Open the CIPO recordAbstract From the Canadian patent
An improved automatic bottle filling apparatus is provided. The apparatus includes a spring loaded back pressure plate which avoids jamming of bottles that are carried by a conveyor. A bottle detection system comprising a photoelectric device or microswitch assures positioning and detection of an individual bottle. Vibration is essentially dampened by guide plates riding on the vertical columns. Overheating of the drive motors to operate the vertical movement is obviated by use of a pair of continuously operated motors running in opposite directions connected to mechanical actuators and by means of clutch brake mechanisms.
