Description

Technical Field

[0001] This utility model relates to the technical field of AGV handling systems, specifically to a limiting device for positioning and hanging wires in conjunction with a wire-dropping trolley. Background Technology

[0002] Doffing is a crucial step in silk reeling production, where small or large sheets of wound silk are removed from the equipment. Recognizing the huge potential market for AGVs in the textile industry, our company has independently designed a doffing AGV and a series of production solutions and supporting equipment for its application in the silk reeling workshop. This includes the process of unloading the doffing AGV after docking with existing silk hanging trolleys in the textile industry.

[0003] Existing wire-hanging trolleys lack brakes and fixed placement stations. Due to their specialized function, their construction is also quite unique, with a 25mm height difference between their casters and directional wheels, making it impossible for them to be balanced on the ground on their own. However, AGV docking requires precise fixed stations, and a certain degree of stability and consistency must be maintained during unloading, which existing wire-hanging trolleys cannot meet. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a limiting device for positioning and hanging wire on a wire-feeding trolley. Through precise mechanical guidance and limiting, it guides the wire-feeding trolley quickly, accurately, and smoothly into a predetermined working position and maintains stability there, facilitating subsequent wire hanging operations. This achieves multi-dimensional control of the trolley's movement trajectory, effectively solving the problems of low efficiency, poor accuracy, and safety hazards associated with traditional manual positioning.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions: A limiting device for positioning and hanging wire on a wire-feeding trolley includes a limiting assembly. The limiting assembly has a wire-feeding trolley frame. Universal wheels are provided between the front and rear ends of the wire-feeding trolley frame and the limiting assembly. Directional wheels are provided on both the left and right sides of the middle section of the wire-feeding trolley frame between the limiting assembly and the limiting assembly. The limiting assembly includes a front platform and a rear platform. A pair of flared universal wheel guide rails are provided on the rear platform. Baffles are provided on both sides between the front and rear platform to limit the directional wheels.

[0006] Preferably, both sides of the front platform and both sides of the rear platform are provided with several anchor bolt holes.

[0007] Preferably, the front end of the front platform is provided with a ramp plate that is integrated with the front platform.

[0008] Preferably, both ends of the front platform are provided with directional wheel guides integrated with the front platform, and the directional wheel guides extend to be flush with the front end of the ramp.

[0009] Preferably, the front end of each baffle is provided with an anti-slip block that is integrally welded to the guide rail of the directional wheel and flush with the lower end face of the guide rail of the directional wheel.

[0010] Preferably, a buffer block is provided between the upper front end of the baffle and the directional wheel, and is fixed to the baffle with screws.

[0011] Preferably, the rear end of the universal wheel guide rail is provided with several headplate holes.

[0012] This invention can achieve the following effects: This invention provides a limiting device for positioning and hanging wire on a wire-feeding trolley. Compared with existing technologies, it customizes ground protrusions based on the wheelbase and height difference of the wire-feeding trolley to compensate for the height difference, and guides the wire-feeding trolley onto the ground protrusions through guide baffles. Simultaneously, it restricts the left-right and forward-backward movement space of the wire-feeding trolley, thereby limiting its four degrees of freedom. By combining components such as omnidirectional wheels, directional wheels, guide rails, baffles, and buffer blocks, multi-dimensional control of the trolley's movement trajectory is achieved, effectively solving the problems of low efficiency, poor accuracy, and safety hazards associated with traditional manual positioning.

[0013] High precision and high efficiency: By combining "coarse positioning at the horn mouth + fine positioning on the guide rail", the positioning accuracy of the trolley is improved from relying on manual experience to the level of mechanical assurance, which significantly shortens the positioning time and increases the production cycle.

[0014] High safety and reliability: The design of the anti-slip block 12 is the finishing touch. It provides a passive and absolutely reliable anti-slip protection, fundamentally eliminating related safety accidents. Multiple limits (side baffles, end buffers, and rigid blocks) ensure stable and reliable equipment operation.

[0015] Optimized structure and user-friendly design: The ramp 14 reduces the difficulty of going uphill; the buffer block 6 enables impact-free stopping, protecting the equipment and improving the operating experience. The split platform facilitates installation and maintenance.

[0016] Modular and integrated design: Key components such as guide rails, baffles, and anti-slip blocks adopt integrated or welded designs, which ensures the structural strength and dimensional accuracy of the entire device and reduces positioning deviations caused by loose connections.

[0021] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0022] Example: Figure 1 , Figure 2 and Figure 3 As shown, a limiting device for positioning and hanging wire with a wire-feeding trolley includes a limiting component 4. A wire-feeding trolley frame 2 is mounted on the limiting component 4. Universal wheels 1 are provided between the front and rear ends of the wire-feeding trolley frame 2 and the limiting component 4. Directional wheels 3 are provided on the left and right sides of the middle section of the wire-feeding trolley frame 2 between it and the limiting component 4. The limiting component 4 includes a front platform plate 5 and a rear platform plate 8. Four anchor bolt holes 11 are provided on both sides of the front platform plate 5 and both sides of the rear platform plate 8. A ramp plate 14, integrated with the front platform plate 5, is provided at the front end of the front platform plate 5. A pair of flared universal wheel guide rails 9 are provided on the rear end of the universal wheel guide rails 9. Three headplate holes 10 are provided at the rear end of the universal wheel guide rails 9. Baffles 7, which limit the directional wheels 3, are provided on both sides between the front platform plate 5 and the rear platform plate 8. A buffer block 6, screwed and fixed to the directional wheel 3, is provided between the upper front end of the baffle 7 and the directional wheel 3. Each baffle 7 has an anti-slip block 12 that is integrally welded to the guide rail 13 and flush with the lower end face of the guide rail 13. Both sides of the front platform 5 have guide rails 13 that are integrally welded to the front platform 5 and extend to be flush with the front end of the ramp 14.

[0023] Workflow: Entering stage: The operator pushes the wire dropping trolley so that its front wheels (swivel wheels 1) are aligned with the flared opening of the swivel wheel guide rail 9 on the rear platform 8.

[0024] Guiding Phase: Guided by the horn-shaped opening, the front end of the trolley is automatically corrected in direction. Simultaneously, the directional wheel 3 in the middle of the trolley moves onto the ramp 14 and enters the directional wheel guide rail 13. At this point, the trolley's trajectory is completely locked into a straight line.

[0025] During operation: The trolley moves in a straight line along the path formed by the universal wheel guide rail 9 and the directional wheel guide rail 13. The baffles 7 on both sides continuously provide lateral restraint to prevent swaying.

[0026] Positioning and buffering phase: When the trolley approaches the end point, the directional wheel 3 contacts the buffer block 6, and the trolley decelerates smoothly under the resistance of the buffer block until it stops at the predetermined working position.

[0027] Safety locking phase: After the trolley comes to a complete stop, its directional wheel 3 is blocked from behind by the anti-slip block 12, completely preventing any possibility of accidental slippage. At the same time, the trolley head can also contact the baffle installed on the head plate hole 10 to complete multiple positioning.

[0028] Wire hanging operation: The trolley is precisely and stably locked in the optimal position, allowing the operator to perform wire hanging operations safely and efficiently.

[0029] Exit phase: The operator only needs to push the trolley forward with a little force so that the directional wheel 3 passes the height of the anti-slip block 12 (or directly lift the trolley) and it can drive out of the limit device along the original path.

[0030] In summary, this limiting device for positioning and hanging wire on a wire-feeding trolley guides the trolley quickly, accurately, and smoothly into the predetermined working position through precise mechanical guidance and limiting, and maintains stability in this position to facilitate subsequent operations such as wire hanging. It achieves multi-dimensional control of the trolley's movement trajectory, effectively solving the problems of low efficiency, poor accuracy, and safety hazards associated with traditional manual positioning.
