Abstract
Abstract The conveyor and collecting apparatus described obtains several advantages in conjunction with the controlled cooling of steel rod through transformation and the ultimate collection of the rod. The apparatus includes a first-level conveyor for passing steel rod immediately after rolling through a controlled cooling zone, where transformation occurs, and a second-level conveyor for receiving the transformed rod at the end of the first conveyor and for transporting the rod to a collecting apparatus. On both conveyors the rod is transported in the form of overlapping, non-concentric rings, although the rate of progression of both conveyors is not necessarily equal, and hence the degree of overlap of the rings may be different for each conveyor. The second conveyor includes means to vary the rate of transport of the rod rings, and also means to stop the conveyor operatively in conjunction with means to cut the rod.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
255 words
Controlled cooling and collecting apparatus for receiving hot rolled steel rod at a temperature above transformation, cooling said rod uniformly through transformation, and collecting said transformed rod in ring bundles, which comprises: a first-level conveyor including continuous rod-laying means for receiving steel rod immediately after rolling at a temperature above transformation and for depositing said rod on said firstlevel conveyor in the form of overlapping, non-concentric rings still at a temperature above transformation, and means for cooling said rod through transformation substantially uniformly throughout the length of said rod; a second-level conveyor, operative independently of said firstlevel conveyor, which second-level conveyor includes means for receiving transformed steel rod from said first-level conveyor in the form of overlapping, non-concentric rings and means for stopping the movement of said rod along the second-level conveyor; collecting means including means for receiving said rod at the downstream end of said second-level conveyor, means for serially advancing and dropping said rings, means for stopping said advancing rings, and means for collecting and forming said rod into ring bundles; and severing means operative in conjunction with said second-level conveyor for stopping the movement of said rod along said second-level conveyor and for stopping said advancing rings and having a positioning arm and shear, wherein said positioning arm is adapted to move a hanging rod portion of said rod when its movement is stopped into engagement with said shear; whereby, when said stopping means are operated the last of said advancing rings to drop assumes substantially an identical drop helix every time.
Claim 2
Dependent Claim
255 words
Controlled cooling and collecting apparatus for receiving hot rolled steel rod at a temperature above transformation, cooling said rod uniformly through transformation, and collecting said transformed rod in ring bundles, which comprises: a first-level conveyor including continuous rod-laying means for receiving steel rod immediately after rolling at a temperature above transformation and for depositing said rod on said firstlevel conveyor in the form of overlapping, non-concentric rings still at a temperature above transformation, and means for cooling said rod through transformation substantially uniformly throughout the length of said rod; a second-level conveyor, operative independently of said firstlevel conveyor, which second-level conveyor includes means for receiving transformed steel rod from said first-level conveyor in the form of overlapping, non-concentric rings and means for stopping the movement of said rod along the second-level conveyor; collecting means including means for receiving said rod at the downstream end of said second-level conveyor, means for serially advancing and dropping said rings, means for stopping said advancing rings, and means for collecting and forming said rod into ring bundles; and severing means operative in conjunction with said second-level conveyor for stopping the movement of said rod along said second-level conveyor and for stopping said advancing rings and having a positioning arm and shear, wherein said positioning arm is adapted to move a hanging rod portion of said rod when its movement is stopped into engagement with said shear; whereby, when said stopping means are operated the last of said advancing rings to drop assumes substantially an identical drop helix every time.
Claim 3
Dependent Claim
68 words
The controlled cooling and collecting apparatus of claim 1, wherein said means for advancing and dropping said rings includes tractor chains; and wherein said severing means includes a collecting tub and guide member for collecting rod rings in bundles and a horizontal plate movable into the collecting tub, when the movement of said rod is stopped, for positioning said hanging rod portion for engagement by said positioning arm.
Claim 4
Dependent Claim
86 words
The controlled cooling and collecting apparatus of claim 2, wherein engagement means are provided in conjunction with said means for stopping the movement of said rod along said second-level conveyor for engagement of said horizontal plate, positioning arm and shear, operative in sequence to stop said second-level conveyor, to advance said horizontal plate into said collecting tub, to move said positioning arm into contact with said hanging rod portion thereby advancing said rod into engagement with said shear, and to sever said rod with said shear.
Claim 5
Dependent Claim
280 words
Controlled cooling and collecting apparatus for receiving hot rolled steel rod at a temperature above transformation, cooling said rod uniformly through transformation, and collecting said transformed rod in ring bundles, which comprises: a first-level conveyor including continuous rod-laying means for receiving steel rod immediately after rolling at a temperature above transformation and for depositing said rod on said first-level conveyor in the form of overlapping, non-concentric rings still at a temperature above transformation, and means for cooling said rod thRough transformation substantially uniformly throughout the length of said rod; a second-level conveyor, operative independently of said first-level conveyor, which second-level conveyor includes means for receiving transformed steel rod from said first-level conveyor in the form of overlapping, non-concentric rings and means for stopping the movement of said rod along the second-level conveyor; collecting means including means for receiving said rod at the downstream end of said second-level conveyor and means for collecting and forming said rod into ring bundles; and severing means operative in conjunction with said second-level conveyor for stopping the movement of said rod along said second-level conveyor and having a positioning arm and shear, wherein said positioning arm is adapted to move a hanging rod portion of said rod when its movement is stopped into engagement with said shear; wherein said severing means includes (a) a collecting tub and guide member for collecting rod rings in bundles, (b) tractor chains for advancing the rod rings from the end of said second-level conveyor means to said collecting tub and (c) a horizontal plate movable into the collecting tub, when the movement of said rod is stopped, for positioning said hanging rod portion for engagement by said positioning arm.
