It is appreciated that type spinning machine in free end according to the present utility model allows to overcome background skill from the content having been described
The shortcomings that being proposed in art.
For the solution of background technique, new yarn picking up system has the advantages that several.
Major advantage is:
1. reducing the quantity for being adapted to carry out the device of circulation；
2. reducing the yarn access between a device and another device；
3. the higher precision during yarn cutting step；
4. improving the efficiency that machine integrally manages.
In more detail, the reduction for being adapted for carrying out the device of circulation needs to reduce overall dimensions certainly, is not only physical unit
Overall dimensions, but also volume needed for the movement including actuation means itself.
The quantity for reducing device helps to limit cost, because not only reducing redundancy structure (sensor, motor, actuating
Device etc.), and reduce relative energy consumption.
The global reliability of system will also improve, because the possible breakdown of mechanical part will reduce (quantity reduction) and go back
Necessity maintenance to device will be reduced.
In addition, the integrated of different device allows to eliminate extra function, such as, will repeat in preparatory unit to collect
Suction system, centering unit or the various sensors of waste material and the electric motor system for allowing device displacement.
Device using small number of manipulation yarn means the yarn access from a device to another device
Quantity is reduced；Particularly, instead of by known system (nozzle/centering unit, centering unit/preparatory unit, preparatory unit/supply
Unit) three via intermedias imagining, the utility model only provides a via intermedia (nozzle/feed unit).
Less access allows to save the time that yarn is transferred to another device from a device.
Small number of access also means that a possibility that yarn " is escaped " during transfer is lower, as a result is restoring to recycle
When lose machine time to restore yarn.
The another advantage for reducing yarn transfer is, for example, leading to during the access from a device to another device
The moving component for crossing rubbing device reduces the impaired possibility of yarn itself.
Another benefit of new picking up system bring is that higher precision will be brought in cutting step: ready yarn
End between the point clamped between the roller of feed unit at a distance from be precisely preserved in the etching process, and since yarn is not necessary
Further access, therefore precision having the same are crossed, which will be admitted to yarn efferent duct.
The length of the thread segment is accurately to be very important during the step of being inserted into yarn efferent duct: being repaired
The repairing quality realized during step, and therefore the quality of entire reel for yarn and thread is decisively determined by it.
The another advantage obtained from new picking up system is machine pipe caused by the reduction due to the yarn treatment time
It manages more efficient, is also reduced because not only reduce access, and during yarn access in the case where " loss " possible
Program re-executes the time.
The raising of efficiency results also from the reduction (less engine, less sensor etc.) of energy consumption and operates it
Needed for less energy.In addition, reducing maintenance (with less equipment) has positive influence to whole machine efficiency.
In order to meet possible and specific needs, those skilled in the art can machine to the utility model and repairing
