Description

Technical Field

[0001] The utility model generally relates to the technical field of medical equipment, and in particular to a transfer device and a liquid dispensing system with a marking function. Background Art

[0002] Infusion is a commonly used medical method in clinical practice. Through this medical method, liquid substances such as liquid medicine and nutrient solution can be infused into the patient's body to help the patient recover. When a patient needs to receive an infusion, medical staff often need to mix a variety of different infusion drugs according to the condition to prepare a therapeutic liquid with better efficacy. In clinical practice, medical staff can transfer drugs from different containers such as ampoules or vials into an infusion bag for mixing to obtain the therapeutic liquid required by the patient.

[0003] In order to solve the problem that it is difficult to meet the large amount of liquid preparation needs due to the shortage of medical staff, an automated liquid preparation system is usually used to assist medical staff in the preparation of liquid medicine. In the liquid preparation system, the prepared infusion bags generally include qualified infusion bags and unqualified infusion bags. Among them, the reason for the unqualified infusion bags is generally due to an error in a certain link in the automated liquid preparation (for example, the medicine in the designated medicine bottle is not injected into the infusion bag according to the prescription). If the liquid preparation system unloads the prepared infusion bags at the same unloading position, the qualified infusion bags and the unqualified infusion bags will be mixed together, and it is difficult for medical staff to distinguish between qualified infusion bags and unqualified infusion bags. In the prior art, two unloading positions are usually set for the liquid preparation system to unload qualified infusion bags and unqualified infusion bags separately. For example, the liquid preparation system is allowed to unload qualified infusion bags at the first unloading position and unload unqualified infusion bags at the second unloading position.

[0004] However, two sets of unloading devices (also called transfer devices) are required to unload the prepared infusion bags twice, thereby increasing the manufacturing cost. In addition, since the infusion bags need to be unloaded at two unloading positions respectively, the links of the automation process are increased, which is not conducive to improving the efficiency of unloading the infusion bags. Summary of the invention

[0005] The utility model is proposed in view of the above situation, and aims to provide a transfer device and a liquid dispensing system with a marking function, which can reduce manufacturing costs and improve the efficiency of unloading infusion bags.

[0006] To this end, the utility model provides a first aspect of a transfer device with a marking function, which is applied to a liquid dispensing system including a carrier for mounting a liquid bag, the liquid bag including a neck and a containing portion, the transfer device including a carrying mechanism, a hooking mechanism fixed to a first fixed position of the carrying mechanism, a marking mechanism fixed to a second fixed position of the carrying mechanism, and a driving mechanism; the carrying mechanism is configured to be movable relative to the carrier; the hooking mechanism is configured to unload the liquid bag from the carrier and includes a main arm and a driven arm, one end of the main arm is fixedly connected to the carrying mechanism, and the other end of the main arm is rotatably connected to the driven arm; the marking mechanism is configured to contact the liquid bag in a direction The method leaves a target mark on the liquid bag, and when the marking mechanism contacts the liquid bag, the liquid bag is at least partially located between the first fixed position and the second fixed position; the driving mechanism is configured to drive the carrying mechanism to move, and when the liquid bag is unloaded, the driving mechanism drives the carrying mechanism to make the driven arm of the hooking mechanism abut against the neck of the liquid bag, and the driving mechanism drives the carrying mechanism to move the driven arm away from the carrier to unload the liquid bag from the carrier; when the liquid bag is marked, the driving mechanism drives the carrying mechanism to move the marking mechanism toward the carrier to make the marking mechanism contact the liquid bag.

[0007] In the first aspect of the utility model, since the hooking mechanism and the marking mechanism are both fixed to the carrying mechanism, when the carrying mechanism moves, the hooking mechanism and the marking mechanism can be linked, so that the liquid bag can be easily marked during the process of unloading the liquid bag, thereby improving the efficiency of unloading the liquid bag. In addition, the marking of the liquid bag can facilitate the distinction between qualified liquid bags and unqualified liquid bags. In this case, a set of transfer devices can be used to unload the liquid bag at one unloading position while facilitating the distinction between qualified liquid bags and unqualified liquid bags, thereby reducing the links of the automated process and helping to improve the efficiency of unloading the liquid bag. In addition, compared with using two sets of transfer devices to unload the liquid bag at two unloading positions respectively, it can save manufacturing costs.

[0008] In addition, in the transfer device involved in the first aspect of the utility model, optionally, the driving mechanism is configured to drive the carrying mechanism to move to a first position and a second position respectively in a direction toward the carrier, and when the carrying mechanism moves from the second position to the first position, the hooking mechanism unloads the liquid bag from the carrier, and the marking mechanism contacts the liquid bag at the second position. In this case, the transfer device can mark and unload the liquid bag while simplifying the movement process of the carrying mechanism.

[0009] In addition, in the transfer device involved in the first aspect of the utility model, optionally, the driving mechanism is configured to drive the carrying mechanism to move to a third position, a fourth position and a fifth position respectively in the direction toward the carrier, wherein the fourth position is between the third position and the fifth position, and when the carrying mechanism moves from the fifth position to the third position or from the fourth position to the third position, the hooking mechanism unloads the liquid bag from the carrier, and at the fifth position the marking mechanism contacts the liquid bag. In this case, when the carrying mechanism is in the fourth position, it is convenient for the marking mechanism not to mark the liquid bag; when the carrying mechanism is in the fifth position, it is convenient for the marking mechanism to mark the liquid bag, so that the transfer device can mark and unload the liquid bag while simplifying the marking mechanism.

[0010] In addition, in the transfer device of the first aspect of the present invention, optionally, the angle formed by the main arm and the driven arm is an acute angle. In this case, when the hook mechanism unloads the liquid bag, the driven arm moves toward one side of the liquid bag at a height lower than the neck of the liquid bag, so that the driven arm can easily pass over the neck of the liquid bag and abut against the neck of the liquid bag from the other side of the liquid bag.

[0011] In addition, in the transfer device involved in the first aspect of the utility model, optionally, the hook mechanism includes an elastic element, and the driven arm forms the angle with the main arm through the elastic element. In this case, after the driven arm passes over the neck of the fluid bag, the driven arm can be restored to a preset angle with the main arm under the elastic recovery action of the elastic element, so that the driven arm can stably abut the neck of the fluid bag.

[0012] In addition, in the transfer device of the first aspect of the present invention, the liquid bag may have a plurality of necks, and the number of the driven arms corresponds to the number of the necks of the liquid bag, so that the driven arms can smoothly push the necks of the liquid bag to move so that the liquid bag is separated from the loading mechanism of the platform.

[0013] In addition, in the transfer device involved in the first aspect of the utility model, optionally, the hooking mechanism and the marking mechanism are arranged opposite to each other in the vertical direction, and when the marking mechanism contacts the fluid bag, the receiving portion is at least partially located between the first fixed position and the second fixed position. In this case, when the marking mechanism contacts the receiving portion of the fluid bag, it is easy to mark the receiving portion, and since the receiving portion has a larger surface area than the neck, the possibility of deviation of the marking position can be reduced.

[0014] In addition, in the transfer device involved in the first aspect of the utility model, optionally, the marking mechanism includes a stamp, a shell, and a frame sleeved between the stamp and the shell, and the frame is configured to protrude from the stamp and be elastically retractable relative to the stamp. In this case, since the liquid bag has the characteristics of being soft and easy to deform, the frame can be used to easily locate the position on the liquid bag that needs to be marked, so that the stamp can stably contact the surface of the liquid bag to leave a target mark on the liquid bag.

[0015] In addition, in the transfer device involved in the first aspect of the utility model, optionally, the carrier includes a plurality of loading mechanisms, the loading mechanisms include a first arm and a second arm arranged opposite to each other, the liquid bag is mounted on the loading mechanism in a manner that the neck is at least partially located between the first arm and the second arm, the transfer device is arranged opposite to the carrier, and the main arm is parallel to the first arm and the second arm and is located above the first arm and the second arm. In this case, when the first arm and the second arm are mounted with the liquid bag, it is easy to make the slave arm abut against the neck of the liquid bag, and the liquid bag can be easily separated from the first arm and the second arm by pushing the neck of the liquid bag by the slave arm.

[0016] In addition, the second aspect of the present invention further provides a liquid dispensing system, comprising a carrier and the transfer device involved in the first aspect of the present invention; the carrier is configured to mount a liquid bag and comprises a baffle, the baffle is arranged on the side of the liquid bag away from the transfer device; the transfer device is configured to unload the liquid bag from the carrier and mark the liquid bag. In this case, when the marking mechanism contacts the liquid bag to mark the liquid bag, the baffle is used to limit the liquid bag, which can improve the tightness of the contact between the marking mechanism and the surface of the liquid bag, thereby improving the clarity of the target mark.

[0017] According to the utility model, a transfer device and a liquid dispensing system with a marking function can be provided, which can reduce manufacturing costs and improve the efficiency of unloading liquid bags. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It should be noted that the terms "first", "second", "third" and "fourth" in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices. In the following description, the same symbols are given to the same components, and repeated descriptions are omitted. In addition, the drawings are only schematic diagrams, and the ratio of the sizes of the components to each other or the shapes of the components may be different from the actual ones.

[0034] The utility model relates to a transfer device with a marking function, which can be applied to a liquid dispensing system. Specifically, the transfer device can be applied to a liquid dispensing system to mark and unload liquid bags prepared by the liquid dispensing system. By marking the liquid bags, it is easy to distinguish qualified liquid bags from unqualified liquid bags; in addition, by unloading the liquid bags, it is easy to take the prepared liquid bags.

[0035] In the present invention, since marking the liquid bags can facilitate the distinction between qualified and unqualified liquid bags, a set of transfer devices can be used to unload the liquid bags at one unloading position while facilitating the distinction between qualified and unqualified liquid bags, thereby reducing the links of the automated process and facilitating the improvement of the efficiency of unloading the liquid bags. In addition, compared with using two sets of transfer devices to unload the liquid bags at two unloading positions respectively, the manufacturing cost can be saved.

[0036] Hereinafter, the transfer device involved in the utility model will be described in conjunction with the accompanying drawings.

[0037] Figure 1 Schematic diagram showing a liquid dispensing system 1 according to an example of the present invention. Figure 2 Schematic diagram showing a fluid bag 11 according to an example of the present invention. Figure 3 1 is a schematic diagram showing the entirety of the stage 10 according to the example of the present invention.

[0038] In some examples, the liquid dispensing system 1 can carry the syringe, the medicine bottle and the liquid bag 11 and transfer liquid between the medicine bottle and the liquid bag 11 through the syringe. In addition, the liquid bag 11 can also be called an infusion bag.

[0039] For some examples, see Figure 1 The liquid preparation system 1 may include a carrier 10 , and the carrier 10 may be used to mount a liquid bag 11 .

[0040] In some examples, the carrier 10 can rotate. When the carrier 10 is mounted with the liquid bag 11, the liquid bag 11 can be transported to different processing stations by rotating the carrier 10. For example, the carrier 10 can transport the liquid bag 11 to the liquid preparation station for liquid preparation to obtain the prepared liquid bag 11. For another example, after the liquid bag 11 is prepared, the carrier 10 can transport the liquid bag 11 to the unloading station to unload the liquid bag 11.

[0041] In some examples, the liquid preparation operation may include transferring the liquid medicine in the medicine bottle to the liquid bag 11 through a syringe for mixing.

[0042] In some examples, the liquid dispensing system 1 may include a transfer device 2. The transfer device 2 may be used to unload the fluid bag 11 from the carrier 10. In some examples, the transfer device 2 may be configured to unload the fluid bag 11 from the carrier 10 and mark the fluid bag 11.

[0043] For some examples, see Figure 1 The transfer device 2 can be arranged opposite to the carrier 10.

[0044] For some examples, see Figure 2 The fluid bag 11 may include a neck 112 and a receiving portion 114. In some examples, the receiving portion 114 may have a receiving chamber for receiving the drug solution. The neck 112 may have a hollow channel communicating with the receiving chamber.

[0045] For some examples, see Figure 2 The neck 112 of the fluid bag 11 may have a flange 1122, and the flange 1122 may be annular. In addition, the flange 1122 may be a protrusion extending outward from the outer wall of the neck 112.

[0046] In some examples, the carrier 10 can mount the fluid bag 11 via the supporting flange 1122 .

[0047] In some examples, the carrier 10 includes a plurality of carrier mechanisms 12 ( Figure 1 Two of the loading mechanisms 12 are schematically indicated, and the loading mechanisms 12 can be used to mount the fluid bag 11 .

[0048] For some examples, see Figure 3 , the loading mechanism 12 may include a first arm 122 and a second arm 124 disposed opposite to each other, and the fluid bag 11 may be mounted on the loading mechanism 12 in a manner that the neck 112 is at least partially located between the first arm 122 and the second arm 124. In other words, the first arm 122 and the second arm 124 may mount the fluid bag 11 by supporting the flange 1122 of the neck 112. In this case, the loading mechanism 12 may facilitate mounting the fluid bag 11 on the carrier 10, and may facilitate unloading the fluid bag 11 mounted on the carrier 10.

[0049] For some examples, see Figure 3 The loading mechanism 12 may include a first arm 122, a second arm 124, and a third arm 126 that are arranged opposite to each other. In addition, the fluid bag 11 may include two necks 112 (e.g., a first neck and a second neck), the first neck may be at least partially located between the first arm 122 and the second arm 124, and the second neck may be at least partially located between the second arm 124 and the third arm 126.

[0050] Figure 4 1 is a schematic diagram showing the entirety of a transfer device 2 according to an example of the present invention.

[0051] Figure 5 1 is a schematic diagram showing a first viewing angle of the transfer device 2 involved in the example of the present utility model.

[0052] Figure 6 1 is a schematic diagram showing a second viewing angle of the transfer device 2 involved in the example of the present utility model.

[0053] Figure 7 2 is a schematic diagram showing a marking mechanism 26 involved in an example of the present utility model. It should be noted that, for the convenience of description, Figure 6 and Figure 7 Some structures are omitted, which should not be understood as any limitation to the present invention.

[0054] As described above, the transfer device 2 of the present invention can mark and unload the liquid bag 11 mounted on the carrier 10 .

[0055] For some examples, see Figure 4 The transfer device 2 may include a carrying mechanism 22, a hooking mechanism 24, and a marking mechanism 26. The carrying mechanism 22 may be used to support the hooking mechanism 24 and the marking mechanism 26.

[0056] In some examples, the supporting mechanism 22 may be configured to be movable relative to the carrier 10 .

[0057] For some examples, see Figure 1 or Figure 4 The carrying mechanism 22 can be configured to be movable relative to the carrier 10 in the direction D1 toward the carrier 10. Thus, the hooking mechanism 24 and the marking mechanism 26 can be brought close to the carrier 10. In some examples, see Figure 1 or Figure 4 The carrying mechanism 22 can be configured to be movable relative to the carrier 10 in a direction D2 facing away from the carrier 10 . Thus, the hooking mechanism 24 and the marking mechanism 26 can be moved away from the carrier 10 .

[0058] For some examples, see Figure 4 The hook mechanism 24 and the marking mechanism 26 can be respectively fixed on the same side of the supporting mechanism 22. Thus, the hook mechanism 24 and the marking mechanism 26 can be linked by the movement of the supporting mechanism 22.

[0059] In some examples, the supporting mechanism 22 may be in the shape of a plate. In addition, the supporting mechanism 22 may also be referred to as a substrate, a bottom plate, or a mounting plate.

[0060] For some examples, see Figure 4 The transfer device 2 may include a driving mechanism 28. The driving mechanism 28 may be configured to drive the carrying mechanism 22 to move.

[0061] In some examples, the driving mechanism 28 may be an electric cylinder, which may include a motor and an output shaft. In some examples, the output shaft may be connected to the supporting mechanism 22, and the motor may drive the supporting mechanism 22 to move via the output shaft.

[0062] For some examples, see Figure 4 The transfer device 2 may include a support mechanism 27. The support mechanism 27 may be used to install the drive mechanism 28. Thus, the drive mechanism 28 may be supported and fixed.

[0063] In some examples, the hooking mechanism 24 can be used to unload the liquid bag 11 mounted on the carrier 10. In addition, the marking mechanism 26 can be used to mark the liquid bag 11 mounted on the carrier 10. In some examples, the liquid bag 11 can be marked first and then unloaded.

[0064] For some examples, see Figure 5 , the hooking mechanism 24 can be fixed to the first fixed position A1 of the carrying mechanism 22, and the marking mechanism 26 can be fixed to the second fixed position A2 of the carrying mechanism 22. In this case, since the hooking mechanism 24 and the marking mechanism 26 are both fixed to the carrying mechanism 22, when the carrying mechanism 22 moves, the hooking mechanism 24 and the marking mechanism 26 can be linked, so that the liquid bag 11 can be easily marked during the process of unloading the liquid bag 11.

[0065] For some examples, see Figure 5 The first fixed position A1 and the second fixed position A2 may be two different positions on the same side of the supporting mechanism 22 in the vertical direction D3. In addition, the first fixed position A1 and the second fixed position A2 may have a preset distance L therebetween.

[0066] In some examples, the hooking mechanism 24 and the marking mechanism 26 may be arranged opposite to each other in the vertical direction D3, and the receiving portion 114 of the fluid bag 11 may be at least partially located between the first fixed position A1 and the second fixed position A2. In this case, when the marking mechanism 26 contacts the receiving portion 114 of the fluid bag 11, it is convenient to mark the receiving portion 114, and since the receiving portion 114 has a larger surface area than the neck 112, the possibility of deviation of the marking position can be reduced.

[0067] In some examples, the hook mechanism 24 can be configured to unload the fluid bag 11 from the carrier 10. In some examples, see Figure 5 or Figure 6 The hooking mechanism 24 may include a main arm 242 and a driven arm 244 , one end of the main arm 242 may be fixedly connected to the supporting mechanism 22 , and the other end of the main arm 242 may be rotatably connected to the driven arm 244 .

[0068] For some examples, see Figure 3 and Figure 6 When the transfer device 2 is disposed opposite to the carrier 10, the main arm 242 may be parallel to the first arm 122 and the second arm 124, and the main arm 242 may be located above the first arm 122 and the second arm 124. In this case, when the first arm 122 and the second arm 124 carry the fluid bag 11, the slave arm 244 can be easily brought into contact with the neck 112 of the fluid bag 11, and the neck 112 of the fluid bag 11 is pushed by the slave arm 244 to facilitate the fluid bag 11 to be separated from the first arm 122 and the second arm 124.

[0069] In some examples, when the liquid bag 11 is unloaded, the driving mechanism 28 can drive the carrying mechanism 22 to make the driven arm 244 of the hooking mechanism 24 abut against the neck 112 of the liquid bag 11, and the driving mechanism 28 can drive the carrying mechanism 22 to make the driven arm 244 move in a direction away from the carrier 10 (that is, in the direction D2 away from the carrier 10) to unload the liquid bag 11 from the carrier 10.

[0070] For some examples, see Figure 6 , the main arm 242 and the driven arm 244 may form an angle α. In addition, the angle α may be an acute angle. In this case, when the hooking mechanism 24 unloads the fluid bag 11, the driven arm 244 moves toward one side of the fluid bag 11 at a height lower than the neck 112 of the fluid bag 11, so that the driven arm 244 can easily pass over the neck 112 of the fluid bag 11 and abut against the neck 112 of the fluid bag 11 from the other side of the fluid bag 11.

[0071] In some examples, the hooking mechanism 24 may include an elastic element, and the driven arm 244 may form an angle α with the main arm 242 through the elastic element. In this case, after the driven arm 244 passes over the neck 112 of the fluid bag 11, the driven arm 244 can be restored to have an angle α with the main arm 242 under the elastic recovery effect of the elastic element, so that the driven arm 244 can stably abut the neck 112 of the fluid bag 11. In some examples, the elastic element may be a torsion spring.

[0072] In some examples, the marking mechanism 26 may be configured to leave a target mark on the fluid bag 11 by contacting the fluid bag 11 .

[0073] In some examples, the target mark may include a first mark. The first mark may be used to characterize a qualified fluid bag 11. In some examples, the target mark may include a second mark. The second mark may be used to characterize an unqualified fluid bag 11. Thus, the target mark can facilitate the distinction between a qualified fluid bag 11 and an unqualified fluid bag 11.

[0074] In some examples, marking the fluid bag 11 may mean leaving a target mark on the fluid bag 11 .

[0075] For some examples, see Figure 7 The marking mechanism 26 may include a stamp 262, a housing 264, and a frame 266 sleeved between the stamp 262 and the housing 264. The frame 266 may be configured to protrude from the stamp 262 and be elastically retractable relative to the stamp 262. In this case, since the fluid bag 11 is soft and easily deformable, the frame 266 can be used to easily locate the position on the fluid bag 11 that needs to be marked, so that the stamp 262 can stably contact the surface of the fluid bag 11 to leave a clear target mark on the fluid bag 11.

[0076] However, the present invention is not limited thereto. In other examples, the marking mechanism 26 may have a labeling function. That is, the marking mechanism 26 may generate a label, and the content of the label may be set according to different signals. The marking mechanism 26 may attach the label to the fluid bag 11 in a manner of contacting the fluid bag 11. In this case, the content of the target label may be flexibly adjusted, so that the first label and the second label may be flexibly switched.

[0077] In some examples, marking the fluid bag 11 may mean attaching a label to the fluid bag 11 .

[0078] In some examples, when the marking mechanism 26 contacts the fluid bag 11, the frame 266 can be compressed by the fluid bag 11 to be flush with the stamp 262 so that the stamp 262 fully contacts the fluid bag 11, so that the stamp 262 can leave a target mark on the fluid bag 11. In some examples, the stamp 262 can be a self-inking stamp or a penetration stamp.

[0079] In some examples, when marking the fluid bag 11 , the driving mechanism 28 may drive the carrying mechanism 22 to move the marking mechanism 26 toward a direction close to the carrier 10 so that the marking mechanism 26 contacts the fluid bag 11 .

[0080] In some examples, when the marking mechanism 26 contacts the fluid bag 11 , the fluid bag 11 may be at least partially located between the first fixed position A1 and the second fixed position A2 , thereby facilitating leaving a target mark on the body of the fluid bag 11 (eg, the containing portion 114 ).

[0081] Figure 8 1 is a schematic diagram showing a first embodiment of the marking and unloading fluid bag 11 according to an example of the present invention. Fig. 9 1 is a schematic diagram showing a second embodiment of the marking and unloading fluid bag 11 according to the example of the present invention.

[0082] In some examples, the liquid preparation system 1 can automatically determine whether the prepared liquid bag 11 is a qualified liquid bag 11 or an unqualified liquid bag 11. For example, the liquid preparation system 1 can determine whether the prepared liquid bag 11 is qualified based on an error signal generated in the liquid preparation process.

[0083] In some examples, the liquid dispensing system 1 may send a first signal based on a qualified liquid bag 11 and send a second signal based on an unqualified liquid bag 11. That is, the first signal may correspond to a qualified liquid bag 11 and the second signal may correspond to an unqualified liquid bag 11.

[0084] For some examples, see Figure 8 The driving mechanism 28 can be configured to drive the carrying mechanism 22 to move to the first position P1 and the second position P2 in the direction D1 toward the carrier 10, respectively. Figure 8 The driving mechanism 28 can also be configured to drive the supporting mechanism 22 to move to the second position P2 and the first position P1 in the direction D2 facing away from the carrier 10 .

[0085] For some examples, see Figure 8 When the carrying mechanism 22 is at the second position P2 , the neck 112 of the fluid bag 11 may be located between the driven arm 244 and the carrying mechanism 22 .

[0086] For some examples, see Figure 8 When the carrying mechanism 22 is at the second position P2, the marking mechanism 26 can contact the fluid bag 11. That is, when the carrying mechanism 22 is at the second position P2, the marking mechanism 26 can mark the fluid bag 11. In this case, by marking the fluid bag 11 differently, it is easy to distinguish between qualified fluid bags 11 and unqualified fluid bags 11.

[0087] In some examples, when the carrying mechanism 22 is at the second position P2, the marking mechanism 26 may leave a first mark on the fluid bag 11 based on the first signal; in addition, the marking mechanism 26 may leave a second mark on the fluid bag 11 based on the second signal. In this case, the first mark and the second mark can facilitate the distinction between qualified fluid bags 11 and unqualified fluid bags 11.

[0088] In some examples, when the carrying mechanism 22 moves from the second position P2 to the first position P1, the hooking mechanism 24 can unload the liquid bag 11 from the carrier 10. Figure 8 , the driving mechanism 28 can drive the carrying mechanism 22 to move from the second position P2 to the first position P1. During the process of the carrying mechanism 22 moving from the second position P2 to the first position P1, the driven arm 244 of the hooking mechanism 24 can push the neck 112 of the liquid bag 11 to move so that the liquid bag 11 is separated from the carrying mechanism 12 of the carrier 10, thereby unloading the liquid bag 11 from the carrier 10. In this case, the transfer device 2 can mark and unload the liquid bag 11 while simplifying the moving process of the carrying mechanism 22.

[0089] In some examples, the fluid bag 11 may have a plurality of necks 112, and the number of the driven arms 244 may correspond to the number of the necks 112 of the fluid bag 11. Thus, the driven arms 244 can smoothly push the necks 112 of the fluid bag 11 to move so that the fluid bag 11 is separated from the loading mechanism 12 of the carrier 10. In some examples, the fluid bag 11 may have two necks 112 (see Figure 2 ), accordingly, the number of the driven arms 244 may be two (see Figure 5 ).

[0090] For some examples, see Fig. 9 The driving mechanism 28 may be configured to drive the supporting mechanism 22 to move to a third position P3, a fourth position P4 and a fifth position P5 in a direction D1 toward the carrier 10, respectively, wherein the fourth position P4 may be located between the third position P3 and the fifth position P5.

[0091] Also, see Fig. 9 The driving mechanism 28 can also be configured to drive the supporting mechanism 22 to move to the fifth position P5, the fourth position P4 and the third position P3 in the direction D2 facing away from the carrier 10, respectively.

[0092] In some examples, the driving mechanism 28 may be triggered by the first signal to drive the carrying mechanism 22 to move to the fourth position P4. Fig. 9 When the carrying mechanism 22 is at the fourth position P4, the neck 112 of the fluid bag 11 is located between the driven arm 244 and the carrying mechanism 22 .

[0093] In some examples, when the carrying mechanism 22 is at the fourth position P4, the marking mechanism 26 may not contact the fluid bag 11. In this case, when the carrying mechanism 22 is at the fourth position P4, the marking mechanism 26 does not mark the fluid bag 11, that is, does not mark the qualified fluid bag 11.

[0094] In some examples, when the carrying mechanism 22 moves from the fourth position P4 to the third position P3, the hooking mechanism 24 can unload the liquid bag 11 from the carrier 10. Fig. 9 The driving mechanism 28 can be triggered by the first signal to drive the carrying mechanism 22 to move from the fourth position P4 to the third position P3. During the process of the carrying mechanism 22 moving from the fourth position P4 to the third position P3, the driven arm 244 of the hooking mechanism 24 can push the neck 112 of the liquid bag 11 to move so that the liquid bag 11 is separated from the carrying mechanism 12 of the carrier 10, thereby unloading the liquid bag 11 from the carrier 10.

[0095] In some examples, the driving mechanism 28 may be triggered by the second signal to drive the carrying mechanism 22 to move to the fifth position P5. Fig. 9 , when the carrying mechanism 22 is at the fifth position P5, the neck 112 of the fluid bag 11 is located between the driven arm 244 and the carrying mechanism 22, and the marking mechanism 26 can contact the fluid bag 11. That is, when the carrying mechanism 22 is at the fifth position P5, the marking mechanism 26 can mark the fluid bag 11. In this case, by marking the unqualified fluid bag 11 based on the second signal and not marking the qualified fluid bag 11 based on the first signal, it is possible to easily distinguish between the qualified fluid bag 11 and the unqualified fluid bag 11.

[0096] In some examples, when the carrying mechanism 22 moves from the fifth position P5 to the third position P3, the hooking mechanism 24 can unload the liquid bag 11 from the carrier 10. Fig. 9 , the driving mechanism 28 can be triggered by the second signal to drive the carrying mechanism 22 to move from the fifth position P5 to the third position P3. In the process of the carrying mechanism 22 moving from the fifth position P5 to the third position P3, the driven arm 244 of the hooking mechanism 24 can push the neck 112 of the liquid bag 11 to move so that the liquid bag 11 is separated from the carrying mechanism 12 of the carrier 10, thereby unloading the liquid bag 11 from the carrier 10. In this case, when the carrying mechanism 22 is at the fourth position P4, it is convenient for the marking mechanism 26 not to mark the liquid bag 11; when the carrying mechanism 22 is at the fifth position P5, it is convenient for the marking mechanism 26 to mark the liquid bag 11, so that the transfer device 2 can mark and unload the liquid bag 11 while simplifying the marking mechanism 26.

[0097] In some examples, the third position P3 and the first position P1 may represent the same position. In some examples, the third position P3 and the first position P1 may represent the reset position of the driving mechanism 28 .

[0098] As described above, the carrier 10 may be configured to mount the fluid bag 11. In some examples, the carrier 10 may include a baffle, which may be disposed on a side of the fluid bag 11 away from the transfer device 2. In this case, when the marking mechanism 26 contacts the fluid bag 11 to mark the fluid bag 11, the baffle limits the position of the fluid bag 11, which can improve the tightness of the contact between the marking mechanism 26 and the surface of the fluid bag 11, thereby improving the clarity of the target mark.

[0099] According to the utility model, a transfer device 2 and a liquid dispensing system 1 with a marking function can be provided, which can reduce manufacturing costs and improve the efficiency of unloading a liquid bag 11 .

[0100] Although the utility model is specifically described above in conjunction with the accompanying drawings and examples, it is to be understood that the above description does not limit the utility model in any form. Those skilled in the art can modify and change the utility model as needed without departing from the essential spirit and scope of the utility model, and these modifications and changes all fall within the scope of the utility model.
