Technical field
[0001] This invention relates to an apparatus which is used for pocketing documents.
Background art
[0002] In a typical data processing application such as the sorting of docments like checks
or punched cards, for example, the series of pockets into which the documents are
sorted are generally aligned in a horizontal direction. For some applications, the
series of pockets is aligned in a vertical direction; this is true when space considerations
are very important.
[0003] One of the situations which is encountered with a pocketing apparatus having vertical-aligned
pockets is that there generally is a change of direction required in transporting
the documents. In this regard, the documents are moved in one direction (generally
horizontally) to a transfer station, and thereafter, they are moved in a second direction
(generally downwardly) to a plurality of vertically-aligned pocket members where they
are selectively sorted into individual pockets.
[0004] One of the problems encountered with a pocketing apparatus of the type described
in the previous paragraph is that documents tend to jam at the transfer station where
the change of direction is effected, making extraction of the jammed document difficult.
[0005] This problem is alleviated in the arrangement disclosed in GB-A-1193515 and DE-A-1611368
both of which documents disclose apparatus having all of the features set out in the
pre-characterizing part of claim 1. These patents describe sheet sorting apparatus
of a modular design in which multiple units each having vertically-aligned pockets
may be assembled side-by-side to increase the pocketing capability of the system.
The sheets to be pocketed are transported in a horizontal direction through each unit,
entering the unit through an entry port and leaving the unit through an exit port.
A selector adjacent to the exit port is arranged to divert a selected sheet to be
transported in a vertical direction and is then directed into one of the pockets by
the action of one of a plurality of selectors positioned opposite the mouth of the
pocket. To facilitate the removal of sheets which become jammed in the vertical sheet
travel path, a unit may be moved out of cooperative relation with the adjacent unit
to allow access to the jammed sheet.
[0006] A similar sheet sorting apparatus is described in US-A-3649009. The sorting apparatus
comprises one or more modules having a plurality of vertically-aligned pockets for
storing sheets and deflector members associated with each of the pockets to route,
when actuated, the sheet from the transport mechanism into a corresponding pocket.
The transport mechanism is mounted in such a way as to enable camming the transport
mechanism away from the pockets to facilitate the removal of a jam occurring in the
movement of the sheet along the vertical sheet path.
[0007] A disadvantage of the aforementioned arrangements is that the individual units must
be moved away from one another to remove a sheet which has become jammed during its
transportation along its vertical path which, in cases where the apparatus contains
a large number of modules, is rather cumbersome.
Disclosure of the invention
[0008] The document pocketing apparatus of this invention obviates the problem mentioned
above.
[0009] Thus, according to the invention, there is provided a document pocketing apparatus
including a plurality of pocket members for selectively receiving documents to be
pocketed; an entry port to said apparatus and an exit port from said apparatus; first
transport means for moving documents from said entry port to said exit port in a first
direction; and a selector located between said entry and exit ports for selectively
diverting a document to be pocketed so as then to be moved by a second transport means
in a second direction substantially perpendicular to said first direction, characterized
by a transfer station including first and second opposed track members for receiving
therebetween a document transported thereto by said second transport means; and a
third transport means for moving said document in a third direction substantially
perpendicular to said first and second directions from said transfer station to said
plurality of pocket members, said first track member being mounted on a frame arranged
for movement along said second direction between first and second positions relative
to said apparatus, so as to facilitate removal of a document which may become jammed
at said transfer station.

Best mode for carrying out the invention
[0011] Fig. 1 is a general, perspective view of a data processing system 10 in which a preferred
embodiment of the apparatus 12 for pocketing documents, made according to this invention,
may be used.
[0012] The system 10 (Fig. 1) portrayed includes an encoder, although, naturally, the apparatus
12 may be used with other data processing equipment in which pocketing or sorting
of documents is required. Basically, an encoder is an apparatus which prints or encodes
the courtesy amount (monetary amount) of documents like checks in MICR ink on the
front of the associated documents. Additionally, the system 10 performs certain bank-stamping
functions on the backs of the documents. The system 10 includes a keyboard (KB) 14,
a display 16 and the various, known, encoder components such as a MICR printer, etc.,
18 for performing the various functions described.
[0013] The system 10 also includes a control unit 20 which is shown schematically in Fig.
2. The relationship of the control unit 20 to the apparatus 10 will be described hereinafter.
At this time, it is sufficient to state that the control unit 20 is conventional and
that it has: a read only memory (ROM) 22; random access memory (RAM) 24; a processor
(MP) 26; the keyboard (KB) 14 for entering data; a display 16 for communicating with
an operator; an interface 28 for coupling the control unit 20 to other components
to be described; and interface and control logic 31 to connect the various elements
of the control unit 20. The various programs or routines for controlling the operation
of the control unit 20 and the system 10 may be stored in the ROM 22 or loaded daily
into the RAM 24 to enable the control unit 20 to function as what is generally referred
to as an "intelligent" processor or terminal.
[0014] In using the system 10 shown in Fig. 1, an operator, for example, picks a document
30 from the stack 32, reads the courtesy amount from the document, enters the amount
and other conventional control data on the keyboard 14, and thereafter, hand drops
the document 30 into the document track 34, shown schematically in Fig. 3. The document
30 is moved in the track 34 where the encoder components 18 perform the encoding of
the courtesy of monetary amount on the document mentioned and also perform the bank
stamping functions mentioned. After encoding and stamping, the document 30 is transferred
to the apparatus 12 where the document may be pocketed in one of the pocket members
(#1 through #6) of the group 36 (Fig. 4).
[0015] One of the features of the present invention is that the free-standing apparatus
12 may be modular in construction, and multiple units of the apparatus 12 can be assembled
in side-by-side relationship to increase the associated, pocketing capacity of the
system 10. For example, the apparatus 12 has an entry port 38 (Fig. 3) which is aligned
with the exit port 40 of the document track 34 to receive the documents 30 from the
system 10. The apparatus 12 also has an exit port 42 and a document transporting track
44 which connects the input and output ports 38 and 42. A conventional selector 46
is positioned relative to the track 44 to assume two different positions with regard
to the track 44. In a first or actuated position, for example, the selector 46 deflects
a document 30 out of the track 44 and directs it to a transfer station designated
generally as 48. In the second position, the selector is spring biased to an inoperative
position so that documents 30 will not be pocketed but will pass to the exit port
42 of apparatus 12.
[0016] The transfer station 48 (Fig. 3) includes first and second means for receiving a
document 30 therebetween; these first and second means will be referred to conveniently
as first and second track members 51 and 52, respectively, and they are shown only
schematically in Fig. 3. In the embodiment described, the documents, like 30, are
moved on their long, lower edges, and they are moved in a generally-horizontal direction
when they are moved from the track 34, to the track 44 (Fig. 3), and to the transfer
station 48. At the transfer station 48, means (to be later described) are provided
to move the documents in a downwardly, vertical direction to the various pocket members
36 (shown within a bracket) which pocket members are individually numbered from #1
to #6 in Fig. 4. The selection of the individual pockets #1 to #6 in which the documents,
like 30, are to be pocketed is controlled by the control unit 20 shown in Fig. 2.
Certain control data on the documents themselves or the control data entered at the
keyboard 14 may be used to provide the pocket destinations for the documents.
[0017] As previously stated, the construction of the apparatus 12 is modular, so that if
more than six pockets are required in the system 10, an identical apparatus 12-1 is
provided as shown in Fig. 3. The same basic number in apparatus 12-1 is used to describe
a corresponding part already described in relation to apparatus 12, however, a "dash
one" (-1) designation is given to the part in apparatus 12-1. For example, the transfer
station 48-1 in apparatus 12-1 is identical to transfer station 48 in apparatus 12.
[0018] With this modular construction, if an encoded document 30 is to be routed to pocket
#4 of pockets 36-1 (Fig. 4) of the apparatus 12-1, for example, the control unit 20
(Fig. 2) will issue the appropriate control (if necessary) to position the selector
46 (Fig. 3) in the second position, permitting the document to move in track 44, out
the exit port 42 of apparatus 12, and into the track 44-1 of apparatus 12-1. The control
unit 20 will also issue the appropriate control to position the selector 46-1 of the
apparatus 12-1 in the first position to deflect the document to the transfer station
48-1. From there, the document 30 will be moved downwardly and directed into pocket
member #4 of the group 36-1 as previously described.
[0019] In the example described, it is the control unit 20 of the system 10 which controls
the operation of the apparatuses 12 and 12-1; however, other control arrangements
could be utilized. If more than the two apparatuses 12 and 12-1 are required for pocketing
capacity, additional such apparatuses may be added to the system 10.
[0020] Having described, generally, the functioning of the system 10 and the apparatus 12,
it appears appropriate to discuss the details of the apparatus 12. In this regard,
Figs. 5A and 5B, taken together, depict a plan view of the portions of the apparatus
12 already described in relation to Fig. 3. Certain panels and covers, not shown and
not important to this invention, are removed to facilitate a showing of the apparatus
12. Also, certain of the elements included in Figs. 5A and 5B are shown schematically
to simplify these figures.
[0021] In Fig. 5A, a document 30 is shown entering (on its long, lower edge) the entry port
38 of the apparatus 12. Only a portion of the document 30 is shown; however, the document
is being transferred from the encoder components 18 (Fig. 1) of the system 10. The
apparatus 12 is detachably secured to the system 10 by suitable interlocking members
shown only schematically as pins 54 and 56. The apparatus 12 also includes leveling
screws 55 and 57 (Fig. 4) to enable it to be adjustably positioned relative to the
system 10 to align the entry port 38 of the apparatus 12 with the exit port 40 of
the system 10 to provide for a smooth transfer of documents therebetween.
[0022] The document track 44 (Fig. 5A) connects the input port 38 and the exit port 42 (Fig.
3) as previously explained. The track 44 is comprised of a first wall section 44-2
(upstanding from a base 58) and a second wall section 44-3 upstanding from its base
60. The sections 44-2 and 44-3 are spaced apart to receive the document 30 therebetween.
The bases 58 and 60 are secured to a planar support 62 of the apparatus 12 by fasteners
64 and 66, respectively. The selector 46, alluded to earlier herein, is shown in the
diverting position in Fig. 5A. The selector 46 is comprised of a curved wall 68 which
is approximately a quarter of a circle and which is upstanding from and secured to
the plate 70. The plate 70 is fixed to rotate with the driving shaft 72.which is rotatably
supported in the planar support 62. An actuator, such as a rotary solenoid 74, is
operatively coupled to the shaft 72 by linkage shown as dashed line 75, to rotate
the shaft 72 in a clockwise direction (as viewed in Fig. 5A) to the position shown
whenever the solenoid 74 is energized in the embodiment described. When the solenoid
74 is de-energized, a separate spring of a solenoid-contained spring (neither spring
is shown) associated with the solenoid 74 rotates the shaft 72 and the selector 46
in a counter-clockwise direction to the second position mentioned. In the second position,
the upstream edge 76 of the curved wall 68 is positioned behind the trailing edge
78 of the inlet port 38 to provide an obstruction-free path for documents to be transferred
from the inlet port 38 to the exit port 42. Correspondingly, when the selector 46
is in the first position shown in Fig. 5A, the upstream edge 76 of the curved wall
68 is positioned behind the trailing edge 80 of the inlet port 38 to facilitate the
smooth transporting of documents to the transfer station 48.
[0023] The means for moving the documents from the inlet port 38 to the exit port 42 of
the apparatus 12 are conventional and include the driven roller 82 (Fig. 5A), the
idler rollers 84 and 86, and the associated back-up or pinch rollers 92, 88 and 90.
An endless flat belt 94 partially encircles the driven roller 82 and the idler roller
84, and it passes in front of the idler roller 86. These rollers and the belt 94 are
positioned relative to the track 44 so that the belt extends slightly into the space
between the track walls 44-2 and 44-3. The associated pinch rollers 88, 90 and 92
are resiliently biased towards the center of the track 44 and are substantially aligned
with rollers 84, 86 and 82, respectively, to cooperate with the moving belt 94 to
move the documents 30 towards the exit port 42. The belt 94 is located horizontally
in the track44 at a height (above the track floor) equal to about half the height
of the documents 30 being transported thereby.
[0024] The means for moving the documents 30 in the track 44 also include the motor 96 whose
output pulley 98 (Fig. 5A) is connected to a tandem drive pulley 100 by a belt 102
shown as a dashed line. The tandem drive pulley 100 is also coupled to driven pulley
82 by a driving belt 104 which is shown as a dashed line.
[0025] When a document 30 is selected or deflected towards the transfer station 48 (Figs.
5Aand 5B), as previously described, there is provided a first means designated generally
as 106 for moving the selected document 30 in a first direction to the transfer station
48. Thereafter, a second means designated generally as 108 for moving the document
30 is used to move the document 30 in a second direction (downwardly, as viewed in
Fig. 4) to the group of pockets 36.
[0026] The first moving means 106 (Figs. 5A and 5B) includes a roller 109 which is operatively
driven in a counter-clockwise direction (as viewed in Fig. 5A) by the tandem pulley
100 previously mentioned. The first moving means 106 also includes a flat belt 110
which is mounted on the rollers 109 and 112, and which belt passes in front of rollers
114, 116, 118 and 120, as shown in Fig. 5B. The spaced, pinch rollers 122,124,126,128
and 130 are aligned with the rollers 112,114,116,118 and 120, respectively, to resiliently
bias the document 30 into engagement with the flat belt 110 to enable the document
to be moved in the first direction mentioned. The first direction with reference to
the transfer station 48 means that the document 30 moves between the first and second
track members 51 and 52 towards the reader when looking at Fig. 8. Plate 132, which
is oriented in a horizontal direction in Fig. 8 in the embodiment described, should
help to orient the reader. The document 30 has to be supported between the rollers,
like 128 and 118 and the belt 110, along the length of the transfer station 48 because
there is no "bottom" (in the normal sense) to the transfer station. There is no "bottom"
in order to facilitate the transfer of documents from the first direction to the second
direction which, in Fig. 8, is downwardly along the direction of arrow 134.
[0027] Before a document 30 is moved in the second direction mentioned, the document is
moved at a constant velocity by the first drive means 106 in the first direction towards
the front drawer panel 136, shown in Fig. 5B. As the leading edge of the document
30 approaches the drawer panel 136, it encounters a conventional, light-and-sensor
detector 138 which produces a stop signal which is forwarded to the control unit 20
(Fig. 2).
[0028] In response to the stop signal, the control unit 20 energizes solenoid 140 (Fig.
8) and simultaneously energizes solenoid 142 (Fig. 5B) to produce two separate activities
to be described hereinafter.
[0029] When solenoid 140 is energized, it pivots the first track member 51 in a counter-clockwise
direction (as viewed in Fig. 8) about pivot point 144 (shown as a screw) to the position
shown in dashed outline as 51-3. The point 144 is fixed relative to a frame 146 which
is shown only schematically in Fig. 8; this aspect will be discussed hereinafter.
When the first track member 51 is moved to the position shown by dashed outline 51-3,
the pinch rollers 122,124,126,128 and 130, which are supported on the first track
member 51, are moved away from and out of operative engagment with the moving belt
110 which is mounted on the second track member 52, thereby ceasing to positively
drive the document 30 in the first direction towards the front drawer panel 136. Even
though the positive driving of the document 30 is stopped, it has momentum which carries
it towards a spring 148 (Fig. 5B) which decelerates and stops the document. The spring
148 is at least an inch wide, is made of thin, sheet steel, and has the general shape
shown in Fig. 5B in which top edge of the spring is seen. The spring 148 has a first
portion 150 which projects into the space between the first and second track members
51 and 52 (to decelerate a document 30 without damaging the leading edge thereof),
and it also has a hook portion 152 on the end thereof. A light document 30 is decelerated
and stopped generally by the first portion 150, and a heavier, card-like document
30 is decelerated by the first portion 150 of the spring 148 and stopped by the hook
portion 152 thereof. The hook portion 152 of the spring 148 is located in a vertically-aligned
recess 154 which provides clearance for the leading edge of a document as it is moved
in the second direction or downwardly as viewed by arrow 134 in Fig. 8.
[0030] As alluded to earlier herein, the second moving means 108 is used to move a document
30 in the second direction or downardly as shown by arrow 134 in Fig. 8 as just stated.
The second moving means 108 includes a plurality of rollers shown as roller group
156, a plurality of spaced, longitudinally-aligned belts shown as belt group 158,
a plurality of gliding blocks shown as block group 160, and a plurality of pinch rollers
shown as pinch rotter group 162. Before describing all the details of the second moving
means 108, it appears appropriate to discuss, first, its general operation.
[0031] The activity which ensued when solenoid 140 was energized was described earlier herein,
and when solenoid 142 is energized therewith, the following activities occur. When
the solenoid 142 is energized, it moves the pinch rollers of the roller group 162
(Fig. 8) towards the belts of belt group 158 to resiliently bias a document 30, towards
and into engagement with the belts of the belt group 158. The first track 51 has a
plurality of spaced, parallel fingers shown as finger group 164 which are positioned
to be located close to the second track 52 when the first track member 51 is in the
solid position shown in Fig. 8; however, when the solenoid 140 is energized to move
the first track member 51 to the position shown in dashed outline 51-3, the finger
group 164 recedes away from the second track member 52 to expose the belts of the
belt group 158. The pinch rollers of the roller group 162 then move the document 30
into engagement with the belts of the belt group 158, which belts then move the document
downwardly in the second direction as shown by arrow 134. As the document 30 is moved
downwardly by the belt group 158, the bottom, long edge of the document 30 engages
the blocks of the block group 160, which cooperate with the belts of the belt group
158 to further drive the document downwardly to be directed to one of the pocket members
of the group of pocket members 36 by the control unit 20. Thereafter, the solenoids
140 and 142 are de-energized by the control unit 20, permitting resilient means (to
be later described) to return the first track member 51 to the home position shown
in solid outline in Fig. 8 and to return the pinch rollers of the pinch roller group
162 from the active position shown in Fig. 8 to a home position which is located to
the right of the position shown. This movement clears the rollers of group 162 from
the space between the first and second track members 51 and 52 and permits the next
succeeding document 30 to be moved freely in the first direction before being moved
downwardly in the second direction as just described.
[0032] Having described the general operation of the apparatus, it appears appropriate to
discuss additional details about the first track member 51. As previously alluded
to, the first track member 51 is pivotally supported on point 144. Actually, there
is an additional point 144-1 (Fig. 9) which is aligned with pivot point 144. The frame
146 shown only schematically in Fig. 8 includes the frame member 146-1 having an offset
flange 146-2 (Fig. 10) which is secured to frame portion 146-3 by fasteners like 166.
The frame member 146-1 also has the offset portions 146-4 and 146-5 which provide
the support for the pivot points 144 and 144-1, respectively. The frame member 146-1
also includes an offset portion 146-6 (Fig. 9) to which the solenoid 140 is secured.
[0033] The first track member 51 is pivotally supported on the frame member 146-1 (Fig.
10) by the levers 168 and 170. One end of lever 168 is pivotally mounted on the offset
portion 146-4 by a fastener whose longitudinal axis represents the pivot point 144.
The remaining end of lever 168 is fastened to the first track member 51, by the fasteners
172. Similarly, one end of lever 170 is pivotally mounted on the offset portion 146-5
(Fig. 9) by a fastener whose longitudinal axis represents the pivot point 144-1 which
is aligned with pivot point 144. The upper end of lever 170 has a first offset portion
(not shown) which enables the lever 170 to be secured to the first track member 51
by fasteners similar to fasteners 172 already discussed in relation to the lever 168,
and the lever 170 also has a second offset portion 170-1 (Fig. 9). A "U-shaped" channel
member 174 is secured to the offset portion 170-1 by fasteners 176 and 178. The channel
member 174 has a short, high wall section 180 and a narrower, longer, wall section
182 as seen best in Fig. 9; the member 174 is not shown in Fig. 8 to simplify that
figure. A limiting pin 184 (Fig. 10) is mounted on the offset portion 146-6 of the
stationary frame member 146-1 so as to abut against the wall section 180 as will be
described hereinafter, and a compression-type spring 186 is mounted on the pin 184
between the offset portion 146-6 and the wall section 180. The pin 184 limits the
pivoting movement of the first track member 51 in the counter-clockwise direction
(as viewed in Fig. 10) to the position shown as 51-3 in Fig. 8. The compression-type
spring 186 biases the first track member 51 to the home position or the position shown
in solid outline in Fig. 8. When the solenoid 140 is energized as previously described,
the operating plunger 188 of the solenoid engages the wall section 182 of the channel
member 174 to pivot the first track member 51 in the counter-clockwise direction (as
viewed in Figs. 8 and 10) against the bias of spring 186 to the position shown in
dashed outline 51-3 shown in Fig. 8. When the solenoid is de-energized, the spring
186 (Fig. 10) returns the first track member 51 to the home position.
[0034] Having described how the first track member 51 (Figs. 8, 9, 10) is mounted for pivotal
movement on the frame 146, it appears appropriate to discuss how the frame 146 is
mounted within the apparatus 12. It should be recalled from the earlier discussions
herein that the first track member 51 is moveable in the first direction to an extended
position shown in Figs. 6 and 7 to facilitate the removal of a jammed document 30
or documents from the transfer station 48 (Fig. 5B). In this regard, the frame 146
is conventionally mounted on four, ball bearing slides 190, 192, 194 and 196, which
are coupled to the apparatus 12 and the frame 146 to enable the frame 146, with the
first track member 51 thereon, to be moved (in drawer-like fashion) out of the apparatus
12 as shown in Figs. 6 and 7 and to be returned to the operative position shown in
Figs. 5A and 5B, for example. A suitable latch (not shown) keeps the frame 146 in
the operative position shown in Figs. 5A and 5B. Notice that when the frame 146 is
pulled out to the pulled-out position shown in dashed outline in Fig. 6, any document
30 which was jammed at the transfer station 48 can be reached readily to unjam or
dislodge it. Also, when the frame 146 is pulled out of the apparatus 12, any document
30 which might jam in any one of the selectors associated with the pockets of the
pocket members 36 is readily accessible for removal.
[0035] Continuing with a discussion of the first track member 51, the fingers associated
with the finger group 164, which were alluded to with regard to the discussion of
Fig. 8, are shown in more detail in Fig. 9. The fingers 164-1, 164-2, 164-3, 164-4,
164-5,164-6 and 164-7 of the finger group 164 are spaced apart as shown so as to receive
therebetween the rollers 156-1 (Fig. 6), 156-2, 156-3, 156-4, 156-5 and 156-6 (not
shown) of the roller group 156, alluded to with regard to the discussion of Fig. 8.
As previously stated, when the first track member 51 is in the home position shown
in Fig. 8, the fingers 164-1 through 164-7 extend into the space between the track
members 51 and 52 to keep the belts of the belt group 158 from interfering with the
advancement of a document 30 in the first direction as previously described. The belts
of the belt group 158 are driven by a motor 198 (Fig. 7) which is mounted on the frame
146 to move therewith. The output pulley 200 of the motor 198 is drivingly coupled
to a driven pulley 202 by a belt shown only as dashed line 204. The pulley 202 rotates
the shaft 206 which is rotatably mounted between the side frames 208 and 210 of the
frame 146. There are six spaced, drive rollers 206-1, 206-2, 206-3, 206-4, 206-5 and
206-6 which are secured to the shaft 206 to rotate therewith, and the individual endless
belts 158-1, 158-2, 158-3, 158-4, 158-5 and 158-6 of the belt group 158 are mounted,
respectively on these drive rollers. At the upper end of the belt group 158, the endless
belts 158-1, 158-2, 158-3, 158-4, 158-5 and 158-6 are mounted on the rollers 156-1
(Fig. 6), 156-2, 156-3, 156-4, 156-5 and 156-6 (not shown) to simplify the drawing),
respectively, and these named rollers are rotatably mounted on a shaft 212 which is
rotatably mounted in the side frames 208 and 210. As an alternative, the rollers 156-1
through 156-6 may be fixed to shaft 212 to rotate therewith, and the shaft 212 may
be positively driven by a drive pulley and timing belt (not shown) which are conventionally
and operatively coupled to the output pulley 200 of motor 198 (Fig. 6). The belts
of the belt group 158 are driven downwardly at the transfer station 48 as shown by
arrow 134 in Fig. 8. There are rods 216 and 220 positioned between the driving shaft
206 and the shaft 212 as shown in Fig. 7. Rod 216 has rollers 216-1 through 216-6
rotatably mounted thereon with only rollers 216-1 and 216-6 being marked thereon to
simplify the drawing. Similarly, rod 220 has rollers 220-1 through 220-6 rotatably
mounted thereon, with only rollers 220-1 and 220-6 being marked thereon to simplify
the drawing. These rods 216 and 220 with the corresponding rollers (as just identified)
thereon, are used to force the document into sliding engagement with the blocks of
block group 160 to thereby move the document 30 towards the pockets of the group 36
of pockets as previously described. While looking at Fig. 7, it should also be noted
that there are six selector shafts 214-1, 214-2, 214-3, 214-4, 214-5, and 214-6 which
are pivotally mounted between the side frames 208 and 210; these shafts are pivoted
slightly when the associated solenoids 218-1, 218-2, 218-3, 218-4, and 218-5 (Fig.
11) are energized. The solenoids 218-1 through 218-5 are energized by the control
unit 20 to divert a document into the associated pocket #1 through #5 (Fig. 4) of
the group 36 of pockets. The bottom most shaft 214-6 does not need a solenoid to actuate
it because any document 30 which is not selected by the actuation of solenoids 218-1
through 218-5 will go into the last pocket #6. This aspect will be discussed later
herein.
[0036] Part of the second means 108 for moving a document 30 in the second direction (according
to arrow 134 in Fig. 8) includes the blocks of the block group 160. In this regard,
Fig. 12 shows a line 160-1 of blocks included in the block group 160, and the remaining
lines 160-2, 160-3, 160-4, 160-5, and 160-6 of blocks included in group 160 are shown
in Fig. 7. The lines 160-1 through 160-6 are all identical; therefore, a discussion
of the line 160-1 of blocks shown in Fig. 12 will suffice.
[0037] The line 160-1 of blocks (Fig. 12) includes a plurality of identical blocks 222-1,
222-2, 222-3, 222-4, 222-5, 222-6 and 222-7 in spaced, aligned relationship, with
only blocks 222-1 and 222-2 being shown in Fig. 12. The blocks, like 222-1 and 222-2,
are spaced apart to receive therebetween a belt, like 158-1, of the belt group 158.
In the embodiment described, the line of blocks 160-1 is formed of plastic material
of about three millimeters thick, with the blocks being formed thereon generally like
the "blisters" on "blister packages". The block 222-1 has a top side 224, a sloping
side 226, a front side 228, and a lower side 230 as shown in Fig. 12.
[0038] Fig. 13 is a schematic diagram which is taken along the general line 13-13 of Fig.
12 to show how a document 30 assumes a general, corrugated shape as it is moved downwardly
along arrow 134 (Fig. 8) as previously alluded to. Fig. 13 is not drawn to scale,
and it is exaggerated to show how the rollers 156-1 through 156-6 of the roller group
156 are positioned relative to the line of blocks 160-1, for example, to cause the
document 30 to assume the corrugated shape' mentioned. The sloping side 226 of the
blocks, like 222-1, is used to direct the document 30 towards the belts of the belt
group 158, and the document is supported between the front side 228 and the belts,
like 158-1 and 158-2, of the belt group 158 in the example described, as the document
is moved downwardly.
[0039] As a document 30 is moved downwardly, as shown by arrow 134 in Fig. 14, it approaches
a plurality of lines of vertically-aligned selectors or diverter lines like lines
232-1 and 232-2 which have the general outline shown. The diverter line 232-1 is associated
with pocket #1, and similarly, diverter lines 232-2, 232-3, 232-4, 232-5, and 232-6
(Fig. 7) are associated, respectively, with pockets #2 through #6. As seen in Fig.
7, each line of diverters, like 232-2, includes the diverters D1, D2, D3, D4, D5,
D6, and D7 which are aligned with the blocks of the line of blocks like 160-2, for
example. This construction enables the long, lower edge of a document 30 to be selected
or diverted into the appropriate pocket #1 through #6. The diverters D1 through D7
are fixed to a square shaft like 214-2 (Fig. 14) to rotate therewith. The shaft 214-2
is coupled to the solenoid 218-2 (Fig. 11 and when a document 30 is to be routed to
pocket #2, for example, the line 232-2 of diverters (Fig. 14) is rotated in a counterclockwise
direction (as viewed in Fig. 14) by energizing solenoid 218-2 to cause the document
to be diverted towards pocket #2 to fall therein. Energization of the appropriate
solenoids 218-1 through 218-5 is effected by the control unit 20 to divert the documents
as previously described. A separate spring (not shown) associated with each of the
solenoids 218-1 through 218-5 is used to return the line of diverters, like 232-2,
to the home position shown in Fig. 14. The line 232-6 of diverters (Fig. 7) may be
permanently positioned in the diverting position to divert the documents into pocket
#6 because it is the last pocket in the line of pockets, and consequently, an operating
solenoid; like 218-5, is not needed for the line 232-6 of diverters. The belts of
the belt group 158 have a high coefficient of friction when compared to the low coefficient
of friction of the blocks of the block group 160; this enables the documents 30 to
be positively driven downwardly by the belts.
[0040] As the documents 30 accumulate in the pockets #1 through #6 (Fig. 14) in a typical
pocketing operation, the levers 236-1 through 236-6 (only levers 236-1 and 236-2 are
shown) associated with pockets #1 through #6 begin to rotate in a counter-clockwise
direction (as viewed in Fig. 14) about their associated pivot blocks, like 238-1 and
238-2. When a pocket, like #1, approaches the full level, a magnet 240-1 on the end
of lever 236-1 coacts with a detector, like 242-1, to produce a "full" signal which
indicates to the control unit 20 that the pocket #1 is full. In the embodiment described,
the detector 242-1 is a Hall-effect detector. Each of the remaining levers 236-2 through
236-6 has a magnet (not shown), like 240-1, on the end thereof, to cooperate with
the associated detectors 242-2 through 242-6 of the pockets #2-#6. The detectors 242-1
through 242-6 are shown collectively as 242 in Fig. 2.
[0041] Each pocket #1 through #6 (Fig. 14) has a document present detector 244-1 through
244-6 (shown collectively as 244 in Fig. 2) associated respectively therewith, to
give a "present" signal to the control unit 20 whenever a document 30 enters the associated
pocket. The control unit 20 has conventional routines stored in its ROM 22 or RAM
24 to monitor the elapsed time between detecting the leading edge of a document 30
at detector 138 (Fig. 5B) located at the transfer station 48 and detecting the presence
of the document 30 at one of the document present detectors 244-1 through 244-6. If
a document 30 does not arrive at its intended selected pocket within a predetermined
elapsed time, the control unit 20 indicates to the operator that a possible document
jam has occurred by giving an indication on the display 16, for example. The movement
of documents 30 between the apparatus 12 and apparatus 12-1, for example, can be similarly
monitored.
[0042] Fig. 15 is an end view of the second track member 52, and it is used to show how
the pinch rollers of the pinch roller group 162 (Fig. 8) are moved into operative
engagement with the longitudinally-aligned belts of the belt group 158. One pinch
roller 162-1 through 162-5 is provided for aligned, opposed relationship with one
of the rollers 156-1 through 156-5 (Fig. 6) as previously discussed, although only
roller 162-1 is shown in Fig. 15. Roller 162-1 is mounted on one end of a cantilever-type,
flat spring 246 whose remaining end is secured to a mounting bar 248 which extends
along the length of the second track member 52. The bar 248 is pivotally mounted on
frame ends 252 by the mounting rods 250 which extend from the bar 248. A camming lever
254 has one end thereof secured to the bar 248, and the remaining end thereof has
one end of a tension spring 256 secured thereto. The remaining end of the spring 256
is secured to a stationary support 258 which is secured to a flange 260 of the second
track member 52. When the solenoid 142 is energized, its plunger 262 pivots the camming
lever 254 (and the bar 248) in a clockwise direction (as viewed in Fig. 15) about
the rods 250 (as a pivoting axis) to thereby move the pinch rollers of roller group
162 from the inoperative position shown in Fig. 15 to the operative position shown
in Fig. 8. When the solenoid 142 is de-energized, the spring 256 returns the roller
group 162 to the home or inoperative position shown in Fig. 15.
[0043] Some miscellaneous points need to be mentioned. A brush 264 (Fig. 5A) which is located
at the entrance to the transfer station 48 is used to minimize static electricity
associated with moving the documents 30. The rollers, like 88 (Fig. 5A) pass through
aligned slats in the curved wall 226 which functions as a guide to direct documents
30 toward the transfer station 48 as previously described. A conventional test circuit
268 (Fig. 2) which is part of the apparatus 12 may be used to test certain functions
of the apparatus as is done, conventionally.
