DESC:FIELD OF THE INVENTION
The instant invention relates to conveyors, particularly to a multi directional conveyor transfer system.

BACKGROUND OF THE INVENTION
Larger warehouses spread across multi-tires with intense flow of items/ SKUs in segments like Ecommerce, Retail, FMCG, etc. require multiple branch & main conveyor lines with automatic flow control & transfers such as merging, diversion/ sorting, etc., to meet high throughput requirements & increasing performance demands of the warehouse.

The conventional wheel-based systems principally made with omni wheels help move the entire system instead of the items/SKUs which always require dual wheels with offsets, hence overall system becomes complex. Built with many numbers of components increases unnecessary maintenance points & failure possibilities also adds unnecessary cost.

The conventional belt-based systems require applying of external forces using any external mechanism or motorized belts to control the flow of item/SKUs. Having typical changes of a conventional modular belt technology such as requiring sliding structures/ UHMPW etc., for the longer belt sections. Many varieties of application specific belts, system built with more components adds challenges in engineering, maintenance and more failure possibilities also add unnecessary cost.
US11365058B2 discloses a spiral conveyor system which includes a drum and a conveyor belt travelling helically about the drum from an entrance end to an exit end of the drum, and a rib associated with the drum, wherein the rib extends radially from a surface of the drum. Thus, it uses complex combination of components for transfer the conveying items to a different track.

JP6987431B2 discloses a wheel type direction changer used in a conveyor line for changing the direction of movement of the conveying items, wherein the controllability of the wheels for changing the direction is not discussed.

CN103224134A discloses a bidirectional distribution device for sorting box-type goods in logistics comprising a base and plurality of distributor units, wherein a steering wheel, a rotary seat, a fixed seat and a round belt are arranged on each distributor unit; the said steering wheel are driven by power wheels and a gear mechanism is engaged for changing the direction of the distributor units. Thus, it involves a complex mechanism of gears, belts, wheels, etc.

Therefore, there is a need for a transfer system which is capable of conveying the items in the conveying system in multi direction with a simple and effective construction.

OBJECTS OF THE INVENTION
An object of the invention to provide a multi directional conveyor transfer system for controlling flow of item/ SKUs in branch/ main conveying limes.

SUMMARY OF THE INVENTION
To meet the objects of the invention it is disclosed here multi directional conveyor transfer system for controlling flow of item/SKUs in branch/ main conveying lines for the purpose of transferring between conveyors placed at 90, 180 deg and any angular direction; merging inputs from multiple conveyors; diversion/sorting from one conveyor to another conveyor to another conveyor or to multiple positions; aligning/ turning/ orienting etc.,

The multi directional transfer system constructed with series of conveying and transvers modules made of multi directional conveying wheels and mounted perpendicular to each other for conveying as well as controlling flow of items/SKUs towards any required direction/ position by operating the rollers at different speeds & directions. Differential wheels and small rollers around the top circular surface of the conveying & transvers roller modules aid controlling the movement of the items/SKUs towards desired direction/ position.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG.3, a multi directional transfer system (100) is disclosed which is made of two types of roller modules with multi directional wheels (4) and termed as conveying (1) and transvers roller modules (2). Many multi directional wheels placed on free rotating shaft (5) mounted through bearing joints to set of fixing components (6) at both the ends, forms a multi directional roller module. Roller modules are fastened to the system structure through the fixing components. The multi directional wheels of the roller modules are provided with small rollers around the top circular surface to aid transvers movement of items/SKUs.

Conveying and transvers roller modules are made of wheels with two different dimensions one as smaller and the other as bigger to offset the shafts of both sets for mounting perpendicularly to each other without colliding. Multiple conveying roller modules are serially connected using belts/ chains and connected to a motor. Similarly, the serially connected transvers modules are connected to another motor. Both conveying and transverse motors are independently controlled for speed and direction to aid movement of items/ SKUs towards desired direction or position.

Various flow control requirement in conveying automation is easily possible with multi directional transfer system by operating the conveying and transverse roller modules at different speeds and directions, which aid controlling the flow of items/ SKUs to move towards desired direction/ position also with desired orientation & speed. Few application possibilities in conveying automation are listed below and not limited to conveyer transfer- Any angle, merging from multiple conveyor lines, diversion/sorting- to any angle, aligning/turning/orienting, etc.

Advantages
• Multi directional transfer system consists of a simple construction with modular rollers made of multi directional conveying wheels.

• Modular and scalable as per application requirements.

• Flow control achieved with simple multi directional differential wheels and does not require any external mechanism/ motorized belt.

• Not required to have many applications specific varieties unlike conventional belt-based solutions.

• Simple system made of minimal components reduces overall complexities, maintenance, wears, failure points and the cost.
