しかしながら、上記のような従来のシ−ト状物パンチング装置では、必要な孔径に応じたパンチング用の筒刃を孔径に応じた数を予め用意しておく必要があると共に、パンチング用の筒刃をその都度付け替える作業が必要となる。
パンチングされるフイルム又はシ−ト状物も、例えば二軸延伸ポリプロピレンフィルム（ＯＰフィルム）、無延伸ポリプロピレンフィルム（ＣＰフィルム）、Ｔ．Ａ．Ｆ共押多層フィルム、ビニロンフィルム（ＶＦフィルム）、トスロンポリビニルアルコ−ルフィルム、紙、及びにれらの多層フィルム等々多岐にわたっている。上記の中、特に粘着性の強いＴ．Ａ．Ｆ共押多層フィルムでは従来のシ−ト状物パンチング装置では、その粘着性のためにパンチングに不良品がでることがしばしば発生した。However, in the conventional sheet punching apparatus as described above, it is necessary to prepare in advance a number of punching cylinder blades corresponding to the required hole diameter according to the hole diameter, and the punching cylinder blade It will be necessary to replace each time.
Films or sheets to be punched are also, for example, biaxially stretched polypropylene films (OP films), unstretched polypropylene films (CP films), T.P. A. F co-pressed multi-layer film, vinylon film (VF film), toslon polyvinyl alcohol film, paper, and multi-layer film of these, etc. Among the above, T. A. In the F co-pressed multilayer film, in the conventional sheet punching apparatus, defective products often occur in punching due to the adhesiveness.

更に、円盤に下向きの刃物を取り付けるものでは、真円状に孔明けすることができるが、例えば楕円形状その他の異形の孔を開けることはできない。Furthermore, when a downward blade is attached to the disk, a perfect circle can be drilled, but an elliptical or other irregular hole cannot be formed, for example.

この考案の目的とするところは、シ−ト状物に孔開け作業をするに際して、非円形、例えば楕円形状、ハ−ト型又は菱形形状の孔明けも極めて容易に実行することができると共に、極めて粘着性の強いＴ．Ａ．Ｆ共押多層フィルムにも正確無比の孔開けを行うことができるシ−ト状物の孔開け装置を提供することである。The object of the present invention is that when drilling a sheet-like material, non-circular, for example, elliptical, heart-shaped or rhombus-shaped drilling can be performed very easily, T. is extremely sticky. A. An object of the present invention is to provide a sheet-like material perforating apparatus capable of accurately and unequivocally perforating an F co-pressed multilayer film.

本考案は上記の目的を達成するために、モ−タ−取付け台上に設置されたモ−タ−と、該モ−タ−の回転により回転する原動プ−リ−と、前記原動プ−リ−と離間した位置に設置される従動プ−リ−と、原動プ−リ−と従動プ−リ−との間に掛けられたオ−プンベルトと、前記オ−プンベルトの外面に下向きに取付けられると共にその刃先を前記オ−プンベルトの下辺より突出させてなる切断刃と、前記モ−タ−取付け台を上下動させる弾力的加圧手段とからなるようにした。In order to achieve the above object, the present invention provides a motor installed on a motor mounting base, a driving pulley rotating by rotation of the motor, and the driving pulley.

以下、この考案の実施の形態を以下に詳細に説明する。
図１〜図６において、上部固定板１は本願考案のシ−ト状物の孔開け装置Ａの側板２によって一定位置に固定する。上部固定板１の上面には上下シリンダ−３が設置されると共に、上下シリンダ−３の上下シリンダ−軸４の下部は上下シリンダ−３の下部中央部に開けられた貫通孔を貫通して上下固定板５に固定してある。更に、上下固定板５の下部離間位置には設置板６が設けられ、設置板６の上面には原動プ−リ−用のモ−タ−７及びこのモ−タ−７の横側に従動プ−リ−用の保持部８が設置されている。上下固定板５と設置板６とは支持扞２０によって支持されている。Hereinafter, embodiments of the present invention will be described in detail below.
1 to 6, the upper fixing plate 1 is fixed at a fixed position by the side plate 2 of the sheet-like object punching device A of the present invention. The upper and lower cylinders 3 are installed on the upper surface of the upper fixing plate 1, and the upper and lower cylinders of the upper and lower cylinders 3 and the lower part of the shaft 4 pass through a through hole formed in the lower central part of the upper and lower cylinders 3 and move up and down. It is fixed to the fixed plate 5. Further, an installation plate 6 is provided at a lower spaced position of the upper and lower fixed plates 5, and a motor 7 for driving pulley and a lateral side of the motor 7 are driven on the upper surface of the installation plate 6. A holding portion 8 for pulley is installed. The upper and lower fixed plates 5 and the installation plate 6 are supported by a support rod 20.

前記原動プ−リ−用のモ−タ−７と、従動プ−リ−用の持部８の下方にはそれぞれ原動プ−リ−９と従動プ−リ−１０とは、前記原動プ−リ−用のモ−タ−７の回転軸１１と従動プ−リ−用の保持部８の回転軸１２とによって回転可能に支持されている。更に、原動プ−リ−９と従動プ−リ−１０との間には上下所定幅を有するプ−リ−ベルト１３がオ−プン状に掛けられると共に、該ベルト１３には細幅カッタ−１４の刃先１５がプ−リ−ベルト１３の下端部より突出するように固定される。設置板６の更に下部離間位置にゴムクッョン板のような弾性部材で形成された弾性板１６が適数個の押しバネのような押圧材１７に弾力的支持されている。弾性板１６には前記細幅カッタ−の移動領域には空隙部１８が形成される。孔開け装置Ａの作業受け台１９及びそのの上面にも作業用ゴムクッョン板２１にも前記細幅カッタ−の移動領域には空隙部２２、２３が形成される。Below the motor pulley 7 for the driving pulley and the holding portion 8 for the driving pulley, the driving pulley 9 and the driven pulley 10 are respectively connected to the driving pulley. The rotating shaft 11 of the motor 7 for the reel and the rotating shaft 12 of the holding portion 8 for the driven pulley are rotatably supported. Further, a pulley belt 13 having a predetermined vertical width is hung between the driving pulley 9 and the driven pulley 10 in an open shape, and the belt 13 has a narrow cutter. The 14 cutting edges 15 are fixed so as to protrude from the lower end of the pulley belt 13. An elastic plate 16 formed of an elastic member such as a rubber cushion plate is elastically supported by an appropriate number of pressing members 17 such as push springs at a further lower spacing position of the installation plate 6. A gap 18 is formed in the elastic plate 16 in the moving region of the narrow cutter. Cavities 22 and 23 are formed in the movement area of the narrow cutter on the work cradle 19 of the drilling device A and the upper surface of the work cradle 19 and the work rubber cushion plate 21.

上記支持扞２０は、上下固定板５と設置板６とを連結固定してあるが、この支持扞２０は、上部固定板１を摺動自在に貫通させてある。The support rod 20 connects and fixes the upper and lower fixing plates 5 and the installation plate 6, and the support rod 20 penetrates the upper fixing plate 1 slidably.

この孔開け装置Ａは、孔開け作業中は、常時的に原動プ−リ−用のモ−タ−７が回転し、従って、原動プ−リ−９と従動プ−リ−１０とプ−リ−ベルト１３及びプ−リ−ベルト１３に固定された細幅カッタ−１４の刃先１５も回転しており、孔開け作業中に、被加工用のシ−ト状物Ｂが作業台１９及びゴムクッション２１等の位置に移送されてくると、それを電気的に感知して上下シリンダ−３の上下シリンダ−軸４が瞬間的に上下固定板５及び設置板６を押し下げると、作業台１９に設けられたゴムクッション２１の上の被加工用のシ−ト状物Ｂを弾性部材で形成された弾性板１６で一時的に挟着保持する。この瞬間に、常時回転している細幅カッタ−１４の刃先１５が被加工用のシ−ト状物Ｂの所定位置を正確に行うようにしてある。なお、上記プ−リ−ベルト１３はタイミンクベルトで正確なベルトの回転が得られるようにしてもよい。In this drilling apparatus A, the motor pulley 7 for the driving pulley is always rotated during the drilling operation, so that the driving pulley 9, the driven pulley 10, and the pulley are rotated. The cutting edge 15 of the narrow cutter 14 fixed to the belt 13 and the pulley belt 13 is also rotating. During the drilling operation, the sheet B to be processed becomes the work table 19 and When it is transferred to the position of the rubber cushion 21 or the like, when it is electrically sensed and the upper and lower cylinders and shafts 4 of the upper and lower cylinders 3 momentarily push down the upper and lower fixing plates 5 and the installation plate 6, the work table 19 A sheet B to be processed on the rubber cushion 21 provided on is temporarily sandwiched and held by an elastic plate 16 formed of an elastic member. At this moment, the cutting edge 15 of the narrow cutter 14 that is always rotating is configured to accurately perform the predetermined position of the sheet B to be processed. The pulley belt 13 may be a timing belt so that accurate belt rotation can be obtained.

作業台に被加工用のシ−ト状物Ｂが送られると、上下シリンダ−３の下動、孔開け位置の割り出し、孔開け作業、及び孔開け作業完了後の上下シリンダ−３の上動の一連の動作は全て電気的に感知して孔開け作業を瞬間的に行うようにしている。２９は穿孔である。When the sheet B to be processed is sent to the work table, the upper and lower cylinders 3 are moved downward, the drilling position is determined, the drilling operation, and the upper and lower cylinders 3 are moved upward after completion of the drilling operation. The series of operations are all electrically sensed and the drilling operation is performed instantaneously. 29 is a perforation.

なお、原動プ−リ−９と従動プ−リ−１０との間は固定的でなく、従動プ−リ−１０の位置を移動して微調整をするために前記保持部８に対して押動し得る螺着調整ネジ２６が保持部８の近接位置に取付板２７に設けたネジ孔２８に螺動するようにしてある。保持部８は、図示を省略した溝孔にそって微動するようにしてあるものである。Note that the driving pulley 9 and the driven pulley 10 are not fixed, and are pushed against the holding portion 8 in order to move the position of the driven pulley 10 and make fine adjustments. A movable screwing adjustment screw 26 is screwed into a screw hole 28 provided in the mounting plate 27 at a position close to the holding portion 8. The holding portion 8 is configured to be finely moved along a groove hole (not shown).

なお、図３〜図４及び図５〜図６のようにプ−リ−ベルトを張架する状態で原動プ−リ−９を回転させた場合には細幅カッタ−１４の刃先１５は略楕円形状となるから必然的に略楕円形状で孔開けが行われる。When the driving pulley 9 is rotated with the pulley belt stretched as shown in FIGS. 3 to 4 and FIGS. 5 to 6, the cutting edge 15 of the narrow cutter 14 is substantially omitted. Since it has an elliptical shape, it is inevitably performed with a substantially elliptical shape.

図７（イ）、（ロ）、（ハ）に示すようにプ−リ−ベルトを張架するように案内回転子２４を随時に設けることにより、図８（イ）、（ロ）、（ハ）のような各種の孔開け作業を可能となるものである。As shown in FIGS. 7 (a), 7 (b) and 7 (c), a guide rotor 24 is provided as needed to stretch the pulley belt, so that FIGS. It is possible to perform various drilling operations as in (c).

プ−リ−ベルト１３は、図３〜図４に示すような帯状のものが一般的であるが、より安価にしたい場合には、図５〜図６に示すような原動ロ−ププ−リ−２５と従動ロ−ププ−リ−３５に複数のロ−プベルト３０、３０を張架することもできる。The pulley belt 13 is generally a belt-like belt as shown in FIGS. 3 to 4. However, if it is desired to make the belt cheaper, the driving rope pulley as shown in FIGS. A plurality of rope belts 30, 30 can be stretched between -25 and driven rope pulley 35.

このような刃物による切断による場合、二軸延伸ポリプロピレンフィルム（ＯＰフィルム）、無延伸ポリプロピレンフィルム（ＣＰフィルム）、Ｔ．Ａ．Ｆ共押多層フィルム、ビニロンフィルム（ＶＦフィルム）、トスロンポリビニルアルコ−ルフィルム、のようなシ−ト状物Ｂは従来のパンチング方式では困難とされた孔開け作業でもであっても、通常のプラスチックの流れ作業の工程の中に組み込んで行えのである。In the case of cutting with such a blade, a biaxially stretched polypropylene film (OP film), an unstretched polypropylene film (CP film), T.I. A. Sheets B such as F co-pressed multilayer film, vinylon film (VF film), and Toslon polyvinyl alcohol film can be used even in a perforating operation that has been difficult with the conventional punching method. It can be done by incorporating it into the plastic flow process.

この考案は、モ−タ−取付け台上に設置されたモ−タ−と、該モ−タ−の回転により回転する原動プ−リ−と、前記原動プ−リ−と離間した位置に設置される従動プ−リ−と、原動プ−リ−と従動プ−リ−との間に掛けられたオ−プンベルトと、前記オ−プンベルトの外面に下向きに取付けられると共にその刃先を前記オ−プンベルトの下辺より突出させてなる切断刃と、前記モ−タ−取付け台を上下動させる弾力的加圧手段とから構成することにより、シ−ト状物Ｂの孔開け作業をシ−ト状物Ｂの移送工程中に行うことができると共に、安価な細幅の切断刃をオ−プンベルトに随時に取り付けることができるため、例えば、プラスチックの手提げ袋の手提げ孔を開けるのに便利である。The present invention provides a motor installed on a motor mounting base, a driving pulley that rotates by the rotation of the motor, and a position separated from the driving pulley. Driven pulley, an open belt hung between the driving pulley and the driven pulley, and attached to the outer surface of the open belt in a downward direction, and the cutting edge thereof is attached to the open belt. By forming the cutting blade projecting from the lower side of the Punbelt and the elastic pressurizing means for moving the motor mounting base up and down, the punching operation of the sheet-like object B is performed in a sheet form. Since it can be performed during the transfer process of the object B, and an inexpensive narrow cutting blade can be attached to the open belt at any time, it is convenient for, for example, opening a handbag hole of a plastic handbag.
