Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inking roller device for an offset printing press.

In the case of the above-mentioned ink form roller device, in order to make the device more compact, it is installed inside the printing press frame.

2. Description of the Related Art Conventionally, the inking roller devices shown in FIGS. 1 to 3 are known as inking roller devices that are attached to the inside of a frame as described above.

That is, what is shown in FIG.
and the axes b and b are fixed on the same axis by bolting or the like, and in the case shown in Figs. 2 and 3, the rollover drive mechanism c is mounted outside the frame d on the operating side or on the non-operating side. It is formed so as to protrude from one or both of the above.

However, with each of the above-mentioned configurations, there are problems in that not only does the device become large, but it is also troublesome to attach and remove the rollers.

Therefore, as a result of studies in view of the above-mentioned conventional problems, the present invention has been developed to create an inking roller device that is designed to be compact and easy to assemble and disassemble. be.

The present invention will be described in detail below based on the illustrated embodiments. As shown in FIGS. 4 and 5, a frame 1
A housing 3 is fitted through a mounting hole 2 formed through the housing 3, and is fixed to the frame 1 with bolts 4, etc., and a rolling roller 5 is rotatably supported on the housing 3 via bearings 12. . A bracket 6 is externally supported on the small-diameter portion 3a of the housing 3 that protrudes from the inner surface of the frame 1, and a mounting portion 6a provided at one end of the bracket 6 is attached to the bracket 6, and the roller 7 is mounted directly or as shown in the figure. The bracket 6 is rotatably supported via a block 8 as shown in FIG. The inner diameter L of the mounting hole 2 is larger than the outer diameter l of the rolling roller 5, so that the rolling roller 5 can be inserted into and removed from the mounting hole 2.

Here, the forming roller 7 has a bearing 9 fixed to the end of its shaft 7a, and the bearing 9 is fixed to the end of the shaft 7a.
is fixed to the block 8 by a bearing holder 11 which is fixed with a screw 10, and is rotatably supported by the block 8 with no play in the axial direction. The mounting portion 6a of the bracket 6 is formed into an annular shape, and the opening width a of the cutout portion 6b is larger than the outer diameter of the rolling roller shaft 5a.

In the above configuration, when installing this to the frame 1, first insert the rolling roller 5 through the mounting hole 2 of the frame 1, then insert the shaft 5.
A housing 3 is mounted on the exterior of the housing 3, and the housing 3 is fitted into the mounting hole 2 of the frame 1, and is fixed to the frame 1 with screws 4, thereby assembling the rolling roller 5.

Next, insert the bracket 6 laterally to the shaft, insert the shaft portion between the rolling roller 5 and the inner end of the housing 3 into the notch 6b of the mounting portion 6a,
Next, the bracket 6 is moved to the right in FIG. 5, the mounting portion 6a is mounted on the inner end 3a of the housing 3, and the bracket 6 is assembled. Next, the bracket 6 is attached to support the roller 7, and the assembly is completed.

When removing this, first remove the housing 3 from the mounting hole 2 of the frame 1. When the housing 3 is removed in this way, only the rolling roller shaft 5a is present in that part, so if the shaft 5a is then aligned with the notch 6b and the bracket 6 is pulled in the direction perpendicular to the shaft 5a, Notch 6
By doing b, the bracket 6 can be removed with the block 8 still attached.

Next, attach the rolling roller 5 to the mounting hole 2 of the frame 1.
Removal is completed by pulling it out.

As explained above, since the ink forming roller device of the printing press according to the present invention is configured,
Although it is installed inside the printing press frames 1, 1, the overturning roller 5 can be inserted and pulled out from the mounting hole 2 of the frame 1, and can also be installed in the housing 3 for installing the overturning roller. The mounting roller mounting bracket 6 can be attached and removed while aligning the notch 6b provided on one side of the mounting portion 6a with the rolling roller shaft 5a, making disassembly and assembly easy and quick. Furthermore, the device only requires that the housing mounting hole 2 of the frame 1 is formed larger than the outer diameter of the rolling roller 5, and that a notch 6b is provided on one side of the mounting portion 6a of the bracket 6, and other special members are attached. Since it is not a physical object, the structure can be simplified and manufactured at low cost, and the device can be made smaller.
