Description

Technical field:

[0001] The utility model belongs to the technical field of tire manufacturing, and particularly relates to a tire wire ring winding broken wire and material broken detection and alarm device. Background technology:

[0002] In the radial tire wire ring winding production line, wire breakage and material tray breakage often occur during the winding process. During the production process, the wire storage ring guide wheel and the wire guide tray device are in high-speed operation, with high speed and large inertia. Once wire breakage and material breakage occur, if the on-site operator fails to stop the wire pulling in time, the wires on the storage ring wire wheel will all fall apart. In serious cases, the wires will be directly deformed or damaged, resulting in a decrease in quality and labor efficiency. Since the original equipment manufacturer's alarm device was designed unreasonably and has defects, it often malfunctions or does not function, and cannot play a protective role, causing a lot of trouble to production and a large amount of material scrap.

[0003] Based on the above reasons, designing auxiliary detection measures to make up for the deficiencies and defects in equipment functions and improve the functions of production equipment has become the object of research of this utility model. Summary of the invention:

[0004] The utility model aims to design a tire wire ring winding wire and material breakage detection and alarm device which can judge the wire winding state by detecting the wire running speed.

[0005] The technical solution of the utility model is achieved as follows: a tire wire ring winding broken wire and material detection and alarm device, characterized in that it includes a PLC module, a meter module, a limit switch and an alarm module; the meter module and the limit switch are connected to the input end of the PLC module, and the alarm module is connected to the output end of the PLC module; the PLC module is provided with a counting display screen and a reset button; the meter module includes a meter and a wire wheel linked with the meter wheel, the running wire is wound around the wire wheel, and drives the meter to count, which is displayed on the counting display screen of the PLC module in due time; a proximity switch is also arranged on the side of the meter wheel, and a metal block is arranged at each of the three equal angles of the meter wheel surface, and the proximity switch signal is connected to the input end of the PLC module; the limit switch is a touch limit switch, and is arranged at the edge of the wire transition turntable, and the contact arm of the limit switch is perpendicular to the transition turntable; the alarm module includes sound and flash.

[0006] The wire wheel of the metering module is a flat groove wheel made of nylon, the width of the flat groove is 5mm to 10mm, the circumferential radius of the flat groove is 955mm, and the flat groove of the wire wheel is placed on the running steel wire.

[0007] The contact arm in the limit switch is a column spring, one end of which is fixed on the limit switch, and the suspended end of the column spring is located at the edge of the turning point of the steel wire of the transition turntable.

[0008] The utility model has the characteristics of unique conception, easy installation and accurate detection. In addition to satisfying the length measuring function in the wire winding process, it can also detect the walking speed of the wire, judge the fault by the speed change, and then use the limit switch to judge the broken wire and material.

[0020] Reference Figure 1 and Figure 2 The tire wire ring winding wire breakage and material breakage detection and alarm device comprises a PLC module 1, a metering module 2, a limit switch 3 and an alarm module 4; wherein the metering module 2 and the limit switch 3 are connected to the input end of the PLC module 1, and the alarm module 4 is connected to the output end of the PLC module. Through PLC program programming, the collected signals are processed to determine the wire breakage of the wire ring winding, the material breakage protection function and the monitoring of the steel wire material situation.

[0021] The PLC module 1 is provided with a counting display screen and a reset button. The counting display screen also has an input keyboard, which provides the setting and modification of parameters such as the number of meters, which is also a common practice in industrial design. The setting of the reset button provides convenience for the test operation and can also be used as the initial reset of each tire wire ring winding.

[0022] The meter module 2 includes a meter 21 and a wire wheel 23 linked to the meter wheel 22. The running wire 5 passes around the wire wheel 23 and drives the meter 21 to count, which is displayed on the counting display screen of the PLC module in due time. For this reason, the circumference design of the wire wheel 23 is associated with the meter. The wire wheel 23 is a flat groove wheel made of nylon. The width of the flat groove is 5mm to 10mm, and the circumferential radius of the flat groove is 955mm. With the help of the flat groove of the wire wheel 23, it is placed on the running wire to maintain a stable placement without slipping out. The reasonable diameter design simplifies the length conversion of the meter 21.

[0023] The meter counter 21 is a standard part, and a proximity switch 6 is also provided on the side of the meter wheel 22. A metal block 61 is provided at each of the three equal angles on the surface of the meter wheel 22. The signal of the proximity switch 6 is connected to the input end of the PLC module 1. That is to say, every time the meter wheel 22 rotates one circle, three trigger pulse signals are generated. By comparing the speed of the pulse signal, the running state of the steel wire 5 can be judged.

[0024] The meter counting module 2 is arranged between the steel wire preheating section and the steel wire storage rack, and measures the length of the steel wire and alarms for wire breakage, and triggers wire breakage protection.

[0025] The limit switch 3 is a touch-type limit switch and is arranged at the edge of the steel wire transition turntable 7. The contact arm 31 of the limit switch is perpendicular to the transition turntable 7. More specifically, the contact arm 31 in the limit switch is a column spring, one end of which is fixed on the limit switch 3, and the suspended end of the column spring is at the edge of the steel wire bend of the transition turntable 7. Once the wire is broken or the wire material is used up, the loose steel wire 5 will break free from the transition turntable and quickly pop out, touching the contact arm 31 of the limit switch, giving a trigger signal to the PLC module 1, driving the alarm module 4 to alarm and stop traction, realizing the protection of the production status and notifying the on-site technicians to troubleshoot.

[0026] The limit switch 3 is arranged between the steel wire preheating section and the steel wire lead-out section, and alarms the steel wire breakage or material breakage and triggers the protection. It is generally arranged at the edge of the third transition turntable 7 of the lead-out device.

[0027] The alarm module 4 includes sound and flashing lights, which notify on-site technicians.

[0028] The design procedure is as follows:

[0029] 1) When the traction is in normal operation, the wire breaks in the middle of the wire preheating section and the wire storage rack. The loose wire causes the wire wheel on the meter counter to stop rotating. At this time, the proximity switch does not sense or always senses the signal of the metal block installed on the other side of the meter counter and the meter wheel within 2 seconds, indicating that the wire wheel on the meter counter does not rotate. At this time, the PLC module immediately determines that it is a wire breakage fault according to the program, outputs an alarm signal, and triggers the protection at the same time. The traction drum automatically stops traction and suspends winding.

[0030] 2) When the material on the wire coil disc is close to the last few wires left, or the wire is broken from the wire preheating section to the wire unwinding, the wire is loosened and instantly straightened due to the rotation inertia of the disc and the bending elastic force of the wire, and touches the touch limit switch installed on the edge of the third transition wheel of the unwinding. At this time, the program in the PLC module immediately determines that the wire is broken or the material is broken, and an alarm will be sounded and flashed, and the protection will be triggered to automatically stop traction and pause winding.

[0031] 3) The installed meter counter and quick counting display are mainly used to calculate the number of meters of the guided wire. If the count value displayed on the counting display is equal to the preset total number of meters of wire, the program will immediately determine that the wire material is running out. At this time, it will also output an alarm to warn of the production status and automatically stop traction, thus playing a dual monitoring and protection function.

[0032] Through the above specific measures, production labor efficiency can be effectively improved, material scrap can be reduced, and product quality can be improved; the insufficient functions of the original machine equipment can be compensated to make the machine more automated; and it can make it easier for operators to master the use of steel wire on site.
