Abstract

Abstract A switching device for interswitching the delivery of sheet-like articles conveyed to a bifurcation through a feed route, between the main and the branch routes, each route being formed of the opposing surfaces of a pair of endless belts, comprising, instead of the conventional wedge-shaped switching member disposed within the bifurcation, a switching member located outside the bifurcation. The device may be provided with means for rearranging the dislocated sheet-like matters, if any.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 124 words
A switching device for delivering sheet-like articles conveyed to a ramification through a feed route into a selected one of a plurality of routes, all said routes being disposed on a single plane, each of said routes beIng formed of a pair of driving wall members having opposing portions, each of said portions being substantially rectilinear in the direction perpendicular to said plane, and the outermost wall members of said plurality of routes being the extensions of the wall members of said feed route; said device comprising switching means for effecting delivery of each of said articles into a selected one of said plurality of routes, said switching means being completely positioned outside of said feed route, said plurality of routes and said ramification.
Claim 2
Dependent Claim 124 words
A switching device for delivering sheet-like articles conveyed to a ramification through a feed route into a selected one of a plurality of routes, all said routes being disposed on a single plane, each of said routes beIng formed of a pair of driving wall members having opposing portions, each of said portions being substantially rectilinear in the direction perpendicular to said plane, and the outermost wall members of said plurality of routes being the extensions of the wall members of said feed route; said device comprising switching means for effecting delivery of each of said articles into a selected one of said plurality of routes, said switching means being completely positioned outside of said feed route, said plurality of routes and said ramification.
Claim 3
Dependent Claim 25 words
A switching device as claimed in claim 1, wherein at least one of said extensions of the wall members is deformable inwardly at said ramification.
Claim 4
Dependent Claim 27 words
A switching device as claimed in claim 2, wherein said wall members are endless belts, and said opposing portions are the opposing surfaces of said endless belts.
Claim 5
Dependent Claim 135 words
A switching device as claimed in claim 3, wherein said ramification is a bifurcation, said plurality of routes is the main route and the branch route, said main route is the substantial extension of said feed route, and wherein said switching means is a swingable roller disposed outside said bifurcation in proximity to said extension of one of said belts which is the common belt for said feed and said main routes, said roller being operable between a first position wherein said one belt is not deformed inwardly when the selected route is said main route and a second position wherein said one belt is deformed inwardly of said bifurcation until said branch route becomes the substantial extension of said feed route, thereby directing said sheet-like articles to said main or said branch routes, respectively.
Claim 6
Dependent Claim 78 words
A switching device as claimed in claim 4, wherein detector means is disposed along said feed route for detecting the dislocation of said sheet-like articles, the predetermined one of said main and said branch routes is a feedback route for feeding the sheet-like articles delivered thereinto back to said feed route, and means is provided for positioning said roller, responsive to the discrimination made by said detector means, to direct the dislocated sheet-like articles to said feedback route.
Claim 7
Dependent Claim 114 words
A switching device as claimed in claim 5, wherein said roller positioning means causes said roller to direct the sheet-like articles to said feedback route when the spatial relation of the sheet-like articles passing said detector means is such that: a. the spacing between the corresponding edges of the last-mentioned sheet-like article and the sheet-like article conveyed adjacent thereto is not equal to a predetermined spacing, b. the last-mentioned sheet-like article overlaps at least at a portion the sheet-like article conveyed adjacent thereto; c. the last-mentioned sheet-like article is conveyed in slanted relation to said feed route, and d. the last-mentioned sheet-like article is conveyed along a misaligned path relative to said feed route.
Claim 8
Dependent Claim 70 words
A switching device as claimed in claim 2, wherein said switching means comprises at least one swingable roller disposed outside said ramification in proximity to said one extension of the wall members, said roller being adapted to deform said one extension of the wall members inwardly of said ramification to such an extent that the selected one of said plurality of routes becomes the substantial extension of said feed route.
