The known feeders for the supply of piece goods, which contain an inclined frame with a wall-gate in the lower part, a lifting bucket moving along the frame guides, and a drain tray located at the upper edge of the wall of the gate, do not provide a portioned supply of cargo.

In order to provide portions of goods, the tray of the proposed device is hinged on a frame that can be rotated in a vertical plane under the action of a rising bucket and is equipped with a load arrival sensor that switches the bucket drive to descent.

In addition, in the proposed feeder, the goods receipt sensor can be made in the form of a movable spring-loaded comb with teeth protruding above the bottom of the tray through openings made in it and interacting with a limit switch mounted on the tray.

FIG. 1, 2, and 3 schematically depict the proposed feeder in three operating positions; in fig. 4 — part of the tray with the goods receipt sensor.

The feeder contains an inclined frame 1 with a wall-gate 2, a lifting bucket 3, open from the side of the wall and moving with the help of rollers 4 along the frame guides, a drive 5 for lifting the bucket 3 and a discharge chute b, installed on frame 1 with a hinge 7 and fitted with rollers 8 interacting with bucket tires 9 3. Tray b is equipped with a comb-in sensor, containing a beam 10 and a tooth 11,

protruding above the bottom of the tray b through the openings made in it.

The beam 10 is movably mounted on the fingers 12 attached to the tray 6 and provided with springs 13, and there is on the beam

stop 14, interacting with the limit switch 15 mounted on the tray b. In addition, on the bracket 16 of the frame 1 has a limit switch 17, interacting with the tray b, and in the upper part of the frame has a limit switch 18, interacting with the bucket 3.

Piece loads, for example, the forgings 19 are loaded into the bucket, after which the actuator 5 is turned on to rise, while the bucket is raised

and, acting on tires 9 on rollers 8, turns tray 6 upwards (FIG. 2).

After the bucket 3 passes over the top edge of the wall-gate 2, the weights 19 are poured onto the tray b and act on the tooth 11 of the sensor.

Under the influence of a certain portion of cargo 19, the beam 10 with the teeth 11, overcoming the resistance of the springs 13, lowers and the stop 14 turns the lever of the switch 15, while the actuator 5 switches over to the descent, bucket

3 is lowered, rollers 8 come out of contact with tires 9, tray b returns

to its original position and acts on the switch 17, which turns off the drive 5. The bucket 3 stops in an intermediate position, and the portion of weights 19 that arrived at the tray 6 is poured from it into the receiving tray 20 (Fig. 3).

Further, an adjustable technological pause between cycles is counted by means of a time relay, after which the actuator 5 is turned on to rise and the cycle repeats.

After the bucket 3 is completely emptied during its next lift, the goods receipt sensor does not work and bucket 3 rises up to switch 18, which gives the command to completely lower the bucket to its initial position.

Subject invention

1. A feeder for delivering piece goods, containing an inclined frame with a wall-gate in the lower part, a lifting bucket moving along the frame guides, and a discharge tray located at the upper edge of the wall-gate, characterized in that cargo, the tray is installed on the frame of the sharirio with the ability to rotate in a vertical plane under the action of a rising bucket and is equipped with a load arrival sensor that switches the bucket drive to the descent.

2. A feeder of claim 1, characterized in that the goods receipt sensor is made

in the form of a movable spring-loaded comb, equipped with teeth protruding above the level of the bottom of the tray through the openings made in it, and interacting with the limit switch mounted on the tray.
