Abstract
The electro-magnetic driving apparatus 11 for controlling wefting in weaving machine comprises a releasing solenoid 14 for driving a moving workpiece 15 to a position for allowing releasing, and a stopping solenoid 13 for driving the moving work piece 15 to a position for stopping releasing. The number of winding coils of the releasing solenoid 14 is less than that of the stopping solenoid 13. Thus, comparing the releasing solenoid 14 with the stopping solenoid 13, the elimination of remaining current in the releasing solenoid 14 can be achieved faster. Therefore, for example, it is possible to accelerate a rise-up speed of a magnetizing current in the stopping solenoid 13 and further possible to increase the rise-up speed of the magnetizing current by means of a decrease of a mutual inductance.

Except above-mentioned advantage (1) and (2), present embodiment also provides following advantage:
(3) discharge the bobbin 14A axial length of solenoid less than the bobbin 13A axial length that stops coil 13, therefore, form with bobbin 14A wherein and to compare with the situation of bobbin 13A same structure, the axial length minimizing of electromagnetic actuator device 11, thereby reach size and reduce.
The 3rd embodiment
The 3rd embodiment realizes by changing the structure that discharges solenoid 14 among second embodiment.In other words, it has and the first embodiment identical construction.Therefore, all use identical label to represent with those identical among second embodiment elements, and will omit the explanation of these elements.
In the electromagnetic actuator device shown in Fig. 2 B 11, the coil turn setting that discharges solenoid 14 is also lacked than the coil turn among second embodiment.That is to say that in this embodiment, release coil width R2 is less than prevention coil width R1, and release coil height L2 is less than stoping coil height L1.Winding wire footpath d2 sets and equals winding wire footpath d1.
Present embodiment provides and above-mentioned advantage (1), (2), the advantage identical with (3).
The invention is not restricted to the foregoing description; For example, also can carry out following change.
In first to the 3rd embodiment, release coil winding district A2 can set greater than stoping coil windings district A1, is less than the coil turn that stops solenoid 13 as long as discharge the coil turn setting of solenoid 14.In addition, for example, release coil width R2 can be greater than stoping coil width R1, and release coil height L2 is greater than stoping coil height L1.
All set less than the coil turn that stops solenoid although in the various embodiments described above, discharge the coil turn of solenoid, also can set the coil turn that stops solenoid less than the coil turn that discharges solenoid for.In this case, can set the coil resistance that is lower than the release solenoid to the coil resistance that stops solenoid.In addition, be less than the coil turn that discharges solenoid, can reduce by two mutual inductances between the solenoid by the coil turn that stops solenoid is set.As a result, can make the aftercurrent (residual magnetism) that stops solenoid that the influence that discharges solenoid is reduced to minimum, therefore can further increase the climbing that discharges solenoid disappearance electric current.
Discharging solenoid also can be different mutually with the winding wire footpath that stops solenoid.By winding wire is directly made mutual difference, can for example under the identical situation of the coil turn of two solenoids, make the coil resistance of solenoid become different mutually.Compare with the coil windings with less line footpath, the coil windings with big winding wire footpath demonstrates the lower coil resistance of per unit length.In addition, discharging under the solenoid situation different mutually with the winding wire footpath that stops solenoid, discharging solenoid can be different mutually with the coil turn that stops solenoid.In this case, can for example make bobbin that discharges solenoid and the bobbin that stops solenoid have same structure.That is to say, can be with identical bobbin to two kinds of solenoids.
Also can form release solenoid and stop solenoid with different resistance values.In this configuration, even when the coil turn of for example two solenoids is identical, also can make their coil resistances separately different mutually.When discharging solenoid and stop solenoid to be made with the material with different resistance values, coil turn separately can equate with the footpath of winding wire separately or be different mutually.
It is round-shaped that the section shape (along the shape of cross section of being done perpendicular to the coil windings length direction) of release solenoid and prevention solenoid coil windings is not limited to.No matter section shape how, the coil resistance of per unit length all is lower than the coil resistance that has in the small cross sectional coil windings in having the coil windings of comparatively large cross-sectional area.That is to say, different mutually by the section shape that makes two solenoid coil windings in the present invention, also can make the coil resistance of per unit length different mutually.
Also can set the coil resistance that stops solenoid and be lower than the coil resistance that discharges solenoid.In this case, compare, can accelerate the disappearance of aftercurrent in stoping solenoid with discharging solenoid.
