Definitions
- the present invention relates to a new type of thread tensioner usable on any type of textile material, and more particularly on machines making it possible to twist and / or twist threads of any kind.
- tensioning devices which comprise on the one hand, a pulley whose periphery has a friction layer and is in contact with the wire on at least part of its circumference, and on the other hand, means for braking said pulley.
- These pulley braking means consist of an eddy current brake in the form of an asynchronous type motor, the rotor of which is integral with the pulley shaft and the stator windings of which are supplied by a source. adjustable direct current.
- Such a type of tensioner which, in general, corresponds to the device which is the subject of US-A-3 797 775, is not satisfactory, in particular by the fact that it requires a supply of electric current and that it is therefore necessary to have as many supply connections as there are tensioning devices.
- the aforementioned FR-A-2 145 056 aims to overcome this drawback, the braking device which it describes being constituted by an electric generator whose rotor is secured to the pulley shaft, and whose armature is connected to a load resistor, the magnetic field of the generator being supplied by a permanent magnet.
- FR-A-2 167 957 describes a solution in which braking for guiding the wire is obtained by producing a magnet the number of magnetic poles of which is even, this magnet being placed opposite a disc the face of which is pierced several holes, disc which supports the wire guide pulley. Braking of the pulley is obtained by varying the distance between the disc and the magnet.
- the invention will be described for a tensioner used on a wiring machine, and in which the element communicating the tension, element which will be designated in the following description by the expression "pulley”, consists of two cups mounted on a hub and locked against each other with a nut to adjust the pressure between the cups and therefore to drive the wire positively. It is obvious that any other equivalent device could be used, for example, it would be possible to produce a tensioner according to the invention by passing the wire against the periphery of a drum or a simple pulley with groove.
- the wire tensioning device according to the invention is of the type comprising:
- the device according to the invention is characterized in that the means for adjusting the spacing between the magnets and the pulley to be braked, consist of:
- a first assembly exerting a push tending to bring the support of the lovers of the crown associated with the pulley up to a predetermined minimum value
- a second assembly exerting a counter-thrust, of adjustable value, tending to separate the magnets relative to the surface of the crown
- said counter-thrust means being constituted by a source of compressed air acting on the face of a piston mounted fixed on the axis, pressing against a bearing surface of the latter, and the other side of which is subjected to the action of the first thrust means, the supply of compressed air being carried out simultaneously on all the tensioners that the machine comprises via a common pneumatic line.
- FIG. 1 is an overview of a textile machine for making the wiring of two elementary son equipped with a tensioner according to the invention
- FIG. 2 is a detail view in longitudinal section of a tensioner produced in accordance with the invention.
- FIG. 3 is a front view of such a tensioner showing the way in which the passage of the wire takes place around the "pulley" for communicating the tension;
- FIG. 4 illustrates, top view, a plurality of tensioners equipping four positions of a textile machine, connected to a source of air supply under common pressure.
- FIG. 1 illustrates, schematically and seen from the side, a working position of a textile machine known as a "direct cable maker", making it possible to assemble two elementary threads by false twist.
- each working position therefore makes it possible to join together by twist two elementary wires (A, B) coming from two power sources (1,2).
- the wire (A) from the spool (1) passes through a turntable (3) or the like so as to form a balloon (4) inside which is placed the power source (2) for the wire ( B).
- the assembly of the two wires (A) and (B) is obtained by twisting at the meeting point (5), then the cable (6) formed is returned in a conventional manner, for example on a winding system (7) not communicating no additional twist.
- the call of the two wires (A) and (B) constituting the cable (6) is given by the winding speed in (7).
- tensioning systems (8,9) are provided for each wires (A, B).
- the tensioner (8) makes it possible to adjust the reserve length of the wire (A) around the plate (3) and acts as a shock absorber which absorbs the unwinding of the reel from the spool (1), which makes it possible to keep a ball
- the tensioner according to the invention is particularly suitable for being used to give tension to the wire (A) which passes inside the rotary plate (3) and forms the balloon (4).
- the stranding machine equipped with tensioners (8) therefore consists of a plurality of identical working positions arranged side by side, the tensioners (8) making it possible to ensure the tension of the wire (A) coming from the support ( 1) carried by a creel arranged, in this case, on the upper part of the machine, are individually mounted on a support plate (35) carried by said frame.
- the positioning of these tensioners is advantageously located on the machine frame at the level of the winding system, in front of the latter, the wire (B) being brought directly to the brake (9) located upstream of the wiring point (6) in the extension of the axis of the power source (2) of the wire (B).
- the tensioner (8) comprises, as an element allowing the tension to be communicated to the thread, a pulley made up of two cups ( 11,12) between which the wire (A) passes, these cups being mounted on a hub (13) which is itself mounted free to rotate by means of bearings (14) at the end of a shaft ( 15). Said cups (11,12) are locked on the hub by means of a nut-shaped assembly (16), which makes it possible to adjust the pressure of the cups against each other and consequently the tension that they communicate with the wire.
- the wire (A) passes through space between the two cups and is maintained at their interpenetration zone, the wire envelope around said cups being determined by two guides (17,39) (shown only in Figure 3), arranged respectively upstream and in downstream of the support plan.
- the hub (13) which supports the pulley comprises on its face opposite to said pulleys, a crown (18) made of a ferro-magnetic material such as for example based on ferrite.
- the means for ensuring the braking of the pulley are constituted by a plurality of permanent magnets (19) two in number in the present case, and being in the form of pellets having a diameter of 15 mm. These magnets are mounted concentrically with the shaft (15) on a support (20), itself immobilized inside a housing (21). The support (20) is blocked by means of screws (22), is immobilized in rotation relative to the shaft (15), but is however free in translation relative to the latter.
- the tensioner comprises means making it possible to vary the spacing between the magnets (19) and the crown (18) carried by the pulley, this variation being between a minimum value of 1 mm, which allows avoid any risk of interference due to geometric faults and a maximum spacing, depending on the power of the magnets, which in this case is 4 mm.
- These means for ensuring the adjustment firstly comprise a first thrust assembly which tends to bring the support (20) of the magnets (19) of the crown.
- This displacement is limited by a predetermined minimum value and is obtained, in the present case, by a assembly in the form of a spring (23) disposed around the shaft (15) and bearing, on the one hand on a fixed annular bearing (24) integral with the housing (21) and, on the other hand, on the rear face a piston (32) integral with the shaft (15), which allows the housing (21) to slide relative to the assembly (32-15).
- the housing (21) is designed so as to have on its rear face (33) a shoulder (34), which therefore makes it possible to produce a chamber (25) between the bottom of the housing and the face (26) of the piston, the other face of the piston bearing against a shoulder provided on the shaft (15).
- Seals (30) and (31) are provided to seal the chamber (25). Inside this chamber (25), opens the arrival (36) of a compressed air supply.
- the shaft (15) is fixedly mounted on a support (35) integral with the machine frame.
- the various elements of the tensioner are represented in their position where the magnets (19) are at a predetermined minimum distance, namely in the present case of the order of one millimeter, from the crown ( 18) mounted on the hub (13) in the pulley (P). This position provides maximum tension on the wire.
- the chamber (25) When it is desired to modify the value of the tension, the chamber (25) is supplied with compressed air, which therefore tends to push back the piston (32) which exerts a counter-thrust on the spring (23), and therefore tends to move the housing (21) which carries the magnets relative to the shaft (15), in the direction going to the left if we consider Figure 2, which will increase the spacing between said magnets and the crown (18). Consequently, the braking performed by the magnets tends to decrease.
- the displacement of the magnets relative to the pulley is obtained by displacement of the housing which supports the magnets on the shaft which is kept fixed on the machine. It could be envisaged to proceed in reverse, that is to say to mount the fixed housing on the machine, which will then cause the displacement of the pulley relative to said housing.
