Definitions

  • the invention relates to a baking device for manufacturing, in particular, high-walled moulded elements from a bakeable moulding substance, comprising
  • a rotary drive for the baking mould support - a plurality of baking mould units held on the baking mould support and distributed in the circumferential direction in relation to the axis of rotation, each with two mould halves, which are superimposed in the axial direction and can be separated from one another, the baking mould units rotating between a baking region and an operating region when the baking mould support is rotated, and
  • Mechanisms for opening and closing the baking mould units in generic baking devices are known, for example, from DE 94 17 702 U and DE 196 17 804 Cl .
  • an upper mould half of each baking mould unit runs, upon entry into the operating region, onto a fixedly arranged control track arrangement extending in the circumferential direction, which extends in curved fashion according to the desired opening and closing profile.
  • Upwardly inclined sections of the control track arrangement result in a lifting of the upper mould halves from the lower [mould halves, whilst the] downwardly inclined sections results in a lowering [of said upper mould halves] .
  • the drive which is used for the rotation of the baking mould units must additionally supply the force which is required in order to drive the upper mould halves up the upwardly inclined control track sections against the force of gravity.
  • this can mean considerable additional loading of the rotary drive, particularly taking into account that the mould halves need to be sufficiently separated in order to provide adequate space for the removal of the fully baked moulded elements and the introduction of fresh moulding substance into the baking mould units.
  • the opening and closing means comprises a lifting arrangement, which can be actuated separately to the rotary drive, for the relative adjustment of the mould halves of the baking mould units.
  • the rotary drive is relieved of lifting tasks, which in comparison with the known solutions allows for a design of the rotary drive with reduced capacity. Instead, the opening and closing of the baking mould units is undertaken by the lifting arrangement.
  • the rotary drive and lifting arrangement can therefore be individually adapted to their respective capacity requirements.
  • the lifting arrangement is preferably constructed as a linear lifting arrangement, which allows for a linear adjustment of the two mould halves of each baking mould unit relative to one another, whilst maintaining their reciprocal spatial orientation.
  • a perfectly linear separation of the axially superimposed mould halves can be attained in that one of the mould halves of each baking mould unit is fitted to the baking mould support so that it is axially non-displaceable and the baking mould support supports a guide column arrangement, on which the respective other mould half is guided in an axially displaceable but non-rotatable manner.
  • the lifting arrangement at least in part as a hydraulic lifting arrangement.
  • this does not, in principle, rule out falling back on different lifting arrangements, for example electromotor or electromagnetic lifting arrangements.
  • the lifting arrangement which is disposed in stationary fashion in said operating station must grasp the incoming baking mould units in order to then execute the desired lifting procedures.
  • the baking mould units then need to be released again from the lifting arrangement, so that they can continue their journey to the baking region.
  • This engagement and disengagement of the baking mould units with/from the lifting arrangement can be effected in a simple and operationally reliable manner in that the lifting arrangement and each baking mould unit comprise cooperating coupling members, by means of which the lifting arrangement and the respective baking mould unit can be brought into releasable lifting engagement, and the coupling member of one of the components: lifting arrangement and baking mould unit forms a continuous guide in the circumferential direction for the coupling member of the respective, other component. It is then possible to produce and release the lifting engagement of the baking mould units with the lifting arrangement solely by moving the baking mould units in the circumferential direction.
  • the lifting aggregates for opening and closing can be constructed differently. Namely, for the closure of the baking mould units and especially in ⁇ . the end phase of the closing procedure, substantially greater forces are often required than during opening. This is associated with the fact that there is often a very high inner pressure in the baking mould units caused by heat and steam after leaving the baking region, which virtually drives the mould halves apart when the baking mould units are opened.
  • the baking mould units In contrast, it is necessary to work against the freshly introduced moulding substance during the closure of the baking mould units in order to distribute said substance uniformly.
  • the baking mould units usually need to be closed in a very sealing-tight manner, which contributes to the high closing forces which need to be applied.
  • the baking mould units can be held in their open position by a holding arrangement on their journey between the two lifting aggregates.
  • a holding arrangement on their journey between the two lifting aggregates.
  • the holding arrangement comprises at least one stationary holding track extending in the circumferential direction, with which a holding member constructed on each of the baking mould units can be displaceably brought into holding engagement in the circumferential direction.

  • the filling with moulding substance or/and the removal of the moulding elements 14 can be effected manually. In order to relieve the operators of the often strenuous tasks at the baking station 12, these tasks can also be carried out automatically.
