Description

Technical Field

[0001] This invention relates to the field of labeling machines, and more particularly to a flip labeling production line and its working method. Background Technology

[0002] Labeling machines, as one of the most technologically advanced pieces of equipment in the downstream packaging process, have gained widespread recognition from customers for their excellent high-speed stability, unique and ingenious design, and safe human-machine collaborative operation. Application areas include: food, beverage and pharmaceutical industries, condiments, juices, injection needles, milk, refined oils, etc.

[0003] Patent No. 202222328274.6 discloses a labeling device for a labeling machine, which employs a reciprocating up-and-down labeling motion. In the prior art, most current labeling machines use this motion for labeling. For bottles or boxes with different sizes at both ends, existing labeling machines can only handle the bottle or box entering the machine with the smaller end facing up, before the machine can apply the label; for example... Figure 1 The image shows a common yogurt packaging box, typically truncated cone-shaped, with the larger diameter end extending outwards to form a continuous cup. Usually, eight boxes of yogurt make up an eight-cup continuous container. For this type of continuous cup product, current technology mostly uses labeling, where the label is applied inside the mold during cup forming. However, this method involves very complex labeling equipment. Labeling machines are less common for continuous cup products. Another existing method involves the label falling from the machine and being lifted by a transfer mechanism to apply the label from bottom to top. This type of labeling machine has a complex bottom structure, making installation and maintenance extremely inconvenient.

Implementation

[0018] This invention discloses a flip label production line and its working method. The first flipping mechanism, which consists of a first conveying module, a flipping disc module, and a second conveying module, can adjust the opening direction of the packaging container. It is particularly suitable for packaging containers that have just been filled and sealed, and can realize automated labeling, thereby solving the problems existing in the prior art.

[0019] The technical solutions of the embodiments of the present invention will be clearly and thoroughly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Please refer to... Figures 1 to 6 The present invention is a flip label production line for use in a packaging container 01 with a supporting edge 001 on the outside. It includes an input mechanism 1, a labeling mechanism 2, a heat shrinking mechanism 3, and an output mechanism 4, and also includes a first flipping mechanism 5. The first flipping mechanism 5 is disposed between the input mechanism 1 and the labeling mechanism 2, and is used to flip the opening direction of the packaging container 01 from upward to downward, including a first conveying module a1, a flipping plate module a2 and a second conveying module a3 arranged sequentially on the support 002; The flipping tray module a2 includes at least one flipping tray a21 and a power component a22. The flipping tray a21 is provided with a limiting groove a211 that cooperates with the support edge 001. The first conveying module a1 is used to convey the packaging container 01 to the flipping tray a21 until the support edge 001 reaches the set position of the limiting groove a211. The power component a22 is used to drive the flipping tray a21 to rotate and cause the packaging container 01 to flip and fall onto the second conveying module a3. The second conveying module a3 conveys the packaging container 01 to the next work station.

[0020] First, it should be noted that the opening direction mentioned in this invention refers to the opening direction of the packaging container 01 itself. The opening direction of the packaging container 01 entering the input mechanism 1 is always upward, because the packaging container 01 is either an empty container or a container that has just been filled and sealed. If it is an empty container, then the opening of the labeled packaging container 01 is kept facing upward so that the next process can be filled. If it is a container that has just been filled and sealed, then the state of the packaging container 01 itself is that the opening is facing upward. Next, in this embodiment of the invention, since the packaging container 01 has a supporting edge 001, it can only be flipped and labeled. The input mechanism 1 transports the packaging container 01 to the first flipping mechanism 5. The first conveying module a1 in the first flipping mechanism 5 transports the packaging container 01 to the flipping plate a21, that is, the supporting edge 001 reaches the set position of the limiting groove a211. The flipping plate a21 will support and position the packaging container 01 through the supporting edge 001. Then, the power component a22 reverses the opening direction of the packaging container 01 by rotating the flipping plate a21. Then, the second conveying module a3 transports the packaging container 01 with the reversed opening direction to the labeling mechanism 2. Then, the labeling mechanism 2 and the heat shrinking mechanism 3 sequentially put the packaging film 003 on the packaging container 01 and heat shrink it. Finally, it can be directly transported to the next process by the output mechanism 4, or a mechanism similar to the first flipping mechanism 5 can be set between the heat shrinking mechanism 3 and the output mechanism 4 to restore the opening direction of the packaging container 01. This is not limited here.

[0021] It must be emphasized that, under certain circumstances, the input mechanism 1 can be combined with the first conveying module a1 in the first flipping mechanism 5. Similarly, if the heat shrinking mechanism 3 and the output mechanism 4 have a mechanism similar to the first flipping mechanism 5, then the output module of the output mechanism 4 can be combined with the output mechanism 4. In this case, the working efficiency of the input mechanism 1 and the output mechanism 4 will be sacrificed, because after being combined, the input mechanism 1 and the first conveying module a1 in the first flipping mechanism 5 will have the same speed. Therefore, the solution designed for this special case also falls within the scope of protection of this invention.

[0022] Preferred, The flip disk module a2 includes at least n+1 flip disks a21 arranged opposite to each other; In the n-row connected cup packaging containers, the support edges 001 on both sides and the support edges 001 between two adjacent rows of packaging containers cooperate with the limiting grooves a211 opened on the flip plate.

[0023] In one embodiment of the present invention, the flip disk module a2 includes three flip disks a21 arranged opposite to each other; In the double-row cup packaging container, the supporting edges 001 located on both sides and in the middle cooperate with the limiting grooves a211 opened on the flip plate a21.

[0024] It should be noted that, in order to stably support the n rows of interconnected cup containers, the optimal solution is to use n+1 opposing rotating discs a21. The n-1 rotating discs a21 support the supporting edges 001 of adjacent rows of containers, while the two outermost rotating discs 21 support the two outermost supporting edges 001. Therefore, for the more common double-row interconnected cup containers, three opposing rotating discs a21 can be used to stably support and position the containers. Of course, using only two opposing rotating discs a21 to support the outer supporting edges 001 of the double-row interconnected cup containers is also possible, but this may result in the middle of the double-row interconnected cup containers collapsing.

[0025] Preferred, The flip disk a21 is provided with at least one limiting groove a211; The width of the limiting groove a211 increases in the direction of the opening.

[0026] Preferred, The flip disk a21 is provided with four limiting grooves a211 arranged in a cross shape.

[0027] It should be noted that, depending on production requirements and the height of the packaging container 01, at least one limiting groove a211 can be provided on the flip plate a21. Generally speaking, it is better to provide four limiting grooves a211 in a cross shape on the flip plate a21. When the height of the packaging container 01 is low, the number of limiting grooves a211 on the flip plate a21 can be increased, for example, up to 6 limiting grooves a211. This is not limited here.

[0028] Preferred, The flip-up module a2 also includes a sensor a4 mounted on the bracket; The sensor a4 is used to monitor the position of the packaging container 01 and / or the flip tray a21.

[0029] It should be noted that the sensor a4 is configured to accurately identify the position of the packaging container and the limiting groove a211, thus enabling the supporting edge 001 of the packaging container to accurately enter the set position of the limiting groove a211.

[0030] Preferred, Includes n sequentially arranged labeling mechanisms 2; Each of the labeling mechanisms 2 performs a labeling process on a specific row of n rows of connected cup packaging containers.

[0031] Preferred, It also includes a second flipping mechanism 6; The height of the conveying surface of the first conveying module in the first flipping mechanism 5 is lower than the height of the conveying surface of the second conveying module; The height of the conveying surface of the first conveying module of the second flipping mechanism 6 is higher than the height of the conveying surface of the second conveying module; The second flipping mechanism 6 is disposed between the heat shrinking mechanism and the output mechanism, and is used to restore the opening direction of the packaging container.

[0032] First, it should be noted that the second flipping mechanism 6 has a similar structure and function to the first flipping mechanism 5. They can be completely identical or symmetrically designed; no limitation is made here. It is important to emphasize that the height of the conveying surface of the first conveying module and the conveying surface of the second conveying module may be on the same horizontal plane or have a height difference. The specific situation depends on the position of the support edge 001 on the packaging container, with the open end as the top. For example, assuming the support edge 001 is located on the top outer side of the packaging container, then the following conditions must be met: the height of the conveying surface of the first conveying module in the first flipping mechanism 5 is lower than the height of the conveying surface of the second conveying module; the height of the conveying surface of the first conveying module in the second flipping mechanism 6 is higher than the height of the conveying surface of the second conveying module.

[0033] The present invention provides a flip-label production line for use in a packaging container 01 with a supporting edge 001 on the outside. It includes an input mechanism 1, a labeling mechanism 2, a heat-shrinking mechanism 3, and an output mechanism 4, and also includes a first flipping mechanism 5. The first flipping mechanism 5 is disposed between the input mechanism 1 and the labeling mechanism 2, and is used to flip the opening direction of the packaging container 01 from upward to downward. It includes a first conveying module a1, a flipping disc module a2, and a second conveying module a3 sequentially arranged on a support 002. The flipping disc module a2 includes at least one flipping disc a21 and a power component a22. The flipping disc a21 is provided with a limiting groove a211 that cooperates with the supporting edge 001. The first conveying module a1 is used to convey the packaging container 01 to the flipping disc a21 until the supporting edge 001 reaches a set position of the limiting groove a211. The power component a22 is used to drive the flipping disc a21 to rotate and cause the packaging container 01 to flip and fall onto the second conveying module a3. The second conveying module a3 conveys the packaging container 01 to the next work station. The first flipping mechanism 5 and the second flipping mechanism 6, which are composed of the first conveying module a1, the flipping disc module a2 and the second conveying module a3, enable the flipping label production line of the present invention to adjust the opening direction of the packaging container. It is particularly suitable for packaging containers that have just been filled and sealed, and can realize automated labeling, thereby solving the problems existing in the prior art.

[0034] The flip-label production line of the present invention has been described above, with a focus on the structure and operation of the first flipping mechanism 5 and the second flipping mechanism 6. An embodiment of the working method of the flip-label production line of the present invention is described below. Please refer to [link / reference]. Figure 5 and Figure 6 The working method of the flip-label production line of the present invention includes: S1: Receives an upward-opening cup-packing container via the input mechanism; The reason why the opening of the continuous cup packaging container faces upward has already been explained in the previous embodiment, and will not be repeated here. As a preferred embodiment, the flip-label production line of the present invention can be set after the filling and sealing station, so the continuous cup packaging containers entering the input mechanism have already been filled and sealed.

[0035] S2: The cup packaging container is flipped over by the first flipping mechanism, that is, flipped from opening upward to opening downward; S3: Each packaging container on the continuous cup packaging container is labeled sequentially by the labeling mechanism; S4: The packaging film is heat-shrinked using a heat-shrinking mechanism; S5: The cup packaging container is flipped over by the second flipping mechanism, that is, the opening is restored to its initial state; S6: The processed cup packaging container is then sent to the next process.

[0036] Preferred, Step S3 includes: The continuous cup packaging container is an n-row continuous cup packaging container; The n labeling mechanisms sequentially label each row of connected cup packaging containers.

[0037] It should be noted that, since the space between each row in the n-row cup packaging container is relatively small, it is difficult to label each row at the same time. Therefore, the present invention adopts multiple labeling mechanisms to perform labeling operations on each row in turn, which can ensure the labeling effect.

[0038] The first flipping mechanism, consisting of a first conveying module, a flipping disc module, and a second conveying module, enables the working method of the flipping label production line of the present invention to adjust the opening direction of the packaging container. It is particularly suitable for packaging containers that have just been filled, and can achieve automated labeling, thereby solving the problems existing in the prior art.

[0039] The above provides a detailed description of the flip-label production line provided by the present invention. For those skilled in the art, based on the ideas of the embodiments of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
