Loading and unloading mechanism

Abstract

A loading and unloading mechanism is provided on a take-up and drop-down machine. The mechanism includes a lifting device, multiple floating discs, and a cover-opening mechanism. The lifting device has a lifting platform, with multiple floating discs located on the outside of the platform and connected to it. The lifting platform is driven to rise and fall, and has multiple positioning pins for positioning a carrier. Multiple locking mechanisms are also provided on the platform to lock and secure the carrier. The cover-opening mechanism is located at one end of the lifting device. The carrier is transported to the loading and unloading mechanism. After the floating discs rise to receive the carrier and the entire frame, they lock the carrier. Then, the lifting platform rises to receive the carrier, and the floating discs release the carrier. A translational power source (such as a rodless cylinder) then pushes the lifting platform forward to the cover-opening mechanism, which opens the cover of the carrier. By integrating the floating discs into the lifting platform, the structure is simplified, space is saved, and the problem of asynchronous lifting and lowering of the floating discs by separate cylinders is avoided.

Claims

1. A loading and unloading mechanism, comprising: A lifting device includes a base, a lifting platform, a lifting drive mechanism, and a translational power source. The lifting platform is disposed on the base, the lifting drive mechanism is connected to the base, and the lifting drive mechanism can drive the base and the lifting platform to lift. The translational power source is connected between the base and the lifting platform. Multiple floating disks are disposed on the outside of the lifting platform and connected to the lifting platform, so that the multiple floating disks can move up and down synchronously with the lifting platform; The device includes a cover-opening mechanism located at one end of the lifting device. The plurality of floating discs can be pushed upwards by the lifting drive mechanism to receive the carrier. After the carrier is positioned, the plurality of floating discs can lock the carrier, and the lifting drive mechanism drives the lifting platform upwards to receive the carrier. The plurality of floating discs can release the carrier, and the lifting platform can lift the carrier to a predetermined height. The translational power source drives the lifting platform forward, allowing it to be transported to the cover-opening mechanism to open the cover of the carrier.
