SU1211190A1 - Device for lifting rolls in unwinding - Google Patents

Description

The invention relates to equipment for unwinding rolls and should be used in organizations with a limited amount of rough work on paper that is detachable from the roll.

The aim of the invention is to simplify the construction and facilitate maintenance.

Figure 1 shows the device, side view; figure 2 - the same, front view.

A device for lifting coils during unwinding comprises a pivoting frame 2 mounted on the basis, on the sides of which 3 there are arcuate recesses 4 for the trunnion pins 5 of the roll holder. The notches 4 are made with the displacement of the vertical and horizontal lines to facilitate the installation of rolls of 6 different diameters. The device also has two 11-frame frames, on the vertical posts 7 of which axis 8 of rotation of section 2 is placed. A drum 9 of the isotal connections is equipped with a drum 9 for na.viOTKK material from roll 6.

To rotate frame 2, there is an actuator made in the form of a screw jack, the body of which is pivotally connected to the jumper 11 between the sides of the ram 2, and the screw 12 is provided with a flywheel 13 and the means 14 of the angular rotation of the screw 12 relative to the base 1 .

To ensure the maneuverability of the device, the base 1 is equipped with wheels 15.

The device works as follows.

Since the main condition for unwinding a roll is to separate it from

five

the floor surface of the displacement, then the operator 6 pulls up, exerts a small effort, on the roll 6, which lies on the floor of the displacement, so that the base 1 of the frame is parallel and symmetrically located relative to the ends of the roll 6.

Under the trunnion 5, fixed at the ends of the roll holder axis, previously inserted into the axial channel of the roll and fixed in its holes with cones, the recess 4 ram 2, suitable for the diameter of the coil, is brought in, first the screw flywheel 13 and then pick it up. When the trunnions 5 are tightly pressed into the cavity, I rotate the flywheel 13 lightly and lift the roll so that a gap of 10-15 mm is formed under the standard sheet.

.iOH is preliminarily cleaned from a 1-CITY wrapper, the end of the paper tape is attached to one of the edges of the drum 9. Smooth the drum, winding a number of layers on it. In doing so, the roll turns freely on the pins 5 and the paper is rewound onto the drum.

Stop rotating the drum, cut off all the layers of the bu.magi along the edge, remove it from the drum and cut it with a guillotine. Then this cycle repeats.

The technical and economic effect of the proposed device is a significant reduction in manual labor, reducing the number of people to one person, drastically reducing paper losses and even eliminating them completely and reducing the required production space. .
