Abstract
The utility model discloses a broken stitch detection device for a weaving machine. The device comprises two infrared transmission devices, two infrared receiving devices, an audible alarm and a controller, wherein the infrared receiving devices are electrically connected with the controller; the controller detects signals transmitted by the infrared receiving devices; and when the infrared receiving devices receive infrared rays from the infrared transmission devices, the controller outputs a low level to the audible alarm, and after stitches are broken, the broken stitches block paths of the infrared rays, the infrared receiving devices cannot receive the infrared rays, simultaneously the controller outputs a high level to the audible alarm, and the audible alarm produces alarming sounds. One infrared transmission device and one infrared receiving device form a transmission and receiving pair, the infrared transmission device transmits the infrared rays, and correspondingly, the infrared receiving device receives the infrared rays; and therefore, the broken stitches can be accurately detected, and simultaneously, an alarm can be given. Furthermore, the weaving machine can be automatically stopped when the broken stitches are detected.
Description
Technical field
The utility model relates to a kind of broken thread detector, relates in particular to a kind of loom broken thread detector.
Background technology
Loom is again frame, loom, cotton spinning machine etc., and initial loom is that woven fabric machine is arranged, and the shuttle less loom machine technology is just set about research from 19th century, progressively push the international market from the fifties to.Since 20 century 70s, many novel shuttleless looms put goods on the market successively.Shuttleless loom has been obtained remarkable effect to the efficient of improving fabric and raising loom, be widely adopted in countries in the world, and accelerated the process that fabric manufacture equipment is transformed, the occupation rate of many developed countries shuttleless loom has reached about 80%, has occurred upgrading the main trend that substitutes fly-shuttle loom with shuttleless loom.But loom flower type Infinite Cyclic, change rapidly, machine 150,168 inches, plane No. E14, E18, the highest braiding speed 250 lines/minute.With the supporting sectional warper of warp knitting machine except the computer-controlled high speed warping machines is arranged, having developed has computer Real Time Monitoring high-speed warping machine, the warping machines that is exclusively used in crochet machine is also succeeded in developing.Manual straight-bar machines in the straight-bar machines develops into the knitting needle straight-bar machines that stops through independent development, can produce various shaped structures and three-dimensional once-forming fabric, automatically knit the neck straight-bar machines and adopted microcomputerized control, computer automatic flat knitting machine and computer full-automatic glove knitting machine are promoted the use of, and the Computerized flat knitting machine machine width of cloth can reach 60 inches.In the running of loom, knit line and rupture easily, after knitting line and disconnecting, if can not find at once, loom will continue operation so, and the cloth that point out this moment no matter pattern or thickness, its quality all descends, and this has also directly affected the quality of positive quick step.Cause production efficiency low, wasted human and material resources.
Summary of the invention
The purpose of this utility model provide a kind of can the real time automatic detection loom loom broken thread detector of broken string.
For realizing above-mentioned technical purpose, the technical scheme that the utility model is taked is: a kind of loom broken thread detector is characterized in that: comprise two infrared launchers, two infrared receiving devices, voice guard and controllers; An infrared launcher and an infrared receiving device are a pair of emission acceptance group, and infrared launcher emission infrared ray is corresponding, the infrared receiving device receiving infrared-ray; Infrared receiving device is electrically connected with controller, and controller detects the signal that infrared receiving device transmits; When infrared receiving device receives the infrared ray of infrared launcher emission, the controller output low level is to voice guard, after knitting the line disconnection, the line of knitting that disconnects blocks ultrared route, infrared receiving device does not receive infrared ray, to voice guard, voice guard sounds the alarm with Time Controller output high level.Infrared launcher and infrared receiving device are prior art, can adopt infrared transmitter and infrared remote receiver on the existing market.Controller and voice guard also are prior art, and its middle controller can adopt PLC.
As the further improved technical scheme of the utility model, also comprise the autostop drive unit that is electrically connected with controller, when controller output high level, the autostop drive unit disconnects the power supply of loom.The autostop drive unit adopts the conventional design of this area.
It is a pair of emission acceptance group that the utility model adopts an infrared launcher and an infrared receiving device, and infrared launcher emission infrared ray is corresponding, the infrared receiving device receiving infrared-ray; Therefore the utility model can accurately detect the broken string of loom, same alarm.Further, the utility model can also when detecting broken string, make the loom autostop.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
The specific embodiment
Embodiment 1
Referring to Fig. 1, this loom broken thread detector comprises two infrared launchers 3, two infrared receiving devices 2, voice guard 4 and controllers 1; An infrared launcher 3 and an infrared receiving device 2 are a pair of emission reception group, and infrared launcher 3 emission infrared rays are corresponding, infrared receiving device 2 receiving infrared-rays; Infrared receiving device 2 is electrically connected with controller 1, and controller 1 detects the signal that infrared receiving device 2 transmits; When infrared receiving device 2 receives the infrared ray of infrared launcher 3 emissions, controller 1 output low level is to voice guard 4, after knitting the line disconnection, the line of knitting that disconnects blocks ultrared route, infrared receiving device 2 does not receive infrared ray simultaneously, to voice guard 4, voice guard 4 sounds the alarm with Time Controller 1 output high level.Also comprise the autostop drive unit that is electrically connected with controller 1, when controller 1 output high level, the autostop drive unit disconnects the power supply of loom.
