[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] The core of this invention is to provide a folding system that can improve folding efficiency.

[0046] For a specific embodiment of the folding system provided by this utility model, please refer to the following: Figures 1 to 13 It includes a conveying device 2, a support rod 4, and a material folding pusher 5.

[0047] The top of the conveying device 2 has a conveying surface 22, which can convey products along the first direction X and pass through the lifting station 13 and the folding station 14 in sequence.

[0048] It should be noted that the first direction X refers to a single direction, and product 6 moves from the starting end to the ending end along the conveyor surface 22 in the first direction X. Figure 1 In the diagram, the first direction X refers to the positive direction indicated by the X-arrow.

[0049] To meet production needs, in some embodiments, in the folding system, the product 6 is conveyed along the first direction X by the conveying surface 22, passing sequentially through the loading station 11, the sorting station 12, the lifting station 13, the folding station 14 and the unloading station 15.

[0050] It should be noted that the product 6 used in the embodiments of this application is generally a bag-shaped product, specifically a powder-liquid dual-chamber bag for ease of description. Correspondingly, the loading station 11, the sorting station 12, the folding station 14, and the unloading station 15 are, respectively, the bag loading station, the bag sorting station, the bag folding station, and the bag unloading station. However, this should not be construed as a limitation on the product 6 applicable to this application; it could also be other products 6 that require folding.

[0051] The powder-liquid dual-chamber bag is a fully enclosed infusion preparation structure. Drug powder and injectable solvent are placed in two separate bags within the same package using a welded joint technique. These two bags are designated as a liquid chamber (61) and a powder chamber (62), separated by a welded joint (63). The liquid chamber (61) and powder chamber (62) are used to hold the liquid and powder respectively. Before use, a gentle press opens both chambers, allowing for fully enclosed aseptic preparation without the need for a dedicated preparation area. After folding (at the welded joint (63)), the difficulty of opening the welded joint (63) is increased, facilitating transportation and ensuring complete isolation of the liquid and powder before mixing.

[0052] It should be noted that the two ends of the conveying surface 22 in the width direction Y are the head end and the tail end, respectively. After the product 6 is placed on the conveying surface 22, for a powder-liquid dual-chamber bag, its two separate bags are arranged sequentially along the width direction Y of the conveying surface 22, with the side closer to the head end of the conveying surface 22 being the head end of the product 6, and the side closer to the tail end of the conveying surface 22 being the tail end of the product. In this embodiment, unless otherwise specified, the width direction Y refers to the width direction of the conveying surface 22.

[0053] like Figure 8 and Figure 9 As shown, the support rod 4 is used to lift the head end of the product 6 on the conveying surface 22, so that the head end of the product 6, which is laid flat on the conveying surface 22, is gradually lifted up and separated from the conveying surface 22, and forms a certain angle with the tail end of the product 6.

[0054] At least a portion of the support rod 4 is located at the lifting station 13, specifically, it can be entirely located at the lifting station 13. The support rod 4 is located at the head end of the conveyor surface 22. The support rod 4 extends along the first direction X, and along the first direction X, as shown... Figure 8 As shown, the distance between the top surface of the support rod 4 and the conveying surface 22 gradually increases, and, as... Figure 9 As shown, it gradually approaches the tail end of the conveying surface 22 in the first direction X. In this embodiment, the support rod 4 lifts the bag body, which serves as the liquid cavity 61, upward, while the bag body, which serves as the powder cavity 62, remains flat on the conveying surface 22.

[0055] like Figure 11 As shown, the folding pusher 5 is used to push the head end of the product 6 off the support rod 4, so that it can swing and fold over the tail end, specifically so that the liquid cavity 61 folds over the powder cavity 62.

[0056] The folding pusher 5 is located at the folding station 14 and at the head end of the conveyor surface 22. The output end of the folding pusher 5 is retractable, so as to push the head end of the product 6 through the retractable movement.

[0057] For example, the output end of the folding pusher 5 is a folding telescopic mechanism, which can be a cylinder, a hydraulic cylinder, or a push rod connected to the piston rod of the cylinder or hydraulic cylinder; it can also be a combination structure of a motor and a linear module, or a screw and nut assembly. In addition, the telescopic movement of the folding telescopic mechanism relative to the support rod 4 in the width direction Y can be a direct movement in the width direction Y, or it can have a component movement in the width direction Y.

[0058] It should be noted that the support rod 4 and the folding pusher 5 can be arranged sequentially along the first direction X, or the support rod 4 can extend to the folding station 14, and the folding pusher 5 can push the head end of the product 6 from above the support rod 4.

[0059] In this embodiment, the folding system places the product 6 on the conveying surface 22 and conveys it along the first direction X. During the conveying process, the head end of the product 6 moves onto the support rod 4 and gradually rises along the support rod 4, which is inclined relative to the conveying surface 22, until the head end of the product 6 is lifted a certain distance from the conveying surface 22. Similarly, the part of the product 6 near its head end flips upward at a certain angle relative to the part near its tail end. Then, the head end of the product 6 is pushed by the folding pusher 5 to realize the folding of the product 6, thereby realizing the automated folding of the product 6, which can improve the folding efficiency and reduce the labor intensity of the workers.

[0060] Furthermore, such as Figure 8 and Figure 9 As shown, the end of the support rod 4 in the first direction X (corresponding to) Figure 8 The right end of the support rod 41 is fixed to the top of the support rod 41, and the bottom end of the support rod 41 is fixed to the base plate 42. Specifically, the support rod 41 gradually moves downwards in the width direction Y away from the conveying surface 22, so that the top of the support rod 41 below the support rod 4 has a certain clearance in the width direction Y, avoiding interference of the support rod 41 with the product 6. In addition, the base plate 42 extends along the width direction Y and extends towards the conveying surface 22 from the position where it connects with the bottom end of the support rod 41. In addition, the support rod 4 can be fixed to the bracket 9 below or on the side of the conveying device.

[0061] Furthermore, such as Figure 1 As shown, the conveying device 2 includes an annular conveying body and a drive device for driving the conveying body to move in an annular manner. At this time, the top of the conveying body is the conveying surface 22. The conveying body can be a conveyor belt or a conveyor chain.

[0062] Specifically, the conveying body can operate once at regular intervals, and the conveying surface 22 can convey a certain distance at regular intervals; or, the conveying surface 22 can always be in the process of conveying, and the speed can change or remain constant.

[0063] Furthermore, such as Figure 5 As shown, the folding system also includes a guide rod 8, specifically a round rod, used to position and guide the product 6 as it moves on the conveyor surface 22. The guide rod 8 can be fixed to the bracket 9.

[0064] Among them, such as Figure 1As shown, the guide rod 8 is located above the conveying surface 22 and in the middle of the conveying surface 22 in the width direction. There is a clamping gap between the guide rod 8 and the conveying surface 22. The guide rod 8 extends along the first direction X. After the product 6 is placed on the conveying surface 22, the two parts of the product 6 in the width direction are located on both sides of the guide rod 8. Specifically, the two bag bodies of the product 6 are located on both sides of the guide rod 8. The middle joint position of the two bag bodies of the product 6 (specifically, the poor weld 63) is clamped between the guide rod 8 and the conveying surface 22, located in the clamping gap.

[0065] In some embodiments, the guide rod 8 extends along the first direction X and passes at least through the material handling station 12 and the lifting station 13. For example, the guide rod 8 extends from the material handling station 12 to the folding station 14, and its starting end may also partially extend to the loading station 11. After the product 6 is loaded at the loading station 11 and enters the material handling station 12, the clamping gap clamps the two separate bags of the product 6. Typically, the two separate bags on both sides of the guide rod 8 protrude upward relative to the guide rod 8, thereby achieving the positioning and constraint of the product 6 by the guide rod 8 in the width direction.

[0066] In some embodiments, such as Figure 1 and Figure 5 As shown, along the first direction X, the starting segment of the guide rod 8 in the first direction X ( Figure 5 The clamping gap between the leftmost segment of the guide rod 8 and the conveying surface 22 gradually decreases, and the clamping gap between the remaining part of the guide rod 8 and the conveying surface 22 can be the same, so that the product 6 that has just entered the clamping gap can be guided by the starting segment of the guide rod 8 and the conveying surface 22.

[0067] Furthermore, the folding system also includes multiple clamps 21, each clamp 21 being sequentially fixed on the conveying surface 22 along the first direction X. Compared to relying solely on the friction between the product 6 and the conveying surface 22 for conveying, adding clamps 21 to fix the product 6 can improve the stability of the conveying. Optionally, the clamps 21 are evenly arranged on the conveying surface 22.

[0068] Specifically, to improve the compatibility between the clamp 21 and the guide rod 8, and the reliability of fixing the product 6, such as Figures 2 to 4 As shown, the clamp 21 includes a plurality of grippers arranged sequentially along the width direction Y, specifically including a first gripper 214 and a second gripper 215. Each gripper has a feeding area for accommodating at least a portion of the structure of the product 6.

[0069] When the clamp 21 passes the guide rod 8, such as Figure 4As shown, the first gripper 214 and the second gripper 215 are located on both sides of the guide rod 8 in the width direction Y. At this time, the first gripper 214 and the second gripper 215 respectively clamp the two bags of product 6, which can ensure that the middle part is roughly aligned with the guide rod 8 in the first direction X, so as to facilitate smooth entry into the clamping gap.

[0070] In some embodiments, such as Figure 2 As shown, the clamp 21 includes a fixed plate 211 and a baffle plate 212, wherein the two baffle plates 212 cooperate to form a gripper. In the gripper, the two baffle plates 212 are arranged sequentially along the first direction X, and a portion of the structure of the product 6 is located between the two baffle plates 212 of the gripper to position the product 6 in the first direction X and determine the synchronization with the operation of the conveyor surface 22.

[0071] It should be noted that the grippers position the product 6 in the first direction X. Specifically, no clamping force in the first direction X may be applied to the product 6 to avoid damage. In this case, the spacing between the grippers in the first direction X can be equal to or slightly larger than the size of the corresponding bag body in the first direction X, as long as it ensures that the product 6 can move forward with the conveyor surface 22. Of course, in other embodiments, the grippers can also hold the product 6 to improve the anti-detachment effect.

[0072] In some embodiments, such as Figure 2 As shown, the baffle plate 212 includes a vertical plate 216 perpendicular to the conveying surface 22 and a guide ramp 217 disposed at the top of the vertical plate 216. The distance between the guide ramps 217 of the two baffle plates 212 in the gripper gradually increases upward in the first direction X, so as to facilitate the insertion of the product 6 into the gripper.

[0073] In some embodiments, such as Figure 3 and Figure 4 As shown, the feeding area of ​​the clamp 21 is arranged through the width direction Y. Specifically, the two baffles 212 of each clamp are arranged through the width direction Y, and the clamp 21 no longer has a constraint structure at both ends in the width direction Y. This simplifies the structure of the clamp 21, while allowing the product 6 to be freely adjusted in the width direction Y to match the fine adjustment of the guide rod 8, or to be unloaded from the clamp 21 via the width direction Y.

[0074] In some embodiments, such as Figure 3As shown, the bottom end of the baffle plate 212 has an adjusting plate 218 located below the fixed plate 211. The fixed plate 211 has an elongated hole 213 extending along the first direction X, and the adjusting plate 218 is bolted to the elongated hole 213. Since the position of the adjusting plate 218 in the elongated hole 213 along the first direction X is adjustable, the distance between the two baffle plates 212 in the gripper in the first direction X can be adjusted, so that the clamp 21 can be adapted to the bag shape of the product 6 with different sizes in the first direction X.

[0075] In some embodiments, the fixing plate 211 can be bolted to the conveying surface 22; it can also be fixed by snap-fitting, adhesive bonding or other methods.

[0076] Furthermore, to improve the regularity of product 6 conveying, the folding system also includes a limiting device 3. The limiting device includes a limiting strip disposed at the head and / or tail end of the conveying surface 22 in the width direction. The limiting strip extends along the first direction X and passes at least through the material handling station 12 and the lifting station 13, thereby positioning the product 6 at at least one end in the width direction Y.

[0077] It should be noted that the guide rod 8 and the limit bar perform the relevant functions of product 6 at the selected workstation, but they are stationary relative to the ground and do not move along the first direction X with the conveyor surface 22. Specifically, they can be fixed on the bracket 9 for support.

[0078] Specifically, such as Figure 4 and Figure 6 As shown, the limiting bar includes a head-end limiting rod 31 disposed at the head end of the conveying surface 22. The head-end limiting rod 31 has a limiting groove 311 facing the tail end of the conveying surface 22. The head end of the product 6 can extend into the limiting groove 311 and be supported and guided by the limiting groove 311. The head end of the product 6 can be a tube 611, and the limiting groove 311 constrains the tube 611 from the upper and lower sides and from one side in the width direction Y.

[0079] Specifically, such as Figure 4 As shown, the starting end of the limiting groove 311 in the first direction X ( Figure 4 The left end of the middle section is provided with an inclined surface, which gradually approaches the tail end of the conveying surface 22 in the width direction along the first direction X, and has a guiding effect on the head end of the product 6 in the width direction Y, gradually pushing the product 6 toward the tail end of the conveying surface 22.

[0080] Specifically, such as Figure 9 As shown, in the first direction X, the starting end of the support rod 4 is connected to the end of the head end limiting rod 31, specifically below the head end limiting rod 31. In addition, the starting end of the support rod 4 and the end of the head end limiting rod 31 can be arranged sequentially in the width direction Y along the tail end direction close to the conveying surface 22, so that the product 6 directly enters the area above the support rod 4 as soon as it leaves the limiting groove 311.

[0081] Specifically, such as Figure 7 As shown, the limiting strip includes a tail-end limiting baffle 32 located at the tail end of the conveyor surface 22, which guides and limits the product 6 by adhering to the tail end of the product 6. The distance between the tail-end limiting baffle 32 and the lateral bottom of the limiting groove 311 can be equal to the length of the product 6 in the width direction Y to ensure the limiting effect. The tail-end limiting baffle 32 can extend sequentially along the first direction X at the loading station 11, the sorting station 12, the lifting station 13, and the folding station 14.

[0082] Specifically, such as Figure 1 As shown, a cantilever 81 is also fixed on the tail end limiting baffle 32, and the guide rod 8 is fixed to the bottom end of the cantilever 81, so that the guide rod 8 is suspended above the conveying surface 22.

[0083] Furthermore, such as Figure 1 As shown, the folding system also includes a feeding device 7 located at the feeding station 15 for the continued conveying of the product 6 after folding at the folding station 14.

[0084] Specifically, such as Figure 13 As shown, the unloading device 7 includes an unloading pusher 71 located at the head end of the conveying surface 22 in the width direction Y, which pushes the product 6 toward the tail end of the conveying surface 22, thereby automating the unloading process and the separation of the product 6 from the conveying surface 22.

[0085] For example, the output end of the feeding pusher 71 is a bag pushing telescopic mechanism, which can be a cylinder, hydraulic cylinder or other structure; it can also be a combination structure of motor and linear module or screw and nut assembly.

[0086] For example, such as Figure 13 As shown, to improve the reliability of material feeding, the bag pushing telescopic mechanism extends and retracts along the width direction, and a feeding plate 711 is fixed at one end of the bag pushing telescopic mechanism near the tail end of the conveying surface 22. After the feeding plate 711 extends downward to the conveying surface 22, it can be in close contact with the conveying surface 22 or have a very small gap, such as a gap of 1mm or 0.5mm, to ensure that the feeding plate 711 can contact and push the product 6. In addition, during feeding, the conveying surface 22 can pause conveying, and the feeding plate 711 can move along the width direction Y toward the corresponding clamp 21, directly pushing the product 6 out of the clamp 21.

[0087] Specifically, such as Figure 13As shown, the unloading device 7 also includes an unloading conveyor belt 72 that abuts the tail end of the conveying surface 22 in the width direction Y. That is, the unloading pusher 71 pushes the product 6 from the conveying surface 22 onto the unloading conveyor belt 72, and the product 6 continues to be conveyed to the next process via the unloading conveyor belt 72. In some embodiments, the unloading conveyor belt 72 can be an annular belt that conveys the product 6 in the width direction away from the conveying surface 22.

[0088] Furthermore, a robotic arm can be installed at the loading station 11 to automatically load the product 6 from the previous process to the fixture 21 at the loading station 11 on the conveying surface 22. In other embodiments, manual loading can also be used.

[0089] To ensure sufficient loading time, the loading station 11 can correspond to at least two clamps 21. Specifically, the loading station 11 has the length of two clamps 21 in the first direction X, which can ensure that at least one clamp 21 is used for loading during the conveying process of the conveying surface 22, thus ensuring sufficient loading time.

[0090] The folding system in this embodiment is used in the pharmaceutical packaging equipment industry in some implementations, specifically in the post-packaging process of powder-liquid dual-chamber bags, where the powder-liquid dual-chamber bag is a medicine bag. The process includes the following steps:

[0091] First, a manual or robotic arm places the powder-liquid double-chamber bag onto the clamp 21 of the feeding station 11 of the folding system to complete the bag feeding. In the width direction Y, the mouth tube 611 of the medicine bag is located at the head end of the conveying surface 22, and the tail end of the medicine bag abuts against the tail end limiting baffle 32 and is placed in close contact with the tail end limiting baffle 32, or a distance of about 1mm is reserved between the medicine bag and the tail end limiting baffle 32.

[0092] Subsequently, during the conveying process on the conveyor surface 22, the medicine bags enter the sorting station 12 for sorting. At the sorting station 12, the limiting groove 311 provides a width-direction limiting effect on the opening tube 611. At this time, if the medicine bag is relatively close to the head end of the conveyor surface 22, it can also be sorted along the width direction Y to the position where the tail end of the medicine bag is against the tail end limiting baffle 32, so that in the first direction X, the medicine bags in each clamp 21 are flat and their positions in the clamp 21 are basically uniform. Furthermore, guide rods 8 are set at the sorting station 12. The lower part of the guide rods 8 is close to the poor weld 63 in the middle of the medicine bag. While limiting the medicine bag, it does not affect the conveying of the medicine bag. The guide rods 8 extend all the way to the folding station 14.

[0093] Afterwards, when the medicine bag reaches the lifting station 13, the head end of the medicine bag disengages from the head end limiting rod 31 and continuously climbs on the top surface of the support rod 4. The support rod 4 can support the mouth tube 611 of the medicine bag, or it can support the connection between the mouth tube 611 and the liquid chamber 61. The support rod 4 slowly lifts the liquid chamber 61 of the powder-liquid double chamber bag, so that the medicine bag changes from a horizontal lying state to a state in which the powder chamber 62 and the liquid chamber 61 are at a certain angle, such as vertical or close to vertical.

[0094] Then, when the medicine bag reaches the last medicine bag position on the support rod 4, at least part of the structure enters the folding station 14. With the liquid cavity 61 supported by the end of the support rod 4, the folding pusher 5 pushes the liquid cavity 61, specifically in a horizontal direction, so that the liquid cavity 61 and the powder cavity 62 are folded together, thus completing the bag folding. At this time, the liquid cavity 61 of the medicine bag presses against the powder cavity 62. Under the limitation of the guide rod 8 above the poor weld 63, the liquid cavity 61 will not be misaligned in a large direction, and there are also baffles 212 on both sides of the clamp 21 to limit the misalignment of the liquid cavity 61.

[0095] Afterwards, the conveyor 22 continues to convey the medicine bag, which arrives at the unloading station 15. At this point, the medicine bag has been folded in half, and the folded medicine bag has detached from the tail end limiting baffle 32 and the guide rod 8 above the welded section. That is, the unloading station 15 no longer has the tail end limiting baffle 32 and the guide rod 8. The unloading pusher 71 pushes the folded medicine bag from the clamp 21 onto the unloading conveyor belt 72, completing the unloading process. The folding system then completes the entire process. After the medicine bag arrives on the unloading conveyor belt 72, it continues to be conveyed until it docks with the downstream equipment.

[0096] The folding system in this embodiment solves the problem of low folding efficiency for the current product 6, specifically addressing issues such as misalignment, poor aesthetics, and inability to fit into plastic film packaging, thereby reducing labor costs. This equipment features a compact structure, stable operation, low cost, aesthetically pleasing folding, high operating efficiency, and fast speed. It can effectively interface with upstream and downstream equipment, achieving integrated packaging functionality across the entire production line and improving production efficiency.
