[Detection means 20]
The detection means 20 is an article passage detection means that is disposed at a predetermined position on the conveyance path of the conveyance means 10 and detects passage of the article W. As the detection means 20, a reflective or transmissive optical sensor, a laser detector, an image sensor, a line camera capable of acquiring images of a plurality of line pixels, or the like can be used. Further, the detection means 20 may have a light emitting section and a light receiving section arranged above and below with the conveyance path interposed therebetween.

検知手段20は、搬送手段10の搬送方向に沿って複数個所に配されている構成を採る。本実施の形態では、検知手段21がコンベア11(1)の直前に配され、別の検知手段22がコンベア11(5)とコンベア16との間の配された構成を採る(検知手段21、22はまとめて「検知手段20」と記す場合がある)。 The detection means 20 is arranged at a plurality of locations along the conveyance direction of the conveyance means 10. In this embodiment, the detection means 21 is arranged immediately before the conveyor 11(1), and another detection means 22 is arranged between the conveyor 11(5) and the conveyor 16 (detection means 21, 22 may be collectively referred to as "detection means 20").

検知手段20は、コンベア11における左右のコンベアL、Rを搬送される一対の物品Wそれぞれについて、当該物品Wが検知手段20を通過する時刻を検出することができる。これにより、コンベアL、Rを搬送される一対の物品Wの通過時刻の差(物品搬送周期の位相差)や、左右何れかの物品Wの欠品を検出して制御部80に検出結果を出力することができる。 The detection means 20 can detect, for each of the pair of articles W conveyed on the left and right conveyors L and R of the conveyor 11, the time at which the article W passes through the detection means 20. As a result, the difference in passing times of the pair of articles W conveyed on the conveyors L and R (phase difference in article conveyance cycle) and the shortage of either the right or left article W are detected and the detection results are sent to the control unit 80. It can be output.

具体的には、検知手段21において、コンベアL、Rによって搬送される物品の何れかに物品に所定時間以上の遅れが検出された場合には、制御部80の指示に基づき、後段のコンベア11(1)~(5)の何れか又は全部について、コンベアL、Rを異なる速度で駆動することにより、遅れを補正することができる。このとき、コンベア11(1)~(5)における各コンベアL、Rの速度又は速度差が、コンベア11(1)~(5)ごとに異なるように設定される構成としてもよい。 Specifically, when the detection means 21 detects a delay of more than a predetermined time in either of the articles conveyed by the conveyors L and R, the subsequent conveyor 11 Regarding any or all of (1) to (5), the delay can be corrected by driving the conveyors L and R at different speeds. At this time, the speeds or speed differences of the conveyors L and R in the conveyors 11(1) to (5) may be set to be different for each of the conveyors 11(1) to (5).

また、検知手段22において、コンベアL、Rによって搬送される物品の何れかに所定時間以上の遅れが検出された場合には、制御部80の指示に基づき、後段の移載手段30により、当該一対の物品は搬送手段40に移載することなく、排出路50にそのまま通過させて排出する処理が行われる。検知手段21において、左右何れかの物品Wの欠品が検出された場合にも同様の処理が行われる。 Further, when the detection means 22 detects a delay of more than a predetermined time in either of the articles conveyed by the conveyors L, R, the subsequent transfer means 30, based on instructions from the control section 80, The pair of articles is not transferred to the conveyance means 40, but is allowed to pass through the discharge path 50 as is, and is discharged. Similar processing is performed when the detecting means 21 detects that either the right or left article W is out of stock.

[移載手段30]
移載手段30は、物品Wを搬送手段10から搬送手段40に移載可能な機構ユニットである。
[Transfer means 30]
The transfer means 30 is a mechanical unit that can transfer the article W from the conveyance means 10 to the conveyance means 40.

図1~4に示すように、主な要素として、フレーム31と、固定軸32と、上部回転板33と、吸着ユニット34(1)~(6)と、接続チューブ35(1)~(6)と、吸着ヘッド36(1)~(6)と、主ロータ37と、ステータ38と、モータ39とを備える。 As shown in FIGS. 1 to 4, the main elements are a frame 31, a fixed shaft 32, an upper rotating plate 33, suction units 34(1) to (6), and connecting tubes 35(1) to (6). ), suction heads 36 (1) to (6), a main rotor 37, a stator 38, and a motor 39.

以下、移載手段30における、各部の構成について、説明する。 The configuration of each part in the transfer means 30 will be explained below.

フレーム31は、基盤31aから立設され、移載手段30の主軸30Axを軸支するための逆L字形状をした構造部材である。 The frame 31 is an inverted L-shaped structural member that stands upright from the base 31a and supports the main shaft 30Ax of the transfer means 30.

固定軸32は、フレーム31によって主軸30Axに沿って軸支される鉛直方向に延伸する固定軸である。 The fixed shaft 32 is a fixed shaft that is supported along the main axis 30Ax by the frame 31 and extends in the vertical direction.

上部回転板33は、軸受け33aを介して固定軸32に軸支されており、主軸30Axの回りを半時計方向(図1、図2、におけるR1)に回転する円盤状の部材である。上部回転板33は、後述する主ロータ37の回転に伴って主軸30Axの回りを回転する。 The upper rotating plate 33 is a disk-shaped member that is pivotally supported by the fixed shaft 32 via a bearing 33a and rotates counterclockwise (R1 in FIGS. 1 and 2) around the main shaft 30Ax. The upper rotary plate 33 rotates around a main shaft 30Ax in accordance with the rotation of a main rotor 37, which will be described later.

上部回転板33には、周縁部付近に複数の吸着ユニット34(1)~(6)が、それぞれの中心軸34Axの回りを自転(図1、図2、におけるR2)可能な状態で周方向に等間隔に懸架されており、吸着ユニット34(1)~(6)には、物品Wを吸着保持するための吸着ヘッド36(1)~(6)が最下部に接続されている。 The upper rotary plate 33 has a plurality of suction units 34 (1) to (6) near its periphery in a circumferential direction in a state where they can rotate around their respective central axes 34Ax (R2 in FIGS. 1 and 2). The suction units 34(1) to (6) have suction heads 36(1) to (6) for suctioning and holding the article W connected at the bottom thereof.

上部回転板33の回転に伴って吸着ユニット34(1)~(6)も主軸30Axの回りを回転(図1、図2、におけるR1)する際に、各吸着ユニット34は、主軸30Axの回りの回転に伴って、それぞれが中心軸34Axの回りを半時計方向に自転して(図1、図2、におけるR2)、結果として、中心軸34Ax回りの角度は変化しないように構成されている。そのため、吸着ユニット34(1)~(6)に保持された吸着ヘッド36(1)~(6)は、主軸30Axの回りの回転に伴って中心軸34Ax回りの角度が変化することなく、吸着ヘッド36に吸着保持された物品WのX-X平面方向の向きも変化しない。 When the suction units 34 (1) to (6) also rotate around the main shaft 30Ax (R1 in FIGS. 1 and 2) with the rotation of the upper rotary plate 33, each suction unit 34 rotates around the main shaft 30Ax. With the rotation of , each rotates counterclockwise around the central axis 34Ax (R2 in FIGS. 1 and 2), and as a result, the angle around the central axis 34Ax does not change. . Therefore, the suction heads 36 (1) to (6) held by the suction units 34 (1) to (6) do not change their angles around the central axis 34Ax as they rotate around the main axis 30Ax. The orientation of the article W held by the head 36 in the XX plane direction also does not change.

これより、移載手段30によれば、物品Wの平面方向の向きを変えることなく、搬送手段10から物品Wを搬送手段40に移載することができる。 Therefore, according to the transfer means 30, the article W can be transferred from the conveyance means 10 to the conveyance means 40 without changing the plane direction of the article W.

主ロータ37は、上部回転板33と一体となって、主軸30Axの回りを半時計方向(図1、図2、におけるR1)に回転する円盤状の部材である。 The main rotor 37 is a disk-shaped member that rotates in a counterclockwise direction (R1 in FIGS. 1 and 2) around the main shaft 30Ax, integrally with the upper rotating plate 33.

ステータ38は、主ロータ37の下方に位置し回転のベースとなる部材であり、主軸30Axを駆動軸391とし主ロータ37を回転駆動するモータ39を内装する。 The stator 38 is a member located below the main rotor 37 and serves as a rotational base, and includes a motor 39 that rotationally drives the main rotor 37 with the main shaft 30Ax as a drive shaft 391.

また、主ロータ37、ステータ38は、吸着ヘッド36(1)~(6)への配管経路における回転バルブ機構として機能する。 Further, the main rotor 37 and stator 38 function as a rotary valve mechanism in the piping route to the suction heads 36(1) to (6).

以下、物品移載装置1における、各部の構成の詳細について、説明する。
[Detailed configuration of transfer means 30]
The details of the configuration of each part in the article transfer device 1 will be described below.

図6(a)は、吸着ユニット34、接続チューブ35、吸着ヘッド36の構成を示す正面図、(b)は、右側面図である。 FIG. 6(a) is a front view showing the configuration of the suction unit 34, the connection tube 35, and the suction head 36, and FIG. 6(b) is a right side view.

図6(a)、図6(b)に示すように、吸着ユニット34は、シャフト345にプーリー342が係合されており、軸方向に中心軸34Axを挟んで配される一対の軸受け341に回転自在に軸支され、軸受け341を介して上部回転板33と主ロータ37に取り付けられている。 As shown in FIGS. 6(a) and 6(b), in the suction unit 34, a pulley 342 is engaged with a shaft 345, and a pair of bearings 341 are disposed on both sides of the central axis 34Ax in the axial direction. It is rotatably supported and attached to the upper rotating plate 33 and the main rotor 37 via a bearing 341.

図7(a)は、図3におけるB-B断面図である。同図に示すように、主ロータ37の上面には、固定軸32の回りに固定プーリー346が、周縁付近に周方向に等間隔にプーリー342(1)~(6)が、周方向におけるプーリー342(1)~(5)、(6)~(1)の間に5個の従動プーリー344が配されている。さらに、周方向におけるプーリー342(5)と(6)の間には、プーリー342(5)と(6)に対し固定プーリー348よりも離れた位置に、固定プーリー348を上下に挟むように一対の従動プーリー349が配されている。 FIG. 7(a) is a sectional view taken along line BB in FIG. As shown in the figure, on the upper surface of the main rotor 37, a fixed pulley 346 is arranged around the fixed shaft 32, and pulleys 342 (1) to 342 (6) are arranged at equal intervals in the circumferential direction near the periphery. Five driven pulleys 344 are arranged between 342(1)-(5) and (6)-(1). Further, between the pulleys 342 (5) and (6) in the circumferential direction, a pair of fixed pulleys 348 is placed between the fixed pulleys 348 above and below at a position farther from the pulleys 342 (5) and (6) than the fixed pulley 348. A driven pulley 349 is arranged.

そして、エンドレスベルト343が、図7(a)に示される経路、すなわち、プーリー342(1)~(5)の間では、プーリー342(1)~(5)と従動プーリー344とに交互に懸架され、プーリー342(5)~(6)の間では、一対の従動プーリー349を経由して固定プーリー348に懸架される経路で引き回される構成を採る。 The endless belt 343 is alternately suspended between the pulleys 342(1) to 342(5) and the driven pulley 344 along the path shown in FIG. Between the pulleys 342(5) and 342(6), a configuration is adopted in which the pulley is routed via a pair of driven pulleys 349 and suspended from a fixed pulley 348.

係る構成により、主ロータ37の回転に伴って吸着ヘッド36(1)~(6)に接続されるシャフト345と同心に接続されたプーリー342(1)~(6)が、主軸30Axの回りを回転したときに、プーリー342(1)~(6)はエンドレスベルト343によってそれぞれの中心軸34Ax回りの角度を一定に保ち、吸着ヘッド36(1)~(6)の中心軸34Ax回りの角度を一定に保つことができる。 With this configuration, as the main rotor 37 rotates, the pulleys 342 (1) to (6), which are connected concentrically to the shaft 345 connected to the suction heads 36 (1) to (6), rotate around the main shaft 30Ax. When rotated, the pulleys 342 (1) to (6) maintain a constant angle around their respective central axes 34Ax by the endless belt 343, and the angles around the central axes 34Ax of the suction heads 36 (1) to (6) are kept constant by the endless belt 343. can be kept constant.

シャフト345の下端は上方からシリンダ346に挿抜自在に挿入されており、シリンダ346の下方には、気室347と吸着ヘッド36が、軸方向に当該順に接続されている。 The lower end of the shaft 345 is inserted into and removed from the cylinder 346 from above, and an air chamber 347 and a suction head 36 are connected in this order in the axial direction below the cylinder 346.

シリンダ346の外周面にはカムフォロア346aが突出しており、カムフォロア346aがステータ38の外周面に設けられたカム溝38aに沿って上下に動くことにより、シリンダ346は軸方向に往復移動して、吸着ヘッド36を上下に移動させることができる。 A cam follower 346a protrudes from the outer peripheral surface of the cylinder 346, and as the cam follower 346a moves up and down along a cam groove 38a provided on the outer peripheral surface of the stator 38, the cylinder 346 reciprocates in the axial direction and attracts The head 36 can be moved up and down.

図8(a)は、図3におけるD-D断面図である。同図に示すように、吸着ヘッド36(1)~(6)に接続されたシリンダ346(1)~(6)に配されたカムフォロア346aが、ステータ38の周面のカム溝38aに係合して動作する。 FIG. 8(a) is a sectional view taken along line DD in FIG. As shown in the figure, cam followers 346a arranged in cylinders 346(1) to (6) connected to suction heads 36(1) to (6) engage with cam grooves 38a on the circumferential surface of the stator 38. and it works.

図9(a)は、物品移載装置1における、吸着ヘッド36の回転角度θと吸着ヘッド36との高さとの関係を示す図である。主ロータ37の円周と搬送手段10とが平行になるときの回転角度θ(図8(a)における6時方向)を0度、主ロータ37の円周と搬送手段40とが平行になるときの回転角度θ(図8(a)における3時方向)を+90度としたとき、カム溝38aは、図9(a)に示すように、回転角度θが0度と90度付近において高さLまで吸着ヘッド36が下降し、その前後では吸着ヘッド36は高さHまで緩やかに上昇して高さHを維持するように構成されている。ここで、高さLとは吸着ヘッド36の吸着孔361が物品Wを吸引可能な高さをさし、高さHとは物品Wの移載に必要な高さをさす。 FIG. 9A is a diagram showing the relationship between the rotation angle θ of the suction head 36 and the height of the suction head 36 in the article transfer device 1. The rotation angle θ (6 o'clock direction in FIG. 8(a)) when the circumference of the main rotor 37 and the conveyance means 10 become parallel is 0 degrees, and the circumference of the main rotor 37 and the conveyance means 40 become parallel. When the rotation angle θ (3 o'clock direction in FIG. 8(a)) is +90 degrees, the cam groove 38a has a high height when the rotation angle θ is around 0 degrees and 90 degrees, as shown in FIG. 9(a). The suction head 36 descends to a height L, and before and after that, the suction head 36 gradually rises to a height H and maintains the height H. Here, the height L refers to the height at which the suction hole 361 of the suction head 36 can suck the article W, and the height H refers to the height necessary for transferring the article W.

吸着ヘッド36には、下面に複数の吸着孔361が設けられている。複数の吸着孔361は吸着ヘッド36の内に配設された管路36aと気室347内の管路347a、347bとを経由して、気室347の外周面から延出される接続チューブ35に接続される。 The suction head 36 is provided with a plurality of suction holes 361 on the lower surface. The plurality of suction holes 361 are connected to the connecting tube 35 extending from the outer peripheral surface of the air chamber 347 via a conduit 36a disposed in the suction head 36 and conduits 347a and 347b in the air chamber 347. Connected.

図7(b)は、図3におけるC-C断面図である。同図に示すように、平面視において、吸着ヘッド36(1)~(6)に接続された気室347(1)~(6)内の管路347bから延出される接続チューブ35(1)~(6)は主ロータ37の外周面において、主ロータ37内に設けられた管路37bに接続され、主ロータ37(1)~(6)の下面の回転出口孔37a(1)~(6)に挿通されている。本実施の形態では、回転出口孔37a(1)~(6)は、孔中心の主軸30Axの円周方向における角度(例えば、図8(a)に示す6時方向(0°)に対する偏角)が、対応する吸着ユニット34(1)~(6)の中心軸34Axの主軸30Axの円周方向における角度と一致するように構成されている。そのため、回転出口孔37a(1)~(6)と吸着ヘッド36(1)~(6)との主軸30Axの周りを回転角度は一致する構成としている。しかしながら、回転出口孔37aが開設される主軸30Axの円周方向における角度は上記した例に限定されないことは言うもでもない。 FIG. 7(b) is a sectional view taken along line CC in FIG. As shown in the figure, in plan view, a connecting tube 35(1) extends from a conduit 347b in the air chambers 347(1) to (6) connected to the suction heads 36(1) to (6). ~(6) are connected to the conduit 37b provided in the main rotor 37 on the outer circumferential surface of the main rotor 37, and rotation outlet holes 37a(1)~( 6). In the present embodiment, the rotation outlet holes 37a(1) to (6) are formed at an angle in the circumferential direction of the main axis 30Ax at the center of the hole (for example, an angle of deviation with respect to the 6 o'clock direction (0°) shown in FIG. 8(a)). ) is configured to coincide with the angle of the main axis 30Ax of the central axis 34Ax of the corresponding suction unit 34(1) to (6) in the circumferential direction. Therefore, the rotation angles of the rotation exit holes 37a (1) to (6) and the suction heads 36 (1) to (6) around the main axis 30Ax are made to coincide with each other. However, it goes without saying that the angle in the circumferential direction of the main shaft 30Ax at which the rotation outlet hole 37a is formed is not limited to the above example.

図8(a)は、図3におけるD-D断面図、(b)は、図3におけるE-E断面図である。図8(a)に示すように、ステータ38の上面には、周方向における所定の角度の範囲に表面が凹陥没してなる固定バルブ気室381、382、383が形成されている。 8(a) is a sectional view taken along line DD in FIG. 3, and FIG. 8(b) is a sectional view taken along line EE in FIG. As shown in FIG. 8(a), fixed valve air chambers 381, 382, and 383 are formed on the upper surface of the stator 38 by recessing the surface within a predetermined angle range in the circumferential direction.

なお、固定バルブ気室381が設けられた角度範囲:θ1、固定バルブ気室382が設けられた角度範囲:θ2、固定バルブ気室383が設けられた角度範囲:θ3は、適宜、決定することができる。 Note that the angular range in which the fixed valve air chamber 381 is provided: θ1, the angular range in which the fixed valve air chamber 382 is provided: θ2, and the angular range in which the fixed valve air chamber 383 is provided: θ3 should be determined as appropriate. I can do it.

ステータ38の上面の固定バルブ気室381、382、383は、対向する主ロータ37下面の回転出口孔37a(1)~(6)と半径方向の位置が重なるように構成されており、主ロータ37の回転に伴って回転出口孔37aと固定バルブ気室381、382、383とが平面視において重なったとときに、固定バルブ気室381、382、383から回転出口孔37aへの流路が確保される。このように、主ロータ37とステータ38は、主ロータ37の回転に伴う相対的な角度変化によって流路のオン/オフが可能な回転バルブ機構として機能する。 The fixed valve air chambers 381, 382, and 383 on the upper surface of the stator 38 are configured to overlap in radial position with the rotating outlet holes 37a (1) to (6) on the lower surface of the main rotor 37 facing each other. 37, when the rotation outlet hole 37a and the fixed valve air chambers 381, 382, 383 overlap in plan view, a flow path from the fixed valve air chambers 381, 382, 383 to the rotation outlet hole 37a is secured. be done. In this way, the main rotor 37 and the stator 38 function as a rotary valve mechanism that can turn on and off the flow path by changing the relative angle as the main rotor 37 rotates.

また、図8(b)に示すように、ステータ38の固定バルブ気室381、382、383には底面にそれぞれ圧力供給孔381a、382a、383aが開設されており、孔381a、382a、383aは真空配管61を介して真空排気装置60に接続され、圧力供給孔383aは破壊エア配管71を介して真空破壊手段70に接続され、圧力供給孔381aは電磁弁72を介して破壊エア配管71に接続される構成を成す。 Further, as shown in FIG. 8(b), pressure supply holes 381a, 382a, and 383a are provided at the bottom of the fixed valve air chambers 381, 382, and 383 of the stator 38, respectively. The pressure supply hole 383a is connected to the vacuum evacuation device 60 via the vacuum pipe 61, the pressure supply hole 383a is connected to the vacuum break means 70 via the break air pipe 71, and the pressure supply hole 381a is connected to the break air pipe 71 via the electromagnetic valve 72. form a connected configuration.

図9は、吸着ヘッド36の回転角度θと回転出口孔37aに供給される圧力との関係を示す図であって、(b)は、電磁弁27が開いている状態、(c)は、電磁弁27が開いている状態での動作を表す図である。 FIG. 9 is a diagram showing the relationship between the rotation angle θ of the suction head 36 and the pressure supplied to the rotation outlet hole 37a, in which (b) shows a state in which the solenoid valve 27 is open, and (c) shows FIG. 6 is a diagram illustrating the operation when the electromagnetic valve 27 is open.

先ず、角度範囲θ2では、固定バルブ気室382から回転出口孔37aへの流路が確保され、回転出口孔37aから固定バルブ気室382に真空の圧力P1が付勢される。また、角度範囲θ3では、固定バルブ気室383から回転出口孔37aへの流路が確保され、固定バルブ気室383から回転出口孔37aに真空破壊エア(陽圧)が供給されて、真空が解除されて常圧P2が付勢される。 First, in the angle range θ2, a flow path from the fixed valve air chamber 382 to the rotating outlet hole 37a is secured, and vacuum pressure P1 is applied to the fixed valve air chamber 382 from the rotating outlet hole 37a. Further, in the angle range θ3, a flow path from the fixed valve air chamber 383 to the rotary outlet hole 37a is secured, vacuum breaking air (positive pressure) is supplied from the fixed valve air chamber 383 to the rotary outlet hole 37a, and the vacuum is It is released and normal pressure P2 is applied.

さらに、角度範囲θ1では、固定バルブ気室382から回転出口孔37aへの流路が確保され、電磁弁27が閉じている場合には、図9(b)に示すように、回転出口孔37aから固定バルブ気室382に真空の圧力P1が付勢される。 Furthermore, in the angle range θ1, a flow path from the fixed valve air chamber 382 to the rotation outlet hole 37a is secured, and when the solenoid valve 27 is closed, as shown in FIG. Vacuum pressure P1 is applied to the fixed valve air chamber 382 from.

一方、電磁弁27が開いている場合には、図9(c)に示すように、固定バルブ気室383から回転出口孔37aに真空破壊エア(陽圧)が供給されて真空排気が解除されて常圧P2が付勢される。 On the other hand, when the solenoid valve 27 is open, as shown in FIG. 9(c), vacuum breaking air (positive pressure) is supplied from the fixed valve air chamber 383 to the rotary outlet hole 37a, and the evacuation is released. Normal pressure P2 is applied.

以上の構成により、主ロータ37の回転に伴って、回転出口孔37aが角度範囲θ1に存在する場合において、電磁弁27が閉じている場合には、吸着ヘッド36により物品Wが吸着保持され、回転動作により回転出口孔37aが角度範囲θ2に達した場合には、吸着ヘッド36により物品Wの吸着保持が継続され、さらに、回転出口孔37aが角度範囲θ3に到達したときに、吸着ヘッド36による物品Wの吸着保持が解除される。 With the above configuration, as the main rotor 37 rotates, when the rotation outlet hole 37a exists in the angular range θ1 and the electromagnetic valve 27 is closed, the article W is suction-held by the suction head 36, When the rotating exit hole 37a reaches the angle range θ2 due to the rotational operation, the suction head 36 continues to suction and hold the article W, and when the rotating exit hole 37a reaches the angular range θ3, the suction head 36 The adsorption and holding of the article W by the holder is released.

[Transporting means 40]
The transport means 40 is a transport mechanism that transports the article W transferred from the transport means 10 by the transfer means 30 to a subsequent process. In this embodiment, the conveying means 40 is arranged such that its conveying direction is perpendicular to the conveying direction of the conveying means 10. The conveyance means 40 includes a pair of rollers 42, a suction conveyance belt 41 suspended between them, and suction means (not shown) for suctioning the article W.

搬送手段40は、制御部80の指示に基づき移載手段30の動きと連動するように駆動され、物品Wは、吸引搬送ベルト41に所定の間隔を空けて移載され、ベルト面に吸着された状態で、図4における紙面左方から供給され、右方に向けて搬送される(図1、図2、図4、におけるT3)。このとき、物品Wは、搬送方向に対し物品Wの長尺方向を直交させ、小端面を搬送方向に向けた状態で搬送される。 The conveyance means 40 is driven in conjunction with the movement of the transfer means 30 based on instructions from the control unit 80, and the articles W are transferred onto the suction conveyance belt 41 at a predetermined interval and are attracted to the belt surface. In this state, the paper is supplied from the left side of the page in FIG. 4 and is conveyed toward the right (T3 in FIGS. 1, 2, and 4). At this time, the article W is conveyed with the longitudinal direction of the article W perpendicular to the conveyance direction and the small end face facing the conveyance direction.

なお、搬送手段40は、物品Wの流れにおける搬送手段10の後段に配されていればよく、搬送手段40と搬送手段10とのなす角度は上記に限定されるものではない。
[その他]
排出路50は、搬送手段10の後段に配された滑り台機構であり、物品Wの排出路として機能する。検知手段20が、物品Wが適切に通過しなかったことを検知したとき、移載手段30は搬送手段10から当該物品Wを取得して搬送手段40に移載せず、当該物品Wは搬送手段10から排出路50にそのまま排出される。
Note that the conveying means 40 only needs to be disposed downstream of the conveying means 10 in the flow of the articles W, and the angle between the conveying means 40 and the conveying means 10 is not limited to the above.
[others]
The discharge path 50 is a slide mechanism disposed downstream of the conveyance means 10, and functions as a discharge path for the article W. When the detection means 20 detects that the article W has not passed properly, the transfer means 30 does not acquire the article W from the conveyance means 10 and transfer it to the conveyance means 40, and the article W does not pass through the conveyance means. 10 to the discharge path 50 as it is.

真空排気装置60は、吸着ヘッド36に物品Wを吸着保持するための負圧P1を付勢するための真空ポンプであり、真空配管61を介して移載手段30のステータ38に内装された固定バルブ気室381、382、383の圧力供給孔381a、382a、383aに接続されている。 The evacuation device 60 is a vacuum pump for applying a negative pressure P1 for adsorbing and holding the article W on the adsorption head 36, and is connected to a fixed device installed inside the stator 38 of the transfer means 30 via a vacuum piping 61. It is connected to the pressure supply holes 381a, 382a, 383a of the valve air chambers 381, 382, 383.

真空破壊手段70は吸着ヘッド36に真空破壊エアを供給する陽圧供給手段であり、破壊エア配管71を介して移載手段30のステータ38に内装された固定バルブ気室381、383の圧力供給孔381a、383aに接続されている。真空破壊手段70から固定バルブ気室381、383に真空破壊エア(陽圧)が供給されると、負圧P1が解除されて常圧P2が付勢され、吸着ヘッド36による物品Wを吸着保持が解除される。 The vacuum breaking means 70 is a positive pressure supply means that supplies vacuum breaking air to the suction head 36, and supplies pressure to the fixed valve air chambers 381 and 383 installed in the stator 38 of the transfer means 30 via the breaking air piping 71. It is connected to holes 381a and 383a. When vacuum breaking air (positive pressure) is supplied from the vacuum breaking means 70 to the fixed valve air chambers 381 and 383, the negative pressure P1 is released and normal pressure P2 is applied, and the suction head 36 attracts and holds the article W. is canceled.

制御部80は、搬送手段10と、検知手段20と、移載手段30と搬送手段40に電気的に接続され、制御信号を出力して各ユニットの動作を制御する。制御部80は、例えば、一般的なCPU(Central Processing Unit)とRAM(Random Access Memory)と、これらで実行されるプログラムを備えるコンピュータとして実現される。制御部80は、記憶装置等から物品移載装置1にかかる制御プログラムをRAMに読みだして実行することにより、物品移載装置1を構成する各ユニットそれぞれが連関して動作するように制御して、物品移載装置1の機能を実現する。 The control section 80 is electrically connected to the transport means 10, the detection means 20, the transfer means 30, and the transport means 40, and outputs a control signal to control the operation of each unit. The control unit 80 is realized, for example, as a computer including a general CPU (Central Processing Unit), a RAM (Random Access Memory), and a program executed by these. The control unit 80 controls each unit constituting the article transfer device 1 to operate in conjunction with each other by reading out a control program for the article transfer device 1 from a storage device or the like into a RAM and executing it. Thus, the functions of the article transfer device 1 are realized.

(小 括)
以上のとおり、主ロータ37とステータ38からなる回転バルブ機構を用いた物品移載装置1によれば、吸着ヘッド36の回転角度θ1であるときにおいて、検知手段20が、物品Wが適切に通過したことが検知した正規状態においては、電磁弁27が閉じて吸着ヘッド36に負圧P1を付勢することにより、当該物品Wに対し移載手段30は搬送手段10から当該物品を取得して搬送手段40に移載する動作を行うことができる。
(Brief Summary)
As described above, according to the article transfer device 1 using the rotary valve mechanism consisting of the main rotor 37 and the stator 38, when the rotation angle θ1 of the suction head 36 is reached, the detection means 20 detects whether the article W has passed properly. In the normal state in which this is detected, the electromagnetic valve 27 closes and the suction head 36 is energized with negative pressure P1, so that the transfer means 30 acquires the article W from the conveyance means 10. It is possible to carry out an operation of transferring it to the transport means 40.

他方、検知手段20が、物品Wが適切に通過しなかったことを検知した非正規状態においては、電磁弁27を開いて吸着ヘッド36に負圧P1を付勢しない、すなわち、移載手段30は当該物品Wに対し、搬送手段10から当該物品Wを取得して搬送手段40に移載する動作を行わず、当該物品Wは搬送手段10から排出路50に排出される動作が行われる。 On the other hand, in an irregular state in which the detection means 20 detects that the article W has not passed properly, the electromagnetic valve 27 is not opened to apply negative pressure P1 to the suction head 36, that is, the transfer means 30 does not perform the operation of acquiring the article W from the conveyance means 10 and transfer it to the conveyance means 40 for the article W, but performs an operation of discharging the article W from the conveyance means 10 to the discharge path 50.

<物品移載装置1の動作について>
次に、本実施形態の物品移載装置1による、物品Wの移載動作について説明する。
<About the operation of the article transfer device 1>
Next, the transfer operation of the article W by the article transfer device 1 of this embodiment will be explained.

(搬送手段10、検知手段20による搬送動作)
搬送手段10では、搬送方向に直列に配された複数のコンベア11(1)~(5)に、一対の物品Wが一組となり所定の間隔を空けて、図3における紙面左方から右方に向けて搬送される(図1、図2、図3、におけるT1)。このとき、物品Wは、搬送方向と物品Wの長尺方向とを平行にした状態で、一方のエンドシール部L1を搬送方向に向けた状態で搬送される。
(Conveyance operation by conveyance means 10 and detection means 20)
In the conveyance means 10, a pair of articles W are arranged as a set on a plurality of conveyors 11(1) to (5) arranged in series in the conveyance direction with a predetermined interval, and are arranged from the left to the right on the paper in FIG. (T1 in FIGS. 1, 2, and 3). At this time, the article W is conveyed with the conveyance direction and the longitudinal direction of the article W parallel to each other, with one end seal portion L1 facing the conveyance direction.

また、コンベア11は、搬送方向に向かって左右2つのコンベアL、Rに分割されており、コンベアL、Rには、一対の物品Wのそれぞれが1つずつ吸着保持され、一対の物品Wを1単位として搬送される。 Further, the conveyor 11 is divided into two conveyors L and R on the left and right in the conveyance direction, and each of the pair of articles W is sucked and held on each of the conveyors L and R. Conveyed as one unit.

搬送動作では、先ず、検知手段21により、コンベア11(1)の左右のコンベアL、Rに投入される一対の物品Wそれぞれについて、当該物品Wが検知手段21を通過する時刻を検出する。 In the conveyance operation, first, the detection means 21 detects the time at which the article W passes through the detection means 21 for each of the pair of articles W to be thrown onto the left and right conveyors L and R of the conveyor 11(1).

そして、コンベアL、Rによって搬送される物品の何れかに所定時間以上の遅れが検出された場合には、制御部80の指示に基づき後段のコンベア11(1)~(5)の何れか又は全部に対しコンベアL、Rを異なる速度で駆動するような駆動制御がされ、当該遅れの補正が図られる。 When a delay of more than a predetermined time is detected in any of the articles conveyed by conveyors L and R, one of the subsequent conveyors 11(1) to (5) or Drive control is performed to drive the conveyors L and R at different speeds for all of them, and the delay is corrected.

次に、検知手段22により、コンベア16に投入される左右一対の物品Wそれぞれについて、当該物品Wが検知手段22を通過する時刻を検出する。 Next, the detection means 22 detects, for each of the pair of left and right articles W to be thrown onto the conveyor 16, the time at which the article W passes through the detection means 22.

そして、物品の何れかに所定時間以上の遅れが検出され、検知手段20が、物品Wが適切に通過しなかったことを検知した非正規状態においては、制御部80の指示に基づき、後段の移載手段30により、当該一対の物品は搬送手段40に移載することなく、物品Wを通過させて排出路50にそのまま排出する動作を行う。検知手段21において、左右何れかの物品Wの欠品が検出された場合にも同様の動作を行う。 In an irregular state in which a delay of a predetermined time or more is detected in any of the articles and the detection means 20 detects that the article W has not passed properly, the subsequent stage is The transfer means 30 performs an operation of passing the article W and discharging the pair of articles as is into the discharge path 50 without transferring them to the conveyance means 40 . The same operation is performed when the detecting means 21 detects that either the right or left article W is out of stock.

そして、物品の何れにも所定時間以上の遅れが検出されず、検知手段20が、物品Wが適切に通過したことを検知した正規状態においては、制御部80の指示に基づき、後段の移載手段30により、当該一対の物品は搬送手段40に移載する動作を行う。 In a normal state in which no delay of more than a predetermined time is detected for any of the articles and the detection means 20 detects that the article W has passed properly, the transfer is carried out at the subsequent stage based on instructions from the control unit 80. The means 30 performs an operation of transferring the pair of articles to the conveying means 40.

(移載手段30による移載又は排出動作)
主ロータ37は、ステータ38に配されたモータ39によって、主軸30Axの回りを半時計方向(図1、図2、におけるR1)に駆動回転されることで、吸着ユニット34(1)~(6)を主軸30Aを軸として公転させる。
(Transfer or discharge operation by transfer means 30)
The main rotor 37 is rotated counterclockwise (R1 in FIGS. 1 and 2) around the main shaft 30Ax by a motor 39 disposed on the stator 38, so that the suction units 34(1) to (6) ) is caused to revolve around the main axis 30A.

このとき、吸着ユニット34(1)~(6)それぞれは、反時計方向に自転(図1、図2、におけるR2)するように構成されており、その結果、、吸着ユニット34(1)~(6)、およびそれらそれぞれに接続される吸着ヘッド36(1)~(6)は、X-X平面方向の向きを一定に保った状態で、主軸30Axのりを回転(公転)する。 At this time, each of the suction units 34(1) to (6) is configured to rotate counterclockwise (R2 in FIGS. 1 and 2), and as a result, the suction units 34(1) to (6) and the suction heads 36(1) to (6) connected to each of them rotate (revolution) about the main shaft 30Ax while keeping the orientation in the XX plane constant.

吸着ユニット34(1)~(6)のカムフォロア346aがステータ38の外周面に設けられたカム溝38aに沿っては軸方向に往復移動して、吸着ヘッド36を上下に移動させ、主ロータ37の回転角度θが、上述した0度と90度付近において、吸着ヘッド36が物品Wを吸引可能な高さLまで下降し、その前後では物品Wの移載に必要な高さHに上昇する動作を行う。 The cam followers 346a of the suction units 34(1) to (6) reciprocate in the axial direction along the cam grooves 38a provided on the outer peripheral surface of the stator 38, moving the suction head 36 up and down, and the main rotor 37 When the rotation angle θ is around 0 degrees and 90 degrees mentioned above, the suction head 36 descends to a height L at which it can suction the article W, and before and after that, it rises to a height H necessary for transferring the article W. perform an action.

並行して、主ロータ37とステータ38からなる回転バルブ機構をより、吸着ヘッド36による物品Wの移載作が制御される。 In parallel, the transfer operation of the article W by the suction head 36 is controlled by a rotary valve mechanism consisting of a main rotor 37 and a stator 38.

具体的には、主ロータ37の回転に伴って、回転出口孔37aが角度範囲θ1に存在する場合に、電磁弁27が閉じている場合には、吸着ヘッド36により搬送手段10上の物品Wが吸着保持し、回転出口孔37aが角度範囲θ2に達した場合には、吸着ヘッド36により物品Wの吸着保持が維持され、さらに、回転して角度範囲θ3に到達したときに、吸着ヘッド36による物品Wの吸着保持が解除され搬送手段40上に移載する動作が行われる。 Specifically, as the main rotor 37 rotates, when the rotation outlet hole 37a exists in the angular range θ1 and the electromagnetic valve 27 is closed, the suction head 36 removes the article W on the conveying means 10. When the article W is suction-held and the rotating exit hole 37a reaches the angle range θ2, the suction head 36 maintains the suction-holding of the article W, and further, when the article W rotates and reaches the angle range θ3, the suction head 36 The suction and holding of the article W is released, and the operation of transferring it onto the conveyance means 40 is performed.

同時に、検知手段20による物品通過検知結果に基づいて、電磁弁27の動作状態を変更することにより、物品Wを搬送手段10から取得して搬送手段40に移載する移載動作と、移載操作を行わず物品Wを通過させて、搬送手段10から排出路50に排出される動作を選択的に行う動作を行う。 At the same time, by changing the operating state of the electromagnetic valve 27 based on the detection result of the article passage by the detection means 20, a transfer operation of acquiring the article W from the conveyance means 10 and transferring it to the conveyance means 40 and a transfer operation are performed. An operation is performed in which the article W is passed through without any operation and is selectively discharged from the conveying means 10 to the discharge path 50.

具体的には、物品移載装置1により、検知手段20が、物品Wが適切に通過したことを検知した正規状態においては、吸着ヘッド36の回転角度θ1であるときにおいて、電磁弁27が閉じて吸着ヘッド36に負圧P1を付勢することにより、当該物品Wに対し移載手段30は搬送手段10から当該物品を取得して搬送手段40に移載する動作を行う。 Specifically, in a normal state in which the detection means 20 detects that the article W has properly passed through the article transfer device 1, the electromagnetic valve 27 closes when the suction head 36 has a rotation angle θ1. By applying negative pressure P1 to the suction head 36, the transfer means 30 performs an operation to acquire the article W from the conveyance means 10 and transfer it to the conveyance means 40.

他方、検知手段20が、物品Wが適切に通過しなかったことを検知した非正規状態においては、移載手段30は、吸着ヘッド36の回転角度θ1であるときにおいて、電磁弁27を開いて吸着ヘッド36に負圧P1を付勢せず、当該物品Wを搬送手段10から搬送手段40に移載する動作は行わず、当該物品Wをそのまま通過させて、搬送手段10から排出路50に排出される動作を行う。 On the other hand, in an irregular state in which the detection means 20 detects that the article W has not passed properly, the transfer means 30 opens the solenoid valve 27 when the suction head 36 has a rotation angle θ1. The suction head 36 is not energized with negative pressure P1, the article W is not transferred from the conveyance means 10 to the conveyance means 40, and the article W is passed through as it is from the conveyance means 10 to the discharge path 50. Perform the action of being ejected.

<まとめ>
以上、説明したように、実施の形態に係る物品移載装置1は、物品Wを移載する物品移載装置であって、物品Wを搬送する搬送手段10と、搬送手段10上の所定の位置における物品Wの通過を検知可能な検知手段20と、搬送手段10の後段に配された搬送手段40と、搬送手段10の後段、かつ、搬送手段40の前段に配され、物品Wを搬送手段10から搬送手段40に移載可能な移載手段30と、搬送手段10の後段に配された排出路50とを備え、検知手段20が、物品Wが適切に通過したことを検知した正規状態においては、移載手段30は搬送手段10から当該物品Wを取得して搬送手段40に移載し、検知手段20が、物品Wが適切に通過しなかったことを検知した非正規状態においては、移載手段30は搬送手段10から当該物品Wを取得して搬送手段40に移載せず、当該物品Wは搬送手段10から排出路50に排出されることを特徴とする。
<Summary>
As described above, the article transfer device 1 according to the embodiment is an article transfer device that transfers the article W, and includes a conveying means 10 for conveying the article W, and a predetermined position on the conveying means 10. A detection means 20 capable of detecting passage of the article W at a position, a conveyance means 40 disposed after the conveyance means 10, and a conveyance means 40 disposed after the conveyance means 10 and before the conveyance means 40, which convey the article W. It includes a transfer means 30 that can be transferred from the means 10 to the conveyance means 40, and a discharge path 50 arranged at the rear stage of the conveyance means 10, and the detection means 20 detects that the article W has passed properly. In the irregular state, the transfer means 30 acquires the article W from the conveyance means 10 and transfers it to the conveyance means 40, and the detection means 20 detects that the article W has not passed properly. is characterized in that the transfer means 30 does not acquire the article W from the conveyance means 10 and transfer it to the conveyance means 40, but the article W is discharged from the conveyance means 10 to the discharge path 50.

従来の物品移載装置では、前段の供給工程において、コンベアの一部を傾けてピッチ不良の商品を工程外に排出するか、エアブローを用いて工程外に吹き飛ばして排出するといった排出方法が採られていたが、エアブローを用いた排出方法では、正確に商品を排出できない場合があり、また、排出される商品そのものに損傷を与えてしまうといった課題があった。 In conventional article transfer equipment, in the first stage of the supply process, a part of the conveyor is tilted to discharge products with poor pitch to the outside of the process, or an air blower is used to blow the products out of the process. However, the ejection method using air blowing has the problem that the products may not be ejected accurately, and the ejected products themselves may be damaged.

また、コンベアの一部を傾斜する排出方法では、流量が多く搬送速度が速い場合には、搬送周期が短く排出自体行うことが困難になるという課題があった。 Further, in the discharge method in which a part of the conveyor is inclined, when the flow rate is large and the conveyance speed is high, the conveyance period is short and it becomes difficult to perform the discharge itself.

これに対し、実施の形態に係る物品移載装置1では、移載装置の上流の搬送時に工程外排出するのではなく、ピッチ不良が検出された物品Wを移載手段30で移載せずにそのまま通過させるという構成を実現した。 In contrast, in the article transfer device 1 according to the embodiment, instead of discharging the article W from the process during conveyance upstream of the transfer device, the article W in which a pitch defect has been detected is not transferred by the transfer means 30. We achieved a configuration that allows the light to pass through as is.

これにより、搬送手段から別の搬送手段に物品Wを移載する際に、物品Wを選択的に除外することが可能な物品移載装置及び物品移載方法を提供することができる。 Thereby, it is possible to provide an article transfer device and an article transfer method that can selectively exclude the article W when transferring the article W from one conveyance means to another conveyance means.

また、別の態様では、上記何れかに記載の態様において、移載手段30は、主軸30Axの周りを回転可能な回転部材37と、回転部材37に配され、回転部材37の回転に伴って主軸30Axの周りを回転するとともに、主軸30Axに平行な中心軸34Axの周りを自転することにより、回転に伴って主軸30Axに垂直な面内の向きが変化しないように構成された吸着ヘッド36と、吸着ヘッド36に負圧P1を付勢可能な真空排気装置60と、回転部材37の主軸30Axの周りの回転角度に基づき、吸着ヘッド36への負圧P1の付勢及び解除を制御可能であって、回転部材37の主軸30Axの周りの回転角度が、吸着ヘッド36が搬送手段10の上方に位置する第1の角度θ1であるときに吸着ヘッド36に負圧P1又は解除を選択可能であり、吸着ヘッド36が搬送手段40の上方に位置する第2の角度θ3であるときに吸着ヘッド36に負圧P1の解除が可能であり、第1の角度θ1と第2の角度θ3との間の第3の角度θ3であるときに吸着ヘッド36に負圧P1の付勢が可能な、回転バルブ機構37、38とを備え、回転バルブ機構37、38は、回転部材37の主軸30Axの周りの回転角度が第1の角度θ1であるときに、正規状態では吸着ヘッド36に負圧P1が付勢し、非正規状態では吸着ヘッド36に負圧P1を付勢しない構成としてもよい。 In another aspect, in any of the aspects described above, the transfer means 30 is disposed on the rotating member 37 and the rotating member 37 that can rotate around the main axis 30Ax, and the transferring means 30 is arranged on the rotating member 37, and A suction head 36 configured to rotate around a main axis 30Ax and also rotate around a central axis 34Ax parallel to the main axis 30Ax so that its direction in a plane perpendicular to the main axis 30Ax does not change with rotation. , a vacuum evacuation device 60 capable of applying negative pressure P1 to the suction head 36, and the application and release of negative pressure P1 to the suction head 36 can be controlled based on the rotation angle of the rotating member 37 around the main axis 30Ax. Therefore, when the rotation angle of the rotating member 37 around the main axis 30Ax is the first angle θ1 at which the suction head 36 is located above the conveying means 10, it is possible to select negative pressure P1 or release for the suction head 36. The negative pressure P1 can be released to the suction head 36 when the suction head 36 is located at the second angle θ3 above the conveyance means 40, and the first angle θ1 and the second angle θ3 are The rotary valve mechanisms 37 and 38 are equipped with rotary valve mechanisms 37 and 38 that are capable of applying negative pressure P1 to the suction head 36 when the third angle θ3 between When the surrounding rotation angle is the first angle θ1, a configuration may be adopted in which negative pressure P1 is applied to the suction head 36 in a normal state, and negative pressure P1 is not applied to the suction head 36 in an irregular state.

係る構成により、物品移載装置1に物品W吸引時における真空破壊が可能な、回転バルブ機構37、38を用いた構成により、搬送手段10から別の搬送手段40に物品Wを移載する際に、物品Wを選択的に除外することが可能な物品移載装置及び物品移載方法を具体的に実現できる。 With this configuration, the rotary valve mechanisms 37 and 38 that are capable of breaking the vacuum when suctioning the article W in the article transfer device 1 are used. Furthermore, it is possible to concretely realize an article transfer device and an article transfer method that can selectively exclude articles W.

また、別の態様では、上記何れかに記載の態様において、さらに、吸着ヘッド36に陽圧を付勢可能な真空破壊手段70を備え、回転バルブ機構37、38は、回転部材37の主軸30Axの周りの回転角度が第1の角度θ1であるときに、正規状態では吸着ヘッド36に負圧P1を付勢し、非正規状態では吸着ヘッド36に負圧P1及び陽圧を付勢し、回転部材37の主軸30Axの周りの回転角度が第2の角度θ3であるときに吸着ヘッド36に負圧P1及び陽圧を付勢し、回転部材37の主軸30Axの周りの回転角度が第3の角度θ3であるときに吸着ヘッド36に負圧P1を付勢する構成としてもよい。 In another aspect, in any of the aspects described above, the suction head 36 is further provided with a vacuum breaking means 70 capable of applying positive pressure, and the rotary valve mechanisms 37 and 38 When the rotation angle around is a first angle θ1, in a normal state, a negative pressure P1 is applied to the suction head 36, and in an irregular state, a negative pressure P1 and a positive pressure are applied to the suction head 36, When the rotation angle of the rotating member 37 around the main axis 30Ax is the second angle θ3, negative pressure P1 and positive pressure are applied to the suction head 36, and the rotation angle of the rotating member 37 around the main axis 30Ax is the third angle. A configuration may be adopted in which the negative pressure P1 is applied to the suction head 36 when the angle θ3 is.

係る構成により、搬送手段から別の搬送手段に物品を移載する際に、物品Wを選択的に除外することが可能な回転バルブ機構を具体的に実現できる。 With such a configuration, it is possible to concretely realize a rotary valve mechanism that can selectively exclude the article W when transferring the article from one conveyance means to another conveyance means.

A modified example will be described below as an example of such a form.

上記実施の形態に係る物品移載装置1では、搬送手段10では、複数の物品Wが並列に搬送され、移載手段30は、並列に搬送される複数の物品Wを搬送手段40の搬送方向に対し直列に変換して搬送手段40に移載し、搬送手段40では、複数の物品Wが直列に搬送される構成とした。 In the article transfer device 1 according to the embodiment described above, the plurality of articles W are conveyed in parallel in the conveyance means 10, and the transfer means 30 transports the plurality of articles W conveyed in parallel in the conveyance direction of the conveyance means 40. The articles W are converted into series and transferred to the conveyance means 40, and the conveyance means 40 has a configuration in which a plurality of articles W are conveyed in series.

しかしながら、搬送手段10、40における物品Wの搬送形態は製造される商品の形態や梱包形態に合わせて適宜変更してもよい。例えば、搬送手段10では、物品Wが直列に搬送される構成であり、移載手段30は、直列に搬送される物品Wを搬送手段40の搬送方向に対し並列に変換する、あるいは、直列の状態を維持して搬送手段40に移載する構成としてもよい。 However, the manner in which the articles W are conveyed in the conveying means 10 and 40 may be changed as appropriate depending on the form and packaging form of the product to be manufactured.
