How bowling balls come back
The function of maintaining the game rhythm and ensuring the convenience of the players is performed by the ball return system – pinspotters. This mechanical device lifts the ball after stopping the movement and moves it to a special stand. In addition, the structure sorts and positions the pins after a fall.
The pinspotter was invented by Gottfried Schmidt back in 1936. He was an employee of AMF, which even today holds a leading position in the bowling equipment market.
What are the characteristics of a ball return?
When choosing equipment for bowling, you should pay attention to its parameters. Ideally, it should have the following properties:
- Speed and fast access. The motor and control terminal, located above the track, speeds up the operation of the system and facilitates access to the elements of the mechanism;
- Spaciousness and power. The best option is a system with a strong engine, which simultaneously lifts up to five balls;
- Ball distribution system – each ball returns to its own track;
- Hand dryer – thanks to this attribute, players will not face the problem of balls slipping out of their hands.
What does the ball return system consist of?
Outwardly, the pinspotter resembles a loom, consisting of many shafts, motors and gears.
Bowling balls return equipment includes:
- Accelerator is an overclocking device. This part accepts and returns the ball to the player. He gets here immediately after the throw, and the accelerator allows him to gain the necessary speed. The advantage of this element is that the ball is not subject to any mechanical damage, because it does not come into contact with metal surfaces;
- Returner – bollift. The design raises and returns the ball to the accumulator located in the playing area;
- Ball position control sensors – they are used in modern versions of equipment.
The Pinsportter is powered by four separate electric motors that drive the distributor, sweeper, setting table and ball spreader. These elements are deliberately not combined into one power unit. Because the separation of functions between them helps to reduce wear on parts. And a defective small motor is easier to replace than one big one.
But, if everything is so mechanized: the balls quickly return to their tracks, and the pins line up quickly, then why don’t the players set record after record? In practice, other little things are also important, for example, the mass and diameter of the ball, the weight, which is indicated by a number on its surface.
