Title: Improvements in or relating to packing machines
IPC: B65B21/18
Filed: 1949-03-07
Abstract: 665,138. Packing-machines. HILL, R. J. June 7, 1950. [March 7, 1949] No. 6167/49 Class 94(i). [Also in Group XXX] In a machine for inserting bottles into a packing case, the bottles are conveyed into the machine and then displaced laterally from their path of movement into a receiving device which supports them against relative downward movement, the receiving device being then operable to lower the bottles gently into a row of case compartments, whereafter the lowered bottles are freed from the device. As shown, cases comprising twelve compartments arranged in three rows of four are fed into the 60 machine by an endless conveyer 1 arranged at right angles below an endless bottle conveyer 2, the conveyer 1 being driven from the conveyer 2 through gearing which also drives through a clutch 34 a camshaft 64. As a case is moved to the right by the conveyer 1 it engages and swings aside a lever 71 which operates through linkage to engage the clutch 34. A cam 62 on the shaft 64 then operates through linkage to cause rods 47 to descend into the first row of case compartments and prevent movement of the case with the conveyer 1, and a second cam 67 (not shown), operates a transversely-movable control rod 25 to allow four bottles to pass intothemachine. A third cam 43 then operates a pusher 36 which moves the four bottles transversely into .a receiving device 4 constructed by a plate mounted for vertical movement in guides 80, under the control of a fourth cam 66 (not shown), and formed with notches 45 terminating in semi-circular recesses which engage under the enlarged portions of the necks of the bottles. The bases of the bottles are temporarily supported by a hinged platform 44 which is coupled to the plate 4 so as to be swung to the vertical position as the plate is moved downwardly to lower the bottles into the case compartments. After the first row of compartments has been filled, the rods 47 rise, thus allowing forward movement of the case to free the bottles from the plate 4, and then descend into the second row of compartments, the plate 4 and pusher 36 are returned to their initial positions and the filling operation is repeated. After the third row of compartments has been filled, the case moves clear of the lever 71 which swings back and disengages the clutch 34. The conveyer 2 is associated with a spring- loaded plate 26 mounted on a lever 27 which is coupled through linkage to the lever operating the clutch 34, the arrangement being such that if the feed of bottles is interrupted, the plate swings across the conveyer and disengages the clutch.
