Conveyor apparatus for mutually independent pallets that carry bobbins or bobbin tubes

In a conveyor system for mutually independent pallets carrying bobbins or bobbin tubes, a conveyor apparatus, comprising a conveyor route, mutually independent pallets for carrying bobbins or bobbin tubes and having base plates, a moving surface for imparting a slaying force to said base plates standing on said moving surface and for slaving said base plates in a general conveying direction along said conveyor route by friction for a given first period of time, and means associated with said moving surface acting upon unmoving pallets for temporarily varying said slaving force of said moving surface for a given second period of time, said second period of time being substantially shorter than said first period of time, wherein said moving surface has a drive imparting a uniform motion to said moving surface, and said slaving force varying means are in the form of a control device acting upon said drive for superimposing a pulse-like motion upon said uniform motion of said moving surface.

In a conveyor system for mutually independent pallets carrying bobbins or bobbin tubes, a conveyor apparatus, comprising a conveyor route, mutually independent pallets for carrying bobbins or bobbin tubes and having base plates, a moving surface for imparting a slaving force of a given magnitude to said base plates standing on said moving surface and for slaving said base plates generally in one direction along said conveyor route by friction for a given first period of time, and means operatively associated with said moving surface for temporarily varying the magnitude of said slaving force of said moving surface for a given second period of time for shiftingly displacing said pallets relative to said moving surface, said second period of time being substantially shorter than said first period of time, wherein said moving surface has a drive imparting a uniform motion to said moving surface, and said slaving force varying means are in the form of a control device acting upon said drive for superimposing a pulse-like motion upon said uniform motion of said moving surface.

In a conveyor system for mutually independent pallets carrying bobbins or bobbin tubes, a conveyor apparatus, comprising a conveyor route, mutually independent pallets for carrying bobbins or bobbin tubes and having base plates, a moving surface for imparting a slaving force of a given magnitude to said base plates standing on said moving surface and for slaving said base plates generally in one direction along said conveyor route by friction for a given first period of time, and means operatively associated with said moving surface for temporarily varying the magnitude of said slaving force of said moving surface for a given second period of time for shiftingly displacing said pallets relative to said moving surface, said second period of time being substantially shorter than said first period of time, said force varying means including means for temporarily reversing a direction of travel of said moving surface during said given second period of time and immediately causing said moving surface to again move in the direction of travel.
