Definitions

  • the invention relates to a machine for shaping roofing means out of concrete by extrusion in which each roofing means at one end is provided with an integral flange portion that is substantially perpendicular to the main direction of the roofing means and in which metal under-moulds are used each comprising a main portion shaping the lower side of the roofing means, a transverse portion at one end of said main portion shaping one side of said flange portion and a flange at the lower end of said transverse portion shaping the lower part of said flange portion.
  • a machine used therefore comprises in general a horizontally extending conveyor track, in which under-moulds, so-called pallets, linked one behind the other are moved along with the aid of conveyor chains or such.
  • a shaping box is mounted with the reservoir for concrete, a mixing roller, a shaping roller and a doctor plate.
  • This doctor plate together with the shaping roller takes care of the shaping of the upper face of the tiles (US-A-3122812).
  • On the upperside of the tiles no projections in cross direction are present for this is not possible in an extrusion method.
  • the lower side of the tiles indeed have projections in cross-direction, such as suspension bosses. These bosses are molded by appropriate recesses in the under-moulds. These projections only have a restricted height and do not give difficulties.
  • roofing means in the shape of the gable tiles these being tiles with a flange at one of its longitudinal sides, thus extending in the extrusion direction, can be made in a satisfactory way it is not possible to shape with the aid of such a device roofing means having a flange transverse to the extrusion direction.
  • roofing means having a flange transverse to the extrusion direction.
  • roofing means are chaperon tiles, under-tiles, first ridge tiles and end ridge tiles.
  • roofing means with a flange along a longitudinal side and a flange along the upper or lower side in fact a combination of gable tiles and chaperon tiles or under-tiles.
  • Chaperon tiles that is to say tiles with a flange along the upper side, are used to finish pent-roofs that are applied more and more.
  • Under-tiles that is to say tiles with a flange along the lower side, are used to seal off the lower edge of a roof, among others against entering by birds and against looking in to the lower tile lath.
  • roofing means provided with a transverse flange cannot be shaped by the normal continuously working machine because of the fact that the filling and the compacting of the mortar into the moulding cavity, delimiting the transverse flange, is not satisfactory.
  • the main reason is that the moving pallet cannot be supported in a sufficient exact manner with regard to the transverse wall, that delimits the other side of the flange portion and cannot be integral with the pallet. If this would be the case then the shaped roofing means cannot be released from the pallet.
  • Another reason is that no sufficient time is available to transmit sufficient concrete in the shaping cavity of the flange portion and to compact it.
  • the invention aims to provide a machine with the aid of which roofing means with flange portions can be shaped mechanically. By this the disadvantages of the manual shaping method such as filling and compacting the shaping cavity for the flange portion are avoided.
  • the machine according to the invention is characterized in that the machine comprises a horizontal rectangular stationary frame and in it in series a number of stations for shaping one roofing means at a time, each station comprises side walls and transverse walls in which an under-mould can be fitted and comprises supports for supporting the undermould in vertical direction in such a manner that the shaping cavity for the flange portion is defined by one side of a transverse wall of the station in said frame, one side of the transverse portion of the undermould and the upperside of the flange of the undermould, said machine further comprises a movable frame, that can be displaced along the stationary frame and that is provided with means to fill all stations in one step with concrete to compact and to shape its upperside.
  • the machine according to the application comprises a stationary frame and a movable frame.
  • the stationary frame is rectangular, extends in horizontal direction and comprises a number of substantially horizontally extending parallel longitudinal rails, supported by legs.
  • the legs are indicated by 1 and a number of longitudinal rails are indicated by 2 and 3 resp.
  • each under-mould comprises an in general horizontally extending profiled main part 4a, a transverse part 4b destined to shape one side of the flange portion of the roofing means and a flange 4c destined to shape the lower edge of the flange portion.
  • Each under-mould 4 fits between two vertical transverse walls 5 and two vertical side walls 6, 6 of the stationary frame. It will be clear that the upper limit of each transverse wall 5 has to be adapted to the curvature of the roofing means to be shaped.
  • each shaping station is formed by two U-beams 7 extending along the length of the stationary frame.
  • supports 8 are mounted on which the longitudinal axes of the under-mould 4 are supported when the under-mould is positioned on its place in the stationary frame.
  • each under-mould is fittingly enclosed by the transverse walls 5 and the side walls 6 and is supported in vertical direction by the supports 8. It will be clear that still more supports can be provided, for instance on the transverse walls 5, so that each under-mould also is supported at both or at one head end.
  • each station pneumatic lifting means 9 are present which are able to move the under- mould 4 vertically upwards from its place in a stationary frame (see fig. 1).
  • the movable frame is indicated by 20 and is supported at one side with the aid of rollers 21 by the square longitudinal beam 2 of the stationary frame and at the other side by rollers 22 resting on the U-beam 3 of the stationary frame.
  • a rack 23 is mounted along which a pinion can roll. This pinion is driven with the aid of motor 25 that moves together with the movable frame 20.
  • the movable frame 20 comprises essentially a shaping box 26 in which from a hopper concrete can be casted. During the filling of the shaping box 26 the movable frame 20 is at one end of the stationary frame. It will be clear therefore that the stationary frame has to be provided with a part without shaping stations. At the other end also such a part is present above which the frame 20 is present in case the whole extrudate is extruded.
  • a second motor 27 drives through a chain 27a or such the shaping roller 28. From this shaping roller 28 through a second chain 29 or such a shaft 30 is driven that is provided with pins or such that are meant to keep the concrete in movement and to press it below the shaping roller 28.
  • a second chain 29 or such a shaft 30 is driven that is provided with pins or such that are meant to keep the concrete in movement and to press it below the shaping roller 28.
  • Such a construction is known per se for a machine for shaping ordinary tiles, i.e. tiles with flange parts.
  • the shaping box 26 is limited at its side edges by side walls moving slidingly over longitudinal strips 6, while the front side is delimited by a cover plate indicated by 31 and at the back a doctor plate 32 is present, of which the lower edge determines the final upper shape of the roofing means to be shaped.
  • This plate 32 together with the upperside of the row of under-moulds 4 forms the extrusion mouth for the extrudate.
  • the frame 20 is present above the part without shaping stations at one end of the stationary frame.
  • the filling station not shown, is at the right hand side of the drawing.
  • the drive motor 27 for the shaping roller 28 and the mixing shaft 30 are put into action.
  • the concrete comes at the right hand side in figure 1 out of the shaping box 26 through the extrusion mouth.
  • the concrete is pressed by the shaping roller 28 into the under-moulds 4 and also in the cavity of each flange portion.
  • the compacting of the concrete also is caused by the shaping roller 28 while the lower edge of the doctor plate 32 wipes the upper side of the extrudate.
  • the frame 20 arrives above the left blind portion of the stationary frame and is stopped.
  • the shaped extrudate has to be divided on the spot of the transverse walls 5.
  • one or more vertical moving cutting devices 33 see fig. 2, are used.
  • the or each cutting device 3 comprises two parallel cutting knifes 34 so that between the cutting knifes a space is present.
  • the cutting of the extrudate preferably takes place after the shaping of the whole extrudate that is to say when the frame 20 is above the left hand blind portion.
  • each under-mould 4 is moved upwardly and can be taken off so that the roofing means shaped thereon can be dried in a drying device after which the roofing means can be taken from the under-mould.
  • the capacity of the device can be increased by shaping a number of series roofing means next to each other in one step.
