Abstract
A modular, scalable sorting assembly for sorting items into boxes, comprising two sorting level units, each unit having accessible work spaces on both front and back sides, and with a work surface dividing each unit into upper and lower storage areas with through-slots formed into a lower storage area of each unit sized and shaped to store and receive one or more uniformly sized and shaped open top boxes. The upper storage area has a series of shelves sized and shaped to store items prior to sorting or after being sorted but prior to placement in the boxes. One of the two units is further comprised of a central workstation and a wing with a side wall configuration that angles the wing towards an area directly in front of the central workstation when the wing is positioned immediately adjacent thereto.
Description
BACKGROUND OF THE INVENTION
Field of the Invention

The present invention pertains to apparatuses used in the field of sorting numerous miscellaneous unsorted print and nonprint items in the form of books, magazines, LPs, cassettes, and compact discs. Specifically, the invention is a modular, scalable sorting assembly for efficient and systematic organization of relatively large quantities of print, and digital and analogue media items.


Background Art

Used books, magazines, and audio and/or visual media in the form of vinyl records, compact discs and VHS tapes are uniquely problematic for libraries and other entities collecting such items in order to resell them to others for fundraising purposes. Each used item must be manually identified by title, then organized into like groupings. The nature of used books and media is such that the items are all individualized, meaning they differ in subject matter, condition, price, age, and size and hence are neither easily nor practically sorted by automated sorting machines or systems. In relatively small quantities, such as less than a hundred items, used media are manually sorted by one or two individuals using existing software to scan and retrieve basic information about the item, including current pricing for the used item based on its identification, age and condition, and then the item is physically positioned in a designated box or pile of same or like items. If the item is going to be sold, the grouping may be for items of a same price (all items $5 for instance), a same type of item (music cds, or magazines, for instance), a same subject (history books, for instance), or any other type of useful grouping. This manual process is easily performed on a table, where like items are simply grouped together according to their desired groupings after each item is identified and sorted.


The problem with this manual process is that it is not easily or efficiently scalable to accommodate large volumes of media, such as when many hundreds or thousands of books, magazines, movie and music CDs, VHS tapes and vinyl records must be sorted and grouped. Manually sorting large volumes using known methods requires ample space and considerable physical labor. For a charity or other non-profit organization trying to hold a fundraiser, a used book and media sale with thousands, tens of thousands, and hundreds of thousands of used items can easily require a team of 30 or more people working several hours a day in a warehouse to sort the items for weeks. Worse, item sorting must be done prior to the sale, and typically this has resulted in all sorting being performed at the sale site, presenting logistical problems when the sale site lacks the space or manpower needed to sort the items, or when that space is required for other activities prior to the sale and cannot be cordoned off to allow the sorting to take place.


Additionally, used items are typically sold at a discounted price, and profit is difficult in circumstances where the organization lacks unpaid workers as the cost of paying workers to sort and group the used items may cost as much or more than the money that will be made by the sale of the sorted items. Hence, a used book and media sale often becomes a “rummage sale”, where ungrouped and unsorted items are offered for sale and potential buyers must do the work of sorting and picking through the items. It is well known that presorting and presenting used books and other media for sale in organized and systematic ways increases sales, and hence the library or other entity holding the sale must carefully weigh the time and cost required to manually sort the items, and the desire to maximize sales.


What is needed is a sorting assembly that allows two or more people to systematically and efficiently sort and group large quantities of books and other physical media in a limited space.


What is also needed is a sorting assembly that is easily scalable to accommodate book and media volume and number of workers as needed.


What is also needed is a sorting assembly that is modular and transportable and thus easily adapted to any space as needed.


DISCLOSURE OF INVENTION

In a first aspect of the invention, a sorting assembly according to the invention is comprised of a first level sorting unit and a second level sorting unit. Either unit can be used alone to provide a single level or sorting, or more typically, the units are used together, along with a display unit and a storage unit after sorting is complete.


In a second aspect of the invention, the first level sorting unit features a doubled sided workstation with an upper shelving area for storage of sorted items, a work surface, and a series of slots sized and shaped to receive two boxes. A shelf for a computer is positioned centrally on each side of the first level sorting unit, with overhead lighting and power built into the unit. The second level sorting unit features a central station flanked by a pair of wing units angled to create a concave workstation such that a user standing in front of the central station can easily turn and access each wing efficiently. The second level sorting unit features upper shelving for sorted items and lower shelving or through slots sized and shaped to receive the boxes used in the first level sorting unit. The second level unit, like the first level unit, is fully accessible from either side and thus both units must be positioned away from a wall to allow the user access to both sides.


In a third aspect of the invention, the first level sorting unit is comprised of a pair of opposed lower side walls having a first edge shape towards the front work side and a second edge shape towards the back work side, allowing the user to visually identify each side of the unit.


In a fourth aspect of the invention, the second level sorting unit is modular and additional central stations and wings can be added as desired.


In a fifth aspect of the invention, the sorting assembly components are wheeled, allowing the units to be easily moved to accommodate different room sizes and area where sorting is occurring. The modular nature of the assembly allows the user to quickly set up, sort, and demobilize the units. The storage and display units, also wheeled, allow the user to set up a display for a sale quickly and easily, as well as breakdown the sale equally quickly.

DETAILED DESCRIPTION

A sorting assembly according to the invention 100 is comprised of a first sorting unit or GAP unit 10 and a second sorting unit or SD unit 40, the assembly 100 shown in a top view in FIG. 13, with its individual components shown in more detail in FIGS. 1-9, with storage and display assemblies according to the invention shown in FIGS. 10-12.


Items typically sorted by the sorting assembly 100 are print and digital media such as books, magazines, movie DVDs, CDs, LPs, comics, and cassettes providing a user multiple levels of sorting and the ability to quickly and efficiently sort items to a degree similar to what is found in a library or a bookstore, where books and other items are commonly grouped by subject, author, audience age, etc. The storage and display assemblies 6062 in FIGS. 9-12 allow the sorted items to be systematically stored, displayed and a sale set up and taken down quickly and easily.


Turning to the GAP unit 10 in FIGS. 1-5, the GAP unit 10 is a freestanding unit having a front side and a back side, an upper area and a lower area, the upper and lower areas separated by a front work surface 24a. The GAP unit 10 is provided with wheels 10a such as casters or other suitable wheels that allow the unit 10 to be moved as needed. The front side upper area is comprised of a plurality of shelves 18, including a centrally located workstation shelf 12 for supporting a computer 14 or other equipment. One or more power outlets 12a including USB and other useful ports are built directly into the GAP unit 10 to power lights 12b, equipment and other electronics. The shelves 18 span at least 30% of a length measurement of the GAP unit 10, and in the Figures is shown as being about ⅔ of the length measurement. The shelves 18 are minimally at least 11 inches deep, which is a standard shelf depth. Shelves 18 can be configured to be deep enough to securely hold vinyl record sleeves, for instance, or other bulky items. The front work surface 24a is sized and shaped to efficiently hold a plurality of sorted item boxes or boxes 22.


In the Figures, the boxes 22 are uniformly sized and shaped, with a box length 24d, a box width 24e, and a box height 24f. Boxes 22 shown in the Figures are rectangular in cross section i.e. cuboid, with the box length 24d dimension being larger than the box width 24e however square boxes i.e. cubes, could be used in some applications where all 4 sides have a same dimension and the slot 34 size, front and back work surfaces, etc. adjusted accordingly. Side walls of the box 22 must be of a durable enough construction to support the box 22 and its contents 20 when positioned on the box length 24d. The boxes 22 feature a lidless, open top and have a group designation 22a on each box 22 and in the Figures, the group designation is shown as numbers but note that it could also be colors, words, or other ways of differentiating the boxes from one another. In contrast, an unsorted item box 20b, holding unsorted items 20a, are typically cardboard boxes or other boxes of varying sizes and materials used simply to collect the unsorted items.


The front work surface 24a has a depth approximating one side of the box 22, and a length sized to efficiently accommodate a plurality of immediately adjacent boxes 22. The front work surface 24a plus a height of the box 22 together approximate a same height as a standard kitchen countertop to provide a comfortable work surface height. In practice, the height of the box 22 is tall enough to accommodate a majority of common book sizes. Below the front work surface 24a, the lower area is comprised of a series of vertically and horizontally adjacent through-slots or slots 34 sized and shaped to receive at least one and a maximum of two immediately adjacent boxes 22 positioned linearly within the slot 34. Boxes 22 are stored in the slots 34 where they are accessible from the front and back sides of the GAP unit 10.


The back side of the GAP unit mimics the front side, with an upper area featuring the plurality of sorting shelves 18 and an additional workstation 26 positioned centrally to allow items to be further sorted and processed. Note that the upper area of the back side of the GAP unit 10 can identically mimic the front side, and is designed for other equipment such as a printer (not shown) to be supported on the workstation shelf 12 for printing labels 26a, invoices or other information relating to the sorted items. The back work surface 24b is about 1 inch deeper than the width of the box 22 to allow secure positioning on the back work surface 24b. The back work surface 24b is also about 1 inch higher than the front work surface 24a, with the back work surface 24b taller so as to allow access to the uppermost wall of the box 22 sitting on the front work surface 24a as shown in FIG. 4. The Figures show the back work surface 24b having a raised central ledge portion 24c with space directly beneath to accommodate the box 22, drawer style.


Looking at FIG. 4, the GAP unit 10 is shown with a vertical upper side wall 30 supporting the plurality of sorting shelves 18 and a lower side wall 36 having an angled wall or edge 32 sloping downwards on the front side of the GAP unit 10. The front work surface 24a on the front side of the GAP unit 10 is lower relative to the height of the back work surface 24b on the back side of the GAP unit 10 by about 8¾ inches, slightly more than the height of the box 22. This height difference is designed to ensure the user (not shown) has a same comfortable working surface height on either side of the GAP unit 10. Note that all the approximate stated sizes in this disclosure are based on dimensions of a Buckhorn box, made by Buckhorn Inc, with a website at https://buckhorninc.com. The particular box used here is model SW241608, with the following dimensions 24″×15″×7″. In the GAP unit 10, the slots 34 are sized and shaped so as to position the Buckhorn box with its 24″ side oriented so as to be parallel to a slot length, thus with a typical slot 34 using this box being about 48″ long, between 15.5″ to 16.5″ wide and at least 7″ tall. This particular Buckhorn box was used during testing and is the basis for the dimensions of the separate units 1040 of the sorting assembly shown in the Figures and described herein. The angled wall 32 sloping along the front side of the GAP unit 10 allows the user to visually differentiate between front and back sides, and is one example of how the front and back sides can be easily identified. Alternatively, the lower side wall can have a same profile front and back, and each side labelled can be used to designate front and back, or different colors used, so long as visual differentiation is achieved. The inventor believes angling the side wall is an elegant design solution to identification.


Turning to FIGS. 6-12, the second sorting unit or SD unit 40 is shown as being comprised of a central workstation 42 having a front side with a work surface 50, an optional drawer 52 for storing miscellaneous useful items such as writing utensils, a plurality of upper sorting shelves 42a, and a plurality of lower sorting shelves 42b for box 2220b storage. In a typical configuration, the central workstation 42 is flanked on either side by a side wing workstation or wing 44 having sorted item shelves 42a and lower shelves 42b or slots 34 holding GAP sorted items 20 but instead of a work surface, each wing 44 is typically designed as storage of sorted items. When positioned together, the wings angle inwards to create an approximately concave station, its shape providing more efficient accessibility by the user standing at the central workstation 42 by minimizing travel of the user handling SD unit sorted items 20. The inventor notes that more wings 44 and central workstations can be added, as needed, to more quickly sort items by accommodating more users. The SD unit 40 is configured like the GAP unit 10 to be accessible from both the front side and a back side. The sorting shelves 42a are open on both the front and back sides of the SD unit 40 and temporarily store sorted items 20. In embodiments where the lower shelves are in fact slots 34, the boxes 20b 22 can be stored or accessed from either side.


After sorting items with the SD unit 40, the sorted items 20 are moved into boxes 22 and positioned immediately into the storage unit 62 for longer term storage, or into display units 60 ready for sale, as shown in FIGS. 10-12. The sorted items 20 in the display unit 60 are conveniently visible for sale purposes and easily removed when the sale is finished and the boxes 22 are stored in the storage unit 62. The inventor notes that the display unit 60 is typically on wheels 10a to allow easy moving of the unit 60, and also that as an alternative embodiment, the display unit 60 may be a comprised of a wheeled base sized and shaped to receive a plurality of boxes 22 stacked on top of one another such that an open side of the box is positioned sideways to allow access to its contents. The storage unit 62 may be comprised of a plurality of drawer slots as shown in FIG. 11, or alternatively, be configured as long shelves with a depth compatible with the box 22 length to allow the boxes 22 to be accessed easily.


The boxes 22 used by the GAP unit 10, SD unit 40, display unit 60 and storage unit 62 are uniform in size and shape and have no lids. The boxes 22 shown in the Figures are stackable and strong, made of structural plastic and are similar to plastic milk crates. The inventor likes the Buckhorn box, but also believes any set of uniformly sized and shaped strong boxes can be used and the boxes shown are one size and shape that worked well during testing. For the embodiment where the boxes 22 themselves form the display unit 60, opposed side of the boxes can be constructed with mating structures to allow the boxes to stack securely atop one another and allow fast build up and break down of the units 60. The inventor believes the boxes 22 could also be made of cardboard, such as banker's boxes or standard sized file boxes, however, he stresses that any box used must be strong enough to withstand the weight of the items and not crush or fall apart when sitting on its side in a display orientation as shown in FIG. 10. A plurality of boxes whose dimensions differ from those of the Buckhorn box would require modification of the sorting assembly's various units. From the inventor's perspective, no other type of box works as well as the Buckhorn box.


The GAP unit 10 and the SD unit 40 are designed to be used together to provide a minimum of two levels of sorting for the items and the type of sorting parameters used are selectable by the user. For instance, the GAP unit 10 as shown in the Figures is used to for a first level of sorting of items, such current market value. The SD unit 40 is then used to sort the first level sorted items using another grouping designation, for instance, reading level.


The inventor stresses that his sorting assembly 100, minimally comprising the GAP unit 10 and the SD unit 40, is shown in the Figures as sorting items 2020a identified as books and other print type media. Items 2020a include a wide variety of physical things, including toys, collectibles such as teacups, figurines and other things. The user is free to decide as to the type of grouping designations desired and use the GAP unit 10 and SD unit 40 accordingly. The inventor notes that it is possible to use just the GAP unit 10 or the SD unit 40 separately without the other however the use of both together provides superior sorting by allowing relatively small numbers of people (minimally two) to efficiently sort and process thousands of items using two-level sorting criteria in days rather than weeks, and then set up and tear down a book or other sale with the sorted items quickly with minimal effort and chaos. Sorting and organizing of items can thus be done offsite of the sale location, then quickly set up with the boxes 22 positioned in the display units 60. Both the GAP unit 10 and the SD unit 40 enable a pair of users to work simultaneously at the same unit. The number of GAP units 10 and SD units 40 is increased to accommodate larger volumes of material to be sorted as well as number of users, hence the sorting assembly 100 is scalable. A single GAP unit 10 can for instance be paired with multiple SD units 40, or vice versa, and the SD units 40 can include 3 or more wings or multiple central workstations and wings as needed. The sorted items 20 arranged in the display units 60 allows a bookseller or other seller to visually estimate sales with a simple glance at the number of empty boxes and their identifying groupings, such as price, type of item, etc. in a way that the currently used manual systems cannot so easily accomplish. The rolling units 10406062 allow the user to sort items and set up or tear down a book or miscellaneous item sale in virtually any convenient location that is large enough to accommodate the sorting assembly, and to arrange the units as needed to accommodate the dimensions of the room as well as the needs of the users doing the sorting work.


It is to be understood that the above-described arrangements are only illustrative of the application of the principles of the present invention. Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the scope of the present invention. For instance, the inventor notes that the modular nature of the sorting assembly 100 allows item sorting to be scaled up or down as needed, and thus any number of GAP units, or SD units and wings may be used together. The sorting assembly 100 shown in the Figures shows a basic or typical arrangement, but the modular nature of the assembly allows for many variations. The inventor also notes that the computer shelf 12 does not need to hold a computer, but rather could be a touch screen display or other equipment, such as a printer, as needed for sorting items, or even a camera. The inventor uses his assembly for sorting books, vinyl records, magazines and other media, but it can be easily used to also sort toys, housewares, figurines, trading cards, and even clothing, and all within a same unsorted box. Hence, purchasing lots from estate sales are easily sorted using the assembly and the entire process of sorting, displaying, selling and removing the unsold items can be done easily and quickly on site or in another location. The inventor also believes that wheels on the units allow for easy arrangement and transport of the assembly, however the units could also be adapted to have feet suitable for sliding that would allow the units to be easily moved.
