Device for processing preforms—fast changer

A tempering device, comprising:

• a holder device configured to hold at least one preform, the at least one preform having an inner wall part and an outer wall part;
• and
• a mould carrier device adapted to releasably hold a contact device,
• the mould carrier device having a holding zone adapted to hold the contact device,
• connections to the carrier adapted to supply a tempering medium to the carrier,
• a thermosensor adapted to determine a temperature of the tempering medium, the carrier device and/or the preform,
• the contact device being at least partially radially surrounded by the carrier device and positioned radially outward from the preform, said contact device including a contact contour extending in one of a straight line along a longitudinal direction of the at least one preform, or extending in a curve and is curved in sections along the longitudinal direction of the at least one preform and touching a first wall part of the at least one preform,
• the holder device being separate from the contact device at least in a closed state and being adapted to hold the first wall part of said at least one preform in at least partial contacting arrangement with the contact contour of said contact device while a second wall part of said preform is longitudinally spaced from the first wall part, wherein the first wall part and the second wall part correspond to a portion of the outer wall facing the contact contour,
• the contact contour being adapted to prespecify a temperature of the first wall part, wherein the temperature of the first wall part at least temporarily differs from a temperature of the second wall part that is always spaced from the contact contour,
• wherein the carrier device comprises a plurality of outer holding zones, each outer holding zone being adapted for holding at least temporarily and at least partially radially surrounding a contact device for tempering the wall part, and
• further comprising coupling connections adapted for coupling the outer holding zones and the contact devices wherein the coupling connections comprise a sliding section within the outer holding zone, wherein the sliding section is an indented portion within the outer holding zone, a plurality of spring loaded bolts spanning into the sliding section, a clamping element located at an end of each bolt within the sliding section adapted to pretension a positioning device, and wherein the sliding section and the clamping elements are adapted to guide the positioning device of the contact device vertically from a lower opening of the sliding section located on a lower end of the carrier device to an upper end of the sliding section located on an upper end of the carrier device.
