Description

Technical Field

[0001] This invention relates to the field of winding machine technology, and in particular to a method and apparatus for obtaining the outline of the fork blades of the traverse mechanism of a winding machine. Background Technology

[0002] The traverse mechanism is a key component of high-speed winding machines for chemical fiber filaments, significantly impacting the winding process. There are two common types of traverse mechanisms: the slotted drum rabbit head type and the shift fork type. The shift fork type traverse mechanism offers advantages over the slotted drum rabbit head type, including lower rotational speed, less impact and friction, and lower noise, making it better suited to the needs of high-speed winding machines.

[0003] The two most important components of a fork-type traverse mechanism are the guide plate and the fork blades. The guide plate and fork blades work together to guide the yarn bundle to complete the lateral movement and ensure that the speed is as constant as possible during the traverse process and that the yarn bundle folds back quickly and with minimal oscillation during the reversing process. Among them, the fork blades are used to guide the yarn bundle to perform lateral movement, so their profile has a significant impact on the movement state of the yarn and the winding formation.

[0004] Currently, most commonly used guide fork mechanisms in the market employ guide fork blades from Barmag, Germany. There is a lack of domestically developed methods for obtaining the profile of guide fork blades. Furthermore, existing research contains limited theoretical design of guide fork traverse mechanisms. For imported guide fork blades, the methods for obtaining their profiles and design models are not fully understood, and no profile derivation or analysis has been conducted based on theoretical winding requirements.

[0005] Therefore, the above-mentioned prior art has at least the following technical problem: the prior art lacks a method for obtaining the outline of the fork blade of the traverse mechanism of the winding machine. Summary of the Invention

The outline of the fork blade includes three segments connected in sequence: the fork blade guide wire segment, the fork blade reversing segment, and the fork blade relay segment. The fork blade guide wire segment is straight, and the fork blade reversing segment and the fork blade relay segment are both curved.

[0091] This application provides a method and apparatus for obtaining the outline of the fork blades of the traverse mechanism of a winding machine, thereby filling the gap in the prior art where there is no method for obtaining the outline of the fork blades of the traverse mechanism of a winding machine.

[0092] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0093] Currently, the fork blades of the domestic fork-type wire guide mechanism mainly rely on imports, and there is a lack of theoretical understanding of the working mechanism of the fork blades. This application provides a method and apparatus for obtaining the contour line of the fork blades in the traverse mechanism of a winding machine. This provides a basic method for the independent design of the contour line of the fork blades in the traverse mechanism of a winding machine.

[0094] The basic structure of the fork-type wire guide mechanism in a winding machine is as follows: the paper tube for winding the wire is horizontally positioned, and the wire guide plate is horizontally positioned above the paper tube. Two forks are fitted at both ends of the wire guide plate, and under the action of the drive structure, the forks reciprocate along the wire guide plate (the axis of the paper tube) and deflect in the horizontal plane. The forward fork moves the wire from the right end to the left end of the wire guide plate, and then the reverse fork takes over at the left end, catches the wire, and moves the wire from the left end to the right end of the wire guide plate. This process is repeated, thus winding the wire around the entire paper tube. The two forks have the same structure; for ease of distinction, they are defined as the forward fork and the reverse fork according to their working nature.

[0095] The guide wire plate includes a guide wire segment in the middle and a left reversing segment and a right reversing segment located at the left and right ends of the guide wire segment and extending upward, respectively. The left reversing segment and the right reversing segment are connected to the guide wire segment in a continuous manner. The guide wire segment is arc-shaped, and the left reversing segment and the right reversing segment are both parabolic.

[0096] The shift fork consists of a shift fork body and a shift fork blade. The shift fork body is rectangular, and the shift fork blade is a ceramic plate bonded to one end of the shift fork body. According to the requirements of its guide wire function, during the movement of the wire bundle along the forward shift fork blade, the speed should be kept as constant as possible in the middle section of the guide stroke. In the guide reversal section, the auxiliary wire bundle should be decelerated in lateral movement and quickly folded back, and the relay should be realized with the reverse shift fork blade.

[0097] Therefore, based on the requirements of theoretical winding and guide wire function, the profile of the shift fork blade obtained in this embodiment is divided into three segments: guide wire segment (straight line segment), reversing segment (curved segment), and relay segment (curved segment). The guide wire segment is a straight line segment, extending smoothly along the edge of the shift fork body. The reversing segment and relay segment are both curved segments, and the curves are obtained by fitting key points.

[0098] Based on the principle of traverse guide wire, the key points corresponding to the profile of the shift fork blade are determined according to the theoretical winding requirements and the relevant parameters of the guide wire plate, and the profile of the shift fork blade is fitted.

[0099] The technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments and specific features in the embodiments are detailed descriptions of the technical solution of this application, rather than limitations thereof. In the absence of conflict, the embodiments and technical features in the embodiments can be combined with each other.

[0100] Example 1

[0101] Figure 1 This is a flowchart illustrating a method for obtaining the outline of the fork blades of a winding machine traverse mechanism provided in this embodiment. Figure 1 As shown, the method includes:

[0102] Step 100: Establish a coordinate system for the outline of the shift fork blade. Based on the relative positional relationship between the shift fork blade and the boundary point between the guide wire section and the left reversing section of the guide wire plate, and the starting reversing point of the shift fork on the guide wire plate during the working process, obtain the outline of the guide wire section of the shift fork blade.

[0103] Specifically, since the shift fork rotates continuously during operation while the guide plate remains stationary, the shift fork blade profile coordinate system PNQ is a sub-coordinate system established within the guide plate profile coordinate system XOY. Figure 2 This is a diagram showing the relationship between the coordinate system of the fork blade contour and the coordinate system of the guide plate contour.

[0104] Figure 2 In the diagram, D1 is the boundary between the guidewire section and the left commutation section of the guidewire plate; D2 is the boundary between the guidewire section and the right commutation section of the guidewire plate; D3 is the left end point of the left commutation section of the guidewire plate; and D4 is the right end point of the right commutation section of the guidewire plate. J D is the lowest point of the left commutation section of the guide wire plate. h1This is the starting point for the fork on the guide wire plate to reverse direction;

[0105] O is the origin of the guide plate contour coordinate system, O1 is the rotation center of the shift fork (set on the Y-axis in the XOY coordinate system), and N is the origin of the shift fork blade contour coordinate system.

[0106] a is the position where the shift fork blade begins to catch the wire on the guide plate; b is the position where the shift fork blade guides the wire to the center of the guide plate; c is the position where the shift fork blade, carrying the wire, begins to reverse direction on the guide plate; d is the position where the wire reverse direction ends (the point where the forward shift fork and the reverse shift fork take over).

[0107] Figure 3 The diagram shows a simplified mathematical model of the shift fork profile. The shift fork includes a shift fork body and shift fork blades. The shift fork body is rectangular and includes a left straight line segment 22 and a right straight line segment 21. The shift fork blades are bonded to one end of the shift fork body. The profile of the shift fork blades obtained in this embodiment is divided into three segments: the shift fork blade guide wire segment B1B2, the shift fork blade reversing segment B2B3, and the shift fork blade relay segment B3B4.

[0108] Among them, the guide wire section B1B2 of the shift fork blade is a straight line segment, located on the extension line of the right straight line segment 21 of the shift fork body. The shift fork blade reversing section B2B3 and the shift fork blade relay section B3B4 are both curved segments, which need to be obtained by fitting through key points.

[0109] Figure 3 In the diagram, B1 is the boundary point of the guide wire section of the shift fork blade, B2 is the dividing point between the guide wire section and the reversing section of the shift fork blade, B3 is the dividing point between the reversing section and the relay section of the shift fork blade, and B4 is the boundary point of the relay section of the shift fork blade. B4 is located on the left straight segment 22 of the shift fork body and is the end point of the left straight segment 22 of the shift fork body; e b This refers to the offset of the shift fork.

[0110] The core of this embodiment is to solve for the key coordinate points (B1, B2, B3, B4) in the outline model of the shift fork blade by determining the relative positional relationship between the shift fork blade and the outline of the guide plate during operation.

[0111] Furthermore, step 100 specifically includes:

[0112] Step 110: Establish a coordinate system with the origin N as the point of tangency between the extension of the shift fork guide wire segment and the shift fork rotation center circle, the vertical axis Q as the line connecting the origin N and the shift fork rotation center O1, and the horizontal axis P as the line passing through the origin N and perpendicular to the vertical axis Q. The shift fork rotation center circle is centered at the shift fork rotation center O1, and the shift fork eccentricity e... b A circle with radius .

[0113] Step 120: The guide wire section B1B2 of the shift fork blade is located on the horizontal axis P. The time when the shift fork blade guides the wire to the center of the guide plate is measured. Figure 2 The extreme radius ρ of the fork at position b) max And when the shift fork blades, carrying the wire, begin to change direction on the guide plate ( Figure 2 The polar radius ρ of the fork at position c) min Then we have:

[0114]

[0115] ρ min =R-y0

[0116] Where R is the radius of the arc of the guide wire section of the guide wire plate; y0 is the distance between the origin O of the guide wire plate contour coordinate system and the rotation center O1 of the shift fork blade; x D1 y D1 The coordinates of point D1, the dividing point between the guide wire section and the left reversing section of the guide wire plate, in the guide wire plate contour coordinate system;

[0117] The parameters related to the aforementioned wire guide plate, such as R and D1 coordinates, can be obtained based on the actual profile of the wire guide plate. For example, the applicant's patent 202310452420.2 provides a method and apparatus for obtaining the profile of a wire guide plate for a winding machine's fork-type wire guide mechanism, which also provides an exemplary method for obtaining the relevant parameters of the wire guide plate. y0 can be set according to the actual working conditions.

[0118] Step 130: Obtain the maximum sliding distance of the wire on the guide wire section of the shift fork blade, that is, the length Δ of the guide wire section B1B2 of the shift fork blade. The specific method is as follows:

[0119]

[0120] Among them, e b The offset of the shift fork can be set according to the actual working conditions.

[0121] Step 140: Obtain the coordinates of the boundary point B1 of the shift fork blade guide wire section, and the coordinates of the dividing point B2 between the shift fork blade guide wire section and the reversing section, and then obtain the outline of the shift fork blade guide wire section.

[0122] Specifically, by Figure 2 Given position b in the coordinate system, the position of point B2 in the coordinate system PNQ of the fork blade profile is obtained. The solution for the position coordinates of point B2 in the coordinate system PNQ of the fork blade profile is as follows:

[0123]

[0124]

[0125] Where, x B2cy B2c When point B2 on the shift fork blade is at the position where the shift fork blade, carrying the wire, begins to change direction on the guide plate ( Figure 2 The coordinates of position c in the XOY coordinate system of the guide plate contour line.

[0126] Specifically, the outline of the guide plate can be obtained from its actual profile. The applicant's patent 202310452420.2 provides a method and apparatus for obtaining the outline of a guide plate in a winding machine's fork-type guide mechanism, and also provides an exemplary method for obtaining relevant parameters of the guide plate. According to the description therein, assuming that point B2 at position c coincides with the outline of the guide plate, then:

[0127]

[0128] y B2c =p1x B2c 2 +p2x B2c +p3

[0129] Where H is the winding width set according to production requirements, e is the distance between the rotation center of the concentric shift fork and the rotation center of the eccentric shift fork, and p1, p2, and p3 are the equation coefficients of the left reversing section of the guide plate.

[0130] Combining step 100, the coordinates of point B1 can be obtained as follows:

[0131]

Specifically, D... J The coordinates of D3 can be obtained based on the actual profile of the guide plate. For example, the applicant's patent 202310452420.2 provides a method and device for obtaining the profile of the guide plate of the winding machine fork-type guide mechanism.

[0140] Step 300: Based on the relative positional relationship between the shift fork blades and the starting reversal point of the shift fork on the guide wire plate during operation, and based on the inclination angle β of the relay section of the shift fork blades... j and length l j Obtain the length l of the reversing section of the shift fork blade. h and height w h ;

[0141] In the coordinate system PNQ of the shift fork blade profile, the length l of the shift fork blade reversing segment is... h The length of the projection of the line connecting points B2 and B3 onto the Q-axis represents the height w of the reversing section of the shift fork blade. h This represents the length of the projection of the line connecting points B2 and B3 onto the P-axis, specifically as shown below. Figure 5 As shown. The length l of the reversing section of the shift fork blade. h and height w h The specific calculation method is as follows:

[0142] w h =2e b -l j *tanβ j

[0143] Set at the end of the wire reversal ( Figure 2 When in position d), the coordinates of point B2 on the fork blade in the XOY coordinate system of the guide plate contour are (x B2d y B2d Solve the following system of equations x B2d The solution corresponding to <0 yields x. B2d y B2d ;

[0144]

[0145] Among them, l O1Dh1 Representing O1 and D h1 The straight-line distance between two points;

[0146]

[0147]

[0148] The length l of the reversing section of the shift fork blade can be obtained using the formula above. h .

[0149] Step 400, based on the inclination angle β of the relay section of the shift fork blade j and length l j And the length l of the reversing section of the shift fork blade h and height w h Obtain the coordinates of points B3 and B4 in the coordinate system PNQ of the fork blade outline.

[0150] P B3 =P B2 +l h

[0151] Q B3 =Q B2 +w h

[0152] P B4 =P B3 -l j cosβ j

[0153] Q B4 =Q B3 +l j sinβ j

[0154] The coordinates of points B3 and B4 can be obtained using the formula above.

[0155] Step 500: Based on the coordinates of key coordinate points B1, B2, B3, and B4 in the fork blade profile model, a Bezier curve is used for fitting to obtain the profiles of the fork blade reversing section and the fork blade relay section.

[0156] Specifically, based on the above steps, the theoretical coordinates of the key points of the shift fork blade profile—the starting point B2 of the shift fork blade reversing segment, the ending point B3 (the starting point of the shift fork blade relay segment), and the ending point B4 of the shift fork blade relay segment—were determined. Now, according to actual motion requirements, the shift fork blade reversing segment and the shift fork blade relay segment need to be fitted into a curve, as shown below. Figure 6 As shown.

[0157] Since points B2, B3, and B4 are fixed, the curve should pass through these three points during fitting; the slope of the line connecting points B3 and B4 is fixed, the slope at point B2 is 0, and the slope at point B3 is perpendicular to the P-axis; therefore, the following constraints can be listed:

[0158]

[0159] Where, k B3B4 This represents the slope of the line connecting points B3 and B4 in the PNQ coordinate system.

[0160] Taking into account both constraints and smoothness / continuity, a Bezier curve was used for fitting.

[0161] Based on the properties of Bézier curves, the key points of the shift fork blade are selected by splicing quadratic and cubic Bézier curves, resulting in a total of seven control points. Since the two control points coincide at the splicing points, the coordinate positions of six points need to be considered. The rules for selecting control points, corresponding to the coordinate system of the shift fork blade profile, are as follows:

[0162] The curve starting point P1 is set as the starting point B1 of the reversing section of the shift fork blade, which is a fixed point;

[0163] The endpoint of the curve, P6, is designated as the endpoint of the relay segment of the shift fork blade, B4, which is a fixed point.

[0164] The splicing point P3 (P4) is the end point of the reversing section of the shift fork blade (the starting point of the relay section of the shift fork blade) B3, which is a fixed point;

[0165] Since P2, P3(P4), and P5 are collinear, P2 is a fixed point such that P1P2⊥P2P3.

[0166] Since P2, P3 (P4), and P5 are collinear, in order to make the relay segment as straight as possible, P5 must be as close as possible to P3 (P4).

[0167] P6 must satisfy the condition that the slope of the line connecting P5 and P6 is equal to the slope of the inclination angle of the relay segment. At the same time, in order to make the relay segment as straight as possible, P5 must be as close as possible to P4.

[0168] Experimental verification:

[0169] Taking a certain imported winding machine and its corresponding theoretical winding parameters as an example, the outline of the shift fork blade is calculated using the method described in the embodiments of this application, and compared with the actual outline of the shift fork blade of the imported winding machine to prove the effectiveness of the method.
