Abstract

Abstract An apparatus for transversely directing a roll, or log 10, from a work station 84 into a storage carrier 20 and for transversely unloading the log 10 from the carrier 20 onto the work station 84. The accumulator has a plurality of pivotally mounted storage carriers 20 which move along a path by the work station 84. A kicker assembly 86 transversely directs a log 10 into the path of a log carrier 20. A stationary stop 108 located adjacent that side of the log carrier 20 path that is away from the kicker assembly 86 deflects a directed roll so that it falls into the log carrier 20. A second stationary stop 106 is located adjacent the carrier path on the side of the carrier path that is closest to the kicker assembly 86 also deflects a directed roll into the log carrier 20. The apparatus for unloading a carrier includes a discharge pan 60, which is pivotally mounted so that it can be located between the work station 84 and the log carrier 20 path. As the log carriers 20 move in a discharge direction, a cam roller 30 mounted on the log carrier 20 contacts the surface 34 of a tilt cam 32 mounted in the accumulator. As the log carrier 20 continues to move in the discharge direction, the action of cam roller 30 against cam surface 34 causes the log carrier 20 to rotate and the roll 10 contained in log carrier 20b rolls out of the log carrier onto a rolldown surface 64 of the discharge pan 60 and onto the work station 84. Stop means 90a and 90b prevent a discharged log 10 from rolling away from the work station 84. Tilt cam 32 is pivotally mounted so that it can be retracted to a position such that cam surface 34 does not contact cam roller 30 when log carrier 20 is traveling in the accumulate direction. Similarly, discharge pan 60 is pivotally mounted so that it can be retracted to a position such that the edge 66 of the rolldown surface 64 does not extend into the path of the log carriers 20 when the log carriers 20 travel in the accumulate direction, and so that the rolldown surface 64 will not interfere with the loading of a log 10 into a log carrier 20 from the work station 84.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 174 words
An improved roll accumulator system having (a) means for moving a plurality of pivotally mounted storage carriers along a path by a work station, (b) a retractably mounted discharge pan located between the work station and the carrier path, said discharge pan in an unretracted position extending into the path and interfering with the travel of upright carriers, (c) means for rotating a storage carrier when it is near the discharge pan whereby a roll is caused to roll out of the carrier onto the discharge pan and then onto the work station, and (d) means for retracting the discharge pan out of the path of unrotated carriers, wherein the improvement comprises: (i) means operable when the discharge pan is retracted, for causing a roll at the work station to be transversely directed into the path of a carrier; and (ii) stationary stop means located adjacent that side of the carrier path that is away from the roll directing means, the stop means deflecting a directed roll so that it falls into a carrier.
Claim 2
Dependent Claim 174 words
An improved roll accumulator system having (a) means for moving a plurality of pivotally mounted storage carriers along a path by a work station, (b) a retractably mounted discharge pan located between the work station and the carrier path, said discharge pan in an unretracted position extending into the path and interfering with the travel of upright carriers, (c) means for rotating a storage carrier when it is near the discharge pan whereby a roll is caused to roll out of the carrier onto the discharge pan and then onto the work station, and (d) means for retracting the discharge pan out of the path of unrotated carriers, wherein the improvement comprises: (i) means operable when the discharge pan is retracted, for causing a roll at the work station to be transversely directed into the path of a carrier; and (ii) stationary stop means located adjacent that side of the carrier path that is away from the roll directing means, the stop means deflecting a directed roll so that it falls into a carrier.
Claim 3
Dependent Claim 34 words
An improved roll accumulator as recited in claim 1, the improvement further comprising stop means adjacent the work station for preventing a roll discharged from a carrier from rolling away from the work station.
Claim 4
Dependent Claim 34 words
An improved roll accumulator system as recited in claim 1 wherein the means for rotating the carrier comprises a cam surface mounted in the accumulator and a cooperating cam surface mounted on the carrier.
Claim 5
Dependent Claim 32 words
An improved roll accumulator system as recited in claim 1 wherein the means for rotating the carrier comprises a cam mounted in the accumulator and a cam roller mounted on the carrier.
Claim 6
Dependent Claim 33 words
A roll accumulator system as recited in claim 4 wherein the cam is retractably mounted, the improvement further comprising: (a) means for retracting the cam out of the path of the cam roller.
Claim 7
Dependent Claim 62 words
An improved roll accumulator system as recited in claim 1 further comprising: (a) a second stationary stop means located adjacent the carrier path on that side of the carrier path closest to the roll directing means, the second stop means preventing a directed roll from rolling out of the carrier and deflecting the directed roll so that it falls into a carrier.
