Abstract
Abstract An apparatus and process of loading rolls of roofing material onto a stationary pallet, wherein the process performs a series of operations, in accordance with the present invention. Each operation includes the steps of: (a) loading rolls of roofing material onto an upwardly inclined conveyor; (b) depositing the rolls of roofing material onto a downwardly inclined-table; (c) dropping the rolls of roofing material onto a sloped, rotating table until the desired number of rolls of roofing material are accumulated; (d) rotating the table and then tilting the plate until it is nearly upright into a vertical position; (e) traversing the rotating table over the pallet conveyor; and (f) unloading the roll of roofing material from the rotating table onto the pallet.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
127 words
A process for loading rolls of roofing material onto a stationary pallet, wherein the process performs a series of operations, each operation comprising the steps of: (a) depositing a roll of roofing material onto a downwardly sloping first table; (b) dropping said roll of roofing material from said first table onto an upwardly sloping second table adjacent to said first table; (c) rotating said second table 90° within a plane defined by an upper surface of said second table; (d) tilting said second table to an unloading position where said plane is oriented substantially upright; (e) unloading the roll of roofing material from said second table onto said pallet, wherein the pallet is positioned stationary relative to the loading position of said second table throughout the process.
Claim 2
Dependent Claim
127 words
A process for loading rolls of roofing material onto a stationary pallet, wherein the process performs a series of operations, each operation comprising the steps of: (a) depositing a roll of roofing material onto a downwardly sloping first table; (b) dropping said roll of roofing material from said first table onto an upwardly sloping second table adjacent to said first table; (c) rotating said second table 90° within a plane defined by an upper surface of said second table; (d) tilting said second table to an unloading position where said plane is oriented substantially upright; (e) unloading the roll of roofing material from said second table onto said pallet, wherein the pallet is positioned stationary relative to the loading position of said second table throughout the process.
Claim 3
Dependent Claim
49 words
The process of claim 1 , wherein step (a) comprises loading a plurality of rolls of roofing material onto said first table in a juxtaposed position, step (b) comprises dropping a plurality of rolls of roofing material, and step (e) comprises unloading a plurality of rolls of roofing material.
Claim 4
Dependent Claim
15 words
The process of claim 1 , wherein said first table comprises a retractable stopping mechanism.
Claim 5
Dependent Claim
37 words
The process of claim 1 , wherein of the roll of roofing material is restrained during steps (c) and (d), thereby preventing the roll of roofing material from tipping in a direction away from the second table.
Claim 6
Dependent Claim
43 words
The process of claim 4 , wherein the roll of roofing material is restrained by a support member mounted on said second table and positioned above said roll of roofing material when said roll of roofing material is in a substantially vertical position.
Claim 7
Dependent Claim
49 words
The process of claim 1 , wherein the roll of roofing material is unloaded in step (e) by pushing a bottom portion of the roll of roofing material beyond a ledge mounted on said second table for supporting the plurality of rolls of roofing material in said vertical position.
Claim 8
Dependent Claim
47 words
The process of claim 6 , wherein the roll of roofing material is unloaded in step (e) by rotating a lever mechanism pivotally mounted on the table, wherein rotation causes the lever mechanism to push a bottom portion of the roll of roofing material beyond the ledge.
Claim 9
Dependent Claim
36 words
The process of claim 6 , wherein the roll of roofing material is unloaded in step (e) by pushing a bottom portion of the roll of roofing material along a roller rotatably mounted on the ledge.
Claim 10
Independent Claim
135 words
An apparatus for loading rolls of roofing material onto a stationary pallet, the apparatus comprising: (a) an upwardly inclined conveyor extending from a supply conveyor for supplying rolls of roofing material thereon; (b) a first downwardly sloping table for receiving said rolls of roofing material from said upwardly inclined conveyor; (c) an upwardly sloping second table adjacent to said first table; (d) a stop extending from said second table for supporting rolls of roofing material when oriented in a sloped position; and (e) a support member extending from said second table wherein a first plane is defined by an upper surface of said second table and when said first plane is oriented in a substantially upright position said support member prevents rolls of roofing material from tipping in a direction away from the second table.
Claim 11
Independent Claim
135 words
An apparatus for loading rolls of roofing material onto a stationary pallet, the apparatus comprising: (a) an upwardly inclined conveyor extending from a supply conveyor for supplying rolls of roofing material thereon; (b) a first downwardly sloping table for receiving said rolls of roofing material from said upwardly inclined conveyor; (c) an upwardly sloping second table adjacent to said first table; (d) a stop extending from said second table for supporting rolls of roofing material when oriented in a sloped position; and (e) a support member extending from said second table wherein a first plane is defined by an upper surface of said second table and when said first plane is oriented in a substantially upright position said support member prevents rolls of roofing material from tipping in a direction away from the second table.
Claim 12
Dependent Claim
46 words
The apparatus of claim 9 , wherein the support member includes a plate positioned contiguous to the upper surface edge of the second table, the plate defining a second plane which is generally perpendicular to said first plane defined by an upper surface of the table.
Claim 13
Dependent Claim
30 words
The apparatus of claim 9 , wherein the support member includes a lip extending from the plate in a direction generally parallel to the upper surface of the second table.
Claim 14
Dependent Claim
15 words
The apparatus of claim 9 , wherein the ledge has a roller rotatably mounted thereon.
Claim 15
Dependent Claim
50 words
The apparatus of claim 9 , further including a lever mechanism pivotally mounted on the second table, the lever mechanism having a pusher bar movable to a position extending through a slot formed in the second table to push a bottom portion of rolls of roofing material past the ledge.
Claim 16
Dependent Claim
20 words
The apparatus of claim 9 , wherein said downwardly sloping first table comprises a first end and a second end.
Claim 17
Dependent Claim
20 words
