Definitions

  • the invention relates to a method for producing pressed roof tiles from clay, in which the freshly pressed, wet roof tiles are dried and then pass through the oven in a vertical position.
  • the wet, freshly pressed roof tiles are placed horizontally on wooden or metal support pads and these are stacked on several floors and conveyed to tunnel or chamber dryers to dry the pressed roof tiles.
  • the supporting underlays are unstacked and placed on one level, the dry press roof tiles are removed from the supporting underlays and placed vertically close together for firing directly on tunnel kiln cars or placed in cassettes, which in turn are stacked on top of one another in the tunnel kilns. After firing, these must then be unstacked and the roof tiles occasionally laid flat in order to be sorted and packaged according to quality.
  • the invention is therefore based on the object of improving the known method and the known device in such a way that the fully automatic production of press roof tiles is simplified in that certain operations or some of the machines or devices required in the prior art can be dispensed with .
  • This object is essentially achieved in that the freshly pressed roof tiles are placed by the press standing on a conveyor and preferably supported individually in their vertical position on the conveyor, that the roof tiles are picked up in rows by the conveyor and placed in a single layer on a tunnel kiln car be that the end of each row is supported on the furnace car-side contact surfaces, while the individual roof tiles of each row are supported against one another, and that the kiln car with the roof tiles arranged thereon is guided through the dryer and the oven.
  • the freshly pressed roof tiles are placed directly on the tunnel kiln car by the press and the roof tiles pass through both the dryer and the burner standing vertically on the tunnel kiln car without further manipulation.
  • the required placing of the roof tiles on the support base in the known prior art, the stacking of the support base, the unstacking of the support base after drying the roof tile and the renewed deposition of the dried pressed roof tiles in cassettes and the stacking of the cassettes on the tunnel kiln car can thus be omitted in the case of the present invention.
  • spacer lugs are formed on the roof tiles and are separated before the roof tiles are sorted.
  • two spacer tabs could be formed on the side of each roof tile.
  • the spacer lugs are formed on that side of the roof tile which is at the top when the roof tiles are on the conveyor device or the tunnel kiln car; a single, central spacer for each roof tile is sufficient.
  • the spacer lugs ensure that the roof tiles placed in rows on the kiln car can be supported against each other in such a way that a sufficiently large distance is guaranteed between adjacent roof tiles, which ensures optimal, all-round exposure of the press roof tiles with dry air, heating air or cooling air.
  • the wet pressed roof tiles rest on one surface on the supporting base, so they can essentially only be optimally dried from the other side; when firing, the roof tiles are stacked tightly in groups in the conventional manufacturing process, and this makes it difficult to heat or cool the roof tiles.
  • Both in drying and in firing, a much longer drying and / or firing time is therefore required in conventional production methods than in the case of the method according to the invention, and therefore larger dryers and ovens must be used in the prior art.
  • the rows of roof tiles arranged on the conveying device are placed parallel to the conveying direction of the conveying device on the tunnel kiln car and that the tunnel kiln car is guided perpendicular to the conveying direction of the conveying device in the region of the conveying device.
  • the individual rows of roof tiles only have to be moved in a certain plane, namely the vertical plane defined by the direction of transport of the conveyor, without additional turning or pivoting of the rows of roof tiles; this results in a structurally simple construction of the system.
  • the roof tiles are preferably removed again in rows from the kiln car and the rows of roof tiles removed are placed upright on a further conveyor and are preferably individually supported on the conveyor in their vertical position.
  • the devices provided for carrying out these method steps can correspond to the devices provided for transporting the roof tiles from the press to the kiln cars.
  • the roof tiles set down on the conveyor are individually turned over.
  • the inventive device for performing the method is u. a. characterized by a stationary, rotating conveyor device connected downstream of the press, which has at least one support element for each roof tile.
  • the conveyor device can be designed as a conveyor belt which carries support rods which extend essentially perpendicular to the conveyor plane.
  • Such a conveying device is expediently also arranged on the outlet side of the furnace.
  • a tube feed belt 2 feeds an extrusion press 8 with a double-shaft mixer 4 and a screw press 6 with clay material.
  • the clay strand 10 emerging continuously from the screw press 6 is cut by means of the cutter 12 into individual chunks 14 which are automatically inserted into a turret press 16 and pressed by this to form roof tiles 18.
  • the method and the device represent known prior art.
  • a spacer nose 20 is formed on the roof tile moldings 18 pressed in the press 6 and is arranged on that end face of the roof tile mold 18 which is at the top in the further method steps to be described further below. In particular, this can be that end face 22 which is adjacent to the hanging lugs 24 of the roof tile.
  • the spacer nose 20 is connected to the end face 22 of the roof tile 18 via an extension 26, the end of which facing the end face 22 defines a predetermined breaking point with the end face 22.
  • the spacer nose 20 extends substantially perpendicular to the plane of the roof tile 18 and projects beyond the contours of the roof tile 18 in the direction perpendicular to its main plane.
  • the special conveyor belt 30 is designed as a circumferential conveyor belt and has support rods 32 arranged perpendicular to the transport plane, which define individual compartments, into each of which a roof tile 18 is inserted by means of the standing gripper 28.
  • the support rods 32 serve to support the roof tiles 18 against tipping during the cyclical further transport of the roof tiles.
  • a guide arrangement 34 for a stage 36 movable on the conveyor belt 30 is arranged above the conveyor belt 30.
  • the guide arrangement 34 extends parallel to the conveying direction of the conveyor belt 30 and over the conveyor belt 30 to above a tunnel kiln car 38, which is movable below the guide arrangement 34 perpendicular to the latter.
  • the stage 36 which can be moved along the guide arrangement 34, carries a lifting and lowering transfer gripper 40.
  • the transfer gripper 40 By means of the transfer gripper 40, the roof tiles 18 standing upright on the conveyor belt 30 are gripped in rows and, according to the corresponding method of the movable stage 36 and thus the transfer gripper 40, in rows on the tunnel kiln car 38 implemented.
  • the individual rows of roof tiles 42 run perpendicular to the running direction A of the tunnel kiln car 38. As from the figures can be seen, several rows 42 can be placed next to each other in a line on the tunnel kiln car 38. After the tunnel kiln car 38 has been loaded over its entire width in one or more rows, it is moved forward so far that the next row seen in the running direction of the tunnel kiln car is then loaded by means of the transfer gripper 40.
  • each row of roof tiles 42 is secured against tipping.
  • the spacer lugs 20 ensure a relatively large distance between the roof tiles standing upright on the tunnel kiln car, the roof tiles are optimally accessible on both sides in the subsequent drying and firing process for dry air or heating air.
  • the roof tiles placed in rows on the tunnel kiln car 38 are then moved and dried, fired and cooled by means of the tunnel kiln car 38 through the tunnel dryer 48 and the tunnel kiln 50 adjoining them.
  • the tunnel kiln cars 38 are unloaded in rows by means of a transfer gripper device of the type described with reference to FIGS. 1 and 2 and placed in rows standing vertically on a further special conveyor belt 52, the structure of which corresponds to the conveyor belt 30.
  • the fired roof tiles 18 are removed from the conveyor belt 52 and individually in cycles laid flat in their horizontal position, as indicated at 54.
  • the spacer tabs 20 are automatically separated from the roof tiles 18 by means of a separating device stylized by reference number 56.
  • the roof tiles 18 are sorted, packed and loaded in the usual way.
