Description

The invention relates to machine tools, namely, devices for automatic loading of technological machines with piece goods, and can be used for loading rotary and rotary conveyor machines and LIN11Y piece cylindrical products.

The aim of the invention is to increase the reliability of the rotor power supply by interfacing the straight lines of the conical surface of the gripping funnel with the conical surface of the hopper and the internal opening of the cylindrical chute.

FIG. 1 shows a rotary power feed; general view; in fig. 2 — node I in FIG. one; in fig. 3 is a view A of FIG. 2

The rotary powering machine contains a hopper 1, on the periphery of the bottom part of which the gripping funnels 2 with a conical surface, whose rotation axes are inclined to the horizontal plane at an angle oi, are evenly placed. Each hopper 2 has a gear 3 that meshes with the stationary a ring gear A rigidly mounted on a fixed rack 5. The gear 3 is mounted on rotational supports 6 fixed on the chute 7. The streams 7 are located under the funnels 2 and fixedly fixed in the disk 8 rigidly connected with b anchor 1 with poles 9. A disk 8 is rigidly fixed on a beaker 10 mounted rotatably on a fixed stand 5 from a fixed gear 11 attached to it. Each estrus 7 has a splitter 12 driven by a fixed cam 13.

To eliminate the pressure of the upper layers of products 14 on the bottom, located directly in the grip area of the craters 2, the bunker 1, in which the stock of non-oriented products is stored, has a conical shell 15, which forms a pre-bunker with the walls of the bunker 1, and with a fixed surface the conical bottom 16 is an annular gap, which makes it possible for articles 14 to enter the rotating funnels 2. The conical bottom 16 is rigidly fixed on the fixed rack 5 and serves to direct the products to the funnels.

For smooth transfer of products from the conical bottom 16 to the fixed chutes 7, the conical surface of each gripping funnel 2 is set to -5 so that it forms common lines with the bottom 16 of the bunker 1 and the internal hole of the chute 7.

In order to increase the efficiency of capturing products on the tapered surface 0, each gripping funnel 2 has uniformly spaced radially directed notches 17, the depth of which is equal to 1/2 of the diameter of the products .14. This depth of the grooves ensures that the products 5 are reliably seized by the 14 cavities 17 and the products they captured are transported from the lowest forming cone of the funnel to the highest forming as a result of rotation.

A part of the outer surface of the chute 7 protrudes above the inner conical surface of the gripping funnel 25 2, forming a protrusion 18, perpendicular to the conical surface of the gripping funnel 2. The maximum height of the protrusion is 1/2 of the product diameter 14. This height of the protrusion 18 is the optimum 2Q on the surface of the product, captured by the recesses 17, until the moment of sinking into the hole of the heat 7, product 14.

Rotary power supply operates as follows.

In the process of transporting rotation of the rotary power unit, a relatively fixed rack 5, communicated to it from the drive of the rotary technological machine (line) fed by it through gear 11, gripping funnels 2, rolling its gear 3 along the fixed gear crown 4, rotates around its own axes.

A portion of the outer surface of the chute 7 protrudes above the inner conical surface of the gripping funnel 2, forming a protrusion 18, perpendicular to the conical surface of the gripping funnel 2. The maximum protrusion height is 1/2 of the product diameter 14. This height of the protrusion 18 is optimal for holding it the surface of the products captured by the grooves 17, until the moment of sinking into the hole of the heat 7 of product 14.

The products are gripped by 14 grooves 17. As a result of the rotation of the gripping funnel 2 around the axis of the product 14, the gripped recess

At the moment of coincidence of the recesses 17 with the products 14 with the inner surface of the chute 7 of the product 14 enters the cylindrical chute 7. The interaction of the cutters 12 with the fixed cam 13 provides a single delivery of the products 14 of the cylindrical chute 7 into a transport device (rotor or chain) of a rotary technological machine (line).
