Automatic machine for filling and closing flasks or the like containers

An automatic machine for filling and closing of containers having necks and bodies comprising:

• a supply means for supplying containers to be filled in a single file, one at a time, and in a synchronous manner;
• a first transfer carousel having a series of adjustable neck holding grippers which respectively grip by the neck and thus receive each successive container from said supply means;
• a filling carousel in which the containers are filled having a series of adjustable body holding grippers which respectively grip by the body and thus receive each successive container from said first transfer carousel, said filling carousel also having a respective filler associated with each said body holding gripper for filling the container held thereby;
• a second transfer carousel having a series of adjustable neck holding grippers which respectively grip by the neck and thus receive each successive container from said filling carousel;
• a sealing carousel in which the containers are sealed having a series of adjustable body holding grippers which respectively grip by the body and thus receive each container from said second transfer carousel;
• a transport means which respectively receives each container from said sealing carousel for transporting the containers away from said sealing carousel, said transport means including a means for sorting correctly filled and sealed containers from containers which are not correctly filled and sealed;
• a progressive weighing and sampling means for selectively determining tare and gross weights of successively selected ones of the containers filled by each of said fillers, said sampling means including
• a first weighing means for determining a tare weight of a selected container,
• a first sample carousel having an adjustable body holding gripper which periodically grips a selected container from said first transfer carousel and delivers the selected container to said first weighing means, and which then grips the selected container after weighing and delivers the selected container to a predetermined said gripper of said first transfer carousel,
• a first synchronizing means for causing said supply means to have an empty spot in the single file of containers when the predetermined said gripper of said first transfer carousel gripping the selected container passes said supply means,
• a second weighing means for determining a gross weight of the selected container after filling,
• a second sample carousel having an adjustable body holding gripper which periodically grips the selected and now filled container from said second transfer carousel and delivers the selected container to said second weighing means, and which then grips the selected container after weighing and delivers the selected and now filled container to a predetermined gripper of said second transfer carousel,
• a second synchronizing means for causing said predetermined said gripper of said second transfer carousel to be open and empty when said holding gripper of said second sample carousel delivers the selected container thereto, and
• a recording means for recording the tare and gross weights of each successively selected container for each said filler.
