Abstract
A toner loading system for an image forming apparatus includes a valve for a toner bottle and a valve opening member on a toner hopper of the image forming apparatus. The valve includes a first valve member non-rotatably secured to an opening of the toner bottle and a second valve member rotatably secured to the first valve member. The first and second valve members each include tabs and apertures. When the tabs of the first and second valve members are aligned the apertures of the first and second valve members do not overlap and no toner may be dispensed from the toner bottle. The toner bottle is engaged with the valve opening member on the toner hopper to dispense the toner. The valve opening member prevents rotation of the second valve member with respect to the hopper and permits rotation of the first valve member and the toner bottle with respect to the toner hopper. Rotation of the first valve member relative to the second valve member in a first direction causes the tabs to move out of alignment and the aperture of the first valve member to overlap the aperture of the second valve member, allowing dispensing of the toner. The valve opening member prevents disengagement of the toner bottle from the toner hopper while the valve is open, thus preventing spilling of the toner. Rotation of the first valve member relative to the second valve member in a second direction opposite to the first direction moves the tabs back into alignment and closes the valve. The toner bottle may then be disengaged from the valve opening member.
Description
BACKGROUND OF THE INVENTION
1. Field of Invention
This invention relates generally to a system for loading toner in an image forming apparatus.
2. Description of Related Art
In conventional image forming apparatus, toner is used to form an image or images on a sheet or sheets of recording medium. An image forming member, such as a photoreceptor formed of a photosensitive material, is uniformly charged by a charging device. An electrostatic latent image is formed on the image forming member. A developing device supplies toner to the latent image formed on the image forming member to form a toner image.
Toner is supplied to the developing device from a toner source. The toner source may be a toner reservoir or hopper. Toner must be resupplied to the toner hopper when the level of toner in the hopper falls below a specified level. The toner is usually packaged and supplied in bottles or containers having a lid or cap. In order to resupply the toner hopper, the operator must remove the cap of the toner bottle and pour the toner from the bottle into the hopper. The toner often spills from the bottle prior to fitting the bottle opening to the hopper opening. During supply of the toner, the toner bottle must be moved back and forth across the hopper to evenly distribute the toner. During the back and forth movement of the toner bottle, the bottle may disengage from the hopper and toner may spill out of the bottle. The toner may also spill if the operator removes the toner bottle from the hopper before the toner bottle is empty. Even if the bottle is mostly empty, when the operator removes the bottle from the hopper, residual toner may spill or puff out of the bottle and soil the operator, the hopper, and/or the image forming apparatus.
SUMMARY OF THE INVENTION
The toner loading system according to the invention allows loading of toner without removing the cap or lid of the toner bottle. According to various exemplary embodiments the toner loading system, toner bottle and toner hopper according to the invention, the toner loading system includes a toner bottle fitted with a toner bottle valve that controls dispensing of the toner. The toner bottle valve includes a first valve member that is non-rotatably engageable with the opening of the toner bottle. The first valve member includes an aperture for dispensing the toner. A second valve member is rotatably secured to the first valve member and seals the aperture of the first valve member. The second valve member includes an aperture that may overlap the aperture of the first valve member to allow dispensing of the toner from the toner container. The first and second valve members each include a tab. The aperture of the first valve member does not overlap the aperture of the second valve member, and the toner may not be dispensed, when the tab of the first valve member is aligned with the tab of the second valve member.
In various exemplary embodiments of the toner loading system, toner bottle and toner hopper according to this invention, the toner bottle, including the first and second valve members, is engageable with a valve opening member that is slidably supported on the toner hopper. The tabs of the first and second valve members are received in a recess of the valve opening member. In a first exemplary embodiment of the toner loading system, toner bottle and toner hopper according to the invention, the valve opening member is a toner hopper adaptor that includes an annular projection including a slot having a groove extending from the slot. The tabs of the first and second valve members engage the slot. The tab of the second valve member is blocked from rotation by the slot while the tab of the first valve member may rotate in the groove. Rotating the toner bottle, and thus the first valve member, causes the apertures of the first valve member to overlap the apertures of the second valve member and allows toner to be dispensed from the toner bottle. The tab of the first valve member is held in the groove and prevents the bottle from being removed from the toner hopper adaptor during dispensing of the toner and thus prevents spillage of the toner.
In a second exemplary embodiment of the toner loading system, toner bottle and toner hopper according to the invention, the valve opening member is a toner hopper slider that includes a plurality of retaining stops on a bottom surface for engaging the tabs of the first and second valve members. A first retaining stop engages the tab of the second valve member to prevent rotation of the second valve member. A second retaining stop is offset circumferentially from the first retaining stop and engages the tab of the first valve member to stop rotation of the first valve member. When the first and second retaining stops engage the tabs of the first and second valve members, the apertures of the first and second valve members overlap and toner can be dispensed from the toner bottle. A release stop engages the tabs of the first and second valve members when the toner bottle is rotated to close the toner bottle valve. Thus, the release stops rotation of the first and second valve members relative to each other such that the apertures of the first and second valve members do not overlap and permits the toner bottle to be removed from the toner hopper slider.
In a third exemplary embodiment of the toner loading system, toner bottle and toner hopper according to the invention, a cap is provided over the second valve member. The cap aligns the first and second valve members during transit and storage of the toner bottle so that toner may not be dispensed from the toner bottle. The cap includes a lever that is connected to the first valve member. The connection between the first valve member and the lever may be broken by pivoting the lever. The cap may then be removed from the second valve member and the toner bottle may be engaged with the valve opening member to dispense the toner.
Various exemplary embodiments of the toner loading system, toner bottle and toner hopper according to this invention may be adapted for use with existing image forming apparatus that use toner to form images. Various exemplary embodiments of the toner loading systems according to the invention prevent spillage of the toner by sealing the toner bottle until the toner bottle is securely engaged with the valve opening member of the toner hopper and the toner bottle is rotated. Various exemplary embodiments of the toner loading systems according to this invention also prevent spillage by supporting the toner bottle while it is being translated to distribute the toner and preventing the toner bottle from disengaging the hopper while the valve is open.
Other features of the invention will become apparent as the following description proceeds and upon reference to the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to
FIG. 1
, in a first exemplary embodiment, a toner loading system according to the invention includes a toner bottle
100
that includes a plurality of projections
102
. Although not shown in
FIG. 1
, it should be appreciated that the toner bottle
100
can also include a number of projections
102
on the far side of the toner bottle. The projections
102
engage notches
122
of a first valve member
120
of a toner bottle valve
110
to secure the first valve member
120
non-rotatably over the opening
104
of the toner bottle
100
. The first valve member
120
has a pair of tabs
126
(only one of which is shown in
FIG. 1
) and an annular shelf
124
.
A second valve member
130
of the toner bottle valve
110
is rotatably secured in the first valve member
120
. The second valve member
130
may be snap fit into the first valve member
120
so that the second valve member
130
is rotatable relative to the first valve member
120
. The second valve member
130
may include an annular ridge on its outer circumference that mates with an annular groove on the inner circumference of the first valve member
120
, or vice versa. It should be appreciated that any known or later developed mating connection that allows the second valve member
130
to be secured to the first valve member
120
so that the second valve member
130
is rotatable relative to the first valve member
120
may be used.
The second valve member
130
includes a pair of tabs
132
(only one shown in
FIG. 1
) and a pair of apertures
136
. As shown in
FIG. 2
, apertures
128
in the first valve member
120
do not overlap the apertures
136
in the second valve member
130
when the tabs
132
of the second valve member
130
are aligned with the tabs
126
of the first valve member
120
. This orientation is shown in
FIGS. 2 and 4
. When the tabs
126
and
132
are aligned and the apertures
128
and
136
do not overlap, no toner may be dispensed from the toner bottle
100
. Although the first and second valve members
120
and
130
have been shown and described with two tabs each, it should be appreciated that any number of tabs may be used.
As shown in
FIG. 3
, the apertures
128
of the first valve member
120
are each less than 90° of the circumference of the first valve member
120
. The apertures
136
of the second valve member
130
are also less than 90° of the circumference of the second valve member
130
. This ensures that a complete seal is formed when the apertures
128
and
136
are not overlapping and the tabs
126
and
132
are aligned. Although the first and second valve members
120
and
130
have been shown with two apertures, it should be appreciated that the first and second valve members
120
and
130
may include any number of corresponding apertures with the angular extents of the apertures adjusted correspondingly to ensure that a complete seal is formed.
As shown in
FIGS. 1 and 2
, the second valve member
130
includes a surface member
134
in which the apertures
136
are formed. The surface member
134
may have a convex shape. As shown in
FIG. 3
, the first valve member
120
includes a flexible surface member
129
in which the apertures
128
are formed. The convex surface member
134
engages and stretches the flexible surface member
129
to ensure the seal between the first and second valve members
120
and
130
. It should be appreciated that the convex surface member may be provided on the first valve member instead of the second valve member and that the flexible surface member may be provided on the second valve member instead of the first valve member.
Referring again to
FIG. 1
, in the first exemplary embodiment of the toner loading system according to the invention, a toner hopper adaptor
210
is secured to an existing hopper slider
14
that is slidably supported on a toner hopper
10
of an image forming apparatus. The hopper slider
14
is slidable in the direction of arrow C on the toner hopper
10
. The toner hopper adaptor
210
may be snap fit to the hopper slider
14
so that the toner hopper adaptor
210
is slidable with the hopper slider
14
on the toner hopper
10
. It should be appreciated that the toner hopper adaptor
210
may be secured to the hopper slider
14
by any known or later developed mating connection that secures the toner hopper adaptor
210
to the hopper slider
14
and allows the toner hopper adaptor
210
to slide with the hopper slider
14
on the toner hopper
10
.
As shown in
FIG. 6
, the toner hopper adaptor
210
includes an annular projection
230
that fits within an aperture
12
of the hopper slider
14
. The annular projection
230
may include an annular ridge
236
that has a diameter slightly larger than the diameter of the aperture
12
of the hopper slider
14
. The annular ridge
236
is snap fit within the aperture
12
to secure the toner hopper adaptor
210
to the hopper slider
14
. It should be appreciated, however, that the toner hopper adaptor
210
may be secured to a non-sliding member or to an opening in the toner hopper
10
to allow filling of the toner hopper
10
.
Referring to
FIGS. 5 and 6
, the toner hopper adaptor
210
includes a number of recesses
220
equal to the number of tabs
126
/
132
. The tabs
126
and
132
of the first and second valve members
120
and
130
, respectively, fit into the recesses
220
when the tabs
126
and
132
are aligned. A like number of slots
232
are formed in the annular projection
230
at positions corresponding to the recesses
220
. A groove
234
extends from each slot
232
so that a total angular extent of the slot
232
and the groove
234
is approximately 90°, for embodiments that have two slots, or a corresponding angular extent for embodiments that have more than two slots.
Referring to
FIGS. 7 and 8
, the tabs
126
and
132
of the first and second valve members
120
and
130
, respectively, are aligned and the apertures
128
and
136
of the first and second valve members
120
and
130
, respectively, are not overlapping. Thus, toner cannot be dispensed from the toner bottle
100
. The toner bottle
100
is aligned with the toner hopper adaptor
210
so that the tabs
126
and
132
are aligned with the recesses
220
. As shown in
FIG. 8
, the toner bottle
100
is moved in the direction of arrow D until the toner bottle
100
is in the position shown in FIG.
9
. As shown in
FIG. 9
, the tabs
126
and
132
fit into the slot
232
of the annular projection
18
. The tab
132
of the second valve member
130
fits into the bottom of the slot
232
so that the second valve member
130
cannot rotate relative to the toner hopper adaptor
210
. The tab
126
of the first valve member
120
is aligned with the groove
234
extending from the slot
232
.
As shown in
FIG. 9
, the toner bottle
100
, and thus the first valve member
120
may be rotated in the direction of arrow A. As the first valve member
120
is rotated relative to the second valve member
130
, the apertures
128
begin to overlap the apertures
136
. The toner bottle
100
may be rotated until the tab
126
reaches the end of the groove
234
as shown in FIG.
10
. In this position, the tabs
126
and
132
are offset approximately 90° from each other and the apertures
128
completely overlap the apertures
136
. The toner can be dispensed from the toner bottle
100
. In this position, the toner bottle
100
may not be disengaged from the toner hopper
10
as the tab
126
of the first valve member
120
is engaged in the groove
234
of the toner hopper adaptor
210
, thus preventing possible spilling of the toner.
As shown in
FIGS. 1 and 7
, the annular shelf
124
of the first valve member
120
has a larger diameter than the annular projection
230
of the toner hopper adaptor
210
and a larger diameter than the aperture
12
of the hopper slider
14
. When the first and second valve members
120
and
130
are inserted into the toner hopper adaptor
210
, the annular shelf
124
engages the top of the toner hopper adaptor
210
and supports the toner bottle
100
. The operator can safely release the toner bottle
100
without the toner bottle
100
tipping over and disengaging from the toner hopper adaptor
210
.
After the toner bottle
100
is engaged with the toner hopper adaptor
210
and rotated to open the toner bottle valve
110
, as shown in
FIGS. 9 and 10
, the toner bottle
100
is translated back and forth along the toner hopper
10
by sliding the hopper slider
14
in the direction of arrow C as shown in
FIG. 1
to evenly distribute the toner in the toner hopper
10
. A label or other indicia may instruct the operator to translate the toner bottle
100
back and forth. The toner bottle
100
cannot disengage from the toner hopper adaptor
210
as the tab
126
of the first valve member
120
is firmly held in the groove
234
, as shown in FIG.
10
. The annular shelf
124
of the first valve member
120
also supports the toner bottle
100
and prevents the toner bottle
100
from tipping over during translation of the toner bottle
100
back and forth on the toner hopper
10
.
Referring again to
FIGS. 9 and 10
, to release the toner bottle
100
from the toner hopper adaptor
210
, the toner bottle
100
is rotated in the direction of arrow B until the tabs
126
and
132
are aligned as shown in FIG.
9
. Once the tabs
126
and
132
are aligned, the apertures
128
and
136
of the first and second valve members
120
and
130
, respectively, no longer overlap and no toner may be dispensed. The toner bottle
100
may be disengaged from the toner hopper adaptor
210
without spilling toner.
Referring to
FIGS. 11-14
, in a second exemplary embodiment of the toner loading system according to the invention, a toner bottle valve
310
includes a first valve member
320
mounted on a toner bottle
300
. The first valve member
320
includes a reduced diameter portion
323
that is smaller in diameter than the diameter of the opening
304
of the toner bottle
300
. The reduced diameter portion
323
is press fit into the opening of the toner bottle
300
so that the first valve member
320
is non-rotatably secured to the toner bottle
300
. The first valve member
320
includes an annular shelf
324
and tabs
326
, only one of which is shown in FIG.
11
.
A second valve member
330
is rotatably secured in the first valve member
320
in a manner similar to the first and second valve members
120
and
130
of the first exemplary embodiment. The second valve member
330
includes apertures
336
and tabs
332
, only one tab
332
being shown in FIG.
11
. As shown in
FIG. 14
, the apertures
336
of the second valve member
330
do not overlap apertures
328
in the first valve member
320
when the tabs
326
are aligned with the tabs
332
. As in the first exemplary embodiment, the apertures
328
of the first valve member
320
and the apertures
336
of the second valve member
330
extend for less than 90° of the circumference of the first and second valve members
320
and
330
, respectively. Although two apertures
328
and
336
are shown for each of the first and second valve members
320
and
330
, respectively, it should be appreciated that the corresponding number of apertures in the first and second valve members
320
and
330
may include any number of corresponding apertures with the angular extent of the apertures adjusted correspondingly to ensure that a complete seal is formed.
The second exemplary embodiment of the toner loading system includes a hopper slider
400
that is secured to the hopper
10
and that is slidably supported by the toner hopper
10
. The hopper slider
400
may replace existing hopper sliders used on existing toner hoppers installed on existing image forming apparatus or the hopper slider
400
may be originally installed in new or existing image forming apparatus. Referring to
FIG. 11
, the hopper slider
400
is generally planar and has an aperture
410
that includes a number of recesses
412
. The recesses
412
accept the tabs
326
and
332
when the tabs
326
and
332
are aligned and the toner bottle
300
is sealed. As shown in
FIG. 12
, the bottom of the hopper slider
400
includes first retaining stops
422
, second retaining stops
424
and release stops
426
.
To dispense toner, the toner bottle
300
is moved toward the hopper slider
400
and the tabs
326
and
332
pass through the recesses
412
. The diameter of the annular shelf
324
is larger than the diameter of the aperture
410
and prevents the first valve member
320
from passing entirely through the aperture
410
. The annular shelf
324
also supports the toner bottle
300
on the hopper slider
400
and prevents the toner bottle
300
from tilting when the hopper slider
400
and the toner bottle
300
are translated back and forth to evenly distribute the toner in the toner hopper
10
.
Once the annular shelf
324
is engaged with the top of the hopper slider
400
, the operator can rotate the toner bottle
300
. The toner bottle
300
is rotated and the tabs
332
of the second valve member
330
engage the first retaining stops
422
. The second valve member
330
is prevented from rotating any further by engaging the tabs
332
with the first retaining stops
422
. The toner bottle
300
and the first valve member
320
may be further rotated until the tabs
326
of the first valve member
320
engage the second retaining stops
424
. When the tabs
326
and
332
are not aligned, the apertures
328
of the first valve member
320
overlap the apertures
336
of the second valve member
330
and toner may be dispensed.
The toner slider
400
may be translated back and forth on the toner hopper
10
to evenly distribute the toner. Once the toner hopper
10
is replenished, the toner bottle
300
is rotated in the opposite direction until the tabs
326
and
332
are realigned. Once the tabs
326
and
332
are realigned, the apertures
328
and
336
of the first and second valve members
320
and
330
no longer overlap and the toner bottle
300
is sealed. The release stops
426
engage the tabs
326
and
332
and prevent the toner bottle
300
from being rotated past the recesses
412
and keep the tabs
326
and
332
aligned with the recesses
412
. The toner bottle
300
may then be removed from the hopper slider
400
without spilling the toner.
Referring to
FIGS. 11-14
, an axial distance L between the annular shelf
324
and the tabs
326
of the first valve member
320
may be approximately equal to the thickness W of the hopper slider
400
. This arrangement ensures a proper fit between the first valve member
320
and the hopper slider
400
and prevents the first valve member
320
from tilting or pivoting when engaged with the hopper slider
400
. A radial width R of the tabs
326
may be equal to twice the thickness W of the hopper slider
400
.
As in the first exemplary embodiment, a surface member
334
may have a convex shape. As shown in
FIG. 11
, the apertures
336
may be formed in the surface member
334
