The invention relates to a pallet fork system of a stacking machine, in particular to a safety type multi-stage pallet fork for a stacking machine. The safety type multi-stage pallet fork for the stacking machine comprises a cargo carrying table base and further comprises a telescopic pallet fork unit, a driving unit and a pallet fork tail end detection unit which are arranged on the cargo carrying table base, wherein the driving unit is connected with the telescopic pallet fork unit and used for driving the telescopic pallet fork unit to stretch out and draw back; and the tail end detection unit is connected with the telescopic pallet fork unit and used for detecting the telescopic displacement of the telescopic pallet fork unit. The telescopic pallet fork unit comprises a lower-layer pallet fork, a middle-layer pallet fork and an upper-layer pallet fork which are sequentially connected in a sliding mode, the lower-layer pallet fork is connected with the cargo carrying table base, andthe upper-layer pallet fork is connected with the pallet fork tail end detection unit. The safety type multi-stage pallet fork for the stacking machine has high safety and reliability, and can improve safety of equipment operation under the working conditions that the position of a tray object is abnormal or a transmission mechanism is accidentally damaged due to mechanical fatigue.
Description
technical field [0001] The invention relates to a pallet fork system of a stacker, in particular to a multi-stage pallet fork for a safe stacker. Background technique [0002] At present, pallet forks for stackers are mostly used in the storage and transfer of product pallets in automated warehouses. In order to ensure that the telescopic fork has a sufficient stroke and save the length of the fork mechanism itself, the fork for the stacker mostly adopts a multi-stage cable transmission form. Whether it is a steel wire rope, a synchronous belt or a chain, when used as a multi-stage fork transmission cable, there is a risk of transmission failure such as loosening or breaking. Generally, multi-stage transmission forks for stackers require regular maintenance, tightening or replacement of transmission cables. However, this method cannot fundamentally prevent the occurrence of safety accidents. [0003] At present, there are a large number of intelligent storage needs in the ...
