摘要:
Preform gripper comprising a handling arm (1) and a preform support plate (2) that has at an extremity thereof a semi-circular aperture (7) that is adapted to accommodate a cylindrical portion (28) of the collar of the preform. Hinged on said plate there are provided two parallel side gripping members (5, 6), two end portions of which (13, 14) are in the shape of an arc of a circle and are adapted to elastically move closer to each other up to a pre-established position. The gripper is adapted to, enable said cylindrical portion (28) of the collar of the preform to be fitted into and removed from, with a snap-like action, said semi-circular aperture (7) by pressing and pulling, respectively, the preform against two opposite, elastically enlargeable outer edges (31, 32) of said two side gripping members (5, 6).
摘要:
An apparatus for continuously transferring orderly sequences of preforms includes a closed-loop conveyor belt and a plurality of support and forward carrying elements. A loading station is provided for loading the preforms, while an unloading station is provided for separating the preforms from the elements. A temperature conditioning station is provided between the loading station and unloading station.
摘要:
An injection mould component for moulding the outer surface of a preform neck, which allows improved cooling of the preform neck inside the mould, while at the same time reducing the mould cycle time. A related production process of said injection mould component, which allows the section of the cooling channels to be optimised, determining a more effective cooling, is also described.
摘要:
A conveying system for plastic material container preforms for conveying the preforms to a blow molding machine, comprising angular orientation systems for the containers with respect to a predetermined reference system, capable of orienting the preforms from the step of loading onto a conveying line to the step of blowing the containers in a blowing machine. A corresponding method of orienting the containers is further described, which may be implemented in this system.
摘要:
A process and device for drying the coating of containers made of thermoplastic material. The process involves feeding said containers through a furnace divided into two areas: in the first, most of the solvent of the coating is removed by heating the paint with infrared lamps, while the temperature of the containers is controlled through an airflow; in the second, the remaining solvent is removed using said airflow coming from the first area of the furnace.
摘要:
A gripping head (1) comprises a supporting element (11), e.g. a horizontal plate, adapted to rotate about a first rotation axis (&alpha,-) with which two or more grippers (12) are pivotally associated, so that each gripper is adapted to rotate about a symmetry axis (β) thereof, said rotation axes being parallel to each other, and being the rotation motion of each gripper independent from the others. Therefore, each gripper is adapted to rotate about a symmetry axis (β) thereof and revolve about the rotation axis (α) of the supporting element with which they are pivotally associated. A preferred plant, comprising said gripping head (1), comprises a belt conveyor and a mechanical limb (2) with which said gripping head (1) is pivotally associated.
摘要:
A device and process for extracting plastic preforms (5) from holders. Said device comprises a plate (23), which features straight slits (26) positioned parallel to each other, that is attached to a supporting table (20, 21). Each slit (26) comprises wider sections and constrictions (29, 30), which have a width (L2) smaller than the diameter of the ring (9) of the preform, so that the ring (9) can be fitted into the slit (26) through the wider section. The plate (23) is moved in the direction > by a specific length until the constrictions are positioned under the ring, and, thus, the preforms are removed by moving the plate away from the holders.
摘要:
A chuck (40) for quickly fastening and actuating container preforms (30) or plastic material containers to be used on conveying chains (4) of said preforms (30) or containers. The chuck (40) of the present invention is provided with particular expedients for allowing, for example, the angular orientation of the preforms from the step of loading onto a conveying line to the step of blowing the containers, in a blowing machine (9), in a simple, cost-effective manner.
摘要:
A plastic material container, e.g. a beverage bottle, having a neck which requires the use of a smaller amount of plastic than the bottle necks of the prior art, and which is able to ensure a complete functionality for coupling the cap, ensuring at the same time the possibility of implementing the traditional supporting; sealing and handling operations of the bottle carried out during the various steps of manufacturing the same.
摘要:
An apparatus for blow moulding of bottles in plastic material comprising a rotating turntable provided with moulds (4) on its outer circumference. Each mould (4) has three moulding forms (5, 6, 7) that can be controlled separately during the parison blowing operations so as not to blow those forms that may not have been supplied with parisons (12).
