Description

1

The invention relates to mechanical engineering and can be used in assembly machines for oriented feeding of flat disk parts with a chamfer at one end.

The aim of the invention is to expand the technological capabilities of the vibrating hopper by ensuring the orientation of parts with a chamfer at one of the ends to the position of a chamfer down or chamfer up.

FIG. 1 shows the proposed vibrating hopper, a plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - section B-B in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 and 6 - orientation of the parts in the position of the bevel up; in fig. 7 and 8 - the same, in the face down position.

The vibrohopper contains a bowl 1, a screw feed tray 2, an orienting chute 3 coupled to it with side walls 4 and 5, and the wall 4 in its beginning in the direction of lifting the screw tray is joined to the screw feed tray 2 and then, turning smoothly and sparingly, turns into the vertical position, and the wall 5 in its beginning has a height smaller than the thickness of the oriented flat disk part, and its height increases to the size of the diameter of the oriented part, then both walls 4 and 5 smoothly rotate into opposite parts ones and at the level of the flat bottom 6 orienting chute 3 have longitudinal grooves 7 and 8 for receiving plates 9 and 10. The front ends of the plates are mounted for adjusting the distance between them and fixing them with screws positions 11 and 12 disposed in grooves 13 and 14 plates. The rear ends of the plates are hinged to the bottom 6.

Vibrating bunker works as follows.

Under the action of directional vibrations of the bowl 1 created by the vibrodrive, the parts bottom-up vibro-transport along the screw feed tray 2. At the entrance of the orienting chute 3, coming into contact with the beginning of the screw-shaped wall 4, the oriented parts are inclined to the center of the bowl 1, while the parts located in the top layer or in an upright position are dumped through the low part of the wall 5 to the bottom of the bowl 1 of the vibration hopper

The remaining parts, regardless of the location of their chamfer, continue to vibrate along the orienting chute 3, assuming a vertical position with the axis of rotation perpendicular to the direction of movement.

Getting into the zone where the angle between the walls 4 and 5 begins to increase, and the distance between the plates 9 and 10 is minimal, the detail with its sharp edge

It begins to abut plate 9 or 10, depending on the position in which it vibrates, and chamfer crawls onto the opposite plate 10 or 9, respectively.

Thus, the parts are forcibly tilted to the position of the chamfer upwards and further, gradually tilting, leaving the orientation zone only in the position of the chamfer upward.

In the case where the distance between the beginning of the plates 9 and 10 is maximum, the parts, resting against the flat bottom 6 of the orienting groove 3, due to the presence of the chamfer are inclined towards the latter. This is facilitated by the longitudinal grooves 7 and 8,

0 due to which the bottom width is slightly increased, and the part on the chamfer side in its lower part loses contact with the walls 4 and 5 of the orienting groove 3.

Being not limited by the plates 9 and 10 and the side walls 4 and 5 in the zone

5, increasing the angle between the latter, the part tilts toward the chamfer and then with a sharp edge crawls onto the plate 9 or 10 in an area where the distance between them is smaller, then reliably rests on one of the side inclined walls, and then leaves the orientation zone in the position face down.

Therefore, depending on the position of the plates 9 and 10 at the exit from the orientation zone, it is possible to obtain parts oriented to the position as chamfered

5 up and face down.
