The invention relates to automatic loading devices, to machines and assembly machines and can be used in rotary and rotary conveyor machines for feeding piece parts with a pronounced center of gravity such as rings, flange washers of various configurations in width, bearings with a one-sided separator, etc. in oriented position. The purpose of the invention is to enhance the functionality of the loading rotor by ensuring that the transport chain feeds not only parts oriented in the storage unit under the action of the center of gravity, but also parts with opposite orientation.

FIG. 1 shows a loading rotor, a longitudinal section; in fig. 2 — node I in FIG. 1 (at the moment the part is fed into the slot of the turner); in fig. 3 and 4 - the same, at the moment of withdrawal of the turner from the accumulator; in fig. 5 and 6 - the same, at the time of removal of parts from the turner; in fig. 7 - the same, at the moment of the initial position of the tilter; in fig. 8 — node II in FIG. 1 (at the moment the part is fed into the slot of the turner); in fig. 9 and 10 - the same, at the moment of withdrawal of the turner from the accumulator; in fig. 11 and 2 - the same, at the time of removal of parts from the turner; in fig. 13 - the same, at the moment of the initial position of the tilter; in fig. 14 is a view A of FIG. eight; in fig. 15 is a view B in FIG. 9.

The loading rotor consists of a base 1 with a cup 2 rigidly fixed on it, on which copier 3 and stand 4 are mounted. On stand 4, a hollow shaft 7 is mounted through bearings 5 and 6 rotatably (not shown). In the upper part of the shaft 7 a hopper 8 is installed with gripping bodies uniformly placed around its periphery, made in the form of flat rectangular trays 9, passing into rectangular shaped accumulators 10 with two limiters 11 at the end.

On accumulators x 0, mechanisms of 12 single output were mounted. On the shaft 7, under the accumulators 10, there are fixed pullers with conical levelers 13 installed coaxially with the respective accumulators 10 and fixed on the disk 14. Coaxially conical levelers 13 with the possibility of reciprocating movement from the sliders 15 connected to the copier 3 by means of rollers 16 and placed in the drum 17, mounted on the shaft 7, installed tilters 18. The latter are in the form of a rod, the upper end of which is made in the form of a two-pin plug with an outer conical surface 19 and an inner surface formed by successively located straight groove 20, parallel to the larger side of the accumulator 10, two projections 22 opposed to each fork 21 and a heart-shaped groove 23. In this case, the surfaces of the projections 22 are smoothly connected to the surfaces formed by the grooves 20

and 23.

Each tilter is installed in such a way that, at its highest point, the straight groove 20 is an extension of the straight groove 10 on its larger sides, and the perpendicular smaller sides of the rectangular bucket 10 overlap the straight groove 20 from the sides with two limiters 11 mounted on the smaller sides of the drive 10 and serving as a continuation of its internal surface.

Under the disk 14, on the shaft 7, there is mounted a lever 24, which bends around the conveyor 25, on which the carriers 26, mounted coaxially to the pullers with leveling devices, are fixed.

A drum 17 and a gear wheel 27 connected to a drive (not shown) are fastened on the underside of the hollow shaft 7 for 0. For parts oriented towards the center of gravity, the inner surface of the two-pin plug is made by successively located straight groove 28

5 and perpendicular to it a rectangular groove 29, joined by radius surfaces 30, where the width of each groove is equal to the width of the inner surface of the storage ring. Boot rotor works as follows

in a way. 0

When the rotor rotates the toothed wheel 27 from the drive, the sliders 15 with the tilting devices 18 fixed on them receive a reciprocating movement from the copier 3. Parts 3 are poured into the hopper 8, mixed, oriented during rotation of the rotor, and through flat rectangular trays 9 fall into rectangular drives 10 in a vertical position. When raising the slider 15, in the highest

0 its point, tilter 18, in the upper part having the form of a two-fork, takes up such a position in which the straight groove 20 (the gap between the forks of the fork) of the tilter 18 is an extension of the rectangular drive 10 along its larger

 the sides, and the limit stops 11 of the rectangular storage ring 10 block the straight groove 20 of the tilting device 18 from the sides, thereby creating a closed volume into which the special junction 31 is japped, j is the rear part 31. When the tilter 18 is lowered with part 31, the limiters 11 the vertical part 31 is not allowed to roll to the side. Standing vertically on one of the protrusions 22 in the straight groove 20, the part 31 begins to slide along the protrusion 22,

55 deviate from the vertical in the opposite direction with respect to its deflection under the influence of the force of gravity, push the quill with 21 two-pin plugs, on the ledge 22 of which it rested at the highest point of the turner 18.

When the two protruding plugs 22 from the protrusion 22 of the fork protrude, the part 31 with its lower part starts to enter the heart-shaped groove 23, at the same time continuing to deviate from the vertical and fit onto the same feather of the two double-pin plugs.

The void in the heart-shaped groove 23 with its lower part, the part 31 is finally tilted to a horizontal position, sitting down on the feather 21 of the two-pin plug and held in this position by two points: the bottom end of the heart-shaped groove 23 and the bottom surface of the other protrusion 22, from the heart-shaped groove dvuhperoy fork.

Upon further lowering, the tilter 18 with the part 31 oriented to a horizontal position passes through a puller with a conical leveler 13. The axis of the part is shifted relative to the axis of the leveler. When moving the turner 18 down, it passes through the position when one side of the part 31 lies on the conical surface of the leveler 13, the other in the heart-shaped groove 23 of the two-pin plug. The part 31 begins to change its position, moving towards the vertical due to the fact that the point of the part 31 on the conical surface of the leveler 13 temporarily remains in place, and the tilter 18 with the other part of the part 31 goes down. This part of the part 31 simultaneously with the movement of the tilting device 18 leaves the heart-shaped groove 23. When the part 31 is at an angle of 30-45 ° to the horizontal, it goes out of the heart-shaped groove 23 into the free zone between the protrusion. 22 two-way fork and freely passes the positioner 18 down, while remaining in place in an inclined position. Further, from an inclined position, sliding along the conical surface of the leveler 13, the part 31 is centered therein and falls into the carrier 26 of the conveyor 25. The tilting device 18, having passed through the carrier 26 of the conveyor 25, goes down. Then the cycle repeats.

When the parts are oriented towards the center of gravity at the highest point of the tilting device 18, the part 31 from the piecewise delivery mechanism 12 is loaded into the straight groove, similarly to the one described above, and rests with its lower part on the lower end of the rectangular groove 29. When the tilting device is lowered, the workpiece 31 tilts in the direction of gravity because its center of gravity is ridiculous, rotates in a rectangular notch 29, slides over the feather of 21 two-pin plugs and takes horizontal

the position held in the rectangular slot 29 is cantilevered. Upon further lowering of the collar 18, the part is removed by a puller from a fork, similarly to that described above.

and fed into the transport chain.

Compared to the known, the proposed loading rotor allows the transport chain to provide both the parts oriented with the center of the t-rod and the parts oriented with the opposite side, which expands its functionality.
