Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
112 words
A conveyor for the vertical transport of articles comprising a series of consecutively arranged sections, each section comprising a first pair of endless belts cooperating to form an upwardly moving run and a second pair of endless belts cooperating to form a downwardly moving run, switch means located between each of said successive sections selectively movable between a first position for permitting passage of said articles from one run to a corresponding run in the next section and a second position effecting transfer of said articles from the one run to the oppositely moving run of the same section, and means for operating said switch means in response to a predetermined signal.
Claim 2
Dependent Claim
112 words
A conveyor for the vertical transport of articles comprising a series of consecutively arranged sections, each section comprising a first pair of endless belts cooperating to form an upwardly moving run and a second pair of endless belts cooperating to form a downwardly moving run, switch means located between each of said successive sections selectively movable between a first position for permitting passage of said articles from one run to a corresponding run in the next section and a second position effecting transfer of said articles from the one run to the oppositely moving run of the same section, and means for operating said switch means in response to a predetermined signal.
Claim 3
Dependent Claim
27 words
The conveyor according to claim 1 wherein one of the belts in each of said first and second pairs of belts is common to both said pairs.
Claim 4
Dependent Claim
37 words
The conveyor according to claim 1 wherein said articles carry indicia thereon indicative of their destination and said switch means is provided with a sensor for determining said indicia and providing said signal for the operation thereof.
Claim 5
Dependent Claim
92 words
The conveyor according to claim 2 wherein said switch means comprises a rocker arm pivoted at one end adjacent an end of the run in the next section and a free end movable between said first and second positions, said free end facing the end of the associated run of the preceding section, said rocker arm being provided with an endless belt and means for driving said endless belt synchronously with the belts of the associated runs, thereby to interconnect said associated runs when said rocker arm is in said first position.
Claim 6
Dependent Claim
22 words
The conveyor according to claim 4 wherein said common belt includes means for directing said article into said opposite run when transferred.
Claim 7
Dependent Claim
48 words
The conveyor according to claim 1 including sensing means located in the oppositely directed run for determining the presence of an article therein and for providing a signal thereof, and means responsive to said signal for preventing the switching of said switch means to transfer another article therein.
Claim 8
Dependent Claim
31 words
The conveyor according to claim 1 including means for blocking movement of an article in said next turn when said switch means is in said second position to transfer said article.
Claim 9
Dependent Claim
27 words
The conveyor according to claim 5 wherein the ends of the sequentially aligned belts are shaped to provide enlarged funnellike passages for the transfer of said containers.
