Description

약포장기용 열전사 프린터{Thermal printer for drug envelope}Thermal printer for drug envelope

본 발명은 약포장기의 포장용지 표면에 프린트하는 약포장기용 열전사 프린터에 관한 것으로, 연속공급되는 포장용지와는 달리 감열리본은 인쇄시에만 공급되게 하여 감열리본을 크게 절약하는 것이다.The present invention relates to a thermal transfer printer for a medicine packaging machine for printing on the surface of the packaging paper of the medicine packaging machine, unlike the continuous supply of packaging paper, the thermal ribbon is to be supplied only at the time of printing significantly saving the thermal ribbon.

병원에서 사용되는 자동약포장기에는 약포장지의 표면에 환자이름, 조제일시, 복용시기, 담당의사 또는 진료번호 등을 프린트하기 위해 프린터가 장착되어 있으며, 소음과 수명이 짧은 도트프린터 대신 저소음이고 인쇄품질이 선명하며 인쇄물의 제약이 덜한 열전사프린터를 사용하고 있다.The automatic medicine packing machine used in the hospital is equipped with a printer to print the patient's name, the date of preparation, the time of taking the medicine, the doctor or the treatment number on the surface of the medicine packing paper. This crisp, low-print thermal printer is used.

열전사프린터는 인쇄를 위하여 감열리본을 사용하게 되고 상기 감열리본은 약포장용지와 함께 연속공급되어 열전사프린터 헤드로 약포장용지 표면에 프린트시키게 되므로 약포장용지와 감열리본의 사용길이는 같게 된다.The thermal transfer printer uses a thermal ribbon for printing, and the thermal ribbon is continuously supplied with the chemical packaging paper and printed on the surface of the chemical packaging paper by the thermal transfer printer head, so that the length of use of the chemical packaging paper and the thermal ribbon is the same. .

즉 프린트가 끝난 약포장용지(3)와 감열리본(11)은 도 6 의 (가)(나)와 같이 인쇄위치가 동일하여 약포장용지(3)와 감열리본(11)의 사용길이는 같을 수 밖에 없다.That is, the printed packaging paper 3 and thermal ribbon 11 have the same printing position as shown in FIG. 6A, so that the length of use of the packaging paper 3 and thermal ribbon 11 is the same. There is no choice but to.

그러나 약포장용지(3)와 감열리본(11)의 사용길이가 같을 경우 프린트가 끝난 감열리본(11)은 실제 인쇄되는 구간(A) 보다 인쇄되지 않고 지나간 구간(B)이 많아 불필요하게 감열리본(11)의 많은부분(즉 B 부분)이 소모되는 문제점이 있다.이러한 문제점을 해결하기 위해 인쇄시만 인쇄리본을 이송시키는 선행기술이 미국 특허 제5137378호가 있으나,상기 선행기술은 인쇄리본의 이송이 모터에 직결된 원형기어로 이루어지고 이송로울러의 수가 많으며, 리본 이송을 차단하기 위해 마찰클러치를 사용하고 또한 정지시 리본의 처짐을 방지하기 위해 솔레노이드로 리본이 장착된 롤을 브레이크식으로 제어하며, 인쇄시 미리 정해진 량만큼 리본이 이송되게 하고 있다.이러한 선행기술은 인쇄리본의 이송에 따른 로울러수가 많고 모터에 직결된 이송로울러를 사용하는 한편 마찰클러치 사용 및 텐션을 잡아주기 위해 브레이크방식을 채택하고 있어 구조적으로 취약하고 소음도 많으며 특히 리본의 이송이 인쇄량만큼 이송하지 않고 정해진 량만큼 이송되어 실질적으로 리본 절약 효과가 덜하며, 용지 이송속도에 관계없는 인쇄가 이루어져 이송속도가 변할 경우 글자가 선명하게 인쇄되지 못하는 것이었다.However, when the length of use of the weakly wrapped paper 3 and the thermal ribbon 11 is the same, the thermal ribbon 11 that has been printed is not printed more than the actual printed section A, and thus the unneeded thermal ribbon is unnecessary. There is a problem in that a large part (ie part B) of (11) is consumed. In order to solve such a problem, there is a prior art which transfers a print ribbon only when printing. It is composed of a circular gear directly connected to this motor and has a large number of feed rollers. It uses a friction clutch to block ribbon transfer, and brake-controlled rolls equipped with ribbons with solenoids to prevent sagging of ribbons when stopped. In this prior art, the number of rollers according to the transfer of the printing ribbon is large and the rollers directly connected to the motor are used. On the other hand, the brake method is adopted to hold the friction clutch and tension, which is structurally weak and noisy. In particular, the ribbon is conveyed by a fixed amount rather than by the amount of printing, so the ribbon saving effect is substantially less. If the printing speed was changed due to irrelevant printing, the letters could not be printed clearly.

본 발명은 약포장지는 연속공급시키되 감열리본은 인쇄시에만 공급되게 하여 인쇄종료시점부터 다음 인쇄시작시점까지는 감열리본의 공급이 중단되게 하므로써 감열리본이 불필요하게 허실되는 경우를 없애도록 하는 것이다.The present invention is to provide a continuous supply of weak packaging paper, so that the thermal ribbon is supplied only when printing so that the supply of the thermal ribbon is stopped from the end of printing until the next printing start to eliminate the case that the thermal ribbon is unnecessarily lost.

이러한 본 발명은 연속공급되는 약포장용지에 감열리본을 대고 열전사 헤드를 이용하여 인쇄를 행함에 있어서, 약포장용지에 밀착되어 약포장용지를 이송시키는 지지롤러와, 지지롤러 하부에 설치되고 상하이동되는 열전사헤드와, 리본공급릴에서 풀려 리본권취롤에 감기는 감열리본의 텐션을 조절하는 텐션조절봉과, 리본권취릴을 회전시키는 모터와, 열전사헤드를 상하이동시키는 솔레노이드와, 리본공급릴의 회전을 단속하는 솔레노이드와, 상기 모터와 솔레노이드의 구동을 단속하는 콘트롤수단을 구비시킴으로써 이루어진다.The present invention is a printing roller by applying a thermal ribbon to a continuous supply of a weak packaging paper, using a thermal transfer head, the support roller to be in close contact with the weak packaging paper for transporting the weak packaging paper, installed on the lower support roller Thermal transfer head to be moved, tension adjusting rod to adjust tension of thermal ribbon which is unwound from ribbon supply reel and wound on ribbon winding roll, motor to rotate ribbon winding reel, solenoid to move thermal transfer head to shanghai, ribbon supply And a control means for controlling the driving of the motor and the solenoid.

본 발명은 인쇄시작시점에서 열전사헤드를 상부로 이동시켜 지지롤러에 접촉된 약포장용지에 감열리본을 밀착시키며 인쇄를 행하게 하므로써 인쇄시에는 약포장용지의 공급량과 동일한 감열리본이 공급되고, 인쇄가 불필요한 시점에서는 열전사헤드를 하부로 이동시켜 감열리본을 약포장용지와 접촉을 차단시킴으로써 감열리본의 공급은 중단되고 약포장용지만 공급되게 하여 감열리본에 인쇄되지 않은 부분이 발생되지 않고 연속적으로 사용할 수 있도록 하여 감열리본을 절약하는 것이다.In the present invention, the thermal ribbon is moved to the upper portion at the start of printing, and the thermal ribbon is brought into close contact with the weak packaging paper in contact with the support roller to perform printing, so that the thermal ribbon equal to the supply amount of the weak packaging paper is supplied during printing. When the heat transfer head is not needed, the thermal ribbon is moved downward to block the thermal ribbon from contact with the weak packaging paper, so that the thermal ribbon is stopped and only the weak packaging is supplied, so that the unprinted part of the thermal ribbon is not generated. To save thermal ribbon.

즉 본 발명은 열전사헤드로 약포장용지에 인쇄를 할때에만 감열리본이 사용되고 인쇄를 하지 않을때는 감열리본의 이동을 중단시키는 것이다.That is, according to the present invention, the thermal ribbon is used only when printing on a weakly packaged paper using a thermal transfer head, and the thermal ribbon is stopped when the thermal ribbon is not printed.

본 발명은 약포장기(1)에 있어서, 용지공급릴(2)에서 연속공급되는 약포장용지(3)에 감열리본(11)을 대고 열전사헤드(20)로 약포장용지(3) 표면에 필요글자를 인쇄시키는 것이다.In the present invention, in the medicine packaging machine (1), the thermal ribbon (11) is applied to the medicine packaging paper (3) continuously fed from the paper feed reel (2), and the thermal transfer head (20) is applied to the medicine packaging paper (3) surface. You need to print the letters.

약포장용지(3)는 용지공급릴(2)에서 풀려 지지롤러(22)에 밀착되며 후단의 약포장수단으로 연속공급되며 이때 엔코더(4)를 약포장용지(3)에 밀착시켜 약포장용지(3)의 이송속도를 엔코더(4)에서 검출하게 한다.The medicine packaging paper 3 is unwound from the paper feed reel 2 and closely adhered to the support roller 22, and is continuously supplied by the medicine packaging means at the rear end. At this time, the encoder 4 is brought into close contact with the medicine packaging paper 3 The feed rate of (3) is detected by the encoder (4).

감열리본(11)은 리본공급릴(10)에 감겨진 상태에서 지지롤러(22)하부와 가이드롤러(13)를 거친 후 텐션조절봉(14)에 감겨진 상태로 리본권취릴(12)에 감겨진다.The thermal ribbon 11 passes through the lower portion of the support roller 22 and the guide roller 13 in the state of being wound on the ribbon supply reel 10 and then to the ribbon winding reel 12 in the state of being wound on the tension adjusting rod 14. It is wound.

여기서 리본권취릴(12)은 모터(23)의 회전동력을 회전릴(24)을 거쳐 전달받는 구동릴(25)에 의해 회전되어지고, 리본공급릴(10)의 배면에는 스톱기어(18)를 형성시켜 스프링(19)에 텐션지지된 스톱퍼(17)가 치합되게 한다.Here, the ribbon winding reel 12 is rotated by a drive reel 25 which receives the rotational power of the motor 23 via the rotary reel 24, and a stop gear 18 on the rear surface of the ribbon supply reel 10. The stopper 17 tension-supported to the spring 19 is engaged.

상기 스톱퍼(17)는 솔레노이드(17)의 작동에 의해 밀려나게 구성된다.The stopper 17 is configured to be pushed out by the operation of the solenoid 17.

텐션조절봉(14)은 감열리본(11)에 감긴 채로 장홈(15)을 타고 상,하이동되며 장홈(16)의 하부에는 텐션조절봉(14)을 감지하는 센서(16)가 부착된다.The tension adjusting rod 14 is moved up and down in the long groove 15 while being wound on the thermal ribbon 11, and a sensor 16 for detecting the tension adjusting rod 14 is attached to the lower portion of the long groove 16.

열전사헤드(20)는 지지롤러(22)하부에 상,하이동되게 설치되는 것으로 솔레노이드(26)로 구동봉(21)을 밀게되면 열전사헤드(20)가 상부로 이동되면서 감열리본(11)을 약포장용지(3)에 밀착시키며 인쇄하게 되고 솔레노이드(26)의 미는 힘이 없어지면 열전사헤드(20)는 자중에 의해 원위치되어진다.The thermal transfer head 20 is installed to move up and down under the support roller 22. When the driving rod 21 is pushed by the solenoid 26, the thermal transfer head 20 is moved to the upper portion of the thermal ribbon 11. ) Is adhered to the medicine packaging paper (3) and the printing and the thermal transfer head 20 is in place by its own weight when the pushing force of the solenoid 26 is lost.

그리고 모터(23)와 솔레노이드(26)(27)의 구동을 제어하고 센서(16)와 엔코더(4)의 출력을 인식하는 한편 인쇄를 제어하는 콘트롤수단이 도시되지 않았지만 구비되어진다.Control means for controlling the driving of the motor 23 and the solenoids 26 and 27, recognizing the output of the sensor 16 and the encoder 4, and controlling printing are provided although not shown.

이러한 구성의 본 발명에서 약포장지(3)에 약을 담아 포장하는 약포장기(1)는 공지된 기술로써 이에 대한 설명은 생략하며 본 발명의 구성에 필요한 용지공급릴(2)에 대하여만 설명한다.In the present invention of this configuration, the medicine packaging machine (1) for packing medicine in the medicine packaging paper (3) is a well-known technique, the description thereof will be omitted and only the paper feed reel (2) necessary for the configuration of the present invention will be described. .

용지공급릴(2)에 감긴 약포장용지(3)는 지지롤러(22)에 밀착되며 후단의 포장부로 이송되며 상기 용지공급릴(2)은 후단에서 약포장용지(3)를 당기는 힘에 의하여 약포장용지(3)를 풀어주게 된다.The weak packing paper (3) wound on the paper feed reel (2) is in close contact with the support roller 22 and transported to the rear packing part, and the paper feed reel (2) is pulled by the force of pulling the weak packing paper (3) from the rear end. Unpack the medicine packaging paper (3).

이때 지지롤러(22)는 약포장용지(3)에 밀착되어 약포장용지(3)의 이송에 따라 회전하게 된다.At this time, the support roller 22 is in close contact with the medicine packaging paper (3) is rotated in accordance with the transport of the medicine packaging paper (3).

감열리본(11)은 리본공급릴(10)에 감긴 상태에서 지지롤러(22)하부를 거쳐 가이드롤러(13)에 밀착된 후 텐션조절봉(14)을 끼고 리본권취릴(12)에 감기게 된다.The thermal ribbon 11 is in close contact with the guide roller 13 through the lower portion of the support roller 22 in the state of being wound on the ribbon supply reel 10, and then, the tension adjusting rod 14 is fitted to the ribbon winding reel 12. do.

이때 감열리본(11)은 지지롤러(22)에 밀착된 약포장용지(3)에 닿지 않은 상태가 되게 한다.At this time, the thermal ribbon 11 is not in contact with the medicine packaging paper (3) in close contact with the support roller (22).

이상태에서 약포장용지(3)의 인쇄초기 위치가 되면 콘트롤수단에서는 솔레노이드(26)를 작동시켜 구동봉(21)을 밀어줌과 동시에 솔레노이드(27)를 작동시켜 스톱퍼(17)를 밀어준다.In this state, when the initial position of the medicine packaging paper 3 is printed, the control means operates the solenoid 26 to push the driving rod 21 and simultaneously operates the solenoid 27 to push the stopper 17.

솔레노이드(26)가 구동봉(21)을 밀면 열전사헤드(20)가 상부로 이송되면서 감열리본(11)을 약포장용지(3)에 밀착시키며 인쇄를 시작한다.When the solenoid 26 pushes the driving rod 21, the thermal transfer head 20 is transferred upward, and the thermal ribbon 11 is brought into close contact with the medicine packaging paper 3 to start printing.

열전사헤드(20)가 감열리본(11)을 약포장용지(3)에 밀착시키면 이송되는 약포장용지(3)와 함께 감열리본(11)이 이송되며 이때 콘트롤수단의 제어에 의해 열전사헤드(20)로 약포장용지(3)표면에 인쇄를 하게 된다.When the thermal transfer head 20 closely adheres the thermal ribbon 11 to the weak packaging paper 3, the thermal ribbon 11 is transferred together with the weak packaging paper 3 to be transferred. At this time, the thermal transfer head is controlled by the control means. (20) to print on the surface of the weak packaging (3).

열전사헤드(20)가 감열리본(11)을 약포장용지(3)에 밀착시켜 감열리본(11)이 이송되면 텐션조절봉(14)이 장홈(15)을 타고 하향이동되어 센서(16)에 의해 감지되어지고 이때부터 모터(23)를 회전시켜 리본권취릴(12)을 회전시킨다.When the thermal transfer head 20 adheres the thermal ribbon 11 to the medicine packaging paper 3 and the thermal ribbon 11 is transported, the tension adjusting rod 14 moves downward through the long groove 15 so that the sensor 16 is moved. It is detected by the rotation of the ribbon winding reel 12 by rotating the motor 23 from this time.

리본공급릴(10)은 열전사헤드(20)가 감열리본(11)에 밀착될때부터 자유롭게 감열리본(11)을 풀어준다.The ribbon supply reel 10 frees the thermal ribbon 11 from the time when the thermal transfer head 20 is in close contact with the thermal ribbon 11.

따라서 감열리본(11)이 이송되면(인쇄가 진행되는 상태) 리본권취릴(12)에서 인쇄가 끝나 이송된 감열리본(11)을 감아주게 된다.Therefore, when the thermal ribbon 11 is transported (printing is in progress), the ribbon is wound around the thermal ribbon 11 after the printing is finished in the ribbon winding reel 12.

그러나 인쇄가 종료되면 콘트롤수단에서 솔레노이드(26)작동을 해제시켜 열전사헤드(20)가 하향이동되게 하는 한편 솔레노이드(27)의 작동도 해제시켜 스톱퍼(17)가 스프링(19)의 텐션에 의해 스톱기어(18)에 물리게하므로써 리본공급릴(10)은 회전이 중단되고 아울러 인쇄동작도 중단되며 더이상 감열리본(11)의 이송도 중단된다.However, when printing is finished, the solenoid 26 is released from the control means so that the thermal transfer head 20 is moved downward, while the solenoid 27 is also released, thereby stopping the stopper 17 by the tension of the spring 19. The ribbon feed reel 10 is stopped by rotating the stop gear 18, the printing operation is also stopped, and the transfer of the thermal ribbon 11 is no longer stopped.

그러나 모터(23)는 바로 정지하지 않고 감열리본(11)을 계속 감아주며 리본권취릴(12)에서 감열리본(11)이 공급되지 않는 상태로 감열리본(11)을 감아줄수록 감열리본(11)은 긴장되며 이로 인하여 텐션조절봉(14)은 센서(16)에서 감지되지 않게 장홈(15)을 타고 상부로 이송된다.However, the motor 23 continues to wind the thermal ribbon 11 without stopping and the thermal ribbon 11 is wound as the thermal ribbon 11 is not supplied from the ribbon winding reel 12. ) Is tensioned, and thus the tension adjusting rod 14 is transported upward through the long groove 15 so as not to be detected by the sensor 16.

센서(16)에서 텐션조절봉(14)이 감지되지 않으면 콘트롤수단에서는 모터(23)구동을 정지시킨다.If the tension adjusting rod 14 is not detected by the sensor 16, the control means stops driving the motor 23.

이상태가 약봉지 1칸에 대한 인쇄가 종료된 상태이며 이때 감열리본(11)은 이송이 중단되었지만 약포장용지(3)는 게속적으로 이송되고 있는 상태가 된다.In this state, the printing of one medicine bag is finished, and the thermal ribbon 11 is stopped, but the medicine packaging paper 3 is continuously being transferred.

따라서 다음번 인쇄초기위치가 되면 콘트롤수단에서는 다시 솔레노이드(26)(27)를 작동시켜 스톱퍼(17)를 스톱기어(18)에서 해제시키는 한편열전사헤드(20)를 감열리본(11)과 함께 약포장용지(3)에 밀착시킴으로써 전술된 바와 같이 인쇄동작이 진행된다.Therefore, when the next printing initial position is reached, the control means operates the solenoids 26 and 27 again to release the stopper 17 from the stop gear 18 and the thermal transfer head 20 together with the thermal ribbon 11. By adhering to the wrapping paper 3, the printing operation proceeds as described above.

이같이 본 발명은 열전사헤드(20)로 약포장용지(3)표면에 인쇄를 하는 인쇄초기위치에서부터 인쇄종료위치까지의 길이만큼만 감열리본(11)이 이송되게되므로 도 6 의 (다)와 같이 감열리본(11)은 인쇄구간(A)만 나타나고 인쇄가 되지 않는 구간(B)은 거의 나타나지 않게 된다.As such, the present invention transfers the thermal ribbon 11 only as long as the length from the initial printing position to the end printing position to print on the surface of the weak packaging paper 3 by the thermal transfer head 20, as shown in FIG. In the thermal ribbon 11, only a printing section A appears, and a section B which is not printed is hardly shown.

따라서 도 6 의 (나)와 같은 상태로 인쇄할 경우에 비하여 감열리본(11)의 소모량이 극히 적어 감열리본(11)을 절약할 수 있다.Therefore, compared to the case of printing in the state as shown in (b) of FIG. 6, the consumption of the thermal ribbon 11 is extremely small, thereby saving the thermal ribbon 11.

본 발명의 엔코더(4)는 약포장용지(3)의 이송속도를 감지하여 열전사헤드(20)에서 약포장용지(3)에 인쇄하는 인쇄속도를 조절하므로써 약포장용지(3)의 이송속도가 변하더라도 최적의 상태로 인쇄가 되게 한다.The encoder 4 of the present invention detects the feed rate of the weakly packed paper 3 and adjusts the printing speed of printing on the weakly packed paper 3 from the thermal transfer head 20 so as to adjust the feed rate of the weakly packed paper 3. Even if is changed, it will print in an optimal state.

본 발명은 연속공급되는 약포장지의 표면에 감열리본을 대고 열전사헤드로 인쇄시킴에 있어서, 인쇄가 진행되는 동안에만 감열리본을 이송시키고 인쇄가 진행되지 않는 동안에는 감열리본의 이송을 중단시킴으로써 약포장지와 같은 길이로 소모되었던 감열리본의 사용량을 크게 줄일 수 있으며,구동시 소음이 발생되지 않고 간단한 구조로 감열리본의 사용량을 최소화시키게 된다.In the present invention, the thermal ribbon is placed on the surface of the continuously supplied weak packaging paper, and the thermal transfer head is used to transfer the thermal ribbon only while the printing is in progress and stop the transfer of the thermal ribbon while the printing is not in progress. It can greatly reduce the amount of thermal ribbon that was consumed in the same length, and minimize the amount of thermal ribbon with a simple structure without generating noise during driving.
