Abstract
Description
- The invention relates to a separation unit for sheet-like value documents in a sheet handling apparatus.
- Valuable documents such as bank notes are commonly separated one after the other from a horizontally oriented stack of documents. An example of such a separation apparatus is shown in US patent No. 5 657 981. In order to keep the size down of such a separation unit so that it does not consume valuable space, for example in different cash payment localities, it would be desirable if the documents could be separated directly from a vertically oriented stack inserted in a small opening of a unit having small small outer dimensions, such as a small top surface.
- An object of the invention is to provide a separation unit of the kind described above that may have small dimensions and swiftly, without any intermediate storage is capable of bringing the documents in the stack apart in a longitudinal direction.
- In an aspect of the invention, the separation unit has an infeed opening for receiving in the infeed unit a stack of the documents standing on edges of the documents, a separation channel for the documents following the infeed opening, an engagement surface in the separation channel for receiving the edges of the documents and forming an acute angle to a plane of the stack, first separation means opposite to the engagement surface in the separation channel for engagement with a lateral face of an adjacent document and for feeding said adjacent document with a first lower speed in the separation channel, and second separation means at a downstream distance from said first separation means for grasping the document and for feeding it with a second higher speed in the separation channel so that that the document is separated from the other documents in the stack.
- According to an embodiment of the invention, the separation channel is curved around a portion of the first separations means.
- The arresting means is suitably a piece of a thin-walled material having portions forming said bottom and said counter support. Thereby every document will be bent and pre-stressed by its inherent stiffness against the first separation means that thereby more positively feeds the document.
- The first separations means suitably comprises a feeding wheel having a free wheel function in a feeding direction to be entrained by the document when the document is fed by the second separation means.
- Other features and advantages of the invention will be apparent from the following detailed description.
-
- FIG. 1A-C are diagrammatic views of a broken away portion of an sheet handling apparatus according to the invention showing three steps during an infeed of a stack of sheets;
- FIGs. 2A-C are diagrammatic sectional views at a larger scale of a separation unit of the sheet handling apparatus according to FIG. 1 having interior parts exposed and being separating a sheet from the stack;
- FIG. 3 at a larger scale shows approximately the encircled area 3 of FIG. 1C; and
- FIG. 4 at a larger scale shows approximately the
encircled area 4 of FIG. 3 - FIG. 1A shows a sheet handling apparatus according to the invention generally designated by 10. The sheet handling apparatus 10 comprises an infeed
unit 20 for a stack of sheet-like value documents and cooperating with aseparation unit 50 adapted for fully bringing the documents in the stack apart from each other so that they thereafter can be further processed in ahandling unit 80 indicated by phantom lines. - As desired, the
handling unit 80 may, for example be adapted to identify, register, sort, intermediary store and outfeed the documents, for example bank notes of a varying kind and denomination. - The infeed
unit 20 has a vertical or a sloping infeedopening 22 for receipt of astack 12 ofdocuments 14. In FIG. 1A, the infeedopening 22 is shown delimited by a pair ofside end pieces stack 12 that is each time manually inserted in the infeedopening 22, the infeedopening 22 may have a constriction 22' at its input end. A pivotably movable arresting means 28 in the shape of a bent ― approximately to the character "2" shown on a seven segment display ― low-friction sheet metal plate, in a first position according to FIG. 1A at one end thereof forms a counter support or a bottom 30 for the lower end of the insertedstack 12. When the arrestingdevice 28 is pivoted clockwise about an axis 36 to a second position shown in FIG. 1B. the bottom will be removed, and a sliding and pushingsurface 32 in the vicinity of the other end of the sheet metal plate will form a counter support and push the insertedstack 12 of documents towards a feeding means in the shape of afeeding wheel 38 having afriction surface 40. - The
feeding wheel 38 has a surface having a reduced diameter over a large portion of its circumference so that it will not engage in the infeedopening 22 at an infeed position shown to FIG. 1. When thefeeding wheel 38 is rotated counter clockwise from the position of FIG. 1B, thefriction surface 40 is, however, brought to engagement with theadjacent document 14 of thestack 12. When thefeeding wheel 38 continues to rotate, thestack 14 is driven further down into theinfeed opening 22 to the position shown in FIG. 1C under influence of the counter spring force from the pushingsurface 32. In the position shown in FIG. 1C, the lower end of thestack 12 engages with a sloping engagement surface 54 (FIG. 1 C) of a supportingelement 52 of a friction increasing material, for example rubber, so that the bottom edges of the individual documents in thestack 12 will be displaced approximately in the manner that is further shown in FIGS. 3 and 4. - When the
feeding wheel 38 is rotated a bit further so that its radius decreases to thesurface 42 having the reduced diameter, thestack 12 is pushed back, in a manner not shown, to the right side of the infeedopening 22 by virtue of the pushingsurface 32. An ending flat surface of the sheetmetal arresting device 28 may then possibly form a higher bottom for a newly inserted stack of sheets. The feeding of thestack 12 down to and through theseparation unit 50, however, occurs so rapidly that the user in practice does not have enough time to insert a new stack in the infeed opening before all documents in the stack have left the infeedunit 20 and the arresting device has returned to the position of FIG. 1A. - When the
stack 12 is separated in the manner to be later described, the arrestingdevice 28 is pivoted back to the position of FIG. 1A so that the possibly present subsequent stack (not shown) drops downwards to the lower bottom 30. - FIGS. 2A-C illustrate the operation of the
separation unit 50 according to the invention. In FIG. 2A thelowest document 14 of thestack 12 has been fed forward a bit further into aseparation channel 66 of a pre-separating first separation means 56. The separation means 56 comprises a feeding orfriction wheel 58 having a relatively large diameter, freely journalled on adrive shaft 64, against whichfriction wheel 58 thelowest document 14 is in contact. A drive means 62 rigidly secured to thedriving shaft 64 is driving apin 60 protruding from the end face of thefeeding wheel 58 so that thewheel 58 rotates with a relatively small peripheral speed and strives to pull thelowest document 14. As is indicated in FIG. 2A, the next following document 14' may possibly be dragged forward a small distance in dependence of varying friction between the documents in thestack 12. - As is apparent from FIGs. 2A-2C, the
separation channel 66 is suitably curved along a portion of the circumference of thefeeding wheel 58 so that thedocument 14 by virtue of its inherent stiffness is forced against thefeeding wheel 58 to facilitate the feeding of the document in theseparation channel 66 - The
lowest document 14 that is fed by thefriction roller 58 at each occasion, is guided in theseparation channel 66 in a direction towards a second separation means 70 in the shape of a "roll nip" between a pair of contactingfeed rolls - When the leading edge of
document 14 reaches the fast rotatingfeed rolls separation unit 70, thedocument 14 is captured and is subjected to a jerk so that thedocument 14 ― roughly as in a so called "tablecloth trick" ― positively overcomes the friction of the adjacent document 14' so that this document stays in the stack. The freely joumalledfeeding wheel 58 can be allowed to be entrained almost a full turn by friction againstdocument 14, before the trailing edge ofdocument 14 leaves thewheel 58. Thefeeding wheel 58 preferably has such a large diameter that the trailing edge ofdocument 14 positively leaves thewheel 58 beforewheel 58 has completed the full turn by thepin 60 catching up the drive means 62 from behind. It is instead also conceivable to allow thefeeding wheel 58 being driven by a coupling having a freewheel function. It may then be driven by a still lower speed to allow the complete pulling apart of the documents in cooperation with thefeeding rolls - When the drive means 62 again catches up the
pin 60, the next document 14' will be sepa rated from thestack 12 in the manner described above until the complete stack is separated The possibly new stack 12' - In the handling unit 80 (FIG. 1) the
document 14 is advanced downstream the separatio apparatus by feeding means (not shown) having such an adjusted feeding speed that a de sired distance is maintained between the documents, for example a certain minimum dis tance between their adjacent edges. - In a manner not shown, the functions of the
infeed unit 20 and theseparation unit 50 can be initiated by, for example a photoelectric sensor in theinfeed opening 22 that signals to a cor trol unit to start and control the operation of respective drive motors (not shown) for the anresting device 28, thefeeding wheel 38 and the first and second separation means 56 an 70, respectively
