Abstract:
An apparatus for placement of angle plates (5) including arms in transverse ventilation duct (3) flanges (7) said apparatus comprising:a blocking device (2) attached to a platen, said blocking device to secure the ventilation duct (3) on the platen,a feeding device (4) including a slider (10), said feeding device to transport said angle plates, said slider (10) being stably joined to a piston-rod (15) of a cylinder (16) to move freely along a guide bar (25),a supply hopper (11) to house said angle plates (5) located above said feeding device (4),a fastening device (6) to fasten said angle plates (5) in said flanges (7) of said ventilation ducts (3) anda clamping device (8) to clamp the flange (7) edges on said angle plates (5),characterized bysaid feeding device (4) to move said angle plates (5) comprising a movable double arm carrier (9) located on a base plate (19),said guide bar (25) being located in a lower part of the base plate (19) and on a working plane (14) of the slider (10), said base plate (19) having a port (23) shaped substantially as one of said angle plates (5) and an oblong hole (21), said slider (10) having an oblong slot (12) and a socket (13),a carrying pin (20) being joined to said carrier (9) and extending through the oblong hole (21) into the oblong slot (12), so that the carrier (9) is shifted by said slider (10) after each movement of said slider (10), said slider (10) working plane (14) having a furrow (26) whose width is smaller than a span of said arms of said angle plates (5),a guide (24) being secured to a front part of said base plate (19) above the furrow (26), such thatupon backward movement of said carrier (9), the lowest angle plate (5) stacked in the supply hopper (11) is caught by the arms of said carrier (9) and transported to said port (23), whereupon a respective angle plate (5) drops through the port (23) onto the slider (10) working plane (14), and upon forward movement of said slider (10), the socket (13) reaches the corner of the angle plate (5) so as to move the angle plate (5) on the slider (10) working plane (14) towards the ventilation duct (3), whereby the corner of the angle plate (5) reaches said guide (24) thereby causing the rising of said angle plate (5) arms.
