Doffing apparatus for buffer storing wound packages

A method for doffing wound packages by means of a doffing apparatus for removing wound packages comprising a synthetic thread, which can be wound by a winding apparatus with a winding spindle onto a sleeve to form at least one wound package, having a buffer-storing apparatus,

• wherein the buffer-storing apparatus has:
• a push-off apparatus for pushing wound packages off the winding spindle,
• a wound-package store for buffer storing the wound package,
• a depositing device for depositing the wound package in the wound-package store, wherein, by means of an impulse movement of the depositing device, the wound package can be deposited in the wound-package store by way of the circumferential surface (U) of the wound package,
• wherein the wound packages are formed in the winding apparatus, comprising the following steps:
• winding a synthetic thread onto an empty sleeve, which is fixed temporarily on a winding spindle,
• moving the depositing device from a parking position (P) to a depositing position (A),
• pushing off the wound package by means of the push-off apparatus,
• depositing the wound package on the depositing device,
• moving the wound package into a storage compartment of the wound-package store,
• wherein the movement of the wound package into the wound-package store is carried out by means of an impulse movement of the depositing device and by way of the circumferential surface (U) of the wound package.

A spinning-stretching-texturing apparatus for producing crimped synthetic threads comprising a spinning device and a plurality of machine devices assigned to the spinning device and a plurality of winding apparatuses comprising a doffing apparatus for removing wound packages comprising a synthetic thread, which can be wound by a winding apparatus with a winding spindle onto a sleeve to form at least one wound package, having a buffer-storing apparatus, wherein the buffer-storing apparatus has:

• a push-off apparatus for pushing wound packages off the winding spindle,
• a wound-package store for buffer storing the wound package,
• a depositing device for depositing the wound package in the wound-package store, wherein, by means of an impulse movement of the depositing device, the wound package can be deposited in the wound-package store by way of the circumferential surface (U) of the wound package,
• which are configured to carry out a method for doffing wound packages, wherein synthetic threads with a denier count in the range of from 850 to 12000 dtex, can be produced by means of the spinning-stretching-texturing apparatus.
