Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application> The present invention relates to an external setup device that enables setup of a number cylinder, etc. of a number printing machine outside the printing machine.

<Prior Art> A number printing machine prints consecutive numbers and symbols on printed materials such as securities, various @ slips, and banknotes. FIG. 5 is a schematic structural diagram of the number printing machine. As shown in FIG. While 104 passes between the impression cylinder 106 and the number lpH05 equipped with a number cylinder attached to a character wheel (not shown), numbers and symbols are printed at predetermined locations, and the conveyor 108 sequentially sends 9 from the wave 107. It's about to be served.

FIG. 6 is an enlarged sectional view of the main parts of this number printing machine 101,
FIG. 7 is a plan view thereof. As shown in FIGS. 6 and 7, a mount ring 111 that is slidably attached to the number shaft 109 of the number barrel 105 via a key 110 is connected to the number shaft 109 through a port 113 by a mounting cap 112.
9 is fixed at any position in the longitudinal axis direction. A frame 117 with a number @116 is fixed to the outer circumferential surface of the mount ring 111 at any position on the outer circumferential surface of the mount ring 111 via a presser foot 115 by a presser bolt 114. A number changing cam shaft 119, which is arranged parallel to the numbering shaft 109 together with the impression cylinder 106 and the forming roller 118 of the inking unit 103 (see FIG. swing arm 121
The cam swing plate 12 is equipped with a conversion cam 122 that swings the
3 is numbered via a key 124 and is slidably fixed along the longitudinal axis direction of the camshaft 119. When the swing arm 121 of the number cylinder 116 attached to the mount ring 111 passes, this cam swing plate 123 is in the position shown by the solid line in FIG. 6, and swings the swing arm 121 by the conversion cam 122. Jirin 1zoe! ? ? It is designed to move forward by one pitch by making a missing J rotation. On the other hand, when an accident such as a paper feeding failure occurs, the number conversion camshaft 119 is rotated by a camshaft rocking means (not shown), and the cam rocking plate 123 is moved to the retracted position shown by the imaginary line in FIG. , the engagement with the swing arm 121 is released, and the intermittent rotation of the character wheel 120 is stopped.

Problems to be Solved by the Invention> In the above-described number printing, in order to adjust the printing position in the horizontal direction of the paper, the mount ring 111 is moved in the axial direction of the number axis 109, and the printing position is adjusted in the axial direction of the paper. In order to adjust the number cylinder 11B in the vertical direction, the number cylinder 11B is moved in the circumferential direction of the mount ring 111. Conventionally, these adjustments have been made while the number Wi4105 is attached to the number printing machine 101, which not only forces the worker into an unnatural working posture during II adjustment work, but also makes the number Since the operation of the printing press must be stopped, there is a problem in that the operating rate of the number printing press is reduced. Incidentally, in multi-page printing where multiple numbers are printed at the same time, it is necessary to adjust W4 for each of the multiple numbers 911B, but for example, in 50-sided number printing,
It took one to two days to adjust 0 number cylinders 116.

Further, during the above-mentioned adjustment, the number cylinder 116 is cleaned at the same time, and a large amount of cleaning liquid and lubricating oil are used at that time.

A portion of this cleaning liquid and lubricating oil remains on the number cylinder 116 even after adjustment, and if printing is continued in this state, the cleaning liquid and 1!4 lubricating oil will adhere to the printing paper, resulting in paper waste. Therefore, in the past, preparations before printing were carried out in which after adjustment, the paper was passed through the paper for about a thousand minutes, and the cleaning liquid and lubricating oil were scattered by centrifugal force and adhered to the paper, thereby removing them. This not only requires a large amount of paper, which is uneconomical, but also requires preparation before printing, which also causes a decline in the operating rate of the number printing machine.

Furthermore, in the above adjustment, when the mount ring 111 to which the number barrel 116 is attached is moved in the axial direction of the number shaft 109, the mounting position of the cam rocking plate 123 relative to the number conversion cam shaft 119 is also changed accordingly. Although it was necessary to make adjustments, this adjustment work was also time-consuming.

The present invention solves problems in setting up number cylinders, etc. of conventional number printing machines, and provides an external setup device that allows number cylinders, etc. to be set up outside the number printing machine, The purpose is to facilitate setup work and reduce the number of man-hours, as well as to improve the operating rate of the number printing machine.
