The invention discloses a medicine bottle buffer storage system. The medicine bottle buffer storage system comprises a medicine bottle transmission device and a medicine bottle storage device, wherein the medicine bottle transmission device comprises a medicine bottle arranging mechanism and a medicine bottle pushing mechanism; the medicine bottle pushing mechanism is used for pushing medicine bottles arranged on the medicine bottle arranging mechanism to a buffer storage platform of the medicine bottle storage device. The medicine bottle storage device is used for storing the medicine bottles which are freeze-dried and capped, so that a worker can carry out manual lamp inspection after working normally, and can continuously work after a freeze-dried tank body is discharged; when the capping speed is greater than the lamp inspection speed, the medicine bottles of the same batch are subjected to lamp inspection while being stored onto the buffer storage platform, and the medicine bottles on the buffer storage platform are further pushed out for being continuously subjected to lamp inspection after the capping work is ended, and therefore, the production efficiency is improved, and the equipment usage rate is increased.
