Problems solved by technology

In the prior art, worker monitoring is generally used, but artificial monitoring will result in inaccurate judgments or missed inspections; there are also monitoring through image acquisition devices, which are transmitted to identification devices to identify defects after image acquisition, and then generate real-time alarms
Due to the limitation of the structure, it is impossible to detect the defects of the weaving fabric through the cylinder wall during the weaving stage. The monitoring through the image acquisition device can only be detected during the winding stage of the weaving fabric, and the machine is always in high-speed motion during the weaving process. Therefore, the existing technology generally cannot collect images of the cloth in the weaving process, and it is not convenient for the image collection device to perform all-round monitoring of various positions.

Embodiment 1

[0041] The purpose of this application is to provide an image acquisition system for cloth detection on a circular loom. In a traditional circular loom, the traditional cloth image detection mode is changed to make detection more timely and accurate without affecting the original The overall structural setup of the circular loom.

[0042] like figure 1 As shown, in the existing circular loom, the spinning thread can be woven into a tubular cloth 2, the tubular cloth is pressed into a flat double-layered cloth by a flattening mechanism, and then wound by a winding roller 9, the existing In the technology, in order to detect cloth defects, an image acquisition device or sensor is generally set at the cloth in the winding stage, such as a camera or a camera to collect images. In addition, the image acquisition device or sensor and the cloth are generally kept relatively stationary, and one or more image acquisition devices or sensors are used to detect the defects of the cloth i...

Embodiment 2

[0070] In this embodiment, the present application can also realize the alternate lighting of the second lighting element 52 through another control method. Specifically, the transmitter 7 is controlled to send a control signal to the receiver 51 through wireless transmission, and the second lighting element 52 also in electrical connection with the electrical energy storage element;

[0071] The rotating cylinder 3 drives the receiver 51 to rotate together. When the receiver 51 rotates to the emission area of ​​the control transmitter 7, the receiver 51 receives the control signal for the control transmitter 7 to control the second lighting element 52 and the electrical energy storage. The element emits light when it is turned on.

[0072] Specifically, in this embodiment, the electric energy storage element can be a battery, which is installed on the rotating cylinder 3 and is relatively fixed and electrically connected to the second lighting element 52 , and the circuits of...

Embodiment 3

[0074] In this embodiment, mainly based on Embodiment 1, an image acquisition method for cloth detection on a circular loom is provided. Specifically, the image acquisition method includes but is not limited to image acquisition and processing. The above method is implemented based on an image acquisition system for the detection of cloth on a circular loom according to Embodiment 1, which may specifically include:

[0075] When the cloth rotates, keep the first lighting module continuously emitting light, and control the transmitter to send a control signal and / or power supply to the receiver through wireless transmission, so as to control the second lighting element to emit light or stop emitting light;

[0076] Controlling the image acquisition device to photograph the cloth at the frequency f;

[0077] transmitting the image captured by the image acquisition device to the image processing device;

[0078] Control the image processing device to analyze and identify the ima...

Abstract

The invention discloses an image acquisition system for cloth detection of a circular weaving machine. The image acquisition system comprises an image acquisition device, a fixed supporting device, a rotating cylinder, a first illumination module and a second illumination module, the first illumination module is arranged on the inner side of the cylindrical cloth and is fixed relative to the image acquisition device; the multiple second lighting modules are evenly distributed on the inner wall of the rotating cylinder and located between the cylindrical cloth and the rotating cylinder. And the height of the second illumination module is matched with that of the image acquisition device. By arranging the first illumination module and the plurality of second illumination modules at the corresponding positions, no matter which angle the tubular cloth rotates to, the tubular cloth has light irradiating from the inner side and the outer side, so that the cloth defect can be timely and accurately identified, and the identification efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the field of cloth detection, in particular to an image acquisition system for cloth detection of a circular loom. Background technique [0002] The textile machines in the prior art can be divided into horizontal textile machines and circular textile machines according to the textile method. The horizontal textile machines use horizontal textile methods for weaving. The horizontal loom has the advantages of easy weaving operation and simple weaving, but the textile output of the horizontal loom is small and the weaving efficiency is low. The circular loom uses the circular loom head wheel and the circular loom textile device to cooperate with each other for textile work, with high textile output, few processes, high fabric quality and good product adaptability. [0003] During the operation of the circular loom, it is necessary to observe the defects of the produced fabrics. Defects can include but are not limited to oil stai...
