APPARATUS MOLDING SHOE SOLE ONTO SHOE LEG

摘要

A system for moulding soles onto shoe legs comprises a rotatable moulding table (1) with locations (1a, 1b, 1c, 1d) for a plurality of lasts (40) and an endless conveyor (6) situated next to the table and on which lasts (40) can be mounted and dismounted. A robot (70) is present between a second transfer station (10) on the moulding table (1) and a first transfer station (60) on the conveyor (6). This robot transfers lasts (40) provided with shoe legs from the first transfer station (60) to the second transfer station (10) and later on from the latter back to the first transfer station (60). Last holders (30) are mounted above the individual last locations (1a, 1b, 1c, 1d) of the moulding table and as an integrating part of the moulding table (1). These last holders are adapted opposite the second transfer station (10) to receive and retain the individual lasts (40) and later on - when the last holder (30) has followed a 360 DEG rotation of the moulding table (1) and returns to the second transfer station (10) - to release the last (40). The conveyor (6) is adapted to advance a plurality of conveyor plate members (80) carrying the individual lasts (40), and these conveyor plate members are adapted opposite the first transfer station (60) to release and receive, respectively, the lasts (40) transferred by the robot (70). Each last (40) comprises at the top a gripping plate member (41) adapted to be gripped and retained by the robot (70) in an exact manner and to be fixed on the conveyor plate members (80) or on the last holders (30). In this manner an essential reduction of the measure time of the moulding table is allowed, preferably by up to 33%, and the system is suited both for shoe lasts and boot lasts.
