Description

Technical Field

[0001] This invention relates to the field of pharmaceutical packaging equipment technology, and more particularly to a packaging device. Background Technology

[0002] Cardboard box packaging is a common packaging method in industries such as pharmaceuticals and cosmetics. With the continuous development of automation, the application of automatic carton sealing machines is becoming increasingly widespread. Automatic carton sealing machines can fold cardboard into boxes. To improve material packaging efficiency, a one-piece cartoning process has been further developed, which involves initially folding the cardboard into a semi-enclosed box blank, inserting the material into the box blank, and then folding the unclamped cardboard on the box blank to form a fully enclosed packaging box, i.e., sealing the box. However, in existing automatic carton sealing machines, the sealing operation still needs to be performed at the workstation, and the box can only be conveyed to the subsequent process after sealing, resulting in low efficiency. Summary of the Invention

[0011] In some embodiments, the second drive assembly includes a second drive member, a second connecting rod, and a second connecting portion. The second drive member is fixed to the mounting assembly. One end of the second connecting rod is rotatably connected to the output end of the second drive member. The other end of the second connecting rod is rotatably connected to one end of the second connecting portion. The other end of the second connecting portion is connected to the end sealing clamp. The other end of the second connecting portion is rotatably connected to the mounting assembly on the side facing the mounting assembly.

[0012] In some embodiments, there are multiple sealing clamps, which are spaced apart along a first direction, and the end sealing plates of the multiple sealing clamps are all located on the same side of the transfer drive assembly.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0040] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0041] It should also be noted that the division of multiple embodiments in this invention is merely for the convenience of description and should not constitute a special limitation. Features in various embodiments can be combined and referenced in each other without contradiction. In the accompanying drawings, X indicates the first direction and Y indicates the second direction.

[0042] In a one-piece cartoning process, cardboard is gradually folded into a semi-enclosed box blank along a conveyor line, and materials are placed into the semi-enclosed box blank during the folding process. After the materials are fed in, the semi-enclosed box blank needs to be further folded to make it a fully enclosed cardboard box 5 for transfer to subsequent processes. However, existing automatic carton sealing machines often require the semi-enclosed box blank to be completely folded into a fully enclosed cardboard box 5 at the workstation before transfer, which is inefficient.

[0043] Based on this, see Figures 1 to 10 This invention provides a packaging device 1, which includes a first conveying device 3 and a sealing device 2.

[0044] The first conveying device 3 is used to convey the cardboard box 5. A conveying clamp 31 is provided on the first conveying device 3 to hold the cardboard box 5. The conveying clamp 31 is open in the arrangement direction of the two sides 521 of the assembled box. The conveying clamp 31 holds the front and rear end faces of the cardboard box 5 so that the cardboard box 5 can remain stable during the movement of the first conveying device 3. It is understood that the cardboard box 5 has different forms, such as a cardboard form, a semi-enclosed box blank form, and a fully enclosed cardboard box 5 form. During the process of gradually folding the cardboard box 5 from the cardboard form to the fully enclosed cardboard box 5 form, the individual structures of the cardboard box 5 do not change; rather, the relative folding between the individual structures occurs, that is, the relative positions change. The cardboard box 5 held by the conveying clamp 31 is in the first form, i.e., the semi-enclosed form, which has an open opening to be enclosed. See, for example... Figure 8 The cardboard box 5 includes a box cover 51 and a box body 52. ​​The box body 52 has two oppositely arranged side surfaces 521 and a first end surface 522 and a second end surface 523 oppositely arranged. The box cover 51 includes a main cover 513, two side wings 511, and an end 512. The main cover 513 is connected to the first end surface 522 of the box body 52. ​​The two side wings 511 are located on both sides of the main cover 513. The end 512 is connected to the side of the main cover 513 away from the connection point with the box body 52.

[0045] The sealing device 2 is used to output the paper box 5 from the first conveying device 3. The sealing device 2 includes a transfer drive assembly 30 and a sealing clamp 20, which are connected to each other. The sealing clamp 20 includes a side sealing mechanism 22 and an end sealing mechanism 23. The side sealing mechanism 22 is used to bend the two side wings 511 of the box cover 51 to clamp the paper box 5. The transfer drive assembly 30 is used to drive the sealing clamp 20 to move after the side sealing mechanism 22 clamps the paper box 5. The end sealing mechanism 23 is used to bend the end 512 of the box cover 51 when the sealing clamp 20 moves. The sealing device 2 clamps the paper box 5 through the sealing clamp 20, and the transfer drive assembly 30 drives the sealing device 2 to move, thereby transferring the paper box 5 from the first conveying device 3 to other processes. Since the conveying clamp 31 is arranged in the direction of the two sides 521 of the box body 52, that is, in the lateral direction of the paper box 5, the conveying clamp 31 is open to form an opening, so it can avoid the side sealing mechanism 22, reduce the obstruction of the side sealing mechanism 22 when bending the side wing 511, and help improve the sealing efficiency of the paper box 5.

[0046] A specific implementation of this invention is as follows, see below. Figures 7 to 10 The first conveying device 3, for example, has a transfer station where a first-form cardboard box 5, held by a conveying clamp 31, is conveyed. The transfer drive assembly 30 drives the sealing clamp 20 to move and contact the main cover plate 513, thereby bending the main cover plate 513 relative to the box body 52. ​​The two side wings 511 and the end 512 of the main cover plate 513 rotate relative to the box body 52 as the main cover plate 513 bends, folding the cardboard box 5 into a second form. Then, the lateral sealing mechanism 22 of the sealing clamp 20 bends the two side wings 511, folding them relative to the main cover plate 513, and causing the two side wings 511 to contact the side surface 521 of the box body 52, folding the cardboard box 5 into a third form. In the third configuration, the two opposing side wings 511 are folded and contact the sides 521 of the box body 52. ​​Therefore, the lateral sealing mechanism 22 clamps the third configuration box 5 from the opposing side wings 511, and the conveying fixture 31 releases its grip on the third configuration box 5. The transfer drive assembly 30 drives the sealing fixture to move, thereby moving the third configuration box 5 away from the first conveying device 3. As the box 5 moves to the subsequent process, the end sealing mechanism 23 bends the end 512 of the box cover 51, causing the end 512 to bend relative to the main cover 513, thus contacting the second end face 523 of the box body 52. ​​The box 5 is further folded into a fourth configuration, i.e., a fully enclosed box 5. When the box 5 is conveyed to the subsequent process, it is in the fourth configuration, i.e., the fully enclosed configuration, meaning the box 5 is sealed.

[0047] The packaging equipment 1 provided in this embodiment of the invention uses a conveying clamp 31 to hold a cardboard box 5, allowing the cardboard box 5 to be transported by a first conveying device 3. The conveying clamp 31 is openly arranged in the arrangement direction of the two sides 521 of the box body 52, thereby avoiding the movement of the side sealing mechanism 22, making the movement of the side sealing mechanism 22 smoother, and helping to improve the folding, sealing and transfer efficiency of the cardboard box 5. The packaging equipment 1 provided in this embodiment of the invention can clamp the cardboard box 5 after folding the side wings 511 for transfer, and fold the end 512 of the box cover 51 during the transfer process to complete the sealing of the cardboard box 5, which can effectively save time, improve the sealing and transfer efficiency of the cardboard box 5, and improve the efficiency of the packaging equipment 1.

[0048] In some embodiments, see Figure 7 and Figure 10 The sealing clamp 20 also includes an installation assembly 21. The side sealing mechanism 22 includes a first drive assembly 221 and two side sealing clamps 222. The two sides 521 are arranged along a first direction. The two side sealing clamps 222 are located on opposite sides of the installation assembly 21 along the first direction. The first drive assembly 221 is installed on the installation assembly 21 and connected to the two side sealing clamps 222. The first drive assembly 221 is used to drive the two side sealing clamps 222 to bend the two side wings 511 of the box cover 51 to contact the side 521 of the box body 52. When the side wing 511 is bent, the lateral sealing clamp 222 contacts and abuts against the side wing 511. After the first-state cardboard box 5 is bent into the second-state cardboard box 5 by the sealing clamp 20 driven by the transfer drive component, the first drive assembly 221 drives the two lateral sealing clamps 222 to abut against the side wing 511 respectively, thereby bending the side wing 511 to transform the second-state cardboard box 5 into the third-state cardboard box 5. The two sides 521 of the box body 52 are arranged along the first direction, so that after the side wing 511 is bent and contacts the side wing 511 of the box body 52, the two lateral sealing clamps 222 apply pressure to the two side wing 511 on opposite sides of the first direction to clamp the third-state cardboard box 5. Then the transfer drive assembly 30 can drive the sealing clamp 20 to move to transfer the third-state cardboard box 5. The plate-like structure of the side sealing clamp 222 has a large contact area with the side wing 511, which helps to distribute pressure so that the force applied by the side sealing clamp 222 to the side wing 511 is more uniform, which helps to reduce the chance of damage to the side wing 511 when folding.

[0049] In some embodiments, see Figure 7 and Figure 10The end sealing mechanism 23 includes a second drive assembly 231 and an end sealing clamp 232. The end sealing clamp 232 is located between two side sealing clamps 222. The second drive assembly 231 is mounted on the mounting assembly 21 and connected to the end sealing clamp 232. The second drive assembly 231 is used to drive the end sealing clamp 232 to bend the end 512 of the box cover 51 to contact the second end face 523 of the box body 52. ​​When bending the end 512, the end sealing clamp 232 contacts and abuts against the end 512. The second-state paper box 5 is bent by the side wings 511 by the side sealing clamp 222 to become the third-state paper box 5. After being further clamped by the side sealing clamp 222, the transfer drive assembly 30 drives the sealing clamp 20 to move, thereby driving the third-state paper box 5 to be transferred. During the transfer process, the second drive assembly 231 drives the end sealing clamp 232 to abut against the end 512, thereby bending the end 512 so that the end 512 contacts the second end face 523 of the box body 52, thus transforming the third-state paper box 5 into the fourth-state paper box 5. The plate-like structure of the side sealing clamp 222 has a large contact area with the side wing 511, which helps to distribute pressure, so that the force applied by the side sealing clamp 222 to the side wing 511 is more uniform, which helps to reduce the probability of damage to the side wing 511 during folding.

[0050] Specifically, see Figure 7 , Figure 10 and Figure 11The end sealing mechanism 23 further includes an end fixing clamp 233, which abuts against the first end face 522. The end fixing clamp 233 is fixed to the mounting assembly 21 and is located on opposite sides of the end sealing clamp 232 along the second direction of the mounting assembly 21. The first direction is perpendicular to the second direction. The first end face 522 and the second end face 523 are located on opposite sides of the box body 52 along the second direction. It is understandable that when the end sealing clamp 232 bends the end 512, a force needs to be applied to the end 512 in the second direction. However, since only the lateral sealing clamp 222 applies a force to the paper box 5 in the first direction during the transfer process, when the end sealing clamp 232 bends the end 512, in the second direction, in addition to the force applied by the end sealing clamp 232, there is only the frictional force of the lateral sealing clamp 222 on the paper box 5. Therefore, when the end sealing clamp 232 bends the end 512, the paper box 5 may move in the second direction, resulting in poor bending effect, or even causing the paper box 5 to fall off the sealing clamp 20. Thus, by providing an end fixing clamp 233 opposite to the end sealing clamp 232 in the second direction, the end fixing clamp 233 can abut against the second end face 523. When the end sealing clamp 232 applies a force in the second direction to the end 512 so that the end 512 contacts the first end face 522, the end fixing clamp 233 can limit the second end face 523 and apply the opposite force, thereby preventing the cardboard box 5 from moving in the second direction, reducing the probability of the cardboard box 5 falling off, and helping to improve the bending effect of the end 512.

[0051] In some specific embodiments, see Figure 1 and Figure 5 The top of the conveying clamp 31 is spaced apart from one end of the box cover plate 51 that connects to the first end face 522. That is, the gripper of the conveying clamp 31, which abuts against the first end face 522 in the second direction, is spaced apart from the top of the first end face 522. In this way, the conveying clamp 31 leaves a portion on one side of the top of the first end face 522, so that when the conveying clamp 31 clamps the paper box 5, the end fixing plate 233 can also abut against the first end face 522, thereby facilitating the sealing clamp 20 to seal and clamp the paper box 5.

[0052] In some specific embodiments, see Figure 1 and Figure 6The conveying clamp 31 includes a push rod 32, which pushes the cardboard box 5 to move in a first direction away from the grippers of the conveying clamp 31 that are positioned opposite the first end face 522 in the first direction. When the sealing clamp 20 seals the cardboard box 5 held in the conveying clamp 31, the push rod 32 pushes the cardboard box 5 to move, thereby creating a gap between the grippers of the conveying clamp 31 that are opposite the first end face 522 and the first end face 522. The end fixing plate 233 can be inserted into the gap to abut against the first end face 522 to facilitate subsequent sealing. In this way, the grippers of the conveying clamp 31 that are opposite the first end face 522 can increase the contact area with the first end face 522, which helps to make the force applied by the grippers to the first end face 522 more even, thereby reducing the probability of damage to the cardboard box 5 during clamping.

[0053] In some embodiments, see Figure 7 , Figure 10 and Figure 11The sealing clamp 20 also includes a top sealing clamp 24. The mounting assembly 21 includes a mounting plate 211. A first drive assembly 221 and a second drive assembly 231 are mounted on a first side of the mounting plate 211. The top sealing clamp 24 is connected to a second side of the mounting plate 211. An end sealing clamp 232 and a side sealing clamp 222 are located on the second side. That is, the mounting plate 211, the end sealing clamp 232, and the side sealing clamp 222 are located on the other side of the first drive assembly 221 and the second drive assembly 2311 relative to the mounting portion. The sealing clamp 20 seals and clamps the box body 52 on the second side. When the transfer drive assembly 30 drives the sealing clamp 20 to bend the cardboard box 5 in the first state, the top sealing clamp 24 abuts against the main cover plate 513. Then, the transfer drive assembly 30 further drives the conveying clamp 31 to move toward the box body 52, causing the top sealing clamp 24 to bend, thereby changing the cardboard box 5 in the first state to the second state. Understandably, when the top sealing clamp 24 abuts against the main cover plate 513 to bend the main cover plate 513, the top sealing clamp 24, for example, first abuts against the main cover plate 513 through one end in the second direction. During the bending process, the contact area with the main cover plate 513 is gradually increased, and after bending, it is positioned opposite to the main cover plate 513 to limit its movement. In this way, by setting the top sealing clamp 24, the sealing clamp 20 can abut against the box cover plate 51 more smoothly, and at the same time, it helps to disperse the force applied to the box cover plate 51 by the sealing clamp 20, preventing the box cover plate 51 from being damaged by interference from other components. Specifically, for example, the conveying drive assembly first drives the sealing clamp 20 to move to the side of the first end face 522 away from the paper box 5 in the second direction. The conveying drive assembly drives the sealing clamp 20 to move from the first end face 522 to the second end face 523, so that the top sealing clamp 24 abuts against the side of the box cover 51 of the paper box 5 in the second state that is on the same side as the first end face 522 in the second direction. The top sealing clamp 24 then moves in the direction from the first end face 522 to the second end face 523 to bend the box cover 51.

[0054] Specifically, see Figure 7 , Figure 10 and Figure 11 The sealing clamp 20 also includes an elastic element 25, which is connected between the mounting plate 211 and the top sealing clamp 24. The top sealing clamp 24 is directly driven by the transfer drive assembly 30. In this way, the elastic element 25 can change the force applied by the transfer drive assembly 30, thereby helping to reduce the probability of damage to the box cover 51 when bending.

[0055] Further, see Figure 7 , Figure 10 and Figure 11The elastic element 25 is, for example, a spring, with its two ends connected to the mounting plate 211 and the cover plate 51, respectively. The spring can extend and retract, allowing the top sealing clamp 24 to tilt during bending of the main cover plate 513. This increases the contact area between the top sealing clamp 24 and the main cover plate 513, improving bending performance. Furthermore, the spring's extension and retraction further enhances the cushioning effect, thus reducing the likelihood of damage to the cover plate 51 during bending. Multiple springs can be used to balance the force and displacement at different positions on the top sealing clamp 24, further reducing the probability of damage to the cover plate 51 during bending.

[0056] In some embodiments, see Figure 7 , Figure 10 and Figure 11 The first drive assembly 221 includes a first drive member 2211, a first connecting rod 2212 and a first connecting part 2213. The first drive member 2211 is fixed to the mounting assembly 21. One end of the first connecting rod 2212 is rotatably connected to the output end of the first drive member 2211. The other end of the first connecting rod 2212 is rotatably connected to one end of the first connecting part 2213. The other end of the first connecting part 2213 is connected to the side sealing clamp 222. The other end of the first connecting part 2213 is rotatably connected to the mounting assembly 21 on the side facing the mounting assembly 21. When bending the side wing 511, the output end of the first driving member 2211 moves, one end of the first connecting rod 2212 rotates relative to the output end, and simultaneously the first connecting rod 2212 moves with the output end, thereby causing the other end of the first connecting rod 2212 to rotate relative to the first connecting part 2213, and causing one end of the first connecting part 2213 to move with the first connecting rod 2212. Since the other end of the first connecting part 2213 is rotatably connected to the mounting assembly 21, after one end of the first connecting part 2213 moves with the first connecting rod 2212, the first connecting part 2213 rotates around the other end of the first connecting part 2213, thereby driving the lateral sealing clamp 222 to rotate, so as to achieve bending and clamping of the side wing 511. In this way, the rotation of the lateral sealing clamp 222 is achieved through the connecting rod assembly, which has a simple structure, low cost, and stable and controllable movement. Specifically, each side sealing clamp 222 is provided with a first connecting rod 2212 and a first connecting part 2213; for example, the two first connecting rods 2212 are connected to the same first driving member 2211, which helps to save space and facilitate synchronization; or, for example, the two connecting rods are respectively connected to two first driving members 2211, which helps to reduce mutual interference.

[0057] Specifically, see Figure 7 , Figure 10 and Figure 11The first drive assembly 221 also includes a first connector 2214. The middle part of the first connector 2214 is connected to the output end of the first drive assembly 2211, and the opposite ends of the first connector 2214 are rotatably connected to one end of each of the two first connecting rods 2212. The first drive assembly 2211 drives the first connector 2214, thereby further driving the two first connecting rods 2212 to move simultaneously. In this way, the two lateral sealing clamps 222 can be rotated synchronously, so that the side wings 511 can be bent and clamped synchronously. This helps to prevent one side of the lateral sealing clamp 222 from being over-clamped while the other side of the lateral sealing clamp 222 is too loose, which could cause the cardboard box 5 to fall off or be damaged.

[0058] For some specific embodiments, see Figure 7 , Figure 10 and Figure 11 The second drive assembly 231 includes a second drive member 2311, a second connecting rod 2313, and a second connecting part 2314. The second drive member 2311 is fixed to the mounting assembly 21. One end of the second connecting rod 2313 is rotatably connected to the output end of the second drive member 2311. The other end of the second connecting rod 2313 is rotatably connected to one end of the second connecting part 2314. The other end of the second connecting part 2314 is connected to the end sealing clamp 232. The other end of the second connecting part 2314 is rotatably connected to the mounting assembly 21 on the side facing the mounting assembly 21. When bending end 512, the output end of the second driving member 2311 moves, one end of the second connecting rod 2313 rotates relative to the output end, and simultaneously the second connecting rod 2313 moves with the output end, thereby causing the other end of the second connecting rod 2313 to rotate relative to the second connecting portion 2314, and causing one end of the second connecting portion 2314 to move with the second connecting rod 2313. Since the other end of the second connecting portion 2314 is rotatably connected to the mounting assembly 21, after one end of the second connecting portion 2314 moves with the second connecting rod 2313, the second connecting portion 2314 rotates around the other end of the second connecting portion 2314, thereby driving the end sealing clamp 232 to rotate, so as to achieve bending of end 512. In this way, the rotation of the end sealing clamp 232 is achieved through the connecting rod assembly, which has a simple structure, low cost, and stable and controllable movement.

[0059] Specifically, see Figure 11 The second drive assembly 231 may also include a second connector 2312, one end of which is fixed to the output end of the second drive assembly 2311, and the other end of which is rotatably connected to the second connecting rod 2313. Thus, transmission via the second connector 2312 facilitates the connection between the second connecting rod 2313 and the second drive assembly 2311.

[0060] In some specific embodiments, see Figure 11The mounting assembly 21 also includes multiple protective plates 212, which are connected to the first side of the mounting plate 211. These protective plates 212 are sequentially connected and, together with the mounting plate 211, enclose an mounting space. The first driving member 2211 and the second driving member 2311 are disposed within this mounting space. Thus, the protective plates 212 protect the first driving member 2211 and the second driving member 2311 from damage due to external collisions during movement. For example, the protective plates 212 may have through holes to facilitate the connection of the first driving member 2211 and the second driving member 2311 to the first connecting rod 2212 and the second connecting rod 2313, respectively.

[0061] In some embodiments, see Figure 12 There are multiple sealing clamps 20, which are arranged at intervals along the first direction, and the end sealing plates 232 of the multiple sealing clamps 20 are all located on the same side of the transfer drive assembly 30. "Multiple" refers to two or more. That is, the multiple sealing clamps 20 have the same installation orientation on the transfer drive assembly 30, and the transfer drive assembly 30 can drive the multiple sealing clamps 20 to move synchronously, so that multiple paper boxes 5 can be transferred simultaneously each time, thereby improving the efficiency of paper box 5 transfer.

[0062] Specifically, see Figures 1 to 4 See Figure 12 The packaging equipment 1 also includes a second conveying device 4. The first conveying device 3 has a first conveying direction, and the second conveying device 4 has a second conveying direction. The first and second conveying directions are parallel to the first direction. In this way, the transfer drive assembly 30 does not need to rotate during the transfer process, which helps to increase the speed at which the transfer drive assembly 30 drives the sealing clamp 20 to move, thereby improving the transfer efficiency. Furthermore, during the transfer process, multiple sealing clamps 20 can simultaneously pick up rows of cartons 5 from their corresponding conveying clamps 31, and then seal them during the transfer process. They can also simultaneously place rows of cartons 5 in the fourth state on the second conveying device 4.

[0063] In some specific embodiments, the first conveying device is provided with multiple stations in sequence along the first conveying direction. The multiple stations perform different processes, thereby folding the cardboard into a first state of cardboard box 5 and accommodating the material in cardboard box 5.
