Description

Technical Field

[0001] This invention relates to the field of wire wrapping technology, and in particular to a wrapping machine and a winding method thereof. Background Technology

[0003] An automatic take-up machine is a machine that winds thread-like objects onto specific workpieces. Large cable reels are widely used in equipment such as wire drawing machines, stranding machines, extruders, cabling machines, and armoring machines, as well as in turnover, delivery, and annealing processes. Commonly used automatic take-up machines wind enameled copper wire (for winding inductor coils in electronic and electrical products), textile wire (for winding yarn spools and balls used in textile machines), as well as heating wire for electric heating appliances, solder wire, electrical wires, and cables.

[0004] In the cable production process, a wrapping operation is required around the core wire. Traditionally, after a roll of wrapping is finished, the machine needs to be stopped to cut the core wire before the wrapping can be replaced, and then a new wrapping reel needs to be installed. The entire replacement process is cumbersome and the downtime is long, which affects production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a wrapping machine and a wrapping method thereof to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a winding machine and its winding method, comprising a main winding disc, a winding drive module for driving the main winding disc to rotate on a fixed axis, a mounting frame for mounting the winding drive module, a rotary drive module for driving the mounting frame to rotate longitudinally, and a transverse transfer module for driving the rotary drive module to move horizontally reciprocatingly; the main winding disc and the winding drive module form a unit, and the unit has at least two units symmetrically distributed on both sides of the rotating shaft of the mounting frame; It also includes a transition winding disk coaxially fixed to one end of the main winding disk, and the end of the main winding disk near the transition winding disk is provided with a guide to guide the wire core onto the transition winding disk; The main winding disc and the shaft of the winding drive module are detachably connected.

[0007] The winding machine of the present invention includes a main winding disc comprising a winding roller coaxially sleeved on the rotating shaft of the winding drive module, and a limiting disc coaxially disposed at both ends of the winding roller; the transition winding disc is detachably connected to the winding roller.

[0008] In the wrapping machine of the present invention, the outer peripheral sidewall of the limiting disk is provided with a through groove that axially penetrates both sidewalls thereon, and the through groove forms the guide.

[0009] In the winding machine of the present invention, one end of the through groove facing its rotation axis is flush with the outer peripheral sidewall of the winding roller.

[0010] In the winding machine of the present invention, a winding groove is coaxially provided on the outer peripheral sidewall of the transition winding disc, the diameter of the transition winding disc is the same as the diameter of the winding roller, and the diameter of the winding groove is smaller than the diameter of the winding roller.

[0011] In the wrapping machine of the present invention, the through grooves are provided in multiple ways and are evenly distributed circumferentially on the limiting plate.

[0012] The winding machine of the present invention includes a transition winding reel comprising an inner sleeve coaxially and detachably sleeved on the rotating shaft of the winding drive module, and a winding reel body coaxially disposed on the outer peripheral sidewall of the inner sleeve; a winding groove is disposed on the outer peripheral sidewall of the winding reel body; both the inner sleeve and the winding reel body are detachably connected to the winding roller; and the winding reel body is provided with a cutting component for cutting the wire.

[0013] The winding machine of the present invention includes a winding roller having a channel coaxially extending through both ends therethrough. The diameter of the channel is larger than the diameter of the rotating shaft of the winding drive module. The inner sleeve has a tapered section at one end facing the winding roller, and the diameter of the channel is located between the minimum and maximum diameter of the tapered section. The winding roller is provided with a positioning component at one end away from the inner sleeve, which is coaxially and detachably connected to the rotating shaft of the winding drive module. When assembled, the positioning component and the inner sleeve coaxially fix the winding roller on the rotating shaft of the winding drive module.

[0014] Furthermore, the present invention also provides a winding method for a wrapping machine, the winding method comprising the following steps: Step S10: Introduce the wire into the main winding reel and pass it through the guide to one side of the transition winding reel; Step S20: The winding roller is gradually wound from one end near the transition winding disc to the other end and then gradually wound back to form a winding cycle. The axial movement of the winding roller in each cycle is achieved by the lateral movement module. Step S30: When the number of winding coil layers reaches a preset value, the winding roller is driven to move axially through the transverse module so that the wire passes through the guide line and enters the outer side of one end near the transition winding disc from the inside of the winding roller. Step S40: Drive the two units to swap positions using the rotary drive module, and perform a winding operation on the unwound unit. When the second unit enters the winding process, perform a material removal operation on the first unit that has been wound.

[0015] The winding method of the wrapping machine of the present invention, wherein step S40 includes: After the two units are swapped, the first unit that has completed the winding operation continues to wind the wire for a preset time period. After the preset time period is completed, the second unit that has not yet wound the wire completes the winding of the wire to a preset length. After the wire has been wound to the preset length, both ends of the wire on the transition winding reel are cut off. One cutting point is located between the wire outlet of the transition winding reel and the wire inlet of the second unit currently performing the winding operation, and the other cutting point is located between the wire outlet of the guide and the wire inlet of the transition winding reel. The winding roller and the transition winding disc are removed from the rotating shaft of the winding drive module in sequence.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The overall structure is simple. By setting at least two winding units that can be interchanged, the winding operation of the wire can be carried out without stopping the machine. When one of them is winding, the main winding disc of the other one that has been wound can be removed and a new main winding disc can be installed on the shaft of the winding drive module. This can not only significantly improve the winding efficiency, but also avoid the risk of inconsistent winding after restarting. Attached Figure Description

For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0030] Furthermore, the terms indicating orientation, such as "up," "down," "left," "right," "upper end," "lower end," and "longitudinal," are all based on the posture and position of the device or equipment described in this solution during normal use.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0032] This embodiment discloses, as follows: Figures 1 to 9 The winding machine shown includes a main winding disc 10, a winding drive module 20 that drives the main winding disc 10 to rotate on a fixed axis, a mounting frame 30 for mounting the winding drive module 20, a rotary drive module 40 that drives the mounting frame 30 to rotate longitudinally, and a transverse movement module 50 that drives the rotary drive module 40 to move horizontally reciprocally. The main winding disc 10 and the winding drive module 20 form a unit, and there are at least two units symmetrically distributed on both sides of the rotating shaft of the mounting frame 30. The winding drive module 20 and the rotary drive module 40 are both motors, specifically high-precision servo motors, or rotary cylinders. The transverse movement module 50 can be a linear motor, a lead screw motor module, or a linear module such as a motor-guide rail-slide table.

[0033] In addition, to ensure that the motor wires in each unit do not become tangled or broken during rotation, a slip ring 60 is provided on the rotating shaft of the rotary drive module 40. The electrical connection between the fixed end and the rotating end of the wire is realized through the interface of the slip ring 60. The mounting bracket 30 is fixed to the movable terminal of the transverse module 50 by a vertical stand 70, and the height can be adjusted according to actual needs.

[0034] Furthermore, this winding machine also includes a transition winding disc 80 coaxially fixed to one end of the main winding disc 10, used for winding the factory quality inspection wire for testing the coil; the end of the main winding disc 10 near the transition winding disc is provided with a guide to guide the wire core onto the transition winding disc 80; wherein, the main winding disc 10 and the shaft 201 of the winding drive module 20 are detachably connected.

[0035] Before the wire enters the main winding spool, it is guided and limited by two radially close guide wheels 90, which are fixedly installed by the external bracket of the equipment. Specifically, one of the two guide wheels 90 has an annular protrusion 91 coaxially provided on its peripheral sidewall, and the other has an annular groove 92 coaxially provided on its peripheral sidewall, which is adapted to the thickness of the annular protrusion 91. The radial depth of the annular groove 92 is greater than the radial width of the annular protrusion 91. After assembly, the space between the end face of the annular protrusion 91 and the bottom face of the annular groove 92 forms a positioning cavity and realizes the wire feeding cavity.

[0036] The overall structure of this solution is simple. By setting at least two winding units that can be interchanged, the winding operation of the wire can be carried out without stopping the machine. When one of them is winding, the main winding disc 10 of the other one that has been wound can be removed and a new main winding disc 10 can be installed on the shaft 201 of the winding drive module 20. This can not only significantly improve the winding efficiency, but also avoid the risk of inconsistent winding after restarting.

[0037] Furthermore, the angle between the line connecting the centers of the two units and the horizontal plane is 30 degrees. The two guide wheels 90 are located on the feeding side of the unit at the higher position and are higher than the rotation axis of that unit, so that the operator can perform wire guiding and material picking operations without bending over.

[0038] In this embodiment, the main winding disk 10 includes a winding roller 101 coaxially sleeved on the rotating shaft 201 of the winding drive module 20, and a limiting disk 102 coaxially disposed at both ends of the winding roller 101; the transition winding disk 80 is detachably connected to the winding roller 101, and the transition winding disk 80 and the winding roller 101 are specifically connected by an axial positioning pin (not shown in the figure), which can ensure that the two can rotate synchronously; after assembly, the transition winding disk 80 is tightly fitted with the rotating shaft 201 of the winding drive module 20 and can maintain synchronous rotation.

[0039] In this embodiment, the outer peripheral sidewall of the limiting disk 102 is provided with a through groove 120 that axially penetrates both sidewalls. The through groove 120 forms a guide. Specifically, one end of the through groove 120 facing its rotation axis is flush with the outer peripheral sidewall of the winding roller 101. The through groove 120 not only guides the wire from the winding roller 101 to the transition winding disk 80, but also locks the front end of the wire to the winding roller 101 in the early stage of winding, so that the rear part of the wire can rotate synchronously with the winding roller 101 to realize the wrapping operation.

[0040] In this embodiment, a winding groove 130 is coaxially provided on the outer peripheral sidewall of the transition winding disc 80. The diameter of the transition winding disc 80 is the same as the diameter of the winding roller 101, and the diameter of the winding groove 130 is smaller than the diameter of the winding roller 101. Specifically, the axial cross-section of the winding groove 130 is trapezoidal, and the axial width of the centripetal end is smaller than the axial width of the vest end, so that the winding groove 130 forms an open structure, so that the wire in the winding groove 130 can be easily removed during the later quality inspection of the winding package.

[0041] In this embodiment, multiple through slots 120 are provided and are evenly distributed circumferentially on the limiting disk 102 to reduce the travel of the winding roller 101 when it rotates to the starting angle of winding, which helps to improve the winding efficiency.

[0042] In this embodiment, the transition winding reel 80 includes an inner sleeve 81 coaxially and detachably sleeved on the rotating shaft 201 of the winding drive module 20, and a winding reel body 82 coaxially and integrally disposed on the outer peripheral sidewall of the inner sleeve 81. The winding reel body 82 is coaxially disposed at one end of the main winding reel near the winding drive module. The winding reel body 82 is provided with a cutting component 8a for cutting wire. The cutting component 8a specifically includes a strip groove a1 disposed on the end face of the winding reel body near the winding drive module. The strip groove a1 is arranged along the chord of the winding reel body 82 and its... Both ends of the strip groove a1 penetrate the peripheral sidewall of the winding reel body. On the inner wall of the side of the strip groove a1 facing away from the axis of the winding reel body 82, there is a notch groove a11 that penetrates the peripheral sidewall of the winding reel body. The notch groove a11 and the strip groove a1 form a fan-shaped groove area with the fan center located in the strip groove a1. Furthermore, the cutting assembly 8a also includes a cutting blade a2 provided on the side wall of the notch groove a11 facing away from the axis of the winding reel body 82. The cutting blade a2 is parallel to the axis of the winding reel body 82 and the cutting edge faces the direction of rotation of the winding reel body 82.

[0043] Furthermore, the cutting assembly 8a also includes an infeed guide wheel a13 coaxially disposed at one end of the winding reel body 82 away from the winding roller 101. The diameter of the infeed guide wheel a13 is smaller than the diameter of the winding reel body 82 and is the same distance from the axis of the winding reel body 82 as the strip groove a1. That is, the peripheral sidewall of the infeed guide wheel a13 is flush with the inner wall of the strip groove a1. The axial length of the infeed guide wheel a13 must be guaranteed to be a certain length so that the wire can enter from the infeed guide wheel of one unit to the guide wheel of another unit under the joint drive of the transverse module and the rotary drive module.

[0044] Furthermore, the winding reel body 82 has an axial extension 821 on one side of the axis opposite to the strip groove a1. The extension 821 is arranged in the direction opposite to the winding roller, and the end of the cutting blade a2 is flush with the end of the extension 821. The structural design of the extension 821 allows the wire to be guided into the strip groove a1 when the winding reel body 82 rotates and winds, and the wire to contact the cutting edge of the cutting blade during continuous rotation to achieve cutting. In order to accommodate wires of different diameters and prevent the wire from slipping out of the strip groove, the width of the strip groove a1 is gradually narrowed along the axial direction, that is, the axial cross section of the strip groove a1 is V-shaped, which avoids the wire sliding back and forth axially during cutting.

[0045] The axial length of the inner sleeve 81 is greater than the axial length of the winding reel body 82; the winding groove 130 is provided on the outer peripheral side wall of the winding reel body; the inner sleeve 81 is detachably connected to the winding roller 101, specifically, the inner sleeve 81 and the winding roller 101 are axially abutted.

[0046] The main body of the winding reel is fixed to the winding roller 101 by an axial positioning pin, wherein the positioning pin is designed to be axially installed and removed.

[0047] In this embodiment, the winding roller 101 is coaxially provided with a channel 11 that passes through both ends of it. The diameter of the channel 11 is larger than the diameter of the rotating shaft 201 of the winding drive module 20. The inner sleeve 81 is provided with a tapered section 810 at one end facing the winding roller 101. The diameter of the channel 11 is located between the minimum diameter and the maximum diameter of the tapered section 810. When assembled in place, the inner wall of the channel 11 abuts against the inclined surface of the tapered section 810. The winding roller 101 has a positioning element 140 at the end opposite to the inner sleeve 81, which is coaxially and detachably connected to the rotating shaft 201 of the winding drive module 20. Specifically, the end of the positioning element 140 facing the winding roller also has a tapered section 160, the minimum and maximum diameters of which are consistent with the minimum and maximum diameters of the tapered section 810 on the inner sleeve. The positioning element 140 is threadedly connected to the rotating shaft 201 of the winding drive module 20. When assembled, the positioning element 140 and the inner sleeve 81 coaxially fix the winding roller 101 on the rotating shaft 201 of the winding drive module 20.

[0048] This embodiment also provides a winding method for a wrapping machine, which includes the following steps: Step S10: Introduce the wire into the main winding reel 10 and pass it through the guide inside to one side of the transition winding reel 80; Step S20: The winding roller 101 gradually winds from one end near the transition winding disc 80 to the other end and then gradually winds back to form a winding cycle. The axial movement of the winding roller 101 in each cycle is achieved by the transverse module 50. Step S30: When the number of winding coil layers reaches a preset value, the winding roller 101 is driven to move axially through the transverse module 50 so that the wire passes through the guide wire and enters the outer side of one end near the transition winding disc 80 via the inner side of the winding roller 101. Step S40: Drive the two units to swap positions by rotating the drive module 40, and perform a winding operation on the unwound unit. When the second unit enters the winding process, perform a material removal operation on the first unit that has been wound.

[0049] In this embodiment, step S40 includes: After the two units are swapped, the first unit that has completed the winding operation continues to wind the wire for a preset time period. After the preset time period is completed, the second unit that has not yet wound the wire winds the wire to a preset length. After the wire has been wound to the preset length, both ends of the wire on the transition winding reel 80 are cut off. One cutting point is located between the wire outlet of the transition winding reel 80 and the wire inlet of the second unit currently performing the winding operation, and the other cutting point is located between the wire outlet of the guide and the wire inlet of the transition winding reel 80. The winding roller 101 and the transition winding disc 80 are removed from the rotating shaft 201 of the winding drive module 20 in sequence.
