Abstract

PURPOSE:To contrive the shortening of the time required for printing on medicine folding paper and the improvement of the folding efficiency of a medicine folding machine by a method wherein a printer head is provided in the conveying passageway for the medicine folding paper and such paper is printed while being fed to fixed printer head. CONSTITUTION:A printer device 10, when printing data is inputted thereinto, starts the feed of folding paper S at a predetermined rate. At this time, the rate of the paper feed is made lower than that of the printing by a printer head 14. CPU 22 reads out the font data for printing purpose successively from ROM memory 24 according to the inputted printing data. The transfer of the printing position of the folding paper S to the printer head 14 is then detected by the feed amount data from an encoder 25. The CPU 22 activates a solenoid 19 corresponding to the font data through a drive circuit 20 to move a pin 18 so as to hold a ribbon against the folding paper S, thereby effecting the printing in two rows.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method of printing drug packaging paper for packaging drugs such as powdered medicines and tablets.

(Prior art) Heat-fusible packaging paper is transferred in one direction, and during the transfer, the packaging paper is folded in half in the width direction, or the packaging paper that has been folded in half is sent in one direction. A medicine supply chute and a sealing device are installed in the transport path of the packaging paper, and a fixed amount of medicine is intermittently supplied between the folds of the packaging paper from the chute, and the sealing device is used to pack the packaging paper when the packaging paper is transferred. 2. Description of the Related Art Drug packaging devices that continuously form packets each containing a fixed amount of drug by heat-sealing the paper in the width direction and both side edges have been known.

The package taken out from the drug packaging device is usually stored in a medicine bag and handed to the patient, but there are many flrl types of drugs packaged by the drug packaging device, and some are very similar. There is. Furthermore, once the drug is packaged, it is difficult to accurately determine the type of drug from the outside, so when storing the packaged drug in a drug bag, it may be mistaken for another patient's package.

Mistakes like the one above are extremely dangerous, so in recent years,
As shown in FIG. 6, the patient's name, drug name, directions for use, etc. are printed on the package A after the package is packaged.

If the above-mentioned printing is performed after the medicine is packaged, there is a risk that the package will be torn, so the medicine is usually packaged after printing on the packaging paper.

(Problem to be Solved by the Invention) Conventionally, when printing on packaging paper, a blink head is provided in the transport path of the packaging paper, and the printer head is moved in the transport direction of the packaging paper when the packaging paper stops. Since it was printed, printing took a lot of time and there was a disadvantage that the packaging efficiency of the medicine packaging machine was reduced.

Therefore, the technical object of the present invention is to solve the above-mentioned disadvantages, shorten the printing time on sachet paper, and improve the packaging efficiency of a medicine packaging machine.

(Means for Solving the Problems) In order to solve the above-mentioned problems, according to the present invention, a printer head is provided in the transport path of the medicine packaging paper, and the medicine packaging paper is directed to the fixed printer head. The company adopted a configuration in which it prints while transporting the paper.

(Function) With the above configuration, since printing is performed while transporting the drug packaging paper, printing work can be performed efficiently.

[Example] Hereinafter, an example of the present invention will be described based on the accompanying drawings.

As shown in Fig. 1, a roll of heat-fusible packaging paper is placed on the support shaft 1, and the packaging paper S is moved to the transfer path of the packaging paper S pulled out from the roll. Two guide rollers 2 are provided to guide the. This packaging paper S is
The material is transferred at a constant speed in the direction of the arrow in FIG. 1 by rotation of a feed roller (not shown).

A printer device 10 for packaging paper S is provided between the two guide rollers 2.

As shown in FIG. 2, the printer device 10 has a box 11 with an open top, and two guide rollers 12 and a receiving plate 13 are provided on the box 11 between the guide rollers 12. The packaging paper S is guided by two guide rollers 12 and moved along the lower surface of the receiving plate 13.

Inside the box 11, two printer heads 14 are provided below the receiving plate 13. This printer head 14
As shown in FIG. 3, they are provided at a predetermined interval in the transport direction of the packaging paper S, and are shifted in position in the direction transverse to the transport direction of the packaging paper S.

Further, as shown in FIG. 2, an endless ribbon 15 is provided inside the box 11 so as to surround the two printer heads 14, and an upper straight portion 16 of the ribbon 15 is provided.
passes above each printer head 14, and is transported in the direction of the arrow in FIG. 3 by the rotation of the motor 17.

The printer head 14 has a number of pins 18, and the pins 18 are individually moved by solenoids provided within the head 14. Here, the arrangement of the pins 18 is arbitrary, and in the case of the embodiment, as shown in FIG.
A plurality of pins 18 arranged at gI intervals are arranged in double rows.

As shown in FIG. 4, a solenoid 19 that independently moves the pin 18 is connected to each driver circuit 20,
The driver circuit 20 connects the CPU via the output board 21.
22.

The driver circuit 20 may be, for example, a dedicated IC for driving the solenoid 19, a power element such as a transistor or FET, or an IC buffer.
A PI (peripheral interface) etc. latches the data on the data bus at the timing from the CPU 22, drives each corresponding driver 20, and outputs the solenoid 19.
make it work.

The CPU 22 is connected to a RAM memory 23 as a buffer memory for temporarily storing output data, and a ROM memory 24 in which a monitor program for operating the printer device 10 and font data for printing are written. An encoder 25 that detects and outputs feed amount data is connected.

The encoder 25 is, for example, an optical or magnetic rotary encoder installed between the two printer heads 14 as shown in FIG. For example, when the packaging paper S (including heat-sealing material) for the packaged bone moves over the printer head 14 in the transport direction, the detection roller 26 rotates once, and the feed amount data is detected without mistakes.

Further, as shown in FIG. 4, the CPU 22 includes, for example,
An external terminal 29 such as a personal computer is connected to an I10 boat 28 such as USART or Plo that transfers data, and data is transferred in parallel to the external terminal 29 via control signal C such as BIJSY or 5TROBE. (Sen I Ronix).

This embodiment is configured as described above, and when the printer device 10 starts processing and sets the roll of sachet paper on the support shaft 1, the printer device 10 waits for data and human input. At this time, when print data is input to the external terminal 29, the external terminal 29 transfers the print data to the printer device 1o.

When the printing data is input, the printer device 10 starts transporting the packaged paper S at a constant speed (the transport speed at this time is slower than the printing speed of the printer head 14), for example, The CPU 22 sequentially reads out the font data for printing from the ROM memory 4 according to the manually inputted printing data, and the printing position of the sachet paper S is moved to the printer head 14 according to the feed amount data from the encoder 25. When the CPU 22 detects the font data, the drive circuit 20 drives the solenoid 19 corresponding to the font data, moves the pin 18, and moves the ribbon 15.
is pressed against the packaging paper S, for example, as shown in FIG.
Prints two columns.

In this way, in this printer device 10, the printer head 14 is fixed and printing is performed by moving the packet paper S.
There is no loss time associated with starting and stopping the packaging paper S and moving the printer head 14 as in the conventional method, and the time required for printing is shortened. Particularly, when printing is performed continuously on the packets S, the loss time is accumulated, so that a significant time reduction can be achieved.

〔effect〕

Since the present invention is configured as described above, it is possible to solve the problems of conventional drug packaging machines, such as the dead time caused by stopping and starting the packaging paper and moving the printer head. Packing efficiency can be improved.

Furthermore, since there is no mechanism for moving the printer head, the system becomes simple, which reduces the number of failures and simplifies maintenance.
