Definitions

  • the present invention relates to a machine for the production of tiles with variation of color in the body.
  • the need is felt to be able to rapidly and economically produce tiles with color variations in the body.
  • this can be used to simulate the striations peculiar to natural stones or to simulate inlays.
  • the general purpose of the present invention is to overcome the above shortcomings by supplying a simple and economical machine which would allow rapid production of tiles with color variations in the body with well controllable and repeatable results.
  • a machine for the production of tiles pressed with color variation in the body of the powders comprising a member which is movable between an erect position and a reclined position with the member defining a powder filling well which is arranged with a mouth for inlet thereto of the powders turned upward when the member is in an erect position to receive the powders poured therein from a delivery unit with the member also comprising means for pouring from the well which are controllable when the member is in a reclined position to pour the powders from the well into a pressing mold.
  • Fig. 1 shows a machine indicated as a whole by reference number 10 for the production of tiles.
  • the machine comprises a section 11 for loading the powder and a section 12 for pressing.
  • the pressing section comprises a mold 13 and a press 14. Mold and press are virtually prior art and will not be further described or shown.
  • the filling section comprises a filling truck 15 which by means of an actuator 16 is movable between a retracted or powder reception position (shown in Fig. 1) and an advanced or powder pouring position (shown in Fig. 4).
  • the truck can comprise mold cleaning means 17 in front which run on the upper surface of the mold when the truck moves between its two positions.
  • the filling section comprises a unit 18 for powder reception mounted on the truck to run with it and comprising a powder reception member 19 which can overturn around an axis 20 to change from an erect position (shown in Fig. 1) to a reclined position (shown in Fig. 3).
  • the member 19 defines a well 21 closed by a movable bottom 22 into which a delivery unit 23 pours through an upper mouth 39 of the well in erect position the powders to be pressed as clarified below.
  • the bottom 22 can be made to run by means of an actuator 24 to dump the powder contained in the well.
  • FIG. 2 overturning of the member 19 is controlled by a pulley 25 integral with the overturning axis and is driven by a motorized belt 26.
  • the box bottom 22 runs on guides 27 by means of wheels 28.
  • Fig. 2 For the sake of simplicity only one half of the device is shown in Fig. 2. It is understood that the partial view of Fig. 2 represents symmetrical mirror images of the device centered on the axis 29.
  • the overturning member 18 In erect position the overturning member 18 can be inclined towards the reclining position with an angle between 90° and 45° and advantageously between 60° and 80° to the horizontal as may be seen in Fig. 1.
  • the machine in use is in the position shown in Fig. 1.
  • the delivery unit 23 unloads the powder to be pressed into the well 21.
  • the well 21 can be filled with a body of powders of different colors so as to form striations or designs in the body.
  • the slight thickness of the well permits satisfactory accuracy in powder distribution.
  • the overturning member 18 When the well 21 is full the overturning member 18 is taken to the horizontal position as shown in Fig. 3 and the truck 15 advances to take the well 21 vertically over the mold as shown in Fig. 4. After reaching this position the dumping means formed by the box 22 are driven by the actuator 24 so as to open the bottom of the well and dump the powders into the mold. Then the truck backs off and the box advances so as to take the filling unit into the initial position shown in Fig. 3 and then Fig. 1. The press is then operated to press the powder in the mold in accordance with the prior art.
  • Fig. 6 shows a possible embodiment of the delivery unit 23.
  • the delivery unit comprises a head 30 running on command along tracks 31 parallel to the inlet mouth of the well 21.
  • the head 30 has ducts 32 inside it for controlled delivery of different powders from the outlet mouth 33.
  • By commanding running of the head along the guides and simultaneous delivery of selected powders it is possible to secure desired designs and striations layer after layer.
  • baffles 34 appropriately shaped for separation of various zones of the well so as to obtain more accurate designs or zones with different powder distribution.
  • Fig. 7 shows a variant of the delivery unit (still indicated by reference number 23). It comprises a multiple delivery head 35 made up of a plurality of delivery units each for controlled delivery of a predetermined powder.
  • the head 35 is fixed and dumps onto a revolving belt 36 which conveys the powder received towards a dumping end 37.
  • the belt is parallel to the mouth of the well 21 and is movable at least in its dumping end 37 along the extension of the mouth e.g. on guides 38.
  • the dumping end moves along the entire extension of the mouth of the well 21 while an upper part of belt always remains underneath the delivery mouths of the head 35. In this manner the head can be used to deliver the various powders onto the belt in predetermined quantities and sequence. Running of the delivery end on the well then pours the powders from the running belt into the well.
  • Fig. 8 shows a variant embodiment of the powder reception member.
  • members similar to those of Fig. 1 are indicated by the same numbers increased by one hundred.
  • a powder reception unit 118 mounted on the truck 115 to run therewith and comprising a powder reception member 119 which can be overturned around an axis 120 to change from an erect position (shown in solid lines) and an extended position (shown in broken lines) by means of a powered pulley 125.
  • the member 119 defines a well 121 closed on one face with a powered running belt 122 onto which a delivery unit 23 identical to those described above dumps the powders through a mouth 139.
  • the member 119 When the well is full the member 119 is brought into a horizontal position and the belt 121 is started to convey the powder from the well to dump it into the mold.
  • the truck 115 advances simultaneously so as to move the dumping end 140 along the mold and fill it completely.
  • Figs. 9 and 10 show another variant embodiment of the delivery unit (again indicated by reference number 23).
  • Unit 23 can be applied to any of the embodiments shown in the other figures.
  • the unit comprises a main hopper 251 and a secondary hopper 252 both of which are equipped with respective capped gates 253, 254 controlled by actuators 255, 256.
  • the figures show four mouths arranged at the vertices of a square.
  • Powders for graining the tile reach the secondary hopper 256 through a duct 259.
  • the head 23 is powered to run with wheels 262, 263 along guide tracks 260, 261 arranged horizontally parallel to the upper filling mouth of the well 21.
  • the head 23 During movement the head 23 dumps onto an inclined plane or chute 250 which conveys the powders into the well 21.
  • the head runs forward and backward along the tracks while it dumps selected colors filling the well with successive layers.
  • the powder dumped from the main hopper creates the main body of the tile while the powder dumped from the secondary hopper creates the finer graining. This helps give a more natural appearance to the finished product.
  • the machine could comprise means of cleaning, delivery from the mold, conveyance of the pressed tile et cetera as easily imaginable by one skilled in the art.
  • the multiple head could also be made up of a plurality of individual heads running independently on the mouth of the well.
