Embodiment Construction

[0022] For example, figure 1 Shown is a machine ring 1 associated with a circular knitting machine, on which a plurality of yarn sensor units 2, all substantially identical, are fixed. These yarn sensor units are connected to each other and to the main control unit 3 via a bus not specifically shown in the figure, whereby said main control unit can likewise be fixed on the machine ring 1 . The yarn sensor unit 2 is provided to monitor: whether there is a yarn moving through or whether the current yarn is moving or has stopped. figure 1 Such a yarn 4 is shown connected to one of the yarn sensor units 2 .

[0023] Each yarn sensor unit 2 comprises a holder 5 which can be locked onto the machine ring 1 at one end. In particular, it is obvious from figure 2 It can be seen in the figure that the retainer 5 may be provided with two, preferably slightly elastic, detent fingers 6, 7 for receiving the machine ring 1 therebetween so that the machine ring is locked in place.

Abstract

The invention relates to a thread sensor unit (2) designed as a modular system that comprises, in addition to a holder (5) that may be selectively connected to a wide variety of thread guiding elements (16 to 16c, 17 to 17c), a compartment of a thread sensor (9). Said sensor has elements disposed one behind the other in the longitudinal direction of the thread for transmitting and receiving electromagnetic radiation (light). The elements have optical axes (37, 38) inclined toward one another that preferably lie in a common, preferably vertical plane with the thread (4).

Description

technical field [0001] The invention relates to a yarn sensor unit for use on a textile processing device, such as a knitting machine. Background technique [0002] In practice, it is required to be able to constantly detect whether the yarn traveling to the yarn consumption point is moving or has stopped. However, such sensors do not provide signals of other characteristics. Additionally, it may be necessary to find out conditions such as yarn speed. Accordingly, a wide variety of sensor systems have been developed in relation to the yarns used in the textile process. [0003] For example, document DD 243 518 A1 discloses an optoelectronic device based on the principle of reflective gratings for detecting defects present in textile structures and, in another alternative, individual yarns. For this purpose, the sensor is designed as a transmission grating. [0004] Document DE 195 25 260 A1 shows a photoelectric control device for a weft thread measuring and storage devi...
