Abstract
A singulator for feeding documents one at a time onto the transport of a processing machine. The singulator includes a pick-off means and a stripper means for preventing multi-feeds of documents. The stripper means is comprised of two independent stripper assemblies which are mounted one above the other. Each assembly is comprised of an arm which is rotatably mounted to the machine at one end and which has a means at the other end for engaging any multi-fed documents. Each stripper assembly has basically the same structure except the arm of one stripper assembly is shorter than the arm of the other assembly whereby the assemblies contact a multi-fed document at different points.
Claims15
A singulator for feeding single documents from a stack of documents, said singulator comprising:
- a pick-off means for picking off a single document from said stack of documents;
- and
- stripper means for engaging any additional document removed from said stack with said single document, said stripper means comprising:
- a first stripper assembly and a second stripper assembly mounted one over the other and substantially parallel to each other for independent rotation about a common pivot point;
- said first stripper assembly comprising:
- a first arm having a first end rotatably mounted at said common pivot point and having means at a second end for engaging and restricting further movement of said additional document with respect to said single document;
- and wherein said second stripper assembly comprises:
- a second arm having a first end rotatably mounted at said common point and having means at a second end for further engaging and restricting further movement of said additional document with respect to said single document wherein said first arm is of a shorter length than that of said second arm whereby said first stripper assembly will engage said additional document before said second stripper assembly engages said additional document.
A document feeder for a document processing machine, said feed comprising:
- a deck having a magazine thereon;
- said magazine adapted to receive a stack of documents;
- a pick-off means for picking off documents one at a time from said stack of documents, said pick-off means comprising:
- a pick-off roller for engaging the first document of said stack of documents;
- and
- means for driving said pick-off roller in a forward direction to engage said first document and move said first document towards a transport;
- and
- stripper means for engaging any additional document removed with said first document to prevent further movement of said additional document, said stripper means comprising:
- a first stripper assembly and a second stripper assembly mounted one over the other and substantially parallel to each other for independent rotation about a common vertical pivot point on said deck;
- said first stripper assembly comprising:
- a first arm having a first end rotatably mounted at said common pivot point on said deck and having means at a second end for engaging and restricting further movement of said additional document with respect to said single document;
- and wherein said second stripper assembly comprises:
- a second arm having a first end rotatably mounted at said common point on said deck and having means at a second end for further engaging and restricting further movement of said additional document with respect to said single document wherein said first arm is of a shorter length than that of said second arm whereby said first stripper assembly will engage said additional document before said second stripper assembly engages said additional document.
