Description

Technical Field

[0001] This utility model relates to the field of fabric transfer and packaging technology, and in particular to an automatic fabric packaging device. Background Technology

[0002] The finished fabric roll automatic packaging system relies on intelligent transfer robots to achieve efficient operation. The system obtains the fabric roll forming information at the end of the production line in real time through the central scheduling platform and generates the optimal packaging path instruction based on the preset algorithm. The transfer robot uses laser navigation and visual recognition fusion positioning technology to accurately reach the target workstation. It works in coordination with the robotic arm gripping device and the adaptive wrapping packaging system—the robotic arm relies on force control sensors to stably grasp the fabric roll core. Traditional packaging and transfer robots' curved lifting arm grippers lack an active fabric roll pivot limiting structure, relying solely on the curved surface for passive support. During operation, if they encounter ground obstacles, such as protruding interfaces, scattered parts, or need to stop abruptly, the robot will experience instantaneous jolts or tilting, causing the fabric roll to shift relative to the lifting arm due to inertia. At the same time, due to the lack of axial restraint devices, the fabric roll is very prone to rolling and slipping off the curved surface when subjected to lateral impact forces, causing the fabric roll to fall and cause damage or even production line interruption. This risk is particularly significant in scenarios involving the transfer of large-diameter, heavy fabric rolls. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automatic fabric packaging device, including a transport vehicle and a lifting assembly, wherein the lifting assembly includes a lifting arm rotatably mounted on the transport vehicle; wherein a contact plate is slidably mounted at the arc-shaped opening of the lifting arm, and an arc-shaped limiting toothed plate is slidably mounted along the arc-shaped path; in use, the contact plate is used to support the fabric roll, and the contact plate moves downward under force and drives the arc-shaped limiting toothed plate to extend out from the opening of the lifting arm through a linkage, thereby achieving a limiting action on the fabric roll.

[0005] In at least some embodiments, a housing is fixedly mounted on the upper part of the transport vehicle, the main body of the lifting assembly is located between the housing and the transport vehicle, and the lifting arm extends through the housing to the outside.

[0006] In at least some embodiments, a control box is also fixedly installed on one side of the transport vehicle. The control box is electrically connected to the transport vehicle and the lifting assembly respectively, so as to realize electrically controlled movement and lifting actions.

[0007] In at least some embodiments, the linkage includes a piston rod, which is slidably mounted inside an arc-shaped air box fixed inside the lifting arm via a spring. The piston rod passes through the arc-shaped air box and the lifting arm once, extending to the outside and being fixedly connected to the contact plate. An air pipe fixed to the output end of the arc-shaped air box performs an exhaust action when the contact plate is subjected to force and moves downward.

[0008] In at least some embodiments, the input end of the pneumatic telescopic rod fixed inside the lifting arm is connected to the arc-shaped air box through the air pipe, and a strip-shaped toothed plate is fixedly connected to the linkage plate fixed to the output end of the pneumatic telescopic rod. The strip-shaped toothed plate realizes pneumatic telescopic movement through the pneumatic telescopic rod. A first gear rotatably installed inside the lifting arm meshes with the strip-shaped toothed plate and a second gear rotatably installed inside the lifting arm, respectively. A third gear fixed to one side of the second toothed plate meshes with the arc-shaped limiting toothed plate, thereby realizing the pneumatic opening and closing action of the arc-shaped limiting toothed plate.

[0009] In at least some embodiments, an electric actuator is rotatably mounted on a support seat fixed to the upper part of the transport vehicle. A connecting arm rotatably mounted on the output end of the electric actuator is fixedly connected to a square rod rotatably mounted on the upper part of the transport vehicle. The lifting arm is fixed to the upper part of the square rod. In use, the electric actuator drives the lifting arm to perform a lifting action.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, after the transport vehicle moves to the fabric roll station, the lifting arm rotates to a horizontal supporting posture under the action of the drive mechanism. When the fabric roll core falls into the arc-shaped opening of the lifting arm, its own weight presses the sliding contact plate to move down along the arc-shaped track. During the downward movement of the contact plate, the arc-shaped limiting tooth plate is triggered by the linkage to extend synchronously from the lifting arm cavity. The movement trajectory of the arc-shaped tooth plate is completely matched with the curved surface of the lifting arm, and its tooth structure forms a surrounding limiting barrier on both sides of the fabric roll core. The whole process does not require an external power source and fully utilizes the self-weight of the fabric roll to achieve mechanical linkage locking, effectively preventing axial movement or rolling due to bumps during transportation.

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0015] Implementation examples, based on Figures 1-4 As shown, the automatic fabric packaging device provided in this embodiment of the present invention includes a transport vehicle 1 and a lifting assembly 4. The lifting assembly 4 includes a lifting arm 405 rotatably mounted on the transport vehicle 1. A contact plate 406 is slidably mounted at the arc-shaped opening of the lifting arm 405, and an arc-shaped limiting toothed plate 407 is slidably mounted along the arc-shaped path. In use, the contact plate 406 is used to support the fabric roll. The contact plate 406 moves downward under force and drives the arc-shaped limiting toothed plate 407 to extend out from the opening of the lifting arm 405 through the linkage, thereby realizing the limiting action of the fabric roll.

[0016] In the aforementioned automatic fabric packaging device, after the transport vehicle 1 moves to the fabric roll station, the lifting arm 405 rotates to a horizontal supporting posture under the action of the drive mechanism. When the fabric roll core falls into the arc-shaped opening of the lifting arm 405, its own weight presses the sliding contact plate 406 to move down along the arc-shaped track. During the downward movement of the contact plate 406, the arc-shaped limiting toothed plate 407 is triggered by the linkage to extend synchronously from the cavity of the lifting arm 405. The movement trajectory of the arc-shaped toothed plate is completely matched with the curved surface of the lifting arm 405, and its toothed structure forms a surrounding limiting barrier on both sides of the fabric roll core. The entire process does not require an external power source and fully utilizes the self-weight of the fabric roll to achieve mechanical linkage locking, effectively preventing axial movement or rolling due to bumps during transportation.

[0017] In this embodiment, a housing 2 is fixedly installed on the upper part of the transport vehicle 1. The main body of the lifting assembly 4 is located between the housing 2 and the transport vehicle 1, and the lifting arm 405 extends through the housing 2 to the outside. A control box 3 is also fixedly installed on one side of the transport vehicle 1. The control box 3 is electrically connected to the transport vehicle 1 and the lifting assembly 4 respectively to realize electrically controlled movement and lifting actions. An electric push rod 402 is rotatably installed on the support seat 401 fixed on the upper part of the transport vehicle 1. A connecting arm 403 rotatably installed on the output end of the electric push rod 402 is fixedly connected to a square rod 404 rotatably installed on the upper part of the transport vehicle 1. The lifting arm 405 is fixed on the upper part of the square rod 404. When in use, the lifting arm 405 is driven by the electric push rod 402 to perform lifting actions.

[0018] After receiving the packing instruction, the control system of control box 3 allows transport vehicle 1 to autonomously drive to the roll-making station via the navigation module; After positioning is completed, the control box 3 starts the lifting program - the base of the electric push rod 402 is fixed on the support base 401, and its output end pushes the connecting arm 403 to make a fan-shaped movement. Since the connecting arm 403 is rigidly connected to the square rod 404, and the square rod 404 forms a rotating pair with the chassis of the transport vehicle 1 through the bearing seat, the telescopic movement of the electric push rod 402 is converted into the precise angular rotation of the square rod 404 through the connecting arm 403. The lifting arm 405, fixed to the upper end of the square rod 404, swings synchronously, rotating from the vertical standby position to the horizontal support position; when the cloth roll is placed in the arc groove of the lifting arm 405 by external equipment, its own weight triggers the mechanical limit mechanism, and the contact plate 406 presses down to drive the arc toothed plate to extend, thereby locking the shaft core. The control box 3 synchronously receives the pressure sensor signal and, after confirming that the load is stable, instructs the transport vehicle 1 to drive to the target area. Upon reaching the destination, the electric push rod 402 retracts in the opposite direction, causing the lifting arm 405 to slowly descend to the unloading height. The electromagnetic release device of the limit mechanism unlocks, and the cloth roll is released from the lifting arm 405 to complete the delivery. The entire process is managed through the integrated control box 3, which manages motion control, sensor feedback, and safety interlock logic to achieve automated operation.

[0019] In this embodiment, the linkage includes a piston rod 409. The piston rod 409 is slidably mounted inside the arc-shaped air box 408 fixed inside the lifting arm 405 via a spring. The piston rod 409 passes through the arc-shaped air box 408 and the lifting arm 405 and extends to the outside, where it is fixedly connected to the contact plate 406. The air pipe 410 fixed to the output end of the arc-shaped air box 408 performs an exhaust action when the contact plate 406 is subjected to force and moves downward. The input end of the pneumatic telescopic rod 411 fixed inside the lifting arm 405 is connected to the arc-shaped air box 408 via the air pipe 410. A linkage plate 412, which is fixed to the output end of the pneumatic telescopic rod 411, is fixedly connected to a strip-shaped toothed plate 413. The strip-shaped toothed plate 413 achieves pneumatic telescopic movement through the pneumatic telescopic rod 411. A first gear 414, which is rotatably installed inside the lifting arm 405, meshes with the strip-shaped toothed plate 413 and a second gear 415, which is rotatably installed inside the lifting arm 405. A third gear 416, which is fixed to one side of the second toothed plate, meshes with an arc-shaped limiting toothed plate 407, thereby achieving the pneumatic opening and closing action of the arc-shaped limiting toothed plate 407.

[0020] The linkage achieves the limiting function through a combination of pneumatic and gear transmission: when the cloth roll core is inserted into the arc-shaped opening of the lifting arm 405, the weight of the core presses the contact plate 406 downward, pushing the piston rod 409 to compress the spring in the arc-shaped air box 408 and slide it into the air box. The displacement of piston rod 409 reduces the volume of arc-shaped air box 408, and the internal air is discharged through the output air pipe 410, forming an airflow pulse; The airflow is transmitted through the air pipe 410 to the input end of the pneumatic telescopic rod 411, which pushes the internal piston to move, causing the output end of the pneumatic telescopic rod 411 to extend, thereby driving the linkage plate 412 and the strip toothed plate 413 fixed at its end to move forward. The linear motion of the strip-shaped toothed plate 413 drives the first gear 414 meshing with it to rotate. The first gear 414 synchronously drives the second gear 415 to rotate in the opposite direction. The second gear 415 meshes with the tooth profile of the arc-shaped limiting toothed plate 407 through the third gear 416 connected coaxially. The rotation of the third gear 416 converts linear transmission into arc-shaped trajectory motion, pushing the arc-shaped limiting tooth plate 407 outward from the inner cavity of the lifting arm 405 along the preset arc-shaped track, and finally wrapping the two sides of the cloth roll core to form a mechanical limit. When the fabric roll is removed, the pressure on the contact plate 406 disappears, the spring inside the arc-shaped air box 408 pushes the piston rod 409 to reset, the air box draws in air through the air inlet valve to form a negative pressure, the spring inside the pneumatic telescopic rod 411 retracts to the output end, the linkage plate 412 drives the strip toothed plate 413 to move backward, and the gear system rotates in the opposite direction to make the arc-shaped limiting toothed plate 407 retract into the lifting arm 405. The entire process achieves adaptive limiting through the mechanical linkage of air circuit and gears, requiring no electric power, and has both buffering and self-locking characteristics.

[0021] The working principle of this utility model is as follows: After the transport vehicle 1 moves to the fabric roll station, the lifting arm 405 rotates to a horizontal supporting posture under the action of the drive mechanism; when the fabric roll core falls into the arc-shaped opening of the lifting arm 405, its own weight presses the sliding contact plate 406 to move down along the arc-shaped track. During the downward movement of the contact plate 406, the arc-shaped limiting tooth plate 407 is triggered by the linkage to extend synchronously from the cavity of the lifting arm 405. The movement trajectory of the arc-shaped tooth plate is completely matched with the curved surface of the lifting arm 405, and its tooth structure forms a surrounding limiting barrier on both sides of the fabric roll core. The whole process does not require an external power source and fully utilizes the self-weight of the fabric roll to achieve mechanical linkage locking, effectively preventing axial movement or rolling due to bumps during transportation.

[0022] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
