HOPPER FOR CONTINU~USLY AND AUTOMATICALLY
DRAWING OUT TIRES __ _ BACKGROUND OF THE INVENTION
The present invention relates generally to a hopper for continuously and automatically drawing out tires and feeding them and, more particularly, to a hopper which can continuously and quantitatively supply waste rubber tires to a thermal-decomposing furnace or a chipper for reusing the tires as fuel and the like.
DESCRIPTION OF THE PRIOR ART
With the recent remarkable increase in the amount of generation of waste rubber tires resulting from the rapid development of the automotive industry, the regeneration and appropriate treatment of these waste tires become more and more a great social problem from the viewpoints of resource saving, energy saving and preservation of the environment.
With these social needs, researches of regeneration of the waste tires and their industrialization have become more and more active and apparatus for thermal-decomposing waste rubber tires has been developed.
`` ~3 1 ~
In the case where the tires are treated in large quantities in a large sized tire thermal-decomposing furnace or chipper, the conventional, lahorious handworking process is very disadvantageous from the viewpoints of cost and continuous and quantitative feed.
SUMMARY OF THE INVENTION
According to one aspect of the present invention, there is provided a hopper for continuously drawing out randomly oriented tires, each having a central opening and being formed of tread, from a port, comprising one or more lines of declining roller conveyors disposed under a port for charging the randomly oriented tires; and inclined conveyor means extending upwardly from under the lower end of the roller conveyors for receiving the charged tires from the roller conveyors, said conveyor means including a plurality of hooks spaced apart in a direction longitudinally of said conveyor means and projecting from said conveyor means for engaging the central opening of a tire to thereby move the tire along with the said conveyor means from a start position at the lower end of said roller conveyors to a position remote C
~2A~
from the start position where it is released to continuously and quantitatively feed the tires to a succeeding apparatus for treating them.
In a preferred embodiment according to the invention, the hopper further includes one or more means for thrusting up the tires to promote the slip down of the tires on the roller conveyors and the transfer of the tires from the roller conveyors to the chain conveyors.
The randomly accumulated tires which were thrown into the charging port with a shovel and the like spontaneously slip down the declining roller conveyors .
~ t~ 5 having a predetermined angle of downward inclination, for example, ranging from 15 to 75, preferably about 30.
The slip down of the tires on the roller conveyors and the transfer of the tires from the roller conveyors to the chain conveyors can be promoted by the means for thrusting up the tires which are provided under the roller conveyors. Each of such tire thrusting up means intermittently pushes up each of the tires through the space between two adjacent rollers of the roller conveyor.
During operation of the chain conveyors, each tire is caught on a respective hook provided on the chain conveyors and it is transferred to a predetermined place where it is released to continuously and quantitatively feed the tires to a succeeding apparatus for treating them.
BRIEF DESCRIPTION OF THE DRAWINGS
A specific embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings in which:
Figure 1 is a schematic side view of a preferred embodiment of a hopper for continuously drawing out and quantitatively feeding tires; and Figure 2 is a plan view of the hopper shown in Figure 1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE
INVENTION
Referring to the drawings, in which like numerals indicate like elements throughout the several views, Figure 1 shows a schematic side view of a hopper for continuously drawing out waste rubber tires and quantitatively feeding them.
The tires 10 are thrown into a housing of the hopper through a charging port 1 with a tire shovel ~not shown) and the like. Underneath the charging port 1 is disposed three lines of roller conveyors 2 each having a predetermined angle of downward inclination, for example, ranging from 15 to 75 and preferably about 30. Numeral 3 represents at least one means for thrusting up the tires which were provided under the roller conveyors 2. Each of these tire thrusting up means 3 can promote the slip down of the tires on the roller conveyors 2 and the transfer of the tires from the roller conveyors 2 to the chain conveyors described hereinafter by intermittently pushing up each of the tires through the space between two adjacent rollers of the respective line of roller conveyor.
~ 3 ~
Numeral 4 represents a plurality of lines of chain conveyors each having a number of hooks 13 arranged on the line at a predetermined equal space for catching the tires and transporting them to a given place. This chain conveyor 4 has a predetermined angle of upward inclination, for example, ranging from +30 to +80, and preferably, about +45. The setting angle of each hook to the chain conveyors 4 is determined depending upon the inclination angle of the chain conveyors 4. The amount of drawing out the tires and feeding them depends upon the width of the roller conveyors 2, the line numbers of the chain conveyors 4, the numbers of rotations thereof, the numbers of the hooks 13, etc.
In the case where the line numbers of the chain conveyors 4 are reduced for limiting a supply position of the tires and for controlling a supply amount of them, side guide rollers 6 and an apparatus for pushing the tires in a lateral direction such as a fluid cylinder 5 and the like may be provided in the side thereof.
In an example of feeding waste rubber tires to a thermal-decomposing furnace using the above-described hopper for continuously drawing out the tires, this hopper could draw out 400 tires/hour by using a roller conveyor 2 having about 3 meters width and a downward slope of about 30, and a chain conveyor 13t~
4 having an upward slope of ~5 and having hooks 13 having a pitch of 1 meter, 12 cm length and a setting angle of so. This work corresponds to that of four workers in a conventional handworking process.
The embodiments described should be taken as illustrative only and not as limiting the scope of the invention as defined in accordance with the accompanying claims.
