Description

Technical Field

[0001] The utility model relates to the field of diaper packaging machines, specifically a single-channel packaging machine for baby diapers. Background Technique

[0002] Diapers are commonly used daily necessities for babies, which is a general term for diaper pads, diapers, and pull-up pants. A dry diaper can keep a baby sleeping soundly throughout the night. Due to its strong water absorption, it is commonly known as a "diaper". When diapers are sold on the market, they are usually packaged by a single-channel packaging machine to facilitate customers to purchase in large quantities.

[0003] The single-channel packaging machine for diapers is an intermediate device connecting the front-end diaper production line and the back-end boxing and sealing machine. It sorts the single-piece diaper products output from the front-end production line into product rows according to the number of pieces required by customers, packs them into bags, and seals them.

[0004] However, the existing single-channel packaging machine for diapers usually has a packaging speed of 450 pieces per minute. Although it is a leading product in terms of speed among single-channel packaging machines for diapers on the market, it cannot match the front-end diaper production line with a higher feeding speed. High-speed feeding will cause interference between the edges of diaper products and the belt system of the feeding unit, causing the diaper products to deviate from their original movement trajectories. Under the influence of these two factors, the feeding process of some diaper products fails, and the diapers will become blocked at the connection between the feeding unit and the sheet sorting unit, resulting in a shutdown phenomenon. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a single-channel packaging machine for baby diapers to solve the technical problems that the existing diaper packaging machine is difficult to cope with a higher packaging rate and is likely to cause the deviation of the transportation position of diapers.

[0006] To achieve the above object, the present utility model provides the following technical solution: A single-channel packaging machine for baby diapers, including a packaging machine main body and baby diapers. A feeding unit is arranged at the front section of the packaging machine main body. The feeding unit includes a belt system and a product detection sensor. A blowing unit is arranged on one side of the belt system. The blowing unit includes an air pump, an air pipe, and a blowing nozzle. A sheet sorting unit is arranged above the packaging machine main body.

[0007] By adopting the above technical solution, by connecting an external air pump, high-pressure air flow is accurately blown onto the surface of the diaper through the air pipe and the air nozzle, and an appropriate wind pressure is applied, effectively solving the problem that the diaper may deviate from the track due to interference between the edge and the belt system during the high-speed feeding process, and ensuring that the diaper can reach the sheet sorting unit stably and accurately.

[0008] Further, there are two groups of the belt systems, and they are arranged in a relative structure. The two groups of belt systems are arranged vertically.

[0009] By adopting the above technical solution, when multiple baby diapers enter the feeding unit, these two groups of belt systems can simultaneously grip both sides of the diaper, effectively preventing the diaper from shifting or swaying during transportation due to the deficiencies of a single belt system. This gripping method not only ensures that the diaper can move forward smoothly along the predetermined path but also improves the reliability of transportation.

[0010] Furthermore, the two groups of belt systems are used to flip the baby diaper, and the distance between the two groups of belt systems is adapted to the thickness of the baby diaper.

[0011] By adopting the above technical solution, through the collaborative work of the two groups of belt systems, this flipping process can be completed smoothly and quickly, ensuring that the diaper can accurately enter the sheet arranging unit for subsequent sorting and packaging.

[0012] Furthermore, the sheet arranging unit includes a belt and a servo motor. A plurality of limiting plates are equidistantly arranged on the outer side of the belt, and a limiting groove is formed between adjacent limiting plates for accommodating and restricting a single baby diaper.

[0013] By adopting the above technical solution, when the diaper is flipped from the belt system and conveyed to the sheet arranging unit, these limiting plates can effectively guide the diaper to a predetermined position. Since the distance between the limiting plates is fixed, they can ensure that each diaper is individually and neatly accommodated in the limiting groove formed by adjacent limiting plates.

[0014] Furthermore, an electric push rod is arranged on one side of the sheet arranging unit. A push plate is arranged at the telescopic end of the electric push rod, and the push plate has two but not limited to two length dimensions.

[0015] By adopting the above technical solution, the electric push rod, as a power source, can drive the push plate to move through its telescopic action. The push plate, as a component that directly contacts and pushes the baby diaper, plays a key role in the sheet arranging process.

[0016] Furthermore, the product detection sensor is a photoelectric sensor, and its model is: Omron E3Z-D61, which is used to detect the transportation quantity and speed of the baby diaper.

[0017] By adopting the above technical solution, in the production and packaging process of baby diapers, it is crucial to ensure the accuracy of the transportation quantity and the stability of the speed. The photoelectric sensor can non-contact detect the presence of the diaper by emitting and receiving light, thereby achieving accurate counting of the transportation quantity.

[0018] In summary, the present utility model mainly has the following beneficial effects:

[0019] 1. The utility model adds a blowing unit at the connection between the diaper feeding unit and the sheet arranging unit through a belt system and a blowing unit. When the diaper is feeding at high speed, the blowing unit generates high-pressure air flow through an external air pump, and blows the air flow directly onto the surface of the diaper through an air pipe and an air nozzle. This air pressure effectively stabilizes the movement trajectory of the diaper, preventing it from deviating from the original path due to interference between the edge and the belt system during high-speed transmission. In this way, even under the condition of high-speed feeding, the diaper can reach the sheet arranging unit smoothly and accurately. At the same time, the role of the control center cannot be ignored. It is responsible for receiving and processing data from the product detection sensor, and then quickly sending a movement instruction to the sheet arranging unit according to this information. Due to the assistance of the blowing unit, the sheet arranging unit can respond to these instructions more quickly and accurately, and cooperate closely with the feeding unit. This efficient collaborative work not only improves the feeding speed of the diaper, but also ensures the stability and continuity of the entire packaging process, thus realizing the high-speed feeding function and improving the production efficiency;

[0020] 2. The utility model realizes the effective clamping and transportation of multiple baby diapers by setting two groups of belt systems. As the second solution provided by this application, that is, the second embodiment, by setting two groups of belt systems, it not only ensures the stability of the diaper during transportation, but also gradually changes the diaper originally transported horizontally into a vertically transported state through the collaborative work of the belt systems. At the same time, this transformation perfectly cooperates with the subsequent sheet arranging unit, enabling the diaper to be accurately placed in the corresponding limit slots. This continuous process not only improves the sorting efficiency of the diaper, but also greatly speeds up the entire transportation process. Due to the stable clamping force provided by the belt system, the diaper is not easy to slip or shift during transportation, thus reducing sorting errors or repetitive work caused by incorrect positions.

[0029] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0030] Embodiment 1:

[0031] Single-channel packaging machine for baby diapers, such as Figures 1-4As shown in the figure, it includes a packaging machine main body 1 and baby diapers 8. At the front section of the packaging machine main body 1, there is a feeding unit 9. The feeding unit 9 includes a belt system 6 and a product detection sensor 4. On one side of the belt system 6, there is a blowing unit 7. The blowing unit 7 includes an air pump, an air pipe, and a blowing nozzle. Above the packaging machine main body 1, there is an alignment unit 2. By connecting an external air pump, high-pressure air is accurately blown onto the surface of the diaper through the air pipe and the nozzle, applying an appropriate wind pressure to effectively solve the problem that the diaper may deviate from the track due to interference between the edge and the belt system 6 during the high-speed feeding process, ensuring that the diaper can reach the alignment unit 2 stably and accurately. At the same time, the control center plays a key role in the whole process. It is responsible for receiving and processing the data transmitted by the product detection sensor 4, and quickly sending a motion instruction to the alignment unit 2 according to the real-time situation. Due to the assistance of the blowing unit 7, the alignment unit 2 can respond to these instructions more quickly and accurately, and cooperate closely with the feeding unit 9.

[0032] Embodiment 2:

[0033] Refer to Figure 3 、 Figure 4 There are two groups of belt systems 6, and they are arranged in a relative structure. The two groups of belt systems 6 are arranged vertically. When multiple baby diapers enter the feeding unit 9, these two groups of belt systems 6 can hold both sides of the diaper at the same time, effectively preventing the diaper from shifting or shaking due to the deficiency of a single belt system 6 during transportation. This clamping method not only ensures that the diaper can move forward smoothly along the predetermined path, but also improves the reliability of transportation. At the same time, the two groups of belt systems are arranged vertically. This layout makes the diaper more smooth during the process of changing from horizontal transportation to vertical transportation. As the belt system 6 gradually moves, the diaper is smoothly lifted and vertically enters the subsequent alignment unit 2. This vertical setting not only simplifies the flipping process of the diaper, but also reduces the risk of diaper damage or blockage caused by improper flipping.

[0034] Refer to Figure 3 、 Figure 4 The two groups of belt systems 6 are used to flip the baby diaper 8, and the distance between the two groups of belt systems 6 is adapted to the thickness of the baby diaper 8. Through coordinated work, the two groups of belt systems can complete this flipping process smoothly and quickly, ensuring that the diaper can accurately enter the alignment unit 2 for subsequent sorting and packaging. At the same time, the distance between the two groups of belt systems 6 is adapted to the thickness of the baby diaper 8, ensuring that the belt system 6 can apply appropriate pressure when clamping the diaper, neither too tight to cause diaper damage nor too loose to cause the diaper to slip or shift during transportation.

[0035] Refer to Figure 3, the sheet arranging unit 2 includes a belt 21 and a servo motor. A plurality of limiting plates 22 are equidistantly arranged on the outer side of the belt 21. A limiting groove 23 is formed between adjacent limiting plates 22 for accommodating and restricting a single baby diaper 8. When the diaper is flipped and conveyed from the belt system 6 to the sheet arranging unit 2, these limiting plates 22 can effectively guide the diaper into a predetermined position. Since the distance between the limiting plates 22 is fixed, they can ensure that each diaper is individually and neatly accommodated in the limiting groove 23 formed by adjacent limiting plates 22. At the same time, the existence of the limiting groove 23 restricts the movement of the diaper during transportation, preventing the overlap or interlacing of diapers, thus ensuring that each diaper can enter the subsequent packaging process in the correct posture.

[0036] Refer to Figure 3 , an electric push rod 3 is arranged on one side of the sheet arranging unit 2. A push plate 5 is arranged at the telescopic end of the electric push rod 3. The push plate 5 has two but not limited to two length dimensions. As a power source, the electric push rod 3 can drive the push plate 5 to move through its telescopic action. The push plate 5, as a component that directly contacts and pushes the baby diaper 8, plays a key role in the sheet arranging process. At the same time, the push plate 5 has two or more length dimensions. This setting takes into account different processing and transportation requirements. The longer push plate 5 can adapt to the pushing of more diapers, ensuring that it can completely cover and stably push the diaper during the pushing process; while the shorter push plate is suitable for a smaller number of diapers, avoiding unnecessary waste or interference during the pushing process.

[0037] Refer to Figure 1 , the product detection sensor 4 is a photoelectric sensor, and its model is: Omron E3Z-D61, which is used to detect the transportation quantity and speed of the baby diaper 8. During the production and packaging process of the baby diaper 8, it is crucial to ensure the accuracy of the transportation quantity and the stability of the speed. The photoelectric sensor can non-contact detect the presence of the diaper by emitting and receiving light, thereby realizing the accurate counting of the transportation quantity. At the same time, the sensor can also real-time monitor the transportation speed of the diaper. This function is crucial for maintaining the smoothness and coordination of the production line. By accurately measuring the speed, the production control system can timely adjust the working rhythm of each link to ensure the synchronization and high efficiency of the entire production process.

[0038] The implementation principle of the present utility model is as follows: First, the feeding unit 9 is located at the front end of the packaging machine body 1 and is connected to the front-end baby diaper 8 production line. The single-piece diaper product lies flat and directly enters the feeding unit 9 of the packaging machine after being output from the production line, and enters the sheet arranging unit 2 vertically after a 90° flip. As the sheet arranging unit 2 transports a plurality of diapers, the electric push rod 3 pushes a row of baby diapers 8 from the sheet arranging unit 2 to the next process according to the number of sheets set by the program;

[0039] A product detection sensor 4 is installed at the middle position of the feeding unit 9 to detect parameters such as the product feeding speed and the distance between adjacent two products.

[0040] When the feeding speed does not exceed 450 pieces per minute, the data collected by the product detection sensor 4 installed on the feeding unit 9 is directly transmitted to the PLC in the electrical system. After calculation, the action instruction is transmitted to the servo controller. Driven by the servo controller, the servo motor of the sheet sorting unit 2 makes corresponding actions, driving the sheet sorting unit 2 to rotate a certain distance in the specified direction, completing the cooperation between the feeding unit 9 and the sheet sorting unit 2, and realizing stable feeding.

[0041] When the product feeding speed needs to reach 650 pieces per minute, the data collected by the product detection sensor 4 in the middle of the feeding unit 9 cannot match the requirements of high-speed operation, which will cause a cooperation error in mechanical movement. On the other hand, high-speed feeding will cause interference between the edges of the diaper products and the belt system 6 of the feeding unit 9, causing the diaper products to deviate from the original movement trajectory. Under the influence of these two factors, the feeding process of some diaper products fails, and the diapers will be blocked at the connection between the feeding unit 9 and the sheet sorting unit 2, resulting in a shutdown phenomenon. To solve this problem, a blowing unit 7 is added at the connection between the feeding unit 9 and the sheet sorting unit 2. Through an external air pump, high-pressure air flow is blown to the surface of the diaper through a trachea and a nozzle, applying a certain wind pressure to ensure that the diaper products can smoothly reach the sheet sorting unit 2 under high-speed feeding conditions. Through the control of the control center, the sheet sorting unit 2 can quickly make corresponding actions according to the movement instruction and cooperate with the feeding unit 9 to successfully realize the high-speed feeding function.

[0042] A second solution is provided for this application. As a second embodiment, as Figure 3 、 Figure 4 shown, by setting two groups of belt systems 6, when multiple baby diapers 8 are transported, the two groups of belt systems 6 can be used to clamp and transport them. According to Figure 3 、 Figure 4 , as the baby diapers 8 are gradually transported, their horizontal transportation can be changed to vertical transportation and cooperate with the subsequent sheet sorting unit 2 to place multiple baby diapers 8 in the corresponding limiting grooves 23, completing the sorting and transportation of multiple baby diapers 8. In this embodiment, the clamping and transportation of the baby diapers 8 by the two groups of belt systems 6 can improve the transportation stability of the baby diapers 8 and enhance their transportation and sorting rates.

[0043] In this application, the specific model and type of the product detection sensor 4 are used as the prior art in the content of this utility model, so no more details will be described here.

[0044] Parts not involved in the present utility model are the same as or can be implemented by using the prior art, and will not be elaborated herein.

The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not make creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
