Abstract

A reel unwinder including a first unwinding position, in which a first reel is positioned; a second unwinding position, to which the first reel is transferred when it is replaced with a second reel; a stand-by position, in which the second reel is kept in stand-by; a first unwinding member adapted to start rotation of the second reel when the first reel is replaced with the second reel. Moreover, the unwinder includes a second unwinding member, with at least one endless flexible element. The endless flexible element extends from the first unwinding position to the second unwinding position, and is adapted to maintain the first reel in contact with the second unwinding member and in rotation by the second unwinding member in the first unwinding position, in the second unwinding position and while it is being transferred from the first unwinding position to the second unwinding position.

Abstract

A device for launching products into a feeding path, including a launcher; a detection sensor to detect the passage of products launched by the launcher; a launcher central control unit; conveyors to move forward the products in the feeding path, associated with a drive member; and at least one movement sensor to detect the position of the products moved by the conveyors. The central control unit is programmed to control the start position taken by each group of products, downstream of the detection sensor, and to impose on each group of products a forward movement according to the length of the group of products and to an adjustment factor determined by the error, if any, between the detected start position and a desired start position.

Abstract

The packaging machine comprises: an insertion station (3) for inserting the rolls in wrapping sheets (I); a feed path (P) of the rolls (R); a conveyor (11) for feeding the rolls (R) along the feed path (P); a folding station adapted to be equipped alternatively with different types of folding members, as a function of the type of pack to produce.

Abstract

A device for launching products into a feeding path, comprising: a launcher (1); a detection sensor (23) to detect the passage of products launched by said launcher; a launcher central control unit (9); conveyors (3 A, 3B) to move forward the products in said feeding path (11), associated with a drive member (7); and at least one movement sensor (7 A) to detect the position of the products moved by said conveyors (3A, 3B). The central control unit is programmed to control the start position taken by each group of products, downstream of the detection sensor, and to impose on each group of products a forward movement according to the length of the group of products and to ad adjustment factor determined by the error, if any, between the detected start position and a desired start position.
