Definitions

  • the invention relates to a shaft drive for at least a weave of a loom.
  • Such a dobby is for example from the DE 697 02 039 T2 known.
  • the between the eccentric and the driving shaft arranged latch switching mechanism is here for each shaft movement, i. for an upward movement of the shaft or for a downward movement of the shaft respectively switched on for half a shaft rotation.
  • Such Dobby machines are very flexible. However, such Dobby machines the working speed of eccentric machines do not reach.
  • the work of the pawl switching mechanisms is susceptible to wear. An increase in the working speed does not only lead to ratchet wear, but also to strand and shank breaks.
  • the shaft movement is now determined that neither a pure sinusoidally oscillating up and down Movement of the shaft still a swinging up and down movement with downtimes in the upper and lower reversal point is obtained. Rather, the drive does not enforce only during the movement phases, but now also during the resting phases of the shaft in which the shaft otherwise usually in the upper or lower reversal point rest, a continued movement of the same.
  • This measure opens up the possibility of maximum acceleration of the Shank to reduce.
  • the avoidance of acceleration jumps leads to a smooth running of the shafts, the even at high working speeds to no excessive Vibrational excitations.The limit for the working speed, occur in the shaft fractures and strand breaks, can thus very far to higher working speeds be moved.
  • the corresponding, from the shaft to be traversed motion curves, according to a first Embodiment of the invention, by means of freely programmable Drives are achieved, which move the shaft.
  • a the Drives assigned control device calls the drives during the movement phases a high speed off to the shaft as quickly as possible from the one reversing position into another reversal position. This process is for shedding necessary to warp threads from the warp thread level move up or down. approaches the shaft of its intended reversal position slows down the control device the output of the shaft drive, the e.g. formed by connecting rods, and leaves him then commute to the same when reaching the reverse position. ever after residence in the reverse position, the pendulum oscillation go through one or more maxima and minima (wave trains).
  • the pendulum movement in the resting phases has the advantage that the Shaft drive can specify shaft movements, the lower Have acceleration values.
  • the Shaft movement in the course of time in the transition from one Reversal into the other of a harmonic function (sinus or cosinus) and, in the reverse position, enters a time function over, at the beginning of which the acceleration is the same Value has the same as when leaving the curve branch of the transition movement.
  • the acceleration curve is thus continuous.
  • the movement curves also called "laws of motion" be
  • the movement curves for the transition of the shaft from a reversal position in the other, as well as for commuting within the reversal areas can in a simple embodiment in one Data storage to be stored.
  • the controller calls then the respective cams from the data memory on and controls the one or more motors of the shaft drive accordingly at.
  • the cams can also advance or be calculated in real time, with the calculation case by case depending on the respective given boundary conditions according to special Optimization criteria can be done.
  • optimization criteria For example, be that a minimum opening time must not be fallen below, that the maximum accelerations are to limit that acceleration jumps inadmissible are that the shaft speed is to be limited or that given a maximum acceleration a maximum operating speed is calculated.
  • the curves resulting from these optimization criteria can then be cached and for driving the shaft drive be applied.
  • the pendulum movement of the shaft in the upper and lower turning point area has the other Advantage that by the pendulum movement of the Webschaft the Warp threads can be somewhat relaxed, causing the weft stop can facilitate.
  • the shaft via a Coupling device optionally connected to a first drive be a constant between the two reversals oscillating motion generated, or with another drive, the pendulum about the upper or the lower reversal position Movement generated.
  • the switching is preferably carried out during existing synchronization phases.
  • the corresponding coupling can be a linear motion transmitting clutch.
  • the shaft drive according to the invention can according to another Embodiment one with a rotary drive device connected input shaft, which ultimately serves to drive a gear assembly, the back and forth generated by the weaving movement.
  • the between the Input shaft and the gear assembly provided clutch assembly has at least two input elements and a Output element connected to the gear assembly is.
  • the input elements generate at tapping the movement from the inside at least temporarily a synchronous movement.
  • the clutch assembly from one input element to the other input element switch.
  • the switching is thus neither as a jerk nor noticeable as a shock in the drive train. Reducing the Rotational speed of the input shaft is therefore to switch not necessary. It can be done without accepting excessive Wear or shaft or strand breaks a Achieve increased working speed of the loom and even if individual healds are always activated and must be disabled.
  • the shaft drive that is first input element is a clutch disc that is fixed with the input shaft is connected and thus one of the rotary drive device predetermined uniform rotational movement performs.
  • the second input element is then a clutch disc, which performs a rotary oscillation movement.
  • the rotational oscillation movement is in selected angular ranges, the upper and lower reversal points of the weave correspond, respectively briefly or completely in synchronism with the rotational movement of the first input element. This is regardless of whether it is the rotational movement or the up and down movement to harmonic or non-harmonic Moves.
  • the second input element back to after a rotation the first input element by 180 ° turn over a certain angular range in synchronism with the first input element mitzusted.
  • the oscillating motion of the second input element can be achieved by a cam drive that is rigid with the input shaft is connected.

Switching the cam follower from the tap of the one cam the other cam takes place in a rotational position of the Cams in which their arcs coincide, so that the here from the one cam tapped movement synchronous to the tapped from the other cam Movement is.
  • One of the two cam discs can be designed in this way be that they have the necessary training for movement generated while the other cam disk as a reversing disk is formed and the oscillating reversal position movement generated. As such, it only has each to take over the cam follower element serving short synchronous arcs and otherwise a profile on the webshaft no shiftworking movement but only the reversal vibration generated. In the simplest case, she is one Disc with double circumferential vibration and less radial stroke. It can also be two or more cams with different working profiles are provided.
