Definitions

  • a mechanism for turning over relatively flat articles being advanced by a conveyor which includes means for lifting the front of each article upwardly, when it reaches a predetermined point, to pivot about its rear edge resting upon the conveyor, means for engaging the rear edge to prevent sliding movement of the article in a direction opposite to the direction of motion of the conveyor, and support means for receiving the article when it overbalances about its rear edge, the said lifting means thereafter being lowered to control forward sliding movement of the edge, initially the rear one but now the forward one, of the article.
  • the present invention consists in a mechanism for turning over relatively flat articles being advanced by a conveyor, which includes means for lifting the front of each article upwardly, when it reaches a predetermined point, to pivot about its rear edge resting upon the conveyor, and means for engaging the rear edge to prevent sliding movement of the article in a direction opposite to. the ,directionof motion of the conveyor, support means being provided for receiving the article when it overbalances aboutits rear edge, the saidlifting means thereafter being Ioweredto control forward sliding movement of the edge, initially the rear onebut now the forward one, of
  • FIG. 1 shows diagrammatically aside view of apparatus according to the present invention
  • FIG. 2 shows an end view of the apparatus of FIG. I with certain parts removed for clarity
  • FIGS. 3, 4, 5 and 6 show, diagrammatically, four successive positions in the operation of the-turnover mechanism of the apparatus of FIG. 1.
  • the upper run or flight of the belts 1 is arranged to conveyrelatively flat motor car panels (not shown) guided on each side by adjustable guides 14 from a press in the direction from left to right as shown in FIG. I.
  • leading edge 9a of each panel 9 FIGS. 3-6 When leading edge 9a of each panel 9 FIGS. 3-6 reaches a certain position, it operates a first trip arm 4 (FIG. I) to cause resetting of the turnover mechanism'to an initial position in which a pair of lifting arms 5 and a pairv of rear arms 6 are stationed beneath the conveying run of the conveyor with the controls alerted for lift.
  • a first trip arm 4 (FIG. I) to cause resetting of the turnover mechanism'to an initial position in which a pair of lifting arms 5 and a pairv of rear arms 6 are stationed beneath the conveying run of the conveyor with the controls alerted for lift.
  • an additional arm 50 and an arm 60 is provided,adjustable laterally in positron.
  • arms 5, 6 are shown in the lowered position and are also shown, dot-dash lines in the raised position along with additional arms 5a, 6a.
  • arms 5 and 6 are swingable about a pivot 12 located below the conveyor with the arms 5 being downstream and the arms 6 upstream of the pivot 12.
  • Each arm 5 is provided with a bellcrank extension 5b pivotally connected to a link 14 which, in turn, is pivotally connectedto a link 13.
  • the link 13 is pivotally mounted intermediate its ends as shown at 13a and the freeendof the link, 13 is coupled to the piston rod 80 of a piston-'cyinder unit 8.
  • Each arm 6 is formed with an extension 6b which, via lever 11, is pivotally connected to the link 10 and the free end of the link I0 is connected to the piston rod.
  • the panel After having been turned over, the panel is transferred a second time over trip switch 7.
  • the trip 7 In order that the turnover mechanism is not reactivated, the trip 7 is rendered inoperative when the further trip is activated by the piston rod of the piston-cylinder unit 8 as previously described. Trip switch 7 is not reactivated until a further panel has arrived at trip arm 4.
  • a mechanism for turning over relatively flat articles having front and rear edges including a continuously movable conveyor for advancing articles, a pair of first lifting arms for lifting the front edge of each article upwardly from the conveyor, when such article reaches a predetermined point, to pivot.
  • said first lifting arms extending longitudinally of the conveyor and normally being positioned beneath the conveyor, pivot means for mounting the first arms for upward movement about an axis located upstream of the first arms, a pair of second arms for engaging the rear edge of the article on the conveyor for preventing sliding movement thereof in a direction in opposition to the direction of movement of the conveyor, said second arms extending longitudinally of the conveyor and normally lying beneath the conveyor, said second arms being mounted on said pivot means for upward rotation about the axis located upstream of the first arms support means for receiving the article operably related to the conveyor and above the conveyor for receiving the article when it overbalances about its rear edge, said lifting arms thereafter being lowered to control forward sliding movement of the rear edge of the article, and means operably connected with said first and second arms for effecting upward movement of said arms in synchronisr'n.
  • said means for effecting upward rotation of saidarms includes a pistoncylinder unit, and link means interconnecting said first and second arms with the piston rod of said piston-cylinder unit.
