Definitions

  • the invention relates to a tangential belt drive for a plurality of similar, in at least one row side by side working units of a machine for producing twisted or twisted threads, in which the working units are divided into fields with at least approximately the same number of working units each driven by an endless tangential belt, whereby at least one electric motor driving the associated tangential belt and deflection means for the tangential belt are assigned to each field.
  • Tangential belts of the type mentioned at the outset are used, for example, in ring spinning machines, ring twisting machines, open-end rotor spinning machines or open-end friction spinning machines or the like.
  • the working units such as spindles, rotors or opening rollers or the like are arranged next to one another in one or two rows and driven by tangential belts which run against the whorls of the working units. It is common practice to drive the tangential belt in the area of one of the front ends of the machine and to deflect it in the area of the other front end. As a result of the wrapping around the whorls and the necessary pressure rollers, the large number of work units causes considerable energy consumption and belt wear due to flexing work.
  • a tangential belt drive is also known (DE-AS 1141571), in which the work units arranged in rows next to one another are divided into fields which have at least approximately the same number of work units, each of which is driven by an endless tangential belt. An electric motor and deflection elements are assigned to each of these tangential belts in a field. With this design, the tangential belt drives intermediate rollers, which in turn drive the work units via endless straps. This design of a tangential belt drive has not found its way into practice.
  • the invention has for its object to provide a tangential belt drive of the type mentioned, in which power losses and / or belt loads can be reduced.
  • the tangential belts (10, 11, 10 ', 11', 10 ", 11", 33, 37) have a width between 7 mm and 15 mm and a thickness of 2 mm to 2.7 mm , and that the number of work units (4) per field is determined taking into account the drive power that can be transmitted by the tangential belt with a permissible belt stretch.
  • the contact elongation of the individual tangential belts is limited to 0.6% to 1.5%. It has been shown that the belt stress can be kept low by this measure, while in addition the tolerances resulting from belt expansions with respect to the rotational speeds of the individual work units keep within tolerable limits.
  • the tangential belts of adjacent fields are guided over at least one common deflection roller element, the deflection rollers of which are coupled or can be coupled in a rotationally fixed manner. This will allow some synchronization of speeds between the receive individual fields, which is particularly advantageous when the drive is switched off or fails due to a power failure, since then all working units run largely evenly.
  • the deflecting roller elements are each arranged between two adjacent working units. This measure ensures that no space in the spindle division is lost. In order to avoid transmission losses, it is further provided that the tangential belts run directly against whorls of the working units.
  • the fields are delimited by four deflection rollers in a two-row arrangement of the work units and that the associated electric motors are arranged in the middle between the two rows.
  • the diameter of the deflecting rollers can be dimensioned such that they can be arranged between adjacent work units without changing the machine division.
  • deflection roller elements are used, each consisting of two deflection rollers arranged one above the other in the axial direction, on which the tangential belts of the adjacent fields, which run correspondingly offset in height, are deflected.
  • the whorls of the working units are arranged on the side of the tangential belt facing away from the longitudinal center of the field and the deflection roller elements are arranged on the side of the tangential belt facing the longitudinal center. This ensures that good spatial utilization is obtained and that no additional burdens are also expected of the work units.
  • the machine designated overall by 1, has two parallel rows 2 and 3, working units 4 of the same type which are driven at the same speed and of the same type.
  • These working units 4 can be spindles, for example, with FIG. 1 then being able to be understood as a plan view of the spindle area of a ring spinning machine.
  • each spindle 14 is mounted in a spindle bearing 5, which is fastened with the aid of a nut 6 to a spindle bench 7, which in each case leads along the relevant machine side.
  • Each spindle 14 has a whorl 8, on which it is driven by a tangential belt 10 or 11.
  • Pressure roller hangers 12 of the same design serve to apply the tangential belts 10, 11 against the whorls 8.
  • Fig. 1 the whorls 8 of a first group of twelve working units 4 of each row 2 and 3 are driven by a first, endless tangential belt 10 and each further group of twelve working units 4 of both rows 2 and 3 are each driven by further tangential belts 11 and so on.
  • the tangential belt 10 is guided through deflection rollers 14, 15, 16 and 17 and loops around the drive roller 18 of an electric motor 19.
  • the tangential belt 11 is guided and looped through deflection rollers 20 and 21 coaxial to the deflection rollers 15, 16 and two further deflection rollers that are no longer visible the drive roller 22 of an electric motor 23.
  • adjacent tangential belts are each offset in height from one another.
  • each tangential belt drives between 80 and 150 spindles depending on the energy requirement of a spindle, so that between 12 and 7 tangential belts can be arranged in a ring spinning machine with, for example, 1,000 spindles.
  • the deflection rollers of mutually adjacent tangential belts are also connected to one another in a rotationally fixed manner and form a deflection roller element.
  • Fig. 4 shows that the pulleys 15 and 20 are attached to a common shaft 24. The same applies to the deflection rollers 16 and 21.
  • the shafts 24 of the deflection rollers are rotatably mounted in bearings 25 which are connected to the spindle bench 7 by nuts 26.
  • Fig. 2 shows a machine 1 'with only one row 2 of work units 4. This can be the spindles of a one-sided spinning machine or to drive the rotors on one side of an open-end spinning machine.
  • a first group of twelve work units 4 of the single row 2 is driven by a first tangential belt 10 ', a second group of twelve work units 4 by a second tangential belt 11'.
  • Additional tangential belts can drive other groups of work units.
  • the tangential belts can be driven by electric motors 19, 23, on each shaft of which a drive roller 18 or 22 is seated, which is wrapped by the relevant tangential belt 10 'or 11'.
  • Each tangential belt 10 ', 11' runs over three deflection rollers 26, 27 28 and 29, 30 (the third is no longer visible), here too the deflection rollers 27 and 29 arranged one above the other are rotatably connected to one another and a two adjacent tangential belt 10 ' and 11 'form a common deflecting roller element.
  • the machine 1 "of the third exemplary embodiment shown in FIG. 3 again has two rows 2 and 3 of work units 4. However, only groups of twelve work units 4 of each row are driven individually by a tangential belt 10" or 11 ", In this respect, this embodiment corresponds to a doubling of the embodiment of Figure 2. The drive of the two rows of work units is therefore independent of one another.
  • a number of work units can, for example, stand while the other is running - this happens if the work units are the spindles of a ring spinning machine with independently driven sides. E.g. However, a number of work units can also be driven at a different speed than the other - this occurs, for example, if the work units in one row are rotors and the other row are opening rollers of an open-end spinning machine.
  • the motor 19 drives here via its drive pulley 18 the tangential belt 10 "which drives a group of work units 4 of the row 2 and which is guided over the deflection rollers 26, 27, 28.
  • a second motor 23 drives the next tangential belt 11" via its drive pulley 22, the guide roller, not shown, corresponding to the guide roller 27 of the first tangential belt 10 ′′ and the guide roller 30, which is underneath the guide roller 27 and connected to it in a rotationally fixed manner, and the guide roller 30. Further tangential belts are arranged and guided accordingly.
  • Row 3 of the working units shows the end of such a row: a last drive motor 31 drives, via its drive pulley 32, the last tangential belt 33 of this row, which is also guided over three deflection rollers 34, 35, 36.
  • the deflection roller 34 is again part of a deflection roller element which is common to the tangential belt 33 and the tangential belt 37 adjacent to it.
  • the tangential belts can be chosen to be much thinner and narrower than a single tangential belt that drives all work units of a machine or all work units of a series.
  • the tangential belt can have a width between 7 and 14 mm and a thickness between 2 and 2.7 mm. This results in a cross section of 14 to 38 mm 2 or a reduction in the cross section to 15-30% of the belt previously used.
  • the contact elongation measured when the machine is at a standstill should be as low as possible and be between 0.6 and 1.5%.
  • the tangential belt can be made from polyamide, polyester or from mixtures based on polyamide or polyester, as are known, for example, under the trade names «Kevlar - or « Aramid Erasmus For example, the tangential belt. Polyester, this results in a contact elongation of 1 to 1.5%. With a mixture of the aforementioned type, there is an elongation of contact between 0.3 and 1%.
  • FIGS. 6 and 7 at least one further, similar tangential belt 10 a or 11 a can be accommodated along the course of a tangential belt for reserve in the machine, preferably in the spindle bank 7.
  • this reserve belt can be surrounded by a plastic sheath 38 and arranged in a holder 36, which is fastened within the spindle bench 7. If there is damage to the tangential belt, the tangential belt can be removed from the plastic cover and placed on it without great delay.
  • this holder 39 can be arranged once above (FIG. 7) once below (FIG. 6) the tensioning roller suspension 12.
  • Electric motors that drive tangential belts that have common deflection elements and therefore run synchronously have a common power supply are three-phase motors which are supplied with three-phase current from the speed control device via a line.
  • all belt drive motors 19, 23 ... of the spinning machine are connected in parallel to a line 40, which is connected to the network 42 via a control device 41.
  • the control device 41 allows all connected motors to be switched on and off together. In addition, it can also have means for changing the speed of the motors, for example by changing the feed frequency.

Abstract

Commande à courroie tangentielle pour une pluralité d'unités de travail similaires (4), disposées sur au moins une ligne l'une à côté de l'autre, et cela dans une machine (1) pour la production de fil retordu. Le long de cette commande à courroie (10, 11) les unités de travail sont disposées en groupes ayant à peu près le même nombre d'unités (4), pour chaque groupe il est prévu au moins un moteur électrique (19, 23) et des moyens de guidage (14, 17, 20, 21) agissant sur les courroies (10, 11). Pour diminuer les pertes d'énergie d'une telle commande, il est prévu de diminuer sensiblement aussi bien la largeur que l'épaisseur de la courroie tangentielle (10, 11), en particulier en choisissant sa largeur entre 7 et 14 mm et son épaisseur entre 2 et 2,7 mm. Cela est possible par le fait que le nombre d'unités de travail (4) d'un groupe est choisi de manière à être en rapport avec la puissance absorbée et avec l'allongement admissible de la courroie. Dans un développement ultérieur de l'invention, il est prévu que les courroies tangentielles (10, 11) des groupes d'unités voisines soient guidées par des poulies (15, 16, 20, 21) couplées ensemble de façon rigide.
