Description

The invention relates to the field of mechanical engineering and can be used to feed parts into machine tools and automatic assembly machines, as well as to collect parts in a stack / cassette /. .

A device for feeding parts, containing a magazine with a table mounted on the rail, a table moving mechanism in the form of a fixed wedging mechanism and a spring-drive, a spring-loaded axle of the mechanism for controlling, interacting with the gripper of the manipulator 11, is known.

The disadvantage of this device is the limited technological capabilities of the application due to the difficulty of its readjustment to another size of parts.

Another device for feeding parts is known, which contains a magazine with a table mounted on the rail, a gripping arm, a spring-loaded pusher of the control mechanism, a mechanism for moving the table rail in the form of a fixed and movable jamming mechanisms with locking elements t2.

A disadvantage of a cooked device is the complexity of the design and the limited ability to cassette the parts into a stack.

The aim of the invention is to simplify the design and expand the technological possibilities of its application.

This goal is achieved by

10 that in the device the fixed jamming mechanism is installed with the possibility of interaction with the table rail under the action of a spring-loaded pusher, the weight of the table and the foot

15 details.

In addition, the spring-loaded pusher of the control mechanism is provided with a stop mounted for movement in a horizontal direction 20. The movable wedging mechanism is provided with pre-deformed springs and springs mounted respectively at the top and bottom of its stopper elements,

25a, the control mechanism is provided with a linkage connecting a spring-loaded pusher with a movable wedging mechanism.

FIG. 1 shows a general view of a device for feeding parts into a gripper.

manipula torus; in fig. 2 is a general view of a device for feeding parts into a stack and lowering it to a certain level; in fig. 3 is a general view of a device for feeding parts into a stack and lowering it by a certain step. t

The device for supplying parts contains a magazine 1 with parts 2, a table 3 fixed on a rail 4, a control mechanism in the form of an emphasis 5, a pusher 6 with a spring 7, locking elements 8 (rollers), a fixed jamming mechanism 9, a gripper 10 of a manipulator 11, an actuator 12 with a piston 13, a rod 14 with a spring 15, a movable wedging mechanism 16, an adjustable stop 17, pre-deformed springs 18 with rods 19, springs 20, and tgu 21.

The device works as follows.

In the first case (Fig. 1, a foot is supplied for parts up to a certain level.

After removal of the manipulator 11 with the part, the stop 5 takes up the initial position above the foot of the parts 2. After this, the drive 12 is turned on. When the piston 13 and the rod 14 move upward, the jamming mechanism 16 stops the rail 4 of the table 3 and lifts the stack of parts 2, the stop 5 and the pusher 6. At the time of this lifting, the stationary wedging mechanism 9 splits the rail 4, and its elements of the locking 8 floor force the springs to move up to the stop into the pusher 6. The stroke of the rod 14 is limited by the stopper 17 through the wedging mechanism 16. Drive 12 after the upward movement off. At the same time, the piston 13 is lowered down, and together with it the moving jamming mechanism 16, rake 4, table 3 with a stack of parts 2, the stop 5 and the plunger 6 are lowered. At a certain stop, the elements of the stopper 8 of the stationary jamming mechanism 9 under the action of the spring 7 and the pusher 6 wedges the rail 4, stopping the movement of the table 3 downwards and at the same time providing a predetermined level of placement of the stack of parts 2 in the magazine. After stopping the rail 4, the porsche 13 of the actuator 12, together with the pusher 6 and the jamming mechanism 16, continues to move downward under the action of the spring 15, with THIS mechanism 16 wedging it out. After this manipulator tor 11, the gripper 10 takes the next part. Further, the cycle of operation of the device is repeated.

In the second case (Fig. 2), the parts are collected in a stack and lowered to a certain level.

In this case, the manipulator 11 supplies the part to the stack of parts 2, moving the abutment. in the horizontal direction. After its departure, the stop 5 comes onto the foot, raises the pusher 6 upwards by the thickness of the filed part and compresses the spring 7. Then the operation cycle of the device repeats. At the moment of release, the locking elements 8 of the moving jamming mechanism 16 are pressed with the springs 20 to the previously deformed springs 18.

The presence of deformed springs D8, the force of which exceeds the force of the springs 20, ensures the post onycKaHVie of the rail 4 downwards and its wedging by means of a moving jamming mechanism 16 at a level lower than its jamming in the subsequent cycle.

0 In the third case (Fig. 3, the parts are collected in a stack and lowered in a constant step.

For this, a manipulator 11 with a gripper 10 feeds the part to the foot of the parts 2 of the shop 2, and after it leaves and turns on the drive. 12 cycle operation of the device is repeated. However, the raising of the control mechanism pusher 6 is carried out through the pull 21 of the movable jamming mechanism 16 with the T2 drive. The step of lowering the rail 4 is set somewhat larger than the thickness of the details. This prevents the gripper 10 of the manipulator 11 from striking the foot of the parts 2. The step size for lowering the rail 4 can be changed by adjusting the length of the rod 21 and the rods 19.

i This device design allows to expand the area of its application, eliminate the static load on the manipulator, reduce the dynamic loads that occur during the movement of its links, and increase the speed of the manipulator.
