Method and system for controlling bowling ball return device

Abstract

A method for controlling a bowling ball return device comprises following steps: detecting, by using one or more sensors, an obstruction inside the bowling ball return device in vicinity of an accelerator belt, turning off, by using processing circuitry, a motor of the accelerator belt of the bowling ball return device and closing, by using the processing circuitry, bowling lanes coupled with the bowling ball return device.

1 . A method for controlling a bowling ball return device, comprising:
 detecting, by using one or more sensors, an obstruction inside the bowling ball return device in vicinity of an accelerator belt;   turning off, by using processing circuitry, a motor of the accelerator belt of the bowling ball return device; and   closing, by using the processing circuitry, bowling lanes coupled with the bowling ball return device.   
     
     
         2 . The method according to  claim 1 , wherein the bowling lanes coupled with the bowling ball return device are closed by a boom. 
     
     
         3 . The method according to  claim 1 , wherein an alarm is generated when detecting the obstruction inside the bowling ball return device. 
     
     
         4 . The method according to  claim 3 , wherein the alarm is shown in a control unit of the bowling ball return device. 
     
     
         5 . The method according to  claim 4 , wherein the alarm comprises information about the obstruction. 
     
     
         6 . The method according to  claim 1 , wherein the one or more sensors are further configured to detect a state of ball doors of the bowling ball return device. 
     
     
         7 . The method according to  claim 1 , wherein the one or more sensors are configured to detect the obstruction in a first ball entrance and a second ball entrance. 
     
     
         8 . The method according to  claim 1 , wherein the one or more sensors comprises an ultrasonic sensor. 
     
     
         9 . The method according to  claim 1 , wherein the one or more sensors are capable of recognizing a pin in the bowling ball return device. 
     
     
         10 . A system for controlling a bowling ball return device, the system comprising:
 one or more sensors configured to detect an obstruction inside the bowling ball return device in vicinity of an accelerator belt; and   a processing circuitry configured to turn off a motor of the accelerator belt of the bowling ball return device, and to close bowling lanes coupled with the bowling ball return device.   
     
     
         11 . A system for controlling a bowling ball return device, the system comprising:
 one or more sensors configured to detect an obstruction inside the bowling ball return device in vicinity of an accelerator belt; and   a processing circuitry configured to turn off a motor of the accelerator belt of the bowling ball return device, and to close bowling lanes coupled with the bowling ball return device;   wherein the system is configured to perform the steps of  claim 1 .
