Radio frequency labels on reusable containers
Abstract
It is possible to accurately and conveniently determine the
origin, contents, position, and/or destination of a reusable
container (such as a tote or bin, particularly for a manufacturing
process) by applying a permanent adhesive label with embedded
programmable RFID to the reusable container at a location where the
RFID may be detected and reprogrammed. The RFID is programmed with
accurate variable information including relating to at least one of
the origin, contents, position, and destination of the container,
and at at least one location the variable information of the RFID
is detected. After a first use of the reusable container it is
reprogrammed with other accurate variable information, and the
detecting and reprogramming are repeated multiple times. Preferably
the label is of a substantially moisture impermeable material such
as a plastic film, or synthetic paper.

Description
BACKGROUND AND SUMMARY OF THE INVENTION
[0001] In many systems and processes, such as in industrial and
manufacturing processes, reusable containers are used to transport
raw materials or finished goods or objects from an origin station
to others, and in order for the personnel running the process to be
able to track and effectively utilize such reusable containers some
sort of a labeling system is provided. A label typically provides
information such as the origin and destination of the container,
its contents, its particular position at a point in time, and a
wide variety of things such as batch numbers, parts numbers, serial
numbers, volume or quantity, etc.
[0002] Conventional labeling is typically done using some sort of a
paper labeling system. For example, such as shown in U.S. Pat. No.
5,628,858, and the prior art discussed therein, a placard or
envelope is provided which contains a discardable label which can
have bar code or other information imaged therein, and which is
removed and discarded once the container has been used for one
particular use (for example transporting materials or objects from
an origin point to a destination point). While such systems can be
effective under many circumstances, there is the possibility that
the integrity of the label will be compromised, or that it can be
detached from the container, and also a fair of amount of waste is
involved in constantly discarding labels.
[0003] According to the present invention a method of accurately
determining the contents, position and/or designation of a reusable
container, and such a reusable container per se, are provided. The
invention is particularly suitable with respect to bins, totes, or
other open top containers, but may be utilized with any type of
reusable container whether open or closed. Also, the invention may
be utilized with any suitable process for manufacturing or
otherwise treating objects, goods, materials, products, or the
like.
[0004] According to one aspect of the present invention there is
provided a method of accurately determining at least one of the
contents, position, and destination of a reusable container
comprising: (a) Applying a permanent adhesive label with imbedded
or mounted programmable RFID device to the reusable container at a
location where the RFID device may be detected and reprogrammed.
(b) Programming the RFID device with accurate variable information
including relating to at least one of the origin, contents,
position, and destination of the reusable container. (c) At at
least one location, detecting the programmed variable information
of the RFID device. (d) After a first use of the reusable container
pursuant to the programmed variable RFID information thereof,
reprogramming the RFID device with other accurate variable
information including relating to at least one of the origin,
contents, position, and destination of the reusable container. And
(e) repeating (c) and (d) multiple times.
[0005] In the practice of the method typically (b) is also
practiced to program the RFID device with non-variable information
which is not affected by subsequent reprogramming pursuant to (d)
and (e). Preferably (a) is practiced by using a substantially
moisture impermeable label, and including a label with human
readable indicia thereon visible from the exterior of the reusable
container. Typically (a) is practiced by applying a label to the
exterior of the reusable container (such as a flat surface
thereof), although if the RFID device can be properly detected the
label may be applied anywhere on the removable container.
[0006] According to one embodiment of the invention (a) practiced
using a label made by combining an RFID chip with a face
stock/transfer tape laminate, and verifying the functions of the
RFID device at least twice prior to final label construction.
According to another aspect of the invention (a) may be practiced
using paper stock mounting an RFID chip laminated between two
pieces of plastic film, one piece of plastic film having permanent
adhesive on an exterior surface thereof. According to yet another
embodiment (a) may be practiced using a plastic film stock having
properties simulating those of paper with an RFID chip embedded
therein.
[0007] Typically (b) (d), and (e) are practiced to program the RFID
device with at least two of or all of the origin, contents,
position, and destination of the reusable container, and the RFID
device may be programmed to including other information also
depending upon the material or objects or the like transported by
the reusable container. Also, for example, the reusable container
includes material or objects therein during passage thereof from a
programming position to a destination position; and wherein (b)-(e)
are practiced during a manufacturing process using or making the
material or objects.
[0008] According to another aspect of the present invention a
reusable container (such as a tote, bin, or the like) is provided
comprising the following components: A container body adapted to
hold therein material or objects being handled. A label having
pressure sensitive permanent adhesive and an RFID programmable chip
mounted thereon or embedded therein. And a label adhered to the
reusable container by pressure sensitive adhesive.
[0009] The label is preferably of substantially moisture impervious
material, and includes human readable indicia thereon. The label
may be applied to the exterior of the reusable container, which may
be one having an open top and containing material or objects
therein that are inserted and removed through the open top. Also,
the RFID chip is typically programmed by erasable variable
information including at least one of (preferably all of, as well
as possibly other information) the origin, contents, destination,
and position thereof, and non-variable information.
[0010] It is a primary object of the present invention to provide
an advantageous method of labeling a reusable container, and a
reusable container per se. This and other objects of the invention
will become clear from an inspection of a detailed description of
the invention and from the appended claims.

DETAILED DESCRIPTION OF THE DRAWINGS
[0018] FIG. 1 diagrammatically illustrates one exemplary form of a
method of accurately determining at least one of the origin,
contents, position, and destination of a reusable container,
according to the present invention. As indicated by block 10 in
FIG. 1, a permanent adhesive label with programmable RFID device
embedded therein or attached thereto is produced in a suitable
conventional manner. As indicated by box 11, the permanent label is
applied to a reusable container, such as a bin, tote, or the like.
Virtually any container may be utilized, for example, for
containers typically used to transport material or objects in
manufacturing or related processes. While such containers typically
have open tops, any type of reusable container (including closed
containers, those having particular seals, or the like) may be
utilized depending upon the particular process or system used.
Substantially simultaneously with, just before, or after the label
is applied to the reusable container, as indicated by box 12 the
RFID device of the label is programmed utilizing conventional
techniques, by accessing the RF inlet. The information that will be
programmed in the RFID device includes at least one of the
contents, position, and destination of a reusable container, and
preferably comprises all of this information, as well as any other
information that is suitable for that particular process, such as a
serial number, part number, etc.
[0019] At one or more locations during the passage of the bin from
its origin to its destination, as indicated by box 13 in FIG. 1,
the RFID device mounted to the bin by the label is detected,
utilizing any conventional detectors for that purpose. The
detectors may be positioned on or adjacent to a track over which
the reusable container moves, in association with a conveyor for
conveying the container, or in any other suitable location as long
as it is capable of detecting the RFID device and reading the
relevant information for that location that is programmed into the
RFID device. Any suitable existing detecting equipment that is
capable of performing this function may be utilized.
[0020] After a first use of the reusable container, such as when it
has reached its destination point and is to be recycled back to the
origin (or moved from a new origin to a new destination), as
indicated schematically by box 14 in FIG. 1 the RFID device is
reprogrammed with new variable information. As indicated at 15 in
FIG. 1, that new information is detected at one or more other
locations as indicated by 15 in FIG. 1, and the reprogramming and
detecting stages 14, 15 are repeated as desired, as indicated by
box 16 in FIG. 1, for the life of the container and/or RFID device
in the label.
[0021] The label manufacture stage 10 of FIG. 1 may be accomplished
in a wide variety of manners. For example, as illustrated in FIG. 2
of the drawings, label face stock, such as of a moisture
impermeable material such as TESLIN man-made paper-like material
that is printable and water resistant, TYVEK, polyester or other
plastic film stock that is printable, or the like, is unwound from
a roll 20 and has indicia imaged on the top face thereof utilizing
the conventional imaging/printing equipment 21 of any suitable type
(such as impact or non-impact, flexographic, ink jet, or the like
printers depending upon the substrate being imaged) and then that
imaged face stock is laminated--as indicated at station 22 in FIG.
2, utilizing conventional laminating equipment--to transfer tape 23
being unwound from a roll 24, with the release liner 25 of the
transfer tape 23 being taken up by roll 26. The printed laminate is
then rewound to form the roll 27.
[0022] After the procedure in FIG. 2, as seen in FIG. 3, the
printed laminate roll 27 is unwound so that the print face 28
thereof (see the face 28 in FIG. 2 also) is opposite the side where
an RFID device is to be applied to/embedded in the final label to
be produced, and the liner 29 covering the permanent pressure
sensitive adhesive 30 of the printed laminate is removed utilizing
roll 31.
[0023] To apply the RFID device, such as RFID inlets, in web
configuration as illustrated schematically at 32 in FIG. 3, first
the scanning procedure is practiced utilizing conventional scanning
equipment illustrated schematically at 33 and 33a in FIG. 3 in
order to register the RFID device to the print on the label face
stock, and also an RFID read/write device 34 is provided to verify
the functions of the programmable chip of the RFID device, and even
possibly program it at least with non-variable information, and
perhaps even some or all of desired variable information for the
first utilization of the label containing the RFID device depending
upon the particular process involved. Then the RFID device is cut
from the web to which it is attached utilizing any suitable
conventional cutting equipment such as illustrated schematically at
35 in FIG. 3 (such as a cutting cylinder having 180.degree. out of
phase blades cooperating with an anvil cylinder), and the RFID
device is placed on the adhesive 30 of the printed laminate. Then
where the labels are lined labels, a release liner 36 is laminated
over the adhesive in the RFID device utilizing conventional
equipment 37, labels are die cut from the substrate utilizing the
conventional die cutting equipment illustrated schematically at 38
in FIG. 3, and the cutoff matrix may be removed as illustrated
schematically at 39 in FIG. 3. The final web of labels then
preferably passes past a final RFID read verification station 40,
and the finished RFID device labels are wound onto a roll 41 which
is transported to a location where the labels are to be
utilized.
[0024] FIGS. 4 and 5 schematically illustrate a label 43 according
to the present invention from the roll 41 after removal of the
release liner thereof, in FIG. 5 showing the RFID device 44 greatly
enlarged in thickness for clarity of illustration. The label has
indicia 45 thereon that is human readable, on the face 28, and may
also have machine readable indicia such as bar codes or the like if
desired. The adhesive 30 on the face of the label 43 opposite the
face 28 is shown schematically in FIG. 5, and it is permanent
adhesive that when applied to a surface will essentially
permanently be fixed thereto. That is the adhesive will not
normally be detachable from the surface to which it is applied
without taking very special steps to remove it, and/or requiring
destruction of the label 43 to do so.
[0025] FIG. 6 schematically illustrates, generally by reference
numeral 48, an exemplary reusable container according to the
present invention, in this case in the form of a tote or bin. It is
to be understood that the illustration in FIG. 6 is schematically
and exemplary only, and that there are virtually an infinite
variety of different types of totes, bins, or like reusable
containers, both open topped (see the open top 49 for the bin 48 in
FIG. 6) or closed containers. For the particular embodiment
illustrated in FIG. 6, objects or materials may be placed in the
bin 48 through the open top 49 thereof and transported by the bin
48 by conveyors, tracks, carts, or any other suitable type
equipment, from an origin position past a number of different
positions to an ultimate destination.
[0026] According to the present invention a label 43 is shown
applied to the bin 48. In this preferred embodiment the label 43 is
applied to an exterior substantially flat surface of the bin 48
with the permanent adhesive 30 permanently adhering the label 43,
with embedded or attached RFID device 44, to the bin 48, and with
the indicia 45 being readable from the exterior of the container 48
by a human operator. While an exterior location is typically the
most convenient for the label 43, as long as the detecting
equipment utilized associated with the RFID device is suitable, and
as long easy human readability of the label indicia is not
necessary, the label 43 may be placed on an interior surface of the
bin 48, on the bottom thereof, or at any other suitable
location.
[0027] An RFID device 44, which includes a programmable chip, may
be programmed with non-variable information, such as the bin
designation (type of bin, normal usage, first use date, serial
number, or any other information desired), as well as variable
information which changes each time the bin 48 completes a defined
task (that is when it reaches a destination station). During each
use it is also programmed with variable information, which contains
at least one or two of the origin of the bin 48, the contents of
the bin 48 (that is the objects or material held thereby), its
ultimate destination, position information (for tracking the
position of the bin 48 and where it is to be at certain points of
time), and/or any other information desired. The programmable chip
of the conventional RFID device 44 may then be re-programmed with
other variable information (canceling out the initial variable
information) throughout the entire life of the bin 48, label 43, or
RFID device 44, which of the components wears out first being
dependent upon the particular process and components involved.
[0028] Two other ways that an exemplary label according to the
present invention, which preferably is substantially water or
moisture impervious, can be constructed are illustrated
schematically at FIGS. 7 and 8.
[0029] In FIG. 7 conventional paper stock (such as bond or card
stock) 50 having indicia 45 thereon and an RFID device 44 embedded
therein or mounted thereon, is sandwiched between two pieces of
plastic substantially moisture impervious film 51, 52, at least the
film 51 being transparent so that the indicia 45 is visible. The
films 51, 52 may be held to the paper stock 50 by permanent
adhesive or in any other suitable manner. On the back of the film
52 is permanent pressure sensitive adhesive 30 which attaches the
final label 53 of FIG. 7 to the bin 48 or other reusable
container.
[0030] FIG. 8 which schematically illustrates an embodiment having
stock 55 that is itself substantially moisture impermeable, such as
TESLIN having an RFID device 44 mounted thereon or embedded
therein, and having pressure sensitive permanent adhesive 30 on the
back face thereof, has a plastic or other moisture impervious film
56 applied thereover. The film 56 may be transparent or opaque, and
if opaque has indicia 45 thereon (and if transparent the indicia 45
typically will be on the stock 55). The film 56 is held to the
stock 55 with conventional permanent adhesive or in any other
suitable manner, to produce a final label 57 which is used just
like the label 43 as described above.
[0031] It will thus be seen that according to the present invention
an advantageous method of labeling reusable containers, and
reusable containers produced thereby, have been provided which have
a number of advantages compared to conventional methods and
systems. The labeling system will always be permanently affixed to
the reusable container, is not easily damaged nor the information
thereon obscured, does not require the constant replacement of
material but rather is simply reprogrammed in a simple and
conventional manner, over a long life. The mounting of the RFID
device which facilitates achieving the advantages of the invention
is simple yet effective.
[0032] While the invention has been herein shown and described in
what is presently conceived to be the most practical and preferred
embodiment thereof, it will be apparent to those of ordinary skill
in the art that many modifications may be made thereof within the
scope of the invention, which scope is to be accorded the broadest
interpretation of the appended claims so as to encompass all
equivalent methods and products.
