Definitions
- the invention relates to a thread delivery device which in the preamble of claim 1 specified type.
- the invention has for its object a yarn delivery device of the aforementioned Type to create, which is characterized by a compact sensor device with a precise and insensitive responsiveness.
- the projection covers the scanning distance not only by one-way movement from one side, but the projection also works with the Cover area together, that the scanning distance first from the cover area the side opposite the penetration side of the projection into the scanning path is exactly limited, and when the projection passes through the scanning path finally the overlap between the cover edge and the cover surface is established is that a quick and complete coverage of the scanning distance with a sharp transition.
- the scanning path is, so to speak, two opposite ones Sides narrowed here (in the manner of a slit diaphragm) and ultimately completely interrupted. It is structurally simply a clean signal transition Scanning device achieved when the cover edge overlaps the cover surface and reliably interrupts the scanning path.
- the flag is an actuator of the scanning device in the sensor arm or integrated sensor arm part. It can perform an additional function if it determines the end position with the stop.
- the stroke shapes simple at the same time on the cover surface.
- the overlap is narrow transversely to the direction of the sensor arm Space.
- the flag serves as a carrier of the lead and assists the coverage of the scanning distance.
- the scanning distance is particularly simple and effectively limited and blocked.
- optodetector For scanning is preferred according to claim 5 in a fork-shaped holder housed optodetector used, which is inexpensive with high operational reliability is and works precisely.
- the optodetector can be placed protected.
- optodetector is only one way of tapping the movements of the Feeler. It could also be an inductive, an electrical, or an electromagnetic or a pneumatic detector can be used.
- Output signals from the scanner are expedient for controlling the drive of the thread delivery device or for error monitoring of the thread delivery device or a thread processing system used to which the thread delivery device belongs.
- the bracket of the Optodetector can be arranged on a circuit board in the sensor housing, the PCB acts as a cover inside the sensor housing to the outside. Possibly even forms a stroke limiter for the sensor arm.
- One for the feeler foot The passage opening provided can be small, so that dirt can hardly penetrate or simple measures are sufficient to prevent the ingress of dirt to avoid reliably.
- the spring element has the task of loading regardless of the installation position of the thread delivery device to generate the sensor arm to the basic position, and in addition the emergence of swinging movements of the sensor arm under unfavorable operating conditions steam, if necessary as soon as they arise. This is achieved through a spring hardening in a movement range of the sensor arm into which he can get due to his work dynamics.
- the forced Damping prevents an undesirable rocking effect without the work of the Affect sensor arms. Conversely, damping improves correct working of the feeler arm when sensing the presence or absence of the thread.
- the suspension of the sensor arm and the aforementioned Damping accomplished in a structurally simple manner.
- the response behavior of the sensor device is improved, if the guide arm is in the stationary guide fork in unfavorable operating conditions guided or at least supported against lateral evasive movements becomes. Lateral vibrations of the guide arm can already be created dampen.
