The yarn splicing device of the station of weaving loom for manufacturing cross winding bobbin

Technical field

The present invention relates to the yarn splicing device of the station of the weaving loom for manufacturing cross winding bobbin, for without knot connection two A loose thread includes that the yarn channel of connecing with acceptable airflow function connects yarn prism, yarn insertion is sewn on connect yarn during It stays open.

Background technology

In the textile industry, it is used for without the yarn splicing device for tying two loose threads of connection already with a variety of different embodiments Belong to the prior art.

Especially the such Yarn Connecting apparatus used in connection with sutomatic winding machine station allows the gas by two loose threads Scrollwork is flowed to manufacture Yarn connecting, and not only there is the intensity similar to yarn, also have the appearance almost as yarn.

On the station of such sutomatic winding machine it is well known that when a station goes out wherein in winding process When existing yarn breakage, or disconnected when yarn clearer cut-out as defined in need to press because of yarn flaws on a station wherein The loose thread of yarn is taken back to by special airflow apparatus in yarn splicing device region first.That is, suction nozzle sucks back intersected coiled bobbin The so-called upper yarn for falling on cross winding bobbin surface of son is simultaneously perhaps also put into this and connects yarn after yarn flaws are removed Device connect yarn prism connect yarn channel.The loose thread of upper yarn is also threaded at this time set on the yarn clipping machine connect above yarn prism Structure and positioned at connecing in the yarn cutting mechanism below yarn prism.Then or at substantially the same time, from feeding in unwinding position To bobbin and be generally secured to the loose thread of so-called yarn under working in yarn tensioner by acceptable negative after winding interrupts The clamp yarn cop of pressure be placed into connect yarn prism connect yarn channel.

The yarn of yarn under working is also threaded at this time set on connecing yarn clamping mechanism below yarn prism and set on connecing yarn prism Yarn cutting mechanism above body.

Then, loose thread is truncated by yarn cutting mechanism, is inhaled into so-called holding shredding pipe and is ready to there Yarn process is connect for subsequent.That is, loose thread is keeping breaking away from its yarn twist substantially first in shredding pipe, then they pass through yarn Line adjuster, which is pulled back, connects the connecing in yarn channel of yarn prism so that loose thread is alignedly seated in that connect yarn logical side by side toward each other And it then can be by air-flow scrolling in road.

As described above, the various embodiments of such yarn splicing device are known and part is in many protections application It is expressly recited.

Such yarn splicing device for example can be as described in DE3906354A1 equipped with the lid of swingable installation Part, closing connects the yarn for connecing yarn channel of yarn prism and penetrates seam or yarn splicing device can be with cover piece upwards during connecing yarn Have as described in EP1522517A1 and connect yarn channel, yarn penetrate be sewn on connect yarn during keep up it is unlimited.

In addition, such connect connecing yarn channel and being designed as disclosed in such as DE3906354A1 for yarn prism At being straight and single type, or there is two-piece design structure as described in such as DE3612229C2.

That is, connecing connecing yarn channel and can having that there are two radially slightly mutually stagger setting to connect yarn channel for yarn prism Chamber, have respectively itself be tangentially passed through connect yarn air mouth.

In order to prevent the yarn air that connects that loose thread flowed into during connecing yarn, blowout connects yarn channel upwards, especially connects at it Yarn prism connects in the yarn splicing device that yarn channel stays open upwards during connecing yarn advantageously, connecing the yarn of yarn channel The width coordination for being inserted into seam is matched with thread material to be processed.That is, when processing delicate yarns material, yarn is inserted into seam should Narrow as possible, being connect yarn air to avoid spun yarn head, blowout connects yarn channel upwards.

But the yarn prism that connects constituted in this way is very unfavorable when processing thicker thread material, because will be by comparing It is very that the loose thread that thick thread material is constituted penetrates seam ground and reliably connect into the yarn channel that connects of yarn prism is connect through narrow yarn Difficult.

In order to also the yarn prism that connects of uncovered be utilized to process different thread materials, therefore so far commonly about connecing The width that the yarn of yarn channel penetrates seam takes compromise.That is, the yarn for connecing yarn channel for connecing yarn prism penetrates the width one of seam As be generally set to the width be selected as it is bigger about delicate yarns material, but usually very when processing rove wire material Close to tolerable lower range.

Invention content

In view of the yarn splicing device of aforementioned type, the present invention is based on following tasks, provide a kind of yarn splicing device, here, connecing yarn The width that the yarn for connecing yarn channel of prism penetrates seam always most preferably adapts to the requirement of thread material to be processed.
