［従来の技術］ 一般に、板ガラスの洗浄は、多数枚を洗浄用治具に並
列保持して超音波洗浄槽に浸漬することにより行われて
いる。[Prior Art] In general, cleaning of glass sheets is performed by holding a large number of glass sheets in parallel in a cleaning jig and immersing them in an ultrasonic cleaning tank.
上記洗浄用治具は、第５図に示す様に、両端板１、２
間に２本の側面支持用治具３、４及び１本の下面支持用
治具５が取付けられ、各治具３、４、５には、その支持
面に等ピッチで歯部３′、４′、５′を形成しており、
各歯部によって板ガラスＡを直立状態で多数枚並列させ
て夫々３点支持するようにしている。As shown in FIG. 5, the cleaning jig includes two end plates 1 and 2.
Two side support jigs 3 and 4 and one lower surface support jig 5 are mounted between them, and the jigs 3, 4 and 5 have tooth portions 3 ′, 3. 4 ', 5'
A large number of glass sheets A are arranged in parallel in an upright state by each tooth portion, and each of them supports three points.
上記各治具３、４、５は同一構造からなるのでその一
つについて以下説明する。Since the jigs 3, 4, and 5 have the same structure, one of them will be described below.
従来の治具は、第６図に示すように、歯部３′を打ち
抜き等によって形成したフッ素樹脂等の耐食性樹脂より
なる板状のガラス支持体3aとステンレス等の耐食性剛体
よりなる基体3bから構成されており、ガラス支持体3a

た。As shown in FIG. 6, the conventional jig includes a plate-shaped glass support 3a made of a corrosion-resistant resin such as a fluororesin formed by punching a tooth 3 'and a base 3b made of a corrosion-resistant rigid body such as stainless steel. Is composed of a glass support 3a
Was fixed by caulking the base 3b.
［発明が解決しようとする問題点］ 前記従来の治具は、歯部３′の形成時の位置決め精度
を上げても洗浄工程にて反復使用する間に、ガラス支持
体3aが収縮し、各治具３、４、５間での歯部３′、
４′、５′の位置に経時的な変化、所謂ピッチずれを生
じ板ガラスＡの支持に支障をきたすという問題点があっ
た。[Problems to be Solved by the Invention] In the conventional jig, the glass support 3a shrinks while being repeatedly used in the cleaning process even if the positioning accuracy at the time of forming the tooth portions 3 'is increased. Tooth 3 ′ between jigs 3, 4, 5
There is a problem in that the positions 4 'and 5' change with time, that is, a so-called pitch shift, which hinders the support of the sheet glass A.
上記原因を検討した結果、従来の治具では、ガラス支
持体3aを基体3bにかしめ加工しており、このかしめ加工

かかり具合により各ガラス支持体で一定ではなく、その
ため、洗浄工程にて反復使用する間に自然に加熱冷却の
熱サイクルが繰り返され、ガラス支持体3aの圧縮応力が
解放された場合、各ガラス支持体の間で長手方向に伸縮
差が生じ、その結果、歯部３′、４′、５′のピッチず
れとなる。As a result of examining the above causes, in the conventional jig, the glass support 3a was caulked to the base 3b. During the caulking, the glass support 3a was compressed and deformed as shown in FIG.
As shown in the figure, it is stretched in the longitudinal direction and the width direction, and is fixed while compressive stress is applied. This compressive stress is not constant in each glass support due to the degree of the caulking force, and therefore, the thermal cycle of heating and cooling is spontaneously repeated during repeated use in the cleaning process, and the compressive stress of the glass support 3a is reduced. When released, a difference in expansion and contraction occurs between the glass supports in the longitudinal direction, resulting in a pitch shift of the teeth 3 ', 4', 5 '.
本発明は、従来における上記問題点に鑑みて提案され
たもので、その目的とするところは、歯部のピッチずれ
を著減させ得る板ガラスの洗浄用治具を提供しようとす
るものである。The present invention has been proposed in view of the above-described problems in the related art, and an object of the present invention is to provide a plate glass cleaning jig capable of significantly reducing a pitch shift of a tooth portion.
［問題を解決するための手段］ 本発明は、上記目的を達成するためになされたもの
で、板ガラスを並列保持する歯部が等ピッチで形成され

たことを特徴とする板ガラスの洗浄用治具である。Means for Solving the Problems The present invention has been made in order to achieve the above object, and has a plate-like glass support made of a corrosion-resistant resin in which teeth for holding sheet glass in parallel are formed at an equal pitch. A jig for cleaning a glass sheet, wherein the jig is fixed to a base made of a corrosion-resistant rigid body at one point and is allowed to expand by expansion.

止できる。[Operation] Fixing the glass support and the base at one point means that each glass support is not subjected to uneven compressive stress and is repeatedly subjected to a thermal action in the washing step. Since the expansion and elongation are fixed at a single point, they can escape therefrom, so-called expansion relief, so that the pitch shift of the teeth between the jigs can be prevented.

The fixing pins 3d are fixed to the base 3b by beating the fixing pins 3d into the fixing holes 3c of the glass support 3a and the base 3b. As the fixing pin 3d, a split pin or a spring pin 3d 'shown in FIG. 3 can be used if the base 3b is formed in a cylindrical shape. In particular, the fixing by the spring pin 3d' is performed only on the glass support 3a. What is necessary is to carve a slit 3e and drill a fixing hole 3c.
There is an advantage that it can be used repeatedly even when replacing the glass support 3a.
