Description

선재의 길이 계측장치{The length of the wire measuring device}TECHNICAL FIELD [0001] The present invention relates to a wire length measuring apparatus,

본 발명은 통신 또는 전력공급의 선로 등으로 사용되는 전선의 선재 길이를 측정하는 계측장치에 관한 것으로, 특히 선재의 길이를 정확하게 측정시킬 수 있는 길이 계측장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measuring apparatus for measuring the length of a wire of a wire used as a communication or power supply line, and more particularly to a length measuring apparatus capable of accurately measuring a length of a wire.

선재의 제조 또는 선재의 길이 측정이 요구되는 산업장에서의 계측장치는 현재까지 여러 가지가 개발되어 사용되고 있는데, 그러한 선재의 길이 계측장치는 회전각도ㆍ위치 이동량과 같은 아날로그 값을 디지털 값과 같이 취급할 수 있도록 코드화 전기신호로 출력하는 변환기인 엔코더를 이용한 것이 주로 많이 사용되고 있다.There have been many developments in measuring instruments in the industrial field that require the manufacture of wire rods or the measurement of wire rods length. Such length measuring devices of wire rods handle analogue values such as rotation angle and positional displacement as digital values An encoder, which is a converter for outputting a coded electric signal, is mainly used.

엔코더를 이용한 선재의 길이 계측장치는 도 1에서와 같이 기대(1)의 상하 측에 액추에이터(2)로 승강하는 가동롤(3)과 엔코더(4)가 동축상에 구비되는 고정롤(5)을 수직선상에 배치하고, 가동롤(3)과 고정롤(5) 사이에서 선재(L)를 구름접촉식으로 밀어내면서 엔코더(4)가 고정롤(5) 회전량의 변위를 측정하여 선재(L)의 길이를 측정하게 된다. 이때 고정롤(5)의 원주는 계측장치의 기준값이다.As shown in Fig. 1, the apparatus for measuring the length of a wire using an encoder includes a fixed roll 5 on which a movable roll 3 ascending and descending by an actuator 2 at upper and lower sides of a base 1 and an encoder 4 are coaxially arranged, The encoder 4 measures the displacement of the fixed roll 5 in the rolling contact manner while pushing the wire rod L in a rolling contact manner between the movable roll 3 and the fixed roll 5, L) is measured. At this time, the circumference of the stationary roll 5 is a reference value of the measuring device.

그런데 이러한 엔코더를 이용한 선재의 길이 측정장치에서 장치의 기준값인 고정롤(5)의 원주가 선재의 압송과정에서 필연적으로 발생하는 마찰 등으로 인한 마모현상으로 변위가 일어나는, 즉 고정롤(5)의 기준값 반지름(R1)이 상기에서 설명한 마모현상에 의한 변형 반지름(R2)으로 변위가 일어나 고정롤(5)의 원주가 변화되어 선재의 측정 길이가 실제 길이보다 적게 계측되는 등 선재의 길이 측정이 부 정확하고 따라서, 계측장치의 제품성이 저하되고 있는 것이다.However, in the apparatus for measuring the length of a wire using the encoder, the circumference of the fixed roll 5, which is a reference value of the apparatus, is displaced due to abrasion due to friction or the like inevitably generated during the feeding process of the wire rod. The length of the wire rod is measured in such a manner that the reference value radius R1 is displaced by the deformation radius R2 caused by the wear phenomenon described above and the circumference of the fixed roll 5 is changed so that the measured length of the wire rod is measured to be smaller than the actual length And therefore, the productivity of the measuring apparatus is deteriorating.

그리하여 근래에 와서는 측정장치의 기준값 변위 염려가 없고 길이 측정이 보다 안정되고 정확한 계측장치의 개발이 시급히 요구되고 있는 실정이다.Thus, there has been no concern about displacement of the reference value of the measuring device in recent years, and development of a more stable and accurate measuring device is urgently required.

본 발명은 상기에서와 같은 사정을 고려하여 이루어진 것으로, 그 목적은 무한궤도의 이송벨트로 선재 이송을 이루게함과 동시, 이송벨트의 위치 이동량으로 선재의 길이를 측정하게 함으로서, 선재의 길이 측정이 정확한 선재의 길이 계측장치를 제공하는 것이다.SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method of measuring a length of a wire rod by measuring a length of the wire rod by using a conveyance belt of an endless track, And to provide an apparatus for accurately measuring the length of a wire rod.
