- Fig. 7 shows a schematic plan view of a system for producing tubular - -
- Fig. 8 is a schematic perspective view of the system of Fig. 7.
- Fig. 9 is a schematic perspective partial view of the manufacturing area of the system of Fig. 7.
- Fig. 10 is a schematic front view of the system of Fig. 7.
- the system of the seventh embodiment comprises a manufacturing area A with fully automated manufacturing stations and a mold conveyor 20 and a curing area B with a transport orientation 30.
- the production stations comprise first and second decoating stations 1 and 2, a mold core cleaning station 3, an outer mold cleaning station 4 and a forming equipment station 5.
- the system of the fourth embodiment has first and second mold filling stations 6a and 6b.
- the system of the fourth embodiment has additional optional manufacturing stations 7a to 7e. These are a mold core coating station 7a, a mounting station 7b and a loading station 7c in the region of the first mold conveying section 20a between the mold core cleaning station 3 and the forming equipment station 5.
- the insertion station 7c is set up, for example, to optionally attach reinforcing baskets to forming cores arranged at the insertion station 7c, and the insertion station 7c is supplied with reinforcement baskets fully automatically via a reinforcement cage magazine 9a and a reinforcement cage handling device 9b as required.
- outer mold coating station 7d and a second assembling station 7e in the region of the second mold conveying section 20b between the outer mold cleaning station 4 and the forming equipment station 5.
- a product handling device 10 is provided, which is adapted to rotate a finished concrete product PR arranged at the product discharge position P2 in a horizontal orientation and transfer it to a product conveyor 11.
- concrete products PR stored and transported, and then removed from the system.
- concrete products PR can be post-processed (eg by milling).
- a test station can also be provided for automatic testing and quality assurance of the concrete products.
- a palletizing device may also be provided.
- the curing area B comprises a plurality of respective subregions, here by way of example the subareas B1 to Bll.
- the plurality of molds stored in the curing area B analogous to the first embodiment, a plurality of groups of molds, wherein molds of a group have a same mold size and molds of different groups have different mold sizes, and wherein the stored in the curing area B molds after Groups are arranged and molds of a group in a contiguous common sub-area of the curing area B are arranged.
- 11 groups of casting molds G1 to G11 with eleven different mold sizes namely a first group of molds G1 of a first mold size, which are arranged grouped in the first subregion B1, a second group of molds G2 of a second mold size, which are stored grouped in the second subregion B2, a third group of molds G3 of a third mold size, which are arranged grouped in the third subregion B3, and a fourth group of molds G4 of a fourth shape size, which are stored grouped in the fourth sub-area B4, etc.
- casting molds of several (here by way of example three) different dimensions can thus be in circulation of the production system at the same time, so that the production of tubular concrete products of very different sizes and, if necessary, molds in the same circulation cycle with advantageous avoidance of set-up times or downtimes.
- FIG. 11 shows a schematic sectional view of the production area of the system from FIG. 7 along sectional axis A - A.
- the first mold conveying section 20a is adapted to form a mold core F in a first lower level from the second decoating station 2 behind the first decoating station 1 in FIG 11 to convey the forming equipment station 5, and the second forming section 20b is configured to have an outer mold AF in a second upper plane from the first decoating station 1 to the forming equipment station 5.
- the second level is located above the first level.
- a cleaning operation on the outer mold cleaning station 4, a coating operation on the coating station 7d, and a mounting operation on the mounting station 7e can thus be advantageously carried out from below on the outer molds AF.
- the molds G and mold cores F are always conveyed in the first plane, and the mold conveyor 20 is adapted to convey a filled mold G in the first plane from the mold input position PI to the first mold removal station 1, a mold core F having a cured tubular concrete product in the first plane from the first decoiling station 1 to the second decoiling station 2, to convey a cured concrete concrete product PR removed at the second decoating station 2 in the first plane to the product discharge position P2, a mold G composed at the forming equipment station 5 in the first one To convey level to the filling station 6, and to convey a filled at the filling station 6 with concrete mold G in the first plane to the mold discharge position P3.
- the first de-scaling station 1 is hereby set up, for example, to pull an outer mold AFI upwards into the second plane from a concrete product PR1 inserted on a mold core, if necessary by opening a multipart outer mold, and the mold-arming station 5 is set up to form an outer mold for assembling the Cast mold GF from the second level in the first level down over a arranged on the Formrüststation 5 mold core.
- the outer molds AF are always conveyed in the second upper plane by means of the mold conveying section 20b (see also Fig. 9).
- the mold conveyor 20 be designed as a chain conveyor, for example, but the present invention is not limited to chain conveyors.
- the transport device 30 may be designed as a robot crane.
- the tubular concrete products produced by a system of the present invention can be made in a variety of designs and shapes (optionally, depending on the optional manufacturing stations and molds provided, even without additional set-up times in a single circulating system).
- This includes concrete pipes of all shapes, profiles and sizes, and pipes with and without reinforcements or inner pipes, e.g. made of plastic.
- the present invention makes it possible to provide a system and method in which tubular concrete products can be automated and efficiently produced by casting at lower cost and with high quality and reliability, and more particularly to provide a system and method in which tubular concrete products of different dimensions can be automated and efficiently produced by casting at low cycle times, with no need for set-up times and, in particular, low downtimes.
