A plant for making containers of thermoplastic material in continuous cycle comprises: a rotary molding machine (1) configured to make parisons (2) of thermoplastic material having a body (3) with a closed bottom and a neck (4) which defines an opening; an oven (5) for heating the parisons (2), connected to the molding machine (1) and equipped with heating means (6) operating on the body (3) of the parisons (2); a rotary blow-molding machine (7) configured to receive the parisons (2) heated in the oven (5) and to blow-mold them in molds (8) to make the containers; and a management unit (9) for the plant (10), configured to switch off the oven (5) heating means (6) during a shutdown period of the blow-molding machine (7) but without interrupting the operation of the molding machine (1), so as to enable the parisons (2) located in the oven (5) to cool down during their transit through the oven (5).
摘要:
A compression-forming apparatus is disclosed comprising a plurality of forming units arranged on a rotating carousel, wherein each forming unit has a first half unit that carries the object to be compression-formed and is connected to an auxiliary member by a motion multiplying rocker, so that a movement of the auxiliary member by a certain amount is matched by a movement of greater amount of the first forming half unit; in use, the auxiliary member is moved by a cam follower coupled with a first cam profile to have an initial very fast closing step of the forming unit without compression force, after which a compression force is generated that is discharged on a second cam profile by another cam follower associated with the first forming half unit.

An inspection method (2) is provided for inspecting a sheet in a press (1), wherein the press (1) comprises a punching unit (4) which is suitable for receiving a sheet (2) provided with a plurality of printed portions (3) arranged in a regular manner according to a printing pattern and for cutting the sheet in dwell steps thereof, separating into several steps a plurality of printed discs. The method comprises: - providing abutting means (22, 23, 24) arranged upstream of the punching unit (4) to receive the sheet (2) to be cut and adjust the position of the sheet (2), - advancing in a first direction (Dl) the thus adjusted sheet (2) to the punching unit (4) to obtain the plurality of printed discs; - processing at least one acquired image of the sheet (2) to detect an arrangement of the printing pattern in the sheet (2); - comparing the detected arrangement of the printing pattern with a nominal arrangement of the printing pattern to obtain a shift of the printing pattern in the sheet (2) with respect to said nominal arrangement; - acquiring at least one image of the sheet (2) upstream of the abutting means (22, 23, 24) during advancement of the sheet (2) in a second direction (D2). To detect said arrangement of the printing pattern the method further comprises: - identifying a top edge (2a), a bottom edge (2b) and a side working edge (2c) of the sheet (2) and further identifying a top graphic mark (20), which is arranged in a top corner (18) defined between the top edge (2a) and the side working edge (2c), and a bottom graphic mark (21) which is arranged in a bottom corner (19) between the side working edge (2c) and the bottom edge (2b); - calculating a longitudinal shift and a top side shift of the top graphic mark (20) and a bottom side shift of the bottom graphic mark (21); and wherein said adjusting the position of the sheet (2) in said abutting means (22, 23, 24) comprises translating and/or rotating said sheet (2) as a function of said longitudinal shift, and/or said top side shift and/or said bottom side shift to position said printing pattern in said nominal position so as to obtain in said punching unit (4) printed discs in which each printed portion (3) is arranged in a desired position.
摘要:
A method and an apparatus for forming annular doses provides a flow of plasticised material supplied by an extruder which passes through a channel that is first cylindrical and then annular. The material exits from an annular outlet in front of which a cutting element passes that separates an annular dose of material. The dose is deposited on a surface of a capsule having a capacity to adhere to the dose that is greater than the cutting element. The surface and the cutting element are distanced from one another in such a manner that the annular dose remaining adhering to the capsule is detached from the element. Detachment can be promoted by a flow of air.
