Definitions
- the invention relates to a drafting system for spinning machines with lower rollers of great length, which undergo torsion during operation, with a brake which prevents the torsion after stopping the lower rollers relaxation.
- the invention of the document pursues the aim of having the outlet of drafting systems
- the invention was therefore the task of preventing the relaxation of the torsion built up during operation when stopping the machine in all longitudinal areas of the drafting system. It solves this problem by having at least one of the lower rollers, Preferably, the one with the highest built in operation torsion equips with several, arranged in approximately the same distance spaced brakes.
- Figure 1 is a plan view of a drafting system with three lower rollers of great length.
- Figure 2 is a view of a brake from the side.
- the output roller 4 of the drafting system 1 is driven by a motor 5 only assigned to it.
- the center roller 3 also has its own motor 6. With this center roller, the input roller 2 is connected via a gear 7, in the changing, the pre-distortion between the center roller 3 and the input roller 2 causing reduction ratios are adjustable.
- the middle sub-roller 2 usually moves over them strained Unterriemchen, which are guided over fixed Unlenkbügel and Riemchenhanfige. Their drive requires considerable momentum, which causes particularly high torsion in the middle bottom roller during operation and in comparison with the other bottom rollers.
- the center sub-roller 3 is equipped with a plurality of brakes 8 distributed in the illustration with three, in approximately the same mutual distance in the beginning, middle and end along this roller.
- These brakes 8 are designed as holding brakes, that is, they do not serve to decelerate the roller, but to hold the (almost) come to a standstill roller and prevent further rotation.
- the brakes are therefore designed as two, the lower roller comprehensive brake shoes 9 on two-armed levers 10. At the other ends of the lever arms engages a working element 11, which allows the brake shoes to press against each other.
- the brake shoes 9 are designed so flat that they can be arranged between two stacking distance spaced together drafting rollers. They are preferably arranged by means of their two-armed lever 10 connecting pin 12 to a stationary punch 13 of the drafting 1 and floating in the sense that they invest in pressing their working element 11 from both sides equally to the lower roller.
- the working element 11 is designed here as a fluidic (pneumatic or hydraulic) cylinder / piston unit. It is understood that it can also be electromagnetically actuated, for example.
- the brake shoes 9 engage in an area between two Kordelfeldern or Riffelfeldern on the lower roller over which the cords ment 14 or Reef ment is performed and thus is very handy.
- the signal for simultaneously actuating all arranged on a lower roller brakes 8 is based on a frequency converter 15 which feeds the motor 6 of the middle lower roller 3 or the motor 5 of the output lower roller 4.
- the bottom rollers are decelerated by reducing the feed frequency to zero while maintaining the draft ratio set between them.
- the frequency converter via the line 16, a signal for releasing the brakes 8. They allow the taring of the lower roller, without their torsion would have opportunity to relax ,
- the output lower roller 4 may be equipped with one or more brakes 8 'when it undergoes torsion, the relaxation of which could impair the quality of the yarn produced.
- two brakes 8 ' are located at the beginning and end of the output lower roller 4.
