Description

The invention relates to a device and a method for the continuous winding of artificial ones Threads, with the full bobbin by means of a double lever rotated by 180 ° with each bobbin change away from the drive roller and the empty bobbin is moved towards the drive roller.

It is known that when winding artificial threads, the full work spool while it is being pivoted away to be replaced by the drive roller at the same time with an empty bobbin. The usual devices are two reels, i.e. working and empty reels, on a two-armed lever or diametrically on a turntable attached, which or which are rotatably mounted on a one-armed lever. The bobbin change happens in that the one-armed lever is first withdrawn from the drive roller, to lift the full bobbin from it, and immediately afterwards turn the two-armed lever by 180 ° and is locked, the empty bobbin taking the place of the full bobbin, and then the one-armed bobbin Lever is swiveled back again, with the empty bobbin now resting against the drive roller. The string is placed on the swiveling empty bobbin when changing bobbins by hand, so that hardly any Material loss occurs.

In this device, the mounting of the two coils on the rigid double lever makes it possible to lift off the full bobbin from its holder and replacing it with an empty bobbin in the rest position only possible if the full bobbin can be withdrawn from the chuck in the axial direction. It requires a lot of space in the longitudinal direction of the machine, since the distance between two spinning positions is the same the double coil length in addition to the space required by the side-mounted levers, so a total of about must be equal to three times the coil length. In addition, the one-armed lever or the coil load-bearing two-armed levers are not firmly locked in the operating position, so that the coil is accordingly the increase in their diameter can shift in the course of the winding process. As a result the rigid connection with the empty bobbin can therefore interfere with z. B. when replacing the full bobbin in the rest position can be caused by clumsy operation on the Have an effect on the work bobbin and lead to the thread breaking.

The subject matter of the invention deals with these shortcomings in that full and empty bobbins are each connected to a single-arm lever arranged and both single-arm levers on the double lever with the help of known gears, such as epicyclic gear apparatus and method

The single-arm levers connected between the double lever and the coils make it possible to to pivot the coil out of the normal position when the double lever is locked in order to remove it from the Remove the area of the bobbins from the neighboring spinning units, remove them from their holder and pass through to be able to replace an empty tube without the other single-arm lever, which is currently in the working position is located on the drive roller, thereby being hindered or disrupted during the winding process.

It is now true in bobbin spinning machines with swiveling bobbin carriers, in which the bobbins are driven directly via gears, known by arranging the coil axes transversely to Machine longitudinal axis to achieve space savings in this direction. Such measures are however, in the case of a drive roller spinning machine whose drive roller runs in the longitudinal direction of the machine, not applicable.

The arrangement of gears in bobbin changing devices similar to that in the invention Device described is known per se. However, it is only through the combination of the

speed than the drive roller or full spool, it pulls thread material to a greater extent as the frictional engagement increases as a result of the deflection which, however, are not wound up to the same extent by the full spool that is running out can so that it begins to loop around the empty bobbin, which in turn leads to the thread tears between empty spool and full spool. The empty bobbin now leading the thread hits directly in front of the drive roller on one of a weight- or spring-loaded contact buffer 25 existing Damping device and is intercepted there so that it does not strike the drive roller 2 with full force.

It has also been shown that in special cases the inclination of the one-arm lever, which with its empty bobbin is just brought into working position, must be changed, otherwise the empty bobbin against parts of the spinning machine, e.g. B. could push the thread guide and the like. To this end recommends it is, as shown in Fig. 3, to attach slideways or guide rails 26 to the machine frame, against which the one-arm lever or a guide pin connected to it lays itself and which during the bobbin change from its normal, by the stop 15 on the planet gear 19 or 20 lead out a certain inclination.

By means of the device described above for the continuous winding of artificial threads it is possible, by starting the empty bobbin beforehand, to the desired one, by 30% above that of the Driving roller lying circumferential speed a lossless and completely automatic transition of the thread from the full bobbin to the empty bobbin. Removing the full spool from the spool holder can after swiveling out the respective one-arm lever outside of the range of Adjacent coils take place, so that the machine division by an essential compared to the previously known Devices can be reduced. Due to the separate storage of empty and full bobbins or Work and rest coil on the double lever and the locking of the double lever after pivoting Disturbing movements from working on the one-arm lever that is in rest position cannot affect the single-arm levers located in the working position are transferred.
