BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eye mark printing and perforation processing apparatus for thermal printer paper, in which eye mark printing and perforation processing on thermal printer paper are performed using the same common cylinder.
[0002]
[Prior art]
Recently, handy terminals using thermal printers have been used for meter reading of gas, water, and power meters. This handy terminal reads the usage amount of gas, water, electric power, etc., prints the result on the spot as a notice sheet, separates the printed result and passes it to the user.
The printing paper used in such a handy terminal is a continuous roll paper or folding paper, and is a sewing machine for accurately printing within a frame of a predetermined format and separating it into a single printing format. Eyes are put in. In order to determine the position of the format, an eye mark corresponding to each format is printed in advance, and this mark is detected by a sensor of the thermal printer, and positioning for printing is performed.
Recently, data such as printed characters and numbers is often read by an automatic character reader (OCR), and the accuracy of the positions of characters and numbers printed from the front end of the perforation cut position is strictly required. It has become like this.
[0003]
For example, in the standard of postal transfer privately made standard for creating postal transfer dedicated payment form, the payment form consists of a transfer handling slip consisting of an account number column, an amount column, a subscriber name column, and a transfer slip consisting of a transfer slip and receipt. The perforation is inserted between the transfer handling slip and the transfer slip, and the positional relationship is strictly defined.
That is, as shown in FIG. 3A, the left perforation of the transfer handling slip should be within 4 mm ± 0.3 mm from the left vertical line in the account number column. Similarly, the position of the printing slip alignment frame of the transfer slip is strictly determined based on the left hand of the transfer handling slip.
In order to comply with these strict standards, it is necessary to use a thermal printer with high print positioning accuracy. However, the accuracy of the postal transfer payment slip printed by the thermal printer is the same as that of thermal printer paper. The accuracy of the positional relationship between the perforation and the eye mark set in advance is greatly affected. For this purpose, as shown in FIG. 3A, in order to print the left vertical line in the account number column within 4 mm ± 0.3 mm from the left perforation of the transfer handling slip, the perforation and the eye mark As shown in FIG. 3B, it is necessary to maintain the accuracy of the positional relationship between and 20 mm ± 0.05 mm or less.
[0004]
[Problems to be solved by the invention]
However, in the conventional eye mark printer, it is impossible to always keep the processing accuracy between the perforation and the eye mark printing within 20 mm (this value is an example) ± 0.05 mm or less. The reason is that, in the current rotary printing press, the distance between the printing unit and the perforation unit is at least 1 m, so the positional dimension (phase) between the perforation and the eye mark has a tolerance of ± 0. This is because 2 mm is the limit.
Further, during the printing process, a positional deviation between the perforation and the eye mark occurs due to a change in the tension of the paper roll, and it is necessary to always adjust this. If high accuracy is required for the positional relationship between the perforation and the eye mark, the yield of the product will deteriorate, so it is difficult for current thermal printer paper printers and sewing machines to meet the standards of the postal transfer private standards. It was.
[0005]
[Means for Solving the Problems]
The present invention relates to a printing plate cylinder of a rotary printing machine that prints an eye mark on continuous roll paper or folding paper used in a handy terminal, and a sewing unit that puts perforations on continuous roll paper or folding paper. By realizing an eye mark printing and perforation processing device for thermal printer paper comprising a sewing machine cylinder, a printing cylinder of a rotary printing press, and a common cylinder commonly used for the receiving cylinder of the sewing machine unit The positional dimension (phase) between the perforation and the eye mark is reduced in tolerance so that high-precision thermal printer paper can be easily produced.

DETAILED DESCRIPTION OF THE INVENTION
【Example】
FIG. 1 is an explanatory diagram showing the configuration of an eye mark printing and perforation processing apparatus for thermal printer paper according to the present invention. In FIG. 1, reference numeral 10 denotes a printing plate cylinder of a printing unit of a rotary printing machine that prints eye marks on continuous roll paper or folding paper. Reference numerals 11, 12, 13 and 14 denote ink rollers of a printing unit for supplying ink to the printing plate cylinder 10. Reference numeral 20 denotes a sewing drum of a perforating unit for perforating continuous roll paper or folding paper. A common cylinder 30 is used in common for the printing impression cylinder and the receiving cylinder of the sewing machine processing unit. Reference numeral 40 denotes a fixed roller (commonly known as a nip) for bringing the paper into close contact with the common cylinder. 51 and 52 are guide rollers for guiding the paper to the common cylinder. Reference numeral 60 denotes a continuous roll paper or folding paper on which the eye mark and perforation are processed.
[0007]
The continuous roll paper or the folding paper 60 is introduced into the common cylinder 30 via the guide roller 51, and the perforation is first processed by the sewing machine cylinder 20. Next, the eye mark is printed on the common cylinder 30 by the printing plate cylinder 10 of the printing unit. In this case, the continuous roll paper or the folding paper 60 is always pressed and brought into close contact with the common cylinder by the fixed roller 40. A continuous roll paper or folding paper 60 on which perforation processing and eye mark printing have been performed is sent out to the outside via a guide roller 52. As a printing method for printing the eye mark of the printing unit, any of letterpress (including flexo), gravure (intaglio), and offset (flat plate) can be used. In the above description, an example in which the perforation is first processed by the sewing cylinder 20 on the common cylinder 30 and then the eye mark is printed by the printing plate cylinder 10 of the printing unit will be described. However, the operation performed on the common cylinder 30 may be such that the perforation is processed after the eye mark is printed first.
[0008]
In the eye mark printing and perforation processing apparatus of the thermal printer paper having such a configuration, the perforation cylinder 20 that performs perforation processing and the printing plate cylinder 10 that performs eye mark printing are disposed at extremely close positions. The positional relationship is always kept mechanically constant.
Further, since the continuous roll paper or the folding paper 60 is always pressed and brought into close contact with the common cylinder 30 by the fixed roller (nip) 40, the machine cylinder 20 that performs perforation processing once it is aligned and operated. And the printing plate cylinder 10 on which the eye mark is printed, there is no change in tension that causes an error in the middle, so that the perforation and the eye mark are caused by the change in the tension applied to the paper 60. There is no deviation in the positional relationship between As a proof that there is no variation in the accuracy of the product, even when a thin eye mark was printed at the center of the perforation, printing without deviation was always possible.

It is. In FIG. 2, the same parts as those in FIG. In FIG. 2, reference numeral 20 denotes a perforation unit of a perforating unit for perforating continuous roll paper or folding paper. A common cylinder 30 is used in common for the printing impression cylinder and the receiving cylinder of the sewing machine processing unit. Reference numeral 40 denotes a fixed roller for bringing the paper into close contact with the common cylinder. Reference numeral 60 denotes a continuous roll paper or folding paper on which the eye mark and perforation are processed. Reference numerals 21 and 22 denote bearers provided at both ends of the sewing machine cylinder 20. The bearers 21 and 22 lift the sewing machine cylinder 20 from the common cylinder 30 by a predetermined distance. Reference numeral 25 denotes a perforating tooth planted in the sewing body 20. Reference numerals 23 and 24 denote backup rolls.
[0010]
The continuous roll paper or folding paper 60 is introduced into the common cylinder 30 via a guide roller (not shown), and the perforation is processed by the sewing machine cylinder 20.
The sewing machine drum 20 is lifted from the common drum 30 by the bearers 21 and 22 by a certain distance, and the teeth 25 for perforation are planted at the same level as the contact surface of the bearers 21 and 22 with the common drum 30. The bearers 21 and 22 are pressed against the common cylinder 30 by the backup rolls 23 and 24 with a constant pressing force. For this reason, the impact given to the common cylinder 30 at the time of perforation processing can be eliminated.
1 and 2, the positional relationship between the eye marks printed on the thermal printer paper and the continuous roll paper processed by the perforation processing apparatus or the perforation of the folding paper 60 and the eye mark is always an accurate value. Therefore, the positional relationship accuracy can be kept within a tolerance of ± 0.05, so that the domestic products with variations can be easily manufactured.
