Description

[Detailed description of the invention] The purpose of this invention is to enable quick and large-volume printing on the peripheral walls of cylindrical objects such as writing shafts and confectionery containers, and to contribute to improving product quality and productivity. This relates to printing equipment for cylindrical containers.Printing technology is constantly progressing, but as the quality of products increases, there is a strong demand for improved productivity and speed amplifiers for production lines, and recently there has been an increase in production speed. There is a growing demand for technological development that fully takes energy and resource conservation into account, including measures to prevent line pollution.

By the way, one of the basic technologies for curved surface printing, which is used to print the peripheral walls of cylindrical containers such as writing shafts and confectionery containers, is the drying technology of inks and coatings, which converts these coatings from fluids to solids. The drying process of printing has a fundamental connection with the above-mentioned quality productivity, pollution control, energy saving, and resource saving.

Therefore, the new technology that meets this demand is one that will lead to a new curing and drying technology.

This idea was developed with the advent of ultraviolet curable ink, which is cured by ultraviolet rays instead of the conventional natural drying methods such as penetration, oxidation, volatilization, and thermal reactions. Conventionally, the cylindrical container Ellll is transferred to a drying place after printing is completed, dried for over 20 hours, and then taken in and further coated before being shipped.

This had disadvantages, such as requiring a large number of people, resulting in uneven quality, and a decrease in product value. However, this idea was very successful in that printing and drying could be done at the same time. This method eliminates the drawbacks of the conventional method, such as reducing the number of personnel and reducing production costs, as well as eliminating uneven quality.

This relates to a printing device for containers.

Incidentally, the straight tube-shaped light bulb 10 has small gears 18 and 18 rotating as the handle 1γ rotates, and a straight tube-shaped light bulb 1 at the top.
The vertical ranks 19, 19 to which 0 is attached move up and down, and the straight tube-shaped light bulb 10 is moved up and down to adjust the illuminance according to the cylindrical body 15.

... mesh with each other, the mounting rotating bodies 6, 6... automatically rotate, the cylindrical body 14 rotates, and the printed cylindrical body 14 is rotated.
The printing surface can be cured quickly, and the printing process can be carried out in large quantities at low cost.

Further, since the printing ink is the above-mentioned ultraviolet curable ink and the straight tube-shaped light bulb 10 generates ultraviolet irradiation energy, the straight tube-shaped light bulb is installed in such a way that the longitudinal direction is parallel to the axis 4, 4, etc. ..., which is the traveling direction of the printed cylindrical body 14, and the printed cylindrical body 14 must be held in a direction perpendicular to the straight tube-shaped light bulb and run at a constant speed by the endless checker 73. The surface of the printed cylindrical body 140 is irradiated with ultraviolet rays generated from a straight tube-shaped light bulb 10 that is formed long along the direction of movement of the cylindrical body 14, which moves while rotating as the cylindrical body 14 advances. Energy cylindrical body 1
A cylindrical body 14 printed with ultraviolet curable ink that can be applied evenly while moving under a straight tube-shaped light bulb.
The surface of the cylindrical body 14 is uniformly hardened to prevent damage and deterioration of the material of the cylindrical body 14 and to promote hardening of the printed surface. This process is taken in, coated, and then shipped, which requires a large number of personnel, resulting in uneven quality and a decline in product value. A ventilation gap is provided between the parallel shafts 4, 4, which are provided parallel to the chains 73, 3, and a mounting rotating body 6, on which both ends of the printed cylindrical body 14 are placed. 6
A mounting gap b7 with a ventilation gap is provided between them, and a rectangular shape with a straight tube-shaped light bulb 10 located inside thereof is provided, with the opening on the lower surface being close to between the upper chain horizontal parts 9, 9. Opposing umbrella bodies 11 are provided oppositely, and an exhaust pipe 16 is provided at the upper part of the umbrella body 11.
By providing this, when the printed surface is cured, the air contacts the entire circumferential surface of the cylindrical body 14 and ensures an upward flow, so that the cylindrical body 14 is heated by the heat of the light bulb 10 with this flowing air. Coupled with reducing the temperature rise, the impure gas generated during curing does not flow into the workplace, preventing it from becoming a health hazard for workers, and it also moves while rotating beneath the straight tube-shaped light bulb 10. cylindrical body 1
This prevents only one side of the circumferential wall surface from being heated, which prevents deterioration in quality such as deformation of a cylindrical container made of synthetic resin such as a writing shaft due to temperature.

Further, the mounting rotary bodies 6, 6, which are located inside the endless chains 73, 3 and have a protruding flange plate 5°5, are connected to a large number of parallel shafts 4,
4... are provided opposite to each other, and further a printing device body 13 is provided.
Both ends of the cylindrical body 14 printed on the peripheral wall surface are placed and guided between the mounting rotary bodies 6, 6 with the flange plate 5 protrudingly provided, and between the mounting rotary bodies 6, 6 with the flange plate 5 protrudingly provided. By providing the placement guide piece 15, the cylindrical body 14 printed on the peripheral wall surface by the printing device body 13 can be stably positioned between both ends of the cylindrical body 14 between the mounting rotary bodies 6, 6 and between the mounting rotary bodies 6, 6. Since the surface that is placed and printed by the printing device body 13 does not directly touch the placement rotating bodies 6, 6, 6, 6, the printed surface does not come into contact with other objects and get dirty before it hardens. The cylindrical container placed on the mounting rotary body 6, 6, 6°6 is prevented from falling off by the collar plates 5, 5, and the moving speed of the endless checker 73, 3 is adjusted according to the printing processing capacity of the printing device body 13. The cylindrical body can be rotated 140 times and transferred efficiently.

Therefore, the surface of the printing surface of the cylindrical body can be hardened evenly on the average, resulting in a beautiful printing surface, while also preventing troubles such as deformation or material change of the cylindrical body due to heat. It is possible to prevent staining or falling off of the printed surface of the object, improve product quality and productivity, or reduce printing costs by speeding up the production line, preventing pollution, and reducing labor costs. It has a simple structure and has many practical effects, such as being able to withstand long-term use without fear of failure.
