Definitions
- the invention relates to a device for laying a thread according to the preamble of claim 1.
- the guide rod is rotatably mounted on egg ner pivot axis.
- a drive acts on the opposite drive end of the guide rod. Since the drive end of the guide rod moves relative to the pivot axis on a circular path, the drive end is driven via a Gleitverbin extension with a multi-link gear, which is activated by a grooved washer to a uniform reciprocating movement. Due to the shape of the circumferential groove in the groove disc and its position, the guide end of the guide rod is moved back and forth, with a constant laying width prevailing. Such mechanical coupling gears are therefore completely unsuitable to be able to lead a Fa with the most variable possible laying width.
- the drive is designed as an oscillating linear drive and that the linear drive is connected to the drive end of the guide rod by a coupling member.
- the invention has the particular advantage that the pivoting movement of the guide rod can be generated solely by a straight linear movement.
- a simple coupling element is provided between the linear drive and the guide rod, so that the relative mobility between the guide rod and the linear drive is guaranteed.
- the guide rod can be swiveled quickly and very precisely by the linear drive.
- the development of the invention is preferably carried out in which the coupling member is formed by a push rod that is connected to the drive end of the guide rod by a swivel joint and by a second swivel joint a ram of the linear drive is connected.
- the linear movement of the linear drive can be transmitted directly to the drive end of the guide rod via the push rod.
- the linear drive is formed by a pneumatic or hydraulic or electrical actuator which linearly moves the plunger back and forth within one stroke.
- the laying width at the leading end of the guide rod is determined by the stroke of the linear drive.
- the stroke of the actuator is preferably designed to be adjustable. Different coil widths or biconical coils can thus be wound in a simple manner.
- the development of the inven tion is preferably carried out in which the leading end of the guide rod at the end of a guide leg and the drive end of the guide rod at the end of a drive leg are formed, the pivot axis in the area between the guide leg and the drive leg is arranged and wherein the guide leg and the drive leg span an angle in the range of 50 ° to 180 ° between them.
- L-shaped guide rods can be used to convert the stroke movement of the linear drive into a pivoting movement of the guide end.
- the development of the invention is provided in which the guide leg has a length which is many times greater than a length of the drive leg. In this way, the laws of levers can be used to create the largest possible laying widths with a relatively small stroke.
- a laying width for laying the thread is derived from a calculation formula as a function of The stroke of the linear drive and a length geometry of the guide rod result as follows:
- the laying width is designated with V, the length of the guide leg with LF, the length of the drive leg with LA and the stroke of the linear drive with H.
- the laying width achieved when laying the thread must be determined in advance.
- the laying widths can be determined in advance, especially for performing stroke breathing and asymmetrical coils.
- the inventive device for laying a thread is tert erläu below on the basis of some exemplary embodiments with reference to the accompanying figures.
- FIG. 1 schematically shows a view of a first embodiment of the device according to the invention for laying a thread.
- FIG. 2 shows schematically a view of a further embodiment of the device according to the invention for laying a thread
- a first embodiment of the device according to the invention for laying a thread is shown schematically.
- the embodiment has a guide rod 1, which is formed from a guide leg 1.1 and a drive leg 1.2.
- the guide rod 1 is rotatably mounted on a stationary pivot axis 4.
- the pivot axis 4 is arranged on the guide rod 1 in the area between the guide leg 1.1 and the drive leg 1.2.
- the guide rod 1 is L-shaped so that an angle is set between the guide limb 1.1 and the drive limb 1.2.
- the angle ⁇ can be in a range between 50 ° and a maximum of 180 °.
- the guide leg 1.1 of the guide rod 1 has an effective length, which is identified in Fig. 1 with the reference numeral LF.
- the drive leg 1.2 has an effective length that is entered with the reference symbol LA in FIG. 1.
- the length LF of the guide leg 1.1 is here many times greater than the length LA of the drive leg 1.2.
- the effective lengths LF and LA relate to a pivot axis 4 as a pivot point and a pivot point 8.1 on the drive leg 1.2 as well as a guide end 2.
- the guide leg 1.1 has a thread guide 3 at its guide end 2.
- the drive leg 1.2 is connected to a drive 9 at a drive end 5.
- the drive 9 is formed by a linear drive 6 which has an actuator 6.1 and a plunger 6.2.
- a coupling element in the form of a push rod 7 is arranged between the plunger 6.2 and the drive end 5 of the drive arm 1.2.
- the push rod 7 is connected to this with a swivel joint 8.1 with the drive end 5 of the drive leg 1.2.
- the push rod 7 is coupled to the plunger 6.2 of the linear drive 6 with a second swivel joint 8.2.
- a control device 10 is assigned to the actuator 6.1.
- a guide speed and a stroke of the actuator 6.1 can be controlled by the control device 10.
- the actuator 6.1 can have pneumatic, hydraulic or electrical means for moving the plunger 6.2.
- the re mean value and amplitude of the slide movement H (t) can be set. In this way, both stroke breathing and a storage position along the laying width V can be set.
- the hub H thus forms the adjusting means to influence the laying width of the Füh approximately end 2 and change. Due to the geometric relationships between the drive leg 1.2 and the guide leg 1.1, the Ver laying width V can be predetermined with the help of the stroke H of the linear drive 6. The following applies:
- the laying width V can be determined for each stroke H with the help of the lever geometry of the guide rod 1.
- the stroke on the linear drive 6 is set by the control device 10.
- the laying width can also be changed while a coil is being wound in order, for example, to achieve stroke breathing or a specific shape of the coil.
- the linear drive 6 In the exemplary embodiment shown in FIG. 1, the linear drive 6 generates a vertically oscillating stroke movement in order to drive the guide rod 1. Alternatively, however, there is also the possibility that the linear drive 6 executes a horizontal Hubbe movement.
- Fig. 2 an embodiment is shown for this purpose.
- the exemplary embodiment in FIG. 2 is identical in structure to the exemplary embodiment according to FIG. 1, so that only the differences are explained at this point and otherwise reference is made to the aforementioned description.
- the guide rod has a Füh approximately leg 1.1 and a drive leg 1.2, which form an angle a of 180 ° between them.
- the guide rod 1 is formed straight ahead, with a pivot axis 4 between the guide leg 1.1 and the drive leg 1.2 is arranged on.
- the drive 9 is coupled to the drive end 5 of the drive leg 1.2.
- the drive 9 in this embodiment also has a linear drive 6, which is formed from an actuator 6.1 and a plunger 6.2.
- the plunger 6.2 is a Push rod 7 is connected to the drive end 5 of the guide rod 1.
- the push rod 7 is connected to the drive arm 1.2 via a swivel joint 8.1 and to the plunger 6.2 via a second swivel joint 8.2.
- the plunger 6.2 is guided to and fro in the horizontal direction within a stroke H by the actuator 6.1.
- the actuator 6.1 is controlled by the control device 10.
- the push rod 7 forms the coupling member in order to enable a relative movement between the plunger 6.2 on a linear path and the drive end 5 on a circular path.
- the swivel joints 8.1 and 8.2 ensure a firm connection between the linear drive 6 and the guide rod 1 in every position.
- the device for laying a thread is shown as it can be used, for example, in a winding point for winding a thread.
- the plunger 6.2 of the actuator 6.1 could be connected to several guide rods via several coupling links.
