Abstract
Electromechanical control arrangement for controlling movement sequences in a textile machine, in particular for controlling the warp thread movement in a mechanical loom. The control arrangement includes a control cam, over the face of which a push member runs which effects the movement which is to be controlled; a continuously running drive shaft for the control cam; and a switching or control coupling, which is constructed as a spring coupling, connects the drive shaft and the control cam; and is switched via a magnet in conformity with the control pulses applied thereto, thereby controlling the rotation of the control cam.
Claims5
Electromechanical control means for controlling movement sequences in a textile machine, said control means comprising:
- a control cam having a control face;
- a push member which runs over said control face of said control cam, said push member effecting the movement sequence in the textile machine which is to be controlled;
- a drive shaft;
- a spring coupling for connecting said drive shaft to said control cam;
- and
- and electromagnet which is adapted to be energized by electrical control signals respectively for engaging and disengaging said spring coupling to be operative in conformity therewith, said control cam including a sleeve, and said spring coupling including a torsion spring which is disposed concentrically respectively in spring clutch relationship about said sleeve of said control cam and about said drive shaft;
- said torsion spring having two ends, one which is fixed to one of said control cam and said drive shaft, with the inner diameter of said torsion spring being smaller than the outer diameter of said one of said control cam and said drive shaft to which said one end is fixed;
- the other end of said torsion spring being adapted to be engaged and released by said electromagnet respectively for effecting said engagement and disengagement of said spring coupling.
