Description

Technical Field

[0001] The present invention relates to the technical field of underwear production equipment, and more particularly to an automatic bra underwire threading device and a underwire threading method. Background Art

[0002] The underwire is the main supporting frame of the bra. Currently, it is mainly inserted and fixed manually. Moreover, since the underwire is usually an irregular arc-shaped underwire, that is, it is composed of multiple arc-shaped steel bars of different diameters, the operator needs to have relatively skilled skills when inserting it, and the efficiency is low. Summary of the Invention

[0003] The object of the present invention is to provide an automated bra underwire threading device and an underwire threading method, which have the advantages of facilitating underwire threading and improving threading efficiency.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] An automatic bra underwire threading device, comprising:

[0006] A frame, wherein the front end of the frame is provided with a bracket for supporting the bra;

[0007] a pressing mechanism carried by the frame and located above the bracket for pressing the bra;

[0008] A clamping mechanism rotatably mounted on the frame for clamping or releasing the steel ring to be threaded, the clamping mechanism comprising: a first clamping assembly and a second clamping assembly arranged opposite to each other, a clamping drive mechanism for driving the first clamping assembly and the second clamping assembly to move relative to each other; and

[0009] A threading drive mechanism is used to drive the clamping mechanism to rotate back and forth so as to thread the steel ring into a predetermined track in the bra in sections.

[0010] To implement the above technical solution, when inserting the underwire, the bra is first placed on the bracket and the bra is pressed and fixed at a corresponding angle by the crimping mechanism. The first clamping assembly and the second clamping assembly are then driven by the clamping drive mechanism to move relative to each other and clamp the underwire. The clamping mechanism is then driven to rotate toward the bracket by the insertion drive mechanism to insert the first section of the underwire into the bra. The clamping mechanism is then released and driven by the insertion drive mechanism to rotate in the opposite direction to the position required for inserting the second section of the underwire. Since the underwire is an irregular arc, the angle of each reciprocating rotation of the insertion drive mechanism is different. The underwire can be completely inserted into the bra by performing multiple insertion processes through the clamping mechanism and the insertion drive mechanism. After the insertion is completed, the crimping mechanism is released to take out the bra, thereby realizing an automated underwire insertion process and improving production efficiency.

[0011] As a preferred solution of the present invention, the crimping mechanism includes: a crimping cylinder fixed to the frame, a pressing plate fixed to the piston rod of the crimping cylinder, and a pressing column fixed to the pressing plate.

[0012] By implementing the above technical solution, the bra can be compressed and loosened by extending and retracting the piston rod of the compression cylinder.

[0013] As a preferred solution of the present invention, a pressing groove adapted to the pressing column is provided on the bracket, and one side of the pressing groove is used to guide the guide wheel set of the steel ring.

[0014] To implement the above technical solution, the bra can be pressed more firmly by providing the crimping groove, and the underwire can be conveniently guided by the guide wheel group. The combination of the two makes it more convenient to insert the underwire into the bra.

[0015] As a preferred solution of the present invention, the first clamping assembly includes: a first mounting plate, a first clamping plate slidably assembled on the first mounting plate, and a first elastic reset assembly carried on the first mounting plate for always keeping the first clamping plate with a tendency to remain in the middle position, and the first mounting plate is fixed to the driving part of the penetration driving mechanism.

[0016] As a preferred solution of the present invention, the second clamping assembly includes: a second mounting plate, a second clamping plate slidably assembled on the second mounting plate, and a second elastic reset assembly carried on the second mounting plate for always keeping the second clamping plate with a tendency to remain in the middle position. The clamping drive mechanism is a driving cylinder, which is fixed to the first mounting plate, and the piston rod of the driving cylinder passes through the first mounting plate and is fixed to the second mounting plate.

[0017] As a preferred solution of the present invention, the first elastic reset assembly includes a first spring and a second spring of identical size and symmetrically arranged, a first connecting block and a second connecting block are provided in the middle position of one side of the first splint, one end of the first spring is connected to the first connecting block, and one end of the second spring is connected to the second connecting block; the second elastic reset assembly includes a third spring and a fourth spring of identical size and symmetrically arranged, a third connecting block and a fourth connecting block are provided in the middle position of one side of the second splint, one end of the third spring is connected to the third connecting block, and one end of the fourth spring is connected to the fourth connecting block.

[0018] To implement the above technical solution, the first clamping assembly and the second clamping assembly can be driven to move relative to each other by driving the telescopic action of the cylinder piston cylinder, and the steel ring is clamped by the first clamping plate and the second clamping plate. Since the steel ring is an irregular arc, the first clamping plate and the second clamping plate will undergo a certain displacement during the process of threading the steel ring. When the clamping mechanism is released, under the action of the first spring, the second spring, the third spring and the fourth spring, the first clamping plate and the second clamping plate can be driven to move to the middle position of the first mounting plate and the second mounting plate respectively, to facilitate the next threading action.

[0019] As a preferred solution of the present invention, a first adjusting member and a second adjusting member are threadedly connected on both sides of the first clamping plate on the first mounting plate, the other end of the first spring is fixed to the first adjusting member, and the other end of the second spring is fixed to the second adjusting member; a third adjusting member and a third adjusting member are threadedly connected on both sides of the second clamping plate on the second mounting plate, the other end of the third spring is fixed to the third adjusting member, and the other end of the fourth spring is fixed to the fourth adjusting member.

[0020] To implement the above technical solution, the tensioning forces of the first spring, the second spring, the third spring and the fourth spring can be adjusted respectively by the first adjusting member, the second adjusting member, the third adjusting member and the fourth adjusting member.

[0021] As a preferred solution of the present invention, an auxiliary supporting plate is provided on the frame at a side of the clamping mechanism away from the bracket, and auxiliary guide wheels are provided on the auxiliary supporting plate.

[0022] The implementation of the above technical solution can provide auxiliary support and guidance to the steel ring, further facilitating the threading action.

[0023] As a preferred solution of the present invention, the threading drive mechanism includes a servo motor, the frame is provided with a control system, the control system includes a display touch screen, the crimping cylinder, the clamping drive mechanism and the threading drive mechanism are all connected to the control system.

[0024] On the other hand, the invention further provides a bra underwire threading process, the process being based on the underwire threading device described in claim 9, comprising:

[0025] Step 1: setting a corresponding control program according to the shape and size of the steel ring to be threaded and importing and storing it in the control system;

[0026] Step 2: The control system controls the pressing mechanism to press and fix the bra;

[0027] Step 3: Using the clamping drive mechanism, drive the first clamping assembly and the second clamping assembly to clamp the steel ring relative to each other to fix it;

[0028] Step 4: Controlling the insertion drive mechanism to rotate the clamping mechanism according to the control program to insert the first section of the underwire into the bra, then again driving the first clamping assembly and the second clamping assembly by the clamping drive mechanism to release the underwire, and again controlling the insertion drive mechanism to rotate the clamping mechanism in the opposite direction to a clamping position for inserting the second section of the underwire according to the control program;

[0029] Step 5: Repeat steps 3 and 4 until all the underwires are inserted into the bra.

[0030] In summary, the present invention has the following beneficial effects:

[0031] The embodiment of the present invention provides an automated bra underwire threading device and a method, wherein the device includes: a frame, a bracket for supporting the bra is provided at the front end of the frame; a pressing mechanism carried by the frame and located above the bracket for pressing the bra; a clamping mechanism rotatably assembled on the frame for clamping or releasing the underwire to be threaded, the clamping mechanism including: a first clamping assembly and a second clamping assembly arranged opposite to each other, a clamping drive mechanism for driving the first clamping assembly and the second clamping assembly to move relative to each other; and a threading drive mechanism for driving the clamping mechanism to rotate back and forth so as to thread the underwire in sections into a predetermined track in the bra. When threading the underwire, the bra is first placed on the bracket and the bra is pressed and fixed at a corresponding angle by the pressing mechanism. The first clamping assembly and the second clamping assembly are then driven by the clamping drive mechanism to move relative to each other and clamp the underwire. The clamping mechanism is then driven to rotate toward the bracket by the threading drive mechanism to thread the first section of the underwire into the bra. The clamping mechanism is then released and driven by the threading drive mechanism to rotate in the opposite direction to the position required for threading the second section of the underwire. Since the underwire is an irregular arc, the angle of each reciprocating rotation of the threading drive mechanism is different. The threading process is performed multiple times by the clamping mechanism and the threading drive mechanism, and the underwire can be finally completely threaded into the bra. After the threading is completed, the pressing mechanism is released to take out the bra, thereby realizing an automated underwire threading process and improving production efficiency.

In other embodiments, the first mounting plate 311 and the servo motor can also be transmitted through a gear transmission mechanism, a belt transmission mechanism, a chain transmission mechanism, etc.; the upper surface of the first clamping plate 312 is provided with a rubber wear-resistant layer, which can improve the wear resistance and the friction between the first clamping plate 312 and the steel ring, thereby reducing the slippage of the steel ring during the threading process, and the upper surface of the first rubber wear-resistant layer is flush with the upper surface of the bracket 11, thereby making the movement process of the steel ring more stable.

[0044] A linear guide rail 34 is provided on the first mounting plate 311 , and a slider 35 adapted to the linear guide rail 34 is provided on the first clamping plate 312 . The reciprocating sliding of the first clamping plate 312 is achieved through the cooperation between the linear guide rail 34 and the slider 35 .

[0045] The first elastic reset assembly 313 includes a first spring 3131 and a second spring 3132 of the same size and symmetrically arranged. A first connecting block 3121 and a second connecting block 3122 are provided in the middle position of one side of the first clamping plate 312. One end of the first spring 3131 is connected to the first connecting block 3121, and one end of the second spring 3132 is connected to the second connecting block 3122. The first mounting plate 311 is threadedly connected to a first adjusting member 3111 and a second adjusting member on both sides of the first clamping plate 312.

[0046] The second clamping assembly 32 includes: a second mounting plate 321, a second clamping plate 322 slidably assembled on the second mounting plate 321, and a second elastic reset assembly carried by the second mounting plate 321 for always keeping the second clamping plate 322 with a tendency to remain in the middle position. The clamping drive mechanism 33 is a driving cylinder, which is fixed to the first mounting plate 311, and the piston rod of the driving cylinder passes through the first mounting plate 311 and is fixed to the second mounting plate 321; the lower surface of the second clamping plate 322 is provided with a rubber wear-resistant layer, and the second rubber wear-resistant layer can improve the wear resistance and the friction between the steel ring and the steel ring, thereby reducing the slipping phenomenon of the steel ring during the threading process.

[0047] Correspondingly, a linear guide rail 34 is also provided on the second mounting plate 321 , and a slider 35 adapted to the linear guide rail 34 is provided on the second clamping plate 322 . The reciprocating sliding of the second clamping plate 322 is achieved through the cooperation between the linear guide rail 34 and the slider 35 .

[0048] The second elastic reset assembly includes a third spring and a fourth spring of the same size and symmetrically arranged. A third connecting block and a fourth connecting block are provided in the middle position of one side of the second clamping plate 322. One end of the third spring is connected to the third connecting block, and one end of the fourth spring is connected to the fourth connecting block.

The other end of the third spring is fixed to the third adjusting member, and the other end of the fourth spring is fixed to the fourth adjusting member.

[0049] By driving the telescopic action of the cylinder piston cylinder, the first clamping assembly 31 and the second clamping assembly 32 can be driven to move relative to each other, and the steel ring can be clamped by the first clamping plate 312 and the second clamping plate 322. Since the steel ring is an irregular arc, the first clamping plate 312 and the second clamping plate 322 will undergo a certain displacement during the threading of the steel ring. When the clamping mechanism 3 is released, under the action of the first spring 3131, the second spring 3132, the third spring and the fourth spring, the first clamping plate 312 and the second clamping plate 322 can be driven to move to the middle position of the first mounting plate 311 and the second mounting plate 321 respectively, facilitating the next threading action, and the tensioning force of the first spring 3131, the second spring 3132, the third spring and the fourth spring can be adjusted respectively by the first adjusting member 3111, the second adjusting member, the third adjusting member and the fourth adjusting member.

[0050] A control system is provided on the frame 1, and the control system includes a display touch screen 6. The control system can specifically adopt a commonly used machine tool control system, which is usually a PLC control system. The specific structure of the system is an existing structure, which will not be described here. The crimping cylinder 21, the clamping drive mechanism 33 and the threading drive mechanism 4 are all connected to the control system.

[0051] Furthermore, an auxiliary supporting plate 5 is provided on the frame 1 on the side of the clamping mechanism 3 away from the bracket 11, and an auxiliary guiding wheel 51 is provided on the auxiliary supporting plate 5, so as to provide auxiliary support and guide the steel ring left and right, further facilitating the threading action.

[0052] When threading the underwire, first place the bra on the bracket 11 and press the bra to the corresponding angle through the crimping mechanism 2, then drive the first clamping assembly 31 and the second clamping assembly 32 to move relative to each other through the clamping drive mechanism 33 and clamp the underwire, then drive the clamping mechanism 3 to rotate toward the bracket 11 through the threading drive mechanism 4 to thread the first section of the underwire into the bra, then release the clamping mechanism 3 and drive the clamping mechanism 3 to rotate in the opposite direction through the threading drive mechanism 4 to the position required for threading the second section of the underwire. Since the underwire is an irregular arc, the angle of reciprocating rotation of the threading drive mechanism 4 is different each time. By performing multiple threading processes through the clamping mechanism 3 and the threading drive mechanism 4, the underwire can be finally completely threaded into the bra. After the threading is completed, release the crimping mechanism 2 to take out the bra, thereby realizing an automated underwire threading process and improving production efficiency.

[0053] Example 2

[0054] A bra underwire threading process, the process of this embodiment is based on the underwire threading equipment described in embodiment 1, and includes:

[0055] Step 1: Set the corresponding control program according to the shape and size of the steel ring to be connected and import and store it in the control system. Several control programs can be stored in the control system. The corresponding control program can be selected through the display touch screen 6 according to the size and shape of the steel ring to be connected, making the control process more convenient and quick.

[0056] Step 2: The control system controls the crimping mechanism 2 to press and fix the bra, that is, controls the piston rod of the crimping cylinder 21 to extend, and presses and fixes the bra through the pressure column 23.

[0057] Step 3: Use the clamping drive mechanism 33 to drive the first clamping assembly 31 and the second clamping assembly 32 to clamp the steel ring relative to each other, that is, control the piston rod of the driving cylinder to retract, and clamp the steel ring through the first clamping block and the second clamping block.

[0058] Step 4: According to the control program, the threading drive mechanism 4 is controlled to drive the clamping mechanism 3 to rotate so as to insert the first section of the steel ring into the bra, and then the first clamping component 31 and the second clamping component 32 are driven by the clamping drive mechanism 33 to loosen the steel ring, and the threading drive mechanism 4 is controlled again according to the control program to drive the clamping mechanism 3 to rotate in the opposite direction to the clamping position for threading the second section of the steel ring; since the steel ring is a curved shape, not a standard arc shape, in the process of the clamping steel ring being transported forward for threading, in order to ensure smooth transportation of the steel ring, continuous radius compensation is required, that is, the first clamping plate 312 and the second clamping plate 322 will connect the clamped steel ring to move linearly inward or outward of the ring, and when the first clamping plate 312 and the second clamping plate 322 release the steel ring, they can return to the middle position under the action of the first elastic reset component and the second elastic reset component.

[0059] Step 5: Repeat steps 3 and 4 until all the steel rings are inserted into the bra, then control the piston rod of the crimping cylinder 21 to retract, loosen the bra, and then the bra can be processed and taken out.

[0060] Through the above processing steps, the steel ring threading process is automated and the production efficiency is improved.
