Abstract

PURPOSE:To remove water and wheels by supplying tires from a hopper to a conveying apparatus, conveying the tires under oscillation, and removing wheel-carrying tires from the conveying route at a signal from a wheel-detecting means. CONSTITUTION:Tires T in a hopper 2 are conveyed on a belt conveyor 6 and dropped onto the upper end of an oscillating plate 12 of an oscillating mechanism 3. The tires T on the plate 12 are oscillated in the direction of the conveyor and in the vertical direction by the action of a drive motor 13 and a crank arm 14, thus expelling rain water, etc., present in the inside of the tires T to the outside. The tires T are aligned in a row with a guiding member 11, sent one by one to a roller conveyer 16, and passed through under a wheeldetecting means 4. When the means 4 detects a wheel-carrying tire, then a control unit sends a drive signal to a foreign-matter-removing mechanism 5 to rotate a supporting member and thereby to deliver the tire to a treating means through a discharge roller conveyer 25. On the other hand, tires T carrying no wheel are delivered to a carbonization oven through a delivery conveyor 26.

Each piece is sent to the roller conveyor 16 in the subsequent stage.

The tire T fed to the roller conveyor 16 in this way is moved to the downstream side while sliding on the roller conveyor 16, and is passed under the wheel detecting means 4 in the middle thereof.

When the tire T is fed below the wheel detecting means 4, the wheel detecting means 4 detects whether or not a wheel is mounted at the center of the tire T, and based on this detection result, the control unit. The foreign matter removing mechanism 4 is controlled by.

That is, in the wheel detecting means 4,
When it is determined that the wheels of the conveyed tire T have been removed, the drive signal to the foreign matter removing mechanism 5 is not output,
Each roller 19 is held in a horizontal state as shown in FIG.
The upper part is conveyed to the downstream side.

When the wheel detecting means 4 determines that the wheel is mounted on the conveyed tire T, a drive signal is output from the control unit to both actuators 20 of the foreign matter removing mechanism 5, and these are transmitted to them. The support members 18 connected to each other are each rotated about 90 °.

By the rotation of each support member 18 as described above,
As shown by the arrow in FIG. 3, the rollers 19 attached to each are swung so that the free end side thereof is downward, and the middle of the roller conveyor 16 is largely opened.

1 (only one of the supporting members is shown in the drawing) and the supporting members 31 are hung between the supporting members 31.
A plurality of rollers 32 that are rotatably supported by the roller 32 and that are provided at intervals in the transport direction; an actuator 33 that integrally rotates both support members 31 downward; Of the tire T provided above the roller 32 and conveyed on the roller 32.
And the stopper 34 which is brought into contact with the stopper 3
4 is composed of an actuator 35 that moves the roller 4 toward and away from the roller 32.

The support member 31 is rotatably supported by a pivot 36 at its downstream end.

In the foreign matter removing mechanism 5 of the present embodiment having such a configuration, the supporting member 31 is normally positioned so as to be parallel to the conveying direction of the roller conveyer 16, and one of the roller conveyer 16 is moved. That is, the stopper 34 is held in a state of being projected to the vicinity of the roller 32.

The tire T discharged from the swing mechanism 3 is temporarily stopped by the stopper 34,
At this point, the presence / absence of a wheel is detected by the wheel detecting means 4.

Here, when the wheel detecting means 4 determines that the wheel is not mounted, a driving signal is output to the actuator 35 and the stopper 34 is raised, so that the tire T is released. It is conveyed downward and is sent to the dry distillation furnace via the feeding conveyor 26 and the like in the latter stage.

When the wheel detecting means 4 detects a wheel, the control unit causes the actuator 3 to move.
A driving signal is output to 3 and both support members 31 and the roller 32 are swung downward around the pivot 36, so that the lower portion of the transport path is largely opened.

As a result, the foreign matter T located on the roller 32 of the foreign matter removing mechanism 30 is discharged below the foreign matter removing mechanism 30.

According to the foreign matter removing mechanism 30 of this embodiment, the tire T to be discharged is discharged in a substantially vertical state. Carrying out in such a posture is, for example,
The transport mechanism for the discharged tire T is a mere flat surface,
This is because, when the tire T is configured to be rolled and discharged on this plane, the tire T can be smoothly rolled by dropping it on the plane in a vertical state.

The shape, size, arrangement, etc. of each constituent member shown in the above embodiment are merely examples.
Various changes can be made based on design requirements.

For example, while the rollers 19 and 32 are used as the means for transporting the tire T in the foreign matter removing mechanisms 5 and 30 in each of the above embodiments, instead of this, as shown in FIG. It is also possible to carry out the transportation using the weight and rolling of the tire T.

With this construction, the posture of the tire T discharged from the swinging mechanism 3 is adjusted to a vertical state, and the first guide cylinder 40 that rotates 90 ° about the vertical line and the first guide cylinder 40 are used. A second guide cylinder 41 that is continuously provided in the conveying direction from the above to guide the tire T in a vertical state, an opening / closing plate 42 provided at the bottom end of the end of the second guide cylinder 41, and the opening / closing plate. A stopper 43, which is mounted in the second guide cylinder 41 in the vicinity of 42 so as to be able to move forward and backward, contacts the tire T conveyed in the second guide cylinder 41, and temporarily stops the tire T. The second guide cylinder 41 is provided so as to be inclined downward toward the downstream side.

With such a structure, the tire T can be moved while rolling inside the guide members 40 and 41.
