Description

本発明は、帯状体の巻取装置及び巻取方法に係り、更に詳しくは、巻取軸の回転により帯状体を巻き取ることができる帯状体の巻取装置及び巻取方法に関する。   The present invention relates to a winding device and a winding method for a belt-shaped body, and more particularly to a winding device and a winding method for a belt-shaped body that can wind the belt-shaped body by rotating a winding shaft.

従来より、接着シートが剥離された後の剥離シート等からなる帯状体を巻き取り可能な巻取装置が広く利用されている。かかる巻取装置としては、帯状体を巻き取る巻取軸と、この巻取軸を回転させる駆動手段とを備えたものが知られている(特許文献1参照)。巻取軸による帯状体の巻き取りにおいて、巻き取り当初から、巻取軸の回転速度を速くしたり回転トルクを大きくしたりすると、帯状体が巻取軸にきつく巻き取られ、当該巻取軸に巻き付いた帯状体を取り外すことが困難になる。一方、巻取軸の回転速度を遅くしたり回転トルクを小さくしたりすると、巻き取り中、巻取軸に巻き取られた帯状体が型崩れして巻き取り不良の原因となる。更に、図2に示されるように、巻取軸50の近傍に、帯状体RLの繰り出しを行うための駆動ローラ52及びピンチローラ53が配置される場合、ピンチローラ53から巻取軸50へ向かう帯状体RLが弛むばかりでなく(同図中二点鎖線参照)、弛んだ帯状体RLが駆動ローラ52とピンチローラ53との間に巻き込まれ、これによっても巻き取り不良が発生する場合がある。   2. Description of the Related Art Conventionally, a winding device that can wind up a belt-like body made of a release sheet or the like after an adhesive sheet has been peeled has been widely used. As such a winding device, one having a winding shaft for winding a belt-like body and a driving means for rotating the winding shaft is known (see Patent Document 1). When winding the belt-like body with the winding shaft, if the rotational speed of the winding shaft is increased or the rotational torque is increased from the beginning of winding, the belt-like body is tightly wound around the winding shaft, and the winding shaft It becomes difficult to remove the belt wound around. On the other hand, if the rotational speed of the winding shaft is slowed or the rotational torque is reduced, the belt-like body wound around the winding shaft will lose its shape during winding and cause winding failure. Further, as shown in FIG. 2, when the driving roller 52 and the pinch roller 53 for feeding the strip RL are arranged in the vicinity of the take-up shaft 50, the pinch roller 53 goes to the take-up shaft 50. Not only is the belt-like body RL slackened (see the two-dot chain line in the figure), but the slackened belt-like body RL is caught between the driving roller 52 and the pinch roller 53, and this may cause a winding failure. .

ここで、巻取軸による帯状体の巻き取りを良好に行うべく、巻取軸の回転速度や回転トルクが次第に大きくなるように予め設定して当該回転を制御する方法(以下、「従来方法A」と称する)が考えられる。これによれば、巻取軸に巻き取られた帯状体の巻取径の増大に伴う、巻き取り速度や回転トルクの低下を抑制することが可能となる。   Here, in order to satisfactorily wind the belt-like body with the winding shaft, a method of controlling the rotation by setting in advance so that the rotational speed and torque of the winding shaft gradually increase (hereinafter referred to as “conventional method A”). "). According to this, it is possible to suppress a decrease in the winding speed and the rotational torque accompanying an increase in the winding diameter of the belt-like body wound around the winding shaft.

ところで、例えば、図3に示される巻取軸60のように、ピン60Aを用いて帯状体RLのリード端側を固定するタイプの場合、帯状体RLが円形でなくカム形となって巻き取られて径寸法R1、R2が不均一となる。同図の巻取軸60を用いて、従来方法Aにより巻き取りを行った場合、径寸法R1、R2の変化によって巻き取り速度や回転トルクが巻き取り前の帯状体RLに理想通りに伝わらず、結果として巻き取り不良を回避することが困難になる、という不都合がある。   By the way, in the case of a type in which the lead end side of the strip RL is fixed using a pin 60A as in the winding shaft 60 shown in FIG. 3, for example, the strip RL is not circular but is wound in a cam shape. As a result, the diameters R1 and R2 are not uniform. When winding is performed by the conventional method A using the winding shaft 60 of the figure, the winding speed and the rotational torque are not transmitted to the strip-shaped body RL before winding as ideal due to changes in the diameter dimensions R1 and R2. As a result, there is an inconvenience that it is difficult to avoid winding failure.

ここで、特許文献2にあっては、巻き取られた帯状体に接するタッチロールを備えたセンサにより当該帯状体の巻取径を認識し、帯状体の張力が一定となるように巻取軸の回転を制御するようになっている。
しかしながら、同文献にあっては、タッチロール等により装置全体が大型化するばかりでなく、材料の巻径によって回転速度や回転トルクをいくつに設定するといったデータが必要であり、材料が変更になる度にその材料に適合するデータを入れ替えなければならず、制御が複雑になって多大な労力を費やさなければならない、という不都合を招来する。
Here, in Patent Document 2, a winding shaft that recognizes the winding diameter of the belt-like body by a sensor having a touch roll in contact with the wound belt-like body so that the tension of the belt-like body is constant. The rotation is controlled.
However, in the same document, not only the size of the entire apparatus is increased by a touch roll or the like, but also data such as how many rotation speeds and rotation torques are set depending on the winding diameter of the material is necessary, and the material is changed. Each time, the data suitable for the material must be replaced, resulting in inconvenience that the control becomes complicated and a great deal of labor must be expended.

[発明の目的]
本発明は、このような不都合に着目して案出されたものであり、その目的は、巻取軸での帯状体を巻き取るときに巻取不良を防止することができ、且つ、装置全体の小型化、制御の簡略化を図ることができる帯状体の巻取装置及び巻取方法を提供することにある。
[Object of invention]
The present invention has been devised by paying attention to such inconveniences, and an object of the present invention is to prevent winding failure when winding a belt-like body on a winding shaft, and the entire apparatus. It is an object of the present invention to provide a winding device and a winding method for a belt-like body capable of reducing the size and simplifying the control.

前記目的を達成するため、本発明は、送り動作と停止とを所定間隔で繰り返すことで間欠送りされる帯状体に対し、当該帯状体の送り動作中に停止する一方、当該帯状体の停止中に当該帯状体を所定長さ巻き取ることで間欠巻取り可能な巻取軸と、この巻取軸に回転力を付与する駆動手段と、前記巻取軸の前段で前記帯状体に張力を付与するとともに、前記帯状体の間欠送りと間欠巻取りによって変位される変位体を有する張力付与手段と、前記駆動手段の回転速度及び又は回転トルクを制御する機能と、前記変位体の変位時間を計測する機能とを含む制御手段とを備え、
前記制御手段は、前回の巻取軸による帯状体の巻き取りによって所定タイミング間で変位体が変位する変位時間を基に、次回の駆動手段の回転速度及び又は回転トルクを決定する、という構成を採っている。
In order to achieve the above object, the present invention stops the belt-like body intermittently fed by repeating the feeding operation and the stop at a predetermined interval while stopping the belt-like body while the belt-like body is stopped. A winding shaft that can be intermittently wound by winding the belt-like body for a predetermined length, a driving means that applies a rotational force to the winding shaft, and tension that is applied to the belt-like body before the winding shaft. In addition, the tension applying means having a displacement body displaced by intermittent feeding and intermittent winding of the belt-like body, the function of controlling the rotational speed and / or rotational torque of the driving means, and the displacement time of the displacement body are measured. And a control means including a function to
The control means determines the rotational speed and / or rotational torque of the next drive means on the basis of the displacement time during which the displacement body is displaced during a predetermined timing due to the winding of the belt-like body by the previous winding shaft. Adopted.

本発明において、前記変位体の位置を検出可能な検出手段を更に備える、という構成を採ることが好ましい。   In the present invention, it is preferable to employ a configuration further including a detection unit capable of detecting the position of the displacement body.

また、前記制御手段は、前回の変位体の変位時間を直前変位時間として基準時間と比較し、直前変位時間が基準時間より長い場合、次回の駆動手段の回転速度及び又は回転トルクを大きくする一方、直前変位時間が基準時間より短い場合、次回の駆動手段の回転速度及び又は回転トルクを小さくするよう制御する、という構成を採ってもよい。   Further, the control means compares the displacement time of the previous displacement body as the previous displacement time with the reference time, and if the previous displacement time is longer than the reference time, it increases the rotational speed and / or the rotational torque of the next drive means. When the previous displacement time is shorter than the reference time, a configuration may be adopted in which control is performed to reduce the rotational speed and / or rotational torque of the next drive means.

また、本発明の巻取方法は、送り動作と停止とを所定間隔で繰り返すことで帯状体を間欠送りする工程と、前記間欠送りされる帯状体に対して、駆動手段によって駆動されるとともに、前記帯状体の送り動作中に停止する一方、当該帯状体の停止中に当該帯状体を所定長さ巻取軸で巻き取ることで間欠巻取する工程と、前記巻取軸の前段で前記帯状体に張力を付与するとともに、前記帯状体の間欠送りと間欠巻取りによって変位される変位体を用いて張力を付与する工程と、前回の巻取軸による帯状体の巻き取りによって所定タイミング間で変位体が変位する変位時間を計測する工程と、計測された変位時間を基に、次回の駆動手段の回転速度及び又は回転トルクを決定する工程と、決定された回転速度及び又は回転トルクで駆動手段を駆動して巻取軸で帯状体を巻き取る工程とを行う、という方法を採っている。   Further, the winding method of the present invention is a step of intermittently feeding the belt-like body by repeating the feeding operation and stop at a predetermined interval, and the intermittently fed belt-like body is driven by a driving means, While the belt-like body is stopped during the feeding operation, the belt-like body is intermittently wound by winding the belt-like body with a winding shaft of a predetermined length while the belt-like body is stopped; Applying tension to the body and applying tension using a displacement body that is displaced by intermittent feeding and intermittent winding of the belt-like body, and winding of the belt-like body by the previous winding shaft between predetermined timings The step of measuring the displacement time for which the displacement body is displaced, the step of determining the rotational speed and / or rotational torque of the next drive means based on the measured displacement time, and the driving at the determined rotational speed and / or rotational torque Driving means Performing the step of winding the strip in the winding shaft Te, it adopts a method called.

本発明によれば、帯状体に張力を付与する変位体の変位時間を計測して駆動手段を制御するので、従来のタッチロールを省略でき、装置のコンパクト化を図ることができる。また、変位体の変位時間を計測するので、当該変位時間から巻取径の変化に応じた帯状体の巻き取り速度や回転トルクの変化を容易に検出できる。これにより、帯状体の巻取径が変化しても張力を安定して一定に保つことができ、前述した巻取軸への巻き取り不良等を解消することが可能となる。
また、前回の帯状体の巻き取りによって所定タイミング間で変位体が変位する変位時間を基に、次回の駆動手段の回転速度及び又は回転トルクを決定するだけなので、材料の巻径によって回転速度や回転トルクをいくつに設定するといったデータは必要なくなり、それに伴う制御の複雑化を回避して制御の簡略化を図ることができる。
According to the present invention, since the displacement means for applying tension to the belt-like body is measured to control the driving means, the conventional touch roll can be omitted, and the apparatus can be made compact. Further, since the displacement time of the displacement body is measured, it is possible to easily detect the change in the winding speed and the rotational torque of the belt-like body according to the change in the winding diameter from the displacement time. Thereby, even if the winding diameter of the belt-like body changes, the tension can be kept stable and constant, and the above-described defective winding onto the winding shaft can be solved.
In addition, since the rotational speed and / or rotational torque of the next drive means is only determined on the basis of the displacement time during which the displacement body is displaced at a predetermined timing by the previous winding of the belt-like body, the rotational speed or Data such as how many rotational torques are set is no longer necessary, and the control can be simplified by avoiding complication of the control.

次に、本実施形態の全体的な動作について説明する。   Next, the overall operation of this embodiment will be described.

初期作業として、支持軸22に支持された原反Rを所定長さ引き出し、図1に示されるように、ピールプレート13の先端で折り返すように原反Rを掛け回した後、駆動ローラ23とピンチローラ24との間に原反Rを通過させ、更に、ダンサローラ38の下方に原反Rを掛け回した後、当該原反Rのリード端を巻取軸32に固定する。このとき、変位体37は、ばね部材40により図1中二点鎖線で示される符号P0で示した位置(戻り限)に位置している。   As an initial operation, the original fabric R supported by the support shaft 22 is pulled out by a predetermined length, and as shown in FIG. 1, the original fabric R is wound around so as to be folded back at the tip of the peel plate 13. The original fabric R is passed between the pinch roller 24 and the original fabric R is wound around the dancer roller 38, and then the lead end of the original fabric R is fixed to the winding shaft 32. At this time, the displacement body 37 is located at the position (return limit) indicated by the symbol P0 indicated by the two-dot chain line in FIG.

その後、図示しない起動スイッチによって電源が供給されると、モータM2の回転をロックして停止させた状態で、モータM1によって駆動ローラ23を回転させ、原反Rを繰り出しつつ、印字ヘッド26により1枚目の接着シートS1に印字を施す。このとき、ピンチローラ24と巻取軸32との間の剥離シートRLは、符号P0で示した位置にあるダンサローラ38の下方に弛むように繰り出される。次いで、1枚目の接着シートS1がピールプレート13の先端側に設けられたセンサSeにより検出され、この検出結果が制御手段36に入力された時点でモータM1の回転をロックして原反Rの繰り出しを停止させると同時に、モータM2によって巻取軸32を回転させて剥離シートRLを巻き取る。これにより、ピンチローラ24と巻取軸32との間の剥離シートRLは、ダンサローラ38の下方で弛んだ分が巻き取られた後、ダンサローラ38に当接し、ばね部材40の付勢力に抗して変位体37を時計回りに変位させる。そして、図1中符号P1で示した位置まで変位体37が変位すると、センサ35によりアーム39が検出され、この検出結果が制御手段36に入力された時点でモータM2の回転をロックして停止させることで、シート貼付装置10がスタンバイ状態となる。   Thereafter, when power is supplied by a start switch (not shown), while the rotation of the motor M2 is locked and stopped, the driving roller 23 is rotated by the motor M1, and the print head 26 feeds out the original fabric R, while Printing is performed on the first adhesive sheet S1. At this time, the release sheet RL between the pinch roller 24 and the take-up shaft 32 is fed out so as to be loosened below the dancer roller 38 at the position indicated by the symbol P0. Next, when the first adhesive sheet S1 is detected by the sensor Se provided on the front end side of the peel plate 13, and when the detection result is input to the control means 36, the rotation of the motor M1 is locked and the original fabric R At the same time, the take-up shaft 32 is rotated by the motor M2, and the release sheet RL is taken up. As a result, the release sheet RL between the pinch roller 24 and the take-up shaft 32 is wound up below the dancer roller 38 and then comes into contact with the dancer roller 38 to resist the urging force of the spring member 40. The displacement body 37 is displaced clockwise. When the displacement body 37 is displaced to the position indicated by the reference symbol P1 in FIG. 1, the arm 39 is detected by the sensor 35, and when the detection result is input to the control means 36, the rotation of the motor M2 is locked and stopped. By doing so, the sheet sticking apparatus 10 enters a standby state.

そして、搬送手段19によって、図1中左方向に向かって被着体Wが搬送されると、図示しないセンサによって検出され、吸着ヘッド29の下方の所定位置で停止する。次いで、モータM2の回転をロックしたまま、モータM1によって駆動ローラ23を回転させることで、原反Rが繰り出され、1枚目の接着シートS1がピールプレート13の先端で剥離シートRLから剥離されて吸着ヘッド29により吸着保持される。次いで、直動モータ30によって吸着ヘッド29を下降させ、吸着ヘッド29の吸着を解除して初期位置に復帰させることで、1枚目の接着シートS1を被着体Wの上面に押圧して貼付する。   Then, when the adherend W is transported leftward in FIG. 1 by the transport means 19, it is detected by a sensor (not shown) and stops at a predetermined position below the suction head 29. Next, while the rotation of the motor M2 is locked, the driving roller 23 is rotated by the motor M1 so that the original fabric R is unwound and the first adhesive sheet S1 is peeled from the peeling sheet RL at the tip of the peel plate 13. And sucked and held by the suction head 29. Next, the suction head 29 is lowered by the linear motor 30 to release the suction of the suction head 29 and return it to the initial position, thereby pressing and sticking the first adhesive sheet S1 to the upper surface of the adherend W. To do.

なお、1枚目の接着シートS1の繰り出しによって印字ヘッド26の下方を通過した2枚目の接着シートS2は、印字ヘッド26によって印字が施された後、センサSeによって検出され、シート検知タイミングでモータM1の回転がロックされて原反Rの繰り出しが停止される(間欠送り工程)。このとき、ピンチローラ24と巻取軸32との間に繰り出された剥離シートRLによって、変位体37は、巻取軸32の中心を回転中心として図1中下方に変位され、図1中二点鎖線で示されるP2で示した位置に達する。また、シート検知タイミングでモータM2によって巻取軸32を回転させると、ピンチローラ24と巻取軸32との間に繰り出された剥離シートRLが巻き取られ(間欠巻取り工程)、変位体37が図1中上方に変位されてセンサ35によりアーム39が検出され、変位体検知タイミングでモータM2の回転がロックされて原反Rの巻き取りが停止される。これにより、1回の接着シートSの貼付動作が完了し、前述の制御を繰り返し行うことで接着シートSの貼付間隔毎に、変位体37がP1とP2との間を1往復することとなる。   The second adhesive sheet S2 that has passed under the print head 26 by feeding the first adhesive sheet S1 is detected by the sensor Se after printing by the print head 26, and at the sheet detection timing. The rotation of the motor M1 is locked, and the feeding of the raw material R is stopped (intermittent feed process). At this time, due to the release sheet RL fed between the pinch roller 24 and the take-up shaft 32, the displacement body 37 is displaced downward in FIG. 1 with the center of the take-up shaft 32 as the center of rotation. The position indicated by P2 indicated by the dotted line is reached. When the take-up shaft 32 is rotated by the motor M2 at the sheet detection timing, the release sheet RL fed between the pinch roller 24 and the take-up shaft 32 is taken up (intermittent take-up process), and the displacement body 37 is moved. 1 is displaced upward in FIG. 1, the arm 39 is detected by the sensor 35, the rotation of the motor M2 is locked at the displacement body detection timing, and the winding of the original fabric R is stopped. Thereby, the sticking operation of one adhesive sheet S is completed, and the displacement body 37 reciprocates once between P1 and P2 for every sticking interval of the adhesive sheet S by repeating the above-described control. .

ここで、制御手段36は、接着シートSの貼付間隔毎に変位体37がP2からP1に復帰するまでの変位時間、すなわち、シート検知タイミングから、変位体検知タイミングまでの所定タイミング間の時間を計測する。次いで、計測された変位時間(以下、「直前変位時間」と称する)を基に、次回の間欠巻取りにおけるモータM2の回転速度や回転トルクを制御手段36で決定する。   Here, the control means 36 calculates the displacement time until the displacement body 37 returns from P2 to P1 at every application interval of the adhesive sheet S, that is, the time between the predetermined timing from the sheet detection timing to the displacement body detection timing. measure. Next, based on the measured displacement time (hereinafter referred to as “immediate displacement time”), the control means 36 determines the rotational speed and rotational torque of the motor M2 in the next intermittent winding.

具体的には、先ず、直前変位時間と、予め設定した基準時間とを比較する。なお、基準時間は、ピンチローラ24と巻取軸32との間の剥離シートRLが適度な張力となる際の変位時間とされ、オペレータによって予め制御手段36に入力されている。比較の結果、直前変位時間が基準時間より長い場合、次回の間欠巻取りにおけるモータM2の回転速度及び又は回転トルクが直前の接着シートSの貼付における間欠巻取りより相対的に大きくなるように制御する一方、直前変位時間が基準時間より短い場合、モータM2の回転速度及び又は回転トルクが直前の接着シートSの貼付における間欠巻取りより相対的に小さくなるように制御される。回転速度や回転トルクの変化量は、例えば、比較した直前変位時間と基準時間との差に比例して増減させてもよい。次回の間欠巻取りにおけるモータM2の回転速度及び又は回転トルクが決定すると、これに応じてモータM2による巻取軸32の回転速度及び又は回転トルクが制御され、剥離シートRLの巻き取りが行われる。   Specifically, first, the previous displacement time is compared with a preset reference time. The reference time is a displacement time when the release sheet RL between the pinch roller 24 and the take-up shaft 32 has an appropriate tension, and is input to the control means 36 in advance by the operator. As a result of the comparison, when the previous displacement time is longer than the reference time, control is performed so that the rotational speed and / or rotational torque of the motor M2 in the next intermittent winding is relatively larger than the intermittent winding in the pasting of the immediately preceding adhesive sheet S. On the other hand, when the previous displacement time is shorter than the reference time, the rotational speed and / or rotational torque of the motor M2 is controlled to be relatively smaller than the intermittent winding in the pasting of the immediately preceding adhesive sheet S. For example, the amount of change in the rotation speed or the rotation torque may be increased or decreased in proportion to the difference between the compared previous displacement time and the reference time. When the rotational speed and / or rotational torque of the motor M2 in the next intermittent winding is determined, the rotational speed and / or rotational torque of the winding shaft 32 by the motor M2 is controlled accordingly, and the release sheet RL is wound. .

従って、このような実施形態によれば、変位体37の変位時間を計測して巻取軸32の回転速度や回転トルク等を制御するので、装置全体を構成する部品点数の削減、装置の小型化を図ることができる。また、巻き取られた剥離シートRLが円形にならずにカム形等になって巻取径が不均一になっても、これに伴う剥離シートRLの巻き取り速度や回転トルクの変化を容易に検出でき、巻取軸32への剥離シートRLの巻き付け力を常時良好に保って剥離シートRLの巻き取り不良を防止することが可能となる。   Therefore, according to such an embodiment, the displacement time of the displacement body 37 is measured to control the rotational speed, the rotational torque, and the like of the winding shaft 32. Therefore, the number of parts constituting the entire apparatus is reduced, and the apparatus is downsized. Can be achieved. In addition, even when the wound release sheet RL is not circular but has a cam shape or the like and the winding diameter becomes non-uniform, it is easy to change the winding speed and rotational torque of the release sheet RL. It can be detected, and the winding force of the release sheet RL around the take-up shaft 32 can be kept good at all times to prevent winding failure of the release sheet RL.
