Description

Technical Field

[0001] The present invention relates to a ribbon walking machine with an on-line working condition monitoring function and a monitoring method thereof, belonging to the technical field of knitting machinery equipment. Background Art

[0002] Ribbon is an item with wide applications. It can be used as various shoelaces, elastic bands, high-tensile bands, sports bands, curtain bands, etc. The ribbon machine technology can also be used to manufacture industrial cables such as cables and wire ropes. However, the traditional knitting machine has a complex structure, resulting in a large volume of the knitting machine, occupying a large amount of factory space, and its knitting efficiency is low, making it difficult to improve production efficiency.

[0003] The ribbon walking machine, also called a high-speed rope and ribbon machine, compared with the traditional knitting machine, has multiple advantages such as high speed, quietness, small floor space, and low shutdown rate. It is suitable for knitting various round or flat non-elastic and elastic knitting ropes and ribbons, for manufacturing various daily-use ropes and ribbons, as well as various industrial cables.

[0004] However, as a knitting machine, the breakage of the silk thread is one of the main faults of the walking machine; on the other hand, after long-term use of the walking machine, each component will age to a certain extent, resulting in certain wear, deformation, and assembly position deviation, etc. If the abnormal working conditions cannot be detected in time and the relevant components are not replaced and maintained, it will cause the device to malfunction during use, resulting in low stability of the walking machine, large operating noise, shortened equipment life, and even unstable product quality. Whether it is the wire breakage fault or the abnormal working conditions caused by component aging, it is necessary to detect and identify them in time and accurately. The existing ribbon walking machine technology has a relatively low level of digitization and intelligence, lacking the comprehensive working condition monitoring technology for various working conditions during the operation of the walking machine, and a comprehensive on-line working condition monitoring technology for the operation of the walking machine needs to be developed.

The terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0023] The present invention discloses a weft knitting frame with an online working condition monitoring function, aiming to provide an online monitoring technology for the comprehensive working conditions of the existing knitting frame.

[0024] Figure 1 It is a schematic structural diagram of a weft knitting frame with an online working condition monitoring function according to Embodiment 1 of the present invention. Figure 1 The structure is shown, without including the frame and the data processing unit. Figure 1 In this figure, 1 is the panel of the wire guiding mechanism, 2 is the wire bundling mechanism, 21 is the wire bundling through hole, 3 is the wire guiding mechanism, 311 is the knitting spindle, 312 is the bobbin, 313 is the silk thread, 32 is the closed track, 41 is the wire detector, 42 is the spindle detector, and 5 is the detection surface. The detection surface is a hypothetical plane without physical structure; both the wire detector and the spindle detector are ultrasonic sensors using transceiver probes.

The wire guiding mechanism includes a closed track, 16 traversing spindles that can move along the closed track, and a wire bundling mechanism with a wire bundling through - hole. The inner surface of the through - hole of the wire bundling mechanism is a rotating surface. Each traversing spindle is threaded with a bobbin. Sixteen silk threads above the traversing spindles are bundled into one after passing through the wire bundling through - hole of the wire guiding mechanism in example 1; the wire guiding mechanism in example 1 is paired with a group of monitoring units composed of a wire sensor and a spindle sensor. The minimum circumscribed rectangle of the two detection surfaces of the two sensing probes contains a symmetry axis perpendicular to the wire guiding mechanism panel. The two symmetry axes and the central axis of the wire bundling through - hole are in the same plane, and this plane is perpendicular to the wire guiding mechanism panel, which is called the first detection plane; the minimum circumscribed rectangle of the two detection surfaces also has a symmetry axis perpendicular to the first detection plane; among the cross - sections where the first detection plane intersects with the closed track, the cross - section closest to the spindle sensor is called the first detection cross - section. During the time interval (t1, t2) when any traversing spindle passes through the first detection cross - section, for the wire sensor in example 1, the signal of the silk thread passing through the first detection plane is called the characteristic signal α, and the signal of the traversing spindle passing through the first detection cross - section detected by the spindle sensor is called the characteristic signal β.

[0026] For the technical solution of example 1, the further description is as follows:

[0027] 1) The detection surface of the sensor includes the emission surface of the emission probe, the receiving surface of the receiving probe, and the signal transceiver surface of the transceiver - integrated probe.

The central axis is perpendicular to the wire guiding mechanism panel. When the positions of the central axis and the two symmetry axes perpendicular to the wire guiding mechanism panel are determined, at most only one vertical plane with respect to the wire guiding mechanism panel can be determined; the statement "the minimum circumscribed rectangle of the two detection surfaces also has a symmetry axis perpendicular to the first detection plane" is used to limit the detection direction of the sensor. Another equivalent statement of this statement is: for a determined monitoring unit, there is a unique vertical plane with respect to the wire guiding mechanism panel, and this vertical plane can simultaneously contain the normal line of the center point of the rectangular surface surrounded by the minimum circumscribed rectangle of each sensor detection surface and the central axis of the wire bundling through - hole; each of the normal lines of the center points is perpendicular to the central axis of the wire bundling through - hole.

The minimum circumscribed rectangle of its detection surface has one axis of symmetry perpendicular to the wire mechanism panel (1) and the other axis of symmetry perpendicular to the first detection surface.

Figure 3 In: 81 is the transmitting probe of the ingot detector, and 82 is the receiving probe of the ingot detector. As Figure 3 shown, when the ingot sensor of the present invention includes one receiving probe and one transmitting probe, through the installation layout, it is certain to achieve that there is one and only one detection cross-section between the detection surfaces of the two transceiving probes; similarly, when the wire sensor of the present invention can also be two transceiving probes, through the installation layout, it is certain to achieve that there is at most one silk thread existing between the two transceiving probes at the same time.
