Description
Technical Field
The utility model relates to a yarn automatic stop device, in particular to a yarn break automatic stop device for detecting chenille finished yarns.
Background
With the updating of mechanical equipment of the chenille yarn, the improvement of raw material technology, the expansion of product range and the improvement of operation technology of a car stopper, the platform watching amount of the chenille car stopper is increased from the initial 20-30 ingots to the current 300-500 ingots, so that the self-stopping device of the chenille yarn is particularly important. Due to the increase of the number of the watching platforms of the yarn blocking workers, the yarn blocking workers are forced to have no time for processing yarn and processing broken ends spindle by spindle, so that a large amount of raw materials are wasted and the machine parts are abraded.
The self-stop mode of the broken chenille yarn is various:
the chenille automatic stop device is provided on the earliest chenille equipment, the principle is that a microswitch is arranged at the outlet of a channel of all raw materials of mechanical equipment, the microswitch is arranged after the raw material yarns have certain tension, the microswitch is closed, once any yarn is broken or used, the microswitch rebounds and opens to immediately send a signal to a control device, and a motor is stopped (as shown in figure 1). However, the maximum disadvantage is that the starting time is too long, and since each micro switch needs to be in a working state and each yarn needs to have a certain pressure, when the machine is started, a worker needs to hold down the button with a hand all the time and can release the button after each yarn has a certain tension, so that a lot of time is delayed, the operation is greatly influenced, and the micro switch is gradually removed by each user for use soon.
Another method is to achieve the purpose of self-stop of chenille broken ends by detecting raw materials (as shown in fig. 2), the principle is an electromagnetic rotating wheel mode, namely, an electromagnetic rotating wheel device is installed at the channel of each core wire and knitting wool, as long as the yarn is not broken, the electromagnetic rotating wheel always rotates, the machine keeps running, once any yarn is broken or used, the rotating wheel stops rotating, the wheel gives a stop signal to stop, but the method has two disadvantages: firstly, the middle of the rotating wheel often has flying leads to the rotating wheel being stuck and not rotating, thus causing error stop; and the second is that the core wire 2 occasionally runs out of the central groove of the roller-tab in the running process, so that the core wire 1 and the core wire 2 cannot be on one central wire, and the woolen yarn is missed to be clamped, but because the woolen yarns of the core wires are not broken, the spindle cannot be stopped, and the effect of automatic stop cannot be achieved.
Accordingly, there is a need for improvements in the art.

The head end of the inclined notch 13 starts from the edge of the limiting metal sheet 12 and extends inwards along the diagonal direction of the limiting metal sheet 12 until the tail end of the inclined notch 13 extends to the central position of the limiting metal sheet 12, and the chenille yarn passes through the tail end of the inclined notch 13 (the central position of the limiting metal sheet 12). The limiting metal sheet 12 is provided with a blocking protrusion 14 at the head end of the inclined notch 13, the length of the blocking protrusion 14 is about two thirds of the width of the inclined notch 13, and the blocking protrusion 14 is used for limiting the chenille yarn at the central position of the limiting metal sheet 12.
The limiting metal sheet 12 provides a contact point for the chenille yarn, and the inclined notch 13 formed in the limiting metal sheet limits the displacement of the chenille yarn to a certain degree, so that the chenille yarn is prevented from being directly contacted with the detection box 1, and the twist of the chenille yarn is prevented from being influenced.
The material of spacing sheetmetal 12 is aluminium oxide, because the high-speed pull motion is done to the chenille yarn under the drive of machine, even if spacing sheetmetal 12 of stainless steel or tungsten steel material, also can pull out the wire casing on spacing sheetmetal 12 for a long time, and the aluminium oxide material is hard and plasticity is strong, and the low price can effectively avoid the yarn wearing and tearing machine and accessory on every side, therefore spacing sheetmetal 12 adopts aluminium oxide.
The detection notch 11 monitors the on-off condition of the chenille yarn in real time through an optical device arranged in the detection box 1, and the optical device for detection is a photoelectric emitter 2 and a photoelectric receiver 3 which are used in a matched mode.

The opposite faces of the detection notch 11 are respectively provided with through holes matched with the installation of the photoelectric emitter 2 and the photoelectric receiver 3, and the Fresnel lens 4 covers the through holes of the detection notch 11 to prevent sundries from entering the detection box 1 along the through holes and protect the end faces of the photoelectric emitter 2 and the photoelectric receiver 3. The photoelectric emitter 2 emits a light beam set to the photoelectric receiver 3, the light beam set is irradiated on the chenille yarn after being focused by the Fresnel lens 4, and then the light beam set is received by a light sensing plate arranged on the photoelectric receiver 3.
The detection of the yarn of the chenille finished product by means of the photoemitter 2 and the photoreceiver 3 can be used, in everyday use, new problems can occur anyway, such as: in the production process of the circuit board, the infrared photoelectric emitter 2 and the photoelectric receiver 3 have certain deviation more or less, and signals of the infrared photoelectric emitter and the photoelectric receiver can be strong or weak, so that a set of Fresnel lens is additionally arranged between the photoelectric emitter 2 and the photoelectric receiver 3 according to the principle of the Fresnel lens, the emitted light can be well gathered (figure 4), and after the Fresnel lens is used, the strength of the emitted signals of the Fresnel lens is completely unified.
A yarn breakage automatic stop method for detecting chenille finished yarn comprises the following steps:
detecting whether the finished yarns have the fluff or not by an infrared detection device (a photoelectric emitter 2 and a photoelectric receiver 3); the machine is stopped when no pile is detected in the finished yarn.
A Fresnel lens 4 is arranged between the photoelectric emitter 2 and the photoelectric receiver 3; the fresnel lens 4 serves to collect the light beam emitted by the emitter head.
Finally, it is also noted that the above-mentioned lists merely illustrate a few specific embodiments of the utility model. It is obvious that the utility model is not limited to the above embodiments, but that many variations are possible.
