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, in a medicine folding device having a printer device, a drug chute and a sealing device in the passageway for medicine folding paper, raw data is printed during the period of skipping the folding paper sections at the time of the new data input. CONSTITUTION:When printing data such as the name of a patient is changed, a printer device skips a few of the folding paper sections not requiring printing of medicine folding paper being fed. During this time, the CPU 22 of the printer device asks an external terminal 29 to send new printing data so as to perform, during the paper skipping 82, the processing 83 of the printing data, whereby the font data for printing purpose is read out from ROM memory 24 according to the inputted new printing data and set in an output port 21 in readiness for the next printing. Immediately after the paper skipping 82 is complete, the printing 84 of the new data on the medicine folding paper is started. For this reason, if execution time is the same, print processing time is shortened by (t) per data renewal.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for printing medicine packaging paper for packaging medicines 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 a sealing device is used when transporting the packaging paper. 2. Description of the Related Art Medicine packaging devices that continuously form sachets containing a fixed amount of medicine by heat-sealing the width direction and both side edges of sachet paper are conventionally known.

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

Mistakes like the one above are extremely dangerous, so in recent years,
As shown in FIG. 6, the sachet A is provided with printing B containing the patient's name, drug name, directions for use, and the like.

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

[Problem to be solved by the invention]

However, when printing on sachet paper, conventionally, when print data such as a patient's name is updated, the printer device 10, as shown in FIG. In order to prevent residual medicine from getting mixed up in the chute and to distinguish between packets A, after empty feeding 82 of several batches of packaging paper is performed, updated data is printed 84. However, in order for the printer device 10 to print, a printing process 83 that processes human data is required, and printing 84 cannot be performed immediately after the completion of the blank feed 82, and the printing process 83 waits for a processing time t. state. Therefore, when data is frequently updated, the waiting time that is repeated each time the data is updated results in a large time loss, which is disadvantageous in that the packaging efficiency of the medicine packaging machine is reduced.

Therefore, this invention solves the above-mentioned disadvantages, shortens the printing time on packaging paper, and improves the packaging efficiency of the drug packaging device. The topic is

[Means for Solving the Problems] In order to solve the above-mentioned problems, according to the present invention, there is provided a drug packaging device in which a printer device, a drug chute, and a sealing device are provided in a transport path for drug packaging paper. Therefore, a configuration was adopted in which the update data is printed during the empty feeding period of the packaging paper when the update data is input.

The above-mentioned idle feeding period is used to distinguish between leftover medicine from the medicine chute and the packaging paper when the printer updates data, that is, when the data printed on the packaging paper is changed.
This is a period in which the paper is sent in several packets without printing, and is determined as appropriate based on experience and experimentation.

[Effect]

With the above configuration, printing processing is performed during the empty feeding period of the packaging paper, and printing is performed immediately after the empty feeding ends.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, a roll of heat-fusible packaging paper is set on the support shaft 1, and the packaging paper S is moved along the transport 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. 5, a plurality of pins 18 arranged in a straight line at equal intervals are arranged in double rows.

As shown in FIG. 4, a solenoid IS that independently moves its pin 18 is connected to each driver circuit 20,
The driver circuit 20 connects to 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 a FET, or an IC buffer.

The output boat 21 has a data latch function, for example,
The data on the data bus is latched at the timing from the CPU 22 using a flip-flop, PPI (Peripheral Interface), etc., and each corresponding driver 20@X
Move rA to activate solenoid 19.

The CPU 22 is connected to a RAM memory 23 as a batza 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, and a ROM memory 24 for feeding the sachet paper S. An encoder 25 that detects and outputs quantitative 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 of the packaging needle (including heat sealing) moves over the printer head 14 in the transport direction', the detection roller 26 rotates once, and feed amount data can be detected without interruption.

In addition, as shown in FIG. 4, the CPU 22 includes, for example,
An external terminal 2S such as a personal computer and an I10 boat 28 such as USART and Plo that transfer data are connected to BtJSY.

Parallel transfer (centronics) or serial transfer of data with the external terminal 29 is performed via a control signal C such as 5TROBE.

On the other hand, as shown in FIG. 1, a drug chute 30 and a sealing device 35 are provided on the transfer path through which the printed packets S are transferred by the printer device 10.

The medicine chute 30 synchronously supplies a certain amount of medicine to the transported double-folded packaging paper S. After this, the packaging paper S is sealed around the periphery by the sealing device 35 and becomes a medicine packaging A. becomes.

This sealing device 35 includes a driving device 40 and this driving bag!
! 2, as shown in FIG. 7(a), rotated by 40
It is composed of two heat generating rolls 41.

As shown in the figure, the heating roll 41 is an "I"-shaped heating element that is provided so as to sandwich and oppose the packaging paper S.
When it rotates once, as shown in FIG.
2 heat-seals both front and rear side edges 62.

This embodiment is configured as described above, and now, when the printer device 10 starts processing and a roll of sachet paper is set on the support shaft 1, the printer device 10 waits for data 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 10.

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 CP IJ 22 sequentially reads printing font data from the ROM memory 24 according to the input print data, and detects that the printing position of the sachet paper S has moved to the printer head 14 based on the feed amount data from the encoder 25. Upon detection, the CPU 22
The solenoid 19 corresponding to the font data is driven by the drive circuit 20, the bottle 18 is moved, and the ribbon 15 is brought into pressure contact with the packet paper S, for example, as shown in FIG. 6, printing in two rows is performed. .

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 on the packets S continuously, the lost time is accumulated, so that a significant time reduction can be achieved.

As mentioned above, the packet S on which data has been printed is sent out to the transfer path, and after a certain amount of medicine is supplied by the medicine chute 30, the periphery is sealed by the sealing device 35, and the medicine packet A becomes.

Thereafter, for example, when the print data such as the patient's name is updated, the printers W10 empty-feed the packets for several colors that are not to be printed. At this time, C of Bunrita device 10
The PU 22 requests the external terminal 29 to send new print data, and as shown in FIG. The font data for printing is read from the ROM memory 24 according to the updated data, and set in the output port 21 in preparation for the next printing. Immediately after the above-mentioned blank feed 82 is finished, the updated data is printed on the packet paper S. Start working on 84.

Therefore, as shown in FIGS. 8(a) and 8(b), compared to the conventional method, the printing end time when updating data according to the present invention is longer than that of printing data, printing time, printing processing, blank feed, etc. If the times are the same, the print processing time will be shorter for every - update. Therefore, when printing data is frequently updated, for example, when printing medicine packets with a large number of patient names in succession, the printing time can be significantly shortened.

〔effect〕

Since this invention is configured as described above, it is possible to eliminate the waiting time during which no printing is performed, which occurs after empty feeding of packaging paper, which was a problem with conventional drug packaging machines, thereby improving packaging efficiency. can be achieved.
