Project description
Offering remote work. Trebetncz programming PLCs for stepper motors GX Works2. Due to the instability of the Chinese equipment, it is desirable to replace their system with a modern element base. PLC/ in agreement with the contractor. 2 standard Chinese stepper engine feed film. 1 inverter determining the number of cuts. Controlled by stop start signals. In principle, for people in the topic 1-2 days. Maybe someone's done this before.
Further in detail
(1) the machine is divided into 2 parts to reduce the resistance to movement of the film. Both parts are controlled by stepping motors. Similar.
Engine 1 at the entrance and engine 2 at the exit. In normal condition, the speed of the engine 1 is 0.5% less than the speed of the engine 2 (the speed difference is set in the machine settings).
(2) They are separated by a dancing shaft. The shaft that's on the tapes. Its lifting film means that the film tension is high (the sensor is at the bottom or not) and it is necessary to increase the speed of the first engine, so that it would become higher than the second (the speed difference is set in the machine settings). As a result, the tension will fall and again it is necessary to return to the original situation where the speeds change places.
There is also a photo tag sensor. Working on the following algorithm. He can't see. There is a procedure to help him see - slowing down the speed and determining the presence of a label at a speed below (the speed difference is set in the machine settings). Naturally, everything is controlled through a standard HMI panel.
Adjusting temperature zones through a signal from thermocontrollers. There is a temperature, there is no temperature. The movement of the conveyor when dialing a given amount in a pack of a given number of seconds. Support mechanisms for work. Type when stopping substitute special fixtures to stop the car at the top point and therefore at the start they are removed at the beginning. In the absence of a label on the package and the absence of it on the second package, stop also (the number of packets is set). The speed adjustment is determined by setting the voltage. Invertor. And synchronizing the speed of stepping motors. The ability to work without a label, for a given length. (step stepping motor). The movement of stepper motors is not constant, but variable. This is a physical process and is inertia. Therefore, at the start, the speed is less and it increases. When approaching the length of the package, it slows down. If there is a label, it slows down for a given number of mm. Programmable on GX Works2 GKR and China panel. 24 digital input and output ) (total 48). Only those who have programmed the control of stepper motors are interested.
To facilitate the work and payment (settings), respectively, the program itself and the possibility of making changes to it are needed. This makes the job of the contractor much easier and increases my guarantee.
