Provided is a resin container manufacturing method including: an injection molding process of injection molding a plurality of preforms along a predetermined arrangement direction; a temperature adjustment process of adjusting a temperature of the preform; and a blow molding process of molding a resin container from the preform. After the injection molding process, the preform and the container are conveyed along a conveying direction intersecting the arrangement direction over the temperature adjustment process and the blow molding process. The temperature adjustment process includes a first temperature adjustment process of adjusting the temperature of the preform, a second temperature adjustment process of adjusting the temperature of the preform under a condition different from that of the first temperature adjustment process, and a fine adjustment process of finely adjusting the temperature of the preform.

Method for producing resin container and apparatus for producing resin container

This method for manufacturing a resin container includes injection molding a plurality of preforms in an arrangement direction, a adjusting the temperature of the preforms, and molding containers from the preforms. The manufacturing method includes, between the injection molding and the temperature adjusting, changing the orientation of the preforms aligned in the arrangement direction to an orientation aligned in a conveying direction.

Method for manufacturing resin container, and device for manufacturing resin container

An apparatus for molding a handle-equipped container is provided. The apparatus has a gripping mechanism sectionwhich comprises a first gripping memberhaving a pair of first chuck membersfor grasping a preform, and a second gripping memberhaving a pair of second chuck membersfor grasping a container handlein association with the action of the first gripping member. The apparatus can simultaneously grasp a plurality of the preformsand a plurality of the container handlesand reliably transport them to a blow molding section.

Apparatus for molding handle-equipped container, and mold and mold unit for use in same

A blow molding device and a blow molding method are disclosed that can blow-mold a container with a handle without requiring a handle inserter that inserts a handle into a blow molding section. A blow molding method for blow-molding a container with a handle includes heating a preform () that is held by a heating transfer jig (), transferring the preform from the heating transfer jig to a blow transfer jig (), and transferring the blow transfer jig in a state in which a handle () is held by the blow transfer jig to be adjacent to the preform in a transfer direction.

Blow-molding method for container with handle and blow-molding equipment

A container with a handle, in which a handle is engaged with a portion of the container, is manufactured by arranging the handle in a handle arrangement part, inserting a bottomed tubular preform into a cavity of a mold and performing blow molding. The mold includes an inner wall surface that forms an external shape of the container and a pressurizing member that forms a handle engaging part engaging with the handle to a portion of the container, and the pressurizing member is capable of moving between a first position which is a position at an outer side of the inner wall surface and a second position at which a portion of the inner wall surface is formed.

A preform heating apparatus has cover membersprovided to close upper parts of two transport lines arranged in parallel, heating unitseach having heatersfor heating preforms, and a first supply section for supplying cooling air into the cover members. The heating unitsare each provided within each cover memberon a side between the transport lines. The first supply section introduces cooling air from air delivery spacesprovided between the transport lines into the cover membersthrough gaps between the heatersto supply the cooling air toward the preforms

Preform heating apparatus

A transport apparatus () for transporting a preform () for blow molding comprises: a transport device that transports the preform while allowing the preform to rotate on its axis in a horizontal direction; and an engaging device () that engages the preform being transported while being allowed to rotate on its axis, and setting the orientation of the preform to a predetermined orientation. The engaging device engages a convexity or a concavity provided in the outer periphery of the preform.

Transport apparatus

In an embodiment, an injection stretch blow molding device includes an injection molding section that produces N (N is an integer equal to or larger 2) preforms by injection molding, a cooling section that subjects the N preforms transferred from the injection molding section to forced cooling, a heating section that continuously transfers and heats the N cooled preforms, and a blow molding section that subjects the N heated preforms to stretch blow molding in n (n is an integer equal to or larger than 2) operations, the blow molding section simultaneously stretch blow molding M (M=N/n, M is a natural number) preforms among the N preforms into M containers.

Injection stretch blow molding device and molded part heating device

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.

Injection stretch blow molding device with transfer station and pitch changing for blow molding

An injection stretch blow molding apparatus has an injection molding station and a blow molding station, with a transfer station positioned therebetween. The injection molding station has an injection molding section which molds preforms and a removal section which removes the preforms from an injection core mold. The blow molding station carries out circulating transfer of carrying members which support the preforms, and in the blow molding section the preforms are blow molded into containers. The transfer station has a receiving mechanism which receives preforms removed from the injection core mold in the injection molding station in the upright state, an inverting receiving mechanism which inverts the preforms and passes them in the inverted state to carrying members, and between the receiving mechanism and the inverting receiving mechanism, a movement mechanism transferring the preforms from the receiving mechanism to the inverting receiving mechanism.
