Description

Technical Field

[0001] The invention relates to the technical field of high-speed camera devices, and in particular to a high-speed camera device for monitoring yarns in a textile machine. Background Art

[0002] A textile machine is a commonly used device in textile work. There are many types of it, and a water jet loom is one of them. At present, when a water jet loom is working, the weft thread passes through the end of the weft nozzle of the loom body and is brought out by high-pressure water flow. A device called a weft feeler is installed on the other side of the textile machine. The weft feeler uses infrared fiber optic sensing to detect whether the weft thread is ejected normally, thereby controlling whether the textile machine is shut down. When the yarn passes through the weft feeler, the weft thread interrupts the continuous infrared rays between the probes of the weft feeler, thereby judging that the weft thread is ejected normally. Although this monitoring method is simple, it still has the following problems:

[0003] 1. Since the working environment of the water jet loom is humid and impurities such as fiber debris are easily mixed in the circulating water, these foreign objects will also cause abnormal blocking of the infrared beam when flowing through the detection area of ​​the weft feeler, causing the control system to misjudge and trigger unnecessary shutdown;

[0004] 2. Generally, the weft thread will be cut off at the tail end of the weft thread after it passes through the weft feeler for a certain distance. At the same time, the head end of the weft thread that passes through the weft feeler for a certain distance will also be cut off, which will cause the weft thread head of this distance to be wasted.

[0005] In summary, there is a need for a high-speed camera device that can monitor and judge accurately and stably. Summary of the invention

[0041] Embodiment 1

[0042] To solve the technical problems in the background art, the following high-speed camera device for monitoring yarns of a textile machine is provided:

A patrol camera assembly 7 is connected between the driving assemblies 3, a spray line camera mechanism 5 is rotatably connected to the front wall of the first fixed plate 2, two groups of spray line camera mechanisms 5 are mirrored about the vertical center line of the first fixed plate 2, the spray line camera mechanism 5 is provided with a camera structure and a blocking structure, a blocking mechanism 6 is connected to the front wall of the first fixed plate 2, thread combing assemblies 9 are provided on the inner walls on both sides of the feeding table 4, and accompanying water removal assemblies 8 are arranged across the inner walls on both sides of the feeding table 4, and the spray line camera mechanism 5 and the patrol camera assembly 7 are flipped by the driving assembly 3 and have two states;

[0044] In the first state, the patrol camera assembly 7 is turned downward and arranged inside the feeding platform 4, and one side of the patrol camera assembly 7 is turned downward and plugged into the accompanying water removal assembly 8, so that one side of the accompanying water removal assembly 8 moves and works synchronously with the patrol camera assembly 7, and the spray line camera mechanism 5 is turned downward, and the camera structure is positioned by the blocking mechanism 6 and is located on the same horizontal line as the end of the weft nozzle of the loom body 1;

At the same time, the patrol camera assembly 7 is used on the feeding table 4 to patrol and monitor the state of the woven yarn surface. When the weft yarn spray state at the nozzle position is abnormal or the yarn surface state is abnormal, the driving assembly 3 synchronously drives the spray line camera mechanism 5 and the patrol camera assembly 7 to flip, so as to cut off the weft yarn in time and stop the machine, thereby reducing the waste of the weft yarn head end and the idle stop failure time, and the monitoring and judgment of abnormalities are more accurate and stable;

[0048] 2. When the spray line camera mechanism 5 is working in the two states of flipping, the blocking mechanism 6 is used to fit and position, so as to ensure that the camera structure and the blocking structure of the spray line camera mechanism 5 are aligned with the end of the weft yarn nozzle of the loom body 1, thereby improving the stability of the weft yarn head monitoring and blocking;

[0077] Press first Figure 1-Figure 12The first motor 31 is started to drive the first rotating shaft 32 to rotate, and the patrol camera assembly 7 is turned down as a whole to be close to the inner bottom surface of the conveying platform. The push block 741 on the electric slider 74 is inserted into the push plate 87, the second camera 76 is turned on and the electric slider 74 is started. At the same time, the first rotating shaft 32 drives the first gear 33 to rotate, drives the first tooth plate 36 to rise, and the first tooth plate 36 drives the second gear 54 to rotate, so that the water spray camera mechanism is turned over as a whole to be close to the weft nozzle on the loom body 1, so that the first camera 56 and the weft nozzle of the loom body 1 are at the same height, wherein the flat push plate 61 and the back plate 551 are kept in contact with each other to ensure the shooting direction of the first camera 56, the first camera 56, the lighting lamp 557, the infrared sensor 553 and the air pump 5541 are turned on for monitoring, and the first jet ring 5542 and the second jet ring 5543 spray air to form an air curtain at the position of the first camera 56 to block water mist and dust, thereby improving the monitoring stability of the first camera 56;

[0078] The weft yarn nozzle on the loom body 1 sprays the weft yarn, and the weft yarn passes between the second fixed plate 552 and the third fixed plate 555. At the moment of spraying, the first camera 56 is used to shoot the spraying state of the end of the weft yarn, and at the same time, the electric slider 74 drives the second camera 76 to move back and forth to shoot the textile yarn surface. When the second camera 76 moves to the side position of the yarn surface, the second camera 76 pushes the push plate 97 to drive the combing plate 963 to flip and comb the thread ends on the side of the yarn surface. At the same time, the push block 741 on the electric slider 74 pushes the push plate 87 to start the negative pressure pump 83, so that the pumping plate 86 moves back and forth to extract the moisture on the yarn surface, thereby improving the monitoring stability of the second camera 76;

[0079] When the first camera 56 monitors an abnormal state of the weft yarn end being sprayed out or the second camera 76 monitors an abnormal state of the yarn surface, the first motor 31 is started to drive the spray line camera mechanism 5 and the patrol camera assembly 7 to flip upward as a whole, and the line blocking plate 556 is blocked at the weft yarn nozzle position on the loom body 1, and the weft yarn spraying is stopped immediately, which has the high efficiency of stopping the machine when an abnormal state is detected.
