Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging technology, specifically to a bottle orientation mechanism, a labeling device, and a labeling method. Background Technology

[0002] Currently, oral liquid bottles are usually straightened after labeling. However, for oral liquid bottles with irregular bottle heads, straightening them after labeling will result in inconsistent label positions. In addition, after labeling, the oral liquid bottles need to be transported and unloaded before being boxed. However, the oral liquid bottles may be deflected during labeling, resulting in misaligned positions. It is impossible to ensure that all the bottles are in the same position when boxing, which is not conducive to the consistency and aesthetics of subsequent boxing. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a bottle orientation mechanism that can straighten the bottle, orient the bottle, and facilitate subsequent labeling and boxing.

[0004] The present invention further provides a labeling device and method for straightening and orienting the bottle before labeling and boxing, so as to ensure the consistency and aesthetics of labeling and boxing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A bottle orientation mechanism includes a rotating roller, a detection mechanism for detecting whether the bottle is in the correct orientation, a rotation drive mechanism for driving the rotating roller to rotate, and a lifting drive mechanism for driving the rotating roller to move up and down.

[0007] As a further improvement to the above technical solution:

[0008] The rotating rollers are provided in multiple ways and are arranged at intervals along the bottle conveying direction. The rotating drive mechanism includes a mounting base and multiple rotating motors corresponding to the rotating rollers. One of two adjacent rotating rollers is connected to a rotating motor, and the other is connected to a rotating motor through a transmission assembly. The two adjacent rotating motors are arranged staggered on the mounting base.

[0009] The transmission assembly is a synchronous belt assembly, in which the driving pulley is connected to a rotary motor and the driven pulley is connected to a rotary roller.

[0010] The detection mechanism includes multiple photoelectric switches, which are arranged below the rotating roller.

[0011] The lifting drive mechanism includes a support base and a lifting module mounted on the support base. The mounting base is connected to the lifting module. Lifting guide rails are provided on both sides of the support base, and the mounting base slides on the lifting guide rails.

[0012] The rotating roller includes a roller shaft and a roller wheel. One end of the roller shaft is connected to a rotation drive mechanism, and the other end is detachably connected to the roller wheel.

[0013] The roller has a flexible pad on its outer periphery.

[0014] A labeling device includes a first conveying mechanism, on which a mold for carrying bottles during conveying is provided. The conveying direction of the first conveying mechanism is provided with a feeding mechanism, a labeling mechanism and a discharging mechanism in sequence. The bottle orientation mechanism described above is provided between the labeling mechanism and the feeding mechanism and between the labeling mechanism and the discharging mechanism.

[0015] The labeling device also includes a second conveying mechanism arranged parallel to the first conveying mechanism. The second conveying mechanism is also equipped with a feeding mechanism, a labeling mechanism, and a discharging mechanism in sequence in the conveying direction of the second conveying mechanism. Bottle orientation mechanisms are provided between the labeling mechanism and the feeding mechanism and between the labeling mechanism and the discharging mechanism. The feeding direction of the second conveying mechanism is the same as that of the first conveying mechanism.

[0016] A labeling method includes the following steps:

[0017] S1. Feeding: The bottle body is fed from the feeding mechanism into the mold;

[0018] S2. First straightening before labeling: The conveying mechanism transports the bottle to the first bottle orientation mechanism. The lifting drive mechanism of the bottle orientation mechanism drives the rotating roller to descend until it contacts the bottle. The rotation drive mechanism drives the rotating roller to rotate, causing the bottle to rotate. After the detection mechanism detects that the bottle is straightened in place, the rotating roller stops rotating.

[0019] S3, Labeling: The uprighted bottle is then conveyed to the labeling mechanism for labeling;

[0020] S4. Second straightening before boxing: After the bottle label is applied, the bottle is conveyed to the second bottle orientation mechanism to straighten the bottle again.

[0021] S5. Unloading: The uprighted bottle body continues to be conveyed to the unloading mechanism for unloading.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] The bottle orientation mechanism disclosed in this invention has a rotating roller initially positioned above the bottle. When the bottle needs to be aligned and oriented, a lifting drive mechanism drives the rotating roller to descend and contact the bottle. Then, a rotation drive mechanism drives the rotating roller to rotate, causing the bottle to rotate back to its upright position. When the detection mechanism detects that the bottle has been aligned, the rotating roller stops rotating, thus achieving the alignment and orientation of the bottle and ensuring the consistency and aesthetics of subsequent labeling and boxing.

[0024] The labeling device disclosed in this invention has the aforementioned bottle orientation mechanism between the labeling mechanism and the feeding mechanism, and between the labeling mechanism and the unloading mechanism. A first alignment and orientation is performed before labeling to ensure consistent labeling positions. However, the bottle may deflect during the labeling process, so a second alignment and orientation is performed before unloading to ensure consistent bottle positions during unloading, which facilitates the consistency and aesthetics of subsequent boxing.

[0025] The labeling method of the present invention performs a first straightening and orientation before labeling to ensure consistent labeling positions. However, the bottle may deflect during the labeling process, so a second straightening and orientation is performed before feeding to ensure consistent bottle positions during feeding, which facilitates the consistency and aesthetics of subsequent boxing.

[0035] Example 1

[0036] Figures 2 to 4 An embodiment of the present invention is shown. The bottle orientation mechanism of this embodiment includes a rotating roller 7, a detection mechanism 8 for detecting whether the bottle 12 is aligned in place, a rotation drive mechanism 9 for driving the rotating roller 7 to rotate, and a lifting drive mechanism 10 for driving the rotating roller 7 to rise and fall.

[0037] In this bottle orientation mechanism, the rotating roller 7 is initially positioned above the bottle 12. When the bottle 12 needs to be aligned and oriented, the lifting drive mechanism 10 drives the rotating roller 7 to descend and contact the bottle 12. Then, the rotation drive mechanism 9 drives the rotating roller 7 to rotate, causing the bottle 12 to rotate back to the correct position. When the detection mechanism 8 detects that the bottle 12 is aligned correctly, the rotating roller 7 stops rotating, thus achieving the alignment and orientation of the bottle 12 and ensuring consistency and aesthetics during subsequent labeling and boxing. Specifically, the detection mechanism 8 typically detects irregular bottle heads, such as heart-shaped bottle heads, on the top of the bottle 12. If the bottle 12 is not aligned correctly, the detection mechanism 8 cannot detect the irregular bottle head, requiring the bottle orientation mechanism to orient and align it. Once aligned correctly, the detection mechanism 8's detection of the irregular bottle head indicates that the alignment is complete.

[0038] In this embodiment, multiple rotating rollers 7 are provided, and the multiple rotating rollers 7 are arranged at intervals along the conveying direction of the bottle body 12. The rotating drive mechanism 9 includes a mounting base 91 and multiple rotating motors 92 corresponding to the rotating rollers 7. One of two adjacent rotating rollers 7 is connected to the rotating motor 92, and the other is connected to the rotating motor 92 through a transmission assembly 93. The two adjacent rotating motors 92 are staggered on the mounting base 91. Taking 18 rotating rollers 7 as an example, 9 rotating rollers 7 (odd number) are directly connected to the rotating motors 92, and the other 9 (even number) rotating rollers 7 are connected to the rotating motors 92 through the transmission assembly 93. Thus, the rotating motors 92 can be staggered and do not need to be in a row, making the structure more compact.

[0039] In this embodiment, the transmission assembly 93 is a synchronous belt assembly. The driving pulley of the synchronous belt assembly is connected to the rotary motor 92, and the driven pulley is connected to the rotary roller 7. This provides good synchronization, allowing each rotary roller 7 to simultaneously straighten and orient multiple bottles 12, thus improving orienting efficiency.

[0040] In this embodiment, the detection mechanism 8 includes multiple photoelectric switches 81, which are arranged below the rotating roller 7. Preferably, the photoelectric switches 81 are connected to corresponding rotary motors 92, and the rotary motors 92 stop driving when the photoelectric switches 81 detect irregular bottle heads.

[0041] In this embodiment, the lifting drive mechanism 10 includes a support base 101 and a lifting module 102 disposed on the support base 101. A mounting base 91 is connected to the lifting module 102. Lifting guide rails 103 are provided on both sides of the support base 101, and the mounting base 91 slides on the lifting guide rails 103. The lifting module 102 drives the mounting base 91 to rise and fall, thereby driving the rotating roller 7 to rise and fall. At the same time, the lifting guide rails 103 provide guidance for the rise and fall of the rotating roller 7.

[0042] In this embodiment, the rotating roller 7 includes a roller shaft 71 and a roller wheel 72. One end of the roller shaft 71 is connected to the rotating drive mechanism 9, and the other end is detachably connected to the roller wheel 72. This facilitates the disassembly, assembly, and replacement of the roller wheel 72.

[0043] In this embodiment, a flexible pad 73 is provided on the outer periphery of the roller 72. When the roller 72 contacts the bottle 12, the flexible pad 73 can protect the bottle 12. Preferably, the flexible pad 73 is a blue polyurethane rubber pad with a Shore hardness of 50-60 degrees, and it does not crack, become brittle, or degrade and deform at a temperature of 135 degrees Celsius, and it does not release harmful gases.

[0044] Example 2

[0045] Figure 1An embodiment of the labeling device of the present invention is shown. The labeling device of this embodiment includes a first conveying mechanism 1. The first conveying mechanism 1 is provided with a mold 11 for carrying the bottle body 12 during conveying. The conveying direction of the first conveying mechanism 1 is provided with a feeding mechanism 2, a labeling mechanism 4 and a discharging mechanism 6 in sequence. The above-mentioned bottle orientation mechanism is provided between the labeling mechanism 4 and the feeding mechanism 2 and between the labeling mechanism 4 and the discharging mechanism 6.

[0046] The labeling device is equipped with the aforementioned bottle orientation mechanism between the labeling mechanism 4 and the feeding mechanism 2, and between the labeling mechanism 4 and the unloading mechanism 6. The first orientation is performed before labeling to ensure that the labeling position is consistent. However, the bottle 12 may deflect during the labeling process. Therefore, the second orientation is performed before unloading to ensure that the bottle 12 is in a consistent position during unloading, which facilitates the consistency and aesthetics of subsequent boxing.

[0047] In this embodiment, the labeling device further includes a second conveying mechanism 3 arranged parallel to the first conveying mechanism 1. The second conveying mechanism 3 is also equipped with a support for the bottle body 12 during conveying. The conveying direction of the second conveying mechanism 3 is also sequentially provided with a feeding mechanism 2, a labeling mechanism 4, and a discharging mechanism 6. Bottle orientation mechanisms are provided between the labeling mechanism 4 and the feeding mechanism 2, and between the labeling mechanism 4 and the discharging mechanism 6. The feeding direction of the second conveying mechanism 3 is the same as that of the first conveying mechanism 1. The inclusion of the second conveying mechanism 3 can improve production efficiency, and the fact that the feeding directions of the first conveying mechanism 1 and the second conveying mechanism 3 are the same results in a compact structure and a small footprint.

[0048] Example 3

[0049] The labeling method of this embodiment includes the following steps:

[0050] S1. Feeding: Bottle 12 is fed from feeding mechanism 2 into mold 11;

[0051] S2. First alignment and orientation before labeling: The conveying mechanism conveys the bottle 12 to the first bottle orientation mechanism. The lifting drive mechanism 10 of the bottle orientation mechanism drives the rotating roller 7 to descend to contact the bottle 12. The rotation drive mechanism 9 drives the rotating roller 7 to rotate, causing the bottle 12 to rotate. After the detection mechanism 8 detects that the bottle 12 is aligned in place, the rotating roller 7 stops rotating.

[0052] S3, Labeling: The uprighted bottle 12 continues to be conveyed to the labeling mechanism 4 for labeling;

[0053] S4. Second straightening and orientation before boxing: After the bottle 12 is labeled, it continues to be conveyed to the second bottle orientation mechanism to straighten the bottle again;

[0054] S5. Unloading: The uprighted bottle body 12 continues to be conveyed to the unloading mechanism 6 for unloading.

[0055] This labeling method involves a first alignment and orientation before labeling to ensure consistent labeling positions. However, the bottle 12 may deviate during the labeling process. Therefore, a second alignment and orientation is performed before feeding to ensure consistent bottle 12 positions during feeding, which facilitates consistency and aesthetics in subsequent boxing.

[0056] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
