Abstract
Abstract A bar handling and length determining apparatus cooperating with a bar shearing machine to cut predetermined lengths of bar stock, the apparatus comprising a powered conveyor apparatus rollingly supported on a frame track for striking engagement with strike members positionable at predetermined distances along the conveyor''s path. Disposed between the conveyor rollers at predetermined intervals are bar stop members selectively positionable in the path of the bar moved by the conveyor rollers. The combination of a selected bar stop member and a selected strike member determines the length of the bar from a determined point. Removal from the conveyor assembly is effected by pivotable lift arms located along the conveyor assembly, the lift arms selectively lifting the bar and sliding same into a selected bin alongside the conveyor assembly.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
286 words
A bar handling and length determining apparatus, comprising: a frame having a guide track; a conveyor assembly comprising: an elongated first side member having a first support track edge, and a plurality of in-line apertures; an elongated second side member having a second track support edge, the second side member disposed in spaced-apart parallel relationship to the first side member and having a plurality of in-line apertures, each aperture matingly aligned with one of the apertures of the first side member; a plurality of rollers disposed between the first and second side members, each roller having an axle bearingly mounted in an aperture of the first side member and the mating aperture of the second side member; rotating means rotating the rollers for moving bars along a path in the first direction; and, a strike plate; roller means disposed between the guide track of the frame and the support track edges of the first and second side members rollingly supporting the conveyor for movement in a first direction and in a second direction opposite to the first direction; a plurality of strike members reciprocatingly positionable in striking engagement with the strike plate, the strike members disposed at predetermined spaced-apart distances for selective positioning in the path of the strike plate for terminating movement of the power conveyor assembly in the first direction; select means positioning a selected strike member in the path of the strike plate; power means selectively moving the conveyor assembly in the first direction toward the strike members, and in the second direction away from the strike members; bar stop means selectively terminating movement of the bar in the first direction; and, bar removal means selectively removing the bar from the conveyor assembly.
Claim 2
Dependent Claim
286 words
A bar handling and length determining apparatus, comprising: a frame having a guide track; a conveyor assembly comprising: an elongated first side member having a first support track edge, and a plurality of in-line apertures; an elongated second side member having a second track support edge, the second side member disposed in spaced-apart parallel relationship to the first side member and having a plurality of in-line apertures, each aperture matingly aligned with one of the apertures of the first side member; a plurality of rollers disposed between the first and second side members, each roller having an axle bearingly mounted in an aperture of the first side member and the mating aperture of the second side member; rotating means rotating the rollers for moving bars along a path in the first direction; and, a strike plate; roller means disposed between the guide track of the frame and the support track edges of the first and second side members rollingly supporting the conveyor for movement in a first direction and in a second direction opposite to the first direction; a plurality of strike members reciprocatingly positionable in striking engagement with the strike plate, the strike members disposed at predetermined spaced-apart distances for selective positioning in the path of the strike plate for terminating movement of the power conveyor assembly in the first direction; select means positioning a selected strike member in the path of the strike plate; power means selectively moving the conveyor assembly in the first direction toward the strike members, and in the second direction away from the strike members; bar stop means selectively terminating movement of the bar in the first direction; and, bar removal means selectively removing the bar from the conveyor assembly.
Claim 3
Dependent Claim
39 words
The apparatus of claim 1 wherein the power means comprises: an extendable power cylinder having one end connected to the conveyor assembly and the other end connected to the frame; and, pneumatic means for selectively extending the power cylinder.
Claim 4
Dependent Claim
63 words
The apparatus of claim 2 wherein the bar stop means comprises: a plurality of bar stop members connected to the conveyor assembly and disposed at predetermined distances therealong, each bar stop member being selectively positionable in the path of the bar moved by the conveyor assembly; and, bar stop positioning means positioning a selected bar stop member in the path of the bar.
Claim 5
Dependent Claim
79 words
The apparatus of claim 3 wherein the bar removal means comprises: a plurality of lift arms pivotally supported by the conveyor assembly at predetermined distances therealong having a retract mode wherein the lift arms are in clearing relationship to the bar on the conveyor assembly and a lifting mode wherein the lift arms are selectively pivotable to raise the bar from the rollers; and, means for selectively pivoting the lift arms between the retract mode and the lifting mode.
Claim 6
Dependent Claim
106 words
The apparatus of claim 4 further comprising a bar cradle comprising: a plurality of stanchions positioned alongside of the conveyor assembly in lines normal thereto, the stanchions defining a plurality of bins therebetween and generally parallel to the conveyor assembly; and, a plurality of slide arms pivotally extending from the stanchions and cooperating to form a slide track with the lift arms in the lifting mode, the slide arms covering the bins in a down mode, and the slide arms selectively covering or opening the bins for bar admission thereto; and, slide arm power means selectively positioning the slide arms to cover or open the bins.
