Description
Technical field
The present invention relates to a kind of selecting mechanism of electronic jacquard machine, a kind of electromagnetic needle selection mechanism of electronic jacquard machine is set especially, for the needle selection of electronic jacquard machine.
Background technology
Jacquard needle selecting is a comparatively complicated process, start from World War II to the research of electronic jacquard shedding mechanism in the world to terminate, arrived the seventies, due to the application & development of large scale integrated circuit and electronic computer, the research of electronic jacquard machine achieves major progress.Nineteen eighty-three, First electronic jacquard machine is put on display as model machine in the textile machine exhibition of Milan, and after this many jacquard manufacturers list it in oneself development plan, can say from the eighties, let a hundred flowers blossom and a hundred schools of thought contend for textile industry, and growth momentum is fine.Electronic jacquard machine is compared with other Mechanical course jacquard, change creative in pattern control, though different electronic jacquard machines has different structures, but analyze from principle aspect, form nothing more than by following a few part: 1, electronic program device: correctly send shedding information, can with keyboard, display, the functions such as printing; 2, the switching mechanism of the signal of telecommunication and mechanical quantity: generally adopt electromagnet, the shedding information namely sent by program control device converts mechanical displacement to realize Mechanical course.The composition 1 of electronic jacquard control system, jacquard information disk: deposit jacquard information, 2, main frame: more than 80286 can with microcomputer or industrial computer, for reading and the people of jacquard information, sender set information, fault message
machine manages; 3, control interface: for process and the conversion 4 of jacquard information;, power-fail memory function interface: for the long term storage of technical management information and production leadtime information; 5, interface plate: for transmission and the hardware protection of jacquard information; 6, jacquard weave driver card: carry through controlling for needle selection; 7, integrated power supply: adopt decentralized power supply, solid state power supply mode, for the power supply of jacquard head.8, sensor: various fault is as the collection of the signal such as cracked ends, staplings, and input main frame, deals with in good time.
And the needle selection of electronic jacquard is an extremely important step, existing technology is that electromagnetic force changes mechanical force into, and the operation principle that electromagnetic force changes mechanical force into will divide four working stages, the stage 1: left side sheet hook promotes, the right sheet hook declines, heald motionless (i.e. heald not opening); In the stage 2: left side sheet hook rises, the right sheet hook declines, and in pulley, rise and fall are offset, and heald is still motionless; In the stage 3: during the sheet hook rising peak of the left side, electromagnetic valve powers up sheet hook and tangled by adhesive, and namely sheet hook in the left side maintains static, when the right sheet hook promotes, heald moves up, and produces opening; In the stage 4: on the sheet hook of the right, peak stayed by left side sheet hook, and sheet hook rises to peak when the right, produce maximum open.
Also as Staubli electronic jacquard machine hooks when the movable hook on left (right side) is kept hook, when right side (or left side) griffes up to move, heald is just raised, formation top shed, otherwise is lower shed.Compare with BONAS: operation principle is substantially identical, just the complexity of mechanism has difference, and the mechanism of Staubli is comparatively complicated.
But existing needle selection mechanism of electronic jacquard, due to the principle using electromagnet to attract irony parts, so the volume of its mechanical part is comparatively large, makes the pin number in unit are little, thus limits the lifting of its efficiency.
