Definitions
- the invention relates to a thread delivery device which in the preamble of claim 1 specified type.
- a thread delivery device with such a sensor device is from the operating and Maintenance instructions IWF 9 007, IWF 9 107, IWF 9 207 from IRO AB, with the reference number 07-8930-0812-01 / 9647, pp. 10, 43, 44, 50, 51 and 53.
- the Sensor device are two sensor arms one above the other and arranged such that their feeler feet the thread supply on two in the feed direction of the thread turns places in succession on the storage drum for presence or absence scan.
- Each sensor arm is designed as a two-legged wire bracket, whose cranked sensor base protrudes downwards from the sensor housing.
- the invention has for its object a yarn delivery device of the aforementioned To create kind that by a compact sensor device with few Individual parts and a precise, yet insensitive response distinguished. This task is for a thread delivery device with only one sensor arm as well as with several sensor arms.
- the scanning device for the respective sensor arm and also the spring arrangement, which acts on the sensor arm in the direction of its basic position, on the same Side of the bearing are integrated into the sensor housing like the sensor foot supporting feeler arm part, becomes more significant in the direction of the axis of the storage drum Construction space saved. Furthermore, the number of individual parts required is reduced the sensor device noticeable. Transversely to the axis of the storage drum is also Space is saved because the individual, cooperating parts are arranged closely together to let. This is particularly advantageous if the sensor device has several Sensor arms and a corresponding number of accessories. thanks The compact arrangement prevents harmful vibrations, so that a stable and sensitive response can be achieved.
- the number of items can be in a small space according to claim 2 reduce that each feeler arm part directly with its sensing device and spring assembly cooperates, i.e. without the need for additional motion-transmitting Accessories.
- the sensor arm part is already with the actuator and the stop trained to work with his scanner and spring assembly needed. This has manufacturing advantages.
- the emergence of harmful parasitic is structurally simple Avoided vibrations that could influence the response behavior.
- the spring element does not only have the task, regardless of the installation position the thread delivery device the load on the sensor arm in the direction of its basic position to generate, but in addition and without any significant additional construction work the development of oscillating oscillating movements of the sensor arm under unfavorable Operating states, if necessary, to dampen as they arise. Is achieved this is achieved by spring hardening in a range of motion that is dependent on the stroke of the sensor arm, in which it is outside the actual scanning the presence or absence of the thread supply due to the work dynamics can. The resulting damping prevents an undesirable rocking effect, without working the sensor arm when sensing presence or absence of the thread. Conversely, this damping effect improves the correct working of the sensor arm within its actual working area. This damping effect is also advantageous if the respective scanning device on the the sensor foot facing away from the storage is provided.
- the suspension of the sensor arm and the aforementioned Damping accomplished in a structurally simple manner.
- the onset of damping can be adjusted as required, expediently from an easily accessible location outside the sensor housing.
- an optodetector is used for scanning which is high Operational safety is inexpensive and works precisely.
- the optodetector can be in place the compact sensor device protected.
- an optodetector is only one way to pick up the working movements of the sensor arm.
- a contactless inductive, electrical or electromagnetic, pneumatic detector or a contact-sensitive switch can be used.
- the output signals of the scanning device are advantageously used for Control of the drive of the thread delivery device or for error monitoring in the thread delivery device or a thread processing system, of which the thread delivery device is a component.
- the actuator of the scanning device is integrated in the sensor arm part. It takes on an additional function by changing the end position of the sensor arm part certainly.
- a very clean signal transition of the scanning device achieved in a structurally simple manner because the cover edge with the cover surface can overlap, and then reliably interrupts the beam path.
- Cooperation between the cover edge and the cover surface creates with others Words a quick transition between full shade and none at all Shading of the beam path, which simplifies the signal evaluation and the electronic effort required for signal evaluation can be reduced.
- This scissor-like cutting and releasing the beam path is also useful if the scanning device is not on the side of the sensor foot, but on the side of the bearing of the sensor arm facing away from the sensor foot is provided.
- the aforementioned goal is structurally particularly simple reached.
- the response behavior of the sensor device is thereby improved that the guide arm part in the guided guide fork or at least against lateral evasive movements is supported. In this way, lateral vibrations of the Steam off the guide arm part as it arises.
- the optodetector is favorable in terms of production and assembly technology with its holder on a board e.g. in the sensor housing or on another Control board arranged.
- the board can take on an additional function by it forms a cover of the inside of the sensor housing to the outside and possibly even serves as a stroke limiter for the sensor arm.
- the passage opening for the sensor base can be small, so that dirt hardly penetrates or simple additional measures are sufficient to prevent the ingress of dirt to avoid reliably.
- the sensing arm part is a plastic molded part, who sits on the axis forming the bearing and relative to it is pivotable.
- the sensor foot is only inserted into and in the jack positioned, appropriately adjustable, so that the basic position of the sensor arm can be accomplished solely by adjusting the sensor base in the socket. This principle is also useful if the scanning device on the Sensor foot facing away from the storage is provided.
- a sensor device with at least two sensor arms the number of individual parts and the installation space reduced because all sensor arms have one have common axis, and because the spring elements or the only all Spring element acting on sensor arms can be accommodated in a space-saving manner. It is it is important if the switching device for damping no other components needed because the same spring element is used for the damping function, which is also used for the loading of the sensor arm towards its basic position is.
- a common axis or shaft is particularly advantageous whenever if the sensor device contains a plurality of sensor arms which hold the thread at different points Scan the positions of the storage drum regardless of how the scanning device is designed and / or whether the scanning devices are attached on the side of the sensor feet or on the other side of the common axis.
- the sensor feet are identical molded parts made of metal. This is favorable in terms of production technology, because it is used for different functions Sensor arms of the same sensor device, the same sensor foot can be used.
- the continuous surface of the feeler foot, with which it rests on the thread, prevents extraordinarily effective that feared in the form of open stirrups with conventional feeler feet Collecting contaminants such as lint. This is especially so important if the feeler foot belongs to a so-called thread break sensor, which on The winding end of the thread supply rests practically permanently on the thread supply and does not make evasive movements with them during normal operation he could lose collected fluff or a fluff tail.
