Description
Technical field
This utility model belongs to technical field of textile machine, particularly relates to a kind of drawing frame creeling protection device.
Background technology
In drawing frame work process, output sliver encloses after draft of drawing frame and is wound in output bars cylinder.Rapid advances recently as cotton spinning, it is desirable to drawing frame speed constantly promotes, therefore in the case of the output bars cylinder constancy of volume, the time that the most completely cylinder needs is the most shorter and shorter, and operator needs to be replaced as frequently as bar cylinder, and labor intensity increases considerably.Therefore, a lot of cotton mills have begun to the output bars cylinder (output bars cylinder diameter of phi >=1000mm, the biggest bar cylinder) using capacity bigger, to reduce the labor intensity of operator.
But the use of big bar cylinder, user is also required to correspondingly change more powerful creeling motor, and otherwise bar cylinder cannot be swapped out by exchanging mechanism.If bel-drivenn exchanging mechanism there is also the situation of belt creep, affect creeling efficiency.
It addition, in drawing frame work process, output sliver encloses after draft of drawing frame and is wound in output bars cylinder, when the full tube length that the length of cotton sliver in bar cylinder reaches to set is spent, control system makes drawing frame stop, and the most completely cylinder stops.Drawing frame with exchanging mechanism can go out a position before shifting bar cylinder onto drawing frame machine under the control of creeling instruction.But there is no the drawing frame that creeling is protected, there is following problem when creeling:
(1) when going out in the presence of there are people or thing in a position before drawing frame machine, if exchanging mechanism obtains creeling instruction, and at this moment bar cylinder is released out a position, just have the risk bumping against people or thing, also have and release the possibility that bar cylinder is tripped by object.If go out a position existence is other cylinders, also there is the possibility knocked over by other cylinders.
(2) the heaviest when going out an object of position existence before machine, the bar cylinder that exchanging mechanism is released withstands on and cannot continue on this object to move ahead, and also has the possibility that creeling motor rotation blockage causes damage.This situation is particularly likely to be present in the drawing frame of a diameter of Φ >=1000mm of output bars cylinder, and after full cylinder stops, full cylinder is released by exchanging mechanism, becomes full cylinder 1.If full cylinder 1 is not taken away by workman in time, next exchanging mechanism will push up full cylinder 1 when being released by full cylinder 2, for the bar cylinder of this diameter of phi >=1000mm, creeling motor promotes 2 simultaneously, it is likely that because power causes creeling motor rotation blockage even to damage not.
(3) double-head track, for convenience operative, machine the first two goes out all can be provided with between a position pedals step on foot-operated for workman.If foot-operated Rig up error or stretchable, Folding pedal are not packed up, cause foot-operated entering out a position, will interfere with going out a route.This situation just has to ride blocks the possibility that bar cylinder causes the damage of bar cylinder, exchanging mechanism component wear or creeling motor rotation blockage even to damage.
