摘要:
A device for treating at least one container, preferably for filling at least one container with a fill product and/or for reshaping a container, comprising an isolator chamber containing a defined atmosphere, in which the treatment of the container is carried out, and at least one container channel for conveying the container into the isolator chamber or for conveying the container out of the isolator chamber, and a suction device for sucking air out of the container channel and out of the isolator chamber, and a supply air preparation unit for preparing the air to be fed to the isolator chamber, wherein the suction device is connected with the supply air preparation unit in such a manner that at least a portion of the air sucked out of the container channel and/or the isolator chamber is fed to the supply air preparation unit for renewed preparation.

An apparatus for shaping plastic preforms into plastic containers, including a plurality of blow molding stations which each have a cavity in which the plastic preforms can be shaped into plastic containers. The blow molding stations are arranged on a movable carrier and each have a stretching rod which stretches the plastic containers in their longitudinal direction by a movement in a stretching direction. A fluid-actuated drive device is provided for driving the stretching rod in the stretching direction. The apparatus includes a guide cam which is arranged in a stationary manner and by means of which the stretching rod can be moved counter to the stretching direction as a function of a movement of the blow molding station. At least one portion of the guide cam is adjustable and, for example, by virtue of this adjustment a dependency of the movement of the stretching rod on the movement of the blow molding station can be varied.
摘要:
A blow molding machine with air conditioning that while minimizing the introduction rate of outside air maintains constant temperature in a plant building and the interior of a blow molding machine and production of a bottle as a final configuration with stability in its measurement value. The machine is constructed so that air for biaxially stretching blow molding together with hot air of heating zone and internal air of a plant building is suctioned by suction chamber, filtered by primary filter and secondary filter into clean air, brought into heat exchange with primary cooling coil, fed under pressure by air blower and released through low-temperature duct into the interior of the plant building. Further, a housing on its side face is provided with vent to allow reflux of the clean air released into the interior of the plant building and flow into the heating zone and blow zone.

The invention relates to a method and a device for blow-molding containers. Following thermal conditioning inside a blow-mold of a blow-molding machine, a preform (1) is formed into the container (2) by means of blowing pressure. The necessary blow-molding gas (P1, P2) is provided by a supply device. The stored, pneumatic pressure energy inside the blown container is at least partially transformed into another form of energy.
摘要:
A method for the at least two-stage temperature control of preforms (28) made from a thermoplastic material. In this method, the preforms (28) are brought, immediately prior to a blow molding or a stretch blow molding process, to a process-specifically distributed softening temperature (T3) according to a predefineable thermal profile, with said softening temperature (T3) being the temperature required for blow molding or stretch blow molding at least the preform's (28) body section located below the thread section (29) and/or a collar area located therebelow. In addition, the preforms (28) are first preheated to a near uniform temperature, particularly with a largely homogeneous temperature distribution (T2).The invention furthermore includes a heating device (10) for performing the method.

A method of controlling a blow molding machine from a completion of production of one product to a start of production of a next product comprises controlling a temperature of a resin within the blow molding machine, controlling an operation of devices from the completion of production of the one product to the start of production of the next product, controlling a sequent transport of some of the devices in predetermined positions, and controlling a change of the resin in accordance with a supply stop thereof and a data on the next product.
摘要:
A container manufacturing plant (10) includes an air circuit (78) employing a recycling method that includes at least the successive steps of: extracting filtered air from an oven (26), after the air has been used in the latter, for the purpose of cooling at least one part of the preforms; treating the sterilizing agent present in the extracted air resulting from the sterilization of the preforms; and recycling the extracted and treated air to the industrial area (16) where the plant (10) is installed. An air recycling method is also described.
摘要:
A process for manufacturing a plastic hollow body by molding two sheets of molten plastic in a mold including two cavities, the process including: a) two molten plastic sheets are manufactured by extrusion of at least one stream of molten plastic and transverse cutting thereof; b) these sheets are introduced between the mold cavities; c) the mold is closed and the hollow body is manufactured by conforming the two sheets to the mold cavities; d) the hollow body thus obtained is removed from the mold; e) all of operations a) to d) are repeated to manufacture another hollow body from two new sheets; and before, during, or after the transverse cutting operation, the lower portion of the two new sheets is cooled using a specific device that makes possible a local cooling of the sheets in the lower portion.
摘要:
Hollow part manufacturing machine includes at least one mould in which hollow parts can be manufactured by application of a pressurised medium, a valve unit, having at least two valves, wherein an inlet of a second valve is connected to a second pressure accumulator, which is pressurised under a second pressure, and an outlet of the second valve is connected to a blow nozzle via a channel. The inlet of a first valve is connected to a first pressure accumulator that is under a first pressure and the outlet of the first valve is also connected to the blow nozzle via a channel. During at least a part of the moulding process, the blow nozzle seals the material to be moulded, and/or the mould, relative to the environment.
