Description

one

The invention relates to mechanical engineering and can be used to orient and feed long-length, easily-adherent parts.

The purpose of the invention is to increase the reliability of the vibrating hopper when feeding long, easily-assembled parts. (By eliminating the formation of jams At the entrance of the feeder.

On. FIG. 1 shows a general vibrating bunker; in fig. 2 - the bottom of the vibrating hopper, top view; in fig. 3 is a view A of FIG. 2; in fig. 4 - orientable part.

The vibratory bunker contains a narrow shell 1 with a screw feed chute 2 and a bottom. One half of the bottom of the vibrating hopper is made in the form of a plane 3 with a conical protrusion 4 located along the axis of the shell 1, and the other in the form of a half truncated cone 5 with a notch 6, which has a sickle shape in the plan, turned with a tip in the direction of lifting the screw feed tray 2. The notch 6 is bounded by two intersecting surfaces: an inclined plane 7 adjacent in radius to the bottom half of the bottom, and a curvilinear surface 8 adjoining the lateral surface of the conical protrusion 4. The entry section 9 of the screw feed tray 2 races olozhen diametrically opposite the joint 10, the flat surface 7 of the recess 6 with the plane of the bottom 3 vibrobunkera and interfaced with its conical surface. A hole 11 is made in the center of the bottom of the vibrating hopper for mounting it on the vibrodrive (not shown). The entry portion 9 of the screw feeder tray 2 is made along a width greater than the length of the feed piece 12.

Vibrating bunker works as follows.

Details 12 loaded into the vibrator

the core in bulk, under the action of directional oscillations excited by the vibrodrive, begin to move along its

zhuts on circular trajectories m, evenly distributed along it, and set--; blunt from it on an inclined plane 7 notches. 6. On an inclined plane 7, the parts move along the paths defined by the crescent-shaped notch 6. Due to this, the parts gradually separate as they move along the length of the notch from their total mass in the notch, and from the plane 7 go to conical bottom surface, evenly distributed over it. As a result, the formation of part jams is eliminated at the lead-in portion of the screw feeder. The extended lead-in section 9 of the screw tray ensures the maximum possible reception of parts from the conical part of the bottom. As the screw tray moves, excess parts due to its gradual contraction are dropped onto the flat part of the bottom of the vibrabox.

rmula of invention

A vibratory bunker containing a cylindrical shell with a screw tray and a bottom characterized in that, in order to increase reliability when supplying easily-mounted parts, one half of its bottom is made in a plane with a conical protrusion located along the axis of the shell, and the other in the form of a half truncated a cone with a notch, which has in its plan the shape of a sickle, which is pointed in the direction of the lifting of the screw tray, and is bounded by two intersections

surfaces — an inclined plane adjoining its flat half along the bottom radius and a curvilinear surface adjoining the lateral surface of the aforementioned conical protrusion, while the lead-in path of the screw tray is diametrically opposite to the flat surface junction of the above-mentioned notch with the bottom plane and matching horses

the bottom. On the flat part of the bottom of the part, the moving bottom surface.
