Description

Technical Field

[0001] This invention relates to the field of automatic labeling technology, and more particularly to a labeling device and labeling system. Background Technology

[0002] During the operation of labeling equipment, the labeling equipment often needs to first use the gluing mechanism to apply glue to the surface of the label being transported by the labeling equipment facing the outside of the labeling equipment, and then automatically label the bottles being transported by the external bottle feeding mechanism. However, due to reasons such as transport errors or bottle feeding errors, the external bottle feeding mechanism will inevitably have empty bottle positions.

[0003] In related technologies, empty bottle position detectors are usually used to detect whether there are empty bottle positions in the external bottle feeding mechanism. When an empty bottle position is detected, the labeling equipment is often stopped or slowed down in an emergency to avoid ineffective labeling operations on the empty bottle position. This would cause the adhesive labels to remain on the labeling equipment and be transported to other workstations, which could lead to adhesive dripping onto other workstations and hindering the operation of the mechanisms at those workstations.

[0004] However, since labeling equipment often operates at high speeds during operation, each emergency stop or deceleration will cause wear and tear on the equipment's structure, resulting in problems such as a short service life, difficulty in maintaining stable labeling accuracy over a long period of time, and high maintenance frequency. Summary of the Invention

[0005] One object of the present invention is to provide a labeling device that enables the labels transported by the labeling device to avoid the gluing mechanism, thereby eliminating the need for the labeling device to stop operating or slow down urgently.

[0006] Another objective of this invention is to provide a labeling system that, by setting up the aforementioned labeling equipment, enables the labeling system to have a longer overall service life and requires less maintenance.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] Firstly, a labeling device is provided, comprising:

[0009] A rotary wheel capable of rotating around its own first axis, the labeling device having an adhesive application area located on the outer periphery of the rotary wheel;

[0010] Multiple beacon-carrying components are evenly distributed around a first axis. Each beacon-carrying component includes a beacon-carrying mechanism, which includes a connected transmission connection structure and a beacon-collecting structure. The beacon-collecting structure is movably connected to the rotating wheel and is at least partially located on the outer periphery of the rotating wheel. An elastic element is connected between the beacon-carrying component and the rotating wheel, and the elastic element is capable of applying an elastic force to the beacon-carrying component, causing the beacon-collecting structure to tend to move away from the first axis.

[0011] A clutch mechanism is provided on one side of the rotating wheel. The clutch mechanism includes a first driving member, which can drive the transmission connection structure to move the label suction structure closer to the first axis.

[0012] As a preferred technical solution of the labeling equipment, the label conveying component includes two label conveying mechanisms spaced apart along the rotation direction of the rotating wheel, and the label suction structure of the two label conveying mechanisms can respectively suction the two opposite ends of the label;

[0013] The transmission connection structure of the two beacon mechanisms included in the beacon assembly can be driven by the same clutch mechanism, or the transmission connection structure of the two beacon mechanisms included in the beacon assembly can be driven by two different clutch mechanisms.

[0014] As a preferred technical solution of the labeling equipment, the clutch mechanism is located on one side of the rotary wheel corresponding to the glue application position. The clutch mechanism includes a first driving member and a clutch member. The first driving member can drive the clutch member to move relative to the rotary wheel, so that the clutch member abuts against the transmission connection structure corresponding to the glue application position, and the transmission connection structure drives the label suction structure to move closer to the first axis.

[0016] The transmission connection structure has a first end and a second end opposite to each other. The first end is transmissionally connected to the label suction structure, and the second end can abut against the clutch. The two second ends of the label transport assembly are at different distances from the central axis of the rotating wheel.

[0017] The labeling device includes two clutch mechanisms, and the first driving components of the two clutch mechanisms can respectively drive the two transmission connection structures of the label conveying assembly, so that the two transmission connection structures respectively drive the two label suction structures to approach the first axis.

[0018] For any one of the transmission connection structures corresponding to the upper glue position, along the radial direction of the rotating wheel, the two clutches are respectively located on two opposite sides of the second end. The clutches correspond to the second end that is closest to the rotating wheel along the radial direction, and the first driving member can drive the clutches to move along the radial direction of the rotating wheel so that the clutches abut against the corresponding second end.

[0019] As a preferred technical solution of the labeling device, the transmission connection structure has a first end and a second end opposite to each other, and the first end is transmissionally connected to the label suction structure;

[0020] The clutch has an abutting transition portion, an abutting portion, and a disengaging transition portion arranged sequentially along the rotation direction of the rotating wheel. The abutting transition portion has a first abutting surface capable of abutting the second end, the abutting portion has a second abutting surface capable of abutting the second end, and the disengaging transition portion has a third abutting surface capable of abutting the second end. The second abutting surface protrudes from the first abutting surface and the third abutting surface toward the second end corresponding to the upper adhesive position, and the second abutting surface smoothly transitions with the first abutting surface and the third abutting surface, respectively. And / or, the second end is provided with a roller that can abut against the clutch, or the clutch is provided with a roller that can abut against the second end.

[0021] As a preferred technical solution of the labeling equipment, the transmission connection structure includes a first structural body, a rotating shaft, a cam, and a second structural body. The first structural body is connected to the label suction structure and is slidably connected to the rotating wheel along the radial direction of the rotating wheel. The rotating shaft is rotatably disposed on the rotating wheel around its own second axis. The cam is provided on the outer periphery of the rotating shaft, and the outer peripheral surface of the cam abuts against the first structural body. One end of the second structural body is drivenly connected to the rotating shaft, and the other end of the second structural body can drive the rotating shaft to rotate around the second axis under the drive of the first driving member. The cam rotates under the drive of the rotating shaft, so that the outer peripheral surface of the cam can push the first structural body and the label suction structure as a whole to approach the first axis along the radial direction of the rotating wheel.

[0022] As a preferred technical solution of the labeling equipment, the first structural body includes a middle part and two connecting parts. The middle part abuts against the outer peripheral surface of the cam. The connecting parts are slidably connected to the rotating wheel along the radial direction of the rotating wheel. The connecting parts are connected between the middle part and the label suction structure, and the two connecting parts are respectively located at two opposite ends of the middle part.

[0023] In a second aspect, a labeling system is provided, comprising an empty bottle position detector, a label feeding mechanism, an adhesive application mechanism, and a labeling device as described in the first aspect above. Along the rotation direction of the rotating wheel, the labeling device has a top label position, an adhesive application position, and a labeling position arranged sequentially around the rotating wheel. The labeling device is used to label bottles delivered to the labeling position by an external bottle feeding mechanism. The empty bottle position detector is used to detect whether an empty bottle position exists in the external bottle feeding mechanism. The first driving member of the clutch mechanism can drive the transmission connection structure to move the label suction structure close to the first axis when the external bottle feeding mechanism detects the empty bottle position. The label feeding mechanism is set corresponding to the top label position, and the adhesive application mechanism is set corresponding to the adhesive application position.

[0024] As a preferred embodiment of the labeling system, the labeling system further includes a missing label rejection mechanism. Along the rotation direction of the rotating wheel, the labeling position, the missing label rejection mechanism, and the labeling position are arranged sequentially. The missing label rejection mechanism includes a label removal nozzle, a first storage box, and an air extraction device. The label removal nozzle is located close to the label conveying assembly. The interior of the label removal nozzle is connected to the interior of the first storage box. The air extraction device is also connected to the interior of the first storage box and can extract air from inside the first storage box towards the outside. Alternatively...

[0025] The labeling system also includes a cleaning mechanism. Along the rotation direction of the rotating wheel, the labeling position, the cleaning mechanism, and the labeling position are arranged in sequence. The cleaning mechanism includes a second driving component, a brush head, a second storage box, and a liquid extraction device. The second driving component is connected to the brush head, which can abut against the outer surface of the label suction structure. The second driving component can drive the brush head to move relative to the labeling device to clean the outer surface of the label suction structure. The brush head has a through liquid channel that connects to the interior of the second storage box. The interior of the second storage box contains cleaning agent, and the liquid extraction device can draw the cleaning agent from the interior of the second storage box into the liquid channel.

[0026] As a preferred technical solution of the labeling system, the labeling system further includes a missing label rejection mechanism and a cleaning mechanism. Along the rotation direction of the rotating wheel, the labeling position, the missing label rejection mechanism, the cleaning mechanism and the labeling position are arranged in sequence.

[0027] The missing label removal mechanism includes a label removal nozzle, a first storage box, and an air extraction device. The label removal nozzle is located close to the label transport component. The inside of the label removal nozzle is connected to the inside of the first storage box. The inside of the air extraction device is connected to the inside of the first storage box, and the air extraction device can extract the air inside the first storage box to the outside.

[0028] The cleaning mechanism includes a second driving component, a brush head, a second storage box, and a liquid extraction device. The second driving component is connected to the brush head, which can abut against the outer surface of the label suction structure. The second driving component can drive the brush head to move relative to the labeling device to clean the outer surface of the label suction structure. The brush head has a through liquid channel that communicates with the interior of the second storage box, which contains cleaning agent. The liquid extraction device can extract the cleaning agent from the interior of the second storage box into the liquid channel.

[0029] The beneficial effects of this invention are as follows:

[0030] By setting a transmission connection structure connected to the label suction structure and setting a clutch mechanism corresponding to the glue application position, when the external bottle feeding mechanism detects an empty bottle position, the first driving component can drive the transmission connection structure corresponding to the empty bottle position to rotate with the roller to the glue application position, thereby driving the label suction structure to move closer to the first axis. In other words, it drives the label suction structure away from the glue application mechanism, so that the label corresponding to the empty bottle position cannot contact the glue application mechanism and will not be glued. This avoids the adhesive being carried to other workstations by the labeling equipment, thus preventing the adhesive from falling to other workstations and hindering the operation of other workstations. The labeling equipment has a longer service life, the labeling accuracy can remain stable for a longer time, and the required maintenance frequency is lower. Attached Figure Description

[0044] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] like Figures 1 to 3 As shown, in a first aspect, the present invention provides a labeling device 1, including a rotary wheel 10, a plurality of label-carrying components 11, and a clutch mechanism 12. The rotary wheel 10 is rotatable around its own first axis 101. The labeling device 1 has an adhesive application position 1b located on the outer periphery of the rotary wheel 10. The plurality of label-carrying components 11 are evenly distributed around the first axis 101. Each label-carrying component 11 includes a label-carrying mechanism 110. The label-carrying mechanism 110 includes a transmission connection structure 1101 and a label-absorbing structure 1102 connected to each other. The label-absorbing structure 1102 is movably connected to the rotary wheel 10 and is at least partially located on the outer periphery of the rotary wheel 10. An elastic element 111 is connected between the label-carrying mechanism 110 and the rotary wheel 10 (see [link to relevant documentation]). Figure 7 In other words, an elastic element 111 is connected between the transmission connection structure 1101 and the rotating wheel 10, or an elastic element 111 is connected between the label-collecting structure 1102 and the rotating wheel 10, or both the transmission connection structure 1101 and the rotating wheel 10 are connected with an elastic element 111. The elastic element 111 can apply an elastic force to the label-carrying mechanism 110, causing the label-collecting structure 1102 to tend to move away from the first axis 101. The clutch mechanism 12 is located on one side of the rotating wheel 10. The clutch mechanism 12 includes a first driving member, which may include, but is not limited to, a linear motor, a rotary motor, or a cylinder. The first driving member can drive the transmission connection structure 1101 to move the label-collecting structure 1102 closer to the first axis 101.

[0048] By setting a transmission connection structure 1101 connected to the label suction structure 1102 and setting a clutch mechanism 12 corresponding to the glue application position 1b, when the external bottle feeding mechanism detects an empty bottle position, the first driving member can drive the transmission connection structure 1101 corresponding to the empty bottle position to rotate with the wheel 10 to the glue application position 1b, and drive the label suction structure 1102 to move closer to the first axis 101. In other words, it drives the label suction structure 1102 away from the glue application mechanism, so that the label corresponding to the empty bottle position cannot contact the glue application mechanism and will not be glued. This can prevent the adhesive from being carried to other workstations by the labeling equipment 1, thus avoiding the problem of adhesive falling to other workstations and hindering the operation of other workstations. The labeling equipment 1 has a longer service life, the labeling accuracy can remain stable for a longer time, and the required maintenance frequency is lower.

[0049] Optionally, the label-carrying assembly 11 includes two label-carrying mechanisms 110 spaced apart along the rotation direction S of the rotating wheel 10. Each label-carrying mechanism 110 includes a transmission connection structure 1101 and a label-absorbing structure 1102 connected to each other. The label-absorbing structures 1102 of the two label-carrying mechanisms 110 can respectively absorb the two opposite ends of the label, thereby making the structure of the label-carrying mechanism 110 more compact. At the same time, the label-carrying assembly 11 has better label-absorbing stability.

[0050] Alternatively, each of the beacon components 11 may be provided with a clutch mechanism 12, which can rotate with the wheel 10.

[0051] Furthermore, the transmission connection structure 1101 of the two beacon mechanisms 110 included in the beacon assembly 11 can be driven by the same clutch mechanism 12, or the transmission connection structure 1101 of the two beacon mechanisms 110 included in the beacon assembly 11 can be driven by two clutch mechanisms 12 respectively.

[0052] Alternatively, the clutch mechanism 12 is located on one side of the rotary wheel 10 corresponding to the glue application position 1b. In other words, the relative position of the clutch mechanism 12 and the glue application position 1b is fixed, and the clutch mechanism 12 does not rotate with the rotary wheel 10. Therefore, the number of clutch mechanisms 12 can be reduced, making the structure of the labeling device 1 simpler.

[0053] Optionally, the clutch mechanism 12 further includes a clutch element 121, which is driven by the first drive element to move relative to the rotating wheel 10, so that the clutch element 121 abuts against the transmission connection structure 1101 corresponding to the upper glue position 1b, and the transmission connection structure 1101 drives the label suction structure 1102 to move closer to the first axis 101.

[0054] like Figure 2 , Figure 4 and Figure 5As shown, to make the labeling device 1 more compact, the spacing between two adjacent label-carrying components 11 is usually smaller than the spacing between the two label-carrying mechanisms 110 included in a label-carrying component 11. Therefore, in order to ensure that the clutch 121 can abut against the two transmission connection structures 1101 throughout the entire process of the label-carrying component 11 at least partially corresponding to the adhesive application position 1b, while not affecting other label-carrying components 11 adjacent to the label-carrying component 11, optionally, the labeling device 1 may include two clutch mechanisms 12, and the clutches 121 of the two clutch mechanisms 12 are respectively The two transmission connection structures 1101 that can abut against the marker assembly 11 corresponding to the upper glue position 1b are all identical in structure. Therefore, between any two adjacent transmission connection structures 1101 that a clutch mechanism 12 can abut against, there is a non-corresponding transmission connection structure 1101. Thus, when the clutch 121 abuts against the transmission connection structure 1101 located at the upper glue position 1b, it will not affect the non-corresponding transmission connection structure 1101 adjacent to the corresponding transmission connection structure 1101.

[0055] Please combine Figure 7 As shown, it can be understood that when the clutch 121 moves away from the transmission connection structure 1101 under the drive of the first drive member, the suction structure 1102 moves toward the direction away from the first axis 101 to reset under the action of the elastic force of the elastic member 111.

[0056] Alternatively, the transmission connection structure 1101 has a first end 11011 and a second end 11012. The first end 11011 is transmissionally connected to the label-collecting structure 1102, and the second end 11012 can abut against the clutch 121. The two second ends 11012 of the label-carrying assembly 11 are at different distances from the first axis 101 of the rotating wheel 10. In other words, the two second ends 11012 of the label-carrying assembly 11 are offset from each other in the radial direction of the rotating wheel 10. Since each label-carrying assembly 11 has the same structure, the second end 11012 is offset from any adjacent second end 11012 in the rotation direction S in the radial direction of the rotating wheel 10. Therefore, when the clutch 121 abuts against any second end 11012, it will not affect the second end 11012 that is adjacent to the second end 11012 and belongs to the same label-carrying assembly 11 or to an adjacent label-carrying assembly 11.

[0057] Alternatively, as described in the aforementioned technical solution, the labeling device 1 may include two clutch mechanisms 12. For example, for any transmission connection structure 1101 corresponding to the upper glue position 1b, along the radial direction of the rotating wheel 10, two clutches 121 are respectively located on two opposite sides of the second end 11012. The clutches 121 correspond to the second end 11012 that is closest to the rotating wheel 10 in the radial direction, and the first driving member can drive the clutches 121 to move along the radial direction of the rotating wheel 10 so that the clutches 121 abut against the corresponding second end 11012. In other words, the two clutches 121 can move along the direction away from the first axis 101 and the direction close to the first axis 101 respectively to abut against the corresponding second end 11012. Thus, when the multiple second ends 11012 rotate with the rotating wheel 10 in the rotation direction S, the two clutches 121 can avoid interfering with the multiple second ends 11012. When the clutches 121 abut against the corresponding second end 11012, they will not affect the non-corresponding second end 11012.

[0058] Alternatively, the clutch 121 may include a first portion and a second portion connected together, the first portion having a first surface and the second portion having a second surface, the first surface and the second surface being offset along the radial direction of the wheel 10, and the first surface and the second surface being able to abut against the two second ends 11012 of the same caliper assembly 11 located at the upper glue position 1b.

[0059] In order for the clutch 121 to achieve two different states under the drive of the first drive member, namely, being spaced apart from the corresponding second end 11012 and abutting against the corresponding second end 11012, optionally, the speed at which the clutch 121 is driven by the first drive member can be controlled so that the surface of the clutch 121 abuts against the second end 11012 along a predetermined trajectory and drives the second end 11012 to move.

[0060] In one exemplary embodiment, the first drive member can be used to output linear motion, thereby enabling the clutch member 121 to move at a speed in the radial direction of the wheel 10 by controlling the first drive member, so that the surface of the clutch member 121 abuts against the second end 11012 along a predetermined trajectory and drives the second end 11012 to move.

[0061] In another exemplary embodiment, the first drive member can be used to output rotational motion, and the outer peripheral surface of the clutch member 121 includes at least two adjacent parts, the distance between which the two parts and the rotation axis 11014 of the rotational motion output by the first drive member is different. Thus, by controlling the speed at which the first drive member drives the clutch member 121 to rotate, the surface of the clutch member 121 abuts against the second end 11012 along a predetermined trajectory and drives the second end 11012 to move.

[0062] Alternatively, the first driving member can be used to move the contact surface of the clutch 121 to a position that abuts against or is in contact with the corresponding second end 11012.

[0063] Please combine Figure 6 As shown, at this time, the predetermined trajectory by which the clutch 121 abuts against and pushes the second end 11012 depends on the shape of the abutment surface of the clutch 121. Exemplarily, the clutch 121 may have an abutment transition portion 1211, an abutment portion 1212, and a disengagement transition portion 1213 arranged sequentially along the rotation direction S. The abutment transition portion 1211 has a first abutment surface 1211a capable of abutting against the second end 11012, the abutment portion 1212 has a second abutment surface 1212a capable of abutting against the second end 11012, and the disengagement transition portion 1213 has a third abutment surface 1213a capable of abutting against the second end 11012. The second abutment surface 1212a protrudes from the first abutment surface 1211a and the third abutment surface 1213a toward the second end 11012 corresponding to the upper adhesive position 1b. Surface 1212a smoothly transitions with the first abutting surface 1211a and the third abutting surface 1213a, thereby guiding the corresponding second end 11012 to abut against the second abutting surface 1212a through the first abutting surface 1211a, and making the movement trajectory of the second end 11012 smooth, avoiding additional vibration and impact. The second abutting surface 1212a keeps the second end 11012 in a position that drives the label suction structure 1102 away from the glue application mechanism. The third abutting surface 1213a guides the second end 11012 to disengage from the clutch 121, while making the movement trajectory of the second end 11012 smooth, avoiding additional vibration and impact.

[0064] Since the clutch 121 always corresponds to the glue application position 1b, and the label conveying assembly 11 needs to rotate relative to the glue application position 1b with the rotating wheel 10, when the clutch 121 abuts against the second end 11012, the clutch 121 and the second end 11012 are in a state of relative motion. In order to reduce the static electricity generated by the friction between the clutch 121 and the second end 11012 in this state, which affects the labeling operation of the labeling device 1, preferably, the second end 11012 is provided with a roller 13, which can abut against the clutch 121, or the clutch 121 is provided with a roller 13, which can abut against the second end 11012. Thus, the friction between the clutch 121 and the second end 11012 can be static friction through the roller 13, so as to reduce the generation of static electricity.

[0065] Please combine Figure 3 , Figure 5 and Figure 7As shown, optionally, the transmission connection structure 1101 includes a first structural body 11013, a rotating shaft 11014, a cam 11014a, and a second structural body 11015. The first structural body 11013 is connected to the label suction structure 1102, and the first structural body 11013 is slidably connected to the rotating wheel 10 along the radial direction of the rotating wheel 10. The rotating shaft 11014 is rotatably disposed on the rotating wheel 10 around its own second axis 11014b. The outer periphery of the rotating shaft 11014 is provided with a cam 11014a, and the outer peripheral surface of the cam 11014a abuts against the first structural body 11015. The main body 11013 and the second structural main body 11015 are connected at one end to the rotating shaft 11014. The other end of the second structural main body 11015 can abut against the clutch 121, so that the clutch 121 drives the second structural main body 11015 and the rotating shaft 11014 to rotate around the second axis 11014b. The cam 11014a rotates under the drive of the rotating shaft 11014, so that the outer peripheral surface of the cam 11014a can push the first structural main body 11013 and the label suction structure 1102 as a whole to approach the first axis 101 along the radial direction of the rotating wheel 10. Figure 7 The direction R indicated by the arrow in the diagram is the radial direction of the rotor 10.

[0066] It is understood that when the transmission connection structure 1101 has a first end 11011 and a second end 11012 as described in the aforementioned technical solution, the first structural body 11013 has the first end 11011 and the second structural body 11015 has the second end 11012.

[0067] Since the outer peripheral surface of the cam 11014a moves relative to the first structural body 11013 when the cam 11014a pushes the first structural body 11013, in order to reduce the friction generated during the process of the cam 11014a pushing the first structural body 11013 and thus reduce the static electricity generated, preferably, one of the cam 11014a and the first structural body 11013 can be provided with a roller 13, so that the cam 11014a and the first structural body 11013 abut against each other through the roller 13. Figure 7 As shown, Figure 7 The example shows that the first structural body 11013 is provided with a roller 13 so that the cam 11014a abuts against the first structural body 11013 via the roller 13.

[0068] Preferably, the first structural body 11013 includes a middle part 11013a and two connecting parts 11013b. The middle part 11013a abuts against the outer peripheral surface of the cam 11014a. The connecting parts 11013b are slidably connected to the rotating wheel 10 along the radial direction of the rotating wheel 10. The connecting parts 11013b are connected between the middle part 11013a and the label suction structure 1102. The two connecting parts 11013b are located at two opposite ends of the middle part 11013a, so that the force on the first structural body 11013 is more balanced and reasonable, and the transmission stability from the cam 11014a to the label suction structure 1102 is better.

[0069] Please combine Figure 8 As shown, optionally, the outer periphery of the rotating wheel 10 is provided with a setting groove 102, and the label-absorbing structure 1102 is partially slidably disposed in the setting groove 102 along the radial direction of the rotating wheel 10, so that the movement direction of the label-absorbing structure 1102 can be restricted by the setting groove 102, making the movement of the label-absorbing structure 1102 relative to the rotating wheel 10 more controllable.

[0070] Optionally, the label-carrying assembly 11 further includes a limiting member 112. The limiting member 112 is disposed on the outer periphery of the rotating wheel 10 and located between the two label-carrying mechanisms 110 of the label-carrying assembly 11. When the clutch 121 is not in contact with the transmission connection structure 1101, the label-absorbing structure 1102 protrudes at least partially toward the outer periphery of the rotating wheel 10 from the limiting member 112. The limiting member 112 is used to limit the position of the middle part of the label, preventing the middle part of the label from bending and causing the distance between the two ends of the label to become smaller, thus preventing it from being absorbed by the two label-absorbing structures 1102 with a fixed distance. In addition, by making the label-absorbing structure 1102 protrude at least partially toward the outer periphery of the rotating wheel 10 from the limiting member 112, it is easier to keep the two ends of the label absorbed by the label-absorbing structure 1102 away from the first axis 101, thereby making it easier to ensure that the two ends of the label can be glued at the glue application position 1b.

[0071] Preferably, the limiting member 112 can vacuum adsorb the label, so that the limiting effect of the limiting member 112 on the label is more effective and controllable.

[0072] like Figure 9 As shown, in a second aspect, the present invention provides a labeling system 2, including an empty bottle position detector 20, a label feeding mechanism 21, an adhesive application mechanism 22, and a labeling device 1 as described in the first aspect of the technical solution.

[0073] Please combine Figure 2As shown, specifically, along the rotation direction S of the rotary wheel 10, the labeling device 1 has a labeling position 1a, an adhesive application position 1b, and a labeling position 1c arranged sequentially around the rotary wheel 10. The labeling device 1 is used to label bottles conveyed to the labeling position 1c by an external bottle feeding mechanism. An empty bottle position detector 20 is used to detect whether there is an empty bottle position 200 in the external bottle feeding mechanism. When the external bottle feeding mechanism detects an empty bottle position 200, the first driving member of the clutch mechanism 12 can drive the transmission connection structure 1101 to move the label suction structure 1102 close to the first axis 101. The label feeding mechanism 21 is set for the labeling position 1a, and the adhesive application mechanism 22 is set for the adhesive application position 1b. Since the aforementioned labeling device 1 has a long service life and will not carry the adhesive label to positions other than the adhesive application position 1b and the labeling position 1c, it can avoid the problem of adhesive falling to other workstations and hindering the operation of other workstations. Therefore, the labeling system 2 has a long overall service life and requires less maintenance.

[0074] Optionally, the labeling system 2 also includes a missing label rejection mechanism 23. Along the rotation direction S, the labeling position 1c, the missing label rejection mechanism 23, and the labeling position 1a are arranged in sequence. The missing label rejection mechanism 23 includes a label removal nozzle, a first storage box, and an air extraction device. The label removal nozzle can be close to the label conveying component 11. The inside of the label removal nozzle is connected to the inside of the first storage box. The inside of the air extraction device is connected to the inside of the first storage box, and the air extraction device can extract the air inside the first storage box to the outside. Thus, the label corresponding to the empty bottle position 200 can be rejected by the missing label rejection mechanism 23, preventing the label conveying component 11 from rotating to the labeling position 1a again with the rotating wheel 10 while it is in a state of adsorbing the label, which would cause an error in the labeling process.

[0075] Since the labels corresponding to empty bottle positions 200 are free of adhesive, it avoids the situation where adhesive adheres to the label removal nozzle and the inside of the first storage box during the label removal process of the label removal mechanism 23, preventing blockage of the nozzle or difficulty in cleaning the first storage box. Furthermore, by having the label removal mechanism 23 remove excess labels by suction, the labels can be promptly returned to the first storage box, preventing them from drifting to other workstations and affecting their operation.

[0076] In other embodiments, the missing label rejection mechanism 23 may not be provided. When the label-carrying component 11 corresponding to the empty bottle position 200 rotates with the rotating wheel 10 to the labeling position 1a again in the state of adsorbing the label, the labeling mechanism may not stop, so as to promptly recover the unsuccessful labeling with the label carrier film, thereby allowing the label-carrying component 11 to adsorb the original label and rotate with the rotating wheel 10 to the adhesive application position 1b again.

[0077] Optionally, the labeling system 2 also includes a cleaning mechanism 24. Along the rotation direction S, the labeling position 1c, the cleaning mechanism 24, and the labeling position 1a are arranged sequentially. The cleaning mechanism 24 includes a second drive unit, a brush head, a second storage box, and a liquid extraction device. The second drive unit may include, but is not limited to, a linear motor, a rotary motor, or a cylinder. The second drive unit is connected to the brush head, which can abut against the outer surface of the label suction structure 1102. The second drive unit can drive the brush head to move relative to the labeling device 1 to clean the outer surface of the label suction structure 1102. The brush head has a through liquid channel that connects to the inner surface of the second storage box. The second storage box contains cleaning agent. The liquid extraction device can draw the cleaning agent from the inside of the second storage box into the liquid channel, so that the outer surface of the label suction structure 1102 can be cleaned by the cleaning mechanism 24. This prevents the outer surface of the label suction structure 1102 from having overflow or residual adhesive, which would affect the adsorption effect of the label suction structure 1102 on the label. At the same time, it also prevents the surface of other labels adsorbed by the label suction structure 1102 from also being covered with adhesive. This can improve the labeling yield of the labeling system 2, improve the automation level of the labeling system 2, and reduce the frequency of manual maintenance to clean the label suction structure 1102.

[0078] Furthermore, the cleaning mechanism 24 may also include a third driving member, which may include, but is not limited to, a linear motor, a rotary motor, or a cylinder. The third driving member can drive the brush head to approach or move away from the first axis 101, thereby enabling the brush head to approach the first axis 101 only when cleaning the label suction structure 1102 is required, so as to contact and brush the surface of the label suction structure 1102. For example, the cleaning frequency of the cleaning mechanism 24 on the label suction structure 1102 can be designed such that cleaning is performed once after a predetermined number of labeling operations are completed on a label suction structure 1102. In this case, the third driving member can drive the brush head to approach the first axis 101 after the label suction structure 1102 has completed the predetermined number of labeling operations.

[0079] Preferably, the labeling system 2 may include a missing label removal mechanism 23 and a cleaning mechanism 24. Along the rotation direction S, the labeling position 1c, the missing label removal mechanism 23, the cleaning mechanism 24 and the labeling position 1a are arranged in sequence, so that the missing label can be removed first and then the label suction structure 1102 can be cleaned and washed. The labeling system 2 has a better degree of automation, intelligence and rationality.
