Description

Technical Field

[0001] The utility model belongs to the field of winding devices, in particular to an automatic winding machine. Background Art

[0002] Winders are specialized equipment for the textile industry. As the final step in spinning and the first step in weaving, they serve as a bridge between the previous and next steps, and therefore play an important role in the textile field. Winders can adapt to the processing of various fibers and can perform different treatments and adjustments to meet various production needs. Traditional winders, such as grooved drum cars, cannot automatically replace the bobbin to wind the next bobbin after the bobbin has wrapped a specified amount of yarn. Instead, they rotate the already wound bobbin and the spare bobbin to swap positions, and then manually remove the wound bobbin, resulting in low efficiency and requiring a human to stay next to the machine to monitor and replace the bobbin at any time.

[0003] For example, a Chinese utility model patent discloses a winding machine that can automatically replace paper tubes [application number CN202010768438.X], comprising a storage shell and a storage cavity arranged in the storage shell, wherein paper tubes are stored in the storage cavity, and a lower opening is provided at the right end of the storage cavity, and a replacement cavity is provided in the storage shell, and the replacement cavity and the storage cavity are connected through the lower opening. Compared with the traditional grooved drum winder, the utility model adds the function of automatic replacement of paper tubes, and removes the grooved drum to directly rotate the spindle for winding. The user can set the amount of yarn to be wound on each paper tube. When the wound yarn reaches the specified amount, the device will start the automatic replacement of the paper tube, collect the paper tubes that have been wound with yarn, and then install a new paper tube for re-winding. Although this technical solution realizes automatic tube replacement, the operation of automatic tube replacement is relatively complicated. Utility Model Content

[0020] 4. The position of the left arm and the right arm can be adjusted according to the length of the wire tube. The distance between the left arm and the right arm can be adjusted by sliding the left arm and the right arm with the slide groove, and the left arm and the right arm can be fixed with bolts and nuts.

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] The utility model provides an automatic winding machine, combined with Figure 1-7 As shown, it includes a frame 10, and the upper end of the frame 10 is provided with at least one pipe storage structure 11. The outlet of the pipe storage structure 11 is connected to a pipe delivery structure 12 with a lifting function. Below the pipe storage structure 11, there is a winding and changing pipe structure 13 arranged on the frame 10 and with a winding function.

[0031] In this embodiment, the pipe storage structure 11 is used to place multiple spare wire pipes 100. During the automatic pipe changing process, the spare wire pipe falls from the outlet of the pipe storage structure 11 and moves into the pipe delivery structure 12. Then the pipe delivery structure 12 descends and moves with the spare wire pipe to the winding pipe changing structure 13, and is replaced by the winding pipe changing structure 13. After the replacement, the wire is wound up. After the pipe delivery structure 12 moves the spare wire pipe, it rises and moves back to the initial position. At this time, the pipe delivery structure 12 is connected to the outlet of the pipe storage structure 11, so that the spare wire pipe falls and moves into the pipe storage structure 11 in preparation for the next pipe changing.

[0032] The pipe storage structure 11 includes a placement rack 14 , which has a pipe storage cavity 15 therein and forms a transport surface on which spare wire pipes 100 are arranged. The outlet of the transport surface can be connected to the inlet of the pipe delivery structure 12 .

[0033] In this embodiment, the transport surface is placed in an inclined shape, and the horizontal height of the transport surface close to the pipe delivery structure 12 is lower than the horizontal height of the transport surface away from the pipe delivery structure 12. Multiple spare wire pipes are arranged on the transport surface at one time, and can automatically move toward the pipe delivery structure 12 under the inclined guidance of the transport surface, so that the spare wire pipes move under the action of their own gravity. After a pipe is replaced, the spare wire pipe will automatically move to transfer the next spare wire pipe to the pipe delivery structure 12.

[0034] The transport surface is provided with at least one anti-jumping piece 16 at its exit. The anti-jumping piece 16 is arranged on the side of the transport surface, and an inclined surface 17 is provided at one end of the anti-jumping piece 16 away from the transport surface exit.

[0035] In this embodiment, when the spare wire tube moves, it can move to the bottom of the anti-jump plate 16 and move into the pipe delivery structure 12 under the action of its own gravity. Due to the inclination of the transport surface and the downward pressure of the anti-jump plate 16, the spare wire tube can be prevented from getting stuck and jumping out of the transport surface, so that the movement and pipe replacement work of the spare wire tube can be carried out in an orderly manner.

[0036] The pipe delivery structure 12 includes a placement frame 18, a placement cavity 19 is provided in the placement frame 18, the placement frame 18 is connected to the output shaft of the lifting driver 20 provided on the frame 10, and an anti-escape structure 21 is provided in the placement cavity 19.

[0037] In this embodiment, the spare wire tube that falls from the transport surface is moved into the placement cavity 19. Since the pipe delivery structure 12 will be displaced during the transfer process, and the stopping of the pipe delivery structure 12 will cause the spare wire tube to vibrate slightly, the spare wire tube is clamped in the placement cavity 19 by the anti-escape structure 21 to prevent the spare wire tube from falling out when the pipe delivery structure 12 is in operation.

[0038] The anti-escape structure 21 includes a stop plate 22 arranged on the inner wall of the bottom of the placement cavity 19, and an upper pressing plate 23 is arranged in the placement cavity 19 above the stop plate 22. The upper pressing plate 23 is placed in an inclined shape, and the distance between the upper pressing plate 23 and the inner wall of the bottom of the placement cavity 19 gradually decreases from one end close to the transport surface to the other end.

[0039] In this embodiment, after the spare wire tube falls from the transport surface into the placement cavity 19, it will move between the upper pressing plate 23 and the bottom inner wall of the placement cavity 19, thereby stabilizing the spare wire tube.

[0040] A torsion spring support shaft 24 is fixed in the placement cavity 19 , the upper pressing plate 23 is rotatably connected to the torsion spring support shaft 24 , and a torsion spring 25 is further provided between the upper pressing plate 23 and the torsion spring support shaft 24 .

[0041] In this embodiment, the elastic force generated by the torsion spring 25 is not large. When the spare wire tube falls from the transport surface into the placement cavity 19, the upper pressing plate 23 can be pushed open. As the spare wire tube continues to fall into the placement cavity 19, the upper pressing plate 23 presses the spare wire tube downward under the elastic force generated by the torsion spring 25, thereby stabilizing the spare wire tube.

[0042] The winding and tube-changing structure 13 includes a flip shaft 26 , both ends of which are arranged on a support frame, and the support frame is fixed on the frame 10 . The power source of the flip shaft 26 is arranged in a support block 27 , and a tube-mounting structure 28 is also provided on the flip shaft 26 .

[0043] In this embodiment, during the tube changing process of the winding tube changing structure 13, the tube delivery structure 12 moves downward with the spare wire tube and moves downward to a position close to the winding tube changing structure 13. The flip shaft 26 rotates under the operation of its power source and flips the entire winding tube changing structure 13, so that the part of the winding tube changing structure 13 used to install the wire tube is close to the tube delivery structure 12, and then the spare tube is installed through the tube installation structure 28.

[0044] The pipe mounting structure 28 includes a left arm 29 and a right arm 30 arranged on the flip axis 26. The end of the right arm 30 away from the flip axis 26 is provided with a right support block 35, and the end of the left arm 29 away from the flip axis 26 is provided with a linear drive 31. The output shaft of the linear drive 31 is connected to the left support block 27, and the left support block 27 can approach or move away from the right support block 35.

[0045] In this embodiment, after the current wire tube is in the tube loading structure 28 and the wire winding is completed, the flip shaft 26 flips the entire winding and changing tube structure 13. At this time, the left support block 27 is disconnected from the wire tube by the operation of the linear drive 31, thereby removing the wire tube with the wire wound thereon. At this time, there is no wire tube in the tube loading structure 28. At this time, the tube feeding structure 12 moves downward with the spare wire tube, so that the spare wire tube is located between the left support block 27 and the right support block 35. Then the linear drive 31 works to move the left support block 27 close to the right support block 35, thereby pushing the spare wire tube and clamping the spare wire tube between the left support block 27 and the right support block 35. After the installation is completed, the flip shaft 26 rotates back to the winding station to wind the spare wire tube.

[0046] The right support block 35 is rotatably connected to the right arm 30. A rotating motor is provided in the right arm 30. A transmission belt 32 is connected to the output shaft of the rotating motor. The other end of the transmission belt 32 is connected to the right support block 35. The cross-sections of the left support block 27 and the right support block 35 are truncated cone-shaped, and the side with a smaller diameter is located on the inner side. Several racks 33 are provided on the outer surface of the right support block 35.

[0047] In this embodiment, after the tube loading structure 28 is loaded and flipped to the winding station, the rotary motor in the right arm 30 starts to work, and the transmission toothed belt 32 drives the right support block 35 to rotate, thereby driving the spare wire tube to rotate, and the wire is wound onto the spare wire tube and then the winding work is carried out. In addition, the rack 33 increases the firmness between the right support block 35 and the spare wire tube to prevent the spare wire tube from slipping.

[0048] A slide groove 34 is further provided in the flip shaft 26, and the left arm 29 and the right arm 30 are slidably connected to the slide groove 34, and the left arm 29 and the right arm 30 are movably fixed in the slide groove 34 by means of bolts and nuts.

[0049] In this embodiment, the position of the left arm 29 and the right arm 30 can be adjusted according to the length of the wire tube. The distance between the left arm 29 and the right arm 30 is adjusted by sliding the left arm 29 and the right arm 30 with the slide groove 34, and the left arm 29 and the right arm 30 are fixed by bolts and nuts.

[0050] Preferably, when the winding and tube changing structure 13 is located at the winding station, a thickness detection shaft 36 is provided under the left arm 29 and the right arm 30. When the bobbin is a winding wire, there is a gap between the bobbin and the thickness detection shaft 36. The bobbin will gradually become thicker when it is wound. When the coil and the thickness detection shaft 36 are against each other, it means that the winding is completed. At this time, the rotating motor in the right arm 30 stops working, and the steps of collecting and changing the tube are performed.

[0051] Preferably, a pipe receiving structure 37 is provided below the pipe delivery structure 12 . The pipe receiving structure 37 includes a pipe receiving frame 38 . Two baffles 39 are provided on the pipe receiving frame 38 . A pipe receiving space 40 is formed between the two baffles 39 .

[0052] In this embodiment, after the current wire tube is in the tube loading structure 28 and the winding is completed, the flip shaft 26 flips the entire tube winding and changing structure 13. At this time, the linear drive 31 operates to disconnect the left support block 27 from the wire tube, so that the wound wire tube falls into the corresponding tube receiving space 40. The baffle 39 can collect all the wire tubes in the tube receiving space 40.

[0053] Preferably, the placement frame 18 is provided with a detachable shielding plate 41, and the shielding plate 41 can close the placement frame 18. When not in use or when the spare wire tube is not needed, the shielding plate 41 is installed on the placement frame 14.

[0054] The working principle of the present invention is as follows: a plurality of spare tubes are placed on the placement surface, and under the guidance of the placement surface and the gravity of the tubes themselves, they fall and move to the placement frame 18, and the spare tubes are stabilized by the upper pressing piece 23. After the previous tube is wound, the turning shaft 26 turns over the entire winding tube-changing structure 13. At this time, the left support block 27 is disconnected from the tube by the operation of the linear drive 31, so that the wound tubes fall into the corresponding tube-collecting space 40. The baffle 39 can collect the tubes in the tube-collecting space 40. At this time, the tube-feeding structure 12 moves downward. The spare wire tube is moved downward so that it is located between the left support block 27 and the right support block 35. Then the linear drive 31 works to move the left support block 27 close to the right support block 35, thereby pushing the spare wire tube and clamping the spare wire tube between the left support block 27 and the right support block 35. After the installation is completed, the flip shaft 26 rotates to the winding station to wind the spare wire tube. Then the rotating motor in the right arm 30 works, and the right support block 35 is rotated through the transmission toothed belt 32, thereby driving the spare wire tube to rotate, and the winding work is carried out after the wire is wound around the spare wire tube.
