The invention relates to the automation of technological processes in mechanical engineering and is intended for the oriented feeding of cylindrical objects of small elongation.

The purpose of the invention is the expansion of technological capabilities.

FIG. 1 shows the device, a general view; in fig. 2 - the same, top view} in FIG. 3 - wave cone, top view.

The device contains a base 1, a hollow cylinder 2 with blades 3, inside which the additional cylinder 4 is fixed. The cylinder 2 is mounted on the supports 8 with the possibility of rotation from the gear teeth 9 of a drive (not shown). On the inner side of the hollow cylinder 2 along its generatrix, blades 3 are mounted with uniform pitch to move objects along the rifle grooves 5 from the inlet 10.

A funnel 11 is installed above the hollow cylinder 2;

The racket 11, together with the surface of the cone 6, forms a V-shaped opening for the passage of objects. The funnel 11 is mounted on the supports 15 and has an individual drive (not shown) with a wedge-belt transmission 16. The grooves of the wave-shaped cone 6 are made in a spiral, mainly in the Archimedes spiral, and the taper and pitch of the spiral are chosen from the condition of sliding objects in grooves under their own weight in m gamma 17. The width of the blade 3 in cross section is chosen from the condition of providing the required frequency of feeding the oriented objects to the tray 18.

The device works as follows.

shaft oriented objects. Objects arrive at the wave-like cone 6 and the surfaces of the radial cavities 12 of the funnel 11, and then slip into the V-shaped opening formed by these surfaces.

The radial cavities 12 of the funnel 11 begin to mix the loaded mass of objects, arrange one lx one by one in the cavities of the wavy cone 6 and orient relative to part of the intersection lines of the surfaces 13 and 14. The objects placed in the cavities of the wavy cone 6 are cut off by the projections of the radial cavities 12 of the funnel 11 from the total mass of the objects located above them, and slide along the depressions of the cone 6 on the surface of its lower part. The following objects are placed on the vacant space in these depressions of the X-rays of the doublet1 12 funnels 11, which similarly slide off behind the front end. This happens until the depressions of the wave-shaped cone 6 are filled with objects throughout . In this case, the radial depressions 12 of the funnel 11 move the objects without disturbing the specified order, since the depth of the depressions of the cone 6 is not larger than the diameter of the object.

Objects, hitting the surface of the lower part of the cone 6, are picked up by the blades 3 of the rotating hollow cylinder 2 and are unimpeded between them, since the recesses are made on the cone 6 in a spiral, and the spiral is an Archimedes spiral that allows them to be positioned approximately tangential to the displacement of objects by the blades 3, which provide the best entry of objects into the spaces between the blades 3. This is facilitated by the arrangement of the objects in the recesses of the cone 6 one after another, ec-to-end, as the first is located in these recesses of the subject affects all subsequent weight behind it objects.

Placed between the blades 3, the objects move along the surface of the lower part of the cone b around the circumference and Hai-on their way to the inlet 10 all the leaks are passing, in which the objects are or are not. Those

the objects that are in the currents are repelled by the blades 3 and the cylindrical surface of the objects, preventing them from violating this order. If the object could not be placed in the gap with a blade 3, then on. On his way to the inlet of Yu he always encounters a leak in which there are objects to be placed.

The objects move between the blades 3 until they find an inlet 10 on their way. Through it they enter the helical grooves 5 of the additional cylinder 4. In this case the gap between the blades 3 is freed from the object to place the next item in it, but the blades 3 continue to move further

spiral grooves 5.

since their depth is less than the diameter of the object, and the blades are extended along the length of the generatrix of the hollow cylinder 2 and have a smaller width in the lower part just for such movement of objects.

The movement ends after the objects exit the helical grooves 5 through the outlets and lower onto the tray 18 in the oriented position. As a result

In this case, all the objects covered in the funnel 11 fall into the subsequent technological operation in a correctly oriented position with a given rhythm.
