SU984808A1 - Apparatus for charging parts such as bodies of revolution - Google Patents

Description

The invention relates to automation · technological processes in mechanical engineering and can be used when loading metalworking and assembly equipment.

Known devices for loading parts such as bodies of revolution, containing a multi-groove magazine with cut-offs of a number of parts and a receiving platform installed with the possibility of plane-parallel and rotary motion [1].

The disadvantage of this device is the need to stop the receiving platform in a fixed intermediate position to ensure the issuance of the lower 'row of parts and fixing the previous row of parts in the store.

The purpose of the invention is to increase the productivity of the device by reducing the loading cycle of parts having a hole by eliminating the need to stop the receiving platform in a fixed intermediate position.

This goal is achieved by the fact that the cutoffs of a number of parts are made in the form of a multi-groove magazine mounted on the wall at the level of the bottom row of parts of the cutter rods and their drive mechanism in the form of a plunger installed in the body with a transverse shaped pass, including vertical and inclined at an angle to axis of the plane plunger, while the plunger and the cutting rods are interconnected by an additionally introduced spring-loaded bar, and a plunger position lock and lkatel cooperating with locking position of the plunger, with the figure of the groove and inclined plane with a receiving platform.

In FIG. 1 shows a device, a general view;> in FIG. 2 is a section AA in FIG. 1 (with a receiving platform located in the lower extreme position); in FIG. 3 - section AA in FIG. 1 ^z (with a receiving pad located in the upper extreme position); in FIG. 4 is a section BB in FIG. 1 (according to the drive mechanism of the cut-offs and cut-off rods).

The device has a multi-hole magazine 1, filled with parts 2, and a receiving platform 3 with a mechanism 4 for the individual issue of parts. On the vertical wall of the store 1, in the location of the lower row of parts 2, two bodies 5 are fixed, in which plungers 6 with a figured groove are installed

7. The pusher 8 and the clamp 9 of the position of the plunger 6 are installed in the figured grooves 7. The figured groove 7 has a protrusion 10 interacting with its inclined plane 11 with a pusher

8. The plunger 6 using a spring-loaded strap 12 are connected to the cut off · -. thrust rods 13. A spring-loaded stop 14 is also installed on the vertical “wall of the magazine 1, interacting on one side with a pusher 8 and with a micro switch 15 on the other. The receiving platform 3 is pivotally mounted and connected to the drive, made in the form of a pneumatic cylinder 16, using a strap 17 fixed to the guide rods 18. A stop 19 is mounted on the strap 17, which interacts with the pusher 8. In the lower extreme position, the receiving platform 3, with the help of the stops 20 and 21, it is located at an angle to the horizontal plane, which ensures the free movement of the parts 2 when the mechanism 4 of the single-piece issue of parts is triggered.

The device operates as follows ..

In the initial position, the parts 2 located in the trays of the store 1 are held by the cutting rods 13 and the plungers 6.

The receiving platform 3 while without parts 2 is in the lower extreme position on the stops 20 and 21.

When you turn on the pneumatic cylinder 16, the receiving platform 3 is moved to the upper extreme position. As the receiving platform 3 approaches the upper extreme position, the stop 1.9 interacts with the pusher 8. In this case, the pusher 8, overcoming the resistance of the spring-loaded stop 14, moves up. At the same time, the pusher 8, interacting with the inclined plane 11 of the figured groove 7, moves the plungers 6 to the right extreme position. At the same time, the cut-off rods 13 connected with the plank 12 with the plungers 6 also move to the right extreme position ^J and release the lower row of parts 2 located in the multi-groove magazine 1. When the plunger 6 moves to the right extreme position and the pusher 8 is in the upper extreme position, the lock 9 interacts with the lower protrusion of the pusher 8 and enters the groove of the housing 5, fixing the plunger 6 in the right extreme position.

In the upper extreme position of the pusher 8, the spring-loaded stop 14 interacts with the microswitch 15, from. which receives a signal to switch the pneumatic cylinder 16 to return the receiving platform 3 to its original position. When moving the receiving platform 3 to the initial position of the plunger 6 And the associated shut-off rods 13 are in the right extreme position. In this case, the parts 2 located in the multi-groove store 1 are moved together with the receiving platform 3-. _g In contact with the upper protrusion of the pusher 8 with the latch 9, the latter comes out of the groove 7 of the housing 5, freeing the plunger 6 from fixing. In this case, the plungers 6, and with them the shutoff rods 13, under the action of the spring-loaded bar 12 return to their original position and fix the next horizontal row of parts and thereby hold the columns of parts in the myoglottic magazine 1. Upon returning to the initial position, the receiving The platform 3 is located on the stops 20 and 21 at a certain angle, which ensures the free movement of the parts when the mechanism 4 of the single-piece issue of parts is activated. After the consumption of parts located at the receiving platform, a signal is sent from a sensor (not shown) to turn on the pneumatic cylinder 16 to repeat the operation of the device.

This design of the device eliminates the need to stop the receiving platform in a fixed intermediate position, thereby shortening the cycle, and therefore increase the productivity of the device.
