Description
この発明は、紙、フィルムなどのウェブを巻き取る巻取装置の巻取支持軸に関し、特に紙管等の巻取芯を要しない、コアレスでウェブを巻取る巻取装置のウェブ巻取支持軸に関する。 The present invention relates to a winding support shaft of a winding device for winding a web such as paper or film, and in particular, does not require a winding core such as a paper tube, and the web winding support shaft of a winding device for winding a web without a core. About.
紙、フィルムなどのウェブロールをスリット工程において所定幅で切断する際、ウェブロールの両端縁が耳端となる。従来、この耳端は、紙管等の芯に巻取った後、改めて芯と耳端とを分別して処理されていた。 When a web roll such as paper or film is cut at a predetermined width in the slitting process, both end edges of the web roll become ear edges. Conventionally, after the end of the ear is wound around a core such as a paper tube, the core and the end of the ear are separated and processed again.
昨今、耳端リサイクルの簡素化や紙管等の芯のコストの削減が望まれており、従来から芯を要しないコアレスでウェブを巻取る装置や方法が提案されている。 In recent years, it has been desired to simplify ear-end recycling and to reduce the cost of cores such as paper tubes, and conventionally, a coreless apparatus and method for winding a web without cores have been proposed.
しかし、一度巻取った耳端を再度コアとウェブ素材とに分別するのは労力を要する作業である。また、耳端を巻取ったロールには巻取芯になっている薄い紙管が潰れる程の、巻取りによる大きな力が作用している。この力をどのように支えるかが課題となっている。 However, separating the ear ends once wound up into the core and the web material is a labor-intensive operation. In addition, a large force due to winding is applied to the roll wound around the ear end so that the thin paper tube serving as the winding core is crushed. The challenge is how to support this force.
さらに、ウェブ素材がゴムのように伸びやすい物の場合、コアレスで巻取るには、巻取芯の円周長さの大きな変化を必要とすることも課題となっている。 Furthermore, when the web material is an easily stretchable material such as rubber, it is also a problem that a large change in the circumferential length of the winding core is required in order to wind the core material.
本発明は、コアレスで、紙、フィルムなどのウェブを巻取る際に、使用されているウェブ巻取支持軸に対して作用する巻き締まりの大きな力を支えることができ、ウェブを巻取る際の大きな円周長さと、ウェブの巻き取りが完了し、使用していたウェブ巻取支持軸を引き抜く際の小さな円周長さとの間で円周長さを大きく変化させることが可能なウェブ巻取支持軸を提供することを目的にしている。 The present invention is coreless and can support a large tightening force acting on a web winding support shaft that is used when winding a web such as paper or film. Web winding that can greatly change the circumferential length between the large circumferential length and the small circumferential length when the web winding support shaft is pulled out after the web winding is completed The purpose is to provide a support shaft.
本発明は、回転軸と共に回転する支持筒の外周に、前記支持筒の周方向に所定の間隔を空けて基端が旋回可能に支持されている複数枚の支持板を配備し、前記回転軸に対して前記支持筒の軸方向外側から着脱可能で、前記回転軸の周方向に回動可能な制御盤を、前記回転軸の周方向に回動させることによって、前記複数枚の支持板をそれぞれ前記基端を中心として旋回させ、前記複数枚の支持板の先端によって形成される周の径の大きさを変更できるようにして前記課題を解決したのである。 According to the present invention, a plurality of support plates are provided on the outer periphery of a support cylinder that rotates together with the rotation shaft, with a base end pivotably supported at a predetermined interval in the circumferential direction of the support tube, and the rotation shaft The control board, which is detachable from the outside in the axial direction of the support cylinder and is rotatable in the circumferential direction of the rotating shaft, is rotated in the circumferential direction of the rotating shaft, whereby the plurality of support plates are Each of the above-mentioned problems is solved by turning around the base end and changing the diameter of the circumference formed by the tips of the plurality of support plates.

支持板６は、制御盤３が回転軸２１に装着される側の側壁にそれぞれ支持板６の基端側から対向する先端側に向かって伸びる溝条７ａ、７ｂ、７ｃ、７ｄ、７ｅ、７ｆ、７ｇ、７ｈ（本明細書、図面において総称して「溝条７」と表すことがある）を備えている。 The support plate 6 has grooves 7a, 7b, 7c, 7d, 7e, 7f extending from the base end side of the support plate 6 toward the front end side facing the side wall on the side where the control panel 3 is mounted on the rotary shaft 21, respectively. , 7g, 7h (may be collectively referred to as “groove 7” in the present specification and drawings).
制御盤３は、回転軸２１の回転中心Ｏを中心とする所定の径を有する円周上に、周方向に所定の間隔を空けて配備されていて、支持筒１の方向に向かって伸び、制御盤３が回転軸２１に装着された際に支持板６が側壁に備えている溝条７に挿入される支持棒４ａ、４ｂ、４ｃ、４ｄ、４ｅ、４ｆ、４ｇ、４ｈ（本明細書、図面において総称して「支持棒４」と表すことがある）を備えている。 The control panel 3 is arranged on the circumference having a predetermined diameter centered on the rotation center O of the rotary shaft 21 with a predetermined interval in the circumferential direction, and extends toward the support cylinder 1. Support bars 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h (this specification) which are inserted into the groove 7 provided on the side wall of the support plate 6 when the control panel 3 is mounted on the rotating shaft 21 , And may be collectively referred to as “support bar 4” in the drawings).
すなわち、制御盤３が回転軸２１に装着されると、制御盤３が備えている支持棒４ａ、４ｂ、４ｃ、４ｄ、４ｅ、４ｆ、４ｇ、４ｈが、それぞれ対応する支持板６ａ、６ｂ、６ｃ、６ｄ、６ｅ、６ｆ、６ｇ、６ｈの溝条７ａ、７ｂ、７ｃ、７ｄ、７ｅ、７ｆ、７ｇ、７ｈ内に挿入される（図４（ａ）、（ｂ））。 That is, when the control panel 3 is mounted on the rotary shaft 21, the support bars 4a, 4b, 4c, 4d, 4e, 4f, 4g, and 4h provided in the control panel 3 are respectively supported by the corresponding support plates 6a, 6b, 6c, 6d, 6e, 6f, 6g and 6h are inserted into the grooves 7a, 7b, 7c, 7d, 7e, 7f, 7g and 7h (FIGS. 4A and 4B).

As shown in FIG. 4A, the support bar 4 has a groove when the support plate 6 is supported by the support cylinder 1 so as to extend in the radial direction of the support cylinder 1 from the proximal end side toward the distal end side. It is inserted into the base end side of the support plate 6 of the strip 7.
次に、本発明のウェブ巻取支持軸２０の使用方法を説明する。 Next, the usage method of the web winding support shaft 20 of this invention is demonstrated.
図４（ａ）図示のように、支持板６が基端側から先端側に向かって支持筒１の径方向に伸びるように支持筒１に支持されている状態では、回転軸２１に対して支持筒１の軸方向外側から装着される制御盤３の支持棒４ａ、４ｂ、４ｃ、４ｄ、４ｅ、４ｆ、４ｇ、４ｈは、それぞれ対応する支持板６ａ、６ｂ、６ｃ、６ｄ、６ｅ、６ｆ、６ｇ、６ｈの溝条７ａ、７ｂ、７ｃ、７ｄ、７ｅ、７ｆ、７ｇ、７ｈの、支持板６の基端側に挿入されている。 As shown in FIG. 4A, in the state where the support plate 6 is supported by the support cylinder 1 so as to extend in the radial direction of the support cylinder 1 from the proximal end side toward the distal end side, The support rods 4a, 4b, 4c, 4d, 4e, 4f, 4g, and 4h of the control panel 3 mounted from the outside in the axial direction of the support cylinder 1 respectively correspond to the corresponding support plates 6a, 6b, 6c, 6d, 6e, and 6f. , 6g, 6h are inserted into the base end side of the support plate 6 of the grooves 7a, 7b, 7c, 7d, 7e, 7f, 7g, 7h.
この状態で、不図示のピンなどによって制御盤３を回転軸２１あるいは支持筒１に固定し、図１、図４（ａ）図示のように、支持板６が基端側から先端側に向かって支持筒１の径方向に伸びるように支持筒１に支持される状態を維持しつつ、回転軸２１を矢印８方向に回転させる。これにより、支持板６ａ、６ｂ、６ｃ、６ｄ、６ｅ、６ｆ、６ｇ、６ｈの先端側で形成される周を内径として、紙、ウェブ等のフィルムを巻き取ることができる。 In this state, the control panel 3 is fixed to the rotary shaft 21 or the support cylinder 1 with a pin (not shown), and the support plate 6 is directed from the base end side to the tip end side as shown in FIGS. The rotating shaft 21 is rotated in the direction of the arrow 8 while maintaining the state supported by the supporting cylinder 1 so as to extend in the radial direction of the supporting cylinder 1. As a result, a film such as paper or web can be wound with the circumference formed on the tip side of the support plates 6a, 6b, 6c, 6d, 6e, 6f, 6g, 6h as the inner diameter.
巻き取りを行っている際、各支持板６には巻き取りによる大きな力（時には数トンになることもある）が作用する。しかし、図４（ａ）図示のように各支持板６は縦に使用されているので、板厚を薄くしても、この力を支持することができる。また、各支持板６に作用する力は、図４（ａ）図示のように垂直方向に軸芯に伝達され、更に、例えば、支持板６ａに作用している力が軸芯に伝達される一方で、回転軸２１の回転中心Ｏを中心として支持板６ａの点対称となる位置で支持筒１の外周壁に支持されている側の支持板６ｅに作用している力も軸芯に伝達され、力の方向が互いに逆向きになる。この結果、巻き締まりによって生じる数トンの力は軸芯において互いに相殺され、支持板６に要求される強度は小さくてすむ。この結果、支持板６の軽量化を図ることが可能になる。 During winding, a large force (sometimes several tons) due to winding acts on each support plate 6. However, since each support plate 6 is used vertically as shown in FIG. 4A, this force can be supported even if the plate thickness is reduced. Further, the force acting on each support plate 6 is transmitted to the shaft core in the vertical direction as shown in FIG. 4A, and further, for example, the force acting on the support plate 6a is transmitted to the shaft core. On the other hand, the force acting on the support plate 6e on the side supported by the outer peripheral wall of the support cylinder 1 at a position where the support plate 6a is point-symmetric about the rotation center O of the rotation shaft 21 is also transmitted to the shaft core. , The direction of force is opposite to each other. As a result, the force of several tons caused by the tightening is canceled out at the shaft core, and the strength required for the support plate 6 is small. As a result, the support plate 6 can be reduced in weight.
巻き取り完了後、不図示のピンによる制御盤３の回転軸２１あるいは支持筒１への固定を解除し、制御盤３を回転軸２１の周囲で、矢印１０方向に回転させる。これにより、制御盤３に配備されている支持棒４ａ、４ｂ、４ｃ、４ｄ、４ｅ、４ｆ、４ｇ、４ｈも、図１、図３（ａ）、図４（ａ）図示の状態から、回転軸２１の周囲で、矢印１０方向に回転し、それぞれ、図２、図３（ｂ）、図４（ｂ）図示の状態となる。 After the winding is completed, the fixing of the control panel 3 to the rotating shaft 21 or the support cylinder 1 by a pin (not shown) is released, and the control panel 3 is rotated around the rotating shaft 21 in the direction of the arrow 10. As a result, the support rods 4a, 4b, 4c, 4d, 4e, 4f, 4g, and 4h arranged in the control panel 3 are also rotated from the states shown in FIGS. 1, 3 (a), and 4 (a). It rotates in the direction of the arrow 10 around the shaft 21 to be in the state shown in FIG. 2, FIG. 3 (b), and FIG. 4 (b), respectively.
支持棒４ａ、４ｂ、４ｃ、４ｄ、４ｅ、４ｆ、４ｇ、４ｈは、対応する支持板６ａ、６ｂ、６ｃ、６ｄ、６ｅ、６ｆ、６ｇ、６ｈの溝条７ａ、７ｂ、７ｃ、７ｄ、７ｅ、７ｆ、７ｇ、７ｈ内に挿入されている状態で、図１、図３（ａ）、図４（ａ）図示の状態から図２、図３（ｂ）、図４（ｂ）図示の状態へと移動する。そこで、支持棒４は、それぞれ、溝条７内を摺動し、支持板６ａ、６ｂ、６ｃ、６ｄ、６ｅ、６ｆ、６ｇ、６ｈは、基端側の旋回穴５ａ、５ｂ、５ｃ、５ｄ、５ｅ、５ｆ、５ｇ、５ｈを支持している支持突起２ａ、２ｂ、２ｃ、２ｄ、２ｅ、２ｆ、２ｇ、２ｈの周囲に、矢印１１ａ、１１ｂ、１１ｃ、・・・・、１１ｈで示すように旋回する（図２、図４（ｂ））。 The support rods 4a, 4b, 4c, 4d, 4e, 4f, 4g, and 4h are the grooves 7a, 7b, 7c, 7d, and 7e of the corresponding support plates 6a, 6b, 6c, 6d, 6e, 6f, 6g, and 6h. 7f, 7g and 7h, the state shown in FIG. 1, FIG. 3 (a) and FIG. 4 (a) to the state shown in FIG. 2, FIG. 3 (b) and FIG. 4 (b). Move to. Therefore, the support rod 4 slides in the groove 7, and the support plates 6a, 6b, 6c, 6d, 6e, 6f, 6g, 6h are the pivot holes 5a, 5b, 5c, 5d on the base end side. As shown by arrows 11a, 11b, 11c,..., 11h around the support protrusions 2a, 2b, 2c, 2d, 2e, 2f, 2g, and 2h that support 5e, 5f, 5g, and 5h. (Figs. 2 and 4 (b)).
この結果、支持板６ａ、６ｂ、６ｃ、６ｄ、６ｅ、６ｆ、６ｇ、６ｈの先端側で形成される周の径は図１、図４（ａ）にＲ１で示す状態から、図２、図４（ｂ）にＲ２で示す状態へと小さくなる。 As a result, the diameter of the circumference formed on the front end side of the support plates 6a, 6b, 6c, 6d, 6e, 6f, 6g, 6h is changed from the state indicated by R1 in FIG. 1 and FIG. 4 (b) decreases to the state indicated by R2.
こうして、図１、図４（ａ）に示す、ウェブを巻取る際の直径Ｒ１に対応する大きな円周長さから、図２、図４（ｂ）に示す、ウェブの巻き取りが完了し、使用していたウェブ巻取支持軸を引き抜く際の直径Ｒ２に対応する小さな円周長さへと、円周長さを大きく縮小させることができる。しかも、ウェブの巻き取り完了後、制御盤３を回転軸２１の周囲で、矢印１０方向に回転させるだけで、簡単に径（周方向の長さ）を小さくすることができる。 Thus, from the large circumferential length corresponding to the diameter R1 when winding the web shown in FIGS. 1 and 4 (a), the winding of the web shown in FIGS. 2 and 4 (b) is completed, The circumferential length can be greatly reduced to a small circumferential length corresponding to the diameter R2 when the web winding support shaft that has been used is pulled out. Moreover, the diameter (the length in the circumferential direction) can be easily reduced by simply rotating the control panel 3 around the rotary shaft 21 in the direction of the arrow 10 after the web winding is completed.
この後、回転軸２１を、支持筒１、制御盤３と共に、巻き取り済みのウェブのから抜き取り、コアレス巻き取り製品を提供できる。 Thereafter, the rotary shaft 21 together with the support cylinder 1 and the control panel 3 can be extracted from the wound web to provide a coreless wound product.
ウェブ巻取支持軸２０を用いて新たに巻き取りを行う場合には、制御盤３を回転軸２１の周囲で、矢印１０と反対の方向に回転させる。これにより、制御盤３に配備されている支持棒４ａ、４ｂ、４ｃ、４ｄ、４ｅ、４ｆ、４ｇ、４ｈも、図２、図３（ｂ）、図４（ｂ）図示の状態から、回転軸２１の周囲で、矢印１０と反対の方向に回転し、それぞれ、図１、図３（ａ）、図４（ａ）図示の状態となる。これに伴い、支持板６ａ、６ｂ、６ｃ、６ｄ、６ｅ、６ｆ、６ｇ、６ｈは、基端側の旋回穴５ａ、５ｂ、５ｃ、５ｄ、５ｅ、５ｆ、５ｇ、５ｈを支持している支持突起２ａ、２ｂ、２ｃ、２ｄ、２ｅ、２ｆ、２ｇ、２ｈの周囲に、それぞれ、矢印１１ａ、１１ｂ、１１ｃ、・・・・、１１ｈと反対の方向に旋回して図１、図４（ａ）図示の状態となる。 When a new winding is performed using the web winding support shaft 20, the control panel 3 is rotated around the rotation shaft 21 in the direction opposite to the arrow 10. As a result, the support rods 4a, 4b, 4c, 4d, 4e, 4f, 4g, and 4h arranged on the control panel 3 are also rotated from the states shown in FIGS. 2, 3 (b), and 4 (b).
