Description

Technical Field

[0001] The invention belongs to the technical field of mechanical suspension conveying devices, and in particular relates to a three-dimensional conveying device of a suspension conveying system. Background Art

[0002] Overhead conveyor systems are a common type of continuous conveying equipment, widely used to continuously transport hangers or various items. They are also used in assembly lines across various industrial sectors to transport workpieces between processes, completing various processes and achieving comprehensive mechanization of conveying and processing operations. Overhead conveyor systems fully utilize three-dimensional space to achieve efficient transportation within limited space. They are advanced, flexible, and highly automated conveying equipment, playing an increasingly important role in modern large-scale production.

[0003] Typically, manufacturing plants require the storage, transportation, and allocation of materials. However, existing technologies employ a single-layer material storage structure, resulting in a single material transportation method and low space utilization efficiency. When a multi-layer material storage structure is employed due to production process requirements, line switching becomes a challenge. Using turnouts or fixed tracks for line switching results in long and time-consuming transport distances, low efficiency, and the risk of congestion, which impacts the efficiency of the conveying system and makes it unsuitable for transporting materials with significant classification changes. Summary of the Invention

A transport vehicle carrying materials is provided on the conveyor track and moves along the conveyor track; the transverse drive drives the driving belt to rotate, and drives the lifting mechanism connected to the driving belt to move along the driving belt and move horizontally back and forth; the lower frame is driven up and down by the lifting drive, and at the same time the scissors fork between the upper frame and the lower frame slides, retracts or opens, reducing the load-bearing capacity of the driving belt and strengthening the connection strength between the upper frame and the lower frame, thereby driving the conveyor track connected to the lower frame to rise and fall, and completing the three-dimensional transportation of materials through the transverse mechanism, lifting mechanism and conveyor track, and can dock different conveyor lines according to the process, thereby improving space utilization efficiency, improving work efficiency, and making production more orderly.

[0006] Furthermore, in the three-dimensional conveying device of the aforementioned suspended conveying system, the transverse frame includes first columns, crossbeams, and connecting beams. The first columns are located at the four corners of the transverse frame. Crossbeams are connected transversely above the first columns, and connecting beams are connected longitudinally to the first columns.

The second drive is fixed to the outer support seat of the upper frame. The rotating shaft is connected to the second drive via a coupling. The two ends of the rotating shaft are provided with seat bearings fixed to the upper frame and are rotatably connected to the upper frame via the seat bearings.

[0051] if Figure 6-7 As shown, buffer sleeves 351 cooperating with the upper frame 31 are provided on both sides of the lower frame 34 to reduce the vibration caused by inertia when the lower frame 34 rises to the upper position and stops. Second buffer blocks 352 are provided at both ends of the second linear slide 341 to reduce the vibration caused by inertia when the scissors fork 33 stops, thereby extending the service life of the equipment and reducing the vibration on the conveying track 4 to prevent materials from falling on the conveying track 4. Second proximity switches 353 and second limit switches 354 fixed to the upper frame 31 are provided at both ends of the outer side of the second linear slide 341 to control the stroke of the scissors fork 33. Combined with the lifting stroke of the lower frame 34, the stopping position of the lower frame 34 can be more accurately controlled, so that the docking position of the conveying track 4 is more accurate.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
