Description

本発明は、ワークの搬送ラインの途中に設けられて、その搬送ラインの列数を集合減列あるいは振分増列させる搬送ラインの列数変更装置に係わり、特に、その集合減列もしくは振分増列させる際のワークの受け渡しが安定的に行え、かつ、ワークの渡り部に生じる隙間を可及的に縮小しつつ小型化が図れるようにした搬送ラインの列数変更装置に関する。   The present invention relates to an apparatus for changing the number of lines of a conveyance line provided in the middle of a conveyance line of a workpiece and for reducing the number of lines of the conveyance line to a set reduction or distribution, and in particular, to the set reduction or distribution thereof. The present invention relates to an apparatus for changing the number of lines in a conveying line that can stably deliver workpieces when increasing the number of rows and can reduce the size of a gap while reducing the gap generated in the workpiece transfer portion as much as possible.
ワークの搬送ラインの途中に設けられて、その搬送ラインの列数を2列から1列に減列集合させたり、あるいは1列から2列に増列振分させたりする搬送ラインの列数変更装置として、従来では図7の概略図に示すような揺動式のものが知られている。  Change the number of transfer lines that are provided in the middle of the work transfer line and that reduce the number of transfer lines from 2 to 1 or distribute the lines from 1 to 2 As a device, a swing type device as shown in the schematic diagram of FIG. 7 is conventionally known.
この揺動式の列数変更装置01は、2機のコンベア02a,02bを備えて2列の搬送ラインA,Bを有する複列搬送装置02と、1機のコンベア03aを備えて1列のみの搬送ラインCを有する単列搬送装置03との間に介設された接続切替用コンベア04でなり、当該接続切替用コンベア04は単列搬送装置03側の端部04aを揺動中心にして複列搬送装置02側の端部04bが当該複列搬送装置02の2列の搬送ラインA,Bの端部に交互に臨まされて揺動切替移動されるようになっている。   This swing type row number changing device 01 includes two conveyors 02a and 02b and two rows of conveying lines A and B, and one row of conveyors 03a and only one row. The connection switching conveyor 04 is interposed between the single-line transport device 03 having the transport line C, and the connection switching conveyor 04 has the end portion 04a on the single-row transport device 03 side as a swing center. The end portion 04b on the double-row transport device 02 side is alternately faced to the end portions of the two rows of transport lines A and B of the double-row transport device 02 and is swing-switching moved.
しかしながら、上記従来の列数変更装置01では、複列搬送装置02と単列搬送装置03との間に介在させた接続切替用コンベア04を揺動させて複列搬送装置02側の搬送ラインA,Bを選択的に切り替えるようにしているので、当該接続切替用コンベア04と複列搬送装置02のコンベア02a,02bまたは単列搬送装置03のコンベア03aとは、相互に斜めに接続されることになる。よって、その接続部のワークwの渡り部分に生じる隙間は必然的に左右が不均一になってしまうので、ワークwの受け渡しを安定させて確実に行わせるためには、接続角度を小さくして渡り部分の左右の隙間の差を小さくする必要があった。つまり、接続切替用コンベア04の全長を長くしてその揺動角度を小さくしなければならなかった。これ故、このような揺動式の列数変更装置01はその小型化を図るのが困難であった。   However, in the conventional row number changing device 01, the connection switching conveyor 04 interposed between the double-row transport device 02 and the single-row transport device 03 is swung to thereby carry the transfer line A on the double-row transport device 02 side. , B are selectively switched, so that the connection switching conveyor 04 and the conveyors 02a and 02b of the double-row transport device 02 or the conveyor 03a of the single-row transport device 03 are obliquely connected to each other. become. Therefore, the gap generated in the connecting part of the workpiece w of the connecting portion is inevitably non-uniform on the left and right. Therefore, in order to stably and reliably deliver the workpiece w, the connection angle must be reduced. It was necessary to reduce the difference between the gaps on the left and right of the crossing part. That is, it has been necessary to lengthen the overall length of the connection switching conveyor 04 and reduce its swing angle. Therefore, it has been difficult to reduce the size of such a swing type column number changing device 01.
また、ワークwはコンベア間の乗り移りに際し、その前後のコンベアでは搬送方向が異なっているので、当該ワークwの搬送姿勢に乱れが生じ易いという問題もあった。   Further, when the workpiece w is transferred between the conveyors, the conveyance directions of the conveyors before and after the conveyor are different, so that there is a problem that the conveyance posture of the workpiece w is easily disturbed.
この発明は、上記事情に鑑みてなされたものであり、その目的とするところは、ワークの渡り部分の左右の隙間を均一にすることができてワークの搬送姿勢を乱すことがなく、かつ装置の小型化が図れる搬送ラインの列数変更装置を提供することにある。   The present invention has been made in view of the above circumstances, and an object of the present invention is to be able to make the left and right gaps of the crossing part of the workpiece uniform so as not to disturb the conveying posture of the workpiece.

以下に、本発明に係る搬送ラインの列数変更装置の好適な一実施の形態例を、添附図面を参照して詳細に説明する。 図1〜図4は本発明に係る搬送ラインの列数変更装置を示すもので、図1はその側面図、図2はその平面図、図3は図1及び図2中に示すIII−III線部の矢視図、図4は同様に図1及び図2中に示すIV−IV線部の矢視図である。   A preferred embodiment of a transfer line column number changing apparatus according to the present invention will be described below in detail with reference to the accompanying drawings. 1 to 4 show an apparatus for changing the number of lines of a transport line according to the present invention, FIG. 1 is a side view thereof, FIG. 2 is a plan view thereof, and FIG. 3 is a III-III shown in FIGS. Similarly, FIG. 4 is an arrow view of the IV-IV line portion shown in FIGS. 1 and 2.
図示するように、この実施の形態では、搬送ラインの列数変更装置2は、ワークの搬送方向の上流側に配置された複列搬送装置4とその下流側に配置された単列搬送装置6との間に介設されて、上流側の複列搬送装置4から2列で送られてくるワークを受け取って、このワークを下流側の単列搬送装置6に1列に集合減列させて受け渡すようになっている。   As shown in the drawing, in this embodiment, the transfer line row number changing device 2 includes a double row transfer device 4 arranged on the upstream side in the workpiece transfer direction and a single row transfer device 6 arranged on the downstream side thereof. Is received between the upstream double-row transport device 4 and received in two rows, and the single-row transport device 6 on the downstream side collects the work in one row. It is supposed to be handed over.
複列搬送装置4はワークを搬送する平行な2つのベルトコンベア42a,42bを有しており、これら2つのベルトコンベア42a,42bによって形成される2列の搬送ラインA,Bは、略1列分の搬送ライン幅(つまり上記ベルトコンベア42a,42bのベルト幅寸法)以上の間隔を空けて相互に平行配置されている。   The double-row transport device 4 includes two parallel belt conveyors 42a and 42b for transporting workpieces, and the two rows of transport lines A and B formed by the two belt conveyors 42a and 42b are approximately one row. Are arranged in parallel with each other with an interval equal to or larger than the conveyance line width (that is, the belt width dimension of the belt conveyors 42a and 42b).
一方、単列搬送装置6は1つのベルトコンベア62のみを有しており、上記複列搬送装置4の下流端から所定長を隔てて、その搬送方向に沿って直列に配置されている。そして、この単列搬送装置6は、その単一のベルトコンベア62からなる搬送ラインCが複列搬送装置4の2列の搬送ラインA,Bに対して、その中央に位置されて搬送方向を同一にして直列に設けられている。   On the other hand, the single row conveyance device 6 has only one belt conveyor 62 and is arranged in series along the conveyance direction at a predetermined length from the downstream end of the double row conveyance device 4. The single-line transport device 6 is configured such that the transport line C composed of the single belt conveyor 62 is positioned in the center with respect to the two-line transport lines A and B of the double-row transport device 4. The same is provided in series.
そして、これら複列搬送装置4と単列搬送装置6との間に介設される列数変更装置2は、少なくとも搬送ラインA,Bの2列分の搬送幅を有している列数変更用コンベア22と、この列数変更用コンベア22をワークの搬送方向に対して直交させて平行に往復切替移動させる平行移動手段24とを備えている。この平行移動手段24は、列数変更用コンベア22をその往復平行移動ストロークの両端においては、その幅方向の一方側を上記複列搬送装置4の搬送ラインA,Bを形成するコンベア42a,42bのいずれか一方の延長線上に位置させるとともに、他方側を単列搬送装置6の搬送ラインCを形成するコンベア62の一端に臨ませるようになっている。つまり、往復平行移動される列数変更用コンベア22は、その搬送ラインA側に近接する幅方向一方側22aがコンベア42aの延長線上に位置されたときには、幅方向他方側22bが単列搬送装置のベルトコンベア62の一端に臨み、搬送ラインB側に近接する幅方向他方側22bがコンベア42aの延長線上に位置されたときには、幅方向一方側22aが単列搬送装置のベルトコンベア62の一端に臨むようになっている。   The row number changing device 2 interposed between the double row conveying device 4 and the single row conveying device 6 changes the number of rows having a conveying width corresponding to at least two rows of the conveying lines A and B. And a parallel moving means 24 for reciprocally switching the parallel number of the conveyor 22 for changing the number of rows perpendicularly to the conveying direction of the workpiece. The parallel moving means 24 is configured such that, at both ends of the reciprocating parallel movement stroke of the conveyor 22 for changing the number of rows, the conveyors 42a and 42b that form the conveying lines A and B of the double row conveying device 4 on one side in the width direction. Is positioned on one of the extension lines, and the other side faces one end of the conveyor 62 that forms the transport line C of the single-row transport device 6. In other words, the conveyor 22 for changing the number of rows that is reciprocally translated is such that when the one side 22a in the width direction close to the transport line A side is positioned on the extension line of the conveyor 42a, the other side 22b in the width direction is a single row transport device. When the other side 22b in the width direction facing the one end of the belt conveyor 62 is positioned on the extension line of the conveyor 42a, the one side 22a in the width direction becomes one end of the belt conveyor 62 of the single-row transport device. It comes to face.
そして、本図示例の実施の形態の列数変更装置2にあっては、さらに列数変更コンベア22と複列搬送装置4との間に、速度を増減速制御可能な間隔調整用コンベア26が付加されて設けられている。なお、当該間隔調整用コンベア26は、本実施の形態例に示すように、列数変更装置2を減列装置として機能させて、搬送ライン数を2つから1つに集合減列させる場合に設けられて望ましいものであるが、勿論省略することもできる。   In the row number changing device 2 according to the embodiment of the illustrated example, an interval adjusting conveyor 26 capable of increasing / decreasing the speed is further provided between the row number changing conveyor 22 and the double row conveying device 4. It is added and provided. In addition, as shown in the present embodiment, the interval adjusting conveyor 26 causes the column number changing device 2 to function as a column reducing device and reduces the number of conveying lines from two to one. Although it is desirable to be provided, it can of course be omitted.
先ず、この間隔調整用コンベア26(26a,26b)から説明すると、この間隔調整用コンベア26は全く同一の2機の単列ベルトコンベア(26a,26b)が一対に平行に配設されて構成されており、これら一対の各間隔調整用コンベア26a,26bは上流側に配置された複列搬送装置4の搬送ラインA,Bに沿って直列に一直線状に接続されている。従って、両間隔調整用コンベア26a,26bは複列搬送装置4と同様に、略1列分の搬送ライン幅(つまりベルトコンベアのベルト幅寸法)以上の間隔を空けて平行に配置されている。   First, the distance adjusting conveyor 26 (26a, 26b) will be described. The distance adjusting conveyor 26 is composed of two identical single row belt conveyors (26a, 26b) arranged in parallel. The pair of interval adjusting conveyors 26a and 26b are connected in series in a straight line along the transfer lines A and B of the double-row transfer device 4 arranged on the upstream side. Accordingly, both the interval adjusting conveyors 26a and 26b are arranged in parallel with an interval equal to or larger than the conveying line width of about one row (that is, the belt width dimension of the belt conveyor) in the same manner as the double row conveying device 4.
そして、各間隔調整用コンベア26の搬送始端には、ワークの受入を検知するワーク受入センサ82a,82bが設けられ、当該各ワーク受入センサ82a,82bから発せられる検知信号に応じて、制御手段8によって一対の各間隔調整用コンベア26a,26bの搬送速度がそれぞれ独立されて増減速制御されるようになっている。即ち、各間隔調整用コンベア26a,26bは、駆動ローラ262、テンションローラ264、従動ローラ266とに無端状の搬送ベルト268が巻回されてなるが、各間隔調整用コンベア26a,26bの駆動ローラ262に回転駆動力を伝達する電動モータ270の回転速度が、それぞれの間隔調整用コンベア26a,26bに投入されるワークの受入タイミングの相互関係に応じて、独立的に増減速制御されるようになっている。つまり、両間隔調整用コンベア26a,26b上から後述する列数変更用コンベア22上に移載されていくワークの間隔が所定範囲内に収まるように各間隔調整用コンベア26a,26bの速度が相互に独立して増減速制御されるようになっており、両間隔調整用コンベア26a,26bは通常では複列搬送装置4と単列搬送装置6とにおける搬送速度Vcよりも若干早く設定された標準速度V0で運転されるようになっている。なお、当該増減速制御の内容については後述する。   Then, workpiece receiving sensors 82a and 82b for detecting the acceptance of the workpiece are provided at the conveyance start end of each interval adjusting conveyor 26, and the control means 8 according to the detection signal generated from each workpiece receiving sensor 82a and 82b. Thus, the conveyance speeds of the pair of interval adjusting conveyors 26a and 26b are independently controlled to increase / decrease. In other words, each of the interval adjusting conveyors 26a and 26b is formed by winding an endless conveying belt 268 around a driving roller 262, a tension roller 264, and a driven roller 266, and the driving rollers of the interval adjusting conveyors 26a and 26b. The rotational speed of the electric motor 270 that transmits the rotational driving force to the H.262 is controlled to increase / decrease independently according to the mutual relationship of the receiving timings of the workpieces that are input to the interval adjusting conveyors 26a, 26b. It has become. In other words, the speeds of the interval adjusting conveyors 26a and 26b are mutually adjusted so that the interval between the workpieces transferred from the interval adjusting conveyors 26a and 26b to the later-described row number changing conveyor 22 is within a predetermined range. The two-interval adjusting conveyors 26a and 26b are normally set to be slightly faster than the conveying speed Vc in the double-row conveying device 4 and the single-row conveying device 6. The vehicle is operated at a speed V0. The details of the acceleration / deceleration control will be described later.
そして、列数変更用コンベア22は上述してあるように複列搬送装置4と単列搬送装置6との間に配設されるのであるが、本実施の形態では上記間隔調整用コンベア26a,26bが複列搬送装置4の下流端に直列接続されて設けられているので、当該間隔調整用コンベア26a,26bと単列搬送装置6との間に設けられている。この列数変更用コンベア22は、少なくとも2列分以上の搬送幅を有しており、少なくともその長手方向の一端は、その搬送ラインA側に近接する幅方向の一方側22aが複列搬送装置4の一方の搬送ラインAの端部に臨むか、あるいはその搬送ラインB側に近接する他方側22bが複列搬送装置4の他方の搬送ラインBの端部に臨むようになっている。また、長手方向の他端は、その幅方向の一方側22aあるいは他方側22bのいずれかが、単列搬送装置6の搬送ラインCを形成するコンベア62の一端に絶えず臨むようになっている。   The row number changing conveyor 22 is disposed between the double row conveying device 4 and the single row conveying device 6 as described above. In this embodiment, the interval adjusting conveyor 26a, Since 26 b is provided in series with the downstream end of the double-row transport device 4, it is provided between the interval adjusting conveyors 26 a and 26 b and the single-row transport device 6. The conveyor 22 for changing the number of rows has a conveyance width of at least two columns, and at least one end in the longitudinal direction thereof is a double-side conveyance device whose one side 22a in the width direction close to the conveyance line A side. 4, the other side 22 b close to the transport line B side faces the end of the other transport line B of the double-row transport device 4. In addition, the other end in the longitudinal direction is such that either one side 22a or the other side 22b in the width direction continuously faces one end of the conveyor 62 forming the transport line C of the single-row transport device 6.
ここで、本図示例では、列数変更用コンベア22はその環状の搬送ベルト222が幅方向に2本に分割形成されていて、一方側の搬送ベルト222aの搬送始端が複列搬送装置4及び間隔調整用コンベア26aの一方の搬送ラインAの終端に一致して臨まされているときに、他方側の搬送ベルト222bの搬送終端が単列搬送装置6の搬送ラインC、つまりベルトコンベア62の上流端に臨むようになっている。しかも、各搬送ベルト222a,222bの幅は間隔調整用コンベア26a,26b及び単列搬送装置6のベルトコンベア62のベルと幅とほぼ同一とされている。そして、これら2本の搬送ベルト222a,222bは同一回転軸上に設けられた駆動ローラ224、テンションローラ226、従動ローラ228とに巻回されて、単一の駆動モータ230によって回転駆動されるようになっていて、側面視では上記間隔調整用コンベア26と同一の構成になっている。   Here, in the illustrated example, the conveyor 22 for changing the number of rows has an annular conveying belt 222 divided into two in the width direction, and the conveying start end of the conveying belt 222a on one side is the double-row conveying device 4 and When facing the end of one transport line A of the interval adjusting conveyor 26a, the transport end of the transport belt 222b on the other side is the transport line C of the single-row transport device 6, that is, upstream of the belt conveyor 62. It comes to the end. Moreover, the widths of the conveyor belts 222a and 222b are substantially the same as the widths of the belts 62 of the interval adjusting conveyors 26a and 26b and the belt conveyor 62 of the single-row conveyor 6. These two conveyor belts 222 a and 222 b are wound around a drive roller 224, a tension roller 226, and a driven roller 228 provided on the same rotation shaft so as to be rotationally driven by a single drive motor 230. In the side view, the configuration is the same as that of the interval adjusting conveyor 26.
また、列数変更用コンベア22は平行移動手段24によって、その搬送方向と直行する方向に直線的に往復平行移動されるようになっている。即ち、列数変更用コンベア22は支持フレーム10上にリニアベアリング242を介して、その搬送方向と直行する方向に直線的に往復摺動移動自在に設けられていて、このは列数変更用コンベア22の機枠232から下方に延出されて一体的に設けられた駆動用バー244が搬送ラインA,Bと直交する方向に、駆動モータ246によって振られて往復移動されるようになっている。つまり、駆動用バー244の下端には縦方向に延びる係合溝248を有した係合部材250が一体的に取り付けられているとともに、駆動モータ246の出力軸端には回転円盤252に起立されて、上記係合溝248に摺動係合する偏芯されたクランクピン254が設けられていて、当該クランクピン254の偏芯回転運動が列数変更用コンベア22の往復平行移動に変換されて伝達されるようになっている。   In addition, the row number changing conveyor 22 is reciprocally translated linearly in a direction perpendicular to the conveying direction by the parallel moving means 24. That is, the row number changing conveyor 22 is provided on the support frame 10 via a linear bearing 242 so as to be linearly reciprocable in a direction perpendicular to the conveying direction. A driving bar 244 that extends downward from the machine casing 232 and is integrally provided is shaken by a driving motor 246 in a direction orthogonal to the transport lines A and B, and is reciprocated. . That is, an engaging member 250 having an engaging groove 248 extending in the vertical direction is integrally attached to the lower end of the driving bar 244, and the rotating disk 252 is raised at the output shaft end of the driving motor 246. An eccentric crank pin 254 that is slidably engaged with the engagement groove 248 is provided, and the eccentric rotational movement of the crank pin 254 is converted into the reciprocating parallel movement of the row number changing conveyor 22. It is to be transmitted.
また、上記各間隔調整用コンベア26a,26bの搬送始端にはワークの受入を検知するワーク受入センサ82(82a,82b)が設けられるとともに、その搬送終端にはワーク投入センサ84(84a,84b)が設けられ、さらに単列搬送装置6のコンベア62の搬送始端にもワーク受入センサ86が設けられている。そして、これらのセンサ82a,82b,84a,84b,86はマイクロコンピュータ等からなる制御手段8に接続され、当該制御手段8はこれらの各センサ82a,82b,84a,84b,86からの入力信号に応じて、一対の間隔調整用コンベア26a,26bの各駆動モータ270(270a,270b)と、列数変更用コンベア22を往復平行移動させる駆動モータ246との作動を制御するようになっている。即ち、ワーク受入センサ82a,82bからの信号に応じて制御手段8によって一対の各間隔調整用コンベア26a,26bの搬送速度をそれぞれ独立させて増減速制御するとともに、間隔調整用コンベア26a,26bから前記列数変更用コンベア22へのワークの投入を確認して、当該列数変更用コンベア22の往復平行移動動作を行わせるべく、各間隔調整用コンベア26a,26bの終端にワーク投入センサ84a,84bを設けて、このワーク投入センサ84a,84bが出力するワークの投入検知信号に応じて、前記制御手段8によって前記平行移動手段24の動作タイミングを制御するようになっている。なお、複列搬送装置4と単列搬送装置6とは同一の速度Vcで定速運転されるようになっている。   In addition, a workpiece receiving sensor 82 (82a, 82b) for detecting the acceptance of a workpiece is provided at the conveyance start of each of the interval adjusting conveyors 26a, 26b, and a workpiece input sensor 84 (84a, 84b) is provided at the conveyance termination. Furthermore, a workpiece receiving sensor 86 is also provided at the transfer start end of the conveyor 62 of the single-row transfer device 6. These sensors 82a, 82b, 84a, 84b, 86 are connected to a control means 8 comprising a microcomputer or the like, and the control means 8 receives input signals from these sensors 82a, 82b, 84a, 84b, 86. Accordingly, the operations of the drive motors 270 (270a, 270b) of the pair of interval adjusting conveyors 26a, 26b and the drive motor 246 that reciprocally translates the row number changing conveyor 22 are controlled. That is, according to the signals from the workpiece receiving sensors 82a and 82b, the control means 8 controls the speeds of the pair of interval adjusting conveyors 26a and 26b independently of each other, and the speed adjusting control is performed from the interval adjusting conveyors 26a and 26b. In order to confirm the input of the work to the row number changing conveyor 22 and to perform the reciprocating parallel movement operation of the row number changing conveyor 22, the work input sensor 84a, 84b is provided, and the control means 8 controls the operation timing of the parallel moving means 24 in accordance with the work input detection signals output from the work input sensors 84a and 84b. The double-row transport device 4 and the single-row transport device 6 are operated at a constant speed at the same speed Vc.
図5,図6は制御手段8によって行われる、一対の間隔調整用コンベア26a,26bと列数変更用コンベア22との作動制御内容を説明するフローチャートであり、図5は搬送ラインAから列数変更コンベヤ22にワークが投入供給されるときの制御内容を示し、図6は搬送ラインBから列数変更コンベヤ22にワークが投入供給されるときの制御内容を示しており、これらはほぼ同時に行われる。   5 and 6 are flowcharts for explaining the operation control contents of the pair of interval adjusting conveyors 26a and 26b and the row number changing conveyor 22 performed by the control means 8, and FIG. FIG. 6 shows the contents of control when workpieces are input / supplied to the change conveyor 22, and FIG. 6 shows the contents of control when workpieces are input / supplied from the transfer line B to the row change conveyor 22, which are performed almost simultaneously. Is called.
先ず、図5の搬送ラインA側からワークwが投入供給される場合の制御について説明する。図示するように、複列搬送装置2の搬送ラインA上を搬送されてくるワークwが、同じ搬送ラインA上に設けられている間隔調整用コンベア26aに投入されて載り移ったか否かをセンサ82aで検知し、載り移った場合には、当該搬送ラインA側の間隔調整用コンベア26aは基準速度Vのままに維持されてワークを搬送する(S10、S20)。   First, the control when the workpiece w is loaded and supplied from the transfer line A side in FIG. 5 will be described. As shown in the figure, a sensor is used to determine whether or not the workpiece w transported on the transport line A of the double-row transport device 2 has been put on and transferred to the interval adjusting conveyor 26a provided on the same transport line A. When detected by 82a and transferred, the interval adjusting conveyor 26a on the transfer line A side is maintained at the reference speed V and conveys the workpiece (S10, S20).
次に、列数変更用コンベア22が搬送ラインA側に位置されていて、その幅方向の一側22aの上流端が搬送ラインA側の間隔調整用コンベア26aの終端に臨んでいるか否かを判断する(S30)。ここで、この判断は、平行移動手段24の駆動モータ246の出力軸の回転角度をロータリーエンコーダ等のセンサー88で検知し、その出力信号を制御手段8に入力して判定することができる。あるいは、列数変更用コンベア22の幅方向への往復移動端にリミットスイッチ等を設けておき、その出力信号から判定することもできる。そして、当該判断がNoで、搬送ラインB側に位置されている場合には、列数変更用コンベア22を搬送ラインA側に移動させて良いか否かを判断し、当該判断がYesであれば、列数変更用コンベア22を搬送ラインA側に移動させて上記S30に戻る(S40、S50)。   Next, whether or not the row number changing conveyor 22 is positioned on the transport line A side, and whether or not the upstream end of one side 22a in the width direction faces the end of the interval adjusting conveyor 26a on the transport line A side is determined. Judgment is made (S30). Here, this determination can be made by detecting the rotation angle of the output shaft of the drive motor 246 of the parallel moving means 24 with a sensor 88 such as a rotary encoder and inputting the output signal to the control means 8. Alternatively, a limit switch or the like may be provided at the reciprocating end of the row number changing conveyor 22 in the width direction, and determination may be made from the output signal. If the determination is No and the vehicle is located on the transport line B side, it is determined whether the row number changing conveyor 22 can be moved to the transport line A side, and the determination is Yes. For example, the conveyor 22 for changing the number of rows is moved to the transport line A side, and the process returns to S30 (S40, S50).
ここで、当該列数変更用コンベア22の移動の可否の判断は、搬送ラインA側の間隔調整用コンベア26a上のワークwよりも先行して搬送されているワークwが搬送ラインB側の間隔調整用コンベア26b上に有るか否か、さらに、搬送ラインA側の間隔調整用コンベア26a上のワークwがその終端に達する以前に当該列数変更用コンベア22の移動を完了させ得るか否かで判定する。上記ワークwの有無は、上記搬送ラインA上に載り移ったワークよりも先行して検出されている搬送ラインB側の間隔調整用コンベア26b上のワークが列数変更用コンベア22に載り移っているか否かで判定し得る。また、上記移動完了の可否は、搬送ラインA側の間隔調整用コンベア26a上のワークwがその終端に到達するまでの時間と列数変更用コンベア22の移動完了に要する時間とをそれぞれ算出して比較することによって判定し得る。   Here, whether or not the row number changing conveyor 22 can be moved is determined by determining whether the work w being transported prior to the work w on the spacing adjusting conveyor 26a on the transport line A side is on the transport line B side. Whether or not it is on the adjustment conveyor 26b, and whether or not the movement of the row number changing conveyor 22 can be completed before the workpiece w on the interval adjustment conveyor 26a on the transport line A side reaches its end. Judge with. The presence / absence of the workpiece w is determined by the workpiece on the interval adjusting conveyor 26b on the conveyance line B side detected prior to the workpiece transferred on the conveyance line A being transferred to the row number changing conveyor 22. It can be determined by whether or not. In addition, whether or not the movement can be completed is calculated by calculating the time required for the work w on the conveyor 26a for adjusting the distance on the conveyance line A side to reach the terminal and the time required for completing the movement of the conveyor 22 for changing the number of columns. Can be determined by comparing them.
そして、S40での判断がNoの場合には、当該列数変更用コンベア22は移動させずに搬送ラインB側に位置させたままにし、搬送ラインA側の間隔調整用コンベア26a上を搬送されてくるワークwはそのまま落下排出させて(S60)、制御フローをリターンさせる。そして落下排出させたワークは下方に設けてある回収ボックスによって回収する。   If the determination in S40 is No, the row number changing conveyor 22 is not moved and is left on the conveying line B side, and is conveyed on the interval adjusting conveyor 26a on the conveying line A side. The incoming work w is dropped and discharged as it is (S60), and the control flow is returned. The dropped and discharged work is collected by a collection box provided below.
そして、上記S30での判断がYesであれば、ワークが列数変更用コンベア22に乗り移ったか否かをセンサ84aからの出力信号により検知してその載り移りのタイミングを判断し、これがYesになるまでループさせて待つ(S70)。そして、この判断がYesになって載り移りが確認されたならば、次に、列数変更用コンベア22を搬送ラインB側に平行移動させても良いか否かを判断する(S80)。ここで、当該S80での判断は、列数変更用コンベア22上をその幅方向の搬送ラインB側寄りの位置にて先行搬送されているワークが、単列搬送装置6のベルトコンベア62上に乗り移ったか否かで判定される。そして、列数変更用コンベア22を搬送ラインB側に向けて平行移動させた後(S90)、ワークが単列搬送装置6のベルトコンベア62上に乗り移ったか否かをセンサ86で検知して(S100)、その載り移りが確認できたならば制御フローをリターンさせる。   If the determination in S30 is Yes, whether or not the workpiece has been transferred to the row number changing conveyor 22 is detected from the output signal from the sensor 84a to determine the transfer timing, and this is Yes. (S70). If this determination is Yes and the transfer is confirmed, it is next determined whether or not the row number changing conveyor 22 may be moved in parallel to the transport line B side (S80). Here, the determination in S80 is that the work that has been transported in advance on the conveyor 22 for changing the number of rows at a position closer to the transport line B in the width direction is placed on the belt conveyor 62 of the single-row transport device 6. Judgment is made based on whether or not the vehicle has been transferred. After the number-of-rows changing conveyor 22 is translated toward the transfer line B (S90), the sensor 86 detects whether or not the workpiece has been transferred onto the belt conveyor 62 of the single-row transfer device 6 ( S100) If the transfer is confirmed, the control flow is returned.
次に、搬送ラインB側からワークが投入供給される場合の制御について説明する。図示するように、複列搬送装置2の搬送ラインA上を搬送されてくるワークwが、同じ搬送ラインA上に設けられている間隔調整用コンベア26aに投入されて載り移ったか否かをセンサ82aで検知し、載り移った場合には、タイマーを起動して時間計測を開始する(S110,S112)。爾後、複列搬送装置4の搬送ラインB上を搬送されてくるワークwが同じ搬送ラインB上にある間隔調整用コンベア26bに投入されて載り移ったか否かをセンサ82bで検知し、載り移りを検知した場合には、先行して搬送ラインA側から投入されたワークとの投入時間差Δtを算出する(S114,S116)。そして、搬送ラインB側の間隔調整用コンベア26bの増減制御値を上記Δtに応じて求める(S118)。 ここで、上記制御値は、投入時間差Δtに対応させた数値を予めマップ化させて記憶させておき、当該マップから読み出すようにすることができる。即ち、複列搬送装置4は原則として、その2つの搬送ラインAとBとによるワークwの搬送は、それぞれ同一の搬送速度Vc,搬送ピッチPcで行い、かつ搬送タイミングを相互に半ピッチずらすことを基本搬送パターンとし、このようなワークの投入タイミングであれば、間隔調整用コンベア26a,26bの運転速度の増減制御は行わずとも、列数変更用コンベア22を余裕をもって往復平行移動させながら、単列搬送装置6のコンベア62にワークwを集合減列させて載り移させていくことができる。しかし、複列搬送装置4の両搬送ラインA,B上を搬送されてくるワークwの搬送タイミングにズレが生じた場合には、列数変更用コンベア22の往復平行移動のタイミングと合わなくなり、ワークの受け渡しが上手くいかなくなってしまう。そこで、このような搬送タイミングのズレが生じた場合に、間隔調整用コンベア26a,26bの速度を増減調節することで、列数変更用コンベア22へのワークwの投入タイミングが受け渡し可能な範囲内に収まるように、搬送ラインA,B上のワークの相互間隔を所定値範囲内に維持して、列数変更用コンベア22の往復平行移動動作とこれへのワークの投入タイミングとを合わせる。   Next, control when a workpiece is input and supplied from the transfer line B side will be described. As shown in the figure, a sensor is used to determine whether or not the workpiece w transported on the transport line A of the double-row transport device 2 has been put on and transferred to the interval adjusting conveyor 26a provided on the same transport line A. If it is detected at 82a and has been transferred, the timer is activated to start time measurement (S110, S112). After that, the sensor 82b detects whether or not the workpiece w conveyed on the conveyance line B of the double-row conveyance device 4 has been loaded onto the interval adjusting conveyor 26b on the same conveyance line B and transferred. Is detected, a loading time difference Δt from the workpiece previously loaded from the transfer line A side is calculated (S114, S116). Then, an increase / decrease control value of the interval adjusting conveyor 26b on the transport line B side is obtained according to the above Δt (S118). Here, the control value can be stored by mapping a numerical value corresponding to the input time difference Δt in advance and reading it from the map. That is, in principle, the double-row transport device 4 transports the workpiece w along the two transport lines A and B at the same transport speed Vc and transport pitch Pc, and shifts the transport timing by a half pitch. Is the basic transfer pattern, and if it is such a workpiece input timing, while the increase / decrease control of the operation speed of the interval adjusting conveyors 26a, 26b is not performed, the row number changing conveyor 22 is reciprocally translated with a margin, The workpieces w can be transferred to the conveyor 62 of the single-row transport device 6 in a collective manner. However, when a deviation occurs in the conveyance timing of the workpiece w conveyed on both conveyance lines A and B of the double-row conveyance device 4, the timing of the reciprocating parallel movement of the conveyor 22 for changing the number of rows does not match. The work will not be delivered successfully. Therefore, when such a shift in the conveyance timing occurs, by adjusting the speed of the interval adjusting conveyors 26a and 26b to increase or decrease, the input timing of the workpiece w to the row number changing conveyor 22 is within a range that can be delivered. So that the distance between the workpieces on the transfer lines A and B is maintained within a predetermined value range, the reciprocating parallel movement operation of the conveyor 22 for changing the number of rows is matched with the workpiece loading timing.
つまり、上記基本パターンで搬送されている時の時間差Δt0を基準にして、計測算出された時間差Δtが小さければ、後続のワークを搬送している間隔調整用コンベア26bの速度を遅らせるか、あるいは先行するワークを搬送している間隔調整用コンベアの26aの速度を速くする。また、上記基準の時間差Δt0よりも計測算出した時間差Δtの方が大きければ、後続のワークを搬送している間隔調整用コンベア26bの速度を早くするか、あるいは先行するワークを搬送している間隔調整用コンベアの26aの速度を遅くする。本実施の形態では搬送ラインA側をメイン搬送ラインと見立てて定速で運転し、これに合わせて搬送ラインB側を速度調整するようにしている。   That is, if the measured time difference Δt is small with reference to the time difference Δt0 when transported in the basic pattern, the speed of the interval adjusting conveyor 26b transporting the subsequent workpiece is delayed or preceded. The speed of the interval adjusting conveyor 26a that is transporting the workpiece to be moved is increased. Further, if the measured time difference Δt is larger than the reference time difference Δt0, the speed of the interval adjusting conveyor 26b that conveys the subsequent workpiece is increased, or the interval that conveys the preceding workpiece. Reduce the speed of the adjusting conveyor 26a. In this embodiment, the transport line A side is regarded as the main transport line, and is operated at a constant speed, and the speed of the transport line B side is adjusted accordingly.
より詳しくは、制御手段8のデータテーブルに計測時間差Δtに対応する速度制御値をマッピングした制御用データマップが記憶されていて、制御手段8は計測時間差Δtに対応する制御値を読み取って間隔調整用コンベア26bの速度制御を行う。例えば、制御用データマップには、以下に示すような制御値データが格納されている。即ち、上記基準時間差Δt0に対する計測時間差Δtのズレに応じた速度補正係数が記憶されていて、計測時間差Δtが基準時間差Δt0に一致する近辺では、上記速度補正係数は1に設定され、実質的に速度制御は行われない。そして、補正当該ズレが正側に大きくなる程、補正係数は段階的に大きく設定されて増速制御される一方、負側に大きくなる程、補正係数は段階的に小さく設定されて減速制御される。即ち、具体的には、計測時間差Δtが0に近い時の補正係数は0.3とされ、速度は基準速度の30%に減速される。そしてこの速度は徐々に増速されていって、投入時までに70%までに回復させて列数変更用コンベア22への載り移り時の速度差を少なくする。一方、計測時間差Δtが基準時間差Δt0の2倍に近い時の補正係数は1.7とされ、速度は基準速度の170%に増速される。そしてこの速度は徐々に減速されていって、投入時までに130%までに抑えて、列数変更用コンベア22への載り移り時の速度差を少なくする。(S118,S120)。   More specifically, a control data map in which a speed control value corresponding to the measurement time difference Δt is mapped is stored in the data table of the control means 8, and the control means 8 reads the control value corresponding to the measurement time difference Δt to adjust the interval. The speed of the conveyor 26b is controlled. For example, control value data as shown below is stored in the control data map. That is, a speed correction coefficient corresponding to the deviation of the measurement time difference Δt with respect to the reference time difference Δt0 is stored, and in the vicinity where the measurement time difference Δt matches the reference time difference Δt0, the speed correction coefficient is set to 1, substantially. Speed control is not performed. The correction coefficient is set to be increased stepwise and the speed increase is controlled as the correction deviation becomes larger on the positive side, while the correction coefficient is set to be reduced stepwise and controlled to be reduced as the correction side is increased. The Specifically, the correction coefficient when the measurement time difference Δt is close to 0 is set to 0.3, and the speed is reduced to 30% of the reference speed. This speed is gradually increased, and is restored to 70% by the time of loading to reduce the speed difference when transferring to the conveyor 22 for changing the number of rows. On the other hand, when the measurement time difference Δt is close to twice the reference time difference Δt0, the correction coefficient is 1.7, and the speed is increased to 170% of the reference speed. This speed is gradually decelerated, and is reduced to 130% by the time of loading, thereby reducing the speed difference at the time of transfer to the row number changing conveyor 22. (S118, S120).
次に、列数変更用コンベア22が搬送ラインB側に位置されていて、その上流端が搬送ラインB側の間隔調整用コンベア26bの終端に臨んでいるか否かを判断する(S130)。そして、当該判断がNoで、搬送ラインA側に位置されている場合には、列数変更用コンベア22を搬送ラインB側に移動させて良いか否かを判断し、当該判断がYesであれば、列数変更用コンベア22を搬送ラインB側に移動させて(S140、S150)、S130に戻る。ここで、当該列数変更用コンベア22の移動の可否の判断は、前述した図5のフローチャートにおけるS40での判断と同様にして行われる。   Next, it is determined whether or not the row number changing conveyor 22 is positioned on the transport line B side and the upstream end thereof faces the end of the interval adjusting conveyor 26b on the transport line B side (S130). If the determination is No and the vehicle is positioned on the transport line A side, it is determined whether the row number changing conveyor 22 can be moved to the transport line B side, and the determination is Yes. For example, the conveyor 22 for changing the number of rows is moved to the transport line B side (S140, S150), and the process returns to S130. Here, the determination of whether or not the row number changing conveyor 22 can be moved is performed in the same manner as the determination in S40 in the flowchart of FIG. 5 described above.
そして、S140での判断がNoの場合には、当該列数変更用コンベア22は移動させずに搬送ラインA側に位置させたままにし、搬送ラインB側の間隔調整用コンベア26b上を搬送されてくるワークはそのまま落下排出させて(S160)、制御フローをリターンさせる。そして落下排出させたワークは下方に設けてある回収ボックスにて回収する。   If the determination in S140 is No, the row number changing conveyor 22 is not moved and is left on the conveying line A side, and is conveyed on the interval adjusting conveyor 26b on the conveying line B side. The incoming work is dropped and discharged as it is (S160), and the control flow is returned. The dropped and discharged workpiece is collected in a collection box provided below.
また、上記S130での判断がYesであれば、次には、ワークが列数変更用コンベア22に乗り移ったか否かをセンサ からの信号により検知して、その載り移りのタイミングを判断し、これがYesになるまでループさせて待つ(S170)。そして、この判断がYesになって載り移りが確認されたならば、次に上記間隔調整用コンベア26bの速度を基準速度Vに戻してから(S175)、列数変更用コンベア22を搬送ラインA側に平行移動させても良いか否かを判断する(S180)。ここで、当該S180での判断は、列数変更用コンベア22の搬送ラインA側上を先行して搬送されているワークが単列搬送装置6のベルトコンベア62上に乗り移ったか否かで判定される。そして、列数変更用コンベア22を搬送ラインA側に向けて平行移動させた後は、ワークが単列搬送装置6のコンベア62に乗り移ったか否かをセンサ で検知して判断し、その載り移りが確認できたならば制御フローはリターンする。   If the determination in S130 is Yes, then it is detected from the signal from the sensor whether the workpiece has been transferred to the row number changing conveyor 22, and the transfer timing is determined. It loops and waits until it becomes Yes (S170). If this determination is Yes and the transfer is confirmed, the speed of the interval adjusting conveyor 26b is then returned to the reference speed V (S175), and then the row number changing conveyor 22 is moved to the transport line A. It is then determined whether or not it is possible to translate it to the side (S180). Here, the determination at S <b> 180 is determined by whether or not the work that has been transported in advance on the transport line A side of the conveyor 22 for changing the number of rows has been transferred onto the belt conveyor 62 of the single-row transport device 6. The After the number-of-rows changing conveyor 22 is translated toward the transfer line A side, it is determined by detecting whether or not the workpiece has been transferred to the conveyor 62 of the single-row transfer device 6, and the transfer is performed. If it is confirmed, the control flow returns.
図7は上記制御内容にて作動制御される列数変更装置2の動作例を示した概略説明図である。なお、ここでは、複列搬送装置4における2列の搬送ラインA,B上をワークwがほぼ同じタイミングで並んで搬送されてきた場合で説明する。即ち、複列搬送装置4における2つの搬送ラインA,Bのコンベア22a,22b上から、これらに直列に設けられている一対の間隔調整用コンベア26a,26b上にワークWがそれぞれ載り移ると、各間隔調整用コンベア26a,26bの搬送始端に設けられているセンサー82a,82bがそれを検知してワークの受入信号をそれぞれ発信する。制御手段8はその信号を受けるとそれら一対の間隔調整用コンベア26a,26bの運転速度を個別に独立させて制御し、搬送ラインA側の間隔調整用コンベア26aは基準速度Vのままに維持して作動させる一方、搬送ラインB側の間隔調整用コンベア26bは基準速度Vの30%程度まで減速させてから70%程度まで徐々に増速して作動させる。このため、搬送ラインA側のワークwが先行して搬送されていくことになる(図7(1),(2)参照)。そして、列数変更用コンベア22が搬送ラインA側に位置しているか否かが判断され、搬送ラインB側に位置されている場合には、当該列数変更用コンベア22を搬送ラインA側に移動することの可否が判定されて、搬送ラインB側に先行して搬送されているワークが有る場合と、当該列数変更用コンベア22の搬送ラインA側への移動が間に合わない場合とを除いて、原則的に列数変更用コンベア22は搬送ラインA側に平行移動される。   FIG. 7 is a schematic explanatory view showing an example of the operation of the column number changing device 2 which is controlled to operate according to the above control contents. Here, a case will be described in which the workpieces w are transported side by side at substantially the same timing on the two rows of transport lines A and B in the double-row transport device 4. That is, when the workpieces W are transferred from the conveyors 22a and 22b of the two conveying lines A and B in the double-row conveying device 4 onto the pair of interval adjusting conveyors 26a and 26b provided in series with each other, Sensors 82a and 82b provided at the conveyance start ends of the respective interval adjusting conveyors 26a and 26b detect it and send workpiece acceptance signals. Upon receipt of the signal, the control means 8 controls the operation speeds of the pair of interval adjusting conveyors 26a and 26b independently of each other, and the interval adjusting conveyor 26a on the transport line A side is maintained at the reference speed V. On the other hand, the interval adjusting conveyor 26b on the transport line B side is decelerated to about 30% of the reference speed V and then gradually increased to about 70%. For this reason, the workpiece w on the transfer line A side is transferred in advance (see FIGS. 7A and 7B). Then, it is determined whether or not the row number changing conveyor 22 is located on the transfer line A side. When the row number changing conveyor 22 is located on the transfer line B side, the row number changing conveyor 22 is moved to the transfer line A side. Except for the case where it is determined whether or not it is possible to move and there is a work that has been transported ahead on the transport line B side, and when the movement of the row number changing conveyor 22 to the transport line A side is not in time. Thus, in principle, the conveyor 22 for changing the number of rows is moved in parallel to the transport line A side.
そして、搬送ラインA側にて先行するワークwが列数変更用コンベア22に投入されて載り移り、これをセンサー84aが検出して当該載り移りが確認されると列数変更用コンベア22は搬送ラインB側へと平行移動される。これにより、列数変更用コンベア22の搬送ラインA側に近接した幅方向の一方側22aはその搬送方向終端部が単列搬送装置6のベルトコンベア62の始端に臨まされるとともに、搬送ラインB側に近接した幅方向の他方側22bはその搬送始端が搬送ラインB側の間隔調整用コンベア26bの終端に臨まされる(図7(3),(4)参照)。   Then, the preceding work w on the transfer line A side is loaded and transferred to the row number changing conveyor 22, and when the transfer is confirmed by the sensor 84a, the row number changing conveyor 22 is transferred. Translated to the line B side. As a result, one end 22a in the width direction adjacent to the conveying line A side of the conveyor 22 for changing the number of rows faces the starting end of the belt conveyor 62 of the single-row conveying device 6 and the conveying line B The conveyance start end of the other side 22b in the width direction adjacent to the side faces the end of the interval adjusting conveyor 26b on the conveyance line B side (see FIGS. 7 (3) and (4)).
次に、搬送ラインB側の間隔調整用コンベア26b上を減速されて搬送されてきたワークwが列数変更用コンベア22の幅方向の他方側22bの搬送ラインB側寄りの部分に投入されて、その載り移りがセンサー84bで検知されると、間隔調整用コンベア26は基準速度Vaに戻される。そして、幅方向の一方側22aの搬送ラインA側寄りの部分を単列搬送装置6のコンベア62の始端に向けて先行して搬送されているワークwが、当該単列搬送装置6のコンベア62に載り移ったことをセンサ86で検知して確認すると、列数変更コンベア22を搬送ラインA側に向けて平行移動させ、列数変更用コンベア22の幅方向他方側22bの終端を単列搬送装置6のコンベア62の始端に臨ませるとともに、幅方向一方側22aの始端を搬送ラインA側の間隔調整用コンベア26aの終端に臨ませる。これにより、列数変更用コンベア22の幅方向の他方側22b上を搬送されていくワークwは、単列搬送装置6のコンベア62に乗り移っていき、一方側22aの始端には新たに間隔調整用コンベア26aからワークが乗り移ってくることになる(図7(5),(6),(7)参照)。   Next, the work w that has been decelerated and conveyed on the interval adjusting conveyor 26b on the conveyance line B side is thrown into a portion near the conveyance line B side on the other side 22b in the width direction of the conveyor 22 for changing the number of rows. When the transfer is detected by the sensor 84b, the interval adjusting conveyor 26 is returned to the reference speed Va. And the workpiece | work w conveyed ahead toward the conveyance line A side part of the one side 22a of the width direction toward the start end of the conveyor 62 of the single row conveying apparatus 6 is the conveyor 62 of the said single row conveying apparatus 6. When the sensor 86 detects and confirms that the transfer has been made, the column number changing conveyor 22 is translated toward the transfer line A side, and the end of the width direction other side 22b of the column number changing conveyor 22 is transferred in a single row. The starting end of the conveyor 62 of the apparatus 6 is made to face, and the starting end of the one side 22a in the width direction is made to face the end of the interval adjusting conveyor 26a on the transport line A side. As a result, the work w being conveyed on the other side 22b in the width direction of the conveyor 22 for changing the number of rows is transferred to the conveyor 62 of the single row conveying device 6, and a new interval adjustment is made at the starting end of the one side 22a. The workpiece is transferred from the conveyor 26a (see FIGS. 7 (5), (6), (7)).
従って、以上のようにしてなる本実施の形態の搬送ラインの列数変更装置2では、複列搬送装置4の2列の搬送ラインA,B上をワークwがほぼ同じタイミングで搬送されてきても、搬送ラインA側の間隔調整用コンベア26aは基準速度のままで運転する一方、搬送ラインB側の間隔調整用コンベア26Bは減速運転することで、両間隔調整用コンベア26a,26b上を搬送されてくるワークwの相互間隔を調整し得る。よって、複列搬送装置の2列の搬送ラインA,Bの上を搬送されてくるワークwの相互間隔に乱れが生じていても、列数変更用コンベア22の往復平行移動タイミングとワークの投入タイミングとを合わせることができ、複列搬送装置の2列の搬送ラインA,Bから送られてくるワークを確実に列数変更用コンベア22に乗り移らせることができるようになる。また、上流側の複列搬送装置4の2列の搬送ラインA,B上を送られてくるワークwを、往復平行移動される列数変更コンベア22によって集合させて下流側の単列搬送装置6の1列の搬送ラインCに移載するので、ワークが受け渡されるコンベア間の搬送方向が直線状となり、もってワークwの受け渡し時の渡り部分に生じる隙間を均一かつ極小となし得、当該ワークwの乗り移りを円滑に行わせることができ、搬送姿勢に乱れを生じさせることがない。また、従来の揺動切替式の列数変更装置に比して、列数変更用コンベア22の搬送路長を格段に短くすることができ、もって装置の可及的な小型化が図れるようになる。   Therefore, in the transfer line column number changing device 2 of the present embodiment configured as described above, the workpieces w are transferred on the two transfer lines A and B of the double-row transfer device 4 at substantially the same timing. On the other hand, the interval adjusting conveyor 26a on the transfer line A side operates at the reference speed, while the interval adjusting conveyor 26B on the transfer line B side is decelerated, so that it is conveyed on both the interval adjusting conveyors 26a and 26b. The mutual space | interval of the workpiece | work w to be performed can be adjusted. Therefore, even if there is a disturbance in the mutual interval of the workpieces w conveyed on the two rows of the conveyance lines A and B of the double row conveyance device, the reciprocating parallel movement timing of the row number changing conveyor 22 and the loading of the workpieces The timing can be matched, and the workpieces sent from the two rows of the transfer lines A and B of the double row transfer device can be reliably transferred to the row number changing conveyor 22. In addition, the downstream single-line transport device is configured by collecting the workpieces w sent on the two-line transport lines A and B of the upstream double-row transport device 4 by the row number changing conveyor 22 that is reciprocally translated. 6, the transfer direction between the conveyors to which the workpieces are transferred is linear, and the gap generated in the transfer portion when transferring the workpieces w can be made uniform and minimal. The transfer of the workpiece w can be performed smoothly, and the conveyance posture is not disturbed. Also, the length of the conveying path of the conveyor 22 for changing the number of rows can be significantly shortened as compared with the conventional switching device for changing the number of rows, so that the apparatus can be miniaturized as much as possible. Become.
また、以上に説明した実施の形態では、ワークの搬送方向上流側に配置した複列搬送装置と下流側に配置した単列搬送装置との間に列数変更装置を設けて、搬送ライン数を集合減列させる場合を例示したが、本発明はこれに限られることはなく、搬送方向の上流側に配置した単列搬送装置と下流側に配置した複列搬送装置との間に列数変更装置を設けて、搬送ライン数を1つから2つに振り分け増列させる場合にも適用できる。この場合、間隔調整用コンベアは特に設ける必要はない。   In the embodiment described above, a column number changing device is provided between the double row conveyance device arranged upstream in the workpiece conveyance direction and the single row conveyance device arranged downstream, and the number of conveyance lines is set. The case of collective column reduction is illustrated, but the present invention is not limited to this, and the number of columns is changed between a single-row conveyance device arranged upstream in the conveyance direction and a double-row conveyance device arranged downstream. The present invention can also be applied to a case where an apparatus is provided and the number of transfer lines is increased from one to two. In this case, it is not necessary to provide a gap adjusting conveyor.
そして、このような振り分け増列装置として、列数変更装置を機能させる場合にあっても、上流側の単列搬送装置の1列の搬送ライン上を送られてくるワークを、往復平行移動される列数変更コンベアによって振り分けて下流側の2複列搬送装置の2列の搬送ラインに移載するので、ワークが受け渡されるコンベア間の搬送方向は直線状となり、ワークの渡り部分に生じる隙間を均一かつ極小となし得、当該ワークを円滑に乗り移りさせることができ、搬送姿勢に乱れを生じさせることがない。また、従来の揺動切替式の列数変更装置に比して、列数変更用コンベアの搬送長を格段に短くすることができ、装置の可及的な小型化が図れるようになる。   Even when the column number changing device is functioning as such a sorting and increasing device, the workpieces sent on the transport line of one row of the upstream single-row transport device are reciprocally translated. The transfer direction between the conveyors to which the workpieces are transferred becomes a straight line, and the gap generated in the crossing portion of the workpieces. Can be made uniform and minimal, the workpiece can be transferred smoothly, and the conveyance posture is not disturbed. Further, compared with a conventional swing switching type column number changing device, the conveying length of the row number changing conveyor can be remarkably shortened, and the device can be miniaturized as much as possible.
