The invention relates to the processing of metals by pressure and can be used to separate the piece stock from the foot and feed it into the treatment area.

The aim of the invention is to increase the reliability of operation.

FIG. 1 shows a device for separating a workpiece from a foot and feeding it into a treatment zone; in FIG. 2, view A in FIG. one; in fig. 3 - device, view in plan; in fig. 4 - carriage.

The device comprises a housing 1, a rack 2, a holder 3 with teeth 4 with a step equal to the feed step of the cassette 5 under the ejector 6 of the workpiece 7, the stops made in the form of protrusions 8 and 9, made in the carriage 10 installed in the guides 11, spring 12 and a leash 13.

 A replaceable cassette 5. with articles 7 is installed inside the casing 3 and secured with a spring-loaded conical latch 14. The cassette 5 consists of two cheeks 15 with grooves 16, the pitch of which is equal to the pitch of the teeth 4 of the cage 3 and into which the products 7 are mounted. keeps the products 7 from falling out and has oval windows 18 with a pitch equal to the pitch of the grooves 16 for the free passage of the ejector 6. The upper wall 19 of the cassette 5 has a tapered hole 2 for fixing the cassette 5 in the casing 3. In the vertical plate 21 of the housing 1 there is a window for exit products from the cassette.

A mandrel 23 is mounted on the horizontal plate 22 of the body for orienting and fixing the product 7. The stop 24

The spring moves in the direction of the cassette under the action of the spring and pushes the workpiece out of the cassette. The upper stop comes out of interaction with the lower tooth. The cassette under its own weight is lowered until the lower tooth interacts with another carriage stop. 4 il.

has an axis of rotation and serves to limit the movement of the product from the cassette 5 and does not prevent the removal of the product c. mandrels 23.

To signal the operator that the cassette is empty, under the plate 22 a microswitch 25 is installed, communicating with a limiter 26; 27 - the hand of a robot manipulated torus.

The device works as follows.

In the initial state, the arm of the robot 27 is located above the mandrel 23 and interacts with the driver 13 of the carriage 10, which is in the extreme right position, and the spring 12 is stretched. The yoke 3 with the cassette 5 and the products 7 is in the extreme upper position, while the lower tooth 4

the clips 3 are fixed on the projection 8 of the carriage 10, and the ejector 6 is located outside the limits of the cassette.

By turning the arm of the robot 27 by the spring 12, the carriage 10 moves,

while the holder 3 with the cassette 5 and the products 7 under its own weight is lowered and fixed on the protrusion 9 with the same tooth 4. With the further course of the carriage 10, the ejector 6 fixed on the carriage 10 enters the lower oval window 18 of the rear wall 17 of the cassette 5 and pushes the product 7 through the window of the vertical plate 21 from the cassette 5.

The product, moving towards the mandrel 23, under the action of the ejector 6 reaches the stop 24 and is fixed on the mandrel 23. In this case, the side stops guide the product 7

in space, and the bar allows you to have the product on the mandrel 23.

When the robot arm 27 turns back, the arm interacts with the leash 13, which moves the carriage 10 and expands the spring 12. In this case, the lower tooth 4 of the yoke 3 leaves the engagement with the protrusion 9, and the yoke 3 with the cassette 5 lowers the next tooth The sleeves 3 are fixed on the protrusion 8 of the carriage 10. The ejector 6 comes out of the cassette 5. When the hand of the robot 27 is lowered, the product 7 is captured by the suction cup. The arm of the robot 27 is raised, while the stop 24 is undermined on the axis and does not prevent the product from being removed from the mandrel 23.

By turning the arm of the robot 27, the next product 7 is pushed out and fixed.

When the last item 7 is pushed out of the cassette, the stopper 26 presses the microswitch 25, which operates and signals the operator that the cassette is empty.

In order to charge the new cassette during the operation of the complex, when the robot arm is above the mandrel, it is necessary to push the carriage 10 all the way to the right, while the tooth of the holder 3 is disengaged from the protrusion 8 of the carriage 10 and the holder 3 moves freely upwards. When releasing the carriage 10, the lower tooth 4 of the holder 3 is fixed on the protrusion 8 of the carriage 10. When removing the fixation
