Description
Technical field
The invention belongs to field of textiles, it relates to a kind of automatic weft insertion device that continuous weft is knitted tubing of introducing on rigid rapier weaving machine.
Background technology
The weaving of the thin close tubing of extra-high-speed both requires the weft yarn introduced continuous, requires the precision height of loom again.On the fly-shuttle loom,, can realize that the weft yarn of introducing is continuous, but the loom precision is low, can not carries out that thin extra-high-speed is close weaves by shuttle reciprocal wefting insertion in shed open.When rigid rapier weaving machine is weaved, after weft insertion system draws weft yarn, need weft yarn is cut off, so can not carry out tubing.
Summary of the invention
Technical problem to be solved by this invention provides and introduces the automatic weft insertion device that continuous weft is knitted tubing on a kind of rigid rapier weaving machine, this mechanism is on rigid rapier weaving machine, utilize rigid rapier to grip shuttle reciprocal wefting insertion in shed open, realize weaving automatically the close tubing of thin extra-high-speed.
Technical scheme of the present invention is as follows:
A kind of rigid rapier weaving machine of the present invention is introduced the mechanism of continuous weft, comprises grip device, receiving system, shuttle; Characteristics are: grip device is fixed on above the rigid rapier, is positioned at loom one side, and receiving system is made up of grip block and movable bayonet lock, and is positioned at the opposite side of loom;
Before the wefting insertion: the shuttle back is inserted in the grip device and is fixedlyed connected by frictional force with grip device, and grip device is fixed on above the rigid rapier;
When warp thread formed tubing lower floor shed open: rigid rapier stretched out, be with grip device and shuttle to pass shed open, shuttle is inserted the desired location in the grip block of receiving system, pin above the movable bayonet lock inserts the aperture at shuttle back, shuttle, movable bayonet lock and grip block are fixed together, and rigid rapier and grip device are got back to the wefting insertion front position from shed open;
When warp thread formed tubing upper strata shed open: rigid rapier stretched out, pass shed open and it is inserted into the back of the shuttle in the grip block that is clipped in receiving system with grip device, pin above the movable bayonet lock withdraws from from the aperture at shuttle back, rigid rapier retraction, the grip device on it rely on the frictional force band shuttle and turn back to the wefting insertion front position.
All have groove on grip device and the grip block, the shuttle back is provided with projection, and the projection at the groove of grip device and shuttle back is loose fit when inserting beginning, is tight fit inserting when finishing; The protruding loose fit at the groove of grip block and shuttle back;
Groove on grip device and the grip block is a T-slot, and the projection at shuttle back is that the groove on T shape projection or grip device and the grip block is a dovetail groove, and the projection at shuttle back is a dovetail tangs;
Grip device and grip block are made by rigid plastics or metal material; Pin above the movable bayonet lock is the circular metal bar, and flexible by cylinder or electromagnet control.
Advantage of the present invention and beneficial effect are:
1. realized on the rigid rapier weaving machine that the weft yarn of introducing is continuous;
2. can on high-precision rigid rapier weaving machine, realize the system of knitting automatically of tubing.
Description of drawings
Fig. 1 is the structural representation of original state of the present invention,
Fig. 2 to Fig. 4 is four kinds of working state schematic representations of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The present invention includes rigid rapier 8 that is fixed on loom 4 one sides and the grip device 7 that can hold shuttle 6, be fixed on the receiving system that loom 4 opposite sides also can be held shuttle 6.
Cooperation and movement relation between each parts of the present invention are as follows:
Initial position: rigid rapier 8 is held the right side that shuttle 6 is parked in loom 4 by grip device 7, prepares wefting insertion.Grip device 7 is fixed together with arrow shaft 8, and the back of shuttle 6 can be inserted in the grip device 7, (as shown in Figure 1) that the frictional force by 7 of shuttle 6 and grip devices is fixed together.
The first step: warp thread forms tubing lower floor shed open, and rigid rapier 8 stretches out, and grip device 7 and shuttle 6 are passed shed open (below the reed 3), and shuttle 6 is inserted the receiving system that is positioned at loom 4 lefts, simultaneously weft yarn 5 is introduced upward (descending) layer of tubing.Receiving system is made up of grip block 2 and movable bayonet lock 1.When shuttle 6 is inserted in the grip block 2 behind the desired location, pin 11 above the movable bayonet lock 1 inserts the aperture 61 at shuttle 6 backs, shuttle 6, movable bayonet lock 1 and grip block 2 are fixed together, rigid rapier 8 begins retraction then, shuttle 6 overcomes and the frictional force of 7 of grip devices and skid off grip device 7, rigid rapier 8 and grip device 7 are got back to initial position from shed open, and shuttle 6 is stayed loom 4 left sides (Fig. 2,3).
Second step: warp thread forms tubing upper strata shed open, rigid rapier 8 stretches out, grip device 7 is passed shed open and be inserted into the back that the left side is clipped in the shuttle 6 in the receiving system, pin 11 above the movable bayonet lock 1 withdraws from from the aperture 61 at shuttle 6 backs, then rigid rapier 8 begins retraction, the receiving system that grip device 7 on it relies on the frictional force band shuttle 6 disengaging looms 4 right sides turns back to initial position from shed open, the weft yarn 5 in the shuttle 6 is introduced upward (descending) layer (Fig. 4,1) of fabrics.
The grip device 7 among the present invention and the specific embodiment of grip block 2 are:
Embodiment 1: open T-slot on grip device 7 and the grip block 2, material is a rigid plastics.T shape projection is made at shuttle 6 backs.The T shape projection at the T-slot of grip device 7 and shuttle 6 backs is the loose fit relation when inserting beginning, is the tight fit relation inserting when finishing; The T shape projection at the T-slot of grip block 2 and shuttle 6 backs is loose fit relations.Pin 11 above the movable bayonet lock 1 is the circular metal bar, utilizes electromagnetic principle control flexible.
Embodiment 2: drive dovetail groove on grip device 7 and the grip block 2, material is a metal.Dovetail tangs is made at shuttle 6 backs.The dovetail tangs at the dovetail groove of grip device 7 and shuttle 6 backs is the loose fit relation when inserting beginning, is the tight fit relation inserting when finishing; The dovetail tangs at the dovetail groove of grip block 2 and shuttle 6 backs is loose fit relations.Pin 11 above the movable bayonet lock 1 is the circular metal bar, utilizes pneumatic principle control flexible.
