Detailed implementation mode

[0039] To make the above features and advantages of the present invention more understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings, but the present invention is not limited thereto.

[0040] Refer to Figures 1 to 13

[0041] A chain winding automatic winding device includes a frame 10. A tensioning mechanism 500 for tensioning the input chain is provided on the frame. A chain arranging mechanism 200 for adjusting the longitudinal position of the chain is provided at the rear of the tensioning mechanism. A chain winding mechanism 100 for mounting a winding drum and realizing chain winding is provided at the rear of the chain arranging mechanism. A paper feeding mechanism 300 for feeding spacer paper to the chain winding mechanism is provided below the chain arranging mechanism. A spacer paper pressing mechanism 400 for winding the spacer paper around the winding drum and pressing it is also provided on the frame. Thus, the separation between the inner and outer layers of the chain is realized through the spacer paper.

[0042] In this embodiment, in order to achieve the tensioning of the input chain and facilitate subsequent winding, the tensioning mechanism includes a fixing plate 510 connected to the frame. A support roller 520 is longitudinally installed at the front of the fixing plate. Limit rings 521 are installed at both ends of the support roller. An anti-drop roller 530 capable of lifting is arranged above the support roller, and a chain passing space is formed between the support roller and the anti-drop roller. A reversing roller 540 capable of elastically lifting is longitudinally installed at the rear of the support roller; one ends of the reversing roller and the anti-drop roller are both connected to the fixing plate through a guide rail slider module 550, and a tension spring 541 with its lower end connected to the lower part of the fixing plate is connected to the guide rail slider module of the reversing roller, so as to achieve the elastic lifting of the reversing roller.

[0043] In this embodiment, in order to better adjust the longitudinal position of the chain during the winding process of the chain, make the chain wind evenly on the winding drum, and avoid the chain only winding in one area, the chain arranging mechanism includes a linear module 201 arranged longitudinally. A support frame 202 is installed on the sliding table of the linear module. A chain guide groove 203 is horizontally installed at the upper end of the support frame. A chain outlet groove plate 204 is installed at the rear end of the chain guide groove. The angle of the chain outlet groove plate is adjustable, and a guide wheel 205 is installed at the end of the chain outlet groove plate. Thus, the conveying direction of the chain is defined by the chain guide groove, and the longitudinal position of the chain is adjusted during the conveying process through the linear module.

[0044] In this embodiment, in order to better adjust the output direction of the chain, the front end of the chain outlet groove plate is hinged to the chain guide groove through a connecting plate 208. An adjusting plate 209 capable of rotating and adjusting is installed at the rear end of the chain guide groove, and is locked by bolts after rotation adjustment. A spring 210 is connected to the upper end of the adjusting plate, and the other end of the spring is connected to the chain outlet groove plate, so that the chain outlet groove plate can have the ability of elastic rotation and better keep the chain under tension.

[0045] In this embodiment, since the chain is placed on the ground and will be contaminated with dust, etc., in order to collect the dust, etc. that drops during the conveying process of the chain in the chain guide groove, powder receiving grooves 206 are installed below the front ends of the chain guide grooves, and powder receiving grooves 207 are installed below the rear ends. Suction pipes are installed on the bottom plates of the powder receiving grooves. Thus, the powder receiving grooves receive the dust that drops from the chain and suck it away through the suction pipes.

[0046] In this embodiment, the chain winding mechanism includes a mounting bracket 101 fixed on the frame. A winding drum mounting shaft 104 rotatably connected to the mounting bracket and driven to rotate by a servo motor 102 is provided on the mounting bracket. A fixing disk 103 is sleeved on the mounting shaft. A number of fixing clamps 110 for the winding drum are spaced and installed on the circumferential part of the fixing disk, so that the winding drum can be sleeved on the mounting shaft and fixed by the fixing clamps. Specifically, during installation, the mounting shaft passes through the center of the fixing disk and is fixedly connected to the fixing disk. The other end of the mounting shaft is connected to the output end of the servo motor through a coupling, and the mounting shaft is rotatably installed at the upper end of the mounting bracket.

[0047] In this embodiment, in order to better install the winding drum, the fixing clamp is L-shaped. A pair of long slot holes 111 are provided on one side plate of the fixing clamp. A locking bolt 112 radially screwed to the circumferential surface of the fixing disk is inserted through the long slot holes, and the end of the winding drum is locked and clamped by the fixing clamp.

[0048] In this embodiment, in order to output the separator paper and feed it into the chain winding mechanism, the paper feeding mechanism includes a separator paper output bin 310. A guiding channel 311 with an output port facing the chain winding mechanism is provided in the separator paper output bin. A clamping and feeding mechanism 320 cooperating with the guiding channel and a cutting mechanism 330 for cutting the separator paper are provided in the separator paper output bin. A guiding plate 313 is also installed at the output port of the guiding channel. The clamping and feeding mechanism cooperates with the auxiliary conveying roller to send the separator paper out through the guiding channel, guides it to the chain winding mechanism through the guiding plate, and the cutting mechanism cuts the separator paper.

[0049] In this embodiment, the clamping and feeding mechanism includes a passive clamping roller 321 longitudinally arranged and located below the guiding channel. A rotating clamping roller 322 driven by a servo motor 323 is provided on the front side of the passive clamping roller. An auxiliary conveying roller is also installed above the guiding channel. One end of the rotating clamping roller can drive the auxiliary conveying roller to rotate synchronously through a chain or a gear pair, so as to better complete the conveying of the separator paper.

[0050] In this embodiment, in order to cut the separator paper, the cutting mechanism includes a guiding slot 331 horizontally passing through the channel. A cutting knife 332 is arranged in the guiding slot. A cutting cylinder 333 for driving the cutting knife is installed in the separator paper output bin. Thus, the cutting cylinder drives the cutting knife to complete the cutting work of the separator paper.

[0051] In this embodiment, in order to convey the spacer paper to the paper feeding mechanism, a paper winding mechanism 600 for conveying the spacer paper to the paper feeding mechanism is further provided at the lower part of the machine frame. The paper winding mechanism includes a vertical plate 610 vertically installed at the lower part of the machine frame, and two upper and lower paper tube mounting shafts 611 are longitudinally installed in the vertical plate for mounting the spacer paper reels. A spacer paper limiting shaft 620 is arranged on the front side of the paper tube mounting shaft, and limiting rings 621 are arranged at both ends of the spacer paper limiting shaft to prevent the spacer paper from shifting. A tension shaft rod 630, a reversing shaft rod 640 and an infrared sensor 650 are also arranged on the front side of the spacer paper limiting shaft to detect whether the spacer paper passes through by the infrared sensor.

[0052] In this embodiment, in order to enable the output spacer paper to be wound around the winding reel, the spacer paper pressing mechanism includes a pair of pressing paper chains 410 with one end hinged to the spacer paper output bin of the paper feeding mechanism. A plurality of rollers 411 are rotatably arranged along the length direction between the pair of pressing paper chains. The rollers can be made of plastic, such as nylon. The other ends of the pair of pressing paper chains are hinged with a connecting frame 420. A driving mechanism 430 is horizontally arranged above the chain winding mechanism and is hinged with the connecting frame to drive the connecting frame to move forward so that the pressing paper chains are wrapped around the outer side of the winding reel. A spacer paper anti - detachment mechanism 440 is also arranged between the paper feeding mechanism and the chain winding mechanism and can move towards the winding reel direction to press the spacer paper. Thus, the driving mechanism drives the other end of the pressing paper chain to move forward, so that the pressing paper chain is wrapped around the surface of the winding reel, and one end of the spacer paper can be clamped between the pressing paper chain and the winding reel. During the rotation of the winding reel, the spacer paper is wound on the surface of the inner - ring chain of the winding reel, and at the same time, the continuously input chain is wound on the outer side of the spacer paper during the rotation of the winding reel to form an outer - ring chain.

[0053] In this embodiment, in order to drive the other end of the pressing paper chain to move forward and cover the outer periphery of the winding reel, the driving mechanism includes a horizontally arranged mounting plate 431. A slider 432 that is slidably matched with the mounting plate is arranged on the lower side of the mounting plate. A winding cylinder 433 for driving the slider is horizontally installed at the front end of the mounting plate. The telescopic rod of the winding cylinder is connected with the slider to drive the slider to move forward. The upper end of the connecting frame is hinged with the slider and is provided with a rotation limiting structure, and the rotation of the mounting frame is limited through the rotation limiting structure. A vertical plate 423 is also fixed on the slider, and a return spring 424 is installed on the vertical plate. The other end of the return spring is connected with the rear part of the connecting frame, so as to facilitate the rotational reset of the connecting frame. The connecting frame is in a drooping state in the natural state.

[0054] In this embodiment, the rotation limiting structure includes an arc - shaped limiting groove 421 arranged at the upper end of the connecting frame, and a limiting pin 422 fixed on the slider and passing through the arc - shaped limiting groove, so that the rotation of the connecting frame is limited during the movement.

[0055] In this embodiment, since the paper pressing chain can only cover half of the circumference (or more than the circumference) of the winding drum and cannot wrap around the entire outer circumference of the winding drum, in order to prevent the spacer paper from detaching from the winding drum during the wrapping process, the spacer paper anti-detachment mechanism includes a sliding seat 441 that is horizontally slidably matched with the machine frame. A pair of arc-shaped pressing pieces 442 whose lower ends are rotatably connected to the sliding seat are arranged on the sliding seat. A tension spring 443 is obliquely installed at the bottom of the arc-shaped pressing piece, and the lower end of the tension spring is connected to the sliding seat, so that the arc-shaped pressing piece can have an elastic force. A pressing cylinder 444 that drives the sliding seat to make the arc-shaped pressing piece approach the winding drum is horizontally installed on the machine frame. Thus, when the winding cylinder operates, the pressing cylinder operates simultaneously to better complete the pressing work of the spacer paper. When the winding cylinder and the pressing cylinder operate, the winding chain mechanism pauses rotation and continues to rotate after the winding cylinder and the pressing cylinder end. When the spacer paper is wound around the winding drum for at least one circle, the winding cylinder and the pressing cylinder return to their original positions. The length of a single cut spacer paper is greater than the circumference of the winding drum.

[0056] In this embodiment, in order to ensure the shape and strength of the arc-shaped pressing piece, a reinforcing rib plate 445 is arranged on the upper part of the arc-shaped pressing piece. Since the part of the spacer paper that is first wound by the chain is closer to the winding cylinder, and the area that is then wound by the chain is more outwardly unfolded, in order to better fit the spacer paper, a pair of arc-shaped pressing pieces are arranged longitudinally in a staggered manner instead of side by side longitudinally.

[0057] In this embodiment, an industrial control computer and a human-machine interface are also arranged on the machine frame, which is convenient for realizing the real-time setting of winding parameters and controlling the operation of the equipment. At the same time, the problem of missing winding turns is eliminated.

[0058] Working principle: The chain is fed in through the tensioning mechanism and then sent to the winding drum of the chain winding mechanism through the chain arranging mechanism for winding. The adjustment of the winding position of the chain is achieved through the chain arranging mechanism. When the chain is about to wind one layer in the longitudinal direction on the winding drum, the paper feeding mechanism of the paper winding mechanism gradually sends out the spacer paper. After the chain winds one layer, the winding drum stops rotating. At this time, the pressing chain and the arc-shaped pressing piece of the spacer paper pressing mechanism act and cover the outside of the winding drum. Then the winding drum rotates, and the spacer paper continues to be transported. Under the action of the pressing chain and the winding drum, the rear end of the spacer paper is clamped between the pressing chain and the winding drum. During the transportation of the spacer paper, according to the preset length, the spacer paper is cut off by the cutting mechanism. The continuous rotation of the winding drum, through the cooperation of the arc-shaped pressing piece, makes the spacer paper wind around the outside of the chain already wound on the winding drum (at least one turn), and the continuously input chain presses on the outer circumference of the spacer paper. After that, the winding drum continues to rotate. When the chain winds around the spacer paper for about 3 - 5 turns, the pressing chain and the arc-shaped pressing piece reset. When the pressing chain and the arc-shaped pressing piece reset, the winding drum stops rotating. After the reset is completed, the winding drum continues to rotate, so that the chain winds axially on the outside of the spacer paper on the winding drum. Generally, the chain needs to wind 2 - 4 layers on the winding drum until the entire chain winding is completed. Finally, the winding drum is removed.

[0059] A working method for a chain winding automatic winding device is as follows:

[0060] (1) The winding drum is installed and fixed on the chain winding mechanism, and the spacer paper is pre-installed so that the spacer paper is sent into the paper feeding mechanism;

[0061] (2) One end of the chain to be wound is successively connected to the winding drum on the chain winding mechanism through the tensioning mechanism and the chain arranging mechanism;

[0062] (3) Start the device, drive the chain to wind on the winding drum through the rotation of the chain winding mechanism, and realize the adjustment of the chain winding position through the chain arranging mechanism;

[0063] (4) When the chain is about to wind one layer in the longitudinal direction on the winding drum, the paper feeding mechanism gradually sends out the spacer paper, and the winding drum stops rotating after the chain winds one layer; the pressing chain and the spacer paper anti-detachment mechanism act and cover the outside of the winding drum; the winding drum continues to rotate, the spacer paper continues to be transported, the rear end of the spacer paper is clamped between the pressing chain and the winding drum, and the spacer paper is cut off according to the preset length; the winding drum rotates continuously, and the spacer paper is wound around the outside of the chain already wound on the winding drum for at least one turn under the clamping and feeding of the pressing chain and the winding drum, and the continuously input chain presses on the outer circumference of the spacer paper;

[0064] (5) Continuously rotate around the winding drum. After the chain winds around the spacer paper for 3 - 5 turns, the paper pressing chain and the anti - detachment mechanism for the spacer paper are reset; continue to rotate the winding drum to wind the chain axially on the outer side of the spacer paper of the winding drum.

[0065] (6) Repeat steps (4) and (5) until the entire chain winding is completed.

[0066] (7) Stop the machine and remove the winding drum with the wound chain from the chain winding mechanism.

[0067] The above - mentioned is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the teachings of the present invention, designing different forms of automatic winding equipment for winding chains does not require creative labor. Without departing from the principle and spirit of the present invention, all equal changes, modifications, substitutions, and variations made within the scope of the patent application of the present invention shall fall within the scope covered by the present invention.

A working method applied to the winding chain automatic winding device described in claim 1, characterized in that, The steps are as follows: (1) The winding drum is installed and fixed on the chain winding mechanism, and the separator paper is pre-installed so that the separator paper is fed into the paper feeding mechanism; (2) One end of the chain to be wound is sequentially connected to the winding drum on the chain winding mechanism after passing through the tensioning mechanism and the chain arranging mechanism; (3) Start the equipment, drive the chain to wind around the winding drum through the rotation of the chain winding mechanism, and adjust the winding position of the chain through the chain arranging mechanism; (4) When the chain is about to wind one layer longitudinally on the winding drum, the paper feeding mechanism gradually sends out the separator paper, and the winding drum stops rotating after one layer of the chain is wound; the paper pressing chain and the separator paper anti-detachment mechanism act and cover the outside of the winding drum; the winding drum continues to rotate, the separator paper continues to be conveyed, the rear end of the separator paper is clamped between the paper pressing chain and the winding drum, and the separator paper is cut off according to the preset length; the winding drum continues to rotate, and the separator paper is clamped and fed by the paper pressing chain and the winding drum to wind at least one circle outside the chain already wound on the winding drum, and the continuously input chain presses on the outer circumference of the separator paper; (5) The winding drum continues to rotate. After the chain winds 3-5 circles on the separator paper, the paper pressing chain and the separator paper anti-detachment mechanism are reset; the winding drum continues to rotate to wind the chain axially outside the separator paper of the winding drum; (6) Repeat steps (4) and (5) until the whole chain is wound; (7) Stop the machine and remove the winding drum with the wound chain from the chain winding mechanism.
