The storage unit 112 stores a plurality of box-making sheets S in a state of leaning against an inclined surface 111 (see FIG. 3) that intersects the horizontal direction. As shown in FIG. 3, the inclined surface 111 is a surface that is inclined with respect to the vertical plane and is arranged forward toward the upper side (a surface inclined toward the front side). The sheet surface of the box-making sheet S means the outer surface of the box-making sheet S. As shown in FIG. 1, the storage section 112 has a box-making sheet S such that the top lid side flap F1 is arranged on the right side, the side surface portion T is arranged in the center in the left-right direction, and the bottom lid side flap F2 is arranged on the left side.

As shown in FIGS. 1 and 3, the box-making sheets S are stored side by side in the rear-front direction so that the adjacent box-making sheets S overlap each other in the storage unit 112.
　なお貯留部１１２は、コンベア駆動部１１３ａにより駆動されるコンベア１１３を含むことが好ましい。コンベア１１３は、例えばベルトコンベアである。つまり、貯留部１１２では、コンベア１１３の搬送面が、立てられた状態の製函用シートＳの載置される貯留部１１２の載置面となることが好ましい。コンベア駆動部１１３ａの種類は、限定するものではないが、例えばモータである。コンベア１１３は、好ましくは、コンベア１１３上の物が前方に移動するように所定の速度で常時回転している。貯留部１１２に載置されている製函用シートＳの前方には前述の傾斜面１１１が存在し、製函用シートＳの前方への移動は傾斜面１１１により規制されるため、コンベア１１３が回転して、貯留部１１２に載置されている製函用シートＳの下部に前方へと進む搬送力が働くと、立てた状態の複数の製函用シートＳは、貯留部１１２上で（コンベア１１３上で）互いに密着する。 It is preferable that the storage unit 112 includes the conveyor 113 driven by the conveyor drive unit 113a. The conveyor 113 is, for example, a belt conveyor. That is, in the storage unit 112, it is preferable that the transport surface of the conveyor 113 is the mounting surface of the storage unit 112 on which the box-making sheet S in an upright position is placed. The type of the conveyor drive unit 113a is not limited, but is, for example, a motor. The conveyor 113 is preferably constantly rotated at a predetermined speed so that an object on the conveyor 113 moves forward. The above-mentioned inclined surface 111 exists in front of the box-making sheet S placed on the storage unit 112, and the forward movement of the box-making sheet S is restricted by the inclined surface 111, so that the conveyor 113 has a conveyor 113. When a transporting force that rotates and advances forward acts on the lower part of the box-making sheet S placed on the storage unit 112, the plurality of box-making sheets S in the upright state are placed on the storage unit 112 ( In close contact with each other (on conveyor 113).
　貯留部１１２は、貯留部ガイド１１６を含むことが好ましい。貯留部ガイド１１６は、貯留部１１２において複数の製函用シートＳが並べられる第１方向Ｄ１（本実施形態では前後方向）に直交する第２方向Ｄ２（本実施形態では左右方向）における端部に配置され、第１方向Ｄ１に延びる。貯留部ガイド１１６は、第２方向Ｄ２における一方の端部（本実施形態では左端部）に配置される。貯留部ガイド１１６は、貯留部１１２に貯留されている製函用シートＳが、第２方向Ｄ２において適切な位置に配置されるように、製函用シートＳの第２方向Ｄ２の移動を規制する。 The storage unit 112 preferably includes the storage unit guide 116. The storage unit guide 116 is an end portion in a second direction D2 (horizontal direction in the present embodiment) orthogonal to the first direction D1 (front-rear direction in the present embodiment) in which a plurality of box-making sheets S are arranged in the storage unit 112. And extends in the first direction D1. The reservoir guide 116 is arranged at one end (left end in this embodiment) in the second direction D2. The storage unit guide 116 regulates the movement of the box-making sheet S in the second direction D2 so that the box-making sheet S stored in the storage unit 112 is arranged at an appropriate position in the second direction D2. do.
　なお、貯留部ガイド１１６は、ガイド駆動部１１６ａにより第２方向Ｄ２に移動可能に構成されていることが好ましい。ガイド駆動部１１６ａは、限定するものではないが、例えばモータである。貯留部ガイド１１６の配置される位置は、使用する製函用シートＳのサイズにより変化する。具体的には、システムコントローラ５は、例えば図示しない入力部に入力される製函用シートＳのサイズの情報に基づき、ガイド駆動部１１６ａを制御して、第２方向Ｄ２における貯留部ガイド１１６の位置を調整する。なお、入力部に入力される情報は、製函用シートＳのサイズの情報に限定されるものではなく、各サイズの製函用シートＳに対する適切な貯留部ガイド１１６の位置を特定可能な情報（例えば、製函用シートＳの型番等）であればよい。 It is preferable that the storage unit guide 116 is configured to be movable in the second direction D2 by the guide drive unit 116a. The guide drive unit 116a is, but is not limited to, a motor, for example. The position where the reservoir guide 116 is arranged varies depending on the size of the box-making sheet S used. Specifically, the system controller 5 controls the guide drive unit 116a based on, for example, the size information of the box-making sheet S input to the input unit (not shown), and the storage unit guide 116 in the second direction D2. Adjust the position. The information input to the input unit is not limited to the size information of the box-making sheet S, but is information that can specify the position of the appropriate storage unit guide 116 with respect to the box-making sheet S of each size. (For example, the model number of the box-making sheet S, etc.) may be used.
　プッシャ１１４は、貯留部１１２に貯留されている複数の製函用シートＳの姿勢を保持する（製函用シートＳが後方に倒れないようにする）部材である。プッシャ１１４は、貯留部１１２に貯留されている最もシート供給装置１０の近くに配置されている製函用シートＳを押さえる。言い換えれば、プッシャ１１４は、貯留部１１２に貯留されている最後方の製函用シートＳを押さえる。 The pusher 114 is a member that holds the posture of a plurality of box-making sheets S stored in the storage unit 112 (to prevent the box-making sheet S from falling backward). The pusher 114 presses the box-making sheet S stored in the storage unit 112 closest to the sheet supply device 10. In other words, the pusher 114 presses the rearmost box-making sheet S stored in the storage unit 112.
　力付与機構１１４ａは、プッシャ１１４に前向きの力を与えて、貯留部１１２に貯留されている製函用シートＳを前方に向かって押す。 The force applying mechanism 114a applies a forward force to the pusher 114 and pushes the box-making sheet S stored in the storage unit 112 forward.
　力付与機構１１４ａの種類を限定するものではないが、本実施形態では、力付与機構１１４ａは、サーボモータである。本実施形態では、システムコントローラ５は、プッシャ１１４が製函用シートＳに加える力が所定の一定の値になるように、力付与機構１１４ａとしてのサーボモータを制御する。本実施形態のように力付与機構１１４ａとしてサーボモータを用いることで、製函用シートＳを押さえるプッシャ１１４の位置を、力付与機構１１４ａであるサーボモータからの信号に基づいて検知できる。言い換えれば、本実施形態の力付与機構１１４ａは、プッシャ位置検知部の一例である。製函用シートＳを押さえるプッシャ１１４の位置を検知することで、プッシャ１１４により押される最後方の製函用シートＳの位置を検知できる。 The type of the force applying mechanism 114a is not limited, but in the present embodiment, the force applying mechanism 114a is a servomotor. In the present embodiment, the system controller 5 controls the servomotor as the force applying mechanism 114a so that the force applied to the box-making sheet S by the pusher 114 becomes a predetermined constant value. By using the servomotor as the force applying mechanism 114a as in the present embodiment, the position of the pusher 114 that presses the box-making sheet S can be detected based on the signal from the servomotor that is the force applying mechanism 114a. In other words, the force applying mechanism 114a of the present embodiment is an example of the pusher position detecting unit. By detecting the position of the pusher 114 that presses the box-making sheet S, the position of the rearmost box-making sheet S pushed by the pusher 114 can be detected.
　プッシャ１１４の位置の情報は、例えば、貯留部１１２に貯留されている製函用シートＳの貯留量の検知等に利用することができる。例えば、システムコントローラ５は、検知された製函用シートＳの貯留量の情報に基づいて、シート供給装置１０のコントローラ９０に、製函用シートＳの供給要求信号や、製函用シートＳの供給禁止信号を送信してもよい。 The information on the position of the pusher 114 can be used, for example, to detect the stored amount of the box-making sheet S stored in the storage unit 112. For example, the system controller 5 informs the controller 90 of the sheet supply device 10 of the supply request signal of the box-making sheet S and the box-making sheet S based on the detected information on the stored amount of the box-making sheet S. A supply prohibition signal may be transmitted.
　なお、力付与機構１１４ａを用いてプッシャ位置を検知しない場合、力付与機構１１４ａは、例えば、バネ等の弾性体等であってもよい。 When the pusher position is not detected by using the force applying mechanism 114a, the force applying mechanism 114a may be, for example, an elastic body such as a spring.
　なお、力付与機構１１４ａをプッシャ１１４の位置で検知しない場合、プッシャ１１４の位置や、プッシャ１１４により押される最後方の製函用シートＳの位置は、例えば光電センサなど、他の種類のセンサを用いて検知されてもよい。 When the force applying mechanism 114a is not detected at the position of the pusher 114, the position of the pusher 114 or the position of the rearmost box-making sheet S pushed by the pusher 114 may be a sensor of another type such as a photoelectric sensor. It may be detected by using.
　プッシャ切換部１１４ｂは、プッシャ１１４を、製函用シートＳを押さえる当接位置と、製函用シートＳに当接しない退避位置と、の間で移動させる駆動部である。プッシャ切換部１１４ｂの種類を限定するものではないが、本実施形態では、プッシャ切換部１１４ｂはエアシリンダである。本実施形態では、プッシャ切換部１１４ｂは、プッシャ１１４を左右方向に移動させて、プッシャ１１４を、製函用シートＳを押さえる当接位置（図６Ｂ参照）と、製函用シートＳに当接しない退避位置（図６Ｃ参照）と、の間で移動させる。 The pusher switching unit 114b is a drive unit that moves the pusher 114 between a contact position that presses the box-making sheet S and a retracted position that does not contact the box-making sheet S. Although the type of the pusher switching unit 114b is not limited, in the present embodiment, the pusher switching unit 114b is an air cylinder. In the present embodiment, the pusher switching unit 114b moves the pusher 114 in the left-right direction to bring the pusher 114 into contact with the contact position (see FIG. 6B) for holding the box-making sheet S and the box-making sheet S. Do not move between the retracted position (see FIG. 6C).
　シート供給装置１０が製函装置１００の貯留部１１２に製函用シートＳを供給する際、プッシャ１１４が当接位置に配置されていると、製函用シートＳの供給が妨げられる。そのため、システムコントローラ５は、シート供給装置１０のコントローラ９０から製函用シートＳを供給する旨の信号が入力されると、プッシャ切換部１１４ｂを制御して、プッシャ１１４を退避位置へと移動させる。 When the sheet supply device 10 supplies the box-making sheet S to the storage unit 112 of the box-making device 100, if the pusher 114 is arranged at the contact position, the supply of the box-making sheet S is hindered. Therefore, when a signal to supply the box-making sheet S is input from the controller 90 of the sheet supply device 10, the system controller 5 controls the pusher switching unit 114b to move the pusher 114 to the retracted position. ..
　シート移動部１１８は、貯留部１１２に貯留されている製函用シートＳを取り出して、製函機構１２０に供給する。例えば、シート移動部１１８は、図示しない吸盤で貯留部１１２に貯留されている製函用シートＳを吸着し、その状態で吸盤を移動させることで、製函用シートＳを製函機構１２０に供給する。具体的には、シート移動部１１８は、貯留部１１２に配置されている製函用シートＳのうち、最前方の製函用シートＳを保持し、上部前方に位置する製函機構１２０へと搬送する。 The sheet moving unit 118 takes out the box-making sheet S stored in the storage unit 112 and supplies it to the box-making mechanism 120. For example, the sheet moving unit 118 sucks the box-making sheet S stored in the storage unit 112 with a suction cup (not shown), and moves the suction cup in that state to transfer the box-making sheet S to the box-making mechanism 120. Supply. Specifically, the sheet moving unit 118 holds the frontmost box-making sheet S among the box-making sheets S arranged in the storage unit 112, and moves to the box-making mechanism 120 located in front of the upper part. Transport.

The suction drive unit 136 is, but is not limited to, a vacuum pump, for example. The first drive unit 137 and the second drive unit 138 are, but are not limited to, an air cylinder, for example. The operations of the suction drive unit 136, the first drive unit 137, and the second drive unit 138 are controlled by the system controller 5.
　図５のように、複数の第１吸盤１３１の少なくとも１つはシート移動部１１８が供給する製函用シートＳの側面Ｔ１を吸引し、複数の第１吸盤１３１の少なくとも１つはシート移動部１１８が供給する製函用シートＳの側面Ｔ２を吸引する。複数の第２吸盤１３２は、所定のタイミングで製函用シートＳの側面Ｔ３を吸引する。複数の第３吸盤１３３は、所定のタイミングで製函用シートＳの側面Ｔ４を吸引する。 As shown in FIG. 5, at least one of the plurality of first suction cups 131 sucks the side surface T1 of the box-making sheet S supplied by the sheet moving portion 118, and at least one of the plurality of first suction cups 131 is the seat moving portion. The side surface T2 of the box-making sheet S supplied by 118 is sucked. The plurality of second suction cups 132 suck the side surface T3 of the box-making sheet S at a predetermined timing. The plurality of third suction cups 133 suck the side surface T4 of the box-making sheet S at a predetermined timing.
　第１支持部１３４は、複数の第２吸盤１３２を支持する（図５参照）。また、第１支持部１３４の先端部は、複数の第３吸盤１３３が設けられた第２支持部１３５を支持している（図５参照）。第１支持部１３４は、第１駆動部１３７により駆動されて、前後方向に延びる回転軸１３４ａ周りを回転可能に構成されている。 The first support portion 134 supports a plurality of second suction cups 132 (see FIG. 5). Further, the tip portion of the first support portion 134 supports the second support portion 135 provided with a plurality of third suction cups 133 (see FIG. 5). The first support portion 134 is driven by the first drive portion 137 and is configured to be rotatable around a rotation shaft 134a extending in the front-rear direction.
　開函部１３０が製函用シートＳを開く際、複数の第１吸盤１３１は、シート移動部１１８により供給される製函用シートＳの、後方側に配置される製函用シートＳの側面Ｔ１及び側面Ｔ２に吸い付き、側面Ｔ１及び側面Ｔ２を把持する（図５参照）。また、開函部１３０が製函用シートＳを開く際には、第１支持部１３４は、複数の第２吸盤１３２が、シート移動部１１８により供給される製函用シートＳの前方側に配置されるＴ３に接触するよう、第１駆動部１３７により移動させられる。そして、複数の第２吸盤１３２は、側面Ｔ３に吸い付き、側面Ｔ３を把持する。この状態で、第１支持部１３４が第１駆動部１３７により駆動されて図５における時計方向に回転し、第１吸盤１３１が適切なタイミングで側面Ｔ１及び側面Ｔ２の把持をやめることで、所定の位置において、製函用シートＳが開かれた状態（筒状のダンボール箱Ｂ）となる。 When the box-opening portion 130 opens the box-making sheet S, the plurality of first suction cups 131 are the side surfaces of the box-making sheet S arranged on the rear side of the box-making sheet S supplied by the sheet moving portion 118. It sticks to T1 and the side surface T2 and grips the side surface T1 and the side surface T2 (see FIG. 5).

It is moved by the first drive unit 137 so as to come into contact with the T3 to be arranged. Then, the plurality of second suction cups 132 attract to the side surface T3 and grip the side surface T3. In this state, the first support unit 134 is driven by the first drive unit 137 to rotate clockwise in FIG. 5, and the first suction cup 131 stops gripping the side surface T1 and the side surface T2 at an appropriate timing. At the position of, the box-making sheet S is opened (cylindrical cardboard box B).
　このようにして開かれた製函用シートＳ（筒状のダンボール箱Ｂ）は、第２吸盤１３２により側面Ｔ３が把持される。また、製函用シートＳが開かれる際に、複数の第３吸盤１３３が側面Ｔ４に接触するように、第２支持部１３５が第２駆動部１３８により回動させられ、複数の第３吸盤１３３が、側面Ｔ４を吸引してこれを把持する（図５参照）。 The side surface T3 of the box-making sheet S (cylindrical cardboard box B) opened in this way is gripped by the second suction cup 132. Further, when the box-making sheet S is opened, the second support portion 135 is rotated by the second drive unit 138 so that the plurality of third suction cups 133 come into contact with the side surface T4, and the plurality of third suction cups 133 sucks the side surface T4 and grips it (see FIG. 5).
　開函部１３０は、第２吸盤１３２により側面Ｔ３を把持し、第３吸盤１３３により側面Ｔ４を把持することで、所定の位置でダンボール箱Ｂ（開いた製函用シートＳ）を支持する。底蓋形成部１５０は、開函部１３０により所定の位置で支持されるダンボール箱Ｂの底蓋ＢＣ側のフラップＦ２を折り込んで、ダンボール箱Ｂの底蓋ＢＣ側の開口を閉じる。底蓋形成部１５０は、第２吸盤１３２により側面Ｔ３が把持され、第３吸盤１３３により側面Ｔ３が把持している状態で、開函部１３０が開函した製函用シートＳの底蓋側フラップＦ２を閉じて底蓋ＢＣを形成する。 The box opening portion 130 supports the cardboard box B (open box making sheet S) at a predetermined position by gripping the side surface T3 by the second suction cup 132 and the side surface T4 by the third suction cup 133. The bottom lid forming portion 150 folds the flap F2 on the bottom lid BC side of the cardboard box B supported at a predetermined position by the box opening portion 130, and closes the opening on the bottom lid BC side of the cardboard box B. In the bottom lid forming portion 150, the bottom lid side of the box-making sheet S opened by the box-opening portion 130 while the side surface T3 is gripped by the second suction cup 132 and the side surface T3 is gripped by the third suction cup 133. The flap F2 is closed to form the bottom lid BC.
　（３－２－２）底蓋形成部
　底蓋形成部１５０は、開函部１３０の第２吸盤１３２及び第３吸盤１３３が支持している状態で、開函部１３０が開函したダンボール箱Ｂの底蓋側フラップＦ２を閉じて、底蓋ＢＣを形成する。なお、図示の都合上、図３では、開函部１３０の位置と底蓋形成部１５０の位置とを別の位置に描画している。 (3-2-2) Bottom lid forming portion The bottom lid forming portion 150 is a cardboard box in which the opening portion 130 is opened while the second suction cup 132 and the third suction cup 133 of the opening portion 130 support the bottom lid forming portion. The bottom lid side flap F2 of B is closed to form the bottom lid BC. For convenience of illustration, in FIG. 3, the position of the box opening portion 130 and the position of the bottom lid forming portion 150 are drawn at different positions.
　底蓋形成部１５０は、底蓋側フラップＦ２に接触して底蓋側フラップＦ２を閉じる閉鎖部材１５２と、閉鎖部材１５２を駆動する駆動部１５２ａと、を含む。駆動部１５２ａは、限定するものではないが、例えばエアシリンダである。駆動部１５２ａの動作は、システムコントローラ５により制御される。 The bottom lid forming portion 150 includes a closing member 152 that contacts the bottom lid side flap F2 and closes the bottom lid side flap F2, and a driving portion 152a that drives the closing member 152. The drive unit 152a is, but is not limited to, an air cylinder, for example. The operation of the drive unit 152a is controlled by the system controller 5.
　底蓋形成部１５０は、駆動部１５２ａにより閉鎖部材１５２を駆動して、開函部１３０が開函した製函用シートＳの底蓋側フラップＦ２に閉鎖部材１５２を接触させて底蓋側フラップＦ２を閉める。言い換えれば、底蓋形成部１５０は、開函部１３０により開函された製函用シートＳの底蓋側フラップＦ２を閉じて底蓋ＢＣを形成し、底蓋ＢＣを有するダンボール箱Ｂを製函する。具体的には、底蓋形成部１５０は、閉鎖部材１５２で、各底蓋側フラップＦ２の外面に、その底蓋側フラップＦ２に隣接する一方の底蓋側フラップＦ２の一部分が重なるように底蓋側フラップＦ２を折り込み、底蓋ＢＣを形成する。言い換えれば、底蓋形成部１５０は、底蓋側フラップＦ２をいわゆる卍折りする。なお、上記の底蓋ＢＣの形成方法は一例にすぎず、例えば底蓋側フラップＦ２にテープを貼り付けて底蓋ＢＣが形成されてもよい。底蓋ＢＣの形成方法に応じ、種々の封函機構が適宜利用されればよい。 The bottom lid forming portion 150 drives the closing member 152 by the driving portion 152a, and brings the closing member 152 into contact with the bottom lid side flap F2 of the box making sheet S opened by the box opening portion 130 to bring the closing member 152 into contact with the bottom lid side flap. Close F2. In other words, the bottom lid forming portion 150 closes the bottom lid side flap F2 of the box making sheet S opened by the box opening portion 130 to form the bottom lid BC, and manufactures a cardboard box B having the bottom lid BC. Box. Specifically, the bottom lid forming portion 150 is a closing member 152, and the bottom thereof is such that a part of one bottom lid side flap F2 adjacent to the bottom lid side flap F2 overlaps the outer surface of each bottom lid side flap F2. The lid side flap F2 is folded to form the bottom lid BC. In other words, the bottom lid forming portion 150 folds the bottom lid side flap F2 so-called swastika. The method for forming the bottom lid BC is only an example, and for example, a tape may be attached to the bottom lid side flap F2 to form the bottom lid BC. Various sealing mechanisms may be appropriately used depending on the method of forming the bottom lid BC.
　底蓋形成部１５０が底蓋ＢＣを形成したダンボール箱Ｂは、箱供給装置２により箱詰装置３の箱詰位置へと搬送される。 The cardboard box B in which the bottom lid forming portion 150 forms the bottom lid BC is conveyed to the boxing position of the boxing device 3 by the box supply device 2.
　（４）シート供給装置
　シート供給装置１０の各構成について、図１～図４に加え、図６Ａ～図６Ｆ、図６Ａ～図６Ｆを参照しながら説明する。図６Ａ～図６Ｆは、シート供給装置１０の概略斜視図であり、運転中のシート供給装置１０の動作状態の変化を描画している。図７Ａ～図７Ｆは、シート供給装置１０の概略左側面図であり、運転中のシート供給装置１０の動作状態の変化を描画している。 (4) Sheet Supply Device Each configuration of the sheet supply device 10 will be described with reference to FIGS. 6A to 6F and FIGS. 6A to 6F in addition to FIGS. 1 to 4. 6A to 6F are schematic perspective views of the seat supply device 10, and depicts changes in the operating state of the seat supply device 10 during operation. 7A to 7F are schematic left side views of the seat supply device 10, and depict changes in the operating state of the seat supply device 10 during operation.
　（４－１）載置部及び供給部
　載置部２０は、外部から供給される、シート面が水平方向に沿うように寝かされている状態の複数の製函用シートＳを受け取る部材である。載置部２０には、外部から製函用シートＳが供給される方向に沿って、回転自在なフリーローラ２１が複数並べて配置されている（図１参照）。 (4-1) Mounting section and supply section The mounting section 20 is a member that receives a plurality of box-making sheets S supplied from the outside in a state where the sheet surface is laid down along the horizontal direction. be. A plurality of rotatable free rollers 21 are arranged side by side in the mounting portion 20 along the direction in which the box-making sheet S is supplied from the outside (see FIG. 1).
　載置部２０は、その姿勢を、供給部６０の第１駆動部６２により、３つの姿勢（第１姿勢Ｐ１、第２姿勢Ｐ２、及び第３姿勢Ｐ３）の間で変更可能である。第１駆動部６２は、限定するものではないが、例えばモータやエアシリンダである。第１駆動部６２は、単一のモータやエアシリンダでもよいし、複数のモータやエアシリンダを有してもよい。 The posture of the mounting unit 20 can be changed between three postures (first posture P1, second posture P2, and third posture P3) by the first drive unit 62 of the supply unit 60. The first drive unit 62 is, but is not limited to, a motor or an air cylinder, for example. The first drive unit 62 may have a single motor or an air cylinder, or may have a plurality of motors or air cylinders.
　製函用シートＳは、載置部２０の姿勢が第１姿勢Ｐ１である時に外部から供給される。言い換えれば、第１姿勢Ｐ１は、載置部２０が、複数の製函用シートＳを外部から受け取る際の姿勢である。第１姿勢Ｐ１は、製函用シートＳが載置される載置面２０ｓ（言い換えればフリーローラ２１の搬送面）が概ね水平面となる姿勢である。なお、載置面２０ｓは、載置部２０が第１姿勢Ｐ１を取る時に製函用シートＳが載置される載置部２０の上面である。第１姿勢Ｐ１の載置部２０において、複数のフリーローラ２１は、前後方向に沿って並べて配置されている。製函用シートＳは、外部から、載置部２０の後方側から前方に向かって供給される。 The box-making sheet S is supplied from the outside when the posture of the mounting portion 20 is the first posture P1. In other words, the first posture P1 is a posture when the mounting portion 20 receives a plurality of box-making sheets S from the outside. The first posture P1 is a posture in which the mounting surface 20s (in other words, the transport surface of the free roller 21) on which the box-making sheet S is mounted is substantially horizontal. The mounting surface 20s is the upper surface of the mounting portion 20 on which the box-making sheet S is mounted when the mounting portion 20 takes the first posture P1. In the mounting portion 20 of the first posture P1, the plurality of free rollers 21 are arranged side by side along the front-rear direction. The box-making sheet S is supplied from the outside from the rear side of the mounting portion 20 toward the front.
　第２姿勢Ｐ２は、第１姿勢Ｐ１における載置部２０の後方端（第１端２２）が、第１姿勢Ｐ１における載置部２０の前方端（第２端２４）の直上付近に配置される状態である（図７Ａ及び図７Ｄ参照）。第２姿勢Ｐ２の載置部２０の載置面２０ｓ（フリーローラ２１の搬送面）は、概ね鉛直面となる。より具体的には、第２姿勢Ｐ２の載置部２０の載置面２０ｓは、貯留部１１２の製函用シートＳが立て掛けられる傾斜面１１１と概ね平行になる（図１２Ｄ参照）。言い換えれば、第２姿勢Ｐ２を取る時に、載置部２０の第１端２２は第２端２４より前方に配置され、載置部２０の載置面２０ｓは、鉛直面に対し前方側に傾いている。 In the second posture P2, the rear end (first end 22) of the mounting portion 20 in the first posture P1 is arranged in the vicinity immediately above the front end (second end 24) of the mounting portion 20 in the first posture P1. (See FIGS. 7A and 7D). The mounting surface 20s (conveying surface of the free roller 21) of the mounting portion 20 of the second posture P2 is substantially vertically facing. More specifically, the mounting surface 20s of the mounting portion 20 of the second posture P2 is substantially parallel to the inclined surface 111 on which the box-making sheet S of the storage portion 112 is leaned (see FIG. 12D). In other words, when the second posture P2 is taken, the first end 22 of the mounting portion 20 is arranged in front of the second end 24, and the mounting surface 20s of the mounting portion 20 is tilted forward with respect to the vertical plane. ing.
　供給部６０は、載置部２０の載置面２０ｓに複数の製函用シートＳが載置された後に、第１駆動部６２により載置部２０の姿勢を、第１姿勢Ｐ１から、第２姿勢Ｐ２まで変化させる。その結果、載置部２０上の複数の製函用シートＳが、シート面が水平方向に沿うように寝かされている状態から、シート面が水平方向に対して交差するように立てた状態に姿勢変更され、姿勢変更された複数の製函用シートＳは、製函装置１００の貯留部１１２に供給される。 After the plurality of box-making sheets S are mounted on the mounting surface 20s of the mounting section 20, the supply section 60 changes the posture of the mounting section 20 from the first posture P1 by the first drive section 62. 2 Change to posture P2. As a result, a plurality of box-making sheets S on the mounting portion 20 are erected so that the sheet surfaces intersect with each other from the state in which the sheet surfaces are laid down along the horizontal direction. The plurality of box-making sheets S whose postures have been changed to the above are supplied to the storage unit 112 of the box-making device 100.
　なお、ここでは、第１駆動部６２は、回転軸６６周りに載置部２０を回転させることで、載置部２０の姿勢を第１姿勢Ｐ１から第２姿勢Ｐ２に変更する。回転軸６６は、載置部２０の第２端２４側の端部に配置される回転軸である。言い換えれば、回転軸６６は、載置部２０が第１姿勢Ｐ１にある時に、載置部２０の、製函装置１００の貯留部１１２の近位側の端部に配置される。 Here, the first drive unit 62 changes the posture of the mounting unit 20 from the first posture P1 to the second posture P2 by rotating the mounting unit 20 around the rotation shaft 66. The rotation shaft 66 is a rotation shaft arranged at the end of the mounting portion 20 on the second end 24 side. In other words, the rotating shaft 66 is arranged at the proximal end of the mounting section 20 of the storage section 112 of the box making device 100 when the mounting section 20 is in the first posture P1.
　第３姿勢Ｐ３は、載置部２０を第１姿勢Ｐ１から第２姿勢Ｐ２へと変化させる途中の姿勢である。第３姿勢Ｐ３は、載置部２０の第１端２２が、載置部２０の第２端２４より上方に配置され、載置部２０の載置面２０ｓ（フリーローラ２１の搬送面）が前方に向かって下り勾配となる姿勢である（図７Ｂ参照）。例えば、数値範囲を限定するものではないが、第３姿勢Ｐ３の載置部２０の水平面に対する傾きαは、５°以上３０°以下の範囲である。言い換えれば、第１駆動部６２は、第１姿勢Ｐ１の載置部２０を回転軸６６周りに、９０°より小さなα度だけ回転させることで、載置部２０の姿勢を第３姿勢Ｐ３へと変化させる。 The third posture P3 is a posture in which the mounting portion 20 is being changed from the first posture P1 to the second posture P2. In the third posture P3, the first end 22 of the mounting portion 20 is arranged above the second end 24 of the mounting portion 20, and the mounting surface 20s (transport surface of the free roller 21) of the mounting portion 20 is arranged. The posture is a downward slope toward the front (see FIG. 7B). For example, although the numerical range is not limited, the inclination α of the mounting portion 20 of the third posture P3 with respect to the horizontal plane is in the range of 5 ° or more and 30 ° or less. In other words, the first drive unit 62 rotates the mounting portion 20 of the first posture P1 around the rotation axis 66 by an α degree smaller than 90 ° to change the posture of the mounting portion 20 to the third posture P3. To change.
　なお、載置部２０は、第１駆動部６２により姿勢が変更されるのに加え、前後方向に移動可能であることが好ましい。言い換えれば、供給部６０は、載置部２０を前後方向に移動させずにその場で姿勢変更だけをさせるのではなく、載置部２０を前後方向に移動させた上で、載置部２０の姿勢変更が可能であるように構成されることが好ましい。このように構成されることで、シート供給装置１０により貯留部１１２の適切な位置に製函用シートＳを供給することができる。 It is preferable that the mounting unit 20 can move in the front-rear direction in addition to being changed in posture by the first drive unit 62. In other words, the supply unit 60 does not only change the posture on the spot without moving the mounting unit 20 in the front-rear direction, but moves the mounting unit 20 in the front-rear direction and then mounts the mounting unit 20. It is preferable that it is configured so that the posture of the can be changed. With this configuration, the box-making sheet S can be supplied to an appropriate position of the storage unit 112 by the sheet supply device 10.
　載置部２０は、例えば、図示しないガイドレールに沿って前後に移動可能である。載置部２０を前後に移動させるため、供給部６０は、第１駆動部６２に加え、載置部２０を前後に移動させる第２駆動部６４を備える。限定するものではないが、第２駆動部６４は、例えばサーボモータである。そして、供給部６０は、第１駆動部６２により載置部２０の姿勢を第２姿勢Ｐ２に変更する前に、第２駆動部６４により載置部２０を製函装置１００の貯留部１１２に接近する第１移動方向Ｍ１に移動させる。ここでは、第１移動方向Ｍ１は前方である。なお、第２駆動部６４が載置部２０を移動させる位置（第１駆動部６２が載置部２０の姿勢を第２姿勢Ｐ２にまで変更する位置、以下では第２姿勢変更位置とも呼ぶ）は常に同じでもよい。第２姿勢変更位置を常に同じ位置にする場合、第２姿勢変更位置は、例えば、載置部２０の姿勢変更時に載置部２０や後述するストッパ３０が貯留部１１２に既に載置されている製函用シートＳに接触しない範囲で、かつ、製函装置１００の傾斜面１１１とは離れ過ぎない範囲で適宜決定されればよい。第２姿勢変更位置が、製函装置１００の傾斜面１１１と離れ過ぎているとは、例えば、貯留部１１２に製函用シートＳが無い時に、シート供給装置１０が供給する製函用シートＳが前方に倒れた場合に、倒れた製函用シートＳの前方側のシート面が傾斜面１１１に当たり得ない位置を意味する。 The mounting portion 20 can be moved back and forth along a guide rail (not shown), for example. In order to move the mounting unit 20 back and forth, the supply unit 60 includes a second driving unit 64 that moves the mounting unit 20 back and forth in addition to the first driving unit 62. Although not limited, the second drive unit 64 is, for example, a servomotor. Then, before the posture of the mounting unit 20 is changed to the second posture P2 by the first driving unit 62, the supply unit 60 transfers the mounting unit 20 to the storage unit 112 of the box making device 100 by the second driving unit 64. It is moved in the approaching first movement direction M1. Here, the first movement direction M1 is forward. The position where the second drive unit 64 moves the mounting unit 20 (the position where the first drive unit 62 changes the posture of the mounting unit 20 to the second posture P2, hereinafter also referred to as the second posture change position). May always be the same. When the second posture change position is always the same, for example, when the posture of the mounting portion 20 is changed, the mounting portion 20 and the stopper 30 described later are already mounted on the storage portion 112. It may be appropriately determined within a range not in contact with the box-making sheet S and within a range not too far from the inclined surface 111 of the box-making device 100. The fact that the second posture change position is too far from the inclined surface 111 of the box making device 100 means that, for example, the box making sheet S supplied by the sheet supply device 10 when the storage unit 112 does not have the box making sheet S. Means a position where the seat surface on the front side of the collapsed box-making sheet S cannot hit the inclined surface 111 when the vehicle is tilted forward.
　ただし、第２姿勢変更位置は、好ましくは、後述する判断部９４の判断結果に基づき決定されることが好ましい。判断部９４の判断結果に基づく第２姿勢変更位置の決定に関しては後述する。 However, it is preferable that the second posture change position is determined based on the determination result of the determination unit 94, which will be described later. The determination of the second posture change position based on the determination result of the determination unit 94 will be described later.
　載置部２０は、好ましくは、ストッパ３０と、切換部の一例としてのストッパ駆動部３２と、を有する。 The mounting unit 20 preferably has a stopper 30 and a stopper drive unit 32 as an example of the switching unit.
　ストッパ３０は、載置部２０の、製函装置１００の貯留部１１２の近位側の端部に配置される部材である。言い換えれば、ストッパ３０は、載置部２０の第２端２４側の端部に配置される部材である。 The stopper 30 is a member arranged at the proximal end of the storage portion 112 of the box making device 100 of the mounting portion 20. In other words, the stopper 30 is a member arranged at the end of the mounting portion 20 on the second end 24 side.
　ストッパ駆動部３２は、ストッパ３０の状態を、第１状態Ｃ１（図７Ｄ参照）と、第２状態（図７Ｅ参照）と、の間で切り換える駆動部である。ストッパ駆動部３２は、限定するものではないが、例えばモータやエアシリンダである。第１状態Ｃ１は、ストッパ３０が、載置部２０の載置面２０ｓから製函用シートＳの載置される側に突出する状態である。第２状態Ｃ２は、ストッパ３０が、載置部２０の載置面２０ｓから製函用シートＳの載置される側に突出しない状態である。ストッパ３０が第１状態Ｃ１にある場合には、載置部２０の載置面２０ｓに製函用シートＳが載置されている製函用シートＳの端部がストッパ３０に接触する可能性がある。特に、ストッパ３０が第１状態Ｃ１にある状態で、載置部２０の姿勢が第１姿勢Ｐ１から前方に傾斜する姿勢に変更されると、ストッパ３０が、載置部２０の載置面２０ｓに載置されている製函用シートＳを下方から支持する。一方、ストッパ３０が第２状態Ｃ２にある場合には、載置部２０の載置面２０ｓに製函用シートＳが載置されていても、製函用シートＳはストッパ３０に接触しない。 The stopper drive unit 32 is a drive unit that switches the state of the stopper 30 between the first state C1 (see FIG. 7D) and the second state (see FIG. 7E). The stopper drive unit 32 is, but is not limited to, a motor or an air cylinder, for example. The first state C1 is a state in which the stopper 30 protrudes from the mounting surface 20s of the mounting portion 20 toward the side on which the box-making sheet S is mounted. The second state C2 is a state in which the stopper 30 does not protrude from the mounting surface 20s of the mounting portion 20 to the side on which the box-making sheet S is mounted. When the stopper 30 is in the first state C1, there is a possibility that the end portion of the box-making sheet S on which the box-making sheet S is placed on the mounting surface 20s of the mounting portion 20 comes into contact with the stopper 30. There is. In particular, when the posture of the mounting portion 20 is changed from the first posture P1 to a posture tilted forward while the stopper 30 is in the first state C1, the stopper 30 is moved to the mounting surface 20s of the mounting portion 20. The box-making sheet S placed in the box-making sheet S is supported from below. On the other hand, when the stopper 30 is in the second state C2, the box-making sheet S does not come into contact with the stopper 30 even if the box-making sheet S is placed on the mounting surface 20s of the mounting portion 20.
　供給部６０（具体的には第１駆動部６２）は、ストッパ駆動部３２がストッパ３０の状態を第１状態Ｃ１にした状態で、載置部２０の姿勢を、第１姿勢Ｐ１から第２姿勢Ｐ２に変更することが好ましい。また、ストッパ駆動部３２は、供給部６０（具体的には第１駆動部６２）が載置部２０の姿勢を第２姿勢Ｐ２に変更した後に、ストッパ３０の状態を第１状態Ｃ１から第２状態Ｃ２に変更することが好ましい。このように構成されることで、整然とした姿勢で貯留部１１２に製函用シートＳを供給することができる。 The supply unit 60 (specifically, the first drive unit 62) changes the posture of the mounting unit 20 from the first posture P1 to the second in a state where the stopper drive unit 32 changes the state of the stopper 30 to the first state C1. It is preferable to change to the posture P2. Further, in the stopper drive unit 32, after the supply unit 60 (specifically, the first drive unit 62) changes the posture of the mounting unit 20 to the second posture P2, the state of the stopper 30 is changed from the first state C1 to the first state C1. It is preferable to change to the two-state C2. With this configuration, the box-making sheet S can be supplied to the storage unit 112 in an orderly posture.
　（４－２）載置部ガイド及びガイド駆動部
　載置部ガイド４０は、第１方向Ｄ１（本実施形態では前後方向）に沿って延びる部材である。第１方向Ｄ１は、載置部２０に、複数の製函用シートＳが外部から供給される方向である。載置部ガイド４０は、載置部２０に対して、第１方向Ｄ１と直交する第２方向Ｄ２（本実施形態では左右方向）における両側に配置されている。載置部ガイド４０は、載置部２０の左側に配置される第１ガイド４２と、載置部２０の右側に配置される第２ガイド４４と、を含む。載置部ガイド４０は、載置部２０上の製函用シートＳの左右方向（第２方向Ｄ２）の位置ずれを規制し、載置部２０上の製函用シートＳの前方への移動をガイドする部材である。 (4-2) Mounting portion guide and guide driving portion The mounting portion guide 40 is a member extending along the first direction D1 (in the present embodiment, the front-rear direction). The first direction D1 is a direction in which a plurality of box-making sheets S are supplied to the mounting portion 20 from the outside. The mounting portion guides 40 are arranged on both sides of the mounting portion 20 in the second direction D2 (left-right direction in the present embodiment) orthogonal to the first direction D1. The mounting portion guide 40 includes a first guide 42 arranged on the left side of the mounting portion 20 and a second guide 44 arranged on the right side of the mounting portion 20. The mounting portion guide 40 regulates the positional deviation of the box-making sheet S on the mounting portion 20 in the left-right direction (second direction D2), and moves the box-making sheet S on the mounting portion 20 forward. It is a member that guides.
　第１ガイド４２は、例えば図示しないガイドレールに沿って第２方向Ｄ２（左右方向）に移動可能である。第１ガイド４２は、ガイド駆動部４３により第２方向Ｄ２に移動させられる。ガイド駆動部４３は、限定するものではないが、例えばサーボモータである。第１ガイド４２は、後述するような方法で、第２方向Ｄ２において、貯留部ガイド１１６の位置と載置部ガイド４０の第１ガイド４２の位置とが一致するように位置調整される。 The first guide 42 can move in the second direction D2 (left-right direction) along, for example, a guide rail (not shown). The first guide 42 is moved in the second direction D2 by the guide drive unit 43. The guide drive unit 43 is, but is not limited to, a servomotor, for example. The position of the first guide 42 is adjusted so that the position of the storage portion guide 116 and the position of the first guide 42 of the mounting portion guide 40 coincide with each other in the second direction D2 by a method as described later.
　前述のように、貯留部ガイド１１６の第２方向Ｄ２における位置は、製函用シートＳのサイズに応じて変更されている。ガイド駆動部４３が、第２方向Ｄ２において、貯留部ガイド１１６の位置と、載置部ガイド４０の第１ガイド４２の位置と、を一致させることで、第１ガイド４２の位置を、使用する製函用シートＳのサイズに合わせた位置に調整することができる。 As described above, the position of the reservoir guide 116 in the second direction D2 is changed according to the size of the box-making sheet S. The guide drive unit 43 uses the position of the first guide 42 by matching the position of the storage unit guide 116 with the position of the first guide 42 of the mounting unit guide 40 in the second direction D2. It can be adjusted to a position that matches the size of the box-making sheet S.
　なお、ガイド駆動部４３は、第１ガイド４２を第２方向Ｄ２（左右方向）に移動させる際、載置部２０も第１ガイド４２と連動して第２方向Ｄ２（左右方向）に移動させることが好ましい。言い換えれば、ガイド駆動部４３は、第１ガイド４２を左方向に移動させる際には載置部２０も左方向に移動され、第１ガイド４２を右方向に移動させる際には載置部２０も右方向に移動させることが好ましい。ただし、載置部２０の移動量は、第１ガイド４２の移動量の半分であることが好ましい。このように構成されることで、製函用シートＳのサイズによらず、製函用シートＳの重心位置の下方に載置部２０を配置することができる。載置部２０の移動量を第１ガイド４２の移動量の半分とするため、例えば、第１ガイド４２と載置部２０とは、図２のようにスライドリンク機構４６により接続されている。このようなスライドリンク機構４６を利用することで、ガイド駆動部４３が第１ガイド４２を距離Ｄだけ移動させるとき、載置部２０を、第１ガイド４２と同一方向に、距離１／２Ｄだけ移動させることができる。 When the guide drive unit 43 moves the first guide 42 in the second direction D2 (left-right direction), the mounting unit 20 also moves in the second direction D2 (left-right direction) in conjunction with the first guide 42. Is preferable. In other words, in the guide drive unit 43, the mounting unit 20 is also moved to the left when the first guide 42 is moved to the left, and the mounting unit 20 is moved to the right when the first guide 42 is moved to the right. It is preferable to move it to the right. However, the amount of movement of the mounting portion 20 is preferably half the amount of movement of the first guide 42. With this configuration, the mounting portion 20 can be arranged below the position of the center of gravity of the box-making sheet S regardless of the size of the box-making sheet S. In order to make the moving amount of the mounting portion 20 half the moving amount of the first guide 42, for example, the first guide 42 and the mounting portion 20 are connected by a slide link mechanism 46 as shown in FIG. By using such a slide link mechanism 46, when the guide drive unit 43 moves the first guide 42 by the distance D, the mounting unit 20 is moved in the same direction as the first guide 42 by a distance of 1 / 2D. Can be moved.
　また、第２ガイド４４も、例えば図示しないガイドレールに沿って、手動で又は自動で第２方向Ｄ２（左右方向）に移動可能であってもよい。 Further, the second guide 44 may also be manually or automatically movable in the second direction D2 (left-right direction) along, for example, a guide rail (not shown).
　なお、限定するものではないが、第１ガイド４２は前後方向には不動である。一方で、第２ガイド４４は、載置部２０の前後方向に合わせて前後に移動する。 Although not limited, the first guide 42 is immovable in the front-back direction. On the other hand, the second guide 44 moves back and forth according to the front-back direction of the mounting portion 20.

Further, the controller 90 may transmit a predetermined signal to the system controller 5 when supplying the box-making sheet S to the box-making device 100.
　コントローラ９０は、ＣＰＵが記憶装置に記憶されている制御用プログラムを実行することで、姿勢制御部９１、移動制御部９２、判断部９４、ストッパ制御部９６、及びガイド位置調整部９８として機能する。 The controller 90 functions as an attitude control unit 91, a movement control unit 92, a determination unit 94, a stopper control unit 96, and a guide position adjustment unit 98 by executing a control program stored in the storage device by the CPU. ..
　姿勢制御部９１は、供給部６０の第１駆動部６２の動作を制御する。 The attitude control unit 91 controls the operation of the first drive unit 62 of the supply unit 60.

In other words, the movement control unit 92 determines at which position in the front-rear direction the posture of the mounting unit 20 is changed to the second posture P2, and the supply unit so that the mounting unit 20 moves to the determined position. It controls the operation of the second drive unit 64 of 60.

The flowchart of FIG. 8 is an example of the position adjustment process of the first guide 42 of the mounting portion guide 40, and may be appropriately changed as long as there is no contradiction. The step in the dotted line is not a process executed by the sheet supply device 10, but a process executed by the box-making device 100 (executed by the system controller 5).
　ステップＳ１１では、箱詰めシステム１の図示しない入力部に製函用シートＳの仕様変更（サイズ変更）が入力される。システムコントローラ５は、入力された情報（例えば製函用シートＳのサイズの情報）を取得する。 In step S11, the specification change (size change) of the box-making sheet S is input to the input unit (not shown) of the boxing system 1. The system controller 5 acquires the input information (for example, the size information of the box-making sheet S).
　ステップＳ１２では、システムコントローラ５が、ガイド駆動部１１６ａを制御して、製函用シートＳのサイズに応じて、貯留部ガイド１１６の位置を調整する。 In step S12, the system controller 5 controls the guide drive unit 116a to adjust the position of the storage unit guide 116 according to the size of the box-making sheet S.

　（６）製函用シート供給時のシート供給装置の動作
　製函用シートＳの供給時のシート供給装置１０の動作について図９のフローチャート及び図６Ａ～図６Ｆ及び図７Ａ～図７Ｆに基づいて説明する。なお、点線内のステップは、シート供給装置１０による処理ではなく、製函装置１００により実行される（システムコントローラ５により実行される）処理である。なお、以下で説明する製函用シートＳの供給時のシート供給装置１０の動作は、一例に過ぎず、矛盾の無い範囲で適宜変更されてもよい。例えば、矛盾の無い範囲で、ステップの順番は変更されてもよい。 (6) Operation of the sheet supply device when supplying the box-making sheet The operation of the sheet supply device 10 when supplying the box-making sheet S is based on the flowchart of FIG. 9 and FIGS. 6A to 6F and 7A to 7F. explain. The step in the dotted line is not a process performed by the sheet supply device 10, but a process executed by the box making device 100 (executed by the system controller 5). The operation of the sheet supply device 10 at the time of supplying the box-making sheet S described below is only an example, and may be appropriately changed as long as there is no contradiction. For example, the order of the steps may be changed to the extent that there is no contradiction.
　以下の説明の前提として、処理の開始時点において、載置部２０は第１姿勢Ｐ１であり、載置部２０は、前後方向において、製函用シートＳを受け取る際の初期位置に配置されているものとする。また、載置部２０のストッパ３０は、第１状態Ｃ１にあるものとする。また、製函装置１００のプッシャ１１４は、当接位置に配置されているものとする。また、貯留部１１２は、製函用シートＳを供給可能な状態（製函用シートＳの供給を受け入れ可能なスペースがある状態）であるものとする。 As a premise of the following description, at the start of the process, the mounting unit 20 is in the first posture P1, and the mounting unit 20 is arranged in the front-rear direction at the initial position when receiving the box-making sheet S. It is assumed that there is. Further, it is assumed that the stopper 30 of the mounting portion 20 is in the first state C1. Further, it is assumed that the pusher 114 of the box making device 100 is arranged at the contact position. Further, it is assumed that the storage unit 112 is in a state where the box-making sheet S can be supplied (a state in which there is a space capable of accepting the supply of the box-making sheet S).
　ステップＳ１では、第１姿勢Ｐ１の載置部２０が製函用シートＳを受け取る（図６Ａ及び図７Ａ参照）。載置部２０が製函用シートＳを受け取ったことは、例えば、載置部２０上の製函用シートＳを検知する各種センサを用いて検知されればよい。 In step S1, the mounting portion 20 of the first posture P1 receives the box-making sheet S (see FIGS. 6A and 7A). The receipt of the box-making sheet S by the mounting unit 20 may be detected, for example, by using various sensors that detect the box-making sheet S on the mounting unit 20.
　ステップＳ２では、姿勢制御部９１が、供給部６０の第１駆動部６２を制御して、載置部２０の姿勢を第１姿勢Ｐ１から第３姿勢Ｐ３に変更する。この結果、載置部２０上の製函用シートＳは、重力により、ストッパ３０に当接する位置まで、載置部２０の載置面２０ｓの傾きに沿って前方へと（載置部２０の第２端２４側）に移動する（図７Ｂ参照）。 In step S2, the posture control unit 91 controls the first drive unit 62 of the supply unit 60 to change the posture of the mounting unit 20 from the first posture P1 to the third posture P3. As a result, the box-making sheet S on the mounting portion 20 moves forward along the inclination of the mounting surface 20s of the mounting portion 20 to a position where it abuts on the stopper 30 due to gravity (the mounting portion 20). Move to the second end 24 side) (see FIG. 7B).
　次に、ステップＳ３では、判断部９４は、貯留部１１２に貯留されている複数の製函用シートＳのうち、最もシート供給装置１０の近くに配置されている製函用シートＳの位置を判断する。具体的には、判断部９４は、力付与機構１１４ａの検知結果（プッシャ１１４の位置）に基づいて、最もシート供給装置１０の近くに配置されている製函用シートＳの位置を判断する。 Next, in step S3, the determination unit 94 determines the position of the box-making sheet S that is closest to the sheet supply device 10 among the plurality of box-making sheets S stored in the storage unit 112. to decide. Specifically, the determination unit 94 determines the position of the box-making sheet S located closest to the sheet supply device 10 based on the detection result (position of the pusher 114) of the force applying mechanism 114a.
　そして、移動制御部９２は、判断部９４の判断結果に基づいて、第２姿勢変更位置を決定する。第２姿勢変更位置は、第１駆動部６２が載置部２０の姿勢を第２姿勢Ｐ２に変更する際に載置部２０が配置される、前後方向における位置である。移動制御部９２は、例えば、第１駆動部６２が載置部２０の姿勢を第３姿勢Ｐ３から第２姿勢Ｐ２へと変更した時に、載置部２０や載置部２０のストッパ３０が最もシート供給装置１０の近くに配置されている製函用シートＳに接触しないように第２姿勢変更位置を決定する。また、移動制御部９２は、例えば、第１駆動部６２が載置部２０の姿勢を第３姿勢Ｐ３から第２姿勢Ｐ２に変更した時に、載置部２０上に載置されている製函用シートＳが、最もシート供給装置１０の近くに配置されている製函用シートＳの近傍に供給されるように第２姿勢変更位置を決定する。 Then, the movement control unit 92 determines the second posture change position based on the determination result of the determination unit 94. The second posture change position is a position in the front-rear direction in which the mounting portion 20 is arranged when the first driving unit 62 changes the posture of the mounting portion 20 to the second posture P2. In the movement control unit 92, for example, when the first drive unit 62 changes the posture of the mounting unit 20 from the third posture P3 to the second posture P2, the mounting unit 20 and the stopper 30 of the mounting unit 20 are the most. The second posture change position is determined so as not to come into contact with the box-making sheet S arranged near the sheet supply device 10. Further, the movement control unit 92 is mounted on the mounting unit 20 when, for example, the first driving unit 62 changes the posture of the mounting unit 20 from the third posture P3 to the second posture P2. The second posture change position is determined so that the sheet S is supplied in the vicinity of the box-making sheet S located closest to the sheet supply device 10.
　次に、ステップＳ４では、移動制御部９２は、第２駆動部６４を制御して、載置部２０を決定した第２姿勢変更位置まで移動（前進）させる（図６Ｂ及び図７Ｃ参照）。 Next, in step S4, the movement control unit 92 controls the second drive unit 64 to move (advance) the mounting unit 20 to the determined second posture change position (see FIGS. 6B and 7C).
　次に、ステップＳ５では、システムコントローラ５は、プッシャ切換部１１４ｂの動作を制御して、プッシャ１１４を当接位置から退避位置へと移動させる（図６Ｃ参照）。 Next, in step S5, the system controller 5 controls the operation of the pusher switching unit 114b to move the pusher 114 from the contact position to the retracted position (see FIG. 6C).
　ステップＳ６では、姿勢制御部９１が、供給部６０の第１駆動部６２を制御して、載置部２０の姿勢を第３姿勢Ｐ３から第２姿勢Ｐ２に変更する（図６Ｄ及び図７Ｄ参照）。 In step S6, the posture control unit 91 controls the first drive unit 62 of the supply unit 60 to change the posture of the mounting unit 20 from the third posture P3 to the second posture P2 (see FIGS. 6D and 7D). ).
　ステップＳ７では、ストッパ制御部９６が、ストッパ駆動部３２の動作を制御して、ストッパ３０の状態を第２状態Ｃ２に変更する（図６Ｅ及び図７Ｅ参照）。 In step S7, the stopper control unit 96 controls the operation of the stopper drive unit 32 to change the state of the stopper 30 to the second state C2 (see FIGS. 6E and 7E).
　ステップＳ８では、移動制御部９２は、第２駆動部６４を制御して、載置部２０を前後方向における初期位置まで移動（後退）させる（図６Ｆ及び図７Ｆ参照）。 In step S8, the movement control unit 92 controls the second drive unit 64 to move (retract) the mounting unit 20 to the initial position in the front-rear direction (see FIGS. 6F and 7F).
　ステップＳ９では、ストッパ制御部９６が、ストッパ駆動部３２の動作を制御して、ストッパ３０の状態を第１状態Ｃ１に変更する（図６Ｆ及び図７Ｆ参照）。 In step S9, the stopper control unit 96 controls the operation of the stopper drive unit 32 to change the state of the stopper 30 to the first state C1 (see FIGS. 6F and 7F).
　ステップＳ１０では、姿勢制御部９１が、供給部６０の第１駆動部６２を制御して、載置部２０の姿勢を第２姿勢Ｐ２から第１姿勢Ｐ１に変更する（図６Ｆ及び図７Ｆ参照）。 In step S10, the posture control unit 91 controls the first drive unit 62 of the supply unit 60 to change the posture of the mounting unit 20 from the second posture P2 to the first posture P1 (see FIGS. 6F and 7F). ).
