Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of automatic palletizing devices, specifically an automatic palletizing device for logistics unloading. Background Technology
[0002] Automatic palletizing equipment is a type of automated equipment mainly used to automatically stack packaged items into stacks according to a preset arrangement. It is suitable for logistics, warehousing and industrial production. In the process of yarn spindle production and processing, in order to improve the efficiency of yarn spindle stacking, cantilever palletizing equipment is often used to assist in stacking.
[0003] An investigation revealed that a Chinese utility model patent (publication number: CN221587276U) discloses an automatic palletizing device for unloading and transporting goods in logistics. This device includes a robotic arm and further comprises: a hydraulic telescopic cylinder assembly installed at the end of the robotic arm; a vacuum adsorption plate fixedly installed at the telescopic end of the hydraulic telescopic cylinder assembly; a concave plate fixedly connected to the hydraulic telescopic cylinder assembly; and a compression airbag ring fixedly connected to the concave plate near the vacuum adsorption plate and sleeved onto the hydraulic telescopic cylinder assembly. Compared to existing technologies that rely solely on the adsorption plate for palletizing and transferring objects, this utility model provides secondary clamping and fixing of objects during movement and palletizing, further improving the fixation effect and preventing objects from falling during movement. This effectively enhances the protection of the objects and reduces economic losses.
[0004] Although the aforementioned patent can improve the fixation effect of objects by secondary clamping, its adaptability is reduced. When producing and stacking yarn spindles, the clamping and fixing effect is low because the yarn spindles have a cylindrical structure. At the same time, when stacking yarn spindles, adjacent yarn spindles are affected by the clamps and cannot achieve tight stacking, resulting in loose stacking of yarn spindles and reducing their stacking firmness.
[0005] Therefore, this utility model provides an automatic palletizing device for unloading goods in logistics to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] like Figures 1-6As shown, this utility model provides an automatic palletizing device for logistics unloading, including a support component 1, which includes a hydraulic cylinder 11. The lifting end of the hydraulic cylinder 11 is fixedly connected to a rotary cylinder 12, and the driving end of the rotary cylinder 12 is fixedly connected to a support arm 13. There are also an adjustment component 2 and a rotating component 3. The adjustment component 2 is located above the support arm 13 and is used for the horizontal driving adjustment of the rotating component 3. A gripping component 4 is installed at the bottom of the driving end of the rotating component 3 and is used for the horizontal rotation adjustment of the gripping component 4. The gripping component 4 is used for gripping and fixing the yarn spindles. By gripping the yarn spindles with the gripping component 4, and under the control and drive of the rotating component 3, the adjustment component 2, and the support component 1, the gripped yarn spindles are moved, thus achieving stacking of the yarn spindles with flexible displacement. The hydraulic cylinder 11 mainly adjusts the gripping height of the gripping component 4, and simultaneously works with the rotary cylinder 12 to rotate the support arm 13, increasing its gripping range.
[0035] Furthermore, a reinforcing arm 14 is fixedly connected to the outer wall of the support arm 13, and the other end of the reinforcing arm 14 is rotatably connected to the outside of the telescopic end of the hydraulic cylinder 11 through a ball bearing. The horizontal end of the support arm 13 is provided with a through groove adapted to the horizontal displacement of the rotating component 3. By setting the reinforcing arm 14, the stability and firmness of the support arm 13 can be improved.
[0036] Furthermore, the adjustment assembly 2 includes a dual-head motor 21 and a support shaft 22. Both the dual-head motor 21 and the support shaft 22 are connected to the upper surface of the support arm 13. The output end of the dual-head motor 21 and the outside of the support shaft 22 are connected to two sets of synchronous belt drive mechanisms 23. An adjustment plate 24 is fixedly connected to the bottom of the synchronous belt drive mechanism 23, and the bottom of the adjustment plate 24 is horizontally slidably connected to the support arm 13 through a slide rail 25. Each synchronous belt drive mechanism 23 consists of two synchronous pulleys and a synchronous belt. The synchronous pulleys are respectively fixedly connected to the output shaft of the dual-head motor 21 and the outer wall of the support shaft 22. The two synchronous pulleys of the support shaft 22 are connected to the output shaft of the dual-head motor 21 and the outer wall of the support shaft 22. All ends are rotatably connected to the upper surface of the support arm 13 via bearing seats. There are two sets of slide rails 25, and each set of slide rails 25 includes a guide rail and two sliders. The guide rail is fixedly connected to the upper surface of the support arm 13, and positioning plates are provided at both ends of the guide rail. The sliders are fixedly connected to the lower surface of the adjustment plate 24. Driven by the dual-head motor 21, the synchronous belt transmission mechanism 23 can be driven to rotate. Furthermore, under the rotation of the synchronous belt transmission mechanism 23, the adjustment plate 24 can be driven to make horizontal sliding displacement, which can drive the rotating component 3 and the gripping component 4 to make horizontal displacement adjustment, so as to realize flexible adjustment of the gripping position.
[0037] Furthermore, the rotating assembly 3 includes an electric rotating table 31, which is fixedly connected to the upper surface of the adjusting plate 24.

A guide shaft 35 is fixedly connected to the upper surface of the support ring 34, and the guide shaft 35 slides through to the top of the adjusting plate 24. The electric rotating table 31 drives the telescopic cylinder 32 to rotate, and the positioning ring 33 drives the gripping assembly 4 to rotate and adjust, so as to avoid the gripping angle of the gripping assembly 4 from contacting the stacked spindles during the stacking process, thereby further improving the flexibility of spindle stacking.
[0038] Furthermore, the gripping component 4 includes a housing 41, which is fixedly connected to the lower surface of the positioning ring 33. A servo motor 42 is fixedly connected to the outer wall of the housing 41, and a first bevel tooth 43 is fixedly connected to the output end of the servo motor 42.

A gripping rod 50 is threadedly connected to the bottom of the claw 49. The claw 49 has evenly distributed circumferences. The four gripping rods 50 have anti-slip rubber sleeves on their outer walls. The guide plate 48 has four sets of guide grooves around its circumference, and the inner wall of the guide grooves is provided with limiting protrusions. The claws 49 have limiting grooves at the corresponding limiting protrusions, and the claws 49 are horizontally slidably disposed inside the guide grooves. The first bevel tooth 43 is driven to rotate by the servo motor 42, and the rotating ring 44 is driven to rotate by the meshing of the second bevel tooth 45. While the rotating ring 44 is rotating, the claws 49 are pushed to move by the spiral groove 46, thereby realizing the gripping rods 50 moving closer or further apart. The gripping rods 50 can be used to clamp and position the yarn spindle. At the same time, the adjustability of the gripping rods 50 allows the gripping assembly 4 to be adapted to grip yarn spindles of different diameters for flexible gripping.
[0039] Working principle: Driven by hydraulic cylinder 11 and rotary cylinder 12, the gripping component 4 is moved to the yarn spindle gripping area. Further, by adjusting the displacement of component 2, the gripping component 4 is coaxially distributed with the yarn spindle. Through the lowering cooperation of telescopic cylinder 32 and hydraulic cylinder 11, the gripping component 4 completes the gripping of the yarn spindle. When the gripped yarn spindle moves to the stacked yarn spindle, the gripping component 4 is rotated by driving the electric rotary table 31, so that the gripping rod 50 is placed in the gap between adjacent yarn spindles. At this time, when the gripped yarn spindle is placed, the tightness of the yarn spindle stack can be ensured.
