Abstract
Abstract A material handling device comprises a roller conveyor component having rollers which are separated by gaps; a cage component which includes rows of uprights, the spacing and the thickness of the uprights in each row being such as to permit their insertion into said gaps and their movement through the gaps; crosspieces interconnecting the uprights of one row only with corresponding uprights of other rows, the crosspieces extending parallel to the axes of the rollers and being insertable in the gaps; a motor for effecting relative movement between the cage and the conveyor perpendicularly to each other such that the uprights and the crosspieces can move through the gaps.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
108 words
A material handling device comprising a roller conveyor component having rollers which are separated by gaps; a cage component which includes rows of uprights, the spacing and the thickness of the uprights in each row being such as to permit their insertion into said gaps and their movement through said gaps; crosspieces interconnecting the uprights of one row only with corresponding uprights of other rows, said crosspieces extending parallel to the axes of said rollers and being insertable in said gaps means for effecting relative movement between said cage and said conveyor perpendicularly to each other such that said uprights and said crosspieces can move through said gaps.
Claim 2
Dependent Claim
108 words
A material handling device comprising a roller conveyor component having rollers which are separated by gaps; a cage component which includes rows of uprights, the spacing and the thickness of the uprights in each row being such as to permit their insertion into said gaps and their movement through said gaps; crosspieces interconnecting the uprights of one row only with corresponding uprights of other rows, said crosspieces extending parallel to the axes of said rollers and being insertable in said gaps means for effecting relative movement between said cage and said conveyor perpendicularly to each other such that said uprights and said crosspieces can move through said gaps.
Claim 3
Dependent Claim
36 words
A material handling device according to claim 1, wherein said crosspieces extending between corresponding uprights form an array, each crosspice of one array having corresponding crosspieces in other arrays lying at the same level with it.
Claim 4
Dependent Claim
44 words
A material handling device according to claim 2, wherein each crosspiece of one array has corresponding crosspieces in all other arrays lying at the same level with it to form an order of crosspieces, each order constituting a support for a group of articles.
Claim 5
Dependent Claim
25 words
A material handling device according to claim 1, wherein the cage component comprises a frame, said uprights being fastened by one end to said frame.
Claim 6
Dependent Claim
51 words
A material handling device according to claim 4, wherein said frame includes two parallel interconnected, spaced apart beams, the uprights being fastened to each beam by one end thereby forming two parallel rows of uprights and the crosspieces thereby forming supports of a width equalling the distance between said two rows.
Claim 7
Dependent Claim
15 words
A material handling device according to claim 4, wherein said frame is provided with wheels.
Claim 8
Dependent Claim
44 words
A material handling device according to claim 1, wherein the means for effecting relative movement between said cage and said conveyor includes sensor means to interrupt said relative movement each time one order of crosspieces reaches the level of said gaps of said conveyor.
Claim 9
Dependent Claim
160 words
Apparatus for handling articles comprising a roller conveyor component having rollers which are separated by gaps; a cage component including a plurality of rows of uprights, the rows extending in the direction of said conveyor component and the spacing and thickness of the uprights in each row being such as to permit said uprights to move into and through said gaps; means for effecting relative movement between said uprights and said roller conveyor component in a direction perpendicular to the axes of the rollers so that said uprights can be moved through said gaps; nd article-supporting means carried by said uprights for receiving articles from or depositing articles on said rollers when said relative movement is effected, said shape, dimensions and arrangement of said article-supporting means allowing the latter to pass through said gaps and said article supporting-means being arranged in arrays one above another such that each array is capable of receiving or depositing a respective group of articles.
Claim 10
Dependent Claim
160 words
Apparatus for handling articles comprising a roller conveyor component having rollers which are separated by gaps; a cage component including a plurality of rows of uprights, the rows extending in the direction of said conveyor component and the spacing and thickness of the uprights in each row being such as to permit said uprights to move into and through said gaps; means for effecting relative movement between said uprights and said roller conveyor component in a direction perpendicular to the axes of the rollers so that said uprights can be moved through said gaps; nd article-supporting means carried by said uprights for receiving articles from or depositing articles on said rollers when said relative movement is effected, said shape, dimensions and arrangement of said article-supporting means allowing the latter to pass through said gaps and said article supporting-means being arranged in arrays one above another such that each array is capable of receiving or depositing a respective group of articles.
Claim 11
Independent Claim
115 words
A method of removing articles from or depositing articles on a roller conveyor having rollers which are spaced apart by gaps, said method comprising inserting into each of a plurality of adjacent gaps at least two uprights which are spaced apart along the length of the respective gap, said at least two uprights carrying article-supporting means; and effecting relative movement between said conveyor and all said uprights and article supporting-means in a direction perpendicular to the axes of the rollers so as to effect movement of the uprights and article-supporting means through the gaps whereby articles will be lifted from the rollers or deposited on the rollers depending on the direction of said relative movement.
Claim 12
Independent Claim
115 words
A method of removing articles from or depositing articles on a roller conveyor having rollers which are spaced apart by gaps, said method comprising inserting into each of a plurality of adjacent gaps at least two uprights which are spaced apart along the length of the respective gap, said at least two uprights carrying article-supporting means; and effecting relative movement between said conveyor and all said uprights and article supporting-means in a direction perpendicular to the axes of the rollers so as to effect movement of the uprights and article-supporting means through the gaps whereby articles will be lifted from the rollers or deposited on the rollers depending on the direction of said relative movement.
Claim 13
Dependent Claim
38 words
A method as in claim 9 wherein said movement is effected in a mode to deposit the articles on the rollers and wherein said rollers are thereafter rotated so as to transfer the articles away from the uprights.
Claim 14
Dependent Claim
21 words
A method as in claim 9 wherein said movement is effected in a mode to deposit the articles on the rollers.
