Description
(1) lWeb=vWeb*tWeb
但しtWeb:送りベルトTBの周回所要時間
vWeb:送りベルトTBの平均速度(処理速度)
lWeb:送りベルトTBの長さ
により表される関係が成り立つ。
(2) TLE(j)=TSeam(u)+j*(tWeb/k)
但しk:送りベルトTB上にあるフレームの個数
u:送りベルトTBのこれまでの周回回数
に示す時差関係が成り立つ(j:フレーム番号)。
(3) TLE(n,0)=TLE(j)
TLE(n,1)=TLE(j+ro)
によって表される関係が成り立つように、シート送り動作を制御しまたシート先端位置を定める。この式中、TLE(n,s)は第nシートの表側(s=0)及び裏側(s=1)が先端センサLESを通過するタイミングであり、roは表面印刷に使用したフレームの番号と裏面印刷に使用するフレームの番号の差即ちフレーム番号差である。このフレーム番号差roは移送路の長さとその移送路上でのシート送り速度の比で決まる定数値であり、これには送りベルトTBだけでなく反転ループDLも移送路として関わってくる。反転ループDLとは、1個又は複数個の印刷ユニットDWを通り抜けたシートのうちその裏側への印刷が必要なものをシート反転ユニットINで表裏反転させて回送し、それ以外のものを排出トレイEXに排出する移送路セグメントである。
(4) tFehl=TLEXX−TXX
但しXX:ユニット名称
を用いた単純な差の計算で求めることができる。
Claims (1)
- 印刷機内の移送路上を回転するとともに、複数のフレームに区画された連続回転型の送りベルトにシートを搬送させる、ディジタル印刷機内シート制御方法であって、
上記送りベルトが回転する移動経路上には、上記送りベルトに設けられた原点を検知する原点検知センサと、印刷ユニットと、上記印刷ユニットの上流に設けられた給紙ユニットと、上記給紙ユニットの上流に設けられたシート反転ユニットと、上記給紙ユニットと上記シート反転ユニットの間に設けられたシート速度調整ユニットと、が設けられ、
上記原点検知センサが上記送りベルトの原点を検知した検知時点と、上記検知時点から計数されるパルス信号とに基づいて、それぞれの上記フレームの位置を求め、
