Description
Technical Field
The utility model relates to a detection mechanism, in particular to detection of a yarn replacement in the yarn replacement process of textile industry.
Background
In textile mills, spinning machines used in spinning mills, spindle replacement is needed, and in the traditional textile mill, manual yarn replacement is adopted, and the common mode is that in the prior art, manual detection is generally adopted. With the development of economy and the progress of science and technology, artificial intelligence is gradually applied to factories. In the prior art, a weighing system is mostly adopted for yarn replacement alarming, namely, when one spindle is used up, the weight sensor is used for alarming. This way of warning gives a certain effect, but because of the problem of the price of the weight sensor and the problem of the false alarm rate, in particular it is necessary to delay the warning, i.e. the warning is not immediately after the yarn has been used up, because, in order to ensure a certain accuracy, it is necessary to continue the warning for a certain time at one weight sensor, and such a system often generates redundant data, because of the need to detect the result of the weight sensor without interruption. Therefore, there is considerable system redundancy data. Another approach in the market is to use a vision system for detection, which is more costly, and since the profit margin of the weaving industry itself is not high, such a way is generally not adopted, and only exists in the patent literature.
Disclosure of Invention
In order to solve the technical problems, the utility model provides a yarn detection mechanism, which directly detects yarns, namely detects a connecting line between two wire ingots, and adopts a trigger type detection mode. The sensor is triggered at the instant the spindle is used.
A yarn detection mechanism is arranged on a creel, and a hanging rod for installing a spindle is arranged on the creel; the spindle is arranged on the hanging rod; the method is characterized in that: the wiring between the two spindles passes through the yarn detection mechanism; the yarn detection mechanism is connected with the control system; the connecting line between the two spindles is contacted with the elastic sheet of the detection mechanism, the elastic sheet is connected with the sensor in a matched manner, the yarn is arranged below or above the elastic sheet of the yarn detection mechanism, when one of the spindles is used up, the yarn is tensioned, the elastic sheet is sprung or pressed down, and the sensor in yarn detection is started; the sensor signals the control system.
The background of the design needs to be explained here. I.e. on a loom, the spindles of which are present in a pair-to-pair. The head wire of the first spindle is connected with a loom; the tail wire of the first yarn is connected with the head wire of the second spindle; when the wire is connected, the connecting wire between the two wires passes through the yarn detection mechanism, and the connection between the two wires is kept loose; when the first winding spindle is used up, the yarn is tensioned instantaneously, and the yarn is tensioned to spring the spring plate, so that the inductor is triggered; in order to ensure that the spring must be sprung, it is often required that the thread attached to the loom is higher than the thread below the detection means, which is also desirable when the device is installed, since only then can the tensioned thread be lifted or pushed down and thus triggered. By adopting the scheme, the control system does not need to detect all the time, and only needs to wait for triggering. The system programming and control becomes very simple and the accuracy is improved. Note that manual operation is adopted in the design of the utility model because the robot cannot complete knotting or the cost of completing wire connection knotting is high. When the first spindle is used up, an alarm is triggered, and the next spindle is manually installed. And then the tail wire of the second spindle is connected with the head wire of the spindle which is just installed, and the connecting wire passes through the lower part of the elastic piece of the detection mechanism. The connection is now kept in a relaxed state. And so forth.
The technical scheme is further improved, and the yarn detection mechanism consists of a shell, a mounting hole, an electronic detection plate and an elastic sheet; the shell is provided with a transmitting port and a receiving port; the elastic sheet covers the transmitting port and the receiving port; the elastic sheet is movably arranged on the shell, and the wiring penetrates through the elastic sheet from the lower part; when the wiring is tensioned, the elastic sheet is opened, the transmitting port and the receiving port are opened, and the inductor is started to trigger. When the spring plate is installed, the spring plate can achieve the triggering effect through the position, the light sense or the strength and the like through the spring or the torsion spring or by utilizing the elasticity of the spring plate. Of course, the trigger should be immediately restored. After the ingot is loaded manually, the wire is connected again, and the wire is placed under the elastic sheet.
The technical scheme is further refined; the electronic detection board is a reflective photoelectric switch. The distance between the front end face of the reflective photoelectric switch and the reflector is kept within a prescribed range.
The reflective photoelectric switch must be installed inside the shell, so that strong light is prevented from directly irradiating.
The reflective photoelectric switch is adopted in the scheme, and aims at being low in cost, the design mode of the elastic sheet is that only a few pieces of hair are needed, the elastic sheet is needed to be used for blocking the photosensitive opening, and the third design is convenient, and the photosensitive and receiving can be integrated, so that the trigger is sensitive.

Detailed Description
In order to further describe the structural features of the present product, further description is provided below with reference to the accompanying drawings.
As shown in the figure, a yarn detecting mechanism is arranged on a creel, and a hanging rod for installing a spindle is arranged on the creel; the spindle is arranged on the hanging rod;yarn detecting mechanism is passed in wiring between two spindleThe method comprises the steps of carrying out a first treatment on the surface of the The yarn detection mechanism is connected with the control system; the specific structure of the detection mechanism is as follows: he consists of an elliptic shell, wherein an electronic detection plate is arranged in the shell; the electronic detection plate is a reflective photoelectric switch, a mounting hole is formed in the shell, the mounting hole needs to avoid the electronic detection plate, the electronic switch photosensitive opening is detected, the photosensitive opening is blocked by the elastic sheet, a wire passes through the lower part or the upper part of the elastic sheet, and the elastic sheet can achieve the triggering effect through the position, the light sensation or the strength by adopting a spring or a torsion spring or utilizing the elasticity of the elastic sheet.
The elastic sheet covers the transmitting port and the receiving port; the elastic sheet is movably arranged on the shell, and the wiring penetrates through the elastic sheet from the lower part; when the wiring is tensioned, the elastic sheet is opened, the transmitting port and the receiving port are opened, and the inductor is started to trigger.
The connecting line between the two spindles is contacted with the elastic piece of the detection mechanism, the yarn is placed under the elastic piece of the yarn detection mechanism, when the yarn is tensioned, the elastic piece is sprung up, and the sensor in the yarn detection is started; the sensor signals the control system. On a loom, its spindles appear in a pair-to-pair.
The specific working principle is as follows: the head wire of the first spindle is connected with a loom; the tail wire of the first yarn is connected with the head wire of the second spindle; when the wire is connected, the connecting wire between the two wires passes through the yarn detection mechanism, and the connection between the two wires is kept loose; when the first winding spindle is used up, the yarn is tensioned instantaneously and is higher than the elastic sheet of the detection mechanism, at the moment, the yarn is tensioned and bounces off the elastic sheet, and at the moment, the inductor is triggered. Of course, a down-pressing spring plate can be adopted, namely, the yarn is placed under the spring plate, and the tensioned yarn is lower than the detection mechanism during detection and installation; after tightening, the wire is pressed down, thereby changing the position of the spring. Thus, the control system does not need to detect all the time, and only needs to wait for triggering. The system programming and control becomes very simple and the accuracy is improved. Note that manual operation is adopted in the design of the utility model because the robot cannot complete knotting or the cost of completing wire connection knotting is high. When the first spindle is used up, an alarm is triggered, and the next spindle is manually installed. And then the tail wire of the second spindle is connected with the head wire of the spindle which is just installed, and the connecting wire passes through the lower part of the elastic piece of the detection mechanism. The connection is now kept in a relaxed state. And so forth.
