SU1400734A1 - Arrangement for separating an upper sheet from a stack and piling sheets to a stack - Google Patents

Abstract

The invention relates to the field of cold metal forming and can be used to separate a sheet from a foot and to stack sheets in a foot. The aim of the invention is to increase the reliability of operation. The beams, located symmetrically to the axis of movement of the sheets, move one relative to the other by a distance equal to the width of the sheet, and the Traverse with suction cups descends and seizes the upper sheet from the foot, placed on the lifting table. Power cylinders mounted on the traverse move the pushers which turn the drive rollers hinged on the beams through the copiers. When lifting, the traverse of the sucker drops the sheet onto the drive rollers. The return to the initial position of the rollers is carried out by the action of its own weight. The rollers are also equipped with their rotation drive and rotation limiter, made in the form of power cylinders mounted on the beams, pillows moving along the vertical guides of the beams, and shock absorbers fixed on the pillows that can interact with the rollers. 3 il. with (L

Description

The invention relates to the cold working of metals by pressure and can be used to separate a sheet from a foot, as well as to stack sheets in a foot.

The purpose of the invention is to improve reliability.

Figure 1 shows a device for separating a top sheet from a foot and stacking sheets in a foot; figure 2 - section aa in figure 1; on fig.Z - type B on fig „2„

The device contains beams 1, mounted on both sides symmetrically with respect to the axis of movement of the sheets 2, guides 3 mounted on the base 4 perpendicular to the axis of movement of the sheets 2 ,. drives of movement of beams 1 along directions 3, made in the form of power cylinders 5, the mechanism of moving sheets 2 to the foot or from the foot, performed HefjHbrfi in the form of levers 6, fixed first by axes 7 on beams 1, shafts 8, mounted using bearing units 9 on levers 6, take-up rollers 0 mounted on shafts 8, drives 11 fixed on levers 6 and connected to shafts 8 via sleeves 12, stops to limit the turns of levers 6 around axes 7 —in the vertical plane, made in the form of power cylinders 13, mounted on beams 1, but of the hinges 14 pivotally connected to the power cylinders 13 and mounted in the vertical guides 15, shock absorbers 16 fixed on the sliders 14 with the possibility of interaction with the levers 6,

Under the bulkhead 1 there is a lifting table 17 for placing a stack of sheets. The table is fixed on vertical routes x 18 and is equipped with a drive: lifting, made in the form of a power cylinder padra 1 9.

A mechanism for separating the sheets from the foot is installed above the lifting table (to grip the sheets) (Designed as a power cylinder 20 having a piston 21 with a rod 22, the yoke 23 pivotally attached to the rod 22, Traverse 23 moves in the base 4 in the direction 1 1 m 24. On traverse 23

vacuum pick-up bodies 25 are mounted, guides 26 located perpendicularly to the bikes 1, pushers 27 fixed on the 0 Q direction

26, drives of movement of the pushers 27, made in the form of power L1INDROV 28. A stop 29 is mounted behind the beams 1. Copiers 30 are mounted on the levers 6.

The device works as follows.

The beams 1 are moved by Guide cylinders 5 by Guide cylinders 5 and the beams 1 are installed / poured one from the other at a distance equal to the width of the sheet 2.

The traverse 23 is lowered downwards and the gripping bodies 25 are gripped by the upper sheet 2. They include power cylinders 28, which move the pushers 27 towards the beams 1. The pushers 27 act on the copiers 30, which rotate the levers 6 around the axes 7. The rollers 10 are deflected upwards and do not prevent the sheet 2 from moving. The cross member 23 moves upwards. When exiting the interaction of the pushers 27 with the copiers 30, the levers 6 are rotated to their original position. zone about Work (not shown).

When stacking sheets 2 in the stack, the sheet moves along the rollers 10 up to the stop 29. The power cylinders 13 are turned on, which move the sliders 14 upwards in the direction of the lane 13. Shock absorbers 16 exit From the interaction with the levers

6, which rotate around the axes

7. Rollers 10 lowered sheet

2 falls onto table 17. Power cylinders 13 are turned on, which move the sliders 14 along guides 15 downwards. The shock absorbers 16 act on the levers 6 and turn them around the axes 7. The rollers 10 take the initial position.

The economic effect of using the invention in industry will be 435 thousand rubles.
