In the production of films, packaging of the films is a very important link. In the prior art, the packaging of the membrane is completed by manpower, and the conditions of low efficiency, poor packaging quality, non-uniform packaging quality, easy pollution of the membrane and the like exist in the manual packaging. One difficulty in achieving automatic packaging of films is that labels cannot be automatically attached, and labels attached to packages generally contain product information such as product lots, models, etc., and therefore, labeling is a necessary process for product management. The existing label attaching work is completed manually, and the problems of low efficiency, easy misplacement, poor attaching effect and the like exist, and the problem that the attaching effect is poor is mainly caused by non-uniform attaching positions and attaching directions, so that the problem that the products are difficult to identify and manage in batches is solved. In addition, because the film packaging belt is large in size and soft in material, if the film is automatically packaged, the opening of the packaging bag is required to be upward, and therefore the gesture of the label is required to be matched with the gesture of the packaging bag during labeling. Therefore, there is a need for an apparatus that can efficiently and accurately automatically label film packages.

In view of the above technical problems, the present utility model provides a labeling apparatus for a packaging line, comprising: the label printing mechanism is used for printing labels and conveying the printed labels to a label outlet; the label bearing mechanism is arranged adjacent to the label outlet, and is used for bearing the label at the label outlet and conveying the label to a label taking position; the labeling mechanism comprises a label taking and pasting component and a driving component which is in transmission connection with the label taking and pasting component, wherein the driving component is used for driving the label taking and pasting component to move to the label taking and pasting position so as to pick up the label, driving the label taking and pasting component to turn over so as to face a packaging bag positioned at the label pasting position, and driving the label taking and pasting component to transport the label to the label pasting position so as to finish labeling; and the limiting mechanism is arranged at the labeling position and is positioned at one side of the packaging bag, which is away from the labeling component, and is used for preventing the packaging bag from moving along the direction away from the labeling component when the labeling component labels.

Therefore, automatic labeling can be efficiently and accurately realized, and labeling efficiency and labeling quality are improved.

The following describes implementation details of the feeding device for the packaging line of the present utility model in detail, and the following description is provided only for the convenience of understanding, and is not necessary to implement the present embodiment.

As shown in fig. 1 and 2, the labeling apparatus for a packaging line includes: the label printing mechanism 100 is used for printing labels L and conveying the printed labels L to the label outlet 110. A label carrying mechanism 200 is disposed adjacent to the label outlet 110, and the label carrying mechanism 200 is configured to receive the label L at the label outlet 110 and transport the label L to a label picking position. The labeling mechanism 300 comprises a labeling component 310 and a driving component 320 in transmission connection with the labeling component 310, wherein the driving component 320 is used for driving the labeling component 310 to move to a labeling position to pick up the label L, driving the labeling component 310 to turn over to face a packaging bag P positioned at the labeling position, and driving the labeling component 310 to convey the label L to the labeling position to finish labeling. And the limiting mechanism 400 is arranged at the labeling position, the limiting mechanism 400 is positioned at one side of the packaging bag P, which is away from the labeling component 310, and the limiting mechanism 400 is used for preventing the packaging bag P from moving along the direction away from the labeling component 310 when the labeling component 310 is labeled.

In the present utility model, the label printing mechanism 100 is a label printer, and the specific model of the label printer may be arbitrarily selected according to the actual requirement, which is not specifically limited herein.

Referring to fig. 3, in some embodiments, the driving assembly 320 includes a mounting frame 321 and a turnover driving structure 322 disposed on the mounting frame 321, one end of the turnover driving structure 322 is fixedly connected to the mounting frame 321, and the other end of the turnover driving structure 322 is hinged to the label picking and attaching assembly 310. The label picking and attaching assembly 310 is connected with the mounting frame 321 in a reversible manner, and the turnover driving structure 322 drives the label picking and attaching assembly 310 to turn to the label picking position to pick up the label L, and drives the label picking and attaching assembly 310 to turn the label L towards the packaging bag P located at the label attaching position.

Specifically, after the label carrying mechanism 200 moves the label L to the label picking position, the overturning driving structure 322 drives the label picking assembly 310 to overturn towards the label on the label carrying mechanism 200, the label picking assembly 310 finishes the action of picking the label L, and then, the overturning driving structure 322 drives the label picking assembly 310 to overturn towards the packaging bag P located at the label picking position again, so that the gesture of the label L and the gesture of the packaging bag P are matched for labeling.

Referring to fig. 4, in some embodiments, the overturning driving structure 322 includes an overturning cylinder 322a and a hinge 322b, one end of the overturning cylinder 322a is connected and fixedly connected to the mounting frame 321, a piston of the overturning cylinder 322a is telescopic along a vertical direction and is fixedly connected to the hinge 322b, and the hinge 322b is fixedly connected to the label picking and attaching assembly 310. Wherein the piston of the reversing cylinder 322a is extended to drive the label picking assembly 310 to reverse downward to pick up the label L on the label bearing mechanism 200. The piston of the reversing cylinder 322a is retracted to drive the label picking and applying assembly 310 upward to reverse the label L toward the package P in the labeling position.

Specifically, the piston of the overturning cylinder 322a extends downward to push the label picking and sticking assembly 310 to overturn downward, and at this time, the label picking and sticking assembly 310 faces the label L on the label bearing mechanism 200, and performs label picking. After the label is taken out, the cylinder of the turning cylinder 322a is retracted upwards, and the label taking and attaching assembly 310 is pulled to turn upwards, at this time, the label taking and attaching assembly 310 faces the packaging bag P located at the label attaching position, and the posture of the label L on the label taking and attaching assembly 310 is matched with the posture of the packaging bag P located at the label attaching position. For example, the label L and the package P are parallel to each other (the thickness direction of both are the same), and the adhesive surface of the label L faces the package P.

Alternatively, the hinge 322b may be a fish eye bearing, or other hinge that can satisfy the requirement that the label picking and applying assembly 310 be turned under the driving of the turning cylinder 322 a.

Referring to fig. 5, in some embodiments, the labeling assembly 310 includes a turnover member 311 and a vacuum chuck 312 fixed to the turnover member 311, wherein the turnover member 311 is connected with the mounting frame 321 in a turnover manner and is fixedly connected with the hinge member 322b. The vacuum chuck 312 has a vacuum chamber (not shown) and a suction hole 312a, and the suction hole 312a is located at a side of the vacuum chuck 312 facing away from the flip member 311 and communicates with the vacuum chamber.

Further, the label picking device also comprises a vacuum generator (not shown in the figure) and an air duct (not shown in the figure), wherein the vacuum generator is communicated with the vacuum cavity through the air duct, when a label is required to be picked up, the vacuum generator works, vacuum negative pressure is formed inside the air duct and the vacuum cavity, and the suction hole 312a is communicated with the vacuum cavity, so that the suction hole 312a is also negative pressure, and at the moment, the vacuum sucker 312 is close to the label L, the label L is influenced by the negative pressure and is sucked and fixed on the surface of the vacuum sucker 312 by the vacuum sucker 312. When labeling, after the label L is attached to the packaging bag P by the vacuum chuck 312, the vacuum generator breaks the vacuum in the vacuum cavity, so that the negative pressure at the suction hole 312a is relieved, and the label L is not sucked and fixed by the vacuum chuck 312, so that the label L is separated.

In some embodiments, the suction holes 312a may be plural, so that the suction area of the vacuum chuck 312 to the label L may be increased, thereby improving the stability of the vacuum chuck 312 to suction the label L. Preferably, the plurality of adsorption holes 312a may be arranged in an array arrangement.

In some embodiments, a vacuum pressure gauge (also referred to as a vacuum detection gauge, not shown in the figure) may be further provided, where the vacuum detection gauge is connected to the vacuum generator, and is used to detect the working state of the vacuum generator or control the vacuum generator, and through the vacuum detection gauge, an operator can clearly know the vacuum state of the vacuum generator, such as a vacuum (negative pressure) value, etc. More specifically, the vacuum gauge may trigger an alarm when the vacuum condition is abnormal.

In some embodiments, an elastic member (not shown) may be disposed between the overturning member 311 and the vacuum chuck 312, so that when the overturning member 311 overturns and the vacuum chuck 312 takes out the label or pastes the label, the elastic member can play a role of buffering, preventing the vacuum chuck 312 and/or the overturning member 311 from being damaged. For example, when labeling, the vacuum chuck 312 needs to press the package P, and at this time, the elastic member is compressed to play a buffering role.

Optionally, the elastic member may be a rubber pad, a silica gel pad or other cushion pad made of elastic material; alternatively, the elastic member may be a plurality of springs, and the specific arrangement method may be selected by those skilled in the art according to the actual situation, which is not particularly limited herein.

It will be appreciated that when the flipping cylinder 322a drives the flipping member 311 to flip, the distance between the free end of the flipping member 311 and the mounting frame 321 in the horizontal direction is continuously changed, and thus the flipping cylinder 322a may be swingably provided to the mounting frame 321. Thus, when the free end of the turnover member 311 moves, the turnover cylinder 322a may swing synchronously under the interaction with the turnover member 311 to change the included angle between the turnover cylinder 322a and the mounting frame 321, so as to adapt to the change of the horizontal distance between the free end of the turnover member 311 and the mounting frame 321. Meanwhile, since the inversion cylinder 322a has a small range of swing during operation, the expansion and contraction direction of the piston of the inversion cylinder 322a is substantially vertical, allowing a small range of deviation.

Referring again to fig. 3, in some embodiments, the driving assembly 320 further includes an up-down cylinder 323, and a piston of the up-down cylinder 323 is vertically retractable and fixedly connected to the mounting frame 321. Wherein, the piston of the up-down cylinder 323 extends out to drive the mounting frame 321 to drive the label picking and sticking assembly 310 to move downwards to the label picking position to pick up the label L; the piston of the up-down cylinder 323 is retracted, so as to drive the mounting frame 321 to drive the label picking and attaching assembly 310 to move upwards, so as to avoid the label bearing mechanism 200 when the label picking and attaching assembly 310 is overturned.

Specifically, when the label L needs to be sucked, the overturning cylinder 322a drives the overturning piece 311 to overturn downwards, and the piston of the up-down cylinder 323 extends downwards to drive the vacuum chuck 312 to move downwards to the label picking position and suck the label L. Then, the piston of the up-down cylinder 323 is retracted upwards to drive the vacuum chuck 312 to move upwards for a certain distance, and the overturning piece 311 is driven to overturn upwards by the overturning cylinder 322 a. After the vacuum chuck 312 is lifted by the up-down cylinder 323, the overturning cylinder 322a drives the vacuum chuck 312 to overturn, so that the vacuum chuck 312 can be prevented from interfering with the label bearing mechanism 200 during overturning.

In practice, labeling of labels of different specifications may be completed by the telescopic action of the piston of the up-down cylinder 323. Specifically, when the label L with a larger size needs to be attached, the piston of the up-down cylinder 323 retracts upward after the vacuum chuck 312 sucks the label L, so as to drive the vacuum chuck 312 to move upward for a certain distance, and then the overturning cylinder 322a drives the overturning piece 311 to overturn upward, so that the label L faces the packaging bag P; when the label L with a smaller size needs to be attached, the overturning member 311 is driven to overturn upwards by the overturning cylinder 322a, so that after the label L faces the packaging bag P, the piston of the upper and lower cylinders 323 extends downwards for a certain distance, and the labeling position of the label L is lowered. It will be appreciated that the package P has a specific labeling area, and thus the upper and lower cylinders 323 drive the vacuum chuck 312 to rise or fall, and the label L can be aligned with the labeling area of the package P.

Referring to fig. 3 and fig. 6 together, in some embodiments, the driving assembly 320 further includes a first fixing frame 324, a horizontal guide rail 325, and a horizontal driving structure 326, the horizontal guide rail 325 and the horizontal driving structure 326 are both fixed on the first fixing frame 324, the mounting frame 321 is movably disposed on the horizontal guide rail 325, the horizontal driving structure 326 is in transmission connection with the mounting frame 321, the horizontal driving structure 326 drives the mounting frame 321 to drive the label picking assembly 310 to move to the label picking position to pick up the label L, and drives the label picking assembly 310 to move the label L to the label labeling position for labeling. The mounting frame 321 is movably arranged on the horizontal guide rail 325, and the mounting frame 321 is driven to horizontally move by the horizontal driving structure 326, so that the mounting frame 321 drives the vacuum chuck 312 of the label picking and sticking assembly 310 to reciprocate between the label picking position and the label sticking position. The use of the horizontal guide rail 325 makes the movement process of the mounting frame 321 and the vacuum chuck 312 more stable. Specifically, when the label is required to be fetched, the horizontal driving structure 326 drives the mounting frame 321 to horizontally move so as to drive the vacuum chuck 312 to move to the label fetching position, the up-down air cylinder 323 drives the mounting frame 321 to downwardly move so as to enable the vacuum chuck 312 to finish the label fetching action, after that, the up-down air cylinder 323 drives the vacuum chuck 312 to rise to a certain height, and then the overturning air cylinder 322a drives the vacuum chuck 312 to overturn towards the packaging bag P, and then the horizontal driving structure 326 drives the mounting frame 321 to horizontally move so as to drive the vacuum chuck 312 to move towards the packaging bag P so as to finish the label pasting.

Referring again to fig. 6, in some embodiments, the horizontal driving structure 326 includes a horizontal cylinder 326a and a sliding seat 326b, the horizontal cylinder 326a is fixed on the first fixing frame 324, a piston of the horizontal cylinder 326a is telescopic along a horizontal direction and is fixedly connected to the sliding seat 326b, the sliding seat 326b is movably disposed on the horizontal rail 325, and the sliding seat 326b is fixedly connected to the mounting frame 321. Wherein, the piston of the horizontal cylinder 326a extends out to drive the sliding seat 326b to drive the label picking and sticking assembly 310 to move to the label picking position so as to pick up the label L; the piston of the horizontal cylinder 326a is retracted, so as to drive the sliding seat 326b to drive the labeling component 310 to move to the labeling position for labeling.

Specifically, the horizontal rails 325 may be provided in two and parallel to each other, and the horizontal cylinder 326a is provided between the two horizontal rails 325, and the piston of the horizontal cylinder 326a is fixedly connected to the sliding seat 326b. Thus, the two horizontal guide rails 325 can be used to improve the stability of the movement of the label picking and applying assembly 310, and the size of the driving assembly 320 can be reduced.

Alternatively, the angle at which the flipping cylinder 322a drives the flipping member 311 to flip may be 90 ° or other angles. Preferably 90 °, that is, after the label L printed by the label printing mechanism 100 is output from the label outlet 110, the label bearing mechanism 200 receives the label L, and the label L is horizontally placed. When the vacuum chuck 312 picks up the label L, and the overturning cylinder 322a drives the overturning member 311 to overturn by 90 °, the label L is in a vertical state and parallel to the packaging bag P at the labeling position, so that the label L is conveniently attached to the packaging bag P, as shown in fig. 3. Since the motion pattern of the vacuum chuck 312 is fixed and the horizontal movement track is limited by the horizontal guide rail 325, the labeling position and the labeling angle of each of the packing bags P are substantially the same each time the labeling is completed.

In other embodiments, the horizontal cylinder 326a may be replaced with a rotating motor and screw slide drive. Specifically, the rotating motor may be disposed between the two horizontal guide rails 325, the screw rod and the rotating shaft of the rotating motor are coaxially and fixedly connected, the slider is in threaded connection with the screw rod and sleeved on the outer periphery of the screw rod, and the slider is configured to be unable to rotate along with the screw rod, and at the same time, the slider is fixedly connected with the sliding seat 326b. Thus, when the rotating shaft of the rotating motor rotates, the screw rod rotates, and the sliding block is pushed by the threads of the screw rod to horizontally move, so that the sliding seat 326b is driven to horizontally move.

Referring to fig. 7, in some embodiments, the label bearing mechanism 200 includes a support frame 210, a moving assembly 220, and a label bearing plate 230. The moving assembly 220 is fixedly disposed on the supporting frame 210, and the moving assembly 220 is in transmission connection with the label bearing plate 230. The moving assembly 220 drives the label bearing plate 230 to move to the label outlet 110 to receive the label L, and drives the label bearing plate 230 to convey the label L to the label picking position. If the vacuum chuck 312 is made to directly suck the label L at the label outlet 110, the vacuum chuck 312 and the label printer may interfere with each other, so that by providing the moving assembly 220 and the label bearing plate 230, the label L is received at the label outlet 110 by the label bearing plate 230, and the label bearing plate 230 is driven by the moving assembly 220 to move the label L to the label taking position, the vacuum chuck 312 can keep a certain distance from the label printer during label taking, so that interference between the two can be avoided. The support 210 is used to make the label picking position and the height of the label outlet 110 approximately equal, which is advantageous for the configuration of the label picking assembly 310.

Referring again to fig. 7, in some embodiments, the moving assembly 220 includes a cylinder 221, the cylinder 221 is fixed to the supporting frame 210, and a piston of the cylinder 221 is retractable in a horizontal direction and is fixedly connected to the label bearing plate 230. Wherein the piston of the cylinder 221 is retracted to drive the label carrying plate 230 to move to the label outlet 110 to receive the label L; the piston of the cylinder 221 extends out to drive the label carrying plate 230 to move the label L to the label picking position.

In other embodiments, the cylinder 221 may be fixed, and the support frame 210 may be fixed to the piston of the cylinder 221, so that the label bearing plate 230 may be fixed to the support frame 210. When picking up a label, the piston of the cylinder 221 drives the support 210 to drive the label bearing plate 230 to move.

Referring to fig. 8, in some embodiments, the label bearing surface of the label bearing plate 230 is provided with a plurality of grooves 231 to reduce the contact area between the label and the label bearing surface. It will be appreciated that the label L is required to be attached to the package P, so that the vacuum chuck 312 is required to suck the label L, the vacuum chuck 312 is required to suck the front surface of the label L, and the adhesive surface of the label L is directed toward the package P after sucking the label L, so that the adhesive surface of the label L is directed downward when the label L is on the label carrying plate 230, and the front surface of the label L is directed upward for the vacuum chuck 312 to suck. In this case, if the upper surface of the label bearing plate 230 is a plane, when the vacuum chuck 312 moves downward to suck the label L, the adhesive surface is easily stuck to the upper surface of the label bearing plate 230, so that the vacuum chuck 312 cannot suck the label L smoothly, and it is difficult to ensure that the adhesive surface has sufficient adhesiveness even if the label L can be sucked. By providing the label bearing surface of the label bearing plate 230 with a plurality of grooves 231, the contact area between the adhesive surface and the upper surface of the label bearing plate 230 can be reduced, so that the vacuum chuck 312 can more easily suck the label L, and the cleanliness of the adhesive surface can be ensured, thereby ensuring that the adhesive surface has sufficient adhesiveness.

Alternatively, the groove 231 may be a U-shaped groove, a spherical groove, or other grooves, or may be a through hole penetrating the upper and lower surfaces of the label bearing plate 230, which is not limited herein.

Specifically, when the groove 231 is formed as a bar-shaped groove, a portion of the label carrying plate 230 where the bar-shaped groove is not formed may have a plurality of ribs, and when the label L is dropped onto the label carrying plate 230, an upper surface of the plurality of ribs contacts the adhesive surface.

Further, the plurality of ribs are close to one end of the label printer and are provided with inclined surfaces 233, the inclined surfaces 233 extend from the upper surfaces of the ribs to be flush with the bottom surface of the strip-shaped groove, when the label L is output from the label outlet 110, the inclined surfaces 233 can avoid the label L, and meanwhile, a certain guiding effect can be achieved.

Further, the thickness of the label bearing plate 230 at the portion provided with the inclined surface 233 may be reduced relative to other portions, so that when the label bearing plate 230 moves to the label outlet 110 to receive the label L, the portion of the label bearing plate 230 with smaller thickness may extend into the label outlet 110 to receive the label L, so as to avoid the label L falling outside the receiving range of the label bearing plate 230.

It will be appreciated that the label picking and applying assembly 310 may also avoid the label L from adhering to the label bearing plate 230 by vacuum suction of the label L by the vacuum chuck 312. This is because the label L is sucked by using a vacuum negative pressure, and the label L can be sucked and fixed by using the negative pressure when the vacuum chuck 312 is sufficiently close to the label, so that the vacuum chuck 312 is not required to press the label L and suck the label L.

Referring again to fig. 7, in some embodiments, the label bearing mechanism 200 further includes an optical sensor 240 fixed to the label bearing plate 230, where the optical sensor 240 is configured to detect whether the label L is received on the label bearing plate 230. Specifically, the optical sensor 240 is used to detect whether the label carrier 230 carries the label L, so that the situation that the label carrier 230 does not carry the label L, and the labeling mechanism 300 still performs the labeling action to cause that a part of the packaging bags P are not labeled, i.e., the fool-proof effect can be achieved. When the optical sensor detects that the label is not on the label bearing plate 230, the air cylinder 221 drives the label bearing plate 230 to move to the label outlet 110 to receive the label L. After the label carrying plate 230 is received on the label L, the optical sensor 240 detects the label L, the air cylinder 221 drives the label carrying plate 230 to move the label L to the label picking position, and if the label L falls in the process, the optical sensor 240 detects that no label L is on the label carrying plate 230, other alarm devices (such as a warning light and/or an acoustic alarm) can be triggered to remind an operator to process the label.

It will be appreciated that when the optical sensor 240 is a camera (e.g., a CCD camera), the optical sensor 240 may be fixed to one side of the label bearing plate 230 by photographing whether the label is present on the upper surface of the label bearing plate 230. When the vacuum chuck 312 sucks the label L, in order to avoid the optical sensor 240 interfering with the vacuum chuck 312, the optical sensor 240 may be disposed below the label bearing plate 230, and a through hole 232 may be formed in the label bearing plate 230, and the optical sensor 240 may be a laser sensor or an optical fiber sensor, for example, when the optical sensor 240 detects whether the label L is received on the upper surface of the label bearing plate 230 through the through hole 232.

Referring to fig. 9, in some embodiments, the limiting mechanism 400 includes a second fixing frame 410, a limiting cylinder 420 and a limiting plate 430, wherein the limiting cylinder 420 is fixed on the second fixing frame 410, and a piston of the limiting cylinder 420 is retractable along a horizontal direction and is fixedly connected with the limiting plate 430 to drive the limiting plate 430 to move. Wherein, the piston of the limit cylinder 420 extends out to drive the limit plate 430 to abut against one surface of the packaging bag P facing away from the label picking assembly 310, so as to prevent the packaging bag P from moving in a direction away from the label picking assembly 310; the piston of the limiting cylinder 420 is retracted, and the limiting plate 430 is driven to reset.

Specifically, when the vacuum chuck 312 is driven by the horizontal cylinder 326a to perform labeling, the limiting plate 430 is driven by the limiting cylinder 420 and abuts against one surface of the packaging bag P facing away from the vacuum chuck 312, at this time, the packaging bag P is located between the vacuum chuck 312 and the limiting plate 430, and the packaging bag P is blocked by the limiting plate 430 and cannot move in a direction away from the vacuum chuck 312, so that the label L is attached to the packaging bag P.
