Abstract
A platen structure to facilitate the transport of stacked sheet material conveyed along a transport deck of a sheet feeing apparatus. The platen structure comprises first and second segments connected by means of a compliant coupling. The first segment of the platen is operative to engage a face of the stacked sheet material and apply a stabilizing normal force thereon. The second segment of the platen is operative to engage and travel synchronously with a moving surface of the transport deck. Furthermore, the first and second segments are connected by means of a compliant coupling which is operative to facilitate the relative angular displacement of the first and second segments about at least one axis while maintaining the relative linear displacement therebetween about at least one of the other axes. The platen structure ensures reliable sheet material run-out by compensating for a reduction in sheet material weight as the final or last sheets of the stack are singulated/separated. Furthermore, the compliant coupling enables the various segments of the platen structure to conform to the contour of the stacked sheet material, i.e., a cantilevered delivery profile.

The specific embodiment
Narration sheet conveyance apparatus of the present invention in the scope of mail inserter system, but, should be appreciated that the present invention can be applicable to wherein for subsequently processing or process all sheet materials must be separated or be divided into individual any sheet conveyance apparatus.Using sheet conveyance apparatus for the purpose of making/produce mail only is that an exemplary embodiment is shown, and should explain principle of the present invention widely with the viewpoint of the appended claims of this specification sheets.
Fig. 1 and Fig. 2 show respectively according to the top perspective view of cut sheet feeder 10 of the present invention and lateral plan, and this forwarder comprises horizontal feed platform 12 and inclination transport platform 14, transmits and support platform 16 and be configured to and transmit the plenum chamber 18 that support platform 16 combines.Level and inclination transport platform 12,14 comprise transfer system 20, promptly are generally by being arranged on all belt wheel (not shown) structural support under this and the belt conveyor or the chain 22 of transmission, are used for along platform 12,14 feeding sheets.
Before operation and advantage that cut sheet feeder 10 is discussed, usefully narrate the spatial relationship of the general-duty constructional delails different with these with the constructional delails of specific term, cut sheet feeder 10.More specifically, and consult Fig. 3, structure is placed on the top of transport platform 12,14 24 (hereinafter referred to as " sheet materials ") that cut sheet to take repeatedly, forms acute angle theta with the direction of arrow A DV with respect to the advance side of platform 12.Horizontal feed platform 12 aligns with transfer path FP and arrives inclination transport platform 14 IE lower end or input ends along transfer path guiding sheet material 24.
To transmit support platform 16 to align and be positioned under this end with the rising end 14RE of inclination transport platform 14.Though tilt table 14 is to transmitting the rigidity characteristics (i.e. taking in the layout repeatedly at it) that the height H of supporting platform 16 depends on the sheet material of banking up 24, preferable height H is by sheet material 24 " cantilever transmission profile " the determined height of ARC.In this scope of using, term " the transmission profile of cantilever " mean when sheet material 24 at one end (promptly by sheet material staggered/take layout repeatedly) be supported the lonely shape profile that produces when not being supported (promptly under action of gravity, produce vertical sagging) at the other end.Can utilize the vertical sagging vertical dimension H that roughly determines inclination transport platform 14 with respect to transmission support platform 16 of the transmission profile ARC of cantilever.
The revolving meber 28 that forms cylindrical surface 28C consequently transmits the periphery 28C that the plane surface 16S that supports platform 16 tangentially is aligned in revolving meber 28 near transmitting an end of supporting platform 16.In described embodiment, revolving meber 28 is the vacuum rotary drums with many apertures, and vacuum source 32 is configured to be communicated with vacuum rotary drum 28 fluids.More specifically, vacuum source 32 can be worked, and to produce pressure reduction, as following narration in more detail, its function is to attract the lead edge portion of sheet material 24 and the cylinderical surface 28C wipe contact of vacuum rotary drum 28.
Use separation member/holding element the device 17 that combines with revolving meber/vacuum rotary drum 28 moves or separates a sheet material from the sheet material of banking up 24 guaranteeing.More specifically, separation member/holding element 17 is arranged on the vacuum rotary drum 28 and is oriented to only promptly to be about 1/4th (0.25) inches relative small distance slightly in its rotation axis 28A downstream.Like this, the lower edge of separation member/holding element 17 be positioned at the periphery 28C of rotating cylinder 28 tangent horizon place or this horizon under.
At work, sheet material 24 is stacked on one or two of transport platform 12,14, and is sent to transmit and supports platform 16.When sheet material 24 arrived the rising end 14RE of tilt table 14, sheet material 24 forms or develops into the transmission profile ARC of cantilever and is sent to transmit supported platform 16.Sheet material 24 is at the less thickness of transmit supporting to form a rickle sheet material 24 on the platform 16 and having sheet material, simultaneously on sheet material be transferred the heeling condition support of platform 14.Vacuum rotary drum 28 cross the orlop 24L of material, promptly with sheet material generation pressure reduction that transmit to support that platform 16 contact, simultaneously, separate this sheet material 24L or make this sheet material become individual from the remainder of this heap.
Especially, take seriously idle running tube 28 separation member/holding element 17 bottom under when attracting single sheet of material 24L, the leading edge 24LE contact separation part/holding element 17 of the sheet material 24 of banking up.Descend most sheet material 24L from bank up sheet material 24 by " stripping " from move through separation member/holding element 17, the vertical walls 17W of 24 separated/holding element of all the other sheet materials of while 17 " maintains ".Separated/sheet material 24L of becoming individual tangentially crosses the cylinderical surface 28C of vacuum rotary drum 28, arrives for example input station (not shown) of the processing assembly of mail insertion system.
Consult Fig. 4,, can use air pressurization system 36, between all sheet materials of material sheet material 24 of banking up, to introduce the skim air for the ease of separating.More specifically, on each side that transmits support platform 16, a pair of energy chamber 40a, the 40b of sending can be set, pressurized air is introduced in the sheet material 24 of banking up along the limit.In described embodiment, pressure source 44 is arranged to be communicated with respectively sending energy chamber 40a, 40b fluid, supplying air to a plurality of side direction nozzles or aperture 46, these nozzles with air side to guiding the sheet material of banking up 24 into.
Therefore, the sheet feeder of shearing is included in and transmits the inclination transport platform 14 of supporting platform 16 upstreams, transmits profile with the sheet material that produces cantilever.When sheet material is sent to support platform 16, transmits profile and cause that sheet material is by " self supports ".The transmission profile of cantilever has reduced the weight that acts on the material 24 of banking up, and makes the friction minimum that is created between all single sheet of material.Like this, bevelled platform structure is convenient to by revolution vacuum rotary drum 28 separator sheet 24.On the contrary, the prior art sheet feeder use be basically parallel to transmit support platform and support the coplanar transport platform of platform with transmitting.Thereby, act on below sheet material, promptly be the function that is bearing in the concentrated weight of those sheet materials (because they can be to take repeatedly) on the area profile of sheet material with transmitting weight and the friction supported on the sheet material that platform contact.Will appreciate that in the friction of (and/or at sheet material and transmit to support between the platform) increase between all sheet materials by causing many sheet materials protection friction bondings, crossing vacuum rotary drum and move along with a sheet material when promptly taking seriously the revolution of idle running tube, make potentially to be divided into individual/lock out operation is complicated.
In addition, compressed-air actuated introducing, promptly introduce or be blown into the air of banking up at least one side of sheet material 24 and play supporting role, in the material of banking up, to separate and lubricated sheet material 24.Therefore, air lubrication reduces to act on the sheet material 24 or the friction between them, thus be convenient to by revolution vacuum rotary drum 28 separation/formation individual.
More than discuss mainly to concentrate on and transmit sheet materials 24 from inclination transport platform 14 and arrive to transmit and support platforms 16, be used for reliably separator sheet 24/ sheet material is divided into individual.But except reducing the friction between all sheet materials 24, an equal importance of sheet feeder 10 relates to and transmits all sheet materials reliably, promptly is included in the final or last sheet material among this heap.That is, because the reducing of sheet material/weight in heaps, final or last sheet material can experience not loading environment on the same group, so sheet feeder 10 must adapt to variable loading environment, sends sheet material to guarantee failure-free.
In Fig. 5 a, 5b, 6a and 6b, the present invention has used platen structure 50, carries out some functions, and some is unique for cut sheet feeder of the present invention.More specifically, platen structure 50 prevents owing to the repeatedly separation or the expansion of layout of taking of taking repeatedly the sheet material of banking up that the formed angle of this heap sheet material produces.Along with being transmitted this function along bevelled transport platform 14, the sheet material of banking up 24 becomes especially critical.And when material worked with formation cantilever transmission profile, platen 50 was used to adapt to the shape of banking up sheet material 24.And, along with sheet feeder 10 near the work operation at the end, promptly when last sheet material separated/when being divided into individual, sheet material weight reduces.
Though the additional function that transmission and weighted section formation are associated with balance and power normalisation, it will be convenient to relate to the discussion of each section by a differentiated characteristic.In described embodiment, transmission section 52 is the rectangular-shaped pieces on flat plane, and this other part is configured to contact with the belt conveyor 22 (seeing Fig. 6 a and 6b) of transport platform 12,14.Like this, produce frictional interface, it is sent to weighted section 54 by elastic webbing 56 with the translatory movement of belt conveyor 22.And, take repeatedly the tendency that heap slides backward or separates by stoping with rigidity in 56 the plane.In order to strengthen frictional interface, height can be rubbed that elastic body is adhered to or other method is fixed in the surface of the transmission section 52 of platen structure 50.
Can want the weighted section 54 of platen structure 50 to be divided into two or more part 60a, 60b and be spaced, be used to follow the purpose that cantilever transmits appearance profile.That is,, can wish weighted section 54 is distinguished, with the weight of more uniform distribution platen structure 50 on the sheet material of banking up 24 according to the size and the amount of curvature of sheet material.Will appreciate that increase or increasing, reduce perpendicular to the local load on the surface of platen 50 along with the face area that contacts with the sheet material 24 of banking up.In described embodiment, the extension by all elastic webbings 56 can connect file section 60a, 60b, but can use additional special use band or other flexible material, to keep flexibly connecting therebetween.
Flexibility is with 56 to be configured and to manufacture and have certain property behavior of structure: (i) be convenient to by belt conveyor 22 transmissions, prevent that (ii) each sheet material from promoting or becoming between a section of being accumulated in all platen section 52,54 and all belts 56, (iii) can make platen 50 follow the transmission appearance profile, and damage/fracture sheet material when (iv) preventing to make sheet material for individual.More specifically, flexibility planar is a rigidity with 56, remaining on the distance of separating between many sections or part 52,60a, the 60b, and the compressive load that adds that transmits transmission or " promotion " file section 60a, 60b necessity when carrying the sheet material of banking up 24 along with belt conveyor 22.And, be flexible outside the plane with 56, so that section 60a, a 60b be placed on the sheet material of banking up 24, and to transmit the curvature that profile produces irrelevant with cantilever.And, be with 56 can comprise low friction external surface, to prevent with 56 cuttings, wearing and tearing or the crinkled sheet material of banking up 24.More specifically, be with 56 can comprise metal construction core and low friction external surface.Can produce this outside face by bonding or other method multiple layer of fixing low friction heat plasticity or surface treatment.
In described embodiment, platen structure 50 comprises all inboard band 56a, the 56b that whole platen section 52,54 and part 60a, 60b are combined.But, leave the remainder of this heap or accumulate in all belt 56a, 56b and between all section 52,54 one section for preventing from the sheet material edge to rise, can wish in the outside and have belt 58a, the 58b of highly flexible for each side of all inner strap 56a, 56b.As Fig. 6 b clearly shown in, make these belts by pure elastomeric material, with guiding or keep the shape of this heap, especially when this heap sheet material when between bevelled and transmission support platform 14,16, transmitting.
In an embodiment of platen structure 50, use optical sensing devices, with existing of monitoring sheet material 24, promptly detect when supporting the separated or conveying of platform 16 from transmitting when last sheet material.This system (being clearly shown that in Fig. 6 b) generally includes a photounit with monitoring reflection luminous energy, reflection luminous energy maximum when photounit 70 is topped by sheet material, when sheet material 24 do not exist and no longer reflect luminous energy, be reflected light when not reaching photounit 70 reflection luminous energy less or less at least.In order to prevent that platen 50 is ineffective or optical sensing means to be lost efficacy, weighted section 52 can comprise not reflecting surface light transfer structure of a hole, transparency window or other.In described embodiment, the first file section 60a comprises an elliptical aperture 74, and align with photounit in this hole when making last sheet material become individual by the revolution vacuum rotary drum.
Though use optical sensor system determine the to bank up last sheet material of material 24 to be divided into individual, when being increased to cut sheet feeder 10, being continuous handling and also need to monitor when not interrupting with adding sheet material 24.Therefore, common way is to be combined with to be used to measure the system of thickness of banking up sheet material 24.This system monitors when indication transmit to support that platform 16 needs additional sheet material with a low thickness threshold value of continuous working when this heap thickness has arrived.Usually, a pivotal arm/wheel (not shown) contacts the driving surface of the sheet material 24 of banking up, and the rotary encoder (not shown) is measured the angle of pivotal arm/wheel simultaneously.When reaching a threshold angle, a signal drives belt conveyor 22, is used for that additional materials is fed to transmission and supports platform 16.
Be similar to the oblong hole 74 of the work that is used for the adaptive optics sensor-based system, one section of all stringer section 60a, the 60b of platen structure can have a gap or breach 78, to adapt to the work of thickness measurement system.In described embodiment, gap or breach 78 are formed on the shape that first file section 60a neutralization has general rectangular.Thereby the part of the surperficial 24F of the sheet material 24 of banking up is exposed, so that contact with pivotal arm/wheel.
In a word, platen structure 50 of the present invention has improved the reliability of cut sheet feeder 10, the forwarder that especially has the inclination transport platform.Platen structure 50 the taking of sheet material that prevent to bank up repeatedly arrange and separate or expansion, especially when these sheet materials when creep in bevelled transport platform or surface.And platen structure 50 adapts to the shape of banking up sheet material 24, even when material 24 produces cantilever transmission profile.And last sheet separation/platen structure 50 compensation sheet material weight reduces when becoming individual when making.At last, can adopt platen structure 50 to detect or thickness measurement system to adapt to the system, for example light that use many preexists.
