Devices on spinning machines have already become known, which bring about an automatic lowering of the ring rail after the coils have come to a standstill This type of installation involves lowering the hanging bench by means of an auxiliary motor, which is put into operation under a switch and in the lower end position via another Switch is shut down.

With this device it is possible to avoid manual lowering, but there is a risk of thread breakage when lowering.

The present invention now aims to provide a device by which the above-mentioned risk is largely eliminated "The device according to the invention is characterized in that the drive means are electromechanical Have coupling, the input part of which is in constant drive connection with the drive of the drafting system cylinder stands and whose output member is coupled to a take-up roller, on which one end of a flexible tension member is connected, the other end of which was in operative connection with the ring rail

An example embodiment of the device according to the invention is shown in the drawing. Show it:

Has eye 25, in which two ball bearings 26, which are spaced apart by a ring 27, are received . A coupling shaft 28, which is secured against displacement by snap rings 29, is mounted in the ball bearings 26. At the upper end of the W _e lle 28 a bevel gear 30 is mounted, which meshes with a bevel gear 31 on a shaft 31 'in engagement. The shaft 31 'is driven by gear wheels present on the spinning machine as a function of the front cylinder 18.

The input part 33 of an electromagnetic clutch 32 is rotatably mounted on the shaft 28 at 34. In a corresponding manner, an output part 35 of the coupling is at 36 arranged in a rotationally rigid manner on a shaft 37 which is separate from the shaft 28. The shaft 37 is supported in ball bearings 38 and 39, which are provided in the partition wall 23 and a lower end wall 40, with snap rings 41 on opposite sides Secure sides of the bearing 39 against axial displacement.

On the shaft 37 a take-up roller 42 is rotatably mounted, which, in contrast to the coupling 32 in the upper compartment 21, is located in the lower compartment 22 and has a hub 43. The illustrated mounting of the shafts 28 and 37 ensures trouble-free and long-term operation.

The roller 42 is rigidly connected to the shaft 37 by a pin 44. A steel cable 45 of a predetermined length is wound onto the cylindrical surface 46 of the roller 42. The diameter of this surface 46 is adapted to the delivery speed de "drafting unit in a suitable manner to a lowering of the ring rail at a suitable speed to bring" on the shaft 37 can be 42 substituted with different diameters against each other for this purpose rollers "

One end of the steel cable 45 is anchored in an opening 48 of the roller 42 by means of a clamping screw 47. The steel cable is wound around the roller 42 in several turns and is secured against sliding off by the bottles 49.

A locking disk 50 is fastened in a rotationally rigid manner on the shaft 37 by means of a screw 60 arranged in its hub 59. The locking disk has a radial groove 51 in which a part 52 of a locking pin 53 engages, which in turn is in a sleeve 54 is slidable at 55 in the front wall of the housing. A spring 56 surrounds the shaft portion 57 of the Pin 53 and pushes it radially inward. On the other hand, the pin can be fastened to the shaft 57 by means of a

Knob 58 can be pulled radially outward. The pencil slides with its part 52 on the surface of the disc 50 until the groove 51 is opposite the pin, so that the latter can enter this groove under the action of the tongue.

A relatively strong spiral spring 61 surrounds the hub 43 of the roller 42, one end of which at 62 on the hub and whose the other end is anchored at 63 to the side wall of the housing. This spring is tensioned before the steel cable is connected in order to exert a constant tension on this and to prevent the steel cable from becoming slack or get caught during operation.

The free end of the steel cable 45, since it is guided through an opening 64 in a removable cover 65, is attached to an arm 67 which in turn is adjustably secured at 67 'on a conventional two-armed lever 68'. The lever 68 'is at 68 on a W _e lle 69' of the spinning machine and carries a pivotally mounted lifting roller 69, on the screen via a cam 70, the lifting rod 15 is supported, which passes through the spindle rail at the 71st As can be seen from FIGS. 1 and 2, adjacent levers 68 'are connected to one another by links 71. Arms 72 'are provided on shafts 69',

carry the weights 73 *, which are the weight of the ring bench and balance this normally in the in Pig. Hold 1 dash-dotted upper layer.

To limit the upward movement of the ring rail, a switch 72 is arranged on the housing 20 in such a way that its Actuator 73 protrudes into the path of the ring rail. A second switch 80, preferably a roller operated microswitch, is attached to housing 20 at 81. This switch 80 has an upright pin 82, the one Roller 83 carries and under Peder load against the locking pin. 53 or its part 52 is pressed. Y / erm the locking pin 53 enters the groove 51 with its part 52, the pin 82 is pressed downward by the switch 84. The switch 80 is normally closed, while switch 72 is designed as a timer and normally is open. The switch 72 will normally remain closed for at least a minute while the ring bank is lowered in order to then open again automatically. Depressing pin 82 opens switch 80, to disengage the clutch 32, which was engaged by the switch 72, when the Pin 52 locks the locking disk 50 in the lower end position of the ring rail.

Like from Pig. 2, a plug 85 is provided for connection to an AC power source. The connector 85 is via a conductor 86 to a rectifier 87 and from this via a conductor to one terminal 89 of the Coupling 32 connected. The other port 90 is across a conductor 91 connected to one terminal of the upper limit switch 72. A conductor 92 leads from the other terminal this switch to one connection of the lower limit switch 80, the other connection via a Conductor 94 and the rectifier are connected to connectors 85.

In operation, the ring rail is raised during the winding of the bobbins 13 in a Lags that is above the in ilg. 1 The lowest end position shown in solid lines lies. The front cylinder 18 is continuously driven and thereby also drives the shaft 31 and the shaft 28 of the input part the clutch 32 on. The switch 72 is open because the ring rail has not yet reached the top layer, so that the clutch is disengaged and the shaft 37 with the roller 4-2 stands still.

When the uppermost position of the ring rail is reached, in which the bobbins 13 are filled, the switch 72 is closed,

which thus closes the circuit to the clutch via the normally closed switch 80. This engages the clutch or the input part transmits a torque to the output part, as a result of which the shaft 37 is rotated and the steel cable is wound onto the roller 42. The levers 68 ^{f are} pivoted counterclockwise, while the weights 73 'are raised, while the ring rail is lowered at the desired speed, which is determined by the transmission ratio resulting from the roller 42.

At the point in time at which the time switch 72 is again opens, the ring rail is already in its lowest position, in which the switch 80 by the collapse of the Locking pin 52 opened in the groove 51 of the disc 50, the The clutch is disengaged and the pulley 42 is prevented from unwinding the steel cable 15 by the locking disk.

Now the full bobbins can be removed from the spindles 12 and replaced by empty tubes that are back into the usual way to be wound. Before that, however, the mechanism that controls the structure must be switched on and then the pin 53 can be pulled out to release the locking disc. The switch 80 is closed and

the ring bench moves under the influence of the weights 73 * upwards to the lowest working position, after which the spinning process can start again. During the upward movement of the ring rail, the steel cable 45 is unwound from the roller 42 and held under tension by the spring 61. The locking pin 52 no longer enters the groove 51 until the ring rail is completely lowered again, since the winding or unwinding of the steel cable takes less than one full turn the disc takes place.

The device described not only has the advantage that the lowering of the ring rail is matched to the delivery speed of the drafting system and thus yarn breaks can largely be avoided, but it also allows the ring rail to be secured in a position determined by the rotation of the locking disc when the Drive via the coupling is interrupted _o The device described has

Thanks to their special design and simplicity, they also have the advantage that they can be used both on new machines and on those in which the lowering of the ring rail was previously

can be installed quickly.
