An apparatus for shaping plastics material pre-forms into plastics material containers has a conveying device which conveys the plastics material pre-forms along a pre-set conveying path. The conveying device has a movable station carrier arranged at least indirectly on a stationary base carrier and on which a plurality of shaping stations are arranged. The shaping stations have blow molding devices which form cavities inside which the plastics material preforms are shaped to form plastics material containers. The blow molding devices are arranged on blow mold carriers. The apparatus has a changing device suitable for removing at least the blow molding devices from the blow mold carriers and/or arranging blow molding devices on the blow mold carriers. A changing device has a gripping device for gripping the blow molding device, wherein this gripping device is movable in at least two different directions and is pivotable about at least three different axes.
An apparatus for the shaping of plastics material pre-forms into plastics material containers with a conveying device which conveys the plastics material pre-forms along a pre-set conveying path, wherein the conveying device has a movable station carrier which is arranged at least indirectly on a stationary base carrier and on which a plurality of shaping stations are arranged, wherein these shaping stations have in each case blow moulding devices which form cavities in each case inside which the plastics material preforms are capable of being shaped to form the plastics material containers and these blow moulding devices are arranged in each case on blow mould carriers, wherein the apparatus has a changing device for removing at least the blow moulding devices from the blow mould carriers thereof and/or arranging blow moulding devices on the blow mould carriers, wherein this changing device has a gripping device for gripping the blow moulding device, wherein this gripping device is movable in at least two different directions and is pivotable about at least three different pivot axes, wherein the gripping device is arranged on an arm pivotable about at least one pre-set pivot axis, and wherein the base carrier is a machine frame and the changing device is at least indirectly disposed on the base carrier.
A method of operating a shaping device for the shaping of plastics material pre-forms into plastics material containers, wherein the plastics material pre-forms are conveyed in a working operation of the apparatus along a pre-set conveying path by a plurality of shaping stations and are expanded to form the plastics material containers by being acted upon with a flowable medium, wherein in order to expand the plastics material pre-forms use is made of blow moulding devices in the interior of which the plastics material pre-forms are expanded to form the plastics material containers, wherein at least one of the blow moulding devices is removed in a changing operation from the apparatus and/or one of the blow moulding devices is arranged on a blow mould carrier of the apparatus, wherein in order to change the blow moulding devices use is made of a changing device which has a gripping device for gripping the blow moulding device, wherein this gripping device is movable in at least two different directions and is pivotable about at least three pivot axes, wherein the gripping device is arranged on an arm pivotable about at least one pre-set pivot axis, and wherein a stationary base carrier on which a plurality of shaping stations is arranged is provided, wherein the base carrier is a machine frame and the changing device is at least indirectly disposed on the base carrier.
An apparatus for the shaping of plastics material pre-forms into plastics material containers with a conveying device which conveys the plastics material pre-forms along a pre-set conveying path, wherein the conveying device has a movable station carrier which is arranged at least indirectly on a stationary base carrier and on which a plurality of shaping stations are arranged, wherein these shaping stations have in each case blow moulding devices which form cavities in each case inside which the plastics material preforms are capable of being shaped to form the plastics material containers and these blow moulding devices are arranged in each case on blow mould carriers, wherein the apparatus has a changing device for removing at least the blow moulding devices from the blow mould carriers thereof and/or arranging blow moulding devices on the blow mould carriers, wherein this changing device has a gripping device for gripping the blow moulding device, wherein this gripping device is movable in at least two different directions and is pivotable about at least three different pivot axes, wherein gripping device has active gripping elements which produce a positive and force-fit engagement with the blow mould device, wherein the gripping device produces a positively engaged connection between two side parts of the blow mould device and furthermore a force-fit connection between the side parts and a base mould of the blow mould device.
