Definitions
- the invention relates to a winding spindle according to the preamble of claim 1.
- Winding spindles are used in winding machines, which serve to wind continuously tapering threads into spools.
- the threads in the winding machine are initially changed by a traversing device transversely to the thread running direction and guided over a rotating pressure roller.
- the pressure roller sets the threads on each of the wound coils to be wound.
- several coils are arranged in alignment one behind the other on a common winding spindle. This makes it possible to wind several threads at the same time.
- the full bobbins and the empty tubes, on which the bobbins are wound up, are taken axially from the winding spindles during an exchange or attached to the winding spindle.
- the winding spindles are cantilevered cantilevered.
- a winding spindle with integrated clamping means is known for example from the patent application DE 101 63 832 Al.
- the winding spindle is essentially formed by a tubular support which is connected to a driven and rotatably mounted shaft. Outside the tubular support, the clamping means are provided, which are enclosed by a further tubular holder.
- the outer diameter of the winding spindle is thus determined by the diameter of the holder.
- the diameter of the tubular support which is decisive for the static and dynamic properties of the winding spindle, is smaller by twice the thickness of the clamping means. This loss of space for the wearer is particularly painful since the bending stiffness of a pipe in the fourth power depends on the diameter.
- the spindles are now designed for 8 or more spools, so that the spool spindles have corresponding overall lengths that are dynamically soft and thus easy to excite vibrations.
- high winding speeds are required by the winding spindles, which lead to correspondingly high speeds of the winding spindle, which has a vibration excitation in a wide frequency band in the course of the winding cycle result.
- Another conflict of objectives arises from the requirement to store as much volume in a coil, which prohibits large inner diameter of the coils and thus large outer diameter of the winding spindles.
- a winding spindle wherein the clamping means are associated with a short length portion of the holder, wherein the clamping means for fixing the sleeves act on at least one of the sleeves, and in which the sleeves frictionally and / or positively as a stack of tubes on the circumference of Halters are held.
- the advantage is that a tensioning device can be used which does not extend over the entire length of the winding spindle, as is the case with tensioning devices which individually radially tension each sleeve.
- the clamping means are assigned to a cantilevered side of the holder and in which an axial stop for the sleeves is provided on an opposite bearing side of the winding spindle.
- the arrangement at the projecting end is based on the knowledge that the structure in the region of the projecting bearing is particularly relevant for the static and dynamic rigidity of the winding spindle. Due to the relocation of the clamping device tion to the projecting end of the winding spindle is now more space for a rigid design of the winding spindle available. Thus, particularly long-projecting winding spindle can be created with low bending tendency for simultaneously winding a plurality of coils.
- the clamping device is located at the projecting end of the winding spindle with one or more clamping means which exerts an axial clamping force in the direction of the bearing on the sleeve assigned to the projecting end of the winding spindle.
- the clamping force acts in the axial direction and can be transferred directly to the sleeve stack for fixing all sleeves.
- an axial clamping force is transmitted directly to the end face of the sleeve which is assigned to the projecting end of the winding spindle.
- the clamping device is designed such that the clamping means generate at least one last sleeve, a radial clamping force.
- the positive connection of the sleeves is used within the sleeve stack, in order to obtain a fixation and entrainment on the circumference of the holder.
- the sleeves are previously pushed together to the axial stop on the circumference of the holder, and then fixed by a partial clamping.
- the clamping means have an advantageous effect on at least one of the sleeve.
- partial clamping can also be achieved if several sleeves at the end of the sleeve stack are clamped by the clamping means.
- the clamping means are formed so that during the clamping operation in a first step, the sleeves are clamped axially and then in a second step, the radial clamping force is applied.
- These steps can be executed successively, merge into one another or be executed in reverse order. Decisive is that the friction due to the radial clamping is always high enough to apply the axial biasing force.
- the clamping means required for generating the axial clamping force are preferably arranged on the bearing side of the winding spindle.
- the radially clamped sleeves serve as a stop for the axially clamped sleeves on the circumference of the winding spindle.
- the contact surface on which the sleeve stack bears against the axial stop is provided with a friction-increasing structure.
- a friction-increasing structure This can be done, for example, by a rough surface or by a profiling, wherein the elevations of the profiling press into the softer structure of the sleeve end face.
- the profiling of the contact surface is equipped with a plurality of drivers, which cooperate with a plurality of recesses in the end face of the sleeve. This allows high torques to be transmitted to the sleeves and the tube stack in particular even without axial clamping forces or with only slight axial clamping forces.
- the end faces of adjacent sleeves have a plurality of indentations and a plurality of projections resulting therefrom, which cooperate within the sleeve stack such that the torque is transmitted in a form-fitting manner to each of the sleeves.
- the end faces of the sleeves are provided with a friction enhancing structure which also contributes to the transmission of the torque.
- a further development of the invention uses an intermediate ring between two adjacent sleeves which ensures torque transmission and also ensures centering of the sleeves.
- the intermediate ring on means such as a centering diameter and abutment surfaces with a congruent shape for receiving the end faces of the sleeves.
- the centering of the sleeves on the winding spindle is achieved in that the winding spindle is provided on its outer circumference with radially resilient fixing means.
- these resilient fixing means are formed by axially provided on the outer circumference of the winding spindle strips. It is within the ability of a person skilled in the art to design these strips so that a centric fixation of the sleeves on the winding spindle is ensured.
- the clamping device of the winding spindle is designed so that the sleeves are tensioned in the energy-free state. When supplying energy from the outside, the sleeves are relaxed.
- the supply of energy to the cantilevered side of the winding spindle This has the advantage that no supply lines are guided through the areas of the winding spindle that are relevant for the rigidity.
- the development of the invention has proven particularly advantageous, in which the longitudinal section of the holder accommodates the tensioning device extends to a bearing point of a drive shaft connected to the holder. This makes it possible to perform the drive shaft with the largest possible diameter.

- the holder 29 has no diameter step in the area of the clamping means 8, as long as the clamping means 8 are completely retracted during the decompressing movement 10 ,
- the expansion movement 10 includes a radial movement of the clamping means 8 inward and successively or simultaneously a movement of the clamping means 8 in the direction of the projecting side 6. This relaxes the sleeves 2 and at the same time the clamping means 8 are moved back so far that the sleeves 2 on the Clamping means 8 can be withdrawn away.
