Abstract
Provided is an apparatus for molding plastic preforms into plastic containers, with at least one blow molding arrangement, which includes at least a first mold carrier, a second mold carrier and a blow-molding device having at least two blow mold side parts and a base part, wherein the blow molding device can be releasably arranged on the mold carriers via a locking mechanism and forms a cavity inside which the plastic preforms can be molded into the plastic containers, wherein during the molding process, the mold carriers can be latched together by a latching device, and the apparatus includes a changeover robot which is suitable and intended for extracting the blow-molding device in an assembled state from the mold carriers.

An apparatus for molding plastic preforms into plastic containers, with at least one blow-molding arrangement, which comprises at least a first mold carrier, a second mold carrier and a blow-molding device having at least two blow mold side parts and a base part, wherein the blow-molding device can be releasably arranged on the mold carriers via a locking mechanism and forms a cavity inside which the plastic preforms can be molded into the plastic containers,
- wherein during the molding process, the mold carriers can be latched together by a latching device, and the apparatus comprises a changeover robot which is suitable and intended for extracting the blow-molding device, in an at least partially assembled state, from the mold carriers, wherein in a changeover mode, the mold carriers are operated to be opened or closed exclusively by the changeover robot, and the locking mechanism of the blow-molding device on the mold carriers can be actuated to be released or attached exclusively by the changeover robot, and the latching device can be operated by the changeover robot in a changeover mode.
A method for operating a molding device for molding plastic preforms into plastic containers, with at least one blow-molding arrangement, which comprises at least a first mold carrier, a second mold carrier and a blow-molding device having at least two blow mold side parts and a base part, wherein the blow-molding device can be releasably arranged on the mold carriers via a locking mechanism and forms a cavity inside which the plastic preforms can be molded into the plastic containers by bombardment with a fluid medium, wherein during the molding process, the mold carriers can be latched together by a latching device, and a changeover robot is provided for extracting the blow-molding device from the mold carriers, and extracts the blow-molding device in an assembled state, comprising the steps of:
- in a changeover mode, the mold carriers are opened exclusively by the changeover robot, and the locking mechanism of the blow-molding device on the mold carriers is released exclusively by the changeover robot.
A method for operating a molding device for molding plastic preforms into plastic containers, comprising:
- providing at least one blow-molding arrangement having a first mold carrier, a second mold carrier, and a blow-molding device having at least two blow mold side parts and a base part, wherein the blow-molding device can be releasably arranged on the mold carriers via a locking mechanism and forms a cavity inside which the plastic preforms can be molded into the plastic containers by bombardment with a fluid medium,
- providing a changeover robot for extracting the blow-molding device from the mold carriers,
- latching the mold carriers together by a latching device,
- molding the plastic preforms into plastic containers, and
- performing a changeover, the changeover including at least one of:
- opening the mold carriers exclusively by the changeover robot,
- actuating the locking mechanism exclusively by the changeover robot, and
- operating the latching device exclusively by the changeover robot.
