図1には本発明の方法が適用されるコイル倉庫の平面図を示す。コイル倉庫には図1の左右方向へ走行する、搬送装置としての操縦室を備えた天井走行クレーン1が設けられている。当該クレーン1の吊り具が移動可能な長方形領域は、左下隅部Oを原点として図の横方向(走行方向)へX軸がとられ、縦方向(横行方向)へY軸がとられている。吊り具によって吊り上げられた荷物としての筒状コイルのX,Y座標位置はそれぞれ、天井走行クレーン1からの走行位置信号と横行位置信号より知ることができる。上記コイル倉庫の床面上には適当なXY座標範囲にゾーンZ1,Z2が設定されており(本実施形態は二つのゾーンが設定されている場合を示す)、これらゾーンZ1,Z2内の適当位置に、後述するように複数のコイルC1,C2,C3、C4が山積み状態で置かれる。   FIG. 1 shows a plan view of a coil warehouse to which the method of the present invention is applied. The coil warehouse is provided with an overhead traveling crane 1 having a cockpit as a transfer device that travels in the left-right direction in FIG. The rectangular region in which the lifting tool of the crane 1 is movable has the X axis in the horizontal direction (traveling direction) in the figure with the lower left corner O as the origin, and the Y axis in the vertical direction (transverse direction). . The X and Y coordinate positions of the cylindrical coil as the load lifted by the lifting tool can be respectively known from the traveling position signal and the traversing position signal from the overhead traveling crane 1. Zones Z1 and Z2 are set in an appropriate XY coordinate range on the floor surface of the coil warehouse (this embodiment shows a case where two zones are set), and appropriate zones in these zones Z1 and Z2 are set. As will be described later, a plurality of coils C1, C2, C3, and C4 are placed in the position in a stacked state.

図2には上記クレーン1の吊り具11を示す。コイル倉庫の床面Fを基準に高さ方向へZ軸がとられており、吊り具11はその脚部を中心開口に挿入してコイルCを吊り上げており、コイルCのZ座標位置は、天井走行クレーン1から出力される吊り具11の巻上げ位置信号から算出される。図2は一対のコイルCを吊り上げた状態を示している。吊り具11の向きはY方向と、反転した−Y方向へ変更可能であり、これは吊り具11の基端12に内設されたエンコーダ(図示略)によって検出される。また、吊り上げたコイルCの重量は上記基端12に内設されたロードセル(図示略)によって検出される。天井走行クレーン1からの上記走行位置信号、横行位置信号、巻上げ位置信号、エンコーダ信号、およびロードセル信号は主コンピュータ(図3)に送信される。   FIG. 2 shows a hanging tool 11 of the crane 1. The Z axis is taken in the height direction with respect to the floor surface F of the coil warehouse, and the lifting tool 11 has its legs inserted into the central opening to lift the coil C. The Z coordinate position of the coil C is It is calculated from the hoisting position signal of the hanger 11 output from the overhead traveling crane 1. FIG. 2 shows a state in which a pair of coils C is lifted. The direction of the hanger 11 can be changed between the Y direction and the inverted −Y direction, and this is detected by an encoder (not shown) provided in the base end 12 of the hanger 11. The weight of the coil C that is lifted is detected by a load cell (not shown) provided in the base end 12. The traveling position signal, the traversing position signal, the hoisting position signal, the encoder signal, and the load cell signal from the overhead traveling crane 1 are transmitted to the main computer (FIG. 3).

トラックT(図1)に積まれたコイルC5を吊り上げる場合には、天井走行クレーン1を所定位置へ移動させて、その吊り具11によって所望のコイルC5を吊り上げる。当該コイルC5の納入先、製品番号、重量等の仕様はコイルC5の表面に付されたバーコードに記されており、吊り上げ前に当該仕様はハンディリーダで読み取られて上記主コンピュータ2(図3)へ送信され、当該コイルC5を識別するためのコイルIDと共に記憶される。ロードセルによって検出された吊り重量が図4に示すように所定値(例えば500Kg)を越えた後、インチングによる重量変動時間(例えば1秒)が経過したときに主コンピュータ2はコイルC5の吊り上げ完了、すなわち搬送開始を判定し、以後は天井走行クレーン1の走行位置信号と横行位置信号、および巻上げ位置信号によって、搬送されるコイルC5のコイルIDと一体に、X,Y,Z座標位置(コイル位置)が追跡され記憶される。   When lifting the coil C5 loaded on the truck T (FIG. 1), the overhead traveling crane 1 is moved to a predetermined position, and the desired coil C5 is lifted by the lifting tool 11. The specifications of the delivery destination, product number, weight, etc. of the coil C5 are written on a barcode attached to the surface of the coil C5. The specifications are read by a handy reader before lifting, and the main computer 2 (FIG. 3). ) And stored together with the coil ID for identifying the coil C5. As shown in FIG. 4, when the weight variation time (for example, 1 second) due to inching has elapsed after the suspended weight detected by the load cell exceeds a predetermined value (for example, 500 kg), the main computer 2 completes lifting of the coil C5. That is, the start of conveyance is determined, and thereafter, the X, Y, Z coordinate position (coil position) is integrated with the coil ID of the coil C5 to be conveyed by the traveling position signal and the traverse position signal of the overhead traveling crane 1 and the winding position signal. ) Is tracked and stored.

トラックTから吊り上げられて天井走行クレーン1で搬送されたコイルC5は、いずれかのゾーンZ1,Z2の適当位置に置かれる。以下は、ゾーンZ1の左半部領域にコイルC1として山積みされる場合について説明する。コイルC5の吊り降ろし完了、すなわち搬送終了は、ロードセルによって検出された吊り重量が図4に示すように所定値(例えば200Kg)より小さくなった後、インチングによる重量変動時間(例えば1秒)が経過したときに主コンピュータ2で判定され、この時のX,Y,Z座標位置がゾーンZ1内に置かれたコイルC1の位置として記憶される。   The coil C5 lifted from the truck T and transported by the overhead traveling crane 1 is placed at an appropriate position in one of the zones Z1 and Z2. The following describes a case where the coil C1 is piled up in the left half region of the zone Z1. When the suspension of the coil C5 is completed, that is, the end of the conveyance, the weight variation time (for example, 1 second) by inching elapses after the suspended weight detected by the load cell becomes smaller than a predetermined value (for example, 200Kg) as shown in FIG. Is determined by the main computer 2, and the X, Y and Z coordinate positions at this time are stored as the position of the coil C1 placed in the zone Z1.

ここで、コイルC1〜C4は各ゾーンZ1,Z2の後縁Z11,Z21から前方へ詰めるように置かれる。最初のコイルC1が置かれると、これを基準に図5に示すような、山積みの列および段を識別するための位置検知領域ARがソフト的に設定される。本実施形態では(1)〜(9)の9列で4段の山積みを行う例を示している。図5中、dは床面から敷板上に置かれた1段目コイルC1の最下位置までの距離、bは列間の距離、wは位置検知領域ARのあそび幅、eは位置検知領域ARのあそび高さである。そして、奇数列には第1段と第3段の境界高さH1が設定され、偶数列には第2段と第4段の境界高さH2が設定される。ゾーンZ1内に置かれたコイルC1はそのX座標位置より、いずれの列に属するかが判定され、またZ座標位置より、いずれの段に属するかが判定されて、主コンピュータ2(図3)にコイルIDと共に記憶される。   Here, the coils C1 to C4 are placed so as to be packed forward from the rear edges Z11 and Z21 of the zones Z1 and Z2. When the first coil C1 is placed, a position detection area AR for identifying a pile and row of piles as shown in FIG. In the present embodiment, an example is shown in which four rows are stacked in nine rows (1) to (9). In FIG. 5, d is the distance from the floor surface to the lowest position of the first stage coil C1 placed on the floor, b is the distance between the columns, w is the play width of the position detection area AR, and e is the position detection area. The height of AR play. Then, the boundary height H1 between the first and third stages is set for the odd-numbered columns, and the boundary height H2 between the second and fourth stages is set for the even-numbered columns. The coil C1 placed in the zone Z1 is determined from which X coordinate position it belongs to which column, and from the Z coordinate position it is determined which stage it belongs to, and the main computer 2 (FIG. 3). Is stored together with the coil ID.

この場合、コイル径の大小不揃い等によって、新たに山積みされるコイルC1のX座標位置ないしZ座標位置が上記位置検知領域ARのあそび幅wやあそび高さcから外れた場合には、クレーン操縦室にエラーが報知されて山積み中止が指示される。なお、図5の紙面垂直方向であるコイルC1の前後(奥行き)位置については、そのY座標位置に基づいてゾーンZ1(図1)の後縁Z11から何番目のコイルであるか(番)が判定される。   In this case, if the X-coordinate position or the Z-coordinate position of the newly piled coil C1 deviates from the play width w or play height c of the position detection area AR due to unevenness of the coil diameter, the crane operation An error is reported to the room and an instruction to stop stacking is given. As for the front and rear (depth) positions of the coil C1 in the direction perpendicular to the paper surface of FIG. 5, the coil number (number) from the rear edge Z11 of the zone Z1 (FIG. 1) is determined based on the Y coordinate position. Determined.

ゾーンZ1に置かれたコイルC1は、その列、段、番に応じて、クレーン操縦室に設けた副コンピュータ3(図3)のモニタ31上に表示される。モニタ画面31aの一例を図6に示す。山積みされたコイルC1は、三次元描画ソフトによって、クレーン1のX,Y,Z座標位置から、列、段、番に応じて配列されたこれらコイルC1を見下ろすような斜視図で、本実施形態では六角筒状のシンボルで描かれる。なお、モニタ画面31a上のシンボルでは、コイル径やコイル幅の相違は描かれない。   The coil C1 placed in the zone Z1 is displayed on the monitor 31 of the sub computer 3 (FIG. 3) provided in the crane cockpit according to the row, stage, and number. An example of the monitor screen 31a is shown in FIG. The piled coils C1 are perspective views looking down on the coils C1 arranged according to the rows, stages, and numbers from the X, Y, Z coordinate positions of the crane 1 by 3D drawing software. Then, it is drawn with a hexagonal cylindrical symbol. It should be noted that the symbols on the monitor screen 31a do not depict differences in coil diameter or coil width.

コイルC1に対して出荷指示があると、主コンピュータ2はモニタ画面31aに描かれた該当するコイルC1のシンボルを点滅表示させて、クレーン操縦者をサポートする。天井走行クレーン1が所定位置へ移動し、その吊り具11によって上記コイルC1を吊り上げると、その吊り重量が検出されて既述のようにコイルC1の吊り上げ完了が判定され、以後は天井走行クレーン1の走行位置信号と横行位置信号、および巻上げ位置信号によって、搬送されるコイルC1のX,Y,Z座標位置が追跡される。この間、クレーン操縦室のモニタ画面31aでは、図6に示すように、吊り具11のシンボルとこれに吊り上げられたコイルC1のシンボルが描かれ表示される。吊り具11によって吊り上げられたコイルC1の数は、吊り重量と、予め記憶されている当該コイルC1の単体重量を比較して判定される。そして、判定された数のコイルC1のシンボルが、モニタ画面31a上に描かれた吊り具11のシンボルに重ねて描かれて、吊られた状態であることが示される。この時、モニタ画面31aの隅部には、吊られたコイルC1の仕様が表示される(図6中のE領域)。   When there is a shipping instruction for the coil C1, the main computer 2 blinks the symbol of the corresponding coil C1 drawn on the monitor screen 31a to support the crane operator. When the overhead traveling crane 1 moves to a predetermined position and the coil C1 is lifted by the lifting tool 11, the lifting weight is detected and the completion of the lifting of the coil C1 is determined as described above. Thereafter, the overhead traveling crane 1 The X, Y, and Z coordinate positions of the coil C1 being conveyed are tracked by the travel position signal, the traverse position signal, and the winding position signal. During this time, on the monitor screen 31a of the crane cockpit, as shown in FIG. 6, the symbol of the lifting tool 11 and the symbol of the coil C1 lifted on this are drawn and displayed. The number of coils C1 lifted by the lifting tool 11 is determined by comparing the suspended weight with a single weight of the coil C1 stored in advance. Then, the determined number of coils C1 symbols are drawn over the symbols of the hanger 11 drawn on the monitor screen 31a to indicate that they are hung. At this time, the specification of the suspended coil C1 is displayed at the corner of the monitor screen 31a (E region in FIG. 6).

このように本実施形態によれば、コイル倉庫のゾーン内の任意位置に山積みされるコイルのX,Y,Z座標位置を、吊り降ろし完了時の天井走行クレーンの走行位置、横行位置および巻上げ位置より認識して、倉庫に保管されたコイルの位置を適正に管理することができる。そして、上記X,Y,Z座標位置より上記コイルの列、段、番を判定して、これに基づいて天井走行クレーンの操縦室内のモニタ画面に、山積み状態のコイルのシンボルを3次元描画することにより、上記クレーンによるコイルの入出荷をスムーズに行うことができる。なお、上記実施形態において、山積みの列数および段数は特に限定されない。また、コイルは必ずしも山積みされる必要はなく、コイル倉庫の床面上に平置きされても良い。また、搬送装置は必ずしも天井走行クレーンである必要はなく、さらに、前後方向(Y方向)への搬送を行わない二次元的なものであっても良い。   As described above, according to the present embodiment, the X, Y, and Z coordinate positions of the coils piled at an arbitrary position in the zone of the coil warehouse are set to the traveling position, the traversing position, and the winding position of the overhead traveling crane when the suspension is completed. Recognizing more, the position of the coil stored in the warehouse can be properly managed. Then, the coil row, step, and number are determined from the X, Y, and Z coordinate positions, and the symbols of the piled coils are three-dimensionally drawn on the monitor screen in the cockpit of the overhead traveling crane based on this. Thus, receipt and shipment of the coil by the crane can be performed smoothly. In the above embodiment, the number of stacked rows and the number of stages is not particularly limited. In addition, the coils are not necessarily piled up, and may be laid flat on the floor of the coil warehouse. In addition, the transport device is not necessarily an overhead traveling crane, and may be a two-dimensional one that does not transport in the front-rear direction (Y direction).
