請求項１記載の考案において、サクションポンプを運転すると、中空シリンダ とコーンの間の円筒状中空室内は減圧状態となり、中空シリンダ外周のピンホー ル雌型外周面にまだ穿孔されてない切手印紙類のシート帯が接触していない部分 のすべてのピンホールから外気は吸引されると共に、中空室の一端に設けた外気 取入口より外気を吸入し、円筒状の中空室内には吸出口を向けて相当高速の気流 が流れる。 In the device according to claim 1, when the suction pump is operated, the pressure inside the cylindrical hollow chamber between the hollow cylinder and the cone is reduced, and stamp stamps or the like which have not been punched yet are formed on the outer peripheral surface of the pinhole female die on the outer periphery of the hollow cylinder. Outside air is sucked in from all the pinholes where the seat belt is not in contact, and outside air is taken in through the outside air inlet provided at one end of the hollow chamber, and the suction port is directed toward the cylindrical hollow chamber. A high-speed air stream flows.
【００１２】 この高速気流により、各ピンホール内はベルヌーイの定理により更に減圧状態 が一層起こる。 この状態において、穿孔作業が行われると、各ピンホール内に打ち抜かれた抜 屑はピンホール内にあり、順次雄型たるピンパンチが抜けると、中空室内の減圧 と、この中を流れる気流により各ピンホールは減圧状態となって外気を吸い込み 、各ピンホール内にある前記各抜屑は中空室内に引き込まれ、中空室内を流れる 気流によって吸出孔方向に搬送され、吸出口より排出される。Due to this high-speed airflow, a reduced pressure state is further generated in each pinhole according to Bernoulli's theorem. When the boring operation is performed in this state, the scraps punched in the pinholes are in the pinholes, and when the male pin punches are sequentially removed, the decompression in the hollow chamber and the air flow flowing through them cause The pinhole is in a depressurized state and sucks the outside air, and each of the scraps in each pinhole is drawn into the hollow chamber, is conveyed in the direction of the suction hole by the airflow flowing in the hollow chamber, and is discharged from the suction port.
【００１３】 請求項２記載の考案においては、請求項１の作用の外、コーンの寸法が前述の 範囲としてあるから筒状の中空室内の流速が充分となり、かつ、各ピンホールよ りの吸引作用も、中空室内の減圧効果と気流による各ピンホール内の減圧との相 剰作用により、各抜屑の吸引及び搬送を確実になす。According to the second aspect of the present invention, in addition to the function of the first aspect, since the size of the cone is within the above range, the flow velocity in the cylindrical hollow chamber is sufficient and suction from each pinhole is achieved. With respect to the action, the depressurizing effect in the hollow chamber and the depressurizing action in each pinhole by the air flow are added to each other, so that the suction and transport of each scrap are reliably performed.
【００１４】 請求項３記載の考案においては、コーン先端部においても、シリンダ内周壁及 び吸出口を有する端壁との間に形成された空間の断面積が狭くなっているから、 この部分で、流速が余り減速されず抜屑は救出口内に順次吸引搬送される。According to the third aspect of the present invention, also in the cone tip portion, the cross-sectional area of the space formed between the cylinder inner peripheral wall and the end wall having the suction port is narrow, so that at this portion The flow velocity is not slowed down so much and the scraps are sequentially sucked and conveyed into the rescue exit.
【００１５】 請求項４記載の考案においては、前述の作用の外気取入口が前述の通り設けて あるから、吸出口の面積よりも充分に小さく、吸出口より最も離れた部分の筒状 中空室内においても、外気取入口より吸い込む気流が必ず発生し、抜屑を搬送す るに充分な気流が得られる。In the invention according to claim 4, since the outside air intake of the above-mentioned action is provided as described above, the cylindrical hollow chamber of the portion farthest from the suction port is sufficiently smaller than the area of the suction port. Even in the above case, an airflow that is sucked in from the outside air intake is always generated, and an airflow sufficient to convey the debris is obtained.
【００１６】 請求項５記載の考案においては、前述の作用の外、コーンが鈑金深絞り金属成 形品、若しくは合成樹脂成形品であるから、軽量であり、中空シリンダの運転に は殆ど影響がない。According to the invention of claim 5, in addition to the above-mentioned action, since the cone is a sheet metal deep drawn metal molded product or a synthetic resin molded product, it is lightweight and has almost no effect on the operation of the hollow cylinder.

【００２４】 実施例の作用 実施例１及び実施例２において、サクションポンプを作動させ、被加工物たる 切手・印紙などのシート帯Ｆを図４に示すように前記ロータリー型穿孔装置に通 して運転すると、 また穿孔されてない前記シート帯Ｆが密着している部分においては、すべての ピンホール１９がこのシート帯Ｆによって塞がれ（図４ハッチング部分参照）、 外気の流入は阻止されているが他の領域のすべてのピンホール１９からは外気が 吸い込まれ、特にパンチローラと離反し、各抜屑がピンホール１９中に押し込ま れた部分においては各抜屑は中空室３０中に吸い込まれ、外気取入口２１からの 気流と相俟って各抜屑は吸出口１７方向に流れ、外周筒１１内下側に落下する抜 屑も、この部分のピンホール１９群から吸い込まれる気流によって浮遊しながら 吸出口１７に吸い込まれ、中空シリンダ１０外に排出される。Operation of Embodiment In Embodiment 1 and Embodiment 2, the suction pump is operated, and the sheet band F such as a stamp or a stamp as a workpiece is passed through the rotary punching device as shown in FIG. When the vehicle is operated, all the pinholes 19 are blocked by the seat belt F (see the hatched portion in FIG. 4) in the portion where the seat belt F that is not perforated is in close contact (see the hatched portion in FIG. 4), and the inflow of outside air is blocked. However, the outside air is sucked from all the pinholes 19 in the other regions, and in particular, it is separated from the punch roller, and in the portion where the chips are pushed into the pinholes 19, the chips are sucked into the hollow chamber 30. Together with the air flow from the outside air intake 21, the respective debris flows toward the suction port 17, and the debris that falls to the lower inside of the outer peripheral cylinder 11 is also sucked in from this group of pinholes 19. It is sucked into the suction port 17 while floating by the airflow, and is discharged to the outside the hollow cylinder 10.
【００２５】 実施例１及び２において中空室３０の寸法を前述のように形成したから、この 中の減圧と気流により各ピンホール中の抜屑を確実に中空室３０内に吸い込み、 また中空室３０中を流れる気流が抜屑を搬送するに充分な速度と風量によって前 記抜屑を確実に中空シリンダ外に搬出する。 前述の実施例において中空孔１６の内径を７０ｍｍ、流量を７ｍ3／ｍｉｎと したとき、中空室３０の風速は平均２５乃至３０ｍ／ｓとなる。In the first and second embodiments, since the dimensions of the hollow chamber 30 are formed as described above, the decompression and air flow therein reliably suck the debris in each pinhole into the hollow chamber 30, and The airflow flowing through 30 ensures that the above-mentioned scraps are carried out to the outside of the hollow cylinder at a speed and an air volume sufficient to convey the scraps. In the above embodiment, when the inner diameter of the hollow hole 16 is 70 mm and the flow rate is 7 m 3 / min, the wind velocity in the hollow chamber 30 is 25 to 30 m / s on average.
【００２６】 実施例２の中空室３０は実施例１より狭いため、同一のサクションポンプを用 いたとき、中空室３０中の気圧を更に下げ、気流速度も速く、抜屑搬送能力は実 施例１よりも高い、またコーン２５の先端部３２も半球乃至円錐形状に形成して あるから、この部分で渦流の発生が少なく、風速も減退せず抜屑はスムースに中 空シリンダ１０外に排出される。 前記実施例１においてはコーン２５は鈑金製、実施例２においては合成樹脂製 成形品を例示したが相互に逆の材料でもよいし、その他樹脂の発泡体を用いたも の、木材、又は中空の硬質紙であってもよく、機械的強度さえあれば特に材質に 限定はない。Since the hollow chamber 30 of the second embodiment is narrower than that of the first embodiment, when the same suction pump is used, the atmospheric pressure in the hollow chamber 30 is further lowered, the airflow velocity is high, and the waste carrying capacity is practical. It is higher than 1, and since the tip portion 32 of the cone 25 is also formed in a hemispherical or conical shape, vortex flow is less likely to occur in this portion, the wind speed does not decrease, and the debris is smoothly discharged to the outside of the hollow cylinder 10. To be done. In the first embodiment, the cone 25 is made of sheet metal, and in the second embodiment, a synthetic resin molded product is exemplified. However, the opposite materials may be used, or other resin foam may be used, wood, or hollow. Any hard paper may be used, and the material is not particularly limited as long as it has mechanical strength.

請求項１記載の考案においては、前述の通りの構成及び作用を為すから中空シ リンダ内の体積がコーンによって狭くなり、かつ外周筒内周面に沿った筒状の中 空室となっているから、減圧による吸引作用のみならず、この中空室を流れる気 流速度が中空シリンダ域において充分にあり、ピンホール中の抜屑を一種のベル ヌーイの定理の作用により中空室に吸い込むと共にその気流により抜屑を搬送す る効果を有し、余り出力の大きなサクションポンプを要せず装置全体としての設 置面積も狭くでき、騒音も少なくなる。 According to the first aspect of the invention, since the volume and the inside of the hollow cylinder are narrowed by the cone because of the above-described configuration and operation, the hollow cylinder is a cylindrical hollow space along the inner peripheral surface of the outer peripheral cylinder. Therefore, not only the suction action due to decompression but also the air velocity flowing through this hollow chamber is sufficient in the hollow cylinder region, and the debris in the pinhole is sucked into the hollow chamber by the action of Bernoulli's theorem and This has the effect of conveying debris, does not require a suction pump with a large output, and can reduce the installation area of the entire device and reduce noise.
【００２８】 従って、従来の装置にコーンを取付、外気取入口を設けるだけの改造によって も実施でき、極めて実用性の高いものである。Therefore, it can be implemented by simply modifying the conventional device by attaching a cone and providing an outside air intake port, which is extremely practical.
【００２９】 請求項２記載の考案においては、中空室の形状が円筒状となり、その半径方向 の寸法も狭いため、中空室内での風速を充分に高めることができ、この項に規定 する以下に狭くすることは、加工上も困難を伴い、通風抵抗も増加し、また前記 の中空室の半径方向の寸法を大きくすることは前記風速が充分に得られず抜屑の 搬送能力が低下する。According to the second aspect of the invention, since the hollow chamber has a cylindrical shape and its radial dimension is narrow, the wind velocity in the hollow chamber can be sufficiently increased. Narrowing causes difficulty in processing and increases ventilation resistance, and increasing the size of the hollow chamber in the radial direction reduces the wind speed sufficiently and reduces the scrap transport capability.
【００３０】 請求項３記載の考案においては吸出口近傍の中空シリンダ内においても風速風 量の低下はなく抜屑を搬送する。According to the third aspect of the present invention, the debris is conveyed even in the hollow cylinder near the suction port without a decrease in the wind speed and air volume.
【００３１】 請求項４記載の考案においては、外気取入口の面積の総和を前述の範囲内とし たため、中空室内の減圧効果と充分な流速が得られる。 即ち、外気取入口の総和の面積が、これより大きいときは、中空シリンダ内の 減圧が不充分となり、各ピンホールから抜屑を吸い込む力が減少し、前記外気取 入口の総和の面積がこれより小さいときは中空シリンダ内の風速が不充分となり 、送風抵抗が増大し、風量も不足し、抜屑を搬送する力も低下し、更にフロアー の騒音も大きくなる。According to the fourth aspect of the invention, since the total area of the outside air intake is set within the above range, the depressurizing effect in the hollow chamber and a sufficient flow velocity can be obtained. That is, when the total area of the outside air intake is larger than this, the pressure reduction inside the hollow cylinder becomes insufficient, the force of sucking the debris from each pinhole decreases, and the total area of the outside air intake becomes smaller. If it is smaller, the air velocity in the hollow cylinder will be insufficient, the air flow resistance will increase, the air volume will be insufficient, the force for conveying the debris will also decrease, and the noise on the floor will also increase.
【００３２】 請求項５においては軽量であり、中空シリンダが殆ど重くならず、軸受部の強 度、駆動動力も従来のままのものが使用できる。[0032] In the fifth aspect, it is lightweight, the hollow cylinder hardly becomes heavy, and the strength of the bearing portion and the driving power can be the same as before.
