[0034] The following is combined with Figure 1-5 The utility model is further described.

[0035] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0036] Reference Figures 1 to 5 , this technical solution provides an empty roll winding device for realizing the independent winding operation of the winding equipment (adopting the pneumatic shaft winding model) to realize the automation of winding, thereby reducing labor costs and reducing the mutual interference between multiple devices. The empty roll winding device includes an empty roll placement mechanism 120 and an upper manipulator 360, wherein the empty roll placement mechanism 120 is used to stack the empty rolls 8 to be loaded, and the upper manipulator 360 is used to transport the empty rolls 8 on the empty roll placement mechanism 120 to the winding equipment. The empty roll placement mechanism 120 includes a frame 1, which is the installation base of the entire empty roll placement mechanism 120 and is used to install and support various components. It can be a gantry, frame or other structural form, and is not limited here, as long as it can achieve the above-mentioned effects.

[0037] Reference Figures 1 to 3A loading movable frame 11 is tiltedly arranged on the frame 1. A loading head 12 is arranged on the side of the loading movable frame 11 close to the upper manipulator 360. The loading movable frame 11 is tilted downwardly toward the upper head 12. The loading head 12 is used to support both ends of the empty reel 8. The empty reel 8 on the empty roll placement mechanism 120 is transferred to the loading head 12 for the upper manipulator 360 to clamp and transport. The loading movable frame 11 has a frame structure and is tilted toward the upper head 12. A plurality of loading springs 2 are rotatably connected and installed on the opposite sides of the loading movable frame 11. The loading springs 2 are evenly arranged along the transmission direction of the empty reel 8. The loading springs 2 are used to transfer the empty reel 8 to the loading head 12. The upper end surface of the loading spring 2 is an arc-shaped structure. When the empty reel 8 is placed on the loading spring piece 2 on the side away from the loading head 12, due to the inclined setting of the loading movable frame 11, the empty reel 8 will roll downward along the inclined direction of the loading movable frame 11, that is, roll from the loading spring piece 2 on the side away from the loading head 12 to the loading spring piece 2 on the side close to the loading head 12. The loading movable frame 11 is provided with a driving member for driving the loading spring piece 2 located at the bottom of the loading movable frame 11 (that is, the loading spring piece 2 closest to the loading head 12) to rotate.

[0038] Furthermore, two loading fixed plates 111 are fixedly connected to the loading movable frame 11. The two loading fixed plates 111 extend along the transmission direction of the empty reel 8 and are arranged parallel to each other. The loading fixed plates 111 are fixedly connected to fixed pins 112. Multiple fixed pins 112 are evenly fixed on the loading fixed plates 111. The loading springs 2 are arranged in a one-to-one correspondence with the fixed pins 112. The loading springs 2 are provided with rotation holes, and the fixed pins 112 are rotatably connected to the rotation holes. The loading fixed plates 111 are also fixedly provided with limit pins corresponding to the loading springs 2. The loading springs 2 are provided with a limited waist-shaped hole 21 on the side away from the loading head 12. The limit pin extends into the limited waist-shaped hole 21. The limit pin cooperates with the limited waist-shaped hole 21 to limit the rotation of the loading springs 2.

[0039] Furthermore, the side of the feeding shrapnel 2 close to the feeding head 12 is the head, and the side away from the feeding head 12 is the tail. The driving part is the shrapnel cylinder 22. The shrapnel cylinder 22 is fixedly arranged on the frame 1 and is located on the side close to the feeding head 12. The piston rod of the shrapnel cylinder 22 is connected to the tail of the feeding shrapnel 2 located at the bottom. When the piston rod of the shrapnel cylinder 22 is extended, the tail of the feeding shrapnel 2 is driven to swing upward. At this time, the empty reel 8 located obliquely above the feeding shrapnel 2 will conflict with the tail of the feeding shrapnel 2, thereby achieving the purpose of restricting the empty reel 8 obliquely above from continuing to roll downward.

[0040] In this embodiment, the side of the feeding spring piece 2 away from the feeding head 12 is heavier than the side close to the feeding head 12. Specifically, the feeding spring piece 2 is centered on the fixing pin 112, and the weight of the fixing pin 112 of the feeding spring piece 2 to the tail of the feeding spring piece 2 will be greater than the weight of the fixing pin 112 of the feeding spring piece 2 to the head. When there is no empty reel 8 placed on the feeding spring piece 2 (i.e., it is empty), under the action of gravity, the feeding spring piece 2 will rotate around the fixing pin 112, and the tail will be lower than the head (i.e., the tail is swinging down). At this time, the empty reel 8 on the upper adjacent feeding spring piece 2 can roll onto the feeding spring piece 2 under the action of gravity. The feeding spring piece 2 is pressed by the empty reel 8 and will be in a tail-swinging state to prevent the upper adjacent empty reel 8 from rolling down again.

[0041] Furthermore, a proximity switch 121 is provided on the loading head 12, and the proximity switch 121 is connected to the signal of the shrapnel cylinder 22. When the empty roll 8 rolls into position on the loading head 12, the proximity switch 121 sends an in-position signal to the shrapnel cylinder 22. After receiving the in-position signal sent by the proximity switch 121, the shrapnel cylinder 22 starts to move and drives the loading shrapnel 2 to rotate on the fixing pin 112.

[0042] The stacking process of multiple empty reels 8 in the present invention is as follows: when the empty reel 8 is placed on the empty reel placement mechanism 120, the empty reel 8 will slowly roll downward under the action of its own gravity until it rolls onto the loading head 12. When the empty reel 8 rolls into position, the proximity switch 121 on the loading head 12 sends an in-position signal. After the shrapnel cylinder 22 receives the in-position signal, the piston rod extends to drive the loading shrapnel 2 to rotate a certain angle around the fixed pin 112, so that the tail of the loading shrapnel 2 swings upward a certain angle, restricting the empty reel 8 on the adjacent loading shrapnel 2 from rolling forward further. The adjacent empty reel 8, due to its own gravity, will press on the head of the corresponding loading shrapnel 2, so that the tail of the loading shrapnel 2 also swings upward, again restricting the empty reel 8 behind, and so on, to achieve the stacking of multiple empty reels 8 on the empty reel placement mechanism 120.

[0043] Reference Figure 1 and Figure 2 Furthermore, the side of the loading movable frame 11 close to the loading head 12 is hinged to the frame 1, and the side of the loading movable frame 11 away from the loading head 12 is provided with a screw adjustment assembly 7. One end of the screw adjustment assembly 7 is hinged to the loading movable frame 11, and the other end is detachably connected to the frame 1. By adjusting the screw adjustment assembly 7, the height of the loading movable frame 11 is propped up and the angle between the loading movable frame 11 and the horizontal plane is adjusted. Due to the different masses of the wound empty reels 8 of different materials, the speed at which the loading movable frame 11 rolls downward along the inclined setting will vary. In order to ensure that the rolling speed of the empty reels 8 of different materials is within a safe speed range, the inclination of the loading movable frame 11 can be adjusted by the screw adjustment assembly 7 to control the rolling speed of the empty reels 8.

[0044] Furthermore, alignment movable plates 13 are provided on opposite sides of the loading movable frame 11, and alignment driving cylinders 14 are fixedly connected on opposite sides of the loading movable frame 11. The alignment movable plates 13 are fixedly provided on the piston rods of the alignment driving cylinders 14. The piston rods of the alignment driving cylinders 14 on both sides are synchronously extended to drive the alignment movable plates 13 on both sides to move toward each other (i.e., move toward each other); when the piston rods of the alignment driving cylinders 14 on both sides are synchronously retracted, the alignment movable plates 13 on both sides are driven to move away from each other (i.e., move away from each other).

[0045] When the first empty roll 8 rolls onto the loading head 12, the alignment drive cylinders 14 fixed on both sides are started, pushing the alignment movable plates 13 on both sides to move synchronously toward the middle, and performing an axial position correction on the empty roll 8 so that the upper manipulator 360 can accurately clamp and transport the empty roll 8, thereby ensuring the reliability of the transportation of the empty roll 8.

[0046] Furthermore, the loading movable frame 11 is symmetrically fixed with limit plates 15 on both sides. The limit plates 15 are used to limit the two ends of the empty reel 8, so that the empty reel 8 is always located in the space defined by the limit plates 15 on both sides during the process of rolling downward along the loading movable frame 11, thereby reducing the possibility of the empty reel 8 falling off during the rolling process, and also limiting the possibility of the empty reel 8 moving axially during the rolling process, thereby effectively ensuring the rolling stability of the empty reel 8.

[0047] Reference Figure 2 、 Figure 4 and Figure 5 The upper manipulator 360 includes a support frame 3 arranged parallel to both sides of the top of the frame 1. A clamping assembly 4 is provided on the top of the support frame 3. The clamping assembly 4 is used to clamp the two ends of the empty roll 8 to achieve the transportation of the empty roll 8. The clamping assembly 4 is connected to a translation drive assembly 5 that can move left and right along the support frame 3 and a lifting drive assembly 6 that can be lifted up and down. The translation drive assembly 5 drives the clamping assembly 4 to move horizontally toward or away from the empty roll placement mechanism 120; the lifting drive assembly 6 drives the clamping assembly 4 to move vertically toward or away from the empty roll placement mechanism 120. The clamping assembly 4 includes a clamping claw 41 and a hook claw 42 rotatably connected to the end of the clamping claw 41. The clamping claw 41 is rotatably connected to a clamping cylinder 43 that drives the hook claw 42 to rotate. The clamping claw 41 and the hook claw 42 cooperate with each other to clamp the empty roll 8.

[0048] Specifically, the middle portion of the hook 42 is rotatably connected to the end of the clamping jaw 41. The clamping cylinder 43 is disposed on one side of the clamping jaw 41, and the piston rod of the clamping cylinder 43 is rotatably connected to one end of the hook 42. When the piston rod of the clamping cylinder 43 is extended, the hook 42 is driven to rotate away from the end of the piston rod of the clamping cylinder 43 toward the side closer to the clamping jaw 41, thereby closing the clamping assembly 4 and achieving the clamping action. When the piston rod of the clamping cylinder 43 is retracted, the hook 42 is driven to rotate away from the end of the piston rod of the clamping cylinder 43 toward the side away from the clamping jaw 41. At this time, the clamping assembly 4 is in an open state, and the empty reel 8 can be taken and placed.

[0049] Furthermore, the translation drive assembly 5 includes a crossbeam 51 and a horizontal drive motor 52. The two ends of the crossbeam 51 are slidably connected to the support frame 3. The horizontal drive motor 52 is fixedly mounted on the crossbeam 51. Drive shafts 521 are connected to the output ends of the horizontal drive motor 52 on opposite sides. The ends of the two drive shafts 521, away from the horizontal drive motor 52, are fixedly connected to horizontal drive gears 53. A horizontal rack 31 extending along the length of the support frame 3 is fixedly provided on the support frame 3, and the horizontal rack 31 meshes with the horizontal drive gear 53. When the horizontal drive motor 52 is started, it drives the drive shafts 521 on both sides to rotate, thereby driving the horizontal drive gear 53 to move on the horizontal rack 31, and further driving the crossbeam 51 to slide on the support frame 3.

[0050] In this embodiment, a horizontal slide rail 32 extending along the length direction of the support frame 3 is fixedly connected to the support frame 3, horizontal connecting blocks 511 are fixedly connected at both ends of the beam 51, a horizontal slider 513 sliding on the horizontal slide rail 32 is fixedly connected to the horizontal connecting block 511, a horizontal bearing 512 is fixedly connected to the horizontal connecting block 511, and the end of the transmission shaft 521 away from the horizontal drive motor 52 is rotatably connected to the horizontal connecting block 511 through the horizontal bearing 512.

[0051] The lifting drive assembly 6 includes a vertical plate 61 and a vertical drive motor 62. The vertical drive motor 62 is fixedly mounted on the crossbeam 51. Two vertical plates 61 are slidably mounted on opposite sides of the crossbeam 51 and arranged parallel to each other. The two vertical plates 61 can slide up and down vertically on the crossbeam 51. The clamping jaw 41 assembly is fixedly mounted at the bottom of the vertical plate 61. Connecting shafts 621 are connected to opposite sides of the output end of the vertical drive motor 62. The end of the connecting shaft 621 away from the vertical drive motor 62 is fixedly connected to a vertical drive gear 63. A vertical rack 611 is fixedly connected to the vertical plate 61. The vertical rack 611 extends along the length of the vertical plate 61, and the vertical drive gear 63 meshes with the vertical rack 611. When the vertical drive motor 62 is activated, it drives the connecting shafts 621 on both sides to rotate, thereby driving the vertical drive gear 63 to move on the vertical rack 611, causing the vertical plate 61 to slide up and down on the crossbeam 51, thereby achieving the lifting and lowering action of the clamping jaw 41 assembly.

[0052] In this embodiment, vertical rails 612 are fixedly mounted on the vertical plate 61 and extend along the length of the vertical plate 61. Vertical mounting blocks 514 are fixedly connected to opposite sides of the crossbeam 51. Vertical sliders 515 are fixedly connected to the vertical mounting blocks 514. The vertical rails 612 are slidably connected to the vertical sliders 515. A bearing mount is also fixedly connected to the crossbeam 51. A vertical bearing 516 is fixedly connected to the bearing mount. The end of the connecting shaft 621, which is remote from the vertical drive motor 62, is rotatably connected to the bearing mount via the vertical bearing 516.

[0053] The empty roll 8 of the utility model is handled in the following manner: after the winding roll rolls into place on the loading head 12, the clamping cylinder 43 is started to open the clamping assembly 4; then the clamping assembly 4 rises to the highest position under the drive of the vertical drive assembly; then the horizontal drive motor 52 is started to drive the clamping assembly 4 to move horizontally along the support frame 3 toward the direction close to the empty roll placement mechanism 120 to the top of the empty roll 8; then under the action of the vertical drive motor 62, the clamping assembly 4 is lowered to the reeling position. After the clamping assembly 4 is lowered into place, the clamping cylinder 43 drives the clamping assembly 4 to be closed to achieve the clamping of the empty roll 8; then the clamping assembly 4 is raised to the highest position under the drive of the vertical drive motor 62, and the empty roll 8 is transported to the top of the empty roll installation position by the horizontal drive motor 52; the vertical drive motor 62 is started again to move the empty roll 8 to the empty roll installation position, and the clamping assembly 4 is released so that the empty roll 8 falls into the empty roll installation position, i.e., the taking and placing action of the empty roll 8 is completed.

[0054] When the empty reel 8 on the loading head 12 is taken away by the upper manipulator 360, the shrapnel cylinder 22 is started, so that the piston cylinder of the shrapnel cylinder 22 is retracted, thereby driving the tail of the lowest loading shrapnel 2 to swing downward a certain distance. At this time, the empty reel 8 adjacent to the lowest loading shrapnel 2 breaks away from the blocking limit of the tail of the lowest loading shrapnel 2, and rolls onto the lowest loading shrapnel 2 under the action of its gravity. After the empty reel 8 on the loading shrapnel 2 adjacent to the lowest loading shrapnel 2 rolls out, its tail end also swings downward a certain distance, so that the rear empty reel 8 rolls down to this adjacent loading shrapnel 2, and so on, to realize the downward transmission of the empty reel 8, and then cooperate with the clamping and transportation of the upper manipulator 360 to realize the automation of winding, reduce the time loss in the winding process, and enable the winding operations between multiple devices to be completed independently, while effectively reducing labor costs.

[0055] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments.
