Such a conventional automatic medicine packing machine, the medicine discharged from the
Korean Patent No. 10-0521720 discloses an example of a conventional printing apparatus that is mounted and used in an automatic drug packing machine. The conventional printing apparatus is printing the drug information on the outside of the wrapping paper by the thermal print head and the ribbon tape, the wrapping paper and the ribbon tape is laminated and compressed between the contact roller and the thermal print head at the moment of printing. Will be moved to.
By the way, since the ribbon tape is wound round in a reel form, the amount of the ribbon tape released is changed according to the remaining amount of the ribbon tape wound so as to have a reel form. That is, the amount of ribbon tape released at one rotation of the reel at the initial stage of which the remaining amount of ribbon tape is 100% is different from the amount of ribbon tape released at one rotation of the reel when the remaining amount of ribbon tape is almost 0%.
In the conventional printing apparatus, since the ribbon tape reel is rotated at a constant speed while ignoring this, there is a problem in that the tension of the ribbon tape is not kept constant and print quality is deteriorated.
SUMMARY OF THE INVENTION The present invention for solving the above problems is to provide a control method of a printing apparatus for an automatic pharmaceutical packaging machine that can adjust the unwinding speed of a ribbon tape by detecting the remaining amount of the ribbon tape during a printing operation.
According to the present invention for achieving the above object, a control method of a printing apparatus for printing the drug information wrapped by the thermal print head and the ribbon tape on the surface of the wrapping paper, the remaining amount of the ribbon tape is measured, and the measured ribbon A control method of a printing apparatus is provided, wherein the rate of release of the ribbon tape is adjusted based on the remaining amount of tape.
In the remaining amount measuring step of the ribbon tape, it is preferable to measure the remaining amount of the ribbon tape wound on the driven reel of the ribbon tape through the rotational speed of the driven reel detected by the encoder installed on the rotating shaft of the driven reel from which the ribbon tape is released. Do.
The remaining amount measuring step of the ribbon tape may include rotating a driving reel to which the ribbon tape is wound by rotating a driving motor, and as the ribbon tape is wound around the driving reel by rotation of the driving reel, the ribbon tape from the driven reel. And releasing the rotating reel and measuring the remaining amount of the ribbon tape wound on the driven reel from the rotational speed of the encoder installed on the rotating shaft of the driven reel.
Measuring the remaining amount of the ribbon tape, the step of detecting the encoder slit formed in the encoder by the sensor to measure the pulse value from the rotation of the driven reel, by comparing the measured pulse value with the previously stored frequency table in the control unit It is preferable to include the step of measuring the remaining amount of the ribbon tape.
In the step of adjusting the release rate of the ribbon tape, it is preferable to adjust the release rate of the ribbon tape by adjusting the rotational speed of the tension motor connected to the driven reel from which the ribbon tape is released.
Preferably, the step of adjusting the release rate of the ribbon tape includes determining a rotational speed of the tension motor by comparing the tension table previously stored in the controller with the remaining amount of the measured ribbon tape.
The rotation speed of the tension motor is preferably adjusted by increasing or decreasing the number of shorts per unit time.
Further, according to another aspect of the present invention, as a control method of a printing apparatus for printing the drug information wrapped by the thermal print head and the ribbon tape on the surface of the wrapping paper, interposing the wrapping paper and the ribbon tape between the thermal print head and the contact roller. Pressurizing; Rotating the drive reel by rotation of a drive motor to wind the ribbon tape around the drive reel to release the ribbon tape from the driven reel to rotate the driven reel; Rotating an encoder installed on the rotating shaft of the driven reel to detect rotation of the encoder slit by a sensor and calculating a pulse value per unit time from the detected value by the control unit; Determining, by the controller, the remaining amount of ribbon tape from a pre-stored pulse-remaining table; Determining, by the controller, a torque value corresponding to the remaining amount of the ribbon tape from the previously stored torque remaining amount table; Increasing the rotational speed of the tension motor by reducing the number of shots per unit time of the tension motor connected to the driven reel according to the torque value; Provided is a control method of a printing apparatus comprising a.
According to the present invention, there can be provided a control method of a printing apparatus for an automatic pharmaceutical packing machine, which can adjust the unwinding speed of the ribbon tape by detecting the remaining amount of the ribbon tape during a printing operation.
Accordingly, according to the control method of the present invention, the amount of ribbon tape released from the ribbon tape reel can be adjusted as the release speed is controlled, thereby improving print quality.
