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 a stretch rod for the form-and-fill head of a machine for forming and filling of containers produced from preforms. The object of the invention is to devise a stretch rod of this type which can be cleaned and/or disinfected without being disassembled and without any other intervention. According to the invention, the object is achieved by a stretch rod (5) for the form-and-fill head (3) of a machine for forming and filling (molding and filling) of containers produced from preforms (2), which rod comprises a drive unit for axially moving said stretch rod (5). At least the part (6) of the drive unit which is connected to the stretch rod (5) is arranged in a drive chamber (11) which is sealed off from the regions of the form-and-fill head (3) which come into contact with the filling material (the material with which the container is being filled). The inventive stretch rod is characterized in that the sealing action is achieved by a seal (12) which surrounds the stretch rod (5).

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).
