Abstract

PURPOSE:To lower the cost of running by a system wherein the state of the movement of a label is detected and hammers different in dot patterns are operated in accordance with the movement to form characters as if a printer were moved. CONSTITUTION:Labels 2 are stuck on ground paper 1 and rolled up in a roll 5. When an article 6 to be labeled passes under one of the labels 2, a driving motor 11 for the labels is driven in accordance with the speed of movement of the article, based on a detection signal of a detector 7, and is stopped by a detector 8 detecting the movement of one label. This state of movement is detected by an encoder, and a signal thereof is delivered to a controller. The controller conducts an arithmetic operation on signals of a set character pattern and the speed of movement of the label and instructs each dot hammer to conduct operation or no operation for stamping. The label is moved and further another dot hammer instructed conducts stamping to form a character, a sentence, a date, etc. Accordingly, the object can be attained by using ordinary paper for labels without using such expensive paper as heat-sensitive paper.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for printing dates, prices, etc. on labels using a continuous label pasting device in which labels are pasted onto a mount and wound into a roll.

(Prior Art) Conventionally, when printing on a label or the like, printing was performed on the top surface of the label using a rubber stamp or printed letters via an ink ribbon in synchronization with the intermittent movement of the label. In the case of such rubber stamps or printed letters,
It was a hassle to have to set it every time the date changed. To eliminate this inconvenience, a printing device using a hot printer uses thermal paper for the label itself and changes the character formation by changing electrical signals, but thermal paper is expensive and the label itself The drawback was that running costs were high.

In addition, when printing with a dot printer, the printer itself is moved to print, so it was thought that printing on a label using a labeling device could not be used due to the speed required.

(Problems to be Solved by the Invention) It is well known that dot printers print at high speed, and the present invention can be applied to printing on labels, etc. by forming characters without moving the printer itself. The objective is to obtain the movement speed of this label and the timing of the printer's hammer operation.

(Means for Solving the Invention) The present invention is configured as follows as a means for solving the above problems.

A means for moving the backing sheet on which the label is pasted, a means for instructing to start printing, a means for setting the character pattern on the dot printer, a controller for instructing each dot hammer to operate, and this controller detecting the movement status of the label. It has a means for sending a symbol and a means for preventing the label from meandering, detects the moving state of the label and transmits it to the controller, and operates a dot hammer of a predetermined character in accordance with this speed, Activates hammers with different dot patterns in response to the movement of the label,
As a result, characters are formed as if by moving the printer. When the printer is moving, there is no risk of the characters being misaligned due to the back and forth movement of the shaft, etc. However, as the label is moved, it is necessary to minimize the shaking during movement, so pinch rollers are used.
While running the label, guides on both sides control left and right wobbling.

(Example) An embodiment of the device of the present invention will be described with reference to the drawings.

In FIG. 2, a label 2 is pasted on a mount 1, wound in a roll 5, and set. When the object to be pasted 6 passes under the label, a detection signal from the detector 7 drives the label drive motor 11 in accordance with the moving speed of the object to be pasted. This drive motor 11 is stopped by a detector 8 which detects movement of a portion of the label. Pinch roller for running the label by driving the drive motor 11
21°22 The label moves due to insufficient drive. This moving state is detected by an encoder 12 attached to either of the pinch rollers 21 or 22, and the signal is sent to the controller 30. The controller 30 calculates the signal of the set character pattern and the moving speed of the label, and instructs each dot hammer to operate or deactivate. The designated dot hammer makes a stamp, the label moves, and the designated dot hammer makes a stamp, forming one set character, text date, etc. Label movement speed is usually 17-2
0 import/min. The moving speed of the dot printer is 0.4
m/sec to 1.4 m/sec. Therefore, even when the printer is not moving, the moving speed of the label is approximately 0.3 m/sec, so there is enough time for it to be formed as a character.

Next, explain the operation of the printer using a flowchart diagram.Separate the characters such as 0 date and set the dot pattern (
After step 1), check to see if the label is moving.If it is not moving, wait until it moves.If it is moving, check the marking speed of the dot hammer based on the signal from the label movement/speed detection. Calculate (relative to pitch) (step 3), check whether the print start trigger is activated or not (step 4), if the trigger is activated, operate the dot hammer for the first pattern and engrave (step 5) 0th order Step 6) Determine whether the label has moved further by one pitch. If it has moved, operate the dot hammer for the next pattern and mark it (Step 7). Determine whether the label has moved by the set number of pitches. Step 8) If the dot has been moved by the set number of pitches, check whether the set pattern of dots has been stamped by the dot hammer in accordance with each movement pitch.Step 9) If the dot has been stamped, stop the operation of the dot hammer. (Step 10), Step 5, Step 6, and Step 7 in each judgment or check, if there is no input or movement, etc., each waits in that state.

The operation of the device will be explained according to the above flowchart. In Figure 1, a mount 1 is attached with labels 2 in a row, and a roll of 5
is set in the pasting device.

The label 2 is slightly peeled off from the mount 1 so that it adheres to the object 6 when it passes therethrough. A folding point 24 of the mount 1 is provided for peeling off the label 2 from the blank paper 1. For this reason, a portion of the label is placed on standby with the plate slightly protruding from the folding point 24. There is a detector 7 which detects when the object to be pasted passes under it, and at the same time when the label 2 touches the object to be pasted 6 by one inch, a detection signal is sent to the label drive motor 11, and the pinch roller 21, 22
Rotate to move the label. The drive motor is stopped by a signal from the detector 8 which detects that the label has moved by -. When one label moves in this manner, in the case of the numbers shown in FIG. 5, the dots are separated according to the matrix shown in the figure. The vertical number is the hammer number, and the horizontal number is the number of moving pitches. When the printing start trigger (in this embodiment, the signal from the passage detector 7) is input, the dot hammers 32, 36, and 37 make the first marking, and the second marking is at 31° as the label runs. 35.37
No. 31, 34. 37, 4th 31.33.3
No. 7, 5th 32, 33, 37 hammers are engraved,
The number shown in the figure is formed, and after a blank pitch, a pattern is set to form the next number or letter. Each dot hammer makes a stamp as the label moves, and the set number of pitches and dot hammers of the set pattern are stamped. When all is completed, printing of one label is finished, and the next printing start trigger is waited.

Although the embodiment of the device of the present invention has been described above, another embodiment is as follows: 1. Printing multiple lines of characters by connecting multiple dot printers. 2. After printing the first line, turn the printer on. The scope of the present invention is to move the dot printer and then print on the second column. By being able to form numbers or letters only by marking with a dot hammer while the paper is moving, it is possible to achieve the desired purpose with ordinary paper without using expensive paper such as thermal paper. Compared to other technologies, running costs have been greatly reduced.
