ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to the collection, volume reduction, and transportation of scrap tires.
2. Background
Conventionally, scrap tire recyclers haul a tire collection trailer to a scrap tire collection site and park it there for so long as it takes for scrap tires to accumulate in an amount sufficient to fill the trailer with tires. A tractor is needed to haul the tire collection trailer from the scrap tire collection facility, to haul on to the customer, and then to haul the trailer from that location to another location and back to the recycling facility.
INTRODUCTION TO THE INVENTION
Scrap tire recyclers typically park a tire collection trailer at the scrap tire collection site, usually until it is full, and a tractor is needed then to come along and haul the trailer from that location to another location for further processing. For each tractor and trailer, expensive costs are involved, e.g., such as insurance, license, equipment ownership (capital), depreciation, maintenance, operating expenses, and primarily the transportation cost associated with the limited weight or volume of tires which can be placed on a conventional trailer/container.
The full trailer, having 1,000 to 1,250 tires loaded in the trailer, must be taken back to a Recycling Facility and/or Home Base. Only about 1,000 to 1,250 scrap tires can be hauled in the trailer loose, i.e., loosely assembled in the trailer.
For each tractor and trailer, expensive costs are involved, e.g., such as insurance, license, equipment ownership (capital), depreciation, maintenance, operating expenses, and primarily the transportation cost associated with the limited weight or volume of tires which can be placed on a conventional trailer/container.
For efficiency and in order to justify the transportation cost associated with scrap tires, it is important to reduce these costs, which are critical to achieve a break even operation in the scrap tire recycling industry.
Once at the Processing Center/Facility which is equipped with loading/unloading docks, the trailer is unloaded. Unloading is accomplished via a machine in an area where the trailer can unload to a loading dock platform with a skid loader to extract the tires from the trailer. Otherwise, the trailer must be unloaded by hand. The unloading thereby is identified as another transportation cost.
In the conventional operation, a tractor delivers an empty trailer to the customer's location and returns a full trailer, thus, requiring two trips. For every customer, the conventional operation requires two trailers and four trips by the tractor. The tractor drops a second trailer off empty and then takes the first trailer back full on the same round trip, so as not to require the tractor and driver to wait for the amount of tires to collect at that center to fill the trailer. Thereby, two trailers are needed in the conventional operation.
Moreover, for every customer, the conventional operation requires two trailers which are entirely road-worthy. So the conventional operation requires insurance, license, equipment ownership (capital), depreciation, maintenance, and operating expenses for two road-worthy trailers.
The scrap tire collector then provides for the processing of the tires at the processing center. The scrap tire collector runs the tires through a shredder or chipper or other means of processing.
It is an object of the present invention to provide a novel scrap tire collection process.
It is an object of the present invention to provide a novel scrap tire collection process to reduce transportation costs in the collection and distribution of scrap tires.
It is an object of the present invention to provide a novel scrap tire collection process to reduce equipment capital and maintenance costs in the collection and distribution of scrap tires.
Yet another object of this invention is to provide a novel scrap tire collection process to reduce manpower and labor costs in the collection and distribution of scrap tires.
A further object of this invention is to provide a novel scrap tire collection process which obtains one or more of the objects and advantages set forth above.
A further object of this invention is to provide a novel scrap tire collection process which eliminates or reduces the problems associated with conventional scrap tire collection methods.
These and other objects of the present invention will become apparent to those skilled in the art from a careful review of the detailed description which follows.
SUMMARY OF THE INVENTION
The present invention provides a method of handling scrap tires including a satellite tire collection enclosure, in one aspect constructed of baled tires, sized to receive at least about 2400 scrap tires, collecting scrap tires inside the tire collection enclosure until the enclosure is at or near capacity, volume reducing the scrap tires by baling the scrap tires using a mobile tire baler having a baler and a boom on a mobile platform at a minimum of about 2,400 whole tires into about 24 bales, and transporting baled scrap tires to a home base, a recycling center, or directly to an end-user. In one aspect, a mobile tire baler includes a baler and a boom on a mobile platform, a cutter for over-size tires, and a crusher for tire rims.
