Abstract

PURPOSE:To provide the titled device capable of making adjustment of an image by a preset amount at a high accuracy by such an arrangement wherein a counter in which a required amount of image adjustment is preset is caused to start, and the number of pulses is counted down by the counter and its zero signal causes a solenoid and the OFF signal of a main machine to turn OFF. CONSTITUTION:A counter 34 in which an amount of adjustment whereby an image is to be moved is set by means of a set button 51 sends a set signal (a) to a control unit 38 which turns a start button 39 ON, and by this, an adjusting mechanism 12 begins to operate. Simultaneously when a solenoid 14 is turned ON, a start signal (d) is sent to the counter 34, and a driving gear 16 is pushed down and connected to a gear transmission mechanism 18. In synchronization with this, an oscillator 36 at the counter 34 sends a signal to a pulse motor driver 37, and a pulse motor 15 begins to rotate. At the same time, a reduction counter 35 begins to count down the number of pulse, and when it reaches zero, a zero signal (e) is sent to a control unit 38, which in turn causes the solenoid 14 and an OFF signal (c) of a main machine to turn OFF by an operation completion signal.

Description

[Detailed description of the invention] The present invention relates to an image adjustment cylinder for an A-no-seven printing press.

For each press plate including the paper plate of the Ef7 and G printing presses, place the image area 1+' at a predetermined position on the plate during plate making.71e
It is actually difficult to use L, so each l:t<'
The position of the image on the original and the plate was shifted by 1.

1 for the misalignment of this image area and the misalignment of the plate during printing, and for the plate cylinder during printing] 7 for the plate conversion - (-11
It is necessary to style the image f1 if1M and determine the position of the print image f, 't: relative to the paper feed.

・1 rubber cylinder, 3.2 com cylinders that also serve as impression cylinders, and 2.
Both sides provided on the plate cylinder are interlocked and connected,
Set each torso to b71-peripheral speed, and maintain a constant circumferential relationship (-), so the image position in the human 1111 force direction, that is, in the circumferential force direction, is 1111'll 'high8

To do this, remove the sharpness (・Match the 1-digit gear and the gear fixed to the impression cylinder to maintain the relationship in the circumferential direction. , - After disassociating the connection between the gear and the com cylinder, attach the shaft support I to the frame.
1 - Rotate the adjustment gear that meshes with the gear of the comb cylinder described in t), and rotate the compression via the gear in the comb cylinder ()), thereby rotating the control gear through the gear of the comb cylinder. and the circumferential direction of the impression cylinder (where l:5 is υ) are known.

According to the conventional device, after untying the joints of the gear box wrench etc. of the comb body, press L-] for manual operation. Rotate E torso, -17
Since it changes the circumferential relationship with the rubber cylinder, the circumferential adjustment is based on intuition. Therefore, the operator is required to be highly skilled and highly skilled. 1..1.II 5 It takes a long time to get things done (1.
In addition, the 41AI screw 1 is not properly adjusted, so when fitting it, it is easy to create a gap, and the accuracy is poor.

~・5, 6 & 7, 8, 9 are aligned with the phase 11 at 11°11 and are meshed with a drive gear (not shown), so that each cylinder maintains a constant circumferential relationship at the same circumferential speed -C 3. Here, the inner cylinder key 5.7 has a light 18;
7 is adapted to be rotated by separately provided adjustment mechanisms 10 and II, which will be described later.

However, l? When the body gear 5 rotates due to the straightening mechanism 10, the body gear 6 is in mesh with this relationship.
Since the 1st printing cylinder 2 is rotated, the positional relationship in the circumferential direction (11) opposite to the 3rd and 1st printing cylinders Ib is changed, and the 1st printing cylinder 2 is
The 1'i-position is adjusted to 1ill'll.
