It can be supplied to the vertical transfer conveyor one by one.

(Embodiment) Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. In the drawings, the waste tire supply device of this embodiment is roughly divided into a hopper 1 for randomly storing waste tires and a hopper 1 from the hopper 1. Conveyor 2 that receives the waste tires of the vehicle and conveys them in a substantially horizontal state
And a vertical transfer conveyor 3 that receives waste tires from the transfer conveyor 2, transfers the waste tires upward, and supplies them to the combustion furnace (not shown) side. It should be noted that the hopper 1 accommodates relatively small waste tires Ta used for light vehicles and ordinary vehicles and relatively large waste tires Tb used for buses and trucks. The waste tire supplied to the side (not shown) is intended for a relatively small waste tire Ta.

The hopper 1 is composed of a pair of side walls 4 and 5 facing each other and adjusting belts 6 and 6 which face each other between the side walls 4 and 5 in an inverted V shape to form a pair of side walls. It is formed into a rectangular funnel shape that is open to form a rectangular input port 7 and is open to a lower part to form a discharge port 8. The support frame 9 makes the discharge port 8 have a predetermined height with respect to the installation surface. It is installed in a floating state. The adjusting belts 6 and 6 are formed in an endless shape, and are rotatably mounted on the upper portions of the side walls 4 and 5, similarly to the driving roller 10 which is rotatably mounted on the lower portions of the side walls 4 and 5. It is also hung over the driven roller 11. Thus, the driving belts 10 of the two adjusting belts 6 and 6 are rotationally driven in opposite directions via a transmission means such as a chain by a driving motor 12 mounted on the support frame 9 via a bracket. The belt portions located on the inner surface of the hopper 1 are configured to be circularly moved (rotated) in the direction from the lower portion to the upper portion.

As shown in FIG. 1 and FIG. 2, on the surface of the adjusting belts 6, 6, a large number of strip-shaped projections 13 to 13 which are inclined downward from both widthwise edges toward the center are formed. It is protruded by sandwiching it and displacing it from each other in the left and right directions in the drawing. Further, the adjusting belts 6, 6 are guided by a plurality of guide rollers 14 to 14 rotatably installed between the driving roller 10 and the driven roller 11 in the substantially central portion between the side walls 4 and 5.
The width of the discharge port 8 formed under the adjusting belts 6, 6 is set to be slightly wider than the tire width of the relatively large waste tire Tb. Guide plates 8a, 8a facing a first conveyor 15 described later are formed in the lower part of the edge between the both side walls 4, 5. However, one end (the right end in FIG. 1) of the guide plates 8a, 8a extends from the side wall 5 to form an outlet passage 8b.

The transfer conveyor 2 is aligned with the first transfer conveyor 15 located below the hopper 1, and is aligned on the same straight line as the first transfer conveyor 15, and one end of the transfer conveyor 2 is predetermined with the first transfer conveyor 15. A second transport conveyor which is opposed to the vertical transfer conveyor 3 at an interval and is opposed to the vertical transfer conveyor 3.
It consists of 16 and. The conveyor 15 is hung across a frame 17 framed in a horizontally long shape, and a driving roller 18 and a driven roller 19 rotatably supported at substantially both ends (left and right parts in FIG. 1) of the frame 17. And an endless conveyor belt 20. The conveyor belt 20 has an upper belt portion facing below the discharge port 8 of the hopper 1, and drives the drive roller 18 from a drive motor 21. It is configured to be circularly moved (rotated) toward the second conveyor 16 side by being rotationally driven via a transmission means such as a gear. The conveyor belt
The distance between the upper surface of 20 and the lower portion of the hopper 1 is set to be slightly larger than the diameter of the large-sized waste tire Tb housed in the hopper 1.

The second transfer conveyor 16 is the first transfer conveyor 15
Similarly to the above, the frame 22 is framed in the shape of a horizontally long frame, and the endlessly mounted around the drive roller 23 and the driven roller 24 rotatably supported at substantially both ends (left and right parts in FIG. 1) of the frame 22. The conveyor belt 25 is shaped like a conveyor belt 25. The conveyor belt 25 has its upper belt portion positioned slightly below the upper surface of the conveyor belt 20 of the first conveyor 15 and drives the drive roller 23. Circulation movement (rotation) toward the vertical transfer conveyor 3 side by rotationally driving the motor 26 via a transmission means such as a chain.
Is configured to. Further, guide plates 27, 27 are vertically provided on both upper edges of the frame 22 along the longitudinal direction in a state of being aligned with the guide plates 8a, 8a of the hopper 1 side at the same intervals. An alignment regulating member 28 is horizontally rotatably supported on the front side of the vertical transfer conveyor 3 on 22 and the tip of the alignment regulating member 28 is a waste tire.
It extends obliquely in the direction of Ta transport, and is urged by a spring 29 elastically mounted on its bearing so as to always rotate toward one guide plate 27. A stopper 30 is provided on the other end of the frame 22 to stop the conveyed waste tire Ta at a predetermined portion facing the vertical transfer conveyor 3.
And a transfer plate 31 is obliquely installed between the first transfer conveyor 15 and the second transfer conveyor 16.

The vertical transfer conveyor 3 has a vertically long frame 32 and a chain arranged vertically circulatory (rotatable) with respect to the frame 32 via a transmission means such as a chain by a drive motor 33a. The chain conveyor 33 has a plurality of hooking pieces 34 to 34 projecting from the outer peripheral surface of the chain conveyor 33 facing the second transfer conveyor 16 side at a predetermined interval. Then, the waste tire Ta located at the position stopped by the stopper 30 of the second conveyor 16 is successively hooked and conveyed upward.

A transport path 35 for transporting the waste tire Ta transported upward by the chain conveyor 33 to the combustion furnace (not shown) is located above the vertical transport conveyor 3.

Exclusion means 36 for selecting and extracting large waste tires Tb from the support frame 9 on the side wall 5 side of the hopper 1
The removing means 36 is equipped with a pair of gear-like removing rollers 37, 3 facing each other on both sides of the outlet passage 8b with a predetermined interval with respect to the bracket 36 fixed to the support frame 9.
The drive motor 38 is supported by the drive motor 38 so as to be positively rotatable in opposite directions via a transmission means such as a chain. These exclusion rollers 37, 37 are large waste tires T whose outer diameter should be excluded.
While being formed to have a diameter slightly larger than the inner diameter of b, only the large waste tire Tb on the conveyor belt 20 of the first conveyor 15 is pressed from the side surface and discharged upward from the conveyor belt 20. The height is set appropriately. In addition,
The removing means 36 is provided with a gutter (not shown) for receiving the large waste tire Tb discharged upward.

Next, the operation of the waste tire supply device of the present example configured as described above will be described.

Now, when the drive motors 12, 21, 26, 33a, 38 are respectively driven, the pair of adjusting belts 6, 6 in the hopper 1 move the belt portions located on the inner surface of the hopper 1 in the direction of the arrow O from the bottom to the top. It is circulated and moved (rotated), and the transport belt 20 and the second transport conveyor in the first transport conveyor 15 are moved.
1, the conveyor belts 25 are cyclically moved (rotated) in the direction of arrow P in FIG. 1, that is, toward the vertical transfer conveyor 3 side, and the chain conveyor 33 in the vertical transfer conveyor 3 is the second transfer conveyor 16 The conveyor unit facing the above is circularly moved (rotated) in the direction of arrow Q from below to above, and the pair of exclusion rollers 37, 37 in the exclusion means 36 are positively rotated in directions opposite to each other in the direction of arrow R.

Therefore, when a relatively small waste tire Ta and a relatively large waste tire Tb are randomly introduced into the hopper 1 from the input port 7, the waste tire Ta or Tb in the hopper 1 has its diameter direction and the discharge port 7. The sheet is discharged from the discharge port 7 onto the transport belt 20 of the first transport conveyor 15 in a state of standing up when the position thereof coincides with the longitudinal direction.

At this time, the waste tire Ta or Tb whose longitudinal direction and the diametrical direction of the discharge port 7 do not coincide with each other, and a plurality of waste tires Ta or Tb located at the discharge port 7 and caught in the discharge port 7 For Ta or Tb, adjust belt 6,6
Is circulated (rotated) in the direction of the arrow O to constantly give upward movement force to the waste tire Ta or Tb, and the surface of the tire is directed toward the center from both edges in the width direction. A large number of strip-shaped projections 13 to 13 that are inclined downward are projected to forcibly give the waste tire Ta or Tb a deflection action in the direction along the conveyor belts 6 and 6 when moving upward. As a result, the waste tire Ta or Tb in the above-described state has the longitudinal direction of the discharge port 7 and the diametrical direction thereof aligned with each other.
It is discharged onto the transport belt 20 of the transport conveyor 15 of FIG.

Next, while the waste tire Ta or Tb on the conveyor belt 20 of the first conveyor 15 is kept standing together with the conveyor belt 20 by the guide plates 8a, 8a in the exit passage 8b, inside the hopper 1. It escapes from the outlet passage 8b and passes below the excluding means 36.

At this time, the relatively small waste tire Ta is horizontally conveyed as it is along with the conveyor belt 20, and the second conveyor 16 is used.
The relatively large waste tire Tb is conveyed to the side of the conveyor belt 25 of FIG. 1, but a part of its outer diameter is eaten by the exclusion rollers 37, 37 which are positively rotated in the directions opposite to each other in the direction of arrow R. While being pressed from the side surface in this state, it is lifted up from above the conveyor belt 20 and discharged to a gutter (not shown) or the like. In this case, since the exclusion rollers 37, 37 are formed so that the outer diameter thereof is slightly larger than the inner diameter formed in the large-sized waste tire Tb to be excluded, the waste roller Tb can surely be held until the end. Can be raised.

Then, the waste tire Ta conveyed to the side of the conveyor belt 25 of the second conveyor 16 rolls on the transfer plate 3 from the conveyor belt 20 of the first conveyor 15 and moves to the lower second conveyor. It is transferred onto 16 conveyor belts 25. The waste tire Ta on the conveyor belt 25 is conveyed together with the conveyor belt 25 while being kept upright by the guide plates 27, 27, and is conveyed to the stopper 30 at a portion facing the vertical conveyor 3 side, and the stopper The conveyance is stopped at the 30th position, and the conveyance belt 25 temporarily stands by.

At this time, the waste tire Ta is conveyed by the alignment restricting member 28 while being moved to the one guide plate 27 side, and is positioned at a portion facing the vertical transfer conveyor 3 side.

Subsequently, the waste tire Ta temporarily waiting on the conveyor belt 25 is circulated (rotated) in the Q direction from the bottom to the top of the conveyor section facing the second conveyor 16 for vertical transfer. An inner diameter portion of the chain conveyor 33 is hooked by a hooking piece 34 of the chain conveyor 33 and is sequentially conveyed upward.

Then, the waste tire Ta conveyed upward is supplied to the conveying path 35 and is then supplied from the conveying path 35 to the combustion furnace (not shown).

In this example, the waste tires Ta are successively supplied to the combustion furnace (not shown) as described above, and in particular, the exclusion means 36 provided in the outlet passage 8b in the hopper 1 makes it possible to provide a relatively small size. The waste tire Ta can be horizontally conveyed together with the conveyor belt 20 and can be conveyed to the conveyor belt 25 side of the second conveyor 16 so that the waste tire Ta is not suitable for supply to the combustion furnace (not shown). The tire Tb is an exclusion roller that is positively rotated in opposite directions in the direction of arrow R.
The hopper is capable of being lifted upward from above the conveyor belt 20 and discharged to a gutter (not shown) or the like while being pressed from the side while a part of its outer diameter is covered by 37,37. It is possible to automatically perform the sorting work of the waste tires randomly placed in 1 and the removing work thereof.

(Effects of the Invention) As described above, according to the present invention, the waste tires randomly placed in the hopper are cyclically moved from the lower outlet side to the upper inlet side, and the oblique belt-like protrusions are formed on the surface. While adjusting to an upright state by a pair of adjusting belts having parts, the lower discharge port sequentially discharges it onto a lower conveyer conveyor, and then the conveyer conveys it while maintaining its upright state by the guide means, and vertically. The waste tires can be supplied to the vertical transfer conveyor one by one by sequentially arranging the waste tires with respect to the transfer conveyor by the aligning means, and the waste tires can be automatically and efficiently supplied, and the workability is greatly improved.
