Description

本発明は、長尺のウエブを複数の巻取軸で交互に連続的に巻き取る形式の巻取装置と、その装置からウエブの巻取製品を取り外す方法に関する。   The present invention relates to a winding device of a type in which a long web is alternately and continuously wound around a plurality of winding shafts, and a method for removing a wound product from the device.

長尺のウエブを連続的に効率よく巻き取る装置として、２軸ターレット式の巻取装置が知られている。この形式の巻取装置は、ターレット軸によって間欠回転されるターレットアームと、ターレットアームに設けられた２つの巻取軸とを有し、その２つの巻取軸で交互にウエブを連続的に巻き取るものである（２つの巻取軸で交互にウエブを巻き取る巻取装置については、例えば、特許文献１、２を参照）。   As a device for continuously and efficiently winding a long web, a biaxial turret type winding device is known. This type of winding device has a turret arm intermittently rotated by a turret shaft, and two winding shafts provided on the turret arm, and the web is alternately wound around the two winding shafts alternately. (For a winding device that winds the web alternately with two winding shafts, see, for example, Patent Documents 1 and 2).

前記のような従来の巻取装置によると、連続的なウエブの巻取りを行うため、一の巻取軸によるウエブの巻取中に、ウエブの巻取りが終了した他の巻取軸からウエブの巻取製品を取り外す必要がある。   According to the conventional winding device as described above, during continuous winding of the web by one winding shaft, the web is wound from the other winding shaft where the winding of the web is completed. It is necessary to remove the winding product.

There are problems such as wobbling of the winding shaft during winding, which causes tension fluctuations and meandering of the web being wound, and wrinkles and bubbles enter the wound product of the web as the final product. is there.

巻取製品の自重は数百キログラム〜１トンに達するものもあり、このような重さのウエブの巻取製品を巻取軸から取り外す作業では、その巻取製品の自重が巻取軸に与える前述の影響（巻取軸の振れ）を皆無にするのは難しい。   The weight of the wound product may reach several hundred kilograms to 1 ton, and when removing the wound product of the web having such a weight from the winding shaft, the weight of the wound product is given to the winding shaft. It is difficult to eliminate the above-mentioned effects (winding shaft runout).

かかる影響を低減する方法として、振れを抑え込むように巻取軸を強固な設計にする方法が考えられるが、この方法によると、巻取軸の基本設計を初め、既存の巻取装置を大幅に改造しなければならず、その費用も多大なものとなる。
特開２００４−２０２５９３号公報 One way to reduce this effect is to make the take-up shaft a robust design that suppresses run-out, but this method significantly increases the existing take-up device, starting with the basic design of the take-up shaft. It must be remodeled and the cost will be significant.

The product receiving table 9 is raised by a predetermined amount until it is tilted by a set angle in the lifting direction, and the wound product FR is lifted by the product receiving table 9.

次に、前記の如く構成された本巻取装置の動作について図１、図２を用いて説明する。   Next, the operation of the winding device configured as described above will be described with reference to FIGS.

なお、以下の説明では、図１に示したように、本巻取装置Ｍの上流には、上下動可能な複数のダンサーローラ５０Ａを備えたダンサー機構部５０が設けられ、このダンサー機構部５０からガイドローラＧＲを経由して本巻取装置Ｍに当該ウエブＦが供給されるものとする。   In the following description, as shown in FIG. 1, a dancer mechanism unit 50 including a plurality of dancer rollers 50 </ b> A that can move up and down is provided upstream of the winding device M, and this dancer mechanism unit 50. It is assumed that the web F is supplied to the winding device M via the guide roller GR.

本巻取装置Ｍによると、巻取軸３によるウエブＦの巻取中に、ウエブＦの巻取りが終了した巻取軸４から巻取製品ＦＲを取り外すための準備作業を行う。この準備作業は、巻取製品ＦＲの下部に製品受取テーブル９を配置し、図示しない養生用フイルムを巻取製品ＦＲの外層に巻き付けテープで固定した後、図示しない準備完了ボタンを押下する。   According to the winding device M, during the winding of the web F by the winding shaft 3, a preparatory work for removing the wound product FR from the winding shaft 4 where the winding of the web F has been completed is performed. In this preparatory work, the product receiving table 9 is arranged below the wound product FR, a curing film (not shown) is wound around the outer layer of the wound product FR and fixed with a tape, and then a preparation completion button (not shown) is pressed.

前記準備完了ボタンの押下により、製品受取テーブル９が上昇して巻取製品ＦＲに接触する。そして、ターレットアーム２Ａ、２Ｂが図１に示す通常の位置から巻取製品ＦＲの持ち上げ方向に設定角度（例えばθ＝０．２度）だけ傾くまで、製品受取テーブル９が所定量上昇し停止する。これにより、製品受取テーブル９によって巻取製品ＦＲが持ち上げられ、巻取製品ＦＲの荷重の方向と反対向きの力が当該巻取軸４に加わり、巻取製品ＦＲの取外位置が適切な位置に調整される。   By pressing the preparation completion button, the product receiving table 9 is raised and contacts the wound product FR. Then, the product receiving table 9 rises by a predetermined amount and stops until the turret arms 2A and 2B are tilted from the normal position shown in FIG. 1 by a set angle (for example, θ = 0.2 degrees) in the lifting direction of the wound product FR. . As a result, the wound product FR is lifted by the product receiving table 9, a force opposite to the load direction of the wound product FR is applied to the winding shaft 4, and the removal position of the wound product FR is an appropriate position. Adjusted to

そして、前記のような製品受取テーブル９の上昇停止を図示しないセンサが検知し、巻取軸４のスピンドル７Ａ、７ＢをＸ２方向に移動させる動作が行われ、巻取軸４から巻取製品ＦＲが切り離されて製品受取テーブル９上に移り、巻取製品ＦＲの取外動作が完了する。その後、製品受取テーブル９が所定位置まで下降し、巻取軸４に新品の巻芯８Ａがセットされる。   Then, a sensor (not shown) detects the lifting and stopping of the product receiving table 9 as described above, and the operation of moving the spindles 7A and 7B of the winding shaft 4 in the X2 direction is performed. Is moved to the product receiving table 9, and the removal operation of the wound product FR is completed. Thereafter, the product receiving table 9 is lowered to a predetermined position, and a new core 8A is set on the winding shaft 4.

その後、巻取軸３に巻き取られているウエブＦの巻取量が設定量に達したことを図示しないセンサが検知することにより、巻取軸３が減速を開始すると同時に、ダンサーローラ５０Ａが図１に示す現在の場所（以下「原点」という）から下降を開始する。これにより、ダンサー機構部５０より上流側のウエブ供給スピードを変えることなく、ダンサー機構部５０より下流へのウエブＦの供給ラインが停止する。   Thereafter, when a sensor (not shown) detects that the winding amount of the web F wound around the winding shaft 3 has reached a set amount, the winding shaft 3 starts decelerating, and at the same time, the dancer roller 50A The descent starts from the current location shown in FIG. 1 (hereinafter referred to as “origin”). Accordingly, the supply line of the web F downstream from the dancer mechanism unit 50 is stopped without changing the web supply speed upstream of the dancer mechanism unit 50.

前記のように減速した巻取軸３の速度がゼロになると、ターレットアーム２Ａ、２Ｂが１８０度回転し、新品の巻芯８Ａをセットした巻取軸４付近で図示しないカッター装置がウエブＦを切断する。その切断されたウエブＦの一端は先ほどまでウエブＦを巻き取っていた巻取軸３の巻芯８に巻き取られ、また、切断されたウエブＦの他端は前記新品の巻芯８Ａに接着される。この接着は、予め新品の巻芯８Ａに両面テープ等（図示省略）を貼付しておき、その両面テープ等に切断されたウエブＦの他端部を押し付け接着されるようにする。この間、ダンサーローラ５０Ａは下降し続けることで、ダンサー機構部５０より下流へのウエブＦの供給ラインは停止状態を維持している。   When the speed of the winding shaft 3 decelerated as described above becomes zero, the turret arms 2A and 2B rotate 180 degrees, and a cutter device (not shown) near the winding shaft 4 on which a new core 8A is set causes the web F to move. Disconnect. One end of the cut web F is wound around the core 8 of the winding shaft 3 on which the web F has been wound up, and the other end of the cut web F is bonded to the new core 8A. Is done. For this adhesion, a double-sided tape or the like (not shown) is pasted on a new core 8A in advance, and the other end of the web F cut to the double-sided tape or the like is pressed and adhered. During this time, the dancer roller 50A continues to descend, and the supply line of the web F downstream from the dancer mechanism 50 maintains the stopped state.

以上のようにしてウエブＦが前記新品の巻芯８Ａに接着された直後、その新品の巻芯８Ａをセットしてある巻取軸４が増速を開始し、これと同時にダンサーローラ５０Ａが上昇を開始し、ダンサー機構部５０より下流へウエブＦが供給されるようになり、ダンサーローラ５０Ａが原点に復帰した時点で、巻取軸３、４の切り換えが終了する。   Immediately after the web F is bonded to the new core 8A as described above, the winding shaft 4 on which the new core 8A is set starts to accelerate, and at the same time, the dancer roller 50A is raised. Is started, the web F is supplied downstream from the dancer mechanism 50, and when the dancer roller 50A returns to the origin, the switching of the winding shafts 3 and 4 is completed.

以上説明した本実施形態の巻取装置Ｍによると、一の巻取軸３によるウエブＦの巻取中に、ウエブＦの巻取りが終了した他の巻取軸４からウエブＦの巻取製品ＦＲを取り外すときに、その巻取製品ＦＲの荷重の方向と反対向きの力を巻取軸に加えたため、巻取り中の一の巻取軸３が振れず、巻取り中のウエブＦの蛇行がなくなり、最終製品としてのウエブＦの巻取製品ＦＲに皺や気泡が入る等の不具合を防止することができるようになった。   According to the winding device M of the present embodiment described above, the winding product of the web F from the other winding shaft 4 in which the winding of the web F has been completed during the winding of the web F by the one winding shaft 3. When the FR is removed, a force opposite to the load direction of the wound product FR is applied to the winding shaft, so that one winding shaft 3 during winding does not swing, and the web F being wound is meandering. As a result, defects such as wrinkles and bubbles entering the wound product FR of the web F as the final product can be prevented.

また、本実施形態の巻取装置にあっては、巻取製品の自重が巻取軸に与える影響、すなわち巻取り中の巻取軸３の振れを防止するのにあたり、巻取製品ＦＲの荷重の方向と反対向きの力を巻取軸４に加える構成であるから、既存の巻取装置の大幅な改造や多大な費用を要することなく、かかる影響の低減を実現できる。   Further, in the winding device of the present embodiment, the load of the wound product FR is to prevent the influence of the weight of the wound product on the winding shaft, that is, to prevent the winding shaft 3 from swinging during winding. Since a force in the direction opposite to the direction is applied to the take-up shaft 4, it is possible to reduce the influence without requiring a significant modification of the existing take-up device or a great expense.

前記実施形態では、ターレットアーム２Ａ、２Ｂを通常の位置から巻取製品ＦＲの持ち上げ方向に０．２度だけ傾けるようにしたが、これは実験結果に基づくものである。実験結果によると、かかる傾きが０．２度のときに、巻芯８からスピンドル７Ａ、７Ｂを抜くときの抵抗が最も少なく、スムーズにスピンドルを抜くことができ、かつ、巻取軸４から製品受取テーブル９へ巻取製品ＦＲが移る時に、ターレットアーム２Ａ、２Ｂが全く振動せず、巻取り中のウエブＦに生じる蛇行を防止できることが判明した。なお、スピンドルや巻芯の改良により０．２度以上または０．２度以下でも巻芯からスピンドルをスムーズに抜くことが可能となれば、０．２度以上または０．２度以下の傾きを採用することもできる。   In the above-described embodiment, the turret arms 2A and 2B are inclined from the normal position by 0.2 degrees in the lifting direction of the wound product FR. This is based on experimental results. According to the experimental results, when the inclination is 0.2 degrees, the resistance when the spindles 7A and 7B are pulled out from the core 8 is the smallest, the spindle can be pulled out smoothly, and the product can be removed from the winding shaft 4. It has been found that when the wound product FR moves to the receiving table 9, the turret arms 2A and 2B do not vibrate at all, and the meandering generated on the web F during winding can be prevented. If it is possible to smoothly remove the spindle from the core even if it is 0.2 degrees or more and 0.2 degrees or less by improving the spindle or the core, an inclination of 0.2 degrees or more and 0.2 degrees or less is possible. It can also be adopted.

巻取製品ＦＲの荷重の方向と反対向きの力を巻取軸４に加える方法としては、前記制御手段１１において、製品受取テーブル９を所定量上昇させる代わりに、ターレット軸１を所定量回転させることにより、巻取製品ＦＲを製品受取テーブル９へ押し付けるようにしてもよい。この方法でも、巻取製品ＦＲの荷重の方向と反対向きの力を当該巻取軸４に加えることができ、前記実施形態と同様な作用効果が期待できる。   As a method of applying a force opposite to the direction of the load of the wound product FR to the winding shaft 4, the control means 11 rotates the turret shaft 1 by a predetermined amount instead of raising the product receiving table 9 by a predetermined amount. Thus, the wound product FR may be pressed against the product receiving table 9. Even in this method, a force opposite to the direction of the load of the wound product FR can be applied to the winding shaft 4, and the same effect as that of the above embodiment can be expected.

調整手段５の他の例（以下「第２の調整手段」という）としては、巻取製品ＦＲの下部に配置される製品受取テーブル９と、ひずみゲージ等を利用して巻取軸３、４の撓み量を検知する公知の撓み検知手段１３（図２参照）と、その撓み検知手段１３で検知される巻取軸３、４の撓み量が設定値になるまで、製品受取テーブル９を所定量上昇させる制御手段（図示省略）とからなる構成を採用することもできる。この場合も、製品受取テーブル９を所定量上昇させる代わりに、ターレット軸１を所定量回転させるようにしてもよい。   As another example of the adjusting means 5 (hereinafter referred to as “second adjusting means”), the product receiving table 9 disposed below the wound product FR, and the winding shafts 3, 4 using a strain gauge or the like. The known receiving detector 13 (see FIG. 2) for detecting the amount of bending of the product and the product receiving table 9 until the amount of bending of the winding shafts 3 and 4 detected by the bending detecting means 13 reaches a set value. A configuration comprising control means (not shown) for raising the quantity can also be adopted. Also in this case, instead of raising the product receiving table 9 by a predetermined amount, the turret shaft 1 may be rotated by a predetermined amount.

第２の調整手段は、巻取製品ＦＲの自重によって巻取軸３、４のスピンドル７Ａ、７Ｂが撓むことに着目し、その撓みをなくしてから、巻取製品ＦＲを取り外すことにしたものである。この第２の調整手段ではスピンドル７Ａ、７Ｂの撓みをなくすものであるから、前述した撓み量の設定値は０が理想である。しかしこれに限られるものではない。   The second adjusting means pays attention to the bending of the spindles 7A and 7B of the winding shafts 3 and 4 due to the weight of the winding product FR, and after removing the bending, the winding product FR is removed. It is. Since the second adjusting means eliminates the bending of the spindles 7A and 7B, the setting value of the bending amount described above is ideally zero. However, it is not limited to this.

かかる撓みをなくす手段として、第２の調整手段では、撓み検知手段１３をスピンドル７Ａ、７Ｂに設け、その撓み検知手段１３で検知した撓み量に基づいて製品受取テーブル９を所定量上昇させ、巻取製品ＦＲの荷重の方向と反対向きの力を当該巻取軸４に加えるようにした。   As a means for eliminating such bending, in the second adjusting means, the bending detection means 13 is provided on the spindles 7A and 7B, and the product receiving table 9 is raised by a predetermined amount based on the bending amount detected by the bending detection means 13, and the winding is performed. A force opposite to the load direction of the product FR was applied to the winding shaft 4.

以上説明したように、第２の調整手段でも巻取製品ＦＲの荷重の方向と反対向きの力を当該巻取軸４に加えるから、この第２の調整手段を採用した巻取装置でも前記実施形態の巻取装置と同様な作用効果が得られる。   As described above, since the second adjusting means applies a force opposite to the load direction of the wound product FR to the winding shaft 4, the winding apparatus adopting the second adjusting means also implements the above-described implementation. The same effect as that of the form winding device can be obtained.

更に、調整手段５の他の例（以下「第３の調整手段」という）としては、巻取製品ＦＲの下部に配置される製品受取テーブル９と、ロードセル等を利用して製品受取テーブル９の表面に加わる荷重を検知する荷重検知手段１４（図１参照）と、荷重検知手段１４で検知される前記荷重が設定値になるまで、製品受取テーブル９を所定量上昇させる制御手段（図示省略）とからなる構成を採用することもできる。この場合も、製品受取テーブル９を所定量上昇させる代わりに、ターレット軸１を所定量回転させるようにしてもよい。   Furthermore, as another example of the adjusting means 5 (hereinafter referred to as “third adjusting means”), a product receiving table 9 disposed below the wound product FR, and a product receiving table 9 using a load cell or the like. Load detecting means 14 (see FIG. 1) for detecting the load applied to the surface, and control means (not shown) for raising the product receiving table 9 by a predetermined amount until the load detected by the load detecting means 14 reaches a set value. The structure which consists of can also be employ | adopted. Also in this case, instead of raising the product receiving table 9 by a predetermined amount, the turret shaft 1 may be rotated by a predetermined amount.

前記荷重の設定値については、巻芯８からスピンドル７Ａ、７Ｂを抜く時の抵抗が最も少なく、スムーズにスピンドルを抜くことができる製品受取テーブル９の位置での荷重を設定値とすればよい。そのような荷重の設定値を採用した場合は、０．２度だけターレットアーム２Ａ、２Ｂを傾けたときと同様の力で巻取製品ＦＲがその荷重と反対向きに加わるから、この第３の調整手段を採用した巻取装置でも前記実施形態の巻取装置と同様な作用効果が得られる。   Regarding the set value of the load, the load at the position of the product receiving table 9 that has the least resistance when pulling the spindles 7A and 7B from the core 8 and can smoothly pull the spindle may be set as the set value. When such a set value of the load is adopted, the wound product FR is applied in the opposite direction to the load with the same force as when the turret arms 2A and 2B are inclined by 0.2 degrees. The same effect as the winding device of the above-described embodiment can be obtained even with the winding device employing the adjusting means.

また、調整手段５としては、前記傾き検知手段１０を用いた調整手段、前記撓み検知手段１３を用いた調整手段、前記荷重検知手段１４を用いた調整手段のうち、いずれか２つ以上の調整手段を組み合わせて使用してもよい。このような使用形態によると、例えば１つの調整手段が何らかの原因によって故障しても他の調整手段が正常に機能するから、障害に強く、巻取製品の取外位置を確実に調整できる等の利点がある。   Further, as the adjusting means 5, any two or more of the adjusting means using the tilt detecting means 10, the adjusting means using the deflection detecting means 13, and the adjusting means using the load detecting means 14 are adjusted. A combination of means may be used. According to such a form of use, for example, even if one adjusting means breaks down for some reason, the other adjusting means functions normally, so that it is resistant to failures and the removal position of the wound product can be adjusted reliably. There are advantages.

前記実施形態では、２つの巻取軸３、４を有する巻取装置の例について説明したが、本発明は、３以上の巻取軸を有する巻取装置にも適用できる。   In the embodiment, the example of the winding device having the two winding shafts 3 and 4 has been described. However, the present invention can also be applied to a winding device having three or more winding shafts.

本発明は例えば抄紙機、製膜機、塗工機などの巻取装置として利用することができる。   The present invention can be used as a winding device such as a paper machine, a film forming machine, and a coating machine.
