Definitions
- the invention relates to a winding spindle for a winding machine according to the preamble of claim 1.
- a generic winding spindle for a dishwasher is known from DE 196 07 916 AI. Such winding spindles are used in winding machines for winding preferably freshly spun synthetic threads into coils. For this purpose, one or more bobbins are successively mounted on the in the dishwasher on projecting winding spindle. For fixing the winding tube on the circumference of the winding spindle, a clamping device is provided which allows a tensioning and a relaxing of the winding tube.
- the clamping device is arranged in an annular space between an outer jacket bushing and an inner hollow spindle.
- the jacket and the hollow spindle are rotatably connected to each other, wherein the hollow spindle is driven by a drive shaft.
- the clamping device has a plurality of clamping body, which are guided in openings of the jacket bush and which are radially movable by moving an annular piston on the circumference of the hollow spindle to tension the winding tube or to relax.
- the annular piston is usually held by a plurality of springs in a clamping position. Only to relax the Spulhülsen, for example, to be able to remove full bobbins from the winding spindle, an activation of the clamping device is required.
- EP 1 456 108 furthermore discloses a winding spindle in which a plurality of support means are arranged between the jacket bushing and the hollow spindle and generate tension between the jacket bushing and the hollow spindle.
- the particular advantage of the invention is that the installation space for the clamping device can be reduced to a considerable extent.

- the springs are evenly distributed according to a preferred development on the circumference of the annular piston and guided in recesses of the annular piston. This makes it possible to produce a uniform axial displacement of the annular piston, so that the clamping bodies arranged in one plane can be guided synchronously.
- the springs are preferably designed as compression springs and clamped within the annular space between a stop and the annular piston. Since the operating times of the clamping device in the tensioned state are much greater than the operating states in the relaxed state, fatigue-proof springs can be advantageously realized. To relax, it is necessary that the annular piston is pushed against the spring force on the circumference of the hollow spindle back.
- a pressure fluid is preferably used, which is conducted by means of a pressure source in a pressure chamber which is bounded directly by a pressure surface of the annular piston.
- the annular piston is preferably formed in one piece and has the pressure surface at the end opposite the compression springs.
- the annular piston per clamping body on a clamping shoe which cooperates with the respective Klemmköpern and which is formed by an incision in the annular piston.
- the plurality of components of the clamping device can be reduced to a minimum, so that each of the clamping body is associated with a tensioning shoe through the annular piston.
- clamping bodies associated with the clamping shoes can also be connected as separate parts form-fitting manner with the annular piston. This makes it possible to form the instep shoes from another particularly slippery material.
- the clamping shoes are each connected by an elastic web to the annular piston. This results in each of the tensioning shoes a support directly on the circumference of the hollow spindle.
- the development of the invention has proven particularly useful, in which the clamping bodies each have a wave-shaped surface with several clamping edges or a weapon-shaped surface with a plurality of clamping points.
- the clamping bodies each have a wave-shaped surface with several clamping edges or a weapon-shaped surface with a plurality of clamping points.
- winding tubes made of cardboard thus form-fitting clamping connections can be generated.
- the spring according to the invention for use in the winding spindle according to the invention is characterized in that the flat turns are adapted to a curved plane corresponding to the respective annular piston diameter. This makes the installation space of the spring particularly compact.

- the winding spindle has an outer jacket 1, which is slipped over the circumference of a hollow spindle 2 and is held between a collar 23 and a cover 20.
- the hollow spindle 2 is coupled to a drive shaft 4 and rotatably supported by a hollow cylindrical spindle carrier 3.
- the connection of the hollow spindle 2 with the drive shaft 4 and the bearing of the drive shaft 4 and the hollow spindle 2 are not shown in detail in this embodiment, since they are generally known for such winding spindles and have only minor importance for the invention.
- annular space 5 is formed between the outer jacket 1 and the hollow spindle 2, in which a clamping device 6 is arranged.
- the clamping device 6 extends over the entire length of the jacket bushing 1 and, depending on the number of winding tubes to be accommodated on the winding spindle, has a plurality of clamping bodies 8 arranged distributed in normal planes.
- Fig. 1 and 2 two groups of clamping bodies 8 are shown, with which, for example, a winding tube 24 can be stretched on the circumference of the jacket bushing 1.
