Abstract

PROBLEM TO BE SOLVED: To tone and simultaneously fill in a can container printing ink of a desired color by mixing a plurality of printing ink base colors in a predetermined ratio with no need for a hand or cleaning accompanying a color change by providing moving equipment to move arbitrarily a can container to a filling nozzle position. SOLUTION: A metal can 30 carried by a carrying line 43 is moved onto a turn table 40 by a can push out machine 44. Then by the rotation of the turn table 40, the can opening of the metal can 30 is placed directly under the discharge opening of the filling nozzle 20 of a predetermined color ink base, and the ink base is dropped from the discharge opening. The amount of the ink base filled is detected by a detector 32, and when the amount reaches a value set in advance, the filling stops. Then by rotating the turn table 40, the can is moved and is placed under the filling nozzle 20 of a color to be filled next, and then a predetermined amount of ink base is filled. After all the ink bases are filled, the can is discharged to the carrying line 43 from moving equipment 42 by a can push out machine 45.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toning and filling apparatus for mixing a plurality of printing ink bases in a predetermined ratio and toning a desired color of printing ink and filling the toned container at the same time.

[0002]

2. Description of the Related Art Conventionally, when making a special color with an aqueous printing ink such as a flexographic ink, an ink base of about 10 to 20 colors is prepared, and a predetermined amount of the ink base of 3 to 5 colors is usually prepared. They were weighed into a mixing container, toned by mixing, subdivided into 18-liter cans, and shipped. However, this method requires skill for fine adjustment of hue. Further, since it is necessary to clean the mixing container every time the color is changed, human labor is required, and equipment for wastewater treatment is also required.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for toning and filling a water-based printing ink which does not require any manpower and does not require washing accompanying color change.

[0004]

SUMMARY OF THE INVENTION The present invention comprises a plurality of supply tanks containing ink bases of different hues, and a number of filling tanks for filling the ink bases in a number corresponding to the number of the supply tanks. A nozzle, a pipe through which the ink base circulates between the supply tank and the filling nozzle, a detector for detecting the amount of the ink base filled in the can container in a gravimetric manner, and And a moving device that moves to the filling nozzle position.

Further, the present invention relates to the above-mentioned toning filling apparatus in which a plurality of filling nozzles are arranged on the same circumference.

Further, the present invention relates to the above-mentioned toning and filling apparatus in which the inner surface of the discharge port of the filling nozzle is not in contact with air when not filled with a plug member.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A supply tank 10 stores an ink base in a container having an open top, and a lid 12, a pump 12,
A discharge pipe 14 for supplying the ink base to the filling nozzle 20 via the pipe 13 and a pipe 16 for returning the ink base to the original supply tank 10 through the pipe 15 are provided. Further, a leveling meter 17 is provided on the lid member 11 so that when the liquid level of the ink base falls below a predetermined liquid level, a warning is issued or filling is stopped. The number of supply tanks is equal to the number of ink bases, for example, about 5 to 20.

[0008] The filling nozzle 20 is configured such that an ink base passing through an inlet 23 from a discharge pipe 22 opened by pulling up a plug member 21 connected to a filling nozzle actuator 35 is supplied from a can opening 31 of a can container 30 to a metal. It flows out into the can 30. The plug member 21 is brought into close contact with the inner wall surface of the discharge pipe 22 when the filling operation is not performed, thereby preventing the water-based ink from drying and forming an ink film inside the discharge pipe. Excess ink base is returned to the original supply tank 10 through the outlet 24. The amount charged in the can 30 is detected by a detector 32 incorporating a load cell. When there are many filling nozzles, these filling nozzles are arranged on the same circumference at equal intervals. A turntable with almost the same circumference underneath
A moving device 42 having 40 and power 41 is arranged. A support 25 supporting the filling nozzle actuator 35 is provided on the turntable 40, and the filling nozzle actuator 35 moves as the turntable 40 rotates. The filling nozzle actuator 35 is provided with a member 36 having a partially open mouth shape, and when the metal can is moved to the filling position, the projection 27 of the filling nozzle 20 is placed in the mouth-shaped space of the member 36. To be located.

[0009]

[Function] The metal can carried on the transport line 43 is a can extruder
It stops before 44, and then moves onto the turntable 40 by the can extruder 44. Next, the metal can is set so that the can opening 31 of the metal can comes under the discharge can 22 of the ink-based filling nozzle 20 of a predetermined color by rotating the turntable. At this time, the protrusion 27 of the filling nozzle 20 is located in the mouth-like space of the member 36 of the filling nozzle actuator 35. When the filling nozzle actuator 35 is actuated by air pressure, the plug member 21 of the filling nozzle is pulled up, and the ink base flows down from the discharge port 22. The amount of the filled ink base is detected by the detector 32, and when the amount reaches a preset value, the filling is stopped. At this time, when the value falls within a certain range from the set value, the plug member is lowered slightly to reduce the amount of the ink base flowing out, thereby improving the accuracy of the filling amount.

The metal can filled with the base ink of the first color is moved by rotating the turntable under the filling nozzle of the ink base of the next color to be filled with a predetermined amount of the base ink. You. Filling is performed for the ink base of another color by the same operation as described above. When the filling of all the ink bases is completed, the ink is discharged from the moving device 42 to the transport line 43 by the can extruder 45. The above series of operations are programmed in advance and can be monitored on a control panel (not shown). Based on the filling, the metal can is mixed uniformly by shaking the entire can, etc., to complete the toning.
