The portion can be easily formed while being intermittently and accurately interposed in the moving direction, and the productivity of the sheet detergent can be improved.

　本発明の好ましい実施形態について説明する。表裏一対のシートの周縁部をシールして形成した平面が矩形状の平坦な袋に、流動性物質としてのドウ状洗剤を収容したシート状洗剤包装体を量産する際に、後述する間欠敷設方法及び間欠敷設装置を採用した。図１に示す間欠敷設装置１０を用いて一方向に連続供給されてコンベア１１によって流れるように移動する帯状の裏面シート１２の表面に、ドウ状洗剤１３からなる塗布層（敷設層）１４を、移動方向Ｘに非塗布部（非敷設部）１５を介在させつつ間欠的に形成する。なお「ドウ」とは、特開平１０−２０４４９９号公報に記載されるように、粉末組成物と液体、ペースト、ゲル等の流動性を有する物質との捏和物をいい、流動性を有する物質は加熱や応力により流動化するものも含まれる。 好 ま し い A preferred embodiment of the present invention will be described. When mass-producing a sheet-like detergent package containing a dough-like detergent as a flowable substance in a flat, rectangular bag formed by sealing the peripheral edges of a pair of front and back sheets, an intermittent laying method described later is used. And an intermittent laying device. A coating layer (laying layer) 14 made of a dough-like detergent 13 is provided on the surface of a belt-like back sheet 12 which is continuously supplied in one direction using an intermittent laying apparatus 10 shown in FIG. It is formed intermittently with a non-coating portion (non-laying portion) 15 interposed in the moving direction X. As described in JP-A-10-204499, "dough" refers to a kneaded product of a powder composition and a substance having fluidity such as liquid, paste, and gel, and a substance having fluidity. Include those which are fluidized by heating or stress.

　非塗布部１５を介在させつつ配置した塗布層１４の表面に次の工程で図４に示す方法と同様に表面シートを配した後、非塗布部１５において表裏のシートをシールし、シール部を適宜切断分割して、表裏一対のシートからなる矩形状の平坦な袋にドウ状洗剤が収容されたシート状洗剤包装体を得る。 After arranging a surface sheet on the surface of the coating layer 14 disposed with the non-coating section 15 therebetween in the next step in the same manner as the method shown in FIG. By appropriately cutting and dividing, a sheet-like detergent package in which a dough-like detergent is contained in a rectangular flat bag composed of a pair of front and back sheets is obtained.

　本実施形態におけるドウ状洗剤１３は、敷設手段としての塗布ヘッド１６を介して裏面シート１２の表面に塗布することが可能な流動性及び可塑性を備えるペースト状の洗剤であって、粘稠性を有し、また崩れたり流出したりすることなく層状に塗布された状態を保持する保形性を備える。また、裏面シート１２及び表面シートは、例えばポリビニルアルコール系繊維からなる繊維シートや、各種の水溶性フィルムによって構成される。したがって、洗濯機による洗濯の際に、シール部を切断して個々に分割したシート状洗剤包装体を洗濯槽内に所定個数投入すれば、ドウ状洗剤１３を覆う表裏のシートが速やかに溶解して、包装されていたドウ状洗剤１３が洗濯水中に容易に溶解する。 The dough detergent 13 in the present embodiment is a paste detergent having fluidity and plasticity that can be applied to the surface of the back sheet 12 via an application head 16 as a laying means. It has a shape-retaining property of maintaining a state of being applied in a layered form without collapsing or flowing out. Further, the back sheet 12 and the top sheet are made of, for example, a fiber sheet made of polyvinyl alcohol-based fibers or various water-soluble films. Therefore, at the time of washing by a washing machine, if a predetermined number of sheet-like detergent packages that are cut and individually divided into seal portions are put into a washing tub, the front and back sheets covering the dough-like detergent 13 are quickly dissolved. Thus, the packaged dough detergent 13 is easily dissolved in the washing water.

　本実施形態によれば、間欠敷設装置１０は、ドウ状洗剤１３を裏面シート１２に塗布する塗布ヘッド１６と、塗布ヘッド１６の上流側に配置される裏面シート１２の折り込み手段１７と、塗布ヘッド１６の下流側に配置される折り込み解除手段１８とを備える。 According to the present embodiment, the intermittent laying device 10 includes a coating head 16 for applying the dough detergent 13 to the back sheet 12, a folding unit 17 for the back sheet 12 disposed upstream of the coating head 16, And folding release means 18 disposed downstream of the folding means 16.

　折り込み手段１７は、コンベア１１によって移動する裏面シート１２の移動方向Ｘに所定の間隔（例えば７０ｍｍ）をおいてコンベア１１の表面に複数形成された、移動方向Ｘと垂直な方向に延長する押し込み溝としてのピン挿入溝１９と、移動方向Ｘにピン挿入溝１９と同速度で移動し、移動方向Ｘへの移動時における中心軸の高さがピン挿入溝１９の中心の高さと略一致するように配されることにより、ピン挿入溝１９に沿って各々挿入される挿入部材としての複数のピン部材２０と、コンベア１１を方向転換させて移動方向Ｘに案内する上流側ロール部材２１とによって構成される。押し込み溝の機能としては、シートを支える離間した２つの押し込み溝の縁部と２つの押し込み溝の縁部に挟まれた空間があればよく、例えば細棒を２本並べることでも構成できる。また、押し込み溝の縁部は後述するように流動性物質を敷設する際は近づいてシートの表面を実質的に連続にする。挿入部材はこの離間した２つの縁部の間にシートの一部を押し込む為のものである。 The folding means 17 includes a plurality of push grooves formed on the surface of the conveyor 11 at predetermined intervals (for example, 70 mm) in the movement direction X of the back sheet 12 moved by the conveyor 11 and extending in a direction perpendicular to the movement direction X. And the pin insertion groove 19 moves in the movement direction X at the same speed as the pin insertion groove 19, and the height of the center axis at the time of movement in the movement direction X is substantially equal to the height of the center of the pin insertion groove 19. , A plurality of pin members 20 as insertion members each inserted along the pin insertion groove 19, and an upstream roll member 21 that changes the direction of the conveyor 11 and guides the conveyor 11 in the movement direction X. Is done. The function of the pushing groove is sufficient if there is a space between the edges of the two pushing grooves that support the sheet and a space between the edges of the two pushing grooves. For example, two push rods can be arranged. In addition, as described later, the edge of the pushing groove approaches when the fluid substance is laid, and makes the surface of the sheet substantially continuous. The insertion member is for pushing a part of the sheet between the two separated edges.

　ピン挿入溝１９は、図２（ａ）に示すように、コンベア１１のベルト本体２２の表面に、厚さが例えば５ｍｍのウレタンからなるスポンジ板２３を、例えば５ｍｍ程度の隙間を設けつつ密着配置することにより、当該隙間によって例えば幅が５ｍｍ、深さが５ｍｍの大きさで設ける。また、スポンジ板２３の表面は、厚さが例えば０．２ｍｍのポリエチレンテレフタレート（ＰＥＴ）フィルムからなる保護膜プレート２４で覆われていると共に、この保護膜プレート２４の端部が、ピン挿入溝１９の表面開口部に縁部として張り出していることにより、ピン挿入溝１９の開口幅ｋが０．２ｍｍ程度となっている。 As shown in FIG. 2A, the pin insertion groove 19 is formed by closely attaching a sponge plate 23 made of urethane having a thickness of, for example, 5 mm to the surface of the belt body 22 of the conveyor 11 while providing a gap of, for example, about 5 mm. By doing so, the gap is provided with a size of, for example, 5 mm in width and 5 mm in depth. The surface of the sponge plate 23 is covered with a protective film plate 24 made of, for example, a polyethylene terephthalate (PET) film having a thickness of 0.2 mm, for example. , The opening width k of the pin insertion groove 19 is about 0.2 mm.

　なお、スポンジ板２３は、上流側ロール部材２１上での方向転換時において、ベルト本体２２からの剥離が抑制される程度の柔軟な材質を備えるものである。また、保護膜プレート２４は、裏面シート１２を折り込む際に、ピン挿入溝１９のピン部材２０を挿入できる程度に変形可能な弾性を備えるものである。 The sponge plate 23 is made of a material that is flexible enough to prevent peeling from the belt body 22 when the direction is changed on the upstream roll member 21. The protective film plate 24 has elasticity that can be deformed to the extent that the pin member 20 of the pin insertion groove 19 can be inserted when the back sheet 12 is folded.

　ピン部材２０は、直径が例えば３ｍｍの丸鋼であって、その両端にベアリング２５が取り付けられている（図１参照）。また、コンベア１１を挟んだ両側には、ピン搬送系を構成する一対のピンガイドレール２６が設置されていて、各ピンガイドレール２６に沿ってベアリング２５を各々転動させることにより、各ピン部材２０を、コンベア１１と同速度で且つ中心軸の高さがピン挿入溝１９の中心の高さと略一致するようにしつつ、移動方向Ｘに移動させることができる。さらに、ピン部材２０は、ピンガイドレール２６に沿って、ピン挿入溝１９と同じピッチ（例えば７０ｍｍ）で配設されることにより、移動方向Ｘにおいて、複数のピン挿入溝１９にピン部材２０を各々同時に挿入配置することができる。 The pin member 20 is a round steel having a diameter of, for example, 3 mm, and bearings 25 are attached to both ends thereof (see FIG. 1). Further, a pair of pin guide rails 26 constituting a pin transport system are installed on both sides of the conveyor 11, and by rolling the bearings 25 along each pin guide rail 26, each pin member is moved. 20 can be moved in the movement direction X at the same speed as the conveyor 11 and with the height of the central axis substantially matching the height of the center of the pin insertion groove 19. Further, the pin members 20 are arranged at the same pitch (for example, 70 mm) as the pin insertion grooves 19 along the pin guide rails 26, so that the pin members 20 are inserted into the plurality of pin insertion grooves 19 in the movement direction X. Each can be inserted and arranged simultaneously.

　上流側ロール部材２１は、直径が例えば１２５ｍｍの円筒状の部材であって、後述する下流側ロール部材２７との間にコンベア１１を巻回し、駆動モータの駆動力によってコンベア１１を所定の速度で無端状に回動させる。また、上流側ロール部材２１は、下方を移動しているコンベア１１を上方に方向転換させる際に、その外周面の曲率によって、図２（ｂ）に示すようにピン挿入溝１９の開口幅ｋを拡幅し、すなわち押し込み溝の縁を離間させ、また外周面から移動方向Ｘにコンベア１１を移行させる際に、ピン挿入溝１９の開口幅を再び狭め押し込み溝の縁を近づける（図２（ｄ）参照）。 The upstream roll member 21 is a cylindrical member having a diameter of, for example, 125 mm. The upstream roll member 21 winds the conveyor 11 between the downstream roll member 27 described below, and drives the conveyor 11 at a predetermined speed by the driving force of a driving motor. Rotate endlessly. Further, when the upstream roll member 21 changes the direction of the conveyor 11 moving downward, the opening width k of the pin insertion groove 19 as shown in FIG. When the conveyor 11 is moved in the moving direction X from the outer peripheral surface, that is, when the conveyor groove 11 is moved away from the outer peripheral surface, the opening width of the pin insertion groove 19 is narrowed again to bring the edge of the push groove closer (FIG. 2 (d)). )reference).

　そして、本実施形態によれば、ピン挿入溝１９が上流側ロール部材２１の外周面に位置してその開口幅ｋが広がった状態から（図２（ｂ）参照）、この外周面を通過して開口幅ｋが狭まった状態に移行する際に（図２（ｄ）参照）、図２（ｃ）に示すように、シート供給ロール２８（図１参照）から連続的に巻出し供給される裏面シート１２を挟み込みつつ、張り出した保護膜プレート２４の弾性に抗してピン部材２０をピン挿入溝１９に挿入することによって、非塗布部１５に対応する裏面シート部材１２の一部を、当該裏面シート部材１２の裏面側に折り込む。 Then, according to the present embodiment, the pin insertion groove 19 is located on the outer peripheral surface of the upstream-side roll member 21 and the opening width k is widened (see FIG. 2B). When the opening width k shifts to a narrowed state (see FIG. 2D), as shown in FIG. 2C, the sheet is continuously unwound and supplied from the sheet supply roll 28 (see FIG. 1). By inserting the pin member 20 into the pin insertion groove 19 against the elasticity of the overhanging protective film plate 24 while sandwiching the back sheet 12, a part of the back sheet member 12 corresponding to the non-applied portion 15 is removed. It is folded into the back side of the back sheet member 12.

　また、ピン部材２０を介して裏面シート１２がピン挿入溝１９に折り込まれる際に、上流側ロール部材２１の外周面において拡幅していた保護膜プレート２４の先端と隣接するスポンジ板２３との間の開口幅ｋは、シート供給ロール２８の外周面から移動方向Ｘに移行しつつ再び狭められることにより（図２（ｄ）参照）、一対の上流側及び下流側の押し込み溝の縁部が近づき、結果として裏面シート１２の折り込み縁部２９は互いに近接することになるので、裏面シート１２の表面側には、塗布ヘッド１６からドウ状洗剤１３を塗布するための連続的な被塗布面（被敷設面）３０が形成される。この被塗布面３０には、図１及び図２（Ｅ）に示すように、ドウ状洗剤１３が塗布ヘッド１６から連続的に塗布される。 Further, when the back sheet 12 is folded into the pin insertion groove 19 via the pin member 20, the gap between the front end of the protective film plate 24, which has widened on the outer peripheral surface of the upstream roll member 21, and the adjacent sponge plate 23. Is narrowed again while moving in the movement direction X from the outer peripheral surface of the sheet supply roll 28 (see FIG. 2D), so that the edges of the pair of upstream and downstream push grooves approach each other. As a result, the folded edges 29 of the back sheet 12 come close to each other, so that a continuous coating surface (coating surface) for applying the dough detergent 13 from the coating head 16 is applied to the front side of the back sheet 12. A laying surface) 30 is formed. As shown in FIGS. 1 and 2E, the dough-like detergent 13 is continuously applied from the application head 16 to the surface 30 to be applied.

　ここで、本実施形態によれば、ピン部材２０の中心軸の高さがピン挿入溝１９の中心の高さと略一致した状態で、各ピン部材２０はピン挿入溝１９に挿入配置されるが、ピン部材２０のピン挿入溝１９内における高さ方向の位置や横方向の位置を調整することにより、ピン部材２０によって挟み込まれる裏面シート１２の折り込み量を増減して、後述する非塗布部１５の幅を容易に調整できる。かかるピン部材２０のピン挿入溝１９内における位置の調整は、例えばコンベア１１が巻回される上流側ロール部材２１及び下流側ロール部材２７と、ピン部材２０に取り付けられたベアリング２５を案内するピンガイドレール２６との相対位置を制御することにより、容易に行うことができる。また、ピン部材２０の径の大きさを変更することによっても、ピン部材２０によって挟み込まれる裏面シート１２の折り込み量を増減して、非塗布部１５の幅を容易に調整できる。 Here, according to the present embodiment, each pin member 20 is inserted and arranged in the pin insertion groove 19 in a state where the height of the center axis of the pin member 20 substantially matches the height of the center of the pin insertion groove 19. By adjusting the height position and the horizontal position of the pin member 20 in the pin insertion groove 19, the amount of folding of the back sheet 12 sandwiched by the pin member 20 is increased or decreased, and the Can be easily adjusted. The position of the pin member 20 in the pin insertion groove 19 is adjusted, for example, by a pin for guiding the upstream roll member 21 and the downstream roll member 27 around which the conveyor 11 is wound and the bearing 25 attached to the pin member 20. By controlling the relative position with respect to the guide rail 26, it can be easily performed. Also, by changing the diameter of the pin member 20, the amount of folding of the back sheet 12 sandwiched by the pin member 20 can be increased or decreased, and the width of the non-applied portion 15 can be easily adjusted.

　なお、本実施形態によれば、上流側ロール部材２１の上方には、当該上流側ロール部材２１の上端部分を通過するコンベア１１と接するようにして、ピン押し込みロール３１を設けても良い。このピン押し込みロール３１によってピン部材２０を押さえつけることにより、ピン部材２０をピン挿入溝１９へ挿入することによる裏面シート１２の折り込みを、さらにスムースに行うことができるようになる。 According to the present embodiment, the pin pushing roll 31 may be provided above the upstream roll member 21 so as to be in contact with the conveyor 11 passing through the upper end portion of the upstream roll member 21. By pressing the pin member 20 by the pin pushing roll 31, the back sheet 12 can be more smoothly folded by inserting the pin member 20 into the pin insertion groove 19.

　一方、本実施形態によれば、折り込み解除手段１８は、コンベア１１を裏面シート１２の移動方向Ｘから下方に方向転換させる下流側ロール部材２７と、当該下流側ロール部材２７よりも下流側において、裏面シート部材１２を移動方向Ｘに引っ張る張力付与手段（図示せず）とによって構成される。 On the other hand, according to the present embodiment, the folding release means 18 includes the downstream roll member 27 that changes the direction of the conveyor 11 downward from the moving direction X of the back sheet 12, and the downstream roll member 27 downstream of the downstream roll member 27. It is constituted by tension applying means (not shown) for pulling the back sheet member 12 in the movement direction X.

　下流側ロール部材２７は、直径が例えば１２５ｍｍの上流側ロール部材２１と同様の円筒状の部材であって、移動方向Ｘに移動しているコンベア１１を下方に向けて方向転換させる際に、その外周面の曲率によって、図３に示すように、ピン挿入溝１９の開口幅ｋを拡幅すると共に、引き続き移動方向Ｘに沿って移動するピン部材２０がピン挿入溝１９から取り出されるようにして、非塗布部１５に位置する裏面シート１２の折り込み状態を解除する。 The downstream roll member 27 is a cylindrical member similar to the upstream roll member 21 having a diameter of, for example, 125 mm. When the conveyor 11 moving in the movement direction X is turned downward, By the curvature of the outer peripheral surface, as shown in FIG. 3, the opening width k of the pin insertion groove 19 is increased, and the pin member 20 that moves continuously in the movement direction X is taken out from the pin insertion groove 19. The folded state of the back sheet 12 located at the non-coating section 15 is released.

　張力付与手段は、例えば次工程であるシール工程にドウ状洗剤１３が塗布された裏面シート１２を送り出す送り出しローラ（図示せず）等からなり、その送り出し速度が、コンベア１１による移動方向Ｘへの裏面シート１２の移動速度よりも早くなっていることにより、裏面シート１２を移動方向Ｘの下流側に引っ張り、裏面シート１２の折り込み縁部２９，２９を離間させて、裏面シート１２の非塗布部１５を被塗布面３０と同一面に復帰させる（図３参照）。 The tension applying means includes, for example, a delivery roller (not shown) for delivering the back sheet 12 to which the dough detergent 13 has been applied in a sealing process as a next process. Since the moving speed of the back sheet 12 is higher than the moving speed of the back sheet 12, the back sheet 12 is pulled downstream in the moving direction X, the folded edges 29, 29 of the back sheet 12 are separated, and the uncoated portion of the back sheet 12 is moved. 15 is returned to the same surface as the coated surface 30 (see FIG. 3).

　また、本実施形態によれば、下流側ロール部材２７の上流側には、カッティ ング手段としてのカッテイングロール３２を、裏面シート１２の表面に連続塗布されて形成された塗布層１４の上方に配置している。カッテイングロール３２は、その円周の１／４の長さがピン挿入溝１９のピッチと同じ長さとなる大きさの円筒状の部材であって、その円周を４分割する位置に各々カッター３３を突出して設けてある。カッター３３は、裏面シート１２の非塗布部１５が折り込まれたピン挿入溝１９の直上部分に配置してあり、当該直上部分において、塗布面３０に連続的に塗布されたドウ状洗剤１３による塗布層１４に食い込んで、切れ目を形成する。カッテイングロール３２は、その周面の回転速度が、移動方向Ｘへのコンベアの移動速度と一致するように制御され、４箇所のカッター３３が、所定ピッチで配された複数の各ピン挿入溝１９の直上部分の塗布層１４に順次食い込んで、各々切れ目を形成する。 Further, according to the present embodiment, a cutting roll 32 as a cutting means is disposed on the upstream side of the downstream roll member 27 above the coating layer 14 formed by continuously coating the surface of the back sheet 12. are doing. The cutting roll 32 is a cylindrical member having a size such that a quarter of its circumference is the same as the pitch of the pin insertion grooves 19, and each of the cutters 33 is provided at a position where the circumference is divided into four. Are provided to protrude. The cutter 33 is disposed in a portion directly above the pin insertion groove 19 in which the non-coating portion 15 of the back sheet 12 is folded, and in the portion directly above, the coating by the dough detergent 13 continuously applied to the coating surface 30. It cuts into layer 14 to form a cut. The cutting roll 32 is controlled so that the rotational speed of the peripheral surface thereof matches the moving speed of the conveyor in the moving direction X, and the four cutters 33 are provided with a plurality of pin insertion grooves 19 arranged at a predetermined pitch. Are sequentially cut into the coating layer 14 immediately above the portions to form cuts.

　カッター３３によって、下流側ロール部材２７の上流側において連続的な塗布層１４に予め切れ目を形成しておくことにより、ピン挿入溝１９からピン部材２０を取り出しつつ裏面シート１２の折り込み縁部２９を離間させる際に、粘稠性を有するドウ状洗剤１３であっても当該ドウ状洗剤１３を切れ目を介して両側に容易に切り離すことができ、ドウ状洗剤１３が非塗布部１５にはみ出したり、ピン部材２０が取り出される際にドウ状洗剤１３が付着して当該ピン部材２０が汚れるのを容易に回避することが可能になる。 By forming a cut in the continuous coating layer 14 in advance on the upstream side of the downstream roll member 27 by the cutter 33, the folding edge 29 of the back sheet 12 is removed while removing the pin member 20 from the pin insertion groove 19. At the time of separation, even the dough detergent 13 having a viscous property, the dough detergent 13 can be easily cut off on both sides through cuts, and the dough detergent 13 protrudes into the non-application portion 15, When the pin member 20 is taken out, it is possible to easily prevent the dough-like detergent 13 from adhering and the pin member 20 from being soiled.

　なお、ドウ状洗剤１３をカッティングした後のカッター３３をブラシ、織布、不織布、エアー等により清掃するカッター汚れ除去手段（図示せず）を、カッティングロール３２に隣接して設けた。また、折り込み解除手段１８より下流側におけるピンガイドレール２６と隣接する位置には、ブラシ、織布、不織布、エアー等によりピン挿入溝１９から取り出されたピン部材２０を清掃するピン汚れ除去手段（図示せず）を設けた。 カ ッ タ ー A cutter dirt removing means (not shown) for cleaning the cutter 33 after cutting the doughy detergent 13 with a brush, woven cloth, nonwoven cloth, air or the like is provided adjacent to the cutting roll 32. Further, at a position adjacent to the pin guide rail 26 on the downstream side of the folding release means 18, a pin dirt removing means (for cleaning the pin member 20 taken out of the pin insertion groove 19 by a brush, a woven cloth, a nonwoven cloth, air or the like). (Not shown).

　非塗布部１５が折り込まれたピン挿入溝１９の直上部分において連続的な塗布層１４に予め切れ目を形成する他の方法としては、例えば、カッターが上下することにより切れ目を形成するレシプロ式のカッティング方法や、塗布層１４に食い込んだ後、塗布層１４の移動速度と共にカッターが一定時間塗布層１４に食い込んだ状態を維持することによって切れ面をより確実に形成する等速レシプロ式のカッティング方法、或いは塗布層１４の幅方向に対してカッターを移動することにより塗布層１４に切れ目を形成するトラバース式のカッティング方法を採用することもできる。 Another method of forming a cut in the continuous coating layer 14 immediately above the pin insertion groove 19 where the non-coating portion 15 is folded is, for example, a reciprocating cutting method in which a cut is formed by moving a cutter up and down. A method or a constant-speed reciprocating cutting method in which a cutting surface is more reliably formed by maintaining a state in which a cutter bites into the coating layer 14 for a certain period of time together with the moving speed of the coating layer 14 after biting into the coating layer 14, Alternatively, a traverse-type cutting method in which a cut is formed in the coating layer 14 by moving a cutter in the width direction of the coating layer 14 can be adopted.

　本実施形態によれば、上述の構成を有する間欠敷設装置１０を用いることにより、移動方向Ｘに連続供給されてコンベア１１によって移動する帯状の裏面シート１２の表面に、ドウ状洗剤１３からなる塗布層１４を、移動方向Ｘに間欠的に非塗布部１５を介在させつつ容易に形成できる。すなわち、まず塗布ヘッド１６の上流側において、非塗布部１５に位置する裏面シート１２を、ピン部材２０をピン挿入溝１９に挿入しつつ当該裏面シート１２の裏面側に折り込んで、連続的な被塗布面３０を裏面シート１２の表面側に形成する。次に被塗布面３０に塗布ヘッド１６からドウ状洗剤１３を連続的に供給して塗布層１４を形成した後、塗布ヘッド１６の下流側において裏面シート１２の折り込まれた非塗布部１５を塗布面３０と同一面に復帰させて、連続的に敷設したドウ状洗剤１３からなる塗布層１４の間に非塗布部１５を間欠的に介在させる。 According to this embodiment, by using the intermittent laying device 10 having the above-described configuration, the dough-like detergent 13 is applied to the surface of the belt-like back sheet 12 that is continuously supplied in the movement direction X and moves by the conveyor 11. The layer 14 can be easily formed while intermittently interposing the non-coating portion 15 in the moving direction X. That is, first, on the upstream side of the coating head 16, the back sheet 12 located at the non-coating portion 15 is folded into the back side of the back sheet 12 while the pin member 20 is inserted into the pin insertion groove 19, so that a continuous covering is performed. The application surface 30 is formed on the front side of the back sheet 12. Next, the dough-like detergent 13 is continuously supplied from the coating head 16 to the coating surface 30 to form the coating layer 14, and the folded non-coating portion 15 of the back sheet 12 is coated downstream of the coating head 16. The non-applied portion 15 is intermittently interposed between the application layers 14 made of the dough-like detergent 13 laid back on the same surface as the surface 30.

　なお、塗布ヘッド１６を、移動方向Ｘと直交する方向に隣接して一対設け、裏面シート１２に対して２列にドウ状洗剤１３を塗布する。一対の塗布ヘッド１６を所定の間隔をおいて配置することにより、２列の塗布層１４の間に移動方向Ｘに沿った縦方向の非塗布部１５を容易に形成でき、これによって塗布層１４を、縦横に非塗布部１５を介在させつつ裏面シート１２に２列に配置する。 (4) A pair of application heads 16 are provided adjacent to each other in a direction orthogonal to the moving direction X, and the dough detergent 13 is applied to the back sheet 12 in two rows. By arranging the pair of coating heads 16 at a predetermined interval, the non-coating portion 15 in the vertical direction along the moving direction X can be easily formed between the two rows of coating layers 14. Are arranged in two rows on the back sheet 12 with the non-coating portion 15 interposed vertically and horizontally.

　本実施形態によれば、塗布ヘッド１６によるドウ状洗剤１３の供給及び停止を所定の時間間隔毎に繰り返して塗布ヘッド１６を間欠制御することなく、塗布ヘッド１６によるドウ状洗剤１３の連続的な供給を維持したまま、裏面シート１２の流れに沿って裏面シート１２の折り込み及び折り込みの解除を繰り返すことによって非塗布部１５を間欠的に介在させるので、コンベア１１によって一方向に移動する帯状の裏面シート１２の表面に、ドウ状洗剤１３からなる塗布層１４を、非塗布部１５を移動方向Ｘに間欠的に精度良く介在させつつ容易に形成することが可能になり、シート状洗剤包装体の生産能力を向上させることができる。 According to the present embodiment, the supply and stop of the dough detergent 13 by the coating head 16 are repeated at predetermined time intervals, so that the dough detergent 13 is continuously applied by the coating head 16 without intermittent control of the coating head 16. While the supply is maintained, the non-coating portion 15 is intermittently interposed by repeatedly folding and releasing the back sheet 12 along the flow of the back sheet 12, so that the belt-shaped back surface that moves in one direction by the conveyor 11 is provided. The coating layer 14 made of the dough detergent 13 can be easily formed on the surface of the sheet 12 while intermittently and accurately interposing the non-coating portion 15 in the moving direction X. Production capacity can be improved.

　なお、本発明は上記実施形態に限定されることなく種々の変更が可能である。例えば、シート状部材の表面に敷設層を間欠的に形成した後の工程において、ドウ状洗剤の敷設層を覆って表面側のシート状部材を配設し非敷設部をシールする必要は必ずしもなく、次工程における加工は任意である。さらに、カッテイング手段は必ずしも設ける必要はなく、折り込み手段や折り込み解除手段は上記実施形態のものに限定されるものではない。 Note that the present invention is not limited to the above embodiment, and various changes can be made. For example, in the step after the laying layer is intermittently formed on the surface of the sheet-like member, it is not always necessary to cover the laying layer of the dough-like detergent, dispose the sheet-like member on the surface side, and seal the non-laying portion. Processing in the next step is optional. Further, it is not always necessary to provide the cutting means, and the folding means and the folding releasing means are not limited to those of the above-described embodiment.
