Description

Technical Field

[0001] The invention belongs to the technical field of spinning equipment, and particularly relates to a cutting device and a cutting method for paper tube tail yarns 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. The existing winding machine switching technology usually follows the following steps: After 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, and then controlling 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 starts to move immediately. 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] In the initial action 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 needle cylinder solenoid valve, driving the tail wire 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 and is ready for the next 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 piece on it accurately pushes the wire bundle into the tail wire groove of the chuck B paper tube 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 in further, 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 sequence and switching steps are as follows: Figure 3 、 Figure 4 As shown;

[0005] However, with the increasing demand for high-strength yarns, especially those with a density of 6000D and above, existing switching technologies have exposed many shortcomings. First, during the high-strength yarn switching process, the yarn bundle is easily broken by the two chucks, resulting in a scattered tail. This can not only entangle equipment such as the spinning position bracket, causing the yarn cake to slip, equipment damage, and product quality degradation, but can also affect the operating efficiency of the automatic winder. Secondly, the thicker the twisted yarn, the greater the lateral force exerted on the chuck when the yarn bundle breaks, which can disrupt the dynamic balance of the chuck shaft, causing the inverter to alarm for overcurrent, and reducing equipment production efficiency. In addition, in the existing technology, the adjustment of the number of tail yarn turns in the paper tube tail yarn slot depends on the air intake speed of the wire guide plate cylinder or the adjustment of the LS16-1 installation position. This method is not only difficult to adjust online in real time, but also the difficulty of adjustment increases significantly as the yarn bundle becomes thicker, 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 paper tube tail of a winding machine (referred to as 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, and 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 needle cylinder is provided with a tail wire needle cylinder solenoid valve;

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

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

[0014] The invention 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, which 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, which activates the wire moving hook cylinder and drives the wire moving hook forward to hook the wire bundle and enter the wire guide groove, freeing the wire bundle 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 needle cylinder solenoid valve, so that the tail wire needle cylinder moves and drives the tail wire 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 resets and the yarn bundle enters the wire guide groove.

[0020] After the control panel receives the signal from LS16-1, it controls the PLC to send a start signal with a duration of 1 second to the solenoid valve of the shear cylinder, so that the shear cylinder moves and drives the shears to cut the tow. After the shears cut the tow, the tail wire begins to be wound in the tail wire groove of the paper tube. On the other hand, it controls the PLC to send a stop signal to the solenoid valve of the tail wire needle cylinder after a delay time t, so that the tail wire 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 winding is switched;

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

[0023] After receiving the signal from 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 cutting device A of the present invention over the cutting 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 escapes from the tail wire air needle. In the present invention, LS16-1 is installed at the position where the tow just fits into 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, avoiding a series of problems caused by breaking, and making it possible to adjust the number of tail wire coils in the paper tube tail wire groove online.

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

[0031] The winding machine chuck A is full of silk cakes. At this time, 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, it triggers LS30, which 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, which activates the wire moving hook cylinder and drives the wire moving hook forward to hook the wire bundle and enter the wire guide groove, freeing the wire bundle 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;

[0035] 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;

[0036] 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 controls the PLC to send a start signal to the solenoid valve of the tail wire needle cylinder, so that the tail wire needle cylinder moves and drives the tail wire needle to pop out. On the other hand, after a delay of 0.1 seconds, it sends a stop signal to the solenoid valve of the wire moving hook cylinder, so that the wire moving hook resets 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 groove of the paper tube begins to wind the tail wire. 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 winding is switched;

[0039] t <t b , t b The time interval between the time when LS16-1 is triggered and the time when LS16-2 is triggered 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 cutting method of the paper tube tail of the winding machine in the prior art is as follows Figure 4 As shown, the specific process is as follows:

[0042] The winding machine chuck A is full of silk cakes. At this time, 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, it triggers LS30, which 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, which activates the wire moving hook cylinder and drives the wire moving hook forward to hook the wire bundle and enter the wire guide groove, freeing the wire bundle 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 solenoid valve of the tail wire needle cylinder, so that the tail wire needle cylinder moves and drives the tail wire needle to pop out. On the other hand, it sends a stop signal to the solenoid valve of the wire moving hook cylinder after a delay of 0.1 seconds, so that the wire moving hook resets 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;

[0049] 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.

[0050] The improvement of the slitting method A of the present invention over the prior art slitting method of the paper tube tail of the winding machine 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 is actuated and the tail thread air needle is driven 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 is actuated and the tail thread air needle is driven 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 scissor cylinder solenoid valve, so that the scissor 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 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 coils in the paper tube tail wire groove online.

[0054] A wire cutting device for the paper tube tail of a winding machine (referred to as wire cutting device B), 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, and LS16-2;

[0060] The control panel is also connected to the PLC, which is also connected to the tail thread needle cylinder solenoid valve and the scissor cylinder solenoid valve;

[0061] The functions of the control panel are as follows:

[0063] 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;

[0064] 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 needle cylinder solenoid valve, so that the tail wire needle cylinder moves and drives the tail wire 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 resets and the yarn bundle enters the wire guide groove.

[0065] After receiving the signal from 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, causing the scissor cylinder to operate and drive the scissors to cut the tow. After the scissors cut the tow, the tail wire begins to be wound in the paper tube tail wire groove. On the other hand, the PLC controls the delay time t* and then sends a stop signal to the tail wire needle cylinder solenoid valve, causing the tail wire needle to retract. Among them, t* is the data obtained through pre-testing to ensure that the tow is wound in the paper tube tail wire groove.

[0066] After receiving the signal from 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.

[0067] The difference between the shredding device B of the present invention and the shredding device A is only that the control board controls the PLC delay time after receiving the signal sent by LS16-1.

[0068] A method for cutting the paper tube tail of a winding machine (referred to as cutting method B) using the above-mentioned cutting device for cutting the paper tube tail of a winding machine is described as follows:

[0069] The winding machine chuck A is full of silk cakes. At this time, the winding machine turntable rotates clockwise to make chuck A leave the winding position and chuck B enter the winding position;

[0070] When chuck B enters the winding position, it triggers LS30, which sends a signal to the control board;

[0094] Example 1

[0096] LS30 is the wire moving hook push position sensor, LS1 is the wire moving hook in-position position sensor, LS17 is the wire guide plate 1 initial position sensor, LS16-1 is the wire guide plate 1 adjustment position sensor (installed in the position where the wire bundle is just stuck in the tail wire groove 3 of the paper tube), and LS16-2 is the wire guide plate 1 end position sensor;

[0097] The wire hook cylinder is provided with a wire hook cylinder solenoid valve, the wire guide plate cylinder 2 is provided with a wire guide plate cylinder solenoid valve, and the tail wire needle cylinder is provided with a tail wire needle cylinder solenoid valve. Figure 7 、 Figure 8 As shown, the scissors 6 are driven by a scissor cylinder 7, and the scissor cylinder 7 is provided with a scissor cylinder solenoid valve 8;

[0098] The control panel is simultaneously connected to LS30, the wire moving hook cylinder solenoid valve, LS1, the wire guide plate cylinder solenoid valve, LS17, LS16-1, LS16-2, and the PLC. The PLC is also connected to the tail wire needle cylinder solenoid valve and the scissor cylinder solenoid valve 8.

[0099] The functions of the control panel are as follows:

[0100] After receiving the signal from LS30, the control board sends a start signal to the solenoid valve of the wire moving hook cylinder, which activates the wire moving hook cylinder and drives the wire moving hook forward to hook the wire bundle and enter the wire guide groove, freeing the wire bundle from the control of the shift fork.

[0101] After receiving the signal from LS1, the control board sends a start signal to the wire guide plate cylinder solenoid valve, which activates the wire guide plate cylinder 2 and drives the wire guide plate 1 to move the wire;

[0102] 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 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 resets and the yarn bundle enters the wire guide groove.

[0103] After receiving the signal from 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 8, so that the scissor cylinder 7 is actuated, driving the scissors 6 to cut the tow. After the scissors 6 cut the tow, the tail wire groove 3 of the paper tube begins to wind the tail wire. On the other hand, the control board controls the PLC to send a stop signal to the tail wire needle cylinder solenoid valve after a delay time t, so that the tail wire needle 4 is retracted.

[0104] 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 winding is switched;

[0105] t <t b , t b The time interval between the time when LS16-1 is triggered and the time when LS16-2 is triggered is obtained through a preliminary experiment;

[0106] 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 1.

[0107] A method for cutting the tail wire of a winding machine paper tube, using the above-mentioned cutting device for cutting the tail wire of a winding machine paper tube, such as Figures 9 to 13 As shown, the specific process is as follows:

[0108] The winding machine chuck A 9 is fully wound with silk cake. At this time, the winding machine turntable rotates clockwise to make chuck A 9 leave the winding position and chuck B 10 enter the winding position;

[0109] When chuck B 10 enters the winding position, it triggers LS30, which sends a signal to the control board;

[0110] After receiving the signal from LS30, the control board sends a start signal to the solenoid valve of the wire moving hook cylinder, which activates the wire moving hook cylinder and drives the wire moving hook forward to hook the wire bundle and enter the wire guide groove, freeing the wire bundle from the control of the shift fork.

[0111] 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;

[0112] After receiving the signal from LS1, the control board sends a start signal to the wire guide plate cylinder solenoid valve, which activates the wire guide plate cylinder 2 and drives the wire guide plate 1 to move the wire;

[0113] When the wire guide plate 1 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 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 resets and the wire bundle enters the wire guide groove.

[0126] After receiving the signal from LS1, the control board sends a start signal to the wire guide plate cylinder solenoid valve, which activates the wire guide plate cylinder 2 and drives the wire guide plate 1 to move the wire;

[0136] When the wire guide plate 1 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 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 resets and the wire bundle enters the wire guide groove.

[0137] When the wire guide plate 1 continues to move the wire, LS16-1 is triggered, and LS16-1 sends a signal to the control board. After receiving the signal from 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 8, so that the scissor cylinder 7 is actuated, driving the scissors 6 to cut the wire bundle. After the scissors 6 cut the wire bundle, the tail wire begins to be wound in the tail wire groove 3 of the paper tube. On the other hand, the PLC controls the delay time t* and then sends a stop signal to the tail wire air needle cylinder solenoid valve, so that the tail wire air needle 4 is retracted. Among them, t* is the data obtained through pre-testing to ensure that the wire bundle is wound in the tail wire groove 3 of the paper tube.

[0138] When the wire guide plate 1 continues to move the wire, LS16-2 is triggered, and LS16-2 sends a signal to the control board.
