This application incorporates by reference the entire contents of the above applications.

[0003] The various implementations generally relate to supplying roll sheet goods. [Background technology]

[0004] Sheet goods can be supplied for a variety of purposes. For example, textiles can be supplied from a roll. Paper can be supplied from a roll, for example for printing and / or packaging. Fixed sheet goods can, for example, be supplied from a roll and used to fasten an object (e.g. a package).

[0005] As an example, a stationary sheet product can include a backing material (e.g., paper, textile, polymer) and a stationary substance. The stationary substance can include, for example, an adhesive. A common form of stationary sheet is a tape. Packing tape, for example, can have a paper and / or polymer substrate layer with an adhesive layer. In some implementations, the tape can be, for example, reinforced (e.g., with filaments in one or more directions).

[0006] The tape may be dispensed, for example, using a roller. A roller may be used to bring the adhesive side of the tape into contact with the object to be taped. For example, in a shipping operation, items are packaged in a cardboard box and taped by a manual process of applying the tape. An operator cuts a length of tape from a roll (e.g., before or after application), for example, using scissors, a knife, and / or fixed teeth on a tape dispenser. Summary of the Invention [Means for solving the problem]

[0007] The apparatus and associated methods relate to a portable powered dispensing tape dispenser having a center of gravity in front of a user's hand. As a specific example, the tape dispenser may include a housing having a handle configured to be held by a human hand, for example. The first roller body may be rotatably coupled to the housing, for example, and rotate about a first axis. The motor may be disposed within the first roller body, for example. The actuator may be configured such that, in response to actuation of the actuator by a user, the motor causes rotation of the first roller body about the first axis. The second roller body may be rotatably coupled to the housing, for example, and configured to rotate about a second axis substantially parallel to the first axis. Various implementations may advantageously increase stability and / or reduce operator fatigue during a taping operation.

[0008] Various implementations may achieve one or more advantages. For example, some implementations may advantageously increase the ergonomic stability and efficiency of the tape dispenser during the taping process. In some implementations, the power train components (e.g., motor, gearing), for example, may be advantageously located forward of the handle. Thus, various implementations may advantageously position the center of gravity of the tape dispenser toward the front end of the tape dispenser. In some exemplary implementations, the center of gravity may be substantially located, for example, at the supply roller (e.g., first roller body). For example, in some implementations, a majority of the weight of the tape dispenser may be configured to rest on (e.g., be supported by) the target object (e.g., cardboard box) during the taping operation.

[0009] Thus, various implementations may reduce operator fatigue, such as by advantageously transferring the weight of the tape dispenser to a target object for support, thereby reducing the force and / or moment applied to a user's wrist.

[0010] Various implementations may, for example, advantageously increase the pressure applied by the supply roller to the target object. Such implementations may, for example, advantageously increase frictional forces between the supply roller and the tape. Some implementations may, for example, advantageously increase frictional forces between the supply roller, the tape, and / or the target object. Some implementations may, for example, advantageously increase the uniformity of pressure distribution by the supply roller against the tape.

[0011] Various such implementations may advantageously, by way of example and not by way of limitation, increase adhesion of the tape to the target object. Some implementations may advantageously, by way of example and not by way of limitation, simultaneously smoothly guide and tension the tape, reducing operator effort during the taping process. For example, some implementations may advantageously reduce or eliminate slippage of the tape against the target and / or supply rollers (e.g., due to improper friction and / or applied pressure).

[0012] Some implementations may provide for direct drive of the feed roller by a motor (e.g., by having a motor located within the feed roller). Such implementations may, by way of example and not limitation, advantageously reduce or eliminate sway (e.g., side-to-side sway) resulting from indirect drive (e.g., a motor located away from the feed roller) and / or weight distribution away from the feed roller. Various such implementations may, for example, advantageously reduce the risk of an operator injuring their wrist (e.g., with prolonged use).

[0013] In various implementations, the thermal energy generated by the motor can be advantageously transferred to a feed roller, for example. For example, a heated feed roller can advantageously increase adhesion between the tape being fed and the target object being taped.

[0014] Some implementations may advantageously operate a motorized cutter to cut the tape at a desired length. In some implementations, by way of example and not limitation, the motorized cutter may advantageously be operated by the same motor that drives the supply roller. Such implementations may, for example, advantageously reduce production costs and / or size of the tape dispenser.

[0015] The details of various implementations are set forth in the accompanying drawings and the description below. Other features and advantages will become apparent from the description and drawings, and from the claims. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Like reference numbers in the various drawings indicate like elements.

[0018] To facilitate understanding, the present specification is organized as follows. First, to facilitate introduction of the description of various implementations, a front center of gravity tape dispenser system is introduced with reference to Figs. 1A-2. Second, the introduction leads to a description with reference to Figs. 3-9 of several exemplary implementations of a motorized feed tape dispenser and tape dispenser components. Third, with reference to Figs. 10-14, an auxiliary cutter tape dispenser and its components are described. Fourth, with reference to Fig. 15, the description turns to an exemplary architecture of a motorized tape dispenser. Fifth and with reference to Fig. 16, the present specification describes an exemplary method useful for controlling a motorized tape dispenser. Finally, the present specification describes further implementations, exemplary applications and aspects related to a motorized tape dispenser.

[0019] FIG 1A illustrates an exemplary powered dispensing tape dispenser in an exemplary use case scenario, where the tape dispenser is configured with a center of gravity in front of the handle. FIG 1B illustrates the exemplary tape dispenser of FIG 1A. The portable tape dispenser 100 includes a housing. As shown, the housing includes a handle 10 and a frame 12 mounted in and on the handle 10. In the illustrated example, the handle 10 is in the form of a shaft configured to be grasped by a human hand. The handle 10 extends substantially along a longitudinal axis 105, as shown.

[0020] 2 illustrates the example tape dispenser of FIG. 1A with at least a portion of the housing corresponding to the handle removed for visibility in an example use case scenario (e.g., dispensing tape). As shown in FIG. 2, in some implementations, the handle 10 is configured to house a battery 14. As shown, in some implementations, the handle 10 may be configured to house, for example, an actuator (e.g., push button 16). In various implementations, the handle 10 may house, for example and without limitation, an electronic circuit board, a switch, an electric motor, and / or gear components. Such implementations may advantageously provide, for example, efficient use of space and / or control of the center of gravity of the portable tape dispenser 100.

[0021] 1A-1B, the main structure of frame 12 includes a main roller 30. As shown, a secondary roller (e.g., adapter 35) is included for attaching tape 31. Adapter 35 may be selectively replaceable and / or omitted depending, for example, on the configuration of the sheet goods dispensed by portable tape dispenser 100.

[0022] In some implementations, a motor (not shown) and / or drive components (e.g., gearing, belt) (not shown) may be disposed within the main roller 30. The motor may be, for example, an electric motor. The motor may be configured, for example, to drive the main roller 30 of the tape. The motor may be configured, for example, to drive the rotation of the main roller 30 at a desired speed. The speed may be controlled by, for example and without limitation, an optional speed controller (e.g., a speed controller circuit board (not shown)).

[0023] As shown, the portable tape dispenser 100 is configured such that the center of gravity 110 of the portable tape dispenser 100 is a distance D1 (e.g., a minimum distance) forward of the longitudinal axis 105 (e.g., toward the main roller 30) when the portable tape dispenser 100 is in an upright position. The main roller 30 is configured to receive the force of gravity (w t ) is larger than gravity (w m ) For example, w m may be due, at least in part, to the motor and / or gearing.

[0024] Such implementations, by way of example and not limitation, may advantageously transfer weight from the operator's hands to the target object during the taping operation. Thus, operator fatigue may, for example, be advantageously reduced. The main roller 30 may, for example, be advantageously m At least a portion of the applied force w may be applied to the target object and / or the tape 31 being dispensed from the main roller 30. Thus, the pressure distribution and / or frictional force applied to the dispensed tape 31 and / or the target object may be advantageously increased. For example, increased frictional force may advantageously reduce slippage of the tape 31 on the main roller 30. For example, increased applied force may advantageously reduce slippage of the tape 31 relative to the target object during the taping operation. A larger force w m advantageously causes lateral rocking of the portable tape dispenser 100 during taping, w tThe movement caused by the moment (e.g., torque) due to the tape may be reduced (e.g., by having a greater weight than would be applied directly to the target object), and thus, more uniform application of the tape and / or enhanced adhesion may be advantageously achieved.

[0025] In the illustrated example, adapter 35 is attached to shaft 33 and rotates about shaft 33 while supporting a roll of tape 31 thereon. In various implementations, frame 12 can be of various designs, sizes and / or shapes, for example and without limitation. Handle 10 can be positioned in various locations relative to tape dispenser 100. For example, handle 10 can be provided in various designs, sizes, orientations and / or shapes suitable for a user to assist and / or control the dispensing of tape of portable tape dispenser 100.

[0026] In some implementations, a cutter (not shown) may be included. In some implementations, a circuit board (not shown) may be included (e.g., in the handle 10).

[0027] The primary roller 30 may be configured to steer, for example, the stretching of the tape 31. In the illustrated example, the portable tape dispenser 100 includes a tape guide 3. The tape guide 3 may, for example, support and / or guide the tape as it is stretched (dispensed) by the primary roller 30. The primary roller 30 may, for example, press the tape 31 against the surface of the target object as it is being dispensed. In some implementations, for example, and without limitation, the primary roller 30 may include a hollow cylindrical drum with at least one open end.

[0028] 3 shows an exploded view of the exemplary tape dispenser of FIG. 1A , showing the main (feed) roller, rotating cap, and roller base. In the illustrated example (at least as shown in connection with FIG. 1B ), one end of the main roller 30 is connected to a roller plate 7. The roller plate 7 further connects to the frame 12 via an axle 29 as shown. In this exemplary implementation, a roller base 60 (at least as disclosed in connection with FIG. 3 ) is nested within the main roller 30. The roller base 60 may be configured, for example, as a hollow cylindrical drum that holds the gear set 19 in place (e.g., at least as disclosed in connection with FIG. 6 ).

[0029] The temperature of the surrounding environment may be at least one of the factors affecting the taping process. Higher ambient temperatures may, for example, achieve better adhesion to the target object than if the taping process were carried out at lower temperatures. Higher temperatures may promote a reaction of the adhesive when the main roller 30 is in contact with the tape 31, such as during cold weather (e.g., below 50°F, below 40°F). For example, at temperatures below 32°F, a heated application may be important to achieve problem-free adhesion of at least some of the tape to at least some of the target objects (e.g., packing tape to a cardboard box).

[0030] In some implementations, the roller base 60 may be at least partially made of a thermally conductive material (e.g., metal). Thus, the roller base 60 may advantageously conduct heat generated by the motor 18 to the body of the main roller 30 (at least as disclosed in connection with FIG. 6 ). In some implementations, for example, a conductive component (e.g., thermal paste, metal lining) may be included between the roller base 60 and the main roller 30. The conductive component, for example, may advantageously facilitate (further) heat transfer from the roller base 60 to the main roller 30.

[0031] In some implementations, a heating element may be provided and thermally coupled to the main roller 30. For example, the heating element (not shown) may be powered by the electric motor 18 and / or the battery 14 (at least as disclosed in connection with FIG. 2 ). The heating element may be thermally coupled to the main roller 30 and / or the roller base 60, for example. Thus, the heating element may advantageously provide supplemental heating to the main roller 30.

[0032] In some implementations, by way of example and not limitation, the heating elements may be selectively operated (e.g., by control circuitry) to maintain a desired temperature range (e.g., of the main roller 30). For example, in some implementations, at least one temperature sensor may be configured to monitor the temperature of the main roller 30 and / or the roller base 60. The controller may operate the heating elements in response to signals received from the temperature sensors.

[0033] 4 shows an exploded view of the exemplary tape dispenser of FIG. 1A showing the rotation cap, gear components, and roller base. In the illustrated example, the drive module includes a gear set 19, a rotation cap 20, and an electric motor 18. In the illustrated example, the rotation cap 20 is a disk including a lower tab 63 and an upper tab 62. The upper tab 62 is configured to engage a hole 39 in the wheel hub 44 (disclosed in connection with at least FIG. 3) and rotate the main roller 30. The lower tab 63 is configured to engage an eyelet 26 (e.g., an aperture, blind hole, engagement feature) in the gear set 19. In some implementations, the rotation cap 20 can be of various sizes and / or shapes while achieving the functions of the present disclosure.

[0034] Figure 5 shows an example view of the example tape dispenser of Figure 1A with at least a portion of the main roller removed to show a portion of the gear components and the roller base. Figure 6 shows an example exploded view of a portion 600 of the main roller assembly, showing the roller base, an electric motor disposed in the roller base, a gear set disposed within the roller base, and a rotation cap. Figure 7 shows an example exploded view of a main roller assembly 700, showing the roller base, an electric motor, a gear set (assembled), a rotation cap, and the main roller.

[0035] In the illustrated example, gear set 19 includes a planetary gear set. The planetary gear set includes input gear 24a, center gear 25a, planet gears 24b and 25b, and ring gear 25c. Figure 6 shows the shaft of electric motor 18 coupled to input gear 24a. Thus, when electric motor 18 is operated (e.g., activated to begin rotating), input gear 24a causes gear set 19 to move.

[0036] In various implementations, the gear set 19 may include non-planetary gears and / or gear sets to mechanically couple to the electric motor 18 to (optionally) operate the main roller 30. In some examples, by way of example and not limitation, the electric motor 18 may be directly coupled to the main roller 30. For example, an output (e.g., output shaft) of the electric motor 18 may be coupled (e.g., directly) to the main roller 30 and / or roller base 60. In some implementations, by way of example and not limitation, the electric motor 18 may be mechanically coupled to drive the main roller 30 via a belt, for example. Some examples may be pneumatically and / or hydraulically coupled between the electric motor 18 and the roller base 60 and / or main roller 30, for example.

[0037] In the depicted example, electric motor 18 is operably coupled to receive power from battery 14 via wiring system 5 (e.g., as disclosed in connection with at least FIG. 1B ). In some implementations, for example, electric motor 18 of tape dispenser 100 may be configured to be actuated when push button 16 is actuated (e.g., pressed) to an “ON” state. For example, push button 16 may be actuated to form a complete circuit between battery 14 and electric motor 18.

[0038] As shown, the position of the electric motor and gear components may be configured to, for example, adjust (e.g., increase) the overall weight of the main roller 30 of the tape dispenser 1, thereby shifting the center of gravity of the tape dispenser 1 toward the main roller 30. In some implementations, the weight of the main roller 30 may, for example and without limitation, advantageously turn the tape dispenser 100 into an effective front-heavy "squeezer" during the taping process. The additional weight of the main roller 30 may, for example, advantageously distribute the pressure applied to the tape during the taping process, as well as, for example, advantageously increase friction to move the main roller 30 over the surface of the target object. The movement of the main roller 30 may, for example, advantageously simultaneously guide and pull the tape 31 smoothly from the adapter 35. Thus, a user may, for example, advantageously hold the handle 10 and guide the tape dispenser in a desired direction with little effort (e.g., seemingly "effortlessly").

[0039] During an exemplary taping process, a user places the tape dispenser 100 on a surface of an object (e.g., a carton box). The user may, for example, engage a push button 16 located on the shaft of the handle 10. The push button 16 may, for example, when pressed by a user, connect to a circuit board to form a complete circuit. The push button 16 and / or the circuit board may, for example and without limitation, complete a circuit to provide power from the battery 14 via the input 17 (e.g., a power cable as at least disclosed in connection with FIG. 7 ). In response, the electric motor 18 may, for example, be activated and rotated. The rotation of the electric motor 18 (e.g., an output shaft of the electric motor 18) may operate gears of the gear set 19, thereby causing the rotation of the rotating cap 20. The rotation of the rotating cap 20 may, for example, drive the rotation of the main roller 30, thereby operating the main roller 30 to draw the tape 31 from the adapter 35 while simultaneously driving the tape dispenser 100 towards a direction guided by the user.

[0040] In various implementations as shown, the push button 16 can be placed at a desired location along the shaft of the handle so that it is in a position where it can be easily activated and deactivated by the fingers of a user's hand gripping the handle.

[0041] 8 illustrates an example implementation of a main (feed) roller. In some implementations, the main roller can include multiple sections, for example, as shown in FIG. 8. In the example shown in the example main roller 800, the center section 50 is a smooth section. For example, the center section 50 can be configured to pass (e.g., feed) and compress the tape 31 during operation. The side sections 51 (e.g., left and right as shown) are configured to grip as the main roller 800 drives over the surface of the package.

[0042] In various implementations, the main roller 30, main roller 800 and / or roller base 60 can be of various designs, materials, sizes and / or shapes. In some implementations, the main rollers (e.g., main roller 30, main roller 800) can be integrally formed, such as using the same material and / or surface texture, so long as they substantially continuously (e.g., smoothly) adhere the target fixing sheet (e.g., tape 31) and provide sufficient traction for the tape dispenser 100 to roll on the surface of the target object.

[0043] In the illustrated example, the tape dispenser 100 includes a mechanical adapter for the tape 31. As illustrated, the adapter 35 is not driven by a motor. In this case, the adapter 35 rotates passively as the action of pulling the tape 31 acts (e.g., simply) on the main roller. In some implementations, a motorized driven main roller 30 may be configured to drive the adapter 35, for example and without limitation. For example, during a taping process, the motor of the adapter 35 may be activated (e.g., by the battery 14) and cause a rotational motion, which in turn feeds the tape 31 to the main roller 30. Such an example may, for example, reduce the force that needs to be applied by the main roller 30 to feed the tape 31. In some implementations, for example and without limitation, a control circuit may control the speed of the adapter 35 relative to the speed of the main roller 30 (e.g., to prevent tape jams and / or to maintain a predetermined (minimum) force of the tape 31 applied to the main roller 30). In some implementations, by way of example and not limitation, adapter 35 may be of various designs, materials, sizes, and / or shapes. For example, in some implementations, adapter 35 may be configured to be of various shapes and / or designs, including, but not limited to, a rod, a roller, and / or a spring mandrel.

[0044] In some implementations, the portable tape dispenser 100 may be configured to dispense various types of sheet goods. For example, as described, the sheet goods may be fixed sheet goods. For example, the sheet goods may include a tape (e.g., tape 31). In some implementations, the tape 31 may be in the form of various materials, including, for example and not limited to, film, shrink wrap, vinyl, polyvinyl chloride (PVC), paper, rubber, and / or silicone. Various implementations may be tailored to the specific needs of, for example, a particular sheet goods and / or material. For example, the dispensing speed and / or force may be adjusted (e.g., based on the tensile strength and / or elasticity of the material). In some implementations, the diameter of the main roller 30 and / or the distance between the main roller 30 and the adapter 35 may be configured based on the material properties of the sheet goods being dispensed (e.g., thickness, diameter of the target roll being dispensed). In some implementations, the tape may include a non-adhesive sheet goods (e.g., shrink wrap, woven).

[0045] In some implementations, once a desired length of tape has been dispensed, the tape 31 may be cut off by a cutting mechanism. In various implementations, the cutting mechanism may be of various designs, materials, sizes and / or shapes. The cutting mechanism may be implemented, for example, to operate in a different manner in some implementations but still fit into the tape dispenser to perform the cutting operation.

[0046] In an exemplary method, a user places tape 31 under the cutter and presses the handle of the tape dispenser toward the taping surface, manually enabling the cutter to cut off the tape.

[0047] FIG. 9 illustrates an exemplary implementation of the main roller of FIG. 1A, showing the one-way bearing, output shaft, and wheel hub. FIG. 10 illustrates an exemplary powered feed tape dispenser with a cutter and with an at least partially open handle, and showing the battery, circuitry, shear drive, and cutter. FIG. 11 illustrates the exemplary tape dispenser of FIG. 10, showing the cutting mechanism central hub, mechanical linkage, and cutter in a retracted position (e.g., in a loading mode). FIG. 12 illustrates the exemplary tape dispenser of FIG. 10, showing the cutting mechanism central hub, mechanical linkage, and cutter in an extended position (e.g., in a cutting mode). FIG. 13 illustrates the exemplary tape dispenser of FIG. 10, with the housing and other components removed to show the gear train, gear rack, and cutter of the shear drive for selectively operating the cutter.

[0048] In some implementations, by way of example and not limitation, the portable tape dispenser 1000 includes a powered cutter 93 (e.g., as disclosed in connection with at least FIG. 10). The portable tape dispenser 1000 may be configured, for example, at least as disclosed in connection with the portable tape dispenser 100 and include at least the cutter 93. The powered cutting mechanism may be activated, for example, by a trigger 97 on the shaft of the handle. When triggered, a cutting mode and / or cutting process may be activated. In some implementations, for example, the cutting mode may be managed by a cutter circuit controller 37 of the tape dispenser 1000.

[0049] During the taping process, the top tab 62 (e.g., as disclosed in connection with at least FIG. 4) engages the wheel hub 44 (e.g., as disclosed in connection with at least FIG. 3) and rotates the main roller 30 in a forward motion (e.g., clockwise rotational direction) while the output shaft 40 is free moving. During the cutting process (e.g., when the cutting mode is activated), the electric motor 18 can be configured, for example, to rotate in a reverse direction (e.g., counterclockwise rotational direction), thereby causing the main roller 30 to move in the reverse direction as well.

[0050] The reverse motion of the main roller 30 causes, for example, a one-way bearing 42 (e.g., as disclosed in connection with at least FIG. 9 ) to engage the output shaft 40. The one-way bearing 42 may be configured, for example, to transfer torque (momentum) between the main roller 30 and the output shaft 40. When the main roller 30 rolls in a forward direction, the one-way bearing 42 causes the output shaft 40 to maintain free motion. When the main roller 30 rolls in a reverse direction, the one-way bearing 42 engages and rotates the output shaft 40, which in turn also rotates (e.g., simultaneously) the cutting mechanism center hub 95 (e.g., as disclosed in connection with at least FIG. 10 ).

[0051] In some implementations, the reverse rotation of the electric motor 18 and / or the main roller 30 may be limited, for example, to a predetermined number of revolutions (e.g., an angle of rotation, a number of revolutions, a fraction of a revolution). The predetermined rotation limit may be configured, for example, to prevent the tape 31 from sticking and / or tangling and / or jamming of the tape 31 due to reverse rotation of the tape 31.

[0052] In the illustrated example, when the cutting mechanism central hub 95 is engaged and rotated, it drives a shear drive 91. The shear drive 91 includes a mechanical element that is configured to engage and drive a cutter 93 to selectively transition (e.g., reciprocate) between an extended position (e.g., cutting mode) and a retracted position (e.g., loading mode). The action of the shear drive 91 causes a cutting edge 90 (e.g., a shaped metal edge, e.g., a serrated steel blade) mounted on the cutter 93 to (fleetingly) enter the path of the packaging tape to cut off the tape 31. FIG. 11 illustrates an exemplary shear drive. The exemplary shear drive includes a series of mechanical linkages 92 that include various interlocking portions.

[0053] In the illustrated example, the cutting mechanism central hub 95 connects to the mechanical linkage 92 via a connector 98. The mechanical linkage may, for example, convert a given input force and movement into a corresponding (e.g., desired) output force and movement. In this example, rotation of the cutting mechanism central hub 95 translates the force and movement through the mechanical linkage 92 to the cutter to perform the cutting action. Figures 11 and 12 further show the cutter 93 in retracted and extended positions, respectively.

[0054] 13, the shear drive 91 includes a gear train 94 configured to interact with a gear rack 96 positioned on a bottom surface of the cutter 93. In the illustrated example, the cutting mechanism central hub is configured as a gear. Movement of the gears in the gear rack 96 causes the cutter 93 to transition (e.g., reciprocate) between an extended position and a retracted position.

[0055] The cutting process may be controlled, for example, at least in part, according to a timer. For example, the control circuit may cause the cutter 93 to operate in a cutting mode temporarily (e.g., for a predetermined period of time). For example, once the cutting process has completed its timed cycle, the cutter 93 may enter a retracted position and remain disengaged until a cutting action is actuated by the trigger 97. The cutting process may be configured to operate for a fixed period of time, for example, as determined by the cutter circuit controller 37.

[0056] In some implementations, the cutter 93 may be operated to the cutting position for a variable amount of time (e.g., corresponding to the duration that the push button 16 is pressed by the user to activate the cutting mode). In some implementations, for example, the push button 16 may directly activate the cutting mode. In some implementations, for example, the release of the push button 16 may directly deactivate the cutting mode.

[0057] FIG. 14 illustrates the exemplary tape dispenser of FIG. 10, showing the output shaft at the rotating cap, the first one-way bearing at the main roller, and the second one-way bearing at the cutting mechanism center hub. In this illustrated implementation, rotation of the main roller (e.g., main roller 30) can be caused by driving the output shaft (e.g., instead of the engagement of the top tab 62 of the rotating cap 20 with the wheel hub 44 of the main roller). As shown in FIG. 14, the output shaft 40b is positioned on the surface of the rotating cap 20b. The one-way bearing 42a is mounted within a bore of the main roller 30b.

[0058] During the taping process, the electric motor 18 can be operated to move in a forward direction, thereby rotating the output shaft 40b, which engages the one-way bearing 42a and rotates the main roller 30b in a forward direction (e.g., a clockwise rotational direction).

[0059] A second one-way bearing 42b, which operates in the opposite rotational direction to the one-way bearing 42a, is mounted within a bore in the cutting mechanism center hub 95b. The output shaft 40b is inserted through a bore in the main roller 30b and further connects with the cutting mechanism center hub 95b.

[0060] During the taping process, the one-way bearing 42b functions in the opposite order (rotational direction) to the one-way bearing 42a, so that the cutting mechanism center hub 95b is free to move and disengage the shear drive 91 during forward movement of the main hub.

[0061] During the cutting process, the electric motor 18 runs in the reverse direction (counterclockwise), thereby rotating the rotating cap 20b and the output shaft 40b in the reverse direction. At the same time, the output shaft 40b disengages from the one-way bearing 42a, thereby allowing the main roller 30b to move in a free motion. The output shaft 40b engages with the one-way bearing 42b to rotate the cutting mechanism center hub 95b. When the cutting mechanism center hub 95b is engaged and rotates, it drives the shear drive 91 via the connector 98. The shear drive 91 thus drives the cutter 93 to reciprocate between the extended and retracted positions.

[0062] In some implementations, by way of example and not limitation, the shear drive 91 may be assembled and connected in a variety of ways so long as it reciprocates the cutter 93 (e.g., at least as disclosed in connection with FIG. 11 ) between extended and retracted positions. The cutting edges (e.g., formed metal edges), triggers, output shafts, shear mechanism central hubs, and / or mechanical linkages may be of various designs, materials, sizes, and / or shapes, for example.

[0063] In some implementations, the adapter may be replaced, for example, by attaching the tape 31 to the main roller. In this case, the adapter 35 may be omitted, for example. During the taping process, the user engages a push button on the shaft of the handle. This action may, for example, complete a circuit (e.g., to operate a motor). The electric motor may be powered by a battery and may, for example, activate and rotate a gear set located (e.g., nested) within the main roller. The rotation of the gear set may, for example, move a rotating cap in a circular motion. The rotation of the rotating cap drives the main roller, for example, to dispense and dispense tape onto the surface of an object.

[0064] 15 shows an example block diagram of an example tape dispenser implementation. The tape dispenser 1500 may include, for example, a control circuit 1505. In the illustrated example, the control circuit 1505 is coupled to an operator control 1510 (e.g., an actuator, e.g., a trigger, a switch, a push button, e.g., push button 16). The operator control 1510 may be configured, for example, to generate a signal to the control circuit (e.g., by closing a circuit, e.g., ground, to a voltage source and / or sink). The operator control 1510 may, for example, cause the control circuit to connect a power source 1515 to a motor 1520.

[0065] In the depicted example, the motor 1520 is electrically coupled to the control circuitry 1505. The power source 1515 is (e.g., selectively) coupled to the motor 1520. In some implementations, for example, the motor 1520 may be the motor 18.

[0066] In some implementations (not shown), by way of example and not limitation, the power source 1515 can be coupled to the control circuitry 1505. The control circuitry 1505 can, for example, selectively connect the power source 1515 to the motor 1520. For example, the power source 1515 can be a battery 14.

[0067] The speed controller 1525 is operably coupled to the control circuit 1505. For example, the speed controller 1525 may be a control circuit separate from the control circuit 1505. In some implementations, for example, the speed controller 1525 may be a module of and / or integrated into the control circuit 1505. The speed controller 1525 may, for example, control the speed of rotation of the motor 1520 (e.g., in response to a signal received from the operator control 1510).

[0068] The shear drive 1530 is operably coupled to the control circuit 1505. In some implementations, for example, the shear drive 1530 can be a powered cutter 93. For example, the shear drive 1530 can be powered through the control circuit 1505. In some implementations (not shown), for example, the shear drive 1530 can be coupled to a power source 1515 and actuated by the control circuit 1505. In some implementations, the control circuit 1505 can operate the shear drive 1530 in response to, for example, an input from the operator control 1510. The control circuit 1505 can determine whether to operate the shear drive 1530 in response to, for example, an input from the operator control 1510 based on a current speed of rotation (e.g., of the motor 1520). In some examples, the speed controller 1525 can be omitted, for example and without limitation. In some examples, the shear drive 1530 can be omitted, for example and without limitation.

[0069] In the illustrated example, the heating element 1535 is operably coupled to the control circuitry 1505. For example, the heating element 1535 may be configured to heat the feed rollers (e.g., main roller 30, main roller 800). The control circuitry 1505 may, for example, provide power to the heating element 1535 from a power source 1515. In some implementations (not shown), for example and without limitation, the heating element 1535 may be coupled to the power source 1515, and the control circuitry 1505 may selectively operate the heating element 1535. The control circuitry 1505 may, for example, operate the heating element 1535 in response to input from a user (e.g., heater on, heater off, auxiliary heating mode on / off) and / or input from a sensor (e.g., temperature sensor). In some examples, the heating element 1535 may be omitted, for example and without limitation.

[0070] In the illustrated example, one or more sensors 1540 are operably coupled to the control circuitry 1505. For example, a speed sensor may determine the speed of rotation of the motor 1520 and / or roller. A position sensor may determine the position (e.g., linear distance, angle) of the roller and / or motor 1520, for example. In some implementations, for example, a temperature sensor may determine the temperature of the dispensed sheet item (e.g., tape 31), the target object and / or the roller (e.g., main roller 30, main roller 800). In some implementations, the sensor may detect, by way of example and without limitation, the presence of an operator (e.g., a proximity sensor and / or a switch in a handle) and / or the taping process (e.g., a force sensor, pressure sensor, displacement sensor that detects engagement of the dispense roller with the target object). In various implementations, the control circuitry 1505 may operate the motor, shear drive, speed controller and / or heating element in response to signals from the one or more sensors 1540, for example. In some examples, one or more of the sensors 1540 may be omitted, for example and without limitation.

[0071] 16 shows an exemplary flow chart illustrating an exemplary method of controlling the operation of a tape dispenser with a motorized feed roller. In the exemplary method 1600, at step 1605, a feed signal is received (e.g., by control circuitry such as control circuitry 1505) from an operator input (e.g., operator control 1510). At step 1610, a signal is generated (e.g., by control circuitry such as control circuitry 1505) to operate a motor (e.g., motor 1520, motor 18) in a first rotational direction to feed tape. If at decision point 1615, it is determined that the feed signal is still being received, the signal continues to be generated at step 1610. Otherwise, method 1600 proceeds to decision point 1620.

[0072] If at decision point 1620 it is determined that a cut signal is received (e.g., from an operator input, from an automatic sensor such as a travel speed sensor, a force sensor, etc.), then at step 1625 a signal is generated to operate the shear drive (e.g., shear drive 1530) to enter a cut mode and cut the tape. Otherwise, method 1600 ends.

[0073] Although various implementations have been described with reference to the drawings, other implementations are possible. For example, various implementations may be configured to be at least partially supported by a human hand. Some implementations may be configured to be supported (e.g., carried, operated) entirely by a human hand (e.g., in conjunction with a target object), by way of example and not limitation. Various such implementations may be configured with a housing configured to be engaged (e.g., held between fingertips, grasped, held), for example, by a human hand. For example, some examples may include a handle. In some examples, the housing may be sized and / or shaped to be grasped by a human hand.

[0074] In some examples, the first roller body and / or the second roller body may be movably coupled to a housing (e.g., a frame member). For example, the first roller body may be coupled to the housing by a spring. As a specific example, the first roller body (e.g., including a motor) may be coupled to the housing by a "mousetrap" (e.g., a spring-loaded bar) and the first roller body is biased downwardly (e.g., from a retracted loading position) toward a feed position. The first roller body may be biased, for example, toward one or more feed members (e.g., a secondary roller, a support bar).

[0075] In some implementations, the first roller body and / or the second roller body can be of various sizes. For example, the outer rollers and / or cores can be interchangeable (e.g., with different sizes). In some examples, the roller body can include spokes (e.g., configured to engage a roll of sheet goods). The spokes can be, by way of example and without limitation, of various diameters and / or orientations (e.g., collapsible, telescoping, flexible, e.g., with a variable radius of curvature).

[0076] Although an example system has been described with reference to the drawings, other implementations may be deployed in other industrial, scientific, medical, commercial and / or residential applications.

[0077] In various implementations, some bypass circuit implementations may be controlled in response to signals from analog or digital components that may be separate, integrated, or a combination of each. Some implementations may include a programmed programmable device or some combination thereof (e.g., PLA, PLD, ASIC, microcontroller, microprocessor) that provides single or multi-level digital data storage capabilities and may include one or more data stores (e.g., cells, registers, blocks, pages) that may be volatile, non-volatile, or some combination thereof. Some control functions may be implemented in hardware, software, firmware, or any combination thereof.

[0078] A computer program product may include a set of instructions that, when executed by a processor device, causes the processor to perform certain functions. These functions may be performed in conjunction with controlled devices in operative communication with the processor. A computer program product, which may include software, may be stored in a data store tangibly embodied in a storage medium, such as an electronic, magnetic, or rotating storage device, and may be fixed or removable (e.g., hard disk, floppy disk, thumb drive, CD, DVD).

[0079] With reference to the figures above, examples of systems that may be portable have been described, although other implementations may be deployed in other processing applications, such as desktop and networked environments.

[0080] Temporary auxiliary energy input may be received, for example, from a rechargeable or disposable battery, which may enable use in portable or remote applications. Some implementations may operate from other DC voltage sources, such as a 9V (nominal) battery. Alternating current (AC) input, which may be provided, for example, from a 50 / 60Hz power port or a portable generator, may be received through a rectifier and appropriate scaling. Providing an AC (e.g., sine wave, square wave, triangle wave) input may include a line frequency transformer to step up the voltage, step down the voltage, and / or provide isolation.

[0081] Although certain features of the architecture have been described, other features may be incorporated to enhance performance. For example, caching (e.g., L1, L2, ...) techniques may be used. For example, random access memory may be included to provide scratch pad memory and / or to load stored executable code or parameter information for use during run-time operations. Other hardware and software may be provided to perform the operations, such as network or other communications using one or more protocols, wireless (e.g., infrared) communications, stored operating energy and power supplies (e.g., batteries), switching and / or linear power supply circuits, software maintenance (e.g., self-test, upgrades), etc. One or more communications interfaces may be provided in support of data storage and related operations.

[0082] Some systems may be implemented as computer systems that may be used with various implementations. For example, various implementations may include digital circuitry, analog circuitry, computer hardware, firmware, software, or a combination thereof. An apparatus may be implemented in a computer program product tangibly embodied in an information carrier, such as a machine-readable storage device, for execution by a programmable processor, and a method may be executed by the programmable processor executing a program of instructions to perform the functions of the various implementations by operating on input data and generating output. Various implementations may be advantageously implemented in one or more computer programs executable on a programmable system that includes at least one programmable processor coupled to receive data and instructions from, and transmit data and instructions to, a data storage system, at least one input device, and / or at least one output device. A computer program is a set of instructions that may be used directly or indirectly in a computer to perform some activity or bring about some result. A computer program may be written in any type of programming language, including compiled or interpreted languages, and may be deployed in any form, such as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment.

[0083] Processors suitable for executing a program of instructions include, by way of example, both general purpose and special purpose microprocessors, which may include a single processor or one of multiple processors of any type of computer. Typically, a processor receives instructions and data from a read-only memory or a random access memory or both. The necessary elements of a computer are a processor for executing instructions and one or more memories for storing instructions and data. Typically, a computer also includes, or is operatively coupled to communicate with, one or more mass storage devices for storing data files, such devices including magnetic disks, e.g., internal hard disks and removable disks, magneto-optical disks and optical disks. Storage devices suitable for tangibly embodying computer program instructions and data include all types of non-volatile memory, e.g., semiconductor memory devices, e.g., EPROM, EEPROM and flash memory devices, magnetic disks, e.g., internal hard disks and removable disks, magneto-optical disks, and CD-ROM and DVD-ROM disks. The processor and memory may be supplemented by, or incorporated in, ASICs (Application Specific Integrated Circuits).

[0084] In some implementations, each system may be programmed with the same or similar information stored in volatile and / or non-volatile memory and / or may be initialized with substantially identical information. For example, one data interface may be configured to perform auto-configuration, auto-download and / or auto-update functions when coupled to an appropriate host device, such as a desktop computer or server.

[0085] In some implementations, one or more user interface features can be customized and configured to perform specific functions. Various implementations can be implemented in a computer system that includes a graphical user interface and / or an Internet browser. To provide for user interaction, some implementations can be implemented in a computer having a display device, such as a CRT (cathode ray tube) or LCD (liquid crystal display) monitor, for displaying information to the user, a keyboard and a pointing device, such as a mouse or trackball, for allowing the user to provide input to the computer.

[0086] In various implementations, the system may communicate using suitable communication methods, equipment, and technologies. For example, the system may communicate with compatible devices (e.g., devices capable of transferring data to and / or from the system) using point-to-point communication, where messages are transmitted directly from source to receiver over a dedicated physical link (e.g., fiber optic link, point-to-point wiring, daisy chain). The components of the system may exchange information by any form or medium of analog or digital data communication, including packet-based messages over a communication network. Examples of communication networks include, for example, a LAN (local area network), a WAN (wide area network), a MAN (metropolitan area network), wireless and / or optical networks, computers and networks forming the Internet, or some combination thereof. Other implementations may transmit messages by broadcasting to all or substantially all devices coupled by the communication network, for example, by using an omnidirectional radio frequency (RF) signal. Still other implementations may transmit messages characterized by high directionality, such as an RF signal transmitted using a directional (i.e., narrow beam) antenna, or an infrared signal that may be used, optionally with focusing optics. Still other implementations are possible using suitable interfaces and protocols such as, by way of example and without limitation, USB 2.0, Firewire, ATA / IDE, RS-232, RS-422, RS-485, 802.11 a / b / g, Wi-Fi, Ethernet, IrDA, FDDI (Fiber Distributed Data Interface), token ring networks, frequency, time or code division based multiplexing techniques, or some combination thereof. Some implementations may optionally incorporate features such as error checking and correction (ECC) for data integrity or security measures such as encryption (e.g., WEP) and password protection.

[0087] In various implementations, the computer system may include an Internet of Things (IoT) device. An IoT device may include objects embedded with electronics, software, sensors, actuators, and network connectivity that allows these objects to collect and exchange data. An IoT device may be used with wired or wireless devices by sending data to another device through an interface. An IoT device collects useful data and then autonomously streams the data between other devices.

[0088] Various examples of modules may be implemented using circuitry including various electronic hardware. By way of example and not limitation, the hardware may include transistors, resistors, capacitors, switches, integrated circuits, other modules, or some combination thereof. In various examples, the modules may include analog logic, digital logic, discrete components, traces fabricated on silicon substrates including various integrated circuits (e.g., FPGAs, ASICs), and / or memory circuits, or some combination thereof. In some implementations, the modules may include execution of preprogrammed instructions, software executed by a processor, or some combination thereof. For example, various modules may include both hardware and software. In an exemplary aspect, the tape dispenser may include a housing having a handle configured to be held by a human hand. The tape dispenser may include a first roller body rotatably coupled to the housing and configured to rotate about a first axis.
