Abstract
The flexible rapier loom with gripper band provided by the utility model is to convey the gripper band by rope or belt pulley to do the repeat motion. The rope pulley or the flat belt pulley fixed on the batten sley can be made into the cam pulley or designed according to the motion principles of different sley wave and the rapier head to fit different requirements. The structure is very simple and the rest parts keep the original mechanism and machine frame of the shuttle loom basically and seldom change so the utility model is helpful for the improvement of the shuttle loom.
Description
The utility model relates to and transform fly-shuttle loom as flexible rapier loom, it is characterized in that coming with rope sheave or flat tyre wheel the sword belt reciprocating motion of this loom of transmission, replaces the shuttle of traditional usefulness, to finish the wefting insertion action of loom.
At present domestic weaving produced main still the use long traditional fly-shuttle loom is arranged, and be large in number and widely distributed, but its productivity ratio is low, and noise is serious, and machine material consumption is many, is difficult to continue the future of development.Can expect, certainly will be replaced by shuttleless loom.And among various shuttleless looms, comparatively speaking, Rapier looms is big rising.
On Shanghai ITMA in 1986, Italy Cincla company has put on display a kind of CTR flexible rapier loom of being transformed by RVEFT-C type fly-shuttle loom, its sword belt brings transmission with profile of tooth, have five belt wheels, as shown in Figure 1 (Fig. 1 is the schematic diagram of this CTR type transmission sword belt).Wherein take turns 1 and wheel 5 be fixed on the frame wallboard, take turns 2,3 and 4 and all be fixed on the slay, with slay 6 swings.Cog belt surrounds on these five belt wheels, and it wears method as shown in Figure 1.Because belt wheel 1 and 5 maintains static, so when slay 6 swings, belt wheel 2,3 and 4 is with regard to the swing of all following slay and do forward and reverse gyration, should forward and reverse rotation transmit out by taking turns 3 again, biography is to flexible rapier (being sword belt), makes the sword head reciprocating and finish the wefting insertion action of loom.The problem that this kind of drive exists is, this cog belt is worked under the strong Frotteurism of high-tension all the time, and working life is very short, and at present domesticly yet do not have this cog belt production and supply, so be difficult to promote the use of.
Domestic 1511,1515 fly-shuttle looms are transform as the patent application of flexible rapier loom, its rapier transmission mechanism is made up of the crank rack-and-pinion at present.The 1515K fly-shuttle loom is transform as flexible rapier loom, and its rapier transmission mechanism then is made up of wefting insertion crank, wefting insertion short connecting rod, dihedral bar and tooth bar.
The utility model is primarily aimed at CTR flexible rapier loom shown in Figure 1, proposes to use rope or Belt Drive sword belt instead without cog belt, can increase the service life, and supplies also no problem, and can reduce wheel number, simplified structure.
Fig. 1 is the schematic diagram of CTR type transmission sword belt;
Fig. 2 is the schematic diagram by face of cylinder rope sheave or flat tyre wheel transmission sword belt;
Fig. 3 is the schematic diagram by the rope sheave of cam contour surface or flat tyre wheel transmission sword belt.
Now in conjunction with Fig. 2 and Fig. 3 the utility model is described in detail below.
Rope sheave or flat tyre wheel can be made cylindrical wheel face, as shown in Figure 2; Rope sheave or flat tyre wheel also can be made cam contour surface, as shown in Figure 3.Its axle center is fixed on the slay 2, with the slay swing, uses two ropes (steel wire rope or nylon rope etc.) or two reinforced flat rubber beltings (strengthening with steel wire or nylon yarn rope), 3 and 4 front and back to drag respectively.An end of 3 is cemented in frame the place ahead, and an end of 4 is cemented on the frame rear leaf spring 5, and 3 and 4 the other end then all is cemented on this rope sheave or the flat tyre wheel.Along with the swing of slay, this rope sheave or flat tyre wheel are done forward and reverse rotation with regard to corresponding, then and should forward and reverse rotation pass to sword belt wheel 6, make that sword belt is reciprocating to move with the wefting insertion of finishing loom.
Because rope or flat rubber belting are fore-and-aft directions along loom to the transmission of wheel, coming the transmission sword belt reciprocating with sword belt wheel 6 then is left and right directions along loom, so need bevel-gear sett (or helical gear) Z
1And Z
2Change 90 ° of directions.As shown in Figure 2.Gear Z
1Be packed on the same axle with rope sheave or flat tyre wheel, and gear Z
2Then be packed on another axle with sword belt wheel 6, the bearing block of these two axles then all is packed on the slay, with the slay swing.
When Fig. 2 or position shown in Figure 3, behind machine, will bear pulling force this moment by rope that is cemented in frame the place ahead or flat rubber belting to slay by the machine forward swing, force rope sheave or flat rubber belting crop rotation along the clockwise revolution, by gear Z
1And Z
2Make the revolution of sword belt wheel, finish and send the sword action; Otherwise, when after slay is by machine, being flapped toward before the machine, then bear pulling force by rope that is cemented in the frame rear or flat rubber belting, force the revolution of this rope sheave or flat rubber belting crop rotation contra solem, the sword belt wheel is reversed, move back the sword action to finish.
Because an end of rope or belt is cemented on the wheel face of rope sheave or flat tyre wheel, disobey frictionally and come transmission, so need not use cog belt, also not necessarily need use a lot of belt wheels in order to increase cornerite, therefore can simplify machine driving greatly, the service life of rope or belt is long, and supply also is out of question.In addition, the cylindrical surface that the wheel face of this rope sheave or flat tyre wheel was both commonly used also can be designed to cam contour surface as shown in Figure 3, to adapt to the variation of the sword belt characteristics of motion, further slow down sword belt in the movement velocity at its traverse two ends, and control the time of its sword head turnover shed open.This takes turns and also can be designed as the conjugate cam that fuses to alleviate the pulling force that rope band is born, and rear one end with rope band is cemented on the strong leaf spring at frame rear again, can reduce the required precision that this cam is made greatly.
The utility model is simple in structure, other as frame wallboard, opening, beat up, the warp let-off, the original structure that mechanism all can keep traditional fly-shuttle loom such as batch, therefore seldom change is particularly conducive to the retrofit work that existing fly-shuttle loom is transform as flexible rapier loom.
As being example with 1515 looms, the diameter of getting rope sheave or flat tyre wheel is 60mm, and the reciprocating traverse of slay at this place is 150mm, and the rotating angle that then can get rope sheave or flat tyre wheel is:
150/(60 π) * 2 π=5 radian ≈ is 290 °
As to get the gear number of teeth be Z
1=30
T, Z
2=18
T, getting the sword belt wheel diameter is 250mm, the reciprocating traverse that then can get the sword head is:
150/(60 π) * this traverse of 30/18 * 250 π=1042mm can be fit to the wealthy width of cloth requirement of 1515 looms.
Claims (3)
1, a kind of by sword belt wefting insertion, connecting rod beat up, opening, the warp let-off and the flexible rapier loom that mechanism forms such as batch, it is characterized in that coming the motion of transmission sword belt with the rope sheave or the flat tyre wheel that are contained on the slay.
2, flexible rapier loom according to claim 1 is characterized in that this rope sheave or flat tyre wheel can have cylindrical surface, also can be designed to cam contour surface.
3, according to claim 1,2 described flexible rapier looms, it is characterized in that their end being cemented on flat tyre wheel or the rope sheave with two flat rubber beltings or rope, the other end then is cemented in respectively on frame the place ahead and the rear leaf spring.
