LONG ROLL OFF-LOAD ASSIST
Publication Date: 2003-Sep-12
The IP.com Prior Art Database
An apparatus for assisting an operator to off-load a finished roll of web from a rewind spindle permits the operator to off-load the finished roll from the rewind spindle in a more efficient and safe manner for subsequent processing. After the finished roll of web is off-loaded, the apparatus then rotates the roll from a vertical position to a horizontal position, placing the finished roll on the next working station (such as wrapping and packing).
LONG ROLL OFF-LOAD ASSIST
A device for assisting the operator to off-load a finished roll from a rewind spindle (such as a perforator or spooler) so that the operator does not have to endure the weight of the roll that is being off-loaded.
Manually handling rolls of 3000 feet length and greater is an ergonomic and safety concern (weight of 5 pounds per 1000 feet length). To address this problem there are many systems ranging from a manual vacuum hoist on a monorail to a fully automatic robot.
A manual vacuum hoist on a monorail is cumbersome and hard to operate and does not have precise location control to protect the roll while being handled. Furthermore, not knowing where the roll is at all times in a dark room environment can present a safety concern.
A fully automatic robot is a high cost alternative. In addition, cycle time may be greatly affected (increased) due to system safeguard requirements since the operator has to work in close proximity to the robot.
The Long Roll Off-Load Assist is a semi-automatic device that will allow the operator to off-load a finished roll from a rewind spindle and hold onto the roll while the operator starts the next winding cycle. In this way, cycle time can be improved since the operator does not have to waste time handling the finished roll. The device will then rotate the roll from a vertical position to a horizontal position, placing the finished roll on the next working station (such as wrapping and packing).
In the disclosure, the device, finished roll, and a rewind spindle are shown in FIGS. 1 and 2 as top view and front view, respectively.
A typical process for off-loading a roll without the Off-load Assist Device is as follows:
1. The operator manually removes the roll from the rewind spindle.
2. The operator carries it to and places it down on a wrapping/packing table.
3. The operator comes back to the machine to start the next winding cycle.
4. The operator goes back to the wrapping table to finish wrapping the roll.
A typical process for off-loading a roll using the Off-load Assist Device:
1. The operator uses the Off-load Assist Device to engage the roll at the rewind spindle and then swings the roll away from the machine toward the wrapping table.
2. While the roll is hung on the Off-load Assist Device, the operator starts the next winding cycle.
3. The operator swings the Off-load Assist Device to the wrapping table and finishes wrapping the roll.
