Description

本発明は、例えば、給水給湯配管に用いられる可撓性樹脂管を設定長さに切断する切断装置に関する。   The present invention relates to a cutting device that cuts a flexible resin pipe used for, for example, a water supply and hot water supply pipe into a set length.

従来より、住宅の給水給湯配管システムとして、給水主管および給湯主管をそれぞれ給水ヘッダーおよび給湯ヘッダーに接続する一方、ヘッダーからたこ足状に分岐させた給水分岐管および給湯分岐管を各設備機器の接続部に一対一で接続するヘッダー工法が採用されている。   Conventionally, as a hot water supply and hot water supply piping system for houses, a water supply main pipe and a hot water supply main pipe are connected to a water supply header and a hot water supply header, respectively. A header construction method is employed in which the parts are connected one-to-one.

具体的には、ヘッダー工法による配管システムは、住宅の床下空間に導かれた主管がヘッダーのヘッダー本体部に接続される一方、ヘッダーの各分岐接続部にそれぞれ分岐管が接続され、各分岐管が床下空間に巡らされて、各設備機器の接続部にそれぞれ接続されるものである。   Specifically, in the piping system based on the header construction method, the main pipe led to the under-floor space of the house is connected to the header main body of the header, while the branch pipes are connected to the respective branch connection parts of the header. Is circulated in the space under the floor and connected to the connection part of each equipment.

このようなヘッダー配管システムに使用される配管、特に、給水分岐管や給湯分岐管は、１住戸において使用される総延長が３０ｍを越える長さとなるため、巻物形態で施工現場に搬入されている。すなわち、分岐管としては、巻物として搬入可能な可撓性を有する配管、例えば、架橋ポリエチレン管やポリブデン管などの樹脂管がほとんどの場合で採用されている。   Piping used in such a header piping system, in particular, a water supply branch pipe and a hot water branch pipe have a total length exceeding 30 m in one dwelling unit, and are therefore carried into the construction site in the form of a scroll. . That is, as the branch pipe, a flexible pipe that can be carried in as a scroll, for example, a resin pipe such as a crosslinked polyethylene pipe or a polybden pipe is employed in most cases.

戸建て住宅におけるヘッダー配管システムの施工は、建物本体工事の工程を考慮して実施されている。最も多い形態のヘッダー配管システムの施工は、床下となる建物の基礎土間上にヘッダーを位置決めして固定し、ヘッダーに主管を接続した後、分岐管（可撓性樹脂管）を巻物から繰り出して設備機器側へ延長し、基礎土間に分岐管を固定するとともに、基礎土間から各設備機器の接続部である最終到達位置までの高さ分として、後の工程でできあがる床面の高さや設備機器内での立ち上げ高さを想定した上で、さらに１〜２ｍ程度の余裕をもって分岐管を切断する。   Construction of the header piping system in a detached house is carried out in consideration of the building body construction process. The most common form of header piping system is to position and fix the header on the foundation soil of the building under the floor, connect the main pipe to the header, and then feed the branch pipe (flexible resin pipe) out of the scroll Extend to the equipment side, fix the branch pipe between the foundation soil, and the height from the foundation soil to the final arrival position that is the connection part of each equipment, the floor height and equipment made in the subsequent process The branch pipe is further cut with a margin of about 1 to 2 m, assuming the startup height inside.

その後、建築工程が進み、床が形成された後にその床下地に貫通孔を開けて分岐管を挿通し、さらに、最終工程である設備機器の設置段階で、設備機器設置後に内部への分岐管接続が行われる。ここにおいて、設備機器の接続部に対して適切な長さに分岐管を切断することになる。このとき、１系統当たり１ｍ程度の余剰の管端部が廃棄物として発生し、戸建て住戸１棟分では１５ｍ程度に達する。   After that, after the building process has progressed and the floor has been formed, a through-hole is opened in the floor base and a branch pipe is inserted. Further, at the installation stage of the equipment that is the final process, the branch pipe to the inside after installation of the equipment A connection is made. Here, the branch pipe is cut to an appropriate length with respect to the connection portion of the equipment. At this time, an excess pipe end of about 1 m per system is generated as waste, and reaches about 15 m for one detached house.

このような余剰の管端部が廃棄物として発生する施工方法に対して、最近では、工場などにおいて、可撓性樹脂管を予め分岐管経路に沿う長さに切断して現場に持ち込む工法が提案されている。具体的には、図面検討の段階で、ヘッダー位置、設備機器の設置位置を検討し、図面上から必要な分岐管長さを把握し、把握された設定長さに可撓性樹脂管を切断して現場に提供するものである（例えば、特許文献１，２参照）。
ところで、工場などにおいて、可撓性樹脂管を設定長さに切断する際、切断面の直角度が確保されていない場合、つまり、切断面が垂直面に対して一定角度傾斜している場合、管継手への挿入、接続時に管継手のシール機構などに悪影響を及ぼして漏水事故などの原因となるおそれがある。したがって、可撓性樹脂管を切断するに際しては、切断面の直角度を確保する必要がある。 In contrast to a construction method in which such an excessive pipe end is generated as waste, recently, in a factory or the like, there is a construction method in which a flexible resin pipe is previously cut to a length along a branch pipe path and brought into the field. Proposed. Specifically, at the stage of drawing examination, examine the header position and installation position of equipment, grasp the necessary branch pipe length from the drawing, and cut the flexible resin pipe to the grasped set length. (See, for example, Patent Documents 1 and 2).
By the way, when cutting a flexible resin tube to a set length in a factory or the like, if the perpendicularity of the cut surface is not secured, that is, if the cut surface is inclined at a certain angle with respect to the vertical surface, When inserted into or connected to a pipe joint, it may adversely affect the seal mechanism of the pipe joint and cause a water leak. Therefore, when cutting the flexible resin tube, it is necessary to ensure the perpendicularity of the cut surface.

一方、可撓性樹脂管は、通常、巻物形態で保管されていることから、一定の巻き癖がついている。このような巻き癖がついている可撓性樹脂管を切断面の直角度を確保して切断する場合、通常、可撓性樹脂管を直線状に延ばして固定し、直線状の可撓性樹脂管に切断刃を直角に当てて切断するようにしているが、切断刃が可撓性樹脂管を切断している過程において、切断された部分から固定力が解放されることから、可撓性樹脂管の巻き癖に由来する反力によって切断部が変位する。このとき、切断刃に対して可撓性樹脂管の切断面の向きが変化し、切断面の直角度が確保されにくいという問題があった。   On the other hand, since the flexible resin tube is usually stored in the form of a scroll, it has a certain curl. When a flexible resin tube having such a curl is cut while ensuring the perpendicularity of the cut surface, the flexible resin tube is usually stretched and fixed in a straight line. The cutting blade is applied at a right angle to the tube for cutting. In the process of cutting the flexible resin tube by the cutting blade, the fixing force is released from the cut portion. The cutting part is displaced by the reaction force derived from the curl of the resin tube. At this time, there is a problem that the orientation of the cut surface of the flexible resin tube changes with respect to the cutting blade and it is difficult to ensure the perpendicularity of the cut surface.

そこで、巻物形態の可撓性樹脂管を支持して繰り出し可能な支持テーブルと、支持テーブルに支持された可撓性樹脂管を引き出す引き出し装置と、引き出し装置によって引き出された可撓性樹脂管の長さを測定する測長装置と、可撓性樹脂管を切断する切断刃と、引き出された可撓性樹脂管を巻き取る垂直軸回りに回転自在な巻き取り装置と、からなり、前記切断刃は、切断位置における可撓性樹脂管の巻き癖の曲率半径の接線に対して直交して配置された刃本体を有し、刃本体を前記接線に対して常に直交するように移動させて、巻き癖を維持して設定長さだけ引き出された可撓性樹脂管を切断するようにした切断装置が提案されている（特許文献３参照）。   Therefore, a support table capable of supporting and feeding a flexible resin tube in the form of a scroll, a drawer device for pulling out the flexible resin tube supported by the support table, and a flexible resin tube drawn by the drawer device are provided. The length measuring device for measuring the length, a cutting blade for cutting the flexible resin tube, and a winding device rotatable around a vertical axis for winding the drawn flexible resin tube, the cutting The blade has a blade body arranged perpendicular to the tangent of the radius of curvature of the flexible resin tube curl at the cutting position, and the blade body is moved so as to be always perpendicular to the tangent. There has been proposed a cutting device that cuts a flexible resin tube that has been drawn out for a set length while maintaining the curl (see Patent Document 3).

一方、昨今は、架橋ポリエチレン管などの可撓性樹脂管本体の周囲が発泡ポリエチレンや発泡ポリスチレンなどで形成された管状保温材で被覆された可撓性樹脂管（以下、「保温材付き管」と記す）を開発されている（例えば、積水化学工業社製の保温付エスロペックス）。
また、上記保温材付き管は、可撓性樹脂管本体の径が同じでも用途や使用場所に応じて保温材の肉厚が異なるものが複数種ある。したがって、保温材付き管の外径は、大径のものから小径のものまで多品種存在する。 On the other hand, recently, a flexible resin tube (hereinafter referred to as a “heat-insulating tube”) in which a flexible resin tube body such as a crosslinked polyethylene tube is covered with a tubular heat insulating material formed of foamed polyethylene or expanded polystyrene. (For example, Sropex with heat insulation manufactured by Sekisui Chemical Co., Ltd.).
Moreover, even if the said heat insulating material pipe | tube has the same diameter of a flexible resin pipe | tube main body, there exist multiple types from which the thickness of a heat insulating material differs according to a use or use place. Therefore, there are many types of outer diameters of the tubes with the heat insulating material, from those having a large diameter to those having a small diameter.

しかし、先に提案された上記公知文献３に記載の切断装置の場合、可撓性樹脂管の管外径差がそれほど大きくない範囲であれば、巻き癖のある可撓性樹脂管の管外径が変わっても、１台の切断装置で、切断された管はそのまま継手との接続などの使用に耐えるのであるが、切断しようとする可撓性樹脂管の外径の差が大きいと、１台の切断装置では対応しきれない。したがって、多品種少ロット生産を行うには、設備コストがかかりすぎるという問題がある。   However, in the case of the cutting apparatus described in the above-mentioned publicly known document 3, if the difference in the outside diameter of the flexible resin tube is not so large, the outside of the flexible resin tube with the curl Even if the diameter changes, with one cutting device, the cut tube can withstand use such as connection with a joint as it is, but if the difference in the outer diameter of the flexible resin tube to be cut is large, A single cutting device cannot handle it. Therefore, there is a problem that the equipment cost is too high to produce a large variety of products and a small lot.

本発明は、上記事情に鑑みて、巻き癖がついている場合であっても、１台で、外径の異なる多品種の可撓性樹脂管を、それぞれ切断面の直角度を確保して設定長さに切断することのできる可撓性樹脂管の切断装置を提供することを目的としている。   In view of the above circumstances, the present invention sets various types of flexible resin pipes having different outer diameters, each with a perpendicularity of the cut surface, even when a curl is attached. It aims at providing the cutting device of the flexible resin tube which can be cut | disconnected to length.

上記目的を達成するために、本発明にかかる可撓性樹脂管の切断装置(以下、「本発明の切断装置」と記す)は、長尺可撓性樹脂管を、長尺可撓性樹脂管の捩れを防止しながら移動可能に支持する支持ローラ対を、長尺可撓性樹脂管の切断位置を挟んで前記長尺可撓性樹脂管の移動方向の前後にそれぞれ有し、前記切断位置で切断刃を前記長尺可撓性樹脂管の刃が当たる部分の中心軸に直交する方向に移動させて前記長尺可撓性樹脂管を設定長さの可撓性樹脂管に切断する切断装置であって、切断時に長尺可撓性樹脂管の壁面を受けて前記切断刃から受ける力によって長尺可撓性樹脂管の切断方向への移動を抑える管受け面を有し、この管受け面に切断刃が通過するスリットを有する管受け部を備え、前記管受け部は、前記管受け面が、切断される長尺可撓性樹脂管の管外径に合わせて位置調整可能に設けられていることを特徴としている。   In order to achieve the above object, a flexible resin tube cutting device according to the present invention (hereinafter referred to as “the cutting device of the present invention”) is a long flexible resin tube. A pair of support rollers that are movably supported while preventing twisting of the tube are respectively provided in front of and behind the moving direction of the long flexible resin tube across the cutting position of the long flexible resin tube. The cutting blade is moved at a position in a direction perpendicular to the central axis of the portion where the blade of the long flexible resin tube abuts to cut the long flexible resin tube into a flexible resin tube having a set length. A cutting device having a tube receiving surface that receives a wall surface of a long flexible resin tube during cutting and suppresses movement of the long flexible resin tube in a cutting direction by a force received from the cutting blade.

すなわち、切断刃が刃先から刃元に向かって下方に傾斜し、長尺可撓性樹脂管方向に傾斜を保ちながら進退するように設けられているので、長尺可撓性樹脂管方向に移動するにつれて、前記傾斜によって、切断位置を下方に押さえるベクトルが働き、長尺可撓性樹脂管が切断されるまでしっかりと下方から受ける管受け面に押さえつけられて位置ずれが防止され、より安定した切断状態が得られる。 Although the cutting device of the present invention is not particularly limited, for example, in the cutting blade, the blade portion is inclined downward from the blade edge toward the blade base, and the blade portion is kept inclined in the direction of the long flexible resin tube.

That is, the cutting blade is inclined downward from the cutting edge toward the cutting edge, and is provided so as to advance and retreat while maintaining the inclination in the direction of the long flexible resin tube. As a result, the vector that presses the cutting position downward works due to the inclination, and the long flexible resin tube is firmly pressed against the tube receiving surface that is received from below until the long flexible resin tube is cut, thereby preventing the displacement and making it more stable. A cut state is obtained.

また、本発明の切断装置は、特に限定されないが、上記管受け面を、切断される長尺可撓性樹脂管の管外径に合う位置に移動させる管受け面移動手段を備えていることが好ましい。

上記管受け面移動手段としては、特に限定されないが、例えば、ラックとピニオンを用いたものや、油圧シリンダを用いたものなどが挙げられ、手動で操作できるものでも操作盤に設けたボタン操作によって自動で操作できるものでも構わない。
また、切断刃が上記のように刃先から刃元に向かってが下方に傾斜し、長尺可撓性樹脂管方向に前記傾斜を保ちながら進退するように設られている構成においては、管受け部を、長尺可撓性樹脂管を下方から受ける第１管受け面を有する第１受け部材と、前記長尺可撓性樹脂管を水平方向から受ける第２管受け面を有する第２受け部材とを有するとともに、

It may be one that can be operated automatically.
In the configuration in which the cutting blade is inclined downward from the cutting edge toward the cutting edge as described above and is advanced and retracted while maintaining the inclination in the direction of the long flexible resin tube, A first receiving member having a first tube receiving surface for receiving the long flexible resin tube from below, and a second receiving member having a second tube receiving surface for receiving the long flexible resin tube from the horizontal direction.

サプライ装置２は、図１および図２に示すように、複数の受けローラ２２と、複数の外側支柱２３および内側支柱２４を備えている。
複数の受けローラ２２は、図２に示すように、水平方向の回転軸を有し、この回転軸周りに回転自在となっているとともに、図１に示すように、架台２１の中心軸を中心にして放射状となるように架台２１に支持されている。 As shown in FIGS. 1 and 2, the supply device 2 includes a plurality of receiving rollers 22, a plurality of outer struts 23, and an inner strut 24.
The plurality of receiving rollers 22 have a horizontal rotation axis as shown in FIG. 2 and are rotatable around the rotation axis, and are centered on the central axis of the gantry 21 as shown in FIG. And supported by the gantry 21 so as to be radial.

複数の外側支柱２３および内側支柱２４は、それぞれ上記架台２１の中心軸を中心にした仮想円上に対となる外側支柱２３および内側支柱２４が同一半径上にそれぞれ並ぶように架台２１に支持されている。
すなわち、サプライ装置２は、巻物形状をした長尺可撓性樹脂管Ｐを外側支柱２３および内側支柱２４の間に上方から嵌め込むことによって、長尺可撓性樹脂管Ｐが複数の受けローラ２２に受けられる。そして、長尺可撓性樹脂管Ｐの管端を引き出すことによって長尺可撓性樹脂管Ｐが容易に回転するようになっている。 The plurality of outer struts 23 and inner struts 24 are supported by the gantry 21 so that the outer struts 23 and the inner struts 24 that are paired on a virtual circle centered on the central axis of the gantry 21 are arranged on the same radius. ing.
That is, the supply device 2 is configured such that the long flexible resin pipe P having a scroll shape is fitted between the outer support column 23 and the inner support column 24 from above so that the long flexible resin tube P has a plurality of receiving rollers. 22 is received. The long flexible resin tube P is easily rotated by pulling out the tube end of the long flexible resin tube P.

巻き取り機３は、回転台３１と、支持板３２と、ガイド板３３とを備えている。
回転台３１は、図１に示すように、平面視八角形をしていて、垂直方向の回転軸を有し、この回転軸が、図２に示すモータ３４によって回転するようになっている。 The winder 3 includes a turntable 31, a support plate 32, and a guide plate 33.
As shown in FIG. 1, the turntable 31 has an octagonal shape in plan view and has a vertical rotation axis, and this rotation axis is rotated by a motor 34 shown in FIG.

支持板３２は、回転台３１の八角形の各辺から外側に放射状に延出するように支持板３２の周縁部に一端部が固定されている。
ガイド板３３は、支持板３２の端縁から上方に延びるように支持板３２に下端部が固定されている。 One end of the support plate 32 is fixed to the peripheral edge of the support plate 32 so as to extend radially outward from each octagonal side of the turntable 31.
The lower end of the guide plate 33 is fixed to the support plate 32 so as to extend upward from the edge of the support plate 32.

また、巻き取り機３は、ガイド板３３の上端が、サプライ装置２の架台２１の下側に入り込むことが可能な高さに設定されている。
そして、詳細には図示しないが、サプライ装置２の架台２１は、巻き取り機３に対してそれらの中心間距離を調整できるように構成されている。 Further, the winder 3 is set to a height at which the upper end of the guide plate 33 can enter the lower side of the gantry 21 of the supply device 2.
Although not shown in detail, the gantry 21 of the supply device 2 is configured to be able to adjust the distance between the centers of the winder 3.

すなわち、長尺可撓性樹脂管Ｐの管径などによって巻き癖の曲率半径が変化したとしても、その曲率半径に合わせてサプライ装置２および巻き取り機３の切断装置本体１との相対位置を調整することができる。具体的には、サプライ装置２と巻き取り機３との中心間距離を小さくすれば、サプライ装置２から切断装置本体１を経て巻き取り機３にわたって巻回される可撓性樹脂管Ｐ１の曲率半径は小さくなり、逆にサプライ装置２と巻き取り機３との中心間距離を大きくすれば、サプライ装置２から切断装置本体１を経て巻き取り機３にわたって巻回される可撓性樹脂管Ｐ１の曲率半径は大きくなる。
なお、巻き取り機３は、ガイド板７３の上端が、サプライ装置２の架台２１の下側に入り込むことが可能な高さに設定されているので、サプライ装置２の架台２１の一部と上下方向で重なる位置まで移動させることができる。 That is, even if the radius of curvature of the curl changes depending on the diameter of the long flexible resin pipe P, the relative position of the supply device 2 and the cutting device body 1 of the winder 3 with the curvature radius is changed. Can be adjusted. Specifically, if the distance between the centers of the supply device 2 and the winder 3 is reduced, the curvature of the flexible resin pipe P1 wound around the winder 3 from the supply device 2 through the cutting device body 1 is obtained. If the radius becomes smaller and conversely the distance between the centers of the supply device 2 and the winder 3 is increased, the flexible resin tube P1 wound around the winder 3 from the supply device 2 through the cutting device main body 1. The radius of curvature increases.
In addition, since the upper end of the guide plate 73 is set to a height at which the upper end of the guide plate 73 can enter the lower side of the gantry 21 of the supply device 2, It can be moved to a position that overlaps in the direction.

つぎに、この切断装置Ａを用いた長尺可撓性樹脂管Ｐの切断手順および各部の動作を詳しく説明する。   Next, the cutting procedure of the long flexible resin pipe P using the cutting apparatus A and the operation of each part will be described in detail.

（１）サプライ装置２と巻き取り機３の位置を切断しようとする長尺可撓性樹脂管Ｐの巻き癖の曲率半径や外径に応じて予め設定された位置に配置するとともに、巻物形態の長尺可撓性樹脂管Ｐをサプライ装置２にセットする。
すなわち、このセットによって、長尺可撓性樹脂管Ｐは、巻物中心軸を垂直方向に向け、内側支柱２４が芯となるように上方から落とし込んで受けローラ２２に巻物の下面側を受けさせてサプライ装置２に巻物中心軸周りに回転自在に支持される。 (1) The supply device 2 and the winder 3 are arranged at positions set in advance according to the radius of curvature and outer diameter of the winding rod of the long flexible resin tube P to be cut, and the scroll form The long flexible resin tube P is set in the supply device 2.
That is, by this set, the long flexible resin tube P is dropped from above so that the center axis of the scroll is in the vertical direction and the inner column 24 is the core, and the receiving roller 22 receives the lower surface side of the scroll. The supply device 2 is supported so as to be rotatable around the scroll central axis.

（２）巻物から長尺可撓性樹脂管Ｐの外側の端を引き出し、切断装置本体１のところまで導き、送り出し手段４の駆動ローラ４１と従動プーリ４２との間、第１ガイド手段５ａの従動ローラ５１と従動プーリ５２との間、第２ガイド手段の従動ローラ５１と従動プーリ５２との間を通り少し巻き取り機３側に出たところまで通す。 (2) Pull out the outer end of the long flexible resin tube P from the roll, guide it to the cutting device body 1, and between the driving roller 41 of the delivery means 4 and the driven pulley 42, the first guide means 5a Pass between the driven roller 51 and the driven pulley 52, between the driven roller 51 and the driven pulley 52 of the second guide means, and slightly pass to the position where it comes out to the winder 3 side.

（３）制御盤（図示せず）で管径の設定ボタンを押す。
すなわち、この設定ボダンを押すことによって油圧シリンダ４３が作動して設定された管径に応じた距離だけ従動プーリ４２を駆動ローラ４１側に移動させ、駆動ローラ４１の回転駆動によって長尺可撓性樹脂管Ｐが第１ガイド手段５ａ側に送られるとともに、それに伴い従動プーリ４２がスリップなく従動するようになる。
また、同時に第１ガイド手段５ａおよび第２ガイド手段５ｂの油圧シリンダ５３が作動して管径に応じた距離だけ従動プーリ５２を従動ローラ５１側に移動させ、送り出し手段４による長尺可撓性樹脂管Ｐの送り出しに伴って、従動プーリ５２および従動ローラ５１が従動するようになる。
そして、長尺可撓性樹脂管Ｐは、巻き癖に応じた曲率半径をほぼ保った湾曲形状に保たれた状態、すなわち、捩れがない状態で送り出し手段４、第１ガイド５ａおよび第２ガイド手段５ｂによって支持された状態を保つ。
一方、切断機６は、切断刃６１が油圧シリンダ６２のピストンが縮退した状態（以下「刃初期状態」と記す）に配置され、第１受け部材７ａは、第１管受け面７１が第１ガイド手段５ａおよび第２ガイド手段５ｂ間で支持された長尺可撓性樹脂管Ｐの下端にほぼ触れるような近接位置に配置される。
第２管受け部材７ｂは、油圧シリンダ７４のピストンが縮退した状態（以下「初期状態」と記す）に配置される。 (3) Press the tube diameter setting button on the control panel (not shown).
That is, by pushing the setting body, the hydraulic cylinder 43 is actuated to move the driven pulley 42 toward the driving roller 41 by a distance corresponding to the set tube diameter, and the long flexibility is driven by the rotation of the driving roller 41. While the resin pipe P is sent to the first guide means 5a side, the driven pulley 42 is driven without slipping.
At the same time, the hydraulic cylinders 53 of the first guide means 5a and the second guide means 5b are operated to move the driven pulley 52 to the driven roller 51 side by a distance corresponding to the pipe diameter, and the long flexible by the delivery means 4 is achieved. As the resin pipe P is delivered, the driven pulley 52 and the driven roller 51 are driven.
The long flexible resin pipe P is kept in a curved shape substantially maintaining the radius of curvature corresponding to the curl, that is, in a state where there is no twist, the delivery means 4, the first guide 5a and the second guide. The state supported by the means 5b is maintained.
On the other hand, in the cutting machine 6, the cutting blade 61 is disposed in a state where the piston of the hydraulic cylinder 62 is retracted (hereinafter referred to as “blade initial state”), and the first receiving member 7a has the first tube receiving surface 71 as the first. It arrange | positions in the proximity position which touches the lower end of the long flexible resin pipe P supported between the guide means 5a and the 2nd guide means 5b substantially.
The second pipe receiving member 7b is disposed in a state where the piston of the hydraulic cylinder 74 is retracted (hereinafter referred to as “initial state”).

（４）操作盤の予備切断スイッチ（図示せず）を押す。
切断スイッチを押すことによって、第２管受け部材７ｂが油圧シリンダ７４の作動によって長尺可撓性樹脂管Ｐにほぼ接触する位置まで進出するとともに、切断機６の切断刃６１が油圧シリンダ６２の作動により第２管受け部材７ｂ方向に進出し、長尺可撓性樹脂管Ｐを予備切断する。
すなわち、切断刃６１は、まず、刃部６１ａの刃先側が長尺可撓性樹脂管Ｐの壁面に当接し、第２管受け部材７ｂ側に進出するのにともない、長尺可撓性樹脂管Ｐをする刃部６１ａで切断していくが、。刃部６１ａが刃先から刃元に向かって下方に傾斜するので、切断刃６１が第２管受け部材７ｂ側に進出するにつれ刃部６１ａの傾斜によって長尺可撓性樹脂管Ｐの切断残部が第１管受け面７１側に押圧される。したがって、長尺可撓性樹脂管Ｐが切断に伴って浮き上がったり位置ずれしたりすることなく切断位置の管本体の中心軸にほぼ長尺可撓性樹脂管Ｐの曲率半径の接線に直交する切断面に切断される。
しかも、長尺可撓性樹脂管Ｐの切断刃進出方向の動きも第２管受け部材７ｂによって規制され、より確実に管本体の中心軸に直交する切断面に切断される。
なお、上記ほぼ長尺可撓性樹脂管Ｐの曲率半径の接線に直交するとは、可撓性樹脂管Ｐ１を施工現場で継手に接続する場合に接続可能な程度の傾斜状態を含むことを意味する。 (4) Press a preliminary cut switch (not shown) on the operation panel.
By pushing the cutting switch, the second tube receiving member 7b moves to a position where it substantially contacts the long flexible resin pipe P by the operation of the hydraulic cylinder 74, and the cutting blade 61 of the cutting machine 6 moves to the position of the hydraulic cylinder 62. By operation, it advances in the direction of the second pipe receiving member 7b, and the long flexible resin pipe P is preliminarily cut.
That is, the cutting blade 61 first has a long flexible resin tube as the cutting edge side of the blade portion 61a comes into contact with the wall surface of the long flexible resin tube P and advances toward the second tube receiving member 7b. Although it cuts with the blade part 61a which does P ,. Since the blade portion 61a is inclined downward from the blade edge toward the blade base, the cutting remainder of the long flexible resin pipe P is caused by the inclination of the blade portion 61a as the cutting blade 61 advances toward the second tube receiving member 7b. It is pressed to the first tube receiving surface 71 side. Therefore, the long flexible resin tube P is not substantially lifted or displaced due to cutting, and is substantially perpendicular to the tangent to the radius of curvature of the long flexible resin tube P at the central axis of the tube body at the cutting position. Cut into cut surfaces.
In addition, the movement of the long flexible resin pipe P in the cutting blade advance direction is also regulated by the second pipe receiving member 7b, and the long flexible resin pipe P is more reliably cut into a cut surface perpendicular to the central axis of the pipe body.
In addition, being orthogonal to the tangent of the radius of curvature of the substantially long flexible resin pipe P means that it includes an inclined state that can be connected when the flexible resin pipe P1 is connected to a joint at a construction site. To do.

（５）制御盤で測長長さ（得ようとする可撓性樹脂管Ｐ１の長さ）をセットしたのち、切断スイッチ（図示せず）を押す。
予備切断スイッチが押されると、モータ４４が駆動して駆動ローラ４１が回転駆動し、送り出し手段４によってサプライ装置２側の長尺可撓性樹脂管Ｐが引き出されながら第１ガイド手段５ａおよび第２ガイド手段５ｂを経て巻き取り機３側に送り出される。同時に、ロータリーエンコーダ４５により測長が開始される。 (5) After setting the measurement length (the length of the flexible resin pipe P1 to be obtained) on the control panel, a disconnect switch (not shown) is pushed.
When the pre-cutting switch is pressed, the motor 44 is driven to drive the drive roller 41 to rotate, and the long flexible resin pipe P on the supply device 2 side is pulled out by the delivery means 4 while the first guide means 5a and the first guide means 5a. It is sent out to the winder 3 side through the two guide means 5b. At the same time, length measurement is started by the rotary encoder 45.

（６）制御盤で巻き取り機３の電源スイッチ（図示せず）を入れ、巻き取り機３を回転させるとともに、第２ガイド手段５ｂを経て送り出されてきた長尺可撓性樹脂管Ｐの端部を係止部（図示せず）に係止させ、送り出されてくる長尺可撓性樹脂管Ｐを順次巻き込ませる。 (6) The power switch (not shown) of the winder 3 is turned on with the control panel, the winder 3 is rotated, and the long flexible resin pipe P sent out through the second guide means 5b The end portion is locked to a locking portion (not shown), and the long flexible resin pipe P that is fed out is sequentially wound.

（７）ロータリーエンコーダ４５によって測長された長さが設定長さに達すると、自動的にモータ４４が停止するとともに、巻き取り機３も停止する。なお、測長は、従動プーリ４２と切断刃６１の切断位置までの長さが固定値として予め制御装置に入力されており、可撓性樹脂管Ｐの長さが、切断刃６１の刃本体５１によって予備切断された長尺可撓性樹脂管Ｐの端縁部を始点として測定されるようになっている。 (7) When the length measured by the rotary encoder 45 reaches the set length, the motor 44 automatically stops and the winder 3 also stops. In the length measurement, the lengths of the driven pulley 42 and the cutting blade 61 up to the cutting position are previously input to the control device as fixed values, and the length of the flexible resin tube P is the blade body of the cutting blade 61. Measurement is made with the end of the long flexible resin tube P preliminarily cut by 51 as the starting point.

（８）制御盤の切断スイッチ（図示せず）を押す。
切断スイッチが押されることによって予備切断と同様にして長尺可撓性樹脂管Ｐが切断刃６１によって切断され、切断刃６１から巻き取り機３側に設定された長さの可撓性樹脂管Ｐ１が残る。
なお、切断刃６１は切断完了後、自動的に刃初期状態に戻り、第２管受け部材７ｂも初期状態に戻る。 (8) Press the control panel disconnect switch (not shown).
When the cutting switch is pressed, the long flexible resin tube P is cut by the cutting blade 61 in the same manner as the preliminary cutting, and the flexible resin tube having a length set from the cutting blade 61 to the winder 3 side. P1 remains.
The cutting blade 61 automatically returns to the initial blade state after the cutting is completed, and the second pipe receiving member 7b also returns to the initial state.

（９）再び制御盤で巻き取り機３をで巻き取り機３の電源スイッチ（図示せず）を入れ、巻き取り機３を回転させ可撓性樹脂管Ｐ１の巻き取り機３に巻き取られていない部分を巻き取り機３に巻き取って巻物状にして結束する。 (9) The power switch (not shown) of the winder 3 is turned on again with the control panel, and the winder 3 is rotated to be wound around the winder 3 of the flexible resin tube P1. The part which is not wound is wound up on the winder 3 to be wound up and bound.

（１０）サプライ装置２側に巻物状態の長尺可撓性樹脂管Ｐが残っている限り、（６）〜（９）の工程を繰り返し、つぎつぎに設定された長さの可撓性樹脂管Ｐ１を得る。 (10) As long as the long flexible resin pipe P in a wound state remains on the supply device 2 side, the steps (6) to (9) are repeated, and the flexible resin pipe having a set length is successively set. Obtain P1.

この切断装置Ａは、上記のように、第１受け部材７ａが昇降し、切断される長尺可撓性樹脂管の外径が変わってもつねに切断刃６１によって長尺可撓性樹脂管Ｐが切断される際に長尺可撓性樹脂管Ｐがずれ動かないように、また、長尺可撓性樹脂管Ｐに切断を阻害するようない変形を与えずに下端が第１受け部材７ａの第１管受け面７１に常に受けられた状態に保持される。また、長尺可撓性樹脂管Ｐは、巻き癖の曲率半径を保った状態に第１ガイド手段５ａおよび第２カイド手段５ｂに支持され、切断刃６１が水平方向に移動するので、巻き癖があっても、切断位置で刃先が切断位置の長尺可撓性樹脂管Ｐの曲率半径の接線に直交するように切断を開始する。そして、切断刃６１の刃部６１ａが傾斜しているので、切断刃６１の第２管受け部材７ｂ側への進出に伴って、長尺可撓性樹脂管Ｐの切断残部を第１受け部材７ａの第１管受け面７１に押し付けながら切断していく。したがって、長尺可撓性樹脂管Ｐが可撓管本体の周囲に保温材を備えたものであっても、ずれ動くことなく切断される。すなわち、巻き癖の曲率半径の接線に直交する切断面を備えた可撓性樹脂管Ｐ１を安定して得ることができる。
また、第１受け部材７ａが昇降可能で第２管受け部材７ｂが切断刃６１方向に進退自在になっているので、管径の異なるいろいろな長尺可撓性樹脂管Ｐを巻き癖の曲率半径の接線に直交する切断面を備えた可撓性樹脂管Ｐ１に切断することができる。 As described above, in the cutting device A, the first receiving member 7a is moved up and down, and the outer diameter of the long flexible resin tube to be cut is changed, so that the long flexible resin tube P is always cut by the cutting blade 61. The long flexible resin tube P does not move when the tube is cut, and the lower end of the first flexible resin tube P is not deformed so as not to hinder the cutting. The first pipe receiving surface 71 is always held in the received state. Further, the long flexible resin tube P is supported by the first guide means 5a and the second guide means 5b while maintaining the curvature radius of the curl, and the cutting blade 61 moves in the horizontal direction. Even if there is, the cutting is started so that the cutting edge is orthogonal to the tangent of the radius of curvature of the long flexible resin pipe P at the cutting position. And since the blade part 61a of the cutting blade 61 is inclined, as the cutting blade 61 advances toward the second tube receiving member 7b, the remaining cutting portion of the long flexible resin tube P is transferred to the first receiving member. It cut | disconnects, pressing against the 1st pipe | tube receiving surface 71 of 7a. Therefore, even if the long flexible resin tube P is provided with a heat insulating material around the flexible tube main body, it is cut without moving. That is, it is possible to stably obtain the flexible resin pipe P1 having a cut surface perpendicular to the tangent line of the curvature radius of the curl.
In addition, since the first receiving member 7a can be moved up and down and the second tube receiving member 7b can be moved forward and backward in the direction of the cutting blade 61, various long flexible resin tubes P having different tube diameters are wound. It can cut | disconnect to the flexible resin pipe P1 provided with the cut surface orthogonal to the tangent of a radius.

That is, the length of the long flexible resin tube can be measured by the number of rotations of the stepping motor.
In the above embodiment, the long flexible resin tube in the form of a scroll is cut into a flexible resin tube having a set length, but it is adjacent to the molding device for the long flexible resin tube. The cutting device main body may be arranged, and the long flexible resin tube that is extruded may be directly cut to obtain a flexible resin tube having a set length.
