Description

TECHNICAL FIELD The present invention relates to a method for printing a medicine packaging paper for packaging medicines such as powders and tablets.

[Conventional technology]

The heat-fusible packaging paper is transferred in one direction, and at the time of the transportation, the packaging paper is folded in two in the width direction, or pre-folded packaging paper is sent in one direction, and the packaging paper is The transfer path is provided with a medicine supply chute and a sealing device, and an operation of intermittently supplying a fixed amount of medicine from the chute between the folds of the packaging paper and the width direction of the packaging paper by the sealing device during the transportation of the packaging paper 2. Description of the Related Art A medicine packaging device for performing continuous heat-sealing between both side edges to continuously form a packaging bag containing a fixed amount of a medicine has been known.

The packaging bag taken out from the medicine packaging device is usually stored in a medicine bag and handed to the patient, but there are many kinds of medicines packaged by the medicine packaging device, and they are very similar. There is. In addition, since it is difficult to accurately determine the type of drug from the outside when the sachet is packaged, when the sachet is stored in the medicine bag, it may be mistaken for a sachet of another patient.

These mistakes are extremely dangerous, so in recent years
As shown in FIG. 6, the packaging bag A is provided with a print B of the patient name, drug name, usage and the like.

If the printing B is performed after packaging of the medicine, the packaging bag may be broken. Therefore, the medicine is usually packaged after printing on the packaging paper.

[Problems to be Solved by the Invention]

However, when printing on a packaging paper, conventionally, when the print data such as the patient name is updated, the printer device 10 prints the data before the update 81 as shown in FIG. In order to prevent the residual medicine from being mixed in on the chute and to distinguish between the sachets A, the empty paper 82 for several sachets is fed and then the update data is printed 84. However,
In order for the printer device 10 to perform printing, it is necessary to input update data and print processing 83 for processing the input data, and printing 84 cannot be performed immediately after the end of the idle feed 82. It is in a standby state for t. Therefore, if the data is updated frequently, the waiting time repeated for each update becomes a large time loss, and there is a disadvantage that the packaging efficiency of the medicine packaging paper decreases.

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

[Means for Solving the Problems]

In order to solve the above-mentioned problems, in the present invention, a medicine packaging paper S
A printer head is provided in the transfer path for printing while moving the medicine packaging paper S with respect to the fixed printer head. At that time, for inputting update data to the printer head and printing the input. The method is adopted in which the processing is performed during the idling period of the packaging paper.

With the above-mentioned blank feeding period, when the printer device updates the data, that is, when the print data on the packing sheet is changed, in order to distinguish the remaining medicine from the medicine chute and the packing sheet,
This is a period in which the packaging paper is sent for several minutes without printing, and is appropriately determined based on experience and experiments.

[Action]

According to the above method, during the idling period of the packaging paper, the update data is input to the printer head and the process for printing the input is performed, and the updated data is printed immediately after the idling end. Therefore, at this time, if the next packaging paper is continuously carried out, the packaging can be carried out continuously without stopping the transfer of the packaging paper.

〔Example〕

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

As shown in FIG. 1, a roll body L of heat-fusible packaging paper is set on the support shaft 1, and the packaging paper S is moved to a transfer path of the packaging paper S drawn from the roll body L. There are two guide rollers 2 for guiding the. This packaging paper S is

A receiving plate 13 is provided between the guide roller 12 and the guide roller 12, and the packaging paper S is guided by the 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 has a third
As shown in the figure, they are provided at a required interval in the transport direction of the packaging paper S, and are fixed by shifting the position in the cross direction with respect to the transport direction of the packaging paper S.

Further, as shown in FIG. 2, an endless ribbon is formed inside the box body 11 so as to surround two pinter heads 14.
15 is provided, and the upper linear portion 16 of the ribbon 15 passes over the upper side of each printer head 14 and is rotated by the rotation of the motor 17 to a third position.
Transferred in the direction of the arrow in the figure.

The printer head 14 has a large number of pins 18, and the pins 18 are independently moved by a solenoid provided in 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 linearly arranged at equal intervals are provided in a double row.

As shown in FIG. 4, the solenoid 19 for independently moving the pin 18 is connected to each driver circuit 20, and the driver circuit 20 is connected to the CPU 22 via the output port 21.

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 or the like.

The output port 21 is, for example, a flip-flop or PPI (peripheral interface) having a data latch function, latches data on the data bus at the timing from the CPU 22, and drives the corresponding driver 20 to drive the solenoid 19. To work.

The CPU 22 is connected with a RAM memory 23 as a buffer memory for temporarily storing the 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 for detecting and outputting the feed amount data is connected.

The encoder 25 is, for example, an optical or magnetic rotary encoder provided between two printer heads 14 as shown in FIG. 3, and includes a detection roller 26 attached to its rotary shaft and a detection roller 26. With the pressing roller 27 that comes into contact with the roller via the packaging paper S, for example, the packaging paper S for one packaging
Printer head (including heat seal fee) in the transfer direction
When it moves above 14, the detection roller 26 rotates once and the feed amount data can be detected without error.

Further, as shown in FIG. 4, the CPU 22 is connected with an external terminal 29 such as a personal computer and an I / O port 28 such as USART or PIO for exchanging data with the BUS.
Through a control signal C such as Y or ▲ ▼, parallel transfer (Centronics) or serial transfer of data is performed with the external terminal 29.

On the other hand, as shown in FIG. 1, a medicine chute 30 and a sealing device 35 are provided in a transfer path through which the packaging paper S after being printed by the printer device 10 is transferred.

The medicine chute 30 synchronously supplies a fixed amount of medicine to the bi-folded packaging paper S that has been transferred, and thereafter, the periphery of the packaging paper S is sealed by the sealing device 35 and the medicine packaging A Becomes

The sealing device 35 is composed of a driving device 40 and two heat generating rolls 41 which are rotated by the driving device 40 as shown in FIG.

As shown in the figure, the heat-generating roll 41 is an "I" -shaped heat generating element that is provided so as to sandwich and sandwich the packaging paper S.
When it is rotated, as shown in FIG.
Heat-seals the upper width direction 61 of the packaging paper S, and the vertical bar portion 42 heat-seals the front and rear side edges 62.

This embodiment is configured as described above. Now, when the printer device 10 starts processing and sets the roll body L of the packaging paper 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.

In the printer device 10, when the print data is input,
The transfer of the packaging paper S is started at a constant speed (the transfer speed at this time is slower than the printing speed of the printer head 14), for example, the CPU 22 prints from the ROM memory 24 according to the input print data. Sequentially read the font data for, by the feed amount data from the encoder 25,
When detecting that the print position of the packaging paper S has moved to the printer head 14, the CPU 22 drives the solenoid 19 corresponding to the font data by the drive circuit 20,
The pin 18 is moved, the ribbon 15 is pressed against the packaging paper S, and two rows of printing are performed, for example, as shown in FIG.

As described above, the printer device 10 includes the printer head 14
Since the printing is performed by fixing the paper and moving the packing paper S, there is no loss time associated with the start and stop of the packing paper S and the movement time of the printer head 14 as in the conventional case, and the time required for printing Can be shortened. Therefore, particularly when printing is performed on the packaging paper S continuously, the time can be significantly shortened.

As described above, the packaging paper S on which the data is printed is sent out to the transfer path and a certain amount of the medicine is supplied by the medicine chute 30, and then the periphery is sealed by the sealing device 35,
It becomes the medicine packaging A.

After that, for example, when the print data such as the patient name is updated by the external terminal 29, the printer device 10 performs the blank feeding of the packaging paper for several packages in which printing is not performed. At this time,
The CPU 22 of the printer 10 requests the external terminal 29 to send new print data, and as shown in FIG. 8B, the print data is processed 83 during the idle feed 82, that is, for example, this printer device. In 10, the font data for printing is read from the ROM memory 24 according to the input update data and set in the output port 21 to prepare for the next printing. Immediately after the blank feed 82 is finished, the packing sheet S is printed. Start printing update data 84.

Therefore, as shown in FIGS. 8 (a) and 8 (b), the print end time at the time of updating the data according to the present invention is the print data, the print time, the print process, the idle feed, etc. If the times are the same, the print processing time t becomes shorter for each update. Therefore, when the print data is frequently updated, for example, when the medicine packages of a large number of patient names are continuously made, the print time can be greatly shortened.

Further, at this time, in the method according to the present invention, when the idle feed 82 period ends, the update data can be continuously printed on the packaging paper S without providing a processing period for printing. Therefore, if the packaging is continuously performed without stopping the transfer of the packaging paper S, the medicine packaging can be performed without causing the loss time due to the activation and the stop of the packaging paper S. it can.

〔effect〕

According to the present invention, since the update data is input to the printer head and the processing for printing the input is performed during the idling period of the packing sheet by the above method, the conventional medicine packing machine is used. It is possible to improve the packaging efficiency by eliminating the problem of the standby time for performing no printing that occurs after the blank feeding of the packaging paper.

For this reason, the update data is printed immediately after the blank feeding is completed, so if the continuous packing is performed without stopping the transport of the packaging paper after the blank feeding, It is possible to improve the packaging efficiency by avoiding the loss time associated with starting and stopping.
