Definitions
- the invention relates to a weaving machine according to the preamble of the main claim.
- An electrically controlled motor e.g. B. a stepper motor or AC / DC motor with appropriate control electronics or programming.
- the triggering contact pulse preferably comes from the camshaft of the weaving machine or else from a program and can be continuously adjusted in time.
- both the start-up and run-down time of the movement and the movement or standstill time can be preprogrammed (for example, in the case of stepper motors or electronically controlled motors, the so-called start-up times or braking ramps).
- the sheep machine can be moved back and forth without moving the sley. This is e.g. B. for taking out
- the dobby After switching off the automatic start by means of a contact pulse generator, the dobby can be rotated in the desired direction or position at the push of a button before the automatic movement of normal process described above continues.
- a planetary gear is proposed as a clutch gear, this planetary gear being provided with a freely rotating housing on which a servo motor acts.
- this housing is fixed via a disc brake or other locking elements (a self-locking worm gear, a hydraulic cylinder, a swivel drive or articulated lever with locking device) so that the camshaft drives the dobby machine directly.
- weft search the housing is released and is now driven by the servo motor, so that the shaft machine is driven by the servo motor and is not influenced by the camshaft of the weaving machine.
- the essential feature of the device according to the invention is that the time of transfer is programmable.
- the drive on the planetary gear housing takes place with each revolution (each shot) of the main shaft, the control preferably taking place in the resting phase of the eccentric, in order not to influence the transition time in this way.
- FIG. 1 shows the arrangement which has been customary to date
- FIG. 2 the arrangement according to the invention in a first exemplary embodiment
- FIG. 3 a second embodiment of the arrangement according to the invention.
- the mechanical dobby is connected to the main shaft of the weaving machine via a fixed coupling, so that a change in the change speed is not possible.
- 1 denotes a weaving machine, and 2 a mechanical dobby, which is driven by a motor 3, the speed of which can be regulated.
- the motor 3 is connected via a connection to a motor controller 4, which in turn is connected via a connection line 7 to a contact pulse generator 6, which is influenced by a pulse generator 5 of the weaving machine 1.
- the change in speed can be changed by the new device in that the dobby has its own motor instead of directly with the weaving machine. seem to be coupled. This achieves the advantages explained above.
- a cam shaft 90 of a weaving machine 10 can be seen.
- the mechanical dobby is designated with 20.
- a planetary gear 102 is connected into the camshaft 90, which is equipped with a revolving housing 100 which can be locked and fixed, for example, via a disk brake 101, an ⁇ instead of the disk brake 101 whose braking elements can be provided.
- a servo motor 30 acts on the housing 100, which is ineffective when the housing 100 is stationary, but drives the housing and thus the planetary gear 102 and thus the dobby 20 when the housing 100 is released.
- a hand crank instead of the servo motor 30, a hand crank, a hand lever arrangement or a hydraulic cylinder or swivel drive can be provided.
- the hand crank enables z. B. the manual adjustment of the shaft change time.
- the hydraulic cylinder serves z. B. for programmable, automatic adjustment of the shaft change time and for additional acceleration to shorten the shaft rotation time.
- weft search takes place when the weaving machine is at a standstill, the brake 101 is released and via the drive via the servomotor 30.
- the influencing of the time of change takes place with the weaving machine running, the brake released and additional drive via the servo motor 30. The same applies to the influencing of the shaft change shortening.
