摘要:
A furnace for the continuous heat treatment of glass containers, comprising a structure (12) provided with a conveyor (13) which is designed to receive containers (31, 131, 231) and which is made to advance through a hot zone (14) and a ventilated zone (15), said conveyor (13) comprising a pair of chains (17) which are located on opposite sides of the structure (12) and which are wound in an endless loop onto toothed end pulleys (18) so as to define an upper conveying section and a lower return section, links in each of the chains (17) having a plurality of brackets (21) which are arranged in a projecting manner and are directed inwards towards the opposite parallel and adjacent chain (17), said brackets having, mounted on them, cross-pieces (22) provided with a plurality of supports (28) on which at least a portion of the containers may rest.
摘要:
A device for the movement and positioning of an object in space comprising at least one base element (12), at least one movable element (30), at least three articulated composite arms (17, 117; 18, 118; 22, 122) assembled by means of joints which connect the at least one base element (12) and the at least one movable element (30) by means of further joints, at least three rotational actuators (13, 14, 19) each of which is operatively connected to activate one of the three arms (17, 117; 18, 118; 22, 122), wherein at least one differential (23), provided with at least two inputs (15 and 16) and at least one output (24) is arranged so as to operate between two of the above actuators (13, 14), the output (24) of the differential moving the motor (19) by means of a transmission (25) and the above arm (22, 122) by means of a support (26) rotatingly supported around an axis (20) with respect to the base element (12), the arm (22, 122) being arranged so as to oscillate in a plane orthogonal to a plane in which the first two arms (17, 117; 18, 118) oscillate.
摘要:
A device for correct axial positioning of semi-finished glass vials, wherein the vials (11) have a formed mouth and a semi-finished bottom and are held by supporting elements (17), comprises an actuator unit (20) for at least one gauge element (21) of the mouth of the vials (11) and a mechanism to reduce the load (22) of the supporting element (17) with synchronous action in relation to the actuator unit (20), said supporting element (17) being at least one and being constituted by gripping elements which grip the body of the vial (11).
摘要:
A centring device for a semi-finished glass vial in a machine for the continuous forming of glass vials or containers wherein the machine is provided with a rotary carousel (14, 15) with a plurality of supporting elements (17) equipped with gripping element (18) for glass tubes (22) passing through them, wherein the device comprises at least one stable positioning element (23, 31) of at least one supporting element (17) and a centring pin (35) of a free end (12a) of the glass tube (12), the at least one stable positioning element (23, 31) and the centring pin (35) being mechanically interconnected to move between an engaged position and a disengaged position with the at least one supporting element (17). Preferably, there are two stable positioning elements (23, 31) which act on the two supporting elements (17), and two centring pins (35) of two free ends (12a) of a pair of glass tubes (12).
