  • an electrical motor is mechanically coupled to the shredding head and a current monitoring device monitors the flow of electrical current to the motor.
  • a current monitoring device monitors the flow of electrical current to the motor.
  • a reversing circuit is energized to reverse the motor for a short period of time to expel the tire.
  • the exemplary embodiment of the invention achieves the foregoing objects in a structure including a cutting head having a pair of parallel shafts, each of which bears cutting and feeding devices which coact with the cutting and feeding devices on the other shaft to shred a tire.
  • the shafts are intended to be rotated in opposite directions and to this end, a pair of bidirectional, hydraulic motors are provided, one for each shaft.
  • the hydraulic motors are included in parallel in a closed hydraulic circuit with a hydraulic pump.
  • the pump may be driven by any suitable means such as an electric motor and the hydraulic circuit includes means whereby the direction of fluid flow may be changed so as to reverse the direction of rotation of both motors simultaneously.
  • a pressure sensing device is associated with the hydraulic circuit and, when pressure in the same rises to exceed a predetermined value, the same is operative to cause reversal of the direction of flow of hydraulic fluid to reverse the bidirectional hydraulic motors for a short period of time sufficient to partially expel a tire.
  • a unidirectional volumetric flow rate control valve is located in the hydraulic circuit between the two motors so that, when the motors are operating in a relatively unloaded condition, one of the motors will rotate at a different rate than the other to thereby cause the associated shaft to rotate at a different rate than the other to promote selfcleaning of accumulated rubber strips between the cutting devices on the two shafts.
  • the invention also contemplates a bidirectional pressure relief valve across the pump so that, should the reversing operation fail for any reason, a bypass circuit is immediately established to preclude damage to the components.
  • FIGURE is aschematic illustration of a tire shredding apparatus made according to the invention.
  • FIG. 1 An exemplary embodiment of a tire shredding machine made according to the invention is illustrated in the FIGURE and is seen to include two main components, including a power pack, generally designated 10, and a cutting apparatus, generally designated 12, which may be, in practice, disposed some distance from each other.
  • a power pack generally designated 10
  • a cutting apparatus generally designated 12
  • the same includes a cutting head, generally designated 14, which may be configured as disclosed in the commonly assigned Cunningham et al. application, Ser. No. 396,185, filed Sept. 11, 1973, the details of which are herein included by reference; or which may take on other configurations as known in the art.
  • the cutting head 14 includes a cutter box 16 through which a pair of parallel shafts 18 extend.
  • the shafts 18 are rotatable and each mounts cutting and feeding means shown schematically at 20 which coact to feed, cut and shred tires in a manner such as that disclosed in the above identified Cunningham et al. application.
  • a pair of bidirectional hydraulic motors 22 and 24 are respectively associated with the shafts 18, the arrangement being such that the shafts 18 will be rotated in opposite directions.
  • the hydraulic motors 22 and 24 are connected in parallel between hydraulic lines 26 and 28. In normal operation, the line 26 will be the high pressure line, while the line 28 will be the low pressure line. However, this will not always be the case, as will be seen.
  • each motor 22 and 24 includes a connection to a drain line 30 which extends to a hydraulic fluid reservoir 32 located within the power pack 10.
  • the line 26 includes, at a location between the motors 22 and 24, a unidirectional, volumetric flow rate control valve system, generally designated 34.
  • the same includes a flow control valve 36 which may be in the form of a needle valve, and a checkvalve 38 connected in parallel.
  • the flow control valve 36 is connected in the line so as to limit the volume of hydraulic fluid flowing to the motor 24 while not restricting the volume of hydraulic fluid flowing to the motor 22, when the line 26 is the high pressure line.
  • the flow control valve 36 becomes ineffective by reason of the parallel circuit including the check valve 38 which will open at that time.
  • the cutting apparatus also includes a bidirectional, pressure relief valve 39 across the lines 26 and 28. While the valve 39 is shown as being located within the cutting apparatus, it is to be expressly understood that the same could be located in the power pack so long as the same is connected across lines 26 and 28.
  • the cutting apparatus 12 may include a stopstart switch 40 which is connected to the power pack,
  • the reservoir 32 receives oil from the line 30 and includes an outlet line 44 including a filter 46 to a charge pump 48 for a bidirectional hydraulic pump 50 of the swash plate type.
  • the pumps 48 and 50 are conventional and the latter is connected to the lines 26 and 28 to define a closed loop hydraulic circuit.
  • the pump 50 may be driven by a conventional electric motor 54 having an electrical motor starting circuit 56 of conventional design.
  • the starter circuit 56 is connected to the line 42 as well as to a further stop-start switch 58.
  • the motor 54 can be energized or de-energized either at the location of the power pack or at the locationof the cutting apparatus 12.
  • the same includes a swash plate control linkage 60 which is connected to the armature of a solenoid 62.
  • the line 26 When the linkage 60 is in the dotted line position shown in the FIGURE, the line 26 will be the high pressure line.
  • the solenoid when the solenoid is energized to move the linkage to the solid line position shown in the FIGURE, the line 28 will become the high pressure line by reason of the change in position of the internal swash plate of the pump 50 reversing the direction of fluid flow.
  • the solenoid 62 is connected electrically to be energized by a conventional time delay relay 64 which is powered by a low voltage power supply 66 connected to the electrical motor starter circuit 56. Control of the relay 64 is obtained from a pressure switch 68 which is connected to sense the pressure in the line 26.
  • the pressure switch 68 is adjustable and is arranged so that when the pressure in the line 26 exceeds a predetermined value, it will energize the relay 64 to in turn energize the solenoid 62 to shift the swash plate linkage 60 to the reverse position.
  • the relay 64 is adjustable and is arranged so that when the pressure in the line 26 exceeds a predetermined value, it will energize the relay 64 to in turn energize the solenoid 62 to shift the swash plate linkage 60 to the reverse position.
  • the relay 64 is adjustable and is arranged so that when the pressure in the line 26 exceeds a predetermined value, it will energize the relay 64 to in turn energize the solenoid 62 to shift the swash plate linkage 60 to the reverse position.
  • r 4 being a time delay relay, will maintain the solenoid 62 energized for a predetermined time period notwithstanding a drop in pressure in the line 26 which will occur upon reversal of the pump 50.
  • the motor 24 will rotate its associated shaft 18 at a lesser rate than the rate of rotation of the shaft 18 associated with the motor .22.
  • the motor 22 will rotate its shaft at approximately 42 rpm, while the motor 24 will rotate its shaft at approximately 22 rpm
  • the flow control valve 36 provides for the elimination of refuse between the cutting elements when the device is operating under a no-load condition.
  • the motors 22 and 24 will tend to drive their shafts at the same rate of rotation.
  • the pressure switch 68 will sense such an occurrence and throw the system into reverse by shifting the swash plate linkage 60. This will cause the motors 22 and 24 to rotate their respective shafts in directions opposite that of the arrows shown in the FIGUREwith the result that the tire will be moved backwardly and out of the cutting nip in the cutting head. Such action will continue to occur for the period established by the time delay relay 64. Once the relay 64 has timed out, the solenoid 62 will be deenergized with the result that the swash plate linkage 60 will be returned to its forward position thereby caus ing the line 26 to again become the high pressure line to reinitiate cutting of the tire.
  • check valve 38 insures that during such reverse energization of the system, both motors 22 and 24 will be driven at approximately the same rate, there being no restriction on the volumetric flow to the motor 24.
  • the purpose of this function is to insure rapid clearing of the cutting nip.
  • the pressure relief valve 39 which may be r set to open at a slightly higher pressure than the setting on the pressure switch 68, will open to effectively shunt the flow of fluid to the motors 22 and 24before the sys tem can stall thereby precluding damage to the system.
  • a shredding machine made according to the invention possesses substantial advantages over the prior art apparatus.
  • the same is constructed so that damage to an electrical drive motor such as the motor 54, due to overloading cannot occur even when load sensing and reversing equipment including the pressure switch 68 may fail.
  • the system accomplishes, through the use of a flow control valve 36, a self-cleaning action without the need for special mechanical components to achieve this action.
  • the use of independent drives for the shafts l8 and the cutting head eliminate the need for expensive, heavy duty gearing that would be subjected to substantial probability of failure due to the high loading conditions encountered in tire shredding operations.
