[0002] ELECTRIC CURRENT SAFETY SYSTEM IN PLANSIFTER HANGER ROPE

[0003] TECHNICAL FIELD

[0004] The invention relates to the electric current safety system in the plansifter hanger rope 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 plansifter, or in case the machine body slides on the rods, in case of a load on the hanger rope that provides the connection of the machine to the ceiling in such a way that a load is placed on it.

[0005] PRIOR ART

[0006] Plansifters used in mills are critical equipment that separate 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 hanger rods contribute to the stable and stable operation of the sifter. The balance of the sifter is critical so that the materials can pass through the sifter correctly and unwanted parts can be separated. The hanger 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] In plansifters, steel hanger ropes are used in addition to the hanger rods in order to prevent the plansifter from falling to the ground by separating from the ceiling in case of breakage of the sifter hanger rods. During the normal operation of the plansifter, the steel hanger ropes, which are connected without tension so that there is no load on them, prevent or slow down the plansifter from falling to the ground by meeting the load in case the hanger rods break for any reason or the plansifter slides down on the rods.

[0010] Although the downward load can be met by the steel hanger ropes in case of breakage of the hanger rods that provide the connection of the body to the ceiling in the plansifters, the plansifter can continue to operate. Due to the high circular motion in the plansifter, both the excessive damage of the machine and the high risk of accidents in the working environment may occur in this way. For this reason, it is of great importance to stop the operation of the plansifter immediately in case of breakage of the hanger rods and deterioration of the working order.

[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 plansifter are connected is mentioned.

[0012] In the present technique, studies are carried out on different techniques for the control of the system in case of breakage of the hanger rods in the plansifters or disruption of the working order of the plansifter. In the document with file number CN117680356A, a control mechanism developed to warn the system of an abnormal level difference that may occur between the magnetic sensors placed in opposite horizontal planes on the plates to which the feed inlets on a plansifter are connected and the feed plates is mentioned. In the sieving machine described in the document CN215964625 file number in the available technical literature, the hanger rods and steel rope to which the body is attached are mentioned. In the document, only a sensor for an irregular rotational speed is used on the mechanism that provides rotational movement in the machine, but no additional safety precautions are mentioned due to the plansifter falling or slipping on the hanger rods.

[0013] 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.

[0014] BRIEF DESCRIPTION OF THE INVENTION

[0015] An electric current safety system has been developed on the hanger rope of the inventive plansifter in order to automatically stop the operation of the machine in case of breakage of the hanger rods of the plansifter, which provide the connection of the machine body to the ceiling in the working area of the plansifter, or in case the machine body slides on the rods, in case of load on the hanger rope that provides the connection of the machine to the ceiling.

[0016] In the electric current safety system in the developed plansifter hanger rope, a conductive wire (5) is used on the hanger rope (3), which provides the safety connection of the plansifter body (1 ) to the working environment ceiling, which is connected in such a way that electric current passes through it. The hanger rope (3) has a curved structure in the vertical direction by means of rope guides (4) positioned on any point selected to match the placement of the plansifter body (1 ). The conductive wire (5) connected on the hanger rope (3) against the curved structure formed by the hanger rope (3) at the point where the rope guide (4) is used is positioned in a straight direction along the rope connection so as not to form any curvature. Thus, the length of the conductor wire (5) is shorter than the length of the hanger rope (3). Thanks to the length difference between the hanger rope (3) and the conductor wire (5), the force that will act on the hanger rope (3) in the event that the hanger rods (2) break or the plansifter body (1 ) slides on the ropes (2) will break the conductor wire (5) and cut the current passing through the wire (5). In the event that the current passing through the conductive wire (5) is interrupted, 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.

[0025] DETAILED DESCRIPTION OF THE INVENTION

[0026] The electric current safety system in the plansifter hanger rope of the invention, which is developed to automatically stop the operation of the machine in the event that the plansifter hanger ropes, which provide the connection of the machine body to the ceiling in the working area of the plansifters, break off or the plansifter hanger ropes, which provide the connection of the machine body to the ceiling in the event that the machine body slides on the rods, are loaded on the sifter rope that provides the connection of the machine to the ceiling in such a way that the machine is loaded on the ropes, includes at least one conductive wire (5) parts and sections positioned at any point selected to comply with the placement of the plansifter body (1 ) on the hanger rope (3), which allows the plansifter body (1 ) to connect to the working environment ceiling, and / or to prevent the body (1 ) from falling uncontrollably towards the ground in case of sliding on the hanger rods (2). The electric current safety system in the plansifter hanger rope of the invention comprises two rope guides (4), which are preferably positioned at any point on the hanger rope (3) to match the placement of the plansifter body (1 ) and enable the hanger rope (3) to have a curved structure in the vertical direction.

[0027] The electric current safety system in the plansifter hanger rope subject to the invention includes a conductive wire (5) connected in a straight direction so as not to form any curve on the hanger rope (3) against the curved structure formed by the hanger rope (3) at the point where the rope guide (4) is used.

[0028] The electric current safety system in the plansifter hanger rope of the invention includes a conductive wire (5) connected to the hanger rope (3) in such a way that electric current passes through it and the length of use is shorter than the length of use of the hanger rope (3).

[0029] The hanger rope (3), which provides the safety connection of the plansifter body (1 ) to the working environment ceiling in the electric current safety system in the plansifter hanger rope of the invention, has a curved structure in the vertical direction by means of the rope guides (4) positioned on any point selected to match the placement of the plansifter body (1 ). The conductive wire (5) connected on the hanger rope (3) against the curved structure formed by the hanger rope (3) at the point where the rope guide (4) is used is positioned in a straight direction along the rope connection so as not to form any curvature. Thus, the length of the conductor wire (5) is shorter than the length of the hanger rope (3). Thanks to the length difference between the hanger rope (3) and the conductor wire (5), the force that will act on the hanger rope (3) in the event that the hanger rods (2) break or the plansifter body (1 ) slides on the ropes (2) will break the conductor wire (5) and cut the current passing through the wire (5). With the interruption of the current passing through the conductive wire (5), the safety system of the invention is activated and the operation of the plansifter is 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.
