Description

本発明は、帯状部材の前端と後端を接合して環状部材を成形する環状部材の成形装置及び成形方法に関する。   The present invention relates to an annular member forming apparatus and a forming method for forming an annular member by joining a front end and a rear end of a belt-like member.

タイヤの製造には複数のタイヤ構成部材が用いられており、複数のタイヤ構成部材を組わせることで、グリーンタイヤが製造される。また、グリーンタイヤが加硫されて、タイヤが製造される。このグリーンタイヤの製造時には、各種の帯状部材を環状に成形するため、円筒状のドラムが使用されている。   A plurality of tire constituent members are used for manufacturing a tire, and a green tire is manufactured by combining a plurality of tire constituent members. Further, the tire is manufactured by vulcanizing the green tire. At the time of manufacturing this green tire, a cylindrical drum is used to form various belt-like members in an annular shape.

図１２は、従来の環状部材の成形装置１００を示す図であり、図１２Ａは、一般的な環状部材の成形装置１００の例を示している。また、図１２Ｂ〜図１２Ｄは、環状部材の成形装置１００の一部であるドラム１０１を示している。
図示のように、帯状部材Ｈは、未加硫ゴム等により形成された後、所定長さに切断されて、回転するドラム１０１に巻き付けられる。環状部材の成形装置１００は、ドラム１０１に巻き付けた帯状部材Ｈの前端Ｈ１と後端Ｈ２を接合して、環状部材Ｋを成形する。 FIG. 12 is a view showing a conventional annular member forming apparatus 100, and FIG. 12A shows an example of a general annular member forming apparatus 100. FIG. 12B to 12D show a drum 101 that is a part of the annular member forming apparatus 100.
As shown in the figure, the belt-shaped member H is formed of unvulcanized rubber or the like, then cut into a predetermined length and wound around a rotating drum 101. The annular member forming apparatus 100 joins the front end H1 and the rear end H2 of the belt-like member H wound around the drum 101 to form the annular member K.

ところが、帯状部材Ｈの切断後には、ゴムの収縮により、帯状部材Ｈの長さが変化して、帯状部材Ｈの長さが一定にならないことがある。また、帯状部材Ｈの前端Ｈ１と後端Ｈ２がドラム１０１に配置されるときに、前端Ｈ１の位置と後端Ｈ２の位置がずれることがある。そのため、前端Ｈ１と後端Ｈ２の接合の状態を常に一定に維持するのは難しい。帯状部材Ｈの接合量にばらつきが生じた場合には（図１２Ｂ〜図１２Ｄ参照）、作業者が前端Ｈ１と後端Ｈ２の接合を手直しする必要があり、環状部材Ｋの成形のための手間が増加する。従って、従来の環状部材の成形装置１００に関して、前端Ｈ１と後端Ｈ２の接合の精度を向上させて、環状部材Ｋをより精度よく成形する観点から、改良の余地がある。   However, after the band-shaped member H is cut, the length of the band-shaped member H may change due to the shrinkage of the rubber, and the length of the band-shaped member H may not be constant. Further, when the front end H1 and the rear end H2 of the belt-like member H are arranged on the drum 101, the position of the front end H1 and the position of the rear end H2 may be shifted. Therefore, it is difficult to always keep the joining state of the front end H1 and the rear end H2 constant. When the joining amount of the belt-like member H varies (see FIGS. 12B to 12D), it is necessary for the operator to rework the joining of the front end H1 and the rear end H2, and time and effort for forming the annular member K is required. Will increase. Therefore, with respect to the conventional annular member molding apparatus 100, there is room for improvement from the viewpoint of improving the accuracy of joining the front end H1 and the rear end H2 and molding the annular member K more accurately.

これに対し、従来、帯状部材の測定長さに基づいてドラム直径を変化させることで、帯状部材の接合量を調節する帯状部材の巻き付け装置が知られている（特許文献１参照）。
しかしながら、特許文献１に記載された従来の巻き付け装置では、帯状部材の長さの測定後に、帯状部材の長さが変化する虞がある。帯状部材の長さが変化した場合には、帯状部材の前端と後端の接合の精度に影響が生じる。また、ドラム直径の変化に伴い、環状部材の直径が変化するため、成形後の環状部材の精度（寸法精度）が低下する虞もある。 On the other hand, a belt-shaped member winding device that adjusts the joining amount of the belt-shaped member by changing the drum diameter based on the measured length of the belt-shaped member has been known (see Patent Document 1).
However, in the conventional winding device described in Patent Document 1, there is a possibility that the length of the band-shaped member may change after the length of the band-shaped member is measured. When the length of the band-shaped member changes, the accuracy of joining the front end and the rear end of the band-shaped member is affected. In addition, since the diameter of the annular member changes as the drum diameter changes, the accuracy (dimensional accuracy) of the annular member after molding may be reduced.

配置装置２０により、帯状部材Ｈの前端Ｈ１がドラム２に貼り付けられた後、前端Ｈ１の固定手段である固定装置３０により、帯状部材Ｈの前端Ｈ１がドラム２に固定される。その状態で、帯状部材Ｈが回転するドラム２に巻き付けられる。帯状部材Ｈのドラム２への巻き付けが完了したときに、配置装置２０により、帯状部材Ｈの後端Ｈ２がドラム２に貼り付けられる。その後、帯状部材Ｈの接合手段である接合装置４０により、前端Ｈ１と後端Ｈ２が接合される。   After the front end H1 of the belt-shaped member H is attached to the drum 2 by the placement device 20, the front end H1 of the belt-shaped member H is fixed to the drum 2 by the fixing device 30 that is a fixing means for the front end H1. In this state, the belt-shaped member H is wound around the rotating drum 2. When the winding of the belt-shaped member H around the drum 2 is completed, the rear end H2 of the belt-shaped member H is attached to the drum 2 by the placement device 20. Thereafter, the front end H <b> 1 and the rear end H <b> 2 are joined by the joining device 40 which is a joining means of the belt-like member H.

図２は、本実施形態の帯状部材Ｈの配置装置２０の一部を示す側面図であり、固定装置３０、接合装置４０、及び、検出装置５も示している。
図示のように、固定装置３０は、配置装置２０の貼付装置５０に取り付けられ、接合装置４０と検出装置５は、配置装置２０の移動部２３に取り付けられている。そのため、固定装置３０、接合装置４０、及び、検出装置５は、配置装置２０の移動装置２１により、貼付装置５０とともに移動する。従って、移動装置２１は、貼付装置５０の移動手段であり、かつ、固定装置３０、接合装置４０、及び、検出装置５の移動手段でもある。貼付装置５０、固定装置３０、接合装置４０、及び、検出装置５は、移動装置２１により移動する移動ユニット８であり、帯状部材Ｈの供給方向Ｖと供給方向Ｖの反対方向に同時に移動する。従って、貼付装置５０が移動装置２１により移動するときには、貼付装置５０を含む移動ユニット８が移動装置２１により一体に移動する。 FIG. 2 is a side view showing a part of the belt-shaped member H placement device 20 of the present embodiment, and also shows the fixing device 30, the joining device 40, and the detection device 5.
As illustrated, the fixing device 30 is attached to the sticking device 50 of the placement device 20, and the joining device 40 and the detection device 5 are attached to the moving unit 23 of the placement device 20. Therefore, the fixing device 30, the joining device 40, and the detection device 5 are moved together with the sticking device 50 by the moving device 21 of the placement device 20. Therefore, the moving device 21 is a moving unit of the sticking device 50 and also a moving unit of the fixing device 30, the joining device 40, and the detecting device 5. The sticking device 50, the fixing device 30, the joining device 40, and the detection device 5 are moving units 8 that are moved by the moving device 21, and simultaneously move in the direction opposite to the supply direction V and the supply direction V of the band-shaped member H. Therefore, when the sticking device 50 moves by the moving device 21, the moving unit 8 including the sticking device 50 moves integrally by the moving device 21.

固定装置３０は、帯状部材Ｈを押さえる押さえ部材３１と、押さえ部材３１の着脱装置３２を有する。押さえ部材３１は、着脱装置３２の保持部材３３により保持されて、貼付装置５０と帯状部材Ｈ（ドラム２）の間に配置される。着脱装置３２は、移動機構（図示せず）により保持部材３３を移動させて、保持部材３３による押さえ部材３１の保持と、保持部材３３による押さえ部材３１の保持の解除を行う。また、保持部材３３の移動により、着脱装置３２は、押さえ部材３１のドラム２への取り付けと、押さえ部材３１のドラム２からの取り外しとを行う。   The fixing device 30 includes a pressing member 31 that presses the belt-shaped member H and an attaching / detaching device 32 for the pressing member 31. The pressing member 31 is held by the holding member 33 of the attaching / detaching device 32 and is disposed between the sticking device 50 and the belt-like member H (drum 2). The attachment / detachment device 32 moves the holding member 33 by a moving mechanism (not shown) to release the holding member 31 by the holding member 33 and release the holding member 31 by the holding member 33. Further, by the movement of the holding member 33, the attachment / detachment device 32 attaches the pressing member 31 to the drum 2 and removes the pressing member 31 from the drum 2.

帯状部材Ｈの前端Ｈ１を固定するときに、着脱装置３２により、固定装置３０は、押さえ部材３１をドラム２に取り付けて、押さえ部材３１の保持を解除する。押さえ部材３１は、例えば、内部の磁石によりドラム２に付着して、ドラム２に固定される。ドラム２への取り付けに伴い、押さえ部材３１は、帯状部材Ｈをドラム２に押さえる。押さえ部材３１により、帯状部材Ｈが押さえ部材３１とドラム２に挟まれて、帯状部材Ｈの前端Ｈ１が押さえ部材３１によりドラム２に固定される。帯状部材Ｈの前端Ｈ１の固定を解除するときには、着脱装置３２により、固定装置３０は、押さえ部材３１を保持して、押さえ部材３１をドラム２から取り外す。これにより、押さえ部材３１が固定装置３０に回収される。   When fixing the front end H <b> 1 of the belt-like member H, the fixing device 30 attaches the pressing member 31 to the drum 2 by the attaching / detaching device 32 and releases the holding of the pressing member 31. The pressing member 31 is fixed to the drum 2 by being attached to the drum 2 by an internal magnet, for example. Along with the attachment to the drum 2, the pressing member 31 presses the belt-shaped member H against the drum 2. The band-shaped member H is sandwiched between the pressing member 31 and the drum 2 by the pressing member 31, and the front end H <b> 1 of the band-shaped member H is fixed to the drum 2 by the pressing member 31. When the fixing of the front end H <b> 1 of the belt-shaped member H is released, the fixing device 30 holds the pressing member 31 and removes the pressing member 31 from the drum 2 by the attaching / detaching device 32. Thereby, the pressing member 31 is collected by the fixing device 30.

接合装置４０は、帯状部材Ｈを加圧する加圧部材４１と、加圧部材４１の移動機構４２を有する。移動機構４２は、ピストン・シリンダ機構であり、加圧部材４１を移動させて、帯状部材Ｈに加圧部材４１を接触させる。帯状部材Ｈの前端Ｈ１と後端Ｈ２をドラム２の外周で重ねた後、移動機構４２により、加圧部材４１が、前端Ｈ１と後端Ｈ２の重なる部分に押し付けられる。加圧部材４１により、接合装置４０は、前端Ｈ１と後端Ｈ２の重なる部分を加圧して、帯状部材Ｈの前端Ｈ１と後端Ｈを接合する。   The bonding apparatus 40 includes a pressure member 41 that pressurizes the belt-shaped member H and a moving mechanism 42 for the pressure member 41. The moving mechanism 42 is a piston / cylinder mechanism, and moves the pressure member 41 to bring the pressure member 41 into contact with the belt-shaped member H. After the front end H1 and the rear end H2 of the belt-like member H are overlapped on the outer periphery of the drum 2, the pressing member 41 is pressed against the overlapping portion of the front end H1 and the rear end H2 by the moving mechanism. By the pressing member 41, the joining device 40 pressurizes a portion where the front end H <b> 1 and the rear end H <b> 2 overlap to join the front end H <b> 1 and the rear end H of the band-shaped member H.

配置装置２０の貼付装置５０は、帯状部材Ｈの前端Ｈ１と後端Ｈ２を保持する保持部５１と、保持部５１の移動機構５２を有する。ここでは、保持部５１は、帯状部材Ｈの幅方向の全体を吸着する吸着手段を有し、吸着により、帯状部材Ｈの前端Ｈ１と後端Ｈ２の幅方向の全体を保持する。移動機構５２は、ピストン・シリンダ機構であり、移動機構５２により、保持部５１は、帯状部材Ｈから離れた位置（図２に示す位置）と、帯状部材Ｈに接触する位置とに移動する。その際、保持部５１は、押さえ部材３１に形成された通過孔３４を通過し、押さえ部材３１の一方側から他方側まで移動する。   The sticking device 50 of the placement device 20 includes a holding portion 51 that holds the front end H1 and the rear end H2 of the belt-like member H, and a moving mechanism 52 of the holding portion 51. Here, the holding part 51 has an adsorbing unit that adsorbs the entire band-shaped member H in the width direction, and holds the entire width of the front end H1 and the rear end H2 of the band-shaped member H by adsorption. The moving mechanism 52 is a piston / cylinder mechanism, and the holding mechanism 51 is moved by the moving mechanism 52 to a position away from the band-shaped member H (a position shown in FIG. 2) and a position in contact with the band-shaped member H. At that time, the holding portion 51 passes through the passage hole 34 formed in the pressing member 31 and moves from one side of the pressing member 31 to the other side.

貼付装置５０は、保持部５１を帯状部材Ｈの前端Ｈ１と後端Ｈ２に接触させて、保持部５１により、帯状部材Ｈの前端Ｈ１と後端Ｈ２を保持する。また、貼付装置５０は、移動機構５２により保持部５１を移動させて、保持部５１により保持された帯状部材Ｈの前端Ｈ１と後端Ｈ２をドラム２に押し付ける。これにより、帯状部材Ｈの前端Ｈ１と後端Ｈ２がドラム２に貼り付けられる。また、前端Ｈ１と後端Ｈ２の貼り付け後に、貼付装置５０は、保持部５１による帯状部材Ｈの前端Ｈ１と後端Ｈ２の保持を解除し、移動機構５２により、保持部５１を帯状部材Ｈから離す。このように、貼付装置５０は、帯状部材Ｈの前端Ｈ１の貼り付けを行う前端貼付手段であり、かつ、帯状部材Ｈの後端Ｈ２の貼り付けを行う後端貼付手段である。   The sticking device 50 brings the holding portion 51 into contact with the front end H1 and the rear end H2 of the belt-like member H, and holds the front end H1 and the rear end H2 of the belt-like member H by the holding portion 51. Further, the sticking device 50 moves the holding portion 51 by the moving mechanism 52 and presses the front end H1 and the rear end H2 of the belt-like member H held by the holding portion 51 against the drum 2. As a result, the front end H1 and the rear end H2 of the belt-shaped member H are attached to the drum 2. In addition, after pasting the front end H1 and the rear end H2, the pasting device 50 releases the holding of the front end H1 and the rear end H2 of the band-shaped member H by the holding unit 51, and moves the holding unit 51 to the band-shaped member H by the moving mechanism 52. Move away from. Thus, the sticking device 50 is a front end sticking means for sticking the front end H1 of the belt-like member H, and a rear end sticking means for sticking the rear end H2 of the belt-like member H.

この成形装置１では（図１参照）、前端貼付手段と後端貼付手段は、帯状部材Ｈの前端Ｈ１と後端Ｈ２のそれぞれを保持して移動する１つの貼付装置５０である。貼付装置５０は、移動装置２１により移動して、保持部５１により保持した帯状部材Ｈの前端Ｈ１と後端Ｈ２のそれぞれを移動させる。成形装置１は、貼付装置５０を移動させて、帯状部材Ｈをドラム２に巻き付け、ドラム２により環状部材Ｋを成形する。以下、成形装置１による環状部材Ｋの成形手順について説明する。   In this molding apparatus 1 (see FIG. 1), the front end pasting means and the rear end pasting means are one pasting apparatus 50 that moves while holding the front end H1 and the rear end H2 of the belt-like member H. The sticking device 50 is moved by the moving device 21 and moves each of the front end H1 and the rear end H2 of the belt-like member H held by the holding portion 51. The forming device 1 moves the sticking device 50 to wind the belt-like member H around the drum 2, and the annular member K is formed by the drum 2. Hereinafter, a procedure for forming the annular member K by the forming apparatus 1 will be described.

図３〜図１０は、本実施形態の環状部材Ｋの成形手順を示す側面図である。図１１は、環状部材Ｋの成形の各段階における制御装置７による速度制御を示すグラフであり、成形装置１の各部の速度変化を示している。また、図１１に示す速度は、供給装置１０による帯状部材Ｈの供給速度、貼付装置５０の移動速度、又は、ドラム２の周速度である。これら３つの速度は、それぞれ環状部材Ｋの成形中に制御装置７により変更される。   3-10 is a side view which shows the shaping | molding procedure of the annular member K of this embodiment. FIG. 11 is a graph showing the speed control by the control device 7 at each stage of forming the annular member K, and shows the speed change of each part of the forming device 1. Moreover, the speed shown in FIG. 11 is the supply speed of the band-shaped member H by the supply apparatus 10, the moving speed of the sticking apparatus 50, or the peripheral speed of the drum 2. These three speeds are changed by the control device 7 during the molding of the annular member K.

図示のように、成形装置１は、移動装置２１により、移動ユニット８（貼付装置５０、固定装置３０、接合装置４０、及び、検出装置５）を移動させて、検出装置５により、帯状部材Ｈの前端Ｈ１を検出する（図３参照）。帯状部材Ｈの前端Ｈ１は、供給装置１０による帯状部材Ｈの供給経路中に位置し、保持装置６により保持されている。次に、貼付装置５０が、移動装置２１により、検出装置５により検出された帯状部材Ｈの前端Ｈ１の位置に移動して、帯状部材Ｈの前端Ｈ１を保持する。その状態で、保持装置６による前端Ｈ１の保持を解除し、移動装置２１により、移動ユニット８をドラム２に向かって移動させる（図４参照）。これにより、移動装置２１は、前端Ｈ１を保持する貼付装置５０をドラム２に向かって移動させて、帯状部材Ｈの前端Ｈ１の貼り付けを行う貼付位置（第１貼付位置Ｐ１）に貼付装置５０を配置する（図５参照）。   As shown in the figure, the molding device 1 moves the moving unit 8 (the pasting device 50, the fixing device 30, the joining device 40, and the detecting device 5) by the moving device 21, and the detecting device 5 moves the belt-like member H. Is detected (see FIG. 3). The front end H <b> 1 of the belt-like member H is located in the supply path of the belt-like member H by the feeding device 10 and is held by the holding device 6. Next, the sticking device 50 is moved by the moving device 21 to the position of the front end H1 of the belt-like member H detected by the detection device 5, and holds the front end H1 of the belt-like member H. In this state, the holding of the front end H1 by the holding device 6 is released, and the moving unit 21 is moved toward the drum 2 by the moving device 21 (see FIG. 4). As a result, the moving device 21 moves the sticking device 50 holding the front end H1 toward the drum 2, and sticks the sticking device 50 to the sticking position (first sticking position P1) where the front end H1 of the belt-like member H is stuck. (See FIG. 5).

貼付装置５０の移動時には、ガイド部１２の可動部１３を移動させて、供給装置１０のガイド部１２を伸ばす。また、貼付装置５０の移動に合わせて、供給装置１０は、搬送装置１１により帯状部材Ｈを搬送して、帯状部材Ｈをドラム２に供給する。貼付装置５０は、供給装置１０から供給される帯状部材Ｈの前端Ｈ１を保持して、ドラム２に向かって前端Ｈ１を移動させる。続いて、移動装置２１により、貼付装置５０は、第１貼付位置Ｐ１まで移動して、第１貼付位置Ｐ１に配置される。貼付装置５０の第１貼付位置Ｐ１への配置と同時に、供給装置１０は、搬送装置１１による帯状部材Ｈの搬送を停止して、帯状部材Ｈのドラム２への供給を中断する。その状態で、帯状部材Ｈの前端Ｈ１をドラム２に押し付けることで、貼付装置５０は、前端Ｈ１をドラム２の所定位置に貼り付けて配置する（図６参照）。その後、貼付装置５０は、帯状部材Ｈの前端Ｈ１の保持を解除する。   When the sticking device 50 is moved, the movable portion 13 of the guide portion 12 is moved to extend the guide portion 12 of the supply device 10. Further, in accordance with the movement of the sticking device 50, the supply device 10 transports the belt-shaped member H by the transport device 11 and supplies the belt-shaped member H to the drum 2. The sticking device 50 holds the front end H1 of the belt-like member H supplied from the supply device 10 and moves the front end H1 toward the drum 2. Subsequently, the sticking device 50 is moved to the first sticking position P1 by the moving device 21, and is arranged at the first sticking position P1. Simultaneously with the placement of the sticking device 50 at the first sticking position P1, the supply device 10 stops the transport of the belt-like member H by the transport device 11 and interrupts the supply of the belt-like member H to the drum 2. In this state, by pressing the front end H1 of the belt-like member H against the drum 2, the sticking device 50 places the front end H1 at a predetermined position on the drum 2 (see FIG. 6). Thereafter, the sticking device 50 releases the holding of the front end H1 of the belt-like member H.

このように、前端貼付手段である貼付装置５０により、帯状部材Ｈの前端Ｈ１を保持し、ドラム２に帯状部材Ｈの前端Ｈ１を貼り付ける。その際、制御装置７は、供給装置１０と移動装置２１を制御して、供給装置１０による帯状部材Ｈの供給速度（搬送速度）（図１１Ａの速度Ｓ１）と、移動装置２１による貼付装置５０の移動速度（前端Ｈ１の移動速度）（図１１Ａの速度Ｓ２）とを一致させる。供給装置１０と移動装置２１は、制御装置７の制御により同期して作動する。   In this manner, the front end H1 of the belt-like member H is held by the sticking device 50 as the front-end sticking means, and the front end H1 of the belt-like member H is stuck to the drum 2. At that time, the control device 7 controls the supply device 10 and the moving device 21 to supply the belt member H by the supply device 10 (feed speed) (speed S1 in FIG. 11A) and the sticking device 50 by the moving device 21. (The speed of movement of the front end H1) (speed S2 of FIG. 11A). The supply device 10 and the moving device 21 operate in synchronization under the control of the control device 7.

貼付装置５０により帯状部材Ｈの前端Ｈ１をドラム２に貼り付けた後、固定装置３０は、ドラム２に押さえ部材３１を取り付けて、押さえ部材３１により、ドラム２に貼り付けられた帯状部材Ｈの前端Ｈ１をドラム２に固定する。その際、押さえ部材３１は、前端Ｈ１の近傍で帯状部材Ｈを押さえる。帯状部材Ｈのドラム２への巻き付け中に、固定装置３０は、押さえ部材３１により、帯状部材Ｈの前端Ｈ１をドラム２に固定した状態に維持する。   After the front end H1 of the belt-like member H is stuck to the drum 2 by the sticking device 50, the fixing device 30 attaches the pressing member 31 to the drum 2, and the belt-like member H stuck to the drum 2 by the pressing member 31. The front end H1 is fixed to the drum 2. At that time, the pressing member 31 presses the belt-shaped member H in the vicinity of the front end H1. During the winding of the belt-shaped member H around the drum 2, the fixing device 30 maintains the front end H <b> 1 of the belt-shaped member H fixed to the drum 2 by the pressing member 31.

続いて、駆動装置３により、ドラム２を回転させて、帯状部材Ｈを前端Ｈ１からドラム２に巻き付ける（図７参照）。ドラム２の回転に合わせて、供給装置１０は、搬送装置１１により帯状部材Ｈを搬送して、帯状部材Ｈをドラム２に供給する。その際、制御装置７は、供給装置１０とドラム２の駆動装置３を制御して、供給装置１０による帯状部材Ｈの供給速度（図１１Ｂの速度Ｓ３）と、ドラム２の周速度（帯状部材Ｈの巻き付け速度）（図１１Ｂの速度Ｓ４）とを一致させる。供給装置１０と駆動装置３は、制御装置７の制御により同期して作動する。   Subsequently, the drum 2 is rotated by the driving device 3, and the belt-like member H is wound around the drum 2 from the front end H1 (see FIG. 7). In synchronization with the rotation of the drum 2, the supply device 10 transports the belt-shaped member H by the transport device 11 and supplies the belt-shaped member H to the drum 2. At that time, the control device 7 controls the supply device 10 and the driving device 3 of the drum 2 to supply the belt-like member H by the supply device 10 (speed S3 in FIG. 11B) and the peripheral speed of the drum 2 (band-like member). H winding speed) (speed S4 in FIG. 11B). The supply device 10 and the drive device 3 operate in synchronization under the control of the control device 7.

帯状部材Ｈの巻き付け中に、貼付装置５０は、移動装置２１により、切断装置４の位置まで移動する。また、帯状部材Ｈを前端Ｈ１から後端Ｈ２まで回転するドラム２に巻き付ける途中に、駆動装置３により、ドラム２の回転を停止して、帯状部材Ｈの巻き付けを中断する。ドラム２の回転停止と同時に、供給装置１０は、搬送装置１１による帯状部材Ｈの搬送を停止して、帯状部材Ｈのドラム２への供給を中断する。このように、駆動装置３は、帯状部材Ｈのドラム２への巻き付け途中に、ドラム２の回転を停止することで、供給装置１０から供給される帯状部材Ｈのドラム２への巻き付けを一旦中断する。   During winding of the belt-shaped member H, the sticking device 50 is moved to the position of the cutting device 4 by the moving device 21. Further, while the belt-like member H is wound around the drum 2 rotating from the front end H1 to the rear end H2, the driving device 3 stops the rotation of the drum 2 and interrupts the winding of the belt-like member H. Simultaneously with the rotation stop of the drum 2, the supply device 10 stops the conveyance of the belt-shaped member H by the conveyance device 11 and interrupts the supply of the belt-shaped member H to the drum 2. As described above, the driving device 3 temporarily stops the winding of the belt-shaped member H supplied from the supply device 10 to the drum 2 by stopping the rotation of the drum 2 during the winding of the belt-shaped member H to the drum 2. To do.

帯状部材Ｈの前端Ｈ１を貼り付けたドラム２の回転が停止した状態で、貼付装置５０は、切断装置４による切断前の帯状部材Ｈの後端Ｈ２を保持する。貼付装置５０により保持される帯状部材Ｈの後端Ｈ２は、切断装置４の切断により帯状部材Ｈの後端Ｈ２となる部分（後端予定部）である。ここでは、帯状部材Ｈがドラム２に所定長さ巻き付けられたときに、駆動装置３がドラム２の回転を停止し、駆動装置３により帯状部材Ｈの巻き付けを中断した状態で、貼付装置５０が切断前の帯状部材Ｈの後端Ｈ２を保持する。貼付装置５０により、前端Ｈ１がドラム２に貼り付けられた切断前の帯状部材Ｈの後端Ｈ２が保持される。   In a state where the rotation of the drum 2 to which the front end H1 of the belt-like member H is stuck is stopped, the sticking device 50 holds the rear end H2 of the belt-like member H before being cut by the cutting device 4. The rear end H2 of the belt-like member H held by the sticking device 50 is a portion (a planned rear end) that becomes the rear end H2 of the belt-like member H when the cutting device 4 is cut. Here, when the belt-shaped member H is wound around the drum 2 for a predetermined length, the driving device 3 stops the rotation of the drum 2, and the winding device 50 is stopped in a state where the winding of the belt-shaped member H is interrupted by the driving device 3. The rear end H2 of the strip-shaped member H before cutting is held. The affixing device 50 holds the rear end H2 of the band-shaped member H before cutting, in which the front end H1 is affixed to the drum 2.

帯状部材Ｈの巻き付けを中断した状態で、切断装置４により、貼付装置５０により後端Ｈ２が保持された帯状部材Ｈを、帯状部材Ｈのドラム２への巻き付け長さに切断する（図８参照）。これにより、切断装置４は、前端Ｈ１がドラム２に貼り付けられた帯状部材Ｈを巻き付け長さに切断する。帯状部材Ｈの巻き付け長さは、環状部材Ｋの周長と帯状部材Ｈの接合量とに基づいて算出される。制御装置７の制御により、前端Ｈ１から切断装置４による切断位置までの帯状部材Ｈの長さが巻き付け長さになったときに、帯状部材Ｈの巻き付けが中断され、保持装置６が次の帯状部材Ｈの前端Ｈ１を保持する。また、前の帯状部材Ｈの後端Ｈ２が貼付装置５０により保持されて、保持装置６により保持された部分と貼付装置５０により保持された部分の間で、帯状部材Ｈが切断装置４により切断される。   In a state where the winding of the belt-like member H is interrupted, the cutting device 4 cuts the belt-like member H whose rear end H2 is held by the sticking device 50 to the winding length of the belt-like member H around the drum 2 (see FIG. 8). ). Thereby, the cutting device 4 cut | disconnects the strip | belt-shaped member H by which the front end H1 was affixed on the drum 2 to winding length. The winding length of the belt-like member H is calculated based on the circumferential length of the annular member K and the joining amount of the belt-like member H. When the length of the belt-like member H from the front end H1 to the cutting position by the cutting device 4 becomes the winding length by the control of the control device 7, the winding of the belt-like member H is interrupted, and the holding device 6 is moved to the next belt-like shape. The front end H1 of the member H is held. In addition, the rear end H2 of the front belt-like member H is held by the sticking device 50, and the belt-like member H is cut by the cutting device 4 between the portion held by the holding device 6 and the portion held by the sticking device 50. Is done.

切断装置４による帯状部材Ｈの切断後に、駆動装置３により、ドラム２を回転させて、帯状部材Ｈのドラム２への巻き付けを再開し、切断後の帯状部材Ｈを後端Ｈ２まで回転するドラム２に巻き付ける。帯状部材Ｈは、ガイド部１２によりガイドされて、ドラム２に供給される。また、切断後の帯状部材Ｈのドラム２への巻き付けに合わせて、移動装置２１は、帯状部材Ｈの後端Ｈ２を保持する貼付装置５０を回転するドラム２に向かって移動させる（図９参照）。貼付装置５０により、帯状部材Ｈの巻き付けに合わせて、帯状部材Ｈの後端Ｈ２がドラム２に向かって移動する。続いて、移動装置２１は、帯状部材Ｈの後端Ｈ２の貼り付けを行う貼付位置（第２貼付位置Ｐ２）まで貼付装置５０を移動させて、貼付装置５０を第２貼付位置Ｐ２に配置する。貼付装置５０の第２貼付位置Ｐ２への配置と同時に、駆動装置３がドラム２の回転を停止する。   The drum which rotates the drum 2 by the drive device 3 after the cutting device 4 cuts the belt-like member H, restarts the winding of the belt-like member H around the drum 2, and rotates the belt-like member H after cutting to the rear end H2. Wrap around 2 The belt-like member H is guided by the guide portion 12 and supplied to the drum 2. Further, in accordance with the winding of the band-shaped member H after cutting around the drum 2, the moving device 21 moves the sticking device 50 holding the rear end H2 of the band-shaped member H toward the rotating drum 2 (see FIG. 9). ). The rear end H <b> 2 of the band-shaped member H moves toward the drum 2 in accordance with the winding of the band-shaped member H by the sticking device 50. Subsequently, the moving device 21 moves the sticking device 50 to the sticking position (second sticking position P2) for sticking the rear end H2 of the belt-like member H, and places the sticking device 50 at the second sticking position P2. . Simultaneously with the placement of the sticking device 50 at the second sticking position P2, the driving device 3 stops the rotation of the drum 2.

移動装置２１により貼付装置５０を移動させて切断後の帯状部材Ｈを回転するドラム２に巻き付けるときに、制御装置７は、ドラム２の駆動装置３と移動装置２１を制御して、ドラム２の回転時間Ｔ１と貼付装置５０の移動時間Ｔ２とを一致させる。ドラム２の回転時間Ｔ１は、帯状部材Ｈの巻き付け完了までのドラム２の回転時間、つまり、ドラム２の回転開始から帯状部材Ｈの巻き付け完了によるドラム２の回転停止までの時間（ドラム２が回転する時間）である。貼付装置５０の移動時間Ｔ２は、貼付装置５０が第２貼付位置Ｐ２まで移動する移動時間、つまり、貼付装置５０の移動開始から第２貼付位置Ｐ２への配置による貼付装置５０の移動停止までの時間（貼付装置５０が移動する時間）である。制御装置７は、時間Ｔ１、Ｔ２の一方又は両方を調整する時間調整手段を有し、時間調整手段により２つの時間Ｔ１、Ｔ２を一致させる。これにより、制御装置７は、帯状部材Ｈの巻き付けが完了してドラム２の回転が停止したときに、貼付装置５０を第２貼付位置Ｐ２に配置する。   When the belt device H after being cut is wound around the rotating drum 2 by moving the sticking device 50 by the moving device 21, the control device 7 controls the driving device 3 and the moving device 21 of the drum 2 to control the drum 2. The rotation time T1 and the movement time T2 of the sticking device 50 are matched. The rotation time T1 of the drum 2 is the rotation time of the drum 2 until the winding of the belt-like member H is completed, that is, the time from the start of rotation of the drum 2 to the stop of the rotation of the drum 2 due to the completion of winding of the belt-like member Time). The movement time T2 of the sticking device 50 is the movement time for the sticking device 50 to move to the second sticking position P2, that is, from the start of movement of the sticking device 50 to the stop of movement of the sticking device 50 due to the placement at the second sticking position P2. This is the time (the time during which the sticking device 50 moves). The control device 7 has time adjusting means for adjusting one or both of the times T1 and T2, and the two times T1 and T2 are made to coincide with each other by the time adjusting means. Thereby, the control apparatus 7 arrange | positions the sticking apparatus 50 in the 2nd sticking position P2, when winding of the strip | belt-shaped member H is completed and rotation of the drum 2 stops.

具体的には、切断後の帯状部材Ｈの巻き付け開始時に、帯状部材Ｈの残余の長さとドラム２の残余の回転角度（長さと角度の制御情報という）に基づいて、制御装置７は、ドラム２の駆動装置３と移動装置２１を制御する。帯状部材Ｈの残余の長さは、ドラム２に巻き付けられていない部分の帯状部材Ｈの長さであり、ドラム２の残余の回転角度は、帯状部材Ｈの巻き付け完了までのドラム２の回転角度である。長さと角度の制御情報に基づいて、ドラム２の回転時間Ｔ１と貼付装置５０の移動時間Ｔ２とが一致するように、制御装置７は、ドラム２の周速度（帯状部材Ｈの巻き付け速度）と、移動装置２１による貼付装置５０の移動速度（後端Ｈ２の移動速度）を調整する。これにより、２つの時間Ｔ１、Ｔ２を一致させて、ドラム２が残余の回転角度だけ回転して停止するときに、貼付装置５０を第２貼付位置Ｐ２に配置する。   Specifically, at the start of winding of the strip-shaped member H after cutting, the control device 7 determines whether the drum 7 is a drum based on the remaining length of the strip-shaped member H and the remaining rotation angle of the drum 2 (referred to as length and angle control information). 2 driving device 3 and moving device 21 are controlled. The remaining length of the band-shaped member H is the length of the band-shaped member H that is not wound around the drum 2, and the remaining rotation angle of the drum 2 is the rotation angle of the drum 2 until the winding of the band-shaped member H is completed. It is. Based on the length and angle control information, the control device 7 determines the peripheral speed of the drum 2 (the winding speed of the belt-like member H) and the rotation time T1 of the drum 2 and the movement time T2 of the sticking device 50. The moving speed of the sticking device 50 by the moving device 21 (the moving speed of the rear end H2) is adjusted. As a result, the two times T1 and T2 are made to coincide, and when the drum 2 is rotated by the remaining rotation angle and stopped, the sticking device 50 is disposed at the second sticking position P2.

ここでは、ドラム２の周速度（図１１Ｃの速度Ｓ５）を変更せずに、貼付装置５０の移動速度（図１１Ｃの速度Ｓ６〜Ｓ７）を変更する。制御装置７は、ドラム２を予め設定された周速度で残余の回転角度だけ回転させたときのドラム２の回転時間Ｔ１を算出する。また、制御装置７は、帯状部材Ｈの残余の長さとドラム２の回転時間Ｔ１の算出値（Ｔ２）に基づいて、貼付装置５０の移動速度を算出する。制御装置７は、算出された貼付装置５０の移動速度で、移動装置２１により貼付装置５０を移動させる。   Here, the moving speed (speeds S6 to S7 in FIG. 11C) of the sticking device 50 is changed without changing the peripheral speed of the drum 2 (speed S5 in FIG. 11C). The control device 7 calculates the rotation time T1 of the drum 2 when the drum 2 is rotated by the remaining rotation angle at a preset peripheral speed. Further, the control device 7 calculates the moving speed of the sticking device 50 based on the remaining length of the belt-like member H and the calculated value (T2) of the rotation time T1 of the drum 2. The control device 7 moves the sticking device 50 by the moving device 21 at the calculated moving speed of the sticking device 50.

貼付装置５０は、移動装置２１により第２貼付位置Ｐ２に配置されて、帯状部材Ｈの後端Ｈ２をドラム２に押し付ける。これにより、貼付装置５０は、帯状部材Ｈの後端Ｈ２をドラム２に貼り付けて、後端Ｈ２を前端Ｈ１と重ねて配置する。このように、後端貼付手段である貼付装置５０により、切断後の帯状部材Ｈの後端Ｈ２を保持し、帯状部材Ｈの後端Ｈ２を、ドラム２における前端Ｈ１との接合位置に貼り付ける。接合位置は、後端Ｈ２が前端Ｈ１に接合されるドラム２上の所定位置であり、ドラム２に貼り付けられる前端Ｈ１の位置に対応して設定される。帯状部材Ｈの後端Ｈ２は、ドラム２に設定された接合位置に貼り付けられて、ドラム２に巻き付けられた帯状部材Ｈの前端Ｈ１に接合される。後端Ｈ２が前端Ｈ１との接合位置のドラム２に貼り付けられた後、固定装置３０は、押さえ部材３１をドラム２から取り外して、帯状部材Ｈの前端Ｈ１の固定を解除する。   The sticking device 50 is arranged at the second sticking position P <b> 2 by the moving device 21 and presses the rear end H <b> 2 of the belt-like member H against the drum 2. Thereby, the sticking device 50 sticks the rear end H2 of the belt-like member H to the drum 2, and arranges the rear end H2 so as to overlap the front end H1. Thus, the rear end H2 of the strip-shaped member H after cutting is held by the pasting device 50 as the rear end pasting means, and the rear end H2 of the strip-shaped member H is pasted to the joining position of the drum 2 with the front end H1. . The joining position is a predetermined position on the drum 2 where the rear end H2 is joined to the front end H1, and is set corresponding to the position of the front end H1 attached to the drum 2. The rear end H2 of the belt-like member H is attached to the joining position set on the drum 2 and joined to the front end H1 of the belt-like member H wound around the drum 2. After the rear end H2 is attached to the drum 2 at the joining position with the front end H1, the fixing device 30 removes the pressing member 31 from the drum 2 and releases the fixing of the front end H1 of the belt-like member H.

帯状部材Ｈの接合時には、移動装置２１により、移動ユニット８を移動させて、接合装置４０を前端Ｈ１と後端Ｈ２の加圧を行う位置（加圧位置Ｐ３）に配置する（図１０参照）。接合装置４０は、加圧部材４１により、接合位置の帯状部材Ｈの前端Ｈ１と後端Ｈ２を加圧して、帯状部材Ｈの前端Ｈ１と後端Ｈを接合する。その際、加圧部材４１により、前端Ｈ１と後端Ｈ２の重なる部分が加圧されて、前端Ｈ１と後端Ｈ２が重なる状態で接合される。前端Ｈ１と後端Ｈ２の接合により、帯状部材Ｈが環状に成形されて、環状部材Ｋの成形が完了する。その後（図３参照）、ガイド部１２の可動部１３を移動させて、供給装置１０のガイド部１２を縮める。また、貼付装置５０は、移動装置２１により待機位置に移動し、次の帯状部材Ｈの巻き付け開始まで待機する。   At the time of joining the belt-like member H, the moving unit 21 is moved by the moving device 21, and the joining device 40 is disposed at a position (pressing position P3) where the front end H1 and the rear end H2 are pressurized (see FIG. 10). . The joining device 40 pressurizes the front end H1 and the rear end H2 of the belt-like member H at the joining position by the pressurizing member 41 to join the front end H1 and the rear end H of the belt-like member H. At that time, the portion where the front end H1 and the rear end H2 overlap is pressurized by the pressure member 41, and the front end H1 and the rear end H2 are joined in a state of overlapping. By joining the front end H <b> 1 and the rear end H <b> 2, the band-shaped member H is formed in an annular shape, and the formation of the annular member K is completed. Thereafter (see FIG. 3), the movable portion 13 of the guide portion 12 is moved to contract the guide portion 12 of the supply device 10. The sticking device 50 is moved to the standby position by the moving device 21 and waits until the next belt member H starts to be wound.

以上説明したように、帯状部材Ｈの前端Ｈ１と後端Ｈ２を保持する貼付装置５０により、帯状部材Ｈの前端Ｈ１と後端Ｈ２をドラム２に正確に貼り付けることができる。また、帯状部材Ｈの後端Ｈ２を保持した状態で、前端Ｈ１がドラム２に貼り付けられた帯状部材Ｈを切断するため、帯状部材Ｈの変形と帯状部材Ｈの長さの変化を抑制して、帯状部材Ｈをドラム２に精度よく巻き付けることができる。帯状部材Ｈが、大きな残留応力を有する部材、又は、変形し易い部材であっても、帯状部材Ｈの変形と帯状部材Ｈの長さの変化を確実に抑制することができる。貼付装置５０により帯状部材Ｈの前端Ｈ１又は後端Ｈ２を常に保持しつつ、帯状部材Ｈをドラム２に正確に巻き付けることができる。   As described above, the front end H1 and the rear end H2 of the belt-like member H can be accurately stuck to the drum 2 by the sticking device 50 that holds the front end H1 and the rear end H2 of the belt-like member H. Further, in order to cut the belt-like member H with the front end H1 attached to the drum 2 while holding the rear end H2 of the belt-like member H, the deformation of the belt-like member H and the change in the length of the belt-like member H are suppressed. Thus, the belt-like member H can be wound around the drum 2 with high accuracy. Even if the belt-like member H is a member having a large residual stress or a member that is easily deformed, the deformation of the belt-like member H and the change in the length of the belt-like member H can be reliably suppressed. The band-shaped member H can be accurately wound around the drum 2 while the front end H1 or the rear end H2 of the band-shaped member H is always held by the sticking device 50.

ドラム２の回転時間Ｔ１と貼付装置５０の移動時間Ｔ２とを一致させることで、帯状部材Ｈの後端Ｈ２を前端Ｈ１との接合位置に正確に貼り付けることができる。また、帯状部材Ｈの長さにばらつきが生じたとしても、帯状部材Ｈを伸ばしながら、又は、帯状部材Ｈを縮めながら、帯状部材Ｈをドラム２に精度よく巻き付けることができる。帯状部材Ｈの前端Ｈ１と後端Ｈ２の接合量を調整することもできる。   By matching the rotation time T1 of the drum 2 and the movement time T2 of the sticking device 50, the rear end H2 of the belt-like member H can be accurately stuck to the joining position with the front end H1. Even if the length of the belt-like member H varies, the belt-like member H can be wound around the drum 2 with high accuracy while the belt-like member H is stretched or the belt-like member H is contracted. The joining amount of the front end H1 and the rear end H2 of the belt-like member H can also be adjusted.

従って、本実施形態の成形装置１と環状部材Ｋの成形方法によれば、ドラム２に巻き付けた帯状部材Ｈの前端Ｈ１と後端Ｈ２の接合の精度を向上させて、環状部材Ｋを精度よく成形することができる。帯状部材Ｈの接合量のばらつきが低減するため、作業者による接合の手直しをなくすこともできる。帯状部材Ｈの巻き付け途中に、切断装置４により帯状部材Ｈを巻き付け長さに切断することで、ドラム２と切断装置４の間の距離を短くすることができる。その結果、成形装置１をコンパクトにすることができる。固定装置３０により、帯状部材Ｈの前端Ｈ１をドラム２に固定するため、前端Ｈ１の不要な動きを防止して、前端Ｈ１をドラム２の所定位置に確実に保持することができる。   Therefore, according to the molding apparatus 1 and the molding method of the annular member K of the present embodiment, the accuracy of joining the front end H1 and the rear end H2 of the belt-like member H wound around the drum 2 is improved, and the annular member K is accurately formed. Can be molded. Since the variation in the joining amount of the belt-like member H is reduced, it is possible to eliminate reworking of joining by the operator. During the winding of the belt-shaped member H, the distance between the drum 2 and the cutting device 4 can be shortened by cutting the belt-shaped member H to the winding length by the cutting device 4. As a result, the molding apparatus 1 can be made compact. Since the front end H1 of the belt-like member H is fixed to the drum 2 by the fixing device 30, unnecessary movement of the front end H1 can be prevented and the front end H1 can be reliably held at a predetermined position of the drum 2.

なお、２つの貼付装置（前端貼付手段、後端貼付手段）により、それぞれ帯状部材Ｈの前端Ｈ１と後端Ｈ２を保持して貼り付けるようにしてもよい。ただし、１つの貼付装置５０により帯状部材Ｈの前端Ｈ１と後端Ｈ２の貼り付けを行うときには、成形装置１の構造を、より簡単にすることができる。また、帯状部材Ｈの前端Ｈ１のみをドラム２に貼り付けた状態（帯状部材Ｈのドラム２への巻き付けを開始する状態）で、貼付装置５０により帯状部材Ｈの後端Ｈ２を保持して、切断装置４により帯状部材Ｈを切断してもよい。この場合には、帯状部材Ｈの巻き付けを中断することなく、帯状部材Ｈをドラム２に連続して巻き付ける。貼付装置５０を配置する第１貼付位置Ｐ１と第２貼付位置Ｐ２は、同じ位置であってもよく、互いに異なる位置であってもよい。   Note that the front end H1 and the rear end H2 of the belt-like member H may be held and pasted by two pasting devices (front end pasting means and rear end pasting means), respectively. However, when the front end H1 and the rear end H2 of the belt-like member H are attached by one sticking device 50, the structure of the molding device 1 can be simplified. Further, in a state where only the front end H1 of the belt-like member H is stuck to the drum 2 (a state where winding of the belt-like member H around the drum 2 is started), the rear end H2 of the belt-like member H is held by the sticking device 50, The belt-like member H may be cut by the cutting device 4. In this case, the belt-like member H is continuously wound around the drum 2 without interrupting the winding of the belt-like member H. The first sticking position P1 and the second sticking position P2 at which the sticking device 50 is disposed may be the same position or different positions.

以上、帯状部材Ｈがタイヤ用のベルト部材である例を説明したが、帯状部材Ｈは、ベルト部材以外の帯状のタイヤ構成部材（トレッド、サイドゴム等）であってもよく、タイヤ構成部材以外の帯状部材であってもよい。また、帯状部材Ｈは、幅や断面形状を問わず、帯状をなす部材であればよい。帯状部材Ｈの前端Ｈ１と後端Ｈ２は、重ねずに、突き合わせた状態で接合してもよい。   The example in which the belt-shaped member H is a belt member for tires has been described above. However, the belt-shaped member H may be a belt-shaped tire constituent member (tread, side rubber, etc.) other than the belt member, and may be other than the tire constituent member. A strip-shaped member may be used. Moreover, the strip | belt-shaped member H should just be a member which makes strip | belt shape regardless of a width | variety or a cross-sectional shape. The front end H1 and the rear end H2 of the belt-like member H may be joined in a state of abutting without overlapping.
