Definitions
- the invention relates to a device for unwinding Stranded spools with an overhead take-off from inside of a pot with a cylindrical cross section, driven stranded material spool, the longitudinal axes of Point the coil and pot in the same direction.
- Such a device is used for the stranded material spool the stranded material is unwound and, for example, a stranding machine fed for further processing of the stranded material.
- Devices for unwinding cords of twisted material are from the State of the art known. It is between different Distinguish types of unwinders. It are, for example, devices for unwinding across Pulling direction of the rope arranged axis of rotation Stranded spool known. Such unwinders are however not affected by the invention.
- Unwinding devices with overhead trigger can be a fixed or have a driven spool.
- An unwinder with a fixed strand spool is for example to German published application DE 3414396 remove. Since the stranded bobbin is fixed, it follows one turn per full turn when pulling off the stranded material of 360 °, the so-called withdrawal torsion. This in particular Trigger twist occurring with overhead deductions can become undesirable Lead loop formation. For this reason Processes and devices developed for the stranded material turn counter to the torsion so that the resulting Torsion is always zero if possible. This compensation the withdrawal torsion is also referred to as backward rotation.
- the starting point of the present invention is this reverse rotation by the inside of a in the cross-section of cylindrical pot rotatably arranged, driven Stranded spool generated from which the stranded goods thrown against the inner surface of the pot by centrifugal force and is slowed down there.
- the surface texture the inner surface of the pot and the speed of the Stranded spools determine the tensile force in the one to be unwound Stranded material works. Because with increasing speed and take-off speed the tensile force increases, that of the unwinder downstream processing stages, in particular Stranding machines, in their performance, d. H. in the maximum length that can be generated per unit of time generating rope limited.
- a performance increase through Increasing the speed of the stranded material spool is because of this associated risk of tearing the stranded material no longer possible.
- DT 25 08 896 A1 already has a wire dispenser known, the one arranged on a bobbin, motorized has driven coil.
- a cylindrical antiballoon organ is coaxial to the coil on the frame of the Wire dispenser attached to the radius of the Limit coil detached wire loop.
- the wire dispenser is to reduce the Friction of the stripped wire loop on the antiballoon organ the latter can be rotated together with the coil on a shaft.
- the invention is based on this prior art the task of a device for unwinding To create stranded spools that have even higher take-off speeds allowed and a stepless adjustment or regulation the tensile force in the stranded goods enables to the production output in downstream processing stages, especially stranding machines.
- the solution to this task is based on the thought that arises braking effect on the stranded material in the pot To be able to change the speed of the twisted material spool.
- the pot can be rotated about its longitudinal axis independently of the stranded bobbin is that the coil and pot have a common longitudinal axis and the pot is also connected to a drive is, the speeds of the drives for the coil and pot independent are adjustable from each other.
- the pot according to the features of the claim 1 is a particularly precise, in particular stepless Setting or regulating the tensile force in the stranded material in Depending on the take-off speed possible.
- the speed of the spool and pot can be freely specified any relative speeds between coil and pot, within the maximum allowable speeds for Adjust the coil and pot.
- the Braking effect and thus the tensile force in the stranded material works, change within wide limits.
- spool and pot rotate in the same direction and is the Speed of the coil greater than or at most equal to the speed of the pot.
- the stranded material drawn off from the stranded spool becomes more common Way through a hollow receiving axis for the stranded material spool led to a brake that is rotatably mounted.
- the tensile force acting in the stranded material can be applied via the brake can be set precisely.
- the brake can be rotated to reverse the twist stored.
- the invention is based on a schematic Drawing of the device for the unwinding of stranded material spools explained in more detail.
- the device according to the invention for unwinding cords of twisted goods hereinafter referred to as unwinding device overall designated (1). It essentially consists of a stranded bobbin (2) with two bobbin webs (10a, 10b), which are rotatable in a pot with a cylindrical cross-section (3) is arranged.
- the stranded material spool (2) is a spool drive (4), the pot (3) is assigned a pot drive (5).
- the unwinding device (1) also has one known brake (6).
- the pot (3) is on the front side facing the drives screwed to a flange cover (7).
- the cross section of the Pot (3) initially takes off from the flange cover (7) continuously to and runs in a cylindrical section (9) to towards the open end (8).
- the stranded material spool (2) on a take-up axis (11) pushed on and their coil cheeks (10a, 10b) between two quills (12), (13) locked, the quill (12) with a cover (14), which is then on the receiving axis (11) is postponed, connected.
- the receiving axis (11) has a passage (15) for the stranded material pulled from the stranded spool (2).
- the brake (6) consists in particular of pivot bearings (16), (17), guide rollers for the stranded material (18), (19) and the actual brake assembly (21).
- Both the pot (3) and the coil (2) are about their axis of rotation (22) rotatably and are driven by the pot drive (5) or coil drive (4) set in rotation.
- pot (3) and coil (2) thus rotate about the same axis (22), where both the speed of the coil and the speed of the Pot with not shown in the drawing known controls are freely selectable.
- Let her through any relative speeds between the coil (2) and the pot (3) adjust and thus the braking effects that spun off from the coil (2) in the direction of the inner jacket (23) Stranded goods and thus the tensile force in the stranded goods influence.
- the open on the inner jacket (23) The end face (8) of the stranded material is guided from there towards the axis of rotation (22) through the passage (15), the drives (5), (4) and the brake (6) out.
- Due to the incredibly simple measure according to the invention can be used in a device for unwinding cords with an overhead deduction and reverse rotation of the stranded material reduce the tensile force acting in the stranded material.
- the reduced traction allows higher take-off speeds and brings a higher productivity downstream Processes with themselves.
- stranded material refers to how it was not used in the above description only on ropes in the strict sense, but also on electrical ones Cables, light guide cables or the like.
- the term Single strand comprises the stranded material, each of one Stranded bobbin to a downstream processing stage, for example, a stranding point is performed. Even the single strand can in turn consist of several individual wires, single fibers, Strands or the like exist.
