Abstract

PROBLEM TO BE SOLVED: To wash the inner surface of an ink fountain by bonding a cover film to the inner surface of the ink fountain at a time of use and merely replacing the same with a new cover film. SOLUTION: A film having a bottom surface protecting part 15a covering the bottom surface 7a of the inner surface of an ink fountain and the flap parts 15b connected to both sides thereof is used as the cover film 15 bonded to the inner surface of the ink fountain. The flap parts 15b have the side surface protecting part 15b1 covering the side surface 10a of the ink fountain and the surplus part 15b2 held between a fountain roller 3 and the end surface of the side plate 10 of the ink fountain and, in such a state that the cover film 15 is attached to the ink fountain, the cover film 15 covers not only the bottom and side surfaces of the ink fountain but also the end surface of the side plate 10 of the ink fountain and the cover film 15 contaminated by the remaining ink 20 is replaced with a new one to simply remove the ink contamination in the ink fountain.

2. Description of the Related Art An ink fountain system is usually used for supplying ink in an offset printing machine or a letterpress printing machine, and ink in the ink fountain is supplied to an original roller (also referred to as a fountain roller).
Is supplied to an ink mixing roller via a call roller, and after being kneaded by a number of ink mixing rollers, is supplied to a plate cylinder. At this time, in order to adjust the ink supply amount according to the pattern, a number of ink keys are arranged side by side at the bottom end of the ink fountain (the position facing the original roller). The ink supply amount is adjusted by changing the gap.

[0003] In such an inking device, when a printing item is changed, a used ink fountain must be cleaned thoroughly. If new ink is added in an insufficiently washed state, it mixes with old ink and cannot accurately reproduce color. Therefore, careful washing is necessary especially when changing from dark to light. In addition, if the cleaning is insufficient, the ink may enter between the ink keys and dry, resulting in a malfunction of the key. Therefore, careful cleaning is necessary also from this point.

[0004] Cleaning of the inking unit is roughly divided into roller cleaning and ink fountain cleaning. Generally, in roller cleaning, the printing press is put into an operating state, a cleaning liquid is applied to a roller group, and a cleaning liquid mixed with ink is collected by a doctor. Roller cleaning is becoming more automated, and these operations can be performed automatically in many printing presses. On the other hand, the cleaning of the ink fountain is difficult to automate due to the complicated shape of the ink fountain, and is performed manually in almost all printing presses.

Several methods have been proposed for automating the cleaning of the ink fountain, but a relatively simple and realistic method is to cover the ink fountain and the ink key with a cover film and replace the cover film during cleaning.

However, the cover film proposed in the prior art covers only the bottom surface of the ink fountain, so that the side surface of the ink fountain cannot be protected. Cleaning is performed by hand or a small cover film dedicated to the side of the ink fountain is pasted on and then removed by hand. For this reason, even if a cover film is used, there is a problem that it is difficult to improve the efficiency of the cleaning operation, and the merit is small.

In the ink fountain cover film having the above structure, the bottom surface protection portion is disposed so as to cover the bottom surface of the ink fountain and the ink key at the lower end thereof, and the side protection portions of the flap portions on both sides are provided on the side surfaces of the ink fountain (the inner surface of the ink fountain side plate). Not only covers the entire inner surface of the ink fountain, including the ink key, but also covers the entire area of the inner surface of the ink fountain, including the ink key, by placing a margin between the original roller and the end face of the ink fountain side plate. It can also cover the pressed end surface well and protect it from ink contamination.When washing for color change, replace the ink fountain cover film with a new one to remove ink stains on the inner surface of the ink fountain. This eliminates the need for the manual ink fountain cleaning operation that was conventionally performed. In addition, since the ink fountain cover film has a single-sheet structure, replacement work is easy, and the work load on the operator can be reduced.

1 to 6, a cover film 15 is attached to the inner surface of the ink fountain. As shown in FIG. 4, the cover film 15 is obtained by cutting a single film into a shape having a bottom surface protection portion 15a and flap portions 15b formed on both sides thereof. Here, the bottom surface protection portion 15a has a width and a length capable of covering substantially the entire area of the bottom surface 7a of the ink fountain and the ink key 8 at the lower end of the ink fountain in the inner surface of the ink fountain.
More specifically, it has substantially the same width as the ink fountain bottom surface 7a and is slightly longer than the ink fountain bottom surface 7a (for example, 1 to 1).
0 cm). Further, the flap portions 15b formed on both sides of the ink fountain are connected to the ink fountain side surfaces 10a.
The side protection section 15b 1 substantially triangular covering the surface (inner surface of the ink fountain side plate 10), a margin portion 15b provided subsequently
It consists of two Prefecture, the margin portion 15b 2 is for being sandwiched between the end face 10b of the ink fountain side plate 10 opposite thereto with fountain roller 3. Therefore, the side surface protection portion 15
b 1 has an area equal to or larger than the ink fountain side surface 10 a, and the margin 15 b 2 has an area equal to or larger than the end face 10 b of the ink fountain side plate 10.

Next, the operation of the ink fountain device 2 having the above configuration will be described. At the time of normal printing, the ink fountain main body 7 and the ink fountain side plate 10 are shown in FIGS.
The cover film 15 occupies the operating position shown in (a) and the like, and covers the inner surface of the ink fountain. That is, the bottom surface protection portion 15a (see FIG. 4) of the cover film 15 covers the ink key 8 and the ink fountain bottom surface 7a.
Side protective portion 15b 1 of the 5b are covering the ink fountain side 10a, it is sandwiched between further margin portion 15b 2 of the ink fountain side plate 10 and the fountain roller 3 and the cylindrical member 30. Printing is performed in this state. That is, in FIG. 1, the original roller 3 slowly rotates in the direction of the arrow, and the ink supplied into the ink fountain forms an ink film on the outer peripheral surface of the original roller 3, and the ink contacts the original roller 3. The ink is supplied to the inking roller 4 which has been moved to the position, and then the inking roller 4 is moved to a position where it contacts the inking roller 5 to transfer the ink to the inking roller 5.

During this operation, the ink fountain main body 7 and the ink fountain side plate 10 are not stained with the ink because the inner surface of the ink fountain is covered with the cover film 15 as well as the bottom surface. Further, since the original roller 3 rotates, the extra portion 15b 2 of the cover film 15 sandwiched between the original roller 3 and the ink fountain side plate 10 may be pulled by the original roller 3, but this extra portion 15b 2 is sandwiched and fixed between the non-rotating cylindrical member 30 and the ink fountain side plate 10, so that the cover film 15 does not move and cause trouble. The cover film 15 has good slipperiness, and the cylindrical member 30 and the ink fountain side plate 1
0 and even without fixing the margin portion 15b 2, if there is no possibility that the margin portion 15b 2 in contact with the fountain roller 3 is pulled by the fountain roller 3, the cylindrical member 30 may be omitted.
