摘要:
A machine for the continuous surface decoration of products, particularly ceramic tiles, comprises a frame (3) that supports a substantially horizontal portion of a product conveyor (4), above the upper active portion of which a decorating drum (5) is mounted which has a horizontal axis (A) arranged transversely to the direction of advancement of the conveyor (4); the drum (5) is supported by the frame (3) in a slightly raised position, without contact with the surfaces of the products (2) to be decorated; the perimetric surface (5a) of the decorating drum (5) is perforated according to a design for the passage, from the inside outward, of glazes propelled by a stream of gaseous fluid ejected under pressure from the end portion (6) of a corresponding ejector (7) located inside the drum (5) at the decoration region.
摘要:
The apparatus for synchronized supply of ceramic tiles to a rotary glazing and decorating machine comprises a distribution and presynchronization device (6) positioned upstream of a conveyor belt (4) on which a matrix-bearing cylinder (1) operates. The distribution and presynchronization device (6) singly positions the tiles on the conveyor belt (4) in accordance with a relative position of a matrix predisposed on the matrix-bearing cylinder (1). A synchronization apparatus varies by a predetermined time a rotation speed of the matrix-bearing cylinder (1) in accordance with a perceived position of a tile (2) arriving below the matrix-bearing cylinder (1).
摘要:
A method for applying a pattern (21,57) of granular material (12, 12b, 12c, 12d) on a receiving surface (13), comprising in sequence associating said granular material (12, 12b, 12c, 12d) with a transferring surface (3) together with a liquid aggregating phase (9, 20) and according a prefiguration (10, 10b, 18, 56) of said pattern; facing said transferring surface (13) in a transferring zone (15, 45); the method further comprises heating at least one portion of said liquid phase (9, 20) in said transferring zone (15) in order to detach from said transferring surface (3) said granular material (12, 12b, 12c, 12d) and applying the latter on said receiving surface (13). An apparatus (1, 1b) for applying a pattern (21, 57) of granular material (12, 12b, 12c, 12d) on a receiving surface (13), comprises: a transferring surface (3) movable along a loop path with a transferring zone (15) defined in a portion facing said receiving surface (13); applying means (8, 8b, 11, 11 b, 11c, 11 d) arranged upstream of said transferring zone (15), suitable for applying said granular material (12, 12b, 12c, 12d) on said transferring surface (3) together with an aggregating liquid phase (9) and according a prefiguration (10, 18, 56) of said pattern (21, 57); the apparatus further comprises heating means (16, 25, 26, 46, 47, T) suitable for suddenly evaporating in said transferring zone (15) at least one portion of said aggregating liquid phase (9, 20) and thus cause said granular material (12, 12b, 12c, 12d) to detach from said transferring surface (3) and to cause said applying on said receiving surface (13).
摘要:
The invention relates to a printing table assembly (1), comprising at least one printing device (2) for imprinting substrates (22, 24, 31) and at least one printing table (5), which comprises a first transport device (7) for transporting the substrates (22, 24, 31) to be imprinted in a first plane (9) and a lifting device (11) for moving the first transport device (7) with the first plane (9) between a printing plane (13) associated with the printing device (2) and a transport plane (12) located beneath. For this purpose, the printing table (5) comprises a second transport device (8) for transporting the substrates (22, 24, 31) in a second plane (10) beneath the first plane (9), wherein the fixed distance (A) between the first plane (9) and the second plane (10) corresponds to the distance (A) between the printing plane (13) and the transport plane (12). The invention further relates to a method for operating a printing table assembly.
