とを備えている。 A continuous water supply device is known as a type of water supply device that supplies dampening water to a plate on a plate cylinder in a rotary printing press. This type of water supply device generally consists of a water bucket that stores dampening water, a water fountain roller that rotates inside the fountain to pull up the dampening water, and a water fountain roller that is located between the fountain roller and the plate cylinder. It consists of a roller device that sequentially transfers the lifted dampening water and supplies it to the plates on the plate cylinder. Among these, the forming roller device consists of a forming roller formed to be detachably attached to the plate cylinder, a metering roller disposed between the forming roller and the water base roller with their peripheral surfaces facing each other, and a transfer roller. and a group of rollers such as rollers.
このような給水着ローラ装置においては、版の
耐刷力を維持し、版の取付け部で発生する振動を
抑えて品質の低下を防止する上において、版胴に
対する着ローラの接触圧がきわめて重要な要素を
占めている。 In such a water feed roller device, the contact pressure of the roller against the plate cylinder is extremely important in order to maintain the printing durability of the plate, suppress vibrations generated at the plate mounting area, and prevent quality deterioration. occupies a large number of elements.

せることによつて行なわれる。 On the other hand, in a rotary printing press, the plate is formed into a certain shape by an external plate bending machine and then attached to the plate cylinder, but this plate bending process may cause the plate to be misaligned, or the plate may be If the product is crooked during the installation process, and as a result exceeds the allowable registration error, this must be corrected by some method. Conventionally, therefore, if the entire printing plate is misaligned in the circumferential or axial direction of the printing cylinder, this is corrected during machine operation using a known correction device. In addition, if the left and right sides of the plate are twisted and attached to the plate cylinder, removing the plate and bending it again causes problems such as time loss and reduced strength of the plate, and it is difficult to guarantee accuracy after reinstallation. Since this is not possible, so-called plate cylinder twist adjustment is carried out, which involves twisting the plate cylinder with respect to the blanket cylinder while the plate is attached to the plate cylinder, and slightly shifting the axes of both cylinders. This twist adjustment involves rotating one side of the plate cylinder bearing, which is eccentric to the outer circumferential surface supported by the frame and the inner circumferential surface supporting the plate cylinder, to slightly shift the phase relative to the other bearing. This is done by shifting the

いた。 Conventionally, the procedure for adjusting the contact pressure of the forming roller against the plate cylinder and adjusting the twist of the plate cylinder as explained above is to first adjust the contact pressure of the forming roller before printing, then make a test print and check the plate. In many cases, a method is used in which the twist is adjusted when there is a twist. In this way, if the twist adjustment is performed later, the axis of the plate cylinder will move, and the contact pressure of the forming roller that has been painstakingly adjusted will change, and the contact pressure will have to be adjusted again. Adjustment is troublesome and takes a long time, and the non-operating time of the machine is extended, which greatly reduces productivity.

In conventional devices, these are performed by separate mechanisms, resulting in a complex structure and an inability to simplify operations.

, the shaft center F of the fitting outer circumferential surface 32a and the inner circumferential shaft hole 32
An eccentric bearing 32 is fitted and rotatably supported with respect to the axis F1 of the axis F1 by an amount shown by the symbol t in the figure. is fitted in such a way that movement in the axial direction is restricted. In addition, a similarly aligning type bearing 35 is fitted into a bearing hole 34 drilled in the frame 1 on the drive side, with its movement in the axial direction being restricted, and the rotation of these bearings 33, 35 on both sides is restricted. By bringing the tip of the pressure regulating bolt 30 into contact with the inner ring, the lever 1
A regulating shaft 36 that regulates the rotation of 6 in the clockwise direction shown in the figure.
is fitted and fixed and rotatably supported on the frame 1. On the other hand, an end shaft 37 on the operation side of the plate cylinder 3 is connected to an outer circumferential circle 3 pivotally supported by the frame 2.
Inner circumferential circle 38 that pivotally supports the shaft center F 2 of 8a and the end shaft 37
It is pivotally supported by an eccentric bearing 38 which is offset from the axis F 3 of b by an amount shown by the symbol t 1 in the figure, and this eccentric bearing 3
By rotating the plate cylinder 8, the operating side and the drive side of the plate cylinder 3 are shifted in phase in the circumferential direction, thereby performing the above-described plate cylinder twist adjustment.
The eccentric bearing 32 on the regulating shaft 36 side and the eccentric bearing 38 on the plate cylinder 3 side are connected by a connecting rod 42 forming a four-bar link 39. That is, a pin 40 and a pin 41 are implanted in the eccentric portion of the eccentric bearing 32 and the eccentric portion of the eccentric bearing 38, respectively, and both pins 40 and 41 have a connecting rod 42 that can be adjusted freely. Both ends are engaged, and the two bearings 32, 38 and the connecting rod 42 form a four-bar link 39. By doing this, when the axis F 3 of the plate cylinder 3 moves by rotating the eccentric bearing 38 and performing twist adjustment, the eccentric bearing 32 connected to the eccentric bearing 38 by the four-bar link 39 moves. Due to the eccentric action of the rotation, the regulation shaft 36 swings around the drive-side bearing 35, and the regulation position of the pressure regulating bolt 30 by the regulation shaft 36 moves by the amount of twist adjustment of the plate cylinder 3.

The eccentricity t 1 and rotation angle are determined, and the position of the plate cylinder 3 at each twist amount is determined by drawing and calculation, and the desired position of the forming roller 28 relative to this is determined. Then, the desired rotation angle change of the lever 16 corresponding to this is determined, and after determining the amount of displacement of the lever 16 at the position of the regulation shaft 36, the eccentricity t of the regulation shaft 36 is determined, and regulation commensurate with the rotation amount of the eccentric bearing 38 is determined. The length of each member of the four-bar link is determined by determining the amount of angular change of the shaft 36. By doing this, the plate cylinder 3
It is possible to design a follow-up device that can maintain the contact pressure between the forming roller 28 and the plate cylinder 3 within a required value that does not approximately change for each twist amount.

することができる。 As explained above, according to the present invention, the regulating shaft, which is supported between both frames and substantially regulates the contact pressure of the forming roller, is supported by one frame via an alignment bearing, and is supported by the other frame. is supported via an alignment bearing and an eccentric bearing, and by connecting this eccentric bearing and the eccentric bearing that supports the plate cylinder with a connecting rod, it follows the axis movement of the plate cylinder due to twist adjustment. Since the axis of the forming roller also moves, even if the plate cylinder is twisted and adjusted after adjusting the contact pressure between the plate cylinder and the forming roller, the contact pressure once adjusted will not change again. Thus, there is no need to re-adjust the contact pressure after twist adjustment, which reduces machine non-operation time and greatly improves productivity. Furthermore, when adjusting the twist of the plate cylinder, both the plate cylinder and the forming roller move around the center in the width direction of the frame, so the synchronization of the forming roller with respect to the plate cylinder is extremely good. Contact pressure changes can be further reduced.
