Referring to fig. 1, in an embodiment of the present invention, a sizing machine 100 is used to size a yarn 200 after spinning a fiber into the yarn 200, so as to improve the strength of the yarn 200, reduce hairiness and reduce the surface friction of the yarn 200. The sizing machine 100 includes a machine table 10, a plurality of sets of yarn guiding devices 30, and a yarn breakage detecting device 50. The yarn guiding devices 30 are sequentially disposed on the machine 10 for guiding the yarn 200 to advance to the downstream station. The yarn breakage detection device 50 is disposed between every two adjacent yarn guiding devices 30, and is used for detecting whether the yarn 200 located between the two adjacent yarn guiding devices 30 is broken.
The yarn guiding devices 30 are sequentially arranged along the advancing direction of the yarn 200, and each yarn guiding device 30 includes a shaft frame 31, a beam 33 rotatably connected to the shaft frame 31, and a rotation driving member (not shown). The shaft frame 31 is vertically provided on the machine 10 for providing a mounting base. The beam 33 is axially mounted on the carriage 31 and is rotatable relative to the carriage 31 by a rotary drive. Yarn 200 is wound around beam 33 and moves forward continuously with the rotation of beam 33. The axial direction of the beam 33 is perpendicular to the advancing direction of the yarn 200.
In this particular embodiment, each group of yarn guides 30 comprises four beams 33 rotatably mounted on a creel 31. Each two beams 33 of the four beams 33 are arranged in two rows, one above the other, on the creel 31, so that the four beams 33 are arranged in two rows, two courses, with the two beams 33 on the rows aligned and the two beams 33 on the courses aligned.
The yarn breakage detection device 50 includes a yarn suction mechanism 51 and a yarn breakage notification mechanism 53 (shown in fig. 3). The yarn suction mechanism 51 includes a yarn suction member 510 and a suction assembly 512 connected to the yarn suction member 510. The yarn sucking member 510 is disposed between every two adjacent yarn guiding devices 30 and located below the yarn 200, and is configured to suck the broken yarn 300 under the action of the yarn sucking power member 512 when the yarn 200 falls due to the broken yarn 300.
Referring to fig. 2, specifically, a yarn suction negative pressure cavity 5101 is formed in the yarn suction member 510, and a yarn suction port 5103 communicating with the yarn suction negative pressure cavity 5101 is provided on a surface of the yarn suction member 510 facing the yarn 200. The pumping assembly 512 includes a pumping power member 5121 and a pumping tube 5123 connected to the pumping power member 5121. The air suction pipe 5123 is connected between the air suction power element 5121 and the yarn suction negative pressure cavity 5101, and is used for forming a negative pressure environment in the yarn suction negative pressure cavity 5101, so that when the yarn 200 between two adjacent yarn guiding devices 30 is broken, the broken yarn 300 falls onto the yarn suction element 510 and can be sucked into the yarn suction negative pressure cavity 5101 through the yarn suction port 5103.
In an embodiment, the yarn sucking member 510 is disposed between two sets of yarn guiding devices 30 along a direction intersecting with the advancing direction of the yarn 200, and the yarn sucking port 5103 is opened on the yarn sucking member 510 along the longitudinal direction of the yarn sucking member 510 to be capable of sucking all broken yarns passing over the yarn sucking member 510.
In this embodiment, the yarn absorbing member 510 is in a cylindrical hollow tubular shape, and is disposed between every two adjacent yarn guiding devices 30 along the direction parallel to the beam 33 (i.e., perpendicular to the advancing direction of the yarn 200). The yarn suction port 5103 penetrates through and is provided in the longitudinal direction of the yarn suction member 510 (i.e., the cross section of the yarn suction member 510 is in the shape of a circular arc with an opening facing the yarn 200), and faces all the yarns 200 passing over the yarn suction member 510. Meanwhile, the air suction power element 5121 is an exhaust fan and is used for forming a negative pressure environment in the yarn suction negative pressure cavity 5101. When the yarn 200 positioned between two adjacent yarn guiding devices 30 is broken, the broken yarn just falls into the yarn suction port 5103 under the action of gravity and is quickly sucked into the yarn suction negative pressure cavity 5101.
It should be understood that, in other embodiments, the direction and angle of the yarn sucking member 510 relative to the beam 33 may be determined according to the needs, which is not limited herein, but only needs to be implemented so that the yarn sucking member 510 can suck the broken yarn falling thereon.
Referring to fig. 3, a yarn breakage reminding mechanism 53 is disposed in the yarn suction negative pressure cavity 5101 and generates reminding information when yarn breakage is sucked to remind an operator. The yarn breakage reminding mechanism 53 includes a yarn breakage sensing member 530, a controller 532 connected to the yarn breakage sensing member 530, and a reminder 534. The broken yarn sensing member 530 is used for detecting whether the broken yarn 300 is sucked in by the yarn suction port 5103 and generating a broken yarn signal when the broken yarn 300 is sucked in. The controller 532 is configured to receive the yarn breakage signal and control the reminder 534 to generate a reminder signal to alert an operator.
In an embodiment, the broken yarn sensing member 530 is a photoelectric sensor mounted on the yarn suction port 5103, the emitting end and the receiving end of the photoelectric sensor are respectively disposed at two ends of the yarn suction port 5103 in the longitudinal direction, and the detection light emitted by the emitting end extends over the whole yarn suction port 5103, so that the broken yarn 300 can be detected when being sucked from the yarn suction port 5103. Meanwhile, the reminder 534 may be used to generate an audible reminder signal (e.g., beeping sound, alarm sound, etc.), and may also be used to generate a visual signal (e.g., red light, etc.).
It should be understood that the yarn breakage sensing member 530 can be other sensing structures for sensing the yarn breakage 300, such as a camera for capturing an image of the yarn suction port 5103; meanwhile, the reminder 534 can also be other reminding signals to remind operators, which are not limited herein.
In one embodiment, the sizing machine 100 further includes a display coupled to the controller 532 for displaying the detection result of each broken yarn detecting device 50. Specifically, the controller 532 is further configured to receive the yarn breakage signal and control the display to display the detection result of the yarn breakage detection device 50. The detection result includes the current state (i.e. continuous or broken) of the yarn 200 between every two adjacent groups of yarn guiding devices 30 and the broken position (i.e. the position of the yarn sucking mechanism 51) of the yarn 200.
The invention also provides the broken yarn detection device 50.
In the broken yarn detecting device 50 and the sizing machine 100, the broken yarn is sucked through the yarn sucking mechanism 51 so as to prevent the broken yarn 300 from winding around the normal yarn 200 on the beam 33; meanwhile, the inhaled broken yarn triggers the reminding mechanism 53, so that the reminding mechanism 53 sends out a reminding alarm to remind operators, and the automatic yarn-breaking reminding machine has an automatic detection function, saves human resources and improves the production efficiency and the production quality of sizing.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
