Description

Technical Field

[0001] This invention relates to the field of stationery products, and more particularly to an attention training system, a sticker dispensing device, and a control method. Background Technology

[0002] Many children enjoy playing with stickers, sticking them on their toys and backpacks. Playing with stickers can distract children and, in turn, cultivate their fine motor skills and initiative in learning. Stickers are typically produced by attaching printed material coated with adhesive to a vinyl-coated release liner or release film (i.e., backing paper). To use them, the adhesive is separated from the release liner and then applied to the desired product or item.

[0003] Existing technologies offer various solutions for peeling stickers from the backing paper. Existing technologies, such as Chinese Utility Model Patent (Publication No.: CN2280699Y) and US Patent (Publication No.: US5770008A), disclose a press-type sticker dispenser. This dispenser manually drives a friction wheel via a pressing rack, and the friction wheel moves a strip of paper to dispense the sticker through friction. However, the sticker separation in these existing technologies is all manual, resulting in poor ease of use. Furthermore, existing sticker dispensers require replacing the entire frame along with the sticker, which is wasteful and increases the cost of use for consumers.

[0004] To address the aforementioned technical problems, the applicant has further applied for a sticker dispensing device, comprising a main body and a sticker box. The sticker box is detachably fitted to the main body and is used to hold cylindrical stickers. The sticker dispensing device is equipped with a winding shaft for winding a backing paper after the stickers have been peeled off. The winding shaft is driven by a drive mechanism, causing the backing paper to move and wind around the winding shaft. During this process, the backing paper is in a taut state. When all the stickers on the backing paper have been peeled off, or when the user wants to replace the sticker box for other reasons, the user can remove the sticker box and replace the stickers. Because the backing paper is always in a taut state, when it is necessary to remove the sticker box from the main body, the winding shaft is not easily disengaged from the drive mechanism due to the tension of the backing paper, making it difficult to remove the sticker box.

[0005] To further address the aforementioned technical issues, improve patent portfolio, and build effective patent barriers, this application is hereby submitted. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a sticker dispensing device to solve the problem of difficulty in removing the sticker box in the existing sticker dispensing device.

[0007] To achieve the above objectives, the present invention employs the following technical solution: a sticker dispensing device, wherein the sticker is peelably adhered to a backing paper; comprising: a body on which a motor capable of outputting rotational power is mounted; and a sticker box having a winding shaft for winding the backing paper after the sticker has been peeled off; wherein the sticker box is detachably coupled to the body, and the winding shaft and the motor are connected via a detachable coupling structure; wherein the winding shaft is configured to be driven by the motor to rotate forward and reverse, and after the winding shaft rotates forward to tighten the backing paper and peel off at least one sticker, the winding shaft is controlled to reverse by a set angle to loosen the backing paper so that the coupling structure can be easily separated.

[0008] Preferably, the coupling structure includes a shaft portion and a hole portion that drivesly engages with the shaft portion, one of which is disposed on the body and the other is disposed on the sticker box.

[0009] Preferably, the body has an output shaft that is drive-connected to the motor, and the shaft portion is formed on the output shaft.

[0010] Preferably, the shaft portion has a plurality of toothed portions evenly distributed along its outer periphery.

[0011] Preferably, the hole is formed on the winding shaft.

[0012] Preferably, the hole has a plurality of toothed portions evenly distributed along its inner circumference.

[0013] Preferably, after the forward rotation stops, the liner paper tightens, resulting in a tight fit between the shaft and the hole; after the reverse rotation stops, the liner paper loosens, resulting in a loose fit between the shaft and the hole. Reversing the rotation eliminates the tension exerted by the liner paper on the winding shaft, and with the shaft and hole in a loose fit, the sticker box can be easily separated from the main body.

[0014] Preferably, a cavity is formed on the body, and the sticker box is received in the cavity.

[0015] Preferably, the body has a locking mechanism that can lock the sticker box onto the body.

[0016] Preferably, the main body is provided with an operating part, which can operably release the locked state of the sticker box.

[0017] This application also provides a control method for a sticker dispensing device, wherein the sticker is peelably adhered to a backing paper; the sticker dispensing device includes a body and a sticker box detachably coupled to the body, the body having a motor capable of outputting rotational power, the sticker box having a winding shaft for winding the backing paper, and the motor and the winding shaft being drively connected via a detachable coupling structure; in the control method of the sticker dispensing device, the following processing is performed by a control circuit: controlling the motor to rotate forward, so that the backing paper is tightened and at least one sticker is dispensed; then controlling the motor to rotate in reverse, so that the backing paper is loosened so that the coupling structure can be easily separated.

[0018] Preferably, after the forward rotation stops, the liner paper is tightened so that the coupling structure is in a tight fit; after the reverse rotation stops, the liner paper is loosened so that the coupling structure is in a loose fit.

[0019] Preferably, after outputting a sticker, the motor is controlled to reverse to loosen the backing paper.

[0020] Preferably, the coupling structure includes a shaft portion and a hole portion that drivesly engages with the shaft portion, one of which is disposed on the body and the other is disposed on the sticker box.

[0021] This application also provides an attention training system having the sticker dispensing device described in any of the preceding claims, wherein after a trainee completes a set attention training task, the sticker dispensing device operably outputs at least one sticker to reward the trainee.

[0022] Due to the adoption of the above technical solutions, the present invention has the following beneficial effects: the sticker dispensing device of the present invention has a winding shaft that can be driven to rotate forward and reverse. When it rotates forward, it can drive the backing paper to move forward so as to peel off the sticker normally. When it rotates in reverse, it can loosen the backing paper to release the sticker tension from the winding shaft, thereby facilitating the separation of the sticker box from the body.

[0039] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0040] This embodiment provides a user-friendly sticker machine with a built-in sticker roll formed by peeling sticker P2 onto backing paper P1 and then winding it. It includes a body 1 and a sticker box 2. The body 1 has a motor 3A capable of outputting rotational power, and the sticker box 2 has a backing paper roll 2B for winding the backing paper after the stickers have been peeled off. The sticker box 2 is detachably connected to the body 1 for easy replacement, and the backing paper roll 2B and the motor 3A are connected via a separable coupling structure 4. The backing paper roll 2B is configured to be driven by the motor 3A to rotate forward and reverse. After the forward rotation of the backing paper roll 2B tensions the backing paper P1 and peels off at least one sticker P2, the controlled reverse rotation of the backing paper roll 2B relaxes the backing paper P1, making the coupling structure 4 easy to separate.

[0041] The sticker-applying machine of this application is capable of peeling sticker P2 off the backing paper P1. Combined with Figure 2 Figure 10 It includes a body 1, a sticker box 2, a drive mechanism 3, a coupling structure 4, a locking mechanism 5, a pusher 6, a first elastic element 7, a pressing element 8, a battery element 9, a horn element 10, a handle element 11, a first circuit element 12, a second circuit element 13, a detection mechanism 14, and a second elastic element 15. Further explanation follows.

[0042] [Main Body] The main body 1 includes a first housing 1A, a second housing 1B, a third housing 1C, and a cover 1D. The third housing 1C is installed between the first housing 1A and the second housing 1B. The second housing 1B has a cavity S for accommodating the sticker box 2. The cover 1D is movable relative to the second housing 1B to cover the cavity S. Figure 2 The main body 1 has a paper output slot Q. The first housing 1A is equipped with control buttons and a display screen.

[0043] [Sticker Box] The sticker box 2 has a body 2A and a winding shaft 2B. The dimensions of the body 2A are adapted to the dimensions of the cavity S, allowing the sticker box 2 to be received within the cavity S. The body 2A has a mounting portion for mounting the tubular backing paper P1. The winding shaft 2B is rotatably mounted within the body 2A, combined with... Figure 8 The winding shaft 2B is used to wind the backing paper P1 after the sticker P2 has been peeled off. Combined Figure 8 The sticker box 2 and the main body 1 are detachably coupled. The main body 2A has a receiving groove 2C corresponding to the position of the motor 3A. Figure 11 The main body 2A has a sticker compartment 2D for accommodating the sticker roll P and a deflecting peeling part 2E. The deflecting peeling part 2E can peel the sticker P2 off the backing paper P1 by conveying the backing paper P1 in a direction different from the traveling direction of the sticker P2. The deflecting peeling part 2E is located at the paper outlet T and protrudes slightly from the paper outlet T. When viewed in the assembly direction from the sticker box 2 to the main body 1 (see reference...), Figure 11 The peeling section 2E is tilted upwards and to the left to tension the backing paper P1. Figure 11The sticker box 2 has a conveying resistance increasing section 2F located upstream of the paper outlet T on the conveying path of the backing paper P1. The conveying resistance increasing section 2F is configured to increase the conveying resistance of the backing paper P1, so that the backing paper P1 is in a taut state when peeling off the sticker P2. When the backing paper P1 is taut, the sticker P2 is easier to peel off. The conveying resistance increasing section 2F includes at least one protrusion (multiple protrusions in this embodiment) that protrudes towards the backing paper P1 to press against it, thus increasing the conveying resistance of the backing paper P1. In this embodiment, the conveying resistance increasing section 2F is an uneven surface formed on the outer wall of the body 2A. The conveying resistance increasing section 2F increases the conveying resistance of the backing paper P1 by pressing against it or increasing the frictional force in contact with the backing paper P1. When the conveying resistance increases, the backing paper P1 is in a taut state, especially at the paper outlet T, the tighter the backing paper P1 is pulled, the easier it is to peel off the sticker. Figure 11 The sticker box 2 has a paper conveying path for conveying the backing paper P1, including a feeding channel 2G and a receiving channel 2H. A sticker P2 is attached to the backing paper P1 in the feeding channel 2G, while the sticker P2 has been peeled off the backing paper P1 in the receiving channel 2H. The paper conveying path is configured to slope upwards from its upstream end to the paper outlet T, so that the backing paper P1 is in a taut state when peeling off the sticker P2. The deflecting peeling section 2E is configured to slope upwards to the left. The turning angle formed by the backing paper P1 at the deflecting peeling section 2E is greater than 90°. The upward slope of the paper conveying path at the paper outlet T and the upward slope of the deflecting peeling section 2E are all designed to make the sticker P2 easier to peel off, thereby preventing it from sticking to the sticker box 2.

[0044] [Drive Mechanism] Drive mechanism 3 is used to drive the winding shaft 2B to rotate, so that the backing paper P1 is gradually wound onto the winding shaft 2B. For example... Figure 4 The drive mechanism 3 includes a motor 3A, a gear transmission assembly 3B, and an output shaft 3C. The motor 3A is mounted on the main body 1, located between the second housing 1B and the third housing 1C, and is capable of outputting rotational power. The gear transmission assembly 3B is mounted on the third housing 1C and is used to drive the motor 3A and the output shaft 3C, so that the motor 3A can drive the output shaft 3C to rotate via the gear transmission assembly 3B. In other embodiments, the drive mechanism 3 may also consist of the motor 3A and other transmission mechanisms, or it may not have a transmission mechanism; the output shaft 3C is the output shaft of the motor 3A. Furthermore, it should be noted that the transmission connection between the winding shaft 2B and the motor 3A via the separable coupling structure 4 means that they can be directly connected via the coupling structure 4, or a transmission mechanism can be installed between them, and then the transmission connection can be achieved through the coupling structure. In other words, the aforementioned transmission connection includes both direct and indirect transmission connections between the winding shaft and the motor.

[0045] [Coupling Structure] Coupling structure 4 is a detachable coupling structure, through which the winding shaft 2B and the motor 3A are connected. Figure 9 and Figure 10 The coupling structure 4 includes a shaft portion 4A and a hole portion 4B that drives and engages with the shaft portion 4A. In this embodiment, the shaft portion 4A is disposed on the body 1. Specifically, the shaft portion 4A is formed on the output shaft 3C, thereby indirectly disposed on the body 1. The shaft portion 4A and the output shaft 3C have a mating spline structure. In other embodiments, it can also be a gear structure or other separable connection structure. In this embodiment, the hole portion 4B is disposed on the sticker box 2. Specifically, the hole portion 4B is formed on the winding shaft 2B. The positions of the shaft portion 4A and the hole portion 4B can also be interchanged. The motor 3A drives the output shaft 3C to rotate through the gear transmission assembly 3B, and the output shaft 3C drives the winding shaft 2B to rotate through the separable coupling structure 4. By controlling the rotation direction of the motor 3A, the winding shaft 2B can be driven to rotate forward and backward. The outer periphery of the shaft portion 4A and the inner periphery of the hole portion P2 are adapted to each other. In one embodiment, the shaft portion 4A may have a plurality of toothed portions evenly distributed along its outer periphery, and the hole portion 4B may have a plurality of toothed portions evenly distributed along its inner periphery. The sticker dispensing device of this application is configured such that: after the winding shaft 2B rotates forward to tension the backing paper P1 and peel off at least one sticker P2, the winding shaft 2B is controlled to rotate in reverse to relax the backing paper P1 so that the coupling structure 4 can be easily separated. After the winding shaft 2B stops rotating forward, the backing paper P1 is tensioned, resulting in a tight fit between the shaft portion 4A and the hole portion 4B; after the winding shaft 2B stops rotating in reverse, the backing paper P1 is relaxed, resulting in a loose fit between the shaft portion 4A and the hole portion 4B. Specifically, motor 3A drives winding shaft 2B to reverse by a set angle, a set number of revolutions, or a set time to loosen the backing paper P1. However, the winding shaft 2B should not be allowed to rotate excessively, causing excessive loosening of the backing paper P1. In practice, for motors that are difficult to control precisely, the reversal time of the motor can be set, such as 1 second or 0.5 seconds, and then converted to the reversal angle of winding shaft 2B through the transmission ratio. For motors that can be controlled precisely, the rotation angle or number of revolutions of winding shaft 3B can be directly set, such as reversing 90° or reversing 1 revolution, and then converted to the number of reversal revolutions of motor 3A through the transmission ratio of the transmission mechanism. In addition, the controlled reversal of winding shaft 2B means that the reversal is generated under the drive of the motor. The motor is controlled by the control circuit. When reversing, the control circuit sends a reversal signal and a drive signal, thereby causing the motor to reverse. As mentioned above, the reversal of the motor is controlled by the control circuit, which in turn drives the winding shaft to reverse. Therefore, the reversal of the winding shaft is controlled, rather than an uncontrolled free reversal.

[0046] It should be emphasized that, in this application, after the winding shaft 2B rotates forward to tension the liner P1 and peel off at least one sticker P2, the winding shaft 2B is controlled to rotate in reverse to relax the liner P1 so that the coupling structure 4 can be easily separated.

[0047] [Locking Structure] The locking mechanism 5 is located on the main body 1 and can lock the sticker box 2 onto the main body 1. In this embodiment, the locking mechanism 5 is slidably engaged with the third housing 1C. Figure 9 A second elastic element 15 is provided between the locking mechanism 5 and the second housing 1B. Figure 8 When the locking mechanism 5 slides relative to the body 1 under the action of an external force, the locking mechanism 5 releases the lock on the sticker box 2. At this time, the second elastic element 15 elastically contracts. When the second elastic element 15 elastically returns to its original position, it can push the locking mechanism 5 to reset. Figure 8 In this embodiment, after opening the cover 1D, the user can manually push the locking mechanism 5 upwards ( Figure 8 (From a certain perspective), this allows the sticker box 2 to be installed in or detached from the recess S. It should be understood that, in another embodiment, an operating part may be configured on the body 1, the operating part being drively connected to the locking mechanism 5 to control the sliding of the locking mechanism 5 relative to the body 1, that is, the operating part can operably release the locked state of the sticker box 2.

[0048] [Assistive Structure] The pushing component 6 and the first elastic component 7 cooperate to form an assistive structure, which is used to assist in pushing the sticker box 2 out of the cavity S. Specifically, combined with Figure 4 The first elastic element 7 is constrained between the pusher 6 and the third housing 1C. The pusher 6 has an end that extends into the recess S. When the sticker box 2 is installed in the recess S, the pusher 6 is pushed by the sticker box 2 to elastically contract the first elastic element 7. When the locking mechanism 5 is subjected to external force and slides relative to the body 1 to allow the sticker box 2 to disengage, the first elastic element 7 elastically resets, thereby assisting in pushing the sticker box 2 out of the recess S.

[0049] Pressing element 8 is mounted on the main body 1. Pressing element 8 controls the operation of motor 3A. When the user presses pressing element 8, motor 3A controls the winding shaft 2B to rotate forward, tensioning the backing paper P1, and peeling off a sticker P2, which is then output from the paper outlet Q. Battery element 9 is mounted on the main body 1 to provide power for the sticker dispensing device. Speaker element 10 is mounted on the main body 1 to play operating information of the sticker dispensing device. Handle element 11 is mounted on the main body 1 for the user to grip. First circuit element 12 and second circuit element 13 are mounted on the main body 1 to control the operating status of the sticker dispensing device, wherein the first circuit element 12 has a power switch. Pressing element 8 has a pressure-applying part 8A, and the first circuit element 12 has a pressure-receiving part 12A that cooperates with the pressure-applying part 8A. When the pressure-applying part 8A applies pressure to the pressure-receiving part 12A, the pressure-receiving part 12A generates an electrical signal so that the control circuit controls the operation of motor 3A.

[0050] Testing agency 14 is used to check whether sticker box 2 is installed correctly. Specifically, in conjunction with Figure 8 and Figure 9 The detection mechanism 14 includes a trigger 14A and a sensor 14B (a microswitch in this embodiment). The trigger 14A is slidably engaged with the body 1 and has an end that extends into the cavity S. The sensor 14B is integrated on the first circuit component 12. When the sticker box 2 is installed in the cavity S, the trigger 14A is pushed to extend into the cavity S, causing the trigger 14A to slide and trigger the sensor 14B, thereby detecting that the sticker box 2 is installed in place by the first circuit component 12.

[0051] This application also provides a control method for the aforementioned sticker dispensing device. The sticker dispensing device performs the following processing via a control circuit: controlling motor 3A to rotate forward, causing the backing paper P1 to tighten and output at least one sticker P2; then controlling motor 3A to rotate in reverse, causing the backing paper P1 to loosen, making the coupling structure 4 easier to separate. After the winding shaft 2B stops rotating forward, the backing paper P1 is tightened, causing the coupling structure 4 to be in a tight-fitting state (at this time, the backing paper P1 applies tension to the winding shaft 2B circumferentially, making the winding shaft 2B difficult to separate); after the winding shaft 2B stops rotating in reverse, the backing paper P1 loosens, causing the coupling structure 4 to be in a loose-fitting state. After outputting one sticker P2, controlling motor 3A to rotate in reverse to loosen the backing paper P1. In a specific application, motor 3A can be rotated in reverse after each sticker P2 is separated. In another specific application, after all stickers P2 have been completely peeled off, motor 3A can be reversed. To detect that all stickers P2 have separated, a detection mark can be provided at the end of the backing paper P1, and the sticker dispensing device can be equipped with a detection element to detect the aforementioned mark. When the aforementioned detection mark is detected, it can be determined that all stickers P2 have separated. In another specific application, an operation button can be provided to control the cover 1D to open. At this time, the sticker dispensing device can control motor 3A to reverse according to the electrical signal generated by the operation button, so that the backing paper P1 is loosened.

[0052] This application also provides an attention training system having the aforementioned sticker dispensing device. After a trainee (such as a child) completes a set attention training task, the sticker dispensing device operably outputs at least one sticker P2 as a reward to the trainee. Specifically, after the trainee completes the set attention training task, they can tap the pressing member 8 to output the sticker P2 from the paper output port Q. The sticker dispensing device may integrate a timing function to facilitate the user completing the attention training task within a set time.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
