Abstract:
A machine (1) for packing a tile or a stack of tiles (5) with one or more cardboard blanks (3), comprising: a first store (2) containing cardboard blanks (3); a folding station (4) for folding a cardboard blank (3) against a tile or a stack of tiles (5); transfer means (6) for transferring a cardboard blank (3) from the first store (2) to the folding station (4) along a pathway; a printing head (7) arranged along the pathway and activated in phase relation with the transfer means (6) such as to print on the cardboard blank (3) when the cardboard blank (3) is positioned along the pathway between the first store (2) and the folding station (4).
Abstract:
The device for positioning a protecting element (S) at a corner of a stack of tiles to be packed comprises a frame (1), positionable by a flank of the conveyor line (L) of the stacks (P) of tiles towards a packing station, and between the line (L) and a store (M) for containing the protecting elements. The device (D) comprises pick-up means (2) activatable for picking up a protecting element (S) and deactivatable for subsequent release of the protecting element (S), a support element (3) for supporting the pick-up means (2), which is constrained rotatably to the frame (1), and actuator means (4, 41, 42) for rotating the support element (3) with respect to the frame (1). The actuator means (4, 41, 42) are activatable for rotating the support element (3) in such a way a to position the pick-up means (2) facing towards the store (M) for picking up a protecting element (S) and, after the protecting element (S) has been picked up by the pick-up means (2), activatable for rotating the support element (3) such as to position the pick-up means (2) facing towards a corner of the stack (P) of tiles paused on the line (L), in order to enable release of the protecting element (S) at the corner.
Abstract:
The invention relates to a method for scanning a coloured surface (2) of a tile and a device which actuates the method. The device (1 ) for scanning a coloured surface (2) of a tile (3) comprises a matrix of photodetectors (4) comprising a plurality of rows of photodetectors (5) which are parallel and placed side by side, the matrix of photodetectors (4) does not comprise any colour filter above the photodetectors (4) and the rows of photodetectors (5) are near each other and spaced by a distance equal to at least one pixel; the matrix of photodetectors (4) is arranged such as to acquire, in synchrony with a temporal scanning interval, an image of a surface band (6) of a coloured surface (2) to be scanned of a tile (3). The device also comprises: a plurality of lamps (7) each having a light emission spectrum different from a light emission spectrum of another lamp of the plurality of lamps (7); the lamps of the plurality of lamps (7) being arranged such as to illuminate the surface band (6) of the coloured surface (2) to be scanned of the tile (3); the lamps of the plurality of lamps (7) being commandable to switch on at least one at a time at each temporal scanning interval; conveyor means (8) provided for restingly receive and transport the tile (3) to be scanned and for determining a relative movement between the tile (3), on a side, and the matrix of photodetectors (4) and the plurality of lamps (7), on the other side, in a movement direction which is perpendicular to the plurality of rows of photodetectors (5) such that for each surface band (6) of the coloured surface (2) to be scanned of the tile (3) a predetermined number of images is acquired.
Abstract:
A device (1) for stabilizing a mutual gluing of flaps of one or more cardboard blanks (41, 42) applied to a tile or stack of tiles (2), a tile or stack of tiles (2) comprising an upper surface (3) and a plurality of flanks; one or more cardboard blanks (41, 42) being applied to the tile or stack of tiles (2) and comprising a first flap (21) and a second flap (22) which are folded against the upper surface (3) of the tile or stack of tiles (2), the first flap (21) and the second flap (22) being superposed on one another at a first superposing zone (31), the first flap (21) and the second flap (22) being glued to one another at the first superposing zone (31). The device (1) comprises: a seating (13) for restingly receiving the tile or stack of tiles (2) which has been packed with the one or more cardboard blanks (41, 42); a first metal band (14) which: is fixed to the frame (9); is elastically flexible; is arranged above the seating (13) such as to elastically press against the first superposing zone (31) when a tile or packed stack of tiles (2) is in the seating (13), stabilizing the mutual gluing of the first flap (21) and the second flap (22); and conforms a lead-in for facilitating inserting by dragging of the tile or stack of tiles (2) packed into the seating (13).
