Description
Technical field
Occur the production accidents such as short latitude the present invention relates to weft in jet looms, one kind during lathe generation Stoppage is automatic
Handle the device of useless weft yarn.
Background technology
Air-jet loom is weaved by processes such as wefting insertion, beatings in process of production.During wefting insertion, send out sometimes
The phenomenon of raw staplings or staplings, will Stoppage automatically when the bobbin feeler of lathe side detects abnormal.General jet
After loom Stoppage, broken and underproof weft yarn and turned back on by workman artificial removal.
The content of the invention
It is an object of the invention to provide one kind after Weft Stoppage of Air-jet Loom, automatically remove and break and underproof weft yarn
Device.
In order to achieve the above object, the technical scheme is that a kind of weft yarn during there is provided Weft Stoppage of Air-jet Loom
Removal device, it is characterised in that including the vertical shower nozzle positioned at main jet head obliquely downward, vertical shower nozzle produces gas vertically upward
Stream, weft yarn is blown upward in framework by charging aperture, provided with push rod horizontally moveable and with resetting-mechanism in framework, is pushed away
Gas channel is provided with bar, gas channel is communicated with inlet suction port, provided with hollow shaft in framework, air-flow by inlet suction port,
Gas channel sprays into hollow shaft, so that the conical nose position of push rod produces suction inwards, by the latitude in framework
Yarn part is drawn into hollow shaft, drive mechanism promote push rod move horizontally, after moving into place, the conical nose of push rod with it is hollow
Axle agrees with, and the weft yarn in part suction hollow shaft is clamped, after weft yarn is clamped, cut weft yarn in main jet head by scissors,
Motor drives hollow shaft to rotate by travelling gear, and hollow shaft drives push rod and clamped weft yarn to rotate together so that latitude
Yarn is wrapped on the conical nose of push rod with rotation, and drive mechanism is unclamped after push rod, and push rod resets in the presence of resetting-mechanism,
Meanwhile, the weft yarn being wrapped on push rod conical nose is blown into magazine by the air-flow blown out by push rod.
Preferably, the resetting-mechanism includes the adjustment spring located at the push rod afterbody.
Preferably, the gas channel is out in the through hole of the push rod center position.
Preferably, air-flow enters in the inlet suction port via solenoid valve control.
Preferably, the push rod is promoted to move horizontally by air pump.
Preferably, in addition to weft sensor, on the one hand weft sensor is used to judge whether the weft yarn is inhaled into
In hollow shaft, so that providing signal controls the drive mechanism action, on the other hand, after scissors cut weft yarn, for judging
Whether weft yarn described in weft yarn is all wrapped on the conical nose of push rod, so as to provide signal so that push rod blows out air-flow.
After the present invention, it can realize and carry out the crawl of unqualified weft yarn during Weft Stoppage of Air-jet Loom automatically with going
Remove, reduce the workload of workman, reduce the labour cost of enterprise, improve the quality of production and efficiency of product.
Brief description of the drawings
Fig. 1 is structure schematic diagram of the invention；
Fig. 2 is hollow shaft and push rod sketch.
Embodiment
To become apparent the present invention, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.It should be understood that
These embodiments are only illustrative of the invention and is not intended to limit the scope of the invention.In addition, it is to be understood that reading the present invention
After the content of instruction, those skilled in the art can make various changes or modifications to the present invention, and these equivalent form of values equally fall
In the application appended claims limited range.
As shown in figure 1, the present invention provide a kind of Weft Stoppage of Air-jet Loom when weft yarn removal device include into magazine
1st, travelling gear 2, hollow shaft 3, the framework 4 with charging aperture, adjustment spring 5, air pump 6, main jet first 7, vertical shower nozzle 8, scissors
9th, push rod 10, inlet suction port 11, weft sensor 12.
When Stoppage occurs for air-jet loom, i.e., when Weft Detector on Air-jet Loom detects weft yarn generation exception, vertical spray
First 8 start upward jet, while magnetic valve is opened, inlet suction port 11 starts air inlet.Now, weft yarn is vertically sprayed via charging aperture
First 8 blow in framework 4, the vicinity close to the head of push rod 10.And the air-flow of inlet suction port 11 by the hole of push rod 10 to hollow shaft 3
Middle injection, can produce a suction inwards in the conical nose position of push rod 10, the part of weft yarn is drawn into hollow shaft 3
In.
After weft sensor 12 judges that weft yarn is inhaled into.Air pump 6 promotes push rod 10, the conical nose and hollow shaft of push rod 10
3 agree with, and weft yarn is clamped, and details are shown in Fig. 2.After weft yarn is clamped, scissors 9 are started working, and cut weft yarn at main jet first 7
It is disconnected.Now, closed electromagnetic valve, the no longer air inlet of inlet suction port 11.Meanwhile, motor drives hollow shaft 3 to rotate by travelling gear 2,
Rotated together by frictional force band logical push rod 10 and weft yarn, in the process, weft yarn is wrapped in the taper of push rod 10 with rotating
On head.
When weft sensor 12 can't detect weft yarn, illustrate that weft yarn has all been removed from lathe substantially, then by motor
Stalling.Now, magnetic valve is opened, and the air inlet again of inlet suction port 11, air pump 6 is closed.Push rod 10 is returned in the presence of adjustment spring 5
To original position, the weft yarn being originally compacted after push rod 10 and hollow shaft 3 are unclamped, immediately by hollow shaft 3 be blown into
In magazine 1.Magnetic valve is re-closing off, next, the device that the present invention is provided sends a signal to lathe master control system, represents weft yarn
Remove successfully, whole weft yarn removal process terminates, and lathe is turned back on.
The present invention uses above-mentioned design, and when Stoppage occurs for air-jet loom, underproof weft yarn can be caught automatically,
And cut and wound from lathe and extract, it should be noted that dry ace is that the device is carried, and is not jet
The confession yarn side scissors of loom.The invention crosses process automation by the unqualified weft yarn of artificial removal, improves the automation of lathe
Energy.To a certain extent, the amount of labour of workman is alleviated, the cost of enterprise is reduced, while improving the production of air-jet loom
Efficiency.
