Description

The invention concerning ceramic products

  or similar, is more specifically

  for the manufacture of ceramic tiles

  that or the like, in which the tiles, after demolding

  ge, are guided to pass by a train

  rolls, by a cooking oven, as well as

  process for carrying out said method, comprising

  a feeding device, a cooking oven and a

  voyeur with rollers, which is constituted by a multiplicity

  elongated rollers and arranged at a low

  from each other and passing through the oven

Cooking.

  In the manufacture of ceramic tiles

  and especially when cooking ceramic tiles

  These conveyors consist of relatively thin cylinders resting in

  supports at both ends and driven by a tee.

  However, a roller of such a conveyor must have a diameter as large as possible, so that the tile itself has a relatively large bearing surface. In addition, relatively large diameters imply relatively large spacings of the different rollers with respect to each other. to others and again this results in a limitation of the dimension of the tiles that can be transported on such a conveyor, as far as

the smallness of their dimensions.

  By changing to relative roll diameters

  small and at a distance from these relatively

  it is necessary to take into account that the rollers

  can withstand, in the baking oven, a temperature

  relatively high and therefore a limit is

  imposed on the smallness of the rollers.

  In the installations currently in use, it is used, in front of the baking oven and the roller conveyor passing through this oven, a feeder device for placing the different tiles relative to the conveyor and relative to each other, so that

  for example a limiting edge of the tiles

  This orientation is used without exception in the known devices, because with this orientation mode relatively large number of tiles can be placed on a conveyor. with rollers

  placing them next to each other and furthermore

  cuation at the outlet end of the oven can be

relatively simple.

  The object of the invention is to establish or

  a method and a device of the kind indicated in the introduction

  so that, for a given roller conveyor, tiles can be transported with a fixed gap and with a constant roll diameter, which is significantly smaller than the existing tile size * This is essentially obtained thanks to the fact

  that at the entrance end the tiles are not

  so that one of their edges is perpendicular to the transport direction of the conveyor, but their largest extent is aligned in that direction. For square tiles, this means that the tile is oriented by one of its diagonals in the direction of transport, that is to say that it is introduced into the oven first by its tip With this arrangement can be transported

  and cook, with a pre-set roller oven, a car-

much smaller.

  The invention will be described by way of example,

  in what follows with reference to the single figure of the des-

hereinafter annexed.

  This figure shows schematically the end,

  c 8 t entry, a baking oven with conveyor to rou-

corresponding waters.

  In the figure is schematically shown a cooking oven 10 having an inlet opening 11,

  In the direction of transport, as indicated

  By arrow 16, a roll conveyor 12 consisting of a multiplicity of rollers 18, all identical, is placed in front of the oven 10. The roller conveyor

  12 passes through the baking oven 10; the provision

  tif of drive and the bearings of the different rollers

18 are not shown.

  In 13 we see schematically a device,

  acting on the tiles 14 which are on the con-

  roller voyeur, for rotating these tiles at an angle of 450 relative to the direction of transport 16, assuming that the feeder device (at 17), which is not shown, aligns the tiles 14 so as to

  that they be arranged by a limiting edge

  However, after the departure of the orientation device 13, the tiles 15 have taken an orientation such that they are directed forward by their point, that is to say that

  their diagonals is parallel to the direction of trans-

port 16.

  In the figure only three tiles 15, located one on top of the other, have been shown, and

  tiles 14, to understand the principle of

  It is understood that in a practical embodiment of the present invention the tiles 15 will be arranged closely to each other, at least

  so that their front edges are directed perpendicularly

  the direction of transport, but that the points of the various tiles are arranged forward,

  the different tiles 15 forming rows in the-

  which the various neighboring edges of tiles are

in parallel *
