Abstract
A paper salvage attachment assembly of a paper cutter utilizes a horizontally reciprocable infeed conveyor assembly having an endless conveyor belt which fees bound products to a position beneath the cutting blade of a paper cutter assembly. An outfeed conveyor and stop bar assembly supports the bound product during severance of the spine from the found product. An adjustably positionable stop bar assembly is used to position the vertically reciprocable stop bar at a point downstream of the cutting blade to properly position the bound product so that only its spine will be severed. As the spine is out, the infeed conveyor assembly is retracted away from the paper cutter so that the severed spine may fall through the thus created gap and onto a scrap take away conveyor.
Claims11
A paper salvage attachment usable with a paper cutter having a reciprocable cutter blade and cooperating fixed cutting block and a clamp bar for holding a bound product during spine removal, said paper salvage attachment comprising:
- a reciprocating infeed conveyor assembly supported for reciprocable movement by support wheels which engage a support frame, said infeed conveyor assembly having an endless bound product infeed conveyor belt which passes about a cantilever frame end which is reciprocably positionable adjacent a first side of the cutting block of the paper cutter;
- an outfeed conveyor assembly positioned adjacent a second side of the cutting block of the paper cutter and including an endless outfeed conveyor belt
- a vertically reciprocable stop bar carried by a positional stop bar carriage assembly which is positioned above and across said outfeed conveyor belt, said stop bar being reciprocable to descend from said carriage assembly to block passage of a bound product along said outfeed conveyor belt during spine removal;
- means to reciprocate said infeed conveyor assembly toward and away from the paper cutter and including at least a first double acting cylinder affixed at a first end to said wheeled infeed conveyor assembly and at a second end to said support frame;
- and
- means to position said stop bar carriage assembly longitudinally along said outfeed conveyor belt with respect to the second side of the cutting block of the paper cutter to thereby longitudinally position said vertically reciprocable stop bar above said outfeed conveyor belt.
A paper salvage attachment usable with a paper cutter having a reciprocable cutter blade and cooperating fixed cutting block and a clamp bar for holding a bound product during spine removal, said paper salvage attachment comprising:
- an infeed conveyor assembly, said infeed conveyor assembly having an endless bound product infeed conveyor belt which passes about a cantilever frame end positionable adjacent a first side of the cutting block of the paper cutter;
- an outfeed conveyor and stop bar assembly positioned adjacent a second side of the cutting block of the paper cutter, said outfeed conveyor and stop bar assembly including a pair of spaced outfeed conveyor frame plates, an outfeed conveyor belt supported and driven by spaced outfeed drive and idler rollers extending between said outfeed conveyor frame plates, and a vertically reciprocable stop bar carried by a positionable stop bar carriage which includes a planar support frame having downwardly extending inner and outer guide flange pairs;
- an upwardly extending side plate secured to each of said spaced outfeed conveyor plates, said inner and outer guide flange pairs straddling said side plates, one of said outer guide flanges carrying a threaded bushing, said threaded bushing receiving a threaded lead screw driven by a lead screw drive motor affixed to said side plate being straddled by said bushing carrying outer guide flange and its cooperating inner guide flange, actuation of said lead screw drive motor causing said stop bar carriage to move relative to said spaced outfeed conveyor frame plates to position said stop bar carriage along said outfeed conveyor belt with respect to the second side of the cutting block of the paper cutter;
- and
- means to reciprocate said infeed conveyor assembly toward and away from the paper cutter.
