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ーアームの長さ内に制限され、より多段の段積み容器をばらす場合はハンガー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、ハンガー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 device, since the arm lifting cylinder unit for moving the hanger arm up and down is arranged above the stacking container, the stacking height of the container before unloading is limited to the length of the hanger arm, and more stages. When the stacking containers are separated, 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 a problem that when the hanger arm descends, the disposing operation is interrupted, the dispensing speed is slow, and the processing capacity is low.

また、突出区間７ａの上端から上方に従ってガイドレール７を無端チェーン２から離間して前記所定間隔離した位置になるまで湾曲させることで掛止部材６を下方向に送りながら回転させて掛止受材６ａを規制するように運動させる受渡し区間７ｂとしている。この受渡し区間７ｂの形状は、容器Ｂの形状，寸法等に応じてＳ字状，カム形状等の様々な形状が適宜選択される。また、突出区間７ａの下端から下方は、枢支具６ｂが枢支軸まわりに回転して掛止受材６ａが水平状態から下向きに傾斜して容器Ｂとは反対側へ後退させる後退区間７ｃとしている。 Further, the guide rail 7 is bent from the upper end of the projecting section 7a upward until it is separated from the endless chain 2 to the position separated by the predetermined distance, so that the latching member 6 is rotated while being fed downward to receive the latch. It is set as the delivery section 7b which moves so that the material 6a may be controlled. As the shape of the delivery section 7b, 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. Also, a downward section from the lower end of the projecting section 7a is a retreat section 7c in which the pivot support 6b rotates around the pivot shaft and the latch receiving member 6a is inclined downward from the horizontal state and retreats to the opposite side of the container B. It is said.

また、ローラ６ｄを嵌入させるローラガイド８を無端チェーン２の容器Ｂ側とその反対側それぞれに設け、容器Ｂ側のローラガイド８は、掛止部材６が掛止した容器Ｂの横振れを止めるようにし且つローラ６ｄとローラガイド８とガイドローラ６ｃとガイドレール７で掛止受材６ａの姿勢を規制して容器Ｂを掛止できるようにし、容器Ｂ側とは反対側のローラガイド８は、ガイドローラ６ｃを中心に回転して不安定となり易い掛止部材６を保持して安定的に移動できるようにしている。 Further, roller guides 8 into which the rollers 6d are fitted are provided on the container B side of the endless chain 2 and the opposite side thereof, and the roller guides 8 on the container B side stop lateral shaking of the container B on which the latching member 6 is latched. The container B can be hooked by regulating the posture of the hook receiving material 6a by the roller 6d, the roller guide 8, the guide roller 6c and the guide rail 7, and the roller guide 8 on the opposite side to the container B side is The latch member 6 that tends to become unstable by rotating around the guide roller 6c is held and can be moved stably.

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９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９は、その支持面が突出区間７ａの上端に移動した時点の掛止部材６の掛止受材６ａの掛止面よりおよそ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１０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。１０ａはシリンダロッドである。 A support member 9 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 9 is provided at a height located approximately 3 mm below the latching surface of the latch receiving member 6a of the latching member 6 at the time when the support surface moves to the upper end of the projecting section 7a. The cylinder 10 is arranged to advance and retract between the support position of the convex portion Ba of the container B and the rear position where the convex portion Ba does not contact the convex portion Ba. 10a is a cylinder rod.

以下、図８〜１１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には複数の容器Ｂが垂直方向に段積みされ、支持部材９で支持されている。図８（ａ）に示すように段ばらし装置１を作動させると、掛止部材６が無端チェーン２の回動により一定の速度で左右同期しながら従動スプロケット４を反転してガイドレール７の受渡し区間７ｂの始端に移動する。 Hereinafter, the distribution of the container B will be described with reference to FIGS. A plurality of containers B are stacked in the vertical direction in the stacking device 1 and supported by a support member 9. When the spreading device 1 is operated as shown in FIG. 8A, the guide member 7 is delivered by reversing the driven sprocket 4 while the latching member 6 is synchronized with the left and right at a constant speed by the rotation of the endless chain 2. Move to the beginning of the section 7b.

掛止部材６は、図１０に示すように掛止受材６ａの先端位置（白丸記号で示している）がＡ１，Ａ２・・・Ａｎの順に移行するように掛止部材６が揺動し、図８（ｂ）に示すように容器Ｂの凸部Ｂａを下方からすくい上げるように掛止して既段積みの最下段の容器Ｂを若干持ち上げ、図８（ｃ）に示すように最下段の容器Ｂが支持部材９から離間する。図１０において、Ｘ（黒丸記号で示している）は容器Ｂの凸部Ｂａと掛止受材６ａとの接点である。 As shown in FIG. 10, the latching member 6 swings so that the tip position (indicated by white circles) of the latching receiving member 6a shifts in the order of A1, A2,. As shown in FIG. 8 (b), the convex portion Ba of the container B is hooked so as to be scooped from below, and the lowermost container B is lifted slightly, and the lowermost stage as shown in FIG. 8 (c). The container B is separated from the support member 9. In FIG. 10, X (indicated by a black circle symbol) is a contact point between the convex portion Ba of the container B and the latch receiving member 6a.

既段積みの容器Ｂが支持部材９から離間後は、図９（ａ）に示すようにばらすべき最下段の容器Ｂを回避するように支持部材９を容器Ｂの外側へ一時的に後退させ、掛止部材６が突出区間７ａを降下して最下段の容器Ｂが支持部材９の支持高さより下方へ移動すると、図９（ｂ）に示すように支持部材９を支持位置まで前進させる。 After the already stacked container B is separated from the support member 9, the support member 9 is temporarily retracted to the outside of the container B so as to avoid the lowest container B to be separated as shown in FIG. When the latch member 6 moves down the protruding section 7a and the lowermost container B moves below the support height of the support member 9, the support member 9 is advanced to the support position as shown in FIG. 9B.

掛止部材６が最下段の容器Ｂを掛止した状態でさらに降下すると、図９（ｃ）に示すように最下段から２段目の容器Ｂが支持部材９で支持され、同２段目の容器Ｂと最下段の容器Ｂが離間する。掛止部材６は突出区間７ａの下端に来ると、最下段の容器Ｂが搬送コンベヤＣに載置されて払い出され、掛止部材６はそのまま下向きに傾斜して後退した状態で駆動スプロケット３で反転し、払い出された容器Ｂは搬送コンベヤＣで所定場所へ搬送される。以上、図８（ａ）〜（ｃ），図９（ａ）〜（ｃ）示す工程を繰り返すことで段積みされた容器Ｂを連続的にばらしながら搬送していく。 When the latching member 6 is further lowered in a state of latching the lowermost container B, the second-stage container B from the lowermost stage is supported by the support member 9 as shown in FIG. The container B and the lowermost container B are separated from each other. When the latching member 6 comes to the lower end of the projecting section 7a, the lowermost container B is placed on the conveyor C and discharged, and the latching member 6 is tilted downward and retracted as it is. The container B that has been reversed and discharged is transported to a predetermined place by the transport conveyor C. 8A to 8C and FIGS. 9A to 9C are repeated to convey the stacked containers B while continuously separating them.

支持部材９に容器が無く搬送コンベヤＣで搬送されてきた段積みされた容器Ｂをばらす場合は、図１２に示すように、搬送コンベヤＣを駆動して段積みされた容器Ｂが搬送され、同容器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を減速停止する。次に、支持部材９を後退させた状態で駆動スプロケット３を一旦逆回転させて無端チェーン２を上向き方向に送り、掛止部材６を先の軌跡とは逆に移動させて段積みされた容器Ｂを持ち上げ、最下段から２段目の容器Ｂが支持部材９で支持できる位置に来た時点で支持部材９を前進させて前記２段目の容器Ｂを支持し、直ちに駆動スプロケット３を正回転させて無端チェーン２を下向き方向に送り、掛止部材６で掛止されている最下段の容器Ｂを搬送コンベヤＣに移載する。その後無端チェーン２の下向き方向の送りを維持し、残りの容器Ｂを前記図８（ａ）〜（ｃ），図９（ａ）〜（ｃ）に示す工程を繰り返すことで連続的にばらして払い出す。 When separating the stacked containers B that have been transported by the transport conveyor C without containers in the support member 9, as shown in FIG. 12, the transported conveyor C is driven to transport the stacked containers B, 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. Next, with the support member 9 retracted, the drive sprocket 3 is once reversely rotated to feed the endless chain 2 upward, and the latching member 6 is moved in the direction opposite to the previous trajectory and stacked. B is lifted, and when the second stage container B comes to a position where it can be supported by the support member 9, the support member 9 is advanced to support the second stage container B, and the drive sprocket 3 is immediately adjusted. The endless chain 2 is rotated and sent in the downward direction, and the lowest container B that is hooked by the hooking member 6 is transferred to the conveyor C. Thereafter, the downward feed of the endless chain 2 is maintained, and the remaining container B is continuously released by repeating the steps shown in FIGS. 8 (a) to 8 (c) and FIGS. 9 (a) to 9 (c). Pay out.
