Description

The invention relates to mechanical engineering and can be used to load machine tools with needle roller type parts.

A boot device is known, which contains a bunker, a working disc and a discharge tray with a visor for resetting incorrectly oriented parts.

It is also known to have a loading device comprising a hopper, a work disk and a discharge tray with lower and upper bars and with a receiving straight line section equal to the double length of the fed part 2j.

However, these devices are unreliable in operation due to possible jamming of the parts in the receiving part of the detachable tray.

The purpose of the invention is to increase the reliability of operation of friction bunker devices.

This goal is achieved. Thus, the receiving end of the lower plank of the discharge tray is made in the form of a triangular pyramid with an inclined side that spirals into a radial surface with a progressively increasing chamfer.

In this case, the receiving end of the upper rail of the discharge tray is located behind the sharp end of the triangular pyramid of the lower rail, and the latter’s radius surface is eccentric relative to the axis of rotation of the working disk.

FIG. 1 shows the device, a general view; in fig. 2 - reception

0 part of the discharge tray; Fig. 3 discharge tray, section.

The device contains a hopper 1 reinforced with steel tape 2, a rectangular discharge lotto. 3 formed by the lower 4 and upper 5 bars, the working disk 6 with a friction surface 7. The receiving end of the lower bar 4 is made pointed in the form of a triangular pyramid 8 s the inclined side 9 / spiraling into the radial surface, 10, equipped with a progressively increasing chamfer 11. The receiving end of the upper plank 5 has a bevel 12 placed behind the sharp end of the triangular pyramid 8 of the lower plank 4, the value of the diameter details. Work disk 6 is fixed on

shaft 13 and installed in bearings 14.

The device works as follows.

Parts 15, loaded in bulk into the hopper 1, by the inertia of the rotating working disk 6 are thrown to its periphery and directed towards the discharge tray 3, where they meet with the receiving ends of the upper 4 and lower 5 arms. If the part 15 approaches the discharge tray 3 in a vertical or inclined position, then it is pushed away from its entrance by a bevel 12, and if it is horizontal and perpendicular to the wall of the bunker 1, it is thrown off from it by the pointed end of a triangular pyramid 8 with an inclined side

9, and then - a radial surface

10, while changing the trajectory of its movement. The same effect is achieved if one item is half gone.

to the receiving part of the discharge chute 3, and the other part is pressed from the wall of the bunker 1 by a subsequent part. This combination of the profiles of the slats 4 and 5 eliminates jamming and promotes the ingress of parts into the discharge tray 3.

Claims (2)

1. A loading device comprising a bunker, a work disk and a discharge tray with lower and upper bars, characterized in that, in order to ensure reliable operation, the receiving end of the lower bar of the discharge tray is made in the form of a triangular pyramid with an inclined side, a spiral transition radial surface with progressively increasing bevel. 2. The device in accordance with paragraph 1, clause 1, which is such that the receiving end of the upper rail of the discharge tray is located behind the sharp end of the triangular pyramid of the lower rail and the radius of the latter is eccentric relative to the axis of rotation of the working disk.
