Definitions

  • the invention relates to a tangential belt drive for a plurality of similar, in at least one row next to each other working units of a machine for producing straight or twisted threads, in which the working units are divided into fields with at least approximately the same number of working units driven by an endless tangential belt , wherein at least one electric motor driving the associated tangential belt and deflection means for the tangential belt are assigned to each field.
  • Working units are to be understood in the following as machine elements at high speed, e.g. Spindles on spinning or twisting machines or rotors and opening rollers on OE spinning machines.
  • the work units of the machine are driven in groups by one of several endless tangential belts.
  • Each tangential belt can be driven by a motor.
  • the deflection pulleys of adjacent tangential belts are connected to one another in a rotationally fixed manner and thus bring about a frictional connection between adjacent tangential belts, by means of which the tangential belts and thus all working elements can run at least approximately synchronously or can be achieved in certain operating states. For example, when starting or stopping the machine, it may be necessary to shift energy between working elements or groups of working elements with different starting or stopping properties and thereby achieve at least approximate synchronous operation between the energy-giving and energy-absorbing working elements.
  • Such different start-up and run-down properties can be caused, for example, by groups of the same type of work units of different sizes or can also occur when at least approximate synchronization with different work elements is to take place, for example between the spindles of a ring spinning machine on the one hand and the stretching values on the other hand.
  • wrap angle with which the tangential belts wrap around their pulleys is 360 °, as can be seen from FIG. 1. Depending on the arrangement of the deflection elements, this sum of angles can be distributed differently to the individual deflection elements, but always remains 360 °.
  • tangential belt drive in which horizontal drive shafts run in the middle of the machine and are connected to angular drives (DE-B 1.141.571). These angular drives have superposed drive rollers over which tangential belts run. These in turn drive intermediate rollers, which each drive the corresponding drive elements of spindles via an individual, short, endless drive belt. This results in a large construction effort with considerable power loss.
  • the present invention has for its object to increase the frictional connection between the tangential belt on the one hand and the deflection rollers and the drive pulleys on the other hand and thus to improve the energy transmission both from the motor to the tangential belt and between the tangential belt.
  • This object is achieved in that it increases the sum of the deflection angle of a tangential belt beyond 360 °, that the increase in the sum of the deflection angle of a tangential belt by laying the drive rollers driving the tangential belt and / or by arranging further deflection roller elements and that the tangential belt corresponds to the Number of working units of each of the fields have a width between 7 and 15 mm and a thickness between 2 and 2.7 mm.
  • a particularly advantageous measure of the invention consists in non-rotatably connecting the deflection rollers respectively assigned to the tangential belts in the additional deflection roller elements, so that these additional deflection rollers not only increase the wrapping bends on the drive pulleys and the already existing deflection roller elements, but also additionally their own wrapping bends for the energy transfer between the tangential belts take effect.
  • the belt drive can be designed in a manner known per se as a flat or profile belt, for example a toothed belt, so that either non-positive or positive locking is possible.
  • FIG. 1 illustrates how the sum of the wrap angles of 360 ° of a tangential belt 1 according to the prior art is distributed over four deflection rollers 2, 3, 4 and 5 and a drive roller 6. It can be seen that the wrap angles on the deflection rollers 2 and 3 are only 45 ° and on the drive roller 6 are only 90 °, a total of 180 °. The distribution of these 180 ° on these rollers can be changed by moving the drive roller 6, but when the wrap angle on the drive roller 6 is increased, the wrap angle on the deflection rollers 2 and 3 is reversed. A small wrap angle on the deflection rollers 2 and 3 affects the frictional connection between the tangential belt 1 and the deflection rollers and thus the possibility of energy transfer to an adjacent tangential belt 7. A small wrap angle on the drive roller 6 reduces the frictional connection between this roller and the tangential belt 1 and thus the transmission of the drive energy to the tangential belt.
  • Fig. 2 illustrates how the wrap angle on the deflection rollers 2 and 3 and the drive roller can be increased significantly: the tangential belt 1 is deflected by laying the drive roller 6 in the opposite arc. Wrap angles on the deflection rollers 2 and 3 and the drive roller 6 of 165 ° and 150 ° are achieved.
  • the two adjacent tangential belts 1 and 7 are driven by the drive pulley 6 of a motor 8.
  • pinch roller pairs 10 ensure that the tangential belts 1 and 7 fit well against the whorls 11 of the work organs, not shown, spindles.
  • the two tangential belts 1, 7 are guided vertically offset relative to one another via deflecting rollers 3 and 18, which are coupled to one another in a rotationally fixed manner and form deflecting roller elements 14 and 15.
  • deflection roller elements 14 and 15 in addition to the deflection roller elements 14 and 15, further deflection roller elements 16 and 17 are provided against the longitudinal center of the machine.
  • the tangential belt 1 runs around the deflection roller element 14, around the drive pulley 6 and around the deflection roller element 15.
  • the tangential belt 7 runs around all four deflection roller elements 14, 16 and 17, 15, i.e. both deflection roller elements of each pair are wrapped in the tangential belt 7.
  • the looping of the frictional connection and the energy transfer between the tangential belts 1 and 7 causing deflection roller elements 14 and 15 is doubled from 90 ° (FIG. 1) to approximately 180 ° and thus the possibility of transferring energy is significantly increased.
  • Fig. 5 there is also the possibility, with a deflection roller arrangement as in Fig. 4, the motor 6 on the other side, i.e. to be arranged in the area of the tangential belt 7.
  • the tangential belt 1 wraps around the two deflection roller elements 14 and 15 with its inside and the deflection roller elements 16 and 17 with its outside.
  • the drive pulley 6 of the motor 8 is wrapped at an angle of around 180 °.
  • the tangential belt 7 only wraps around the two deflection roller elements 16 and 17, each with approximately 90 °.
  • the tangential belt 7 also wraps around the two deflection roller elements 16 and 17 with its outside.
  • the two deflection roller elements 14 and 16 or 15 and 17 are wrapped by both tangential belts 1 and 7 with arches each of more than 90 °, with a particularly tight frictional connection and thus the possibility of transferring a lot of energy between the tangles tialriemen 1 and 7 is given. Dabie can be easily achieved by appropriate arrangement of the additional deflection roller elements 16 and 17 that the sum of the wrap angles of both tangential belts 1 and 7 is the same size around all four deflection roller elements.
  • the deflection roller elements are arranged in such a way that the runs of the tangential belts 1, 7 running in the longitudinal direction of the machine are directed tangentially to the deflection rollers.
  • the drive motor 8 with the drive pulley 6 sits in the middle of the machine and is offset from the plane connecting the axes of the two deflection roller elements by an amount which corresponds to at least half the distance between the runs of the tangential belts 1, 7 running on both machine sides.
  • the deflection roller elements 16 and 17 are arranged between the two outer deflection roller elements 14 and 15 and the tangential belt 7 running between these deflection roller elements 14 and 15 with respect to the tangential connection plane between the deflection roller elements 14 and 15 by more than or at least deflect the diameter of the deflection rollers of these deflection roller elements.
  • the deflection roller elements 16, 17 deflect the belt path leading from the deflection rollers of the deflection roller elements 14 and 15 to the drive pulley 6 by approximately the deflection pulley diameter such that the belt running directions leading to and from the drive pulley are approximately parallel to one another run.
  • FIG. 6 shows a combination of the features of FIGS. 4 and 5.
  • the tangential belt 1 here runs analogously to the running direction according to the tangential belt 1 in FIG. 5; the tangential belt 7 runs analogously to the running direction of the tangential belt 7 in FIG. 4.
  • the respectively adjacent deflection roller elements 14 and 16 or 15 and 17 shown in FIGS. 4, 5 and 6 can in this case be mechanically coupled to one another.
  • This coupling can take place, for example, by meshing gears, which supports any energy shift that may become necessary.

Abstract

Une transmission à courroie tangentielle est utilisée avec une pluralité d'équipements similaires de travail d'une machine de production de fils tournés ou retordus. Les équipements de travail sont divisés en sections contenant un nombre au moins approximativement égal d'équipements de travail entraînés chacun par une courroie tangentielle (1, 7) reliée à un moteur électrique (8). Le nombre d'équipements de travail dans chaque section, compte tenu du rendement requis pour ce nombre d'équipements de travail et de l'allongement admissible de la courroie, est fixé de sorte que les courroies tangentielles aient une largeur et une épaisseur sensiblement inférieures à la normale. Les poulies de renvoi des courroies tangentielles de sections adjacentes sont en outre reliées entre elles de façon à résister aux torsions. Afin d'améliorer la synchronisation et la transmission de puissance dans et entre les sections, l'angle d'enroulement autour des poulies de renvoi et des poulies motrices est augmenté. Dans un premier mode de réalisation, cette augmentation est obtenue par un agencement spatial correspondant des poulies motrices par rapport aux poulies de renvoi (14, 15), et dans un deuxième mode de réalisation par l'utilisation d'un renvoi à courroie supplémentaire (21).
