Description

[0002] With the rapid development of technology, people's living standards have been steadily improving, and people's health has become the primary issue in today's society. For many patients, the intake methods of injection and oral medications may not meet their own needs. Therefore, with the advancement of research, a third method of drug intake has gradually emerged - transdermal patch administration. This method involves evenly coating the drug on a roll material and then packaging it through corresponding technological processes. When a patient needs to use it, they only need to apply it to the skin surface of the body. The drug comes into close contact with the skin and is absorbed by the patient through the skin to treat various diseases. To enable the drug to be fully absorbed, some patches are also equipped with customized wetting agents to fully exert the therapeutic effect of the drug.

Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments described in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] It should be noted that all directional indications (such as up, down, left, right, front, back, top, bottom) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly. In addition, the term "vertical" as used in the embodiments of the invention and the claims refers to an angle of 90° between two elements or a deviation of -5° to +5°, and the term "parallel" refers to an angle of 0° between two elements or a deviation of -5° to +5°.

[0029] In the embodiments of the present invention, descriptions such as "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0030] See Figure 1 and Figure 2 , embodiments of the present invention provide a material packaging device, which may include, for example, a conveying device 10 and a first feeding mechanism 110, a second feeding mechanism 210, a material receiving mechanism 300, a film combining mechanism 330, and a sealing mechanism 400 that are sequentially arranged along the first conveying direction of the conveying device 10.

[0031] The conveying device 10 may be, for example, a conveyor belt. The first feeding mechanism 110 is used to place the first material on the conveying device 10, the second feeding mechanism 210 is used to stack the second material and the first material on the conveying device 10, and the material receiving mechanism 300 is used to receive the first material and the second material conveyed by the conveying device 10 and convey them onto the lower packaging film. The first material may be, for example, a non-conductive planar flexible sheet, such as a medical patch, and the second material may be, for example, a liquid bag or a solid bag, such as accessories like a wetting agent. The material receiving mechanism 300 is used to receive the first material and the second material conveyed by the conveying device 10 and convey them onto the lower packaging film. The film combining mechanism 330 is used to wrap the first material and the second material between the upper packaging film and the lower packaging film, and the sealing mechanism 400 is used to seal the upper packaging film and the lower packaging film.

[0032] The material packaging device provided by the embodiments of the present invention is provided with a conveying device 10 and a first feeding mechanism 110, a second feeding mechanism 210, a material receiving mechanism 300, a film combining mechanism 330, and a sealing mechanism 400 that are sequentially arranged along the first conveying direction of the conveying device 10. The first material and the second material can be stacked on the conveying device 10 through the first feeding mechanism 110 and the second feeding mechanism 210. The conveying device 10 is used to convey the first material and the second material. The stacked first material and second material are received by the material receiving mechanism 300 onto the lower packaging film, and then the first material and the second material are wrapped in the upper packaging film and the lower packaging film through the film combining mechanism 330 and the sealing mechanism 400. The material receiving mechanism 300 can convey multiple materials to the packaging film at high speed, which can improve production efficiency.

[0033] As Figure 1 shown in Fig. 1 or Fig. 2, in one aspect of this embodiment, a material bin is provided on the conveying device 10, and the first material and the second material are sequentially placed in each material bin.

[0034] As Figure 2As shown, in another implementation of this embodiment, the material receiving mechanism 300 may be disposed, for example, adjacent to the end of the conveying device 10. The material receiving mechanism 300 may include, for example, a bracket, on which a steering mechanism for the lower packaging film is provided. The material receiving mechanism 300 is docked with the conveying device 10. By controlling the traction mechanism, the movement speed of the lower packaging film at the docking position is made consistent with the movement speed of the conveying device 10, so that when multiple materials on the conveying device 10 are transferred to the material receiving mechanism 300, they can remain stable without relative displacement, and thus the stacked first material and second material are conveyed to the material receiving mechanism 300 together. As Figure 1 As shown, in one implementation of this embodiment, the material receiving mechanism 300 may further include a conveyor belt disposed below the conveying device 10. The stacked first material and second material are conveyed to the material receiving mechanism 300 together. The materials enter onto the lower packaging film after being buffered by the conveyor belt, so that the materials on the conveying device 10 remain stable during the transfer process without relative displacement. Of course, this embodiment is not limited thereto.

[0035] Furthermore, the material packaging device further includes a first electrostatic attachment device 120. The first electrostatic attachment device 120 is disposed on the conveying device 10 and before the material receiving mechanism 300. The first electrostatic attachment device 120 is used to apply static electricity to the first material or the second material, or to the stacked first material and second material, so as to avoid relative movement of the first material and the second material due to the difference in their movement speeds during the process of being transferred from the conveying device 10 to the material receiving mechanism 300, and thus prevent the occurrence of position offset, thereby further improving problems such as poor packaging caused by offset during the material packaging process. In one implementation of this embodiment, the first electrostatic attachment device 120 is disposed between the first feeding mechanism 110 and the second feeding mechanism 210. The first electrostatic attachment device 120 is used to apply static electricity to the first material so that the first material is charged with static electricity. When the second feeding mechanism 210 stacks the second material on the first material, the static electricity on the first material can adsorb the second material. In another implementation of this embodiment, the first electrostatic attachment device 120 may be disposed, for example, beside the second feeding mechanism 210. The first electrostatic attachment device 120 is used to apply static electricity to the second material so that the second material is charged with static electricity. When the second feeding mechanism 210 stacks the second material on the first material, the static electricity on the second material can directly adsorb the second material onto the first material. In yet another implementation of this embodiment, the first electrostatic attachment device 120 may be disposed, for example, between the second feeding mechanism 210 and the material receiving mechanism 300. The first electrostatic attachment device 120 is used to apply static electricity to the stacked first material and second material, so that the first material and the second material are adsorbed together due to electrostatic induction. And because the first electrostatic attachment device 120 is relatively close to the material receiving mechanism 300, the electrostatic adsorption effect is better.

[0036] Further, the material packaging device may also include a first detection mechanism 130, a first feeding mechanism 140, a second detection mechanism 220, and a second feeding mechanism 230. The first detection mechanism 130 is disposed after the first feeding mechanism 110, the first feeding mechanism 140 is disposed after the first detection mechanism 130, the second detection mechanism 220 is disposed after the second feeding mechanism 210, and the second feeding mechanism 230 is disposed after the second detection mechanism 220. The first detection mechanism 130 is used to detect whether there is a shortage of materials on the conveyor 10. The first feeding mechanism 140 is used to supplement the first material to the conveyor 10 when the first detection mechanism 130 detects a shortage of materials. The second detection mechanism 220 is used to detect whether there is a shortage of materials on the conveyor 10. The second feeding mechanism 230 is used to supplement the second material to the conveyor 10 when the second detection mechanism 220 detects a shortage of materials. The first detection mechanism 130 and the second detection mechanism 220 may be, for example, material shortage sensors. The conveyor 10 may be provided with a grid for placing materials. When the material shortage sensor detects a shortage of materials, the corresponding feeding mechanism replenishes the materials. By providing the first detection mechanism 130, the first feeding mechanism 140, the second detection mechanism 220, and the second feeding mechanism 230, the shortage of materials can be avoided, thereby reducing the defective rate of material packaging.

[0037] The material packaging device provided in this embodiment may also include a second electrostatic attachment device 320. The second electrostatic attachment device 320 is disposed between the material receiving mechanism 300 and the film combining mechanism 330. The second electrostatic attachment device 320 is used to apply static electricity to attach the stacked first material, second material, and packaging film together. For example, before the materials reach the film combining mechanism 330, the first material and the second material are attached to the lower packaging film, and / or after passing through the film combining mechanism 330, the first material and the second material are attached between the upper and lower packaging films. The material packaging device may also include a film releasing mechanism. The film releasing mechanism may include a first film releasing mechanism 311 and a second film releasing mechanism 312. The first film releasing mechanism 311 is used to release the lower packaging film, and the second film releasing mechanism 312 is used to release the upper packaging film. By providing the second electrostatic attachment device 320, the stacked first material, second material, and lower packaging film can be adsorbed together, thereby effectively reducing the relative movement between the first material and the second material and between the first material, the second material, and the lower packaging film during the film combining process of the lower packaging film and the upper packaging film, and further improving problems such as packaging defects caused by offset and misalignment during the material packaging process.

[0038] In one implementation of this embodiment, as Figure 1As shown, the second static electricity attaching device 320 can be arranged, for example, behind the film feeding mechanism, specifically, it can be placed behind the first film feeding mechanism 311. The second static electricity attaching device 320 is used to apply static electricity to the lower packaging film, so that when the stacked first material and second material are conveyed onto the lower packaging film, the static electricity will adsorb the stacked first material, second material and the lower packaging film. In another implementation manner of this embodiment, the second static electricity attaching device 320 can be arranged, for example, on the material receiving mechanism 300, as Figure 2 shown, the second static electricity attaching device 320 can apply static electricity to the stacked first material and second material, so that when the stacked first material and second material enter the material receiving mechanism 300, the static electricity will adsorb the stacked first material, second material and the lower packaging film, and / or after passing through the film combining mechanism 330, the static electricity will attach the first material and second material between the upper and lower packaging films.

[0039] In this embodiment, the material packaging device can also include a material clamping detection mechanism 500, which is arranged behind the sealing mechanism 400 and is used to detect the packaged material products to remove unqualified products. See Figure 3 , the material clamping detection mechanism 500 includes a base 510, rollers 520, a transmission shaft 530 and an abnormality detection device 540. The rollers 520 are connected to the base 510, and the rollers 520 can rotate relative to the base 510. The transmission shaft 530 is connected to the base 510 and is located above the rollers 520. A product transmission space is formed between the transmission shaft 530 and the rollers 520, and the product transmission space is used to convey the material products along the second transmission direction. The transmission shaft 530 can rotate relative to the base 510 and can move in a direction perpendicular to the second transmission direction. A convex portion is provided on the transmission shaft 530 corresponding to the sealing area of the material product, and the abnormality detection device 540 is connected to the transmission shaft 530. When the packaged material product passes through the product transmission space along the second transmission direction, if there is a situation of material clamping in the sealing area of the material product, the material on the sealing area will abut against the convex portion on the transmission shaft 530, so that the transmission shaft 530 moves upward, triggering the abnormality detection device 540.

[0040] Furthermore, see Figure 4 and Figure 5 , the abnormality detection device 540 includes a guide rod 541 and an abnormality sensor 542. The guide rod 541 is connected to the transmission shaft 530, and the guide rod 541 can change with the change of the position of the transmission shaft 530. The abnormality sensor 542 is connected to the guide rod 541, and the abnormality sensor 542 is used to generate an abnormality signal when the guide rod 541 moves and contacts the abnormality sensor 542. Through the setting of the abnormality sensor 542, the user can be reminded to remove unqualified products. The abnormality sensor 542 can be, for example, a gravity sensor or a distance measuring sensor.

[0041] See Figure 6 In addition, an embodiment of the present invention further provides a material packaging method, which is applied to the above-mentioned material packaging device. Specifically, the material packaging method may, for example, include the following steps:

[0042] S11, Stack the first material and the second material on the conveying device;

[0043] S13, The conveying device conveys the first material and the second material to the material receiving mechanism;

[0044] S15, The material receiving mechanism transports the first material and the second material onto the lower packaging film;

[0045] S17, The film combining mechanism combines the lower packaging film and the upper packaging film and seals them through the sealing mechanism to obtain a sealed material product.

[0046] See Figure 7 Furthermore, before step S11 of stacking the first material and the second material on the conveying device, it further includes:

[0047] S10, Apply static electricity to the first material or the second material through the first static electricity attaching device;

[0048] Before step S15 where the material receiving mechanism transports the first material and the second material onto the lower packaging film, it further includes:

[0049] S14, Apply static electricity to the stacked first material and second material through the second static electricity attaching device, or apply static electricity to the lower packaging film through the second static electricity attaching device.

[0050] See Figure 8 After step S11 of stacking the first material and the second material on the conveying device, it further includes:

[0051] S21, Detect whether there is any abnormality in the first material and the second material on the conveying device;

[0052] S22, When it is detected that the first material or the second material is missing, supplement the first material or the second material to the conveying device.

[0053] See Figure 9 After step S17 where the film combining mechanism combines the lower packaging film and the upper packaging film and seals them through the sealing mechanism, it further includes:

[0054] S30, Detect whether the material product is correctly sealed through the material clamping detection mechanism.

[0055] The material packaging method provided by the embodiment of the present invention stacks the first material and the second material on the conveying device 10 through the first feeding mechanism 110 and the second feeding mechanism 210, for example. The conveying device 10 conveys the first material and the second material to the receiving mechanism 300. The receiving mechanism 300 receives the stacked first material and second material onto the lower packaging film. Then, through the film combining mechanism 330 and the sealing mechanism 400, the first material and the second material are wrapped in the upper packaging film and the lower packaging film. By using the receiving mechanism 300 to quickly transport multiple materials onto the packaging film, the production efficiency can be improved. Secondly, the first detection mechanism 130 detects whether there is a lack of material on the conveying device 10, and the first replenishing mechanism 140 replenishes the first material onto the conveying device 10 when the first detection mechanism 130 detects a lack of material; the second detection mechanism 220 detects whether there is a lack of material on the conveying device 10, and the second replenishing mechanism 230 replenishes the second material onto the conveying device 10 when the second detection mechanism 220 detects a lack of material, so as to avoid the shortage of materials and reduce the defective rate of material packaging. In addition, the first electrostatic application device 120 applies static electricity to the first material or the second material, so that the first material and the second material can be adsorbed together, which can further improve the material transportation efficiency of the receiving mechanism 300, and can also prevent the first material and the second material from shifting during transportation, resulting in position deviation, thereby improving problems such as packaging defects caused by offset and misalignment during the material packaging process. The second electrostatic application device 320 can make the stacked first material, second material and the lower packaging film adsorb together, so that when the lower packaging film covers the upper packaging film, the first material and the second material will not separate from the lower packaging film, thereby further improving problems such as packaging defects caused by offset and misalignment during the material packaging process. The clamped material detection mechanism 500 detects the packaged material products, and the unqualified products can be removed.

[0056] To facilitate the understanding of the material packaging device and the material packaging method provided in this embodiment, the following gives an exemplary illustration of the material packaging process, where the first material is a medical patch and the second material is a wetting agent.

[0057] The medical patches are loaded onto the conveying device 10 in a double row of medical patches. When the first detection mechanism 130 detects a lack of medical patches, the first replenishing mechanism 140 replenishes the medical patches into the corresponding grids of the conveying device 10 to ensure that each grid in the double row of the conveying device 10 has a medical patch.

[0058] During the transfer of the patch, the first electrostatic device 120 will electrostatically charge the patch, and then the second loading mechanism 210 will load the double-row wetting agent to the middle and upper part of the corresponding patch. The loading of the wetting agent can be, for example, by placing the produced wetting agent on the clip by the wetting agent production equipment, and then transporting a certain number of clips to the clip transfer station by the clip transport trolley, and then transporting the clips to the wetting agent loading position by the lifting mechanism to wait for the second loading mechanism 210, such as a loading robot, to pick up the material; when a box of clip wetting agent is used up, it is then transported to the empty clip recovery trolley through the clip transfer station.

[0059] After the wetting agent is loaded, when the second detection mechanism 220 detects that there is a shortage of material at the second loading mechanism 210, the second feeding mechanism 230 will replenish the material at the corresponding grid where the wetting agent is missing. After the replenishment is completed, the medicine patch and the wetting agent arrive at the receiving mechanism 300 together, and the medicine patch and the wetting agent are transferred to the corresponding position of the lower packaging film together.

[0060] The packaging film can be completed, for example, by a film unwinding mechanism, and can be completed, for example, at a packaging film unwinding station. First, the packaging film is rolled up at the unwinding station (the upper and lower packaging films are printed together), and then passes through the film splicing platform, the unwinding correction station, and the unwinding traction station to reach the unwinding slitting station, and the packaging film is divided into two; the upper packaging film passes through the ultraviolet laser coding station, the 90° corner station (upper), the coding detection station, and the upper packaging film correction station to reach the film joining station; the lower packaging film passes through the 90° corner station (lower), the lower packaging film adjustment station, the lower packaging film traction station, the tension detection station, and the lower packaging film correction station to reach the material splicing mechanism 300.

[0061] The lower packaging film is first electrostatically charged by the second electrostatic charging device 320, and then the material receiving mechanism 300 transfers the patch and the wetting agent to the corresponding position of the lower packaging film, and arrives at the film bonding station to bond the upper and lower packaging films. After the upper and lower packaging films bond the patch and the wetting agent, they are packaged at the four-side sealing station, and then the patch is tested by the material clamping detection mechanism 500 at the material clamping detection station, and then the product is delivered to the cross-cutting station after passing through the traction station for easy tear line cutting and packaging film cross-cutting. The finished product is delivered to the negative pressure belt station after passing through the vacuum negative pressure receiving net belt station for transportation and transfer, and after passing through three sensor detections and two waste rejection processes, the finished product flows to the next production process, the cartoning machine, for outer packaging, and the unqualified products rejected by the negative pressure belt station are collected through the waste collection box.

[0062] In addition, it can be understood that the aforementioned embodiments are only exemplary descriptions of the present invention. Under the premise that the technical features do not conflict, the structures do not contradict, and the purpose of the present invention is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used in combination.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
