Description

[0001] This application is a divisional application of the patent application filed on April 28, 2021, with application number CN202110470385.8 and invention title "A Cap Removal Device for Bag Containers". Technical Field

[0002] This disclosure relates to a cap separation device. Background Technology

[0003] Intravenous infusion is a commonly used clinical medical method that delivers medications, nutritional solutions, and other fluids into the patient's body to aid in recovery. When patients require intravenous infusion, it is often necessary to mix different intravenous medications according to their condition to create a more effective treatment solution. In clinical practice, medical staff can transfer medications from different containers, such as ampoules or vials, into an infusion bag for mixing to obtain the desired treatment solution for the patient.

[0004] Currently, medical staff typically use manual methods to prepare and administer intravenous medications to patients. For example, when transferring medication into an infusion bag, the cap of the infusion bag is removed manually to transfer the medication into the bag.

[0005] However, due to the current shortage of medical personnel in healthcare institutions, manual operation is insufficient for efficiently preparing intravenous solutions when faced with large volumes of infusions. Therefore, there is a need for a device that can assist medical personnel in preparing infusions, particularly a device that can automatically remove the cap from the infusion bag. Summary of the Invention

[0006] This disclosure is made in view of the above-mentioned state of the prior art, and its purpose is to provide a cap removal device capable of automatically removing caps from bag-type containers.

[0007] To this end, this disclosure provides a cap removal device for a bag-type container, the bag-type container including a main body for containing material and a cap disposed on the main body, the cap removal device including a supporting mechanism, a separating mechanism, and a driving mechanism for driving the separating mechanism, the supporting mechanism being configured to fix the main body 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, the separating mechanism including a first arm and a second arm disposed opposite to each other, when the cap of the bag-type container is removed, the driving mechanism drives the separating mechanism so that the first arm and the second arm of the separating mechanism abut against the cap, and the driving mechanism drives the separating mechanism so that the first arm and the second arm move in a direction away from the main body to separate the cap from the main body.

[0008] In the cap removal device disclosed herein, a supporting mechanism secures the bag-type container to be capped, and a driving mechanism brings the first and second arms of the separating mechanism against the cap of the bag-type container. The first and second arms of the separating mechanism are then driven to move away from the main body of the bag-type container, thereby separating the cap from the main body. This allows for automated cap removal from the bag-type container.

[0009] Additionally, in the cap removal device disclosed herein, 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 abut against the cap from below. In this case, by abutting against the cap from below, it is convenient to apply a force to the cap away from the main body.

[0010] Additionally, in the cap removal device disclosed herein, optionally, the supporting mechanism is configured to push the bag-like container in the left-right direction to the front of the separating mechanism, the driving mechanism is configured to drive the first arm and the second arm to move in the front-back direction to below the cap, and the driving mechanism is configured to drive the first arm and the second arm to rotate about an axis in 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 about an axis in the left-right direction, an upward force can be provided to the first arm and the second arm to separate the cap from the main body.

[0011] Additionally, in the cap removal device disclosed herein, optionally, the driving mechanism includes an elongated drive shaft having a first end connected to the separating mechanism and a second end opposite to the first end. The supporting mechanism includes a first support portion and a second support portion for fixing the bag-type container, and the supporting mechanism is configured to be rotatable such that the first support portion is located in front of the first end and the second support portion is located in front of the second end. The drive shaft moves in a front-back direction so that the first end drives the separating mechanism to remove the cap from the bag-type container supported on the first support portion, and the second end removes the bag-type container supported on the second support portion from the second support portion. In this case, by moving the drive shaft in a front-back direction, the cap of the bag-type container supported on the first support portion and the bag-type container supported on the second support portion can be removed simultaneously, thereby simplifying the structural design.

[0012] Additionally, in the cap removal device disclosed herein, optionally, the first arm includes a first shaft, and a first resistance arm and a first power arm rotatable about the first shaft and linked to each other; the second arm includes a second shaft, and a second resistance arm and a second power arm rotatable about the second shaft and linked to each other; the first arm is rotatably connected to the drive mechanism via the first shaft, and the second arm is rotatably connected to the drive mechanism via the second shaft; the drive mechanism moves the first resistance arm and the second resistance arm below the cap by driving the first shaft and the second shaft, and drives the first power arm and the second power arm to rotate the first resistance arm about the first shaft and the second resistance arm about the second shaft in a direction away from the main body. In this case, the linked first resistance arm and first power arm, and the linked second resistance arm and second power arm, facilitate the formation of a lever structure for removing the cap from the bag-type container.

[0013] Additionally, in the cap removal device disclosed herein, optionally, the drive mechanism includes a guide portion located on the travel path of the first power arm and the second power arm. The drive mechanism drives the first resistance arm and the second resistance arm to move along the front-back direction to below the cap. 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 forward, the guide portion guides the first power arm and the second power arm so that the first power arm and the second power arm have a travel component along the vertical direction, thereby giving the first resistance arm and the second resistance arm a travel component along the vertical direction. In this case, by providing a guide portion on the travel path that can guide the first power arm and the second power arm, a single drive mechanism can generate forces in two dimensions.

[0014] Furthermore, in the cap removal device disclosed herein, optionally, the first resistance arm, first shaft, and first power arm of the first arm are formed in an L-shape, and the second resistance arm, second shaft, and second power arm of the second arm are also formed in an L-shape. In the initial posture, the first resistance arm and the second resistance arm are approximately along the front-back direction, and the first power arm and the second power arm are approximately along the up-down direction. In this case, by forming the first and second arms in an L-shape, it is convenient to guide the first and second power arms when they are moving forward.

[0015] Additionally, in the cap removal device disclosed herein, optionally, the separation mechanism further includes a retaining member for returning the first arm and the second arm to the initial posture. The retaining member is configured to provide a restoring force either downwards toward the first resistance arm and the second resistance arm or forwards toward the first power arm and the second power arm. In this case, after cap removal is completed, the first arm and the second arm can automatically return to their initial state to facilitate the next cap removal operation.

[0016] Additionally, the cap removal device disclosed herein may optionally include a retrieval mechanism disposed below the first arm and the second arm, wherein the removed cap slides down to the retrieval mechanism via the first and second arms, which are inclined in an oblique vertical direction. In this case, the removal of the cap can be easily retrieved by the first and second arms, which are inclined in an oblique vertical direction, and the retrieval mechanism disposed below the first and second arms.

[0017] Furthermore, in the cap removal device disclosed herein, optionally, the main body of the bag-type container includes a receiving portion having a receiving chamber and a neck having a hollow channel communicating with the receiving chamber for material flow, the cap being disposed at the opening of the neck, and the supporting mechanism fixing the main body by clamping the neck in a vertical direction. In this case, by clamping the neck in a vertical direction, it is easier to use the weight of the main body itself to fix it more stably.

[0018] According to the cap removal device disclosed herein, the caps of bagged containers can be removed automatically. Attached Figure Description

[0028] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or the shapes of the components may differ from actual figures.

[0029] It should be noted that the terms "comprising" and "having" and any variations thereof in this disclosure, such as a process, method, system, product, or device that includes or has a series of steps or units, are not necessarily limited to those steps or units that are explicitly listed, but may include or have other steps or units that are not explicitly listed or that are inherent to such processes, methods, products, or devices.

[0030] Furthermore, the subheadings and similar terms used in the following description of this disclosure are not intended to limit the content or scope of this disclosure; they are merely intended to serve as reading prompts. Such subheadings should not be construed as dividing the content of the article, nor should the content under a subheading be limited to the scope of that subheading.

[0031] This embodiment relates to a cap removal device for bag containers, which can be used to automatically remove the caps of bag containers during the processing of bag containers or the preparation of pharmaceutical solutions. The cap removal device for bag containers can be simply referred to as a cap removal device, or a cap removal device, cap removal device, automatic cap separation device for bag containers, or cap separation device, etc. The cap removal device involved in this embodiment can also be used in bag container processing systems or automatic liquid preparation systems to facilitate automated processing of bag containers or automated preparation of pharmaceutical solutions. With the cap removal device involved in this embodiment, the caps of bag containers can be automatically removed.

[0032] Hereinafter, with reference to the accompanying drawings, the cap removal device for the bag-type container according to this embodiment will be described in detail.

[0033] Figure 1 This is a schematic diagram showing the overall shape of the cap removal device 1 and the bag container 100 according to the example of this embodiment. It should be noted that relative position and direction terms such as "above", "facing upward", "below", "facing downward", "up and down direction", "left side", "facing left side", "left", "facing left", "right side", "facing right", "right", "facing right", "left and right direction", "front", "facing forward", "back", "facing backward", and "front and back direction" are used with reference to the normal operating posture and should not be considered as limiting.

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

[0035] In some examples, the body 101 of the bag container 100 may include a receiving portion 103 having a receiving chamber (not shown) and a neck 104 having a hollow channel (not shown) and communicating with the receiving chamber for material flow (see [link to relevant documentation]). Figure 1 In some examples, the cap 102 may be positioned at the opening of the neck 104 (see [reference]). Figure 1 ).

[0036] In this embodiment, the hollow channel of the neck 104 can be filled with a soft, puncturable, or easily puncturable object, such as a rubber stopper, and the cap 102 can be a hard, non-puncturable object, such as a rigid plastic cap. By using the cap removal device 1 of this embodiment to separate the cap 102 from the neck 104, it is convenient for medical personnel to perform subsequent operations, such as using a needle to puncture the rubber stopper in the hollow channel to retrieve the medication contained in the receiving chamber.

[0037] In some examples, the neck 104 may be cylindrical. In some examples, the neck 104 may comprise two or more cylindrical segments with different diameters. That is, in some examples, the neck 104 may be formed by stacking two or more cylindrical segments with different diameters. In some examples, the cap 102 may be disc-shaped. In some examples, the diameter of the connection between the neck 104 and the cap 102 may be smaller than the diameter of the cap 102. In some examples, the minimum width of the connection between the neck 104 and the cap 102 may 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 this embodiment, the cap removal device 1 may include a supporting mechanism 10, a separating mechanism 20, and a driving mechanism 30 for driving the separating mechanism 20 (see [link to documentation]). Figure 1 The supporting mechanism 10 can be configured to fix the main body 101 with the cap 102 exposed, and the separating mechanism 20 can be configured to separate the cap 102 of the bag container 100 from the main body 101. When the cap of the bag container 100 is removed, the driving mechanism 30 can drive the separating mechanism 20 so that the separating mechanism 20 abuts against the cap 102, and the driving mechanism 30 can drive the separating mechanism 20 to move in a direction away from the main body 101 to separate the cap 102 from the main body 101.

[0040] In the cap removal device 1 according to this embodiment, the bag container 100 to be capped is fixed by the supporting mechanism 10, the separation mechanism 20 is brought into contact with the cap 102 of the bag container 100 by the driving mechanism 30, and the separation mechanism 20 is driven to move away from the main body 101 of the bag container 100, thereby separating the cap 102 of the bag container 100 from the main body 101. Thus, the cap 102 of the bag container 100 can be removed automatically.

[0041] Figure 2 This is a schematic diagram showing the support portion 11 of the load-bearing mechanism 10.

[0042] In some examples, the load-bearing mechanism 10 may include a U-shaped support portion 11 (see [reference]). Figure 2In some examples, the neck 104 of the bag container 100 can be held in a U-shaped support portion 11. In some examples, the support mechanism 10 can secure the main body 101 by holding the neck 104 of the bag container 100. In some examples, the support mechanism 10 can secure the main body 101 by holding the neck 104 in a vertical direction. Figure 1 In the illustrated embodiment, the cap 102 faces upward (D1) relative to the main body 101, and the main body 101 faces downward (D2) relative to the cap 102. In this case, by clamping the neck 104 along the vertical direction, it is easy to use the weight of the main body 101 itself to fix it more stably.

[0043] In various embodiments, "up and down direction" can be understood as the direction from the main body 101 of the bag container 100 to the cap 102 or the direction from the cap 102 of the bag container 100 to the main body 101; "upward" can be understood as the direction from the main body 101 to the cap 102; and "downward" can be understood as the direction from the cap 102 to the main body 101. Figure 1 In the illustrated embodiment, "facing upward" can be understood as the direction indicated by D1; "facing downward" can be understood as the direction indicated by D2.

[0044] In various embodiments, "forward and backward direction" can be understood as the direction from the separating mechanism 20 to the supporting mechanism 10 or from the supporting mechanism 10 to the separating mechanism 20; "facing forward" can be understood as the direction from the separating mechanism 20 to the supporting mechanism 10; and "facing backward" can be understood as the direction from the supporting mechanism 10 to the separating mechanism 20. Figure 1 In the illustrated embodiment, "facing forward" can be understood as the direction indicated by D3, and "facing backward" can be understood as the direction indicated by D4.

[0045] In some examples, the support portion 11 may include a first support plate 111 and a second support plate 112 disposed opposite to each other (see Figure 2 In some examples, a first elastic portion 113 may be provided on the inner side of the first support plate 111, and a second elastic portion 114 may be provided on the inner side of the second support plate 112 (see...). Figure 2 In some examples, the first elastic portion 113 and the second elastic portion 114 may be arranged opposite each other along the direction traversing the U-shaped structure. In this case, the first elastic portion 113 and the second elastic portion 114 generate an inward elastic force, thereby enabling a more stable grip on the neck 104 of the bag container 100.

[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 104 is held between the first support plate 111 and the second support plate 112, the elasticity of the first support plate 111 and the second support plate 112 can more stably hold the neck 104. In some examples, the first support plate 111 and the second support plate 112 can be flexible plates. This reduces damage to the neck 104.

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

[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 distance between the first support plate 111 and the second support plate 112 can gradually decrease from the inside to the outside. That is, the U-shaped structure formed by the first support plate 111 and the second support plate 112 can tend to be closed, with the first support plate 111 and the second support plate 112 close to each other at the opening of the U-shaped structure. This helps to stably hold the neck 104 of the bag 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 may have chamfered, for example, rounded corners, at the opening of the U-shaped structure. This allows the neck 104 of the bag container 100 to be easily pushed from the outside in and held between the first support plate 111 and the second support plate 112.

[0050] In some examples, the distance between the first support plate 111 and the second support plate 112 can gradually decrease from the closed portion of the U-shaped structure to the first elastic portion 113 and the second elastic portion 114, and can gradually increase 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 facilitates pushing the neck 104 between 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 facilitates holding the neck 104 in place.

[0051] In other examples, the first support plate 111 and the second support plate 112 can be configured to move in opposite directions. For example, the first support plate 111 and the second support plate 112 can be configured to be driven in opposite directions. Thus, the main body 101 can be fixed by clamping the neck 104.

[0052] Figure 3 A schematic diagram showing the cooperation between the carrying mechanism 10, the separating mechanism 20, and the conveying device 800 is shown.

[0053] In some examples, the load-bearing mechanism 10 may include a plurality of support portions 11 (see Figure 3 In some examples, the number of supports 11 in the load-bearing mechanism 10 can be 2, 4, or 8. For example, in Figure 3 In the illustrated embodiment, the support portion 11 may 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 support mechanism 10 may include a mounting platform 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 may be evenly arranged on the mounting platform 12 (see [reference]). Figure 3 ).

[0055] In some examples, the multiple supports 11 of the load-bearing mechanism 10 may be located on the same circumference. For example, in Figure 3 In the illustrated embodiment, the first support portion 11a, the second support portion 11b, the third support portion 11c, and the fourth support portion 11d may be located on the same circumference. In some examples, the mounting platform 12 may be a circular platform. Figure 3 In the illustrated embodiment, 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 platform 12.

[0056] In some examples, the supporting mechanism 10 can push the bag container 100 to be decapped to the front of the separating mechanism 20 in a left-right direction. In various embodiments, "left-right direction" can be understood as a direction that is approximately orthogonal to the "up-down direction" and approximately orthogonal to the "front-back direction". Figure 3 In the illustrated embodiment, "facing left" or "facing the left side" can be understood as the direction indicated by D5, and "facing right" or "facing the right side" can be understood as the direction indicated by D6.

[0057] In some examples, the mounting platform 12 is configured to rotate about an axis in the vertical direction, for example, along... Figure 3 Rotating in the direction of D5 or D6 as shown causes the mounting platforms 12 of supports 11a, 11b, 11c, and 11d to rotate circumferentially, thereby pushing the bag container 100 to be decapped from the left or right side to the front of the separating mechanism 20 (see...). Figure 3In some examples, the support mechanism 10 may also include a rotary motor (not shown) that can drive the mounting platform 12 to rotate about an axis in the vertical direction, for example along... Figure 3 Rotate in the direction shown as D5 or D6.

[0058] In some examples, the carrier 10 can cooperate with the 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, conveying the bag container 100 from a storage tank (not shown) to the carrier 10. Figure 3 In the illustrated embodiment, the conveying device 800 can convey the bag containers 100 one by one to the carrying mechanism 10 along the D7 direction. For example, the conveying device 800 can dock with the support portion 11 of the carrying mechanism 10, that is, the output port (not shown) of the conveying device 800 is arranged opposite to and engaged with the support portion 11, thereby conveying the bag containers 100 to the support portion 11 of the carrying mechanism 10 and holding them in the U-shaped structure of the support portion 11.

[0059] Additionally, the carrying mechanism 10 can rotate to push the bag container 100 received from the conveying device 800 to the separating mechanism 20 for cap removal. 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 cap removal device 1, in conjunction 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 to remove the cap from the bag container 100.

[0060] Figure 4A This is a schematic diagram showing the separation mechanism 20 of the present disclosure abutting against the cap 102 of the bag container 100; Figure 4B This is a schematic diagram showing the separation mechanism 20 involved in the present disclosure separating the cap 102 of the bag container 100 from the body portion 101; Figure 4C This is a schematic diagram showing the separation mechanism 20 involved in the present disclosure separating the cap 102 of the bag container 100 from the body portion 101.

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

[0062] In some examples, a predetermined distance may exist between the first arm 21 and the second arm 22. In some examples, the predetermined distance between the first arm 21 and the second arm 22 may be less than the maximum width of the cap 102 and greater 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 may abut against the cap 102 from below, 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 may abut against the cap 102 from below. In this case, by abutting against the cap 102 from below, it is convenient to apply a force to the cap 102 away from the main body 101.

[0063] In some examples, when the cap of the bag container 100 is removed, the first arm 21 and the second arm 22 of the separating mechanism 20 can abut against the cap 102 (see [link]). Figure 4B Furthermore, 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 along the front-back direction to below the cap 102 (see...). Figure 4A and Figure 4B ).exist Figure 4A and Figure 4B In the embodiment shown, the first arm 21 and the second arm 22 can approach the cap 102 from far to near along 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 body 101 (see [link]). Figure 4C ).exist Figure 4C In the embodiment shown, the first arm 21 and the second arm 22 can rotate along the D8 direction to separate the cap 102 from the main body 101.

[0066] In some examples, the first arm 21 may include a first shaft 210, and a first resistance arm 211 and a first power arm 212 that are rotatable about the first shaft 210 and linked to each other; the second arm 22 may include a second shaft 220, and a second resistance arm 221 and a second power arm 222 that are rotatable about the second shaft 220 and linked to each other (see [link to previous examples]). Figure 4A , Figure 4B and Figure 4CIn this case, the first resistance arm 211 and the first power arm 212, which are linked together, and the second resistance arm 221 and the second power arm 222, which are linked together, can easily form a lever structure to remove the cap from 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 [reference]). Figure 4A , Figure 4B and Figure 4C In this case, by forming the first arm 21 and the second arm 22 into an L-shaped structure, the first resistance arm 211 and the second resistance arm 221 can be easily driven when they move in the front-back direction.

[0068] In some examples, the first resistance arm 211 and the second resistance arm 212 can be arranged substantially parallel. That is, the distance between the first resistance arm 211 and the second resistance arm 212 at various positions can remain substantially 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] exist Figure 4A , Figure 4B and Figure 4C In the illustrated embodiment, by driving the first shaft 210 and the second shaft 220 forward, the first resistance arm 211 and the second resistance arm 221 can be driven along the D3 direction to below the cap 102 (see [reference]). Figure 4A and Figure 4B Furthermore, by driving the first power arm 212 and the second power arm 222 rearward, the first resistance arm 211 and the second resistance arm 221 can be driven to rotate about the first axis 210 and the second axis 220 along the D8 direction, so that the first resistance arm 211 and the second resistance arm 212 move in a 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 the initial posture, for example Figure 4A As shown, the first resistance arm 211 and the second resistance arm 221 can be roughly along the front-back direction, and the first power arm 212 and the second power arm 222 can be roughly along the vertical direction (see...). Figure 4AThis allows the first resistance arm 211 and the second resistance arm 221 to be easily driven under the cap 102 in the front-back direction.

[0071] In some examples, the separation mechanism 20 may include a retaining member (not shown) that returns the first arm 21 and the second arm 22 to their initial positions. The retaining member may be configured to provide a restoring force to the first and second arms to their initial positions. For example, the retaining member may be configured to provide traction downwards toward the first resistance arm 211 and the second resistance arm 221 or forwards toward the first power arm 212 and the second power arm 222. In this configuration, the first arm 21 and the second arm 22 can automatically return to their initial positions after the cap removal is completed, facilitating the next cap removal operation. In some examples, the retaining member may be an elastic tension member, such as a tension spring.

[0072] In other examples, the torque of gravity on the first resistance arm 211 can be greater than the torque of gravity on the first power arm 212, and the torque of gravity on the second resistance arm 221 can be greater than the torque of gravity on the second power arm 222. In this case, gravity can restore the first arm 21 and the second arm 22 to their initial positions.

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

[0074] Figure 5A This is a schematic diagram showing the bag container 100, as described in this disclosure example, located in front of the separation mechanism 20; Figure 5B This is a schematic diagram showing the drive mechanism 30 driving the separation mechanism 20 to abut against the cap 102 of the bag container 100, as described in the example of this disclosure. Figure 5C This is a schematic diagram showing how the drive mechanism 30 drives the separation mechanism 20 to separate the cap 102 of the bag container 100 from the main body 101, as described in the example of this disclosure.

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

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

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

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

[0079] In some examples, the drive mechanism 30 may also include a guide section 32 (see Figure 1 In some examples, the guide 32 may be positioned on the travel path of the first power arm 212 and the second power arm 222 (see [reference]). Figure 5A , Figure 5B and Figure 5C ).exist Figure 5A , Figure 5B and Figure 5C In the embodiment shown, the guide unit 32 may be disposed on the travel path of the first power arm 212 and the second power arm 222 moving along the D3 direction.

[0080] Drive mechanism 30 is configured to drive the first resistance arm 211 and the second resistance arm 212 to move along the D3 direction 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 section 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 and thus be guided.

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

[0086] In some examples, the guide 32 may be located on the left and / or right side of the drive shaft 31.

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

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

[0089] exist Figure 5A , Figure 5B and Figure 5C In the illustrated embodiment, 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 downward travel component, so that the first arm 21 and the second arm 22 rotate about the first axis 210 and the second axis 220 in the D8 direction, so that the first resistance arm 211 and the second resistance arm 221 have an upward travel component.

[0090] In some examples, clearance space is provided on drive shaft 31 in a rearward and downward direction when the first drive arm 212 and the second drive arm 222 are guided by guide 32 and move rearward and downward relative to the first shaft 210 and the second shaft 220 (see Figure 5A , Figure 5B and Figure 5C By providing clearance space on the drive shaft 31, the first power arm 212 and the second power arm 222 can be easily guided by the guide part 32.

[0091] Figure 6AThis is a schematic diagram showing another example of a bag container 100 located in front of a separation mechanism 20, as described in this disclosure. Figure 6B This is a schematic diagram illustrating another example of a drive mechanism 30 driving a separation mechanism 20 to abut against a cap 102 of a bag container 100, as described in this disclosure. Figure 6C This is a schematic diagram illustrating another example of how the drive mechanism 30 drives the separation mechanism 20 to separate the cap 102 of the bag container 100 from the body portion 101, as described in this disclosure example.

[0092] In some examples, the guiding direction of the guide unit 32 can be forward (i.e., Figure 6A and Figure 6B (as indicated by D3) and diagonally upwards (see...) Figure 6A , Figure 6B and Figure 6C ).

[0093] exist Figure 6A , Figure 6B and Figure 6C In the embodiment shown, the guide 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 an upward travel component, thereby giving the first resistance arm 211 and the second resistance arm 221 an upward travel component, thereby separating the cap 102 from the main body 101.

[0094] exist Figure 6A , Figure 6B and Figure 6C In the illustrated embodiment, the first arm 21 and the second arm 22 can be in a straight line. Figure 6A , Figure 6B and Figure 6C In the illustrated embodiments, the first arm 21 and the second arm 22 may be in the form of long plates. In some examples, the end of the first resistance arm 211 away from the first power arm 212 may have a rounded corner design. In some examples, the end of the second resistance arm 221 away from the second power arm 222 may have a rounded corner design.

[0095] exist Figure 6A , Figure 6B and Figure 6C In the illustrated embodiment, when the first arm 21 and the second arm 22 are in their initial posture, for example... Figure 6A As shown, the first resistance arm 211, the first power arm 212, the second resistance arm 221, and the second power arm 222 can be roughly along the front-back direction (see...). Figure 6A ).

[0096] Figure 7A and Figure 7BThis is a schematic diagram showing the cooperation between the drive mechanism 30 and the support mechanism 10 according to the example of this disclosure, wherein Figure 7A A schematic diagram is shown before the drive mechanism 30 moves forward. Figure 7B A schematic diagram is shown after the drive mechanism 30 moves forward.

[0097] In some examples, the drive mechanism 30 may include a base (not shown). In some examples, the base may be stationary relative to the ground and may be used to mount the drive motor and guide 32. This facilitates the provision of support for the drive motor, drive shaft 31, and guide 32. In other examples, the base may also be a component independent of the drive mechanism 30, on which the support mechanism 10 and / or the drive mechanism 30 may be mounted.

[0098] In some examples, the drive shaft 31 of the drive mechanism 30 can be elongated, such as a prism or cylinder extending axially. The drive shaft 31 can have a first end 311 connected to the separating mechanism 20 and a second end 312 opposite to the first end 311 (see [link to documentation]). Figure 7A and Figure 7B ).

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

[0100] exist Figure 7A and Figure 7B In the embodiment shown, the first support portion 11a can hold the bag container 100 to be capped, and the third support portion 11c can hold the bag container 100 with the cap already removed.

[0101] In some examples, the drive shaft 31 faces forward (i.e., Figure 7A The first end 311 moves in the direction indicated by D3 to drive the separation mechanism 20 to remove the cap from the bag container 100 supported on the first support 11a, and causes the second end 312 to remove the bag container 100 supported on the third support 11c (see...). Figure 7B In this case, by moving the drive shaft 31 forward, the cap on the bag container 100 supported on the first support 11a can be removed and the bag container 100 supported on the third support 11c can be moved away simultaneously, thereby simplifying the structural design.

[0102] In some examples, as the drive shaft 31 moves forward, the second end 312 of the drive shaft 31 may abut against the neck 104 of the bag container 100 held by the third support 11c, and then be pushed away from the third support 11c by the second end 312 of the drive shaft 31, thereby removing the capless bag container 100 from the carrying mechanism 10.

[0103] In some examples, the support mechanism 10 and the drive mechanism 30 can cooperate with the dispensing device 900 to push the capped bag container 100 to the dispensing device 900 (see [link]). Figure 7A and Figure 7B The dispensing device 900 can be a device for dispensing a medicine solution via the bag container 100, for example, mixing other medicine solutions with the medicine solution in the bag container 100.

[0104] The carrying mechanism 10 can rotate the capped bag container 100 to the vicinity of the dispensing device 900 by rotation, and then the drive mechanism 30 can remove the bag container 100 from the carrying mechanism 10 and push it to the dispensing device 900 (see...). Figure 7B In this case, the decapping device 1, together with the conveying device 800 and the dispensing device 900, can constitute an automatic dispensing system. This automatic dispensing system can be used to convey the bag container 100, decap the bag container 100, and mix other liquids with the liquids in the bag container 100.

[0105] In some examples, the cap removal device 1 may also include a retrieval mechanism (not shown) disposed below the first arm 21 and the second arm 22. The removed cap 102 can slide down to the retrieval mechanism via the first arm 21 and the second arm 22, which are inclined in an oblique vertical direction. In this case, the removal of the cap 102 can be easily retrieved by the first arm 21 and the second arm 22, which are inclined in an oblique vertical direction, and by the retrieval mechanism disposed below the first arm 21 and the second arm 22.

[0106] Figure 8 This is a schematic diagram illustrating the process of removing the cap from a bag container 100 using the cap-removing device 1 according to an example of this disclosure. The following, in conjunction with the attached... Figure 8 This document details the process of removing the cap from a bag container 100 using the cap-removing device 1 described in this embodiment.

[0107] In this embodiment, such as Figure 8As shown, the process of removing the cap from the bag container 100 using the cap removal device 1 may include the following steps: fixing the bag container 100 to the carrying mechanism 10 (step S100); pushing the bag container 100 to be capped to the front of the separating mechanism 20 (step S200); driving the separating mechanism 20 to abut against the cap 102 of the bag container 100 (step S300); driving the separating mechanism 20 to separate the cap 102 of the bag 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 container 100 by means of the support portion 11 as described in the present disclosure, thereby fixing the bag container 100. In step S100, the bag container 100 to be decapped can be conveyed to the carrying mechanism 10 by means of the conveying device 800 as described in the present disclosure, and the support portion 11 of the carrying mechanism 10 can hold the neck 104 of the bag container 100 to be decapped with the cap 102 exposed upwards.

[0109] In some examples, in step S200, the carrying mechanism 10 can push the bag container 100 in the left-right direction by rotating.

[0110] In some examples, in step S300, the drive mechanism 30 may drive the separation mechanism 20 to move forward so as to abut against the cap 102 from below. In step S300, the drive mechanism 30 may abut against the cap 102 from below by driving the first shaft 210 and the second shaft 220 involved in the examples of this disclosure forward.

[0111] In some examples, in step S400, the drive mechanism 30 can drive the first arm 21 and the second arm 22 of the separation mechanism 20 to rotate upward about an axis in the left-right direction to separate the cap 102 of the bag container 100 from the main body 101. In step S400, the drive mechanism 30 can drive the first axis 210 and the second axis 220 of the separation mechanism 20 forward, and guide the first power arm 212 and the second power arm 222 via a guide portion 32 provided on the forward travel path, so that the first arm 21 and the second arm 22 rotate about the first axis 210 and the second axis 220 respectively, thereby moving the first resistance arm 211 and the second resistance arm 212 away from the main body 101, thereby separating the cap 102 of the bag container 100 from the main body 101. Additionally, in step S400, the removed cap 102 can slide from the first resistance arm 211 and the second resistance arm 221 in the oblique up-down direction to the recycling mechanism.

[0112] While the present disclosure has been specifically described above in conjunction with the accompanying drawings and examples, it is to be understood that the foregoing description does not limit the present disclosure in any way. Those skilled in the art can make modifications and variations to the present disclosure as needed without departing from its essential spirit and scope, and all such modifications and variations shall fall within the scope of the present disclosure.
