Technical field
The present invention relates to a kind of bobbin change device that is used for Speed frames, specifically, relate to following a kind of bobbin change device that is used for Speed frames, these Speed frames have the bobbin rail that can vertically install with being shifted, and flier rail with fixed and arranged, the flier of this flier rail all is equipped with central spindle blade, described bobbin change device is equipped with the replacing platform, but this replacing platform is installed in the mode of horizontal shift and is had connecting gear, and this connecting gear has the base that is used for carrying hangingly roving bobbin and empty sleeve pipe.
Background technology
As is known, on Speed frames, form roving bobbin to processing by so-called drawing frame production and by the ribbon that the fibrous material of substantially parallel layout is formed.In other words, still the ribbon of thick relatively feeding is further stretched on this Speed frames and is formed the less twist, so that guarantee to have higher-strength.Usually the roving bobbin that will produce on Speed frames by so-called suspension type vehicle frame group is transported to ring spinner then, and spinning cop is processed into roving bobbin in the place at ring spinner.
In such Speed frames, because the exchange (being also referred to as the process of doffing) of full roving bobbin and new empty sleeve pipe is not to be inappreciable expenditure aspect work, so developed the various bobbin change devices that combine and use with such Speed frames, part has described this bobbin change device in detail in patent documentation.
For example described the bobbin change device that is used for Speed frames in EP0912781B1, as traditional Speed frames, these Speed frames have the bobbin rail of the installation of can vertically moving and the flier rail of fixed and arranged.
The bobbin change device of this known Speed frames has a large amount of guide rails, and this guide rail extends in the Speed frames from behind, can introduce empty sleeve pipe in the Speed frames or can transport rearwards from Speed frames expiring roving bobbin by these guide rails.According to the structure of Speed frames, the guide rail of bobbin change device or directly be fixed to the flier rail or be arranged on the long support member, this long support member is fastened on from below on the flier rail.In this case, these guide rails extend below the flier of Speed frames slightly.
As can be seen, particularly as can be seen from Fig. 1 c of EP0912781B1, this known Speed frames have bobbin rail, this bobbin rail has long spindle blade, the shortcoming of this Speed frames is, for the roving bobbin between the spindle blade of the flier that can eject the flier rail and bobbin rail, must construct this Speed frames than the highland or in the mode of relative complex on the structure.For example being configured to according to the bobbin rail of the Speed frames of EP0912781B1, bobbin rail can also slightly be shifted to a side.
