Description

Technical Field

[0001] This utility model relates to the field of labeling equipment technology, and in particular to a label separation device. Background Technology

[0002] Hand-tear plastic bags are rolled into rolls in a specified quantity at the end of production, and each roll needs to be sealed to prevent the bag ends from unraveling. Large label sealing is one of the sealing methods used, and it is becoming increasingly popular due to its good product information display, aesthetic appeal, and protective effect. However, manual labeling is inefficient, costly, and produces inconsistent quality. Therefore, the inventor provides a rolling labeling machine to automate large labeling. Labels are delivered individually to the rolling device, requiring a method to pick up individual labels from the label stack to facilitate automated rolling. However, during the process of picking up the top label from the stack, negative pressure may cause one or more extra labels to be pulled up, affecting the rolling operation. To address this, the inventor also proposes a method to remove the extra labels during the picking process, such as... Figure 10 As shown, this paper-removing method mainly uses a vertically moving brush. However, during use, it was found that the brush's movement frequency is relatively slow, resulting in inconsistent label removal. Furthermore, because the height at which the top label is picked up by the device is not very high, the brush may pick up labels that were not originally attached within its vertical movement range, leading to even more disordered label paper. Therefore, the label separation method needs further improvement. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a label separation device that improves the stability of label separation and helps to ensure the neatness of the label stack.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a label separation device is installed on a frame, the frame stores a stack of labels and a single-sheet pickup device is installed on the frame, including a deflector seat located on one side of the pickup end of the label stack, a deflector wheel is rotatably installed on the deflector seat, a flexible paper-dispensing structure is provided on the wheel surface of the deflector wheel, a deflector driver is provided between the deflector wheel and the deflector seat, and the flexible paper-dispensing structure pushes the label downward when the deflector wheel rotates.

[0005] As a preferred technical solution, a separating feed device is provided between the separating seat and the frame. The separating seat includes a separating station and a clearance station. The separating station is used for the flexible paper separating structure to move the label.

[0006] As a preferred technical solution, the separating feed device includes a feed support that is oscillatingly mounted on the frame in a direction close to or away from the label stack, the separating seat is mounted on the feed support, and a feed drive cylinder is installed between the separating seat and the feed support; the frame is provided with an oscillating drive mechanism for driving the feed support to oscillate in the direction of the label stack.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0027] Example 1: As Figures 1 to 5 As shown, a label separation device is mounted on a frame 1. The frame 1 can be integrated with the labeling machine frame 1 or be a separate device; this is not a limitation. The frame 1 stores a stack of labels 2, and a single-sheet pickup device 3 is installed on the frame 1. Conventionally, a peripheral limiting structure 22 is provided around the label stack 2 on the frame 1 to ensure that the label stack 2 is stacked neatly. The single-sheet pickup device 3 is used to pick up the top label 21 of the label stack 2 each time. It can use a negative pressure suction nozzle to achieve the pickup function, and the pickup is performed from the end of the label 21 closest to the roller applicator 4, so that the soft label 21 can be effectively picked up from this end, and it is convenient to deliver it towards the roller applicator 4 with this end as the leading edge. In this embodiment, the end where the top label 21 is picked up is referred to as the pickup end.

[0028] This device includes a deflector 5 located on one side of the pickup end of the label stack 2. A deflector wheel 51 is rotatably mounted on the deflector 5. A flexible paper-pulling structure 52 is provided on the wheel surface of the deflector wheel 51. A deflector driver 53 is provided between the deflector wheel 51 and the deflector 5. The flexible paper-pulling structure 52 pushes the label 21 downward when the deflector wheel 51 rotates.

[0029] During the process of the single-sheet pickup device 3 picking up the top label 21 and lifting it, the label 21 will pass the height of the separating wheel 51. The separating driver 53 drives the separating wheel 51 to rotate, and the flexible paper-pulling structure 52 pushes the label 21 downward. The flexibility of the label 21 ensures that the picked-up label 21 will not detach from the adsorption, but other labels 21 that may be picked up can be separated from the picked-up label 21 under this pushing action. During this pushing process, the flexible paper-pulling structure 52 can use the rotation of the separating wheel 51 to generate a continuous pushing action on the pickup end of the label 21. The pushing action is frequent and forceful, resulting in a good separation effect and high separation efficiency for the lifted labels 21. This continuous pushing action will not affect other unlifted labels 21, which helps to ensure the neat state of the label stack 2.

[0030] Among them, such as Figures 1 to 4 As shown, the flexible paper-removing structure 52 described in this embodiment includes a plurality of rubber teeth disposed on the surface of the paper-removing wheel 51, utilizing the inherent softness of the rubber material to achieve a flexible paper-removing effect. When using rubber teeth, the paper-removing wheel 51 is also preferably made of rubber, and the two can be integrally molded. Furthermore, as... Figure 5 As shown, the flexible paper-removing structure 52 includes paper-removing bristles disposed on the wheel surface of the paper-removing wheel 51. The softness of the bristles is used to achieve a flexible paper-removing effect, and the effect is equivalent and should also be within the scope of the flexible paper-removing structure 52.

[0031] Preferably, the frame 1 is further provided with an air-blowing separation structure 6. When the flexible paper-pulling structure 52 moves the pickup end of the label 21, a gap is quickly generated between the attached label 21 and the pickup end of the uppermost picked-up label 21. The air-blowing separation structure 6 can use this gap to quickly blow airflow between the attached label 21 and the uppermost picked-up label 21, further accelerating the complete separation of the two. Figures 2 to 4 As shown, the air-blowing separation structure 6 in this embodiment includes an air-blowing nozzle disposed on the deflector seat 5. The air-blowing nozzle is connected to a blow-up control valve and an air pump, which is readily understood by those skilled in the art; therefore, the blow-up control valve and air pump are not shown in the figure. Preferably, the blow-up position of the air-blowing nozzle is not higher than the effective position on the flexible paper-dispensing structure 52, so as to quickly achieve the blowing-out effect after the paper is dispensed from the pickup end.

[0032] Preferably, a separating feed device 7 is provided between the separating seat 5 and the frame 1. The separating seat 5 includes a separating station and a clearance station. The separating station is used by the flexible paper-dispensing structure 52 to move the label 21. By setting the separating feed device 7, when it is not necessary to separate the label 21, the separating seat 5 can be moved out of the separating station and to the clearance station, so that the separating wheel 51, separating driver 53 and other structures can avoid the path of the single-sheet pickup device 3 delivering the label 21 to the rolling device 4.

[0033] The separating feed device 7 described in this embodiment includes a feed support 71 that is oscillatingly mounted on the frame 1 in a direction approaching or moving away from the label stack 2. The separating seat 5 is mounted on the feed support 71, and a feed drive cylinder 72 is installed between the separating seat 5 and the feed support 71. The frame 1 is provided with an oscillating drive mechanism 73 for driving the feed support 71 to oscillate towards the label stack 2. The feed drive cylinder 72 drives the separating seat 5 to move in the height direction, and the oscillating drive mechanism 73 causes the feed support 71 to oscillate towards or away from the label stack 2.

[0034] Furthermore, the swing drive mechanism 73 described in this embodiment includes an elastic force-applying element. The frame 1 is provided with a retraction guide structure 74, which is used to cause the detent seat 5 to move laterally away from the label stack 2 during the retraction process.

[0035] After the tag removal is completed, the feed drive cylinder 72 retracts, and the tag removal seat 5 descends to avoid the delivery path of the picked-up tag 21. During the descent, guided by the return guide structure 74, the feed support 71 simultaneously swings away from the tag stack 2. This causes the tag removal seat 5 to move laterally away from the tag stack 2, preventing it from disturbing the tag stack 2 during the retraction process and ensuring the tag stack 2 remains neat. Finally, the tag removal seat 5 reaches the avoidance position. Before tag removal is needed, the feed drive cylinder 72 extends, and the tag removal seat 5 rises. Under the elastic force of the swing drive mechanism 73, the tag removal seat 5 finally returns to the tag removal position along the reverse guide of the return guide structure 74, ready for tag removal.

[0036] The return guide structure 74 can be implemented as a guide slope structure fixedly mounted on the frame 1 and inclined downward in the direction away from the label stack 2. The elastic force-applying component used in the swing drive mechanism 73 can be a spring plate provided on the side of the feed drive cylinder 72 away from the label stack 2, or a tension spring on the side of the feed drive cylinder 72 close to the label stack 2, or a torsion spring provided at the swing pin of the feed support 71, etc. This embodiment does not limit the implementation, and the accompanying drawings only illustrate the spring plate.

[0037] Furthermore, those skilled in the art will recognize that the present embodiment is provided with the separating feed device 7 mainly as a preferred implementation to adapt to the situation where the height at which the single-sheet pickup device 3 picks up the label 21 is not high. When the height at which the single-sheet pickup device 3 picks up the label 21 is high, that is, when it can reach a height higher than the separating wheel 51 after picking up the label 21, the present embodiment may not need to provide the separating feed device 7.

[0038] Example 2: Figure 6 and Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the swing drive mechanism 73 includes a swing drive cylinder, which is conventionally hinged between the feed support 71 and the frame 1. The extension and retraction of the swing drive cylinder drives the feed support 71 to swing in conjunction with the deflector 5. In this structure, the retraction guide structure 74 is no longer required on the frame 1. Furthermore, after the swing drive cylinder extends, its own extension length can be used as a limit, or a limit on the swing position of the label stack 2 can be provided on the frame 1 to achieve precise positioning of the swing position after swing drive.

[0039] Example 3: Figure 8 and Figure 9As shown, the difference between this embodiment and Embodiment 1 is that the separating feed device 7 includes a feed drive cylinder 72 mounted on the frame 1. The drive end of the feed drive cylinder 72 extends obliquely towards the separating station, and the separating seat 5 is fixedly mounted on the drive end of the feed drive cylinder 72. Through this obliquely positioned feed drive cylinder 72, when separating is not required, the separating seat 5 can be directly driven to descend, and this descent process simultaneously produces a lateral movement away from the label stack 2.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model. For example, the three embodiments above only provide technical guidance for the vertical feeding and retraction of the disengagement seat 5; other directions such as horizontal feeding and retraction are also possible. These changes and modifications all fall within the scope of this utility model as claimed. The scope of protection of this utility model is defined by the appended claims and their equivalents.
