[0003] TECHNICAL FIELD

[0004] The invention relates to a plansifter optical motion control system developed to automatically stop the operation of the machine in case the plansifter hanger rods, which provide the connection of the machine body to the ceiling in the working area, break or the machine body slides on the rods.

[0005] PRIOR ART

[0006] Plansifters used in mills are critical pieces of equipment that separate materials by size to ensure that milled grain and flour mixtures are of a certain fineness and quality standards. Using layers with different sifter diameters, these machines vibrate the material through the sifter and allow pieces that meet certain size criteria to pass through to the lower layers, while keeping larger or unwanted pieces on the surface. In this way, plansifters ensure a homogeneous product with the desired quality, increase production efficiency and guarantee that the end product meets standards.

[0007] In plansifters, sifter hanger bars (or hanger bars) are one of the critical components used to ensure the correct operation of the sifter. The main task of these bars is to carry and support the frame of the sifter frame or sifter. Sifter hanger bars allow the sifter to smoothly make vibratory movements, enabling effective separation and classification of materials.

[0008] The hanger rods contribute to the stable and balanced operation of the sifter. The stability of the sifter is critical to ensure that materials pass through the sifter correctly and that unwanted particles can be separated. The hanger rods fix the sifter to the ceiling and prevent any instability during the movement of the sifter. In this way, the efficiency of the sifting process is increased while preventing the sifter from moving irregularly and falling down.

[0009] Steel hanger ropes are used in addition to the hanger rods in order to prevent the plansifter from falling to the floor by separating from the ceiling in case of breakage of the sifter hanger rods in the plansifter. The steel hanger ropes, which are connected without tension so that there is no load on the plansifter during normal operation of the plansifter, prevent or slow down the fall of the plansifter to the ground by meeting the load in case the hanger rods break for any reason or the plansifter slides downwards on the rods.

[0010] In the event of a breakage of the hanger rods that connect the body to the ceiling in the plansifter, the plansifter can continue to operate, although the downward load can be met by the steel hanger ropes. Due to the high circular motion of the plansifter, this type of hanger bar breakage may result in both excessive damage to the machine and a high risk of accident in the working environment. For this reason, it is of great importance to stop the operation of the plansifter immediately in case the hanger rods break and the working order is disrupted.

[0011] In the present technique, studies are carried out on different techniques for controlling the system in case of breakage of the hanger rods in the plansifter or disruption of the working order of the plansifter. In the document with file number CN117680356A, a control mechanism developed to alert the system of an abnormal level difference that may occur between the magnetic sensors placed in the opposite horizontal plane on the plates to which the feed inlets are connected on a square plansifter and the feed plates is mentioned.

[0012] The plansifter described in the document CN215964625 in the available technical literature mentions the hanger rods and steel rope to which the body is attached. The document only mentions the use of a sensor for an irregular rotational speed on the mechanism that provides the rotational movement in the machine, but does not mention any additional safety measures in case the plansifter falls or slips on the hanger rods.

[0013] The document CN204817167 in the available technical literature mentions a mechanical locking system developed to be used in the connection of the hanger bars in the plansifter. There is no mention of any additional safety precautions in case the plansifter falls or slips on the hanger bars. BRIEF DESCRIPTION OF THE INVENTION

[0014] The inventive plansifter optical motion control system has been developed to automatically stop the operation of the machine in case of breakage of the plansifter hanger rods, which provide the connection of the machine body to the ceiling in the working area of the plansifters, or in case the machine body slides on the rods.

[0015] In the developed Plansifter optical motion control system, as a result of the detection of the beam (5) formed by the optical sensor (4) positioned on the Plansifter body (2), which is connected to the ceiling part of the working area by means of hanger rods (2.1 ), by the sensor response plate (6) connected on the machine and again by means of the optical sensor (4), it is checked whether the Plansifter body (2) is in its normal working order and position. Depending on the disruption of the oscillating movement of the machine body (2) in the horizontal axis or the change of the reflection direction of the beam (5) formed by the optical sensor (4) depending on the downward falling movement of the body (2), the position change is notified to the operation and the operation of the Plansifter is automatically stopped to eliminate the greater malfunction and safety threat.

[0016] With the developed Plansifter optical motion control system, it is checked whether the oscillating movement of the Plansifter body (2) on the horizontal axis occurs under normal operating conditions, and the change in the vertical position of the Plansifter body (2) can be detected at the same time as a result of the breakage of the hanger rods (2.1 ) or the sliding of the body (2) on the rods (2.1 ).

[0027] DETAILED DESCRIPTION OF THE INVENTION

[0028] The Plansifter optical motion control system, which is the subject of the invention, is developed to automatically stop the operation of the machine in the event that the Plansifter hanger rods, which provide the connection of the machine body to the ceiling in the working area of the Plansifters, break or the machine body slides on the rods; It includes the sensor connection arm (3) connected to the ceiling hanger body (1 ) on the Plansifter body (2) connected to the working environment ceiling through the hanger rods (2.1 ), the optical sensor (4) positioned on the sensor connection arm (3), the beam (5) transmitted from the optical sensor (4) to the Plansifter body (2) and the sensor response plate (6) parts and parts that ensure the projection of the beam (5) connected on the Plansifter body (2) and coming out of the optical sensor (4).

[0029] The Plansifter of the invention includes a plate connection arm (2.2) on the Plansifter body, which provides the connection of the sensor response plate (6) to the body (2), which allows the beam (5) coming out of the optical sensor (4) to be reflected on the Plansifter body in the optical motion control system.

[0030] The Plansifter optical motion control system of the invention includes a sensor connection arm (3) connected to the ceiling hanger body (1 ) independently of the body (2) so that the optical sensor (4) positioned on it is not affected by the movement of the Plansifter body (2).

[0031] The Plansifter optical motion control system of the invention comprises a sensor response plate (6) connected to the Plansifter body (2) by the plate connection arm (2.2) in correspondence with the beam (5) coming out of the optical sensor (4).

[0032] The Plansifter optical motion control system of the invention includes a sensor response plate (6) selected to have a surface area large enough to reflect the beam (5) coming out of the optical sensor (4) to the optical sensor (4) depending on the circular oscillation movement of the Plansifter body (2) in the horizontal plane under normal operating conditions of the Plansifter.

[0033] In the optical motion control system of the Plansifter of the invention, the beam (5) coming out of the optical sensor (4) during the operation of the Plansifter is reflected from the sensor response plate (2.2) and reaches the optical sensor (4) again, and in this way, it is determined that both the oscillating movement of the machine takes place in the desired way and the position of the body (2) is normal. In case of any excess that may occur in the oscillating movement of the body (2), the position of the sensor response plate (2.2) on the body (2) will be out of the standard area and the beam (5) will be reflected to a different position from the optical sensor (4). In this case, the optical sensor (4) will detect the position change of the body (2) and inform the operation and ensure that the plansifter is stopped urgently. Again, as a result of the movement of the Plansifter body (2) vertically as a result of the breakage or stripping that may occur from the hanger rods (2.1 ), the position of the sensor response plate (2.2) will be out of the standard area and the beam (5) will be reflected to a different position from the optical sensor (4). In this case, the optical sensor (4) will detect the position change of the body (2) and inform the operation and ensure an emergency stop of the plansifter.

[0034] Thanks to the optical motion control system of the Plansifter subject to the invention, the possibility of high maintenance-repair costs as a result of damage to the Plansifter due to irregular operation will be eliminated, and occupational accidents that may occur in the working environment will be prevented.
