The abnormal rear loom automatic stopping of loom wefting insertion, needs spinner by hand abnormal weft yarn to be removed, and the wefting insertion of again driving recovers the work of normally weaving.Wefting insertion anomalous effects weaving efficiency and product quality, increased workman's labour intensity and workload.So it is extremely urgent that weft yarn is removed automation, and control yarn and cut automatic shearing staplings yarn breakage.
[utility model content]
The purpose of this utility model is: after the abnormal generation of wefting insertion, the abnormal weft yarn of guiding loom Automatic-searching, abnormal weft yarn is removed, and introduce new weft yarn and recover loom normal operation, thereby avoid spinner by hand abnormal weft yarn to be removed, do not need manual intervention, reduce millworker's use amount, thereby improved textile enterprise's economic benefit.
For achieving the above object, the technical solution adopted in the utility model is:
The automatic staplings detaching device of one described in the utility model, comprise loom body, loom body is provided with some auxiliary jets, at the right-hand bobbin feeler that is provided with of low order end auxiliary jet, the left side of loom body is provided with weft accumulator and main burner, main burner below is provided with blowing up nozzle, the top of main burner is provided with yarn guide passage, in yarn guide passage, be provided with Yarn senser, yarn guide passage is connected with weft yarn batching apparatus with Yarn senser, the wherein other yarn feeding scissors, be provided with scissors blowing up nozzle adjacent with yarn feeding scissors of being provided with of main burner.
In the utility model: described weft yarn batching apparatus comprises support, fixed blade sheet, moving shear blade, vacuum suction reel and reel-motor, wherein fixed blade sheet is arranged on piston rod head and along vacuum suction spool axis direction moving linearly, moving shear blade is connected with shear blade guide rail on support, is taken and is moved moving shear blade simultaneously by cylinder.
In the utility model: the below of described fixed blade sheet is provided with refuse yarn case.
In the utility model: described reel-motor is connected with vacuum suction reel by rotating shaft.
Adopt after said structure, the utility model beneficial effect is: the utility model is simple in structure, reasonable in design, easy to use, thus avoid spinner by hand abnormal weft yarn to be removed by this device, the abnormal weft yarn of guiding loom Automatic-searching, abnormal weft yarn is removed, make that loom is more intelligent, automation, improved product percent of pass, quality product rate, reduced labor strength, reduce millworker's use amount, thereby improved textile enterprise's economic benefit.

[detailed description of the invention]
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples wherein and explanation are only used for explaining the utility model, but not as to restriction of the present utility model.
As shown in the figure, a kind of staplings detaching device automatically, comprise loom body, loom body is provided with some auxiliary jets 7, at the right-hand bobbin feeler 9 that is provided with of low order end auxiliary jet 7, the left side of loom body is provided with weft accumulator 1 and main burner 4, main burner 4 belows are provided with blowing up nozzle 5, the top of main burner 4 is provided with yarn guide passage 2, in yarn guide passage 2, be provided with Yarn senser 18, yarn guide passage 2 is connected with weft yarn batching apparatus 20 with Yarn senser 18, wherein the other yarn feeding scissors 3, be provided with scissors blowing up nozzle 6 adjacent with yarn feeding scissors 3 of being provided with of main burner 4.Described weft yarn batching apparatus 20 comprises support 17, fixed blade sheet 11, moving shear blade 14, vacuum suction reel 12 and reel-motor 16, wherein fixed blade sheet 11 is arranged on piston rod head and along vacuum suction reel 12 axis direction moving linearlies, moving shear blade 14 is connected with shear blade guide rail 13 on support 17, is taken and is moved moving shear blade 14 simultaneously by cylinder 15; The below of described fixed blade sheet 11 is provided with refuse yarn case 10; Described reel-motor 16 is connected with vacuum suction reel 12 by rotating shaft 19.
Wherein in accompanying drawing 1, in loom work, when bobbin feeler 9 detects when passing through without weft yarn, by the guiding of control program, scissors blowing up nozzle 6 blowing ups, loom reversing, automatic Proofreading fell is also opened fell, carries out wefting insertion action simultaneously, but now weft accumulator 1 does not carry out weft unwinding; In accompanying drawing 2, by weft accumulator 1, by easypro weft yarn solution 2 to 4 circles, main burner 4, auxiliary jet 7 spray wefting insertion, in wefting insertion, all the other bad weft yarns are separated from fell; In accompanying drawing 3, weft yarn blowing up nozzle 5 starts blowing up, and weft yarn 8 enters into yarn guide passage 2; In accompanying drawing 4, in the time of weft yarn 8 process yarn guide passage 2, the Yarn senser 18 at passage place detects weft yarn 8, then control system is sent the reel-motor 16 in instruction startup weft yarn batching apparatus 20, weft yarn 8 is controlled and is batched by the vacuum suction reel 12 of weft yarn batching apparatus 20, blowing up nozzle 5 blow offs, illustrate that weft yarn 8 absorption are reeled successfully after blowing up if Yarn senser 18 still can detect weft yarn 8.
By loom forward rotation, the weft yarn 8 on main burner 4, also by wefting insertion, is cut off by yarn feeding scissors 3 in the time that reed mouth advances.When Yarn senser 18 detects while passing through without weft yarn 8, weft yarn has batched, curling motor 16 stops, take moving shear blade 14 at compressed-air actuated effect lower cylinder 15 along the axis direction of vacuum suction reel 12 weft yarn of coiling 8 is pushed to fixed blade sheet 11 and cut off, the negative pressure that cut refuse yarn is produced by vacuum generator sucks in refuse yarn case 10 and finishes weft yarn demolishing process; Shear blade guide rail 13 is guide rails that moving-limiting shear blade 14 rotates.Carried out after bad weft yarn removes, loom reverses correction fell again, and fell is opened, and loom resets automatically and starts normal operation.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
