Description

本発明は、段積みされた複数の容器から下方の容器を１個ずつばらして搬送コンベヤへ払い出す容器の段ばらし装置に関する。 The present invention relates to a container leveling device that separates a lower container one by one from a plurality of stacked containers and delivers them to a conveyor.

従来、バケットの左右の把手に係合自在となり且つ所定方向に開閉自在な一対のハンガアームと、このハンガアームを上下動させるアーム昇降シリンダユニットと、ハンガアームが所定の高さ位置まで降下したタイミングでハンガアームを開かせるローラ機構と、このローラ機構によるハンガアームの開閉高さ位置を変えるローラタイミング変更手段を備えたバケットの払出し装置がある。 Conventionally, a pair of hanger arms that can be engaged with the left and right grips of the bucket and that can be opened and closed in a predetermined direction, an arm elevating cylinder unit that moves the hanger arm up and down, and a hanger arm at a timing when the hanger arm is lowered to a predetermined height position. There is a bucket dispensing device provided with a roller mechanism for opening and a roller timing changing means for changing the opening / closing height position of the hanger arm by this roller mechanism.

ところで、この装置ではハンガアームを上下動させるアーム昇降シリンダユニットが段積みされた容器の上方に配設されているから、ばらし前の容器の段積み高さがハンガアームの長さ内に制限され、より多段の段積みされた容器をばらす場合はハンガアームを長く形成してアーム昇降シリンダユニットを高所に配設する必要があり、装置が大型化してしまう問題があった。また、ハンガアームが上下に往復動作して払い出すから、ハンガアームが降下する際は段ばらし作業が中断され、払い出しの速度が遅く処理能力が低いという問題もあった。
特開平１１−５９９０７号公報 By the way, in this apparatus, since the arm lifting cylinder unit for moving the hanger arm up and down is disposed above the stacked containers, the stacked height of the containers before the separation is limited within the length of the hanger arm, and more When separating multi-stage stacked containers, it is necessary to form a long hanger arm and dispose the arm elevating cylinder unit at a high place, resulting in a problem that the apparatus becomes large. In addition, since the hanger arm reciprocates up and down to dispense, there is also a problem that when the hanger arm descends, the disassembling work is interrupted, the dispensing speed is slow, and the processing capacity is low.

As the shape of the delivery section 8d, various shapes such as an S shape and a cam shape are appropriately selected according to the shape, size, and the like of the container B.

無端チェーン２の外側近接位置それぞれには、段積みされた複数段の容器Ｂの最下段を支持する支持部材１０を搬送コンベヤＣ方向へ進退可能に設けている。この支持部材１０は、その支持面が突出区間８ｃの上端に移動した時点の掛止部材６が掛止した容器Ｂの凸部Ｂａよりおよそ３ｍｍ下方に位置する高さに設けられ、その後方に配設したシリンダ１１により容器Ｂの凸部Ｂａの支持位置と凸部Ｂａと接触しない後方位置との間を進退するようにしている。１１ａはシリンダロッドである。 A support member 10 that supports the lowermost stage of a plurality of stacked containers B is provided at each outer proximity position of the endless chain 2 so as to advance and retreat in the direction of the conveyor C. The support member 10 is provided at a height that is located approximately 3 mm below the convex portion Ba of the container B on which the hook member 6 is hooked when the support surface moves to the upper end of the protruding section 8c. The disposed cylinder 11 is moved back and forth between the support position of the convex portion Ba of the container B and the rear position where it does not contact the convex portion Ba. 11a is a cylinder rod.

以下、図９〜１３に基づいて容器Ｂの段ばらしを説明する。段ばらし装置１では支持部材１０を後退させておく。容器Ｂが段ばらし装置１の下方に来ると図示しないセンサで検出し、搬送コンベヤＣを減速停止して段ばらしが開始される。段ばらし装置１は、図９（ａ）に示すように駆動スプロケット３により無端チェーン２を上向き方向に送り、掛止部材６が一定の速度で左右同期しながら駆動スプロケット３を反転して後退区間８ｅの始端に移動する。 Hereinafter, the distribution of the container B will be described with reference to FIGS. In the spreading device 1, the support member 10 is retracted. When the container B comes below the leveling device 1, it is detected by a sensor (not shown), and the conveyor C is decelerated and stopped to start leveling. As shown in FIG. 9A, the spreading device 1 feeds the endless chain 2 upward by the drive sprocket 3 and reverses the drive sprocket 3 while the latching member 6 synchronizes left and right at a constant speed. Move to the beginning of 8e.

掛止部材６は、案内ローラ６ｅがローラガイド９で拘束されて後退区間８ｅにより徐々に起き上がり、ガイドローラ６ｄがガイド溝８ａから外れてガイド板８ｂと当接して水平となった掛止受材６ａが最下段の容器Ｂの下方に来て突出区間８ｃに移行する。掛止受材６ａは図９（ｂ）に示すように無端ガイド７とガイド板８ｂで水平に保持された状態で最下段の容器Ｂの底面を下方から掛止して突出区間８ｃを上昇しながら持ち上げ、最下段から２段目の容器Ｂの凸部Ｂａが支持部材１０の上方まで移動すると、支持部材１０を支持位置まで前進させる。 The latch member 6 is a latch receiving member in which the guide roller 6e is restrained by the roller guide 9 and gradually rises by the retreating section 8e, and the guide roller 6d comes off the guide groove 8a and comes into contact with the guide plate 8b to become horizontal. 6a comes below the lowermost container B and shifts to the protruding section 8c. As shown in FIG. 9B, the latch receiving member 6a is held horizontally by the endless guide 7 and the guide plate 8b, and latches the bottom surface of the lowermost container B from below to raise the protruding section 8c. When the convex portion Ba of the container B in the second stage from the lowermost stage moves to above the support member 10, the support member 10 is advanced to the support position.

次に、図９（ｃ）に示すように駆動スプロケット３を直ちに逆転させて無端チェーン２を下向き方向に送り、最下段の容器Ｂを掛止した掛止部材６は突出区間８ｃを下方へ移動して最下段の容器Ｂを降下させるとともに、直上の２段目以降の容器Ｂが前進している支持部材１０で支持されて最下段の容器Ｂと離間し、最下段の容器Ｂは降下して搬送コンベヤＣへ移載され、掛止部材６はガイドローラ６ｄがガイド板８ｂからガイド溝８ａに嵌入することで後退して駆動スプロケット３を反転する。 Next, as shown in FIG. 9 (c), the driving sprocket 3 is immediately reversed to feed the endless chain 2 downward, and the latching member 6 that latches the lowest container B moves downward in the projecting section 8c. The lowermost container B is lowered, and the second and subsequent containers B immediately above are supported by the advancing support member 10 and are separated from the lowermost container B, and the lowermost container B is lowered. Then, the retaining member 6 moves backward by reversing the driving sprocket 3 when the guide roller 6d fits into the guide groove 8a from the guide plate 8b.

続いて、図１０（ａ）に示すように無端チェーン２の回動を維持し、従動スプロケット４を反転して受渡し区間８ｄの始端に移動した掛止部材６は、案内ローラ６ｅがローラガイド９で拘束されて図１２に示すように掛止受材６ａが矢印に沿って移行するように掛止部材６が揺動し、図１０（ｂ）に示すように容器Ｂの底面を下方からすくい上げるように掛止して残りの段積みされた容器Ｂの最下段の容器Ｂを若干持ち上げ、図１０（ｃ）に示すように最下段の容器Ｂが支持部材１０から離間する。 Subsequently, as shown in FIG. 10 (a), the guide roller 6e is a roller guide 9 in the latching member 6 that maintains the rotation of the endless chain 2 and reverses the driven sprocket 4 to move to the start end of the delivery section 8d.
