Description

one

The invention relates to the mechanization and automation of piece-by-piece delivery of blanks, for gripping by an industrial robot and feeding to the next technological operation, for example, in a press stamp, and can be used in sheet-and-extrusion production in automatic lines based on industrial robots submission of blanks to the press stamp and issuing them from the stamp.

A device for feeding workpieces from the foot to the treatment area, comprising a base, a rotary table mounted on a column, a table rotation drive, a drive for raising a stack of blanks in the form of a pneumatic cylinder with a stem, anchor washer and a lifting fork 1.is, is known.

Its disadvantage is that the drive for lifting the stack of blanks is located directly below the table, which reduces the effective capacity of the stack of blanks in height.

The purpose of the invention is to increase the capacity of the store.

The goal is achieved by the fact that in a device containing a base, a turntable mounted on a column.

table rotation drive, foot lifting drive of blanks in the form of a pneumatic cylinder with a rod, an washer and a lifting fork, the column is made hollow with a through groove along the generator, the foot lifting drive pneumatic cylinder is installed in the upper part of the column with the rod down, while the rod is placed inside the column and lifting the fork is console mounted on the rod and placed in the said slot, the rotary table is made with radial slits extending from the center of the table to its periphery to the foot of the blanks.

FIG. 1 shows the device (section A-A in FIG. 2); in fig. 2 shows a section BB in FIG. one; in fig. 3 shows a section B-B in FIG. one.

The magazine device comprises a base 1, on which a column 2 with an internal cavity 3 and a vertical slot 4 is installed. The column 2 serves as an axis of rotation of the table 5 by means of a rotation actuator 6, which is also mounted on the base 1. The drive 7 for lifting the stack 8 of the workpieces 9 with a stem 10 mounted on the column 2 above the turntable 5 with the rod 10 down, while the rod 10 passes inside the cavity

3 columns 2. The magazine device is equipped with a lifting fork 11, which is cantilever mounted on the rod 10 of the drive 7 for lifting the stack 8 of the workpieces 9 with support washer 12 fixed to the end, which can be moved in a vertical slot 4 made in column 2.

In the rotary table 5, according to the number of positions from its center to each foot 8 of the blanks 9, radial through-height grooves 13 are completed, ending with slots 14 having the configuration respectively the bearing washer 12. The initial position of the lifting fork 11 is below the rotary table 5, so that does not prevent its rotation in this position.

On the turntable 5, interchangeable cassettes 15 with pins 16 are mounted, between which a stack 8 of blanks 9 is laid. The housing 17 of each cassette 15 also has a slot 18 through height coinciding with the corresponding slots 13 and 14 of the turntable 5. The gripper 19 of an industrial robot is at the working position of taking the workpiece 9 from the magazine device and transferring it to the press stamp. Vertical slot 4 columns 2 is located on the side of the working position.

The store device works in the following way.

The turntable 5 has several positions. One of the positions is working, and the rest are used to load the replaceable empty cassettes 15 with blanks 9. At these positions it is possible to rearrange the pins 16 in accordance with the configuration and dimensions of the blanks 9. After the operator loads the cassettes 15 with blanks 9, the actuator 6 turns table 5. The table rotates. 5. During the rotation of the table 5, the stem 10 of the actuator 7 for raising the foot 8 of the workpieces 9 together with the lifting fork 11 and the supporting washer 12 are in their initial lowest position so that the lifting fork 11 with the supporting washer 12 do not interfere with the rotation of the table 5. After the termination of the rotation of the table 5, its radial slot 13 is aligned in the same plane with the vertical slot

4 columns 2, mounted on base 1, and the drive 7 for lifting the stack of blanks is turned on. Its rod 10 together with the lifting fork 11 and the bearing washer 12 rises. The rod 10 moves in the inner cavity 3 of the column 2. The lifting fork 11 moves in the vertical slot 4 of the column 2 and, together with the support band 12, passes through the radial slot 13 and the slot 14 of the turntable 5 and slot 18 in the housing 17 of the cassette 15. During movement of the lifting forks 11 turntable

5blocked from rotation and strictly fixed in a certain position. The support plate 12 during lifting rests on the lower workpiece of the foot 8 and the lift drive 7 raises the entire stack of workpieces by such amount until the upper foot workpiece reaches the level from which the upper workpiece is gripped by the industrial robot 19. After that, the lifting drive 7, together with the workpiece stack, stops at this level. The grip 19 takes the workpiece 9 on top of the foot 8 and moves to the press stamp.

After the grip 19 has removed the upper workpiece, the lift drive 7 is actuated upwards by an amount corresponding to the thickness of the removed workpiece, constantly maintaining the upper workpiece at a certain predetermined level. Thus, the drive 7 for raising the stack of workpieces works upward until the end of the workpiece entire workpiece ends. After that, when the cassette 15 is empty, the drive 7 for raising the stack of blanks is turned on in a downward motion. Its rod 10, together with the lifting fork 11 and the support plate 12, are lowered to the lowest position, so that the lifting fork 11 with the support washer 12 will not prevent the table from turning 5.

After the lowering of the fork 11 is lowered down, the drive mechanism 6 rotates the table 5 by the amount of rotation angle between the cassettes so that the cassette filled with the stack of blanks becomes replaced with the empty cassette 15. After the end of the rotation, the drive 7 for raising the stack of workpieces is turned on. Next, the work cycle repeats.

For convenience, the cassettes can be loaded not every time immediately after emptying one cassette, but after emptying several cassettes, but in such a way that it would not be necessary to stop the operation of the entire line to load the cassettes. Due to the fact that the drive for lifting the stack of blanks is taken out from under the turntable and mounted on a column under the turntable, the capacity of the magazine device is no less than doubled.
