Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of an ink fountain device for a printing press.

Conventionally, according to Japanese Patent Application Laid-open No. 52-51211, an upper flat plate that also serves as a bottom plate and a presser plate (in the same publication,
20) is fixed with bolts 23 and 26, but this type has the drawback that it takes time and effort to remove and install the bolts 23 and 26 when removing the upper flat plate, making it difficult to use.

In order to eliminate these deficiencies, this invention
The bottom plate and the holding plate are integrated to form an ink reservoir, and the structure has a magnet and an engaging part, which makes attachment and detachment extremely easy. The purpose of the present invention is to provide an ink fountain device for a new printing press that is designed to improve the adhesion of the keys and the ink fountain keys, and to keep the operating resistance of the ink fountain keys appropriate and constant. do.

To achieve this purpose, the ink fountain device according to the present invention is surrounded by an ink fountain roll 1 at the front, a pair of side blocks 2, 2' at both left and right sides, and an inclined bottom plate 3 at the rear and bottom. In addition, a funnel-shaped ink pot 5 has an ink delivery slit 4 formed between the front edge of the bottom plate 3 and the outer circumferential surface of the ink pot roll 1 by the surrounding, and the tip of the ink delivery slit 4 is formed between the front edge of the bottom plate 3 and the outer peripheral surface of the ink pot roll 1. Bottom plate 3
A large number of ink fountain keys 7 closely cross the front edge of the ink fountain roll 1 and touch the outer peripheral surface of the ink fountain roll 1, and these ink fountain keys 7 can be moved from above and below in a state where they can be moved from above and below in a state where they can be moved from above and below. In the ink fountain device of a printing press, the bottom plate 3 and the presser plate 10 and the operating device 11 for distance and contact movement of each ink fountain key 7 are arranged as required in the machine body 12. The integrated object 14 is placed on the ink fountain key 7 with the holding plate 10 integrated, and the integrated object 14 and the body 12 are fitted together by the operation of placing the integrated object 14 on the body 12. An engaging portion is provided to prevent back and forth and left and right movement, and a side magnet 19 is provided to attract the other contact surface to one contact surface of the mutually contacting surfaces of the side block 2 and the ink fountain key 7 and the adjacent ink fountain keys 7. , an upper magnet 17 that attracts the other contact surface to one of the contact surfaces of the holding plate 10 and the ink fountain key 7 that contact each other is attached to one of the surfaces of the base plate portion 8 and the ink fountain key 7 that contact each other. A downward magnet 18 for attracting the other contact surface is embedded in each contact surface. Since the present invention has the above-described structure, when disassembling the ink bottle 5 for cleaning etc. due to ink color change, the integrated body 14 is removed after draining the ink from the ink bottle 5.
After applying a pulling force to the ink bottle key 7 and removing the engaging parts 15 and 16 and releasing the upper magnet 17 from adhesion, move the integrated object to another place where it will not get in the way, and then pull out the ink fountain key 7. Also, when assembling, you can just follow the above steps in reverse, and if you follow these steps, there is no need to remove or tighten bolts, etc.
It has the advantage that it can be disassembled and assembled easily and easily.Furthermore, in the present invention, the integrated object 14 is prevented from moving back and forth and left and right by the engaging parts 15 and 16, and is lifted up by the attraction of the upper magnet 17. In addition, the ink fountain key 7 has upper, lower, and side magnets 17, 18,
19 provides an appropriate and constant adsorption force, so there is no ink leakage.Furthermore, the upper, lower, and both sides of the ink fountain key 7 are provided with magnets 17, 18, and 18 when assembled. 19, the operating resistance of the ink fountain key 7 is always kept constant and the ink fountain key 7 has good operability.

In the first embodiment shown in FIG. 1, the front surface is surrounded by an ink fountain roll 1, the left and right sides are surrounded by a pair of side blocks 2, 2, and the rear and bottom surfaces are surrounded by an inclined bottom plate 3. A funnel-shaped ink pot 5 having an ink delivery slit 4 formed between the front edge of the ink pot roll 1 and the outer peripheral surface of the ink pot roll 1 is constructed on the body 12, and the tip of the ink pot 5 is provided on the body 12. A large number of ink fountain keys 7 traverse the lower surface of the delivery slit 4 in close contact with the front edge of the bottom plate 3 and contact the outer circumferential surface of the ink fountain roll 1 from a distance. A base plate part 8 and a presser plate 10 are provided, which are clamped in a state where they can be moved near and far and in contact with each other.
0 and the above-mentioned bottom plate 3, and the integrated object 14 is simply placed thereon, and the integrated object 14 and the fuselage 12 are fitted into each other by the operation of placing the integrated object 14 on the fuselage 12. An engagement shaft 15 and an engagement bearing 16 are provided to prevent back and forth movement, and an engagement bearing 16 is provided, and an upward magnet 17 is provided on one of the mutually contacting surfaces of the presser plate 10 and the ink fountain key 7 to attract the other contact surface. Furthermore, a downward magnet 18 is attached to one of the mutually contacting surfaces of the base plate portion 8 and the ink fountain key 7 to attract the other contact surface to the other contact surface, and a downward magnet 18 is further attached to the mutually contacting surface of the ink fountain key 7. Side magnets 19 for attracting the other contact surface are embedded in one contact surface of the fuselage 12.
At the rear of each ink fountain key 7, a fulcrum holder 21 that moves forward and backward, and an adjusting body 22 that moves forward and backward in the same way are installed in an up-and-down arrangement so that they cannot be rotated by a key 22', etc., and these fulcrum holders 21. A link 23 is arranged vertically between the front ends of the adjustment body 22, and the base end of the link 23 is supported by a fulcrum shaft 24 on the fulcrum holder 21 so as to be able to swing freely in the front and back direction, and the free end of the link 23 is The rear surface is always pressed against the front end surface of the adjusting body 22 by a pusher 28 composed of a spring 26 and a guide bush 27 via a first idler ring 25, and the link 23
