본 고안은 브이씨알 테이프의 초기, 말기 감지장치에 관한 것으로 특히 감지장치가 광케이블을 이용하여 구성함으로써 수광부의 부품수를 줄이고 수광부를 설치하는 장소를 자유로히 선택하여 설계할 수 있도록 한 것이다.The present invention relates to the early and terminal sensing device of the V-Ral tape. In particular, the sensing device is configured by using an optical cable to reduce the number of parts of the light receiving unit and to freely select a place for installing the light receiving unit.
종래 브이씨알 테이프의 초기, 말기 감지장치는 제1도 및 제2도와 같이 테이프(1)가 감기고 풀리는 릴(2)(3)과 상기 릴(2)(3)에 의하여 이송되는 테이프(1)의 초기와 말기를 감지하기 위하여 빛을 반사하는 리드램프(4)와 상기 리드램프(4)에서 발사된 빛을 수광하는 수광센서(5)(5')를 브라켓(6)(6')에 각각 구성하였다.The early and end detection devices of the conventional V-Ral tape are reels (2) (3) to which the tape (1) is wound and unrolled as shown in FIGS. 1 and 2, and the tape (1) to be conveyed by the reels (2) (3). In order to detect the beginning and the end of the lamp (6) and the lead lamp (4) reflecting light and the light receiving sensor (5) (5 ') for receiving the light emitted from the lead lamp (4) Each was configured.
그리고, 수광센서(5)(5')에 의하여 감지된 빛이 전기적 신호로 바꾸어 와이어(7)(7')에 의하여 마이콤에 각각 전달하도록 하였다.Then, the light sensed by the light receiving sensors 5 and 5 'is converted into an electrical signal and transmitted to the microcomputers by the wires 7 and 7', respectively.
그리고, 릴(2)(3)에 감기거나 풀리거나 하는 테이프(1)의 초기나 말기가 브라켓(6)(6')에 형성된 수광센서(5)(5')의 앞을 지나게 되면 리드램프(4)에서 발사된 빛이 수광센서(5)(5')에 비치게 된다.And, when the beginning or end of the tape (1) that is wound or unwound on the reel (2) (3) passes the front of the light receiving sensor (5) (5 ') formed in the bracket (6) (6') lead lamp Light emitted from (4) is reflected on the light receiving sensors 5 and 5 '.
따라서, 수광센서(5)(5')는 리드램프(4)에서 발사된 빛을 전기적 신호로 바꾸어 와이어(7)(7')를 통하여 마이콤에 전달하여 테이프(1)의 초기나 말기임을 감지토록 하였다.Accordingly, the light receiving sensor 5 or 5 'converts the light emitted from the lead lamp 4 into an electrical signal and transmits the light to the microcomputer through the wires 7 and 7' to detect the beginning or end of the tape 1. It was forever.
그러나, 이와 같은 구성은 수광센서의 취부위치가 한정되어지기 때문에 이에 따른 부가적 구조물 설계코자 할때는 위치에 대한 설계가 자유롭지 못한 문제가 발생하며, 기능이 동일하면서도 위차가 다르기 때문에 수광센서를 두개 설치해야 하는 문제점이 발생하였다.However, this configuration has a problem that the installation position of the light receiving sensor is limited, so when designing additional structures according to this configuration, the design of the position is not free. The problem occurred.
본 고안은 이러한 점을 감안하여 고안한 것으로서 릴에 의하여 감기고 풀리는 테이프의 초기나 말기임을 감지하기 위하여 리드램프에서 발사된 빛을 광케이블이 받아 수광센서로 전달함으로써 수광센서의 설치장소에 제약을 받지 않으므로 설계상의 자유도가 높아지도록 하는데 목적이 있다.The present invention was devised in consideration of this point, and since the optical cable receives the light emitted from the lead lamp and transmits it to the light receiving sensor in order to detect the beginning or end of the tape wound and unwound by the reel, The purpose is to increase the degree of freedom in design.
본 고안은 브이씨알 테이프의 초기, 말기 감지장치를 제3도 내지 제5도에 의하여 설명한다.The present invention will be described with reference to Figs.
테이프(101)가 감기고 풀리는 릴(102)(102)과, 상기 릴(102)(103)에 이송되는 테이프(101)의 초기와 말기를 감지하기 위하여 빛을 반사하는 리드램프(104)를 형성한 것에 있어서, 상기 리드램프(104)에서 발사된 빛을 받아 전달하는 광케이블(105)(105')과 상기 광케이블(105)(105')에 의하여 전달된 빛을 수광하는 수광부와 상기 수광부에 의하여 빛을 전기적 신호로 바꾸어 와이어(107)에 의하여 신호처리부로 전달하도록 구성하였다.A reel 102 and 102 on which the tape 101 is wound and unwound, and a lead lamp 104 that reflects light to sense the beginning and end of the tape 101 conveyed to the reel 102 and 103. In one embodiment, by the light receiving unit and the light receiving unit for receiving the light transmitted by the optical cable 105, 105 'and receiving the light emitted from the lead lamp 104 and the optical cable 105, 105' The light is converted into an electrical signal and configured to be transmitted to the signal processor by the wire 107.
그리고, 상기 수광부는 수광센서(106)로 구성되었다.In addition, the light receiving unit includes a light receiving sensor 106.
이와 같이 구성된 본 고안의 작용효과를 제3도 내지 제5도에 의하여 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above with reference to FIGS. 3 to 5 as follows.
릴(102)(103)에 의하여 감기거나 풀리거나 하는 테이프(101)의 초기나 말기가 광케이블(105)(105')의 선단앞을 지나게 되면 리드램프(104)에서 발사된 빛이 광케이블(105)(105')의 선단에 비치게 된다.When the beginning or end of the tape 101, which is wound or unwound by the reels 102 and 103, passes in front of the tip of the optical cables 105 and 105 ′, the light emitted from the lead lamp 104 is transmitted to the optical cable 105. At the tip of 105).
따라서, 빛은 광케이블(105)(105')에 의하여 수광센서(106)로 전달된다.Therefore, light is transmitted to the light receiving sensor 106 by the optical cables 105 and 105 '.
수광센서(106)는 전달된 빛을 전기적 신호로 바꾸어 와이어(107)를 통하여 마이콤에 전달하여 테이프(101)의 초기나 말기임을 감지토록 하였다.The light receiving sensor 106 converts the transmitted light into an electrical signal and transmits the light to the microcomputer through the wire 107 to detect the beginning or the end of the tape 101.
이때, 광케이블(105)과 광케이블(105')의 빛을 구별하기 위해서 광케이블(105)과 광케이블(105')의 광투과율을 다르게 구성함으로써 감지되는 광량의 차이에 따른 전압의 차이를 통해 어느측에서 또는 양측에서 동시에 빛이 통과되었는지를 구별 감지할 수 있다.At this time, by differentiating the optical transmittance of the optical cable 105 and the optical cable 105 'in order to distinguish the light of the optical cable 105 and the optical cable 105' on which side through the voltage difference according to the difference in the amount of light detected Alternatively, both sides can detect whether light has passed simultaneously.
예를들면 제6도에서 처럼 광케이블(105)을 통해 전달된 광량이 Ls라고 하면 이것에 비례하는 Vs=CLs가 감지되는 것이다. 여기서 C는 수광센서(106)의 광량과 전압의 비례상수이다.For example, as shown in FIG. 6, if the amount of light transmitted through the optical cable 105 is Ls, Vs = CLs proportional to this is sensed. Where C is the proportional constant of the light quantity and voltage of the light receiving sensor 106.
마찬가지로 광케이블(105')을 통해 전달된 광량이 Lt라 하면 전압은 Vt=CLt가 될 것이고, 광케이블(105)와 (105')이 동시에 량이 전달된다면 그 광량은 Ls+Lt가 되고 따라서 전압은 Vs+Vt가 될 것이다.Similarly, if the quantity of light transmitted through the optical cable 105 'is Lt, the voltage will be Vt = CLt. If the quantity of the optical cable 105 and 105' are simultaneously delivered, the quantity of light will be Ls + Lt and thus the voltage is Vs. Will be + Vt.
이렇게 해서 1개의 수광센서(106)를 통해 광케이블(105)(105') 양측의 구별감지가 가능하다.In this way, it is possible to detect the discrimination of both sides of the optical cables 105 and 105 'through one light receiving sensor 106.
이와 같은 본 고안은 수광센서의 설치장소에 대한 제약을 받지 않으므로 인하여 설계상의 자유도를 높일 수 있기 때문에 보다 더 콤팩트한 설계가 가능하다.Since the present invention is not restricted by the installation location of the light receiving sensor, the design degree of freedom can be increased, so that a more compact design is possible.
그리고 수광센서를 2개에서 1개로 줄일 수 있기 때문에 원가를 줄이는데 기여하며 설계 및 제품의 고장요인을 감소시킬 수 있는 고안이다.In addition, since the light receiving sensor can be reduced from two to one, it contributes to reducing the cost and reduces the design and product failure factors.
