1 TARIFF SAFETY STOP SYSTEM TECHNICAL FIELD The invention aims to improve operator safety in two-roller open dough machines. instantaneous detection of contact between the operator's chest or abdominal area and the bar 5 It relates to the safe stopping system that provides protection. PREVIOUS TECHNIQUE In two-roll open dough machines, operator safety is of critical importance. It has. In these types of machines, the operator has control over the mixing and kneading processes. Serious injuries can occur as a result of unintentional contact with the rollers. 10 Therefore, in accordance with the relevant occupational safety standards, the front of the machines If the operator's chest or abdominal area comes into contact with this part, the system will be activated urgently. Chest barrier (trip bar) systems that stop the chest are widely used. In conventional chest barrier systems, the barrier is usually placed at the front of the machine. It is associated with a single mechanically mounted safety switch. 15 This single switch activates the machine when the barrier bar (trip bar) is struck. It stops the barrier. The switch is usually via a mechanical cam connected to the barrier arm. is triggered. While these systems can provide the basic emergency stop function, they are not the only ones. It has a multi-channel security structure. There are problems encountered in these types of systems. One of these technical problems is a single 20 It is sensor-dependent. Monitoring the actual position of the barrier is only possible via a switch. Because of this, in case of switch failure, incorrect adjustment or mechanical jamming, the system There is a situation where the barrier's position cannot be accurately perceived. In this case... The machine continues to operate unsafely. Another problem is the misalignment issue. The trigger position of a single switch and 25 If the movement limits of the barrier bar are not adjusted correctly, the barrier may make slight contact. either fails to activate the emergency stop function or, conversely, malfunctions due to vibration. Undesirable situations arise, such as triggering events. 2 Another problem is the difficulty of adapting to machine dimensions. This applies to machines of different sizes. When the barrier height needs to be extended or shortened, the spring preload of single-switch systems or the trigger distance cannot be adjusted in a standard way; this reduces the safety level. It lowers it. In addition, in known systems, jamming occurs in the bidirectional movement of the barrier, and the spring pressure is 5. Due to imbalance or limited stroke, the trigger force is always constant. This situation does not affect trigger sensitivity, especially in large machines. This leads to differences. While current chest barrier systems provide a basic emergency stop function, they are not the only Technical shortcomings such as channel structure, adjustment difficulties and incompatibility with different machine sizes 10 Therefore, it cannot provide high security categories. This is especially true in industrial settings. fully compliant with safety standards in open dough machines operating on a large scale. This creates a significant gap in the reception. In conclusion, all the problems mentioned above necessitate innovation in the relevant field. has brought it to this state. 15 THE PURPOSE OF THE INVENTION The present invention aims to eliminate the aforementioned problems and provide technical solutions in the relevant field.

Bar DETAILED DESCRIPTION OF THE INVENTION 15 In this detailed description, the subject of the invention, the safe stopping system (A), is only the subject of the invention. with examples that will not create any limiting effects so that it can be understood better It is explained. The invention aims to improve operator safety in two-roller open dough machines. For the purpose of instantaneous contact of the operator’s chest or belly area with the bar (7) 20 It is related to the safety stop system (A) which enables its detection. For illustrative purposes, the movement of the horizontal axis in the + and – directions along the X-axis is shown. It describes that when the operator touches the bar (7), the bar (7) moves in the +X direction. as he approached the two-roller open dough machine, contact was made by the operator. by cutting the bar (7) - moving in the X direction, two roller open dough 25 It moves away from the machine and returns to its initial starting position. In other words, the bar (7) by moving from the starting position in the +X direction, a horizontal movement is achieved. the barrier approaches the open dough machine, then moves in the -X direction. It reaches its starting position. Figure 1 shows the appearance of the safety stop mechanism. Safety movable element that interacts with the operator's possible contact in the stopping mechanism bar. The bar mentioned (7) is one of the two roller open dough machines mentioned. open dough machine at a distance that will prevent the operator from touching the machine is positioned. The operator contacts the bar (7) with his chest or abdominal area. When this happens, the bar (7) can move along its own axis in the +X and –X directions. It is structured in this way. This movement triggers the safety stop system (A). It constitutes the necessary mechanical input. 10 As shown in Figures 2, 3 and 4, the primary safety switch (1) is in normal operation. In this case, it is in the open position and the operator touches the busbar (7) When activated, it shuts down upon transmission of motion, sending an emergency stop signal. Primary safety switch (1), push movement of bar (7) (distance of advancement in -X and -X directions) 15 that will correspond to the precise trigger point, directly proportional to the distance. It is positioned in this way. The secondary safety switch (2) is in the closed position during normal operation and is attached to the busbar (7) It activates upon contact, transmitting motion and sending an emergency stop signal. Thus, in the system, the second safety switch (2) is in the opposite direction to the primary switch (1) A signal change occurs. These two switches (1,2) have a simultaneous but opposite situational 20 This change both increases the system's triggering reliability and allows for fault detection. In other words, the primary safety switch (1) is opened by contact with the busbar (7). from closed position to open position, secondary switch (2) from closed position to open position The system's reliability is ensured by the continuous activation of a safety switch in the system upon its passage. is provided. 25 The basic principle that enables the bar (7) to move in the +X and –X directions in a controlled manner. The element is a spring. The bar (7) is positioned between two springs (3). The operator's When the bar (7) moves upon contact, this movement is via the spring (3) both primary (1) and the secondary (2) safety switches are mechanically transmitted to each other. Thus, both switches (1,2) are triggered in the corresponding manner within the same time period. When contact is broken, the spring 30 (7) returns the busbar (7) to its original position. In this way, the system returns the busbar to its original position after each trigger. It automatically returns to its starting position. 6 Bushing (4) adjusts the preload and trigger position of the spring (3) according to different machine dimensions. It is the element that allows for adjustment. Two-roller open dough machines are different. Since it is produced in widths, the length of the bar (7) also changes by extending it. For example The length of the bar (7) in the 26'' Two roller open dough machine is 18'' Two roller The length of the bar (7) in the open dough machine and the breast bar for 12'' is 5 Considering its length, different pressure forces are required. Two rollers. As the size of the open dough machine increases, the length of the bar (7) also increases. In other words, the dimensions of the two-roller open dough machine and the length of the bar (7) There is a direct proportionality between them. In this case, in order to keep the spring (3) pressure at a standard level, the bushing (4) must be 10 The preload and trigger position are adjusted. By increasing the length of the bar (7), the spring (3) To adjust the pressure force it will apply, move the bushing (4) in the +X direction. This is ensured. The pressure that the spring (3) will apply as the length of the bar (7) decreases. In order to reduce its force, the zodiac sign is moved in the (4) –X direction. The mentioned zodiac sign Thanks to its movement in the +X and –X directions, the spring (3) 15 is suitable for bars (7) of different lengths. The pressure force is adjusted. The adjustment screw (5) allows the bushing (4) to move and be fixed in the +X and –X directions. It provides. If the length of the bar (7) is increased, the adjustment screw (5) +X The bushing is moved in the +X direction by applying a strong compression force in that direction. By ensuring this, it is also secured. By reducing the length of the bar (7) 20 The adjustment screw is loosened in the -X direction, allowing the bushing to move in the -X direction as well. The bushing (4) moving in the X direction is fixed by the adjustment screw (5). The mentioned adjustment Thanks to the fixing of the screw (5) bushing (4) during operation, vibration, impact or This prevents loosening due to prolonged use. After the bushing (4) is adjusted Then, by tightening the adjustment screw (5), the bushing (4) is fixed on the spring (3). In this way, the trigger is 25 The force remains constant and the system is protected against unauthorized tampering except for maintenance or adjustment. It will be protected. Primary safety switch (1), secondary safety switch (2), spring (3), bushing (4) and adjustment screw Elements such as (5) are placed inside the protective housing (6). The protective housing (6), These elements are exposed to environmental factors such as dust, humidity, steam, and chemical splashes in the production environment. protection against impacts and mechanical shocks that may come from operator equipment It also ensures that the system's sensitive trigger points remain stable for extended periods. 7 It helps to keep it in place. If necessary, a removable guard can be placed on the body (6). The lid is also integrated. If the operator's chest or navel area comes into contact with the bar (7), the bar (7) It moves along its own axis in the +X or –X direction. This movement is via the spring (3). It is transferred to both the primary (1) and secondary (2) safety switches. The primary safety switch is 5 (1) transmission signal to the emergency stop circuit by switching from open to closed position sends. The secondary safety switch (2) stops by switching from the closed position to the open position. It sends a signal. These two signals simultaneously stop the machine. Contact is broken. When lifted, the spring (3) returns the bar (7) to its initial position; the switches (1,2) also return to the starting position. (primary safety switch (1) in the open position, secondary safety switch (2) in the closed position 10 (it returns to its position). The system is thus ready to be triggered again. The scope of protection for the invention is specified in the claims, and this is absolutely concise and detailed. The explanation cannot be limited to what is given for illustrative purposes. A technically expert person... the person, without deviating from the main theme of the invention, in light of what has been described above, similar It is clear that this can lead to the emergence of new structures. 15
