Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printer device in a label printing and pasting machine, which includes a plurality of printers and allows each printer to print in a different color.

When printing letters and numbers on labels by type (date, price, etc.) using multiple printers, each printer uses a different color of ink and roller. The type represented by each character can be clearly seen at a glance, and the label can be made aesthetically pleasing.

The present invention is a multicolor label printing and pasting machine for printing such labels, and the conventional ink roller device for this type of label printing and pasting machine is a unique ink roller whose width is just the width of the marking on the printer. are mounted in parallel on one shaft, the ink roller is placed at one end of each printing device, and during the printing process of the printing device, the ink roller is rubbed in the longitudinal direction of each printing device and moved to the other end, Each printer is equipped with an ink roller device of a different color, and if there are two printers, an ink roller device of a different color is installed at the front and rear of each printer. There is a method in which the printer is moved to both sides of the printer.

However, since the former method is attached to a single shaft with different colored ink rollers, special means are required to prevent the ink from each ink roller from seeping into other ink rollers, and the ink roller is also used for printing. The structure of the means for longitudinally transitioning from one end of the vessel is very complex and is therefore prone to failures.

Furthermore, in the latter type, ink roller devices are installed on both the front and rear sides of the printer, so the pasting machine becomes large and is limited to two printers.

In the present invention, each of the plurality of printing devices is provided with a respective ink roller that applies ink by an ink roller having a shaft parallel to the arrangement of printing impressions of the printing device, and each of the ink rollers is provided with an ink roller that applies ink to the printing device. During the printing process, the ink rollers are connected together and moved to the side of the printing device, at which time ink is applied to the markings of the printing type, but each ink roller is careful not to come into contact with any printing markings other than its corresponding printing marking. This solves the problems of the conventional multi-color printer device.

The present invention includes a guide plate that holds a plurality of printing devices and forms a stepped guide edge surface whose lower surface serves as a transition guide for the ink roller, and an ink roller that corresponds to the lower printing stamp of each of the printing devices. , the side plates of each of the ink rollers are two-shaped side plates consisting of an inner disk with a large diameter and an outer disk with a slightly smaller diameter, and the rotation axis of each of the ink rollers is an ink roller holding plate. The ink is rotatably connected.
The roller holding plate is rotatably connected at its center to the lower end of a swinging arm that is pivoted to the side plate of the label printing and pasting machine main body, and the swinging arm is attached so as to press the ink roller against the bottom end of the printer. When the handle of the label printing and pasting machine is grasped and the ink roller is pushed down by the printing devices, the outer disk of the ink roller side plate engages the lower edge of the stepped guide plate on the outer surface of the printing device.
