The means of dealing with problems:
The means that the present invention deals with problems are that height is alternately side by side near installing in the horizontal direction with two magnetizing coils, and it is right to constitute solenoid coil, paired solenoid coil group layering is laid, and line up 4 row columns; Its two ends crossbearer on framework as the support chip of fulcrum and from this support chip mid portion to the outstanding needle selection bar effect sheet of vertical direction, and eccentric and oppositely with the extrusion position of this needle selection bar effect sheet, by the outstanding pole piece of support chip, form the Trinity; In addition, at the front end of this pole piece, with the corresponding one by one respectively permanent magnet that is equipped with abreast of magnetic of above-mentioned paired solenoid coil.The select finger of fixed permanent magnet is contained in the framework, can swing flexibly and alternately upset.By means of the double solenoid coil needle selecting device that so constitutes, high speed that can obtain moving and high repeatable accuracy, the while can make the compact conformation of machine.
According to the present invention, the fulcrum of select finger is supported in the framework with minimum frictional resistance, makes it to freely swing.Because the needle selection bar application point of select finger is answered back to mutually with the desirable needle selection bar of the selector needle jack of intercalation in pattern drum, enter and be pressed into duty, or the centre of a plurality of bars by the selector needle jack, do not enter the multilayer of work and be 4 each magnetic that is listed as the paired solenoid coil group of columns and inhale mutually with a permanent magnet of each select finger, another permanent magnet is ostracised simultaneously, or does opposite action.
Below embodiments of the invention are described in detail with accompanying drawing.,, on the base plate (1) that the braiding machine suitable position is being fixed, keep certain intervals to erect side plate (2) (2) is installed to shown in Figure 5 as Fig. 1, set up a last top board (3) across the top of side plate (2), thereby constitute a frame structure.Two magnetizing coils (4) (4) height are in the horizontal direction fixed with screw alternately side by side near being installed on the substrate (5).Simultaneously, between paired alternately each magnetizing coil (4) (4) of height, be inclined cross and be fixed with a non magnetic plate (6).Its magnetic (7a) (7a) protrudes in a pair of solenoid (7) group on the non magnetic plate (6), is fixed at many levels on the substrate (5).In addition, another group solenoid coil (7) is screwed on substrate (8).Substrate (8) and aforesaid substrate (5) are vertically installed side by side, thereby make a plurality of magnetizing coils (4) ... line up 4 row columns, and be loaded on substrate (5) and the substrate (8) with different height, substrate (5) is fixing by base plate (1) and top board (3) respectively with the upper and lower of substrate (8).Extremely shown in Figure 7 as Fig. 5, two ends dwindle and constitute (9a) support chip (9) of fulcrum (9a) and outstanding to vertical direction by this support chip middle part, front end forms the needle selection bar effect sheet (10) of " mountain " font (10a), and it is eccentric and oppositely by the outstanding pole piece (11) of support chip (9), the three is integrated with the extrusion position of this needle selection bar effect sheet (10).In addition, the front end in this pole piece (11) (7a) is inhaled mutually with the magnetic (7a) of above-mentioned paired solenoid coil (7) or permanent magnet (12) (12) that a pair of polarity inequality is set in the lateral attitude constitutes select finger (13).On above-mentioned side plate (2), longitudinally equidistantly have many circular holes (2a) (2a), by with the fulcrum (9a) of select finger (13) (9a) easy and flexible ground insert corresponding circular hole (2a) (2a) in, thereby with side plate (2) (2) a plurality of select fingers (13) are supported neatly.And each select finger (13) is to be alternately upset of direction of principal axis with needle selection bar effect sheet (10), be supported on circular hole (2a) (2a) in.Therefore, permanent magnet (12) (12) on the select finger (13) will dispose like this: respectively be fastened on substrate (5) with screw on solenoid coil (7) magnetic (7a) and inhale mutually with the magnetic (7a) that screw is fastened on the solenoid coil (7) on the substrate (8), and in the permanent magnet (12) on each select finger (13) one, inhale mutually with the magnetic (7a) of the solenoid coil (7) of the oblique upper of paired configuration, and another permanent magnet (12) is then inhaled mutually with the oblique magnetic (7a) of the solenoid coil (7) of below.
The present invention as shown in Figure 8, the electric current that passes to different flow directions in the paired solenoid (7) (7) respectively comes excitatory, then the magnetic (7a) of a solenoid coil (7) becomes the N utmost point, and the magnetic (7a) of another solenoid coil (7) becomes the S utmost point.Therefore, a permanent magnet (12) of the select finger (13) close with the magnetic that becomes the N utmost point (7a) is attracted, and meanwhile, another permanent magnet (12) of the select finger (13) close with the magnetic that becomes the S utmost point (7a) then is ostracised, thereby select finger (13) is downward-sloping; On the contrary, as shown in Figure 8, the N utmost point and the S utmost point are replaced, and then select finger (13) becomes and is inclined upwardly.Therefore,, the desirable needle selection bar of selector needle jack is compressed into, played the needle selection effect with " mountain " font part (10a) of the needle selection bar effect sheet (10) on the select finger (13).And it is opposite, just inoperative.
In sum, come suction or repulsive force in addition for a select finger (13) by a pair of solenoid coil (7) (7), then the action of being adopted with aforesaid prior art by a polarization converter realizes supporting the actuating rod of select finger, the situation difference that makes it to freely swing, owing to allow two magnetizing coils (4) (4) work simultaneously, so so the multiplication of the magnetic flux density in the electromagnetic field is all corresponding multiplication of suction and repulsion.Therefore, the whole moment of solenoid coil (7) increases, so the action of select finger (13) is accelerated, has realized high speed.In addition, with respect to side plate (2) (2), the circular port (2a) that the fulcrum (9a) of select finger (13) (9a) is supported on side plate (2) with minimum frictional resistance (2a) in, so the action of select finger (13) is fluent, response is quick.Secondly, because select finger (13) itself is as executive component work, and solenoid coil group (7) lined up 4 layouts that are listed as columns, the two combines, then machine can design compact conformation.
