[0032] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution in the utility model. Obviously, what is described is only a part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] In addition, it should be noted that the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0035] In label-related equipment, the label removal operation and the label replenishment operation correspond to different devices. After the label removal device removes the abnormal labels from the base material tape, the base material tape needs to be manually transported to the label replenishment device for label replenishment. This has a serious adverse effect on the smoothness of the label operation and the accuracy of label replenishment, and also causes a huge waste of labor costs, which is not conducive to improving the company's production efficiency.

[0036] In order to solve the above technical problems, the utility model proposes a device for removing and replenishing labels.

[0037] See also Figure 1-7 In one embodiment of the utility model, the label removing and label supplementing device comprises a frame 100, on which an unwinding mechanism 200, a label removing mechanism 300, a label supplementing mechanism 400 and a rewinding mechanism 500 are sequentially arranged;

[0038] The label rejection mechanism 300 is used to transfer abnormal labels on the base material belt 10 to the waste rejection belt 20; the label rejection mechanism 300 includes a first traction component 310, a waste rejection unwinding component 320, a waste rejection operation component 330 and a waste rejection rewinding component 340; driven by the first traction component 310, the waste rejection belt 20 passes through the waste rejection unwinding component 320, the waste rejection operation component 330 and the waste rejection rewinding component 340 in sequence, and the transfer of abnormal labels is completed through the waste rejection operation component 330; a first tension adjustment component 350 is provided between the waste rejection unwinding component 320 and the waste rejection operation component 330, and between the waste rejection operation component 330 and the waste rejection rewinding component 340, and the first tension adjustment component 350 is used to adjust the tension of the waste rejection belt 20;

[0039] Among them, the supplementary marking mechanism 400 is used to transfer the supplementary marking labels of the supplementary marking material tape 30 to the base material tape 10; the supplementary marking mechanism 400 includes a second traction component 410, a supplementary marking unwinding component 420, a supplementary marking operation component 430 and a supplementary marking rewinding component 440; driven by the second traction component 410, the supplementary marking material tape 30 passes through the supplementary marking unwinding component 420, the supplementary marking operation component 430 and the supplementary marking rewinding component 440 in sequence, and the transfer of the supplementary marking labels is completed through the supplementary marking operation component 430; a second tension adjustment component 450 is provided between the supplementary marking unwinding component 420 and the supplementary marking operation component 430, and between the supplementary marking operation component 430 and the supplementary marking rewinding component 440, and the second tension adjustment component 450 is used to adjust the tension of the supplementary marking material tape 30.

[0040] During operation, the technical solution of the present invention is driven by a main traction assembly (not shown in the drawings) to output the base material tape 10 from the unwinding mechanism 200, and sequentially passes through the label removing mechanism 300 and the label supplementing mechanism 400, and is finally recovered by the rewinding mechanism 500; wherein, the label removing mechanism 300 and the label supplementing mechanism 400 are integrated into the same device, which is different from the prior art in which the label removing operation and the label supplementing operation correspond to different devices, and the present invention can perform both the label removing operation and the label supplementing operation, thereby improving the production efficiency of the label operation and saving labor costs.

[0041] At the same time, considering that the waste material removal belt 20 and the label supplementing belt 30 of the label removal mechanism 300 and the label supplementing mechanism 400 are driven to move only when the corresponding label removal and label supplementing operations occur; and under normal circumstances, the base material belt 10 is in a high-speed operation mode, at this time, in order to match its speed, the waste material removal belt 20 and the label supplementing belt 30 will generate a strong instantaneous tension when switching from a static state to a moving state, causing tearing of the waste material removal belt 20 and the label supplementing belt 30; based on the above considerations, the utility model is provided in the label removal mechanism 300 A first tension adjusting component 350 is provided, and the tension of the waste rejection belt 20 is adjusted by the first tension adjusting component 350; and a second tension adjusting component 450 is provided in the marking supplementing mechanism 400, and the tension of the marking supplementing belt 30 is adjusted by the second tension adjusting component 450; so that the tension of the waste rejection belt 20 and the marking supplementing belt 30 can be adaptively adjusted to avoid the waste rejection belt 20 or the marking supplementing belt 30 from being torn due to excessive instantaneous tension, thereby ensuring the normal operation of the waste rejection belt 20 and the marking supplementing belt 30.

[0042] There are many implementation forms of the first tension adjustment component 350. In the embodiment of the present utility model, refer to the attached Figure 2-3The first tension adjustment assembly 350 includes a first adjustment roller 351 and a first adjustment mechanism 352 connected to each other. The waste removal belt 20 passes through the first adjustment roller 351. The first adjustment roller 351 can be displaced toward or away from the feeding direction of the waste removal belt 20 to adjust the tension of the waste removal belt 20. The first adjustment mechanism 352 is used to drive the first adjustment roller 351 to move. It can be understood that since the first adjustment roller 351 is a movable setting, when the waste removal belt 20 switches from a static state to a moving state, the instantaneous tension of the waste removal belt 20 increases. At this time, the waste removal belt 20 pulls the first adjustment roller 351 to make it displace toward the feeding direction of the waste removal belt 20, thereby reducing the tension of the waste removal belt 20 by reducing the stroke of the waste removal belt 20. When the labeling operation is completed and the waste material removal belt 20 switches from a moving state to a stationary state, the waste material removal belt 20 is prone to loosening due to the sudden release of tension at this time. At this time, the first adjusting mechanism 352 drives the first adjusting roller 351 to move in the direction opposite to the feeding direction of the waste material removal belt 20, and the first adjusting roller 351 is used to pull the waste material removal belt 20, thereby increasing the stroke of the waste material removal belt 20 so that the waste material removal belt 20 can always fit around the first adjusting roller 351, thereby preventing the waste material removal belt 20 from loosening. The purpose of adjusting the tension of the waste material removal belt 20 is achieved through the above technical solution.

[0043] In one embodiment, the first adjustment mechanism 352 includes an adjustment rod 3521 and a first spring 3522, the first end of the adjustment rod 3521 is connected to the first adjustment roller 351, and the second end of the adjustment rod 3521 is rotatably connected to the frame 100; the first end of the first spring 3522 is connected to the middle part of the adjustment rod 3521, and the second end of the first spring 3522 is fixedly connected to the frame 100; when the waste removal belt 20 drives the first adjustment roller 351 to displace due to tension, the first spring 3522 gives the first adjustment roller 351 a reverse force along its displacement direction through the adjustment rod 3521. With such arrangement, when the waste removal belt 20 switches from a stationary state to a moving state, the waste removal belt 20 is displaced toward the feeding direction of the waste removal belt 20, and the first spring 3522 is pulled; when the waste removal belt 20 switches from a moving state to a stationary state, the elastic force of the first spring 3522 serves as a force for resetting the first adjusting roller 351, that is, the first spring 3522 gives the first adjusting roller 351 a reverse force along its displacement direction through the adjusting rod 3521, thereby causing the first adjusting roller 351 to be displaced in the feeding direction away from the waste removal belt 20, so as to ensure the smooth implementation of the technical solution of the present application; and the above process does not require manual intervention, thereby realizing adaptive adjustment of the tension exerted on the waste removal belt 20.

[0044] Among them, since the first adjusting roller 351 is connected to the first end of the adjusting rod 3521, and the second end of the adjusting rod 3521 is rotatably connected to the frame 100, that is to say, the moving range of the first adjusting roller 351 is limited by the rotatable range of the adjusting rod 3521, the displacement amplitude of the first adjusting roller 351 is controlled within a certain range to avoid excessive displacement of the first adjusting roller 351.

[0045] There are many implementation forms of the waste rejection component 330. In the embodiment of the present utility model, refer to the attached Figure 2-3 The waste rejection component 330 includes a fixed roller 331, a movable roller 332 and a first driving device 333. The base material belt 10 is wound around the fixed roller 331, and the waste rejection belt 20 is wound around the movable roller 332. A gap is provided between the fixed roller 331 and the movable roller 332 for the base material belt 10 and the waste rejection belt 20 to pass through. The first driving device 333 is connected to the movable roller 332. The first driving device 333 is used to drive the movable roller 332 to move closer to the fixed roller 331, and to use The stickiness of the waste rejection belt 20 is used to transfer abnormal labels from the base material belt 10 to the waste rejection belt 20; when the first driving device 333 drives the movable roller 332 to approach the fixed roller 331, the waste rejection belt 20 and the abnormal labels on the base material belt 10 are brought into contact with each other; the stickiness of the waste rejection belt 20 to abnormal labels is greater than the stickiness of the base material belt 10 to abnormal labels, so that the abnormal labels can be transferred from the base material belt 10 to the waste rejection belt 20, and the structure is simple and practical.

[0046] Further, see Attachment Figure 2 The label rejection mechanism 300 further includes a first detection device 360, which is electrically connected to the first driving device 333 and the first traction assembly 310; the first detection device 360 ​​is used to detect whether there is an abnormal label on the base material belt 10. In this way, when the first detection device 360 ​​detects that there is an abnormal label on the base material belt 10, the first driving device 333 and the first traction assembly 310 are started, and the waste rejection belt 20 is driven to move by the first traction assembly 310, and the movable roller 332 is driven to approach the fixed roller 331 by the first driving device 333, so as to perform the label rejection operation.

[0047] In this embodiment, the first detection device 360 ​​can adopt a CCD visual detection system, which can accurately identify abnormal labels with various abnormalities such as appearance abnormality, size deviation, pattern missing, etc. on the base material belt 10, and then use the removal mechanism 300 to remove the labels.

[0048] The following is a brief description of the label removal operation of the base material belt 10 in combination with the above-mentioned embodiment: when the first detection device 360 ​​detects that there is an abnormal label on the base material belt 10, the first traction component 310 first drives the waste removal belt 20 to move so that its moving speed is basically the same as that of the base material belt 10, that is, the two are in a relatively static state; then the first driving device 333 drives the movable roller 332 to approach the fixed roller 331, so that the waste removal belt 20 and the abnormal labels on the base material belt 10 are in contact with each other; the adhesion of the waste removal belt 20 to the abnormal labels is greater than the adhesion of the base material belt 10 to the abnormal labels, so that the abnormal labels can be transferred from the base material belt 10 to the waste removal belt 20, and the label removal operation of the base material belt 10 is completed. After the label removal operation is completed, the first driving device 333 is driven again to reset the movable roller 332.

[0049] There are many implementation forms of the second tension adjustment component 450. In the embodiment of the present utility model, refer to the attached Figure 4-5 The second tension adjustment component 450 includes a second adjustment roller group 451 and a second adjustment mechanism (not shown in the drawings), wherein the second adjustment roller group 451 includes a first sub-adjustment roller 4511, a second sub-adjustment roller 4512 and a third sub-adjustment roller 4513, and the marking material belt 30 is wound around the first sub-adjustment roller 4511, the second sub-adjustment roller 4512 and the third sub-adjustment roller 4513 in sequence; the first sub-adjustment roller 4511 and the third sub-adjustment roller 4513 are fixedly connected to the frame 100, and the second sub-adjustment roller 4512 is slidably connected to the frame 100; the second sub-adjustment roller 4512 can be displaced toward or away from the feeding direction of the marking material belt 30 to adjust the tension of the marking material belt 30; the second adjustment mechanism is used to drive the second sub-adjustment roller 4512 to move. It can be understood that since the second sub-adjusting roller 4512 is a movable setting, when the supplementary marking material belt 30 switches from a static state to a moving state, the instantaneous tension borne by the supplementary marking material belt 30 increases; at this time, the supplementary marking material belt 30 pulls the second sub-adjusting roller 4512 to cause it to shift toward the feeding direction of the supplementary marking material belt 30, thereby reducing the tension borne by the supplementary marking material belt 30 by reducing the stroke of the supplementary marking material belt 30. When the marking operation is completed, the marking material belt 30 switches from a moving state to a stationary state. Since the tension is suddenly released at this time, the marking material belt 30 is likely to become loose. At this time, the second adjustment mechanism drives the second sub-adjusting roller 4512 to move in the direction opposite to the feeding direction of the marking material belt 30, and uses the second sub-adjusting roller 4512 to pull the marking material belt 30, thereby increasing the stroke of the marking material belt 30 so that the marking material belt 30 can always fit around the second sub-adjusting roller 4512, thereby preventing the marking material belt 30 from becoming loose. The above technical solution is used to achieve the purpose of adjusting the tension of the marking material belt 30.

[0050] More specifically, the frame 100 is provided with a sliding groove 110, the groove direction of the sliding groove 110 is located in the material running extension direction of the marking material belt 30; the second sub-adjusting roller 4512 is slidably connected to the sliding groove 110. That is to say, the moving range of the second sub-adjusting roller 4512 is limited by the groove range of the sliding groove 110, so that the displacement amplitude of the second sub-adjusting roller 4512 is controlled within a certain range, and the second sub-adjusting roller 4512 is prevented from excessive displacement.

[0051] Specifically, the second adjustment mechanism includes a second spring (not shown in the drawings), one end of the second spring is connected to the second sub-adjusting roller 4512, and the second end of the second spring is fixedly connected to the frame 100; when the second sub-adjusting roller 4512 is driven to move due to the tension of the supplementary marking material belt 30, the second spring gives the second sub-adjusting roller 4512 a reverse force along the displacement direction. In this way, when the supplementary marking material belt 30 switches from a static state to a moving state, the supplementary marking material belt 30 is displaced toward the feeding direction of the supplementary marking material belt 30, and the second spring is pulled; when the supplementary marking material belt 30 switches from a moving state to a static state, the elastic force of the second spring is used as the force for resetting the second sub-adjusting roller 4512, that is, the second spring gives the second sub-adjusting roller 4512 a reverse force along the displacement direction, so that the second sub-adjusting roller 4512 is displaced in the feeding direction away from the supplementary marking material belt 30, so as to ensure the smooth implementation of the technical solution of the present application; and the above process does not require manual intervention, and realizes the adaptive adjustment of the tension of the supplementary marking material belt 30.

[0052] There are many implementation forms of the supplementary mark operation component 430. In the embodiment of the present utility model, refer to the attached Figure 4 And attached Figure 6-7The labeling operation assembly 430 includes a labeling roller 431, a labeling plate 432 and a second driving device 433, wherein the labeling plate 432 has an acute-angle arc-shaped end portion 4321 at one end facing the labeling roller 431; the base material belt 10 is wound around the labeling roller 431, and the labeling material belt 30 is wound around the labeling plate 432, and a gap is provided between the labeling roller 431 and the labeling plate 432 for the base material belt 10 and the labeling material belt 30 to pass through; the second driving device 433 is connected to the labeling plate 432, and the second driving device 433 is used to drive the acute-angle arc-shaped end portion 4321 of the labeling plate 432 to move toward the labeling roller 431, so that the labeling label passes through the acute-angle arc-shaped end portion 4321. The end 4321 is separated from the supplementary marking material tape 30 and is transferred to the vacant position of the base material tape 10 as the supplementary marking material tape 30 is pushed; in this way, when the vacant position of the base material tape 10 is aligned with the acute-angled arc-shaped end 4321 of the supplementary marking plate 432, the second driving device 433 drives the acute-angled arc-shaped end 4321 of the supplementary marking plate 432 to move toward the supplementary marking roller 431. Since the supplementary marking material tape 30 is in a moving state at this time, the supplementary marking label is separated from the supplementary marking material tape 30 when passing the acute-angled arc-shaped end 4321, and is transferred to the vacant position of the base material tape 10 as the supplementary marking material tape 30 is pushed, thereby completing the supplementary marking operation of the base material tape 10.

[0053] Further, see Attachment Figure 4 The supplementary marking mechanism 400 further includes a second detection device 460, which is electrically connected to the second driving device 433 and the second traction assembly 410; the second detection device 460 is used to detect the position of the vacant position of the base material tape 10 and the position of the supplementary marking label of the supplementary marking tape 30. In this way, when the second detection device 460 detects the position of the vacant position of the base material tape 10 and the position of the supplementary marking label of the supplementary marking tape 30, by controlling the moving speed of the second traction assembly 410 on the supplementary marking tape 30, the supplementary marking label is exactly aligned with the vacant position of the base material tape 10 at the supplementary marking position, thereby performing the supplementary marking operation.

[0054] In this embodiment, the second detection device 460 includes a first positioning electric eye 461 and a second positioning electric eye 462. The first positioning electric eye 461 and the second positioning electric eye 462 respectively detect the position of the vacant position of the base material tape 10 and the position of the supplementary label of the supplementary marking material tape 30 to ensure the smooth implementation of the technical solution of the present application.

[0055] For details, please refer to the attached Figure 4The label-replenishing mechanism 400 further includes a pressing device 470, which is arranged at a downstream position of the label-replenishing roller 431; the pressing device 470 is used to press and fix the label-replenishing label and the base material belt 10. This arrangement ensures that the label-replenishing label and the base material belt 10 can be effectively connected after the label-replenishing operation is completed. In this embodiment, the pressing device 470 includes a pressing member 471 and a pressing drive device 472. The pressing drive device 472 drives the pressing member 471 to move toward the label-replenishing label so as to press the label-replenishing label onto the base material belt 10. The structure is simple and practical.

[0056] The following is a brief description of the marking operation of the base material tape 10 in combination with the above-mentioned embodiment: the first positioning electric eye 461 and the second positioning electric eye 462 in the second detection device 460 are used to detect the position of the vacant position of the base material tape 10 and the position of the supplementary marking label of the supplementary marking tape 30 respectively; at the same time, the second traction component 410 drives the supplementary marking tape 30 to move, and when the vacant position of the base material tape 10 is aligned with the acute-angled arc-shaped end 4321 of the supplementary marking plate 432, the second driving device 433 drives the acute-angled arc-shaped end 4321 of the supplementary marking plate 432 to move toward the supplementary marking roller 431. Since the supplementary marking tape 30 is in a moving state at this time, the supplementary marking label is separated from the supplementary marking tape 30 when passing the acute-angled arc-shaped end 4321, and is transferred to the vacant position of the base material tape 10 as the supplementary marking tape 30 is pushed, thereby completing the marking operation of the base material tape 10.

[0057] As a preferred solution of the above embodiment, refer to the attached Figure 1 , the unwinding mechanism 200 is provided with a material belt deviation correction device 600, or the rewinding mechanism 500 is provided with a material belt deviation correction device 600, or both the unwinding mechanism 200 and the rewinding mechanism 500 are provided with a material belt deviation correction device 600. In this way, the material belt deviation correction device 600 is used to perform wide-width deviation correction on the base material belt 10 released from the unwinding mechanism 200 and recovered to the rewinding mechanism 500, ensuring that the base material belt 10 can maintain the accuracy and stability of continuous operation at different speeds. Among them, since the material belt deviation correction material belt belongs to the prior art, this application will not be described in detail. In this embodiment, the material belt deviation correction device 600 is set in the unwinding mechanism 200.
