Description

[Detailed Description of the Invention] The present invention relates to a price tag printing machine that prints desired information on a strip of paper and cuts it to continuously produce a required number of price tags. Generally, for price tags such as retail business tags used for POS systems, a strip of paper is continuously transported, and information from an information processing device into which print data and the number of sheets to be printed are input in advance is printed on the paper. It is cut and processed to obtain a single leaf (equivalent to one price tag). 1st
The figure is a side view showing a schematic configuration of a price tag printing machine according to the present invention using a non-impact recording method, and an electrostatic recording method price tag printing machine is illustrated as an example. Reference numeral 1 denotes a strip of paper wound around a reel 2, which is moved around guide rollers 4 and 5 by a transfer device 3 rotated by a drive motor.
It is continuously delivered to the delivery roller 6 through the. Reference numeral 7 denotes a curl removal device for removing winding distortion of the paper strip 1, and 8 forms an electrostatic latent image of a predetermined character pattern on the paper strip 1 based on electrical signals from an information processing device (not shown). electrostatic recording head for, 9
10 is a toner application device for developing the area where the electrostatic latent image is formed to make it visible, and 10 is a fixing device for heating the applied toner with a heater 11 to fuse and solidify the displayed character pattern. . 12
are a pair of support members, and the support members 12 include a platen 13 in the shape of a roller for pressing the paper strip 1 against the recording head 8 during operation, and a guide roller for pressing the paper strip 1 against the toner application device 9. 14 is supported. 15 is a cutting device for cutting the strip price tag at predetermined intervals perpendicular to the running direction, and includes a fixed blade 16 and a rotating blade 1 that constantly rotates.
It consists of 7. The required number of value holes 18 cut to the length of one sheet are guided by the delivery roller 6 and stored in the stacker 19, and the unnecessary bills 20 are sorted by the selection device 21 and placed in the unnecessary bill storage box 22. guided by. When the printing press is not in operation, the support member 12 has a platen 13 and a guide roller 14 located away from the recording head 8 and the toner application device 9, respectively, and when the printing press is in operation, the platen 13 and the guide roller 14 hold the strip of paper. 1 is brought into pressure contact with the recording head 8 and the toner applicator 9, respectively. Conventionally, this contacting and separating operation was performed manually or by installing other special mechanisms, resulting in poor work efficiency and high costs. was. This proposal is an improvement on this point, and its specific structure is shown in FIGS. 2 and 3. The paper strip 1 fed from the reel 2 by the transfer device 3 is transferred to the guide roller 4, the roller 23 of the curl removal device 7, and the guide roller 5 of the platen.
It then passes below the recording head 8 and toner application device 9. At the same time as the printing press is started, the curl removal roller 23 is moved around its support shaft 25 by a torque motor (not shown) provided in the main body 24.
Direction for removing winding distortion of paper strip 1 (direction of arrow)
Rotate to. That is, the curl removal device 7 applies tension to the paper strip 1 in the opposite direction to the direction in which it is wound around the winding frame 2,
Correcting the so-called curly curls. One side support member
A side edge of the support member 12 is provided with a support member 12 for displacing the support member 12 in the direction in which the platen 13 presses the strip-shaped paper 1 against the recording head 8 and comes into contact with the curl removing roller 23 as the curl removing roller 23 rotates. A convex piece 26 is formed. That is, when the curl removal roller 23 rotates in the direction of the arrow and pushes the convex piece 26, the supporting member 12 is lifted up from the solid line to the position shown by the dotted line in FIG. The mechanism is such that it is brought into pressure contact with the electrostatic recording head 8. According to the present invention having the above configuration, the strip paper 1
At the same time that the curl removal device 7 operates to remove the winding distortion, the support member 12 is pushed up and the strip paper 1 is pressed against the electrostatic recording head 8 by the platen 13. Therefore, compared to conventional equipment, it has the advantage of being able to perform work extremely efficiently.
