Description

 one

The invention relates to mechanical engineering and can be used to load process equipment.

The purpose of the invention is to expand the technological capabilities of the device by ensuring the supply of different shaped parts.

The drawing shows a device for issuing parts, a general view.

The device contains a magazine 1 for parts 2, having a number of vertical cassettes 3 with inclined shelves 4.

The magazine 1 is mounted on the rack 5, it can turn from the drive mechanism 6, which ensures the sequential reversal of the store faces to the unloading position by means of the manipulator.

Store 1 has the shape of a polyhedron, on each face of which between rows of shelves at least one window is made, with a probe 7 and two cheeks 8 on each face of the store, ensuring fixation of workpieces on rigid stops in a horizontal position during installation and their subsequent movement on the schag.

On the rack 5 there is a parallelogram mechanism containing two hinged levers, two vertical links, one vertical link in the form of a carriage 9 and mounted on the vertical rack 5 with the possibility of movement and connected to the damper 10, and the other link in the form of strips 11 with a vertical row of rigid stops 12 facing the window.

The carriage 9 and the bar 11 are interconnected uppermost. 13 and lower 14 oblique links. Moreover, the upper inclined link 13 is connected with the power cylinder of the drive 15 lifting 1 and.

In addition, the device for issuing parts is equipped with a number of position sensors of the actuating mechanisms of the loaded device. Thus, the sensor 16 serves to monitor the presence of parts on the edges of the magazine, which is carried out with the help of the probe 7. The sensors 17-18 serve to monitor the position of the bottom links 13 of the bar 11 and to transmit commands to the actuators of the loaded device. Sensors 19-20 are used to monitor the position of the carriage 9 and transmit commands

actuators boot device. Sensors 21-22 serve to monitor the position of store 1 and transfer the command to the executive mechanisms of the boot device.

The device works as follows.

Parts 2 are manually loaded onto the inclined shelves 4 located on the vertical cassettes 3. The parts 2 are removed by a robot or a manipulator made from the top bar 4 from the discharge area. If there is a part on the top shelf 4, part 2 presses the probe 7, which is in contact with the other end of the sensor 18. Sensor 16 gives a command to the robot or manipulator to remove the part from the upper shelf 4. gives a command to trigger the lifting mechanism 15, which rotates the bar 11 radially, up to the position when its inclined links will take the horizontal position, and the vertical link with rigid stops through the window of one of the store faces beyond the inclined shelves are located x on

30 facets of the store. When moving the strap 1 1 with stops, the latter removes 4 parts from the slats and presses the sensor 18, which gives a command to the damper 10 for actuation and further vertical raising of the carriage 9 with the bar 11. When the carriage 9 is moved with the bar up, the carriage presses the sensor 19, which gives the command to the mechanism of the drive 15 of the bracket for its transfer through the window of shop 1 by

radius down. After moving the strip 11 radially down, the latter presses the sensor 17, which commands the actuators

45 to act on a damper 10, with which the carriage with the bar mounted on it moves downwards, i.e. the bar occupies the original position. Then the cycle is repeated until the parts run out from the discharge area.

Then the sensor 16 commands the drive mechanism 6 to idle, 55 i.e. The cylinder rod presses the sensor 22, which commands the drive mechanism 6 to rotate magazine 1. The drive mechanism shaft 6 presses the sensor 21, which commands the robot to pick up parts.

from shelves 4 of the next facet storeg. Then the cycle repeats.
