Abstract
A system of flight bars each flight bar having a leading component and a trailing component, a first pair of endless driving elements interconnected with each leading component and a second pair of spaced apart endless driving elements interconnected with each trailing component. Controlled relative movement is imparted to the first and second pair of endless driving elements so as to vary the distance between the trailing component of a flight bar and the leading component of an immediately succeeding flight bar thereby to render the system adaptable for use in conjunction with packages of different horizontal dimensions in the direction of movement of the flight bars.
Claims13
A system including flight bars for advancing packages in sequence along a predetermined path each of said flight bars having a leading component and a trailing component, a first pair of spaced apart endless driving elements interconnected with each of said leading components and a second pair of spaced apart endless driving elements interconnected with each of said trailing components, said first and said second pairs of endless driving elements being movable in synchronism so as to impart movement to packages along said predetermined path, means for imparting controlled relative movement to said first and said second pairs of endless driving elements so as to vary the distance between the trailing component of a flight bar and the leading component of an immediately succeeding flight bar thereby to render the system adaptable for advancing packages of different horizontal dimensions in the direction of movement of the flight bars along said predetermined path, and characterized by means for interrelating said leading and trailing components to accommodate relative movement therebetween within a predetermined range, an end plate pivotally connected with each of said flight bar leading components near each end thereof and a pin secured to each of said trailing components near each end thereof and wherein each of said end plates includes a slot in which the adjacent pin is slidably disposed.
A system including flight bars for advancing packages in sequence along a predetermined path each of said flight bars having a leading component and a trailing component, a first pair of spaced apart endless driving elements interconnected with each of said leading components and a second pair of spaced apart endless driving elements interconnected with each of said trailing components, said first and said second pairs of endless driving elements being movable in synchronism so as to impart movement to packages along said predetermined path, and motive means including a driving motor, interconnected with linkage means and with a gear box having rotatable input and output shafts, said output shaft being connected with said linkage means, and means for securing said input shaft against rotation thereby to cause said linkage means to maintain synchronous movement of said pairs of endless driving elements so as to prevent undesired changes in the space relations of said flight bars.
A system including flight bars for advancing packages in sequence along a predetermined path each of said flight bars having a leading component and a trailing component, a first pair of spaced apart endless driving elements interconnected with each of said leading components and a second pair of spaced apart endless driving elements interconnected with each of said trailing components, said first and said second pairs of endless driving elements being movable in synchronism so as to impart movement to packages along said predetermined path, means for imparting controlled relative movement to said first and said second pairs of endless driving elements so as to vary the distance between the trailing component of a flight bar and the leading component of an immediately succeeding flight bar thereby to render the system adaptable for advancing packages of different horizontal dimensions in the direction of movement of the flight bars along said predetermined path, and means for interconnecting said leading and trailing components with each other to limit relative movement therebetween within a predetermined range.
