Abstract

The invention relates to mechanical engineering, in particular to the automation of production processes, and can most effectively be used when loading metalworking machines and automatic lines. The aim of the invention is to simplify the design. The device comprises a base 4, a hopper 1 in which a feeder is installed which can be rotated, made in the form of a knife 8, an orientation mechanism made in the form of a spring-loaded rod 17 with a notch 18 on a working surface installed with a possibility of reciprocating movement along the inclined tray 14, coupled with a discharge channel, and interacting with the drive of the feeder by means of a lever mechanism, the turners 12, installed opposite to the feeder parallel to the latter, with the possibility of swinging and kinematically connected s drive of the feeder. The working surface of the agitators is made in the form of a wedge. The feeder individually feeds the parts into the inclined chute 14. If the part comes with a trunnion, it goes inside the recess 18 of the rod 17, while the second end thereof fails. The part, turning over, is fed by this end into the discharge channel.

there is a base 4, a hopper 1 in which a feeder is installed, which is made in the form of a knife 8, an orientation mechanism, made in the form of a spring-loaded rod 17 with a notch 18 on a working surface, installed with the possibility of reciprocating along an inclined tray 14 connected with a channel inlet, and interaction with the drive of the feeder by means of a lever mechanism, turners 12, installed opposite to the feeder parallel to the latter with the possibility of swinging

and kinematically coupled to the drive of the feeder. The working surface of the agitators is made in the form of a wedge. The feeder individually feeds the parts to the inclined chute 14. If the part comes with a trunnion, it goes inside the recess 18 of the rod 17, while the second end thereof fails. The detail, turning over, comes this end to the outlet, channel. If a part gets into an inclined tray with a pin in the back, it does not turn over and enters the discharge channel. 2 hp f-ly, 4 ill.

The invention relates to mechanical engineering, in particular to the automation of production processes, and can most effectively be used when loading metalworking machines and automatic lines.

The aim of the invention is to simplify the design by eliminating the drive of the orientation mechanism.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. I; in fig. 3 is a diagram of the orientation of the part when moving the pin forward; in fig. 4 - the same, when moving the rear axle.

The device contains a bunker I and a housing 2, which are joined together and mounted on racks 3 and base 4. In addition, an axle-acting drive shank - pneumatic cylinder 6 is hinged to the base 4 on the rack 5. The pneumatic cylinder 6 is pivotally connected to the end G a different lever 7 feeder. The feeder is an arcuate knife 8 and passes inside the hopper 1 through the guide channel 9, with the working surface of the knife 8 made in the form of a prism in the middle and with shoulders along the edges. The feeder is hinged on the axis 10 to the bracket 11 of the housing 2. In addition, On the same axis 10, the agitators 12 are swung, which are L-shaped levers with a collar 13 to restrict movement. Inside the housing 2, the inclined tray 14 and the discharge channel 15 are mounted.

Inside the inclined chute 14, an orientation mechanism, made in the form of a rod 17 spring-loaded with a spring 16, is moved with a notch 18 at the end. By means of the spherical head 19, the rod interacts with the rolled surface of the middle axis 20 of the lever system. The lever system is made in the form of four lamellar levers 21 and 22 fixed in pairs on Three Axes, one extreme axis 23 of which is fixed on the fixed bracket 24, and the other axis 25 on the lever 7 of the feeder.

The turners 12 are parallel to the feeder knife 8 and pass through the channels

26 hopper 1 at a distance from the knife slightly larger than the diameter of the part. At the lower end of the knife 8 attached strap

27dl impact on the agitators 12. The device operates as follows.

When the position of the pneumatic cylinder rod 6 is extended, the knife 8 is recessed in the guide channel 9 of the bunker 1 to slide the part into it. When the scraper is drawn inwardly into the pneumatic cylinder 6, the knife 8 rises, entrains the blanks caught in it, and in the extreme upper position transports the front of them to the inclined chute 14 of the housing 2, where the workpiece already meets the rod 17. When approaching the upper position, the knife 8 , the bar 27 lifts the agitators 12. During the return stroke of the pneumatic cylinder 6, the knife 8 is lowered, carries the agitators 12 behind, while the rod under the influence of the spring 16 begins to accompany the part when the middle axis 20 of the lever system is withdrawn.

When the parts hit the inclined tray 14 with a pin forward, the latter goes inside the recess 18 of the rod 17, the second end of the part fails and, turning over, the part enters this end into the outlet channel 15.

When the workpiece gets into the inclined tray 14 with a trunnion behind the other end of the billet, it cannot enter the recess 18 of the rod, and when the center of gravity Q passes beyond the edge, the billet does not turn over, falls and enters into the outlet channel 15 with the trunnion from behind.

When the pneumatic cylinder 6 is retracted, the rod 17 under the action of the axis 20 moves inside the inclined chute 14 towards the new blank.
