Description

本発明は、長尺の帯状の用紙を巻き取るための用紙巻取り機構に関する。   The present invention relates to a sheet winding mechanism for winding a long belt-shaped sheet.

長尺の帯状の用紙(例えばラベル剥離後のラベル台紙等)を巻き取るための用紙巻取り機構として種々のものが提案されている。
(i)特開平10−250885号公報に記載のものでは、台紙巻取部を周方向に分割された複数の円筒部材から構成して、各円筒部材の内面に小径部および大径部をそれぞれ形成し、操作部材が小径部に嵌合したときに各円筒部材を巻き取り径に保持して台紙の巻き取りを行うとともに、台紙の巻き取り後は、操作部材を各円筒部材の大径部に嵌合させて各円筒部材の巻き取り径を縮径させることにより、各円筒部材に巻き取られた台紙を各円筒部材の一端側から引き抜けるようにしている(同公報の段落[0043]〜[0044]、図1および図7参照)。
Various types of paper take-up mechanisms for taking up long strip-shaped paper (for example, a label mount after label peeling) have been proposed.
(I) In the one described in Japanese Patent Laid-Open No. 10-250885, the mount winding portion is composed of a plurality of cylindrical members divided in the circumferential direction, and a small diameter portion and a large diameter portion are respectively provided on the inner surface of each cylindrical member. When the operation member is fitted to the small diameter portion, each cylindrical member is held at the winding diameter to wind the mount, and after the mount is wound, the operation member is moved to the large diameter portion of each cylindrical member. The mount wound around each cylindrical member is pulled out from one end side of each cylindrical member by reducing the winding diameter of each cylindrical member (see paragraphs [0043] to [0044], see FIG. 1 and FIG.

(ii)特開2009−203029号公報に記載のものでは、巻き取り軸を、一端がフランジ部に固定された固定軸と、固定軸の外周側に対向配置された軸方向移動可能な一対の平板状の可動片とから構成し、各可動片の一端を固定軸の他端側に形成された大径の可動片支持部に係合させた状態で台紙の巻き取りを行うとともに、台紙の巻取り後は、各可動片をフランジ部側から軸方向に引っ張って各可動片の一端と固定軸の他端側の可動片支持部との係合状態を解除して巻き取り径を縮径させることにより、巻き取り軸に巻き取った台紙を巻き取り軸から取り外すようにしている(同公報の段落[0060]、[0062]〜[0064]、図6および図9参照)。 (Ii) In the thing of Unexamined-Japanese-Patent No. 2009-203029, a winding axis | shaft is made into a pair of axially-movable axially arranged oppositely to the fixed axis | shaft which one end was fixed to the flange part, and the outer peripheral side of the fixed axis The mount is wound up in a state where one end of each movable piece is engaged with a large-diameter movable piece support formed on the other end side of the fixed shaft. After winding, each movable piece is pulled in the axial direction from the flange side to release the engagement state between one end of each movable piece and the movable piece support on the other end of the fixed shaft, thereby reducing the winding diameter. By doing so, the mount wound around the take-up shaft is removed from the take-up shaft (see paragraphs [0060], [0062] to [0064], FIGS. 6 and 9).

(iii)特開昭63−165257号公報に記載のものでは、各々略半円筒状の一対の巻取コアを円筒状に組み付けて巻取部を構成し、巻取部の内部に軸方向に延びかつ一端に操作レバーを有するボス部を挿通させ、ボス部外周の複数のカム部を巻取コア内周の複数のカム圧接部にそれぞれ圧接させて巻取部を拡径させた状態で台紙の巻き取りを行うとともに、巻取り後は、操作レバーを操作してボス部外周の各カム部と巻取コア内周の各カム圧接部との圧接状態を解除して各巻取コアの巻き取り径を縮径させることにより、各巻取コアに巻き付けられた台紙を各巻取コアから取り外すようにしている(同公報の第2頁左上欄第19行〜同頁右上欄第8行、同頁左下欄第7〜12行、同頁同欄第19行〜同頁右下欄第3行、第3頁左上欄第5〜13行、第1図、第2図および第4図〜第7図参照)。 (Iii) In the one described in JP-A-63-165257, a pair of substantially semi-cylindrical winding cores are assembled into a cylindrical shape to constitute a winding portion, and the winding portion is axially arranged inside the winding portion. A base plate in a state where the boss portion extending and having an operation lever at one end is inserted, the plurality of cam portions on the outer periphery of the boss portion are respectively pressed against the plurality of cam pressure contact portions on the inner periphery of the winding core, and the winding portion is expanded in diameter. After winding, the operating lever is operated to release the pressure contact state between each cam part on the outer circumference of the boss and each cam pressure contact part on the inner circumference of the take-up core to take up each winding core. By reducing the diameter, the mount wound around each winding core is removed from each winding core (the second page, upper left column, line 19 to the upper right column of the same publication, the eighth line, the lower left page). Column 7th to 12th line, same page same column 19th line to same page lower right column 3rd line, third page upper left column 5th Three rows, Fig. 1, reference Figure 2 and Figure 4-Figure 7).

(iv)特開2010−1082号公報に記載のものでは、台紙巻取り軸を、基体と、これに接近離反自在な移動体とから構成し、台紙巻取り軸の内部に軸方向に延びかつ一端に操作ノブを有する押体を挿通させ、押体外周の複数のカムを移動体内周の複数のカムフォロアにそれぞれ圧接させ移動体を基体から離反させて台紙巻取り軸を拡径させた状態で台紙の巻き取りを行うとともに、巻取り後は、操作ノブを操作して押体外周の各カムと移動体内周の各カムフォロアとの圧接状態を解除し移動体を基体に接近させて台紙巻取り軸の巻き取り径を縮径させることにより、台紙巻取り軸に巻き付けられた台紙を台紙巻取り軸から取り外すようにしている(同公報の段落[0022]、[0023]、[0036]、[0045]、図4および図5参照)。 (Iv) In the one described in Japanese Patent Application Laid-Open No. 2010-1082, the mount winding shaft is composed of a base body and a movable body that is movable toward and away from the base, and extends axially into the mount winding shaft. In a state where a push body having an operation knob at one end is inserted, a plurality of cams on the outer periphery of the push body are pressed against a plurality of cam followers on the periphery of the movable body, and the movable body is separated from the base to expand the mount winding shaft. Winding the mount, and after winding, operate the operation knob to release the pressure contact state between the cams on the outer periphery of the pusher and the cam followers on the outer periphery of the moving body, and bring the moving body closer to the base to wind the mount The mount wound around the mount winding shaft is removed from the mount winding shaft by reducing the winding diameter of the shaft (paragraphs [0022], [0023], [0036], [ 0045], see FIG. 4 and FIG. See).

しかしながら、前掲(i)の特開平10−250885号公報に記載のものでは、台紙巻取部を構成する各円筒部材の巻き取り径が縮径されるのは、あくまで各円筒部材の一端側のみであり、他端側は縮径されない(すなわち、台紙の幅方向全体にわたって縮径されるのではない)。したがって、長尺の台紙が各円筒部材に厚く巻き付けられて相当の巻付圧が各円筒部材の外面に作用している状態では、とくに、縮径されていない台紙巻取部の他端側において台紙を引き出す際に大きな力を必要とし、その結果、巻取り後のロール状の台紙の取外しを簡単かつ速やかに行えない場合が生じる。   However, in the above-mentioned (i) disclosed in JP-A-10-250885, the winding diameter of each cylindrical member constituting the mount winding portion is reduced only at one end side of each cylindrical member. The other end side is not reduced in diameter (that is, not reduced in the entire width direction of the mount). Therefore, in a state where a long mount is wound thickly around each cylindrical member and a considerable winding pressure is applied to the outer surface of each cylindrical member, particularly at the other end side of the mount take-up portion that is not reduced in diameter. When pulling out the mount, a large force is required. As a result, there is a case where the roll-shaped mount after winding cannot be easily and quickly removed.

同様に、前掲(ii)の特開2009−203029号公報に記載のものにおいても、巻き取り軸の巻き取り径が縮径されるのは、あくまで各可動片の一端側のみであり、他端側は縮径されない(すなわち、台紙の幅方向全体にわたっては縮径されるのではない)。したがって、長尺の台紙が固定軸および各可動片に厚く巻き付けられて相当の巻付圧が各可動片の外面に作用している状態では、とくに、縮径されていない各可動片の他端側において台紙を引き出す際に大きな力を必要とし、その結果、巻取り後のロール状の台紙の取外しを簡単かつ速やかに行えない場合が生じる。   Similarly, in the above-mentioned (ii) disclosed in JP 2009-203029 A, the winding diameter of the winding shaft is reduced only to one end side of each movable piece, and the other end. The side is not reduced in diameter (that is, not reduced in the entire width direction of the mount). Therefore, in the state where a long mount is wound thickly around the fixed shaft and each movable piece and a considerable winding pressure is applied to the outer surface of each movable piece, the other end of each movable piece that is not reduced in diameter is particularly When pulling out the mount on the side, a large force is required. As a result, it may not be possible to easily and quickly remove the roll-shaped mount after winding.

また、前掲(iii)の特開昭63−165257号公報に記載のものでは、前掲(i)および(ii)のものとは異なり、台紙の幅方向全体にわたって巻き取り径を縮径することは一応可能ではあるが、縮径の操作の際には、巻取コア内周の各カム圧接部に強固に圧接して局所的に喰い込んだボス部外周の各カム部の圧接状態を操作レバーを回転操作することで解除する必要があり、その際、各巻取コアの外周面に巻き取られた長尺の台紙から当該外周面に相当の巻付圧が作用していることと相俟って、操作レバーの操作には非常に大きな力を必要とし、その結果、巻取り後のロール状の台紙の取外しを簡単かつ速やかに行えない場合が生じる。   In addition, in the above-mentioned (iii) disclosed in JP-A-63-165257, unlike the above-mentioned (i) and (ii), it is possible to reduce the winding diameter over the entire width direction of the mount. Although it is possible to reduce the diameter, the operating lever shows the pressure contact state of each cam part on the outer circumference of the boss part that is firmly pressed against each cam pressure contact part on the inner circumference of the winding core. It is necessary to release it by rotating it, and this is coupled with the fact that a considerable winding pressure is acting on the outer peripheral surface from the long mount wound around the outer peripheral surface of each winding core. Therefore, a very large force is required to operate the operation lever, and as a result, there is a case where the roll-shaped mount after winding cannot be easily and quickly removed.

前掲(iv)の特開2010−1082号公報に記載のものでは、同様に、前掲(i)および(ii)のものとは異なり、台紙の幅方向全体にわたって巻き取り径を縮径することは一応可能ではあるが、縮径の操作の際には、移動体内周の各カムフォロアに強固に圧接して局所的に喰い込んだ押体外周の各カムの圧接状態を操作ノブを引き出し操作することで解除する必要があり、その際、台紙巻取り軸の外周面に巻き取られた長尺の台紙から当該外周面に相当の巻付圧が作用していることと相俟って、操作ノブの操作には非常に大きな力を必要とし、その結果、巻取り後のロール状の台紙の取外しを簡単かつ速やかに行えない場合が生じる。   Similarly to the above-mentioned (iv) described in JP 2010-1082 A, unlike the above-mentioned (i) and (ii), it is possible to reduce the winding diameter over the entire width direction of the mount. Although it is possible to reduce the diameter, pull out the operation knob to pull out the pressure contact state of each cam on the outer periphery of the pusher that is firmly in contact with each cam follower on the periphery of the moving body. In this case, the operation knob is coupled with the fact that a considerable winding pressure is acting on the outer peripheral surface from the long mount wound on the outer peripheral surface of the mount winding shaft. In this operation, a very large force is required, and as a result, there is a case where the roll-shaped mount after winding cannot be easily and quickly removed.

本発明は、このような従来の実情に鑑みてなされたもので、本発明が解決しようとする課題は、長尺の帯状の用紙を巻き取った後のロール状用紙の取外しを簡単かつ速やかに行える用紙巻取り機構を提供することにある。また、本発明は、長尺の帯状の用紙の巻取り始端を簡単かつ確実に保持できる用紙巻取り機構を実現しようとしている。   The present invention has been made in view of such conventional circumstances, and the problem to be solved by the present invention is to easily and quickly remove a roll-shaped sheet after winding a long belt-shaped sheet. An object of the present invention is to provide a paper winding mechanism that can perform this. In addition, the present invention is intended to realize a paper winding mechanism that can easily and reliably hold the winding start end of a long belt-like sheet.

本発明に係る用紙巻取り機構は、長尺の帯状の用紙を巻き取るための機構であって、用紙が巻き付けられる外周面を有しかつ外周面の一部にポケット穴が形成された巻取り軸部と、ポケット穴に収容されるとともに、ポケット穴の外側に配置されかつ用紙の幅方向全体にわたって延在する外側面、および、ポケット穴の内側に配置されかつ軸方向にテーパ状に延びるテーパ状内側面を有し、ポケット穴からの外側面の突出量が変化するようにポケット穴内で半径方向に移動自在な内側テーパ部材と、内側テーパ部材のテーパ状内側面に対応しかつ係合し得るテーパ状外側面を有し、内側テーパ部材を半径方向に移動させるように軸方向に移動自在な外側テーパ部材とを備えている(請求項1参照)。   The paper winding mechanism according to the present invention is a mechanism for winding a long belt-like paper, and has a peripheral surface around which the paper is wound and has a pocket hole formed in a part of the peripheral surface. A shaft portion, an outer surface that is accommodated in the pocket hole, is disposed outside the pocket hole and extends over the entire width direction of the paper, and a taper that is disposed inside the pocket hole and extends in a taper shape in the axial direction. An inner tapered member that has a cylindrical inner surface and is radially movable within the pocket hole so that the amount of protrusion of the outer surface from the pocket hole changes, and corresponds to and engages with the tapered inner surface of the inner tapered member. An outer tapered member having a tapered outer surface to be obtained and movable in the axial direction so as to move the inner tapered member in a radial direction (see claim 1).

本発明によれば、用紙を巻取り軸部に巻き取る際には、内側テーパ部材が半径方向外方に移動して内側テーパ部材のポケット穴からの突出量が大きくなるように外側テーパ部材を軸方向に移動させた状態で、用紙を巻取り軸部の外周面および内側テーパ部材の外側面に巻き付ける一方、用紙の巻取り後は、内側テーパ部材が半径方向内方に移動して内側テーパ部材のポケット穴からの突出量が小さくなるように外側テーパ部材を軸方向に移動させることで、巻取り軸部の外周面および内側テーパ部材の外側面による巻き取り径を用紙の幅方向全体にわたって縮径させることができるので、巻取り軸部の外周面および内側テーパ部材の外側面に巻き取られた用紙を巻取り軸部から簡単に取り外すことができる。しかも、この場合には、外側テーパ部材が内側テーパ部材のテーパ状内側面に対応するテーパ状外側面を有していることで、外側テーパ部材のテーパ状外側面および内側テーパ部材のテーパ状内側面がそれぞれくさび面として面接触するので、内側テーパ部材の半径方向移動を比較的小さな力で行うことができ、これにより、巻取り軸部からの用紙の取外しを速やかに行うことができる。   According to the present invention, when the sheet is wound around the winding shaft portion, the outer tapered member is moved so that the inner tapered member moves radially outward and the amount of protrusion of the inner tapered member from the pocket hole is increased. While the paper is wound in the axial direction, the paper is wound around the outer peripheral surface of the take-up shaft and the outer surface of the inner taper member. After the paper is taken up, the inner taper member moves inward in the radial direction to move the inner taper. By moving the outer taper member in the axial direction so that the amount of protrusion from the pocket hole of the member is reduced, the winding diameter by the outer peripheral surface of the winding shaft portion and the outer surface of the inner taper member is extended over the entire width direction of the paper. Since the diameter can be reduced, the paper wound on the outer peripheral surface of the winding shaft portion and the outer surface of the inner tapered member can be easily removed from the winding shaft portion. Moreover, in this case, the outer tapered member has a tapered outer surface corresponding to the tapered inner surface of the inner tapered member, so that the tapered outer surface of the outer tapered member and the tapered inner surface of the inner tapered member are included. Since the side surfaces come into surface contact as wedge surfaces, the inner taper member can be moved in the radial direction with a relatively small force, whereby the sheet can be quickly removed from the take-up shaft portion.

本発明においては、外側テーパ部材を軸方向に挿通するとともに外側テーパ部材に回転自在に支持されかつ軸方向移動不能に固定された操作軸をさらに備えており、操作軸の先端に形成された雄ネジ部が巻取り軸部の端部に形成された雌ネジ部に螺合している(請求項2参照)。   The present invention further includes an operation shaft that is inserted through the outer taper member in the axial direction, is rotatably supported by the outer taper member, and is fixed so as not to move in the axial direction, and is a male formed at the tip of the operation shaft. The screw portion is screwed into a female screw portion formed at the end of the take-up shaft portion (see claim 2).

本発明によれば、操作軸を回転操作すると、操作軸先端の雄ネジ部が巻取り軸部の雌ネジ部に対して進入または後退することで、操作軸および外側テーパ部材が軸方向に前進または後退する。操作軸の前進時には、外側テーパ部材のテーパ状外側面が内側テーパ部材のテーパ状内側面を押圧して内側テーパ部材を半径方向外方に移動させることにより、内側テーパ部材の外側面のポケット穴からの突出量が大きくなる。また、操作軸の後退時には、外側テーパ部材のテーパ状外側面が内側テーパ部材のテーパ状内側面から離れる側に移動して内側テーパ部材が半径方向内方に移動することにより、内側テーパ部材の外側面のポケット穴からの突出量が小さくなる。この場合には、巻取り軸部の端部の雌ネジ部に螺合する操作軸先端の雄ネジ部による推力を利用して操作軸を移動させるので、内側テーパ部材の半径方向移動をより小さな力で行うことができる。   According to the present invention, when the operating shaft is rotated, the male screw portion at the tip of the operating shaft enters or retracts with respect to the female screw portion of the winding shaft portion, so that the operating shaft and the outer taper member advance in the axial direction. Or retreat. When the operation shaft advances, the tapered outer surface of the outer taper member presses the tapered inner surface of the inner taper member to move the inner taper member radially outward, thereby causing a pocket hole on the outer surface of the inner taper member. The amount of protrusion from is increased. Further, when the operating shaft is retracted, the tapered outer surface of the outer tapered member moves to the side away from the tapered inner surface of the inner tapered member, and the inner tapered member moves radially inward. The amount of protrusion from the pocket hole on the outer surface is reduced. In this case, since the operating shaft is moved using the thrust of the male screw portion at the tip of the operating shaft that is screwed into the female screw portion at the end of the winding shaft portion, the radial movement of the inner tapered member is smaller. Can be done with force.

本発明においては、スリットを介して離隔配置された第1、第2の巻取り軸部から巻取り軸部が構成されるとともに、第1の巻取り軸部が、外周面の一部に形成された第1のポケット穴と、スリットに開口する第2のポケット穴とを有し、第1、第2のポケット穴にそれぞれ第1、第2の内側テーパ部材が収容されており、外側テーパ部材が、第1、第2の内側テーパ部材の第1、第2のテーパ状内側面にそれぞれ対応しかつ係合し得る第1、第2のテーパ状外側面を有しており、用紙の始端がスリット内において第2の内側テーパ部材の外側面と第2の巻取り軸部との間で把持されるようになっている(請求項3参照)。   In the present invention, the take-up shaft portion is constituted by the first and second take-up shaft portions that are spaced apart via the slit, and the first take-up shaft portion is formed on a part of the outer peripheral surface. The first pocket hole and the second pocket hole opened in the slit, and the first and second pocket holes accommodate the first and second inner taper members, respectively, and the outer taper. The member has first and second tapered outer surfaces corresponding to and engageable with the first and second tapered inner surfaces of the first and second inner tapered members, respectively; The starting end is gripped between the outer surface of the second inner taper member and the second winding shaft portion in the slit (see claim 3).

本発明によれば、用紙を巻取り軸部に巻き取る際には、第1の内側テーパ部材が半径方向外方に移動して第1の内側テーパ部材の第1のポケット穴からの突出量が大きくなるように外側テーパ部材を軸方向に移動させた状態で、用紙を第1、第2の巻取り軸部の外周面および第1の内側テーパ部材の外側面に巻き付ける一方、用紙の巻取り後は、第1の内側テーパ部材が半径方向内方に移動して第1の内側テーパ部材の第1のポケット穴からの突出量が小さくなるように外側テーパ部材を軸方向に移動させることで、第1、第2の巻取り軸部の外周面および第1の内側テーパ部材の外側面による巻き取り径を用紙の幅方向全体にわたって縮径させることができるので、第1、第2の巻取り軸部の外周面および第1の内側テーパ部材の外側面に巻き取られた用紙を第1、第2の巻取り軸部から簡単に取り外すことができる。しかも、この場合には、外側テーパ部材が第1の内側テーパ部材の第1のテーパ状内側面に対応する第1のテーパ状外側面を有していることで、外側テーパ部材の第1のテーパ状外側面および第1の内側テーパ部材の第1のテーパ状内側面がそれぞれくさび面として面接触するので、第1の内側テーパ部材の半径方向移動を比較的小さな力で行うことができ、これにより、第1、第2の巻取り軸部からの用紙の取外しを速やかに行うことができる。   According to the present invention, when the sheet is wound around the winding shaft portion, the first inner taper member moves radially outward and the first inner taper member protrudes from the first pocket hole. In the state where the outer taper member is moved in the axial direction so as to increase, the paper is wound around the outer peripheral surfaces of the first and second take-up shafts and the outer surface of the first inner taper member. After the removal, the outer taper member is moved in the axial direction so that the first inner taper member moves inward in the radial direction and the protruding amount of the first inner taper member from the first pocket hole is reduced. Thus, the winding diameters of the outer peripheral surfaces of the first and second winding shaft portions and the outer surface of the first inner taper member can be reduced over the entire width direction of the sheet. On the outer peripheral surface of the winding shaft and the outer surface of the first inner taper member The can take the paper first, it can be easily removed from the second winding shaft portion. Moreover, in this case, the outer tapered member has the first tapered outer surface corresponding to the first tapered inner surface of the first inner tapered member, so that the first of the outer tapered member can be obtained. Since the tapered outer surface and the first tapered inner surface of the first inner tapered member are in surface contact with each other as a wedge surface, the radial movement of the first inner tapered member can be performed with a relatively small force, Thereby, it is possible to quickly remove the sheet from the first and second winding shaft portions.

さらに、本発明によれば、用紙を巻取り軸部に巻き取り始める際には、用紙の始端を第1、第2の巻取り軸部間のスリットを通して第2の内側テーパ部材の外側面と第2の巻取り軸部との間に挿入する。この状態から、第1の内側テーパ部材の第1のポケット穴からの突出量が大きくなるように外側テーパ部材を軸方向に移動させると、第2の内側テーパ部材の第2のポケット穴からの突出量も同様に大きくなり、これにより、用紙の始端を第2の内側テーパ部材の外側面と第2の巻取り軸部との間で簡単かつ確実に保持できる。一方、用紙の巻取り後は、第1の内側テーパ部材の第1のポケット穴からの突出量が小さくなるように外側テーパ部材を軸方向に移動させると、第2の内側テーパ部材の第2のポケット穴からの突出量も同様に小さくなり、その結果、第2の内側テーパ部材の外側面と第2の巻取り軸部との間で把持されていた用紙の始端の把持状態が解除される。これにより、用紙の始端を第1、第2の巻取り軸部の間のスリットから簡単に取り外すことができる。   Further, according to the present invention, when starting to take up the paper on the take-up shaft, the start end of the paper passes through the slit between the first and second take-up shafts and the outer surface of the second inner tapered member. Insert between the second winding shaft portion. From this state, when the outer taper member is moved in the axial direction so that the protruding amount of the first inner taper member from the first pocket hole is increased, the second inner taper member is removed from the second pocket hole. The amount of protrusion also increases in the same manner, so that the leading edge of the sheet can be easily and reliably held between the outer surface of the second inner tapered member and the second winding shaft portion. On the other hand, when the outer taper member is moved in the axial direction so that the amount of protrusion of the first inner taper member from the first pocket hole is reduced after the paper is wound, the second inner taper member second Similarly, the amount of protrusion from the pocket hole is also reduced, and as a result, the gripping state of the leading edge of the paper gripped between the outer surface of the second inner taper member and the second winding shaft portion is released. The As a result, the starting edge of the sheet can be easily removed from the slit between the first and second winding shafts.

このように、本発明によれば、外側テーパ部材の軸方向移動により、第1の内側テーパ部材のみならず第2の内側テーパ部材についても半径方向に移動させることができるので、第1の内側テーパ部材の第1のポケット穴からの突出量の調整のみならず、第2の内側テーパ部材による用紙の始端の把持および解除についても簡単かつ確実に行えるようになり、これにより、効率的に用紙の巻取りおよび取外しの処理を行うことができるようになる。   As described above, according to the present invention, not only the first inner tapered member but also the second inner tapered member can be moved in the radial direction by the axial movement of the outer tapered member. In addition to adjusting the amount of protrusion of the taper member from the first pocket hole, it is possible to easily and reliably grip and release the leading edge of the paper by the second inner taper member, thereby efficiently It becomes possible to perform the winding and unloading process.

本発明においては、外側テーパ部材を軸方向に挿通するとともに外側テーパ部材に回転自在に支持されかつ軸方向移動不能に固定された操作軸をさらに備え、操作軸の先端に形成された雄ネジ部が第1の巻取り軸部の端部に形成された雌ネジ部に螺合している(請求項4参照)。   In the present invention, the male screw portion formed at the tip of the operation shaft is further provided with an operation shaft that is inserted through the outer taper member in the axial direction, is rotatably supported by the outer taper member, and is fixed so as not to move in the axial direction. Is screwed into a female screw portion formed at an end of the first winding shaft portion (see claim 4).

本発明によれば、操作軸を回転操作すると、操作軸先端の雄ネジ部が第1の巻取り軸部の雌ネジ部に対して進入または後退することで、操作軸および外側テーパ部材が軸方向に前進または後退する。操作軸の前進時には、外側テーパ部材の第1のテーパ状外側面が第1の内側テーパ部材の第1のテーパ状内側面を押圧して第1の内側テーパ部材を半径方向外方に移動させることにより、第1の内側テーパ部材の外側面のポケット穴からの突出量が大きくなる。また、操作軸の後退時には、外側テーパ部材の第1のテーパ状外側面が第1の内側テーパ部材の第1のテーパ状内側面から離れる側に移動して第1の内側テーパ部材が半径方向内方に移動することにより、第1の内側テーパ部材の外側面の第1のポケット穴からの突出量が小さくなる。この場合には、第1の巻取り軸部の端部の雌ネジ部に螺合する操作軸先端の雄ネジ部による推力を利用して操作軸を移動させるので、第1の内側テーパ部材の半径方向移動をより小さな力で行うことができる。   According to the present invention, when the operating shaft is rotated, the male screw portion at the tip of the operating shaft enters or retracts from the female screw portion of the first winding shaft portion, so that the operating shaft and the outer taper member are pivoted. Move forward or backward in the direction. When the operation shaft advances, the first tapered outer surface of the outer tapered member presses the first tapered inner surface of the first inner tapered member to move the first inner tapered member radially outward. Thereby, the protrusion amount from the pocket hole of the outer surface of the first inner taper member is increased. Further, when the operating shaft is retracted, the first tapered outer surface of the outer tapered member moves to the side away from the first tapered inner surface of the first inner tapered member, and the first inner tapered member moves in the radial direction. By moving inward, the amount of protrusion from the first pocket hole on the outer surface of the first inner taper member is reduced. In this case, since the operating shaft is moved using the thrust of the male screw portion at the distal end of the operating shaft that is screwed into the female screw portion at the end of the first winding shaft portion, the first inner taper member Radial movement can be performed with less force.

さらに、本発明によれば、操作軸の回転操作により、第1の内側テーパ部材のみならず第2の内側テーパ部材についても半径方向に移動させることができるので、第1の内側テーパ部材の第1のポケット穴からの突出量の調整と同時に、第2の内側テーパ部材による用紙の始端の把持および解除を操作軸の回転操作で行えるようになり、これにより、効率的にかつ簡単な操作で用紙の巻取りおよび取外しの処理を行うことができるようになる。   Furthermore, according to the present invention, not only the first inner taper member but also the second inner taper member can be moved in the radial direction by rotating the operation shaft. At the same time as adjusting the amount of protrusion from the pocket hole 1, it becomes possible to grip and release the leading edge of the paper by the second inner taper member by rotating the operation shaft, thereby enabling efficient and simple operation. It becomes possible to perform the processing of winding and removing the paper.

本発明においては、巻取り軸部には、巻取り時の用紙の幅方向の一端側および他端側をそれぞれガイドする一対の側板部材が設けられており、各側板部材の内周側には、内側テーパ部材によりキー結合されるキー溝が形成されている(請求項5参照)。この場合には、各側板部材を巻取り軸部に連結するためのキー等の軸締結部材を別途必要としないので、構造を簡略化できる。   In the present invention, the take-up shaft portion is provided with a pair of side plate members that respectively guide one end side and the other end side in the width direction of the paper at the time of winding, and on the inner peripheral side of each side plate member In addition, a key groove that is key-connected by the inner taper member is formed (see claim 5). In this case, a shaft fastening member such as a key for connecting each side plate member to the take-up shaft portion is not required separately, so that the structure can be simplified.

本発明においては、内側テーパ部材が各側板部材を越えてその外側まで延びている(請求項6参照)。この場合には、用紙の巻取り後に内側テーパ部材の半径方向内方への移動(すなわち、内側テーパ部材のポケット穴からの突出量の減少)を各側板部材の外側から確認できるので、操作性を向上できる。   In the present invention, the inner taper member extends beyond each side plate member to the outside (see claim 6). In this case, the movement of the inner taper member inward in the radial direction (that is, the decrease in the amount of protrusion from the pocket hole of the inner taper member) can be confirmed from the outside of each side plate member after winding the paper. Can be improved.

本発明においては、当該用紙巻取り機構が、ラベル台紙貼付け装置におけるラベル剥離後の台紙を巻き取るためのものである(請求項7参照)。   In this invention, the said paper winding mechanism is for winding up the base paper after label peeling in a label base paper sticking apparatus (refer Claim 7).

以上のように、本発明に係る用紙巻取り機構によれば、外周面の一部にポケット穴が形成された巻取り軸部と、ポケット穴からの突出量が変化するようにポケット穴内で半径方向に移動自在な内側テーパ部材と、内側テーパ部材のテーパ状内側面に係合し得るテーパ状外側面を有し、軸方向に移動自在な外側テーパ部材とを設けたので、用紙を巻取り軸部に巻き取る際には、内側テーパ部材のポケット穴からの突出量が大きくなるように外側テーパ部材を軸方向に移動させた状態で、用紙を巻取り軸部の外周面および内側テーパ部材の外側面に巻き付ける一方、用紙の巻取り後は、内側テーパ部材のポケット穴からの突出量が小さくなるように外側テーパ部材を軸方向に移動させることで、巻取り軸部の外周面および内側テーパ部材の外側面による巻き取り径を用紙の幅方向全体にわたって縮径させることができるので、巻取り軸部の外周面および内側テーパ部材の外側面に巻き取られた用紙を巻取り軸部から簡単に取り外すことができる。しかも、この場合には、外側テーパ部材が内側テーパ部材のテーパ状内側面に対応するテーパ状外側面を有していることで、外側テーパ部材のテーパ状外側面および内側テーパ部材のテーパ状内側面がそれぞれくさび面として面接触するので、内側テーパ部材の半径方向移動を比較的小さな力で行うことができ、これにより、巻取り軸部からの用紙の取外しを速やかに行うことができる。   As described above, according to the paper take-up mechanism according to the present invention, the take-up shaft portion in which the pocket hole is formed in a part of the outer peripheral surface, and the radius within the pocket hole so that the protruding amount from the pocket hole changes. An inner tapered member that is movable in the direction and a tapered outer surface that can be engaged with the tapered inner surface of the inner tapered member and an outer tapered member that is movable in the axial direction are provided. When winding around the shaft portion, the outer taper member is moved in the axial direction so that the protruding amount of the inner taper member from the pocket hole is increased, and the outer peripheral surface of the winding shaft portion and the inner taper member are moved. On the other hand, after winding the paper, the outer taper member is moved in the axial direction so that the protruding amount from the pocket hole of the inner taper member becomes small, so that the outer peripheral surface and the inner Outside surface of taper member Therefore, the paper wound around the outer peripheral surface of the winding shaft and the outer surface of the inner taper member can be easily removed from the winding shaft. it can. Moreover, in this case, the outer tapered member has a tapered outer surface corresponding to the tapered inner surface of the inner tapered member, so that the tapered outer surface of the outer tapered member and the tapered inner surface of the inner tapered member are included. Since the side surfaces come into surface contact as wedge surfaces, the inner taper member can be moved in the radial direction with a relatively small force, whereby the sheet can be quickly removed from the take-up shaft portion.

また、本発明に係る用紙巻取り機構によれば、スリットを介して離隔配置された第1、第2の巻取り軸部から巻取り軸部を構成するとともに、第1の巻取り軸部に形成された第1、第2のポケット穴にそれぞれ第1、第2の内側テーパ部材を収容するようにしたので、用紙を巻取り軸部に巻き取り始める際には、用紙の始端を第1、第2の巻取り軸部間のスリットを通して第2の内側テーパ部材の外側面と第2の巻取り軸部との間に挿入し、その状態から、第2の内側テーパ部材の第2のポケット穴からの突出量が大きくなるように外側テーパ部材を軸方向に移動させることで、用紙の始端を第2の内側テーパ部材の外側面と第2の巻取り軸部との間で簡単かつ確実に保持できるようになる。   Moreover, according to the paper winding mechanism according to the present invention, the winding shaft portion is configured from the first and second winding shaft portions that are spaced from each other via the slit, and the first winding shaft portion is provided with the winding shaft portion. Since the first and second inner tapered members are accommodated in the formed first and second pocket holes, respectively, when the paper is started to be wound on the winding shaft portion, the first end of the paper is set to the first end. The second winding shaft portion is inserted between the outer surface of the second inner taper member and the second winding shaft portion through the slit between the second winding shaft portions. By moving the outer taper member in the axial direction so that the amount of protrusion from the pocket hole is increased, the starting edge of the sheet can be easily and between the outer surface of the second inner taper member and the second winding shaft portion. It can be held securely.

以下、本発明の一実施例を添付図面に基づいて説明する。
図1ないし図12は、本発明の一実施例による用紙巻取り機構を示している。ここでは、用紙巻取り機構により巻き取られる長尺の帯状の用紙として、裏面に粘着面を有するラベルが台紙に仮着されたラベル台紙からラベルが剥離された台紙を例にとる。
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
1 to 12 show a paper winding mechanism according to an embodiment of the present invention. Here, as an example of a long strip-shaped sheet wound up by a sheet winding mechanism, a mount in which a label is peeled off from a label mount in which a label having an adhesive surface on the back is temporarily attached to the mount is taken.

図1に示すように、用紙巻取り装置1は、2つの用紙巻取り機構1A、1Bを備えている。各巻取り機構1A、1Bは、台紙Sを巻き取るための巻取り軸部2、2’をそれぞれ有している。用紙巻取り装置1の上流側(図左側)には、図示していないが、ラベル貼付け装置(ラベラー)が配置されており、用紙巻取り装置1には、ラベル貼付け装置でラベル貼付け処理が施されてラベルが剥離された台紙Sが矢印方向から供給されるようになっている。供給されてきた台紙Sは、ローラ100およびテンションローラ101を経て、下方に配置された複数のローラ102および上方に配置された複数のローラ103に交互に掛け渡された後、各用紙巻取り機構1A、1Bの上方に配置されたローラ104を経ていずれかの用紙巻取り機構1A、1Bに巻き取られる。   As shown in FIG. 1, the paper winding device 1 includes two paper winding mechanisms 1A and 1B. Each winding mechanism 1A, 1B has a winding shaft portion 2, 2 'for winding the mount S, respectively. Although not shown, a label sticking device (labeler) is arranged on the upstream side (left side in the figure) of the paper take-up device 1, and the paper take-up device 1 is subjected to a label sticking process by the label sticking device. The mount S from which the label has been peeled is supplied from the direction of the arrow. The supplied mount S passes through a roller 100 and a tension roller 101 and is alternately wound around a plurality of rollers 102 disposed below and a plurality of rollers 103 disposed above, and then each sheet winding mechanism. The paper is wound around one of the paper winding mechanisms 1A and 1B via a roller 104 disposed above 1A and 1B.

図1においては、台紙Sが用紙巻取り機構1Aに巻き取られる場合を示しており(実線参照)、用紙巻取り機構1Aの巻取り軸部2に所定長さの台紙Sがロール状に巻き取られた後は、ローラ104と用紙巻取り機構1Aの巻取り軸部2との間のスパンで台紙Sが切断され、切断された台紙Sの端部が用紙巻取り機構1Bの巻取り軸部2’に係止されて巻取り軸部2’での巻取りが開始されるとともに(二点鎖線参照)、このとき、用紙巻取り機構1Aにおいては、巻取り軸部2にロール状に巻き取られた台紙Sの取外し作業が行われる。同様にして、用紙巻取り機構1Bの巻取り軸部2’に所定長さの台紙Sがロール状に巻き取られた後は、ローラ104と用紙巻取り機構1Bの巻取り軸部2’との間のスパンで台紙Sが切断され、切断された台紙Sの端部が用紙巻取り機構1Aの巻取り軸部2に係止されて巻取り軸部2での巻取りが開始されるとともに、このとき、用紙巻取り機構1Bにおいては、巻取り軸部2’にロール状に巻き取られた台紙Sの取外し作業が行われる。このようにして、用紙巻取り装置1においては、2つの用紙巻取り機構1A、1Bによる台紙Sの巻取り(つまり巻取り軸2、2’の切替え)を交互に行うことで、台紙Sの巻取りを中断することなく、連続して処理を行えるようになっている。   FIG. 1 shows a case where the mount S is wound around the paper take-up mechanism 1A (see the solid line), and a predetermined length of the mount S is wound around the take-up shaft portion 2 of the paper take-up mechanism 1A in a roll shape. After being taken, the mount S is cut by the span between the roller 104 and the take-up shaft portion 2 of the paper take-up mechanism 1A, and the end of the cut mount S is taken up by the take-up shaft of the paper take-up mechanism 1B. Winding at the winding shaft portion 2 ′ is started by being locked by the portion 2 ′ (see the chain double-dashed line), and at this time, in the paper winding mechanism 1A, the winding shaft portion 2 is formed in a roll shape. The removal work of the wound mount S is performed. Similarly, after the mount S having a predetermined length is wound around the winding shaft 2 'of the paper winding mechanism 1B in a roll shape, the roller 104 and the winding shaft 2' of the paper winding mechanism 1B The mount S is cut at a span between the ends, the end of the cut mount S is locked to the take-up shaft 2 of the paper take-up mechanism 1A, and winding at the take-up shaft 2 is started. At this time, in the paper take-up mechanism 1B, the work of removing the mount S wound in a roll shape on the take-up shaft portion 2 ′ is performed. In this way, in the paper winding device 1, the mounting of the mount S by the two paper winding mechanisms 1A and 1B (that is, switching of the winding shafts 2 and 2 ') is performed alternately, thereby Processing can be performed continuously without interrupting winding.

なお、各ローラ102は、図1中の実線に示す下方位置と、同図中の一点鎖線で示す上方位置との間のバッファゾーンを移動可能に設けられており、巻取り軸部2、2’を切り替える際には、各ローラ102をこれら上方位置および下方位置間で移動させることにより、巻取り軸部2、2’の切替えをスムーズに行えるようになっている。   Each roller 102 is provided to be movable in a buffer zone between a lower position indicated by a solid line in FIG. 1 and an upper position indicated by a one-dot chain line in FIG. When switching ', each roller 102 is moved between the upper position and the lower position, so that the winding shaft portions 2, 2' can be switched smoothly.

用紙巻取り機構1Aは、図2および図3に示すように、巻取り時の台紙Sの幅方向の一端側および他端側をそれぞれガイドする円板状の一対の側板部材3(3、3)を有している(図1参照)。巻取り軸部2は、各側板部材3、3を挿通して軸方向に延びている。また、用紙巻取り機構1Aは、巻取り軸部2を回転駆動するための減速機付サーボモータ200を有している。サーボモータ200の出力軸200aは、壁パネル201に回転自在に支持されており、その軸端にはフランジ部材202が固定されている。 As shown in FIGS. 2 and 3, the sheet winding mechanism 1 </ b> A includes a pair of disk-shaped side plate members 3 (3 1 , 3) that respectively guide one end side and the other end side in the width direction of the mount S during winding. 3 2 ) (see FIG. 1). The winding shaft portion 2 extends in the axial direction through the side plate members 3 1 , 3 2 . Further, the sheet winding mechanism 1 </ b> A has a servo motor 200 with a reduction gear for driving the winding shaft portion 2 to rotate. An output shaft 200a of the servo motor 200 is rotatably supported by the wall panel 201, and a flange member 202 is fixed to the shaft end.

巻取り軸部2は、図2ないし図4に示すように、スリットsを介して半径方向に離隔配置された円筒状の第1の巻取り軸部20および略半円柱状の第2の巻取り軸部21から構成されており、第1の巻取り軸部20の外周面20Aおよび第2の巻取り軸部21の外周面21Aにより、全体として円筒状の外周面を有している。第1、第2の巻取り軸部20、21の基端側の底部20B、21Bは、ベース部材22を介してフランジ部材202に固定されている。   As shown in FIGS. 2 to 4, the winding shaft portion 2 includes a cylindrical first winding shaft portion 20 and a substantially semi-columnar second winding that are spaced apart from each other in the radial direction via slits s. The winding shaft portion 21 includes a cylindrical outer peripheral surface as a whole by the outer peripheral surface 20A of the first winding shaft portion 20 and the outer peripheral surface 21A of the second winding shaft portion 21. The bottom portions 20 </ b> B and 21 </ b> B on the base end side of the first and second winding shaft portions 20 and 21 are fixed to the flange member 202 via the base member 22.

巻取り軸部2のスリットsは、巻取り軸部2の中心軸線O−O’から離れた位置に配置され、巻取り軸部2の外周面に開口するとともに軸方向に延びている。相対的に大形の第1の巻取り軸部20は、外周面20Aの一部に形成されかつ外周面20Aに開口する第1のポケット穴20aと、スリットsに開口する第2のポケット穴20bとを有しており、各ポケット穴20a、20bは第1の巻取り軸部20の内部で連通している。各ポケット穴20a、20bは、第1の巻取り軸部20の軸方向中央部から基端側の底部20Bの手前側まで軸方向に延びている。   The slit s of the winding shaft portion 2 is disposed at a position away from the central axis O-O ′ of the winding shaft portion 2, opens in the outer peripheral surface of the winding shaft portion 2, and extends in the axial direction. The relatively large first take-up shaft portion 20 includes a first pocket hole 20a formed in a part of the outer peripheral surface 20A and opened in the outer peripheral surface 20A, and a second pocket hole opened in the slit s. 20 b, and the pocket holes 20 a and 20 b communicate with each other inside the first winding shaft portion 20. Each pocket hole 20a, 20b extends in the axial direction from the axial center of the first winding shaft 20 to the front side of the bottom 20B on the base end side.

第1のポケット穴20aには、第1の内側テーパ部材23が半径方向移動自在に収容され、第2のポケット穴20bには、第2の内側テーパ部材24が半径方向移動自在に収容されており、第1、第2の内側テーパ部材23、24が半径方向に移動することで、第1、第2のポケット穴20a、20bからの各内側テーパ部材23、24の突出量が変化するようになっている。また、第1、第2のポケット穴20a、20bを連通する内部空間20Cには、第1、第2の内側テーパ部材23、24を半径方向に移動させるためのブラケット部材(外側テーパ部材)25が配置されている。   A first inner tapered member 23 is accommodated in the first pocket hole 20a in a radially movable manner, and a second inner tapered member 24 is accommodated in the second pocket hole 20b in a radially movable manner. As the first and second inner tapered members 23 and 24 move in the radial direction, the amount of protrusion of the inner tapered members 23 and 24 from the first and second pocket holes 20a and 20b changes. It has become. A bracket member (outer taper member) 25 for moving the first and second inner taper members 23 and 24 in the radial direction in the inner space 20C communicating with the first and second pocket holes 20a and 20b. Is arranged.

第1の内側テーパ部材23は、第1のポケット穴20aの外側に配置されかつ台紙Sの幅wを越えて軸方向に直線状に延びる(すなわち、台紙Sの幅方向全体にわたって延在する)とともに各側板部材3、3を越えてその外側まで延びる円筒状の外側面23aと、外側面23aに対向して第1のポケット穴20aの内側に配置され、巻取り軸部2の基端側に向かって徐々に小径となるように軸方向にテーパ状に延びる第1のテーパ状内側面23bとを有している。同様に、第2の内側テーパ部材24は、第2のポケット穴20bの外側に配置されかつ台紙Sの幅wを越えて軸方向に直線状に延びる(すなわち、台紙Sの幅方向全体にわたって延在する)円筒状の外側面24aと、外側面24aに対向して第2のポケット穴20bの内側に配置され、巻取り軸部2の基端側に向かって徐々に小径となるように軸方向にテーパ状に延びる第2のテーパ状内側面24bとを有している。 The first inner taper member 23 is disposed outside the first pocket hole 20a and extends linearly in the axial direction beyond the width w of the mount S (that is, extends over the entire width direction of the mount S). A cylindrical outer surface 23a extending beyond each side plate member 3 1 , 3 2 to the outside thereof, and disposed on the inner side of the first pocket hole 20a so as to face the outer surface 23a. It has a first tapered inner side surface 23b extending in a taper shape in the axial direction so as to gradually decrease in diameter toward the end side. Similarly, the second inner taper member 24 is disposed outside the second pocket hole 20b and extends linearly in the axial direction beyond the width w of the mount S (that is, extends over the entire width direction of the mount S). A cylindrical outer surface 24a and an inner surface that is disposed inside the second pocket hole 20b so as to face the outer surface 24a and gradually decreases in diameter toward the proximal end side of the winding shaft portion 2. And a second tapered inner side surface 24b extending in a taper direction.

ブラケット部材25は、第1の内側テーパ部材23の第1のテーパ状内側面23bに対応しかつこれに係合し得る第1のテーパ状外側面25aと、これと逆側に配置されるとともに、第2の内側テーパ部材24の第1のテーパ状内側面24bに対応しかつこれに係合し得る第2のテーパ状外側面25bとを有している。なお、ブラケット部材25と異なり、第1、第2の内側テーパ部材23、24は別部材であるため、第1、第2のテーパ状内側面23b、24bは、厳密な意味でのテーパ面ではないが、ブラケット部材25の第1、第2のテーパ状外側面25a、25bにそれぞれ対応しつつ軸方向に対して傾斜して配設されているため、本明細書中では、これらも併せてテーパ面と呼称することにした。   The bracket member 25 corresponds to the first taper inner surface 23b of the first inner taper member 23 and is disposed on the opposite side to the first taper outer surface 25a that can be engaged with the first taper inner surface 23b. The second inner tapered member 24 has a second tapered outer surface 25b that corresponds to and can engage with the first tapered inner surface 24b. Unlike the bracket member 25, the first and second inner tapered members 23 and 24 are separate members. Therefore, the first and second tapered inner side surfaces 23b and 24b are taper surfaces in a strict sense. However, in the present specification, these are also combined with the first and second tapered outer surfaces 25a and 25b of the bracket member 25 so as to be inclined with respect to the axial direction. We decided to call it a tapered surface.

第1の内側テーパ部材23の外側面23aを含む上側部分は、図3に示すように、各側板部材3、3に内周側にそれぞれ形成された係合溝3a、3aにそれぞれ係合しており、各係合溝3a、3aは、第1の内側テーパ部材23によりキー結合されるキー溝として機能している。この場合には、各側板部材3、3を巻取り軸部2に連結するためのキー等の軸締結部材を別途必要としないので、構造を簡略化できる。各側板部材3、3の中央には、両端が開口する筒状部材26、27がそれぞれ取り付けられており、これらの筒状部材26、27の内周側にも、第1の内側テーパ部材23によりキー結合されるキー溝として機能する係合溝26a、27aがそれぞれ形成されている。また、スリットs内において、第2の内側テーパ部材24と対向する第2の巻取り軸部21の部位には、たとえばラバー製のプレート部材28が埋設されている。 As shown in FIG. 3, the upper portion including the outer surface 23 a of the first inner taper member 23 has engaging grooves 3 1 a, 3 2 formed on the inner peripheral sides of the side plate members 3 1 , 3 2 , respectively. Each engagement groove 3 1 a, 3 2 a functions as a key groove that is key-coupled by the first inner taper member 23. In this case, a shaft fastening member such as a key for connecting the side plate members 3 1 , 3 2 to the take-up shaft portion 2 is not required separately, so that the structure can be simplified. At the center of each side plate member 3 1 , 3 2 , cylindrical members 26, 27 that are open at both ends are respectively attached, and the first inner taper is also provided on the inner peripheral side of these cylindrical members 26, 27. Engagement grooves 26a and 27a functioning as key grooves that are key-coupled by the member 23 are formed. In the slit s, a rubber plate member 28 is embedded in a portion of the second winding shaft portion 21 that faces the second inner taper member 24.

第1の内側テーパ部材23の第1のテーパ状内側面23bの左右端部には、図4に示すように、ブラケット部材25の側に向かって半径方向内方に延びかつ左右側方に張り出す左右一対の張出部23cが設けられている。ブラケット部材25の第1のテーパ状外側面25aを含む外側部分は、第1の内側テーパ部材23の第1のテーパ状内側面23bおよび各張出部23cで限定される凹部内に収容されている。また、第1の巻取り軸部20の第1のポケット穴20aには、第1の内側テーパ部材23の各張出部23cを受け入れる左右一対の凹部20dが形成されている。第1の内側テーパ部材23の半径方向移動時には、第1の内側テーパ部材23の各張出部23cが各凹部20dの各端面20d、20dの間を移動する。 As shown in FIG. 4, the left and right ends of the first tapered inner side surface 23b of the first inner tapered member 23 extend radially inward toward the bracket member 25 and stretch to the left and right sides. A pair of left and right overhang portions 23c are provided. The outer portion including the first tapered outer surface 25a of the bracket member 25 is accommodated in a recess defined by the first tapered inner side surface 23b and the protruding portions 23c of the first inner tapered member 23. Yes. The first pocket hole 20 a of the first winding shaft portion 20 is formed with a pair of left and right recesses 20 d that receive the overhang portions 23 c of the first inner taper member 23. When the first inner taper member 23 moves in the radial direction, the overhang portions 23c of the first inner taper member 23 move between the end surfaces 20d 1 and 20d 2 of the recesses 20d.

同様に、第2の内側テーパ部材24の第2のテーパ状内側面24bの左右端部には、ブラケット部材25の側に向かって半径方向内方に延びかつ左右側方に張り出す左右一対の張出部24cが設けられている。ブラケット部材25の第2のテーパ状外側面25bを含む外側部分は、第2の内側テーパ部材24の第2のテーパ状内側面24bおよび各張出部24cで限定される凹部内に収容されている。また、第1の巻取り軸部20の第2のポケット穴20bには、第2の内側テーパ部材24の各張出部24cを受け入れる左右一対の凹部20eが形成されている。第2の内側テーパ部材24の半径方向移動時には、第2の内側テーパ部材24の各張出部24cが各凹部20eの各端面20e、20eの間を移動する。 Similarly, on the left and right ends of the second tapered inner surface 24b of the second inner tapered member 24, a pair of left and right extending radially inward toward the bracket member 25 and projecting to the left and right sides. An overhang portion 24c is provided. The outer portion including the second tapered outer surface 25b of the bracket member 25 is accommodated in a recess defined by the second tapered inner surface 24b of the second inner tapered member 24 and the overhang portions 24c. Yes. The second pocket hole 20b of the first winding shaft portion 20 is formed with a pair of left and right recesses 20e for receiving the overhang portions 24c of the second inner taper member 24. When the second inner taper member 24 moves in the radial direction, the overhang portions 24c of the second inner taper member 24 move between the end surfaces 20e 1 and 20e 2 of the recesses 20e.

円筒状の第1の巻取り軸部20の内部空間20Cには、第1の巻取り軸部20の軸芯O−O’を通って軸方向に延びる操作軸29が配設されている。操作軸29は、第1の巻取り軸部20の端部20Dを挿通して軸方向に延びており、手前側端には操作つまみ29Aが設けられ、先端には雄ネジ部29aが形成されている。雄ネジ部29aは、第1の巻取り軸部20の底部20Bに形成された雌ネジ部20cに螺合している。操作軸29は、ブラケット部材25を軸方向に挿通するとともに、ブラケット部材25に回転自在に支持されかつ軸方向移動不能に固定されている。 The internal space 20C of the cylindrical first winding shaft portion 20, the operating shaft 29 extending axially through the axis O 1 -O 1 'of the first winding shaft portion 20 is disposed Yes. The operation shaft 29 extends in the axial direction through the end portion 20D of the first winding shaft portion 20, and is provided with an operation knob 29A at the front end and a male screw portion 29a at the tip. ing. The male screw portion 29 a is screwed into a female screw portion 20 c formed on the bottom portion 20 </ b> B of the first winding shaft portion 20. The operation shaft 29 is inserted through the bracket member 25 in the axial direction, is rotatably supported by the bracket member 25, and is fixed so as not to move in the axial direction.

この構成により、操作者が操作つまみ29Aを介して操作軸29を回転操作すると、操作軸29の雄ネジ部29aが第1の巻取り軸部20の底部20Bの雌ネジ部20cに対して進入または後退することにより、操作軸29およびブラケット部材25が軸方向に前進または後退するようになっており、ブラケット部材25が軸方向に移動することで、第1、第2の内側テーパ部材23、24が半径方向に移動する。   With this configuration, when the operator rotates the operation shaft 29 via the operation knob 29A, the male screw portion 29a of the operation shaft 29 enters the female screw portion 20c of the bottom portion 20B of the first winding shaft portion 20. Alternatively, the operating shaft 29 and the bracket member 25 are moved forward or backward in the axial direction by moving backward, and the first and second inner taper members 23, when the bracket member 25 moves in the axial direction, 24 moves in the radial direction.

筒状部材27の外周面には、図5に示すように、レバー30が設けられており、レバー30の軸部には雄ネジ部30aが形成されている。一方、筒状部材27には、これを半径方向に挿通する貫通孔が形成されており、当該貫通孔には、レバー軸部の雄ネジ部30aが螺合する雌ネジ部27bが形成されている。レバー30を回転させてレバー軸部の雄ネジ部30aの先端を第1の巻取り軸部20の外周面に圧接させることで、レバー軸部の雄ネジ部30aは、筒状部材27を第1の巻取り軸部20に固定する止めネジとして機能している。   As shown in FIG. 5, a lever 30 is provided on the outer peripheral surface of the cylindrical member 27, and a male screw portion 30 a is formed on the shaft portion of the lever 30. On the other hand, the cylindrical member 27 is formed with a through hole through which it is inserted in the radial direction, and a female screw portion 27b into which the male screw portion 30a of the lever shaft portion is screwed is formed in the through hole. Yes. By rotating the lever 30 to bring the tip of the male screw portion 30a of the lever shaft portion into pressure contact with the outer peripheral surface of the first winding shaft portion 20, the male screw portion 30a of the lever shaft portion causes the cylindrical member 27 to It functions as a set screw to be fixed to the one take-up shaft portion 20.

次に、上述した用紙巻取り機構1Aによる台紙巻取り時の作業手順について、図6ないし図9を用いて説明する。
まず、図6に示すように、操作つまみ29Aで操作軸29を回転操作するとともに軸方向に移動させて操作軸29の雄ネジ部29aを第1の巻取り軸部20の底部20Bの雌ネジ部20cから外して後退させることにより、操作軸29およびブラケット部材25を軸方向に後退させるとともに、用紙巻取り機構1Aから筒状部材27および側板部材3を取り外す。
Next, an operation procedure at the time of winding the mount by the above-described sheet winding mechanism 1A will be described with reference to FIGS.
First, as shown in FIG. 6, the operating shaft 29 is rotated by the operation knob 29 </ b> A and moved in the axial direction so that the male screw portion 29 a of the operating shaft 29 is turned into the female screw on the bottom 20 </ b> B of the first winding shaft portion 20. by retracting removed from section 20c, together with retreating the operation shaft 29 and the bracket member 25 in the axial direction, detaching the cylindrical member 27 and the side plate member 3 2 from the sheet winding mechanism 1A.

このとき、図7に示すように、第1の内側テーパ部材23が半径方向内方に移動されて、第1の内側テーパ部材23の第1のポケット穴20aからの突出量が小さくなるとともに、第2の内側テーパ部材24が半径方向内方に移動されて、第2の内側テーパ部材24の第2のポケット穴20bからの突出量が小さくなり、スリットs内において、第2の内側テーパ部材24の外側面24aと第2の巻取り軸部21側のプレート部材28との間に隙間が形成される。この状態から、台紙Sの始端Saを当該隙間に挿入する。   At this time, as shown in FIG. 7, the first inner taper member 23 is moved radially inward, and the amount of protrusion of the first inner taper member 23 from the first pocket hole 20a is reduced. The second inner taper member 24 is moved inward in the radial direction, so that the amount of protrusion of the second inner taper member 24 from the second pocket hole 20b is reduced, and the second inner taper member in the slit s. A gap is formed between the outer surface 24a of 24 and the plate member 28 on the second winding shaft portion 21 side. From this state, the starting end Sa of the mount S is inserted into the gap.

次に、図8に示すように、側板部材3および筒状部材27を組み込む。このとき、側板部材3の内周側の係合溝3aおよび筒状部材27の係合溝27aを第1の内側テーパ部材23の外側面23aを含む外側部分に係合させて、筒状部材27を側板部材3に固定するとともに、レバー30を操作して、筒状部材27を第1の巻取り軸部20の外周面に固定する。側板部材3の組込時には、側板部材3との間隔は、台紙Sの幅wよりも若干大きな寸法に設定される。 Next, as shown in FIG. 8, incorporating a plate member 3 2 and the tubular member 27. At this time, by engaging the engaging groove 27a of the side plate member 3 of the second inner circumferential side engaging groove 3 2 a and the tubular member 27 to the outer portion including an outer surface 23a of the first inner tapered member 23, It is fixed a tubular member 27 on the side plate member 3 2, by operating the lever 30, to secure the tubular member 27 on the outer peripheral surface of the first winding shaft portion 20. When the side plate member 3 2 built, the interval between the side plate member 3 1 is set slightly larger than the width w of the mount S.

また、図9に示すように、操作つまみ29Aで操作軸29を軸方向に前進させ、先端の雄ネジ部29aを第1の巻取り軸部20の底部20Bの雌ネジ部20cに挿入させるとともに、操作つまみ29Aで操作軸29を回転操作し、雄ネジ部29aを雌ネジ部20cに螺合させてさらに前進させることにより、操作軸29とともにブラケット部材25を軸方向に前進させる。   Further, as shown in FIG. 9, the operation shaft 29 is advanced in the axial direction by the operation knob 29 </ b> A, and the male screw portion 29 a at the tip is inserted into the female screw portion 20 c of the bottom portion 20 </ b> B of the first winding shaft portion 20. The operation shaft 29 is rotated by the operation knob 29A, and the male screw portion 29a is screwed into the female screw portion 20c to be further advanced, whereby the bracket member 25 is advanced in the axial direction together with the operation shaft 29.

すると、ブラケット部材25の第1のテーパ状外側面25aが第1の内側テーパ部材23の第1のテーパ状内側面23bと係合して第1の内側テーパ部材23を半径方向外方に移動させることにより、第1の内側テーパ部材23の外側面23aの第1のポケット穴20aからの突出量が大きくなる(図4参照)。それと同時に、ブラケット部材25の第2のテーパ状外側面25bが第2の内側テーパ部材24の第2のテーパ状内側面24bと係合して第2の内側テーパ部材24を半径方向外方に移動させることにより、第2の内側テーパ部材24の外側面24aの第2のポケット穴20bからの突出量が大きくなる(同図参照)。これにより、巻取り軸部2とは別個に設けられた部材を必要とすることなく、台紙Sの始端Saを第2の内側テーパ部材24の外側面24aと第2の巻取り軸部21側のプレート部材28との間で簡単かつ確実に把持することができる(同図参照)。   Then, the first taper outer surface 25a of the bracket member 25 engages with the first taper inner surface 23b of the first inner taper member 23 to move the first inner taper member 23 radially outward. By doing so, the protruding amount of the outer side surface 23a of the first inner taper member 23 from the first pocket hole 20a is increased (see FIG. 4). At the same time, the second taper outer surface 25b of the bracket member 25 engages with the second taper inner surface 24b of the second inner taper member 24 so that the second inner taper member 24 is radially outward. By moving, the amount of protrusion of the outer side surface 24a of the second inner taper member 24 from the second pocket hole 20b increases (see the same figure). Thus, the start end Sa of the mount S can be connected to the outer surface 24a of the second inner tapered member 24 and the second winding shaft portion 21 side without requiring a member provided separately from the winding shaft portion 2. It can be easily and reliably gripped with the plate member 28 (see the figure).

この状態から、減速機付きサーボモータ200(図2)を駆動して出力軸200aを回転させると、巻取り軸部2とともに各側板部材3、3および各筒状部材26,27が回転し、これにより、第1の巻取り軸部20の外周面20A、第2の巻取り軸部21の外周面21Aおよび第1の内側テーパ部材23の外側面23aの周りに台紙Sが巻き付けられる(図4参照)。 From this state, when the servo motor 200 with a speed reducer (FIG. 2) is driven to rotate the output shaft 200a, the side plate members 3 1 , 3 2 and the cylindrical members 26, 27 rotate together with the take-up shaft portion 2. Thus, the mount S is wound around the outer peripheral surface 20A of the first winding shaft portion 20, the outer peripheral surface 21A of the second winding shaft portion 21, and the outer surface 23a of the first inner taper member 23. (See FIG. 4).

次に、用紙巻取り機構1Aに巻き取られた台紙Sを巻取り軸部2から取り外す際の作業手順について、図10ないし図12を用いて説明する。
図10は、用紙巻取り機構1Aに台紙Sが所定長さ分だけロール状に巻き取られた状態を示しており、図中、台紙Sのロール体が参照符号Sで表されている。
Next, an operation procedure for removing the mount S taken up by the paper take-up mechanism 1A from the take-up shaft portion 2 will be described with reference to FIGS.
Figure 10 is a mount S to the sheet winding mechanism 1A is shows a state of being wound only in a roll form predetermined length fraction, in the figure, are represented roll of the backing sheet S is by reference numeral S R.

この状態から、操作つまみ29Aで操作軸29を回転操作するとともに軸方向に移動させて操作軸29の雄ネジ部29aを第1の巻取り軸部20の底部20Bの雌ネジ部20cから外して後退させることにより、操作軸29およびブラケット部材25を軸方向に後退させるとともに(図11参照)、用紙巻取り機構1Aから筒状部材27および側板部材3を取り外す。 From this state, the operating shaft 29 is rotated by the operating knob 29A and moved in the axial direction to remove the male threaded portion 29a of the operating shaft 29 from the female threaded portion 20c of the bottom 20B of the first winding shaft portion 20. by retracting, (see FIG. 11) along with retracting the operation shaft 29 and the bracket member 25 in the axial direction, detaching the cylindrical member 27 and the side plate member 3 2 from the sheet winding mechanism 1A.

操作軸29およびブラケット部材25が軸方向に後退することにより、ブラケット部材25の第1のテーパ状外側面25aと第1の内側テーパ部材23の第1のテーパ状内側面23bとの間に隙間が形成されようとするが、このとき、第1の内側テーパ部材23の外側面23aに作用するロール体Sからの巻付圧により、または、操作者が筒状部材27を側板部材3から取り外した状態で第1の内側テーパ部材23の外側面23aを半径方向内方に押し込むことにより、上記隙間は解消する。その結果、図11に示すように、第1の内側テーパ部材23の第1のポケット穴20aからの突出量が小さくなって、巻取り軸部2の外周面および第1の内側テーパ部材23の外側面23aによる巻き取り径を台紙Sの幅方向全体にわたって縮径できる。 When the operation shaft 29 and the bracket member 25 are retracted in the axial direction, a gap is formed between the first tapered outer surface 25a of the bracket member 25 and the first tapered inner surface 23b of the first inner tapered member 23. There is about to be formed, this time, the winding pressure from the roll S R which acts on the outer surface 23a of the first inner tapered member 23, or the operator side plate of the cylindrical member 27 member 3 2 When the outer surface 23a of the first inner taper member 23 is pushed inward in the radial direction in a state where the first inner taper member 23 is removed from the inner space, the gap is eliminated. As a result, as shown in FIG. 11, the protrusion amount of the first inner taper member 23 from the first pocket hole 20a is reduced, and the outer peripheral surface of the winding shaft portion 2 and the first inner taper member 23 The winding diameter by the outer side surface 23a can be reduced over the entire width direction of the mount S.

また、操作軸29およびブラケット部材25が軸方向に後退することにより、ブラケット部材25の第2のテーパ状外側面25bから第2の内側テーパ部材24の第2のテーパ状内側面24bに対して作用していた押付圧がなくなるので、台紙Sの始端Saに作用していた、第2の内側テーパ部材24の外側面24aと第2の巻取り軸部21側のプレート部材28との間の把持圧もなくなる。   Further, when the operation shaft 29 and the bracket member 25 are retracted in the axial direction, the second tapered outer side surface 25b of the second inner tapered member 24 is extended from the second tapered outer side surface 25b of the bracket member 25. Since the pressing pressure that has acted is eliminated, the gap between the outer surface 24a of the second inner taper member 24 and the plate member 28 on the second winding shaft portion 21 side that has acted on the starting end Sa of the mount S is eliminated. There is no gripping pressure.

したがって、図12に示すように、ロール体Sを含む台紙S全体を手前側(図示矢印方向)に移動させることで、始端Saが巻取り軸部2に把持されかつ巻取り軸部2の外周面および第1の内側テーパ部材23の外側面23aに巻き取られていた台紙Sを巻取り軸部2から簡単に取り外すことができる。 Accordingly, as shown in FIG. 12, the front side across the backing sheet S including the roll S R by moving the (arrow direction), starting Sa is grasped by the take-up shaft section 2 and the winding shaft section 2 The mount S that has been wound around the outer peripheral surface and the outer surface 23 a of the first inner taper member 23 can be easily removed from the winding shaft portion 2.

しかも、ブラケット部材25が第1の内側テーパ部材23の第1のテーパ状内側面23bに対応する第1のテーパ状外側面25aを有していることで、ブラケット部材25の第1のテーパ状外側面23bおよび第1の内側テーパ部材23の第1のテーパ状内側面23bがそれぞれくさび面として面接触するので、ブラケット部材25の軸方向移動および第1の内側テーパ部材23の半径方向移動を比較的小さな力で行うことができ、これにより、巻取り軸部2からの台紙Sの取外しを速やかに行うことができる。   In addition, since the bracket member 25 has the first tapered outer surface 25a corresponding to the first tapered inner surface 23b of the first inner tapered member 23, the first tapered shape of the bracket member 25 is obtained. Since the outer side surface 23b and the first tapered inner side surface 23b of the first inner tapered member 23 are in surface contact with each other as a wedge surface, the bracket member 25 is moved in the axial direction and the first inner tapered member 23 is moved in the radial direction. This can be performed with a relatively small force, whereby the mount S can be quickly removed from the winding shaft portion 2.

さらに、第1の巻取り軸部2の底部20Bの雌ネジ部20cに螺合する操作軸29先端の雄ネジ部29aによる推力を利用して操作軸29およびブラケット部材25が軸方向に移動するので、ブラケット部材25の軸方向移動および第1の内側テーパ部材23の半径方向移動をより小さな力で行うことができる。   Further, the operating shaft 29 and the bracket member 25 are moved in the axial direction by using the thrust generated by the male screw portion 29a at the tip of the operating shaft 29 screwed into the female screw portion 20c of the bottom portion 20B of the first winding shaft portion 2. Therefore, the axial movement of the bracket member 25 and the radial movement of the first inner taper member 23 can be performed with a smaller force.

また、ブラケット部材25の軸方向移動により、第1の内側テーパ部材23のみならず第2の内側テーパ部材24についても半径方向に移動させることができるので、第1の内側テーパ部材23の第1のポケット穴20aからの突出量の調整のみならず、第2の内側テーパ部材24による用紙Sの始端Saの把持および解除についても、操作軸29の回転操作のみで簡単かつ確実に行えるようになり、これにより、効率的に用紙の巻取りおよび取外しの処理を行うことができるようになる。   Further, since the bracket member 25 is moved in the axial direction, not only the first inner taper member 23 but also the second inner taper member 24 can be moved in the radial direction. In addition to adjusting the amount of protrusion from the pocket hole 20a, the grip and release of the starting edge Sa of the paper S by the second inner taper member 24 can be easily and reliably performed only by rotating the operation shaft 29. Thus, it is possible to efficiently perform the winding and unloading processing of the sheet.

以上、本発明に好適な実施例について説明したが、本発明の適用はこれに限定されるものではなく、本発明には種々の変形例が含まれる。以下に変形例のいくつかの例を挙げておく。   As mentioned above, although the suitable example for the present invention was described, application of the present invention is not limited to this, and various modifications are included in the present invention. Some examples of modifications are given below.

<第1の変形例>
前記実施例では、好ましい態様として、用紙巻取り装置1が2つの用紙巻取り機構1A、1Bから構成された例を示したが、本発明の適用はこれに限定されない。用紙巻取り装置1は、3つ以上の用紙巻取り機構から構成されていてもよいし、また、単一の用紙巻取り機構から構成されていてもよい。
<First Modification>
In the above-described embodiment, an example in which the sheet winding device 1 includes two sheet winding mechanisms 1A and 1B has been shown as a preferable mode. However, the application of the present invention is not limited to this. The paper winding device 1 may be configured by three or more paper winding mechanisms, or may be configured by a single paper winding mechanism.

<第2の変形例>
前記実施例では、好ましい態様として、巻取り軸部2が第1、第2の巻取り軸部20、21から構成された例を示したが、巻取り軸部2は、概略円柱状の単一の巻取り軸部から構成されていてもよい。その場合、巻取り軸部の外周面に台紙Sの始端を保持するための保持部を別途設ける必要がある。
<Second Modification>
In the said Example, although the winding shaft part 2 showed the example comprised from the 1st, 2nd winding shaft parts 20 and 21 as a preferable aspect, the winding shaft part 2 is a substantially cylindrical single unit. You may be comprised from the one winding axial part. In that case, it is necessary to separately provide a holding portion for holding the starting end of the mount S on the outer peripheral surface of the winding shaft portion.

<第3の変形例>
前記実施例では、第1の内側テーパ部材23の各張出部23cと、第1のポケット穴20aの各凹部20dの各端面20d、20dとの間に単に空所のみが形成された例を示したが(図4参照)、本発明の適用はこれに限定されない。たとえば、第1の内側テーパ部材23の各張出部23cと、第1のポケット穴20aの各凹部20dの端面20dとの間に圧縮バネを配設するようにしてもよい。この場合、操作軸29およびブラケット部材25の後退時には、第1の内側テーパ部材23が圧縮バネの反発力により半径方向内方に容易に移動できるようになる。
<Third Modification>
In the above-described embodiment, only voids are formed between the protruding portions 23c of the first inner tapered member 23 and the end surfaces 20d 1 and 20d 2 of the concave portions 20d of the first pocket hole 20a. Although an example has been shown (see FIG. 4), the application of the present invention is not limited to this. For example, each projecting portion 23c of the first inner tapered member 23 may be arranged a compression spring between the end face 20d 1 of each recess 20d of the first pocket hole 20a. In this case, when the operation shaft 29 and the bracket member 25 are retracted, the first inner taper member 23 can be easily moved inward in the radial direction by the repulsive force of the compression spring.

同様に、前記実施例では、第2の内側テーパ部材24の各張出部24cと、第2のポケット穴20bの各凹部20eの各端面20e、20eとの間に単に空所のみが形成された例を示したが(図4参照)、本発明の適用はこれに限定されない。たとえば、第2の内側テーパ部材24の各張出部24cと、第2のポケット穴20bの各凹部20eの端面20eとの間に圧縮バネを配設するようにしてもよい。この場合、操作軸29およびブラケット部材25の後退時には、第2の内側テーパ部材24が圧縮バネの反発力により半径方向内方に容易に移動できるようになる。 Similarly, in the above-described embodiment, only voids are provided between the protruding portions 24c of the second inner tapered member 24 and the end faces 20e 1 and 20e 2 of the concave portions 20e of the second pocket hole 20b. Although the formed example is shown (see FIG. 4), the application of the present invention is not limited to this. For example, each projecting portion 24c of the second inner tapered member 24 may be arranged a compression spring between the end face 20e 2 of the recesses 20e of the second pocket bore 20b. In this case, when the operating shaft 29 and the bracket member 25 are retracted, the second inner tapered member 24 can easily move inward in the radial direction by the repulsive force of the compression spring.

<第4の変形例>
前記実施例では、長尺の帯状の用紙として、裏面に粘着面を有するラベルが台紙に仮着されたラベル台紙からラベルが剥離された台紙を例にとって説明したが、本発明の適用はこれに限定されるものではなく、その他の連続用紙でもよく、またフィルム用紙であってもよい。
<Fourth Modification>
In the above-described embodiment, as an example of a long strip-shaped paper, an explanation has been given by taking, as an example, a mount on which a label having an adhesive surface on the back is temporarily attached to a mount, but the label is peeled off.
