Description

ウエブの継ぎ装置Web splicer
 この発明は、紙、プラスチックフィルム又は金属泊等の単層又は複数層をラミネートしたシート状物等のウエブの継ぎ装置に関するものである。 The present invention relates to a web splicing device such as a sheet-like material laminated with a single layer or a plurality of layers such as paper, a plastic film, or a metal stay.
 この種のウエブの継ぎ装置は、例えば、フィルム加工工程におけるそのフィルム(ウエブ)の繰り出しエリアに設置され、通常は、この継ぎ装置内を前後方向にウエブが走行し(下記実施形態参照)、ウエブは後段の洗浄装置等に送り込まれる。
 そのウエブの継ぎ装置として、上記走行するウエブ(以下、今、送り込まれているウエブを「旧ウエブ」という。)に同前後方向(走行方向)に延びる新ウエブ(旧ウエブに継ぐウエブ)の先端を重ね合わせて、その重ね合わせた部分を切断し、その切断した旧ウエブの後端及び新ウエブの先端に接合テープを貼着して接続する技術がある(下記特許文献1、特許請求の範囲、図1参照)。
This type of web splicing device is installed, for example, in the feeding area of the film (web) in the film processing process, and normally the web travels in the splicing device in the front-rear direction (see the following embodiment). Is sent to a subsequent cleaning device or the like.
As a splicing device for the web, the tip of a new web (web that joins the old web) that extends in the same front-rear direction (running direction) to the traveling web (hereinafter referred to as the “old web”). There is a technique in which the overlapped portion is cut, the overlapped portion is cut, and a joining tape is attached to the rear end of the cut old web and the front end of the new web to connect them (Patent Document 1 and Claims below) FIG. 1).
特開平10-305950号公報Japanese Patent Laid-Open No. 10-305950
 上記ウエブの継ぎ装置において、新旧のウエブを重ね合わせて切断した後、接合テープを貼着して両ウエブを接続する(継ぐ)まで、旧ウエブの走行(繰り出し)は停止される。この停止中は、この継ぎ装置の後段に設けたアキューム装置等によってさらに後段の工程にはウエブが送り続けられる。
 このとき、この継ぎ装置の継ぎ作用の所要時間に応じて上記アキューム装置のウエブ蓄積量が決定され、前記所要時間が長ければ、それだけ蓄積量が多くなってアキューム装置等が大型化する。
In the above web splicing device, the old web running (feeding out) is stopped until the new and old webs are overlapped and cut, and then the joining tape is stuck and both webs are connected (joined). During this stop, the web continues to be sent to the subsequent process by an accumulator provided at the subsequent stage of the splicing device.
At this time, the web accumulation amount of the accumulator device is determined according to the time required for the splicing operation of the splicing device. If the required time is long, the accumulating amount increases accordingly, and the accumulator device and the like increase in size.
 また、上記従来のウエブの継ぎ装置は、上記両ウエブの切断時、その重ね合わせた部分の前後をウエブ保持具で挟持して、その挟持した間を切断し、その切断した旧ウエブの後端(切断端)及び新ウエブの先端を吸引保持しつつ両ウエブの切断した不要部分を除去した後、接合テープを貼着して接続する(特許文献1図1(B)~(E)参照)。
 このとき、ウエブ保持具はウエブに対する上下方向の移動による接離によってウエブを保持し(同文献1図1(B)、(c))、テープ貼着は、上側のウエブ保持具を退去させた後、上側テープ保持具を接合テープを介在してウエブ上面に押しつけてその接合テープを貼着し(同文献1図1(D))、さらに、下側のウエブ保持具を退去させた後、下側テープ保持具を接合テープを介在してウエブに押しつけてその接合テープを貼着する(同文献1図1(E)。
In addition, the conventional web splicing device is configured such that when the two webs are cut, the front and rear of the overlapped portion are sandwiched by a web holder, the portion between the sandwiched portions is cut, and the rear end of the cut old web is cut (Cut end) and unnecessary portions of both webs are removed while sucking and holding the tip of the new web, and then bonded and bonded with a bonding tape (see Patent Document 1 FIGS. 1B to 1E) .
At this time, the web holder holds the web by contact and separation by movement in the vertical direction with respect to the web (FIG. 1 (B), (c)), and tape sticking causes the upper web holder to be moved away. Thereafter, the upper tape holder is pressed against the upper surface of the web through the bonding tape to attach the bonding tape (FIG. 1 (D) of the same document 1), and further, the lower web holder is moved away, The lower tape holder is pressed against the web with the bonding tape interposed therebetween, and the bonding tape is adhered (FIG. 1E of the same document 1).
 このように、ウエブ保持具を上下させたり、テープ保持具を上下させたりする動作を前後して行うと、その動作時間及びその切り替え時間が必要となり、その分、ウエブ継ぎ時間が長くなる。
 近年、上記フィルム加工工程等においては、その加工時間の短縮が叫ばれており、そのためには、継ぎ装置におけるウエブ継ぎ時間の短縮も例外ではない。
 また、ウエブ保持具を上下させたり、テープ保持具を上下させたりする動作は煩雑であり、その構成も複雑となるとともにその動作制御も煩雑である。
As described above, when the web holder is moved up and down or the tape holder is moved up and down, the operation time and the switching time are required, and the web splicing time is increased accordingly.
In recent years, in the film processing step and the like, reduction of processing time has been screamed, and for that purpose, reduction of web splicing time in a splicing device is no exception.
Moreover, the operation | movement which raises / lowers a web holder or raises / lowers a tape holder is complicated, its structure is complicated, and its operation control is also complicated.
 この発明は、以上の実状の下、従来と異なる構成の継ぎ装置及び同方法とすることを第1の課題とし、その装置(方法)において、ウエブの継ぎ時間を短くすることを第2の課題とする。 This invention makes it the 1st subject to set it as the splicing apparatus and the method of a structure different from the past in the above actual condition, and it is the 2nd subject to shorten the splicing time of a web in the apparatus (method). And
 上記課題を達成するため、この発明は、走行する旧ウエブを介して対のロールを上下に対向して設け、その上側ロールを旧ウエブの上表面押圧用とするとともに、下側ロールに新ウエブ先端を吸着支持して旧ウエブの下表面押圧用とし、まず、旧ウエブの走行を中止した状態で前記両ロールを旧ウエブを介在して接圧(接触して圧し合っている状態)し、その状態で旧ウエブを切断する。このとき、その切断部分の前後の旧ウエブを吸着支持している場合は、前記両ロールの旧ウエブを介在した接圧はその旧ウエブの切断後でも良い。また、その切断の前又は後において、上下のロールの少なくとも一方に、接合テープを吸着させておく。つぎに、このロールに接合テープが吸着して両ロールが接圧している状態で、両ロールを回転させて新旧ウエブを走行させ、前記接合テープを両ウエブに貼着して接続するようにしたのである。 In order to achieve the above object, the present invention provides a pair of rolls facing each other up and down via a traveling old web, the upper roll is used for pressing the upper surface of the old web, and the new roll is attached to the lower roll. The front end is sucked and supported for pressing the lower surface of the old web. First, in a state where the running of the old web is stopped, the two rolls are brought into contact with each other via the old web (in a state where they are pressed against each other), In this state, the old web is cut. At this time, when the old webs before and after the cut portion are adsorbed and supported, the contact pressure through the old webs of both rolls may be after the old webs are cut. Further, before or after the cutting, the joining tape is adsorbed to at least one of the upper and lower rolls. Next, in a state where the bonding tape is adsorbed to this roll and both rolls are in contact with each other, both the rolls are rotated to run the old and new webs, and the bonding tape is attached to and connected to both webs. It is.
 このようにすれば、ウエブの走行中止時間は、両ロールを旧ウエブを介在した接圧後からその接圧を開放するまでであり、従来に比べれば短縮できて、上記第2の課題を達成し得る。また、その両ロールによる継ぎ構成は従来にない新規なものであって、上記第1の課題を達成する。 In this way, the travel stop time of the web is from the time when both rolls are brought into contact with each other through the old web until the contact pressure is released, which can be shortened compared to the conventional case, and the second problem is achieved. Can do. Moreover, the joint structure by the both rolls is a novel one that has not been achieved so far, and achieves the first problem.
 この両ウエブの継ぎにおいて、上記両ロールが接圧している状態で、その接圧点から旧ウエブの切断端までのその旧ウエブの長さと同接圧点から新ウエブの先端までの下側貼り付けロールの周長が同じであれば(図3(a)参照)、両ロールが回転すると、旧ウエブの切断端と新ウエブの先端が突き合わさった状態となり、その突き合わさった両端に亘って接合テープが貼着される(図3(c)参照)。一方、同接圧点から旧ウエブの切断端までのその旧ウエブの長さに比べ同接圧点から新ウエブの先端までの下側貼り付けロールの周長が短いのであれば、両ロールが回転すると、旧ウエブの切断端と新ウエブの先端が重なった状態となり、その重なった端縁を境にして両ウエブに亘って接合テープが貼着される。 
 これらの場合、両ロールの一方に接合テープが吸着されておれば、その接合テープを両ウエブの端縁を境にして両ウエブの端間に貼着するものとすることができる。また、両ロールに接合テープがそれぞれ吸着されておれば、両接合テープをそのウエブの端縁を境にして両ウエブの端間の両面に貼着するものとすることができる。さらに、接合テープの両面が粘着層の両面テープであれば、そのテープを両端間に介在するようにし得る(図4参照)。
At the joint of both webs, with the two rolls in contact with each other, the length of the old web from the contact pressure point to the cut end of the old web is the same as that of the old web, and the lower side is applied from the contact pressure point to the tip of the new web. If the circumference of the attaching roll is the same (refer to FIG. 3A), when both rolls rotate, the cut end of the old web and the front end of the new web are brought into contact with each other. A joining tape is affixed (refer FIG.3 (c)). On the other hand, if the circumference of the lower application roll from the contact pressure point to the tip of the new web is shorter than the length of the old web from the contact pressure point to the cut end of the old web, When rotated, the cutting end of the old web and the leading end of the new web are overlapped, and the joining tape is pasted over both webs with the overlapping edge as a boundary.
In these cases, if the joining tape is adsorbed on one of the two rolls, the joining tape can be adhered between the ends of both webs with the edge of both webs as a boundary. Further, if the bonding tape is adsorbed to both rolls, the both bonding tapes can be adhered to both surfaces between the ends of both webs with the edge of the web as a boundary. Furthermore, if both sides of the bonding tape are double-sided tapes with an adhesive layer, the tapes may be interposed between both ends (see FIG. 4).
 この発明に係るウエブ継ぎ装置の具体的な構成としては、一方向に走行する旧ウエブの切断端と、巻出装置から前記一方向に引き出された新ウエブの先端とを接続するウエブ継ぎ装置において、旧ウエブの走行経路の上下側にその旧ウエブを介して対向する上下の貼り付けロールを設けるとともに、その上側貼り付けロールの前記走行経路の前段に旧ウエブの切断刃を設け、新ウエブの先端が下側貼り付けロールに吸着されるとともに両ロールの少なくとも一方に接合テープが吸着され、上下の貼り付けロールを旧ウエブを介在して接圧するとともに、前記切断刃によって旧ウエブを前記両ロールが接圧した接圧点の前段で切断し、両ロールを両ウエブの前記走行方向に回転させて接合テープを旧ウエブの切断端及び新ウエブの先端に接着して、旧ウエブの切断端と新ウエブの先端とを継ぎ合わせる構成を採用することができる。 As a specific configuration of the web splicing device according to the present invention, in the web splicing device that connects the cut end of the old web traveling in one direction and the front end of the new web drawn in the one direction from the unwinding device. The upper and lower application rolls facing each other through the old web are provided on the upper and lower sides of the travel path of the old web, and the cutting blade of the old web is provided in the front stage of the travel path of the upper application roll. The front end is adsorbed to the lower application roll, the joining tape is adsorbed to at least one of the two rolls, the upper and lower application rolls are brought into contact with each other through the old web, and the old web is attached to the both rolls by the cutting blade. Cut at the front stage of the contact pressure point where the contact pressure is applied, rotate both rolls in the running direction of both webs, and bond the joining tape to the cutting edge of the old web and the tip of the new web Te, it is possible to adopt a configuration splicing the leading end of the expiring web of the cut end and the new web.
 この構成において、上記下側貼り付けロールに接合テープが吸着されるものとするとともに、その接合テープを表裏両面が粘着層である両面テープとし、旧ウエブの切断後、両ロールを両ウエブの前記走行方向に回転させて接合テープを旧ウエブの切断端及び新ウエブの先端の間に介在してその両端に接着して、旧ウエブの切断端(後端)と新ウエブの先端とを重ねて継ぎ合わせることができる。 In this configuration, the bonding tape is to be adsorbed to the lower application roll, and the bonding tape is a double-sided tape whose both front and back surfaces are adhesive layers. Rotate in the running direction, and the bonding tape is interposed between the cutting edge of the old web and the leading edge of the new web and bonded to both ends, and the cutting edge (rear edge) of the old web and the leading edge of the new web are overlapped Can be spliced.
 また、上記上側貼り付けロールに接合テープが吸着されるものとし、その上側貼り付けロールに回転停止位置調整用ウエイトを取付け、そのウエイトによって上下の貼り付けロールの接圧時、前記吸着された接合テープが、両ロールを両ウエブの前記走行方向に回転させて接合テープを旧ウエブの切断端及び新ウエブの先端に接着するように、上記接圧点から上側貼り付けロールの周方向に離れた点に位置するようにすることができる。
 このとき、そのウエイトを上側貼り付けロールの軸心周りに回転・固定し得るようにすれば、ロールの回転停止位置を任意に調整できるため、接合テープの貼着位置を上記接圧点から上側貼り付けロールの周方向に離れた任意の位置(点)に調整し得る。
Further, the bonding tape is adsorbed to the upper application roll, and a rotation stop position adjusting weight is attached to the upper application roll, and the adsorbed bonding is performed when the upper and lower application rolls are contacted by the weight. The tape is separated from the contact point in the circumferential direction of the upper adhesive roll so that both rolls are rotated in the running direction of both webs and the joining tape is adhered to the cut end of the old web and the tip of the new web. It can be located at a point.
At this time, if the weight can be rotated and fixed around the axis of the upper application roll, the rotation stop position of the roll can be arbitrarily adjusted. It can be adjusted to an arbitrary position (point) separated in the circumferential direction of the sticking roll.
 さらに、上記各構成において、下側貼り付けロールに接合テープが吸着されるものであれば、下側貼り付けロールの新ウエブ走行方向前方に、その下側貼り付けロールに接圧・退避可能な転移ロールを設け、この転移ロール上で、下側貼り付けロールとその転移ロールの間を通って吸着された新ウエブの先端に接合テープの貼着を行い、その転移ロールを下側貼り付けロールに接圧した状態で、その下側貼り付けロールの回転に伴って転移ロールを回転させて接合テープ付新ウエブの先端を下側貼り付けロールに転移吸着する構成を採用することができる。
 通常、下側貼り付けロールへの接合テープの吸着は、その接合テープの粘着層を表にして行う必要があり、この態様を下側貼り付けロール上で行うには、まず、接合テープをロールに吸着し、その後、新ウエブの先端をその接合テープに接着(固定)することとなる。しかし、転移ロールを使用すれば、その転移ロールに新ウエブを吸着させた後、接合テープをその新ウエブの端に接着すれば良いため、その作業性が良いものとなる。
 なお、転移ロール上で、新ウエブの先端の切り揃えを行えば、その先端の切断によって転移ロール(下側貼り付けロール)への新ウエブの巻回長さ(吸着長さ)を所要のものとすることができる。
Further, in each of the above-described configurations, if the bonding tape is adsorbed to the lower adhesive roll, the lower adhesive roll can be contacted and retracted to the lower adhesive roll in front of the new web traveling direction. A transfer roll is provided, and on this transfer roll, a bonding tape is attached to the tip of a new web adsorbed between the lower application roll and the transfer roll, and the transfer roll is attached to the lower application roll. In a state in which the lower adhesive roll is rotated, the transfer roll is rotated with the lower adhesive roll rotating, and the tip of the new web with the bonding tape is transferred and adsorbed to the lower adhesive roll.
Usually, the adsorption of the bonding tape to the lower application roll needs to be performed with the adhesive layer of the bonding tape as a table. To perform this mode on the lower application roll, first, the bonding tape is rolled. Then, the tip of the new web is bonded (fixed) to the bonding tape. However, if a transfer roll is used, the workability is improved because the bonding tape can be adhered to the end of the new web after adsorbing the new web to the transfer roll.
If the leading edge of the new web is aligned on the transition roll, the winding length (adsorption length) of the new web around the transition roll (lower application roll) is required by cutting the leading edge. It can be.
 上記各構成のウエブ継ぎ装置において、上記新ウエブの先端を下側貼り付けロールに吸着する際、その新ウエブの先端近くを吸着具で吸引保持するものとすることができる。このようにすれば、新ウエブの先端が動き難くなるため、その先端の下側貼り付けロールへの吸着作業が円滑になる。
 また、上記上下の貼り付けロールの少なくとも一方の上記接圧面を弾性材で形成すれば、所要の接圧力を得て円滑なウエブの走行を担保することができる。
In the web splicing device having each configuration described above, when the leading edge of the new web is attracted to the lower application roll, the vicinity of the leading edge of the new web can be sucked and held by the suction tool. This makes it difficult for the tip of the new web to move, so that the suction operation to the lower application roll of the tip becomes smooth.
Further, if at least one of the pressure contact surfaces of the upper and lower application rolls is made of an elastic material, a required contact pressure can be obtained to ensure smooth running of the web.
 この発明に係るウエブ継ぎ方法の具体的な構成としては、一方向に走行する旧ウエブの切断端と、巻出装置から前記一方向に引き出された新ウエブの先端とを接続するウエブ継ぎ方法において、
 旧ウエブの走行経路の上下側にその旧ウエブを介して対向する上下の貼り付けロールが設けられており、
 上記新ウエブの先端を上記下側貼り付けロールに吸着するとともに両ロールの少なくとも一方に接合テープを吸着し、その上下の貼り付けロールを接近させて旧ウエブを介在して接圧し、その状態で又はその接圧前に、切断刃によって前記両ロールが接圧した接圧点の走行経路前段の旧ウエブを切断し、その後、両ロールを回転させて新旧両ウエブを前記走行方向に走行させるとともに前記接合テープを旧ウエブの切断端及び新ウエブの先端に接着して、旧ウエブの切断端と新ウエブの先端とを接続する構成を採用することができる。
As a specific configuration of the web splicing method according to the present invention, in the web splicing method for connecting the cut end of the old web traveling in one direction and the front end of the new web drawn in the one direction from the unwinding device. ,
Up and down pasting rolls facing each other through the old web are provided on the upper and lower sides of the traveling path of the old web,
Adhere the tip of the new web to the lower application roll, adsorb the joining tape to at least one of the two rolls, bring the upper and lower application rolls close together, and contact the pressure with the old web. Alternatively, before the contact pressure, the old web at the front stage of the travel path at the contact pressure point where both rolls are in contact with each other by the cutting blade is cut, and then both rolls are rotated to cause both the new and old webs to travel in the travel direction. It is possible to employ a configuration in which the joining tape is bonded to the cut end of the old web and the tip of the new web to connect the cut end of the old web and the tip of the new web.
 この構成において、上記下側貼り付けロールに接合テープが吸着されるものであれば、その接合テープを表裏両面が粘着層である両面テープとし、旧ウエブの切断後、両ロールを両ウエブの前記走行方向に回転させて接合テープを旧ウエブの切断端及び新ウエブの先端の間に介在してその両端に接着して、旧ウエブの切断端(後端)と新ウエブの先端とを重ねて継ぎ合わせる構成とすることができる。 In this configuration, if the bonding tape is adsorbed to the lower application roll, the bonding tape is a double-sided tape whose both front and back surfaces are adhesive layers, and after cutting the old web, Rotate in the running direction, and the bonding tape is interposed between the cutting edge of the old web and the leading edge of the new web and bonded to both ends, and the cutting edge (rear edge) of the old web and the leading edge of the new web are overlapped It can be configured to be joined.
 また、上記各ウエブ継ぎ方法において、上記下側貼り付けロールの新ウエブ走行方向前方に設けられてその下側貼り付けロールに接圧・退避可能な転移ロールと前記下側貼り付けロールとの間に、新ウエブを通し、その通した新ウエブを介在して転移ロールを下側貼り付けロールに接圧するとともに新ウエブを転移ロールに吸着し、その状態で、転移ロール上で、新ウエブの先端の切り揃え及びその先端への接合テープの貼着を行い、その後、下側貼り付けロールの回転に伴って前記転移ロールを回転させて接合テープ付新ウエブの先端を下側貼り付けロールに転移吸着するものとすることができる。 Further, in each of the above web splicing methods, the lower adhesive roll is provided between the lower adhesive roll and the lower adhesive roll, which is provided in front of the new web traveling direction and can be contacted and retracted to the lower adhesive roll. Passing the new web through the new web, the transfer roll is brought into contact with the lower application roll and the new web is adsorbed to the transfer roll. In this state, the tip of the new web is placed on the transfer roll. And then joining the adhesive tape to the tip, and then rotating the transfer roll along with the rotation of the lower adhesive roll to transfer the tip of the new web with the adhesive tape to the lower adhesive roll It can be adsorbed.
 さらに、上記各構成のウエブ継ぎ方法において、上記上側貼り付けロールに接合テープが吸着されるものであれば、その上側貼り付けロールに回転停止位置調整用ウエイトを取付け、そのウエイトによって上下の貼り付けロールの接圧時、前記吸着された接合テープが、両ロールを両ウエブの前記走行方向に回転させて接合テープを旧ウエブの切断端及び新ウエブの先端に接着するように、上記接圧点から上側貼り付けロールの周方向に離れた点に位置するようにすることができる。
 このとき、そのウエイトを上側貼り付けロールの軸心周りに回転・固定し得るようにすれば、ロールの回転停止位置を任意に調整できるため、接合テープの貼着位置を上記接圧点から上側貼り付けロールの周方向に離れた任意の位置(点)に調整し得る。
Furthermore, in the web splicing method of each configuration described above, if the bonding tape is adsorbed to the upper application roll, a rotation stop position adjusting weight is attached to the upper application roll, and the upper and lower applications are attached by the weight. At the time of the contact pressure of the roll, the adhering bonding tape rotates the both rolls in the running direction of both webs so that the bonding tape is bonded to the cut end of the old web and the tip of the new web. It can be made to be located in the point away from the circumferential direction of the upper side sticking roll.
At this time, if the weight can be rotated and fixed around the axis of the upper application roll, the rotation stop position of the roll can be arbitrarily adjusted. It can be adjusted to an arbitrary position (point) separated in the circumferential direction of the sticking roll.
 また、上記上下の貼り付けロールの少なくとも一方の上記接圧面を弾性材で形成すれば、所要の接圧力を得て円滑なウエブの走行を担保することができる。
 さらに、上記各ウエブ継ぎ方法において、上記新ウエブの先端を下側貼り付けロールに吸着する際、その新ウエブの先端近くを吸着具で吸引保持するようにすることができる。
Further, if at least one of the pressure contact surfaces of the upper and lower application rolls is made of an elastic material, a required contact pressure can be obtained to ensure smooth running of the web.
Further, in each of the web splicing methods, when the leading edge of the new web is attracted to the lower sticking roll, the vicinity of the leading edge of the new web can be sucked and held by the suction tool.
 この発明は、以上のように構成したので、簡単な構成によってウエブの接続を円滑に行うことができる。 Since the present invention is configured as described above, the web can be smoothly connected with a simple configuration.

 この発明の一実施形態を図1A~図1L、図2A、図2Bに示し、この実施形態のウエブ継ぎ装置Sは、二軸ターレット自動巻き出し装置(図示せず)からフィルム加工工程のフィルム(ウエブ)が繰り出されるエリアに設置され、後段に、アキューム装置(図示せず)やダンサーローラ装置(図示せず)等を介してそのフィルム洗浄装置等を設置する。その四角枠状のフレームFにその後側(図1Aにおいて左側)から前側(同右側)にフィルム(旧ウエブ)W1が走行し、その走行経路の上下に貼り付けロール1、2が設けられている。この両ロール1、2の長さや外径は適宜に決定すれば良いが、この実施形態では、ロール1の長さ:1600mm、外径:125mm、ロール2の外径:250mmとした。 An embodiment of the present invention is shown in FIGS. 1A to 1L, 2A, and 2B, and a web splicing device S of this embodiment is a film (in a film processing step) from a biaxial turret automatic unwinding device (not shown). It is installed in the area where the web) is fed out, and the film cleaning device and the like are installed in the subsequent stage via an accumulator device (not shown), a dancer roller device (not shown) or the like. A film (old web) W1 travels from the rear side (left side in FIG. 1A) to the front side (same right side) of the square frame F, and pasting rolls 1 and 2 are provided above and below the travel path. . The lengths and outer diameters of the rolls 1 and 2 may be determined as appropriate. In this embodiment, the length of the roll 1 is 1600 mm, the outer diameter is 125 mm, and the outer diameter of the roll 2 is 250 mm.
 この両ロール1、2はその一部がパンチングメタルによって形成されて接合テープTの吸着部1a、2aとなっており(図2A参照)、その内部は適宜に吸引される。この吸着部1a、2aの大きさ・位置は接合テープTが円滑に吸着されて吸気の漏れがないように適宜に決定する。例えば、接合テープTが長さ:1500~1600mm、幅:50mmであれば、そのテープTと同一又は少し小さい程度とする。このため、そのパンチングメタル部分(吸着部)1a、2aに接合テープTを置くと、その接合テープTはロール表面に吸着される。図中、3はウエブWの案内ロール、4は吸気ホースである。 These rolls 1 and 2 are partly formed of punching metal to form the adsorbing portions 1a and 2a of the joining tape T (see FIG. 2A), and the inside is sucked appropriately. The sizes and positions of the suction portions 1a and 2a are appropriately determined so that the joining tape T is smoothly sucked and there is no leakage of intake air. For example, if the joining tape T has a length of 1500 to 1600 mm and a width of 50 mm, it is the same as or slightly smaller than the tape T. For this reason, when the bonding tape T is placed on the punching metal portions (adsorption portions) 1a and 2a, the bonding tape T is adsorbed on the roll surface. In the figure, 3 is a guide roll of the web W, and 4 is an intake hose.
 上側の貼り付けロール1は、その周面が樹脂層(ゴム)による弾性面となっており、フレームFに対して操作側である左方(図1Aにおいて手前方向)に取り出し可能となっている(図2A鎖線状態参照)。この取り出し時、上側貼り付けロール1に連結された吸気ホース4は、そのガイド樋4a上をそのロール1に連れて引き出される。
 また、その上側貼り付けロール1の軸に回転停止位置調整用ウエイト30が取付けられており(図2A参照)、このウエイト30によって上側貼り付けロール1は、常時、所定回転位置で停止する。このウエイト30は、図2A(b)に示すように、ロール軸の上方部が二股片に分かれ、その両片にボルト・ナット31がねじ通されており、そのボルト・ナット31を弛めてロール軸周囲の所要の位置に回し、ボルト・ナット31を締結することによってその位置に固定し得る。このため、前記上側貼り付けロール1の所定回転位置は任意に変更可能である。この実施形態では、ウエイト30によって、他の拘束力がなければ、何れの回転位置においても、図3(a)に示す、接合テープT1が両ロール1、2の接圧点aから所要角度θ1、例えば、137.5度に位置するように、上側貼り付けロール1が回転・停止する。
The peripheral surface of the upper attaching roll 1 is an elastic surface made of a resin layer (rubber), and can be taken out to the left side (front side in FIG. 1A) on the operation side with respect to the frame F. (See FIG. 2A chain line state). At this time, the intake hose 4 connected to the upper attaching roll 1 is pulled out along the guide rod 4a with the roll 1.
A rotation stop position adjusting weight 30 is attached to the shaft of the upper application roll 1 (see FIG. 2A), and the upper application roll 1 is always stopped at a predetermined rotation position by the weight 30. As shown in FIG. 2A (b), the weight 30 has an upper portion of the roll shaft divided into two forks, and bolts and nuts 31 are threaded through the two pieces, and the bolts and nuts 31 are loosened. The bolts and nuts 31 can be fastened to a required position around the roll shaft and fixed at that position by fastening the bolts and nuts 31. For this reason, the predetermined rotation position of the upper application roll 1 can be arbitrarily changed. In this embodiment, if there is no other restraining force due to the weight 30, the joining tape T1 shown in FIG. 3 (a) is at the required angle θ1 from the contact pressure point a of both rolls 1 and 2 at any rotational position. For example, the upper application roll 1 rotates and stops so as to be positioned at 137.5 degrees.
 上側貼り付けロール1のウエブ走行経路の前段には前後対のバキュームボックス5、5が設けられ、この対のバキュームボックス5、5の間に切断刃6が位置している。その前段(図1Aにおいて左側)のバキュームボックス5はエアシリンダ5aによって下記支持ブロック7に対して昇降可能となっており、切断刃6の取り替え時、上昇させてその取り替えをし易くする。切断刃6もその支持ブロック7に対してエアシリンダ等によって昇降可能とし得る。
 これらの上側貼り付けロール1、バキュームボックス5、エアシリンダ5aは支持ブロック7に取付けられており、その支持ブロック7はフレームF上のエアシリンダ8によって昇降可能に支持されている。このエアシリンダ8は、その両側にガイド杆8a、8aを有して前記支持ブロック7を安定して昇降する。以下の各エアシリンダ11a、11b、14a、14b、15a、20もそれぞれガイド杆を有してロッドの安定的な進退を行い得るようにしており、そのガイド杆の説明は省略する。
A pair of front and rear vacuum boxes 5 and 5 are provided in the front stage of the web traveling path of the upper sticking roll 1, and a cutting blade 6 is positioned between the pair of vacuum boxes 5 and 5. The vacuum box 5 in the previous stage (left side in FIG. 1A) can be moved up and down with respect to the support block 7 below by an air cylinder 5a, and is raised when the cutting blade 6 is replaced to facilitate the replacement. The cutting blade 6 can also be moved up and down with respect to the support block 7 by an air cylinder or the like.
The upper attaching roll 1, the vacuum box 5, and the air cylinder 5 a are attached to a support block 7, and the support block 7 is supported by an air cylinder 8 on the frame F so as to be movable up and down. The air cylinder 8 has guide rods 8a, 8a on both sides thereof, and moves up and down the support block 7 stably. Each of the following air cylinders 11a, 11b, 14a, 14b, 15a, 20 also has a guide rod so that the rod can be stably advanced and retracted, and description of the guide rod is omitted.
 そのエアシリンダ8によって支持ブロック7が下降すると、上側貼り付けロール1、バキュームボックス5及び切断刃6が旧ウエブW1の走行経路に接し、対のバキュームボックス5、5によってウエブW1が吸着されて固定支持され、それと同時に切断刃6によってウエブW1が両バキュームボックス5、5間で吸着支持された状態で切断される。 When the support block 7 is lowered by the air cylinder 8, the upper attaching roll 1, the vacuum box 5 and the cutting blade 6 come into contact with the travel path of the old web W1, and the web W1 is adsorbed and fixed by the pair of vacuum boxes 5 and 5. At the same time, the web W1 is cut by the cutting blade 6 while being sucked and supported between the vacuum boxes 5 and 5.
 下側の貼り付けロール2は、待機時、図3(a)に示す、上記パンチングメタル部分(吸着部)2aに吸着された接合テープT2が両ロール1、2の接圧点aから所要角度θ2、例えば、68.8度に位置するようになっている。また、この下側貼り付けロール2は、所要角度、例えば、180度右回転された位置で後記転移ロール16が接圧(ニップ)するようになっている。 When the lower application roll 2 is on standby, the bonding tape T2 adsorbed by the punching metal portion (adsorption part) 2a shown in FIG. It is located at θ2, for example, 68.8 degrees. In addition, the transfer roller 16 described later is in contact pressure (nip) with the lower application roll 2 at a required angle, for example, a position rotated to the right by 180 degrees.
 なお、この下側貼り付けロール2の回転位置θ2及び上記上側貼り付けロール1の回転位置θ1は、図1Gに示す両ロール1、2の接圧時点におけるその接圧点a(図3(a)参照)から両ロール1、2が回転した際、両ロール1、2に吸着された接合テープT1、T2が重なり合うように(接圧点aから接合テープT1、T2までの両ロール1、2の外周面弧長が同じとなるように)設定するものであり、この実施形態では、ロール1の外径:125mm、ロール2の外径:250mmとしたため、前記接圧点aから、前者θ1を137.5度の位置、後者θ2を68.8度の位置とした。このため、ロール1、2外径に応じてその位置θ1、θ2は適宜に設定する。 The rotation position θ2 of the lower application roll 2 and the rotation position θ1 of the upper application roll 1 are the contact pressure point a (see FIG. 3 (a) at the time of contact between the rolls 1 and 2 shown in FIG. 1G. )), When both rolls 1 and 2 rotate, both rolls 1 and 2 from contact pressure point a to joining tapes T1 and T2 overlap so that the joining tapes T1 and T2 adsorbed to both rolls 1 and 2 overlap. In this embodiment, since the outer diameter of the roll 1 is 125 mm and the outer diameter of the roll 2 is 250 mm, the former θ1 is determined from the contact point a. Was set at a position of 137.5 degrees, and the latter θ2 was set at a position of 68.8 degrees. Therefore, the positions θ1 and θ2 are appropriately set according to the outer diameters of the rolls 1 and 2.
 この下側貼り付けロール2は2段の大小のエアシリンダ11a、11bによって昇降自在なベース10に設けられている(図2A参照)。このベース10は、大エアシリン11aによって所要高さ、例えば、300mm昇降し、小エアシリンダ11bによってさらに所要高さ、例えば、25mm昇降する。このように、大小のダブルシリンダとしたのは、長伸縮シリンダでは、昇降精度が低い上に、大型化するからである。また、その両シリンダを並列配置としたのは、高さを抑えるためであり、高さ制限がなければ、直列配置とすることができる。 The lower pasting roll 2 is provided on a base 10 that can be moved up and down by two stages of large and small air cylinders 11a and 11b (see FIG. 2A). The base 10 is moved up and down by a large air cylinder 11a, for example, 300 mm, and is further moved up and down by a small air cylinder 11b, for example, 25 mm. The reason why the large and small double cylinders are used in this way is that the long telescopic cylinders are not only low in raising / lowering accuracy but also large. Further, the reason why both cylinders are arranged in parallel is to suppress the height, and if there is no height restriction, they can be arranged in series.
 また、このベース10には下側貼り付けロール2を回転・停止するロータリーアクチュエータ12が設けられており、このロータリーアクチュエータ12によって下側貼り付けロール2が所要角度回転・停止する。
 下側貼り付けロール2の前段には、2段の大小のエアシリンダ14a、14bによって昇降可能な待機位置用バキュームボックス13が設けられ、さらに、その前段にエアシリンダ15aによって昇降可能な昇降ロール15が設けられている。
The base 10 is provided with a rotary actuator 12 that rotates and stops the lower application roll 2. The rotary actuator 12 rotates and stops the lower application roll 2 by a required angle.
A standby position vacuum box 13 that can be moved up and down by two large and small air cylinders 14a and 14b is provided in the front stage of the lower sticking roll 2, and a lift roll 15 that can be lifted and lowered by the air cylinder 15a in the front stage. Is provided.
 フレームFの前面(図1Aにおいて右側面)に表面が例えばフッ素樹脂コーティング等の非貼着処理がなされた転移ロール16がロータリーアクチュエータ17によって起伏自在に設けられて下側貼り付けロール2に接圧・退避可能となっている。このロール16は、常時、起立されて退避しており、倒伏することによって、上記待機状態から右に180度回転した下側貼り付けロール2に接圧する(図1B等参照)。このロール16も一部表面がパンチングメタル16aによって形成され、その内部は吸引可能(バキューム可能)となっている(図2A参照)。
 そのパンチングメタル部分(吸着部)16aは、両ロール2,16が接圧した点からのロール16の周長が同接圧点から下側貼り付けロール2のパンチングメタル部分(吸着部)2aまでの周長と同じとなっている。
A transfer roll 16 whose surface is not adhered to the front surface of the frame F (the right side surface in FIG. 1A), such as a fluororesin coating, is provided by a rotary actuator 17 so that it can be raised and lowered.・ Evacuation is possible. This roll 16 always stands up and retreats, and by lying down, comes into contact with the lower application roll 2 rotated 180 degrees to the right from the standby state (see FIG. 1B and the like). A part of the surface of the roll 16 is formed of a punching metal 16a, and the inside thereof can be sucked (vacuumable) (see FIG. 2A).
The punching metal portion (adsorption portion) 16a is such that the circumference of the roll 16 from the point where both rolls 2 and 16 are in contact pressure is from the contact pressure point to the punching metal portion (adsorption portion) 2a of the lower application roll 2. It is the same as the circumference.
 フレームFの上面には、送り出しロール18及びそのロール回転ストッパ19が設けられており、そのストッパ19は、エアシリンダ20によって前後に進退可能となっている(図1Aと図1G参照)。このため、ストッパ19が進行してロール18にウエブW1を介在して接圧すると、ウエブW1の走行は停止する。 The delivery roll 18 and its roll rotation stopper 19 are provided on the upper surface of the frame F, and the stopper 19 can be moved back and forth by an air cylinder 20 (see FIGS. 1A and 1G). For this reason, when the stopper 19 advances and contacts the roll 18 with the web W1 interposed, the traveling of the web W1 stops.
 この実施形態の構成は以上の通りであり、つぎにその作用について説明する。
 通常は、図1Aにおいて、巻出軸(図示せず)から、この継ぎ装置Sにウエブ(旧ウエブ)W1が前後(同1Aにおいて、左から右)に走行し、送り出しロール18から、アキューム装置等に送り出されている。
 この送り出し状態において、今、走行している(送り出している)ウエブW1の終端が近くなると、又は、その前の適宜な時に、まず、待機位置用バキュームボックス13が上昇し(図1Aの鎖線から実線状態に、例えば、125mm上昇し)、その上面と下側貼り付けロール2の上面が同一位置(高さ)になる。続いて、そのボックス13内が吸気(バキューム弁をON(開放、以下同様))され、同時、又は続けて、他の巻出軸(図示せず)から、交換用ウエブ(新ウエブ)W2を引き出し、図1Aに示すように、待機位置用バキュームボックス13に吸着させるとともにその先端W2’を下側貼り付けロール2に置く(預ける)。このとき、図1Aに示すように、新ウエブW2の先端を下側貼り付けロール2の下側面の位置まで垂らし、そのセンタリングを手動によって行う。
The configuration of this embodiment is as described above. Next, the operation will be described.
Normally, in FIG. 1A, a web (old web) W1 travels forward and backward (left to right in 1A) from the unwinding shaft (not shown) to this splicing device S, and the accumulating device 18 Etc.
In this sending-out state, when the end of the web W1 that is currently running (sending out) approaches or at an appropriate time before that, the standby position vacuum box 13 first rises (from the chain line in FIG. 1A). For example, the solid line is raised by 125 mm), and the upper surface thereof and the upper surface of the lower application roll 2 are at the same position (height). Subsequently, the inside of the box 13 is inhaled (the vacuum valve is turned on (opened, the same applies hereinafter)), and at the same time or continuously, the replacement web (new web) W2 is drawn from another unwinding shaft (not shown). As shown in FIG. 1A, it is attracted to the standby position vacuum box 13 and its tip W2 ′ is placed on the lower application roll 2 (deposited). At this time, as shown to FIG. 1A, the front-end | tip of the new web W2 is hung down to the position of the lower surface of the lower sticking roll 2, and the centering is performed manually.
 つぎに、上下の貼り付けロール1、2内を吸気する。この吸気状態、又は吸気前に、上側貼り付けロール1を左方(図1Aにおいて手前側)に引き出し、そのロール1のパンチング部(吸気面)1aに接合テープT1をその非貼着面をロール側にして吸着させる。この後、上側貼り付けロール1を押し戻して定位置にセットする。このとき、このロール1はウエイト30によって所要回転角度に位置される。すなわち、図3(a)に示すように、接合テープT1が両ロール1、2の接圧点aから所要角度θ1:137.5度に位置される。 Next, the inside of the upper and lower sticking rolls 1 and 2 is sucked. In this intake state or before intake, the upper application roll 1 is pulled out to the left (front side in FIG. 1A), and the bonding tape T1 is rolled to the punching portion (intake surface) 1a of the roll 1 and the non-adhesion surface is rolled. Adsorb on the side. Thereafter, the upper application roll 1 is pushed back and set at a fixed position. At this time, the roll 1 is positioned at a required rotation angle by the weight 30. That is, as shown in FIG. 3A, the joining tape T1 is positioned at a required angle θ1: 137.5 degrees from the contact pressure point a of both rolls 1 and 2.
 下側貼り付けロール2は、所要角度、例えば、待機位置から右に180度回転させて(旋回させて)、そのパンチング部(吸着面)2aを新ウエブW2の貼着準備位置にセットする(図1B)。続いて、転移ロール16を倒して下側貼り付けロール2に新ウエブW2を介在して接圧するとともに(図1B)、その転移ロール16内を吸気する。この状態で、新ウエブW2を必要があればさらに引き出して転移ロール16に反時計方向に所要長さ(例えば、図1Bにおいて、反時計回りに180度)巻き付けて吸着する。このとき、転移ロール16の吸着部16aはその巻き付けた新ウエブW2の先端縁より内側にあって新ウエブW2を吸着支持する。 The lower application roll 2 is rotated (turned) 180 degrees to the right from a required angle, for example, a standby position, and the punching portion (suction surface) 2a is set at the application preparation position of the new web W2 ( FIG. 1B). Subsequently, the transfer roll 16 is tilted and brought into contact with the lower application roll 2 via the new web W2 (FIG. 1B), and the inside of the transfer roll 16 is sucked. In this state, if necessary, the new web W2 is further pulled out and wound around the transfer roll 16 by a required length in the counterclockwise direction (for example, 180 degrees counterclockwise in FIG. 1B). At this time, the suction portion 16a of the transfer roll 16 is located on the inner side of the leading edge of the wound new web W2, and sucks and supports the new web W2.
 この吸着状態において、新ウエブW2の先端縁をその幅全長に亘って手によって切断する。その切断端が新ウエブW2の先端となり、切断した縁片は適宜に除去する。その切断時、転移ロール16には全長に亘ってカッター溝が形成されて新ウエブW2を通り抜けた切断刃を受ける(逃がす)ようになっている。この切断後、接合テープT2をその粘着面を内側(ロール16側)にしてその幅方向の中央線が新ウエブW2の切断端縁と一致するようにその新ウエブW2に貼着する(図1C)。
 このとき、新ウエブW2の引き出し先端縁が直線状であれば、転移ロール16に吸着させた接合テープT2にその先端縁を貼着しても良い。また、その先端縁が上記カッター溝に対応してその先端縁を切断する必要がなければ、その切断をする必要はない。
In this suction state, the leading edge of the new web W2 is cut by hand over its entire length. The cut end becomes the front end of the new web W2, and the cut edge piece is appropriately removed. At the time of the cutting, the transfer roll 16 is formed with a cutter groove over the entire length to receive (release) the cutting blade that has passed through the new web W2. After this cutting, the bonding tape T2 is adhered to the new web W2 with the adhesive surface inside (the roll 16 side) and the center line in the width direction coincides with the cut edge of the new web W2 (FIG. 1C). ).
At this time, if the leading edge of the new web W2 is linear, the leading edge may be attached to the bonding tape T2 adsorbed to the transfer roll 16. Further, if the tip edge does not need to cut the tip edge corresponding to the cutter groove, it is not necessary to cut the tip edge.
 この新ウエブW2の先端及び接合テープT2が転移ロール16に吸着している状態で、待機位置用バキュームボックス13の吸気を停止する(バキュームOFFとする)とともに下降させる。その後、又は同時に、図1Cに示すように、ロータリーアクチュエータ12によって下側貼り付けロール2を180度左回転させる。このロール2の回転に伴って転移ロール16も回転して接合テープT2付き新ウエブW2を下側貼り付けロール2に送り出し、その接合テープT2の貼着された新ウエブW2の先端が下側貼り付けロール2の吸着部に対応し、その対応時、又は前に、転移ロール16内の吸気を止めることによって、接合テープT2付の新ウエブW2の先端部は下側貼り付けロール2に転移吸着される。 In the state where the tip of the new web W2 and the joining tape T2 are adsorbed to the transfer roll 16, the suction of the standby position vacuum box 13 is stopped (vacuum OFF) and lowered. Thereafter or simultaneously, as shown in FIG. 1C, the lower application roll 2 is rotated 180 degrees counterclockwise by the rotary actuator 12. As the roll 2 rotates, the transfer roll 16 also rotates to feed the new web W2 with the bonding tape T2 to the lower application roll 2, and the tip of the new web W2 to which the bonding tape T2 is attached is attached to the lower side. The tip of the new web W2 with the joining tape T2 is transferred and adsorbed to the lower application roll 2 by stopping the intake air in the transfer roll 16 at or before that corresponding to the adsorbing portion of the application roll 2 Is done.
 このとき、転移ロール16のパンチングメタル部分(吸着部)16aは、両ロール2,16が接圧した点からの周長が同接圧点から下側貼り付けロール2のパンチングメタル部分(吸着部)2aまでの周長と同じとなっているため、接合テープT2付の新ウエブW2の先端部は下側貼り付けロール2のパンチングメタル部分2aに転移(転写)吸着される。このため、下側貼り付けロール2が180度の回転した時点(待機状態)は、図1D、図3(a)に示すように、接合テープT2が両ロール1、2の接圧点aから所要角度θ2:68.8度に位置する。この角度θ2の調整は、接合テープT2付の新ウエブW2の先端部が下側貼り付けロール2に吸着された後、調整することもできる。
 なお、接合テープT2の転移ロール16から下側貼り付けロール2への転移は、ロール16の表面が非貼着処理がなされているため、円滑になされる。また、接合テープT2及び新ウエブW2の先端は転移ロール16に吸着されているが、そのウエブW2とロール2との摩擦力等によって接合テープT2等はロール16からロール2に容易に転移する。このとき、下側貼り付けロール2の吸気力を転移ロール16の吸気力に対し強くしたり、転移時には、ロール16の吸気を中止したりする等の手段を講じることができる。
At this time, the punching metal part (adsorption part) 16a of the transfer roll 16 has a circumferential length from the point where both rolls 2 and 16 are in contact pressure, and the punching metal part (adsorption part) of the lower application roll 2 from the contact pressure point. ) Since the circumference is the same as 2a, the tip of the new web W2 with the joining tape T2 is transferred (transferred) and attracted to the punching metal portion 2a of the lower application roll 2. Therefore, when the lower application roll 2 is rotated 180 degrees (standby state), as shown in FIG. 1D and FIG. The required angle θ2 is 68.8 degrees. The angle θ2 can be adjusted after the tip of the new web W2 with the bonding tape T2 is adsorbed by the lower application roll 2.
Note that the transfer of the joining tape T2 from the transfer roll 16 to the lower application roll 2 is smoothly performed because the surface of the roll 16 is not attached. Further, the tips of the joining tape T2 and the new web W2 are adsorbed to the transfer roll 16, but the joining tape T2 and the like are easily transferred from the roll 16 to the roll 2 by the frictional force between the web W2 and the roll 2. At this time, it is possible to take measures such as increasing the intake force of the lower application roll 2 with respect to the intake force of the transfer roll 16 or stopping the intake of the roll 16 at the time of transfer.
 その後、図1Dに示すように、転移ロール16を起立させる(下側貼り付けロール2から退去させて待機位置に戻す)。このとき、又はその前後において、待機位置用バキュームボックス13内の再吸気を行って新ウエブW2を支持(保持)することができる。 Thereafter, as shown in FIG. 1D, the transfer roll 16 is raised (retracted from the lower sticking roll 2 and returned to the standby position). At this time, or before and after that, re-intake in the standby position vacuum box 13 can be performed to support (hold) the new web W2.
 以上の作用によって、ウエブW1、W2の継ぎ合わせ(スプライス)の準備は完了し(図1Dの状態)、この時まで、旧ウエブW1は走行され続けている(送り出され続けている)。この準備の完了後、その完了スイッチを押す(ONする)と、図1Dから同Eに示すように、下側貼り付けロール2、待機位置用バキュームボックス13及び昇降ロール15が上昇し(例えば、300mm上昇し)、継ぎ合わせ(スプライス)準備が完了する。この昇降ロール15及び待機位置用バキュームボックス13の上昇によって、下側貼り付けロール2から新ウエブW2の大きな垂れ下がりが防止され、弱い吸着力であっても、そのロール2から新ウエブW2が脱落することが防止される。 With the above operation, preparation for splicing of the webs W1 and W2 is completed (the state shown in FIG. 1D), and the old web W1 continues to run (sends out) until this time. After completion of this preparation, when the completion switch is pushed (turned on), as shown in FIG. 1D to E, the lower application roll 2, the standby position vacuum box 13 and the lifting roll 15 are raised (for example, 300mm rise) and the preparation for splicing is completed. The raising of the lifting roll 15 and the standby position vacuum box 13 prevents the new web W2 from drooping greatly from the lower application roll 2, and the new web W2 falls off the roll 2 even with a weak suction force. It is prevented.
 このように、下側貼り付けロール2の下降状態で新ウエブW2及び接合テープT2の吸着作業を行ったのは、そのロール2等の昇降には時間がかかり、それらが下降した作業スペースが広い状態で接合テープT2等の吸着を行い、その接合テープT2等の吸着のスプライス準備ができれば、新ウエブW2を上昇させて、そのスプライスへの上昇時間を短縮させてスプライス時間(ウエブWの走行停止時間)の短縮を図るためである。 As described above, the work of sucking the new web W2 and the joining tape T2 is performed while the lower application roll 2 is lowered, so that it takes time to move the roll 2 up and down, and the work space in which they are lowered is wide. If the splicing of the joining tape T2 or the like is performed in the state and the splicing of the joining tape T2 or the like is ready, the new web W2 is raised to shorten the rise time to the splice and to reduce the splice time (running stop of the web W) This is to shorten the time.
 このスプライス準備の完了後、その完了スイッチを押す(ONする)と、図1Eから同Fに示すように、まず、ロール回転ストッパ19が進行して旧ウエブW1を介在して送り出しロール18に接圧するとともに、旧ウエブW1の巻出軸及び同フィード装置が減速停止し、旧ウエブW1の走行が停止する。前記ストッパ19のロール18への接圧によって、アキューム装置からの旧ウエブW1への引っ張り力は阻止され、この継ぎ装置S内の旧ウエブW1にはテンションがかかっていない状態となる。 After completion of the splice preparation, when the completion switch is pushed (turned ON), as shown in FIG. 1E to F, first, the roll rotation stopper 19 advances to contact the feed roll 18 via the old web W1. In addition, the unwinding shaft and the feed device of the old web W1 are decelerated and stopped, and the travel of the old web W1 is stopped. By the contact pressure of the stopper 19 to the roll 18, the pulling force from the accumulator to the old web W1 is blocked, and the old web W1 in the splicing device S is not in tension.
 続いて、図1Gに示すように、下側貼り付けロール2がさらに上昇(例えば、25mm上昇)すると共に、上側貼り付けロール1が下降(例えば、20mm)し、両ロール1、2が旧ウエブW1を介在して接圧(ニップ)する。この接圧時、下側貼り付けロール2は弾性表面の上側貼り付けロール1に、例えば2mm食い込んで、旧ウエブW1を確実にニップする。この作用と同時、又は後に、待機位置用バキュームボックス13への吸気を停止する。下側貼り付けロール2も弾性表面とすることができ、また、下側貼り付けロール2のみを弾性表面とすることもできる。 Subsequently, as shown in FIG. 1G, the lower application roll 2 is further raised (for example, 25 mm), the upper application roll 1 is lowered (for example, 20 mm), and both rolls 1 and 2 are connected to the old web. Contact pressure (nip) is performed through W1. At the time of this contact pressure, the lower application roll 2 bites into the upper application roll 1 having an elastic surface, for example, by 2 mm, and securely nips the old web W1. At the same time or after this action, the intake to the standby position vacuum box 13 is stopped. The lower application roll 2 can also be an elastic surface, and only the lower application roll 2 can be an elastic surface.
 上記両ロール1、2の接圧と同時、又はその接圧後、図1Hに示すように、上記旧ウエブW1の切断保持用バキュームボックス5、5が吸気されてその間の旧ウエブW1を支持固定するとともに、切断刃6によってその旧ウエブW1を切断する。
 このとき、その切断線の両側の旧ウエブW1を吸気して支持しているため、その切れ端が垂れ下がることなく、その切断が円滑に成される。切断が円滑でないと、その切断時間が長くなると共に、後述の新ウエブW2の先端縁との突き合わせがうまくいかない。また、その切断部分の前後の旧ウエブW1を吸着支持しているため、前記両ロール1、2の旧ウエブW1を介在した接圧はその旧ウエブW1の切断後でも良い。この切断した縁片は適宜に除去する。
 なお、その切断点の両ロール1、2の接圧点aからの距離は、その接圧点aから上側貼り付けロール1の接合テープT1の幅方向中心点までのロール周長(接圧点aから下側貼り付けロール2の接合テープT1の幅方向中心点までのロール周長)とほぼ同じに設定されている。
Simultaneously with or after the contact pressure between the rolls 1 and 2, as shown in FIG. 1H, the cutting and holding vacuum boxes 5 and 5 of the old web W1 are sucked and the old web W1 is supported and fixed therebetween. At the same time, the old web W1 is cut by the cutting blade 6.
At this time, since the old web W1 on both sides of the cutting line is sucked and supported, the cutting is smoothly performed without the cut ends hanging down. If the cutting is not smooth, the cutting time becomes long and the butting with the leading edge of the new web W2 described later is not successful. Further, since the old web W1 before and after the cut portion is adsorbed and supported, the contact pressure through the old web W1 of both the rolls 1 and 2 may be after the old web W1 is cut. The cut edge piece is appropriately removed.
In addition, the distance from the contact pressure point a of both rolls 1 and 2 of the cutting point is the roll circumference (contact pressure point) from the contact pressure point a to the center point in the width direction of the bonding tape T1 of the upper adhesive roll 1 It is set to be substantially the same as the roll circumferential length from a to the center point in the width direction of the joining tape T1 of the lower application roll 2.
 旧ウエブW1の切断が完了すれば、図1Iに示すように、上記切断保持用バキュームボックス5、5への吸気を停止し、ロータリーアクチュエータ12によって下側貼り付けロール2をウエブ送り出し方向(図1Iにおいて時計回り)に回転させる。例えば、180度回転させ、この回転に伴い、上側貼り付けロール1も反時計回りに回転する。
 この下側貼り付けロール2の回転時、上記切断保持用バキュームボックス5の吸気力は、旧ウエブW1の移動に支障がない程度であるため、バキュームボックス5への吸気を停止しなくてもよい。この場合は、旧ウエブW1がバキュームボックス5から離れた時点の後、その吸気を停止する。
When the cutting of the old web W1 is completed, as shown in FIG. 1I, the suction to the cutting and holding vacuum boxes 5 and 5 is stopped, and the lower adhesive roll 2 is moved in the web feed direction by the rotary actuator 12 (FIG. 1I). Rotate clockwise). For example, it is rotated 180 degrees, and with this rotation, the upper application roll 1 also rotates counterclockwise.
When the lower application roll 2 is rotated, the suction force of the cutting and holding vacuum box 5 is such that the movement of the old web W1 is not hindered, so that the suction to the vacuum box 5 does not have to be stopped. . In this case, after the old web W1 leaves the vacuum box 5, the intake is stopped.
 この下側貼り付けロール2の回転に伴い、両ロール1、2は接圧しているため、図3(a)から同(b)に示すように、ウエブW1及び新ウエブW2もそのロール1、2の回転によって送り出される(図1J右方に走行する)。このとき、上記ウエブW1の切断点の両ロール1、2の接圧点aからの距離は、その接圧点aから下側貼り付けロール2の接合テープT1の幅方向中心点までのロール周長とほぼ同じに設定されているため、旧ウエブW1の後端(切断端)と新ウエブW2の先端が突き合って接続した状態となる。 Since both rolls 1 and 2 are in contact pressure with the rotation of the lower application roll 2, as shown in FIGS. 3A to 3B, the web W1 and the new web W2 also have the roll 1, It is sent out by the rotation of 2 (runs to the right in FIG. 1J). At this time, the distance between the cutting point of the web W1 and the contact pressure point a of both rolls 1 and 2 is the roll circumference from the contact pressure point a to the center point in the width direction of the joining tape T1 of the lower application roll 2. Since it is set to be substantially the same as the length, the rear end (cut end) of the old web W1 and the front end of the new web W2 are in contact with each other.
 このウエブW1の後端(切断端)と新ウエブW2の先端が突き合い、さらに、両ロール1、2が回転すると、図3(c)に示すように、新ウエブW2の先端に貼着された接合テープT2の前半分が旧ウエブW1の後端下面に貼着されるとともに、上側貼り付けロール1に吸着されていた接合テープT1が新ウエブW2の先端及び旧ウエブW1の表面に前記突き合わせ線を境にして前後に貼着される。このため、この両接合テープT1、T2によって新旧のウエブW1、W2が接合・継ぎ合わせされる(図1J)。
 このとき、その両ウエブW1、W2の突き合わせ部分はピッタリでなくても、接合テープT1、T2がウエブW1、W2に亘って貼着される間隙があってもよい。この場合、上記ウエブW1の切断点の両ロール1、2の接圧点aからの距離と、その接圧点aから下側貼り付けロール2の接合テープT1の幅方向中心点までのロール周長とはその間隙(間隔)分、どちらかが短くなったり、上記上側貼り付けロール1の回転位置θ1及び下側貼り付けロール2の回転位置θ2が上記(θ1:137.5、θ2:68.5)に対してずれて設定されることとなったりするが、接合テープT1、T2の長さはその間隙が生じても旧ウエブW1の切断端又は新ウエブW2の先端に必ず接着するように設定する。
When the rear end (cut end) of the web W1 and the leading end of the new web W2 abut each other and both the rolls 1 and 2 rotate, as shown in FIG. 3C, the web W1 is adhered to the leading end of the new web W2. The front half of the joining tape T2 is adhered to the lower surface of the rear end of the old web W1, and the joining tape T1 adsorbed to the upper attaching roll 1 is abutted against the front end of the new web W2 and the surface of the old web W1. Affixed to the front and back of the line. For this reason, the old and new webs W1, W2 are joined and joined together by the joining tapes T1, T2 (FIG. 1J).
At this time, the abutting portions of both the webs W1, W2 may not be perfect, but there may be a gap where the joining tapes T1, T2 are stuck across the webs W1, W2. In this case, the distance between the cutting point of the web W1 from the contact pressure point a of both rolls 1 and 2, and the roll circumference from the contact pressure point a to the center point in the width direction of the joining tape T1 of the lower application roll 2 The length is shorter by the gap (interval), or the rotation position θ1 of the upper application roll 1 and the rotation position θ2 of the lower application roll 2 are the above (θ1: 137.5, θ2: 68). .5), the lengths of the joining tapes T1 and T2 should always be adhered to the cut end of the old web W1 or the front end of the new web W2 even if the gap is generated. Set to.
 この新旧ウエブW1、W2の継ぎ合わせ(スプライス)が完了すれば、上下の貼り付けロール1、2の吸気を停止するとともに、下側貼り付けロール2を反転(図1Kにおいて反時計回り)させて、例えば、180度反転させ、新ウエブW2を巻出側に送り戻して弛みをとる。
 この後、上記ストッパ19が後退して旧ウエブW1の接圧(走行停止)を開放し、この装置S内のウエブW1、W2の走行が可能となって次段のアキューム装置に送り出される。この作用に伴って、上下の貼り付けロール1、2を昇降させるとともに、待機位置用バキュームボックス13を下降させる(図1L)。
When the splicing of the new and old webs W1 and W2 is completed, the suction of the upper and lower application rolls 1 and 2 is stopped and the lower application roll 2 is reversed (counterclockwise in FIG. 1K). For example, it is reversed 180 degrees, and the new web W2 is sent back to the unwinding side to remove slack.
Thereafter, the stopper 19 moves backward to release the contact pressure (travel stop) of the old web W1, and the webs W1 and W2 in the apparatus S can travel and are sent to the next stage accumulator. With this action, the upper and lower sticking rolls 1 and 2 are raised and lowered, and the standby position vacuum box 13 is lowered (FIG. 1L).
 なお、以上の一連の作用において、昇降ロール15は、適宜に、上昇して新ウエブW2を所要高さで支持し、垂れ下がることを防止する。このため、下側貼り付けロール2への新ウエブW2の吸着力を低くしても剥がれることはない。吸着力を高くすると、剥がれにくくなるが、剥がれにくいと、後の接合テープT1、T2による接合部分の移行(ロール1、2から離れる作用)がうまくいかなくなる。このため、その作用が円滑に行われるようにその吸着力を適宜に設定する。
 切断した旧ウエブW1は、適宜な時期に、二軸ターレット自動巻き出し装置によって適宜に巻き取る。この実施形態においては、図1Iの時期に巻き取った。
In the above series of actions, the lifting roll 15 is appropriately lifted to support the new web W2 at the required height and prevent it from sagging. For this reason, even if the adsorption | suction power of the new web W2 to the lower side sticking roll 2 is made low, it does not peel off. If the adsorption force is increased, it will be difficult to peel off, but if it is difficult to peel off, the transition of the joined portion (the action of separating from the rolls 1 and 2) by the subsequent joining tapes T1 and T2 will not be successful. For this reason, the attracting force is appropriately set so that the action is smoothly performed.
The cut old web W1 is appropriately wound by a biaxial turret automatic unwinding device at an appropriate time. In this embodiment, the film was wound at the time shown in FIG.
 以上で、この装置Sによる新旧ウエブW1、W2の継ぎ合わせ作用は完了し、二軸ターレット自動巻き出し装置の新巻出軸と旧巻出軸が上下に反転して、前者が旧巻出軸、後者が新巻出軸となって、その旧巻出軸から上記新ウエブW2が繰り出されてこの装置S内を走行してアキューム装置に送り込まれる。このとき、図1Lに示すように、昇降ロール15が上昇して新ウエブW2が下側貼り付けロール2や待機位置用バキュームボックス13に干渉しないようになっているため、二軸ターレット自動巻き出し装置による巻出軸の交換は円滑に行われる。 Thus, the joining operation of the new and old webs W1 and W2 by the device S is completed, the new unwinding shaft and the old unwinding shaft of the biaxial turret automatic unwinding device are turned upside down, and the former is the old unwinding shaft. The latter becomes a new unwinding shaft, and the new web W2 is unwound from the old unwinding shaft, travels in the device S, and is fed into the accumulator device. At this time, as shown in FIG. 1L, the lifting roll 15 is raised so that the new web W2 does not interfere with the lower pasting roll 2 and the standby position vacuum box 13, so that the biaxial turret automatic unwinding The unwinding shaft is exchanged smoothly by the apparatus.
 以後、同様な作用が行われてウエブWが自動的に継ぎ合わされてアキューム装置等を介して洗浄装置等の次工程に連続的に送り込まれる。
 この実施形態では、ウエブWの継ぎ時間のためにウエブWの走行を停止した時間は、3~4.5秒であったが、上記特許文献1の従来の装置にあっては、同一のウエブWにおいて、同12~13秒を要した。
 なお、新旧ウエブW1、W2の継ぎ合わせ作用は、図1Jの段階で終了するため、後段工程によって継ぎ合わせ時の新ウエブW2の弛みが吸収できれば、上記図1K、同Lの作用は省略し得る。
Thereafter, the same operation is performed, and the web W is automatically spliced and continuously fed to the next process of the cleaning device or the like via the accumulator device or the like.
In this embodiment, the traveling time of the web W due to the splicing time of the web W was 3 to 4.5 seconds. However, in the conventional apparatus of Patent Document 1, the same web is used. In W, it took 12 to 13 seconds.
Since the joining operation of the new and old webs W1, W2 ends at the stage of FIG. 1J, the action of FIG. 1K, L can be omitted if the slack of the new web W2 at the time of joining can be absorbed by the subsequent process. .
 上記実施形態においては、上下の貼り付けロール1、2に接合テープT1、T2を吸着するようにしたが、その接合テープT1、T2の吸着はその両ロール1、2の一方のみでも良い。上側貼り付けロール1に接合テープT1を吸着させれば、図3(c)において、両ウエブW1、W2の上面に接合テープT1のみが貼着された継ぎ目となり、下側貼り付けロール2に接合テープT2を吸着させれば、図3(c)において、両ウエブW1、W2の下面に接合テープT2のみが貼着された継ぎ目となる。 In the above embodiment, the bonding tapes T1 and T2 are adsorbed to the upper and lower affixing rolls 1 and 2, but the adhering of the bonding tapes T1 and T2 may be performed by only one of the two rolls 1 and 2. If the bonding tape T1 is adsorbed to the upper adhesive roll 1, in FIG. 3C, only the bonding tape T1 is adhered to the upper surfaces of both webs W1 and W2, and the adhesive tape T1 is bonded to the lower adhesive roll 2. If the tape T2 is adsorbed, in FIG. 3C, a seam is obtained in which only the bonding tape T2 is adhered to the lower surfaces of both webs W1, W2.
 また、下側貼り付けロール2に表裏両面が貼着面となった両面接合テープT3を吸着させれば、図4に示すように、旧ウエブW1の後端と新ウエブW2の先端の間に接合テープT3が介在された継ぎ目となる。このとき、両ウエブW1、W2の端が重なるように、下側貼り付けロール2の接合テープT3の吸着面2aはその重なり分(例えば、接合テープT3の長さ半分以上)、時計方向に所要角度進めた位置としたり、旧ウエブW1の切断点をさらに前段としたりして、両ロール1、2の接圧点aからから下側貼り付けロール2の接合テープT3の幅方向中心点までのロール周長に対し、旧ウエブW1の切断点の両ロール1、2の接圧点aからの距離を長くする。
 なお、この両面接合テープT3の場合は、接合テープT2が新ウエブW2の下表面に貼着されたが(図3(c)参照)、図4に示すように、新ウエブW2の上表面に貼着される。
Moreover, if the double-sided bonding tape T3 with both front and back surfaces being attached surfaces is adsorbed to the lower application roll 2, as shown in FIG. 4, between the rear end of the old web W1 and the front end of the new web W2. It becomes a joint where the joining tape T3 is interposed. At this time, the adsorbing surface 2a of the joining tape T3 of the lower application roll 2 is required in the clockwise direction so that the ends of both webs W1 and W2 overlap each other (for example, more than half the length of the joining tape T3). From the contact pressure point a of both rolls 1 and 2 to the center point in the width direction of the joining tape T3 of the lower application roll 2 with the angle advanced position or the cutting point of the old web W1 further upstream The distance between the cutting point of the old web W1 and the contact pressure point a of both rolls 1 and 2 is increased with respect to the roll circumference.
In the case of this double-sided bonding tape T3, the bonding tape T2 was adhered to the lower surface of the new web W2 (see FIG. 3C), but as shown in FIG. Affixed.
 図5A、同F、同J、同Lに他の実施形態を示し、この実施形態の継ぎ装置Sは、上記実施形態において、昇降ロール15、転移ロール16を省略し、上記ロール回転ストッパ19をエアシリンダ21によって揺動する揺動片22に取り付け、その揺動片22に別個に送り出しロール23を設け、上記送り出しロール18を案内ロールとしたものである。また、下側貼り付けロール2は駆動機が付設されて回転し、その回転をブレーキロール24で許容したり停止したりする。図5各中、上記と同一符号は同一物を示し、その作用は、図5Aは図1A、図5Fは図1F・・にそれぞれ対応し、省略した作用(図)は図1B~同E、同G、同H、同I、同Kとほぼ同様である。 FIGS. 5A, 5F, 5J, and 5L show other embodiments. In the above-described embodiment, the splicing device S according to this embodiment omits the lifting roll 15 and the transfer roll 16, and the roll rotation stopper 19 is used. It is attached to a rocking piece 22 that is rocked by an air cylinder 21, and a separate feed roll 23 is provided on the rocking piece 22, and the feed roll 18 is used as a guide roll. Further, the lower application roll 2 rotates with a driving machine attached, and the rotation is allowed or stopped by the brake roll 24. In FIG. 5, the same reference numerals as those described above denote the same components, and the operation thereof corresponds to FIG. 1A in FIG. 5A, FIG. 5F corresponds to FIG. Same as G, H, I and K.
 この実施形態の継ぎ装置Sにおける上記実施形態の作用との相違点は、まず、図5Aに示すように、新ウエブW2を下側貼り付けロール2に接合テープT2を介在して直接に吸着させる。このとき、接合テープT2はその貼着面でその幅方向半分が新ウエブW2に貼着され、その残りの貼着面は上面に露出する。
 因みに、上記実施形態においては、転移ロール16に新ウエブW2を吸着した後、その端縁に接合テープT2を吸着し、それを下側貼り付けロール2に転移させるため、前記接合テープT2はその貼着面でその幅方向半分が新ウエブW2に貼着され、その残りの貼着面は上面に露出した状態となる。
 つぎに、その接合テープT2の貼着後又は前に、上側貼り付けロール1に接合テープT1を吸着させ、以後同様な作用が行われ、図5Fに示すように、ロール回転ストッパ19によって旧ウエブW1の走行を停止させる。続いて、上下側の貼り付けロール1、2が昇降し、その両ロール1、2でもって旧ウエブW1をニップし、この状態において、旧ウエブW1が切断刃6により切断される。
The difference from the operation of the above-described embodiment in the splicing device S of this embodiment is that, as shown in FIG. 5A, first, the new web W2 is directly adsorbed to the lower application roll 2 via the joining tape T2. . At this time, the bonding tape T2 has its sticking surface half pasted in the width direction on the new web W2, and the remaining sticking surface is exposed on the top surface.
Incidentally, in the above embodiment, after adsorbing the new web W2 to the transfer roll 16, the adhering tape T2 is adsorbed to the edge thereof and transferred to the lower application roll 2, so that the adjoining tape T2 is Half of the width direction is stuck on the new web W2 on the sticking surface, and the remaining sticking surface is exposed on the top surface.
Next, after the bonding tape T2 is attached or before, the bonding tape T1 is adsorbed to the upper application roll 1, and thereafter the same action is performed. As shown in FIG. Stop running W1. Subsequently, the upper and lower application rolls 1 and 2 are moved up and down, and the old web W1 is nipped by both rolls 1 and 2, and the old web W1 is cut by the cutting blade 6 in this state.
 切断が完了すれば、図5Jに示すように、揺動片22がエアシリンダ21によって後方に揺動(回転)して、送り出しロール23を介して旧ウエブW1を引き出す。このとき、ブレーキロール24は開放されているため、その旧ウエブW1の引き出しにともなって両貼り付けロール1、2が回転する。この回転に伴い、ウエブW1及び新ウエブW2も送り出され(図5J右方に走行し)、ウエブW1の後端と新ウエブW2の先端が突き合って接続した状態となるとともに、両接合テープT1、T2が新ウエブW2の先端及び旧ウエブW1の表面に前記突き合わせ線を介して前後に貼着され、この両接合テープT1、T2によって新旧のウエブW1、W2が接合・継ぎ合わせされる(図5J、図3(c))。
 この新旧ウエブW1、W2の継ぎ合わせ(スプライス)が完了すれば、図5Lに示すように、揺動片22を前方に揺動(回転)させて、通常のウエブWの送り出し作用に移行する。
When the cutting is completed, as shown in FIG. 5J, the swing piece 22 swings back (rotates) by the air cylinder 21, and the old web W1 is pulled out via the feed roll 23. Since the brake roll 24 is open | released at this time, both the sticking rolls 1 and 2 rotate with the drawer | drawing-out of the old web W1.
