Description

A TIRE FRAGMENTATION MACHINE

TECHNICAL FIELD

The invention relates to at least one tire fragmentation machine comprising at least one tire chamber on which the tire can be positioned and at least one cutter that can be at least partially moved in the at least one tire chamber, to be used particularly in the fragmentation of the tires used in vehicles.

PRIOR ART

The tire is one of the important parts of the vehicle, which is designed to hold compressed air in it, ensures the vehicle's contact with the ground by being mounted on the rim, has rubber, steel wires and many chemicals in its composition, and is produced with a process that requires high technology. The tire carries a certain load on it by maintaining the necessary high pressure air. It is important that the tire is inflated with air at the appropriate pressure to be able to perform this task in the geometry for which it is designed.

Today, end-of-life vehicle tires, besides being abundant, are of the nature of a worthless waste. Furthermore, it affects human health and natural balance negatively by causing environmental pollution. One of the most effective ways to eliminate these problems is to reprocess the waste tires and to use them in the different application in the industry.

Every year millions of tires become scrap around the world. There are two important environmental damages in the places where scrap tires are piled up and thrown away. The first one of these is the severe fires in these piles and the other is the possibility of spreading diseases that are very threatening for the society due to the insects that have the opportunity to reproduce easily in these piles. Diseases caused by insects breeding in these piles are seen especially after rains. In Ohio, reasons of 80% of child diseases appear to be the nearby piles of scrap tires.

In terms of the environment, recycling of scrap tires is important for the sustainability of the world's ecosystem. Recycling, energy recovery or facilitating the disposal of these begin with the reduction of scrap tires. There is only one blade in the tire cutting machines available in the industry, and cutting is done in the horizontal plane with the help of at least one personnel, with long-lasting and dangerous operations. In this type of machines, there is a hydraulic piston that moves the said cutting blade. The hydraulic piston presses the blade to the tire by applying force repeatedly, and the cutting happens. In this system, multiple blade strokes are applied to cut a scrap tire. In this case, the scrap tire cutting process is prolonged and the efficiency decreases.

In alternative embodiments, scrap tire cutting machines in which multiple blade structures are used are also known. However, in these embodiments, there are problems such as sizing the tire and accordingly aligning the blades. In addition, there is a risk that the scrap tire cut from multiple places will scatter around and harm the operator, and safety weaknesses will occur. The tire scattering around can damage the operator or the machine. In addition, the time consuming of scrap tire transfer in machines used in the current technique also emerges as a technical problem. The operator giving the tire to the machine both affects the employee health negatively and may cause occupational accidents.

As a result, all the aforementioned problems have made making an innovation in the relevant technical field necessary.

In this detailed description, the subject of the invention is described with non-limiting examples only for better understanding of the subject.

In Figure 1 , a representative perspective view of the tire fragmentation machine (1), which is the subject of the invention, is given. According to this, the tire fragmentation machine (1), which is the subject of the invention, substantially helps to divide tires (60) used in the wheels to small pieces. The said tire (60) is a rubber-based element and one of the important parts of the vehicle, which is designed to hold compressed air in it, ensures the vehicle's contact with the ground by being mounted on the rim. As the tire (60) becomes inoperable, especially in long-term use, the need to transform it into different materials arises. In this case, the steel wires in the tire (60) are removed and the tire is reduced to small sizes by means of the tire fragmentation machine (1).

In order to do this, the tire fragmentation machine (1 ) has at least one body (10), at least one tire chamber (30) positioned on the said body (10), and at least one cutter (20) which can move at least partially within the said tire chamber (30). Said tire chamber (30) is sized such that at least one tire (60) is positioned inside, and it is associated with the cutter (20). Preferably, the tire (60) can be positioned upright in the tire chamber (30). Said cutter (20) enters and exits the tire chamber (30) at least partially, and splits the tire (60) into small pieces.

In Figure 2, a representative side view of the tire fragmentation machine (1), which is the subject of the invention, is given, when we detail the invention according to this, in the tire chamber (30), there is at least one first wall (31 ) and at least one second wall (33) positioned opposite to each other. There is a cutter gap (32) on at least one of said first wall (31) and said second wall (33) and at least one cutter slot (34) on the other. The cutter (20) can move within the tire chamber (30) by passing through the said cutter gap (32). Said cutter slot (34) is aligned mutually with the cutter gap (32). The cutter slot (34) is an opening or hollowshaped element provided on the wall on which it is positioned, and it elongates and prevents cutting errors when the tire (60) is cut by the cutter (20), and allows the cut tire (60) parts to be completely separated from one another.

In Figure 3, a representative perspective view of the cutter (20) in the tire fragmentation machine (1) is given. According to this, the cutter (20) has at least one blade (21) on it and at least one first drive element (23) to move the said blade (21). In a possible embodiment of the invention, said blade (21 ) can be obtained from a plurality of steel materials on the cutter (20) . In this way, it allows the tire (60) to be subjected to multiple cuts easily with a single cutting action. Preferably, four pieces are provided between the blades (21) at vertical angles when viewed from the opposite side. In the preferred embodiment of the invention, said first drive element (23) is a hydraulic driven element. However, the invention is not limited to this, and in alternative embodiments, it can also be a drive element that can be powered with different energy sources. In addition, there is at least one protection cover (22) on the cutter (20), configured to at least partially enclose the cutter (20). Said protection cover (22) acts as a safety element to prevent the tire (60) parts from scattering around and damaging the environment during the cutting of the tire (60) by the blades (21) on the cutter (20).

Holding the tire (60) in the tire chamber (30) is provided by at least one tire holding device (40). In Figure 4, a representative perspective view of the tire holding device (40) in the tire fragmentation machine (1) is given. According to this, the tire holding device (40) is configured to make sure that the tire (60) is held in the tire chamber (30), and in the same time to detect values such as the weight and size of the tire (60). The tire holding device (40) has at least one first arm (41) and at least one second arm (42) to ensure that the tire is held in the tire chamber (30). In the preferred embodiment of the invention, the said first arm (41) and the said second arm (42) are positioned mutually to be parallel to each other. In the tire holding device (40), there is at least one support group (44) on which the first arm (41 ) and the second arm (42) are located. Said support group (44) is configured to at least partially move the said first arm (41 ) and the said second arm (42) in a first axis (I) and in a second axis (II). There is at least one first support element (441) and the said first support element (441) on the support group (44). Said second support member (442) is associated on the said first support member (441) to be able to move in the first axis (I). The first arm (41) and the second arm (42) are positioned on the second support element (442), the movement in the second axis (II) relative to each other is allowed. To achieve this, the first arm (41 ) is connected with at least one first rail (444) and the second arm (42) is connected with at least one second rail (445). Said first rail (444) and said second rail (445) are substantially mutually positioned in a slot (443) provided on the second support member (442). There is substantially a threaded surface on the first rail (444) and the second rail (445) and it is associated with at least one first gear wheel (446). Rotating the said first gear wheel (446) around itself by at least one drive element (not shown in the figures), the first rail (444) and the second rail (445) move in directions opposite to each other. The first rail (444) and the second rail (445), which move in the opposite direction, also bring the first arm (41 ) and second arm (42) closer and further apart on the second axis (II) relative to each other. By this way, it can be positioned in different ways depending on the size of the tire (60) and stability is provided in the tire chamber (30).

In Figure 5, a representative zoomed perspective view of the tire holding device (40) in the tire fragmentation machine (I) is given. In the tire holding device (40), the first arm (41 ) and the second arm (42) can also be moved in the first axis (I). To achieve this, there is at least one slide part (43) on at least one of the first arm (41 ) and the second arm (42). In a possible embodiment of the invention, said slide part (43) is provided on both arms. The slide part (43) is substantially the threaded part provided on the arms. This slide part (43) is associated with at least one second gear wheel (447). Said second gear wheel (447) is positioned substantially perpendicular to the extension direction of the first arm (41) and the second arm (42). By rotating the second gear wheel (447) around itself by at least one second drive element (448), it enables the first arm (41 ) and the second arm (42) to move in the direction of the first axis (I). In a possible embodiment of the invention, said second drive element (448) can be an electric motor. With the movement of the tire holding device (40) in the first axis (I), it is ensured that the tire (60) is removed from the tire chamber (30) after cutting.

At least one first sensor (50) is located on at least one of the first arm (41) and the second arm (42) in the tire holding device (1). Said first sensor (50) is preferably provided as two sensors, one on the first arm (41) and one on the second arm (42), facing the tire (60). First sensor (50) determines the size of the weight force applied on the first arm (41) and the second arm (42). The result of the weight determination of the tire (60) is transmitted to at least one control unit (not shown in the figures). Said control unit activates the first drive element (23) in order to apply a predetermined amount of force to the cutter (20) according to the weight of the tire (60). By this way, the excess energy waste is prevented. In addition, it is possible to detect the tire (60) of different sizes. Depending on this determination, it is also possible to change the distance between the first arm (41) and the second arm (42).

In a possible usage scenario of the invention, when the tires (60) enter the tire fragmentation machine (1), they are met by the tire holding device (40) in the tire chamber (30). The weight of the tire (60) is determined by the first sensor (50) and at the same time, the force that the first drive element (23) will exert on the cutter (20) is determined by the control unit. As a result, multiple blades (21 ) positioned on the cutter (20) pass through the cutter opening (32) and cut the tire (60). The cutting command can also be given by the operator with a control handle (not shown in the figures). The cut tire (60) is poured with the effect of gravity after the arms are removed from the tire chamber (30) in the first axis (I). In a possible embodiment of the invention, a conveyor line can be located in the lower neighbourhood of the tire chamber (30) in order to integrate the tire fragmentation machine (1 ) with the production lines. The cut tire (60) pieces can be transported to the next processing step by means of this conveyor line.

In other possible embodiments of the invention, there may be at least one second sensor (not shown in the figures) on the tire fragmentation machine (1 ). Said second sensor is substantially a light sensor and detects the presence of the tire (60) in the tire chamber (30). By this way, even if the first drive element (23) is triggered manually, its operation is prevented and no energy is wasted. In addition, the tire fragmentation machine (1 ) can be integrated with a cloud-based system. The data received from the sensors on the tire fragmentation machine (1) can be processed by the control unit and transmitted to the cloudbased system, and the technical information about the tire fragmentation machine (1) can be accessed remotely. In addition, the tire fragmentation machine (1 ) can also be controlled remotely.

With all this structure, the fragmentation of scrap tires (60) is accelerated by the multi-blade (21 ) configuration and optimized together with the tire holding device (40). With this structure, a high rate of efficiency increase has been achieved in industrial production compared to the machines known in the prior art. In addition to the increase in efficiency, the load on the operator is reduced and occupational safety is increased.

The protection scope of the invention is specified in the attached claims and cannot be limited to what is described in this detailed description for the purpose of illustration. Because it is clear that a person skilled in the art can present similar embodiments in the light of what has been explained above without departing from the main theme of the invention.
