In the previous article, we explored the differences between the two machines in terms of pin handling and lifting mechanisms. Now, let's examine how the pins are processed after being lifted to the top of the machines and how they ultimately return to their original spots on the pin deck.
After being lifted, the pins need to be accurately distributed to 10 preset positions. The Pin Distribution and Setting Mechanisms test the machine's spatial planning and fault tolerance.
Brunswick GSX Pin Distribution and Setting Mechanisms:
Its distribution system functions like an "intelligent transportation hub":
The top distributor includes a Shark assembly, four feed lanes, two crossing lanes, ten pin stations, and two Outflow Chutes.
After pins roll from the elevator to the distributor, they are guided by the Shark Fin assembly to feed different lanes, enabling flexible distribution of pin stations.
If a lane's pin stations are full, excess pins automatically flow into the outflow chutes and eventually fall into the bottom ball pit, waiting to be lifted again.
Usually, each machine has at least 22 pins to ensure 10 are always ready. If no one bowls within 1 minute, the distributor will shut down to save power.
Each pin is equipped with a Pin Release Lever at its base. When a set of pins is ready, the release levers simultaneously release the pins, which fall into 10 corresponding Pin Holders on the lower Setting Table and are secured by two Pin Grippers—this is the final phase that places the pins on the lane.
The setting table is equipped with a swing axis. When the setting table descends, the pins are rotated 90 degrees by the swing axis, and each pin holder opens to release the 10 pins, completing the pin setting process.
For pins not hit on the first throw, the setting table descends, and the Spotting Tongs pick up the remaining pins. Once the lane is ready, the pins are accurately returned to their original positions.
Qubica AMF 82-90XL adopts a "point-to-point" direct delivery scheme:
The top distributor directly distributes pins to 10 individual positions, each corresponding to a Pin Cup.
When a set of pins is ready, a device called the Shuttle lowers the pin cups as a whole to align with the pin cups on the setting table. The pins are then precisely placed in their designated positions on the pin deck by rotating the pin cups.
Based on what we've learned about the two machines'pin handling, lifting mechanisms, and pin distribution:
1. Brunswick GSX trades a complex structure for high fault tolerance, but its intricate mechanical design leads to higher maintenance costs.
2. Qubica AMF 82-90XL advantages lie in its relatively simple mechanical structure with fewer moving parts than the GSX, which theoretically reduces maintenance complexity. However, in actual bowling alley operations, this simplicity places higher demands on equipment precision—requiring millimeter-level accuracy not only in pin grabbing and lifting but also in subsequent pin distribution. Furthermore, technical requirements for technicians of Qubica AMF 82-90XL will also be higher. This explains why the AMF 82-90XL requires more frequent calibration.
The choice should be made based on comprehensive considerations of bowling alley size, budget, and technical reserves. After all, the pinsetter that best fits one's operational needs is the true "efficient worker," delivering visible, flawless service behind the scenes.
