ABSTRACT:
A selectively adjustable apparatus permits the holding down and stabilizing of cartons in a continuous motion packaging machine as grouped articles are inserted into the cartons. The apparatus includes a pair of spaced parallel hold-down rails (56, 62) adapted to engage the tops of moving cartons with light force to hold the cartons down and inhibit their deformation as grouped articles are inserted with significant momentum into the cartons. A side rail (97) is provided and positioned to engage the back ends of the moving cartons to absorb the momentum of grouped articles as the articles are inserted into the cartons. A system of vertical and horizontal guide rails (38, 39, 46, 47, 57, 58), sliding guide blocks (41, 42, 48, 49, 63, 64), brackets (43, 44, 51, 52, 66, 67), and actuators (32, 73, 74) provides for rapid and accurate adjustment of the vertical positions and spacing of the hold-down rails and the transverse position of the side rail and rear hold-down rail to accommodate cartons of virtually any size. Thus, the apparatus can be reconfigured quickly, accurately, and reliably to accommodate a change in carton size necessitated by a change in article size or article group configuration without breakdown and without the resources of a trained technician.
