The invention discloses an automatic file pocket shelving device. The device comprises a feeding trolley, a file cabinet, a grabbing manipulator, a horizontal moving mechanism and a vertical lifting mechanism, wherein the grabbing manipulator comprises a pneumatic finger, a third motor, a connecting rod, a first rotating cylinder, a connecting rod support, a second rotating cylinder and a second lead screw support; the vertical lifting mechanism comprises a first motor, a first ball screw, a first guide track, a first sliding block, a first lead screw support, a guide shaft and a linear bearing; and the horizontal moving mechanism comprises a second motor, motor supports, a lifting supporting plate, second ball screws and a second guide track. File pockets on the feeding trolley are shelved by the grabbing manipulator of the automatic file pocket shelving device. Compared with a traditional artificial file pocket storage mode, the automatic file pocket shelving device is more convenient, workload in a file arrangement process is greatly reduced, file neatening quality is improved, automation of management of files can be realized, and file management efficiency is improved effectively.
