Abstract: A machine for packaging groups of tissue products including a dosing element equipped with a plurality of passageways each configured for receiving a row formed by a predetermined number of products for defining a layer of a group of products. A detection device associated with the dosing element detects a filling parameter relative to a number, dimension and/or orientation of the products occupying the passageways and generates a signal representing the filling parameter. A processing and control unit receives the signals representing the products and processes the signals to compare with signals relating to a reference layer for deriving an acceptance condition, wherein the layer is consistent with the reference layer and suitable for the packaging, or for eliminating the layer of products released from the dosing element. A rejection system ejects the layer when it is in the eliminating condition.

Abstract: Unit for packaging and palletizing rolls of paper comprising a bagging and/or forming machine adapted to sort packages of said rolls into batches or to bag said sorted loose packages in a plastic bag, and a palletizing station comprising at lease one manipulator provided with grippers to handle loose packages of delivered products from said bagging and/or forming machine. The products are conveyed to said palletizing station with a predetermined stepped sequence and spaced from one another in at least one row on a conveyer element, wherein said at least one robot and said bagging and/or forming machine are interconnected and are programmed respectively to sort said products in batches of different forms and dimensions according to a sequence which is continuously variable to form a layer of a pallet with different batches of products adjacent to and engaged with one another.

Abstract: A unit for packaging and palletizing rolls of toilet paper and/or kitchen towel comprising a bagging and/or forming machine (20), suitable to sort several packages containing a plurality of rolls, called loose packages (11) into batches (12), and optionally to bag said sorted loose packages (11) in a bag (13), and a palletizing station (30) with at least one robot (31) provided with grippers to handle batches (12) of sorted products composed of loose packages (11) or of a bag (13), wherein the batches (12) delivered from the bagging and/or forming machine (20) are conveyed to the palletizing station (30) with a predetermined stepped sequence and spaced from one another in at least one row on a conveyer element (21), wherein the robot (31) and the bagging machine (20) are electronically interconnected and are programmed respectively to sort and handle the products in batches (12), loose packages (11) or bags (13), of different forms and dimensions according to a sequence, continuously variable in a predetermin

Abstract: A method for stopping and restarting an automatic machine (1) for wrapping products (2), in particular rolls of toilet or kitchen paper, in a collective pack (3) using a packaging film (4a) unwound from a first reel (31a). The method comprises the following automatic sequence of steps: reducing the speed of the machine (1); and stopping the feeding of the products (2) and of the film (4a) at suitably synchronized intervals from each other relative to the processing of the products (2). The method subsequently comprising the steps of: substituting the first reel (31a) of the film (4a) with a second reel (31b); loading the film (4b) on the second reel into feed means (33, 10 34). Restarting the machine (1) at reduced speed and thereby automatically activating the following sequence of steps: unwinding and positionally centering the film (4b); and restarting the feeding of the products (2) and of the film (4a) at suitably synchronized intervals from each other relative to the products.
