Definitions

  • the invention relates to a device for driving by traction a long material of substantially constant cross section, such as wire, cable, sheath or strip comprising two surfaces which move in synchronism and move parallel to each other over a length. large with respect to their spacing so as to enclose between them the long material to be driven, said surfaces comprising on their faces which are opposite in this zone of parallel displacement of the projections creating on the long driven material alternating compression points and free zones, the projections of at least one of the surfaces being partially elastically deformable.
  • a long material of substantially constant cross section such as wire, cable, sheath or strip
  • two surfaces which move in synchronism and move parallel to each other over a length. large with respect to their spacing so as to enclose between them the long material to be driven, said surfaces comprising on their faces which are opposite in this zone of parallel displacement of the projections creating on the long driven material alternating compression points and free zones, the projections of at least one of the surfaces being partially elastically deformable.
  • the drive of a long material with constant section is difficult to implement in a safe and repetitive manner, without slipping, and with high precision. These qualities are however required when, for example, the drive device is intended to supply a cutting machine which has to supply precise lengths of the long material.
  • Another device which consists of two parallel belts of which at least one is driven and between which the material is clamped.
  • This device is of reduced cost and size, but does not make it possible to obtain a safe drive, without jerks or stuffing, without sliding and with great precision.
  • These defects are due to the fact that the long material passes between two opposite rollers belts whose spacing has a finite dimension. As soon as the long material has an increase in cross-section, for example due to deformation, blistering, a surface defect, etc., the arrival of this increased cross-section between the rollers produces a blockage, which can go as far as blocking of the device. If one of the rollers is given clearance relative to the other, the tightening of the long material becomes insufficient and slipping occurs.
  • Another known device consists of two knobs facing each other and one of which is motorized.
  • a drive device for fabric in a sewing machine comprising two notched endless bands moving parallel to one another over a large part of their length by creating alternating compression points and free zones on the displaced fabric.
  • the notches of the endless bands are formed by teeth in one piece with the band, therefore elastic.
  • provision is made to be able to rotate one of the endless bands, with its pinions and pulleys, relative to the other band.
  • Such a device is of expensive and fragile construction.
  • the present invention aims to provide a new device which does not have the drawbacks of known devices, which is simple, solid, economical and compact, which ensures precise driving even with high tensile forces and at high speed, without risk of deterioration. of the area of the long material.
  • a second surface is constituted by the bottom provided with projections, for example knurled, of a central groove of a pinion meshing with the projections of a first surface.
  • the entrainment of the long material over a significant length between two surfaces pressing it at a large number of points, associated with the synchronization of the surfaces, is done without possible sliding, over the entire length of the zone of parallelism of the two surfaces.
  • the deformability of the projections of at least one of the surfaces makes it possible to absorb all the regional variations in section without releasing the pressure of the projections on the other sections of the long material, therefore without producing any slippage. This deformability further limits the point pressures, thus avoiding deforming or marking the material.
  • the first surface is formed by an endless band carrying notches on its outer surface.
  • an embodiment of the invention provides that one of the movable elements is connected to a length measuring device, for example by counting pulses.
  • the measuring device comprises a pulse emitter connected to at least one detector for passage of the projections of one of the surfaces.
  • the use of several detectors makes it possible to increase the measurement accuracy by reducing the apparent pitch.
  • the device according to the invention comprises an endless belt 1 stretched on rollers 2, 3, 4, 5 and whose outer surface carries notches 6 elastically deformable. Between two rollers 2 and 5, the strip 1 is clamped against a driving pinion 7 whose teeth 8 mesh with the notches 6 of the strip 1.
  • the driving pinion 7 has a central groove 9 whose bottom 10 is knurled.
  • the material to be transported is brought to the input roller 2 which is in front of the first point of contact between the strip 1 and the drive pinion 7 so as not to create a finished dimension crossing point.
  • the wire 11 is gripped and transported against the knurled bottom 10 of the groove 9 of the pinion 7, while being held in points by the notches 6 of the band 1, throughout the zone of overlap of the band 1 around the pinion 6.
  • the wire 11 leaves this overlap area before the last roll 5 so as not to create a finished dimension crossing point.
  • a free pinion 7 ′ identical to the motor pinion 7, replaces the motor pinion 7.
  • the synchronous drive is provided by a motor pinion 11 of small diameter engaged with the notches 6 of the strip 1 between the intermediate rollers 3 and 4.
  • the motor pinion 12 is mounted directly at the end of the motor shaft 13 and provides a significant tensile force on the wire 11.
