Definitions

  • This invention concerns an alignment and drawing unit located downstream of a reel that feeds straightening and/or shaping and/or forming machines as set forth in the main claim.
  • the invention is placed downstream of a reel holding two or more rolls of wire rod or shaped sections for the metallic reinforcement of concrete for building work.
  • a reel is positioned upstream of a fast straightening and shaping machine suitable to produce reinforcement stirrups for building work which have a closed or open form and various dimensions, the stirrups being produced from reinforcement rods or sections of various cross sections.
  • This reel holds two or more rolls of wire rods or sections having advantageously different cross sections.
  • an alignment and drawing unit is positioned beween the reel and a processing machine and works on the axis of the normal path of the reinforcing wire rod or section.
  • the alignment and drawing unit has a drawing position and an inactive position.
  • This unit comprises appropriate arms, which during the movement from the inactive position to the drawing position engage the end of the wire rod or section protruding from the reel and take it to the alignment and drawing position.
  • At least two mating rollers are included of which at least one is powered.
  • Each of these two rollers comprises two arms which extend respectively upwards and downwards at an angle to each other at the front of their respective rollers.
  • the two arms of one roller are therefore approximately counterparts of the arms of the other roller.
  • Their reciprocal displacement can be achieved with a straight movement or a curved movement, which is advantageously substantially circular.
  • This movement can be substantially horizontal, substantially vertical or a combination of the two.
  • Each roller 11-12 comprises engagement arms 13 arranged at an angle to each other and protruding from their specific roller 11-12.
  • One of these rollers, the roller 11 in this case, is driven by a motor 14.
  • rollers 11-12 are supported and positioned on supporting arms 15 or on trolleys 16.
  • One or more actuators 17 are included to move the rollers 11-12 and to take them from an inactive position 18 to a drawing position 19. During this movement the engagement arms 13 engage a section 20 and convey it to a position of cooperation between the rollers 11-12.
  • rollers 11-12 are reciprocally thrust resiliently against the section 20.
  • a series of rollers 11-12 may be included instead of the two rollers 11-12.
  • Fig.2 shows that the embodiment can also be rotated by 90°, or else the trolleys 16 of Fig.2 can run on guides positioned at an angle to each other, for instance with their vertex upwards (not shown here) so as to reduce the overall lateral bulk.
