Description

The invention relates to machine mechanization and automated piece-by-piece workpieces for gripping the hand of an industrial robot and feeding it to the next manufacturing operation, for example, a press stamp, and can be used in sheet-stamping production in automatic lines based on industrial robots, billets to the press stamp and to dispense them from the stamp.

The aim of the invention is to reduce power consumption and increase device performance.

FIG. 1 schematically shows a device, a longitudinal section; in fig. 2 is a view A in FIG. on fig.Z - raerez BB in figure 1.

The magazine device comprises a base 1, on which a column 2 is installed with an internal cavity 3 and a vertical slot 4. The column 2 serves as an axis of rotation of the table 5 yr for the help of the rotation drive 6.

The drive 7 lifting the stack of blanks with the rod 8 is mounted on the column 2 above the rotary table 5 by the rod 8 down, while the rod 8 passes inside the cavity 3 of the column 2. The store device is equipped with a lifting fork 9, mounted on the rod 8 of the drive 7 of the lifting of the workpiece with a fixed at the end of the thrust washer 10, and having the ability to move in a vertical slot 4, made in column 2.

In the rotary table 5, in accordance with the positions from its center to each foot of the blanks, radial through-height slots 11 are completed, ending with slots 12 having a configuration, respectively, of the support washer 10. The initial position of the lifting fork 9 is below the rotary table 5, so that it does not prevents it from rotating.

On the turntable 5 mounted. Hbi interchangeable cassettes 13 with pins 14, between which a stack of blanks is laid. The housing 15 of each cassette 13 also has a slot-through slot 16 that coincides with the corresponding slots 11 and 12 of the turntable 5. The gripper 17 of the industrial robot is in the working position of taking the workpiece from the magazine device and transferring it to a die 12552482

sa Vertical slot 4 columns 2 is located on the side of the working position. The rotation drive 6 with the help of the bracket I8 is set to

5 to a hollow column 2 on its upper part 19 and kinematically through a gear transmission (gears 20 and 21) is connected with a drive sleeve 22 located outside the hollow column 2

10 and made with through slots 23 located in the same planes as the radial slots 11 of the turntable 5,

The device works as follows.

The turntable 5 has several positions. One of the positions is working, and the rest of the positions are used to load the replaceable empty cassettes 13 with blanks 24. At these same positions, the pins 14 can be rearranged according to the configuration and dimensions of the blanks 24. After loading by the KaticeT J3 operator, the blanks 24 turn on the drive 6 rotations of the table 5. The table rotates 5. During the rotation of the table 5, the rod 8 of the drive 7, the lifting of the foot 25 billets 24 together

30 with a lifting fork 9 and a supporting washer 10 are in their initial lower position so that the lifting fork 9 with the supporting washer 10 does not prevent the table from turning 5. Turning

35 of the table is carried out by a rotation actuator 6 fixed by means of a bracket 18 to the upper part 19 of the column 2, kinematically connected through a gear train (tooth 40 wheels and 21) to the drive sleeve 22 located outside the hollow column 2 mounted with rotary table 5 and made with through slots 23, located

45 in the same planes as the radial slots of the turntable 5. I

After finishing turning the table 5

its radial slot 11, one of the through slots 23 of the drive sleeve 22 and the vertical slot 4 of the hollow column 2 are aligned in the same plane.

The drive 7 for lifting the stoppers of 55 billets is turned on. Its rod 8, together with the lifting fork 9 and the supporting washer 10, is raised up. The rod 8 moves in the inner cavity

column 2, kinematically connected through a gear train (gears 20 and 21) with a drive sleeve 22 located outside the hollow column 2 mounted with a rotary table 5 and made with through slots 23, located

in the same planes as the radial slits of the turntable 5.

After finishing turning the table 5

its radial slot 11, one of the through slots 23 of the drive sleeve 22 and the vertical slot 4 of the column column 2 are aligned in the same plane.

The drive 7 for lifting the stand 25 of the blanks is activated. Its rod 8, together with the lifting fork 9 and the supporting washer 10, is raised up. The rod 8 moves in the inner cavity

3 of the hollow column 2. The lifting fork 9 moves in the vertical slot 4 of the hollow column 2, in the vertical through slot 23, filled in the drive sleeve 22 and together with the support washer 10 passes through the radial slot 11 and the slot 12 of the rotary table 5 and slot 16 in the case 15 of the cassette 13. During the movement of the lifting fork 9, the turntable 5 is locked from rotation and firmly fixed in a certain position. The support washer 10 during lifting rests on the bottom of the foot blank and the lift drive 7 raises the entire stack of workpieces by as much as the top foot blank does not reach the level from which the top blank is seized by the capture 17 of the extruded robot. After that, the lift drive 7, together with the stack of blanks, stops at this level.

The gripper 17 takes the workpiece 24 on top of the foot 25 and moves to the stamp f of the press.

After the grip 17 is pulling the top blank, the drive is 7 lifts

It is upwards by an amount corresponding to the thickness of the removed workpiece, constantly maintaining the top workpiece at a certain predetermined level. Thus, the drive 7 for lifting the stack of workpieces works upward until the end of the workpieces stops completely. Thereafter, when the cassette 13 is empty, the drive 7 for raising the stack of blanks is turned on in a downward motion. Its rod 8, together with the lifting fork 9 and the supporting washer 10, are lowered to the lowest position so that the lifting fork 9 with the supporting washer 10 does not prevent the table from turning 5.

1After the end of lowering the I1 lift fork down the drive mechanism

6 performs the rotation of the table 5 by the amount of rotation angle between the cassettes so that in place of the empty cassette 13 becomes a cassette filled with a stack of blanks. After turning off the drive

7 lifting the stack of blanks 25. Then the work cycle repeats.
