Abstract: A positioning system of guide elements of a conveyor of articles comprises: at least one guide positioning unit comprising a guide positioning element adapted to be operatively associated with a respective guide element for the positioning thereof; a system of traction-transmitting cables operatively associated with the guide positioning unit, for transmitting traction forces; at least one traction unit associated with the system of traction-transmitting cables for exerting traction forces on the system of traction-transmitting cables. The guide positioning unit is either a driven guide positioning unit (133), wherein the guide positioning element is caused to be moved by the traction forces transmitted by the system of traction-transmitting cables, or a driving guide positioning unit, comprising a motor group associated with the guide positioning element.

Abstract: A supporting roller (12, 122, 123) that has a greater than usual capacity for constant operation comprises a skirt (14), for supporting a return side (16) of an endless chain of a chain conveyor, and, coaxial with the skirt (14), a hub (18) designed to rotate idly on a journal (19), and, in addition, a sleeve (20) made of a material having high friction laid over the skirt (14), in particular overmolded around the skirt (14) or slid axially onto the skirt (14).

Abstract: A conveyor chain for conveying products comprises a plurality of links, each link having a body defining a supporting surface for the products that are to be conveyed. Two adjacent links in the plurality of links are hinged to each other by a spindle of predetermined axis parallel to the supporting surface and extending between side projections of a first link and a central projection of a second link. The two adjacent links are articulated together by a hinge pin on a predetermined axis intersecting the axis of the spindle and perpendicular to the supporting surface. The spindle passes through the hinge pin which is rotatable in a seat formed in the central projection of the second link. A flat part is housed in a depression in the body of the second link, is rotatable about the axis of the hinge pin and is fastened axially to the body of the second link by retention means.

Abstract: A conveyor chain (1) for transporting articles, which has an unusually continuous bearing surface for the articles, comprises a plurality of links (2), in which each link defines a bearing surface (3a) for the articles to be transported, each link (2) being articulated to an adjacent link (2) in the chain by means of a pin (8) and being pivotable relative to the adjacent link (2) by means of a sleeve (11) which has an axis (Y-Y) perpendicular to the bearing surface (3a) and is rotatable coaxially about a pivot (13) fitted on the pin (8) and comprising a plate-like head (17) extending through the link (2) to the level of the bearing surface (3a) and having a portion (18) shaped like a segment of a circle with a base (18b) extending in the direction of the width of the conveyor chain, and a portion (20) having a side (20a) adjacent the base (18b) of the circular-segment-shaped portion (18) and an opposite side (20b) which is concave and fits the circular-segment-shaped portion (18) of the plate-like head (17) o

Abstract: A structure with idle rollers is intended for guide walls of goods conveyors comprising a surface for conveying the goods and at least one plate-like wall element extending longitudinally along the conveyor surface, adjacent to at least one of its edges, following its path. Roller-carriers each having a predetermined number of rollers mounted idly on axles and rotatable about rotation axes are snap-fitted on the plate-like wall element. The ends of the axles are supported by plates carried by the roller-carrier. The length of each roller-carrier depends on the minimum radius of curvature encountered in the path of the goods-conveying surface of the conveyor. The roller-carriers are connected to one another by snap-engagement members. The ends of the axles of the rollers are also snap-fitted in respective seats in the plates of the roller-carrier.

Abstract: A structure for a plate for receiving products as they come off a carry section of an endless chain-type conveyor, capable of being positioned coplanar with the carry section essentially in the continuation thereof, which structure is of unusually simple construction, comprising tiles arranged together side by side at least on respective sides that lie transversely to the carry section.

Abstract: A dividing wall for installation above a conveyor belt intended to convey articles such as bottles and the like, which allows conveying of the articles divided up into two flows in an easy manner and without obstacles and which is also suitable for construction on a large scale, comprises a plurality of idle rollers situated externally on each side of the wall.

Abstract: A link in a chain for conveying--in an unusually reliable manner--products such as containers, packets and the like in a given direction, comprises a link body with opposite side edges, a pin which is inserted through the link body and has head and tail ends supported in the side edges, and a plurality of rollers mounted so that they can rotate idly on the pin between the side edges, the head end of the pin being inserted in the corresponding side edge by means of a snap action.

Abstract: Fork-shaped links on a conveyor chain allow the chain to follow sharp curves in a right angle to the plane of the links as well as allowing oscillation of adjacent links in the same plane as the links. Each link has a crosspiece and a pair of arms. A seat of articulation and oscillation having a central narrowing is positioned on the crosspiece. The crosspiece is inserted between the arms of an adjacent link, and a pin having a longitudinal flattening is inserted with the flattened portion facing the central narrowing, through holes in the arm, and through the seat.
