Description

本発明は、主として板紙などから包装用箱のブランクを打抜き形成する工程で、折曲げ部を形成するために使用される罫線形成テープの端部を傾斜面に削る操作が簡単に行えるようにする罫線形成テープの端削成装置に関するものである。 The present invention is a process of punching and forming a blank for a packaging box mainly from paperboard or the like, and makes it possible to easily perform an operation of cutting an end portion of a ruled line forming tape used for forming a bent portion into an inclined surface. those about the end KezuNaru apparatus ruled line forming tape.

従来、板紙製の包装箱は、所要形状に打抜き型を用いて打抜かれて製造されている。その包装箱のブランクを打抜き作成する工程では、所要の形状に切り抜くと同時に折曲げ部もしくは切込み部を形成するために使用される打抜き型には、例えば図５（ａ）にて示されるように、上型１０１に切断刃１０３と折目を形成するための罫線押し刃１０４とが取付けられている。また、下型１０２には前記罫線押し刃１０４に対応する位置に、折目線を圧刻するための罫線形成テープ１１０が貼着されている。   Conventionally, a packaging box made of paperboard is manufactured by punching into a required shape using a punching die. In the process of punching and creating a blank of the packaging box, a punching die used for forming a bent part or a cut part at the same time as cutting into a required shape is shown in FIG. 5 (a), for example. A cutting blade 103 and a ruled line pressing blade 104 for forming a crease are attached to the upper mold 101. Further, a ruled line forming tape 110 for stamping a crease line is attached to the lower mold 102 at a position corresponding to the ruled line pressing blade 104.

この罫線形成テープ１１０は、所定の間隔を保って相対向して配される二本の溝形成部材１１２，１１２によって罫押し溝１１１が作り出されるようにされている。そして、その罫押し溝１１１は簡単に形成できるように、図６で例示されるように、溝形成部材１１２，１１２の裏面側に剥離紙で被覆される感圧接着剤層１１４を設けられ、その剥離紙を介して形成される前記罫押し溝１１１上に、それら溝形成部材１１２，１１２に掛かるフランジ縁辺１１５ａを両側に有して、罫押し溝１１１の中心線上に合致する罫押し刃のセット溝１１６を備えた取付補助条片１１５を、接合テープ１１７によって剥離可能に取付けて構成されている。   The ruled line forming tape 110 is configured such that a ruled pressing groove 111 is created by two groove forming members 112 and 112 arranged to face each other with a predetermined interval. Then, the ruled groove 111 is provided with a pressure-sensitive adhesive layer 114 covered with release paper on the back side of the groove forming members 112 and 112, as illustrated in FIG. On the ruled groove 111 formed through the release paper, a flange edge 115a that hangs on the groove forming members 112, 112 is provided on both sides, and a ruled blade that matches the center line of the ruled groove 111 is formed. An auxiliary mounting strip 115 having a set groove 116 is attached by a bonding tape 117 so as to be peeled off.

このように構成される罫線形成テープ１１０は、図５（ａ）に装着時の態様を示されるように、打抜き型の上型１０１にセットされた罫線押し刃１０４を前記セット溝１１６に嵌め合わせて（二点鎖線で表わす）上型１０１に仮セットし、裏面側の剥離紙１１３を剥がして感圧接着剤層１１４を露出させた状態で下型１０２の板面上に押付けるようにして、その下型１０２の板面に感圧接着剤層１１４によって罫線形成テープ１１０を貼着させるようにされる。こうすることで、シート材（例えば板紙）を打抜くときに、罫線押し刃１０４が罫線形成テープ１１０の罫押し溝１１１に中心線を合致させて罫線押し（折目線付け）が正確に行えるようにされる。下型１０２の板面に罫線形成テープ１１０が定着されると、取付補助条片１１５を接合テープ１１７とともに取外すことで前記取付補助条片１１５の跡が折目線を付けるための罫線押し溝となり、図５（ｂ）に示されるように、板紙Ｐを打抜く際に罫押しが行えるようになる。   The ruled line forming tape 110 configured as described above is configured such that the ruled line pressing blade 104 set on the upper die 101 of the punching die is fitted into the set groove 116 as shown in FIG. Is temporarily set on the upper die 101 (represented by a two-dot chain line), peeled off the release paper 113 on the back side, and pressed onto the plate surface of the lower die 102 with the pressure-sensitive adhesive layer 114 exposed. The ruled line forming tape 110 is adhered to the plate surface of the lower mold 102 by the pressure sensitive adhesive layer 114. In this way, when punching a sheet material (for example, paperboard), the ruled line pressing blade 104 can make the ruled line push (crease line) accurately by matching the center line with the ruled groove 111 of the ruled line forming tape 110. To be. When the ruled line forming tape 110 is fixed on the plate surface of the lower mold 102, the mounting auxiliary strip 115 is removed together with the joining tape 117, whereby the trace of the mounting auxiliary strip 115 becomes a ruled line pushing groove for making a crease line, As shown in FIG. 5 (b), it becomes possible to perform ruled pressing when the paper board P is punched out.

このような罫線形成テープ１１０は、打抜き型の下型１０２の板面に貼着するに際して、包装箱のブランク形状Ｐａに応じて折目となる罫線ａの形成箇所が交差する場合が多くある（図７（ｂ）参照）。そのために、罫線形成テープ１１０をその軸線に直交する方向に切断して使用すると、罫線押し溝形成部分が分断されるとともに、交差箇所では隣接するもの同士が突き合って正しく板面に接着できないことになる。したがって、罫線形成テープ１１０の端部１１０ａは、図７（ａ）で示されるように、必ず罫線押し溝中心線Ａを基準にして溝形成部材１１２の上縁面１１８を斜めに切断し、尖った状態となるように形成して使用されている。図７（ｂ）において、図中符号ｃは切断線で、符号ｄは逆折り曲げのための破断線である。   When such a ruled line forming tape 110 is attached to the plate surface of the lower die 102 of the punching die, there are many cases where the formation points of the ruled lines a that become creases intersect according to the blank shape Pa of the packaging box ( (Refer FIG.7 (b)). Therefore, if the ruled line forming tape 110 is cut and used in a direction perpendicular to the axis, the ruled line pressing groove forming part is divided, and adjacent ones at the intersecting points collide with each other and cannot be correctly bonded to the plate surface. become. Therefore, as shown in FIG. 7A, the end 110a of the ruled line forming tape 110 is always cut obliquely on the upper edge surface 118 of the groove forming member 112 with the ruled line pushing groove center line A as a reference. It is formed and used so that it will be in the state. In FIG. 7B, the symbol c in the figure is a cutting line, and the symbol d is a breaking line for reverse folding.

ところで、前記罫線形成テープ１１０の端部において、罫線押し溝中心線Ａを基準にして両側を斜め後退方向に切断したものを、そのまま使用すると、その切断面の部分が上下方向に角張るので、罫線押しされたブランクの表面に押し込まれて傷が付くことになり、特に表層が薄い紙質のシート材（例えば化粧シートなど）の場合、製品表面に傷による破断が発生して不具合になる。そこで、従来は罫線押し刃によって罫線形成テープ１１０を板面にセットした後に、前記端部の切断部縁（上縁）を斜めに削って角が立たないように後加工を行っている。   By the way, at the end of the ruled line forming tape 110, if both sides are cut obliquely with respect to the ruled line pushing groove center line A, if used as it is, the portion of the cut surface is angular in the vertical direction. The surface of the blank pressed by the ruled line is pushed and scratched, and in particular, in the case of a sheet-like sheet material having a thin surface layer (for example, a decorative sheet), the product surface breaks due to the scratch and becomes a problem. Therefore, conventionally, after the ruled line forming tape 110 is set on the plate surface by a ruled line pressing blade, the cut end edge (upper edge) of the end portion is cut obliquely so that no corners are formed.

このような切断部縁を削る面取り加工は、従来、カッタナイフなどを用いて人手によって溝形成部材１１２の傾斜端面を斜めに削っている。その溝形成部材１１２は、一般に硬質ファイバーを使用して形成されており、肉厚も１ｍｍ程度のものであるから、板面に貼着された状態で手作業により傾斜面を斜めに削る加工は厄介で、多くの手間を要する作業になる。しかも、一つの打抜き型には多くの罫線形成テープ１１０が使用され、それらの両端を加工するので作業性が低く多くの労力を要求されて非能率であるという問題点がある。   In the conventional chamfering process for cutting the cut edge, the inclined end surface of the groove forming member 112 is cut diagonally by hand using a cutter knife or the like. The groove forming member 112 is generally formed using a hard fiber and has a thickness of about 1 mm. Therefore, the process of cutting the inclined surface obliquely by hand work in a state of being attached to the plate surface is performed. It's cumbersome and a lot of work. In addition, since many ruled line forming tapes 110 are used for one punching die and both ends thereof are processed, there is a problem that workability is low and a lot of labor is required, which is inefficient.

そこで、このような面取り加工を能率よく行う目的で、前記罫線形成テープ（折目形成体）の端部を機械力で加工できるようにする面取り加工機として、土台（受け台）の上に、折目形成体を固定して切削時位置決めを行う位置決め装置と、折目形成体の長手方向端部の面取り切削加工を行う二台の切削装置とを備え、前記位置決め装置によって二箇所の切削装置に対して加工される折目形成体の向きを変えて位置決めされ、その第１の切削位置にて一方の切削装置が折目形成体のほぼ山形形状に加工された端部の一方側を切削し、第２の切削位置にて他方の切削装置が前記折目形成体の端部における他方側を切削するようにされたものが、特許文献１によって提案されている。   Therefore, for the purpose of efficiently performing such chamfering, as a chamfering machine that can machine the end of the ruled line forming tape (fold forming body) with mechanical force, on the base (cradle), A positioning device that fixes the crease forming body and performs positioning at the time of cutting, and two cutting devices that perform chamfer cutting of the longitudinal end portion of the crease forming body, and the cutting device at two locations by the positioning device. The crease forming body to be machined is positioned by changing the orientation, and at the first cutting position, one cutting device cuts one side of the end portion of the crease forming body that has been processed into an approximately chevron shape. However, Patent Document 1 proposes that the other cutting device cuts the other side of the end portion of the fold forming body at the second cutting position.

特開２００３−１６５１６６号公報JP 2003-165166 A

しかしながら、前記特許文献１によって開示されている技術では、二台の切削装置を用いて折目形成体の端部を片側ずつ個々に切削するもので、被切削物である折目形成体を位置決め装置の固定台に固定してから、その固定台を側方に位置する切削装置の方角に所要角度回動させて固定後、対応する側の切削装置を動かして切削刃により折目形成体の側端部上縁を削る操作を行うものである。そのために、折目形成体の左右両方の側端部上縁を加工するのに固定台の向きを変えて二度の操作で、鋭角に形成された端部の面取り加工をすることになり、簡単なようで手数を要するという問題がある。   However, in the technique disclosed in Patent Document 1, the end portion of the crease forming body is cut individually on each side using two cutting devices, and the fold forming body that is the workpiece is positioned. After fixing to the fixing base of the apparatus, the fixing base is rotated by a required angle in the direction of the cutting apparatus located on the side, and then the corresponding cutting apparatus is moved and the fold forming body is moved by the cutting blade. An operation of cutting the upper edge of the side end is performed. Therefore, to process the upper edges of the left and right side end portions of the crease forming body, the orientation of the fixing base is changed twice, and the end portion formed at an acute angle is chamfered. There is a problem that it seems simple and requires time.

しかも、この先行技術においては、被加工物である折目形成体を支持する固定台において、その折目形成体の配置箇所先端側に、縦軸周りに回転可能なローラにてなるストッパが設けられ、折目形成体の先端をそのローラストッパにあてがった状態で位置決めして、固定後に左右の切削装置に対して固定台を回動させて切削位置に向けるようにされている。ところが、このようなローラストッパによる先端位置決めは、切削に際して被加工物（折目形成体）の向きを変えるとき、鋭角に形成されている被加工物が回動容易なようになっている反面、被加工物の鋭角に形成された先端が中心線上に合致していないと、ずれが生じて正しく位置決めできず、切削のために向きを変えるとき突っ張って円滑に回動させることができないという不都合が生じる。したがって、その都度固定を緩めて回動させることになり作業性が低下する。また、位置をずらせることにより、設定されている寸法に面取りができないという問題もある。さらに、この面取り装置では、被加工物を固定台に保持させて面取りのために切削するとき固定台を所要位置まで回動させる必要があるので、被加工物が長尺である場合取扱難く、不安定になって充分に固定できないので、加工操作が円滑に行えないという問題がある。   In addition, in this prior art, in the fixing base that supports the fold forming body that is the workpiece, a stopper made of a roller that is rotatable around the vertical axis is provided on the distal end side of the fold forming body. The fold forming body is positioned with its tip applied to the roller stopper, and after fixing, the fixing base is rotated with respect to the left and right cutting devices to face the cutting position. However, such positioning of the tip by the roller stopper makes it easy to turn the workpiece formed at an acute angle when the orientation of the workpiece (fold forming body) is changed during cutting. If the tip formed at the acute angle of the work piece does not match the center line, it will not be able to position correctly due to deviation, and it will not be able to rotate smoothly when it is turned for cutting. Arise. Therefore, the fixing is loosened and rotated each time, and workability is lowered. In addition, there is a problem that the set dimension cannot be chamfered by shifting the position. Furthermore, in this chamfering device, it is necessary to rotate the fixing base to a required position when holding the workpiece on the fixing base and cutting for chamfering, so it is difficult to handle when the workpiece is long, Since it becomes unstable and cannot be fixed sufficiently, there is a problem that the machining operation cannot be performed smoothly.

本発明は、このような状況に鑑みてなされたもので、簡単な操作で被加工テープを芯出ししてその向きを一定にして保持することにより、能率よく端縁の面取り加工を施すことができる罫線形成テープの端削成装置を提供することを目的とするものである。 The present invention has been made in view of such a situation, and it is possible to efficiently chamfer the edge by centering the tape to be processed by a simple operation and holding the tape in a constant direction. An object of the present invention is to provide an edge cutting device for a ruled line forming tape.

前記位置決め機構２０は、前記受け板２上に設けられる芯出し手段１０の待機位置（被加工テープのセット位置）と対向する受け台３の一方の側部に、前記受け板２の上面と同一レベルで側方に張り出して設けられた受け座５上にて、図３（ａ）で示されるように、その受け座５上の後方寄り位置で直立して植設された枢支ピン２２で基端部を枢支されて水平回動自在な位置決め部片２１からなる。この位置決め部片２１には先端部に前記受け板２の中心線Ｃに向けて鉤型に形成された位置決め片２３が設けられている。また、前記位置決め部片２１は、前記位置決め片２３の形成部から基端部側までの区間の側面２３ａを被加工テープ１１０のセット時に、その被加工テープ１１０と接触しない形状にされている。そして、前記基端部から先端部までの間には、前記枢支ピン２２位置と所要寸法離れて前記受け板２上に直立植設されるガイドピン２５との係合位置から、側面２３ａ側へ所要区間斜めになってその後は側面２３ａに平行するように形成される細長カム長孔２６が設けられている。なお、前記位置決め部片２１の基端には薄金属板にてなる当て板２８が取付けられて、受け台３の案内部３ａの端３ｂとの当接で、位置決め片２３がセット位置に維持されるようになされている。つまり、前記受け台３の案内部３ａの端３ｂが位置決め部片２１の後退位置でのストッパとなる。   The positioning mechanism 20 is the same as the upper surface of the receiving plate 2 on one side of the receiving table 3 facing the standby position (the set position of the tape to be processed) of the centering means 10 provided on the receiving plate 2. As shown in FIG. 3 (a), the pivot pin 22 is installed upright at a position near the rear on the receiving seat 5 on the receiving seat 5 provided to project laterally at the level. The positioning part piece 21 is pivotally supported at the base end part and can be rotated horizontally. The positioning piece 21 is provided with a positioning piece 23 formed in a bowl shape toward the center line C of the receiving plate 2 at the tip. Further, the positioning part piece 21 is shaped so that the side surface 23a of the section from the formation part of the positioning piece 23 to the base end side does not come into contact with the processing tape 110 when the processing tape 110 is set. Then, between the base end portion and the tip end portion, the side surface 23a side from the engagement position with the guide pin 25 that is uprightly implanted on the receiving plate 2 apart from the position of the pivot pin 22 and a required dimension. An elongated cam slot 26 is formed so as to be inclined to the required section and thereafter to be parallel to the side surface 23a. In addition, a contact plate 28 made of a thin metal plate is attached to the base end of the positioning piece 21, and the positioning piece 23 is maintained at the set position by contact with the end 3 b of the guide portion 3 a of the cradle 3. It is made to be done. That is, the end 3 b of the guide portion 3 a of the cradle 3 serves as a stopper at the retracted position of the positioning piece 21.

前記回転カッタ３０は、その刃形成面３１を、被加工テープ１１０（罫線形成テープ）の予めカットされて矢先状に形成された端部の端縁上面を傾斜面に面取り形成できる傾斜角（３３°〜４５°、ただしこれに限定されない）で笠形に形成されている。この回転カッタ３０は、前記受け台３の外側面に取付けられる軸受３２，３２′にて回転自在に支持される回転支持軸３３に固着され、一対刃形成面３１を相対向して対称に配した構造になっている。そして、前記受け板２側に対向する位置で回転軸心を受け板２上にセットされる被加工テープ１１０に直交する状態で、かつその被加工テープ１１０の前記端縁上面を面取りできるように位置させて配置されている。このようにされる回転カッタ３０の回転支持軸３３は、受け台３の一方の側部における軸受３２から突き出されて軸端にプリー３４が取付けられ、受け台３に付設されて図示されない支持部に配置のモータからベルト３５にて駆動されるようになされている（本発明の駆動手段に対応）。ただし、前記駆動手段についてはベルト伝導に限定されず、歯車伝達あるいは減速機付き電動機による直接駆動であってもよい。   The rotary cutter 30 has an angle of inclination (33) in which the blade forming surface 31 can be chamfered to the inclined upper surface of the end edge of the processed tape 110 (ruled line forming tape) that has been cut in advance and formed into an arrow tip shape. It is formed in the shape of a shade at (° to 45 °, but not limited thereto). The rotary cutter 30 is fixed to a rotary support shaft 33 that is rotatably supported by bearings 32 and 32 ′ attached to the outer surface of the cradle 3, and the pair of blade forming surfaces 31 are arranged symmetrically facing each other. It has a structure. And, in a state orthogonal to the processing tape 110 set on the receiving plate 2 at a position facing the receiving plate 2 side, the upper surface of the edge of the processing tape 110 can be chamfered. It is arranged and positioned. The rotation support shaft 33 of the rotary cutter 30 thus configured protrudes from the bearing 32 on one side of the cradle 3 and has a pulley 34 attached to the shaft end. Are driven by a belt 35 (corresponding to the driving means of the present invention). However, the drive means is not limited to belt conduction, and may be gear drive or direct drive by a motor with a speed reducer.

また、前記受け台３には、受け板２が被加工テープの尖端縁を回転カッタ３０によって切削加工するときに支持ローラ３ｂと案内部３ａ，３ａにより案内支持されて進退する際に最前進位置を規定するためのストッパ３６が、前記回転カッタ３０の位置の少し手前に付設されている。このストッパ３６では、位置調節できるストッパピン３６′を設けるようにするのがよい。なお、このストッパ３６は、受け板２が前進したときに芯出し手段の支持部材１１の側面が接触して停止する位置に設けられている。ストッパについては、これに限定されず、受け板の前端と接触して停止するようにしてもよい。図中符号３７は緩み止めナットである。   In addition, when the receiving plate 2 is guided and supported by the supporting roller 3b and the guide portions 3a and 3a when the receiving plate 2 cuts the pointed edge of the tape to be processed by the rotary cutter 30, the most advanced position is reached. A stopper 36 for prescribing is provided just before the position of the rotary cutter 30. This stopper 36 is preferably provided with a stopper pin 36 'whose position can be adjusted. The stopper 36 is provided at a position where the side surface of the support member 11 of the centering means comes into contact and stops when the receiving plate 2 moves forward. The stopper is not limited to this, and may be stopped in contact with the front end of the backing plate. Reference numeral 37 in the figure denotes a locking nut.

このように構成される本実施形態の罫線形成テープの端削成装置１では、被加工テープ１１０（罫線形成テープ）の端部を加工するに際し、位置決め保持させるのに次のような操作により行われる。   In the end cutting device 1 of the ruled line forming tape of the present embodiment configured as described above, when the end of the tape to be processed 110 (ruled line forming tape) is processed, the following operation is performed for positioning and holding. Is called.

まず、被加工テープ１１０を受け板２上に載置する際には、芯出し手段１０の操作レバー１６を引き上げて芯出し部片１４が追従してその下端を引き上げ、受け板２の上面に被加工テープ１１０が受入れられる状態にする。受け板２は、受け台３の案内部３ａの端３ｂに位置決め機構２０の位置決め部片２１基端縁を当接させた状態にして、待機位置に静止させておく。   First, when the workpiece tape 110 is placed on the receiving plate 2, the operation lever 16 of the centering means 10 is pulled up, the centering piece 14 follows, and the lower end is pulled up, and the upper surface of the receiving plate 2 is raised. A state in which the tape to be processed 110 is received is set. The receiving plate 2 is kept stationary at the standby position with the positioning portion piece 21 base end edge of the positioning mechanism 20 in contact with the end 3 b of the guide portion 3 a of the receiving base 3.

この状態で前記位置決め機構２０の位置決め部片２１は、その先端に形成される位置決め片２３が受け板２上面の中央線Ｃ位置に先端を突き出して待機状態にされている。したがって、その位置決め片２３に被加工テープ１１０の尖端を当接させて中心線Ｃ上に沿って載置させる。次いで操作レバー１６を下向きに押下げる。すると、操作レバー１６と一体の操作片１５が支持ピン１９周りに回動されて、カム機能によって支持部材１１に支持されている保持部材１２がコイルバネ１７の押上げ力に打ち勝って下降すると、保持部材１２とともに芯出し部片１４が下降して、その下端部が受け板２上にある被加工テープ１１０の取付補助条片１１１のセット溝１１６に上側から係合する。こうして、芯出し部片１４によって被加工テープ１１０が中心線Ｃに沿って適正な位置に芯出しされる。そして、被加工テープ１１０は、この芯出しと同時に芯出し部片１４の下端に設けられている係止突起１４ａによって係止され、受け板２上に押付けられて固定保持される。   In this state, the positioning part piece 21 of the positioning mechanism 20 is in a standby state in which the positioning piece 23 formed at the tip protrudes the tip to the center line C position on the upper surface of the receiving plate 2. Therefore, the tip of the tape 110 to be processed is brought into contact with the positioning piece 23 and placed along the center line C. Next, the operation lever 16 is pushed downward. Then, the operation piece 15 integrated with the operation lever 16 is rotated around the support pin 19, and when the holding member 12 supported by the support member 11 is lowered by overcoming the push-up force of the coil spring 17 by the cam function, the operation piece 15 is held. The centering piece 14 is lowered together with the member 12, and the lower end thereof engages with the set groove 116 of the attachment auxiliary strip 111 of the work tape 110 on the receiving plate 2 from above. In this way, the processing tape 110 is centered at an appropriate position along the center line C by the centering piece 14. The tape 110 to be processed is locked by a locking projection 14a provided at the lower end of the centering piece 14 at the same time as the centering, and is pressed onto the receiving plate 2 and fixedly held.

こうして、被加工テープ１１０が受け板２上に芯出しされて固定されると、そのままの状態で、予めモータを起動してベルト３５による動力伝達で回転駆動されている回転カッタ３０に向かって受け板２をスライド前進させる。すると、受け板２は受け台３に摺動自在に支持されて、かつ両側を案内部３ａ，３ａによって横振れしない状態で移動できるので直進し、受け板２の尖端が回転する回転カッタ３０の下側に到達するとほぼ同時に被加工テープ１１０の尖端縁部が切削される。受け板２が最前進するとストッパ３６に当接して前進が停止され、この時点で被加工テープ１１０の端縁の上面が傾斜面に仕上げられるのである。被加工テープ１１０には、その裏面側に感圧接着層と樹脂フィルムの層を備えているので、切削時に切削刃による切削抵抗が大きくとも、芯出し固定している芯出し部片１４の下端に多数の係止突起１４ａが後退方向に設けられているので、その係止力の働きでカッタにより引き込まれることなく確実に切削されて、正常に端縁を斜面に仕上げられるのである。   Thus, when the tape 110 to be processed is centered and fixed on the backing plate 2, the motor is started in advance and is received toward the rotary cutter 30 which is driven to rotate by power transmission by the belt 35. Slide the plate 2 forward. Then, since the receiving plate 2 is slidably supported by the receiving table 3 and can be moved on both sides by the guide portions 3a and 3a without being laterally shaken, the receiving plate 2 moves straight, and the tip of the receiving plate 2 rotates. When reaching the lower side, the sharp edge of the tape 110 is cut almost simultaneously. When the backing plate 2 moves forward most, it abuts against the stopper 36 and stops moving. At this point, the upper surface of the edge of the tape 110 to be processed is finished to be an inclined surface. Since the work tape 110 is provided with a pressure-sensitive adhesive layer and a resin film layer on the back side thereof, the lower end of the centering piece 14 that is centered and fixed even if the cutting resistance by the cutting blade is large during cutting. Since a large number of the locking projections 14a are provided in the retreat direction, the locking force can be used to reliably cut the workpiece without being pulled by the cutter, and to finish the edge normally into a slope.

また、被加工テープ１１０が芯出しされて受け板２上にセットされた状態で、切削加工されるために前進させる際、位置決め機構２０の位置決め部片２１は、カム長孔２６に係合するガイドピン２５によって操作される。すなわち、ガイドピン２５は受け板２上に設けられ、位置決め部片２１が受け台３側の受け座５上に配置されて基部を枢支ピン２２に支持されているので、受け板２とともにガイドピン２５が直進すると、係合するカム長孔２６がガイドピン２５の直進に応じて操作され、始めは枢支ピン２２を基点にしてカム長孔２６の傾斜部分をガイドピン２５が移動する間、位置決め部片２１を大きく受け座５側（中心線Ｃから外側に離れる方向）に回動させる。したがって、位置決め部片２１の先端部に位置する位置決め片２３は、受け板２の移動開始と同時に中心線Ｃから外側に向けて離れ（退避し）て、被加工テープ１１０の前進を妨げることはない。ガイドピン２５が前記カム長孔２６の直線部分に移行すると、一旦大きく外向きに回動した位置決め部片２１をゆっくりと内向きに回動させて引き戻す働きをする（図３（ａ）に二点鎖線で表わしている）。そして、先端部の位置決め片２３の端が受け板２の後退時には、被加工テープと接触しない位置に保たれる。また、この位置決め部片２１は、受け板２の後退時に、前記前進時と逆に作動して支障を来たすことはない。   Further, when the workpiece tape 110 is centered and set on the receiving plate 2, the positioning piece 21 of the positioning mechanism 20 engages with the cam long hole 26 when the tape is advanced for cutting. It is operated by the guide pin 25. That is, the guide pin 25 is provided on the receiving plate 2, and the positioning piece 21 is disposed on the receiving seat 5 on the receiving table 3 side and the base is supported by the pivot pin 22. When the pin 25 advances straight, the cam long hole 26 to be engaged is operated in accordance with the straight advance of the guide pin 25. Initially, while the guide pin 25 moves along the inclined portion of the cam long hole 26 with the pivot pin 22 as a base point. Then, the positioning piece 21 is largely rotated to the receiving seat 5 side (in a direction away from the center line C). Therefore, the positioning piece 23 located at the tip of the positioning piece 21 is separated (withdrawn) from the center line C toward the outside simultaneously with the start of the movement of the receiving plate 2 to prevent the tape to be processed 110 from moving forward. Absent. When the guide pin 25 moves to the straight portion of the cam long hole 26, the positioning part piece 21 which has been largely turned outward once is slowly turned inward and pulled back (see FIG. 3 (a)). It is represented by a dotted line). Then, when the end of the positioning piece 23 at the front end is retracted, the position of the positioning piece 23 is kept at a position not in contact with the workpiece tape. Further, the positioning piece 21 does not interfere with the reverse movement of the backing plate 2 when it moves backward.

被加工テープ１１０の切削が終れば、受け板２をそのまま後退させて受け台３の案内部３ａ端３ｂに位置決め部片２１が接して停止する位置まで移動した後、操作レバー１６を上方へ移動させれば、その操作レバー１６と一体の操作片１５もともに支持ピン１９周りに回動し、操作片１５の周面に形成されるカムによって距離ｈ２からｈ１までの差分、保持部材１２が持上げられる。その結果、保持部材１２に付設の芯出し部片１４が上昇して被加工テープ１１０のセット溝から離れ、加工済みのテープを取外すことができる。なお、図４で示されるのは、操作片１５が中間位置にある状態である。 When the cutting of the workpiece tape 110 is finished, the receiving plate 2 is moved back as it is and moved to a position where the positioning piece 21 comes into contact with the guide 3a end 3b of the receiving base 3 and stops, and then the operation lever 16 is moved upward. Then, the operation piece 15 integrated with the operation lever 16 also rotates around the support pin 19, and the difference from the distance h 2 to h 1 by the cam formed on the peripheral surface of the operation piece 15, the holding member 12. Is lifted. As a result, the centering part piece 14 attached to the holding member 12 is lifted away from the set groove of the tape to be processed 110, and the processed tape can be removed. FIG. 4 shows a state in which the operation piece 15 is at an intermediate position.

このように、本実施形態によれば、回転カッタ３０を所定位置で回転駆動させて、これに対して水平移動自在な受け板２上に被加工テープ１１０を芯出し手段１０によって簡単に位置決めと芯出しがとともに行えて、テープの切削部に近い位置で固定保持させて、カッタで尖った端部の両縁の上面を斜面に切削形成することができ、薄い材料で形成されている形成形成テープの端部を無理なく確実に面取り加工ができて、従来手数を要していたこの種加工作業の能率向上を図ることができるのである。   Thus, according to the present embodiment, the rotary cutter 30 is driven to rotate at a predetermined position, and the workpiece tape 110 is easily positioned by the centering means 10 on the receiving plate 2 that can move horizontally relative thereto. It can be centered and fixed and held at a position close to the cutting part of the tape, and the upper surface of both edges of the sharp edge can be cut and formed on the slope, forming a thin material The end of the tape can be chamfered reliably and without difficulty, and the efficiency of this type of machining operation, which has been conventionally required, can be improved.

上述の実施形態では、被加工テープの受け板上での先端位置決め機構について、水平回動式の位置決め部片を用いたものについて記載しているが、これに代えて、図示省略するが、前記受け座位置に中心線Ｃに対して直交する向きで位置決め片を出し入れする形式のものを用いることができる。また、芯出し手段については、前記受け板上に直立固定されて上下動する芯出し部片の支持構造に代えて、図示省略するが受け台の側方から受け板上に回動できる支持体に芯出し部片を支持して、その芯出し部片が被加工テープのセット溝に係合する時点で保持部に係止して固定させ、固定解除時にはその係止部を手で押して開放させ、側方に反転開放できるような構造のものを採用することができる。 In the above-described embodiment, the tip positioning mechanism on the receiving plate of the tape to be processed is described using a horizontal rotation type positioning part piece. A type in which the positioning piece is taken in and out at a position perpendicular to the center line C at the receiving position can be used. Also, the centering means, in place of the supporting structure of the centering piece which moves up and down is upright fixed to the receiving plate, a support which can be rotated in the receiving board from the side of the cradle although not shown The centering part piece is supported by the holder, and when the centering part piece engages with the set groove of the tape to be processed, it is locked and fixed to the holding part. It is possible to adopt a structure that can be reversed and opened sideways.
