Detailed Implementation

[0014] 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.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a centering lifting rotary conveyor table, the base 1 including a base frame 1.1, guide rails 1.3 fixed laterally to the top surface of the base frame 1.1 near the four corners, and a rack 1.4 fixed laterally to the middle of the rear of the base frame 1.1. Vertical frames 1.2 are fixedly connected to the four corners of the top surface of the base frame 1.1.

[0016] The centering conveyor assembly 2 includes four belt conveyor modules 2.1 arranged in a rectangular array above the base frame 1.1, forming a cross-shaped cavity structure. Each belt conveyor module 2.1 has a slider 2.9 fixed to its bottom, which slides and engages with a guide rail 1.3. A U-shaped frame 2.7 is fixedly connected between the front ends of the two front belt conveyor modules 2.1, and a fixed beam 2.4 is fixedly connected between the rear ends of the two rear belt conveyor modules 2.1. A synchronous transmission mechanism 2.2 is connected to the outer sides of the two belt conveyor modules 2.1 on the same side. A conveyor motor 2.3 is installed at the bottom inner side of the synchronous transmission mechanism 2.2 on one side, driving the corresponding synchronous transmission mechanism 2.2. A coupling 2.8 is fixedly connected between the rollers of the two front belt conveyor modules 2.1, and the conveyor motor 2.3 is driven by the corresponding synchronous transmission mechanism. The structure 2.2 can drive the operation of its two front and rear belt conveyor modules 2.1. The front belt conveyor module 2.1 drives the left belt conveyor module 2.1 through the coupling 2.8. The left synchronous transmission mechanism 2.2 can realize the synchronous operation of the two left belt conveyor modules 2.1. The synchronous transmission mechanism 2.2 is composed of multiple synchronous pulleys and synchronous belts, or multiple sprockets and synchronous chains, so that one conveyor motor 2.2 can drive four belt conveyor modules 2.1 to operate synchronously and in the same direction. The transverse motor 2.5 is fixed to the front wall of the fixed beam 2.4. The power output shaft of the transverse motor 2.5 is fixedly fitted with a gear 2.6 that meshes with the rack 1.4. By driving the gear 2.6 to rotate through the transverse motor 2.5, the transverse sliding of the entire centering conveyor assembly 2 can be realized by utilizing the meshing relationship between the gear 2.6 and the rack 1.4.

[0017] The lifting and rotating assembly 3 includes a base plate 3.1 fixed to the bottom of the cross-shaped cavity between the belt conveyor modules 2.1, a lifting plate 3.2 that moves vertically relative to the base plate 3.1, a slewing bearing 3.4 with its inner ring fixed to the top surface of the lifting plate 3.2, a support frame 3.8 fixed to the top surface of the outer ring of the slewing bearing 3.4 and located between the paired belt conveyor modules 2.1, and a power component for driving the slewing bearing 3.4 to rotate the outer ring. Telescopic cylinders 3.3 are vertically fixedly mounted at the four corners of the lifting plate 3.2, and the bottom ends of the piston rods of the telescopic cylinders 3.3 are fixedly connected to the bottom surface of the base plate 3.1. The slewing bearing 3.4 is an external gear type slewing bearing. A connecting frame 3.9 is fixed to one side of the lifting plate 3.2. A rotary motor 3.5 is fixedly installed on the outside of the connecting frame 3.9. A commutator 3.6 is fixedly installed on the inside of the connecting frame 3.9, with the power input shaft and the power output shaft of the rotary motor 3.5 fixedly connected. A gear 3.7, which meshes with the rotating outer ring of the slewing bearing 3.4, is fixedly fitted on the top of the power output shaft of the commutator 3.6. The support frame 3.8 is cross-shaped. The extension and retraction of the telescopic cylinder 3.3 enables the lifting plate 3.2 to move up and down relative to the base plate 3.1. The rotary motor 3.5, commutator 3.6, and gear 3.7 facilitate the rotation of the outer gear ring of the slewing bearing 3.4, thereby achieving the steering adjustment of the support frame 3.8. Due to the large transmission ratio between the gear and the slewing bearing, the transmitted torque is large, which enables the equipment to rotate smoothly and be accurately positioned.

[0018] Four pairs of through-beam photoelectric sensors are installed on the inner top of the vertical frame 1.2.

[0019] Both the conveyor motor 2.3 and the rotary motor 3.5 are servo motors to ensure the stability of the kinetic energy provided and to facilitate the adoption of a full servo closed-loop control system for the entire machine, thereby achieving intelligent and precise control.

[0020] In summary, during use, the centering lifting rotary conveyor is equipped with conveying equipment at both the front and rear ends. The object is transported from the rear end to the centering conveyor assembly 2 by the rear conveying equipment. The belt conveyor module 2.1 works in conjunction with the conveying equipment to transport the object until the object is completely supported by the belt conveyor module 2.1.

[0021] The transverse motor 2.5 operates to drive the centering conveyor assembly 2 and the lifting and rotating assembly 3 to move laterally as a whole, so that the center of the object is aligned with the centerline of the conveying equipment in front, thus completing the transverse centering operation of the object.

[0022] When conveying objects forward, the belt conveyor module 2.1 uses two sets of front and rear photoelectric modules 4 to measure the length of the objects. In conjunction with the belt conveyor module 2.1, the objects can be conveyed forward or backward to facilitate longitudinal alignment of the objects.

[0023] By performing lateral and longitudinal centering operations, the center of the object is easily aligned with the center of the support frame 3.8. At this time, the piston rod of the telescopic cylinder 3.3 extends, allowing the support frame 3.8 to smoothly lift the object. The rotary motor 3.5 drives the outer ring of the slewing bearing 3.4 to rotate through the commutator 3.6 and gear 3.7, thereby enabling the support frame 3.8 to rotate horizontally while carrying the object, thus achieving the operation of reorienting the object. For example, rotating the slewing bearing 3.4 180° enables the object to be turned around.

[0024] After the object is repositioned, the piston rod is retracted by the telescopic cylinder 3.3 so that the repositioned object can be placed back on the conveyor belt of the belt conveyor module 2.1, thus completing the centering, lifting and rotation operation of the object in one go.
