Referring now specifically to
FIGS. 1 and 2 , asheet processing apparatus 100 is presented according to one aspect of the invention.FIG. 1 presents a schematic side view of theapparatus 100, andFIG. 2 presents a partial cross-sectional view taken along line 2-2 ofFIG. 1 .Apparatus 100 comprises asheet handling device 102 for flipping asheet 104. Thesheet 104 has anend 106. Thesheet handling device 102 comprises arotary sheet flipper 108 that comprises asheet holder 110 that receives thesheet end 106 and flips thesheet end 106 with thesheet 104 otherwise unrestrained. A blowingsource 112 is oriented to assist flipping thesheet 104. - The
apparatus 100 ofFIG. 1 is a stacker, for purposes of illustration, but the invention is not limited to use in a stacker. If configured as stacker, theapparatus 100 places thesheet 104 on a stack ofsheets 105. Theapparatus 100 comprises asheet transport path 114 that implements driven nips (not shown), for example, to move thesheet 104 along thetransport path 114, as indicated byarrow 116. An example of a driven nip is a pair of opposing rollers, one of the rollers being driven. Such mechanisms are very well known in the sheet transport art. -
Apparatus 100 also comprises a diverter 118 that alternatively directs thesheet 104 totransport path 120, ortransport path 122, depending upon the position of the diverter 118. InFIG. 1 , the diverter is positioned to direct thesheet 104 to thetransport path 122.Transport path 122 is directed to therotary sheet flipper 108, andtransport path 120 is directed to exit the right side of the apparatus, for further sheet processing by another apparatus for example. Thesheet 104 may be directed to thetransport path 120 by rotating the diverter 118 counter-clockwise around a pivot 124. The transport path may be provided with drivennips -
FIG. 3 presents a partial cross-sectional view of theapparatus 100 taken along line 3-3 ofFIG. 1 . Anair source 130 is in fluid communication with the blowingsource 112 via a hose ortube 132. Theair source 130 may be any device suitable for developing air movement, for example a blower, fan, or a compressed air source (a compressor). One, two, or more blowingsources 112 may be provided, and more than onehose 132 may be provided to supply multiple blowing sources. A wye-connection 134 may be provided to split the output from theair source 130 between two blowingsources 112. Other plumbing arrangements may also be implemented, such as one or more manifolds. Aregulator 136 may be provided to adjust the flow and/or pressure applied to the blowingsource 112, for example a bleed valve that vents some of the flow to ambient. Theregulator 136 may be adjustable to permit tuning the blowingsource 112 for sheets having particular properties. Alternatively, the air source motor may be regulated to provide a desired flow, for example by regulating DC voltage supply to a DC air source motor. Theair source 130 and/orregulator 136 may be mounted anywhere on theapparatus 100 where convenient, particularly where access is available to adjust theregulator 136. Theair source 130 is shown mounted on a side panel of theapparatus 100. A more convenient location may be on the back of the apparatus. Theair source 130 maybe mounted immediately adjacent the blowingsource 112, in the area of therotary sheet flipper 108 for example, thereby eliminating most or all of the interconnecting hose. - Referring again to
FIGS. 1 and 2 , thesheet holder 110 is configured as a wheel mounted on a shaft 138, the wheel comprising atongue 140 that defines aslot 142 that receives thesheet end 106. The exemplaryrotary sheet flipper 108 presented in the drawings comprises twosheet holders 110 each configured as a wheel and each having twotongues 140 diametrically opposed on each wheel. -
FIG. 4 presents a partial cross-sectional view of theapparatus 100 taken along line 4-4 ofFIG. 2 . Referring now toFIGS. 2 and 4 , thesheet handling device 102 comprises atamper 144 that traps thesheet end 106 after flipping, and aside plate 214. Thesheet holder 110 comprises acam 146. Thetamper 144 comprises atamper shaft 148, atamper arm 150 mounted to thetamper shaft 148 that engages thesheet end 106, and acam arm 152 mounted to thetamper shaft 148 that interacts with thecam 146. - According to a further aspect of the invention, a sheet flipping method is provided comprising receiving the
sheet end 106, flipping thesheet end 106 with thesheet 104 otherwise unrestrained, and blowing thesheet 104 to assist flipping thesheet 104. The method may comprise placing thesheet 104 on a stack ofsheets 105. The blowing may also be oriented and re-oriented in order to adjust thesheet handling device 102 for processing ofsheets 104 having different characteristics. Thesheet end 106 may be trapped after flipping. The method may comprise placing thesheet 104 on a stack ofsheets 105 and trapping thesheet end 106 on the stack ofsheets 105 after flipping. -
FIGS. 5-8 present the same partial cross-section asFIG. 4 , but at different stages of operation of thesheet handling device 102 so certain components are in different positions depending upon the stage of the sequence. Operation of thesheet handling device 102 will now be discussed in more detail with reference toFIGS. 4-8 . Blowing, as indicated byarrows 154 may be initiated by powering theair source 130 at the same time the main drive for the apparatus is powered. Referring now specifically toFIG. 4 , thesheet 104 is driven by thenip 128 as indicated byarrow 156 so that thesheet 104, and more specifically thesheet end 106 is received by thesheet holder 110 within the slot (142 ofFIG. 1 ) defined by thetongue 140. Referring now toFIG. 5 , a counter-clockwise rotation of thesheet holder 110 is initiated by a motor as thenip 128 continues to drive thesheet 104. One of thecams 146 interacts with thecam arm 152, which causes thetamper 144 to rotate clockwise and lift thetamper arm 150 from the stack ofsheets 105. At this point of the rotation of thesheet holder 110, thesheet 104 is approximately aligned with the right edge of thestack 105, and thesheet end 106 is positioned beneath thetamper arm 150. Rotation of thesheet holder 110 continues until thecam 146 passes the end of thecam arm 152 thus releasing thetamper 144 to rotate counter-clockwise under a spring load, or other force such as a solenoid or the force of gravity for example, until thetamper arm 150 rests on thesheet end 106 so that thesheet end 106 is gripped between thetamper arm 150 and thesheet stack 105, as is shown inFIG. 6 . Thetamper 144 may be damped by a damper, particularly if thetamper arm 150 tends to bounce. A quick gripping of thesheet end 106 after thesheet holder 110 releases it is desirable so that the blowingsource 112 does not have an opportunity to blow theentire sheet 104 away. Gripping in the range of 15-60 milliseconds from the time the leading edge of thesheet 104 first strikes the side plate 214 (FIG. 6 ) is believed to be satisfactory. All or part of thetongue 140, for example about one-third of it, may be disposed between thesheet end 106 and the stack ofsheets 105 when the tamper first contacts thesheet end 106 and traps it. Rotation of thesheet holder 110 continues until thetongue 140 is removed, and then stops. Referring now toFIG. 7 , thenip 128 continues to drive thesheet 104, which forms a loop moving to the left as indicated byarrow 158. Eventually the end of thesheet 104 opposite thesheet end 106 exits thenip 128 and thetransport 122, as shown inFIG. 8 . The blowing provided by the blowingsource 112 urges continuing movement of the balance of the sheet, as indicated byarrow 156, so that ultimately the sheet lies flat on thestack 105. Thesheet holder 110 maybe rotated into the position shown inFIG. 4 , at an appropriate time, in order to repeat the cycle for another sheet. - Without the blowing provided by the blowing
source 112, sheets having certain properties, particularly sheets having a low beam strength, tend to remain in the looped position on the top of thestack 105. Stated differently, the motion indicated inFIG. 8 does not occur the sheet remains looped and does not open. The next sheet is deposited and several sheets may be deposited in this condition. The looped sheet is damaged and the stack is altered in an undesirable manner that may render the stacker inoperable until the looped sheet (or sheets) is cleared. - Referring again to
FIG. 1 , thesheet stack 105 rests on atray 160. The tray may be removable, and may be provided with wheels (not shown) to facilitate transporting it from one location to another on a shop floor. The elevation of the tray is controlled by multiple chain drives 162, or other suitable mechanism for controlling the elevation of a tray in a stacker. In one embodiment, fourchain drives 162 are provided, one at each corner of thetray 160. Eachchain drive 162 comprises asprocket 164 and achain 166. The chain drives are controlled so that thetray 160 lowers as sheets are added to thesheet stack 105 such that the top of thesheet stack 105 remains at an approximately constant location. - Referring now to
FIGS. 9 and 10 , a schematic end view and a schematic front view, respectively, of the blowingsource 112 and mount 113 are presented.Mount 113 comprises abracket 168. Aclamp 170 holds atube 172 in place and is mounted to thebracket 168 by afastener 174. Anotherfastener 176 mounts thebracket 168 in place within theapparatus 100, as shown inFIGS. 2 and 4 -8. The tube. 172 is connected to thehose 132 ofFIGS. 1 and 3 . Referring again toFIGS. 9 and 10 , and according to one aspect of the invention, the blowingsource 112 may be oriented by moving it in afirst direction 178, asecond direction 180, and/or at least a third direction 182 (anadditional direction 184 is also indicated). The blowingsource 112 may also be oriented by rotating it, for example, aboutfastener axis 186 orfastener axis 188. The blowing source may be oriented by translating it and rotating it. Themount 113 may be made adjustable to permit orienting and re-orientating the blowingsource 112. - Referring now to
FIGS. 11 and 12 , a schematic side view and a schematic front view, respectively, of ablowing source 190 and mount 192 are presented according to another embodiment of the invention.Mount 192. comprises abracket 198. The blowingsource 190 comprises atube 194 perforated with an array ofholes 196. Thetube 172 is connected to the hose ofFIGS. 1 and 3 . Referring again toFIGS. 11 and 12 , aclamp 200 holds thetube 194 in place and is mounted to thebracket 198 by thefastener 174. Thefastener 176 mounts thebracket 168 in place within theapparatus 100. The blowingsource 190 and mount 192 ofFIGS. 11 and 12 may be a direct substitute for the blowingsource 112 and mount 113 ofFIGS. 9 and 10 . A mirror image arrangement may be substituted on the other side of the rotary sheet flipper 108 (on the left inFIG. 2 ). As shown inFIG. 2 , therotary sheet flipper 108 is rotatable about an axis ofrotation 202. Referring again toFIGS. 11 and 12 , thetube 194 has alongitudinal axis 204, and may be parallel to the axis ofrotation 202 of therotary sheet flipper 108. - The blowing
source 190 may be oriented and re-oriented as previously described with reference to blowingsource 112. Further additional directions ofadjustment source 190 may be rotated about thelongitudinal axis 204, as indicated byarrows 210. The array ofholes 196 may be deflected toward the stack ofsheets 105, as shown inFIG. 11 . - The
holes 196 may be aligned in one or more lines. Two rows ofholes 196, for example, may be implemented. One or more rows ofholes 196 may be deflected toward the stack ofsheets 105, or just one row out of multiple rows ofholes 196 may be deflected toward the stack orsheets 105. Theholes 196 need not be aligned in lines since any pattern that achieves the result described herein may be implemented in the practice of the invention. - In a certain embodiment, the
tube 194 is copper with an outside diameter of 0.60 inches and an inside diameter of 0.57 inches (standard ½″ copper pipe). There are four (4) holes 196, eachhole 196 having a diameter of 0.11 inch, twoholes 196 on either side of themount 192, aligned in a straight line and deflected toward the stack ofsheets 105, as shown inFIG. 11 . Two such mirror arrangements were provided, one on either side of arotary sheet flipper 108, powered by an Ametek® blower part number 119350-00 that generates the curve shown inFIG. 13 (according to manufacturer's specifications), available from Ametek, Kent, Ohio, U.S.A. Anadjustable bleed regulator 136 was provided and operated from full close (no bleed) to full open (full bleed) depending upon the tuning desired. - Referring now to
FIG. 14 , a top view of one embodiment of thetamper 144, side plate 214 (FIG. 6 ), and stack 105, with portions broken away is presented. Thetamper 144 may comprise two L-shapedtamper arms 150 disposed on either side of a center T-shapedtamper arm 151. Thetamper arms tamper shaft 148 ofFIGS. 2 and 3 -8. - Referring again to
FIG. 1 , acontroller 212 is provided to control operation of theapparatus 100. Thecontroller 212 may implement software, hardware, and/or firmware. The controller may be configured according to methods and practices known in the art. - In view of the wide variety of embodiments to which the principles of the present invention can be applied, it should be understood that the illustrated embodiments are exemplary only, and should not be taken as limiting the scope of the present invention.
