Abstract: The invention relates to a gripper for holding workpieces, in particular preforms or containers, in their neck region, having a gripper base on which two gripper arms are pivotably arranged, which each have gripping ends for partially enclosing the neck region, wherein the gripper arms are held in a base position under spring tension, in which the gripping ends can jointly enclose and hold a neck region and, if they come into contact with an obstacle, can be pivoted out of the base position jointly in one direction, wherein one of the gripper arms as the main arm (13, 13′) is clamped via a spring (20) with the gripper base (11), which pulls the main arm (13, 13′) into contact with the other gripper arm, functioning as a secondary arm (14, 14′), in the base position, and the main and secondary arm (13, 13′; 14, 14′) are each mounted in a joint (18, 19), wherein the joint (19) of the secondary arm (14) is closer to its gripping end (16) than the joint (18) of the main arm (13), and the main and secondary arm press against one another in the closed position at least in two regions (21, 22), one of which is located above the joint (19) of the secondary arm (14) and the other below it on a lever (25) of the secondary arm (14) extending downward from the joint (19).

Abstract: The device is used for the blow-molding of containers. A preform made of thermoplastic material, following a thermal conditioning within a blow-mold, is stretched by a stretching rod and is reshaped by effects of blowing pressure into the form of a container. A specification for the positioning of the stretching rod occurs through the use of a linear drive. Blowing pressure is created through the use of at least one positionable blowing gas supply. The linear drive is at least intermittently mechanically coupled with the positionable blowing gas supply and the stretching rod in such a way that coordinated movement kinetics are carried out. The coupling means and the coupled elements are constructed in such a manner that the axis of motion and the resulting force-effect axis form a common spatial axis.

Abstract: The invention relates to devices and methods for transporting preforms (2) made of a thermoplastic material in the region of a blow-molding (10), having a transport wheel (12) which is mounted in a rotatable manner about a rotational axis and which comprises multiple receiving recess (18) distributed in the circumferential direction over the circumference of the transport wheel for receiving and conveying preforms (20). A hook element (14) is arranged on the transport wheel (12) in the region of each receiving recess (18), said hook element being mounted on the transport wheel (12) in a pivotal manner between an open position and a closed position, and in the closed position, the hook element (14) secures a preform (20) to be transported in the respective receiving recess (18) from falling out of the receiving recess (18).

Abstract: The invention relates to devices and to methods for transporting preforms in the region of a blow-molding machine, in particular a sorting device (10) for transporting preforms (20) composed of a thermoplastic material in the region of a blow-molding machine for the blow-molding of containers, comprising a transportation wheel (12), which has a plurality of accommodating recesses (18) for accommodating and conveying the preforms (20), which accommodating recesses are arranged on the circumference of the transportation wheel in such a way that the accommodating recesses are distributed in the circumferential direction, a guide collar (16), which extends circumferentially around the transportation wheel (12) in some regions in such a way that the guide collar is radially spaced apart from the transportation wheel, wherein the preforms (20) are transported in suspension between the transportation wheel (12) and the guide collar (16) in the region of the sorting device (10), and a selection unit for selectively removing a respective individual preform (20) transported in one of the accommodating recesses (18) of the transportation wheel (12), wherein the selection unit comprises a pivotable ejecting star (14) with a plurality of ejecting arms (31), which ejecting star, when in the idle position, reaches into the peripheral region of the transportation wheel (12) by means of a first ejecting arm (31) immediately adjacent to the guide collar (16) in the transportation direction of the preforms (20), in such a way that the preforms (20) in the accommodating recesses (18) that are transported past the first ejecting arm (31) are secured against unintentionally falling out, wherein the ejecting star (14), in the event of a rotational motion, pushes an individual preform (20), which is marked for removal, out of one of the accommodating recesses (18) of the transportation wheel (12) by means of a second ejecting arm (32) following after the first ejecting arm (31), and wherein, in a recurring manner after the preform (20) marked for removal has been pushed out, the second ejecting arm (31) takes on the securing of the preforms (20) transported past the second ejecting arm against falling out of the accommodating recesses (18).

Abstract: A method and a device for producing blow-molded containers which are sterile at least in some areas. A preform made of a thermoplastic material is first heated in a heating device on a transport path through a blowmolding machine and then supplied with a pressurized fluid in a blow-molding device. The preform is guided along a channel, which conducts a sterilizing gas, at least over one sub-section of the transport path of the preform. The transport path of the preform out of the channel is supplied with the sterilizing gas in order to produce a sterilizing gas corridor in which at least the opening region of the preform is guided. Multiple radiation sources are arranged along the channel and one behind the other in the transport direction. The radiation sources emit a sterilizing radiation onto the preform and/or onto the channel, and/or onto the sterilizing gas corridor.
