Description
Technical Field
The invention relates to a tube for a textile machine for producing wound bobbins, comprising: a yarn inlet; a connection for a vacuum source; and a detection zone designed to monitor the inside of the bobbin by means of a yarn detection unit arranged outside the bobbin. The invention further relates to a textile machine for producing wound bobbins, comprising such a bobbin.
Background
Various embodiments of a bobbin tube of the type mentioned in the introduction are used in textile machines for producing wound bobbins, in which the yarn arranged in front of the yarn inlet is sucked into the bobbin tube, usually by means of a vacuum source. Such bobbins are used, for example, in winding machines for taking up thread ends on the winding or unwinding bobbins, so that they can be used in a yarn splicing device. In rotor spinning machines, the yarn end is fed to the spinning box opposite to the direction of manufacture for splicing. In order to detect the end of a thread in such a bobbin, it is known to provide the bobbin with a thread detection unit which monitors the interior of the bobbin in a detection zone of the bobbin and detects the thread placed therein. Bobbins are also present in winding machines with a so-called closed yarn path. That is to say, these textile machines have a multi-part thread guide channel or a multi-part bobbin which surrounds the thread path and extends between the feed bobbin located in the unwinding position and the winding device which produces the wound bobbin.
DE2531044a1 describes a device for detecting a thread in a channel through which air flows and which is part of a suction device for picking up the thread end on the winding bobbin side. At the bend, a number of openings are provided in the tube wall, aligned opposite each other, for receiving a sensor device formed by a radiation source and a receiver. The sensor device forms a grating that spans the tube and indicates that the yarn is disposed within the tube when the grating is intercepted by the yarn.
In order to ensure reliable yarn detection, it is necessary to protect the tube from soiling throughout its periphery in the region of the grating to ensure a continuous beam path from the radiation source to the receiver, which are arranged on opposite parts of the tube. But the device is very prone to failure because of the tendency to soil.
Furthermore, the need to provide an opening for the sensor device leads to an increased complexity of the bobbin design. Said openings also have the disadvantage of causing air turbulence inside the bobbin. These result in higher energy consumption during the creation of the vacuum and cause a risk of leakage. Eventually, the flow conditions in said area lead to a more severe accumulation of contaminants at the opening, which causes the measuring unit to become unusable faster.
Disclosure of Invention
A first aspect of the invention therefore relates to a bobbin for a textile machine, comprising a yarn inlet, a connection for a vacuum source and a detection zone designed for monitoring the interior of the bobbin by means of a yarn detection unit arranged on the outside of the bobbin.
The bobbin according to the invention is characterized in that the yarn detection unit comprises a transmitter unit for introducing electromagnetic radiation into the interior of the bobbin and a receiver unit for detecting any reflection of the radiation caused by the yarn placed inside the bobbin.
The yarn detection unit according to the invention is positioned in the detection zone of the bobbin. The detection zone is designed such that electromagnetic radiation emitted by a transmitter unit arranged on the outside of the tube enters the tube interior and radiation reflected by the yarn in the tube interior can be detected again by a receiver unit arranged on the outside. This detection zone configuration takes into account the wavelength of the electromagnetic radiation radiated by the transmitter unit and the receiver unit, so that openings in the yarn tube which were intended to receive the transmitter unit and/or the receiver unit can be dispensed with. The omission of such openings also means that no leakage occurs in the region of the transmitter unit and/or the receiver unit and that the flow behavior in the bobbin is not adversely affected, which is why there is no higher degree of contamination in the region of the yarn detection unit.
The detection of the thread by means of its reflection of the introduced radiation also makes it possible to position the transmitter unit and the receiver unit in freely selectable regions depending on the reflection to be detected. Unlike the case of yarn detection by means of raster blocking, there is no need to position the transmitter unit and the receiver unit relative to each other on the bobbin.
Furthermore, the detection of the thread by means of radiation reflection has a high detection accuracy. Other reflections, such as those occurring at the transition from the transmitter unit to the outer tube wall and at the transition to the inner tube wall, can simply be shielded off by means of optical or electronic components.
The tube according to the invention is thus characterized by a high degree of reliability and accuracy in detecting the yarn placed in the tube. Furthermore, the yarn detection unit can be arranged on the bobbin in a very simple manner, since no access opening for inserting the transmitter unit and/or the receiver unit is required. The ability to freely position the yarn detecting unit also allows it to be located in the bobbin area which is subject to only minimal contamination during operation.
The electromagnetic radiation used for detection can be freely selected mainly depending on the material of the yarn to be detected and the material of the yarn tube. According to a particularly advantageous embodiment of the invention, however, the transmitter unit emits infrared radiation and the receiver unit is designed to receive infrared radiation.
The use of infrared radiation is distinguished by the fact that infrared radiation is particularly suitable for being injected into the interior of the bobbin by a transmitter unit arranged on the outside and for being received by a receiver unit arranged on the outside. Furthermore, infrared rays show good yarn reflection properties, so that a bobbin can be provided which has a yarn detection unit and which detects a yarn arranged within the bobbin particularly reliably.
The detection zone can be designed in a freely selectable manner, depending primarily on the electromagnetic radiation used, such that the electromagnetic radiation is emitted into the interior of the bobbin tube by the yarn detection unit arranged on the outside and the reflected radiation there is detected by the receiver unit arranged on the outside. However, according to a particularly advantageous embodiment of the invention, the tube is transparent to infrared radiation in the region of the yarn detection unit, in particular with a transparent design. In addition to the fact that the tube consists entirely of a material transparent to infrared radiation, this embodiment of the invention also offers the possibility of designing the tube to be infrared-transparent, in particular transparent or partially transparent to infrared radiation, only in the region in which infrared radiation is injected into the tube interior by the yarn detection unit and reflections are received. This embodiment is distinguished in particular by the fact that the bobbin can be designed independently of whether it is transparent to the infrared radiation required in the detection zone. The required bobbin permeability in the area of the yarn detection unit can be achieved, for example, by a suitable insert in the tube body or a multi-part bobbin, in which case the bobbin component with the detection zone has the required infrared ray permeability. The joining of the inserts or the assembly of the multi-part bobbin is done in such a way that the flow behaviour in the bobbin is not adversely affected.
The receiver units and transmitter units may be arranged in substantially any form. However, according to a particularly advantageous embodiment of the invention, they are arranged in a common housing of the thread detection unit. The corresponding embodiment of the invention allows the yarn detection unit to be mounted on the bobbin in an extremely simple and reliable manner, since the receiver unit and the transmitter unit do not need to be aligned, since they are already in place in a common housing in the manner required for operation. The use of a common housing thus increases the flexibility and detection reliability of possible applications of the yarn detection unit.
According to a particularly advantageous embodiment of the invention, the yarn detection unit extends outside the tube over an angle range of 5 ° to 50 °, preferably 5 ° to 40 °, particularly preferably 5 ° to 30 °. According to this embodiment of the invention, the yarn detecting unit extends over only a small arc length outside the tube. This allows a very compact design of the yarn detection unit and bobbin. At the same time, only a small part of the bobbin will adversely affect the measurement result due to contamination, since the positions of the transmitter unit and the receiver unit are within the above-mentioned angular range. In this connection, the compact design of the yarn detection unit offers the possibility of being positioned in a bobbin portion which is only slightly contaminated or hardly contaminated at all.
The yarn detecting unit can basically be attached to the outside of the tube in any way, for example by using screws or a suitable glue. According to a particularly advantageous embodiment of the invention, however, the yarn detection unit is attached to the outside of the bobbin by means of a tensioning mechanism. The tensioning mechanism comprises, for example, an elastic strap or belt in the form of a cable tie, whereby the yarn detecting unit can be fastened to any point of the bobbin in a simple manner. The cable ties also allow for easy removal and repositioning of the yarn detection unit by breaking and using additional cable ties.
The arrangement of the receiver unit and the transmitter unit relative to each other may depend mainly on the design specifications and the expected reflections resulting in particular from the position occupied by the yarn within the bobbin. This allows the receiver unit and the transmitter unit to be aligned parallel next to each other or to be oriented obliquely with respect to each other, for example in the direction of the bobbin axis.
A second aspect of the invention relates to a textile machine for producing wound bobbins, having a bobbin tube which comprises a yarn inlet, a connection for a vacuum source and a detection zone which is designed for monitoring the interior of the bobbin tube by means of a yarn detection unit arranged on the outside of the bobbin tube.
The textile machine is characterized in that at least one bobbin is designed according to one of the above-described embodiments.
This allows the advantages and effects described hereinabove with respect to this to be obtained.

Detailed Description
Fig. 1 is a schematic illustration of a winding unit 1 of a textile machine for producing cross-wound bobbins 3. During normal operation of the textile machine, the thread 21 is moved from a winding bobbin (not shown here) or a spinning device along the thread path 2 to a winding bobbin in the form of a cross-wound bobbin 3.
In the operating state shown in fig. 1, however, the thread path 2 is interrupted by an intentional or unintentional thread 21 breaking. In the case of yarn defect removal, the process is interrupted in order to remove defective yarn sections. If the thread section has already been run onto the cross-wound bobbin 3, the thread 21 must be unwound until the thread defect is completely removed from the thread 21 by appropriate cutting.
In the illustration shown in fig. 1, the cross-wound bobbin 3 is lowered to the winding roller 4. The cross-wound bobbin 3 is held by a bobbin holder 5, which is mounted at a rotary joint 6 (only schematically shown here) in a frame 7. The operation of the drive mechanism (not shown here) of the bobbin holder 5 is controlled by a control unit 8 by means of a line 9. The winding roller 4 is driven by a drive mechanism (not shown here) which is also connected to the control unit 8 by means of a wire 10. In order to unwind a defective yarn section, the winding roller 4 is driven in the direction 11 opposite to the winding direction, so that it also drives the cross-wound bobbin 3 with its circumferential surface against the circumferential surface 12 of the cross-wound bobbin 3 in the direction 13 opposite to the winding direction.
The suction nozzle 15 of the suction nozzle 14 is located in the region of the circumferential surface 12 of the cross-wound bobbin 3. The suction nozzle 14 is pivotally coupled to the frame 7 at a rotary joint 16, the connection to a central suction channel 18 of the vacuum source of the textile machine being produced in the rotary joint 16 by means of a bobbin 17. The suction nozzle 14 is pivoted by a drive mechanism (not shown here) which is connected to the control unit 8 via a control line 19. The valve (not shown here) is also controlled by the control unit 8, as a result of which the bobbin 17 is exposed to the action of the vacuum from the suction channel 18. The thread end 21 on the circumferential surface 12 of the cross-wound bobbin 3 is sucked into the suction nozzle 14 by a suction flow which is applied in the direction 20 of the suction channel 18 at the suction nozzle mouth 15.
In the operating state shown in fig. 1, the thread end 21 has been placed in the bobbin 17 in the region of a thread detection unit 22 arranged on the outside of the bobbin 17. In the area of the thread detection unit 22, a thread 21 is detected by the unit and is transmitted to the control unit 8 via a line 23.
When the end of the thread 21 has reached the thread detection unit 22, it is checked whether the end of the thread 21 has now been unwound from the cross-wound bobbin 3 so that the thread defect detected by the clearer has already been unwound from the cross-wound bobbin 3. If this is the case, the unwinding and suction of the yarn end 21 is stopped. The end of the yarn 21 is held within the suction nozzle 14 by vacuum. When the suction nozzle 14 is pivoted downwards, the cross-wound bobbin 3 performs a certain rotation in the direction opposite to the winding direction 13, whereby a length of wound yarn is again unwound from the cross-wound bobbin 3, so that the end 21 of the yarn can maintain its position in the suction nozzle 14.
Fig. 2 is a perspective view of the bobbin 17 together with the housing 24 of the yarn detecting unit 22 arranged on the bobbin 17. The housing 24 of the yarn detection unit 22 has two central openings 25, 26 facing the outside of the bobbin 17 for arranging the transmitter and receiver units (not shown here) of the yarn detection unit 22 fixed in place in the housing 24. An opening 29 in the housing 24 is provided for receiving the wires 23, whereby the transmitter unit and the receiver unit can be connected to the control unit 8.
In order to attach the housing 24 of the yarn detection unit 22 to the bobbin 17, the housing 24 has two attachment frames 27 projecting laterally from the housing, which attachment frames have an arc-shape adapted to the outer diameter of the tube. For attaching the housing 24, the attachment frame 27 has a plurality of openings 28 opposite each other, which are adapted to accommodate cable ties (not shown here), whereby the yarn detection unit 22 can be attached to the outside of the bobbin 17 in a simple manner.
