    • The invention relates to a heating device (H) for the thermal conditioning of preforms (1) made of a thermoplastic material at a temperature profile that is suitable for a blow molding and a blow molding machine (B) having a heating device (H) of this type. The heating device (H) has multiple heating units (30, 30′) arranged behind one another along a heating section (24) and transport means (33) for transporting the preforms (1) on a transport path (55) along the heating section (24) and along the heating units (30, 30′). The transport means (33) are connected in a chain-like manner to form a closed continuous transport chain (50) and have a rotary drive body (52) that cooperates with a first engaging device (51) that is driven and arranged such that it circulates at a distance to the transport chain (50) in order to introduce a rotational movement thereof about a longitudinal axis of the transport means (33) via engagement in the rotary drive body (52). The heating device (H) has a first heating section with first heating units (30) for the uniform heating of the preforms (1) in their peripheral direction and a second heating section with second heating units (30′) for the non-uniform heating of the preforms (1) in their peripheral direction (preferential heating). The first engaging device (51) is arranged in such a way that it is engaged with the rotary drive body (52) in the region of the first heating section and is not engaged with the rotary drive body (52) in the region of the second section. The heating device (H) has a second engaging device (45, 45′, 45″) that can be driven and is arranged such that it circulates at a distance to the transport chain (50), said second engaging device being arranged in such a way that it is engaged with the rotary drive body (52) in the region of the second heating section and also has the translation speed of the transport chain (50). Furthermore, the invention relates to a method for the thermal conditioning of preforms.

    • A method for controlling a blow-molding machine for producing a thermoplastic container, wherein a blowing gas for blow-molding the container is introduced into a thermally conditioned preform, while the preform is held in a blow mold of the blow-molding machine. The blowing gas is introduced during a preblowing phase into the preform so that the temperature-conditioned material of the preform approaches the walls of the blow mold. The blowing gas is introduced during a following finish-blowing phase into the preform so that the temperature-conditioned material of the preform is pressed into the contours of the blow mold walls. The volumetric flow rate of the blowing gas is determined at least during the preblowing phase by an adjustable flow-control valve that can be controlled by a control unit that generates a control signal for adjusting the flow-control valve. The flow-control valve is adjusted as a function of the control signal.
    • 一种用于控制用于制造热塑性容器的吹塑机的方法,其中用于吹塑成型容器的吹塑气体被引入到热调节预制件中,同时将预成型件保持在吹塑机的吹塑模具中。 吹塑气体在预吹制阶段被引入到预成型件中,使得预成型件的温度调节材料接近吹塑模具的壁。 吹制气体在随后的精加工阶段被引入到预成型件中,使得预成型件的温度调节材料被压入吹塑模具壁的轮廓中。 吹送气体的体积流量至少在预吹制阶段由可调节的流量控制阀确定,该可调节流量控制阀可以由产生用于调节流量控制阀的控制信号的控制单元控制。 根据控制信号调节流量控制阀。

    • The invention relates to a conveyor system for conveying preforms in a device for blow-forming finished containers, wherein the conveyor system comprises a conveyor chain, the chain links of which comprise a carrying element and a conveyor element, the conveyor system being characterized in that the conveyor element comprises a support structure and the carrying element comprises a mounting structure and at least some sections of the support structure and the mounting structure are designed and arranged to complement one another. Both the support structure of the conveyor element and the mounting structure of the carrying element comprise at least one connecting element, at least some sections of each connecting element being configured and arranged to complement one another, and the conveyor system is further configured to handoff the preforms to carrying elements for conveying said preforms through a heating section and to remove the preforms from the carrying elements after said preforms have been conveyed through the heating section. In addition, the invention also relates to a device for blow-forming finished containers from preforms, in particular from preforms made of a thermoplastic material, the device comprising at least one heating system for thermally conditioning the preforms along a transport path and at least one forming device for forming thermally conditioned preforms into the finished container, characterized in that the device comprises at least one conveyor system for conveying preforms according to the invention, the conveyor system being disposed in particular in the area of the heating device. Lastly, the invention also relates to the use of such a conveyor system and a method for the replacement of at least one carrying element.
