Abstract
The invention provides a method and a device for uniformly controlling the unwinding tension of an automatic winder. The device is characterized in that: a sensor is arranged on a fixed unwinding balloon breaker and is connected with a control system; the winding position of each single spindle is provided with a lifting device; if the sensor cannot sense yarns on a bobbin in the process of unwinding the bobbin, the control system sends an ascending command to the lifting device at the winding position, and the lifting device stops ascending when arriving at a predetermined position; after the yarns are wound, the bobbin detection sensor sends a bobbin-free command, the lifting device descends to the initial position, and the bobbin is changed; and a tray with a bare bobbin is moved to a bare bobbin conveying belt, and a bobbin tray on a full bobbin conveying belt is switched to the winding position. The method and the device ensure that the height of the yarn guide position of the yarns relative to the yarn unwinding position on the bobbin is unchanged, the yarns are in an optimal unwinding state, and the unwinding tension of the whole bobbin is uniform, so that the unwinding resistance of the yarns is reduced and the bobbin is easy to unwind.
Description
Technical field
The invention belongs to technical field of textile machine, relate to for thin network connection and the unwinding tension control device of large yarn storehouse type automatic winder and the improvement of control method, is a kind of even control method and control setup of unwinding tension of automatic winder specifically.
Background technology
In the automatic winder that uses both at home and abroad at present, no matter be yarn storehouse type, or thin network connection type, its unwinding control and doff position are all fixed, therefore in the whole cop unwinding process, because of the difference of unwinding balloon shape, cause the unwinding tension in the unwinding process irregular.Cause easily doff process tension fluctuation, it is irregular to form tension force, causes easily a yarn tension irregular, and the problems such as chrysanthemum core, the inadequate kind of indivedual kinds such as yarn strength be the phenomenon such as easily broken in the doff process, causes easily quality problems and reduces production efficiency.
Application number is in 200810138450.1 the Chinese patent, the unwinding balloon breaker is movable, but be not suitable for thin network connection automatic winder, application number be 92110401.4 and the Chinese patent of 200810184902.X in, its unwinding balloon breaker along with cop unwinding yarn amount to descending, this take-off device is guaranteeing that unwinding tension has certain effect aspect even.But its unwinding balloon breaker is to descend with the unwinding yarn point on the cop, the thread friction segment length, and the unwinding resistance is larger, and it is more to make yarn produce filoplume, and yarn qualities is had a negative impact.
Thin network connection is that automatic winder links to each other with spinning frame, and the ring bobbin that directly spinning frame is fallen by transfer passage is delivered to each single ingot of automatic winder, and sends the blank pipe pallet behind single ingot doff back to spinning frame by transfer passage; Large yarn storehouse type automatic winder is exactly to pour the cop that spinning frame falls into large yarn case, then pour reciprocating sieve and vibrations basin in batches, by actions such as separation, conveyings, spool is put on the empty pallet, deliver to each single ingot of automatic winder, and the blank pipe pallet behind single ingot doff sent back to by transfer passage insert the yarn position, plug the circulation that continues the front behind the cop.Thin network connection and large yarn storehouse its tube ejector of type automatic winder are identical, and tube ejector adapts to the above mode of movement.
Summary of the invention
The present invention is directed to the problems referred to above that prior art exists, a kind of even control method of unwinding tension of automatic winder is provided, control method is simple, reasonable, guarantees that whole cop unwinding tension is even, and the unwinding yarn resistance is reduced, and helps the light unwinding of cop.Also provide a kind of automatic winder evenly to control the unwinding tension device, it is rational in infrastructure, can guarantee that whole cop unwinding tension is even, and the unwinding yarn resistance is reduced, and helps the light unwinding of cop.
