[0002] PLANSIFTER HANGER ROPE SAFETY SYSTEM

[0003] TECHNICAL FIELD

[0004] The invention relates to a plansifter hanger rope safety system developed to automatically stop the operation of the machine by activating the machine in case of a load on the hanger rope, which provides the connection of the machine body to the ceiling in the working area of the machine body in the plansifters, in case of breakage of the plansifter hanger rods that provide the connection of the machine body to the ceiling in the working area or in case the machine body slides on the rods.

[0005] PRIOR ART

[0006] Plansifters used in mills are critical equipment that separates materials according to their size in order to ensure that ground grain and flour mixtures are of a certain fineness and quality standards. These machines sift the material by vibration using layers with different sifting diameters, allowing parts that meet certain size criteria to pass into the lower layers while keeping larger or unwanted parts on the surface. Thus, plansifters ensure that homogeneous and desired quality products are obtained, increase production efficiency and ensure that the final product complies with the standards.

[0007] In plansifters, sifter hanger rods (or hanger bars) are one of the critical components used to ensure the correct operation of the sifter. The main task of these rods is to carry and support the frame of the sifter frame or sifter. Sifter hanger rods allow the sifter to perform vibration movements properly, allowing for effective separation and sorting of materials.

[0008] The suspension 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 fragments can be separated. The suspension rods secure the sifter to the ceiling and prevent any imbalance 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 suspension ropes are used in addition to the hanger rods in order to prevent the plansifters from falling to the floor by separating from the ceiling in case of breakage of the sifter hanger rods in the sifter. The steel suspension 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 suspension 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 plansifters, 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 suspension 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 suspension rods break and the working order is disrupted.

[0011] In the current art, studies are carried out on different techniques for the control of the system in case of breakage of the hanger bars in the plansifters or disruption of the working order of the plansifter. In the document with file number CN117680356A, a control mechanism developed to excite the abnormal level aware system that may occur between the magnetic sensors placed in the horizontal plane opposite to the feeding plates on the plates to which the feeding inlets on a square plansifter are connected is mentioned.

[0012] In the plansifter described in the document with file number CN215964625 in the current technical literature, the hanger bars and steel rope to which the body is connected are mentioned. In the document, only the sensor is used for an irregular rotational speed on the mechanism that provides rotational movement in the machine, but no additional safety measures are mentioned due to the fall or slip of the plansifter on the hanger bars. A mechanical locking system developed for use in the connection of hanger bars in the plansifter in the document with file number CN204817167 in the current technical literature is mentioned. No additional safety measures are mentioned here due to the falling or slipping of the plansifter on the hanger bars.

[0013] BRIEF DESCRIPTION OF THE INVENTION

[0014] A hanger rope safety system for the plansifter subject to the invention has been developed in order to automatically stop the operation of the machine by becoming active in case of a load on the hanger rope that provides the connection of the machine body to the ceiling in the working area of the plansifter in case of breakage of the plansifter hanger rods that provide the connection of the machine body to the ceiling in the working area or in case the machine body slides on the rods, so that the machine is activated in case of a load on the hanger rope that provides the connection of the machine to the ceiling.

[0015] In the developed plansifter hanger rope safety system, the rope safety mechanism (3) is positioned on the plansifter hanger rope (2) so that the plansifter hanger rope (2) is between the fixed pulley (3.1 ) on the mechanism (3) and the movable pulley (3.2). During normal operation of the plansifter, the hanger rope (2) is positioned so that it is not tensioned between the fixed pulley (3.1 ) and the movable pulley (3.2). With the downward movement of the plansifter body (1 ) as a result of the breakage of the hanger rods and / or the sliding of the body (1 ) on the hanger ropes, the hanger rope (2) between the fixed pulley (3.1 ) and the movable pulley (3.2) becomes tense depending on the load on the hanger rope (2) and moves the movable pulley (3.2) towards the switch (3.5), enabling the switch (3.5) to be activated. In this way, the safety mechanism (3) is activated and the operation of the plansifter is stopped, and the possibility of high maintenance-repair costs as a result of damage to the plansifter due to irregular operation is eliminated, while occupational accidents that may occur in the working environment are prevented.

[0027] DETAILED DESCRIPTION OF THE INVENTION

[0028] The plansifter hanger rope safety system, which is the subject of the invention, is developed in order to automatically stop the operation of the machine by switching to the emergency state by becoming active 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 off or if the machine body slides on the rods, are loaded on the hanger rope (2), which provides the connection of the body (1 ) to the ceiling, in order to prevent the body (1 ) from falling uncontrollably to the ground in case of breakage of the hanger rods that provide the connection of the plansifter body to the ceiling and / or if the body slides on the hanger rods, and includes at least one fixed pulley (3.1 ), at least one movable pulley (3.2), at least one tension spring (3.4) to which the movable pulley (3.2) is connected in a way to control the passive position, at least one switch (3.5) to which the movable pulley (3.2) is connected via a center pin, and a rope safety mechanism (3) including at least one body plate (3.6) on which the pulleys (3.2) are connected on which the body (1 ) is connected to the ceiling.

[0029] The plansifter hanger rope safety system of the invention includes the hanger rope safety mechanism (3) connected on the hanger rope (2) so that the hanger rope (2) to which the plansifter body (1 ) is connected is between the fixed pulley (3.1 ) and the movable pulley (3.2).

[0030] The plansifter hanger rope safety system of the invention includes a hanger rope safety mechanism (3) in which the hanger rope (2) to which the plansifter body (1 ) is connected is positioned so that it is not tensioned between the fixed pulley (3.1 ) and the movable pulley (3.2) under normal operating conditions of the plansifter.

[0031] The plansifter hanger rope safety system of the invention includes a hanger rope safety mechanism (3) containing a movable pulley (3.2) that the hanger rope (2) moves from the fixed pulley (3.1 ) to the switch (3.5) with the effect of the load to be mounted on the hanger rope (2) during the downward movement of the plansifter for any reason.

[0032] The plansifter hanger rope safety system of the invention includes a hanger rope safety mechanism (3) containing a spring connection pin (3.3) that enables the connection of the tension spring (3.4) on the body plate (3.6) from the fixed end, which ensures that the movable pulley (3.2) remains close to the fixed pulley (3.1 ) when the safety system is in the passive position.

[0033] The plansifter hanger rope safety system of the invention comprises a hanger rope safety mechanism (3) comprising at least one tension spring (3.4), the fixed end of which is connected to the spring connection pin (3.3) on the body plate (3.6) and the movable end of which is connected to the movable pulley (3.2), preferably by means of a center pin.

[0034] The plansifter hanger rope safety system, which is the subject of the invention, includes a hanger rope safety mechanism (3) containing the switch (3.5) that the plansifter enables to be activated as a result of its connection, preferably through a center pin, depending on this movement of the movable pulley (3.2), where the hanger rope (2) comes to a tensioned position and moves away from the fixed pulley (3.1 ) with the effect of the load to be mounted on the hanger rope (2) during the downward movement of the plansifter for any reason.

[0035] In the plansifter hanger rope safety system of the invention, the hanger rope safety mechanism (3) positioned on the hanger rope (2) to which the plansifter body (1 ) is connected is positioned on the hanger rope (2) so that the movement of the hanger rope (2) is not tensioned between the fixed pulley (3.1 ) and the movable pulley (3.2) while there is no load on the hanger rope (2) under normal operating conditions of the plansifter. When the mechanism (3) is in the passive position, the movable pulley (3.2) stands close to the fixed pulley (3.1 ) depending on the force created by the tension spring (3.4). The sifter ensures that the load hanger rope (2) to be mounted on the hanger rope (2) becomes tense during the downward movement of the machine body (1 ) for any reason. In this case, the hanger rope (2) positioned between the fixed pulley (3.1 ) and the movable pulley (3.2) moves the moving pulley (3.2) away from the fixed pulley

[0036] (3.1 ). As a result of the movable pulley (3.2) moving away from the fixed pulley

[0037] (3.1 ), the pulley (3.2) preferably activates the switch (3.5) to which it is connected via a center pin. When the switch (3.5) is activated, the operation to which the plansifter is connected is warned and the machine is automatically stopped. Thus, while the possibility of high maintenance-repair costs as a result of damage to the plansifter due to irregular operation is eliminated, occupational accidents that may occur in the working environment are also prevented.
