Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cloth spreading machines, in particular to an automatic cloth spreading machine automatic cloth identification and stopping device. Background Art
[0002] At present, there is no automatic stop device for the second-place cloth on the automatic spreading machines on the market, whether domestically or abroad. The existing automatic spreading machines will not stop automatically when spreading at the second-place cloth point. It all depends on the spreading worker to see the second-place cloth point and manually pull the brake line to stop the automatic spreading machine. Because the machine moves relatively fast, there will be a lag from the time the spreading worker sees the second-place cloth point and manually pulls the brake line. Often, the machine will exceed the second-place cloth point by a considerable distance from the time the second-place cloth point is discovered to the time the machine stops. After exceeding the distance, the machine must be manually operated to return to the second-place cloth point and the fabric at the second-place cloth point must be cut off before continuing to spread the cloth, which is time-consuming and laborious.
[0003] Because it is impossible to keep your eyes on the fabric all the time, sometimes you will miss the inferior fabric points and put the inferior fabric in, causing the finished product to become defective, affecting the quality of the finished product and causing economic losses. Utility Model Content
[0004] In order to make up for the above deficiencies, the present invention provides an automatic cloth-laying machine automatic cloth identification and stopping device that overcomes the above technical problems or at least partially solves the above problems.
[0005] The utility model is achieved in this way:
[0006] The utility model provides an automatic cloth-laying machine automatic cloth-splitting automatic identification and stopping device, comprising a power switch, one end of the power switch being provided with an input power switch, the other end of the power switch being provided with an optical fiber amplifier, one end of the optical fiber amplifier being provided with an optical fiber sensor, one end of the optical fiber sensor being provided with a wrapping wire, the wrapping wire being provided with a blue wire, a black wire, and a brown wire, and the other end of the power switch being provided with an intermediate relay. The other end of the power switch is electrically connected to one end of the intermediate relay, the blue wire is electrically connected to the negative pole of the input power switch, and the black wire is connected to the other end of the intermediate relay.
[0007] In one embodiment of the present invention, the optical fiber sensor and the optical fiber amplifier are electrically connected, and the optical fiber sensor is arranged below the opposite side electric eye.
[0008] In one embodiment of the present invention, the normally closed end of the intermediate relay is connected in series with the normally closed line on the stop button on the automatic spreading machine.
[0009] In one embodiment of the present invention, the blue wire, the black wire and the brown wire are all electrically connected to the optical fiber amplifier.
[0010] In one embodiment of the present invention, a fiber optic mounting bracket is provided on the top of the fiber optic amplifier, an inner bracket is provided inside the fiber optic mounting bracket, and a round hole is provided at the front of the fiber optic mounting bracket.
[0011] In one embodiment of the present invention, one end of the power switch is electrically connected to the positive pole of the input power switch, and the other end of the power switch is also connected to the brown line of the optical fiber amplifier.
[0012] The utility model provides an automatic cloth-spreading machine automatic cloth identification and stopping device, and its beneficial effects include:
[0013] 1. By setting up fiber optic sensors, when the automatic spreading machine spreads cloth to a place with a defective cloth point, the spreading machine automatically stops spreading. The spreading personnel only need to cut the defective cloth and then continue spreading. This avoids the disadvantage of relying entirely on the spreading workers to see the defective cloth point and manually pulling the brake line to stop the automatic spreading machine, thereby improving the spreading accuracy and work efficiency.
[0014] 2. By setting up a fiber optic amplifier, a diffuse reflection fiber optic sensor is installed under the electric eye of the opposite edge of the automatic spreading machine. The diffuse reflection fiber optic sensor is connected to the fiber optic amplifier, and the output end of the fiber optic amplifier is connected to the intermediate relay. The intermediate relay is connected to the stop button on the automatic spreading machine or the switch on the brake line. When the label paper or the knife edge at the edge of the secondary spreading point passes through the diffuse reflection fiber optic sensor, the fiber optic amplifier receives the signal and responds to control the intermediate relay to control the automatic spreading machine to stop spreading. Wait until the spreading personnel cuts the secondary cloth before continuing to spread the cloth, thereby improving the spreading accuracy and work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example
[0022] Reference Figures 1-4 This technical solution provides a device for automatically identifying and stopping defective fabrics on an automatic spreading machine, comprising a power switch 1, one end of which is provided with an input power switch 101, and the other end of which is provided with a fiber optic amplifier 2. One end of the fiber optic amplifier 2 is provided with a fiber optic sensor 3, one end of which is provided with a wrapping wire 304. Wrapping wire 304 includes a blue wire 301, a black wire 302, and a brown wire 303. An intermediate relay 4 is provided on the other end of the power switch 1. The other end of the power switch 1 is electrically connected to one end of the intermediate relay 4, the blue wire 301 is electrically connected to the negative terminal of the input power switch 101, and the black wire 302 is connected to the other end of the intermediate relay 4. By providing the fiber optic sensor 3, the automatic spreading machine automatically stops when it reaches a defective fabric point. The spreading operator only needs to cut the defective fabric and then continue spreading. This avoids the drawback of the spreading operator manually stopping the automatic spreading machine by visually observing the defective fabric point and pulling the brake line, thereby improving spreading accuracy and work efficiency.
[0023] Reference Figures 1-4Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that the optical fiber sensor 3 and the optical fiber amplifier 2 are electrically connected. The optical fiber sensor 3 is arranged below the opposite-edge electric eye. By setting the optical fiber amplifier 2, a diffuse reflection optical fiber sensor 3 is installed below the opposite-edge electric eye of the automatic spreading machine. The diffuse reflection optical fiber sensor 3 is connected to the optical fiber amplifier 2. The output end of the optical fiber amplifier 2 is connected to the intermediate relay 4. The intermediate relay 4 is connected to the stop button on the automatic spreading machine or the switch on the brake line. When the label paper or the knife edge at the edge of the secondary spreading point passes through the diffuse reflection optical fiber sensor 3, the optical fiber amplifier 2 receives the signal and reacts to control the intermediate relay 4 to control the automatic spreading machine to stop spreading. Wait until the spreading personnel cuts the secondary cloth before continuing to spread the cloth, thereby improving the spreading accuracy and work efficiency.
[0024] Reference Figures 1-4 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that the normally closed end of the intermediate relay 4 is connected in series with the normally closed line on the stop button on the automatic spreading machine.
[0025] Reference Figures 1-4 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the blue line 301 , the black line 302 and the brown line 303 are all electrically connected to the optical fiber amplifier 2 .
[0026] Reference Figures 1-4 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a fiber optic mounting bracket 201 is provided on the top of the fiber optic amplifier 2, an inner bracket 202 is provided inside the fiber optic mounting bracket 201, and a circular hole 203 is opened at the front of the fiber optic mounting bracket 201.
[0027] Reference Figures 1-4 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that one end of the power switch 1 is electrically connected to the positive pole of the input power switch 101, and the other end of the power switch 1 is simultaneously connected to the brown line 303 of the optical fiber amplifier 2. The diffuse reflection optical fiber sensor 3 of the automatic stop device of the automatic spreading machine is installed below the opposite edge electric eye. This can ensure that the sticker or the knife edge will not deviate from the diffuse reflection optical fiber sensor 3, ensuring stable detection.
[0028] Specifically, the working process or working principle of the automatic cloth-laying machine automatic cloth identification and stopping device is as follows:
[0029] Working principle 1. The power supply adopts 24V power supply to ensure personal safety. The source switch can control whether to activate the use of this device, which is more flexible to meet different usage requirements. The intermediate relay 4 is installed on the automatic spreading machine for easy wiring. The diffuse reflection optical fiber line and the optical amplifier are installed on the stainless steel bracket. The wiring is simpler and more convenient, the integrity is stronger and the use is more stable. The optical fiber amplifier 2 can also be installed in other places of the spreading machine. It adopts a multi-functional intelligent Chinese display optical fiber amplifier 2 to meet the needs of users with different needs. According to actual needs, the corresponding specific functions are used, such as normally open / normally closed / NPN / PNP / response speed / delay mode, counter function, frequency display function. When the actual detected value is greater than the set threshold, the sensor will turn on the output black line 302, otherwise it will turn off the output. The threshold can be adjusted by pressing the button, or by SET Automatic Calibration: This method is suitable for most scenarios. Even when the device is running, sensitivity can be easily set by moving the workpiece. The device can be stopped and the fiber head can be aligned with the area to be inspected. On the numerical display, press and hold the Set button for more than 3 seconds. When "AutoCalibration" appears on the screen, release the Set button to complete the setting.
[0030] Working principle 2: one end of the power switch 1 is connected to the power + pole and the other end is connected to the brown wire 303 of the optical fiber amplifier 2, that is, 24V power is provided to the optical fiber amplifier 2. At the same time, it is also connected to one end of the coil of the intermediate relay 4, that is, 24V power is provided to the intermediate relay 4. The blue wire 301 of the optical fiber amplifier 2 is connected to the 24V power - pole; the black wire 302 of the optical fiber amplifier 2 is connected to the other end of the coil of the intermediate relay 4, the optical fiber sensor 3 is connected to the optical fiber amplifier 2, and the normally closed end of the intermediate relay 4 is connected in series with the normally closed wire on the stop button on the automatic spreading machine, and can also be connected in series with the normally closed end of the travel switch on the brake line. When the optical fiber amplifier 2 outputs a signal, it drives the intermediate relay 4 to work, so that the normally closed intermediate relay 4 is converted to open, thereby driving the automatic spreading machine to stop spreading.
