Hereinafter, a decapping device for a bag container according to the present embodiment will be described in detail with reference to the drawings.

Fig. 1 is an overall schematic view showing a decapping device 1 and a bag-type container 100 according to an example of the present embodiment. It should be noted that relative position and relative direction terms such as "above", "upward", "downward", "up-down", "left", "right", "left", "right", "front", "forward", "rearward", "forward-rearward" and the like refer to normal operation postures and should not be considered as restrictive.

In this embodiment, bag-type container 100 may include a body portion 101 for containing a material and a cap 102 (see fig. 1) disposed on body portion 101. In some examples, the material contained in the body portion 101 may be a liquid material, such as saline, glucose solution, medical fluid, blood, or the like. In other examples, the material contained in the body portion 101 may also be a powder material.

In some examples, body portion 101 of bag-type container 100 may include a receptacle 103 having a receptacle chamber (not shown) and a neck 104 having a hollow passage (not shown) and in communication with the receptacle chamber for material communication (see fig. 1). In some examples, the cap 102 can be disposed at the opening of the neck 104 (see fig. 1).

In this embodiment, the hollow channel of the neck 104 may be filled with a soft, pierceable or easily pierceable item, such as a rubber plug, and the cap 102 may be a hard, non-pierceable item, such as a hard plastic cover plate. By separating the cap 102 from the neck 104 by the uncapping device 1 according to the present embodiment, a medical staff or the like can perform subsequent operations, such as piercing a plug in the hollow passage with a needle tube, to take out the liquid medicine contained in the containing chamber.

In some examples, the neck 104 may be cylindrical. In some examples, the neck 104 may include two or more cylindrical segments of different diameters. That is, in some examples, the neck 104 may be formed from a stack of two or more cylindrical segments of different diameters. In some examples, the cap 102 may be pie-shaped. In some examples, the diameter of the connection between the neck 104 and the cap 102 may be less than the diameter of the cap 102. In some examples, the minimum width of the connection between the neck 104 and the cap 102 can be less than the maximum width of the cap 102.

In some examples, bag-type container 100 may be an infusion bag.

In the present embodiment, the decapping device 1 may include a carrying mechanism 10, a separating mechanism 20, and a driving mechanism 30 for driving the separating mechanism 20 (see fig. 1). Wherein the carrier mechanism 10 may be configured to fix the body portion 101 in such a manner that the cap 102 is exposed, and the separation mechanism 20 may be configured to separate the cap 102 from the body portion 101 of the bag-type container 100. When uncapping the bag-type container 100, the driving mechanism 30 may drive the separation mechanism 20 so that the separation mechanism 20 abuts against the cap 102, and the driving mechanism 30 may drive the separation 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.

In the decapping apparatus 1 according to the present embodiment, the bag container 100 to be decapped is fixed by the mount mechanism 10, the separation mechanism 20 is brought into contact with the cap 102 of the bag container 100 by the drive mechanism 30, and the separation mechanism 20 is driven to move away from the body 101 of the bag container 100, thereby separating the cap 102 of the bag container 100 from the body 101. This enables automated removal of the cap 102 of the bag-type container 100.

Fig. 2 is a schematic view showing the support portion 11 of the bearing mechanism 10.

In some examples, the load bearing mechanism 10 may include a support portion 11 in a U-shape (see fig. 2). In some examples, neck 104 of bag-type container 100 may be captured in U-shaped support portion 11. In some examples, the carrier mechanism 10 may secure the body portion 101 by gripping the neck portion 104 of the bag container 100. In some examples, the load bearing mechanism 10 may catch the neck 104 in an up-down direction to secure the body portion 101. In the embodiment shown in fig. 1, the cap 102 faces upward D1 with respect to the body 101, and the body 101 faces downward D2 with respect to the cap 102. In this case, by sandwiching the neck portion 104 in the up-down direction, it is possible to facilitate fixing thereof more stably by utilizing the gravity of the main body portion 101 itself.

In various embodiments, "up-down direction" may be understood as a direction from the body portion 101 of the bag-type container 100 toward the cap 102 or a direction from the cap 102 of the bag-type container 100 toward the body portion 101, "upward" may be understood as a direction from the body portion 101 toward the cap 102, and "downward" may be understood as a direction from the cap 102 toward the body portion 101. In the embodiment shown in fig. 1, "upward facing" may be understood as the direction indicated by D1; "downwardly facing" is to be understood as the direction indicated by D2.

In various embodiments, "forward-rearward direction" may be understood as a direction directed by the separating mechanism 20 toward the carrier mechanism 10 or by the carrier mechanism 10 toward the separating mechanism 20, "forward-facing" may be understood as a direction directed by the separating mechanism 20 toward the carrier mechanism 10, and "rearward-facing" may be understood as a direction directed by the carrier mechanism 10 toward the separating mechanism 20. In the embodiment shown in fig. 1, "forward" may be understood as the direction indicated by D3, and "rearward" may be understood as the direction indicated by D4.

In some examples, the support part 11 may include a first support plate 111 and a second support plate 112 (see fig. 2) that are oppositely disposed. In some examples, a first elastic part 113 may be provided at an inner side of the first support plate 111, and a second elastic part 114 may be provided at an inner side of the second support plate 112 (see fig. 2). In some examples, the first elastic part 113 and the second elastic part 114 may be oppositely disposed in a direction crossing the U-shaped structure. In this case, an elastic force is generated toward the inside by the first and second elastic parts 113 and 114, whereby the neck portion 104 of the bag-type container 100 can be more stably held.

In some examples, the first and second support plates 111 and 112 may be elastic plates. In this case, when the neck 104 is caught between the first and second support plates 111 and 112, the neck 104 can be more stably caught by the elasticity of the first and second support plates 111 and 112. In some examples, the first and second support plates 111 and 112 may be flexible plates. This can reduce damage to the neck 104.

In some examples, the first and second support plates 111 and 112 may be plate-shaped.

In some examples, the first and second support plates 111 and 112 may be in the form of a flat sheet.

In some examples, the first support plate 111 and the second support plate 112 may be arranged side by side.

In some examples, the first support plate 111 and the second support plate 112 may be disposed in parallel. In other examples, the spacing between the first and second support plates 111, 112 may taper from the inside to the outside. That is, the U-shaped structure formed by the first supporting plate 111 and the second supporting plate 112 may tend to close, and the first supporting plate 111 and the second supporting plate 112 are 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.

In some examples, the first and second support plates 111, 112 may have a chamfered, e.g., rounded, design at the opening of the U-shaped structure. Thereby, it can be facilitated to push the neck 104 of the bag-type container 100 from the outside inwards between the first support plate 111 and the second support plate 112 and to be retained therein.

In some examples, the distance between the first support plate 111 and the second support plate 112 may gradually decrease from the closed position of the U-shaped structure to the first elastic part 113 and the second elastic part 114, and may gradually increase from the first elastic part 113 and the second elastic part 114 to the opening of the U-shaped structure. In this case, the neck 104 can be advantageously pushed into between the first and second support plates 111 and 112 by the portions of the first and second elastic parts 113 and 114 to the opening of the U-shaped structure, and the neck 104 can be advantageously caught by the portions of the first and second elastic parts 113 and 114 to the closing of the U-shaped structure.

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

Fig. 3 shows a schematic view of the carrier means 10 in cooperation with the separating means 20 and the conveying device 800.

In some examples, the carrier mechanism 10 may include a plurality of support portions 11 (see fig. 3). In some examples, the number of supports 11 of the load bearing mechanism 10 may be 2, 4, or 8. For example, in the embodiment shown in fig. 3, the support portions 11 may be a first support portion 11a, a second support portion 11b, a third support portion 11c, and a fourth support portion 11 d.

In some examples, the bearing mechanism 10 may include a mounting table 12 for mounting the first support 11a, the second support 11b, the third support 11c, and the fourth support 11 d. In some examples, the first support 11a, the second support 11b, the third support 11c, and the fourth support 11d may be uniformly arranged at the mounting table 12 (see fig. 3).

In some examples, the plurality of support portions 11 of the carrier mechanism 10 may be located on the same circumference. For example, in the embodiment shown in fig. 3, 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 table 12 may be a circular platform. In the embodiment shown in fig. 3, the first support portion 11a, the second support portion 11b, the third support portion 11c, and the fourth support portion 11d may be uniformly arranged on the outer circumference of the mount table 12.

In some examples, the carrier mechanism 10 may push the bag container 100 to be uncapped in the left-right direction to the front of the separating mechanism 20. In various embodiments, the "left-right direction" may be understood as a direction substantially orthogonal to the "up-down direction" and substantially orthogonal to the "front-rear direction". In the embodiment shown in fig. 3, "to the left" or "to the left" may be understood as the direction indicated by D5, and "to the right" or "to the right" may be understood as the direction indicated by D6.

In some examples, the mount table 12 is configured to be rotatable about an axial center in the up-down direction, for example, in the direction of D5 or D6 shown in fig. 3, so that the mount table 12 of the support portion 11a, the support portion 11b, the support portion 11c, and the support portion 11D is rotated about the circumference to push the bag container 100 to be uncapped to the front of the separating mechanism 20 from the left or right side (see fig. 3). In some examples, the carriage mechanism 10 may further include a rotating motor (not shown), and the rotating motor may be used to drive the mounting table 12 to rotate around an axis in the up-down direction, for example, in the direction D5 or D6 shown in fig. 3.

In some examples, carrier mechanism 10 may cooperate with conveyor 800 to receive bag-type containers 100 from conveyor 800. Conveying device 800 may be a device for conveying bag-type containers 100, such as conveying bag-type containers 100 from a storage bin (not shown) to carrier mechanism 10. In the embodiment shown in fig. 3, conveyor 800 may convey bag-type containers 100 to carrier mechanism 10 one-by-one along direction D7. For example, conveyor 800 may interface with support portion 11 of carriage 10, i.e., an output port (not shown) of conveyor 800 is disposed opposite and engages support portion 11, thereby conveying bag-type container 100 to support portion 11 of carriage 10 and retaining in the U-shaped configuration of support portion 11.

In addition, carrier mechanism 10 may push bag-type container 100 received from conveyor 800 to separation mechanism 20 for decapping by rotating, e.g., carrier mechanism may push bag-type container 100 received from conveyor 800 to separation mechanism 20 by rotating in the direction D5 (see fig. 3). In this case, the cooperation of decapping device 1 with conveying device 800 may constitute a handling system for bag containers 100, which may be used for conveying bag containers 100 and for decapping bag containers 100.

Fig. 4A is a schematic diagram illustrating the separation mechanism 20 according to an example of the present invention abutting against the cap 102 of the bag-type container 100; fig. 4B is a schematic diagram illustrating separation of cap 102 from body 101 by separation mechanism 20 according to an example of the present invention;

fig. 4C is a schematic diagram illustrating separation of cap 102 from body 101 by separation mechanism 20 according to an example of the present invention.

In some examples, the separation 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 disposed opposite to each other. In some examples, the first arm 21 and the second arm 22 may be disposed side by side. In some examples, the first arm 21 and the second arm 22 may be disposed in parallel. In some examples, the first arm 21 and the second arm 22 may be in a thin plate shape (see fig. 4A, 4B, and 4C).

In some examples, the first arm 21 and the second arm 22 may have a predetermined spacing therebetween. In some examples, the predetermined spacing between the first and second arms 21, 22 may be less than a maximum width of the cap 102 and may be greater than a minimum width at the junction of the neck 104 and the cap 102, and the first and second arms 21, 22 may abut the cap 102 from below the cap 102 may be configured to abut the cap 102 from the junction of 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 the cap 102. In this case, by abutting 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 portion 101.

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

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

In some examples, the first arm 21 and the second arm 22 may rotate about an axial center in the left-right direction to separate the cap 102 from the main body portion 101 (see fig. 4C). In the embodiment shown in fig. 4C, the first arm 21 and the second arm 22 can be rotated in the direction D8 to separate the cap 102 from the body portion 101.

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 rotatable about the first shaft 210 and linked to each other, and the second arm 22 may 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 fig. 4A, 4B, and 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 the formation of a lever structure for uncapping the bag-type container 100.

In some examples, the first resistance arm 211, the first shaft 210, and the first power arm 212 of the first arm 21 may be formed in 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 may be formed in an L-shaped structure (see fig. 4A, 4B, and 4C). In this case, the first and second arms 21 and 22 formed in the L-shaped configuration can facilitate driving of the first and second power arms 212 and 222 when the first and second resistance arms 211 and 221 move in the front-rear direction.

In some examples, first resistance arm 211 and second resistance arm 212 may be disposed substantially parallel. That is, the pitches of the first resistance arm 211 and the second resistance arm 212 at the respective positions may be substantially maintained to be equal. In some examples, the first power arm 212 and the second power arm 222 may be substantially parallel. In some examples, the structure of the first arm 21 and the structure of the second arm 22 may be the same. In some examples, the first axis 210 and the second axis 220 may be co-linear. In some examples, the first arm 21 and the second arm 22 may be mirror symmetric.

In the embodiment shown in fig. 4A, 4B, and 4C, by driving the first shaft 210 and the second shaft 220 toward the front, the first resistance arm 211 and the second resistance arm 221 can be driven to the lower side of the cap 102 in the direction D3 (see fig. 4A and 4B); and by driving the first power arm 212 and the second power arm 222 toward the rear, the first resistance arm 211 and the second resistance arm 221 can be driven to rotate about the first shaft 210 and the second shaft 220 in the direction D8, so that the first resistance arm 211 and the second resistance arm 212 move toward a direction away from the main body portion 101, thereby separating the cap 102 from the main body portion 101 (see fig. 4C).

In some examples, when the first and second arms 21 and 22 are in an initial posture, such as the posture shown in fig. 4A, the first and second resistance arms 211 and 221 may be substantially in the front-rear direction, and the first and second power arms 212 and 222 may be substantially in the up-down direction (see fig. 4A). Thereby, it is possible to facilitate driving the first resistance arm 211 and the second resistance arm 221 to the lower side of the cap 102 in the front-rear direction.

In some examples, the separation mechanism 20 may include a holding member (not shown) that returns the first and second arms 21 and 22 to the initial posture. The holding member may be configured to provide a restoring force to the first and second arms to return to the initial posture. For example, the retaining member may be configured to provide traction towards the underside of the first and second resistance arms 211, 221 or towards the front of the first and second power arms 212, 222. In this case, the first arm 21 and the second arm 22 can be automatically returned to the initial postures after the uncapping is completed, so that the next uncapping operation can be performed. In some examples, the retaining member may be a resilient pull member, such as a tension spring.

In other examples, the moment of gravity on the first resistance arm 211 may be greater than the moment of gravity on the first power arm 212, and the moment of gravity on the second resistance arm 221 may be greater than the moment 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 postures by the action of gravity.

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

fig. 5C is a schematic diagram illustrating the driving mechanism 30 according to the example of the present invention driving the separation mechanism 20 to separate the cap 102 of the bag container 100 from the body 101.

In some examples, the drive mechanism 30 may include a drive shaft 31 (see fig. 1) driven by a drive motor (not shown).

In some examples, the drive mechanism 30 may drive the separation mechanism 20 to cause the first arm 21 and the second arm 22 of the separation mechanism 20 to abut against the cap 102 (see fig. 5A and 5B), and the drive mechanism 30 may drive the separation mechanism 20 to cause the first arm 21 and the second arm 22 to move in a direction away from the main body portion 101 to separate the cap 102 from the main body portion 101 (see fig. 5C).

In some examples, the drive mechanism 30 may be configured to drive the first and second arms 21 and 22 to move in the direction D3 to below the cap 102 (see fig. 5A and 5B), and the drive mechanism 30 may be configured to drive the first and second arms 21 and 22 to rotate in the direction D8 to separate the cap 102 from the body portion 101 (see fig. 5C).

In some examples, the first arm 21 may be connected to the transmission shaft 31 of the driving mechanism 30 by a first shaft 210, and the second arm 22 may be connected to the transmission shaft 31 of the driving mechanism 30 by a second shaft 220. In some examples, the drive mechanism 30 may move the first and second resistance arms 211 and 221 below the cap 102 by driving the first and second shafts 210 and 220 (see fig. 5A and 5B), and rotate the first resistance arm 211 about the first shaft 210 and the second resistance arm 221 about the second shaft 220 in a direction away from the body portion 101 by driving the first and second power arms 212 and 222 (see fig. 5C).

In some examples, the drive mechanism 30 may also include a guide 32 (see fig. 1). In some examples, the guide 32 may be disposed on the travel path of the first and second power arms 212, 222 (see fig. 5A, 5B, and 5C). In the embodiment shown in fig. 5A, 5B, and 5C, the guide 32 may be disposed on a travel path along which the first and second power arms 212, 222 move in the direction D3.

The driving mechanism 30 is configured to drive the first and second resistance arms 211 and 212 to move below the cap 102 in the direction D3 (see fig. 5A and 5B), and when the first and second power arms 212 and 222 reach the guide portion 32 and the first and second resistance arms 211 and 221 continue to travel toward the front (i.e., the direction indicated by D3 in fig. 5A and 5B), the guide portion 32 may guide the first and second power arms 212 and 222 so that the first and second power arms 212 and 222 have a travel component in the up-down direction, so that the first and second resistance arms 211 and 221 have a travel component in the up-down direction (see fig. 5C). In the embodiment shown in fig. 5C, the first arm 21 and the second arm 22 may rotate in the direction D8 around the first shaft 210 and the second shaft 220, respectively, guided by the guide portion 32, so that the first resistance arm 211 and the second resistance arm 221 move upward to be away from the main body portion 101, thereby separating the cap 102 from the main body portion 101.

In this case, by providing the guide portion 32 capable of guiding the first power arm 212 and the second power arm 222 on the travel path, it is possible to cause one driving mechanism 30 to generate two-dimensional acting force.

In some examples, the guide portion 32 may have a guide direction intersecting the front-rear direction (see fig. 5A, 5B, and 5C). In some examples, the guiding direction of the guide portion 32 may be obliquely downward toward the front (see fig. 5A, 5B, and 5C). In other examples, the guiding direction of the guide portion 32 may be in an up-down direction. In other examples, the guiding direction of the guiding portion 32 may be obliquely upward toward the front.

In some examples, the guiding direction of the guiding portion 32 may be along a diagonal up-down direction. For example, in the embodiment shown in fig. 5A, 5B, and 5C, the guiding direction of the guide portion 32 may be inclined downward along the direction D3. In this case, the first and second resistance arms 211 and 221 have a travel component in the up-down direction by guiding the first and second power arms 212 and 222 to move in the guide direction intersecting the front-back direction.

In the present embodiment, the guiding direction of the guide portion 32 may refer to an extending direction of the guide surface of the guide portion 32. The guide surface of the guide portion 32 may extend in the up-down direction or in the oblique up-down direction. For example, in the embodiment shown in fig. 5A, 5B, and 5C, the guide surface of the guide portion 32 may extend obliquely downward along the direction D3. In this case, the first power arm 221 and the second power arm 222 may move along the guide surface of the guide portion 32 to be guided.

In some examples, the guide surface of the guide 32 may be a smooth plane. In other examples, the guide surface of the guide portion 32 may be a smooth curved surface.

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

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

In some examples, an end of the second power arm 222 distal from the second resistance arm 221 may protrude toward a side distal from the first power arm 212 to form an ear (not shown). In this case, the guide portion 32 located on the side of the propeller shaft 31 can guide the second power arm 222 by the ear portion facing the side. In some examples, the ears of the second power arm 222 may be cylindrical.

In the embodiment shown in fig. 5A, 5B, and 5C, guide 32 may guide first and second power arms 212, 222 to cause first and second power arms 212, 222 to have a downward-facing component of travel, to cause first and second arms 21, 22 to rotate about first and second shafts 210, 220, respectively, in the direction D8, to cause first and second resistance arms 211, 221 to have an upward-facing component of travel.

In some examples, when the first and second power arms 212 and 222 are guided by the guide portion 32 to move rearward and downward with respect to the first and second shafts 210 and 220 (see fig. 5A, 5B, and 5C), the first and second power arms 212 and 222 can be facilitated to be guided by the guide portion 32 by providing an escape space on the transmission shaft 31 in a direction toward the rear and downward.

Fig. 6A is a schematic diagram illustrating another example of a bag-type container 100 in accordance with an example of the present invention positioned in front of a separation mechanism 20; fig. 6B is a schematic diagram showing another example in which the drive mechanism 30 according to an example of the present invention drives the separation mechanism 20 to abut against the cap 102 of the bag-type container 100; fig. 6C is a schematic diagram showing another example in which the drive mechanism 30 according to an example of the present invention drives the separation mechanism 20 to separate the cap 102 of the bag container 100 from the body 101.

In some examples, the guiding direction of the guide portion 32 may be obliquely upward toward the front (i.e., the direction indicated by D3 in fig. 6A and 6B) (see fig. 6A, 6B, and 6C).

In the embodiment shown in fig. 6A, 6B, and 6C, the guide 32 may guide the first and second power arms 212, 222 such that the first and second power arms 212, 222 have an upward-facing component of travel, and such that the first and second resistance arms 211, 221 have an upward-facing component of travel, thereby separating the cap 102 from the body portion 101.

In the embodiment shown in fig. 6A, 6B and 6C, the first arm 21 and the second arm 22 may be in the shape of a straight line. In the embodiment shown in fig. 6A, 6B, and 6C, the first arm 21 and the second arm 22 may have a long plate shape. In some examples, the end of the first resistance arm 211 distal from the first power arm 212 may have a rounded design. In some examples, the end of the second resistance arm 221 distal from the second power arm 222 may have a rounded design.

In the embodiment shown in fig. 6A, 6B, and 6C, when the first and second arms 21 and 22 are in the initial posture, such as the posture shown in fig. 6A, the first resistance arm 211, the first power arm 212, the second resistance arm 221, and the second power arm 222 may be substantially along the front-rear direction (see fig. 6A).

Fig. 7A and 7B are schematic diagrams illustrating the engagement of the driving mechanism 30 with the carrying mechanism 10 according to an example of the present invention, in which fig. 7A is a schematic diagram illustrating the driving mechanism 30 before moving forward, and fig. 7B is a schematic diagram illustrating the driving mechanism 30 after moving forward.

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 the base may be used to mount the drive motor and the guide 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 may be a separate component from drive mechanism 30, and carrier mechanism 10 and/or drive mechanism 30 may be mounted to the base.

In some examples, the drive shaft 31 of the drive mechanism 30 may be elongated, such as a prism, a cylinder, or the like, extending along the axial direction. The transmission shaft 31 may have a first end 311 connected with the separation mechanism 20 and a second end 312 opposite to the first end 311 (see fig. 7A and 7B).

In some examples, the carrier 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 portion 312 (see fig. 7A).

In the embodiment shown in fig. 7A and 7B, the first support portion 11a may hold a pouch container 100 to be uncapped, and the third support portion 11c may hold a pouch container 100 that has been uncapped.

In some examples, drive shaft 31 is moved toward the front (i.e., the direction indicated by D3 in fig. 7A) to cause first end 311 to drive separation mechanism 20 to uncap bag-type container 100 carried on first support 11a and to cause second end 312 to remove bag-type container 100 carried on third support 11c (see fig. 7B). In this case, the bag-type container 100 carried on the first support portion 11a can be uncapped and the bag-type container 100 carried on the third support portion 11c can be removed at the same time by moving the drive shaft 31 toward the front, whereby the structural design can be simplified.

In some examples, as drive shaft 31 moves forward, second end 312 of drive shaft 31 may abut neck 104 of bag-type container 100 gripped by third support portion 11c, and in turn, be pushed away from third support portion 11c by second end 312 of drive shaft 31, thereby removing uncapped bag-type container 100 from carrier 10.

In some examples, the carrier mechanism 10, the drive mechanism 30 may cooperate with the dispensing device 900 to push the uncapped bag-type container 100 to the dispensing device 900 (see fig. 7A and 7B). The liquid preparation apparatus 900 may be an apparatus for preparing a liquid medicine from the bag container 100, for example, mixing another liquid medicine with the liquid medicine in the bag container 100.

The carrier mechanism 10 may rotate the uncapped bag container 100 to the vicinity of the dispensing device 900 by rotation, and then the drive mechanism 30 may remove the bag container 100 from the carrier mechanism 10 and push it to the dispensing device 900 (see fig. 7B). In this case, the uncapping apparatus 1, the transfer apparatus 800, and the liquid dispensing apparatus 900 may constitute an automatic liquid dispensing system that may be used to transfer the bag container 100, uncap the bag container 100, and mix another liquid medicine with the liquid medicine in the bag container 100.

In some examples, the decapping device 1 can further include a retrieval mechanism (not shown) disposed below the first and second arms 21, 22. The removed cap 102 can slide down to the recovery mechanism via the first arm 21 and the second arm 22 inclined in the oblique up-down direction. In this case, the cap 102 removed can be easily recovered by the first and second arms 21 and 22 inclined in the oblique up-down direction and the recovery mechanism provided below the first and second arms 21 and 22.

Fig. 8 is a schematic flow chart showing the uncapping process of the bag container 100 by the uncapping apparatus 1 according to the example of the present invention. Hereinafter, a flow of uncapping the bag container 100 by the uncapping apparatus 1 according to the present embodiment will be described in detail with reference to fig. 8.

In the present embodiment, as shown in fig. 8, the flow of uncapping the bag-type container 100 by the uncapping apparatus 1 may include the steps of: fixing the bag container 100 to the carrier mechanism 10 (step S100); pushing the pouch container 100 to be uncapped to the front of the separating mechanism 20 (step S200); driving the separation mechanism 20 to abut against the cap 102 of the bag container 100 (step S300); the separation mechanism 20 is driven to separate the cap 102 of the bag container 100 from the main body 101 (step S400).

In some examples, in step S100, carrier mechanism 10 may clamp neck 104 of bag-type container 100 through support portion 11 according to examples of the present invention, thereby fixing bag-type container 100. In step S100, the bag container 100 to be uncapped may be conveyed to the carrier 10 by the conveying device 800 according to the present example, and the supporting portion 11 of the carrier 10 may clamp the neck 104 of the bag container 100 to be uncapped so that the cap 102 is exposed upward.

In some examples, in step S200, the carrier mechanism 10 may push the bag-type container 100 in the left-right direction to the front of the separation mechanism 20 by rotating.

In some examples, in step S300, the driving mechanism 30 may drive the separation mechanism 20 to move toward the front to abut against the cap 102 from below. In step S300, the driving mechanism 30 may drive the first shaft 210 and the second shaft 220 according to the present example to move forward, thereby abutting the first resistance arm 211 and the second resistance arm 221 against the cap 102 from below.

In some examples, in step S400, the driving mechanism 30 may drive the first and second arms 21 and 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-type container 100 from the body portion 101. In step S400, the driving mechanism 30 may 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 portion 32 provided on the travel path toward the front, to rotate the first arm 21 and the second arm 22 about the first shaft 210 and the second shaft 220, respectively, to move the first resistance arm 211 and the second resistance arm 212 in a direction away from the body portion 101, thereby separating the cap 102 of the bag-type container 100 from the body portion 101. In addition, in step S400, the removed cap 102 may slide down to the recovery mechanism from the first resistance arm 211 and the second resistance arm 221 along the oblique up-down direction.

While the present invention has been described in detail in connection with the drawings and examples, it is to be understood that the above description is not intended to limit the invention in any way. The present invention may be modified and varied as necessary by those skilled in the art without departing from the true spirit and scope of the invention, and all such modifications and variations are intended to be included within the scope of the invention.
