(54) DEVICE FOR PACKAGING ROLLS WITH METAL TAPE

one

The invention relates to rolling equipment and can be used mainly in the workshops where the rolling of the winding belt into coils is carried out.

A device for packing rolls with a metal tape is known, comprising a roll conveyor, centering rollers with electric drives and a chain for turning them on, and a mechanism for wrapping the rolls. In order to improve the quality of the packaging, the device has a smoothing roller 1.

The disadvantage of such a device is that the pro-roll roller does not provide for the interconnection of the turns of the packaging tape, which causes a displacement of the turns when transporting the packed rolls and reduces the quality of the packaging.

The purpose of the invention is to improve the quality of packaging by interconnecting the turns of the packaging metal tape.

This goal is achieved in that in a device for packing rolls with metal tape containing a conveyor for rolls, centering rollers with electric drives, a mechanism for wrapping rolls and a screed roller, the latter is located at an angle of 5 ° -30 ° to the wrapping mechanism, and. It has a metal working surface, while a welding transformer is installed in the device, the output ends of which are connected respectively to the ironing roller and centering rollers, and to the input ends of the welding transformer Ator connected electric centering rollers.

10 FIG. 1 shows a device for

packaging rolls with metal tape, top view; in fig. 2 - the same section. The device consists of a conveyor 1 for supplying rolls, centering rollers 2 driven by electric motors 3, a mechanism 15 of the bottom 4 for wrapping rolls and an electrode 5 made in the form of a smoothing roller with a metal working surface. The electrode 5 is equipped with a movement mechanism 6 and is pressed against the end face of the roll 7. The movement mechanism 6 and pressure of the electrode 5 is made in the form of a pneumatic cylinder.

The device is equipped with a welding transformer 8 (Fig. 1), the output winding 9 of which is connected at one end to electrode 5 and the other to centering rollers 2. Chain 10 of turning on motors 3 centering rollers 2 is aligned with circuit 11 of turning on welding transformer 8. The device uses Packing metal tape 12. A portion of the roll in FIG. 1 is shown wrapped with metal tape 12.

The device works as follows.

The conveyor 1 roll 7 (Fig. 1) is fed in a horizontal position to the centering rollers 2 (Figs. 1 and 2). The centering rollers 2 are driven by electric motors 3 and rotate the roll 7 in the direction indicated by the arrow.

At the approach of a roll 7 portion packed with a metal tape 12, pressure 5 is supplied to the pneumatic cylinder of the displacement mechanism 6 and pressing electrode 5. At this, electrode 5 (in the form of a roller) fits and presses against the end of the roll 7. Since the welding transformer 8 turns on with the rotation of the centering rollers 2, the pressing of the electrode 5 ensures the welding of the packing metal tape 12 in places where its turns overlap each other. In this case, the magnitude of the welding current is selected in such a way as to ensure reliable welding of the turns of the packaging metal tape 12 and prevent welding of the turns of the packaging metal tape to the roll 7.

The received angles between the axis of the electrode and the axis of the mechanism for wrapping the rolls are based on the following.

A decrease in the angle of less than 5 ° causes the electrode to shift into the zone of operation of the roll-wrapping mechanism. Increasing the angle more than 30 ° is also impractical, so

As after finishing wrapping the roll with metal tape, additional time is required to weld the wraps of the packaging metal tape to the parts of the roll from the wrapper to the electrode, which reduces the productivity of the device.

Due to the displacement of the coils and the destruction of the packaging during the transportation of the coils and during their storage, up to 1% of the metal products is transferred into a marriage as a result of corrosion and mechanical damage to the metal surface.
