Arrival at the lead-in parts of the trays 2. The parts that arrived at the trays 2, under the action of active oscillations of the bowl 1, are transported along them to the delivery. As the feeder operates, due to a decrease in the mass of the parts in it, the spring 15, decompresses, raises the rotary bottom, ensuring a constant level of parts. The use to bring the rotational vibrations of the plate 7 into rotation ensures the stability of the amplitude of the active oscillations of the bowl 1. 1 Il.

The drawing shows the feeder, a general view.

The vibratory hopper feeder contains a bowl 1 with screw trays 2.j mounted on a cylindrical pre-bin 3, which is mounted on the upper flange A of the lattice hyperboloid torsion 5, the pinnacle flange 6 is torsio1 and 5 mounted on a jet plate 7 mounted on shock absorbers B on the base 9 An electromagnet 10 is mounted on the reactive plate 7, and its measles 11 is fixed on the flange 4 of the torsion 5. Based on

9, a hollow post 12 is fixed with guide bushings 13 installed therein. A stem 14 is inserted into the holes of the bushings 13, resting its lower end on the spring 15. At the upper end of the stem 14, a rotatable bottom 17 is mounted on the bearing support 16 evenly arranged elastic dogs 18. On the reactive plate 7, the supports 19 are fixed, the upper ends of which are freely inserted into the cavity of the pre-bunker 3 through you

through holes 20, filled in the upper flange 4 of the torsion 5; at the upper ends of the uprights 19, a disk 21 with a shell 22. secured thereto is fixed. The shell 22 is located inside the pre-bin 3 between its wall and the rotary bottom 17 with the ability to interact with elastic dogs 1B of the latter.

Vibrating hopper feeder works as follows.

The parts are loaded into the prebunker 3 and the bowl 1 to a level slightly exceeding the level of the lead-in part of the screw of the trays 2. In this case, the rotary bottom 17 with the stem 14 under the action of the weight of the parts is lowered, the springs are spring 15.

When the electromagnet 10 is turned on, its measles 11 are periodically attracted to it with the frequency of the supply voltage. As a result, oscillations of the lattice hyperbolic torsion 5 and, accordingly, oscillations of pre-hopper 3 with bowl 1 mounted on its upper flange 4 are excited. At the same time, the plate 7 reacts on the shock absorbers 8, which are transmitted to the rim 22 through the racks 19 and the disk 21. The vibrating shell 22, interacting with resilient dogs 18, mounted around the periphery of the bottom 17. causes it to rotate together with the whole mass of parts on it. As a result, uniform filling of the lead-in parts of all screw trays 2 is ensured. Parts that fall on the lead-in parts of the screw trays 2, under the action of inertial forces arising from active oscillations of the bowl 1, are transported along the screw trays from bottom to top and go to the top. As far as the feeder works, i.e. with a decrease in the mass of the parts located in the pre-cylinder 3, the spring 15 opens and raises the pivoting plate 17. Due to the appropriate choice of the spring stiffness 15, the free surface of the parts remains unchanged during the entire device operation time. The use of reactive oscillations of the plate 7 for driving the bottom 17 of rotation ensures the stability of the amplitude of active oscillations of the bowl 1, which significantly increases the speed of vibro-transport of parts along the screw chutes 2 and, accordingly, increases the performance of the feeder.
