Description

本発明は、タイヤの不均一性を計測するタイヤユニフォーミティマシン等のタイヤ試験機におけるリム交換装置及びリム交換方法に関する。   The present invention relates to a rim replacement apparatus and a rim replacement method in a tire testing machine such as a tire uniformity machine that measures tire non-uniformity.
この種のタイヤ試験機において、上,下擬似リムと被試験タイヤとを嵌合する方法については、大別して二通りの方法がある。   In this type of tire testing machine, there are roughly two methods for fitting the upper and lower pseudo rims with the tire under test.
その一つは、特許文献1に開示されているように、被試験タイヤを搬入・搬出するローラコンベアで構成されたタイヤ搬送手段の上方に固定される上部スピンドルと、タイヤ搬送手段の下方位置(リム移動手段がタイヤ搬送手段の下方に設置されている場合は、リム移動手段の下方位置)である下降位置と上部スピンドルとの連結位置である上昇位置との間を昇降する下部スピンドルと、下部スピンドルを昇降駆動する昇降手段と、で構成されたものがある。   One of them is, as disclosed in Patent Document 1, an upper spindle fixed above a tire conveying means constituted by a roller conveyor for carrying in and out a tire under test, and a lower position of the tire conveying means ( When the rim moving means is installed below the tire conveying means, a lower spindle that moves up and down between a lowered position that is a lower position of the rim moving means) and an elevated position that is a connecting position of the upper spindle; And a lifting means for driving the spindle up and down.
そして、このタイヤ試験機におけるリム交換は次の手順で自動的に行われる。
(a)先ず、タイヤ搬送手段の下方に設置されているリム移動手段のリムパレットに、上,下リムを一体として(積み重ねて)載荷して事前準備する。尚、リムパレットは保持孔を有しており、そこに下リムがセンタリングされて保持される構造になっている。
(b)次に、リムパレットをスピンドルの軸芯位置へ移動させた後、リム移動手段の下方で待機していた昇降手段を上方駆動して、上,下リムを一体として上昇させ、上リムを上部スピンドルに、下リムを下部スピンドルにそれぞれ連結・固定する。
(c)最後に、下リムが連結・固定された下スピンドルをタイヤ搬送手段の下方迄下降させると共に、リムパレットをリム移動手段によりスピンドルの軸芯位置より外方へ移動させる。
以上で、リム交換時の上,下リムの取付けが終了する。尚、上,下リムの取外しは逆の動作であるので説明は省略する。
The rim replacement in the tire testing machine is automatically performed according to the following procedure.
(A) First, the upper and lower rims are loaded together (stacked) on the rim pallet of the rim moving means installed below the tire conveying means and prepared in advance. The rim pallet has a holding hole, and the lower rim is centered and held there.
(B) Next, after moving the rim pallet to the axis position of the spindle, the elevating means waiting under the rim moving means is driven upward to raise the upper and lower rims together, and the upper rim Are connected and fixed to the upper spindle and the lower rim to the lower spindle.
(C) Finally, the lower spindle, to which the lower rim is connected and fixed, is lowered to below the tire conveying means, and the rim pallet is moved outward from the spindle center position by the rim moving means.
This completes the installation of the upper and lower rims when the rim is replaced. Since the removal of the upper and lower rims is the reverse operation, the description is omitted.
もう一つは、特許文献2及び特許文献3に開示されているように、タイヤ搬送ライン(搬送ローラ)の下方に設置されたスピンドルと、被試験タイヤをスピンドルに固定された下リムに装着するために、搬送手段位置からスピンドルを貫通して下降するローラフレームと、上リムを把持するチャックと、チャックを昇降する昇降ハウジングと、で構成されたものがある。   The other is, as disclosed in Patent Document 2 and Patent Document 3, a spindle installed below a tire transport line (transport roller) and a test tire are mounted on a lower rim fixed to the spindle. For this purpose, there is a roller frame that descends through the spindle from the conveying means position, a chuck that grips the upper rim, and a lifting housing that lifts and lowers the chuck.
そして、このタイヤ試験機における計測は次の手順で行われる。
(a)先ず、被試験タイヤを搬送ローラにてスピンドルの軸芯位置まで搬入する。この時、被試験タイヤはローラフレーム上に位置する。
(b)次に、ローラフレームを下降し、被試験タイヤを下リムに着座させる。
(c)最後に、昇降ハウジングを下降して被試験タイヤを挾持し、上リムをロックシャフトを介してスピンドルに固定する。
以上で、被試験タイヤは上,下リムに保持され、スピンドルを回転させることで所要の計測が可能となる。
And the measurement in this tire testing machine is performed in the following procedure.
(A) First, the tire to be tested is carried to the spindle center position by the conveyance roller. At this time, the tire under test is positioned on the roller frame.
(B) Next, the roller frame is lowered and the test tire is seated on the lower rim.
(C) Finally, the elevating housing is lowered to hold the tire under test, and the upper rim is fixed to the spindle via the lock shaft.
Thus, the tire under test is held on the upper and lower rims, and the required measurement can be performed by rotating the spindle.
一方、リム交換は次の手順で行われる。
(a)先ず、上,下リムを一体で(積み重ねて)前述したパレットのような座板(保持孔の必要はない)に載荷して事前準備する。尚、上,下リム組を同時に吊り上げ可能なように、上,下リムの外周部同士を周方向に2分割された断面略チャンネル型のアタッチメントで保持する必要がある。
(b)次に、座板に積載された上,下リム組をスピンドルの軸芯位置まで移動させた後、昇降ハウジングを下降させて上リムをチャックし、その後上,下リム組を若干上昇させて座板を除く。
(c)最後に、昇降ハウジングを下降させて下リムをスピンドルに着座させ、アタッチメントを取り外す。
以上で、リム交換時の上,下リムの取付けが終了する。尚、上,下リムの取外しは逆の動作であるので説明は省略する。
On the other hand, rim replacement is performed according to the following procedure.
(A) First, the upper and lower rims are integrated (stacked) and loaded in advance on a seat plate (no need for a holding hole) such as the pallet described above. In addition, it is necessary to hold the outer peripheral portions of the upper and lower rims with a substantially channel-shaped attachment that is divided into two in the circumferential direction so that the upper and lower rim groups can be lifted simultaneously.
(B) Next, after moving the upper and lower rim assemblies loaded on the seat plate to the spindle axis position, the elevator housing is lowered to chuck the upper rim, and then the upper and lower rim assemblies are slightly raised. Let the seat plate be removed.
(C) Finally, the elevating housing is lowered, the lower rim is seated on the spindle, and the attachment is removed.
This completes the installation of the upper and lower rims when the rim is replaced. Since the removal of the upper and lower rims is the reverse operation, the description is omitted.

このように構成されるため、次に、被試験タイヤTのサイズが変わり、それに対応して上,下擬似リム26A,26Bを交換する時の動作を図6A,図6Bを用いて説明する。尚、本動作説明は新しい交換用の上,下擬似リム26A,26Bを、既に古い交換用の上,下擬似リム26A,26Bが取り外された上リムエレベータ30と下部スピンドル22Bに取り付ける際の説明であり、古い交換用の上,下擬似リム26A,26Bを取り外す動作は後述する新しい交換用の上,下擬似リム26A,26Bを取り付ける動作の逆の動作であることが自明であるので、説明は省略する。   Since it is configured as described above, the operation when the size of the tire T to be tested is changed and the upper and lower pseudo rims 26A and 26B are replaced correspondingly will be described with reference to FIGS. 6A and 6B. In this operation, the new replacement upper and lower pseudo rims 26A and 26B are attached to the upper rim elevator 30 and the lower spindle 22B from which the old replacement upper and lower pseudo rims 26A and 26B have been removed. It is obvious that the operation for removing the old replacement upper and lower pseudo rims 26A and 26B is the reverse of the operation for attaching the new replacement upper and lower pseudo rims 26A and 26B, which will be described later. Is omitted.
先ず、リムストッカー50上で任意のストッカーフレーム55A(〜55C)に所定サイズの上,下擬似リム26A,26Bを装着して準備する(図6Aの(1)参照)。   First, on the rim stocker 50, an arbitrary stocker frame 55A (˜55C) is prepared by mounting lower pseudo rims 26A and 26B having a predetermined size (see (1) in FIG. 6A).
次に、リムエレベータ30とベルトコンベヤ27(27a,27b)を所定の位置で待機させる。即ち、リムエレベータ30のチャック爪35を開放すると共に、ベルトコンベヤ27(27a,27b)を下降限まで下降させ、かつ一対のベルト27a,27bの間隔を狭めておくのである(図6Aの(2)参照)。   Next, the rim elevator 30 and the belt conveyor 27 (27a, 27b) are put on standby at predetermined positions. That is, the chuck pawl 35 of the rim elevator 30 is opened, the belt conveyor 27 (27a, 27b) is lowered to the lower limit, and the distance between the pair of belts 27a, 27b is reduced ((2 in FIG. 6A). )reference).
次に、任意のストッカーフレーム55A(〜55C)を旋回させた後、リムストッカー50を前進限の位置まで前進させて任意のストッカーフレーム55A(〜55C)の上部スピンドル22Aの軸芯を下部スピンドル22Bの軸芯と一致させる(図6Aの(2)参照)。   Next, after rotating an arbitrary stocker frame 55A (˜55C), the rim stocker 50 is advanced to a forward limit position, and the axis of the upper spindle 22A of the optional stocker frame 55A (˜55C) is moved to the lower spindle 22B. (Refer to (2) in FIG. 6A).
次に、リムエレベータ30を下降させてチャック爪35で上部スピンドル22Aをチャックした後、再びリムエレベータ30を上昇させて上擬似リム26Aを所定の位置まで吊り上げると共に、ベルトコンベヤ27(27a,27b)を上昇させて下擬似リム26Bを持ち上げ、任意のストッカーフレーム55A(〜55C)のU字板61より浮かす(図6Aの(2)参照)。   Next, after the rim elevator 30 is lowered and the upper spindle 22A is chucked by the chuck claws 35, the rim elevator 30 is raised again to lift the upper pseudo rim 26A to a predetermined position, and the belt conveyor 27 (27a, 27b). Is raised to lift the lower pseudo rim 26B and float above the U-shaped plate 61 of any stocker frame 55A (˜55C) (see (2) in FIG. 6A).
次に、リムストッカー50を後進限の位置まで後進させて待機させる(図6Bの(5)参照)。   Next, the rim stocker 50 is moved backward to the position of the rearward limit and waited (see (5) in FIG. 6B).
次に、リムエレベータ30を上昇させて上擬似リム26Aを被試験タイヤTの受け入れ位置まで上昇させると共に、ベルトコンベヤ27(27a,27b)を下降させて下擬似リム26Bを下部スピンドル22Bに装着し、次いで、一対のベルト27a,27bの間隔を拡げてベルトコンベヤ27(27a,27b)をタイヤ搬送ラインの上昇限の位置まで上昇させて被試験タイヤTを搬入する(図6Bの(6)参照)。   Next, the rim elevator 30 is raised to raise the upper pseudo rim 26A to the receiving position of the tire T to be tested, and the belt conveyor 27 (27a, 27b) is lowered to attach the lower pseudo rim 26B to the lower spindle 22B. Next, the distance between the pair of belts 27a and 27b is widened to raise the belt conveyor 27 (27a and 27b) to the position of the ascending limit of the tire conveyance line, and the tire T to be tested is carried in (see (6) in FIG. 6B). ).
最後に、ベルトコンベヤ27(27a,27b)を下降させて被試験タイヤTを計測位置で下擬似リム26Bに保持させた後、リムエレベータ30を下降させて上部スピンドル22Aを下部スピンドル22Bへ挿入・連結すると共に上擬似リムで被試験タイヤTを保持して被試験タイヤTをチャックする(図6Bの(7)参照)。   Finally, the belt conveyor 27 (27a, 27b) is lowered to hold the test tire T on the lower pseudo rim 26B at the measurement position, and then the rim elevator 30 is lowered to insert the upper spindle 22A into the lower spindle 22B. At the same time, the tire T to be tested is held by the upper pseudo rim to chuck the tire T to be tested (see (7) in FIG. 6B).
以上でリム交換動作は終了し、この後、上,下擬似リム26A,26B間にエアを吹き付けて被試験タイヤTをインフレートしてから、上,下部スピンドル22A,22Bを回転させることで、タイヤユニフォーミティマシンにおける所要の計測処理が可能となる。   The rim exchanging operation is completed as described above. After that, air is blown between the upper and lower pseudo rims 26A and 26B to inflate the test tire T, and then the upper and lower spindles 22A and 22B are rotated. The required measurement processing in the tire uniformity machine is possible.
このようにして本実施例によれば、下疑似リム26Bをリムストッカー50における座板58A,58Bの下面側にU字板61を介して吊り下げる形態で搬送することにより、上,下疑似リム26A,26Bを一体として搬送する方式で必要なリムパレットやアタッチメントが不要となる。   Thus, according to the present embodiment, the upper and lower pseudo rims 26B are transported in a form suspended from the lower surfaces of the seat plates 58A and 58B of the rim stocker 50 via the U-shaped plate 61. Rim pallets and attachments that are necessary for the method of transporting 26A and 26B as a unit are not required.
また、既存の昇降可能でかつ一対のベルト27a,27bの間隔調整が可能なベルトコンベヤ27をリム交換時の下疑似リム26Bの交換に利用するので、下疑似リム26をリム下方より支持昇降する専用設備を追設する必要はなくなる。   Further, since the existing belt conveyor 27 that can be raised and lowered and the distance between the pair of belts 27a and 27b can be adjusted is used for replacing the lower pseudo rim 26B at the time of rim replacement, the lower pseudo rim 26 is supported and raised from below the rim. There is no need to install dedicated equipment.
これらの結果、容易でかつ安価にリム交換の自動化が図れる。   As a result, rim replacement can be automated easily and inexpensively.
