Abstract
The guide structure for stoppers takes the form of a tunnel with a C-shaped section for trapping and guiding the cylindrical part of the stoppers (1c, 1t), which tunnel has opposing edges spaced out at a distance such as to allow the passage of the bulge (3) of the nipple-type stoppers (1t). This structure consists of filamentary rails (5) and of plates (6) with a hole through their central part shaped according to the profile of the stoppers that are to be transferred.
Claims8
A guide structure for stoppers with or without a teat, said structure being in the form of a tunnel able to enclose and guide a cylindrical part of said stoppers, said tunnel comprising, firstly, mounting plates located transversely with respect to the running direction of said stoppers in said tunnel and distributed regularly over its length, and, secondly, rails which extend from its inlet as far as its outlet, said rails being fastened on the contour of a central passage cut through the mounting plates and being divided into a plurality of groups:
- thread-like rails which act as a slideway for guiding the large flat surface of the cylindrical part of the stoppers,
- thread-like lateral rails which flank said cylindrical part of the stoppers,
- closing rails for closing said tunnel, which engage with the annular flat surface of said cylindrical body of the stoppers and which are spaced apart by a distance D corresponding at least to the diameter of the protuberance of the stoppers having a teat, in order to flank this teat;
- wherein the closing rails have a polygonal section, of which an edge forming a guide surface is flat and located in a plane parallel to that of the slideway formed by the thread-like rails.
