Description

Technical Field

[0001] This invention relates to the field of automation technology, specifically to a labeling device. Background Technology

[0002] In related technologies, the labeling process in lens packaging is mostly done manually. Due to the numerous process steps, low manual efficiency, and high production costs, the manual labeling process seriously affects the production efficiency of lens packaging. Summary of the Invention

[0003] In view of this, embodiments of this application aim to provide a labeling device capable of applying labels to packaging bags.

[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows: This invention provides a labeling device for affixing labels to packaging bags. The labeling device includes: A labeling module, the labeling module comprising a first picking and placing component for picking and placing packaging bags and a second picking and placing component for picking and placing labels; A storage module is provided with a storage space for stacking packaging bags. The storage space is open on one side along a first stacking direction to form a storage opening, and a first elastic member that can move along the first stacking direction is provided on the other side. A limiting component is provided on the side of the storage space near the storage opening. The labeling module is located on the side of the storage space near the storage opening along the first stacking direction. Both the first pick-and-place component and the second pick-and-place component can move toward the storage space so that the first pick-and-place component stacks the packaging bags into the storage space and the second pick-and-place component affixes the labels to the packaging bags. The positioning module includes a movable baffle with a through clearance hole. The first pick-and-place component and the second pick-and-place component can pass through the clearance hole. The baffle can abut against the packaging bag from the side of the storage space near the storage opening and push the packaging bag over the limiting component along the first stacking direction, so that the packaging bag is located between the first elastic member and the limiting component.

[0005] In some embodiments, the first stacking direction is the length direction of the storage space and extends horizontally, and the top side of the storage space is open.

[0006] In some embodiments, the baffle moves in a vertical direction, and the bottom side of the clearance hole opens to form an opening.

[0007] In some embodiments, the positioning module includes a first pressure plate that can move in a vertical direction, the first pressure plate being located above the storage module, and the top side of the packaging bag being able to abut against the first pressure plate in a vertical direction.

[0008] In some embodiments, the positioning module includes two second pressure plates that can move horizontally. The second pressure plates are located on both sides of the storage module along the width direction, and the portion of the packaging bag that is higher than the inner wall of the storage space can abut against the second pressure plates horizontally.

[0009] In some embodiments, the limiting component includes a reset member and a rotatable stop plate. The stop plate is disposed on the horizontal sidewall of the storage space near the storage opening and extends vertically. The stop plate includes a stop position and a clearance position. The stop plate rotates to the clearance position in a direction away from the storage opening, so that the packaging bag moves from the side of the stop plate near the storage opening along a first stacking direction past the stop plate to the side away from the storage opening. The reset member drives the stop plate to rotate to the stop position in a direction toward the storage opening, so that the packaging bag on the side of the stop plate away from the storage opening abuts against the stop plate along the first stacking direction.

[0010] In some embodiments, the labeling device includes a first drive module that drives the positioning module to move along a first stacking direction, so that the baffle pushes the packaging bag along the first stacking direction and pushes the stop plate to rotate in a direction away from the receiving opening.

[0011] In some embodiments, the labeling device includes a label supply module for supplying labels, a bag supply module for supplying packaging bags, and a second drive module, the second drive module driving the labeling module to move, and the label supply module, the bag supply module, and the storage module being arranged along the moving direction of the labeling module.

[0012] In some embodiments, the bag supply module has a bagging space for stacking packaging bags. The top side of the bagging space is open. The bagging space has a bag-taking opening that extends along a second stacking direction on one side near the labeling module. The other side has a second elastic member that can extend and retract along the second stacking direction. The packaging bag is sandwiched between the inner wall of the bagging space near the labeling module and the second elastic member along the second stacking direction. The labeling device includes a third drive module that drives the first picking and placing component to move in the up and down direction. The top side of the bag-taking opening is open, and the first picking and placing component can pass through the bag-taking opening along the second stacking direction.

[0013] In some embodiments, the label supply module includes a raw material roller for holding a strip with a label attached, a waste roller for winding the strip, a peeling block, and a drive unit. The peeling block extends axially along the raw material roller, and the raw material roller, the waste roller, and the peeling block are arranged in parallel. The peeling block has a peeling arc surface on the side opposite to the waste roller and the peeling block. The radius of the arc of the peeling arc surface is smaller than the minimum bendable radius of the label and larger than the maximum bendable radius of the strip. The drive unit is driven to the waste roller to drive the waste roller to rotate.

[0014] In some embodiments, the label supply module includes a support block, and the support block, the raw material roller, the waste roller and the peeling block are all arranged in parallel. The support block is located on the side facing the peeling arc surface, and the distance between the support block and the peeling block is smaller than the size of the label.

[0015] The labeling device in this embodiment of the invention automates the labeling process of packaging bags through a labeling module, a storage module, and a positioning module. By setting a movable baffle, on the one hand, the baffle can replace the first pick-and-place component to constrain the position of the packaging bag, thereby facilitating the second pick-and-place component to attach the label to the packaging while reducing the probability of motion interference between the first and second pick-and-place components during movement, and facilitating the optimization of the positional layout of the first and second pick-and-place components; on the other hand, the baffle pushes the packaging bag past the limiting component, thereby enabling the labeled packaging bag to enter between the limiting component and the first elastic member, thus restricting the position of the labeled packaging bag within the storage space.

[0019] This invention provides a labeling device, see below. Figures 1 to 4 The labeling device is used to affix labels to packaging bags 90. The labeling device includes a labeling module 10, a storage module 20, and a positioning module 30.

[0020] The labeling module 10 includes a first pick-and-place component 11 for picking up and placing packaging bags 90 and a second pick-and-place component 12 for picking up and placing labels.

[0021] The storage module 20 includes a storage space 20a for stacking packaging bags 90. One side of the storage space 20a is open along a first stacking direction to form a storage opening 20a, and the other side has a first elastic member 21 that can move along the first stacking direction. A limiting component 22 is provided on the side of the storage space 20a near the storage opening 20a. By restricting the movement of the packaging bags 90 through the inner wall of the storage space 20a, the labeled packaging bags 90 are neatly stacked in the storage space 20a, facilitating subsequent packaging operations.

[0022] Understandably, the number of stacked packaging bags 90 within the storage space 20a varies, and the dimensions of the stacked packaging bags 90 along the first stacking direction also differ. By moving the first elastic member 21 along the first stacking direction, the distance between the first elastic member 21 and the limiting component 22 along the first stacking direction is adapted to the dimensions of the stacked packaging bags 90 along the first stacking direction. This ensures that the stacked packaging bags 90 are sandwiched between the first elastic member 21 and the limiting component 22 along the first stacking direction, maintaining a stable position along the first stacking direction. Simultaneously, by having the limiting component 22 abut against the packaging bag 90 on the side facing away from the storage opening 20a, the probability of the packaging bag 90 falling out of the storage space 20a through the storage opening 20a is reduced.

[0023] The labeling module 10 is located on the side of the storage space 20a along the first stacking direction near the storage opening 20a. Both the first pick-and-place component 11 and the second pick-and-place component 12 can move towards the storage space 20a, so that the first pick-and-place component 11 stacks the packaging bag 90 into the storage space 20a, and the second pick-and-place component 12 affixes the label to the packaging bag 90. Specifically, the first pick-and-place component 11 places the obtained packaging bag 90 into the storage space 20a through the storage opening 20a, and then the second pick-and-place component 12 affixes the obtained label through the storage opening 20a to the side of the packaging bag 90 opposite to the first elastic member 21, thereby completing the labeling operation.

[0024] The positioning module 30 includes a movable baffle 31 with a through clearance hole 31a. The second pick-and-place component 12 can pass through the clearance hole 31a so that the second pick-and-place component 12 can pass through the clearance hole 31a to attach the acquired label to the side of the packaging bag 90 away from the first elastic member 21 via the storage opening 20a.

[0025] The baffle 31 can abut against the packaging bag 90 from the side of the storage space 20a near the storage opening 20a. The clearance hole 31a can reduce the probability that the baffle 31 will directly press against the product in the packaging bag 90, and reduce the probability of product damage caused by the force exerted by the baffle 31 on the product in the packaging bag 90.

[0026] By abutting the baffle 31 against the packaging bag 90 along the first stacking direction, the packaging bag 90 fed by the first pick-and-place component 11 can be restricted between the baffle 31 and the limiting component 22 along the first stacking direction, thereby constraining the position of the packaging bag 90 along the first stacking direction, so that the first pick-and-place component 11 can be separated from the packaging bag 90 and avoid interference between the second pick-and-place component 12 and the first pick-and-place component 11 during the labeling process.

[0027] The limiting component 22 defines the position of the packaging bag 90 in the storage space 20a, which makes it easier to define the position of the first picking and placing component 11 each time it places the packaging bag 90 and the position of the second picking and placing component 12 each time it affixes the label. This helps to simplify the procedure for controlling the movement of the first picking and placing component 11 and the second picking and placing component 12.

[0028] The baffle 31 pushes the packaging bag 90 past the limiting component 22 along the first stacking direction, so that the packaging bag 90 is located between the first elastic member 21 and the limiting component 22, so that the packaged bag 90, which has been labeled, can be clamped between the first elastic member 21 and the limiting component 22 along the first stacking direction to achieve the purpose of fixing its position.

[0029] The labeling device in this embodiment of the invention automates the labeling process of the packaging bag 90 through the labeling module 10, the storage module 20, and the positioning module 30. By setting a movable baffle 31, on the one hand, the baffle 31 can replace the first pick-and-place component 11 to constrain the position of the packaging bag 90, thereby facilitating the second pick-and-place component 12 to attach the label to the packaging while reducing the probability of motion interference between the first pick-and-place component 11 and the second pick-and-place component 12 during movement, and facilitating the optimization of the positional layout of the first pick-and-place component 11 and the second pick-and-place component 12; on the other hand, the baffle 31 pushes the packaging bag 90 past the limiting component 22 to achieve the purpose of moving the labeled packaging bag 90 between the limiting component 22 and the first elastic member 21, thereby restricting the position of the labeled packaging bag 90 within the storage space 20a.

[0030] Understandably, the working steps of each module in the labeling equipment are not limited and can be flexibly arranged according to the specific shape of the packaging bag 90, the specific shape of the label, and the activity mode of each component.

[0031] For example, the specific working steps of the labeling equipment are as follows: S10: Control the first pick-and-place component 11 to place the packaging bag 90 into the storage space 20a through the storage opening 20a, and position the packaging bag 90 on the side of the limiting component 22 facing the storage opening 20a; S11: The control baffle 31 moves to the side of the packaging bag 90 away from the limiting component 22 and fits against the packaging bag 90; S12: Control the first pick-and-place component 11 to detach from the packaging bag 90 and leave the storage space 20a; S13: Control the second pick-and-place component 12 to pass the label through the clearance hole 31a and attach it to the side of the packaging bag 90 facing the storage opening 20a; S14: Control the second pick-and-place component 12 to detach from the label and leave the storage space 20a; S15: Control the baffle 31 to move to push the packaging bag 90 past the limiting component 22 along the first stacking direction; S16: Control the baffle 31 to move away from the storage space 20a.

[0032] Repeat steps S10 to S16 continuously to achieve the process of continuously labeling the packaging bag 90.

[0033] The specific structure of the first elastic element 21 is not limited. For example, the first elastic element 21 includes a first push block and a first spring that can extend and retract along the first stacking direction. One end of the first spring along the extension and retraction direction abuts against the inner wall of the storage space 20a on the side away from the storage opening 20a, and the other end is connected to the first push block. The first push block abuts against the packaging bag 90.

[0034] It is understood that the labeling equipment includes a control module, which is electrically connected to the labeling module 10, the storage module 20, and the positioning module 30 respectively. The control module stores a control program. When the control program is executed, the control module sends control commands to the labeling module 10, the storage module 20, and the positioning module 30 to enable the labeling equipment to complete the predetermined work steps and realize the automated operation of the labeling equipment.

[0035] The specific type of control module is not limited, such as industrial PC, PLC (Programmable Logic Controller), etc.

[0036] The control module includes a touch screen, which displays various parameters and control buttons during the labeling process. Operators can obtain the current working status of the labeling equipment from the touch screen and issue control commands to the control module to control other modules.

[0037] Understandably, the specific arrangement and structure of the storage module 20 facilitates the stacking of packaging bags 90 in the storage space 20a.

[0038] In some embodiments, see Figure 4 The first stacking direction is along the length of the storage space 20a, so as to increase the number of packaging bags 90 that the storage space 20a can hold.

[0039] In some embodiments, see Figure 4The first stacking direction extends horizontally so that the packaging bags 90 in the storage space 20a can be supported by the bottom wall of the storage space 20a in the vertical direction under the action of gravity. This not only restricts the range of movement of the packaging bags 90 in the storage space 20a, but also reduces the probability of the stacked packaging bags 90 tipping over.

[0040] The horizontal direction is perpendicular to the vertical direction.

[0041] Understandably, the structure of the storage module 20 makes it easy for staff to remove the labeled packaging bags 90.

[0042] Specifically, see Figure 4 The top of the storage space 20a is open so that staff can directly observe the stacking of the packaging bags 90 and facilitate staff to organize the packaging bags 90 in the storage space 20a and take out the labeled packaging bags 90.

[0043] Understandably, during the process of the baffle 31 moving to abut against the packaging bag 90, it is necessary to reduce indirect contact between the baffle 31 and the product contained in the packaging bag 90 in order to reduce the adverse effects on the product.

[0044] In some embodiments, see Figure 3 The baffle 31 moves in the vertical direction, and the bottom side of the clearance hole 31a opens to form an opening. This reduces the probability of friction between the baffle 31 and the part of the packaging bag 90 containing the product as the baffle 31 moves downward and comes into contact with the packaging bag 90. This reduces the effect of the baffle 31 on the product and provides a certain degree of protection for the product.

[0045] The specific method by which the baffle 31 moves in the vertical direction is not limited; for example, see [reference needed]. Figure 3 The positioning module 30 includes a first driving device 34, the driving end of the first driving device 34 is connected to the baffle 31 to drive the baffle 31 to move in the up and down direction.

[0046] The specific type of the first drive device 34 is not limited, such as a cylinder, an electric cylinder, etc.

[0047] In some embodiments, the positioning module 30 includes a linear guide rail extending in the vertical direction, and a baffle 31 is slidably disposed on the linear guide rail to constrain the movement trajectory of the baffle 31 in the vertical direction and reduce friction.

[0048] Understandably, after the baffle 31 pushes the packaging bag 90 past the limiting component 22, it will cause the packaging bag 90 to exert a force along the first stacking direction on the packaging bag 90 already stacked in the storage space 20a, thereby creating the risk that the stacked packaging bag 90 will be squeezed and squeezed out of the opening of the storage space 20a.

[0049] In some embodiments, see Figure 3 The positioning module 30 includes a first pressure plate 32 that can move vertically. The first pressure plate 32 is located above the storage module 20, and the top side of the packaging bag 90 can abut against the first pressure plate 32 vertically. By abutting against the packaging bag 90 vertically, the vertical movement tendency of the packaging bag 90 is restricted, thereby reducing the risk that the stacked packaging bags 90 will be squeezed and squeezed out of the opening of the storage space 20a.

[0050] The specific method for moving the first pressure plate 32 in the vertical direction is not limited. For example, the positioning module 30 includes a second driving device 35, and the driving end of the second driving device 35 is connected to the first pressure plate 32 to drive the first pressure plate 32 to move in the vertical direction.

[0051] The specific type of the second drive device 35 is not limited, such as a cylinder, electric cylinder, etc.

[0052] The baffle 31 and the first pressure plate 32 are driven by different driving devices to move vertically at different times. For example, after the first pressure plate 32 moves downward under the drive of the second driving device 35 and comes into contact with the packaging bag 90, the baffle 31 moves downward under the drive of the second driving device 35 to prevent the packaging bag 90 from being squeezed out of the storage space 20a by the baffle 31 and then squeezed downward by the first pressure plate 32, thus avoiding damage.

[0053] It is understandable that, in the projection along the vertical direction, the projection of the first pressure plate 32 and the projection of the range of motion of the baffle 31 pushing the packaging bag 90 are independent of each other, so as to avoid motion interference between the first pressure plate 32 and the baffle 31.

[0054] In some embodiments, see Figure 4 The inner wall of the storage space 20a in the horizontal direction is lower than the height of the packaging bag 90 in the vertical direction, so as to reduce the contact area between the packaging bag 90 and the storage space 20a, thereby reducing the friction force on the packaging bag 90 during movement and reducing the probability of the packaging bag 90 being damaged due to friction.

[0055] Understandably, since the inner wall of the storage space 20a in the horizontal direction is lower than that of the packaging bag 90, the constraint on the packaging bag 90 is reduced. The packaging bag 90 placed in the storage space 20a is prone to tilting under the squeezing action of the baffle 31.

[0056] In some embodiments, see Figure 3The positioning module 30 includes two horizontally movable second pressure plates 33. The second pressure plates 33 are located on both sides of the storage module 20 along the width direction. The portion of the packaging bag 90 that is higher than the inner wall of the storage space 20a can abut against the second pressure plates 33 horizontally. By abutting against the packaging bag 90 along the width direction with the second pressure plates 33, the movement tendency of the packaging bag 90 in the width direction is restricted, thereby reducing the risk of the packaging bag 90 tilting under the squeezing action of the baffle 31.

[0057] The specific method for moving the second pressure plate 33 in the horizontal direction is not limited. For example, the positioning module 30 includes a third driving device 36, and the driving end of the third driving device 36 is connected to the second pressure plate 33 to drive the second pressure plate 33 to move in the vertical direction.

[0058] The specific type of the third drive device 36 is not limited, such as a gripper cylinder.

[0059] The specific structural form of the limiting component 22 is not limited.

[0060] In some embodiments, see Figure 4 The limiting component 22 includes a reset member and a rotatable stop plate 221. The stop plate 221 is disposed on the side wall of the storage space 20a near the storage opening 20a in the horizontal direction and extends in the vertical direction. The stop plate 221 includes a stop position and a clearance position. The stop plate 221 rotates to the clearance position in the direction away from the storage opening 20a, so that the packaging bag 90 moves from the side of the stop plate 221 near the storage opening 20a along the first stacking direction past the stop plate 221 to the side away from the storage opening 20a. The reset member drives the stop plate 221 to rotate to the stop position in the direction toward the storage opening 20a, so that the packaging bag 90 on the side of the stop plate 221 away from the storage opening 20a abuts against the stop plate 221 along the first stacking direction.

[0061] When the stop plate 221 is in the stop position, the stop plate 221 can only rotate in the direction away from the storage opening 20a; when the stop plate 221 is in the avoidance position, the stop plate 221 can only rotate in the direction toward the storage opening 20a.

[0062] The baffle 31 pushes the packaging bag 90 along the first stacking direction, causing the packaging bag 90 to abut against the side of the stop plate 221 facing the storage opening 20a. This pushes the stop plate 221 from the stopped position to the avoidance position in the direction away from the storage opening 20a. During this process, the packaging bag 90 continues to move along the first stacking direction under the push of the baffle 31 and passes over the stop plate 221. After the baffle 31 disengages from the storage space 20a and the stop plate 221 returns from the avoidance position to the stopped position, the first elastic member 21 pushes the stacked packaging bag 90 toward the storage opening 20a until the packaging bag 90 is sandwiched between the side of the stop plate 221 away from the storage opening 20a and the first elastic member 21. By rotating the stop plate 221, it is easy to reduce the resistance encountered by the baffle 31 in pushing the packaging bag 90 over the limiting component 22, and also achieve the purpose of stacking and fixing the labeled packaging bag 90 in the storage space 20a.

[0063] The specific form of the reset element is not limited. For example, the reset element is a torsion spring, with one end of the torsion spring fixed to the stop plate 221 and the other end fixed to the inner wall of the storage space 20a.

[0064] The method by which the baffle pushes the packaging bag 90 degrees is not limited.

[0065] For example, see Figure 3 The labeling equipment includes a first drive module 40, which drives the positioning module 30 to move along a first stacking direction, so that the baffle 31 pushes the packaging bag 90 along the first stacking direction and pushes the stop baffle 221 to rotate in a direction away from the storage opening 20a.

[0066] After the baffle 31 moves downward to the lowest position, the first drive module 40 drives the positioning module 30 to move away from the storage opening 20a along the first stacking direction, so that the baffle 31 abuts against the packaging bag 90 along the first stacking direction and pushes the packaging bag 90 away from the storage opening 20a along the first stacking direction until the packaging bag 90 passes the limiting component 22. After the baffle 31 moves upward to get out of the storage space 20a, the first drive module 40 drives the positioning module 30 to move closer to the storage opening 20a along the first stacking direction to the initial position, and so on.

[0067] In some embodiments, see Figure 3 The first drive module 40 includes a mounting beam 41 and a sixth drive device 42. The sixth drive device 42 is located below the storage module 20. The mounting beam 41 is connected to the drive part of the drive module and spans above the storage module 20, thereby improving the structural stability of the mounting beam 41 and making the baffle 31 more stable as it moves with the mounting beam 41. The baffle 31 is located on the side of the mounting beam 41 near the storage opening 20a.

[0068] The specific type of the sixth drive unit 42 is not limited, such as a linear module.

[0069] The specific methods by which the first pick-and-place component 11 and the second pick-and-place component 12 pick up and place the packaging bag 90 and the label are not limited.

[0070] In some embodiments, see Figure 2 The first pick-and-place assembly 11 includes a fourth driving device 111 and a first vacuum suction cup 112. The first vacuum suction cup 112 is located at the end of the fourth driving device 111 facing the storage opening 20a. The fourth driving device 111 is used to drive the first vacuum suction cup 112 to extend and retract along a first stacking direction. The first vacuum suction cup 112 can generate suction force to adsorb the packaging bag 90. After the first pick-and-place assembly 11 places the packaging bag 90 into the storage space 20a, it controls the first vacuum suction cup 112 to break the vacuum, thereby separating the first vacuum suction cup 112 from the packaging bag 90. The use of the first vacuum suction cup 112 can play a buffering role during the pick-and-place process of the packaging bag 90, reducing the probability of the first pick-and-place assembly 11 damaging the packaging bag 90 during the pick-and-place process.

[0071] The number of first vacuum suction cups 112 is not limited. For example, there are three first vacuum suction cups 112 arranged in an isosceles triangle to improve the stability of the first vacuum suction cups 112 in the process of adsorbing the packaging bag 90.

[0072] In some embodiments, see Figure 2 The second pick-and-place assembly 12 includes a fifth driving device 121 and a second vacuum suction cup 122. The second vacuum suction cup 122 is located at the end of the fifth driving device 121 facing the receiving opening 20a. The fifth driving device 121 drives the second vacuum suction cup 122 to extend and retract along the first stacking direction. The second vacuum suction cup 122 can generate suction force to adsorb the label. After the second pick-and-place assembly 12 adheres the label to the packaging bag 90, it controls the vacuum of the second vacuum suction cup 122 to break, causing the second vacuum suction cup 122 to separate from the label. The use of the second vacuum suction cup 122 can play a buffering role during the label pick-and-place process, reducing the probability of the second pick-and-place assembly 12 damaging the label during the process.

[0073] It is understood that the labeling module 10 includes a vacuum generator and a vacuum gauge. The vacuum generator is connected to the first vacuum suction cup 112 and the second vacuum suction cup 122 through vacuum pipelines, so that the first vacuum suction cup 112 and the second vacuum suction cup 122 generate negative pressure and break the vacuum. The vacuum gauge is configured in the vacuum pipeline to display the current pressure status in the vacuum pipeline.

[0074] In some embodiments, the specific working steps of the labeling equipment are as follows: S200: Control the fourth drive device 111 to extend towards the storage opening 20a along the first stacking direction, so that the first vacuum suction cup 112 puts the adsorbed packaging bag 90 into the storage space 20a through the storage opening 20a, and places the packaging bag 90 on the side of the baffle 31 facing the storage opening 20a. S201: Control the second drive device 35 to drive the first pressure plate 32 to move downward so that the top side of the packaging bag 90 abuts against the first pressure plate 32 in the vertical direction; S202: Control the third drive device 36 to drive the second pressure plate 33 to move horizontally toward the packaging bag 90, so that the packaging bag 90 and the second pressure plate 33 abut horizontally; S203: Control the first driving device 34 to drive the baffle 31 to move downward to the preset blocking position; S204: Control the first vacuum suction cup 112 to break the vacuum, and control the fourth drive device 111 to retract from the storage port 20a along the first stacking direction; S205: The third drive module 13 drives the first pick-and-place component 11 and the second pick-and-place component 12 to move upward together to the preset labeling position; S206: Control the fifth drive device 121 to extend towards the storage opening 20a along the first stacking direction until the second vacuum suction cup 122 adheres the adsorbed label to the packaging bag 90. S207: Control the second vacuum suction cup 122 to break the vacuum, and control the fifth drive device 121 to retract from the storage port 20a along the first stacking direction; S208: Control the third drive device 36 to drive the second pressure plate 33 to move horizontally away from the packaging bag 90 to the third initial position; S209: Control the first drive module 40 to move away from the storage opening 20a so that the baffle 31 pushes the packaging bag 90 over the stop plate 221; S210: Control the first driving device 34 to drive the baffle 31 to move upward to the first initial position, control the second driving device 35 to drive the first pressure plate 32 to move upward to the second initial position, and control the first driving module 40 to drive the positioning module 30 to move towards the direction close to the storage port 20a to the fourth initial position.

[0075] The labeling equipment includes a label supply module 80 for supplying labels and a bag supply module 50 for supplying packaging bags 90. The arrangement of the label supply module 80 and the bag supply module 50 facilitates the labeling module 10 in picking up and placing the packaging bags 90 and labels.

[0076] In some embodiments, see Figure 2The labeling equipment includes a second drive module 70, which drives the labeling module 10 to move. A label supply module 80, a bag supply module 50, and a storage module 20 are arranged along the moving direction of the labeling module 10. The moving direction of the labeling module 10 includes a label supply position, a bag supply position, and a labeling position. When the second drive module 70 drives the labeling module 10 to the label supply position, the labeling module 10 obtains a label from the label supply module 80. When the second drive module 70 drives the labeling module 10 to the bag supply position, the labeling module 10 obtains a packaging bag 90 from the label supply module 80. When the second drive module 70 drives the labeling module 10 to the labeling position, the labeling module 10 places the packaging bag 90 into the storage module 20 and affixes the label to the packaging bag 90. By continuously changing the position of the labeling module 10 driven by the second drive module 70, the labeling equipment can continuously complete the steps of picking up the label, picking up the packaging bag 90, and labeling the packaging bag 90, thereby improving production efficiency.

[0077] The second drive module 70 can drive the labeling module 10 in any way, for example, by driving the labeling module 10 to reciprocate in a straight line; or by driving the labeling module 10 to rotate in a circle.

[0078] The specific type of the second drive module 70 is not limited, such as a linear module, a DD (direct driver) motor turntable, etc.

[0079] The specific structure of the bag supply module 50 is not limited.

[0080] For example, see Figure 5 The bag supply module 50 includes a bagging space 50a for stacking packaging bags 90. The top of the bagging space 50a is open. A bag-retrieving opening 50b extending along a second stacking direction is located on the side of the bagging space 50a near the labeling module 10. A second elastic member 51, which can extend and retract along the second stacking direction, is located on the other side of the bagging space 50a. The packaging bag 90 is sandwiched between the inner wall of the bagging space 50a near the labeling module 10 and the second elastic member 51 along the second stacking direction. That is, in the projection along the second stacking direction, the projection of the bag-retrieving opening 50b is within the projection range of the bagging space 50a. The second elastic member 51 can apply a force towards the bag-retrieving opening 50b to the packaging bags 90 stacked in the bagging space 50a, ensuring that the stacked packaging bags 90 always adhere to the inner wall of the bagging space 50a near the labeling module 10, so that the labeling module 10 can continuously retrieve packaging bags 90 from the same position each time.

[0081] In some embodiments, see Figure 2The labeling device includes a third drive module 13, which drives a first pick-and-place component 11 to move vertically. The top side of the bag-taking opening 50b is open, and the first pick-and-place component 11 can pass through the bag-taking opening 50b along a second stacking direction. The first pick-and-place component 11 enters the bagging space 50a through the bag-taking opening 50b and picks up the bag 90 closest to the bag-taking opening 50b among the stacked bags 90. The third drive module 13 drives the first pick-and-place component 11 to move upward, so that the bag 90 picked up by the first pick-and-place component 11 is removed from the bagging space 50a from the open portion on the top side of the bagging space 50a.

[0082] The specific structure of the second elastic member 51 is not limited. For example, the second elastic member 51 includes a second push block and a second spring that can extend and retract along the second stacking direction. One end of the second spring abuts against the inner wall of the storage space 20a away from the storage opening 20a along the extension and retraction direction, and the other end is connected to the second push block. The second push block abuts against the packaging bag 90.

[0083] The specific type of the third drive module 13 is not limited, such as a linear module.

[0084] In some embodiments, the first stacking direction is parallel to the second stacking direction to simplify the working steps of the first pick-and-place component 11 and the second pick-and-place component 12.

[0085] In some embodiments, referring to 2, the first pick-and-place component 11 and the second pick-and-place component 12 are both disposed on the third drive module 13 so that the driver moves together in the up-down direction, thereby separating the steps of the first pick-and-place component 11 placing the packaging bag 90 into the storage space 20a and the second pick-and-place component 12 attaching the label to the packaging, so as to avoid interference between the two movements.

[0086] The specific type of the supplied module 80 is not limited.

[0087] For example, see Figure 6 and Figure 7 The label-supplying module 80 includes a raw material roller 81 for holding a strip 91 with a label attached, a waste roller 82 for winding the strip 91, a peeling block 83, and a drive unit 84. The peeling block 83 extends along the axial direction of the raw material roller 81. The raw material roller 81, waste roller 82, and peeling block 83 are arranged in parallel. The peeling block 83 has a peeling arc surface 83a on the side away from the waste roller 82 and the peeling block 83. The radius of the arc of the peeling arc surface 83a is smaller than the minimum bendable radius of the label and larger than the maximum bendable radius of the strip 91. The drive unit 84 is drivenly connected to the waste roller 82 to drive the waste roller 82 to rotate.

[0088] Both the raw material roller 81 and the waste roller 82 are rotatable. The labeled strip 91 is drawn from the raw material roller 81 until it comes into contact with the peeling arc surface 83a of the peeling block 83. Because both the waste roller 82 and the peeling block 83 are located on the side opposite to the contact surface between the peeling block 83 and the strip 91, the extension direction of the strip 91 bends after passing the peeling arc surface 83a. The minimum bendable radii of the strip 91 and the label are different, and the cross-sectional radius of the peeling block 83 is smaller than the minimum bendable radius of the label but larger than the maximum bendable radius of the strip 91. This causes the label to peel off the strip 91 after it passes over the surface of the peeling block 83. The strip 91 continues to extend onto the waste roller 82 and is wound up as the waste roller 82 rotates. As the waste roller 82 rotates, the labeled strip 91 drawn from the raw material roller 81 continuously passes over the surface of the peeling block 83 and peels off the label, thus achieving the purpose of continuously providing labels. The cooperation of the raw material roller 81, waste roller 82 and peeling block 83 reduces the friction of the labels and the noise generated by the rotation is small. The speed of label supply can be adjusted by adjusting the rotation speed of the waste roller 82, which is conducive to adapting to different label supply speed requirements.

[0089] It is understandable that after the label is separated from the conveyor belt 91, the second pick-and-place component 12 picks up the label to avoid the label falling off after it is completely separated from the conveyor belt 91, which would prevent the second pick-and-place component 12 from picking up the label.

[0090] The specific type of the drive component 84 is not limited, such as a stepper motor.

[0091] In some embodiments, see Figure 6 and Figure 7 The label supply module 80 includes a support block 85. The support block 85, raw material roller 81, waste roller 82, and peeling block 83 are all arranged in parallel. The support block 85 is located on the side facing the peeling arc surface 83a, and the distance between the support block 85 and the peeling block 83 is smaller than the size of the label. The support block 85 can support the labels peeled from the material strip 91 on the peeling block 83. On the one hand, it reduces the risk of the peeled labels falling off; on the other hand, it ensures that the labels are in approximately the same position after each peeling, which is beneficial for the second pick-and-place component 12 to pick up the labels from the same position each time.

[0092] In some embodiments, see Figure 7 The standard supply module 80 includes several tension rollers 86. The tension rollers 86, support blocks 85, raw material rollers 81, waste rollers 82 and stripping blocks 83 are all arranged in parallel. At least one tension roller 86 is arranged between the waste rollers 82 and the stripping blocks 83, and at least one tension roller 86 is arranged between the raw material rollers 81 and the stripping blocks 83, so as to reduce the probability of problems such as entanglement and twisting of the material strip 91 due to gravity.
