に示す滑車20と同じでよい。その滑車にはワイヤ15および16の両方を逆巻きに通してあり、一つの滑車で同時に両方のワイヤ15,16を反対向きに方向変換させることになるが、両ワイヤ15,16共に、滑車の回転方向と同一となるため差し支えない。ワイヤ15は移動体7の反時計回りの回動運動を規制し、ワイヤ16は時計回りの回動運動を規制する。
 この第3の実施例によれば、ワイヤ15,16はリニアガイド装置のガイドレール5沿い及び移動体7上のみを通り送り装置の幅方向中央部は通らないから、装置中央部の全体を作業領域として確保することができ、また中央部に他機構が設置されてもワイヤとの干渉が発生しないという利点がある。
 図6に本発明の第4の実施例を示す。
In this case, the pulleys of the direction changing mechanisms 17E and 17F installed on the moving body 7 may be the same as, for example, the pulley 20 shown in FIG. The pulley has both wires 15 and 16 wound in opposite turns, and one pulley will simultaneously turn both wires 15 and 16 in opposite directions, but both wires 15 and 16 both rotate the pulley. Since it is the same as the direction, there is no problem. The wire 15 regulates the counterclockwise rotation of the moving body 7, and the wire 16 restricts the clockwise rotation.
According to the third embodiment, since the wires 15 and 16 pass only along the guide rail 5 of the linear guide device and on the moving body 7 and do not pass through the central portion in the width direction of the feeding device, the entire central portion of the device is worked. There is an advantage that it can be secured as an area, and even if another mechanism is installed in the center, interference with the wire does not occur.
FIG. 6 shows a fourth embodiment of the present invention.

 この実施例の姿勢規制手段は、2本のワイヤ15,16と、基台1の一端側の左右のコーナ部に配設した2個の方向変換機構17A,17Cと、基台1の他端側の左右のコーナ部に配設した2個の二連式方向変換機構30A,30Bを備えている。
 ワイヤ15は一端を係止点22Aに固定し、他端はまず方向変換機構17Aを通して反対方向に180度方向変換した後に、移動体7の下を通り反対側の二連式方向変換機構30Aの一方の滑車で横に方向転換させてそのまま延ばし、対向コーナにある二連式方向変換機構30Bの一方の滑車で上向きに方向転換させた後に係止点22Cに設置してある張力調整機構23に連結して懸け渡してある。
The posture restricting means of this embodiment includes two wires 15 and 16, two direction change mechanisms 17 A and 17 C disposed at left and right corners on one end side of the base 1, and the other end of the base 1. There are provided two double direction changing mechanisms 30A and 30B arranged at the left and right corners of the side.
One end of the wire 15 is fixed to the locking point 22A, and the other end of the wire 15 is first turned 180 degrees in the opposite direction through the direction changing mechanism 17A, and then passes under the moving body 7 to be connected to the opposite double direction changing mechanism 30A. The pulley is turned sideways by one pulley and extended as it is. After turning upward by one pulley of the dual direction change mechanism 30B at the opposite corner, the tension is adjusted to the tension adjusting mechanism 23 installed at the locking point 22C. It is connected and suspended.

 ワイヤ16は一端を係止点22Bに固定し、他端はまず下方の二連式方向変換機構30Aの他方の滑車で横に方向転換させてからワイヤ15と平行にそのまま横に延ばし、対向コーナにある二連式方向変換機構30Bの他方の滑車で上向きに方向転換させた後に、移動体7の下を通り反対側の方向変換機構17Cに通して反対方向に180度方向変換させ、その後係止点22Dに設置してある張力調整機構23に連結して懸け渡してある。 One end of the wire 16 is fixed to the locking point 22B, and the other end is first turned sideways by the other pulley of the lower two-way turning mechanism 30A, and then extends horizontally in parallel with the wire 15 so as to extend in the opposite corner. After turning upward with the other pulley of the dual-type turning mechanism 30B, the vehicle passes under the moving body 7 and passes through the turning mechanism 17C on the opposite side to turn 180 degrees in the opposite direction. It is connected to and suspended from a tension adjusting mechanism 23 installed at a stop point 22D.

 ワイヤ15は移動体7の反時計回りの回動運動を規制し、ワイヤ16は時計回りの回動運動を規制する。
 この第4の実施例によれば、ワイヤ15,16は基台1の3辺沿いを通るように懸け渡してあるため、装置中央部は移動体7の移動範囲の全域を作業領域として確保できる。また、中央部に他の機構が設置されてもワイヤとの干渉が生じない。また、移動体7の上をワイヤが通らないため、移動体7上に設置された他の機構との干渉も生じない等の利点がある。
The wire 15 regulates the counterclockwise rotation of the moving body 7, and the wire 16 restricts the clockwise rotation.
According to the fourth embodiment, since the wires 15 and 16 are suspended along the three sides of the base 1, the entire area of the moving range of the moving body 7 can be secured as a work area at the center of the apparatus. . Also, even if another mechanism is installed at the center, interference with the wire does not occur. In addition, since the wire does not pass over the moving body 7, there is an advantage that interference with other mechanisms installed on the moving body 7 does not occur.

 図7に本発明の第5の実施例を示す。
 この実施例の姿勢規制手段は、2本のワイヤ15,16の係止点22A,22B,22C,22Dが基台1のコーナ部に点対称に配設されている。また、2個の方向変換機構17E,17Fが図5の場合と同じく移動体7の上に配設されている。
 ワイヤ15は一端を係止点22Aに固定し、他端はまず移動体7上にある方向変換機構17Eに通して横方向に方向転換させ、移動体7上を経て他の方向変換機構17Fに通して下方向に方向転換した後に、係止点22Cに設置してある張力調整機構23に連結して懸け渡してある。
FIG. 7 shows a fifth embodiment of the present invention.
In the posture restricting means of this embodiment, the locking points 22A, 22B, 22C, 22D of the two wires 15, 16 are arranged point-symmetrically at the corners of the base 1. Also, two direction changing mechanisms 17E and 17F are arranged on the moving body 7 as in the case of FIG.
One end of the wire 15 is fixed to the locking point 22A, and the other end is first turned laterally through a direction changing mechanism 17E on the moving body 7, and then to another direction changing mechanism 17F via the moving body 7. After passing through and turning in the downward direction, it is connected to and suspended from a tension adjusting mechanism 23 installed at the locking point 22C.

 ワイヤ16は一端を係止点22Bに固定し、他端はまず移動体7上にある方向変換機構17Eにワイヤ15とは逆巻きに通して横方向に方向転換させ、移動体7上を経て他の方向変換機構17Fにワイヤ15とは逆巻きに通して上方向に方向転換した後に、係止点22Dに設置してある張力調整機構23に連結して懸け渡してある。
 ワイヤ15は移動体7の反時計回りの回動運動を規制し、ワイヤ16は時計回りの回動運動を規制する。
 この第5の実施例によれば、ワイヤ15,16はリニアガイド装置のガイドレール5沿い及び移動体7上のみを通るため、装置の移動体移動方向の両端部が作業領域として利用できる。
One end of the wire 16 is fixed to the locking point 22B, and the other end is first turned to the direction changing mechanism 17E on the moving body 7 in the reverse direction to the wire 15 so as to change its direction in the horizontal direction, and then passes through the moving body 7 to the other direction. After passing through the direction changing mechanism 17F in the reverse winding direction with respect to the wire 15 to change the direction upward, it is connected to and suspended from a tension adjusting mechanism 23 installed at the locking point 22D.
The wire 15 regulates the counterclockwise rotation of the moving body 7, and the wire 16 restricts the clockwise rotation.
According to the fifth embodiment, since the wires 15 and 16 pass only along the guide rail 5 of the linear guide device and on the moving body 7, both ends of the apparatus in the moving direction of the moving body can be used as working areas.

 この第6の実施例のX−Y送り装置は、X−Yの2軸方向に広い作業領域を確保しつつ、二つの移動体7X,7Yのヨーイング方向の運動を規制できる利点がある。
 なお、上記各実施例では索体としてワイヤを用いた場合を説明したが、これに限らず、平ベルト,チエーン,コイルばね等を用いても良い。
 また、移動体を直線移動させる直線駆動装置としてはボールねじ装置を用いた場合を説明したが、その他の直線駆動装置であるタイミングベルト送り機構やラックアンドピニオン送り機構を用いることもできる。
The XY feeder according to the sixth embodiment has an advantage that the movement of the two moving bodies 7X and 7Y in the yawing direction can be restricted while securing a wide working area in the XY biaxial directions.
In each of the above embodiments, the case where a wire is used as the cord is described. However, the present invention is not limited to this, and a flat belt, a chain, a coil spring, or the like may be used.
Also, a case has been described in which a ball screw device is used as the linear drive device for linearly moving the moving body. However, other linear drive devices such as a timing belt feed mechanism and a rack and pinion feed mechanism can also be used.

 また、張力調整機構についても、図3に示した構造に限定するものではなく、その他バネを組み込んだものでも良い。
 また、各実施例ではワイヤを2本使用した例を示したが、例えば移動体の張力調整機構23の設置してない係止点22A,22B間にワイヤを通した上で22A,22Bで固定(この場合一つの係止点だけでも可)して1本のワイヤとすることもできる。
 更にまた、ワイヤは同じ経路を1本のワイヤで数往復しても良く、また同じ経路に複数本のワイヤを通しても良い。このようにすることによって、ヨーイング方向の規制のためワイヤの剛性が向上する。
 また、第1の実施例のみならず、第2〜第6の実施例においても、ワイヤを方向転換機構に懸け渡すときに、1回以上滑車20に巻き付けた後、ワイヤの方向を転換させても良い。
Further, the tension adjusting mechanism is not limited to the structure shown in FIG. 3, but may be a mechanism incorporating a spring.
In each embodiment, two wires are used. However, for example, a wire is passed between the locking points 22A and 22B where the tension adjusting mechanism 23 of the moving body is not installed, and the wires are fixed at 22A and 22B. (In this case, only one locking point is possible.)
Furthermore, the wire may make several reciprocations on the same path with one wire, or may pass a plurality of wires through the same path. By doing so, the rigidity of the wire is improved due to the restriction in the yawing direction.
In addition to the first embodiment, in the second to sixth embodiments, when the wire is wound around the pulley 20 at least once when the wire is hung over the direction change mechanism, the direction of the wire is changed. Is also good.
