The vibratory hopper feeder consists of a screw tray 1, a hopper 2 for loaded parts, connected by inclined rod springs 3 with a reactive plate 4. An electromagnetic vibration exciter 5 is placed between the reactive plate 4 and the hopper 2, the measles 6 of which are twisted oscillations, i.e. . elliptical vibrations are realized. By varying the voltage applied to the windings of electromagnetic vibration exciters and the phase angle between voltages, the oscillation path of tray 1 can be changed by adjusting the transport modes that are optimal for various classes of parts, as well as carry out the reverse transport at less than 10 meters. right tray 1 left. The parts are loaded into the hopper 2 to a level exceeding the level of the lead-in part of the tray 1. At the same time, the spring 15 is deformed by the weight of the parts and the bottom 18 moves in the hopper 2 downwards. With the help of dogs 19 bottom 18 under the action of vibration of the hopper 2 is brought into rotational motion. The parts under the action of the rotating bottom 18, as well as interacting with the vibrating side surface are mounted on the bunker 2. By the additional 20 bunker 2, the electromagnetic vibration exciter 7 rotates around the axial movement around the bunker 2

also placed between the reactive plate 4 and are fed to tray 1, moving along

and the bunker 2 and its measles 8 is fixed to the orienting device and

through the screw tray 1. on the way out of the vibrating feeder into the oriented screw tray 1 with the orientated orientation. As it is received, a device (not shown) is connected to no parts on tray 1 under the action of

the hopper 2 by means of annular springs 15 to the rod 16 bottom 18 under 35

10 with the possibility of vertical displacement relative to each other.

The entire structure through the vibration insulators 11 rests on a fixed base 12. On the base 12 a hollow post is fixed

I 13 with a guide bushing 14, through which the spring 16, which rests on the spring 15, passes 16, the upper end of which has a bottom 18 in the support assembly 17. On the periphery of the bottom 18 there are several elastic dogs 19 resting against the surface of the bunker 2 ( Fig. 2). When the hopper 2 is loaded, the bottom 18 is in its extreme upper position at

Level I of the lead-in part of the screw tray 1.

; The spring 15 provides the stroke of the rod 16 to 40 within the movement of the bottom 18 from the lower part of the hopper 2 to the extreme upper position.

Vibrating hopper feeder works as follows.

It maintains the level of detail above the lead-in part of tray 1. The vibrating feeder is changed from one product size to another by replacing the screw tray 1 with the orienting device, in particular replacing the right screw tray with the left one with the reverse of the speed of vibrotransport.

Tray 1 contains a small number of parts. The bulk of the parts is in the hopper 2, which is not rigidly connected to the screw tray 1, and rests on a rotating bottom 18, which, and in turn, rests on a fixed base 12 through the spring 15. Therefore, the mass of the load does not significantly affect the working oscillation body, which makes them quite stable in the process of working vibropitel. Adjusting the elliptical oscillation paths of the screw tray allows the power supply to be tuned to the windings of the electromagnetic shaker for optimal operating conditions for alarm 5 and 7 and pulsating most different parts are fed. Rebalancing vibration with phase shift between them. Under the action of the disturbing force of the electromagnetic vibration exciter through a new size-oriented product is associated with the replacement of the screw tray 1 with a relatively small size of the inclined springs 3 are implemented VNE- ,,. This makes it possible to reduce the stability of the tovary oscillations of the bunker 2. Due to the performance of the vibropitel.
