Abstract
The process makes it possible to cut the yarn in the vicinity of the point where it leaves the twisting spindle, avoiding floating lengths of yarn and consequently cascade breaks. It involves bringing a blade with two cutting edges into the vicinity of the point where the yarn leaves, in such a way that this yarn is cut by the effect of the centrifugal force pulling it, and then in returning the blade to its position of rest. The blade 1 is actuated by means of an electromagnetic or, if appropriate, pneumatic device 2, 3, with the cooperation of a tracer and of electronic circuits.
Description
In some twist yarn process, particularly when the yarn of two-for-one twisting spindles is intertwined with the yarn feeding roller, must make the yarn must not be on cylinder.
For this reason, adopt suitable detector to come " detection " to receive near the yarn that occurs the cheese.When no yarn occurred, detector just made the operation of yarn cutting device input.
At present general the employing cut by routine by the Mechatronic Systems of sensor control and to be constituted, and its dependability is poor.
In fact, said apparatus all is designed to when the bobbin cradle debatching with moderate tension and injects yarn, and is used to cut the yarn of drawing from two-for-one twisting spindles, but usually their not yarn cuttings.In addition, because shearing device can not be fixed near the spindle, even if insert properly, but oversize because of the yarn that looses, the stepwise phenomenon that breaks end can take place in the yarn of contiguous spindle frequently.
The purpose of this invention is to provide a kind of technology and equipment to overcome above-mentioned shortcoming.
This technology is characterised in that, can adorn a blade at least near the yarn output, thereby by the centrifugal force that draws yarn it be cut off, and blade is return original position then.
The equipment of implementing this technology is characterised in that; a blade has two edges of a knife; can be in the arbitrary direction of rotation operation of spindle; the blade starting device is sent blade into cutting position; after cutting; blade is return original position, and blade is protected by backplate, and a sensor and electronic circuit are with the matched with devices work of above-mentioned starting blade.
Accompanying drawing is the optimum implementation of this equipment, and this equipment is applicable to the spindle of tep reel formula rotor and the spindle of band cup-shaped rotor.
Fig. 1 is used for the front view of the spindle of tep reel formula rotor for this equipment.
Fig. 2 is used for the axial II-II profile of Fig. 1 spindle for this equipment.
Fig. 3 is the top view of Fig. 1.
Fig. 4 is used to front view with the spindle of cup-shaped rotor for this equipment.
Fig. 5 is used for the axial V-V profile of Fig. 4 spindle for this equipment.
Fig. 6 is the top view of Fig. 4.
This equipment that is shown in Fig. 2 and 5 is made up of the electromagnet that soft iron core (2) and winding (3) constitute.
Have the edge of a knife 1 ' and the edge of a knife 1 " blade (1) for solid, its core can cut off yarn (7) in the either direction of spindle rotation.
When electric current is flowed through winding (3), iron core (2) enters coil under tension, and with twoport blade (1) propelling yarn cutting position, and at electric current not during flowing through coil, iron core (2) returns the original position in the middle of the backplate (4) under gravity or the effect of spring (not shown), its carriage (5) usefulness that fixes.
As shown in Figure 1 and Figure 4, this device places the position that cuts off near the yarn (7) of spindle output, has avoided the long yarn that looses, thereby has avoided the possibility of stepwise broken string.
Thereby the innovation part of this technology is the yarn that the applying centrifugal force tension is drawn from spindle, so that cut off by blade (1) outstanding on the yarn inner line of rail.
In addition, also be equipped with the monostable electronic circuit (not shown) that is independent of sensor (6) work, be used for blade moment is fixed on off-position.After the yarn cutting, blade returns rapidly in the suitable backplate (4).This has just been avoided the obstruction continued operation, also entail dangers to staff's on duty safety not.
Blade (1) reposition is the effect of gravity.
Also be equipped with in addition the device with monostable pneumatic circuit, it is independent of working sensor, is used for the blade instantaneous set in off-position, and then, blade returns the resting position by backplate (4) protection.
As shown in the figure, this equipment is very simple, but can guarantee reliability to greatest extent.
Constitute the shape of this equipment components,, can revise not exceeding under this patent protection domain situation.
