Media input 14 comprises an arrangement of components or structures configured to facilitate supplying media interaction device 10 with sheets of media. In the example embodiment illustrated, media input 14 is substantially similar to media outputs 34, 36 and 38. Media input 14 includes edge strip 44, tray 46 and tether 48. Edge strip 44 comprises a platform or ledge projecting from housing 12 proximate to media transport 16. Edge step 44 extends between tray 46 and housing 12 so as to space tray 46 from housing 12. Strip 44 enhances separation of tray 46 from housing 12 to reduce the likelihood of damage to housing 12. In other embodiments, edge strip and 44 may be omitted and tray 46 may be directly connected to housing 12.
Tray 46 comprises one of more structures forming a platform and providing a surface upon which sheets of media to be interacted upon may be placed, stored and loaded into media interaction device 10. Tray 46 is releasably connected to edge strip 44. Tray 46 is configured to separate or break-away from edge strip 44 in response to a load or force upon tray 46 exceeding a predetermined threshold value prior to substantial plastic deformation of tray 46 or of those portions connecting tray 46 to device 10. For purposes of this disclosure, the term “plastic deformation” means a deformation or bending of a structure such that the structure does not resiliently return to its original shape after the force that bent or deformed the structure has ceased. For purposes of this disclosure, with respect to the connection between a tray and a media interaction device or edge strip, a “substantial plastic deformation” is a plastic deformation to an extent such that the tray may no longer be reconnected to the media interaction device or such that even if the tray can be reconnected, the tray may no longer support similar loads of media without separation from the device as before such deformation.
The predetermined threshold value at which tray 46 separates from edge strip 44 and a remainder of media interaction device 10 is chosen such that tray 46 may support acceptable quantities of media to be interacted upon, such as a predetermined weight of a stack of the sheets, and such that tray 46 will separate or breakaway from edge strip 44 and a remainder of device 10 when the load upon tray 46 is so great that damage to tray 46 or damage to the connection between tray 46 and edge strip 44 may otherwise occur. In such a scenario, tray 46 is configured to separate from edge strip 44 (or housing 12 when edge strip 44 is omitted) to preserve tray 46 and the connecting structures. After breaking away, tray 46 may be reconnected to edge strip 44.
In the particular illustrated embodiment in which tray 46 is cantilevered, tray 46 is configured to break away or separate in response to the connection of tray 46 and edge strip 44 experiencing a torque exceeding a predetermined threshold torque. The torque experienced by tray 46 is a product of the downward force imposed upon tray 46 and the distance separating the center of gravity of sheets of media, which may impose at least some of the downward force upon tray 46, from the connection point. The threshold torque is the product of a predetermined threshold force and the distance separating an expected location of the center of gravity of sheets and the connection point. Since most sheets held by the tray will have the same center of gravity regardless of how large the stack of sheets is, separation of tray 46 is largely dependent upon the downward force imposed by the sheets. In certain circumstances, downward forces imposed upon tray 46 may have other sources such as other items shelved upon tray 46 or manual downward forces. In other embodiments in which tray 46 is not cantilevered, tray 46 may be configured to separate in response to experiencing a force exceeding a threshold independent of the location of applied force.
Although tray 46 is schematically illustrated as angled upward above horizontal, in other embodiments, tray 46 may be horizontal. Although tray 46 is schematically illustrated as a generally flat or planar plate, in other embodiments, tray 46 may have upwardly or downwardly extending sidewalls for containing or aligning such sheets of media upon tray 46. In yet other embodiments, tray 46 may alternatively comprise a non-cantilevered storage structure for media to be interacted upon. For example, tray 46 may alternatively comprise a media drawer, bin or the like. In such embodiments where tray 46 is not cantilevered, edge strip 44 may be omitted and tray 46 may alternatively be configured so as to not breakaway or separate from a remainder of media interaction device 10 in response to a load exceeding a threshold.
Tether 48 comprises a flexible member coupled between tray 46 and housing 12. For purposes of this disclosure, the term “coupled” shall mean the joining of two members directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two members or the two members and any additional intermediate members being integrally formed as a single unitary body with one another or with the two members or the two members and any additional intermediate member being attached to one another. Such joining may be permanent in nature or alternatively may be removable or releasable in nature.
Tether 48 suspends tray 46 after tray 46 has separated from media interaction device 10 in substantially all other respects. Tether 48 reduces an extent to which tray 46 falls and may serve to reduce potential damage to tray 46 after such separation. In other embodiments, tether 48 may be connected to edge strip 44 and an exterior of housing 12. In yet other embodiments, tether 48 may be omitted.
Media transport 16 comprises one or more structures or one or more mechanisms configured to engage and transport or move sheets of media from media input 14 relative to interaction element 18, selectively to one of finishing elements 22, 24, 26 and selectively to one of outputs 32, 34 and 36. In one embodiment, media transport 16 includes one or more rollers, belts and the like operably coupled to a motor (not shown) and driven by the motor so as to frictionally engage and move such sheets of media. In other embodiments media transport 16 may have other configurations.
Interaction element 18 comprises one or more devices configured to interact with sheets of media in one or more fashions. In one embodiment, interaction element 18 may comprise one or more inkjet printheads configured to eject ink or other fluid upon media in predetermined patterns or images. In one embodiment, media transport 16 may be configured to redirect printed upon sheets back to interaction element 18 for duplex printing. In another embodiment, interaction element 18 may comprise an electrophotographic printing device configured to apply toner to sheets of media on one or more sides. In yet another embodiment, interaction element 18 may be configured to scan or read data or images from sheets of media. In particular embodiments, interaction element 18 may be configured to perform multiple functions, such as scanning and printing. In some embodiments, interaction element 18 may be omitted, wherein media interaction device 10 interacts with media solely with either finishing elements 22, 24 and 26.
Finishing elements 22, 24 and 26 comprise elements configured to perform additional different interaction operations upon sheets of media. Examples of such additional interaction operations include stapling, folding, collating and the like. In particular embodiments, media transport 16 may be configured to move sheets of media to more than one of finishing elements 22, 24 and 26 before such sheets of media are discharged to one of outputs 32, 34 and 36. In yet other embodiments, media interaction device 10 may omit finishing elements 22, 24 and 26, wherein media outputs 32, 34 and 36 may be used to receive and separate different batches or sets of interacted upon media.
Media outputs 32, 34 and 36 and are configured to receive interacted upon media from device 10 and to present such sheets of media for withdrawal from device 10. Media outputs 32, 34 and 36 separate different batches are sets of media. In the exam illustrated, media outputs 32, 34 and 36 are vertically arranged and cantilevered along an exterior of housing 12. Although the interaction device 10 is illustrated as including three in media outputs, and other environments, media interaction device 10 may include greater or fewer than three media outputs and such media outputs and other arrangements along an exterior of housing 12.
Media outputs 32, 34 and 36 are each substantially identical to one another. Each of media output 32, 34, 36 includes edge strip of 54, tray 56 and tether 58. Edge strip 54 comprises a platform or ledge projecting from housing 12 proximate to media transport 16. Edge strip 54 extends between tray 56 and housing 12 so as to space tray 56 from housing 12. Edge strip 54 enhances separation of tray 56 from housing 12 to reduce likelihood of damage to housing 12. In other embodiments, edge strip 54 may be omitted and tray 56 may be directly connected to housing 12.
Tray 56 comprises one of more structures forming a platform and providing a surface upon which sheets of discharged media may be placed and stored. Tray 56 is releasably connected to edge strip 54. Tray 56 is configured to separate or break-away from edge strip 54 in response to a load or force upon tray 56 exceeding a predetermined threshold value. The predetermined threshold value at which tray 56 separates from edge strip 54 and a remainder of media interaction device 10 is chosen such that tray 56 may support acceptable quantities of discharged media, such as a predetermined weight of a stack of sheets and such that tray 56 will separate or breakaway from edge strip 54 when the load upon tray 56 is so great that damage to tray 56 or damage to the connection between tray 56 and edge strip 54 may otherwise occur. In such a scenario, tray 56 is configured to separate from edge strip 54 (or housing 12 when edge strip 54 is omitted) to preserve tray 56 and the connecting structures. After breaking away, tray 56 may be reconnected to edge strip 54.
Although tray 56 is schematically illustrated as angled upward above horizontal, in other embodiments, tray 56 may be horizontal. Although tray 56 is schematically illustrated as a generally flat or planar plate, in other embodiments, tray 56 may have upwardly or downwardly extending sidewalls for containing or aligning such sheets of media upon tray 56.
Tether 58 comprises a flexible member coupled between tray 56 and housing 12. For purposes of this disclosure, the term “coupled” shall mean the joining of two members directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two members or the two members and any additional intermediate members being integrally formed as a single unitary body with one another or with the two members or the two members and any additional intermediate member being attached to one another. Such joining may be permanent in nature or alternatively may be removable or releasable in nature.
Tether 58 suspends tray 56 after tray 56 has separated from media interaction device 10 in substantially all other respects. Tether 58 reduces an extent to which tray 56 falls and may serve to reduce potential damage to tray 56 after such separation. In other embodiments, tether 58 may be connected to edge strip 54 in lieu of housing 12. In yet other embodiments, tether 58 may be omitted.
As further shown by
In the example illustrated, trays 56 are configured to separate from edge strips 54 by pivoting downward under the force of gravity and a load upon such trays as indicated by arrows 70. Upon separation, tethers 58 limit the degree to which trays 56 fall to reduce damage to trays 56. In other embodiments, trays 56 may be permitted to fall in the absence of tethers 58. Although not illustrated, in those embodiments in which media input 14 is similar to media outputs 32, 34 and 36, media input 14 may also separate or breakaway in response to experiencing a load greater than a predetermined threshold.
Job separator assembly 130 comprises an arrangement of components or structures coupled to housing 112 and configured to receive and separate discharged media. In the example illustrated, job separator assembly 130 is removably coupled to housing 112.

Brackets 200 generally include multiple horizontally aligned mounting portions 214 for each media output 132-138. Each mounting portion 214 includes a mounting cavity 216, tongue 218 and tether portion 219. Mounting cavity 216 comprises an opening extending into the beam structure of bracket 200. Mounting cavity 216 includes upper portion 220, middle portion 222 and lower portion 224. Upper portion 220, federal portion to 22 and lower portion to 24 are each configured to bear against similarly shaped portions of tray 206 when tray 206 is connected to bracket 200. Upper portion 220 facilitates connection of tray 206 to bracket 200 and is generally a downwardly facing angled surface. Upper portion 220 extends at an angle above horizontal to facilitate downward linear insertion of tray 206 into cavity 216. Middle portion 222 extends between upper portion 220 and lower portion 224. In the particular example illustrated, tether 208 extends from middle portion 222. Lower portion 224 facilitates separation of tray 206 from bracket 200 and is generally an upwardly facing arcuate or curved surface. Lower portion 224 facilitates rotation of tray 206 about a substantially horizontal axis in response to a downward force or load upon tray 206. In other embodiments, mounting cavity 216 may have other configurations.
Tongue 218 assists in retaining tray 206 to bracket 200 in the absence of a load upon tray 206 exceeding the threshold. Tongue 218 is shown in more detail in
Tether portion 219 comprises that portion of bracket 200 from which tether 208 extends. In the particular example embodiments illustrated, tether portion 219 comprises a recess configured to receive projections of tether 208 such a tether 208 is snapped to bracket 200. As a result, tether 208 may be separately fabricated and more easily assembled to bracket 200 without tools. In other embodiments, tether portion 219 of bracket 200 may alternatively be configured to facilitate securement of tether 208 to bracket 200 by fasteners, adhesives or welding.

In the particular example embodiment illustrated, edge strip 204 is releasably connected to housing 112 (shown in
Tray 206 comprises one of more structures forming a platform and providing a surface upon which discharged sheets of media t are stored and are separated. Each tray 206 is releasably connected to a mounting portion 214 of bracket 200. Each tray 206 is configured to separate or break-away from brackets 200 in response to a load or force upon tray 206 exceeding a predetermined threshold value. The predetermined threshold value at which tray 206 separates from brackets 200 and a remainder of media interaction device 10 is chosen such that tray 206 may support acceptable quantities of media to be interacted upon, such as a predetermined weight of a stack of the sheets and such that tray 206 will separate or breakaway from brackets 200 when the load upon tray 206 is so great that damage to tray 206 or damage to the connection between tray 206 and brackets 200 may otherwise occur. In is such a scenario, tray 206 is configured to separate from brackets 200 to preserve tray 206 and the connecting structures.
In the particular illustrated embodiment in which tray 206 is cantilevered, tray 206 is configured to break away or separate in response to the connection of tray 206 to bracket 200 experiencing a torque exceeding a predetermined threshold torque. The torque experienced by tray 206 is a product of the downward force imposed upon tray 206 and the distance separating the center of gravity of sheets of media, which may impose at least some of the downward force upon tray 206, from the connection point. The threshold torque is the product of a predetermined threshold force and the distance separating an expected location of the center of gravity of sheets and the connection point. Since most sheets held by the tray will have the same center of gravity regardless of how large the stack of sheets is, separation of tray 206 is largely dependent upon the downward force imposed by the sheets. In certain circumstances, downward forces imposed upon tray 206 may have other sources such as other items shelved upon tray 206 or manual downward forces. In other embodiments in which tray 206 is not cantilevered, tray 206 may be configured to separate in response to experiencing a force exceeding a threshold independent of the location of applied force.
In one embodiment, the predetermined threshold value is between about 9 pounds and about 48 pounds and nominally between about 12 pounds and 37 pounds spaced from the connection between bracket 200 and tray 206 by about 210 mm. In other embodiments, the predetermined threshold may have other values depending upon the materials and configuration of tray 206, the structures connecting tray 206 to edge strip 204 or to housing 112 and the anticipated dimensions of media that will be supported by tray 206. After breaking away, tray 206 may be reconnected to brackets 200.
Although tray 206 is illustrated as angled upward above horizontal, in other embodiments, tray 206 may be horizontal. Although tray 206 is illustrated as a generally flat or planar plate, in other embodiments, tray 206 may have upwardly or downwardly extending sidewalls for strengthening tray 206 or for containing or aligning such sheets of media upon tray 206.
Mounting portions 254 extend on opposite sides of platform 250 and are configured to releasably mount to mounting portions 214 of brackets 200. Each mounting portion 254 generally includes mounting projection 256, groove 258 and tether portion 259. Mounting projection 256 comprises a structure configured to be received within mounting cavity 216 of bracket 200. In the example illustrated, mounting projection 256 is configured to mate with corresponding opposite surfaces of mounting cavity 216 when tray 206 is connected to bracket 200. Mounting projection 256 includes upper portion 260, middle portion 262 and lower portion 264. Upper portion 260 comprises upwardly facing angled surface configured to abut upper portion 220 of mounting cavity 216 (shown in
Groove 258 comprises an elongate channel configured to slidably receive tongue 218 (shown in
Beams 270 serve as clips to clamp about tongue 218 to assist in retaining tray 206 to brackets 200. At the same time, beams 270 are configured to spread apart and flex in response to a predetermined threshold load upon tray 206, permitting tongue 218 to be withdrawn from between beams 270. Beams 270 cooperate with one another to form head receiving portion 274, captured portions 276 and indents 278. Head receiving portion 274 is an elongate channel configured to slidably receive head portion 232 of tongue 218. Captured portions 276 comprise elongate bars configured to slide along and within grooves 236 of tongue 218. Captured portions 276 bear against head portion 232 to retain tray 206 to bracket 200. Captured portions 276 spread apart to permit head portion 232 to pass therebetween during separation of tray 206. Indents 278 comprise detents configured to receive protrusions 234 of tongue 218 (shown in
Tether portion 259 comprises that portion of mounting projection 256 from which tether 208 extends. Tether portion 259 includes cavity 284 and recess 286. Cavity 284 comprises an opening above recess 286 configured to receive and store a length of tether 208 while mounting projection 256 is received within mounting cavity 216 and while tray 206 is mounted to bracket 200. Recess 286 comprises an opening having a reduced mouth configured to receive a portion of tether 208 to facilitate snapping of tether 208 to mounting projection 256. In other embodiments, recess 286 may be omitted where tether 208 is secured to tray 206 in other fashions such as with fasteners, adhesives or welds or where tether 208 is integrally formed as part of a single unitary body with mounting projection 256 of tray 206. In still other embodiments, mounting projection 256 may omit tether portion 259 where tether 208 extends from another portion of tray 206.

According to one example embodiment, each beam 270 has a length of about 23 mm and a height of about 8 mm. Mounting projection 256 has a width of about 24 mm. Tray 206 At least mounting projections 256 of tray 206 are integrally formed as a single unitary body out of a polymeric material such as Cycoloy C1110HF commercially available from GE Plastics. In a particular example illustrated, such material has a tensile modulus of 2.482 GPa and a flexural strength of 86.9 MPa. In the example embodiment, beams 270 are configured to deflect or flex approximately 1 mm during release of tongue 218. In other embodiments, tray 206 and bracket 200 may have other dimensions and may be formed from other materials.
Although bracket 200 is illustrated as including mounting cavity 216 while tray 206 includes mounting projection 256, in other embodiments, this relationship may be reversed. Although bracket 200 is illustrated as including tongue 218 while tray is illustrated as including groove 258, in other embodiments, this relationship may also be reversed. Although bracket 200 is illustrated as including four mounting portions 214, in other embodiments, bracket 200 may alternatively include greater or less than four mounting portions 214.
