Abstract

A diagnostic system for a compactor/baler includes a controller and a plurality of switches coupled to inputs of the controller. A first switch is in a first position when a ram of the compactor/baler is below a predetermined location, and a second position when the ram reaches the location. A second switch is in a first position when pressure driving the ram is below a predetermined pressure limit, and a second position when the ram exceeds the pressure limit. A communication port and display are operatively coupled to outputs of the controller. The controller is configured to, upon actuation of the first switch to the first position, activate a ram timer to count to a predetermined timer setting, and, if the second switch is actuated to the second position before the ram timer reaches the timer setting, output an alert of a full bale condition the communication port and/or display.

Claims

1. A diagnostic system for a compactor/baler apparatus comprising:

(a) a controller having a plurality of inputs and a plurality of outputs;

(b) a plurality of switches each coupled to a respective one of the plurality of inputs of the controller,

(i) a first of the plurality of switches being in a first position when a ram of the compactor/baler apparatus is below a predetermined location and being in a second position when the ram reaches the predetermined location,

(ii) a second of the plurality of switches being in a first position when a pressure driving the ram is below a predetermined pressure limit and being in a second position when the ram exceeds the predetermined pressure limit;

(c) a communication port operatively coupled to a first output of the plurality of outputs of the controller; and

(d) a display operatively coupled to a second output of the plurality of outputs of the controller,

the controller being configured to;

(i) upon actuation of the first switch to the first position, activate a ram timer to count to a predetermined timer setting, and

(ii) if the second switch is actuated to the second position before the ram timer reaches the predetermined timer setting, output an alert indicating a full bale condition to at least one of the communication port and the display.

2. The diagnostic system of claim 1, wherein the controller is further configured to increment a cycle counter each time the ram counter reaches the predetermined timer setting before the second switch is actuated to the second position.

3. The diagnostic system of claim 2, wherein a third of the plurality of switches is in a first position when a bale door of the compactor/baler apparatus is closed and in a second position when the bale door is open.

4. The diagnostic system of claim 3, wherein the controller is further configured to increment a full bale counter when the controller indicates the occurrence of a full bale condition, the cycle counter has been incremented by a predetermined amount since the last indication of a full bale condition, and the third switch has been actuated to the second position.

5. The diagnostic system of claim 1, wherein the controller includes a third output configured to connect a power supply of the compactor/baler apparatus to an up solenoid configured to move the ram upwardly when the up solenoid is connected to the power supply, and a fourth output configured to connect the power supply of the compactor/baler apparatus to a down solenoid configured to move the ram downwardly when the down solenoid is connected to the power supply.

6. The diagnostic system of claim 5, wherein the controller is further configured to output an alert to at least one of the communication port and the display when the first switch is not actuated to the second position during a predetermined time that the up solenoid is connected to the power supply.

7. The diagnostic system of claim 5, wherein the controller is further configured to output an alert to at least one of the communication port and the display when the second switch is actuated to the second position while the up solenoid is connected to the power supply.

8. The diagnostic system of claim 5, wherein the controller is further configured to output an alert to at least one of the communication port and the display when the second switch is not actuated to the second position during a predetermined time that the down solenoid is connected to the power supply.

9. The diagnostic system of claim 1, wherein the controller is further configured to output an alert to at least one of the communication port and the display when the second switch is actuated to the second position for longer than a predetermined time.

10. The diagnostic system of claim 1, wherein the communication port is a telephone modem.

11. The diagnostic system of claim 1, wherein the display is at least one of a liquid crystal display screen and an indicator light.

12. A diagnostic system for a compactor/baler apparatus comprising:

(a) a controller having a plurality of inputs and a plurality of outputs;

(b) a plurality of switches each coupled to a respective one of the plurality of inputs of the controller,

(i) a first of the plurality of switches being in a first position while a start down button is actuated to initiate downward motion of a ram of the compactor/baler apparatus in a downward direction, and otherwise being in a second position,

(ii) a second of the plurality of switches being in a first position when a ram gate of the compactor/baler apparatus is closed and being in a second position when the ram gate is open, and

(iii) a third of the plurality of switches being in a first position when a feed gate of the compactor/baler apparatus is open and in a second position when the feed gate is closed,

(c) a communication port operatively coupled to a first output of the plurality of outputs of the controller;

(d) a display operatively coupled to a second output of the plurality of outputs of the controller;

(e) a down solenoid selectively connectable to a power supply of the compactor/baler apparatus by a third output of the plurality of outputs of the controller, the down solenoid being configured to move the ram in a downward direction when connected to the power supply; and

(f) an up solenoid selectively connectable to the power supply by a fourth output of the plurality of outputs of the controller, the up solenoid being configured to move the ram in an upward direction when connected to the power supply,

the controller being configured to;

(i) increment a cycle counter following completion of a sequence wherein the down solenoid is connected to the power supply for a first period of time and subsequently the up solenoid is connected to the power supply for a second period of time, and

(ii) output an alert to at least one of the communication port and the display based upon detection, by the controller, of a predetermined configuration of the plurality of switches.

13. The diagnostic system of claim 12, wherein the plurality of switches further includes:

(iv) a fourth of the plurality of switches being in a first position while an emergency stop button is actuated to stop operation of the compactor/baler apparatus, and otherwise being in a second position,

(v) a fifth of the plurality of switches being in a first position when an overload circuit breaker of the compactor/baler apparatus is tripped, and otherwise being in a second position, and

(vi) a sixth of the plurality of switches being in a first position when a key on/off switch of the compactor/baler apparatus is turned off and being in a second position when the key on/off switch is turned on, and

wherein the controller is configured to output an alert when at least one of (i) the fourth switch is actuated from the second position to the first position, (ii) the fifth switch is actuated from the second position to the first position, or (iii) the sixth switch is in the first position.

14. The diagnostic system of claim 12, wherein the controller is configured to output the alert when the first switch is in the first position and the second switch is in the second position.

15. The diagnostic system of claim 12, wherein the controller is configured to output the alert when the cycle counter is incremented by a predetermined amount and the third switch has not been actuated from the second position to the first position.

16. The diagnostic system of claim 12, wherein the communication port is a telephone modem.

17. The diagnostic system of claim 12, wherein the display is at least one of a liquid crystal display screen and an indicator light.
