Description

  The present invention relates to a strip printer and a strip printing method.

  In a web rotary printing machine (strip-shaped body printing machine) such as an offset rotary printing press, the air blowing amount of the turn bar changes due to a change in state such as the rotational speed of the printing press, and the bulge of the web applied to the turn bar changes. Therefore, the position of the web in the left-right direction (direction perpendicular to the conveyance direction) changes, and the position of the signature conveyed to the chopper folding part of the folding part provided on the downstream side of the turn bar also changes.

  Therefore, the web rotary printing press is provided with a turn bar position control device for adjusting the position of the web in the left-right direction. The turn bar position control device determines the position of the turn bar in the left-right direction according to the position (end position) of the end in the left-right direction of the web detected by the detector provided in the web conveyance path from the turn bar to the chopper folding part. Is automatically adjusted.

  By adjusting the position of the turn bar in the left-right direction with this turn bar position control device, the position of the signature conveyed to the chopper folding part of the folding part provided on the downstream side of the turn bar is adjusted, and the signature is the chopper folding part. It can be folded at the correct position.

  Also, in the folding part of the web rotary printing machine, the web is cut in the direction perpendicular to the transport direction at the center position of the blank part between the printed patterns to form a signature. Therefore, the cutting position with respect to the position of the printed pattern on the web may be shifted.

  Therefore, the web rotary printing machine is provided with a cutoff control device for adjusting the length of the web conveyance path. The cut-off control device detects the register mark printed on the web by a detector provided in the folding part, and the rotation phase of the printing press where the register mark is actually detected and the web is cut at the correct position. The position of the compensator roll provided on the upstream side of the detector is automatically adjusted according to the comparison result with the reference rotational phase of the printing press.

  By adjusting the position of the compensator roll with this cut-off control device, the length of the conveyance path of the web conveyed to the cutting cylinder of the folded portion is adjusted so that the web is cut at an accurate position in the cutting cylinder. ing.

  As a web rotary printing press provided with the above-mentioned turn bar position control device and cut-off control device, for example, techniques described in Patent Literature 1 and Patent Literature 2 can be cited.

  However, when the turn bar is moved in the left-right direction, not only the position of the web in the left-right direction is adjusted, but also the web transport path length changes, so the turn bar and the compensator roll are moved simultaneously. In some cases, excessive adjustment or hunting may occur.

  The present invention has been made in view of the above problems, and an object thereof is to prevent excessive adjustment and hunting in the position adjustment between the turn bar and the compensator roll.

  The control operation of the turn bar position control device 100 in the web rotary printing press 1 will be described with reference to FIGS. 3A to 3D, FIGS. 4A to 4C, and FIGS. 5A to 5D.

The count value of the rotational phase detection counter 212 of the printing press 1 is calculated and stored in the memory M206.

  Next, in step P19, the absolute value of the count value difference of the rotation phase detection counter 212 of the printing press 1 is calculated from the count value difference of the rotation phase detection counter 212 of the printing press 1 and stored in the memory M207. To read the allowable value (count value of the counter) from the memory M208, and in step P21, is the absolute value of the count value difference of the rotation phase detection counter 212 of the printing press 1 larger than the allowable value (count value of the counter)? Judge whether or not.

  If yes in step P21, the process proceeds to step P22. On the other hand, if the result is NO in Step P21, the process returns to Step P2 described above.

  Next, in step P22, the count value difference of the rotational phase detection counter 212 of the printing press 1—the correction count value conversion table of the compensator roll position detection counter 216 is read from the memory M209.

  Next, in step P23, the count value difference of the rotation phase detection counter 212 of the printing press 1 is read from the memory M206, and in step P24, the count value difference of the rotation phase detection counter 212 of the printing press 1 minus the compensator roll position detection. Using the correction count value conversion table of the counter 216, the correction count value of the compensator roll position detection counter 216 is obtained from the count value difference of the rotation phase detection counter 212 of the printing press 1 and stored in the memory M210.

  Next, the count value is read from the compensator roll position detection counter 216 in step P25 and stored in the memory M211, the correction count value of the compensator roll position detection counter 216 is read from the memory M210 in step P26, and the compensator roll in step P27. After the correction count value of the compensator roll position detection counter 216 is added to the count value of the position detection counter 216, and the count value of the target compensator roll position detection counter 216 is calculated and stored in the memory M212, Step P28 Thus, it is determined whether or not the target count value of the compensator roll position detection counter 216 is larger than the count value of the compensator roll position detection counter 216.

  If yes in step P28, a normal rotation command is output to the compensator roll position adjusting motor driver 214 in step P29, and then the process proceeds to step P30.

  Next, the count value of the target compensator roll position detection counter 216 is read from the memory M212 in step P30, and the count value is read from the compensator roll position detection counter 216 in step P31 and stored in the memory M211. In P32, it is determined whether or not the target count value of the compensator roll position detection counter 216 is the same as the count value of the compensator roll position detection counter 216.

  Next, if yes in step P32, output of the forward rotation command to the compensator roll position adjusting motor driver 214 is stopped in step P33, and then the process returns to step P2. On the other hand, if the result is NO in Step P32, the process returns to Step P30 described above.

  On the other hand, if NO in step P28, a reverse rotation command is output to the compensator roll position adjusting motor driver 214 in step P34, and then the process proceeds to step P35.

  Next, the count value of the target compensator roll position detection counter 216 is read from the memory M212 in step P35, and the count value is read from the compensator roll position detection counter 216 in step P36 and stored in the memory M211. In P37, it is determined whether or not the target count value of the compensator roll position detection counter 216 is the same as the count value of the compensator roll position detection counter 216.

  If yes in step P37, output of the reverse rotation command to the compensator roll position adjusting motor driver 214 is stopped in step P38, and then the process returns to step P2. On the other hand, if the result is NO in Step P37, the process returns to Step P35 described above.

  When the turn bar 70 is moved by the control operation of the cut-off control device 200 described above, that is, when a stand-by signal is output by the turn bar position control device 100, the cut-off control device 200 is set in a stand-by state, and the turn bar 70 When the flow of the web Wb is stabilized due to the movement, that is, when the standby release signal is output by the turn bar position control device 100, the cut-off control device 200 can be brought into the normal state.
