Abstract

PROBLEM TO BE SOLVED: To eject uniform high pressure air to a printing face of a package to completely remove attaching water drops by fixing an air hose to an upper part of an air chamber and forming a nozzle with a longer rim piece and a shorter rim piece facing in parallel at a lower end. SOLUTION: An elongated air chamber 3a is formed in parallel with a transfer direction of a package transfer conveyer 15, and an air hose 10 extending via a blower 5 and a heater box 6 is fixed to an upper part. In addition a nozzle is formed with a longer rim piece 3b and a shorter rim piece 3c facing in parallel at a lower end of the air chamber 3a. Air is introduced from the air hose 10 into the air chamber 3a and pressurized, thereby ejecting high pressure air uniformly from the nozzle. Since the air is ejected from the longer rim piece toward the shorter rim piece of the nozzle at this time, it is possible to control an ejecting direction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for printing expiration dates and symbols on a package to which frozen or water droplets have adhered by means of an ink jet printer. The present invention relates to an IJP marking device with a water droplet removing function capable of performing a printed pattern.

[0002]

2. Description of the Related Art Conventionally, when a shelf life or a sign is imprinted on a package such as a retort pouch to which frozen or water droplets are attached, if the product is mass-produced or mass-consumed, the contents are packaged. Before the printing, printing is performed in advance on a sheet-like package by an ink jet printer (hereinafter, referred to as IJP), and then the contents are filled and packaged.

In the case of small-volume production, printing is performed by IJP each time the product is shipped. However, since the printing surface of a package such as a retort pouch is in a frozen or water-dropped state, it cannot be printed directly by IJP. For this reason, high-pressure high-temperature or room-temperature air is jetted onto the printing surface of the package such as the retort pouch, and printing is performed after removing or drying water droplets generated from dissolution or water droplets originally attached. .

As means for injecting high-temperature air, air blown from a blower is heated at a high temperature in a heater box and connected to a pipe via an air hose.
As means for injecting room-temperature air, air blown from a blower is directly connected to a pipe via an air hose. A nozzle having a thinned tip is fixed to the pipe body at an appropriate interval, or a hole is directly formed as an air blowing hole, and the nozzle is jetted onto a printing surface of the package transported by the package transport conveyor.

[0005]

However, in the method for removing or drying water droplets as described above, high-temperature or normal-temperature air jetted from a nozzle or an air blowing hole is uniformly applied to a printing surface of a package such as a retort pouch. High-temperature or room-temperature air opened to the atmosphere from a nozzle or an air outlet hole caused a decrease in wind pressure, and it was not possible to reliably remove or dry water droplets. For this reason, there is a problem that a printing failure occurs.

In addition, when the high-temperature air is jetted, there is another problem that when the contents are raw, in particular, raw fish, the contents are easily discolored and deteriorated. For this reason, in order to surely remove or dry the water droplets, there is a case where a manual operation of manually wiping a printing surface with a cloth is performed, and there is a problem that the operation efficiency is reduced.

[0007] The present invention has been made in view of the above problems, and in removing or drying water droplets, high-temperature or normal-temperature air blown through a blower and a heater box is used for freezing or water droplets of a retort pouch or the like. Water droplets that can be sprayed evenly and without a decrease in wind pressure on the printing surface of the package with the attached water droplets, reliably remove or dry the water droplets attached to the printed surface evenly, and perform stable printing. An object of the present invention is to provide an IJP stamping device with a removing function.

[0008]

In order to solve the above-mentioned problems, in the IJP stamping device 1 with a water droplet removing function of the present invention,
An elongated air chamber 3a is provided in parallel with the transport direction of the package transport conveyor 15. An air hose 10 extending through a blower 5 and a heater box 6 is fixed to an upper portion of the air chamber 3a, and a long edge piece 3b and a short edge piece 3c face the lower end of the air chamber 3a in parallel to form a nozzle. A uniform high-pressure air is jetted onto the printing surface of the package 20 by the water droplet removing nozzle 3 formed as described above.

A package holding conveyor 16 is provided between the water droplet removing nozzle 3 and the package conveyor 15. The package holding conveyor 16 is operated at a speed synchronized with the package conveying conveyor 15, and a plurality of pressing rollers 21 arranged at appropriate intervals in a belt 25 of the package holding conveyor 16 are built in, and The package 20 is conveyed in a stable state by absorbing the irregularities of the package.
