Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of textile equipment, and relates to a rotary three-dimensional braider based on a linkage control mode. BACKGROUND

[0002] The rotary three-dimensional braider drives the yarn carrier by introducing an angle wheel mechanism to realize the regular transfer of yarn in three-dimensional space. In order to realize the maximum yarn carrier capacity and fully load the yarn, the rotary three-dimensional braider adopts step-by-step movement (that is, when any angle wheel rotates, the surrounding angle wheels must remain stationary), and is equipped with an independent control step motor for each angle wheel, so that each step motor can be independently controlled, thereby realizing the maximum degree of automation control of the braider.

[0003] However, the above processing scheme can maximize the control of the angle wheel, but the control cost of the motor is too high, and with the use of a large number of step motors, the control difficulty and huge electric power load of the motor greatly restrict the development of this technology, so it still remains in the laboratory stage. For example, the rotary three-dimensional braider disclosed in the patents with the publication numbers CN114990779B, CN114990778B and CN115287819B and document 1 (Rotary Three-Dimensional Braider Design Method Based on the Average Cutting Circle Strategy[J]. Engineering, 2025, 49(000): 260-271.) has each angle wheel connected with a step motor.

[0004] To solve the above problems, document 2 (Design optimization of a three-dimensional hexagonal braiding technique[J]. Textile Research Journal, 2024, 95(7-8): 688-704.) constructs a rotary three-dimensional braider formed by a combination of six angle wheels and three angle wheels, which reduces the motor power by adopting a series of optimization methods, but the finally built braider can only independently drive 19 angle wheels, which also shows that the method of using step motors to drive angle wheels limits the machine scale.

[0005] Therefore, it is necessary to provide a rotary three-dimensional braider based on a linkage control mode, and to realize independent control of the angle wheel through simple clutch control on the basis of linkage control, to retain the independent control characteristics of the rotary braider while reducing the control difficulty and power consumption, so as to solve the above problems, which has very important significance. SUMMARY

[0006] The present application aims to solve the problems existing in the prior art, and provides a rotary three-dimensional braiding machine based on a linkage control mode.

[0007] To achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:

[0008] A rotary three-dimensional braiding machine based on a linkage control mode (denoted as rotary three-dimensional braiding machine A) comprises a yarn carrier, an intermittent driving device, m horizontally arranged angle wheels, and m vertically arranged transmission shafts, m≥2, the m angle wheels are respectively fixed at the top of the m transmission shafts, all the angle wheels are divided into n groups, n≥2, the angle wheels in the same group rotate 360° to sweep a region which does not overlap and synchronously rotates, and the angle wheels in different groups do not synchronously rotate;

[0009] The m transmission shafts are divided into two groups, one group has n transmission shafts, denoted as transmission shaft A, and the other group has (m-n) transmission shafts, denoted as transmission shaft B;

[0010] The intermittent driving device comprises n Geneva mechanisms and a motor;

[0011] Each Geneva mechanism comprises a horizontally arranged dial as a driving member and a horizontally arranged Geneva wheel as a driven member;

[0012] The n Geneva mechanisms are arranged in sequence from bottom to top, the output shaft of the motor is vertically arranged and simultaneously penetrates the center of the dial of the n Geneva mechanisms and is fixedly connected therewith; when the motor works, the Geneva wheels of the n Geneva mechanisms rotate individually in sequence;

[0013] The n transmission shafts A respectively penetrate the center of the Geneva wheels of the n Geneva mechanisms and are fixedly connected therewith;

[0014] Each transmission shaft A is sleeved with one driving gear and (n-1) driven gears, the driving gear is fixedly connected with the transmission shaft A, and the driven gears are rotationally connected with the transmission shaft A;

[0015] Each transmission shaft B is sleeved with one driving gear and (n-1) driven gears, the driving gear is fixedly connected with the transmission shaft B, and the driven gears are rotationally connected with the transmission shaft B;

[0016] The driving gear on the i-th transmission shaft A, one driven gear on each other transmission shaft A, the driving gear on the transmission shaft B below the other angle wheels in the same group as the angle wheel on the i-th transmission shaft A, and one driven gear on each other transmission shaft B are coplanar, forming a transmission gear set with the driving gear on the i-th transmission shaft A as a power source, i=1, 2,..., n.

[0017] When the motor works, the grooved wheels of the n grooved wheel mechanisms rotate separately in turn, since "n transmission shafts A respectively pass through the centers of the grooved wheels of the n grooved wheel mechanisms and are fixedly connected with the grooved wheels", thus the n transmission shafts A rotate separately in turn, and since "the driving gears are fixedly connected with the transmission shafts A", thus the driving gears on the n transmission shafts A rotate separately in turn.

[0018] When the i-th transmission shaft A and the driving gear thereon rotate, the i-th group of angle wheels rotates, for the following reasons:

[0019] Since "the m angle wheels are respectively fixed on the top of the m transmission shafts", thus the angle wheels on the i-th transmission shaft A rotate;

[0020] Since "the driving gear on the i-th transmission shaft A, one driven gear on each of the other transmission shafts A, the driving gear on the transmission shaft B below the other angle wheels in the same group with the angle wheels on the i-th transmission shaft A, and one driven gear on each of the other transmission shafts B are coplanar, forming a transmission gear set with the driving gear on the i-th transmission shaft A as the power source, i=1, 2,..., n", thus the driving gear on the transmission shaft B below the other angle wheels in the same group with the angle wheels on the i-th transmission shaft A rotates, and since "the driving gear is fixedly connected with the transmission shaft B", thus the transmission shaft B below the other angle wheels in the same group with the angle wheels on the i-th transmission shaft A rotates, and since "the m angle wheels are respectively fixed on the top of the m transmission shafts", thus the other angle wheels in the same group with the angle wheels on the i-th transmission shaft A rotate.

[0021] The application also provides another rotary three-dimensional braiding machine based on linkage control mode (denoted as rotary three-dimensional braiding machine B), which comprises a yarn carrier, an intermittent driving device, m horizontally arranged angle wheels and m vertically arranged transmission shafts, m≥2, the m angle wheels are respectively fixed on the top of the m transmission shafts, all the angle wheels are divided into n groups, n≥2, the angle wheels in the same group rotate synchronously and the angle wheels in different groups rotate asynchronously;

[0022] The intermittent driving device comprises n grooved wheel mechanisms, a motor and n vertically arranged support shafts;

[0023] Each grooved wheel mechanism comprises a horizontally arranged dial as a driving member and a horizontally arranged grooved wheel as a driven member;

[0024] The n grooved wheel mechanisms are arranged in turn from bottom to top, the output shaft of the motor is vertically arranged and simultaneously passes through the centers of the dials of the n grooved wheel mechanisms and is fixedly connected with the dials; when the motor works, the grooved wheels of the n grooved wheel mechanisms rotate separately in turn;

[0025] The n support shafts respectively pass through the centers of the grooved wheels of the n grooved wheel mechanisms and are fixedly connected with the grooved wheels;

[0026] A driving gear and (n-1) driven gears are sleeved on each transmission shaft, the driving gear is fixedly connected with the transmission shaft, and the driven gears are rotationally connected with the transmission shaft;

[0027] A driving gear and (n-1) driven gears are sleeved on each transmission shaft, the driving gear is fixedly connected with the transmission shaft, and the driven gears are rotationally connected with the transmission shaft;

[0028] The driving gear below the i th group of angle wheels and the driven gear below each other angle wheel are coplanar, forming a transmission gear set with the driving gear on the i th support shaft as a power source, i = 1, 2,..., n.

[0029] When the motor works, the grooved wheels of the n-grooved wheel mechanisms rotate in turn, and since "n support shafts pass through the centers of the grooved wheels of the n-grooved wheel mechanisms and are fixedly connected therewith", the n support shafts rotate in turn. Since "the driving gears are fixedly connected with the transmission shafts", the driving gears on the n support shafts rotate in turn.

[0030] When the i th support shaft and the driving gear thereon rotate, the i th group of angle wheels rotates, because:

[0031] Since "the driving gear below the i th group of angle wheels and the driven gear below each other angle wheel are coplanar, forming a transmission gear set with the driving gear on the i th support shaft as a power source, i = 1, 2,..., n", the driving gear below the i th group of angle wheels rotates, and since "the driving gears are fixedly connected with the transmission shafts", the transmission shaft on which the driving gear below the i th group of angle wheels is located rotates, and since "m angle wheels are fixedly connected to the top of m transmission shafts", the i th group of angle wheels rotates.

[0034] In rotary three-dimensional knitting machine A* and rotary three-dimensional knitting machine B*, the dial includes a dial plate and a dial pin vertically set on the dial plate; the grooved wheel is a rotating disk with radially evenly distributed radiating transmission grooves, and the thickness surface of the rotating disk is composed of at least the groove wall of each transmission groove and multiple concave arc surfaces; when the dial rotates around its own central axis, it drives the dial pin to engage in the transmission groove, driving the grooved wheel to rotate around its own central axis.

[0035] In rotary 3D braiding machines A** and B**, within the same Geneva mechanism, such as... Figure 8 As shown in Figure a, the dial has 1 pin and the Geneva wheel has 3 drive grooves, with an intermittent rotation angle of 120°; or, the dial has 2 pins and the Geneva wheel has 3 drive grooves, with an intermittent rotation angle of 240°; Figure 8 As shown in b, either the dial has 1 pin, the Geneva wheel has 4 drive grooves, and the intermittent rotation angle is 90°; or the dial has 2 pins, the Geneva wheel has 4 drive grooves, and the intermittent rotation angle is 180°. Figure 12 As shown in Figure a, either the number of pins on the dial is 1, the number of drive grooves on the Geneva wheel is 6, and the intermittent rotation angle is 60°; or the number of pins on the dial is 2, the number of drive grooves on the Geneva wheel is 6, and the intermittent rotation angle is 120°; Figure 12 As shown in b, either the number of pins on the dial is 1, the number of transmission grooves on the Geneva wheel is 8, and the intermittent rotation angle is 45°; or the number of pins on the dial is 2, the number of transmission grooves on the Geneva wheel is 8, and the intermittent rotation angle is 90°.

[0036] In rotary three-dimensional braiding machines A*** and B***, among the n Geneva mechanisms, the number of pins on the dial of the i-th Geneva mechanism is r. i The number of transmission slots on the Geneva wheel in the i-th Geneva mechanism is s. i i = 1, 2, ..., n, n, r i s i The relationship satisfies the following formula:

[0037]

[0038] Based on the above formula, it can be calculated whether each Geneva wheel can be combined to form an intermittent output mechanism, that is, to determine whether each Geneva wheel can achieve intermittent motion without interference.

[0039] In rotary 3D braiding machines A**** and B****, n = 2, r1 = 1, s1 = 3, r2 = 1, s2 = 3 (applicable to type 3-3 braiding machines, i.e., braiding machines where any two adjacent corner wheels are triangular wheels), or r1 = 1, s1 = 3, r2 = 2, s2 = 4 (applicable to type 3-2 braiding machines, i.e., braiding machines where any two adjacent corner wheels are a triangular wheel and a diagonal wheel), or r1 = 1, s1 = 3, r2 = 1, s2 = 4 (applicable to type 3-4 braiding machines). This refers to braiding machines where one of any two adjacent corner wheels is a triangular wheel and the other is a square wheel; or r1 = 1, s1 = 3, r2 = 1, s2 = 8 (applicable to type 3-8 braiding machines, where one of any two adjacent corner wheels is an octagonal wheel and the other is a triangular wheel); or r1 = 2, s1 = 4, r2 = 1, s2 = 6 (applicable to type 6-2 braiding machines, where one of any two adjacent corner wheels is a hexagonal wheel and the other is a diagonal wheel); or r1 = 2, s1 = 6, r2 = 1, s2 = 6 (applicable to braiding machines such as...). Figure 19 The 6-3 type braiding machine shown refers to a braiding machine where one of any two adjacent corner wheels is a hexagonal wheel and the other is a triangular wheel; or r1 = 1, s1 = 6, r2 = 1, s2 = 4 (applicable to the 6-4 type braiding machine, which refers to a braiding machine where one of any two adjacent corner wheels is a hexagonal wheel and the other is a square wheel); or as shown... Figure 6 As shown, r1 is 1, s1 is 4, r2 is 1, and s2 is 4 (applicable to cases such as...). Figure 18 The 4-4 type braiding machine shown is a braiding machine where any two adjacent corner wheels are four-corner wheels; or r1 = 1, s1 = 4, r2 = 2, s2 = 4 (applicable to the 4-2 type braiding machine, where any two adjacent corner wheels are one four-corner wheel and the other two-corner wheel); or r1 = 1, s1 = 4, r2 = 1, s2 = 8 (applicable to the 4-8 type braiding machine, where any two adjacent corner wheels are one four-corner wheel and the other eight-corner wheel); or r1 = 1, s1 = 8, r2 = 1, s2 = 8 (applicable to the 8-8 type braiding machine, where any two adjacent corner wheels are eight-corner wheels).

[0040] Alternatively, n=3, r1 is 1, s1 is 6, r2 is 1, s2 is 6, r3 is 1, and s3 is 6 (applicable to 6-6 type braiding machines, i.e. braiding machines where any two adjacent corner wheels are hexagonal wheels).

[0041] Or, such as Figure 7 As shown, n=4, r1 is 1, s1 is 4, r2 is 1, s2 is 4, r3 is 1, s3 is 4, r4 is 1, s4 is 4 (applicable to multi-step intermittent 4-4 type braiding machines, i.e. braiding machines where any two adjacent corner wheels are either four-corner wheels or four-corner wheels).

[0042] Alternatively, n=6, r1 is 1, s1 is 3, r2 is 1, s2 is 3, r3 is 1, s3 is 3, r4 is 1, s4 is 3, r5 is 1, s5 is 3, r6 is 1, s6 is 3 (applicable to 3-3 type braiding machines that require multiple intermittent steps, i.e., braiding machines where any two adjacent corner wheels are either triangular wheels or triangular wheels).

[0043] In rotary three-dimensional knitting machine A** and rotary three-dimensional knitting machine B**, the dial also includes a positioning plate. The thickness surface of the positioning plate is composed of a convex arc surface and at least one concave arc surface. The positioning plate is located above the dial, and the two are coaxial and fixedly connected. The convex arc surface of the positioning plate can be rotated to fit against the concave arc surface of the rotary disk. At this time, the grooved wheel is braked and is in an intermittent state.

[0044] In the rotary three-dimensional braiding machine B*, each drive shaft is fitted with ceil(n / 2) supplementary gears, where ceil() represents rounding up. The supplementary gears are rotatably connected to the drive shaft.

[0045] The middle section of each of the m drive shafts consists of an inner shaft and a sliding sleeve. The surface of the inner shaft is provided with a slide rail, and the inner surface of the sliding sleeve is provided with a protrusion. The sliding sleeve is fitted onto the inner shaft and is slidably connected to the inner shaft in the vertical direction through the slide rail and the protrusion.

[0046] The sliding sleeve is fixedly fitted with (n-1) + ceil(n / 2) bearings, and a key is fixedly provided. (n-1) driven gears are fixedly fitted on (n-1) bearings respectively, and ceil(n / 2) supplementary gears are fixedly fitted on ceil(n / 2) bearings respectively. The key is embedded in the inner wall of the drive gear.

[0047] A ring is fixedly fitted at the bottom of the sliding sleeve. The ring is fixedly connected to a vertically arranged rod, which is fixedly connected to the shaft of a cylinder.

[0048] After the sliding sleeve slides a certain distance relative to the inner shaft, the drive gear on the sliding sleeve disengages from the transmission gear set, and ceil(n / 2) replacement gears fill the gaps in each transmission gear set at this time.

[0049] In rotary three-dimensional knitting machine A* and rotary three-dimensional knitting machine B*, the yarn carrier includes an elliptical block, a cylindrical shaft and a cylindrical block connected coaxially from top to bottom. The thickness of the elliptical block is t, the diameter of the cylindrical shaft is d, the height of the cylindrical shaft is h, and the diameter of the cylindrical block is greater than d.

[0050] Each drive shaft passes through the center of a circular protrusion and is fixedly connected to it; on the same drive shaft, the circular protrusion is located below the corner wheel and at a distance t from the upper surface of the corner wheel. The diameter of the circular protrusion is smaller than that of the corner wheel, the thickness of the circular protrusion is equal to h, and the circular protrusion is located above each gear.

[0051] The method for determining the diameter of a circular bump is as follows:

[0052] In the top view of the corner wheels, draw the inner circle and outer circle with the center of each corner wheel as the center. Control the diameter of the inner circle and the outer circle to be smaller than the corresponding corner wheel. The difference between the radius of the inner circle and the outer circle of each corner wheel is d. For any two adjacent corner wheels A and B, the inner circle of corner wheel A is tangent to the outer circle of corner wheel B, and the outer circle of corner wheel A is tangent to the inner circle of corner wheel B. The diameter of the inner circle of each corner wheel is the diameter of the circular protrusion of each corner wheel.

[0053] In rotary three-dimensional braiding machines A** and B**, an auxiliary protrusion with the same shape and size as the outer circle is provided below the area not covered by all the outer circles. The upper surface of the auxiliary protrusion is flush with the upper surface of the circular protrusion, and the thickness of the auxiliary protrusion is equal to h. The auxiliary protrusion is fixedly connected to the base plate below the corner wheel through a cylinder.

[0054] Beneficial effects:

[0055] (1) The present invention is based on the linkage control mode of the grooved wheel, using a single motor to drive all the corner wheels, and can also use a clutch device on each corner wheel (i.e., through the inner shaft on the middle section of the transmission shaft, the sliding sleeve and the connection of it to the cylinder shaft through the rod) to realize power transmission control, so as to realize independent control of each corner wheel by independently controlling each clutch device.

[0056] (2) This invention achieves precise control of the movement of diagonal wheels by utilizing a transmission shaft containing a sliding sleeve. Its greatest advantage lies in simplifying the precise rotation control of a single diagonal wheel into a linear motion over a fixed distance. In this way, not only are the problems caused by the use of a large number of stepper motors avoided, but the linkage control also makes the coordination of the intermittent movements between the diagonal wheels more stable.

[0057] (3) The present invention can achieve full load of yarn carrier, which, compared with the traditional five-column braiding machine (which will cause interference when fully loaded), allows the same corner wheel to carry more yarn. Attached Figure Description

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0092] In the n Geneva mechanisms of the following embodiments, the number of pins on the dial in the i-th Geneva mechanism is r. i The number of transmission slots on the Geneva wheel in the i-th Geneva mechanism is s. i i = 1, 2, ..., n, n, r i s i The relationship satisfies the following formula:

[0093]

[0094] Example A1

[0095] Rotary three-dimensional knitting machine based on linkage control mode, such as Figure 1 , Figure 2 As shown, it includes a yarn carrier, an intermittent drive device, m horizontally arranged corner wheels 3 and m vertically arranged drive shafts 10, where m is 16.

[0096] m corner wheels 3 are fixed to the top of m drive shafts 10 respectively. All corner wheels 3 are divided into n groups, where n is 2 (e.g., ...). Figure 1 As shown, the first group of corner wheels is white, and the second group of corner wheels is blue. The areas swept by the corner wheels of the same group in a 360° rotation do not overlap and rotate synchronously. The corner wheels of different groups do not rotate synchronously.

[0097] The m drive shafts are divided into two groups of 10. One group has n shafts, denoted as drive shaft A, and the other group has (mn) shafts, denoted as drive shaft B.

[0098] The intermittent drive device includes n Geneva mechanisms and a motor 8. The Geneva mechanism can be encapsulated in a box 7 by an intermittent motion generator.

[0099] like Figure 2 As shown, each Geneva mechanism includes a horizontally arranged dial as the driving element and a horizontally arranged Geneva wheel 2 as the driven element.

[0100] The dial includes a dial plate 1, a pin 14 vertically disposed on the dial plate 1, and a positioning plate 15;

[0101] The thickness surface of the positioning plate 15 is composed of a convex arc surface and at least one concave arc surface; the positioning plate 15 is located above the lever plate 1, and the two are coaxial and fixedly connected.

[0102] The grooved wheel 2 is a rotating disk with radially evenly distributed radiating transmission grooves. The thickness of the rotating disk is composed of at least the groove walls of each transmission groove and multiple concave arc surfaces.

[0103] The convex arc surface of the positioning plate 15 can be rotated to fit against the concave arc surface of the rotating disk. At this time, the grooved wheel 2 is braked and is in an intermittent state.

[0104] When the dial rotates around its own central axis, it drives the pin 14 to engage in the transmission groove, driving the groove wheel 2 to rotate around its own central axis.

[0105] like Figure 2 , Figure 5 As shown, n Geneva mechanisms are arranged sequentially from bottom to top.
