Hardware Overview
Milk Jug Toss hardware features a dual sensor scoring unit, a conveyor belt, and a 12‑V motor. The sensor module houses two infrared units with red LED indicators that flash during attract mode and dim when the game is active; The belt tension roller keeps ball speed steady smooths fast acceleration.
Score Sensor System
The Milk Jug Toss scoring subsystem relies on a pair of infrared proximity sensors mounted beneath the target area. Each sensor is paired with a red LED that provides a visual status indicator. In attract mode the LEDs pulse rapidly, signaling that the system is ready and awaiting player input. When a coin is inserted and the game enters active mode, the LEDs extinguish, confirming that the sensors are engaged and the ball detection circuitry is powered.
Sensor placement is critical: the two units are spaced 12 cm apart, centered on the jug’s rim to capture the ball’s trajectory. The sensors are wired to a 12‑V power supply through a dedicated breakout board that includes current limiting resistors and a Schottky diode for reverse‑polarity protection. The sensor outputs feed into a microcontroller that counts passes and updates the score display.
To verify proper operation, check the LED status first. A steady or flashing LED indicates power, while a dark LED during play confirms active detection. If the LED remains lit during gameplay, inspect the power connector for loose contacts and ensure the 12‑V supply is stable. A missing or dim LED may signal a blown diode or a fault in the sensor module, which can be replaced by removing the sensor housing and swapping the unit.
For calibration, position a ball at the center of the target and observe the sensor trigger. The microcontroller should register a single count; double‑counting indicates misalignment. Adjust the sensor angle by rotating the mounting bracket until the trigger occurs precisely when the ball crosses the detection plane. Once calibrated, the system will reliably award points for each successful jug toss.
Wiring diagrams are available in the official manual; the sensor leads terminate in a 4‑pin connector that mates with the control board. The pins are: +12 V, ground, sensor output A, sensor output B. The outputs are open‑collector and require pull‑up resistors to 12 V. When troubleshooting, use a multimeter to verify continuity from the sensor pins to the board, and check for voltage drop across the pull‑up resistor.
Common failure modes include dust accumulation on the sensor lenses, which can be cleaned with a soft brush. Also, vibration from the conveyor belt can loosen the sensor mounting screws; re‑tighten every 200 hours of play. If the system stops detecting balls entirely, replace the entire sensor module as a single unit.
For firmware updates, download the latest sensor firmware from the manufacturer’s support site and flash it via the serial port. The firmware version is displayed on the status screen during boot. Updating ensures compatibility with newer game logic and improves detection accuracy.
Conveyor Belt Mechanism
The Milk Jug Toss conveyor delivers balls from the loading chute to the playfield. It is driven by a 12‑V DC motor mounted on the rear frame, with a timing belt that turns a pulley attached to the belt. The belt itself is a 3‑inch wide, 2‑inch thick rubber track reinforced with a steel backing for durability. The motor’s speed is regulated by a simple potentiometer on the control board, allowing operators to adjust ball velocity between 4 mph and 8 mph.
Installation requires mounting the motor bracket to the rear of the cabinet, aligning the pulley with the belt’s centerline. The belt is routed over a set of idler pulleys that keep tension consistent; the idlers are spring‑loaded and can be tightened by turning the adjustment screw until the belt has a 0.5‑inch sag at the midpoint. The conveyor’s end is fitted with a ball‑guide chute that directs balls into the target area.
Maintenance involves checking belt tension every 200 hours of play. A loose belt will skip, causing missed balls. To adjust, loosen the idler screws, reposition the belt, then retighten. Inspect the rubber track for cuts or wear; replace the belt if the surface shows more than 1 mm of wear. The motor should be inspected for overheating; if the housing feels hot, clean the fan and ensure airflow is unobstructed.
Replacing the belt is straightforward. First, disconnect the 12‑V power supply. Then, remove the motor by unscrewing the mounting bolts. Slide the belt off the pulleys, replace it with a new one, and re‑install the motor. Re‑tension the belt and reconnect power. Test the conveyor by running the machine in test mode; the belt should move smoothly and deliver balls at the set speed.
For troubleshooting, if the belt stalls, check the motor brushes for wear and replace them if necessary. A noisy belt may indicate a misaligned pulley; realign the pulleys and ensure the idler springs are properly seated. If the conveyor runs but balls are not delivered, verify that the ball‑guide chute is clear of obstructions and that the belt is not slipping on the pulleys.
All parts are listed in the official parts catalog; the belt is model MB‑B01, motor is MD‑12V‑DC, and idler pulleys are IP‑3. The conveyor kit can be ordered from the manufacturer’s online store or through authorized distributors. For firmware updates that affect conveyor speed control, download the latest software from the support portal and flash via the serial interface.
Installation & Setup
Connect the 12‑V power supply to the main board, then mount the cabinet on a level surface. Secure the conveyor motor bracket, align the belt, and tighten idler pulleys. Test the sensor LEDs; they should flash in attract mode. Finally, run a quick play test. Check all wiring for continuity.OK!
Electrical Connection Setup
Begin by verifying the 12‑V DC power supply is rated for at least 5 A. Connect the positive lead to the main board’s +12 V terminal, and the negative to the ground rail. Use a 2‑pin connector for the sensor module: pin 1 to +12 V, pin 2 to ground. The infrared emitters and receivers each require a 220 Ω series resistor; solder these between the sensor board and the 12‑V rail. Ensure the red LED indicators receive 12 V through a 1 kΩ resistor to protect them from over‑current. The conveyor motor is driven by a 12‑V DC motor controller; wire the controller’s input to the main board’s motor driver output, and the controller’s output to the motor’s terminals. Use shielded cable for the motor to reduce electromagnetic interference. Verify polarity on all connections before powering the unit. After all cables are connected, perform a continuity test with a multimeter to confirm no short circuits. Finally, secure all wires with zip ties and label each cable for future maintenance. This setup guarantees reliable operation and simplifies troubleshooting. All wiring should be routed away from moving parts and heat sources. Use color‑coded harnesses to identify power, ground, and signal lines. Label each cable with a durable tag for quick reference during maintenance or upgrades. Keep all connections tight and insulated to avoid voltage drops. Document wiring schematics in a log for future reference. Components comply with IEC 60079 for explosion‑prone areas!
Physical Mounting Steps
Mount the main control board onto the rear panel using the four 3‑inch mounting screws provided. Align the board so that the sensor ports face the front of the cabinet and the conveyor drive shaft aligns with the belt pulley. Secure the board with lock washers to prevent vibration. Next, attach the infrared sensor module to the front panel. Use the two 1‑inch mounting brackets; position the emitters 3 inches above the ball release chute and the receivers 3 inches below the chute to create a vertical detection zone. Tighten the brackets with Phillips head screws, ensuring the LED indicators remain visible for status checks. Install the conveyor belt assembly by sliding the belt onto the drive pulley and the return roller. Use the tension adjustment screw to set the belt at a 2‑inch clearance from the ball chute. Lock the roller in place with a set screw. Finally, route the power and signal cables through the cable glands, securing them with zip ties. Verify that all cable pathways are clear of moving parts and that the motor controller is mounted on the side panel with the fan directed outward for cooling. Label each cable with a color‑coded tag for future maintenance. Once all components are mounted, perform a quick visual inspection to confirm proper alignment before powering the unit. For optimal performance, keep the cabinet level, use a calibrated power supply, regularly inspect the belt tension and sensor alignment to prevent misfires during gameplay.
Operation & Gameplay
Milk Jug Toss engages players by launching balls into a rotating jug. The game tracks hits via infrared sensors, awarding points per jug segment. Players can choose single or multi‑ball modes, with a high‑score leaderboard displayed on the cabinet’s LCD. Enjoy!
Game Modes and Scoring
Milk Jug Toss offers two primary play styles: single‑ball and multi‑ball. In single‑ball mode, the player receives one ball per round, with the goal of hitting the rotating jug’s numbered segments. Each successful hit awards points based on the segment’s value, ranging from 50 to 500 points. Multi‑ball mode launches a set of three balls simultaneously, creating a frantic challenge where the scoring system tallies points for every hit across all balls. The game’s scoring algorithm multiplies the base segment value by a difficulty multiplier that increases as the jug’s rotation speed rises. Attract mode displays a looping demo that flashes the score LEDs; when a coin is inserted, the LEDs dim and the game transitions to active play. High‑score tracking is displayed on the cabinet’s LCD, and players can reset the score by pressing the reset button located behind the operator panel; The manual recommends checking the infrared sensor LEDs to ensure accurate point registration.Players can activate a bonus round by hitting the center segment, which awards a temporary 2× multiplier for all subsequent hits until the timer expires. The game also features a “time‑attack” mode where players must score as many points as possible within 60 seconds; the score is then compared against the all‑time high‑score list stored on the cabinet’s internal memory. Operators can reset the high‑score table via a hidden menu accessed by holding the service button while powering on. For maintenance, the manual advises inspecting the sensor LEDs for proper illumination, as a dim LED indicates a misaligned sensor that may skew scoring. All scores are stored in the log.
Player Interaction Flow
When a player inserts a coin, the cabinet’s coin validator lights the attract‑mode LED and the game begins in attract mode. The player sees the jug spin on the display while the red LED indicators on the sensor module flash, signaling that the optics are ready. Pressing the start button triggers the conveyor belt to release a ball. The ball travels along the belt, passes the infrared sensor, and the LED turns off to confirm a successful detection. The jug then rotates to a random segment; if the ball lands in a scoring zone, the system adds the corresponding points to the player’s total. After each ball, the player can choose to continue by inserting another coin or end the session. The manual advises that the player should keep the sensor LEDs bright; a dim LED indicates a mis‑aligned sensor that could mis‑score. The flow also includes a bonus trigger: hitting the central segment activates a temporary multiplier, which the player sees on the display. Throughout the game, the player watches the score counter update in real time. When the player finishes, the cabinet displays the final score, offers a replay option, and resets the system for the next player. This sequence ensures a smooth, intuitive experience from coin insertion to final score display. The cabinet’s audio system plays a jaunty theme when the jug spins, and a chime signals each successful hit, enhancing the arcade atmosphere and keeping players engaged. Players can replay instantly by pressing the reset button now
