Description

本発明は、ロール状に巻かれたフィルムや紙等の原反(以下、ワークと呼ぶ)を、保持装置に搬送する無人搬送台車で搬送した際の、保持装置とワークとの位置を調整する装置に関するものであり、特に、中心軸部分が中空状に形成されたワークを保持装置に搬送した際の位置を調整する装置を有する搬送システムに関するものである。   The present invention adjusts the position of a holding device and a workpiece when a raw film (hereinafter referred to as a workpiece) such as a film or paper wound in a roll shape is conveyed by an unmanned conveyance carriage that conveys the material to the holding device. More particularly, the present invention relates to a transport system having a device that adjusts the position when a work having a hollow central shaft portion is transported to a holding device.

従来、ロール状に巻かれたフィルムや紙等のワークを、保持装置に搬送する装置として、床に取り付けられたレール等に沿って移動する無人走行式の台車や、床に配置された磁石の磁気等を認識して移動する無人搬送台車等の搬送装置があり、ワークを保持装置に搬送した後、保持装置に設けられたチャックをワークの中心に挿入可能な位置に移動させる搬送装置が公知である。   Conventionally, as a device for transporting a film or paper work wound in a roll shape to a holding device, an unmanned traveling cart that moves along a rail attached to the floor, or a magnet arranged on the floor 2. Description of the Related Art There is a transfer device such as an unmanned transfer carriage that moves by recognizing magnetism or the like, and a transfer device that moves a chuck provided to the holding device to a position where it can be inserted into the center of the work after transferring the work to the holding device It is.

例えば、特許文献1に記載のロール自動供給装置は、中空のコア210を有したワーク(原反ロール200)と、ワーク(原反ロール200)の両端から突出したコア210の突出部を、無人搬送台車(AGV100)に搭載されたアーム110の受け部で下方から支持してワーク(原反ロール200)をワーク保持装置(チャッキング装置300)まで搬送するものであり、ワーク保持装置(チャッキング装置300)は、ワーク(原反ロール200)のコア210の中空部に入り込むことのできるコーン(チャック)で、無人搬送台車(AGV100)からワーク(原反ロール200)を受け取るものである。   For example, a roll automatic supply device described in Patent Document 1 includes a workpiece having a hollow core 210 (raw fabric roll 200) and a protruding portion of the core 210 protruding from both ends of the workpiece (raw fabric roll 200). A workpiece (original fabric roll 200) is supported from below by a receiving portion of an arm 110 mounted on a transport carriage (AGV100) and transports to a workpiece holding device (chucking device 300). The workpiece holding device (chucking) The apparatus 300) is a cone (chuck) that can enter the hollow portion of the core 210 of the workpiece (raw fabric roll 200) and receives the workpiece (original fabric roll 200) from the automatic guided vehicle (AGV100).

この特許文献1等で公知のロール自動供給装置は、さらに、無人搬送台車(AGV100)のリフタ(搭載部)を上下方向に駆動する上下方向駆動機構と水平方向に駆動する水平方向駆動機構とを有し、ワーク(原反ロール200)が移載される位置を確認するためのレーザ光源10及び受光部となるPSD20等の検出手段で構成された検出装置からの信号で、受光位置の基準位置からのズレ量を算出し、算出されたズレ量をなくすように上下方向駆動機構および水平方向駆動機構(芯合せ駆動機構およびリフタ駆動機構)を位置決め制御回路で制御しているため、無人搬送台車(AGV100)とワーク保持装置(チャッキング装置)との位置ズレを上下方向駆動機構及および水平方向駆動機構(芯合せ駆動機構およびリフタ駆動機構)で微調整し、原反ロールの受け渡しを確実に実施できるようにしたものである。   This automatic roll feeder known in Patent Document 1 and the like further includes a vertical drive mechanism for driving the lifter (mounting portion) of the automatic guided vehicle (AGV100) in the vertical direction and a horizontal drive mechanism for driving in the horizontal direction.

ところが、上記特許文献等で公知のロール自動供給装置は、未だ改善の余地があった。   However, the roll automatic feeding device known in the above-mentioned patent documents still has room for improvement.

すなわち、特許文献1で公知のロール自動供給装置は、無人搬送台車がワーク保持装置に移動した後のワークとワーク保持装置との位置ズレの微調整のみ実施可能な構成のため、無人搬送台車の移動位置は別途設定する必要があるとともに、無人搬送台車がワーク保持装置に移動する度に位置の確認及び位置ズレの調整を実施するため、作業効率が悪化する虞があった。
また、ワーク保持装置側にレーザ光源等の位置ズレを確認するための機器を取り付ける必要があるため、無人搬送台車側以外に配線を施す必要や、ワーク保持装置側と無人搬送台車側とで通信可能な構成にする必要があり、装置構成が複雑化する虞があった。
That is, the roll automatic feeding device known in Patent Document 1 has a configuration that can only perform fine adjustment of the positional deviation between the workpiece and the workpiece holding device after the automated guided cart moves to the workpiece holding device. The moving position needs to be set separately, and every time the automatic guided carriage moves to the work holding device, the position is confirmed and the positional deviation is adjusted, so that the work efficiency may be deteriorated.
In addition, it is necessary to install equipment for checking the positional deviation of the laser light source etc. on the work holding device side, so it is necessary to provide wiring on the side other than the automatic guided carriage side, and communication between the work holding device side and the automatic guided carriage side It is necessary to make the configuration possible, and there is a possibility that the device configuration becomes complicated.

さらに、実際にワークを無人搬送台車上に載置した状態での調整作業となるため、無人搬送台車とワーク保持装置との位置ズレの程度によっては、ワークがワーク保持装置に衝突したり、作業者にぶつかる等の事故が発生する虞があった。   Furthermore, since the work is actually adjusted with the work placed on the automatic guided carriage, depending on the degree of misalignment between the automatic guided carriage and the work holding device, the work may collide with the work holding device, There was a risk of accidents such as hitting a person.

本発明は、これらの問題点を解決するものであり、簡単な構成で、無人搬送台車にワークを載置することなく、ワークをワーク保持装置に渡す際の位置ズレの調整が、実際のワーク搬送作業よりも前に完結する搬送位置調整装置を提供することを目的とするものである。   The present invention solves these problems, and it is possible to adjust the positional deviation when passing the workpiece to the workpiece holding device with a simple configuration without placing the workpiece on the automatic guided carriage. It is an object of the present invention to provide a transport position adjusting device that is completed before a transport operation.

本発明の搬送システムは、中心が中空であるロール状のワークを保持可能なコーンを有する保持アームが設けられたワーク保持装置に、水平方向および高さ方向に移動可能なリフタ上に保持した前記ワークを搬送する無人搬送台車と、前記無人搬送台車の搬送位置を調整する搬送位置調整装置とを有する搬送システムであって、前記搬送位置調整装置は、前記リフタに着脱可能に構成された調整冶具と、制御部とを有し、前記調整冶具には、前記リフタに相対位置を固定して接続可能に構成されたベース部材が設けられ、前記ベース部材は、端面確認部材と、コーン検出センサとを有し、前記端面確認部材は、前記リフタに載置した際の前記ワークの両端面の少なくとも一方の位置を指示可能に構成され、前記コーン検出センサは、前記コーンの位置を検出可能に構成され、前記無人搬送台車には、前記ワークの両端面の少なくとも一方の位置を検出可能に構成された端面検出センサが設けられ、前記制御部は、前記コーン検出センサと、前記端面検出センサとからの情報を取得・処理可能に構成されているとともに、前記リフタの移動位置を前記無人搬送台車に指示可能に構成されていることにより、前記課題を解決するものである。   The conveyance system of the present invention is the above-mentioned work holding device provided with a holding arm having a cone capable of holding a roll-shaped work having a hollow center, and held on a lifter that can move in a horizontal direction and a height direction. A transport system having an unmanned transport cart for transporting a workpiece and a transport position adjusting device for adjusting a transport position of the unmanned transport cart, wherein the transport position adjusting device is configured to be detachable from the lifter. And a control unit, and the adjustment jig is provided with a base member configured to be connectable with a fixed relative position to the lifter, the base member comprising an end face confirmation member, a cone detection sensor, The end surface confirmation member is configured to be capable of indicating the position of at least one of both end surfaces of the workpiece when placed on the lifter, and the cone detection sensor The automatic guided vehicle is provided with an end surface detection sensor configured to detect at least one position of both end surfaces of the workpiece, and the control unit includes the cone detection sensor and the cone detection sensor. The above-mentioned problem is solved by being configured to be able to acquire and process information from the end face detection sensor and to be able to instruct the unmanned transport cart for the movement position of the lifter. .

請求項1に係る発明の搬送システムは、リフタに着脱可能に構成された調整冶具を有しており、調整冶具には、端面確認部材が設けられており、無人搬送台車には、端面検出センサが設けられているため、端面検出センサで端面確認部材を検出することで、ワークをリフタに載置することなく、リフタ上のワーク端面の基準位置を特定することができる。
また、調整冶具には、コーン検出センサが設けられているため、ワーク移載位置でリフタを移動させてコーンをコーン検出センサで検出するとともに、コーン検出センサとワークの中空部との位置関係を計算することで、ワークをリフタに載置することなく、ワークの中空部にコーンが進入可能な受け渡し位置を特定することができる。
The conveyance system of the invention according to claim 1 has an adjustment jig configured to be detachable from the lifter, the adjustment jig is provided with an end face confirmation member, and the automatic conveyance carriage has an end face detection sensor. Since the end face detection member is detected by the end face detection sensor, the reference position of the work end face on the lifter can be specified without placing the work on the lifter.
Since the adjustment jig is provided with a cone detection sensor, the lifter is moved at the workpiece transfer position to detect the cone with the cone detection sensor, and the positional relationship between the cone detection sensor and the hollow portion of the workpiece is determined. By calculating, it is possible to specify the delivery position where the cone can enter the hollow portion of the workpiece without placing the workpiece on the lifter.

さらに、制御部は、コーン検出センサと、端面検出センサとからの情報を取得・処理可能に構成されているとともに、リフタの移動位置を無人搬送台車に指示可能に構成されているため、コーン検出センサと端面検出センサとが検出したデータを制御部が自動的に処理し、無人搬送台車にリフタの移動量を伝達することで、人の手を介することなく無人搬送台車の設定ができ、作業効率が向上するとともに、誤入力等の心配がない。
また、ワークの代わりに調整冶具を無人搬送台車に載置して予めリフタの移動位置を調整するため、実際のワークの搬送作業の度にコーンの位置を確認しながらリフタを移動させる必要がなく、迅速に搬送作業を進めることができる。
In addition, the control unit is configured to be able to acquire and process information from the cone detection sensor and the end surface detection sensor, and is configured to be able to instruct the unmanned transport cart for the lifter movement position. The control unit automatically processes the data detected by the sensor and the end face detection sensor and transmits the movement amount of the lifter to the unmanned transport cart, so that the unmanned transport cart can be set without human intervention. The efficiency is improved and there is no worry about incorrect input.
In addition, since the adjustment jig is placed on the automatic guided carriage instead of the workpiece and the lifter movement position is adjusted in advance, there is no need to move the lifter while checking the cone position every time the workpiece is transferred. It is possible to proceed with the conveyance work quickly.

また、通信が必要な構成が全て無人搬送台車および調整冶具上に設けられているため、各部への通信に必要な配線が簡素化でき、複数のワーク保持装置に対しても、無人搬送台車のリフタ上に調整冶具を取り付けるのみで簡単に調整作業を実施できる。
また、端面確認部材は端面検出センサでワークの端面を確認する際に検出するワークの端面の一部として認識されるように設けられていればよく、コーン検出センサは調整冶具側からコーンを検出可能な位置に設けられていればよく、実際のワークに比べて調整冶具は軽くサイズも小さく構成できるため、無人搬送台車のワーク保持装置への進入位置の調整が不十分な場合でも、ワークに比べて調整冶具がワーク保持装置へ衝突したり、作業者にぶつかる等の事故の発生を抑えることができる。
In addition, since all the components that require communication are provided on the automatic guided carriage and the adjustment jig, wiring required for communication to each part can be simplified, and even for a plurality of workpiece holding devices, Adjustment work can be performed simply by attaching an adjustment jig on the lifter.
Further, the end face confirmation member may be provided so as to be recognized as a part of the end face of the work to be detected when the end face detection sensor confirms the end face of the work, and the cone detection sensor detects the cone from the adjustment jig side. The adjustment jig can be configured to be lighter and smaller than the actual workpiece, so that it can be applied to the workpiece even when the position of the unmanned transport cart entering the workpiece holding device is not sufficiently adjusted. In comparison, it is possible to suppress the occurrence of an accident such as the adjustment jig colliding with the work holding device or hitting the operator.

なお、本実施形態において、制御部118は、コーン検出センサ114、端面検出センサ203、中空部検出センサ303から情報を取得・処理し、リフタ202に移動量を指示可能に構成されているものとする。
Next, a method for correcting the movement position of the lifter 202 using the transport position adjusting device 100 of the transport system of the present invention will be described with reference to FIGS.
In the present embodiment, the control unit 118 is configured to be able to acquire and process information from the cone detection sensor 114, the end surface detection sensor 203, and the hollow part detection sensor 303 and to instruct the movement amount to the lifter 202. To do.

まず、図4乃至図7に示すように、補正冶具400を用いて、無人搬送台車200がワーク保持装置300に進入した際の、リフタ202の移動位置を補正する。
始めに、無人搬送台車200のリフタ202に、搬送位置調整装置100を、リフタ202との相対位置が固定されるように載置する。
First, as shown in FIGS. 4 to 7, the correction jig 400 is used to correct the movement position of the lifter 202 when the automatic guided carriage 200 enters the work holding device 300.
First, the transport position adjusting device 100 is placed on the lifter 202 of the automatic guided vehicle 200 so that the relative position to the lifter 202 is fixed.

次に、無人搬送台車200の本体部201上の端面検出センサ203から照射された端面検知用レーザL1で、端面確認部材113を捉えて、端面確認部材113が示すワークWの端面が適正な位置になるように、リフタ202を移動させる。
なお、このときのリフタ202の移動後の位置を、補正基準点と呼ぶ。
Next, the end face detection member 113 is captured by the end face detection laser L1 emitted from the end face detection sensor 203 on the main body 201 of the automatic guided carriage 200, and the end face of the workpiece W indicated by the end face check member 113 is in an appropriate position. The lifter 202 is moved so that
Note that the position after the movement of the lifter 202 at this time is referred to as a correction reference point.

次に、無人搬送台車200を補正冶具400内に、予め床面に貼り付けた無人搬送台車200が認識可能なテープ等を基準として進入させた後、コーン検出センサ114でダミーコーン401を捉え、コーン検出センサ114の中心とダミーコーン401の中心とが、コーン検出センサ114のシートレーザS照射方向の中心線上に位置するように、且つ、コーン検出センサ114からダミーコーン401までの距離が、ワークWの端面がワーク保持装置300に接触しない適正な位置になるように、リフタ202を補正基準点から移動する。   Next, after the unmanned transport cart 200 is entered into the correction jig 400 with reference to a tape or the like that can be recognized by the unmanned transport cart 200 that has been attached to the floor in advance, the cone detection sensor 114 captures the dummy cone 401, The distance from the cone detection sensor 114 to the dummy cone 401 is such that the center of the cone detection sensor 114 and the center of the dummy cone 401 are positioned on the center line of the cone detection sensor 114 in the sheet laser S irradiation direction. The lifter 202 is moved from the correction reference point so that the end face of W is in an appropriate position so as not to contact the work holding device 300.

具体的なダミーコーン401の中心の検出方法としては、図7に示すように、コーン検出センサ114からシート状に照射したシートレーザSが、シートレーザSのどの位置に物体を捉えているか検出可能であるため、ダミーコーン401のシートレーザS展開方向(水平方向)の位置を検出するとともに、三角形と長方形が並んだ形のダミーコーン401先端部にシートレーザSを照射することで、第一検出距離Xおよび第二検出距離Yをコーン検出センサ114で確認することができ、第一検出距離Xと第二検出距離Yとの関係から、より精度よくダミーコーン401の中心を特定することができる。   As a specific method of detecting the center of the dummy cone 401, as shown in FIG. 7, it is possible to detect at which position of the sheet laser S the sheet laser S irradiated in a sheet form from the cone detection sensor 114 is captured. Therefore, the position of the dummy cone 401 in the developing direction (horizontal direction) of the sheet laser S is detected, and the front end portion of the dummy cone 401 in which a triangle and a rectangle are arranged is irradiated with the sheet laser S, whereby the first detection is performed. The distance X and the second detection distance Y can be confirmed by the cone detection sensor 114, and the center of the dummy cone 401 can be identified more accurately from the relationship between the first detection distance X and the second detection distance Y. .

このとき、コーン検出センサ114の中心と中空部確認部材115の検出孔116の中心との位置関係がわかっていれば、リフタ202を移動して検出孔116の中心をダミーコーン401に対する適正な受け渡し位置に合わせることができる。
なお、このときのリフタ202の移動後の位置を、仮受け渡し基準点と呼ぶ。
At this time, if the positional relationship between the center of the cone detection sensor 114 and the center of the detection hole 116 of the hollow portion confirmation member 115 is known, the lifter 202 is moved to appropriately transfer the center of the detection hole 116 to the dummy cone 401. Can be adjusted to the position.
The position after the movement of the lifter 202 at this time is referred to as a temporary delivery reference point.

これによって、補正冶具400に対するリフタ202の補正が完了となり、リフタ202の補正が完了した無人搬送台車200は、補正基準点から仮受け渡し基準点までの移動量をリフタ202に指示することのみで、コーン検出センサ114での確認の必要なく、リフタは検出孔116の中心をダミーコーン401に対する適正な受け渡し位置に繰り返し合わせることができる。   As a result, the correction of the lifter 202 with respect to the correction jig 400 is completed, and the automatic guided vehicle 200 that has completed the correction of the lifter 202 only instructs the lifter 202 to move from the correction reference point to the temporary delivery reference point. The lifter can repeatedly adjust the center of the detection hole 116 to an appropriate delivery position with respect to the dummy cone 401 without the need for confirmation by the cone detection sensor 114.

また、複数の無人搬送台車200に同様の補正を実施することで、補正冶具400のダミーコーン401に対して、全ての無人搬送台車200が、無人搬送台車200ごとの固体差やクセに関係なく、同じ位置に検出孔116を移動することができる。
すなわち、全ての無人搬送台車200が、ワークWをダミーコーン401に対する適正な受け渡し位置に繰り返し合わせることができる。
Further, by performing the same correction on the plurality of automatic guided vehicles 200, all the automatic guided vehicles 200 can be applied to the dummy cone 401 of the correction jig 400 regardless of individual differences or habits of the automatic guided vehicles 200. The detection hole 116 can be moved to the same position.
That is, all the automatic guided vehicles 200 can repeatedly align the workpiece W with an appropriate delivery position with respect to the dummy cone 401.

次に、補正冶具400での補正が完了した無人搬送台車200を用いた、ワーク保持装置300へのワークWの受け渡し位置の調整方法について、図8乃至図11を用いて説明する。
始めに、無人搬送台車200のリフタ202に、搬送位置調整装置100を、リフタ202との相対位置が固定されるように載置する。
Next, a method for adjusting the delivery position of the workpiece W to the workpiece holding device 300 using the automatic guided carriage 200 that has been corrected by the correction jig 400 will be described with reference to FIGS.
First, the transport position adjusting device 100 is placed on the lifter 202 of the automatic guided vehicle 200 so that the relative position to the lifter 202 is fixed.

次に、図8に示すように、無人搬送台車200の本体部201上の端面検出センサ203から照射された端面検知用レーザL1で、端面確認部材113を捉え、端面確認部材113が示すワークWの端面が適正な位置になるように、リフタ202を移動させる。
なお、このときのリフタ202の移動後の位置を、調整基準点と呼ぶ。
Next, as shown in FIG. 8, the end face detection member 113 is captured by the end face detection laser L1 emitted from the end face detection sensor 203 on the main body 201 of the automatic guided carriage 200, and the workpiece W indicated by the end face check member 113 is displayed. The lifter 202 is moved so that the end face of the head becomes an appropriate position.
The position after the movement of the lifter 202 at this time is referred to as an adjustment reference point.

次に、中空部検出センサ303から照射された中空部検知用レーザL2で、中空部確認部材115の検出孔116を捉え、検出孔116の中心が中空部検出センサ303の中空部検知用レーザL2照射中心線上に位置するようにリフタ202で移動することで、検出孔116(ワークWの中空部Cの中心)をコーン302に対する適正な受け渡し位置に移動する際の、リフタ202の高さ方向の移動量を特定できる。
また、調整冶具110の両端面に設けられた検出孔116を中空部検知用レーザL2で同時に捉えることで、ワーク保持装置300と調整冶具110(ワークW)との傾き方向のズレを解消することができる。
Next, the detection hole 116 of the hollow portion confirmation member 115 is captured by the hollow portion detection laser L2 emitted from the hollow portion detection sensor 303, and the center of the detection hole 116 is the hollow portion detection laser L2 of the hollow portion detection sensor 303. By moving with the lifter 202 so as to be positioned on the irradiation center line, the height of the lifter 202 when moving the detection hole 116 (center of the hollow portion C of the workpiece W) to an appropriate delivery position with respect to the cone 302 is increased. The amount of movement can be specified.
Also, by detecting the detection holes 116 provided on both end faces of the adjustment jig 110 simultaneously with the hollow portion detection laser L2, the displacement in the tilt direction between the workpiece holding device 300 and the adjustment jig 110 (work W) can be eliminated. Can do.

次に、図9乃至図10に示すように、無人搬送台車200をワーク保持装置300内に、予め床面に貼り付けた無人搬送台車200が認識可能なテープ等を基準として進入させた後、コーン検出センサ114でコーン302を捉え、コーン検出センサ114の中心とコーン302の中心とが、コーン検出センサ114のシートレーザS照射方向の中心線上に位置するように、且つ、コーン検出センサ114からコーン302までの距離が、ワークWの端面がワーク保持装置300に接触しない適正な位置になるように、リフタ202を調整基準点から移動する。
このとき、コーン検出センサ114の中心と中空部確認部材115の検出孔116の中心との位置関係がわかっていれば、リフタ202を移動して検出孔116の中心をコーン302に対する適正な受け渡し位置に合わせることができる。
なお、このときのリフタ202の移動後の位置を、本受け渡し基準点と呼ぶ。
Next, as shown in FIG. 9 to FIG. 10, after the automatic guided carriage 200 is entered into the work holding device 300 on the basis of a tape or the like that can be recognized by the automatic guided carriage 200 that has been pasted on the floor surface in advance, The cone detection sensor 114 captures the cone 302 so that the center of the cone detection sensor 114 and the center of the cone 302 are positioned on the center line of the cone detection sensor 114 in the sheet laser S irradiation direction, and from the cone detection sensor 114. The lifter 202 is moved from the adjustment reference point so that the distance to the cone 302 is an appropriate position where the end surface of the work W does not contact the work holding device 300.
At this time, if the positional relationship between the center of the cone detection sensor 114 and the center of the detection hole 116 of the hollow portion confirmation member 115 is known, the lifter 202 is moved so that the center of the detection hole 116 is properly transferred to the cone 302. Can be adapted to
Note that the position after the movement of the lifter 202 at this time is referred to as a final delivery reference point.

これによって、ワーク保持装置300に対するリフタ202の調整は完了となり、仮受け渡し基準点と本受け渡し基準点とのズレ量を特定し、リフタ202の補正が完了した全ての無人搬送台車200の仮受け渡し基準点に本受け渡し基準点とのズレ量分の調整をすることで、全ての無人搬送台車200が本受け渡し基準点に検出孔116の中心を移動させることができ、実際の搬送作業に取り掛かるまでの準備に必要な時間を削減できる。
すなわち、全てのリフタ202補正済みの無人搬送台車200が、本受け渡し基準点にワークWを繰り返し移動させることができる。
また、無人搬送台車200を繰り返し移動して連続的にワークWの搬送作業を行う場合でも、その都度コーン302の位置を確認しながらリフタ202を移動させる必要はなく、迅速に搬送作業を進めることができる。
Thereby, the adjustment of the lifter 202 with respect to the work holding device 300 is completed, the amount of deviation between the temporary delivery reference point and the final delivery reference point is specified, and the temporary delivery reference of all the automatic guided carriages 200 for which the lifter 202 has been corrected. By adjusting the amount of deviation from the actual delivery reference point to the point, all the automatic guided vehicles 200 can move the center of the detection hole 116 to the actual delivery reference point, and the actual transportation work is started. The time required for preparation can be reduced.
That is, all the lifter 202 corrected automatic guided carts 200 can repeatedly move the workpiece W to the final delivery reference point.
Further, even when the automatic guided carriage 200 is repeatedly moved to continuously carry the work W, it is not necessary to move the lifter 202 while checking the position of the cone 302 each time, and the carrying work can be carried out quickly. Can do.

さらに、実際にワークWをリフタ202に載せて搬送位置を調整する場合に比べて、ワークWよりも小さく軽い搬送位置調整装置100をリフタ202に載置して調整するため、無人搬送台車200のワーク保持装置300へ最初に進入する際の位置の調整が不十分であっても、搬送位置調整装置100がワーク保持装置300へ衝突したり、作業者にぶつかる等の事故の発生を抑えることができる。   Furthermore, compared with the case where the workpiece W is actually placed on the lifter 202 and the conveyance position is adjusted, the conveyance position adjusting device 100 that is smaller and lighter than the workpiece W is placed on the lifter 202 for adjustment. Even if the position adjustment at the time of first entering the work holding device 300 is insufficient, the occurrence of an accident such as the conveyance position adjusting device 100 colliding with the work holding device 300 or hitting an operator can be suppressed. it can.
