Bowling pin setting device

A positioning system (10) for bowling pins (1) comprising:

• a support frame (15),
• a plurality of levers (30), each of which is rotatably associated to the support frame (15), independently of one another according to an oscillating axis (X), in order to be able to oscillate between a rest position and a perturbed position,
• a plurality of cables (40), each comprising a first end (45) fixed to a respective pin (1) and a second end (50) fixed to a respective lever (30), wherein the respective lever is rotated to the perturbed position when the respective cable becomes entangled,
• a carriage (65) slidably associated to the support frame (15),
• a plurality of first guides (80) connected to the carriage (65), each configured for contacting a portion of a respective cable (40) comprised between the respective lever (30) and the respective pin (1),
• a positioning template (125), which is provided with a plurality of accommodating openings (130) for the pins (1), internally of each accommodating opening (130) a portion of a corresponding cable (40) being slidably inserted,
• a plurality of brakes (120), each of which is connected to the support frame (15), is associated to a respective cable (40) and is actuatable between a blocking position, in which the brake (120) retains the cable (40), and an unblocking position, in which the brake frees the cable (40),
• an electric motor (150) configured for activating the carriage (65) between a first position, wherein a distance between the carriage (65) and the plurality of levers (30) is maximum, and a second position, wherein a distance between the carriage (65) and the plurality of levers (30) is minimum,
• a plurality of sensors (175), each of which is associated to a corresponding lever (30) and is configured for detecting the position of the lever (30),
• a control unit (180) able to detect, via the plurality of sensors (175), the position of the plurality of levers (30) and to manage the electric motor (150) and the plurality of brakes (120),
• wherein the control unit (180) is configured to:
• activate the electric motor (150) to move the carriage (65) from the second position to the first position to raise the pins toward the positioning template,
• monitor the electrical absorption of the electric motor (150) during said movement of the carriage (65),
• identify, via the sensors (175), the position of the levers (30), if the monitored electrical absorption of the electric motor (150) exceeds a predetermined threshold to identify which cables have become entangled,
• activate into the blocking position the brakes (120) associated to the cables (40) fixed to the levers (30) that have been identified to be in the rest position, and,
• while keeping the activated brakes (120) in the blocking position, activate the electric motor (150) for moving the carriage (65) between the first position and the second position to raise and lower the pins fixed to the entangled cables until the carriage (65) reaches the first position and all the sensors (175) detect that the levers (30) are in the rest position.
