Description

本開示は、加硫前のタイヤを成形するタイヤ成形装置に関する。   The present disclosure relates to a tire forming apparatus that forms a tire before vulcanization.

加硫前のタイヤの成形法として、例えば特許文献１に例示されるように、タイヤ構成体である第１ケース及び第２ケースをそれぞれ別々に複数の部材を組み付けて成形し、ドラムで保持した第１ケースに第２ケースをトランスファで移送して合体させる工程がある。   As a method for forming a tire before vulcanization, for example, as exemplified in Patent Document 1, a first case and a second case, which are tire constituents, are separately formed by assembling a plurality of members and held by a drum. There is a step of transferring the second case to the first case by transfer and combining them.

特開２００２−１１８０４号公報JP 2002-11804 A

トランスファは、モータ及びブレーキなどの駆動部によって直線レールに沿ってスライド移動し、第１ケースのタイヤ赤道と第２ケースのタイヤ赤道が一致する位置にトランスファが停止するように駆動部が制御する。   The transfer is slid along the straight rail by a drive unit such as a motor and a brake, and the drive unit controls the transfer so that the transfer stops at a position where the tire equator of the first case coincides with the tire equator of the second case.

しかし、装置を繰り返し使用していると、機械のがたや設備不良に起因して駆動部によるトランスファの停止位置が所望の位置から若干ずれてしまうことがある。この場合、第１ケースと第２ケースとがずれた状態で合体されてしまい、ユニフォミティが悪化してしまう場合がある。   However, when the apparatus is repeatedly used, the transfer stop position by the drive unit may slightly deviate from the desired position due to mechanical backlash or equipment failure. In this case, the first case and the second case are merged in a shifted state, and the uniformity may be deteriorated.

本開示は、このような課題に着目してなされたものであって、その目的は、トランスファの停止位置が所定の位置になることを保証するタイヤ成形装置を提供することである。   This indication is made paying attention to such a subject, and the object is to provide the tire forming device which guarantees that the stop position of a transfer turns into a predetermined position.

本開示は、上記目的を達成するために、次のような手段を講じている。   In order to achieve the above object, the present disclosure takes the following measures.

本開示のタイヤ成形装置は、
タイヤ構成体である第１ケースを外周面に保持するドラムと、
駆動部によってスライド移動可能に構成され、前記ドラムに保持される前記第１ケースの外周側にタイヤ構成体である第２ケースを移動させるトランスファと、を備え、
前記トランスファの可動部と固定部との間に設けられ、互いに嵌り合い且つ相対的に進退可能な凸部及び受け部を有し、前記凸部又は前記受け部の少なくとも一方は、進退方向に傾斜して前記凸部及び前記受け部を嵌り合う位置に案内する傾斜案内面を有し、嵌合動作によって前記トランスファの位置を所定位置に修正する位置決め機構が設けられている。 The tire molding apparatus according to the present disclosure includes:
A drum that holds the first case as a tire structure on the outer peripheral surface;
A transfer unit configured to be slidable by a drive unit and moving a second case, which is a tire component, to the outer peripheral side of the first case held by the drum;
Provided between the movable part and the fixed part of the transfer, and having a convex part and a receiving part that fit into each other and can move forward and backward relatively, at least one of the convex part or the receiving part is inclined in the forward and backward direction A positioning mechanism is provided that has an inclined guide surface that guides the convex portion and the receiving portion to a fitting position, and corrects the position of the transfer to a predetermined position by a fitting operation.

この構成によれば、駆動部によってトランスファが所定位置からずれた位置に停止したとしても、位置決め機構によって所定位置に修正されるので、トランスファが移動させる第２ケースと第１ケースの位置決め精度が向上し、ユニフォミティを向上させることが可能となる。   According to this configuration, even if the transfer is stopped at a position shifted from the predetermined position by the driving unit, the positioning mechanism corrects the transfer to the predetermined position, so that the positioning accuracy of the second case and the first case moved by the transfer is improved. In addition, the uniformity can be improved.

［成形装置］
図１及び図２に示すように、タイヤ成形装置は、ドラム１と、トランスファ２と、を有する。 [Molding equipment]
As shown in FIGS. 1 and 2, the tire molding apparatus includes a drum 1 and a transfer 2.

ドラム１は、複数部材を組み合わせて筒状に成形されたタイヤ構成体である第１ケースＣ１を保持する。ドラム１は周方向に分割された複数のドラム片で構成されており、各々のドラム片を縮径することで、第１ケースＣ１をドラム１から取り出すことが可能に構成されている。   The drum 1 holds a first case C1 that is a tire structure formed by combining a plurality of members into a cylindrical shape. The drum 1 is composed of a plurality of drum pieces divided in the circumferential direction, and the first case C1 can be taken out from the drum 1 by reducing the diameter of each drum piece.

トランスファ２は、環状フレーム２０と、環状フレーム２０の内周側に周方向に沿って複数設けられ、径方向に拡縮可能に構成されることで第２ケースＣ２を把持可能なセグメント２１と、を有する。環状フレーム２０は基台２２に取り付けられ、基台２２が２本のレール２３に載置されており、成形ドラム１の軸に平行にスライド移動可能に構成されている。２本のレール２３の間には、トランスファ２を移動させ停止させるための、モータやブレーキなどの駆動部（図示せず）が配置されている。トランスファ２は、ドラム１に保持される第１ケースＣ１の外周側に第２ケースＣ２を移動させる。   The transfer 2 includes an annular frame 20 and a plurality of segments 21 provided along the circumferential direction on the inner peripheral side of the annular frame 20 and configured to be able to expand and contract in the radial direction, thereby being capable of gripping the second case C2. Have. The annular frame 20 is attached to a base 22, the base 22 is mounted on two rails 23, and is configured to be slidable parallel to the axis of the forming drum 1. Between the two rails 23, a drive unit (not shown) such as a motor or a brake for moving and stopping the transfer 2 is disposed. The transfer 2 moves the second case C2 to the outer peripheral side of the first case C1 held by the drum 1.

トランスファ２の可動部と固定部との間には、凸部３０及び受け部３１を有する位置決め機構３が設けられている。凸部３０及び受け部３１は、互いに嵌り合う形状であり、相対的に進退可能に構成されている。   A positioning mechanism 3 having a convex portion 30 and a receiving portion 31 is provided between the movable portion and the fixed portion of the transfer 2. The convex portion 30 and the receiving portion 31 have a shape that fits each other, and are configured to be relatively advanced and retracted.

具体的に、本実施形態では、受け部３１は、トランスファ２の可動部である基台２２に設けられている。凸部３０は、トランスファ２の固定部であるレール２３に設けられている。凸部３０を受け部３１に向けて進退駆動させる進退駆動部３２（エアシリンダ）が設けられている。凸部３０及び進退駆動部３２はレール２３と高さ位置が重なるようにレール２３に取り付けてあるので、目立ちにくく、且つ省スペース化を図っている。   Specifically, in the present embodiment, the receiving portion 31 is provided on the base 22 that is a movable portion of the transfer 2. The convex portion 30 is provided on the rail 23 which is a fixed portion of the transfer 2. An advancing / retreating drive part 32 (air cylinder) for advancing and retracting the convex part 30 toward the receiving part 31 is provided. Since the convex portion 30 and the advancing / retreating drive portion 32 are attached to the rail 23 so that the height position thereof overlaps with the rail 23, it is difficult to stand out and saves space.

受け部３１は、スライド方向ＳＤに延びる長穴にボルトｖ１で締着されている。これにより、スライド方向ＳＤ以外の方向へは固定される。本実施形態では、基台２２を構成するブラケット２２ａの長穴に上下方向にボルトｖ１を挿通して締着している。さらに、受け部３１は、スライド方向ＳＤの両端３１ａ，３１ｂが、ボルトｖ２を介してスライド方向ＳＤに位置調整可能に挟持されている。本実施形態では、スライド方向ＳＤの一端３１ａはブラケット２２ａに接触しており、スライド方向ＳＤの他端３１ｂがボルトｖ２にて挟持されている。   The receiving part 31 is fastened with a bolt v1 in a long hole extending in the sliding direction SD. Thereby, it fixes in directions other than slide direction SD. In the present embodiment, the bolt v1 is inserted into the elongated hole of the bracket 22a constituting the base 22 in the vertical direction and fastened. Further, the receiving portion 31 is sandwiched so that both ends 31a and 31b in the sliding direction SD can be adjusted in position in the sliding direction SD via bolts v2. In the present embodiment, one end 31a in the sliding direction SD is in contact with the bracket 22a, and the other end 31b in the sliding direction SD is clamped by the bolt v2.

図２及び図３に示すように、凸部３０は、スライド方向ＳＤに直交する方向ＷＤに延びる台形柱状であり、スライド方向ＳＤの両側に、進退方向ＰＤに傾斜して凸部３０及び受け部３１を嵌り合う位置に案内する傾斜案内面３０ｓが形成されている。受け部３１は、上記台形柱状に対応する台形凹部を有し、台形凹部が傾斜案内面３１ｓを有する。凸部３０と受け部３１の接触面及び傾斜案内面３０ｓ，３１ｓは、スライド方向ＳＤに直交する方向ＷＤに延びている。好ましくは、凸部３０と受け部３１は、スライド方向ＳＤの寸法よりも直交方向ＷＤの寸法が長い方がよい。   As shown in FIGS. 2 and 3, the convex portion 30 has a trapezoidal column shape extending in the direction WD orthogonal to the sliding direction SD, and is inclined in the forward / backward direction PD on both sides of the sliding direction SD. An inclined guide surface 30s that guides 31 to the fitting position is formed. The receiving part 31 has a trapezoidal recess corresponding to the trapezoidal columnar shape, and the trapezoidal recess has an inclined guide surface 31s. The contact surfaces of the convex portion 30 and the receiving portion 31 and the inclined guide surfaces 30s, 31s extend in a direction WD orthogonal to the slide direction SD. Preferably, the convex part 30 and the receiving part 31 have a longer dimension in the orthogonal direction WD than the dimension in the sliding direction SD.

トランスファ２の移動が停止すると、図示しない制御部が進退駆動部３２（エアシリンダ）を作動させ、凸部３０が受け部３１に向けて移動し、嵌り合う。この嵌合動作のときに、傾斜案内面３０ｓ，３１ｓによって凸部３０と受け部３１との位置がずれていたとしても両者が嵌り合う位置に案内される。位置決め機構３は、この嵌合動作によってトランスファ２の位置を所定位置に修正することになる。   When the movement of the transfer 2 stops, a control unit (not shown) operates the advance / retreat drive unit 32 (air cylinder), and the convex portion 30 moves toward the receiving portion 31 and is fitted. During this fitting operation, even if the positions of the convex portion 30 and the receiving portion 31 are shifted by the inclined guide surfaces 30s, 31s, they are guided to a position where they are fitted. The positioning mechanism 3 corrects the position of the transfer 2 to a predetermined position by this fitting operation.

以上のように、本実施形態のタイヤ成形装置は、タイヤ構成体である第１ケースＣ１を外周面に保持するドラム１と、駆動部によってスライド移動可能に構成され、ドラム１に保持される第１ケースＣ１の外周側にタイヤ構成体である第２ケースＣ２を移動させるトランスファ２と、を備える。トランスファ２の可動部と固定部との間に設けられ、互いに嵌り合い且つ相対的に進退可能な凸部３０及び受け部３１を有し、凸部３０及び受け部３１の双方は、進退方向ＰＤに傾斜して凸部３０及び受け部３１を嵌り合う位置に案内する傾斜案内面３０ｓ，３１ｓを有し、嵌合動作によってトランスファ２の位置を所定位置に修正する位置決め機構３が設けられている。 As described above, the tire molding apparatus according to the present embodiment is configured to be slidable by the drum 1 that holds the first case C1 that is a tire component on the outer peripheral surface and the drive unit, and is held by the drum 1. The transfer 2 which moves the 2nd case C2 which is a tire structure on the outer peripheral side of 1 case C1 is provided. Provided between the movable portion and the fixed portion of the transfer 2, the projection 2 has a convex portion 30 and a receiving portion 31 that can be fitted to each other and relatively advance and retract, and both the convex portion 30 and the receiving portion 31 are in the advancing / retreating direction PD. There is provided a positioning mechanism 3 that has inclined guide surfaces 30s, 31s that are inclined to guide the protrusion 30 and the receiving portion 31 to a position where they fit together, and that corrects the position of the transfer 2 to a predetermined position by a fitting operation. .

この構成によれば、駆動部によってトランスファ２が所定位置からずれた位置に停止したとしても、位置決め機構３によって所定位置に修正されるので、トランスファ２が移動させる第２ケースＣ２と第１ケースＣ１の位置決め精度が向上し、ユニフォミティを向上させることが可能となる。   According to this configuration, even if the transfer unit 2 is stopped at a position deviated from the predetermined position by the drive unit, the second case C2 and the first case C1 to which the transfer 2 is moved are corrected by the positioning mechanism 3 to the predetermined position. Positioning accuracy can be improved, and uniformity can be improved.

本実施形態では、凸部３０と受け部３１の接触面及び傾斜案内面３０ｓ，３１ｓが、スライド方向ＳＤに直交する方向ＷＤに延びている。   In the present embodiment, the contact surfaces of the convex portion 30 and the receiving portion 31 and the inclined guide surfaces 30s, 31s extend in a direction WD orthogonal to the slide direction SD.

この構成によれば、スライド方向ＳＤの位置ズレだけでなく、スライド方向ＳＤと直交方向ＷＤとで定まる面における回転ズレも修正できる。さらに、凸部３０及び受け部３１が棒状ピンである場合に比べて強度を向上できる。   According to this configuration, not only the positional deviation in the sliding direction SD but also the rotational deviation in the plane determined by the sliding direction SD and the orthogonal direction WD can be corrected. Furthermore, the strength can be improved as compared with the case where the convex portion 30 and the receiving portion 31 are rod-shaped pins.

本実施形態では、受け部３１がトランスファ２の可動部に設けられ、凸部３０及び凸部３０を進退駆動させる進退駆動部３２がトランスファ２の固定部に設けられている。   In the present embodiment, the receiving portion 31 is provided in the movable portion of the transfer 2, and the convex portion 30 and the advance / retreat driving portion 32 that drives the convex portion 30 to advance and retract are provided in the fixed portion of the transfer 2.

凸部３０の進退駆動部３２を可動側に設ける場合に比べて、進退駆動部３２のスペースを確保しやすく、進退駆動部３２の配線などの取り回しがしやすく、装置を小型化可能となる。   Compared to the case where the advancing / retreating drive part 32 of the convex part 30 is provided on the movable side, it is easy to secure a space for the advancing / retreating drive part 32, the wiring of the advancement / retreating drive part 32 can be easily handled, and the apparatus can be downsized.

本実施形態では、受け部３１は、スライド方向ＳＤに延びる長穴にボルトｖ１で締着され、スライド方向ＳＤの両端３１ａ，３１ｂが、ボルトｖ２を介してスライド方向ＳＤに位置調節可能に挟持されている。   In the present embodiment, the receiving portion 31 is fastened with a bolt v1 to an elongated hole extending in the sliding direction SD, and both ends 31a and 31b of the sliding direction SD are clamped so as to be adjustable in the sliding direction SD via the bolt v2. ing.

この構成によれば、ボルトｖ２によって受け部３１のスライド方向ＳＤの位置を調整可能であるので、保守作業が容易となる。   According to this configuration, since the position of the receiving portion 31 in the sliding direction SD can be adjusted by the bolt v2, maintenance work is facilitated.

以上、本発明の実施形態について図面に基づいて説明したが、具体的な構成は、これらの実施形態に限定されるものでないと考えられるべきである。本発明の範囲は、上記した実施形態の説明だけではなく特許請求の範囲によって示され、さらに特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれる。   As mentioned above, although embodiment of this invention was described based on drawing, it should be thought that a specific structure is not limited to these embodiment. The scope of the present invention is shown not only by the above description of the embodiments but also by the scope of claims for patent, and further includes all modifications within the meaning and scope equivalent to the scope of claims for patent.

例えば、図４Ａに示すように、位置決め機構３は、トランスファ２のうちレール２３の外側となる部位に第１の位置決め機構３として配置されており、トランスファ２のうちレール２３を挟んで第１の位置決め機構３の対角となる部位に第２の位置決め機構３’が配置されていてもよい。図４Ａでは、第２の位置決め機構３’は、スライド方向ＳＤに直交する方向ＷＤに延びているが、スライド方向ＳＤと平行な方向に延びていてもよい。 For example, as shown in FIG. 4A, the positioning mechanism 3 is arranged as a first positioning mechanism 3 in a portion of the transfer 2 that is outside the rail 23, and the first positioning mechanism 3 is sandwiched between the rails 23 of the transfer 2. A second positioning mechanism 3 ′ may be disposed at a diagonal position of the positioning mechanism 3. In FIG. 4A, the second positioning mechanism 3 'extends in the direction WD orthogonal to the sliding direction SD, but may extend in a direction parallel to the sliding direction SD.

この構成によれば、横揺れ防止に加えて、傾き（捻れ）を防止することが可能となる。   According to this configuration, it is possible to prevent tilting (twisting) in addition to preventing rolling.

例えば、図４Ｂに示すように、第２の位置決め機構３’’を備え、第２の位置決め機構３’を構成する凸部３０と受け部３１の接触面及び傾斜案内面３０ｓ，３１ｓが、スライド方向ＳＤと平行な方向に延びていてもよい。   For example, as shown in FIG. 4B, the second positioning mechanism 3 ″ is provided, and the contact surface of the convex portion 30 and the receiving portion 31 and the inclined guide surfaces 30s, 31s constituting the second positioning mechanism 3 ′ are slid. It may extend in a direction parallel to the direction SD.

この構成によれば、スライド方向ＳＤの位置ズレだけでなく、スライド方向ＳＤと直交方向ＷＤとで定まる面における回転ズレも修正できる。   According to this configuration, not only the positional deviation in the sliding direction SD but also the rotational deviation in the plane determined by the sliding direction SD and the orthogonal direction WD can be corrected.

また、第２の位置決め機構３’を構成する凸部３０と受け部３１の接触面及び傾斜案内面３０ｓ，３１ｓが、スライド方向ＳＤに直交する方向に延びていてもよい。   Further, the contact surfaces of the convex portion 30 and the receiving portion 31 and the inclined guide surfaces 30s, 31s constituting the second positioning mechanism 3 'may extend in a direction perpendicular to the slide direction SD.

この構成によれば、２つの位置決め機構によって、スライド方向ＳＤの位置ズレだけでなく、スライド方向ＳＤと直交方向ＷＤとで定まる面における回転ズレも修正できる。   According to this configuration, not only the positional deviation in the sliding direction SD but also the rotational deviation in the plane determined by the sliding direction SD and the orthogonal direction WD can be corrected by the two positioning mechanisms.

また、図５Ｃに示すように、凸部３０は、台形ではなく、三角形状でもよい。   Moreover, as shown to FIG. 5C, the convex part 30 may not be trapezoid but triangular.

図２及び図５Ｃに示すように、受け部３１は、一つの部材でもよいが、図５Ａ及び図５Ｂに示すように、２つに分けて、独立して調整可能にした方がよい。一つの部材では凸部３０との接触によって磨耗した場合に、調節できないため、受け部３１全ての交換が必要であるが、受け部３１が２つの部材で構成されていれば、磨耗したとしても調節により継続利用できるからである。図５Ａ〜Ｃの中では、位置決め精度は図５Ｂが最もよい。   As shown in FIGS. 2 and 5C, the receiving portion 31 may be a single member. However, as shown in FIGS. 5A and 5B, it is preferable that the receiving portion 31 is divided into two parts and can be adjusted independently. When one member is worn due to contact with the convex portion 30, it cannot be adjusted, so it is necessary to replace the entire receiving portion 31. However, if the receiving portion 31 is composed of two members, This is because it can be used continuously by adjustment. 5A to 5C, the positioning accuracy is best in FIG. 5B.

また、本実施形態では、凸部３０及び受け部３１は、スライド方向ＳＤに直交する方向に所定長さを有するが、棒状（ピン状）に形成してもよい。   Moreover, in this embodiment, although the convex part 30 and the receiving part 31 have predetermined length in the direction orthogonal to the sliding direction SD, you may form in rod shape (pin shape).

上記の各実施形態で採用している構造を他の任意の実施形態に採用することは可能である。各部の具体的な構成は、上述した実施形態のみに限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々変形が可能である。 The structure employed in each of the above embodiments can be employed in any other embodiment. The specific configuration of each unit is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
