FIG. 1 is an explanatory view showing a winding process of a web material winding apparatus according to an embodiment of the present invention, FIG. 2 is an explanatory view showing a tail cutting process of the web material winding apparatus of the present invention, and FIG. FIG. 4 is an explanatory diagram showing a winding process of the web material winding device of the present invention, and FIG. 4 is an explanatory diagram showing a transfer process of the web material winding device of the present invention. Here, the web material winding device 10 includes a winding core supply unit 11 that sequentially supplies new winding cores C, a winding unit 12 that winds the leading end of the web material around the winding core, and a leading end wound around the winding core C. A winding means 16 comprising an upper winding roll 13, a lower winding roll 14 and a rider roll 15 that conveys the winding core to a winding position and applies a rotational force by contacting the winding core, and a web material when the winding is completed. And a rear cutting means 17 for the web material that forms a free end at the end of winding and a free end at the beginning of winding. The rear cutting means 17 is disposed so as to be proximate to the upper winding roll 13, and Air discharge nozzles 18 are provided in parallel along the width direction of the material.

巻取り芯供給手段１１は、供給ベルト１９に所定の間隔でガイド部材２０が取り付けられており、ガイド部材２０のそれぞれに対応して巻取り芯Ｃが載置されている。また、供給ベルト１９を張架する張架ロール２１には、送りバー２２が取り付けられており、供給ベルト１９の先端で待機している巻取り芯Ｃをタイミングに合わせて、移送プレート２３上の巻取り位置まで送り出す。   In the take-up core supply unit 11, guide members 20 are attached to the supply belt 19 at a predetermined interval, and the take-up cores C are placed corresponding to the guide members 20. Further, a feed bar 22 is attached to a tension roll 21 that stretches the supply belt 19, and the winding core C waiting at the tip of the supply belt 19 is synchronized with the timing on the transfer plate 23. Send to the winding position.

移送プレート２３上の巻取り位置では、巻き付け手段１２によってウェブ材料の先端が巻き付けられる。ウェブ材料の先端には、図外のノズル等によって接着剤が塗布されており、巻取り芯Ｃに巻き付けられる。   At the winding position on the transfer plate 23, the leading end of the web material is wound by the winding means 12. An adhesive is applied to the tip of the web material by a nozzle or the like (not shown) and is wound around the winding core C.

ウェブ材料Ｗの先端が巻き付けられた巻取り芯Ｃは、移送プレート２３上を巻取り位置まで移送される。図１、図４に示す巻取り位置では、上巻取りロール１３と下巻取りロール１４とライダーロール１５とから成る巻取り手段１６が巻取り芯Ｃの外周に接触して回転力を与え、ウェブ材料Ｗを巻き取る。   The winding core C around which the tip of the web material W is wound is transferred onto the transfer plate 23 to the winding position. In the winding position shown in FIGS. 1 and 4, the winding means 16 composed of the upper winding roll 13, the lower winding roll 14, and the rider roll 15 contacts the outer periphery of the winding core C to give a rotational force, and the web material W is wound up.

図２に示すように巻取り芯Ｃに所定長のウェブ材料が巻き取られると、図外の制御機構により上巻取りロール１３が回転を停止するとともにロールの外周面から離脱する。また、上巻取りロール１３の外周面の幅方向に形成された切断溝１３ａが後尾切断手段１７方向に移動する。一方、後尾切断手段１７は、図５に拡大して示すように圧縮エアを導くエアパイプ２４とエアパイプ２４に回動可能に外装されとともにエア吐出ノズル１８及びピンチパッド２５を備えたノズルパイプ２６から構成されている。エアパイプ２４は、上巻取りロール１３に対向した方向に切り欠き２４ａを有しており、ノズルパイプ２６が回動してエア吐出ノズル１８を上巻取りロール１３方向に向けた時に、エアパイプ２４からの圧縮エアがエア吐出ノズル１８から吐出する。切り欠き２４ａは、例えば、６０度の範囲に渡って形成されている。また、ピンチパッド２５は、エア吐出ノズル１８の先端近傍でウェブ材料の移動方向の下流側に配設されている。ピンチパッド２５は、ゴム、スポンジ、軟質合成樹脂等から構成されている。   As shown in FIG. 2, when a predetermined length of web material is wound around the winding core C, the upper winding roll 13 stops rotating and is detached from the outer peripheral surface of the roll by a control mechanism (not shown). Further, the cutting groove 13 a formed in the width direction of the outer peripheral surface of the upper winding roll 13 moves in the direction of the tail cutting means 17. On the other hand, the tail cutting means 17 is composed of an air pipe 24 that guides compressed air and a nozzle pipe 26 that is rotatably mounted on the air pipe 24 and includes an air discharge nozzle 18 and a pinch pad 25 as shown in FIG. Has been. The air pipe 24 has a notch 24 a in a direction facing the upper winding roll 13. When the nozzle pipe 26 rotates and the air discharge nozzle 18 is directed toward the upper winding roll 13, the air pipe 24 is compressed from the air pipe 24. Air is discharged from the air discharge nozzle 18. The notch 24a is formed over a range of 60 degrees, for example. The pinch pad 25 is disposed in the vicinity of the tip of the air discharge nozzle 18 on the downstream side in the moving direction of the web material. The pinch pad 25 is made of rubber, sponge, soft synthetic resin, or the like.

このように構成された後尾切断手段１７のエア吐出ノズル１８と上巻取りロール１３の幅方向に形成された切断溝１３ａが協働して、図５に示すようにウェブ材料Ｗを切断する。エア吐出ノズル１８は、ノズルパイプ２６が上巻取りロール１３の方向に向いている約６０度の範囲で圧縮エアを吐出し、それ以外の範囲では吐出することはない。また、ピンチパッド２５がウェブ材料の巻き始めの自由端となる部位を上巻取りロール１３との間で狭持し、次の工程で移送されてくる巻取り芯Ｃに巻き付ける。なお、巻き始めとなる自由端には、図外の機構により接着剤が塗布されている。   The air discharge nozzle 18 of the rear cutting means 17 configured in this way and the cutting groove 13a formed in the width direction of the upper winding roll 13 cooperate to cut the web material W as shown in FIG. The air discharge nozzle 18 discharges compressed air in the range of about 60 degrees in which the nozzle pipe 26 faces the direction of the upper winding roll 13, and does not discharge in other ranges. Further, a portion where the pinch pad 25 becomes a free end of the web material at the beginning of winding is sandwiched between the upper winding roll 13 and wound around the winding core C transferred in the next step. Note that an adhesive is applied to the free end at the beginning of winding by a mechanism not shown.

以上のように構成された本発明に係るウェブ材料の巻取り装置は、ウェブ材料Ｗをエア吐出ノズルで切断するので、ウェブ材料の切断面を綺麗に揃えることができる。したがって、ロールの端末処理を綺麗にすることができる。   Since the web material winding device according to the present invention configured as described above cuts the web material W with the air discharge nozzle, the cut surfaces of the web material can be neatly arranged. Therefore, it is possible to clean the roll terminal processing.

なお、エア吐出ノズルは、複数のノズルを幅方向に並列させた例について説明したが、他の構成であってもよい。   In addition, although the air discharge nozzle demonstrated the example which arranged the several nozzle in parallel in the width direction, another structure may be sufficient.
