Abstract
Abstract A conveyor assembly which receives two lines of adjoining boxes, then separates the boxes in spaced relation, and finally combines the two lines into a single line by alternate interposition. Boxes having the same size may be combined by a mechanical control. Boxes of varying sizes may be combined by a crossconnected control means using a photosensitive detector, stopping one line of boxes as long as the other photosensitive detector is blocked.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
253 words
A merging conveyor system for joining two lines of articles into a single line by alternate transfer comprising: a. a first conveyor Unit including a plurality of transversely mounted spaced rods with means for moving the rods toward a delivery position; b. a plurality of carrier bases slidably mounted on the rods for carrying articles, each of said bases including a cam follower rod extending below the rod plane; c. cam means under the rods for engaging the cam followers to merge the bases when they are carrying articles and to separate the bases in alternate sequence when the bases are moving toward a carry position; d. a second conveyor unit adjoining the first unit for delivering articles to the first conveyor in two lines, the articles in each line spaced from each other by a distance which is more than the length of the articles; e. a third conveyor unit mounted for delivering articles to the second conveyor in two lines, said third conveyor moving at a speed which is appreciably less than the speed of the second conveyor for increasing the article spacing on the second conveyor; f. a stop arm system mounted on each side of the second conveyor for stopping the motion of the article lines until a nonconflicting spacing between the articles is realized; and g. a photosensitive sensing system for each of said lines coupled to a solenoid and a stop arm for stopping one line of articles when an article is sensed on the other line.

Claim 3
Dependent Claim
37 words
A conveyor system according to claim 1 wherein said rods are moved toward a delivery position by two chains secured to the ends of the rods, and by a pair of sprocket wheels coupled to the chains.
Claim 4
Dependent Claim
74 words
A conveyor system according to claim 1 wherein a first half of said carrier bases have their cam follower rods offset toward one side of the conveyor to engage a first merging cam, and wherein the second half of said carrier bases have their cam follower rods offset toward the other side of the conveyor to engage a second merging cam, said first and second bases disposed alternately along the length of the conveyor.
Claim 5
Dependent Claim
50 words
A conveyor system according to claim 1 wherein each of said stop arm systems include a stop arm, a first solenoid for moving the stop arm into article engaging position, a mechanical latch for holding the stop arm in engaging position, and a second solenoid for engaging the stop arm.
