Description

(54) DEVICE FOR ISSUING PARTS

one

The invention relates to mechanical engineering and can be used when loading machines and assembly machines.

A device for dispensing parts is known which contains a roller table, a magazine and a feeder mounted on the piston actuator rods and forming an articulated parallelogram with them for mixing, along a rectangular trajectory 1.

The disadvantage of the device is the fragility and complex control system of the feeder for a given trajectory of its movement.

A device is known, containing its gate feeder and lifting mechanism, made in the form of a hinged support arm and a copier 2.

However, the known device is unreliable in operation due to the presence of a multi-feed mechanism. The technological possibilities of its application are limited.

The purpose of the invention is improving the reliability of the device.

This goal is achieved by the fact that the lifting mechanism is provided with two stops placed on a slide gate feeder to limit the deflection of the support arm.

and a height lever, the copier being in the form of a linear cam with an inclined input and output part, and the support lever is mounted asymmetrically between the stops.

FIG. 1 shows the device at boot time, a general view; in fig. 2 - device at the time of unloading, general view; in fig. 3 - path of movement of the feeder; in fig. 4 is a view along arrow A in FIG. one; in fig. 5 is a view along arrow B in FIG. 2

The device contains a drive 1, gate feeder 2, height lever 3, the reference

10 lever 4, linear cam 5 with inclined input 6 and output 7 parts, stops 8 and 9, limiting the deviation of the asymmetrically suspended support arm 4 from the vertical to different angles, spring 10, 15, directional stop 11 and discharge tray 12.

The device works as follows.

When the drive shaft 1 moves to the left (see Fig. 1), the lever 4, which lies on the support 8, slides along the inclined entrance 6 of the linear cam 5 and raises the feeder 2 to the required height to pick up the part from the machine prism. In the unloading zone (see Fig. 2), the support arm 4 disengages from the linear cam 5 and lowers the feeder 2 below the level of the discharge tray 12, leaving part 13 on it. When the actuator stem 1 returns, the support arm 4 abuts against the inclined the output part of the linear cam 5, moves away from the stop 8 and rests on the stop 9, stretching the spring 10. Due to the asymmetrical arrangement of the axis of the suspension between the stops 8 and 9, the support arm 4 deviates from the vertical by an angle greater than during the forward running actuator stem 1, providing a lift in the feed l 2 to a lower level. In the loading zone, the height lever 3 rests on the directional pin, its stop 11, and the support arm 4, which has left the interaction with the linear cam 5, rests on the stop 8 under the action of the spring 10. The loading cycle repeats.

The proposed design of the lifting mechanism allows to expand the technological possibilities of using the device with the implementation of the movement of the feeder along a path of complex shape (Fig. 3).
