Description

Technical Field

[0001] The invention relates to the field of turnover technology, in particular to a box body turnover device for dairy product packaging. Background Art

[0002] In the dairy packaging industry, quality inspection is a key link to ensure product safety, meet consumer expectations and maintain brand image. Among them, the inspection of seal tightness is particularly important because it is directly related to the shelf life, anti-contamination ability and overall quality of the product. However, traditional seal tightness inspection methods mainly rely on manual operations, which have obvious limitations in many aspects.

[0003] First, manual testing has hidden dangers in terms of hygiene. Since the inspectors need to directly contact the packaging boxes, this increases the risk of cross-contamination, especially if hygiene regulations are not strictly followed. This may not only affect the safety of the product, but also pose a threat to the health of consumers.

[0004] Secondly, manual testing is not efficient. On the one hand, the speed of manual operation is limited by human reaction speed and endurance, which cannot be compared with automated equipment. On the other hand, manual testing may be affected by subjective factors such as fatigue and emotions, resulting in unstable and inaccurate test results.

[0005] In the process of checking the tightness of the seal, the flipping operation is an important step. By flipping, the tightness of the seal can be checked more comprehensively and accurately. However, manual flipping often cannot ensure the smoothness and speed of the action, which may cause unnecessary impact on the packaging box, thus affecting the product quality. For this reason, we propose a box flipping device for dairy packaging. Summary of the invention

[0006] The object of the present invention is to provide a box turning device for dairy product packaging to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a box flipping device for dairy product packaging, comprising a conveyor platform, on which a quality inspection area is installed; the quality inspection area comprises a collection module and a flipping mechanism, and when the flipping mechanism flips the packaging box, the collection module is used to perform quality inspection on the packaging box; the flipping mechanism comprises three groups of fixing components with the same structure, and four flippings of the packaging box are achieved through the cooperation between the three groups of fixing components; the fixing component comprises a fixing piece for fixing the top or bottom of the packaging box, a retraction rope is connected to the upper part of the fixing piece, and a retraction assembly for retracting and releasing the retraction rope is connected to the end of the retraction rope away from the fixing piece, and during the entire flipping process, there is always a contact surface between the packaging box and the conveyor platform.

[0008] Further optimized, the fixing part includes two groups of clamping plates whose top ends are respectively connected to the retractable ropes, and an electromagnet is installed inside the clamping plate. Through the action of the electromagnet, suction is generated between the two groups, thereby fixing the packaging box.

[0009] Preferably, the electromagnet is rotatably connected to the clamping plate via a bearing.

[0010] Preferably, an air pump is installed inside, and the air pump generates suction to adsorb the two sets of clamping plates onto the packaging box.

[0011] Preferably, the retractable assembly comprises a first motor, an output end of the first motor is connected to a winding wheel, and the winding wheel is respectively fixedly connected to one end of the two groups of retractable ropes away from the fixing member.

[0012] Further optimization is that a mounting frame is installed on the conveying platform, a second motor is installed on the mounting frame, a rotating shaft is fixed to the output end of the second motor, a rotating wheel is fixed on the rotating shaft, and a plurality of fixing components are installed on the rotating wheel.

[0013] Further optimization is performed, and four groups of fixing components are installed on the rotating wheel.

[0014] Further optimization, the radius of the rotating wheel is half of the height of the packaging box.

[0015] Further optimization is that a guide tube is installed on the retractable rope near the winding wheel area, and the retractable rope is located in the guide tube.

[0016] Further optimized, the acquisition module acquires data through a camera assembly.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention utilizes the principle of the retractable rope and realizes the smooth flipping of the packaging box through the carefully designed fixing components and the retracting and releasing components. During the entire flipping process, the packaging box is always in a protected state, avoiding collision with the conveyor belt or other components, thereby ensuring the integrity of the packaging box and preventing unnecessary damage;

[0019] 2. The present invention uses different gripping positions each time the box is flipped, so that different parts of the box can be fully exposed, thus ensuring the comprehensiveness of the inspection. This design ensures that every corner of the sealing area is carefully inspected, greatly improving the accuracy and reliability of quality inspection;

[0020] 3. The present invention uses automated control, and the flipping device can quickly and accurately complete the flipping action and seamlessly connect with the conveyor table, thus realizing an efficient and continuous quality inspection process. This not only improves production efficiency, but also reduces the impact of human factors on quality inspection results;

[0021] 4. The design of the flipping device of the present invention has certain flexibility and adaptability, and can be adjusted according to packaging boxes of different sizes and shapes. In addition, by adjusting the retracting speed of the shrink rope and the rotation speed of the rotating wheel, the flipping action can be precisely controlled to meet different quality inspection requirements.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-6 , the present invention provides a technical solution:

[0031] Embodiment 1: This embodiment provides a box flipping device for dairy product packaging, including a conveyor 1 and a quality inspection area 2. The quality inspection area 2 is composed of a collection module 3 and a flipping mechanism 4. The flipping mechanism 4 includes three sets of fixed components 5 with the same structure. Through their mutual cooperation, the packaging box can be flipped four times. The fixed component 5 is composed of a fixing part 6, a retracting rope 7 and a retracting component 8. The fixing part 6 is designed as two sets of clamping plates 9, and an electromagnet 10 is installed inside. The two sets of clamping plates 9 generate suction through electromagnetic force, so as to firmly clamp the packaging box. The retracting component 8 is composed of a first motor 11 and a winding wheel 12, which is used to control the retraction and release of the retracting rope 7 to achieve the flipping action. During the flipping process, the packaging box always keeps in contact with the conveyor 1, ensuring the stability of the flipping.

[0032] The specific flipping process can be broken down into four flippings;

[0033] During the first flip, after the package box passes through the conveyor 1 and enters the quality inspection area 2, multiple groups of infrared sensors are installed inside the quality inspection area 2. When the package box is conveyed to the bottom of the first group of fixing components 5, the infrared sensors are used for detection, and the system controls the electromagnet 10 to work. The two groups of electromagnets 10 are energized instantly to generate magnetic force, and the two groups of clamping plates 9 generate mutually attractive magnetic forces to clamp the top of the package box. However, since the bottom of the package box is still on the conveyor 1, the bottom of the package box continues to move with the conveyor 1 under the action of the conveyor 1, and at the same time as the infrared sensor is started, the first motor 11 starts to work, and the first motor 11 drives the winding wheel 12 to rotate. At this time, the state of the retractable rope 7 is the rope releasing state;

[0034] The second flip, the first flip ends with the packaging box changing from standing to lying. At this time, when the sensor located on the second group of fixed components 5 detects the packaging box, the retraction rope 7 on the first group of fixed components 5 begins to retract the retraction rope 7, and the electromagnet 10 on the first group of fixed components 5 loses its magnetic force. The second flip is the same as the first, the difference is that the clamping part changes from the top to the bottom, and the second flip, the retraction rope 7 is first reeled in and then released after resetting.

[0035] The third flipping is completed between the second set of fixing components 5 and the third set of fixing components 5. The third flipping also uses the second fixing components 5. After the second flipping is completed, the retractable rope 7 is in a retracted state. This process can be completed using a timer. After the second flipping is completed, the retractable rope 7 starts to release the rope and the third flipping is performed.

[0036] The principle of the fourth flip is the same as the above principle.

[0037] During the turning process, the camera acquisition module 3 determines whether the packaging box is damaged or leaking by acquiring images.

[0038] Embodiment 2: Based on Embodiment 1, this embodiment further improves the design of the fixing member 6. The electromagnet 10 is rotatably connected to the clamping plate 9 through a bearing. The main purpose of connecting the electromagnet 10 and the clamping plate 9 through a bearing is that when the two groups of electromagnets 10 are adsorbed in the air, the conveyor belt drives one end of the packaging box to move, so that the packaging box is flipped. During this flipping process, the retractable rope 7 and the packaging box are not in a straight line. In order to avoid the angle between the retractable rope 7 and the packaging box causing the adsorption force to decrease, the electromagnet 10 is set to be rotatable relative to the retractable rope 7, so that the adsorption surface of the electromagnet 10 can always be in close contact with the packaging box, effectively preventing the misalignment between the electromagnet 10 and the packaging box.

[0039] In addition, an air pump is additionally provided inside the clamping plate 9. The suction force generated by the air pump further enhances the adsorption capacity of the clamping plate 9 on the packaging box, thereby ensuring that the packaging box will not fall off during the flipping process.

[0040] Here, the existing adsorption-type clamping piece can be used, and the air pressure generated by the air pump is used to adsorb the packaging box.

[0041] Embodiment 3: Based on Embodiment 1 or 2, this embodiment optimizes the retractable assembly 8. A guide tube 17 is installed on the retractable rope 7 near the winding wheel 12 to ensure that the retractable rope 7 can always maintain a straight line during the retractable process, thereby avoiding the instability of the retractable rope 7 due to bending or twisting. At the same time, the guide tube 17 can also protect the retractable rope 7 and extend its service life.

[0042] Embodiment 4: This embodiment integrates and optimizes the entire flipping device. A mounting frame 13 is installed on the conveying platform 1, and a second motor 14, a rotating shaft 15 and a rotating wheel 16 are installed on the mounting frame 13. Multiple groups, such as four groups of fixed components 5 are installed on the rotating wheel 16. Through the drive of the second motor 14, the synchronous flipping of multiple groups of fixed components 5 can be achieved, thereby improving the quality inspection efficiency.

[0043] In order to improve the whole turning efficiency and apply the equipment to the production line, a plurality of fixed components 5 are set in one turning link, so that continuous production can be realized;

[0044] Specific principles:

[0045] In the first flipping, during the process of clamping the packaging box, the wire release speed is higher than the wire release speed in Example 1, and the first flipping ends when the rotating wheel 16 rotates 90 degrees;

[0046] When performing the second flip, the rotating wheel rotates 90 degrees. When performing the third flip, that is, the process from 4 to 5 in the figure, the rotating wheel does not rotate, and the retracting rope 7 continues to release the rope;

[0047] In order to meet the pause process from the second to the third flipping, the spacing between the packaging boxes is set to the height of two packaging boxes.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
