DESC:FIELD OF THE INVENTION
The present invention relates generally to conveyor system, more specifically a vertical conveying system and a method Made of Heavy-Duty Modular Belt for moving materials vertically across multi floors or levels.

BACKGROUND OF THE INVENTION
Conveyor systems are generally known in the art. Conveyors are used in multiple industries to move and transport material from one place to another. And their type depends on the nature of its use.

Warehouses & manufacturing industries are generally with mezzanine or multi floors for storing or processing of materials considering effective utilization of the available space through vertical expansions. Hence moving materials between multi floors are critical requirement in industries.

A conventional chain-based vertical conveyor system requires multiple sprockets and also the system get disconnected at times. Here, a modular heavy duty 3-dimensional belt disclosed on patent application 201841009356 has been configured vertically as conveying medium.

It would be advantageous to have a vertical conveyor system for moving materials such as bins/ totes, cartons, bags, etc across multiple floors for storing or further processing in warehouses & manufacturing industries, that will not get disconnected and drives on a single sprocket.

OBJECTS OF THE INVENTION
An object of the invention to provide a vertical conveying system.

It is another object of the invention to provide a conveying system made of heavy-duty modular belt sections and material carriers capable to transfer materials across multi floors or levels.

It is yet another object of the invention to provide a method to vertically transfer materials across multi floors or levels.

SUMMARY OF THE INVENTION
To meet the objects of the invention and overcome the drawbacks of the prior art it is disclosed here, a vertical conveyer system to transfer materials across multi floors or levels comprising: a plurality of modular heavy duty belt leaves with rollers on the lower side; a plurality of C profiles ; a plurality of holding arms with rollers and bearing blocks; and a plurality of material carriers; a driving means to drive the modular heavy duty belt leaves; Characterized in that the belt leaves are guided on one C profile, the holding arms attached to the belt leaves are guided on another C profile, and the material carriers with rollers are arranged to the holding arms through bearing blocks.

Further discloses a method to vertically transfer materials across multi floors or levels comprising steps of: loading materials on material carriers arranged on holding arms attached to modular heavy duty belt leaves; driving the belt leaves using a driving means; and dropping materials on opposite forks positioned at the retrieving positions; Characterized in that the belt leaves are guided on one C profile, the holding arms attached to the belt leaves are guided on another C profile, and the material carriers with rollers are arranged to the holding arms through bearing blocks.

DETAILED DESCRIPTION OF THE INVENTION
Referring to Fig 1 and Fig.2, this system is made of heavy-duty modular belt sections and material carriers capable to transfer materials vertically across multi floors or levels, wherein the modular heavy duty 3-dimensional belt has been configured vertically as conveying medium.

Referring to Fig.3 and Fig.4, rollers of the belt leaves (1) are guided on “C” profile (C1) for supporting vertical movement of the system. Modular belt leaves (1) are designed to drive simply with single sprocket (2). Due to solidity of the belt leaves (1), though the link opens, the system will not get disconnected and the solid surface of the belt provide flexibility to attach and carry application specific material carriers.

Referring to Fig.5 to Fig.8, modular heavy-duty belt leaf (1) consists of holding arms (3) at required intervals. Also, holding arm (3) is provided with set of rollers and guided on a separate “C” profile (C2) for stable movement with load. The arm is provided with a bearing block (4) for attaching material carrier (5). The material carriers (5) are attached to guiding arms (3) through the bearing block (4) and bearing block (4) retains the material carrier (5) in downward position at all the time. The carrier (5) is provided with a set of rollers and guided with individual profiles to avoid sway caused while placing or retrieving materials also while moving on 180-degree curved transitions.

Referring to Fig.9 to Fig.11, the carriers (5) are designed like a fork for automatic dropping of material on opposite fork (6) placed at retrieving positions on required floors / levels. The opposite fork (6) will also be provided with automatic movement for applications with multiple retrieving positions such as more than one floor or sorting applications. The vertical heavy-duty belt-based system is designed as a platform to scale vertically and horizontally for using in multiple applications such as Multi floor conveying, Vertical sorting, Storage system, etc.

Advantages
• Simple & scalable platform configurable for applications require vertical movement of material.
• Due to solidity of the heavy-duty belt leaves though the link opens, the system will not get disconnected like a conventional chain hence safer than chain-based systems.
• Solid surface of the belt provides flexibility to attach application specific material carries
• Modular belt leaves are designed to drive simply with single sprocket unlike conventional chain based systems which require multiple sprockets.
