Benefits of technology

The system described in this patent is designed to automatically handle and sort narrow-slit rolls. It uses an overhead gantry and a roll pressure plate to pick and place the rolls. The system can handle rolls of varying diameters and amounts of pressure. It is contained within a small overhead self-supporting steel structure and uses pneumatic controls for holding down the rolls. The system can sort rolls into different orders and can handle and sort rolls of different widths. It is designed to be customizable and can be tailored to different customer requirements. The system is safe and efficient, and it allows for easy handling and sorting of narrow-slit rolls.

Problems solved by technology

The narrow-slit rolls, given their narrow width are not capable of standing unassisted without risk of falling over.
Despite being narrow, the narrow-slit rolls can still weigh hundreds to thousands of pounds depending on the width.
This heaviness coupled with the unstable nature of narrow slit rolls outs users at high risk for injury.

Embodiment Construction

[0044]Referring now to FIGS. 1-17, a narrow-slit handler 1 is shown. The narrow-slit handler 1 comprises an overhead gantry 5, a cushioner 10 with stabilizer arms 11, hold-down 15, conveyors 25, kickers 20, narrow-slit storage 30, and upender 35.

[0045]A roll 3, which has been previously cut into slits of desired widths (narrow-slits 2), enters the narrow-slit handler at ramp 45. The cushioner 10 extends to meet roll 3 with a cushion 12 and at least two stabilizer arms 11. The cushioner 10, using the cushion 12 and stabilizer arms 1, guides roll 3 down ramp 45 and onto conveyor 25. Hold-down 15 centers itself on roll 3 and lowers hold-down arms 16 to make contact with roll 3 and hold the narrow-slits in position to prevent toppling. Overhead gantry 5 positions itself to the side of roll 3, selecting the desired number of narrow-slits 2, clamping the narrow-slits 2 into place and transports the narrow-slits to at least one narrow-slit storage 30 (FIG. 31). Narrow-slit storage 30 is sl...

Abstract

A system for automatic handling and sorting of narrow-slit rolls. Wherein the system is also capable of preventing toppling of the narrow-slit rolls.

Description

CROSS-REFERENCE[0001]The present patent application is based upon and claims the benefit of provisional patent No. 63 / 153,655, filed Feb. 25, 2021.BACKGROUND OF THE INVENTION[0002]When manufacturing paper products, large rolls of tissue paper are provided for processing into various products such as bath tissue, paper towels, air dried, and crepe air dried materials such as napkins. The rolls of tissue are provided on cores and may weigh up to 8,000 pounds. The tissue is rolled on the core and may be 90 inches in diameter. Paper manufacturers receive these rolls and unwind them to process the tissue paper into the various products being manufactured. Certain paper applications require strips of tissue paper narrower than the large rolls, known as narrow-slit rolls. These narrow-slit rolls can vary in thickness depending on the desired application. The narrow-slit rolls are cut from the large roll to a desired thickness. The narrow-slit rolls, given their narrow width are not capable...
