Description

An Apparatus for Processing a Vehicle Tyre FIELD OF THE INVENTION This invention relates to an apparatus for processing a vehicle tyre by cutting the tyre into portions, more especially an apparatus for removing the sidewalls from tyres and in particular to an apparatus for processing tractor tyres and large truck tyres.
BACKGROUND OF THE INVENTION Worn vehicle tyres are among the largest and most problematic sources of waste, due to the large volume produced, their durability, and the fact they contain a mixture of components that are ecologically problematic. Tyres typically comprise a mixture of steel wires, textile cords and rubber.
Tyres can sometimes be re-treaded and re-used but often the only option is to recycle them or dispose of them in landfill, particularly if they are badly damaged. A problem with recycling tyres is the difficulty in handling, storage and transportion of the tyres due to their shape, size and volume. This is a particular problem with large tyres, such as tractor tyres It is therefore desirable to cut tyres into smaller portions, in particular removing the sidewalls from the tread, to allow them to be compressed in size and/or flat-packed, thus greatly reducing the space they take up and maximizing the amount that can be transported at once. Separating the sidewalls, typically comprising rubber and textile materials, from the tread of the tyre, typically containing steel, facilitates recycling and makes it easier for the tyres to be baled for storage and transportion.
While devices have been provided for cutting the sidewalls out of car and truck tyres, such known devices are generally unsuitable for processing larger truck tyres and tractor tyres due to the size and weight of such tyres. US 5,235,888 discloses a known tyre sidewall cutting machine wherein a tyre can be placed over a pair of support rollers before a cutter assembly is brought down over the tyre such that tyre is clamped between an upper roller and the support rollers and a pair of cutting blades engage the tyre to separate the sidewalls of the tyre from the tread. A problem with such machine is that the tyre must be physically lifted up to be placed over the support rollers of the machine. Furthermore, large and heavy tractor tyres tend to loose rigidity as soon as the relatively deep sidewall is cut, causing problems with uncontrolled movement of the tyre during cutting and loss of control of the cutting operation.
An object of the present invention is to provide an improved tyre processing apparatus that can readily handle large tyres, such as tractor tyres.
SUMMARY OF THE INVENTION According to the present invention there is provided an apparatus for processing a vehicle tyre by cutting the tyre into portions, the apparatus comprising a base having a cutting blade mounted thereon for cutting a sidewall of a tyre, a cantilevered tyre support mast pivotally mounted on the base to be movable between a lowered position, wherein a tyre may be located over the tyre support mast, and a raised position, wherein the tyre support mast supports the tyre against the cutting blade during a cutting operation, the tyre support mast including an abutment member arraned to be located inside of the tyre when the tyre support mast is in its raised position and having a reciving slot adapted to receive a portion of the cutting blade when the tyre support mast is in its raised position, a pair of tyre support members being mounted on the tyre support mast, said support members being laterally spaced on either side of said abutment member, said tyre support members being adapted to engage an inner surface of the tyre such that the tyre rests upon the support members when the tyre support mast is in its raised position, wherein at least one drive wheel is mounted adjacent the cutting blade for rotating the tyre during a cutting operation, said at least one drive wheel engaging the abutment member of the tyre support mast when the tyre support mast is in its raised position.
Preferably said tyre support members are adjustably mounted on the tyre support mast such that the height of the tyre support members with respect to the abutment member can be adjusted. An actuator, such as a double acting hydraulic ram, may be provided for adjusting the height of the tyre support members with respect to the abutment member.
In a preferred embodiment each tyre support member comprises a roller facilitating rotation of the tyre when supported thereon.
Said cutting blade may comprise a cutting disc having a peripheral cutting edge, said disc being rotatable about a substantially vertical axis. The abutment member may comprise a roller rotatable about a substantially vertical axis when the tyre support mast is in its raised position, said receiving slot comprises a circumferential groove for receiving the cutting disc when the tyre supper mast is in its raised position. The at least one drive wheel may be mounted coaxially with said cutting disc, preferably on a common drive shaft. A pair of drive wheels may be provided mounted on either side of the cutting disc.
The at least one drive wheel may be provided with peripheral teeth for drivingly engaging the tyre.
The at least one drive wheel may be driven by a motor to rotate the tyre past the cutting blade to facilitate cutting of the sidewall of the tyre.
The base of the apparatus may include a substantially vertical front face upon which the cutting blade and the tyre support mast are mounted.

DETAILED DESCRIPTION OF THE DRAWINGS An apparatus for processing a vehicle tyre in accordance with an embodiment of the present invention, as illustrated in the drawings, comprises a base frame 2 having a front face 4 upon which is mounted a cantilevered tyre support mast 6 and a cutting disc 8 adapted for cutting a sidewall of a tyre.
The cantilevered tyre support mast 6 is pivotally mounted on a lower side of the front face 4 of the base frame 2 to be movable between a lowered position (shown in Figure 2), wherein a tyre 1 may be located over the tyre support mast 6, and a raised position (shown in Figure 1), wherein the tyre support mast 6 supports the tyre 1 against the cutting blade 8 during a cutting operation, under the action of a double acting hydraulic ram 10.
An abutment roller 12 is mounted at an outer end of the tyre support mast 6 to be located inside the tyre 1 for providing a member against which the cutting disc 8 can act, the abutment roller 12 incorporate a circumferential groove 14 arranged to receive the cutting disc 8 when the tyre support mast 6 is in its raised position. The abutment roller 12 is mounted to be rotatable about an axis subtantially aligned with the longitudinal axis of the mast 6 such that the axis of the abutment roller 12 is substantially parallel to the axis of the cutting disc 8 when the tyre support mast 6 is in its raised position.
Drive wheels 16 (only upper drive wheel shown in drawings) are mounted coaxially above and below the cutting disc 8 on a common drive shaft 18, arranged to engage an outer surface of the abutment roller 12 when the tyre support mast 6 is in its raised position such that the tyre sidewall can be clamped between the drive wheels 16 and the abutment roller 12, the drive wheels 16 being driven by an electric or hydraulic motor to facilitate rotation of tyre during cutting. Teeth 17 may be formed on the peripheral edge of each drive wheel 16 to provide enhanced grip against the tyre.
A pair of tyre support rollers 20,22 are mounted on the tyre support mast 6, located on either side of the abutment roller 12, the tyre support rollers 20,22 being adapted to engage an inner surface of the tyre such that the tyre rests upon the support rollers 20,22 when the tyre support mast 6 is in its raised position, rotation of the support rollers 20,22 facilitating rotation of the tyre during cutting.
Each tyre support roller 20,22 is rotatably mounted at a distal end of a respective support arm 24,26, the support arms 24,26 being mounted on a carriage 28 slideably mounted on the tyre support mast 6 for movement along the axis of the support mast 6 such that the height of the tyre support rollers 20,22 with respect to the abutment roller 12 can be adjusted to adjust the height of the tyre with respect to the cutting disc 8 and to suit the diameter of the tyre being cut. A double acting ram may be provided for adjusting the height of the support rollers. The length of the support arms 24,26 may be adjustable to adjust the position of each support roller 20,22 with respect to the carriage 28. Each supprt arm 24,26 may comprise two telescopically arranged sections which may be fixed at a desired length by meanas of alignes pairs of holes 27 into which may be inserted a respective locating pin. Furthermore, each support arm 24,26 may be pivotally mounted on the carriage 28 and the angle at which each support arm 24,26 extends from the carriage may be adjustable to adjust the height of and spacing between the support rollers 20,22, as illustrated in Figures 6 and 7, the angle of each support arm 24,26 beng fixed by means of locating pins inserted through respective aligned holes 29 in the respective support arm 24,26 and carriage 28.
Further support members 30 may be mounted on the support roller carriage 28 below the abutment roller 12, extending towards the front face 4 of the base frame 2 when the support mast is in its raised position, wherein said further support members 30 may be utilised to support the bead of the tyre, particularly when cutting the bead away from the remainder of the sidewall of the tyre, as will be described below in more detail.
Transversely extending support bars 32,34, which may have rollers mounted thereon, may be provided on one or both sides of the support mast 6 for supporting the tyre when the mast 6 is in its raised position and for preventing twisting/rotation of the tyre about a vertical axis.
A wear plate may be provided on a distal end of ths tyre support mast 6. However, it is not intended that the tyre normally rest upon the end of the support mast 6. Instead it is intended that the tyre 1 be supported upon the support rollers 20,22 on either side of the support mast 6.
In use, a tyre 1 is located in front of the front face 4 of the base frame 2 with the support mast 6 in at least a partially lowered position, as shown in Figure 4, with the upper side of the tyre 1 located over a distal end of the support mast 6. The relevant ram 10 is operated to raise the support mast 6 towards its raised position. As the support mast 6 is raised, the support rollers 20,22 and the engagement roller 12 engage the inside of the tyre so that the tyre is supported on the support rollers 20,22 and moved into engagement with the cutting disc 8, the cutting disc 8 being forced through the sidewall of the tyre 1 as the cutting disc is pressed into the receiving groove 14 in the abutment roller 12. At the same time the sidewall of the tyre is clamped between the abutment roller 12 and the drive wheels 16. The drive shaft 18 of the drive wheels16 and cutting disc 8 is driven to rotate the tyre such that the cutting disc cuts a circular cut around the sidewall of the tyre, separating the sidewall from the tread.
Once one sidewall has been separated from the tread of the tyre, the support mast 6 may be moved towards its lowered position, permitting removal of the separated sidewall from the apparatus, and the tyre may be rotated about a vertical axis to being the second sidewall into a cutting position facing the front face 4 of the base frame 2 of the apparatus. The support mast 6 may then be raised to bring the tyre into a cutting position once again and the drive wheels 16 and cutting disc 8 driven such that the cutting disc 8 separates the second sidewall of the tyre 1 from the tread. The support mast 6 may again be lowered to permit removal of the sidewall and the remaining tread from the apparatus.
If desired, each sidewall, once separated from the tread, may be placed on the apparatus to cut away the steel bead from the respective sidewall. This is achieved by moving the support mast 6 towards its lowered position and placing the sidewall such that the bead portion rests upon the further support members 30 of the support wheel carriage 28 on the support mast 6. The carriage 28 may be raised on the mast 6 to position the sidewall such that the cutting disc 8 is adjacent the bead of the sidewall and the support mast 6 moved to its raised position to bring the cutting disc 8 into engagement with the abutment roller 12 and the drive wheels 16 may be driven to cut the bead away form the sidewall.
A guard 36 may be provided on the front face 4 of the base frame 2 of the apparatus for protecting the operator. The controls 38 for operating the various rams to raise and lower the tyre support mast 6, adjust the position of the support rollers 20,22 and to operate the drive wheels 16 may be provided on a side of the base of the apparatus, such that the operator is not exposed to the front face 4 of the base frame 2 during operation of the apparatus. One or more emmergency stop buttons 40 may be provided on or adjacent the front face of the base and/or on a side of the apparatus.
The invention is not limited to the embodiment(s) described herein but can be amended or modified without departing from the scope of the present invention.
