[0004] Sheet goods dispensers are utilized in various industries to facilitate the application of materials such as paper, film, foil, and fabric. Some examples of sheet goods dispensers include roll-fed dispensers, which may, for example, support a roll of material and allow for continuous feed. In some examples, sheet-fed dispensers may handle pre-cut sheets for individual dispensing. Gravity-fed dispensers may, for example, rely on the weight of the material to advance sheets. In some embodiments, motorized dispensers may automate the feeding process for increased efficiency. Some examples may include manual dispensers, which may require user intervention to advance and cut the material.

[0005] Tape dispensers are a specific category of sheet goods dispensers designed to handle adhesive tapes. Some examples of tape dispensers include desktop dispensers, which may, for example, be used in office settings for ease of access. In some examples, industrial tapedispensers may handle larger rolls and heavier materials for commercial applications. Handheld tape dispensers may, for example, offer portability and ease of use in various settings. Desktop taping stations may, for example, offer stability and convenience for tasks that require frequent tape application in a stationary environment. In some embodiments, automatic tape dispensers may cut and dispense tape with minimal user input. Some examples may include packing tape dispensers, which may be used for sealing boxes and packages.

[0006] Handheld tape dispensers are available in various configurations to suit different user needs. Some examples of handheld tape dispensers include dispensers with integrated cutting mechanisms, which may, for example, facilitate efficient tape cutting. In some examples, dispensers with adjustable tension controls may allow for precise tape dispensing. Dispensers with refillable cartridges may, for example, enable easy tape replacement. In some embodiments, dispensers with built-in tape guides may provide accurate tape alignment during application. Some examples may include dispensers with ergonomic designs, which may enhance user comfort during extended use.

[0007] Handheld tape dispensers find applications across numerous fields due to their versatility and ease of use. Some examples of applications include packaging, where they may be used to seal boxes and parcels. In some examples, they may be used in construction for securing materials and marking surfaces. Handheld tape dispensers may, for example, be used in arts and crafts for creating and assembling projects. In some embodiments, they may be used in automotive repair for masking and securing components. Some examples may include medical settings, where they may be used for securing bandages and dressings. In some examples, they may be used in electrical work for insulating and bundling wires. Handheld tape dispensers may, for example, be used in retail for price tagging and packaging. In some embodiments, they may be used in education for classroom projects and displays. Some examples may include home improvement tasks, where they may be used for painting and repairs. In some examples, they may be used in event planning for decorating and securing materials.TECHNICAL FIELD

[0022] In order to assist rapid comprehension, this document introduces a handheld sheet goods applicator with a powered cutter directly driven by an adjacent actuator in Figs. 1-4. Cutting and dispensing modes of the cutter with respect to Figs. 5-6. The discussion turns to cutter direct drive embodiments with reference to Figs. 7-9. Finally, various additional embodiments and / or features are discussed related to powered-cutter sheet goods applicators.

[0023] Fig. 1 depicts an illustrative embodiment of a handheld sheet goods applicator with a selectively actuated cutter directly driven by a powered rotary actuator. For example, inIn a small wholesaler or home shop, an operator may be tasked with taping numerous packages daily. The operator may, for example, utilize a portable handheld applicator 1. The applicator 1 may be configured to reduce operator fatigue and improve cost efficiency. The applicator 1 may be gripped by a human hand using a handle 10. The operator may, for example, operate an activation input 16. The activation input 16 induces operation of a cutter actuator 82. The cutter actuator 82 may, for example, selectively operate a cutting element 88 between dispensing and cutting modes. This configuration may, for example, advantageously enable the tape to be severed without requiring a twisting motion of the wrist and / or arm. The powered operation may, for example, reduce fatigue or repetitive motion injury. The direct motor-to- cutter drive may, for example, advantageously reduce or eliminate the need for manual force and / or complex mechanical linkages. In some embodiments, the direct motor-to-cutter drive may, for example, reduce the overall component count within the applicator 1 and / or enable use of low-power and / or high-speed low-cost actuators (e.g., electric motors). A reduction in component count and / or cost may, for example, lead to decreased manufacturing costs. Lowerproduction costs may, for example, advantageously enable more users to benefit from safetyenhancing handheld applicators.

[0024] The cutting element 88 may be directly driven between a cutting and dispensing position (e.g., in a reciprocating linear motion) by a shaft body 84. The shaft body 84 may, for example, be a portion of a shaft 27 assembly, as shown in Fig. 4. The shaft body 84 may be rotated by the cutter actuator 82 (e.g., an electric motor) mounted adjacent to the cutter 100. This arrangement may enhance the efficiency and accuracy of the applicator 1. An applicator 1 may be configured as part of the applicator 1. The applicator 1 is connected to the handle 10. The handle 10 may be gripped by a human hand to facilitate operation and / or levitate the applicator 1 (e.g., during a dispensing and / or application operation). The handle 10 extends, in this example, from a body 12. The body 12 is coupled to a frame 7. The frame 7 supports various components (e.g., the cutter assembly).

[0025] Fig. 2 is an exploded view of the applicator illustrating the power storage and control modules. In this example, an embodiment configured as an electric handheld tape dispenser (applicator 1), such as shown in Fig. 1, includes a handle 10 and a body 12 mounted into and above the handle 10. The handle 10 is shaped like a shaft, suitable for hand gripping, and houses a power storage module 14 (e.g., a battery), as shown in Fig. 2. The handle 10 also includes an activation input 16 (e.g., a push button as shown). In some examples, the handle 10 may accommodate control module 15 (e.g., electronic circuit boards), switches, and / or electric motors. This configuration may enhance efficiency.

[0026] In some embodiments, the body 12 (e.g., configured as a frame) includes, as in this example, a roller 30, (e.g., a dispensing roller), a support roll 35, a cutter module 100, as shown in Fig. 4, control module 15 (e.g., electronic circuit board), and cutter actuator 82. The cutter actuator 82 may, for example, drive the roller 30 at a desired speed. The speed may, for example, be controlled by a speed controller on control module 15. The support roll 35 is mounted on a shaft and rotates about the shaft while supporting a roll of sheet goods such as adhesive tape (not shown).

[0027] The body 12 may be designed in various designs, sizes, and shapes. The handle 10 may be positioned anywhere on the tape dispenser and may vary in design, size, and shape. In some embodiments, the body 12 may be configured in a cylindrical shape. This configuration may, for example, facilitate ease of handling and storage.

[0028] In some embodiments, the body 12 may be designed in a rectangular form. Rectangular bodies may, for example, provide a stable base when the tape dispenser is placed on a flatsurface. In some embodiments, the body 12 may include a tapered design. Tapered bodies may, for example, enhance the ergonomic grip for the user.

[0029] In some embodiments, the handle 10 may be positioned on the top of the tape dispenser. This positioning may, for example, allow for a more natural wrist alignment during use. In some embodiments, the handle 10 may be located on the side of the tape dispenser. Side- positioned handles may, for example, provide better control during the application of tape. In some embodiments, the handle 10 may be integrated into the body 12 as a loop. Loop handles may, for example, offer a secure grip and reduce the risk of slippage. In some embodiments, the handle 10 may be designed as a pistol grip. Pistol grip handles may, for example, improve comfort and reduce hand fatigue during extended use. In various embodiments, the handle 10 may be configured as a knob. Knob handles may, for example, allow for quick and easy adjustments of the tape dispenser's position.

[0030] The roller 30, as shown in the example in Fig. 1, guides the rollout of the tape (not shown) and presses it onto a surface as it is dispensed. The roller 30 guides the tape smoothly from the support roll 35 to the cutting edge, for example, of the cutting element 88. This roller 30 may, for example, constrain the sheet goods to exit the applicator 1 during application in a consistent and straight path. Constraining the sheet goods in this manner may, for example, result in a more precise application. The roller 30 may, for example, apply pressure to adhere tape firmly to a surface being taped. Applying pressure in this manner may, for example, enhance the adhesion of the tape to the surface. The roller 30 may, for example, maintain appropriate tension on the tape to prevent slackening and / or pulling too tightly. Maintaining appropriate tension may, for example, prevent wrinkles or bubbles in the tape as it is applied. The roller 30 facilitates efficient and clean cutting by positioning the tape correctly for the cutting mechanism. Positioning the tape correctly may, for example, enhance usability by providing a point of contact for the user to pull the tape, making the dispensing process easier and more ergonomic.

[0031] Fig. 3 is an exploded view of an applicator embodiment provided with a powered dispensing roller. The roller 30, in this example, is a hollow cylindrical drum with one open end. One end of the roller 30 is connected to a frame 7, which is further connected to the cutter module 100 by fasteners such as bolts and screws via holes like hole 22 and secured in the threaded hole 23 and / or similar nearby holes. The roller actuator 60 is securely positioned using roller actuator mount 58. In some examples, where the roller actuator 60 is directly connected to the body 12, roller actuator mount 58 may be omitted.

[0032] The drum component includes the roller 30, a protective casing 28, and a roller actuator 60. In this example, the roller actuator 60 is encased by the protective casing 28. The protective casing 28 is, in turn, surrounded by the roller 30. In this example, the protective casing 28 is a hollow cylindrical drum. The protective casing 28 holds the cutter actuator 82, which may, for example, be an electric motor, in position. The protective casing 28 protects the roller actuator 60 against dirt and moisture. The protective casing 28 is connected to the cutter actuator 82 via fasteners such as bolts and screws. These fasteners are inserted through holes in the protective casing 28, such as hole 29. In the depicted example, the fasteners are secured in the threaded hole 61 of the roller actuator 60.

[0033] The shaft 27 of the roller actuator 60 passes through hole 41 of the protective casing 28. The shaft 27 also passes through hole 42 of the roller 30. Hole 42 may have a shape complementary to the shape of shaft 27. This configuration may create an interlocking fit. Shaft 27 then passes through the roller 30 via washer 40. The shaft 27 rests in hole 43 of frame 7. When the roller actuator 60 is energized, it drives the roller 30. In some examples, the roller actuator 60 may be directly encased by the roller 30. This configuration may allow the roller 30 to be driven by the cutter actuator 82 without the need for the protective casing 28.

[0034] Fig. 4 is an exploded view of the cutter assembly in an embodiment provided with a cutter cartridge. Fig. 4 depicts cutter module 100, which includes a cutting element 88, a guide rail body 87, a cutter actuator 82, and a shaft body 84, all positioned and secured on mount 81. The cutter actuator 82 may be energized to rotate its motor shaft. The rotation of the motor shaft may, for example, control the movement of the cutting element 88.

[0035] The shaft body 84 is a circular disc in this example. The shaft body 84 may include a shaft protrusion 85. The shaft protrusion 85 may engage with shaft engagement feature 92 of the cutting element 88. The cutting element 88 may, for example, be a blade. The cutting element 88 may be part of a cutter cartridge 86, as shown. The cutter cartridge 86 may include a cutter element holder 90. The cutter element holder 90 may, for example, be an aperture (e.g., into a cavity), as shown. For example, as depicted, the cutter element holder 90 may be a slot. The cutter element holder 90 may constrain and / or guide the cutting element 88, as shown.

[0036] The guide rail body 87 may include cutter rails 80 on both sides. The cutter rails 80 may interact with the cutting element 88. This system may provide a precise path for the cutting element 88 to follow. The precise path may, for example, advantageously facilitate smooth and controlled reciprocal movement.

[0037] During the taping process, the user may place applicator 1 on the surface of an object such as a carton box. The user may engage the activation input 16 located on the shaft of thehandle. Activation input 16 may connect to a control module, forming a closed circuit powered by power storage module 14 (e.g., a battery, such as a rechargeable battery). This may activate cutter actuator 82. The cutter actuator 82 may rotate its shaft 27 to drive the roller 30. The roller 30 may pull the tape from support roll 35. The applicator 1 may move in the direction guided by the user. The activation input 16 may be optimally placed along handle 10 for easy activation and deactivation by the user's finger. Control module 15 may function as an intermediary. The control module 15 may ensure seamless synchronization between the taping and cutting operations. For example, during the taping process, the circuit controller on control module 15 may prevent the tape from being cut abruptly while taping is in operation. In some embodiments, activation input 16, control module 15, and / or power storage module 14 may be placed anywhere on the applicator without necessarily having to be placed along the handle.

[0038] When the desired length of tape is dispensed, the tape may be cut off by a cutting mechanism. The cutting mechanism may vary in design, material, size, and operation method as long as it fits the applicator 1 and performs the cutting operation. The user may place the tape under the cutter and push the handle of the applicator toward the taping surface to cut the tape manually. The manually operated cutter may be replaced by a powered cutter. The powered cutting mechanism may be actuated by actuator input 97 (e.g., a trigger, as shown) located on the handle shaft. Once triggered, the cutting process may activate, causing cutter actuator 82 to drive the cutter component. The actuator coupler 83 may rotate the shaft body 84. The shaft protrusion 85 of the shaft body 84 may move within the shaft engagement feature 92 of the cutting element 88. The cutting element 88 may typically have an elongated slot fitting over shaft protrusion 85 on the motor's cam drive mechanism. As the motor rotates, the shaft protrusion 85 may move within shaft engagement feature 92, causing the blade to reciprocate. The optional cutter roller 96 may be useful for creating tension on the tape. The tension may facilitate the cutting process.

[0039] Figs. 5 and 6 depict this mechanism. Fig. 5 shows a bottom view (5 A) and a side view (5B) of the cutter assembly shown in Fig. 4 in a dispensing mode. Fig. 6 shows a bottom view (6A) and a side view (6B) of the cutter assembly shown in Figs. 4-5 in a cutting mode. In Fig. 5, shaft protrusion 85 of the shaft body 84 positions the cutter cartridge 86 in its initial position, starting at 0 degrees. The shaft protrusion 85 may, for example, be configured to operate as a rotating cam. In Fig. 6, when the cutter actuator 82 is energized, the shaft protrusion 85 moves clockwise from 0 degrees to 180 degrees. During this rotation, the cutter cartridge 86 gradually extends outward. The cutter cartridge 86 reaches full extension at 180 degrees. As the shaft continues to rotate from 180 degrees back to 0 degrees, the cutter cartridge 86 retracts. Thisfinishes the full cycle of extension and retraction. This reciprocating motion causes the cutter element to move in and out continuously. The continuous movement of the cutter element may, for example, achieve the cutting of tape during the cutting process. The cam may, for example, pull the blade back. The biasing member 89 (e.g., compression spring, extension spring) may help distribute the load more evenly across the entire system. This distribution of load may reduce the stress on individual components, such as the cam and motor. Reducing stress on these components may potentially increase their longevity.

[0040] Fig. 7 shows a schematic representation of a cutter mechanism, such as for a portable handheld tape dispenser. Fig. 7 is a schematic diagram depicting an embodiment having a linear actuator. The cutter actuator 82 is depicted on the right side of the figure. The cutter actuator 82 is configured to drive the cutter module 100.

[0041] The shaft protrusion 85 extends from the cutter actuator 82. The shaft protrusion 85 is operatively connected to the cutter module 100. The cutter module 100 is positioned on the left side of the figure.

[0042] The cutter module 100 is configured to move in a reciprocating linear motion, as indicated by the double-headed arrow. This motion is facilitated by the interaction between the cutter actuator 82 and the shaft protrusion 85. For example, the cutter actuator 82 may be a linear actuator. The cutter actuator 82 may, for example, push and / or pull the cutting element 88. The configuration may, for example, enable efficient cutting of tape by directly translating the motion from the cutter actuator 82 to the cutter module 100.

[0043] Fig. 8 shows a configuration of components, such as for a portable handheld tape dispenser. Fig. 8 is a schematic diagram depicting an embodiment with a distal cam surface arranged in line with the reciprocating motion path. The cutter actuator 82 is depicted on the right side of the figure. The cutter actuator 82 is operatively connected to rotate the shaft 27. The shaft 27 is operably coupled to a shaft body 84. The shaft body 84 is positioned to reciprocally drive the cutting element 88 between the cutting and dispensing positions. For example, the shaft body 84 may have a cam surface at the end configured to vary a linear displacement of the cutting element 88. The biasing member 89 is depicted as being connected to the cutting element 88. The biasing member 89 may provide a force to return the cutting element 88 to its original position after cutting.

[0044] Fig. 9 is a schematic diagram depicting an embodiment with a distal cam surface arranged intersecting the reciprocating motion path. The cutter actuator 82 is depicted as a circular element, which may, for example, facilitate the movement of the cutting mechanism. This configuration may enhance the efficiency of the cutting process.

[0045] The shaft protrusion 85 is shown extending from the cutter actuator 82 (e.g., into the cutter actuator 82). The cam 102 is illustrated adjacent to the shaft protrusion 85. The cam 102 may, for example, convert rotary motion into linear motion, which can be advantageous for driving the cutting element 88. For example, the cam 102 may be configured as the terminating surface of the shaft protrusion 85. The cutter actuator 82 may be directly coupled to the shaft, which may be directly coupled to the cutter protrusion 104 of the cutter assembly.

[0046] The cutter protrusion 104 is depicted as a vertical extension from the cutting element 88. The cutter protrusion 104 may, for example, engage with the cam 102 such that the cutting element 88 is selectively translated between a cutting and dispensing position. For example, a biasing member (not shown) may urge the cutting element 88 to a 'default' position (e.g., dispensing mode).

[0047] Although various embodiments are shown and described, other embodiments are contemplated.

[0048] In some embodiments the activation input 16 may, for example, be configured as a sensor (e.g., touchless) to activate and / or deactivate the applicator 1. The taping process may, for example, be actuated by the function mode managed by a circuit controller of the control module 15 of applicator 1. The circuit controller may, for example, oversee processes using sensors, a microcontroller, and / or actuators. For example, a product detection sensor may identify the presence of a product, prompting the dispensing motor to start.

[0049] In some embodiments, cutter actuator 82 can be placed at any convenient location away from the position indicated in Fig. 4. For example, the cutter actuator 82 may be aligned axially with the blade as shown. In some embodiments, it may be placed at any angle and / or location, such as a horizontal position. In this case, components such as gears, rods, or linkages may be used to connect the cutter motor to the shaft. For instance, the cutter motor shaft can connect to a gear or gear set, which then interacts with the gear of the cam to rotate it, causing the blade to reciprocate. The cutter motor can be positioned anywhere within the tape dispenser by utilizing gear sets, connectors, linkages, and other mechanisms to drive the cam, which controls the movement of the blade component.

[0050] In some embodiments, the cutting element 88 may, for example, be a blade itself without a blade holder. The shaft engagement feature 92 may, for example, be part of the blade itself. This configuration may, for example, simplify the design. Manufacturing costs may, for example, be reduced with this design.

[0051] The applicator 1 may, for example, advantageously be configured such that tape dispensing is manually powered by human strength without assistance from a motor, while thecutting mechanism is electrically powered. In this design, the roller 30 may, for example, function as a freely rotating guide roller that facilitates the tape feeding out evenly and / or preventing it from sticking to itself and / or twisting. The roller may, for example, rotate without being powered (e.g., by an electric motor). Such embodiments may, for example, reduce or eliminate the need for the corresponding motor and its related components. When it's time to cut the tape, the user may, for example, press actuator input 97 and / or other operator interface (e.g., a lever) to activate the electric cutter. Various embodiments of the cutter may, for example, operate with or without the aid of a circuit controller on control module 15, providing flexibility in the design and functionality of the tape dispenser. This setup may, for example, allow for efficient manual tape dispensing while facilitating precise and effortless cutting through the electrically powered mechanism.

[0052] In some embodiments, actuator input 97 can be omitted and replaced by a sensor to activate or deactivate the powered cutter. The actuator input 97 may, for example, be configured to work in combination with a sensor to provide enhanced control and responsiveness.

[0053] The cutting mechanism can be actuated by the cutting function mode managed by the circuit controller. The circuit controller manages the cutting process through sensors, a microcontroller, and actuators. For instance, a sensor monitors the dispensed tape, and the microcontroller stops the dispensing motor once the desired tape length is reached. The microcontroller signals the cutting mechanism's actuator, ensuring the blade is correctly positioned via a position sensor. The actuator drives the blade to cut the tape, confirmed by the position sensor, and then resets the cutting mechanism for the next cycle. The control logic in the microcontroller's firmware handles different operational states, making real-time decisions based on sensor inputs for precise and efficient tape dispensing and cutting.

[0054] Some embodiments may include various cutting mechanisms. A powered scissor cutting mechanism may, for example, be implemented in the applicator 1. This mechanism may include a fixed blade and a movable blade positioned to form a shearing interface for cutting tape. As the tape is dispensed, it may, for example, be guided toward the cutting area by guide rollers. Guide rollers may facilitate an even feed and proper alignment. The cutting mechanism may be activated when the user presses a button or lever. This action may send a signal to an electric motor managed by a circuit controller. The motor may drive the movable blade against the fixed blade, creating a shearing force that cuts through the tape.

[0055] In some examples, an electric motor may rotate to drive a cam, gear, or linkage mechanism connected to the movable blade. This may convert rotational motion into linearmotion. Once the tape is cut, the circuit controller may facilitate the return of the movable blade to its original position. This may be achieved through motor reversal and / or a spring mechanism (e.g., biasing member 89), preparing the dispenser for the next use.

[0056] In various embodiments, sensors and / or switches may be incorporated to detect the tape's position. These components may facilitate correct alignment before cutting and enhance precision. This powered scissor cutting mechanism may facilitate efficient, precise, and reliable tape cutting with minimal manual effort. Such mechanisms may be particularly beneficial in high-volume tape dispensing environments.

[0057] A powered needle mechanism may, for example, augment and / or replace the single blade cutting mechanism in applicator 1. In some examples, the cutter module 100 may facilitate efficient and precise puncturing or poking of holes in the tape. The cutter module 100 may, for example, include a needle assembly. The needle assembly may, for example, include a sharp, pointed needle. In some embodiments, the needle may be attached to an actuator. The actuator may, for example, include an electric motor. Guide rollers may, for example, dispense and guide the tape to the needle assembly area. The guide rollers may facilitate an even feed and proper alignment.

[0058] When the user initiates the needle mechanism by pressing a button or lever, a signal may, for example, be sent to the electric motor. In some examples, the electric motor may, for example, be managed by a circuit controller (e.g., control module 15). The motor may, for example, drive the needle downward to puncture the tape. This configuration may facilitate creating a hole with precision and minimal manual effort. After the needle punctures the tape, the circuit controller may, for example, signal the actuator to retract the needle to its original position. This may, for example, ready the dispenser for the next operation.

[0059] In some embodiments, sensors and / or switches may, for example, be incorporated to detect the tape's position. Detecting the tape's position may, for example, facilitate correct alignment before the needle punctures the tape. Correct alignment may, for example, enhance precision and reliability. This powered needle mechanism may, for example, be advantageous in applications requiring consistent tape puncturing. Consistent tape puncturing may, for example, provide efficient operation. Efficient operation may, for example, reduce the physical effort needed from the user.

[0060] This design may, for example, facilitate the use of the tape dispenser in a variety of settings. Some examples of such settings may include packaging, labeling, or other industrial uses.

[0064] In some embodiments, the sheet goods roll may, for example, be mounted directly on the roller 30. The adapter may, for example, be omitted in embodiments configured to attach a roll of tape directly to the roller 30. During the taping process, the electric motor may activate and rotate the roller. This may facilitate the release of the tape onto the surface of the object. The tape may then be cut by the powered cutting mechanism as previously described. This configuration may be useful in applications where the tape does not need to touch the surface of the object. In such cases, the dispensing roller may act as the adapter. Its size and shape may vary, for example, as long as it accommodates the tape or a roll of shrink wrap.

[0065] Various embodiments of the disclosed applicator may address challenges associated with manual tape dispensers by reducing operator fatigue and discomfort.

This feature may enhance user control and precision during the cutting process.

[0068] In some embodiments, the applicator may be designed to be compact and lightweight, enhancing portability and accessibility. For example, the use of separate motor systems for the tape feed and cutting mechanism may optimize power requirements for each function, resulting in efficient performance.

This configuration may provide indexed and / or angular control of the cutting process. The blade may be housed in a rigid frame. Axial support may, for example, be provided via ball bearings or bushings. Theblade may, for example, be partially recessed within a protective shroud.
