Abstract:
The invention concerns a mold-carrier unit for a thermoplastic container blowing machine. The mold-carrier unit is designed to equip a machine for making containers obtained by blow-molding, and optionally by elongation, based on a thermoplastic preform. The unit comprises at least one rotatable mobile panel (3, 5), bearing articulating lugs on a first edge and bearing locking lugs (17, 15) on a second edge, the mobile panel including at least one rib (31, 33, 39; 41, 45, 49) enabling at least one locking lug to be connected with at least one articulating lug such that the rib reinforces the rigidity of the mold-carrier unit.
Abstract:
The invention relates to a device for conveying vessels of the bottle type, characterised in that it comprises: a primary wheel for conveying the bottles including a plurality of transfer arms; at least two secondary conveying wheels respectively capable of conveying the bottles fed by the primary wheel; the conveying path of the bottles grasped by the clamps of the transfer arms of each secondary wheel being at one point tangential to the conveying path of the bottles grasped by the transfer arms of the primary wheel, whereby the main flow of bottles conveyed by the primary wheel is divided into at least two secondary flows of bottles respectively conveyed by the secondary conveying wheels.
Abstract:
A molding device for blow molding recipients made of a thermoplastic material, including a mold having two mold halves which are movable with respect to each other and provided with a locking device extending along the total height of the mold halves and including two respective hooks, which are oriented toward each other, two respective recesses adjacent to the hooks and a rotatable gib adjacent to the hook and interacting with the other hook in such a way that the two mold-halves are locked in the closed position thereof or are released from each other, the gib being inserted into the recess.
Abstract:
A device for blow molding or blow drawing of containers made of thermoplastic performs. The molding device is movable, mainly rotatable and includes at least one wallet-type mold provided with two mold-halves rotatable with respect to each other around an axis; two links which are connected to each other by one of the extremities thereof with the aid of a first pivot pin and pivotally connected to two mold-halves by the other extremities thereof on both sides of the common pivoting axis thereof; actuation devices which are connected to the first pivot pin and provided with at least one cam follower interacting with at least one respective fixed cam so that the first pivot pin is moved in a direction toward the mold or away therefrom, thereby opening or closing the mold. A compensating device acts so that at least one cam follower permanently contacts the respective cam.

Abstract:
The invention provides a cooling system for cooling a rotary mount (2) comprising two rings (4, 7) capable of rotating relative to each other, each ring having a raceway, the mount further comprising a bearing device constituted by rolling bodies interposed between the two raceways, the cooling system being characterized in that it comprises at least one circuit for passing a cooling fluid, which circuit is pressed against one of the two rings (4, 7) of said mount. It also provides a rotary mount including such a system, and a machine, in particular a blow-molding machine, including such a mount.
Abstract:
Device (1) for switching containers rotating about a fixed axis (10) of rotation and comprising, arranged peripherally around the axis (10) of rotation, a plurality of arms (7, 188) for gripping at least one container, each gripping arm (7, 188) comprising a cam follower (98, 186) for engagement in a cam raceway (91, 184), the raceway (91, 184) comprising at least one fixed section (111, 112, 115) and at least one removable section (120a, 120b, 194, 196) for a retractable cam, said device being characterized in that it comprises at least one rotary transverse plate (152, 153, 185) on which are fixed the radially mobile gripping arms (7, 188) and at least one fixed transverse plate (90a, 90b, 182) containing the raceway (91, 184) of the cam follower (98, 186) of the gripping arm (7, 188), and in that the removable section (120a, 120b, 194, 196) is retractable in a direction approximately parallel to the axis (10) of rotation by means of an actuator (140a, 140b) mounted on the fixed transverse plate (90a, 90b, 182).
