  • the supports (4) are fixed by bolt to the race (1), containing the shaft inside (5), mounted by the roller bearings (6), with wheels (7) on their end, which work as a guide, allowing the vertical movement of the race (1).
  • the bus bar (9) is assembled inside the race (1) and movable arm (2) and, in accordance with figures 8 (note: see annex), is composed of shaped rubber (54) and copper blade (55) whose purpose is to feed electrically the movable car (27) and enable shift of it.
  • the race (1) and movable arm (2) in accordance with figures 4A, 4 and 8, are made of metallic plate, with two shapes installed in parallel and are separated by spacers (56), in welded construction.
  • the metallic panel (10) is made of metallic shapes, welded, having opening on two sides where the guiding plates (11) are housed, whereby the wheels (7) shift, thereby allowing vertical movement of the race (1).
  • the motor-driven reducer mounted on the upper part the metallic panel (10) and has the function of transmitting the turn to the spindle (14) which drives the nut (15) which is mounted inside the race (1), thus vertically shifting the race (1).
  • the motor-driven reducer (17) is mounted at the lower part of the metallic panel (10), whose function is to pull the shaft (18), resulting in the horizontal movement of the metallic panel (10) and race (1) through the wheels (20) in the rail (22).
  • the metallic shapes (21) are mounted the wheels (24), which are actuated by the motor-driven reducer (25), which through the shaft (26) causes the horizontal shift of the whole machine assembly, fed electrically by the cable realer (45).

  • the use of the wrapping machine assembly concerned consists of the following phases:
  • the movable car (27) and the roll (37) of the skid (57) are actuated by the motor-driven reducer (43), syncronizing the speed of the coil (58) rotation with that of the movable car (27). With these movements the movable car (27) will shift inside and outside the coil (58) by the race (1) and movable arm (2) packaging it completely. • After the coil (58) is packaged, the tape (59) is cut, the movable arm (2) is open and the column (60 moves back to allow removal of the coil (58) from the skid (57).
  • the wrapping machine concerned presents certain advantages over the one previously used, namely:
  • the race (1) and movable arm (2) upper parts are oval unlike those of PI 9401378-0 that were in semi-circle which allows a constant stretching of the packaging tape (59) thus avoiding loosening in the last packaging stage of the coil (58), which causes penetration of impurities.
  • the race vertical movement (1) is performed by means of nut (15) and spindle (14) installed vertically, which differs from the mechanical arms of the machine PI 9401378-0 and allows that any coil diameter is used.
  • the rolls (37) of the skid (57) differ from the provious machines as it is only one driven and rubber-coated roll and the other one free with steel body, in order to avoid defects in the first turns of the coils(58).

Abstract

L'invention concerne une amélioration destinée aux machines à emballer les feuilles et les bobines d'acier, les fils laminés, les matériaux non ferreux, les produits plats et longs en utilisant des bandes de papier, des matières plastiques à faible et forte densité, des textiles mono et bi-orientés tels que le raphia, des mélanges composés de papier et de plastique avec ou sans traitement chimique. Ces machines sont employées pour l'emballage des produits finis dans l'industrie sidérurgique. Elles comportent une navette (1), un bras mobile (2), une colonne de levage et de déplacement vers l'avant (60), une base support de colonne pour la machine fixe (23) et la machine mobile (61), un chariot mobile (27), un plateau pour bobines (57) et un panneau de commande électrique. Pour obtenir le mouvement vertical (1), on utilise un système fonctionnant par écrou (15) et broche (14), qui permet d'emballer des bobines de diamètre extérieur quelconque. La base support de colonne pour la machine mobile (61) permet à cette machine de se déplacer et, ainsi, d'emballer des produits à la sortie des chaînes de traitement.
