Definitions

  • the invention relates to a drive device for the feed rollers on combing machines with several combing heads with tongs arranged pivotably about a fixed axis, on which the feed roller has its bearing, and with fixedly mounted drive means for the feed roller.
  • a gearwheel mounted coaxially with the feed roller rolls on a fixed toothed segment due to the oscillating movement of the lower pliers and transmits the rotary movement thus obtained to the feed roller via a freewheel.
  • Comb head parts to be arranged very significantly.
  • the large mass to be moved undesirably limits the speed.
  • REPLACEMENT BUTT (RULE 26 In another device, EP 360 064, the drive for the feed roller is controlled by an electric motor.
  • EP 360 064 it is proposed in EP 360 064 to arrange the electric motor on the pivot axis of a rocker arm for guiding the four-bar linkage.
  • the transmission of the drive movement is to be achieved by a toothed belt.
  • the pivot point of the rocker is in the effective range of the combing roller.
  • the drive motors must therefore be arranged between the combing rollers of each combing head.
  • Such drives are suitable for the previously relatively low number of combs, but they do not allow any further speed increases and optimizations of the motion sequences.
  • the object of the invention is to propose a drive device for the feed roller which is suitable for generating the drive movement at a central position in a freely selectable manner and for transferring it to the feed rollers on the moving elements of the combing heads in an unadulterated and adjustable manner.
  • the arrangement of the central drive shaft in the area of the pivot bearing of the tongs above the circular comb roller makes it possible to transmit a shock-free and jerk-free and centrally adjustable drive movement to the area of all combing heads and to feed it to the vibratingly mounted feed rollers there with simple means.
  • the stroke size can be adjusted either by changing the program of a drive element or by changing effective lever lengths on transmission elements.
  • the influences of the oscillating movement of the pliers apparatus can be taken into account when designing the drive program. Special correction gears can largely be dispensed with.
  • the invention contributes to a decisive improvement in the working conditions of the operating personnel.
  • the smooth running of the machine is significantly improved.
  • the design of the transmission elements from the drive shaft to the respective feed rollers according to claim 2 contributes to the further optimization of the drive device with regard to costs, speed of operation and smooth running.
  • the embodiment according to claim 6 shows a simple mechanical drive arrangement, which ensures high reliability especially in continuous operation and can be operated with the lowest energy consumption.
  • the drive according to claim 7 allows optimal coordination of the movements with other elements that are involved in the combing process.
  • the modification of the device according to the invention according to claim 8 ensures an optimization of the drive movement for the drive shaft.
  • the influences of the oscillating movement of the pliers apparatus on the law of movement of the drive shaft can be largely eliminated.
  • This combing machine has a circular comb roller 9, which rotates generally discontinuously, in the usual form.
  • the pliers apparatus 1 is mounted swinging under the head at a pivot point 12 arranged above.
  • the bearing 13 of the feed roller 2 is located on the lower tong arm 11.
  • the feed roller 2 forms, together with a feed trough on the lower tong arm 11, a clamping gap for the fleece to be delivered into the combing zone.
  • the feed roller 2 carries out a discontinuous delivery movement. After each combing process, which is supplemented by the fixed comb 7 and completed by the tear-off rollers 8, 8 ', it provides a new fiber beard for combing by the circular comb roller 9.
  • the time and the size of the delivery stroke of the feed roller movement must fit into the movement sequence of the work elements involved in the combing process in the most optimal form possible.
  • the transmission described below is provided for driving the feed roller 2.
  • a drive shaft 3 is provided which extends over several combing heads or over the entire length of the machine.
  • This drive shaft 3 is assigned a central drive, which according to FIG. 2 consists of a motor 4 with a corresponding drive control 41.
  • gear wheels 31 are provided on the drive shaft, which are connected to the drive shaft 3 in a rotationally rigid manner.
  • the oscillating movement of the toothed wheels 31 is transmitted to the drive wheel 21 of the feed roller 2 via toothed belts 23.
  • the drive program for the motor 4 is designed in such a way that it compensates for the additional movements caused by the oscillating movement of the pliers 1.
  • the drive control is designed so that it executes the predetermined program depending on the respective angle of rotation of the round comb shaft or an element moving synchronously with it.
  • the sensor 43 on the drive shaft 3 has control functions in cooperation with control programs within the controller 41.
  • the drive arrangement designed in this way has the advantage of a simple, low-mass and reliable construction.
  • the laws of motion of all elements can be coordinated very well. High combing lines are achievable.
  • a cam disk 32 can be arranged on the drive shaft 3 and the drive shaft 3 can be given a continuously or discontinuously rotating drive movement.
  • This rotating drive movement can be conventionally used e.g. by gears and toothed belts from the round comb shaft 9 to the drive shaft 3.
  • a synchronously controlled motor 4 ' was used for the drive.
  • the cams 32 have a movement program on their circumference, which allows an optimal movement of the feed roller 2 and eliminates the oscillating movement of the lower tong arm 11.
  • Each cam disk 32 is assigned a roller lever 34 which scans the cam disk 32 and transmits the oscillating movement to the feed roller via a free-wheel or a pawl arrangement 331, 22.
  • Either a ratchet gear 331, 22 known per se or a known freewheel with sprags (not shown) can be used as the freewheel.
  • Such freewheel or ratchet drives are generally known and therefore do not have to be described in detail.
  • a crank 51 which rotates synchronously with the round comb shaft 9 or another continuously rotating main shaft (not shown), issues a constant oscillating movement to a ratchet lever 53 on the drive shaft 3 via a coupling 52.
  • This oscillating movement is transmitted to the freewheel 54 of the drive shaft 3 via a freewheel or a corresponding ratchet gear.
  • the drive shown in FIG. 5 is a cam gear 6. This has a cam 62 rotating with the main shaft, the cam of which is removed by a roller lever 61. The oscillating movement is transmitted to the freewheel 64 via the pawl 63.

Abstract

L'objet de l'invention est un dispositif d'entraînement pour les cylindres d'alimentation de machines à peigner pourvues de plusieurs têtes à peigner, qui comprend un appareil à pince pivotant autour d'un axe fixe et des éléments fixes d'entraînement des cylindres d'alimentation, le palier du cylindre d'alimentation se trouvant sur l'appareil à pince. Afin de simplifier ce dispositif d'entraînement, de multiplier ses possibilités d'utilisation, de le rendre plus facile à manier et d'augmenter sa vitesse de travail, il est prévu qu'un seul arbre d'entraînement (3) coaxial par rapport au palier de pivotement de l'appareil à pince (1) serve à entraîner les cylindres d'alimentation (2) de toutes les têtes à peigner. Un entraînement (4, 5, 6) modifiable en fonction des lois de la dynamique est associé à l'arbre d'entraînement (3). Des éléments de transmission du mouvement de l'arbre d'entraînement (3) au cylindre d'alimentation (2) sont associés à l'arbre d'entraînement (3) dans la zone de chaque tête à peigner et l'appareil à pince (1) est monté librement rotatif avec sa manivelle (11) sur l'arbre d'entraînement (3).
