Abstract

The invention relates to mechanical engineering and can be used for the oriented supply of parts to machine tools and assembly machines. The aim of the invention is to increase the reliability of the device in operation due to forced turning of parts. Details of the type of bolts are supplied from the hopper 1 by the sector feeder 2 to the stops 9 of the guide pads 8 of the discharge chute 5. At the same time, the parts are oriented, occupying a vertical position on the plates 8. By means of the stop 6 fixed on the feeder 2, the discharge tray 5 is turned around the axis 3. At this rotation, the bracket 15 mounted on the base 16, interacting with the rollers 14, turns the catch lever 11 around the axis 13 and its fork 17, pressing on the levers 10, raises the part above the stops 9. The part under the action of its own weight moves along the levers 10 to the forks 17 of the catcher 11. During the return stroke of the feeder 2, the discharge tray 5 returns to a horizontal position, and the forks 17 orients the part from the vertical to the horizontal position, it is adjusted to the retainer 12.

The invention relates to mechanical engineering and can be used for the oriented supply of parts to machine tools and assembly machines.

The aim of the invention is to improve the reliability of the device due to the forced turning of parts.

FIG. 1 shows the device, ob- and view; in fig. 2 is a view. Of FIG. one; in fig. 3 shows a section BB in FIG. I, with a prism guide; in fig. 4 the same, with the direction of their lining; in fig. 5 shows a section B-B in FIG. 1, with a prism on the feeder.

A device for oriented feed of parts, preferably of the type of bolts, contains a hopper 1, a sector type feeder 2 mounted on axis 3 and connected to the drive 4 of its angular rotation. At the same time, an outlet tray 5 is installed on axis 3 with the possibility of angular rotation using stops 6 and 7 located on feeder 2.

The discharge tray 5 is equipped with guide pads 8 with stops 9 and cutter levers 10, as well as parts reorientation mechanism, made in the form of lever 11 and spring 12 relative to the outlet tray 5 and clamp 12. The lever 11 is mounted on axis 13 with the possibility interactions on one side with roller 14 with bracket 15 of base 16, and on the other with forks 17 with levers 10 cutters.

The feeder 2 is provided with guide bars 18 and a diverter 19 located above them for removing incorrectly oriented parts. The guide rails 18 of the feeder 2 and the overlays 8 of the discharge tray 5 are installed with the possibility of adjusting the displacement relative to each other.

The device can be used to supply items like ipiles. In this case, the guides G1: 1 of the tank 18 of the feeder 2 and the overlays 8 of the discharge tray 5 are replaced respectively with the prisms 20 and 1. I 1 is removed.

The device works with it.

Details such as bolts placed in the bunker 1 in bulk when turning the feeder 2 of the sector type under the action of the actuator 4 around the axis 3 are captured by its guide bars 18 and, westward between the I1el and depending on the head, interleave under the action of the proper weight on the guide pads 8 exhaust tray 5 until it stops 9. Incorrectly oriented parts are removed from the guides ri. iaHOK 18 feeder 2 diverter 19 located above them.

the weights are rotated from horizontal to inclined position. In the case of the hanging of the tray 5, the stop 7 turns it to the required inclined position.

The reorientation mechanism of the parts attached to the discharge tray 5 is rotated together with it. When rolling the roller 14 along the bracket 15 of the base 16, the lever-catcher 11, turning around the axis 13, turns with its fork fork 17 the levers 10 of the trimmer. The extreme part, located in front of the stops 9 on the guide plates 8, is lifted by the levers 10 of the shutter and, under the action of its own weight, moves into the forks 17.

When the drive piston 4 is retracted, the feeder 2, turning around axis 3 in the opposite direction, is lowered, and its stop 7 returns the discharge tray 5 to its original horizontal position.

In this case, the release lever 11, which is freed from interaction with the bracket 15, rotates around the axis 13 under the action of a spring, occupies a vertical position, and the trimmed part in its grip 17 can be turned from the vertical to the horizontal position.

Fixed on one side by the fork 17, and on the other side of the fixture 12, the part is captured by the manipulator and fed into the working area of the machine.

When using a device for feeding parts such as pins, the laths 18 on the feeder 2 and the linings 8 on the discharge chute 5 are replaced with prisms 20 and 21, respectively, and the lever 11 of the reorientation mechanism is removed.

The studs loaded into the bunker 1 in bulk are captured by the feeder 2 when it is rotated from the drive 4. West into the prism 20 and oriented, the parts are moved to the prism 21 of the discharge tray 5 in a horizontal position. The inclined position of the discharge chute 5 as a result of its joint rotation with the feeder 2 around the axis 3 allows the parts to move along the prism 21 to the latch 12 without changing the orientation oriented to the south.

After the return stroke of the feeder 2 and the horizontal position take-off tray 5, the outermost part before the retainer 12 is removed by the manipulator into the working area of the machine, and the cycle is repeated.
