[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] The core of the present invention is to provide a folding material system, which can improve the folding efficiency.

[0046] For the first specific embodiment of the material folding system provided by the present invention, please refer to Figures 1 to 13 , which includes a conveying device 2, a supporting rod 4, and a material folding pusher 5.

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

[0048] It should be noted that the first direction X refers to a single direction, and the product 6 moves on the conveying surface 22 from the starting end to the ending end along the first direction X with the conveying surface 22. In Figure 1 the illustrated orientation, the first direction X refers to the positive direction indicated by the arrow of the direction X.

[0049] To meet the production requirements, in some embodiments, in the material folding system, the product 6 sequentially passes through the loading station 11, the material arranging station 12, the lifting station 13, the material folding station 14, and the unloading station 15 along the first direction X with the conveying of the conveying surface 22.

[0050] It should be noted that the product 6 used in the embodiments of the present application is usually a bag-shaped product. For the convenience of description, it is specifically a powder-liquid double-chamber bag. Correspondingly, the loading station 11, the material arranging station 12, the material folding station 14, and the unloading station 15 are sequentially the bag loading station, the bag arranging station, the bag folding station, and the bag unloading station. However, it should not be construed as a limitation on the product 6 applicable to the present application, and it can also be other products 6 with folding requirements.

[0051] Among them, the powder-liquid double-chamber bag is a fully enclosed infusion preparation structure. The drug powder and the injection solvent are placed in two sub-bag bodies of the same package through the virtual welding technology. The two sub-bag bodies are respectively a liquid chamber 61 and a powder chamber 62, which are separated by the virtual welding point 63. The liquid chamber 61 and the powder chamber 62 of the powder-liquid double-chamber bag are respectively used to place the liquid medicine and the medicine powder. When in use, gently pressing can open the liquid chamber 61 and the powder chamber 62, and the fully enclosed aseptic preparation can be realized without a special preparation place. After the powder-liquid double-chamber bag undergoes the material folding operation (folding at the virtual welding point 63), the opening difficulty of the virtual welding point 63 can be increased, which is convenient for transportation and can ensure that the liquid medicine and the medicine powder are in a completely isolated state before mixing.

[0052] It should be noted that the two ends in the width direction Y of the conveying surface 22 are respectively the head end and the tail end. After the product 6 is placed on the conveying surface 22, for the powder-liquid double-chamber bag, its two sub-bag bodies are sequentially arranged along the width direction Y of the conveying surface 22, and the side close to the head end of the conveying surface 22 is the head end of the product 6, and the side close to the tail end of the conveying surface 22 is the tail end of the product 6. In the embodiments of the present application, unless otherwise specifically stated, the width direction Y refers to the width direction of the conveying surface 22.

[0053] Such asFigure 8 and Figure 9 As shown in Figure 9 , the supporting 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 lying flat on the conveying surface 22 is gradually lifted, separated from the conveying surface 22, and forms a certain angle with the tail end of the product 6.

[0054] Among them, at least part of the structure of the supporting rod 4 is arranged at the lifting station 13, and specifically, it can be completely arranged at the lifting station 13. The supporting rod 4 is located at the head end of the conveying surface 22. The supporting rod 4 extends along the first direction X, and along the first direction X, as Figure 8 shown, the distance between the top surface of the supporting rod 4 and the conveying surface 22 gradually increases, and, as Figure 9 shown, it gradually approaches the tail end of the conveying surface 22 in the first direction X. In this embodiment, the supporting rod 4 lifts the bag dividing body of the liquid cavity 61 upward, while the bag dividing body of the powder cavity 62 always lies flat on the conveying surface 22.

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

[0056] Among them, the folding material pusher 5 is arranged at the folding station 14 and at the head end of the conveying surface 22. The output end of the folding material pusher 5 can move telescopically to push the head end of the product 6 through the telescopic movement.

[0057] Exemplarily, the output end of the folding material pusher 5 is a folding telescopic mechanism, and specifically, structures such as a cylinder, a hydraulic cylinder, etc. can be selected, or a push rod connected to the piston rod of the cylinder or the hydraulic cylinder; a motor and a linear module, or a matching structure of a lead screw nut assembly can also be selected. In addition, the telescopic movement of the folding telescopic mechanism relative to the supporting rod 4 in the width direction Y can specifically be a direct movement in the width direction Y, or have a sub-movement in the width direction Y.

[0058] It should be noted that the supporting rod 4 and the folding material pusher 5 can be arranged in sequence along the first direction X, or the supporting rod 4 also extends to the folding station 14, and the folding material pusher 5 pushes the head end of the product 6 from above the supporting rod 4.

[0059] In the material folding system of this embodiment, the product 6 is placed on the conveying surface 22 and conveyed along the first direction X. During the conveying process, after the head end of the product 6 moves onto the supporting rod 4, it gradually rises along the supporting rod 4 that 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 close to its head end is flipped upward by a certain angle relative to the part close to its tail end. Then, the head end of the product 6 is pushed by the material folding pusher 5, enabling the folding of the product 6, thus realizing the automatic material folding of the product 6, improving the material folding efficiency, and reducing the labor intensity of the staff.

[0060] Further, as Figure 8 and Figure 9 shown, the end of the supporting rod 4 in the first direction X (corresponding to the right end in the Figure 8 orientation) is fixed to the top end of the supporting inclined rod 41, and the bottom end of the supporting inclined rod 41 is fixed to the bottom plate 42. Specifically, the supporting inclined rod 41 gradually moves away from the conveying surface 22 downward in the width direction Y, so that there is a certain avoidance space at the top of the supporting inclined rod 41 below the supporting rod 4 in the width direction Y to avoid the supporting inclined rod 41 interfering with the product 6. In addition, the bottom plate 42 extends along the width direction Y and extends from the position where it is docked with the bottom end of the supporting inclined rod 41 towards the conveying surface 22. In addition, the supporting rod 4 can be fixed to the bracket 9 below or on the side of the conveying device.

[0061] Further, as Figure 1 shown, the conveying device 2 includes an annular conveying main body and a driving device for driving the annular movement of the conveying main body. At this time, the top of the conveying main body is the conveying surface 22. The conveying main body can be a conveyor belt or a conveyor chain.

[0062] Specifically, the conveying main body can run once every certain period of time, so that the conveying surface 22 conveys a certain distance every certain period of time; or, the conveying surface 22 can always be in the conveying process, and the speed can change or remain unchanged.

[0063] Further, as Figure 5 shown, the material folding system further includes a guiding rod 8, specifically a round rod, which is used to position and guide the movement of the product 6 on the conveying surface 22. The guiding rod 8 can be fixed to the bracket 9.

[0064] Among them, as Figure 1As shown, the guide rod 8 is disposed above the conveying surface 22 and is located 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, and 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 respectively located on both sides of the guide rod 8. Specifically, it means that the two sub-bag bodies of the product 6 are respectively located on both sides of the guide rod 8, and the middle docking position (specifically, it can be the soldering spot 63) of the two sub-bag bodies of the product 6 is clamped between the guide rod 8 and the conveying surface 22 and is located in the clamping gap.

[0065] In some embodiments, the guide rod 8 extends along the first direction X and at least passes through the sorting station 12 and the lifting station 13. For example, the guide rod 8 extends from the sorting station 12 to the folding station 14, and the starting end can also partially extend to the feeding station 11. After the product 6 is loaded at the feeding station 11 and enters the sorting station 12, the clamping gap clamps between the two sub-bag bodies of the product 6. Generally, the two sub-bag bodies on both sides of the guide rod 8 bulge upward relative to the guide rod 8, so as to realize the positioning and constraint of the product 6 by the guide rod 8 in the width direction.

[0066] In some embodiments, as Figure 1 and Figure 5 shown, along the first direction X, the clamping gap between the starting section of the guide rod 8 in the first direction X ( Figure 5 the leftmost section in the orientation) 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 starting section of the guide rod 8 and the conveying surface 22 can play a guiding role for the product 6 just entering the clamping gap.

[0067] Furthermore, the folding system further includes a plurality of jigs 21, and each jig 21 is fixedly arranged in sequence along the first direction X on the conveying surface 22. Compared with only relying on the friction between the product 6 and the conveying surface 22 for conveying, adding the jigs 21 to fix the product 6 can improve the stability of conveying. Optionally, each jig 21 is evenly arranged on the conveying surface 22.

[0068] Specifically, to improve the adaptability of the jig 21 to the guide rod 8 and the reliability of fixing the product 6, as Figures 2 to 4 shown, the jig 21 includes a plurality of jaws arranged in sequence along the width direction Y, specifically, it can include the first jaw 214 and the second jaw 215. Each jaw has a material placing area for accommodating at least part of the structure of the product 6.

[0069] When the jig 21 passes by the guide rod 8, as Figure 4As shown, the first jaw 214 and the second jaw 215 are respectively located on both sides of the guide rod 8 in the width direction Y. At this time, the first jaw 214 and the second jaw 215 respectively clamp two sub-bag bodies of the product 6, which can ensure that the middle part is generally aligned with the guide rod 8 in the first direction X, facilitating smooth entry into the clamping gap.

[0070] In some embodiments, as Figure 2 shown, the fixture 21 includes a fixing plate 211 and a stop plate 212. Among them, two stop plates 212 cooperate to form a jaw. In the jaw, the two stop plates 212 are arranged in sequence along the first direction X, and a part of the structure of the product 6 is located between the two stop plates 212 of the jaw to position the product 6 in the first direction X and determine the synchronization with the operation of the conveying surface 22.

[0071] It should be noted that when the jaw positions the product 6 in the first direction X, specifically, it may not apply a clamping force in the first direction X to the product 6 to avoid damage to the product 6. At this time, the distance between the jaws in the first direction X can be equal to or slightly larger than the size of the corresponding sub-bag body in the first direction X, as long as it is ensured that the product 6 can advance with the conveying surface 22. Of course, in other embodiments, the product 6 can also be clamped by the jaws to improve the anti-detachment effect of the product 6.

[0072] In some embodiments, as Figure 2 shown, the stop plate 212 includes a vertical plate 216 perpendicular to the conveying surface 22 and a guiding inclined plate 217 provided at the top of the vertical plate 216. The distance between the guiding inclined plates 217 of the two stop plates 212 in the jaw gradually increases upward in the first direction X, facilitating the placement of the product 6 between the jaws.

[0073] In some embodiments, as Figure 3 and Figure 4 shown, the feeding area of the fixture 21 is provided in a through manner in the width direction Y. Specifically, the space between the two stop plates 212 of each jaw is provided in a through manner in the width direction Y, and no constraint structure is provided at both ends of the fixture 21 in the width direction Y. While simplifying the structure of the fixture 21, in the width direction Y, the product 6 can freely adjust its position on the fixture 21 to match the fine adjustment of the guide rod 8, or can be loaded and unloaded from the fixture 21 in the width direction Y.

[0074] In some embodiments, as Figure 3As shown, the bottom end of the baffle plate 212 has an adjustment plate 218 located below the fixed plate 211, and the fixed plate 211 is provided with a long hole 213 extending along the first direction X, and the adjustment plate 218 is bolted to the long hole 213. Since the position of the adjustment plate 218 in the long hole 213 along the first direction X is adjustable, the distance between the two baffle plates 212 in the clamping jaws in the first direction X can be adjusted, so that the clamp 21 can adapt to the bag types of products 6 with different sizes in the first direction X.

[0075] In some embodiments, the fixing plate 211 may be fixed to the conveying surface 22 by bolts; it may also be fixed by means of clamping, bonding, etc.

[0076] Furthermore, in order to improve the regularity of the conveying of the product 6, the folding system also includes a limiting device 3, which includes a limiting bar arranged at the head end and / or tail end of the conveying surface 22 in the width direction, and the limiting bar extends along the first direction X and passes through at least the material sorting station 12 and the lifting station 13, so as to position 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 functions related to the product 6 at the selected workstation, but are stationary relative to the ground and do not move along the first direction X with the conveying surface 22. Specifically, they can be fixed on the bracket 9 for support.

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

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

[0080] Specifically, 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 limit rod 31, specifically lower than the bottom of the head end limit rod 31. In addition, the starting end of the support rod 4 and the end of the head end limit rod 31 can be arranged in sequence along the tail end direction close to the conveying surface 22 in the width direction Y, so that the product 6 can directly enter the top of the support rod 4 as soon as it leaves the limit groove 311.

[0081] Specifically, as Figure 7 shown, the limiting strip includes a tail-end limiting baffle 32 provided at the tail end of the conveying surface 22, which guides and positions the product 6 by fitting the tail end of the product 6. Among them, the distance between the tail-end limiting baffle 32 and the lateral bottom of the limiting groove 311 can specifically be equal to the length of the product 6 in the width direction Y to ensure the limiting effect. Among them, the tail-end limiting baffle 32 can extend along the first direction X to the folding station 14 at the feeding station 11, the material arranging station 12, and the lifting station 13 in sequence.

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

[0083] Furthermore, as Figure 1 shown, the folding system further includes a blanking device 7 provided at the blanking station 15 for continuously conveying the product 6 after folding at the folding station 14.

[0084] Specifically, as Figure 13 shown, the blanking device 7 includes a blanking pusher 71 provided at the head end of the conveying surface 22 in the width direction Y to push down the product 6 toward the tail end of the conveying surface 22, so as to realize the automation of the product 6 detaching from the conveying surface 22 during the blanking process.

[0085] Exemplarily, the output end of the blanking pusher 71 is a bag-pushing telescopic mechanism, and specifically, structures such as a cylinder or a hydraulic cylinder can be selected; a structure combining a motor and a linear module, or a lead screw nut assembly can also be selected.

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

[0087] Specifically, as Figure 13As shown, the blanking device 7 further includes a blanking conveyor belt 72 that is butt - joined to the tail end of the conveying surface 22 in the width direction Y. That is to say, the blanking pusher 71 pushes the product 6 from the conveying surface 22 onto the blanking conveyor belt 72, and the product 6 is continuously conveyed to the next process through the blanking conveyor belt 72. In some embodiments, the blanking conveyor belt 72 can be an endless belt that conveys the product 6 in a direction away from the conveying surface 22 along the width direction.

[0088] Furthermore, at the loading station 11, a manipulator can also be provided to realize the automatic loading of the product 6 from the previous process to the fixture 21 at the loading station 11 of the conveying surface 22. In other embodiments, manual loading can also be used.

[0089] Among them, to ensure sufficient loading time, the loading station 11 can correspond to at least two fixtures 21. Specifically, the loading station 11 has the length of two fixtures 21 in the first direction X, so that during the conveying process of the conveying surface 22, at least one fixture 21 at the loading station 11 can be used for loading, ensuring sufficient loading time.

[0090] In some embodiments, the folding system in this embodiment is used in the pharmaceutical packaging equipment industry and applied to the post - packaging process of powder - liquid double - chamber bags. The powder - liquid double - chamber bag is a medicine bag and includes the following steps:

[0091] First, the powder - liquid double - chamber bag is manually or by a manipulator placed on the fixture 21 at the loading station 11 of the folding system to complete bag loading. Among them, 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 limit baffle 32 and is placed in contact with the tail - end limit baffle 32, or there is a distance of about 1 mm reserved between the tail - end of the medicine bag and the tail - end limit baffle 32.

[0092] Subsequently, during the conveying process of the conveying surface 22, the medicine bag enters the bag - sorting station 12 for bag sorting. At the bag - sorting station 12, a limiting effect in the width direction Y is given to the mouth tube 611 through the limiting groove 311. At this time, if the medicine bag is relatively close to the head end of the conveying surface 22, the medicine bag can also be sorted along the width direction Y to the position where the tail end of the medicine bag abuts against the tail - end limit baffle 32, so that in the first direction X, the medicine bags in each fixture 21 are flat and their positions in the fixture 21 are basically unified. And, a guide rod 8 is started to be set at the bag - sorting station 12. The lower part of the guide rod 8 closely adheres to the virtual welding part 63 in the middle of the medicine bag. While limiting the medicine bag, it does not affect the conveying of the medicine bag, and the guide rod 8 extends all the way to the folding station 14.

[0093] Afterwards, when the medicine bag reaches the supporting 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 supporting rod 4. Herein, the supporting rod 4 can hold the mouth tube 611 of the medicine bag or hold the connection between the mouth tube 611 and the liquid chamber 61. The supporting rod 4 slowly lifts the liquid chamber 61 of the powder-liquid double-chamber bag, causing the medicine bag to change from a horizontal lying state to a state where the powder chamber 62 and the liquid chamber 61 form a certain angle, such as vertical or nearly vertical.

[0094] Then, when the medicine bag reaches the last medicine bag position on the supporting rod 4, at least part of the structure enters the folding station 14. With the liquid chamber 61 being lifted at the end of the supporting rod 4, a folding pusher 5 is used to push the liquid chamber 61, specifically pushing the liquid chamber 61 in the horizontal direction, so that the liquid chamber 61 and the powder chamber 62 are folded against each other, thereby completing the bag folding. At this time, the liquid chamber 61 of the medicine bag presses against the powder chamber 62. Limited by the guiding rod 8 above the virtual welding point 63, the liquid chamber 61 will not be misaligned in a large direction, and there are also baffle plates 212 on both sides of the fixture 21 to limit the misalignment of the liquid chamber 61.

[0095] Afterwards, the conveying surface 22 continues to convey, and the medicine bag reaches the discharging station 15. At this time, the medicine bag has been folded, and the folded medicine bag has disengaged from the tail end limiting baffle 32 at the tail of the medicine bag and the guiding rod 8 above the virtual welding. That is, the discharging station 15 is not provided with the tail end limiting baffle 32 and the guiding rod 8. The folded medicine bag is pushed out from the fixture 21 onto the discharging conveyor belt 72 by a discharging pusher 71 to complete the discharging, and the folding system thus completes the entire process. After the medicine bag reaches the discharging conveyor belt 72, it continues to be conveyed until it reaches the docking point with the downstream equipment.

[0096] The folding system in this embodiment can solve the problem of low folding efficiency of the current product 6, specifically including problems such as folding misalignment, insufficient aesthetics, and inability to be packed in a plastic film. It can reduce labor costs. This device has a compact structure, stable operation, low cost, beautiful folding, high operating efficiency, fast operating speed, and can effectively dock with upstream and downstream equipment to realize the function of packaging integration of the entire production line, improving production efficiency.
