Abstract
Description

[0001] The present application relates to the technical field of textile machinery, and in particular to a winding machine cradle control system and a winding machine. Background Art
[0002] Winding is the process of turning yarn or hank into a package that meets specific requirements on a winding machine. The key to winding technology lies in precisely controlling yarn tension and cradle pressure. Controlling cradle pressure can adjust the yarn winding density to a certain extent, improving the shape of the package.
[0003] When winding high-elastic filament yarn, it is difficult to control the shape and density of the high-elastic filament yarn bobbins on current winding machines. Specifically, the cradle pressure control system on current winding machines is mostly based on open-loop control of the mechanical structure. The control accuracy and consistency are difficult to guarantee. When the cradle pressure control target value needs to be changed, the angle and tightness of the spring mechanism must be manually adjusted. This process must be done manually on a spindle-by-spindle basis, and the operation requires the assistance of other tools such as wrenches and spring scales. This requires a lot of manpower, is difficult to operate, and has poor stability and consistency. Utility Model Content

[0029] Figure 1 This is a structural diagram of a winding machine cradle control system 100 provided in an embodiment of the present application. Figure 2 This is a front view of a winding machine cradle control system 100 provided in an embodiment of the present application. Figure 3 This is a side view of the winding machine cradle control system 100 provided in an embodiment of the present application. Figures 1 to 3 As shown, an embodiment of the present application provides a winding machine cradle control system 100, which includes a cradle lifting mechanism 10, an angle sensor 20, a weight sensor 30, and a control unit (not shown in the figure).
[0030] The cradle lifting mechanism 10 is used to drive the cradle 1 to rise or fall, so as to change the pressure of the yarn bobbin on the cradle 1 on the roller 3 or the groove drum.
[0031] As an example, the cradle lifting mechanism 10 is disposed below either side of the cradle 1. The cradle lifting mechanism 10 includes a motor bracket 11, a motor, a ball screw 13, a screw nut 14, and a fixed bracket 15. The motor bracket 11 is connected to the cradle 1, the motor is mounted on the motor bracket 11, the motor output end is connected to the ball screw 13, the screw nut 14 is mounted on the ball screw 13, and the fixed bracket 15 is fixed in position and connected to the screw nut 14. The motor is preferably a stepper motor 12, which features high precision, high torque, fast response, high reliability, and good control performance.
[0032] When the stepper motor 12 is working, the stepper motor 12 drives the ball screw 13 to rotate, so that the ball screw 13 rises or falls relative to the fixed screw nut 14, and then the ball screw 13 drives the stepper motor 12 and the motor bracket 11 to rise or fall, thereby lifting or pulling down the cradle 1, thereby adjusting the pressure of the yarn bobbin on the cradle 1 on the roller 3 or the grooved drum.
[0033] The angle sensor 20 is used to detect the rotation angle of the cradle 1. In one example, the angle sensor 20 is mounted near the end of the cradle 1's rotating shaft, which is rotatably connected to the cradle base 2. In another example, the angle sensor 20 is mounted on the cradle 1's rotating shaft, which is rotatably connected to the cradle base 2. When the cradle 1 rotates, the angle sensor 20 detects the rotation angle of the rotating shaft, which is equivalent to detecting the rotation angle of the cradle 1.
[0034] It will be understood by those skilled in the art that the type and installation method of the angle sensor 20 can be set according to actual conditions. In addition to the larger angle sensor 20 that is set next to the rotating shaft as shown in the figure, there is also a smaller angle sensor that can be directly installed on the rotating shaft.
[0035] The weight sensor 30 detects the pressure exerted by the bobbin on the cradle 1 on the roller 3 or the grooved drum. For example, the sensing end of the weight sensor 30 faces upward and contacts a pressure plate 40, which is connected to the support 4 of the central axis of the roller 3. When the bobbin on the cradle 1 contacts the roller 3, the pressure exerted by the bobbin on the roller 3 is transmitted through the central axis of the roller 3, the support 4, and the pressure plate 40 to the sensing end of the weight sensor 30, which then detects this pressure.
[0036] Those skilled in the art will appreciate that, for the grooved drum, a structure similar to that in the above example may also be used to transmit the pressure of the yarn bobbin pressing on the grooved drum to the detection end of the weight sensor 30, which will not be elaborated here.
[0037] It should be noted that the pressure exerted by the bobbin on the roller 3 or the grooved drum is primarily static or slowly changing. Compared to a pressure sensor that can quickly respond to dynamic pressure changes, the weight sensor 30 can more accurately measure this static or slowly changing load. Of course, in theory, a pressure sensor can be used instead of the weight sensor 30 to detect the pressure exerted by the bobbin on the roller 3 or the grooved drum. However, the specific considerations need to be comprehensive, based on factors such as the actual application scenario, accuracy requirements, dynamic response requirements, and cost.
[0038] The control unit is in communication with the cradle lifting mechanism 10 , the angle sensor 20 and the weight sensor 30 . The control unit is used to control the cradle lifting mechanism 10 to operate according to signals from the angle sensor 20 and the weight sensor 30 .
[0039] As an example, the control unit includes a control circuit board and a touch screen. The control circuit board is electrically connected to the touch screen and is in communication with the stepper motor 12, angle sensor 20, and weight sensor 30 of the cradle lifting mechanism 10. The touch screen allows the user to set the pressure of the yarn bobbin on the roller or grooved drum and the diameter of the yarn bobbin.
[0040] Those skilled in the art will appreciate that, in addition to being specifically provided for the winding machine cradle control system 100 , the control unit may also be implemented through the control system of the winding machine.
[0041] The present application also provides a winding machine, which includes the above-mentioned winding machine cradle control system 100.
[0042] The operating process of the winding machine cradle control system 100 is as follows: First, the pressure values of the yarn bobbins on the rollers or grooved drums, from empty to full, as well as the empty and full bobbin diameters, are set on the control unit's touchscreen. Then, the winding machine begins operation. Throughout the winding process, the angle sensor 20 detects the rotation angle of the cradle 1 in real time and transmits the detected angle value to the control circuit board of the control unit. The weight sensor 30 detects the pressure of the yarn bobbins on the cradle 1 on the rollers 3 or grooved drums in real time and transmits the detected pressure value to the control circuit board of the control unit. Based on the set pressure value, the control circuit board controls the stepper motor 12 of the cradle lifting mechanism 10 to drive the cradle 1 up or down, changing the pressure applied by the yarn bobbins (and the yarn wound thereon) on the rollers 3 or grooved drums to achieve the set pressure value.
[0043] In summary, the embodiments of the present application provide a winding machine cradle control system and a winding machine. The winding machine cradle control system includes a cradle lifting mechanism, an angle sensor, a weight sensor, and a control unit. The control unit controls the cradle lifting mechanism to drive the cradle up or down, and adjusts the pressure of the yarn bobbin on the cradle on the roller or groove drum based on the rotation angle of the cradle detected by the angle sensor and the pressure of the yarn bobbin on the cradle on the roller or groove drum detected by the weight sensor. The winding machine cradle control system and the winding machine can achieve full-process automated control of the pressure of the yarn bobbin on the roller or groove drum from empty to full bobbin, are easy to operate, and can ensure control accuracy and consistency, achieving perfect control of the yarn bobbin shape and density. It is particularly suitable for winding high-elastic filament yarn.
[0044] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited to this. Any technician familiar with the field can easily think of various changes or replacements within the technical scope disclosed in this application, such as the installation position, type, and support method of the stepper motor and sensor, which should all be included in the scope of protection of the present application.
