Abstract

PROBLEM TO BE SOLVED: To make both opposed cutting blades reciprocally move while waving so as to cut a hoop material having uneven front and back surfaces.SOLUTION: An upper ram 1 and a lower ram 2 are slidably provided between two bases A and B arranged in parallel. An upper blade 7 is fixed to the lower end of the upper ram 1, and a lower blade 8 to the upper end of the lower ram 2. An upper eccentric shaft 3 is provided at the upper end side of the upper ram 1, and a lower eccentric shaft 4 at the lower end side of the lower ram 2. By eccentrically rotating the upper eccentric shaft 3 and the lower eccentric shaft 4 in opposite directions mutually, the upper ram 1 and the lower ram 2 are moved swingingly forward and backward, to thereby cut the hoop material between the upper blade 7 and the lower blade 8.

Description

本発明は、フープ材を切断するカッターに関し、特に面に凹凸のあるフープ材のカッターに関する。   The present invention relates to a cutter for cutting a hoop material, and more particularly, to a cutter for a hoop material having an uneven surface.

従来のフープ材カッターには各種形式のものがあるが、多くのフープ材カッターは対向する刃物の一方が固定刃、他方が往復動する動刃になっており、この固定刃と動刃の間でフープ材を切断する方式である。これらのフープ材カッターは、例えば特許文献１に示される発明が公知である。
特許文献１の発明は、図3に示すように往復動するラム31の一端に固定された動刃32と本体33側に固定された固定刃34との間でフープ材35を切断する構成であり、図に示す表裏面に凹凸のないフープ材は問題なく切断することができるものである。 There are various types of conventional hoop material cutters, but many of the hoop material cutters have one of the opposed blades as a fixed blade and the other as a moving blade that reciprocates. In this method, the hoop material is cut. As for these hoop material cutters, for example, the invention disclosed in Patent Document 1 is known.
The invention of Patent Document 1 is configured to cut the hoop material 35 between a moving blade 32 fixed to one end of a reciprocating ram 31 and a fixed blade 34 fixed to the main body 33 side as shown in FIG. Yes, the hoop material having no irregularities on the front and back surfaces shown in the figure can be cut without any problem.

しかしながら、特許文献１に開示されたフープ材カッターは、例えば図4に示すように切断するフープ材36の表裏面に凹凸がある場合は、フープ材36の凸部37が刃物の端面に押圧されるためにねじれた状態で切断される。これにより切断されたフープ材の切り口がだれてしまうなどの問題がある。   However, in the hoop material cutter disclosed in Patent Document 1, for example, when the front and back surfaces of the hoop material 36 to be cut are uneven as shown in FIG. 4, the convex portion 37 of the hoop material 36 is pressed against the end surface of the cutter. For this purpose, it is cut in a twisted state. As a result, there is a problem that the cut end of the hoop material that has been cut is lost.

解決しようとする問題点は、従来のフープ材カッターは表裏面に凹凸のあるフープ材を切断することが困難なことである。   The problem to be solved is that it is difficult for a conventional hoop material cutter to cut a hoop material having irregularities on the front and back surfaces.

本発明は、表裏面に凹凸のあるフープ材を切断するために、対向する双方の刃物がウエイビングしつつ往復動して切断する構成にしたことを最も主要な特徴とする。   The main feature of the present invention is that, in order to cut a hoop material having irregularities on the front and back surfaces, both opposing blades are reciprocated and cut while waving.

本発明の両刃ウエイビングカッターは、対向する双方の刃物をウエイビングしつつ往復動する構成にしたことにより、フープ材の表裏面の凸部を刃物で押しつぶすことなく切断することができ、しかも切断されたフープ材の切り口にバリが発生しない正常な切断が可能になった。   The double-blade waving cutter of the present invention is configured to reciprocate while waving both opposing knives, so that the convex portions on the front and back surfaces of the hoop material can be cut without being crushed by the knives. It was possible to cut normally without burrs at the cut end of the hoop material.

は両刃ウエイビングカッターの構成を示す図である。These are figures which show the structure of a double-blade waving cutter. （a）（b）（c）は両刃ウエイビングカッターの構成およびフープ材導入から切断までの過程を示す図である。(A) (b) (c) is a figure which shows the process from the structure of a double-edged waving cutter and hoop material introduction | transduction to cutting | disconnection. は従来のフープ材カッターにて平坦なフープ材を切断する説明図である。These are explanatory drawings which cut | disconnect a flat hoop material with the conventional hoop material cutter. は従来のフープ材カッターにて両面に凹凸のあるフープ材を切断する説明図である。These are explanatory drawings which cut | disconnect the hoop material with an unevenness | corrugation on both surfaces with the conventional hoop material cutter.

表裏面に凹凸のあるフープ材を正常に切断するという目的を、対向する双方の刃物をウエイビングしつつ往復動する構成にて実現した。   The purpose of normally cutting the hoop material having irregularities on the front and back surfaces was realized by a structure that reciprocates while wavering both opposing blades.

図1および図2に示す本実施例の両刃ウエイビングカッターは、ベースAとベースBとの間に上部ラム1と下部ラム2が摺動自在に設けられており、上部ラム1の上端側にカム3aを有する上部偏心軸3が、下部ラム2の下端側にカム4aを有する下部偏心軸4が設けられている。更に、上部ラム1と下部ラム2それぞれにはガイドピン5と、ガイドピン5をガイドするガイド溝6が設けられ、上部ラム1の下端には上刃7が、下部ラム2の上端には下刃8のそれぞれが対向配置され、ボルト9,10にて固定されている。   In the double-blade waving cutter of this embodiment shown in FIGS. 1 and 2, an upper ram 1 and a lower ram 2 are slidably provided between a base A and a base B. An upper eccentric shaft 3 having a cam 3 a is provided, and a lower eccentric shaft 4 having a cam 4 a is provided on the lower end side of the lower ram 2. Further, the upper ram 1 and the lower ram 2 are each provided with a guide pin 5 and a guide groove 6 for guiding the guide pin 5, and an upper blade 7 is provided at the lower end of the upper ram 1 and a lower portion is provided at the upper end of the lower ram 2. Each of the blades 8 is disposed to face each other and is fixed by bolts 9 and 10.

上記構成の両刃ウエイビングカッターは、図示しないモータ駆動にて上部偏心軸3および下部偏心軸4を矢印AおよびBにて示す相反方向に回転することにより、上部ラム1および下部ラム2が、カム3aおよびカム4bの作用で遥動しかつガイドピン5とガイド溝6のガイドにより矢印CおよびDで示す対抗方向に往復動する。一方、図2に示すようにベースBの中央部にはホッパー11が設けられており、フープ材12がこのホッパー11を経て切断部に連続的に送り込まれる。   The double-blade waving cutter having the above-described configuration is configured such that the upper ram 1 and the lower ram 2 are camped by rotating the upper eccentric shaft 3 and the lower eccentric shaft 4 in opposite directions indicated by arrows A and B by a motor drive (not shown). It swings under the action of 3a and cam 4b, and reciprocates in the opposing direction indicated by arrows C and D by the guide of guide pin 5 and guide groove 6. On the other hand, as shown in FIG. 2, a hopper 11 is provided in the central portion of the base B, and the hoop material 12 is continuously fed into the cutting portion through the hopper 11.

例えば図2（a）に示すように、両面に凹凸のあるフープ材を切断する場合に、ホッパー11から送り込まれたフープ材12が切断部に送り込まれても、切断部では上刃7および下刃8が上下に開いた状態で、少なくとも上刃7および下刃8はホッパー25から上下に離れた位置にあり、フープ材12の凸部13が刃物に当接することはない。この状態で（b）図に示すように上刃7と下刃8がウエイビングしつつ上下方向からフープ材12に向かって進行し、（c）図に示すように上刃7と下刃8がフープ材12の凹部14に至り、刃物が凸部13に当接することなく切断することができる。なお上刃7および下刃8の厚さは凹部14の幅内に設定することにより凸部13に当接することを避けることができる。   For example, as shown in FIG. 2 (a), when a hoop material having unevenness on both sides is cut, even if the hoop material 12 sent from the hopper 11 is sent to the cutting portion, the upper blade 7 and the lower blade In a state where the blade 8 is opened up and down, at least the upper blade 7 and the lower blade 8 are located away from the hopper 25 in the vertical direction, and the convex portion 13 of the hoop material 12 does not contact the blade. In this state, as shown in (b), the upper blade 7 and the lower blade 8 travel from the vertical direction toward the hoop material 12 while waving, and (c) the upper blade 7 and the lower blade 8 move as shown in the drawing. It reaches the concave portion 14 of the hoop material 12, and the cutter can be cut without contacting the convex portion 13. The thicknesses of the upper blade 7 and the lower blade 8 can be set within the width of the concave portion 14 to avoid contact with the convex portion 13.

以上により本発明の両刃ウエイビングカッターは、フープ材12の表裏面の凸部13を刃物で押しつぶすことなく凹部14にて正常な切断をすることができ、しかも切断されたフープ材12の切り口にバリが発生しない。  As described above, the double-edged waving cutter of the present invention can perform normal cutting at the concave portion 14 without crushing the convex portion 13 on the front and back surfaces of the hoop material 12 with a blade, and at the cut end of the cut hoop material 12. No burr occurs.
