Printing facility for the manipulation of a plurality of sleeve assemblies (52) each composed by a printing sleeve (50) having a cylindrical internal surface (61) with a diameter larger than the diameter of a printing shaft (12) and an independent tubular cylindrical intermediate sleeve (51) inserted into the cylindrical printing sleeve (50), said printing sleeve comprising a printing machine (10) comprising cylindrical printing shafts (12), and a robotic unit (20) comprising a sleeves handling device (21), the facility further comprising a first storage (30) for store a plurality of printing sleeves (50), which include retaining elements (31) for the immobilization of the stored printing sleeves (50) in geometrical interference with the printing cylindrical external surface (60) and/or with at least one of the annular faces (62) of the printing sleeves (50).

A screen provision system, for a printing device with a screen receptacle for a printing screen-and a squeegee device associated with the screen receptacle, has a conveying device for conveying a printing screen and at least one screen magazine with multiple screen storage portions that can each receive a printing screen. The screen provision system has at least one treatment station for treating the printing screens. The conveying device supplies printing screens to the screen magazine and to the at least one treatment station.

An apparatus for replacing printing sleeves comprising a handling device which can be removably engaged with a printing sleeve and a movement robot for moving the handling device; the handling device comprises a supporting frame, which is connected to the movement robot and supports a supporting rod which protrudes in a cantilevered manner from the supporting frame, and a grip assembly which is able to translate on command, with respect to the supporting frame, along a movement direction that is substantially parallel to the axis of the supporting rod, between an advanced working position and a retracted working position; the grip assembly is actuatable in rotation about an axis that is substantially parallel to the axis of the supporting rod.

An apparatus for replacing printing sleeves which comprises a handling device which can be removably engaged with a printing sleeve and a movement robot for moving the handling device; the handling device comprises a supporting frame and a self-centering grip clamp which is able to translate on command, with respect to the supporting frame, along a movement direction that is substantially parallel to the axis of the supporting rod, between an advanced working position and a retracted working position; the grip clamp has engagement elements which are movable on command between an inactive position and an active position, in which they are radially spaced apart from the axis of the supporting rod, in order to allow their engagement with the internal surface of the printing sleeve.

A cover of a stencil printer is hingedly mounted to a frame, and movable between a closed and open positions. The cover includes an elongate opening formed therein and a movable door configured to selectively close the elongate opening. The elongate opening is sized to enable the stencil and/or a tooling tray to pass through. A controller is configured to control movement of the movable door between a closed position and an open position. A sensor assembly is proximate the elongate opening. The sensor assembly is coupled to the controller and configured to detect an object within the elongate opening when moving the movable door to the closed position. The sensor is configured to generate a signal to the controller when detecting an object within the elongate opening. The controller, upon receiving the signal from the sensor, is configured to move the movable door to the open position.
