Abstract

PURPOSE:To regenerate an ink ribbon with high speeds and a high energy efficiency by a method in which a conductive heat-meltable solid ink is melted by applying a voltage to a melting roller having paired electrodes on its surface and supplied to the ink ribbon. CONSTITUTION:When applying a voltage between the electrodes 7a and 7b in an ink melting roller 7 in which two electrodes 7a and 7b each having large numbers of rectangular teeth-shaped projections 7a' and 7b' on its periphery are set and fixed at intervals, current is flowed in the contact surface part of the conductive solid ink 9 to melt the ink 9 by Joule heat, and the molten ink 9 is adhered to the surface of the ink-melting roller 7 and supplied to the surface of the ink ribbon 2 as the roller 7 turns. The roller 7 may be used as an electrode and the guide plate for the solid ink 9 may be used as the counter electrode.

Description

[Detailed description of the invention] This chest is made of LK4 ink heat-distributed brass iron.
It is used for Fyo regeneration.

Conventional methods for regenerating ink ribbons for printers and printing images include a method of using a heated roller to supply ink to the ink ribbon, and a method of melting the ink beforehand. , When using a heated roller, there are the following disadvantages: 1) The O energy is large because the ink is melted; 2) The thermal response of the roller is poor (ink supply amount control characteristics are poor)
Since the amount of ink applied to the ink ribbon (ink support) cannot be determined, it is not possible to supply the ink to the koji.Furthermore, in the method of preparing the ink ribbon in advance, (1) an unpleasant odor is generated due to the generation of dregs, etc.; ■ Since all the ink is melted, there is a large energy loss.■ The first disadvantage is that the waiting time after turning on the power is long.

The present invention eliminates these drawbacks, allows the transfer ink ribbon to be reused, and reduces running costs.

Below are seven theories based on the drawing #IC.

FIG. 1 is a schematic diagram of the implementation of the ink ribbon regenerating apparatus according to the present invention, and FIG. 2 shows the steps for regenerating the ink ribbon.゛In Fig. 1, there is a print head 4 which moves from side to side, being held between the ink print head 2 and the platen 3 on the thick paper l.
′□ is a trap so that printing (or printing) is performed. Further, the ink ribbon 2 is passed between guide rollers 5 and 6, is brought into pressure contact with an ink melting roller by a pressure contact roller 8, and is further projected onto the print head 4 and onto the platen 3! The IC is hung and the guide rollers 5 and 6
One clockwise rotation of the arrow causes the arrow to immediately move in the direction of the arrow.

On the other hand, on the opposite side of the ink roller 1lII which is in contact with the ink ribbon 2, a conductive heat-melting ink 9 is brought into pressure contact with the nubbling 10, and the fkIim ink ribbon 9 is brought into contact with the ink roller 7 by the ink melting roller 7. It is configured so that an ink ribbon 2 is attached.

By the way, what about print head 4? i: When printing is done on IJ printing paper l, the ink on the ink ribbon 2 is #41
Due to the pattern of I''j, there is a partial loss of I & casing or the amount of ink is reduced. In addition, a remaining ink amount detection roller 2' is provided to detect the remaining amount of ink in No. 7, and the ink supply operation using the ink melting roller flow is performed according to the detection number.
A second ink averaging roller 13 is also provided for uniformizing the ink on the ink ribbon when the ink is supplied by the ink melting roller 7. This first
The process of regenerating the ink ribbon in the illustrated embodiment of the present invention is carried out as shown in the 70-chart of the KM regeneration system in FIG. That is, print head 4
The remaining ink on the ink ribbon, which is no longer uniform due to the H=o-shape, is removed by the ink averaging cooler 11.
After leveling, check the remaining amount of ink [Ink 1l II Melting Roller I
If necessary, the ink from the solid ink 9 being used is supplied onto the ribbon 2 by the melting roller 7, and 1 mg of ink on the ink ribbon 2 is again fed by the ink averaging roller 13. It has been adjusted to one level, and the printed part is set to have a red 9 and a 1. It is easy to detect that Konin averages the ink before performing the ink level check 5fJk.
This is to make it 1 (the detected basket becomes cheap 5i!)
However, if it is not necessary to perform such detailed control, the ink averaging roller 11 may be omitted.

Place a warm pressure mark with the same potential as 4 solid ink 9 on the surface of the ink ribbon.
K may also be used to transfer the image onto the image. In this case, the ink is uniformly transferred to rC and transferred to the uneven VC of the roller, or smoothed by the second equalizing roller 13 to form a ribbon of uniform ink warm cloth.

The ink averaging rollers 11 and 13 are conventional ink averaging rollers 7 and 1M1 shown in FIG.
#1lI is emitted by applying an electric current to the conductive ink above.
I! The ink is melted to average the ink on the ribbon 2, and details of the seventh part 1I111 are shown in FIGS. 8 and 9. Also, as shown in Fig. 46, the ink averaging roller 11 that touches the ink supporting surface of the ink ribbon 2 supported by the guide roller 8 is connected to the ink f#1IIc+-rough and two electric currents on the same machine. The electrode 11a of 211i1 is formed into an oval shape so as to face each other in the circular direction, and as shown in 1Iv-, the electrode 11a of 211i1.

Nobuhito's rollers are connected to the 11bk shaft so that they interlock with each other. The ink averaging roller 11 is formed by assembling two poles of the same shape and is formed into a desired shape using an insulating material. It is best to add an rc taper so that the center part is □ concave so that it can be gathered in the housing. In this way, the ribbon is softened or the ink melts into the ribbon.
'c gathers and does not protrude from the ribbon. The idea of attaching a taper so that the center S is concave can also be applied to the ink melting roller 7. This ink average roller 1
When a voltage is applied between the electrodes 11a and llb of 1, the conductive ink layer on the ink ribbon 2 [valves and current flows].
Due to the heat generation action, the inters are melted, and the ink averaging roller l14DI1m (i [1) which is press-fitted causes the ink on the ink ribbon 2 to be averaged. Note that the ink averaging roller may be a heated roller, but A current-flow melting system like the one in the first generation is more efficient, and also has a better start-up V after the idle Haseyu 9 and IE-insertion.

The remaining ink amount detection roller 12 is as shown in Fig. 1O.
The amount of residual ink on the ink ribbon 2 [brush 12a', 12b'] is spread on the edge of the conductive ring 12a, 12bkm surface and is averaged by the ink averaging roller 11.
It is detected by measuring the electrical resistance V through the roller, and the roller itself is made of insulating material. During unloading, the ink ribbon 2 supported and guided by the pressing roller 914 is brought into contact with the remaining ink weight detection roller 12't*, and the conductive links 12m, 12

know Next, the operation of the apparatus according to the present invention shown in FIG. 1 will be explained. When the printing head 4 prints on the rigid paper l, the ink on the ink ribbon 2 is partially missing due to the printing pattern and is not uniform, so the ink averaging roller IIK The remaining ink on the ink ribbon 2 is made uniform, and the ink m on the ink ribbon 2 is made uniform by the ink remaining snow detection roller 12.

The ink on the ink ribbon 2 is smoothed by the second ink averaging roller 13 for smoothing the ink on the ink ribbon 2 into a shape of 1111[4 t. As in the case of the ink averaging roller 110, it is not necessary to provide a taper such that the middle body is concave.

In the present invention, conductive taLk heat-melting solid ink 9t is used, and a pair of electrodes [arranged ink melting rollers 7] are provided on the surface.
By applying appropriate voltage when necessary, the ink surface that is in pressure contact with the ink in a solid state is heated by t joules, which costs $1611 (
The ink attached to the collecting surface of the roller 7 is transferred onto the ink ribbon 2 by the rotation of the roller, so the energy key effect when regenerating the ink ribbon is good, and the solid ink for High-speed ribbon melting can be done with ilIIIiM! ＋Can be lost, and ink il1
