Technical field
The present invention relates to a kind of combing machine with at least one combing head, this combing head all has a nipper equipment in all cases, and this equipment links to each other with a drive source, and is mounted to and makes it center at least one rotation, to move back and forth.
Background technology
The function of combing machine nipper equipment and schematic diagram stem from document for example " short staple spinning: the 3rd: from the combing of Textile Institute, gait, flier ", the 22nd page to the 26th page.Nipper equipment moves back and forth on the detaching roller direction, and forms this oscillating movement by tongs plate axis.In this case, nipper equipment by the back turning arm in case the mode of reversing be fixed on the tongs plate axis.
In modern combing machine, have the nipper equipment of eight arrangements adjacent one another are so usually, and rely on a turning arm to be fixed on the tongs plate axis in all cases.The work synchronized with each other of nipper equipment.
This principle stems from CH-PS 471 910: for the nipper quality of balance vibration, can introduce a counterweight.Rely on this counterweight, can avoid increasing the imbalance that shows by the power of landing.
In the past few years, method for designing has progressively increased the number of nipper to greatest extent that combing machine can reach.This also makes the production capacity of combing machine be improved.
By increasing the nipper number, the whirling vibration of the tongs plate axis that is caused by driver has also increased inevitably.This situation need get involved the intrinsic frequency scope of drive system or tongs plate axis respectively.This has caused the moment of torsion that must be born by driving element and axle journal or the increase of torque peak.This is meaning again must adjust these circuit elements design schemes, to adapt to the superelevation load of generation.
As a result, just to adapting to the torque peak that in a special scope of nipper number, occurs, componentry ground increased in size.
Summary of the invention
Problem of the present invention is that the driver for combing machine nipper equipment proposes a kind of equipment, relies on this equipment can avoid these shortcomings.
Solve this problem by such motion: insert at least one during the driving between drive source and nipper equipment connects and be used for offsetting the device of intrinsic vibration.As a result, make the uphill process of torque smoothly and respectively reduce torque peak in nipper is counted scope, count in the scope, rely on the damping unit of " being also referred to as shock absorber or damper " to operate at this nipper.
Such damping unit is used for automobile engineering, for example (as in the clutch of driver element), wherein relate to part superelevation torque value, and the overlapping problem of the intrinsic frequency of vibration and element plays key effect.
Being used for driving element that nipper drives in combing machine, partly to use such damping unit be not new, yet, can not convert the application of automobile engineering from it easily, especially because torque ratio and actuation movement (reciprocating motion) in the combing machine are not identical with situation in the automobile engineering.
Further advantageously proposed: nipper equipment relies on a clutch to connect by tongs plate axis in all cases, wherein with tongs plate axis that drive source links to each other on fix a vibration damping device at least.This makes provides damping unit (being called for short " damper ") to become possibility in a simple designs, also can arrange a plurality of dampers on tongs plate axis thus, as desired in further dependent claims.
As further desired, this also is possible: at each combing head place, in the clutch zone, the device that will be used for vibration damping in all cases is fixed on tongs plate axis.
In this case, for example in the clutch zone, it is possible with the moving-mass of offsetting nipper equipment that a counterweight is installed, and damper is on this nipper equipment.
This damper can be positioned on the single counterweight of nipper equipment of each arrangement adjacent one another are.
The form of mixing also is possible certainly, and wherein damper can be positioned on the tongs plate axis on the one hand, and damper lays respectively at the clutch zone or is positioned on the counterweight on the other hand.
Having very big length because run through the tongs plate axis of the whole length of nipper equipment of arrangement adjacent one another are, consider the elastic torsion on the tongs plate axis length, is favourable if introduce driving force at the two ends of tongs plate axis.
Therefore being proposed in the driving shaft two ends all connects a drive source.
