Description
Technical field:
The present invention relates to the digital synchronous dynamical system of a kind of jacquard and water jet looms.
Background technology:
On loom, during the fabric of a decorative pattern of weaving, need with jacquard as shedding mechanism.Its main feature is in the weaving process, can control the lifting of single heald, but also available excellent cutter to make a slice heald do elevating movement.The jacquard shedding mechanism, all formed by three mechanisms:
1, transmission mechanism: generally by space crank quadric chain transmission.Also useful vertical shaft type gear drive, driving types such as chain transmission.
2, shedding mechanism: by girff, griffe and institute such as lifting-hook forms.
3, decorative pattern controlling organization: formed by card, cylindrical fireworks and eedles.
Traditional transmission mechanism, chief component: loom master motor, loom driving belt, vertical shaft, jacquard main shaft, uni-drive gear box, clutch, main shaft shaft joint.Loom master motor-driven loom main shaft, loom main shaft is by jacquard main shaft, uni-drive gear box, clutch, main shaft shaft joint transmission jacquard main shaft.Usually the gearratio of loom main shaft and jacquard main shaft is 1: 2,1: 3,1: 4.When running well, must keep strict gearratio relation, guarantee cooperatively interacting of wefting insertion and harness motion, to realize staplings parking back full-jacquard mechanism and loom throw-out-of clutch simultaneously, and to seek the running of independently moveing backward of the electronic function of latitude, realize the automatic latitude seeking function, and then be connected to original position automatically with loom.Its various mechanism form (as power transmission shaft, chain, band etc. synchronously) that is in transmission connection.Above transmission mechanism is a machine driving, manufacturing technique is comparatively complicated, particularly when seeking latitude, loom needs to cut off active force by clutch, inconvenient operation, therefore utilize servomotor to make the jacquard active force, the gearratio that the main shaft of jacquard and the main shaft of water jet looms rotate can pass through program setting, and operation control is comparatively simple, makes both well to cooperate.
Summary of the invention:
The digital synchronous dynamical system that the purpose of this invention is to provide a kind of jacquard and water jet looms, it can make the main shaft of jacquard and the rotating ratio basically identical of water jet looms main shaft, in the error 1.03% each other.
Technology solution of the present invention is as follows:
The digital synchronous dynamical system of jacquard and water jet looms, comprise a jacquard, one water jet looms, one drives servomotor and motor that drives described water jet looms rotation that described jacquard rotates, between described jacquard and the water jet looms heald is arranged, described servomotor is connected with servo control system by lead, also be connected with a loom control system on this servo control system, coaxially in the end of jacquard main shaft be fixed with one second encoder, this second encoder is connected with servo control system, coaxial one first encoder, this first encoder and servo control system of being fixed with in the end of water jet looms main shaft, loom control system connects.
The digital synchronous dynamical system of described jacquard and water jet looms, the axial line of the water jet looms main shaft and first encoder roughly overlaps; The axial line of the jacquard main shaft and second encoder roughly overlaps.
The digital synchronous dynamical system of described jacquard and water jet looms, described water jet looms main shaft is connected with described first encoder by shaft coupling, and described jacquard weave main shaft is connected with described second encoder by shaft coupling.
Beneficial effect of the present invention is:
Utilize encoder to monitor jacquard main shaft, water jet looms main shaft, control drives the rotating speed of the servomotor of jacquard main shaft rotation then, realizes the synchronous rotation of jacquard main shaft, water jet looms main shaft.
Description of drawings:
The present invention is described further below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
The following stated is preferred embodiment of the present invention only, is not that scope of the present invention is limited.
Embodiment; See accompanying drawing 1, comprise a jacquard 1, one water jet looms 2, heald 3 is arranged between jacquard and water jet looms, be used for weft yarn being delivered to jacquard from water jet looms, jacquard utilizes these weft yarns to join with warp knit to go out various different colours decorative patterns again, jacquard main shaft 101 rotates by servomotor 4 controls, motor gear 5 is arranged on the servomotor, be fixed with driven gear 6 on the jacquard main shaft, the reduction gearing 7 that is used for lowering the jacquard speed of mainshaft is arranged between motor gear and driven gear, one of deceleration by reduction gearing is the impact when reducing servomotor and start, and also having is exactly to make the rotating speed that passes over from motor gear can be reduced in the scope of suitable jacquard main shaft work; Servomotor is connected with servo control system 8 by lead, control the work of servomotor by this servo control system, be fixed with driven pulley 9 on the water jet looms main shaft 201, this driven pulley is connected with driving pulley 11 on the motor 10 by belt, rotate by this motor drives water jet looms main shaft, coaxial one first encoder 12 that is fixed with in the end of water jet looms main shaft, the axial line of the water jet looms main shaft and first encoder roughly overlaps, this first encoder servo control system simultaneously, loom control system 19 connects through lead, loom control system also is connected with servo control system simultaneously, this first encoder body can be rack-mount, by support it is played the effect of support, best mode is that first encoder is connected with the water jet looms main shaft by shaft coupling 13, can play the effect of buffering.In this simultaneously, the end of jacquard main shaft is also coaxial to be fixed with one second encoder 14, the axial line of the jacquard main shaft and second encoder roughly overlaps, second encoder is connected through lead with servo control system, the second encoder body can be rack-mount, by support it played the effect of support, and best mode is that second encoder is connected with the water jet looms main shaft by shaft coupling 15, can play the effect of buffering, also be convenient to install.On servo control system, also be connected with one and combine flat switch 16, this switch is to need the harness eye of all healds must be at same horizontal level, just can control servo electrical machinery system by combining flat switch, be connected with a preparation button 17 in addition on the loom control system, be used for when opening, detect loom control system, whether servo control system is normal, can work, if normally then allow both be in starting state, preparation, control the startup of jacquard and loom then by start button 18, first encoder that on the water jet looms main shaft, is equipped with, be used for monitoring its speed of mainshaft, and 360 ° of positions of circumference, second encoder on the same jacquard main shaft, also be used for monitoring the jacquard speed of mainshaft, and 360 ° of positions of circumference, encoder on the water jet looms main shaft feeds back to loom control system with the data that obtain, by the current water jet looms spindle operation of loom notifications servo control system situation, encoder on the jacquard main shaft feeds back to servo control system with data, servo control system is learnt current jacquard spindle operation situation, contrast by these two data, finally control the rotating speed of servomotor by servo control system, make the synchronization of jacquard main shaft and water jet looms main shaft, in general the error of two main shafts is controlled within 1.03%.
