Abstract

The invention relates to the field of mechanical engineering and can be used as a loading device for parts of complex shape with automatic feeding and unloading of the latter. The purpose of the invention is to expand the functionality by providing loading, turning and unloading parts of complex shape. When the mechanism for moving 2 parts into operation, the electromagnetic 9 9 grippers 11 are lowered in the direction of the stack of 26 parts. A lift 7 is turned on, lifting the stack of 26 parts, and the electromagnetic grippers II are aligned with the plane of the upper part. Electromagnetic grippers 11 are turned on and, moving up, they seize the top part from stack 26, and then the part moves to working position 25 on the tiller 6 parts.

Description

The invention relates to mechanical engineering and molset be used as a loading device for parts of complex shape with automatic feeding and unloading of the latter.

The purpose of the invention is to expand the functionality due to the possibility of loading the turning and unloading of parts of complex shape.

Fig, 1 shows the device, a general view; FIG. 2 shows the mechanism for feeding parts in the initial position in FIG. 3 the same, at the time of basing-NIN. electromagnet1 x grips on the part plane; in fig. 4 is a view A of FIG. 1; in fig. 5 - incision bb fit. one; in fig. b - view B in FIG. 5; in fig. 7 the latch with lock is locked at the moment of resetting the part.

The device contains a base on which the mechanism 2 for supplying parts with a drive, a mechanism 3 for moving parts with a drive 4 mechanisms and 5 for unloading parts with a corresponding drive, a tilter for 6 parts are placed.

The mechanism 2 feed parts contain a lift 7 with placed on whom many

the cassette 8, the drive 9 of the lift 7. The latter is equipped with the inputs 10 j input w Dmi in the initial position between the micron, the burner cartridge 8 k, with a stack of parts. The component feed mechanism 2 is provided with electromagnetic grippers 1 1 pivotally mounted on an additionally inserted movement block of said grips, made in the form of an i 2 rocker arm, two-arm lever 3 3 pivotally connected to one of the arms, the other of which is connected to the stem 4 of the power cylinder i 5 Electromagnetic 1 ): the grippers 1 1 are located along the edges of the rocker arm 12. In the area of the shift 11 (the rod 14 is located the track binder 6. The electromagnetic grippers i1 with the indicated displacement unit are mounted on the mechanism 3 for moving parts.

Mechanism 5 unloading parts performed

yen in the form of a chain conveyor 17 with an emphasis 18 and contains two guide tracks 19. At the exit of one of the guide tracks 9 is located with

the possibility of rotation in the vertical plane of the spring is spring loaded; On the strap 20. Mechanism 5 unloading details also contains a lock,

;

.

In the form of an L-shaped two-stage lever 21, mounted on the base i, it can be rotated 3 horizontal planes, one level 22 of which is arranged to interact with the stop 18, and the other level 23 - to interact with the spring-loaded one. whipping 20 strap

In order to ensure the sequence of the cycle of operation of the lift 7 and the power cylinder 15, a positioning switch 24 is placed on the mechanism 3 for moving parts. The device is adjacent to the working position, for example an assembly wheel 25.

The device works as follows.

A dual-powered cassette 8 with a loaded HbiKH stack of 26 parts is mounted on a lift 7. An automatic work cycle is started.

The first stack of 26 parts moves up to the engagement with the hooks 10 of the hoist 7. The ci-stitch 1 cylinder 15 has been turned on, the rod 14 of which 5 is pushed forward, extends the arm of the two shoulders 13 in the directions of the longitudinal shaft of the above-mentioned power cylinder. At the same time, the other shoulder of the two shoulders lever 13 with the beam 12 and the electromagnetically supported grippers i 1 is lowered in the direction of the stack of 26 parts. At the end of the stroke of the two shoulders lever 13, the limit switch I6, including the lift, is activated. 7 J. The hooks 10 of which lift up a stack of 26 parts. Electromagnetic grippers II with a rocker arm 12 are twisted along the plane of the upper part in the headquarters. Upon further movement of the stack of 26 parts upward, the force of the lift 7 is transmitted to the shoulder of the two shoulders lever 13 connected to the beam 12. The indicated extension noBOpa4JiBaeTCHj overcoming the resistance of the power cylinder 15j, is released; the trip switch 1 b, disconnecting the lift 7 and turning on the electromagnetic grippers II,

The power cylinder 5 is turned on to rise, the rod 4 extends and through a double-arm lever 13 raises the rocker arm 2 from the gripped electromagnet and grippers 1 1 part above the stack of 26 parts. The yoke 12 at the end of the stroke is pressed to the lower plane of the C1-SHOVEL cylinder -15 and the fixed piece is set parallel to the plane 31

bones turner 6 dead; to her. The drive 4 of the mechanism for moving 3 parts is turned on and transmits the last to the tilter 6 parts. The electromagnets 11 are turned off and diverted to the loading zone. A working position, e.g. an assembly head 25, is included in the process operation. At the end of this process, the turner 6 of parts is rotated and transfers the part to the guide tracks 19. The chain drive is turned on. the conveyor 17 and the uper I8 moves the part, based on the end of the stroke on the spring-loaded, latch bar 20,

After that, the stop 18 interacts with the latch stage 22, as a result of which the latter rotates and the other latch stage 23 emerges from under the spring-loaded locking bar 20.

The latter is rotated in a vertical plane by the weight of the part and the part enters the space formed on the dispensing conveyor (not shown).

Further, the cycle of operation of the device is repeated.
