이하 본 발명의 구성 및 작용을 첨부도면 도 2 내지 도 5 를 참조하여 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described with reference to FIGS. 2 to 5.

본 발명인 치과주조용 금합금 절단기의 구성은 커팅다이(120)상에 로고펀치(130)와 커터(110)가 상하 왕복하게 설치되며, 그 하부에 절단된 단위소재(1b)가 배출되어지는 배출구(150)를 갖는 절단부(100)와, 상기 절단부(100)에 소재(1a)를 자동공급하는 소재자동공급부(200)와, 상시 배출구(150)에 위치하여 단위소재(1b)를 계측하는 계측선별부(300)와 작동과정을 제어하는 제어부(400)로 이루어진다.In the present invention, the dental cast gold alloy cutter includes a logo punch 130 and a cutter 110 installed up and down on the cutting die 120, and a discharge port through which the cut unit material 1b is discharged. Measurement unit for measuring the unit material (1b) is located in the cutting unit 100 having a 150, the automatic material supply unit 200 for automatically supplying the material (1a) to the cutting unit 100, and the discharge port 150 at all times The control unit 400 for controlling the operation unit 300 and the operation process.

특히, 소재자동공급부(200)는 일단부가 절단부(100)의 커팅다이(120)에 접하는 베이스(210)와, 상기 베이스(210)상에 설치되는 서보모터(220)와, 상기 서보모터(220)와 축연결되는 리드 스크류(230)와, 상기 리드스크류(230)와 나사결합되며 소재고정구(241)가 설치된 소재이송대(240)와, 상기 소재이송대(240)의 양측에서 가이드하는 소재이송대 레일(250)과, 상기 소제이송대(240) 상의 이송방향으로 설치되며 가이드홈(261)을 따라 소재(1a)를 절단부(100)로 안내하는 소재가이드(260)로 이루어진다.In particular, the automatic material supplying part 200 has a base 210 having one end contacting the cutting die 120 of the cutting part 100, a servo motor 220 installed on the base 210, and the servo motor 220. Lead screw 230, which is axially connected to the screw, and the material screw (240) screwed to the lead screw 230 and the material fixing tool 241 is installed, and the material carrier rail guides from both sides of the material carrier 240 And a material guide 260 installed in the transport direction on the cleaning carriage 240 and guiding the material 1a to the cutting part 100 along the guide groove 261.

계측선별부(300)는 절단부(100)의 배출구(150) 상에 설치되며 상부에 깔대기 형상의 도입구(311)가 형성되며 양측부에 통공(313)이 형성되며 양측하부에 토출구(312)가 형성된 계측관(310)과, 상기 각각의 통공(313)에 분사구(321)가 일정깊이 만큼 삽입되되 통공(313)에 간섭되지 않게 설치되는 에어분사기(320)와, 상기 계측관(310)의 하부를 지지하여 단위소재(1b)가 계측관 내에 낙하 하면 그 중량을 계측하여 계측된 데이터를 제어부(400)로 전송하는 계측저울(330)로 이루어진다.The measurement selection unit 300 is installed on the outlet 150 of the cutting unit 100, the funnel-shaped inlet 311 is formed in the upper portion, the through hole 313 is formed on both sides and the discharge port 312 at both lower sides Is formed in the measuring tube 310 and the respective injection holes 313, the injection hole 321 is inserted into a predetermined depth so as not to interfere with the through hole 313, the injection pipe 320 and the measuring tube 310 Supporting the lower portion of the unit material (1b) falls in the measuring tube consists of a measuring scale 330 for measuring the weight and transmitting the measured data to the control unit 400.

상기에서 계측관(310)과 에어분사기(320)는 통공(313)을 통하여 접촉되지 않게 설치되므로 계측관(310)은 에어분사기(320)이 하중의 영향을 받지않는 자유로운 상태이다.Since the measuring tube 310 and the air injector 320 is installed so as not to contact through the through hole 313, the measuring tube 310 is in a free state in which the air injector 320 is not affected by the load.

제어부(400)는 상기 계측선별부(300)에서 계측되어진 중량 데이터를 전송받아 설정치와 비교하여, 설정치에 부합되면 배출에어분사기를 작동시키고, 설정치에 부합되지 않으면 제거 에어분사기를 작동시킴과 동시에 소재자동공급부의 서보모터의 회전각도를 조절하여 소재이송대의 이송거리를 미세조절하여 단위소재의 중량 오차를 실시간으로 보정한다.The control unit 400 receives the weight data measured by the measurement selection unit 300 and compares with the set value, and if the set value is met, operates the discharge air injector, if it does not meet the set value, operates the removal air injector and at the same time By adjusting the rotation angle of the servo motor of the automatic feeder, the feed distance of the material carrier is finely adjusted to compensate for the weight error of the unit material in real time.

이하 본 발명의 동작과정을 설명하면 다음과 같다.Hereinafter will be described the operation of the present invention.

우선 제어부(400)에는 절단되어진 단위소재(1b)를 10개 단위로 10g을 설정치로 하여 가감0.3g 범위 내에 들어가는 단위소재를 합격품으로 판정하고 범위을 벗어나는 단위소재를 불합격처리 명령이 입력되어 있다.First, the control unit 400 determines that the unit material falling within the range of 0.3g is set as 10g for 10 units of the cut unit material 1b, which is cut, and a command for rejecting the unit material out of the range is input.

이와 같이 설정한 설정치를 기준값으로 하여 절단과정이 시작된다.The cutting process starts with the set value set as above as the reference value.

우선 일정길이를 갖는 스트립 상의 금 합금(예: 두께 1mm이하, 길이 800~1200mm,폭 8mm)인 소재(1a)의 중량을 측정하여 절단되어질 단위소재(1b)가 1g을 가질수 있도록 절단길이를 계산하여 제어부(400)에 세팅한다.First, the cutting length is calculated so that the unit material 1b to be cut may have 1g by measuring the weight of the material 1a of a gold alloy on a strip having a certain length (for example, thickness less than 1mm, length 800 ~ 1200mm, width 8mm). To set the control unit 400.

이후 소재(1a)의 일단부를 나사고정식의 소재고정구(241)에 고정시키며 소재가이드(260)의 가이드홈(261)상에 안착시켜 타단부가 커팅다이(120)상에 위치되도록한다.Thereafter, one end of the material 1a is fixed to the material fixing tool 241 of the screw type and seated on the guide groove 261 of the material guide 260 so that the other end is positioned on the cutting die 120.

또한 계측저울(330)은 계측관(310)의 중량을 감안하여 세팅된다.In addition, the measurement scale 330 is set in consideration of the weight of the measurement tube 310.

그리고 서보모터(220)가 회전하면 소재이송대(240)를 절단기(100)측으로 이송시키게 되므로 소재(1a)가 커터(110)와 로고펀치(130) 하에 위치하게 된다.When the servo motor 220 rotates, the material transfer table 240 is transferred to the cutter 100, so the material 1a is positioned under the cutter 110 and the logo punch 130.

특히, 서보모터(220)는 1.8°를 1 스텝으로 하므로 200 스텝으로 모터의 1회전이 이루어지며, 리드스크류(230)의 리드간격이 5mm이므로 1스텝당 소재이송대(240)의 진행거리는 0.025mm이므로 소재이송대(240)의 미세진행이 가능하게 한다.In particular, since the servo motor 220 has 1.8 ° in one step, one rotation of the motor is made in 200 steps. Since the lead spacing of the leadscrew 230 is 5 mm, the travel distance of the material carrier 240 per step is 0.025 mm. Therefore, the fine transfer of the material transfer table 240 enables.

이후, 소재(1a)의 최초 도입부의 불규칙한 면을 절단한다.Thereafter, the irregular surface of the initial introduction portion of the raw material 1a is cut off.

이후, 서보모터(220)가 회전하여 절단소재(1a)가 전진하여 다음 절단부위가 커터(110) 및 로고펀치(130) 하에 위치되게 하며,Then, the servo motor 220 is rotated so that the cutting material 1a is advanced so that the next cutting portion is positioned under the cutter 110 and the logo punch 130,

이후, 커터(110)와 로고펀치(130)가 하강하며 소재(1a)를 절단 및 로고펀칭하여 배출구(150)로 배출시킨다.Thereafter, the cutter 110 and the logo punch 130 are lowered, and the material 1a is cut and logo punched to be discharged to the outlet 150.

배출구(150)로 배출된 단위소재(1b)는 도입구(311)를 통해 계측관(310) 내에 적재되며 이와같이 연속적으로 10개의 단위소재(1b)가 적재된다.The unit material 1b discharged to the discharge port 150 is loaded into the measurement tube 310 through the introduction port 311, and 10 unit materials 1b are continuously loaded in this way.

이후 계측저울(330)이 10개의 단위소재(1b)의 중량을 계측하여 제어부(400)에 그 결과를 전송한다.Thereafter, the measurement scale 330 measures the weight of the ten unit materials 1b and transmits the result to the controller 400.

이후 제어부(400)는 전송받은 중량값 데이터를 설정된 기준값과 비교하여 오차범위내에 들어가면 합격판정을 하여 계측관(310)의 양측에 설치된 에어분사기(320)중 일측의 에어분사기(320a)를 작동시킨다.After that, the controller 400 compares the transmitted weight value data with a set reference value and falls within an error range, and makes a pass decision to operate the air injector 320a of one side of the air injectors 320 installed on both sides of the measurement tube 310. .

상기 에어분사기(320a)에서 분출되는 공기가 계측관(310) 내의 적재된 단위소재(1b)를 계측관 타측으로 강제 이송시키며 타측의 토출구(312)로 토출되게하여 토출구(312) 하에 위치한 합격품 적재함(313)에 적재된다.The air ejected from the air injector 320a forcibly transfers the unit material 1b loaded in the measurement tube 310 to the other side of the measurement tube, and is discharged to the discharge port 312 on the other side to load the pass product placed under the discharge port 312. 313 is loaded.

여기서, 상기 제어부(400)가 전송받은 중량값 데이터를 설정된 기준값과 비교하여 오차범위를 벗어나면 불합격판정을 하여 계측관(310)의 양측에 설치된 에어분사기(320)중 타측의 에어분사기(320b)를 작동시킨다.Here, if the control unit 400 compares the weight value data transmitted with the set reference value and is out of the error range, it is determined to fail and the other air injectors 320b of the air injectors 320 installed on both sides of the measurement pipe 310 are disposed. Activate

상기 에어분사기(320b)에서 분출되는 공기가 계측관(310) 내의 적재된 단위소재(1b)를 계측관 일측으로 강제 이송시키며 일측의 토출구(312)로 토출되게하여 토출구(312) 하에 위치한 불합격품 적재함(314)에 적재된다.The air ejected from the air injector 320b forcibly transfers the unit material 1b loaded in the measurement tube 310 to one side of the measurement tube, and is discharged to the discharge port 312 on one side, thereby stacking the rejects located under the discharge port 312. 314 is loaded.

이와 동시에 상기 제어부(400)는 소재자동이송부(200)의 서보모터(220)의 회 전각도를 조절하여 절단소재(1a)의 절단길이를 보정하여 다음으로 절단되어지는 단위소재(1b)의 중량이 기준값의 허용 오차범위에 들수 있게끔 조절한다.At the same time, the control unit 400 adjusts the rotation angle of the servo motor 220 of the automatic material transfer unit 200 to correct the cutting length of the cutting material 1a and then to the next cutting of the unit material 1b. Adjust the weight so that it is within the tolerance range of the reference value.
