Description

Technical Field

[0001] This invention belongs to the field of textile equipment manufacturing technology and relates to the improvement of the control system of automatic winding machine, specifically a single-spindle intelligent start-stop control system and control method for a dual-variety automatic winding machine. Background Technology

[0002] With rising labor costs, more and more textile mills are adopting tray-type automatic winding machines. However, ordinary tray-type automatic winding machines can only produce one product at a time. In order to meet the needs of textile mills for multi-variety, small-batch production, the applicant has designed and developed a dual-variety tray-type automatic winding machine and applied for a Chinese invention patent, which has been granted (authorization announcement number: CN112938647B).

[0003] The spindle is the core device in an automatic winding machine responsible for winding bobbins into knotless bobbins, and it is also the main energy consumer in the automatic winding machine. Without spindle start-stop control, energy waste is too high, and frequent spindle movements easily cause wear and tear on mechanical parts, thus reducing their lifespan. Manual start-stop control of the spindle is also an option, but spinning mills operate 24 / 7, and nighttime work is too demanding for manual labor. If not handled promptly, the spindle may repeatedly start when there is no bobbin, increasing energy consumption; or it may fail to start when there is bobbin, reducing production efficiency. Adding a tray detection sensor to each spindle for one-to-one control (see invention patent CN112938647B) achieves control functionality, but the added equipment cost is high, and each spindle requires independent design and installation space.

[0004] Therefore, how to design an intelligent start-stop control system and method for a single spindle of a dual-product automatic winding machine to solve the problem of automatic start-stop control of a single spindle of a dual-product automatic winding machine, while realizing intelligent control of the control system, effectively controlling costs, reducing space occupation and reducing energy consumption, is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] To address the aforementioned problems and shortcomings of existing technologies, this invention provides an intelligent start-stop control system and method for a single spindle of a dual-product automatic winding machine. This system solves the problem of automatic start-stop control for a single spindle of a dual-product automatic winding machine, while simultaneously achieving intelligent control of the system, effectively controlling costs, reducing space occupation, and lowering energy consumption.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A dual-variety automatic winding machine single-spindle intelligent start-stop control system includes an automatic winding machine head, a yarn handling device, a yarn conveying channel, a tube inlet channel, several spindle sections, post-spindle section sensors, and an automatic winding machine controller. The spindle section closest to the yarn handling device is called the first spindle section, and the spindle section closest to the automatic winding machine head is called the last spindle section. The system is characterized in that the number of post-spindle section sensors is equal to half the number of spindle sections or half the number of spindle sections plus one. Starting from the first spindle section, one post-spindle section sensor is placed every two spindle sections. If there are fewer than two spindle sections remaining, the sensor is placed at the end of the last spindle section. The automatic winding machine controller is connected to each post-spindle section sensor. The automatic winding machine controller includes a single-spindle start-stop control logic module. The automatic winding machine controller receives signals from each post-spindle section sensor and starts or stops the operation of the automatic winding machine single spindle in the spindle section according to the single-spindle start-stop control logic set in the single-spindle start-stop control logic module.

[0008] Further improvements to the above technical solution include a host computer, a whole machine alarm device, and a single spindle alarm device. The host computer is connected to the automatic winding machine controller, and the automatic winding machine controller is connected to the whole machine alarm device.

[0009] Further improvements to the above technical solution: The dual-variety automatic winding machine adopts a left-hand carriage or a right-hand carriage. The yarn feeding channel on the left-hand carriage is arranged parallel to the yarn feeding channel on the right-hand carriage. The yarn feeding direction of the yarn feeding channel on the left-hand carriage is first from the yarn processing device to the head of the automatic winding machine, and then turns from the tube inlet channel to the yarn processing device, while feeding the yarn to the spindle during the feeding process. The yarn feeding direction of the yarn feeding channel on the right-hand carriage is from the yarn processing device to the head of the automatic winding machine, while feeding the yarn into the tube inlet channel and feeding it to the spindle during the feeding process.

[0010] This invention discloses a control method for the above-mentioned intelligent start-stop control system for a single spindle of a dual-product automatic winder. The method is characterized by firstly setting a single-spindle start-up logic in the start-stop control logic module. This single-spindle start-up logic includes basic single-spindle start-up control logic, direct single-spindle start-up control logic, and single-spindle counting start-up control logic. The basic single-spindle start-up control logic is as follows: when the automatic winder controller starts, it first detects the start-up status of the single spindle in the corresponding spindle section. If there are any unstarted single spindles in the section, the corresponding single spindle in that section is started. If all single spindles are started and running... If the spindle section sensor is located in front of the yarn feeding direction of the spindle section's inlet channel, no operation is performed. The single-spindle direct start control logic is as follows: if the sensor after the spindle section is located in front of the yarn feeding direction of the spindle section's inlet channel, the direct start control logic is adopted, that is, when the sensor after the spindle section receives a signal, the spindle section is directly started. The single-spindle counting start control logic is as follows: if the sensor after the spindle section is located behind the yarn feeding direction of the spindle section's inlet channel, the counting start control logic is adopted, that is, when the sensor after the spindle section receives a signal, counting begins, and when the count reaches the counting threshold, the spindle section is started. If all spindle sections are started, the count is reset to zero. The control method includes the following steps:

[0011] Step 1: According to the set basic control logic for single-spindle start-up, when the automatic winding machine controller controls the start-up of the spindle section, it first checks the start-up status of the single-spindle in the section. If there are any unstarted automatic winding machine spindles in the section, the corresponding automatic winding machine spindle in the section will be started. If all automatic winding machine spindles are started and running, no operation will be performed.

[0012] Step 2: When the automatic winding machine controller controls the operation of a single spindle in the starting section, if the sensor after the spindle section is located in front of the yarn conveying direction of the inlet tube channel of the spindle section, the automatic winding machine controller controls the operation of the single spindle according to the single spindle direct start control logic; if the sensor after the spindle section is located behind the yarn conveying direction of the inlet tube channel of the spindle section, the automatic winding machine controller controls the operation of the single spindle according to the single spindle counting start control logic.

[0013] Improvement to the above technical solution: In the single-spindle counting start control logic, the counting start threshold needs to be calculated based on the position of the sensor after the corresponding spindle section, the length of the spindle section, and the number of storage tubes after the single spindle. When the sensor after the corresponding spindle section is located at the head of the spindle section, the calculation formula for the counting start threshold is as shown in equation (1):

[0014]

[0015] In the formula, M1 is the counting start threshold where the sensor position after the spindle section is located at the head of the spindle section; N1 is the length of the spindle section; and N2 is the number of storage tubes after a single spindle.

[0016] Further improvements to the above technical solution: In the single-spindle counting start control logic, the post-spindle sensor can only provide detection of the yarn conveying direction of the tube inlet channel. When the post-spindle sensor is located at the junction of the two-product segmentation, the spindle section of the right-hand carriage located behind the yarn conveying direction of the tube inlet channel at the two-product segmentation point is directly started according to the post-spindle sensor; the spindle section of the left-hand carriage located behind the yarn conveying direction of the tube inlet channel at the two-product segmentation point is started by counting according to the post-spindle sensor of the next spindle section. In this case, the counting start threshold is as shown in equation (2):

[0017]

[0018] In the formula, M2 is the counting start threshold where the sensor position after the spindle section is located at the beginning of the next spindle section; Q is the total number of counts required to start all spindles in the next spindle section, and the calculation formula is shown in formula (3):

[0019] Q = N³ × (N² + 1) (3)

[0020] In the formula, N3 is the length of the next ingot section.

[0021] Further improvements to the above technical solution: Set a single-spindle bobbin-less yarn stop control logic in the start-stop control logic module; the single-spindle bobbin-less yarn stop control logic is as follows: when single-spindle bobbin-less yarn is provided, the operation will automatically stop and the status signal will be fed back to the automatic winding machine controller for use in the next start-up, and a single-spindle alarm will be triggered through the single-spindle alarm device.

[0022] Further improvements to the above technical solution: When executing the single-spindle bobbin-less yarn stop control logic, if the single spindle fails to attempt to use secondary bobbin c, the single-spindle stop control logic is executed to stop the single spindle, and at the same time, a single-spindle alarm is triggered through the single-spindle alarm device, where c is at least 3.

[0023] Further improvements to the above technical solution: An alarm logic for pipe inlet channel blockage is set in the start / stop control logic module. The pipe inlet channel blockage alarm logic uses the sensor signal after the spindle section to trigger an alarm on the entire machine's alarm device and displays the alarm details on the host computer when a blockage occurs in the pipe inlet channel.

[0024] Further improvements to the above technical solution: If the duration of the sensor signal after any spindle section exceeds t1 seconds after startup, or if the sensor has no signal after any spindle section for more than t2 seconds after startup, it is considered that the inlet pipe channel after the spindle section is blocked, and an alarm is triggered by the whole machine alarm device and the alarm details are displayed by the host computer.

[0025] The advantages and positive effects of this invention are:

[0026] 1. This invention realizes intelligent start-stop control of a single spindle in a dual-product automatic winding machine, reducing the risk of affecting production efficiency;

[0027] 2. Compared with manual control: The novel intelligent start-stop control system for single spindles of the dual-product automatic winding machine proposed in this invention can realize the automatic start and stop of a single spindle, which greatly reduces labor costs and pressure;

[0028] 3. Compared with the addition of a tray detection sensor for each spindle: The number of sensors required by the dual-variety automatic winding machine single-spindle intelligent start-stop control system of the present invention is significantly reduced compared with the one-to-one control method of adding a tray detection sensor for each spindle. It can complete the single-spindle intelligent start-stop control function, while effectively controlling costs, reducing space and energy consumption, and promoting the intelligent and green upgrading of the textile industry.

[0029] 4. Regarding configuration flexibility: The novel dual-product automatic winding machine single-spindle intelligent start-stop control system proposed in this invention is designed with a dual-product single-spindle intelligent start-stop control logic table, which is flexible in configuration and can be adapted to dual-product automatic winding machines of any spindle length and left or right hands.

Detailed Implementation

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0035] See Figures 1-3This invention discloses an embodiment of a dual-variety automatic winding machine single-spindle intelligent start-stop control system, comprising an automatic winding machine head 19, a yarn handling device 10, yarn conveying channels (including a variety A conveying channel 17 and a variety B conveying channel 18), several spindle sections (including spindle section 1, spindle section 2, spindle section 3, spindle section 4, spindle section 5, spindle section 6, spindle section 7, spindle section 8, and spindle section 9), post-spindle section sensors, and an automatic winding machine controller. Preferably, each spindle section contains 6 or 8 single spindles, and 2 or 3 yarns can be stored after each spindle; the yarn handling device 10 is a CBF (Cycloth-Cured Fiber). The spindle section closest to the yarn handling device 10 (spindle section 1) is called the first spindle section, and the spindle section closest to the automatic winding machine head 19 (spindle section 9) is called the last spindle section. The number of post-spindle sensors is equal to half the number of spindles or half the number of spindles plus 1. In this embodiment, there are a total of 9 spindles (an odd number). Therefore, the number of post-spindle sensors is (9+1) / 2 = 5, including post-spindle sensor A11, post-spindle sensor B12, post-spindle sensor C13, post-spindle sensor D14, and post-spindle sensor E15. Starting from the first spindle (spindle 1), one post-spindle sensor is placed every two spindles, in the following order: post-spindle sensor A11, post-spindle sensor B12, post-spindle sensor C13, and post-spindle sensor D14. There are fewer than two remaining spindles, i.e., only the last spindle (spindle 9). Therefore, post-spindle sensor E15 is placed at the end of the last spindle. The automatic winding machine controller is connected to the post-spindle sensors (post-spindle sensor A11, post-spindle sensor B12, post-spindle sensor C13, post-spindle sensor D14, and post-spindle sensor E15). The automatic winding machine controller includes a single-spindle start / stop control logic module. The automatic winding machine controller receives signals from each post-spindle sensor (including post-spindle sensor A11, post-spindle sensor B12, post-spindle sensor C13, post-spindle sensor D14, and post-spindle sensor E15) and starts or stops the operation of the automatic winding machine single spindle in the spindle section according to the single-spindle start / stop control logic set in the single-spindle start / stop control logic module.

[0036] Furthermore, it also includes a host computer, a whole machine alarm device, and a single spindle alarm device. The host computer is connected to the automatic winding machine controller, and the automatic winding machine controller is connected to the whole machine alarm device.

[0037] Furthermore, the dual-variety automatic winding machine employs either a left-hand carriage or a right-hand carriage. The yarn conveying channels on the left-hand carriage (including variety A conveying channel 17 and variety B conveying channel 18) are arranged parallel to those on the right-hand carriage. The yarn conveying direction of the yarn conveying channel on the left-hand carriage is first from the yarn handling device 10 to the automatic winding machine head 19, and then turns from the inlet channel 16 to the location of the yarn handling device 10, conveying the yarn to the spindle during the conveying process. The yarn conveying direction of the yarn conveying channel on the right-hand carriage is from the yarn handling device 10 to the location of the automatic winding machine head 19, and during the conveying process, the yarn is fed into the inlet channel 16 and conveyed to the spindle.

[0038] like Figure 3 As shown, the control principle of this invention is as follows:

[0039] 1. The automatic winding machine controller is connected to the spindle section sensor, the whole machine alarm device and the host computer; the automatic winding machine individual spindle is connected to the host computer, and the individual spindle is equipped with an individual spindle alarm device.

[0040] 2. After the spindle section, the sensor directly sends sensor signals to the automatic winding machine controller.

[0041] 3. When the automatic winding machine controller sends a single spindle start signal, the single spindle of the automatic winding machine is indirectly started through the host computer.

[0042] 4. If there is no yarn tube, the single spindle will stop, and the single spindle alarm device will sound.

[0043] 5. The start / stop status of a single spindle is indirectly fed back to the automatic winding machine controller via the host computer.

[0044] 6. When the channel is blocked, the automatic winding machine controller sends an alarm to the whole machine alarm device and at the same time sends an alarm detail to the host computer.

[0045] See Figures 1-3An embodiment of the control method for the above-mentioned intelligent start-stop control system for a single spindle of a dual-product automatic winder according to the present invention firstly sets up a single spindle start-up logic in the single spindle start-stop control logic module. The single spindle start-up logic includes a basic single spindle start-up control logic, a direct single spindle start-up control logic, and a single spindle counting start-up control logic. The basic single spindle start-up control logic is as follows: when the automatic winder controller starts, it first detects the start-up status of the single spindle of the automatic winder in that spindle section. If there is a single spindle of the automatic winder in the spindle section that has not started, then the corresponding single spindle of the automatic winder in that spindle section is started. If all single spindles of the automatic winder are started... If the condition is met, no operation is performed. The single-spindle direct start control logic is as follows: if the sensor after the spindle section is located in front of the yarn feeding direction of the spindle section's inlet channel, the direct start control logic is adopted, that is, when the sensor after the spindle section receives a signal, the spindle section is directly started. The single-spindle counting start control logic is as follows: if the sensor after the spindle section is located behind the yarn feeding direction of the spindle section's inlet channel, the counting start control logic is adopted, that is, when the sensor after the spindle section receives a signal, counting begins, and when the count reaches the counting threshold, the spindle section is started. If all spindle sections are started, the count is reset to zero. The control method includes the following steps:

[0046] Step 1: According to the set basic control logic for single-spindle start-up, when the automatic winding machine controller controls the start-up of the spindle section, it first checks the start-up status of the single-spindle in the section. If there are any unstarted automatic winding machine spindles in the section, the corresponding automatic winding machine spindle in the section will be started. If all automatic winding machine spindles are started and running, no operation will be performed.

[0047] Step 2: When the automatic winding machine controller controls the operation of a single spindle in the starting spindle section, if the sensor after the spindle section is located in front of the yarn conveying direction of the inlet tube channel of the spindle section, the automatic winding machine controller controls the operation status of the single spindle according to the single spindle direct start control logic; if the sensor after the spindle section is located in front of the yarn conveying direction of the inlet tube channel of the spindle section, the automatic winding machine controller controls the operation status of the single spindle according to the single spindle counting start control logic.

[0048] Furthermore, in the single-spindle counting start control logic, the counting start threshold needs to be calculated based on the position of the sensor after the corresponding spindle section, the length of the spindle section, and the number of storage tubes after the single spindle. When the sensor after the corresponding spindle section is located at the beginning of the spindle section, the calculation formula for the counting start threshold is as shown in equation (1):

[0049]

[0050] In the formula, M1 is the counting start threshold where the sensor position after the spindle section is located at the head of the spindle section; N1 is the length of the spindle section, which is 6 or 8; N2 is the number of storage tubes after a single spindle, which is 2 or 3.

[0051] Furthermore, in the single-spindle counting start control logic, the spindle section post-sensor S can only provide detection of the yarn conveying direction of the tube inlet channel. When the spindle section post-sensor is located at the junction of the two-product segmentation, the spindle section of the right-hand carriage located behind the yarn conveying direction of the tube inlet channel at the two-product segmentation point is directly started according to the spindle section post-sensor; the spindle section of the left-hand carriage located behind the yarn conveying direction of the tube inlet channel at the two-product segmentation point is started by counting according to the spindle section post-sensor of the next spindle section. In this case, the counting start threshold is as shown in equation (2):

[0052]

[0053] In the formula, M2 is the counting start threshold where the sensor position after the spindle section is located at the beginning of the next spindle section; Q is the total number of counts required to start all spindles in the next spindle section, and the calculation formula is shown in formula (3):

[0054] Q = N³ × (N² + 1) (3)

[0055] In the formula, N3 is the length of the next spindle section, which is 6 or 8.

[0056] In this embodiment of the invention, a dual-product single-spindle intelligent start-stop control logic table was designed according to the rules, as shown in Table 1.

[0057] Table 1 Calculation of Count Threshold

[0058] Located at the head of the ingot section 6 2 none M1＝9 Located at the head of the ingot section 6 3 none M1＝12 Located at the head of the ingot section 8 2 none M1＝12 Located at the head of the ingot section 8 3 none M1＝16 Located at the head of the rear ingot section 6 2 6 M2＝27 Located at the head of the last ingot section 6 3 6 M2＝36 Located at the head of the rear ingot section 6 2 8 M2＝33 Located at the head of the rear ingot section 6 3 8 M2＝44 Located at the head of the rear ingot section 8 2 6 M2＝30 Located at the head of the last ingot section 8 3 6 M2＝42 Located at the head of the rear ingot section 8 2 8 M2＝36 Located at the head of the last ingot section 8 3 8 M2＝48

[0059] As shown in Table 1, the vertical header of the table represents whether the sensor after the spindle counting start-up of a certain spindle section is located at the beginning of the spindle section or at the beginning of the next spindle section in the yarn conveying direction of the tube inlet channel of the spindle section; the horizontal header of the table represents the parameters of the above formula and the final calculated counting start-up threshold.

[0060] Furthermore, a single-spindle bobbin-less yarn stop control logic is set in the start / stop control logic module; the single-spindle bobbin-less yarn stop control logic is as follows: when single-spindle bobbin-less yarn is provided, the operation will automatically stop and the status signal will be fed back to the automatic winding machine controller for use in the next start-up, and a single-spindle alarm will be triggered through the single-spindle alarm device.

[0061] Specifically: When executing the single-spindle no-tube yarn stop control logic, if the single spindle fails to attempt to use the secondary tube c, the single-spindle stop control logic is executed to stop the single spindle, and at the same time, a single-spindle alarm is triggered through the single-spindle alarm device, where c is at least 3.

[0062] Furthermore, a pipe inlet channel blockage alarm logic is set in the start / stop control logic module. The pipe inlet channel blockage alarm logic uses the sensor signal after the spindle section to trigger an alarm through the whole machine alarm device and display the alarm details on the host computer when a blockage occurs in the pipe inlet channel.

[0063] Specifically: if the duration of the sensor signal after any spindle section exceeds t1 seconds after startup, or if the sensor has no signal after any spindle section for more than t2 seconds after startup, it is considered that the inlet pipe channel after the spindle section is blocked, and an alarm is triggered by the whole machine alarm device and the alarm details are displayed by the host computer.

[0064] Preferably, the value range of t1 is 40-80 seconds, and the value range of t2 is 90-180 seconds.

[0065] When implementing this invention, the single-spindle start-up logic of the left-hand and right-hand carriages of the dual-variety automatic winding machine is constructed according to the rules, as shown in Tables 2 and 3.

[0066] Table 2. Start-up Logic of Single Spindle on Right Hand Cart of Dual-Product Automatic Winding Machine

[0067]

[0068] Table 3. Start-up Logic of Single Spindle on Left Handcart of Dual-Product Automatic Winding Machine

[0069]

[0070]

[0071] Note: In Tables 2 and 3, A, B, C, D, and E represent post-spindle section sensor A, post-spindle section sensor B, post-spindle section sensor C, post-spindle section sensor D, and post-spindle section sensor E, respectively.

[0072] As shown in Table 2-3, the vertical header of the table represents "the division of two varieties between two spindle sections", that is, the section before the division point is variety A and the section after the division point is variety B; the horizontal header of the table represents "single spindle start-up of a certain spindle section", that is, a single spindle in a certain spindle section can only be started when the sensor after the corresponding spindle section meets the conditions for direct start-up, start-up by counter M1 or start-up by counter M2.

[0073] Therefore, the meaning of Table 2-3 is that under the condition of "two varieties being divided between two spindle sections", "single spindle start-up of a certain spindle section" requires the corresponding sensor after the spindle section to meet the conditions of direct start-up, count M1 start-up, or count M2 start-up, so as to realize the intelligent start-up of a single spindle of the automatic winding machine in the embodiment. Table 2-3 is a summary description of all cases of this embodiment based on the formula and Table 1.

[0074] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.

If there are any unstarted automatic winding machine spindles in the section, the corresponding automatic winding machine spindle in the section will be started. If all automatic winding machine spindles are started and running, no operation will be performed. Step 2: When the automatic winding machine controller controls the operation of a single spindle in the starting section, if the sensor after the spindle section is located in front of the yarn feeding direction of the inlet channel of the spindle section, the automatic winding machine controller controls the operation of the single spindle according to the single spindle direct start control logic; if the sensor after the spindle section is located behind the yarn feeding direction of the inlet channel of the spindle section, the automatic winding machine controller controls the operation of the single spindle according to the single spindle counting start control logic.

5. The control method for the intelligent start-stop control system of a single spindle for a dual-product automatic winding machine according to claim 4, characterized in that, In the single-spindle counting start control logic, the counting start threshold needs to be calculated based on the position of the sensor after the corresponding spindle section, the length of the spindle section, and the number of storage tubes after the single spindle. When the sensor after the corresponding spindle section is located at the head of the spindle section, the calculation formula for the counting start threshold is as shown in equation (1): (1) In the formula, M 1 represents the counting start threshold where the sensor position after the spindle section is located at the head of the spindle section; N 1 represents the length of the spindle section; N 2 represents the number of storage tubes after a single ingot is produced.
