The light sensors i 8 i, 丄 8 2 can be used to detect whether the yarn on the yarn storage wheel 18 is sufficient. When the light sensors 181 18 2 detect that the yarn is insufficient, an activation signal is output. The 9/17 201126038 electromagnetic coil 15 is turned on to excite it. The yarn can pass through the guide member of the yarn guiding member 1 1 2, 1 1 q τ τ, and is wound around the storage yarn 钤] only 1 1 5 to drive the yarn to store the yarn wheel 18 as shown in the figure The electromagnetic coil 15 energizes the value #16"5H drive disk 14 to be absorbing and engaging, whereby the engagement d is transmitted to the second transmission shaft 17 for rotating the yarn to the yarn storage wheel 18 The action of storing the yarn is performed in succession. As shown in the first figure and the second figure, when the electromagnetic coil η is powered off; the disk 1 side is pulled with the elastic element 1 4 ! and the passive disk: 'make the The drive plate 14 and the passive disk 6 maintain a certain amount of land, thereby separating the first drive shaft 3 and the second drive shaft j, from the 3° first drive shaft 13 to the second drive shaft In the embodiment, the yarn storage wheel 18 is provided with three light sensors 81, which are infrared emitters; There are three light sensors 18 2 corresponding to the outside of the yarn storage rim 8 , which are infrared receivers. The (infrared emitter) 181 can emit infrared rays and pass through the nails _1 . A gap between 8 3 is irradiated to the outside of the yarn storage rim 8 to receive infrared rays by the light sensors (infrared receivers) i 8 2, thereby judging whether or not the yarn on the yarn storage wheel 18 is sufficient. 1 to 3, the present invention further provides a yarn detecting method for the yarn storage device of the electromagnetic clutch 10/17 201126038, comprising the following steps: First, a yarn accumulator device 1' is provided. The utility model has a body 1 1 , an electromagnetic coil 15 disposed on the body 11 , a first transmission shaft 13 rotatably disposed on the body 11 , and a second transmission shaft 1 rotatably disposed on the body 11 7. One end of the first transmission shaft i 3 is connected to a driving plate 14, one end of the second transmission shaft 17 is connected to a passive disk 16. The passive disk 16 is disposed opposite to the driving plate 14, the first transmission shaft 3 and the second transmission The shafts 17 are spaced apart, and the second transmission shaft 丄7 is connected and connected. • A yarn storage wheel 18, the yarn storage wheel 18 has a plurality of storage nails 18 3 disposed at intervals, and light sensing is disposed on the inner side and the outer side of the yarn storage wheel 18, respectively. 18 1 and 18 2, the light sensors 181 and 18 2 include transmitting and receiving a light sensor; and then winding the yarn (not shown) around the outer edges of the storage nails 8 3; as shown in the fourth and fifth figures, D1, D2 and D3 respectively represent a set of light sensing benefits 181 and 1 8 2 The generated signal chain, each signal chain D ! _, D 2 and D 3 is composed of successive high signal gradations and low signal gradations, and the south 彳 阶 metric indicates the light sensor ( Infrared receiver) 1 8 2 receives the optical signal (infrared), low signal level means that the light sensor (infrared receiver) 18 2 does not receive the optical signal. When only part of the optical signal is yarn or storage nail 18 3 When the occlusion is broken, it indicates that the yarn is insufficient. At this time, the -start signal is output to turn on the electromagnetic coiler 5 to excite it, thereby engaging the driving disk 14 at the end of the first transmission shaft 13 and the passive disk at the end of the second transmission shaft 17 16. The rotational power of the first drive shaft 3 is transmitted to the second drive shaft 17 for rotation of the belt-yarn rim 8 so that the yarn is wound around the yarn storage wheel 18 for storage (filling) And when all receiving light sensors (infrared receivers) 182 are 11/17 201126038, no optical information is received. When it is indicated that there is too much yarn wound on the yarn storage wheel 28, the output-off signal is output to interrupt the excitation of the electromagnetic coil i5, and the driving disk 14 and the second transmission shaft 丄7_ at one end of the first transmission shaft 13 are separated. Passing the passive disk 16 to transfer the first drive shaft 丄3 to the second drive shaft 丄? The power of the spinning is interrupted, making the storage wheel! 8 Stop rotating to stop the yarn storage action. Please refer to the sixth picture, three sets of light sensors (infrared receivers) 8 2, as long as there is a set of light sensors (infrared receivers) 1 8 2 received optical signals (infrared), then the domain should be (infrared The receiver) 丄 8 2 enters the conduction state. At this time, the grounding is sent to the first input terminal (1) of the comparator muscle via the electrically induced light sensing II (infrared minus H) 182. The second input terminal (+) of the comparator U2A receives the threshold voltage Vth, and compares the calculated ground voltage Vg with the threshold voltage Vth, thereby outputting the start signal for starting the electromagnetic coil 15. Further, when all of the light sensors (infrared receivers) 82 have not received the optical signals, all of the light-sensing stomachs (infrared receivers) 1 8 2 are all turned off. At this time, a preset high voltage DC24V is sent to the first-input terminal (―) of $U2A. The comparator U2A compares and calculates the preset south voltage DC24V and the threshold voltage vth, and outputs the off signal to turn off the electromagnetic coil 15. The electromagnetic clutching yarn storage device of the invention can be applied to a computer jacquard machine with irregular yarn feeding, and does not need to provide a motor inside the yarn storage device, so that the body (4) is large and the manufacturing cost is increased. And the electromagnetic coil 1 5 consumes less power, less mechanical (four) (four) power saving effect. The passive disk 16 of the present invention is connected to the end of the second transmission shaft 17, and the driving disk 14 is connected to the end of the first transmission shaft 13, and the first transmission shaft 13 and the second transmission shaft 17 are opposite and spaced apart. Provided to form a two-stage 12/17 201126038 design, the second drive shaft does not need to be worn inside the first transmission shaft 13. Therefore, when the electromagnetic coil 15 is de-energized, the drive plate i 4 is separated 'the second There is no contact between the drive shaft" and the first drive shaft 3, so that the rotational power can be surely interrupted to ensure that the yarn storage wheel 18 stops rotating. = "The invention is provided with light sensing f181, 182 on the inner side and the outer side of the storage wheeler 8". The light sensors 181, 182 directly send the receiving signal, which can accurately detect the yarn on the storage yarn 18. So that the stocking =1 8 pays an appropriate amount of yarn, and the storage rim 8 does not need to change s and the 'simple structure' does not increase the manufacturing cost.
