Definitions

  • This invention relates to mechanical, electrical, and electronics engineering.
  • System S.p.A. an Italian machinery manufacturer, developed a tile forming press for a large format, capable of producing ceramic tiles of up to 3 meters in length.
  • System S.p.A. has detailed its technique for making patterns throughout the mass of the ceramic tiles in European Patent EP 1334811 .
  • the technique which is characterized by a double-pressing that comprises first a low pressure compacting.
  • the compacted ceramic tiles are subsequently decorated by an ink-jet system to apply, according to the design, special ceramic colors which can penetrate into the tile mass.
  • appearance of the patterns in the tile mass is somewhat partial and the level of depth of pattern penetration is not deep enough to provide the pattern to the lowest layer of the tile mass.
  • CMF S.r.1 of Italy has introduced a technique of filling tubes with a mixture of powdery materials of different characteristics and then distributing the powdery materials through openings which are of two sizes, small and large.
  • the powder distribution technique creates a continuous veining of patterns stored in a compartment which is in a position perpendicular to the plane. Once the powdery materials are fully filled and arranged in layers of the continuous veining of patterns inside the compartment, the compartment is rotated 90 degrees in order to lie parallel to the plane. The powdery materials in the desired patterns are then transferred into the mold. From this technique, the transfer of powdery materials into the mold is also problematic. It has been found that the powder mass is mixed on the tile surface, requiring the ceramic tiles to be polished after firing in order to obtain the visible veining effect of the patterns.
  • veining pattern is not continuous and appears to zigzag. Since the tubes for holding materials used have openings of only two sizes, it is impossible to control the quantity of the material relative to the changes either in dimension or width of the veining patterns.
  • EP 0 940 235 A2 discloses according to the pre-amble of claim 1, a machine for the production of tiles with variation of colour in the body, with a member which is movable between an erect position and a horizontal position, and which defines a powder filling well arranged with a powder inlet mouth.
  • the inlet mouth is turned upward when the member in the erect position to receive the powders; when the well is full, the member is taken to the horizontal position, and the bottom of the well opens to dump the powders into the mold.
  • a charging device and press for the production of tiles with striping or veining is disclosed in EP 1 043 134 A2 , with an accumulation well which stays upright during charging and dumping the powder without moving the well.
  • Other devices for forming a powder load onto a surface are disclosed in EP 1366 874 A1 and US 5,554,393 .
  • the invention is a development of a process and an invention of a device for making patterns from powdery materials or granulated powders which have the quality of a continuous flow in order to bring about the making of continuous veining of patterns extending through the entire thickness of products in a desired format and to be able to adjust or change the patterns easily during production, and more particularly concerns a method for producing the veining of patterns with a width of 1 millimeter or more.
  • the invention is to obviate the limitations and drawbacks of material mix up on the surface which entails the need for polishing after firing, or the need to suction off the mixed-up materials from the surface of the products before pressing.
  • the powdery materials or granulated powders can be either organic or inorganic substances which possess a uniform flow.
  • the process to bring about the continuous veining of desired patterns is capable of producing veining patterns with a width of 1 millimeter or more. Varying the width of veining of patterns can be done continuously, smoothly, and successfully without appreciable mixing of the powdery materials of different colors at the surface layer of the products. Therefore, the products obtained from this process are well defined and meet with the desired patterns without a further step of surface decoration, either before or after the production process.
  • the device and method for making continuous veining of patterns throughout the entire thickness of the products comprises a material distributing control cartridge (1) which is installed to be driven with reciprocating motion above an arrangement belt (11), a vertical material receiving-distributing cartridge (2) which is installed at the farthest end position of and under the arrangement belt (11), but sited above a conveyor belt (23), and a horizontal material receiving-distributing cartridge (3) which is installed on the conveyor belt (23).
  • the material distributing control cartridge (1) consists of tubes (12), which are containers for holding the material of different characteristics and different colors. There can be more than one tube depending on the different characteristics and different colors of the materials used. All of the tubes (12) are fixed but movable reciprocally on an axle (13), having the course of movement on the horizontal direction, perpendicularly to the movement direction of the arrangement belt (11). Open-close valves (14) are located at the end of the each tube (12).
  • the vertical material receiving-distributing cartridge (2) consists of a material receiving unit (20) which is a flat rectangular box. This material receiving unit (20) has two connected ridges forming first opening (21) and second opening (22). At the mouth of each opening, there is positioned first open-close flap (24) and second open-closed flab (25) respectively.
  • the vertical material receiving-distributing cartridge (2) is installed under the farthest end position of the movement of the arrangement belt (11) but sited above the conveyor belt (23) by being placed perpendicular to both the arrangement belt (11) and the conveyor belt (23), as well as perpendicular to movement directions of both belts.
  • the vertical material receiving-distributing cartridge (2) can rotate freely with reciprocating movement by having its fulcrum disposed at the mid point of the material receiving unit (20) and its rotating axle perpendicular to the material receiving unit (20).
  • the horizontal material receiving-distributing cartridge (3) consists of a flat rectangular cover sheet (30) with two ridges on opposite sides forming first exit (31) and second exit (32). At the mouth of first exit (31), there is positioned an open-close member (33); while there is positioned an open-close and excess material removal flap (34) at the second exit (32). Inside the cover sheet (30), there is positioned a pressing sheet (35).
  • the horizontal material receiving-distributing cartridge (3) is laid prone on the conveyor belt (23). The direction of the in-and-out path of materials from the horizontal material receiving-distributing cartridge (3) is the same as the movement direction of the conveyor belt (23).
  • the process for making continuous veining of desired patterns extending throughout the entire thickness of the products according to the invention comprises the following three main procedures:
  • the materials are to be distributed onto the arrangement belt (11) from the tubes (12) that move back and forth along the axel (13) above the arrangement belt (11) which is moving forward in order to control a succession of materials, the quantity of the material, and the position at which the materials are released onto the material receiving unit (20) in accordance with the predetermined patterns.
  • the apparatus which control the work in this procedure are the material distributing control cartridge (1) and the arrangement belt (11).
  • Second Procedure Allowing the material which is already distributed onto the arrangement belt to flow into the material receiving unit to bring about the patterns
  • the materials will be allowed to fall down in such a manner as to form layered patterns inside the material receiving unit (20) in accordance with the predetermined patterns, quantity, and position of the materials to form the desired patterns. From then on, the material receiving unit (20) will rotate and perpendicularly transfer the patterned materials onto the conveyor belt (23) which will move forward in order to transfer said materials from the material receiving unit (20).
  • the apparatus which control the work in this procedure are the vertical material receiving-distributing cartridge (2), the arrangement belt (11), and the conveyor belt (23).
  • the apparatus which control the work in this procedure are the horizontal material receiving-distributing cartridge (3) and the conveyor belt (23).
  • the work starts from the material distributing control cartridge (1) which performs the duty of distributing the materials onto the arrangement belt (11) in accordance with the predetermined patterns, quantity, and position of the materials through the operation of the open-close valves (14).
  • the open-close valves (14) control the distribution and the quantity of the materials while the tubes (12) are moving in the reciprocating motion on the axle (13).
  • the movement of the arrangement belt (11) determines the position at which the materials will be distributed.
  • the predetermined materials on the arrangement belt (11) After the predetermined materials on the arrangement belt (11) have moved to the farthest position of the arrangement belt (11), those materials fall into the material receiving unit (20) through the first opening (21) which remains open.
  • the materials are formed in such a manner that one layer is placed over another in accordance with the pattern, the quantity of the materials, and the position at which the predetermined patterns is created.
  • the results through this means are the same as when the materials are distributed directly from the tubes (12) to the material receiving unit (20) except that early preparation of the materials helps to increase the speed of running the machine a lot better.
  • the use of electrical and electronic instruments with high precision and accuracy, such as a servo motor, to regulate the operation of the open-close valves (14) makes the stage and degree of valve opening more continuous, precise and accurate. Suitable use results in the capability to continuously change the width of the veining patterns, as well as to produce veining with a width of 1 millimeter or more.
  • the first open-close flap (24) at the first opening (21) is closed in order to maintain the pattern and prevent leakage.
  • the material receiving unit (20) is rotated to form a 90 degree angle with its rotating axle perpendicular to the plane of the material receiving unit (20) in order to position the second opening (22) above the conveyor belt (23). Rotating 90 degrees and distributing the materials in a perpendicular fashion maintains the definition of the patterns and reduces the distortion of the surface patterns of the material.
  • the second open-close flap (25) at the second opening (22) will open to allow the materials with layered patterns to flow onto the conveyor belt (23). While the materials are flowing out, the conveyor belt (23) will move forward in order to transfer the materials from the material receiving unit (20). After the materials have flowed completely out of the material receiving unit (20), the second open-close flap (25) at the second opening (22) will be closed. Then the material receiving unit (20) will be rotated back to the starting position. The first open-close flap (24) is opened again and the first opening (21) is ready to receive a new batch.
  • the patterned materials on the conveyor belts (23) move forward to the horizontal material receiving-distributing cartridge (3) through the first exit (31). After the patterned materials move completely inside the cover sheet (30), the open-close member (33) is closed down. Then the horizontal material receiving-distributing cartridge (3) will move forward to bring the patterned materials to the pressing machine.
  • the press sheet (35) moves down to lay flat against the upper surface of the patterned materials while the patterned materials are moving towards the pressing machine so that the powdery materials around the areas are saved from dispersion which damages the surface patterns. While the horizontal material receiving-distributing cartridge (3) is moving, the conveyor belt (23) also moves in order to prevent damage to the lower layer of the patterns.
  • the forward motion of the horizontal material receiving-distributing cartridge (3) creates a compaction of the materials in the direction that is opposite to its movement. This condition results in insufficient quantity of materials which are to be filled into the mold cavities of pressing machine. Therefore, it is necessary that the open-close and excess material removal flap (34) remains open while the horizontal receiving-distributing cartridge (3) is moving, so that excess materials positioned at the second exit (32) are compacted to move adequately into the horizontal material receiving-distributing cartridge (3).
  • the horizontal material receiving-distributing cartridge (3) moves the patterned materials contained inside move backward, causing the quantity and density of the materials to increase in the direction opposite to the direction of the horizontal material receiving-distributing cartridge (3) movement.
  • the quantity of the materials is unevenly transferred to the pressing machine in such a manner that the materials are more bulky and denser at the back than the front.
  • the front portion is less thick than the back portion.
  • the pressing sheet (35) which performs the duty of pressing the bulk of the materials in accordance with this invention, is pressed down not exactly parallel to the plane of the conveyor belt (23), but is pressed down in such a manner to make an elevated angle between 0-0.5 degrees so that the quantity of the materials in the front portion are equally compensated for.
  • the exact degree of the elevation of the pressing sheet (35) depends on the quantity of the materials needed to be compensated for.
  • the pressing sheet (35) presses the materials into the mold along with the downward movement of a lower lift of the pressing machine, and the open-close and excess material removal flap (34) is closed down.
  • the open-close and excess material removal flap (34) moves in a forward direction in order to remove the excess materials. Both the open-close flap (33) and the open-close and excess material removal flap (34) are opened and the horizontal material receiving-distributing cartridge (3) moves back away from the pressing machine to be positioned on the conveyor belt (23).
  • the pressing sheet (35) moves upward and the horizontal material receiving-distributing cartridge (3) returns to the original position to start receiving a new batch of materials.
  • the finished product After having gone through the process of molding by pressing and firing, the finished product possesses the desired patterns without the necessity to polish the surface.
  • each product's patterns can be adjusted and changed in order to meet the requirement.
