A pinsetter is the essential machine used in bowling alleys to automatically reset the pins after each roll. Before its invention, pinboys manually reset the pins, making the game slower and more labor-intensive. Today, modern bowling pinsetters operate with precision, allowing for smooth gameplay.
Understanding the parts of a pinsetter can help bowling enthusiasts, alley owners, and technicians appreciate the complexity of this machine. This guide breaks down the key components of a pinsetter, their functions, and how they work together to keep the game running efficiently.
1. What Is a Pinsetter?
A pinsetter is an automated device that picks up fallen pins, resets them in their correct positions, and returns the ball to the player. Different types of pinsetters exist, such as those used for ten-pin, duckpin, and candlepin bowling, but they all share similar core components.
2. Main Parts of a Pinsetter and Their Functions
2.1 Pin Table
The pin table holds the bowling pins in place before and after they are reset. It ensures that the pins are positioned correctly and aligned according to standard bowling regulations.
2.2 Pin Elevator
The pin elevator is responsible for lifting fallen pins from the pit and transporting them to the pin distributor. This system typically consists of grippers or conveyor belts that securely hold the pins while moving them upward.
2.3 Pin Distributor
Once the pins reach the top of the machine, the pin distributor sorts and organizes them. It directs each pin to its correct position on the pin table, ensuring a smooth reset process.
2.4 Pin Deck
The pin deck is the area on the lane where the pins are arranged in a triangular formation. The pinsetter lowers the pins onto this deck after sorting them.
2.5 Pin Holder (Pin Grippers)
Many pinsetters use grippers or clamps to hold the pins in place before resetting them onto the lane. This ensures that the pins do not fall prematurely or shift out of alignment.
2.6 Sweep Bar (Sweeper Arm)
The sweep bar, also called the sweeper arm, is responsible for clearing fallen pins from the lane after a player rolls the ball. This prevents obstructions and ensures that the lane is clean for the next roll.
2.7 Ball Return System
After a player rolls the ball, the ball return system transports it back to the player. This system usually consists of a conveyor belt, rollers, or an elevator that lifts the ball and sends it down the return track.
2.8 Pit Cushion and Backstop
The pit cushion absorbs the impact of fast-moving bowling balls and fallen pins. The backstop helps keep everything contained within the machine, preventing damage and reducing noise.
2.9 Pin Sensing System
Modern pinsetters use sensors and cameras to detect which pins have been knocked down. This technology helps automate the scoring process and ensures that the correct pins are reset.
2.10 Control Panel and CPU
The control panel and CPU (central processing unit) are the brains of the pinsetter. They control all the machine’s movements, ensuring it operates efficiently. Many modern pinsetters are programmed with automatic adjustments to improve accuracy.
3. How a Pinsetter Works Step by Step
-
Detection of Pins – The machine identifies which pins have fallen using sensors.
-
Sweep Action – The sweep bar clears any knocked-down pins from the lane.
-
Pin Elevator Movement – Fallen pins are lifted by the pin elevator to the distributor.
-
Pin Sorting and Placement – The pin distributor arranges the pins and prepares them for resetting.
-
Ball Return – The ball is transported back to the player via the ball return system.
-
Pin Resetting – The pin table places the pins back onto the pin deck, ready for the next roll.
4. Types of Bowling Pinsetters
4.1 Free-Fall Pinsetters
These are older mechanical pinsetters that drop pins freely onto the lane. They require more maintenance but are still used in some traditional bowling alleys.
4.2 String Pinsetters
String pinsetters use thin strings attached to each pin, making resetting faster and reducing the chance of misplaced pins. They are commonly used in smaller bowling centers and home bowling lanes.
4.3 Fully Automated Pinsetters
Modern bowling alleys use fully automated pinsetters that incorporate computerized controls, sensors, and AI-driven adjustments for greater accuracy and efficiency.
5. Maintenance and Common Issues
5.1 Regular Cleaning and Lubrication
-
Dust and dirt can clog the moving parts, so regular cleaning is essential.
-
Lubricating moving components ensures smooth operation and reduces wear.
5.2 Checking Sensors and Electronics
-
If the pin detection system malfunctions, it may fail to reset correctly.
-
Technicians should check the wiring and software settings regularly.
5.3 Adjusting the Sweep Arm
-
If the sweep arm is misaligned, it may leave fallen pins behind.
-
Proper adjustments ensure efficient clearing of the lane.
5.4 Inspecting the Ball Return System
-
Slow or stuck ball returns can disrupt gameplay.
-
Cleaning the rollers and ensuring proper alignment can prevent issues.
6. Fun Facts About Pinsetters
-
The first automatic pinsetter was invented by Gottfried Schmidt and introduced by Brunswick in 1956.
-
A modern pinsetter can reset all 10 pins in less than 9 seconds.
-
Pinsetters handle over 100,000 pins per year in a busy bowling alley.
-
The loud clanking noise you hear after a roll comes from the pins hitting the backstop and the sweeper clearing the lane.
The pinsetter is a fascinating and essential part of every bowling alley. It ensures a seamless bowling experience by quickly resetting pins, returning the ball, and keeping the game moving. Understanding its key parts and functions can help bowling enthusiasts appreciate the technology behind the sport.
Whether you’re a casual bowler or someone working in the industry, knowing how a bowling pinsetter works adds a deeper level of appreciation for this complex and efficient machine.
