Abstract
Description
- This invention is directed to a stacker for stacking envelopes received from a machine that has placed images on the envelopes, and more particularly, to an envelope stacking apparatus that stacks enveiopes on long edges thereof.
- An efficient and cost effective way to neatly stack a high capacity (more than 40 or 50) of envelopes exiting an imaging apparatus has not been found. Conventional envelope stackers have shown to be deficient in accomplishing this task. For example, when envelopes are stacked in a simple catcher box as shown in FIG. 1, they tend to fall sideways. This is because the envelope flap is slightly open and also forms three paper thicknesses on the same side which creates an unstable medium to stack. Also, individual envelopes alone are much more variable from style to style than paper, i.e., some stack better or worse than others. In addition, prior art stackers do not address the problem of the desirability of stacking envelopes 1 - N which would make the envelope match documents printed and stacked 1 - N. Simple catch boxes, as for example, in FIG. 1, which most low capacity stackers employ, are N - 1 stackers, so that the user must perform a very tedious manual inversion of the envelopes in order to make the envelope printing order match the letter order that must be inserted into the envelopes. Therefore, if possible, the imaged or addressed side of envelopes should be stored 1 to N as shown in FIG. 2.
- An object of the present invention is to provide a simple and cost effective envelope stacker.
- Therefore, the present invention provides an envelope stacker according to
claim 1 of the appended claims. - The invention further provides an evelope stacker according to claim 5 of the appended claims
- The invention further provides a printer according to
claim 8 of the appended claims. - Embodiments of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:
- FIG. 1 is a partial side view of a prior art envelope stacker;
- FIG. 2 is an exploded schematic showing envelopes stacked in 1 - N order;
- FIG. 3 is a schematic front view of the high capacity envelope stacker apparatus of the present invention attached to a conventional copier/printer;
- FIG. 4 is a partial, schematic isometric view of the high capacity envelope stacker apparatus of FIG. 3 showing the envelope flipping member actuated;
- FIG. 5 is a partial, schematic, isometric view of the high capacity envelope stacker apparatus of FIG. 3 with envelopes that have been flipped onto one of their long edges;
- FIG. 6 is a partial, schematic side view of an alternative embodiment of the high capacity envelope stacker apparatus of the present invention; and
- FIG. 7 is a partial, schematic side view of another alternative embodiment of the high capacity envelope stacker apparatus of the present invention showing a captive pin for rotating the flipper plate.
- Referring now to the drawings in detail, and wherein like numbers indicate like elements, high capacity
envelope stacker apparatus 100 is shown attached to an envelope feeding copier/printer, such as shown in allowed US-A-5,139,250 by John D. Zoltner and entitled OSCILLATING BLADE ENVELOPE ROTATOR, which is incorporated herein by reference to the extent necessary to practice the present invention. - The high capacity
envelope stacker apparatus 100 of the present invention is used only part of the time an imaging apparatus, such as, a printer is in use. As such, it must be compact and unobtrusive from an appearance standpoint, and since it is not a dedicated part of the imaging apparatus, it must be inexpensive. - Such an envelope stacker is shown in FIG. 3 as 100 connected to an
exemplary printer 30, such as the Xerox 4045®, that includes anenvelope feeder 10.Envelope feeder 10 is a high capacity (200 envelopes), gravity-fed, load-while-run (when a cover safety interlock is not used) apparatus which is adapted to be connected to a printer with a long dimension of theenvelopes 8 placed against the end and short edge dimension of the printer for minimum footprint usage. The envelopes are inserted flap down within walls ofbin 13. A planar bottom and envelope supporting portion of the bin has a relieved portion therein in the shape of an envelope flap that permits the flap of the lowermost envelope to extend thereinto. A motor and brackets support a picker blade by way of a shaft (not shown) for back and forth or oscillatory movement within a predetermined space along the bottom surface ofbin 13. On demand, the blade (not shown) is rotated by the motor from a first or homeposition underlying bin 13 to a second position withinprinter 30. The picker blade sweeps each envelope sideways and pivots them from a short edge dimension to a long edge dimension within the printer betweenguides scuffer wheel 55 and fed out of the printer byfeed rolls 60 into high capacityenvelope stacking apparatus 100. - High
capacity envelope stacker 100 of the present invention in FIGS. 3 - 5 accepts envelopes from copier/printer 30 at about a 30° angle and comprises a catch tray havingside walls end walls envelope receiving compartment 120 and anenvelope storage compartment 110. The two compartments are separated by aslidable partition 113 andcompartment 120 has abottom shelf 121. Brush-like snubbers 118 are positioned on opposite sides ofwalls flipper plate 122 is positioned withincompartment 120 and mounted byhinge 123 to be rotated through an arc of 90° from a position on top of bottom receivingshelf 121past snubbers 118 by anactuator disc 125 driven by a motor (not shown).Actuator disc 125 is connected to pivotingflipper plate 122 by an eccentrically mountedlink 126. - In operation, envelopes exit the output or right end of copier/
printer 30 as viewed in FIG. 3, at an angle of approximately 30° in the direction of arrow A of FIG. 4 and are received in receivingcompartment 120 and coming to rest onflipper 122. Envelopes pass aphotosensor 40 in the exit path of copier/printer 30 which includes anemitter 41 and a detector orreceiver 42. The software of copier/printer 30 is designed such that a signal fromsensor 40 that an envelope has passed that station is sent to the onboard computer of the copier/printer. After a predetermined delay, to allow the envelope to come to rest in the stacker onflipper plate 122, a signal is sent from the computer to actuate the motor that turnsactuator disc 125 one revolution. This acts onlink 126 whichpivots flipper plate 122 90°. Flipperplate 122 in turn rotates the envelope thereon 90°past brush snubbers 118 until the envelope is captured between the brush snubbers andslidable partition 113. As this operation is repeated for each individual envelope,slidable partition 113 moves in the direction of arrows B to the left of FIGS. 4 and 5 in small incremental steps so that a force to sufficiently orient the envelopes vertically (on a long edge dimension thereof) is always maintained. After a run is completed, the operator pushes the partition further to the left, grasps the stack of envelopes with one hand extending through relieved or cut-outarea 105 and the other at the exposed end of the envelopesadjacent brush snubbers 118 and pulls them from the storage compartment for deposit in another area.Slidable partition 113 is then manually returned to the extreme right end of the storage compartmentadjacent brush snubbers 118. It should be understood that a spring could be used to automatically return the slidable partition to this home position, if desired. - The resultant stacked envelopes from this operation are stacked (image side) 1 - N which is the desired sequence since copy sheets that are to be inserted into the envelopes are usually stacked 1 - N. The advantages of this stacker apparatus over prior envelope stackers include the 1 - N order integrity; low-complexity; low unit manufacturing cost; user friendliness and safe operation.
- An alternative embodiment of the high capacity envelope stacker in accordance with the present invention is shown in FIGS. 6 and 7 in which like numbers represent like elements of FIGS. 3 - 5. In FIG. 6,
envelopes 8 enterstacker 150 and rest flap side down on top offlipper plate 122 which is parallel tobottom shelf 153. Whenmotor pulley 160 is actuated by a signal from the stacker logic circuit (not shown),disc 155 is rotated bybelt 161 in the direction of arrow D for one revolution for each envelope andpin 156 that is attached todisc 155lifts flipper plate 122 which is spring loaded down andenvelope 8past brushes 118 onto a long edge thereof and againststopper plate 170. As the process continues for each incoming envelope, the action offlipper plate 122 pushes the envelopes andmovable support 154 along rails ortubular slides 111 in the direction of arrows B towardend member 152 and away fromend member 151. The stacker apparatus of FIG. 7 is the same as that shown in FIG. 6 except thatpin 156 is shown captured within abracket 130 connected to the underside offlipper plate 122. As a result, rotation ofdisc 155 causespin 156 to ride withinbracket 130 to thereby raise and lowerflipper plate 122 in order to stack incoming envelopes.
