本考案は回転軸に嵌装した送りロール、工具等のヘッド
を前記回転軸の軸線方向の任意の位置に迅速に移動して
固定できるようにしたヘッド固定装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a head fixing device capable of quickly moving and fixing the head of a feed roll, tool, etc. fitted onto a rotating shaft to any position in the axial direction of the rotating shaft.
従来例を段ボール箱の印刷機について述べると、この印
刷機の送りロールは、ロフト替え時、シート状に展開さ

作業が各送りロールのヘッドについて行われ、これらに
要する時間がかなりかかる欠点があった。As an example of a conventional printing machine for corrugated boxes, when changing the loft, the feed roll of this printing machine changes its position on the rotation axis due to the difference in the dimensions of the corrugated boxes that are unfolded into sheets. It is necessary to change it each time, and therefore, as shown in Figs. 1 and 2, the feed roll 1
The head bolt 4 is made by tightening the heads 2 and 3 which are divided into two parts.
and 4, respectively, and then retightening the head bolts 4 and 4, respectively, for each feed roll head, which has the disadvantage that it takes a considerable amount of time. Ta.
本考案は上記問題点を改善するもので、以下、本考案の
実施例を、印刷機の送りロールのヘッド固定装置につい
て、図面により例示説明する。The present invention is intended to improve the above-mentioned problems, and hereinafter, an embodiment of the present invention will be illustrated and explained with reference to the drawings regarding a head fixing device for a feed roll of a printing press.
回転軸１０の軸表面には、軸線方向にラック２０がねじ
１１により固着されている。A rack 20 is fixed to the shaft surface of the rotating shaft 10 in the axial direction with screws 11.
送りロール３０のヘッドは、ヘッド片３１及び３２に２
分割され、両ヘッド片は、ヘッドボルト４１及び４２に
より緊結されて一体化し、回転軸１０に摺動自在に嵌合
している。The head of the feed roll 30 has two head pieces 31 and 32.
The head pieces are divided into two parts, which are integrally connected by head bolts 41 and 42, and are slidably fitted onto the rotating shaft 10.
ヘッド片３１には、ラック２０を通過させる下切り欠き
３１１が設けられると共に下切り欠き３１１に連通ずる
上切り欠き３１２が設けられ、この切り欠き内には、ス
トッパー５０がヘッド孔３１３から挿入したピン６１に
より回動自在に支持されて収容されている。The head piece 31 is provided with a lower notch 311 through which the rack 20 passes, and an upper notch 312 that communicates with the lower notch 311, into which the stopper 50 is inserted through the head hole 313. It is rotatably supported and accommodated by a pin 61.
ストッパー５０は先端にラック２０と噛合する歯片５１
が取りつけられると共に後端５２近くに凹所５３を形成
して、ヘッド片３１に設けた凹所３１４との間に圧縮コ
イルバネ６２を介在させている。The stopper 50 has a tooth piece 51 at its tip that engages with the rack 20.
A recess 53 is formed near the rear end 52, and a compression coil spring 62 is interposed between the recess 53 and the recess 314 provided in the head piece 31.
従って、ストッパー５０は、その先端の歯片５１がバネ
６２の弾性力で押し下げられて、ラック２０に噛着して
いるので、送りロール３０のヘッドは回転軸１０に固定
されており、ストッパー５０の後端５２をバネ６２の弾
性力に坑して押し下げると、歯片５１がラック２０から
離脱して、送りロール３０のヘッドは、回転軸１０のラ
ック２０上を容易に移動でき、ストッパー５０の後端５
２の押し下げをやめると、直ちにその位置でストッパー
５０の歯片５１がラック２０に噛着して送りロール３０
のヘッドを回転軸１ｕに固定できる。Therefore, the tooth piece 51 at the tip of the stopper 50 is pushed down by the elastic force of the spring 62 and bites into the rack 20, so the head of the feed roll 30 is fixed to the rotating shaft 10, and the stopper 50 When the rear end 52 is pressed down against the elastic force of the spring 62, the toothed piece 51 separates from the rack 20, and the head of the feed roll 30 can easily move on the rack 20 of the rotating shaft 10, and the stopper 50 rear end 5
2, the tooth piece 51 of the stopper 50 immediately bites the rack 20 at that position, and the feed roll 30
head can be fixed to the rotating shaft 1u.
以上のように、本考案によれば、送りロール等のヘッド
を回転軸の軸線方向の任意の位置に迅速に移動させて直
ちに固定できる。As described above, according to the present invention, the head of the feed roll or the like can be quickly moved to any position in the axial direction of the rotating shaft and immediately fixed.
