Definitions
- the present invention is in the field of methods and apparatus for making coregam.
- a core yarn is a yarn consisting of a filament (core) and a fiber sheath wrapped around it.
- the soul is usually made of elastomer, which gives the yarn elasticity.
- the Applicant has long specialized devices on the market, in which side or next to a drafting of a ring spinning machine one or0 more feeders are arranged, by means of which a filament is fed to the spinning process before the delivery roller of the drafting system.
- the filament is spun with the stretched by the drafting fibers of a roving, so that it later forms the soul of the coregame.
- EPl 561 845 of Rieter Maschinenfabrik AC was published in 2006 and deals with a device for the production of fancy yarn.
- the task is very general in improving and accelerating the manufacturing process of Coregam.
- the device provides that a core thread (filament) is monitored for breakage prior to combination with the fibers of a roving, so that it is quickly recognized whether a core thread is broken.
- the monitoring is not specified more precisely and should be possible in any way. Mention may be made of mechanical monitoring which senses the presence of the pre-thread, optical devices which view the core thread, or else capacitive or inductive monitoring.
- the device should be suitable for checking whether a Corefade meets certain specifications.
- the core thread is associated with a roller which rotates with the core thread.
- Corresponding devices have long been known by the applicant.
- the object of the invention is to show a device for monitoring a process for producing a coregame.
- the applicant of this invention has long known devices which monitor, via an electrical sensor, the movement of the filament guided by a special roller, on the basis of the rotation of the roller, and so confirm if there is a problem with a spinning station. These devices have proven themselves in practice in principle.
- An embodiment of the invention discloses another method for monitoring the manufacturing process of a core, or displaying a broken filament. Also disclosed is a thread monitoring and separation device (henceforth monitoring device) for carrying out the method.
- a filament which forms the core of the core after the spinning process, is guided past a certain tension adapted to the dimensions of the filament during spinning (normal operation) on a deflection roller of the monitoring device, which thereby acts against the force of a spring and / or gravity a first (raised) position is brought and so keeps a separator open.
- one or more other deflection elements for example in the form of eyelets, etc. may be used instead of a deflection roller. It should be noted that the response is not adversely affected.
- the deflection roller is operatively connected via a mechanical connection to a separating mechanism normally arranged in the inlet region of the drafting system, which acts there on the supply of the fiber roving and interrupts it if necessary.
- a separating mechanism normally arranged in the inlet region of the drafting system, which acts there on the supply of the fiber roving and interrupts it if necessary.
- the deflection roller is brought into a second position, for example due to gravity and / or the force of a spring, as a result of which the separation mechanism begins to act on the roving and likewise feeds it into the corresponding spinning station is interrupted, so that the spinning process at the affected spinning station comes to a standstill.
- the separation mechanism may be a blade which is self-locking, so that the fibers of the roving are separated with a minimal external force as a result of the conveying action of the drafting system.
- individual rolls or pairs of rolls provided with a self-locking / self-braking mechanism can be used, which act on the roving, if necessary, and prevent its supply.
- a pawl acting on a roller or a pair of rollers which does not engage in normal operation due to an operative connection with a deflection roller of the filament. As soon as the filament is no longer sufficiently tensioned or tears, the pawl engages and thus blocks the actively connected roller or the pair of rollers, so that the further supply of the roving is stopped.
- the rollers can be actively pressed against each other. It is also possible to provide the rollers with a corrugated and / or rubberized surface. Another possibility is to use two rollers that are designed eccentrically.
- the deflection roller is operatively connected via a rocker with the separation mechanism.
- the mechanism is balanced so that the operating voltage of the filament is sufficient to bring the separation mechanism in the first position.
- the separating mechanism consists of a self-locking blade, which is rotatably arranged about an axis and acts obliquely from above against the flow of the fibers on this. Balance weights or other tare means serve to adjust the necessary lifting force to hold the blade in the open position. If necessary, the length of the lever arm can be adjusted. After falling below a defined load level of the separation mechanism causes a suppression of the further fiber supply.
- a biased mechanism may be provided which is triggered when the operating voltage of the filament falls below a defined load level.
- the monitoring device with a blocking device by means of which the separating device can be held in the open position.
- a detent element or a latch which can be inserted or folded as required to block the movement of the blade in the open position.
- the device is not only suitable for use on ring spinning machines, but also on other spinning machines suitable for the production of Coregam.
- One embodiment of the invention relates to a monitoring device for producing coregam.
- the monitoring device comprises a front deflection roller for deflecting a filament, which is usually arranged above the delivery rollers of a drafting system and the precise feeding of the filament is used for a spinning process.
- a separating device In the inlet region of the drafting a separating device is arranged which has a rear guide roller for deflecting the filament.
- the separating device serves to prevent the inflow of fibers into the drafting system as a function of the stress level of the filament and / or the presence of the filament.
- the front pulley and separator may be attached to a traverse rail of the spinner so that they are laterally deflected back and forth during the spinning process.
- the rear pulley is advantageously arranged obliquely above the drafting system. Other embodiments with only one pulley are possible.
- the separation device has a rear deflection roller which is operatively connected to a blade which serves to interrupt the fiber flow.
- the rear Umlenkrol- Ie and the blade via a rotatably mounted about an axis rocker operatively connected.
- the length of the lever arm can be designed adjustable.
- the moving parts are advantageously balanced so that the forces on the filament remain below a critical level.
- the blade is self-locking with respect to the fibers fed, so that the fibers, by virtue of their movement, pull the blade into contact with the fiber stream upon contact. As a result, only minimal external forces are necessary to prevent the fiber flow.
- Another embodiment of a separating device includes a pawl which acts on a roller or a pair of rollers.
- the pawl is operatively connected to the guide of the filament, eg a pulley or diverter, and does not engage under normal operating conditions when the filament is present and sufficiently tensioned. As soon as the filament breaks or is no longer sufficiently tensioned, the pawl engages and stops the further fiber supply to the drafting system, so that the spinning process comes to a standstill.
- the separator can with an inlet channel be equipped, which is arranged in front of the blade seen in the direction of fiber travel. If necessary, the separator may comprise a condenser which serves to supply the fibers to a drafting system. If necessary, the separation device may comprise sensors which detect the position of the blade, the rotational speed of the rear deflection roller and / or the fiber volume flowing through the capacitor.
- the rear and / or the front deflection roller may be provided with an optical marking, which visually indicate the rotation of the deflection roller.
- the rear and / or the front guide roller can be arranged perpendicular to the conveying direction of the yarn (in the axial direction) adjustable so that the device is precisely adjustable and thus also for the processing particularly thin game is suitable.
- the front deflection roller can be designed so that it is adjustable in position during operation.
- the device according to the invention can be provided in the form of a kit for retrofitting an existing spinning device.
- the kit includes at least one of the described separation devices configured to be compatible with an existing spinning device.
- the kit contains as needed a front guide pulley which serves to feed a filament to a spinning process in the delivery area of a drafting system. Also can be included by means of the front pulley above the delivery area, if necessary, adjustable, can be positioned.
- a process for monitoring a production process of Coregam has the following simplified process steps: a. Providing a separating device which is arranged in the inlet region of a drafting system of a spinning machine and has a rear guide roller, which is operatively connected to a blade which is suitable for interrupting the supply of a roving to the drafting system; b. Deflecting a filament, which later forms the core of a coregame, over the first rear diverting pulley, wherein the pre-tensioning of the filament is maintained above a defined stress level, such that the rear diverting pulley deflects due to the stress level, and thereby operatively connected blade is brought into an open position; c. Spinning the filaments drawn through the drafting system into a coregam by feeding the filaments from the drafting equipment in the region of the delivery cylinders of the drafting equipment and then turning the fibers and the filament into a yarn.
