Abstract
The pneumatic jacquard device designed in the present invention consists of harness wire, harness-back springs and the harness wire lifting unit which drives warp yarn lifting. Said lifting unit is a pneumatic unit including cylinder and air supply, harness wires are connected with the pneumatic piston rod in cylinder, and cylinder is connected with air supply through air course pneumatically. Said harness wire in different position which lifts warp yarn in different position can be linked with cylinder in different position pneumatically, and the cylinders in different position combines the integrated cylinder group module. The pneumatic jacquard device renews the mechanism of jacquard device, designs s single energy signal, namely, the control signals and execution signals are both pneumatic signals to simplify the structure and modularity, so the total elevation of jacquard device is homologous to ordinary loom. The invention uses cylinder and lifts warp yarn through harness wire, avoids the complex parts of motor, drive shaft, gear boxes, upgrade arm, broach and so on in mechanical lifting harness wire device and the device is greatly simplified.
Description
Technical field
The present invention relates to a kind of fabric machinery, particularly a kind of air-actuated jacquard device.
Background technology
The different designs pattern of jacquard fabric is mainly realized by the various combination of warp thread lifting.Prior art and conventional art are relatively, the lifting of its heald all is to rely on to griffe the mechanical force pulling, descend by the restoring force of return spring, different is to select the control mode of warp to become electronics-electromagnetic component by traditional mechanical mechanism, the electronic jacquard machine so gain the name, the main motion form of shedding is the same in fact.
Though the electronic jacquard technology has developed into the suitable stage of ripeness, but exist:
1, the control signal electromagnetic force is a different physical quantities with carrying out the signal mechanical force, causes the jacquard attachment complex structure, and volume is bigger;
2, for improving the force-bearing situation of lifting-cord, the jacquard weave tap of being made up of control device and shedding mechanism often places the position of loom top up to 5～6 meters, and it is very big to cause complete machine to take up space, and it is many more to be carried warp thread, and the complete machine height is high more;
3, the very flexible that adapts to different fabric width looms.
Summary of the invention
The objective of the invention is to provide that a kind of energy signal is single, simple in structure, modularization, make the jacquard complete machine height air-actuated jacquard device suitable with ordinary loom for the deficiency that solves above-mentioned technology.
In order to achieve the above object, a kind of air-actuated jacquard device that the present invention is designed, it comprises the lift unit of the heald that heald, return spring and drive warp thread promote, the pneumatic unit that described lift unit is made up of cylinder and source of the gas, heald is connected with pneumatic piston rod in the cylinder, and cylinder is connected by gas circuit and source of the gas are pneumatic.The heald of the diverse location of described lifting diverse location warp thread can be connected with the cylinder of diverse location is pneumatic respectively, and the cylinder of diverse location is formed integrated form air cylinder group module.In order to improve control performance, accelerate the control reaction speed, can be provided with cylinder and being connected of source of the gas solenoid directional control valve and the pressure regulator valve that control cylinder is carried out on the gas circuit, the control input end of solenoid directional control valve links to each other with control device, described control device can mainly comprise electric cabinet and control computer, because the signal controlling to pneumatic means is conventional control technology, does not describe in detail at this.The solenoid directional control valve of control diverse location cylinder is formed integrated form electromagnetism reversal valve group, and integrated form air cylinder group module is connected with the solenoid directional control valve group is pneumatic by gas circuit, and the solenoid directional control valve group is connected by pressure regulator valve and source of the gas are pneumatic.Described pneumatic piston rod can be a flexible piston rod, and heald links to each other with flexible piston rod, and described cylinder can be a piston type distribution single-acting cylinder.Between cylinder and solenoid directional control valve, can be provided with the timing throttle valve.
The resulting a kind of air-actuated jacquard device of the present invention, by the mechanism innovation of jacquard attachment, it is single to design a class energy signal, and promptly control signal all is a pneumatic signal with carrying out signal, make it simple in structure, realize modularization, thereby make jacquard complete machine height suitable with ordinary loom.
The present invention adopts cylinder directly to lift warp thread by heald, removed mechanical type from and lifted complex component such as motor in silk device, power transmission shaft, gear-box, lift arm, broaching tool, and mechanism simplifies greatly;
Adopt integrated form single-acting cylinder pack module, not only be convenient to install, and can select the varying number module as required for use, adapt to the loom requirement of different fabric widths.
Because module size is little, can be arranged in order along fell, need not lifting-cord, and jacquard complete machine height and common dobbies height are as good as, and the fabric width increasing, when increasing the air cylinder group module, machine height is still constant; Simplified the jacquard attachment structure, greatly reduced the complete machine height, reduced machine and taken up an area of the space;
For improvement lifts the force-bearing situation of heald piston rod, pneumatic element is a mature technique the most in the MEMS manufacturing technology, therefore processing of the present invention, makes and has the good technical basis; The present invention has designed the piston valve actuating mechanism, makes piston be in pulled condition all the time, has solved the rigidity requirement to piston rod; There is not environmental pollution in Pneumatic Transmission.
Change the textile design artistic conception program of computer stored, solenoid directional control valve moves according to respective sequence, just can conveniently change weaving-pattern.Particularly the commutating frequency of solenoid directional control valve provides guarantee up to 100Hz for further improving the speed of a motor vehicle.
