Apparatus for shaping plastics material pre-forms into plastics material containers includes a conveying device which conveys the pre-forms along a pre-set path. The conveying device has a movable station carrier arranged at least indirectly on a stationary base carrier on which are arranged a plurality of shaping stations which have in each case blow moulding devices which have cavities, inside which the pre-forms are shaped. The apparatus has a changing device for removing the blow moulding devices from the blow mould carriers and/or for arranging blow moulding devices on the blow mould carriers. The changing device has a first control device for controlling a removing and/or an arranging movement of the blow moulding devices on the blow mould carriers, and a second control device for controlling a blow moulding procedure, wherein the first control device and the second control device preferably co-operate at least for a time.
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 are arranged a plurality of shaping stations, wherein these shaping stations have in each case blow moulding devices which form cavities in each case, inside which the plastics material pre-forms 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 which is suitable and intended for removing at least the blow moulding devices from the blow mould carriers thereof and/or for arranging blow moulding devices on the blow mould carriers, wherein the changing device has a first control device for controlling a removing movement of the blow moulding devices and/or an arranging movement for arranging the blow moulding device on the blow mould carriers for a changing procedure, and the apparatus has a second control device for controlling a blow moulding procedure, wherein the first control device and the second control device are linked to co-operate at least for a time during the changing procedure, so that when the second control device effects an opening of a blow moulding device during the changing procedure, a replacement of a blow mold by the first control device automatically occurs.
A method of operating a shaping device for the shaping of plastics material pre-forms into plastics material containers, wherein during working operation of the apparatus the plastics material pre-forms are conveyed along a pre-set conveying path using plurality of shaping stations and are expanded by being acted upon with a flowable medium to form the plastics material containers, 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 in a changing operation at least one of the blow moulding devices is removed from the apparatus and/or one of the blow moulding devices is arranged on a blow mould carrier of the apparatus, wherein a changing device is used to change the blow moulding devices, wherein a first control device controls a removal movement of the blow moulding devices and/or an arranging movement for the arrangement of the blow moulding device on the blow mould carriers for a changing procedure, and this first control device co-operates with a second control device for controlling a blow moulding procedure, at least for a time during the changing procedure, so that when the second control device effects an opening of a blow moulding device during the changing procedure, a replacement of a blow mold by the first control device automatically occurs.
