Abstract
The utility model provides an automatic shed finding device which can be used for automatically finding a shed so as to weave a multilayer fabric, and a weaving machine with the automatic shed finding device. The automatic shed finding device provided by the utility model comprises a drive control unit, a servo motor, a speed reducing device, a ball screw unit and a rapier transmission device, wherein the servo motor is connected with the drive control unit, the speed reducing device is connected with an output shaft of the servo motor, the ball screw unit is connected with an output shaft of the speed reducing device, and the rapier transmission device is fixed with a screw nut of the ball screw unit. The automatic shed finding device and the weaving machine with the automatic shed finding device have the advantages that the automatic shed finding device provided by the utility model can be used for automatically finding the shed, so that the multilayer fabric weaving machine provided by the utility model can achieve the process that the multilayer fabric is woven through layer-by-layer automatic weft insertion; the multilayer fabric can be woven by adopting a steel reed with lower height; a shedding device of the weaving machine can be simplified; and the continuous and automatic weaving of multilayer-corner-linking and three-dimensional fabrics becomes possible.
Description
Technical field
The utility model relates to a kind of weft inserting apparatus and loom thereof, especially a kind of automatic searching shed opening device and loom thereof.
Background technology
Particularly in field of compound material, some fabric can reach tens layers at industrial cloth, and fabric thickness reaches tens millimeters (seeing accompanying drawing 1), and the shape of shed open and high and low position are along with the difference of fabric layers can constantly change (seeing accompanying drawing 2).Present most of Rapier looms all is to be used to weave woven; The loom of minority weaving multiple layer fabric adopts leaves several shed opens simultaneously; The corresponding one group of weft insertion rapier of each shed open; All arrow shafts all will be moved simultaneously during wefting insertion, and this method only is fit to the simple relatively fabric of the less institutional framework of the number of plies.If the number of plies is more, all shed opens simultaneously during opening between orlop warp thread and the superiors' warp thread spacing inevitable very big, reed just must increase thereupon, the intensity of reed can reduce along with increase highly, is unfavorable for beating up; When weaving complex textile, have the unintelligible phenomenon of opening and influence wefting insertion.At present also desirable without comparison weaving multiple layer (the maximum number of plies is 30 layers) angle joins the automatic loom of fabric, does not also have the weft insertion device that is suitable for.
The utility model content
The utility model provides a kind of automatic searching shed opening device and the loom thereof that can seek shed open weaving multiple layer fabric automatically; Join at the more multilayer angle of the number of plies or three dimensional fabric adopts one group of weft insertion rapier successively during wefting insertion; The weft insertion rapier high and low position adapts to the depth of shed lower position automatically to be changed, and makes loom operation automatically continuously.
Realize the automatic searching shed opening device of one of the utility model purpose; Comprise driving control unit, the servomotor that links to each other with said driving control unit; The deceleration device that links to each other with said servomotor output shaft; The ball screw unit that links to each other with the output shaft of said deceleration device is fixed with the arrow shaft transmission device with the feed screw nut of said ball screw unit.
Described automatic searching shed opening device also comprises the line slideway unit, and said line slideway unit comprises guide rail and slide block, and said slide block is fixed on the free end of the feed screw nut of said ball screw unit.
Realize two multiply cloth loom of the utility model purpose, comprise above-mentioned automatic searching shed opening device.
Described multiply cloth loom comprises two above-mentioned automatic searching shed opening devices, lays respectively at the and arranged on left and right sides of loom, realizes wefting insertion simultaneously.
The automatic searching shed opening device of the utility model and the beneficial effect of loom thereof are following:
The automatic searching shed opening device of the utility model can be sought shed open automatically, makes the multiply cloth loom of the utility model can realize the multiply cloth weaving process of automatic wefting insertion successively; Can adopt highly lower reed weaving multiple layer fabric; Can make the shedding motion of loom obtain simplifying; Multilayer angle couplet and three dimensional fabric are weaved continuously automatically become possibility.
Description of drawings
Fig. 1 joins the structural representation of fabric for the multilayer angle.
Fig. 2 is in the multiply cloth weaving process, and the shed open position changes sketch map with fabric layers.
Fig. 3 is the structural representation of the automatic searching shed opening device of the utility model.
The specific embodiment
As shown in Figure 3; The automatic searching shed opening device of the utility model; Comprise driving control unit 1, the servomotor 2 that links to each other with said driving control unit 1; The deceleration device 3 that links to each other with said servomotor 2 output shafts, the ball screw unit 4 that links to each other with the output shaft of said deceleration device 3 is fixed with arrow shaft transmission device 6 with the feed screw nut of said ball screw unit 4.
Described automatic searching shed opening device also comprises line slideway unit 5, and said line slideway unit 5 comprises guide rail and slide block, and said slide block is fixed on the free end of the feed screw nut of said ball screw unit 4.
The multiply cloth loom of the utility model comprises two above-mentioned automatic searching shed opening devices, lays respectively at the and arranged on left and right sides of loom, realizes wefting insertion simultaneously.
The operation principle of the automatic searching shed opening device of the utility model is following:
Like Fig. 2, shown in 3; Driving control unit 1 is according to the loom opening information of obtaining; High and low position when calculating the corresponding N layer of weft insertion rapier shed open wefting insertion drives the direction rotation given number of turns of servomotor 2 by expection according to result of calculation, and the rotation of servomotor 2 is slowed down through deceleration device 3; The output shaft of deceleration device 3 drives the ball-screw rotation, and ball-screw nut will drive slide block band in the line slideway unit 5 and wefting insertion gear unit 6 and move up or down along line slideway.The rising of wefting insertion unit or decline are by the decision that turns to of servomotor 2, and the traverse of at every turn going up and down can preestablish before start according to the thickness decision of wefting insertion radical and warp, weft yarn at every turn.When weaving process parameter changes, can set or revise through keyboard.
Claims (4)
1. seek shed opening device automatically for one kind; It is characterized in that: comprise driving control unit, the servomotor that links to each other with said driving control unit; The deceleration device that links to each other with said servomotor output shaft; The ball screw unit that links to each other with the output shaft of said deceleration device is fixed with the arrow shaft transmission device with the feed screw nut of said ball screw unit.
2. automatic searching shed opening device according to claim 1 is characterized in that: also comprise the line slideway unit, said line slideway unit comprises guide rail and slide block, and said slide block is fixed on the free end of the feed screw nut of said ball screw unit.
