Description of drawings
Fig. 1: the structural representation of yarn storage device of the present invention.
Fig. 2: the present invention does not have the structural representation of yarn storage device of the line-transmitting wheel of assembling.
The specific embodiment
The present invention is done with Fig. 2 below in conjunction with accompanying drawing 1 and to further describe.
Yarn storage device as depicted in figs. 1 and 2; Comprise motor, housing 1 and be installed in photoelectric sensor 2, main shaft, shading sleeve 6 and the line-transmitting wheel 3 on the housing 1, yarn ring 5 and tension ring 4 are pressed in socket on the line-transmitting wheel 3; Press yarn ring 5 to make yarn, speed and tension force when yarn is failed in tension ring 4 controls to downslide.Main shaft is in the circle centre position of line-transmitting wheel 3, and motor drives line-transmitting wheel 3 through main shaft and rotates, and photoelectric sensor 2 is installed on the housing 1 and the position is in the outside of line-transmitting wheel 3.
Shading sleeve 6 is enclosed within and prevents on the main shaft that it is reflective.Line-transmitting wheel 3 is provided with metal spoke 31 regularly arranged and that width is identical, is provided with the identical gap of width 32 between the adjacent metal spoke 31, and metal spoke 31 is identical with the width in gap 32.Photoelectric sensor 2 comprises two groups of photoelectric tubes at least, 32 places, gap on the metal spoke 31 on the corresponding line-transmitting wheel 3 of at least one group of photoelectric tube wherein, at least one group of corresponding line-transmitting wheel 3 of photoelectric tube.Shading sleeve 6 is round plastic shading sleeves, and round plastic shading sleeve and line-transmitting wheel 3 are center of circle concentric arrangement with the main shaft, and the round plastic shading sleeve is connected as a single entity with pressing yarn ring 5.The distance of all photoelectric tubes to shading sleeve 6 lateral walls is identical, and the distance of all photoelectric tubes to metal spoke 31 lateral walls is identical, has guaranteed that promptly the time of reception of all photoelectric tubes in the gap 32 on the corresponding line-transmitting wheel 3 is identical.At least one group of photoelectric tube transmits to metal spoke 31, and 31 reflections of metal spoke produce a reflection strong and weak signals.At least one group of photoelectric tube transmits to 32 places, gap, and shading sleeve 6 reflections produce a reflection strong and weak signals, through the difference generation control signal control rotating speed of motor of two reflection strong and weak signals.Also can further confirm into amount of thread, and the motion mode of the control of the reflected signal through photoelectric sensor 2 motor, promptly start shooting and shut down through two reflection strong and weak signals.
The method of line-transmitting wheel motion state comprises the steps: that the transmitter on (1) all photoelectric tubes is luminous on the control yarn storage device; Wherein at least one group of light process metal spoke 31 reflections that transmitter sends, corresponding receiving tube receives the reflection strong and weak signals that metal spoke 31 reflects; Wherein the light that sends of at least one group of transmitter gets into 32 places, gap on the line-transmitting wheel 3, and its corresponding receiving tube receives the reflection strong and weak signals that the plastics shading sleeve reflects; (2) the reflection strong and weak signals that reflection strong and weak signals that metal spoke 31 is reflected and plastics shading sleeve reflect is compared, and produces a difference; (3) can calculate current amount of thread through difference; And calculate motor speed according to the yarn tension that advances that current amount of thread and needs reach; The variation of difference forms a variable signal after control chip calculates; Silicon controlled conducting angle and time are controlled rotating speed of motor with this in the variable signal control circuit.
When work, along with the rotation of line-transmitting wheel 3, the yarn on the line-transmitting wheel 3 increases, and the amplitude of input reduces, and explains that into yarn speed lets motor speed reduce greater than yarn speed this moment.When advancing yarn speed and be lower than yarn speed, the amplitude of input increases, and control motor and rev up this moment, and storage yarn speed strengthens.This a reference value changes according to the difference of yarn; For example when sending white yarn, constant defeated yarn speed and tension value during the defeated yarn of corresponding line-transmitting wheel 3, its signal voltage is 2V; Storage during yarn when signal voltage maintenance present speed during for 2V; Control motor reduction of speed when hanging down with 2V, the control motor quickens when being higher than 2V, and adjusts motor speed accordingly through the scope of difference variation.
In addition; At least one group of photoelectric tube transmits to metal spoke 31; Metal spoke 31 reflection produces reflection strong and weak signals and signal reflection interval, and at least one group of photoelectric tube transmits to 32 places, gap, shading sleeve 6 reflections produce one reflect strong and weak signals and reflection interval signal.The difference of signal also produces control signal control rotating speed of motor through reflection interval.Because begin there is a time to full yarn from advancing yarn; Also can judge the speed of passing through of yarn through the length of computing time, when from the high level to the low level time, increasing, prove that rotating speed is slow excessively; The control motor revs up; If high level reduces to low level time, prove excessive velocities, the control motor reduces rotating speed.Control the output speed of motor according to top 2 kinds of method synthesis, thereby reach a kind of state of stable output.
