Description
Technical field
The utility model relates to a kind of textile machine, particularly relates to the electronic dobby mechanism on a kind of loom.
Background technology
Loom now what mostly adopt is electronic dobby, such as the Staubli2650 dobbies is at present in the world than one of advanced dobbies, it is the high-speed dobbies of a kind of high-performance, its heald lifting control mechanism is such: the shedding arm moves with eccentric disc, and dish type connecting rod kink is on eccentric disc, eccentric disc acts on driving-disc mutually by the control hook, and whether the shedding arm moves with eccentric disc and then controlled by selecting mechanism.Driving-disc is linked and packed on splined shaft with spline, and the rotating rule of splined shaft is determined by slide block mechanism.Swing arm swings up and down under the conjugate cam effect, and drive suction jib also moves up and down.The characteristics of motion of shedding arm is by the suction of electromagnet and do not inhale two kinds of different conditions controls.If electromagnet is inhaled, then inhaling jib withstands left comer shape bar and moves down, the clockwise direction of left comer shape bar is swung outward, then controlling has two kinds of possibilities between hook and the driving-disc: a) a last latitude heald frame does not promote, control is hooked in the left side, because the plush copper that the effect of spring will be controlled on the hook is pressed into driving-disc, makes eccentric disc and driving-disc as a Rigid Body in Rotation With, drives the shedding arm heald frame is moved up and down.B) a last latitude heald frame promotes, and control hook and forward the right to this moment, is subjected to the effect of right corner shape bar, back plush copper embeds the recess of driving-disc, right corner shape bar is because the plush copper that will control on the hook by the effect of spring ejects from the recess of driving-disc, and eccentric disc separates with driving-disc, heald frame maintenance lifting state.Electromagnet is not inhaled, and then inhales jib and withstands right corner shape bar and move down, and the clockwise direction of right corner shape bar is swung outward, then control have between hook and the driving-disc two kinds may.This structure is very complicated, and production cost is higher.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel loom electronic dobby, to remedy the deficiencies in the prior art, meets the needs of production.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of novel loom electronic dobby comprises electromagnet 6, the shedding sheet 1 that the lower end engages by stay cord 13,1 ', about each one, described stay cord 13 is walked around the top sheave of assembly pulley 10; Chain 92,2 ' drives the shedding sheet conjunction 3 be fixed on the shedding sheet 1,1 ' by fixed thereon griffe, 3 ' moves up and down, thereby drives 1, the 1 ' motion of shedding sheet, sprocket wheel 8 is two up and down, and described chain 9 is on sprocket wheel 8, and sprocket wheel 8 is fixed on the frame 15; The lower sheave stay cord of assembly pulley 10 links to each other with heald frame 11 on one side, and the other end is fixed on the frame 15; Assembly pulley 10 moves up and down by stay cord 13; Sprocket wheel 8 all is fixed on the frame 15 with effect piece 12; Reed 5 is fixed on the guide rod 7, and guide rod can move up and down along the guide hole on the effect piece 12; Hanging block 4,4 ' is fixed on the effect piece 12, and hanging block 4, a wedge angle of 4 ' are positioned at the groove of effect piece 12, can swing, and when shedding sheet during in the top, hanging block 4, the locating hole 14,14 ' of shedding sheet 1,1 ' can just in time be passed in 4 ' tip; Electromagnet 6 is fixed on the frame 15, acts on guide rod 7 by the push rod inside its, guide rod 7 is moved up and down, thereby reed 5 acts on hanging block 4, and 4 ' makes hanging block 4, and 4 ' swings.
As optimized technical scheme: described shedding sheet 1,1 ' is pressed close to mutually with chain 9, but does not contact.
Described 2, the 2 ' the right and left that is separately fixed at chain 9 of griffing when griffing 2,2 ' when moving up and down, can be hung mutually with shedding sheet conjunction 3,3 ' and close or separate.
The beneficial effects of the utility model are: the utility model adopts the swinging of motion control hanging block of electromagnet, blocks the locating hole of carrying vertical sheet in position, carries the position of vertical sheet with this meter control, entire mechanism simple in structure, and reliable in action, cost is low.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
With reference to accompanying drawing 1-3, a kind of novel loom electronic dobby comprises electromagnet 6, the shedding sheet 1,1 ' that the lower end engages by stay cord 13, about each one, described stay cord 13 is walked around the top sheave of assembly pulley 10; Chain 9 by fixed thereon griffe 2,2 ' drives the shedding sheet conjunction 3 that is fixed on the shedding sheet 1,1 ', and 3 ' moves up and down, thereby drive shedding sheet 1,1 ' motion, described 2, the 2 ' the right and left that is separately fixed at chain 9 of griffing, when griffing 2,2 ' when moving up and down, and it moves up and down by hanging incompatible drive mutually with shedding sheet conjunction 3,3 '.Sprocket wheel 8 is two up and down, and described chain 9 is on sprocket wheel 8, and sprocket wheel 8 is fixed on the frame 15, and described shedding sheet 1,1 ' is pressed close to mutually with chain 9, but does not contact; The lower sheave stay cord of assembly pulley 10 links to each other with heald frame 11 on one side, and the other end is fixed on the frame 15; Assembly pulley 10 moves up and down by stay cord 13; Sprocket wheel 8 all is fixed on the frame 15 with effect piece 12; Reed 5 is fixed on the guide rod 7, and guide rod can move up and down along the guide hole on the effect piece 12; Hanging block 4,4 ' is fixed on the effect piece 12, and hanging block 4, a wedge angle of 4 ' are positioned at the groove of effect piece 12, can swing, and when shedding sheet during in the top, hanging block 4, the locating hole 14,14 ' of shedding sheet 1,1 ' can just in time be passed in 4 ' tip; Electromagnet 6 is fixed on the frame 15, acts on guide rod 7 by the push rod inside its, guide rod 7 is moved up and down, thereby reed 5 acts on hanging block 4, and 4 ' makes hanging block 4, and 4 ' swings.
The utility model is like this action: the sprocket wheel 8 that back and forth rotates drives chains 9 and pumps, owing to griffe 2,2 ' to be fixed on the chain, griffes 2,2 ' also to pump thereupon.Griffe 2,2 ' to drive corresponding shedding sheet conjunction 3,3 ' and take exercises, shedding sheet conjunction 3,3 ' connects shedding sheet 1, and 1 ' moves up and down.When shedding sheet 1,1 ' 2,2 ' moves up in the process with griffing, by hanging block 4, in the time of 4 ', with hanging block 4,4 ' promotes to swing to the inboard, griffe then 2,2 ' to begin to descend, at this moment, if electromagnet 6 is not worked, then the shedding sheet 1, and 1 ' is not tangled, 2,2 ' move downward together with griffing, this moment, the top sheave of assembly pulley 10 came back rotation, pulley center and non-displacement, heald frame 11 remains on the lower floor position under deadweight, and then this sheet is combined and be in lower floor when next latitude; If electromagnet 6 work, downward actuating spring 5, corresponding reed pressurized outwards promotes hanging block 4,4 ' pins shedding sheet locating hole 14 or 14 ', will carry vertical sheet 1 or 1 ' and tangle, and griffes separately downwards, simultaneously because the reciprocating motion of chain, another shedding sheet is griffing to be raised under the effect accordingly when pinning a shedding sheet, and this moment, assembly pulley produced the center displacement, and then this sheet is combined and be in the upper strata when next latitude.The most novel part of entire mechanism is its reading part, utilizes the cooperation of electromagnet and hanging block deadweight, finishes whole process.
The utility model is not limited to the above-mentioned specific embodiment; no matter what does on its shape and structure changes; swinging of every motion control hanging block that utilizes electromagnet; block the locating hole of carrying vertical sheet in position, all fall in the protection domain of the present utility model with this electronic dobby mechanism that controls the position of carrying vertical sheet.
