[0002] The doffing of fine yarn is an important part of the production in the fine yarn workshop. All the work of the doffer is carried out around high quality, high yield and low consumption. After the doffing is completed, most of the yarn rolls are taken from the doffing equipment by a mechanical arm and placed in the temporary storage device in the doffing machine for temporary storage. When the temporary storage device is full, it has a heavy weight, and the manual pushing method makes it difficult to push it conveniently in the production area, causing the operator to spend time and energy on the transfer operation.
