Description

Technical Field

[0001] This invention relates to the field of fiber winding processing technology, and in particular to a method, apparatus, electronic device and storage medium for trimming a winding machine based on region division. Background Technology

[0002] A high-speed winding machine is a specialized piece of equipment used for winding long filaments such as silk and chemical fibers. Its main function is to neatly wind continuous filaments from a reeling machine or spinning machine onto a bobbin under specific tension, speed, and winding pattern, forming a bobbin (also called a "silk cake") that facilitates subsequent unwinding and processing. During the bobbin (silk cake) forming process on a high-speed winding machine (or winding machine), "trimming" refers to tidying the edges of both ends of the wound bobbin to ensure a neat, lint-free, and smooth finish, free from sagging or protrusions. This ensures smooth unwinding, reduces breakage, and improves the product's appearance quality.

[0003] The existing traditional winding machine trimming mainly modifies the position parameters of the reversing point while the equipment is running (i.e. during winding), which can cause the current stroke to be interrupted, disordered or incomplete, which may cause winding defects (such as tangled wires, overlapping wires, uneven edges, etc.). Summary of the Invention

[0004] To address the problems existing in the prior art, this specification describes one or more embodiments of a wire winding machine trimming method, apparatus, electronic device, and storage medium based on region division.

[0005] According to the first aspect, a trimming method for a winding machine based on region division is provided, the method comprising:

[0006] The yarn bobbin is divided into a stable zone and a first edge zone and a second edge zone on both sides of the stable zone. When the yarn guide moves in the stable zone, the motor speed corresponding to the stable zone is collected, and the diameter corresponding to the stable zone is calculated based on the motor speed corresponding to the stable zone.

[0007] The yarn guide moves from the stable area to the first edge area along the first direction, collects the motor speed corresponding to the first edge area, calculates the diameter corresponding to the first edge area based on the motor speed corresponding to the first edge area, calculates the top reversal position based on the diameter corresponding to the stable area and the diameter corresponding to the first edge area, and updates the top reversal position when the yarn guide moves along the second direction.

[0008] The yarn guide moves from the stable area to the second edge area along the second direction, collects the motor speed corresponding to the second edge area, calculates the diameter corresponding to the second edge area based on the motor speed corresponding to the second edge area, calculates the bottom reversal position based on the diameter corresponding to the stable area and the diameter corresponding to the second edge area, and updates the bottom reversal position when the yarn guide moves along the first direction.

[0009] Preferably, the step of calculating the diameter corresponding to the first edge region based on the motor speed corresponding to the first edge region includes:

[0015] If the diameter sequence corresponding to the first edge region has a sudden increase in peak value, and the yarn tension is greater than a set tension threshold, then the trimming state corresponding to the first edge region is characterized by a protrusion. If the diameter sequence corresponding to the first edge region continues to decrease, and the deviation value is greater than a set tolerance threshold, then the trimming state corresponding to the first edge region is characterized by an outward protrusion. If the diameter sequence corresponding to the first edge region does not have a sudden increase in peak value, and the yarn tension is less than a set tension threshold, then the trimming state corresponding to the first edge region is characterized by a stable trimming.

[0016] Preferably, calculating the position of the top reversal point based on the trimming state includes:

[0017] If the trimming state corresponding to the first edge area is that there are protrusions, then the top reversal position moves along the axis of the yarn bobbin towards the direction closer to the stable area;

[0018] If the trimming state corresponding to the first edge area is outward protrusion, then the top reversal position moves away from the stable area along the axial direction of the yarn bobbin.

[0019] Preferably, the top reversal position is the boundary position of the first edge region away from the stable region along the axial direction of the yarn bobbin.

[0020] Preferably, a first interval is provided between the stable region and the first edge region.

[0021] According to a second aspect, a trimming device for a winding machine based on region division is provided, the device comprising:

[0022] The diameter reference calculation module is used to divide the yarn bobbin along the axial direction into a stable zone and a first edge zone and a second edge zone located on both sides of the stable zone. When the yarn guide moves in the stable zone, it collects the motor speed corresponding to the stable zone and calculates the diameter corresponding to the stable zone based on the motor speed corresponding to the stable zone.

[0023] The top reversal position calculation module is used to move the yarn guide from the stable area to the first edge area along the first direction, collect the motor speed corresponding to the first edge area, calculate the diameter corresponding to the first edge area based on the motor speed corresponding to the first edge area, calculate the top reversal position based on the diameter corresponding to the stable area and the diameter corresponding to the first edge area, and update the top reversal position when the yarn guide moves along the second direction.

[0024] The bottom reversal position calculation module is used to move the yarn guide from the stable area to the second edge area along the second direction, collect the motor speed corresponding to the second edge area, calculate the diameter corresponding to the second edge area based on the motor speed corresponding to the second edge area, calculate the bottom reversal position based on the diameter corresponding to the stable area and the diameter corresponding to the second edge area, and update the bottom reversal position when the yarn guide moves along the first direction.

[0025] According to a third aspect, an electronic device is provided, including a processor and a memory;

[0026] The processor is connected to the memory;

[0027] The memory is used to store executable program code;

[0030] The beneficial effects of this invention are as follows:

[0031] 1. The method and apparatus provided in the embodiments of this specification update the position each time a new reversing position is calculated, ensuring that the adjustment of the reversing point position does not interfere with the stability of the current stroke, avoiding winding defects and improving the appearance quality of the product.

[0032] 2. The method and apparatus provided in the embodiments of this specification calculate the position of each reversal point by using the diameter sequence corresponding to each edge area. This not only determines whether there is a problem, but also evaluates the severity level through indicators such as peak height, number of continuous layers, and symmetry to optimize the trimming of the winding machine and improve the appearance quality of the product.

[0033] 3. The method and apparatus provided in the embodiments of this specification have a first gap between the stable region and the first edge region. When the first edge region is poorly formed (such as with an upper protrusion), the first gap reduces the impact of the poorly formed first edge region (such as with an upper protrusion) on the tension data of the stable region, thereby avoiding error transmission.

[0041] See Figure 1 , Figure 1 This is a schematic flowchart of a wire winding machine trimming method based on region division provided in an embodiment of this application. In this embodiment, the method includes:

[0042] S101. Divide the yarn bobbin along the axial direction into a stable zone and a first edge zone and a second edge zone located on both sides of the stable zone. When the yarn guide moves in the stable zone, collect the motor speed corresponding to the stable zone and calculate the diameter corresponding to the stable zone based on the motor speed corresponding to the stable zone.

[0043] S102. The yarn guide moves from the stable area to the first edge area along the first direction, collects the motor speed corresponding to the first edge area, calculates the diameter corresponding to the first edge area based on the motor speed corresponding to the first edge area, calculates the top reversal position based on the diameter corresponding to the stable area and the diameter corresponding to the first edge area, and updates the top reversal position when the yarn guide moves along the second direction.

[0044] S103. The yarn guide moves from the stable area to the second edge area along the second direction, collects the motor speed corresponding to the second edge area, calculates the diameter corresponding to the second edge area based on the motor speed corresponding to the second edge area, calculates the bottom reversal position based on the diameter corresponding to the stable area and the diameter corresponding to the second edge area, and updates the bottom reversal position when the yarn guide moves along the first direction.

[0045] The entity executing this application may be the winding machine control unit.

[0046] In this embodiment, the yarn bobbin is divided axially into a stable region, a first edge region, and a second edge region. The first and second edge regions are located on opposite sides of the stable region along the yarn bobbin's axial direction. The yarn guide reciprocates axially along the yarn bobbin. The directions of movement of the yarn guide are denoted as the first direction and the second direction. When the yarn guide moves along the first direction, it passes through the stable region. The motor speed corresponding to the stable region is then collected, and the diameter corresponding to the stable region is calculated based on the motor speed. The yarn guide then moves through the stable region to the first edge region. When the yarn guide is in the first edge region, the motor speed corresponding to the first edge region is collected, and the diameter corresponding to the first edge region is calculated based on the motor speed. The top reversal position is calculated based on the diameters of the stable region and the first edge region, and this top reversal position is buffered. When the yarn guide moves to the top reversal position, a reversal occurs. The yarn guide moves along a second direction, passing through a stable zone. The motor speed corresponding to this stable zone is then collected, and the diameter of the stable zone is calculated based on this speed. The yarn guide then moves through the stable zone to the second edge zone. While in the second edge zone, the motor speed corresponding to this edge zone is collected, and the diameter of the second edge zone is calculated based on this speed. The bottom reversal position is calculated using both the diameter of the stable zone and the diameter of the second edge zone, and this bottom reversal position is cached. When the yarn guide reaches the bottom reversal position, it reverses direction. The yarn guide then moves along the first direction, updating the previously calculated top reversal position. When the yarn guide reaches the updated top reversal position, it reverses direction, and the previously calculated bottom reversal position is updated again. In this application, each time a new reversal position is calculated, it is updated in the next stroke, ensuring that adjustments to the reversal point position do not interfere with the stability of the current stroke, avoiding winding defects, and improving the product's appearance quality.

[0047] In one possible implementation, calculating the diameter corresponding to the first edge region based on the motor speed corresponding to the first edge region includes:

[0048] Collect the single-turn winding time series corresponding to the first edge region, calculate the diameter sequence corresponding to the first edge region based on the single-turn winding time series corresponding to the first edge region, and calculate the diameter corresponding to the first edge region based on the diameter sequence.

[0049] In the embodiments of this specification, during the movement of the yarn guide in the stable zone, the winding time per turn is collected by sensors and other devices to obtain the unit winding time sequence corresponding to the stable zone. Then, the diameter of the meter wheel is obtained, and the diameter sequence corresponding to the stable zone is calculated according to the diameter calculation formula. The diameter calculation expression is as follows:

[0050]

[0051] in, This represents the diameter sequence corresponding to the stable region. Indicates the diameter of the measuring wheel. This indicates the motor speed corresponding to the stable region. This represents the unit winding time series corresponding to the stable region.

[0052] After obtaining the diameter sequence corresponding to the stable region, the mean is calculated to obtain the diameter corresponding to the stable region. Similarly, the diameters of the first edge region and the second edge region can be calculated in the same way.

[0053] In one possible implementation, calculating the top reversal position based on the diameter corresponding to the stable region and the diameter corresponding to the first edge region includes:

[0054] The trimming state is obtained based on the diameter corresponding to the first edge region, the diameter sequence, and the diameter corresponding to the stable region. The position of the top reversal point is calculated based on the trimming state.

[0055] In the embodiments of this specification, the trimming state of the winding machine in the first edge region is determined based on the diameter sequence and diameter corresponding to the first edge region, and the diameter corresponding to the stable region. Then, the position of the top reversal point is calculated based on the trimming state of the winding machine in the first edge region. Similarly, the trimming state of the winding machine in the second edge region can be determined based on the diameter sequence and diameter corresponding to the second edge region, and the position of the top reversal point is calculated based on the trimming state of the winding machine in the second edge region. This application calculates the position of each reversal point using the diameter sequence corresponding to each edge region. This not only determines whether there is a problem, but also assesses the severity level through indicators such as peak height, number of continuous layers, and symmetry to optimize the trimming of the winding machine and improve the appearance quality of the product.

[0056] In one possible implementation, the trimming state includes the presence of a convex point, outward protrusion, and stable trimming. The step of obtaining the trimming state based on the diameter corresponding to the first edge region, the diameter sequence, and the diameter corresponding to the stable region includes:

[0057] Obtain the yarn tension and calculate the deviation between the diameter corresponding to the first edge region and the diameter corresponding to the stable region;

[0058] If the diameter sequence corresponding to the first edge region has a sudden increase in peak value, and the yarn tension is greater than a set tension threshold, then the trimming state corresponding to the first edge region is characterized by a protrusion. If the diameter sequence corresponding to the first edge region continues to decrease, and the deviation value is greater than a set tolerance threshold, then the trimming state corresponding to the first edge region is characterized by an outward protrusion. If the diameter sequence corresponding to the first edge region does not have a sudden increase in peak value, and the yarn tension is less than a set tension threshold, then the trimming state corresponding to the first edge region is characterized by a stable trimming.

[0059] In the embodiments of this specification, yarn tension is acquired, and the deviation value between the diameter corresponding to the first edge region and the diameter corresponding to the stable region is calculated. The deviation value is the absolute value of the difference between the diameter corresponding to the first edge region and the diameter corresponding to the stable region. If there is a sudden increase in the peak value of the diameter sequence corresponding to the first edge region, that is, there is a point in the diameter sequence corresponding to the first edge region whose diameter is larger than that of the adjacent point, and the yarn tension is greater than a set tension threshold, then the trimming state corresponding to the first edge region is characterized by a convex point. If the diameter sequence corresponding to the first edge region continues to decrease, and the deviation value is greater than a set tolerance threshold, then the trimming state corresponding to the first edge region is characterized by an outward edge protrusion. If there is no sudden increase in the peak value of the diameter sequence corresponding to the first edge region, and the yarn tension is less than a set tension threshold, then the trimming state corresponding to the first edge region is characterized by a stable trimming. Similarly, the correction state detection of the second edge region can be performed in the same manner.

[0060] In one possible implementation, calculating the position of the top reversal point based on the trimming state includes:

[0061] If the trimming state corresponding to the first edge area is that there are protrusions, then the top reversal position moves along the axis of the yarn bobbin towards the direction closer to the stable area;

[0062] If the trimming state corresponding to the first edge area is outward protrusion, then the top reversal position moves away from the stable area along the axial direction of the yarn bobbin.

[0063] In the embodiments of this specification, if the trimming state corresponding to the first edge area is characterized by the presence of protrusions, the top reversal position is moved along the axial direction of the yarn bobbin towards the stable area; if the trimming state corresponding to the first edge area is characterized by outward protrusion, the top reversal position is moved along the axial direction of the yarn bobbin away from the stable area; if the trimming state corresponding to the first edge area is characterized by stable trimming, the top reversal position is maintained. Similarly, the bottom reversal position of the second edge area can be updated in the same manner.

[0064] In one possible implementation, the top reversal position is the boundary position of the first edge region away from the stable region along the axial direction of the yarn bobbin.

[0065] In the embodiments described in this specification, the top reversal position is the boundary position of the first edge region away from the stable region along the axial direction of the yarn bobbin, and the bottom reversal position is the boundary position of the second edge region away from the stable region along the axial direction of the yarn bobbin.

[0066] In one possible implementation, a first interval is provided between the stable region and the first edge region.

[0067] In the embodiments of this specification, a first gap is provided between the stable region and the first edge region, and a second gap is provided between the stable region and the second edge region. For example: Stable region: bottom position = 15, top position = 125. First edge region: bottom position = 130, top position = 140. Second edge region: top position = 10, bottom position = 0. In this application, the first gap between the stable region and the first edge region reduces the impact of poor forming (such as an upper protrusion) on the tension data of the stable region, thus avoiding error propagation, when the first edge region has poor forming (such as an upper protrusion).
