BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an expansion management tool for an inking roller in a sheet-fed printing press.

[0002]

2. Description of the Related Art In printing, the inking roller gradually expands in heat during the operation of the machine, and the distance between the inking roller and the plate cylinder on which the printing plate surface is attached becomes closer, which causes too much ink to be deposited. It is necessary to prevent this in advance, and this is done by controlling the distance between the inking roller and the plate cylinder. Conventionally, such operations are managed based on the experience and intuition of the person in charge of printing, but it is difficult to always perform reliable expansion management. Further, there is a device whose operation is controlled by an electric device or a mechanical device attached to it, but it is generally a large-scale and expensive device, and in terms of the cost of printing and a printing machine. It is a problem that needs to be considered.

[0003]

In this invention, the conventional inking roller described above gradually expands in heat, and the distance between the printing cylinder and the plate cylinder on which the printing plate surface is attached becomes close, so that a large amount of ink is generated. The purpose is to easily control the excessive arrival with a relatively simple device.

[0004]

[Means for Solving the Problems] The support (2) or the rotating body (2 ') is attached to the frame, and the marker plate surface (3) is attached to the support (2) and the rotating body (2'). , Over the entire width of the marking plate (3), inclined heading pieces (a1), (a2), (a3), etc. having different heights are sequentially arranged from one direction to the other direction, The expansion control tool (A) of the inking roller (C) is characterized in that it is installed on the plate cylinder (B) in contact with the inking roller so that it rotates together with the plate cylinder (B).

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION A support (2) or a rotating body (2 ') is attached to a frame, a marking plate surface (3) is attached to the supporting body (2) and the rotating body (2'), and the marking plate surface ( Ink the expansion control tool (A) in which inclined heading pieces (a1), (a2), (a3), ... It is installed on the plate cylinder (B) that comes into contact with the roller (C) so that it rotates with the plate cylinder (B).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, the expansion control tool (A) of the present invention (inking roller) has a support (2) attached to the upper part of a frame (1). It is installed on the plate cylinder (B) described later, and its support (2) rotates together with the plate cylinder (B). The plate (3) is attached to the support (2), and its structure is, as shown in Fig. 2, directed from one direction to the other over the entire width thereof, and the sloped pieces with different heights are sequentially arranged. (a1), (a2), (a3) ... Are arranged. FIG. 3 shows another embodiment of the present invention, in which the rotary body (2 ') is mounted in the frame (1') of the expansion management tool (A). Around the rotator (2 '), several sets of marking plates (3) are attached. This rotating body (2 ') rotates together with the plate cylinder (B) as described above. FIG. 4 (a) is a front view of the rotating body (2 ′), and FIG. 4 (b) shows the side surface of FIG. 4 (a). Further, FIG. 4C shows a modification of the inclined heading piece attached to the marker plate surface (3). FIG. 5 shows the arrangement of the plate cylinder (B) and the inking roller (C), and the expansion control tool (A) is installed on the plate cylinder (B) as described above. Fig. 6 shows the expansion cylinder (A) installed on the plate cylinder (B). The plate cylinder (B) is provided with printing plate surfaces (D) and (D ') with marking marks (d) to be printed [the plate surface can be any number]. The ink from the application roller (C) will be attached to the printing plate surfaces (D) and (D '), but the initial height of the entire marker plate surface (3) of the expansion management tool (A) is the most. Align the high-inclined heading pieces (a1) flush with the printing plate surfaces (D) and (D ').

By the operation of the printing machine, initially, only the slant heading pieces (a1) and (a2) of the marker plate surface (3) of the expansion management tool (A) come into contact with each other, which causes the margin of the printing paper (P), etc. FIG. 7A shows a state in which the management marks (a'1) and (a'2) are printed on the screen. When this state is set to an appropriate state, in Fig. 7 (b), the inking roller (C) gradually expands due to the rotation, and the plate cylinder (B) is also affected by the heat, and the inking roller (C) gradually increases. When the distance between C) and the plate cylinder (B) becomes close, and the ink adheres excessively, the inclined heading piece (a3) of the marker plate surface (3) of the expansion management tool (A) is printed, The management marks (a'1), (a'2), and (a'3) are printed. The distance between the inking roller (C) and the plate cylinder (B) can be determined by visually recognizing the number and size of these slanted heading prints, and thus the appropriate distance between the two. That is, it is possible to easily control the proper ink adhesion by adjusting the proximity.

[0008]

EFFECTS OF THE INVENTION The present invention [1] enables a beginner to easily and surely perform expansion control of the ink form roller, which has conventionally depended on the experience of the operator. [2] Since the degree of expansion of the ink form roller can be grasped at a glance, the adjustment time of the printing machine is shortened and the workability is improved. [3] Since the expansion control of the inking roller can be performed reliably, it is possible to prevent stains on the printing plate surface due to excessive adhesion of ink and image breakage due to insufficient ink, which contributes to stable quality of the printed matter.
