- the transfer control device 160 controls the first transfer device 110 and the second transfer device 120 to pick up the object 200 in parallel in the first area 201 and run in parallel along the rail 130, and then The first transfer device 110 and the second transfer device 120 are controlled to release the objects 200 in the two areas 202 in parallel. That is, the operation of the first transfer device 110 picking the object 200 in the first area 201 and the operation of the second transfer device 120 picking the object 200 in the first area 201 are at least temporarily parallel. The first transfer device 110 and the second transfer device 120 are controlled so that they are carried out (preferably simultaneously).

Further, following such control, an operation of releasing the object 200 held by the first transfer device 110 in the second area 202, and an operation of releasing the object 200 held by the second transfer device 120 into the second area
- the first transfer device 110 and the second transfer device 120 are controlled so that the releasing operation in step 202 is performed at least temporarily in parallel (preferably simultaneously).
- the first transfer device 110 and the second transfer device 120 are individually controlled, for example, even if the picking of the object 200 in the first area 201 of the first transfer device 110 is completed, the picking of the object 200 in the first area 201 of the second transfer device 120 is controlled individually. There is a possibility that the first transfer device 110 may not be able to start traveling toward the second area 202 because it has to wait until the picking of the object 200 is completed.
- the above-mentioned control picks the object 200 in the first area 201, runs parallel to the rail 130, and then releases the object 200 in the second area 202.
- the object 200 is picked and released at different timings by performing a series of operations in parallel as if the first transfer device 110 and the second transfer device 120 were operating synchronously.

If the distance between the object 211 and the second target object 212 is equal to or greater than the first distance 221, the pick determination unit 165 determines that it is possible to pick, and if it is less than the first distance 221, it determines that it is impossible to pick. Further, as shown in FIG.
- the first holding device 113 and the second holding device 123 are lined up in a horizontal plane in a direction perpendicular to the extending direction of the rail 130 (Y-axis direction in the figure) and are closest to each other. If the second distance 222 or more is the distance between the first object 211 and the second object 212 that can be held, the pick determination unit 165 determines that the pick is possible, and if it is less than the second distance 222, the pick is not possible. It may be determined that it is possible. Furthermore, as shown in FIG. 7, if the first object 211 and the second object 212 overlap in the vertical direction (Z-axis direction in the figure), it may be determined that picking is impossible. Furthermore, as shown in FIG.
- the center of gravity of the lower object 200 is higher than that of the upper object. If it is not hidden in 200, it may be determined that it can be picked.
- the holding target setting unit 166 determines the pick order of the target objects 200 placed in the first area 201 and sets the first target object 211 and the second target object 212. Specifically, the retention target setting unit 166 sets the initial value of the variable N (N is an integer of 2 or more) to 2, and selects the first height target at the highest height position determined by the position derivation unit 164. and the N-th height target located at the N-th highest position, and the pick determination unit 165 determines that the first height target and the N-th height target can be picked in parallel. The first height target object determined to be pickable and the Nth target object are set as the first target object 211 and the second target object 212.

- the first transfer device 110 and the second transfer device 120 perform at least part of a series of holding operations for moving the object 200 to a predetermined location at the same time.
- the pick control unit 161 executes a series of holding operations almost synchronously with a time difference of one to several times the control period. Specifically, the pick control unit 161 controls the operation of the first upper arm drive unit 117, the first forearm drive unit 119, the second upper arm drive unit 127, and the second forearm drive unit 129. , to pick the first object 211 and the second object 212 in parallel.

- the case where the pick determining unit 165 determines that parallel picking is not possible means that the pick determining unit 165 repeatedly performs the above-described determination until the variable N reaches the maximum value. This refers to a case where it is determined that it is not possible to pick the object in parallel with the N-th height object determination.
- the first target object 211 and the second target object 212 are the target objects 200 that are selected as targets of the holding operation among the target objects 200 arranged in the first area 201.

- the transfer control device 160 controls the operations of the first transfer device 110 and the second transfer device 120 so that the first holding device 113 and the second holding device 123 do not interfere (contact). Specifically, the second transfer device 120 in the extending direction is moved from the first normal stop position where the first holding device 113 can be stopped when the first transfer device 110 continues to decelerate at the maximum deceleration. The position in which the specified margin distance is added to the side is further in the extending direction than the second normal stop position where the second holding device 123 can stop when the second transfer device 120 continues to decelerate at the maximum deceleration. The driving of the first transfer device 110 and the second transfer device 120 is controlled so as not to be on the second transfer device 120 side.

This is the distance to the stopping position of the first holding device 113 when stopping at the shortest stopping distance.
- the shortest stopping distance of the second transfer device means that the second transfer device 120 continues to decelerate at the maximum deceleration and stops at the shortest stopping distance from the current position of the second transfer device 120 (second holding device 123). This is the distance to the stop position of the second holding device 123 when

- Proximity mode refers to the first transfer mode when the relative distance in the extending direction of the two objects 200 to be picked by the first transfer device 110 and the second transfer device 120 is less than the predetermined threshold. This is a mode in which the loading device 110 and the second transfer device 120 are stopped at a distance shorter than the normal stopping distance. For example, the first transfer device stops at a normal stopping distance between the first object 211 to be picked and the second object 212 to be picked acquired from the position derivation unit 164 in the extending direction of the rail 130. 110 and the distance that cannot be maintained by the second transfer device 120, the normal mode shifts to the close mode.

前記位置導出部から取得したピック対象である2つの対象物の位置に基づき、当該2つの対象物を前記第一移載装置および前記第二移載装置が並行してピック可能か否かを判定するピック判定部を備え、
前記移載制御装置は、前記ピック判定部の判定が肯定される場合には、前記第一移載装置および前記第二移載装置が並行して前記2つの対象物をピックするように前記第一移載装置および前記第二移載装置を制御する一方、前記ピック判定部の判定が否定される場合には、前記第一移載装置が前記第一領域における前記2つの対象物の一方をピックした後、前記第二移載装置が前記第一領域における前記2つの対象物の他方をピックするように前記第一移載装置および前記第二移載装置を制御する
請求項1に記載のピッキング装置。 - 前記位置導出部は、前記第一領域における複数の対象物の鉛直方向の位置および前記軌条の延在方向の位置を判定するものであり、
前記ピック判定部は、Nの初期値を2として、前記位置導出部により判定された鉛直方向の位置が最も高い位置にある第一高さ対象物と、N番目に高い位置にある第N高さ対象物とを、前記第一移載装置および前記第二移載装置が並行してピックできるか否かを判断し、
当該判断が肯定される場合には、前記第一移載装置および前記第二移載装置が並行して前記第一高さ対象物および前記第N高さ対象物をピックするように前記移載制御装置が前記第一移載装置および前記第二移載装置を制御する一方、前記判断が否定される場合には、前記ピック判定部がNに1を加算した後に前記の処理を繰り返す
請求項5に記載のピッキング装置。 - 前記ピック判定部は、
前記第一領域における2つの対象物が鉛直方向に重なっている場合に並行ピック不可能と判定する
請求項5または6に記載のピッキング装置。
