Description

Technical Field

[0001] The invention belongs to the technical field of spinning equipment, and in particular relates to a cutting device and a cutting method for paper tube tail wires of a winding machine. Background Art

[0002] In the textile industry, the winding machine is a key device for achieving efficient winding of yarn bundles. The stability and efficiency of its switching technology directly affect the continuity of the production process and product quality. Existing winding machine switching technology usually follows the following steps: When the winding machine chuck A completes the winding, the turntable rotates clockwise to make the chuck B enter the winding position, triggering the LS30 signal, which in turn controls the movement of the wire moving hook cylinder to hook the yarn bundle into the wire guide groove. After the wire moving hook moves into place, the LS1 signal is triggered, and the wire guide plate cylinder immediately starts to move. Figure 1 As shown, there are three position sensors on the wire guide plate cylinder, namely LS16-1, LS16-2, and LS17, and its action process is divided into multiple fine steps.

[0003] At the initial stage of the wire guide plate, the control board detects that the LS17 signal changes from high level to low level, and immediately sends a signal to the tail wire air needle cylinder solenoid valve to drive the tail wire air needle to pop out to fix the wire bundle. At the same time, the control board disconnects the wire moving hook solenoid valve signal after a delay of 0.1 seconds, so that the wire moving hook is retracted, and the wire bundle smoothly enters the wire guide groove, ready for the next step of operation. Figure 5 As shown, the positions of the wire guide groove and tail wire air needle are as follows Figure 2 shown.

[0004] Afterwards, the wire guide plate continues to move, and the wire guide sheet on it accurately pushes the wire bundle into the tail wire groove of the paper tube of chuck B through the wire guide groove, and uses the tension generated by the rotation of the chuck to break the wire bundle. As the wire guide plate cuts further inward, the LS16-1 signal is triggered, and the control board disconnects the tail wire air needle cylinder solenoid valve signal, causing the tail wire air needle to retract, and the shift fork then shifts the wire bundle to start normal winding. Finally, the wire guide plate moves to the stroke terminal, triggering the LS16-2 signal. The control board confirms that the entire switching process is completed, and then sends a stop signal to the wire guide plate cylinder solenoid valve to reset the wire guide plate. The winding machine switching timing and switching steps are as follows: Figure 3 , Figure 4 As shown;

[0005] However, with the increasing production demand for high-strength yarns, especially those above 6000D, the existing switching technology has exposed many shortcomings. First, during the high-strength yarn switching process, the yarn bundle is easily broken by the two chucks, resulting in scattered tail yarn heads, which may not only entangle the spinning position bracket and other equipment, causing problems such as yarn cake slipping, equipment damage and product quality degradation, but also affect the operating efficiency of the automatic winder. Secondly, the thicker the stranded yarn, the greater the lateral force exerted on the chuck when the yarn bundle is broken, which may destroy the dynamic balance of the chuck shaft, cause the inverter to alarm overcurrent, and reduce the production efficiency of the equipment. In addition, in the prior art, the adjustment of the number of tail yarn turns in the tail yarn groove of the paper tube depends on the air intake speed of the wire guide plate cylinder or the adjustment of the installation position of LS16-1. This method is not only difficult to adjust online in real time, but also as the yarn bundle becomes thicker, the difficulty of adjustment increases significantly, further affecting the stability and flexibility of the switching process.

[0006] Therefore, in view of the above-mentioned problems existing in the existing winding machine switching technology, it is particularly important to develop an efficient, stable and easy-to-adjust wire cutting method. Summary of the invention

[0007] The purpose of the present invention is to solve the problems in the prior art and to provide a cutting device and a cutting method for the tail wire of a paper tube of a winding machine.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0009] A wire cutting device for the tail wire of a paper tube of a winding machine (referred to as a wire cutting device A), comprising a control panel, a wire moving hook, a wire moving hook cylinder, a wire guide plate, a wire guide plate cylinder, a tail wire air needle, a tail wire air needle cylinder, LS30, LS1, LS17, LS16-1, LS16-2;

[0010] LS30 is the wire moving hook push-out position sensor, LS1 is the wire moving hook in-position position sensor, LS17 is the wire guide plate initial position sensor, LS16-1 is the wire guide plate adjustment position sensor, and LS16-2 is the wire guide plate end position sensor;

[0011] The wire moving hook cylinder is provided with a wire moving hook cylinder solenoid valve, the wire guide plate cylinder is provided with a wire guide plate cylinder solenoid valve, and the tail wire air needle cylinder is provided with a tail wire air needle cylinder solenoid valve;

[0012] The control panel is connected to LS30, wire moving hook cylinder solenoid valve, LS1, wire guide plate cylinder solenoid valve, LS17, LS16-1, and LS16-2 at the same time;

[0013] LS16-1 is installed at the position where the tow is just stuck in the tail wire groove of the paper tube;

[0014] It also includes scissors, a scissor cylinder, and a PLC. The scissors are driven by the scissor cylinder, and the scissor cylinder is provided with a scissor cylinder solenoid valve;

[0015] The control panel is also connected to the PLC, and the PLC is also connected to the tail thread needle cylinder solenoid valve and the scissor cylinder solenoid valve;

[0016] The functions of the control panel are as follows:

[0017] After receiving the signal from LS30, the control board sends a start signal to the solenoid valve of the wire moving hook cylinder, so that the wire moving hook cylinder moves, drives the wire moving hook forward to hook the wire bundle and enter the wire guide groove, so that the wire bundle is free from the control of the shift fork;

[0018] After receiving the signal from LS1, the control board sends a start signal to the solenoid valve of the wire guide plate cylinder, so that the wire guide plate cylinder is activated and drives the wire guide plate to move the wire;

[0019] After the control board detects that LS17 changes from having a signal to having no signal, on the one hand, it controls the PLC to send a start signal to the tail wire air needle cylinder solenoid valve, so that the tail wire air needle cylinder moves and drives the tail wire air needle to pop out. On the other hand, after a delay of 0.1 seconds, it sends a stop signal to the wire moving hook cylinder solenoid valve, so that the wire moving hook is reset and the wire bundle enters the wire guide groove;

[0020] After the control panel receives the signal sent by LS16-1, on the one hand, it controls the PLC to send a start signal with a duration of 1 second to the scissor cylinder solenoid valve, so that the scissor cylinder moves and drives the scissors to cut the silk bundle. After the scissors cut the silk bundle, the tail silk begins to be wound in the tail silk groove of the paper tube. On the other hand, it controls the PLC to send a stop signal to the tail silk air needle cylinder solenoid valve after a delay time t, so that the tail silk air needle is retracted;

[0021] t=N×D×π / V, where N is the number of turns the tow needs to be wound in the tail groove of the paper tube, D is the diameter of the paper tube, and V is the linear speed of the tow when the winding is switched;

[0022] t <t b , t b is the time interval between the time when LS16-1 is triggered and the time when LS16-2 is triggered, and its value is obtained through a preliminary experiment;

[0023] After receiving the signal sent by LS16-2, the control board confirms that the entire winding switching process is completed, and then sends a stop signal to the wire guide plate cylinder solenoid valve to reset the wire guide plate.

[0024] The improvement of the slitting device A of the present invention over the slitting device of the paper tube tail of the winding machine in the prior art is that:

[0025] ① The installation position of LS16-1 is adjusted. In the prior art, LS16-1 is installed at the position where the tow just gets rid of the tail wire air needle. In the present invention, LS16-1 is installed at the position where the tow just gets stuck in the tail wire groove of the paper tube;

[0026] ②Added scissors, scissor cylinders and PLC;

[0027] ③The control panel is connected to the PLC, and the PLC is also connected to the tail thread needle cylinder solenoid valve and the scissor cylinder solenoid valve;

[0028] ④Adjusted the function of the control panel.

[0029] Through the above four improvements, the switching mode of the wire cutting device is changed from breaking to shearing, which avoids a series of problems caused by breaking, and makes it possible to adjust the number of tail wire circles in the tail wire groove of the paper tube online.

[0030] A method for cutting the paper tube tail wire of a winding machine using the cutting device for cutting the paper tube tail wire of the winding machine as described above (referred to as cutting method A, the switching process is as follows Fig.13 The specific process is as follows:

[0031] The winding machine chuck A is fully wound, and the winding machine turntable rotates clockwise to make chuck A leave the winding position and chuck B enter the winding position;

[0032] When chuck B enters the winding position, LS30 is triggered, and LS30 sends a signal to the control board;

[0033] After receiving the signal from LS30, the control board sends a start signal to the solenoid valve of the wire moving hook cylinder, so that the wire moving hook cylinder moves, drives the wire moving hook forward to hook the wire bundle and enter the wire guide groove, so that the wire bundle is free from the control of the shift fork;

[0034] After the wire moving hook moves into place, LS1 on the wire moving hook cylinder is triggered, and LS1 sends a signal to the control board;

On the one hand, it controls the PLC to send a start signal to the tail wire air needle cylinder solenoid valve, so that the tail wire air needle cylinder moves and drives the tail wire air needle to pop out. On the other hand, after a delay of 0.1 seconds, it sends a stop signal to the wire moving hook cylinder solenoid valve, so that the wire moving hook is reset and the wire bundle enters the wire guide groove.

[0037] When the wire guide plate continues to move the wire, LS16-1 is triggered, and LS16-1 sends a signal to the control board. After receiving the signal sent by LS16-1, the control board controls the PLC to send a start signal with a duration of 1 second to the scissor cylinder solenoid valve, so that the scissor cylinder moves and drives the scissors to cut the wire bundle. After the scissors cut the wire bundle, the tail wire begins to be wound in the tail wire groove of the paper tube. On the other hand, the control board controls the PLC to send a stop signal to the tail wire air needle cylinder solenoid valve after a delay time t, so that the tail wire air needle is retracted;

[0038] t=N×D×π / V, where N is the number of turns the tow needs to be wound in the tail groove of the paper tube, D is the diameter of the paper tube, and V is the linear speed of the tow when the winding is switched;

[0039] t <t b , t b is the time interval between the time when LS16-1 is triggered and the time when LS16-2 is triggered, and its value is obtained through a preliminary experiment;

[0040] When the wire guide plate continues to move the wire, LS16-2 is triggered, and LS16-2 sends a signal to the control board. After receiving the signal sent by LS16-2, the control board confirms that the entire winding switching process is completed, and then sends a stop signal to the wire guide plate cylinder solenoid valve to reset the wire guide plate.

[0041] The prior art method for cutting the paper tube tail wire of the winding machine is as follows Figure 4 As shown, the specific process is as follows:

[0042] The winding machine chuck A is fully wound, and the winding machine turntable rotates clockwise to make chuck A leave the winding position and chuck B enter the winding position;

[0043] When chuck B enters the winding position, LS30 is triggered, and LS30 sends a signal to the control board;

[0044] After receiving the signal from LS30, the control board sends a start signal to the solenoid valve of the wire moving hook cylinder, so that the wire moving hook cylinder moves, drives the wire moving hook forward to hook the wire bundle and enter the wire guide groove, so that the wire bundle is free from the control of the shift fork;

[0045] After the wire moving hook moves into place, LS1 on the wire moving hook cylinder is triggered, and LS1 sends a signal to the control board;

[0046] After receiving the signal from LS1, the control board sends a start signal to the solenoid valve of the wire guide plate cylinder, so that the wire guide plate cylinder is activated and drives the wire guide plate to move the wire;

[0047] When the wire guide plate starts to move the wire, the control board detects that LS17 changes from having a signal to having no signal. On the one hand, it sends a start signal to the tail wire air needle cylinder solenoid valve, so that the tail wire air needle cylinder moves and drives the tail wire air needle to pop out. On the other hand, after a delay of 0.1 seconds, it sends a stop signal to the wire moving hook cylinder solenoid valve, so that the wire moving hook is reset and the wire bundle enters the wire guide groove.

[0048] When the wire guide plate continues to move the wire, LS16-1 is triggered, and LS16-1 sends a signal to the control board. After receiving the signal sent by LS16-1, the control board sends a stop signal to the tail wire air needle cylinder solenoid valve, so that the tail wire air needle is retracted;

After receiving the signal sent by LS16-2, the control board confirms that the entire winding switching process is completed, and then sends a stop signal to the wire guide plate cylinder solenoid valve to reset the wire guide plate.

[0050] The improvement of the slitting method A of the present invention over the slitting method of the paper tube tail of the winding machine in the prior art is that:

[0051] ① The present invention controls the PLC to send a start signal to the tail thread air needle cylinder solenoid valve after the control board detects that LS17 changes from having a signal to having no signal, so that the tail thread air needle cylinder moves and drives the tail thread air needle to pop out. The prior art controls the PLC to send a start signal to the tail thread air needle cylinder solenoid valve after the control board detects that LS17 changes from having a signal to having no signal, so that the tail thread air needle cylinder moves and drives the tail thread air needle to pop out;

[0052] ② After the control board of the present invention receives the signal sent by LS16-1, on the one hand, it controls the PLC to send a start signal with a duration of 1 second to the scissors cylinder solenoid valve, so that the scissors cylinder is actuated, driving the scissors to cut the silk bundle, and after the scissors cut the silk bundle, the tail silk begins to be wound in the tail silk groove of the paper tube; on the other hand, it controls the PLC to send a stop signal to the tail silk air needle cylinder solenoid valve after a delay time t, so that the tail silk air needle is retracted. In the prior art, after the control board receives the signal sent by LS16-1, it sends a stop signal to the tail silk air needle cylinder solenoid valve, so that the tail silk air needle is retracted.

[0053] Through the above two improvements, the wire cutting method is switched from breaking to shearing, avoiding a series of problems caused by breaking, and making it possible to adjust the number of tail wire circles in the paper tube tail wire groove online.

On the one hand, it controls the PLC to send a start signal to the tail wire air needle cylinder solenoid valve, so that the tail wire air needle cylinder moves and drives the tail wire air needle 4 to pop out. On the other hand, after a delay of 0.1 seconds, it sends a stop signal to the wire moving hook cylinder solenoid valve, so that the wire moving hook is reset and the wire bundle enters the wire guide groove.

On the other hand, the control board controls the PLC to send a stop signal to the tail wire air needle cylinder solenoid valve after a delay time t, so that the tail wire air needle 4 is retracted;

[0115] t=N×D×π / V, where N is the number of turns the tow needs to be wound in the tail groove 3 of the paper tube, D is the diameter of the paper tube, and V is the linear speed of the tow when the winding is switched;
