ヤストツパに関する。[Detailed Description of the Invention] [Industrial field of application] The present invention is to install the bead portion of the tire at a specified position of the first stage carcass when the 1st carcass produced by the molding machine is installed on the second stage drum. The present invention relates to a tire stopper used for

ム106からあるスキマｘを保って同心にリング110を支持
したものがあった。Conventionally, as shown in FIGS. 4 (a), (b), (c),
A slidable stopper plate 101 and its return spring 103,
A stopper composed of a stopper plate supporting plate 104, a supporting arm 107 and a supporting ring 105 is fixed to a drum 106, or a gap x formed from the drum 106 as shown in FIGS. 5 (a) and 5 (b). There was one who kept the ring 110 in concentric support.
第４図に示すようなものは、支持板104とストツパ板101
のすべりが常に円滑とは限らないため、ドラムの拡縮に
追従しないことがある。また構造が複雑、外径が大きく
なり作業の邪魔になるなどの問題点がある。As shown in FIG. 4, a support plate 104 and a stopper plate 101 are used.
Since the slip is not always smooth, it may not follow the expansion and contraction of the drum. Further, there are problems that the structure is complicated and the outer diameter becomes large, which hinders the work.
第５図に示すようなものは、基本的にドラム106とリン

５図（ｂ）に示す如く、タイヤの肩部120がこのスキｘ

ヤはｙだけ入り込んでしまう。タイヤの肩部の形状は一
定ではないのでｙの寸法は一定とならない等の問題点が
ある。The one shown in FIG. 5 basically has a gap x between the drum 106 and the ring 110, which allows expansion and contraction of the drum. Therefore, as shown in FIG. x
Since it enters the tire, the tire enters by y rather than the position z defined by the ring 110. Since the shape of the shoulder portion of the tire is not constant, there is a problem that the y dimension is not constant.
ストツパ板から支持腕までを一体化したバネ板を用いて
製作し、ドラム軸に嵌装した支持リングにストツパ板
（バネ板）の基部を固定し、ストツパ板の先端はドラム
軸に直交する方向に折曲げ、タイヤ肩部との当接面を形
成する。Manufactured using a spring plate that integrates the stopper plate and the support arm, the base of the stopper plate (spring plate) is fixed to the support ring that is fitted to the drum shaft, and the tip of the stopper plate is perpendicular to the drum shaft. Then, the contact surface with the shoulder portion of the tire is formed.
タイヤストツパがバネ板により作られているので、スト
ツパの先端はドラムの拡縮に追従して拡張できる。スト
ツパ先端は常にドラム外周に密着するので、タイヤの肩
部がストツパ先端とドラム外周の間に入り込むことがな
い。Since the tire stopper is made of a spring plate, the tip of the stopper can be expanded by following the expansion and contraction of the drum. Since the tip of the stopper is always in close contact with the outer circumference of the drum, the shoulder portion of the tire does not enter between the tip of the stopper and the outer circumference of the drum.
従って、タイヤストツパ先端の直径の変化は円滑に行な
われ、且つ、タイヤ肩部の正確な位置決めが可能にな
る。Therefore, the diameter of the tip of the tire stopper can be smoothly changed, and the tire shoulder can be accurately positioned.

のビード部を把持する。As shown in FIG. 2, the drum of the second stage molding machine for radial tires is divided into a drum right side 7 and a drum left side 9, which are installed on the drum shaft 6. And 9 have a structure that can be spread and contacted so that they have the same distance with respect to the center line A. In molding, the left and right bead portions of the 1st carcass 11 manufactured by the first-stage molding machine are installed on the left and right drums, respectively, and the drum grips the bead portions.
該装置はこのドラムのうち、駆動部８側のドラムに設置
されるもので、図示では右側ドラム７に取り付けられ
る。This device is installed in the drum on the drive unit 8 side of this drum, and is attached to the right drum 7 in the figure.
構造を第１図において説明する。ストツパ板１は図示の
如き形状を持つある幅を持つバネ板であり、この一端が

応じて適宜決定される。The structure will be described with reference to FIG. The stopper plate 1 is a spring plate having a certain width as shown in the figure, and one end of which is fixed to the support ring 4 by a bolt 3 so as to be sandwiched by a mounting block 2. The support ring 4 is fixed to the drum 7 with bolts 5. Although four stopper plates are shown in the figure, this is appropriately determined depending on the diameter of the drum and workability.
尚、実施例ではタイヤの当たる面をもバネ板の曲げ加工
で製作しているが、要求あればこの部分は別部品をバネ
板に取り付けた構造としても良い。In the embodiment, the contact surface of the tire is also manufactured by bending the spring plate, but if necessary, this part may have a structure in which a separate component is attached to the spring plate.
ドラム７のビード把持部は径が拡縮するので、ストツパ
板１はこれに追従することが要求される。第３図に示す

態となるが、このときストツパ板１は２点鎖線12に示す
よう変形してこれに追従できる。Since the diameter of the bead gripping portion of the drum 7 expands and contracts, the stopper plate 1 is required to follow this. As shown in FIG. 3, the drum 7 includes the bead portion 13 of the tire 11 and the stopper plate 1
After the contact with, the gripping portion expands into the state shown by the chain double-dashed line 10. At this time, the stopper plate 1 is deformed as shown by the chain double-dashed line 12 and can follow it.

滑に動作する。又これらに要求される給脂等の保守を全
く必要としない。(1) Since there is no sliding or swinging part due to a hinge or the like, there is no malfunction occurring in these parts and the operation is extremely smooth. Further, maintenance such as greasing required for these is not required at all.
（２）ドラム縮径時もドラム表面に接近したストツパ面
を持つので、位置が正確に規定できる。(2) Since the stopper surface is close to the drum surface even when the diameter of the drum is reduced, the position can be accurately specified.
（３）構造が簡単で安価である。(3) The structure is simple and inexpensive.
