Description

本考案は、壁紙糊付機で壁装材に糊を塗布する際に使用する壁紙糊付機用スリッターユニットに関するものである。   The present invention relates to a slitter unit for a wallpaper pasting machine used when applying a paste to a wall covering with a wallpaper pasting machine.

壁紙糊付機は、帯状に搬送されるシート状壁装材(以下、「クロス」とも記す)を後方から引き入れられて前方から引き出される間にこのシート状壁装材の裏面へ糊の塗布を行なうものである。この壁紙糊付機の本体部には、フック等で着脱自在に取付けたり、一体化して取付けられた壁装材裁断装置(スリッター)によって、シート状壁装材の側縁部をその搬送方向に沿って裁断し、所望の壁装材幅に調整していた。   The wallpaper gluing machine applies the paste to the back of the sheet-like wall covering while it is drawn from the rear and pulled out from the front. To do. The main body of this wallpaper pasting machine is detachably attached with a hook or the like, or by a wall covering material cutting device (slitter) attached integrally, the side edge of the sheet-like wall covering is moved in the conveying direction. It was cut along and adjusted to the desired wall covering width.

従来の一般的な壁紙糊付機用のスリッターは、シート状壁装材の搬送方向に対して直交方向に沿って平行に設けられた上下シャフトの対向位置に、上下一対の回転刃を構成するオーバーカッター(上刃)とアンダーカッター(下刃)とがそれぞれ軸止されており、この一対のカッターが搬送されるシート状壁装材を上下から挟んで裁断する構成であった。   A conventional slitter for a general wallpaper pasting machine forms a pair of upper and lower rotary blades at positions opposed to upper and lower shafts provided in parallel along a direction orthogonal to the conveying direction of the sheet-like wall covering material. The overcutter (upper blade) and the undercutter (lower blade) are respectively axially fixed, and the sheet-like wall covering material to which the pair of cutters are conveyed is sandwiched and cut from above and below.

ところで、従来の壁装材施工法としては、重ね合わせ施工法、及び、突き合わせ施工法の2つの工法が代表的である。重ね合わせ施工法は、重ね切り施工法とも呼ばれ、隣り合う壁装材のジョイント部を数cm重ねた後に、両壁装材をカッター等の刃物で重ね裁断し、両壁装材の不要な部分を取り除いた後、ジョイントローラー等で納める施工法である。   By the way, as a conventional wall covering material construction method, two construction methods, a superposition construction method and a butt construction method, are typical. The overlap construction method is also called the overlap cut construction method. After overlapping the joint parts of adjacent wall coverings several centimeters, both wall coverings are overlapped with a blade such as a cutter to eliminate the need for both wall coverings. After removing the part, it is a construction method that fits with a joint roller.

一方、突き合わせ施工法は、突きつけ施工法とも呼ばれ、予め壁面に貼着した壁装材に別の壁装材を貼着する際に、隣接する壁装材同士の小口面を突き合わせて納める施工法である。   On the other hand, the butt construction method is also called a butt construction method. When another wall covering material is pasted on a wall covering material previously pasted on a wall surface, the facet between adjacent wall covering materials is brought into contact with each other. Is the law.

しかしながら、重ね合わせ施工法では、ジョイント部が比較的美しく仕上がるが、下地を直接切るために、下地表面が乾燥に伴う壁装材の縮みに追従できず、目透きや剥離クレームが発生することがあった。特に、下地材には石膏ボード等のように、糊付された壁装材を良好に貼着保持するため表面に紙材が貼着されている場合には、貼着後の壁装材の縮みによって下地材の紙材が両壁装材に引っ張られ、傷が入った部分が目透きとなって現れることがあった。   However, in the overlay construction method, the joint part is finished relatively beautifully, but since the base is cut directly, the base surface cannot follow the shrinkage of the wall covering due to drying, and see-through and peeling complaints may occur. there were. In particular, when the paper material is stuck on the surface in order to hold the glued wall covering material well, such as gypsum board, the surface of the wall covering material after sticking The paper material of the base material was pulled by both wall coverings due to the shrinkage, and the scratched portion sometimes appeared as a see-through.

そこで、現状では、突き合わせ施工法が、内装施工法の主流となりつつあるが、貼着される壁装材の小口部に高い直線性及び平滑性が要求されることとなり、裁断小口部に高い直線性及び平滑性を得ることができる壁装材糊付用スリッターとして、1枚の回転刃によって壁装材を裁断することが提案され(例えば、特許文献1参照)、更に、回転刃の刃部周囲を囲む防護壁に開口部を形成させて、回転刃の切り屑がハウジング内に溜まることなく良好な裁断が維持できる壁紙裁断装置および裁断装置用回転刃内蔵カートリッジ等の工夫も提案されている(例えば、特許文献2参照)。   Therefore, at present, the butt construction method is becoming the mainstream of the interior construction method, but high linearity and smoothness are required for the small edge portion of the wall covering material to be stuck, and a high straight line for the cut small edge portion. It is proposed that the wall covering material is slitted with a single rotating blade as a slitting machine for glueing a wall covering material that can obtain the smoothness and smoothness (see, for example, Patent Document 1), and further, the blade portion of the rotating blade There have also been proposed devices such as a wall paper cutting device and a cartridge with a built-in rotary blade for a cutting device, in which an opening is formed in a protective wall surrounding the periphery, so that good cutting can be maintained without chips of the rotary blade collecting in the housing. (For example, refer to Patent Document 2).

しかしながら、開口部を落下しない切屑も希にある。この場合、回転刃内蔵カートリッジ自体をスリッターから取り外し、回転刃の刃部の周囲を囲む防護壁を分解して落下しない切屑を取り出さざるを得ない課題があった。   However, there are rare chips that do not fall through the opening. In this case, there is a problem that the cartridge built in the rotary blade itself is removed from the slitter, and the protective wall surrounding the blade portion of the rotary blade must be disassembled to take out chips that do not fall.

本考案は、回転刃の刃部周囲を囲む防護壁内に切屑等が発生してカートリッジ内部から留まって出ない場合に迅速に取り出すことが可能な壁紙糊付機用スリッターユニットを得ることを目的とする。また、切屑等を取り出す際に不用意に回転刃が駆動しない安全機構手段を備えた壁紙糊付機用スリッターユニットを得ることを目的とする。   It is an object of the present invention to obtain a slitter unit for a wallpaper pasting machine that can be quickly removed when chips or the like are generated in the protective wall surrounding the periphery of the rotary blade and do not stay inside the cartridge. And It is another object of the present invention to obtain a slitter unit for a wallpaper pasting machine provided with a safety mechanism means in which a rotary blade is not driven carelessly when taking out chips and the like.

Thereby, when taking out chips etc., a rotary blade does not drive carelessly. The safety mechanism includes, for example, a reed switch that forms a power supply circuit to the rotation driving means by the magnetic force of a magnet mounted on the door when the door of the guide member is closed. As a result, it is possible to provide a safety mechanism with the same shape and size as the conventional slitter unit, and it is possible to replace it with a conventional slitter unit already on the market.

図1は壁紙糊付機用スリッターを備えた壁紙糊付機の簡略構成を示す説明図である。図1に示す通り、自動壁紙糊付機本体部1には、主なロールとして上部構体2内に糊付機本体部1内に後部側から取り込まれたクロス(壁装材)4に糊付機本体部1の前部方向への送り出し張力を付与するための押さえロール11と、クロス4を上から押さえて追従回転するドライブロール12とが互いに所定間隔で平行に配列されるように、それぞれ上部構体2の側板に軸支されている。   FIG. 1 is an explanatory diagram showing a simplified configuration of a wallpaper pasting machine equipped with a slitter for wallpaper pasting machine. As shown in FIG. 1, the automatic wallpaper pasting machine main unit 1 is glued to a cloth (wall covering) 4 taken from the rear side into the pasting machine main unit 1 in the upper structure 2 as a main roll. The press roll 11 for applying the feed tension in the front direction of the machine main body 1 and the drive roll 12 that follows and rotates by pressing the cross 4 are arranged in parallel at predetermined intervals, respectively. It is pivotally supported on the side plate of the upper structure 2.

また、下部構体3内には、糊桶5内に収容されている糊を糊上げロール16で糊上げし、これに当接して糊を転写し搬送されてくるクロス4の裏面に塗布する糊付ロール6と、糊付けロール6に接して糊量を調節するドクターロール7と、前記ドライブロール12と共にクロス4に適度な張力を与えて前部方向へ送り出す均しロール8とが、互いに所定間隔を持って平行に配列されるように、下部構体3の側板に軸支されている。   Further, in the lower structure 3, the glue contained in the glue basket 5 is glued by a glue raising roll 16, and glue is applied to the back surface of the cloth 4 transferred in contact with the glue. An attaching roll 6, a doctor roll 7 that adjusts the amount of glue in contact with the gluing roll 6, and a leveling roll 8 that applies an appropriate tension to the cloth 4 together with the drive roll 12 and feeds it in the front direction are mutually spaced apart from each other by a predetermined distance. Are pivotally supported on the side plate of the lower structure 3 so as to be arranged in parallel.

また、クロス4は上部構体2の上部ピンチロール13と、下部構体3の下部ピンチロール15との引き込み力で糊付機本体1の背面側のスリッター20を通って糊付機本体に引き込まれる。本実施例のスリッター20は、図示しない駆動源をスリッター20に内蔵しているものを示しているが、糊付機本体から得てもよい。   The cross 4 is drawn into the gluing machine main body through the slitter 20 on the back side of the gluing machine main body 1 by the pulling force of the upper pinch roll 13 of the upper structural body 2 and the lower pinch roll 15 of the lower structural body 3. Although the slitter 20 of the present embodiment shows a drive source (not shown) built in the slitter 20, it may be obtained from the gluing machine main body.

クロスの糊付施工は、糊付機脚部9から後方へ伸びているクロス受けブラケット10の先端部に軸支されているクロス原反14からクロス4先端を引き出し、スリッター20の背面側から、寸動回動させてスリッター20内部へ引き込みつつ、回転刃によって両耳部(側縁部)を裁断しながら、スリッター20前方から引き出す。尚、両耳部は耳切ガイドから排出される。   For the pasting of the cloth, the tip of the cloth 4 is pulled out from the original cloth 14 pivotally supported by the tip of the cross receiving bracket 10 extending backward from the leg 9 of the pasting machine, and from the back side of the slitter 20, The slitter 20 is pulled out from the front of the slitter 20 while being turned and moved into the slitter 20 while cutting both ears (side edges) with a rotary blade. Both ears are discharged from the ear-cut guide.

スリッター20の前方から引出された裁断されたクロス4の先端を、上部構体2を開けた状態で糊付機本体部1の前方から垂らすように下部構体3上に載置した後、上部構体2を閉めて所定ロール間に挟み込んだ初期設定状態を得る。   After the tip of the cut cloth 4 drawn out from the front of the slitter 20 is placed on the lower structure 3 so as to hang from the front of the gluing machine main body 1 with the upper structure 2 opened, the upper structure 2 Is closed to obtain an initial setting state sandwiched between predetermined rolls.

初期設定終了後、糊付機の駆動源モーターの駆動を開始すると共に、スリッター20のモーターの駆動を開始する。これによって、クロス4のスリッター20内の通過の際に回転刃の回転によって両耳部の裁断と、該裁断による幅調整後のクロス4の糊付機本体部1内での糊付が連続的に行われる。尚、スリッターの駆動源としては、モーターの駆動で行うように構成したが糊付機の駆動源の駆動をギア等で伝達してもよい。   After completion of the initial setting, the driving of the drive source motor of the gluing machine is started and the driving of the motor of the slitter 20 is started. As a result, when the cross 4 passes through the slitter 20, the cutting of both ears by the rotation of the rotary blade and the pasting of the cross 4 in the pasting machine main body 1 after the width adjustment by the cutting are continuously performed. To be done. The slitter drive source is configured to be driven by a motor. However, the drive of the gluing machine drive source may be transmitted by a gear or the like.

図2はスリッターの構成を示す分解図である。図2に示されるように、スリッター20は、断面が略コ字状の本体ハウジング21とこの両側に配された本体側板22とを備える。本体側板22の各々には一対のフック23が取付けられ、これらを糊付機本体1の背面へ引っ掛けることにより設置される。   FIG. 2 is an exploded view showing the configuration of the slitter.

FIG. 4 is a perspective view of the slitter unit. FIG. 5 is a perspective view showing a state in which the door of the guide member is opened. FIG. 6 is an explanatory diagram showing a configuration of a main part of FIG. As shown in FIGS. 3 to 6, the slitter unit 30 includes a cutter box 33 and a motor bracket 34 as a cartridge with a built-in rotary blade.

カッターボックス33は、壁装材当接側以外の回転刃40周囲を側断面略コの字形状に覆う3面の防護壁(33a,33b,33c)と、回転刃40をボスを介して軸支するシャフト42の一端を枢支する側壁板33dとにより外形が略筐体形状に構成されている。カッターボックス33の側壁板33dには固定ブラケット32が配されている。これらカッターボックス33とモーターブラケット34とはスリッター1の裁断面を形成しているハウジング21内に設置される。これら防護壁(33a,33b,33c)には、それぞれ指が入らない程度の幅のスリット状開口部Sが複数個ずつほぼ全壁面に亘って穿設されている。   The cutter box 33 includes three protective walls (33a, 33b, 33c) that cover the periphery of the rotary blade 40 other than the wall material contact side in a substantially U-shaped side section, and the rotary blade 40 via a boss. The outer shape of the shaft 42 is substantially a casing by the side wall plate 33d that pivotally supports one end of the shaft 42 to be supported. A fixing bracket 32 is disposed on the side wall plate 33 d of the cutter box 33. The cutter box 33 and the motor bracket 34 are installed in the housing 21 forming the cut surface of the slitter 1. Each of the protective walls (33a, 33b, 33c) is provided with a plurality of slit-shaped openings S each having a width that does not allow a finger to enter over the entire wall surface.

カッターボックス33は内部に回転刃40が回転可能に軸支され、その前面には裁断後のクロス側端部をスリッタ本体外側へ導出するガイド部材41が取り付けられている。その回転刃40の裁断位置に至る部分には押さえ部材39が装着されており、クロスを回転刃40方向へ押さえる。このカッターボックス33は更に回転刃40のシャフト42にモーターの回転軸が連結されたモーターブラケット34内部の回転刃駆動手段としてのモーター35にギアユニット36及びギアユニットカバー37を介して連結されている。   The cutter box 33 is rotatably supported inside by the rotary blade 40, and a guide member 41 is attached to the front surface of the cutter box 33 to guide the cross-side end after cutting to the outside of the slitter body. A pressing member 39 is attached to the portion of the rotary blade 40 that reaches the cutting position, and presses the cloth in the direction of the rotary blade 40. The cutter box 33 is further connected via a gear unit 36 and a gear unit cover 37 to a motor 35 as a rotary blade driving means inside a motor bracket 34 in which a motor rotation shaft is connected to a shaft 42 of the rotary blade 40. .

スリッターユニット30を吊下げる吊下げ機構としては、前述のオーバステー24にスライド可能に保持されるスライドブラケット38にモーターブラケット34を吊下することによる。更に、スリッターユニット30を固定する固定機構としては、カッターボックス33の側部に設けられた固定ブラケット32に挿通される固定ネジ31を本体ハウジング21のスリット溝25に緊締することによる。   The suspension mechanism for suspending the slitter unit 30 is by suspending the motor bracket 34 on the slide bracket 38 that is slidably held by the overstay 24 described above. Further, as a fixing mechanism for fixing the slitter unit 30, the fixing screw 31 inserted into the fixing bracket 32 provided on the side of the cutter box 33 is tightened into the slit groove 25 of the main body housing 21.

回転刃40のシャフト42は、カッターボックス33の固定ブラケット32側の側壁板33dにベアリング43を介して取付けられる。回転刃40は厚さが0.5mmの片切刃であり、回転刃取付ボス44にネジ45で取付けられる。回転刃40とこれを保持する回転刃取付ボス44とを保持したシャフト42は、ギアユニット36の出力軸36’に平爪部42’で接続されており、バネ46を介して装着されることにより、回転刃40は常に外方向への押圧力が配されている。   The shaft 42 of the rotary blade 40 is attached to the side wall plate 33 d of the cutter box 33 on the fixed bracket 32 side via a bearing 43. The rotary blade 40 is a single-cut blade having a thickness of 0.5 mm, and is attached to the rotary blade mounting boss 44 with a screw 45. A shaft 42 that holds the rotary blade 40 and the rotary blade mounting boss 44 that holds the rotary blade 40 is connected to the output shaft 36 ′ of the gear unit 36 by a flat claw portion 42 ′ and is mounted via a spring 46. Thus, the rotary blade 40 is always provided with an outward pressing force.

一方、カッターボックス33内のクロス裁断位置には、クロスを介した対向面側で回転刃40のシャフト42と略平行に配された取付軸51に回動自在に軸支された回転部材50を備える。   On the other hand, at the cross cutting position in the cutter box 33, the rotating member 50 pivotally supported by the mounting shaft 51 disposed substantially parallel to the shaft 42 of the rotary blade 40 on the opposite surface side through the cross is provided. Prepare.

取付軸51は軸先端部と取付け座金とを各々ガイド部材41にネジで固定されている。この取付軸51のガイド部材41への取付け角度は回転刃40のシャフト42と略平行であるが、後述するように3度以上10度以下、具体的には3度傾けて固定される。また、回転部材50はベアリングを介して回動自在に取付軸51に取付けられている。この回転部材50は円筒状の構造である。また、回転部材50の上面の平坦面部の一部が、裁断地点を端部とした回転刃40の周縁部との部分的な重なり領域を構成するように配置されている。回転部材50の取付軸51にはバネ52が介されており、回転部材50を当接した回転刃40の刃部に付勢・押圧している。   The mounting shaft 51 has a shaft tip portion and a mounting washer fixed to the guide member 41 with screws. The attachment angle of the attachment shaft 51 to the guide member 41 is substantially parallel to the shaft 42 of the rotary blade 40, but is fixed at an angle of 3 degrees or more and 10 degrees or less, specifically, 3 degrees as will be described later. The rotating member 50 is attached to the attachment shaft 51 through a bearing so as to be rotatable. The rotating member 50 has a cylindrical structure. Further, a part of the flat surface portion on the upper surface of the rotating member 50 is arranged so as to constitute a partial overlapping region with the peripheral edge portion of the rotary blade 40 having the cutting point as an end portion. A spring 52 is interposed on the mounting shaft 51 of the rotating member 50 and urges and presses the blade portion of the rotating blade 40 that contacts the rotating member 50.

取付軸51がシャフト42に対して3度以上10度以下、具体的には3度傾けて固定されているため、回転部材50の平坦面部の回転刃40の刃部に対する傾斜角度は3度以上10度以下、具体的には3度となる。これにより、裁断される壁装材の裁断小口部に高い直線性及び平滑性を得ることができることは勿論のこと、厚手の織物壁装材や繊維を不規則に表層に備えた壁装材でも良好な裁断状態を得ることができる。また、取付軸51自体を傾けて固定し、更にベアリングを介して回転部材と取付軸51に軸支しているため、長期に亘って使用しても回転部材50の平坦面部の回転刃40の刃部に対する傾斜角度の変化が極力少なくなるという利点もある。   Since the mounting shaft 51 is fixed to the shaft 42 with an inclination of 3 degrees or more and 10 degrees or less, specifically 3 degrees, the inclination angle of the flat surface portion of the rotating member 50 with respect to the blade portion of the rotary blade 40 is 3 degrees or more. It is 10 degrees or less, specifically 3 degrees. As a result, it is possible to obtain high linearity and smoothness at the cut edge of the wall covering material to be cut, as well as thick woven wall coverings and wall coverings irregularly provided with fibers on the surface layer. A good cutting state can be obtained. Further, since the mounting shaft 51 itself is tilted and fixed, and further supported by the rotating member and the mounting shaft 51 via a bearing, the rotating blade 40 of the flat surface portion of the rotating member 50 can be used over a long period of time. There is also an advantage that the change in the inclination angle with respect to the blade portion is minimized.

尚、回転部材50は回転刃40の径と比較して、1/3となっているため、押圧された回転刃40の回転力によって、独自の駆動源を有さない回転部材50を保持した取付軸51が容易に回動することが可能となる。   In addition, since the rotation member 50 is 1/3 compared with the diameter of the rotary blade 40, the rotary member 50 which does not have an original drive source was hold | maintained with the rotational force of the pressed rotary blade 40. The attachment shaft 51 can be easily rotated.

また、回転部材50は、回転刃40に当接する部分がセラミック製の砥材からなる。このため、使用に伴って回転刃40の刃部を研ぐことになり、回転刃40の長期にわたる使用が可能となる。   Further, the rotating member 50 is made of a ceramic abrasive material at a portion that contacts the rotating blade 40. For this reason, the blade part of the rotary blade 40 is sharpened with use, and the rotary blade 40 can be used over a long period of time.

ガイド部材41には、図4〜図6に示す通り、部材の上縁部に形成された支点部を中心にしてカッターボックス33の内部の回転刃40の周囲を露出させる開閉扉41aを備える。開閉扉41aには磁石41bが埋め込まれており、ガイド部材41本体側には開閉扉41aを綴じた際の磁石41bの対向位置にリードスイッチ41cが埋め込まれている。   As shown in FIGS. 4 to 6, the guide member 41 includes an opening / closing door 41 a that exposes the periphery of the rotary blade 40 inside the cutter box 33 around a fulcrum portion formed on the upper edge portion of the member. A magnet 41b is embedded in the opening / closing door 41a, and a reed switch 41c is embedded on the guide member 41 main body side at a position facing the magnet 41b when the opening / closing door 41a is bound.

このリードスイッチ41cは、ガイド部材41の開閉扉41aが閉鎖された場合に、この開閉扉41aに搭載された磁石41bの磁力によってモーター35への給電回路を形成する。これにより、カッターボックス33内に留まった切屑等を取り出す際に不用意に回転刃40が駆動しない。尚、本考案のスリッターユニット20及びカッターボックス33では、既に市販されている従来のスリッターユニット及びカッターボックスと同等の寸法形状にすることが可能となり、従来のスリッターユニット及びカッターボックスと交換することにより、回転刃の刃部周囲を囲む防護壁内に切屑等が発生してカートリッジ内部から留まって出ない場合に迅速にしかも安全に取り出すことが可能となる。   The reed switch 41c forms a power feeding circuit to the motor 35 by the magnetic force of the magnet 41b mounted on the door 41a when the door 41a of the guide member 41 is closed. Thereby, when taking out the chips etc. which remain | survived in the cutter box 33, the rotary blade 40 is not driven carelessly. In addition, the slitter unit 20 and the cutter box 33 of the present invention can be made to have the same size and shape as the conventional slitter unit and cutter box that are already on the market, and can be replaced with the conventional slitter unit and cutter box. When chips or the like are generated in the protective wall surrounding the periphery of the blade portion of the rotary blade and do not stay out of the cartridge, it can be quickly and safely removed.
