Description

Repiece bar brake apparatus

Technical field

The present invention relates to rotor spinner yarning part place repiece bar brake apparatus, on this yarning part, each spinning unit comprises the sliver feed motion, every yarn feeding device, spinning rotor and coiler device, this coiler device comprises work beam and pressure roller and the take up roll of rotational line tube is housed on it.

Background technology

On each yarning part of above-mentioned known rotor spinning machine a spinning unit is housed, this spinning unit comprises sliver feed motion, relevant to yarn feeding device, the line that separates under suction function is pulled to the spinning rotor inner space every yarn feeding device from this, and they assemble, generate tape in feeder then.The rotation of spinning rotor makes tape twist into yarn, and yarn passes separator tube from spinning rotor and passes coiler device by work beam then.This yarn is subjected to the monitoring of a sensor, and this sensor sends a signal to control module when yarn breaks, and stops to send to of sliver thereby control module disconnects the electromagnetic clutch of sliver feed motion, thereby stops the operation of this yarning part.The spinning that available so-called repiece process is recovered this yarning part, in the repiece process, this end of yarn is inserted back recovery sliver supply in the spinning rotor, and the feasible line of newly supplying, separating can be twisted with the insertion end of yarn and is connected, thereby can recover the extraction and the coiling of yarn immediately.Usually the manual repiece process of carrying out, promptly the required institute of repiece is undertaken by the spinner in steps, and the spinner must carefully finish each action of repiece process by proper order.Because it is short, therefore very high to spinner's requirement to give the time compole of repiece process, the spinner must just can finish high-quality repiece process through long-time training and practice.Carrying out by hand the repiece quality that the repiece process obtains can't be guaranteed.

Therefore in order to alleviate spinner's work load, each yarning part is equipped with spinning mechanism in addition, and the sequential of this spinning mechanism is decided by the spinner.Thereby the subject matter of manual repiece, promptly the steady quality problem no longer occurs.

As use the automatic rotor spinning machine, and manual repiece is replaced by automatic operation, and this automatic operation is to be undertaken by the automatics of lateral shuttle motion.Its shortcoming is the cost height, to spinner's specification requirement height, time-consuming and can't obtain 100% repiece result when changing parts and do technological adjustment.Thereby therefore carry out unsuccessful time and again the moving on to of repiece and must carry out repiece by hand again when the next one breaks end the position when automatics.

Consider above-mentioned shortcoming, develop various improvement projects, for example each yarning part at rotor spinner uses semi-automatic spinning-in system.When a yarn repiece, this line tube is fixed on this cocked position after must lifting the line tube of semi-automatic spinning-in system with hand.This end of yarn with hand location, measure the separator tube that is directed to spinning rotor behind the repiece end that generates yarn after the length.Yarn is put into string-up position on this operating position before the repiece, use then the outer deflection piece of distributor and stroke for example a default repiece bar yarn is remained on this position with extracting roller, if they are not far from one another mutually.Use an electronic-controlled installation in the concrete time interval, making the arrangement for deflecting operation of sliver feed motion, dropout, also make new yarn supply operation and line tube break away from cocked position and place on the movable roll.Carry out with scheduled timing as all these actions, then restart to reel, spinning rotor is produced yarn again.Be equipped with at these and use power supply component to control each mechanism in yarning part of semi-automatic spinning, they are untied to the cocked position of line tube, for the locking of the stroke of line roller.

The scheme of semi-automatic repiece is usually very complicated, owing to must accurately control many mechanisms and power supply component and also control system is had high requirements owing to the deviation of behavioral characteristics.

In order to solve a part of the problems referred to above, design a kind of layout, according to this layout, one operating position comprises the device that yarn is retracted the line tube, it is connected with a trip gear with safeties in stowed position retention wire tube stability, and this trip gear is relevant with the ready position that yarn sucks in the spinning rotor.These safeties have independently an electromagnet and a release electromagnet, these electromagnet and carry out the sychronisation that repiece controls for the electromagnetic clutch of line through jockey and and be connected.This means that the element of a large amount of function associations must be housed in all working position, and this causes cost to improve greatly in the spinning machine of multi-section position.

Designed a kind of all one's life head rod of using work beam is fixed on device on the upper position for addressing this problem, this repiece bar is used for keeping repiece simultaneously.The directly fixing and control of this repiece bar by the directly actuated electromagnet of control system.The shortcoming of this design comprises: it is very big, very high to the precision of each parts and the unified requirement of regulating all working position to untie repiece rod lock required electric power.

Another common drawback of all existing semi-automatic spinning-in systems is to use the electromagnet of moving core, and this is inapplicable for the how grey environment at cotton mill, thereby very high to the seal request of the moving core of electromagnet.

The utility model content

The purpose of this invention is to provide a kind of repiece lever apparatus of eliminating reliable, simple, the cheap semi-automatic repiece of the problem that has semi-automatic spinning-in system now to the full extent.
