　吸収性物品の製造装置１は、使い捨ておむつや生理用ナプキン等の吸収性物品を構成する複数の連続する資材（例えば不織布やフィルム等）をそれぞれ繰り出す複数の資材供給装置２と、複数の資材供給装置２からそれぞれ繰り出された複数の資材を吸収性物品に加工する加工装置３と、ターンバー４とを有する。吸収性物品の製造装置１は、互いに直交するＸ方向、Ｙ方向、及び、鉛直方向を有する。なお、Ｘ方向及びＹ方向は直交するに限らず交差していればよい。 <Absorbent article manufacturing apparatus 1>
Absorbent article manufacturing apparatus 1 includes a plurality of material supply apparatuses 2 that respectively feed out a plurality of continuous materials (for example, non-woven fabrics, films, etc.) constituting absorbent articles such as disposable diapers and sanitary napkins, and a plurality of material supplies A processing device 3 for processing a plurality of materials fed from the device 2 into absorbent articles and a turn bar 4 are provided. The absorbent article manufacturing apparatus 1 has an X direction, a Y direction, and a vertical direction that are orthogonal to each other. Note that the X direction and the Y direction are not limited to being orthogonal to each other, but may be crossed.
　図２に示すように、加工装置３はその長手方向がＹ方向に沿って配置されている。資材供給装置２はその長手方向がＸ方向に沿って配置されており、複数の資材供給装置２はＹ方向に間隔を空けて配置されている。つまり、加工装置３と複数の資材供給装置２とが直角に配置されている。資材供給装置２ではＸ方向に資材５が搬送される。資材供給装置２から繰り出された資材５は、Ｘ方向に搬送された後、ターンバー４によって搬送方向が変更され、搬送方向をＹ方向として加工装置３に供給される。加工装置３ではＹ方向に資材５が搬送されつつ吸収性物品へと加工される。 As shown in FIG. 2, the longitudinal direction of the processing apparatus 3 is arranged along the Y direction. The material supply device 2 has a longitudinal direction arranged along the X direction, and the plurality of material supply devices 2 are arranged at intervals in the Y direction. That is, the processing device 3 and the plurality of material supply devices 2 are arranged at right angles. In the material supply apparatus 2, the material 5 is conveyed in the X direction. After the material 5 fed out from the material supply device 2 is conveyed in the X direction, the conveyance direction is changed by the turn bar 4 and is supplied to the processing device 3 with the conveyance direction set as the Y direction. In the processing apparatus 3, the material 5 is processed into an absorbent article while being conveyed in the Y direction.
　ターンバー４は、図２に示すように、その軸方向がＸ方向及びＹ方向に対して４５°傾斜した方向に沿って配置される。ターンバー４に資材５が掛け回されると、資材５の搬送方向がＸ方向からＹ方向へと変更される。なお、図１では、ターンバー４に掛け回された資材５が、搬送ローラー７ａに掛け回されて鉛直方向に搬送され、鉛直方向の位置が調整された後に、搬送ローラー７ｂに掛け回されてＹ方向に搬送されている。 As shown in FIG. 2, the turn bar 4 is arranged along a direction in which the axial direction is inclined by 45 ° with respect to the X direction and the Y direction. When the material 5 is wound around the turn bar 4, the conveyance direction of the material 5 is changed from the X direction to the Y direction. In FIG. 1, the material 5 hung on the turn bar 4 is hung on the conveyance roller 7 a and conveyed in the vertical direction, and after the position in the vertical direction is adjusted, it is hung on the conveyance roller 7 b and Y. Being conveyed in the direction.
　資材供給装置２にセットされる資材は、連続する資材５が紙管にコイル状に巻かれた資材コイル６の形態を成す。図２に示すように予備の資材コイル６は、資材供給装置２に対してＸ方向における加工装置３側とは反対側の通路８から搬送される。そして、資材供給装置２と通路８との間に予備の資材コイル６が配置される。 The material set in the material supply device 2 is in the form of a material coil 6 in which a continuous material 5 is wound around a paper tube in a coil shape. As shown in FIG. 2, the spare material coil 6 is conveyed with respect to the material supply device 2 from a passage 8 on the side opposite to the processing device 3 side in the X direction. A spare material coil 6 is disposed between the material supply device 2 and the passage 8.
　なお、加工装置３と複数の資材供給装置２とを直角に配置するに限らず、各装置２，３の長手方向を揃え、資材５の搬送方向を揃えてもよい。但しその場合、例えば資材供給装置２の短手方向において、資材コイル６をセットする作業者の作業スペース分だけ離れた位置に予備の資材コイル６を配置することになる。 Note that the processing device 3 and the plurality of material supply devices 2 are not limited to be arranged at right angles, but the longitudinal directions of the devices 2 and 3 may be aligned, and the conveyance direction of the material 5 may be aligned. However, in that case, for example, in the short direction of the material supply device 2, the spare material coil 6 is arranged at a position separated by the work space of the operator who sets the material coil 6.
　そのため、本実施形態のように各長手方向が交差するように加工装置３と資材供給装置２を配置するとよい。つまり、資材供給装置２からＸ方向（第１方向）を搬送方向として送られる資材５（先行の資材又は後行の資材）が、平面視でＸ方向に交差するＹ方向（第２方向）に搬送方向を変更して加工装置３へ送られるようにするとよい。そうすることで、図２に示すように資材供給装置２の近くに予備の資材コイル６を配置できる。よって、作業者が資材コイル６のセット作業を効率よく行える。また、資材コイル６のセット時に使用されるクレーン４０（後述）を小型化できる。 Therefore, the processing device 3 and the material supply device 2 may be arranged so that the respective longitudinal directions intersect as in the present embodiment. That is, the material 5 (the preceding material or the following material) sent from the material supply device 2 with the X direction (first direction) as the transport direction is in the Y direction (second direction) intersecting the X direction in plan view. The conveying direction may be changed so that the sheet is sent to the processing apparatus 3. By doing so, the spare material coil 6 can be arrange | positioned near the material supply apparatus 2 as shown in FIG. Therefore, the worker can efficiently perform the setting work of the material coil 6. Moreover, the crane 40 (after-mentioned) used when the material coil 6 is set can be reduced in size.
＜資材供給装置２＞
　資材供給装置２には２つの資材コイル６がセットされる。そして資材供給装置２は、一方の資材コイル６ａから連続して繰り出される先行の資材５ａに、別の資材コイル６ｂの資材を後行の資材５ｂとして接合することによって、先行の資材５ａに連続させて後行の資材５ｂを加工装置３に供給する。そのために資材供給装置２は、図１に示す枠体２１と、装置の床部に立設する支持部材２２と、旋回部材３０と、接合ユニット２３と、切断ユニット２４と、テンションコントローラー２５と、クレーン４０と、図３に示す支持ユニット５０と、これらを制御する制御部２６とを有する。 <Material supply device 2>
Two material coils 6 are set in the material supply device 2. And the material supply apparatus 2 makes the preceding material 5a continue by joining the material of another material coil 6b as the succeeding material 5b to the preceding material 5a continuously drawn out from one material coil 6a. The subsequent material 5b is supplied to the processing device 3. Therefore, the material supply device 2 includes a frame body 21 shown in FIG. 1, a support member 22 erected on the floor of the device, a turning member 30, a joining unit 23, a cutting unit 24, a tension controller 25, It has the crane 40, the support unit 50 shown in FIG. 3, and the control part 26 which controls these.
　旋回部材３０は、帯板状の部材であり、その中央部にＹ方向に沿った旋回用回転軸３１が設けられている。旋回用回転軸３１は支持部材２２に回転可能に支持され、不図示のサーボモーターの駆動によって回転する。旋回用回転軸３１の回転により、旋回部材３０は旋回用回転軸３１の周りを旋回する。また旋回部材３０の長手方向の両端部にはＹ方向に沿った一対の繰り出し用回転軸３２，３３が設けられている。一対の繰り出し用回転軸３２，３３の一方に先行の資材コイル６ａがセットされ、他方に後行の資材コイル６ｂがセットされる。旋回部材３０が１８０°旋回すると、一対の繰り出し用回転軸３２，３３も共に旋回する。そうすると、一対の繰り出し用回転軸３２，３３の位置が入れ替わり、先行の資材コイル６ａと後行の資材コイル６ｂの位置も入れ替わる。 The turning member 30 is a strip-shaped member, and a turning rotary shaft 31 along the Y direction is provided at the center thereof. The turning rotary shaft 31 is rotatably supported by the support member 22 and is rotated by driving a servo motor (not shown). Due to the rotation of the turning rotary shaft 31, the turning member 30 turns around the turning rotary shaft 31. In addition, a pair of feeding rotary shafts 32 and 33 along the Y direction are provided at both ends of the turning member 30 in the longitudinal direction. The preceding material coil 6a is set on one of the pair of feeding rotating shafts 32 and 33, and the succeeding material coil 6b is set on the other. When the turning member 30 turns 180 °, the pair of feeding rotation shafts 32 and 33 also turn together. Then, the positions of the pair of feeding rotary shafts 32 and 33 are switched, and the positions of the preceding material coil 6a and the succeeding material coil 6b are also switched.
　また、図４に示すように、旋回部材３０には一対の繰り出し用回転軸３２，３３をそれぞれ駆動回転させる一対のサーボモーター３４，３４が固定されている。各サーボモーター３４，３４の出力軸３４ａ，３４ａ、及び、各繰り出し用回転軸３２，３３の一端部に、プーリ３５，３５が掛け回されており、サーボモーター３４，３４の回転力が繰り出し用回転軸３２，３３に伝達される。繰り出し用回転軸３２，３３が回転すると、資材コイル６ａ，６ｂも回転し、資材コイル６ａ，６ｂから資材５が繰り出される。 As shown in FIG. 4, a pair of servo motors 34, 34 that drive and rotate the pair of feeding rotary shafts 32, 33 are fixed to the turning member 30. Pulleys 35 and 35 are wound around one end of the output shafts 34a and 34a of the servo motors 34 and 34 and the rotary shafts 32 and 33 for feeding, and the rotational force of the servo motors 34 and 34 is for feeding. It is transmitted to the rotating shafts 32 and 33. When the feeding rotary shafts 32 and 33 rotate, the material coils 6a and 6b also rotate, and the material 5 is fed from the material coils 6a and 6b.
　また、繰り出し用回転軸３２，３３の一端部は軸受け３６，３６及びブラケット３７，３７を介して旋回部材３０に支持されているが、他端部は旋回部材３０に支持されていない。つまり、繰り出し用回転軸３２，３３及び資材コイル６は旋回部材３０に回転可能且つ片持ち状に支持される。但し、繰り出し用回転軸３２，３３の他端部にも軸受け３８，３８及びブラケット３９，３９が設けられている。これは後述する支持ユニット５０が、繰り出し用回転軸３２，３３の他端部を回転可能に支持するためである。なお、繰り出し用回転軸３２，３３としてエアシャフトを例示できる。エアシャフトは、シャフトに設けられた膨張体がエアの注入により突出するため、資材コイル６ａ，６ｂを位置ずれなく保持できる。 Further, one end portions of the feeding rotary shafts 32 and 33 are supported by the turning member 30 via bearings 36 and 36 and brackets 37 and 37, but the other end portions are not supported by the turning member 30. That is, the feeding rotary shafts 32 and 33 and the material coil 6 are rotatably supported by the turning member 30 and cantilevered. However, bearings 38 and 38 and brackets 39 and 39 are also provided at the other end portions of the feeding rotary shafts 32 and 33. This is because the support unit 50 to be described later rotatably supports the other end portions of the feeding rotary shafts 32 and 33. An air shaft can be exemplified as the feeding rotary shafts 32 and 33. The air shaft can hold the material coils 6a and 6b without misalignment because the expansion body provided on the shaft protrudes by air injection.
　接合ユニット２３は、一対の繰り出し用回転軸３２，３３の一方の駆動によって回転する後行の資材コイル６ｂの外周面に向けて、他方の繰り出し用回転軸３２，３３の駆動によって先行の資材コイル６ａから繰り出される先行の資材５ａの押し付け動作を行い、先行の資材５ａに後行の資材５ｂを接合する。なお、後行の資材コイル６ｂの先端部には、その外周面に接合用の両面テープが設けられているものとする。 The joining unit 23 moves toward the outer peripheral surface of the succeeding material coil 6b that rotates by driving one of the pair of feeding rotary shafts 32 and 33, and drives the other material rotating shaft 32 and 33 to drive the preceding material coil. A pressing operation of the preceding material 5a fed out from 6a is performed, and the succeeding material 5b is joined to the preceding material 5a. Here, it is assumed that a double-sided adhesive tape is provided on the outer peripheral surface of the distal end portion of the subsequent material coil 6b.
　そのために、接合ユニット２３は、Ｙ方向に沿った回転軸２３ａ回りに揺動可能に支持されたアーム部材２３ｂと、アーム部材２３ｂの揺動端部においてＹ方向に沿った回転軸２３ｃに回転可能に支持されたプレスロール２３ｄと、アーム部材２３ｂを駆動するエアシリンダー等のアクチュエータ２３ｅとを有する。アーム部材２３ｂの揺動動作により、プレスロール２３ｄは、後行の資材コイル６ｂの外周面に接触する接合位置と、接合位置から離れた退避位置との間を移動可能である。なお、プレスロール２３ｄは、資材５の接触によって連れ回る従動ロールであっても、サーボモーター等の駆動源により回転する駆動ロールであってもよい。 For this purpose, the joining unit 23 can be rotated to the rotation shaft 23c along the Y direction at the swing end of the arm member 23b, and the arm member 23b supported so as to swing around the rotation shaft 23a along the Y direction. And a press roll 23d supported by the actuator 23e and an actuator 23e such as an air cylinder for driving the arm member 23b. By the swinging motion of the arm member 23b, the press roll 23d can move between a joining position that contacts the outer peripheral surface of the succeeding material coil 6b and a retracted position that is away from the joining position. The press roll 23d may be a driven roll that is rotated by contact with the material 5, or may be a drive roll that is rotated by a drive source such as a servo motor.
　切断ユニット２４は、先行の資材５ａと後行の資材５ｂの接合位置よりも上流側において、先行の資材５ａを切断し、先行の資材５ａの加工装置３への供給を終了する。そのために、切断ユニット２４は、Ｙ方向に沿った回転軸２４ａ回りに揺動可能に支持されたアーム部材２４ｂと、アーム部材２４ｂの揺動端部に固定されたカッター刃２４ｃと、アーム部材２４ｂを駆動するエアシリンダー等のアクチュエータ２４ｄとを有する。アーム部材２４ｂの揺動動作により、カッター刃２４ｃは、先行の資材５ａに接触する切断位置と、切断位置から離れた待機位置との間を移動可能である。 The cutting unit 24 cuts the preceding material 5a upstream of the joining position of the preceding material 5a and the succeeding material 5b, and ends the supply of the preceding material 5a to the processing device 3. For this purpose, the cutting unit 24 includes an arm member 24b supported so as to be swingable about a rotation shaft 24a along the Y direction, a cutter blade 24c fixed to the swing end of the arm member 24b, and an arm member 24b. And an actuator 24d such as an air cylinder for driving the motor. By the swinging motion of the arm member 24b, the cutter blade 24c is movable between a cutting position that contacts the preceding material 5a and a standby position away from the cutting position.
　なお、この実施形態では、先行の資材５ａと後行の資材５ｂの接合位置を固定とする。具体的には、Ｘ方向上流側の繰り出し用回転軸（図１では３２）が支持する先行の資材コイル６ａから繰り出される先行の資材５ａと、Ｘ方向下流側の繰り出し用回転軸（図１では３３）が支持する後行の資材コイル６ｂの外周面とが、接合される。また、繰り出し用回転軸３２，３３は反時計回りに回転し、資材コイル６ａ，６ｂの下方から資材５ａ，５ｂが繰り出されるとする。よって、接合ユニット２３及び切断ユニット２４は資材コイル６ａ，６ｂの下方に位置し、旋回部材３０は時計周りに回転する。また、接合ユニット２３及び切断ユニット２４は旋回部材３０とともに旋回しないものとする。 In this embodiment, the joining position of the preceding material 5a and the succeeding material 5b is fixed. Specifically, the preceding material 5a fed from the preceding material coil 6a supported by the feeding rotation shaft on the upstream side in the X direction (32 in FIG. 1) and the feeding rotation shaft on the downstream side in the X direction (in FIG. 1). 33) is joined to the outer peripheral surface of the subsequent material coil 6b supported by 33). Further, it is assumed that the feeding rotary shafts 32 and 33 rotate counterclockwise, and the materials 5a and 5b are fed out from below the material coils 6a and 6b. Therefore, the joining unit 23 and the cutting unit 24 are located below the material coils 6a and 6b, and the turning member 30 rotates clockwise. Further, it is assumed that the joining unit 23 and the cutting unit 24 do not turn together with the turning member 30.
　テンションコントローラー２５は、接合ユニット２３よりも下流側に配置され、テンションコントローラー２５を出た資材５の張力が目標値となるように調整する。そのために、テンションコントローラー２５は、所謂ダンサーローラーの構成を採用し、一対の固定ローラー２５ａ，２５ａと、一対の固定ローラー２５ａ，２５ａ間の資材５の長さ（ループの大きさ）を調整する可動ローラー２５ｂとを有する。資材５の張力が目標値よりも小さい場合、一対の固定ローラー２５ａ，２５ａ間の資材５の長さが長くなるように可動ローラー２５ｂは移動する。逆に資材５の張力が目標値よりも大きい場合には、一対の固定ローラー２５ａ，２５ａ間の資材５の長さが短くなるように可動ローラー２５ｂは移動する。 The tension controller 25 is arranged on the downstream side of the joining unit 23 and adjusts so that the tension of the material 5 exiting the tension controller 25 becomes a target value. For this purpose, the tension controller 25 adopts a so-called dancer roller configuration and is movable to adjust the length (loop size) of the pair of fixed rollers 25a and 25a and the material 5 between the pair of fixed rollers 25a and 25a. And a roller 25b. When the tension | tensile_strength of the material 5 is smaller than a target value, the movable roller 25b moves so that the length of the material 5 between a pair of fixed rollers 25a and 25a may become long. Conversely, when the tension of the material 5 is larger than the target value, the movable roller 25b moves so that the length of the material 5 between the pair of fixed rollers 25a and 25a is shortened.
　クレーン４０は、図５Ａに示すように、資材コイル６を昇降するホイスト４１（吊り装置）と、ホイスト４１が設けられた長尺状のジブ４２と、ジブ４２を旋回可能に支持する支持部４３とを有する。支持部４３は資材供給装置２の枠体２１の上部に設けられている。ジブ４２は、資材供給装置２のＹ方向における側面２ａのうち資材コイル６がセットされる側に突き出ている。また、ジブ４２は、Ｘ方向及びＹ方向に沿う水平面上を、支持部４３との連結金具４４を軸に旋回する。ホイスト４１は鉛直方向に昇降するとともに、ジブ４２の長手方向に移動可能である。なお、支持部４３に対するホイスト４１の相対位置がジブ４２の長手方向に移動可能であればよく、例えばジブ４２が長手方向に伸縮してもよい。 As shown in FIG. 5A, the crane 40 includes a hoist 41 (suspending device) that lifts and lowers the material coil 6, a long jib 42 provided with the hoist 41, and a support portion 43 that supports the jib 42 in a turnable manner. And have. The support portion 43 is provided on the upper portion of the frame body 21 of the material supply device 2. The jib 42 protrudes from the side surface 2a in the Y direction of the material supply device 2 to the side on which the material coil 6 is set. Further, the jib 42 pivots on a horizontal plane along the X direction and the Y direction, with the connecting bracket 44 with the support portion 43 as an axis. The hoist 41 moves up and down in the vertical direction and is movable in the longitudinal direction of the jib 42. In addition, the relative position of the hoist 41 with respect to the support part 43 should just be movable to the longitudinal direction of the jib 42, for example, the jib 42 may expand and contract in the longitudinal direction.
　このような構成のクレーン４０を資材供給装置２に設けることで、例えば図２に示すように資材供給装置２のＸ方向における側面の隣に配置された予備の資材コイル６を作業者が繰り出し用回転軸３２，３３に容易にセットできる。なお、資材コイル６のセット方法について説明すると、作業者は先ず予備の資材コイル６上までジブ４２を旋回するとともにホイスト４１を下降する。そして、作業者はホイスト４１が有するフック４６に固定された昇降用の治具４５に予備の資材コイル６を取り付ける。次に、作業者はジブ４２を旋回するとともにホイスト４１で資材コイル６を吊り上げ、資材コイル６の紙管と繰り出し用回転軸３２，３３の位置合わせを行う。その後、作業者はホイスト４１をジブ４２の長手方向に移動し、資材コイル６の紙管を繰り出し用回転軸３２，３３に差し込む。こうして資材コイル６のセットが完了する。 By providing the material supply device 2 with the crane 40 having such a configuration, for example, as shown in FIG. 2, the worker can feed the spare material coil 6 arranged next to the side surface in the X direction of the material supply device 2. It can be easily set on the rotary shafts 32 and 33. The method for setting the material coil 6 will be described. First, the operator turns the jib 42 over the spare material coil 6 and lowers the hoist 41. Then, the worker attaches the spare material coil 6 to the lifting jig 45 fixed to the hook 46 of the hoist 41. Next, the operator turns the jib 42 and lifts the material coil 6 with the hoist 41 to align the paper tube of the material coil 6 with the feeding rotary shafts 32 and 33. Thereafter, the operator moves the hoist 41 in the longitudinal direction of the jib 42 and inserts the paper tube of the material coil 6 into the feeding rotary shafts 32 and 33. Thus, the setting of the material coil 6 is completed.
　また、前述のように、吸収性物品の製造装置１は複数の資材供給装置２を有する。そして、複数の資材供給装置２は図２に示すように、資材コイル６を昇降するクレーン４０を個別に有する。そのため、頻繁に資材コイル６のセットを行う場合や、資材コイル６のセットに掛けられる時間が短い場合等に、資材コイル６のセットのタイミングが別の資材供給装置２と重複していても、別の資材供給装置２でのセットに合わせてクレーン４０を使用する必要がない。よって、加工装置３を停止することなく資材コイル６のセットを行える。但しこれに限らず、複数の資材供給装置２でクレーン４０を共有してもよい。 Further, as described above, the absorbent article manufacturing apparatus 1 includes a plurality of material supply apparatuses 2. And the some material supply apparatus 2 has the crane 40 which raises / lowers the material coil 6 separately, as shown in FIG. Therefore, even when the material coil 6 is frequently set, or when the time taken to set the material coil 6 is short, even if the timing of setting the material coil 6 overlaps with another material supply device 2, It is not necessary to use the crane 40 in accordance with a set in another material supply apparatus 2. Therefore, the material coil 6 can be set without stopping the processing device 3. However, the present invention is not limited to this, and the crane 40 may be shared by a plurality of material supply apparatuses 2.
　また、本実施形態では、図５Ｂに示すように、ジブ４２の旋回範囲４７が１８０度以下であり、資材供給装置２のＹ方向一方側の側面２ａから突き出るジブ４２が、その側面２ａよりもＹ方向の他方側に突き出ないようにクレーン４０が設置されている。つまり、ある資材供給装置２が有するクレーン４０のジブ４２の旋回範囲４７と、別の資材供給装置２が有するクレーン４０のジブ４２の旋回範囲４７とが、重複しないように設置されている。そうすることで、作業者が資材コイル６のセット時に、周囲のクレーン４０の衝突についての注意を払う必要がなくなり、作業効率を高められる。但しこれに限らずジブ４２の旋回範囲４７が重複していてもよい。 Moreover, in this embodiment, as shown in FIG. 5B, the turning range 47 of the jib 42 is 180 degrees or less, and the jib 42 protruding from the side surface 2a on one side in the Y direction of the material supply device 2 is more than the side surface 2a. A crane 40 is installed so as not to protrude to the other side in the Y direction. That is, the turning range 47 of the jib 42 of the crane 40 included in one material supply device 2 and the turning range 47 of the jib 42 of the crane 40 included in another material supply device 2 are installed so as not to overlap. By doing so, it is not necessary for the operator to pay attention to the collision of the surrounding crane 40 when setting the material coil 6, and work efficiency can be improved. However, the present invention is not limited to this, and the turning ranges 47 of the jib 42 may overlap.
　支持ユニット５０は、図３に示すように、支持部５１と、昇降用シリンダー５２と、本体部５３と、水平移動機構５４とを有する。支持部５１は、後行の資材コイル６ｂを支持する繰り出し用回転軸３２，３３の端部のうち旋回部材３０側とは反対側の端部を支持する。また、一対の繰り出し用回転軸３２，３３のうちＸ方向下流側に位置する繰り出し用回転軸３２，３３の端部を支持部５１が支持する。なお、旋回部材３０の旋回により一対の繰り出し用回転軸３２，３３の位置が入れ替わる。そのため、支持部５１は一対の繰り出し用回転軸３２，３３を交互に支持することになる。また、支持部５１は略直方体形状の部材であり、その上面のうちＹ方向の中央部が窪んでいる。その窪みはＹ方向に見て下方に湾曲しており、その窪みに、繰り出し用回転軸３２，３３及び軸受け３８を囲う中空円筒状のブラケット３９が嵌まる。 As shown in FIG. 3, the support unit 50 includes a support portion 51, a lifting cylinder 52, a main body portion 53, and a horizontal movement mechanism 54. The support portion 51 supports the end portion on the side opposite to the turning member 30 side among the end portions of the feeding rotary shafts 32 and 33 that support the subsequent material coil 6b. Further, the support portion 51 supports the end portions of the feeding rotary shafts 32 and 33 located on the downstream side in the X direction of the pair of feeding rotary shafts 32 and 33. Note that the position of the pair of feeding rotary shafts 32 and 33 is switched by the turning of the turning member 30. Therefore, the support portion 51 supports the pair of feeding rotary shafts 32 and 33 alternately. Moreover, the support part 51 is a substantially rectangular parallelepiped member, and the center part of the Y direction is depressed among the upper surfaces. The hollow is curved downward as viewed in the Y direction, and a hollow cylindrical bracket 39 surrounding the feeding rotary shafts 32 and 33 and the bearing 38 is fitted into the hollow.
　昇降用シリンダー５２は、支持部５１を下方から支持し、支持部５１を鉛直方向に昇降させる。本体部５３は、昇降用シリンダー５２を下方から支持する。水平移動機構５４は、Ｘ方向に沿ったガイドレール５４ａと、ガイドレール５４ａ上を往復移動するスライドテーブル５４ｂとを有する。スライドテーブル５４ｂは下方から本体部５３を支持し、支持部５１、昇降用シリンダー５２、及び本体部５３を、Ｘ方向に往復移動させる。なお、昇降用シリンダー５２としてはロッドシリンダー等を例示できる。また、水平移動機構５４としてはロッドレスシリンダーやボールねじ機構やラック・ピニオン機構等を例示できる。 The elevating cylinder 52 supports the support portion 51 from below and moves the support portion 51 up and down in the vertical direction. The main body 53 supports the lifting cylinder 52 from below. The horizontal movement mechanism 54 includes a guide rail 54a along the X direction and a slide table 54b that reciprocates on the guide rail 54a. The slide table 54b supports the main body 53 from below, and reciprocates the support 51, the lifting cylinder 52, and the main body 53 in the X direction. An example of the lifting cylinder 52 is a rod cylinder. Examples of the horizontal movement mechanism 54 include a rodless cylinder, a ball screw mechanism, a rack and pinion mechanism, and the like.
　支持部５１は、昇降用シリンダー５２及び水平移動機構５４によって、繰り出し用回転軸３２，３３の端部を支持する支持位置ｐ１と、支持位置ｐ１から離れた退避位置ｐ２との間を移動可能である。また、資材供給装置２の制御部２６は、昇降用シリンダー５２及び水平移動機構５４の駆動源（例えばサーボモーター等）と電気的に接続され、両者５２，５４の動きを制御する。つまり、本実施形態の資材供給装置２では、制御部２６による制御に従って、支持部５１が支持位置ｐ１と退避位置ｐ２との間を自動で移動する。そのため、作業者による支持部５１の移動処理を省略でき、作業者の作業効率を高められる。但しこれに限らず、作業者が手動で支持部５１を移動してもよい。 The support portion 51 can be moved between a support position p1 for supporting the ends of the feeding rotary shafts 32 and 33 and a retreat position p2 away from the support position p1 by the lifting cylinder 52 and the horizontal movement mechanism 54. is there. In addition, the control unit 26 of the material supply apparatus 2 is electrically connected to a drive source (for example, a servo motor or the like) of the elevating cylinder 52 and the horizontal movement mechanism 54, and controls the movement of the both 52 and 54. That is, in the material supply apparatus 2 of the present embodiment, the support unit 51 automatically moves between the support position p1 and the retracted position p2 according to control by the control unit 26. Therefore, the movement process of the support part 51 by a worker can be omitted, and the worker's work efficiency can be improved. However, the present invention is not limited to this, and the operator may manually move the support portion 51.
＜先行の資材５ａと後行の資材５ｂの接合処理＞
　図６は先行の資材５ａと後行の資材５ｂの接合処理のフロー図である。図７は支持ユニット５０の動作説明図である。資材供給装置２の制御部２６は、先行の資材コイル６ａの残量が規定値以下になると、先行の資材５ａを後行の資材コイル６ｂの外周面に押し付けて接合する。その前の状態では、図２に示すように、Ｘ方向上流側の繰り出し用回転軸３２に支持された先行の資材コイル６ａから繰り出される先行の資材５ａが加工装置３へ供給されている。一方、作業者はクレーン４０を用いてＸ方向下流側の繰り出し用回転軸３３に後行の資材コイル６ｂのセットを行う（Ｓ０１）。後行の資材コイル６ｂのセット時には、支持ユニット５０の支持部５１と後行の資材コイル６ｂとが接触しないように、支持部５１は退避位置ｐ２に位置している。 <Joint processing of preceding material 5a and following material 5b>
FIG. 6 is a flowchart of the joining process of the preceding material 5a and the succeeding material 5b. FIG. 7 is an explanatory view of the operation of the support unit 50. When the remaining amount of the preceding material coil 6a falls below a specified value, the control unit 26 of the material supply device 2 presses and joins the preceding material 5a to the outer peripheral surface of the succeeding material coil 6b. In the previous state, as shown in FIG. 2, the preceding material 5 a fed from the preceding material coil 6 a supported by the feeding rotary shaft 32 on the upstream side in the X direction is supplied to the processing device 3. On the other hand, the operator uses the crane 40 to set the succeeding material coil 6b on the feeding rotary shaft 33 on the downstream side in the X direction (S01). When the succeeding material coil 6b is set, the support portion 51 is positioned at the retracted position p2 so that the support portion 51 of the support unit 50 and the succeeding material coil 6b do not come into contact with each other.
　後行の資材コイル６ｂのセットが完了したことを、作業者が制御部２６に入力すると、制御部２６は、支持部５１を退避位置ｐ２から支持位置ｐ１へと移動させる（Ｓ０２）。具体的には、図７に示すように、先ず水平移動機構５４が支持部５１を繰り出し用回転軸３３の下方の位置までＸ方向の上流側に移動させる。次に、昇降用シリンダー５２が繰り出し用回転軸３３を支持する位置まで（詳しくは支持部５１がブラケット３９に当接するまで）支持部５１を上昇させる。 When the operator inputs to the control unit 26 that the succeeding material coil 6b has been set, the control unit 26 moves the support unit 51 from the retracted position p2 to the support position p1 (S02). Specifically, as shown in FIG. 7, first, the horizontal moving mechanism 54 moves the support portion 51 to the upstream side in the X direction to a position below the feeding rotary shaft 33. Next, the support portion 51 is raised to a position where the elevating cylinder 52 supports the feeding rotary shaft 33 (specifically, until the support portion 51 comes into contact with the bracket 39).
　次に、制御部２６は、後行の資材コイル６ｂを支持する繰り出し用回転軸、つまりＸ方向下流側の繰り出し用回転軸（図１では３３）を回転させ、後行の資材コイル６ｂの回転を開始する（Ｓ０３）。制御部２６は、後行の資材コイル６ｂの周速値が、先行の資材５ａの繰り出し速度値と等しくなるように、つまり加工装置３における資材５の搬送速度と等しくなるように、後行の資材コイル６ｂの周速を加速する。 Next, the control unit 26 rotates the feeding rotation shaft that supports the subsequent material coil 6b, that is, the feeding rotation shaft (33 in FIG. 1) on the downstream side in the X direction, and rotates the subsequent material coil 6b. Is started (S03). The control unit 26 determines that the peripheral speed value of the succeeding material coil 6b is equal to the feeding speed value of the preceding material 5a, that is, equal to the conveying speed of the material 5 in the processing apparatus 3. The peripheral speed of the material coil 6b is accelerated.
　次に、制御部２６は、後行の資材コイル６ｂの外周面に向けて先行の資材５ａの押し付け動作を行い、先行の資材５ａに後行の資材５ｂを接合する。そのために制御部２６は、後行の資材コイル６ｂの外周面のうちの先端部（つまり接合用の両面テープが設けられた部位）と接合ユニット２３のプレスロール２３ｄとが対向するタイミングにて、プレスロール２３ｄを退避位置から接合位置へと移動させる。そうして、後行の資材コイル６ｂから繰り出される後行の資材５ｂの加工装置３への供給が開始する（Ｓ０４）。 Next, the control unit 26 performs the pressing operation of the preceding material 5a toward the outer peripheral surface of the succeeding material coil 6b, and joins the succeeding material 5b to the preceding material 5a. For that purpose, the control unit 26, at the timing when the front end portion of the outer peripheral surface of the subsequent material coil 6b (that is, the portion provided with the double-sided tape for bonding) and the press roll 23d of the bonding unit 23 face each other. The press roll 23d is moved from the retracted position to the joining position. Then, the supply of the subsequent material 5b fed out from the subsequent material coil 6b to the processing device 3 starts (S04).
　次に、制御部２６は、プレスロール２３ｄを接合位置から退避位置へと移動させるとともに、切断ユニット２４のカッター刃２４ｃを退避位置から切断位置へと移動させ、先行の資材５ａを先行の資材コイル６ａの紙管から切り離す切断動作を行う。これにより先行の資材５ａの加工装置３への供給が停止する。よって制御部２６は先行の資材コイル６ａを支持する繰り出し用回転軸、つまりＸ方向上流側の繰り出し用回転軸（図１では３２）の回転を停止する（Ｓ０５）。 Next, the control unit 26 moves the press roll 23d from the joining position to the retracted position, and moves the cutter blade 24c of the cutting unit 24 from the retracted position to the cutting position, and moves the preceding material 5a to the preceding material coil. A cutting operation for separating from the paper tube 6a is performed. As a result, the supply of the preceding material 5a to the processing device 3 is stopped. Therefore, the control unit 26 stops the rotation of the feeding rotation shaft that supports the preceding material coil 6a, that is, the feeding rotation shaft (32 in FIG. 1) on the upstream side in the X direction (S05).
　そして、制御部２６は、プレスロール２３ｄによる押し付け動作が終了してから後行の資材コイル６ｂが１回転以上回転した後に、旋回部材３０を旋回する。そのために、制御部２６は支持部５１を支持位置ｐ１から退避位置ｐ２へと移動させる（Ｓ０６）。具体的には図７に示すように、先ず昇降用シリンダー５２が支持部５１を下方へ移動させる。次に水平移動機構５４が支持部５１を繰り出し用回転軸３３よりもＸ方向の下流側に移動させる。その後、制御部２６は旋回部材３０を時計回りに１８０度旋回する（Ｓ０７）。これにより後行の資材コイル６ｂは先行の資材コイル６ａが位置した場所に移動する。そして、作業者はＸ方向下流側の繰り出し用回転軸（３３と入れ替わった３２）に新しい次の資材コイル６のセットを行う（Ｓ０８）。資材供給装置２が加工装置３への資材供給を終了するまでの間、制御部２６は上記の処理を繰り返す。 Then, after the pressing operation by the press roll 23d is completed, the control unit 26 turns the turning member 30 after the succeeding material coil 6b rotates one or more times. For this purpose, the control unit 26 moves the support unit 51 from the support position p1 to the retracted position p2 (S06). Specifically, as shown in FIG. 7, first, the lifting cylinder 52 moves the support portion 51 downward. Next, the horizontal movement mechanism 54 moves the support portion 51 to the downstream side in the X direction from the feeding rotary shaft 33. Thereafter, the control unit 26 turns the turning member 30 clockwise by 180 degrees (S07). As a result, the succeeding material coil 6b moves to the place where the preceding material coil 6a is located. Then, the operator sets a new next material coil 6 on the feeding rotary shaft (32 replaced with 33) on the downstream side in the X direction (S08). Until the material supply device 2 finishes supplying the material to the processing device 3, the control unit 26 repeats the above processing.
　以上のように、本実施形態の資材供給装置２では、先行の資材コイル６ａの残量が少なくなると、一対の繰り出し用回転軸３２,３３のうちの一方の駆動により回転する後行の資材コイル６ｂの外周面に、他方の繰り出し用回転軸３２，３３の駆動により先行の資材コイル６ａから繰り出される先行の資材５ａの押し付け動作が行われ、先行の資材５ａに後行の資材５ｂが接合される。そのため、資材供給装置２から途切れることなく連続して加工装置３に資材５が供給され、加工装置３は停止することなく吸収性物品を製造できる。 As described above, in the material supply apparatus 2 of the present embodiment, when the remaining amount of the preceding material coil 6a decreases, the subsequent material coil that rotates by driving one of the pair of feeding rotation shafts 32 and 33 is used. A pressing operation of the preceding material 5a fed from the preceding material coil 6a is performed on the outer peripheral surface of 6b by driving the other feeding rotating shafts 32 and 33, and the succeeding material 5b is joined to the preceding material 5a. The Therefore, the material 5 is continuously supplied to the processing device 3 without interruption from the material supply device 2, and the processing device 3 can manufacture the absorbent article without stopping.
　また、吸収性物品を構成する資材数は多く、吸収性物品の製造装置１では、加工装置３に対して複数の資材供給装置２を配置することになる。図２に示すように複数の資材供給装置２と加工装置３を直角に配置する場合に、繰り出し用回転軸３２，３３を両持ち構造にすると、装置幅が広がり、資材供給装置２の配置が難しくなってしまう。また、装置構成が複雑化するためコストがかかってしまう。特に、本実施形態の資材供給装置２のように旋回部材３０により一対の繰り出し用回転軸３２，３３の位置が入れ替わる場合に両持ち構造にすると、より一層装置が大型化し、コストがかかってしまう。そのため、本実施形態の資材供給装置２では繰り出し用回転軸３２，３３が資材コイル６を片持ち状に支持する。 Further, the number of materials constituting the absorbent article is large, and in the absorbent article manufacturing apparatus 1, a plurality of material supply apparatuses 2 are arranged with respect to the processing apparatus 3. As shown in FIG. 2, when the plurality of material supply devices 2 and the processing device 3 are arranged at right angles, if the rotary shafts 32 and 33 for feeding are both supported, the width of the device is widened, and the arrangement of the material supply device 2 is increased. It will be difficult. In addition, the device configuration becomes complicated, and costs increase. In particular, when the position of the pair of feeding rotary shafts 32 and 33 is changed by the revolving member 30 as in the material supply device 2 of the present embodiment, if the double-supported structure is used, the device is further increased in size and costs are increased. . Therefore, in the material supply apparatus 2 of the present embodiment, the feeding rotary shafts 32 and 33 support the material coil 6 in a cantilever manner.
　但し、繰り出し用回転軸３２，３３が資材コイル６を常時片持ち状に支持すると、資材コイル６の重量が重い場合に、旋回部材３０に支持されていない側の繰出し用回転軸３２，３３の端部が下がってしまう。所謂前垂れ（片持ち梁のたわみ）が生じてしまう。 However, when the feeding rotating shafts 32 and 33 always support the material coil 6 in a cantilevered manner, when the weight of the material coil 6 is heavy, the feeding rotating shafts 32 and 33 on the side not supported by the swivel member 30 are used. The edge will go down. So-called front drooping (cantilever deflection) occurs.
　そこで、本実施形態の資材供給装置２は、後行の資材コイル６ｂ、つまり資材供給が未だなされていない重い資材コイル６ｂを支持する繰り出し用回転軸３２，３３の端部のうち旋回部材３０側とは反対側の端部を支持する支持部５１を備える。更に、支持部５１は、繰り出し用回転軸３２，３３の端部を支持する支持位置ｐ１と、支持位置ｐ１から離れた退避位置ｐ２との間を移動可能となっている。 Therefore, the material supply device 2 of the present embodiment is configured so that the end of the rotation shafts 32 and 33 for feeding that supports the subsequent material coil 6b, that is, the heavy material coil 6b that has not yet been supplied, is on the turning member 30 side. The support part 51 which supports the edge part on the opposite side is provided. Further, the support portion 51 is movable between a support position p1 that supports the ends of the feeding rotary shafts 32 and 33 and a retracted position p2 that is away from the support position p1.
　そのため、繰り出し用回転軸３２，３３を片持ち構造にして装置の小型化、低コスト化を図りつつ、旋回部材３０に支持されていない繰り出し用回転軸３２，３３の端部を支持部５１によって適宜支持できる。よって、繰り出し用回転軸３２，３３及び資材コイル６の前垂れを抑制できる。例えば、後行の資材コイル６ｂからの資材供給時に支持部５１が繰り出し用回転軸３２，３３を支持することで、繰り出し用回転軸３２，３３の前垂れによる資材５の蛇行や皺の発生等を抑えて資材５を供給できる。また、繰り出し用回転軸３２，３３の耐久性を高められる。 Therefore, the end portions of the feeding rotary shafts 32 and 33 that are not supported by the turning member 30 are supported by the support portion 51 while the feeding rotary shafts 32 and 33 are cantilevered to reduce the size and cost of the apparatus. It can be supported as appropriate. Therefore, forward drooping of the feeding rotary shafts 32 and 33 and the material coil 6 can be suppressed. For example, when the material is supplied from the succeeding material coil 6b, the support portion 51 supports the feeding rotary shafts 32 and 33, thereby causing the material 5 to meander or wrinkle due to the forward hanging of the feeding rotary shafts 32 and 33. The material 5 can be supplied while being suppressed. Further, the durability of the feeding rotary shafts 32 and 33 can be improved.
　そして、旋回部材３０の旋回時には、支持部５１は退避位置ｐ２に位置する。そのため、繰り出し用回転軸３２，３３と支持部５１とが接触することなく、繰り出し用回転軸３２，３３を旋回させることができる。換言すると、支持部５１を旋回部材３０とともに旋回させる必要がないため、装置構成を簡素化でき、装置の低コスト化を図れる。 And when the turning member 30 is turned, the support portion 51 is located at the retracted position p2. Therefore, the feeding rotary shafts 32 and 33 can be turned without contacting the feeding rotary shafts 32 and 33 and the support portion 51. In other words, since it is not necessary to turn the support portion 51 together with the turning member 30, the device configuration can be simplified and the cost of the device can be reduced.
　また、接合ユニット２３（プレスロール２３ｄ）による後行の資材コイル６ｂの外周面に向けての先行の資材５ａの押し付け動作時には、支持部５１が支持位置ｐ１に位置する。そのため、後行の資材コイル６ｂを支持する繰り出し用回転軸３２，３３の前垂れを抑制した状態で、先行の資材５ａと後行の資材５ｂを接合できる。よって、先行の資材５ａと後行の資材５ｂとを幅方向に亘って確実に接合できる。 Further, during the pressing operation of the preceding material 5a toward the outer peripheral surface of the succeeding material coil 6b by the joining unit 23 (press roll 23d), the support portion 51 is positioned at the support position p1. Therefore, the preceding material 5a and the succeeding material 5b can be joined in a state in which the forward sagging of the feeding rotary shafts 32 and 33 that support the succeeding material coil 6b is suppressed. Therefore, the preceding material 5a and the succeeding material 5b can be reliably joined across the width direction.
　また、本実施形態の資材供給装置２では、後行の資材コイル６ｂがセットされる繰り出し用回転軸３２，３３の位置と、接合ユニット２３による押し付け動作時に後行の資材コイル６ｂを支持する繰り出し用回転軸３２，３３の位置とが同じである。つまり、支持部５１が支持可能な位置に位置する繰り出し用回転軸３２，３３、本実施形態の場合はＸ方向下流側に位置する繰り出し用回転軸３２，３３に、後行の資材コイル６ｂがセットされる。 Further, in the material supply device 2 of the present embodiment, the positions of the feeding rotary shafts 32 and 33 where the succeeding material coil 6b is set and the feeding that supports the succeeding material coil 6b during the pressing operation by the joining unit 23. The positions of the rotary shafts 32 and 33 for use are the same. That is, the subsequent material coil 6b is placed on the feeding rotary shafts 32 and 33 positioned at a position where the support portion 51 can be supported, or in the case of this embodiment, on the feeding rotary shafts 32 and 33 located on the downstream side in the X direction. Set.
　仮にＸ方向上流側に位置する繰り出し用回転軸３２，３３に後行の資材コイル６ｂがセットされる場合、新品の重量の重い後行の資材コイル６ｂを、押し付け動作を行う位置に向けて旋回する必要がある。しかし、上記の場合にはその必要がないため、旋回部材３０の旋回動力を小さくでき、装置の低コスト化を図れる。更に上記の場合には、Ｘ方向上流側に位置する繰り出し用回転軸３２，３３が新品の重量の重い後行の資材コイル６ｂを支持することがない。そのため、Ｘ方向上流側に位置する繰り出し用回転軸３２，３３を支持する支持ユニットを設けなくてもよく、Ｘ方向下流側に位置する繰り出し用回転軸３２，３３を支持する支持ユニット５０を設けるだけでよい。よって、装置を簡素化でき、低コスト化を図れる。 If the succeeding material coil 6b is set on the feeding rotary shafts 32 and 33 positioned on the upstream side in the X direction, the succeeding material coil 6b having a new weight is turned toward the position where the pressing operation is performed. There is a need to. However, in the above case, this is not necessary, so that the turning power of the turning member 30 can be reduced, and the cost of the apparatus can be reduced. Furthermore, in the above case, the feeding rotary shafts 32 and 33 positioned on the upstream side in the X direction do not support the new material coil 6b having a heavy weight. Therefore, it is not necessary to provide a support unit for supporting the feeding rotary shafts 32 and 33 located on the upstream side in the X direction, and a support unit 50 for supporting the feeding rotary shafts 32 and 33 located on the downstream side in the X direction is provided. Just do it. Therefore, the apparatus can be simplified and the cost can be reduced.
　そして、後行の資材コイル６ｂのセット時には支持部５１が退避位置ｐ２に位置する。そのため、後行の資材コイル６ｂと支持部５１とが接触することなく、後行の資材コイル６ｂを繰り出し用回転軸３２，３３にセットできる。詳説すると、支持部５１に加えて昇降用シリンダー５２及び本体部５３も退避位置ｐ２に位置し、後行の資材コイル６ｂに接触しない配置となる。 And, when the succeeding material coil 6b is set, the support portion 51 is positioned at the retreat position p2. Therefore, the succeeding material coil 6b can be set on the feeding rotary shafts 32 and 33 without contacting the succeeding material coil 6b and the support portion 51. More specifically, in addition to the support portion 51, the lifting cylinder 52 and the main body portion 53 are also located at the retracted position p2 and are not in contact with the subsequent material coil 6b.
　但し上記に限らず、Ｘ方向上流側に位置する繰り出し用回転軸３２，３３に後行の資材コイル６ｂをセットしてもよい。その場合、後行の資材コイル６ｂのセット時に、後行の資材コイル６ｂと支持ユニット５０とが接触するおそれがない。この場合、繰り出し用回転軸３２，３３が支持ユニット５０に接触せずに旋回できればよいので、支持部５１がＸ方向に移動せずに昇降するだけの構成でもよい。 However, the present invention is not limited to the above, and the subsequent material coil 6b may be set on the feeding rotary shafts 32 and 33 located on the upstream side in the X direction. In that case, there is no possibility that the succeeding material coil 6b and the support unit 50 are in contact with each other when the succeeding material coil 6b is set. In this case, since it is sufficient that the feeding rotary shafts 32 and 33 can turn without contacting the support unit 50, the support unit 51 may be moved up and down without moving in the X direction.
　また、本実施形態の資材供給装置２では、後行の資材コイル６ｂが繰り出し用回転軸３２，３３にセットされてから当該繰り出し用回転軸３２，３３が回転するまでの間に、支持部５１が退避位置ｐ２から支持位置ｐ１へ移動する。つまり、後行の資材コイル６ｂがセットされた後、支持部５１が繰り出し用回転軸３２，３３を出来る限り早く支持する。そのため、繰り出し用回転軸３２，３３の前垂れをより一層抑制できる。また、新品の重量の重い後行の資材コイル６ｂを支持する繰り出し用回転軸３２，３３の回転中に支持部５１によって前垂れが抑制されるので、繰り出し用回転軸３２，３３の耐久性を高められる。 Further, in the material supply apparatus 2 of the present embodiment, the support portion 51 is provided after the subsequent material coil 6b is set on the feeding rotary shafts 32 and 33 until the feeding rotary shafts 32 and 33 rotate. Moves from the retracted position p2 to the support position p1. That is, after the succeeding material coil 6b is set, the support portion 51 supports the feeding rotary shafts 32 and 33 as soon as possible. Therefore, it is possible to further suppress the forward sagging of the feeding rotating shafts 32 and 33. Further, since the front hanging is suppressed by the support portion 51 during the rotation of the feeding rotary shafts 32 and 33 that support the new and heavy material coil 6b, the durability of the feeding rotary shafts 32 and 33 is improved. It is done.
　また、接合ユニット２３による押し付け動作が終了してから、後行の資材コイル６ｂを支持する繰り出し用回転軸３２，３３が少なくとも１回転した後に、旋回部材３０が旋回する。そのため、後行の資材５ｂの搬送が安定した状態で、後行の資材コイル６ｂを旋回できる。よって、旋回時にも安定して加工装置３に資材５を供給できる。また、後行の資材コイル６ｂが消費されて軽くなった状態で旋回部材３０等を旋回できる。よって、旋回部材３０の旋回動力を小さくでき、装置の低コスト化を図れる。 Further, after the pressing operation by the joining unit 23 is completed, the turning member 30 is turned after the feeding rotary shafts 32 and 33 for supporting the succeeding material coil 6b have made at least one turn. Therefore, the succeeding material coil 6b can be turned in a state where the transport of the succeeding material 5b is stable. Therefore, the material 5 can be stably supplied to the processing apparatus 3 even when turning. Further, the swivel member 30 and the like can be swung while the subsequent material coil 6b is consumed and lightened. Therefore, the turning power of the turning member 30 can be reduced, and the cost of the apparatus can be reduced.
　更に好ましくは、旋回部材３０が旋回する直前まで、後行の資材コイル６ｂを支持する繰り出し用回転軸３２，３３を支持部５１が支持するようにするとよい。そうすることで、供給開始時の重い後行の資材コイル６ｂを支持する繰り出し用回転軸３２，３３の前垂れを抑制でき、資材５の蛇行や皺の発生等を抑えて資材５を供給できる。 More preferably, the support portion 51 may support the feeding rotary shafts 32 and 33 that support the succeeding material coil 6b until immediately before the turning member 30 turns. By doing so, it is possible to suppress the drooping of the feeding rotary shafts 32 and 33 that support the heavy subsequent material coil 6b at the start of the supply, and it is possible to supply the material 5 while suppressing the meandering of the material 5 and the occurrence of wrinkles.
　また、支持部５１が退避位置ｐ２から支持位置ｐ１へ移動する際に、支持部５１が水平移動機構５４により繰り出し用回転軸３２，３３の下方まで位置した後、支持部５１は昇降用シリンダー５２により繰り出し用回転軸３２，３３の下方から上昇して繰り出し用回転軸３２，３３を支持する。そのため、支持部５１が退避位置ｐ２に位置している間に繰り出し用回転軸３２，３３に前垂れが生じた場合でも、支持部５１が下方から繰り出し用回転軸３２，３３の端部をスムーズに支持できる。また、支持部５１の上昇によって、繰り出し用回転軸３２，３３の前垂れを修正でき、資材５の蛇行や皺の発生等を抑えて資材５を供給できる。 Further, when the support portion 51 moves from the retracted position p2 to the support position p1, the support portion 51 is positioned below the feeding rotary shafts 32 and 33 by the horizontal movement mechanism 54, and then the support portion 51 is moved up and down the cylinder 52. As a result, the feeding rotary shafts 32 and 33 are lifted from below and support the feeding rotary shafts 32 and 33. Therefore, even if the forward rotation shafts 32 and 33 are drooped while the support portion 51 is at the retracted position p2, the support portion 51 smoothly moves the ends of the feed rotation shafts 32 and 33 from below. I can support it. Further, by raising the support portion 51, it is possible to correct the drooping of the feeding rotary shafts 32 and 33, and it is possible to supply the material 5 while suppressing the meandering of the material 5 and the occurrence of wrinkles.
＝＝＝第２実施形態＝＝＝
　図８は第２実施形態における資材供給装置２の概略正面図である。第２実施形態の資材供給装置２は、一対の繰り出し用回転軸３２,３３のうち支持部５１が支持する繰り出し用回転軸、つまりＸ方向下流側に位置する繰り出し用回転軸（図８では３３）とは異なる繰り出し用回転軸、つまりＸ方向上流側に位置する繰り出し用回転軸（図８では３２）を支持する別の支持ユニット６０を有する。なお、別の支持ユニット６０の構成は支持ユニット５０の構成と同じとし、別の支持ユニット６０も、支持部６１と、昇降用シリンダー６２と、本体部６３と、水平移動機構６４とを有する。 === Second Embodiment ===
FIG. 8 is a schematic front view of the material supply apparatus 2 according to the second embodiment. The material supply apparatus 2 according to the second embodiment includes a feeding rotary shaft supported by the support portion 51 of the pair of feeding rotary shafts 32 and 33, that is, a feeding rotary shaft located on the downstream side in the X direction (33 in FIG. 8). ), Ie, another feeding unit 60 that supports the feeding rotary shaft (32 in FIG. 8) located on the upstream side in the X direction. The configuration of another support unit 60 is the same as the configuration of the support unit 50, and the other support unit 60 also includes a support portion 61, a lifting cylinder 62, a main body portion 63, and a horizontal movement mechanism 64.
　そのため、第２実施形態の資材供給装置２では、後行の資材コイル６ｂが旋回した後も、後行の資材コイル６ｂを支持する繰り出し用回転軸３２，３３が別の支持ユニット６０の支持部６１で支持される。よって、Ｘ方向の上流側に移動した後行の資材コイル６ｂを支持する繰り出し用回転軸３２，３３の前垂れを抑制でき、後行の資材コイル６ｂから供給される資材５の蛇行や皺の発生等を抑えられる。 Therefore, in the material supply device 2 of the second embodiment, even after the succeeding material coil 6b turns, the feeding rotary shafts 32 and 33 that support the succeeding material coil 6b are the support portions of the separate support unit 60. 61 is supported. Therefore, it is possible to suppress the forward drooping of the feeding rotary shafts 32 and 33 that support the subsequent material coil 6b that has moved to the upstream side in the X direction, and the meandering or wrinkling of the material 5 supplied from the subsequent material coil 6b occurs. Etc. can be suppressed.
　また、Ｘ方向上流側に位置する繰り出し用回転軸３２，３３に後行の資材コイル６ｂをセットする場合に、後行の資材コイル６ｂがセットされてから旋回されるまでの間、新品の重量の重い後行の資材コイル６ｂを支持する繰り出し用回転軸３２，３３を別の支持ユニット６０で支持できる。よって、後行の資材コイル６ｂを支持する繰り出し用回転軸３２，３３の前垂れを抑制できる。 Further, when the succeeding material coil 6b is set on the feeding rotary shafts 32 and 33 located on the upstream side in the X direction, the weight of the new article is not changed from when the succeeding material coil 6b is set until turning.
