These and further features and advantages of the invention will become more clearly understood in light of the ensuing description of a preferred embodiment thereof, given by way of example only, with reference to the accompanying drawings, wherein
The present invention is a new design for a portable electronic hand-held label dispenser 10 that can be adjusted to dispense labels 24 of various widths, and which additionally incorporates a unique sensor method for determining the length of each label 24 and precisely advancing the roll of labels 24 according to the captured data. A further feature of the present invention is a novel slotted uptake wheel 20 that efficiently collects the paper backing 25 for easy disposal. Additionally, the present invention can be equipped with an optional printer 14.
All of the components of the present invention reside within a housing and are accessible by removing a detachable cover 12.
In the preferred embodiment of the present invention, sensor mechanism 16 determines the length of labels 24 by scanning both the front and the back of a roll of labels 24 and identifying distinguishing marks located on individual labels 24 that indicate the length of each label. These distinguishing marks may be, inter alia, the gaps located between each label 24 or scannable distinguishing marks, such as incremental black lines, printed on paper backing 25 of labels 24. The distinguishing marks may be positioned to indicate, for example, the end of one label and the beginning of a subsequent label. Unlike prior art devices, this sensor mechanism 16 is able to identify the intervals between sequential labels 24 even where the intervals are so small as to be seemingly non-existent by scanning the imprinted distinguishing marks. These unique scannable distinguishing marks allow sensor mechanism 16 to identify precisely the length of each label 24 and determine exactly how far to advance the roll of labels 24 in order to accurately dispense a single label 24 at a time. The imprinted distinguishing marks allow labels 24 to be positioned on the backing paper with no gaps between labels. As a result, less paper backing 25 is required and the roll of labels 24 will be more compact, or conversely, more labels 24 may be placed on paper backing 25.
In some alternative embodiments of the present invention, sensor mechanism 16 is able to sense the presence of magnetically recognizable material, wherein the distinguishing marks comprise magnetically recognizable material inserted into paper backing 25 or labels 24. In yet other embodiments, sensor mechanism 16 is a touch sensor that senses when a label 24 finishes separating from paper backing 25 to determine the length of labels 24.
A removable uptake wheel 20 is centrally located in the upper portion of label dispenser 10 and receives the discarded paper backing 25 from discharged labels 24. An engine turns uptake wheel 20, which in turn drives feed wheel 18, pulling the roll of labels 24 throughout label dispenser 10. Uptake wheel 20 is also equipped with innovative slots 21, seen in
A removable lower guide plate 28, together with a fixed upper guide plate 26, functions to direct labels 24 out through an opening while directing discarded paper backing 25 up to uptake wheel 20. The width of lower guide plate 28 corresponds to the width of labels 24. Lower guide plate 28 can be replaced with plate extensions 29 to accommodate wider labels 24.
Label dispenser 10 is further equipped with a plurality of extendable pins 30 that guide labels 24 through label dispenser 10. Pin extensions 31 can be attached to each pin 30 in order to accommodate labels 24 with wider widths.
Finally, a handle 22 allows the user to comfortably grip label dispenser 10. Handle 22 is mounted on a track that allows handle 22 to move left and right according to the current width of label dispenser 10 in order to compensate for the change in balance when adjusted for wider or narrower labels 24.
A significant feature of the present invention is that, although hand-held label dispenser 10 is configured to fit labels 24 of a fixed minimum width, the invention can easily be adjusted to accommodate labels 24 of wider widths. This is accomplished by lengthening pins 30 and replacing lower guide plate 28, as shown in
In an alternative embodiment, hand-held label dispenser 10 is equipped with an optional printer 14. In such embodiments, said optional printer 14 also resides in the upper portion of label dispenser 10. Optional printer 14 uses existing technology to print user-defined messages onto individual labels 24.
A general description of the process for preparing and operating the preferred embodiment of the present invention is as follows.
Cover 12 is removed and pins 30 and lower guide plate 28 are configured according to the width of labels 24 to be used, affixing pin extensions 31 and plate extensions 29 as required. The roll of labels 24 is placed on feed wheel 18. Labels 24, still attached to paper backing 25, are then threaded over pins 30 in the upper portion of the present invention, under the head of optional printer 14, and through sensor mechanism 16. Labels 24 continue down under the subsequent pins 30, between upper guide plates 26 and lower guide plates 28, and in front of roller 33 on the front most pin 30, which assists in separating labels 24 from paper backing 25. Paper backing 25, with labels 24 dispensed, then doubles back under both lower guide plate 28 and the final pin 30 and is secured in slots 21 of uptake wheel 20. Once the threading is complete, rubber guides 32 are placed on each pin 30. Rubber guides 32 can be laterally adjusted on pins 30 in order to fit snuggly along the edge of paper backing 25, further directing labels 24 and paper backing 25 to remain in place throughout the length of the run between feed wheel 18 and uptake wheel 20. Lastly, cover 12 is replaced.
When the user presses the electronic switch located on the edge of the front of label dispenser 10 against a surface in order to dispense a new label 24, the following actions occur. A label 24 is dispensed from label dispenser 10. Uptake wheel 20 advances the roll of labels 24 until sensor mechanism 16 identifies the distinguishing mark at the end of a label 24 indicating that the roll has been advanced the full length of a single label 24. Uptake wheel 20 also rotates to capture discarded paper backing 25. In an alternative embodiment where a printer 14 is installed, a new label 24 will be printed at this point. Once sensor mechanism 16 determines that the end of a label 24 has been reached, uptake wheel 20 stops advancing the roll of labels 24. These actions are repeated for each depression of the electronic switch.
Electronic label dispenser 10 is operated by rechargeable batteries located within handle 22 of the device in the preferred embodiment. In some embodiments, there is also the option of using other sources of power.
While the above description contains many specifics, these should not be construed as limitations on the scope of the invention, but rather as exemplifications of the preferred embodiments. Those skilled in the art will envision other possible variations that are within the scope of the invention. Accordingly, the scope of the invention should be determined not by the embodiment illustrated, but by the appended claims and their legal equivalents.
