The

ガイド部材１００は、帯状部材２を成形ドラム４の外周面４ｆの上に案内するガイド部１１０と、ガイド部１１０の先端側に設けられたヘッド部１２０とを備える。   The guide member 100 includes a guide portion 110 that guides the belt-like member 2 onto the outer peripheral surface 4 f of the forming drum 4, and a head portion 120 provided on the distal end side of the guide portion 110.

The pressing surface 116 may be elastically supported so as to be maintained at a predetermined interval.

剥離手段７は、押え面１１６が貼付動作部として機能するように押え面１１６と成形ドラム４の外周面４ｆとの間の間隔を所定の間隔に維持するガイド部材駆動手段１０１と、ガイド部材駆動手段１０１を制御する制御手段１０と、押え面１１６が貼付動作部として機能している状態においてライナー２５の進行方向を変更させる剥離動作部として機能する先端縁部１１７と、先端縁部１１７で進行方向が変更されたライナー２５を巻き取る巻取手段９とを備えて構成される。   The peeling means 7 includes a guide member driving means 101 that maintains a predetermined distance between the pressing surface 116 and the outer peripheral surface 4f of the forming drum 4 so that the pressing surface 116 functions as a sticking operation unit, and a guide member driving.

切断手段８は、図４（ａ）のように押え面１１６が貼付動作部として機能している状態から図４（ｂ）のように押え面１１６が成形ドラム４の外周面４ｆより離されて先端縁部１１７が成形ドラム４の外周面４ｆに近づく切断動作状態に設定された当該先端縁部１１７と、先端縁部１１７を切断動作状態に維持するガイド部材駆動手段１０１と、ガイド部材駆動手段１０１を制御する制御手段１０と、先端縁部１１７で進行方向が変更されたライナー２５を巻き取る巻取手段９とを備えて構成される。   In the cutting means 8, the pressing surface 116 is separated from the outer peripheral surface 4f of the forming drum 4 as shown in FIG. 4B from the state where the pressing surface 116 functions as a sticking operation unit as shown in FIG. The leading edge 117 that is set in a cutting operation state in which the leading edge 117 approaches the outer peripheral surface 4f of the molding drum 4, a guide member driving unit 101 that maintains the leading edge 117 in the cutting operation, and a guide member driving unit The control means 10 which controls 101, and the winding means 9 which winds up the liner 25 by which the advancing direction was changed by the front-end | tip edge part 117 are comprised.

言い換えれば、ガイド部材駆動手段１０１は、ガイド部材１００をゴム部材貼付動作状態とゴム部材切断動作状態とに設定する。
ゴム部材貼付動作状態では、図４（ａ）に示すように、押え面１１６が例えば成形ドラム４の外周面４ｆの接線と所定間隔隔てて平行に位置される水平面を形成し、ガイド面１１１が水平な押え面１１６の一端縁（終端縁１１３）から上方に傾斜する傾斜面を形成するようにガイド部材１００の姿勢が設定される。上記所定間隔は、ゴム部材２１の厚さ寸法ａとライナー２５の厚さ寸法ｂとを合わせた寸法ｃと略同じ間隔か、寸法ｃよりも若干小さい間隔に設定される。
ゴム部材切断動作状態では、ゴム部材貼付動作状態から、図４（ｂ）に示すように、押え面１１６が成形ドラム４の外周面４ｆより離れてかつ先端縁部１１７が成形ドラム４の外周面４ｆに近づくようにガイド部材１００の姿勢が設定される。 In other words, the guide member driving means 101 sets the guide member 100 to the rubber member sticking operation state and the rubber member cutting operation state.
In the rubber member pasting operation state, as shown in FIG. 4A, the pressing surface 116 forms a horizontal plane that is positioned parallel to the tangent line of the outer peripheral surface 4f of the molding drum 4, for example, and the guide surface 111 is The posture of the guide member 100 is set so as to form an inclined surface that inclines upward from one end edge (terminal edge 113) of the horizontal pressing surface 116. The predetermined interval is set to be approximately the same as the dimension c obtained by adding the thickness dimension a of the rubber member 21 and the thickness dimension b of the liner 25 or slightly smaller than the dimension c.
In the rubber member cutting operation state, from the rubber member sticking operation state, as shown in FIG. 4B, the pressing surface 116 is separated from the outer peripheral surface 4 f of the molding drum 4 and the leading edge 117 is the outer peripheral surface of the molding drum 4. The posture of the guide member 100 is set so as to approach 4f.

次に貼付装置１の動作について説明する。
まず、初期設定を行う。初期設定は、例えば、ゴム部材２１の一方の帯面２３に貼り付けられるライナー２５を軸３１に巻かれたゴム部材２１の巻出端２１ｔ（図１参照）より延長させて設けておき、この延長したライナー２５の延長端側を導入ガイドローラー１１２とガイド面１１１との間に通し、さらにヘッドの先端縁部１１７を経由させて軸９１に取付ける。そして、軸９１を回転させてライナー２５を巻き取るとともに軸３１を回転させてゴム部材２１の巻出端２１ｔを導入ガイドローラー１１２とガイド面１１１との間に通して成形ドラム４の外周面４ｆの上に位置させる。
次にゴム部材貼付動作を行う。ゴム部材貼付動作は、ガイド部材駆動手段１０１によりガイド部材１００をゴム部材貼付動作状態に設定した後、一方の帯面２３にライナー２５が貼り付けられたゴム部材２１を巻き出す方向に軸３１を回転させ、ライナー２５を巻き取る方向に軸９１を回転させ、かつ、巻き出されたゴム部材２１を巻取る方向に成形ドラム４を例えば１回転させる。これにより、押え面１１６でゴム部材２１が成形ドラム４の外周面４ｆの方向に押し付けられてゴム部材２１が成形ドラム４の外周面４ｆの上に貼り付けられていくとともに、ライナー２５は先端縁部１１７で折り返されて軸９１に巻き取られる。
成形ドラム４を１回転させた後、ゴム部材切断動作を行う。ゴム部材切断動作は、ガイド部材駆動手段１０１によりガイド部材１００を図４（ｂ）のようにゴム部材切断動作状態に設定する。これにより、ライナー２５を挟んで先端縁部１１７と向かい合うゴム部材２１に応力が集中してゴム部材２１が切断される（図４（ｂ）参照）。尚、ゴム部材切断動作時においては、ガイド部材１００の姿勢変更に対応して、制御手段１０が回転駆動機構９２を制御してライナー２５を巻き戻す方向に軸９１を回転させる。
ゴム部材２１の貼付け始端と切断端との間の隙間Ｈは、ガイド部材１００又は手動によりジョイントされる。例えば、ガイド部材１００をゴム部材切断動作状態に維持したまま成形ドラム４を回転させることにより、ガイド部材１００の先端縁部１１７側が生ゴム状態のゴム部材２１の表面側と接触するのでステッチング動作が行われて隙間Ｈがジョイントされる。
その後、成形ドラム４の外周面４ｆにおける回転中心軸４１に沿った方向にずれた位置にゴム部材２１を貼付ける場合には、成形ドラム４を回転中心軸４１に沿った方向に移動させたり、あるいは、台車１５を成形ドラム４を回転中心軸４１に沿った方向に移動させてゴム部材貼付動作を行えばよい。 Next, operation | movement of the sticking apparatus 1 is demonstrated.
First, initial setting is performed. In the initial setting, for example, a liner 25 attached to one band surface 23 of the rubber member 21 is provided extending from the unwinding end 21t (see FIG. 1) of the rubber member 21 wound around the shaft 31, The extended end side of the extended liner 25 is passed between the introduction guide roller 112 and the guide surface 111, and is further attached to the shaft 91 via the tip edge portion 117 of the head. Then, the shaft 91 is rotated to wind the liner 25 and the shaft 31 is rotated to pass the unwinding end 21 t of the rubber member 21 between the introduction guide roller 112 and the guide surface 111, and the outer peripheral surface 4 f of the molding drum 4. Position on top of.
Next, a rubber member sticking operation is performed. In the rubber member sticking operation, after the guide member 100 is set to the rubber member sticking operation state by the guide member driving means 101, the shaft 31 is moved in the direction of unwinding the rubber member 21 having the liner 25 stuck on one of the belt surfaces 23. The shaft 91 is rotated in the direction in which the liner 25 is wound, and the molding drum 4 is rotated, for example, once in the direction in which the rubber member 21 that has been unwound is wound. As a result, the rubber member 21 is pressed by the pressing surface 116 in the direction of the outer peripheral surface 4f of the molding drum 4 so that the rubber member 21 is stuck on the outer peripheral surface 4f of the molding drum 4, and the liner 25 has a leading edge. It is folded by the portion 117 and wound on the shaft 91.
After the molding drum 4 is rotated once, a rubber member cutting operation is performed. In the rubber member cutting operation, the guide member driving means 101 sets the guide member 100 to the rubber member cutting operation state as shown in FIG. As a result, stress concentrates on the rubber member 21 facing the front end edge portion 117 with the liner 25 interposed therebetween, and the rubber member 21 is cut (see FIG. 4B). During the rubber member cutting operation, the control means 10 controls the rotation drive mechanism 92 to rotate the shaft 91 in the direction to rewind the liner 25 in response to the change in the posture of the guide member 100.
The gap H between the sticking start end and the cut end of the rubber member 21 is jointed by the guide member 100 or manually. For example, by rotating the molding drum 4 while the guide member 100 is maintained in the rubber member cutting operation state, the leading edge portion 117 side of the guide member 100 comes into contact with the surface side of the rubber member 21 in the raw rubber state, so that the stitching operation is performed. The gap H is jointed.
Then, when sticking the rubber member 21 at a position shifted in the direction along the rotation center axis 41 on the outer peripheral surface 4f of the molding drum 4, the molding drum 4 is moved in the direction along the rotation center axis 41, Alternatively, the rubber member pasting operation may be performed by moving the cart 15 in the direction along the rotation center axis 41 of the molding drum 4.

貼付装置１を用いたタイヤ成形用ゴム部材の貼付方法は、軸３１に巻かれた場合に帯面と帯面とが接触しないように帯状のタイヤ成形用ゴム部材２１の一方の帯面２３にライナー２５（面接触防止部材）が剥離可能に取付けられて軸３１に巻かれた帯状部材２を軸３１から巻出す巻出工程と、巻出された帯状部材２におけるゴム部材２１の他方の帯面２４を回転する成形ドラム４の外周面４ｆの上に貼り付ける貼付工程と、貼付工程後にゴム部材２１の一方の帯面２３よりライナー２５を剥離させる剥離工程と、回転する成形ドラム４の外周面４ｆの上に貼付工程によりゴム部材２１を所定の長さ分だけ貼り付けた後にゴム部材２１を切断する切断工程と、を備え、上記貼付工程と剥離工程と切断工程とがガイド部材１００により行われる。   The tire molding rubber member affixing method using the affixing device 1 is applied to one belt surface 23 of the belt-shaped tire molding rubber member 21 so that the belt surface does not contact the belt surface when wound around the shaft 31. An unwinding step of unwinding the strip-shaped member 2 on which the liner 25 (surface contact preventing member) is releasably attached and wound on the shaft 31 from the shaft 31, and the other band of the rubber member 21 in the unrolled strip-shaped member 2 An affixing step for affixing the surface 24 onto the outer peripheral surface 4f of the rotating molding drum 4, a peeling step for exfoliating the liner 25 from one band surface 23 of the rubber member 21 after the affixing step, and an outer periphery of the rotating molding drum 4 A cutting step of cutting the rubber member 21 after the rubber member 21 is pasted by a predetermined length on the surface 4f by a sticking step, and the sticking step, the peeling step, and the cutting step are performed by the guide member 100. Done.

貼付装置１によれば、貼付動作部として機能する押え面１１６と剥離動作部として機能する先端縁部１１７とを有したガイド部材１００を備え、ゴム部材２１を成形ドラム４の外周面４ｆの上に貼り付けた後に、ゴム部材２１の一方の帯面２３よりライナー２５を剥離させるので、ゴム部材２１が巻出されて成形ドラム４の外周面４ｆの上に貼付けられるまでの間はゴム部材２１の一方の帯面２３にライナー２５が取付けられた状態で搬送されるため、ゴム部材２１の伸びを抑制できる。
また、切断動作部として機能する先端縁部１１７を有したガイド部材１００を備え、回転する成形ドラム４の外周面４ｆの上にゴム部材２１を所定の長さ分だけ貼り付けた後にゴム部材２１を切断するので、切断動作の自動化が図れるとともに、成形ドラム４の外周面４ｆの上でゴム部材２１を切断することができることから、成形ドラム４の外周面４ｆの上に貼り付けるゴム部材２１の長さ寸法の精度が向上する。
また、ゴム部材切断動作の後にゴム部材貼付動作に移行する際には、巻取手段９で巻き取られているライナー２５にゴム部材２１が貼り付いている状態となるので、ガイド部材１００をゴム部材切断動作からゴム部材貼付動作に移行した際にゴム部材２１の切断面側（先端側）が垂れ下がるようなことがなく、ゴム部材２１の切断面（先端）が成形ドラム４の外周面４ｆの上の貼付始端位置に正確に位置付けされるようになる。
また、ガイド部材１００により貼付動作と切断動作と剥離動作とを行うことができ、ガイド部材１００を制御することによりこれらすべての動作を制御できるので、制御が容易となる。 According to the sticking device 1, the guide member 100 having the pressing surface 116 functioning as the sticking operation part and the tip edge part 117 functioning as the peeling action part is provided, and the rubber member 21 is placed on the outer peripheral surface 4 f of the molding drum 4. Since the liner 25 is peeled off from one band surface 23 of the rubber member 21, the rubber member 21 is unwound until the rubber member 21 is unwound and pasted onto the outer peripheral surface 4f of the molding drum 4. Since one of the belt surfaces 23 is conveyed with the liner 25 attached thereto, the rubber member 21 can be prevented from stretching.
Further, the guide member 100 having the tip edge portion 117 functioning as a cutting operation portion is provided, and the rubber member 21 is pasted on the outer peripheral surface 4f of the rotating molding drum 4 by a predetermined length, and then the rubber member 21 is attached. Therefore, the cutting operation can be automated, and the rubber member 21 can be cut on the outer peripheral surface 4f of the molding drum 4. Therefore, the rubber member 21 to be pasted on the outer peripheral surface 4f of the molding drum 4 can be cut. The accuracy of the length dimension is improved.
When the rubber member cutting operation is performed after the rubber member cutting operation, the rubber member 21 is stuck to the liner 25 wound by the winding means 9, so that the guide member 100 is made of rubber. When the transition is made from the member cutting operation to the rubber member attaching operation, the cut surface side (tip side) of the rubber member 21 does not hang down, and the cut surface (tip end) of the rubber member 21 is not in contact with the outer peripheral surface 4f of the molding drum 4. It comes to be accurately positioned at the upper sticking start position.
Further, the sticking operation, the cutting operation, and the peeling operation can be performed by the guide member 100, and since all these operations can be controlled by controlling the guide member 100, the control becomes easy.

従来、例えば成形ドラムを回転させながら成形ドラムの外周面の上にゴム部材を手作業で貼り付けた後に切断する作業を行っている場合があったが、本発明の貼付装置１を用いれば、このような手作業を自動化できる。   Conventionally, for example, there has been a case where the rubber member is manually pasted on the outer peripheral surface of the molding drum while rotating the molding drum and then cut, but if the pasting device 1 of the present invention is used, Such manual work can be automated.

尚、ガイド部材１００の先端縁部１１７の形状を鋭利な形状とすればゴム部材２１が切断され易くなるが、ゴム部材切断動作時においてライナー２５が切断されないように、ライナー２５の材質とガイド部材１００の先端縁部１１７の形状とを決定すればよい。例えば、ライナー２５の強度が弱い場合には、先端縁部１１７をあまり鋭利な形状にしないようにし、ライナー２５の強度が十分にある場合には、先端縁部１１７を鋭利な形状にする。
また、ゴム部材２１の他方の帯面２４を成形ドラム４の外周面４ｆの上に貼り付けた後にゴム部材２１の一方の帯面２３よりライナー２５を剥離させる機能を有した剥離動作部をガイド部材１００に設けたが、剥離動作部をガイド部材１００とは別に設けてもよい。 Note that the rubber member 21 can be easily cut when the tip edge 117 of the guide member 100 is sharp, but the material of the liner 25 and the guide member are not cut so that the liner 25 is not cut during the rubber member cutting operation. What is necessary is just to determine the shape of 100 front-end | tip edge parts 117. FIG. For example, when the strength of the liner 25 is weak, the tip edge portion 117 is not made so sharp, and when the liner 25 is sufficiently strong, the tip edge portion 117 is made sharp.
Further, after the other band surface 24 of the rubber member 21 is attached to the outer peripheral surface 4f of the molding drum 4, a peeling operation unit having a function of peeling the liner 25 from the one band surface 23 of the rubber member 21 is guided. Although provided on the member 100, the peeling operation unit may be provided separately from the guide member 100.

また、各軸３１；４１；９１を連動するように回転させてもよい。例えば、回転中心軸４１の回転力を伝達機構を介して軸３１；９１に伝達して軸３１；９１を回転させてもよい。この場合、各軸３１；４１；９１の回転速度制御を不要とできる。また、軸３１の回転と軸９１の回転とを伝達機構を介して連動させてもよい。つまり、文房具の修正インク貼付装置のように構成してもよい。   Moreover, you may rotate so that each axis | shaft 31; 41; 91 may interlock | cooperate. For example, the rotational force of the rotation center shaft 41 may be transmitted to the shaft 31; 91 via a transmission mechanism to rotate the shaft 31; In this case, the rotational speed control of the shafts 31; 41; 91 can be made unnecessary. Further, the rotation of the shaft 31 and the rotation of the shaft 91 may be linked via a transmission mechanism. That is, you may comprise like the correction ink sticking apparatus of a stationery.
