Increase the functionality of vibration feeders with electromagnetic vibration
Under modern conditions vibrating hopper feeders with electromagnetic drive are irreplaceable when it comes to production processes in mechanical engineering and instrument making optimization processes. They are used to download small, medium or miniature details to automated technological equipment, such as automatic machines, automatic lines and automated complexes, or any other flexible automated production. The vibrating hopper loading devices are most commonly used in transportation and loading of details on working positions of assembly automatic machines and assembly automated complexes. In this case the details must be issued in a clearly oriented state. For this purpose, the stationary automated orienting devices, or the orienting devices located directly on the working vibrating feeders` bodies are used. Low compressed air pressure is often used in these devices. Apart from this, in some cases the low compressed air pressure is used in vibrating feeders to increase the maximum lifting angle when vibrating transportation of details on a transport tray of the feeder. We already know the designs of vibrating feeders, whose transport tray is equipped with channels and openings for the supply of compressed air, whose jets affect the parts that are transported in order to increase the maximum possible lifting angle or the speed of parts transportation, as well as to ensure the guaranteed gap between them at the download position. We also know the vibrating feeders` constructions equipped with jet pneumatic devices, which are set exactly on the vibrating feeder hopper and serve for non-contact orientation of details that are issued. All of these devices use the low compressed air supplied by means of the flexible pipeline from a workshop pneumatic network. But the fact that such network is simply absent in many enterprises` workshops makes it impossible to use the vibrating feeders like these, this way decreasing their use. For expanding their use it is necessary to have vibrating feeders with individual low pressure compressed air source. Modern production manufactures new models of machines with high technical economic indicators, so functionality increase of the existing one equipment and the development of new schemes of machines is an important task for designers and technological equipment manufacturers, because minimal improvement of its technological and performance can lead to a significant economic effect. The set of elements affecting the performance and efficiency of vibrating bunker feeders with electromagnetic drives that have a directional elastic system are presented in this paper. The additional structural elements increasing the functionality of such feeders are offered.
