[0006] The outer pull rod assembly is adapted to move up and down above the umbrella closing area. It includes an outer pull rod group with the same number of umbrella ribs. The outer pull rod group is adapted to extend into the umbrella fabric and move outward along the radial direction of the umbrella rotation axis to cooperate with the inner pressure rod assembly to smooth the umbrella fabric. It can also retract and move inward along the radial direction of the umbrella rotation axis during rotation and rolling to roll up the umbrella fabric. The umbrella fabric is adapted to drive the binding strap to roll around during rotation so that the binding strap automatically rolls around the outside of the umbrella fabric.

[0007] Furthermore, the inner pressure rod assembly includes a claw device that rotates synchronously with the umbrella and has the same number of outer umbrella ribs as the umbrella itself, and an inner pressure rod connected to the claw device and having the same number as the outer umbrella ribs. The claw device is connected to a swinging device, which is adapted to drive the claw device and the inner pressure rod to swing synchronously to press or release the outer umbrella ribs.

[0008] Furthermore, the swinging device includes a swinging motor and a rack installed on the periphery of the umbrella positioning center sleeve. The swinging motor is adapted to drive the rack to move up and down. One end of the claw device is connected to a gear that meshes with the rack. The gear is hinged on the placement station. The swinging device and the inner pressure rod are controlled by the swinging motor driving the rack to move up and down.

[0009] Furthermore, it also includes a flexible cable tie assembly disposed above the umbrella closing area and an outer umbrella rib sleeve adapted to be fitted over the umbrella shaft for fixing the upper end of the umbrella; wherein, the outer umbrella rib sleeve is provided with a sleeve lifting structure to independently drive the outer umbrella rib sleeve to lift and lower, and the outer umbrella rib sleeve is connected to a sleeve rotating shaft to drive the outer umbrella rib sleeve to rotate; the flexible cable tie assembly includes a cable tie lifting mechanism, a tensioning motor connected to the cable tie lifting mechanism, the tensioning motor being connected to a tensioning rack structure for controlling the unfolding diameter and tightening diameter of the flexible cable tie installed on the tensioning rack structure, the unfolding diameter being suitable for fitting all umbrella ribs at the umbrella handle end, and the tightening diameter being such that the outer umbrella rib sleeve can lock all umbrella ribs at the umbrella handle end.

[0010] Furthermore, the flexible cable tie assembly is disposed on one side of the outer pull rod assembly, and the flexible cable tie is sleeved on the outside of the outer umbrella rib sleeve.

[0011] Furthermore, the outer pull rod assembly is connected to the lifting assembly, which includes a lifting sliding mechanism. The outer pull rod assembly, the flexible cable tie assembly, and the outer umbrella rib sleeve are all connected to the lifting sliding mechanism.

[0012] Furthermore, the outer tie rod assembly includes a synchronous motion mechanism, and the outer tie rods are evenly distributed on the synchronous motion mechanism, which drives the outer tie rods to rotate synchronously.

[0013] Furthermore, a pull rod moving motor is connected to the outer pull rod assembly, and the pull rod moving motor is adapted to control the outer pull rod to move inward and outward along the radial direction of the umbrella rotation axis.

[0014] The present invention also provides an automatic umbrella rewinding method, which utilizes the aforementioned automatic umbrella rewinding device and includes the following steps:

[0015] Insert the umbrella into the umbrella positioning center sleeve of the first station and place the umbrella strap on the strap fixing component. Then the station exchange device is electrically activated, so that the first station and the second station are automatically exchanged and the first station enters the winding position.

[0016] The lifting assembly automatically descends to clamp the umbrella with the outer rib clips, and the inner pressure rod assembly swings to press and position the outer ribs; the outer pull rod assembly inserts the outer pull rod into the umbrella fabric, and the outer pull rod assembly moves outward along the radius of the umbrella's rotation axis to smooth the umbrella fabric.

[0017] During the rolling process, the rotating mounting device and the outer umbrella rib clamping device drive the umbrella to rotate in a set direction. During the rotation, the outer pull rod group moves inward according to the preset motion relationship so that the umbrella cloth is gradually rolled up with appropriate tension to ensure that the umbrella cloth is flat and tightly rolled up. During the umbrella cloth rolling process, the strap fixing component is pulled to move inward a preset distance along the radius of the umbrella rotation axis, and the strap is wrapped around the outside of the umbrella cloth. After the umbrella is rolled up, the strap is pulled off from the strap fixing component, so that the Velcro (or snap fastener, etc.) on the strap is automatically tightened (fastening the strap).

[0018] While the umbrellas are being rolled up in the first station, another umbrella is inserted into the umbrella positioning center sleeve in the second station. After the first station completes the umbrella rolling process and the second station completes the umbrella loading, the station exchange device is restarted to exchange the first and second stations, and the process is repeated to achieve uninterrupted production of rolled-up umbrellas.

[0019] Furthermore, after the outer umbrella rib clamps the umbrella, the inner pressure rod assembly first clamps the outer umbrella rib to diameter A. Then, the flexible cable tie assembly loosens the flexible cable tie to a diameter greater than A. Next, the cable tie lifting motor controls the flexible cable tie to descend to the position of the outer umbrella rib, so that the flexible cable tie is sleeved on the outside of the outer umbrella rib. Then, the flexible cable tie motor tightens the flexible cable tie to tighten the outer umbrella rib, so that the diameter of the outer umbrella rib after tightening is smaller than the diameter of the outer umbrella rib clamp. Finally, the outer umbrella rib clamp is driven to continue to descend to clamp on the outside of the outer umbrella rib.

[0020] Beneficial effects:

[0021] This solution enables automated umbrella rolling. By setting up a dual-station automatic exchange system, uninterrupted umbrella rolling production is achieved, significantly improving rolling efficiency. Multiple external pull rods with synchronized external and internal pull mechanisms (the same number of umbrella strands) and multiple internal pressure rods with internal and external tension mechanisms enable automatic fabric smoothing, winding, and strap securing. This results in neat and efficient umbrella rolling, suitable for the rolling processes of various folding umbrellas. Attached Figure Description

Detailed Implementation

[0027] Example 1

[0028] Combination Figures 1 to 4 As shown, this embodiment provides an automatic umbrella rewinding device, including: at least two placement stations for placing umbrellas 10, respectively defined as a first station 2 and a second station 3; a station exchange device connecting the first station and the second station 3 to drive the first station 2 and the second station 3 to alternately switch between an umbrella placement area 102 and an umbrella rewinding area 101; and an outer pull rod assembly 5 disposed above the umbrella placement area 102; wherein, each placement station includes a rotating mounting device 21 suitable for placing umbrellas 10, and the rotating mounting device 21 is provided with an inner pressure rod assembly 4 having the same number of umbrella ribs around its periphery; and an umbrella positioning center sleeve for holding umbrellas 10. The umbrella ribs are pressed onto the umbrella pole, and a strap fixing assembly 8 is provided on one side of each placement station for fixing the straps; the strap fixing assembly 8 is adapted to move along the radial direction of the umbrella 10 rotation axis during the umbrella 10 roll-up process; the outer pull rod assembly 5 is adapted to move up and down above the umbrella closing area 101, and includes an outer pull rod group 52 with the same number as the umbrella ribs, the outer pull rod group 52 is adapted to extend into the umbrella fabric 12 and move outward along the radial direction of the umbrella 10 rotation axis to cooperate with the inner pressure rod assembly 4 to smooth the umbrella fabric 12; and can retract and move inward along the radial direction of the umbrella 10 rotation axis during the rotation and rolling process to roll up the umbrella fabric 12.

[0029] Combination Figures 1 to 3As shown, in this embodiment, the automatic umbrella rewinding device includes a housing 1, on which a control panel 103 is provided, and an electrical cabinet assembly is provided inside. The control panel 103 can control the operation of the automatic umbrella rewinding device and adjust the corresponding parameters. A rewinding area 101 and a defrosting area 102 are formed inside the housing 1, and a partition is provided between the rewinding area 101 and the defrosting area 102. The first station 2 and the second station 3 are respectively adapted to switch between the rewinding area 101 and the defrosting area 102. When in the rewinding area 101, the umbrella fabric 12 can be rewinded; when in the defrosting area 102, the umbrella 10 to be rewinded can be placed on the umbrella positioning center sleeve 22 of the placement station, and the straps on the umbrella 10 can be placed on the strap fixing assembly 8 for fixation.

[0030] Combination Figures 1 to 4 As shown, in this embodiment, an umbrella positioning center sleeve 22 is provided at the placement station for mounting and placing the umbrella 10. Specifically, the end of the umbrella shaft of the umbrella 10 can be placed inside the umbrella positioning center sleeve 22 for initial positioning. A rotating shaft connected to a rotating motor is provided below the umbrella positioning center sleeve 22 for driving the umbrella positioning center sleeve 22 to rotate, thereby causing the umbrella 10 placed on the umbrella positioning center sleeve 22 to rotate. An inner pressure rod assembly 4 is provided around the umbrella positioning center sleeve 22. The inner pressure rod assembly 4 includes a number of claw devices that rotate synchronously with the umbrella 10 and are equal in number to the number of outer umbrella ribs 11, and inner pressure rods 41 connected to the claw devices, which are equal in number to the number of outer umbrella ribs 11 of the umbrella 10. The claw devices are connected to a swinging device 42, which is adapted to drive the claw devices together with the inner pressure rods 41 to swing to press or release the outer umbrella ribs 11.

[0031] Specifically, the swinging device 42 includes a tensioning motor 421 and a rack 422 installed around the umbrella positioning center sleeve 22. The tensioning motor 421 is adapted to drive the rack 422 to move up and down. One end of the claw device is connected to a gear 423 that meshes with the rack 422. The gear 423 is hinged on the placement station. The tensioning motor 421 drives the rack 422 to move up and down to control the claw device and the inner pressure rod 41 to swing. The inner pressure rod 41 is equipped with a pressure head at one end, which is used to press the outer umbrella ribs 11 of the umbrella 10 toward the umbrella pole, so that each outer umbrella rib 11 is close to the umbrella pole, thereby facilitating roll-up; the other end of the inner pressure rod 41 is connected to the end of the claw device. The opening and closing motor 421 can be equipped with a drive gear 423. When the opening and closing motor 421 rotates, it can control the rack 422 to move up or down. The rack 422 is installed on the placement position and has a certain displacement gap. When the rack 422 moves up and down, it drives the gear 423 to rotate, thereby causing the claw device and the inner pressure rod 41 to swing around the central axis of the gear 423. Swinging outward causes the inner pressure rod 41 to loosen the pressure on the outer umbrella ribs 11, while swinging inward causes the inner pressure rod 41 to press the outer umbrella ribs 11. By setting the displacement gap, the swing angle of the inner pressure rod 41 can be expanded. The structure is simple to control and can fix the outer umbrella ribs 11 before the umbrella 10 is rolled up, keeping the outer umbrella ribs 11 in a fixed position during the rolling process.

[0032] Continue to combine Figures 1 to 4 As shown, a strap fixing assembly 8 is provided on one side of the placement station. The strap fixing assembly 8 is adapted to be displaced a certain distance along the radial direction of the rotation axis of the umbrella 10 under the drive of the umbrella fabric 12 during roll-up. Specifically, the strap fixing assembly 8 can be set on any side of the placement station and is located outside the inner pressure rod assembly 4. A sliding rail (not shown) is provided on the placement station for it to move. The strap fixing assembly 8 can slide inward along the sliding rail. At the same time, a spring (not shown) is provided on the sliding rail. The spring is connected to the strap fixing assembly 8 and can drive the strap fixing assembly 8 to reset when the strap is detached from the strap. During the winding process, the umbrella 10 rotates, causing the strap to wind up together. The strap fixing component 8 moves to a certain position. When the umbrella fabric 12 is finished winding up, the Velcro on the strap automatically connects to the connecting part on the umbrella 10, completing the tightening of the strap. At this time, the umbrella 10 continues to rotate, so that the pulling force of the umbrella fabric 12 on the strap is greater than the frictional force of the strap fixing component 8 on the strap. The strap automatically disengages from the clamp of the strap fixing component 8, and then the strap fixing component 8 automatically resets.

[0033] Above the umbrella closing area 101, a flexible cable tie assembly 9 and an outer umbrella rib sleeve 6 for securing the upper end of the umbrella 10 are also provided. Above the umbrella closing area 101, a lifting assembly 7 is provided, which includes a lifting sliding mechanism 71. The outer pull rod assembly 5 is connected to the flexible cable tie assembly 9 and the outer umbrella rib sleeve 6 on the lifting sliding mechanism 71. The lifting assembly 7 can control the outer pull rod assembly 5, the flexible cable tie assembly 9, and the outer umbrella rib sleeve 6 to move up and down synchronously and quickly. Here, the outer pull rod assembly 5 is provided with a synchronous motion mechanism 51, and the outer pull rod groups 52 are evenly distributed on the synchronous motion mechanism 51, which drives the outer pull rod groups 52 to move synchronously. At the same time, the synchronous motion mechanism 51 is provided with an outer pull rod moving mechanism 53, which controls the outer pull rod groups 52 to move inward and outward along the radial direction of the umbrella 10's rotation axis on the synchronous motion mechanism 51. The external pull rod moving mechanism 53 can be implemented using a motor-driven rack and pinion mechanism, or other existing mechanisms. For example, pull rod moving mechanisms 53 corresponding to the number of umbrella ribs can be evenly distributed inside the external pull rod assembly 5. Each external pull rod mechanism 53 is fixed on a corresponding track and moves linearly along the radial direction. The pull rod moving mechanism 53 includes a drive motor and a gear structure. The drive motor drives the gears to mesh with a gear ring to synchronously push the pull rod moving mechanism. When the drive motor rotates forward, multiple pull rod moving mechanisms move inward synchronously; when it rotates in reverse, they move outward synchronously. It should be noted that the external pull rod group 52 is evenly distributed circumferentially on the outside of the outer umbrella rib sleeve 6. When the external pull rod of the external pull rod assembly 5 is inserted into the umbrella fabric 12, it can move outward to straighten the umbrella fabric 12. Then, during the rolling process, the external pull rod moves inward simultaneously during rotation according to a given motion relationship, ensuring that the umbrella fabric 12 is neat and aesthetically pleasing when rolled up. The motion relationship can be adaptively adjusted according to the length of the umbrella fabric 12.

[0034] In this embodiment, the outer umbrella rib retainer 6 is provided with a retainer lifting structure 61 to independently drive the outer umbrella rib retainer 6 to rise and fall, and the outer umbrella rib retainer 6 is connected to a retainer rotating shaft to drive the outer umbrella rib retainer 6 to rotate; through the outer umbrella rib retainer 6, the outer umbrella rib 11 can be limited in advance with the inner pressure rod 41 before rolling, so that when the outer umbrella rib 11 is displaced from the limit of the inner pressure rod 41 during the rolling process, the outer umbrella rib 11 can be tightened. The retainer rotating shaft rotates synchronously with the rotating motor that drives the umbrella positioning center sleeve 22 to rotate, jointly driving the umbrella 10 to rotate. Here, the outer umbrella rib retainer 6 is also sleeved on the end of the umbrella pole for positioning and fixing the umbrella pole.

[0035] The flexible cable tie assembly 9 includes a cable tie lifting mechanism 91 and a tensioning motor 94 connected to the lifting mechanism 91. The tensioning motor 94 is connected to a tensioning rack structure 93 to control the unfolding diameter of the flexible cable tie 92 mounted on the rack structure. Here, the flexible cable tie assembly 9 is located on one side of the outer pull rod assembly 5, and the flexible cable tie 92 is sleeved on the outside of the outer umbrella rib retainer 6. The flexible cable tie 92 is used to sleeve on the outside of the outer umbrella rib 11 to tighten the outer umbrella rib 11 during winding. This assists in the outer umbrella rib retainer 6 being sleeved on the outside of the outer umbrella rib 11 and also keeps the outer umbrella rib 11 in a tightened state during winding.

[0036] The automatic umbrella 10 rewinding device of this embodiment can continuously rewind the umbrella 10 with high efficiency and high neatness after rewinding.

[0037] It should be noted that in this embodiment, the outer pull rod and the inner pressure rod 41 are replaceable to accommodate umbrellas 10 of different sizes. The umbrella 10 described in this embodiment can be a folding umbrella, and it is designed for rolling up after folding. It can also be used for rolling up long, straight umbrellas.

[0038] Example 2

[0039] The present invention also provides an automatic umbrella rewinding method, which utilizes the aforementioned automatic umbrella rewinding device and includes the following steps:

[0040] Insert the umbrella 10 into the umbrella positioning center sleeve 22 of the first station 2, and place the umbrella 10 strap on the strap fixing assembly 8. Then the station exchange device is electrically activated, so that the first station 2 and the second station 3 are automatically exchanged, and the first station 2 enters the winding position.

[0041] The lifting assembly 7 automatically descends to clamp the umbrella 10 with the outer umbrella rib sleeve 6, and the inner pressure rod assembly 4 swings to press and position the outer umbrella rib 11; the outer pull rod assembly 5 inserts the outer pull rod into the umbrella fabric 12, and the outer pressure rod assembly moves outward along the radius of the umbrella 10 rotation axis to smooth the umbrella fabric 10.

[0042] During the winding process, the rotating mounting device and the outer umbrella rib clamp drive the umbrella to rotate in a set direction. The outer pull rod assembly 5 moves inward according to a preset motion relationship so that the umbrella fabric is gradually wound up with appropriate tension to ensure that the umbrella fabric is flat and tightly wound. During the winding process, the rotating mounting device 21 and the outer umbrella rib clamp 6 drive the umbrella 10 to rotate in the opposite direction to increase the winding speed. During the winding process of the umbrella fabric 12, the strap fixing assembly 8 is pulled to move inward a preset distance along the radius of the umbrella 10 rotation axis so that the strap is wrapped around the outside of the umbrella fabric 12, so that the Velcro on the strap is automatically tightened. After the umbrella 10 is wound up, the strap is pulled off the strap fixing assembly 8.

[0043] While the umbrella 10 is being rolled up in the umbrella-collecting area 101 at the first station 2, another umbrella 10 is inserted into the umbrella positioning center sleeve 22 at the second station 3. After the first station 2 completes the umbrella 10 rolling process and the second station 3 completes the umbrella loading, the station exchange device is restarted to exchange the first station 2 and the second station 3, and so on, to achieve uninterrupted production of rolled-up umbrellas 10.

[0044] In a preferred embodiment, when fixing the outer umbrella rib 11, after the outer umbrella rib retainer 6 clamps the end of the umbrella shaft of the umbrella 10, the inner pressure rod assembly 4 first clamps the outer umbrella rib 11 to a diameter of A. Then, the flexible cable tie assembly 9 first loosens the flexible cable tie 92 to a diameter greater than A. Next, the cable tie lifting motor controls the flexible cable tie 92 to descend to the position of the outer umbrella rib 11, so that the flexible cable tie 92 is fitted onto the outside of the outer umbrella rib 11. Then, the flexible cable tie 92 motor tightens the flexible cable tie 92 to tighten the outer umbrella rib 11, so that the diameter of the tightened outer umbrella rib 11 is smaller than the diameter of the retainer 6. Then, the outer umbrella rib retainer 6 is driven to continue descending to clamp onto the outside of the outer umbrella rib 11. This method ensures that each outer umbrella rib 11 remains in a predetermined position during fixing and rewinding. Once the winding is complete, the flexible cable tie 92 is released by the motor and driven to move upward by the cable tie lifting mechanism 91 to move away from the area of ​​the umbrella 10, making it easier for the next winding operation.

[0045] The solution in this embodiment is simple and easy to implement. Through automatic exchange between two workstations, uninterrupted production of rolled-up umbrellas 10 can be achieved, which greatly improves the rolling efficiency and the aesthetics of the rolled-up umbrellas.

[0046] It should be understood that the above are merely preferred embodiments of the present invention, and the scope of protection of the present invention is not limited to the above embodiments. All technical solutions that fall within the scope of the present invention are within the scope of protection of the present invention.

[0047] The accompanying drawings used in the above description of the embodiments only illustrate certain embodiments of the present invention and should not be regarded as a limitation of the scope.
