By being urged to the back side of 115, the drop off from the locking groove 115 is prevented.

図７は、搬送具の箱状部を略水平に配置した状態を示す図であり、図８は、箱状部を略垂直に配置した状態を示す図である。 FIG. 7 is a diagram illustrating a state in which the box-shaped portions of the transporting tool are disposed substantially horizontally, and FIG. 8 is a diagram illustrating a state in which the box-shaped portions are disposed substantially vertically.

図５の状態から、ガイド棒１３１を支持片９９の下側の係止溝１１５から外して上方へ引き上げ、図７に示すように、上側の係止溝１１３へはめ込むことで、保持部材９３は、ほぼ水平な状態で支持部材９１に保持され、箱状部１１９の開口部は上方へ向けられる。この際、コイルバネ１３５の付勢力によりガイド棒１３１の係止溝１１３からの脱落が防止される。
さらに、ガイド棒１３１をどの係止溝１１３，１１５にもはめ込まず、図８に示すように、支持片９９の長穴１１１の下端部に配置させると、保持部材９３は、ほぼ垂直な状態で支持部材９１に保持され、箱状部１１９の開口部は、手前側（図８において左側）へ向けられる。 From the state of FIG. 5, the guide bar 131 is removed from the lower locking groove 115 of the support piece 99 and pulled upward, and is fitted into the upper locking groove 113 as shown in FIG. The support member 91 is held in a substantially horizontal state, and the opening of the box-shaped portion 119 is directed upward. At this time, the urging force of the coil spring 135 prevents the guide bar 131 from falling off the locking groove 113.
Further, when the guide bar 131 is not inserted into any of the locking grooves 113 and 115 and is arranged at the lower end portion of the elongated hole 111 of the support piece 99 as shown in FIG. 8, the holding member 93 is in a substantially vertical state. The opening of the box-shaped part 119 is held by the support member 91 and is directed toward the front side (left side in FIG. 8).

本実施例では、搬送具７が、直線状の走行路を移動する際には、図６に示すように、リンク６５は左右方向に沿って一列に配置されており、ピン１０５は、取付片９７の長穴９７ｂの左端部に配置される。 In the present embodiment, when the transport tool 7 moves on a straight traveling path, the links 65 are arranged in a line along the left-right direction as shown in FIG. 97 is disposed at the left end of the elongated hole 97b.

図９は、搬送具が第二レールの湾曲部を移動している状態を示す概略平面図である。 FIG. 9 is a schematic plan view showing a state in which the transport tool is moving along the curved portion of the second rail.

そして、搬送具７が、第二レール１１の湾曲部１１ｃを移動する際には、クレセントチェーン５が湾曲することで、図９に示すように、ピン１０３，１０５同士の距離が縮まる。しかしながら、ピン１０５が、取付片９７の長穴９７ｂの右端部へ移動することで、湾曲部１１ｃにおいても搬送具７がスムーズに移動する。同様に、第三レール１３のコーナー部においても搬送具７はスムーズに移動する。 And when the conveyance tool 7 moves the curved part 11c of the 2nd rail 11, as shown in FIG. 9, the distance between pins 103 and 105 shrinks because the crescent chain 5 curves. However, when the pin 105 moves to the right end portion of the long hole 97b of the attachment piece 97, the transport tool 7 moves smoothly even in the curved portion 11c. Similarly, the transport tool 7 moves smoothly also at the corner portion of the third rail 13.

なお、本実施例では、前記各連結片３７に、棒状の脚部Ｌの上端部が接続されて、フレーム３は脚部Ｌに保持される。 In this embodiment, the upper ends of the rod-shaped leg portions L are connected to the connecting pieces 37, and the frame 3 is held by the leg portions L.

本実施例の搬送装置１は、その用途を特に問わないが、例えば縫製工場で使用される場合、図１に示すように、各第二レール１１の湾曲部１１ｃに近接してミシンＳ１〜Ｓ３が配置され、各ミシンに作業者Ｍ１〜Ｍ３が配置される。
そして、クレセントチェーン５により搬送具７が移動し、左側の第三レール１３Ｂの位置において、略水平に配置された箱状部１１９に布片が載置された後、箱状部が約４５度に傾けられる。なお、箱状部１１９には、４種類の布片が載置されるとする。
左端の作業者Ｍ１は、移動してきた搬送具７の箱状部１１９から、一つ目の布片と二つ目の布片を取り出して、ミシンＳ１で縫い合わせ、同じ箱状部１１９に戻す。 The transport device 1 of the present embodiment is not particularly limited in its application. For example, when used in a garment factory, as shown in FIG. 1, the sewing machines S 1 to S 3 come close to the curved portion 11 c of each second rail 11. Are arranged, and workers M1 to M3 are arranged in each sewing machine.
Then, after the transport tool 7 is moved by the crescent chain 5 and the piece of cloth is placed on the box-shaped part 119 disposed substantially horizontally at the position of the left third rail 13B, the box-shaped part is about 45 degrees. Be inclined to. It is assumed that four types of cloth pieces are placed on the box-shaped portion 119.
The worker M1 at the left end takes out the first piece of cloth and the second piece of cloth from the box-like part 119 of the transporting tool 7 that has moved, sews it with the sewing machine S1, and returns it to the same box-like part 119.

次の中央の作業者Ｍ２は、左端の作業者Ｍ１が縫い合わせた物と、三つ目の布片とを取り出してミシンＳ２で縫い合わせ、同じ箱状部１１９に戻す。
また、右端の作業者Ｍ３は、中央の作業者Ｍ２が縫い合わせた物と、四つ目の布片とを箱状部１１９から取り出してミシンＳ３で縫い合わせて製品を完成させ、同じ箱状部１１９に戻す。
そして、右側の第三レール１３Ａの位置において、箱状部１１９から製品が取り出され、箱状部１１９が略垂直に配置されて、搬送具７は復路を移動し、左側の第三レール１３Ｂの位置において、箱状部１１９が水平に配置されて、上記と同様の作業が繰り返される。 The next center worker M2 takes out the thing stitched by the worker M1 at the left end and the third cloth piece, sews them together with the sewing machine S2, and returns them to the same box-shaped portion 119.
The worker M3 at the right end takes out the thing stitched by the worker M2 at the center and the fourth piece of cloth from the box-shaped part 119 and sews them with the sewing machine S3 to complete the product, and the same box-shaped part 119 is obtained. Return to.
Then, at the position of the right third rail 13A, the product is taken out from the box-shaped portion 119, the box-shaped portion 119 is arranged substantially vertically, the transporting tool 7 moves in the return path, and the left third rail 13B At the position, the box-shaped portion 119 is horizontally disposed, and the same operation as described above is repeated.

このように、本実施例の搬送装置１によれば、流れ作業で製品を縫製することができ、時間の短縮および人員を削減することが可能となる。
また、本実施例では、箱状部１１９の傾斜角度を変更可能としており、作業者が作業し易い角度で作業することができる。さらに、復路において箱状部１１９を垂直に配置しておくことで、往路と復路との間隔が狭い場合でも、箱状部１１９，１１９同士が接触することがない。
また、本実施例では、支持部材９１が複数のリンクにまたがって配置されることで、保持部材９３が大きくなった場合でも、安定して搬送することができる。 Thus, according to the conveying apparatus 1 of a present Example, a product can be sewn by a flow operation, and it becomes possible to shorten time and a staff.
In the present embodiment, the inclination angle of the box-shaped portion 119 can be changed, and the operator can work at an angle at which the operator can easily work. Furthermore, by arranging the box-shaped part 119 vertically on the return path, the box-shaped parts 119 and 119 do not contact each other even when the distance between the forward path and the return path is narrow.
Further, in the present embodiment, the support member 91 is arranged across a plurality of links, so that even when the holding member 93 becomes large, it can be stably conveyed.

さらに、本実施例では、クレセントチェーン５の走行速度を比較的遅く設定しており、各作業者が、箱状部１１９から布片を取り出し、縫い終わった後に同じ箱状部１１９に戻すことができる速度とされる。また、第二レール１１の湾曲部１１ｃを搬送具７が走行することで、上記各作業者の近傍を箱状部１１９が通過する時間が長くなり、作業者は布片を取り出した箱状部１１９と同じ箱状部１１９に縫い終わった物を戻すことができる。
本実施例では、第二レール１１は、その直線部１１ａ，１１ｂの溝ｒの前後方向中央部と、直線部１１ａ，１１ｂから最も離間した湾曲部１１ｃの溝ｒの前後方向中央部との直線距離ｘ（図２参照）が、２０ｃｍ〜８０ｃｍ程度に設定され、より好ましくは３０ｃｍ〜５０ｃｍに設定される。 Furthermore, in this embodiment, the traveling speed of the crescent chain 5 is set to be relatively slow, and each worker can take out the piece of cloth from the box-shaped part 119 and return it to the same box-shaped part 119 after sewing is completed. It is supposed to be as fast as possible. In addition, since the transport tool 7 travels on the curved portion 11c of the second rail 11, the time for the box-like portion 119 to pass in the vicinity of each operator is increased, and the operator takes out the cloth piece. What has been sewn can be returned to the same box-shaped part 119 as 119.

取付軸１５７は、その左端部が誘導板１５５の屈曲部に固定され、右端部には、周方向に沿って環状の溝１５７ａが形成されている。
また、取付軸１５７の左端部には、径方向外側へ拡径してツバ部１５９が形成されている。 The left end portion of the mounting shaft 157 is fixed to the bent portion of the guide plate 155, and an annular groove 157a is formed along the circumferential direction at the right end portion.
Further, a flange portion 159 is formed at the left end portion of the mounting shaft 157 so as to increase in diameter radially outward.

取付軸１５７は、その右端部が取付部１５３の他片１５３ｂに左右方向に沿って回転可能にはめ込まれ、ワッシャ１６１が通された後、環状溝１５７ａにＥリング１６３がはめ込まれる。これにより、取付軸１５７の左右方向の移動が規制され、誘導部材１５１が取付部１５３に取付軸１５７まわりに回転可能に保持される。 The mounting shaft 157 is fitted at the right end thereof to the other piece 153b of the mounting portion 153 so as to be rotatable in the left-right direction. After the washer 161 is passed, the E-ring 163 is fitted into the annular groove 157a. Thereby, the movement of the mounting shaft 157 in the left-right direction is restricted, and the guide member 151 is held by the mounting portion 153 so as to be rotatable around the mounting shaft 157.

また、誘導板１５５の上片１５５ａには、コイルバネ１６５の一端部が取り付けられており、このコイルバネ１６５の他端部は取付部１５３の一片１５３ａに取り付けられている。これにより、誘導板１５５は、その上片１５５ａが取付軸１５７まわりに奥側（図１１において右側）へ付勢され、上片１５５ａは係止溝１１３，１１５の上辺１１３ｂ，１１５ｂに当接しており、図１１において時計方向への一定以上の回転が規制されている。
また、この状態では、誘導板１５５は、その上片１５５ａがほぼ垂直に配置され、下片１５５ｂが手前側へ行くに従って下方へ傾斜して配置されている。 One end of a coil spring 165 is attached to the upper piece 155 a of the guide plate 155, and the other end of the coil spring 165 is attached to one piece 153 a of the attachment portion 153. As a result, the upper piece 155a of the guide plate 155 is urged to the back side (right side in FIG. 11) around the mounting shaft 157, and the upper piece 155a comes into contact with the upper sides 113b and 115b of the locking grooves 113 and 115. In FIG. 11, the rotation more than a certain amount in the clockwise direction is restricted.
Further, in this state, the guide plate 155 is arranged such that the upper piece 155a is arranged substantially vertically and the lower piece 155b is inclined downward as going to the near side.

このように誘導部材１５１が設けられている場合、ガイド棒１３１が支持片９９の長穴１１１の下端部に配置された状態から、保持部材９３を支持部材９１に対して第一軸１２５まわりに揺動させて、ガイド棒１３１を引き上げていくと、ガイド棒１３１の先端部が、誘導板１５５の傾斜した下片１５５ｂに当接することで、係止溝１１５側へ誘導され、係止溝１１５内へ突入し、ガイド棒１３１の先端部は係止溝１１５内に配置される。 When the guide member 151 is provided in this way, the holding member 93 is moved around the first shaft 125 with respect to the support member 91 from the state where the guide bar 131 is disposed at the lower end portion of the elongated hole 111 of the support piece 99. When the guide bar 131 is pulled up by swinging, the tip end portion of the guide bar 131 abuts on the inclined lower piece 155 b of the guide plate 155, and is guided to the locking groove 115 side. The tip of the guide bar 131 is disposed in the locking groove 115.

また、さらにガイド棒１３１を引き上げると、ガイド棒１３１は、誘導板１５５の上片１５５ａに当接し、誘導板１５５はコイルバネ１６５の付勢力に対抗して取付軸１５７まわりに、図１１において反時計方向に回転して、ガイド棒１３１は上方へ移動する。
そして、上記と同様に、ガイド棒１３１は、誘導板１５５の下片１５５ｂに当接して、係止溝１１３側へ誘導され、係止溝１１３内へ突入して、ガイド棒１３１の先端部は係止溝１１３内に配置される。 Further, when the guide bar 131 is further pulled up, the guide bar 131 comes into contact with the upper piece 155a of the guide plate 155, and the guide plate 155 counters the urging force of the coil spring 165 around the mounting shaft 157 in FIG. Rotating in the direction, the guide bar 131 moves upward.
Similarly to the above, the guide bar 131 abuts on the lower piece 155b of the guide plate 155, is guided to the locking groove 113 side, enters into the locking groove 113, and the tip of the guide bar 131 is It is disposed in the locking groove 113.

ガイド棒１３１の先端部が係止溝１１３内に配置された状態からガイド棒１３１を下げる際には、一旦ガイド棒１３１を上方へ引き上げて、上記と同様に誘導板１５５の上片１５５ａを図１１において反時計方向に回転させて長穴１１１の上端部にガイド棒１３１の先端部を配置し、そのまま下降させていけばよい。
この際、ガイド棒１３１の先端部は、誘導板１５５の下片１５５ｂに当接し、誘導板１５５は、コイルバネ１６５の付勢力に対抗して取付軸１５７まわりに、図１１において反時計方向に回転して、ガイド棒１３１は下方への移動が可能となる。 When the guide bar 131 is lowered from the state in which the distal end portion of the guide bar 131 is disposed in the locking groove 113, the guide bar 131 is once lifted upward, and the upper piece 155a of the guide plate 155 is illustrated in the same manner as described above. 11, the tip end of the guide bar 131 is disposed at the upper end of the elongated hole 111 by rotating it counterclockwise, and then lowered.
At this time, the distal end portion of the guide bar 131 contacts the lower piece 155b of the guide plate 155, and the guide plate 155 rotates counterclockwise in FIG. 11 around the mounting shaft 157 against the biasing force of the coil spring 165. Thus, the guide bar 131 can be moved downward.

このように、ガイド棒１３１の先端部は、上方へ移動する際には、誘導板１５５の奥側（図１１において右側）を通過し、下方へ移動する際には、誘導板１５５の手前側（図１１において左側）を通過する。 Thus, when the tip of the guide bar 131 moves upward, it passes the back side (right side in FIG. 11) of the guide plate 155, and when it moves downward, the front side of the guide plate 155. (Left side in FIG. 11).

そして、本変形例では、ガイド棒１３１を上方へ移動させる際、ガイド棒１３１の先端部が誘導板１５５により自動的に係止溝１１３，１１５側へ案内されることで、保持部材９３の位置決めが容易となる。
また、本変形例では、ガイド棒１３１を下方へ移動させる際、ガイド棒１３１の先端部が一旦、誘導板１５５に当接することで、クッションの役目を果し、急な下降を防止することができる。さらに、ガイド棒１３１を下方へ移動させる際、誘導板１５５の上片１５５ａにより各係止溝１１３，１１５への進入が防止され、ガイド棒１３１の先端部が各係止溝１１３，１１５へ進入することがなく、スムーズに下降させることができる。 In this modification, when the guide bar 131 is moved upward, the leading end portion of the guide bar 131 is automatically guided to the locking grooves 113 and 115 by the guide plate 155, thereby positioning the holding member 93. Becomes easy.
Further, in this modification, when the guide bar 131 is moved downward, the tip of the guide bar 131 once abuts against the guide plate 155, thereby serving as a cushion and preventing sudden lowering. it can. Further, when the guide bar 131 is moved downward, the upper piece 155a of the guide plate 155 prevents the entry into the locking grooves 113 and 115, and the tip of the guide bar 131 enters the locking grooves 113 and 115. It is possible to move down smoothly.

なお、本変形例では、右側の取付部１５３にのみ誘導部材１５１を設けたが、これに代えて、またはこれに加えて左側の取付部１５３にも誘導部材１５１を設けてもよい。
また、対角線上に誘導部材１５１を設けるようにしてもよい。つまり、下側の係止溝１１５，１１５に対しては右側の取付部１５３に誘導部材１５１が設けられ、上側の係止溝１１３，１１３に対しては左側の取付部１５３に誘導部材１５１を設けるようにしてもよく、その取付位置は適宜変更可能である。
さらに、誘導板１５５を付勢するバネ（１６５）の種類やその取付方法など、誘導板１５５の付勢の仕方は、適宜変更可能である。 In this modification, the guide member 151 is provided only on the right attachment portion 153, but the guide member 151 may be provided on the left attachment portion 153 instead of or in addition to this.
