Description

本発明は、製函機によって製函され、糊付けされて偏平状に折り畳まれたダンボールケースを所定枚数ずつ一束状に積み重ねるダンボールケースの積み重ね方法とその装置に関するものである。   The present invention relates to a cardboard case stacking method and apparatus for stacking a predetermined number of corrugated cardboard boxes that have been boxed by a box making machine, glued, and folded into a flat shape.

ダンボールシートにフラップ片形成用スリットと折目を設け、糊代部分に糊付けしたのち上記折目から偏平状に折り畳んで糊代部分を接合、接着してなるダンボールケースを自動的に製造する製函機が知られているが、ダンボールケースを市場に供給する際には、糊付けされて偏平状に折り畳まれたダンボールケースを所定枚数毎に一束状に積み重ねたのち、結束機で束ねた状態にする必要がある。   A box making machine that automatically manufactures cardboard cases that have flap pieces forming slits and folds on the cardboard sheet, glued to the glue margin, folded in a flat shape from the fold, and joined and bonded together. Although the machine is known, when supplying cardboard cases to the market, the cardboard cases that have been glued and folded into a flat shape are stacked in a bundle every predetermined number of sheets, and then bundled with a binding machine. There is a need to.

このため、例えば特許文献1に記載されているように、製函機側からの折り畳まれたダンボールケースをホッパ内に上方から順次投入して積み重ね状態で収納すると共に、このホッパの下端から一枚ずつ供給コンベア上に送り出し、該供給コンベアから高速ベルト上を介してこの高速ベルトよりも搬送速度が遅い搬送コンベア上に斜め下方から送り込むことにより、該搬送コンベア上で前後に隣接するダンボールケース同士が互いにその一部を重ね合わせた斜め積み状態にする。   For this reason, as described in Patent Document 1, for example, the folded cardboard cases from the box making machine side are sequentially put into the hopper from above and stored in a stacked state, and one sheet from the lower end of the hopper The cardboard cases adjacent to each other in the front and rear on the conveyor are sent from the supply conveyor through the high-speed belt to the conveyor having a lower conveyance speed than the high-speed belt. A diagonally stacked state in which a part of each other is overlapped.

このように所定枚数、例えば、10枚のダンボールケースが搬送コンベア上に送り込まれると、上記供給コンベア及び高速ベルトを一旦停止させ、搬送コンベア上の斜め積み状態のダンボールケースを搬送終端側に配設しているストッパに順次その先端面を当接させて先に当接させたダンボールケースの下面に次のダンボールケースを潜り込ませながらストッパの垂直面に沿って上方に積み上げる。こうして所定枚数のダンボールケースが一束状に積み重ねられると、ストッパを解放させ該積載ダンボールケースを結束機側に搬出している。一方、搬送コンベア上に所定枚数のダンボールケースが斜め積み状態に供給されたのち、所定時間経過すると再び、上記供給コンベアと高速ベルトを駆動して上記同様に所定枚数のダンボールケースを搬送コンベア上に供給する。   Thus, when a predetermined number of cardboard cases, for example, 10 cardboard cases are fed onto the conveyor, the supply conveyor and the high-speed belt are temporarily stopped, and the cardboard cases in an obliquely stacked state on the conveyor are arranged on the conveyance end side. The leading end surface of the stopper is brought into contact with the stopper in turn and the next corrugated cardboard case is inserted into the lower surface of the corrugated cardboard case that has been in contact with the stopper, and the stopper is stacked upward along the vertical surface of the stopper. When a predetermined number of cardboard cases are stacked in a bundle in this way, the stopper is released and the stacked cardboard cases are carried out to the binding machine side. On the other hand, after a predetermined number of cardboard cases are obliquely stacked on the transport conveyor, when the predetermined time has elapsed, the supply conveyor and the high-speed belt are driven again so that the predetermined number of cardboard cases are placed on the transport conveyor. Supply.

また、上記偏平状に折り畳まれたダンボールケースの別な積み重ね方法として、特許文献2に記載しているように、搬送コンベアによってダンボールケースを連続的に搬送し、その搬送終端部から下方の第1ホッパ内に設けている受け部材上に所定枚数、順次投入して積載したのち、搬送コンベアの搬送終端からのダンボールケースの供給方向を切り替え手段によって搬送コンベアの延長方向に配設している中継コンベア側に切り替え、搬送コンベアからのダンボールケースをこの中継コンベア上に移載し、該中継コンベアの搬送終端部から下方の第2ホッパ内に設けている受け部材上に所定枚数、順次投入して積載する方法が開発されている。

Further, as another method of stacking the flat cardboard cases, as described in Patent Document 2, the cardboard cases are continuously transported by a transport conveyor, and a first lower portion from the transport end portion is provided. A relay conveyor in which a predetermined number of sheets are sequentially loaded and stacked on a receiving member provided in the hopper, and then the cardboard case supply direction from the transfer end of the transfer conveyor is arranged in the extension direction of the transfer conveyor by the switching means. The cardboard case from the transfer conveyor is transferred onto this relay conveyor, and a predetermined number of sheets are sequentially loaded onto the receiving member provided in the second hopper below the transfer conveyor end of the transfer conveyor and stacked. A method has been developed.
JP-A-9-328250 JP 2005-206257 A

しかしながら、前者のダンボールケースの積み重ね方法では、ホッパ内に積み重ね状態で収納されているダンボールケースをホッパの下端から供給コンベアによって一枚宛、取り出す際に、糊が未乾燥であると糊代部分の接合部にズレが生じて不良品となる虞れがあり、さらに、供給コンベアから高速ベルトを介して搬送コンベア上に所定枚数のダンボールケースの供給が行われると、供給コンベアと高速ベルトを停止させ、その間、ホッパ側からのダンボールケースの供給が行われないので、ダンボールケースの積み重ね処理能率が低下することになる。   However, in the former method of stacking cardboard cases, when the cardboard cases stored in the hopper in a stacked state are addressed to one sheet by the supply conveyor from the lower end of the hopper, if the paste is undried, If the cardboard case is supplied from the supply conveyor to the transport conveyor via the high-speed belt, the supply conveyor and the high-speed belt are stopped. In the meantime, since the cardboard case is not supplied from the hopper side, the cardboard case stacking efficiency is lowered.

また、搬送コンベアの搬送終端側で斜め積み状態のダンボールケースの先端面をストッパにより順次、受止させて積み重ねる際に、先にストッパにその先端面を当接、受止させたダンボールケースの下面に次のダンボールケースの上面を摺接させながら潜り込ませて先のダンボールケースを持ち上げながら積み上げていくものであるから、積載枚数が多くなればなる程、さらには、ダンボールケースの重なり部分が少ない程、先行するダンボールケースの下面に該ダンボールケースを持ち上げながら後続するダンボールケースを送り込ませる際に大きな摩擦力が発生してダンボールケースの送り込みが困難となるばかりでなく、ベルトが短期間で摩損する虞れがあり、また、ダンボールケース同士に引っ掛かりが生じて円滑な積み重ねができなくなるといった問題点があった。   In addition, when the front end surface of the cardboard case obliquely stacked on the transfer terminal side of the transfer conveyor is sequentially received and stacked by the stopper, the front surface of the cardboard case is first contacted and received by the stopper. Since the top of the next cardboard case is slid into contact with each other and the previous cardboard case is lifted and stacked, the larger the number of stacked cards, the fewer the overlapping parts of the cardboard cases. In addition, when the subsequent cardboard case is fed to the lower surface of the preceding cardboard case, a large frictional force is generated to make it difficult to feed the cardboard case, and the belt may be worn out in a short period of time. In addition, the cardboard cases are caught and can be stacked smoothly. There is a problem such as Kunar.

その上、積み重ねられた所定枚数のダンボールケースが搬出される間においてもストッパによる次のダンボールケースの積み重ね工程が停止することになり、処理能率が低下することになる。   In addition, the stacking process of the next cardboard case by the stopper is stopped while the predetermined number of stacked cardboard cases are carried out, and the processing efficiency is lowered.

近年、ダンボールケースの製函機の性能が一段と向上して一分間に300 〜400 枚のスピードで製函が可能となり、そのため、ダンボールケース間の搬送間隔は0.2 秒〜0.17秒となって、この極めて短時間の間に枚数のカウントや区切り等の作動を行わせる必要があるが、上記のようなダンボールケースの搬送や積み重ね工程を一旦停止する方法では、製函機による製函速度に対応させることができない。   In recent years, the performance of cardboard case box making machines has improved further, making it possible to make boxes at a speed of 300 to 400 sheets per minute. Therefore, the conveyance interval between cardboard cases has become 0.2 to 0.17 seconds. Although it is necessary to perform operations such as counting the number of sheets and separating them in a very short time, the method for temporarily stopping the cardboard case transport and stacking process as described above corresponds to the box making speed by the box making machine. I can't.

一方、後者の積み重ね方法によれば、搬送コンベアを停止させることなく、製函機から供給される折り畳まれたダンボールケースを順次、搬送コンベアによって連続的に搬送し、この搬送コンベアから第1ホッパ側の受け部材上と、中継コンべアを介して第2ホッパ側の受け部材上とに交互に一束分に相当する所定枚数のダンボールケースを積載するものであるから、上記製函機による製函速度に対応させることができなくはないが、第1、第2ホッパの一方に一束分に相当する所定枚数のダンボールケースが供給されると、上記0.2 秒〜0.17秒という極めて短い時間内に切り替え手段を作動させなければならず、この作動が可能であってもダンボールケースがこの切り替え手段の先端から離れた時から上記短時間の間に次のダンボールケースが該切り替え手段の基端部に達した状態となって、このダンボールケースを切り替えた方向に送り込むことが困難となる場合が生じる。   On the other hand, according to the latter stacking method, the folded cardboard cases supplied from the box making machine are sequentially and continuously conveyed by the conveyor without stopping the conveyor, and the first hopper side from the conveyor A predetermined number of corrugated cardboard cases corresponding to one bundle are alternately loaded on the receiving member and on the receiving member on the second hopper side via the relay conveyor. Although it is not possible to correspond to the box speed, if a predetermined number of cardboard cases corresponding to one bundle are supplied to one of the first and second hoppers, the above-mentioned 0.2 second to 0.17 second is extremely short. The switching means must be actuated at the same time, and even if this action is possible, the next cardboard case must be in a short period of time after the cardboard case is separated from the tip of the switching means. In a state of reaching the proximal end of said switching means, when it occurs that be fed in a direction switching the cardboard case becomes difficult.

さらに、搬送コンベアから切り替え手段を介して搬送コンベアの延長方向に中継コンベアを配設すると共に第1、第2ホッパやそれぞれのホッパ内に受け部材を設けているので、装置全体が大規模となって故障が発生し易くなるばかりでなく、広い設置面積を必要とし、その上、第1、第2ホッパ内の受け部材から一束分の積載ダンボールケースを順次、結束機側に搬出するための装置もそれぞれの受け部材に応じて必要とし、装置全体や動きが複雑化するといった問題点があった。   Furthermore, since the relay conveyor is arranged in the extending direction of the transport conveyor from the transport conveyor via the switching means and the receiving members are provided in the first and second hoppers and the respective hoppers, the entire apparatus becomes large-scale. In addition to being prone to failure, a large installation area is required, and in addition, a bundle of cardboard cases are sequentially transported from the receiving members in the first and second hoppers to the binding machine side. The apparatus is also required according to each receiving member, and there is a problem that the entire apparatus and the movement become complicated.

本発明はこのような問題点を全面的に解消することができるダンボールケースの積み重ね方法とその方法を実施するための装置を提供する。   The present invention provides a method for stacking cardboard cases and an apparatus for carrying out the method, which can completely eliminate such problems.

本発明のダンボールケースの積み重ね方法は、ダンボールケースの積み重ね処理が連続自動的に且つ能率よく行えるようにするため、請求項1に記載したように、偏平状に折り畳まれたダンボールケースを搬送コンベアによって順次連続的に搬送してこの搬送コンベアの搬送終端から下方のホッパ内に一枚ずつ投下することによりこのホッパの上方部内に配設した開閉自在な一次受け部材上に受止させ、複数枚のダンボールケースが該一次受け部材上に積載されると、この一次受け部材を開放して積載ダンボールケースを下方の開閉自在な二次受け部材上に落下、受止させると共に上記搬送コンベアから投下される後続のダンボールケースを開放状態を保持している一次受け部材を通過させて二次受け部材上の上記積載ダンボールケース上に積み重ね、一束分に相当するダンボールケースの積載枚数に達すると、上記一次受け部材を閉じて再びこの一次受け手段上に搬送コンベアから連続的に供給される複数枚のダンボールケースを積載状態に受止すると共に上記二次受け部材を開放して該二次受け部材上の1束分の積載ダンボールケースを下方の昇降台上に移載させたのち二次受け部材を閉止し、この二次受け部材上に次の一束分のダンボールケースが上記同様にして積み重ねられる間に、昇降台を降下させて搬出手段の搬出面上に移載したのち、元の位置まで上昇させて次の一束分のダンボールケースの受け取りに待機させることを特徴とする。   According to the cardboard case stacking method of the present invention, the cardboard case folded in a flat shape is conveyed by a transport conveyor so that the cardboard case stacking process can be performed continuously automatically and efficiently. Consecutively conveys and drops one by one into the lower hopper from the conveying end of the conveyor, thereby allowing it to be received on the openable primary receiving member disposed in the upper part of the hopper. When the cardboard case is stacked on the primary receiving member, the primary receiving member is opened, and the stacked cardboard case is dropped and received on the lower openable secondary receiving member and dropped from the conveyor. Pass the primary receiving member holding the subsequent cardboard case in an open state and place it on the stacked cardboard case on the secondary receiving member When the number of stacked cardboard cases corresponding to one bundle is reached, the primary receiving member is closed, and a plurality of cardboard cases continuously supplied from the conveyor are put on the primary receiving means again. The secondary receiving member is opened and the stacking cardboard case for one bundle on the secondary receiving member is transferred onto the lower lifting platform, and then the secondary receiving member is closed. While the next cardboard case for the next bundle is stacked on the receiving member in the same manner as described above, the lifting platform is lowered and transferred onto the carry-out surface of the carry-out means, and then raised to the original position and moved to the next one. It is characterized by having it wait for receipt of the cardboard case for a bundle.

さらに、上記ダンボールケースの積み重ね方法において、請求項2に係る発明は、一次受け部材の閉止時には搬送コンベアからのダンボールケース供給位置を高くして一次受け部材上にダンボールケースを供給し、一次受け部材の開放時には供給位置を低くすることを特徴とする。   Further, in the above method for stacking corrugated cardboard cases, the invention according to claim 2 is characterized in that when the primary receiving member is closed, the corrugated cardboard case supply position from the transport conveyor is raised to supply the corrugated cardboard case onto the primary receiving member, and the primary receiving member It is characterized in that the supply position is lowered when opening.

請求項3に係る発明は上記ダンボールケースの積み重ね方法を実施するための装置であって、偏平状に折り畳まれたダンボールケースを搬送する搬送コンベアと、この搬送コンベアの搬送終端下方のホッパ上端部内に開閉自在に配設され、閉止状態で搬送コンベアから供給されるダンボールケースを積載状態で受止すると共に複数枚のダンボールケースの積載後に開放して該積載ダンボールケースを落下させる一次受け部材と、この一次受け部材の下方に開閉自在に配設されて閉止状態で一次受け部材からの上記積載ダンボールケースを受止し且つこの積載ダンボールケース上に上記搬送コンベアからの複数枚のダンボールケースを積み重ねて一束分の枚数のダンボールケースを受止したのち開放して該一束分のダンボールケースを落下させる二次受け部材と、この二次受け部材の下方に昇降自在の配設されて該二次受け部材から一束分の積載ダンボールケースを受け取ったのち降下する昇降台と、降下した昇降台上の積載ダンボールケースの搬出手段とから構成している。   The invention according to claim 3 is an apparatus for carrying out the above-described method for stacking cardboard cases, and a transport conveyor for transporting the cardboard cases folded in a flat shape, and a hopper upper end below the transport end of the transport conveyor. A primary receiving member which is disposed so as to be openable and closable, receives a cardboard case supplied from the conveyor in a closed state in a stacked state, and opens after loading a plurality of cardboard cases to drop the stacked cardboard case; It is disposed below the primary receiving member so as to be openable and closable, receives the stacked cardboard case from the primary receiving member in a closed state, and stacks a plurality of cardboard cases from the conveyor on the stacked cardboard case. After receiving the number of cardboard cases for the bundle, the cardboard cases for the bundle are dropped and opened. A secondary receiving member, a lifting base disposed below the secondary receiving member, and descending after receiving a bundle of cardboard cases from the secondary receiving member; It is comprised from the carrying-out means of the loading cardboard case.

このように構成した装置において、請求項4に係る発明は、上記搬送コンベアの少なくとも搬送終端部側を起伏自在に構成していることを特徴とし、請求項5に係る発明は、上記搬送コンベア搬送終端部にこの搬送コンベアの上面から上方に向かって起伏自在な区分けコンベアを配設していることを特徴とする。   In the apparatus configured as described above, the invention according to claim 4 is configured such that at least the transfer terminal end side of the transfer conveyor can be raised and lowered, and the invention according to claim 5 is configured to transfer the transfer conveyor. A sorting conveyor that can be raised and lowered upward from the upper surface of the conveyor is provided at the end portion.

また、し、請求項6に係る発明は、請求項1に記載の排出手段を搬出コンベアと、昇降台からこの搬出コンベア上に移載した一束のダンボールケースを押し出す押し出し部材とから構成していることを特徴とし、請求項7に係る発明は、排出テーブルと、昇降台からこの排出テーブル上に移載した一束のダンボールケースを押し出す押し出し部材とから構成していることを特徴とする。   According to a sixth aspect of the present invention, the discharging means according to the first aspect comprises a carry-out conveyor and an extruding member that pushes out a bundle of cardboard cases transferred from the elevator to the carry-out conveyor. The invention according to claim 7 is characterized by comprising a discharge table and an extruding member for extruding a bundle of cardboard cases transferred from the lifting platform onto the discharge table.

本発明によれば、搬送コンベアによって連続的に搬送されてくるダンボールケースを搬送コンベアの搬送終端部から下方のホッパ内に落下させて該ホッパ上端部内に配設している一次受け部材上に一旦、受止させ、一束分のダンボールケースの枚数に達する前に、この一次受け部材を開放して該一次受け部材上に積載している複数枚のダンボールケースを下方の二次受け部材上に落下、受止させると共に一次受け部材の開放状態を保持させて上記搬送コンベアから投下される後続のダンボールケースをこの一次受け部材を通過させて二次受け部材上の上記積載ダンボールケース上に積み重ねるので、搬送コンベアから搬送されてくるダンボールケースを互いに摺接させることなく、従って、偏平状に折り畳まれたダンボールケースの接合部にズレを生じさせることなく、一次受け部材上から二次受け部材上に連続的に積み重ねていくことができると共に、二次受け部材上において一束分に相当する枚数のダンボールケースを確実且つ円滑に積載させることができる。   According to the present invention, the corrugated cardboard case continuously conveyed by the conveyor is dropped into the lower hopper from the conveyor terminal portion of the conveyor and temporarily placed on the primary receiving member disposed in the upper end of the hopper. Before the number of cardboard cases for one bundle is reached, the primary receiving member is opened and a plurality of cardboard cases loaded on the primary receiving member are placed on the lower secondary receiving member. The subsequent cardboard case dropped and received and held in the open state of the primary receiving member and dropped from the conveyor is passed through the primary receiving member and stacked on the stacking cardboard case on the secondary receiving member. The cardboard cases transported from the transport conveyor are not slid in contact with each other, and therefore, at the junction of the corrugated cardboard cases folded flat. The cardboard case can be stacked continuously on the secondary receiving member from the primary receiving member without causing any distortion, and the cardboard cases corresponding to one bundle can be reliably and smoothly stacked on the secondary receiving member. Can be loaded.

その上、一束分に相当するダンボールケースの積載枚数に達すると、上記一次受け部材を閉じて再びこの一次受け部材上に搬送コンベアから連続的に供給される複数枚のダンボールケースを積載状態に受止するので、この一次受け部材の下方の二次受け部材上に一束分に相当する枚数のダンボールケースが積載されているにもかかわらず、搬送コンベアからのダンボールケースの搬送を停止することなく連続的に搬送しながら、該一次受け部材上にダンボールケースを供給することができると共に、搬送コンベアからこの一次受け部材上にダンボールケースを供給している間に、二次受け部材に積載しているダンボールケースの糊の乾燥等の養生を行わせることができる。   In addition, when the number of cardboard cases corresponding to one bundle is reached, the primary receiving member is closed, and a plurality of cardboard cases continuously supplied from the conveyor are placed on the primary receiving member again. Since the cardboard case is received, the conveyance of the cardboard case from the conveyor is stopped even though the number of cardboard cases corresponding to one bundle is loaded on the secondary receiving member below the primary receiving member. The cardboard case can be supplied onto the primary receiving member while being continuously conveyed, and the cardboard case is loaded on the secondary receiving member while the cardboard case is being supplied onto the primary receiving member from the conveyor. Curing such as drying of the paste of the corrugated cardboard case can be performed.

この際、請求項2に記載したように、一次受け部材の閉止時、即ち、二次受け部材上に一束分のダンボールケースの最後のダンボールケースが投入された直後に、搬送コンベアにおけるダンボールケースの供給位置を高くするので、搬送コンベア側から一次受け部材に達するダンボールケースの供給時間を遅らせることができ、従って、この間に一次受け部材の閉止動作を確実に完了させることができてダンボールケースの高速積み重ね処理に対応させることができると共に、一次受け部材を搬送コンベアのダンボールケースの搬送終端部に突き合わせ状態に近接させ且つ該一次受け部材のダンボールケース受け面を搬送コンベアの搬送面の高さよりも一枚のダンボールケースを受け取ることができる僅かに低い位置に対向させた状態に配設して搬送コンベアから一次受け部材上に供給されるダンボールケースの滞空時間をできるだけ少なくしながら素早く供給することができ、そのため、搬送コンベアからダンボールケースを形崩れ等を生じさせることなく、殆ど搬送状態の姿勢のまま一次受け部材上に確実に供給することができる。   At this time, as described in claim 2, when the primary receiving member is closed, that is, immediately after the last corrugated cardboard case of a bundle of cardboard cases is put on the secondary receiving member, Since the feeding position of the cardboard case reaching the primary receiving member from the conveying conveyor side can be delayed, the closing operation of the primary receiving member can be reliably completed during this time, and the cardboard case It is possible to cope with high-speed stacking processing, and the primary receiving member is brought close to the end of conveyance of the cardboard case of the conveyor, and the cardboard case receiving surface of the primary receiving member is made higher than the height of the conveying surface of the conveyor. Arranged to face a slightly lower position where a single cardboard case can be received The cardboard case supplied from the transfer conveyor onto the primary receiving member can be supplied quickly while minimizing the stagnant time of the cardboard case as much as possible. The posture can be reliably supplied onto the primary receiving member.

このようなダンボールケースの供給位置を高くする手段としては、請求項4に記載したように、搬送コンベアの少なくとも搬送終端部側を起伏自在に構成しておく手段や、請求項5に記載したように、搬送コンベア搬送終端部にこの搬送コンベアの上面から上方に向かって起伏自在な区分けコンベアを配設しておく等の手段を採用することができる。   As a means for increasing the supply position of such a cardboard case, as described in claim 4, at least the conveyance terminal end side of the conveyor is configured to be undulated, or as described in claim 5. In addition, it is possible to adopt means such as disposing a sectioning conveyor that can be raised and lowered upward from the upper surface of the transfer conveyor at the transfer conveyor transfer end.

さらに、本発明によれば、一次受け部材上に複数枚のダンボールケースを積載する一方、二次受け部材を開放して該二次受け部材上の1束分の積載ダンボールケースを下方の昇降台上に移載させるので、昇降台を二次受け部材に近接させた位置で待機させておくことによって二次受け部材から一束分の積載ダンボールケースを安定した積載姿勢でもって確実且つ迅速に昇降台上に移載させることができると共に移載後に二次受け部材を素早く閉止させて、一次受け部材側からのダンボールケースの受け取りを行うことができ、従って、一次受け部材や二次受け部材及び昇降台の作動に無駄を生じさせることなく、且つ、これらの手段を配設しているホッパの空間を有効に利用して、製函機により製造されるダンボールケースを能率よく所定枚数毎に積み重ね処理することができる。   Further, according to the present invention, a plurality of cardboard cases are loaded on the primary receiving member, while the secondary receiving member is opened so that one bundle of cardboard cases on the secondary receiving member Since it is transferred to the top, the elevator board can be lifted up reliably and quickly with a stable loading posture from the secondary receiving member by holding it in a position close to the secondary receiving member. The secondary receiving member can be quickly closed after the transfer, and the cardboard case can be received from the primary receiving member side after the transfer. Therefore, the primary receiving member, the secondary receiving member and A cardboard case manufactured by a box making machine can be efficiently and efficiently used without causing waste in the operation of the lifting platform and effectively using the space of the hopper in which these means are arranged. It can be treated stacked in each.

また、二次受け部材上に次の一束分のダンボールケースが上記同様にして積み重ねられる間に、昇降台を降下させて搬出手段の搬出面上に移載するので、上記一次受け部材と二次受け部材とによってダンボールケースの積載作業を行っている間にこの搬出手段によって一束分のダンボールケースを結束機側等に円滑に送り出すことができる。このような搬出手段としては、請求項6に記載したように昇降台の降下によってこの昇降台から一束の積載ダンボールケースを受け取る搬出コンベアと、この搬出コンベア上に移載された積載のダンボールケースを押し出す押し出し部材とから構成しておくことによって、昇降台から積載ダンボールケースを該昇降台の降下によって搬出コンベア上に自動的に移載させることができると共に、押し出し部材によって積載ダンボールケースの積載歪み等を矯正しながら送り出すことができる。また、このような搬出手段としては請求項7に記載したように、搬出コンベアに代えて排出テーブルを採用し、この排出テーブル上に移載された積載ダンボールケースを押し出し部材によって適宜なコンベア上に送り出し、結束機側等に連続的に搬出するように構成しておいてもよい。   In addition, while the cardboard cases for the next bundle are stacked on the secondary receiving member in the same manner as described above, the lifting platform is lowered and transferred onto the unloading surface of the unloading means. During the loading operation of the cardboard case with the next receiving member, the cardboard case for one bundle can be smoothly sent out to the binding machine side or the like by this unloading means. As such a carrying-out means, as described in claim 6, a carry-out conveyor that receives a bundle of cardboard cases from the lift by lowering the lift, and a loaded cardboard case transferred onto the carry-out conveyor The cardboard case can be automatically transferred from the lifting platform onto the carry-out conveyor by lowering the lifting platform, and the loading distortion of the loading cardboard case can be reduced by the pushing member. It can be sent out while correcting etc. Further, as described in claim 7, as such a carrying-out means, a discharge table is adopted instead of the carry-out conveyor, and the loaded cardboard case transferred onto the discharge table is placed on an appropriate conveyor by the pushing member. You may comprise so that it may carry out continuously to sending out, the binding machine side, etc.

本発明の実施の形態を図面について説明すると、図1において、偏平状に折り畳まれたダンボールケースaの積み重ね装置は、上流側の製函機から送られてくるダンボールケースaを下流側に搬送する搬送コンベア1と、この搬送コンベア1の搬送終端から下流側の下方空間によって形成されたホッパ2と、ホッパ2の上端部内に上記搬送コンベア1の搬送終端部に対向させて開閉自在に配設されている一次受け部材3と、この一次受け部材3から下方に所定間隔存してホッパ2内に配設されている二次受け部材4と、二次受け部材4の下方空間部に昇降自在に配設されている昇降台5と、昇降台5上の積載ダンボールケースAを受け取って下流側に搬出する搬出手段6(図2に示す)とを備えてなる。   The embodiment of the present invention will be described with reference to the drawings. In FIG. 1, a stacking device for corrugated cardboard cases a folded in a flat shape transports cardboard cases a sent from an upstream box making machine to the downstream side. A conveyor 1, a hopper 2 formed by a lower space downstream from the conveyance termination of the conveyance conveyor 1, and an upper end portion of the hopper 2 are disposed so as to be openable and closable facing the conveyance termination portion of the conveyance conveyor 1. A primary receiving member 3, a secondary receiving member 4 disposed in the hopper 2 at a predetermined distance downward from the primary receiving member 3, and a lower space portion of the secondary receiving member 4 so as to freely move up and down. The elevator 5 is provided, and the unloading means 6 (shown in FIG. 2) for receiving the loaded cardboard case A on the elevator 5 and carrying it out to the downstream side.

さらに、上記搬送コンベア1の搬送終端部にこの搬送コンベア1と並列状に搬送コンベア1の上面から上方に向かって起伏自在な区分けコンベア7を配設していると共に、搬送コンベア1の搬送終端の下方と搬送終端から下流側に向かって上記ホッパ2の開口幅間隔を存した前後位置とに垂直な規制板8、9をそれぞれ配設し、これらの規制板8、9間の空間部によってダンボールケースaを受け入れ可能な上記ホッパ2を形成している。   Furthermore, a sectioning conveyor 7 that can be raised and lowered upward from the upper surface of the transport conveyor 1 is arranged in parallel with the transport conveyor 1 at the transport end portion of the transport conveyor 1, and at the end of the transport of the transport conveyor 1. The regulation plates 8 and 9 perpendicular to the lower side and the front and rear positions having the opening width interval of the hopper 2 from the conveyance end to the downstream side are respectively disposed, and the cardboard is formed by the space between these regulation plates 8 and 9. The hopper 2 that can receive the case a is formed.

上記各部の構成をさらに詳しく説明すると、搬送コンベア1は、駆動プーリと従動プーリ間に無端状に水平に掛け渡された複数本の細幅のコンベア1aを搬送方向と直交する方向に一定間隔毎に順次並設してなり、これらの全てのコンベア1aの搬送面を一定の速度でもってホッパ2側に向かって移動させるように構成していると共に、この搬送コンベア1における隣接する全てのコンベア1a、1aの搬送終端部間に搬送コンベア1と同一方向に同一速度でもって走行する上記区分けコンベア7が配設されている。この区分けコンベア7の長さは搬送コンベア1よりも短く形成されていると共に駆動プーリと従動プーリ間に無端状に掛け渡されていて基端側(上流側)のプーリを支点として先端側が上下方向に起伏回動するように構成されてあり、伏した状態においてはその搬送面を搬送コンベア1の搬送面と面一状にしている。   The configuration of each of the above parts will be described in more detail. The conveyor 1 is configured such that a plurality of narrow conveyors 1a horizontally stretched endlessly between a driving pulley and a driven pulley are arranged at regular intervals in a direction perpendicular to the conveying direction. The conveyor surfaces of all these conveyors 1a are moved toward the hopper 2 at a constant speed, and all the adjacent conveyors 1a in this conveyor 1 The sorting conveyor 7 that travels at the same speed in the same direction as the transport conveyor 1 is disposed between the transport terminal ends of 1a. The length of the sorting conveyor 7 is shorter than that of the transport conveyor 1 and is extended endlessly between the driving pulley and the driven pulley, and the leading end side is in the vertical direction with the base end (upstream side) pulley as a fulcrum. It is configured to turn up and down, and in the lying state, its transport surface is flush with the transport surface of the transport conveyor 1.

一次受け部材3は、ダンボールケースaの搬送方向に長い一定幅を有する2枚の長方形状の水平板3a、3aをダンボールケースaの搬送方向と直交する方向、即ち、搬送コンベア1の幅方向にその上面でダンボールケースaの下面一側部と他側部とをそれぞれ受止可能な一定の間隔を存して並設してなるものである。そして、このように、水平板3a、3aがダンボールケースaの下面両側部を支持可能な間隔を存している時は閉状態であり、この状態から互いに離間する方向に外側方に移動する時は開状態となる。   The primary receiving member 3 has two rectangular horizontal plates 3a, 3a having a constant width long in the conveying direction of the cardboard case a in a direction perpendicular to the conveying direction of the cardboard case a, that is, the width direction of the conveying conveyor 1. The upper surface of the corrugated cardboard case a is arranged side by side with a certain interval at which one side and the other side of the lower surface can be received. In this way, when the horizontal plates 3a, 3a are spaced apart from each other so that they can support both sides of the lower surface of the cardboard case a, they are in a closed state, and when they move outward in a direction away from this state. Is open.

さらに、一次受け部材3を構成しているこれらの水平板3a、3aは、上流側に向けているその先端を上記搬送コンベア1の搬送終端に突き合わせ状に近接させていると共に、ダンボールケースaの受け面であるこれらの水平板3a、3aの上面を搬送コンベア1の搬送面の高さよりもダンボールケースaの厚みの1〜2枚分に相当する僅かに低い高さ位置に設けて搬送コンベア1からダンボールケースaを素早く受け取ることができるように構成している。これらの水平板3a、3aの基端部側は搬送コンベア1とホッパ2の開口幅を介して対向している上記規制板9の両側部に切欠き形成した水平スリット10、10を挿通してその基端部を適宜な支持部材(図示せず)により搬送コンベア1の幅方向に開閉自在に支持されている。   Further, the horizontal plates 3a, 3a constituting the primary receiving member 3 have their leading ends directed toward the upstream side in close proximity to the conveying end of the conveying conveyor 1, and the cardboard case a The upper surfaces of these horizontal plates 3a, 3a, which are receiving surfaces, are provided at a slightly lower height corresponding to one or two sheets of the thickness of the cardboard case a than the height of the conveying surface of the conveying conveyor 1, and the conveying conveyor 1 The cardboard case a can be quickly received. These horizontal plates 3a and 3a are inserted at the base end side through horizontal slits 10 and 10 formed in notches on both sides of the regulating plate 9 facing the conveyor 1 and the opening width of the hopper 2. The base end portion is supported by an appropriate support member (not shown) so as to be opened and closed in the width direction of the conveyor 1.

また、水平板3a、3aの開閉手段としては、図示していないが流体圧シリンダを採用することができる。この場合、該流体圧シリンダのロッドを伸長させた際にロッドの先端と連結している水平板3a、3aを閉止する方向に移動させ、収縮させた時に水平板3a、3aを開放する方向に移動させるように構成すると共に、収縮動作はシリンダ内に圧力流体を供給することによって該シリンダ内に配設しているスプリングをピストンにより圧縮させながら行う一方、伸長動作は該圧力流体の圧力を開放することにより、スプリングの復元力で瞬時にロッドを伸長させることにより行うように構成している。   In addition, as a means for opening and closing the horizontal plates 3a and 3a, although not shown, a fluid pressure cylinder can be employed. In this case, when the rod of the fluid pressure cylinder is extended, the horizontal plates 3a and 3a connected to the tip of the rod are moved in the closing direction, and when contracted, the horizontal plates 3a and 3a are opened. While being configured to move, the contraction operation is performed by supplying a pressure fluid into the cylinder while the spring disposed in the cylinder is compressed by the piston, while the extension operation releases the pressure of the pressure fluid. By doing so, the rod is instantaneously extended by the restoring force of the spring.

このような開閉手段としては、上記のような流体圧シリンダ以外に適宜な機構を採用しても水平板3a、3aを迅速に閉止する方向に作動させることができ、さらに、水平板3a、3aはダンボールケースaの下面両側部を支持している閉止状態においても互いに対向する長手方向の内側端面間が離間してあり、その状態から該水平板3aの内側端面がダンボールケースaの側端面から外側に僅かに離れた位置まで移動させるだけでダンボールケースaの支持を開放し、その位置から同じ距離だけ内側方に移動させるだけでダンボールケースaの下面両側部を支持し得るので、製函機側から搬送コンベア1によってダンボールケース間の搬送間隔が0.2 秒〜0.17秒という極めて短時間であってもそれ以下の短い時間で一対の水平板3a、3aからなる一次受け部材3を瞬時に閉止させることができる。   As such an opening / closing means, it is possible to operate the horizontal plates 3a, 3a in a direction to quickly close the horizontal plates 3a, 3a even if an appropriate mechanism other than the fluid pressure cylinder as described above is adopted. Even in the closed state in which both sides of the lower surface of the cardboard case a are supported, the inner end surfaces in the longitudinal direction facing each other are separated from each other, and from this state the inner end surface of the horizontal plate 3a is separated from the side end surface of the cardboard case a. Since the support of the cardboard case a can be released simply by moving it to a position slightly away from the outside, and both sides of the lower surface of the cardboard case a can be supported by moving it inward by the same distance from that position, the box making machine The primary receiving member 3 composed of a pair of horizontal plates 3a and 3a within a very short time even if the conveyance interval between the cardboard cases is 0.2 seconds to 0.17 seconds by the conveyor 1 from the side. Can be closed instantly.

一方、上記二次受け部材4は、一次受け部材3から下方に一束の積載ダンボールケースAが収納可能な間隔を存して配設されている。この二次受け部材4は上記規制板8、9にそれぞれ複数本宛装着した流体圧シリンダ4aからなり、ホッパ2内に面している規制板8、9の対向面とは反対側に搬送コンベア1の幅方向に一定間隔毎にそれぞれ装着されていると共に、そのロッド4bを規制板8、9を貫通させてホッパ2内に出没させるように構成してあり、ホッパ2内に突出させた時に、これらのロッド4b列によって、上記一次受け部材3とは直角方向の積載ダンボールケースAの下面における前後部を受止させるようにしている。なお、下流側(前側)に配設している規制板9は、搬送コンベア1の排出端下方に固定状態で配設されている規制板8に対して接離する前後方向に移動可能にして、ホッパ2の前後方向の開口幅を調整可能としている。   On the other hand, the secondary receiving member 4 is disposed below the primary receiving member 3 with an interval in which a bundle of cardboard cases A can be stored. The secondary receiving member 4 comprises a plurality of fluid pressure cylinders 4a attached to the regulating plates 8 and 9, respectively, and is conveyed on the opposite side of the opposing surface of the regulating plates 8 and 9 facing the hopper 2. 1 is mounted at regular intervals in the width direction of 1 and the rod 4b is configured to pass through the regulating plates 8 and 9 and protrude into the hopper 2 so that the rod 4b protrudes into the hopper 2. The front and rear portions of the lower surface of the stacking cardboard case A in the direction perpendicular to the primary receiving member 3 are received by these rows of rods 4b. The regulation plate 9 disposed on the downstream side (front side) is movable in the front-rear direction so as to come in contact with and separate from the regulation plate 8 disposed in a fixed state below the discharge end of the conveyor 1. The opening width in the front-rear direction of the hopper 2 can be adjusted.

上記昇降台5は、二次受け部材4から下方の空間部内において昇降自在に配設されている。この昇降台5は、上端面が水平な端面に形成されている複数枚の垂直板5aを搬送コンベア1の幅方向に所定間隔毎に並設してなり、これらの垂直板5aを油圧シリンダ等の流体圧シリンダ(図示せず)によって同時に一体的に上下方向に昇降させるように構成している。そして、この昇降台5は、一束の積載ダンボールケースAを受止する上記水平な上端面が二次受け部材4から下方に一束の積載ダンボールケースAを設けることができる間隔を存した高さ位置に達するまで上昇し、搬出手段6の搬出面から下方に没入する位置まで降下するように構成している。   The lifting platform 5 is disposed so as to be movable up and down in the space below the secondary receiving member 4. The lifting platform 5 is formed by arranging a plurality of vertical plates 5a, the upper end surfaces of which are horizontal end surfaces, arranged in parallel in the width direction of the conveyor 1 at predetermined intervals, and these vertical plates 5a are hydraulic cylinders or the like. These fluid pressure cylinders (not shown) are configured to be moved up and down integrally at the same time. In the lifting platform 5, the horizontal upper end surface for receiving the bundle of cardboard cases A has a high interval at which the bundle of cardboard cases A can be provided below the secondary receiving member 4. It rises until it reaches the vertical position, and it is configured to descend from the carry-out surface of the carry-out means 6 to a position where it is immersed downward.

搬出手段6は、搬出コンベア6a(図2において水平な直線で示している)と上記昇降台5からこの搬出コンベア6a上に移載した一束のダンボールケースを押し出す押し出し部材6bとからなり、搬出コンベア6aはホッパ2の開口下端、即ち、前後に対向している上記規制板8、9の下端間から下方に所定間隔を存した位置に前後方向に向けて水平状に配設した細幅のコンベアであって、上記昇降台5の各隣接する垂直板5a、5a間にこれらの細幅のコンベアをそれぞれ並列状に配設してなるものである。この搬出コンベア6aの搬送始端部は搬送コンベア1の搬送終端部の下方に位置し、搬送終端部側はホッパ2の下端から下流側に延出している。   The unloading means 6 comprises an unloading conveyor 6a (shown by a horizontal straight line in FIG. 2) and an extruding member 6b for pushing out a bundle of cardboard cases transferred from the lifting platform 5 onto the unloading conveyor 6a. The conveyor 6a has a narrow width arranged horizontally in the front-rear direction at a position at a predetermined distance downward from the lower end of the opening of the hopper 2, that is, between the lower ends of the restriction plates 8, 9 facing the front and rear. It is a conveyor, and these narrow conveyors are respectively arranged in parallel between adjacent vertical plates 5a, 5a of the lifting platform 5. The transfer start end of the carry-out conveyor 6a is located below the transfer end portion of the transfer conveyor 1, and the transfer end portion side extends from the lower end of the hopper 2 to the downstream side.

また、押し出し部材6bは、その前端面をホッパ2の開口下端近傍部に達する高さを有し且つ下流側に向けた前端面を垂直な面に形成している複数枚の垂直板又は垂直枠からなり、これらの垂直板又は垂直枠の下端部を上記搬出コンベア6aと共に上記昇降台5の各隣接する垂直板5a、5a間に並列状に介在させている。そして、通常はこの押し出し部材6bを後退させてその垂直な前端面を搬送コンベア6aの搬送終端の下方から上流側に引っ込めた位置に待機させてあり、排出コンベア6a上に一束分の積載ダンボールケースAが載置された時に、ホッパ2の下方空間部に向かって移動して積載ダンボールケースAを押し出すように構成している。なお、この押し出し部材6bは油圧シリンダ等の適宜な流体圧シリンダによって作動させられる。   The push-out member 6b has a height at which the front end surface reaches the vicinity of the lower end of the opening of the hopper 2 and a plurality of vertical plates or vertical frames each having a front end surface facing the downstream side as a vertical surface. The lower ends of these vertical plates or vertical frames are interposed in parallel between the adjacent vertical plates 5a, 5a of the lifting platform 5 together with the carry-out conveyor 6a. Usually, the push-out member 6b is retracted, and the vertical front end surface is kept waiting at a position where it is retracted from the lower end to the upstream side of the transfer end of the transfer conveyor 6a. When the case A is placed, the cardboard case A is configured to move toward the lower space of the hopper 2 and push out the loaded cardboard case A. The pushing member 6b is operated by an appropriate fluid pressure cylinder such as a hydraulic cylinder.

以上のように構成したダンボールケースの積み重ね装置の作用を述べると、フラップ片形成用スリットと折目を設けたダンボールシートを製函機に供給して該折目から折り曲げられ且つ糊付けされて偏平状に折り畳まれたダンボールケースaを製造し、この製函機側から搬送コンベア1上に一定の間隔を存して順次、連続的に送り込む。製函機においては偏平状に折り畳まれたダンボールケースaは一分間に300 〜400 枚のスピードでもって製造され、従って、搬送コンベア1上にはダンボールケースaは0.2 〜0.17秒の間隔毎に規則正しく搬入され、この搬入速度に応じた走行速度でもって搬送コンベア1を下流側に向かって運行させている。   The operation of the cardboard case stacking device constructed as described above is described. The cardboard sheet provided with the flap piece forming slit and the crease is supplied to the box making machine and is folded and glued from the crease and is flat. The corrugated cardboard case “a” folded into a box is manufactured, and the cardboard case “a” is sequentially and continuously fed onto the conveyor 1 from the box making machine side at a constant interval. In the box making machine, the cardboard case a folded in a flat shape is manufactured at a speed of 300 to 400 per minute. Therefore, the cardboard case a is regularly arranged on the conveyor 1 at intervals of 0.2 to 0.17 seconds. It is carried in, and the conveyor 1 is operated toward the downstream side at a traveling speed corresponding to the carrying-in speed.

ダンボールケースの積み重ね装置は、スタート時には図2に示すように、区分けコンベア7は搬送コンベア1の搬送面に対して上方に起立していてその搬送面を下流側に向かって上方に傾斜させてあり、ダンボールケースaの一次受け部材3及び二次受け部材4は閉止状態にしてダンボールケースaの受止に待機してあり、さらに、押し出し部材6bは後退させていると共に昇降台5は上昇位置で待機している。   As shown in FIG. 2, the cardboard case stacking apparatus is such that the sorting conveyor 7 stands up with respect to the transport surface of the transport conveyor 1 and the transport surface is inclined upward toward the downstream side. The primary receiving member 3 and the secondary receiving member 4 of the cardboard case a are in the closed state and are waiting for the cardboard case a to be received. Further, the push-out member 6b is retracted and the lifting platform 5 is in the raised position. Waiting.

搬送コンベア1によって下流側に搬送されるダンボールケースaが搬送終端部に達すると、図3、図4に示すにように、上方に傾斜している区分けコンベア7の搬送面に載せられて該区分けコンベア7の上傾端からこの区分けコンベア7の搬送速度によってホッパ2の上端開口部に配設されている一次受け部材3の上方に送り出され、その先端が前方に配設している規制板9に当接してこの規制板9に沿って落下し、一次受け部材3の両側の水平板3a、3a間上に受止される。図4には1枚目のダンボールケースa-1 が一次受け部材3上に受止され、2枚目のダンボールケースa-2 が区分けコンベア7上に達している状態を示している。なお、説明上、装置やダンボールケースaの大きさ、間隔等は概略的に図示している。   When the cardboard case a transported downstream by the transport conveyor 1 reaches the transport end portion, as shown in FIGS. 3 and 4, the cardboard case a is placed on the transport surface of the section conveyor 7 inclined upward, and the section is separated. A regulating plate 9 is fed from the upper inclined end of the conveyor 7 to the upper side of the primary receiving member 3 disposed at the upper end opening of the hopper 2 by the conveying speed of the sorting conveyor 7 and the front end thereof is disposed forward. And is dropped along the regulating plate 9 and is received between the horizontal plates 3a and 3a on both sides of the primary receiving member 3. FIG. 4 shows a state in which the first cardboard case a-1 is received on the primary receiving member 3 and the second cardboard case a-2 reaches the sorting conveyor 7. For the sake of explanation, the size and interval of the device and the cardboard case a are schematically shown.

同様にしてダンボールケースaが順次、搬送コンベア1の搬送終端部から前方に向かって斜め上方に傾斜している区分けコンベア7上を通じて一次受け部材3上に順次送り込まれ、この一次受け部材3に一束分のダンボールケースの枚数の中間枚数、例えば、一束が10枚の積載ダンボールケースAからなる場合には5枚目のダンボールケースa-5 が図5に示すように供給されると、区分けコンベア7の伏動を開始させると共に一次受け部材3の水平板3a、3aを互いに離間する外側方に水平移動させて図6に示すようにダンボールケースaの支持を開放し、この一次受け部材3上に積み重ねられていた5枚のダンボールケースaを落下させて閉止中の下方の二次受け部材4の前後ロッド4b、4b列上間にそのまま受止させると共に、開放した一次受け部材3の水平板3a、3a間の空間部を通じて6枚目以降の複数枚のダンボールケースaを図7、図8に示すように二次受け部材4上の積み重ねているダンボールケース上に順次、積み重ねる。   Similarly, the cardboard cases a are sequentially fed onto the primary receiving member 3 through the sorting conveyor 7 that is inclined obliquely upward toward the front from the conveying terminal end of the conveying conveyor 1. An intermediate number of cardboard cases corresponding to a bundle, for example, if a bundle is composed of 10 stacked cardboard cases A, when the fifth cardboard case a-5 is supplied as shown in FIG. The conveyor 7 starts to bend and the horizontal plates 3a, 3a of the primary receiving member 3 are horizontally moved outwardly away from each other to release the support of the cardboard case a as shown in FIG. The five cardboard cases a stacked above are dropped and received as they are between the front and rear rods 4b and 4b of the lower secondary receiving member 4 in the closed state, and the primary receiver opened. The sixth and subsequent cardboard cases a through the space between the horizontal plates 3a and 3a of the material 3 are sequentially placed on the cardboard cases stacked on the secondary receiving member 4 as shown in FIGS. Stack up.

この際、8枚目のダンボールケースa-8 が搬送コンベア1の搬送終端部側からホッパ2の上方部側に向かって供給される時には、区分けコンベア7が完全に下方に伏してその搬送面を水平状態になってあり、従って、搬送コンベア1の搬送力によって該ダンボールケースa-8 が二次受け部材4上に供給される。   At this time, when the eighth cardboard case a-8 is supplied from the transfer terminal end side of the transfer conveyor 1 toward the upper side of the hopper 2, the sorting conveyor 7 is completely lowered and the transfer surface is lowered. Accordingly, the cardboard case a-8 is supplied onto the secondary receiving member 4 by the conveying force of the conveyor 1.

そして、10枚目のダンボールケースa-10が搬送コンベア1側からホッパ2の上端開口部に向かって供給されると、図9に示すように、区分けコンベア7が瞬時に起立してその搬送面を先端(前端)に向かって上方に傾斜した状態となり、次の11枚目のダンボールケースa-11の供給に備えると共に、上記10枚目のダンボールケースa-10が、開放している一次受け部材3の水平板3a、3a間を通じて二次受け部材4上に積み重ねている9枚目のダンボールケースa-9 上に落下、積載すると同時に上記一次受け部材3の水平板3a、3aをダンボールケースaの下面両側部を受止可能な位置まで互いに接近する方向に瞬時に移動させることにより閉止状態にする(図10、図11参照)。   Then, when the tenth cardboard case a-10 is supplied from the conveyor 1 side toward the upper end opening of the hopper 2, the sorting conveyor 7 stands up instantaneously as shown in FIG. Is inclined upward toward the tip (front end) to prepare for the supply of the next eleventh cardboard case a-11, and the tenth cardboard case a-10 is open to the primary receptacle. The horizontal plate 3a, 3a of the primary receiving member 3 is simultaneously dropped and loaded onto the ninth cardboard case a-9 stacked on the secondary receiving member 4 through the horizontal plate 3a, 3a of the member 3 A closed state is established by instantaneously moving both sides of the lower surface of a to a position where they can be received close to each other (see FIGS. 10 and 11).

なお、搬送コンベア1からホッパ2側に供給されるダンボールケースaの枚数や二次受け部材4上に積載されるダンボールケースaの枚数は適宜な検出器(図示せず)によって検出するように構成してあり、二次受け部材4上に一束分の枚数(この実施例では10枚)が積載されたのを検出すると、上記のように一次受け部材3を瞬時に閉止させると共に区分けコンベア7を起立させる。   The number of cardboard cases a supplied from the conveyor 1 to the hopper 2 side and the number of cardboard cases a stacked on the secondary receiving member 4 are detected by an appropriate detector (not shown). When it is detected that a bundle of sheets (10 sheets in this embodiment) is stacked on the secondary receiving member 4, the primary receiving member 3 is instantly closed and the sorting conveyor 7 is closed as described above. Stand up.

この場合、区分けコンベア7の起立する間に一次受け部材3を閉止させているが、区分けコンベア7が起立すると、この区分けコンベア7の搬送面が前端(先端)に向かうに従って斜め上方に傾斜しているので、上記10枚目のダンボールケースa-10に後続して搬送コンベア1により高速度で搬送されてくる11枚目のダンボールケースa-11がこの区分けコンベア7の傾斜搬送面から前方に向かって斜め上方に送り出されてホッパ2の上端開口部の上方から一次受け部材3上に緩やかな放物線を描くように供給、投下されるので、該一次受け部材3に受止されるまでの時間が、搬送コンベア1によって前方に向かって水平状に送り出されて一次受け部材3に受止されるまでの時間よりも長くなり、従って、この長くなった時間を利用して11枚目のダンボールケースa-11が一次受け部材3上に達するまでに該一次受け部材3を素早く閉止させるものである。図10は11枚目のダンボールケースa-11がこの区分けコンベア7の傾斜搬送面上に達した状態とその時の一次受け部材3の閉じ初め状態を示している。   In this case, the primary receiving member 3 is closed while the sorting conveyor 7 stands up. However, when the sorting conveyor 7 stands up, the conveying surface of the sorting conveyor 7 tilts obliquely upward toward the front end (tip). Therefore, the eleventh cardboard case a-11 conveyed at a high speed by the conveyor 1 following the tenth cardboard case a-10 is directed forward from the inclined conveyor surface of the sorting conveyor 7. Since it is fed and dropped so as to draw a gentle parabola on the primary receiving member 3 from above the upper end opening of the hopper 2, the time until it is received by the primary receiving member 3 , It takes longer than the time it is sent horizontally by the conveyor 1 until it is received by the primary receiving member 3. Rukesu a-11 is one which quickly close the primary receiving member 3 to reach on the primary receiving member 3. FIG. 10 shows a state in which the eleventh cardboard case a-11 has reached the inclined conveying surface of the sorting conveyor 7 and the initial closing state of the primary receiving member 3 at that time.

こうして、二次受け部材4上に一束の数(10枚)の積載ダンボールケースAを受止させた状態で図11から図13に示すように、一次受け部材3上に11枚目のダンボールケースa-11とこれに後続する数枚のダンボールケースa-12〜a-14を順次搬送コンベア1から区分けコンベア7上を通じて供給、積載し、15枚目のダンボールケースa-15が区分けコンベア7上に達した時に二次受け部材4の前後流体圧シリンダ4a、4a列のロッド4b、4bを収縮させて前後規制板8、9からホッパ外に没入させることにより前後ロッド4b、4b間を開いて積載ダンボールケースAの受止を解き、二次受け部材4上の一束の積載ダンボールケースAを上昇位置で待機している昇降台5上にそのまま落下、移載させる。なお、この二次受け部材4が開放するまでの間、二次受け部材4上で一束の積載ダンボールケースAが糊の乾燥等の養生時間を得るものである。   Thus, the 11th cardboard is placed on the primary receiving member 3 as shown in FIGS. 11 to 13 in a state where a bundle (ten) of the stacked cardboard cases A is received on the secondary receiving member 4. Case a-11 and several subsequent cardboard cases a-12 to a-14 are sequentially fed and stacked from the conveyor 1 onto the sorting conveyor 7, and the 15th cardboard case a-15 is fed to the sorting conveyor 7. When reaching the top, the front and rear fluid pressure cylinders 4a and 4a of the secondary receiving member 4 are contracted and the rods 4b and 4b are contracted so that the front and rear rods 4b and 4b are opened from the front and rear regulating plates 8 and 9 to the outside of the hopper. Then, the receiving of the stacked cardboard case A is released, and the bundle of stacked cardboard cases A on the secondary receiving member 4 is dropped and transferred as it is onto the lifting platform 5 waiting at the raised position. Until the secondary receiving member 4 is opened, a bundle of cardboard cases A on the secondary receiving member 4 obtains a curing time such as drying of glue.
