摘要:
An injection blow molding system includes an injection molding station (22), a first delivery section (24), a cooling station (26), a heating station (30), a second delivery section (32) and a plurality of blow molding stations (34). The station (22) simultaneously injection molds M rows of N preforms (36) arranged in a second direction (B) perpendicular to a first direction (A) in which the preforms (36) are carried. The first delivery section (24) removes the M rows of preforms (36) using a removing mechanism (102) in their upright state while decreasing the pitch in the rows. The preforms 36 are inverted with the column pitch changed by an inverting mechanism (104) before delivery to the cooling station in their inverted state. The cooling and heating stations (26), (30) cool and heat one row of N preforms (36) while parallel carrying them along a first carrying chain (200). The second delivery section (32) delivers the preforms (36) to two blow molding stations while in their inverted state. Each blow molding station (34) stretch blow molds the N/2 preforms into containers at the same time.

A heat blow molding apparatus includes a supply section 110, a heating station 112, a transfer section 114 and a blow molding station 116, all of which are disposed linearly in a direction A in which preforms 118 are carried. The supply section 110 supplies the preforms 118 each having a neck portion in their inverted state. The heating station 112 simultaneously heats the inverted preforms 118 while they are being carried parallel to each other. The transfer section 114 transfers the inverted preforms 118 after they have been heated by the heating station. The blow molding station 116 simultaneously blow molds the inverted preforms 118 transferred from the transfer section 114 into containers.
摘要:
A heat-resistant container molding apparatus and method which are compact and inexpensive and can reliably increase the crystallinity, reduce the residual stress in a container filled with a hot content such as thermally sterilized fruit juice, and prevent a thermal deformation with improved container stability at a raised temperature. The apparatus has a receiving and removing unit for receiving primary moldings obtained by blow-molding preforms and for removing final products, a heat treatment section for heating the primary moldings by bringing the primary moldings into contact with the inner wall of a heat treatment mold while pressurizing the interior of the primary moldings within the heat treatment mold, a final molding section for blow molding intermittent moldings into final products within a final blow mold, and a rotary plate, neck support fixing plate and neck support member for conveying the moldings through the receiving and removing unit, heat treatment section and final molding section.

摘要:
In an injection stretch blow molding method, at least one injection molded preform is transferred from a preform molding section to a blow molding section by way of a transfer section and the at least one preform is blow molded into at least one container in the blow molding section. In the preform molding section the at least one preform is injection molded in an upright state with an open neck section thereof facing upward. In the transfer section, the at least one upright preform is turned upside-down and transferred to the blow molding section in an inverted state. Then, the blow molding section blow molds at least one container from the at least one inverted preform.
摘要:
An injection stretch blow molding apparatus and method wherein while the preforms are amply cooled the injection molding cycle time is shortened and furthermore a small number of blow cavities are used. In an injection molding section, N (N.gtoreq.2) preforms are injection molded in an upright state and then released from the injection cavity mold. While the preforms are cooled by the injection core mold, they are carried to a preform ejecting section. After the preforms cool to a temperature at which they can be ejected, the preforms are ejected from the injection core mold. In a transfer station, an array pitch of the simultaneously molded preforms are changed to a blow molding pitch, and then the preforms are transferred to a blow molding station in an inverted state. In the blow molding station, each preform is carried by a carrier member through a heating section into a blow molding section. In the blow molding section, n bottles are simultaneously blow molded from n preforms.

摘要:
An injection stretch blow molding apparatus has a preform molding section for molding preforms and a blow molding section for blow molding containers from the preforms retaining heat from when the preforms were injection molded. At a location in a path along which the preforms are carried from the preform molding section to the blow molding section there is a discharge guide section for guiding preforms which are not to be carried to the blow molding section off the carrying path. A method wherein preforms are injection molded in preform molding section and these preforms are carried to a blow molding section and containers are blow molded from the preforms retaining heat from when the preforms were injection molded, includes the steps of switching to either a container molding operating mode using the above steps or a preform molding operation mode wherein part way along the preform carrying path leading to the blow molding section, the preforms being molded in the preform molding section are discharged from the carrying path.
