Description

Technical Field

[0001] This invention relates to the field of automated equipment technology, and more specifically, to a labeling method and system. Background Technology

[0002] In the field of product packaging, to achieve purposes such as product information identification, anti-counterfeiting traceability, and compliance labeling, it is usually necessary to label multiple surfaces of the packaging box. Currently, existing technologies for multi-sided labeling of boxes mainly employ a separate labeling method to complete the labeling operation for each surface.

[0003] However, existing technologies that label multiple sides of a box individually result in a cumbersome process because each side requires independent positioning, labeling, resetting / transferring operations. The core reason for this problem is that the labeling operations for each side are independent and lack an integrated synchronous processing mechanism. This necessitates frequent starting and stopping of the equipment and adjustments to the box's posture during the labeling process, thereby prolonging the overall labeling time for a single box and ultimately leading to low labeling efficiency. Summary of the Invention

[0004] To address the problem of low labeling efficiency, this invention provides a labeling method and system.

[0005] In a first aspect, the present invention discloses a labeling method, the labeling method comprising:

A label is simultaneously applied to the first labeling unit and the second labeling unit. The first labeling unit, the second labeling unit, and the label form a labeling space. Then, a moving component moves one side of the box at the labeling position to abut the label. The moving component then moves the box to the labeling state, so that at least part of the box and at least part of the label are located in the labeling space. This allows the label to adhere to three adjacent outer surfaces of the box, thereby simplifying the labeling process, shortening the labeling time per box, improving labeling efficiency, and ultimately solving the problems of complex operation, long time, and low efficiency of traditional labeling methods.

Unless otherwise stated, "a plurality of" means two or more.

[0050] During the labeling process of attaching the label body 42 to the three adjacent outer surfaces of box 50, the traditional operation method lacks a reasonable spatial positioning structure. It cannot utilize the stable labeling space formed by the first labeling unit 22, the second labeling unit 23, and the label body 42 to assist labeling. Instead, it requires step-by-step adjustments to the actions of the label feeding unit 21 and the moving component 30 to position the labeling on each outer surface of box 50 separately. Each positioning step requires a separate operation to ensure the adhesion accuracy between the label body 42 and the outer surface of box 50. This prevents the synchronous adhesion of the label body 42 to the three adjacent outer surfaces of box 50, making the overall operation cumbersome and time-consuming, ultimately resulting in low labeling efficiency.

[0051] Example 1:

[0052] This embodiment discloses a labeling method, such as... Figure 1 As shown, the labeling method includes steps S10 to S30, which are executed sequentially. Detailed explanations of each step are as follows:

[0053] Label 40 includes a base body 41 and a label body 42; the base body 41 and the label body 42 are respectively set as sheet-like bodies;

[0054] The label feeding unit 21 includes a storage cylinder 211, a label feeding section 212, and a separation plate 213. The storage cylinder 211 is used to store the mutually adhesive bottom body 41 and label body 42. The label feeding section 212 is used to drive the bottom body 41. The separation plate 213 is located on the side of the first labeling unit 22 away from the second labeling unit 23, providing a structural basis for the orderly delivery of the label 40. Furthermore, the label feeding unit 21 also includes a storage section for storing the label 40.

[0055] In step S10, the label feeding unit 21 moves a label body 42 to the labeling state; wherein, the labeling state includes a first labeling unit 22 and a second labeling unit 23 spaced apart, and a label body 42 simultaneously adheres to the first labeling unit 22 and the second labeling unit 23, and the first labeling unit 22, the second labeling unit 23 and the label body 42 surround to form a labeling space; the first labeling unit 22 and the second labeling unit 23 can be components that generate negative pressure, and the label body 42 is adhered to the first labeling unit 22 and the second labeling unit 23 by negative pressure.

[0056] In step S20, the label feeding unit 21 moves a label body 42 to the labeling state, and the moving component 30 moves one side of the box 50 at the labeling position (i.e., the box 50 within the working range of the moving component 30) to abut the label body 42; wherein, the box 50 at the labeling position is located on the side of the label body 42 away from the labeling space, at which time the box 50 and the label body 42 make initial contact, preparing for the box 50 to enter the labeling space to complete the labeling action;

[0057] In step S30, the moving component 30 moves one side of the box 50 at the labeling position to abut the label surface 42, and the moving component 30 continues to move the box 50 to the labeling state. During the process of the box 50 entering the labeling space after abutting with the label 40, the label 40 abutting with the first labeling unit 22 moves downwards relative to the first labeling unit 22, and the label 40 abutting with the second labeling unit 23 moves upwards relative to the second labeling unit 23. The labeling state includes at least a portion of the box 50 and at least a portion of the label surface 42 being located in the labeling space; the label surface 42 adheres to three sequentially adjacent outer surfaces of the box 50 (the box 50 can be a cuboid or a cube, such as...). Figure 2The three outer surfaces shown can be the upper surface, lower surface, and a side surface adjacent to the upper and lower surfaces of the box 50. At least one of the box 50 and the label body 42 is adhesive. By placing at least a portion of the box 50 and at least a portion of the label body 42 in the labeling space, the label body 42 adheres to the three sequentially adjacent outer surfaces of the box 50, ensuring the adhesion accuracy between the label body 42 and the outer surfaces of the box 50, thereby achieving efficient labeling.

[0058] Furthermore, such as Figure 3 As shown, the conveying assembly 10 includes a conveyor belt 11, a conveying drive unit 12, and a detection unit 13. The conveyor belt 11 is driven to connect with the conveying drive unit 12, and the detection unit 13 can detect the placement status of the box 50 on the conveyor belt 11, such as whether there is a box 50 or not.

[0059] Furthermore, such as Figure 4 As shown, the first labeling unit 22 includes a first labeling plate 221 and a first bonding module 222; the second labeling unit 23 includes a second labeling plate 231, a second bonding module 232, and a moving part 234; the moving part 234 is drivenly connected to the second labeling plate 231; the second labeling plate 231 is disposed below the first labeling plate 221.

[0060] Step S10 includes steps S11 to S14. Steps S11, S12, S13, S14, S20, and S30 are executed sequentially. Detailed explanations of each step are as follows:

[0061] In step S11, based on the labeling instruction, the second labeling plate 231 moves to a distance of 0~10mm from the first labeling plate 221 in the vertical direction within a first set range. At this time, the distance between the second labeling plate 231 and the first labeling plate 221 in the vertical direction is small, so as to prevent the label 40 from entering the space between the second labeling plate 231 and the first labeling plate 221 in the vertical direction during the process of moving from the labeling unit 21 to the second labeling plate 231.

[0062] In step S12, based on the fact that the second labeling plate 231 moves to a distance from the first labeling plate 221 in the vertical direction within a first set range, the label feeding unit 21 moves a label body 42 to a first initial state; wherein, the first initial state includes the label body 42 being located in the area projected by the label feeding unit 21, the first labeling plate 221, and the second labeling plate 231 toward the labeling position direction, and part of the label body 42 is adhered to the label feeding unit 21, thereby achieving the initial positioning of the label body 42 and ensuring that the subsequent adhesion of the label body 42 to the box 50 is convenient;

[0063] In step S13, a label body 42 is moved to the first initial state based on the label feeding unit 21, and the second bonding module 232 drives the label body 42 to move to the second labeling plate 231 to achieve stable contact between the label body 42 and the second labeling plate 231, providing a basis for the label body 42 to move downward.

[0064] In step S14, the label body 42 is moved to the second labeling plate 231 based on the second bonding module 232. The moving part 234 drives the label body 42 to move downward through the second labeling plate 231, and the first bonding module 222 drives the label body 42 to bond with the first labeling plate 221 to the state to be bonded. During the process of the moving part 234 driving the label body 42 to move downward through the second labeling plate 231, the label body 42 and the first labeling plate 221 move relative to each other. At least part of the label body 42 and the second labeling plate 231 remain relatively stationary (if the label body 42 has wrinkles, the label body 42 and the second labeling plate 231 will be relatively displaced; if the label body 42 does not have wrinkles, the label body 42 and the second labeling plate 231 will be relatively stationary). By allowing the label body 42 to bond with the second labeling plate 231 before moving downward, wrinkles on the label body 42 can be prevented, and the flatness of the label body 42 can be guaranteed.

[0065] Furthermore, such as Figure 4 As shown, the first labeling unit 22 also includes a first roller 223, which is used to reduce the friction between the label body 42 and the first labeling plate 221 when they move relative to each other. The first bonding module 222 also includes a first suction part 2221 and a first vent 2222, which are used to adsorb the label 40 onto the first labeling plate 221.

[0066] Further, step S14 includes steps S141 to S143, with steps S11, S12, S13, S141, S142, S143, S20, and S30 executed sequentially. Detailed explanations of each step are as follows:

[0067] In step S141, the label body 42 is moved to the second labeling plate 231 based on the second bonding module 232, and the moving part 234 drives the second labeling plate 231 to move down to the second initial state through the second labeling plate 231; wherein, the second initial state includes a set proportion (which may be 5%~10%) of the label body 42 being adhered to the label feeding unit 21; by retaining part of the adhesive relationship between the label body 42 and the label feeding unit 21, a transition condition is provided for the subsequent separation of the label body 42.

[0068] In step S142, the moving part 234 drives the second labeling plate 231 to move down to the second initial state, and the first bonding module 222 drives part of the label surface 42 to bond with the first labeling plate 221.

[0069] In step S143, based on the first bonding module 222 driving a portion of the label body 42 to adhere to the first labeling plate 221, the moving part 234 continues to drive the label body 42 downward to the ready-to-be-labeled state via the second labeling plate 231. During the downward movement of the label body 42 driven by the moving part 234 via the second labeling plate 231, the label body 42 moves relative to the first labeling plate 221, while at least a portion of the label body 42 remains relatively stationary relative to the second labeling plate 231. By driving the second labeling plate 231 downward to bring the label body 42 into contact with the first labeling plate 221 just before the label body 42 leaves the labeling unit 21, and then allowing the label body 42 to leave the labeling unit 21, the operating time of the first bonding module 222 can be reduced, achieving an energy-saving effect.

[0070] Furthermore, during the process where the moving part 234 drives the label body 42 to move downward via the second labeling plate 231, and the first bonding module 222 drives the label body 42 to bond with the first labeling plate 221 to the bonding state, the force between the second labeling plate 231 and the label body 42 is greater than the force between the first labeling plate 221 and the label body 42. By controlling the force between the second labeling plate 231 and the label body 42 to be greater than the force between the first labeling plate 221 and the label body 42, the label body 42 can move downward stably, preventing the second labeling plate 231 from failing to pull down the label body 42, thus ensuring the stability of the downward movement of the label body 42.

[0071] Furthermore, the second labeling unit 23 also includes a second roller 233, used to reduce the frictional force when the label body 42 moves relative to the second labeling plate 231. The second bonding module 232 also includes a second suction part 2321 and a second vent 2322, used to adsorb the label 40 onto the second labeling plate 231.

[0072] Furthermore, such as Figure 2 As shown, the labeling assembly 20 also includes an air blowing unit 24; the air blowing unit 24 is disposed on the side of the first labeling plate 221 near the labeling position;

[0073] Step S142 includes the first bonding module 222 and the air blowing unit 24 jointly driving the label body 42 to abut against the first labeling plate 221. Since the first labeling plate 221 is above the second labeling plate 231, and is affected by gravity, the label body 42 may fall off when only the first bonding module 222 is used to bond the label body 42. The air blowing unit 24 can make the label body 42 abut against the first labeling plate 221 more securely. At the same time, if the upper end of the label body 42 is tilted, the air blowing unit 24 can more effectively make the label body 42 abut against the labeling plate, ensuring the bonding effect between the label body 42 and the first labeling plate 221.

[0074] Furthermore, the labeling method also includes step S144, and steps S11, S12, S13, S141, S142, S143, S144, S20, and S30 are executed sequentially.

[0075] In step S144, the moving part 234 drives the label body 42 to move down to the labeling state via the second labeling plate 231, and the air blowing unit 24 stops working. Since the label body 42 is now stably attached to the first labeling plate 221, stopping the air blowing unit 24 can achieve energy saving and reduce the energy consumption of the equipment.

[0076] Furthermore, step S30 includes steps S31 to S32, with steps S10, S20, S31, and S32 executed sequentially. Detailed explanations of each step are as follows:

[0077] In step S31, the side of the box 50 at the labeling position is moved to abut the label body 42 based on the moving component 30, thereby reducing the force between the second labeling unit 23 and the label body 42, and using gravity to assist the label body 42 in abutting the box 50, thus achieving an energy-saving effect.

[0078] In step S32, based on reducing the force between the second labeling unit 23 and the label body 42, the moving component 30 moves the box 50 to the labeling state. This achieves precise movement of the box 50, ensuring that the box 50 smoothly enters the labeling space to complete the labeling operation, and the upper force is not reduced, thus ensuring the stability of the label body 42's upper part.

[0079] Example 2:

[0080] This embodiment discloses a labeling system, which is applied to any of the labeling methods in Embodiment 1, such as... Figure 2 As shown, the labeling system also includes:

[0081] Label 40 includes a bottom surface 41 and a label surface 42; the bottom surface 41 and the label surface 42 are respectively set as sheet-like bodies;

[0082] The label feeding unit 21 includes a storage cylinder 211, a label feeding part 212, and a separation plate 213; the storage cylinder 211 is used to store the mutually adhesive bottom body 41 and label body 42; the label feeding part 212 is used to drive the bottom body 41; the separation plate 213 is located on the side of the first labeling unit 22 away from the second labeling unit 23, providing a structural basis for the orderly delivery of the label 40;

[0083] The label delivery unit 21 moves a label body 42 to the first initial state, including:

[0084] The label feeding unit 212 moves the label 40 in the storage cylinder 211 to the feeding state; wherein, the feeding state includes the separation plate 213, the bottom body 41, the label body 42, and the labeling position arranged in sequence along the horizontal direction; the bottom body 41 at least abuts against the side of the separation plate 213 near the labeling position; the minimum included angle between the bottom body 41 on the side of the separation plate 213 near the labeling position and the bottom body 41 on the side of the separation plate 213 near the first labeling plate 221 is less than a set angle, thereby realizing the feeding and positioning of the label 40, ensuring that the contact angle between the bottom body 41 and the separation plate 213 meets the preset requirements, and providing conditions for the separation of the label body 42 and the bottom body 41;

[0085] The label delivery unit 212 continues to drive the label body 42 to move until it separates from the bottom body 41, and then drives the label body 42 towards the first labeling unit 22 to the first initial state via the bottom body 41. This achieves reliable separation between the label body 42 and the bottom body 41, and simultaneously completes the movement and initial positioning of the label body 42 towards the first labeling unit 22, ensuring the orderly progress of subsequent labeling operations.

[0086] Furthermore, the conveying assembly 10 is used to convey the box 50, which can be a cuboid or a cube;

[0087] The labeling component 20 includes a label feeding unit 21, a first labeling unit 22, and a second labeling unit 23; the label feeding unit 21, the first labeling unit 22, and the second labeling unit 23 are arranged sequentially.

[0088] The moving component 30 is used to drive the box 50 in the labeling area on the conveying component 10;

[0089] The labeling system operates by having the label feeding unit 21 move the label body 42 to a ready-to-be-labeled state, and the moving component 30 driving the box 50 in the labeling area of ​​the conveying component 10 to a labeling state. In this labeling state, at least a portion of the box 50 and at least a portion of the label body 42 are located in the space between the first labeling unit 22 and the second labeling unit 23. The label body 42 abuts against three sequentially adjacent outer surfaces of the box 50. By placing at least a portion of the box 50 and at least a portion of the label body 42 in the labeling space, the label body 42 adheres to the three sequentially adjacent outer surfaces of the box 50, ensuring the adhesion accuracy between the label body 42 and the outer surfaces of the box 50, thereby achieving efficient labeling.

[0090] Furthermore, the second labeling unit 23 includes a second labeling plate 231, a second bonding module 232, and a moving part 234; the second labeling plate 231 is disposed below the first labeling unit 22; the moving part 234 is drivenly connected to the second labeling plate 231, providing drive and support for the downward movement and bonding of the label body 42;
