Description

スプライス装置および方法Splicing equipment and method
　本発明は（原反）ウェブのスプライス装置および方法に関する。 The present invention relates to a (raw) web splicing device and method.
　原反ウェブを連続的に加工ラインに供給するために、旧原反ウェブの終端部に新原反の始端部を重ね合わせて接合する、スプライスが行なわれる（特許文献１）。 In order to continuously supply the raw web to the processing line, a splice is performed in which the starting end of the new web is overlapped and joined to the terminal end of the old web (Patent Document 1).
一方、非伸縮性のウェブに伸縮性を発現させるために、一対のギヤ状の延伸加工機にウェブを挟んで延伸させる場合がある（特許文献２）。この場合に、両ウェブが重なる継ぎ部がウェブの幅方向に平行に延びていると、継ぎ部の境目が破断することがある。 On the other hand, in order to make a non-stretchable web stretchable, the web may be stretched between a pair of gear-shaped stretching machines (Patent Document 2). In this case, if the joint portion where both webs overlap extends parallel to the width direction of the webs, the boundary between the joint portions may break.

テンション制御部４０は、スプライス部３０の下流側でガイドローラを介して設けられ、走行するウェブのテンションを制御するテンションローラ４１と、一端部にテンションローラ４１が取り付けられた回動アーム４２とを有する。テンション制御部４０は、揺動することによって、走行する第１および第２ウェブ１１Ｌ，１１Ｒのテンションを一定にする。 The tension control unit 40 is provided downstream of the splice unit 30 via a guide roller, and includes a tension roller 41 that controls the tension of the running web, and a rotating arm 42 that has the tension roller 41 attached to one end. have The tension control unit 40 keeps the tension of the running first and second webs 11L and 11R constant by swinging.
蓄積部５０は、テンション制御部４０の下流側に設けられている。蓄積部５０は、複数の固定ローラ５１と、固定ローラ５１に対して近接離間する複数の可動ローラ５２と、可動ローラ５２を移動させる駆動機構５３とから構成されている。固定ローラ５１は、略一列に並んで配設されている。可動ローラ５２は、固定ローラ５１から離間して設けられている。可動ローラ５２は、エアシリンダ機構で構成された駆動機構５３によって固定ローラ５１に近接離間する方向に揺動する。蓄積部５０は、使用中のウェブが固定ローラ５１と可動ローラ５２に交互に巻き掛けられている。 The storage section 50 is provided downstream of the tension control section 40. The storage unit 50 includes a plurality of fixed rollers 51, a plurality of movable rollers 52 that move close to and away from the fixed roller 51, and a drive mechanism 53 that moves the movable rollers 52. The fixed rollers 51 are arranged substantially in a line. The movable roller 52 is provided apart from the fixed roller 51. The movable roller 52 swings toward and away from the fixed roller 51 by a drive mechanism 53 configured with an air cylinder mechanism. In the storage section 50, the web in use is alternately wound around a fixed roller 51 and a movable roller 52.
蓄積部５０は、第１の巻回部１２Ｌ、第２の巻回部１２Ｒの一方からウェブが供給されているとき、可動ローラ５２が固定ローラ５１から離間する方向に移動しており、走行する第１ウェブ１１Ｌ又は第２ウェブ１１Ｒを蓄積する。一方、切断部２０が第１ウェブ１１Ｌ、第２ウェブ１１Ｒの何れかを切断しスプライス中であるとき、すなわち下流側のラインにウェブが供給されていないとき、可動ローラ５２が固定ローラ５１に近接する方向に移動し、下流のラインに、図示しない駆動手段によってウェブを供給する。 When the web is being supplied from one of the first winding part 12L and the second winding part 12R, the storage part 50 moves in a direction in which the movable roller 52 moves away from the fixed roller 51 and runs. The first web 11L or the second web 11R is accumulated. On the other hand, when the cutting section 20 is cutting and splicing either the first web 11L or the second web 11R, that is, when no web is being supplied to the downstream line, the movable roller 52 approaches the fixed roller 51. The web is fed to the downstream line by a driving means (not shown).
 上述のような構成をしたスプライス装置１０を用いた第１および第２ウェブ１１Ｌ，１１Ｒを連続的に送給できるようにするスプライス方法について説明する。なお、ここでは、説明の便宜上、第１ウェブ１１Ｌが使用されており、予備のウェブである第２ウェブ１１Ｒを第１ウェブ１１Ｌに接合する場合について説明する。 A splicing method that uses the splicing device 10 configured as described above to continuously feed the first and second webs 11L and 11R will be described. Here, for convenience of explanation, the first web 11L is used, and a case will be described in which the second web 11R, which is a spare web, is joined to the first web 11L.
 通常運転中、第１ウェブ１１Ｌは、駆動ローラ１５Ｌ、テンション制御部４０により、第１ウェブ１１Ｌの張力や走行速度が制御されながら、経路に沿って蓄積部５０の下流側の製造（加工）ラインに送給される。このとき、切断部２０の第１および第２カッタ２１Ｌ，２１Ｒや第１パッド３１Ｌは、パスラインの第１および第２ウェブ１１Ｌ，１１Ｒから離間している。また、蓄積部５０は、可動ローラ５２が固定ローラ５１から最も離間した状態で、使用中の第１ウェブ１１Ｌを蓄積した状態にある。さらに、第２ウェブ１１Ｒは、その始端部が第２パッド３１Ｒにより吸引保持されている。 During normal operation, the first web 11L is moved along the production (processing) line downstream of the storage section 50 along the route while the tension and running speed of the first web 11L are controlled by the drive roller 15L and the tension control section 40. will be sent to At this time, the first and second cutters 21L and 21R of the cutting section 20 and the first pad 31L are spaced apart from the first and second webs 11L and 11R of the pass line. Further, the storage unit 50 is in a state where the movable roller 52 is the most distant from the fixed roller 51, and the first web 11L in use is stored. Furthermore, the starting end of the second web 11R is suction-held by the second pad 31R.
次に、残量検出部１４Ｌが第１ウェブ１１Ｌの残量が所定量以下になったことを検出すると、第１の巻回部１２Ｌと左側の駆動ローラ１５Ｌは、第１ウェブ１１Ｌの走行を停止する。第１の巻回部１２Ｌからの第１ウェブ１１Ｌの供給を停止した状態にあるとき、蓄積部５０は、可動ローラ５２を固定ローラ５１に近接する方向に移動させ、巻回されているウェブを緩め下流側にウェブを供給し続ける。 Next, when the remaining amount detection section 14L detects that the remaining amount of the first web 11L has become less than a predetermined amount, the first winding section 12L and the left drive roller 15L stop the first web 11L from running. Stop. When the supply of the first web 11L from the first winding section 12L is stopped, the storage section 50 moves the movable roller 52 in a direction approaching the fixed roller 51 to remove the wound web. Continue to feed the web to the downstream side.
一方、スプライス部３０の第１パッド３１Ｌは、走行が停止している第１ウェブ１１Ｌを吸引保持する。そして、切断部２０の第１カッタ２１Ｌは、図１１Ａに示すように、第１パッド３１Ｌによって保持された第１ウェブ１１Ｌに接近する方向に移動し、第１ウェブ１１Ｌを切断する。切断された第１ウェブ１１Ｌを保持した第１パッド３１Ｌと、第２ウェブ１１Ｒを保持した第２パッド３１Ｒとは、図１１Ｂに示すように、互いに接近する方向に移動し、第１ウェブ１１Ｌに予備の第２ウェブ１１Ｒの始端部を、接着テープを介して接合する。 On the other hand, the first pad 31L of the splice portion 30 attracts and holds the first web 11L, which is not running. Then, the first cutter 21L of the cutting section 20 moves in a direction approaching the first web 11L held by the first pad 31L, and cuts the first web 11L, as shown in FIG. 11A. As shown in FIG. 11B, the first pad 31L holding the cut first web 11L and the second pad 31R holding the second web 11R move toward each other and touch the first web 11L. The starting end of the spare second web 11R is joined via an adhesive tape.
その後、第２ウェブ１１Ｒへのスプライスが完了すると、図１０の右側の駆動ローラ１５Ｒは、第２ウェブ１１Ｒの搬送を開始する。また、蓄積部５０は、可動ローラ５２を固定ローラ５１から離間する方向に移動し第２ウェブ１１Ｒの蓄積を開始する。 Thereafter, when splicing to the second web 11R is completed, the drive roller 15R on the right side in FIG. 10 starts conveying the second web 11R. Further, the accumulation section 50 moves the movable roller 52 in a direction away from the fixed roller 51 and starts accumulating the second web 11R.
かかる従来のスプライス装置および方法では、図１０から把握できるように、第１パッド３１Ｌで吸着する前の第１ウェブ１１Ｌが第１パッド３１Ｌの吸着面に対し傾斜した非平行の状態となる。そのため、第１パッド３１Ｌで第１ウェブ１１Ｌを吸着する際に、第１ウェブ１１Ｌにシワが生じ易い。 In such a conventional splicing device and method, as can be understood from FIG. 10, the first web 11L before being attracted by the first pad 31L is in a non-parallel state that is inclined with respect to the attraction surface of the first pad 31L. Therefore, when the first pad 31L adsorbs the first web 11L, wrinkles are likely to occur in the first web 11L.
つぎに、本発明の一実施形態を図面にしたがって説明する。図１～図９Ａは同実施形態を示す。 Next, one embodiment of the present invention will be described according to the drawings. 1 to 9A show the same embodiment.

図１の第１または第２受け部２２Ｌ，２２Ｒの一方に対し、第１または第２カバー２３Ｌ，２３Ｒの一方が対面して第１または第２ユニットＵ１，Ｕ２の一方が閉じた状態と、図６の第１または第２受け部２２Ｌ，２２Ｒの他方に対し、第１または第２カバー２３Ｌ，２３Ｒの他方が離れて第１または第２ユニットＵ１，Ｕ２の他方が開いた状態とに設定することができるように構成されている。 A state in which one of the first or second covers 23L, 23R faces one of the first or second receiving parts 22L, 22R in FIG. 1, and one of the first or second units U1, U2 is closed; The other of the first or second covers 23L, 23R is separated from the other of the first or second receiving parts 22L, 22R in FIG. 6, and the other of the first or second units U1, U2 is set in an open state. It is configured so that it can be
また、図３～図５および図７Ａに示すように、第１および第２受け部２２Ｌ，２２Ｒに対し、それぞれ、第１および第２カバー２３Ｌ，２３Ｒが対面した状態となるように設定することができるように構成されている。 Further, as shown in FIGS. 3 to 5 and 7A, the first and second covers 23L and 23R may be set to face the first and second receiving portions 22L and 22R, respectively. It is configured so that it can be done.
図１において、固定フレーム１は第１受け部２２Ｌおよび第２受け部２２Ｒを固定した状態で支持する。第１回動フレーム２Ｌは、第１供給ロール５Ｌ、第１カバー２３Ｌ、第１カッタ２１Ｌおよび第１パッド３１Ｌを支持する。第２回動フレーム２Ｒは、第２供給ロール５Ｒ、第２カバー２３Ｒ、第２カッタ２１Ｒおよび第２パッド３１Ｒを支持する。 In FIG. 1, the fixed frame 1 supports the first receiving part 22L and the second receiving part 22R in a fixed state. The first rotation frame 2L supports the first supply roll 5L, the first cover 23L, the first cutter 21L, and the first pad 31L. The second rotating frame 2R supports the second supply roll 5R, second cover 23R, second cutter 21R, and second pad 31R.
図６に示すように、第１供給ロール５Ｌが第２供給ロール５Ｒから離れ、かつ、第１回動フレーム２Ｌが開くように第１ヒンジ３Ｌを中心に第１回動フレーム２Ｌを第１アクチュエータ４Ｌが回転させる。
一方、図１に示すように、第２供給ロール５Ｒが第１供給ロール５Ｌから離れ、かつ、第２回動フレーム２Ｒが開くように第２ヒンジ３Ｒを中心に第２回動フレーム２Ｒを第２アクチュエータ４Ｒが回転させる。 As shown in FIG. 6, the first rotation frame 2L is moved around the first hinge 3L by the first actuator so that the first supply roll 5L is separated from the second supply roll 5R and the first rotation frame 2L is opened. 4L rotates.
On the other hand, as shown in FIG. 1, the second rotation frame 2R is rotated around the second hinge 3R so that the second supply roll 5R is separated from the first supply roll 5L and the second rotation frame 2R is opened. 2 actuator 4R rotates.
本スプライス装置１０は、図１の第１供給ロール５Ｌから排出ロール６に沿って第１ウェブ１１Ｌが搬送される第１パスライン１Ｌと、図６の第２供給ロール５Ｒから前記排出ロール６に沿って第２ウェブ１１Ｒが搬送される第２パスライン１Ｒとを備える。 The present splicing apparatus 10 includes a first pass line 1L in which the first web 11L is conveyed from the first supply roll 5L in FIG. It includes a second pass line 1R along which the second web 11R is conveyed.
図２に示すように、第１カッタ２１Ｌは第１パスライン１Ｌ上の前記第１ウェブ１１Ｌの幅方向に斜めに横断するように延びる。また、図示していないが、第２カッタ２１Ｒも第２パスライン１Ｒ上の第２ウェブ１１Ｒの幅方向に斜めに横断するように延びる。なお、第１カッタ２１Ｌと第２カッタ２１Ｒとは、互いに同じ方向に傾斜している。 As shown in FIG. 2, the first cutter 21L extends obliquely across the width direction of the first web 11L on the first pass line 1L. Although not shown, the second cutter 21R also extends obliquely across the width direction of the second web 11R on the second pass line 1R. Note that the first cutter 21L and the second cutter 21R are inclined in the same direction.
図２において、第１パッド３１Ｌは第１カッタ２１Ｌの下流において、第１カッタ２１Ｌに沿って平行に斜めに延び、図７Ｂの第１ウェブ１１Ｌの終端部Ｅを吸着して保持する。同様に、図示していないが、第２パッド３１Ｒも第２カッタ２１Ｒの下流において、第２カッタ２１Ｒに沿って平行に斜めに延び、図７Ａの第２ウェブ１１Ｒの始端部Ｓを保持し、図７Ｂのように、第１パッド３１Ｌとの間で前記両ウェブを挟んで接合する。なお、第１パッド３１Ｌと第２パッド３１Ｒとは互いに合掌することができるように同じ方向に同じ角度傾斜で対面している。 In FIG. 2, the first pad 31L extends obliquely and parallel to the first cutter 21L downstream of the first cutter 21L, and attracts and holds the terminal end E of the first web 11L in FIG. 7B. Similarly, although not shown, the second pad 31R also extends obliquely and parallel to the second cutter 21R downstream of the second cutter 21R, and holds the starting end S of the second web 11R in FIG. 7A. As shown in FIG. 7B, both webs are sandwiched and joined to the first pad 31L. Note that the first pad 31L and the second pad 31R face each other in the same direction and at the same angle so that they can put their palms together.
図７Ｂにおいて、第１受け部２２Ｌは第１カッタ２１Ｌが第１ウェブ１１Ｌを切断する際に第１カッタ２１Ｌの刃を受ける。一方、図７Ｃにおいて、第２受け部２２Ｒは第２カッタ２１Ｒが第２ウェブ１１Ｒを切断する際に前記第２カッタ２１Ｒの刃を受ける。 In FIG. 7B, the first receiving portion 22L receives the blade of the first cutter 21L when the first cutter 21L cuts the first web 11L. On the other hand, in FIG. 7C, the second receiving portion 22R receives the blade of the second cutter 21R when the second cutter 21R cuts the second web 11R.
図７Ａの第１受け部２２Ｌと第１カッタ２１Ｌとの間には第１パスライン１Ｌが設定されている。一方、第２受け部２２Ｒと第２カッタ２１Ｒとの間には第２パスライン１Ｒが設定されている。 A first pass line 1L is set between the first receiving portion 22L and the first cutter 21L in FIG. 7A. On the other hand, a second pass line 1R is set between the second receiving portion 22R and the second cutter 21R.
図７Ａにおいて、第１カバー２３Ｌは第１カッタ２１Ｌが第１ウェブ１１Ｌの非切断位置Ｐに退避した状態で第１ウェブ１１Ｌが第１カッタ２１Ｌに接触するのを防止する。同様に、第２カバー２３Ｒは第２カッタ２１Ｒが第２ウェブ１１Ｒの非切断位置Ｐに退避した状態で第２ウェブ１１Ｒが第２カッタ２１Ｒに接触するのを防止する。 In FIG. 7A, the first cover 23L prevents the first web 11L from contacting the first cutter 21L when the first cutter 21L is retracted to the non-cutting position P of the first web 11L. Similarly, the second cover 23R prevents the second web 11R from contacting the second cutter 21R when the second cutter 21R is retracted to the non-cutting position P of the second web 11R.
本例の場合、第１カバー２３Ｌと第１受け部２２Ｌとの間を第１ウェブ１１Ｌが通過するように第１パスライン１Ｌが形成されている。一方、第２カバー２３Ｒと第２受け部２２Ｒとの間を第２ウェブ１１Ｒが通過するように第２パスライン１Ｒが形成されている。 In the case of this example, the first pass line 1L is formed such that the first web 11L passes between the first cover 23L and the first receiving portion 22L. On the other hand, a second pass line 1R is formed such that the second web 11R passes between the second cover 23R and the second receiving portion 22R.
本スプライス装置１０は、図１の第１ウェブ１１Ｌが通る第１パスライン１Ｌと図６の第２ウェブ１１Ｒが通る第２パスライン１Ｒとが互いに平行（図７Ａ参照）となるように排出ロール６の位置を変位させることができるように構成されている変位装置６０を備える。本例の場合、第１パスライン１Ｌおよび第２パスライン１Ｒは、共に鉛直面に沿って互いに平行に設定されている。 The present splicing device 10 is configured so that the discharge roll is arranged so that the first pass line 1L along which the first web 11L in FIG. 1 passes and the second pass line 1R along which the second web 11R in FIG. 6 passes are parallel to each other (see FIG. 7A). A displacement device 60 is provided, which is configured to be able to displace six positions. In this example, the first pass line 1L and the second pass line 1R are both set parallel to each other along a vertical plane.
図１の変位装置６０は例えば流体圧シリンダで構成され、排出ロール６を図１の第１のロール位置Ｐ１と図６の第２のロール位置Ｐ２とに選択的に配置できる。図１の排出ロール６が第１のロール位置Ｐ１にある場合、第１ウェブ１１Ｌは１つの鉛直面に沿った第１パスライン１Ｌを通る。一方、図６の排出ロール６が第２のロール位置Ｐ２にある場合、第２ウェブ１１Ｒは別の鉛直面に沿った第２パスライン１Ｒを通る。 The displacement device 60 in FIG. 1 is constituted by, for example, a hydraulic cylinder, and can selectively arrange the discharge roll 6 in a first roll position P1 in FIG. 1 and a second roll position P2 in FIG. 6. When the discharge roll 6 in FIG. 1 is in the first roll position P1, the first web 11L passes along the first pass line 1L along one vertical plane. On the other hand, when the discharge roll 6 in FIG. 6 is at the second roll position P2, the second web 11R passes along a second pass line 1R along another vertical plane.
このように、排出ロール６の位置が変位されるので、図７Ａのように、第１ウェブ１１Ｌを第１パッド３１Ｌで吸着する以前（ウェブの搬送中）においても、また、図７Ｂおよび図７Ｃのように各ウェブが両パッドで挟まれている場合においても各ウェブに対し各パッドの吸着面３１ｆは平行である。 Since the position of the discharge roll 6 is displaced in this way, as shown in FIG. 7A, even before the first web 11L is sucked by the first pad 31L (during conveyance of the web), as shown in FIGS. 7B and 7C, Even in the case where each web is sandwiched between both pads, the adsorption surface 31f of each pad is parallel to each web.
すなわち、各パッドの吸着面３１ｆが各ウェブを吸着する直前から吸着した瞬間に至るまで、各パッドとこれに対面する各吸着面３１ｆは平行である。したがって、吸着時にウェブに皺などが生じにくい。
たとえば、図１の第１ウェブ１１Ｌは第１供給ロール５Ｌから第１パッド３１Ｌに至るまで、第１パッド３１Ｌの吸着面３１ｆ（図７Ａ）に平行な面に沿って延びている。したがって、第１パッド３１Ｌが第１ウェブ１１Ｌを吸着する際に第１ウェブ１１Ｌに皺などが生じにくい。 That is, from just before the suction surface 31f of each pad suctions each web to the moment when the suction surface 31f of each pad suctions the web, each pad and each suction surface 31f facing the same are parallel to each other. Therefore, wrinkles are less likely to occur in the web during suction.
For example, the first web 11L in FIG. 1 extends from the first supply roll 5L to the first pad 31L along a plane parallel to the suction surface 31f (FIG. 7A) of the first pad 31L. Therefore, when the first pad 31L adsorbs the first web 11L, wrinkles are less likely to occur in the first web 11L.
本例のように、図７Ａおよび図７Ｂに示す第１カッタ２１Ｌおよび第２カッタ２１Ｒは、共にメインの刃２１Ｍおよびサブの刃２１Ｓを有していてもよい。各刃２１Ｍおよび２１Ｓは、第１または第２カバー２３Ｌ，２３Ｒの貫通孔２３Ｏを通って、第１または第２受け部２２Ｌ，２２Ｒの貫通孔２２Ｏに達するまで突出する。 As in this example, the first cutter 21L and the second cutter 21R shown in FIGS. 7A and 7B may both have a main blade 21M and a sub blade 21S. Each of the blades 21M and 21S protrudes through the through hole 23O of the first or second cover 23L, 23R until it reaches the through hole 22O of the first or second receiving portion 22L, 22R.
図１の排出ロール６の下流には前述の公知例の蓄積部５０と同様の蓄積部（図示せず）が設けられていてもよい。また、当該蓄積部の下流の加工ラインには、第１ウェブ１１Ｌおよび／または第２ウェブ１１Ｒに延伸加工を施す図８Ａおよび図８Ｂに示す周知の延伸加工装置７が設けられていてもよい。 A storage section (not shown) similar to the storage section 50 of the above-mentioned known example may be provided downstream of the discharge roll 6 in FIG. 1. Further, a processing line downstream of the storage section may be provided with a well-known stretching device 7 shown in FIGS. 8A and 8B that performs stretching on the first web 11L and/or the second web 11R.
つぎに、図９Ａおよび図９Ｂのように、先行のウェブ１１Ｌの終端部Ｅに待機中のウェブ１１Ｒの始端部Ｓを重ね合わせてウェブ同士を継ぐスプライス方法について説明する。 Next, as shown in FIGS. 9A and 9B, a splicing method will be described in which the starting end S of the waiting web 11R is overlapped with the terminal end E of the preceding web 11L to join the webs together.
ウェブの継ぎ、つまりスプライスは図１の第１供給ロール５Ｌから排出ロール６に沿った第１パスライン１Ｌを第１ウェブ１１Ｌが搬送される第１搬送工程と、図６の第２供給ロール５Ｒから排出ロール６に沿った第２パスライン１Ｒを第２ウェブ１１Ｒが搬送される第２搬送工程との間において行われる。 The joining of the web, that is, the splice, is performed in a first conveyance process in which the first web 11L is conveyed from the first supply roll 5L in FIG. This is performed between the second conveyance step in which the second web 11R is conveyed along the second pass line 1R along the discharge roll 6.
以下、ウェブの継ぎについて、図１の第１ウェブ１１Ｌの搬送後に第２ウェブ１１Ｒを継ぐ場合を代表して説明する。 Hereinafter, web splicing will be described as a representative case in which the second web 11R is spliced after the first web 11L in FIG. 1 is conveyed.
図９Ａの第１ウェブ１１Ｌを第２ウェブ１１Ｒに継ぐためには、第１パスライン１Ｌ（図１）上の第１ウェブ１１Ｌの終端を第１ウェブ１１Ｌの幅方向に斜めに横断するように切断する第１切断工程と、第２パスライン１Ｒ（図６）上の第２ウェブ１１Ｒの始端を第２ウェブ１１Ｒの幅方向に斜めに横断するように切断する第２切断工程とが実行される。図７Ｂにおいて、前記第１切断工程に先立って第１パスライン１Ｌ上の第１ウェブ１１Ｌの終端部Ｅを第１パッド３１Ｌが吸着保持する。 In order to join the first web 11L in FIG. 9A to the second web 11R, the end of the first web 11L on the first pass line 1L (FIG. 1) is diagonally crossed in the width direction of the first web 11L. A first cutting step of cutting the second web 11R and a second cutting step of cutting the starting end of the second web 11R on the second pass line 1R (FIG. 6) diagonally across the width direction of the second web 11R are performed. Ru. In FIG. 7B, prior to the first cutting step, the first pad 31L suction-holds the end portion E of the first web 11L on the first pass line 1L.
　本例では以下のようにウェブの継ぎを行う。
　図１の第１搬送工程において第１ウェブ１１Ｌが第１パスライン１Ｌで搬送されている状態で、図１のように第２ユニットＵ２を開く。当該開いた第２ユニットＵ２において、第２ウェブ１１Ｒの始端部Ｓ（図７Ａ）を第２パッド３１Ｒに吸着保持させる保持工程を実行する。前記始端部Ｓには第１ウェブ１１Ｌと対面する側に接着テープが設けられている。
　その後、図３のように、第２ユニットＵ２を閉じる。
　その後、搬送中の第１ウェブ１１Ｌの残量が所定量よりも少なくなった時点で、第１パスライン１Ｌにおける第１ウェブ１１Ｌの移動（搬送）を止める。この際、前記蓄積部５０に蓄積されたウェブを放出する。
　その後、図７Ａの第１パッド３１Ｌにより第１ウェブ１１Ｌを吸着保持し、図７Ａの第１カッタ２１Ｌにより第１ウェブ１１Ｌを切断する。
　第１ウェブ１１Ｌの切断後、図７Ｂの第１ウェブ１１Ｌの終端部Ｅと第２ウェブ１１Ｒの始端部Ｓとを第１パッド３１Ｌと第２パッド３１Ｒとの間で挟んで終端部Ｅと始端部Ｓとを重ね合わせる第１の重ね合わせ工程と、始端部Ｓと終端部Ｅとを接合して第１ウェブ１１Ｌに第２ウェブ１１Ｒを継ぐ第１の継ぎ工程とを行う。具体的に、第１の重ね合わせ工程および第１の継ぎ工程は以下のように実行する。 In this example, the web is spliced as follows.
The second unit U2 is opened as shown in FIG. 1 while the first web 11L is being transported along the first pass line 1L in the first transport process shown in FIG. In the opened second unit U2, a holding step is performed in which the starting end S (FIG. 7A) of the second web 11R is sucked and held by the second pad 31R. An adhesive tape is provided on the starting end S on the side facing the first web 11L.
Then, as shown in FIG. 3, the second unit U2 is closed.
Thereafter, when the remaining amount of the first web 11L being conveyed becomes less than a predetermined amount, the movement (conveyance) of the first web 11L on the first pass line 1L is stopped. At this time, the web accumulated in the accumulation section 50 is released.
Thereafter, the first web 11L is suctioned and held by the first pad 31L in FIG. 7A, and the first web 11L is cut by the first cutter 21L in FIG. 7A.
After cutting the first web 11L, the terminal end E of the first web 11L and the starting end S of the second web 11R in FIG. 7B are sandwiched between the first pad 31L and the second pad 31R, and the terminal end E and the starting end are A first overlapping process of overlapping the parts S and a first joining process of joining the starting end S and the terminal end E and joining the second web 11R to the first web 11L are performed. Specifically, the first overlapping process and the first joining process are performed as follows.
図７Ｂのように、第１ウェブ１１Ｌの終端部Ｅと第２ウェブ１１Ｒの始端部Ｓとを重ね合わせる工程においては、第２パッド３１Ｒが第１パッド３１Ｌに向って変位することで、第１パッド３１Ｌの吸着面３１ｆと第１パスライン１Ｌ上の第１ウェブ１１Ｌとが互いに平行な状態のまま、第１パッド３１Ｌと第２パッド３１Ｒとの間に両ウェブが挟まれて前記第１の継ぎ工程が実行される。 As shown in FIG. 7B, in the process of overlapping the terminal end E of the first web 11L and the starting end S of the second web 11R, the second pad 31R is displaced toward the first pad 31L, so that the first While the adsorption surface 31f of the pad 31L and the first web 11L on the first pass line 1L remain parallel to each other, both webs are sandwiched between the first pad 31L and the second pad 31R, and the first A splicing process is performed.
　本例では、第１および第２パッドの吸着面は、常に鉛直面に沿っており、互いに平行で、かつ、第１または第２パスライン上のウェブに対しても、共に平行である。
　両パッド３１Ｌ，３１Ｒはウェブに直交する水平軸に沿って往復移動し、ウェブとの上記幾何学的関係が維持されたまま、両ウェブを挟み付ける。
本例では、図９Ａのグレーで着色した始端部Ｓに接着剤が設けられており、前記ウェブの挟持により、両ウェブが接合される。 In this example, the suction surfaces of the first and second pads are always along a vertical plane, parallel to each other, and also parallel to the web on the first or second pass line.
Both pads 31L and 31R reciprocate along a horizontal axis perpendicular to the webs, and sandwich both webs while maintaining the above-mentioned geometrical relationship with the webs.
In this example, an adhesive is provided at the starting end S colored in gray in FIG. 9A, and both webs are joined by sandwiching the webs.
第１の重ね合わせ工程および第１の継ぎ工程の後に、図４の第１パスライン１Ｌに平行な図５の第２パスライン１Ｒに変更させるように、図４の排出ロール６を第１のロール位置Ｐ１から図５の第２のロール位置Ｐ２に変位させる第１変位工程を実行する。なお、この第１変位工程に先立って図７Ｂの各パッドの吸着を解除すると共に第２パッド３１Ｒは第２パスラインから退避した原点位置に戻る。 After the first overlapping process and the first joining process, the discharge roll 6 in FIG. 4 is moved to the first pass line 1R in FIG. A first displacement step of displacing the roll from the roll position P1 to the second roll position P2 in FIG. 5 is executed. Note that, prior to this first displacement step, the suction of each pad in FIG. 7B is released, and the second pad 31R returns to the original position where it was evacuated from the second pass line.
図３および図４の第１の重ね合わせ工程および第１の継ぎ工程において、第１ウェブ１１Ｌを第１パスライン１Ｌ上に保持するように排出ロール６が第１のロール位置Ｐ１に配置される。一方、図６の第２搬送工程において、排出ロール６が第２ウェブ１１Ｒを第２パスライン１Ｒ上に保持するように第２のロール位置Ｐ２に配置される。このように、各ウェブは鉛直面に沿った各パスラインに保持されるので、ウェブは各パッドの吸着面３１ｆに対し、常に平行であり、そのため、吸着時にウェブに皺の生じるおそれはない。 In the first overlapping step and first joining step in FIGS. 3 and 4, the discharge roll 6 is arranged at the first roll position P1 so as to hold the first web 11L on the first pass line 1L. . On the other hand, in the second conveyance step of FIG. 6, the discharge roll 6 is arranged at the second roll position P2 so as to hold the second web 11R on the second pass line 1R. In this way, since each web is held on each pass line along the vertical plane, the web is always parallel to the suction surface 31f of each pad, and therefore there is no risk of wrinkles occurring in the web during suction.
以上は第１ウェブ１１Ｌに第２ウェブ１１Ｒを継ぐ場合について説明した。第２ウェブ１１Ｒに第１ウェブ１１Ｌを継ぐ場合は、上述した場合と同様であるが、以下、簡単に説明する。 The case where the second web 11R is joined to the first web 11L has been described above. The case where the first web 11L is joined to the second web 11R is similar to the case described above, but will be briefly explained below.
この場合、図７Ｃのように、前述の第２搬送工程後に第２ウェブ１１Ｒの終端部Ｅと第１ウェブ１１Ｌの始端部Ｓとを第１パッド３１Ｌと第２パッド３１Ｒとの間で挟んで終端部Ｅと始端部Ｓとを重ね合わせる第２の重ね合わせ工程と、始端部Ｓと終端部Ｅとを接合して第２ウェブ１１Ｒに第１ウェブ１１Ｌを継ぐ第２の継ぎ工程とが実行される。 In this case, as shown in FIG. 7C, after the second conveyance step described above, the terminal end E of the second web 11R and the starting end S of the first web 11L are sandwiched between the first pad 31L and the second pad 31R. A second overlapping process of overlapping the terminal end E and the starting end S, and a second joining process of joining the starting end S and the terminal end E and joining the first web 11L to the second web 11R are performed. be done.
第２の重ね合わせ工程および第２の継ぎ工程の後に図６の第２パスライン１Ｒから第１パスライン１Ｌに変更させるように排出ロール６を第２のロール位置Ｐ２から図１の第１のロール位置Ｐ１に再び変位させる第２変位工程が実行される。 After the second overlapping process and the second joining process, the discharge roll 6 is moved from the second roll position P2 to the first pass line in FIG. 1 so as to change from the second pass line 1R in FIG. A second displacement step of displacing the roller to the roll position P1 again is executed.
第２の重ね合わせ工程および第２の継ぎ工程において、図６の第２ウェブ１１Ｒを第２パスライン１Ｒ上に保持するように排出ロール６が第２のロール位置Ｐ２に配置される。その後、図１の第１搬送工程において、第１ウェブ１１Ｌを第１パスライン１Ｌ上に保持するように排出ロール６が第１のロール位置Ｐ１に配置される。 In the second overlapping process and the second joining process, the discharge roll 6 is arranged at the second roll position P2 so as to hold the second web 11R in FIG. 6 on the second pass line 1R. Thereafter, in the first conveyance step of FIG. 1, the discharge roll 6 is arranged at the first roll position P1 so as to hold the first web 11L on the first pass line 1L.
図７Ｃにおいて、第２ウェブ１１Ｒの終端部Ｅと第１ウェブ１１Ｌの始端部Ｓとを重ね合わせる工程において、第１パッド３１Ｌが第２パッド３１Ｒに向かって変位することで、第２パッド３１Ｒの吸着面３１ｆと第２パスライン１Ｒ上の第２ウェブ１１Ｒとが互いに平行な状態のまま、第１パッド３１Ｌと第２パッド３１Ｒとの間に両ウェブが挟まれる。 In FIG. 7C, in the process of overlapping the terminal end E of the second web 11R and the start end S of the first web 11L, the first pad 31L is displaced toward the second pad 31R, so that the second pad 31R While the suction surface 31f and the second web 11R on the second pass line 1R remain parallel to each other, both webs are sandwiched between the first pad 31L and the second pad 31R.
なお、スプライス装置１０は、切断工程と継ぎ工程の順序は限定されず、最終的にウェブ同士をスプライスできればよく、例えば、切断工程と接合工程とを同時に行い、または、継ぎ工程の後にウェブを切断するものであってもよいし、切断工程後に継ぎ工程を行ってもよい。
但し、先行のウェブを切断する前に、当該ウェブの終端部をパッドで吸着保持するのが好ましいだろう。例えば、図７Ａの第１ウェブ１１Ｌが第１パスライン１Ｌ上で停止した直後に、第１パッド３１Ｌで当該第１ウェブの終端部Ｅとなる部位を吸着保持し、その後、図７Ｂの第１カッタ２１Ｌで第１ウェブ１１Ｌを切断するのが好ましい。 Note that the splicing device 10 is not limited to the order of the cutting process and the splicing process, as long as the webs can be spliced together in the end.For example, the splicing apparatus 10 may perform the cutting process and the joining process at the same time, or may cut the web after the splicing process. Alternatively, a splicing process may be performed after the cutting process.
However, before cutting the preceding web, it may be preferable to suction and hold the end of the web with a pad. For example, immediately after the first web 11L in FIG. 7A stops on the first pass line 1L, the first pad 31L sucks and holds the part that will become the terminal end E of the first web, and then the first web 11L in FIG. It is preferable to cut the first web 11L with the cutter 21L.
これらの吸着保持および切断の際に、図１の排出ロール６が第１のロール位置にあることで、第１ウェブ１１Ｌは第１パスライン１Ｌ上に維持される。すなわち、第１供給ロール５Ｌから排出ロール６に至るまで、第１ウェブ１１Ｌは第１パッド３１Ｌの吸着面に平行な面に沿って延びている。
そのため、第１パッド３１Ｌの図７Ｂの吸着面３１ｆに対し第１ウェブ１１Ｌは、常に平行に配置されており、第１パッド３１Ｌによる第１ウェブ１１Ｌの吸着時に不用意に第１ウェブ１１Ｌに皺が生じるのを防止できる。 During these suction holding and cutting operations, the first web 11L is maintained on the first pass line 1L because the discharge roll 6 in FIG. 1 is in the first roll position. That is, from the first supply roll 5L to the discharge roll 6, the first web 11L extends along a plane parallel to the suction surface of the first pad 31L.
Therefore, the first web 11L is always arranged parallel to the suction surface 31f of the first pad 31L in FIG. can be prevented from occurring.
一方、排出ロール６の移動のタイミングは、先行のウェブの吸着後であれば、いずれのタイミングでもよい。例えば、図７Ａの第１ウェブ１１Ｌの終端部Ｅとなる部位を吸着した後であれば、第１ウェブ１１Ｌの切断前に図１の第１のロール位置Ｐ１から第２のロール位置Ｐ２に変位させてもよい。また、この吸着後であれば、図７Ｂの重ね合わせおよび継ぎ工程の前に前記排出ロール６の変位を実行してもよい。 On the other hand, the timing of movement of the discharge roll 6 may be any timing after adsorption of the preceding web. For example, after adsorbing the portion that will become the terminal end E of the first web 11L in FIG. 7A, the displacement from the first roll position P1 to the second roll position P2 in FIG. 1 occurs before cutting the first web 11L. You may let them. Further, after this suction, the discharge roll 6 may be displaced before the overlapping and splicing process shown in FIG. 7B.
こうした場合、第１パッド３１Ｌは既に第１ウェブ１１Ｌを吸着保持しており、終端部Ｅに皺の生じる可能性は低いと考えられる。 In such a case, the first pad 31L has already adsorbed and held the first web 11L, and it is considered that there is a low possibility that wrinkles will occur in the terminal end E.

この場合、前述と同様に、各ウェブを継ぐ前後において各ウェブと各パッドの吸着面とが互いに正対した平行な状態となり、そのため、吸着時にウェブに皺の生じるおそれがない。 In this case, as described above, each web and the suction surface of each pad are in a parallel state facing each other before and after joining each web, and therefore there is no possibility that wrinkles will occur in the web during suction.
更に好ましくは、前記第２ウェブ１１Ｒの終端部Ｅと前記第１ウェブ１１Ｌの始端部Ｓとを重ね合わせる工程において、前記第１パッド３１Ｌが前記第２パッド３１Ｒに向かって変位することで、前記第２パッド３１Ｒの吸着面３１ｆと前記第２パスライン１Ｒ上の第２ウェブ１１Ｒとが互いに平行な状態のまま、前記第１パッド３１Ｌと前記第２パッド３１Ｒとの間に前記両ウェブが挟まれる。 More preferably, in the step of overlapping the terminal end E of the second web 11R and the starting end S of the first web 11L, the first pad 31L is displaced toward the second pad 31R, so that the While the suction surface 31f of the second pad 31R and the second web 11R on the second pass line 1R remain parallel to each other, both webs are sandwiched between the first pad 31L and the second pad 31R. It will be done.
