Currently, the labeling operation is performed manually. Staff need to hold the end of the label tape with one hand and the beginning of the new label roll with the other, then align the two together. This operation is cumbersome, and manual operation is slow, making rapid alignment impossible. Utility Model Content

[0028] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0029] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0030] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0031] refer to Figures 1 to 2An automatic label applicator according to a preferred embodiment of the present invention will be described in detail below. The automatic label applicator includes a main body 100 and a label feeding device 200. The main body 100 has a spare supply area and a production supply area, wherein the spare supply area is located above the production supply area. The label feeding device 200 includes a supply mechanism 210, which includes two supply components 211. The two supply components 211 are detachably disposed in the spare supply area and the production supply area, respectively. The supply component 211 located in the spare supply area is used to install spare label rolls, and the supply component 211 located in the production supply area is used to install working label rolls.

[0032] After the supply component 211 located in the production supply area is removed, the supply component 211 located in the spare supply area can be moved to the production supply area. At this time, the spare label roll installed on the corresponding supply component 211 is used for production. The supply component 211 removed from the production supply area is loaded with a new label roll and then installed in the spare supply area. The corresponding new label roll is used as a spare.

[0033] The supply mechanism 210 further includes a usage detection element 212, which is disposed in the production supply area of ​​the equipment body 100. The usage detection element 212 is used to detect the remaining quantity of work label rolls located in the production supply area and installed on the corresponding supply element 211. The usage detection element 212 is communicatively connected to a controller, and the controller is controlled by an alarm. The controller selectively controls the alarm to operate based on feedback from the usage detection element 212, so as to remind workers of the usage of work label rolls.

[0034] Preferably, the usage detection element 212 is implemented as a photoelectric sensor. When a supply unit 211 with a work label roll is installed in the production supply area, the photoelectric sensor is located close to the corresponding work label roll. When the signal radiated by the photoelectric sensor is blocked by the work label roll corresponding to the supply unit 211, the photoelectric sensor feeds back to the controller, and the controller controls the alarm to stop. As the work label roll located in the production supply area and installed on the corresponding supply unit 211 is continuously unwound, so that the signal radiated by the photoelectric sensor is not blocked, the photoelectric sensor feeds back to the controller, and the controller controls the alarm to activate, so as to prompt the staff that the corresponding supply unit 211 is empty, so that the staff can remove the corresponding supply unit 211 in time.

[0035] It is worth mentioning that after the supply component 211 located in the production supply area is removed, the supply component 211 located in the spare supply area can be driven down to the production supply area and used as a spare label roll for production.

[0036] Preferably, the supply mechanism 210 includes a switching component 213, which includes two mounting members 2131 and a driving assembly 2132. Each supply member 211 is detachably mounted to one of the mounting members 2131, and the mounting member 2131 is slidably mounted to the equipment body 100. Both mounting members 2131 are mounted to the driving assembly 2132 so that they are driven by the driving assembly 2132 to raise one to correspond to the standby supply area and lower the other to correspond to the production supply area.

[0037] Preferably, the driving assembly 2132 includes a belt, two turntables, and a motor. One of the turntables is mounted on the motor and driven to rotate by the motor. The two turntables are vertically spaced by a predetermined distance and are both connected by the belt. A mounting member 2131 is respectively mounted on the portion of the belt located on either side of the line connecting the axes of the two turntables. When the motor drives the corresponding turntable to rotate, and the corresponding turntable drives the other turntable to rotate via the belt drive, the belt causes one mounting member 2131 to move upward and the other mounting member 2131 to move downward.

[0038] refer to Figure 3 The switching component 213 further includes two triggers 2133, each of which is arbitrarily installed on one of the mounting components 2131 and one of the supply components 211. The triggers 2133 are used to detect the connection or disconnection between the supply component 211 and the mounting component 2131. The triggers 2133 are communicatively connected to the controller, and the drive assembly 2132 is controllably connected to the controller. The controller selectively controls the operation of the drive assembly 2132 based on feedback from the triggers 2133.

[0039] Preferably, the trigger 2133 is implemented as a pressure sensor. The supply component 211 is detachably inserted into the mounting component 2131, and the pressure sensor is positioned on the movement path of the supply component 211 as it is inserted into the mounting component 2131. When the two supply components 211 are respectively inserted into the two mounting components 2131, the two pressure sensors are respectively squeezed by the corresponding supply components 211 and feed back to the controller, causing the drive assembly 2132 of the controller to pause operation. After the worker removes the supply component 211 located in the production supply area, the corresponding pressure sensor is no longer compressed and feeds back to the controller, causing the controller to drive the drive assembly 2132 to move the mounting component 2131 with the corresponding pressure sensor upward and the other mounting component 2131 downward, thereby achieving a position switch.

[0040] Those skilled in the art will understand that the trigger 2133 can be implemented as any of a distance sensor, photoelectric sensor, proximity switch, etc., which will not be described here.

[0041] refer to Figure 1 as well as Figures 4 to 6 The label supply device 200 includes a label receiving mechanism 220, which includes a label receiving component 221. The label receiving component 221 includes a label receiving member 221 and a tape fixing component 2211. The tape fixing component 2211 includes a lower tape fixing group 22111 and an upper tape fixing group 22112. The lower tape fixing group 22111 is installed on the equipment body 100, and the lower tape fixing group 22111 and the upper tape fixing group 22112 are vertically spaced apart. A working label tape formed by unwinding a working label roll located in the production supply area and installed on the corresponding supply component 211 passes over the lower tape fixing group 22111. A spare label tape formed by unwinding a spare label roll located in the spare supply area and installed on the corresponding supply component 211 is fixed by the upper tape fixing group 22112 with its first end placed at the bottom of the upper tape fixing group 22112.

[0042] The label receiving component 221 includes a label detection element 2212. The label detection element 2212 can radiate a signal, and the direction of its radiated signal intersects the movement direction of the working label tape moving above the lower fixing tape group 22111. The label detection element 2212 is used to detect whether the working label tape has moved out of its signal radiation range. The label detection element 2212 is communicatively connected to the controller, and the controller is controllably connected to the lower fixing tape group 22111. The controller selectively controls the lower fixing tape group 22111 to fix the end of the working label tape above it based on the feedback from the label detection element 2212.

[0043] Specifically, when the label moves through the signal radiation range of the label detection element 2212, causing the label detection element 2212 to detect the working label tape, the label detection element 2212 sends feedback to the controller, and the controller controls the lower fixing tape group 22111 to stop operating. At this time, the working label tape is not fixed. When the working label tape moves so that its end moves through the signal radiation range of the label detection element 2212, causing the label detection element 2212 to not detect the working label tape, the label detection element 2212 sends feedback to the controller, and the controller controls the lower fixing tape group 22111 to fix the end of the working label tape.

[0044] Preferably, the lower fixing tape assembly 22111 includes a lower fixing tape body 221111 and a lower vacuum suction component 221112. The lower fixing tape body 221111 is installed on the device body 100. A plurality of spaced-apart lower suction holes 22111101 are formed on the upper surface of the lower fixing tape body 221111, communicating with its interior. The lower vacuum suction component 221112 communicates with the lower fixing tape body 221111. The working label tape moves above the lower suction holes 22111101. The lower vacuum suction component 221112 is connected to the controller and is configured to suction gas from the lower fixing tape body 221111 and adhere and fix the end of the working label tape through the lower suction holes 22111101. The signal radiated by the label detection element 2212 is located on the side of the lower suction hole 22111101 near the supply element 211.

[0045] Preferably, the lower vacuum suction component 221112 is implemented to include a vacuum pump.

[0046] The label receiving component 221 further includes a label receiving assembly 2213, which is installed on the upper fixing tape group 22112. Both the label receiving assembly 2213 and the upper fixing tape group 22112 are controllably connected to the controller. The controller selectively controls the label receiving assembly 2213 to perform the label receiving action based on feedback from the label detection component 2212 and selectively controls the upper fixing tape group 22112 to loosen the start end of the spare label tape it fixes. In this way, the automatic label receiving machine can automatically connect the start end of the spare label tape to the end of the working label tape without manual label receiving. Compared with the prior art, this effectively improves work efficiency and reduces the workload of workers. In addition, through the cooperation of the supply mechanism 210 and the label receiving mechanism 220, the label receiving operation can be carried out continuously.

[0047] Specifically, when the label detection component 2212 detects the working label tape, the controller controls the label receiving component 2213 and the upper fixing group 22112 to pause their operation, and the upper fixing group 22112 keeps the beginning of the spare label tape fixed. When the end of the working label tape moves through the radiation range of the label detection component 2212 and the label detection component 2212 no longer detects the working label tape, the controller controls the lower fixing group 22111 and the label receiving component 2213 to operate sequentially. The lower fixing group 22111 fixes the end of the working label tape, and the label receiving component 2213 pushes the beginning of the spare label tape fixed by the upper fixing group 22112 to move closer to the end of the working label tape to press against the end of the working label tape, so as to bond them together using the adhesive layer pre-formed on any of the opposite surfaces of the beginning of the spare label tape and the end of the working label tape, thereby achieving label receiving. Subsequently, the first end of the spare label tape is placed above the lower fixing tape group 22111 and within the radiation range of the label detection component 2212. At this time, the label detection component 2212 feeds back to the controller, and the controller controls the lower fixing tape group 22111 and the upper fixing tape group 22112 to release the end of the working label tape and the first end of the spare label tape respectively, and the label receiving component 2213 resets to complete the label receiving. The spare label tape is then connected to the working label tape for production use.

[0048] Preferably, the label receiving component 2213 is implemented as a cylinder.

[0049] Preferably, the upper fixing tape assembly 22112 includes an upper fixing tape body 221121 and an upper vacuum suction component 221122. The lower surface of the upper fixing tape body 221121 has multiple spaced upper suction holes 22112101 that communicate with its interior. The upper vacuum suction component 221122 communicates with the upper fixing tape body 221121. The first end of the spare working tape is positioned below the upper suction holes 22112101. The upper vacuum suction component 221122 is connected to the controller and is configured to suction gas from the upper fixing tape body 221121 and adhere and fix the first end of the spare label tape through the upper suction holes 22112101. The tag assembly 2213 is installed on the device body 100, and the upper fixing tape body 221121 is installed on the tag assembly 2213 so as to be driven by the tag assembly 2213 to press against the lower fixing tape body 221111.

[0050] Preferably, the upper vacuum suction component 221122 is implemented to include a vacuum pump.

[0051] Preferably, the main body 100 of the equipment includes a main body 110 and a rotating base 120. The spare supply area and the production supply area are both formed in the main body 110. The rotating base 120 is located above the lower fixing tape body 221111 and is pivotally connected to the main body 110. The upper fixing tape body 221121 and the label attaching assembly 2213 are both mounted on the rotating base 120. Under the rotation of the rotating base 120, the lower surface of the upper fixing tape body 221121 can correspond to or be offset from the upper surface of the lower fixing tape body 221111. When the two are offset, it is convenient to fix the beginning of the spare label tape, so as to avoid the gap between the two being too small and difficult to operate.

[0052] refer to Figure 1 The label receiving mechanism 220 further includes a cutting component 222, which includes a cutting element 2221 slidably mounted on the device body 100. The cutting element 2221 is configured to move along the width direction of the beginning of the spare label tape to cut it, so that the beginning of the spare label tape meets the label receiving requirements.

[0053] Preferably, the cutting element 2221 is implemented as a cutting knife.

[0054] The cutting component 222 further includes a measuring element 2222, which is adjacent to the cutting component 2221. The measuring element 2222 is used to measure the beginning of the spare label tape to determine the portion to be cut.

[0055] Preferably, the measuring element 2222 is implemented as a centimeter ruler.

[0056] refer to Figure 1 and Figure 5 The label feeding device 200 includes a label conveying mechanism 230, which includes a label conveying component 231. The label conveying component 231 includes a label feeding wheel assembly 2311. The working label tape that moves across the upper surface of the lower fixed belt assembly 22111 is wrapped around the label feeding wheel assembly 2311 and is driven by the label feeding wheel assembly 2311 to be conveyed.

[0057] Preferably, the feed wheel assembly 2311 includes a motor and a transmission wheel.

[0058] The label conveying mechanism 230 further includes a label feeding buffer assembly 232. The working label tape, passing over the surface of the label feeding wheel assembly 2311, is wound around the label feeding buffer assembly 232. The working label tape conveyed by the label feeding buffer assembly 232 is then conveyed to a labeling machine. The label feeding buffer assembly 232 is slidably mounted on the main body 100 by being driven up and down by the working label tape. In this way, the label feeding buffer assembly 232 coordinates the label receiving operation and the labeling operation of the labeling machine. That is, while the labeling machine is labeling, the label feeding buffer assembly 232 is moved upwards by the working label tape, ensuring that the labeling and receiving operations do not interfere with each other. This achieves automatic label receiving without stopping the labeling machine, greatly improving the working efficiency of the labeling machine.

[0059] In addition, the label feeding buffer assembly 232 coordinates the labeling speed of the labeling machine and the conveying speed of the label feeding wheel assembly 2311 by sliding up and down, eliminating the need to precisely adjust the conveying speed of the label feeding wheel assembly 2311 according to the labeling speed of the labeling machine, thereby improving the compatibility of the labeling machine and the automatic label receiving machine when used together and increasing the convenience of use.

[0060] Preferably, the label feeding buffer assembly 232 is rotatably snapped onto the device body 100 so that when the working label tape is being conveyed, the label feeding buffer assembly 232 can be driven by the working label tape to rotate, thereby reducing friction between the two and reducing wear during conveying.

[0061] The label conveying mechanism 230 includes a label feeding monitoring component 233, which includes at least one first limit detection element 2331. The first limit detection element 2331 is installed on the equipment body 100 and is used to detect whether the height of the label feeding buffer assembly 232 is not lower than the maximum value of a predetermined height range and not higher than the minimum value of a predetermined height range. The first limit detection element 2331 is communicatively connected to the controller, which selectively controls the start / stop of the automatic label applicator or the label feeding wheel assembly 2311 based on feedback from the first limit detection element 2331. In this way, the automatic label applicator can adapt to the state of the labeling machine, and the two can flexibly cooperate to achieve efficient operation.

[0062] In one example, a single first limit detection element 2331 is provided, located below the label feeding buffer assembly 232. The first limit detection element 2331 is used to detect the distance between itself and the label feeding buffer assembly 232. After the first limit detection element 2331 detects the distance between itself and the label feeding buffer assembly 232 and feeds it back to the controller, if the controller determines that the distance is within a predetermined height range, the controller controls the automatic label applicator to continue operating; if the controller determines that the distance is not lower than the maximum value of the predetermined height range, the controller controls the automatic label applicator to stop operating, indicating that the labeling speed of the labeling machine is too fast and needs to be stopped; if the controller determines that the distance is not higher than the minimum value of the predetermined height range, the controller controls the label feeding wheel assembly 2311 to stop operating, indicating that the labeling machine stops labeling and there is no need to feed the working label tape.

[0063] In a preferred embodiment of the above embodiments, the first limiting detection element 2331 is implemented as a distance sensor.

[0064] Preferably, two first limit detection elements 2331 are provided, and the two first limit detection elements 2331 are vertically spaced apart on the side of the label feeding buffer assembly 232. The upper first limit detection element 2331 is used to detect whether the height of the label feeding buffer assembly 232 is not lower than the maximum value of a predetermined height range, and the controller selectively controls the start and stop of the automatic label receiving machine based on the feedback from the upper first limit detection element 2331. The lower first limit detection element 2331 is used to detect whether the height of the label feeding buffer assembly 232 is not higher than the minimum value of a predetermined height range, and the controller selectively controls the start and stop of the label feeding wheel assembly 2311 based on the feedback from the lower first limit detection element 2331.

[0065] Specifically, when the labeling machine applies labels at a predetermined speed, the label feeding buffer assembly 232 slides between the two first limit detection elements 2331. At this time, neither of the two first limit detection elements 2331 detects the label feeding buffer assembly 232, and the controller controls the automatic label receiving machine to continue running. When the labeling machine applies labels too quickly, causing the label feeding buffer assembly 232 to be moved upward by the working label tape and detected by the first limit detection element 2331 located above, the controller controls the automatic label receiving machine to stop for shutdown processing. When the labeling machine stops applying labels, the label feeding buffer assembly 232 moves downward under its own gravity and is detected by the first limit detection element 2331 located below. At this time, the controller controls the label feeding wheel assembly 2311 to stop operating to stop conveying the working label tape.

[0066] Preferably, the first limiting detection element 2331 is implemented as a photoelectric sensor.

[0067] The tag supply monitoring component 233 further includes an exhaustion detection component 2332, which is configured to radiate a signal to the supply component 211 located in the production supply area to detect whether the corresponding supply component 211 has remaining working tag rolls. The exhaustion detection component 2332 is communicatively connected to the controller, which selectively adjusts the conveying speed of the tag supply wheel assembly 2311 based on the feedback from the exhaustion detection component 2332.

[0068] Preferably, the exhaustion detection element 2332 is implemented as a photoelectric sensor.

[0069] Specifically, when the exhaustion detection unit 2332 detects that there are still working label rolls remaining on the supply unit 211 located in the production supply area, the controller controls the label feeding roller group 2311 to convey the working label tape at a predetermined speed. As the working label rolls located in the production supply area and set on the corresponding supply unit 211 are continuously unwound and completely unwound, so that the exhaustion detection unit 2332 detects that there are no working label rolls on the supply unit 211 located in the production supply area, the controller controls the label feeding roller group 2311 to slow down in order to coordinate with the label receiving operation, so as to reduce the speed at which the working label tape moves on the surface of the lower fixing tape group 22111, so as to prevent the working label tape from moving too fast and causing the labeling position to be incorrect.

[0070] The label conveying component 231 further includes at least two auxiliary label feeding wheels 2312, which are rotatably mounted on the equipment body 100. The working label tape passing above the lower fixed tape group 22111 is wound around one of the auxiliary label feeding wheels 2312 and then conveyed to the label feeding wheel group 2311. The working label tape passing through the label feeding buffer assembly 232 is wound around one of the auxiliary label feeding wheels 2312 and then conveyed to the labeling machine.

[0071] refer to Figure 1 , Figure 5 and Figure 7 The automatic label applicator includes a paper receiving device 300, which includes a paper winding mechanism 310. The paper winding mechanism 310 includes at least one paper winding roller 311, which is rotatably mounted on the main body 100 of the equipment. The paper winding roller 311 rotates to wind up the backing paper separated by the label applicator.

[0072] Preferably, two paper rolls 311 are provided, and the two paper rolls 311 are spaced apart, so that when one paper roll 311 is winding up the bottom paper, the other is kept as a spare, for ease of operation.

[0073] The paper winding mechanism 310 includes a winding drive assembly 312, and the paper winding roller 311 is mounted on the winding drive assembly 312 to be driven by the winding drive assembly 312 to rotate.

[0074] It is worth mentioning that when there are two paper rolls 311, the two paper rolls 311 rotate in opposite directions, and both paper rolls 311 are connected to the winding drive assembly 312 so that they are driven by the winding drive assembly 312 to make one of them rotate while the other remains stationary.

[0075] In one embodiment, the winding drive assembly 312 includes a drive component, three turntables, two one-way bearings, and two belts. One turntable is connected to and driven by the drive component to rotate. The other two turntables are respectively fitted onto the two one-way bearings and coaxially connected to the two paper rolls 311 through the corresponding one-way bearings. The two one-way bearings rotate in opposite directions. The remaining two turntables are respectively fitted onto the two belts. Each belt is fitted onto a turntable connected to the drive component, so that when the drive component operates to drive the corresponding turntable to rotate, one of the two paper rolls 311 rotates synchronously in one direction through the belt drive, while the other remains stationary. Preferably, the drive component includes a motor.

[0076] The paper winding mechanism 310 further includes at least one roll weight detection element 313, which is mounted on the main body 100 and located outside one of the paper winding rollers 311. The roll weight detection element 313 is used to detect the amount of bottom paper wound corresponding to the paper winding roller 311. The roll weight detection element 313 is communicatively connected to the controller, and the winding drive assembly 312 is controllably connected to the controller. The controller selectively controls the operation of the winding drive assembly 312 based on the feedback from the roll weight detection element 313.

[0077] Preferably, the roll volume detection element 313 is implemented as a photoelectric sensor.

[0078] Preferably, two paper rolls 311 are provided, and the number of roll weight detection elements 313 is the same as the number of paper rolls 311. When the signals radiated by both roll weight detectors 313 are not blocked, the roll weight detectors 313 feed back to the controller, which controls the winding drive assembly 312 to continue operating in the same direction. As the roll-up of the bottom paper progresses, the thickness of the bottom paper wrapped around one of the roll rollers 311 gradually increases until the signal radiated by the corresponding roll weight detector 313 is blocked by the bottom paper. At this time, the roll weight detector 313 feeds back to the controller, which controls the winding drive assembly 312 to stop operating. The operator disconnects the bottom paper and wraps it around the other roll roller 311. Subsequently, the operator unwraps the bottom paper after winding up to the predetermined amount. At this time, the signals radiated by both roll weight detectors 313 are not blocked, and the roll weight detectors 313 feed back to the controller. The controller controls the winding drive assembly 312 to rotate in the opposite direction to drive the other roll roller 311 to rotate and wind up the bottom paper. At this time, the first roll roller 311 remains stationary.

[0079] In this way, by monitoring the winding progress of the bottom paper, the winding can be stopped in time when the required amount is reached. This allows the staff to cut the tape in time and wrap the bottom paper around another paper roll 311. After the bottom paper is unwound, the other paper roll 311 automatically winds it up. The whole process requires little manual intervention, is convenient and fast, and greatly improves winding efficiency.

[0080] The automatic label applicator also includes a backing paper conveying mechanism 320, which includes a take-up buffer assembly 321. The take-up buffer assembly 321 is slidably mounted on the main body 100 of the equipment. The backing paper separated from the labeling machine is partially attached to the lower surface of the take-up buffer assembly 321 and then conveyed to the roll roller 311. The take-up buffer assembly 321 can be driven by the backing paper to slide up and down within the main body 100 of the equipment to coordinate the labeling speed of the labeling machine and the winding speed of the roll roller 310. This ensures the tension of the backing paper during transmission, facilitating the winding operation.

[0081] The bottom paper conveying mechanism 320 includes a paper delivery monitoring component 322, which includes at least one second limit detection element 3221. The second limit detection element 3221 is installed on the device body 100 and is used to detect whether the height of the paper delivery buffer assembly 321 is not lower than the maximum value of a predetermined height range and not higher than the minimum value of a predetermined height range. The second limit detection element 3221 is communicatively connected to the controller, which selectively controls the start and stop of the automatic label attaching machine or the start and stop of the winding drive assembly 312 based on the feedback from the second limit detection element 3221.

[0082] In one example, a single second limit detection element 3221 is provided, located below the take-up buffer assembly 321. The second limit detection element 3221 is used to detect the distance between itself and the take-up buffer assembly 321. After the second limit detection element 3221 detects the distance between itself and the take-up buffer assembly 321 and feeds it back to the controller, if the controller determines that the distance is within a predetermined height range, the controller controls the automatic label attaching machine to continue operating; if the controller determines that the distance is not higher than the minimum value of the predetermined height range, the controller controls the automatic label attaching machine to stop operating, indicating that the label attaching speed of the labeling machine is too fast or the backing paper is broken, requiring a shutdown; if the controller determines that the distance is not lower than the maximum value of the predetermined height range, the controller controls the winding drive assembly 312 to stop operating, indicating that the label attaching machine stops labeling and does not need to rewind the backing paper.

[0083] In a preferred embodiment of the above embodiments, the second limiting detection element 3221 is implemented as a distance sensor.

[0084] Preferably, two second limit detection elements 3221 are provided, and the two second limit detection elements 3221 are vertically spaced apart on the side of the paper take-up buffer assembly 321. The upper second limit detection element 3221 is used to detect whether the height of the paper take-up buffer assembly 321 is not lower than the maximum value of a predetermined height range. The controller selectively controls the start and stop of the winding drive assembly 312 based on the feedback from the upper second limit detection element 3221. The lower second limit detection element 3221 is used to detect whether the height of the paper take-up buffer assembly 321 is not higher than the minimum value of a predetermined height range. The controller selectively controls the start and stop of the automatic label attaching machine based on the feedback from the lower second limit detection element 3221.

[0085] Specifically, when the labeling machine applies labels at a predetermined speed, the paper delivery buffer assembly 321 slides between the two second limit detection elements 3221. At this time, neither of the two second limit detection elements 3221 detects the paper delivery buffer assembly 321, and the controller controls the automatic labeling machine to continue running. When the labeling machine applies labels too quickly or the bottom paper breaks, causing the paper delivery buffer assembly 321 to move downwards under its own weight and be detected by the second limit detection element 3221 located below, the controller controls the automatic labeling machine to stop for shutdown processing. When the labeling machine stops applying labels, and the paper delivery buffer assembly 321 is driven upwards by the bottom paper and is detected by the second limit detection element 3221 located above, the controller controls the winding drive assembly 312 to stop winding the bottom paper.

[0086] Preferably, the second limiting detection element 3221 is implemented as a photoelectric sensor.

[0087] In this way, by monitoring the location of the paper receiving buffer component 321, timely feedback can be provided, effectively preventing the labeling machine from stopping labeling while the rewinding operation continues, which could lead to a breakage of the bottom paper tape. It can also stop the machine in time if the labeling machine labels too quickly or the bottom paper tape breaks, allowing the automatic label attaching machine and the labeling machine to work flexibly together.

[0088] The paper delivery monitoring component 322 further includes a position detection component 3222, which is installed on the main body 100 of the device. The position detection component 3222 is used to detect whether the height of the paper delivery buffer assembly 321 is not lower than a predetermined value within a predetermined height range. The position detection component 3222 is communicatively connected to the controller, and the controller is controllably connected to the winding drive assembly 312 to selectively adjust the operating speed of the winding drive assembly 312 based on the feedback from the position detection component 3222.

[0089] Preferably, the position detection element 3222 is implemented as a photoelectric sensor. When there are two second limit detection elements 3221, the position detection element 3222 is located between the two second limit detection elements 3221. When the take-up buffer assembly 321 is driven by the bottom paper and slides up and down between the position detection element 3222 and the second limit detection element 3221 located below, the position detection element 3222 does not detect the take-up buffer assembly 321. At this time, the controller controls the winding drive assembly 312 to run at a predetermined speed. When the take-up buffer assembly 321 is driven by the bottom paper and moves upward to be detected by the position detection element 3222, the controller reduces the running speed of the winding drive assembly 312.

[0090] In this way, by monitoring the position of the paper receiving buffer assembly 321, the winding speed can be adjusted in a timely manner, so as to avoid the situation where the labeling machine labels too slowly and the winding speed is too fast, causing the paper receiving buffer assembly 321 to move too high and correspond to the second limit detection piece 3221 located above, thus erroneously triggering the winding drive assembly 312 to stop, thereby increasing the flexibility of winding.

[0091] The bottom paper conveying mechanism 320 further includes an auxiliary paper conveying component 323. The auxiliary paper conveying component 323 includes at least one buffer auxiliary wheel 3231, which is rotatably mounted on the main body 100 of the equipment. The bottom paper separated by the labeling machine wraps around the buffer auxiliary wheel 3231, partially affixed to its upper surface, to increase the tension during bottom paper conveying. The bottom paper is conveyed sequentially by at least one of the buffer auxiliary wheels 3231 and the paper receiving buffer assembly 321. The buffer auxiliary wheel 3231 is located above the position detection element 3222. When the paper receiving buffer assembly 321 is moved upwards by the bottom paper to correspond with the second limiting detection element 3221 located above, the lower surface of the portion of the paper receiving buffer assembly 321 with the bottom paper wrapped around it must not be higher than the upper surface of the buffer auxiliary wheel 3231 with the bottom paper wrapped around it.

[0092] Preferably, multiple buffer auxiliary wheels 3231 are provided, and the multiple buffer auxiliary wheels 3231 are spaced apart in a manner that maintains the same horizontal height. The paper receiving buffer assembly 321 includes a buffer seat 3211 and multiple spaced paper receiving buffer wheels 3212. The buffer seat 3211 is slidably mounted on the device body 100, and the paper receiving buffer wheels 3212 are rotatably mounted on the buffer seat 3211. The bottom paper is wrapped around the buffer auxiliary wheel 3231 in a manner that partially adheres to the lower surface of the buffer auxiliary wheel 3231. The gap between two adjacent buffer auxiliary wheels 3231 is adapted to the size of one paper receiving buffer wheel 3212. The projections of the multiple buffer auxiliary wheels 3231 and the multiple paper receiving buffer wheels 3212 on the horizontal plane are spaced apart. The multiple buffer auxiliary wheels 3231 and the multiple paper receiving buffer wheels 3212 alternately convey the bottom paper to increase the tension of the bottom paper when it is conveyed.

[0093] The auxiliary paper conveying component 323 further includes at least two auxiliary paper conveying rollers 3232, which are rotatably mounted on the main body 100 of the equipment. The bottom paper separated from the labeling machine is wound around one of the auxiliary paper conveying rollers 3232 and then conveyed to the take-up buffer assembly 321 or the buffer auxiliary roller 3231. The bottom paper that has passed through the take-up buffer assembly 321 is wound around one of the auxiliary paper conveying rollers 3232 and then conveyed to the paper roll 311.

[0094] This application also proposes a method for operating an automatic label attaching machine, including the following steps:

[0095] One of the supply components 211 is disposed in the production supply area, and the working label tape formed by the unwinding of the working label roll corresponding to the supply component 211 moves above the lower fixing tape group 22111 and is conveyed to the label supply buffer assembly 232. Another supply component 211 is disposed in the spare supply area, and the spare label tape formed by the unwinding of the spare label roll corresponding to the supply component 211 is fixed by the upper fixing tape group 22112 with its first end placed at the bottom of the upper fixing tape group 22112.

[0096] As the working label roll is continuously unwound, the working label tape moves so that its end passes through the signal radiation range of the label detection element 2212, causing the label detection element 2212 to fail to detect the working label tape. At this time, the label detection element 2212 feeds back to the controller, and the controller controls the lower fixing tape group 22111 and the label receiving component 2213 to operate sequentially. The lower fixing tape group 22111 fixes the end of the working label tape, and the label receiving component 2213 pushes the beginning of the spare label tape, which is fixed by the upper fixing tape group 22112, to move closer to the end of the working label tape to press against the end of the working label tape. The adhesive layer pre-formed on either side of the opposite face of the beginning of the spare label tape and the end of the working label tape is used to bond them together. At the same time, the labeling machine performs the labeling operation and drives the label supply buffer component 232 to move upward through the working label tape, so that the labeling operation and the label receiving operation do not interfere with each other.

[0097] Subsequently, the first end of the spare label tape is placed above the lower fixing tape group 22111 and within the radiation range of the label detection component 2212. At this time, the label detection component 2212 feeds back to the controller, and the controller controls the lower fixing tape group 22111 and the upper fixing tape group 22112 to release the end of the working label tape and the first end of the spare label tape respectively, and the label receiving component 2213 resets to complete the label receiving. The spare label tape is then connected to the working label tape for production use.

[0098] Preferably, the operating method of the automatic label applicator further includes the following steps:

[0099] The usage detection element 212 detects the remaining quantity of the work tag roll located in the production supply area and installed on the corresponding supply element 211. When the work tag roll is about to run out, the usage detection element 212 feeds back to the controller, so that the controller controls the alarm to run to provide an early warning, so that the clerk can remove the corresponding supply element 211 in time.

[0100] Preferably, the operating method of the automatic label applicator further includes the following steps:

[0101] After the supply component 211 located in the production supply area is removed, the corresponding trigger 2133 detects the disassembly of the supply component 211 and the mounting component 2131. At this time, the trigger 2133 feeds back to the controller, and the controller controls the drive assembly 2132 to operate so that the drive assembly 2132 drives the two mounting components 2131 to switch positions, so that the mounting component 2131 with the corresponding trigger 2133 moves up to correspond to the spare supply area, and the other mounting component 2131 moves down to correspond to the production supply area. At this time, the spare label roll on the supply component 211 that is still assembled with the other mounting component 2131 is used for production.

[0102] Preferably, the operating method of the automatic label applicator further includes the following steps:

[0103] The exhaustion detection element 2332 radiates a signal to the supply element 211 located in the production supply area to detect whether the corresponding supply element 211 has any remaining working label rolls. When the working label rolls are used up, the exhaustion detection element 2332 feeds back to the controller, which controls the label feeding wheel assembly 2311 to slow down in coordination with the label receiving operation.

[0104] Preferably, the operating method of the automatic label applicator further includes the following steps:

[0105] The first limit detection element 2331 detects whether the height of the label feeding buffer assembly 232 is not lower than the maximum value of the predetermined height range and not higher than the minimum value of the predetermined height range. When the position of the label feeding buffer assembly 232 is too high or too low, the first limit detection element 2331 feeds back to the controller, and the controller controls the automatic label applicator to stop or the label feeding wheel assembly 2311 to stop, so as to adapt to the state of the labeling machine.

[0106] Preferably, the operating method of the automatic label applicator further includes the following steps:

[0107] The roll weight detection element 313 detects the bottom paper winding amount corresponding to the roll roll 311. After the winding amount reaches the requirement, the roll weight detection element 313 feeds back to the controller, and the controller controls the winding drive assembly 312 to make a feedback.

[0108] Preferably, the operating method of the automatic label applicator further includes the following steps:

[0109] When there are two paper rolls 311, if the signals radiated by the two roll weight detection elements 313 are not blocked, the roll weight detection elements 313 will feed back to the controller, and the controller will control the winding drive assembly 312 to continue to operate in the same direction.

[0110] As the rewinding action proceeds, the thickness of the paper wrapped around one of the paper rolls 311 gradually increases until the signal radiated by the corresponding roll weight detection element 313 is blocked by the paper. At this time, the roll weight detection element 313 feeds back to the controller, and the controller controls the rewinding drive assembly 312 to stop operating. The operator disconnects the paper and wraps it around another paper roll 311.

[0111] The staff then unwound the bottom paper that had been wound up to the predetermined amount. At this time, the signals radiated by the two roll quantity detection devices 313 were not blocked. The roll quantity detection devices 313 fed back to the controller, and the controller controlled the winding drive assembly 312 to rotate in the opposite direction to drive the other roll roller 311 to rotate and wind up the bottom paper. At this time, the first roll roller 311 remained stationary.

[0112] Preferably, the operating method of the automatic label applicator further includes the following steps:

[0113] The backing paper separated from the labeling machine is conveyed to the take-up buffer assembly 321, and then guided to the roll roller 311. During this process, the take-up buffer assembly 321 is driven by the backing paper and slides up and down on the main body 100 of the equipment to coordinate the labeling speed of the labeling machine and the winding speed of the roll mechanism 310.

[0114] Preferably, the operating method of the automatic label applicator further includes the following steps:

[0115] The second limit detection element 3221 detects whether the height of the paper receiving buffer assembly 321 is not lower than the maximum value of the predetermined height range and not higher than the minimum value of the predetermined height range. When the position of the paper receiving buffer assembly 321 is too high or too low, the second limit detection element 3221 feeds back to the controller. The controller controls the winding drive assembly 312 to stop or the automatic label attaching machine to stop, so as to adapt to the state of the labeling machine.

[0116] Preferably, the operating method of the automatic label applicator further includes the following steps:

[0117] When the position detection element 3222 detects that the height of the paper take-up buffer assembly 321 is not lower than a predetermined value within a predetermined height range, the position detection element 3222 feeds back to the controller, and the controller controls the winding drive assembly 312 to reduce its speed.
