Description
Technical field
The present invention relates to the multi-thread defeated yarn methods and its device of a kind of electromagnetic levitation type circular knitting machine, belong to textile industry weaving loom
Tool technical field.
Background technology
Electromagnetic levitation type, which directly drives knitting needle knitted jacquard circular knitting machine, to be moved up and down using electromagnetism power drive knitting needle to complete entirely
Braiding process is compared to traditional knitted jacquard circular knitting machine triangular cam driving mechanism, during this straight drive mode can be saved
Between mechanical transmission link, realize " Zero-drive Chain " of needle selection process, not will produce rigid shock during needle motion, rub
The shortcomings of abrasion, energy loss and noise, greatly improve the braid efficiency of circular knitting machine.But current electromagnetic levitation type directly drives knitting needle
The yarn-feeding device of knitted jacquard circular knitting machine cannot meet multi-thread defeated yarn requirement, and not have good solution, become further
The important link that electromagnetic levitation type directly drives knitting needle knitted jacquard circular knitting machine braid efficiency is improved, patent of invention has been authorized《It is double-deck
Electromagnetic levitation type directly drives knitting needle knitted jacquard circular knitting machine》（ZL201510515739.0）, driven by magnetic levitation system connecting rod mode
Dynamic knitting needle, Shu Sha mechanisms are then driven by a set of planetary gear mechanism, its advantage is that using connecting rod mode, increase adjacent magnetic suspension
Outer barrel gap eliminates the torque of knitting needle bending.However in actual use, there is following some deficiencies in this kind of yarn-feeding device
Place：
（1）A pair can only be arranged at present（I.e. two）Defeated yarn bobbin, two defeated yarn bobbins are arranged symmetrically, and the certain angle of each self-contained
Degree installation, can not achieve multi-thread defeated yarn, cannot be satisfied braiding diversity requirements.
（2）Thread-feeding device is mounted on a set of planetary gear mechanism, and Thread-feeding device not only will together revolve round the sun with defeated yarn bobbin, but also
Also want rotation, it is therefore desirable to which two independent driving units, jointly controlling between two driving units is complex, and coordinates
Kinematic accuracy is relatively low.
On the other hand, old-fashioned tube payingoff mechanism Thread-feeding device mechanism is arranged symmetrically in a plane, simultaneously by connecting rod connection
Transmission, the tube payingoff mechanism needs a set of stepper motor driving unit that the tube is driven constantly to rotate, and the defeated yarn
Device then needs another set of stepper motor driving unit to drive, and stepper motor driving unit drives a set of planetary gear machine by synchronous belt
Structure rotates, and planetary gear mechanism drives the Thread-feeding device to rotate again, during which described in tube payingoff mechanism often turn over a circle and also need to
Its position is detected to compensate, not only needs two sets of additional driving units in this way, but also to detect in real time, and structure is multiple
It is miscellaneous.
In view of the above-mentioned problems, it is necessary to design a kind of multi-thread defeated yarn method and its dress for electromagnetic levitation type circular knitting machine for pole
It sets, while meeting defeated yarn diversity requirements, moreover it is possible to solve the problems, such as above-mentioned already present.
