Definitions

  • the invention relates to a switching drive for at least one heald of a loom.
  • a plurality of healds are generally provided on looms, each having a plurality of mutually parallel strands are guided by the thread eyes the warp thread.
  • the healds are moved up and down very quickly.
  • Serve shaft drives which are referred to as dobby or eccentric machines. So-called eccentric machines generate from the rotating movement of a drive shaft the up and down movement of the weaves, whereby high weaving speeds can be achieved.
  • eccentric machines are inflexible. The creation of patterns or different bindings is limited. Therefore, shaft drives are widely used, in which a pawl clutch is provided between a drive shaft and the eccentric for generating the shaft movement.
  • Such a dobby is for example from the DE 697 02 039 T2 known.
  • the pawl shifting mechanism disposed between the eccentric and the driving shaft is here switched on for each shaft movement, ie for an upward movement of the shaft or for a downward movement of the shaft in each case for half a shaft rotation.
  • Such dobby are very flexible.
  • Such dobby machines can not reach the working speed of eccentric machines.
  • the work of the pawl switching mechanisms is susceptible to wear. An increase in the operating speed, however, not only leads to ratchet wear, but also to strand and shank breaks.
  • the movement to be performed by the shaft during the rest phase is generated or predetermined mechanically.
  • the shaft is over a Coupling device optionally connected to a first drive which generates a constantly oscillating between two reversing positions movement, or with another drive which generates the oscillating about the upper or lower reversal position movement. Switching takes place during existing synchronization phases.
  • the shaft drive according to the invention has an input shaft connected to a rotary drive device, which ultimately serves to drive a gear arrangement which generates the reciprocating movement of the heald shaft.
  • the clutch assembly provided between the input shaft and the transmission assembly has at least two input members and an output member connected to the transmission assembly.
  • the input elements generate at least temporarily a synchronous movement when tapping the movement from the inside.
  • the clutch arrangement can switch from one input element to the other input element. The changeover is thus not noticeable as a jolt nor as a shock in the drive train. Reducing the rotational speed of the input shaft is therefore not necessary for switching. It can be achieved without accepting excessive wear or shaft or strand breaks increased operating speed of the loom and even if individually Web shafts must be repeatedly activated and deactivated.
  • the first input element is a clutch disc that is fixed with the input shaft is connected and thus performs a predetermined by the rotary drive means uniform rotational movement.
  • the second input element is then a clutch disc that performs a rotational oscillation movement.
  • the rotational oscillatory movement is in each case for a short time completely or nearly synchronously with the rotational movement of the first input element in selected angular ranges which correspond to the upper and lower reversal points of the heald.
  • the second input element then rotates back to run in synchronism with the first input element over a certain angular range after a rotation of the first input element through 180 ° again.
  • the oscillating motion of the second input member may be achieved by a cam gear rigidly connected to the input shaft.
  • a cam drive is used whose shaft is running at twice the input shaft speed, so that both the short synchronous movement for the upper reversal point and the short synchronous movement for the lower reversal point can be generated with a single cam.
  • the oscillating motion can be generated by electrical, hydraulic or pneumatic drives.
  • a rotating with the output member pawl is used, which is operated via at least one, preferably two shifter, where it passes.
  • the shifters can be directly electrically or pneumatically confirmed. However, it is preferred to drive them via a control clutch from a cam drive ago.
  • the control clutch can then be operated with very low power, on the other hand, sufficiently large forces are generated to move the shift lever.
  • the clutch can e.g. Be controlled by stationary control magnets and be formed by a swinging driven selection finger. This results in a precisely responsive and with low energy controllable control arrangement for the clutch assembly.
  • the two input elements of the clutch assembly are formed by cams, both of which rotate synchronously with the input shaft and are driven by this.
  • the starting element the coupling arrangement forms a cam follower, which can alternatively be brought into engagement with one or the other cam disk.
  • the cam follower generates a swinging motion and thus is not only part of the clutch assembly but also part of a gear assembly for generating the reciprocating motion from the rotational movement of the input shaft.
  • the switching of the cam follower from the tap of the one cam to the other cam takes place in a rotational position of the cam in which their arcs match, so that the tapped here of the one cam is synchronous with the movement tapped by the other cam disc movement.
  • One of the two cams may be configured to generate the motion required for shedding while the other is constructed as a reversing shim and to generate the oscillating reverse position movement. As such, it only has short synchronizing arches respectively serving to take over the cam follower element and otherwise a profile which does not generate a shedding motion on the weaving sheave but only the reversing position oscillation. In the simplest case, it is a disc with double circumference and lower radial stroke. It is also possible to provide two or more cams with different working profiles. In each case reversing ply disks can be arranged between these cams, which produce the oscillating reversing position movement on the cam follower.
  • each cam set with its cam follower and to couple the cam followers optionally with an output shaft.
  • the cams then form the input elements of the corresponding cam followers, while the output member of the coupling assembly is connected to a linkage which actuates the heald.
  • FIG. 1 a heald 1 with associated shaft drive 2 is illustrated.
  • the heald 1 is formed by a provided with strands 95 frame, which is in operation as indicated by an arrow 3 moves up and down.
  • a linkage 4 which attaches to the weaving shank 1 at two or more points 5, 6 and forms the output of the shaft drive 2.
  • the shaft drive 2 includes one or more drive sources, for example in the form of the motors M1, M2. These are, for example, electric servomotors, which are the linkage 4 via a screw jack, a belt transmission or other, the rotational movement of the motors in a linear motion converting gear are connected. Alternatively, linear motors, linear stepping motors or the like can be used. It suffices in some cases, a single engine, while in other two or more engines required are.
  • the motors M1, M2 are controlled by a control device C, for example based on a microcontroller, which is connected to a memory unit M.
  • the control device C controls the motors M1, M2 in such a way that the heald 1 is moved up and down in accordance with the shed formation. This can be done, for example, by means of two or more curves K1, K2 stored in the memory unit M, wherein the first curve K1 specifies the movement of the heald 1 between its reversal positions, while the curve K2 specifies a movement of the heald 1 in its reversal positions.
  • the movement of the weave shaft 1 is as follows:
  • FIG. 3 is the shaft movement based on the in the direction of arrow 3 in FIG. 1 designated X coordinate of the heald 1 plotted against the time t.
  • the course of the movement is indicated by a curve I, eg the shaft movement can follow a sine function.
  • the curve I of the movement passes into a vibratory motion of reduced amplitude and reduced acceleration. This marks a curve branch II.
  • the peculiarity of this Kurvenasts is that this in angular ranges of eg ⁇ 15 ° to the upper reversal point TO, the in FIG. 3 indicated sinusoidal oscillation without technically relevant deviation follows.
  • the particular characteristic of the movement impressed on the motors M1, M2 by the control device C is thus that the heald 1 does not rest in the upper reversal point TO but executes a vibration in a reversal point area BTO.
  • the effect of this measure can be seen from the dashed curve III plotted in the same diagram, which illustrates the downward acceleration of the heald 1, which is therefore plotted with negative signs. If the movement of the heald shaft 1 initially follows a sine movement, the shaft acceleration is also a sine function. In the region of the upper vertex, when the upper reversal point TO is reached, the control device C now changes from the curve I to the curve II (FIG. FIG. 2 ).
  • FIG. 3 To illustrate the benefits of Umlopeddlingschwingung in the upper or corresponding at the lower reversal point is on FIG. 3 referenced in which a dot-dash curve branch IV connects the upper vertices of the shaft movement together. If the heald shaft 1 would follow this curve IV after reaching its upper reversal point TO, the acceleration which just has the value A1 would suddenly fall to the value 0 at the time T1. The resulting acceleration peak generated on the weaving shank 1 and the strands and on all associated transmission parts loads that can lead to shaft and strand breaks. Such loads are minimized or largely limited by the pendulum movements, because by the same accelerations are kept to a minimum.
  • FIG. 4 illustrates that reversal point oscillation can be sustained over several cycles.
  • the rest phase R occurring between the first and the last vertex may extend over one, two or more cycles of the basic oscillation of the shaft movement represented by dashed lines.
  • fundamental vibration is meant the harmonic function, with which the heald 1 is transferred from its lower reversal point TU to its upper reversal point TO. The latter takes place during its movement phases B.
  • FIG. 12 illustrates a modified realization of the above-illustrated idea of imparting low amplitude motion to the heald 1 during its resting phase R, the movement remaining in the upper turning point range BTO or, correspondingly, in a lower turning point range.
  • the vertexes of the prime 1 of the heald 1 illustrated in dashed lines which serves to transfer from one reversal point to the other, are marked by a curve branch V whose second time derivative has the same acceleration value at times t1, t2 marking the vertices of the fundamental like the fundamental.
  • the acceleration of the heald 1 is stepless or continuous, as the Kurvenast VI illustrates. However, it will curve according to FIG. 3 or 4 preferred because of the web technical advantages associated with them.
  • the said movements of the heald shaft 1 in the movement phases B and the resting phases R can also be achieved with a mechanical shaft drive 2, as described in US Pat FIGS. 6 to 10 is illustrated.
