Abstract
Abstract An improved device for controlling one or several processes or process steps as a function of a trigger pulse, comprising a continuously revolving shaft with a disk-shaped drive element, wherein the pulse causes a control disk to be coupled for a certain arc of the rotation, and wherein the said control disk is mounted on a shaft parallel to the drive shaft, wherein the improved device is adapted to provide with small forces and travels non-positive and non-slip connections with a drive mechanism for transmitting large forces. This device has a mechanical construction, operates reliably and is of simple design. Certain control functions are achieved either by dimensioning the angle of rotation or by a positive engagement.

Claim 1
Independent Claim
324 words
A device for controlling one or several working processes or steps as a function of a trigger pulse, comprising frame means, a shaft mounted in said frame means, a disc-shaped drive element mounted on said shaft, a driven element for controlling through a certain angle of rotation, a motor device mounted on said frame means for continuously driving said shaft in rotation, a control disc mounted axially movably and rotatable on said shaft on which said disc-shaped drive element is mounted, rings of claws arranged on said control disc and on said drive element and facing each other in the axial direction of said control disc and drive element, means associated with said control disc for axially displacing it and selectively effecting engagement of said rings of claws, a profile on the control disc, a stop member arranged on said frame means and having a section adapted to coact with said profile of said control disc as a function of its axial displacement in one direction, and which disengages when the axially movable said control disc is moved for engagement with said disc-shaped drive element, and which locks said control disc rotationally in its position in which it is out of engagement with said disc-shaped drive element, wherein the actuation of the dog clutches formed by said rings of claws control the duration of the coupling of said driven member to said drive element, a second shaft, a further disc on said second shaft, said second shaft being mounted freely rotatable parallel to said first shaft in said frame means, said further disc engages with its circumference the circumference of said control disc, said further disc has at least one further profile, engaging means, a driven mechanism, said at least one further profile controls through said engaging means the duration of the connection of said driven mechanism with said drive disc wherein said dog clutches are adapted to be controlled by said further profile.
Claim 2
Independent Claim
324 words
A device for controlling one or several working processes or steps as a function of a trigger pulse, comprising frame means, a shaft mounted in said frame means, a disc-shaped drive element mounted on said shaft, a driven element for controlling through a certain angle of rotation, a motor device mounted on said frame means for continuously driving said shaft in rotation, a control disc mounted axially movably and rotatable on said shaft on which said disc-shaped drive element is mounted, rings of claws arranged on said control disc and on said drive element and facing each other in the axial direction of said control disc and drive element, means associated with said control disc for axially displacing it and selectively effecting engagement of said rings of claws, a profile on the control disc, a stop member arranged on said frame means and having a section adapted to coact with said profile of said control disc as a function of its axial displacement in one direction, and which disengages when the axially movable said control disc is moved for engagement with said disc-shaped drive element, and which locks said control disc rotationally in its position in which it is out of engagement with said disc-shaped drive element, wherein the actuation of the dog clutches formed by said rings of claws control the duration of the coupling of said driven member to said drive element, a second shaft, a further disc on said second shaft, said second shaft being mounted freely rotatable parallel to said first shaft in said frame means, said further disc engages with its circumference the circumference of said control disc, said further disc has at least one further profile, engaging means, a driven mechanism, said at least one further profile controls through said engaging means the duration of the connection of said driven mechanism with said drive disc wherein said dog clutches are adapted to be controlled by said further profile.
Claim 3
Dependent Claim
86 words
A device as set forth in claim 1, wherein a pivot located on said frame means, an actuating device, and said means associated with said control disc comprises a pivoting lever pivotally mounted about said pivot on said frame means and connected at one end to said control disc and at its other end to said actuating device, wherein an actuation of said actuating device produces a selective axial movement of said control disc for engaging with said disc-shaped drive element and for releasing this engagement.
Claim 4
Dependent Claim
37 words
A device as set forth in claim 2, in which the actuating device comprises an operating magnet and a spring (23, 47) acting on the pivoting lever and anchored at its other end in said frame means.
Claim 5
Dependent Claim
77 words
A device as set forth in claim 3, wherein said disc-shaped drive element is a drive disc non-rotatably and axially non-displaceably located on said shaft, said second shaft carries both said driven element anD the non-rotatable and axially undisplaceable said further disc, a mating profile on said pivoting lever, and wherein said at least one further profile on said further disc is associated with said mating profile on said pivoting lever and acting as an engaging element.
Claim 6
Dependent Claim
29 words
A device as set forth in claim 4, in which the stop member (16) is mounted on the frame means adjustably about a circumference of the control disk (8).
Claim 7
Dependent Claim
91 words
A device as set forth in claim 4, in which the control disk has a hole-shaped profile (15) for the stop member in the form of a pin and the said further disk (25) has a corresponding hole (33) for a pin (32) mounted on the pivoting lever (14), wherein a coincidence between the said profiles (15) and (33) and the pins occurs after a certain preselected number of revolutions of the control disk in accordance with the transmission ratio between the control disk (8) and the said further disk (25).
Claim 8
Dependent Claim
