Abstract

Abstract An automatic sheet stacker for converting a continuous flow of sheared sheet metal pieces into predetermined size vertical stacks for further handling comprising a dolly platform having caster wheels with a fixed sidewall and a fixed end wall and a removable and adjustable side disposed on said fixed sidewall and adjustable toward and away from said fixed end wall. The removable and adjustable side wall is further provided with an adjustable guide which is slidable along said removable and adjustable side in a direction toward and away from said fixed sidewall. The fixed end wall is provided with an adjustable guide which is moveable toward and away from said fixed sidewall and slidably disposed on said fixed end wall. The dolly platform is further provided with biasing means or brake means for maintaining the dolly platform in a fixed position until released and moved to another position. The device is further provided with an attachment for stacking very small sheet metal segments.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 111 words
A stacking device for sheet material comprising: a flat dolly platform having a plurality of swivel caster wheels thereon; a first substantially vertical sidewall extending along one side of the platform and a first substantially vertical end wall extending along one end of said platform; a movable frame dispOsed on said platform to move in a direction toward and away from said end wall; a pair of substantially vertical horizontally adjustable guide members mounted on said frame and end wall respectively; for movement toward and away from said sidewall; and brake means extending below said platform for preventing movement of said device after it has been moved to a predetermined location.
Claim 2
Dependent Claim 111 words
A stacking device for sheet material comprising: a flat dolly platform having a plurality of swivel caster wheels thereon; a first substantially vertical sidewall extending along one side of the platform and a first substantially vertical end wall extending along one end of said platform; a movable frame dispOsed on said platform to move in a direction toward and away from said end wall; a pair of substantially vertical horizontally adjustable guide members mounted on said frame and end wall respectively; for movement toward and away from said sidewall; and brake means extending below said platform for preventing movement of said device after it has been moved to a predetermined location.
Claim 3
Dependent Claim 46 words
The device of claim 1 wherein said frame extends transversely of said platform, and said sidewall has a slide bar disposed therein and said frame has a hook assembly adapted to slide along said bar to adjust the distance of said frame from said end wall.
Claim 4
Dependent Claim 45 words
The device of claim 2 wherein said frame has a parallel slide bar, and a hook assembly is provided for sliding along said frame bar and one of said adjustable guide members is detachably connected to the frame hook assembly for movement toward said sidewall.
