TR TR TR TR DESCRIPTION VACUUMING WORKING SYSTEM Technical Field The invention is related to the core taking system used in core machines that produce sand cores in foundries in the casting industry. The invention is particularly related to the vacuum core retrieval system, which enables the sand cores produced in core machines to be vacuumed automatically by an industrial robot. Known State of the Technology In the casting industry, core production in foundries is carried out by using core sand in core machines. In the core production in question, the sand is blown with air inside the mold. In the current technique, cores are taken, turned and placed in foundries by means of mechanical, pneumatic or hydraulic grippers, and usually manually, using manpower and cranes. Due to the implementation of the core picking process in the mentioned way, unnecessary manpower is used in production and as a result, production is lost due to time loss. In addition, a large amount of core wastage in foundries occurs during manual product picking and subsequent transportation between operations (by hand or forklift). In addition, holders are generally applied by using the holes in the cores, and since the holders are worked manually, it is possible for the holders to hit the core. This causes fragile cores to break and increases the production waste rate. For this reason, in order to eliminate the problems experienced in the known state of the technique, a system that enables automatic retrieval of sand cores has arisen. In the research conducted in the literature, the document numbered EP1109004 can be cited as an example of the known state of the technique. The mentioned document relates to a process for studying the behavior of the binding systems of sand cores during casting. In the invention in question, a process is mentioned that allows the sample core to be completely immersed in a molten metal bath and the gas escaping from the sample core to be directed from the core surface and to collect the gas to determine the amount as a function of time. However, in the invention in question, a system that enables automatic taking, turning and placing of the sand core is not disclosed. As a result, the existence of the above problems and the inadequacy of existing solutions necessitated a development in the relevant technical field.

It contains the vacuum holder (80), the control panel (90) that provides power to the blower (20) and controls the system. In the cabin (10), which constitutes the carrier structure of the vacuum core taking system subject to the invention, the core is taken from the machine for surface grinding, painting, assembly, mold placement, etc. There is at least one blower (20) that produces vacuum to vacuum the sand core to be processed. The capacity of the blower (20) in question is selected depending on the weight of the sand core. The blower (20), which works with sensitive gaps, is connected to at least one vacuum filter (30) to protect it from dust. For vacuuming with the blower (20), a large valve (40) and a small valve (50) are connected to the blower (20) and the air flow is enabled to open and close. The large valve (40) and small valve (50) in question are triggered by the pneumatic directional valve (70) for the on-off operation. The vacuum provided by the blower (20) is transmitted through the vacuum hose (60). At the end of the vacuum hose (60), there is a vacuum holder (80) that vacuums the sand core in a leak-tight manner. The vacuum holder (80) in question works connected to the industrial robot. The vacuum gripper (80) connected to the industrial robot is equipped with insulation gaskets surrounding the sand core from the outside to prevent air leaks. For vacuuming, power is supplied to the blower (20) through the control panel (90) and the vacuum core receiving system is controlled.

Blower (20) is always active during operation. Surface grinding, painting, assembly, mold placement, etc. of the sand core produced in the core machine. When the vacuum holder (80) goes to the programmed position of the industrial robot to be taken from the core machine to be processed, the large valve (40) and small valve (50) are in the open position, that is, the vacuum core taking system is in the non-vacuum position. When the vacuum holder (80) reaches the position of receiving the sand core, the pneumatic directional valves (70), large valve (40) and small valve (50) are triggered in the closing direction and vacuum is provided. When vacuum is provided, the industrial robot vacuums the sand core with the vacuum provided in the vacuum holder (80), removes it from the lower core box and performs the necessary operation in line with the program for the operations to be applied. After the sand core operations are completed, the industrial robot delivers the sand core to the releasing position. The pneumatic directional valve (70) triggers the small valve (50) in the opening direction and after a short delay, the large valve (40) is triggered. By gradually releasing the vacuum in the vacuum holder (80), the product is released and the process is completed. This process is repeated in the same way to take the sand cores that are still being produced from the core machine. TR TR TR TR
