detailed description

In order to clearly understand the technical solution of the present invention, its detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of the invention is not limited to specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, and there may be other implementations besides those described in detail.

In modern industry, intelligent electronic products are widely used, and the technology is relatively mature. The following embodiments are formed with reference to the metering function of the production process in the industrial automation production line operation, and the use of modern industrial multifunctional intelligent display instruments.

The system for displaying the pay-off speed and mileage in real time during the tension machine pay-off construction of this embodiment includes a rotary encoder and a multifunctional intelligent display instrument, and the tension machine is provided with a tension wheel;

The electronic component rotary encoder can be used to accurately measure the pay-off length. After collecting the electronic pulse signal, input it into a modern industrial multi-functional intelligent display instrument, and calculate the number of collected pulse signals and the corresponding collection time. It can display parameters such as tension machine construction pay-off speed and mileage.

The principle of using a rotary encoder is: the connecting shaft of the rotary encoder rotates a circle (360 degrees), and a fixed number of electrical pulses are output on the output line, and the angle of the connecting shaft is proportional to the number of pulses output on the output line. The connection shaft of the rotary encoder in this embodiment is connected to the tension wheel of the tension machine through a gear transmission, and the transmission ratio can be calculated to calculate the length of the wire stretched out from the tension wheel corresponding to each electric pulse. Connect the output signal of the rotary encoder to the input terminal of the multi-functional intelligent display instrument. Every time the instrument receives an electric pulse, it will perform an accumulation operation and display the operation result. The accumulated addend is the converted electric pulse corresponding to The length of the wire stretched out on the tension wheel, so the displayed result is the real-time wire length, that is, the mileage. Calculate the number of electrical pulses corresponding to unit speed per unit time, which is the speed coefficient, and set it in the multi-functional intelligent display instrument. Modern industrial electronic instruments have self-counting and timing functions. The instrument compares the number and speed of electric pulses received per unit time The coefficient can be converted in direct proportion to display the real-time pay-off speed.

In the model of the 90×2 intelligent development project, the equipment itself has a controller and a display. Using the existing resources of the equipment, there is no need to install a multifunctional intelligent display instrument. The output signal of the rotary encoder is connected to the controller. At the input end, after calculation and processing such as accumulation and proportional operation, the result can be output to the display for display.

The selection basis of the rotary encoder mainly includes: 1. The pulse type output on the output line when rotating; 2. The number of pulses output on the output line when rotating 360 degrees; 3. The rotary knitting size and installation method allowed by the equipment installation space; 4. Parameters such as working voltage, current, and power that are suitable for the equipment and display instruments; 5. The occasion and purpose of the equipment for spinning. The type and number of pulses output by rotary knitting should match the performance parameters of the multifunctional intelligent display instrument used with it, and the purpose should meet the requirements of long-term field operation and poor environmental conditions of the equipment.

The rotating part of the tension wheel cannot be equipped with a rotary encoder, the tension wheel shaft supports the bearing, the shaft head does not rotate, and the amount of rotation angle cannot be obtained, so the rotary encoder can only be installed on the shaft head of the reducer. The reducer meshes with the large gear of the tension wheel through the small gear, and the rotary encoder is connected to the tension wheel through a first-stage gear transmission. The pulse number of the rotary encoder can be converted into the pulse number corresponding to the rotation of the tension wheel by multiplying the ratio coefficient. Just can get the accumulative addend of multifunctional intelligent display instrument. The end face of the reducer has a large space, which is convenient for fixing and installing the rotary encoder as a bracket. When the tension machine has a large tonnage pay-off, the radial swing of the tension wheel gear caused by the deformation of the tension wheel shaft and the gap between the tension wheel bearings is relatively large, and the radial swing of the meshing reducer pinion is also large. Consider using COUP-LINK double-ring blue belt type flexible The coupling connects the gear end face of the reducer and the connecting shaft of the rotary encoder, which can overcome the force of the radial swing of the pinion of the reducer and protect the connecting shaft of the rotary encoder from being damaged.

After solving the above technical problems, the rotary encoder can be easily installed on the tension machine, as a tension machine pay-off speed and length counting device, to collect pulse signals, and provide them to electronic instruments to display the tension machine pay-off speed and length. The tension machine pay-off speed and mileage display system composed of rotary encoder and multi-functional intelligent display instrument has high display accuracy, good real-time performance, easy observation and easy installation.

The invention provides a system for real-time display of the pay-off speed and mileage during the pay-off construction of the tension machine. Compared with the mechanical counter, the electronic counting device has high counting precision and accurate display; It can calculate and display the working data of a variety of equipment, with powerful functions; the electronic counting device is equivalent to a displacement sensor, and the collected signals can be used by various instruments and control systems. The installation is simple and the cost is not high. Compared with mechanical counters, it has advantages obvious.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art can still implement the present invention Any modification or equivalent replacement that does not deviate from the spirit and scope of the present invention is within the protection scope of the pending claims.
