Description

Carrier with roll reversing mechanism

The present invention relates to a transport vehicle provided with a roll reversing mechanism having a simple structure in which an operator can safely reverse and transport a roll by himself / herself.

When storing a roll-shaped object, if the central axis of the roll-shaped object is placed in a horizontal state, it will roll and become unstable. For this reason, it is common to place the roll-shaped object upright so that the central axis is vertical. When a roll-shaped object stored vertically in this way is transported and set in a machine, the roll-shaped object is placed on a roll carrier in a state of being laid down sideways and moved. However, this work is difficult to handle due to the heavy roll-like material, and the worker may hurt his / her back. Further, even when lifting with a forklift or the like, it is necessary to lay the roll-shaped object that is stored vertically upright.
In order to safely perform the above work, as a conventional roll reversing device, a combination of a balancer and a hydraulic reversing machine, a bogie type reversing machine, and the like are considered. However, in the conventional way of thinking, there is a problem that the device itself becomes large-scale and the cost increases.

As prior art related to roll reversal, for example, the invention "roll-shaped material reversal lift" described in JP-A-9-255274 (Patent Document 1) and the invention "Put" described in JP-A-2006-232548 (Patent Document 2). The invention "lifter" and the invention "core for lifter and film roll" described in JP-A-2009-84016 (Patent Document 3) are disclosed.

On the other hand, the applicant of the present application has obtained a patent right for the invention "transport vehicle equipped with a roll reversing mechanism" having a simple structure in which a worker can safely reverse and transport a roll by himself (Patent Document 4, Patent Document 4, Patent No. 6066248)
