Description

Manufacture the work station of the weaving loom of cross winding bobbin

Technical field

The present invention relates to the work station of the weaving loom of manufacture cross winding bobbin, have the guide for surrounding thread path logical Road, yarn-guiding duct prolong in yarn feeding device (feeding bobbin for being especially located at unwinding position) between the winding device of work station It stretches, and there is multiple support housings and/or supporting section, they are used to install different yarn treatments or yarn monitoring device, Especially yarn splicing device.

Background technology

In textile industry, different designs related with the manufacture weaving loom of cross winding bobbin are known, such as from Dynamic winding or spinning machine, it is some of to describe in detail relatively in the patent literature.Sutomatic winding machine is not only in its numerous work The supply side for the new spinning bobbin stood has differences, and in terms of the formation of the yarn operating path of its own work station It is different.This is equally applicable to the spinning with the spinning unit for producing yarn (yarn is then fed to thread path) Machine.

In the case of the weaving loom of manufacture cross winding bobbin, especially sutomatic winding machine, this weaving loom is had long been known that By machine itself new spinning bobbin can be provided in the logistics system of bobbin and casing conveying device form, such as These described in DE102005001093A1 or DE102014002149A1, which is connected to and comparable logistics system The weaving loom that system upstream is connected, preferably ring throstle.

Related with sutomatic winding machine to be well known that, the work station of this weaving loom is equipped with so-called round library, more A spinning bobbin is stored in round library.If desired, for example, such as DE19539762B4, DE19816188A1 or As described in DE102008057806A1, such circle library is manually refilled by operating personnel.

The work station of these widely used weaving looms usually has and is at least beaten to greatest extent in front in textile industry The thread path opened, therefore operating personnel are readily able to see the thread path.

It means that on the work station of this weaving loom, the yarn extracted out from the spinning bobbin positioned at unwinding position Really pass through different yarn monitoring or Yarn processing device, such as yarn under working sensor, yarn tensioner, have yarn cutting Yarn clearer, yarn tension sensor and the optional waxing attachment of device, reach up to the winding device for being maintained at work station In cross winding bobbin, but it keeps visible in maximum possible degree.

In addition, the work station designed in this way is equipped with Yarn Connecting apparatus (preferably pneumatically-operated yarn Splicing device), pneumatically-operated suction nozzle and also being capable of pneumatically-operated clamping pipe.

Suction nozzle and clamping pipe are connected to the negative pressure system of weaving loom itself, it is cut in yarn breakage or controllable yarn clearer Afterwards, it is ensured that the yarn ends of the upper yarn operated on cross winding bobbin or the yarn under working that is fixed in yarn tensioner Yarn ends are picked and are delivered to yarn splicing device.In order to ensure the yarn carried out in yarn splicing device connects always With the appearance almost the same with yarn and the intensity almost the same with yarn, two yarn ends before splicing also by It removes, accurately cuts into length, is ready to and be appropriately positioned in the splicing tunnel of the splicing prism of yarn splicing device In.

For this purpose, pneumatically-operated holding and shredding tubule are not only set in the region of this yarn splicing device, these Yarn splicing device is slightly concave usually relative to conventional thread path, and be additionally provided with yarn clamp and cutter device with And so-called fournisseur.

However, the weaving loom about manufacture cross winding bobbin, also has disclosed, each work station, which can have, to be closed Box-like yarn-guiding duct, each yarn-guiding duct are equipped with multiple supporting sections or support housing, various yarn monitorings and processing unit In supporting section or support housing.

For this work station, such as the work station be described in detail in DE102010049515A1, along its whole length The thread path between the feeding bobbin positioned and the winding device of work station in unwinding position that is located at be designed as closed type and lead Yarn channel, and can have in particular segment and be applied to its negative pressure.This means that vacuum flow can be implemented in yarn-guiding duct, The flow direction of vacuum flow can be specified with limited way.

As being described in detail in DE102010049515A1, by generating corresponding negative pressure in closed type yarn-guiding duct Flowing, yarn ends are transferred to the yarn splicing device on the work station configured in this way, this feelings interrupted in winding It is required under condition.This means that using the work station with this design, rotary suction nozzle or rotation clamping pipe are not needed.

Suction nozzle is omitted in this and clamping is managed, and relevant bulky driving unit is especially omitted, leads to such situation: Can be from the work station of front free access compared with thread path, the work station to work together with closed type yarn-guiding duct has aobvious Write small overall width.

By being integrated into the monitoring of various yarns and processing unit in the yarn-guiding duct of thread path, additionally it is possible to ensure The yarn run in winding process is largely environmentally isolated with, this have the effect of it is very positive, especially for The design of work station pollution.

However, have the shortcomings that the work station of this closed type yarn-guiding duct is, largely, operating personnel from Yarn is not seen in spinning bobbin to the path of cross winding bobbin, therefore operating personnel can not reach winding device according to it Requirement come check operation yarn whether always operation pass through yarn monitoring device or the whether normal work of yarn splicing device Make.This means that operating personnel can not differentiate whether yarn is correctly monitored before being wound up into cross winding bobbin, Huo Zheru Whether fruit has if necessary produced suitable Yarn connecting.

These difficult observation conditions are still a distinguishing feature of work station, and the work station is equipped with closed type guide Channel is further equipped with the round library of the new spinning bobbin of supply.

In the work station with this design, yarn splicing device is not only like the common such phase of closed type yarn-guiding duct To being snugly arranged in support housing, and support housing is also covered by round library at least partly.This means that splicing rib The splicing tunnel of column and yarn splicing device is almost invisible, especially with closed type yarn-guiding duct and is being further equipped with circle In the work station in shape library.

It since operating personnel are difficult to monitor splicing, and is difficult to detect splicing result, therefore operating personnel are difficult to sentence Whether the amendment for the splicing parameter whether disconnected splicing apparatus works normally or set is conducive to yarn splicing device.

In the patent literature, the weaving loom for also having been combined manufacture cross winding bobbin discloses making for image collecting device With.

For example, DE19836071A1 describes a kind of method or relevant apparatus, can be examined by this method or relevant apparatus Survey the yarn residue on spinning bobbin.

Using this method of the prior art, spinning bobbin to be checked is irradiated using the light of at least one light source, by spinning The light of yarn bobbin reflection is captured by image collecting device (such as CCD camera) and is converted into digital image data.Number Image data is transported to assessment computer and by computer evaluation, so as to estimate yarn residue on spinning bobbin In the presence of.

DE102008029575A1 also discloses a kind of weaving loom of manufacture cross winding bobbin, with multiple work stations And at least one service unit, the service unit can be moved along work station to operate and/or safeguard each work station.

For service unit there are one camera, it is configured to generate the image of service unit and/or work station, and by the figure Control and computer unit as being transmitted to weaving loom.Control and computer unit handle transmitted information, and using should Information controls the operation and/or control of service unit and/or work station.

Invention content

Based on the above-mentioned prior art, basic task of the invention is to improve the manufacture with closed type yarn-guiding duct to intersect volume Around the work station of the weaving loom of bobbin so that the operation of yarn treatment or yarn monitoring device is to be easy to for operating personnel Understand, and can be corrected if necessary.

The settling mode of the task is that yarn-guiding duct has monitoring section, yarn in the region of support housing or supporting section Processing or yarn monitoring device are located in the support housing or supporting section, and the monitoring section is by means of that can be connected to computer The optical pickup of device can be used for monitoring mounted on support housing or the yarn treatment in supporting section or yarn monitoring device.
