The present invention relates generally to a system for storing and managing the cores of rolls of sheet form material. After the sheet form material is unwound from the core, the core is transferred to the core storage and management system for further processing. The present invention is related to our co-pending application Ser. No. 12/928,231 for an Automatic Core Cleaning Apparatus and co-pending application Ser. No. 12/925,084 for an Automatic Core Joining and Cutting Apparatus. The present invention may be used independently of or variously in combination with the technology disclosed and claimed in the related applications. The co-pending applications are incorporated herein by reference.
The present invention is a highly adaptable core storage and management system that can be adapted for use in any industrial setting where sheet form material is provided on large rolls having cores. After the sheet form material is dispensed from the rolls during the manufacturing process, the core remains, usually having some remnants of sheet form material still attached. The core is cleaned, inspected and either stored for reuse, repaired and stored for reuse, or disposed of. The core storage and management system of the present invention is intended to accumulate the spent cores, clean cores, and rejected cores for either reuse or disposal. The core storage and management system will monitor the lengths and diameters of the cores and sort the cores of various sizes into storage racks designated for each core of various sizes. The storage and management system of the present invention can be designed for use in conjunction with a core cutting and joining apparatus such as that disclosed in our co-pending U.S. patent application Ser. No. 12/925,084. The core storage and management system of this invention can also be used in combination with a core cleaning apparatus as disclosed in our co-pending U.S. patent application Ser. No. 12/928,231.
Ideally, the core storage and management system of the present invention will identify clean cores of various sizes and diameters and store the clean cores in specified racks.
The core storage and management system is extremely adaptable in that it can utilize any number of storage racks and the storage racks can be adaptable to contain stacks of individual cores or cores of various lengths and diameters.
Cameras can be used to inspect incoming cores to see if they are clean or damaged. The core storage and management system of this invention includes an inspection station for the manual inspection of cores for damage. Any damaged cores can either be sent to a core cutter and joiner machine located proximate the core storage and management system, or disposed of if damaged too badly for repair.
The core storage and management system uses sensor arrays to monitor the length and diameter of each core member it receives. The core storage and management system maintains a record of the total number of each core size received and interfaces with the manufacturing processes to ensure that cores of proper diameter and length are being delivered to the proper cleaning and repair stages within the facility.
RFID tags are affixed to each core except for those damaged too badly for repair. The RFID tags contain information regarding the size and condition of each core (i.e. whether acceptable for re-use as is, in need of cleaning, in need of repair), and storage location.
The core storage and management system is used at facilities that convert product on cores and provides for reuse of the cores. The core storage and management system stores cores, identifies core lengths and diameters, identifies cores that are damaged and can be salvaged via a core cutting and joining apparatus, manages inventory, processes outbound orders by either utilizing existing inventory or creating the cores via the core cutter and joiner apparatus. The core storage and management system significantly reduces manpower and safety issues.
Other objects and advantages of the present invention will become apparent to those skilled in the art upon a review of the following detailed description of the preferred embodiments and the accompanying drawings.
The core storage unit section of the management system of the present invention is shown in
Referring now to
The inspection station includes at least one camera 41 positioned to inspect the core C. The camera 41 is preferably movable such that it can inspect both ends of the core C. In other embodiments, a second camera 42 may be included at the inspection station 30. If the core C is clean, it is delivered to a second cross conveyor 53 for return to the core storage unit section 20. An overhead crane 46 picks up the clean core and transports it to its proper rack 10 for storage. If the core C fails inspection, it is sent to a manual inspection station 44 for operator intervention.
Adjacent to and parallel with the loading conveyor 45 is an unloading conveyor 56. The loading conveyor 45 and unloading conveyor 56 are mounted on mechanism which is moveable longitudinally. Such longitudinal movement moves the two conveyor 45, 56 from a first longitudinal position at which the loading conveyor 45 is aligned with the first cross conveyor 52 for delivery of cores C thereto to a second position at which the unloading conveyor 56 is aligned with the first cross conveyor 52 so that it can receive cores C being removed from the core management system. However, the position and layout of the various units of the core storage management system 10 (i.e. core storage unit section 20, racks 10, core cleaning assembly 43, inspection station 30 and conveyors) may vary. Accordingly, the method of moving the cores may vary from site to site.
The storage racks 10 can variously contain individual used and clean cores. The clean cores C can be retrieved from the appropriate storage racks 10 for delivery to the unloading conveyor 56.
The core storage and management system further includes an inspection station 44 wherein each core can be delivered for manual inspection. If any of the cores are damaged, but salvageable, they can be delivered by crane 46 to the adjacent core cutter and joiner apparatus 47. A properly joined core can then delivered by overhead crane 46 to its appropriate storage rack 10.
It should be noted that the layout of the various components is not necessarily as shown in
This description of the core storage and management system is intended to be illustrative. As explained herein the system is extremely adaptable for use in a variety of manufacturing settings. The scope of the present invention is set forth in the appended claims.
This application is based upon and claims the benefit of U.S. Provisional Patent Application No. 61/460,826 filed Jan. 7, 2011.
