Definitions

• the invention relates to a ring spinning machine with a lifting device for moving up and down at least ringbanks and possibly thread guides and balloon constriction and at least one of the weight of at least one of these components compensating spring.
• the arrangement of the springs in a frame containing the lifting device allows to mount the springs already in the factory, which speeds up the assembly work in the spinning and simplifies.
• the formation of the totality of the springs as a spring register allows a simple adjustment of the number of preferably uniform springs on the weight to be equalized different lengths and / or heavy ring banks and optionally the balloon constriction rings and the wandering thread guide.
• the system of the arrangement in side view of a ring spinning machine is shown schematically.
• the lifting device 1 for driving the ring banks 2 is arranged in a frame 3, which can contain, in addition to the drive of the ringbanks, further working or drive elements of the ring spinning machine, for example suction devices, drafting system drives or control devices.
• the lifting device 1 of the ring banks 2 comprises a stationary in a frame 3 rotatably mounted lifting shaft 4, on each of which a drum 5 is attached to both sides of the ring spinning machine.
• a tension member 6 is fixed, which is guided over freely rotatable pulleys 7 and 8 and to which each one of the ring banks 2 is attached. It is understood that the two tension members 6 run on both sides of the ring spinning machine over its entire length and the sections of each of the two ring banks are attached to a branch 6 'of the respective tension member 6.
• the tension members are accordingly held taut by the weight of the ring banks.
• the ring banks 2 contain the spinning rings 9, which are penetrated by the spindles 11 fastened in the spindle banks 10. The ring banks 2 are to move to build the Kopswicklung up and down and gradually switch upwards.
• Helical gear 13 and is shown as a worm wheel 14 and which is driven by an electric motor 15.
• the electric motor is reversible in its direction of rotation and changeable in its speed. It is functionally supplied via a control device 16 with supply voltage of variable frequency, which is generated in the control device via a frequency converter.
• the control device can be acted upon for this purpose via a control line 17 from the parent control device of the ring spinning machine.
• At least one further drum 18 is fastened, to which a plurality of helical tension springs 19 are fastened via a flexible tension member 20.
• the springs are articulated at their other end in eyelets 21 to the stationary frame 3.
• the circumference of the drum 18 may be circular.
• a ring spinning machine can be equipped with a corresponding number of springs.
• the flexible tension members 20 may also be attached to one or more arms disposed on the lift shaft 4.
• Pivoting range of the arm can then be arranged so that its decreasing lever arm reduces the increasing with increasing excerpt pulling force of the springs 19 on the lifting shaft 4. Since the weight of the ring banks remains unchanged, the traction of the spring register but this weight is not compensated in all cases and over the entire stroke range, compensation is only approximately possible. It is advantageously chosen so that it is given at about half the extension length of the springs. As a result of this weight and force compensation of the electric motor 15 has to overcome only the difference and the bearing friction of the working organs. It can therefore be sized small and copes with the mass reversal when changing the direction of movement of the ring banks easily.
