Description

この発明は、剥離シートとその上に付着した粘着剤付きラベル用紙とを有する帯状のラベルシートのラベル用紙にその長手方向に沿ってラベル抜き加工とラベル印刷とを繰り返し施して粘着剤付きラベルを多数製作する際に用いられ、ラベル用紙にラベル抜き加工とラベル印刷とを施した後のラベルシートの剥離シート上からラベルの周囲の連続的な梯子状の枠部だけを剥がし、粘着剤付きのラベルが付着したまま残った剥離シートと、粘着剤付きの梯子状の枠部とを別途に巻き取るシート巻取り装置に関するものである。 The present invention provides a label with a pressure-sensitive adhesive by repeatedly performing label cutting processing and label printing on a label paper of a strip-shaped label sheet having a release sheet and a label paper with a pressure-sensitive adhesive adhered onto the release sheet. It is used when making a large number, and after peeling off the label sheet and label printing on the label paper, peel off only the continuous ladder-shaped frame around the label from the release sheet, The present invention relates to a sheet winding device that separately winds a release sheet on which a label remains attached and a ladder-shaped frame portion with an adhesive.

ラベル印刷においてフチなし印刷と呼ばれる方式は、図柄をラベルから周囲にはみ出させて印刷するため、剥離シートとその上に付着した粘着剤付きラベル用紙とを有する帯状のラベルシートにその長手方向に沿って、ラベルの輪郭をハーフカット状態で切り抜くラベル抜き加工を繰り返し施した後、ラベルからはみ出すインクの受け皿としてラベルの周囲に設けた、一般に「カス」と呼ばれる連続的な梯子状の枠部をラベルと一緒に剥離シート上に残したままでラベルシートをロール状に巻き、そのラベルシートロールをラベルプリンタに装填してそこからラベルシートを繰り出しながらラベル用紙にラベル印刷を行う。 In a method called borderless printing in label printing, since a pattern is printed by protruding from the label to the periphery, a strip-shaped label sheet having a release sheet and a label sheet with an adhesive adhered on the release sheet is arranged along the longitudinal direction thereof. After repeating the label cutting process to cut out the outline of the label in a half-cut state, a continuous ladder-shaped frame portion generally called "cass" is provided around the label as a tray for the ink protruding from the label. The label sheet is wound in a roll shape while being left on the release sheet together with, and the label sheet roll is loaded into the label printer, and the label sheet is unwound from the label sheet to perform label printing on the label sheet.

このためラベル印刷後のラベルは、枠部で囲まれていて剥離シートから剥がしにくい状態となっており、それゆえ、被着物への粘着剤付きラベルの貼付けの際にラベルを剥離シートから剥がし易くするには、上記ラベル印刷後のラベルシートの剥離シートから粘着剤付き枠部だけを剥がして分離させる必要がある。 For this reason, the label after printing the label is surrounded by the frame part and is in a state of being difficult to peel from the release sheet, and therefore, when the label with the adhesive is attached to the adherend, the label is easily peeled from the release sheet. In order to do so, it is necessary to peel off only the frame portion with the adhesive from the release sheet of the label sheet after the label printing to separate it.

ところで従来、ラベル印刷後の粘着剤付きラベルを剥離シートから剥がして分離させ、そのラベルを被着物に貼り付けるとともに、ラベルを剥がした剥離シートをロール状に巻き取るラベル貼付け装置が例えば特許文献１にて知られており、このラベル貼付け装置は、枠部を剥がして粘着剤付きラベルだけを剥離シート上に残した帯状のラベルシートをロール状に巻いたラベルシートロールを支持するシートロール支持手段と、そのラベルシートロールから粘着剤付きラベルだけが剥離シート上に付着したラベルシートを繰り出すラベルシート繰出し手段と、その繰り出したラベルシートの剥離シート上に付着した粘着剤付きラベルを剥離シートから１枚ずつ剥がすラベル剥離手段と、その剥離シートから剥がした粘着剤付きラベルを被着物に押圧して付着させるラベル付着手段と、粘着剤付きラベルを剥がした剥離シートを巻き取る剥離シート巻取り手段とを具えている。 By the way, conventionally, a label sticking device that peels a label with a pressure-sensitive adhesive after label printing from a release sheet to separate the label and attaches the label to an adherend and winds the release sheet from which the label has been peeled off into a roll shape is disclosed in Patent Document 1, for example. This label applying device is a sheet roll supporting means for supporting a label sheet roll in which a strip-shaped label sheet in which a frame portion is peeled off and only a label with an adhesive is left on a release sheet is wound in a roll shape. A label sheet feeding means for feeding only the label sheet with the adhesive attached onto the release sheet from the label sheet roll, and the label with the adhesive attached on the release sheet of the delivered label sheet from the release sheet. Label peeling means for peeling one by one, label sticking means for sticking the pressure-sensitive adhesive label peeled off from the peeling sheet to the adherend, and peeling sheet winding means for winding the peeling sheet peeling off the pressure-sensitive adhesive label It has

ここで、ラベルシート繰出し手段は、モータで駆動ローラを回転駆動して、粘着剤付きラベルが剥離シート上に付着したラベルシートをその駆動ローラとピンチローラとの間に挟んで引いてラベルシートロールから繰り出し、剥離シート巻取り手段は、モータで駆動軸を回転駆動して、その駆動軸に基端部を連結するとともに駆動軸の軸線周りに等間隔に配置した複数本の巻取り部材上に、粘着剤付きラベルを剥がした剥離シートを巻き取るように構成しており、その剥離シートを巻き取った剥離シートロールの保持と容易な抜き取り除去とを可能にするため、複数本の巻取り部材の先端部は各々、駆動軸の軸線上に配置された円錐状の調整部材と摺接し、その調整部材の軸線方向移動によって、それらの巻取り部材の先端部の、駆動軸の軸線を中心とした配置円を拡縮径可能としている。 Here, the label sheet roll-out means rotates the drive roller by a motor, pulls the label sheet with the adhesive label attached on the release sheet by sandwiching it between the drive roller and the pinch roller, and pulling the label sheet roll. The release sheet winding means is configured to rotate the drive shaft by a motor, connect the base end portion to the drive shaft, and dispose on a plurality of winding members arranged at equal intervals around the axis of the drive shaft. , A plurality of winding members configured to wind a release sheet from which a label with an adhesive has been peeled off and to enable holding of a release sheet roll having the release sheet wound thereon and easy removal and removal. The tip end of each of the sliding contact with the conical adjustment member arranged on the axis of the drive shaft, and by the axial movement of the adjustment member, the tip end of these winding members is centered on the axis of the drive shaft. The arranged circle can be expanded/contracted.

しかしながら上記従来の巻取り手段は、ラベルシート繰出し手段の駆動ローラの駆動用のモータと、剥離シート巻取り手段の駆動軸の駆動用のモータとをそれぞれ設け、剥離シート巻取り手段での剥離シートの巻取りが進むにつれて増大する巻取り径での巻取り速度がラベルシート繰り出し手段でのラベルシートの繰り出し速度に対応するように、剥離シート巻取り手段の駆動用モータの回転速度とラベルシート繰り出し手段の駆動用モータの回転速度とを制御する必要があることから、二つのモータとそれらの制御装置とにコストが嵩むという問題があった。 However, the conventional winding means is provided with a motor for driving the drive roller of the label sheet feeding means and a motor for driving the drive shaft of the peeling sheet winding means, respectively, and the peeling sheet in the peeling sheet winding means is provided. So that the take-up speed at the take-up diameter that increases as the take-up of the sheet corresponds to the take-up speed of the label sheet by the label sheet take-up means, the rotation speed of the drive motor of the release sheet take-up means and the label sheet take-out Since it is necessary to control the rotation speed of the driving motor of the means, there is a problem that the cost of the two motors and their control devices increases.

さらに、上記従来の剥離シート巻取り手段は、複数本の巻取り部材の先端部の配置円を円錐状の調整部材との摺接で拡縮径させているので、剥離シートを巻き取った剥離シートロールの取り外しの際は調整部材を充分に移動させる必要があって手間がかかるという問題もあった。 Further, in the above-mentioned conventional release sheet winding means, the arrangement circle of the tip end portions of the plurality of winding members is expanded/contracted by sliding contact with the conical adjustment member. When removing the roll, it is necessary to move the adjustment member sufficiently, which is troublesome.

この発明のシート巻取り装置にあっては、剥離シートとその上に付着した粘着剤付きラベル用紙とを有し、その粘着剤付きラベル用紙にその長手方向に沿って例えばカッターローラによりラベル抜き加工が繰り返し施されるとともにプリンタによりラベル印刷が繰り返し施されて粘着剤付きラベルが多数形成された帯状のラベルシートを、例えばそのプリンタから、各々回転自在に支持された二本の分離ローラの間に供給すると、それらの分離ローラが、そのラベルシートの剥離シートとその剥離シート上の枠部とをそれぞれの分離ローラの外周面に沿う方向に案内して、粘着剤付きラベルを剥離シート上に付着したまま残したラベルシートと、剥離シート上から剥がした前記枠部とを互いに離間する方向へ送り出し、ラベルシート巻取り軸が、それら二本の分離ローラから送り出された、粘着剤付きラベルを剥離シート上に付着したまま残したラベルシートを巻き取るとともに、枠部巻取り軸が、それら二本の分離ローラから送り出された枠部を巻き取り、単一のモータが、それらラベルシート巻取り軸と枠部巻取り軸とを一緒に回転駆動し、そして伝動機構が、前記モータの出力軸の回転を、ラベルシート巻取り軸と枠部巻取り軸とにそれぞれ伝動するとともに、枠部巻取り軸に対しては滑り締結状態の機械式摩擦クラッチを介して伝動して、枠部巻取り軸による枠部の巻取り速度をラベルシート巻取り軸によるラベルシートの巻取り速度に対応させる。 In the sheet winding device of the present invention, it has a release sheet and a label sheet with an adhesive adhered onto the release sheet, and the label sheet with the adhesive is label-punched with a cutter roller along its longitudinal direction. Is repeatedly applied, and label printing is repeatedly performed by a printer, and a strip-shaped label sheet on which a large number of labels with adhesives are formed is, for example, from the printer, between two rotatably supported separation rollers. When supplied, the separation rollers guide the release sheet of the label sheet and the frame portion on the release sheet in the direction along the outer peripheral surface of each separation roller to attach the adhesive label to the release sheet. The label sheet left as it is and the frame portion peeled off from the release sheet are sent out in a direction in which they are separated from each other, and the label sheet take-up shaft peels off the adhesive-attached label sent out from the two separating rollers. The label sheet that remains attached on the sheet is rolled up, and the frame winding shaft rolls up the frame fed from the two separating rollers, and the single motor drives the label sheet winding shaft. And the frame portion winding shaft are driven together, and a transmission mechanism transmits the rotation of the output shaft of the motor to the label sheet winding shaft and the frame portion winding shaft, respectively, and at the same time, the frame portion winding shaft. Power is transmitted to the shaft through a mechanical friction clutch in a slip-fastened state, and the winding speed of the frame portion by the frame winding shaft corresponds to the label sheet winding speed by the label sheet winding shaft.

従って、この発明のシート巻取り装置によれば、単一のモータでラベルシート巻取り軸と枠部巻取り軸とを一緒に回転駆動し、しかも滑り締結状態の機械式摩擦クラッチによる伝動で、枠部巻取り軸による枠部の巻取り速度を、枠部やラベルシートの増大する巻取り径の相違にかかわらず、ラベルシート巻取り軸によるラベルシートの巻取り速度に対応させるので、ラベルシートの剥離シートから粘着剤付きラベルの周囲の連続的な梯子状の枠部だけを剥がして分離させ、粘着剤付きラベルを剥離シート上に付着したまま残した帯状のラベルシートと粘着剤付き枠部とを別途に巻き取るシート巻取り装置を、簡易且つ安価に構成することができる。 Therefore, according to the sheet winding device of the present invention, the label sheet winding shaft and the frame portion winding shaft are rotationally driven together by a single motor, and further, by the transmission by the mechanical friction clutch in the slip-fastened state, Since the take-up speed of the frame portion by the frame take-up shaft is made to correspond to the take-up speed of the label sheet by the label sheet take-up shaft, regardless of the difference in the take-up diameter of the frame portion or the label sheet, Only the continuous ladder-shaped frame around the label with adhesive is peeled off from the release sheet to separate it, and the strip-shaped label sheet and the frame with adhesive are left on the release sheet. A sheet winding device for separately winding and can be configured easily and inexpensively.

さらに、この発明のシート巻取り装置においては、前記機械式摩擦クラッチは、前記伝動機構の、前記枠部巻取り軸に前記モータの出力軸の回転を伝動する回転部材と前記枠部巻取り軸との間に円筒状の滑り部材を介挿するとともに、それら回転部材と滑り部材とをそれぞれ、軸線方向に延在する切れ目を設けて弾性的に拡縮径可能とし、前記回転部材の前記切れ目と交差する位置に、締め込みによってその切れ目を縮小させて前記回転部材と前記滑り部材とを縮径させ、前記回転部材と前記枠部巻取り軸との滑り締結力を強めるねじ部材を設けたものとする。 Further, in the sheet winding device of the present invention, the mechanical friction clutch includes a rotating member that transmits rotation of the output shaft of the motor to the frame winding shaft of the transmission mechanism, and the frame winding shaft. While inserting a cylindrical sliding member between and, the rotating member and the sliding member, respectively, to provide a slit extending in the axial direction to allow elastic expansion and contraction of the diameter, and the slit of the rotating member. A screw member is provided at the intersecting position so as to reduce the cut by tightening to reduce the diameter of the rotating member and the sliding member and strengthen the sliding fastening force between the rotating member and the frame portion winding shaft. And

このように機械式摩擦クラッチを構成することで、安価な構成で、滑り締結状態を確実に得ることができ、しかもねじ部材の締め込みあるいは緩めで滑り締結力を適宜調整することができる。 By constructing the mechanical friction clutch in this manner, the slip-engaged state can be reliably obtained with an inexpensive structure, and the slip-engagement force can be appropriately adjusted by tightening or loosening the screw member.

なお、この発明のシート巻取り装置においては、前記伝動機構は、前記モータの出力軸に結合した駆動プーリと、前記ラベルシート巻取り軸と枠部巻取り軸とにそれぞれ結合した二個の従動プーリと、それら駆動プーリと二個の従動プーリとに巻き掛けた共通の環状ベルトとを有するベルト伝動機構であると好ましい。 In the sheet winding device of the present invention, the transmission mechanism includes a drive pulley coupled to the output shaft of the motor, and two followers coupled to the label sheet winding shaft and the frame portion winding shaft, respectively. A belt transmission mechanism having a pulley and a common annular belt wound around the drive pulley and the two driven pulleys is preferable.

このように伝動機構を構成すれば、安価な構成で、単一のモータの出力軸の回転をラベルシート巻取り軸と枠部巻取り軸とに伝動でき、しかも枠部巻取り軸に結合した従動プーリに容易に機械式摩擦クラッチを設けることができる。 If the transmission mechanism is configured in this way, the rotation of the output shaft of a single motor can be transmitted to the label sheet winding shaft and the frame winding shaft with an inexpensive structure, and further, the rotation can be coupled to the frame winding shaft. A mechanical friction clutch can be easily provided on the driven pulley.

さらに、この発明のシート巻取り装置においては、前記ラベルシートの供給方向に関して前記二本の分離ローラの上流側に巻取り緩み防止機構を具え、この巻取り緩み防止機構は、前記ラベルシートを交互に巻回される、上方の固定位置に位置するフリ−ローラおよびそのフリーローラよりも下方に位置するダンサーローラと、そのダンサーローラを上下方向揺動可能に支持する支持フレームとを有すると好ましい。 Further, in the sheet winding device of the present invention, a winding slack preventing mechanism is provided on the upstream side of the two separating rollers in the supply direction of the label sheet, and the winding slack preventing mechanism alternates the label sheets. It is preferable to have a free roller positioned at a fixed position above and a dancer roller positioned below the free roller, and a support frame that supports the dancer roller so as to be vertically swingable.

このように巻取り緩み防止機構を構成すれば、フリ−ローラとダンサーローラとに巻回されたラベルシートに、ダンサーローラおよび支持フレームの自重によってダンサーローラが張力を与えて、そのラベルシートを二本の分離ローラの間に供給するので、二本の分離ローラがラベルシートを挟持しつつラベルシート巻取り軸と枠部巻取り軸との巻取り速度に同期して駆動回転されなくても、ラベルシート巻取り軸に巻き取るラベルシートと枠部巻取り軸に巻き取る枠部との巻取り緩みを防止することができる。 If the winding and loosening prevention mechanism is configured in this way, the dancer roller applies tension to the label sheet wound around the free roller and the dancer roller by the weight of the dancer roller and the supporting frame, and the label sheet is unwound. Since it is supplied between the separation rollers of the book, even if the two separation rollers sandwich the label sheet and are not driven and rotated in synchronization with the winding speed of the label sheet winding shaft and the frame portion winding shaft, It is possible to prevent the label sheet wound on the label sheet winding shaft and the frame portion wound on the frame portion winding shaft from being loosened.

そして前記巻取り緩み防止機構は、前記支持フレームの上方揺動により前記ラベルシートの残り不足を検出して前記モータへの給電を停止する巻取り過ぎ防止スイッチを有していると好ましい。 Further, it is preferable that the winding looseness prevention mechanism includes an overwinding prevention switch that detects a shortage of the remaining label sheet by the upward swing of the support frame and stops power supply to the motor.

このように巻取り緩み防止機構を構成すれば、巻取り緩みと同時に巻取り過ぎも簡易な構成で防止することができ、特に、細い枠部の巻取り過ぎによる不測の切断を有効に防止することができる。 If the winding-loosening prevention mechanism is configured in this way, it is possible to prevent overwinding at the same time as the winding-loosening with a simple structure, and in particular, effectively prevent accidental cutting due to overwinding of the thin frame portion. be able to.

図４（ａ）および図４（ｂ）は、この実施形態のシート巻取り装置の機械式摩擦クラッチ１６を構成する第２の従動プーリ１５および滑り部材１５ｅをそれぞれ示す端面図であり、図示のように機械式摩擦クラッチ１６は、回転部材としての第２の従動プーリ１５にその軸線方向の全長に亘って延在するとともに半径方向に延在する切れ目１５ａを形成し、その従動プーリ１５を弾性的に拡縮径可能にするとともに、第２の従動プーリ１５の小径のハブ部分に切れ目１５ａと交差するねじ孔１５ｂを設けてそのねじ孔１５ｂ内にねじ部材としてのボルト１５ｃを螺合させ、さらに第２の従動プーリ１５の中心孔内に、概略円筒状に形成するとともにその軸線方向の全長に亘って切れ目１５ｄを形成して弾性的に拡縮径可能とした、例えばジュラコン等の比較的摩擦係数の低い樹脂材料からなる滑り部材１５ｅを配置して、その滑り部材１５ｅを第２の従動プーリ１５の中心孔の内周面と枠部巻取り軸９の後端部の外周面との間に介在させ、ボルト１５ｃを締め込むことによってその切れ目１５ａ，１５ｄを縮小させて第２の従動プーリ１５と滑り部材１５ｅとを縮径させ、第２の従動プーリ１５と枠部巻取り軸９との間、具体的には第２の従動プーリ１５内の滑り部材１５ｅの内周面と枠部巻取り軸９の外周面との間の滑り締結力を強める一方、ボルト１５ｃを緩めることによってその切れ目１５ａ，１５ｄを拡大させて第２の従動プーリ１５と滑り部材１５ｅとを拡径させ、上記の第２の従動プーリ１５と枠部巻取り軸９との間の滑り締結力を弱めることで、その滑り締結力を調節可能に構成されている。 FIG. 4A and FIG. 4B are end views showing the second driven pulley 15 and the sliding member 15e, which constitute the mechanical friction clutch 16 of the sheet winding device of this embodiment, respectively. As described above, the mechanical friction clutch 16 has the second driven pulley 15 serving as a rotating member, which has a slit 15a extending in the axial direction and extending in the radial direction, and the driven pulley 15 is elastic. The second driven pulley 15 has a small-diameter hub portion provided with a screw hole 15b intersecting the cut 15a, and a bolt 15c as a screw member is screwed into the screw hole 15b. In the center hole of the second driven pulley 15, a substantially cylindrical shape is formed, and a cut 15d is formed over the entire length in the axial direction of the second driven pulley 15 so that the diameter can be elastically expanded/contracted. A sliding member 15e made of a resin material having a low degree of elasticity is arranged, and the sliding member 15e is placed between the inner peripheral surface of the center hole of the second driven pulley 15 and the outer peripheral surface of the rear end of the frame portion winding shaft 9. By interposing and tightening the bolt 15c, the cuts 15a and 15d are reduced to reduce the diameters of the second driven pulley 15 and the sliding member 15e, and the second driven pulley 15 and the frame portion winding shaft 9 are connected. In the meantime, specifically, the slip fastening force between the inner peripheral surface of the sliding member 15e in the second driven pulley 15 and the outer peripheral surface of the frame portion winding shaft 9 is strengthened, while the bolt 15c is loosened to break the gap. By expanding 15a and 15d to expand the diameter of the second driven pulley 15 and the sliding member 15e, and weakening the slip fastening force between the second driven pulley 15 and the frame portion winding shaft 9 described above, The slip fastening force is adjustable.

また、第１の従動プーリ１４と駆動プーリ１７とは互いに同一の外径を有する一方で、第２の従動プーリ１５は第１の従動プーリ１４および駆動プーリ１７よりも小さい外径を有しており、これにより、第１の従動プーリ１４およびそこに固定結合したラベルシート巻取り軸８はＡＣモータ１０の出力軸１０ａと等速で回転駆動されるのに対し、第２の従動プーリ１５はＡＣモータ１０の出力軸１０ａおよびラベルシート巻取り軸８よりもある程度、例えば１．２倍程度高速度で回転駆動され、その第２の従動プーリ１５に駆動結合した枠部巻取り軸９は、第２の従動プーリ１５に設けられた機械式摩擦クラッチ１６の、ボルト１５ｃの締め込み量の調節に基づく滑り締結によって回転速度を第２の従動プーリ１５よりも適宜減速されて、後述するラベルシートＳ’の巻取り速度に対応した巻取り速度で枠部Ｆを巻き取るように回転駆動される。 Further, the first driven pulley 14 and the drive pulley 17 have the same outer diameter as each other, while the second driven pulley 15 has a smaller outer diameter than the first driven pulley 14 and the drive pulley 17. As a result, the first driven pulley 14 and the label sheet winding shaft 8 fixedly coupled thereto are rotationally driven at a constant speed with the output shaft 10a of the AC motor 10, whereas the second driven pulley 15 is driven. The frame part take-up shaft 9 which is rotationally driven at a speed higher than the output shaft 10a of the AC motor 10 and the label sheet take-up shaft 8 to some extent, for example, about 1.2 times, and drivingly coupled to the second driven pulley 15 thereof, The rotational speed of the mechanical friction clutch 16 provided on the second driven pulley 15 is appropriately reduced as compared with that of the second driven pulley 15 by slip engagement based on the adjustment of the tightening amount of the bolt 15c. The frame part F is rotationally driven at a winding speed corresponding to the winding speed of S′.

さらに、ラベルシート巻取り軸８上には、ラベルシートＳ’を巻き付けるための例えば紙筒からなる巻芯Ｃ１を外周面上に嵌挿される短い円筒状のスペーサ２１が軸線方向位置調節可能に挿通されてラベルシート巻取り軸８と一体回転するように固定ねじで固定されるとともに、その巻芯Ｃ１の両端に当接して巻芯Ｃ１を間に挟みラベルシート巻取り軸８と一体回転させる二枚のフランジ２２も軸線方向位置調節可能に挿通されて各々固定ねじ（図２，図３では蝶ねじ）で固定されており、後述の如くして巻芯Ｃ１上にラベルシートＳ’を巻き付けた後、手前側のフランジ２２の固定ねじを緩めてそのフランジ２２をラベルシート巻取り軸８上から抜き出すことで、ラベルシートＳ’を巻き付けた巻芯Ｃ１をスペーサ２１上から取り出すことができる。 Further, on the label sheet winding shaft 8, a short cylindrical spacer 21 into which a core C1 made of, for example, a paper cylinder for winding the label sheet S'is fitted on the outer peripheral surface is axially positionally adjustable. The label sheet take-up shaft 8 is rotated integrally with the label sheet take-up shaft 8 and is fixed to the label sheet take-up shaft 8 by abutting both ends of the core C1 so as to rotate integrally with the label sheet take-up shaft 8. The two flanges 22 are also inserted so that the position in the axial direction can be adjusted, and are fixed by fixing screws (thickness screws in FIGS. 2 and 3) respectively, and the label sheet S′ is wound around the winding core C1 as described later. After that, by loosening the fixing screw of the flange 22 on the front side and pulling out the flange 22 from the label sheet winding shaft 8, the core C1 around which the label sheet S′ is wound can be taken out from the spacer 21.

一方、枠部巻取り軸９上には、枠部Ｆを巻きつけるための例えば紙筒からなる巻芯Ｃ２を外周面上に嵌挿される概略Ｃ字状断面の中間筒２３をそのＣ字の切れ目をキー２４ａで僅かに拡げて拡径した状態で嵌着された巻取りロール２４が枠部巻取り軸９と一体回転するようにねじで固定されており、後述の如くして巻芯Ｃ２上に枠部Ｆを巻き付けた後、中間筒２３を巻取りロール２４上から軸線方向に抜き出すことで、中間筒２３の切れ目からキー２４ａが外れて中間筒２３が縮径し、枠部Ｆをきつく巻き付けた巻芯Ｃ２から中間筒２３を容易に抜き出すことができる。 On the other hand, on the frame part winding shaft 9, an intermediate cylinder 23 having a substantially C-shaped cross section, into which a winding core C2 for winding the frame part F, which is made of, for example, a paper cylinder, is fitted on the outer peripheral surface, is formed. The winding roll 24 fitted in a state where the cut is slightly expanded by the key 24a and expanded in diameter is fixed by a screw so as to rotate integrally with the frame winding shaft 9, and the core C2 will be described later. After winding the frame portion F on the upper side, by pulling out the intermediate cylinder 23 from the winding roll 24 in the axial direction, the key 24a is removed from the cut of the intermediate cylinder 23, the intermediate cylinder 23 is reduced in diameter, and the frame portion F is removed. The intermediate cylinder 23 can be easily pulled out from the tightly wound core C2.

A fixed support arm 25 having a proximal end portion fixed and protruding to the side of the housing 3, and two support shafts 26 cantilevered by the fixed support arm 25 are rotatably supported respectively. A free roller 27 (not shown in FIGS. 2 and 3), and a side portion (right side in FIG. 1) of the front panel 3a of the housing 3 on the same side as the side supporting the fixed support arm 25. Part) and the front support plate 5 extend horizontally in the front-back direction of the main body 1 (direction orthogonal to the paper surface in FIG. 1), and both ends thereof are connected to the front panel 3a of the housing 3 and the front part. A base end portion is cantilevered by a swing shaft 28 rotatably supported by a support plate 5 so as to extend parallel to each other, and to vertically swing about the axis of the swing shaft 28 of the housing 3. Two free support rollers 27 are rotatably supported by two swing support frames 29 protruding laterally and three support shafts 30 having both ends fixed to the swing support frames 29. On the other hand, it has three dancer rollers 31 (not shown in FIGS. 2 and 3) which are alternately arranged when viewed from above, and these two free rollers 27 and two swings. The support frame 29 and the three dancer rollers 31 form a winding looseness prevention mechanism 32.

この巻取り緩み防止機構３２は、図１に示すように、分離ローラ６，７より上流側でラベルプリンタＬＰから送り出された、枠部Ｆの分離前のラベルシートＳを三本のダンサーローラ３１と二本のフリーローラ２７とに交互に巻き掛けると、二本の揺動支持フレーム２９と三本の支持軸３０と三本のダンサーローラ３１との自重で適切な張力を付加した所定量のラベルシートＳをそれらダンサーローラ３１とフリーローラ２７とで保持しつつ、そのラベルシートＳを二本の分離ローラ６，７間に供給する。 As shown in FIG. 1, the winding slack prevention mechanism 32 includes three dancer rollers 31 for the label sheet S before separation of the frame portion F, which is fed from the label printer LP on the upstream side of the separation rollers 6, 7. And two free rollers 27 are alternately wound around each other, the two swing support frames 29, the three support shafts 30, and the three dancer rollers 31 have a predetermined amount of a proper tension applied by their own weight. While holding the label sheet S by the dancer roller 31 and the free roller 27, the label sheet S is supplied between the two separating rollers 6 and 7.

ここで、揺動軸２８の後端部は筐体３の前面パネル３ａを貫通して筐体３内に突出し、その揺動軸２８の後端部には円盤状の偏心カム部材３３が固定されており、筐体３内には揺動軸２８に対して偏心した偏心カム部材３３の外周面に作動腕を摺接させた、例えば通常のマイクロスイッチからなる巻取り過ぎ防止スイッチ３４が設けられ、この巻取り過ぎ防止スイッチ３４は、電源スイッチ１ｂと回転方向切替スイッチ１ｅとの間の電源配線に介挿されていて、例えばラベルプリンタＬＰの作動等により上記ダンサーローラ３１とフリーローラ２７とによるラベルシートＳの保持量が所定量あって揺動支持フレーム２９が例えば水平等の所定角度まで下がっていると、偏心カム部材３３の外周面により作動腕を押し下げられてＯＮ状態を維持し、ＡＣモータ１０への給電を継続してＡＣモータ１０を動作させる一方、例えばラベルプリンタＬＰの停止等により上記ダンサーローラ３１とフリーローラ２７とによるラベルシートＳの保持量が所定量より少なくなって揺動支持フレーム２９が所定以上の傾斜角度で持ち上がると、偏心カム部材３３の外周面により作動腕が押し下げられなくなってＯＦＦ状態になり、ＡＣモータ１０への給電を停止してＡＣモータ１０の動作を停止させる。 Here, the rear end of the swing shaft 28 penetrates the front panel 3a of the housing 3 and projects into the housing 3, and a disc-shaped eccentric cam member 33 is fixed to the rear end of the swing shaft 28. The housing 3 is provided with an overwinding prevention switch 34, which is, for example, a normal microswitch, in which an operating arm is slidably contacted with an outer peripheral surface of an eccentric cam member 33 that is eccentric with respect to the swing shaft 28. The overwinding prevention switch 34 is inserted in the power wiring between the power switch 1b and the rotation direction changeover switch 1e, and the dancer roller 31 and the free roller 27 are connected to each other by, for example, the operation of the label printer LP. When the swinging support frame 29 is lowered to a predetermined angle such as horizontal by a predetermined amount of holding the label sheet S by, the operating arm is pushed down by the outer peripheral surface of the eccentric cam member 33 to maintain the ON state, While the power supply to the AC motor 10 is continued and the AC motor 10 is operated, the holding amount of the label sheet S by the dancer roller 31 and the free roller 27 becomes smaller than a predetermined amount due to, for example, the stop of the label printer LP, and shakes. When the dynamic support frame 29 is lifted at an inclination angle of a predetermined value or more, the outer peripheral surface of the eccentric cam member 33 prevents the operating arm from being pushed down to be in the OFF state, and the power supply to the AC motor 10 is stopped to operate the AC motor 10. Stop.

この実施形態のシート巻取り装置Ｒはさらに、筐体３の前面パネル３ａの、二本の分離ローラ６，７を支持する側と同じ側の側部（図１では右側部）の、それら二本の分離ローラ６，７の上方の位置に基端部を揺動可能に支持された揺動支持腕３５と、その揺動支持腕３５の先端部に基端部を片持ち支持された支持軸３６と、その支持軸３６に回転自在に支持されて揺動支持腕３５の枠部巻取り軸９寄りの側端よりも外側に外周面を突出させた押えローラ３７とを有しており、この押えローラ３７は、その押えローラ３７と揺動支持腕３５と支持軸３６との自重により枠部巻取り軸９側に傾動して、巻芯Ｃ２上に巻き付けられた枠部Ｆを押さえ付け、枠部Ｆの緩みを防止することができる。 The sheet winding device R of this embodiment further includes a front panel 3a of the housing 3 on the same side as the side supporting the two separation rollers 6 and 7 (right side in FIG. 1). A swing support arm 35 whose base end is swingably supported above the separation rollers 6 and 7 of the book, and a support in which the base end is cantilevered at the tip of the swing support arm 35. It has a shaft 36 and a pressing roller 37 rotatably supported by the support shaft 36 and having an outer peripheral surface protruding outward from the side end of the swing support arm 35 near the frame portion winding shaft 9. The pressing roller 37 is tilted toward the frame part winding shaft 9 side by its own weight of the pressing roller 37, the swing support arm 35, and the support shaft 36, and presses the frame part F wound on the winding core C2. It is possible to prevent the frame part F from being loosened.

かかる実施形態のシート巻取り装置Ｒにあっては、図１，２に示すように、先ず、ラベルプリンタＬＰから送り出された、ラベルＬを印刷済みで枠部Ｆを分離する前のラベルシートＳを、三本のダンサーローラ３１と二本のフリーローラ２７とに交互に巻き掛けてある程度の長さ分保持した後、二本の分離ローラ６，７間に供給し、二本の分離ローラ６，７間を通したラベルシートＳの剥離シートＰ上から枠部Ｆを剥がして、その枠部Ｆの先端部を、枠部巻取り軸９上の巻取りロール２４に嵌挿された巻芯Ｃ２上に、例えばその枠部Ｆの粘着剤によって固着する一方、剥離シートＰ上にラベルＬだけが残ったラベルシートＳ’の先端部を、ラベルシート巻取り軸８上のスペーサ２１に嵌挿した巻芯Ｃ１上に、例えば粘着テープ等で固着する。 In the sheet winding device R of such an embodiment, as shown in FIGS. 1 and 2, first, the label sheet S sent from the label printer LP has been printed with the label L and before the frame portion F is separated. Are alternately wound around the three dancer rollers 31 and the two free rollers 27 and held for a certain length, and then supplied between the two separation rollers 6 and 7, and the two separation rollers 6 The core portion F is peeled off from the release sheet P of the label sheet S that has passed between the first and the second label sheets 7, and the tip end portion of the frame portion F is fitted and inserted into the winding roll 24 on the frame portion winding shaft 9. The leading end of the label sheet S′ on which the label L only remains on the release sheet P is fitted into the spacer 21 on the label sheet winding shaft 8 while being fixed onto the C2 by, for example, the adhesive of the frame portion F. It is fixed to the wound core C1 with, for example, an adhesive tape.

次いで、電源スイッチ１ｂおよび回転方向切替スイッチ１ｅの操作によりＡＣモータ１０を正転させると、ＡＣモータ１０の出力軸１０ａと等速でラベルシート巻取り軸８が回転してラベルシートＳ’を巻芯Ｃ１上に巻き取ってゆき、それと同時に、ＡＣモータ１０の出力軸１０ａよりも高速度で回転駆動される第２の従動プーリ１５に駆動結合した枠部巻取り軸９が、機械式摩擦クラッチ１６の滑り締結によって回転速度を第２の従動プーリ１５よりも適宜減速されて、枠部ＦやラベルシートＳ’の巻取りの進行に伴って増大する巻取り径の相違にかかわらず、ラベルシート巻取り軸８によるラベルシートＳ’の巻取り速度に対応した速度でラベルシートＳ上から枠部Ｆを上側の分離ローラ７の外周面に沿わせて連続的に引き剥がしながらその枠部Ｆを巻芯Ｃ２上に巻き取ってゆく。この巻取りの際、枠部Ｆに加わる張力が大き過ぎると枠部Ｆが切れる可能性があるので、枠部Ｆが切れないように機械式摩擦クラッチ１６のボルト１５ｃの締め込み量を適宜調節しておく。 Next, when the AC motor 10 is rotated in the forward direction by operating the power switch 1b and the rotation direction changeover switch 1e, the label sheet winding shaft 8 rotates at the same speed as the output shaft 10a of the AC motor 10 to wind the label sheet S'. The frame portion winding shaft 9 is wound on the core C1 and, at the same time, the frame portion winding shaft 9 drivingly coupled to the second driven pulley 15 which is rotationally driven at a higher speed than the output shaft 10a of the AC motor 10 has a mechanical friction clutch. The rotational speed of the label sheet is appropriately reduced from that of the second driven pulley 15 by the slip-fastening of 16, and the label sheet is increased regardless of the difference in the winding diameter that increases as the winding of the frame portion F or the label sheet S′ progresses. While continuously peeling the frame portion F along the outer peripheral surface of the upper separation roller 7 from the label sheet S at a speed corresponding to the winding speed of the label sheet S′ by the winding shaft 8, the frame portion F is removed. Take it up on the core C2. During this winding, if the tension applied to the frame portion F is too large, the frame portion F may be broken. Therefore, the tightening amount of the bolt 15c of the mechanical friction clutch 16 is appropriately adjusted so that the frame portion F is not broken. I'll do it.

ラベルプリンタＬＰがインクノズルの洗浄等のためにラベルシートＳの送り出しを中断してラベルシートＳを少し引き戻した場合には、ダンサーローラ３１とフリーローラ２７とによるラベルシートＳの保持量が減るも支持フレーム２９がさほど上がらないので、ラベルシートＳへの張力に影響を与えずに巻取り動作を継続してラベルシートＳ’および枠部Ｆの巻取り緩みを防止し、その一方、ラベルシートＳの送り出しの中断が長くなり、ラベルシートＳの保持量が大幅に減って支持フレーム２９が所定角度まで上がると、ＡＣモータ１０が自動的に動作を停止してラベルシートＳ’および枠部Ｆの巻取りを中断し、ラベルプリンタＬＰがラベルシートＳの送り出しを再開すると、ダンサーローラ３１とフリーローラ２７とによるラベルシートＳの保持量が戻って、ＡＣモータ１０は自動的にラベルシートＳ’および枠部Ｆの巻取りを再開する。 When the label printer LP interrupts the feeding of the label sheet S for cleaning the ink nozzles and pulls the label sheet S back a little, the holding amount of the label sheet S by the dancer roller 31 and the free roller 27 is reduced. Since the support frame 29 does not rise so much, the winding operation is continued without affecting the tension on the label sheet S to prevent the label sheet S′ and the frame portion F from being loosely wound, while the label sheet S is When the feeding amount of the label sheet S is lengthened and the holding amount of the label sheet S is significantly reduced to raise the support frame 29 to a predetermined angle, the AC motor 10 automatically stops its operation and the label sheet S′ and the frame portion F are stopped. When the winding of the label is stopped and the label printer LP restarts the feeding of the label sheet S, the holding amount of the label sheet S by the dancer roller 31 and the free roller 27 returns, and the AC motor 10 automatically transfers the label sheet S′ and the label sheet S′. The winding of the frame portion F is restarted.

そしてラベルプリンタＬＰが印刷済みのラベルシートＳの送り出しを終了すると、送り出しの中断時と同様に、ダンサーローラ３１とフリーローラ２７とによるラベルシートＳの保持量が減り、ＡＣモータ１０が自動的に動作を停止してラベルシートＳ’および枠部Ｆの巻取りを終了する。その後は、ラベルシートＳ’の尾端部を緩まないように引っ張った状態で巻芯Ｃ１上のラベルシートＳ’に粘着テープあるいは剥がしたラベルＬ等で固定するとともに、粘着剤付きの枠部Ｆの尾端部もその尾端部の粘着剤で巻芯Ｃ２上の枠部Ｆに固定し、次いで、ラベルシート巻取り軸８上からフランジ２２を抜き取ってラベルシートＳ’を巻き取った巻芯Ｃ１をスペーサ２１から抜き出すとともに、枠部巻取り軸９上の巻取りロール２４から枠部Ｆを巻き取った巻芯Ｃ２をその内側の中間筒２３とともに抜き取り、さらに、巻取りロール２４からの抜き取りで縮径した中間筒２３を巻芯Ｃ２から抜き出して、巻取り作業を終了する。 When the label printer LP finishes feeding the printed label sheet S, the holding amount of the label sheet S by the dancer roller 31 and the free roller 27 is reduced, and the AC motor 10 is automatically operated, as in the case of the interruption of the feeding. The operation is stopped and the winding of the label sheet S′ and the frame portion F is completed. After that, the tail end portion of the label sheet S′ is pulled so as not to loosen and fixed to the label sheet S′ on the winding core C1 with an adhesive tape or a peeled label L, and the frame portion F with an adhesive agent is attached. The tail end of the label core is fixed to the frame part F on the core C2 with the adhesive of the tail end, and then the flange 22 is pulled out from the label sheet winding shaft 8 to wind the label sheet S'. C1 is pulled out from the spacer 21, and the core C2 wound around the frame F from the winding roll 24 on the frame winding shaft 9 is pulled out together with the intermediate cylinder 23 inside thereof, and further pulled out from the winding roll 24. The intermediate cylinder 23 having a reduced diameter is extracted from the winding core C2, and the winding operation is completed.

従って、この実施形態のシート巻取り装置Ｒによれば、単一のＡＣモータ１０でラベルシート巻取り軸８と枠部巻取り軸９とを一緒に回転駆動し、しかも滑り締結状態の機械式摩擦クラッチ１６による伝動で、枠部巻取り軸９による枠部Ｆの巻取り速度を、枠部ＦやラベルシートＳ’の増大する巻取り径の相違にかかわらず、ラベルシート巻取り軸８によるラベルシートＳ’の巻取り速度に対応させるので、ラベルシートＳの剥離シートＰから粘着剤付きのラベルＬの周囲の連続的な梯子状の枠部Ｆだけを剥がして分離させ、粘着剤付きのラベルＬを剥離シートＰ上に付着したまま残した帯状のラベルシートＳ’と、粘着剤付きの枠部Ｆとを別途に巻き取るシート巻取り装置Ｒを、簡易且つ安価に構成することができる。 Therefore, according to the sheet winding device R of this embodiment, the label sheet winding shaft 8 and the frame portion winding shaft 9 are rotationally driven together by the single AC motor 10, and the mechanical type in the slip-fastened state is used. By the transmission by the friction clutch 16, the winding speed of the frame portion F by the frame winding shaft 9 is set by the label sheet winding shaft 8 regardless of the difference in the winding diameters of the frame portion F and the label sheet S′. Since it corresponds to the winding speed of the label sheet S′, only the continuous ladder-shaped frame portion F around the label L with the adhesive is peeled off from the release sheet P of the label sheet S and separated. It is possible to easily and inexpensively configure the sheet winding device R that separately winds the strip-shaped label sheet S′ in which the label L remains attached on the release sheet P and the frame portion F with the adhesive. ..

図５（ａ），図５（ｂ）および図５（ｃ）は、この発明のシート巻取り装置の他の一実施形態の要部を示す正面図、平面図および側面図であり、この実施形態のシート巻取り装置は、剥離シートＰ上からの枠部Ｆの引き剥がし時にラベルＬが一緒に剥がれるのを防止する櫛形部材３８を設けた点のみが先の実施形態と異なり、他の構成は先の実施形態と同様であるので、ここでは主にその櫛形部材３８を設けた点を説明する。 5(a), 5(b) and 5(c) are a front view, a plan view and a side view showing a main part of another embodiment of the sheet winding device of the present invention. The sheet winding device of the embodiment is different from the previous embodiment only in that a comb-shaped member 38 is provided to prevent the label L from being peeled off together when the frame portion F is peeled off from the release sheet P, and other configurations. Since it is the same as that of the previous embodiment, the point where the comb-shaped member 38 is provided will be mainly described here.

すなわち、この実施形態のシート巻取り装置は、図示例では透明な、例えばアクリル等の弾性変形可能な樹脂製の長方形の板材からなり、一方の長辺側の側部に櫛歯状の突起３８ａを多数形成した櫛形部材３８を二本の分離ローラ６，７の間に、突起３８ａの先端が上側の分離ローラ７の外周面よりもラベルシートＳの送り方向で下流側に多少突出するように挿入配置して、その櫛形部材３８の他方の長辺側の側部を支持棒３９に固定し、その支持棒３９を筐体３の前面パネル３ａに固定支持する一方、その櫛歯状の突起３８ａに対応する多数の浅い周方向溝７ａを上側の分離ローラ７の外周面に形成したものである。 That is, the sheet winding device of this embodiment is made of a transparent rectangular plate material made of a resin such as acrylic which is transparent in the illustrated example, and has comb-shaped projections 38a on one long side. A plurality of comb-shaped members 38 are formed between the two separating rollers 6 and 7 so that the tips of the protrusions 38a slightly project to the downstream side of the outer peripheral surface of the upper separating roller 7 in the feeding direction of the label sheet S. The comb-shaped member 38 is inserted and fixed, and the other long side of the comb-shaped member 38 is fixed to the supporting rod 39, and the supporting rod 39 is fixedly supported by the front panel 3a of the housing 3, while the comb-shaped protrusion is formed. A large number of shallow circumferential grooves 7a corresponding to 38a are formed on the outer peripheral surface of the upper separation roller 7.

かかる実施形態のシート巻取り装置によれば、先の実施形態と同様の作用効果を奏するのに加えて、粘着剤付きの枠部Ｆを剥離シートＰ上から引き剥がして帯状のラベルシートＳ’をラベルシート巻取り軸８上に巻き取るとともに連続的な梯子状の枠部Ｆを枠部巻取り軸９上に巻き取る際に、ラベルシートＳ上のラベル用紙のラベルＬと枠部Ｆとの粘着剤が先のハーフカット時に充分に切断されていなかったり切断後に再度粘着してしまったりしていて、枠部Ｆと一緒にラベルＬも剥離シートＰ上から剥がされるのを、櫛形部材３８の櫛歯状の突起３８ａでラベルＬを剥離シートＰ上に押え付けて防止することができる。 According to the sheet winding device of such an embodiment, in addition to the same effect as that of the previous embodiment, the frame portion F with the adhesive is peeled off from the release sheet P and the strip-shaped label sheet S′. When the continuous ladder-shaped frame portion F is wound on the label sheet winding shaft 8 and the continuous ladder frame portion F is wound on the frame portion winding shaft 9, the label L and the frame portion F of the label sheet on the label sheet S are When the adhesive of No. 2 is not sufficiently cut at the time of the previous half-cutting, or has adhered again after cutting, the label L is peeled off from the release sheet P together with the frame F. The label L can be pressed against the release sheet P and prevented by the comb-teeth-shaped protrusions 38a.

ところで、枠部Ｆには、ラベルシートＳ’の長手方向および幅方向にそれぞれ連続している部分があるが、それらの連続部分が何れかの突起３８ａに掛かる場合には、突起３８ａは枠部Ｆの連続部分で上方に押されて弾性的に反り上がり、分離ローラ７の周方向溝７ａ内に退避してその連続部分を逃がすので、突起３８ａからの過度の張力で枠部Ｆが切断されるのを防止することができる。また、必要に応じて上下の分離ローラ６，７の間隔を狭めたりそれらの分離ローラ６，７でラベルシートＳを挟持して送ったりする場合にも、櫛形部材３８の突起３８ａを分離ローラ７の周方向溝７ａ内に退避させることができる。なお、櫛形部材３８の突起３８ａがラベルＬを押え付けるとともに枠部Ｆの連続部分を逃がすのに適した低い弾性力を有している場合には、分離ローラ７の周方向溝７ａを省略することもできる。 By the way, the frame portion F has portions that are continuous in the longitudinal direction and the width direction of the label sheet S′, but if these continuous portions hang on any of the protrusions 38 a, the protrusion 38 a will be Since the continuous portion of F pushes upward and elastically warps, it retracts into the circumferential groove 7a of the separation roller 7 and escapes the continuous portion, so that the frame portion F is cut by excessive tension from the protrusion 38a. Can be prevented. Further, when the spacing between the upper and lower separating rollers 6 and 7 is narrowed or the label sheet S is sandwiched and fed by the separating rollers 6 and 7, the protrusion 38a of the comb-shaped member 38 can be separated from the separating roller 7 when necessary. Can be retracted into the circumferential groove 7a. When the protrusion 38a of the comb-shaped member 38 has a low elastic force suitable for pressing the label L and releasing the continuous portion of the frame portion F, the circumferential groove 7a of the separation roller 7 is omitted.

以上、図示の実施形態に基づき説明したが、この発明は上述の実施形態に限定されるものでなく、特許請求の範囲の記載範囲内で適宜変更し得るものであり、例えばモータは、単相交流モータでなく三相交流モータや直流モータとしても良く、また伝動機構は、ベルト伝動機構でなく歯車伝動機構あるいはベルト伝動機構と歯車伝動機構との組合せとしても良い。 Although the present invention has been described above based on the illustrated embodiment, the present invention is not limited to the above-described embodiment and can be appropriately modified within the scope of the claims. A three-phase AC motor or a DC motor may be used instead of the AC motor, and the transmission mechanism may be a gear transmission mechanism or a combination of a belt transmission mechanism and a gear transmission mechanism instead of the belt transmission mechanism.

そして参考例として、機械式摩擦クラッチは、枠部巻取り軸の外周面と第２の従動プーリ内の滑り部材の内周面との間の滑り締結でなく、例えばワッシャ状の二枚の滑り部材で第２の従動プーリの両端面を挟み、枠部巻取り軸に設けたフランジとその枠部巻取り軸の軸端部に螺合させたナットとでさらにそれら二枚の滑り部材と第２の従動プーリとを軸線方向に挟んで、そのナットを締め込んだり緩めたりして第２の従動プーリの挟持力を調節することで、滑り締結力を調節可能としても良い。
Then, as a reference example, the mechanical friction clutch is not a slip-engagement between the outer peripheral surface of the frame part winding shaft and the inner peripheral surface of the sliding member in the second driven pulley, but a slip of two washers, for example. Both end surfaces of the second driven pulley are sandwiched by a member, and a flange provided on the frame part winding shaft and a nut screwed to the shaft end part of the frame part winding shaft further provide the two sliding members and the first sliding member. The slip fastening force may be adjustable by sandwiching the second driven pulley in the axial direction and tightening or loosening the nut to adjust the sandwiching force of the second driven pulley.

かくしてこの発明のシート巻取り装置によれば、単一のモータでラベルシート巻取り軸と枠部巻取り軸とを一緒に回転駆動し、しかも滑り締結状態の機械式摩擦クラッチによる伝動で、枠部巻取り軸による枠部の巻取り速度を、枠部やラベルシートの増大する巻取り径の相違にかかわらず、ラベルシート巻取り軸によるラベルシートの巻取り速度に対応させるので、ラベルシートの剥離シートから粘着剤付きラベルの周囲の連続的な梯子状の枠部だけを剥がして分離させ、粘着剤付きラベルを剥離シート上に付着したまま残した帯状のラベルシートと粘着剤付き枠部とを別途に巻き取るシート巻取り装置を、簡易且つ安価に構成することができる。 Thus, according to the sheet winding device of the present invention, the label sheet winding shaft and the frame portion winding shaft are rotationally driven together by a single motor, and the frame friction is transmitted by the mechanical friction clutch in the slip-fastened state. Since the take-up speed of the frame portion by the partial take-up shaft is made to correspond to the take-up speed of the label sheet by the label sheet take-up shaft regardless of the difference in the take-up diameter of the frame portion or the label sheet, Only the continuous ladder-shaped frame around the label with adhesive is peeled off from the release sheet to separate it, and the strip-shaped label sheet and the frame with adhesive are left on the release sheet with the label with adhesive attached. The sheet winding device for separately winding the sheet can be configured easily and inexpensively.
