Description

[0001] This application is a divisional application of the patent application with application number CN202110470385.8, titled Cap removing device for bag type container, and filed on April 28, 2021. TECHNICAL FIELD

[0002] The present disclosure relates to a cap removing method for a bag type container. BACKGROUND

[0003] Transfusion is a common medical method in clinic, by which liquid substances such as medicinal liquid and nutrient liquid can be transfused into a patient's body to help the patient recover. When a patient needs to receive transfusion, etc., different transfusion medicines are often mixed according to the patient's condition to prepare a treatment liquid with better curative effect. In clinic, medical staff, etc. can mix medicines in different containers such as ampoule bottles or syringes by transferring the medicines into a transfusion bag to obtain a treatment liquid required by the patient.

[0004] At present, medical staff, etc. usually use a manual operation method to prepare a treatment liquid required by a patient for transfusion. For example, when transferring medicines into a transfusion bag, the cap of the transfusion bag is removed by using a manual operation method to transfer the medicines into the transfusion bag.

[0005] However, since the medical staff in medical institutions are still in short supply at present, the manual operation method is difficult to efficiently prepare a treatment liquid when a large amount of transfusion is required. Therefore, it is necessary to provide a device capable of assisting medical staff in preparing a liquid, in particular, to provide a device capable of automatically removing the cap of a transfusion bag. SUMMARY

[0006] The present disclosure is proposed in view of the above-mentioned prior art, and aims to provide a cap removing device capable of automatically removing the cap of a bag type container.

[0007] To this end, the present disclosure provides a cap removing device for a bag type container, the bag type container comprising a main body portion for containing material and a cap provided on the main body portion, the cap removing device comprising a carrying mechanism, a separating mechanism and a driving mechanism for driving the separating mechanism, the carrying mechanism being configured to fix the main body portion in a manner that exposes the cap, the separating mechanism being configured to separate the cap of the bag type container from the main body portion, the separating mechanism comprising a first arm and a second arm arranged oppositely, when the bag type container is subjected to cap removal, the driving mechanism drives the separating mechanism to make the first arm and the second arm of the separating mechanism abut against the cap, and the driving mechanism drives the separating mechanism to make the first arm and the second arm move in a direction away from the main body portion to separate the cap from the main body portion.

[0008] In the cap removing device related to the present disclosure, the bag container to be capped is fixed by the carrying mechanism, the first arm and the second arm of the separating mechanism are abutted to the cap of the bag container by the driving mechanism, and the first arm and the second arm of the separating mechanism are driven to move away from the main body of the bag container, so as to separate the cap of the bag container from the main body. Thus, the cap of the bag container can be automatically removed.

[0009] In addition, in the cap removing device related to the present disclosure, optionally, the distance between the first arm and the second arm is less than the maximum width of the cap, and the first arm and the second arm are abutted to the cap from below the cap. In this case, by abutting to the cap from below the cap, the force away from the main body can be conveniently applied to the cap.

[0010] In addition, in the cap removing device related to the present disclosure, optionally, the carrying mechanism is configured to push the bag container to the front of the separating mechanism along the left-right direction, the driving mechanism is configured to drive the first arm and the second arm to move to below the cap along the front-back direction, and the driving mechanism is configured to drive the first arm and the second arm to rotate around the axis along the left-right direction to separate the cap from the main body. In this case, by driving the first arm and the second arm to rotate around the axis along the left-right direction, the first arm and the second arm can be provided with the force towards the upper direction to separate the cap from the main body.

[0011] In addition, in the cap removing device related to the present disclosure, optionally, the driving mechanism includes a transmission shaft in a long strip shape, the transmission shaft has a first end connected with the separating mechanism and a second end opposite to the first end, the carrying mechanism includes a first supporting part and a second supporting part for fixing the bag container, and the carrying mechanism is configured to be rotatable to make the first supporting part located in front of the first end and the second supporting part located in front of the second end, the transmission shaft is moved along the front-back direction to make the first end drive the separating mechanism to remove the cap of the bag container carried on the first supporting part, and make the second end move the bag container carried on the second supporting part away from the second supporting part. In this case, by moving the transmission shaft along the front-back direction, the bag container carried on the first supporting part can be simultaneously capped and the bag container carried on the second supporting part can be moved away, so as to simplify the structure design.

In this case, the lever structure can be easily formed to remove the cap from the bag-type container by the first resistance arm and the first power arm coupled to each other and the second resistance arm and the second power arm coupled to each other.

[0013] Further, in the cap removing device according to the present disclosure, the driving mechanism can include a guide portion on a travel path of the first power arm and the second power arm, the driving mechanism can move the first resistance arm and the second resistance arm in the front-rear direction to below the cap, and when the first power arm and the second power arm reach the guide portion and the first resistance arm and the second resistance arm continue to travel in the front direction, the guide portion can guide the first power arm and the second power arm to have a travel component in the up-down direction, so that the first resistance arm and the second resistance arm have a travel component in the up-down direction. In this case, the driving mechanism can generate two-dimensional forces by providing the guide portion that can guide the first power arm and the second power arm on the travel path.

[0014] Further, in the cap removing device according to the present disclosure, the first resistance arm, the first shaft, and the first power arm of the first arm can be formed in an L-shaped structure, and the second resistance arm, the second shaft, and the second power arm of the second arm can be formed in an L-shaped structure, the first resistance arm and the second resistance arm can be substantially in the front-rear direction, and the first power arm and the second power arm can be substantially in the up-down direction when in an initial posture. In this case, the first arm and the second arm formed in the L-shaped structure can guide the first power arm and the second power arm when the first resistance arm and the second resistance arm travel in the front direction.

[0015] In addition, in the cap removing device according to the present disclosure, the separating mechanism can further include a restoring member configured to provide a restoring force toward the lower side of the first and second resistance arms or the front side of the first and second power arms. In this case, the first and second arms can be automatically restored to the initial state after the cap is removed, so as to facilitate the next cap removing operation.

[0016] In addition, in the cap removing device according to the present disclosure, a recycling mechanism can be further provided below the first and second arms, and the removed cap can slide to the recycling mechanism via the first and second arms inclined in the oblique up-down direction. In this case, the removed cap can be recycled by the first and second arms inclined in the oblique up-down direction and the recycling mechanism provided below the first and second arms.

[0017] In addition, in the cap removing device according to the present disclosure, the main body of the bag container can include a containing portion having a containing chamber and a neck portion having a hollow passage and communicating with the containing chamber for material flow, and the cap can be provided at the opening of the neck portion, and the carrying mechanism can fix the main body by clamping the neck portion in the up-down direction.

In the following description, for the same components, the same reference numerals are assigned and repetitive description is omitted. In addition, the drawings are merely schematic ones and the ratio of the size between the components or the shape of the components and the like can be different from the actual ones.

[0029] It should be noted that the terms "comprising" and "having" and any variations thereof, such as a process, a method, a system, a product, or an apparatus including or having a series of steps or units, are not necessarily limited to those clearly listed steps or units, but can include or have other steps or units that are not clearly listed or inherent to the process, the method, the product, or the apparatus.

[0030] In addition, the sub-headings and the like referred to in the following description of the present disclosure are not intended to limit the content or scope of the present disclosure, and merely serve as a reading aid. Such sub-headings should not be understood to divide the content of the article, nor should the content under the sub-headings be limited only to the scope of the sub-headings.

[0031] The present embodiment relates to a cap removing device for a bag container, which can be used to automatically remove the cap of the bag container during the process of handling the bag container or dispensing a liquid medicine. The cap removing device for a bag container can be simply referred to as a cap removing device, and can also be referred to as a cap pulling device, a cap removing device, a cap detaching device, an automatic cap separating device for a bag container, or a cap separating device, etc. The cap removing device according to the present embodiment can also be used in a bag container handling system or an automatic liquid dispensing system, so as to facilitate the automatic handling of the bag container or the automatic dispensing of the liquid medicine. Through the cap removing device according to the present embodiment, the cap of the bag container can be automatically removed.

[0032] Hereinafter, the cap removing device for a bag container according to the present embodiment will be described in detail with reference to the accompanying drawings.

[0033] Figure 1 is a schematic view showing the cap removing device 1 and the bag container 100 according to an example of the present embodiment. It should be noted that the relative position and direction terms such as "upper", "toward the upper", "lower", "toward the lower", "vertical direction", "left side", "toward the left side", "left", "toward the left", "right side", "toward the right side", "right", "toward the right", "horizontal direction", "front", "toward the front", "rear", "toward the rear", and "front-rear direction" are referred to the usual operation posture, and should not be considered as limiting.

[0034] In the present embodiment, the bag container 100 can include a main body portion 101 for containing a material and a cap 102 provided to the main body portion 101 (see Figure 1 ). In some examples, the material contained in the main body portion 101 can be a liquid material such as physiological saline, a glucose solution, a liquid medicine, blood, etc. In other examples, the material contained in the main body portion 101 can also be a powder material.

[0035] In some examples, the main body portion 101 of the bag container 100 can include a containing portion 103 having a containing chamber (not shown) and a neck portion 104 having a hollow passage (not shown) and communicating with the containing chamber for the flow of the material (see Figure 1 ). Figure 1

[0036] ​In the present embodiment, the hollow passage of the neck portion 104 can be filled with a soft, pierceable or easily pierceable object such as a rubber plug, and the cap 102 can be a hard, non-easily pierceable object such as a hard plastic cover plate. By the cap 102 being separated from the neck portion 104 by the cap removal device 1 involved in the present embodiment, it is possible to facilitate subsequent operations by medical staff or the like, such as piercing the rubber plug in the hollow passage using a needle tube to access the medical liquid contained in the accommodation chamber.

[0037] In some examples, the neck portion 104 can be cylindrical. In some examples, the neck portion 104 can include two or more cylindrical segments having different diameters. That is, in some examples, the neck portion 104 can be formed by layering two or more cylindrical segments having different diameters. In some examples, the cap 102 can be a circular disc. In some examples, the diameter at the connection between the neck portion 104 and the cap 102 can be smaller than the diameter of the cap 102. In some examples, the minimum width at the connection between the neck portion 104 and the cap 102 can be smaller than the maximum width of the cap 102.

[0038] In some examples, the bag container 100 can be an infusion bag.

[0039] In the present embodiment, the cap removal device 1 can include a carrying mechanism 10, a separating mechanism 20, and a driving mechanism 30 for driving the separating mechanism 20 (see Figure 1 ). The carrying mechanism 10 can be configured to fix the main body portion 101 in a manner that exposes the cap 102, and the separating mechanism 20 can be configured to separate the cap 102 of the bag container 100 from the main body portion 101. When the bag container 100 is capped, the driving mechanism 30 can drive the separating mechanism 20 to abut against the cap 102 of the bag container 100, and the driving mechanism 30 can drive the separating mechanism 20 to move in a direction away from the main body portion 101 to separate the cap 102 from the main body portion 101.

[0040] In the cap removal device 1 involved in the present embodiment, the bag container 100 to be capped is fixed by the carrying mechanism 10, the separating mechanism 20 is abutted against the cap 102 of the bag container 100 by the driving mechanism 30, and the separating mechanism 20 is driven to move away from the main body portion 101 of the bag container 100 to separate the cap 102 of the bag container 100 from the main body portion 101. Thus, the cap 102 of the bag container 100 can be removed automatically.

[0041] Figure 2 is a schematic view showing the support portion 11 of the carrying mechanism 10.

[0042] In some examples, the carrying mechanism 10 can include a support portion 11 in a U shape (see Figure 2) In some examples, the neck portion 104 of the bag container 100 can be held in the support portion 11 in a U shape. In some examples, the carrying mechanism 10 can fix the main body portion 101 by holding the neck portion 104 of the bag container 100. In some examples, the carrying mechanism 10 can fix the main body portion 101 by holding the neck portion 104 in the up-down direction. In Figure 1 In the illustrated embodiment, the cap 102 is oriented upward D1 with respect to the main body portion 101, and the main body portion 101 is oriented downward D2 with respect to the cap 102. In this case, by holding the neck portion 104 in the up-down direction, it is possible to facilitate fixing of the main body portion 101 using its own gravity more stably.

[0043] In various embodiments, the "up-down direction" can be understood as a direction in which the main body portion 101 of the bag container 100 is directed toward the cap 102 or a direction in which the cap 102 of the bag container 100 is directed toward the main body portion 101, the "upward direction" can be understood as a direction in which the main body portion 101 is directed toward the cap 102, and the "downward direction" can be understood as a direction in which the cap 102 is directed toward the main body portion 101. In Figure 1 In the illustrated embodiment, the "upward direction" can be understood as the direction indicated by D1, and the "downward direction" can be understood as the direction indicated by D2.

[0044] In various embodiments, the "front-rear direction" can be understood as a direction in which the separation mechanism 20 is directed toward the carrying mechanism 10 or a direction in which the carrying mechanism 10 is directed toward the separation mechanism 20, the "forward direction" can be understood as a direction in which the separation mechanism 20 is directed toward the carrying mechanism 10, and the "rearward direction" can be understood as a direction in which the carrying mechanism 10 is directed toward the separation mechanism 20. In Figure 1 In the illustrated embodiment, the "forward direction" can be understood as the direction indicated by D3, and the "rearward direction" can be understood as the direction indicated by D4.

[0045] In some examples, the support portion 11 can include first and second support plates 111 and 112 disposed opposite each other (see FIG. 2). In some examples, a first elastic portion 113 can be provided on the inner side of the first support plate 111, and a second elastic portion 114 can be provided on the inner side of the second support plate 112 (see FIG. 2). In some examples, the first and second elastic portions 113 and 114 can be disposed opposite each other in a direction that crosses the U-shaped structure. In this case, by the first and second elastic portions 113 and 114 generating an elastic force toward the inner side, it is possible to hold the neck portion 104 of the bag container 100 more stably. Figure 2 Figure 2 In some examples, the support portion 11 can include first and second support plates 111 and 112 disposed opposite each other (see FIG. 2). In some examples, a first elastic portion 113 can be provided on the inner side of the first support plate 111, and a second elastic portion 114 can be provided on the inner side of the second support plate 112 (see FIG. 2). In some examples, the first and second elastic portions 113 and 114 can be disposed opposite each other in a direction that crosses the U-shaped structure. In this case, by the first and second elastic portions 113 and 114 generating an elastic force toward the inner side, it is possible to hold the neck portion 104 of the bag container 100 more stably.

[0046] ​In some examples, the first support plate 111 and the second support plate 112 can be elastic plates. In this case, when the neck portion 104 is caught between the first support plate 111 and the second support plate 112, the neck portion 104 can be more stably caught by the elasticity of the first support plate 111 and the second support plate 112. In some examples, the first support plate 111 and the second support plate 112 can be flexible plates. Thereby, damage to the neck portion 104 can be reduced.

[0047] In some examples, the first support plate 111 and the second support plate 112 can be plate-shaped. In some examples, the first support plate 111 and the second support plate 112 can be flat sheet-shaped.

[0048] In some examples, the first support plate 111 and the second support plate 112 can be arranged side by side. In some examples, the first support plate 111 and the second support plate 112 can be arranged in parallel. In other examples, the first support plate 111 and the second support plate 112 can be gradually spaced apart from each other from the opening of the U-shaped structure to the closed portion of the U-shaped structure. That is, the U-shaped structure formed by the first support plate 111 and the second support plate 112 can be closed, and the first support plate 111 and the second support plate 112 can be close to each other at the opening of the U-shaped structure. Thereby, it can be helpful to stably catch the neck portion 104 of the bag-type container 100 in the U-shaped structure formed by the first support plate 111 and the second support plate 112.

[0049] In some examples, the first support plate 111 and the second support plate 112 can have a chamfered, for example, a rounded corner, design at the opening of the U-shaped structure. Thereby, it can be facilitated to push the neck portion 104 of the bag-type container 100 into the first support plate 111 and the second support plate 112 from the outside and catch it there.

[0050] In some examples, the first support plate 111 and the second support plate 112 can be gradually spaced apart from each other from the closed portion of the U-shaped structure to the first elastic portion 113 and the second elastic portion 114, and can be gradually spaced apart from each other from the first elastic portion 113 and the second elastic portion 114 to the opening of the U-shaped structure. In this case, the portion from the first elastic portion 113 and the second elastic portion 114 to the opening of the U-shaped structure can facilitate pushing the neck portion 104 into the first support plate 111 and the second support plate 112, and the portion from the first elastic portion 113 and the second elastic portion 114 to the closed portion of the U-shaped structure can facilitate catching the neck portion 104.

[0051] In other examples, the first support plate 111 and the second support plate 112 can be configured to be movable toward each other. For example, the first support plate 111 and the second support plate 112 can be configured to be driven toward each other. Thereby, the main body portion 101 can be fixed by clamping the neck portion 104.

[0052] Figure 3 A schematic view showing the cooperation of the carrying mechanism 10 with the separating mechanism 20 and the conveying device 800 is shown.

[0053] In some examples, the carrying mechanism 10 can include a plurality of support portions 11 (see Figure 3 ). In some examples, the number of support portions 11 of the carrying mechanism 10 can be 2, 4, or 8. For example, in the embodiment shown in Figure 3 , the support portions 11 can be a first support portion 11a, a second support portion 11b, a third support portion 11c, and a fourth support portion 11d.

[0054] In some examples, the carrying mechanism 10 can include a mounting table 12 for mounting the first support portion 11a, the second support portion 11b, the third support portion 11c, and the fourth support portion 11d. In some examples, the first support portion 11a, the second support portion 11b, the third support portion 11c, and the fourth support portion 11d can be evenly arranged on the mounting table 12 (see Figure 3 ).

[0055] In some examples, the plurality of support portions 11 of the carrying mechanism 10 can be located on the same circumference. For example, in the embodiment shown in Figure 3 , the first support portion 11a, the second support portion 11b, the third support portion 11c, and the fourth support portion 11d can be located on the same circumference. In some examples, the mounting table 12 can be a circular platform. In the embodiment shown in Figure 3 , the first support portion 11a, the second support portion 11b, the third support portion 11c, and the fourth support portion 11d can be evenly arranged on the outer periphery of the mounting table 12.

[0056] In some examples, the carrying mechanism 10 can push the bag-type container 100 to be uncapped to the front of the separating mechanism 20 along the left-right direction. In various embodiments, the "left-right direction" can be understood as a direction that is substantially orthogonal to the "up-down direction" and substantially orthogonal to the "front-rear direction". In the embodiment shown in Figure 3 , "towards the left" or "to the left" can be understood as the direction indicated by D5, and "towards the right" or "to the right" can be understood as the direction indicated by D6.

[0057] In some examples, the mounting table 12 is configured to be rotatable about an axis along the up-down direction, for example, can be rotated along the direction of D5 or D6 shown in Figure 3 to rotate the mounting table 12 of the support portion 11a, the support portion 11b, the support portion 11c, and the support portion 11d about the circumference, thereby pushing the bag-type container 100 to be uncapped to the front of the separating mechanism 20 from the left side or the right side (see Figure 3). In some examples, the carrying mechanism 10 can further include a rotary motor (not shown), which can be used to drive the mounting table 12 to rotate around an axis along the up-down direction, for example, along the D5 or D6 direction as shown. Figure 3

[0058] In some examples, the carrying mechanism 10 can cooperate with a conveying device 800 to receive the bag container 100 from the conveying device 800. The conveying device 800 can be a device for conveying the bag container 100, for example, from a storage cabinet (not shown) to the carrying mechanism 10. In the embodiment as shown, the conveying device 800 can convey the bag container 100 to the carrying mechanism 10 one by one along the D7 direction. For example, the conveying device 800 can be docked with the support portion 11 of the carrying mechanism 10, i.e., the output port (not shown) of the conveying device 800 is arranged opposite to the support portion 11 and engages, so as to convey the bag container 100 to the support portion 11 of the carrying mechanism 10 and hold in the U-shaped structure of the support portion 11. Figure 3

[0059] In addition, the carrying mechanism 10 can push the bag container 100 received from the conveying device 800 to the separating mechanism 20 for decapping by rotation, for example, the carrying mechanism can rotate along the D5 direction to push the bag container 100 received from the conveying device 800 to the separating mechanism 20 (see Figure 3 In this case, the cooperation of the decapping device 1 with the conveying device 800 can constitute a processing system for the bag container 100, which can be used to convey the bag container 100 and can be used to decap the bag container 100.

[0060] Figure 4A is a schematic view showing the separating mechanism 20 abutting against the cap 102 of the bag container 100 according to an example of the present disclosure; Figure 4B is a schematic view showing the separating mechanism 20 separating the cap 102 from the main body 101 of the bag container 100 according to an example of the present disclosure; Figure 4C is a schematic view showing the separating mechanism 20 separating the cap 102 from the main body 101 of the bag container 100 according to an example of the present disclosure.

[0061] In some examples, the separating mechanism 20 can include a first arm 21 and a second arm 22. In some examples, the first arm 21 and the second arm 22 can be arranged opposite to each other. In some examples, the first arm 21 and the second arm 22 can be arranged side by side. In some examples, the first arm 21 and the second arm 22 can be arranged in parallel. In some examples, the first arm 21 and the second arm 22 can be in the form of a thin plate (see Figure 4A Figure 4B and​​​Figure 4C ).

[0062] In some examples, the first arm 21 and the second arm 22 can have a predetermined interval therebetween. In some examples, the predetermined interval between the first arm 21 and the second arm 22 can be smaller than the maximum width of the cap 102 and can be larger than the minimum width at the connection between the neck 104 and the cap 102, and the first arm 21 and the second arm 22 can abut against the cap 102 from below the cap 102 and can be configured to abut against the cap 102 from the connection between the neck 104 and the cap 102. In some examples, the first arm 21 and the second arm 22 can abut against the cap 102 from below the cap 102. In this case, by abutting against the cap 102 from below the cap 102, it is possible to facilitate the application of a force to the cap 102 away from the main body 101.

[0063] In some examples, when uncapping the bag-type container 100, the first arm 21 and the second arm 22 of the separation mechanism 20 can abut against the cap 102 (see Figure 4B ), and the first arm 21 and the second arm 22 can move in a direction away from the main body 101 to separate the cap 102 from the main body 101 (see Figure 4C ). In some examples, the first arm 21 and the second arm 22 can abut against the cap 102 from below.

[0064] In some examples, the first arm 21 and the second arm 22 can move to below the cap 102 in the front-rear direction (see Figure 4A and Figure 4B ). In the embodiment shown in Figure 4A and Figure 4B , the first arm 21 and the second arm 22 can approach the cap 102 from far to near in the D3 direction and move to below the cap 102.

[0065] In some examples, the first arm 21 and the second arm 22 can rotate about an axis in the left-right direction to separate the cap 102 from the main body 101 (see Figure 4C ). In the embodiment shown in Figure 4C , the first arm 21 and the second arm 22 can rotate in the D8 direction to separate the cap 102 from the main body 101.

[0066] In some examples, the first arm 21 can include a first shaft 210, and a first resistance arm 211 and a first power arm 212 rotatable about the first shaft 210 and linked to each other, and the second arm 22 can include a second shaft 220, and a second resistance arm 221 and a second power arm 222 rotatable about the second shaft 220 and linked to each other (see Figure 4A , Figure 4B and Figure 4C). In this case, by the first resistance arm 211 and the first power arm 212 linked to each other and the second resistance arm 221 and the second power arm 222 linked to each other, it is possible to facilitate formation of a lever structure to cap the bag container 100.

[0067] In some examples, the first resistance arm 211, the first shaft 210, and the first power arm 212 of the first arm 21 can be formed into an L-shaped structure, and the second resistance arm 221, the second shaft 220, and the second power arm 222 of the second arm 22 can be formed into an L-shaped structure (see Figure 4A 、 Figure 4B and Figure 4C ). In this case, by the first arm 21 and the second arm 22 formed into an L-shaped structure, when the first resistance arm 211 and the second resistance arm 221 move along the front-rear direction, it is possible to facilitate driving of the first power arm 212 and the second power arm 222.

[0068] In some examples, the first resistance arm 211 and the second resistance arm 212 can be arranged substantially in parallel. That is, the distance between the first resistance arm 211 and the second resistance arm 212 at each position can be substantially kept equal. In some examples, the first power arm 212 and the second power arm 222 can be substantially parallel. In some examples, the structure of the first arm 21 and the structure of the second arm 22 can be the same. In some examples, the first shaft 210 and the second shaft 220 can be located on the same straight line. In some examples, the first arm 21 and the second arm 22 can be mirror-symmetrical.

[0069] In the embodiment shown in Figure 4A 、 Figure 4B and Figure 4C , by driving the first shaft 210 and the second shaft 220 towards the front, it is possible to drive the first resistance arm 211 and the second resistance arm 221 to the lower side of the cap 102 along the D3 direction (see Figure 4A and Figure 4B ); and by driving the first power arm 212 and the second power arm 222 towards the rear, it is possible to drive the first resistance arm 211 and the second resistance arm 221 to rotate along the D8 direction around the first shaft 210 and the second shaft 220, so that the first resistance arm 211 and the second resistance arm 212 move towards the direction away from the main body 101, thereby separating the cap 102 from the main body 101 (see Figure 4C ).

[0070] In some examples, when the first arm 21 and the second arm 22 are in an initial posture, for example, the posture shown in Figure 4A , the first resistance arm 211 and the second resistance arm 221 can be substantially along the front-rear direction, and the first power arm 212 and the second power arm 222 can be substantially along the up-down direction (see Figure 4A). Thus, the first resistance arm 211 and the second resistance arm 221 can be easily driven to the lower side of the cap 102 in the front-rear direction.

[0071] In some examples, the separation mechanism 20 can include a holding member (not shown) that returns the first arm 21 and the second arm 22 to the initial posture. The holding member can be configured to provide a return force to the first arm and the second arm to return to the initial posture. For example, the holding member can be configured to provide a pulling force toward the lower side of the first resistance arm 211 and the second resistance arm 221 or toward the front of the first power arm 212 and the second power arm 222. In this case, the first arm 21 and the second arm 22 can automatically return to the initial posture after the cap is removed, so as to facilitate the next cap removal operation. In some examples, the holding member can be an elastic holding member, such as a tension spring.

[0072] In other examples, the moment of force of gravity on the first resistance arm 211 can be greater than the moment of force of gravity on the first power arm 212, and the moment of force of gravity on the second resistance arm 221 can be greater than the moment of force of gravity on the second power arm 222. In this case, the first arm 21 and the second arm 22 can be returned to the initial posture by the action of gravity.

[0073] In some examples, the length of the first resistance arm 211 can be greater than the length of the first power arm 212. In some examples, the density of the first resistance arm 211 can be greater than the density of the first power arm 212. In some examples, the length of the second resistance arm 221 can be greater than the length of the second power arm 222. In some examples, the density of the second resistance arm 221 can be greater than the density of the second power arm 222.

[0074] Figure 5A is a schematic view showing that the bag-type container 100 related to the example of the present disclosure is located in front of the separation mechanism 20; Figure 5B is a schematic view showing that the drive mechanism 30 related to the example of the present disclosure drives the separation mechanism 20 to abut against the cap 102 of the bag-type container 100; Figure 5C is a schematic view showing that the drive mechanism 30 related to the example of the present disclosure drives the separation mechanism 20 to separate the cap 102 of the bag-type container 100 from the main body 101.

[0075] In some examples, the drive mechanism 30 can include a transmission shaft 31 (see Figure 1 ) driven by a driven motor (not shown).

[0076] In some examples, the drive mechanism 30 can drive the separation mechanism 20 to abut the first arm 21 and the second arm 22 of the separation mechanism 20 against the cap 102 (see Figure 5A and Figure 5B), and the driving mechanism 30 can drive the separating mechanism 20 to move the first arm 21 and the second arm 22 in a direction away from the main body 101 to separate the cap 102 from the main body 101 (see Figure 5C ).

[0077] In some examples, the driving mechanism 30 can be configured to drive the first arm 21 and the second arm 22 to move in the D3 direction to below the cap 102 (see Figure 5A and Figure 5B ), and the driving mechanism 30 can be configured to drive the first arm 21 and the second arm 22 to rotate in the D8 direction to separate the cap 102 from the main body 101 (see Figure 5C ).

[0078] In some examples, the first arm 21 can be connected to the transmission shaft 31 of the driving mechanism 30 through the first shaft 210, and the second arm 22 can be connected to the transmission shaft 31 of the driving mechanism 30 through the second shaft 220. In some examples, the driving mechanism 30 can drive the first shaft 210 and the second shaft 220 to move the first resistance arm 211 and the second resistance arm 221 to below the cap 102 (see Figure 5A and Figure 5B ), and drive the first power arm 212 and the second power arm 222 to rotate the first resistance arm 211 around the first shaft 210 and the second resistance arm 221 around the second shaft 220 in a direction away from the main body 101 (see Figure 5C ).

[0079] In some examples, the driving mechanism 30 can further include a guide portion 32 (see Figure 1 ). In some examples, the guide portion 32 can be arranged on the travel path of the first power arm 212 and the second power arm 222 (see Figure 5A , Figure 5B and Figure 5C ). In the embodiment shown in Figure 5A , Figure 5B and Figure 5C , the guide portion 32 can be arranged on the travel path of the first power arm 212 and the second power arm 222 moving in the D3 direction.

[0080] The driving mechanism 30 is configured to drive the first resistance arm 211 and the second resistance arm 212 to move in the D3 direction to below the cap 102 (see Figure 5A and Figure 5B ), when the first power arm 212 and the second power arm 222 reach the guide portion 32 and the first resistance arm 211 and the second resistance arm 221 continue to move forward (i.e., Figure 5A and Figure 5BWhen traveling in the direction indicated by D3, the guide unit 32 can guide the first power arm 212 and the second power arm 222 so that the first power arm 212 and the second power arm 222 have a travel component in the vertical direction, thereby giving the first resistance arm 211 and the second resistance arm 221 a travel component in the vertical direction (see...). Figure 5C ).exist Figure 5C In the embodiment shown, guided by the guide part 32, the first arm 21 and the second arm 22 can rotate along the D8 direction around the first axis 210 and the second axis 220 respectively, so that the first resistance arm 211 and the second resistance arm 221 move upward away from the main body 101, thereby separating the cap 102 from the main body 101.

[0081] In this case, by providing a guide unit 32 on the travel path that can guide the first power arm 212 and the second power arm 222, a drive mechanism 30 can generate forces in two dimensions.

[0082] In some examples, the guide unit 32 may have a guide direction intersecting the forward and backward direction (see [reference]). Figure 5A , Figure 5B and Figure 5C In some examples, the guiding direction of the guide unit 32 can be forward and diagonally downward (see...). Figure 5A , Figure 5B and Figure 5C In some other examples, the guiding direction of the guide section 32 can be along the vertical direction. In other examples, the guiding direction of the guide section 32 can be forward and diagonally upward.

[0083] In some examples, the guiding direction of the guide unit 32 can be along an oblique up-down direction. For example, in Figure 5A , Figure 5B and Figure 5C In the illustrated embodiment, the guiding direction of the guide unit 32 can be obliquely downward along the D3 direction. In this case, by guiding the first power arm 212 and the second power arm 222 to move along a guiding direction intersecting the front-back direction, the first resistance arm 211 and the second resistance arm 221 will have a travel component along the vertical direction.

[0084] In this embodiment, the guiding direction of the guide portion 32 can be the extending direction of the guiding surface of the guide portion 32. The guiding surface of the guide portion 32 can extend along the vertical direction or along an oblique vertical direction. For example, in Figure 5A , Figure 5B and Figure 5CIn the illustrated embodiment, the guide surface of the guide portion 32 can extend obliquely downward along the D3 direction. In this case, the first power arm 221 and the second power arm 222 can move along the guide surface of the guide portion 32, thereby being guided.

[0085] In some examples, the guide surface of the guide portion 32 can be a smooth plane. In other examples, the guide surface of the guide portion 32 can also be a smooth curved surface.

[0086] In some examples, the guide portion 32 can be provided on the left side and / or the right side of the transmission shaft 31.

[0087] In some examples, the end of the first power arm 212 away from the first resistance arm 211 can protrude toward the side away from the second power arm 222 to form an ear portion (not shown). In this case, by the ear portion toward the side, the guide portion 32 located on the side of the transmission shaft 31 can guide the first power arm 212. In some examples, the ear portion of the first power arm 212 can be cylindrical.

[0088] In some examples, the end of the second power arm 222 away from the second resistance arm 221 can protrude toward the side away from the first power arm 212 to form an ear portion (not shown). In this case, by the ear portion toward the side, the guide portion 32 located on the side of the transmission shaft 31 can guide the second power arm 222. In some examples, the ear portion of the second power arm 222 can be cylindrical.

[0089] In Figure 5A , Figure 5B and Figure 5C the illustrated embodiment, the guide portion 32 can guide the first power arm 212 and the second power arm 222 to have a travel component toward the downward direction, so that the first arm 21 and the second arm 22 are rotated along the D8 direction around the first shaft 210 and the second shaft 220, respectively, so that the first resistance arm 211 and the second resistance arm 221 have a travel component toward the upward direction.

[0090] In some examples, an avoiding space is provided on the transmission shaft 31 in a direction toward the rear and toward the downward direction, when the first power arm 212 and the second power arm 222 are guided by the guide portion 32 to move toward the rear and toward the downward direction relative to the first shaft 210 and the second shaft 220 (see Figure 6A , Figure 6B and Figure 6C ), by providing the avoiding space on the transmission shaft 31, the first power arm 212 and the second power arm 222 can be guided by the guide portion 32.

[0091] Figure 6Ais another example of a schematic diagram showing that the bag container 100 involved in the example of the present disclosure is located in front of the separation mechanism 20; Figure 6B is another example of a schematic diagram showing that the driving mechanism 30 involved in the example of the present disclosure drives the separation mechanism 20 to abut against the cap 102 of the bag container 100; Figure 6A is another example of a schematic diagram showing that the driving mechanism 30 involved in the example of the present disclosure drives the separation mechanism 20 to separate the cap 102 of the bag container 100 from the main body 101.

[0092] In some examples, the guiding direction of the guiding portion 32 can be towards the front (i.e., Figure 6B and Figure 6C the direction indicated by D3 in Figure 6A 、 Figure 6B and Figure 6C ) and obliquely upwards (see ).

[0093] In the embodiments shown in Figure 6A 、 Figure 6B and Figure 6C , the guiding portion 32 can guide the first power arm 212 and the second power arm 222 to have a travel component towards the upwards, so that the first resistance arm 211 and the second resistance arm 221 have a travel component towards the upwards, thereby separating the cap 102 from the main body 101.

[0094] In the embodiments shown in Figure 6A 、 Figure 6B and Figure 6C , the first arm 21 and the second arm 22 can be in a linear shape. In the embodiments shown in Figure 6A 、 Figure 6B and Figure 6C , the first arm 21 and the second arm 22 can be in a long plate shape. In some examples, the end of the first resistance arm 211 away from the first power arm 212 can have a rounded corner design. In some examples, the end of the second resistance arm 221 away from the second power arm 222 can have a rounded corner design.

[0095] In the embodiments shown in Figure 6A 、 Figure 6A and Figure 7A , when the first arm 21 and the second arm 22 are in an initial posture, for example, the posture shown in Figure 7B , the first resistance arm 211, the first power arm 212, the second resistance arm 221 and the second power arm 222 can be substantially along the front-back direction (see Figure 7A ).

[0096] Figure 7B and Figure 7Ais a schematic view showing the cooperation of the drive mechanism 30 with the carrying mechanism 10 according to an example of the present disclosure, wherein Figure 7B is a schematic view showing the drive mechanism 30 before moving towards the front, Figure 7A is a schematic view showing the drive mechanism 30 after moving towards the front.

[0097] In some examples, the drive mechanism 30 can comprise a base (not shown). In some examples, the base can be arranged stationary relative to the ground, and the base can be used to mount the drive motor and the guide portion 32. Thereby, it can be facilitated to provide support for the drive motor, the transmission shaft 31 and the guide portion 32. In other examples, the base can also be arranged as a separate component relative to the drive mechanism 30, and the carrying mechanism 10 and / or the drive mechanism 30 can be mounted to the base.

[0098] In some examples, the transmission shaft 31 of the drive mechanism 30 can have a strip-like shape, such as a prismatic shape, a cylindrical shape, etc. extending along an axial direction. The transmission shaft 31 can have a first end portion 311 connected to the separating mechanism 20 and a second end portion 312 opposite to the first end portion 311 (see Figure 7A and Figure 7B ).

[0099] In some examples, the carrying mechanism 10 is configured to be rotatable to position the first support portion 11a in front of the separating mechanism 20 and to position the third support portion 11c in front of the second end portion 312 (see Figure 7A ).

[0100] In the embodiment shown in Figure 7B and Figure 7A , the first support portion 11a can hold a bag container 100 to be uncapped, and the third support portion 11c can hold a bag container 100 that has been uncapped.

[0101] In some examples, the transmission shaft 31 is moved towards the front (i.e. in the direction indicated by D3 in Figure 7B ) to drive the first end portion 311 to uncap the bag container 100 carried by the first support portion 11a using the separating mechanism 20 and to drive the second end portion 312 to move away the bag container 100 carried by the third support portion 11c (see Figure 7B ). In this case, the bag container 100 carried by the first support portion 11a can be uncapped and the bag container 100 carried by the third support portion 11c can be moved away simultaneously by moving the transmission shaft 31 towards the front, thereby simplifying the structural design.

[0102] In some examples, as the transmission shaft 31 moves forward, the second end 312 of the transmission shaft 31 can abut against the neck 104 of the bag container 100 held by the third support portion 11c, and in turn be pushed away from the third support portion 11c by the second end 312 of the transmission shaft 31, thereby moving the uncapped bag container 100 away from the carrying mechanism 10.

[0103] In some examples, the carrying mechanism 10, the driving mechanism 30 can cooperate with a liquid preparation device 900 to push the uncapped bag container 100 to the liquid preparation device 900 (see Figure 8 and Figure 8 ). The liquid preparation device 900 can be a device for preparing a liquid medicine by the bag container 100, for example, mixing other liquid medicine with the liquid medicine in the bag container 100.

[0104] The carrying mechanism 10 can rotate the uncapped bag container 100 to the vicinity of the liquid preparation device 900 by rotation, and then the driving mechanism 30 can move the bag container 100 away from the carrying mechanism 10 and push it to the liquid preparation device 900 (see Figure 8 ). In this case, the cap removal device 1 cooperating with the conveying device 800 and the liquid preparation device 900 can constitute an automatic liquid preparation system which can be used for conveying the bag container 100, uncapping the bag container 100, and mixing other liquid medicine with the liquid medicine in the bag container 100.

[0105] In some examples, the cap removal device 1 can further include a recycling mechanism (not shown) disposed below the first arm 21 and the second arm 22. The removed cap 102 can slide to the recycling mechanism via the first arm 21 and the second arm 22 inclined along the oblique up-down direction. In this case, by the first arm 21 and the second arm 22 inclined along the oblique up-down direction and the recycling mechanism disposed below the first arm 21 and the second arm 22, the removed cap 102 can be conveniently recycled.

[0106] ​ is a flowchart showing the process of uncapping the bag container 100 by the cap removal device 1 according to the present example. Hereinafter, the process of uncapping the bag container 100 by the cap removal device 1 according to the present embodiment will be described in detail with reference to the accompanying ​ .

[0107] In the present embodiment, as shown in ​As shown, the process of uncapping the bag-type container 100 by the uncapping device 1 can include the following steps: fixing the bag-type container 100 to the carrying mechanism 10 (step S100); pushing the bag-type container 100 to be uncapped to the front of the separating mechanism 20 (step S200); driving the separating mechanism 20 to abut against the cap 102 of the bag-type container 100 (step S300); and driving the separating mechanism 20 to separate the cap 102 of the bag-type container 100 from the main body 101 (step S400).

[0108] In some examples, in step S100, the carrying mechanism 10 can hold the neck 104 of the bag-type container 100 by the support 11 involved in the examples of the present disclosure, thereby fixing the bag-type container 100. In step S100, the bag-type container 100 to be uncapped can be conveyed to the carrying mechanism 10 by the conveying device 800 involved in the examples of the present disclosure, and the support 11 of the carrying mechanism 10 can hold the neck 104 of the bag-type container 100 to be uncapped in a manner of exposing the cap 102 upward.

[0109] In some examples, in step S200, the carrying mechanism 10 can push the bag-type container 100 to the front of the separating mechanism 20 along the left-right direction by rotation.

[0110] In some examples, in step S300, the driving mechanism 30 can drive the separating mechanism 20 to move toward the front to abut against the cap 102 from below. In step S300, the driving mechanism 30 can drive the first shaft 210 and the second shaft 220 involved in the examples of the present disclosure to move toward the front, thereby abutting the first resistance arm 211 and the second resistance arm 221 against the cap 102 from below.

[0111] In some examples, in step S400, the driving mechanism 30 can drive the first arm 21 and the second arm 22 of the separating mechanism 20 to rotate upward around the shaft along the left-right direction to separate the cap 102 of the bag-type container 100 from the main body 101. In step S400, the driving mechanism 30 can drive the first shaft 210 and the second shaft 220 of the separating mechanism 20 toward the front, and guide the first power arm 212 and the second power arm 222 by the guide 32 provided on the travel path toward the front, so as to make the first arm 21 and the second arm 22 rotate around the first shaft 210 and the second shaft 220, respectively, thereby making the first resistance arm 211 and the second resistance arm 212 move toward the direction away from the main body 101, so as to separate the cap 102 of the bag-type container 100 from the main body 101. In addition, in step S400, the removed cap 102 can slide from the first resistance arm 211 and the second resistance arm 221 along the oblique up-down direction to the recycling mechanism.

[0112] Although the present disclosure has been specifically shown and described with reference to the accompanying drawings and examples, it will be understood by those skilled in the art that the above description is not in any way limiting to the present disclosure. Those skilled in the art can make modifications and changes to the present disclosure as needed without departing from the essential spirit and scope of the present disclosure, and such modifications and changes fall within the scope of the present disclosure.
