Abstract

PURPOSE:To prevent the intrusion of air into a treating space for a beltlike body and the outflow of an atmosphere maintaining substance to the outside of the space, and to reduce running cost by collecting outlets and inlets to the treating space to one position and adjoining the entering beltlike body and the going-out beltlike body. CONSTITUTION:In a beltlike body treating device 2, which fills a space surrounded by a wall 2' with an atmosphere maintaining substance 11 such as an inert gas and maintains the space in an atmosphere different from the outside air and makes a beltlike body (such as a print) 9 travel in said space and processes and treats it (for example, it is dried and treated by an electron ray projector 3), an inlet section and an outlet section to the space for said beltlike body 9 are collected to one position and used as an outlet and inlet section 8 while the entering beltlike body and the going-out beltlike body are adjoined. EFFECT:The intrusion of air 12 and the outflow of an atmosphere maintaining substance 11 are prevented because the beltlike body 9 going in and out in an outlet and inlet section 8 adjoin and travel in the opposite direction. USE:The titled device is employed for a drier, etc. for a printing machine.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a strip processing device for processing a strip running in a dryer of a printing machine, a coating machine, or the like.

The apparatus for drying printed matter printed with ink using electron beam curing resin had a table structure as shown in FIG. In the figure, 1 is a printing unit.

2 is an electron beam curing device, and 9 is a printed material. The electron beam curing device 2 has a box-shaped structure whose periphery is sealed with walls, and has a slit-shaped entrance portion 5. An outlet portion 6 is formed. An electron beam irradiation device 3 is installed opposite the travel path of the printed material 9.

15 is a guide roll that guides the printed matter 9. Since the curing of electron beam curing resin is inhibited by the presence of oxygen during curing, inert gas such as nitrogen is supplied from the supply port 4 to fill the inside of the electron beam curing device 2 with the inert gas. There is a need. In the inlet section 5, an inert gas 1o is flowed toward the outside in order to prevent air entrained in the printed matter 9 from entering. Further, at the outlet, an inert gas 11 flows out accompanied by the printed matter 9. As described above, this apparatus has the disadvantage that a large amount of inert gas such as nitrogen flows into the air, resulting in high operating costs.

The present invention provides a strip processing apparatus that maintains a space surrounded by walls in an atmosphere different from the outside air, and processes a strip by running the strip within the space, in which an inlet and an outlet of the strip are connected to the space. It is characterized by having the incoming and outgoing strips brought together in one place, and the incoming and outgoing strips are brought close to each other.The purpose of this is to eliminate the above-mentioned drawbacks of the conventional methods and to reduce the amount of material consumed to maintain the atmosphere in the space. The present invention aims to provide a strip processing device that can reduce operating costs.

The present invention is configured as described above, and the air that is about to enter the band-like body at the entrance and exit part of the band-like body and the substance that maintains the atmosphere in the space that is about to flow out together with the band-like body are separated. Since they collide with each other, there is almost no air inflow.

In addition, the outflow of material is almost forceful, and a trench is created.
Less material consumption and lower operating costs.

The present invention will now be explained in detail with reference to the most preferred embodiment shown in FIG. In this embodiment, the present invention is applied to an electron beam curing apparatus for drying printed matter printed with ink using an electron beam curing resin. In the figure, 1 is a printing unit, 2 is an electron beam curing device, 9 is a printed material, and 18° and 19 are guide rolls that guide the printed material 9.

The electron beam curing device 2 has the following structure. A box-shaped space is formed by walls 2', and an electron beam irradiation device 3 is attached to the upper part. An entrance/exit portion 8 is opened on one side, and a guide roll 16 is provided on the opposite side. A guide roll 17 is provided at the bottom of the entrance/exit section 8. 4 is an inert gas supply port.

18 and 19 are guide rolls. The printed matter 9 is the entrance/exit part 8
, is reversed by the guide roll 16 and then passes through the guide roll 17
The vehicle exits while being guided by the rollers 18 and 19, and then travels while being guided by the guide rolls 18 and 19.

The present embodiment is configured as described above, and the inside of the electron beam curing device 2 is filled with inert gas supplied from the inert gas supply port 4. This is because the presence of air interferes with the curing of electron beam curing resin. Printed matter 9 printed with ink using electron beam curing resin in printing unit 1
enters the device through the entrance/exit section 8, is turned over by the guide roll 16, and runs through the guide rolls 17, 18, 19.

The printed matter 9 is dried with an electron beam irradiated from the electron beam irradiation device 3. At the entrance/exit section 8, the printed matter 9 coming in and out are approaching each other and traveling in opposite directions, and air 12 is about to enter along with the printed matter 9 on the incoming side, and air 12 is about to flow out along with the printed matter 9 on the outgoing side. The active gases 11 collide with each other to prevent air from entering the device and inert gas from flowing out of the device.

In this way, according to this embodiment, the interference between the air currents accompanying the printed matter can almost prevent air from flowing into the electron beam curing device and the inert gas from flowing out, thereby reducing the amount of inert gas consumed. Operating costs are lower.
