Description

Technical Field

[0001] This utility model relates to the field of powder and liquid dual-chamber soft bag technology, and in particular to a soft bag opening and filling system and a powder and liquid dual-chamber bag dispensing machine. Background Technology

[0002] The powder-liquid dual-chamber soft bag large-volume infusion product is made of non-PVC infusion-specific membrane material, containing infusion fluid and sterile powder. It is convenient and quick to use in clinical practice, and the medication is safe and reliable. It is currently recognized worldwide as the safest and most reliable ready-to-use large-volume infusion product.

[0003] Due to the special nature of soft bags, they need to be hung on a carrier with pins during the conveying process and transported by a conveying mechanism. When hanging the soft bags on the pins, errors may occur, and the soft bags may not be fully hung on the pins, making them easy to fall off. Moreover, when the soft bags are conveyed to the filling station for filling, the bag opening mechanism needs to open the soft bags from both sides. During this process, the soft bags are prone to falling off the pins. Utility Model Content

[0004] The purpose of this utility model is to provide a soft bag opening and filling system and a powder and liquid dual-chamber bag dispensing machine, which solves the problem of soft bags falling off in the prior art.

[0005] This utility model is implemented as follows: a soft bag opening and filling system includes a carrier, a first suction cup, a second suction cup, and a filling mechanism for filling soft bags. The carrier is provided with a bag hanging pin for limiting the soft bag. The first suction cup is located on one side of the bag hanging pin of the carrier, and the second suction cup is located on the other side of the carrier. The feature is that a bag protector is provided on one side of the first suction cup, and the first suction cup and the bag protector share a drive.

[0006] The carrier includes a bag hanger with a bag hanger pin on it. The bag hanger is movable, and the soft bag is stretched into place by the bag hanger pin. When the first and second suction cups open the soft bag from the front and back respectively, the soft bag will cause the bag hanger to move closer together. When the soft bag closes, it unfolds to both sides, and the bag hanger returns to its original position. During this process, the soft bag and the bag hanger will have relative displacement, which can easily cause the soft bag to fall off. In this invention, the first suction cup is located on the side of the carrier where the bag hanger pin is located, and a bag protector is located on the same side as the first suction cup. When the first suction cup moves closer to or away from the soft bag, the bag protector moves synchronously with the first suction cup to limit the soft bag on the bag hanger pin and prevent it from falling off. The bag protector and the first suction cup share a drive, which reduces costs, makes full use of space, avoids interference, and ensures smooth soft bag filling.

[0007] A further technical solution of this utility model is: the protective bag component includes a U-shaped portion, the opening of which faces the soft bag. The U-shaped portion opening facing the soft bag ensures that the soft bag is not interfered with by the protective bag component during opening, and the U-shaped portion allows for connection to the mounting component, resulting in high stability.

[0008] A further technical solution of this utility model is: the protective bag component further includes a clearance portion for avoiding the hanging pin, and the clearance portion is perpendicular to both ends of the U-shaped portion. As the first suction cup approaches the soft bag, the protective bag component simultaneously approaches the soft bag. The protective bag component has a clearance portion for avoiding the hanging pin on the soft bag, allowing the protective bag component to pass through the hanging pin and adhere to the soft bag, thus limiting the position of the soft bag. If the soft bag is not fully hooked into the hanging pin in the previous workstation, the protective bag component of this utility model can also assist the soft bag in hooking into the hanging pin during its movement towards the soft bag.

[0009] A further technical solution of this utility model is that the avoidance part is provided with openings facing both sides of the soft bag. During the opening and closing of the bag, the avoidance part does not affect the opening and closing of the soft bag.

[0010] A further technical solution of this utility model is that the first suction cup is placed in the U-shaped portion. When the first and second suction cups drive the soft bag to open and close, the U-shaped portion can avoid interference with the soft bag.

[0011] A further technical solution of this utility model is: the bag hanging pin is placed on the top of the carrier and faces the first suction cup. The bag hanging pin hangs the bag from both sides of the soft bag fixing part, and the direction of the bag hanging pin is towards the first suction cup. The bag protection part and the first suction cup are on the same side of the mounting part, which can effectively protect the soft bag on the bag hanging pin.

[0012] A further technical solution of this utility model is as follows: the first suction cup is connected to the mounting component, the mounting component is connected to the first drive, and the protective bag component and the first suction cup are placed on the same side of the mounting component. The first drive drives the mounting component to move closer to or away from the soft bag, thereby driving the first suction cup and the protective bag component on the mounting component to move synchronously. Only one first drive is needed to achieve simultaneous movement of the first suction cup and the protective bag component, reducing costs. Moreover, the overall design space of the machine is small and multiple components have relative movement. The design of this utility model can also effectively reduce space and avoid interference.

[0013] A further technical solution of this utility model is: the second suction cup is connected to the second mounting bracket, and the second mounting bracket is connected to the second drive. The second drive drives the second mounting bracket to move closer to or away from the soft bag, so that the second suction cup on the second mounting component moves closer to or away from the soft bag synchronously.

[0014] This utility model also provides a powder-liquid dual-chamber bag filling machine, including a conveyor line, on which the aforementioned soft bag opening and filling system is provided, and the carrier is placed on the conveyor line. The soft bag is placed on the carrier, which can move along the conveyor line. When the carrier moves to the filling station, the soft bag is opened and filled by the soft bag opening and filling system, and then the filled soft bag is conveyed to the next station by the conveyor line to complete the powder-liquid dual-chamber bag filling.

[0015] A further technical solution of this utility model is: the conveyor line is provided with a bag loading station, a packaging material purification station, a cutting station, a first weighing station, a first material dispensing station, a second weighing station, a second material dispensing station, a nitrogen filling station, a sealing station, a third weighing station, a material unloading station, and a bag exiting station in sequence. The first material dispensing station and the second material dispensing station are provided with the soft bag opening and filling system.

[0016] The soft bags sequentially enter the carrier on the conveyor line through the bag-loading station, undergo purification treatment of the carrier and soft bags at the packaging material purification station, have a filling port cut at the cutting station, are weighed at the first weighing station, are filled with the first material through the filling port at the first material dispensing station, have the amount of the first material weighed at the first material weighing station, have the second material filled with the second material through the filling port at the second material dispensing station, are filled with nitrogen at the nitrogen filling station, have the filling port sealed at the sealing station, have the amount of the second material weighed at the second material weighing station, are unloaded from the carrier on the conveyor line at the unloading station, and are transported to the next process at the bag exit station. The bag-opening and filling actions at the first and second material dispensing stations are completed by a soft bag opening and filling system according to this utility model.

[0017] The beneficial effects of this utility model are as follows: In this utility model, the first suction cup is located on the side of the carrier where the bag hanging pin is provided, and a bag protector is provided on the same side as the first suction cup. When the first suction cup approaches or moves away from the soft bag, the bag protector moves synchronously with the first suction cup to limit the soft bag on the bag hanging pin and prevent the soft bag from falling off. The bag protector and the first suction cup share a drive, which reduces costs, makes full use of space and avoids interference, and ensures the smooth filling of soft bags.

[0026] Example 1:

[0027] Figure 1-4A soft bag opening and filling system is shown, including a carrier 1, a first suction cup 23, a second suction cup 33, and a filling mechanism for filling soft bags. The carrier 1 is provided with a hanging pin 11 for limiting the soft bag 5. The first suction cup 23 is provided on one side of the hanging pin 11 of the carrier 1, and the second suction cup 33 is provided on the other side of the carrier 1. A protective bag component 4 is provided on one side of the first suction cup 23. The first suction cup 23 and the protective bag component 4 share a drive.

[0028] In this embodiment, the protective bag component 4 includes a U-shaped portion, the opening of which faces the soft bag 5. The U-shaped portion opening facing the soft bag ensures that the soft bag is not interfered with by the protective bag component during opening, and the U-shaped portion allows for connection to the mounting component, resulting in high stability.

[0029] In this embodiment, the protective bag is fixedly connected to the mounting component via a U-shaped portion.

[0030] In this embodiment, the U-shaped portion is provided with a U-shaped groove for the first suction cup to pass through. The first suction cup is positioned above the protective bag component.

[0031] In this embodiment, the protective bag component 4 further includes a clearance portion 41 for avoiding the hanging pin 11, and the clearance portion 41 is perpendicular to both ends of the U-shaped portion. As the first suction cup approaches the soft bag, the protective bag component simultaneously approaches the soft bag. The protective bag component is provided with a clearance portion to avoid the hanging pin on the soft bag, so that the protective bag component can pass through the hanging pin and fit against the soft bag, thus limiting the position of the soft bag. When the soft bag is not fully hooked into the hanging pin in the previous workstation, the protective bag component in this invention can also assist the soft bag in hooking into the hanging pin during its movement towards the soft bag.

[0032] In this embodiment, the clearance portion 41 has openings facing both sides of the soft bag 5. During the opening and closing of the bag, the clearance portion does not affect the opening and closing of the soft bag.

[0033] In this embodiment, the opening on the avoidance part is U-shaped.

[0034] In this embodiment, the first suction cup 23 is placed in the U-shaped portion. When the first and second suction cups open and close the soft bag, the U-shaped portion can avoid interference with the soft bag.

[0035] In this embodiment, the first suction cup is positioned in the middle of the U-shaped portion.

[0036] In this embodiment, the bag hanging pin 11 is placed on top of the carrier 1 and faces the first suction cup 23. The bag hanging pin hangs the bag from both sides of the soft bag fixing part, and the direction of the bag hanging pin is towards the first suction cup. The bag protection part and the first suction cup are on the same side of the mounting part, which can effectively protect the soft bag on the bag hanging pin.

[0037] In this embodiment, the first suction cup 23 is connected to the mounting member 22, the mounting member 22 is connected to the first drive 21, and the protective bag member 4 is placed on the same side of the mounting member 22 as the first suction cup 23. The first drive moves the mounting member closer to or away from the soft bag, thereby causing the first suction cup and the protective bag member on the mounting member to move synchronously. Only one first drive is needed to achieve simultaneous movement of the first suction cup and the protective bag member, reducing costs. Moreover, the design of this utility model has a small overall space and multiple components have relative movement, which can effectively reduce space and avoid interference.

[0038] In this embodiment, the second suction cup 33 is connected to the second mounting bracket 32, and the second mounting bracket 32 ​​is connected to the second drive 31. The second drive moves the second mounting bracket closer to or away from the soft bag, causing the second suction cup on the second mounting member to move closer to or away from the soft bag simultaneously.

[0039] In this embodiment, the mounting component and the second mounting bracket are respectively placed on the front and rear sides of the soft bag and parallel to the plane of the soft bag. The first suction cup and the second suction cup are respectively vertically mounted on the mounting component and the second mounting bracket, and the suction end of the suction cup faces the soft bag.

[0040] In this embodiment, both the first suction cup and the second suction cup are connected to a negative pressure device.

[0041] In this embodiment, the first drive is placed on one side of the mounting component and its output end is perpendicular to the mounting component, while the second drive is placed on one side of the second mounting frame and its output end is perpendicular to the second mounting frame. This makes reasonable use of space and does not affect the conveying of the soft bag.

[0042] The working principle of this utility model is as follows: The carrier includes a bag hanging frame, and a bag hanging pin is set on the bag hanging frame. The bag hanging frame is movable. The soft bag is stretched into place on the bag hanging pin by the bag hanging frame. When the first suction cup and the second suction cup open the soft bag from the front and back respectively, the soft bag will drive the bag hanging frame to move closer to each other. When the soft bag is closed, the soft bag unfolds to both sides, and the bag hanging frame returns to its position at the same time. During this process, the soft bag and the bag hanging frame will have relative displacement, which makes it easy for the soft bag to fall off. In this utility model, the first suction cup is located on the side of the carrier where the bag hanging pin is located. On the same side as the first suction cup, a bag protection component is provided. When the first suction cup approaches or moves away from the soft bag, the bag protection component moves synchronously with the first suction cup to limit the soft bag on the bag hanging pin and prevent the soft bag from falling off. The bag protection component and the first suction cup share a drive, which reduces costs, makes full use of space and avoids interference, and ensures the smooth filling of soft bags.

[0043] Example 2:

[0044] like Figure 1-4The illustrated powder-liquid dual-chamber bag filling machine includes a conveyor line equipped with the soft bag opening and filling system described in Embodiment 1. A carrier 1 is placed on the conveyor line. Soft bags are placed on the carrier, which can move along the conveyor line. When the carrier reaches the filling station, the soft bag is opened and filled using the soft bag opening and filling system. The filled soft bag is then conveyed to the next station via the conveyor line, completing the powder-liquid dual-chamber bag filling process.

[0045] In this embodiment, the conveyor line is provided with a bag loading station 100, a packaging material purification station 101, a cutting station 102, a first weighing station 103, a first material dispensing station 104, a second weighing station 105, a second material dispensing station 106, a nitrogen filling station 107, a sealing station 108, a third weighing station 109, a material unloading station 110, and a bag exiting station 111. The first material dispensing station 104 and the second material dispensing station 106 are equipped with the soft bag opening and filling system.

[0046] The soft bags sequentially enter the carrier on the conveyor line through the bag-loading station, undergo purification treatment of the carrier and soft bags at the packaging material purification station, have a filling port cut at the cutting station, are weighed at the first weighing station, are filled with the first material through the filling port at the first material dispensing station, have the amount of the first material weighed at the first material weighing station, have the second material filled with the second material through the filling port at the second material dispensing station, are filled with nitrogen at the nitrogen filling station, have the filling port sealed at the sealing station, have the amount of the second material weighed at the second material weighing station, are unloaded from the carrier on the conveyor line at the unloading station, and are transported to the next process at the bag exit station. The bag-opening and filling actions at the first and second material dispensing stations are completed by a soft bag opening and filling system according to this utility model.

[0047] In this embodiment, the first material and the second material are two different powders, and the content of the first material in the soft bag is less than that of the second material. Since the content of the first material is less, it is filled first to avoid the problem of powder scattering when the second material is filled and the bag is opened later.

[0048] In this embodiment, the first material dispensing station uses a tube to dispense the first material into the soft bag. The tube dispensing has high precision and is suitable for materials like the first material that require small-volume filling. The second material dispensing station uses a screw to dispense the material, which is suitable for materials like the second material that require large-volume filling.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
