Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ink fountain device provided in an inking device of a printing press.

The ink fountain of the ink fountain device must be cleaned after removing residual ink during printing color changes and when the machine is stopped for long periods of time.

However, the conventional ink fountain is fixed to the printing machine and cannot be easily removed.

For this reason, conventionally, the remaining ink had to be removed and washed inside a narrow printing press.
There was a problem that the work was difficult to do and the machine stopped for a long time. Furthermore, since the device cannot be removed, cleaning work must be done by wiping it with a rag, resulting in the problem of soiling hands and work clothes.

The present invention was developed in consideration of the above-mentioned problems. By making the ink fountain easily removable from the printing machine, the ink fountain can be easily cleaned outside the printing machine, and color change can also be carried out. In addition to shortening the setup time during printing, it is also possible to easily make fine positional adjustments to the left and right ink stopper side plates, whose tips contact the surface of the ink source roller, relative to the ink source roller. The purpose of this invention is to provide an ink fountain device for a machine.

Embodiments of the present invention will be described below based on the drawings.

In the figure, 1 is an ink source roller, 2 is a base provided near the bottom of this ink source roller 1, and this base 2 is supported so as to be rotatable in the vertical direction of a support shaft 3. 4 is an ink fountain which is close to the ink source roller 1 and is fixed to the base 2;
It consists of left and right ink stop side plates 5, 5, a doctor 6 forming the bottom plate of the ink fountain 4, and a doctor holder 7 fixed to the underside of the doctor 6, which are assembled and fixed as one piece. In particular, the ink stopper side plates 5, 5 are brought into contact with the side end surface of the doctor holder 7, and are fixed with bolts (not shown).

The dot holder 7 of the ink fountain 4 is provided with cutout grooves 8, 8 which are open on the ink source roller side. The notch grooves 8, 8 have a stepped shape that is larger on the upper surface side. Also, the base 2 has through holes 9, 9.
The through holes 9, 9 are provided with a large diameter portion 10 that engages with the stepped portion of the notch grooves 8, 8 at the head portion, and a large diameter portion 10 that engages with the step portion of the notch grooves 8, 8 on the other portion, and a large diameter portion 10 that loosely fits into the narrow portion of the notch grooves 8, 8 at the other portion. A fixing pin 12 having a small diameter portion 11 is fitted therein. A female thread is provided at the lower end of the fixing pin 12, and a screw 14 of the lever 13 is screwed into this female thread. 15 is a collar, 16 is a receiving plate, and 17 is a metal fitting for preventing rotation of the fixing pin 12.

In the above structure, the ink fountain 4 is fixed to the base 2 by engaging the fixing pin 12 in the notched grooves 8, 8 of the doctor holder 7, and tightening the fixing pin 12 with the lever 13. Also lever 1
3 loosens the engagement between the fixing pin 12 and the doctor holder 7. In this state, by pulling out the doctor holder 7 in the direction of the arrow, the entire ink fountain is separated from the base 2.

Furthermore, when the ink fountain 4 is fixed, the tips of the ink stopper side plates 5, 5 are brought into contact with the surface of the ink source roller 1 without any gaps.
Adjust the position of the doctor holder 7 with respect to the doctor holder 7. This position adjustment is performed by loosening the bolts fixing the ink stopper side plates 5, 5 to the doctor holder 7, and allowing only the play of the bolt holes with respect to the bolts.

The present invention is as described above, and ink stopper side plates 5, 5 whose tips contact the surface of the ink source roller 1 are bolted to both sides of the doctor holder 7 that fixes the doctor 6, and Providing cutout grooves 8, 8 that open on the original roller side,
Further, since the base 2 supporting the doctor holder 7 is provided with a fixing pin 12 that engages in the notch grooves 8, 8 in the axial direction and can be compressed in the axial direction, the ink fountain can be compressed by retracting the fixing pin 12. The entire ink fountain 4 can be easily removed from the doctor holder 7 in the direction away from the ink source roller 1, making it possible to clean the ink fountain 4 in a wide area when changing colors or when the printing machine is stopped for a long time. The ink fountain cleaning machine can be used to easily clean the ink fountain without staining hands or work clothes. Further, when changing colors, printing can be started simply by replacing the ink fountain 4 with another one, and the setup time when changing colors can be shortened. Furthermore, according to the present invention, ink stop side plates 5, 5 forming the side wall of the ink fountain 4 are provided.
By fixing it to the side of the doctor holder 7 with bolts, it is possible to adjust the position of the ink stop side plates 5, 5 with respect to the ink source roller 1 by the amount of play in the bolt connection part, and the ink stop side plates 5, 5 can be Make fine adjustments to the original roller 1 using the doctor holder 7.
It can be easily done separately.

[Brief explanation of the drawing]
