Definitions

  • the invention relates to a method and a device for producing undercut depressions in the two side edge webs of a roof tile, the inwardly open depressions serving to receive holding members of a solar cell panel.
  • molds have been used to produce depressions in roof tiles, which are pressed from the inside into the side edge webs of the roof tile molding, which has not yet dried, and form an indentation which is open to the inside.
  • the depressions serve to hold holding members which are attached to the side edges of solar cell panels.
  • the aim of the training is that a correspondingly large solar cell panel can be attached to the roof tiles of a roof for the purpose of electricity production.
  • the indentation of the depressions in the as yet undried clay-containing raw mass of the roof tile molding has several disadvantages. Thus, when the molding tool is pressed in, a deformation of the raw, relatively moist roof tile ormlinings can occur, in particular in the region of the side edge webs.
  • the object of the invention is to develop a method and a device which enable a largely dimensionally accurate design and arrangement of the depressions in the side edge webs of a roof tile.
  • depressions are milled into the dried roof tile molding or into the fired roof tile.
  • the method has the advantage that the drying shrinkage of the roof tile molding, which can be up to 10 percent by volume, took place before the recesses were milled and can no longer have a disadvantageous effect on the dimensionally accurate design and arrangement of the recesses.
  • the remaining shrinkage, which occurs when the roof tile is burning, is up to a maximum of 8 percent by volume so low that the required tolerance can be practically observed. If the depressions are milled into the roof tile that has already been fired, the dimensionally accurate design and arrangement of the depressions is further improved, since in this case the shrinkage of the firing also no longer has an effect.
  • the milling into the dried roof tile molding is generally to be preferred, especially since this method already leads to the required dimensional accuracy.
  • the method according to the invention is also suitable for milling such a depression in roof panels made of other materials, for example of concrete. Insofar as this document refers to roof tiles, this includes roof tiles made of other materials.
  • milling in used here is to be understood in a general sense and also includes methods similar to "cutting in", for example by means of a grinding wheel or the like.
  • a device suitable for carrying out the method has at least two cutters attached to a frame, which can be moved in and out laterally by means of drive elements in the respective side edge web of the dried roof tile molding or the fired roof tile.
  • the milling cutters - or similar cutting tools - differently shaped depressions can be worked into the two side edge webs of the roof tile, whereby these can be adapted to the holding members of the solar cell panels to be used. For example, they can be segment-shaped or groove-shaped.
  • the design of the device can be various. Milling cutters or grinding tools are expediently mounted horizontally displaceably on a crossbar attached to the lower edge of the frame.
  • the frame to which the milling cutters are attached is moved vertically at the beginning of the working process until the associated milling disks are in the cutting plane.
  • the milling cutters are then displaced horizontally, so that the milling disks are laterally pressed in the opposite direction into the two edge webs of the roof tile molding or roof tile, thereby milling or cutting into the depressions.
  • the milling cutters can either be slidably mounted on a crossbar designed as a slide rail.
  • the frame is expediently arranged to be vertically displaceable on guide columns of a frame.
  • the milling cutters can also be arranged on an immovable frame, the roof tile moldings or roof tiles being brought into the milling position by means of a lifting and lowering storage plate or a brick dry frame.
  • the dried roof tile molding or roof tile must be precisely positioned and fixed in a certain position relative to the device.
  • This purpose is served by the dried roof tile molding or roof tiles positioning organs that align towards the frame consist of two slides that can be pressed against the end faces of the roof tile or tile, and of pairs of rollers that are arranged at right angles to it and can be pressed against the side edge webs of the roof tile or tile.
  • a device suitable for carrying out the method is shown as an exemplary embodiment in the drawing; it shows
  • Fig. 1 shows the device in a schematic representation and in view of the end face
  • Fig. 2 shows the subject of Fig. 1 in a schematic plan view.
  • the device shown in FIGS. 1 and 2 is used to mill two undercut depressions 3 into each of the two side edge webs 2 of a dried roof tile molding 1 or an already fired roof tile.
  • the side edge webs can be designed differently, e.g. B. as folds and brims.
  • the roofing tile moldings formed from a plastic-tough clay mass in the extrusion process or pressing process are dried in a known manner. so that they have a relatively high dry strength after removal of water. In this state, they are placed on a storage table 4 or the like and transported under a device for milling two depressions 3 into the two side edge webs 2.
  • the device of the exemplary embodiment consists of a frame 5 which extends over one or more milling stations. At each milling station 5 guide columns 6 are attached to the frame, on which a frame 8 can be displaced vertically from an upper rest position into a lower milling position by means of a lifting drive 7.
  • the frame 8 is provided with two cross members 9, on each of which two milling cutters 10 are pivotable about an axis 12.
  • the four milling cutters 10 are equipped with a milling disk 11 or a grinding disk, which is exchangeable.
  • a milling drive in the form of a drive element 13 is assigned to the milling cutters 10 mounted on a crossmember 9.
  • the milling device is designed such that the frame 8 is lowered at the beginning of the working process until the milling disks 11 are in the cutting plane.
  • the two swivel drives 10 are then actuated, so that the milling disks 11 arranged in pairs are pressed laterally away from one another into the two side edge webs 2 of the roof tile molding 1 and thereby mill or cut the four depressions.
  • the milling depth is limited by stops 20 which are assigned to the cutters 10 and which are preferably designed to be adjustable depending on the wear of the cutting discs 11.
  • the dried roof tile molding 1 must be positioned and fixed in a specific position relative to the device or frame 8.
  • the positioning members provided for this purpose consist of two pushers 14 which can be pressed against the ends of the roof tile molding 1 and two pairs of rollers which are arranged at right angles thereto and can be pressed against the side edge webs 2 of the molding 1 17.
  • the two slides 14 are connected via lever arms 15 to a drive member 16 which pivots the lever arms 15, the pivoting movements being limited in the intended position.
  • the two pairs of rollers 17 also have lever arms 18 and each have a swivel drive 19.
  • the inward pivoting is limited by stops 21 which are attached to the lower crossmember 9.
  • a suction head 22 is arranged in the milling area of each milling cutter 10 and is connected to a suction device via a suction line 23.
  • FIG. 2 indicates that the milling device can be varied in order to machine several dried roof tile moldings 1 or roof tiles at the same time.
  • the frame 5 is assigned several frames 8 etc. with corresponding cutters, drive and positioning elements and suction heads.
  • the exemplary embodiment is designed for incorporating two depressions 3 into each side edge web, it is also possible to assign only one depression 3 or three or more depressions to each side edge web 2 or to design the depression as a continuous groove.

Abstract

La présente invention concerne un procédé de réalisation de renfoncements (3) en contre-dépouille dans les rebords latéraux (2) d'une tuile. Ces renfoncements (3) sont ouverts vers l'intérieur et ils servent à recevoir des organes de fixation d'une plaque de capteur solaire. Pour obtenir une exécution et une disposition améliorées et, dans une large mesure aux cotes des renfoncements dans les rebords latéraux (2), ces renfoncements sont fraisés dans la tuile verte (1) séchée ou dans la tuile déjà sèche. Un dispositif convenant à cet usage possède au moins deux têtes de fraisage (10), fixées à un cadre mobile (8), que l'on peut faire entrer ou sortir latéralement, au moyen d'organes d'entraînement (13), du rebord latéral (2) correspondant de la tuile verte séchée (1) ou de la tuile cuite. Pour aligner la tuile verte (1) ou la tuile par rapport au cadre (8), il y a des organes de positionnement constitués par deux coulisses (14) pouvant être pressées contre les extrémités de la tuile verte (1) ou de la tuile et par des paires de galets (17) disposées perpendiculairement aux coulisses et pouvant être pressées contre les rebords latéraux de la tuile verte (1) ou de la tuile.
