Problems solved by technology

In this case, the operation for switching the unwinding equipment, i.e. switching from a single roll unwinding mode to a simultaneous unwinding of two rolls, is time-consuming and complicated
Since the unwinding device is usually double and the configuration of the arms should be the same on both sides, i.e. usually two rolls are unwound on both sides of the unwinding device or a single roll is unwound on both sides of the unwinding device, Hence the increased complexity of these operations

Abstract

The invention relates to a device (1) comprising at least one pair of arms (15, 17) for lifting a coil (B) which is to be unrolled. The two arms are in torsion connection by means of a rotating shaft (13), whose rotation about its own axis (AA). Between the two arms (15, 17), a central arm (35) is arranged and is connected to the rotating shaft (13) by means of a mechanism to rotate along with the rotating shaft, or is connected to the rotating shaft to enable the central arm to be connected to a fixing structure of a device by means of a hinge and is connected to the rotating shaft, and in such a position, the central arm does not interfere with the coil carried by the two arms (15, 17).

Description

technical field [0001] The invention relates to an unwinding device for unwinding a roll of sheet material, such as a cardboard roll used in a corrugated board production line. Background technique [0002] In many industrial fields, it is necessary to unwind sheet rolls that are fed to production lines. Typically, the paper roll is unwound for feeding to a corrugating line, wherein two or more paper rolls are joined together, at least one of them which is disposed between two liners having been pre-corrugated. [0003] DE-A-102010008906 and US2012 / 0085483 describe corrugated cardboard lines which utilize multiple unwinding devices for unwinding paper rolls. [0004] EP-A-968945 discloses an unwinding device for this application. Known unwinding devices generally comprise at least one pair of arms rotating about a horizontal axis. Each arm has a roll engaging element. The roll rests on the ground and is picked up by the arm's tail carriage which lifts the roll from the g...
