Description

Technical Field

[0001] This utility model relates to the field of soft bag technology, and in particular to a soft bag transfer device, a weighing device and a 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 transportation process and transported by a conveying mechanism. When the soft bag is transported to the weighing station, it needs to be transferred from the carrier on the conveying mechanism to the weighing mechanism for weighing. During the process of removing the soft bag from the pin on the carrier and transferring it, the soft bag is prone to falling off the bag removal mechanism, causing the soft bag to be unable to be transferred between the weighing mechanism and the conveying mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a soft bag transfer device, a weighing device, and a dispensing machine, which solves the problem of soft bags easily falling off during the transfer process in the prior art.

[0005] This utility model is implemented as follows: a soft bag transfer device includes a carrier and an opening and closing clamp for taking soft bags off and on the carrier. The carrier includes a bag hanging frame and bag hanging pins for cooperating with bag hanging holes on both sides of the soft bag. The opening and closing clamp includes a clamping plate for clamping the soft bag portion between the bag hanging pins, and the clamping plate extends to the bag hanging pins.

[0006] The soft bag is connected to the hanging pin on the carrier through hanging holes on both sides. The soft bag moves along the conveyor line via the carrier. When the soft bag passes the weighing station, it needs to be transferred from the carrier on the conveyor line to the weighing mechanism. The soft bag is picked up from the carrier by an opening and closing clamp and then moved horizontally to the weighing mechanism to complete the transfer. During this transfer, there is a risk that the soft bag will fall. To address this technical problem, the clamping plate of the opening and closing clamp in this invention extends to the hanging pin, so that the outer periphery of the hanging hole of the soft bag placed on the hanging pin is clamped by the clamping plate of the opening and closing clamp, reducing the risk of the soft bag falling.

[0007] A further technical solution of this utility model is: the end of the bag hanger is provided with an extension portion extending from both sides of the soft bag toward the middle, the bag hanging pin is provided on the extension portion, and the clamping plate is provided with a clearance opening extending from the middle of the soft bag toward both sides, the clearance opening being used to avoid the extension portion. The clearance opening on the opening and closing clamp effectively avoids interference between the opening and closing clamp and the carrier during the transfer of the soft bag, ensuring smooth transfer of the soft bag.

[0008] A further technical solution of this utility model is: the bag hanger and the extension form a U-shaped structure with their openings facing each other. There are two bag hangers on one carrier, each with a bag hanging pin. The bag hangers and the extension on the carrier form two U-shaped structures with their openings facing each other, resulting in high stability and preventing interference with the opening and closing clamps.

[0009] A further technical solution of this utility model is that the width of the clearance opening is greater than the width of the extension, and the opening and closing clamp can pass through the extension through the clearance opening. Because the width of the clearance opening is greater than the width of the extension, the opening and closing clamp can smoothly pass through the carrier when moving horizontally, ensuring the smooth transfer of the soft bag.

[0010] A further technical solution of this utility model is: the clearance opening is located at both ends of the clamping plate and is U-shaped with the opening facing outwards. The opening and closing clamp can avoid the bag hanging pin and the extension through the clearance opening, and the opening and closing clamp can have a larger contact area with the soft bag, increasing the stability of the soft bag being clamped by the opening and closing clamp.

[0011] A further technical solution of this utility model is: the bag-hanging pin has a semi-circular structure with the arc-shaped part of the semi-circle facing both sides of the soft bag. During the transfer and docking of the soft bag, the hanging hole on the soft bag is not necessarily circular and may be deformed to some extent. Furthermore, the bag-hanging pin stretches the soft bag to both sides. To ensure that the soft bag returns to the bag-hanging pin on the carrier after weighing, the bag-hanging pin in this utility model has a semi-circular structure with the arc-shaped part facing both sides of the soft bag, providing sufficient space for the hanging hole to ensure smooth bag hanging and that the soft bag is properly hooked.

[0012] This utility model also provides a soft bag weighing device, including a conveyor line, a weighing mechanism, and the aforementioned transfer device. The conveyor line is used for moving a carrier, and the opening and closing clamp is connected to a drive mechanism to transfer the soft bag on the carrier to the weighing mechanism.

[0013] The soft bag is connected to the hanging pin on the carrier through the hanging holes on both sides. The soft bag moves along the conveyor line via the carrier. When the soft bag passes the weighing station, it needs to be transferred from the carrier on the conveyor line to the weighing mechanism. The soft bag is picked up from the carrier by the opening and closing clamp and then moved horizontally to the weighing mechanism to complete the transfer. The design of the opening and closing clamp in this utility model can ensure the stability of the soft bag during the transfer process and during the loading and unloading of the soft bag.

[0014] A further technical solution of this utility model is: the weighing mechanism is provided with a weighing bag hanging frame and a weighing bag hanging pin for cooperating with the bag hanging holes on both sides of the soft bag. The end of the weighing bag hanging frame is provided with a weighing extension extending from both sides of the soft bag toward the middle. The weighing bag hanging pin is provided on the weighing extension. The opening and closing clamp can pass through the weighing extension.

[0015] After the soft bag transfer device removes the soft bag from the carrier, it hangs the soft bag on the weighing bag hanging pin of the weighing mechanism through the opening and closing clamp. When the opening and closing clamp hangs the soft bag on the weighing bag hanging pin, one side of the opening and closing clamp needs to pass through the weighing bag hanging pin on the weighing mechanism. In this utility model, the end of the weighing bag hanging frame of the weighing mechanism forms an extension, and the bag hanging pin is set on the extension. When the opening and closing clamp moves, it can pass through the extension and the weighing bag hanging pin at the same time, thereby avoiding interference between the weighing mechanism and the opening and closing clamp.

[0016] A further technical solution of this utility model is: the top of the weighing bag hanging pin is arc-shaped and the two sides are parallel planes. When hanging the bag, the hanging hole on the soft bag is deformed, and the structure of the weighing bag hanging pin can ensure that the soft bag is smoothly hung; at the same time, the top of the weighing bag hanging pin is arc-shaped, and when the soft bag is on the weighing mechanism, the force is mainly borne by the top of the weighing bag hanging pin. The arc-shaped top of the weighing bag hanging pin can better fit the hanging hole of the soft bag while avoiding deformation.

[0017] This utility model also provides a powder-liquid dual-chamber bag dispensing machine, including a conveyor line, a soft bag weighing device on the conveyor line, and a carrier placed on the conveyor line. The soft bag is placed on the carrier, which can move along the conveyor line. When the carrier reaches the weighing station, a soft bag transfer device transfers the soft bag from the carrier on the conveyor line to the weighing mechanism at the weighing station. After the process is completed, the soft bag is returned to the carrier on the conveyor line. The soft bag is then conveyed to the subsequent station via the conveyor line to complete the powder-liquid dual-chamber bag dispensing.

[0018] The beneficial effects of this utility model are as follows: The soft bag is connected to the hanging pin on the carrier through the hanging holes on both sides. The soft bag moves along the conveyor line through the carrier. When the soft bag passes the weighing station, it needs to be transferred from the carrier on the conveyor line to the weighing mechanism. The soft bag is picked up from the carrier by the opening and closing clamp and then moved horizontally to the weighing mechanism to complete the transfer. During this transfer process, there is a risk that the soft bag will fall. To address this technical problem, the clamping plate in this utility model is used to clamp the part of the soft bag between the hanging pins. At the same time, the clamping plate part of the opening and closing clamp extends to the hanging pin, so that the outer periphery of the hanging hole of the soft bag placed on the hanging pin is clamped by the clamping plate of the opening and closing clamp, reducing the risk of the soft bag falling.

[0031] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0032] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention.

[0033] Example 1:

[0034] Figure 1-6 A soft bag transfer device is shown, including a carrier 1 and an opening and closing clamp 2 for taking soft bags 6 off and on the carrier 1. The carrier 1 includes a bag hanger 11 and bag hanging pins 12 for engaging with bag hanging holes on both sides of the soft bag 6. The opening and closing clamp 2 includes a clamping plate 20 for clamping the portion of the soft bag 6 between the bag hanging pins 12, and the clamping plate 20 extends to the bag hanging pins 12.

[0035] The soft bag is connected to the hanging pins on the carrier through hanging holes on both sides. The soft bag moves along the conveyor line via the carrier. When the soft bag passes the weighing station, it needs to be transferred from the carrier on the conveyor line to the weighing mechanism. The soft bag is picked up from the carrier by an opening and closing clamp and then moved horizontally to the weighing mechanism to complete the transfer. During this transfer, there is a risk that the soft bag will fall. To address this technical problem, the clamping plate in this utility model is used to clamp the part of the soft bag between the hanging pins. At the same time, the clamping plate part of the opening and closing clamp extends to the hanging pin, so that the outer periphery of the hanging hole of the soft bag placed on the hanging pin is clamped by the clamping plate of the opening and closing clamp, reducing the risk of the soft bag falling.

[0036] In this embodiment, the hanging holes on both sides of the soft bag are located on the top sides of the soft bag. There are two hanging frames on the carrier, and each hanging frame is provided with a hanging pin. The hanging pin can pass through the hanging holes to support the soft bag.

[0037] In this embodiment, the opening and closing clamp also includes an opening and closing drive for driving the clamping plate 20 to open and close.

[0038] In this embodiment, the end of the bag hanger 11 is provided with an extension 13 extending from both sides of the soft bag 6 toward the middle. The bag hanging pin 12 is provided on the extension 13. The clamping plate 20 is provided with a clearance opening 21 opening from the middle of the soft bag 6 toward both sides. The clearance opening 21 is used to avoid the extension 13. The opening and closing clamp is provided with a clearance opening, which can effectively avoid interference between the opening and closing clamp and the carrier during the transfer of the soft bag, ensuring the smooth transfer of the soft bag.

[0039] In this embodiment, the bag hanger 11 and the extension 13 form a U-shaped structure with their openings facing each other. A carrier has two bag hangers, each equipped with a bag hanging pin. The bag hangers and the extension on the carrier form two U-shaped structures with their openings facing each other, resulting in high stability and preventing interference with the opening and closing clamps.

[0040] In this embodiment, the width of the clearance opening 21 is greater than the width of the extension 13, allowing the opening and closing clamp 2 to pass through the extension 13 via the clearance opening 21. The wider clearance opening allows the clamp to smoothly pass through the carrier during horizontal movement, ensuring the smooth transfer of the soft bag.

[0041] In this embodiment, the clearance openings 21 are located at both ends of the clamping plate 20 and are U-shaped with the openings facing outwards. The opening and closing clamps can avoid the bag hanging pins and extensions through the clearance openings, and the opening and closing clamps can have a larger contact area with the soft bag, increasing the stability of the soft bag being clamped by the opening and closing clamps.

[0042] In this embodiment, the bag-hanging pin 12 has a semi-circular structure with the arc-shaped portion of the semi-circle facing both sides of the soft bag. During transport and docking, the bag-hanging holes on the soft bag are not necessarily circular and may be deformed. Furthermore, the bag-hanging pin stretches the soft bag to both sides. To ensure that the soft bag returns to the bag-hanging pin on the carrier after weighing, the bag-hanging pin in this invention has a semi-circular structure with the arc-shaped portion facing both sides of the soft bag, providing sufficient space for the bag-hanging holes to ensure smooth bag hanging and that the soft bag is properly hooked.

[0043] Example 2:

[0044] like Figure 1-6 A soft bag weighing device is shown, including a conveyor line, a weighing mechanism 3, and the aforementioned transfer device. The conveyor line is used for moving a carrier 1, and the opening and closing clamp 2 is connected to a drive mechanism 4 to transfer the soft bag 6 on the carrier 1 to the weighing mechanism 3.

[0045] The soft bag is connected to the hanging pin on the carrier through the hanging holes on both sides. The soft bag moves along the conveyor line via the carrier. When the soft bag passes the weighing station, it needs to be transferred from the carrier on the conveyor line to the weighing mechanism. The soft bag is picked up from the carrier by the opening and closing clamp and then moved horizontally to the weighing mechanism to complete the transfer. The design of the opening and closing clamp in this utility model can ensure the stability of the soft bag during the transfer process and during the loading and unloading of the soft bag.

[0046] In this embodiment, the weighing mechanism and the conveyor line are located on opposite sides of the opening and closing clamp. The opening and closing clamp moves between the weighing mechanism and the conveyor line via a drive mechanism, thereby completing the transfer of the soft bag.

[0047] In this embodiment, the weighing mechanism 3 is provided with a weighing bag hanger 31 and a weighing bag hanger pin 32 for cooperating with the bag hanging holes on both sides of the soft bag 6. The end of the weighing bag hanger 31 is provided with a weighing extension 33 extending from both sides of the soft bag 6 toward the middle. The weighing bag hanger pin 32 is provided on the weighing extension 33. The opening and closing clamp 2 can pass through the weighing extension 33.

[0048] After the soft bag transfer device removes the soft bag from the carrier, it hangs the soft bag on the weighing bag hanging pin of the weighing mechanism through the opening and closing clamp. When the opening and closing clamp hangs the soft bag on the weighing bag hanging pin, one side of the opening and closing clamp needs to pass through the weighing bag hanging pin on the weighing mechanism. In this utility model, the end of the weighing bag hanging frame of the weighing mechanism forms an extension, and the bag hanging pin is set on the extension. When the opening and closing clamp moves, it can pass through the extension and the weighing bag hanging pin at the same time, thereby avoiding interference between the weighing mechanism and the opening and closing clamp.

[0049] In this embodiment, the top of the weighing bag hanging pin 32 is arc-shaped and the two sides are parallel planes. When hanging the bag, the hanging hole on the soft bag is deformed, and the structure of the weighing bag hanging pin can ensure that the soft bag is smoothly hung; at the same time, the top of the weighing bag hanging pin is arc-shaped, and when the soft bag is on the weighing mechanism, the force is mainly borne by the top of the weighing bag hanging pin. The arc-shaped top of the weighing bag hanging pin can better fit the hanging hole of the soft bag while avoiding deformation.

[0050] In this embodiment, a pushing mechanism 5 for pushing the soft bag opening is provided below the opening and closing clamp 2. This further ensures the stability of the soft bag transfer.

[0051] Example 3:

[0052] like Figure 1-7 The powder and liquid dual-chamber bag dispensing machine shown includes a conveyor line, on which the soft bag opening and filling system described in Embodiment 2 is provided, and the carrier 1 is placed on the conveyor line.

[0053] In this embodiment, the conveyor line is sequentially 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 weighing station, the second weighing station, and the third weighing station are equipped with the soft bag weighing device of Embodiment 2.

[0054] The soft bags sequentially pass through the bag-loading station onto the carrier on the conveyor line, 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 for protection, 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 first, second, and third weighing stations are equipped with the soft bag weighing device of Embodiment 2.

[0055] 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.

[0056] 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.

[0057] 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.
