And picking up and cutting with a cutting means. The take-up mechanism is composed of a pair of upper and lower endless belts. The take-up speed of the take-up mechanism is a molding speed line of the thermoplastic resin extruded from the die of the extruder.

また、特許文献3には、コルゲートチューブの切断装置として、上下一対の無端の送出ベルトでなるチューブ送出機構部と、チューブ送出機構部に隣接するガイド機構部と、ガイド機構部に隣接する切断機構部とで構成されるものが記載されている。ガイド機構部は、上下各一対のガイドローラと、一対のガイドローラの上又は下に配置された各同期用プーリと、一対のガイドローラと同期用プーリとに略三角形状に掛け渡されたタイミングベルトとで構成されている。   Further, in Patent Document 3, as a corrugated tube cutting device, a tube delivery mechanism unit composed of a pair of upper and lower endless delivery belts, a guide mechanism unit adjacent to the tube delivery mechanism unit, and a cutting mechanism adjacent to the guide mechanism unit What is composed of parts is described.

The corrugated tube is an existing tube in which annular convex portions and annular concave portions are arranged at equal pitches in the longitudinal direction and with a uniform outer diameter.

図3は、従来のコルゲートチューブの引取装置を含むコルゲートチューブの製造装置の一形態を示すものである。   FIG. 3 shows an embodiment of a corrugated tube manufacturing apparatus including a conventional corrugated tube take-up device.

コルゲートチューブ51は、周方向の凸条(山部)51aと凹溝(谷部)51bを長手方向に等ピッチで配列した屈曲自在なものであり、不図示の押出装置から溶融樹脂材を成形装置52に供給し、成形装置52の上下の無限軌道状に連結された複数の金型53で蛇腹形状に成形し、複数の金型53の回転動作で送り出し、弛み検出用のアキュムレータ54を経て、引取装置55の上下の無端ベルト56の回転で引き取っている。   The corrugated tube 51 is a flexible tube in which circumferential ridges (peaks) 51a and grooves (valleys) 51b are arranged at equal pitches in the longitudinal direction, and a molten resin material is molded from an unillustrated extrusion device. A plurality of molds 53 connected to the upper and lower endless tracks of the molding apparatus 52 are molded into a bellows shape, sent out by the rotation of the plurality of molds 53, and passed through an accumulator 54 for detecting slack. The upper and lower endless belts 56 of the take-up device 55 take up the rotation.

コルゲートチューブ51の凹凸状の蛇腹部の肉厚は例えば0.3mm程度と薄く、コルゲートチューブ51は成形装置52の出口において十分に冷えているので、弛ませても変形を生じることはない。成形装置52と引取装置55との間にアキュムレータ54を配置し、引取装置55が成形装置52に完全に同調しなくても、コルゲートチューブ(製品)51に悪影響を生じることはない。   The thickness of the corrugated bellows portion of the corrugated tube 51 is as thin as, for example, about 0.3 mm, and the corrugated tube 51 is sufficiently cooled at the outlet of the molding device 52, so that deformation does not occur even if it is slackened. Even if the accumulator 54 is disposed between the forming device 52 and the take-up device 55 and the take-up device 55 is not completely synchronized with the forming device 52, the corrugated tube (product) 51 is not adversely affected.

しかしながら、上記図3を用いて説明したコルゲートチューブの製造方法にあっては、ストレート管部と蛇腹管部とを有する部分成形コルゲートチューブ(異径チューブ)の製造に際しては、蛇腹管部とストレート管部との外径が異なり、さらにストレート管部の肉厚が蛇腹管部の肉厚よりも厚く、成形装置52の出口では製品温度が高いために、引取装置55で製品(部分成形コルゲートチューブ)を引っ張り過ぎると、製品の肉厚が薄くなって長手方向に伸び、製品が弛むと変形や反りを生じて、既存の引取装置55では上手く引き取ることができないという問題を生じてしまう。   However, in the method for manufacturing a corrugated tube described with reference to FIG. 3 above, when manufacturing a partially formed corrugated tube having a straight tube portion and a bellows tube portion (different diameter tube), the bellows tube portion and the straight tube. Since the outer diameter of the straight tube portion is different from the thickness of the bellows tube portion and the product temperature is higher at the outlet of the forming device 52, the product (partially formed corrugated tube) is used in the take-up device 55. If the product is pulled too much, the thickness of the product becomes thin and extends in the longitudinal direction. When the product is loosened, deformation or warping occurs, and the existing take-up device 55 cannot take it out.

本発明は、上記した点に鑑み、部分成形コルゲートチューブ等といった異径チューブを、有害な伸びや変形・反り等を生じることなく、確実にまたスムーズに引き取ることのできる異径チューブの引取装置及び引取方法を提供することを目的とする。   In view of the above points, the present invention provides a different diameter tube take-out device that can reliably and smoothly take off different diameter tubes such as partially molded corrugated tubes without causing harmful elongation, deformation, warpage, etc. The purpose is to provide a pick-up method.

For example, the pair of front belt drive units grips (holds) the large-diameter portion of the different diameter tube, and at the same time, the pair of belt drive units on the rear side grips (holds) the small-diameter portion. Regardless of a slight time loss due to the swing of the pair of belt drive units, the pair of belt drive units on the front side reliably pulls the different-diameter tubes.

図1の如く、この異径チューブの製造装置1は、異径チューブ6の製造工程順に、押出装置2と、成形装置3と、冷却装置4と、引取装置5とを備えている。なお、押出装置2を押出機、成形装置3を成形機、冷却装置4を冷却機、引取装置5を引取機と呼称する場合もある。   As shown in FIG. 1, the different diameter tube manufacturing apparatus 1 includes an extrusion device 2, a forming device 3, a cooling device 4, and a take-up device 5 in the order of manufacturing steps of the different diameter tube 6. The extrusion device 2 may be referred to as an extruder, the molding device 3 as a molding machine, the cooling device 4 as a cooling machine, and the take-up device 5 as a take-up machine.

異径チューブ6は、合成樹脂製の部分成形コルゲートチューブであり、剛性の小径なストレート管部(小径部)7と屈曲性の大径な蛇腹管部(大径部)8とをチューブ長手方向に交互に配列して構成される。ストレート管部7の肉厚は厚く、蛇腹管部8の肉厚は薄く形成されている。例えば、ストレート管部7は勿論のこと、蛇腹管部8も径方向の圧縮に対して潰れ変形しにくい肉厚を有している。部分成形とは、部分的に蛇腹管部8を成形したという意味である。   The different-diameter tube 6 is a partially molded corrugated tube made of synthetic resin, and includes a rigid small-diameter straight tube portion (small-diameter portion) 7 and a flexible large-diameter bellows tube portion (large-diameter portion) 8 in the longitudinal direction of the tube. Are arranged alternately. The straight tube portion 7 is thick, and the bellows tube portion 8 is thin. For example, not only the straight tube portion 7 but also the bellows tube portion 8 has a thickness that is difficult to be crushed and deformed due to radial compression. Partial molding means that the bellows tube portion 8 is partially molded.

押出装置2は、既存のものであり、熱可塑性樹脂材のペレットをホッパ9に供給して、装置内部で加熱溶融(軟化)させ、螺旋状の押出部10を回転させて、軟化樹脂材を押出部10から前方のノズル(ダイ)11を経てチューブ状にして成形装置3に押し出して供給する。   The extrusion apparatus 2 is an existing one, and supplies pellets of thermoplastic resin material to the hopper 9 and is heated and melted (softened) inside the apparatus, and the helical extrusion portion 10 is rotated to obtain the softened resin material. From the extruding unit 10, it passes through a nozzle (die) 11 in the front and is formed into a tube shape and extruded and supplied to the molding apparatus 3.

成形装置3は、部分成形コルゲートチューブ6の蛇腹管部8を成形する金型12と、ストレート管部7を成形する金型13とを交互に配置して、無限軌道状に連続させた連鎖金型14を上下に対称に配設して、互いに矢印の如く逆方向に回転駆動させるものである。上側の連鎖金型14を矢印Aの如く反時計回りに回転させると同時に、下側の連鎖金型14を矢印A’の如く時計回りに回転させて、押出措置2で供給された入口側のチューブ状の軟化樹脂材を、ストレート管部7と蛇腹管部8とで成る部分成形コルゲートチューブ6に成形して、出口側から冷却装置4や引取装置5に向けて前方に送出する。   The molding apparatus 3 is a chain metal mold in which a mold 12 that molds the bellows tube portion 8 of the partially molded corrugated tube 6 and a mold 13 that molds the straight tube portion 7 are alternately arranged to be continuous in an endless track shape. The molds 14 are arranged symmetrically in the vertical direction and are driven to rotate in opposite directions as indicated by arrows. The upper chain die 14 is rotated counterclockwise as indicated by an arrow A, and simultaneously the lower chain die 14 is rotated clockwise as indicated by an arrow A ′ so A tube-shaped softened resin material is formed into a partially formed corrugated tube 6 composed of a straight tube portion 7 and a bellows tube portion 8 and fed forward from the outlet toward the cooling device 4 and the take-up device 5.

本例の部分成形コルゲートチューブ6は、蛇腹管部8とストレート管部7とを不等間隔で配置し、且つ蛇腹管部8とストレート管部7の各長さも不均一に設定しており、上下の連鎖金型14の一回転ごとに、同じ配列形状の部分成形コルゲートチューブ6を成形する。完成した部分成形コルゲートチューブ6は各蛇腹管部8において三次元方向に屈曲して使用される。なお、蛇腹管部8とストレート管部7との各長さや間隔は必要に応じて適宜設定される。部分成形コルゲートチューブ6は、引取装置5の後工程の不図示の切断装置で、所要長さに径方向に切断されて製品化される。   In the partially molded corrugated tube 6 of this example, the bellows tube portion 8 and the straight tube portion 7 are arranged at unequal intervals, and the lengths of the bellows tube portion 8 and the straight tube portion 7 are also set unevenly, For each rotation of the upper and lower chain molds 14, the partially molded corrugated tubes 6 having the same array shape are formed. The completed partially molded corrugated tube 6 is bent in the three-dimensional direction at each bellows tube portion 8 and used. In addition, each length and space | interval of the bellows pipe part 8 and the straight pipe part 7 are set suitably as needed. The partially molded corrugated tube 6 is cut into a required length in the radial direction by a cutting device (not shown) in the subsequent process of the take-up device 5 to be commercialized.

蛇腹管部成形用の金型12は断面円弧状の溝部(図示せず)の内面に蛇腹形状の凹凸(図示せず)を有しており、ストレート管部形成用の金型13は、蛇腹管部成形用の金型12の溝部よりも小径な断面円弧状の溝部(図示せず)を有している。蛇腹管部8やストレート管部7の長さに応じて、複数の隣接する金型12,13にこれら溝部が連続して形成されている。   The bellows tube forming die 12 has bellows-shaped irregularities (not shown) on the inner surface of a groove portion (not shown) having an arc cross section, and the straight tube portion forming die 13 is a bellows. A groove portion (not shown) having an arcuate cross-section having a smaller diameter than the groove portion of the mold 12 for forming the tube portion is provided. Depending on the length of the bellows tube portion 8 and the straight tube portion 7, these groove portions are continuously formed in a plurality of adjacent molds 12 and 13.

冷却装置4は、成形装置3の出口から送出された高温度の部分成形コルゲートチューブ6を素早く冷却させるためのものである。引取装置5で部分成形コルゲートチューブ6を引き取る前に、部分成形コルゲートチューブ6を冷却装置4で十分に冷やして、引き取り時の変形等を生じないようにする。冷却は、例えば冷気の強制送風等で効率的に行うことができる。   The cooling device 4 is for quickly cooling the high temperature partially molded corrugated tube 6 delivered from the outlet of the molding device 3. Before the partially molded corrugated tube 6 is taken up by the take-up device 5, the partially molded corrugated tube 6 is sufficiently cooled by the cooling device 4 so as not to be deformed at the time of taking-up. The cooling can be efficiently performed by, for example, forced air blowing of cold air.

成形装置3から冷却装置4を経て引取装置5に至る部分成形コルゲートチューブ6の送り方向は水平方向で且つ真直であり、成形装置3と引取装置5との間で、部分成形コルゲートチューブ6は弛むことなく真直に引取装置5によって引き取られる。   The feeding direction of the partially molded corrugated tube 6 extending from the forming device 3 through the cooling device 4 to the take-up device 5 is horizontal and straight, and the partially formed corrugated tube 6 is loosened between the forming device 3 and the take-up device 5. It is taken up straight by the take-up device 5 without.

引取装置5のチューブ引取速度は成形装置3のチューブ送出速度と等しくなるように規定されている。引取装置5による部分成形コルゲートチューブ6の引取動作は、成形装置3による部分成形コルゲートチューブ6の成形動作すなわち送出動作に常に同期して(連動して)行われるように、不図示の制御装置で制御されている。   The tube take-up speed of the take-up device 5 is defined to be equal to the tube delivery speed of the forming device 3. The take-up operation of the partially molded corrugated tube 6 by the take-up device 5 is performed by a control device (not shown) so that it is always performed in synchronization (interlocking) with the forming operation of the partially-formed corrugated tube 6 by the forming device 3, ie, the feeding operation. It is controlled.

引取装置5は、図1の如く、装置本体(フレーム)15の水平な底壁16と垂直な左右一対の側壁17(図1では奥側の側壁のみを図示している)とを有し、左右一対の側壁17の間に、図1,図2の如く、部分成形コルゲートチューブ6を挟んで引っ張るための、上下各一対、計二対(四つ)のベルト駆動部18,18’,19,19’を有している。   As shown in FIG. 1, the take-up device 5 has a pair of left and right side walls 17 (only the back side wall is shown in FIG. 1) that is perpendicular to the horizontal bottom wall 16 of the apparatus body (frame) 15. As shown in FIGS. 1 and 2, a pair of upper and lower belt drive units 18, 18 ′, 19 for pulling the partially molded corrugated tube 6 as shown in FIGS. 1 and 2. , 19 ′.

図2の如く、各ベルト駆動部18〜19’は、前後一対のプーリ(ガイドプーリ)20,21と、前後一対のプーリ20,21の上側又は下側に配置された一つのプーリ(駆動プーリ)22との、計三つのプーリ20〜22を三角形状の各角部に位置するように配置し、三つのプーリ20〜22の外周側に各駆動ベルト23を略三角形状になるように掛け渡し、駆動プーリ22と同軸(同心)に、駆動プーリ22に一体的に固定された駆動ギア24を設けて構成されている。駆動ベルト23は内周面に凹凸の歯部(図示せず)を有するタイミングベルトであり、各プーリ20〜22は外周面に凹凸の歯部(図示せず)を有するタイミングプーリである。   As shown in FIG. 2, each belt drive unit 18 to 19 ′ includes a pair of front and rear pulleys (guide pulleys) 20 and 21, and one pulley (drive pulley) disposed above or below the pair of front and rear pulleys 20 and 21. ) 22 and a total of three pulleys 20 to 22 are arranged so as to be located at each corner of the triangle shape, and each drive belt 23 is hung on the outer peripheral side of the three pulleys 20 to 22 so as to be substantially triangular. A drive gear 24 that is integrally fixed to the drive pulley 22 is provided coaxially (concentrically) with the drive pulley 22. The driving belt 23 is a timing belt having an uneven tooth portion (not shown) on the inner peripheral surface, and the pulleys 20 to 22 are timing pulleys having an uneven tooth portion (not shown) on the outer peripheral surface.

そして、前後の駆動ギア24,24の間に大径な共通の駆動ギア25が配置され、共通の駆動ギア25は共通(一つ)の不図示のサーボモータで同時に駆動される。サーボモータは前記成形装置3の連鎖金型14の送り動作と同期して回転する。上下の共通の駆動ギア25の矢印B,B’方向の回転動作で、上側の各ベルト駆動部18,19の前後の駆動ギア24及び駆動プーリ22が矢印Cの如く反時計回りに回転駆動され、且つ下側の各ベルト駆動部18’,19’の前後の駆動ギア24及び駆動プーリ22が矢印C’の如く時計回りに回転駆動される。   A large common drive gear 25 is arranged between the front and rear drive gears 24, 24, and the common drive gear 25 is simultaneously driven by a common (one) servo motor (not shown). The servo motor rotates in synchronization with the feeding operation of the chain mold 14 of the molding apparatus 3. By rotating the upper and lower common drive gears 25 in the directions of arrows B and B ′, the front and rear drive gears 24 and drive pulleys 22 of the upper belt drive units 18 and 19 are driven to rotate counterclockwise as indicated by arrow C. In addition, the drive gear 24 and the drive pulley 22 before and after the lower belt drive units 18 ′ and 19 ′ are driven to rotate clockwise as indicated by an arrow C ′.

それによって、上側の各ベルト駆動部18,19の駆動ベルト23が矢印Dの如く反時計回りに回転駆動され、且つ下側の各ベルト駆動部18’,19’の駆動ベルト23が矢印D’の如く時計回りに回転駆動されて、部分成形コルゲートチューブ6を引き取って矢印Eの如く前方に送り出す。   As a result, the drive belts 23 of the upper belt drive units 18 and 19 are rotationally driven counterclockwise as indicated by the arrow D, and the drive belts 23 of the lower belt drive units 18 ′ and 19 ′ are driven by the arrow D ′. As shown in the figure, the partially molded corrugated tube 6 is taken out and fed forward as indicated by an arrow E.

さらに、前後上下の各ベルト駆動部18〜19’は、スプリング又はエアシリンダ等といった不図示の付勢手段(付勢部材)で、矢印F,F’の如く、前後一対のガイドプーリ20,21のうちの前側のガイドプーリ20を後側のガイドプーリ21よりも部分成形コルゲートチューブ6の中心軸線6aに向けて押し付ける方向に、揺動(回動ないし傾動)可能となっている。上側の各ベルト駆動部18,19の前側のガイドプーリ20は付勢手段で矢印Fの如く時計回りに押圧付勢され、下側の各ベルト駆動部18’,19’の前側のガイドプーリ20は付勢手段で矢印F’の如く反時計回りに押圧付勢される。   Further, the front and rear and upper and lower belt drive units 18 to 19 'are biasing means (biasing members) (not shown) such as springs or air cylinders, and a pair of front and rear guide pulleys 20, 21 as indicated by arrows F and F'. Among them, the front guide pulley 20 can be swung (turned or tilted) in a direction in which the front guide pulley 20 is pressed toward the central axis 6 a of the partially molded corrugated tube 6 rather than the rear guide pulley 21. The guide pulley 20 on the front side of the upper belt drive units 18 and 19 is urged clockwise by the urging means as indicated by the arrow F, and the guide pulley 20 on the front side of the lower belt drive units 18 ′ and 19 ′. Is biased counterclockwise as indicated by arrow F 'by the biasing means.

なお、明細書で「前側」とは、部分成形コルゲートチューブ6の送り方向(矢印E方向)の先頭側であり、「後側」とは、部分成形コルゲートチューブ6の先頭側に続く後続部分側である。あるいは、部分成形コルゲートチューブ6に対する上下のベルト駆動部19,19’の入口26側が「後側」であり、出口27側が「前側」である。   In the specification, “front side” refers to the leading side in the feeding direction (arrow E direction) of the partially molded corrugated tube 6, and “rear side” refers to the succeeding partial side following the leading side of the partially molded corrugated tube 6. It is. Alternatively, the inlet 26 side of the upper and lower belt drive units 19, 19 ′ with respect to the partially molded corrugated tube 6 is the “rear side”, and the outlet 27 side is the “front side”.

各ベルト駆動部18〜19’の詳細構造の一例を以下に記述する。例えば、前後一対のガイドプーリ20,21の水平な各中心軸(図示せず)が、装置本体15(図1)の左右の各側壁17(図1)に設けた不図示の円弧状の長孔(軸受孔)に径方向揺動(回動ないし傾動)自在に支持され、上側又は下側の駆動プーリ22の水平な中心軸(図示せず)は、装置本体15の左右の各側壁17に設けた円孔(図示せず)にベアリングを介して径方向不動に支持されている。   An example of the detailed structure of each belt drive unit 18-19 'will be described below. For example, each horizontal center axis (not shown) of the pair of front and rear guide pulleys 20 and 21 has an arc-like length (not shown) provided on the left and right side walls 17 (FIG. 1) of the apparatus main body 15 (FIG. 1). A horizontal center axis (not shown) of the upper or lower drive pulley 22 is supported by a hole (bearing hole) so as to freely swing in the radial direction (rotation or tilting). It is supported in a radial direction through a bearing in a circular hole (not shown) provided in.

前後一対のガイドプーリ20,21が駆動プーリ22の中心軸を支点として、側壁17の長孔の長さの範囲で前後方向に一体的に揺動(回動)自在となっている。各ガイドプーリ20,21は中心軸にベアリングを介して回転自在となっており、中心軸は回転しない。各ガイドプーリ20,21の中心軸はプーリ径方向の連結部材(図示せず)で一体的に連結されており、前後のガイドプーリ20,21は矢印F,F’方向に一体的に揺動する。   A pair of front and rear guide pulleys 20 and 21 are swingable (rotatable) integrally in the front-rear direction within the range of the length of the long hole of the side wall 17 with the central axis of the drive pulley 22 as a fulcrum. The guide pulleys 20 and 21 are rotatable about the central axis via a bearing, and the central axis does not rotate. The central axes of the guide pulleys 20 and 21 are integrally connected by a pulley radial connecting member (not shown), and the front and rear guide pulleys 20 and 21 swing integrally in the directions of arrows F and F ′. To do.

そして、前後一対のガイドプーリ20,21のうちの前側のガイドプーリ20の中心軸が、垂直方向ないしそれに近い縦方向の圧縮コイルスプリング又はエアシリンダ等といった付勢手段(図示せず)で部分成形コルゲートチューブ6の中心軸線6aに向けて付勢されている。なお、付勢手段として、板ばねや、共通の引張コイルばね(共通の引張コイルばねは上下のベルト駆動部19,19’の前側の各ガイドローラ20の中心軸を相互に連結して接近する方向に付勢する)や、ゴム材等といった弾性部材を用いることも可能である。   The central axis of the front guide pulley 20 of the pair of front and rear guide pulleys 20 and 21 is partially molded by an urging means (not shown) such as a compression coil spring or an air cylinder in the vertical direction or a vertical direction close thereto. The corrugated tube 6 is biased toward the central axis 6a. As a biasing means, a leaf spring or a common tension coil spring (a common tension coil spring is connected to each other by connecting the central axes of the front guide rollers 20 of the upper and lower belt drive units 19 and 19 'to each other. It is also possible to use an elastic member such as a rubber material.

図2の部分成形コルゲートチューブ6の引取動作に伴って、後側の上下一対のベルト駆動部19,19’が、部分成形コルゲートチューブ6の前側の大径な蛇腹管部8から後側の小径なストレート管部7に相対的に移行した際に、付勢手段(図示せず)によって後側の上下一対のベルト駆動部19,19’が矢印F,F’の如く、上下の前側のガイドプーリ20を近づける方向に回動する(上側のベルト駆動部19は時計回りに回動し、下側のベルト駆動部19’は反時計回りに回動する)。   With the take-up operation of the partially molded corrugated tube 6 shown in FIG. 2, the pair of upper and lower belt drive units 19 and 19 ′ are moved from the large diameter bellows tube portion 8 on the front side of the partially molded corrugated tube 6 to the small diameter on the rear side. When moving relatively to the straight pipe portion 7, the pair of upper and lower belt drive portions 19 and 19 'on the rear side are urged by means of biasing means (not shown) as indicated by the arrows F and F'. The pulley 20 is rotated in the direction in which the pulley 20 approaches (the upper belt drive unit 19 rotates clockwise, and the lower belt drive unit 19 ′ rotates counterclockwise).

これにより、前側の上下のガイドプーリ20が後側の上下のガイドプーリ21よりも部分成形コルゲートチューブ6の外面に近接し、後側の上下のガイドプーリ21は部分成形コルゲートチューブ6の径方向に離間し、前側のガイドプーリ20に沿う駆動ベルト部分23aが部分成形コルゲートチューブ6の小径なストレート管部7の外面に付勢手段の付勢力で押し付けられる。これにより、小径なストレート管部7が上下のベルト駆動部19,19’で確実に引き取られて前方に送り出される。   Thereby, the front upper and lower guide pulleys 20 are closer to the outer surface of the partially molded corrugated tube 6 than the rear upper and lower guide pulleys 21, and the rear upper and lower guide pulleys 21 are arranged in the radial direction of the partially molded corrugated tube 6. The drive belt portion 23 a that is spaced apart and along the front guide pulley 20 is pressed against the outer surface of the small-diameter straight tube portion 7 of the partially molded corrugated tube 6 by the urging force of the urging means. Thereby, the small-diameter straight tube portion 7 is reliably taken up by the upper and lower belt drive portions 19 and 19 ′ and sent forward.

このように、部分成形コルゲートチューブ6の外径の変化(大径から小径への変化)に応じて、駆動ベルト23が部分成形コルゲートチューブ6の小径なストレート管部7を確実に引き取ることができる。   Thus, according to the change in the outer diameter of the partially molded corrugated tube 6 (change from the large diameter to the small diameter), the drive belt 23 can reliably take up the small straight pipe portion 7 of the partially molded corrugated tube 6. .

また、図2において、部分成形コルゲートチューブ6の小径なストレート管部7の引き取り時に、後側の上下一対のベルト駆動部19,19’の後側の各ガイドプーリ21が前側の各ガイドプーリ20よりも部分成形コルゲートチューブ6の径方向外側に離間して、部分成形コルゲートチューブ6の外面に面する略水平な駆動ベルト部分(前後一対のガイドプーリ20,21の間の駆動ベルト部分)23bが、後方の入口26側を開いたように、テーパ状に傾斜するので(入口がストレート管部7よりも幅広な開口26となるので)、部分成形コルゲートチューブ6の次の大径な蛇腹管部8がテーパ状の入口(開口)26から上下の駆動ベルト23の間に引っ掛かり等なくスムーズに挿入されて、蛇腹管部8の引き込み動作がスムーズ且つ確実に行われる。   In FIG. 2, when the small-diameter straight tube portion 7 of the partially molded corrugated tube 6 is taken up, the rear guide pulleys 21 on the rear side of the pair of upper and lower belt drive portions 19, 19 ′ are replaced with the front guide pulleys 20. A substantially horizontal driving belt portion (a driving belt portion between a pair of front and rear guide pulleys 20 and 21) 23b that is spaced further outward in the radial direction of the partially molded corrugated tube 6 and faces the outer surface of the partially molded corrugated tube 6. As the rear inlet 26 side is opened, it is inclined in a tapered shape (because the inlet becomes an opening 26 wider than the straight pipe portion 7), so that the next large-diameter bellows pipe portion of the partially molded corrugated tube 6 is provided. 8 is smoothly inserted from the tapered inlet (opening) 26 between the upper and lower drive belts 23 without being caught, and the retracting operation of the bellows tube portion 8 is smooth and reliable. It is carried out.

図2において、前側の上下一対のベルト駆動部18,18’の各駆動ベルト23は部分成形コルゲートチューブ6の大径な蛇腹管部8の外面に押接しており、前後一対のガイドプーリ20,21の間の駆動ベルト部分23bは平行(水平)に位置している。   In FIG. 2, each drive belt 23 of the pair of upper and lower belt drive portions 18, 18 ′ on the front side is pressed against the outer surface of the large-diameter bellows tube portion 8 of the partially molded corrugated tube 6, and a pair of front and rear guide pulleys 20, The drive belt portion 23b between 21 is positioned in parallel (horizontal).

前側の上下のベルト駆動部18,18’においても後側のベルト駆動部19,19’と同様に、前側のガイドプーリ20が不図示の付勢手段で部分成形コルゲートチューブ6の中心軸線6aに向けて付勢され、各ガイドプーリ20,21は装置本体15(図1)の側壁17の不図示の円弧状の長孔に沿って揺動自在となっているが、大径な蛇腹管部8に押接した状態では、前後一対のガイドプーリ20,21は揺動せずに同じ高さで位置している。   Also in the front upper and lower belt drive portions 18 and 18 ', the front guide pulley 20 is moved to the central axis 6a of the partially formed corrugated tube 6 by a biasing means (not shown) in the same manner as the rear belt drive portions 19 and 19'. The guide pulleys 20 and 21 are oscillated along the arcuate elongated holes (not shown) of the side wall 17 of the apparatus main body 15 (FIG. 1). In the state of being pressed against 8, the pair of front and rear guide pulleys 20 and 21 are positioned at the same height without swinging.

図2において、後側のベルト駆動部19,19’の前側のガイドプーリ20は前側のベルト駆動部18,18’の各ガイドプーリ20,21よりも部分成形コルゲートチューブ6の中心軸線6aに向けて移動している。   In FIG. 2, the front guide pulley 20 of the rear belt drive portions 19 and 19 ′ is directed toward the central axis 6 a of the partially molded corrugated tube 6 rather than the guide pulleys 20 and 21 of the front belt drive portions 18 and 18 ′. Is moving.

なお、図2において、部分成形コルゲートチューブ6のストレート管部7の周方向に形成された低い凸条(蛇腹管部8の外径よりも小径な凸条)7aは、例えばストレート管部7の曲げ剛性を高めるためのものであり、省略することも可能である。また、図1,図2において、鎖線で示す符号28の部分は、例えば、部分成形コルゲートチューブ6の径方向の位置規制を行うためのリング部材である。   In FIG. 2, a low protrusion (a protrusion having a diameter smaller than the outer diameter of the bellows tube portion 8) 7 a formed in the circumferential direction of the straight tube portion 7 of the partially molded corrugated tube 6 is, for example, the straight tube portion 7. This is for increasing the bending rigidity and can be omitted. 1 and 2, a portion indicated by a reference numeral 28 indicated by a chain line is, for example, a ring member for restricting the position of the partially molded corrugated tube 6 in the radial direction.

図2の後側の上下一対のベルト駆動部19,19’のように、部分成形コルゲートチューブ6の小径なストレート管部7を引き取る際に、ベルト駆動部19,19’が矢印F,F’方向に揺動して、前側のガイドローラ20に沿う駆動ベルト部分23aのみで小径なストレート管部7を引き取ることで、例えば部分成形コルゲートチューブ6に対する上下の駆動ベルト23の摩擦抵抗が減少して、駆動ベルト23の回転速度が、蛇腹管部6を引き取る際の速度に比べて若干増減して、若干の速度差を生じる懸念があるが、例えば、上下の駆動プーリ22内にワンウェイクラッチ(図示せず)を設けておくことで、この懸念を解消することができる。   When pulling out the small straight tube portion 7 of the partially molded corrugated tube 6 like the pair of upper and lower belt drive portions 19 and 19 ′ on the rear side of FIG. 2, the belt drive portions 19 and 19 ′ are moved to the arrows F and F ′. The frictional resistance of the upper and lower drive belts 23 with respect to the partially formed corrugated tube 6 is reduced, for example, by pulling the straight tube portion 7 having a small diameter only by the drive belt portion 23a along the guide roller 20 on the front side. There is a concern that the rotational speed of the drive belt 23 slightly increases or decreases compared with the speed at which the bellows tube portion 6 is pulled, and a slight speed difference may occur. For example, a one-way clutch (see FIG. (Not shown) can be used to resolve this concern.

ワンウェイクラッチは既存のもので(スプラグ式やカム式のものが挙げられる)、駆動プーリ22の中心軸(中心軸は駆動ギア24に固定されている)と駆動プーリ22の外周壁との間に配置され、中心軸の駆動回転に対して駆動プーリ22を矢印C,C’方向すなわち駆動方向にのみロックして回転可能とし、駆動方向とは反対の方向には遊動回転自在(フリー)とすることで、駆動ギア24と駆動プーリ22(駆動ベルト23)との速度差、すなわち部分成形コルゲートチューブ6の大径な蛇腹管部8と小径なストレート管部7とに対する駆動ベルト23の速度差を吸収させて、部分成形コルゲートチューブ6の引取動作をスムーズに行わせることができる。   The one-way clutch is an existing one (including a sprag type and a cam type), and is between the central axis of the drive pulley 22 (the central axis is fixed to the drive gear 24) and the outer peripheral wall of the drive pulley 22. The driving pulley 22 is arranged to be locked only in the directions of arrows C and C ′, that is, in the driving direction and can be rotated with respect to the driving rotation of the central axis, and is freely rotatable in the direction opposite to the driving direction (free). Thus, the speed difference between the drive gear 24 and the drive pulley 22 (drive belt 23), that is, the speed difference of the drive belt 23 with respect to the large-diameter bellows tube portion 8 and the small-diameter straight tube portion 7 of the partially formed corrugated tube 6 is obtained. It can be absorbed and the take-up operation of the partially molded corrugated tube 6 can be performed smoothly.

上記した図1〜図2の実施形態によれば、引取装置5において、部分成形コルゲートチューブ6を挟む上下の駆動ベルト23を前後一対配置したことで、外径の多少異なる部分成形コルゲートチューブ6を常にスムーズ且つ確実に引き取ることができる。   According to the above-described embodiment shown in FIGS. 1 to 2, in the take-up device 5, the pair of upper and lower drive belts 23 sandwiching the partially formed corrugated tube 6 are disposed in the front and rear, so that the partially formed corrugated tube 6 having a slightly different outer diameter is provided. It can always be picked up smoothly and reliably.

また、引取装置5において、駆動ベルト23の駆動にサーボモータ(図示せず)を使用し、成形装置3の速度に同期した部分成形コルゲートチューブ6の引き取りを行うことで、成形装置3の速度よりも遅い引き取り速度で発生する部分成形コルゲートチューブ6の変形・反り、及び成形装置3の速度よりも早い引き取り速度で発生する部分成形コルゲートチューブ6の伸び(部分成形コルゲートチューブ6の肉厚の減少、長さの増加)を抑制することができる。   Further, in the take-up device 5, a servomotor (not shown) is used to drive the drive belt 23, and the partially formed corrugated tube 6 is taken up in synchronization with the speed of the forming device 3. Deformation and warping of the partially molded corrugated tube 6 that occurs at a lower take-off speed, and elongation of the partially formed corrugated tube 6 that occurs at a take-up speed faster than the speed of the forming apparatus 3 (reduction in the thickness of the partially formed corrugated tube 6; Increase in length) can be suppressed.

なお、上記実施形態においては、一対のガイドプーリ20,21と一つの駆動プーリ22との計三つのプーリ20〜22を用いて各ベルト駆動部18〜19’を構成したが、例えば一つのガイドプーリ20(又は21)と一つの駆動プーリ22との前後計二つのプーリ20(又は21),22を用いてベルト駆動部(図示せず)を構成することも可能である。   In the above embodiment, each belt drive unit 18-19 ′ is configured by using a total of three pulleys 20-22 including a pair of guide pulleys 20, 21 and one drive pulley 22. However, for example, one guide pulley is used. A belt drive unit (not shown) can be configured by using two pulleys 20 (or 21) and 22 in total including a pulley 20 (or 21) and a single drive pulley 22.

この場合、前後のプーリ20(又は21),22に駆動ベルト(23)が掛け渡され、前又は後の駆動プーリ22の中心軸に駆動ギア24が固定され、駆動ギア24が例えば共通駆動ギア25で駆動される。前側のベルト駆動部18,18’の駆動プーリ22は後側に配置され、後側のベルト駆動部19,19’の駆動プーリ22は前側に配置されることが、共通駆動ギア25を使用する上で好ましい。駆動ベルト(23)はその上側部分と下側部分とが平行に掛け渡される。   In this case, the drive belt (23) is stretched over the front and rear pulleys 20 (or 21) and 22, the drive gear 24 is fixed to the central axis of the front or rear drive pulley 22, and the drive gear 24 is, for example, a common drive gear. 25. The drive pulley 22 of the front belt drive units 18 and 18 'is disposed on the rear side, and the drive pulley 22 of the rear belt drive units 19 and 19' is disposed on the front side, using the common drive gear 25. Preferred above. The drive belt (23) has its upper portion and lower portion stretched in parallel.

そして、各ベルト駆動部の前側のプーリ22が付勢手段(図示せず)で部分成形コルゲートチューブ6の中心軸線6aに向けて付勢され、部分成形コルゲートチューブ6の小径なストレート管部7に押接する際に、後側のプーリ21が部分成形コルゲートチューブ6の中心軸線6aから径方向外側に離間して広い入口部26を構成する。なお、共通駆動ギア25に代えて共通駆動ベルト(図示せず)を用い、共通駆動ベルトを一つの駆動ギア(図示せず)で駆動することも可能である。これは図2の三つのプーリ20〜22を用いた実施形態においても同様に適用可能である。   Then, the pulley 22 on the front side of each belt drive unit is urged toward the central axis 6a of the partially molded corrugated tube 6 by an urging means (not shown), and the small-diameter straight tube portion 7 of the partially molded corrugated tube 6 is urged. At the time of pressing, the rear pulley 21 is spaced radially outward from the central axis 6 a of the partially molded corrugated tube 6 to form a wide inlet portion 26. It is also possible to use a common drive belt (not shown) instead of the common drive gear 25 and drive the common drive belt with one drive gear (not shown). This can be similarly applied to the embodiment using the three pulleys 20 to 22 in FIG.

また、図2の実施形態においては、各ベルト駆動部18〜19’の前側のプーリ20を付勢手段で部分成形コルゲートチューブ6の中心軸線6aに向けて付勢した例で説明したが、例えば、後側のプーリ21を付勢手段で部分成形コルゲートチューブ6の中心軸線6aから外側に離間する方向に付勢することで、後側のプーリ21と連結された前側のプーリ20を部分成形コルゲートチューブ6の小径なストレート管部6に押接させることも可能である。   In the embodiment of FIG. 2, the example has been described in which the front pulley 20 of each belt drive unit 18 to 19 ′ is urged toward the central axis 6 a of the partially molded corrugated tube 6 by the urging means. The rear pulley 21 is biased by the biasing means in a direction away from the central axis 6a of the partially molded corrugated tube 6 so that the front pulley 20 connected to the rear pulley 21 is partially molded corrugated. It is also possible to press the tube 6 against the small diameter straight pipe portion 6.

あるいは、各プーリ20〜22の中心軸をブラケット(図示せず)で支持させ、ブラケットを装置本体15の左右の側板部17(図1)に対して付勢手段で図2の矢印F,F’方向(前側のプーリ20が部分成形コルゲートチューブ6の中心軸線6aに向けて移動する方向)に付勢することも可能である。   Alternatively, the central axes of the pulleys 20 to 22 are supported by brackets (not shown), and the brackets are urged against the left and right side plate portions 17 (FIG. 1) of the apparatus main body 15 by arrows F and F in FIG. It is also possible to bias in the 'direction (the direction in which the front pulley 20 moves toward the central axis 6a of the partially molded corrugated tube 6).

また、各ベルト駆動部18〜19’の後側のプーリ21を付勢手段で部分成形コルゲートチューブ6の中心軸線6aに向けて付勢したり、前側のプーリ20を付勢手段で部分成形コルゲートチューブ6の中心軸線6aから離間する方向に付勢することも可能である。但しこの場合は、部分成形コルゲートチューブ6の小径なストレート部7を、後側のプーリ21に沿う駆動ベルト部分23cで前方に送出することはできるが、上下のベルト駆動部19,19’の後部の入口26が上下に広がらないので、部分成形コルゲートチューブ6の次の大径な蛇腹管部8の前端が入口26に衝接する懸念はある。   Further, the rear pulley 21 of each belt drive unit 18 to 19 ′ is biased by the biasing means toward the central axis 6a of the partially molded corrugated tube 6, or the front pulley 20 is partially biased by the biasing means. It is also possible to urge the tube 6 in a direction away from the central axis 6a. However, in this case, the small-diameter straight portion 7 of the partially molded corrugated tube 6 can be sent forward by the drive belt portion 23c along the rear pulley 21, but the rear portions of the upper and lower belt drive portions 19, 19 ′. Therefore, there is a concern that the front end of the next large-diameter bellows tube portion 8 of the partially molded corrugated tube 6 may come into contact with the inlet 26.

また、図1の実施形態においては、上下各一対のベルト駆動部18〜19’を部分成形コルゲートチューブ6の長手方向の前後に一対配置したが、例えば左右各一対のベルト駆動部18〜19’を部分成形コルゲートチューブ6の長手方向の前後に一対配置することも可能である。この場合は、部分成形コルゲートチューブ6が下向きに撓まないように、部分成形コルゲートチューブ6を下側の水平な帯状のガイド板等(図示せず)で支持する必要がある。   Further, in the embodiment of FIG. 1, a pair of upper and lower belt drive units 18 to 19 ′ are arranged in front and rear in the longitudinal direction of the partially formed corrugated tube 6.
