Abstract

A system and method for tracking, storing, and distributing inventory of welding-type consumables within an industrial facility includes conveyors for moving and storing welding-type consumables on pallets or other shipment units to the proper work zones. Various sensors or detectors are employed at the loading and unloading ends of the conveyors to provide data for determining quantity, type, and/or location information for monitoring inventory or even automated reordering. Therefore, such a system and method provides robust, reliable, and inexpensive inventory management that can be adaptable and compatible with multiple brands, types, and shipment varieties of inventory materials.

Claims

1. An inventory management system comprising:

a conveyor configured to store and move welding inventory units to at least one work zone;

a reader positioned at a first end of the conveyor to read type information of each welding inventory unit loaded onto the conveyor;

an inventory unit sensor arranged to detect welding inventory units on the conveyor;

an inventory subunit sensor positioned at a second end of the conveyor to detect a number of welding inventory subunits within a welding inventory unit;

an information center connected to receive data from the reader, the inventory unit sensor, and the inventory subunit sensor; and

wherein one of the reader and the information center is programmed to determine whether each welding inventory unit loaded onto the conveyor corresponds to a welding process being performed in the at least one work zone.

2. The inventory management system of claim 1 wherein the inventory unit sensor and the inventory subunit sensor each comprise at least one of a weight sensor, an optical sensor, and a mechanical sensor.

3. The inventory management system of claim 1 wherein the type information is stored on welding inventory units and the reader is positioned to read the type information wirelessly therefrom.

4. The inventory management system of claim 1 wherein welding inventory units corresponding to welding processes of the work zone are one of predetermined by a user or automatically selected.

5. The inventory management system of claim 4 further comprising a warning unit to alert operators when a welding inventory unit not corresponding to a welding process of the at least one work zone is loaded on the conveyor.

6. The inventory management system of claim 1 wherein the information center is configured to monitor an inventory count for welding consumable inventory types from the received data.

7. The inventory management system of claim 6 wherein the information center is further configured to generate a reorder request when the inventory count reaches a threshold value.

8. An apparatus for maintaining welding consumable inventory comprising:

at least one storage surface having a loading end in a receiving area and an unloading end in a work zone;

the loading end configured to receive welding consumable shipment units and scan information therefrom;

the unloading end configured to detect a remaining number of subunits of a welding consumable shipment unit; and

at least one processing unit configured to;

determine whether welding consumable shipment units loaded onto the at least one storage surface are of a type to be used in the work zone;

manage a queue of welding consumable shipment units loaded onto the at least one storage surface; and

calculate at least one inventory amount thereof.

9. The apparatus of claim 8 wherein the at least one storage surface is configured for unloading in a single-file order.

10. The apparatus of claim 8 wherein the at least one processing unit is further configured to generate a replenish order when the at least one inventory amount is reduced to a threshold value.

11. The apparatus of claim 8 further comprising a detector positioned between the loading end and the unloading end to monitor welding consumable shipment units on the at least one storage surface.

12. The apparatus of claim 8 wherein the loading end of the at least one storage surface further comprises a shipment unit sensor and the unloading end of the at least one storage surface further comprises a shipment subunit sensor.

13. The apparatus of claim 8 wherein the loading end of the at least one storage surface is further configured to alert an operator when a welding consumable shipment unit is loaded thereon, which is not of a type to be used in the work zone.

14. A method for implementing an automated welding inventory system comprising the steps of:

delivering at least a first type and a second type of welding consumable bulk shipments to a welding facility;

loading the first type of wielding consumable bulk shipment onto a first conveyor, and loading the second type of welding consumable bulk shipment onto a second conveyor;

monitoring a quantity of each bulk shipment type on the respective conveyor;

maintaining at least one current inventory count by type of welding consumable, based upon the quantity and type of bulk shipments monitored;

generating an order request for additional welding consumable bulk shipments when the at least one inventory count reaches a threshold amount; and

delivering a new shipment of welding consumable bulk shipments.

15. The method of claim 14 further comprising the step of outfitting at least one conveyor to convey bulk shipments in a first-in, first-out order.

16. The method of claim 14 wherein the step of monitoring bulk shipment quantity further includes at least one of receiving characteristic information for each bulk shipment, monitoring a number and position of bulk shipments on a conveyor, or monitoring a number of remaining packages of a bulk shipment.

17. The method of claim 14 further comprising the step of causing only one type of bulk shipment to be loaded onto a conveyor.

18. The method of claim 17 further comprising at least one of configuring the conveyor to reject bulk shipments of an incorrect type or causing a removal request to be issued for bulk shipments of an incorrect type.

19. The method of claim 15 further comprising calculating the inventory threshold amount in consideration of a rate of use of at least one inventory type.

20. The method of claim 15 further comprising causing the at least one current inventory count to be automatically transmitted to an inventory vendor.

21. An inventory monitoring system comprising:

at least one inventory storage track having first and second ends;

an identification scanner positioned at the first end of the at least one inventory storage track and configured to scan identifying information from welding inventory units loaded onto the at least one inventory storage track;

an inventory unit detector positioned between the first and second ends of the at least one inventory storage track and configured to detect a number and a relative position of welding inventory units on the at least one inventory storage track; and

a processor connected to receive data from the identification scanner and the inventory unit detector and programmed to continuously monitor a location of each welding inventory unit therefrom.
