| 摘要 |
The present invention relates to the sector of automatic plants for filling containers or in particular bottling plants, in the form of a safety device in aligning machines of the type comprising a cylindrical hopper (2) rotating about a vertical axis (3), a fixed conical structure (5) and a plurality of hoists (6), each operated by an operating arm (8). Each operating arm (8) in an original manner is formed by means of at least two sections (8a, 8b) which are connected together by means of a hinge connection (10) so as to rotate with respect to each other in the event of jamming of the corresponding hoist (6). Moreover, the sections (8a, 8b) comprise means (11) which are designed to keep said sections in the working or thrusting position of the operating arm (8) until a threshold resistive force is exceeded.
