Document Type and Number:
Japanese Patent JP2017052609
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To make it possible to apply brake force from a regeneration brake to both support shafts by using a single electric motor and thereby to reduce cost, in a roll body support device for rotationally supporting a roll body c where a belt-like object is wound around a core tube b via a pair of support shafts 7, 7 to be connected to one and the other ends of the core tube.SOLUTION: The roll body support device includes: a pair of first oil hydraulic motors 8, 8 each connected to both support shafts 7, 7; a second oil hydraulic motor 10 connected to both of the first oil hydraulic motors 8, 8 via hydraulic pipes 9, 9 and rotates interlocked with rotations of both of the first oil hydraulic motors 8, 8 following a drawing of a belt-like object; and an electric motor 11 to be connected to the second oil hydraulic motor 10. It is so configurated that brake force is applied to both of the support shafts 7, 7 by a regeneration brake in the electric motor 11.SELECTED DRAWING: Figure 2
