APPLICATION UNIT AND METHOD FOR APPLYING A WALL TO A HOLLOW BODY IN A MANUFACTURING PROCESS FOR PRODUCING A BEVERAGE CAPSULE

摘要

Unit and method for applying a wall to a hollow body in a manufacturing process for producing a beverage capsule; are provided: a sealing conveyor which advances along a sealing path; a sealing head conveyed by the sealing conveyor and which supports a gripping device for gripping the wall and a retaining device suited to retain the hollow body; a first feed station for feeding the wall to the sealing head, so that the wall is gripped by the gripping device; and a second feed station arranged downstream from the first feed station along the sealing path, for feeding the hollow body to the sealing head, so the hollow body is coupled to the wall gripped by the gripping device, and is retained by the retaining device.

主权项

1. An application unit (10; 12) for applying a wall (3; 4) to a hollow body (2) in a manufacturing process for producing a beverage capsule (1); the application unit (10; 12) comprises:
at least one sealing conveyor (13; 54) which advances along a sealing path; at least one sealing head (15; 56) conveyed by the sealing conveyor (13; 54) and supporting a gripping device (16; 57) suited to grip the wall (3; 4) for advancing the wall (3; 4) along the sealing path; and a first feed station (18; 59) for feeding the wall (3; 4) to the sealing head (15; 56), so that the wall (3; 4) is gripped by the gripping device (16; 57); the application unit (10; 12) is characterized in that: the sealing head (15; 56) comprises a first retaining device (17; 58) suited to grip the hollow body (2) for advancing the hollow body (2) along the sealing path; a second feed station (19; 60) arranged downstream from the first feed station (18; 59) along the sealing path, for feeding the hollow body (2) to the sealing head (15; 56) is provided, so that the hollow body (2) is coupled to the wall (3; 4) gripped by the gripping device (16; 57), and is retained by the first retaining device (17; 58); and the sealing head (15; 56) comprises an annular sealing member (25; 66) surrounding the gripping device (16; 57) and movable between a rest position, in which the sealing member (25; 66) is detached from the wall (3; 4) gripped by the gripping device (16; 57), and a work position, in which the sealing member (25; 66) contacts the wall (3; 4) gripped by the gripping device (16; 57), on the opposite side to the hollow body (2); the sealing member (25; 66) being maintained in the rest position at the feed stations (18, 19) and being moved into the work position downstream from the second feed station (19; 60).
