Abstract
A depositor accommodating substantially thicker deposits than was possible with prior systems. A pair of plates each having a transport mechanism disposed as part thereof are coupled to a housing so as to abut each other, one above the other, in a rest position. A drive shaft for the transport mechanisms of the upper and lower plates are rotatably coupled to the housing and define an axis of rotation for each plate. The drive shaft for the top plate is disposed at an opposite end from the drive shaft of the bottom plate. A free end of each plate, the end opposite the drive shaft, is elastically coupled to the housing. This allows a substantially thicker deposit envelope to be accepted than was possible with prior systems.
Description
BACKGROUND OF THE INVENTION
(1) Field of the Invention
The invention relates to a mechanism for accepting customer deposits. More specifically, the invention relates to an automated depositor which can receive customer deposits of bundles of cash and/or checks of widely varying thicknesses and with reduced maintenance.
(2) Related Art
Automated depositors have been widely used in the banking industry for many years. Depositors are typically incorporated into automatic teller machines (ATMs), which provide other after hours banking services in addition to those provided by the depositor. Prior art depositors typically have a front gate which covers a deposit receiving opening or mouth of the depositor. The gate is typically driven by a solenoid which, in turn, is activated responsive to the deposit request by a customer. When the gate opens, it exposes through the opening an upper and lower plate, one of which typically includes a drive belt which frictionally engages the envelope to be deposited. The plate with drive belt is typically fixed within the depositor and does not move regardless of the thickness of the envelope, e.g., the deposit, being deposited. The other plate typically floats so as to maintain pressure between itself and the envelope and, therefore, the drive belt and the envelope. In such case, the floating plate is smooth so as to reduce the probability of a jam caused by the envelope sticking on the floating plate.
The maximum float of the floating plate has typically been about one quarter inch. Thus, these prior art depositors typically only accommodated deposit envelopes having a maximum thickness of about a quarter of an inch. This is a major shortcoming in view of the fact that the deposits of many customers, particularly businesses, are typically in the range of a quarter of an inch to one inch. Moreover, it is often not convenient for businesses to make their deposits during normal banking hours, nor is it convenient for them to have to split the deposits into multiple deposits of a quarter inch or less in order to complete the daily deposits outside of banking hours.
Prior art depositors also include printing devices such as a dot matrix printer or an inkjet printhead disposed within the depositor to allow printing on the envelope being deposited. This allows the bank to identify the deposit by an account number and conduct the transaction with minimal employee time. The printing is particularly important as physical deposit slips with account numbers are typically no longer included with the deposit. The print mechanisms suffer a number of problems. Residual ink often clogs the jetports of the inkjet printer and results in illegible printing. In some cases, the printer could not process the data or print it during the limited exposure as the envelope is driven under the printhead. Either case results in wasted employee time matching an account to the items being deposited.
In view of the foregoing, it would be desirable to develop a depositor that accommodates a broader range of deposit thicknesses within improved printing reliability.
BRIEF SUMMARY OF THE INVENTION
A depositor accommodating thick deposits is disclosed. A pair of plates each having a transport mechanism disposed as part thereof are coupled to a housing so as to abut each other, one above the other, in a rest position. A drive shaft for the transport mechanisms of the upper and lower plates are rotatably coupled to the housing and define an axis of rotation for each plate. The drive shaft for the top plate is disposed at an opposite end from the drive shaft of the bottom plate. A free end of each plate, the end opposite the drive shaft, is elastically coupled to the housing. This allows a substantially thicker deposit envelope to be accepted than was possible with prior systems.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1
is a right side view of a depositor of one embodiment of the invention with the right housing cover removed. A motor
1
is provided and coupled to housing
6
. The motor
1
drives timing belt
2
which in turn directly drives drive shaft
21
and pulley
3
. Timing belt
2
indirectly drives drive shaft
11
via pulley
3
and a gear assembly (not shown). The drive shafts
11
and
21
are rotatably coupled to housing
6
. This rotatable coupling can be accomplished using bushings or other similar known technique. Drive shafts
11
and
21
drive the transport mechanisms of upper plate
10
and lower plate
20
, respectively. One possible transport mechanism is one or more belts that surround drive shafts
11
and
21
wherein the belts are able to frictionally engage a depositable item. Spring
22
couples the lower plate
20
to the housing
6
at a connection point
80
. Similarly, spring
12
elastically couples the upper plate
10
to the housing
6
at a connection point
70
. A front gate
5
is coupled to the housing
6
and covers a mouth of the depositor when the depositor is installed in, for example, an ATM assembly.
FIG. 2
is a left side view of depositor
FIG. 1
with the left housing cover removed. Micromotor
8
is coupled to a housing
6
and drives linkage
9
to open gate
5
responsive to initiation of a deposit request. The micromotor
8
improves control and response over the prior art solenoid opening techniques. Gear assembly
7
allows motor
1
to drive drive shaft
11
such that drive belts (not shown) on plates
10
and
20
drive in the same direction. One such gear assembly includes a gear, a bearing and a shaft.
FIG. 3
is a top plan view of upper plate
10
in one embodiment of the invention. Longitudinal members
14
support drive shaft
11
and a plurality of follower shafts
17
. Two long drive belts
13
are disposed on pulleys
18
of opposing sides of the longitudinal members
14
. A pair of short belts
15
and
16
are disposed between longitudinal members
14
and coupled to the drive and follower shafts by pulleys
18
. A space is provided between front short belt
15
and rear short belt
16
in which print mechanism
19
is disposed. Anti-fishing hooks
32
are coupled to drive shaft
11
using a torsion spring
36
. A first envelope sensor
31
is provided adjacent to short belt
15
, while a second envelope sensor
33
is provided adjacent to short belt
16
. The envelope sensors
31
,
33
indicate when the deposit envelope has passed thereunder such that the gate
5
may be closed or a deposit accepted notification sent to the customer. Short belt
16
is offset, e.g., not co-linear with short belt
15
. This allows accommodation of sensor
33
, as well as clearing the print path such that no contact exists between the tray
10
and the print on the envelope created by print mechanism
19
. It is important to minimize or eliminate contact with the printed surface to allow the ink the opportunity to dry without smearing.
FIG. 4
is a sectional side view of the top plate of FIG.
3
. Print mechanism
19
has printhead
34
disposed so as to be a predetermined distance from an envelope transported by the various drive belts, including short belts
15
and
16
. This distance is maintained because the printhead floats with the plate. Upper plate
10
can pivot about an axis defined by drive shaft
11
, but is restrained in a rest position by springs
12
(shown in FIG.
1
). Thus, opposing end
50
can move in an upward arc above that pivot point, but the force exerted by springs
12
increases with displacement in accordance with Hooke's law. One or more stops (not shown) may be provided to ensure pivoting does not occur outside a maximum desired range. The pivoting of upper plate
10
and corresponding lower plate
20
occurs as a result of wedge action of a deposit envelope (described below). Accordingly, the springs
12
and
22
should be selected with sufficiently low spring constraints that within an established acceptable range, the resulting friction between plate
10
and plate
20
and the envelope will not over tax the motor
1
or result in a jam. The torsion spring
36
(as shown in
FIG. 3
) which the anti-fishing hook
32
is coupled to drive shaft
11
acts against the floor
37
of the plate
10
.
FIG. 5
is a plan view of the lower plate of one embodiment of the invention. Lower plate
20
has several structures corresponding to those found in the top plate. Specifically, lower plate
20
has a drive shaft
21
which drives two long drive belts
23
and two short drive belts
25
and
26
. The belts are supported by pulleys coupled to drive shaft
21
and follower shafts
27
. Significantly, drive shaft
21
is in the lower plate, the rear most shaft where the location of the front gate is defined to be the front. Similar to upper plate
10
, lower plate
20
pivots about an axis defined by its drive shaft
21
. Notably, this means that the front side of the lower plate
20
pivots, while the rear side of upper plate
10
pivots. Having effectively two floating plates, greater widths of deposit envelopes can be accommodated. In a preferred embodiment, the float of the upper plate
10
and lower plate
20
relative to each other allows deposit envelopes of up to one inch thickness to be deposited.
Lower plate
20
also includes a maintenance station
29
positioned so as to reside in a predetermined relation to the print mechanism
19
of the upper plate. The maintenance station
29
(described more fully with reference to
FIGS. 6
a
and
6
b
below) is positioned between short belt
25
and short belt
26
of lower plate
20
. The maintenance station is driven by a micromotor
35
coupled to the lower plate.
FIG. 6
a
shows a maintenance station
29
in a capping, or inactive, position. A cam
45
is driven by the micromotor
35
to cause the wiper
41
and capping cup
42
to move through a predetermined arc. The wiper
41
clears residual ink from the printhead when it is driven over the printhead
33
in preparation for printing and following completion of a print. These periodic wipings of the printhead
33
reduce the probability of print malfunctions due to clogs of the inkjets. Additionally, the capping cup
42
which is disposed so as to cap the printhead when no deposit is occurring, decreases the air exposure of the printhead
33
and thereby makes it less likely for the printhead
33
to dry up. A spring
43
applies pressure on the lower side of the capping cup holding it in place. A stop
44
is provided to prevent the overrotation of the wiper capping cup assembly.
FIG. 6
b
shows the maintenance station
29
in the printing (deposit accepting) position. In this position, the micromotor
35
has rotated the capping cup
42
90° such that it does not prevent passage of an incoming envelope. When the sensor
33
detects the envelope has passed, e.g., the deposit is accepted, the micromotor
35
rotates the capping cup
42
back into the capping position.
FIG. 7
is a sectional right side view of the depositor of one embodiment of the invention. As previously discussed, front gate
5
is opened responsive to a deposit request. Opening of gate
5
exposes mouth
70
into which a deposit envelope may be inserted. At the time the gate
5
opens, the drive belts
13
and
23
, as well as a short drive belt (not shown), will already be being driven by the motor by drive shafts
11
and
21
, respectively. The belts will, therefore, frictionally engage an inserted envelope drawing it into the depositor. The envelope will then serve as a wedge causing each plate to rotate about its axis of rotation along its respective drive shaft
11
or
21
. A maximum rotation is constrained by stops
51
for the upper plate
10
, and
61
for the lower plate
20
. Notably, each plate rotates independently of the other plate. The displacement of each plate is related to the location of the envelope relative to the axis of rotation. Once the sensor
31
detects that the envelope is completely inside, the front gate
5
can be driven closed. The drive belts
13
,
15
,
16
,
23
,
25
, and
26
will drive the envelope under the printhead
33
which will print a string of information on the envelope identifying the account and amount of the deposit. The envelope will then proceed across the plates and fall under the influence of gravity into a bin (not shown), thus, concluding the deposit.
In the foregoing specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes can be made thereto without departing from the broader spirit and scope of the invention as set forth in the appended claims. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
