Abstract
A leaflet dispensing apparatus having a main structural body on which is mounted a carousel including a plurality of magazine for storing leaflets and an intermediate chute for transferring the leaflets from the carousel to a dispensing wheel. The dispensing wheel is adapted to remove a leaflet from the intermediate chute and to transport the leaflet to a dispensing area where a dispensing blade pushes the leaflet onto or into a container being transported by a conveyor located adjacent to the leaflet dispensing apparatus. The magazines for storing leaflets are the vehicle for reloading the carousel. The magazines may be discarded after use or may be re-used.
Description
FIELD OF THE INVENTION
The invention relates in general to an apparatus for positioning leaflets on containers or inserting leaflets inside containers in a production environment. The invention finds applications mainly in the pharmaceutical industry where comprehensive information about the product may be included in each container sold in the market. The apparatus is positioned next to a conveyor system on which containers are transported and then adjusted to either affix leaflets to the outer part of the containers or insert leaflets inside the containers. The apparatus allows easy refilling of leaflets and can be rapidly adapted to dispense leaflets of different sizes.
BACKGROUND OF THE INVENTION
Many consumer products, especially pharmaceutical products are required to provide information about the product and/or instructions on the use of the product with each package sold on the market. Square folded leaflets is the most common format for providing that information to the consumer and these may come in a variety of sizes. Leaflets are either inserted into the package or affixed to an outer portion of the package. Many machines have been developed to insert leaflets into containers by means of endless belts with clips which effectively carry and hold the leaflet until it is dumped into the container. Machines designed to affix leaflets to the outer part of a container are not as common and one must look at labeling machines to find devices that produce a similar result. However, labels are usually made of more resilient material than leaflets, are not folded, and one side is often coated with a strong glue. These machines are often complex and require that the container be held firmly when the label is applied to the outer part of the container. Machines designed to both insert leaflets into containers or affix leaflets to the outer part of containers are practically non-existing.
In all machines of the prior art, the mechanisms for feeding leaflets or labels to the dispensing area are unreliable and cumbersome and problems arise during operation. Leaflets may get misaligned or get caught and the production must be stopped to rearrange the stored leaflets. Leaflets are often stored and fed through a cartridge that features spring loaded elements to push the row of leaflets to the dispensing area. Once the cartridge is emptied, it must be replaced and reloaded and this operation may require that the machine be stopped.
Considering the wide application, especially in the pharmaceutical industry, of this type of apparatus, there is a demand for an leaflet dispensing apparatus better adapted to position leaflets either on a container or inside a container, that is compact, easy to operate and reliable.
OBJECTS AND STATEMENT OF THE INVENTION
It is thus an object of the invention to provide a leaflet dispensing apparatus specifically adapted to be reloaded with new leaflets in a manner that is quick, simple and reliable.
It is another object of the invention to provide a leaflet dispensing apparatus that can affix leaflets to a plurality of position on a container and that can insert a leaflet inside a container.
It is another object of the invention to provide a simple mechanism for removing leaflets from a stored position and to transport leaflets to the dispensing area.
It is another object of the invention to provide magazines for packing leaflets and for use as pre-loaded cartridge for the production environment.
As embodied and broadly described herein, the invention provides a leaflet dispensing apparatus comprising:
a main structural body;
a carousel rotatably mounted to said main structural body, said carousel including a plurality of magazines adapted to hold leaflets, each of said magazine having at least one open extremity through which said leaflets may enter or exit, said magazines being disposed in an upright position wherein said at least one open extremity opens downwardly;
a retaining plate positioned below said magazines and adapted to close said at least one open extremity, said retaining plate including an orifice in communicative relation with an intermediate chute;
a dispensing wheel rotatably mounted to said main structural body having an angled peripheral side, said peripheral side including at least one pocket adapted to remove and transport said leaflets, said dispensing wheel in communicative relation with said intermediate chute; and
a dispensing blade adapted to move a leaflet carried by said dispensing wheel towards a container.
As embodied and broadly described herein, the invention also provides a leaflet dispensing apparatus adapted to deposit pieces of folded printed matter into or onto small containers in a production line; said apparatus including a support, a main structural body and a revolvable carousel, said carousel being, in operation, adapted to transport a plurality of vertically disposed cartridges; said cartridges being adapted to be filled with said pieces of folded printed matter and to dispense the same by gravity into an intermediate chute; said apparatus further comprising a rotatable dispensing wheel; said dispensing wheel including a plurality of vacuum-actuated pockets about its periphery; each of said pockets being adapted in operation to receive one of said pieces of folded printed matter from said chute; said dispensing wheel being positioned on said apparatus such that each of said pockets is adapted to align one at a time with an exit port of said intermediate chute during rotation of said dispensing wheel; the periphery of said wheel being positioned adjacent a container conveyor and a removal knife such that, in operation, as each of said pockets approaches said conveyor said knife removes said pieces of folded printed matter and deposits it into or onto a container.
In a preferred embodiment of the invention, the leaflet dispensing apparatus comprises a main structural body on which a carousel, featuring a plurality of magazines each containing a predetermined quantity of leaflets, is mounted. The carousel is in communicative relation with an intermediate chute which enables the transfer of leaflets from a magazine of the carousel to a dispensing wheel located immediately below the intermediate chute. The dispensing wheel is a rotatable disc adapted, in operation, to remove a leaflet from the intermediate chute, to transfer and deliver the leaflet to an oncoming container transported on a conveyor belt. The dispensing wheel features a plurality of pockets each having a small vacuum chamber that creates the necessary suction to remove a leaflet from the intermediate chute and to hold the leaflet during transport to the container traveling on the conveyor belt. To assist in the positioning of the leaflet onto or into the container, a dispensing blade is preferably provided to push the leaflet at the opportune time i.e. when the leaflet is located next to the container. Glue may be applied to the leaflet as the leaflet is being transported by the dispensing wheel or it may be applied to the container itself upstream from the apparatus.
The carousel ensures a steady flow of properly oriented leaflets to the intermediate chute by storing the leaflets in magazines designed specifically to the effect. The carousel is constructed with a central star-wheel in which a plurality of magazines containing leaflets are placed in the upright position at regular intervals. In operation, one magazine is aligned with the intermediate chute in order to transfer its content of leaflets to the intermediate chute. Once a magazine is empty, the carousel rotates in a step-like manner to position the next full magazine in alignment with the intermediate chute. The intermediate chute acts as a buffer zone or reserve from the moment a magazine is empty to the moment a full magazine is brought in alignment with it. Once all the magazines of a carousel are empty, the entire carousel can be replaced quickly and easily with a new carousel carrying full magazines.
Other objects and features of the invention will become apparent by reference to the following description and the drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
With reference to
FIG. 1
of the annexed drawings, the present invention provides a novel leaflet dispensing apparatus designated by the reference numeral
20
. The apparatus
20
is constructed of a supporting structure
21
featuring adjustable legs
23
provided to adjust the height of the apparatus, a main structural body
22
and a carousel
30
rotatably mounted to the main structural body
22
in which is stored leaflets
25
to be dispensed. The main structural body
22
is constructed with an angular section
24
to which is mounted a rotatable dispensing wheel
50
adapted to retrieve leaflets
25
from carousel
30
and, to transport and deliver the leaflets
25
, one by one, to a container
26
traveling on a conveyor system
27
and guided and supported by a guide rail
28
.
FIGS. 3 and 4
focus on the dispensing wheel
50
and its elements and ancillaries. The dispensing wheel
50
is a disc of sufficient thickness to provide support to a leaflet
25
. The periphery
52
of the dispensing wheel
50
is angled and it features a plurality of pockets
54
, each having a smoothly angled entry surface
55
and a sharply angled retaining edge
56
. Inside each pockets
54
, is a small vacuum chamber
57
located on the entry surface
55
. The purpose of chamber
57
is to create a suction of sufficient force to remove a leaflet
25
from an intermediate chute
32
and hold the leaflet
25
as the dispensing wheel
50
rotates and transports the leaflet
25
towards the conveyor system
27
.
A dispensing blade
60
is provided to cooperate with the dispensing wheel
50
to position leaflets
25
onto containers
26
or inserting leaflets
25
into containers
26
. The dispensing blade
60
is preferably activated with a pneumatic actuator
62
(shown in FIG.
5
and FIG.
6
). At the opportune time, the dispensing blade
60
moves towards a container
26
passing on the conveyor
27
and in the process, pushes a leaflet
25
held in a pocket
54
onto the top or the side of container
26
or into container
26
. There are two types of dispensing blades
60
which are of similar design. The first type has an extended upper flange to push the leaflet onto the cap of container
26
or into the container
26
while the second type has an extended lower flange instead, to push the leaflet onto the side of container
26
.
Now referring to
FIGS. 5 and 6
, it can be seen that the periphery
52
of the dispensing wheel
50
is angled in such a way as to enable the removal of a leaflet
25
from the substantially vertical intermediate chute
32
and the delivery of the same leaflet
25
onto a container
26
. In a preferred embodiment, the periphery
52
of the dispensing wheel
50
is angled at 45 degrees in relation to the axis of rotation of the dispensing wheel
50
. In this arrangement, the periphery
52
of the dispensing wheel
50
is substantially parallel to the leaflet
25
held in the intermediate chute
32
and it is also substantially parallel to the side portion of container
26
transported by the conveyor
27
.
Referring to
FIG. 6
, the dispensing wheel
50
is mounted at its center to the central column
76
of the vacuum rotary connector
70
. A motor
101
linked to the central column
76
through a shaft
56
imparts rotary motion to the central column
76
. The central column
76
is supported at one end by its connection to the motor
101
and at its other end, by a central bearing
75
. The vacuum rotary connector
70
is mounted to the angular section
24
of the main structural body
22
. The axis of the vacuum rotary connector
70
is oriented at an angle consistent with the angle of the periphery
52
of the dispensing wheel
50
. In a preferred embodiment, the vacuum rotary connector
70
is mounted to the angular section
24
at an angle of 45 degrees from the vertical.
The vacuum rotary connector
70
effectively imparts rotary motion to the dispensing wheel
50
and it also distributes vacuum pressure to the various chambers
57
of the dispensing wheel
50
by connecting a vacuum source to the various chambers
57
through vacuum lines. The vacuum chambers
57
previously described in
FIGS. 3 and 4
are connected to vacuum lines
71
drilled into the dispensing wheel
50
. The vacuum lines
71
communicate with the central column
76
through vacuum lines
72
located underneath the dispensing wheel
50
. The central column
76
features vacuum lines
73
drilled through its center. Each vacuum line
73
is itself linked to a vacuum source (not shown) by the ports
74
of the body
77
of the vacuum rotary connector
70
. Each of the vacuum lines
73
is connected with one port
74
via a groove at their mating point so that the vacuum connection is maintained for a predetermined segment of the total rotation of the rotating column
76
. This vacuum connection arrangement enables the vacuum pressure to be turned on or turned off in the various vacuum chambers
57
of the pockets
54
as a function of the geometrical position of the individual pockets
54
.
Leaflets
25
to be dispensed are stacked up in individual magazines
40
which are held in the upright position in the carousel
30
by a central star-wheel
34
. The carousel
30
is rotatably mounted at the central star-wheel
34
on a central post
38
and secured to the central post
38
with only one large handle screw
35
for easy installation and removal. The central star-wheel
34
and the central post
38
have a positioning mechanism (not shown) to insure that when the central star-wheel
34
is installed on the central post
38
, it is in the proper radial orientation. The central post
38
is connected to a motor and gearbox
39
(as shown in
FIG. 5
) which imparts rotary motion to the carousel
30
in a step-like or indexed manner.
FIG. 7
illustrates a typical carousel viewed from above showing the radial positioning of each magazine
40
. The rotary motion of the central post
38
is indexed into as many segments as there are magazines
40
in carousel
30
. In the illustrated example, there are sixteen magazines
40
; therefore the rotation of the central post
38
will be divided into sixteen equal segments of 22.5 degrees each. The number of magazines
40
stored in a carousel is not restricted to the illustrated example and can be any number. The rotary motion of the central post
38
simply has to be indexed in relation to the radial distance between two magazines
40
held in the carousel
30
.
As a variant of the carousel
30
, FIG.
7
a
illustrates the magazines
40
mounted on a conveyor system
88
. This arrangement permits the loading of more magazines
40
and therefore, more leaflets
25
into the apparatus. Empty magazines
40
may be replaced individually at a point downstream from the dispensing area or the entire conveyor system
88
may be replaced with a new one with full magazines
40
. The conveyor system
88
operates essentially the same way as the carousel
30
wherein each magazine
40
is positioned in alignment with the intermediate chute
32
into which it unloads its leaflets
25
. The displacement of the conveyor system
88
to replace an empty magazine
40
is also indexed in relation to the distance separating two magazines
40
held in the conveyor system
88
.
FIG. 8
is an exploded view of the main components of the carousel
30
showing at the bottom section of the carousel
30
, a retaining plate
36
comprising an orifice
37
which opens onto the intermediate chute
32
located immediately below the retaining plate
36
. The purpose of the retaining plate
36
is to partially support the magazines
40
and specifically to prevent leaflets
25
from escaping through the open end
48
of the magazines
40
. The retaining plate
36
is oriented with its orifice
37
lined up with the intermediate chute
32
and does not rotate with the carousel
30
. The upper surface of the retaining plate
36
is smooth to allow easy motion as the bottom leaflet
35
of every magazine
40
slides on this upper surface as the carousel
30
rotates.
Each magazine
40
is mounted to an aperture
42
of the star-wheel
34
with the agency of an adapter
41
. The magazine
40
is positioned into the adapter
41
and held within by the mating of spring loaded dowels
43
with the grooved openings
44
located on each side of the magazines
40
. The adapter
41
is mounted to the aperture
42
of the star-wheel
34
and locked into position by inserting a fastener
45
through the adapter
41
and into a hole
46
located behind each aperture
42
.
The adapter
41
is provided so that the star-wheel
34
may accommodate a variety of magazines
40
of different sizes. The size of the magazine
40
essentially depends on the sizes of the leaflets
25
.
The intermediate chute
32
is mounted to a support plate
33
on which the retaining plate
36
is seated. The intermediate chute
32
comes in a variety of sizes to accommodate leaflets
25
of different sizes; it can removed and replaced by an intermediate chute
32
of different size as need be. The purpose of the intermediate chute
32
is to create a buffer zone or a reserve of leaflets
25
so that when a magazine
40
is empty and the carousel rotates to bring a full magazine in line with the orifice
37
of the retaining plate
36
, there are still leaflets available to the dispensing wheel
50
. This arrangement prevents the flow of containers
26
from being stopped. The intermediate chute
32
, as the magazines
40
, is dimensioned to closely fit a particular size of leaflet
25
to insure that the leaflets are properly guided and do not become misaligned. The intermediate chute
32
features, at its bottom end
90
, edges
92
adapted to hold the sides of a leaflet while leaving the central portion of the leaflet exposed to the dispensing wheel
50
. As can be seen in
FIG. 8
, the periphery
52
of the dispensing wheel
50
is located directly between the edges
92
of the intermediate chute
32
. The dispensing wheel
50
is therefore able to remove the exposed leaflet
25
when a pocket
54
passes by the intermediate chute
32
with the suction created by the vacuum chamber
57
.
In operation, one magazine
40
of the carousel
30
is lined up with the orifice
37
leading to the intermediate chute
32
. Leaflets
25
travel down by gravity into the intermediate chute
32
. Once a magazine
40
has unloaded all its leaflets
25
, the carousel
30
is rotated so as to bring into alignment with the orifice
37
, the next full magazine
40
. Once all the magazines
40
of the carousel
30
are empty, the empty carousel
30
is removed by simply undoing the large screw handle
35
(as shown in FIG.
6
). A new carousel
30
with full magazines
40
is then installed and the screw handle
35
re-fastened.
Referring to FIGS.
9
and
9
a
, the magazines
40
are receptacles or cases adapted to hold leaflets to be dispensed. Magazines
40
Magazines
40
are tailor-made to fit different size of leaflets
25
. The interior of the magazines
40
is dimensioned to closely fit a particular size of leaflet
25
so that the leaflets
25
are unable to rotate or become misaligned and therefore in the ideal orientation for dispensing. The magazines
40
are long, thin rectangular receptacles with one extremity
48
opened and have narrow grooved openings
44
on two opposite sides of the magazine
40
which are provided to secure the magazine
40
in a certain position into the adapter
41
. The magazines
40
also features a long narrow aperture
47
extending substantially the length of the magazine
40
through which the amount of leaflets left in the magazine
40
can be verified. Leaflets
25
are inserted in the magazine
40
through the open extremity
48
and oriented so that when the magazine
40
stands upright, the leaflets
25
are stacked up. The magazine
40
is positioned into the adapter
41
and held within the adapter
41
by the mating of spring loaded dowels
43
with the grooved openings
44
located on each side of the magazines
40
as shown in FIG.
9
a.
It can be seen that a small gap exist between the lower spring loaded dowels
43
and the bottom of the narrow grooved openings
44
which permits some minor movements of the magazine
40
. The magazines
40
are installed in the carousel
30
with the open extremity
48
facing down. In operation, the stacked leaflets
25
are discharged through the open extremity
48
into orifice
37
of the retaining plate
36
and into the intermediate chute
32
. Magazines
40
can be produced out of inexpensive molded material which can be simply discarded after use. Magazines
40
can also be produced out of a more rigid molded material permitting the recycling of magazines
40
by returning them to the leaflets manufacturer for reloading. Magazines
40
can also be of a more permanent type for the purpose of on-site reloading. The magazine
40
is removed from carousel
30
, refilled with new leaflets and reinstalled in the carousel
30
.
FIGS. 10
to
13
illustrate the dispensing wheel
50
and dispensing blade
60
in operation from two points of view and at two different moments. In
FIGS. 10 and 11
, the dispensing wheel
50
is shown in a counterclockwise rotation, the dispensing blade
60
is retracted, a pocket
54
of the dispensing wheel
50
is about to pick up a leaflet
25
from the intermediate chute
32
, a second pocket
54
is carrying a leaflet
25
toward the containers
26
, a third pocket
54
is about to release a leaflet
25
onto a container
26
and a fourth pocket
54
is empty after having released a leaflet
25
.
FIGS. 12 and 13
illustrate the leaflet dispensing apparatus
20
one instant later. In
FIG. 13
, the pocket
54
located at the 12 o'clock position pulls a leaflet
25
from the intermediate chute
32
with the suction force created by the vacuum chambers
57
inside the pocket
54
. At the 9 o'clock position, a glue dispensing device may be installed (not shown) to apply a thin layer of glue to the leaflet
25
held and carried by the dispensing wheel
50
as it passes by that position. At the 6 o'clock position, the vacuum rotary connector
70
shuts the vacuum pressure of the particular pocket
54
at the same moment the dispensing blade
60
extends and pushes the leaflet
25
onto the passing container
26
. During the leaflet dispensing sequence, the container
26
is held in place, from the opposite end, by the guide rail
28
which prevents the container
26
from falling off the conveyor belt
27
. The dispensing blade
60
applies a small pressure to the leaflet
25
to ensure that the glue applied previously on the leaflet
25
adheres firmly to the container
26
.
FIG. 14
illustrates the variant in which the leaflet
25
is positioned and affixed to the top portion of the container
26
. It can be seen that the dispensing blade
60
used for this purpose has a longer upper flange that the model used for positioning leaflets
25
to the side of the containers
26
. Either type of dispensing blade
60
may be used when leaflets
25
are to be inserted into the container
26
. When inserting leaflets
25
, the containers
26
are transported on the conveyor belt
27
without their lids so that when a leaflet
25
is pushed by the dispensing blade
60
, the leaflet
25
falls into the container
26
.
