[0002] During the production process, rolled materials are typically wound onto a core after forming and then stored in rolls. During winding, the core is usually fitted onto an air shaft, and the winding equipment drives the air shaft to rotate, which in turn rotates the core, automatically winding the material onto the core. After winding is complete, the air shaft is removed and inserted into the next empty core, and the winding equipment then drives the air shaft to rotate again, winding the material onto the empty core.

[0032] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0033] like Figure 1 As shown, this embodiment provides an automatic device for changing air shafts and cores. It includes an air shaft extraction and release device 10 and a core buffer hopper 20. The air shaft extraction and release device 10 is used to extract the air shaft from the core 8 that has been wound up and put it into the core 8 to be wound up. The core buffer hopper 20 is used to store and output the cores 8 to be wound up one by one.

[0034] like Figures 2-6 As shown, the air shaft extraction and release device 10 of this embodiment includes a frame 1, a displacement mechanism and an air shaft picking and delivering mechanism. The displacement mechanism is mounted on the frame 1 and is used to drive the air shaft picking and delivering mechanism to move up, down and left and right. The air shaft picking and delivering mechanism is used to extract and insert the air shaft from the core 8.

[0035] The displacement mechanism includes a base 2, a vertical moving mechanism 3, and a horizontal moving mechanism 4, while the air shaft delivery mechanism includes a telescopic mechanism 5 and an air shaft bearing profile 6.

[0036] The vertical moving mechanism 3 is used to drive the base 2 to move up and down on the frame 1. The horizontal moving mechanism 4 is used to drive the air bearing carrier 6 and the telescopic mechanism 5 to move left and right on the base 2. The telescopic mechanism 5 is used to drive the air bearing carrier 6 to extend and retract.

[0037] The air bearing carrier profile 6 has an extraction / release power mechanism 61 at its end. Several driven rollers 62 are mounted on the air bearing carrier profile 6, and a pressing mechanism 63 is also mounted on it. The pressing mechanism 63 presses the air shaft 7 onto the extraction / release power mechanism 61, which in turn drives the air shaft 7 to move. The driven rollers 62 support the air shaft 7. The air bearing carrier profile 6 also has an inflation / deflation mechanism 64, which inflates and deflates the air shaft 7 during extraction / release.

[0038] The vertical moving mechanism 3 and the horizontal moving mechanism 4 drive the air shaft picking and feeding mechanism to move up, down, left, and right, allowing the air shaft picking and feeding mechanism to move back and forth between the wound core 8 and the core 8 to be wound. The pressing mechanism 63 and the extraction and release power mechanism 61 on the air shaft carrier profile 6 clamp the air shaft 7 together, and then the extraction and release power mechanism 61 can extract and place the air shaft 7 by rotating forward and reverse.

[0039] When it is necessary to remove the air shaft 7, such as Figure 1 As shown, the horizontal moving mechanism 4 moves the air bearing carrier profile 6 to the side below the coil material 9, and the vertical moving mechanism 3 raises the air bearing carrier profile 6 to the air shaft 7 of the coil material 9. The telescopic mechanism 5 extends the air bearing carrier profile 6, positioning the extraction and release power mechanism 61 below the end of the air shaft 7. Then, the pressing mechanism 63 presses down, pressing the end of the air shaft 7 tightly onto the extraction and release power mechanism 61. At this time, the inflation and deflation mechanism 64 first deflates the air shaft 7, allowing the air shaft 7 to loosen the core 8. After deflation, the inflation and deflation mechanism 64 returns to its original position. Next, the extraction and release power mechanism 61 rotates forward, drawing the air shaft 7 onto the driven roller 62 of the air bearing carrier profile 6. After the shaft is drawn, the telescopic mechanism 5 retracts the air bearing carrier profile 6, and finally, the vertical moving mechanism 3 descends.

[0040] When it is necessary to place the air shaft 7, such as Figure 1As shown, the horizontal moving mechanism 4 moves the air bearing carrier profile 6 to the side below the core 8 to be wound, and the vertical moving mechanism 3 raises the air bearing carrier profile 6 so that the air shaft 7 on the air bearing carrier profile 6 is at the same height as the core 8 to be wound. Then, the telescopic mechanism 5 extends the air bearing carrier profile 6 so that the end of the air shaft 7 enters the core 8 to be wound. Then, the extraction and release power mechanism 61 reverses, which feeds the air shaft 7 into the core 8 to be wound. When the air shaft 7 is completely inserted into the core 8 to be wound, the inflation and deflation mechanism 64 inflates the air shaft 7, firmly fixing the air shaft 7 inside the core 8 to be wound. After inflation, the inflation and deflation mechanism 64 returns to its original position. Finally, the pressing mechanism 63 releases the air shaft 7, the telescopic mechanism 5 retracts the air bearing carrier profile 6, and the vertical moving mechanism 3 descends.

[0041] like Figure 2 , 3 As shown, in this embodiment, a set of vertical moving mechanisms 3 are respectively provided on the two side walls of the base 2. The two sets of vertical moving mechanisms 3 drive the base 2 to move up and down. The vertical moving mechanism 3 includes a vertical motor 31, a vertical drive wheel 32, a vertical belt 33, and a vertical driven wheel 34. The vertical motor 31 is fixed on the frame 1, the vertical drive wheel 32 is fixed on the motor shaft of the vertical motor 31, and the vertical driven wheel 34 is fixed on the frame 1. The vertical drive wheel 32 is connected to the vertical driven wheel 34 through the vertical belt 33. The side wall of the base 2 is connected to the vertical belt 33, and the side wall of the base 2 is slidably connected to the frame 1 through a slider and a slide rail. The vertical motor 31 drives the vertical drive wheel 32 to rotate, and the vertical drive wheel 32 drives the vertical belt 33 and the vertical driven wheel 34 to rotate. The vertical belt 33 can then drive the base 2 to move up and down, thereby driving the air-bearing profile 6, the telescopic mechanism 5, the pressing mechanism 63, the extraction and release power mechanism 61, and the inflation and deflation mechanism 64 on the base 2 to move up and down as a whole.

[0042] like Figure 4 As shown, the horizontal moving mechanism 4 in this embodiment includes a horizontal motor 41, a horizontal driving wheel 42, a horizontal belt 43, and a horizontal driven wheel 44. The horizontal motor 41 is fixed on the base 2, the horizontal driving wheel 42 is fixed on the motor shaft of the horizontal motor 41, and the horizontal driven wheel 44 is fixed on the base 2. The horizontal driving wheel 42 is connected to the horizontal driven wheel 44 via the horizontal belt 43. The air bearing carrier 6 is connected to the horizontal belt 43. The air bearing carrier 6 and the telescopic mechanism 5 share a base plate 9, which is slidably connected to the base 2 via a slider and a slide rail. The horizontal motor 41 drives the horizontal driving wheel 42 to rotate, which in turn drives the horizontal belt 43 and the horizontal driven wheel 44 to rotate. The horizontal belt 43 then drives the air bearing carrier 6, the telescopic mechanism 5, the pressing mechanism 63, the extraction and release power mechanism 61, and the inflation and deflation mechanism 64 to move left and right as a whole.

[0043] like Figure 5 As shown, the telescopic mechanism 5 in this embodiment uses a profile telescopic cylinder. The piston rod of the profile telescopic cylinder is connected to the side wall of the air bearing-carrying profile 6, and the profile telescopic cylinder drives the air bearing-carrying profile 6 to extend and retract. The telescopic mechanism 5 and the air bearing-carrying profile 6 share a base plate 9, which is slidably connected to the base 2 via a slider and a slide rail.

[0044] like Figure 5 As shown, the extraction and release power mechanism 61 of this embodiment includes an extraction and release motor 611, a rotating shaft 612, and a drive roller 613. The extraction and release motor 611 is fixed to the end of the air expansion bearing carrier profile 6. One end of the rotating shaft 612 is connected to the motor shaft of the extraction and release motor 611, and the other end of the rotating shaft 612 is rotatably connected to the air expansion bearing carrier profile 6 via a bearing. Alternatively, the structure of the extraction and release motor 611 plus a reducer can be used to drive the rotating shaft 612. The drive roller 613 is fixed on the rotating shaft 612. The extraction and release motor 611 drives the drive roller 613 to rotate through the rotating shaft 612. When the air expansion shaft 7 is extracted, the drive roller 613 rotates forward, and when the air expansion shaft 7 is placed, the drive roller 613 rotates in reverse.

[0045] like Figure 5 As shown, the pressing mechanism 63 in this embodiment includes a pressing cylinder 631, a swing arm 632, a vertical plate 633, a pressing roller 634, and a pressing roller shaft 635. The pressing cylinder 631 is fixed on the air bearing carrier profile 6. One end of the swing arm 632 is hinged to the piston rod of the pressing cylinder 631, and the other end of the swing arm 632 is connected to the pressing roller shaft 635. The middle part of the swing arm 632 is hinged to the vertical plate 633, which is fixed on the air bearing carrier profile 6. The pressing roller 634 is mounted on the pressing roller shaft 635. The extension and retraction of the pressing cylinder 631 drives the swing arm 632 to swing up and down, and the swing arm 632 drives the pressing roller 634 to press or release the air shaft 7 on the driving roller 613.

[0046] like Figure 6As shown, the inflation / deflation mechanism 64 of this embodiment includes an inflation / deflation telescopic cylinder 641, an air nozzle telescopic cylinder 642, an air nozzle 643, an air nozzle mounting base 644, and a limit switch 645. The inflation / deflation telescopic cylinder 641 is fixed on the air expansion bearing carrier profile 6. The air nozzle telescopic cylinder 642 is connected to the piston rod of the inflation / deflation telescopic cylinder 641. The air nozzle mounting base 644 is connected to the piston rod of the air nozzle telescopic cylinder 642. The air nozzle 643 is fixed on the air nozzle mounting base 644. The limit switch 645 is fixed on the air nozzle mounting base 644 and located above the air nozzle 643. Before the shaft pulling action begins, the inflation / deflation telescopic cylinder 641 extends the air nozzle telescopic cylinder 642, and then the air nozzle telescopic cylinder 642 extends the air nozzle 643 and the limit switch 645. When the end of the air shaft 7 touches the limit switch 645, the air nozzle 643 is also inserted into the air hole of the air shaft 7, and the limit switch 645 sends a deflation signal to deflate the air shaft 7. After deflation, the air nozzle telescopic cylinder 642 and the inflation / deflation telescopic cylinder 641 retract sequentially, and the shaft pulling action begins. After the air shaft 7 is fully inserted into the core 8, the inflation / deflation telescopic cylinder 641 and the air nozzle telescopic cylinder 642 extend sequentially. When the limit switch 645 touches the end of the air shaft 7, the air nozzle 643 is also inserted into the air hole of the air shaft 7, and the limit switch 645 sends an inflation signal to inflate the air shaft 7. After inflation, the air nozzle telescopic cylinder 642 and the inflation / deflation telescopic cylinder 641 retract sequentially.

[0047] like Figure 7 , 8 As shown in Figure 9, the die buffer hopper 20 of this embodiment includes a storage plate 201, a support 202, a blocking mechanism, and a receiving mechanism. A first support plate 203 is provided in the middle of the support 202. The bottom of the storage plate 201 is slidably connected to the first support plate 203 via a slider and a slide rail, allowing the position of the storage plate 201 to be adjusted according to production needs. The storage plate 201 can store multiple dies 8 to be wound. The feed end of the storage plate 201 is higher than the discharge end, allowing the dies 8 to be wound to automatically roll from the feed end to the discharge end. The blocking mechanism is installed at the discharge end of the storage plate 201. The blocking mechanism releases the dies 8 to be wound one by one from the storage plate 201, and then the receiving mechanism receives the dies 8 released from the storage plate 201.

[0048] like Figure 8 , 9As shown in Figure 10, the blocking mechanism of this embodiment includes a set of front blocking components 206 and two sets of rear blocking components 207. A second support plate 204 is provided on the top of the bracket 202. A third support plate 205 is slidably connected to the second support plate 204 via a slider and a slide rail. The position of the third support plate 205 can be adjusted according to production needs. The front blocking components 206 are fixed on the second support plate 204, and the two sets of rear blocking components 207 are fixed on the third support plate 205. The front blocking components 206 and the rear blocking components 207 have the same structure, consisting of a blocking cylinder 2061 and a baffle 2062. The baffle 2062 is connected to the piston rod of the blocking cylinder 2061. First, the baffles of the two sets of rear blocking components 207 extend downward to block the discharge end of the storage plate 201. Then, all the core tubes 8 to be wound are stored on the storage plate 201. The core tubes 8 to be wound automatically roll to the baffle of the rear blocking components 207. Next, the baffle of the front blocking assembly 206 extends downwards. At this point, the first die 8 is released between the three baffles of the front blocking assembly 206 and the rear blocking assembly 207. Finally, the baffles of the last two sets of rear blocking assemblies 207 retract, allowing the first die to roll onto the receiving mechanism. Through the cooperation of the front blocking assembly 206 and the rear blocking assembly 207, the dies 8 can be placed onto the receiving mechanism one by one.

[0049] like Figure 7 , 8As shown in Figures 9 and 10, the receiving mechanism of this embodiment includes a material preparation box 208, a receiving cylinder 209, a receiving plate 210, and a gripper assembly. The top of the material preparation box 208 is fixed on the third support plate 205, and the two receiving cylinders 209 are fixed on the bottom of the material preparation box 208. The receiving plate 210 is connected to the piston rod of the receiving cylinder 209. The bottom of the two side walls of the material preparation box 208 is provided with slots 211 for the air shaft 7 to pass through. The slider and slide rail of the gripper assembly are slidably connected to the side walls of the material preparation box 208, and a set of gripper assemblies is provided on each of the two side walls. The gripper assembly consists of a gripper horizontal movement cylinder 215, a gripper telescopic cylinder 212, a bidirectional cylinder 213, and grippers 214. The gripper telescopic cylinder 212 is slidably connected to the side wall of the material preparation box 208 via a slider and a slide rail. The gripper telescopic cylinder 212 can move left and right. The bidirectional cylinder 213 is fixed on the piston rod of the gripper telescopic cylinder 212. A gripper 214 is fixed on each of the two piston rods of the bidirectional cylinder 213. The gripper telescopic cylinder 212 drives the two grippers 214 to move up and down. The bidirectional cylinder 213 drives the two grippers 214 to perform clamping and releasing operations of the air shaft. After the receiving cylinder 209 extends the receiving plate 210, the receiving plate 210 can be used to receive the tube core 8 released from the storage plate 201. Then, the air shaft feeding mechanism sends the air shaft 7 into the tube core 8. After the air shaft 7 is inflated, the chuck 214 clamps both ends of the air shaft 7, the receiving cylinder 209 retracts the receiving plate 210, then the gripper extension cylinder 212 lowers the air shaft 7 with the tube core 8 sleeved on it, and the gripper horizontal movement cylinder 215 drives the air shaft 7 with the tube core 8 sleeved on it to move, such as... Figure 11 As shown, this allows the air shaft 7, on which the core tube 8 is fitted, to fall into the groove of the placement plate 216 after the chuck 214 is released.
