Definitions

  • This invention relates to mechanical, electrical, and electronics engineering, more specifically, a device for making a continuous veining of desired pattern in a ceramic tile using powdery or granular material as described in the preamble of claim 1, as well as a corresponding process using the device of claim 1.
  • 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 EP 1334811 .
  • the technique 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 used for holding materials have openings on 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.
  • the device according to the mentioned European application comprises a material distributing control cartridge which consists of multiple tubes which act as a container for holding the powder or granulated materials for making the tiles. All of the tubes are fixed but movable reciprocally on an axle having the course of movement on the horizontal direction, perpendicular to the movement direction of the arrangement belt. The materials are then released through open-closed valves fitted at the end of the tubes on the arrangement belt and subsequently into the vertical material receiving-distributing cartridge to form the desired pattern. Once the vertical material receiving-distributing cartridge is filled, the vertical material receiving-distributing cartridge is rotated 90 degrees to horizontally discharge the patterned materials onto the conveyer belts. The discharged patterned materials are then guide-fed into the horizontal material receiving-distributing unit bringing the patterned materials toward the pressing station to press the patterned materials into a tile.
  • Document WO 2005/068146 A2 describes a method or plant for prearranging powders for forming ceramic tiles or slabs which comprises means for feeding the powders including three powder conduits and a powder loading hopper, a vertical hopper and a movable fall-on surface positioned below the hopper- One of the faces of the vertical hopper can consist of a vertical portion of an endless movable belt.
  • the present invention relates to a device and a process as defined in the independent claims of making continuous veining of desired patterns extending through the entire thickness of the products from powdery materials or granulated powders employing a device developed therefor.
  • the powdery materials or granulated powders can be either organic or inorganic substances which possess a continuous and uniform flow.
  • the process is to bring about the continuous veining of desired patterns by varying the width of veining of patterns which 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. However, if desired, the product may objectively be subjected to further beautifying or decorating processes to enhance the beauty or value of the product.
  • the invention is an improved process and 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.
  • the invention aims to obviate the limitations of the pattern created by the materials distributing control cartridge and drawbacks of irregularities of the pattern while transferring the patterned material from the vertical.
  • the device and method for making continuous veining of patterns throughout the entire thickness of the products comprises a material distributing control cartridge (10) which is installed to be driven with reciprocating motion above an arrangement belt (20), a vertical material receiving-distributing cartridge (30) which is installed at the farthest end position of and under the arrangement belt (20), but situated above a conveyor belt (40), and a horizontal material receiving-distributing cartridge (50) which is installed on the conveyor belt (40).
  • a material distributing control cartridge 10 which is installed to be driven with reciprocating motion above an arrangement belt (20)
  • a vertical material receiving-distributing cartridge (30) which is installed at the farthest end position of and under the arrangement belt (20), but situated above a conveyor belt (40)
  • a horizontal material receiving-distributing cartridge (50) which is installed on the conveyor belt (40).
  • the material distributing control cartridge (10) consists of more than one tube (12), which are containers for holding the material of different characteristics and different colors. There can be more than one tube (12) depending on the different characteristics and different colors of the materials used.
  • the material distributing control cartridge is capable of moving in multi-directions as shown in Fig. 2 . All of the tubes (12) are movable reciprocally on an axle (14) (support beam) that is able to rotate in multi-directions, having the course of movement perpendicular to the movement direction of the arrangement belt (20). Open-close valves (16) are located at the end of each tube (12).
  • the fact that the material distributing control cartridge (10) is able to rotate will increase the range of pattern as the tubes (12) will now be able to form veins with curved, circular, diagonal, or free-form characters.
  • the material distributing control cartridge (10) is further equipped with a material distributing tray (60).
  • open-close is meant to describe devices which can be controlled (switched) between an open and closed state, such as a shutter.
  • An open-close means will open or close in accordance with the stored data, i.e., in response to the control program.
  • the material distributing tray (60) is located away from (i.e., at a distance to) the tubes (12) but above the arrangement belts (20) as with the tubes (12).
  • the material distributing tray (60) is situated between two arms (62) of an axle (not shown). Each arm (62) has an outer sleeve (64) which is capable of moving up and down along the arm (62) and relative to the arrangement belt (20).
  • the material distributing tray (60) is capable of holding a large quantity of the materials released from a plurality of delivering means (66) similar to the tubes (12) of the material distributing control cartridge (10), but preferably larger in size.
  • the material distributing tray (60) comprises a first tray (68) and a second tray (70), wherein the first tray (68) is situated on top, i.e., farther above relative to the second tray (70) while its bottom region is situated within the top portion of the second tray (70).
  • the bottom of both the first tray (68) and the second tray (70) has an open-closed flap (72, 73).
  • the second tray (70) is connected to the sleeves (64) of the arms (62) by joint members (74) enabling to second tray (70) to move up or down along the arm (62).
  • the sleeves (64) of the arms (62) are capable of moving up and down along the arms (62) such that the height of the second tray (70) can be altered relative to the arrangement belt (20) so as to bring the second tray (70) closer to or further away from the arrangement belt (20).
  • the movement of each of the sleeves (64) can be adjusted independently from each other as required allowing the second tray (70) to move closer to or further away from the arrangement belt (20) and/or to be positioned level and/or tilted left or right as required.
  • a pattern regulating sensor (80) is also provided.
  • the pattern regulating sensor (80) (“the sensor") is positioned such that it can scan the pattern forming inside the vertical material receiving-distributing cartridge (30) to read the pattern values (pre-coded values which are predetermined in order to produce a desired pattern). More preferably, it is positioned above the vertical material receiving-distributing cartridge (30).
  • the sensor (80) is linked to the software application which records pre-coded values of the desired pattern which in turn control the operation mechanism of the material distributing control cartridge (10) as well as the material distributing tray (60).
  • the material distributing control cartridge (10) as well as the material distributing tray (60) dispense the materials in accordance with the pre-coded values to form the desired pattern.
  • deviation of the pattern may be experienced due to inconsistency of factors such as flow rate of the materials, amount of material being dispensed, the degree of tilting of the second tray (70), etc.
  • the sensor (80) would scan for values, for example, the slope, or curve values of the pattern being formed against the set values. If discrepancies are detected, the sensor (80) will transmit the information to the control unit which will cause the material distributing control cartridge (10) and/or the material distributing tray (60) to recalibrate to bring the values back to the set values.
  • Fig. 6 shows an example of the pattern being formed inside the vertical material receiving-distributing cartridge (30) which is made of layers of various sizes of curvy sloped veins arranged in an alternating manner. If the value of the slope detected by the sensor (80) does not match with the set value, the sensor (80) will send the detected value to the control unit to recalibrate or adjust the degree of tilting of the second tray (70) accordingly to meet the set value.
  • the degree of tilting should always correspond to the pre-coded values of the desired pattern design as well as the slope of the last batch of materials forming a pattern inside the vertical material receiving-distributing cartridge (30). This feature will ensure the consistency of the pattern.
  • the present invention further comprises the material distributing tray (60).
  • the material distributing tray (60) will shorten the time required for the materials to fill the vertical material receiving-distributing cartridge (30), in comparison to the device with a material distributing control cartridge (10) alone and without the material distributing tray (60) because the material distributing tray (60) will be able to dispense a load faster and with larger quantity of the material onto the arrangement belt (20). Thus, production volume over time is higher.
  • the feature of having material distributing tray (60) is also particularly useful when a pattern with one single color and/or characteristic of large area of single color alternated with smaller vein(s) of color(s) is desired.
  • the material distributing tray (60) may be located before or after the material control cartridge (10).
  • the vertical material receiving-distributing cartridge (30) is a flat rectangular box installed under the farthest end position of the movement of the arrangement belt (20) but situated above the conveyor belt (40) by being placed perpendicular to both the arrangement belt (20) and the conveyor belt (40), as well as perpendicular to movement directions of both belts.
  • This vertical material receiving-distributing unit (30) has two connected ridges forming first opening (32) and second opening (34).
  • the mouth of first opening (32) is formed into a slant lip wherein its upper part is wider than its lower part so as to facilitate receiving of the materials from the arrangement belt (20).
  • the mouth of the second opening (34) also has a lip slightly bent forward to allow that the material easily glides onto the conveyer belt (40).
  • the vertical material receiving-distributing unit (30) is configured such that at least one of its sidewalls, preferably the sidewall with large surface area, is able to move in a loop, similar to a conveyer.
  • the moveable sidewall is set to drive in the same direction with the movement of the materials discharging from the vertical material receiving-distributing cartridge (30). If tiles or slabs with greater thickness are desired, it is desirable to provide the vertical material receiving-distributing cartridge (30) with two opposing movable walls.
  • the movable sidewall helps to reduce friction between the material granules and the wall surface, thus discharging the patterned materials onto the conveyer belt (40) is easier and with minimal dispersion of patterned materials. Thus, the formed pattern is maintained. Accordingly, with the use of the vertical material receiving-distributing cartridge (30) having movable sidewalls, a 90-degree turn of the material receiving unit is no longer necessary. Consequently, irregularities or damages to the pattern are reduced.
  • the horizontal material receiving-distributing cartridge (50) consists of a flat rectangular cover sheet (51) with two ridges on opposite sides forming first exit (52) and second exit (53).
  • An open-close member (54) is positioned at the mouth of the first exit (52), while an open-close and excess material removal flap (55) is positioned at the second exit (53).
  • the horizontal material receiving-distributing cartridge (50) is laid prone on the conveyor belt (40). The direction of the in-and-out path of materials from the horizontal material receiving-distributing cartridge (50) is the same as the movement direction of the conveyor belt (40).
  • 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 stages:
  • the work starts from the material distributing control cartridge (10) in combination with the material distributing tray (60) which performs the duty of distributing the materials onto the arrangement belt (20) in accordance with the predetermined patterns, quantity, and position of the materials.
  • the material which will form smaller veins or finer patterns will be distributed through the operation of the open-close valves (16) of the tubes (12).
  • the open-close valves (16) control the distribution and the quantity of the materials while the tubes (12) are moving in the reciprocating motion on the axle (14).
  • the movement of the arrangement belt (20) determines the position at which the materials will be distributed.
  • the material which will form larger veins or chunky patterns will be distributed by the operation of the material distributing tray (60). As shown in Fig.
  • the materials are fed into the first tray (68); at this stage the open-close flap (72) at the bottom of the first tray (68) is in a closed state. Thereafter, the open-closed flap (72) at the bottom of the first tray (68) will open and discharge a specified amount of the materials into the second tray (70) while the open-close flap (73) at the bottom of the second tray (70) is in a closed state.
  • the materials are being dispensed from the material distributing control cartridge (10) and the material distributing tray (60) in accordance with the pre-coded values. If the desired pattern involves veins of material arranged in slopes as shown in Fig. 5 , the value of the slope will be pre-coded in the software application.
  • the pre-coded slope values will correlate with the degree of tilting of the second tray (while in production, the sensor (80) will simultaneously detect the slope value of the material inside the vertical material receiving-distributing cartridge (30) as shown in Fig. 6 ). The detected value is checked against the set value. If there is discrepancy, the control unit will recalibrate and cause the second tray (70) to tilt to the determined value to maintain the desired pattern. This is to ensure the consistency of the pattern.
  • the materials are dispensed from the first tray (68) (by opening the open-close flap (72) into the second tray (70) while the second tray (70) is tilted to the desired degree while the open-close flap (73) at the second tray (70) remains closed.
  • the open-close flap (72) at the first tray will close. Thereafter, the second tray (70) will be adjusted to positioned parallel to the arrangement belt (20). The second tray (70) will then move toward the arrangement belt (20), while remaining parallel to the arrangement (20), through the movement of the sleeves (64) on the arms (62). Once a desired distance between the bottom of the second tray (70) and the arrangement belt (20) is reached, the open-closed flap (73) at the bottom of the second tray (70) will open and discharge the materials onto the arrangement belt (20). Lowering the second tray (70) toward the arrangement belt (20) prior to dispensing the materials will reduce dispersion of the materials. Thereafter, the empty second tray (70) will move up toward the first tray (68) and resume the position ready to receive a new batch of materials from the first tray (68).
  • the open-close flap (72, 73) at the bottom of the material distributing tray (60) controls the distribution and the quantity of the materials in accordance with the predetermined pattern.
  • the pattern is brought about by alternating ranges of smaller veins alternated with a large vein. This is achieved by having the tubes (12) distribute the materials onto the arrangement belt (20) in the required amount and position to form the desired veins as the materials move along the arrangement belt (20). After the material has moved passed the material distributing tray (30), the open-close flap (73) at the bottom of the second tray (70) will open and discharge the materials contained therein onto the arrangement belt (20).
  • the predetermined materials on the arrangement belt (20) After the predetermined materials on the arrangement belt (20) have moved to the farthest position of the arrangement belt (20), those materials fall into the vertical material receiving-distributing cartridge (30) through the first opening (32) which remains open. The process is repeated.
  • the materials inside the vertical material receiving-distributing cartridge (30) 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 of the earlier version except that when a desired pattern is composed of a combination of small veins and large veins, distribution of materials to form large veins by using the material distributing tray (60) increases the speed of production as the vertical material receiving-distributing cartridge (30) will be filled faster. Further, with the help of the movement of the vertical material receiving-distributing cartridge's walls, the patterned material is smoothly and continuously transferred onto the conveyer belt (40) without requiring a 90-degree rotation. The ability to transfer the patterned material onto the conveyer belt (40) without requiring a 90-degree rotation also helps to reduce separation of the pattern and irregularity of the pattern caused by dispersion of the materials during transferring.
  • the process according to the present invention better maintain the pattern, the time which would normally be required for the prior version of the vertical material receiving-distributing cartridge to turn and then transfer the material and resume its position is cut. Consequently, the volume of the production is increased.
  • definition of the patterns and width of the veining patterns depend on the quantity of the materials deposited onto the arrangement belt (20)
  • the use of electrical and electronic instruments with high precision and accuracy, such as a servomotor to regulate the operation of the open-close valves (16) 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 second open-close flap (35) at the second opening (34) will open and the movable walls will activate to allow the materials with layered patterns to flow onto the conveyor belt (40). While the materials are flowing out, the first opening (32) of the vertical material receiving-distributing cartridge (30) remains open and continues to receive materials from the arrangement belts (20).
  • the patterned materials on the conveyor belts (40) move forward to the horizontal material receiving-distributing cartridge (50) through the first exit (52). After the patterned materials move completely inside the cover sheet (51), the open-close member (54) is closed down. Then the horizontal material receiving-distributing cartridge (50) will move forward to bring the patterned materials to the pressing machine.
  • the pressing sheet (56) 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 (50) is moving, the conveyor belt (40) also moves in order to prevent damage to the lower layer of the patterns.
  • the forward motion of the horizontal material receiving-distributing cartridge (50) 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 the pressing machine. Therefore, it is highly beneficial that the open-close and excess material removal flap (55) remains open while the horizontal receiving-distributing cartridge (50) is moving, so that excess materials positioned at the second exit (53) are compacted to move adequately into the horizontal material receiving-distributing cartridge (50). In addition, while the horizontal material receiving-distributing cartridge (50) 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 (50) 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 (56) 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 (40), 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 is equally compensated for.
  • the exact degree of the elevation of the pressing sheet (56) depends on the quantity of the materials needed to be compensated for.
  • the pressing sheet (56) 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 (55) is closed down.
  • the open-close and excess material removal flap (55) moves in a forward direction in order to remove the excess materials.
  • Both the open-close flap (54) and the open-close and excess material removal flap (55) are opened and the horizontal material receiving-distributing cartridge (50) moves back away from the pressing machine to be positioned on the conveyor belt (40).
  • the pressing sheet (56) moves upward and the horizontal material receiving-distributing cartridge (50) 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.
